Description

Technical Field

[0001] The present invention relates to the technical field of carpet production, specifically a glue coating device for carpet production. Background Art

[0002] A carpet is a textile covering on the ground, used to provide comfort, warmth and decorative effects. It is usually made of fiber materials such as wool, nylon, polyester, etc., and can be used in various places such as homes, offices, hotels, etc., with functions such as sound insulation, anti-slip, and beauty. Currently, carpets generally need to go through several steps such as dyeing, weaving, compounding the base cloth, drying, shearing and trimming the edges, and finishing products. Among them, compounding the base cloth and drying are important steps for the shaping of the base cloth and the bottom cloth, which are crucial for improving the overall quality and use experience of the carpet. It can not only provide stable support for the carpet, maintain the shape and size of the carpet, but also increase the elasticity and softness of the carpet, improve the foot feeling, and at the same time have a certain anti-slip performance, which can increase the friction between the sole and the ground and reduce the risk of slipping.

[0003] In the current carpet production process, the compounding bottom link is essential. To ensure the firm connection between the carpet and the bottom cloth, it is necessary to apply glue to the back of the carpet. However, the existing glue coating devices have defects during operation. Since the bottom surface of the carpet is covered with a large number of dense pile heads, during the roll coating process, cavities and bubbles are extremely likely to form around the pile heads. The existence of these cavities and bubbles interferes with the uniform distribution of the glue liquid, seriously affecting the bonding effect between the bottom cloth and the carpet, and reducing the product quality and stability.

[0004] Therefore, a glue coating device for carpet production is proposed. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. By setting an auxiliary structure, when the conveying roller operates, the pulley is driven to rotate through the toothed belt wheel and the toothed belt. The roller on the pulley rolls in the chute of the push rod, thereby driving the push rod to reciprocate up and down along the limiting conduit. This action causes the pressing rod to move up and down synchronously, intermittently pushing the vibrating piece. After being pushed, the vibrating piece compresses the vibrating spring and moves downward. The plate below it is closely attached to the surface of the carpet and contacts the output end of the vibrating motor at the same time. At this time, the vibration generated by the vibrating motor is efficiently conducted to the surface of the carpet through the vibrating piece and precisely acts on the undried carpet. This design can effectively remove the cavities and bubbles existing in the glue between the tufted carpet and the bottom cloth, and at the same time promote the uniform distribution of the glue. This not only improves the bonding effect between the carpet and the bottom cloth, but also fundamentally improves the quality and stability of the product, greatly reducing the bad phenomena such as carpet delamination and degumming caused by glue problems, and prolonging the service life of the carpet;

[0020] 2. By setting up an auxiliary structure in the present invention, when the lifting hopper plate slides up and down in the glue bin, it drives the valve rod to move synchronously. When the valve rod moves downward, it inserts into the main glue pipe, connecting the glue storage space in the glue bin with the main glue pipe. The insertion of the valve rod pushes the inclined surface push pipe to move to both sides, thereby driving the piston rod to move, sucking the glue liquid in the glue bin, making the glue liquid enter the main glue pipe and the inclined surface push pipe in sequence, and finally flowing into the paste surface glue channel, ensuring that there is always sufficient glue liquid at the blade during the operation of the cutting knife. Then, the piston rod moves to push the glue pushing cone, and the glue pushing cone squeezes the glue liquid in the space isolated by the spring limiting plate at the front and rear ends of the main glue pipe, further supplementing the glue liquid in the paste surface glue channel, and pushing the cutting rod to compress the retracting knife spring and move downward, so that the cutting knife moves downward. With the sufficient glue liquid in the paste surface glue channel, the cutting knife precisely cuts and applies glue to the front and rear fringes of the carpet, not only effectively avoiding the situation of the side edges cracking after cutting, but also reducing the trouble of trimming and edge sealing operations. At the same time, when the lifting hopper plate moves upward, the valve rod is withdrawn, and the piston rod and the inclined surface push pipe in the main glue pipe return to the initial position under the reset action of the spring limiting plate. During the reset process, the glue liquid is squeezed, and the increased pressure opens the one-way valve inside the piston rod, and the glue liquid enters the inner hole of the piston rod and then flows into the isolated space at the front and rear ends of the main glue pipe, realizing the supplement of the glue liquid, providing sufficient glue liquid for the next cutting and gluing operation of the cutting knife, ensuring the coherence and stability of the entire trimming and gluing process. This process not only improves the overall aesthetics of the carpet but also enhances the firmness of the carpet edge, making the product more durable. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The auxiliary structure 2 is arranged on the upper side inside the carpet production structure 1 and is used for vibrating and exhausting the bottom and the carpet after lamination, trimming the edges, and applying glue to fix the edges.

