Description

Technical Field

[0001] The utility model relates to the technical field of coated white board processing, in particular to a high-toughness coated white board paper shearing device. Background Art

[0002] High-toughness coated white cardboard is a type of cardboard with high toughness and tear resistance. It is characterized by its durability, high tear resistance, high work-to-break, and high dynamic strength. This cardboard is commonly used to make packaging cartons, especially after single-sided color printing. During actual processing, the raw cardboard needs to be cut to the appropriate size, requiring the use of shearing equipment. However, existing shearing equipment is overly simple in structure, has low precision, and suffers from low cutting efficiency, requiring improvement.

[0003] The technical solution disclosed in the Chinese patent with authorization announcement number CN219582954U releases the coated white paperboard by rotating the wheel, and accurately controls the different cutting lengths of the coated white paperboard by setting a precision ruler and a fixed block in the shearing groove.

[0004] However, this device still has some shortcomings: when the high-toughness coated white cardboard roll is released under the rotation of the rotating wheel, it tends to form a certain arc, which easily causes the actual length of the coated white cardboard passing through the cutter to be longer than the measured length. In addition, when the rotating wheel releases the coated white cardboard, if the coated white cardboard is about to or completely separated from the rotating wheel, the coated white cardboard cannot be effectively advanced.

The clamping assembly is connected to the support shaft 3. A synchronous belt 10 is movably connected to the frame 1. A support plate is provided on the frame 1 to support the load-bearing section of the synchronous belt 10. A knife holder 11 is provided on the frame 1 at the output end of the synchronous belt 10, with the upper surface of the knife holder 11 flush with the upper surface of the synchronous belt 10. A fixed frame 12 is connected to the frame 1 and slidably connected to a cutter 13, which is positioned above the knife holder 11. A hydraulic cylinder A14 is provided on the fixed frame 12 to drive the cutter 13 upward and downward. A slide 16 is slidably connected to the frame 1, and a linear module 15 is provided on the frame 1 to drive the slide 16 toward or away from the fixed frame 12. The distance measuring assembly is connected to the fixed frame 12. The distance measuring assembly includes a distance measuring probe 17 and a controller. The distance measuring probe 17 is electrically connected to the controller. The controller is electrically connected to the linear module 15 and the hydraulic cylinder A14. The distance measuring assembly measures the distance between the fixed frame 12 and the slide 16 in the working state, and controls the start and stop of the slide 16. At the same time, it controls the hydraulic cylinder A14 to drive the cutter 13 to rise and fall. The smoothing feeding mechanism includes a U-shaped frame 18, a U-shaped plate 20 and a pushing roller 24. The opening of the U-shaped frame 18 faces downward and is slidably connected to the slide 16. Two side holes 181 are symmetrically provided on the U-shaped frame 18. Two ear plates 21 are symmetrically provided on the U-shaped plate 20. The ear plates 21 on both sides are respectively inserted into the side holes 181 on the corresponding sides and slidably connected thereto, and a tensioning assembly 22 for pushing the U-shaped plate 20 downward is provided in the side hole. The U-shaped plate 20 is rotatably connected to a shaft 23. A push roller 24 is coaxially mounted on and attached to the shaft 23. The push roller 24 is located inside the opening of the U-shaped plate 20. A ratchet 25 is mounted on the end of the shaft 23. A spring 26 is mounted on the U-shaped plate 20. This spring 26 connects to a ratchet tooth 27 that fits into the ratchet groove of the ratchet 25. The U-shaped frame 18 is vertically slidably connected to the carriage 16. The carriage 16 is equipped with a hydraulic cylinder B19 that drives the U-shaped frame 18 upward and downward. When in operation, the smoothing and feeding mechanism cooperates with the timing belt 10 to smooth the white cardboard and convey it toward the knife block 11.

When the end of the coated white cardboard is below the cutter 13, the hydraulic cylinder B19 pulls up the U-shaped frame 18. The shape frame 18 makes it separate from the coated white cardboard, and at this time the push roller 24 keeps pressing the coated white cardboard, and the linear module 15 drives the slide 16 to slide back and reset. At this time, the push roller 24 adaptively slides in the opposite direction along the surface of the coated white cardboard, and smoothes the coated white cardboard on its return section. Then the slide 16 slides toward the fixed frame 12 again. At this time, the push roller 24 is limited and locked by the ratchet 25 and the ratchet 27. The push roller 24 cooperates with the synchronous belt 10 to push the coated white cardboard toward the cutter 13. When the ranging probe 17 detects that the distance between the slide 16 and it reaches the set value, the controller controls the linear module 15 to pause the action, and at the same time controls the hydraulic cylinder A14 to press the cutter 13, and the cutter 13 cuts and cuts the coated white cardboard.

[0028] Example 2

[0029] like Figure 2 As shown, the present invention proposes a high-toughness coated whiteboard paper shearing device. Compared with the first embodiment, this embodiment further specifically proposes the structure of a clamping assembly, which includes a slider 4, a wedge-shaped block 5, and a tooth block 8. Two through holes 31 are symmetrically provided on the support shaft 3, and a receiving groove 32 is provided at one end of the support shaft 3 that is away from the through holes 31 on both sides, which is connected to the through hole 31 on the corresponding side. The two sliders 4 are respectively disposed in the through holes 31 on the corresponding side and are slidably connected to the inner wall thereof. The size of the sliders 4 is the same as that of the receiving groove 32, and a slide groove is provided in the slider 4, and a tensioning spring is provided in the slide groove. The wedge-shaped block 5 is inserted into the slide groove and is slidably connected to the inner wall thereof. The wedge-shaped block 5 is connected to the outer end of the tensioning spring, and the inclined surfaces of the wedge-shaped blocks 5 on both sides are away from each other. A bidirectional screw 6 is provided in the support shaft 3 to rotate coaxially with the support shaft 3. The two ends of the bidirectional screw 6 respectively pass through the slider 4 on the corresponding side and are spirally connected to them. A tooth groove 33 is provided at one end of the support shaft 3, and a tooth block 8 is slidably provided in the tooth groove 33. The tooth block 8 is coaxially connected to the pin shaft 7. The other end of the pin shaft 7 is inserted into the bidirectional screw rod 6 and slides radially along the bidirectional screw rod 6. A handle is provided on the side of the tooth block 8 away from the bidirectional screw rod 6 at a position deviated from its axis.

[0030] In this embodiment, the coated white paperboard roll is put on the support shaft 3, and the coated white paperboard roll is pushed to continue sliding. At this time, the wedge-shaped block 5 is automatically retracted under pressure. When the coated white paperboard roll is between the wedge-shaped blocks 5 on both sides, the handle is manually pulled outward, and the handle is used to drive the tooth block 8 and the pin shaft 7 to pull the tooth block 8 out of the tooth groove 33. Then, the handle is rotated to drive the tooth block 8, the pin shaft 7 and the bidirectional screw rod 6 to rotate. The rotation of the bidirectional screw rod 6 drives the sliders 4 on both sides to approach each other, and the wedge-shaped block 5 approaches synchronously and clamps and limits the coated white paperboard roll, thereby improving the linearity of the coated white paperboard during transportation.

[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
