Description

Technical Field

[0001] This utility model relates to the field of water transfer printing paper production technology, and in particular to a water transfer printing paper coating head with an anti-leakage adhesive structure. Background Technology

[0002] Water transfer paper is the core intermediate material in the water transfer printing process, mainly used to achieve high-precision pattern adhesion on the surfaces of transparent or light-colored items such as crystal, glass, and ceramics. Its typical structure consists of a base paper layer, an adhesive layer, and a water-soluble adhesive layer. By soaking, the pattern layer detaches from the base paper and is transferred to the surface of the target object. After baking and curing, a wear-resistant and waterproof decorative layer is formed. During the production stage of water transfer paper, an adhesive layer needs to be evenly coated on the surface of the transfer paper using an adhesive applicator.

[0003] Existing glue applicators are inconvenient to close the dispensing chamber promptly after glue application, resulting in leakage of some water-soluble glue or solidification inside the dispensing head upon contact with air, causing blockage and affecting the next glue application. To address this, we propose an improved water transfer paper glue applicator with a leak-proof structure. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water transfer paper coating head with an anti-leakage adhesive structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a water transfer paper coating head with a leak-proof adhesive structure, comprising an adhesive inlet tube, wherein an adhesive inlet cavity and an installation cavity are respectively opened at both ends of the adhesive inlet tube, a plug is provided in the adhesive inlet cavity, a plug head is fixedly connected to the end of the plug near the installation cavity, a connecting rod is fixedly connected between the plug and the inner wall of the adhesive inlet cavity, a sealing block is slidably connected in the installation cavity, a conical cavity is opened in the middle of the sealing block, a guide cylinder is fixedly connected to the outer wall of the sealing block, a guide groove is opened in the adhesive inlet tube, the guide cylinder is movably sleeved in the guide groove, and an inner groove is opened at one end of the guide cylinder, a spring is fixedly connected between the inner groove and the inner wall of the guide groove, and an installation head is threadedly screwed to the end of the installation cavity away from the adhesive inlet cavity, and a glue nozzle is threadedly screwed to the outer wall of the casing of the installation head protruding from the adhesive inlet tube.

[0006] As a further description of the above technical solution: The connecting rods are provided in multiple ways, and the multiple connecting rods are evenly distributed on the outer wall of the plug.

[0007] With the above technical solution, the connecting rod is mainly used to fix the position of the plug in the glue inlet cavity.

[0008] As a further description of the above technical solution: Multiple guide cylinders are provided, and the multiple guide cylinders are evenly distributed on the outer wall of the sealing block facing the glue inlet cavity. The spring is movably sleeved in the guide groove.

[0009] The above technical solution allows the sealing block to be reset by pulling the guide cylinder with a spring.

[0010] As a further description of the above technical solution: A dynamic sealing ring is fixedly connected to the inner wall of the guide groove near the opening, and the guide cylinder passes through the dynamic sealing ring.

[0011] The above technical solution uses a dynamic sealing ring to seal the guide groove, preventing glue from entering the guide groove as the guide cylinder moves.

[0012] As a further description of the above technical solution: A partition is fixedly connected to the inner wall of the mounting cavity. The sealing block and the mounting head are respectively located at both ends of the partition, and a flow channel is provided in the middle of the partition.

[0013] Through the above technical solution, the baffle is used to limit the movement of the sealing block and the installation head, so as to prevent the sealing block from moving too far and causing the guide cylinder to be pulled out of the guide groove.

[0014] As a further description of the above technical solution: The plug is made of a conical structure, and the plug and the conical cavity are matched and arranged to match each other.

[0015] The above technical solution uses a plug fitted inside the conical cavity to prevent glue leakage from the glue inlet cavity.

[0016] As a further description of the above technical solution: The threads of the nozzle and the mounting head are screwed in the same direction, and the diameter of the dispensing channel in the nozzle is less than or equal to the diameter of the dispensing channel in the mounting head.

[0017] With the above technical solution, when assembling the mounting head, screw it into the mounting cavity in a clockwise direction, and then screw the nozzle onto the mounting head in the same clockwise direction. This unidirectional installation avoids loosening of the mounting head when installing the nozzle.

