Description

Technical Field

[0001] This utility model relates to the field of automatic processing and production of twisted brush products, and in particular to an automatic production device for twisted brush heads. Background Technology

[0002] A twisted wire brush, also known as a twisted filament brush, is a cleaning tool made by twisting a skeleton (metal wire) and bristles together. It has a simple structure, typically spiral-shaped, with the bristles evenly distributed along the skeleton to form a cylindrical brush body. It has a wide range of applications, including cleaning in the medical industry and laboratories, polishing and grinding precision parts, and cleaning and filtering pipelines in industrial fields.

[0003] The production steps of twisted wire brushes generally include fixed-length wire taking, positioning and laying, twisting and locking, and fixed-length cutting. Existing technology can produce twisted wire brushes manually or with semi-automatic machines, but almost every production step in the existing technology requires manual intervention and adjustment, resulting in a high product defect rate and low efficiency.

[0004] It is evident that existing technologies suffer from high defect rates and low efficiency in the production of twisted wire brushes. Utility Model Content

[0005] This invention provides an automatic production device for twisted brush heads, which solves the problems of high defect rate and low efficiency in the production of twisted brushes in the prior art.

[0006] This utility model provides an automatic production device for twisted wire brush heads, which is used to produce twisted wire brush heads. The twisted wire brush head includes multiple metal wires and brush filaments wound around the metal wires. It includes a twisting assembly, a first conveying assembly, a second conveying assembly, and a brush filament assembly assembly;

[0007] The first conveying assembly, the second conveying assembly, and the torsion assembly are spaced apart along the first direction. The bristle assembly is located on the first side of the first conveying assembly along the second direction, which is perpendicular to the first direction and lies in the same plane as the first direction. The first conveying assembly has a plurality of first through holes, the axial direction of which extends along the first direction. The second conveying assembly is located between the first conveying assembly and the torsion assembly. The second conveying assembly has a plurality of second through holes, which are corresponding to the plurality of first through holes. A plurality of metal wires are threaded through the plurality of first through holes and the plurality of second through holes.

[0008] The first conveying component can move towards the torsion component between the initial position and the target position under the action of external force, so as to drive multiple metal wires to move towards the torsion component through multiple first through holes and multiple second through holes;

[0009] The end of the twisting assembly facing the second conveying assembly is provided with a wire clamping mechanism for clamping one end of multiple wires;

[0010] The bristle assembly includes a bristle clamping mechanism for clamping the bristles and threading them through at least one gap between a plurality of metal wires, and a torsion assembly that can be driven to rotate about its own axis to torsionally fix the bristles threaded in the at least one gap within the plurality of metal wires.

[0011] This invention, through a twisting assembly, a first conveying assembly, a second conveying assembly, and a bristle assembly assembly, enables the automatic feeding, assembly, and twisting and locking of the metal wire and bristles in the twisted brush head in one continuous process, greatly improving the production efficiency of twisted brushes. Furthermore, the metal wire in this invention is conveyed forward through multiple first and second through holes, giving the metal wire high tension and stability, making it less prone to bending during conveying, improving the accuracy and efficiency of bristle assembly, and thus reducing the defect rate of twisted brushes.

[0012] Optionally, the first conveying assembly includes a first body and a second body. The first body has a mounting groove, and the second body is embedded in the mounting groove. The bottom of the mounting groove has a plurality of first grooves, and the sidewall of the second body facing the first groove has a plurality of second grooves. The plurality of first grooves and second grooves surround to form a plurality of first through holes.

[0013] Optionally, the first body and the second body can be driven to move in opposite directions or away from each other to change the diameter of the plurality of first through holes.

[0014] Through the above-described structure, this utility model embodiment can change the diameter of the first through hole by altering the relative positions of the first main body and the second main body, thereby adapting to different specifications of metal wires and producing twisted brush heads of different specifications. Furthermore, the relatively movable first and second main bodies can adaptively adjust the hole diameter according to the diameter of the metal wire when the metal wire is located in the first through hole, in order to clamp the metal wire. This can prevent the metal wire from bending or breaking during the conveying process, improve the conveying speed, and thus improve the yield and production efficiency of the twisted brush heads.

