Description

Technical Field

[0001] The utility model relates to the technical field of conveying wheels, and specifically relates to a quick-release mechanism for a conveying wheel. Background Art

[0002] At present, the material conveying guide wheels of POT machines on the market usually have rubber rings sleeved on the surface of the conveying guide wheels to increase the transmission friction, and then are connected to the POT machine through a circular fixing mechanism. During the use of the conveying guide wheels, the rubber rings on their surfaces are prone to breakage and damage under the influence of temperature (heat generated by friction), resulting in a relatively high frequency of maintenance and replacement of the conveying guide wheels. Most of the existing conveying guide wheels and circular fixing mechanisms are designed as an integral structure to improve the connection stability. However, when replacing the conveying guide wheels, it is also necessary to replace the circular fixing mechanism in front of the axis together, increasing the cost. Content of the Utility Model

[0003] The purpose of the utility model is to provide a quick-release mechanism for a conveying wheel to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A quick-release mechanism for a conveying wheel, including a conveying guide wheel and a circular fixing seat. The conveying guide wheel is connected to the circular fixing seat through a quick-release mechanism. A through hole is opened at the axis position of the conveying guide wheel. The quick-release mechanism includes a connecting ring seat and a push rod. The connecting ring seat is installed at the bottom of the circular fixing seat. A ring groove corresponding to the connecting ring seat is provided at the top of the conveying guide wheel. A guiding groove is provided on the inner wall of the ring groove. One end of the push rod is slidably installed in the guiding groove, and the other end extends into the through hole. An insertion block is provided on the outer side of the end of the push rod located in the guiding groove. A slot corresponding to the insertion block is opened on the connecting ring seat. The push rod and the inner wall of the guiding groove are connected through an elastic member.

[0005] In the present application solution, the following improvement is made: A V-shaped groove is opened on the side of the conveying guide wheel, and a rubber ring is installed in the V-shaped groove.

[0006] In the present application solution, the following improvement is made: A through groove is opened on the conveying guide wheel. One end of the through groove communicates with the guiding groove, and the other end communicates with the through hole.

[0007] In the present application solution, the following improvement is made: The push rod is arranged in an L-shaped structure, which includes a horizontal part and a vertical part. The horizontal part is slidably installed in the through groove, and the vertical part is slidably installed in the guiding groove.

[0008] In the present application solution, the following improvement is made: One end of the elastic member is fixedly connected to the inner wall of the guiding groove, and the other end is fixedly connected to the vertical part of the push rod.

[0009] In the solution of this application, the following improvements are made. A through hole corresponding to and cooperating with the through hole is provided in the circular fixing base along the height direction, and a plurality of mounting holes communicating with the through hole are provided on the side of the circular fixing base.

[0010] Compared with the prior art, the utility model provides a quick-release mechanism for a transmission wheel, which has the following beneficial effects:

[0011] The utility model realizes the detachable connection between the transmission guide wheel and the circular fixing base through the quick-release mechanism. When replacing the transmission guide wheel, there is no need to disassemble and replace the whole mechanism, which effectively saves costs. At the same time, it avoids the situation that the installation position error caused by repeated installation of the transmission guide wheel may lead to product abnormality. During assembly, first push the push rod through the through hole, so that the horizontal part of the push rod moves inward along the through groove, thereby driving the vertical part to move along the guide groove towards the inner wall and extruding the elastic member. The vertical part drives the plug block to withdraw from the annular groove. Rotate the circular fixing base. While aligning the connecting ring seat with the annular groove, the slot also corresponds to the position of the guide groove. Insert the circular fixing base into the annular groove, release the push rod, and under the reaction force of the elastic member, the push rod drives the plug block to insert into the slot, realizing the locking of the connecting ring seat and the circular fixing base.

[0016] The following will describe the technical solutions in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model:

[0017] Such as Figures 1-3As shown in the figure, a quick-release mechanism for a transmission wheel is provided. The transmission guide wheel 1 is connected to the circular fixed seat 2 through the quick-release mechanism. A V-shaped groove 14 is provided on the side of the transmission guide wheel 1, and the angle of the V-shaped groove 14 is 90°. A rubber ring 5 is installed in the V-shaped groove 14. The quick-release mechanism mainly consists of a connecting ring seat 3 and a push rod 4. The connecting ring seat 3 is installed at the bottom of the circular fixed seat 2. A ring groove 12 corresponding to the connecting ring seat 3 is provided at the top of the transmission guide wheel 1. A guide groove 13 is provided on the inner wall of the ring groove 12. A through hole 11 is provided at the axial center position of the transmission guide wheel 1. At the same time, a through groove 15 is provided on the transmission guide wheel 1. One end of the through groove 15 communicates with the guide groove 13, and the other end communicates with the through hole 11. A through hole 21 corresponding to the through hole 11 is provided on the circular fixed seat 2 in the height direction. Two mounting holes 22 communicating with the through hole 21 are provided on the side of the circular fixed seat 2. The circular fixed seat 2 is connected and fixed to the POT machine table through the mounting holes 22. One end of the push rod 4 is slidably installed in the guide groove 13, and the other end extends into the through hole 11. An insertion block 41 is provided on the outer side of one end of the push rod 4 located in the guide groove 13. A slot 31 corresponding to the insertion block 41 is provided on the connecting ring seat 3. The push rod 4 is connected to the inner wall of the guide groove 13 through an elastic member 42, and the elastic member 42 can be a spring.

[0018] The push rod 4 is arranged in an L-shaped structure, which includes a horizontal part 43 and a vertical part 44. The horizontal part 43 is slidably installed in the through groove 15, and the vertical part 44 is slidably installed in the guide groove 13. One end of the elastic member 42 is fixedly connected to the inner wall of the guide groove 13, and the other end is fixedly connected to the vertical part 44 of the push rod 4.

[0019] Working principle: In the initial state, the end of the vertical part 44 of the push rod 4 extends out of the through groove 15 and is located in the through hole 11, and the insertion block 41 extends out of the guide groove 13 and is located in the ring groove 12. Push the push rod 4 from the through hole 11, so that the horizontal part 43 of the push rod 4 moves inward along the through groove 15, thereby driving the vertical part 44 to move towards the inner wall along the guide groove 13 and compress the spring. The vertical part 44 drives the insertion block 41 to withdraw from the ring groove 12. Rotate the circular fixed seat 2. While aligning the connecting ring seat 3 with the ring groove 11, the slot 31 also corresponds to the position of the guide groove 13. Insert the circular fixed seat 2 into the ring groove 11, release the push rod 4, and under the reaction force of the spring, the push rod 4 drives the insertion block 41 to insert into the slot 31 to realize the locking of the connecting ring seat 3 and the circular fixed seat 2. When disassembly is required, first push the push rod 4 to make the insertion block 41 disengage from the slot 31 to release the lock for replacement.
