Description

Technical Field

[0001] The utility model relates to the technical field of coating mechanisms, in particular to a colloid coating mechanism for paper products. Background Art

[0002] Paper products refer to paper products made from paper and cardboard as raw materials and further processed. In order to increase the strength and printability of paper products, a layer of colloid needs to be applied to the surface of the paper products.

[0003] When using an existing colloid coating mechanism, the paper product is generally transported to the bottom of the gluing mechanism through a conveying mechanism, and then glue is applied by the gluing mechanism. However, the gluing mechanism generally transports the colloid through a glue discharge head to the surface of the gluing roller, and then the gluing roller applies the colloid to the surface of the paper product. Since the colloid transported by the glue discharge head to the surface of the gluing roller cannot evenly adhere to the surface of the gluing roller, the colloid on the surface of the gluing roller cannot be evenly applied to the paper product, resulting in poor gluing effect. In addition, it is generally necessary to heat the paper product after gluing to accelerate the solidification of the colloid. However, the existing drying mechanism generally accelerates the solidification of the colloid by spraying hot air onto the surface of the paper product through an air pump. This causes the colloid to flow due to the blowing of the hot air, which in turn leads to uneven colloid on the surface of the paper product and poor use effect. For this reason, we propose a colloid coating mechanism for paper products. Utility Model Content

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-Figure 5 A paper product colloid coating mechanism includes a base 1, a control box 27 is installed on one side of the base 1, and a controller is provided in the control box 27. The controller is a control mainboard or a host.

[0030] Two strip-shaped mounting plates 23 are symmetrically installed on the top of the base 1, and a number of conveying rollers 5 are rotatably connected between the two strip-shaped mounting plates 23. The conveying rollers 5 are connected to a driving mechanism. The driving mechanism includes sprockets installed at both ends of the conveying rollers 5. The sprockets on two adjacent conveying rollers 5 are connected by a chain. A driving motor 24 is installed at one end of one of the conveying rollers 5. The driving motor 24 is fixed on the base 1. The driving motor 24 is connected to the controller through a wire. During actual use, the staff places the smeared paper product on the conveying roller 5. The driving motor 24 can drive the conveying roller 5 to rotate through the sprocket and chain to convey the paper product.

[0031] like Figure 1 and Figure 2 As shown, a U-shaped frame 2 is installed on the top of the base 1, and a U-shaped fixing plate 15 is provided inside the U-shaped frame 2, and both ends of the U-shaped frame 2 are connected to the U-shaped frame 2 through an adjusting mechanism. The adjusting mechanism includes a through slot 3 opened on both sides of the U-shaped frame 2, and connecting blocks 12 are installed on both ends of the U-shaped fixing plate 15. One end of each connecting block 12 passes through the corresponding through slot 3, and the two sides of the connecting block 12 are slidably connected to the guide rails fixed on both sides of the through slot 3 through sliders. Fixed blocks 8 are installed on both sides of the U-shaped frame 2, and a telescopic mechanism 17 is installed at the bottom of the fixed block 8. The bottom of each telescopic mechanism 17 is fixed to the top of the corresponding connecting block 12. The telescopic mechanism 17 is one of an electric push rod, a cylinder or a hydraulic rod. The telescopic mechanism 17 is connected to the controller through a wire. In actual use, the staff can drive the U-shaped fixing plate 15 up and down through the telescopic mechanism 17, and the position of the U-shaped fixing plate 15 can be adjusted according to the thickness of the paper product.

[0032] like Figure 1 and Figure 3 As shown, the internal rotation of the U-shaped fixed plate 15 is connected to the glue coating roller 6, which is located above the conveying roller 5 and is aligned with one of the conveying rollers 5. A glue storage box 4 is installed on the top of the U-shaped frame 2, and a number of glue discharge heads 7 are installed at equal intervals on the bottom of the glue storage box 4. Each glue discharge head 7 is fixed on the U-shaped fixed plate 15, and the end of each glue discharge head 7 is located above the glue coating roller 6. During actual use, the glue discharge head 7 can transport the glue in the glue storage box 4 to the surface of the glue coating roller 6, and at the same time, the bottom of the glue coating roller 6 will contact the top of the paper product conveyed by the conveying roller 5, so that the glue coating roller 6 will rotate with the movement of the paper product, and at the same time, the glue on the glue coating roller 6 will be smeared on the surface of the paper product.

