Description

Technical Field

[0001] This utility model relates to the field of hot pressing equipment technology, and in particular to a hot pressing device for zipper belts. Background Technology

[0002] After the zipper tape is manufactured, plastic sheets are usually heat-pressed onto the ends to increase its rigidity, making it easier to cut and install the zipper pull. During the heat-pressing process, two plastic sheets are pressed onto the top and bottom sides of the zipper tape respectively. During the feeding process, because the plastic tape is relatively soft, its ends tend to droop naturally. This can cause the plastic tape, which should be above the zipper tape, to be fed below, resulting in inaccurate feeding. Summary of the Invention

[0003] This invention mainly solves the above-mentioned problems and provides a zipper tape hot pressing device that can accurately feed plastic tape.

[0005] As a preferred embodiment of the above solution, the locking clamp includes an upper abutment plate, a lower abutment plate, and a locking wheel driven by a motor. The locking wheel is located between the upper abutment plate and the lower abutment plate, and the plastic belt has two sections located between the locking wheel and the upper abutment plate and between the locking wheel and the lower abutment plate, respectively.

[0006] As a preferred embodiment of the above solution, the locking wheel is elliptical, the major axis of the locking wheel is greater than or equal to the distance between the upper and lower abutments, and the minor axis of the locking wheel is less than the distance between the upper and lower abutments.

[0007] As a preferred embodiment of the above solution, the upper and lower abutments are provided with rubber layers on their opposing sides.

[0008] As a preferred embodiment of the above solution, the damping feeder includes an upper clamping plate and a lower clamping plate, the upper clamping plate and the lower clamping plate are rotatably connected at their first ends, a through hole for the plastic strip to pass through is provided in the upper clamping plate and the lower clamping plate, and damping strips are provided at the openings at both ends of the through hole, the lower clamping plate is fixedly mounted on the slide table, and the slide table reciprocates in the second direction.

[0009] As a preferred embodiment of the above solution, the lower part of the second end of the upper clamping plate is provided with a wedge-shaped notch, and a wedge is provided in the wedge-shaped notch. The wedge remains stationary when the slide table drives the damping feed clamp to move horizontally.

[0010] As a preferred embodiment of the above solution, the lower end face of the upper hot press head and the upper end face of the lower hot press head are provided with several protrusions.

[0011] The advantages of this utility model are: it is equipped with a damping feeding clamp.

[0016] The technical solution of this utility model will be further described below through embodiments and in conjunction with the accompanying drawings.

[0017] Example:

[0018] This embodiment provides a zipper tape heat pressing device, such as... Figure 1 and Figure 2 As shown, the system includes a zipper conveying mechanism, a plastic belt conveyor, and a hot pressing mechanism. The zipper conveying mechanism includes several conveying rollers for conveying the zipper belt 13 along a first direction. The plastic belt conveying mechanism includes a locking clamp and a damping feed clamp arranged in sequence for conveying the plastic belt 12 along a second direction and transporting the plastic belt to the upper and lower sides of the zipper belt 13. The hot pressing mechanism is located at the intersection of the first and second directions and includes a base, an upper hot pressing head, and a lower hot pressing head. The upper hot pressing head has a cutter near the plastic belt conveying mechanism, and the base has a cutter groove corresponding to the cutter. The lower hot pressing head is located on the base corresponding to the upper hot pressing head, and the lower end face of the upper hot pressing head and the upper end face of the lower hot pressing head have several protrusions.

[0019] The locking clamp includes an upper abutment plate 1, a lower abutment plate 2, and a locking wheel 3 driven by a motor. The locking wheel 3 is located between the upper abutment plate 1 and the lower abutment plate 2. Two plastic strips 12 are respectively located between the locking wheel 3 and the upper abutment plate 1, and between the locking wheel 3 and the lower abutment plate 2. In this embodiment, the locking wheel 3 is elliptical in shape. The major axis of the locking wheel is greater than or equal to the distance between the upper abutment plate 1 and the lower abutment plate 2, and the minor axis of the locking wheel 3 is less than the distance between the upper abutment plate 1 and the lower abutment plate 2. Furthermore, a rubber layer is provided on the facing sides of the upper abutment plate 1 and the lower abutment plate 2. The locking clamp is used to lock the plastic strips. When it is necessary to lock the plastic strips, the motor drives the locking wheel 3 to rotate, causing the locking wheel 3 to press the two plastic strips onto the upper abutment plate 1 and the lower abutment plate 2 respectively. When it is necessary to release the lock and continue feeding, the motor drives the locking wheel 3 to rotate, causing the locking wheel to move away from the upper abutment plate 1 and the lower abutment plate 2.

[0020] The damping feed clamp includes an upper clamping plate 4 and a lower clamping plate 5. The upper clamping plate 4 and the lower clamping plate 5 are rotatably connected at their first ends. The lower clamping plate 4 is fixedly mounted on a slide table 7, which reciprocates in a second direction. The lower part of the second end of the upper clamping plate 4 has a wedge-shaped notch, and a wedge 6 is placed in the wedge-shaped notch. The wedge remains stationary when the slide table drives the damping feed clamp to translate. A through hole 14 for the plastic strip to pass through is provided through the upper clamping plate 4 and the lower clamping plate 5. Figure 3 As shown, damping strips 15 are provided at both ends of the through hole 14. When the slide table 7 moves the damping feeder towards the hot pressing mechanism, the upper clamping plate 4 will tilt up under the action of the wedge 6, and the plastic sheet in the upper clamping plate 4 will also tilt up, which can prevent the plastic strip in the upper clamping plate 4 from being conveyed below the zipper belt. In addition, under the action of the damping strips 15, when the locking clamp is not locked, the damping feeder can move the plastic strip along with it when moving towards the hot pressing mechanism; when the locking clamp is locked, the plastic strip will not move with the damping feeder when moving towards the locking clamp.

[0021] In this embodiment, the zipper tape heat-pressing device is initially in operation. Figure 1 In the state shown, when conveying the plastic belt, the locking clamp unlocks, and the slide 7 drives the damping feed clamp to move to the right. During the rightward movement, the damping feed clamp opens and moves the plastic belt horizontally, conveying the plastic belt to the upper and lower sides of the zipper belt 13. At this time, it is in the state of... Figure 2 As shown in the diagram, the locking clamp then locks in place, and the slide 7 drives the damping feed clamp to move to the left. The damping feed clamp closes during this leftward movement. Furthermore, due to the locking clamp's tightness, the plastic strip's inherent resilience prevents it from shifting horizontally during the leftward movement, ensuring the end of the plastic strip remains positioned on both sides of the zipper tape. Subsequently, the hot press head presses down, cooperating with the lower hot press head to hot press the plastic strip on both sides of the zipper tape onto the zipper head. During this hot pressing process, the cutter 10 cuts the plastic strip, separating it from the zipper tape. After hot pressing, the zipper tape conveyor mechanism moves the zipper tape horizontally a distance and repeats the above process.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
