Description

Technical Field

[0001] The utility model belongs to the technical field of rubber processing, and in particular relates to a cutting device for rubber processing. Background Art

[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 very small external force. It can return to its original shape after the external force is removed. Rubber products are widely used in various aspects of industry or life. In the process of processing rubber, rubber needs to be cut.

[0003] The patent application with publication number CN215093759U discloses a cutting device for processing rubber products, including a base, a base top platform is fixedly installed on the top of the base, a base top platform side groove is provided on one side of the base, a side movable platform is movably installed on one side of the base, a fixing rod is fixedly installed on the top of the side movable platform, one end of the fixing rod extends to the surface of the base top platform, and a fixing rod bottom plate is fixedly installed on the bottom end of the fixing rod. The utility model reduces the wear on the surface of the bottom plate side buckle when the bottom plate side buckle moves inside the top platform side groove through the cooperation of the pulley and the ball, thereby increasing its service life. Through the cooperation of the spring and the spring buckle, the ball can move inside the ball groove, thereby reducing the wear of the ball evenly, preventing the outer side of the ball from being severely worn, which reduces the function of the ball and causes the ball to lose the function of reducing wear.

[0004] The above patent increases the service life of the device by allowing the side buckles of the bottom plate to move inside the side grooves of the top platform. Since rubber is a soft product, the above patent does not have a fixed structure, which causes the rubber to easily shift in position during cutting, thereby reducing the quality of rubber cutting. In addition, the cut rubber will pop out due to its own elasticity, and the popped-out rubber needs to be collected manually, thereby reducing the efficiency of rubber cutting.

[0005] In summary, the utility model provides a cutting device for rubber processing to solve the above problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a cutting device for rubber processing, which has the advantages that the clamping block is driven to descend by rotating the gear, thereby fixing the rubber to be cut, preventing the rubber from being displaced during cutting and causing damage to the rubber product, making the cutting more precise and improving the cutting efficiency. The rubber can be cut by rotating the first threaded rod. The operation is simple and the staff does not need to hold the rubber for cutting, which can effectively ensure the safety of the staff. After the rubber cutting is completed, the waste generated during the rubber cutting enters the waste box through the inclined plate, which facilitates the cleaning and recycling of the waste.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A cutting device for rubber processing, comprising: a cutting table, two symmetrical rectangular shells are fixed on both sides of the upper part of the cutting table, openings are opened on the opposite sides of the two rectangular shells, first bearings are installed at both ends of the inner part of the rectangular shells, a first threaded rod is rotatably connected between the first bearings, a transmission assembly is installed at one end of the two first threaded rods, a first motor is installed at one end of the rectangular shell away from the transmission assembly, a slider is fixed on the circumference of the first threaded rod, a connecting plate is fixed on one side of the slider close to the middle of the cutting table, an inverted U-shaped plate is fixed on the upper part of the two connecting plates, and a fixing assembly is installed on the upper part of the inverted U-shaped plate;

[0009] A notch is provided at one end of the cutting table away from the transmission assembly, and a cutting assembly is arranged in the notch.

[0010] By adopting the above technical solution, the rubber can be fixed by rotating the fixing component on the upper part of the inverted U-shaped plate to make the fixing component move downward, thereby preventing the rubber from being displaced during the cutting process, thereby reducing the cutting quality of the rubber. Then, the first motor can be started to drive the two first threaded rods to rotate synchronously under the action of the transmission component. The operation is simple, and the machine replaces manual labor, which improves the cutting efficiency while effectively ensuring the safety of the staff. The synchronous rotation of the two first threaded rods drives the movement of the slider, and the movement of the slider drives the movement of the connecting plate, thereby driving the fixed rubber to move in the direction of the cutting component, so that the cutting component cuts the rubber. The operation is simple. The design of the first bearing reduces the friction between the first threaded rod and the rectangular shell, thereby improving the rotation efficiency of the first threaded rod. The design of the first motor can make the two first threaded rods rotate synchronously, thereby reducing the cost of the device. Because the rubber itself has a large friction force, the design of the connecting plate avoids the friction between the rubber and the cutting table during movement, thereby improving the efficiency of rubber cutting.

[0011] The utility model is further configured as follows: the transmission assembly includes a second bearing installed at one end of the first threaded rod, the second bearing is installed on the outside of the rectangular shell, a transmission wheel is installed at the center of the second bearing, a belt is connected for transmission between the two transmission wheels, one end of the first threaded rod is fixedly connected to the output shaft of the first motor, and the first threaded rod is fixedly connected to the transmission wheel.