[0048] Among them, the carpet production structure 1 includes a machine body 11. A material feeding channel 111 is provided at the upper middle position inside the machine body 11. Guide rollers 112 are rotatably arranged at the input and output ports of the material feeding channel 111 of the machine body 11 in cooperation with bearing seats. A glue rolling assembly 12 is arranged at the position of the left input port inside the machine body 11. The glue rolling assembly 12 mainly includes a motor, a glue rolling roller group designed according to the carpet size, a sustainable glue supply bin, and an adjustable glue blocking plate, which can stably roll the glue on the bottom surface of the carpet. A bottom cloth supply assembly 13 for providing the bottom cloth is configured on the left side of the upper surface of the machine body 11. A channel communicating downward with the material feeding channel 111 is opened on the right side of the glue rolling assembly 12 inside the machine body 11, and a guide roller 112 is rotatably arranged at the upper port of the channel in cooperation with a bearing seat. Inside the machine body 11, conveying rollers 1111 are rotatably arranged on the upper and lower inner walls of the material feeding channel 111 from the lower port of the bottom cloth input channel to the output port on the right side of the material feeding channel 111 according to the thickness of the carpet and the bottom cloth. The rear ends of the conveying rollers 1111 are connected together by a toothed belt and a toothed pulley, and the front end of one of the conveying rollers 1111 is connected to a driving motor through a coupling, and the driving motor is connected to the surface of the machine body 11 by bolts. An air-heat shaping assembly 113 is installed at the position of the middle left on the upper surface of the inner wall of the material feeding channel 111 inside the machine body 11. The air-heat shaping assembly 113 is composed of a blower and an electric heating plate. Among them, the blower is connected to a pre-opened installation hole in the machine body 11 by bolts, and the installation hole communicates with the material feeding channel 111. The electric heating plate is fixed in a groove opening towards the material feeding channel 111, and a blowing port is provided on the surface of the electric heating plate corresponding to the blower. A heat drying assembly 114 is installed at the position near the output port on the right side of the upper surface of the inner wall of the material feeding channel 111 inside the machine body 11. Both the heat drying assembly 114 and the air-heat shaping assembly 113 are electrically connected to the control terminal of the machine body 11 through wires. An upward-opening glue bin 115 is opened at the middle position between the air-heat shaping assembly 113 and the heat drying assembly 114 inside the machine body 11. A cover plate 1151 is connected to the upper port position of the glue bin 115 by bolts. Bearing frames 1152 and limit guide pipes 1153 are symmetrically fixed on the upper surface of the cover plate 1151. Among them, the limit guide pipes 1153 are located at the middle position on the left and right sides of the cover plate 1151, and the bearing frames 1152 are located at the rear side of the limit guide pipes 1153. Glue collecting grooves 1112 for collecting excess glue are opened downward at both ends of the conveying rollers 1111 corresponding to the front and rear sides of the material feeding channel 111 inside the machine body 11. The lower side of the glue collecting grooves 1112 communicates with a glue hopper 1113 spaced inside the machine body 11 directly below the material feeding channel 111. A glue pump 1114 for pumping glue is installed at the bottom of the glue hopper 1113, and the output end of the glue pump 1114 is connected to the glue bin 115 through a pipeline;

[0049] The auxiliary structure 2 includes a lifting hopper plate 21. The lifting hopper plate 21 is slidably and sealingly arranged inside the glue bin 115. And at the positions near the four corners on the lower surface of the lifting hopper plate 21, a spring rod is respectively fixedly arranged, and the lifting hopper plate 21 is limited inside the glue bin 115 in cooperation with the spring rod. On the left and right sides of the lowest position of the upper surface of the lifting hopper plate 21, a T-shaped push rod 211 is respectively fixedly arranged. And the vertical rod of the push rod 211 is liftably and slidably limited inside the limit conduit 1153. Designated-length limit chutes are respectively opened inside the cross bars of the push rod 211, and are in rolling connection with the rollers fixed on the surface of the wheel disc 212 in cooperation with the chutes. Among them, the rollers are limited to slide left and right reciprocally inside the chutes. The rollers are composed of a wheel and a wheel shaft, and the wheel shaft is fixed on the centrifugal side of the surface of the wheel disc 212. The rear end of the wheel disc 212 has a shaft body, and the rear end of the shaft body passes through the bearing bracket 1152, and is in transmission connection with the conveying roller 1111 through a toothed belt wheel and a toothed belt under the rotational support of the bearing bracket 1152. The left side of the cross bar of the push rod 211 on the left side is fixed to an L-shaped pressure rod 2111. The lower end of the pressure rod 2111 is inserted into the jack opened on the left side of the hot air shaping assembly 113 on the upper surface of the machine body 11, and the lower end of the jack is communicated with the space where the vibrating piece 2112 is located. The vibrating piece 2112 is movably arranged in a columnar groove opened inside the machine body 11 and communicated with the material feeding channel 111 in cooperation with the vibrating spring 2114. And the lower surface of the vibrating piece 2112 is exposed on the upper side of the material feeding channel 111. Inside the machine body 11, several vibration motors 2113 are fixedly arranged at the middle position of the space where the vibrating piece 2112 is located. And the vibration motors 2113 are connected to the control terminal of the machine body 11 through circuits and are regulated by the control terminal of the machine body 11.

