Description

Technical Field

[0001] The utility model relates to the technical field of air cushion diverters, in particular to an air cushion diverter for a coating machine. Background Art

[0002] Coating machines are mainly used for the surface coating process of films, papers, etc. They coat the rolled substrate with a layer of glue, coating or ink with specific functions, and then cut it into sheets or roll it up after drying. As an important component of the coating machine, the air cushion diverter mainly realizes the steering and position adjustment of the working roller. During the coating process, if the direction or position of the working roller is incorrect, it may cause uneven coating, thus affecting production efficiency and product quality. The air cushion diverter transmits high-pressure gas to its interior, thereby adjusting the direction and position of the working roller, thereby solving this problem.

[0003] As is known to all, the structural principle of the air cushion diverter is relatively complex. It consists of multiple parts, including gas inlet, guide plate, air guide ring and air outlet, etc. Among them, the guide plate is the core component of the air cushion diverter, and the air flow inlet and outlet in the guide plate are used to control the steering of the air cushion diverter. During the operation of the coating machine, the air cushion diverter precisely controls the flow of high-pressure gas to enable the working roller to be smoothly and accurately steered and positioned. This not only improves the operating stability of the coating machine, but also effectively avoids the problem of uneven coating, thereby improving the quality and production efficiency of the product. It can be seen that it is particularly important to ensure the stability of air pressure in the air cushion diverter. However, when the existing air cushion diverter is in use, the air supply hose for conveying high-pressure gas is directly connected to the air inlet of the air cushion diverter, and there is a lack of buffer protection structure. When the air supply hose is pulled by external force, it is inevitable that the air supply hose and the air inlet will be loose, which will easily lead to air leakage and affect the normal operation of the air cushion diverter. In view of this, the present application proposes a coating machine air cushion diverter to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an air cushion diverter for a coating machine, which has a buffering and unloading function, effectively reducing the impact on the connection between the air supply hose and the air inlet nozzle when the air supply hose is pulled by external force, reducing the failure rate, improving the durability of the air cushion diverter, and ensuring the normal operation of the air cushion diverter body of the coating machine as much as possible.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a coater air cushion diverter, comprising a coater air cushion diverter body, an air inlet nozzle and a buffer mechanism mounted on the coater air cushion diverter body, the buffer mechanism comprising a support arm installed on the coater air cushion diverter body, the support arm being provided with two and arranged close to the air inlet nozzle, slide grooves being provided on the two support arms, the ends of the two slide grooves close to the air inlet nozzle are hinged with a first connecting arm, the ends of the two first connecting arms are hinged with a second connecting block, a blocking column is connected between the ends of the two first connecting arms, a slider is slidably embedded in the two slide grooves, the end of the second connecting block away from the first connecting arm is hinged to the slider, a spring is arranged between an end face of the slider away from the air inlet nozzle and an inner end wall of the slide groove, and a guide ring capable of allowing an air pipe to pass through is arranged between the ends of the two support arms away from the air inlet nozzle.

[0006] Preferably, the two support arms are arranged in parallel, and the two support arms are respectively arranged on both sides of the air inlet nozzle.

[0007] Preferably, a pair of connecting shafts are connected to the outer wall of the guide ring, and the pair of connecting shafts are respectively rotatably connected to one end of the two support arms away from the air inlet nozzle.

[0008] Preferably, balls are movably embedded on the inner circumferential surface of the guide ring, and the balls are arranged in a circle along the inner circumferential surface of the guide ring.

[0009] Preferably, a guide rod is inserted into the spring, one end of the guide rod is connected to the slider, and the other end of the guide rod movably passes through the end wall of the support arm.

[0010] Preferably, a limiting guide groove is provided on the side wall of the support arm along the length direction, the limiting guide groove is connected with the slide groove, a limiting guide block is movably embedded in the limiting guide groove, and a connecting bolt which is threadedly inserted into the sliding block is passed through the limiting guide block.

