Description

Technical Field

[0001] This utility model belongs to the field of carpet production adhesive application technology, specifically relating to an adhesive application device for carpet production. Background Technology

[0002] Carpets, as a popular and versatile floor covering material, are commonly found in private residences seeking warmth and comfort, hotels and restaurants emphasizing quality service, conference rooms requiring a professional and quiet environment, leisure and entertainment venues, stadiums and exhibition halls with high traffic and a need for sound absorption, and even the interiors of vehicles, ships, and airplanes with specific environmental requirements. Carpets are primarily composed of natural fibers such as cotton, linen, wool, and silk, or chemically synthesized fibers such as nylon, polyester, and polypropylene. These materials are meticulously crafted using traditional handcrafting techniques or modern mechanical processing. Laying carpets not only effectively absorbs footsteps and vibrations from moving objects, significantly reducing unavoidable noise interference on hard surfaces and creating a more tranquil atmosphere, but their soft texture also greatly enhances foot comfort when walking or standing, increases the coefficient of friction, and effectively prevents accidental slips. Furthermore, with their rich colors, varied patterns, and unique textures, carpets have become an important decorative element for beautifying interior spaces and enhancing the overall style and taste of the environment. It is worth noting that there is a key process in the production of carpets: using a specialized adhesive applicator, a layer of adhesive is evenly applied to the bottom of the carpet to bond a waterproof layer with specific functions. This process is crucial for improving the durability and applicability of the carpet.

[0003] Currently, existing adhesive application equipment cannot guarantee the thickness of the adhesive layer when spraying it onto carpets. Furthermore, due to the physical spacing of multiple nozzles on the device, if parameters such as nozzle distance, spray angle, and pressure are not precisely optimized, it is highly susceptible to excessive adhesive buildup in overlapping areas, while insufficient or missed areas are covered. This uneven distribution of adhesive at critical bonding interfaces directly results in the inability to form a continuous, dense, and sufficiently strong adhesive film between the waterproofing layer and the carpet substrate in areas with insufficient or missing adhesive when the waterproofing material is pressed onto the back of the carpet. Microscopic or macroscopic adhesive gaps and weak points inevitably occur. These gaps and weak points greatly weaken the bonding strength between the waterproof layer and the carpet body. During subsequent handling, laying, and use, the carpet will inevitably be subjected to external forces such as stretching, bending, and trampling. The stress concentrated in the weak adhesive areas will cause the gaps to widen further, eventually leading to the waterproof layer peeling off locally or even falling off over a large area from the carpet base. This not only directly destroys the carpet's proper waterproof and moisture-proof functions, but also, because it is an inherent defect formed during the production process, it is exposed in the quality inspection stage or at the beginning of user use, seriously reducing the overall pass rate and market yield of carpet products.

[0004] Therefore, to address the problem of uneven glue distribution caused by the spacing between nozzles in the existing glue application equipment, resulting in gaps between the waterproof layer and the carpet and making it easy for the glue to fall off, a glue application equipment for carpet production can be designed. Utility Model Content

[0005] To overcome the problem that existing adhesive application devices, due to the spacing between nozzles, result in uneven adhesive distribution, leaving gaps between the waterproof layer and the carpet, making it prone to peeling off.

[0006] The technical solution of this utility model is as follows: a glue application device for carpet production, including a conveyor belt; it also includes a scraper and a limiting plate. A glue storage tank is provided on the conveyor belt. Multiple nozzles are installed at equal intervals from left to right at the bottom of the glue storage tank. Each nozzle has a built-in pump. A scraper located behind the nozzle is fixedly connected to the bottom of the glue storage tank. A column is fixedly connected to the bottom of the glue storage tank. Two L-shaped limiting plates are provided between the columns. A bidirectional threaded rod is rotatably connected between the columns. A screw hole matching the bidirectional threaded rod is opened on the limiting plate.

[0007] Preferably, the limiting plate moves to both sides of the carpet to restrict the flow range of the adhesive. The nozzle sprays the adhesive stored in the adhesive tank onto the carpet. The carpet is moved by the conveyor belt, comes into contact with the fixed baffle, and is flattened by the baffle, so that the adhesive is evenly distributed on the carpet.

[0008] Preferably, a limiting post is fixedly connected between the columns, located on the lower side of the bidirectional threaded rod, and a limiting plate is sleeved on the outside of the limiting post.

[0009] Preferably, a No. 1 motor is installed on the outside of the column, and the output end of the No. 1 motor is fixedly connected to the bidirectional threaded rod. The No. 1 motor is used to drive the bidirectional threaded rod to rotate.

[0010] Preferably, a mounting base is fixedly connected to the bottom of the column, with the bottom of the mounting base closely attached to the top of the conveyor belt frame, and an anchoring hole is provided on the mounting base through the body of the mounting base.

[0011] Preferably, the glue storage tank has a door installed at the top, a heating chamber inside the storage tank containing glue, and a slot at the bottom of the heating chamber communicating with the nozzle.

[0012] Preferably, a stirring shaft is rotatably connected inside the heating chamber, and multiple stirring blocks arranged equidistantly from left to right are fixedly connected to the outside of the stirring shaft.

[0013] Preferably, a second motor is installed on the outside of the glue storage tank. The output end of the second motor is fixedly connected to the stirring shaft, and the second motor is used to drive the stirring shaft to rotate.

