Description

Technical Field

[0001] The utility model relates to the technical field of tarpaulin production, in particular to a film coating machine for tarpaulin production. Background Technique

[0002] A tarpaulin (or waterproof cloth) is a high-strength waterproof material with good toughness and softness, and is often used as canvas (oil painting cloth), polyester with polyurethane coating or made into polyethylene plastics. Tarpaulins usually have strong grommets at the corners or edges for easy threading of ropes for tying, hanging or covering. Tarpaulin production includes fabric making, film coating and cooling, cutting, button forming and inspection, and finished product warehousing.

[0003] The existing film coating machines for tarpaulin production usually coat glue on a film and then bond to form a composite tarpaulin. However, it is found in actual production that when applying solvent-based glue for lamination, if there is too much glue, it will overflow, resulting in an unattractive appearance at the corners of the tarpaulin. Moreover, some glue does not cure in time after lamination, leading to differences in the quality of the tarpaulin. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a film coating machine for tarpaulin production, which can scrape off excess glue during tarpaulin lamination and assist in glue curing at the same time.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A film coating machine for tarpaulin production, including a frame, a protective cover is fixedly connected to the top of the frame, a guiding wheel group is arranged at the front end of the frame, a winding wheel group is arranged at the back of the frame, and further includes:

[0006] A glue coating mechanism, arranged on one side of the frame close to the guiding wheel group, for coating glue on the surface of the tarpaulin;

[0007] A scraper assembly, arranged at the back end of the glue coating mechanism in the frame, for scraping off excess glue on the surface of the tarpaulin;

[0008] A lamination mechanism, arranged in the middle of the protective cover for pressing and laminating the tarpaulin;

[0009] A heating and shaping mechanism, arranged on the top of the protective cover for shaping the laminated tarpaulin.

[0010] Optionally, the guiding wheel group includes a support plate, two guiding wheels are rotatably connected to the top end of the support plate, and the two guiding wheels are arranged vertically and staggeredly.

[0011] Optionally, the rewinding wheel set includes a support rod rotatably connected to the frame. A rewinding wheel is snap-fitted to the top of the support rod. The rewinding wheel is used for rewinding the tarpaulin. A lead screw handle is threadedly connected to the outer wall of the support rod. The lead screw handle can be adjusted along the length direction of the support rod to abut against the frame to restrict the rotation of the support rod.

[0012] Optionally, the gluing mechanism includes a glue pump. The output end of the glue pump is connected to a vertical pipe. The top of the vertical pipe is fixedly connected to a horizontal pipe. A plurality of spray heads are arranged on the top of the horizontal pipe.

[0013] Optionally, the scraper assembly includes a vertical rod. A horizontal scraper is rotatably connected to the top of the vertical rod. A spring is fixedly connected between the horizontal scraper and the vertical rod. The horizontal scraper and the vertical rod are elastically matched through the spring.

[0014] Optionally, the composite mechanism includes two composite rollers rotatably connected to the inner side wall of the protective cover. A rubber sleeve is sleeved on the outer wall of the composite roller.

[0015] Optionally, the heat setting mechanism includes a blower fixedly installed on the top of the protective cover. An electric heating wire is arranged at the bottom of the blower. The electric heating wire is used for heating the air flow introduced by the blower.

[0016] Optionally, a deflector is further arranged on the top of the protective cover. A plurality of deflector plates are fixedly connected to the inner side wall of the deflector.

[0017] The present utility model provides a film coating machine for tarpaulin production, which has the following beneficial effects:

[0018] In the film coating machine for tarpaulin production, through the settings of the frame, the protective cover, the guide wheel set, the gluing mechanism, the scraper assembly, the composite mechanism and the heat setting mechanism, the guide wheel set can guide the tarpaulin before the tarpaulin is compounded, so that the compounded tarpaulins are conveyed in layers without affecting each other. Before compounding, the gluing mechanism can apply glue to the upper tarpaulin, and the lower film can be directly pasted on the upper tarpaulin to compound the tarpaulin. After the glue is applied, the scraper will spread the glue evenly and scrape off the excess glue. Since the horizontal scraper fits on the tarpaulin through the spring, it can buffer and avoid damaging the tarpaulin. When passing through the composite roller, it is pressed and pasted together. Since the rubber sleeve has a deformation effect, it will not damage the tarpaulin. After compounding, the blower and the electric heating wire blow hot air to heat the tarpaulin, promote the volatilization of the glue and accelerate the curing process. After the rewinding of the tarpaulin is completed, the support rod of the rewinding wheel set can be turned down and disassembled by adjusting the lead screw handle, improving safety.

