DETAILED DESCRIPTION

[0028] The tablet press is composed of a frame 1, a die holder 2, a pressing cylinder 3, a pressing head 4, a feeding auger 5, a material bin 6, a feeding cylinder 7 and a plunger 8. The die holder 2 is arranged on the frame 1, and the die holder 2 is longitudinally and evenly provided with die holes 9 on the top of the die holder 2 to press and form tablets in the die holes 9. The size of the die holes 9 is equal to the diameter of the tablets. The pressing cylinder 3 is installed on the die holder 2 through a support, and the piston rod end of the pressing cylinder 3 is correspondingly installed with a plurality of pressing heads 4 through a support plate and the die holes 9. The pressing cylinder 3 drives the support to move downward, and then drives the pressing heads 4 to move downward, so that the pressing heads 4 are inserted into the die holes 9, and the raw materials in the die holes 9 are extruded and formed by the pressing heads 4. The die holder 2 outside the die holes 9 is provided with the feeding auger 5, and the die holder 2 at one end of the feeding auger 5 is provided with the material bin 6. The material bin 6 is communicated with the feeding auger 5 to supply the feeding auger 5 with raw materials through the material bin 6. The material bin 6 can store raw materials, so that the feeding auger 5 can be continuously supplied with raw materials, and the continuous working capacity of the tablet press is maintained. The bottom of the feeding auger 5 is correspondingly provided with a plurality of feeding holes 10, and the bottom of the feeding hole 10 is provided with a plunger hole 11. The plunger hole 11 is arranged in an inverted T shape with the feeding hole 10 and is communicated with the die hole 9. The feeding auger 5 supplies the plurality of feeding holes 10 with raw materials respectively, so that the raw materials can enter the plunger hole 11 through the feeding auger 5, the feeding hole 10 and the plunger hole 11 in turn. The frame 1 on both sides of the die holder 2 is respectively provided with the feeding cylinder 7, and the piston rod end of the feeding cylinder 7 is evenly installed with the plunger 8 through a cross beam. The plunger 8 is inserted and connected with the plunger hole 11. The feeding cylinder 7 drives the cross beam, and then drives the plunger 8 to move in the plunger hole 11, so that the raw materials in the plunger hole 11 are pushed by the moving plunger 8 to move into the die hole 9, thereby feeding the die hole 9 and enabling the raw materials to enter the die hole 9 and be pressed and formed in the die hole 9. Since the feeding auger 5 cooperates with the plunger 8 to simultaneously feed a plurality of die holes 9, and the plurality of pressing heads 4 can simultaneously press and form the raw materials in the plurality of die holes 9, a plurality of tablets can be produced at one time, thereby effectively improving the pressing efficiency, greatly improving the production capacity and effectively meeting the production needs of enterprises. The diameters of the feeding hole 10, the plunger hole 11 and the die hole 9 can be adjusted through bushings respectively. By adjusting and controlling the diameters of the feeding hole 10 and the plunger hole 11, the amount of raw materials can be controlled. By adjusting and controlling the diameter of the die hole 9, the diameter and thickness of the pressed tablets can be controlled.

[0029] The inner side end face of the plunger 8 is in an arc shape to close the die hole 9 through the plunger 8, thereby avoiding the raw materials from entering the plunger hole 11 during the pressing process, causing inaccurate raw material quantity. At the same time, since the inner side end face of the plunger 8 is in an arc shape, the pressing head 4 can pass through the plunger 8, ensuring that the plunger 8 does not easily affect the downward movement of the pressing head 4 during the process of closing the plunger hole 11.

[0030] The machine frame 1 on the bottom of the die holder 2 is provided with a discharging cylinder 12 through a support, the end of the piston rod of the discharging cylinder 12 is provided with a plurality of support rods 13 through a support plate and corresponding to the die hole 9, the top end of the support rod 13 extends into the die hole 9, the end of the support rod 13 extending into the die hole 9 is provided with a pressure bearing piston 14, and the pressure bearing piston 14 is in sliding sealing connection with the die hole 9. The pressure bearing piston 14 is used to extrude the raw material through the cooperation of the pressure bearing piston 14 and the pressure head 4, so as to extrude and form the raw material in the die hole 9 between the pressure bearing piston 14 and the pressure head 4. The discharging cylinder 12 is used to drive the support rod 13 to move, and then drive the pressure bearing piston 14 to move, so as to push the tablets upwards through the moving pressure bearing piston 14 after extrusion and forming, and push the tablets out of the die hole 9 to discharge the tablets. The pressing cylinder 3, the discharging cylinder 12 and the feeding cylinder 7 are electric cylinders, so as to accurately control the positions of the plunger 8 and the pressure bearing piston 14 and accurately control the stroke and the pressing force of the pressing cylinder 3.

