Description

Technical Field

[0001] This application relates to the field of carpet production equipment technology, and in particular to an adjustable carpet nail chain conveyor. Background Technology

[0002] In carpet manufacturing, the drying process after adhesive application is a crucial step, directly impacting the quality and performance of the final product. With increasing market demand, carpet production lines are increasingly moving towards large-scale, high-efficiency operations, placing higher demands on drying equipment. Traditional drying equipment typically exceeds 20 meters in length. During long-distance transport, carpets are susceptible to displacement or wrinkling due to hot air disturbance or their own weight, affecting the uniformity of adhesive curing. To address this challenge, various technologies have emerged in the industry, striving to improve production efficiency while ensuring quality.

[0003] To address the issue of carpet fixation during the drying process, existing technologies primarily employ methods such as mechanical clamping, vacuum adsorption, and tension control. Mechanical clamping uses pneumatic or electric grippers to hold the carpet edges, with servo motors enabling width adjustment; however, its adaptability is poor, making it difficult to meet the demands of continuous mass production. Vacuum adsorption utilizes a porous platform and a vacuum pump to provide stable adsorption force; while effective, the equipment cost is high, with initial investment reaching hundreds of thousands of yuan. Tension control relies on a servo motor driving an active roller to apply appropriate tension, combined with infrared temperature feedback to adjust parameters; however, it can easily cause stretching deformation in thinner carpets. Furthermore, positioning groove technology uses a silicone conveyor belt to press positioning grooves for fixation, but this requires pre-punching of the carpet, adding extra steps and increasing the scrap rate.

[0004] The aforementioned conventional methods all have significant shortcomings. Mechanical clamping methods are inadequate for large-scale continuous production; while vacuum adsorption is highly effective, its high cost limits its widespread application; tension control is poorly suited to thin carpets; and positioning grooves require additional punching processes, reducing production efficiency and increasing scrap rates. Therefore, how to effectively prevent carpet shifting or wrinkling during the drying process while ensuring low costs has become an urgent technical challenge. Utility Model Content

[0005] To improve the stability of carpet transport during the drying process, this application provides an adjustable carpet nail chain conveyor.

[0006] The adjustable carpet nail chain conveyor provided in this application adopts the following technical solution:

[0007] An adjustable carpet nail chain conveying device includes two parallel conveyor frames arranged along the carpet conveying direction. Each conveyor frame is equipped with an annular conveyor rail. Several support chain plates are slidably arranged on the conveyor rail. A drive chain is hinged between two adjacent support chain plates. The several support chain plates form a chain structure connected end to end through the drive chain. The outer wall of the support chain plate is provided with a nail plate for fixing carpet scraps. A sprocket is coaxially rotatably arranged on the conveyor frame near the arc-shaped end of the conveyor rail. The sprocket meshes with the drive chain for transmission. The conveyor frame is also equipped with a conveyor motor for driving the sprocket to rotate. A nail pressing assembly is raised and lowered on the top of the two conveyor frames. The nail pressing assembly includes a rotating motor and a pressure roller coaxially connected to the output shaft of the rotating motor. The two pressure rollers are arranged opposite each other for pressing the carpet scraps into the nail plate.

[0008] By adopting the above technical solution, during the carpet conveying process, the waste edges are first pressed and embedded into the nail plates by the pressure rollers in the nailing assembly. The nail plates are located on the outer wall of the support chain plates, which can firmly fix the waste edges of the carpet. Subsequently, the drive chain drives several support chain plates to form a chain structure connected end to end. Under the meshing transmission of the sprocket and the drive chain, the conveyor motor drives the smooth conveying. The parallel conveyor frames on both sides ensure the stability of the entire device. This design not only effectively solves the problems of carpet displacement and wrinkling caused by hot air disturbance or its own gravity during the drying process, but also improves the stability and reliability of carpet conveying, thereby ensuring the uniform curing of the adhesive layer and improving the quality and performance of the final product.

[0009] Optionally, the inner side of the transmission guide rail is provided with a clearance groove, which is used to accommodate the tooth tip of the sprocket and allow the sprocket to push the drive chain to move.

