Description

Technical Field

[0001] This application relates to the technical field of bamboo product processing, and in particular to an apparatus for joining bamboo strips into a disc. Background Technology

[0002] In the bamboo strip production process, in order to join individual bamboo strips into a whole strip, it is usually necessary to initially fix and connect the bamboo strips into a strip by means of non-woven fabric bonding or thin thread connection at the bottom of the bamboo strips, and then roll them into a coil for subsequent weaving processing.

[0003] Currently, the common methods for forming bamboo strips into coils are manual rolling and mechanical rolling. Manual rolling involves manually injecting glue and manually rolling the bamboo strips by rotating the coiling and winding shaft. Its advantage is that the cost is low, but its disadvantage is that it is highly dependent on the operator's experience, and it cannot guarantee the glue effect and uniform rolling of the bamboo strips, resulting in a high product defect rate and low processing efficiency. Utility Model Content

[0004] In order to achieve rapid and stable splicing of bamboo strips, this application provides a device for splicing bamboo strips into coils.

[0005] The device for joining bamboo strips into discs provided in this application adopts the following technical solution: An apparatus for joining bamboo strips into coils includes a frame, an unwinding reel, a glue storage box, a glue-impregnating guide roller, a first pressure roller, a pressing guide roller, and a take-up reel. The unwinding reel and the take-up reel are respectively disposed at both ends of the frame along its length. A drive source for driving the unwinding reel and the take-up reel to rotate is provided on the frame. The glue storage box is disposed on the frame, the glue-impregnating guide roller is disposed in the glue storage box, the pressing guide roller is disposed on the frame, the first pressure roller is disposed on the frame and located above the pressing guide roller, and the pressing guide roller is disposed between the glue storage box and the take-up reel.

[0006] By adopting the above technical solution, the non-woven fabric strips are unwound by the unwinding wheel. Guided by the glue-impregnating guide wheel, the non-woven fabric strips are immersed in the glue solution in the glue storage box for coating. The glued non-woven fabric and the single bamboo strips simultaneously pass through the gap between the first pressure roller and the pressing guide roller for pressing together. The pressed non-woven fabric and bamboo strips are then wound onto the take-up wheel, achieving the winding of the bamboo strips. Through the coordinated operation of the frame, unwinding wheel, glue storage box, glue-impregnating guide wheel, first pressure roller, pressing guide roller, and take-up wheel, the machine achieves a rapid and stable splicing process for bamboo strips.

[0007] Optionally, a pre-tension guide wheel is provided on the vertical side wall of the end of the frame where the unwinding wheel is located, and the pre-tension guide wheel is located above the unwinding wheel.

[0008] By adopting the above technical solution, the pre-tensioning guide roller and the unwinding roller cooperate with each other to realize the pre-tensioning operation of the non-woven fabric material, reducing the possibility of excessive shrinkage of the non-woven fabric causing the bamboo strips to bend or crack during the subsequent pressing process.

[0009] Optionally, the frame is provided with a mounting bracket, and a lifting block is vertically slidably connected to the mounting bracket. The first pressure roller is rotatably mounted on the lifting block. An adjusting cylinder is provided on the mounting bracket, and the output shaft of the adjusting cylinder extends vertically downward and is connected to the lifting block in a transmission manner.

[0010] By adopting the above technical solution, and in response to different processing needs and bamboo strips of different thicknesses, the distance between the first pressure roller and the pressing guide roller can be adjusted by adjusting the cylinder to drive the lifting block to move in the vertical direction, thereby expanding the applicability of the device.

[0011] Optionally, the peripheral wall of the pressing guide wheel is provided with a plurality of pressing holes.

[0012] By adopting the above technical solution, when the pressing guide roller presses the non-woven fabric and bamboo strips, the air between the non-woven fabric and bamboo strips is discharged through the pressing hole, which helps to improve the stability of the pressing and improve the processing quality of the bamboo strips.

[0013] Optionally, a scraper is provided on the frame, and one side of the scraper is fitted against the peripheral wall of the pressing guide wheel.

[0014] By adopting the above technical solution, the scraper removes the glue adhering to the pressing guide roller, reducing the possibility that excessive glue adhering to the pressing guide roller will affect subsequent pressing operations.

