Abstract

The application relates to the technical field of film covering, and discloses a film covering device for processing environment-friendly waterproof handbags, which comprises a main body and further comprises a deviation rectifying mechanism installed in the interior of the main body and used for correcting waterproof films. The rotation of the rotating rod drives the synchronous rotation of the surface pushing ring.

Description

Technical Field

[0001] This invention relates to the field of coating technology, specifically to a coating device for processing environmentally friendly waterproof tote bags. Background Technology

[0002] An environmentally friendly waterproof tote bag processing laminating device is an automated laminating equipment adapted to paper and non-woven tote bags, using a solvent-free biodegradable pre-coating film process. It includes components such as a frame, conveyor, film material correction, and constant temperature hot pressing, and is used for production to make the finished product biodegradable and recyclable, enabling continuous batch production and solving the defects of traditional equipment such as high pollution, poor film adhesion, and damage to the handles. Existing environmentally friendly waterproof tote bag fabric laminating devices mostly involve unwinding the waterproof membrane roll, then heating and pressing it with the fabric using extrusion rollers before rewinding. However, during the conveying process, the waterproof membrane is prone to lateral displacement due to uneven tension, causing the membrane to deviate from the center of the fabric. This results in misalignment of the fabric laminating area, uneven bonding, and reduced lamination accuracy. Summary of the Invention

[0003] The purpose of this invention is to provide a coating device for processing environmentally friendly and waterproof tote bags, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a laminating device for processing environmentally friendly waterproof tote bags, comprising a main body and further comprising: The correction mechanism is installed inside the main body and is used to correct the waterproof membrane. The correction mechanism includes a fixed plate fixedly connected inside the main body, and several fixed blocks are fixedly connected to the top of the fixed plate. The fixed blocks are symmetrically distributed around the main body. Anti-folding mechanism: The anti-folding mechanism is installed on the right side of the correction mechanism to reduce the overlap of the waterproof membrane; There are two fixed blocks, which are used to support the movement of the swing assembly.

[0005] Furthermore, the main body includes: A coating assembly is disposed inside the main body; An auxiliary component, located on the left side of the coating component, is used for winding up the finished fabric.

[0006] Furthermore, corrective bodies also include: A swing assembly is positioned on top of the covering assembly; The edge-pushing component is located on the side wall of the swing component and is used to flatten the curled edge.

[0007] Furthermore, the anti-folding mechanism includes: A leveling component is located to the right of the swing component; The leveling component, located at the bottom of the leveling component, is used to level the waterproof membrane.

[0008] Furthermore, the coating assembly includes an extrusion rod rotatably connected inside, and a heating rod is provided on the right side of the coating assembly; The heating rod is internally rotatably connected to the main body; The main body has several contact rods inside, which are distributed at equal intervals around the main body; There are five contact rods, four of which are located at the bottom of the heating rod, and the other is flush with the heating rod.

[0009] Furthermore, the auxiliary components include a winding rod rotatably connected inside the main body, with a placement rod provided at the bottom of the winding rod; The placement rod is rotatably connected to the side wall of the main body, and a rotating rod is provided at the top of the placement rod; The rotating rod is rotatably connected to the inside of the fixed block; The two ends of the rotating rod are rotatably connected to the inside of the main body.

[0010] Furthermore, the oscillating assembly includes a rotating plate rotatably connected to the top of the fixed block; The bottom of the rotating plate is equipped with several pushing rings, which are arranged in pairs and symmetrically distributed around the main body. The push ring is fixedly connected to the outer surface of the rotating rod; Among them, there are four push rings, and each group of push rings is distributed in a cross pattern. When the push rings move, they will continuously push the rotating plate to rotate.

[0011] Furthermore, the pushing edge assembly includes a sliding sleeve that is slidably connected to the surface of the rotating plate, and an elastic sheet is rotatably connected to the bottom of the sliding sleeve; The end of the elastic piece away from the sliding sleeve is rotatably connected to the top of the fixed plate.

[0012] Furthermore, the leveling assembly includes a wave rod rotatably connected inside the main body, a transmission belt sleeved on the outer surface of the wave rod, and the end of the transmission belt away from the wave rod sleeved on the outer surface of the rotating rod; Several protruding blocks are fixedly connected to the outer surface of the transmission belt, and the protruding blocks are evenly distributed with respect to the transmission belt. Among them, several protruding blocks are configured to provide driving force for the movement of the internal parts of the scraping assembly.

