Description

Technical Field

[0001] This utility model relates to the field of sealing edible mushroom bags, specifically an automatic sealing and fastening device. Background Technology

[0002] Sealing machines are widely used for sealing and packaging edible mushroom bags. The fasteners are fed into the bag opening by a fastener feeder, and a motor-driven hinge pushes the fasteners onto the bottom film as the bag closes, thus sealing the bag. Current equipment typically uses a fastener frame mounted on the top of the panel, where fasteners fall freely to achieve the fastening purpose. However, this feeding method lacks external propulsion, so even slight resistance during the fastener's descent can cause the entire fastener strip to jam, interrupting the sealing process and affecting efficiency. Furthermore, this feeding method cannot control the amount of fasteners fed; it's not uncommon for two or three fasteners to be attached to a single bag, wasting materials and increasing production costs. Utility Model Content

[0003] The purpose of this invention is to provide an automatic buckle feeding device that is simple in structure, easy to operate, and has a good buckle feeding effect, so as to overcome the problems existing in the existing equipment.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic buckle feeding device, including a frame, a material tray, a material passage, guide wheels, and a buckle pushing mechanism. The buckle pushing mechanism includes a roller assembly capable of driving the buckle forward and a drive assembly for driving the roller assembly to rotate. The roller assembly includes a rotating shaft rotatably connected to the frame and a roller fixedly sleeved on one end of the rotating shaft. The drive assembly includes a driven sprocket sleeved on the other end of the rotating shaft, a chain wound around the driven sprocket, a drive motor mounted on the frame, and a main sprocket mounted on the drive motor and connected to one end of the chain. A one-way bearing is sleeved on the other end of the rotating shaft.

[0005] Based on the above technical solution, the present invention can be further improved as follows: As a further improvement to the above technical solution, the material tray is located at one end near the material passage, the guide wheel is connected to the other end of the material passage, and the guide wheel is fixedly mounted on the frame. The roller is located above the guide wheel and the material passage, and a gap is formed between the roller and the guide wheel for the fastener to pass through.

[0006] As a further improvement to the above technical solution, a rotating shaft is installed on the frame, the material tray is sleeved on the rotating shaft, and a fastening strip is wound on the material tray, the fastening strip including a plurality of fastenings connected in sequence.

[0007] As a further improvement to the above technical solution, the fastener is U-shaped. When the roller pushes the fastener strip on the tray, the roller enters from the U-shaped opening of the fastener, and the two ends of the U-shaped fastener clamp the outer edge of the roller.

[0008] As a further improvement to the above technical solution, the drive assembly also includes a spring, one end of which is connected to the frame and the other end of which is connected to the other end of the chain.

[0009] The beneficial effects of this utility model are as follows: This utility model drives the roller connected to the rotating shaft to rotate through the drive component. Due to the roller drive, even with some resistance, the fastener can move down smoothly, reducing the risk of the fastener strip getting stuck. The one-way bearing on the rotating shaft ensures that the roller can only push the fastener forward and not backward. The drive motor drives the main sprocket to rotate counterclockwise by a preset angle, which can only push one fastener forward and then immediately return to the original position. This can avoid the waste of raw materials caused by multiple fasteners being fed at the same time, making the operation more convenient and improving the fastener feeding efficiency.

[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0015] like Figure 1 , Figure 2 and Figure 3 As shown, a preferred embodiment of this utility model provides an automatic buckle feeding device, including a frame 1, a material tray 2, a material passage 3, a guide wheel 4, and a buckle pushing mechanism. The buckle pushing mechanism includes a roller assembly 51 capable of driving the buckle 211 forward and a driving assembly 52 driving the roller assembly 51 to rotate. The roller assembly 51 includes a rotating shaft 511 rotatably connected to the frame 1 and a roller 512 fixedly sleeved on one end of the rotating shaft 511. The driving assembly 52 includes a driven sprocket 525 sleeved on the other end of the rotating shaft 511. A chain 523 is wound around a sprocket 525, a drive motor 521 is mounted on a frame 1, and a main sprocket 522 is mounted on the drive motor 521 and connected to one end of the chain 523. A one-way bearing 513 is sleeved on the other end of the shaft 511. A material tray 2 is located near one end of the material passage 3, and a guide wheel 4 is connected to the other end of the material passage 3. The guide wheel 4 is fixedly mounted on the frame 1. A roller 512 is located above the guide wheel 4 and the material passage 3, and a gap is formed between the roller 512 and the guide wheel 4 for the fastener 211 to pass through.