[0015] Optionally, a drying assembly is provided between the first pressure roller and the take-up roller. The drying assembly includes a drying fan, an air supply pipe, a drying pipe, and drying nozzles. The drying pipe is mounted on the frame and is arranged parallel to the take-up roller. One end of the air supply pipe is connected to the drying fan, and the other end is connected to the drying pipe. Several drying nozzles are connected to the side of the drying pipe near the material conveying direction.

[0016] By adopting the above technical solution, the pressed bamboo strips are dried by the drying assembly. The drying fan is started, and the airflow is blown onto the bamboo strips through the air supply pipe, drying pipe and drying nozzle, so that the glue is dried faster and the bamboo strips are easier to store in subsequent operations.

[0017] Optionally, the frame is provided with an extension plate at one end where the take-up reel is located. A guide rod is provided on the extension plate parallel to the take-up reel. A movable block is slidably provided on the guide rod. A guide sleeve is rotatably sleeved on the movable block. The extension plate is provided with a driving component for driving the movable block to move along the length direction of the guide rod.

[0018] By adopting the above technical solution, the pressed bamboo strips are guided by the guide sleeve and wound onto the winding wheel. The guide sleeve moves back and forth under the driving action of the drive component, so that the bamboo strips can be evenly wound around various positions on the winding wheel, thus achieving uniform winding of the bamboo strips.

[0019] Optionally, each of the two opposite sides of the pressing guide wheel is connected to a limiting end plate, and the first pressing wheel is sandwiched between the two limiting end plates.

[0020] By adopting the above technical solution, the limiting end plate limits and aligns the non-woven fabric and bamboo strips, making it easier for the two to be aligned and stably bonded.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the frame, unwinding roller, glue storage box, glue-impregnating guide roller, first pressure roller, pressing guide roller and winding roller, it can achieve the effect of fast and stable splicing of bamboo strips; 2. The scraper removes the adhesive adhering to the pressing guide roller, reducing the possibility that excessive adhesive on the pressing guide roller will affect subsequent pressing operations; 3. The limiting end plate limits and aligns the non-woven fabric and bamboo strips, making it easier for them to be aligned and bonded stably. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be further described in detail below. Embodiments of this application provide a device for splicing bamboo strips into coils, which achieves the effect of rapid and stable splicing of bamboo strips.

[0027] Reference Figure 1 A device for joining bamboo strips into coils includes a frame 1, an unwinding roller 2, a winding roller 3, a drying assembly 4, a first pressure roller 5, and a second pressure roller 6. One end of the frame 1 along its length is the feed end, and the other end is the discharge end. The unwinding roller 2 is rotatably mounted on the vertical side wall of the feed end of the frame 1, and the winding roller 3 is rotatably connected to the vertical side wall of the discharge end of the frame 1. A drive source is provided on the frame 1 to drive the rotation of the winding roller 3 and the unwinding roller 2.

[0028] Reference Figure 1 A pre-tension guide wheel 7 is provided on the vertical side wall of the feed end of the frame 1. The pre-tension guide wheel 7 is positioned above and parallel to the unwinding wheel 2. A glue storage box 8 is provided on the frame 1. A glue-impregnating guide wheel 9 is rotatably mounted in the glue storage box 8. The glue-impregnating guide wheel 9 is positioned parallel to the unwinding wheel 2.

[0029] Reference Figure 1 and Figure 2 The frame 1 is equipped with a pressing guide wheel 10, which is located on the side of the glue storage box 8 near the discharge end of the frame 1. The pressing guide wheel 10 is parallel to the glue-impregnating guide wheel 9. A limiting end plate 11 is provided on each opposite side of the pressing guide wheel 10. Several pressing holes 12 are evenly spaced along the circumferential direction on the peripheral wall of the pressing guide wheel 10. The frame 1 is equipped with a mounting frame 13, on which an adjusting cylinder 14 is mounted. The output shaft of the adjusting cylinder 14 extends vertically downward and is connected to a lifting block 15. The first pressing wheel 5 is rotatably connected to the lifting block 15. The first pressing wheel 5 is located above and parallel to the pressing guide wheel 10, and is sandwiched between the two limiting end plates 11.

