Description

Technical Field

[0001] This utility model relates to the field of bead-making machine technology, specifically a high-speed bead feeder for bead-making machines. Background Technology

[0002] The bead feeder of a beading machine, also known as a bead die, is used to receive the beads fed by the bead feeding mechanism and, together with the bead punching mechanism, punches the beads out and attaches them to the garment fabric.

[0003] In existing technologies, most bead feeding mechanisms are connected to bead feeders through pipes. The beads rely on their own weight to slide down the pipes into the bead feeder, and then a cylinder pushes the beads to the position that cooperates with the punching mechanism. Due to the limitations of the cylinder stroke and operating frequency, the output of beads per minute is less than 300, which cannot meet the needs of high-speed beading.

[0004] Therefore, there is an urgent need for a high-speed bead feeder solution that supports the requirements of high-speed bead threading. Utility Model Content

[0005] The present invention aims to meet the above-mentioned needs of the prior art and provides a high-speed bead feeder for a bead-pinning machine, the technical solution of which is as follows.

[0006] A high-speed bead feeder for a bead-attaching machine includes a mold base. The front section of the mold base has a vertically penetrating bead-punching port on its top surface. The bottom surface of the mold base has a tilting plate that can be flipped down. The mold base also has an elastic return device for driving the tilting plate to return to its original position after flipping down. After the tilting plate returns to its original position, it is used to block the lower end of the bead-punching port. The side of the mold base has a horizontal bead inlet that enters the side of the bead-punching port. The side of the mold base also has an air inlet that communicates with the side of the bead inlet that faces the bead-punching port. The axial direction of the air inlet and the bead inlet forms an acute angle with the vertex facing the bead-punching port. The top surface of the mold base also has an air outlet that vertically enters the intersection of the air inlet and the bead inlet.

[0007] As an improvement, the axial angle between the air inlet and the ball inlet is 30-45 degrees.

[0008] As an improvement, the projection of the inner end opening of the air inlet along the axial direction is located in the inner wall of the inlet.

[0009] As an improvement, the opening area of ​​the air outlet is larger than the opening area of ​​the air inlet.

[0010] As an improvement, the air outlet includes two or more channels arranged axially along the inlet of the bead.

[0011] As an improvement, the rear end of the rocker is pivotally connected to the mold base.

[0012] Furthermore, the side wall of the mold base is provided with a horizontal rotating shaft for cooperating with the rocker. The rear end of the rocker is provided with a rotatable bracket that passes through the horizontal rotating shaft on the top surface. The elastic return device is a torsion spring that passes through the horizontal rotating shaft. One end of the torsion spring elastically abuts against the side wall of the mold base, and the other end of the torsion spring elastically abuts against the top surface of the rocker.

[0013] Compared with the prior art, this utility model has the following beneficial effects: the beads output by the bead feeding mechanism enter the bead inlet through the pipe, and the air inlet is connected to a high-pressure air source. The high-pressure air source releases through the path of the air inlet-air outlet to form a high-speed airflow. On the one hand, the high-pressure airflow can directly push the beads located at the intersection of the bead inlet and the air inlet into the bead-punching port quickly. On the other hand, the high-speed airflow can be used to generate a negative pressure at the outer end of the bead inlet. The beads that subsequently enter the bead inlet can be accelerated into the intersection of the bead inlet and the air inlet due to the negative pressure suction. The number of beads output to the bead-punching port per minute is as high as 300-600, which meets the needs of high-speed bead-punching.

[0014] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0022] Please see Figures 1 to 2As shown, in one embodiment, this utility model provides a high-speed bead feeder for a bead-pinning machine. Its structure includes a mold base 1. The front section of the mold base 1 has a vertically penetrating bead-punching port 2 on its top surface. The bottom surface of the mold base 1 has a tilting plate 3 that can be flipped down. The mold base 1 also has an elastic return device 4 for driving the tilting plate 3 to tilt down and then return to its original position. After the tilting plate 3 returns to its original position, it is used to seal the lower end of the bead-punching port 2. A horizontal bead inlet 5 is opened on the side of the mold base 1, leading into the side of the bead-punching port 2. An air inlet 6 is also opened on the side of the mold base 1, communicating with the side of the bead inlet 5 facing the bead-punching port 2. The axial direction of the air inlet and the bead inlet 5 forms an acute angle with its apex facing the bead-punching port 2. An air outlet 7 is also opened on the top surface of the mold base 1, vertically leading into the intersection of the air inlet and the bead inlet 5.

[0023] In the above embodiment, the beads output by the bead feeding mechanism enter the bead inlet 5 through a pipe, and the air inlet 6 is connected to a high-pressure air source.

