Description

Technical Field

[0001] This utility model relates to the field of packaging bag production, and in particular to a solvent-free laminating machine for packaging bag production. Background Technology

[0002] Solvent-free laminating machines are a type of equipment used to produce packaging bags. They offer numerous advantages, including: strong environmental performance (no solvents are used in the production process, avoiding pollution to the environment and worker health); high production efficiency (the equipment is high-speed and efficient, far exceeding the production efficiency of traditional laminating machines); low production cost (due to the elimination of solvent purchase and use, compact design, small footprint); and high product quality (the use of advanced control systems and high-quality composite materials brings significant convenience to the production and processing of packaging bags).

[0003] Existing solventless laminating machines typically have mounting mechanisms that can only secure cooling rollers of a specific size. Different mounting mechanisms are required for different sizes of cooling rollers, causing significant inconvenience for operators. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a solvent-free laminating machine for packaging bag production, which has the advantage of being able to install cooling rollers of different sizes.

[0005] The technical solution of this utility model is:

[0006] A solvent-free laminating machine for packaging bag production includes a laminating machine body. The upper end of the laminating machine body has multiple sliding grooves. A slider is slidably connected inside the sliding groove. A pair of vertical plates are fixedly connected to the upper end of the slider. A mounting plate is rotatably connected between the pair of vertical plates via a rotating shaft. The mounting plate has multiple mounting slots of different sizes. A limit block is fixedly connected to the end of one of the vertical plates away from the mounting plate. A threaded tube is threadedly connected inside the limit block. The side end of the mounting plate has multiple mating slots for movably inserting the threaded tube.

[0007] The working principle of the above technical solution is as follows: rotate the mounting plate, select a suitable mounting groove, insert the mounting end of the cooling roller into the mounting groove, then put the mounting plate on the mounting end of the cooling roller, and finally move the lower block to fix the slider to prevent the pair of mounting plates from separating.

[0008] A limiting groove is provided on the side end of the vertical plate, and a moving block is slidably connected inside the limiting groove. A pair of rectangular grooves are provided on the inner bottom wall of the sliding groove, which are movably inserted with the moving block.

[0009] The lower moving block is inserted into the limiting groove to fix the slider, thereby fixing the mounting plate in a fixed position, which solves the technical problem in the prior art that a pair of mounting plates are easily separated from the mounting end of the cooling roller.

[0010] In a further technical solution, a reinforcing groove is provided on each of the two inner sidewalls of the limiting groove, and a reinforcing block is fixedly connected to each of the two side ends of the moving block and is slidably connected to the reinforcing groove.

[0011] When the moving block moves, the reinforcing block can prevent the moving block from moving out of the limiting groove, which solves the technical problem of unstable up and down movement of the moving block in the prior art.

[0012] In a further technical solution, one end of the threaded tube is movably inserted into the inside of the mating groove, and the other end of the threaded tube passes through the limiting block and extends to the outside.

[0013] After one end of the threaded tube is installed in the mating groove, the mounting plate can be fixed, which solves the technical problem that the mounting plate is easy to rotate in the prior art. After one end of the threaded tube is installed in the mating groove, the other end of the threaded tube extends out from the limiting block. Since the other end of the threaded tube extends out from the limiting block, it is easy for personnel to hold the threaded tube and apply force to it, thus making it easier for personnel to install and remove the threaded tube.

[0014] In a further technical solution, sidewall grooves are provided on both inner sidewalls of the slide, and sidewall blocks that are slidably connected to the sidewall grooves are fixedly connected to both side ends of the slider.

[0015] When the slider moves, it will drive the side wall block, causing the side wall block to move together in the side wall groove. The side wall block can be used to limit the slider and prevent it from moving upward. This can prevent the vertical plate and mounting plate from moving upward and separating from the composite machine body, thus solving the technical problem in the prior art that the slider is more likely to move out of the groove when it is under force.

[0016] In a further technical solution, a storage slot is provided on the inner bottom wall of the composite machine body, a sealing plate is movably inserted inside the storage slot, a telescopic spring is fixedly connected to the inner side wall of the storage slot, a soft rubber plate is fixedly connected to the side end of the telescopic spring, and a sponge plate is fixedly connected to the end of the soft rubber plate away from the telescopic spring.

[0017] When the surface of the cooling roller needs cleaning, simply remove the soft rubber plate and sponge plate from the storage slot to stretch the telescopic spring. Then apply force to the soft rubber plate and sponge plate so that the side end of the sponge plate contacts the outer end of the cooling roller. Then move the sponge plate so that it moves on the cooling roller and rubs against the outer end of the cooling roller to wipe away impurities and dust. This makes it easy for personnel to clean the surface of the cooling roller.

[0018] In a further technical solution, a baffle is fixedly connected to the inner wall of the storage tank, a magnetic coating is applied to the outer end of the sealing plate, a magnetic coating is applied to the inner wall of the storage tank, and a handle is fixedly connected to the side end of the sealing plate. In the initial state, the side end of the sealing plate is in contact with the baffle.

[0019] By utilizing magnetic coating one and magnetic coating two, the stability of the sealing plate in the storage tank can be improved, solving the technical problem in the prior art that the sealing plate is easily removed from the storage tank.

[0020] The beneficial effects of this utility model are:

[0021] 1. With the installation plate and slider, when installing cooling rollers of different sizes, the operator only needs to rotate the installation plate, select the installation groove that matches the cooling roller, and then move the slider to install the installation plate onto the cooling roller. This composite machine makes it easy for operators to install cooling rollers of different sizes and the operation steps are simple, making it convenient for operators to install cooling rollers.

