Description

Technical Field

[0001] The utility model relates to the technical field of heat transfer equipment, and particularly relates to a rewinding device for a heat transfer printing equipment. Background Technique

[0002] Heat transfer is a new printing process. First, the required pattern is printed on the transfer paper, and then the transfer paper and the fabric are printed at high temperature and high pressure through a transfer machine, so that the pattern ink on the transfer paper is printed on the fabric by means of high-temperature sublimation. Thus, the pattern can be firmly attached to the fabric. After the printing work is completed, a rewinding device will be set at the end of the equipment to wind up the finished product for subsequent packaging and transportation.

[0003] In the utility model patent with the publication number CNU, a rewinding device for environment-friendly heat transfer printing is proposed, which includes a bottom plate. A turntable support and a motor support are fixedly arranged on the bottom plate. A connecting shaft parallel to the bottom plate is rotatably arranged on the turntable support. A turntable is rotatably arranged on the connecting shaft. Two symmetrically arranged rotating shafts are rotatably arranged on the turntable. The two rotating shafts and the connecting shaft are parallel to each other. A motor is arranged on the motor support. The output end of the motor is fixedly connected to the connecting shaft. The connecting shaft and the rotating shaft are connected through a gear transmission mechanism. A rewinding shaft for winding the fabric is slidably sleeved outside the rotating shaft. The rewinding shaft is adaptively engaged with the rotating shaft. A limiting member for limiting the turntable is arranged on the bottom plate.

[0004] When the above case is used, the two rewinding shafts are driven to rotate by the turntable so that the rewinding shafts can work alternately, and the turntable is limited by the slidably arranged extension rod. However, when the fabric is wound around the rewinding shaft, there is no structure to fix the fabric, resulting in manual holding of the fabric. After the fabric is wound around the outside of the rewinding shaft for several circles, the device can work normally, which not only increases the working difficulty, but also easily harms the hands of the personnel. Moreover, every time the turntable is rotated, it is necessary to squat down and pull the extension rod to complete the fixation and unlocking of the turntable, reducing the working efficiency.

[0005] Therefore, the utility model provides a rewinding device for a heat transfer printing equipment to meet the requirements. Content of the Utility Model

[0006] The utility model provides a rewinding device for a heat transfer printing equipment, which can solve the problem that in the prior art during actual work, there is no structure to fix the fabric, resulting in manual holding of the fabric. After the fabric is wound around the outside of the rewinding shaft for several circles, the device can work normally, which not only increases the working difficulty, but also easily harms the hands of the personnel. Moreover, every time the turntable is rotated, it is necessary to squat down and pull the extension rod to complete the fixation and unlocking of the turntable, reducing the working efficiency.

[0007] To solve the above technical problems, the utility model provides the following technical solutions:

[0008] A winding device for a heat transfer printing device, comprising a main body, a limiting frame fixedly connected to the top of the main body, a rotating seat rotatably connected to the outside of the limiting frame, rotating rods rotatably connected to both ends inside the rotating seat, a fixing seat fixedly connected to one side of the rotating seat and adapted to the rotating rod, a clamping block slidably connected inside the fixing seat, and a pushing plate slidably connected to the outside of the rotating rod; a sliding component for adjusting the position of the clamping block, the sliding component being connected to the clamping block; a positioning component for limiting the position of the rotating seat, the positioning component being connected to the main body.

[0015] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0016] In the above solution, by setting the sliding component, the device can adjust the position of the clamping block through the elastic setting of the sliding elastic piece, and clamp the fabric on the outer side of the rotating rod through the clamping block, eliminating the need for manual fixation of the fabric. This not only reduces the working difficulty but also avoids the occurrence of injuries to the staff's hands when the fabric is entangled. Moreover, through the cooperation of the clamping block and the clamping groove, the stability of the clamping block is enhanced, and through the strengthening elastic piece, the strength and supporting force of the sliding elastic piece are increased, enhancing the performance of the sliding component.