[0010] By adopting the above technical solution, the design of the clearance groove can effectively reduce the possibility of interference between the sprocket tooth tip and the transmission guide rail, thereby improving the smoothness of the sprocket driving the drive chain, and thus improving the stability of the transmission and reducing mechanical wear.

[0011] Optionally, a fixing hook plate is provided on the outer side wall of the support chain plate along its own length direction, and the nail plate is inserted into the fixing hook plate and fixed by bolts.

[0012] By adopting the above technical solution, the fixed hook plate forms an insertion space, which not only facilitates the quick installation and removal of the nail plate, but also reduces the possibility of the nail plate loosening or falling off when subjected to external force.

[0013] Optionally, a number of ball bearings are embedded in the side wall of the support chain plate that fits against the conveyor rail.

[0014] By adopting the above technical solution, the embedding of ball bearings can improve the running stability of the support chain plate on the conveyor rail, reduce the occurrence of shaking or jamming caused by uneven friction, thereby improving the stability of the blanket during the conveying process and enhancing the overall transmission efficiency and reliability.

[0015] Optionally, the outer ring of the pressure roller is provided with a nail ring for cleaning up loose fibers from the carpet edges.

[0016] By adopting the above technical solution, during the carpet conveying process, when the nail ring comes into contact with the carpet waste edge, its special structure combs and removes the loose fibers, thereby reducing the interference of loose fibers with the subsequent drying process and improving the cleanliness and stability of carpet conveying.

[0017] Optionally, the bottom of the conveyor frame is provided with multiple support legs, each support leg is equipped with a moving wheel at its bottom end, the opposite sides of the two conveyor frames are provided with fixed plates, a guide rod is connected between the two fixed plates, the bottom of each conveyor frame is provided with a slider that is slidably sleeved on the guide rod, and a distance adjustment component for adjusting the distance between the two fixed plates is provided.

[0018] By adopting the above technical solution, the conveyor frame utilizes casters to achieve flexible movement of the entire device. When it is necessary to adjust the distance between two conveyor frames, the slider is driven by the distance adjustment component to slide along the guide rod, thereby causing the two conveyor frames to move relative to or away from each other, thus completing the distance adjustment. This design not only facilitates the overall handling and installation of the equipment, but also allows for flexible adjustment of the distance between the conveyor frames according to actual production needs, to adapt to the conveying requirements of carpets of different widths.

[0019] Optionally, the pitch adjustment assembly includes a bidirectional screw and a servo motor. The bidirectional screw is parallel to the guide rod and is rotatably disposed between two fixed plates. The slider corresponds one-to-one with the threaded section of the bidirectional screw and is sleeved on the threaded section of the bidirectional screw through thread rotation. The output shaft of the servo motor is coaxially connected to the bidirectional screw.

[0020] By adopting the above technical solution, a servo motor drives a bidirectional screw to rotate, causing the slider to move smoothly along the guide rod, thereby achieving precise adjustment of the distance between the two conveyor frames. This allows for rapid adaptation to different production needs based on carpet width, effectively improving the equipment's versatility and production efficiency.

[0021] Optionally, a fixed base is provided at the center of the two fixed plates. The adjustable distance assembly includes a brake motor vertically mounted on the fixed base, a winding wheel sleeved on the output shaft of the brake motor, and a pull rope connecting the winding wheel and the slider. Earrings are provided on opposite sides of the two fixed plates. Each slider is connected to the winding wheel with two pull ropes. The fixed end of one pull rope is connected to the side wall of the slider facing the winding wheel, and the free end is wound around the winding wheel. The fixed end of the other pull rope is connected to the side wall of the slider away from the winding wheel, and the free end passes through the earring and is wound around the winding wheel. The two pull ropes on the same winding wheel have opposite winding directions. When the brake motor drives the winding wheel to rotate clockwise, the winding wheel winds up the pull rope on the side of the slider close to the winding wheel and unwinds the pull rope on the side of the slider away from the winding wheel. At this time, the two conveyor frames move relative to each other along the guide rod.

