Description

Technical Field

[0001] This utility model belongs to the technical field of end cap processing equipment, specifically relating to a surface cleaning device for end cap spraying. Background Technology

[0002] An end cap is a component used to seal the end of a container, isolating it from the internal and external media; it is also called an end cover. End caps of cylindrical containers are generally rotating shells. Based on the shape of their surface, end caps can be classified as convex, conical, flat, and combined types. A convex end cap refers to an end cap with a convex outer surface, such as hemispherical, elliptical, dished, and spherical end caps without folded edges.

[0003] For end caps made of metal structures or other materials, it is particularly important to apply protective coatings to extend their service life. However, before spraying, rust removal or cleaning is usually required. Since most end caps are irregularly shaped, existing cleaning equipment is difficult to meet their needs, while manual cleaning is inefficient and the dust generated during the cleaning process can also affect human health. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art, thereby providing a surface cleaning device for end cap spraying that has a reasonable structural design, can clean the inner surface of many irregular end caps, and is easy to operate and use.

[0005] The purpose of this utility model is achieved as follows: A surface cleaning device for end cap spraying includes a frame, on which a circular support platform is provided. An end cap is placed on the upper surface of the support platform, and a cleaning mechanism is provided below the end cap. The cleaning mechanism includes a main brush and a side brush. The main brush is fixed to the top of a main support rod, and the bottom of the main support rod is fixed to a rotating seat. The side brush is hinged to the top of a lateral support rod. The side of the lateral support rod is connected to a hinge seat on the upper surface of the rotating seat via a hinge shaft near the bottom. The hinge shaft is rotatably connected to the hinge seat and fixedly connected to the lateral support rod. An angle adjustment mechanism is connected to the hinge shaft. The rotating seat is rotatably connected to the frame, and a rotary motor A is connected to the rotating seat.

[0006] Furthermore, the main support rod and the side support rod are telescopic and adjustable support rods, so that the length of the main support rod and the side support rod can be adjusted according to the shape and size of different end caps.

[0007] Furthermore, the telescopic adjustable support rod includes an adjustable support tube and an adjustable support rod. A guide block is provided on the side of the adjustable support rod. The guide block is slidably disposed in a guide groove on the side of the adjustable support tube. The outer side of the guide block extends out of the guide groove and has a lifting thread on its outer surface. The lifting thread meshes with a drive screw. The upper and lower ends of the drive screw are rotatably connected to the outer surface of the adjustable support tube. The adjustable support tube is connected to a rotating seat. The top end of the adjustable support rod is connected to a main brush or a side brush. By rotating the drive screw and engaging with the lifting thread, the guide block can be pushed to move the adjustable support rod along the guide groove, thereby adjusting the length of the main support rod and the side support rod to meet the usage requirements of end caps of different sizes.

[0008] Furthermore, the adjusting support rod of the lateral support rod adopts an elastic telescopic structure. Since the end cap is generally not a standard hemispherical structure, the distance between the inner surface of the end cap and the hinge point at the bottom of the lateral support rod may change continuously during the rotation of the lateral support rod. The elastic telescopic structure can ensure that the side brush and the inner surface of the end cap remain in close contact within a certain range, thereby ensuring the cleaning effect of the side brush on the inner surface of the end cap.

[0009] Furthermore, the adjusting support rod includes a sleeve and an inner rod. The inner rod is slidably disposed inside the sleeve. A compression spring is disposed below the inner rod inside the sleeve. The side brush is connected to the top of the inner rod. The side of the sleeve is hinged to a support on the upper surface of the rotating seat via a hinge shaft near the bottom. During the rotation of the lateral support rod, if the distance between the inner surface of the end cap and the hinge point at the bottom of the lateral support rod decreases, the side brush is pressured to push the inner rod to move inward along its axial direction into the sleeve, compressing the compression spring. Conversely, the compression spring pushes the inner rod and the side brush to move outward along the axial direction of the sleeve, pressing the side brush against the inner surface of the end cap so that the side brush can clean the inner surface of the end cap.

[0010] Furthermore, the angle adjustment mechanism includes a worm gear fixed on a hinge shaft, a worm gear meshing with the worm gear, and the two ends of the worm gear rotatably connected to the upper surface of the rotating seat. The worm gear is connected to a rotary motor B. During the process of the rotary motor A driving the cleaning mechanism to rotate around the vertical axis, the rotary motor B drives the worm gear and the lateral support rod to rotate continuously through the worm gear, so as to adjust the angle between the lateral support rod and the horizontal direction, so that the side brush can gradually clean different positions on the inner surface of the end cap.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model has a cleaning mechanism installed below the end cap on the frame. The cleaning mechanism consists of a main brush and a side brush. The main brush is fixed at the top of the end cap by a main support rod, while the side brush rotates up and down around a horizontally set hinge shaft under the drive of the side support rod. At the same time, the rotary motor A drives the cleaning mechanism to rotate continuously around a vertical axis through a rotating seat. The main brush and the side brush can clean the top and sides of the inner surface of the end cap respectively.

[0013] 2. The main support rod and the side support rod in this utility model adopt a telescopic and adjustable structure, so that the distance between the main brush and the side brush and the rotating seat can be adjusted as needed to meet the usage requirements of end caps of different shapes and sizes.