[0050] During operation, first start the device, adjust the glue rolling assembly 12 to control the glue coating amount of the glue coating roller. Feed the tufted carpet into the feeding channel 111 from the left guide roller 112. The carpet contacts the glue rolling roller, and the glue is evenly coated on the back of the carpet by the roller coating method. After coating, the carpet moves to the right under the transmission of the glue rolling assembly 12 and enters the range of the transmission roller 1111. When the carpet reaches the left side of the transmission roller 1111, the backing supply assembly 13, in cooperation with the guide roller 112 and the transmission roller 1111, feeds the backing into the feeding channel 111 along the backing input channel and fits it to the glue-coated surface of the carpet. The combined carpet continues to move to the right under the conveyance of the transmission roller 1111. The glue between the tufted carpet and the backing is pushed leftward and to both sides by roller pressure, and the edge glue overflows and falls into the glue collecting groove 1112 and flows into the bottom of the glue hopper 1113. Subsequently, the carpet is conveyed under the transmission roller 1111 to the lower part of the hot air shaping assembly 113 and is preliminarily dried and shaped by hot air. After hot drying, the carpet moves to the lower part of the auxiliary structure 2. During this process, the glue liquid in the glue hopper 1113 is pumped into the glue storage 115 by the glue pump 1114 and accumulates on the upper surface of the lifting hopper plate 21. The disc 212 connected to the transmission roller 1111 drives the push rod 211 to reciprocate up and down along the limit guide pipe 1153 under the support of the bearing frame 1152, driving the pressure rod 2111 and the lifting hopper plate 21 to move up and down. The pressure rod 2111 intermittently pushes the vibrating piece 2112. The vibrating piece 2112 compresses the vibration spring 2114 and moves downward. The plate piece contacts the surface of the carpet and the output end of the vibration motor 2113. The vibration motor 2113 transmits the vibration to the carpet, removing the cavities and bubbles in the glue between the tufted carpet and the backing and promoting the uniform distribution of the glue.

[0051] In summary, by setting the auxiliary structure 2, when the transmission roller 1111 is operating, the disc 212 is driven to rotate by the toothed belt wheel and the toothed belt. The roller on the disc 212 rolls in the chute of the push rod 211, thereby driving the push rod 211 to reciprocate up and down along the limit guide pipe 1153. This action causes the pressure rod 2111 to move up and down synchronously, intermittently pushing the vibrating piece 2112. After being pushed, the vibrating piece 2112 compresses the vibration spring 2114 and moves downward. The plate piece below it closely adheres to the surface of the carpet and contacts the output end of the vibration motor 2113. At this time, the vibration generated by the vibration motor 2113 is efficiently transmitted to the surface of the carpet through the vibrating piece 2112 and precisely acts on the undried carpet. This design can effectively remove the cavities and bubbles existing inside the glue between the tufted carpet and the backing, and at the same time promote the uniform distribution of the glue. This not only improves the adhesion effect between the carpet and the backing, but also fundamentally improves the quality and stability of the product, greatly reducing the bad phenomena such as carpet delamination and degumming caused by glue problems and extending the service life of the carpet.

