Description

Technical Field

[0001] This utility model relates to the technical field of woven bag coating equipment, and specifically discloses a woven bag coating device. Background Technology

[0002] Woven bags are packaging bags made primarily of plastic raw materials such as polypropylene (PP) or polyethylene (PE), which are extruded and stretched into flat filaments and then woven. Because their texture resembles snakeskin, they are commonly known as "snakeskin bags." They are characterized by high strength, weather resistance, and low cost. During the woven bag processing, in order to improve the waterproof performance of the woven bags, a laminating device is usually used to laminate a protective film onto the outside of the woven bag.

[0003] Chinese patent CN219467169U discloses a woven bag laminating device, including a laminating box, a laminating roller, a heating roller, a drive mechanism for moving the heating roller left and right, and a receiving roller. A bracket is set on one side of the laminating box, and a woven bag feeding roller is rotatably connected to the bracket. A cleaning device is connected between the bracket and the laminating box. Two film feeding rollers are rotatably connected to the side of the laminating box near the inlet. Advantages of this invention: This device places the coating roller inside the coating box, which can prevent dust from adhering to the surface of the film material. The cleaning device cleans the dust from the woven bag, which can make the film material adhere tightly to the woven bag. In addition, the first tensioning guide wheel and the second tensioning guide wheel tension the woven bag and the film material, preventing wrinkles and effectively improving the coating quality. However, during the use of the above device, additional transfer equipment is required to transfer the woven bag and the film material, which is not conducive to saving the cost of woven bag coating processing and affects the practicality of the above device to a certain extent. Therefore, in order to solve the above problems, this invention proposes a woven bag coating device. Utility Model Content

[0004] The present invention aims to provide a woven bag coating device that facilitates the replacement and transfer of woven bag rolls and film rolls, enriches the functions of the first unwinding mechanism, the winding mechanism and the second unwinding mechanism, and improves the practicality of the device.

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

[0006] A woven bag laminating device includes a base, with a first unwinding mechanism and a rewinding mechanism respectively disposed at both ends of the base. A second unwinding mechanism is disposed on one side of the first unwinding mechanism, and tensioning mechanisms are disposed on both sides of the second unwinding mechanism. A heat-pressing mechanism is disposed on one side of one of the tensioning mechanisms. Both the first unwinding mechanism and the rewinding mechanism include a first bracket. Two first clamps are rotatably connected to the upper end of the first bracket, and a first unwinding shaft is detachably connected between the two first clamps. The second unwinding mechanism includes a third bracket, with two second clamps rotatably connected to both ends of the third bracket. A second unwinding shaft is detachably connected to one side of each second clamp. Two casters are symmetrically disposed on both sides of the lower part of the first bracket and the second bracket.

[0007] As a further feature of the above solution, limit rods are provided at both ends of the base, and a first limit groove is provided at one end of the first bracket. The limit rods abut against the inner wall of the first limit groove to facilitate the alignment of the first unwinding mechanism and the winding mechanism with the base.

[0008] As a further feature of the above scheme, the winding mechanism is located on the side of the hot pressing mechanism away from the first unwinding mechanism. One end of a first clamp in the winding mechanism is connected to a second motor, which can drive the first clamp and the first unwinding shaft in the winding mechanism to rotate and wind up the coated woven bag.

[0009] As a further feature of the above solution, a reserved groove is provided on the inner side of the base, and a second limiting groove is provided at one end of the second bracket. The bottom of the limiting groove is in contact with the bottom of the second limiting groove, which can restrict the position of the second unwinding mechanism and facilitate the alignment of the second unwinding mechanism with the base and tensioning mechanism.

[0010] As a further feature of the above solution, the tensioning mechanism includes a second bracket, with two limiting rollers rotatably connected to the upper end of the second bracket, and two first telescopic rods symmetrically connected to the lower part of the second bracket, so as to adjust the distance between the limiting rollers and the base by controlling the extension and retraction of the first telescopic rods, thereby tensioning the woven bag and the film material.

[0011] As a further provision of the above solution, the hot pressing mechanism includes two fourth supports, each with two hot pressing rollers rotatably connected to both ends. One end of each hot pressing roller is connected to a first motor, which drives the hot pressing roller to rotate. Multiple support rollers arranged in a linear array are provided on the inner side of the two hot pressing rollers. A coating roller is provided above each of the two hot pressing rollers. A fifth support is rotatably connected to the outer side of the two coating rollers. Two second telescopic rods are connected to the upper center of the fifth support. The distance between the coating roller and the hot pressing roller can be adjusted by extending and retracting the second telescopic rods to limit the position of the film and the woven bag, and to press the woven bag and the film together during the hot pressing process. A sixth support is connected to the outer side of the second telescopic rod.

[0012] The sixth bracket in this invention is equipped with a PLC controller on one side for controlling the first telescopic rod, the second telescopic rod, the first motor, the second motor, and the hot press roller. All of the above components are connected to the PLC controller via power lines and control lines. In the terminal device, the operation of simultaneously controlling the two first telescopic rods and the second telescopic rod is programmed into corresponding operation codes and transmitted to the PLC controller via data lines. The PLC controller can then be used to simultaneously control the extension and retraction of the two first telescopic rods and the second telescopic rod. The two ends of the hot press roller and the support roller are rotatably connected to the two brackets respectively. At least one of the multiple casters in the winding mechanism and the two unwinding mechanisms is a brake wheel. The first unwinding shaft and the second unwinding shaft are both air shafts. The first chuck and the second chuck are both common air shaft chucks.

