It is widely used in the manufacturing of tires, hoses, belts, seals, rubber gloves and other products, and plays an important role in industry, transportation, medical care and daily life.

[0003] Rubber production cutting equipment is a specialized piece of equipment used in rubber processing to cut rubber materials to preset sizes and shapes. It includes types such as longitudinal cutting mechanisms, transverse cutting knife sets, and ultrasonic cutting equipment, and plays an important role in the production of rubber products.

[0004] Patent application CN216181033U discloses a rubber cutting machine that prevents material jamming during rubber material transmission after positioning the rubber material between baffles, thereby improving the cutting efficiency of rubber material. Although the cutting machine can cut rubber, in actual use, it can only cut a section of rubber in one run and cannot cut rubber in segments, resulting in low working efficiency. Summary of the Invention

[0005] The purpose of this invention is to solve the problem of low rubber cutting efficiency in the prior art and to provide a cutting device for rubber production.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A cutting device for rubber production includes a worktable, a housing above the worktable, a slide rail connected inside the housing, a positioning rod rotatably connected to one end of the slide rail, and the upper end of the positioning rod penetrating the housing and connected to a motor fixed to the housing; multiple evenly arranged sliders are slidably connected inside the slide rail, and a connecting rod is connected to the middle of the lower surface of each slider; a short rotating rod is fixed to the outside of the positioning rod, a short rotating rod is rotatably connected to the outside of the connecting rod away from the positioning rod, and long and short rods are rotatably connected to the outside of the remaining positioning rods; adjacent short rotating rods and long rotating rods are rotatably connected to each other, as are adjacent long rotating rods; a mounting frame is connected to the lower end of both the connecting rod and the positioning rod, and a cutting blade is slidably connected inside the mounting frame.

[0008] Preferably, the slide rail and the housing are provided with movable grooves at the positions of the corresponding connecting rods.

[0009] Preferably, the length of the long rotating rod is twice that of the short rotating rod.

[0010] Preferably, the upper end of the cutting blade is connected to symmetrically arranged sliding plates, and the mounting bracket has symmetrically arranged sliding grooves corresponding to the positions of the sliding plates, with the sliding plates slidably connected in the sliding grooves.

[0011] Preferably, a housing is connected to the upper surface of one end of the mounting bracket, and a plug rod is slidably connected inside the housing. Slots are provided on both the mounting bracket and the cutting blade at the positions corresponding to the plug rods, and the plug rods are inserted into the slots.

[0012] Preferably, an outer ring is connected to the outside of the insertion rod, the outer ring is located inside the outer shell, a first spring is connected between the outer ring and the outer shell, and the upper end of the insertion rod passes through the outer shell and is connected to the pull plate.

[0013] Preferably, the mounting bracket is connected to symmetrically arranged external plates, and an L-shaped guard plate is slidably connected inside the external plates.

[0014] Preferably, multiple evenly arranged second springs are connected between the outer plate and the guard plate, and the lower end of the guard plate is lower than the lower end of the cutting blade.

[0015] Preferably, a support frame is connected to the upper surface of the workbench, and a cylinder is connected to the upper surface of the support frame. The output end of the cylinder passes through the support frame and is connected to the housing.

[0016] Preferably, the middle of both ends of the housing is connected to the limiting block, and the support frame is connected to the limiting block at the position of the limiting block, and the limiting rod is slidably connected inside the limiting block.

[0017] The beneficial effects of this utility model are:

[0018] 1) By starting the motor, the positioning rod is driven to rotate. The rotation of the positioning rod drives the short rotating rod connected to the positioning rod to rotate. Because the ends of the short rotating rod and the long rotating rod, as well as the ends of adjacent long rotating rods, are rotatably connected, the short rotating rod connected to the positioning rod will synchronously pull or push the long rotating rod and the short rotating rod rotatably connected to the connecting rod when it rotates. The long rotating rod and the short rotating rod rotatably connected to the connecting rod being pulled and pushed will drive the mounting bracket and the cutting blade to move, thereby adjusting the position of the cutting blade. Since the length of the long rotating rod is twice that of the short rotating rod, the distance between adjacent cutting blades can be kept constant when the position of the cutting blade is adjusted. The position of the cutting blade can be adjusted according to the required length of the rubber, improving adaptability. It can also cut multiple segments of rubber at the same time, improving the efficiency of rubber cutting.

