Description

Technical Field

[0001] This utility model relates to the field of glass product coating technology, specifically to a plasma spray gun assembly for a bottle-shaped glass product coating device. Background Technology

[0002] The plasma spray gun in the coating equipment for bottle-shaped glass products is the core component of the coating process. It generates a high-temperature and high-speed plasma jet by ionizing the working gas through a high-frequency electric arc between electrodes. This jet melts the coating material and sprays it onto the glass surface at high speed to form a uniform and dense coating. To ensure the stability of glass products during processing, the industry commonly uses support frames to fix the bottle-shaped glass products to be processed. This fixing method can effectively prevent the bottle-shaped glass products from shifting or tipping over in subsequent processing stages, providing a basic guarantee for the smooth progress of coating operations. Therefore, it has been widely used in various bottle-shaped glass product coating production lines. However, in the actual coating process, when it is necessary to treat the mouth of bottle-shaped glass products with circumferential plasma spray gun, a difficult technical problem is encountered. When the staff holds the plasma spray gun and sprays around the mouth of the bottle, the lack of effective fulcrum support makes it difficult for the spray gun to form a stable trajectory during the entire circumferential movement. Specifically, when the staff moves the spray gun, even slight hand tremors and slight changes in force will directly affect the movement state of the spray gun, resulting in inconsistent distances between the spray gun and the mouth of the bottle at different positions in the circumferential movement. This inconsistency in circumferential movement distance will directly and seriously affect the coating quality. Therefore, a plasma spray gun assembly for a coating device for bottle-shaped glass products is proposed to address the above problems. Utility Model Content

[0016] Please see Figures 1-6 This utility model provides a technical solution: A plasma spray gun assembly for coating bottle-shaped glass products includes a spray gun body 1. A connecting frame 2 is fixed to the bottom end of the spray gun body 1, and the connecting frame 2 is located at the center of the bottom end of the spray gun body 1. The spray gun body 1 and an adjustment mechanism 3 are parallel to each other. An adjustment mechanism 3 is fixed to one side of the connecting frame 2, and a clamping mechanism 4 is installed on one side of the adjustment mechanism 3. A buffer mechanism 5 is installed between the clamping mechanism 4 and the adjustment mechanism 3. The adjustment mechanism 3 includes a connecting seat 31, and damping shafts 32 are rotatably connected to both sides inside the connecting seat 31. An adjustment seat 33 is fixed to the top of the damping shaft 32, and a gear 34 is fixed to the top of the adjustment seat 33. The lower part of the connecting seat 31... A pneumatic motor 35 is fixed to the surface; the clamping mechanism 4 includes two connecting arms 41, which are symmetrically distributed on the left and right. The connecting arms 41 have an arc-shaped structure. One end of the connecting arm 41 is rotatably set inside the adjusting seat 33. A limit plug 42 is threaded to one side inside the connecting arm 41. A limit head 43 is fixed to the front end of the limit plug 42. A connecting rib 44 is fixed to the front end of the limit plug 42. Deformation grooves 45 are opened in the corner areas of the connecting rib 44 and the inner side of the connecting arm 41. A positioning plate 46 is fixed to the front end of the connecting rib 44. The spraying end of the spray gun body 1 is located above the positioning plate 46. A ventilation groove 47 is opened on the inner side of the positioning plate 46.

