Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically a plastic sheet cutting device. Background Technology

[0002] The existing strip cutting device has an operating table, a conveying mechanism, and a cutting mechanism. The plastic sheet is first placed on the operating table, and the operator manually pushes the plastic sheet on the operating table to the conveying mechanism. The conveying mechanism can continuously transport the plastic sheet to the cutting mechanism. Finally, the cutting mechanism continuously cuts the plastic sheet that is conveyed. However, due to the large size of the plastic sheet, the friction between the plastic sheet and the operating table during the process of pushing the plastic sheet to the conveying mechanism will affect the pushing efficiency. At the same time, the plastic sheet is also prone to tilting during the pushing process, which will affect the cutting effect. Utility Model Content

[0003] The purpose of this invention is to provide a plastic sheet cutting device, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The plastic sheet cutting device includes a cabinet, on which a mounting frame is provided. Mounting grooves are respectively provided on both sides of the mounting frame. Slider blocks are respectively provided inside the two mounting grooves. A fixed rod is provided on the slider and slidably connected to the mounting frame. A bolt is threaded onto the mounting frame, and the bottom end of the bolt is rotatably connected to the slider. Friction shafts driven by a reduction motor are provided inside the mounting frame and between the two sliders. The two friction shafts rotate in opposite directions. A through groove for the sheet material to pass through is provided on the mounting frame. A knife holder is provided on the through groove. A lifting cylinder is provided on the mounting frame, and a cutting blade is also included. The output end of the lifting cylinder passes through the mounting frame and is fixedly connected to the cutting blade. Guide rods are symmetrically provided on the cutting blade, passing through the mounting frame and slidably connected to it. A placement platform is provided on the cabinet and on one side of the mounting frame. A push plate is slidably connected to the placement platform. A bottom groove is provided on the placement platform, and a telescopic cylinder is provided inside the bottom groove. The output end of the telescopic cylinder is fixedly connected to the push plate.

[0005] Preferably, slide rails are provided on both sides of the push plate, and slide grooves are symmetrically formed on the upper surface of the placement platform, with the slide rails and slide grooves being slidably connected.

[0006] Preferably, sleeves are provided on both sides of the upper end of the mounting bracket, and the guide rod is slidably connected to the sleeves.

[0007] Preferably, the upper end of the bolt is provided with a cap.

[0008] Preferably, the two sliders are connected by a reinforcing plate.

[0009] The beneficial effects of this utility model are:

[0010] When in use, this device uses a telescopic cylinder and a pusher plate to replace manual pushing of the plate on the placement platform towards the two friction shafts, thus facilitating the pushing of the plate between the two friction shafts and its transmission. Furthermore, once one end of the plate is aligned with the pusher plate, the pusher plate's pushing action on the plate can largely prevent the plate from tilting during manual pushing, thereby improving the cutting effect and resulting in good performance.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-5As shown, a plastic sheet cutting device includes a cabinet 2, on which a mounting frame 3 is mounted. Mounting slots are formed on both sides of the mounting frame 3, and sliders 4 are respectively installed inside the two mounting slots. A fixing rod 5, slidably connected to the mounting frame 3, is mounted on the slider 4. Bolts 6 are threaded onto the mounting frame 3, and the bottom end of the bolts 6 is rotatably connected to the sliders 4. Friction shafts 8, driven by a reduction motor 7, are installed inside the mounting frame 3 and between the two sliders 4. The two friction shafts 8 rotate in opposite directions. A through slot is formed on the mounting frame 3 for the sheet material 1 to pass through. A knife holder 9 is provided on the through groove, a lifting cylinder 10 is provided on the mounting frame 3, and a cutter 11 is also provided. The output end of the lifting cylinder 10 passes through the mounting frame 3 and is fixedly connected to the cutter 11. Guide rods 12 are symmetrically provided on the cutter 11. The guide rods 12 pass through the mounting frame 3 and are slidably connected to the mounting frame 3. A placement platform 13 is provided on the cabinet 2 and on one side of the mounting frame 3. A push plate 14 is slidably connected to the placement platform 13. A bottom groove is opened on the placement platform 13. A telescopic cylinder 15 is provided inside the bottom groove. The output end of the telescopic cylinder 15 is fixedly connected to the push plate 14.

