Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating equipment technology, and in particular to a surface coating equipment for processing square bottom valve pockets. Background Technology
[0002] The surface coating equipment for square bottom valve bags is a specialized processing equipment that applies a layer of plastic film (such as polyethylene PE, polypropylene PP, etc.) to the surface of the substrate (usually paper, woven fabric, etc.) of the square bottom valve bag through a coating process to achieve functions such as moisture-proof, waterproof, enhanced sealing and physical strength.
[0003] The patent application number "202220595698.6" entitled "A Surface Coating Device for Square Bottom Valve Bags" describes a device that uses a fixed column to fix the position of a sliding side plate. By adjusting the position of the sliding side plate, the table can be adapted to square bottom valve bags of different sizes. This device is suitable for square bottom valve bags of different sizes, solving the problem that existing equipment cannot perform surface coating on different models of square bottom valve bags. It can perform surface coating on square bottom valve bags of different specifications, saving equipment investment costs.
[0004] However, the device has the following problems when in use: the height of the spray head is fixed, which means that the spray head cannot be adjusted according to different substrates. For substrates with rough surfaces or low rigidity, a closer spraying distance is required to ensure that the material can adhere tightly. For substrates with smooth surfaces or thick, hard substrates, a slightly farther distance is required to avoid splashing of the material due to excessive impact. Therefore, the fixed spray head may result in poor spraying effect on some substrates, reducing the coating effect of the square bottom valve bag on different substrates. Utility Model Content
[0005] The purpose of this invention is to provide a surface coating equipment for processing square bottom valve bags, which solves the problem that the height of the spray head in existing coating equipment is fixed, which means that the height of the spray head cannot be adjusted according to different substrates, which may result in poor spraying effect on some substrates and reduce the coating effect of square bottom valve bags on different substrates.

[0027] Reference Figure 1-4 This utility model provides a surface coating equipment for processing square bottom valve bags, comprising: a device body 1, a controller 2 on one side of the device body 1, a conveyor belt 3 inside the device body 1, a mounting plate 4 fixedly connected to the top of the device body 1, a sleeve 5 fixedly connected to the inner side of the mounting plate 4, a spring 6 fixedly connected to the inside of the sleeve 5, a telescopic rod 7 fixedly connected to the other end of the spring 6, a limit plate 8 fixedly connected to one end of the telescopic rod 7, and a screw 9 movably connected inside the mounting plate 4. By rotating the screw 9, the limit plate 8 can be moved back and forth, thereby adjusting the distance between the limit plates 8 on both sides of the conveyor belt 3, which is convenient for limiting square bottom valve bags of different sizes.
[0028] Support rods 11 are fixedly connected to both sides of the top of the device body 1. A top plate 12 is fixedly connected to the top of the support rods 11. A servo motor 13 is fixedly installed on the top of the left top plate 12. The output end of the servo motor 13 is fixedly connected to a lead screw 14 through a coupling. Lifting blocks 15 are movably connected to the outer walls of the support rods 11 and the lead screw 14. Water supply pipes 18 are fixedly connected to the inner sides of the two lifting blocks 15. A feed port 19 is provided at the top of the water supply pipe 18. A spray head 20 is provided at the bottom of the water supply pipe 18. The servo motor 13 can drive the lead screw 14 to rotate, which in turn can drive the lifting blocks 15 to rise and fall. The height of the spray head 20 can be adjusted according to the square bottom valve bag of different substrates, thereby improving the spraying effect on the square bottom valve bag.
[0029] The conveyor belt 3, servo motor 13 and spray head 20 are all electrically connected to the controller 2.
[0030] The mounting plate 4 has a screw hole on its side. The inner wall of the screw hole and the outer wall of the screw rod 9 are both threaded. The screw hole and the screw rod 9 are engaged with each other through the threads. When the screw rod 9 is rotated, one end of the screw rod 9 can drive the limiting plate 8 to move back and forth, thereby facilitating the adjustment of the position of the limiting plate 8.
[0031] The shape and size of the telescopic rod 7 match the shape and size of the sleeve 5. The telescopic rod 7 is slidably connected to the inner wall of the sleeve 5, which facilitates the forward and backward movement of the limiting plate 8 and also serves as a guide for the limiting plate 8.
[0032] The limiting plate 8 is L-shaped, and the bottom of the limiting plate 8 is attached to the top surface of the conveyor belt 3, which facilitates the limiting of the square bottom valve pocket.
[0033] A screw hole 16 is provided at the top center of the lifting block 15. The inner wall of the screw hole 16 and the outer wall of the lead screw 14 are both provided with threads. The screw hole 16 and the lead screw 14 are engaged with each other through threads. When the lead screw 14 rotates under the action of the servo motor 13, it can drive the lifting block 15 to rise and fall, thereby facilitating the adjustment of the height of the spray head 20 according to the square bottom valve pocket of different substrates.
[0034] The top of the lifting block 15 is provided with a guide hole 17. The lifting block 15 is slidably connected to the outer wall of the support rod 11 through the guide hole 17. The support rod 11 can guide and limit the lifting block 15, thereby improving the stability of the lifting block 15 during the lifting process.
[0035] Rotating shaft seats 10 are fixedly installed on the top of the device body 1 and one side of the limiting plate 8. One end of the lead screw 14 and the screw 9 are respectively rotatably connected to the rotating shaft seats 10 to facilitate the rotation of the lead screw 14 and the screw 9.
[0036] Working principle: Before coating, each screw 9 is rotated in sequence, which in turn drives each limiting plate 8 to move back and forth. The distance between the limiting plates 8 on both sides of the conveyor belt 3 can be adjusted according to the size of the square bottom valve bag, which facilitates the limiting of the square bottom valve bag. After adjustment, the height of the spray head 20 is adjusted according to the substrate of the square bottom valve bag. The servo motor 13 drives the screw 14 to rotate, which in turn drives the lifting block 15 to rise and fall. This allows for adjustment of the height of the water supply pipe 18 and the spray head 20. For example, for substrates with rough surfaces or low rigidity, the height of the spray head 20 can be lowered to facilitate material adhesion. For substrates with smooth surfaces or thick, hard substrates, the height of the spray head 20 can be raised to prevent spray material from splashing. After adjustment, the feed port 19 at the top of the water supply pipe 18 is connected to the external material supply pipe, and the coating of the square bottom valve bag can begin. The square bottom valve bag is transported by the conveyor belt 3. When it is transported to the bottom of the spray head 20, the spray head 20 can spray the spray material onto the surface of the square bottom valve bag.
