Description

Technical Field

[0001] The utility model relates to the technical field of kraft paper packing machines, and more specifically, to a water spraying device for a kraft paper packing machine. Background Art

[0002] In the modern logistics and packaging industries, efficient and reliable packaging methods are crucial for the storage, transportation, and protection of items. As a widely used packaging material, kraft paper has the advantages of high strength, good toughness, and recyclability. When packing, the items to be packed are first stacked, then the stack of books is wrapped with cut kraft paper, the sides are sealed, then the two sides are folded and sealed, and finally, it is packed with a packing machine.

[0003] However, the existing kraft paper packing machines have the following problems when in use:

[0004] Although kraft paper is known for its toughness and durability, it faces some practical problems in packing applications. Its relatively hard texture makes it difficult for the folded parts to fit tightly during the packing process, which means that there are likely to be gaps in the packed package, and these gaps will greatly affect the firmness of the package. Once the package is not firm, the items inside are likely to scatter out, which may cause damage and loss of items during the logistics transportation process, bringing unnecessary losses to enterprises and consumers. For some items with high packaging requirements, such as precision instruments and electronic products, the risks brought by loose packing of kraft paper are more prominent.

[0005] The utility model can make an appropriate amount of water moisten the kraft paper, make the kraft paper fibers softer, so that it is easier to shape during packing, make the sealing more tight, ensure that the packed package is more compact and firm, and also make the kraft paper smoother when folding and wrapping items, greatly improving the packing efficiency and aesthetics.

[0014] Beneficial effects:

[0015] 1. By providing a solenoid valve and a flow meter, the solenoid valve can quickly open and close the water flow channel according to actual needs, and the flow meter can monitor the water flow rate in real time. According to kraft papers of different materials and thicknesses, operators can flexibly adjust the opening degree of the solenoid valve based on the data displayed by the flow meter. For kraft papers with strong water absorption, the water volume can be appropriately increased; while for kraft papers with thinner texture and prone to excessive wetting, the water volume can be reduced. Such precise adjustment ensures that the kraft paper can obtain an appropriate degree of wetness during the packing process, neither affecting the folding and fitting effects due to too little water volume nor causing the kraft paper to become too soft due to too much water volume, thus affecting the firmness of the packing.

[0016] 2. By providing jacks and a moving block, the setting of the jacks provides multiple installation position options for the moving block, which enables operators to flexibly adjust the height of the moving block according to the thickness of different kraft papers. When facing thicker kraft papers, the moving block can be installed in the jacks at a lower position to ensure that the scraper can better contact the surface of the kraft paper and effectively scrape off the excess water. For thinner kraft papers, the jacks at a higher position can be selected to avoid the scraper applying too much pressure on the kraft paper and damaging the paper.

[0017] 3. In summary, for the water - wetting device of this kraft paper packing machine, by setting up structures such as solenoid valves, flow meters, connecting blocks, moving blocks, and scrapers, according to kraft papers of different materials and thicknesses, operators can flexibly adjust the opening degree of the solenoid valve based on the data displayed by the flow meter to achieve the best wetting effect. This ensures that during the packing process, the kraft paper will neither become soft due to excessive moisture, affecting its firmness, nor be difficult to fold and fit due to insufficient moisture. In subsequent operations, the moving block can flexibly adjust its height between the connecting blocks, enabling the scraper and the scraping strip at its bottom to effectively scrape off the excess water on the kraft paper, ensuring an appropriate water volume. At the same time, the scraping strip can also make the water more evenly distributed on the kraft paper, further enhancing the wetting effect and providing good conditions for the subsequent packing process.

[0024] Please refer to Figures 1-4, in the embodiment of the present utility model, a water-dipping device for a kraft paper packing machine includes: a baffle 1, a fixed table 2 is arranged in the middle of the baffle 1, a water outlet pipe 3 is arranged above the fixed table 2, connecting blocks 4 are threadedly connected to the front and rear of the upper right end of the baffle 1, a moving block 5 is embedded and installed between the connecting blocks 4, there are two baffles 1 front and rear, a conveyor belt 102 is rotatably installed between the baffles 1, a water tank 201 is fixedly installed at the upper end of the fixed table 2, fixed ends 401 are arranged at the bottoms of the left and right ends of the connecting block 4, and the connecting block 4 is threadedly connected to the baffle 1 through the fixed end 401. Support legs 101 are fixedly installed on the left and right sides of the bottom of the baffle 1. The conveyor belt 102 passes through the bottom of the fixed table 2. A water inlet pipe 202 is fixedly installed at the upper end of the water tank 201. Water outlet pipes 3 are fixedly installed on the front and rear sides of the right end of the water tank 201. The fixed end 401 is threadedly connected to the baffle 1 through a screw hole 402. The conveyor belt 102 is installed between the two baffles 1, and then the fixed table 2 is installed at the middle position of the baffle 1. The front end of the fixed table 2 is at the front end of the baffle 1, and the bottom of the fixed table 2 is located above the baffle 1, so that the conveyor belt 102 passes through the bottom of the fixed table 2. Then the water tank 201 is installed at the upper end of the fixed table 2, and the water inlet pipe 202 and the water outlet pipe 3 are installed. Then the connecting block 4 and the moving block 5 are spliced and installed on the right side of the baffle 1. When using this device to dip water on kraft paper, when the kraft paper is placed on the conveyor belt 102, the conveyor belt 102 starts to operate, and the kraft paper is conveyed under the fixed table 2. The water in the water tank 201 is sprayed onto the kraft paper through the water outlet pipe 3 to moisten the kraft paper. Moreover, the water output sprayed by the water outlet pipe 3 can be adjusted according to the thickness of the kraft paper. Then the kraft paper continues to move to the right. When passing under the moving block 5, the height of the moving block 5 can be adjusted according to the thickness of the kraft paper. The bottom of the moving block 5 can scrape off the excess water on the kraft paper to ensure that the kraft paper has an appropriate degree of moisture. The kraft paper after the moisture treatment is easier to fold and fit during the packing process, thereby improving the firmness and aesthetics of the packing.

