Description

Technical Field

[0001] This utility model relates to the field of garment processing equipment, specifically a bead plate assembly for a beading machine. Background Technology

[0002] The applicant proposed a bead plate assembly in Chinese utility model application No. 2025200807194, which effectively solved the problem of wear and tear on beads caused by collision in the hopper.

[0003] Through practice, the applicant discovered that the above technical solution has areas that need further improvement. The U-shaped groove directly connects to the perforation, so the beads piled in the hopper directly enter the rotating component and contact the lever within their stacking height. On the one hand, the higher the bead stacking height in the hopper, the more beads the rear end of the lever will collide with, thus increasing the likelihood of bead wear. On the other hand, the higher the bead stacking height in the hopper, the more beads enter the rotating component, the more beads are driven by the lever, and the more beads fall into the slot of the guide tube, thus increasing the likelihood of beads getting stuck in the slot of the guide tube.

[0004] Admittedly, the likelihood of the above situation occurring can be reduced by lowering the stacking height of the spikes in the hopper. However, lowering the stacking height of the spikes in the hopper will reduce the upper limit of the spike inventory, requiring frequent checks to replenish the spikes in the hopper in a timely manner.

[0005] Therefore, the applicant proposed an iterative solution for the above technical solution. Utility Model Content

[0006] This utility model proposes a bead plate assembly for a bead-pinning machine, which effectively reduces the wear and jamming probability of beads without reducing the upper limit of bead storage in the hopper. The specific technical solution is as follows.

[0007] The bead tray assembly for a bead-pinning machine includes:

[0008] The base has an outer frame, with a front panel and a back panel at the front and rear ends of the outer frame. A circular through hole is provided on the back panel, and a hopper is provided on the rear wall of the back panel. The circular through hole communicates with the front end of the hopper.

[0009] A rotating component is located on the front wall of the back plate. It has a cylindrical outer shell that is connected to and coaxially rotates with a circular through hole. The inner circular surface of the cylindrical outer shell has the same radius as the circular through hole. A plurality of paddles are fixed on the inner circular surface of the cylindrical outer shell, which are evenly distributed in the circumference and extend toward the axis of the cylindrical outer shell. Each paddle is rotationally symmetrical with respect to the axis of the cylindrical outer shell.

[0010] A driving component, mounted on the base, is used to drive the rotating component to rotate;

[0011] The discharge pipe has its rear end inclined upward through the panel into the base, and is provided with a coaxial arc-shaped guide groove; the upper end of the arc-shaped guide groove is open, and the radius of its groove surface is consistent with the diameter of the discharge pipe; and the arc-shaped guide groove extends into the circular through hole, and the end of each pawl facing the axis of the cylindrical shell is close to the arc-shaped guide groove in the radial direction of the cylindrical shell.

[0012] A baffle plate is installed in the hopper. The baffle plate forms a gap between the front end of the hopper and the circular through hole along the axial direction of the circular through hole. The lower edge of the baffle plate is fitted with the bottom of the hopper to form a material channel connecting the hopper and the circular through hole.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The baffle plate forms a barrier between the hopper and the circular through hole. When the hopper is full of nail beads, only a small portion of the nail beads can reach the rear end of the circular through hole through the material channel. The rear end of the paddle can only make limited contact with this small portion of nail beads, so the wear probability of the nail beads is significantly reduced.

[0015] (2) Given that only a small number of nails can reach the rear end of the circular through hole through the material channel, the number of nails entering the cylindrical shell of the rotating part is always kept small. The number of nails driven by the paddle is small, and the number of nails falling into the arc guide groove is also small, thus significantly reducing the probability of nail jamming.

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0020] Explanation of reference numerals in the attached figures:

[0021] Base 1, outer frame 11, panel 12, back plate 13, circular through hole 14, hopper 2, rotating component 3, cylindrical shell 31, paddle 32, driving component 4, discharge pipe 5, arc-shaped guide groove 51, baffle plate 6, material channel 61, external toothed ring 33, motor 41, gear 42, guide wheel 15, guide elbow 7, guide tube 9. Detailed Implementation

[0022] like Figure 1 , Figures 2 to 3 As shown, in one embodiment, the bead plate assembly for the bead-pinning machine includes:

[0023] The base 1 has an outer frame 11, with a front panel 12 and a back panel 13 at the front and rear ends of the outer frame 11 respectively. A circular through hole 14 is provided on the back panel 13, and a hopper 2 is provided on the rear wall of the back panel 13. The circular through hole 14 communicates with the front end of the hopper 2.

[0024] The rotating component 3 is located on the front wall of the back plate 13. It has a cylindrical outer shell 31 that is mated with and coaxially rotated with the circular through hole 14. The inner circular surface of the cylindrical outer shell 31 has the same radius as the circular through hole 14. A plurality of paddles 32 are fixed on the inner circular surface of the cylindrical outer shell 31, which are evenly distributed in the circumference and extend toward the axis of the cylindrical outer shell 31. Each paddle 32 is rotationally symmetrical with respect to the axis of the cylindrical outer shell 31.

[0025] The driving component 4 is mounted on the base 1 and is used to drive the rotating component 3 to rotate.