[0014] 3. In this utility model, the lateral support rod adopts an elastic telescopic structure, which allows the distance between the side brush and the hinge point at the bottom of the lateral support rod to change within a certain range according to the shape of the end cap. During the cleaning process, the side brush and the inner surface of the end cap always remain in close contact, thereby ensuring the cleaning effect of the side brush on the inner surface of the end cap.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment of this utility model, such as Figure 1As shown, a surface cleaning device for end cap spraying includes a frame 1, on which a circular support platform 2 is provided. An end cap 3 is placed on the upper surface of the support platform 2, and a cleaning mechanism is provided below the end cap 3. The cleaning mechanism includes a main brush 4 and a side brush 5. The main brush 4 is fixed to the top of a main support rod 6, and the bottom end of the main support rod 6 is fixed to a rotating seat 8. The side brush 5 is hinged to the top of a lateral support rod 7. The side of the lateral support rod 7 is connected to a hinge seat 10 on the upper surface of the rotating seat 8 via a hinge shaft 9 near the bottom end. The hinge shaft 9 is rotatably connected to the hinge seat 10 and fixedly connected to the lateral support rod 7. An angle adjustment mechanism is connected to the hinge shaft 9. The rotating seat 8 is rotatably connected to the frame 1, and a rotary motor A11 is connected to the rotating seat 8.

[0027] In use, place the end cap 3 with its opening facing down on the support platform 2. The rotation center of the end cap 3 is concentrically set with the vertical axis on the rotating seat 8 connected to the rotary motor A11. Then, start the rotary motor A11, and the rotating seat 8 drives the cleaning mechanism to rotate around the vertical axis. The main brush 4 and side brush 5 on the cleaning mechanism clean the top and side parts inside the end cap 3 respectively. During the rotation of the rotating seat 8, the angle adjustment mechanism drives the side support rod 7 to rotate upward or downward around the hinge shaft 9 through the hinge shaft 9 to clean the sides at different height positions inside the end cap 3, thereby completing the cleaning of the inside of the end cap 3 and facilitating the subsequent spraying operation inside the end cap 3.

[0028] In one embodiment of this utility model, such as Figure 1 As shown, the main support rod 6 and the side support rod 7 are telescopic and adjustable support rods, so that the length of the main support rod 6 and the side support rod 7 can be adjusted according to the shape and size requirements of different end caps.

[0029] In one embodiment of this utility model, such as Figure 1 and Figure 3As shown, the telescopic adjustable support rod includes an adjustable support tube 12 and an adjustable support rod 13. A guide block 14 is provided on the side of the adjustable support rod 13. The guide block 14 is slidably disposed in the guide groove 23 on the side of the adjustable support tube 12. The outer side of the guide block 14 extends out of the guide groove 23 and a lifting thread 15 is provided on the outer side of the guide block 14. The lifting thread 15 meshes with a drive screw 16. The upper and lower ends of the drive screw 16 are rotatably connected to the outer side of the adjustable support tube 12. The adjustable support tube 12 is connected to a rotating seat 8. The top end of the adjustable support rod 13 is connected to a main brush 4 or a side brush 5. By rotating the drive screw 16, the meshing connection between the drive screw 16 and the lifting thread 15 can push the guide block 14 to move the adjustable support rod 13 along the guide groove 23, thereby adjusting the length of the main support rod 6 and the side support rod 7 to meet the usage requirements of end caps of different sizes.

[0030] In one embodiment of this utility model, such as Figure 1 As shown, the adjusting support rod of the lateral support rod 7 adopts an elastic telescopic structure. Since the end cap 3 is generally not a standard hemispherical structure, the distance between the inner surface of the end cap 3 and the hinge point at the bottom of the lateral support rod 7 may change continuously during the rotation of the lateral support rod 7 around the hinge axis 9. The elastic telescopic structure can ensure that the side brush 5 and the inner surface of the end cap 3 remain in close contact within a certain range, thereby ensuring the cleaning effect of the side brush 5 on the inner surface of the end cap 3.

[0031] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the adjusting support rod in the lateral support rod 7 includes a sleeve 17 and an inner rod 18. The inner rod 18 is slidably disposed inside the sleeve 17. A compression spring 22 is disposed below the inner rod inside the sleeve 17. The side brush 5 is connected to the top of the inner rod 18. The side of the sleeve 17 is hinged to the support seat 10 on the upper surface of the rotating seat 8 via a hinge shaft 9 near the bottom end. During the rotation of the lateral support rod 7, if the distance between the inner surface of the end cap 3 and the hinge point at the bottom end of the lateral support rod 7 decreases, the side brush 5 is pressured to push the inner rod 18 to move inward along its axial direction into the sleeve 17, squeezing the compression spring 22. Conversely, the compression spring 22 pushes the inner rod 18 and the side brush 5 to move outward along the axial direction of the sleeve 17, so that the side brush 5 abuts against the inner surface of the end cap 3, so that the side brush 5 cleans the inner surface of the end cap 3.

[0032] In one embodiment of this utility model, such as Figure 1As shown, the angle adjustment mechanism includes a worm gear 19 fixed on the hinge shaft 9, and a worm 20 meshing with the worm gear 19. The two ends of the worm 20 are rotatably connected to the upper surface of the rotating seat 8. The worm 20 is connected to a rotary motor B21. During the process of the rotary motor A11 driving the cleaning mechanism to rotate around the vertical axis, the rotary motor B21 drives the worm gear 19 and the side support rod 7 to rotate continuously through the worm 20, so as to adjust the angle between the side support rod 7 and the horizontal direction, so that the side brush can gradually clean different positions on the inner surface of the end cap 3.

[0033] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
