Description

TECHNICAL FIELD

[0001] The application relates to the technical field of gluing devices, in particular to a continuous gluing device for carpets. BACKGROUND

[0002] The existing carpet gluing device has a significant defect in tension control. Most devices rely on manually controlled screws to adjust the position of the roller in contact with the carpet to achieve tension adjustment. This adjustment method is not only cumbersome to operate, but also has a very slow response speed, and cannot accurately adjust in real time according to the actual tension state of the carpet. In the actual production process, factors such as the material, thickness and unwinding speed of the carpet may cause changes in tension, and manual adjustment often cannot keep up with this rhythm, resulting in the carpet being loose or overly tight during the gluing process. A loose carpet will result in uneven gluing, and even poor glue penetration. Overly tight carpet may damage the fibers, affecting its appearance and service life. CONTENT OF THE UTILITY MODEL

[0003] The application aims to solve the problem that the existing carpet gluing device relies on manually controlled screws to adjust the position of the roller in contact with the carpet, and cannot accurately adjust in real time according to the actual tension state of the carpet in the actual production process.

[0004] To solve the above technical problems, the application provides a continuous gluing device for carpets, which comprises a rack, a unwinding assembly arranged at one end of the upper part of the rack and used to unwind the carpet at a uniform speed, a gluing assembly arranged at the top of the rack and used to glue the carpet by rotary scraping, and a tensioning assembly arranged inside the rack and used to adaptively tension the carpet by gravity.

[0005] The continuous gluing device of the application is designed with a unwinding assembly, a gluing assembly and a tensioning assembly. Therefore, the carpet can be unwound and flattened at a uniform speed by the unwinding assembly and the gluing assembly, and the tensioning assembly can adaptively and timely adjust the tension of the carpet according to its own tension. The application solves the problem that the existing carpet gluing device relies on manually controlled screws to adjust the position of the roller in contact with the carpet, and cannot accurately adjust in real time according to the actual tension state of the carpet in the actual production process.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example

[0016] This application relates to a continuous adhesive application apparatus for carpets, such as... Figures 1-6 As shown, the adhesive application device includes a frame 3, an unwinding assembly 2, an adhesive application assembly 1, and a tensioning assembly 4. The frame 3 serves as an upright foundation support. The unwinding assembly 2 is located at one end of the upper part of the frame 3 and unwinds the carpet at a uniform speed. The adhesive application assembly 1 is located at the top of the frame 3 and applies adhesive to the carpet using a rotating scraping method. The tensioning assembly 4 is located inside the frame 3 and applies adaptive tension to the carpet using gravity. Through the combination of the unwinding assembly 2, the adhesive application assembly 1, and the tensioning assembly 4, it is ensured that the carpet maintains a constant tension during the adhesive application process, avoiding the impact on adhesive quality due to slackness or excessive tightness. At the same time, since the tension adjustment process is fully automated, production efficiency is greatly improved and the labor intensity of operators is reduced.

[0017] The unwinding assembly 2 comprises a frame body 10, a first motor 5, an inflatable shaft 6, a guide rod 7, a sliding block 8, a second motor 11 and a first guide roller 9. The frame body 10 is stably arranged at one end of the upper part of the rack 3 to provide a support structure for other components. The upper part of the frame body 10 is transversely provided with the inflatable shaft 6 through a bearing seat. The inflatable shaft 6 can conveniently and quickly load and unload the carpet roll. One end of the inflatable shaft 6 is connected with the first motor 5. The motor is responsible for driving the inflatable shaft 6 to rotate at a constant speed, so as to realize the stable unwinding of the carpet. In order to ensure the uniformity and stability of unwinding, the first motor 5 can adopt a servo motor with high precision control performance. Considering that there are various models and sizes of carpets with different widths, the unwinding assembly 2 is designed with a flexible adaptation mechanism. The top and bottom of the frame body 10 are symmetrically provided with sliding blocks 8. These sliding blocks 8 are connected with the frame body 10 and can freely slide on the guide rods 7 symmetrically arranged on the upper part of the rack 3. Through this design, the frame body 10 can be adjusted horizontally according to the width of the carpet to adapt to the unwinding requirements of carpets with different widths. In order to further improve the automation degree of the unwinding assembly 2, the upper part of the rack 3 is further provided with the second motor 11 connected with the frame body 10. The second motor 11 is a lead screw motor composed of a servo motor. The motor can drive the sliding block 8 to slide on the guide rod 7, so as to realize the automatic positioning and adjustment of the frame body 10. In addition, the frame body 10 is further provided with the first guide roller 9 on one side. The guide roller plays a supporting role in the carpet unwinding process, ensuring that the carpet can be smoothly unwound from the inflatable shaft 6 and smoothly enter the subsequent gluing and tensioning processes. The carpet roll is loaded on the unwinding assembly 2 through the inflatable shaft 6 and is driven by the first motor 5 to unwind at a constant speed. The unwound carpet is supported by the first guide roller 9, enters the tensioning assembly 4 for adaptive tensioning adjustment, then enters the gluing assembly 1 for gluing operation, and finally outputs the carpet product after tensioning and gluing treatment.