[0052] As an embodiment of the present invention, as Figures 6 to 10As shown, a plurality of T-shaped valve stems 221 are fixedly arranged between the two push rods 211 inside the lifting bucket plate 21, and the lower end of the valve stem 221 is inserted into the connecting branch pipe 22 in a sliding and sealing manner, and a valve hole 222 is opened inside the valve stem 221 along the axis from top to bottom. When the lifting bucket plate 21 moves downward, the lower end of the valve hole 222 is connected to the inside of the main hose 23, and the lower end of the connecting branch pipe 22 is fixedly connected to one main hose 23 respectively, and the connecting branch pipe 22 is vertically arranged at a right angle to the main hose 23. The inside of the main hose 23 is symmetrically slidably provided with an inclined push pipe 232 at the lower end of the connecting branch pipe 22, and the inclined push pipe 232 is symmetrically slidably provided at the front and rear sides of the main hose 23. One end of the push tube 232 is fixed to the piston rod 231, and a through hole for the flow of glue is provided at the inclined end of the inclined push tube 232, and the push of the valve stem 221 is not affected. The piston rod 231 is provided with a sliding seal inside the main rubber hose 23, and a through hole that passes through the front and back is provided at the axis of the piston rod 231, and a one-way valve is installed at the input end of the piston rod 231 connected to the inclined push tube 232. The rod body of the piston rod 231 passes through the spring limiting plate 233 and is fixed to the push rubber cone 234 at the opposite end of the piston. The spring limiting plate 233 is composed of a ring plate and a spring fixed to the ring plate, wherein the other end of the spring is connected to the piston rod The piston of 231 is fixed, and the ring plate is fixedly arranged at the position near both ends inside the main rubber tube 23. Both ends of the main rubber tube 23 are expanded and opened in the axial direction according to the rubber pushing cone 234 to open a cone groove 235, and the lower side of the inner wall of the cone groove 235 is provided with a medium-shaped through hole groove, and the through hole groove cooperates with the retreat spring 237 to limit the sliding with the push cutting rod 236. One end of the retreat spring 237 is fixed to the ring plate integrally arranged on the surface of the push cutting rod 236. The lower end of the push cutting rod 236 passes through the through hole groove and is fixed to the cutter 238, and a paste surface is opened from the axial position of the push cutting rod 236 to the cut surface of the cutter 238 facing the carpet. The glue channel 239 is provided with a strip shape at the lower end of the glue channel 239 for the paste surface along the cutter 238. The connecting branch pipe 22 and the main rubber pipe 23 are fixedly arranged in a pipe groove connected and opened just below the glue bin 115 inside the machine body 11, and the cutter 238 is slidably arranged in a lifting groove opened on the side of the carpet corresponding to the upper part of the material feeding channel 111 inside the machine body 11. The side surfaces of the leftmost and rightmost main rubber pipes 23 are rotatably connected with edge pressing rollers 24 at the front and rear sides of the carpet in cooperation with the support frame, and the pipe ends of the main rubber pipes 23 are rotatably sleeved with edge pressing rollers 24, and the lower wheel surface of the edge pressing roller 24 is flush with the lower roller surface of the upper conveying roller 1111.

[0053] During operation, the lifting hopper plate 21 slides up and down in a sealed manner within the glue bin 115, driving the valve stem 221 to move synchronously. When the valve stem 221 moves downward, it inserts into the main glue pipe 23, connecting the glue storage space of the glue bin 115 with the main glue pipe 23. At the same time, the valve stem 221 pushes the inclined surface push pipe 232 to move to both sides, driving the piston rod 231 to suck glue into the main glue pipe 23 and the inclined surface push pipe 232. The movement of the piston rod 231 pushes the glue pushing cone 234, squeezing the glue into the paste surface glue channel 239 to ensure sufficient glue at the cutter 238. The glue pushing cone 234 pushes the cutting rod 236, causing the cutter 238 to move downward, cooperating with the glue in the paste surface glue channel 239 to cut and apply glue to the carpet fringe, preventing the side from splitting. When the lifting hopper plate 21 moves upward, the valve stem 221 is withdrawn, disconnecting the glue bin 115 from the main glue pipe 23. The piston rod 231 and the inclined surface push pipe 232 are reset under the action of the spring limiting plate 233, squeezing the glue to open the one-way valve inside the piston rod 231, replenishing the glue to the isolation spaces at both ends of the main glue pipe 23, and flowing into the paste surface glue channel 239 to prepare the glue for applying to the cutter 238. After the carpet edge trimming, it is conveyed by the conveyor roller 1111 to the lower part of the hot drying assembly 114 for high-temperature drying and shaping, and then is assisted to be sent out by the guide roller 112 at the output port of the right-side feeding channel 111.

