Description
Technical Field
[0001] The utility model relates to the technical field of spraying brackets, in particular to a bracket for spraying plastic products. Background Art
[0002] Plastic products are a general term for household and industrial products made primarily from plastic. This includes products made using all processes, including injection molding and blister molding. During the production process, plastic products are often coated with a layer of paint using spray equipment to enhance their aesthetics.
[0003] When spraying existing plastic products, the product needs to be placed on a bracket and then fixed, and then sprayed through the spray equipment. However, when the existing spray bracket is clamped, the distance between the bracket and the plastic product is small, causing the bracket to block the spray gun's spraying, resulting in poor performance. In addition, when using, because the bracket cannot be adjusted in angle, when spraying different surfaces of the plastic product, the worker needs to remove the plastic product from the bracket and then change the orientation of the clamp before spraying the other surface of the plastic product, which is inconvenient. To this end, we propose a bracket for spraying plastic products. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0025] Reference Figures 1-4 A bracket for spraying plastic products includes a mounting base 1, and two strip mounting plates 14 are symmetrically installed on the top of the mounting base 1. The staff can fix the mounting base 1 on the workbench of the spraying equipment.
[0026] like Figure 1 and Figure 2 As shown, a first fixed seat 12 is installed on one side of the top of each strip mounting plate 14, and a bidirectional screw rod 3 is rotatably connected between the two first fixed seats 12. Both end sides of the bidirectional screw rod 3 are covered with support frames 4, and the support frames 4 are threadedly matched with the bidirectional screw rod 3. During actual use, the staff rotates the bidirectional screw rod 3 to control the synchronous relative movement of the two support frames 4, and the distance between the two support frames 4 can be adjusted as needed.
[0027] like Figure 1 and Figure 2As shown, the top of each support frame 4 extends to the top of the bidirectional screw rod 3, and a strip connecting rod 5 is vertically installed on one side of each support frame 4. The adjacent surfaces of the two strip connecting rods 5 are rotatably connected to the rotating shaft 6, and the adjacent ends of the two rotating shafts 6 are fixedly installed with a strip fixing plate 7. The adjacent ends of the two strip fixing plates 7 are vertically installed with a push rod 8. The end of each push rod 8 is installed with a clamping block 9. In actual use, the staff can bring one side of the sprayed plastic product into contact with the clamping block 9 on one side, and then the staff rotates the bidirectional screw rod 3 to make the two support frames 4 move relative to each other, and the support frame 4 drives the clamping block 9 to move, so that the plastic product can be clamped and fixed by the clamping block 9, and under the action of the push rod 8, there will be a distance between the plastic product and the support frame 4, so that the support frame 4 will not cause any hindrance during spraying.
[0028] It should be noted that the distance between the top of the two strip fixing plates 7 and the rotating shaft 6 is smaller than the distance between the bottom of the strip fixing plates 7 and the rotating shaft 6. In this way, when the plastic product is clamped and fixed, the strip fixing plate 7 away from the sliding sleeve 10 will move to a vertical position under the action of gravity, without the need for manual adjustment by the staff.
[0029] like Figure 3 As shown, a retaining ring 16 is installed at the other end of the sliding sleeve 10, and a connecting ring 18 is installed on the side of the strip connecting rod 5 close to the retaining ring 16. The adjacent surfaces of the retaining ring 16 and the connecting ring 18 are both installed with gear rings 17, and the two gear rings 17 are engaged with each other. In actual use, the rotating shaft 6 can be fixed by the engagement of the two gear rings 17, so that when the plastic products are sprayed, the strip fixing plate 7 will not be rotated by the impact force generated by the spraying.
[0030] like Figure 3 As shown, one end of one of the rotating shafts 6 is covered with a sliding sleeve 10, and a first support ring 11 is installed at one end of the rotating shaft 6. A second support ring 20 is extended from the outer surface of one end of the sliding sleeve 10, and a spring 19 is provided between the first support ring 11 and the second support ring 20. The spring 19 is covered on the rotating shaft 6, and the two ends of the spring 19 are against the adjacent surfaces of the first support ring 11 and the second support ring 20. During actual use, the elasticity of the spring 19 will push the sliding sleeve 10 to move, so that the gear ring 17 at one end of the sliding sleeve 10 is engaged with the gear ring 17 fixed on the side of the strip connecting rod 5, thereby fixing the rotating shaft 6. In this way, the strip fixing plate 7 will not rotate during spraying.
