Description

[Technical field]

[0001] The invention relates to the field of rubber production devices, in particular to a rubber cutting device. [Background technology]

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce a large deformation under a small external force, and can return to its original shape after the external force is removed. In the production process of rubber, a cutting device is usually required to cut the rubber raw materials, and then mold them through a mold.

[0003] In the prior art, most rubber cutting devices include a workbench and a cutting knife, and the cutting knife is arranged on the workbench to reciprocate up and down. The rubber is placed on the workbench, and the rubber is cut by driving and controlling the cutting knife to move up and down. For example, patent application number: CN202221609781.0 discloses a rubber cutting device, including a cutting knife and a driving member for driving the cutting knife to move up and down, the cutting knife slides up and down and is installed on a frame, and the cutting knife is connected to the driving member. When the rubber raw material needs to be cut, the rubber raw material is placed on the frame, and the cutting knife is controlled to move up and down by the driving member to complete the cutting of the rubber. However, before the production of rubber products, it is first necessary to conduct random inspections on rubber hot liquid or rubber semi-finished test blocks to detect relevant parameters such as tensile strength and hardness. However, especially for semi-finished test blocks, the semi-finished test blocks have different shapes, such as sheet, rod, irregular block, etc. In order to cooperate with the detection, the semi-finished test blocks need to be cut into corresponding shapes, but such cutting devices cannot cut rubber blocks into any shape.

[0004] The present invention is proposed in view of the deficiencies in the prior art. [Summary of the invention]

[0005] The object of the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a rubber cutting device.

[0006] The present invention can be implemented by the following technical solutions:

[0007] The invention discloses a rubber cutting device, comprising a table and a shield, wherein a plurality of guide shafts are symmetrically fixed on both sides of the table, and guide wheels are arranged on the guide shafts, and the guide wheels are connected with each other by cutting ropes, and the cutting rope is driven to rotate by a cutting motor; a transverse screw rod and a transverse sliding rod are also transversely arranged above the table, and the transverse screw rod is driven to rotate by the transverse motor; a slide table is also arranged above the table, the transverse screw rod passes through the slide table and is threadedly connected to the slide table, the transverse sliding rod passes through the slide table and is slidably connected to the slide table, a longitudinal screw rod and a longitudinal sliding rod are also arranged above the slide table, the longitudinal screw rod is driven to rotate by the longitudinal motor, a slide plate is also arranged above the slide table, the longitudinal screw rod passes through the slide table and is threadedly connected to the slide table, the longitudinal sliding rod passes through the slide table and is slidably connected to the slide table, a rotating motor is also fixed on the slide table, a rotating disk is fixed on the output end of the rotating motor, a threaded pipe is also fixed on the slide plate above the rotating disk, a screw rod threadedly connected to the threaded pipe is arranged on the threaded pipe, and a pressing plate rotatably connected to the screw is arranged at the bottom of the screw rod. The rubber block to be cut is placed on the turntable and the screw is rotated. Since the screw is threadedly connected to the threaded pipe, when the screw rotates, the pressure plate moves close to the rubber block, and the pressure plate squeezes the rubber block and presses the rubber block onto the turntable. The transverse screw is driven to rotate by the transverse motor. Since the transverse screw passes through the slide and is threadedly connected to the slide, when the transverse screw rotates, the slide moves laterally and the rubber block moves laterally. The longitudinal screw is driven to rotate by the longitudinal motor. Since the longitudinal screw passes through the slide and is threadedly connected to the slide, when the longitudinal screw rotates, the slide moves longitudinally and the rubber block moves longitudinally, so that the rubber block can be moved laterally and longitudinally. The turntable is driven to rotate by the rotating motor. Since the pressure plate is rotatably connected to the screw, the rubber block can be rotated by rotating the turntable. The cutting rope is driven to rotate by the cutting motor. After the rubber block contacts the cutting rope, the rubber block is cut by contacting the cutting rope with the rubber block. The angle of the rubber block is adjusted by the rotating motor, and the rubber block can move laterally and longitudinally, so that the rubber block can be cut into any shape.

[0008] Preferably, a cutting shaft is fixed to the output end of the cutting motor, a cutting wheel is fixed to the cutting shaft, a mounting plate is also provided on the shield, a support rod is fixed to the mounting plate, the support rod passes through the shield and is slidably connected to the shield, a pressure rod is also fixed to the mounting plate, a pressure wheel is provided on the pressure rod, the cutting rope passes between the pressure wheel and the cutting wheel, and a spring is also fixed between the mounting plate and the shield. The mounting plate is pushed to move by the spring, the pressure wheel presses the cutting rope onto the cutting wheel, and the cutting motor drives the cutting wheel to rotate, so that the cutting rope can be moved quickly.

[0009] Preferably, a scraper is fixed under the table, and the cutting rope passes through the scraper and is slidably connected to the scraper. The cutting rope passes through the scraper and is slidably connected to the scraper, so that the rubber powder adhering to the cutting rope can be scraped off by the scraper.

[0010] Preferably, a water tank is fixed under the table, and the scraper is fixed in the water tank. The water tank is filled with tap water, the rubber powder is dispersed in the tap water, and the cutting rope is cooled by the tap water.

[0011] Preferably, a filter plate is fixed in the water tank, and the scraper is fixed on the filter plate.

[0012] Preferably, a fan is fixed on one side of the shield, and air holes are arranged on the other side of the shield at positions corresponding to the fan. The cutting rope reaches the fan position after passing through the water tank, and the airflow formed by the fan dries the cutting rope after passing through the cutting rope, so that the rubber block can be cut after the cutting rope is dried.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The cutting rope is driven to rotate by the cutting motor. After the rubber block contacts the cutting rope, the rubber block is cut by the cutting rope contacting the rubber block. The angle of the rubber block is adjusted by the rotating motor, and the rubber block can move horizontally and vertically, so the rubber block can be cut into any shape.
