Description

Technical Field

[0001] The utility model belongs to the technical field of polyurethane new material processing, and particularly relates to a shearing machine for polyurethane new material processing. Background Technique

[0002] Polyurethane is a polymer material and is widely used in daily life, such as paints and coatings in furniture, refrigerators and freezers in household appliances, roof waterproof insulation layers and interior and exterior wall coatings in the construction industry, etc. It can also be made into various polyurethane materials, such as polyurethane soles, polyurethane fibers, polyurethane boards, and polyurethane sealants.

[0003] During the processing of polyurethane boards, a shearing machine is usually needed to cut the polyurethane boards to facilitate subsequent processing. However, when the existing shearing machine is in use, the operator needs to manually adjust the position of the polyurethane board to position it at the center. This method not only takes a lot of time but also increases the operation difficulty of the operator and reduces the work efficiency. Therefore, we propose a shearing machine for polyurethane new material processing. Content of the Utility Model

[0004] The purpose of the utility model is to provide a shearing machine for polyurethane new material processing. By setting a positioning component, specifically, after placing the polyurethane board on the cutting table, starting the motor to drive the bidirectional threaded rod to rotate clockwise, the two connecting seats will approach each other, and then the two moving seats will approach each other, so that the rotating rod will push the polyurethane board for positioning. At the same time, the rotating rod can also limit the polyurethane board to prevent the polyurethane board from shifting when moving, reducing the labor of the operator, lowering the positioning difficulty, and having a higher automatic positioning efficiency. It solves the problem that when the existing shearing machine is in use, the operator needs to manually adjust the position of the polyurethane board to position it at the center, which not only takes a lot of time but also increases the operation difficulty of the operator and reduces the work efficiency.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a shearing machine for polyurethane new material processing, including a table body. A cutting table is fixedly connected to the top of the table body. A positioning component is arranged above the cutting table. A fixing frame is arranged on the left side of the positioning component. The positioning component includes two support frames. Two fixing plates are fixedly connected to the corresponding sides of the two support frames. A bidirectional threaded rod is arranged between the two fixing plates. Two groups of threads are arranged on the outer surface of the bidirectional threaded rod, and the two groups of threads are arranged in opposite directions;

[0007] There are two moving seats arranged below the fixed plate. The two moving seats are symmetrically arranged, and the parts connected by the two moving seats are the same. A number of rotating rods are arranged inside the moving seats. The tops of the number of rotating rods are fixedly connected with rotating shafts, and the number of rotating shafts are all rotatably connected with the support frame. By setting the positioning component, specifically, after the polyurethane board is placed on the cutting table, the motor is started to drive the bidirectional threaded rod to rotate clockwise, and the two connecting seats will approach each other, then the two moving seats approach each other, and the rotating rods push the polyurethane board for positioning. At the same time, the rotating rods can also limit the polyurethane board to prevent the polyurethane board from shifting when moving, reducing the labor of the staff, lowering the positioning difficulty, and having a higher automatic positioning efficiency.

[0008] Further, a diversion plate is fixedly connected to the left side of the cutting table. The bottom of the fixed frame is fixedly connected to the top of the table body. The front and back of the bidirectional threaded rod are rotatably connected to the two support frames. A motor is fixedly connected to the front of the support frame located on the front. The output end of the motor on the back is fixedly connected to the front of the bidirectional threaded rod. Since the two threads on the outer surface of the bidirectional threaded rod 123 are arranged in the opposite direction, the two connecting seats 127 will approach each other or move away from each other.

[0009] Further, slide rails are fixedly connected to the bottoms of the two fixed plates. Two connecting frames are fixedly connected to the side of the moving seat away from the support frame. Sliders are fixedly connected to the tops of the two connecting frames. The tops of the sliders are slidably connected to the surfaces of the slide rails. The connecting seat 127 drives the slider 243 to slide on the slide rail 125, improving the stability during movement. The slider 243 drives the moving seat 124 to move together through the connecting frame 242.

