Description

Technical Field

[0001] This utility model belongs to the field of automation equipment technology, and specifically relates to a curling device. Background Technology

[0002] In the fabric cutting process, after the film is laminated, the plastic padding attached to its surface needs to be peeled off. Currently, compressed air is commonly used to separate and recycle the plastic padding, but this method has the following problems: First, the blowing efficiency is low, making it difficult to meet the needs of continuous production; second, the compressed air jet generates significant noise, which can damage the hearing of operators over time, thus affecting work efficiency; and third, the high consumption of compressed air leads to significant energy waste. Furthermore, the blown-off plastic padding requires a large square collection basket for recycling, which occupies a lot of space, and the blowing path is difficult to control precisely, easily causing the plastic padding to scatter in the work area, resulting in a chaotic site. After recycling, operators still need to manually remove the plastic padding from the collection basket, which is up to 1.5 meters deep, resulting in high labor intensity and inconvenience. Utility Model Content

[0003] In view of the shortcomings of existing technologies, a curling device is proposed to solve the technical problems of low efficiency, cumbersome recycling process and high manual labor intensity in the process of separating and recycling plastic mats.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A winding device includes a drive shaft and a winding shaft, wherein the winding shaft is detachably connected to the drive shaft, the winding shaft is tapered, and two winding shafts are symmetrically arranged and interlocked to form a winding shaft assembly with a central concave portion.

[0005] The technical solution is further configured such that the winding shaft has a large-diameter end, and a baffle is provided at the end face of the large-diameter end, the diameter of the baffle being larger than the diameter of the large-diameter end.

[0006] The technical solution is further configured such that the baffle is provided with an elongated hole in the radial direction, the large-diameter end face of the winding shaft is provided with a mounting hole, and the connector passes through the elongated hole and is fixed in the mounting hole.

[0007] The technical solution is further configured such that the baffle is composed of multiple sub-baffles spliced ​​together, and the joints of adjacent sub-baffles are interlocked.

[0008] The technical solution is further configured such that a positioning sleeve is provided on the outer side of the large-diameter end of the winding shaft, the positioning sleeve is sleeved on the periphery of the transmission shaft and locked by a locking member.

[0009] The technical solution is further configured such that the winding shaft has a small diameter end, and the small diameter ends of the two winding shafts are aligned through a docking structure.

[0010] The technical solution is further configured to include a mounting bracket, wherein the first end of the drive shaft is rotatably connected to the mounting bracket via a bearing assembly, the second end of the drive shaft extends to the outside of the mounting bracket, and the coiling shaft is sleeved on the second end of the drive shaft. The technical solution is further configured such that a power element is provided on the mounting bracket, and the power output end of the power element is connected to the transmission shaft.

[0011] The beneficial effects of this utility model are: The plastic mat is wound and recycled using a coiling shaft assembly, completely eliminating the inefficient and uncontrollable compressed air blowing method. The volume of the rolled-up plastic mat is significantly reduced, which not only saves a lot of on-site storage space but also facilitates subsequent transportation and processing. In addition, the conical design of the coiling shaft makes it easier for the rolled-up plastic mat to detach from its surface, further improving unloading efficiency. Attached Figure Description

Detailed Implementation

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0015] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0016] According to an embodiment of this utility model, a curling device is provided; please refer to [link / reference]. Figures 1 to 3 The system includes a mounting bracket 600, a power element 800, a drive shaft 100, and a crankshaft assembly. The power element 800 is mounted on the mounting bracket 600, and its power output end is connected to the drive shaft 100 to drive the drive shaft 100 to rotate. The first end of the drive shaft 100 is rotatably supported on the mounting bracket 600 by a bearing assembly 700, and the second end extends outward for mounting the crankshaft assembly.

[0017] It is understandable that the coiling shaft assembly is cantilevered at the end of the drive shaft 100. This design not only ensures the unobstructed rotation space required for the coiling operation, but also provides an unloading channel for the plastic pad after it has been coiled, making the unloading operation more direct and convenient.

[0018] Optionally, the power element 800 uses an electric motor or a pneumatic motor, which completely eliminates the high-decibel compressed air jet noise and improves the working environment.

[0019] Optionally, the drive shaft 100 may be a square bar or an air shaft.

[0020] By adopting the above technical solution, after the adhesive strip is properly attached, the plastic pad on its surface is manually pulled to the winding shaft assembly. The rotation of the winding shaft assembly winds and recycles the plastic pad, completely eliminating the inefficient and uncontrollable compressed air blowing method. The volume of the rolled-up plastic pad is significantly reduced, which not only saves a lot of on-site storage space but also facilitates subsequent transportation and processing. This device is suitable for recycling components that do not have specific requirements for material shape, appearance, tension, etc., and is especially suitable for the rolling and recycling of flexible strip-shaped waste materials such as plastic pads and adhesive edges. This device aims to achieve the winding, rapid loading and unloading, and reduction of storage volume of recycled materials, thereby overcoming the defects of compressed air blowing, such as noise, energy consumption, and space waste.