[0013] The present invention has the following beneficial effects during use:

[0014] The use of the pre-reserved slot and two limiting rods in the base facilitates the alignment of the base with the winding mechanism and the two unwinding mechanisms. The use of multiple casters in the winding mechanism and the two unwinding mechanisms facilitates the adjustment of the positions of the above mechanisms, so as to realize the transfer of woven bags and film materials before and after lamination, provide space for the replacement of woven bags and film materials, reduce the impact of the components in the tensioning mechanism and the hot pressing mechanism on the replacement of woven bags and film materials, enrich the functions of the above mechanisms, and improve the practicality of the above mechanisms and the device.

[0015] The use of two tensioning mechanisms can restrict the position of the woven bag and the film material, while adjusting the distance between the limiting roller and the base by controlling the extension and retraction of the first telescopic rod. This adjusts the tension of the woven bag and the film material between the two limiting rollers in the same tensioning mechanism, preventing wrinkles from forming in the woven bag and the film material during the hot-pressing and laminating process, and ensuring the quality of the woven bag lamination.

A second unwinding mechanism 4 is provided on one side of the first unwinding mechanism 2. Tensioning mechanisms 3 are provided on both sides of the second unwinding mechanism 4. A hot pressing mechanism 5 is provided on one side of one of the tensioning mechanisms 3. Both the first unwinding mechanism 2 and the winding mechanism 6 include a first bracket 21. Two first clamps 22 are rotatably connected to the upper end of the first bracket 21. A first unwinding shaft 23 is detachably connected between the two first clamps 22. The second unwinding mechanism 4 includes a third bracket 41. Two second clamps 42 are rotatably connected to both ends of the third bracket 41. A second unwinding shaft 43 is detachably connected to one side of the second clamps 42. Two universal wheels 211 are symmetrically provided on both sides below the first bracket 21 and the second bracket 31.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, both ends of the base 1 are provided with limiting rods 12, and one end of the first bracket 21 is provided with a first limiting groove 212. The limiting rods 12 are in contact with the inner wall of the first limiting groove 212, which facilitates the alignment of the first unwinding mechanism 2 and the winding mechanism 6 with the base 1.

[0027] like Figure 1 and Figure 2 As shown, the winding mechanism 6 is located on the side of the hot pressing mechanism 5 away from the first unwinding mechanism 2. One end of the first clamp 22 in the winding mechanism 6 is connected to a second motor 61, which can drive the first clamp 22 and the first unwinding shaft 23 in the winding mechanism 6 to rotate and wind up the coated woven bag.

[0028] like Figure 2 and Figure 4 As shown, a reserved groove 11 is provided on the inner side of the base 1, and a second limiting groove 411 is provided at one end of the second bracket 31. The bottom of the limiting groove is in contact with the bottom of the second limiting groove 411, which can limit the position of the second unwinding mechanism 4 and facilitate the alignment of the second unwinding mechanism 4 with the base 1 and the tensioning mechanism 3.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, the tensioning mechanism 3 includes a second bracket 31, with two limiting rollers 32 rotatably connected to the upper end of the second bracket 31, and two first telescopic rods 33 symmetrically connected to the lower part of the second bracket 31, so as to adjust the distance between the limiting rollers 32 and the base 1 by controlling the extension and retraction of the first telescopic rods 33, thereby tensioning the woven bag and the film material.

[0030] like Figure 1 , Figure 2and Figure 5 As shown, the hot pressing mechanism 5 includes two fourth supports 51. Two hot pressing rollers 52 are rotatably connected to both ends of the two fourth supports 51. A first motor 521 is connected to one end of each hot pressing roller 52, which can drive the hot pressing roller 52 to rotate. Multiple support rollers 53 arranged in a linear array are provided on the inner side of the two hot pressing rollers 52. A coating roller 54 is provided above each of the two hot pressing rollers 52. A fifth support 55 is rotatably connected to the outer side of the two coating rollers 54. Two second telescopic rods 56 are connected to the upper middle part of the fifth support 55. The distance between the coating roller 54 and the hot pressing roller 52 can be adjusted by the extension and retraction of the second telescopic rods 56, so as to limit the position of the film and the woven bag and press the woven bag and the film tightly during the hot pressing process. A sixth support 57 is connected to the outer side of the second telescopic rods 56.

[0031] The woven bag coating device disclosed in this embodiment, before use, places the woven bag roll and the film roll on the outside of the first unwinding shaft 23 and the second unwinding shaft 43 in the first unwinding mechanism 2 and the second unwinding mechanism 4, respectively.

Following the same operation as placing the first unwinding shaft 23, place the first unwinding shaft 23 and the empty sleeve in the winding mechanism 6, and align the winding mechanism 6 and the base 1.

[0032] The woven bag roll and the film roll are fixed by the expansion key in the first unwinding shaft 23 and the second unwinding shaft 43. The end of the woven bag roll is pulled and passed through the gap between the two limiting rollers 32 near the first unwinding mechanism 2, and then through the gap between the two film rolls. After aligning the ends of the two film rolls with the ends of the woven bag, they are pulled out through the gap between the other two limiting rollers 32. Pulling the hot pressing mechanism 5 in, the PLC controller simultaneously controls the extension of the two second telescopic rods 56, moving the two film-coating rollers 54 downwards to squeeze the film and woven bag. The second telescopic rods 56 are then closed, and the PLC controller starts the two hot pressing rollers 52 to heat the film and woven bag, covering the outside of the woven bag with the film. The film-coated woven bag is then pulled so that one end is wrapped around the sleeve. The PLC controller starts the first motor 521 and the second motor 61, which respectively drive the hot pressing rollers 52, the first chuck 22 in the winding mechanism 6, the first unwinding roller, and the sleeve to rotate and wind up the woven bag, thus realizing continuous film coating of the woven bag.
