Description

Technical Field

[0001] The utility model relates to the field of capsule production and manufacturing, and more particularly to a circulating claw pushing mechanism for a capsule machine. Background Art

[0002] The capsule machine is a specialized piece of equipment for producing hollow hard capsules. During the capsule production process, multiple needle molds are fixed to a mold bar to form a needle mold assembly. After being dipped in glue, the needle molds on the assembly are raised to the machine's platform via the machine's lifting mechanism. Then, a push claw pushes the glued needle mold assembly to a preset position on the platform to complete the subsequent conveying, lowering, demolding, cutting, fitting, oiling, and gluing processes. After pushing a needle mold assembly, the push claw returns to its original position and waits for the next needle mold assembly to arrive before pushing it in. Furthermore, the next needle mold assembly must wait until the push claw has fully retracted before it can be raised to the push position. This waiting time significantly affects the push claw's rhythm, impacting production efficiency. The push claw's movement rhythm directly determines the entire capsule machine's production rhythm. Therefore, improving the push claw's movement rhythm is crucial. Utility Model Content

[0003] The purpose of the utility model is to provide a circulating pushing claw mechanism for a capsule machine, thereby solving the problem in the prior art that the capsule production efficiency is low due to the long movement rhythm of the pushing claw.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A circulating pushing claw mechanism for a capsule machine is provided, comprising: a servo motor; a pair of synchronous pulleys, wherein the output shaft of the servo motor is connected to one of the synchronous pulleys; a synchronous belt sleeved on the pair of synchronous pulleys; a pair of annular track brackets, wherein the pair of annular track brackets clamp the synchronous pulleys and the synchronous belt in the middle, and the annular track brackets have an annular track; and a pushing claw assembly fixedly connected to the surface of the synchronous belt, wherein the pushing claw assembly is an axially symmetrical structure, comprising: a pushing claw bracket, and a pair of pushing claws protruding and extending from both ends of the pushing claw bracket, wherein the two ends of the pushing claw bracket are respectively slidably connected to the annular track of the pair of annular track brackets; wherein, driven by the servo motor, the pushing claw assembly circulates along the annular track of the annular track bracket, and the needle module is pushed by the pushing claws.

[0006] Preferably, the annular track of each annular track bracket includes: a first linear track portion and a second linear track portion extending parallel and spaced apart above and below, and a first arcuate track portion and a second arcuate track portion extending symmetrically on the left and right sides.

[0007] Preferably, the circulating pawl mechanism includes two pawl assemblies, and when one pawl assembly moves to the top of the annular track bracket, the other pawl assembly moves to the bottom of the annular track bracket.

[0008] Preferably, the push claw protrudes and extends outside the annular track bracket.

[0009] The utility model improves the original reciprocating push claw into a circulating push claw. After the previous needle module is pushed away by the push claw, the next needle module can directly rise to its position. The push claw runs one circle along the circular track and then returns to the end of the next needle module to directly push the next needle module. In this process, the return time of the push claw is saved, and the production efficiency is improved.

[0010] In summary, the utility model provides a rationally constructed circulating push claw mechanism, which improves the production efficiency of the capsule machine by shortening the movement rhythm of the push claw and has good application prospects in the field of capsule production and manufacturing.

[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0017] like Figure 1 FIG. 1 shows a circulating claw mechanism according to a preferred embodiment of the present invention, comprising a servo motor 1, a synchronous pulley 2, a synchronous belt, annular track brackets 3, 3' and claw assemblies 4, 4'.

[0018] Among them, the output shaft of the servo motor 1 is connected to one of the synchronous pulleys 2. The synchronous pulley connected to the servo motor 1 is the driving pulley, and the other unconnected is the driven pulley. The synchronous belt is an annular belt with equidistantly distributed transverse teeth on the inner surface. The two ends of the synchronous belt are respectively sleeved on the synchronous pulley 2. It should be understood that in order to facilitate the illustration of the internal structure, Figure 1 Therefore, under the drive of the servo motor 1, the synchronous pulley 2 and the slot of the synchronous belt are engaged with each other to transmit power, thereby realizing the transmission of the synchronous belt.

[0019] Annular track brackets 3, 3' are respectively along Figure 1 The annular track bracket 3 is arranged parallel to the front-to-back direction of the frame, with the synchronous pulley 2 and the synchronous belt sandwiched therebetween. The annular track comprises a first linear track portion 31 and a second linear track portion 32 extending parallel to each other at intervals above and below, and a first curved track portion 33 and a second curved track portion 34 extending symmetrically to the left and right sides.

[0020] The push claw assemblies 4, 4' are each fixedly connected to the surface of the synchronous belt. Specifically, the push claw assemblies 4, 4' are axisymmetric structures, including a push claw bracket 41 and a pair of push claws 42 extending from each end of the push claw bracket 41. The ends of the push claw bracket 41 are respectively slidably connected to the annular track of the annular track bracket 3. Therefore, driven by the servo motor 1, the push claw assemblies 4, 4' are driven by the synchronous belt to circulate along the annular track of the annular track bracket 3, that is, they slide along the first linear track portion 31, the first curved track portion 33, the second linear track portion 32, and the second curved track portion 34. The push claws 42 protrude from the outer sides of the annular track brackets 3, 3', thereby conveniently pushing the needle module 10.

[0021] When one push claw assembly 4 moves above the circular track bracket, the other push claw assembly 4' moves below the circular track bracket. Therefore, during the operation of the capsule machine, after the previous needle module is pushed away by the push claw, the next needle module can directly rise into place. The push claw rotates along the circular track once, then returns to the end of the next needle module and directly pushes the next needle module. This process saves the push claw's retraction time and improves capsule production efficiency.

[0022] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. Various modifications are possible to the above embodiments of the present invention. Any simple, equivalent changes and modifications made in accordance with the claims and description of the present invention fall within the scope of protection of the present invention. Anything not fully described in this invention represents conventional technology.
