Description

Technical Field

[0001] The utility model belongs to the technical field of woven bag production, in particular to a cloth surface coating device for woven bag production. Background Art

[0002] Woven bags are a commonly used plastic bag, mainly used for packaging. Their raw materials are generally various chemical plastic materials such as polyethylene and polypropylene. They are usually used as packaging bags and can be used to package industrial and agricultural products, food, etc. In addition, in the fields of tourism and engineering materials, woven bags are also used for flood control and disaster relief;

[0003] In order to increase the waterproofness of woven bags, woven bags usually need to be laminated; pressing the plastic film on the end surface of the woven bag can increase the gloss and aesthetics of the woven bag after laminating the plastic film;

[0004] After searching, application (announcement) number: CN110328897B discloses a woven bag laminating device with a high laminating rate, including "a shell, a vacuum cleaner provided on the shell, and a first feed roller assembly provided in the shell for conveying the woven bag, a guide roller for guiding the woven bag, a cleaning roller assembly for cleaning the woven bag, a tension monitoring assembly for monitoring the tension of the woven bag, a heating device for heating the end surface of the woven bag, a second feed roller assembly for conveying a film, a winding roller for winding up the laminating woven bag, an extrusion roller for squeezing the woven bag, and a glue spraying assembly" and other technical features. It has the technical effects of "the provided woven bag laminating device can convey the woven bag in an orderly manner and can efficiently and synchronously laminarize the two end surfaces of the woven bag; the woven bag laminating is carried out in the shell to ensure that the laminating process is not affected by dust and impurities, thereby improving product quality";

[0005] However, during actual production of this equipment, it was found that the two feed rollers and the take-up roller for the film were far away from the second sealing door. In order to ensure the heating effect, the shell needs to be a relatively closed structure, which is not conducive to the replacement of the abrasive and woven bags on the film feed roller and the take-up roller, affecting actual use. Since the take-up roller is located at the bottom, when a roll of woven bag is coated, the end of the woven bag will fall from under the squeezing roller. At this time, due to the lack of tension in the woven bag, it is easy to cause the woven bag wound on the end of the take-up roller to loosen, resulting in gaps between the rolls, which is not conducive to subsequent storage and use.

[0006] In order to solve the above problems, the present application proposes a cloth surface coating device for woven bag production. Utility Model Content

[0007] The purpose of the utility model is to provide a cloth surface coating device for woven bag production, which solves the problems raised in the above background technology.

[0032] See also Figure 1-7 As shown, the utility model is a cloth coating device for woven bag production, comprising a machine body 1, in which two groups of film feeding rollers 11 and a group of winding rollers 12 are provided, a sliding first slide 2 is provided on one side of the bottom of the machine body 1, the two groups of film feeding rollers 11 are symmetrically installed in the first slide 2, a sliding second slide 3 is provided inside the first slide 2, and the winding roller 12 is installed in the second slide 3, and a box door 13 communicating with the first slide 2 is provided directly above the machine body 1, a locking component 5 is also provided between the machine body 1, the first slide 2, and the second slide 3, and a pressing component 4 for pressing the end of the woven bag is provided on the inner side of the second slide 3, and the pressing component 4 is also located directly below the film feeding roller 11.

[0033] Among them, the clamping component 4 includes a clamping plate 41 located directly below the film feeding roller 11. The top of the clamping plate 41 is arranged in an arc shape. Two symmetrical linear guide rods 42 are fixed on the inner side of the second slide 3 and staggered with the clamping plate 41. In this embodiment, the staggered cooperation between the clamping plate 41 and the linear guide rod 42 gives the clamping plate 41 more room for movement.

[0034] Among them, the clamping component 4 also includes a linear sleeve 43 that slides symmetrically on the outside of the linear guide rod 42, and a connecting plate 44 hinged between the clamping plate 41 and the linear sleeve 43, and also includes a clamping spring 45 that is sleeved on the outside of the linear guide rod 42 and connected to the two linear sleeves 43. In this embodiment, the clamping spring 45 can not only form extrusion when the clamping plate 41 contacts the woven bag, but also drive the clamping plate 41 to automatically reset without manual operation.