[0017] As a further implementation of this solution, the buffer mechanism 5 includes a buffer column 51 and a buffer seat 52. The buffer column 51 is fixedly installed on one side inside the connecting arm 41, and the buffer seat 52 is fixedly installed at the front end of the adjusting seat 33. A tension spring 53 is installed between the buffer seat 52 and the buffer column 51. With this arrangement, the closing impact force is absorbed by the elastic deformation of the tension spring 53, avoiding rigid collisions that could damage the connection between the glass product and the connecting arm 41. As a further implementation of this solution, the pneumatic motor 35 is located below one of the damping shafts 32. The transmission shaft of the pneumatic motor 35 is fixedly connected to the bottom end of the damping shaft 32, and the two gears 34 are meshed. This transmission method ensures the consistency of movement of the adjusting seat 33 and avoids the positioning plate 46 from shifting due to unilateral adjustment. As a further implementation of this solution, the two positioning plates 46 are symmetrically distributed from left to right. Each positioning plate 46 has multiple ventilation slots 47 on its inner side, and the multiple ventilation slots 47 are arranged in an arc shape. Both ends of the positioning plates 46 are arc-shaped structures. This symmetrically distributed positioning plates 46 can apply clamping force evenly and prevent the glass from shifting under force. The ventilation slots 47 can enhance the air circulation at the contact points and prevent local overheating from affecting the coating quality. As a further implementation of this solution, the axis of the limiting screw plug 42 and the axis of the limiting head 43 are located on the same central axis. The limiting head 43 has a spherical structure and is located between the connecting arm 41 and the connecting rib 44. In this solution, the limiting screw plug 42 and the limiting head 43 are designed to be coaxial to ensure that the contact position of the limiting head 43 with the connecting rib 44 is accurate. When circumferential movement is required, the limiting screw plug 42 is loosened and the limiting head 43 moves away from the connecting rib 44. The elastic deformation of the deformation groove 45 between the connecting rib 44 and the connecting arm 41 is used for buffering.

[0018] Work process: In the natural state, the two adjusting seats 33 are in the open state, the connecting arm 41 of the clamping mechanism 4 opens with the adjusting seats 33, the positioning plate 46 is in the clamping position, the limiting screw plug 42 is in the tightened state, and the limiting head 43 abuts against the connecting rib 44. In use, the pneumatic motor 35 is started, and its drive shaft drives the damping shaft 32 connected to it to rotate synchronously. The damping shaft 32 drives the gear 34 at the top to rotate. Since the two gears 34 are meshed, the other gear 34 rotates accordingly, which in turn drives the corresponding damping shaft 32 and adjusting seat 33 to move, causing the two adjusting seats 33 to perform a closing motion. When the adjusting seats 33 move, they drive the connecting arm 41 of the clamping mechanism 4 connected to them to move synchronously. The opening adjusting seat 33 drives the connecting arm 41 to move. The connecting arm 41, through the connecting rib 44, drives the positioning plate 46 to move to the corresponding position of the bottle-shaped glass product. The switch controls the drive shaft of the pneumatic motor 35 to reverse, causing the adjusting seat 33 to close. This drives the connecting arm 41, connecting rib 44, and positioning plate 46 to approach and clamp the bottle-shaped glass product. During the clamping process, the closing impact force is transmitted to the connecting arm 41 through the positioning plate 46 and connecting rib 44. Since the connecting arm 41 is rotatably connected to the adjusting seat 33, the breakage caused by the rigid connection is avoided. At the same time, the tension spring 53 of the buffer mechanism 5 is stretched between the buffer column 51 and the buffer seat 52, providing buffer for the connection between the connecting arm 41 and the adjusting seat 33, and preventing the closing impact force from damaging the connection between the glass product and the clamping mechanism 4. When performing circumferential spray coating, loosen the limiting screw plug 42 so that the limiting head 43 does not come into contact with the connecting rib 44. The operator holds the spray gun body 1 and performs circumferential spraying around the mouth of the bottle-shaped glass product being clamped. The vibration generated during the movement is buffered by the elastic deformation of the deformation groove 45 between the connecting rib 44 and the connecting arm 41, providing support for the stable movement of the spray gun body 1. The ventilation groove 47 inside the positioning plate 46 improves the airflow during the rotation process and reduces the heat generated by friction. After the coating operation is completed, stop spraying from the spray gun body 1, start the pneumatic motor 35 to open the adjusting seat 33, and drive the clamping mechanism 4 to release the bottle-shaped glass product.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