[0019] 2) After adjusting the position of the cutting blade, place the rubber on the worktable at the position corresponding to the cutting blade. After placement, start the cylinder. The cylinder drives the cutting blade to descend. During the descent of the cutting blade, the guard plate will first contact the rubber, causing the guard plate to move upward and compress the second spring. The second spring will contract and store the restoring force when compressed. The restoring force acts on the rubber, which can compress the rubber. The cutting blade continues to descend to cut the rubber without causing the rubber to shift during the cutting process.

[0020] 3) When the cutting blade needs to be replaced, pull the pull plate upwards. The pull plate moves upwards, causing the insert rod to move out of the slot. After the insert rod is removed, the cutting blade is no longer fixed. The cutting blade can be removed from the mounting bracket to replace it with a new one. When replacing the cutting blade, pull the pull plate upwards again. The pull plate moves upwards, causing the insert rod and the outer connecting ring to move upwards, allowing the insert rod to enter the housing. The upward movement of the outer connecting ring compresses the first spring. The first spring will contract under compression and store restoring force. After the insert rod enters the housing, the cutting blade can be placed in the mounting bracket. When the slot of the cutting blade aligns with the insert rod, release the insert rod. Under the action of the restoring force of the first spring, the insert rod will reset, allowing the insert rod to be inserted into the slot and the cutting blade to be fixed. The installation and removal of the cutting blade is relatively simple and convenient, which can improve efficiency. Attached Figure Description

[0033] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0034] Please see Figure 1 - Figure 6 As shown, a cutting device for rubber production includes a workbench 1 for placing rubber.

[0035] A housing 2 is provided above the workbench 1. The housing 2 is used to provide the necessary space for the long rotating rod 26 and the short rotating rod 27 to move.

[0036] The housing 2 is connected to a slide rail 21, which is used to limit the position of the slider 23.

[0037] A positioning rod 22 is rotatably connected to one end of the slide rail 21. The positioning rod 22 is used to determine the position of one of the cutting blades 31, so that the other cutting blades 31 can adjust their positions with this as the target.

[0038] Multiple evenly arranged sliders 23 are slidably connected inside the slide rail 21. Through the cooperation between the sliders 23 and the slide rail 21, the cutting blade 31 can be prevented from deflecting or shifting when adjusting its position.

[0039] Each slider 23 has a connecting rod 24 connected to the middle of its lower surface. The connecting rod 24 is used to adjust the position of the cutting blade 31.

[0040] The slide rail 21 and the housing 2 are provided with movable grooves 25 at the positions corresponding to the connecting rod 24. The movable grooves 25 are used to provide the necessary movement space for the connecting rod 24.

[0041] A short rotating rod 27 is fixed to the outside of the positioning rod 22, and a short rotating rod 27 is rotatably connected to the outside of the connecting rod 24 away from the positioning rod 22. The length of the long rotating rod 26 is twice that of the short rotating rod 27. With this arrangement, the distance between the cutting blades 31 can be kept constant when adjusting the position of the cutting blades 31.

[0042] The remaining positioning rods 22 are rotatably connected to long and short rods on their outer sides. The ends of adjacent short rotating rods 27 and long rotating rods 26, as well as the ends of adjacent long rotating rods 26, are rotatably connected. With this arrangement, the position of the cutting blade 31 can be adjusted synchronously.

[0043] The upper end of the positioning rod 22 passes through the housing 2 and is connected to the motor 28 fixed on the housing 2. The motor 28 is used to drive the positioning rod 22 to rotate.

[0044] Both the lower ends of the connecting rod 24 and the positioning rod 22 are connected to the mounting bracket 3. A cutting blade 31 is slidably connected inside the mounting bracket 3. The mounting bracket 3 is used to fix the position of the cutting blade 31, and the cutting blade 31 is used to cut the rubber.

[0045] The upper end of the cutting blade 31 is connected to a symmetrically arranged sliding plate 32. The mounting bracket 3 has symmetrically arranged sliding grooves 33 corresponding to the position of the sliding plate 32. The sliding plate 32 is slidably connected in the sliding groove 33. The sliding plate 32 and the sliding groove 33 cooperate to initially position the cutting blade 31.

[0046] The mounting bracket 3 has a housing 34 connected to the upper surface of one end. A rod 35 is slidably connected inside the housing 34. The mounting bracket 3 and the cutting blade 31 are provided with slots 36 corresponding to the positions of the rod 35. The rod 35 is inserted into the slot 36. The rod 35 and the slot 36 cooperate to position the cutting blade 31 and prevent the cutting blade 31 from moving.

[0047] An outer ring 37 is connected to the outside of the insertion rod 35. The outer ring 37 is located inside the outer casing 34. A first spring 38 is connected between the outer ring 37 and the outer casing 34. The first spring 38 works with the outer ring 37 to reset the insertion rod 35.