[0031] like Figure 4As shown, at least one guide groove 21 is provided on the side of one of the rotating shafts 6, and a guide block 22 is installed on one end of the inner surface of the sliding sleeve 10. One end of the guide block 22 extends into the guide groove 21. With the cooperation of the guide block 22 and the guide groove 21, the sliding sleeve 10 and the rotating shaft 6 can be limited to prevent the sliding sleeve 10 from rotating relative to the rotating shaft 6 during use.
[0032] It should be noted that the outer surface of the guide block 22 is clearance-matched with the inner surface of the guide groove 21 . In actual use, the guide block 22 will not shake in the guide groove 21 , thus ensuring a stable connection between the sliding sleeve 10 and the rotating shaft 6 .
[0033] Specifically, when the present invention is in use, the staff fixes the mounting base 1 on the workbench of the spraying equipment, and then contacts one side of the plastic product to be sprayed with the clamping block 9 on one side, and then pulls the sliding sleeve 10, the sliding sleeve 10 moves along the rotating shaft 6, the two gear rings 17 separate, the spring 19 is compressed, and then the sliding sleeve 10 is rotated, and the sliding sleeve 10 drives the rotating shaft 6 to rotate, and adjusts the position of the strip fixing plate 7 that is not in contact with the plastic product, so that the clamping block 9 on the strip fixing plate 7 is aligned with the side of the plastic product, and then releases the sliding sleeve 10, the spring 19 extends, and pushes the sliding sleeve 10 to move, so that the two gear rings 17 are mutually aligned. They are meshed together to fix the rotating shaft 6, and then the staff rotates the bidirectional screw 3 so that the clamping block 9 clamps and fixes the plastic product, and then spraying is carried out. Under the action of the push rod 8, the support frame 4 can be kept away from the plastic product, so that the support frame 4 will not cause obstruction to the plastic product during spraying, and in the process of spraying, the staff pulls the sliding sleeve 10 to separate the two gear rings 17, and then the staff rotates the sliding sleeve 10. With the cooperation of the guide block 22 and the guide groove 21, the sliding sleeve 10 will drive the rotating shaft 6 to rotate, and then the position of the plastic product can be adjusted, which is convenient for all-round spraying of the plastic product and improves the use effect.
[0034] Furthermore, Figure 1 and Figure 2 As shown, a dust cover 15 is provided between the two support frames 4 and on the side of the support frames 4 away from each other. The dust cover 15 is sleeved on the bidirectional screw rod 3. Both ends of the dust cover 15 located between the two support frames 4 are fixed on the side faces of the support frames 4, and one end of the dust cover 15 located on the other side of the two support frames 4 is fixed on the side faces of the corresponding first fixing seats 12. In actual use, the bidirectional screw rod 3 can be covered by the dust cover 15, so that the paint liquid will not adhere to the bidirectional screw rod 3 during the spraying process.
[0035] Furthermore, Figure 2As shown, the dust cover 15 is a corrugated telescopic cover, and when the dust cover 15 is extended or retracted, there is a gap between the inner wall of the dust cover 15 and the side surface of the bidirectional screw rod 3, so that the inner wall of the dust cover 15 will not contact the outer surface of the bidirectional screw rod 3 during use, and the dust cover 15 will not hinder the rotation of the bidirectional screw rod 3.
[0036] Furthermore, Figure 1 As shown, a second fixing seat 13 is installed at the other end of the top of each strip mounting plate 14, and a guide rod 2 is installed between the two second fixing seats 13. The bottom end of each support frame 4 is slidably sleeved on the guide rod 2. Through the cooperation of the guide rod 2 and the support frame 4, the support frame 4 can be guided and limited, so that the support frame 4 remains stable.
[0037] Furthermore, each clamping block 9 is provided with a rubber anti-slip pad on the side away from the top rod 8, so that the plastic product can be clamped more stably and protected at the same time, and the plastic product will not be damaged by being squeezed by the clamping block 9 when fixed.
[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