[0021] In one embodiment of the present invention, a curling device is described below. Figures 1 to 3 The coiling shaft assembly includes two symmetrically arranged coiling shafts 200, which are detachably connected to the second end of the transmission shaft 100. The coiling shafts 200 are tapered, and the two coiling shafts 200 are joined together to form a coiling shaft assembly with a concave center.

[0022] Understandably, the coiled shaft assembly has a coiled surface with a small diameter in the middle and large diameters at both ends. This structure allows the coiled plastic pad to naturally gather towards the center, preventing it from easily scattering. The coiled shaft 200 is detachably connected to the drive shaft 100, allowing for quick separation after coiling and removal of the coiled plastic pad. Furthermore, the coiled shaft 200 employs a tapered design, making it easier for the coiled plastic pad to detach from its surface, further improving unloading efficiency.

[0023] In one embodiment of the present invention, a curling device is described below. Figures 1 to 3 The winding shaft 200 has a large-diameter end, and a baffle 300 is provided at the end face of the large-diameter end. The diameter of the baffle 300 is larger than the diameter of the large-diameter end.

[0024] Understandably, the baffle 300 is used to axially limit the plastic pad and optimize the curling effect. The entire device is equipped with two baffles 300, and the plastic pad (curling material) is curled in the area between the two baffles 300.

[0025] In one embodiment of the present invention, a curling device is described below. Figures 1 to 4 The baffle 300 is provided with an elongated hole 302 in the radial direction, and the large-diameter end face of the winding shaft 200 is provided with a mounting hole 201. The connector 900 passes through the elongated hole 302 and is fixed in the mounting hole 201.

[0026] Optionally, one elongated hole 302 can correspond to multiple mounting holes 201. The connector 900 uses bolts.

[0027] Understandably, the position of the connector 900 in the elongated hole 302 is not fixed, but can be continuously adjusted within a certain range. By loosening the connector 900 and replacing the baffles 300 with different diameters, the effective diameter of the device can be changed, thereby adapting to recycled materials with different curling amounts and enhancing the versatility of the device.

[0028] In one embodiment of the present invention, a curling device is described below. Figures 1 to 4 The baffle 300 is composed of multiple sub-baffles 301 spliced ​​together, and the joints of adjacent sub-baffles 301 are interlocked.

[0029] Optionally, each baffle 300 has a baffle inner hole 303 at its center, and the shape of the baffle inner hole 303 is adapted to the cross-sectional shape of the drive shaft 100. Similarly, each coil shaft 200 has a coil shaft inner hole at its center.

[0030] Optionally, the baffle 300 is composed of two sub-baffles 301 spliced ​​together. The joint of the two sub-baffles 301 is provided with a tenon and mortise joint structure, which can be aligned and fastened more quickly when the two sub-baffles 301 are fastened together.

[0031] Optionally, the baffle 300 can also be composed of three, four, or even more sub-baffles 301. Understandably, the larger the diameter of the baffle 300, the more sub-baffles 301 can be, reducing the difficulty of processing and transportation.

[0032] In one embodiment of the present invention, a curling device is described below. Figures 1 to 3 A positioning sleeve 400 is provided on the outer side of the large diameter end of the winding shaft 200. The positioning sleeve 400 is sleeved on the periphery of the transmission shaft 100 and locked by the locking member 500.

[0033] Optionally, the positioning sleeve 400 is provided with a locking hole for the locking member 500 to pass through. After the end of the locking member 500 passes through the locking hole, it abuts against the drive shaft 100 to achieve locking.

[0034] Optionally, the head of the locking element 500 is provided with an operating handle for easy rotation of the locking element 500. The locking element 500 is made of bolts.

[0035] Once the winding shaft 200 is fully wound, the operator simply needs to loosen the locking piece 500, remove the positioning sleeve 400, and then remove the outer side of the winding shaft 200 (the side furthest from the power element 800) to quickly unload the wound material from the other winding shaft 200. This process eliminates the need for laboriously scooping out loose materials from a deep basket, reducing labor intensity and making the operation simple and quick.

[0036] In one embodiment of the present invention, a curling device is described below. Figures 1 to 3 The winding shaft 200 has a small diameter end, and the small diameter ends of the two winding shafts 200 are aligned through a docking structure.

[0037] Optionally, the docking structure can employ a positioning stop structure, with an annular step (stop) designed at the small-diameter end of one crankshaft and a matching groove designed at the small-diameter end of the other crankshaft. When the small-diameter ends of the two crankshafts 200 are docked, the stop will naturally slide into the groove, automatically achieving radial (concentric) positioning, ensuring rotational dynamic balance, and avoiding vibration and noise during high-speed rotation.
