Description

Technical Field

[0001] The invention belongs to the technical field of paint spraying, and in particular relates to a paint spraying device for producing carbon fiber rollers. Background Art

[0002] A carbon fiber roller is a roller made of carbon fiber composite material, which combines the high strength and light weight of carbon fiber with the bonding properties of a resin matrix. Carbon fiber rollers are used in many industries, especially in those places where weight, strength and durability are high. In the production process of carbon fiber rollers, the prepreg needs to be processed first, and then molding, curing, post-processing and other steps are carried out. In order to improve the aesthetics, wear resistance, corrosion resistance and specific functionality of the carbon fiber roller surface, the carbon fiber roller needs to be painted in the post-processing step.

[0003] The painting process of the carbon fiber roller is not completed in one go, so the painting is usually done manually with machinery, and when spraying paint on the carbon fiber roller, the carbon fiber roller is usually kept in a rotating state to ensure uniform painting. However, when placing the carbon fiber roller, it is often not placed in a fixed position every time. Then when the staff sprays paint, it is inevitable that some paint will be accidentally sprayed onto the roller shaft at both ends of the carbon fiber roller. The roller shaft stained with paint will affect the normal rotation of the carbon fiber roller. Therefore, the staff needs to manually wipe off the paint on the roller shaft in time after painting, which will undoubtedly increase the workload of the staff. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a paint spraying device for carbon fiber roller production.

[0005] The technical solution adopted to solve the above technical problems is: A paint spraying device for carbon fiber roller production, comprising a roller, a roller shaft and a bracket, wherein the roller shaft passes through the roller, and both ends of the roller shaft are respectively mounted on the bracket, a center plate is arranged at the bottom of the bracket, a movement groove is provided on the top wall of the center plate, a movement rod is slidably connected in the movement groove, a push plate is fixedly connected to the top of the movement rod, and top blocks are respectively fixedly connected to both ends of the push plate, and the top block is designed to be arc-shaped at one end away from the push plate, and fixing mechanisms for fixing the position of the roller shaft are respectively arranged on both sides of the bracket; The two ends of the bracket are rotatably connected to the center column, and the two ends of the center column are fixedly connected to the rotating rod. One end of the two rotating rods is commonly fixedly connected to a U-shaped rod, the side wall of the U-shaped rod is against the side wall of the bracket, and a baffle is provided at one end of the rotating rod away from the U-shaped rod.

[0006] Furthermore, the side walls at both ends of the bracket are respectively fixedly connected with buffer blocks, the buffer blocks are made of rubber material, and the side walls of the U-shaped rod are against the side walls of the buffer blocks.

[0007] Furthermore, a pedal is fixedly connected to the top wall of the push plate, and the end of the pedal facing away from the baffle is inclined.

[0008] Furthermore, the fixing mechanism includes a side panel, a transverse plate, a top plate and a plurality of telescopic springs. The side wall of the side panel is against the roller shaft, the transverse plate is fixedly connected to the bottom of the side panel, the top plate is fixedly connected to one end of the transverse plate away from the side panel, both ends of the top plate are arc-shaped, the top plate is located in front of the top block, and the plurality of springs are respectively fixedly connected to the side wall of the side panel facing the bracket, and the other ends of the plurality of springs are fixedly connected to the side wall of the bracket.

[0009] Furthermore, a groove is provided on the side wall of the side panel facing the roller shaft, the upper end of the groove is open, and the bottom of the groove is arc-shaped.

[0010] Furthermore, the side wall of the pedal away from the inclined end is fixedly connected with a connecting rod, and the connecting rod is fixedly connected with a displacement rod at one end away from the pedal. The displacement rod is designed as a "U" shape, and blocking plates are fixedly connected at both ends of the displacement rod, and the side walls of the blocking plates are against the side walls of the U-shaped rod.

[0013] Furthermore, the side walls at both ends of the push plate are respectively fixedly connected with magnetic sheets, and the moving groove is made of magnetic metal as a whole.

[0014] Through the above technical solution, the beneficial effects of the present invention are as follows: The present invention provides side panels with grooves at both ends of the roller shaft, so that the roller and the roller shaft are inserted into the two side panels along the grooves, thereby determining the position of the roller, and facilitating the staff to spray paint on it. In addition, during the painting process, the staff can buckle the roller shaft with a baffle to effectively prevent paint from splashing onto the roller shaft, thereby ensuring the stability of the carbon fiber roller during subsequent use. At the same time, during the painting process, the side panels will also leave the roller shaft to avoid affecting the rotation of the roller shaft, thereby making the painting more uniform. The present invention provides a push plate and a pedal at the bottom of the bracket, so that the staff can push the pedal by stepping on it, so that the side panel leaves the roller shaft and the baffle is buckled on the roller shaft. Then the staff can spray paint on the roller with a handheld spray gun. In addition, a rolling wheel can be additionally provided on the bracket to make the roller rotate automatically during the painting process, making the painting process more convenient. Only one staff member is needed to quickly operate the whole process, which effectively saves human resources. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] like Figure 1-Figure 5 As shown, the present embodiment provides a paint spraying device for carbon fiber roller production, including a roller 1, a roller shaft 2 and a bracket 3, the roller shaft 2 passes through the roller 1, and the two ends of the roller shaft 2 are respectively mounted on the bracket 3, a center plate 4 is arranged at the bottom of the bracket 3, a movement groove 5 is opened on the top wall of the center plate 4, a movement rod 6 is slidably connected in the movement groove 5, a push plate 7 is fixedly connected to the top of the movement rod 6, and magnetic sheets 26 are respectively fixedly connected to the side walls at both ends of the push plate 7, the movement groove 5 is made of magnetic metal as a whole, and the magnetic sheets 26 at both ends of the push plate 7 ensure that the push plate 7 is fixed at the current position when it moves to the ends of the movement groove 5.