[0010] Further, a connecting seat is fixedly connected to the opposite sides of the two sliders. A threaded hole is formed inside the connecting seat. The inner wall of the threaded hole is threadedly connected to the outer surface of the bidirectional threaded rod. The outer surface of the connecting seat is in contact with the fixed plate. The limiting plate is used to limit the connecting seat, enabling the connecting seat to perform a linear motion and improving the stability during movement.

[0011] Further, a hydraulic cylinder is fixedly connected to the top of the fixed frame. The output end of the hydraulic cylinder at the bottom is fixedly connected to a connecting block. A cutting knife is fixedly connected to the bottom of the connecting block. A pressing plate is in contact with the right side of the cutting knife. A cutting opening is formed in the top of the cutting table. By setting the pressing plate, specifically, after the pressing plate is lifted upward and the polyurethane board is moved under the pressing plate, the pressing plate presses the polyurethane board downward under the elastic action of the spring, which can play a certain fixing role for the polyurethane board during shearing, improving the cutting effect and reducing the occurrence of warping.

[0012] Further, there are two support plates arranged above the pressing plate. The two support plates are symmetrically arranged, and the parts connected by the two support plates are the same. One side of the support plate close to the fixing frame is fixedly connected to the surface of the fixing frame. A sliding hole is formed inside the support plate, and a vertical rod is slidably connected to the inner wall of the sliding hole. A spring is sleeved outside the vertical rod. The bottom of the vertical rod is fixedly connected to the surface of the pressing plate. The top of the spring is fixedly connected to the bottom of the support plate, and the bottom of the spring is fixedly connected to the surface of the pressing plate. The vertical rod is used to limit the pressing plate to prevent the pressing plate from shifting, and at the same time, it can make the pressing plate move in a straight line.

[0013] The utility model has the following beneficial effects:

[0014] 1. By setting the positioning component in the utility model, specifically, after placing the polyurethane board on the cutting table, start the motor to drive the bidirectional threaded rod to rotate clockwise. The two connecting seats will approach each other, and then the two moving seats will approach each other, causing the rotating rod to push the polyurethane board for positioning. At the same time, the rotating rod can also limit the polyurethane board to prevent the polyurethane board from shifting during movement, reducing the labor of workers, lowering the positioning difficulty, and having a higher automatic positioning efficiency.

[0015] 2. By setting the pressing plate in the utility model, specifically, after lifting the pressing plate upward and moving the polyurethane board under the pressing plate, the pressing plate presses the polyurethane board downward under the elastic action of the spring, which can play a certain fixing role for the polyurethane board during shearing, improve the cutting effect, and reduce the occurrence of warping.

[0016] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] A specific application of this embodiment is:

[0034] During use, place the polyurethane board on the cutting table 11, and then start the motor 126 to drive the bidirectional threaded rod 123 to rotate clockwise. Since the two threads on the outer surface of the bidirectional threaded rod 123 are arranged in opposite directions, the two connecting seats 127 will approach each other. The connecting seat 127 drives the slider 243 to slide on the slide rail 125 to improve the stability during movement. The slider 243 drives the moving seat 124 to move together through the connecting frame 242, so that the two moving seats 124 approach each other. When the rotating rod 241 contacts the polyurethane board, it pushes the polyurethane board, thus quickly positioning the polyurethane board. Then the motor 126 stops, and the rotating rod 241 can also limit the polyurethane board to prevent the polyurethane board from shifting during movement, reducing the labor of the staff, lowering the positioning difficulty, and having a higher automatic positioning efficiency. Then push the polyurethane board to move to the left, lift the pressing plate 134 upward so that the polyurethane board moves under the pressing plate 134, and then release the pressing plate 134. The pressing plate 134 presses down on the polyurethane board under the elastic action of the spring 343, which can play a certain role in fixing the polyurethane board during shearing, improving the cutting effect and reducing the occurrence of warping. Since the rotating rod 241 rotates on the moving seat 124 through the rotating shaft 244, it will not affect the movement of the polyurethane board and can make the movement of the polyurethane board smoother. Stop after moving the polyurethane board to the position where it needs to be cut. Then start the hydraulic cylinder 131 to drive the cutting knife 133 to move downward through the connecting block 132. The cutting knife 133 shears the polyurethane board through the cooperation with 14, and the sheared polyurethane board is discharged through the guide plate 111.
