Description

Technical Field

[0001] This utility model relates to the field of spare tire cover cutting technology, specifically a cover cutting device that facilitates adjustment of the cutting length. Background Technology

[0002] A spare tire cover is a movable partition between the trunk and the spare tire compartment of a car. It serves as both a cover for the spare tire compartment and a floor for the trunk, primarily decorating the trunk, supporting items within, and covering the spare tire and vehicle tools. Currently, the most common spare tire covers use PHC board as the base material, requiring cutting and edge binding during manufacturing. In existing technologies, after the non-woven fabric is pressed onto the spare tire cover, the non-woven fabric needs to be cut to leave edges for edging the cover.

[0003] For example, Chinese Patent Publication No. CN 206561673 U discloses a non-woven fabric pressing and cutting device for automobile spare tire cover. This device uses a simultaneous pressing and cutting operation to achieve composite edge binding of the cover. It also adds a gauge to assist in the positioning of the cover and cuts the non-woven fabric according to the gauge, which greatly improves the cutting accuracy of the non-woven fabric. At the same time, the adhesive on the pressing surface is uniform, ensuring the consistency of the subsequent edge binding process and production. Moreover, the entire operation process is fully automatic, realizing the continuity of the whole machine operation, greatly improving work efficiency and reducing enterprise costs.

[0004] However, the above-mentioned patents still have some problems in use. For example, the existing spare tire cover cutting device uses a vertical lifting cutting component to cut the workpiece. Moreover, manual feeding is required, and workers pull the moving support to cut workpieces of different lengths. However, the precise length of pipe cutting is not easy to control, making it inconvenient to use. Summary of the Invention

[0019] In a preferred embodiment, both the measuring wheel 8 and the guide wheel 11 are mounted on the lifting plate 12. A threaded adjusting rod 13 is rotatably provided on the upper end of the lifting plate 12. The upper end of the threaded adjusting rod 13 is located on the upper end of the L-shaped support plate 7. When the threaded adjusting rod 13 rotates, it can drive the lifting plate 12 to rise and fall, thereby using the lifting plate 12 to drive the measuring wheel 8 and the guide wheel 11 to move, realizing the adjustment of the position of the measuring wheel 8 and the guide wheel 11, which enables the measuring wheel 8 and the guide wheel 11 to better contact workpieces of different thicknesses.

[0020] In a preferred embodiment, the bottom end of the lifting plate 12 is provided with multiple sets of support members 14, and the measuring wheel 8 and the guide wheel 11 are rotatably arranged inside the support members 14. The bottom end of the L-shaped support plate 7 is provided with a limiting plate 15 for the lifting plate 12 to move. The support members 14 facilitate the installation of the measuring wheel 8 and the guide wheel 11, and the limiting plate 15 facilitates the lifting of the lifting plate 12 in the vertical direction.

[0021] In a preferred embodiment, the brush 10 and the dust suction plate 9 are disposed at the front end of the measuring wheel 8 and the guide wheel 11, and the threaded adjustment rod 13 is provided with a scale. The workpiece is first cleaned by the brush 10 and the dust suction plate 9 and then measured by the measuring wheel 8, resulting in higher measurement accuracy.

[0022] In a preferred embodiment, the workbench 1 is provided with a cutting groove, which is located directly below the cutting blade 6. The workbench 1 is provided with a control panel 24. The cutting groove facilitates the cutting of the workpiece by the cutting belt. The control panel 24 can be connected to the measuring wheel 8 and the hydraulic telescopic cylinder 4, and controls the operation of the hydraulic telescopic cylinder 4 according to the measurement result of the measuring wheel 8.

[0023] The working principle of this utility model is as follows: In use, the measuring length of the measuring wheel 8 is set according to the actual length of the workpiece. The workpiece to be cut is placed on the transmission belt 3, with both ends of the transmission belt 3 located at the lower inner side of the L-shaped support plate 7. The L-shaped support plate 7 is used to limit the two ends of the workpiece. The transmission belt 3 drives the workpiece to move. When the workpiece passes the measuring wheel 8, the measuring wheel 8 rotates to measure the length of the workpiece and transmits the measurement result to the control panel 24 in real time. The control panel 24 controls the operation of the hydraulic telescopic cylinder 5 according to the measurement result of the measuring wheel 8. When the measuring wheel 8 reaches the preset length, the control panel 24 controls the hydraulic telescopic cylinder 5 to open. The hydraulic telescopic cylinder 5 drives the cutting blade 6 to descend and cut the workpiece. Example 2:

[0024] Please see Figures 1-4 A dust-collecting plate 9 is provided between the two L-shaped support plates 7. A brush 10 is provided on one side of the bottom end of the dust-collecting plate 9.

The second sprocket 22 is fixedly provided on the drive motor shaft 23 of the transmission belt 3. Dust-collecting holes are evenly spaced at the bottom end of the dust-collecting plate 9.

[0025] When the transmission belt 3 is driven by the drive motor shaft 23, the drive motor shaft 23 can also drive the second sprocket 22 to rotate. When the second sprocket 22 rotates, it can drive the first sprocket 20 to rotate through the chain 21. The first sprocket 20 can drive the acceleration box 19 to open. After the acceleration box 19 accelerates the speed of the drive motor shaft 23, it drives the dust suction fan blade 18 to rotate at high speed, which makes the dust suction box 16 generate negative pressure. The dust suction box 16 absorbs the dust on the surface of the workpiece through the dust suction plate 9, and when the brush 10 contacts the upper surface of the workpiece, it can sweep the dust on the surface of the workpiece. The dust is absorbed by the dust suction plate 9 and enters the dust collection box 16. The dust is filtered by the filter screen 17. After the workpiece is processed by the brush 10 and the dust suction plate 10, the length is measured by the measuring wheel 8, which makes the measuring wheel 8 more accurate and can also remove dust from the workpiece for convenient subsequent use.