[0026] The following will describe in detail the winding device of a heat transfer printing device provided by the present utility model in conjunction with the accompanying drawings and specific embodiments; at the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods.

[0027] As Figures 1 to 5 shown, an embodiment of the present utility model provides a winding device for a heat transfer printing device, including a main body 1. A limiting frame 2 is fixedly connected to the top of the main body 1. A rotating seat 4 is rotatably connected to the outside of the limiting frame 2. Both ends inside the rotating seat 4 are rotatably connected to a rotating rod 5. A fixing seat 6 adapted to the rotating rod 5 is fixedly connected to one side of the rotating seat 4. A clamping block 7 is slidably connected inside the fixing seat 6, and a sliding assembly 8. The sliding assembly 8 is used to adjust the position of the clamping block 7. The sliding assembly 8 is connected to the clamping block 7. The number of the sliding assemblies 8 is four, and they are distributed in pairs on the outside of the clamping block 7. The sliding assembly 8 includes a fixing piece 801 fixedly connected to the outside of the clamping block 7. A sliding elastic piece 802 is fixedly connected to the outside of the fixing piece 801. Both ends inside the sliding elastic piece 802 are fixedly connected to a reinforcing elastic piece 803. A clamping block 804 is fixedly connected to the middle of the outside of the sliding elastic piece 802. An avoidance groove 805 adapted to the sliding elastic piece 802 is opened on the outside of the fixing piece 801. The side of the reinforcing elastic piece 803 away from the sliding elastic piece 802 is fixedly connected to the fixing piece 801. A sliding groove adapted to the sliding assembly 8 is opened inside the fixing seat 6. Card slots adapted to the clamping block 804 are opened at both ends of the sliding groove. A motor 12 is fixed to the side of the rotating seat 4 away from the fixing seat 6. The motor 12 is fixedly connected to one of the rotating rods 5.

[0028] Place the fabric to be wound on the outside of the upper rotating rod 5. Push the clamping block 7 close to the fabric. The card slot and the clamping block 804 cause the sliding elastic piece 802 to deform into the avoidance groove 805. The clamping block 804 disengages from the card slot and moves until it slides to the card slot at the other end. The sliding elastic piece 802 is no longer stressed and rebounds, pushing the clamping block 804 into the card slot to complete unlocking. Clamp the fabric on the outside of the rotating rod 5 through the clamping block 7. Start the motor 12 to drive the rotating rod 5 to rotate for winding.

[0029] The sliding elastic piece 802 is made of elastic metal. Only by slightly applying force to the clamping block 7 can the sliding elastic piece 802 be pushed to deform inward, causing the clamping block 804 to disengage from the card slot in the fixed seat 6. With the assistance of the reinforcing elastic piece 803, the clamping block 7 can smoothly move along the sliding slot to the desired position. The reinforcing elastic piece 803 not only enhances the overall strength and supporting force of the sliding elastic piece 802 but also ensures the stability and accuracy of the clamping block 7 during movement, effectively preventing deviation caused by vibration or external interference. After the clamping block 7 clamps the fabric, the sliding elastic piece 802 quickly rebounds under the action of the elastic restoring force, and the clamping block 804 automatically snaps into a new card slot, realizing the stable locking of the clamping block 7 without the need for continuous manual force application, greatly simplifying the operation steps, reducing the work difficulty, and effectively avoiding injury accidents caused by fabric entanglement or out-of-control situations.

