Description

Technical Field

[0001] The utility model relates to the technical field of paper cup printing processing, in particular to a surface printing structure for paper cup processing. Background Art

[0002] The printed logo on the outside of the finished paper cup is produced by printing equipment on the raw paper tape of the cup body. During the printing process of the raw paper tape, in order to improve the printing and winding efficiency of the paper tape, the pigment needs to be quickly dried after the paper tape is printed to prevent the wet pigment from damaging other parts of the paper surface. This is quite common in daily life.

[0003] Existing technologies include a utility model with a publication number of CN220198825U, which discloses a paper cup printing machine. The patent includes a stand, a printing machine, a hot and cold water dispenser and a traction module, and also includes the following structures: a drying rack, the front and rear sides of the drying rack are respectively in contact with the rear side of the traction module and the discharge side of the printing machine; a guide pipe, the inner side of the guide pipe is fixedly provided with a water storage chamber, and the outer side of the guide pipe is movably sleeved with a guide sleeve. The hot and cold water dispenser flushes hot water into the guide pipe through the water outlet pipe and the water outlet diversion pipe according to the user's settings for heating. The guide sleeve rotates outside the guide pipe to complete the guiding operation of the paper tape, and heat transfer is formed between the guide pipe and the guide sleeve to realize the heating and drying treatment of the paper tape by the guide sleeve. There is no need to supply air to the paper tape during the overall drying process, avoiding the problem of impurities adhering to the surface of the undried pigment in the traditional hot air drying operation, and solving the problem of insufficient impurity prevention in the drying process of the existing paper cup printing machine.

[0004] In daily use, it is found that in the process of operating the paper cup printing processing equipment, the printing operation will be performed with the help of a printing roller. After long-term use, the printing roller will be worn and aged. At this time, the printing roller needs to be replaced and installed. Since the usual printing roller installation is mostly welded with bolts and nuts, the disassembly is relatively cumbersome, which leads to the problem of inconvenience in replacing and limiting the printing roller. Utility Model Content

The circular arc surfaces on both sides of the sliding column 405 are provided with connecting grooves 409. The inner wall of the connecting groove 409 is fixedly connected with a positioning rod 406. The circular arc surface of the positioning rod 406 is slidably connected to a limiting block 407. The cross-section of the limiting block 407 is " L" shape, the arc surface of the positioning rod 406 is covered with a spring 408, the two ends of the spring 408 are respectively fixedly connected to the limit block 407 and the bottom end of the inner wall of the connecting groove 409, the arc surface of the printing roller 3 is provided with an inlay hole 411 at the position corresponding to the limit block 407, the inner wall of the inlay hole 411 is snap-fitted with the short arm end surface of the limit block 407, the arc surface of the fixing ring 403 is provided with a plurality of auxiliary grooves 404, and the plurality of auxiliary grooves 404 are evenly distributed on the surface of the fixing ring 403, the sliding column 405 is fixedly connected to the end surface close to the printing roller 3 with a clamping block 410, the cross-section of the clamping block 410 is cross-shaped, the inner wall of the printing roller 3 is provided with a clamping groove 412, the inner wall of the clamping groove 412 is snap-fitted with the surface of the clamping block 410;

[0025] In the embodiments of the present invention, please refer to Figure 4 The limiting mechanism 5 includes a mounting frame 51. The cross-section of the mounting frame 51 is U-shaped. The bottom surfaces of both ends of the mounting frame 51 are fixedly connected to the side walls of the processing table 1. The inner wall of the mounting frame 51 is fixedly connected with a connecting rod 52. The arc surface of the connecting rod 52 slides through a number of moving rods 53. The bottom end of the moving rod 53 is fixedly connected to a fixing frame 55. The inner wall of the fixing frame 55 is rotatably connected to a pulley 56. The bottom end of the arc surface of the moving rod 53 is fixedly connected to a positioning ring 58. The arc surface of the moving rod 53 is covered with a tension spring 57.

[0026] The working principle of the surface printing structure for paper cup processing provided by the present invention is as follows: after the printing roller 3 is used for printing on the paperboard 2 for a long time, the printing roller 3 needs to be replaced and maintained. At this time, the installation mechanism 4 can be used to assist in the replacement operation. At this time, the replaced printing roller 3 is first lifted to a position close to the rotating shaft 401 by the driving frame 6, and then the sliding column 405 that moves along the slide groove 402 in the rotating shaft 401 is pulled so that the sliding column 405 is plugged into the inner wall of the printing roller 3. At this time, the position of the entire printing roller 3 will be temporarily fixed. Then, the fixing ring 403 on the surface of the rotating shaft 401 is rotated so that the fixing ring 403 squeezes the sliding column 405 until the surface of the sliding column 405 is completely fixed and overlapped with the inner wall of the printing roller 3. During this process, the limit blocks 407 that slide on the arc surface of the positioning rods 406 on both sides of the surface of the sliding column 405 need to be squeezed so that the short arm ends of the limit blocks 407 are clamped and fixed with the inlay holes 411 opened on the arc surface of the printing roller 3. At this time, the position of the entire printing roller 3 will be unable to move.

[0027] When the cardboard 2 on the surface of the processing table 1 is transported, the position of the cardboard 2 can be squeezed and limited with the help of the limiting mechanism 5. Through the connecting rod 52 fixed in the installation frame 51, the moving rod 53 that slides through the surface of the connecting rod 52 can be used to allow the pulley 56 at the bottom end of the moving rod 53 to squeeze and slide on the surface of the cardboard 2. At the same time, the extrusion force generated by the tension spring 57 sleeved on the surface of the moving rod 53 is used for extrusion protection, so that the cardboard 2 on the surface of the processing table 1 is squeezed by the pulley 56 during the movement, thereby preventing the cardboard 2 from tilting and position displacement.

[0028] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0029] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
