Description

Technical Field

[0001] The utility model relates to an anti-jamming structure, specifically to an anti-jamming structure for a capsule feeding device. Background Art

[0002] The Chinese patent with the application number CN202221704036.4 provides a patent named "Feeding Device for Capsules". In this solution, capsules are first placed in a feed hopper. The rotating shaft is driven to rotate by a rotating motor. The capsules in the guide box fall from the through hole between two adjacent partition plates. Then, each partition plate is rotated continuously so that the capsules are discharged through the discharge port and fall on the conveyor belt. The conveyor belt is driven to rotate by a conveyor motor, so that the capsules on the conveyor belt move towards the cylinder. Each capsule enters the cylinder through each upper opening and is located between two adjacent partition pieces, effectively improving the efficiency. The discharge motor drives each partition piece to rotate, so that the capsules fall through the lower opening, thus completing the feeding of the capsules. This technical solution effectively avoids the continuous entry of capsules into the transmission pipe through components such as partition plates, cylinders, and partition pieces, making the transmission smoother. However, there are still the following problems: the feed hopper gradually becomes smaller from top to bottom, resulting in jamming at the discharge end at the lower end of the feed hopper. Moreover, there is no mechanism for cleaning jamming at the feed hopper. When feeding, the feed hopper will be filled with capsules. Therefore, once jamming occurs, all the capsules in the feed hopper need to be cleared out before dealing with the jamming at the discharge end of the feed hopper. This structural defect not only greatly reduces the feeding efficiency but also increases the labor intensity of the operator.

[0003] Therefore, those skilled in the art are committed to providing an anti-jamming structure for a capsule feeding device that can effectively solve the above technical problems. Summary of the Utility Model

A material discharging channel 10 is formed between the material limiting seat 9 and the discharging end of the hopper 5. The lower end of the material limiting seat 9 is connected to the upper ends of two guiding members 11. The lower ends of the guiding members 11 are connected through a fixing ring 12;

[0036] A guide ring 13 is provided below the hopper 5. Connecting rods 15 are provided on both sides of the guide ring 13, and each connecting rod 15 is connected to the lower end of the hopper 5. Two guide grooves 16 are provided on the inner wall of the guide ring 13, and each guide member 11 is slidably located at each guide groove 16.

[0037] The adjustment handle 7 includes a rod body 21. The inner side of the rod body 21 is connected to the ejector rod 8, and the outer side of the rod body 21 extends out of the barrel 3 and is provided with a handle 22. The material limiting seat 9 is conical, and a material ejecting rod 23 is provided at the upper end of the material limiting seat 9. The guide member 11 includes a guide rod 26. The lower end of the guide rod 26 is connected to the fixed ring 12. A clamping block 27 is provided on the upper half of the guide rod 26.

[0038] A weight reduction hole 30 is provided at the lower end of the ejector rod 8. The lower end of the hopper 5 is detachably provided with an extension hopper 31. The extension hopper 31 is located inside the barrel 3. The lower half of the hopper 5 is made of a transparent material, so as to facilitate checking whether there is material blockage and whether the material discharging is smooth. The positioning plate 1 is connected to the upper end of the box body 32 through four positioning holes 18 and is communicated with a material guiding box 33 arranged inside the box body 32.

[0039] A positioning groove 35 adapted to the size of the positioning plate 1 is provided at the upper end of the box body 32.

The output ends of the jacking power sources are respectively connected to the outer sides of the adjustment handles 7, and the ejector rod 8 is driven to move up and down through each adjustment handle 7. According to actual use requirements, the up and down movement of the ejector rod 8 can also be realized by a jacking power source (cylinder).

[0040] The optimal working principle of the present utility model is as follows:

[0041] When feeding is required, first place the capsules in the hopper 5. The capsules in the hopper 5 will enter the barrel 3 through the feeding channel 10. The capsules that enter the barrel 3 will continue to fall for the feeding process. The feeding channel 10 is formed between the discharge end of the hopper 5 and the material limiting seat 9. When blockage occurs at the feeding channel 10, the adjusting handle 7 can be pulled by hand at this time, so that the adjusting handle 7 drives the material limiting seat 9 to move upward. By moving the material limiting seat 9 upward, the distance between the material limiting seat 9 and the discharge end of the hopper 5 is enlarged, thereby expanding the feeding channel 10 to solve the problem of material jamming. During specific use, after moving the material limiting seat 9 upward to solve the problem of material jamming, the upward pulling force on the adjusting handle 7 can be no longer applied, so that the material limiting seat 9 returns downward, and the entire feeding device continues to operate without affecting the feeding efficiency. If blockage occurs again after the return, the feeding port can be enlarged upward again to enable smooth feeding. At the same time, stop feeding the hopper 5. When all the capsules in the hopper 5 have been discharged, then return the material limiting seat 9 to its position. After the return is completed, continue to feed the hopper 5. Through the above settings, the discharge speed of the feeding channel 10 can be controlled, thereby effectively avoiding excessive accumulation of capsules in the guide box 33, making the feeding smoother, and at the same time, it can also solve the problem that is difficult to handle after blockage at the discharge end of the hopper.

[0042] When the present utility model is in use, there are two specific usage methods. One is to directly connect the discharge end of the barrel 3 to the input end of the transmission pipe (not shown in the figure). When the capsules enter the transmission pipe, the capsules in the transmission pipe are transmitted by the blower connected to the transmission pipe.

[0043] As a further preference, another method is to install the present utility model on the capsule feeding device 100 for use. The capsule feeding device 100 has basically the same patent structure as the patent with the application number CN202221704036.4 and the name "Feeding Device for Capsules". The difference is that the feeding hopper structure in CN202221704036.4 is replaced with the present utility model to solve the blockage problem. The specific structure and usage method of the feeding device for capsules (capsule feeding device 100) have been described in detail in the Chinese patent of CN202221704036.4 and will not be elaborated here. The modification cost of the present utility model when used in combination with the feeding device 100 is low, and only the feeding hopper in CN202221704036.4 needs to be replaced with the present utility model.

[0044] The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present utility model through logical analysis, reasoning or limited experiments on the basis of the prior art shall fall within the protection scope determined by the claims.