[0019] The top wall of the push plate 7 is fixedly connected to a pedal 14, and the end of the pedal 14 facing away from the baffle 12 is inclined. The side wall of the pedal 14 away from the inclined end is fixedly connected to a connecting rod 20, and the end of the connecting rod 20 away from the pedal 14 is fixedly connected to a displacement rod 21. The displacement rod 21 is a "U"-shaped design, and the two ends of the displacement rod 21 are respectively fixedly connected to a blocking plate 22, and the side wall of the blocking plate 22 is against the side wall of the U-shaped rod 11, so that Figure 2 As can be seen from the figure, the blocking plate 22 is "L"-shaped, which makes it easier to block the rotation of the rotating rod 10.

[0020] Both ends of the push plate 7 are fixedly connected with a top block 8, and the top block 8 is designed to be arc-shaped at one end away from the push plate 7. Fixing mechanisms for fixing the position of the roller shaft 2 are respectively installed on both sides of the bracket 3, and the fixing mechanisms include a side panel 15, a transverse plate 16, a top plate 17 and a plurality of telescopic springs 18. The side wall of the side panel 15 is against the roller shaft 2, and a groove 19 is provided on the side wall of the side panel 15 facing the roller shaft 2. The upper end of the groove 19 is designed to be open, and the bottom of the groove 19 is designed to be arc-shaped. Since the roller shaft 2 is cylindrical, the bottom of the groove 19 is preferably also set to be semicircular.

[0021] The transverse plate 16 is fixedly connected to the bottom of the side panel 15, and the top plate 17 is fixedly connected to one end of the transverse plate 16 away from the side panel 15. Both ends of the top plate 17 are arc-shaped. The top plate 17 is located in front of the top block 8. Several telescopic springs 18 are respectively fixedly connected to the side wall of the side panel 15 facing the bracket 3, and the other ends of the several telescopic springs 18 are fixedly connected to the side wall of the bracket 3. The force applied to the side panel 15 by the telescopic springs 18 will keep the two side panels 15 closer to the bracket 3.

[0022] The two ends of the bracket 3 are rotatably connected to the center column 9, and a torsion spring 23 is wound around the outside of the center column 9. One end of the torsion spring 23 is fixedly connected to the side wall of the bracket 3, and the other end is fixedly connected to the side wall of the rotating rod 10. The force applied to the rotating rod 10 by the torsion spring 23 will cause the rotating rod 10 to drive the baffle 12 to always have a force buckled on the roller shaft 2.

[0023] The two ends of the center column 9 are respectively fixedly connected with rotating rods 10, and one end of the two rotating rods 10 is commonly fixedly connected with a U-shaped rod 11, and the side walls of the U-shaped rod 11 are abutted against the side walls of the bracket 3. The side walls of the two ends of the bracket 3 are respectively fixedly connected with buffer blocks 13, and the buffer blocks 13 are made of rubber. The side walls of the U-shaped rod 11 are abutted against the side walls of the buffer blocks 13. The setting of the buffer blocks 13 can effectively prevent the U-shaped rod 11 from hitting the side walls of the bracket 3.

[0024] A baffle 12 is provided at one end of the rotating rod 10 away from the U-shaped rod 11, and extension plates 24 are fixedly connected at both ends of the baffle 12. The extension plate 24 is fixedly connected to the end of the rotating rod 10 away from the U-shaped rod 11, and a through groove 25 is opened on the side wall of the extension plate 24. The baffle 12 is arched. Since the roller shaft 2 is cylindrical, in order to fit the side wall of the roller shaft 2, the baffle 12 is preferably arched. Moreover, since rotating wheels that facilitate the rotation of the roller shaft 2 are sometimes provided on the bracket 3, the through groove 25 can avoid friction and collision between the extension plate 24 and these rotating wheels.

[0025] The working principle of this embodiment is as follows: in the initial state, the two side panels 15 are closer to the bracket 3 under the action of the telescopic spring 18, and then the staff can put the roller 2 and the roller 1 on the bracket 3 along the groove 19, and then the staff can step on the pedal 14, and the push plate 7 at the bottom of the pedal 14 will move forward along the motion groove 5, thereby driving the top blocks 8 at both ends of the push plate 7 to move forward, and the arc-shaped top blocks 8 will push the top plate 17 to both sides, so that the top plate 17 drives the lateral blocks and the side panels 15 to move to both sides, so that the telescopic spring 18 is stretched, and the side panels 15 will leave the roller 2; At the same time, the forward movement of the pedal 14 will also drive the connecting rod 20 and the displacement rod 21 to move forward, and the blocking plate 22 fixedly connected to the displacement rod 21 will leave the U-shaped rod 11. Without the restriction of the U-shaped rod 11, the rotating rod 10 will rotate around the central column 9 under the action of the torsion spring 23, so that the extension plate 24 drives the baffle 12 to buckle on the roller shaft 2, thereby protecting the roller shaft 2. At this time, the staff does not need to worry about the paint being sprayed onto the roller shaft 2 when spraying paint on the roller 1 with a spray gun.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