[0022] By adopting the above technical solution, when the brake motor drives the rotating reel to rotate, the sliding block moves stably along the guide rod by retracting and extending the pull rope, thereby driving the two conveyor frames to move relative to or away from each other. This not only simplifies the adjustment structure but also improves the controllability and reliability of the adjustment process, making it suitable for the transmission needs of carpets of different widths and effectively enhancing the adaptability and production efficiency of the equipment.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. During the carpet conveying process, the waste edges are first pressed and embedded into the nail plates by the pressure rollers in the nailing assembly. The nail plates are located on the outer wall of the support chain plates, firmly securing the waste edges. Subsequently, the drive chain drives several support chain plates to form a chain structure connected end-to-end. Driven by the conveyor motor, the conveyor is smoothly transported through the meshing transmission of the sprockets and drive chain. Parallel conveyor frames on both sides ensure the stability of the entire device. This design not only effectively solves the problems of carpet displacement and wrinkling caused by hot air disturbance or its own weight during drying, but also improves the stability and reliability of carpet conveying, thereby ensuring uniform curing of the adhesive layer and improving the quality and performance of the final product.

[0025] 2. The design of the clearance groove can effectively reduce the possibility of interference between the sprocket tooth tip and the transmission guide rail, thereby improving the smoothness of the sprocket driving the drive chain, thus improving the stability of the transmission and reducing mechanical wear;

[0026] 3. The use of two parallel fixed hook plates to form an insertion space not only facilitates the quick installation and removal of the nail plate, but also reduces the possibility of the nail plate loosening or falling off when subjected to external forces. Attached Figure Description

[0035] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0036] This application discloses an adjustable carpet nail chain conveying device.

[0037] Example 1

[0038] Reference Figure 1 and Figure 2An adjustable carpet nail chain conveying device includes a conveyor frame 1, with two conveyor frames 1 arranged parallel to each other on both sides along the carpet conveying direction. Each conveyor frame 1 has four fixed legs 11 at its bottom, and each leg 11 has a caster wheel 111 at its bottom. Fixed plates 2 are located on opposite sides of the two conveyor frames 1, and a horizontal guide rod 21 is fixedly connected between the two fixed plates 2. A slider 12 is fixedly mounted on the bottom of each conveyor frame 1 and slidably fitted onto the guide rod 21. An adjusting assembly 3 for adjusting the distance between the conveyor frames 1 is located between the two fixed plates 2. Each conveyor frame 1 has an annular conveying guide rail 4, on which a nail chain conveying mechanism 5 is slidably mounted. Nail pressing assemblies 6 are raised and lowered at the top of the two conveyor frames 1.

[0039] Reference Figure 1 and Figure 2 Before the carpet is conveyed for the drying process, the spacing between the two conveyor frames 1 is adjusted according to the width of the carpet using the spacing adjustment component 3, and then the carpet is conveyed. During the conveying process, the waste edges of the carpet are pressed into the conveying nail chain mechanism 5 by the nail pressing component 6, and are stably conveyed into the drying process along with the conveying nail chain mechanism 5 for drying.

[0040] Reference Figure 2 In this embodiment, the pitch adjustment component 3 includes a bidirectional screw 31 and a servo motor 32. The bidirectional screw 31 is parallel to the guide rod 21 and is rotatably disposed between two fixed plates 2. The slider 12 corresponds one-to-one with the threaded section of the bidirectional screw 31 and is sleeved on the threaded section of the bidirectional screw 31 by rotating the thread. The servo motor 32 is fixedly disposed on the side wall of one of the fixed plates 2 away from the bidirectional screw 31. The output shaft of the servo motor 32 rotates through the fixed plate 2 and is coaxially fixedly connected to the bidirectional screw 31.

[0041] Reference Figure 3 The conveying chain mechanism 5 includes a support chain plate 51, a drive chain 52, and a nail plate 53. Several support chain plates 51 are slidably arranged along the trajectory of the conveying guide rail 4. The drive chain 52 is hinged between two adjacent support chain plates 51. Several support chain plates 51 form a chain structure connected end to end through the drive chain 52. The inner side of the conveying guide rail 4 is recessed with a relief groove 41. A sprocket 13 is coaxially rotatably arranged on the conveying frame 1 near the arc-shaped end of the conveying guide rail 4. The sprocket 13 meshes with the drive chain 52 for transmission. A conveying motor 131 is fixedly arranged at the bottom of the conveying frame 1. The output shaft of the conveying motor 131 rotatably passes through the conveying frame 1 and is coaxially fixedly connected with the sprocket 13.

