Description

Technical Field

[0001] The invention relates to the technical field of polishing brushes, in particular to a spiral glass screen polishing brush. Background Art

[0002] When polishing glass products, the hair bundles on the ordinary brush disc that are perpendicular to the brush disc can well meet the polishing requirements of flat products. However, when polishing curved products, the hair bundles on the ordinary brush disc that are perpendicular to the brush disc cannot fully take care of all directions of the curved products, resulting in unsatisfactory curved surface polishing effects. To solve this problem, it is necessary to replace the polishing brush with bristles tilted at a certain angle relative to the brush disc, which makes the polishing process of glass products cumbersome, inefficient and costly. In addition, the glass structure powder peeled off during the grinding process will be adsorbed on the peeling surface, and thus needs to be blown away with the help of an additional blowing structure. However, the airflow to the powder in the grinding center is reduced due to the obstruction caused by the grinding brush, and then the powder is polished on the glass with the grinding brush, resulting in a reduction in the grinding effect of the glass surface. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a spiral glass screen polishing brush, which solves the problems of adjusting the bristle angle and blowing away glass powder.

[0004] To achieve the above object, the present invention provides the following technical solution: a spiral glass screen polishing brush, comprising a clamping handle, a bristle assembly and a central shaft, wherein the central shaft is connected to the clamping handle and establishes a fixed foundation for the bristle assembly, and the central shaft comprises: The inner cavity of the mounting part is opened at the center of the central shaft and is opened in a columnar shape, and is passed through from left to right and ends at the connection with the clamping handle; The fixed base body has a first surface and a second surface which are adjacent and complementary to each other and constitute the outer wall of the central shaft rod, the first surface is provided with a fixed notch with an equal inner diameter in a rotational direction, and the second surface is complementary to the first surface and is provided with a plurality of gas passages extending toward the center of the inner cavity of the insert; An angle adjustment auxiliary part is placed in the inner cavity of the placement part and acts on the bristle assembly. It has a ring plate that slides on the side wall of the inner cavity of the placement part. A rod extending toward the first surface is vertically installed on the ring plate. The rod is in a sleeve shape and an auxiliary ring placed in a fixed groove is arranged at its upper end. The auxiliary ring is clamped on the bristle assembly.

[0005] In a specific embodiment, the central shaft further comprises: The air overflow powder removal part has a front-back symmetric structure and is placed at the central position of the angle adjustment auxiliary part. The air overflow powder removal part includes a basic structure plate and a profiling plate installed on the basic structure plate. The profiling plate has a first structural end and a second structural end. An air overflow guiding strip is installed on the structure body where the basic structure plate is separated from the profiling plate connection to guide the air flow output angle and the air flow to span and diffuse; The air overflow guiding strip extends along the left-right horizontal direction on the basic structure plate and is composed of a bottom plate attached to the basic structure plate and a special-shaped plate placed on the bottom plate. The special-shaped plate includes end blocks that are symmetric in the front and back and increase in height and reach the peak value between the ends of the bottom plate. A connecting plate that extends from a single end block to the central axis of the bottom plate and then extends from the central axis of the bottom plate to the other end block is clamped between the two end blocks. The connecting plate forms two air flow nests clamped between the two end blocks.

[0006] In a specific embodiment, it is specifically described that the basic structure plate is semi-circular, and its front and back are symmetrically inscribed in the ring plate to establish an air guiding channel with the ring plate structure. The profiling plate is placed in the air guiding channel to establish a channel for the outside to transport air flow to the air guiding channel; The profiling plate conforms to the basic structure plate. The first structural end and the second structural end establish paths for air flow to enter and exit. The first structural end is parallel to the radial center line of the basic structure plate, and an air outlet is opened thereon. The second structural end is perpendicular to the radial center line of the basic structure plate and is horizontal with the basic structure plate, and an air supply port is opened thereon. The air supply port penetrates the basic structure plate and extends horizontally along its axis. An air passing groove connecting the air outlet and the air supply port is opened inside the profiling plate, and the number of air passing grooves is adapted to the number of air outlets opened.

[0007] In a specific embodiment, it is specifically described that the center line of the air outlet opening intersects the structure where the end block extends towards the ring plate. The air supply port is semi-circular, and two symmetrically arranged profiling plates in the front and back are connected to form a complete and connected air supply port.