[0014] The beneficial effects of this utility model are:

[0015] By installing a scraper on one side of the glue storage tank in the opposite direction of the nozzle and the conveyor belt, and by using a limiting plate to closely adhere to the edge of the carpet, the flow range of the glue is restricted. The scraper flattens the glue sprayed on the carpet by the nozzle, making it evenly distributed, reducing the gap between the waterproof layer and the carpet during spraying, improving the tightness of the connection between the waterproof layer and the carpet, and increasing the yield rate of the carpet.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a glue-applying device for carpet production, including a conveyor belt 1; it also includes a scraper 2 and a limiting plate 3. A glue storage tank 4 is mounted on the conveyor belt 1. Multiple nozzles 5 are equidistantly arranged from left to right at the bottom of the glue storage tank 4. Each nozzle 5 has a built-in pump. The scraper 2, located behind the nozzles 5, is fixedly connected to the bottom of the glue storage tank 4. A column 6 is fixedly connected to the bottom of the glue storage tank 4. Two L-shaped limiting plates 3, facing each other, are positioned between the columns 6. A bidirectional threaded rod 7 is rotatably connected between the columns 6. The limiting plates 3 have threaded holes matching the bidirectional threaded rod 7. The limiting plates 3 move to the sides of the carpet to restrict the flow of glue. The nozzles 5 spray the glue stored in the glue storage tank 4 onto the carpet. The carpet is moved by the conveyor belt 1. The adhesive plate 3 moves and contacts the fixed baffle, and is flattened by the baffle, so that the adhesive is evenly distributed on the carpet. The columns 6 are fixedly connected with the limiting post 8 set on the lower side of the bidirectional threaded rod 7. The limiting plate 3 is sleeved on the outside of the limiting post 8. The limiting post 8 can guide the movement of the limiting plate 3 and prevent the limiting plate 3 from rotating with the bidirectional threaded rod 7. The two ends of the bidirectional threaded rod 7 are provided with threads with opposite rotation directions. This design allows the two limiting plates 3, which are screwed on different thread structures, to move in opposite directions due to the rotation of the bidirectional threaded rod 7. A first motor 9 is installed on the outside of the column 6. The output end of the first motor 9 is fixedly connected to the bidirectional threaded rod 7. The first motor 9 is used to drive the bidirectional threaded rod 7 to rotate and can provide power for the movement of the limiting plate 3.

[0024] Please see Figures 4-5In this embodiment, a mounting base 10 is fixedly connected to the bottom end of the column 6. The bottom end of the mounting base 10 is close to the top end of the side frame of the conveyor belt 1. An anchoring hole 11 is provided on the mounting base 10, penetrating the body of the mounting base 10. By passing the anchor through the anchoring hole 11, the mounting base 10 and the glue storage tank can be fixed together above the conveyor belt 1. A door 12 is installed on the top of the glue storage tank 4. A heating chamber 13 is provided inside the glue storage tank 4. The heating chamber 13 contains glue. A slot communicating with the nozzle 5 is provided at the bottom end of the heating chamber 13. The heating chamber 13 can heat the internal... The glue is heated to prevent it from solidifying. A stirring shaft 14 is rotatably connected inside the heating chamber 13. Multiple stirring blocks 15 are fixedly connected to the outside of the stirring shaft 14, arranged equidistantly from left to right. The stirring shaft 14 drives the stirring blocks 15 to rotate, thereby driving the glue to rotate, thus avoiding uneven heating. A second motor 16 is installed on the outside of the glue storage tank 4. The output end of the second motor 16 is fixedly connected to the stirring shaft 14. The second motor 16 is used to drive the stirring shaft 14 to rotate and can provide power for the rotation of the stirring shaft 14.

[0025] During installation, the worker first places the mounting base 10 on the top of the conveyor belt 1, then passes the anchor through the anchor hole 11 on the mounting base 10, thereby fixing the column 6 and the glue storage box 4 fixed on the column 6 above the conveyor belt 1. The glue is poured into the heating chamber 13, then the cover is closed, the heating function of the heating chamber 13 is started, and the second motor 16 is started. The second motor 16 drives the stirring shaft 14 to rotate the glue.

[0026] During the adhesive spraying process, the carpet is placed on the conveyor belt 1, and the first motor 9 is started. The first motor 9 drives the bidirectional threaded rod 7 to rotate. Under the restriction of the limit post 8, the two limit plates 3 with different threaded rod structures screwed on the bidirectional threaded rod 7 move towards the middle until they are close to the two edges of the carpet. The conveyor belt 1 is started, and the nozzle 5 starts the internal pump to extract the adhesive and spray it on the carpet surface. As the carpet moves with the conveyor belt 1, the scraper 2 will scrape the adhesive on top and spread it evenly on the carpet surface.

[0027] Through the above steps, the existing scraper 2, which is installed on one side of the glue storage tank 4 in the opposite direction of the nozzle 5 and the conveyor belt 1, and the limiting plate 3 is close to the edge of the carpet, restricts the flow range of the glue. The scraper 2 flattens the glue sprayed on the carpet by the nozzle 5, making it evenly distributed, reducing the gap between the waterproof layer and the carpet when spraying, improving the tightness of the connection between the waterproof layer and the carpet, and improving the yield of carpets. This solves the problem that the existing glue application device has uneven glue distribution due to the interval between the nozzles 5, which leaves gaps between the waterproof layer and the carpet and makes it easy to fall off.
