Description

Technical Field

[0001] The utility model relates to the field of awning cloths, in particular to a device for processing corners of awning cloths of automobiles. Background Art

[0002] Tarpaulin is also called tarpaulin. It is a thick cotton or linen fabric that is strong and fold-resistant and has good waterproof performance. It is named because it was originally used for sails. It is generally made of plain weave, with a small amount of twill weave. Both the warp and weft yarns are made of multiple strands. Therefore, tarpaulin is mostly used on the top of the car to protect the items loaded in the car.

[0003] At present, in the production and preparation process of automobile awning cloth, its edges and corners are mostly cut to make them cut flat and convenient for subsequent further processing of the edges and corners. However, traditional cutting devices are mostly composed of cutting tools. In the actual cutting process, since the automobile awning cloth has a certain flexibility, the operator needs to pull the awning cloth on both sides of the cutting surface to stretch it out in order to achieve smooth cutting of the automobile awning cloth. This makes the cutting process more cumbersome and labor-intensive. Therefore, we make improvements on this and propose a corner processing device for automobile awning cloth. Utility Model Content

Such terms are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0031] like Figure 1-Figure 5 As shown, this embodiment provides a device for processing the edges and corners of a car awning cloth, comprising two support platforms 1 arranged opposite to each other, a cutting unit 2 being installed between the two support platforms 1, and a positioning unit 3 being installed on the surface of the cutting unit 2 for positioning the cut edge of the car awning cloth;

[0032] The positioning unit 3 includes a U-shaped frame 31 and guide cylinders 32 arranged on both sides of the surface of the U-shaped frame 31. Slide blocks 33 are slidably arranged in the guide cylinders 32. The bottoms of the two slide blocks 33 are commonly connected to a pressing plate 34, and the tops of the two slide blocks 33 are commonly connected to a supporting frame 35.

[0033] The support frame 35 includes a frame body 350, the top end of the slider 33 extends into the frame body 350 and is slidably assembled therewith, and a compression spring 351 fixed to the slider 33 is connected to the frame body 350, and a return spring 36 connected to the top wall of the U-shaped frame 31 is connected to the surface of the compression plate 34;

[0034] like Figure 5 As shown, under the action of the return spring 36, the pressing plate 34 maintains a height separated from the support platform 1 in the initial state, and the elastic force of the pressing spring 351 is greater than the action of the return spring 36, so as to ensure that when the frame 350 moves downward to overcome the action of the return spring 36 and drive the pressing plate 34 to move synchronously, the pressing spring 351 still maintains a certain supporting state without being greatly compressed;

[0035] The cutting unit 2 comprises a cutting tool 21 hinged to two support platforms 1 , and a wing plate 22 is fixed to the surface of the cutting tool 21 .

[0036] When actually cutting the corners of the car tarpaulin, the corners of the tarpaulin can be passed through the two U-shaped frames 31 in sequence, and then the cutting tool 21 is turned over. During the turning process of the cutting tool 21, the wing plate 22 thereon rotates synchronously, and the wing plate 22 gradually contacts with the corresponding frame 350 below during the rotation process. The frame 350 subjected to the contact force will slide in the direction of the slider 33, and the slider 33 will synchronously drive the pressing plate 34 to slide in the direction of the car tarpaulin below while sliding.

[0037] When the pressing plate 34 contacts the surface of the automobile tarpaulin, the slider 33 is supported by the bottom of the support platform 1, so that the slider 33 and the corresponding frame 350 slide relative to each other. During the relative sliding process, the pressing spring 351 is compressed synchronously. When the pressing spring 351 is compressed to a certain height, the pressing plate 34 under the action of the pressing spring 351 can stably contact and press the automobile tarpaulin below it, and the pressing spring 351 overcomes the action force of the return spring 36 in the initial compression stage, so that the pressing plate 34 is pressed against the surface of the automobile tarpaulin, ensuring that the tarpaulin is stable and not easy to slide.

[0038] At this time, the cutting tool 21 also needs to contact the position of the corner of the tarpaulin to be cut, and then further pressing the cutting tool 21 can achieve smooth cutting of the corner of the car tarpaulin, and there is no need to manually pull on both sides of the cutting part, which effectively simplifies the processing steps;

[0039] At the same time, after the cutting is completed, with the resetting action of the cutting tool 21, the clamping plate 34 is subjected to the force of the reset spring 36 and the clamping spring 351 to slide and reset, releasing the contact with the tarpaulin below, thereby facilitating the removal of the tarpaulin and the tarpaulin corners after cutting.

[0040] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
