DETAILED DESCRIPTION

[0024] The following will be combined with the attached embodiment of the present invention Figure 1-8 , the technical solutions in the embodiments of the present invention are described in detail. Example 1

[0025] like Figure 1-8 As shown, the present invention is a quick-detachable printing device for processing thermal transfer paper, and its structure includes a main body 1, a control panel 2, a workbench 3, and an alarm light 4. The control panel 2 is fixedly installed on the side end of the main body 1, the workbench 3 is fixedly connected to the front end of the main body 1, and the alarm light 4 is fixedly installed on the top front end of the main body 1.

[0026] like Figure 2-3 As shown, the main body 1 includes a transfer paper installation structure 11, a guide roller 12, a printing module 13, a winding roller 14, a feeding roller 15, a printing module 16, and a box door 17. The transfer paper installation structure 11 is installed at the inner rear end of the main body 1. The height and angle of the transfer paper installation structure 11 can be adjusted. The top of the box door 17 is rotatably connected to the rear end face of the main body 1, and the box door 17 can be fixed by a clamping rod when it is flipped upward. After the transfer paper installation structure 11 is adjusted, it can extend from the opening after the box door 17 is opened to the outside of the main body 1. The staff can disassemble and install the paper roll outside, and the operation space is large and the difficulty is small.

[0027] There are a total of six guide rollers 12, all of which are installed inside the main body 1. The guide rollers 12 can guide the transfer paper and the printed fabric into the printing module 16, which is beneficial for the printing module 16 to heat and press down, so that the ink on the end surface of the transfer paper can evaporate and be printed on the end surface of the fabric to complete the printing process; the printing module 13 is fixedly installed inside the main body 1, the winding roller 14 is fixedly installed at the internal front end of the main body 1, the feeding roller 15 is fixedly installed at the top of the internal rear end of the main body 1, and the printing module 16 is arranged at the internal front end of the main body 1.

[0028] The operating principle of this part is: the transfer paper is installed on the transfer paper installation structure 11, guided to the printing module 16 through the guide roller 12, and the other end of the transfer paper is connected to the winding roller 14, so that the used transfer paper can be collected by the winding roller 14; and the woven fabric can be fixedly installed by the feeding roller 15, and the woven fabric is transported to the end face of the printing module 16 through the guide roller 12, and then heated and pressed down by the printing module 16, so that the ink on the end face of the transfer paper can evaporate and be dyed to the end face of the woven fabric to complete the printing process.

[0029] like Figure 4As shown, the transfer paper mounting structure 11 includes a mounting seat 111, an electric telescopic column 112, a supporting structure 113, a rotating shaft 114, and a driving motor 115. Two mounting seats 111 are provided, which are respectively mounted on the left and right sides of the interior of the main body 1. The electric telescopic column 112 is rotatably connected to the upper end surface of the mounting seat 111. The rotating shaft 114 is fixedly mounted on the bottom of the electric telescopic column 112. The rotating shaft 114 is engaged with the mounting seat 111. The driving motor 115 is fixedly mounted inside the main body 1. A mounting gear is sleeved on the motor shaft of the driving motor 115. The gear is meshed with a gear of the rotating shaft 114 located outside the mounting seat 111. By rotating the driving motor 115, the rotating shaft 114 can be driven to rotate, thereby realizing the angle adjustment.

[0030] The support structure 113 is detachably mounted on the top end surfaces of the two electric telescopic columns 112. The electric telescopic columns 112 can be automatically extended and retracted to achieve height adjustment, which is conducive to extending the support structure 113 to the outside of the main body 1 for operation, making it convenient for the staff to disassemble and replace the paper tube in the support structure 113.

[0031] like Figure 5 As shown, the support structure 113 includes a support seat a1, a slot a2, a limiting structure a3, and a support shaft a4. The support seat a1 is fixedly connected to the top end surface of the electric telescopic column 112. The end surface of the support seat a1 is concave to form a slot a2. The cross-section of the slot a2 is step-shaped, with a larger outer side and a smaller inner side.

