Description

Technical Field

[0001] This utility model relates to the field of carpet processing technology, specifically a composite carpet backing edge rolling device. Background Technology

[0002] Composite carpets are carpets made by combining multiple materials through a specific process. They are usually composed of three layers: a top layer (fiber fabric), a middle layer (cushioning and support material), and a bottom layer (anti-slip material). During the production process of carpets, the edges of the bottom fabric may have rough edges or unevenness. At the same time, in order to prevent the bottom fabric edges from coming loose or fraying and to enhance the stability of the carpet structure, the bottom fabric needs to be rolled up.

[0003] Some manufacturers still use manual edge rolling, where workers need to manually fold and fix the edges of the carpet backing. This method is not only inefficient, but also results in inconsistent edge rolling quality due to the large differences in manual operation. Moreover, most existing edge rolling equipment has a complex structure, is inconvenient to operate, and is designed for specific carpet specifications, making it difficult to adapt well to carpet backings of different thicknesses and widths. Utility Model Content

[0004] The purpose of this invention is to provide a composite carpet backing edge rolling tool to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A composite carpet backing edge rolling tool, comprising:

[0007] The control panel has two symmetrical sliding grooves on its top surface.

[0008] Two guide units are provided, which are respectively located on the front and rear sides of the top surface of the operating table. Each guide unit includes two fixed frames, and a guide roller is rotatably connected between the two fixed frames. A second motor is fixedly connected to the outer side of one of the fixed frames, and the motor shaft of the second motor is drivenly connected to the shaft of the guide roller.

[0009] The edge-rolling unit comprises two symmetrical units, each including a mounting base. A movable block is fixedly connected to the bottom surface of each mounting base, and the movable block is slidably connected to a sliding groove. An L-shaped plate is provided on the opposite side of each mounting base, and a U-shaped mold is provided at the bottom end of each L-shaped plate. A T-shaped groove is formed on the bottom side of each L-shaped plate, and a T-shaped block is fixedly connected to the top of each U-shaped mold, with the T-shaped block interlocking with the T-shaped groove. A mounting bracket is fixedly connected to the top surface of each mounting base, and a flattening assembly is connected to the inner top surface of each mounting bracket via an electric telescopic rod.

[0010] Furthermore, each of the two outer side walls of the operating platform is equipped with a motor, and each of the two slides is rotatably connected to a lead screw. The motor shafts of the two motors are respectively connected to the two lead screws for transmission, and the two moving blocks are respectively screwed to the outer walls of the two lead screws.

[0011] Furthermore, the guide unit also includes two electric telescopic rods, the bottom ends of which are fixedly connected to the top surface of the operating table, and the top ends of which are fixedly connected to two fixed frames respectively.

[0012] Furthermore, a limiting plate is fixedly connected to the top side of the U-shaped mold.

[0013] Furthermore, the top surface of the L-shaped plate has a threaded hole and two round holes, and the opposite sidewalls of the two mounting seats have rectangular grooves. The ends of the L-shaped plate are inserted into the rectangular grooves, and two round rods are symmetrically fixedly connected inside the rectangular grooves. The two round rods are slidably inserted into the two round holes respectively. A threaded rod is rotatably connected inside the rectangular grooves, and a handwheel is fixedly connected to the top of the threaded rod extending out of the top surface of the mounting seat. The threaded rod is screwed into the threaded hole.

[0014] Furthermore, each of the two L-shaped plates has a second sliding groove on its end side above the T-shaped groove, and a baffle is slidably connected in each of the two sliding grooves.

