Description

Technical Field

[0001] This utility model relates to the field of carpet processing technology, specifically to a gluing device for carpet production. Background Technology

[0002] Carpets not only make people feel comfortable when walking and prevent slipping, but also have the effects of sound absorption, noise reduction and heat insulation. In the production process, after the carpet is woven, a semi-finished carpet is obtained. The next step is to evenly apply carpet adhesive to the semi-finished carpet so that it can be combined with the subsequent carpet fabric.

[0003] Chinese Patent CN222842425U discloses a gluing device for carpet processing, relating to the field of carpet processing technology. The device includes a frame with a gluing roller rotatably connected to its inner side. The transmission mechanism includes a transmission unit and a brushing unit; the transmission unit provides thrust for the reciprocating movement of the brushing unit. This invention, through its transmission mechanism, allows for a small-scale gluing operation on the bottom of the carpet using the gluing roller. Simultaneously, the rotating gluing rod drives the toothed ring to reciprocate, pushing a guide rod. The guide rod, through a wire groove, provides thrust to the brush rod, which then performs a secondary coating on the already coated carpet bottom, ensuring uniform coating and further improving product quality.

Detailed Implementation

[0015] Example 1, as Figures 1 to 5As shown, this utility model proposes a carpet gluing device, including a frame 1, a pressure roller 204, a glue tank 3, a gluing roller 4, and an adjustment mechanism. A U-shaped base 201 is mounted on the top of the frame 1 via a lifting component 2. The lifting component 2 is a hydraulic rod equipped with a displacement sensor for real-time monitoring of the lifting distance. A pressure sensor is installed at the connection between the lifting component 2 and the U-shaped base 201 to monitor the pressure applied by the pressure roller 204 to the carpet on the gluing roller 4, preventing insufficient or excessive pressure from affecting the gluing effect. The pressure roller 204 is detachably mounted on the U-shaped base 201 and driven to rotate by a servo motor mounted on the U-shaped base 201. The glue tank 3 is mounted on the inner wall of the frame 1 via a bracket, and two sets of channels are symmetrically opened on the glue tank 3. The gluing roller 4 is mounted on a U-shaped base 204 via a servo motor mounted on the U-shaped base 201. A servo motor drives the rotation of the outer wall of the frame 1. The two ends of the coating roller 4 pass through the corresponding channels on the glue box 3 and are rotatably connected to the frame 1 through bearings. An adjustment mechanism is installed between the glue box 3 and the coating roller 4. The adjustment mechanism includes a protective box 301, a drive assembly, and a movable seat. The protective box 301 is detachably installed at the bottom of the glue box 3. The drive assembly is located in the protective box 301. Two sets of movable seats are provided. The two sets of movable seats are symmetrically and detachably installed on the coating roller 4. Both sets of movable seats are connected to the output end of the drive assembly. The two sets of movable seats are driven by the drive assembly to slide closer to or further away from the axis of the coating roller 4 for adjustment. The inner wall of the movable seat is in contact with the outer circumference of the coating roller 4, and the outer wall of the movable seat is in contact with the inner wall of the glue box 3. Rubber seats 603 are detachably installed on both the inner and outer walls of the movable seat.

[0016] Furthermore, the U-shaped seat 201 is U-shaped, and two sets of guide arms are symmetrically installed on the U-shaped seat 201. The guide arms are slidably connected to the guide grooves on the side wall of the frame 1 to improve the lifting stability of the U-shaped seat 201.

[0017] Furthermore, two sets of rotating shafts 202 are rotatably connected to both ends of the U-shaped seat 201 via bearings. One set of rotating shafts 202 is connected to the output end of a servo motor mounted on the U-shaped seat 201. The rotating shafts 202 are provided with mounting grooves 203. Both ends of the pressure roller 204 are integrally formed with mounting seats 205. The mounting seats 205 are slidably inserted into the corresponding mounting grooves 203, and the mounting seats 205 and the mounting grooves 203 are fixed by fastening bolts. Protective pads are provided at the insertion points of the mounting seats 205 and the mounting grooves 203 to further improve the connection stability. The mounting seats 205 and the pressure rollers 204 are prefabricated in various models and can be disassembled and used according to the width of the carpet.

[0018] Furthermore, a sliding groove is provided on one side of the inner wall of the glue box 3, and a slider 602 is installed on the movable seat accordingly. The slider 602 is slidably connected to the sliding groove to improve the adjustment stability of the movable seat.

