Description

Technical Field

[0001] The utility model relates to the technical field of rubber cutting machines, in particular to an automatic rubber cutting machine. 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 small external force. It can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer. After processing, it is made into a material with elasticity, insulation, impermeability to water and air. It is a highly elastic polymer compound. Rubber products are widely used in industry and life.

[0003] The raw material of rubber cannot be used directly. It is processed into relatively large blocks during transportation. Not so much is needed during production and processing. Therefore, the raw material needs to be processed and cut into pieces. The existing rubber cutting machine has nothing to press the rubber when the knife cuts the rubber, which makes the surface of the rubber cutting uneven, and the length of the rubber blocks is different. There will be residual rubber on the knife after cutting. If it is not cleaned in time, it will also affect the flatness of the subsequent rubber cutting surface. Utility Model Content

[0025] Example 1

[0026] An automatic rubber cutting machine includes a workbench 1 and a mounting frame 2 mounted on the workbench 1. A driving member 3 is fixedly connected to the top of the mounting frame 2. The driving end of the driving member 3 passes through the mounting frame 2 and is connected to a cutter 4 arranged in a vertical direction. A clamping assembly is arranged on the cutter 4. A limit assembly for limiting the length of raw material feeding is arranged on the side of the mounting frame 2 away from the clamping assembly. The limit assembly can abut against the cutter 4. A cleaning roller 22 parallel to the cutter 4 is rotatably connected to the lower part of the mounting frame 2. A plurality of cleaning bristles 23 are arranged on the outer wall of the cleaning roller 22. The cleaning bristles 23 are in contact with the surface of the cutter 4. The mounting frame 2 is located in the middle of the workbench 1. Vertical slide grooves are arranged on the opposite side walls of the mounting frame 2. The two ends of the cutter 4 are respectively placed in the slide grooves and move up and down along the height direction of the slide grooves. A cutting groove 11 is provided at the place where the workbench 1 and the cutter 4 are opposite. The cutter 4 can extend into the cutting groove 11. The driving member 3 is a hydraulic cylinder. When the hydraulic cylinder is started, the piston rod of the hydraulic cylinder moves up and down, driving the cutter 4 to move up and down, thereby realizing the cutting of the rubber. When cutting, the rubber is first pressed and fixed by the clamping assembly, and then the cutter 4 cuts the rubber, so that the movement of the rubber can be prevented from affecting the flatness of the cut surface of the rubber. At the same time, the rubber feed length is adjusted by the limit assembly, so that the length of the rubber block after cutting can be consistent. The residual glue on the surface of the cutter 4 can be cleaned in time by the cooperation of the cleaning roller 22 and the cleaning bristles 23, so that the residual glue can be prevented from affecting the flatness of the cut surface of the rubber block. The cooperation of the clamping assembly, the limit assembly and the cleaning bristles 23 can cut rubber blocks with a flat surface and the same length, which is convenient for the subsequent processing of the rubber blocks.

[0027] In this embodiment, the clamping assembly includes a first connecting rod 7 arranged vertically, a first spring 8 is sleeved on the first connecting rod 7, a pressing plate 9 is connected to the bottom of the first spring 8, a first sliding block 6 is connected to the top of the first spring 8, and the first sliding block 6 is fixedly connected to the cutter 4 through a connecting seat 5. The connecting seat 5 can be welded to the cutter 4, or can be detachably connected to the cutter 4 by screws. When in use, the hydraulic cylinder drives the cutter 4 to move downward, the cutter 4 drives the first sliding block 6 to move downward, the first sliding block 6 drives the first spring 8 to move downward, and the first spring 8 drives the pressing plate 9 to move downward. When the pressing plate 9 contacts the rubber material, the cutter 4 continues to move downward, so that the first sliding block 6 moves downward to compress the first spring 8 so that the pressing plate 9 is pressed against the rubber material. When the cutter 4 contacts the rubber material, the pressing plate 9 has fixed the rubber material, thereby preventing it from moving when the cutter 4 cuts the rubber material. It can fix the rubber material while cutting the material, which is conducive to improving the cutting speed and cutting quality.

[0028] In this embodiment, a plurality of spherical protrusions 24 are provided at the bottom of the pressing plate 9. This facilitates fixing of the rubber material with an uneven surface and improves the stability of the fixing of the rubber material.

