Description

Technical Field

[0001] This utility model relates to bed sheet production technology, specifically to a fabric winding device for bed sheet production. Background Technology

[0002] The fabric winding device for bed sheet production is a specialized piece of equipment used in bed sheet production lines to wind and store the cut, dyed, or finished fabric. Its core function is to neatly and tightly wind the continuously conveyed bed sheet fabric onto the winding roller through the rotation of the winding roller, forming a fabric roll that is easy to store, transport, and process. It is a key piece of equipment to ensure the continuity of the bed sheet production process and improve the efficiency of fabric handling.

[0003] In the current bed sheet production process, fabric winding mainly relies on winding rollers. The fabric is conveyed to the winding rollers by a guide mechanism, and the winding rollers rotate under the drive of the drive device, winding the fabric layer by layer. However, after a roll of fabric is wound up, the winding roller full of fabric must first be removed from the device, and then a new empty winding roller must be installed in the winding position and fixed before the next stage of winding can continue. Because the fabric rollers formed after the bed sheet fabric (especially heavy materials such as pure cotton and linen) is wound up are quite heavy, operators need to expend a lot of physical strength in the process of disassembling, moving and installing the winding rollers. This is not only cumbersome and time-consuming, but also may cause damage to the fabric or injury to personnel due to accidental slippage during the handling process. At the same time, repeated disassembly and installation operations will prolong equipment downtime, reduce production efficiency, and increase the labor intensity of operators, making it difficult to meet the needs of modern bed sheet production for efficient and convenient operation. Utility Model Content

[0004] The purpose of this invention is to provide a fabric winding device for bed sheet production, so as to solve the problems of time-consuming, labor-intensive, and high-labor intensity in the process of changing winding rollers in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fabric winding device for bed sheet production, comprising a winding frame, with guide brackets fixedly installed at the middle of both ends of the winding frame, a roller unloading groove at the top of one end of the guide bracket, a roller feeding groove at the bottom of one end of the guide bracket, and a plurality of winding rollers movably installed between the two guide brackets, with a roll of fabric wound around the outer surface of the winding rollers, and a positioning mechanism provided on one side of the winding frame for installing the winding rollers inside the winding frame;

[0006] The positioning mechanism includes a spline sleeve, which is symmetrically fixed to the front and rear ends of the take-up roller. The front and rear ends of the outer surface of the take-up frame are rotatably installed with support members at the junction of the unloading roller groove and the feeding roller groove. One end of the outer surface of the support member is threaded with a positioning screw, and one end of the positioning screw extends into the inside of the spline sleeve and is rotatably installed with a spline shaft.

[0007] The front end face of the winding frame is also provided with a transmission component for controlling the rotation of the winding roller between the two support members.

[0008] Furthermore, the transmission assembly includes a driven pulley, which is fixedly connected to a single support member near the front end face. A drive pulley is rotatably mounted on the front end face of the winding frame near the driven pulley. A connecting belt is fitted on the outer surface of both the driven pulley and the drive pulley. A drive unit is provided at the middle of one end of the drive pulley on the outer surface of the winding frame.

[0009] Furthermore, mounting holes are provided at both ends of the winding frame near the junction of the unloading roller groove and the feeding roller groove, and the support member is located inside the mounting hole, with the support member and the mounting hole being mutually compatible.

[0010] Furthermore, the outer diameter of the spline sleeve is smaller than the distance between the upper and lower ends of the inner walls of the unloading roller groove and the feeding roller groove, and the unloading roller groove and the feeding roller groove are both fitted into the spline sleeve.

[0011] Furthermore, a spline groove is formed in the middle of one end of the spline sleeve, and the edge of one end of the spline shaft extends into the spline groove, with the spline shaft and the spline groove engaging with each other.

[0012] Furthermore, a through hole is provided in the middle of one end of the driven pulley, the outer diameter of the positioning screw is smaller than the inner diameter of the through hole, and one end of the positioning screw extends to the outside of the driven pulley.

[0013] Compared with the prior art, the fabric winding device for bed sheet production provided by this utility model has the following beneficial effects:

[0014] 1. This utility model, through the cooperation of the unloading roller groove, the feeding roller groove and the spline sleeve, allows the finished fabric roller to slide out along the unloading roller groove and the new winding roller to slide in along the feeding roller groove, eliminating the need for manual handling; the spline shaft of the positioning mechanism and the spline sleeve quickly engage and are fixed with the positioning screw, simplifying the installation process and solving the problem of time-consuming and labor-intensive traditional disassembly and installation.

[0015] 2. The drive unit of the transmission component of this utility model drives the driven pulley to rotate through the active pulley and the connecting belt, thereby driving the support and the winding roller to rotate synchronously. The transmission is smooth and the power loss is small, ensuring that the fabric roll is wound neatly and tightly, and improving the winding quality.

