An automatic feeding device that prevents the zipper pull from being scratched and soiled.

Abstract

This utility model relates to the technical field of zipper feeding equipment, and in particular to an automatic feeding device for preventing scratches and dirt on zipper heads. It includes a conveyor frame, a feeding mechanism for conveying zipper heads onto the conveyor frame, a linear vibratory feeder connected to the conveyor frame, a receiving plate located at the top of the conveyor frame near the side of the conveyor frame, a conveying plate located at the top of the conveyor frame and in contact with the zipper head seam, and a guide plate for transferring zipper heads from the receiving plate to the conveying plate. The feeding mechanism conveys external zipper heads to the receiving plate at the top of the conveyor frame. The zipper heads fed into the receiving plate are fed in a row, and any excess zipper heads fall from the guide plate. Under gravity, the zipper heads contact the conveying plate, and the seam of the zipper head is engaged with the conveying plate and continues to be conveyed to the right along with the conveying plate. This solves the problem that light-colored, dirt-prone zipper heads, when conveyed by existing vibratory feeders, are constantly in contact with and rub against the vibratory feeder, easily causing discoloration and scratches at the contact points.

Description

Technical Field

[0001] This utility model relates to the technical field of zipper feeding equipment, and in particular to an automatic feeding device that prevents the zipper head from being scratched and soiled. Background Technology

[0002] Currently, Chinese Patent Publication No. CN119387180A discloses an online visual recognition and automatic rejection mechanism for zipper heads, including a transmission device, a visual recognition device, and a rejection device. The transmission device includes a vibratory feeder and a guide rail assembly. The guide rail assembly includes an upper guard plate and a lower guard plate, forming a transmission channel for zipper heads. The vibratory feeder transmits zipper heads into the transmission channel. The visual recognition device is used to identify whether the zipper heads in the transmission channel are qualified. The lower guard plate has a first groove communicating with the transmission channel. The rejection device moves back and forth along the first groove. The upper guard plate has a notch corresponding to the first groove for the zipper head to pass through. This discloses the existing structure of conveying zippers via a vibratory feeder. However, light-colored, easily soiled zipper heads, such as red, pink, and white, are constantly in contact with and rub against the vibratory feeder when conveyed by the existing vibratory feeder, and the contact area is prone to discoloration and scratches. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes an automatic feeding device that prevents the zipper pull from being scratched and dirty, which solves the above technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an automatic feeding device for preventing scratches and dirt on the zipper pull, comprising a conveyor frame, a feeding mechanism for conveying the zipper pull to the conveyor frame, a linear vibrating plate connected to the conveyor frame, a receiving plate located on the top of the conveyor frame near the side of the conveyor frame, a conveying plate located on the top of the conveyor frame and in contact with the zipper pull seam, and a guide plate for transferring the zipper pull from the receiving plate to the conveying plate.

[0005] Furthermore, a material-removing rod is provided on one side of the conveyor plate. The distance between the non-pull tab side of the pull head and the pull seam is less than the distance between the middle position of the material-removing rod and the conveyor plate, which is less than the distance between the pull tab side of the pull head and the pull seam. The end of the material-removing rod is bent and extends above the conveyor plate, and extends from the front end of the conveyor plate to the rear end.

[0006] Furthermore, the material conveying mechanism includes a lifting frame, a plate conveyor belt disposed on the lifting frame, a collection station disposed at the bottom of the lifting frame, an inclined plate disposed in the collection station for housing the plate of the plate conveyor belt, and a docking plate disposed on the lifting frame for docking with the output pull head of the transfer mechanism.

[0007] Furthermore, a transfer mechanism is provided below the conveyor plate for transferring the receiving plate, guide plate, and conveyor plate drop head to the conveying mechanism.

[0008] Furthermore, the conveyor frame is provided with a collection plate below the receiving plate, guide plate and conveyor plate, and the collection plate is provided with a guide plate that is inclined from a top view on the side of the conveyor plate away from the guide plate.

[0009] Furthermore, the transfer mechanism includes a transfer frame, a first conveyor belt disposed on the transfer frame and connected to the conveying frame, and a transfer component for transferring the pull head on the first conveyor belt to the material conveying mechanism.

[0010] Furthermore, the top of the transfer frame is provided with a partition on the side of the first conveyor belt away from the conveyor frame, and the transfer component is a transfer plate on the side of the transfer frame opposite to the partition and the docking plate, which is used to guide the pull head of the first conveyor belt to the collection station.

