Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, and in particular to an overpressure device for a horizontal laminating machine paper unwinding rack. Background Technology

[0002] A horizontal laminating machine is used to bond two or more layers of materials together with an adhesive, giving the original materials new functions. For example, it is often used to bond films with aluminum foil, films with paper, and non-woven fabrics. It can also be used to laminate films, sponges, and fabrics. A horizontal laminating machine requires an overpressure device to facilitate subsequent operations.

[0003] Existing horizontal laminating machines use a single pressure roller to squeeze the paper and bond it together. However, in actual use, relying solely on a single pressure roller to squeeze the paper can easily lead to poor bonding, resulting in unevenness in the finished paper products and consequently affecting the quality of the paper production. Utility Model Content

[0004] The purpose of this utility model is to provide an overpressure device for the paper unwinding rack of a horizontal laminating machine, so as to solve the problem mentioned in the background art that the existing overpressure devices for the paper unwinding rack of a horizontal laminating machine have poor paper compression force during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an overpressure device for a horizontal composite machine paper unwinding rack, comprising a support frame and a base, wherein two support frames are welded to both sides of the top of the base;

[0006] A feeding shaft is provided between the two support frames, and paper rolls are sleeved on the outer side of the feeding shaft. An overpressure mechanism is provided inside the base. Two extrusion plates are slidably arranged on the base, and a side plate is provided on one side of each extrusion plate. A collection frame is fixed at the bottom of a set of side plates, and a glue scraping mechanism is provided inside each collection frame. An overpressure roller is provided on one side of each side plate.

[0007] When using the overpressure device of the paper unwinding rack of a horizontal laminating machine according to this technical solution, multiple overpressure rollers, in cooperation with the overpressure mechanism and the extrusion plate, exert high-intensity extrusion on the paper, thereby improving the smoothness of the paper and thus improving its production quality. The overpressure mechanism includes a double-headed motor, which is located inside the support frame. Adjusting shafts are fixed on both sides of the double-headed motor, and adjusting blocks are sleeved on the outer side of the adjusting shafts. Guide blocks are provided at the bottom of the adjusting blocks, and guide grooves are provided on the outer side of the guide blocks. The guide grooves are opened inside the support frame, and the guide blocks slide inside the guide grooves. The adjusting blocks are slidably connected to the support frame through the guide blocks and guide grooves.

[0008] Preferably, there are two adjusting shafts, which are symmetrically distributed, and both adjusting shafts have external threads on their outer sides.

[0009] Preferably, the scraping mechanism includes a fixed plate, which is disposed inside the collection frame. A compression spring is fixed inside the fixed plate, and a baffle is fixed to the top of the compression spring. Slider blocks are fixed on both sides of the baffle, and a sliding groove is provided on the outer side of each slider. The sliding groove is opened inside the fixed plate. A connecting plate is fixed to the top of the baffle, and a scraper is provided at the top of the connecting plate.

[0010] Preferably, the fixing plate is provided in three sets, each set of the fixing plate has two fixing plates, and all three sets of the fixing plates have an internal hollow structure.

[0011] Preferably, the compression spring is provided in three sets, and all three sets of compression springs are in a stretched state inside the fixed plate.

[0012] Preferably, the scraper is provided in three sets, one side of each of the three sets of scrapers is slidably attached to one side of the pressure roller, and all three scrapers are made of rubber.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the overpressure device of the paper unwinding rack of the horizontal laminating machine not only improves the squeezing force on the paper, but also has the function of scraping glue.

[0014] By starting the dual-head motor to drive the adjusting shaft to rotate, and under the action of the guide block and guide groove, the two adjusting blocks are driven to move horizontally relative to each other, so that the extrusion plate moves synchronously, and then drives the super pressure roller to move synchronously. By setting multiple super pressure rollers, the paper is subjected to high-intensity extrusion, thereby improving the extrusion effect and thus improving the smoothness of the paper during processing.

[0015] The baffle is pushed horizontally by the compression spring, and the connecting plate is driven to move upward synchronously under the action of the slide and the slider, until one side of the scraper and one side of the pressure roller are in contact with each other. The above operation facilitates the automatic scraping of the glue stuck on the pressure roller, thereby reducing the labor intensity of the workers and improving their work efficiency.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figures 1-5 An embodiment of this utility model is provided: a horizontal composite machine paper unwinding rack overpressure device, including a support frame 1 and a base 9. Two support frames 1 are welded to both sides of the top of the base 9. A feeding shaft 5 is provided between the two support frames 1, and a paper roll 6 is sleeved on the outside of the feeding shaft 5. An overpressure mechanism 2 is provided inside the base 9.