[0016] 3. This utility model allows multiple take-up rollers to work alternately. When one take-up roller is winding, a new take-up roller can be installed in advance through the roller feed groove. After winding is completed, the switch can be made quickly, shortening the equipment downtime, adapting to the continuous production needs of bed sheet production, and improving the overall production efficiency.

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] Example 1:

[0027] This utility model provides a fabric winding device for bed sheet production, including a winding frame 1. Guide brackets 2 are fixedly installed at the middle of both ends of the winding frame 1. A roller unloading groove 3 is opened at the top of one end of the guide bracket 2, and a roller feeding groove 4 is opened at the bottom of one end of the guide bracket 2. A plurality of winding rollers 5 are movably installed between the two guide brackets 2. A roll of fabric 6 is wound around the outer surface of the winding rollers 5. A positioning mechanism is provided on one side of the winding frame 1 for installing the winding rollers 5 inside the winding frame 1.

[0028] The positioning mechanism includes a spline sleeve 7, which is symmetrically fixed to the front and rear ends of the take-up roller 5. The outer diameter of the spline sleeve 7 is smaller than the distance between the upper and lower ends of the inner walls of the unloading roller groove 3 and the feeding roller groove 4. The unloading roller groove 3 and the feeding roller groove 4 are both fitted with the spline sleeve 7. The front and rear ends of the outer surface of the take-up frame 1 are rotatably installed with support members 8 at the junction of the unloading roller groove 3 and the feeding roller groove 4. The front and rear ends of the take-up frame 1 are provided with through holes near the junction of the unloading roller groove 3 and the feeding roller groove 4. The support members 8 are located inside the mounting holes. The support members 8 and the mounting holes are mutually compatible. One end of the outer surface of the support member 8 is threaded with a positioning screw 9. One end of the positioning screw 9 extends into the spline sleeve 7 and is rotatably installed with a spline shaft 10. A spline groove is provided in the middle of one end of the spline sleeve 7. One end of the spline shaft 10 extends into the spline groove. The spline shaft 10 and the spline groove are mutually engaged.

[0029] The front end of the take-up frame 1 is also provided with a transmission component for controlling the rotation of the take-up roller 5 between the two support members 8.

[0030] Working principle: First, before winding, align the spline sleeves 7 at both ends of the new winding roller 5 with the feed roller groove 4 of the guide bracket 2, and push the winding roller 5 along the feed roller groove 4 into the space between the two guide brackets 2 until the spline sleeves 7 are aligned with the support 8.

[0031] Next, rotate the positioning screw 9, and push the positioning screw 9 inward along the threaded hole of the support member 8, pushing the spline shaft 10 into the spline groove of the spline sleeve 7 until the spline shaft 10 and the spline groove are fully engaged, and the take-up roller 5 is axially fixed and cannot move left or right; at this time, the support member 8 is rotatably connected to the take-up frame 1 through the mounting hole, providing rotational support for the take-up roller 5.

[0032] Then, the transmission assembly is started, and the drive unit 14 drives the active pulley 12 to rotate, which is transmitted to the driven pulley 11 through the connecting belt 13. The driven pulley 11 drives the support member 8 and the winding roller 5 to rotate synchronously. The bed sheet fabric is transported to the outer surface of the winding roller 5 and begins to wind to form a fabric roll 6.

[0033] Example 2:

[0034] This embodiment is basically the same as the previous embodiment, except that the transmission assembly includes a driven pulley 11, which is fixedly connected to a single support member 8 near the front end face. A drive pulley 12 is rotatably mounted on the front end face of the winding frame 1 near the driven pulley 11. A connecting belt 13 is sleeved on the outer surface of both the driven pulley 11 and the drive pulley 12. A drive unit 14 is provided at the middle of one end of the drive pulley 12 on the outer surface of the winding frame 1. The drive unit 14 is a drive motor.

[0035] A through hole is provided in the middle of one end of the driven pulley 11. The outer diameter of the positioning screw 9 is smaller than the inner diameter of the through hole, and one end of the positioning screw 9 extends to the outside of the driven pulley 11.

[0036] Working principle: First, turn off the drive unit 14 (drive motor), rotate the positioning screw 9 in the opposite direction to make the spline shaft 10 exit from the spline groove of the spline sleeve 7, and release the axial fixation of the take-up roller 5; at this time, the take-up roller 5 is only supported by the guide bracket 2 and can rotate freely.

[0037] Next, the take-up roller 5 is pushed to slide upward along the unloading roller groove 3 of the guide bracket 2, and the spline sleeve 7 slides out along the arc trajectory of the unloading roller groove 3. The fabric roll 6 naturally slides down with the take-up roller 5 onto the pre-placed transfer frame without the need for manual lifting.

[0038] Then, repeat the installation process of Embodiment 1, slide the new take-up roller 5 into the feed roller groove 4 and fix it, and start the drive unit 14 to continue the take-up operation.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