[0048] The upper end of the insertion rod 35 passes through the outer casing 34 and is connected to the pull plate 39, which is used to pull the insertion rod 35 out of the slot 36.

[0049] The mounting bracket 3 is connected to symmetrically arranged outer plates 4. An L-shaped guard plate 41 is slidably connected inside the outer plate 4. The outer plate 4 is used to limit the position of the guard plate 41. The guard plate 41 is used to block the cutting blade 31, protect the workers, and at the same time, it can press the rubber tightly and fix it when cutting the rubber.

[0050] The lower end of the guard plate 41 is lower than the lower end of the cutting blade 31. This arrangement ensures that the cutting blade 31 is positioned between the two guard plates 41 when it is not in operation.

[0051] A plurality of evenly arranged second springs 42 are connected between the outer plate 4 and the protective plate 41. The second springs 42 are used to reset the protective plate 41.

[0052] A support frame 51 is connected to the upper surface of the workbench 1. A cylinder 5 is connected to the upper surface of the support frame 51. The output end of the cylinder 5 passes through the support frame 51 and is connected to the housing 2. The support frame 51 is used to install and fix the cylinder 5. The cylinder 5 is used to drive the housing 2 to rise and fall, so that the cutting blade 31 rises and falls.

[0053] Both ends of the housing 2 are connected to the middle of the limiting block 52. The support frame 51 is connected to the limiting rod 53 at the position corresponding to the limiting block 52. The limiting rod 53 is slidably connected in the limiting block 52. Through the cooperation of the limiting rod 53 and the limiting block 52, the position of the housing 2 can be limited.

[0054] Working principle:

[0055] By starting the motor 28, the positioning rod 22 is rotated. The rotation of the positioning rod 22 causes the short rotating rod 27 connected to the positioning rod 22 to rotate. Since the short rotating rod 27 is rotatably connected to the end of the long rotating rod 26 and to the end of the adjacent long rotating rod 26, the short rotating rod 27 connected to the positioning rod 22 will synchronously pull or push the long rotating rod 26 and the short rotating rod 27 rotatably connected to the connecting rod 24 when it rotates. The long rotating rod 26 and the short rotating rod 27 rotatably connected to the connecting rod 24 will be pulled and pushed, which will drive the mounting bracket 3 and the cutting blade 31 to move. This allows the position of the cutting blade 31 to be adjusted. Since the length of the long rotating rod 26 is twice that of the short rotating rod 27, the distance between adjacent cutting blades 31 can remain constant when the position of the cutting blade 31 is adjusted. The position of the cutting blade 31 can be adjusted according to the required length of the rubber, improving adaptability. It can also cut the rubber in multiple segments at the same time, improving the efficiency of rubber cutting.

[0056] After the position of the cutting blade 31 is adjusted, the rubber is placed on the worktable 1 at the position corresponding to the cutting blade 31. After placement, the cylinder 5 is started. The cylinder 5 drives the cutting blade 31 to descend. During the descent of the cutting blade 31, the guard plate 41 will first contact the rubber, causing the guard plate 41 to move upward and compress the second spring 42. The second spring 42 will contract and store the restoring force when compressed. The restoring force acts on the rubber, which can compress the rubber. The cutting blade 31 continues to descend to cut the rubber without causing the rubber to shift during the cutting process.

[0057] When the cutting blade 31 needs to be replaced, pull the pull plate 39 upwards. The pull plate 39 moves upwards, causing the insertion rod 35 to move out of the slot 36. After the insertion rod 35 moves out, the cutting blade 31 is no longer fixed, and the cutting blade 31 can be removed from the mounting bracket 3 for replacement with a new cutting blade 31. When replacing the cutting blade 31, pull the pull plate 39 upwards again. The pull plate 39 moves upwards, causing the insertion rod 35 and the outer connecting ring 37 to move upwards, allowing the insertion rod 35 to enter the housing 34. The outer ring 37 moves upwards, affecting the first spring. When spring 38 is compressed, the first spring 38 will contract and store restoring force. After the insertion rod 35 enters the housing 34, the cutting blade 31 can be placed into the mounting bracket 3. When the slot 36 of the cutting blade 31 corresponds to the insertion rod 35, the insertion rod 35 is released. Under the action of the restoring force of the first spring 38, the insertion rod 35 will return to its original position, allowing the insertion rod 35 to be inserted into the slot 36, thus fixing the cutting blade 31. The installation and removal of the cutting blade 31 is relatively simple and convenient, which can improve efficiency.