[0013] Furthermore, the leveling assembly includes a swing plate rotatably connected inside the main body, with a contact plate fixedly connected to the top of the swing plate; A spring plate is fixedly connected to the bottom of the swing plate, and the side wall of the spring plate is in contact with the outer surface of the contact rod. The top of the contact plate contacts the side wall of the drive belt.

[0014] The present invention has the following beneficial effects: 1. In this invention, the rotation of the rotating rod will drive the surface pushing ring to rotate synchronously. The rotation of the pushing ring will drive the rotating plate to rotate around the connection with the fixed block. Since the pushing rings in the same group are distributed in a cross pattern, the rotating plate will swing left and right continuously under the push of the pushing ring. The wave-shaped setting of the rotating plate ensures that the waterproof membrane at the top of the rotating plate will always be in the center position under the influence of the relative movement of the two rotating plates, thereby reducing the offset of the waterproof membrane during transportation and further improving the accuracy of the coating of the environmentally friendly waterproof tote bag.

[0015] 2. In this invention, the elastic sheet will deform under pressure, and after deformation, it will generate a certain rebound force. When the rotating plate is rotating, the rebound force of the elastic sheet will push the sliding sleeve to slide outward. When the sliding sleeve slides, the convex area at the top of the sliding sleeve will drive the top waterproof membrane to slide outward. Since the sliding sleeve is set at the edge of the waterproof membrane, it reduces the curling of the edge of the waterproof membrane due to the lifting effect of the rotating plate during movement, and further improves the flatness of the waterproof membrane when the environmentally friendly waterproof tote bag is laminated.

[0016] 3. In this invention, because the distance between the rotating plate and the wave bar is relatively large, when the rotating plate rotates, the waterproof membrane between the rotating plate and the wave bar may wrinkle due to the back-and-forth swing of the rotating plate. When the wrinkled area is transported to the extrusion bar for pressing, overlap may occur. The wave bar will rotate under the drive of the waterproof membrane. Due to the spiral protrusion on the wave bar, when the wave bar rotates, it will push open the wrinkles formed by the waterproof membrane, reducing the overlap of the waterproof membrane when the mesh is covered, and further improving the integrity of the coverage when the environmentally friendly waterproof tote bag is covered.

[0017] 4. In this invention, the continuous movement of the protruding block generates a downward squeezing force on the bottom contact plate. The contact plate drives the swing plate to rotate according to the rotation point. The elastic plate moves closer to and contacts the contact rod under the movement of the swing plate. The rotation of the contact rod will cause the contact plate to reset when it is no longer squeezed by the protruding block, so that the movement mode of the swing plate is swinging. The bottom of the swing plate will contact the waterproof membrane. The swinging of the swing plate will reduce the occurrence of grooves when the waterproof membrane is stretched due to the protruding design on the wave rod, and further improve the stability of the waterproof membrane itself when the environmentally friendly waterproof tote bag is laminated.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-8 As shown, the present invention is a laminating device for processing environmentally friendly waterproof tote bags, comprising a main body 1, and further comprising: Correction mechanism 2 is installed inside the main body 1 and is used to correct the waterproof membrane; The correction mechanism 2 includes a fixed plate 201 fixedly connected inside the main body 1. Several fixed blocks 211 are fixedly connected to the top of the fixed plate 201. The several fixed blocks 211 are symmetrically distributed around the main body 1. Anti-folding mechanism 3 is installed on the right side of the correction mechanism 2 to reduce the overlap of the waterproof membrane; There are two fixed blocks 211, which are used to support the movement of the swing assembly 21.

[0024] Entity 1 includes: The coating assembly 11 is disposed inside the main body 1; Auxiliary component 12 is located on the left side of the coating component 11 and is used for winding up the finished fabric.

[0025] Corrective agency 2 also includes: A swing assembly 21 is disposed on top of the film covering assembly 11; The edge-pushing component 22 is disposed on the side wall of the swing component 21 and is used to flatten the curled edge.

[0026] Anti-folding mechanism 3 includes: A leveling component 31 is provided on the right side of the swing component 21. The leveling component 32 is located at the bottom of the leveling component 31 and is used to level the waterproof membrane.