[0026] The discharge pipe 5, with its rear end inclined upward, passes through the panel 12 and enters the base 1, and is provided with a coaxially connected arc-shaped guide groove 51; the upper end of the arc-shaped guide groove 51 is open, and the radius of its groove surface is consistent with the diameter of the discharge pipe 5; and the arc-shaped guide groove 51 extends into the circular through hole 14, and the ends of each paddle 32 facing the axis of the cylindrical outer shell 31 are close to the arc-shaped guide groove 51 in the radial direction of the cylindrical outer shell 31.

[0027] A baffle plate 6 is provided in the hopper 2. The baffle plate 6 forms a gap between the front end of the hopper 2 and the circular through hole 14 along the axial direction of the circular through hole 14. The lower edge of the baffle plate 6 is fitted with the bottom of the hopper 2 to form a material channel 61 that connects the hopper 2 and the circular through hole 14.

[0028] like Figure 3 As shown, in the above embodiment, the hopper 2 is used to stack the nail beads, and the diameter of the discharge pipe 5 is set to be slightly larger than the nail beads. The nail beads reach the rear end of the circular through hole 14 through the material channel 61, and then enter the cylindrical shell 31 of the rotating component 3. When the rotating component 3 is driven to rotate by the driving component 4, the nail beads located in the gap of the paddle 32 will be carried up by the paddle 32 until the paddle 32 changes its posture with the rotation of the rotating component, causing the nail beads to roll off the paddle 32; and since the end of the paddle 32 facing the axis of the cylindrical shell 31 is close to the arc-shaped guide groove 51 in the radial direction of the cylindrical shell 31, most of the nail beads that roll off the paddle 32 will fall into the arc-shaped guide groove 51, and then be sent out through the arc-shaped guide groove 51 and the discharge pipe 5, and slide through the guide tube 9 to the nailing mechanism of the nailing machine.

[0029] In the above embodiment, the baffle plate 6 forms a barrier between the hopper 2 and the circular through hole 14. When the hopper 2 is fully loaded with nail beads, only a small portion of the nail beads can reach the rear end of the circular through hole 14 through the material channel 61. The rear end of the paddle 32 can only make limited contact with this small portion of nail beads, thus significantly reducing the wear probability of the nail beads.

[0030] Meanwhile, since only a small number of beads can reach the rear end of the circular through hole 14 through the material channel 61, the number of beads entering the cylindrical outer shell 31 of the rotating part 3 remains small. The number of beads driven by the paddle 32 is small, and the number of beads falling into the arc-shaped guide groove 51 is also correspondingly small, significantly reducing the probability of beads getting stuck.

[0031] In a preferred embodiment, the inner bottom of the hopper 2 is formed into an arc shape with the same diameter as the circular through hole 14. Furthermore, since the inner surface of the cylindrical outer shell 31 has the same radius as the circular through hole 14, the inner bottom of the hopper 2, the circular through hole 14, and the cylindrical outer shell 31 are perfectly aligned without any dead angles, allowing the beads at the bottom of the hopper 2 to enter the cylindrical outer shell 31 more smoothly through the circular through hole 14.

[0032] In another preferred embodiment, the inner bottom of the hopper 2 is inclined to be lower in the front and higher in the back, and the rear end of the inner bottom of the hopper 2 is lower than the upper edge of the material channel 61. This arrangement is more conducive to the beads at the bottom of the hopper 2 entering the cylindrical outer shell 31.

[0033] In another preferred embodiment, an external gear ring 33 is coaxially fixed on the outer circular surface of the cylindrical shell 31. The driving component 4 includes a motor 41 fixed on the base 1. The rotating shaft of the motor 41 is perpendicular to the back plate 13, and a gear 42 is fixed on the rotating shaft of the motor 41. The gear 42 meshes with the external gear ring 33 to form a transmission engagement.

[0034] Furthermore, the motor 41 is fixed to the rear wall of the back plate 13, the shaft of the motor 41 passes through to the front end of the back plate 13, and the gear 42 is connected to the shaft of the motor 41 from the front end of the back plate 13.

[0035] Furthermore, the front wall of the back plate 13 is provided with at least four guide wheels 15 circumferentially spaced in the circular through holes 14. The guide wheels 15 are located at the front end of the outer toothed ring 33 and respectively abut against the outer circular surface of the cylindrical shell 31 with their edges forming a circular-on-circular fit. Among them, at least two guide wheels 15 are distributed on the left and right sides of the lower part of the outer circular surface of the cylindrical shell 31, which can better support the cylindrical shell 31. With the cooperation of the guide wheels 15, the axis of the cylindrical shell 31 is kept stable, and the rotation is smoother.

[0036] In another preferred embodiment, the paddle 32 is curved in an arc shape, so that the bead can rise to a higher position as the rotating member 3 rotates, making it easier for it to fall onto the arc-shaped guide groove 51.

[0037] In an improved embodiment, the bead plate assembly for the bead-pinning machine of this invention further includes a guide elbow 7 connected to the front end of the discharge pipe 5. The guide elbow 7 has a guide channel with the same diameter as the discharge pipe 5 inside. The first end of the guide channel is coaxially connected to the front end of the discharge pipe 5, and the other end is bent downwards to be axially vertical. With the cooperation of the guide elbow 7, the beads delivered by the discharge pipe 5 will be discharged vertically downwards, and their movement in the connected guide tube 9 will be smoother.

[0038] Although embodiments of the present invention have been shown and described, those skilled in the art will recognize that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
