Description

Technical Field

[0001] This utility model relates to the field of paintbrush manufacturing technology, specifically to a high-speed rotary vertical feeding mechanism for paintbrush processing. Background Technology

[0002] The main structure of an art brush or makeup brush consists of a handle and a head. The head includes a metal sleeve and bristles (brush bristles for paintbrushes and brush bristles for makeup brushes). Taking a paintbrush as an example, the metal sleeve is shaped like a straight tube or a tapered tube, and the bristles are fixed inside the metal sleeve and extend a certain length from one end.

[0003] During the production of brushes with brush bristles, the brush shell and brush bristles are fed separately, and the brush bristles are inserted into the brush shell by a feeding mechanism. However, the existing feeding mechanism usually adopts a flipping type, that is, after picking up the material from the picking table, it rises and flips to the feeding position, then falls down, and returns along the same path after the feeding is completed. In other words, the feeding mechanism needs to perform lifting and rotating actions separately, which prolongs the feeding time. Moreover, multiple devices work together to perform feeding, which requires high precision control of each device. Utility Model Content

The pneumatic gripper has a first stroke and a second stroke; in the first stroke, the pneumatic gripper rotates around the first rotating rod; in the second stroke, the pneumatic gripper performs a vertical movement.

[0007] Furthermore, the limiting unit includes a second rotating shaft rotatably connected to the sliding seat, the pneumatic gripper fixedly connected to the second rotating shaft, one end of the second rotating shaft passing through the sliding seat and fixedly connected to a fixing plate, two limiting wheels rotatably arranged on the fixing plate, and two limiting rods fixedly arranged on the frame respectively. When both limiting wheels abut against the limiting rods, the pneumatic gripper remains in a horizontal state, and multiple compression springs are arranged between the fixing seat and the sliding seat.

[0008] Further, the two limiting rods are vertically arranged, and a line connecting the centers of the two limiting wheels is perpendicular to a plane on which the clamping jaws of the pneumatic clamping jaw are located.

[0009] Further, a plurality of openings are formed on a side of the fixing seat facing the sliding seat, and each compression spring is arranged in a corresponding opening.

[0010] Further, a bolt is threadedly connected to the sliding seat, and an end of the bolt extends into the limiting hole of the fixing seat.

[0011] Further, a torsion spring is arranged between the second rotating shaft and the sliding seat.

Obviously, the described embodiments are part of the embodiments of the present disclosure, not all. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative labor belong to the scope of protection of the present disclosure.

[0024] Please refer to Figures 1-4 A high-speed rotary vertical feeding mechanism for brush processing, comprising a rack 1, a feeding assembly 2 is arranged on the rack 1, the feeding assembly 2 comprises a driving motor 21 fixedly arranged on the rack 1, a first rotating rod 22 is fixedly connected to the output shaft of the driving motor 21, the first rotating rod 22 is rotationally connected to the rack 1, a fixed seat 23 is fixedly connected to the first rotating rod 22, a sliding seat 24 is slidingly connected to the fixed seat 23, a limiting unit 3 is arranged on the sliding seat 24, a pneumatic clamping jaw 31 is arranged on the limiting unit 3, the pneumatic clamping jaw 31 has a first stroke and a second stroke; in the first stroke, the pneumatic clamping jaw 31 rotates around the first rotating rod 22; in the second stroke, the pneumatic clamping jaw 31 moves vertically.

[0025] Further, the limiting unit 3 comprises a second rotating shaft 32 rotationally connected to the sliding seat 24, the pneumatic clamping jaw 31 is fixedly connected to the second rotating shaft 32, one end of the second rotating shaft 32 penetrates through the sliding seat 24 and is fixedly connected with a fixed plate 33, two limiting wheels 34 are rotationally arranged on the fixed plate 33, two limiting rods 35 are fixedly arranged on the rack 1 respectively, when the two limiting wheels 34 abut against the limiting rods 35, the pneumatic clamping jaw 31 keeps a horizontal state, a plurality of compression springs 36 are arranged between the fixed seat 23 and the sliding seat 24. The compression springs 36 are used to move the sliding seat 24 away from the first rotating rod 22.

