Description

Technical Field

[0001] This utility model relates to the field of PC endurance board manufacturing technology, specifically a PC endurance board shaftless winding device. Background Technology

[0002] Currently, polycarbonate (PC) solid sheets are widely used in construction, advertising, and transportation due to their impact resistance, high strength, ease of processing, plasticity, and flame-retardant bending properties. Depending on the application requirements, the thickness of the products varies. Products thicker than 5mm are often sheared and stacked for packaging, while products between 0.5-5mm require continuous winding for ease of use and transportation. Traditional spool winding machines are cumbersome to operate and prone to problems such as coiling, uneven stress, and misalignment when winding PC solid sheets. Therefore, developing a winding machine that is both easy to operate and adaptable to the high rigidity winding characteristics of PC solid sheets is of great significance for improving production efficiency and reducing manpower waste.

[0003] For example, the patent with announcement number CN222063566U discloses a pneumatic combined winding device for collecting edge material of electrolytic copper foil. By setting up an air expansion shaft and a drive mechanism, it realizes the automated winding of copper foil edge material. However, by setting up a winding air expansion shaft, the winding and unwinding process requires cumbersome inflation of the air expansion shaft, which increases the complexity of operation. In addition, for different specifications of materials, it is necessary to replace the air expansion shaft with one of different sizes, which further increases the operating cost.

[0004] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Summary of the Invention

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a shaftless winding device for PC endurance boards, which can improve production efficiency and reduce labor costs.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a PC endurance board shaftless winding device, including a base frame, a first support and a second support, a winding spindle is rotatably installed inside the first support and the second support, a winding disc is fixedly connected to one end of the two winding spindles, and a winding ring is fixedly provided on one side of the winding disc;

[0007] Guide blocks are fixedly connected to both sides of the second upright. Two symmetrically arranged adjusting screws are rotatably installed inside the base frame. A transmission nut is sleeved on the adjusting screw, and a connecting block is fixedly connected to the transmission nut. The transmission nut and the connecting block are slidably disposed inside the base frame. The top of the connecting block is fixedly connected to the bottom of the second upright.

[0008] Furthermore, a protective cover is fixedly installed on the top of the base frame, and a cavity is provided inside the protective cover. An adjusting shaft is rotatably installed inside the protective cover, and a handwheel is fixedly installed at one end of the adjusting shaft. The adjusting shaft and the adjusting screw are connected by a chain through a sprocket.

[0009] Furthermore, a torque motor is installed on the top of the base frame, and the output end of the torque motor is fixedly connected to a coaxially arranged transmission shaft through a coupling. One end of the transmission shaft is rotatably installed inside the protective cover, and both of the winding spindles are connected to the transmission shaft by a chain through a sprocket.

[0010] Furthermore, a clamping screw is rotatably mounted on each of the two winding discs, a clamping block is sleeved on the clamping screw, a clamping groove is opened on the winding disc, the clamping block is slidably connected inside the clamping groove, and a crank handle is fixedly provided at the top of the clamping screw.

[0011] Furthermore, two symmetrically arranged sliding guide rails are fixedly installed on the top of the base frame, and guide blocks are fixedly installed on both sides of the second upright, with the guide blocks slidably sleeved on the sliding guide rails.

[0012] The beneficial effects of this application are as follows: During winding, the second support is moved left and right by rotating the adjusting shaft until the distance between the two winding discs matches the width of the sheet. Then, the edge of the sheet is fixed to the winding ring by the clamping block. The torque motor is started, and the transmission shaft rotates and drives the winding main shaft and winding disc inside the first and second supports to rotate simultaneously through two chains.

[0019] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0020] like Figure 1-4 As shown, this application provides a shaftless winding device for PC endurance boards, including a base frame 1, a first support 3 and a second support 11. A winding spindle 13 is rotatably installed inside the first support 3 and the second support 11. A winding disc 5 is fixedly connected to one end of each of the two winding spindles 13. A winding ring 6 is fixedly provided on one side of the winding disc 5.