[0011] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0012] This automatic feeding device for zipper pulls, designed to prevent scratches and dirt, utilizes a conveying mechanism. This mechanism transports external zipper pulls to a receiving plate at the top of the conveyor frame. A linear vibrating feeder then conveys the zipper pulls from the receiving plate towards the conveyor plate. The zipper pulls pass from the receiving plate through a guide plate, the width of which is limited to a single row of zipper pulls. The zipper pulls fed into the receiving plate are fed in a single row, with any excess pulls falling from the guide plate. Because the angle between the guide plate and the conveyor plate is greater than 45 degrees, the zipper pulls, under gravity, come into contact with the conveyor plate. The gaps in the zipper pulls are then engaged with the conveyor plate and continue to be conveyed to the right. Puller pulls that are not engaged fall from the end of the guide plate. This design avoids the zipper pulls being spirally lifted and conveyed onto the conveyor plate by the vibrating feeder, reducing the contact time and distance between the zipper pulls and the vibrating feeder. This solves the problem of light-colored, easily soiled zipper pulls constantly rubbing against the vibrating feeder, leading to discoloration and scratches at the contact points.

[0013] The transfer mechanism is designed so that when the first conveyor belt transports the zipper heads, the zipper heads are mostly stationary. The zipper heads that fall from the receiving plate, guide plate, and conveyor plate can be recycled back into the collection station via the first conveyor belt and transfer plate for further screening. Compared with the existing vibratory feeder, which has a longer vibration contact time and distance for light-colored zipper heads, the zipper heads are almost stationary when transported by the first conveyor belt and plate conveyor belt, resulting in less wear on the zipper heads. This avoids the problems of dirt, discoloration, and scratches that easily occur when the vibratory feeder transports light-colored zipper heads. Attached Figure Description

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0023] refer to Figures 1 to 7 This embodiment provides an automatic feeding device for preventing scratches and dirt on zipper pulls, including a conveyor frame 1, a feeding mechanism 2 for conveying zipper pulls onto the conveyor frame 1, a linear vibrating plate 3 connected to the conveyor frame 1, a receiving plate 4 located on the top of the conveyor frame 1 near the side of the conveyor frame 1, a conveying plate 5 located on the top of the conveyor frame 1 and in contact with the zipper pull seam, and a guide plate 6 for transferring zipper pulls from the receiving plate 4 to the conveying plate 5. The guide plate 6 and the conveying plate 5 form an angle of 45 degrees to 90 degrees, and part of the zipper pull seam is conveyed and transferred through the receiving plate 4 and falls into the conveying plate 5.

[0024] The material conveying mechanism 2 transports the external pull heads to the receiving plate 4 at the top of the conveyor frame 1. The linear vibrating plate 3 transports the pull heads on the receiving plate 4 toward the conveyor plate 5. The pull heads pass from the receiving plate 4 through the guide plate 6. The guide plate 6 is only wide enough to accommodate a single row of pull heads. The pull heads input into the receiving plate 4 are input in a row. The excess pull heads will fall from the guide plate 6. Since the angle between the guide plate 6 and the conveyor plate 5 is greater than 45 degrees, the pull heads will contact the conveyor plate 5 under the action of gravity. The gaps in the pull heads will be stuck into the conveyor plate 5 and continue to be transported to the right with the conveyor plate 5. The pull heads that are not stuck into the conveyor plate 5 will fall from the end of the guide plate 6.

[0025] The inclination of the guide plate 6 gradually increases from the side closer to the receiving plate 4 to the side farther away from the receiving plate 4. When the pull head is conveyed from the receiving plate 4 to the guide plate 6, the inclination angle of the guide plate 6 is small. During the conveying process, it moves close to the top of the conveying plate 5 and the top surface of the guide plate 6, and it is not easy to slip off the conveying plate 5 and the guide plate 6. As the inclination angle of the guide plate 6 increases, under the action of gravity, it will gradually approach the upright state and be stuck on the conveying plate 5. The pull head that is not stuck on the conveying plate 5 will fall off the guide plate 6 and the conveying plate 5 more quickly due to the increased angle of the guide plate 6.

[0026] A material-removing rod 7 is provided on one side of the conveyor plate 5. The distance between the non-pull tab side of the pull head and the pull seam is less than the distance between the middle position of the material-removing rod 7 and the conveyor plate 5, which is less than the distance between the pull tab side of the pull head and the pull seam. The end of the material-removing rod 7 is bent and extends above the conveyor plate 5, and extends from the front end to the rear end of the conveyor plate 5. After the pull head is on the conveyor plate 5, part of the pull tab of the pull head is located on the front end face of the conveyor plate 5, and part of the pull tab of the pull head is located on the rear end face of the conveyor plate 5. The pull head direction is required to be uniform after output.