[0032] A heating and shaping mechanism 8 is arranged at the top of the protective cover 2 and is used for shaping the compounded tarpaulin.

[0033] The guiding wheel set 3 includes a support plate 31. At the top end of the support plate 31, two guiding wheels 32 are rotatably connected. The two guiding wheels 32 are arranged staggeredly up and down. The staggeredly arranged guiding wheels 32 can respectively guide the tarpaulin and the film.

[0034] The winding wheel set 4 includes a support rod 41 rotatably connected to the frame 1. At the top of the support rod 41, a winding wheel 42 is clamped. The winding wheel 42 is used for winding the tarpaulin. A lead screw handle 43 is threadedly connected to the outer wall of the support rod 41. The lead screw handle 43 can be adjusted along the length direction of the support rod 41 to abut against the frame 1 to restrict the rotation of the support rod 41. When the lead screw handle 43 is rotated clockwise, the lead screw handle 43 moves downward to abut against the frame 1 to restrict the rotation of the support rod 41. When the lead screw handle 43 is rotated counterclockwise, the lead screw handle 43 can move upward to release the restriction on the support rod 41, and the support rod 41 is flipped to the ground, so that the winding wheel 42 can be conveniently disassembled.

[0035] The compounding mechanism 7 includes two compounding rollers 71 rotatably connected to the inner side wall of the protective cover 2. A rubber sleeve 72 is sleeved on the outer wall of the compounding roller 71. The rubber sleeve 72 has elasticity and can effectively extrude and compound the tarpaulin and the film.

[0036] As a preferred embodiment, on the basis of the above method, further, the glue coating mechanism 5 includes a glue pump 51. The output end of the glue pump 51 is connected to a vertical pipe 52. The top of the vertical pipe 52 is fixedly connected to a horizontal pipe 53. A plurality of nozzles 54 are arranged at the top of the horizontal pipe 53. The vertical pipe 52 is arranged at the edge of the frame 1 and does not affect the film below. The horizontal pipe 53 is horizontally arranged below the tarpaulin. The plurality of nozzles spray glue in a straight line to ensure that the glue is effectively arranged on the tarpaulin.

[0037] As a preferred embodiment, on the basis of the above method, further, the scraping blade assembly 6 includes a vertical rod 61. At the top of the vertical rod 61, a horizontal scraping blade 62 is rotatably connected. A spring 63 is fixedly connected between the horizontal scraping blade 62 and the vertical rod 61. The horizontal scraping blade 62 and the vertical rod 61 are elastically matched through the spring 63.

[0040] In summary, when the film coating machine for tarpaulin production is in use, first, the tarpaulin and the film are respectively passed through the guide wheel group 3. The guide wheel group 3 can guide the tarpaulin and the film before the tarpaulin is compounded, so that the compounded tarpaulin is transported in layers without affecting each other. Before compounding, the glue coating mechanism 5 can coat the upper tarpaulin with glue. Specifically, the glue pump 51 extracts the glue and transports it through the vertical pipe 52 into the horizontal pipe 53, and then sprays it evenly through the nozzle. The lower film is directly pasted on the upper tarpaulin to compound the tarpaulin. After the glue is coated, the horizontal scraper 62 will smear the glue and scrape off the excess glue. Since the horizontal scraper 62 is attached to the tarpaulin through a spring, it can buffer and avoid damaging the tarpaulin. When passing through the compounding roller 71, it is pressed and pasted together. Since the rubber sleeve 72 has a deformation effect, it will not damage the tarpaulin. After compounding, the blower 81 and the electric heating wire 82 blow hot air to heat the tarpaulin, promote the volatilization of the glue, and accelerate the curing process. The tarpaulin roll after winding can be disassembled by turning down the support rod 41 through the adjusting screw handle 43 to improve safety.
