Feeding mechanism of sequin chip mounter

Abstract

The utility model discloses a feeding mechanism of a sequin chip mounter. The feeding mechanism comprises a mounting part, a mounting shaft, a limiting cap, a motor, an inching switch and an extension part. The sequins led out of the winding drum downwards penetrate through the penetrating-out groove and are fed into the sequin chip mounter. When the sequins are used by the chip mounter, the sequins gradually approach and contact the inner wall of the penetrating groove, and finally, under the action of friction force, the movable contact of the inching switch is driven to move downwards to contact the fixed contact, the inching switch is connected, the motor is made to rotate, the mounting shaft and the winding drum on the mounting shaft are driven to rotate, and the sequins are sent out. Along with sending out of the sequins, the sequins are gradually separated from the inner wall of the penetrating groove, the movable contact of the inching switch is reset to be disconnected with the fixed contact, and the motor stops rotating. The process is circulated, and the segment of sequins led out of the winding drum and fed into the sequin chip mounter is dynamically kept within a proper range. The feeding device has the beneficial effects that the sequins are fed into the sequin chip mounter more smoothly, the conditions of clamping and breakage are reduced, and the efficiency is improved.

Description

Technical Field

[0001] The utility model relates to clothing processing, in particular to a feeding mechanism of a bead patch machine. Background Art

[0002] In clothing processing, in order to improve the beauty and design of clothing, sometimes designed patterns are made on clothing. Sequins are also one of the materials used to make patterns, that is, through a sequin mounting machine, the sequins are connected to the corresponding positions of the clothing in sequence according to the shape of the imported pattern to form the imported pattern. Sequins are generally connected together and then wound on a reel. First, the reel is connected to the corresponding position of the sequin mounting machine, generally a rotating shaft for the reel to be installed, and then the sequins are led out of the reel and fed into the sequin mounting machine, and the sequins are pulled out of the reel by the sequin mounting machine. There are still some problems: in the process of the sequin mounting machine pulling the sequins out of the reel, it is easy to get stuck or break, and it is necessary to manually pause the sequin mounting machine in time and perform corresponding repair operations, which affects the processing efficiency.

[0035] See also Figure 1 and Figure 2 A feeding mechanism of a bead chip placement machine includes a mounting portion 1, a mounting shaft 2, a limit cap 3, a motor 4, a momentary switch 5 and an extension portion 6.

[0036] The mounting portion 1 is used to mount the remaining components and to mount the feeding mechanism to the bead placement machine. More specifically, the lower side of the mounting portion 1 may have a bent portion 1a, which is used to be fixedly connected to the bead placement machine. Relative to the bent portion 1a, the upper side of the mounting portion 1 is inclined, with an upper mounting position and a middle mounting position.

[0037] The first end of the mounting shaft 2 is rotatably connected to the upper mounting position of the mounting portion 1 , and the mounting shaft 2 may be directly rotatably connected to the mounting portion 1 via a bearing.

[0038] See also Figure 2 and Figure 3 The limiting cap 3 is detachably connected to the second end of the mounting shaft 2. Through the cooperation between the limiting cap 3 and the mounting shaft 2, the reel 7 wound with the beads 7a is fixed on the mounting shaft 2. More specifically, a stopper 2a can be fixedly connected to the mounting shaft 2, and the stopper 2a and the limiting cap 3 are respectively pressed against the two sides of the reel 7 to press and fix the reel 7.

[0039] In some embodiments, the position near the second end of the installation shaft 2 is a threaded rod 2b for threading the limit cap 3. That is, the limit cap 3 and the installation shaft 2 are detachably connected by threads, which is simple and convenient to operate, and a hand-tightened nut with a plum head can be used as the limit cap 3.

[0040] The motor 4 is used to drive the mounting shaft 2 to rotate.

[0041] See also Figure 3 and Figure 7 In some embodiments, the motor 4 and the mounting shaft 2 are connected via a reducer 8. More specifically, the reducer 8 may include a housing 8a, a meshing gear 8b and a pinion 8c, and a meshing worm wheel 8d and a worm 8e. The mounting shaft 2 is rotationally connected to the housing 8a, and the housing 8a is fixedly connected to the mounting portion 1, that is, the mounting shaft 2 may also be indirectly rotationally connected to the mounting portion 1 through the housing 8a. The mounting shaft 2 is also fixedly connected to the gear 8b, and the pinion 8c and the worm wheel 8d are rotationally connected to the housing 8a through the same shaft. The motor 4 is fixedly connected to the housing 8a, and the output shaft extends into the housing 8a and is fixedly connected to the worm wheel 8d.

[0042] See also Figure 3 and Figure 6 The inching switch 5 is installed at the middle installation position of the installation part 1 to control the motor 4, that is, the inching switch 5 is connected to the control circuit of the motor 4. Specifically, the movable contact 5a of the inching switch 5 can be made of suitable materials and reset to disconnect from the fixed contact 5b by its own elasticity. An elastic member, such as a torsion spring, a compression spring, etc., can also be provided to reset the movable contact 5a to disconnect from the fixed contact 5b.

[0043] One end of the extension part 6 is fixed to the movable contact 5a of the inching switch 5, and the other end is provided with a passing groove 6a for the bead piece 7a to pass through.

[0044] In this way, the bead piece 7a drawn out from the reel 7 passes downward through the outlet slot 6a and is fed into the bead piece placement machine. As the bead piece 7a is used by the placement machine, the bead piece 7a gradually approaches and contacts the inner wall of the outlet slot 6a, and finally, under the action of friction, drives the movable contact 5a of the moment switch 5 to move downward until it contacts the fixed contact 5b, connects the moment switch 5, causes the motor 4 to rotate, drives the mounting shaft 2 and the reel 7 on the mounting shaft 2 to rotate, and delivers the bead piece 7a. As the bead piece 7a is delivered, the bead piece 7a gradually separates from the inner wall of the outlet slot 6a, and the movable contact 5a of the moment switch 5 resets to disconnect from the fixed contact 5b, and the motor 4 stops rotating. In this cycle, the section of the bead piece 7a drawn out from the reel 7 and fed into the bead piece placement machine is dynamically maintained within a suitable range.

[0045] See also Figure 4 In some embodiments, there is a distance between the through slot 6a and the axis of the mounting shaft 2 in the front-to-rear direction.

[0046] In this way, the lead-out position of the bead piece 7a on the reel 7 is close to directly below the axis of the mounting shaft 2, and a spacing is designed between the outlet groove 6a and the axis of the mounting shaft 2 in the front-to-back direction. The section of the bead piece 7a between the reel 7 and the outlet groove 6a is inclined, making it easier to contact the inner wall of the outlet groove 6a.

[0047] See also Figure 5 In some embodiments, the width of the through slot 6a along the axis of the mounting shaft 2 can be adjusted.

[0048] In this way, the penetration groove 6a can adapt to beads 7a of different sizes.

[0049] Further, the extension portion 6 includes a first portion 6b and a second portion 6c. The first end of the first portion 6b is fixed to the contact of the inching switch 5. The second portion 6c is U-shaped and can be adjusted to a fixed position at the second end of the first portion 6b. More specifically, the two sides of the second portion 6c and the first portion 6b can be connected by a cross-shaped connecting sleeve 6c1, and the connection between the second portion 6c and the connecting sleeve 6c1 has a damping.