[0033] like Figure 2 and Figure 3As shown, at least one mounting plate 14 is installed on one side of the U-shaped fixing plate 15, and a scraper 13 is provided at the bottom of the mounting plate 14. One end of the scraper 13 is fixed to the bottom surface of the mounting plate 14 through a strip connecting plate 25, and the other end of the scraper 13 is in clearance with the side of the glue roller 6. In actual use, while the glue roller 6 rotates with the paper product, one end of the scraper 13 will move relative to the side of the glue roller 6, so that the glue delivered to the glue roller 6 by the glue head 7 will be evenly spread by the scraper 13, which will make the glue coating of the glue roller 6 more uniform.

[0034] It should be noted that if Figure 3 As shown, both sides of the glue coating roller 6 extend to the outside of the U-shaped fixing plate 15, so that the U-shaped fixing plate 15 does not hinder the scraper 13, so that one end of the scraper 13 can fully contact the side of the glue coating roller 6.

[0035] like Figure 1 and Figure 5 As shown, a drying cover 9 with openings at both ends is installed on the top of the base 1, a mounting groove 18 is provided on the top of the inner portion of the drying cover 9, and a first heating resistance wire 21 is provided inside the mounting groove 18. The interior of the drying cover 9 can be heated by the first heating resistance wire 21. After the glued paper product is transported into the drying cover 9, the solidification of the colloid can be accelerated under the action of the first heating resistance wire 21.

[0036] like Figure 4 As shown, a heating hood 20 is provided between the two strip mounting plates 23. The heating hood 20 is located inside the drying hood 9. A heating chamber 19 is provided inside the heating hood 20. A second heating resistance wire 26 is installed inside the heating chamber 19. A plurality of receiving grooves 22 are provided on the top of the heating hood 20. The bottom end of the conveying roller 5 is located in the corresponding receiving groove 22. The receiving groove 22 is connected to the heating chamber 19, and the bottom of the conveying roller 5 passes through the receiving groove 22 and is located inside the heating chamber 19. In actual use, the second heating resistance wire 26 can heat the inside of the heating chamber 19, and then heat the conveying roller 5. The conveying roller 5 will heat the bottom of the paper product in the process of conveying the paper product, which can further increase the solidification speed of the colloid and improve the use effect.

[0037] It should be noted that the first heating resistor 21 and the second heating resistor 26 are both connected to the controller via wires. The controller can control the operation of the first heating resistor 21 and the second heating resistor 26, which is convenient to control.

[0038] Specifically, when the present invention is in use, the staff places the paper product to be glued on the conveying roller 5, and the controller controls the driving motor 24 to drive the conveying roller 5 to rotate, and the conveying roller 5 conveys the paper product to the inside of the U-shaped frame 2. At the same time, the controller controls the telescopic mechanism 17 to work, and the telescopic mechanism 17 drives the U-shaped fixed plate 15 to move, and adjusts the glue roller 6 to a preset height. When the paper product moves below the glue roller 6, the bottom of the glue roller 6 contacts the paper product, and at the same time, the glue head 7 conveys the glue in the glue storage box 4 to the surface of the glue roller 6. The paper product follows the conveying roller 5. While moving, the glue coating roller 6 will be driven to rotate, so that the scraper 13 will move relative to the side of the glue coating roller 6, and the glue delivered to the surface of the glue coating roller 6 by the glue head 7 will be spread evenly. Then the glue coating roller 6 will evenly apply the spread glue on the surface of the paper product. The coated paper product is transported to the drying cover 9 under the action of the conveying roller 5. At the same time, the controller controls the first heating resistor wire 21 and the second heating resistor wire 26 to work, heating the upper and lower sides of the paper product to accelerate the solidification speed of the colloid. The dried paper product is moved out of the drying cover 9 through the conveying roller 5.

[0039] Furthermore, if Figure 1 and Figure 3 As shown, the scraper 13 is arranged in a "U" shape, and open grooves 16 are provided on both sides of the U-shaped frame 2. Both ends of the scraper 13 pass through the open grooves 16. Support plates 10 are installed on both sides of the base 1. A collecting bucket 11 is installed on the top of each support plate 10. The collecting bucket 11 is located below the scraper 13. A channel for the flow of colloid is formed on the top of the scraper 13. In this way, when the scraper 13 spreads the colloid on the glue roller 6, the excess glue will flow along the channel on the top of the scraper 13 to the collecting bucket 11 for collection.

[0040] Furthermore, if Figure 4 and Figure 5 As shown, the first heating resistance wire 21 and the second heating resistance wire 26 are both arranged in an "S" shape or a serpentine shape, which increases the heating area of the first heating resistance wire 21 and the second heating resistance wire 26 and improves the drying effect.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