[0016] Specifically, in this embodiment, a rotating shaft 11 is mounted on the frame 1, and the material tray 2 is sleeved on the rotating shaft 11. A fastening strip 21 is wound around the material tray 2, and the fastening strip 21 includes a plurality of sequentially connected fasteners 211 (similar to staples). Preferably, the drive assembly 52 further includes a spring 524, one end of which is connected to the frame 1, and the other end of which is connected to the other end of the chain 523.

[0017] The one-way bearing 513 is a type of bearing that can rotate freely in one direction and is locked in the other. When the drive motor 521 drives the main sprocket 522 to reset, that is, drives the main sprocket 522 to rotate clockwise, it drives the chain 523 and the driven sprocket 525 to rotate back to their original positions. At this time, since the one-way bearing 513 is provided between the driven sprocket 525 and the shaft 511, when the driven sprocket 525 rotates in the opposite direction (clockwise), the shaft 511 and the roller 512 connected to the shaft 511 do not rotate.

[0018] The drive motor 521 drives the main sprocket 522 to rotate counterclockwise by a preset angle, which drives the chain 523 and the driven sprocket 525 to rotate synchronously. In turn, the rotation of the sprocket 525 drives the rotating shaft 511 and the roller 512 connected to the rotating shaft 511 to rotate. The roller 512 pushes the fastener strip 21 on the material tray 2 to move along the material passage 3. The fastener strip 21 that walks out of the material passage 3 enters the gap between the roller 512 and the guide wheel 4 and moves down to wrap around the guide wheel 4.

[0019] In this embodiment, the fastener 211 is arranged in a U-shape. When the roller 512 pushes the fastener strip 21 on the tray 2, the roller 512 enters from the U-shaped opening of the fastener 211, and the two ends of the U-shaped fastener 211 clamp the outer edge of the roller 512.

[0020] In operation, this invention first pulls down the fastener strip 21 on the material tray 2, then pries the roller 512 outward. After the fastener strip 21 enters the material passage 3, the roller 512 is released. At this time, the roller 512 and the guide wheel 4 will tightly clamp the fastener strip 21. When it is necessary to release the fastener, the drive motor 521 drives the main sprocket 522 to rotate counterclockwise by a preset angle, driving the chain 523 and the driven sprocket 525 to rotate synchronously. The rotation of the driven sprocket 525 then drives the rotating shaft 511 and the roller 512 connected to the rotating shaft 511 to rotate by a set angle each time. Thus, the roller 512 can only rotate by the set angle once per rotation. Push one pin 211 down; then drive motor 521 drives main sprocket 522 to reset, that is, drive main sprocket 522 to rotate clockwise by a preset angle, driving chain 523 and driven sprocket 525 to rotate back to the original position. At this time, because a one-way bearing 513 is provided between driven sprocket 525 and shaft 511, when driven sprocket 525 rotates in the opposite direction (clockwise), shaft 511 and roller 512 connected to shaft 511 do not rotate. Thus, the one-way bearing 513 on shaft 511 makes roller 512 push pin 211 forward but not backward. This cycle repeats.

[0021] This invention uses a drive assembly 52 to drive a roller 512 connected to a rotating shaft 511 to rotate. Thanks to the drive of the roller 512, even with some obstruction, the fastener 211 can move down smoothly, reducing the risk of jamming of the fastener strip 21. The one-way bearing 513 on the rotating shaft 511 ensures that the roller 512 can only push the fastener 211 forward and not backward. The drive motor 521 drives the main sprocket 522 to rotate counterclockwise by a preset angle, which can only push one fastener 211 forward and then immediately return to its original position. This can avoid the waste of raw materials caused by multiple fasteners 211 being fed at the same time, making the operation more convenient and improving the fastener feeding efficiency.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