[0011] Preferably, a mounting ear plate is provided at one end of the support arm facing the coater air cushion diverter body, and a plurality of fixing bolts threadedly connected to the coater air cushion diverter body are passed through the mounting ear plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model uses the elastic support of the slider by the spring to maintain a triangular structure among the support arm, the first connecting arm and the second connecting block. When the air hose is pulled by an external force, the air hose between the guide ring and the air inlet nozzle will tend to be straight. At this time, the sliding of the slider in the slide groove and the elastic limiting support of the slider by the spring enable the blocking column to buffer and unload the air hose, effectively reducing the influence of external force pulling on the connection between the air hose and the air inlet nozzle, reducing the failure rate, and improving the durability of the air cushion diverter. In addition, the ball bearings arranged on the inner circular surface of the guide ring can reduce the wear of the air hose. The overall structure is simple and reasonable, and can ensure the normal operation of the air cushion diverter body of the coating machine as much as possible.

[0014] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

A spring 10 is provided, and a guide ring 11 capable of allowing an air pipe to pass through is provided between the ends of the two support arms 4 away from the air inlet nozzle 2. Through this structural mode, the air supply hose passes through the guide ring 11 and bypasses the blocking column 9 away from the side of the support arm 4 and is connected with the air inlet nozzle 2. The spring 10 elastically supports the slider 7 so that a triangular structure is maintained between the support arm 4, the first connecting arm 6 and the second connecting block 8, so that the blocking column 9 can provide elastic support and protection for the input hose. When the air supply hose is pulled by external force, the sliding of the slider 7 in the slide groove 5 and the elastic limiting support of the slider 7 by the spring 10 are utilized, so that the blocking column 9 can buffer and unload the air supply hose, effectively reducing the influence of external force pulling on the connection between the air supply hose and the air inlet nozzle 2, thereby reducing the failure rate and improving the durability of the air cushion steering gear.

[0023] In this embodiment, a mounting ear plate 12 is provided at one end of the support arm 4 facing the coater air cushion diverter body 1, and a plurality of fixing bolts 13 threadedly connected to the coater air cushion diverter body 1 are passed through the mounting ear plate 12 to facilitate the assembly of the support arm 4. Specifically, the two support arms 4 are arranged in parallel, and the two support arms 4 are respectively arranged on both sides of the air inlet nozzle 2, so that the guide ring 11 is aligned with the air inlet nozzle 2, so that the blocking column 9 can better provide elastic buffering protection for the input hose.

[0024] As a preferred implementation of this embodiment, a pair of connecting shafts 18 are connected to the outer wall of the guide ring 11, and the pair of connecting shafts 18 are respectively rotatably connected to the ends of the two support arms 4 away from the air inlet nozzle 2, so that the guide ring 11 can be rotated to adjust the direction according to the arrangement of the gas delivery hose. Balls 19 are movably embedded on the inner surface of the guide ring 11, and the balls 19 are arranged in a circle along the inner surface of the guide ring 11 to reduce the wear between the input hose and the guide ring 11.

[0025] Furthermore, a guide rod 17 is inserted into the spring 10, one end of which is connected to the slider 7, and the other end of which movably penetrates the end wall of the support arm 4, and is used to limit and guide the slider 7 and the spring 10. A limit guide groove 14 is provided on the side wall of the support arm 4 along the length direction, and the limit guide groove 14 is connected to the slide groove 5. A limit guide block 15 is movably embedded in the limit guide groove 14, and a connecting bolt 16 threadedly plugged with the slider 7 is inserted into the limit guide block 15, and is used to further limit and guide the slider 7 to prevent the slider 7 from slipping out of the slide groove 5, and after the connecting bolt 16 is removed, the slider 7 can be detached from the slide groove 5 for easy assembly.

[0026] When in use, the air hose is passed through the guide ring 11, and then bypasses the blocking column 9 and is connected to the air inlet nozzle 2 on the side away from the support arm 4, so as to deliver high-pressure gas to the coater air cushion diverter body 1, thereby providing air cushion diverting and position adjustment functions for the coating roller. The spring 10 elastically supports the slider 7 to maintain a triangular structure between the support arm 4, the first connecting arm 6 and the second connecting block 8. When the air hose is pulled by external force, the air hose between the guide ring 11 and the air inlet nozzle 2 will tend to be straight. At this time, the sliding of the slider 7 in the slide groove 5 and the elastic limiting support of the slider 7 by the spring 10 are used to enable the blocking column 9 to buffer and unload the air hose, thereby effectively reducing the influence of external force pulling on the connection between the air hose and the air inlet nozzle 2, reducing the failure rate, and improving the durability of the air cushion diverter.