[0027] The coating assembly 11 includes an extrusion rod 111 rotatably connected inside, and a heating rod 112 is provided on the right side of the coating assembly 11; The heating rod 112 is rotatably connected to the interior of the main body 1; The main body 1 has a number of contact rods 113 inside, and the contact rods 113 are distributed at equal intervals around the main body 1; There are five contact rods 113, four of which are located at the bottom of the heating rod 112 and the other is flush with the heating rod 112. After the waterproof membrane is placed, the staff will start the motor inside the device to heat the heating rod 112. At this time, the extrusion rod 111, the heating rod 112 and the contact rod 113 will rotate. The fabric and the waterproof membrane will gradually move towards the placement rod 122 under the rotation and extrusion of the extrusion rod 111 and the bottom contact rod 113.

[0028] The auxiliary component 12 includes a winding rod 121 rotatably connected inside the main body 1, and a placement rod 122 is provided at the bottom of the winding rod 121; The placement rod 122 is rotatably connected to the side wall of the main body 1, and a rotating rod 123 is provided on the top of the placement rod 122; The rotating rod 123 is rotatably connected to the inside of the fixed block 211; The rotating rod 123 is rotatably connected to the inside of the main body 1 at both ends. The heating rod 112 heats the waterproof membrane so that the extrusion rod 111 can better extrude the waterproof membrane and the fabric. At the same time, the placement rod 122 rolls up the fabric after the membrane is coated.

[0029] The swing assembly 21 includes a rotating plate 212 rotatably connected to the top of the fixed block 211; The bottom of the rotating plate 212 is provided with several pushing rings 213, which are arranged in pairs and symmetrically distributed around the main body 1. The push ring 213 is fixedly connected to the outer surface of the rotating rod 123; Among them, there are four push rings 213, and each group of push rings 213 is distributed in a cross pattern. When the push rings 213 move, they will continuously push the rotating plate 212 to rotate. The waterproof membrane will contact the top of the rotating plate 212 and adapt to the shape of the top of the rotating plate 212. When the extrusion rod 111 drives the fabric and the waterproof membrane to move, the waterproof membrane will drive the wave rod 311 to rotate. When the wave rod 311 rotates, it will drive the transmission belt 312 to rotate.

[0030] The pushing edge assembly 22 includes a sliding sleeve 221 that is slidably connected to the surface of the rotating plate 212, and an elastic piece 222 is rotatably connected to the bottom of the sliding sleeve 221; The end of the elastic piece 222 away from the sliding sleeve 221 is rotatably connected to the top of the fixed plate 201. The rotating plate 212 applies downward pressure to the elastic piece 222, and the elastic piece 222 will deform under the influence of the pressure. After the elastic piece 222 deforms, it will generate a certain rebound force. When the rotating plate 212 is in the rotating state, the rebound force of the elastic piece 222 will push the sliding sleeve 221 to slide outward.

[0031] The flattening assembly 31 includes a wave rod 311 rotatably connected inside the main body 1, a transmission belt 312 sleeved on the outer surface of the wave rod 311, and the end of the transmission belt 312 away from the wave rod 311 sleeved on the outer surface of the rotating rod 123. A number of protruding blocks 313 are fixedly connected to the outer surface of the transmission belt 312, and the number of protruding blocks 313 are distributed at equal intervals with respect to the transmission belt 312. Among them, several protruding blocks 313 are configured to provide driving force for the movement of the internal parts of the scraping assembly 32. Due to the spiral protrusion on the wave bar 311, when the wave bar 311 rotates, it will push open the wrinkles formed by the waterproof membrane, reducing the overlap of the waterproof membrane when the mesh is covered.

[0032] The leveling assembly 32 includes a swing plate 321 rotatably connected inside the main body 1, and a contact plate 322 is fixedly connected to the top of the swing plate 321. A spring plate 323 is fixedly connected to the bottom of the swing plate 321, and the side wall of the spring plate 323 is in contact with the outer surface of the contact rod 113. The top of the contact plate 322 contacts the side wall of the transmission belt 312, and the transmission belt 312 will move periodically. At this time, the protruding block 313 on the transmission belt 312 will move synchronously. The continuous movement of the protruding block 313 will exert a downward squeezing force on the bottom contact plate 322, and the contact plate 322 will drive the swing plate 321 to rotate according to the rotation point.