[0032] The two ends of the support shaft a4 are respectively engaged in a slot a2, the diameter of the two ends of the support shaft a4 is larger than the middle part, the ends of the support shaft a4 and the support seat a1 remain stationary, and the middle part of the support shaft a4 can rotate normally.

[0033] There are two limiting structures a3, which are symmetrically installed on the upper and lower walls of the support seat a1. Under normal circumstances, the limiting structure a3 extends into the slot a2 and engages with the support shaft a4 to limit and fix the two ends of the support shaft a4. The supporting shaft a4 can be engaged through the limiting structure a3 so that the supporting shaft a4 can be fixedly installed in the slot a2.

[0034] like Figure 6 As shown, the limiting structure a3 includes a mounting frame a31, a fixing seat a32, a pressing block a33, a reset spring a34, a fixing shaft a35, a telescopic rod a36, and a clamping block a37. The mounting frame a31 is fixedly connected to the upper wall or lower wall end surface of the supporting seat a1, and the fixing seat a32 is fixedly installed on the outer end surface of the mounting frame a31. The mounting frame a31 is fixedly connected to the upper wall or lower wall of the support seat a1, the fixing seat a32 is fixedly connected to the outer end face of the mounting frame a31, the pressing block a33 passes through the fixing seat a32 and extends into the mounting frame a31, a reset spring a34 is sleeved on the middle part of the pressing block a33, and the two ends of the reset spring a34 are respectively fitted with the inner wall of the fixing seat a32 and the limit ring protruding out of the main body of the pressing block a33. When the pressing block a33 is pressed, the pressing block a33 moves inward for a distance, and the reset spring a34 is compressed. After being released, the reset spring a34 automatically resets, and the pressing block a33 also returns to its original state.

[0035] The fixed rotating shaft a35 is connected to the inside of the installation frame a31, and the telescopic rod a36 is rotatably connected to the fixed rotating shaft a35. One end of the telescopic rod a36 is rotatably connected to the end of the push block a33 located in the installation frame a31, and the other end of the telescopic rod a36 is rotatably connected to the end of the block a37 located in the installation frame a31. The block a37 is slidably connected to the inner end surface of the installation frame a31. When the push block a33 moves inward, the telescopic rod a36 is pushed to rotate around the fixed rotating shaft a35, and the other end of the telescopic rod a36 will also move inward, thereby driving the block a37 to slide inward for a distance, and guided by the end surface of the installation frame a31, it will not shake, but move in the horizontal direction, and the telescopic rod a36 will contract when the block a37 moves inward.

[0036] The clamping block a37 is engaged with the supporting shaft a4, and the engagement is released by pressing the pressing block a33, so that the supporting shaft a4 can be easily disassembled and installed.

[0037] All electrical structures of the device are connected to the control panel 2 and powered by an external power supply to achieve normal operation of each structure. At the same time, all operations can be performed by controlling the control panel 2 to control the switching of all electrical structures, reducing the difficulty and facilitating operation by staff.

[0038] The method of using the quick-detachable thermal transfer paper processing printing device of this embodiment is as follows: When the transfer paper is used up and the paper roll needs to be replaced, the box door 17 is opened and fixed by the clamping rod, the electric telescopic column 112 is flipped backward through the control panel 2, and then the electric telescopic column 112 is started, so that the electric telescopic column 112 drives the supporting structure 113 to extend to the outside of the main body 1. The supporting structure 113 can eventually extend to the outside of the main body 1, and the operating space is large, which is convenient for the staff to disassemble and replace the paper roll in the supporting structure 113.

[0039] When replacing, the pressing block a33 is pressed inwardly, and the return spring a34 is compressed. At this time, the telescopic rod a36 is pushed to rotate, and the block a37 rotatably connected to the other end of the telescopic rod a36 moves inward. At this time, the telescopic rod a36 shrinks a distance, and the block a37 moves inward to shrink, releasing the engagement with the support shaft a4. At this time, the support shaft a4 can be directly removed from the slot a2, which is convenient for installation and disassembly and installation of the paper tube.