[0025] In the embodiment of the present utility model, a solenoid valve 301 is provided in the middle of the water outlet pipe 3. A flow meter 302 is provided below the solenoid valve 301. A nozzle 303 is fixedly installed at the outlet of the water outlet pipe 3. During the wetting process of kraft paper, the water in the water tank 201 enters the interior of the water outlet pipe 3. When it is necessary to wet the kraft paper, the solenoid valve 301 is opened to allow water to flow downward through the water outlet pipe. When spraying water is not required, the solenoid valve 301 is closed, effectively avoiding waste of water resources. The flow meter 302 provided below the solenoid valve 301 can monitor the flow rate of water in real time. Through the accurate measurement of the flow meter 302, the operator can accurately know the amount of water sprayed onto the kraft paper, so as to make reasonable adjustments according to kraft paper of different materials and thicknesses, and release the water volume reasonably by adjusting the opening degree of the solenoid valve 301. When it is found that the water volume is too large, the opening degree of the solenoid valve 301 can be appropriately reduced to reduce the water flow through volume, thereby avoiding excessive wetting of the kraft paper and affecting the packing quality. On the contrary, if the water volume is too small and cannot meet the wetting requirements of the kraft paper, the operator can increase the opening degree of the solenoid valve 301 to increase the water spray volume, flexibly adapting to kraft paper of various different materials and thicknesses, and at the same time reducing waste of water resources.

[0026] In the embodiment of the present utility model, a plurality of jacks 403 are equidistantly arranged on the inner side surface of the connecting block 4, screw holes 402 are arranged on the front and rear sides of the upper end of the fixed end 401. The connecting block 4 is embedded and connected with the moving block 5 through the jacks 403. Plug rods 501 are fixedly installed at the front and rear ends of the moving block 5, and the plug rods 501 are embedded inside the jacks 403. A scraper 502 is fixedly installed at the bottom of the moving block 5, and a scraping strip is arranged at the bottom of the scraper 502. The screw holes 402 arranged on the front and rear sides of the upper end of the fixed end 401 facilitate the threaded connection between the connecting block 4 and the baffle 1, ensuring the firmness and stability of the connection. The plurality of jacks 403 equidistantly arranged on the inner side surface of the connecting block 4 provide multiple options for the position adjustment of the moving block 5, enabling the operator to fix the moving block 5 at different positions according to actual needs, so as to adapt to kraft papers of different thicknesses. During use, one connecting block 4 is fixed through the fixed end 401, and then the corresponding jack 403 is selected according to the thickness of the kraft paper. The moving block 5 is embedded inside the jack 403 through the plug rod 501. Then, another connecting block 4 is nested on the plug rod 501 at the other end of the moving block 5 and fixed on the baffle 1 through the fixed end 401 to realize the installation of the connecting block 4 and the moving block 5. When it is necessary to change the height of the moving block 5, only one connecting block 4 needs to be disassembled, and then the moving block 5 is adjusted according to the need, embedded into another jack 403, and then the disassembled connecting block 4 is reinstalled. When the water-soaked kraft paper is conveyed to the bottom of the moving block 5 by the conveyor belt 102, the scraper 502 uses the scraping strip to scrape off the excess water on the surface of the kraft paper, ensuring that the amount of water on the kraft paper is appropriate, avoiding excessive softening of the kraft paper due to too much water and affecting the firmness of packaging. At the same time, the scraping strip can also make the water more evenly distributed on the kraft paper, improving the wetting effect.

[0027] Working principle: When the kraft paper needs to be packed and moistened, place the kraft paper on the conveyor belt 102. The conveyor belt 102 starts to run and drives the kraft paper to move downward under the fixed platform 2. When the kraft paper needs to be moistened, the water in the water tank 201 will enter the inside of the water outlet pipe 3. At this time, if spraying is required, the solenoid valve 301 is opened to allow the water to flow downward through the water outlet pipe 3. The nozzle 303 at the outlet of the water outlet pipe 3 sprays the water onto the kraft paper in a specific form to moisten the kraft paper. During this process, the flowmeter 302 monitors the water flow in real time. The operator can adjust the opening degree of the solenoid valve 301 according to the water volume information displayed by the flowmeter 302 and the requirements of kraft paper with different materials and thicknesses. When the water volume is too large, appropriately reduce the opening degree of the solenoid valve 301 to reduce the water flow through volume and prevent the kraft paper from being overly moistened and affecting the packing quality; when the water volume is too small, increase the opening degree of the solenoid valve 301 to increase the water spray volume to flexibly adapt to various kraft papers with different materials and thicknesses. The moistened kraft paper continues to move to the right along the conveyor belt 102. When it reaches under the moving block 5, the height of the moving block 5 can be adjusted according to the thickness of the kraft paper. A number of jacks 403 equidistantly arranged on the inner side of the connecting block 4 provide multiple choices for the position adjustment of the moving block 5. The operator can embed the moving block 5 into the jacks 403 at different positions through the insertion rod 501 according to the actual needs to adapt to kraft papers with different thicknesses. The scraper 502 at the bottom of the moving block 5 uses the scraping strip to scrape off the excess water on the kraft paper, which can ensure that the water volume on the kraft paper is appropriate, avoid the kraft paper becoming overly soft due to excessive water volume and affecting the packing firmness. At the same time, the scraping strip can also make the moisture more evenly distributed on the kraft paper and improve the moistening effect.
