A rubber product cutting mechanism

Abstract

This application relates to a rubber product cutting mechanism, including a base, a platform on the top of the base, and several cutting grooves on the top of the platform. A fixing frame is also provided on the top of the base at the edge of the platform, and several hydraulic cylinders are installed on the top of the fixing frame. This utility model drives a servo motor to rotate a lead screw, which drives a movable seat to slide along the mounting frame. This causes the support plates at both ends of the movable seat to move a pressing plate above the designated cutting groove. Combined with the cylinders driving the pressing plate to move downwards, the pressing plate is pressed against the cutting position of the rubber product. At the same time, the spring prevents the rubber product from being pressed too tightly, so that the rubber product remains stable during the cutting process and the cut end face remains flat.

Description

Technical Field

[0001] This application relates to the field of rubber product cutting technology, and in particular to a rubber product cutting mechanism. Background Technology

[0002] Rubber products refer to the activities of producing various rubber products using natural and synthetic rubber as raw materials, and also include rubber products produced from recycled waste rubber. During the processing of rubber products, cutting devices are usually used to cut and process the rubber products.

[0003] A search revealed that patent application number CN202422005603.2 discloses a cutting mechanism for processing rubber products, including a housing. A platform is fixedly connected to the inner bottom wall of the housing, and a stripping plate is fixedly connected to the inner top wall of the housing. An electric push rod is fixedly installed on the inner top wall of the housing, and a fixing plate is fixedly connected to the bottom end of the electric push rod. A blade is fixedly connected to the bottom of the fixing plate. This cutting mechanism for processing rubber products, through its housing, platform, cutting groove, stripping plate, electric push rod, fixing plate, and blade, facilitates stripping. It allows for quick and simple cutting of different parts of rubber products. If rubber adheres to the blade after cutting, the stripping plate can be used to remove the rubber as the blade rises, thus avoiding adhesion and improving processing efficiency, meeting user needs.

[0004] However, the cutting mechanism does not have a structure to fix the cutting position, which makes it impossible to guarantee the stability of the cutting end during cutting. This can easily lead to problems such as uneven and rough cutting ends, resulting in reduced cutting quality. In addition, the cutting blade will become dull quickly after prolonged use, and the cutting mechanism is not convenient for disassembling and replacing the cutting blade. Utility Model Content

This utility model is equipped with a fixing component and a cutting component. By rotating the threaded rod, the limiting pressure plate is driven to press and fix both ends of the rubber product, thereby improving the stability during cutting. By rotating the fixing screw in the corresponding fixing screw hole opened on the side wall of the fixing seat and the cutter holder, the cutter holder is moved out along the fixing groove opened on the fixing seat, thereby disassembling and replacing the cutting blade, making the operation more convenient.

[0016] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0017] This application discloses a rubber product cutting mechanism, including a base 1, a platform 2 on the top of the base 1, a plurality of cutting grooves 3 on the top of the platform 2, a clamping mechanism for limiting and pressing the edges of the cutting grooves 3 on the platform 2, symmetrical limiting components at both ends of the top of the platform 2, a fixing frame 4 on the top of the base 1 at the edge of the platform 2, a plurality of hydraulic cylinders 5 on the top of the fixing frame 4, and a cutting component connected to one end of each hydraulic cylinder 5.

[0018] refer to Figure 2 and Figure 3 The clamping mechanism includes a mounting frame 6 installed at the bottom of the platform 2. A lead screw 7 is installed inside the mounting frame 6. One end of the lead screw 7 is connected to a bearing seat on the inner wall of one end of the mounting frame 6. The other end of the lead screw 7 passes through a shaft hole opened in the side wall of one end of the platform 2 and is connected to a servo motor 8 fixed on the side wall. A movable seat 9 is fitted onto the lead screw 7 and is slidably installed inside the mounting frame 6. Sliding grooves are opened on both sides of the mounting frame 6. Symmetrical support plates 10 are provided at both ends of the movable seat 9. The support plates 10 are located away from the movable seat 9. One end of the cylinder 11 passes through the corresponding groove and is fixedly installed thereon. One end of the cylinder 11 passes through the through hole on the support plate 10 and is connected to the connecting rod 12. The other end of the connecting rod 12 is connected to the clamping plate 13. The clamping plate 13 is located on top of one of the cutting grooves 3 on the top of the shelf 2. The clamping plate 13 has a cutting opening that corresponds to the cutting groove 3. Springs 14 are connected to the bottom of both ends of the clamping plate 13. The springs 14 are looped around the outside of the connecting rod 12. The other end of the springs 14 is connected to the top of the support plate 10. Symmetrical guide rods 15 are also provided at both ends of the bottom of the 13. The other end of the guide rod 15 slides in the guide hole opened on the support plate 10. More specifically, the drive servo motor 8 drives the lead screw 7 to rotate, so that the movable seat 9 adapted on the lead screw 7 slides along the mounting frame 6. This allows the support plates 10 at both ends of the movable seat 9 to drive the pressing plate 13 to move above the designated cutting groove 3. Then, the cylinders 11 fixed at both ends of the support plate 10 are driven, so that the connecting rod 12 at one end drives the pressing plate 13 to move downward along the guide hole on the support plate 10 through the guide rods 15 at both ends. This allows the pressing plate 13 to press the rubber product at the cutting position, so that the rubber product remains stable during the cutting process and the cutting end face remains flat. At the same time, the springs 14 connected at both ends can prevent the rubber product from being pressed too tightly. If rubber adheres to the cutting blade 22 after cutting, the inner wall of the cutting opening of the pressing plate 13 can scrape off the adhered rubber during the upward movement of the cutting blade 22, thereby ensuring that the surface of the cutting blade 22 is clean and tidy, and avoiding affecting the cutting quality.