[0015] Optionally, the second conveying assembly is provided with a cutting mechanism on the side opposite to the first conveying assembly. The cutting mechanism includes an annular cutter. The annular cutter is disposed at one end of a plurality of second through holes opposite to the first conveying assembly. The annular cutter can be driven to move radially from the first position to the second position along the plurality of second through holes.

[0016] When the annular cutter is in the first position, the axis of the multiple second through holes is located inside the annular structure of the annular cutter. When the annular cutter is in the second position, the axis of the multiple second through holes is located outside the annular structure of the annular cutter.

[0017] Optionally, the automatic production device for twisted brush heads also includes a first bracket and a second bracket; the first bracket and the second bracket are located on both sides of the brush bristle clamping mechanism along the first direction, and can be driven to move toward or away from the second conveying component. Both the first bracket and the second bracket have a toothed structure. The first bracket and the second bracket are used to be inserted between multiple metals to support at least one gap.

[0018] This utility model embodiment supports the gaps between multiple metal wires by using a first bracket and a second bracket, which can avoid the problem of multiple metal wires overlapping due to their own weight, making it difficult to insert the brush filaments. This improves the accuracy and efficiency of brush filament insertion, and further improves the yield and production efficiency of twisted brush heads.

[0019] Optionally, the wire clamping mechanism includes a clamping part, an elastic element, and a sleeve;

[0020] The clamping part is trumpet-shaped and includes a first clamping flap and a second clamping flap. An elastic element is disposed between the first clamping flap and the second clamping flap. The first clamping flap and the second clamping flap can open or close under the action of external force.

[0021] The sleeve is fitted onto the outer wall of the clamping part and can move between the clamping position and the non-clamping position along the extension direction of the clamping part;

[0022] When the sleeve is in the clamping position, the first clamping flap and the second clamping flap are squeezed and closed by the sleeve, and multiple metal wires are clamped between the first clamping flap and the second clamping flap.

[0023] This utility model embodiment uses the above-described structure to clamp the metal wire, which has a stable and firm clamping force, effectively preventing the metal wire from falling off during the twisting process, and further improving the yield and production efficiency of the twisted brush head.

[0024] Optionally, the automatic production device for twisted brush heads also includes a filament feeding assembly, which is located on the second side of the first conveying assembly along the second direction. The filament feeding assembly includes a feeding table and a filament cutting knife.

[0025] The feeding platform has a first feeding hole and a second feeding hole distributed along the direction of gravity. The first feeding hole and the second feeding hole penetrate the first side wall and the second side wall opposite to each other on the feeding platform. The filament cutting knife is located at the outlet end of the first feeding hole and the second feeding hole. The filament cutting knife can move from the non-cutting position to the cutting position along the direction of gravity.

[0026] The non-cutting position is configured such that the brush filament cutter is suspended above the first feeding hole and the second feeding hole, and the cutting position is configured such that the brush filament cutter is blocked at the outlet end of the first feeding hole and the second feeding hole.

[0027] The present invention, through the above-described structure, enables automatic feeding and cutting of brush filaments, further improving the automation level and production efficiency of the automatic production device for twisted brush heads.

[0028] Optionally, the automatic production device for twisted brush heads also includes a filament transport assembly, which includes a base and a filament clamp. The base can be driven to move toward or away from the filament feeding assembly. The filament clamp is rotatably mounted on the base and can be driven to rotate about a rotation axis.

[0059] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0060] Please see Figure 1 and Figure 2This utility model provides an automatic production device 1 for producing twisted brush heads. The twisted brush head includes multiple metal wires 2 and brush filaments wound around the metal wires. It includes a twisting component 13, a first conveying component 11, a second conveying component 12, and a brush filament assembly component 14.

[0061] The first conveying assembly 11, the second conveying assembly 12, and the torsion assembly 13 are arranged at intervals along the first direction L1. The bristle assembly 14 is located on the first side of the first conveying assembly 11 along the second direction L2. The second direction L2 is perpendicular to the first direction L1 and is located in the same plane as the first direction L1.

