Description

Technical Field

[0001] The invention relates to the field of tent tarpaulin hot pressing, in particular to a tent tarpaulin hot pressing system. Background Art

[0002] Tarpaulin (also known as waterproof fabric) is a high-strength, highly flexible, and waterproof material. Due to its waterproof and mildew-resistant properties, tarpaulin is widely used in our daily lives. For example, it is used in cargo transportation on trucks, trains, and ships; it is used to cover open-air warehouses at stations, docks, seaports, and airports; and it is used as a variety of tents, including military tents, construction tents, and folding tents. Each type of tent is made of different materials and has different performance characteristics. Some are thicker and more resistant to harsh living environments, while others are rain and snowproof and some provide shade.

[0003] Currently, there is a tent that includes a main tarpaulin and a side tarpaulin heat-sealed to the top edge of the main tarpaulin. The edge of the main tarpaulin is provided with a first folded edge bent inwardly, a drawstring is provided in the first folded edge, and a perforation is provided. A support tube for supporting the tent is provided on the outside of the first folded edge, and the drawstring connects the support tube to the tarpaulin. At this time, the side tarpaulin extends downward from above the support tube, around the support tube, and a second folded edge bent inwardly is provided at the lower edge of the side tarpaulin away from the main tarpaulin. The upper edge of the side tarpaulin is heat-sealed to the main tarpaulin, that is, at the upper edge of the side tarpaulin, the inner side of the side tarpaulin is heat-sealed to the outer side of the main tarpaulin.

[0004] During the processing of this type of tent, the hot pressing process of the first folding edge, the second folding edge, the upper edge of the side tarpaulin and the main tarpaulin, as well as the adjustment of the front and back sides of the main tarpaulin and the side tarpaulin during hot pressing, makes the hot pressing of the entire tent tarpaulin a very complicated process, greatly reducing production efficiency.

[0005] The Chinese patent application number CN201821715307.X discloses a tarpaulin production line, but the production line cannot meet the needs of this production. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a tent tarpaulin hot pressing system, which facilitates the hot pressing molding of the first folding edge, the second folding edge, the upper edge of the side tarpaulin and the main tarpaulin, thereby improving production efficiency.

[0007] The utility model is realized through the following technical scheme: a tent tarpaulin hot pressing system, comprising a unwinding device, a first hot pressing device, a first direction-adjusting roller group, a second hot pressing device, a third hot pressing device, and a second direction-adjusting roller group arranged in sequence from front to back, wherein the first direction-adjusting roller group is located below the second hot pressing device, and the first direction-adjusting roller group is located below the third hot pressing device; after the main tarpaulin is unwound, it passes through the second direction-adjusting roller group, the third hot pressing device, and the first direction-adjusting roller group in sequence and enters the second hot pressing device; the side tarpaulin passes through the first hot pressing device and enters the second hot pressing device; in the second hot pressing device, the main tarpaulin and the side tarpaulin are hot-pressed and connected to form a whole tarpaulin.

[0008] When the utility model is in use, the unwinding device unwinds the main tarpaulin and the side tarpaulin, and the main tarpaulin is transmitted from front to rear. After the main tarpaulin is unwound, it is adjusted backward by the second direction-adjusting roller group and transmitted forward to enter the third hot pressing device for hot-pressing and folding to form a first folding edge. After passing through the first direction-adjusting roller group, the main tarpaulin moves backward to enter the second hot pressing device. After passing through the first hot pressing device, the side tarpaulin forms a second folding edge and then enters the second hot pressing device. In the second hot pressing device, the main tarpaulin and the side tarpaulin are hot-pressed and connected to form a whole tarpaulin, thereby facilitating the hot-pressing forming process of the first folding edge, the second folding edge, the upper edge of the side tarpaulin and the main tarpaulin, thereby improving production efficiency.

[0009] Preferably, a tensioning device, a punching device, and a winding device are sequentially provided behind the second hot pressing device.

[0010] This preferred solution facilitates the subsequent process of punching holes on the first folded edge and rolling up the entire tarpaulin by providing a tensioning device, a punching device, and a rolling device.

[0011] Preferably, before the whole tarpaulin is hot-pressed and formed, the side tarpaulin is located above the main tarpaulin.

[0012] When this preferred solution is in use, the side tarpaulins and the main tarpaulin are separated up and down, thereby avoiding interference between the side tarpaulins and the main tarpaulin. At the same time, since the main tarpaulin needs to be located below the side tarpaulin during hot pressing in the second hot pressing device, interference between the main tarpaulin and the side tarpaulin is also avoided when entering the second hot pressing device.

[0013] Preferably, a first bending device is provided between the unwinding device and the first hot pressing device, the first bending device drives the lower edge of the side tarpaulin to bend upward and inward, and forms a second fold under the heat pressure of the first hot pressing device.

[0014] A second bending device is provided between the second hot pressing device and the first hot pressing device. The second bending device drives the inner side surface of the upper edge of the side tarpaulin to bend downward and inward. The inner side surface of the bent part is hot-pressed with the outer side surface of the main tarpaulin to form a hot pressing surface.