[0015] Furthermore, the flattening assembly includes two connecting plates, three pressure rollers are rotatably connected between the two connecting plates, a top plate is provided above the pressure rollers, and connecting rods are fixedly connected between the top surface of the two connecting plates and the bottom surface of the top plate. The bottom end of the second electric telescopic rod is fixedly connected to the top surface of the top plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. Through the coordinated arrangement of the operating table, guide unit and edge-rolling unit, after the carpet backing is laid on the surface of the operating table, the two edge-rolling units are controlled to move closer to each other, so that the two U-shaped molds respectively roll the edges of the backing. The U-shaped molds complete the edge-rolling while the guide roller pulls the backing, and the flattening component then dynamically flattens the newly formed edge, which is highly efficient and easy to operate.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5In this embodiment of the present invention, a composite carpet backing fabric hemming device includes an operating table 100, a guide unit 200, and a hemming unit 300. Two symmetrical sliding grooves 110 are provided on the top surface of the operating table 100, both of which are horizontally arranged. Two guide units 200 are provided, respectively located on the front and rear sides of the top surface of the operating table 100, for driving the backing fabric to move on the surface of the operating table 100. Each guide unit 200 includes two fixed frames 210, with a guide roller 220 rotatably connected between the two fixed frames 210. A motor 230 is fixedly connected to the outer side of one of the fixed frames 210, and the motor shaft of the motor 230 is drively connected to the shaft of the guide roller 220. Two hemming units 300 are provided and symmetrically arranged, each located on a different side of the operating table 100. Between the guide units 200, the hemming unit 300 includes a mounting base 310. The bottom surfaces of the two mounting bases 310 are fixedly connected to a movable block 320, which is slidably connected to the slide groove 110. An L-shaped plate 330 is provided on the opposite side of the two mounting bases 310. A U-shaped mold 340 is provided at the bottom end of the two L-shaped plates 330. A T-shaped groove 333 is opened on the bottom side of the L-shaped plate 330. A T-shaped block 341 is fixedly connected to the top of the U-shaped mold 340. The T-shaped block 341 and the T-shaped groove 333 are interlocked. The U-shaped mold 340 is provided with different sizes and can be replaced according to the different thicknesses of the base fabric. The top surfaces of the two mounting bases 310 are fixedly connected to a mounting bracket 350. The inner top surfaces of the two mounting brackets 350 are connected to a flattening component 370 through an electric telescopic rod 360. The flattening assembly 370 is positioned near the rear. Motors 130 are mounted on both outer walls of the operating table 100. Lead screws 120 are rotatably connected inside both slide rails 110. The motor shafts of the two motors 130 are respectively connected to the lead screws 120. Two moving blocks 320 are screwed onto the outer walls of the two lead screws 120. A limit plate 342 is fixedly connected to the top side of the U-shaped mold 340 to prevent the bottom fabric from rolling up at the edge. The guide unit 200 also includes two electric telescopic rods 240. The bottom ends of both electric telescopic rods 240 are fixedly connected to the top surface of the operating table 100, and the top ends of both electric telescopic rods 240 are fixedly connected to two fixed frames 210. By controlling the extension or retraction of the electric telescopic rods 240, the guide rollers 220 can be moved up and down, thus allowing the use of carpet bottom fabrics of different thicknesses.

[0027] Specifically, the backing fabric is inserted from the front of the operating table 100, passes under the guide roller 220, and is laid on the top surface of the operating table 100. The drive motor 230 drives the guide roller 220 to rotate at a set speed through a coupling. The surface of the guide roller 220 is provided with anti-slip texture (such as rubber coating) to increase the coefficient of friction with the backing fabric, ensuring that the backing fabric is stably pulled without slipping. The two hemming units 300 move towards each other along the slide groove 110. The openings of the two U-shaped molds 340 are facing each other, and the bottom ends of the openings of the U-shaped molds 340 are provided with an inclination angle, so that when the hemming unit 300 approaches the edge of the backing fabric, the edge of the carpet backing fabric will follow the inside of the U-shaped mold 340. The groove is bent and folded upwards until the folded edge abuts against the limiting plate 342, at which point the movement of the hemming unit 300 stops. The two electric telescopic rods 360 are extended to push the flattening component 370 down to press tightly against the folded hemmed surface. At this time, the motor 230 is started to drive the guide roller 220 to rotate, which can make the carpet backing fabric conveyed straight. Its edge is guided by the groove of the U-shaped mold 340 to maintain the folded state, and is gradually flattened by the flattening component 370 as it moves. The motors 230 of the front and rear guide units 200 run synchronously, and the speed signal is fed back to the control system through the encoder to adjust the speed difference between the two rollers in real time, eliminating tension fluctuations during the conveying of the backing fabric.