[0018] The tensioning assembly 4 comprises vertical plates 12, chain rollers 13, chain wheels 14, chains 15, springs 17, floating rollers 16 and second guide rollers 18, the vertical plates 12 are symmetrically arranged inside the frame 3 to provide stable support for other components, the upper part of the vertical plates 12 is vertically and symmetrically provided with chain wheels 14, the chain wheels 14 are connected with the vertical plates 12 through precise bearings to ensure smooth rotation of the chain wheels 14, the outside of the chain wheels 14 is wound with chains 15, the upper part of the chains 15 is connected with floating rollers 16, the design of the floating rollers 16 enables them to freely rise and fall with the change of the carpet tension, thereby realizing self-adaptive tensioning of the carpet, in order to ensure that the chains 15 always maintain constant tension during long-term use, the upper part of the chains 15 is also connected with springs 17 in a stretched state, the springs 17 can balance the relaxation of the chains 15 due to the increase of use time, so as to keep the travel path of the chains 15 around the chain wheels 14 constant, thereby improving the stability and reliability of the tensioning assembly 4, the second guide rollers 18 are arranged between the upper chain wheels 14, the carpet is arranged around the floating rollers 16 through the reversing of the second guide rollers 18, this arrangement enables the carpet to be vertically tensioned by the gravity of the floating rollers 16 when passing through the tensioning assembly 4, at the same time, the floating rollers 16 can also be vertically lifted and lowered along the chain wheels 14 by the chains 15 based on the tension of the carpet itself, thereby realizing real-time adjustment of the carpet tension, when the carpet tension increases, the floating rollers 16 will rise correspondingly, and move around the chain wheels 14 through the chains 15, when the carpet tension decreases, the floating rollers 16 will descend, in this way, the tensioning assembly 4 can ensure that the carpet always maintains the best tensioning state during the entire gluing process.

[0019] The gluing assembly 1 comprises a frame plate 19, a clamp roller 24, a supporting roller 23, a scraping roller 22, a third motor 21 and a fourth motor 20. The frame plate 19 is symmetrically arranged on the upper portion of the frame 3 and is used to support and fix other components. The supporting roller 23 is horizontally arranged between the frame plates 19 and can rotate around the frame plates 19. The supporting roller 23 is used to support and convey the carpet. The clamp roller 24 is arranged on one side of the supporting roller 23 and can adjust the distance with the supporting roller 23. The clamp roller 24 cooperates with the supporting roller 23 and is used to clamp and flatten the carpet. The scraping roller 22 is arranged above the supporting roller 23 and can adjust the distance with the supporting roller 23. The scraping roller 22 is used to scrape the excess glue on the surface of the carpet. The clamp roller 24 and the scraping roller 22 can be adjusted in horizontal position by the slide rails and slide seats arranged on the upper portion of the frame plate 19. In this way, the distance between the clamp roller 24, the scraping roller 22 and the supporting roller 23 can be conveniently adjusted to adapt to carpets of different thicknesses and types. The outer side of the supporting roller 23 is provided with the third motor 21 which drives the rotation of the supporting roller 23. The outer side of the clamp roller 24 is provided with the fourth motor 20 which drives the rotation of the clamp roller 24. Through the driving of the motors, the carpet can be effectively rolled and flattened between the clamp roller 24 and the supporting roller 23. The scraping roller 22 has a triangular notch on the upper portion and can scrape the excess glue on the surface of the carpet by means of the notch to ensure uniform glue application. The frame plate 19 is also provided with a supporting plate 25 in an inclined state. The supporting plate 25 is uniformly and spacedly provided with glue plates 26. The glue plates 26 are filled with liquid glue. When the carpet passes between the supporting roller 23 and the scraping roller 22, the glue can be attached to the surface of the carpet to realize uniform gluing.

[0020] In use, the carpet to be glued is input from one side of the device, ensuring that the carpet is flat and wrinkle-free. The distance between the clamp roller 24 and the supporting roller 23 is adjusted to adapt to the thickness of the carpet and ensure that the carpet remains stable during the conveying process. When the carpet passes through the supporting roller 23, the third motor 21 drives the rotation of the supporting roller 23 to move the carpet forward. The clamp roller 24 cooperates with the supporting roller 23 to clamp and flatten the carpet under the driving of the fourth motor 20, ensuring that the surface of the carpet is flat and wrinkle-free. When the carpet passes through the gluing area, the liquid glue flows out from between the glue plates 26 and is uniformly applied to the surface of the carpet. The scraping roller 22 is fixed above the carpet and its triangular notch scrapes the excess glue on the surface of the carpet to ensure that the glue layer is uniform and not too thick. During the gluing process, the operator needs to monitor the gluing quality in real time, including the uniformity and thickness of the glue layer. If the gluing is found to be uneven or the glue layer is found to be too thick, the slide rails and slide seats can be adjusted in time to change the positions of the clamp roller 24 and the scraping roller 22 to optimize the gluing effect. The remaining amount of liquid glue is checked regularly to ensure continuous gluing during the process. After gluing is completed, the carpet leaves the gluing device for subsequent drying and winding operations.