[0021] Guide blocks 17 are fixedly connected to both sides of the second support 11. Two symmetrically arranged adjusting screws 8 are rotatably installed inside the base frame 1. A transmission nut 10 is sleeved on the adjusting screw 8. A connecting block is fixedly connected to the transmission nut 10. The transmission nut 10 and the connecting block are slidably arranged inside the base frame 1. The top of the connecting block is fixedly connected to the bottom of the second support 11.

[0022] like Figure 1-4 As shown, a protective cover 14 is fixedly installed on the top of the base frame 1. The inside of the protective cover 14 is provided with a cavity. An adjusting shaft 16 is rotatably installed inside the protective cover 14. A handwheel is fixedly installed at one end of the adjusting shaft 16. The adjusting shaft 16 and the adjusting screw 8 are connected by a chain through a sprocket.

[0023] like Figure 1-4 As shown, a torque motor 2 is installed on the top of the base frame 1. The output end of the torque motor 2 is fixedly connected to a coaxially arranged transmission shaft 4 through a coupling. One end of the transmission shaft 4 is rotatably installed inside the protective cover 14. Both winding spindles 13 are connected to the transmission shaft 4 through sprockets and are fitted with chains. Both winding discs 5 are rotatably mounted with a clamping screw 7. A clamping block 12 is fitted on the clamping screw 7. A clamping groove is opened on the winding disc 5. The clamping block 12 is slidably connected inside the clamping groove. A crank is fixedly installed at the top of the clamping screw 7. Two symmetrically arranged sliding guide rails 9 are fixedly installed on the top of the base frame 1. Guide blocks 17 are fixedly installed on both sides of the second support 11. The guide blocks 17 are slidably fitted on the sliding guide rails 9.

[0024] The working principle of this utility model is as follows: When winding up the PC endurance board, first turn the handwheel to drive the adjusting shaft 16 to rotate. At this time, the adjusting screw 8 rotates synchronously under the drive of the sprocket and chain. The connecting block on the transmission nut 10 will drive the second support 11 to move left and right along the sliding guide rail 9. By driving the second support 11 to move left and right, the distance between the two winding discs 5 can be adjusted to be the same as the width of the PC endurance board to be wound.

[0025] Furthermore, after the spacing is adjusted, the starting end of the PC endurance board is introduced between the two winding discs 5, and its two sides are respectively attached to the winding rings 6 connected to the two winding discs 5. Then, the operator rotates the two clamping screws 7 in sequence. The clamping block 12 sleeved on the clamping screw 7 moves downward along the clamping groove. The clamping block 12 is slidably connected inside the clamping groove, and one side of the clamping block 12 passes through the clamping groove and is located above the winding ring 6. Therefore, the downward movement of the clamping block 12 will press the endurance board tightly and attach it to the winding ring 6, thereby achieving the fixing effect.

[0026] After the polycarbonate sheet is fixed, the torque motor 2 is started. The output end of the torque motor 2 drives the transmission shaft 4 to rotate together. Since the transmission shaft 4 passes through the first support 3 and the second support 11 and has through slots, and the transmission shaft 4 is connected to the winding spindle 13 rotating inside the first support 3 and the second support 11 by a chain sleeve through a sprocket, the rotation of the transmission shaft 4 will simultaneously drive the two winding spindles 13 and the winding disc 5 to rotate synchronously. Because the PC polycarbonate sheet is clamped on the synchronously rotating winding ring 6, and with its good rigidity, it can fit on the winding ring 6 and maintain a certain shape and stability, so that it can be smoothly wound up.

[0027] Finally, after winding is completed, the torque motor 2 is turned off, and the PC endurance board roll is packaged to complete the winding process. The operator moves the unloading rack 15 to the bottom of the endurance board roll, and rotates the clamping screws 7 on the two winding discs 5 again to make the clamping block 12 release the winding ring 6. Then, the operator rotates the handwheel to drive the second support 11 to move the endurance board roll, which will fall onto the unloading rack 15, thus completing the unloading.

[0028] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