[0019] refer to Figure 2The limiting assembly includes symmetrical mounting brackets 16 installed at both ends of the top of the platform 2. Threaded rods 17 are fitted into threaded holes at the top of the mounting brackets 16. The other end of the threaded rods 17 is connected to a bearing seat on a limiting pressure plate 18 at the bottom of the mounting brackets 16. Symmetrical limiting rods 19 are provided at the top of both ends of the limiting pressure plate 18. The other end of the limiting rods 19 slides in the limiting holes on the mounting brackets 16. More specifically, by rotating the threaded rods 17 on the mounting brackets 16, the threaded rods 17 drive the limiting pressure plate 18 to move downwards along the upper limiting holes of the mounting brackets 16 through the limiting rods 19 at both ends. This allows the limiting pressure plate 18 to press and limit the ends of the rubber product, thereby improving stability and cutting quality during cutting.

[0020] refer to Figure 4 The cutting assembly includes a fixed base 20 connected to one end of a hydraulic cylinder 5. A blade holder 21 is installed in a fixed groove on the fixed base 20. A cutting blade 22 is installed at the bottom of the blade holder 21. The cutting blade 22 corresponds to the cutting groove 3 on the top of the platform 2. The blade holder 21 and the side wall of the fixed base 20 are also provided with corresponding fixing screw holes. A fixing screw 23 is provided inside the fixing screw hole. More specifically, by rotating the fixing screw 23 in the corresponding fixing screw hole on the side wall of the fixed base 20 and the blade holder 21, the blade holder 21 is moved out along the fixed groove on the fixed base 20, so that the cutting blade 22 can be disassembled, thereby improving the convenience of disassembling and replacing the cutting blade 22 for the operator.

[0021] The implementation principle of the rubber product cutting mechanism in this application embodiment is as follows: During use, the rubber product is placed on the platform 2. The threaded rod 17 on the mounting brackets 16 at both ends is rotated, causing the threaded rod 17 to drive the limiting pressure plate 18 to press and fix both ends of the rubber product. The servo motor 8 is driven, causing the lead screw 7 to rotate and drive the movable seat 9 to slide within the mounting frame 6. This causes the support plates 10 at both ends of the movable seat 9 to move the pressure plate 13 above the designated cutting groove 3. Then, the cylinder 11 is driven, causing one end connecting rod 12 to move the pressure plate 13 downwards to press the rubber product at the cutting position. Simultaneously, the springs 14 connected to the bottom of both ends prevent excessive pressure on the rubber product, ensuring proper cutting. To maintain stability and ensure the cutting end face remains flat, the hydraulic cylinder 5 at the top of the fixed frame 4 is driven, causing the fixed seat 20 connected at one end to drive the bottom cutting blade 22 to cut the rubber product. If rubber adheres to the cutting blade 22 after cutting, the inner wall of the cutting opening of the pressure plate 13 can scrape off the adhered rubber during the upward movement of the cutting blade 22, thereby ensuring that the surface of the cutting blade 22 is clean and tidy, and avoiding affecting the cutting quality. When the cutting blade 22 is replaced, the fixing screw 23 in the corresponding fixing screw hole opened on the side wall of the fixed seat 20 and the blade holder 21 is rotated, and the blade holder 21 is moved out along the fixing groove opened on the fixed seat 20, thereby disassembling and replacing the cutting blade 22, making the operation more convenient.

[0022] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