[0028] like Figure 3-4 As shown, in this embodiment, the top surface of the L-shaped plate 330 has a threaded hole 331 and two round holes 332. The threaded hole 331 is located between the two round holes 332. The opposite sidewalls of the two mounting seats 310 are provided with rectangular grooves 311. The end of the L-shaped plate 330 is inserted into the rectangular groove 311. Two round rods 312 are symmetrically fixedly connected in the rectangular groove 311. The two round rods 312 are slidably inserted into the two round holes 332 respectively. A threaded rod 313 is rotatably connected inside the rectangular groove 311. The top end of the threaded rod 313 extends out of the top surface of the mounting seat 310 and is fixedly connected to a handwheel 314. The threaded rod 313 is screwed into the threaded hole 331.

[0029] In this embodiment, when different sizes of U-shaped molds 340 are replaced, the contact state between the bottom of the U-shaped mold 340 and the top surface of the operating table 100 will undergo two extreme changes. When a small-sized U-shaped mold 340 is used, its bottom is suspended due to the fixed height of the mounting base 310, which affects the smooth entry of the edge of the carpet backing into the groove of the U-shaped mold 340. When a large-sized U-shaped mold 340 is used, the reserved space is too small, resulting in mismatch in installation. Because the rotating handwheel 314 drives the threaded rod 313 to rotate, the L-shaped plate 330 is restricted from rotating by the two round rods 312, so that the L-shaped plate 330 moves up and down along the inside of the rectangular groove 311. The L-shaped plate 330 drives the U-shaped mold 340 to move vertically, so as to achieve the fit between the bottom of the U-shaped mold 340 and the top surface of the operating table 100.

[0030] like Figure 4 As shown, in this embodiment, the two L-shaped plates 330 are provided with sliding grooves 334 on their ends above the T-shaped grooves 333, and baffles 335 are slidably connected in the two sliding grooves 334.

[0031] In practice, the U-shaped mold 340 can be quickly replaced by the insertion and engagement of the T-shaped block 341 and the T-shaped groove 333. The baffle 335 is there to prevent the T-shaped block 341 from sliding out of the T-shaped groove 333 during operation. During installation, the baffle 335 is first pushed upward along the slide groove 334 to expose the T-shaped groove 333. Then, the T-shaped block 341 at the top of the U-shaped mold 340 is slid into the T-shaped groove 333 and fully inserted into the downward sliding baffle 335, so that the baffle 335 blocks the opening area of ​​the T-shaped groove 333 and limits the U-shaped mold 340.

[0032] like Figure 2 As shown, in this embodiment, the flattening assembly 370 includes two connecting plates 371, three pressure rollers 372 are rotatably connected between the two connecting plates 371, a top plate 373 is provided above the pressure rollers 372, and connecting rods 374 are fixedly connected between the top surface of the two connecting plates 371 and the bottom surface of the top plate 373. The bottom end of the electric telescopic rod 360 is fixedly connected to the top surface of the top plate 373.

[0033] In practice, the axial direction of the pressure roller 372 is the same as that of the guide roller 220. The edge of the carpet backing fabric is folded and rolled up under the action of the U-shaped mold 340. The electric telescopic rod 360 is extended to push the flattening component 370 down, so that the pressure roller 372 is in close contact with the folded edge surface. Then the guide roller 220 is restarted to drive the backing fabric to move continuously. At the same time, the pressure roller 372 rotates with the movement of the backing fabric, achieving full flattening without hindering the movement of the backing fabric.

[0034] In this invention, to facilitate operator control, a PLC controller can be provided, and motor 130, motor 230, electric telescopic rod 240 and electric telescopic rod 360 are all electrically connected to the PLC controller. The PLC controller is existing technology and will not be described in detail here.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
