[0001] The invention relates to the technical field of tablet presses, in particular to a rotary tablet press for forming double-color fishing baits. Background Art

[0002] The operation process of the double-pressing double-material tablet press in the prior art is as follows: the first feeder adds the first material into the punching hole, and the first pair of pressing wheels pre-presses the material, and then the turntable rotates, and the second feeder adds the second material into the punching hole and then the second pair of pressing wheels press the material into shape. In this operation mode, only the first material is pressed for the first time, and the second pressing is mainly for the second material. Because the connection between the two materials is poor, the texture of each material is relatively soft.

[0003] The current tablet press method produces relatively soft products after molding, and can only press some products with smaller diameters. However, some products require a hard texture, such as fish bait. If the pressed product has a soft texture, the fish bait will easily break in the water and cannot be used for a long time.

[0018] 2. The open structure of the forced feeder of the present invention can increase the diameter of the feeding pipe and facilitate feeding. The single impeller can move the material for forced feeding. The half-open and half-sealed structure not only solves the problem that the open feeder is difficult to feed, but also solves the problem of material blockage in the sealed feeder. Materials with poor fluidity can be fed quickly and smoothly, ensuring the reliability of use and improving work efficiency.

[0019] 3. The material bin of the present invention has a simple structure, is easy to manufacture, and has low cost.

[0022] 6. The support legs of the present invention can be adjusted in height in a simple manner. The lower support does not need to be disassembled during adjustment. The height adjustment can be completed by rotating the upper support. The locking nut is used, and the locking method is simple and firm, and the disassembly and assembly are convenient and quick.

[0023] 7. The present invention provides a copper substrate under the bottom plate. Since the material bin will come into contact with the turntable during use, and copper is softer than iron, the copper substrate will be worn during use, thereby avoiding wear between the bottom plate and the turntable of the tablet press and protecting the equipment.

[0024] 8. The present invention is provided with a middle mold, and the product is stamped and formed in the middle mold. The middle mold is convenient to disassemble and replace. According to different processed products, only the middle mold needs to be replaced, which is easy to use and saves costs.

[0046] like Fig.12 As shown, the material bin 4 includes a ring 401 and a bottom plate 402.

Since the material bin 4 is frequently disassembled during use, after the feeder platform 5 is added, the support leg 6 does not need to be disassembled each time the material bin 4 is disassembled, and the height of the support leg 6 will not change, so that the tedious height adjustment of the support leg 6 each time disassembly can be avoided, and the disassembly and assembly is faster and convenient for maintenance.

[0050] like Fig.10 As shown, the support leg 6 includes an upper support 601, a locking nut 602, and a lower support 603.

Materials are added to the forced feeder 13 through the blanking barrel 11, which facilitates the control of the flow of materials and ensures smooth feeding.

[0056] Taking the two-color bait as an example, when it is used, the main motor 16 transmits power to the reducer 15 through the belt, the reducer 15 drives the main shaft 21 to rotate, and the turntable 17 rotates with the rotation of the main shaft 21, and feeds the material into the forced feeder 13 through the blanking barrel 11. The material in the first forced feeder 13 is added to the middle mold 174 under the action of the impeller 10. With the rotation of the turntable 17, the second forced feeder 13 adds the second material to the second forced feeder 13. With the rotation of the turntable 17, when the upper end of the upper punch 22 contacts the upper pre-pressing wheel 122, the upper end of the upper punch 22 contacts the upper pre-pressing wheel 122. When the lower end of the lower punch 23 contacts and cooperates with the lower pre-pressing wheel 191, due to the change of the trajectory, the upper and lower punches are squeezed toward the middle at the same time under the action of the upper and lower pressing wheels to complete the stamping and forming of the material, and then the upper and lower punches are stamped again through the upper main pressing wheel 123 and the lower main pressing wheel 192 to compact the material, and the turntable 17 continues to rotate. When it turns to the position of the baffle 141, the lower punch 23 moves upward along the trajectory on the lower guide rail 19 to push the product out of the stamping hole 175, and then passes through the baffle 141. The product falls along the discharge chute 18 and is collected. By forcing the feeder 13 to be arranged adjacent to each other and the main pressing wheel to be arranged adjacent to the pre-pressing wheel, the material is pre-pressed and pressed continuously to ensure that the final product has a hard texture, which can meet the requirements of products such as fish bait and ensure the reliability of the product in use; the tablet press can produce products with larger tablet diameter, larger filling depth and harder texture than existing products, which solves the limitation that the current tablet press can only produce tablets with small diameter and soft texture, and the product manufacturing range is wider and more practical.
