Description

Technical Field

[0001] This utility model relates to the field of rubber cutting device technology, specifically to a high-efficiency rubber cutting device. Background Technology

[0002] The main function of the rubber cutting device is to cut, trim and process rubber materials according to certain specifications and requirements, ensuring that the size, shape and quality of rubber products meet the standards during the production process. The rubber cutting device can cut large pieces of rubber materials into small pieces or the required shape, which is convenient for subsequent processing or production. The rubber cutting device can greatly improve the efficiency of the cutting process, reduce manual intervention, increase the speed of the production line, reduce labor costs and improve overall production efficiency.

[0003] Chinese Patent Publication No. CN220660962U discloses a rubber cutting device, relating to the field of HIPS production technology. It includes a fixing mechanism and a cutting mechanism. The fixing mechanism includes an operating platform with a baffle plate inserted into the inner wall of one end of the platform. The cutting mechanism includes two adjusting screws, each with a fixing frame on its outer side. A second hydraulic cylinder is mounted on the top of each fixing frame, and a mounting plate is provided at the output end of each of the two second hydraulic cylinders. A cutting blade is mounted at the bottom center of the mounting plate. This invention uses the operation of the first hydraulic cylinder to move the baffle plate, thus blocking and limiting the rubber to be cut. The operation of the second hydraulic cylinder drives the cutting blade to cut the rubber. The adjusting screws can adjust the distance between the cutting blade and the baffle plate, allowing for convenient adjustment of the cut rubber size according to production needs, thereby improving HIPS production efficiency.

[0004] The aforementioned patent mentions that the rubber cutting device uses a second hydraulic cylinder to drive the cutting blade to move up and down, thereby cutting the rubber. However, during this process, there is no compression or restraint on both sides of the rubber material to be cut. Since rubber has a certain degree of softness and elasticity, when cutting, the cutting blade moves up and down to cut the rubber under high pressure without restraint, and the rubber material is prone to displacement or deformation, resulting in inaccurate cutting. Therefore, we propose a high-efficiency rubber cutting device. Utility Model Content

The first extrusion plate can adhere to both sides of the rubber material to be cut and perform extrusion and limiting, thereby solving the technical problem of insufficient cutting accuracy caused by the rubber material's tendency to shift or deform during high-pressure cutting operations.

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] See Figures 1-2 As shown, a high-efficiency rubber cutting device includes a main body 1, a support 11 on the main body 1, a rubber cutting blade assembly 12 on the support 11, and a limiting mechanism on the rubber cutting blade assembly 12 for pressing down on both sides of the rubber material to be cut. The limiting mechanism is equipped with an adjustment mechanism for gradually adjusting the extrusion force according to the thickness of the rubber material. The limiting mechanism includes a first extrusion plate 2, a displacement mechanism, a transmission mechanism, and a first guide mechanism. The first extrusion plate 2 is respectively disposed on both sides of the rubber cutting blade assembly 12 and is used to fit against both sides of the rubber material to be cut. The displacement mechanism is disposed on the first extrusion plate 2 and is used to drive the first extrusion plate 2 to move up and down. The transmission mechanism is disposed on the displacement mechanism and is used to provide working power to the displacement mechanism. The first guide mechanism is also disposed on the displacement mechanism and is used to assist the displacement mechanism in linear movement.

[0026] Specifically, the glue cutting tool assembly consists of a cylinder and a blade.

[0027] When the rubber cutting device performs rubber material cutting operations, the rubber material is first placed on the worktable of the main body 1 of the rubber cutting device, and then the cylinder of the rubber cutting blade assembly 12 is activated. The cylinder drives the blade to move downward. During this process, the rubber cutting blade assembly 12 transmits the downward moving force to the displacement mechanism through the transmission mechanism. The displacement mechanism is driven by the driving force, which drives the first extrusion plate 2 to move downward below the blade of the rubber cutting blade assembly 12.

[0028] The first extrusion plate 2 preferentially contacts and extrudes the rubber material, while the two first extrusion plates 2 respectively press down and limit the rubber material on both sides of the part to be cut. Through the limiting function of the first extrusion plates 2, it can be ensured that the rubber material to be cut maintains a fixed position during the cutting process, effectively avoiding material displacement or deformation, thereby reducing cutting errors caused by material loosening and deformation, and achieving a high degree of consistency in the shape of the rubber after cutting.

[0029] See Figures 1-5As shown, the displacement mechanism includes a connecting pipe 21 and a screw 22; the lower end of the connecting pipe 21 is connected to the first extrusion plate; the screw 22 is rotatably mounted on the cutting tool assembly 12, and the screw 22 is threadedly connected to the connecting pipe 21; the transmission mechanism includes a toothed plate 23, a toothed disc 24, and a bevel gear assembly; the toothed plate 23 is connected to the bracket 11; the toothed disc 24 is rotatably mounted on the cutting tool assembly 12, and the toothed disc 24 is mated with the toothed plate 23; the bevel gear assembly is rotatably mounted on the cutting tool assembly 12, with one working end of the bevel gear assembly connected to the toothed disc 24, and the other working end of the bevel gear assembly connected to... The screw 22 is connected; the bevel gear assembly includes a first bevel gear 25 and a second bevel gear 26; the first bevel gear 25 is rotatably mounted on the cutting tool assembly 12 and is connected to the screw 22; the second bevel gear 26 is rotatably mounted on the cutting tool assembly 12, the second bevel gear meshes with the first bevel gear, and the second bevel gear is connected to the gear disc 24; the first guide mechanism includes a slider 27 and a groove 28; the slider 27 is connected to the connecting pipe 21; the groove 28 is opened on the side of the cutting tool assembly 12 near the slider 27, and the groove 28 is used to cooperate with the slider 27 to move linearly.

