Precautions for small single punch tablet press

Small single punch tablet press can press all kinds of granular raw materials into round tablets, which is suitable for laboratory trial production or small batch production of various tablets, sugar tablets, calcium tablets, special-shaped tablets, etc It is a small table type electric (manual) continuous tablet pressing machine, which is equipped with a pair of stamping dies, and the filling depth and tablet thickness of materials can be adjusted We can provide all kinds of molds according to customers' requirements So what are the precautions when using a small single punch tablet press? Today, I made some summary for you, hoping to help you: 1 Before the first use, please read the manual carefully against the actual machine, and then use it again 2 The machine can only be operated in a certain direction (see the arrow on the hand wheel or protective cover), and can not be reversed to avoid damage to the parts Pay special attention to the adjustment of pressing plate, and do not neglect it 3 Belt tension adjustment: adjust through two adjusting nuts on the electromechanical bottom plate Pay attention to locking after adjustment 4 When there is no power supply, use hand to press the tablet, and remove the V-belt to reduce resistance and wear But do not remove the large pulley, because the large pulley has the effect of flywheel labor-saving 5 When pressing the electric tablet, the rotating handle on the hand wheel must be pulled down to avoid personal injury during operation 6 Whether manual or electric pressing, make the upper punching core rod in the rising position before starting If the upper punching plate is started in the down position, it will enter into the middle molding plate just after starting At this time, because the rotation speed of the machine has not yet risen up and the inertia is small, it is easy to have a car jacking (that is to say, after the upper punch enters the middle die, the machine is "jacked" due to the resistance of the tablet, so that the machine stops running Because of the heavy load when jacking the car, the mechanical analysis is often damaged or the motor is burnt out) 7 Handling method after car jacking (1) in case of car jacking during electric tablet pressing, turn off the power immediately to avoid burning the motor (2) when the jacking condition is light, turn the hand wheel with the hand wrench to make the upward punch pass the "dead point" (but not reverse, so as to avoid repeated feeding of the feeder, resulting in more serious jacking) (3) in case of serious jacking, loosen the lock nut of the connecting rod, turn the upper core punching rod to make it rise to reduce the pressure, and then turn the hand wheel to eject the tablet Then readjust the tablet hardness 8 In the process of tablet pressing, the quality (weight, hardness, surface finish, etc.) of tablets must be checked frequently 9 The proportioning and granulating process before tablet pressing has a great impact on tablet pressing For example, the formulation and granulation of auxiliary materials such as drug and slide materials, fillers and binders (powder condition, particle tightness, powder particle proportion, water content, etc.) have a direct impact on the quality of tablets And often due to the improper pelletizing of ingredients, it can not be flaked, or even damage the machine Therefore, this machine can not be used for pressing semi-solid or moist or particle free ultra-fine powder In use, if the pressure has been adjusted to a considerable extent, it can not be pressed into pieces or it is pressed into pieces, but it appears too loose, delamination, debris, pockmarks, powder falling and other phenomena We should find out the reasons and solve them from the aspects of ingredients Never adjust and increase the pressure to damage the machine In addition, the hardness of some tablets pressed out by the materials is not big, but it has certain toughness, and its falling and city making property is not bad (usually falling from 1-1.2m height to the ground without breaking) Therefore, it should not only focus on the hardness to meet the requirements of transportation and storage, so as to avoid too much pressure on the tablets and damage to the machine.
