Description

Technical Field

[0001] This utility model relates to the field of PVC cable tray production technology, and more specifically, to a cutting device for PVC cable tray production. Background Technology

[0002] PVC cable trays, also known as polyvinyl chloride cable trays, are commonly referred to as wiring ducts, electrical wiring ducts, or cable management ducts. With the development of modern construction and electrical engineering, the demand for PVC cable trays is increasing daily. In the traditional PVC cable tray production process, the cutting stage is one of the key factors affecting production efficiency.

[0003] Most PVC cable tray cutting equipment on the market can only perform single-segment cutting of cable trays, and cannot simultaneously cut multiple segments. Furthermore, since each cut needs to be performed individually, the overall processing time is increased, resulting in long production times, low efficiency, and difficulty in meeting the needs of large-scale production. In addition, when cutting cable trays of different lengths, it is necessary to manually measure the length with a ruler, mark it with a marker, and then cut it with a table saw. This is not only cumbersome for PVC cable tray spacing, but also extremely inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for the production of PVC cable trays, which can simultaneously cut multiple sections of cable trays and cut cable trays of different lengths, with high cutting efficiency.

[0005] This utility model is achieved through the following technical solution:

[0006] A cutting device for producing PVC cable trays includes a workbench with support frames on both sides. Two support frames are connected by a support plate. Several parallel cutting units are slidably mounted on the support plate. The cutting units are connected by a scissor-type structure, and a first cylinder is connected to one end of each cutting unit. A frame is also provided on the support plate, and a clamping unit is provided on the frame. The clamping unit is located at the feed end of the workbench.

[0007] Furthermore, the cutting unit includes a slider, an L-shaped plate, and a cutter. A guide rail is provided on the support plate, the slider is slidably connected to the guide rail, the L-shaped plate is fixedly connected to the slider, and a second cylinder is provided on the L-shaped plate. The driving end of the second cylinder is connected to the cutter.

[0008] Furthermore, a limiting plate is provided on the cutting unit located in the middle, and the limiting plate is connected to the support plate by screws.

[0009] Furthermore, the clamping unit includes a third cylinder, and the driving end of the third cylinder is connected to a clamping plate.

[0010] Furthermore, the clamping plate is provided with a positioning groove, and the inner wall of the positioning groove is provided with a protective pad.

[0011] Furthermore, the positioning groove is V-shaped or arc-shaped.

[0012] Furthermore, the clamping unit also includes a motor, which is installed in the frame. The output end of the motor passes through the frame and is connected to a fixing plate. The third cylinder is fixedly installed at the bottom of the fixing plate.

[0013] Furthermore, a movable plate is provided on one of the cutting units, and the driving end of the first cylinder is connected to the movable plate.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0015] In this invention, multiple cutting units can simultaneously cut multiple segments of the PVC trough, eliminating the need for individual cutting of each segment, thus shortening cutting time and improving cutting efficiency. By coordinating a first cylinder and a scissor-type structure, the first cylinder drives the scissor-type structure to extend or retract, thereby adjusting the length between multiple cutting units and achieving fixed-distance cutting of the PVC trough. This method is suitable for cutting troughs of different lengths and offers good practicality. The clamping unit can clamp and fix the PVC trough, improving the stability during PVC trough cutting.

[0027] Example 1

[0028] like Figures 1-4 As shown, this embodiment provides a cutting device for PVC trough production, including a workbench 1. Support frames 2 are provided on both sides of the workbench 1. The two support frames 2 are connected by a support plate 3. A plurality of parallel cutting units 4 are slidably installed on the support plate 3. The cutting units 4 are connected by a scissor structure 5. A first cylinder 6 is connected to one end of the cutting unit 4. A frame 7 is also provided on the support plate 3. A clamping unit 8 is provided on the frame 7. The clamping unit 8 is located at the feeding end of the workbench 1.

[0029] Multiple cutting units 4 can simultaneously cut multiple segments of the PVC trough, eliminating the need for individual cutting of each segment, thus shortening cutting time and improving cutting efficiency. Through the cooperation of the first cylinder 6 and the scissor-type structure 5, the first cylinder 6 drives the scissor-type structure 5 to extend or retract, thereby adjusting the length between the multiple cutting units 4 and achieving fixed-distance cutting of the PVC trough. This is suitable for cutting troughs of different lengths and has good practicality. The clamping unit 8 can clamp and fix the PVC trough, improving the stability during PVC trough cutting.

[0030] In this embodiment, the cutting unit 4 includes a slider 44, an L-shaped plate 41, and a cutter 43. A guide rail 9 is provided on the support plate 3. The slider 44 is slidably connected to the guide rail 9, and the L-shaped plate 41 is fixedly connected to the slider 44. A second cylinder 42 is provided on the L-shaped plate 41, and the driving end of the second cylinder 42 is connected to the cutter 43. The cooperation between the slider 44 and the guide rail 9 improves the stability of the cutting unit 4 during movement. In use, the second cylinder 42 drives the cutter 43 to descend, thereby cutting the PVC wire groove on the workbench 1.

[0031] In this embodiment, a limiting plate 11 is provided on the cutting unit 4 located in the middle, and the limiting plate 11 is connected to the support plate 3 by screws. The limiting plate 11 can fix the middle cutting unit 4. When the first cylinder 6 drives the scissor structure 5 to move, the middle cutting unit 4 does not move, while the cutting units 4 at both ends move, which can improve the stability of the cutting unit 4 when changing pitch.

[0032] In this embodiment, the clamping unit 8 includes a third cylinder 81, and the driving end of the third cylinder 81 is connected to a clamping plate 82. In use, the third cylinder 81 drives the clamping plate 82 to descend, so that the clamping plate 82 presses against the surface of the PVC wire groove, thereby fixing the PVC wire groove and ensuring the accuracy of cutting.

[0033] In this embodiment, the clamping plate 82 is provided with a positioning groove 84, and a protective pad 85 is provided on the inner wall of the positioning groove 84. The protective pad 85 can protect the PVC cable tray and prevent the PVC cable tray from being worn.

[0034] In this embodiment, the positioning groove 84 is V-shaped or arc-shaped. The V-shaped or arc-shaped groove can improve the fixing effect of the PVC cable tray and prevent it from slipping.

[0035] In this embodiment, the clamping unit 8 further includes a motor 83, which is installed inside the frame 7. The output end of the motor 83 passes through the frame 7 and is connected to a fixing plate. The third cylinder 81 is fixedly installed at the bottom of the fixing plate. The motor 83 can drive the fixing plate to rotate, thereby driving the third cylinder 81 to rotate, and simultaneously driving the clamping plate 82 to rotate, so that the clamping plate 82 can clamp and fix the inclined PVC groove, so as to cut PVC grooves with different inclination angles.

[0036] In this embodiment, a movable plate 10 is provided on the cutting unit 4, and the driving end of the first cylinder 6 is connected to the movable plate 10.

[0037] The working principle of a cutting device for PVC cable tray production is as follows: The PVC cable tray is placed on the workbench 1. A third cylinder 81 lowers the pressure plate 82, pressing it firmly against the surface of the PVC cable tray to fix it in place. A first cylinder 6 moves the movable plate 10, simultaneously extending or shortening the scissor-type structure 5 to adjust the spacing between multiple cutting units 4. Then, a second cylinder 42 lowers the cutter 43 to cut the PVC cable tray, achieving multi-segment fixed-distance cutting of the PVC cable tray.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