[0025] The overpressure mechanism 2 includes a dual-head motor 203, which is located inside the support frame 1. Adjustment shafts 201 are fixed on both sides of the dual-head motor 203, and adjustment blocks 205 are sleeved on the outer side of the adjustment shafts 201. Guide blocks 204 are provided at the bottom of the adjustment blocks 205, and guide grooves 202 are provided on the outer side of the guide blocks 204. The guide grooves 202 are opened inside the support frame 1.

[0026] There are two adjusting shafts 201, which are symmetrically distributed, and both adjusting shafts 201 have external threads on their outer sides;

[0027] The guide block 204 slides inside the guide groove 202, and the adjusting block 205 is slidably connected to the support frame 1 through the guide block 204 and the guide groove 202;

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, during use, by starting the dual-head motor 203, the adjusting block 205 is driven to move horizontally under the action of the adjusting shaft 201, thereby driving the extrusion plate 3 to move synchronously, and then causing the super pressure roller 7 to move synchronously. Through the above operation, the paper is subjected to high-intensity extrusion, thereby improving its smoothness.

[0029] The base 9 has two extrusion plates 3 that are slidably arranged, and each of the extrusion plates 3 has a side plate 8 on one side. A collection frame 10 is fixed to the bottom of each set of side plates 8, and a scraping mechanism 4 is provided inside the collection frame 10.

[0030] The adhesive scraping mechanism 4 includes a fixed plate 401, which is disposed inside the collection frame 10. A compression spring 403 is fixed inside the fixed plate 401, and a baffle 405 is fixed to the top of the compression spring 403. Slider 402 is fixed on both sides of the baffle 405, and a sliding groove 404 is provided on the outer side of each slider 402. The sliding groove 404 is opened inside the fixed plate 401. A connecting plate 406 is fixed to the top of the baffle 405, and a scraper 407 is provided to the top of the connecting plate 406.

[0031] There are three sets of fixing plates 401, with two fixing plates 401 in each set, and all three sets of fixing plates 401 have an internal hollow structure.

[0032] Three sets of compression springs 403 are provided, and all three sets of compression springs 403 are in a stretched state inside the fixed plate 401.

[0033] There are three sets of scrapers 407. One side of each of the three sets of scrapers 407 slides and fits against one side of the super pressure roller 7. All three scrapers 407 are made of rubber.

[0034] Each side of the side plate 8 is equipped with an overpressure roller 7;

[0035] Specifically, such as Figure 1 , Figure 2 , Figure 5As shown, during use, the baffle 405 is pushed to move horizontally by the compression spring 403, and the scraper 407 and the super pressure roller 7 are brought into contact with each other under the action of the connecting plate 406. The above operation facilitates the scraping of the glue on the super pressure roller 7, thereby improving the efficiency of paper bonding.

[0036] Working principle: In use, firstly, one side of two paper rolls 6 is passed between two super-pressure rollers 7 and adhesive is applied. The dual-head motor 203 is started to drive the adjusting shaft 201 to rotate. While the adjusting shaft 201 is rotating, it drives the two adjusting blocks 205 to move horizontally relative to each other. This causes the guide block 204 to slide inside the guide groove 202. The guide block 204 can limit the movement of the adjusting block 205 to prevent it from shifting position during movement and affecting subsequent operations. It can also guide the moving adjusting block 205 to improve its stability during movement. While the adjusting block 205 is moving horizontally, it drives the extrusion plate 3 to move horizontally in sync. This makes one side of the paper on one side of the super-pressure roller 7 stick together. By setting multiple super-pressure rollers 7 and distributing them in a staggered manner, the paper can be squeezed multiple times, thereby improving its smoothness.

[0037] Then, when the paper is squeezed, the adhesive easily overflows from one side of the pressure roller 7, causing the compression spring 403 to push the baffle 405 to move upward. This causes the slider 402 to slide inside the groove 404, thus limiting and guiding the moving baffle 405. As the baffle 405 moves upward, it drives the connecting plate 406 to move upward synchronously, which in turn drives the scraper 407 to move upward synchronously until one side of the scraper 407 is in contact with one side of the pressure roller 7. This scrapes off the adhesive adhering to the pressure roller 7, and the scraped adhesive falls into the collection frame 10 for collection, facilitating subsequent use. The above operation improves the efficiency of paper processing.
