Description

Technical Field

[0001] This utility model belongs to the field of plastic product processing, specifically, it relates to a plastic product processing and cutting device. Background Technology

[0002] Plastic products are widely used in various fields. They need to be cut during processing. Due to the different shapes of plastic products, it is difficult to fix them well during the cutting process, which affects the cutting quality of plastic products.

[0003] Compared with the document (authorization announcement number CN210389389U), this technology uses a sleeve and positioning rod with matching threaded structure to facilitate the operator to rotate the positioning rod to drive the positioning head to fix the plastic product, thereby improving the cutting quality of the plastic product. At the same time, its fixing is simple and easy for the operator to install and disassemble.

[0004] However, it has certain drawbacks: the height of its positioning head cannot be adjusted. When the plastic product is relatively high and the positioning head is relatively low, the center of gravity is low, which can easily lead to unstable fixing. Therefore, those skilled in the art have provided a plastic product processing and cutting device, and in view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] Please see Figures 1 to 8 This utility model provides a technical solution: a plastic product processing and cutting device, including a worktable 1, a guide column 2, a sleeve block 7 and an L-shaped fixing component. The upper end of the worktable 1 is fixed to the top plate 3 through the guide column 2. An electromagnetic slide rail 4 is provided at the lower end of the top plate 3. The lower end of the electromagnetic slide rail 4 is provided with a sliding end fixed to the drive seat 5. An electric cylinder 6 is located inside the drive seat 5. The telescopic end of the electric cylinder 6 passes through the drive seat 5 and is fixed to the sleeve block 7. The sleeve block 7 is provided with a housing for the motor 8. The output shaft of the motor 8 is fixed to the connecting component 9 through a coupling. An inner screw 11 for mounting the cutting blade 10 is fixed in the middle of the connecting component 9. The cutting blade 10 is fixed to the inner screw 11 through a limiting nut 12. An anti-slip ring 13 is fixed to the side of the inner screw 11.

[0035] Each guide post 2 is fitted with a guide block 14 on its outside. The guide block 14 is fitted with a ball bearing 15 inside. Each guide block 14 is fixed with a positioning box 16 on its side. The positioning box 16 is fitted with a pen-type electric push rod 17 inside. The telescopic end of the pen-type electric push rod 17 passes through to the side of the positioning box 16 and is fixed with an L-shaped block 18. Guide rods 19 are symmetrically fixed on the side of the L-shaped block 18. The guide rods 19 pass through to the inside of the wall of the positioning box 16. A positioning block 20 is fixed at the bottom of the positioning box 16.

[0036] The bottom of the workbench 1 is fixed to the movable seat 21 by a support column. A column 22 is symmetrically fixed at the upper end of the movable seat 21. A multi-stage electric push rod 23 is fixed inside the column 22. The top of the telescopic end of the multi-stage electric push rod 23 passes through the middle of the workbench 1 and is fixed to the positioning block 20 at the bottom of the positioning box 16. Considering that the height of the positioning head cannot be adjusted in the prior art, when the height of the plastic product is high and the positioning head is relatively low, the center of gravity is low and it is easy to cause the problem of insecure fixing. This utility model uses the L-shaped block 18 to fix the plastic product cut by the cutting blade 10. The fixing position of the L-shaped block 18 can be adjusted according to the height of the processed plastic product. That is, the extension or retraction of the telescopic end of the multi-stage electric push rod 23 will change the working height of the positioning box 16. After the height of the positioning box 16 changes, the working height of the L-shaped block 18 changes. After adjusting to the required height, the telescopic end of the pen-type electric push rod 17 can be used to drive the L-shaped block 18 to contact the plastic product.

[0037] The workbench 1 has a moving rail 25 fixed in the middle for two sliders 24 to move horizontally. A pad 26 is fixed on the top of each slider 24, and a fixing bolt 27 is threaded to the upper end of each slider 24. The fixing bolt 27 fixes the slider 24 to the moving rail 25. The pad 26 on the top of the slider 24 is used to place the plastic products to be processed.

[0038] The telescopic ends of the pen-type electric actuator 17, the multi-stage electric actuator 23, and the electric cylinder 6 are all covered with telescopic dust covers 28. The telescopic dust covers 28 serve to prevent dust from entering the telescopic ends of the pen-type electric actuator 17, the multi-stage electric actuator 23, and the electric cylinder 6.

[0039] The L-shaped block 18 has an inner contact pad 29 that contacts the plastic product. A thin-film pressure sensor 30 is installed inside the contact pad 29. The thin-film pressure sensor 30 is connected to the controller 31 on the top of the L-shaped block 18 via a wire. The front end of the controller 31 has a display screen 32. The contact pad 29 protects the contact surface between the L-shaped block 18 and the plastic product. The thin-film pressure sensor 30 inside the contact pad 29, together with the display screen 32 of the controller 31, helps the user know whether the L-shaped block 18 is in contact with the plastic product.

[0040] The L-shaped block 18 is symmetrically fixed with L-shaped parts 33 on both the front and rear sides. The horizontal ends of the two L-shaped parts 33 are provided with reserved holes for the installation of pen-type laser lights 34. The tail end of the pen-type laser light 34 is connected to the button at the front end of the L-shaped part 33 through a wire. By setting the pen-type laser light 34, the user can easily know the contact area of ​​the L-shaped block 18 when adjusting the multi-stage electric push rod 23.

[0041] The connector 9 is symmetrically fixed with positioning screws 35 on its side. The ends of the two positioning screws 35 pass through the positioning hole in the middle of the cutting blade 10 and are fixed with the positioning nut 36. The positioning nut 36 is fixed with the positioning screws 35 and the pressure plate 37. The pressure plate 37 has a clearance hole in the middle for the inner screw 11 to pass through. The pressure plate 37 is fixed with the limit nut 12. The positioning screws 35 play an auxiliary positioning role for the cutting blade 10 installed on the inner screw 11. Then, the positioning screws 35, the positioning nut 36 and the pressure cap play an auxiliary fixing role for the limit nut 12 used to fix the cutting blade 10. The pressure plate 37 can abut against the limit nut 12 to prevent it from loosening.

[0042] The upper side of the sleeve 7 is fixed with a negative pressure cover 38. A negative pressure nozzle 39 is installed on the top of the negative pressure cover 38, and the upper end of the negative pressure nozzle 39 is connected to a connecting pipe 40. The connecting pipe 40 is fixed to the front of the sleeve 7. A telescopic tube 41 is installed at the bottom of the connecting pipe 40. The bottom of the telescopic tube 41 extends into the interior of the storage box 44 and is fixed to the opening of the dust bag 42 by a fixing clamp. The other end of the dust bag 42 is connected to the negative pressure pipe 43 by a fixing clamp. The other end of the negative pressure pipe 43 is connected to the negative pressure pump 45 inside the storage box 44. The other end of the negative pressure pump 45 extends to the outside of the storage box 44. By setting up the negative pressure cover 38, the dust bag 42, the filter 46 and the negative pressure pump 45 in cooperation, the debris generated when cutting plastic products is collected, preventing the debris from splashing into the air and affecting the safety of workers.

[0043] The end of the negative pressure tube 43 is located inside the dust bag 42 and is threadedly connected to the filter element 46. The filter element 46 has multiple vent holes in the middle for gas flow, and a filter screen 47 is fixed in the middle of each vent hole. The filter screen 47 filters the plastic debris that is sucked into the dust bag 42 by the negative pressure. That is, the debris is left in the dust bag 42, and the air is discharged through the negative pressure pump 45.