[0024] Combined Figure 3 As shown, the beads 100 output by the bead feeding mechanism enter the bead inlet 5 through the pipe and arrive in a queue at the intersection of the bead inlet 5 and the air inlet 6. Given that the mold base 1 in the above embodiment has an air inlet 6 on its side that communicates with the side of the bead inlet 5 facing the punching port 2, and the top surface of the mold base 1 also has an air outlet 7 vertically connected to the intersection of the air inlet and the bead inlet 5, the high-pressure air source can be released through the path of the air inlet 6 and the air outlet 7, forming a high-speed airflow. Furthermore, because the axial direction of the air inlet and the bead inlet 5 forms an acute angle with its apex facing the punching port 2, the high-pressure airflow can directly and quickly push the beads 101 located at the intersection of the bead inlet 5 and the air inlet 6 into the punching port 2. Also, because the high-speed airflow creates a negative pressure at the outer end of the bead inlet 5, the beads 102 subsequently entering the bead inlet 5 are accelerated into the intersection of the bead inlet 5 and the air inlet 6 due to the negative pressure suction.

[0025] In the above embodiment, the arrangement of the air outlet 7 limits the main path of the high-speed airflow to the air inlet 6 to the air outlet 7, and also provides a pressure relief path for the high-speed airflow, preventing it from flowing back from the bead inlet 5 to the pipe of the bead delivery mechanism, thus preventing the beads in the bead inlet 5 from flowing back into the pipe of the bead delivery mechanism.

[0026] Combined Figure 5 As shown, in the above embodiment, the bead 101 entering the punching port 2 rests on the rocker plate 3. According to the conventional setup in the art, the punch 103 of the punching mechanism punches downward through the punching port 2, and the rocker plate 3 flips downward under the action of the bead 101 in the punching port 2, so that the bead 101 is punched out of the punching port 2 and nailed to the garment fabric under the action of the punch 103. After the punch 103 resets, the rocker plate 3 also flips upward and resets under the action of the elastic recovery device 4, waiting for the next bead to enter the punching port 2 from the bead inlet 5.

[0027] Based on the above principles, the high-speed bead feeder for bead-attaching machines using the above-described implementation method significantly improves the speed at which beads are output to the bead-attaching opening. During the testing phase, the high-speed bead feeder for bead-attaching machines using the above-described implementation method outputs far more than 150 beads per minute to the bead-attaching opening, meeting the requirements for high-speed bead-attaching.

[0028] In the above embodiments, preferably, the high-speed airflow formed by the release of high-pressure gas source is set to high-frequency on / off, and its on / off frequency is adapted to the expected bead delivery frequency, that is, one bead is delivered for each release of high-pressure gas source, which can significantly reduce energy consumption.

[0029] In a preferred embodiment, such as Figure 2 and Figure 3 As shown, the axial angle between the air inlet 6 and the bead inlet 5 is 30-45 degrees. The high-speed airflow generates a more ideal thrust on the bead located at the intersection of the bead inlet 5 and the air inlet 6, which can quickly push the bead into the bead outlet 2.

[0030] In another preferred embodiment, such as Figure 2 and Figure 3 As shown, the projection of the inner end opening of the air inlet 6 along the axial direction is located in the inner wall of the bead inlet 5, so that the high-speed airflow will not directly impact the bead outlet 2, which effectively avoids the beads entering the bead outlet 2 from moving along the axial direction of the bead outlet 2 under the impact of the high-speed airflow.

[0031] In another preferred embodiment, such as Figure 1 As shown, the opening area of ​​the air outlet 7 is larger than that of the air inlet 6, which allows for more effective decompression and exhaust of the high-speed airflow. Preferably, the air outlet 7 includes two or more channels arranged along the axial direction of the bead inlet 5, which increases the opening area of ​​the air outlet 7 by diverting the flow and also makes more effective use of the gap between the beads in the bead inlet for exhaust.

[0032] In another preferred embodiment, such as Figure 4 As shown, the rear end of the rocker 3 is pivotally connected to the mold base 1. Furthermore, the side wall of the mold base 1 is provided with a horizontal rotating shaft 11 for cooperating with the rocker 3. The rear end of the rocker 3 is provided with a rotatable bracket 31 that passes through the horizontal rotating shaft 11. The elastic return device 4 is a torsion spring that passes through the horizontal rotating shaft 11. One end of the torsion spring elastically abuts against the side wall of the mold base 1, and the other end of the torsion spring elastically abuts against the top surface of the rocker 3.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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.
