Technical Field

[0001] This utility model belongs to the technical field of rubber cutting equipment for rubber parts processing, specifically, it relates to a rubber cutting machine for rubber parts processing. Background Technology

[0002] Rubber parts are various components made of rubber materials, widely used in the automotive, machinery, electronics, construction, and medical industries. Rubber possesses excellent elasticity, wear resistance, corrosion resistance, and high-temperature resistance. Common rubber parts include seals, rubber strips, shock absorbers, hoses, and rubber gaskets. Through special processing techniques, such as molding, extrusion, and cutting, rubber parts can be produced in various shapes, sizes, and performance characteristics to meet diverse needs.

[0003] A rubber cutting machine is a specialized piece of equipment used for cutting and processing rubber materials, and is widely used in the production of rubber products. This equipment, through precise cutting tools and a control system, achieves accurate, length-based, or shape-based cutting of rubber parts, ensuring that the product's dimensions and shape meet requirements.

[0004] Patent CN219633872U discloses a rubber cutting device for processing ethylene propylene rubber, including a rubber cutting mechanism and a lifting component. The device compresses the rubber strip to prevent it from being stretched and deformed during cutting, which would cause the cut to be tilted and uneven. It also cleans the two sides of the blade by setting a shovel plate to reduce the sticky substances that may adhere to the blade and make it less sharp, thereby increasing the service life of the blade.

[0005] However, in the technical solution described in the above patent, during the processing and cutting of rubber strips, due to the differences in rubber materials (such as soft rubber, hard rubber, and composite rubber containing fibers or metals), if the appropriate matching blade is not changed according to the characteristics of different materials during the cutting process, it may lead to uneven cutting, low precision, or even damage to the blade or rubber part itself because the blade is not suitable for the type of rubber being processed. Utility Model Content

[0006] This utility model provides a rubber cutting machine for processing rubber parts, in order to solve the technical problem that the cutting effect is poor or even the blade or rubber part itself is damaged due to the failure to change the appropriate blade according to the characteristics of different materials during the cutting process.

[0027] Please see Figures 1-3As shown, a rubber cutting machine for processing rubber parts includes a conveyor frame 1 with a U-shaped cross-section; multiple drive shafts 2 are arranged laterally inside the conveyor frame 1, and the rotating shafts are rotatably connected to the conveyor frame 1; a conveyor belt 3 is arranged on the multiple rotating shafts, which is used to transport rubber parts 6 and assist in cutting the rubber parts 6; rubber parts 6 are placed on the conveyor belt 3; and support legs 4 are fixed at the four corners of the bottom of the conveyor frame 1.

[0028] Two frames 5 are symmetrically arranged on both sides of the conveyor frame 1 near the center, and the height of the frames 5 is higher than that of the conveyor frame 1. Each frame 5 has a sliding groove 51 with an open top. A bearing seat 8 is slidably arranged in the sliding groove 51. Each frame 5 has a groove 52 at the bottom. A cylinder 7 is fixedly arranged inside the groove 52, and the output end of the cylinder 7 passes through the sliding groove 51 and is fixedly connected to the bearing seat 8.

[0029] Please see Figure 1 , Figure 4 as well as Figure 5 As shown, a rotating shaft 19 is also provided in the sliding groove 51 of the two frames 5, and the two ends of the rotating shaft 19 are fixedly connected to the inner rings of the two bearing seats 8 respectively; a rotating drum 16 is connected to the rotating shaft 19 at a position key corresponding to the top of the conveyor belt 3. The rotating drum 16 can move axially on the rotating shaft 19, but cannot rotate circumferentially with the rotating shaft 19; a plurality of second dovetail grooves 17 in a circular array are provided on the rotating drum 16 (six are provided in this embodiment), and one end of the second dovetail groove 17 is open and the other end is closed; a matching tool holder 14 is provided in each of the second dovetail grooves 17; as Figure 5 As shown, a first cutter 11, a second cutter 12, and a third cutter 13 are fixedly connected to each pair of adjacent cutter holders 14; a limiting groove 18 is also provided at the end position of the rotating cylinder 16 corresponding to the opening end of the second dovetail groove 17, and the cross-section of the limiting groove 18 is T-shaped; a fitting limiting block 15 is rotatably connected inside the limiting groove 18; a fixedly connected circular block 9 is provided at the outer end of the limiting block 15; a first dovetail groove 10 corresponding to the second dovetail groove 17 is provided on the outer edge of the circular block 9.