[0008] In a specific embodiment, it is specifically described that the brush hair assembly includes a clamping sleeve installed inside the auxiliary ring. The clamping sleeve has a left-right symmetric V-shaped structure, and the brush hair is placed in the clamping gap between the symmetric structures of the clamping sleeve; Through holes for guiding the air flow to the fixed base body are opened on the ring plate, and a number of guiding strips are installed on the structural surface of the ring plate relative to the fixed base body and are embedded in the fixed base body to guide the movement of the ring plate.

[0009] In a specific embodiment, it is specifically described that the rod is composed of an inner rod and an outer rod. The inner rod is connected to the bottom surface of the auxiliary ring and drives synchronously. The outer rod is installed on the inner wall of the fixed base body. The inner diameter of the outer rod is larger than the diameter of the outer rod, and an elastic member is arranged on the inner wall of the outer rod; The width of the auxiliary ring is smaller than the width of the fixed notch to create a reserved space for left and right inclination.

[0010] In a specific embodiment, it is specifically described that the air passage opened on the second surface penetrates the thickness of the second surface structure, generating a path for the airflow to output outward from the second surface along the air guiding channel.

[0011] Compared with the prior art, the present invention provides a spiral glass screen polishing brush. Based on the specific problems of existing angle adjustment and dust adhesion, it has the following beneficial effects: In the technical solution disclosed by the present invention, the angle adjustment auxiliary member for adjusting the angle of the brush bristles and the overwind dust removal member acting on the glass powder are centrally arranged in the central shaft rod. That is, the self-adjustment of the angle of the brush bristles is generated from the inside of the polishing brush. First, the polishing of the special-shaped structure of the glass is adapted to the angle, and during the polishing process, a dust removal airflow output from the central shaft rod to the adjacent brush bristles can be generated, thereby generating an airflow layer on the glass surface, reducing the adhesion viscosity of the glass to the powder, and effectively driving away the glass powder under polishing.

[0012] Based on the main problems to be solved regarding the angle of the brush bristles and the dust viscosity, this solution also considers the transportation path of the airflow in the central shaft rod after it is generated. The central shaft rod is arranged in a long strip shape. After unidirectionally supplying air into it, the area where the gas overflows is self-evident for the dust removal effect. Based on this, this solution uses the setting method of arranging end blocks at both ends of the connecting plate with overwind guiding strips. First, after the airflow comes into contact with the end blocks, it generates a following movement and moves along its tangent direction. Based on the fact that the diameter of the air passage on the second surface cannot meet the outpouring of all the airflow, that is, part of the airflow moves along the connecting plate towards the lower end block and generates a movement path of moving along its tangent again, generating two dispersion guiding paths for the airflow, expanding the area where the airflow is dispersed and output on the second surface, and increasing the dust removal effect of a single air supply.

[0013] Based on the adjustment requirement of the angle of the brush bristles, during the adjustment of the brush bristles by the ring plate, a synchronous adjustment effect between the structures is generated based on the rod member. That is, the inner rod and the outer rod need to generate a relative angle adjustment. The installation of the elastic member on the outer rod can first effectively limit the adjustment angle range of the inner rod, reducing the probability of structural collision of the inner rod inside the outer rod and resulting in maintenance, and secondly, the installation of the elastic member on the inner wall of the outer rod also protects the inner wall of the outer rod without affecting the required rotation angle of the inner rod, reducing the probability of damage to the overall structure.

Detailed implementation manners

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1-9, in the embodiments of the present invention, the tufts perpendicular to the brush disk on an ordinary brush disk can well meet the polishing requirements of flat products. However, when polishing curved products, the tufts perpendicular to the brush disk on an ordinary brush disk cannot comprehensively cover all aspects of the curved product, resulting in an unsatisfactory curved surface polishing effect. Additionally, the glass structure powder peeled off during the grinding process will adsorb on the peeled surface, so an additional blowing structure needs to be used to blow it away. However, the airflow received by the powder at the grinding center is reduced due to the blockage caused by the grinding brush, and then the powder will grind on the glass with the grinding brush, resulting in a reduction in the grinding effect on the glass surface. That is, the above description is summarized as a new structure proposed for the purpose of adjusting the angle of the bristles 22 and blowing away the glass powder in this solution. In this embodiment, a spiral glass screen polishing brush is proposed, and the angle adjustment auxiliary part 6 for adjusting the angle of the bristles 22 and the overflow air powder removal part 7 acting on the glass powder are centrally arranged in the central shaft rod 3, that is, the self-adjustment of the angle of the bristles 22 is generated from the inside of the polishing brush. First, the polishing that adapts to the special-shaped structure of the glass is carried out, and during the polishing process, a powder removal airflow output from the central shaft rod 3 to the adjacent bristles 22 can be generated, and then an airflow layer is generated on the glass surface, reducing the adhesion viscosity of the glass to the powder, thereby effectively driving away the polished glass powder.