[0030] Specifically, the rubber cutting tool assembly 12 has two screws 22 on one side, with the thread directions of the two screws 22 being opposite. The toothed plate 23 and the toothed disc 24 achieve meshing transmission, the first bevel gear 25 and the second bevel gear 26 mesh with each other, and the slider 27 and the slide groove 28 form a sliding pair.

[0031] When the rubber cutting tool assembly 12 moves downward, it drives the connected gear disk 24 to move downward synchronously. Under the action of the toothed plate 23, the gear disk 24 generates rotational motion during the downward movement. The rotation of the gear disk 24 is transmitted to the first bevel gear 25 through the second bevel gear 26. Due to the meshing relationship between the two bevel gear disks 24, the first bevel gear 25 rotates in the opposite direction following the second bevel gear 26, thereby driving the two screws 22 to rotate synchronously in the opposite direction.

[0032] The connecting tube 21 and the screw 22 are connected by a threaded pair. Because the threads of the two screws 22 are in opposite directions, the connecting tube 21 obtains stable linear motion when the screw 22 rotates, driving the first extrusion plate 2 to move downward. At the same time, the slider 27 on the connecting tube 21 slides synchronously along the groove 28. The precise fit between the slider 27 and the groove 28 effectively constrains the movement trajectory of the connecting tube 21, improving the connection rigidity and movement accuracy between the rubber cutting tool assembly 12 and the connecting tube 21.

[0033] When the first extrusion plate 2 moves down to contact the rubber material below the cutting tool assembly 12, the cutting tool assembly 12 continues to descend to complete the cutting action. At this time, the two first extrusion plates 2 apply uniform pressure to both sides of the rubber material to be cut, which can effectively suppress the elastic deformation of the rubber material during the cutting process, ensure uniform force on the cutting surface, and thus significantly reduce burrs, warping, and irregular deformation at the cutting edge. This effectively improves the dimensional accuracy and edge quality of the cut rubber product and increases cutting efficiency. At the same time, the material loss rate is reduced, achieving efficient utilization of the rubber material.

[0034] See Figures 1-6 As shown, the adjusting mechanism includes a second pressing plate 29, a second guiding mechanism, and an elastic reset member 210. The second pressing plate 29 is located below the first pressing plate 2. The second guiding mechanism is located between the first pressing plate 2 and the second pressing plate 29, and is used to assist the second pressing plate 29 in linear movement. The elastic reset member 210 is located on the second guiding mechanism and is rotatably mounted on the first pressing plate 2. The second guiding mechanism includes a fixed tube 211 and a sliding rod 212. The fixed tube 211 is located inside the elastic reset member 210 and is connected to the first pressing plate 2. The sliding rod 212 slides through the inner side of the fixed tube 211 and is threadedly connected to the second pressing plate 29. The upper end of the sliding rod 212 is connected to the upper end of the elastic reset member 210.

[0035] Specifically, a spring is selected as the implementing component for the elastic reset element. The inner diameter of the fixed tube 211 and the outer diameter of the slide rod 212 form a clearance fit.

[0036] When the first extrusion plate 2 moves downward to extrude the rubber material, the slide rod 212 slides upward along the fixed tube 211 under the reaction force of the rubber material. During this process, the slide rod 212 does not interfere with the limiting function of the first extrusion plate 2. When it is necessary to install the second extrusion plate 29 below the first extrusion plate 2, the slide rod 212 passes through the fixed tube 211 and is rotatably connected to the second extrusion plate 29 through a threaded pair, thereby constraining the second extrusion plate 29 below the first extrusion plate 2.

[0037] During the downward movement of the first extrusion plate 2, the second extrusion plate 29 first contacts the rubber material and applies pre-pressure. As the first extrusion plate 2 continues to move downward, the second extrusion plate 29 gradually approaches the first extrusion plate 2, while the slide rod 212 stretches the elastic reset member. This results in a gradual loading characteristic of the pressure on the rubber material, effectively avoiding the generation of impact loads. Through this two-stage extrusion mechanism, the internal stress concentration phenomenon of the material can be significantly reduced, and uneven deformation and material damage caused by excessive extrusion can be minimized.

[0038] Working principle: When the rubber cutting device performs rubber material cutting operations, the rubber material is first placed on the worktable of the main body 1 of the rubber cutting device. Then, the rubber cutting blade assembly 12 is started. When the cylinder drives the blade to move downward, the first extrusion plate 2 can move down to the bottom of the blade of the rubber cutting blade assembly 12 to contact the rubber material first and extrude it. This ensures that the rubber material to be cut maintains a fixed position during the cutting process, effectively avoiding material displacement or deformation. After the second extrusion plate 29 is installed, the pressure on the rubber material exhibits a progressive loading characteristic, effectively avoiding the generation of impact loads and reducing uneven deformation and material damage caused by excessive extrusion.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