[0054] In summary, by setting the auxiliary structure 2, when the lifting hopper plate 21 slides up and down in the glue storage bin 115, it drives the valve rod 221 to move synchronously. When the valve rod 221 moves downward, it inserts into the main rubber tube 23, connecting the glue storage space of the glue storage bin 115 with the main rubber tube 23. The insertion of the valve rod 221 pushes the inclined surface push tube 232 to move to both sides, thereby driving the piston rod 231 to move, sucking the glue liquid in the glue storage bin 115, making the glue liquid enter the main rubber tube 23 and the inclined surface push tube 232 in sequence, and finally flowing into the paste surface glue channel 239, ensuring that there is always sufficient glue liquid at the cutting edge of the cutter 238 during operation. Then, the piston rod 231 moves to push the glue pushing cone 234, and the glue pushing cone 234 squeezes the glue liquid in the space isolated by the spring limiting plate 233 at the front and rear ends of the main rubber tube 23, further supplementing the glue liquid in the paste surface glue channel 239, and pushing the push cutting rod 236 to compress the retracting spring 237 to move downward, so that the cutter 238 moves downward. With the sufficient glue liquid in the paste surface glue channel 239, the cutter 238 can accurately cut and apply glue to the front and rear fringes of the carpet, not only effectively avoiding the situation of the cut side cracking, but also reducing the trouble of trimming and edge sealing operations. At the same time, when the lifting hopper plate 21 moves upward, the valve rod 221 is withdrawn, and the piston rod 231 and the inclined surface push tube 232 in the main rubber tube 23 return to their initial positions under the reset action of the spring limiting plate 233. During the reset process, the glue liquid is squeezed, and the increased pressure opens the one-way valve inside the piston rod 231, and the glue liquid enters the inner hole of the piston rod 231 and then flows into the isolated spaces at the front and rear ends of the main rubber tube 23 to achieve the replenishment of the glue liquid, providing sufficient glue liquid for the next cutting and glue application operation of the cutter 238, ensuring the coherence and stability of the entire trimming and sealing process. This process not only improves the overall aesthetics of the carpet, but also enhances the firmness of the carpet edge, making the product more durable.

