Description

Technical Field

[0001] This utility model relates to the field of electroplated aluminum adhesive production technology, specifically to an electroplated aluminum adhesive production equipment. Background Technology

[0002] Adhesive backing for electroplated aluminum foil is a key component of electroplated aluminum hot stamping foil. During the hot stamping process, when the stamped area is heated, the adhesive backing melts, causing the aluminum plating layer and coloring layer of the electroplated aluminum foil to adhere tightly to the surface of the hot stamping substrate. This allows the transfer of electroplated aluminum patterns or text onto the substrate. In the production process of electroplated aluminum adhesive backing, comma-shaped scrapers, micro-gravure rollers, or slit coating heads are commonly used to evenly coat the adhesive backing onto the release layer surface of the PET base film, completing the coating process.

[0003] The existing technology has the following problems:

[0004] In the existing process of making electroplated aluminum adhesive, the formulated adhesive needs to be applied to the surface of PET base film or other products. However, the existing coating equipment cannot make the product and the coating roller adhere tightly while conveying products of different thicknesses, resulting in uneven adhesive application and low automation and production efficiency. Utility Model Content

[0010] Preferably, the conveying assembly includes two conveying cylinders, each with a sliding rod fixedly connected to its front and rear ends. A supporting connecting rod is rotatably connected to the outer surface of the sliding rod, and a supporting extrusion cylinder is rotatably connected to the end of the supporting connecting rod away from the conveying cylinder. A conveyor belt is movably connected to the outer surfaces of the supporting extrusion cylinder and the two conveying cylinders.

[0011] Preferably, the ends of the two supporting rods located on the same front and rear sides that are away from the conveying cylinder are rotatably connected to each other, and the two supporting rods on the same left and right sides are fixedly connected to the opposite sides of the connecting rods, and the two connecting rods are connected to a traction spring.

[0012] Preferably, the sliding rod can enter and be movably connected to the inside of the nearest moving slot, and the output shaft of the conveying motor can be fixedly connected to the rear end of the left conveying cylinder through the moving slot.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: an electroplated aluminum backing adhesive production equipment, including a coating hopper 1, with support frames 2 on both the front and rear sides of the coating hopper 1, and a conveying component 3 is provided in the middle of the opposite sides of the two support frames 2, with the top center of the conveying component 3 located below the bottom of the coating hopper 1.

[0023] During operation, the PET base film and other products to be coated are carried and conveyed forward by the conveying component 3. When the product moves to the bottom of the coating hopper 1, the adhesive in the coating hopper 1 is applied to the product surface through the bottom coating structure, realizing continuous operation of coating while conveying.

[0024] Please see Figure 2 The paint hopper 1 includes a storage hopper 12, with a feed pipe 11 fixedly connected to the top of the storage hopper 12. A coating roller 14 is rotatably connected to the bottom inner side of the storage hopper 12. The lower side of the outer surface of the coating roller 14 is located outside the bottom of the storage hopper 12. Several paint grooves 13 are opened on the outer surface of the coating roller 14.

[0025] The adhesive is injected into the storage hopper 12 through the feed pipe 11. When the coating roller 14 rotates, the coating tank 13 on the outer surface scoops the adhesive from the storage hopper 12 and rotates with the roller to the outside of the storage hopper 12. Through the contact or gap between the coating roller 14 and the product surface, the adhesive is evenly applied to the product surface above the conveying assembly 3.

[0026] Please see Figure 3 The support frame 2 includes two support bodies 24, which are fixedly connected to the front and rear ends of the storage hopper 12 respectively. The support bodies 24 have moving slots 23 extending through them.

[0027] Please see Figure 3The rear support body 24 has sliding grooves 22 on the upper and lower sides of the moving groove 23, and the inner sides of the two sliding grooves 22 are slidably connected to the conveying motor 21.

[0028] Two support bodies 24 support the paint hopper 1, and a moving trough 23 runs through the front and back, providing space for the conveying assembly 3 to move. The conveying motor 21 is installed on the support body 24 through the sliding groove 22 and can slide horizontally. During operation, the conveying motor 21 drives the conveying assembly 3 to operate through the output shaft. At the same time, it can adjust its position by sliding horizontally in the sliding groove 22 according to the product thickness or tension requirements, so as to realize the dynamic adjustment of the running height or tension of the conveying assembly 3.

[0029] Please see Figure 4 The conveying assembly 3 includes two conveying cylinders 32. Sliding rods 33 are fixedly connected to the front and rear ends of the conveying cylinders 32. Supporting rods 34 are rotatably connected to the outer surface of the sliding rods 33. Supporting extrusion cylinders 35 are rotatably connected to the end of the supporting rods 34 away from the conveying cylinders 32. Conveyor belts 31 are movably connected to the outer surfaces of the supporting extrusion cylinders 35 and the two conveying cylinders 32.

[0030] Please see Figure 4 Two supporting rods 34 located on the same side at the front and back are rotatably connected at the ends away from the conveying cylinder 32. Two supporting rods 34 on the same side at the left and right are fixedly connected to the opposite sides of the connecting rods 34. The two connecting rods 37 are connected to a traction spring 36.

[0031] Please see Figures 3-4 The sliding rod 33 can enter and be movably connected to the inside of the nearest moving groove 23, and the output shaft of the conveying motor 21 can be fixedly connected to the rear end of the left conveying cylinder 32 through the moving groove 23.

[0032] The conveyor motor 21 drives the left conveyor cylinder 32 to rotate, which in turn drives the right conveyor cylinder 32 to rotate synchronously through the conveyor belt 31, forming the power for product conveying. The tension of the conveyor belt 31 is maintained by the support rod 34 and the support extrusion cylinder 35 to ensure smooth product conveying. When the product thickness changes, the support extrusion cylinder 35 floats up and down with the product thickness. The traction spring 36 automatically adjusts the tension of the conveyor belt 31 and the bonding pressure between the product and the coating roller 14 through the linkage structure to achieve adaptive adjustment.

[0033] Please see Figures 1-4 At work,

[0034] First, the adhesive is injected into the storage hopper 12 through the feed pipe 11, so that the coating roller 14 is partially immersed in the adhesive. The PET base film product to be coated is placed on the conveyor belt 31. The conveyor motor 21 is started, and the conveyor cylinder 32 is driven to rotate through the output shaft, which drives the conveyor belt 31 to transport the product forward. The coating roller 14 rotates synchronously with the product transport. After the coating tank 13 on its surface scoops up the adhesive, it is evenly coated on the product surface through contact or gap with the product surface. When the product thickness changes, the support extrusion cylinder 35 drives the sliding rod 33 to slide horizontally in the moving groove 23 through the support connecting rod 34. The traction spring 36 automatically adjusts the tension of the conveyor belt 31 and the adhesion pressure between the product and the coating roller 14 through elastic force to ensure uniform coating.