[0062] Please see Figure 2 The first conveying assembly 11 has a plurality of first through holes 101, the axial direction of which extends along a first direction L1. The second conveying assembly 12 is located between the first conveying assembly 11 and the torsion assembly 13, and the second conveying assembly 12 has a plurality of second through holes 102 (e.g., ...). Figure 4 As shown, multiple second through holes 102 are correspondingly arranged with multiple first through holes 101. Multiple metal wires 2 are threaded through the multiple first through holes 101 and the multiple second through holes 102.

[0063] The first conveying component 11 can move towards the torsion component 13 between the initial position and the target position under the action of external force, so as to drive multiple metal wires 2 to move towards the torsion component through multiple first through holes 101 and multiple second through holes 102.

[0064] The twisting assembly 13 is provided with a wire clamping mechanism 130 at one end facing the second conveying assembly 12, which is used to clamp one end of a plurality of wires 2.

[0065] The bristle assembly 14 includes a bristle clamping mechanism 140 (e.g., ... Figure 7 As shown, the device is used to clamp brush filaments and thread them through at least one gap between multiple metal wires. The torsion assembly 13 can be driven to rotate about its own axis to torsionally fix the brush filaments threaded through the at least one gap within the multiple metal wires. This invention is not limited to the type of brush filament clamping mechanism; any clamp capable of clamping brush filaments and feeding them into the aforementioned gap does not deviate from the scope of this invention. In one embodiment, the clamping mechanism 140 includes an upper clamping plate and a lower clamping plate that can move relative to each other, both of which are L-shaped.

[0066] This invention, through the twisting assembly 13, the first conveying assembly 11, the second conveying assembly 12, and the bristle assembly 14, enables the automatic feeding, assembly, and twisting and locking of the metal wire and bristles of the twisted brush head in one continuous process, greatly improving the production efficiency of twisted brushes. Furthermore, the metal wire in this invention is conveyed forward through multiple first through holes 101 and multiple second through holes 102, giving the metal wire high tension and stability, making it less prone to bending during conveying, improving the accuracy and efficiency of bristle assembly, and thus reducing the defect rate of twisted brushes.

[0067] Those skilled in the art will understand that the present invention is not limited in the quantity of metal, as long as it is greater than or equal to 2. The number of first through holes 101 and second through holes 102 is not limited, as long as they can accommodate the corresponding metal wires, they do not depart from the scope of the embodiments of the present invention.

[0068] In one implementation, please refer to Figures 2 to 3a and combined Figure 1 Understandably, the first conveying assembly 11 includes a first body 111 and a second body 112. The first body 111 has a mounting groove 115, and the second body 112 is embedded within the mounting groove 115. The bottom of the mounting groove 115 has a plurality of first grooves 113, and the sidewall of the second body 112 facing the first grooves 113 has a plurality of second grooves 114. The plurality of first grooves 113 and second grooves 114 surround and form a plurality of first through holes 101. In a further embodiment, the first body 111 and the second body 112 can be driven to move towards or away from each other to change the aperture of the plurality of first through holes 101. Please refer to [link to previous document]. Figure 2 In one embodiment, the first conveying assembly 11 is driven to move toward the second conveying assembly 12 by a drive unit 116, and the second body 112 in the first conveying assembly 11 moves relative to the first body 111 by a drive unit 117.

[0069] The shape and number of the first groove 113 and the second groove 114 are not limited. In one embodiment, the first groove 113 is a V-shaped groove and the second groove 114 is an arc-shaped groove. Other alternative embodiments may also use elliptical grooves, rectangular grooves, etc.

[0070] In one embodiment, there are three first grooves 113. The first groove 113 located in the middle is deeper and forms a larger first through hole 101 with the corresponding second groove 114 to accommodate two side by side metal wires. The other two first through holes 101 each accommodate one metal wire. In this embodiment, the finished twisted brush head is formed by twisting four metal wires, which has better rigidity and is not easy to bend.

[0071] Through the above-described structure, this utility model embodiment can change the diameter of the first through hole 101 by altering the relative positions of the first body 111 and the second body 112, thereby adapting to different specifications of metal wires and producing twisted brush heads of different specifications. Furthermore, the relatively movable first body 111 and second body 112 can adaptively adjust the diameter of the hole according to the diameter of the metal wire 2 when the metal wire 2 is located in the first through hole 101, in order to clamp the metal wire. This can prevent the metal wire from bending or breaking during the conveying process, improve the conveying speed, and thus improve the yield and production efficiency of the twisted brush heads.