[0018] A spiral glass screen polishing brush proposed in this embodiment has the structures provided in existing polishing brushes, including a clamping handle 1. Among them, the bristle assembly 2 acting on the glass surface and the central shaft rod 3 are the specific improved structures of this solution. The bristle assembly 2 is arranged on the central shaft rod 3, and the central shaft rod 3 is connected to the clamping handle 1. Existing mechanical equipment for supplying air into the central shaft rod 3 can be installed on the clamping handle 1, and in order to meet the air intake requirement, an air inlet hole is opened on the clamping handle 1.

[0019] The central shaft rod 3 includes a cylindrical component cavity 4 opened at the central position of the central shaft rod 3. The component cavity 4 penetrates left and right and terminates at the connection with the clamping handle 1, which serves as the installation foundation for the subsequent components, achieving the structural integration of the central shaft rod 3. The outer wall of the central shaft rod 3 formed by the fixed base body 5 has adjacent and complementary first surface 51 and second surface 52. The thickness of the first surface 51 and the second surface 52 is the structural thickness of the central shaft rod 3. Fixed notches 53 with equal inner diameters are spirally formed on the first surface 51. The brush hair assembly 2 is placed in the fixed notches 53. The second surface 52 is complementary to the first surface 51 and is provided with a number of air passage channels 54 extending towards the center of the component cavity 4. The air passage channels 54 opened on the second surface 52 penetrate the structural thickness of the second surface 52, generating a path for the airflow to output outside the second surface 52 along the air guiding channel 74. Considering the problem of adjusting the angle of the brush hair 22, the angle adjustment auxiliary member 6 is placed in the component cavity 4 and acts on the brush hair assembly 2. It has an annular plate 61 sliding on the side wall of the component cavity 4. Through holes 64 for guiding the airflow towards the fixed base body 5 are formed on the annular plate 61. A number of guiding strips 65 embedded in the fixed base body 5 for guiding the movement of the annular plate 61 are installed on the structural surface of the annular plate 61 relative to the fixed base body 5. The guiding strips 65 are in the shape of strips extending left and right. A rod 62 extending towards the first surface 51 is vertically installed on the annular plate 61. The rod 62 is in a sleeved shape and an auxiliary ring 63 placed in the fixed notch 53 is provided at its upper end. The width of the auxiliary ring 63 is smaller than the width of the fixed notch 53, generating a reserved space for left and right inclination. The auxiliary ring 63 clamps the brush hair assembly 2. Based on the synchronous movement of the brush hair assembly 2 and the auxiliary ring 63, and the movement of the auxiliary ring 63 is driven by the rod body installed on the annular plate 61. That is, by completing the left and right movement of the annular plate 61, the existing angle of the brush hair assembly 2 can be changed. That is, the movement drive of the annular plate 61 can be realized by using a cylinder installed on the clamping handle 1. The cylinder is installed on the structural surface of the clamping handle 1 relative to the fixed base body 5. By controlling the pushing length of the cylinder on the annular plate 61, the angle control of the brush hair assembly 2 can be realized. In addition, the basic structural plate 71 is threadedly connected or rigidly connected to the clamping handle 1 to drive the basic structural plate 71 when the clamping handle 1 is driven to rotate by an external device.

[0020] The bristle assembly 2 includes a clamping sleeve 21 installed within the auxiliary ring 63. The clamping sleeve 21 has a left-right symmetric V-shaped structure. The bristles 22 are placed in the clamping gap between the symmetric structures of the clamping sleeve 21. Its V-shaped structure gradually adheres from the center of the auxiliary ring 63 towards the side wall. During the adhesion process, the auxiliary ring 63 exerts a pushing effect on the structure of the clamping sleeve 21, thereby clamping the bristles 22. The rod member 62 is composed of an inner rod 621 and an outer rod 622. The inner rod 621 is connected to the bottom surface of the auxiliary ring 63 and is synchronously driven. The outer rod 622 is installed on the inner wall of the fixed base body 5. The inner diameter of the outer rod 622 is larger than its diameter, and an elastic member 623 is provided on the inner wall of the outer rod 622. The elastic member 623 is symmetrically arranged up and down with the radial axis of the outer rod 622 as the symmetry center line. It includes a mounting seat 6231 and an adhering layer 6232 provided on the mounting seat 6231. The adhering layer 6232 is adapted to the outer diameter value of the inner rod 621 and adheres to the side wall of the inner rod 621. A compression space for the inner rod 621 to compress the adhering layer 6232 is reserved between the adhering layer 6232 and the mounting seat 6231 through a compression spring.