[0029] In this embodiment, the limiting assembly includes a second connecting rod 14 arranged horizontally, one end of the second connecting rod 14 is fixedly connected to the mounting frame 2, the other end of the second connecting rod 14 is sleeved with a second sliding block 15 and a second spring 16 in sequence, a fixing plate 17 is installed on the second sliding block 15, a fixing block 18 is installed on the fixing plate 17, a horizontally arranged adjusting rod 19 is installed on the fixing block 18, and a side of the fixing plate 17 close to the cutter 4 is fixedly connected to a limiting plate 20. The limiting plate 20 is detachably connected to the fixing plate 17 through an L-shaped angle steel, specifically, detachably connected through screws. Under normal circumstances, the second spring 16 remains in its original state, and the limit plate 20 is located in front of the rubber material feeding and is spaced a certain distance from the cutting groove 11. After the rubber material is fed, it contacts the limit plate 20 to limit the rubber material feeding. When cutting, when the cutter 4 is lowered to contact the rubber material, the pressure plate 9 fixes the rubber material, and the adjustment rod 19 is pressed against the cutter 4, so that the adjustment rod 19 moves away from the cutter 4 (the second spring 16 is compressed at this time), and at the same time, the adjustment rod 19 drives the limit plate 20 to move away from the cutter 4, so as to facilitate the discharge of the cut rubber block. After cutting, the cutter 4 rises, the second spring 16 returns to its original state, and the limit plate 20 contacts the rubber material again, so as to limit the length of the rubber block, which is conducive to obtaining a rubber block with a consistent length.

[0030] In this embodiment, the cutter 4 is provided with an arc block 21, and the arc block 21 can abut against the adjustment rod 19. In this way, it can be avoided that the adjustment rod 19 directly abuts against the cutter 4 and causes damage to the cutter 4.

[0031] In this embodiment, a feeding roller 10 is connected to one end of the workbench 1 away from the limit assembly. The feeding roller 10 is connected to the motor 13 through a belt. The motor 13 is started to drive the feeding roller 10 to rotate, so that the rubber on the feeding roller 10 moves to the cutting position of the cutter 4 so that the cutter 4 can cut the rubber, thereby avoiding damage caused by manual feeding.

[0032] In this embodiment, a conveyor belt 12 is provided at one end of the workbench 1 away from the feeding roller 10. A conveyor wheel is provided on the workbench 1, and the conveyor belt 12 is sleeved on the conveyor wheel. At the same time, the feeding roller 10 and the conveyor wheel can be connected through a belt. The belt is located inside the workbench 1. When the motor 13 drives the feeding roller 10 to rotate, it can also drive the conveyor wheel to rotate, so that the conveyor belt 12 conveys the cut rubber block to discharge. In this way, the feeding and discharging time can be shortened, and the cutting speed of the rubber material can be accelerated.

[0033] The working principle of an automatic rubber cutting machine is as follows: first, the rubber material is placed on the feeding roller 10, the motor 13 is started, and the feeding roller 10 and the conveyor belt 12 work at the same time. The feeding roller 10 conveys the rubber material. When the rubber material abuts against the limit plate 20, the hydraulic cylinder is started to drive the cutter 4 to move downward, and the cutter 4 drives the first sliding block 6 to move downward, and the first sliding block 6 drives the first spring 8 to move downward, and the first spring 8 drives the pressure plate 9 to move downward. When the pressure plate 9 contacts the rubber material, the cutter 4 continues to move downward, so that the first sliding block 6 compresses the first spring 8 to make the pressure plate 9 press against the rubber material. When the cutter 4 contacts the rubber material, the pressure plate 9 has fixed the rubber material, and the adjusting rod 19 presses against the arc block 21 of the cutter 4, so that the adjusting rod 19 moves in a direction away from the cutter 4 (the second spring 16 is compressed at this time), and at the same time, the adjusting rod 19 drives the limit plate 20 to move in a direction away from the cutter 4, and then the cutter 4 cuts the rubber material. After cutting, the hydraulic cylinder drives the cutter 4 to move upward, and the cutter 4 drives the first sliding block 6 to move upward, so that the first spring 8 returns to its original state, the pressure plate 9 leaves the rubber material, and the adjustment rod 19 is separated from the arc block 21, the second spring 16 returns to its original state, the limit plate 20 returns to its original position, the rubber material continues to feed, and contacts the limit plate 20 again, and the cut rubber material is discharged through the conveyor belt 12, and the cutter 4 descends for secondary cutting, and the cycle is repeated until the rubber material cutting is completed. At the same time, during the process of the cutter 4 descending and ascending, the cleaning bristles 23 on the mounting frame 2 contact the surface of the cutter 4, clean the surface of the cutter 4, and keep the cleanliness of the cutter 4.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