[0072] For further details, please see Figures 4-6 The second conveying assembly 12 has a cutting mechanism 121 on the side opposite to the first conveying assembly 11. The cutting mechanism 121 includes an annular cutter 122, which is disposed at one end of a plurality of second through holes 102 opposite to the first conveying assembly 11. The annular cutter 122 can be driven to move radially from a first position to a second position along the plurality of second through holes 102. In one embodiment, the annular cutter 122 is driven to move between the first position and the second position by a driving unit 125.

[0073] When the circular cutter 122 is in the first position (e.g.) Figure 5 As shown, the axes of the multiple second through holes 102 are located within the annular structure of the annular cutter 122. When the annular cutter 122 is in the second position, the axes of the multiple second through holes 102 are located outside the annular structure of the annular cutter 122. The shearing force generated by the annular cutter 122 on the multiple metal wires during its movement from the first position to the second position is used to cut the metal wires.

[0074] In one embodiment, the blade 123 of the annular cutter 122 is located inside the annular structure, and the blade 123 is serrated. The tooth shape (or number of teeth) of the serrated blade 123 matches the cross-section of the first through hole 101.

[0075] In one implementation, such as Figure 6 As shown, the cutting mechanism 121 also includes a mounting base 124, and the annular cutter 122 is mounted on one side of the second conveying assembly 12 via the mounting base 124. The mounting base 124 is provided with small holes for the metal wire to pass through.

[0076] In one implementation, such as Figure 7 As shown, the wire clamping mechanism 130 includes a clamping part 131, an elastic element (not shown in the figure), and a sleeve 132.

[0077] The clamping part 131 is trumpet-shaped and includes a first clamping flap 1311 and a second clamping flap 1312. An elastic member (not shown in the figure) is disposed between the first clamping flap 1311 and the second clamping flap 1312. The first clamping flap 1311 and the second clamping flap 1312 can open or close under the action of external force.

[0078] The sleeve 132 is sleeved on the outer wall of the clamping part 131 and can move between the clamping position and the non-clamping position along the extending direction of the clamping part 131.

[0079] When the sleeve 132 is in the clamping position, the first clamping flap 1311 and the second clamping flap 1312 are squeezed and closed by the sleeve, and multiple metal wires are clamped between the first clamping flap 1311 and the second clamping flap 1312.

[0080] When sleeve 132 is in the non-clamped position (e.g.) Figure 7 As shown, the first clamping flap 1311 and the second clamping flap 1312 extend outside the sleeve 132, and the elastic member resets the first clamping flap 1311 and the second clamping flap 1312 to the open state.

[0081] This utility model embodiment uses the above-described structure to clamp the metal wire, which has a stable and firm clamping force, effectively preventing the metal wire from falling off during the twisting process, and further improving the yield and production efficiency of the twisted brush head.

[0082] In one embodiment, the wire clamping mechanism 130 may also be driven to move toward or away from the second conveying assembly 12, which can provide tension-assisted wire conveying.

[0083] Furthermore, in one implementation, such as Figure 8 As shown, the automatic brush head production device 1 also includes a first bracket 141 and a second bracket 142. The first bracket 141 and the second bracket 142 are located on both sides of the brush bristle clamping mechanism 140 along the first direction, and can be driven to move toward or away from the second conveying assembly 12. Both the first bracket 141 and the second bracket 142 have a toothed structure. The first bracket 141 and the second bracket 142 are used to be inserted between multiple metals to support at least one gap.

[0084] The present invention does not limit the number of teeth of the first bracket 141 and the second bracket 142, and can set them as needed according to the number of metal wires. In one embodiment, the number of metal wires is four, and the number of teeth of the first bracket 141 and the second bracket 142 is two each, with the upper teeth and the lower teeth distributed up and down along the direction of gravity.

[0085] This embodiment of the utility model supports the gaps between multiple metal wires by using the first bracket 141 and the second bracket 142, which can avoid the problem that multiple metal wires are stuck together due to their own weight, making it difficult to insert the brush filaments. This improves the accuracy and efficiency of brush filament insertion, and further improves the yield and production efficiency of twisted brush heads.