[0021] Regarding the problem of glass dust adhering to the polished glass, this solution specifically uses an overflow air impurity removal component to solve it. It has a front-back symmetric structure and is placed at the central position of the angle adjustment auxiliary component 6. The overflow air impurity removal component includes a basic structure plate 71 and a profiling plate 72 installed on the basic structure plate 71. The profiling plate 72 has a first structural end and a second structural end. The basic structure plate 71 is semi-circular and is symmetrically inscribed in the ring plate 61 front and back to establish an air passage guiding channel 74 with the structure of the ring plate 61. The profiling plate 72 is placed in the air passage guiding channel 74 to establish a channel for the outside to convey air into the air passage guiding channel 74. The profiling plate 72 conforms to the basic structure plate 71. The first structural end and the second structural end establish paths for air to enter and exit. The first structural end is parallel to the radial center line of the basic structure plate 71, and an air outlet 75 is opened thereon. The second structural end is perpendicular to the radial center line of the basic structure plate 71 and is horizontal with the basic structure plate 71, and an air supply port 76 is opened thereon. The air supply port 76 is semi-circular. Two front-back symmetric profiling plates 72 are connected to form a complete and connected air supply port 76. The air supply port 76 penetrates the basic structure plate 71 and extends horizontally along its axis direction. An air passage groove 77 connecting the air outlet 75 and the air supply port 76 is opened inside the profiling plate 72. The number of air passage grooves 77 is adapted to the number of air outlets 75 opened.

[0022] Based on the main problems to be solved regarding the angle of the bristles 22 and the viscosity of the dust, this solution also considers the conveying path of the air flow in the central shaft rod 3 after it is generated. The central shaft rod 3 is arranged in a long strip shape. After unidirectionally supplying air into it, the area where the gas overflows is self-evident for the effect of dust removal. Based on this, an air overflow guiding strip 73 is installed on the structure where the basic structure plate 71 is disengaged from the profiling plate 72 to guide the output angle of the air flow and the diffusion of the air current across. The air overflow guiding strip 73 extends along the left-right horizontal direction on the basic structure plate 71. It consists of a bottom plate 731 attached to the basic structure plate 71 and a special-shaped plate placed on the bottom plate 731. The special-shaped plate includes end blocks 732 that are symmetric in the front and back and increase in height and reach the peak value between the ends of the bottom plate 731. The center line of the opening of the air outlet 75 intersects the structure extending towards the annular plate 61 of the end block 732 to satisfy the collision of the air flow by the end block 732 and generate the flow guiding of the air flow based on the end block 732. A connecting plate 733 is clamped between the two end blocks 732 and extends from a single end block 732 towards the central axis of the bottom plate 731 and then extends from the central axis of the bottom plate 731 towards the other end block 732. The connecting plate 733 forms an air flow cavity channel clamped between the two end blocks 732. The air flow cavity channel undertakes the role of reducing the air pressure generated by the large amount of air flow surging out on the air passage 54 of the second surface 52. It generates an air flow reserve and reduces the impact of the air flow on the air passage 54. After the air flow enters the air guiding channel 74 from the profiling plate 72, it first comes into contact with the end block 732 and then generates a following movement and moves along its tangent direction. Since the diameter of the air passage 54 on the second surface 52 cannot satisfy the gushing out of all the air flow, that is, part of the air flow moves along the connecting plate 733 towards the lower end block 732 and generates a movement path of moving along its tangent again, generating two kinds of dispersion guiding paths for the air flow, expanding the area of the air flow dispersed output on the second surface 52, and increasing the dust removal effect of a single air supply. And for the external device that conveys the air flow from the air supply port 76, it can be installed at the central position of the clamping handle 1, and the installation position of the air supply device is installed on the clamping handle 1 through a rolling bearing to avoid synchronous rotation with the clamping handle 1.