[0022] 2. The sponge board and soft rubber board are designed so that users can remove them from the storage tank and then wipe the surface of the cooling roller with them, thereby cleaning the surface of the cooling roller and improving its cleanliness. Attached Figure Description

[0032] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0033] Example:

[0034] like Figure 1 - Figure 5 and Figure 7 As shown, a solventless laminating machine for packaging bag production includes a laminating machine body 1. The upper end of the laminating machine body 1 is provided with multiple sliding grooves 2. A slider 3 is slidably connected inside the sliding grooves 2. A pair of vertical plates 4 are fixedly connected to the upper end of the slider 3. A mounting plate 5 is rotatably connected between the pair of vertical plates 4 via a rotating shaft. The mounting plate 5 is provided with multiple mounting grooves 6 of different sizes. A limiting block 7 is fixedly connected to the end of one of the vertical plates 4 away from the mounting plate 5. A threaded tube 8 is threadedly connected inside the limiting block 7. The side end of the mounting plate 5 is provided with multiple mating grooves 9 that are movably inserted into the threaded tube 8.

[0035] A limiting groove 10 is provided on the side end of the vertical plate 4. A moving block 11 is slidably connected inside the limiting groove 10. A pair of rectangular grooves 12 are provided on the inner bottom wall of the slide groove 2, which are movably inserted into the moving block 11. A pair of reinforcing grooves 13 are provided on the inner side walls of the limiting groove 10. A pair of reinforcing blocks 14 are fixedly connected to the side ends of the moving block 11 and slidably connected to the reinforcing grooves 13. When the moving block 11 moves, the reinforcing blocks 14 can limit the moving block 11, making it difficult for it to separate from the vertical plate 4. One end of the threaded tube 8 is movably inserted into the docking groove 9. The other end of the threaded tube 8 passes through the limiting block 7 and extends to the outside. A pair of side wall grooves 15 are provided on the inner side walls of the slide groove 2. A pair of side wall blocks 16 are fixedly connected to the side ends of the slider 3 and slidably connected to the side wall grooves 15. When the slider 3 moves, the side wall blocks 16 can limit the slider 3 and prevent the slider 3 from moving out of the slide groove 2.

[0036] The working principle of the above technical solution is as follows:

[0037] Step 1: Installation. When installing the cooling roller, rotate the mounting plate 5 according to the outer diameter of the connectors at both ends of the cooling roller, and select the mounting groove 6 that matches the size on the mounting plate 5. After selecting the mounting groove 6, install the threaded tube 8 into the mating groove 9 to fix the mounting plate 5. Then move the slider 3 to align the selected pair of opposite mounting grooves 6, thus forming a circle that fits the cooling roller. Then insert both ends of the cooling roller into the circular groove formed by the pair of mounting grooves 6. Then push the moving block 11 downward so that the lower end of the moving block 11 is inserted into the rectangular groove 12 to fix the slider 3, and then install and fix the mounting plate 5 on the outer end of the cooling roller (in conjunction with...). Figure 1 As shown in the figure, this composite machine is easy for personnel to install cooling rollers of different sizes and models. The installation steps are simple and easy for personnel to use.

[0038] Step 2: Disassembly. When removing the cooling roller for replacement or repair, simply remove the moving block 11 from the rectangular groove 12, keeping a certain distance between the pair of opposing sliders 3 so that the mounting plate 5 is separated from the cooling roller. Finally, remove the cooling roller for replacement or repair. This improves the convenience of personnel when inspecting and replacing the cooling roller, and the cleaning steps are simple and easy for personnel to use.

[0039] After cleaning the cooling rollers, simply move the soft rubber plate.

[0040] In another embodiment, such as Figure 5-6 As shown, a storage slot 17 is provided on the inner bottom wall of the composite machine body 1. A sealing plate 18 is movably inserted inside the storage slot 17. A telescopic spring 19 is fixedly connected to the inner side wall of the storage slot 17. A soft rubber plate 20 is fixedly connected to the side end of the telescopic spring 19. A sponge plate 21 is fixedly connected to the end of the soft rubber plate 20 away from the telescopic spring 19.

[0041] A baffle 22 is fixedly connected to the inner wall of the storage slot 17. The baffle 22 allows the side end of the sealing plate 18 to be flush with the side end of the storage slot 17. The outer end of the sealing plate 18 is coated with a magnetic coating 23, and the inner wall of the storage slot 17 is coated with a magnetic coating 24. After the magnetic coating 23 and the magnetic coating 24 are attracted together, the stability of the sealing plate 18 in the storage slot 17 can be improved. A handle is fixedly connected to the side end of the sealing plate 18. In the initial state, the side end of the sealing plate 18 is in contact with the baffle 22.

[0042] When in use, the sealing plate 18 can be removed from the storage groove 17, the sponge plate 21 and the soft rubber plate 20 can be pulled to pull the telescopic spring 19 and move out of the storage groove 17, and then the sponge plate 21 and the soft rubber plate 20 can be bent to move on the cooling roller to wipe away the impurities adhering to the cooling roller, thereby cleaning the cooling roller and keeping the surface of the cooling roller clean.

[0043] After cleaning the cooling roller, the soft rubber plate 20 needs to be moved. Under the tension of the telescopic spring 19, the soft rubber plate 20 will pull the sponge plate 21 into the storage tank 17 together until the soft rubber plate 20 and the sponge plate 21 are moved into the storage tank 17. Finally, the sealing plate 18 is inserted into the storage tank 17 to seal the storage tank 17, thereby protecting the sponge plate 21 from dust and making it less susceptible to dust contamination. At the same time, the magnetic coating 1 23 will come into contact with and be attracted to the magnetic coating 24, making it difficult for the sealing plate 18 to be moved out of the storage tank 17.

[0044] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