[0086] In one implementation, please refer to Figure 9 The automatic production device for twisted brush heads also includes a filament feeding assembly 15, which is located on the second side of the first conveying assembly 11 along the second direction L2. The filament feeding assembly 15 includes a feeding table 151 and a filament cutting blade 152.

[0087] The feeding platform 151 has a first feeding hole 1511 and a second feeding hole 1512 distributed along the direction of gravity. The first feeding hole 1511 and the second feeding hole 1512 penetrate the first and second sidewalls opposite to each other of the feeding platform 151. The bristle cutter 152 is located at the outlet end of the first feeding hole 1511 and the second feeding hole 1512. The bristle cutter 152 can move from a non-cutting position to a cutting position along the direction of gravity. In one embodiment, the bristle cutter 152 has a sheet-like structure.

[0088] Non-cutting areas (e.g.) Figure 9 As shown, the brush filament cutter 152 is suspended above the first feeding hole 1511 and the second feeding hole 1512, and the cutting position is configured such that the brush filament cutter 152 blocks the outlet end of the first feeding hole 1511 and the second feeding hole 1512.

[0089] In one embodiment, the bristle cutter 152 is driven by a drive unit 153 to move between a cutting position and a non-cutting position.

[0090] The present invention, through the above-described structure, enables automatic feeding and cutting of brush filaments, further improving the automation level and production efficiency of the automatic production device for twisted brush heads.

[0091] For further details, please see Figure 10 See also Figure 1 and Figure 9 Understandably, in one embodiment, the automatic brush head production device 1 further includes a bristle transport assembly 16, which includes a base 161 and a bristle clamp 162. The base 161 can be driven to move toward or away from the bristle feeding assembly 15. The bristle clamp 162 is rotatably mounted on the base 161 and can be driven to rotate about a rotation axis. The rotation axis is perpendicular to a first direction L1 and is located in a different plane from the first direction L1. The bristle clamp 162 is used to clamp the bristles located in the first feeding hole 1511 and the second feeding hole 1512.

[0092] In one embodiment, the bristle clamp 162 includes a first clamping plate 1621 and a second clamping plate 1622. The first clamping plate 1621 and the second clamping plate 1622 are arranged opposite to each other and can move towards or away from each other under the action of an external force. Both the first clamping plate 1621 and the second clamping plate 1622 are T-shaped. In one embodiment, the movement of the base 161 toward the bristle feeding assembly 15 is driven by a drive unit 164, and the relative movement of the first clamping plate 1621 and the second clamping plate 1622 is driven by a drive unit 163.

[0093] For further implementation methods, please refer to Figure 11 The automatic production device for twisted brush heads also includes a wire straightening assembly 17. The wire straightening assembly 17 includes multiple straightening shafts, such as a first straightening shaft 171, a second straightening shaft 172, a third straightening shaft 173, and a fourth straightening shaft 174. In one embodiment, the first straightening shaft 171, the second straightening shaft 172, the third straightening shaft 173, and the fourth straightening shaft 174 are arranged in a rhomboid pattern; in other alternative embodiments, they may be arranged in a rectangular pattern. Each straightening shaft is capable of rotating about its own axis under external force. The multiple straightening shafts extend along a first direction, with each pair of straightening shafts arranged adjacent to each other, and multiple wires passing through the gaps between the multiple straightening shafts.

[0094] For an example of the working process, please refer to Figure 1 The metal wire is straightened by the metal wire straightening assembly 17, and then conveyed forward by the first conveying assembly 11 and the second conveying assembly 12. One end of the metal wire is clamped by the metal wire clamping mechanism 130, which provides tension to assist the conveying of the metal wire. Then, the metal wire is spread into the required gap by the first bracket 141 and the second bracket 142, waiting for the brush filaments to be assembled.

[0095] The brush bristles are stretched to the required length by the brush bristle feeding assembly 15 and the brush bristle transport assembly 16, and then cut by the brush bristle cutter 152. The brush bristle transport assembly 16 transfers the brush bristles to the brush bristle assembly assembly 14, which clamps the brush bristles and assembles them into the open gap. Then, the metal wire and brush bristles are twisted together by the twisting assembly 13. Finally, the twisted brush head is cut by the cutting mechanism 121.