[0035] Among them, the pressing plate 41 presses the woven bag at the end of the film feeding roller 11 through the pressing spring 45. In this embodiment, the pressing plate 41 only contacts the woven bag when it is rolled to the end, avoiding the increase in energy consumption caused by constant contact.

[0036] Among them, the locking component 5 includes a locking plate 51 rotatably installed at one end of the inner side of the first slide 2 and a first locking block 52 fixed on the inner side of the second slide 3 and matched with one end of the locking plate 51, and a second locking block 53 fixed on the inner side of the body 1 and matched with the other end of the locking plate 51. In this embodiment, the locking component 5 can flexibly control the locking and disengagement between the body 1, the first slide 2, and the second slide 3.

[0037] Among them, the locking component 5 also includes a hand rod 54 fixed on the locking plate 51, the hand rod 54 is located at the front end of the second slide 3, and two locking springs 55 distributed along the circumferential direction are provided between the hand rod 54 and the second slide 3. The two locking springs 55 correspond to the two sides of the locking plate 51 respectively. In this embodiment, the two springs ensure the symmetry of force and ensure the reliable cooperation between the locking plate 51 and the first locking block 52 and the second locking block 53.

[0038] Among them, the locking plate 51 is engaged with the first locking block 52 and the second locking block 53 at the same time through two locking springs 55. In this embodiment, this ensures that when the locking spring 55 is in the reset state, the body 1, the first slide 2, and the second slide 3 are in a locked state.

[0039] It can be understood that first, a first slide is set up to slide inside the machine body and the winding roller is installed inside it, which is convenient for replacing the winding roller. At the same time, the second slide is slidably set in the first slide to facilitate the replacement of the second slide. The locking component set can flexibly control the locking and disengagement between the machine body, the first slide and the second slide; secondly, the clamping component is set to form compression at the end of the woven bag winding to prevent the end of the woven bag from loosening.

[0040] A specific application of this embodiment is: Figure 3The state shown is the laminating state of the present invention. During the laminating process, when the film feeding roller 11 is wound to the end, it will contact the pressure plate 41 as the diameter of the coil increases. As the diameter continues to increase, the pressure plate 41 will be pressed down. At this time, the linear sleeves 43 on both sides are driven to move outward under the action of the connecting plate 44, and the pressure spring 45 is stretched. The pressure plate 41 is pressed against the outside of the woven bag by the elastic force of the pressure spring 45. When the winding is completed, the end of the woven bag is separated from the bottom of the squeezing roller of the equipment. At this time, the winding roller continues to wind until all the woven bags are completely wound. The pressure of the pressure plate 41 can prevent the end woven bag from automatically loosening due to lack of tension. At this time, the staff rotates the locking component 5 to Figure 6 In the state shown, the second slide 3 is pulled outward by the external handle of the second slide 3, and the second slide 3 slides in the first slide 2, so that the wound woven bag can be removed from the film feeding roller 11, and then the second slide 3 is pushed back into the first slide 2. At this time, the box door 13 can be opened to assist work;

[0041] When it is necessary to add film to the winding roller 12, the locking member 5 is rotated to Figure 7 In the state shown, the first slide 2 is pulled outward, and the door 13 can also be opened to assist in the work, add the film on the winding roller 12, and then reset it to the inside of the machine body 1, and finally pass through the Figure 5 In the state shown, the locking member 5 locks the first slide 2 and the second slide 3 in the machine body 1;

[0042] The locking member 5 is used such that the first locking block 52 is fixed to the inner side of the second slide 3 and the second locking block 53 is fixed to the inner side of the body 1. Figure 5 As shown, at this time, the locking plate 51 is in a reset state through the locking spring 55, and the locking plate 51 is engaged with the first locking block 52 and the second locking block 53 at the same time. In this state, the body 1, the first slide 2, and the second slide 3 are in a locked state. According to the change of the rotation direction of the locking plate 51, the locking plate 51 will be disengaged from the first locking block 52 or the second locking block 53, while ensuring the locking between it and the second locking block 53 or the first locking block 52.