[0019] Furthermore, the drive assembly includes a dual-axis motor 5, a threaded rod 501, and a slide rod 502. The dual-axis motor 5 is installed inside the protective housing 301. Two sets of threaded rods 501 are provided, and the two sets of threaded rods 501 are respectively connected to the two output ends of the dual-axis motor 5. A reducer is provided between the dual-axis motor 5 and the threaded rods 501. The two sets of threaded rods 501 are symmetrically distributed in the protective housing 301. The end of the threaded rod 501 away from the dual-axis motor 5 is rotatably connected to the protective housing 301 through a bearing. Two sets of slide rods 502 are provided, and the two sets of slide rods 502 are symmetrically slidably connected to the protective housing 301. One end of the slide rod 502 extends into the protective housing 301 and is threadedly connected to the outer wall of the corresponding threaded rod 501.

The other end of the transmission rod 503 is detachably connected to the corresponding movable seat on the outer wall of the coating roller 4.

[0020] In this embodiment, an appropriate amount of glue is fed into the glue tank 3 through the upper section of the feed pipe on the side wall, so that the bottom of the outer circumference of the coating roller 4 is immersed in the glue to a suitable depth. In actual production, the appropriate depth value can be obtained through adjustment, so that the glue is located between the two sets of moving seats and the inner cavity of the glue tank 3. A liquid level sensor is set in the middle of the glue tank 3 to detect the amount of glue inside. According to the width of the carpet to be processed, the controller starts the dual-axis motor 5 to drive the two sets of threaded rods 501 to rotate synchronously. The controller controls the output speed and torque of the two output ends of the dual-axis motor 5 to be consistent. Through the threaded transmission, the two sets of sliding rods 502 slide along the protective box 301. The sliding rods 502 push the two sets of moving seats to move along the axis of the coating roller 4 through the transmission rod 503 until the distance between the two sets of moving seats matches the width of the carpet. Then, according to the width of the carpet, a pressure roller 204 of appropriate size is selected, and the mounting seat 205 at the end of the pressure roller 204 is inserted into the mounting groove 203 and locked. Tightening the bolts limits and fixes the position, ensuring the length of the pressure roller 204 matches the distance between the two sets of moving seats. Based on the carpet thickness, the controller activates the lifting mechanism 2 to adjust the height of the U-shaped seat 201, ensuring the distance between the pressure roller 204 and the glue-applying roller 4 matches. A pressure sensor monitors the pressure of the pressure roller 204 in real time to ensure it remains within a reasonable range. The semi-finished carpet is fed between the glue-applying roller 4 and the pressure roller 204. The controller activates the servo motors on the outer wall of the frame 1 and the U-shaped seat 201. The servo motors on the outer wall of the frame 1 drive the glue-applying roller 4 to rotate, and the servo motors on the U-shaped seat 201 drive the pressure roller 204 to rotate. The pressure roller 204, in conjunction with the glue-applying roller 4, conveys the semi-finished carpet forward. The glue in the glue box 3 adheres to the surface of the glue-applying roller 4. During the rotation of the glue-applying roller 4, the glue is evenly applied to the bottom surface of the semi-finished carpet. The rubber seat 603 on the moving seat prevents glue leakage from both ends of the glue-applying roller 4, avoiding waste of raw materials.

[0021] Example 2, as Figure 3 and Figure 5As shown, the present invention proposes a carpet production gluing device. Compared with Embodiment 1, the movable seat includes a scraper 6 and a connecting seat 601. The scraper 6 is slidably connected to the inner wall of the glue box 3. The connecting seat 601 is detachably installed on the transmission rod 503. The connecting seat 601 is opposite to the scraper 6 and is limited and fixed by fastening bolts. The slider 602 is detachably connected to the connecting seat 601 by bolts. The inner wall of the connecting seat 601 and the inner wall of the scraper 6 are adapted to the outer peripheral surface of the glue roller 4. The inner wall of the connecting seat 601, the inner wall of the scraper 6, and the outer wall of the scraper 6 can all be detachably installed with a suitable rubber seat 603.

[0022] In this embodiment, the connecting seat 601 can be disassembled by unscrewing the bolts between the connecting seat 601 and the transmission rod 503, the connecting seat 601 and the scraper 6, and the slider 602 and the connecting seat 601. Then, the scraper 6 is tilted down along the inner wall of the glue box 3 to compress the corresponding rubber seat 603, so that the scraper 6 can be laid down relative to the glue box 3. The scraper 6 can then be removed from between the glue roller 4 and the glue box 3, and the worn rubber seats 603 can be disassembled, replaced and maintained. The operation is convenient.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