[0027] With the setting of the ejector bar 7, since the distance between the middle position of the ejector bar 7 and the conveyor plate 5 is greater than the distance between the non-pulling side of the pull head and the pull seam, when the pulling side of the pull head does not move towards the ejector bar 7 on the conveyor plate 5, it will pass through the ejector bar 7 and move to the end of the conveyor plate 5. And since the distance between the middle position of the ejector bar 7 and the conveyor plate 5 is less than the distance between the pull head and the pull seam, when the pulling side of the pull head moves towards the ejector bar 7 on the conveyor plate 5, it is blocked by the ejector bar 7. As the subsequent pull heads continue to convey, the pull head with the pulling side facing the ejector bar 7 is squeezed by the subsequent input pull head, and guided by the bending position at the end of the ejector bar 7, it will fall off the conveyor plate 5.

[0028] The material conveying mechanism 2 includes a lifting frame 201, a plate conveyor belt 202 disposed on the lifting frame 201, a collection station 203 disposed at the bottom of the lifting frame 201, an inclined plate 204 disposed in the collection station 203 with its end close to the built-in plate of the plate conveyor belt 202, and a docking plate 205 disposed on the lifting frame 201 for docking the output pull head of the transfer mechanism 8. The collection station 203 is preferably a receiving frame for collecting the pull head.

[0029] The pull head is poured into the collection station 203. The plate conveyor belt 202 drives the pull head in the bottom collection station 203 to be lifted and moved upward. When it moves to the receiving plate 4, the built-in plate on the plate conveyor belt 202 will tilt downward. The pull head on the built-in plate of the plate conveyor belt 202 will fall onto the receiving plate 4. Then, it will continue to be guided by the receiving plate 4 to fall onto the guide plate 6. The transfer mechanism 8 will also transfer the pull head that has fallen from the guide plate 6 and the conveyor plate 5 to the collection station 203. The pull head can be conveyed back and forth.

[0030] Below the conveyor plate 5 is a transfer mechanism 8 for transferring the receiving plate 4, guide plate 6 and the pull head of the conveyor plate 5 to the conveying mechanism 2. The transfer mechanism 8 facilitates the transfer of the pull head of the receiving plate 4, guide plate 6 and conveyor plate 5 to the conveying mechanism 2.

[0031] The conveyor frame 1 is provided with a collection plate 101 below the receiving plate 4, guide plate 6 and conveyor plate 5. A transition plate 102 is provided between the collection plate 101 and the transfer mechanism 8. A guide plate 103 is provided on the collection plate 101 on the side of the conveyor plate 5 away from the guide plate 6, which is inclined from a top view. This structure is a preferred design. The collection plate 101 can make the linear vibratory feeder 3 better transmit vibration to the receiving plate 4, guide plate 6 and conveyor plate 5.

[0032] The pull heads falling from the receiving plate 4, guide plate 6, and conveyor plate 5 will fall onto the collecting plate 101. Under the action of the linear vibrating plate 3, they will move towards the guide plate 103. After adhering to the guide plate 103, they will move forward to the transition plate 102 and then fall onto the transfer mechanism 8. This facilitates the collection and transfer of pull heads that are not stuck into the conveyor plate 5 and pull heads that are rejected by the rejection bar 7 to the transfer mechanism 8. Alternatively, the collecting plate 101, guide plate 103, and transition plate 102 can be omitted, and the transfer mechanism 8 can be directly extended below the conveyor plate 5 and guide plate 6 with the built-in first conveyor belt 802. The pull heads falling from the receiving plate 4, guide plate 6, and conveyor plate 5 will fall directly onto the first conveyor belt 802.

[0033] The transfer mechanism 8 includes a transfer frame 801, a first conveyor belt 802 disposed on the transfer frame 801 and connected to the conveyor frame 1, and a transfer component 803 for transferring the pull head of the first conveyor belt 802 to the material conveying mechanism 2. The top of the transfer frame 801 is provided with a partition 804 on the side of the first conveyor belt 802 away from the conveyor frame 1. The transfer component 803 is a transfer plate on the transfer frame 801 between the side opposite the partition 804 and the docking plate 205, and is used to guide the pull head of the first conveyor belt 802 to the collection station 203.

[0034] The pull head drops from the receiving plate 4, guide plate 6, and conveyor plate 5 and is conveyed through the transition plate 102 to the top surface of the first conveyor belt 802. Then, as the first conveyor belt 802 moves forward, the pull head will move forward. The transfer plate is arc-shaped or oblique. The pull head on the first conveyor belt 802 will be guided by the transfer plate to move into the collection station 203. The transfer component 803 can also be a cylinder-driven plate to push the pull head on the first conveyor belt 802 into the collection station 203. However, this design requires the addition of an extra cylinder component, which increases the cost. The transfer plate is the preferred solution.