[0018] This utility model has the following beneficial effects: Compared with existing technologies, this water transfer paper applicator with a leak-proof adhesive structure, through the coordinated arrangement of a dynamic sealing ring, connecting rod, plug, plug, sealing block, conical cavity, guide cylinder, inner groove, guide slot, and spring structure, can use positive pressure to push the sealing block away from the plug during the adhesive application process, thereby opening the conical cavity channel for easy adhesive dispensing. When adhesive application stops, the positive pressure of the adhesive inlet disappears, and under the return force of the spring, the guide cylinder will pull the sealing block back to its original position, allowing the plug to re-enter the conical cavity to complete the blockage, thus preventing adhesive leakage due to untimely closure. At the same time, the threaded connection of the nozzle and the mounting head structure allows for easy disassembly of the nozzle and mounting head as needed, facilitating cleaning when the adhesive dispensing channel is blocked, making it practical.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-4This utility model provides a water transfer paper coating head with a leak-proof adhesive structure: it includes an adhesive inlet tube 1, with an adhesive inlet cavity 2 and an installation cavity 8 at both ends of the adhesive inlet tube 1. A plug 6 is provided in the adhesive inlet cavity 2, and a plug 7 is fixedly connected to the end of the plug 6 near the installation cavity 8. A connecting rod 5 is fixedly connected between the plug 6 and the inner wall of the adhesive inlet cavity 2. A sealing block 11 is slidably connected in the installation cavity 8. A conical cavity 12 is provided in the middle of the sealing block 11. A guide cylinder 13 is fixedly connected to the outer wall of the sealing block 11. A guide groove 1 is provided in the adhesive inlet tube 1. 5. The guide cylinder 13 is movably sleeved in the guide groove 15, and one end of the guide cylinder 13 is provided with an inner groove 14. A spring 16 is fixedly connected between the inner groove 14 and the inner wall of the guide groove 15. The spring 16 is in a pre-tight state in the initial state, which makes it easy to overcome the pressure generated by squeezing the glue when the sealing block 11 is pulled to reset, so that the sealing block 11 can be completely sleeved on the outer wall of the plug 7. The mounting cavity 8 is threaded with a mounting head 17 at the end away from the glue inlet cavity 2. The mounting head 17 protrudes from the outer wall of the glue inlet tube 1 and is threaded with a glue nozzle 3.

[0023] Multiple connecting rods 5 are provided, and the multiple connecting rods 5 are evenly distributed on the outer wall of the plug 6. The connecting rods 5 are mainly used to fix the position of the plug 6 in the glue inlet cavity 2.

[0024] Multiple guide cylinders 13 are provided, and the multiple guide cylinders 13 are evenly distributed on the outer wall of the sealing block 11 facing the glue inlet cavity 2. The spring 16 is movably sleeved in the guide groove 15. By pulling the guide cylinder 13 through the spring 16, the sealing block 11 can be reset.

[0025] A dynamic sealing ring 4 is fixedly connected to the inner wall of the guide groove 15 near the opening. The guide cylinder 13 is set through the dynamic sealing ring 4. The dynamic sealing ring 4 seals the guide groove 15 to prevent glue from moving into the guide groove 15 along with the guide cylinder 13.

[0026] A partition 9 is fixedly connected to the inner wall of the mounting cavity 8. The sealing block 11 and the mounting head 17 are respectively set at both ends of the partition 9, and a guide channel 10 is opened in the middle of the partition 9. The partition 9 is used to limit the sealing block 11 and the mounting head 17 to prevent the sealing block 11 from moving too far, which would cause the guide cylinder 13 to be pulled out of the guide groove 15.

[0027] The plug 7 is made of a conical structure, and the plug 7 and the conical cavity 12 are matched and set to prevent the glue in the glue inlet cavity 2 from leaking out by fitting the plug 7 into the conical cavity 12.

[0028] The threads of the nozzle 3 and the mounting head 17 are screwed in the same direction, and the diameter of the dispensing channel in the nozzle 3 is less than or equal to the diameter of the dispensing channel in the mounting head 17. When assembling the mounting head 17, screw it into the mounting cavity 8 in a clockwise direction, and then screw the nozzle 3 onto the mounting head 17 in the same clockwise direction. Installing in the same direction avoids loosening of the mounting head 17 when installing the nozzle 3.

[0029] Working principle: When the glue is dispensed, the positive pressure will push the sealing block 11 to move, causing it to detach from the plug 7, thus facilitating the continued flow of water-soluble glue through the conical cavity 12. When the glue is dispensed, the positive pressure decreases, and the spring 16 will pull the sealing block 11 back to its original position through the guide cylinder 13, so that it is re-attached to the plug 7 to complete the sealing of the conical cavity 12, thereby closing the glue inlet cavity 2 in time and preventing glue leakage. If the glue nozzle 3 becomes clogged later, the glue nozzle 3 can be directly rotated off the mounting head 17 for cleaning, which is convenient and time-saving.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