[0030] One of the cylinders 7 has a horizontally arranged fixing plate 20 fixed to the position inside the slide groove 51 at the output end; a stepper motor 22 is fixedly placed on the fixing plate 20 via a fixing ring 21; the output end of the stepper motor 22 is connected to the rotating shaft 19 via a flange 23.

[0031] To facilitate understanding of the above-mentioned technical solution of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below:

[0032] The operator first places the rubber part 6 on the conveyor belt 3 and starts the cylinder 7. Since the output end of the cylinder 7 is connected to the bearing seat 8 in the slide 51, and the inner ring of the bearing seat 8 is connected to the rotating shaft 19, when the output end of the cylinder 7 outputs vertically, the rotating shaft 19 can be driven to move up and down in the slide 51 through the bearing seat 8. Since the rotating shaft 19 is keyed to the rotating drum 16, and two first cutters 11, two second cutters 12, and two third cutters 13 are respectively arranged on the circumference of the rotating drum 16, the first cutters 11, second cutters 12, and third cutters 13 will also move up and down during the uniform output of the cylinder 7. The rubber part 6 can be cut by using the bottom first cutter 11, second cutter 12, or third cutter 13.

[0033] The first cutter 11 is a sharp and thin stainless steel or coated blade, mainly designed for rubber parts 6 made of soft rubber; the second cutter 12 is a carbide or high-carbon steel blade, mainly designed for rubber parts 6 made of hard rubber; and the third cutter 13 is a toothed or specially coated blade, mainly designed for composite rubber containing fibers / metals. By setting different cutters to adapt to the cutting of different rubber parts 6, the cutting quality, cutting accuracy and service life of the blades can be improved.

[0034] During operation, for rubber parts 6 of different materials, the operator can control the stepper motor 22 to drive the drum 16 to rotate stepwise. The rotation of the drum 16 causes the cutter position to change. By precisely controlling the forward and reverse rotation of the stepper motor 22, the cutter can be accurately positioned. The operator can easily switch to the first cutter 11, the second cutter 12, or the third cutter 13. According to the specific material of the rubber parts 6 on the conveyor belt 3, the type of cutter can be flexibly adjusted, and then the cutting operation can be performed. This is convenient and efficient, and can handle various cutting tasks, significantly improving work efficiency.

[0035] Furthermore, if one of the first cutter 11, the second cutter 12, or the third cutter 13 is damaged, the operator can promptly start the stepper motor 22 to rotate the drum 16 to the position of another spare first cutter 11, the second cutter 12, or the third cutter 13. The spare first cutter 11, the second cutter 12, or the third cutter 13 can then be used to continue cutting the rubber part 6, thereby ensuring the continuous operation of the production line, avoiding downtime caused by blade damage, and greatly improving production efficiency.

[0036] In addition, the rotating drum 16 of this invention has multiple circumferentially arrayed second dovetail grooves 17. A limiting groove 18 is also provided at the end of the rotating drum 16 corresponding to the opening of the second dovetail groove 17. A matching limiting block 15 is rotatably connected within the limiting groove 18. A fixedly connected circular block 9 is provided at the outer end of the limiting block 15. A first dovetail groove 10, corresponding one-to-one with the second dovetail groove 17, is provided on the outer edge of the circular block 9. During routine maintenance and repair, the operator can rotate the circular block 9 to align the first dovetail groove 10 with the second dovetail groove 17, facilitating the removal of the first cutter 11, second cutter 12, or third cutter 13 that needs to be replaced or disassembled for repair. After replacement, the operator can rotate the circular block 9 again to misalign the first dovetail groove 10 with the second dovetail groove 17, thereby preventing the first cutter 11, second cutter 12, or third cutter 13 from falling off the rotating drum 16.
