Description

Technical Field

[0001] This utility model relates to the field of gasket production technology, specifically to a cutting device for rubber gasket production. Background Technology

[0002] Rubber gaskets possess properties such as oil resistance, acid and alkali resistance, and aging resistance. They can be directly cut into various shapes of sealing gaskets and are widely used in industries such as machinery, electronics, and chemicals. Rubber gaskets are typically made by punching from a single piece of rubber sheet. For mass production of gaskets of a specific specification, the rubber sheet is usually first cut into strip blanks, and then the blanks are processed into rubber gaskets of the corresponding shape and size using punching equipment. Currently, the cutting of rubber sheets is generally done manually by workers, which results in low efficiency. Utility Model Content

[0005] Preferably, a geared motor is installed at the bottom of the frame, which directly drives one of the feed rollers to rotate, and the two feed rollers are connected by a synchronous belt pulley assembly at their ends.

[0006] Preferably, two symmetrical gas springs connect the crossbar and the crossbeam.

[0007] Preferably, the vertical guide rail is slidably connected to an inverted V-shaped mounting bracket, and pressure rollers are respectively installed at both ends of the mounting bracket. The pressure rollers are located directly above the feed rollers, and a spring is provided on the top of the mounting bracket to apply a pushing force to them.

[0008] Preferably, a guide shoe is installed on the outer side of the vertical guide rail, and the guide shoe engages with the column and rolls along it.

[0009] Compared with the prior art, the beneficial effects of this utility model are: this utility model uses a feeding roller in conjunction with a pressure roller to realize automatic feeding of rubber sheet. During the feeding process, the cutter cuts the rubber sheet into strips and can adjust the width of the strips, which makes cutting convenient and helps to improve processing efficiency.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Please see Figure 1-2 This utility model provides a technical solution: a cutting device for rubber gasket production, including a frame 1 and a cutter 17. Two symmetrical columns 4 are fixedly installed on the upper middle part of the frame 1. A horizontal beam 5 is fixedly installed between the tops of the two columns 4. A downward-facing cylinder 6 is fixedly installed in the middle of the beam 5. Two parallel feeding rollers 2 are installed on the frame 1. The top of the feeding rollers 2 extends beyond the upper surface of the frame 1. The surface of the feeding rollers 2 is provided with knurling to increase friction. A reduction motor 3 is installed at the bottom of the frame 1. The reduction motor 3 directly drives one of the feeding rollers 2 to rotate. The central shafts at the ends of the two feeding rollers 2 are connected by a synchronous belt pulley assembly. A horizontal crossbar 8 is fixedly installed at the lower end of the cylinder 6. Two symmetrical air springs 7 are connected between the crossbar 8 and the beam 5. When the cylinder 6 is not working, the air springs 7 apply an upward elastic force to the crossbar 8 to prevent the cutter 17 from falling and inserting into the frame 1.

[0015] Vertical guide rails 9 are fixedly installed on the lower sides of both ends of the crossbar 8. A V-shaped mounting bracket 10 is slidably connected to the vertical guide rails 9. The vertical guide rail 9 consists of two parallel rectangular plates with vertical oblong holes b on each plate. A pin is fixedly connected to the mounting bracket 10, passing through the oblong holes b. Pressure rollers 11 are installed at both ends of the mounting bracket 10, positioned directly above the feed roller 2. A spring 15 is installed at the top of the mounting bracket 10 to apply thrust. Guide shoes 16 are installed on the outer side of the vertical guide rails 9. The guide shoes 16 engage with and roll along the column 4, constraining and guiding its vertical movement. A horizontal guide rail 12 is fixedly installed between the lower ends of the two vertical guide rails 9. Multiple sliders 14 are slidably connected in the horizontal guide rail 12. A cutter 17 is installed at the bottom of each slider 14. The horizontal guide rail 12 has multiple oval holes a along its length. A wing bolt 13 is screwed to the side of each slider 14. The wing bolt 13 passes through the oval hole a. By adjusting the position of the slider 14, the distance between two adjacent cutters 17 can be adjusted, thereby adjusting the width of the rubber sheet cut strip. The cutter 17 is located in the upper middle area of ​​the two feeding rollers 2.

[0016] Working principle: The cylinder 6 drives the pressure roller 11 and the cutter 17 to move up and down. When cutting, one end of the rubber plate is pressed between the feeding roller 2 and the pressure roller 11. When the cutter 17 moves down, it punctures the rubber plate. The feeding roller 2 rotates to feed the rubber plate to one side. The cutter 17 moves with the rubber plate to cut it into strips. The distance between adjacent cutters 17 can be adjusted by changing the position of the slider 14, so as to easily adjust the width of the rubber plate strips.

[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