[0042] Reference Figure 3A fixing hook plate 511 is fixedly installed on the outer side wall of the supporting chain plate 51 along its own length direction. The nail plate 53 is inserted into the fixing hook plate 511 and the fixing hook plate 511 and nail plate 53 are fixed by bolts.

[0043] Reference Figure 3 In order to reduce the friction between the support chain plate 51 and the conveyor rail 4, a number of balls 7 are embedded on the side wall of each support chain plate 51 that is in contact with the conveyor rail 4.

[0044] Reference Figure 1 and Figure 4 The pressing assembly 6 is located at the entry end of the two conveyor frames 1, and a vertical guide post 14 is fixedly installed on the top of the conveyor frame 1. A lifting plate 141 is slidably sleeved on the guide post 14, and a vertically arranged cylinder 15 is installed on the lifting plate 141 and the conveyor frame 1. The pressing assembly 6 includes a rotating motor 61 and a pressing roller 62. The rotating motor 61 is fixedly installed on the lifting plate 141, and its output shaft faces the adjacent conveyor frame 1 and is coaxially fixedly connected to the pressing roller 62. The pressing roller 62 is used to press the carpet waste edges into the nail plate 53, and two nail rings 621 for cleaning the loose fibers of the carpet waste edges are fixedly sleeved on the outer ring of the pressing roller 62.

[0045] The implementation principle of the adjustable carpet nail chain conveyor in this embodiment is as follows: Before the carpet is conveyed during the drying process, the servo motor 32 drives the bidirectional screw 31 to rotate according to the width of the carpet, so that the slider 12 moves smoothly along the guide rod 21, thereby achieving precise adjustment of the distance between the two conveyor frames 1, and then the carpet conveying begins. The waste edges are first pressed into the nail plate 53 by the pressure roller 62 in the nail assembly 6. The nail plate 53 is located on the outer wall of the support chain plate 51, which can firmly fix the waste edges of the carpet. Subsequently, the drive chain 52 drives several support chain plates 51 to form a chain structure connected end to end. Under the meshing transmission of the sprocket 13 and the drive chain 52, the conveyor motor 131 drives the smooth conveying into the drying process for drying. This significantly improves the transmission stability of the carpet during the drying process, reduces the scrap rate, and increases production efficiency.

[0046] Example 2

[0047] Reference Figure 5 and Figure 6The difference between this embodiment and Embodiment 1 lies in the difference in the adjusting component 3. In this embodiment, a fixed base 8 is fixedly installed at the center of the two fixed plates 2. The adjusting component 3 includes a brake motor 33, a winding wheel 34, and pull ropes 35. The brake motor 33 is fixedly installed vertically on the fixed base 8. The winding wheel 34 is fixedly sleeved on the output shaft of the brake motor 33. Earrings 22 are fixedly installed on opposite sides of the two fixed plates 2. Each slider 12 is connected to two pull ropes 35 between itself and the winding wheel 34. The fixed end of one pull rope 35 is connected to the side wall of the slider 12 facing the winding wheel 34, and the free end is wound around the winding wheel 34. The fixed end of the other pull rope 35 is connected to the side wall of the slider 12 away from the winding wheel 34, and the free end passes through the earring 22 and is wound around the winding wheel 34. The two pull ropes 35 on the same winding wheel 34 have opposite winding directions.

[0048] The implementation principle of Example 2 is as follows: According to the width of the carpet to be dried, when the brake motor 33 drives the winding wheel 34 to rotate clockwise, the winding slider 12 of the winding wheel 34 approaches the pull rope 35 on the side of the winding wheel 34, while the unwinding slider 12 moves away from the pull rope 35 on the side of the winding wheel 34. At this time, the two conveyor frames 1 move relative to each other along the guide rod 21, and vice versa. This can be adapted to the transmission needs of carpets of different widths, effectively improving the adaptability and production efficiency of the equipment.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