[0015] This preferred solution facilitates the bending and guiding of the upper and lower edges of the side tarpaulin by the provision of the first bending device and the second bending device, thereby facilitating the hot pressing of the hot pressing device. By hot pressing the inner side surface of the bent portion of the side tarpaulin and the outer side surface of the main tarpaulin to form a hot pressing surface, when the side tarpaulin and the main tarpaulin are hydraulically placed for use, the tension borne by the side tarpaulin and the main tarpaulin is shared by the entire hot pressing surface, thereby enhancing the connection strength between the side tarpaulin and the main tarpaulin.

[0016] Preferably, the first bending device and the second bending device have the same structure, both including a bending plate, a support rod fixed to the bending plate and supporting the side tarpaulin, and an adjustment structure connecting the bending plate and the bracket. The bending plate is provided with a V-shaped bending hole for the side tarpaulin to pass through, and the height of the inner opening of the bending hole is flush with the top surface of the support rod.

[0017] In this preferred embodiment, the bending holes are provided to provide a guide for the upper and lower edges of the side tarpaulin when they are bent.

[0018] Preferably, the adjustment structure includes a horizontal plate with a first long hole, the horizontal plate is bolted to the bracket, a vertical plate is fixed to the horizontal plate, the vertical plate is provided with threaded holes arranged along the height direction and passing through the vertical plate, the bent plate is provided with a second long hole extending along the height defense line, and a bolt threadedly connected to the threaded hole is passed through the second long hole.

[0019] This preferred solution facilitates adjustment of the position of the bending plate along the width direction of the main tarpaulin by providing the horizontal plate and the first long hole, and facilitates adjustment of the position of the bending plate in the height direction by providing the second long hole and the vertical plate.

[0020] Preferably, a walking plate extending along the width direction of the main tarpaulin and located below the first hot pressing device is provided between the first bending device and the unwinding device, and a conveying roller for the main tarpaulin and the side tarpaulin to pass around is provided below the walking plate.

[0021] This preferred solution facilitates walking by providing a walking board, thereby facilitating maintenance of the equipment.

[0022] The beneficial effects of the present invention are as follows: the unwinding device unwinds the main tarpaulin and the side tarpaulin, and the main tarpaulin is conveyed from front to rear. After the main tarpaulin is unwound, it is adjusted backward by the second direction-adjusting roller group and conveyed forward to enter the third hot pressing device for hot-pressing and folding to form a first folding edge. After passing through the first direction-adjusting roller group, the main tarpaulin moves backward to enter the second hot pressing device. After the side tarpaulin passes through the first hot pressing device, a second folding edge is formed, and then it enters the second hot pressing device. In the second hot pressing device, the main tarpaulin and the side tarpaulin are hot-pressed and connected to form a whole tarpaulin, thereby facilitating the hot-pressing forming process of the first folding edge, the second folding edge, the upper edge of the side tarpaulin and the main tarpaulin, thereby improving production efficiency.

[0035] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0036] Refer to the attached Figure 1-8The present invention provides a hot pressing method for a tent tarpaulin. A system for implementing the method includes an unwinding device, a first bending device 11, a first hot pressing device 1, a second steering roller group 7, a second bending device 12, a second hot pressing device 2, a third hot pressing device 3, a main bending device, a second steering roller group 7, a tensioning device 4, a punching device 5, and a winding device 6, which are arranged in sequence from front to back. The first steering roller group 8 is located below the second hot pressing device 2, and the second steering roller group 7 is located below the third hot pressing device 3.

[0037] The unwinding device includes a main unwinding roller 10 and a side unwinding roller 9 for unwinding the main tarpaulin and the side tarpaulin respectively. The main unwinding roller 10 is located behind the side unwinding roller 9. A walking plate 13 extending along the width direction of the main tarpaulin and located below the first hot pressing device 1 is also provided between the first bending device 11 and the unwinding device. A conveying roller for the main tarpaulin and the side tarpaulin to bypass is provided below the walking plate 13.

[0038] The first bending device 11 and the second bending device 12 have the same structure, both comprising a bending plate 28, a support rod 27 fixed to the bending plate 28 and supporting the side tarpaulin, and an adjustment structure connecting the bending plate 28 and the bracket. The bending plate 28 is provided with a V-shaped bending hole 26 for the side tarpaulin to pass through.

[0039] The side of the bending plate 28 connected to the support rod 27 is the first side of the bending plate 28. The bending hole 26 includes a first perforation extending axially along the support rod 27, and a second perforation arranged obliquely. The first perforation extends to the first side, and the second perforation is located directly below the first perforation. The second perforation extends upward and obliquely away from the first side. The end of the second perforation away from the first side is connected to the end of the first perforation away from the inner side, thereby forming a V-shape. The inner opening of the bending hole 26 is the connection port between the first perforation and the first side, and its height is flush with the top surface of the support rod 27. The inner angle of the bending hole 26 is the angle between the first perforation and the second perforation, which determines the bending angle of the side tarpaulin.