[0031] The die hole 9 below the pressure bearing piston 14 is provided with a retreat stop flange 15, so as to bear the pressure on the pressure bearing piston 14 in the pressing process through the retreat stop flange 15.

[0032] The height (thickness) of the pressure bearing piston 14 is greater than or equal to the diameter of the plunger hole 11, so that the pressure bearing piston 14 can close the plunger hole 11 during feeding to the plunger hole 11, the plunger 8 and the pressure bearing piston 14 close both ends of the plunger hole 11, so as to control the feeding amount.

[0033] The die holder 2 is provided with a longitudinal transverse sliding groove 16 on the top end face, and the transverse sliding groove 16 is in communication with the die hole 9 on both sides of the die holder 2 respectively. The machine frame 1 on one side of the die holder 2 is provided with a pushing cylinder 17, the end of the piston rod of the pushing cylinder 17 is provided with a push plate 18 through a cross beam, and the push plate 18 is in plug-in connection with the transverse sliding groove 16; the other side of the die holder 2 is provided with a discharging conveyor belt 19. The pushing cylinder 17 is used to drive the push plate 18 to move through the pushing cylinder 17, and then drive the tablets to move towards the discharging conveyor belt 19 through the moving push plate 18, so as to push the tablets to the discharging conveyor belt 19 to discharge the tablets.

[0034] The bottom end face of the pressure head 4 is provided with a male die 20. The male die 20 is a cross die, so as to form a cross mark through stamping, thereby facilitating uniform cutting of the tablets through the cross mark. The male die 20 is a character die, so as to form characters through stamping, and the company name or brand name is stamped on the tablets.

[0035] The tablet press works, start the discharging cylinder 12, the discharging cylinder 12 is driven to each pressure-bearing piston 14 uplink through the support rod 13, and the plunger hole 11 is blocked. After the plunger hole 11 is blocked, start the feeding auger 5, the feeding auger 5 feeds the raw materials in the hopper 6 to each feeding hole 10, and then feeds the raw materials to the plunger hole 11. After the feeding of the plunger hole 11 is completed (for a period of time), the pressure-bearing piston 14 resets to open the plunger hole 11. After the pressure-bearing piston 14 resets, start the feeding cylinder 7, the feeding cylinder 7 pushes each plunger 8, and then pushes the raw materials into the die hole 9 until the inside end face of the plunger 8 is flush with the inner wall of the die hole 9. After the feeding is completed, start the pressing cylinder 3, the pressing cylinder 3 drives each pressure head 4 to descend and insert into the die hole 9, and the raw materials are pressed into shape through the cooperation of the pressure head 4 and the pressure-bearing piston 14. After the tablets are formed, reset the pressure head 4, after the pressure head 4 resets, start the discharging cylinder 12, the discharging cylinder 12 drives the tablets uplink through the support rod 13 and the pressure-bearing piston 14, so that the tablets enter the horizontal sliding groove 16. After the tablets are in place, start the pushing cylinder 17, the pushing cylinder 17 pushes the tablets to slide in the horizontal sliding groove 16 through the push plate 18, pushes the tablets to the discharging conveyor 19, and transfers the tablets to the next process through the discharging conveyor 19.

[0036] The tablet press can conveniently feed through the feeding auger 5, and can simultaneously feed multiple die holes 9 through the feeding auger 5 cooperating with the plungers 8, and then can simultaneously press multiple tablets after feeding through multiple pressure heads 4, thereby effectively improving the pressing efficiency, greatly improving the production capacity, meeting the efficient production needs of enterprises, and reducing the production cost. Through the hopper 6, the raw materials can be reserved for standby, ensuring the continuous working ability of the tablet press, so that it does not need to frequently supplement the raw materials. The problem of low pressing efficiency and limited production capacity of the existing tablet pressing device is solved.