[0012] By adopting the above technical solution, by rotating a first threaded rod, the transmission wheel is driven to rotate, and the rotation of the transmission wheel drives the rotation of another first threaded rod under the action of the belt, thereby causing the two first threaded rods to rotate synchronously, and then driving the rubber to move in the direction of the cutting assembly. The design of the belt can simultaneously enable the two first threaded rods to rotate synchronously, and the operation is simple. The design of the second bearing can reduce the friction between the rectangular shell and the transmission wheel, thereby improving the transmission efficiency of the transmission wheel.

[0013] The utility model is further configured as follows: the fixing assembly includes two groups of symmetrical pressing mechanisms, and the two groups of pressing mechanisms are located at the upper parts of the two connecting plates, the pressing mechanism includes a second threaded rod threadedly connected to the middle part of the inverted U-shaped plate, a gear is fixed to the upper part of the second threaded rod located at the upper part of the inverted U-shaped plate, and the two gears of the two groups of pressing mechanisms are meshed, a handle is fixed to the upper part of one of the gears, two sliding rods are slidingly matched inside the inverted U-shaped plate, the two sliding rods are symmetrical about the second threaded rod, a clamping plate is fixed to the bottom of the second sliding rod located at the lower side of the inverted U-shaped plate, and the clamping plate is rotatably connected to the second threaded rod.

[0014] By adopting the above technical solution, by placing the rubber on the upper part of the connecting plate, the two gears are meshed, and the handle is rotated. The rotation of the handle drives the synchronous rotation of the two gears, thereby driving the second threaded rod to move downward. The downward movement of the second threaded rod drives the downward movement of the clamping plate, so that the clamping plate fixes the rubber. The design of the fixing component allows the rubber to maintain linear motion during the process of moving toward the cutting component, so that the rubber can be cut more smoothly and accurately. The design of the two sets of sliding rods makes the clamping plate more stable during the downward pressing process, and the sliding rods can increase the fixation of the clamping plate to the rubber.

[0015] The utility model is further configured as follows: the cutting assembly includes an inclined plate fixed at the bottom of one end of the slot, a rectangular slot is opened in the middle of the inclined plate, a rotating shaft is rotatably fitted in the rectangular slot, a cutting knife is fixed on the circumferential side of the middle of the rotating shaft, a second motor is installed on one side of the inclined plate, and the output shaft of the second motor is fixedly connected to one end of the rotating shaft.

[0016] By adopting the above technical solution, the cutting knife can be driven to cut the rubber by starting the second motor. The structure is simple, and the inclined plate and the cutting table are inclined at a certain angle, so that a gap is left between the inclined plate and the cutting table.

[0017] The utility model is further configured as follows: support columns are fixed at four corners of the bottom of the cutting table, and cushion blocks are installed at the bottoms of the support columns.

[0018] By adopting the above technical solution, the design of the support column can support the fixed cutting table, which is convenient for the staff to operate. The pad is made of rubber material, which increases the friction between the support column and the ground, thereby reducing the displacement of the cutting table during operation, which leads to inaccuracy in rubber cutting.

[0019] The utility model is further configured as follows: a waste box is installed at the bottom of the cutting assembly, the upper part of the waste box is fixed to the bottom of the cutting table, a box door is installed on the side of the waste box away from the transmission assembly, and a handle is installed on the outer side of the box door.

[0020] By adopting the above technical solution, when the rubber cutting is completed, the waste or debris can be put into the waste box through the gap between the inclined plate and the cutting table, so that the operating table is clean and convenient for the cutting table to carry out the next round of work. The design of the handle and the box door enables the staff to handle the waste or debris in the waste box quickly and conveniently, and the operation is simple.

[0021] The utility model is further configured as follows: a baffle is fixed on the upper part of one end of the cutting table away from the transmission assembly.

[0022] By adopting the above technical solution, the design of the baffle can block the waste or debris generated during the cutting process of the rubber, effectively preventing the waste or debris from collapsing.

[0023] In summary, the beneficial technical effects of the utility model are:

[0024] 1. The clamping block is driven to descend by rotating the gear, so as to fix the rubber to be cut, and prevent the rubber from displacement during cutting, which may cause damage to the rubber product, making the cutting more accurate and improving the cutting efficiency. The rubber can be cut by rotating the first threaded rod. The operation is simple and the staff does not need to hold the rubber for cutting, which can effectively ensure the safety of the staff.

[0025] 2. After the rubber cutting is completed, the waste or debris can be put into the waste box through the gap between the inclined plate and the cutting table, so that the operating table is clean and convenient for the cutting table to carry out the next round of work. The design of the handle and the box door allows the staff to handle the waste or debris in the waste box conveniently and quickly, and the operation is simple.