[0030] Reference Figure 2 and Figure 3The second pressure roller 6 is arranged parallel to the first pressure roller 5 on the frame 1, and is located on the side of the first pressure roller 5 near the discharge end of the frame 1. An extension plate 16 is connected to the discharge end of the frame 1. A guide rod 17 and a drive screw 18 are arranged parallel to each other on the extension plate 16, with the guide rod 17 parallel to the central axis of the take-up roller 3. A drive motor 20 is mounted on the extension plate 16, and the output shaft of the drive motor 20 is connected to one end of the drive screw 18. A moving block 22 is threaded onto the drive screw 18, and the guide rod 17 passes through and slides through the moving block 22. A guide sleeve 19 is rotatably mounted on the moving block 22, and the width of the guide sleeve 19 is smaller than the width of the take-up roller 3. A scraper 21 is mounted on the frame 1, with one side of the scraper 21 fitting against the peripheral wall of the pressing guide roller 10.

[0031] Reference Figure 1 and Figure 3 The drying assembly 4 is disposed between the take-up roller 3 and the second pressure roller 6. The drying assembly 4 includes a drying fan 41, an air supply pipe 42, a drying pipe 43, and drying nozzles 44. The output end of the drying fan 41 is connected to one end of the air supply pipe 42. Two drying pipes 43 are arranged in parallel on the air supply pipe 42. Several drying nozzles 44 are arranged on the side of the two drying pipes 43 that are close to each other.

[0032] Reference Figure 1 and Figure 2 During processing, the unwinding roller 2 unwinds the non-woven fabric. The non-woven fabric is stretched by the pre-tensioning guide roller 7, reducing the possibility of bamboo strips cracking due to shrinkage during subsequent operations. The pre-stretched non-woven fabric is then immersed in glue in the glue storage box 8 under the guidance of the glue-impregnating guide roller 9. The glued non-woven fabric and individual bamboo strips pass simultaneously between the first pressure roller 5 and the pressing guide roller 10 under the limiting end plate 11, achieving pressing together. During pressing, air between the non-woven fabric and bamboo strips is discharged through the pressing hole 12, improving the connection stability. The glue scraper 21 scrapes off the glue adhering to the pressing guide roller 10, reducing the possibility of glue affecting subsequent pressing processes. For bamboo strips of different thicknesses and different pressing strength requirements, the adjusting cylinder 14 drives the lifting block 15 to move vertically, adjusting the distance between the first pressure roller 5 and the pressing guide roller 10.

[0033] Reference Figure 1 and Figure 3The glued bamboo strips pass under the second pressure roller 6 and through two drying pipes 43. The drying fan 41 is started, and the airflow passes through the air supply pipe 42, the drying pipes 43, and several drying nozzles in sequence to dry the bamboo strips, making them dry faster and easier to store later. After being dried, the bamboo strips are guided by the guide sleeve and finally wound onto the take-up roller 3. The drive motor 20 drives the drive screw 18 to rotate reciprocally, causing the moving block 22 to move reciprocally along the guide rod 17, so that the bamboo strips can be evenly wound onto the take-up roller 3.

[0034] The implementation principle of the device for joining bamboo strips into a disc in this application embodiment is as follows: During processing, the unwinding wheel 2 unwinds the non-woven fabric. The non-woven fabric is stretched by the pre-stretching guide wheel 7, reducing the possibility of the bamboo strips cracking due to shrinkage of the non-woven fabric in subsequent operations. The pre-stretched non-woven fabric is immersed in the glue in the glue storage box 8 under the guidance of the glue-impregnating guide wheel 9. The glue-coated non-woven fabric and the single bamboo strip pass simultaneously between the first pressure wheel 5 and the pressing guide wheel 10 under the limiting end plate 11, realizing the pressing of the two. During pressing, the air between the non-woven fabric and the bamboo strip is discharged through the pressing hole 12, improving the connection stability between the two. The glue scraper 21 scrapes off the glue adhering to the pressing guide wheel 10, reducing the possibility of the glue affecting the subsequent pressing process. To accommodate bamboo strips of different thicknesses and different pressing strength requirements, the adjusting cylinder 14 drives the lifting block 15 to move vertically, thereby adjusting the distance between the first pressing roller 5 and the pressing guide roller 10.

[0035] Referring to the diagram, the glued bamboo strips pass under the second pressure roller 6 and through two drying pipes 43. The drying fan 41 is started, and the airflow passes sequentially through the air supply pipe 42, the drying pipes 43, and several drying nozzles to dry the bamboo strips, facilitating faster drying and subsequent storage. After drying, the bamboo strips are guided by the guide sleeve and finally wound onto the take-up roller 3. The drive motor 20 drives the drive screw 18 to rotate reciprocally, causing the moving block 22 to move reciprocally along the guide rod 17, so that the bamboo strips can be evenly wound onto the take-up roller 3.

[0036] 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.