[0055] Working principle: During operation, first start the device and adjust the glue roller assembly 12 to control the amount of glue applied by roller coating. Then, feed the tufted carpet into the feeding channel 111 from the guide roller 112 on the left side. The carpet entering the feeding channel 111 will first come into contact with the glue roller of the glue roller assembly 12, and the glue will be evenly coated on the back of the carpet by roller coating. Then, the glued carpet will move to the right under the conveyance of the glue roller assembly 12 and enter the conveyance range of the conveyance roller 1111. When the carpet reaches the left side of the conveyance roller 1111, the backing supply assembly 13 will cooperate with the guide roller 112 and the conveyance roller 1111 at the lower port of the backing input channel to feed the backing into the feeding channel 111 along the backing input channel, and make the backing intersect and adhere to the glue-coated surface of the carpet. The adhered carpet will continue to move to the right under the conveyance of the conveyance roller 1111. During the movement, the adhesive between the tufted carpet and the backing will be pushed leftward and to both sides due to the extrusion under the roller pressure of the conveyance roller 1111. At this time, the adhesive on the front and rear sides of the carpet will overflow from the edge of the carpet and fall into the glue collection groove 1112, and then flow into and be stored at the bottom of the glue hopper 1113 along the glue collection groove 1112. At this time, the carpet will move under the conveyance of the conveyance roller 1111 to the lower part of the hot air shaping assembly 113, and the hot air shaping assembly 113 will blow hot air onto the surface of the carpet to perform preliminary drying and shaping on the carpet. After the specified hot drying time, the carpet will continue to move under the conveyance of the conveyance roller 1111 to the lower part of the auxiliary structure 2. During this process, the glue liquid stored inside the glue hopper 1113 will be pumped along the pipeline into the inside of the glue bin 115 by the glue pump 1114 and accumulate on the upper surface of the lifting hopper plate 21. The disk 212, which is connected to the conveyance roller 1111 through a toothed belt wheel and a toothed belt, will drive the push rod 211 under the rotational support of the bearing bracket 1152 to continuously move up and down along the limit conduit 1153. The reciprocatingly moving push rod 211 will simultaneously drive the pressure rod 2111 and the lifting hopper plate 21 to move up and down. Among them, the reciprocatingly moving pressure rod 2111 will intermittently push down on the vibrating plate 2112. The vibrating plate 2112 will move downward under the compression of the vibration spring 2114 after being pushed, so that the lower plate piece will be attached to the surface of the carpet and contact the output end of the vibration motor 2113. Then, the vibration motor 2113 will conduct the vibration to the surface of the vibrating plate 2112 and then conduct it to the surface of the carpet through the vibrating plate 2112 to perform vibration treatment on the un-dried carpet, remove the cavities and air bubbles existing in the adhesive between the tufted carpet and the backing, and promote the uniform distribution of the adhesive. The reciprocatingly moving lifting hopper plate 21 will slide up and down hermetically inside the glue bin 115, and during the sliding process, it will drive the valve rod 221 to move up and down. When the valve rod 221 moves downward, it will insert the lower end into the inside of the main glue pipe 23, and use the valve rod 221 to temporarily connect the glue storage space of the glue bin 115 above the lifting hopper plate 21 with the inside of the main glue pipe 23.The valve stem 221 inserted into the interior of the main rubber tube 23 will push the inclined surface push tube 232 towards the front and rear sides, causing the inclined surface push tube 232 to move away along the inner wall of the main rubber tube 23. The moving inclined surface push tube 232 will drive the piston rod 231 to move. During the movement of the piston rod 231, the glue liquid inside the glue bin 115 will be suctioned, causing the glue liquid to enter the main rubber tube 23 and flow into the interior of the inclined surface push tube 232. During this process, since the movement of the piston rod 231 will push the glue pushing cone 234 to move, and the glue pushing cone 234 will squeeze the glue liquid stored inside the space isolated by the spring limiting plate 233 at the front and rear ends of the main rubber tube 23, causing some glue liquid to further enter the interior of the paste surface glue channel 239 under the action of the thrust, ensuring that the surface where the cutter 238 contacts the carpet during cutting has sufficient glue liquid. Then, the glue pushing cone 234 will contact the upper end of the push cutting rod 236 and push the push cutting rod 236 to compress the retracting spring 237 and move downward. The downward moving push cutting rod 236 will push the cutter 238 to move downward. Then, the cutter 238, in cooperation with the glue liquid filled in the paste surface glue channel 239, will cut and apply glue to the front and rear fringes of the carpet, avoiding the situation of the cut side splitting open. When the lifting hopper plate 21 moves upward, it will drive the valve stem 221 to move upward. Then, the lower end of the valve stem 221 will be withdrawn from the interior of the main rubber tube 23 and reinserted into the interior of the connecting branch pipe 22, disconnecting the connection between the glue bin 115 and the main rubber tube 23. Due to the removal of the valve stem 221, the inclined surface end of the inclined surface push tube 232 is no longer pushed towards the front and rear sides. Then, the piston rod 231 and the inclined surface push tube 232 will return to their initial positions under the reset action of the spring limiting plate 233. During the process of the piston rod 231 and the inclined surface push tube 232 in the main rubber tube 23 moving towards each other and resetting, the glue liquid between them will be squeezed. Due to the increase in pressure, it will reach the opening pressure of the one-way valve inside the piston rod 231. Then, the one-way valve inside the piston rod 231 will open, causing the glue liquid to enter the hole channel opened inside the piston rod 231 through the one-way valve and flow along the hole channel into the spaces isolated by the spring limiting plate 233 at the front and rear ends of the main rubber tube 23, thereby replenishing the glue liquid. Then, the glue liquid stored at both ends of the main rubber tube 23 will actively flow into the interior of the paste surface glue channel 239 due to the replenishment of the glue liquid, replenishing the glue liquid in the paste surface glue channel 239 and ensuring that the cutter 238 has the condition of applying glue to the cutting surface during cutting. Then, after the carpet is trimmed, it will continue to be conveyed to the right under the conveyance of the conveying roller 1111 to the lower part of the heat drying assembly 114, and after being subjected to high-temperature drying and shaping for a specified time under the heat drying assembly 114, it will be output under the auxiliary conveyance of the guide roller 112 at the output port of the right-side feeding channel 111. The above process will continue during the carpet production process until the carpet production is completed.,

[0056] It should be noted that when applying glue with the glue rolling assembly 12, it is necessary to select a suitable glue according to the performance requirements of the carpet and the materials of the base fabric and the pile yarn, and mix it according to a certain formula. Common glues include styrene-butadiene latex, natural latex, polyurethane adhesives, etc. During the mixing process, it is necessary to strictly control parameters such as the component ratio, viscosity, and drying time of the glue to ensure that the glue can form a uniform and firm glue layer on the back of the carpet; the glue application amount needs to be adjusted according to factors such as the thickness of the carpet, the pile density, and the material of the base fabric.