[0030] As Figures 1 to 6 shown, a push plate 11 is slidably connected to the outer side of the rotating rod 5. There is a positioning component 9 which is used to limit the position of the rotating seat 4. The positioning component 9 is connected to the main body 1 and is located directly below the rotating seat 4. The positioning component 9 includes a mounting piece 901 fixedly connected to the main body 1. A positioning elastic piece 902 is fixedly connected to the top of the mounting piece 901. A supporting elastic piece 903 is fixedly connected to the inner side of the positioning elastic piece 902. The top of the positioning elastic piece 902 is arc-shaped. Positioning slots 10 adapted to the positioning elastic piece 902 are provided at both the top and bottom of the rotating seat 4. A rotating wheel 13 is fixedly connected to the outer side of the rotating rod 5, and the rotating wheel 13 is located on the side of the rotating seat 4 close to the motor 12. A transmission belt 14 is rotatably connected to the inner side of one of the rotating wheels 13, and the two rotating wheels 13 are connected by the transmission belt 14 for transmission. A cutting structure 3 is fixedly connected to one side of the top of the main body 1 where the limiting frame 2 is located. A sliding seat is slidably connected to the top of the cutting structure 3, and a cutting knife is slidably connected to one side of the sliding seat.

[0031] When the upper rotating rod 5 finishes winding, turn off the motor 12 and rotate the rotating seat 4. The positioning slot 10 squeezes the positioning elastic piece 902, causing the positioning elastic piece 902 to deform inward and then disengage from the positioning slot 10. Rotate the rotating seat 4 by 180 degrees. The positioning elastic piece 902 is under the pressure of the rotating seat 4, deforms and snaps into another positioning slot 10, thus preventing the rotating seat 4 from shifting during rotation. Push the sliding seat to make it close to the fabric, and then push the cutting knife to cut the fabric. Then fix the fabric on the outer side of the empty rotating rod 5. Start the motor 12. The motor 12 drives one of the rotating rods 5 and the connected rotating wheel 13 to rotate. Through the transmission of the transmission belt 14, the other rotating wheel 13 and the corresponding rotating rod 5 will also rotate synchronously for winding work, and then push out the fabric on the outer side of the lower rotating rod 5 through the push plate 11.

[0032] The clamping elastic piece 902 is an elastic metal structure. When the adapter 4 moves to a specific position, its bottom or top will naturally press against the top end of the clamping elastic piece 902. The top of the clamping elastic piece 902 is arc-shaped, which not only helps to reduce the frictional resistance when contacting the adapter 4, but also can elastically deform when being pressed, and then smoothly slide into the clamping groove 10 on the adapter 4, realizing the automatic locking of the adapter 4 and ensuring its stability and reliability during the working process. The existence of the supporting elastic piece 903 not only provides additional supporting force for the clamping elastic piece 902 to prevent it from being excessively deformed or damaged when being pressed.

[0033] The working principle provided by the present utility model: Place the fabric to be wound on the outside of the upper rotating rod 5, push the clamping block 7 close to the fabric, the clamping groove and the clamping block 804, so that the sliding elastic piece 802 deforms into the avoidance groove 805, the clamping block 804 disengages from the clamping groove and moves until it slides to the clamping groove at the other end. The sliding elastic piece 802 is no longer stressed and rebounds, pushing the clamping block 804 into the clamping groove to complete the unlocking. Clamp the fabric on the outside of the rotating rod 5 through the clamping block 7, start the motor 12 to drive the rotating rod 5 to rotate for winding. When the upper rotating rod 5 finishes winding, turn off the motor 12, rotate the adapter 4, the clamping groove 10 presses the clamping elastic piece 902, causing the clamping elastic piece 902 to deform inward and then disengage from the clamping groove 10. Rotate the adapter 4 by 180 degrees, the clamping elastic piece 902 is stressed by the adapter 4, will deform and snap into another clamping groove 10, thereby preventing the adapter 4 from shifting during rotation. Push the sliding seat to make it close to the fabric, and then push the cutting knife to cut the fabric. Then fix the fabric on the outside of the empty rotating rod 5, start the motor 12, the motor 12 drives one of the rotating rods 5 and the connected rotating wheel 13 to rotate. Through the transmission of the transmission belt 14, the other rotating wheel 13 and the corresponding rotating rod 5 will also rotate synchronously for winding work, and then push out the fabric on the outside of the lower rotating rod 5 through the push plate 11.

[0035] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