[0040] After the paper roll is replaced, press the pressing block a33 again, insert the supporting shaft a4 into the card slot a2, and then release the pressing block a33. Then start the electric telescopic column 112 through the control panel 2 to restore it to its original state and enter the interior of the device body 1. Then flip the electric telescopic column 112 to make it perpendicular to the horizontal plane and reset it completely. Guide the transfer paper on the paper roll to the printing module 16 through the guide roller 12, and connect the other end of the transfer paper to the winding roller 14. Finally, close the box door 17. Example 2

[0041] This embodiment includes all the structures of the embodiment 1, and further deepens on the basis of the embodiment 1, such as Figure 7 As shown, the supporting shaft a4 includes a snap-fit ​​seat a41, a snap-fit ​​groove a42, an inner groove a43, and a paper tube mounting rod a44. The snap-fit ​​seat a41 is snapped into the inside of the snap-fit ​​groove a2 from the outside. The snap-fit ​​seat a41 is provided with snap-fit ​​grooves a42 on the upper and lower walls near the outside of the snap-fit ​​groove a2. There are two snap-fit ​​grooves a42, which match the snap-fit ​​block a37. The snap-fit ​​block a37 is snapped into the snap-fit ​​groove a42 to limit and fix the snap-fit ​​seat a41 to prevent it from rotating or shifting left and right, which would affect the normal transfer quality and effect.

[0042] The inner end surface of the engaging seat a41 is concave to form an inner groove a43, and the paper tube mounting rod a44 is sleeved and installed in the inner groove a43, and the paper tube mounting rod a44 can rotate in the inner groove a43 without affecting the work of the paper tube. The engaging seat a41 is a rectangular shape, and the engaging groove a2 matches the engaging seat a41, which is convenient for engaging and fixing, thereby improving the stability of the installation of the engaging seat a41.

[0043] like Figure 8 As shown, the paper tube mounting rod a44 includes a bearing s1 and a rod body s2. The bearing s1 is snap-fitted and installed in the inner groove a43. The rod body s2 is connected to the inner ring of the bearing s1. The bearing s1 is used to reduce the friction between the rod body s2 and the inner groove a43, so that the rod body s2 rotates smoothly.

[0044] A plurality of grooves s3 are evenly arranged on the surface of the rod body s2. The grooves s3 are in a wave shape. There are nine grooves s3 in total, which are evenly distributed around the end face of the rod body s2. The grooves s3 are used to increase the friction between the rod body s2 and the paper tube to prevent relative movement between the paper tube and the rod body s2, which affects the transfer quality and effect.

[0045] The method of using the quick-detachable thermal transfer paper processing printing device of this embodiment is as follows: When the paper tube needs to be replaced, only the pressing block a33 on one side is pressed, and the block a37 is disengaged from the engaging groove a42 of the engaging seat a41, and the engaging seat a41 can be taken out from the engaging groove a2, and the paper tube installation rod a44 is also separated from the engaging seat a41, which is convenient for installing the paper tube. At the same time, the released engaging seat also improves the stability of fixing the paper tube installation rod a44. During installation, one end of the paper tube installation rod a44 is inserted into the inner groove a43 of the engaging seat a41 that has not been removed, and the removed engaging seat a41 is reinstalled. Enter the card slot a2, and make its inner groove a43 also clamp one end of the paper tube mounting rod a44. When working, under the influence of the limiting structure a3, the clamping seat a41 will not rotate and stably clamp the paper tube mounting rod a44 to prevent it from shaking. At the same time, the groove s3 increases the friction between the transfer paper tube, so that the transfer paper tube and the rod body s2 remain stationary and rotate with the rod body s2, thereby improving the smoothness of the transfer paper output, making it easier to transfer the ink printed on the end surface of the transfer paper to the textile to complete the printing work.

[0046] The above embodiments are only for illustrating the technical idea of ​​the present invention, and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