[0026] The driving motor 21 drives the first rotating rod 22 to rotate, the first rotating rod 22 drives the fixed seat 23 to rotate, the fixed seat 23 drives the sliding seat 24 to rotate, the sliding seat 24 drives the pneumatic clamping jaw 31 and the fixed plate 33 to rotate around the first rotating rod 22 through the second rotating shaft 32, that is, the pneumatic clamping jaw 31 performs the first stroke; when one limiting wheel 34 on the fixed plate 33 abuts against the limiting rod 35, the first rotating rod 22 continues to rotate, and since the limiting wheel 34 is limited by the limiting rod 35, the sliding seat 24 slides along the fixed seat 23 to the first rotating rod 22 and compresses the compression spring 36, at this time, the second rotating shaft 32 also rotates; when two limiting wheels 34 on the fixed plate 33 abut against the limiting rod 35, the first rotating rod 22 continues to rotate, and since the two limiting wheels 34 are limited by the limiting rod 35, at this time, the rotation of the sliding seat 24 makes the two limiting wheels 34 move along the limiting rod 35 (that is, the two limiting wheels 34 move vertically), the movement of the two limiting wheels 34 drives the pneumatic clamping jaw 31 to move synchronously through the fixed plate 33 and the second rotating shaft 32, that is, at this time, the pneumatic clamping jaw 31 performs the second stroke, so as to place the brush in the inside of the pen barrel. The process of the pneumatic clamping jaw 31 clamping the brush is the same as the principle of the pneumatic clamping jaw 31 placing the brush, which will not be repeated here.

[0027] Further, the two limiting rods 35 are vertically arranged, and the line connecting the centers of the two limiting wheels 34 is perpendicular to the plane where the clamping jaws of the pneumatic clamping jaw 31 are located. So that when the two limiting wheels 34 move along the limiting rod 35, the pneumatic clamping jaw 31 remains in a horizontal state, so as to vertically place the brush into the inside of the pen barrel.

[0028] Further, a plurality of openings 37 are formed on the side of the fixed seat 23 facing the sliding seat 24, and each compression spring 36 is arranged in a corresponding opening 37. The two ends of the compression spring 36 are fixedly connected with the sliding seat 24 and the side wall of the opening 37, respectively.

[0029] Further, a threaded bolt 38 is threadedly connected to the sliding seat 24, and the end of the threaded bolt 38 extends into a limiting hole 39 on the fixed seat 23. The cooperation of the threaded bolt 38 and the limiting hole 39 can limit the excessive movement of the sliding seat 24 along the fixed seat 23 away from the first rotating rod 22, in other words, prevent the sliding seat 24 from being separated from the fixed seat 23.

[0030] Further, a torsion spring (not shown in the figure) is arranged between the second rotating shaft 32 and the sliding seat 24. In order to prevent the second rotating shaft 32 from being deflected and colliding with the sliding seat 24 under the action of gravity when the pneumatic clamping jaw 31 performs the first stroke.

[0031] The pneumatic clamping jaw 31 is prior art, two output blocks are driven by a cylinder to move towards or away from each other, and clamping jaws are arranged on the two output blocks respectively, so as to clamp the brush hair, and the person skilled in the art can realize the function without creative labor. The two clamping jaws of the pneumatic clamping jaw 31 in the application can be arranged in an arc shape, and corresponding sliding grooves and sliding blocks are arranged on the side of the two clamping jaws close to each other, so that the two clamping jaws can clamp the brush hair when they are close to each other.

[0032] The above only describes some exemplary embodiments of the present application by way of illustration, without doubt, for the person skilled in the art, without departing from the spirit and scope of the present application, the described embodiments can be modified in various ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present application.