[0040] Since the first bending device 11 and the second bending device 12 bend different edges of the side tarpaulin, the position and use direction of the bending plate 28 need to be properly adjusted during use.

[0041] The adjustment structure includes a horizontal plate 24 with a first long hole, the horizontal plate 24 is bolted to the bracket, a vertical plate 29 is fixed to the horizontal plate 24, the vertical plate 29 is provided with threaded holes arranged along the height direction and passing through the vertical plate 29, the bent plate 28 is provided with a second long hole 25 extending along the height defense line, and a bolt threadedly connected to the threaded hole is passed through the second long hole 25.

[0042] The first hot pressing device 1, the second hot pressing device 2, the third hot pressing device 3, the main bending device, the punching device 5, the tensioning device 4, and the winding device 6 are all existing technologies, and the third hot pressing device 3 is also provided with a guide tube for guiding the pull rope into the first folding edge, and the guide tube is also existing technology.

[0043] The steering roller group includes two rotating rollers arranged along the height direction.

[0044] A method for hot pressing a tent tarpaulin, comprising the following steps:

[0045] a. Unwind the main tarpaulin and the side tarpaulin backwards, with the outer side 17 of the main tarpaulin positioned above the inner side; the outer side 19 of the side tarpaulin positioned below the inner side, and with the side tarpaulin positioned above the main tarpaulin and inside the edge of the main tarpaulin;

[0046] b. The main tarpaulin is conveyed backward from below, passing over a number of conveyor rollers, and then forward after passing through the second set of steering rollers. At this time, the outer side surface 17 of the main tarpaulin is located below the inner side surface. Under the guidance of the main bending device, the edge of the main tarpaulin is bent upward and inward, and the first folded edge 21 is formed under the heat pressing of the third hot pressing device 3. When the main tarpaulin moves forward to the front of the second hot pressing device 2, it passes through the first set of steering rollers and then moves backward into the second hot pressing device 2. At this time, the outer side surface 17 of the main tarpaulin is located above the inner side surface.

[0047] c. At the same time, after the side tarpaulin passes over several guide rollers, it is guided by the first bending device 11 so that the side tarpaulin moves away from the edge of the first fold, i.e., the lower edge, and is bent upward and inward. After being hot-pressed by the first hot-pressing device 1, the second fold 22 is formed. The side tarpaulin continues to move backward and is guided by the second bending device 12 so that the upper edge of the side tarpaulin is bent downward and inward. That is, at the bent portion, the outer side surface is located above the inner side surface. The side tarpaulin then enters the second hot-pressing device 2.

[0048] d. In the second hot pressing device 2, the side tarpaulin is positioned above the main tarpaulin, with the upper edge of the side tarpaulin located between the first folded edge and the second folded edge. The inner side of the bent portion of the side tarpaulin is hot pressed against the outer side of the tarpaulin, so that the main tarpaulin and the side tarpaulin are hot pressed together to form a complete tarpaulin;

[0049] e. After passing through the second hot pressing device 2, the entire tarpaulin enters the punching device 5 for punching and is then rolled up.

[0050] In this solution, the first fold is the heat-pressed connection between the inner side 16 of the main tarpaulin after the edge of the main tarpaulin is bent, and the second fold is the heat-pressed connection between the inner side of the side tarpaulin after the lower edge of the side tarpaulin is bent. The upper and lower edges of the side tarpaulin are based on the attached Figure 2 , where the upper edge is heat-sealed to the main tarpaulin and the lower edge forms a second fold.

[0051] In this embodiment of the present invention, when the side tarpaulins and the main tarpaulin are hydraulically placed for use, the tension borne by the side tarpaulins and the main tarpaulin is shared by the entire hot pressing surface 23, thereby enhancing the connection strength between the side tarpaulins and the main tarpaulin.

[0052] Refer to the attached Figure 9 The direction of the arrow is the direction of tension. When the outer side surface 19 of the side tarpaulin and the outer side surface 17 of the main tarpaulin are hot-pressed, the side tarpaulin is stretched downward around the hot-pressing surface 23. The edge of the hot-pressing surface 23, that is, point A in the figure, will be subjected to tension and will be torn first, so the connection strength between the side tarpaulin and the main tarpaulin is low.

[0053] Refer to the attached Figure 10 When the second hot pressing device 2 is performing hot pressing, when the first folded edge is located at the hot pressing surface 23 and the second folded edge, the inner side surface 18 of the side tarpaulin is located below the outer side surface, and the second folded edge is located below. Therefore, it is inconvenient to process the second folded edge, or the side tarpaulin needs to be adjusted and flipped, which will also increase the equipment cost.

[0054] Of course, the above description is not limited to the above examples. Technical features not described in the present invention can be achieved by or by adopting existing technologies, which will not be described here. The above embodiments and drawings are only used to illustrate the technical solutions of the present invention and are not limitations of the present invention. The present invention is described in detail with reference to the preferred implementation methods. Ordinary technicians in this field should understand that changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention do not depart from the purpose of the present invention and should also fall within the scope of protection of the claims of the present invention.