[0019] The horizontal height of the upper surface of the placement platform 13 is not lower than the horizontal height of the friction shaft 8 directly mounted on the mounting bracket 3. When the plate 1 passes between the two friction shafts 8, the plate 1 will not come into contact with the friction shaft 8 located below.

[0020] The two friction shafts 8 rotate in opposite directions, and at the same speed. The two reduction motors 7 can drive their respective friction shafts 8 to rotate. The two friction shafts 8 achieve engagement with the plate 1, and the plate 1 is continuously transported to the cutter 11 for strip cutting through the friction between the friction shafts 8 and the plate 1.

[0021] The plastic sheets 1 processed by this slitting device are all of uniform size and have a rectangular shape. When slitting the plastic sheets 1, the sheet 1 is first placed on the placement table 13, then one end of the sheet 1 is abutted and aligned with the push plate 14. Next, the telescopic cylinder 15 is activated, and its output end drives the push plate 14 to move. During this movement, the push plate 14 moves the sheet 1 on the placement table 13. When the front end of the sheet 1 moves to the two friction shafts 8, the two rotating friction shafts 8 cut the sheet 1 into strips. The friction shaft 8 and the plate 1 are engaged, and the friction between the friction shaft 8 and the plate 1 is used to continuously transport the plate 1 from one side of the friction shaft 8 to the other side. When the plate 1 is engaged by the friction shaft 8, the telescopic cylinder 15 stops pushing the plate 1 and controls the push plate 14 to reset. When the plate 1 moves a predetermined distance, the friction shaft 8 stops moving. Then, the lifting cylinder 10 controls the cutter 11 to move downward. The plate 1 is located between the cutter holder 9 and the cutter 11. Through the cooperation between the cutter 11 and the cutter holder 9, the plate 1 is cut into strips.

[0022] After completing one cut, the lifting cylinder 10 drives the cutter 11 to move upward, and then the friction shaft 8 continues to rotate and transport the plate 1. When the plate 1 moves a predetermined distance again, the friction shaft 8 stops moving, and then the cutter 11 and the cutter holder 9 continue to cut the plate 1. By controlling the repeated movement of the plate 1, the plate 1 is cut into strips.

[0023] For plates 1 of different thicknesses, the movement of the two sliders 4 and the friction shaft 8 between the two sliders 4 can be controlled by rotating the bolt 6, thereby controlling the distance between the two friction shafts 8 to facilitate the transport of plates 1 of different thicknesses. The position of the friction shaft 8 located at the bottom remains unchanged. The bolt 6 can be threadedly connected to the mounting bracket 3, allowing the bolt 6 to move up and down on the mounting bracket 3. At the same time, since the lower end of the bolt 6 is rotatably connected to the slider 4, the bolt 6 can also drive the slider 4 to move up and down when it moves up and down.

[0024] Furthermore, slide rails 16 are provided on both sides of the push plate 14, and slide grooves are symmetrically provided on the upper surface of the placement platform 13. The slide rails 16 are slidably connected to the slide grooves to improve the stability of the push plate 14 when it moves on the placement platform 13.

[0025] Furthermore, sleeves 17 are respectively provided on both sides of the upper end of the mounting bracket 3, and the guide rod 12 is slidably connected to the sleeves 17, which helps to improve the stability of the cutter 11 when it moves up and down.

[0026] Furthermore, a cap 18 is provided at the upper end of the bolt 6 to facilitate the control of the rotation of the bolt 6.

[0027] Furthermore, the two sliders 4 are connected by a reinforcing plate 19 to improve the stability of the two sliders 4.