[0033] In use, the operator first places the rolled waterproof membrane on the rotating rod 123, then pulls the waterproof membrane to the wave rod 311 and makes contact. Next, the waterproof membrane is passed between the extrusion rod 111 and the contact rod 113. After the waterproof membrane is placed, the operator starts the motor inside the device and heats the heating rod 112. At this time, the extrusion rod 111, the heating rod 112 and the contact rod 113 rotate. The fabric and the waterproof membrane will gradually move towards the placement rod 122 under the rotation and extrusion of the extrusion rod 111 and the bottom contact rod 113. The heating rod 112 heats the waterproof membrane so that the extrusion rod 111 can better extrude the waterproof membrane and the fabric. At the same time, the placement rod 122 rolls up the coated fabric, thus completing the coating process of the environmentally friendly waterproof tote bag fabric.

[0034] When the device is started, the waterproof membrane comes into contact with the top of the rotating plate 212 and adapts to the shape of the top of the rotating plate 212. When the squeezing rod 111 moves the fabric and the waterproof membrane, the waterproof membrane drives the wave rod 311 to rotate. When the wave rod 311 rotates, it drives the transmission belt 312 to rotate. The movement of the transmission belt 312 drives the rotating rod 123 to rotate. The rotation of the rotating rod 123 drives the push ring 213 on the surface to rotate synchronously. The rotation of the push ring 213 drives the rotating plate 212 to rotate around the connection with the fixed block 211. Since the push rings 213 in the same group are crisscrossed, the rotating plate 212 will swing left and right continuously under the push of the push rings 213. The wave shape of the rotating plate 212 ensures that the waterproof membrane at the top of the rotating plate 212 is always in the center position under the influence of the relative movement of the two rotating plates 212, thereby reducing the offset of the waterproof membrane during transportation and further improving the accuracy of the environmentally friendly waterproof tote bag in the film coating process.

[0035] When the rotating plate 212 is pushed outward by the push ring 213, the rotating plate 212 will apply downward pressure to the elastic sheet 222. The elastic sheet 222 will deform under the influence of the pressure, and after the elastic sheet 222 deforms, it will generate a certain rebound force. When the rotating plate 212 is rotating, the rebound force of the elastic sheet 222 will push the sliding sleeve 221 to slide outward. When the sliding sleeve 221 slides, the convex area at the top of the sliding sleeve 221 will drive the top waterproof membrane to slide outward. Since the sliding sleeve 221 is set at the edge of the waterproof membrane, the edge of the waterproof membrane is reduced from curling due to the lifting effect of the rotating plate 212 during movement, which further improves the flatness of the waterproof membrane when the environmentally friendly waterproof tote bag is laminated.

[0036] When the rotating plate 212 swings left and right, due to the large distance between the rotating plate 212 and the wave rod 311, the waterproof membrane between the rotating plate 212 and the wave rod 311 may wrinkle as the rotating plate 212 swings back and forth. When the wrinkled area is transported to the pressing rod 111 for pressing, it may overlap. The wave rod 311 will rotate under the drive of the waterproof membrane. Due to the spiral protrusion on the wave rod 311, when the wave rod 311 rotates, it will push open the wrinkles formed by the waterproof membrane, reducing the overlap of the waterproof membrane when the mesh is covered, and further improving the integrity of the coverage when the environmentally friendly waterproof tote bag is covered.

[0037] When the wave bar 311 rotates, the transmission belt 312 will move periodically. At this time, the protruding block 313 on the transmission belt 312 will move synchronously. The continuous movement of the protruding block 313 will exert a downward squeezing force on the bottom contact plate 322. The contact plate 322 will drive the swing plate 321 to rotate according to the rotation point. The elastic plate 323 will approach and contact the contact bar 113 under the movement of the swing plate 321. The rotation of the contact bar 113 will cause the contact plate 322 to reset when it is no longer squeezed by the protruding block 313, so that the movement mode of the swing plate 321 is swinging. The bottom of the swing plate 321 will contact the waterproof membrane. The swing of the swing plate 321 will reduce the occurrence of grooves when the waterproof membrane is stretched due to the protruding design on the wave bar 311, and further improve the stability of the waterproof membrane itself when the environmentally friendly waterproof tote bag is laminated.
