Description

Technical Field

[0001] This utility model relates to the field of zipper feeding technology, specifically to a guiding device for feeding zipper tape. Background Technology

[0002] Traditional bag-making machines are prone to zipper tape flipping during feeding, resulting in twisted knots in the middle during subsequent heat sealing. This renders the bags unusable, creating defective or scrap products. The high scrap rate increases production costs and reduces production efficiency.

[0003] In the prior art, a zipper tape guiding device with publication number "CN 219618616 U" includes a base with a receiving groove on its inner side. A connecting stud is threaded into the inner side of the receiving groove, and a first rotating wheel is threaded into the outer side of the connecting stud. This invention improves the adjustability of the device by setting a connecting stud, allowing the support base to rotate through adjustment. The addition of a belt makes the movement of the zipper tape more convenient, improving the device's ease of use. The first clamping plate allows the device to be adjusted according to the width of the zipper tape, improving its stability. The second clamping plate allows the device to be adjusted according to the thickness of the zipper tape, further improving its stability and preventing the zipper tape from flipping over. This solves the problem of zipper tape flipping easily during loading in existing zipper tape guiding devices.

[0004] However, in the aforementioned patents, the existing devices adjust the width, thickness, and angle using multiple studs and wheels, which is cumbersome to operate and inefficient when frequently changing zipper tape specifications. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model proposes a guiding device for feeding zipper tape.

[0006] To achieve the above-mentioned technical effects, the present invention adopts the following solution: A guiding device for feeding zipper tape, comprising: Base; A support base is rotatably mounted on the upper end of the base, and a drive belt is provided on the upper end of the support base; An adjustment assembly, located at the upper end of the support base, includes a width adjustment mechanism and a thickness adjustment mechanism. The width adjustment mechanism includes two symmetrically arranged first clamping plates, which are connected by a quick-locking mechanism. The quick-locking mechanism includes a handle and a connecting rod. The handle is connected to the two first clamping plates via the connecting rod to achieve rapid relative movement of the two first clamping plates.

[0007] In a preferred embodiment, the thickness adjustment mechanism includes a second clamping plate that is raised and lowered, and a spring pressing mechanism is provided above the second clamping plate. The spring pressing mechanism includes a spring and a pressure plate. The spring is pre-tightened by an adjusting bolt to control the pressing force of the second clamping plate on the zipper tape.

[0008] In a preferred embodiment, an angle locking mechanism is provided between the support base and the base. The angle locking mechanism includes a toothed disc and a pawl. The toothed disc is fixed to the bottom of the support base, and the pawl is located on the base and engages and releases with the toothed disc through a lever controller.

[0009] In a preferred embodiment, both the first clamping plate and the second clamping plate have rubber pads on the side opposite to the zipper tape.

[0010] In a preferred embodiment, the surface of the belt is provided with a number of anti-slip marks.

[0011] Compared with existing technologies, the beneficial effects are: This utility model has a simple structure and is easy to use. It achieves rapid opening and closing of the first clamping plate through a quick locking mechanism, thereby improving adjustment efficiency. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] A guide device for feeding zipper tape includes: a base 10, a support 20, and an adjustment component 40.

[0016] The base 10 serves as a stabilizing component of the guiding device.

[0017] The support base 20 is rotatably mounted on the upper end of the base 10, and a transmission belt 30 is provided on the upper end of the support base 20.

[0018] The adjustment assembly 40 is located at the upper end of the support base 20 and includes a width adjustment mechanism 401 and a thickness adjustment mechanism 402. The width adjustment mechanism 401 includes two symmetrically arranged first clamping plates 4011. The two first clamping plates 4011 are connected by a quick locking mechanism. The quick locking mechanism includes a handle 4013 and a connecting rod 4012. The handle 4013 is connected to the two first clamping plates 4011 through the connecting rod 4012 to realize the rapid relative movement of the two first clamping plates 4011.

[0019] The quick-locking mechanism enables the rapid opening and closing of the first clamping plate 4011, improving adjustment efficiency.

[0020] In a preferred embodiment, the thickness adjustment mechanism 402 includes a second clamping plate 4021 that is vertically mounted. A spring 4022 clamping mechanism is located above the second clamping plate 4021. The spring 4022 clamping mechanism includes a spring 4022 and a pressure plate. The spring 4022 is pre-tightened by an adjusting bolt 4023 to control the clamping force of the second clamping plate 4021 on the zipper tape. The spring 4022 clamping mechanism ensures a more uniform clamping force on the zipper tape from the second clamping plate 4021, preventing deviation. In a preferred embodiment, an angle locking mechanism is provided between the support base 20 and the base 10. The angle locking mechanism includes a gear disc 202 and a pawl 203. The lower end of the support base 20 is rotatably mounted on the upper end of the base 10 via a rotating shaft 201. The gear disc 202 is fixed to the rotating shaft 201. The pawl 203 is located on the base 10 and engages and releases with the gear disc 202 via a lever controller. The angle locking mechanism enhances the connection stability between the support base 20 and the base 10.

[0021] In a preferred embodiment, both the first clamping plate 4011 and the second clamping plate 4021 have rubber pads on the side opposite to the zipper tape.

[0022] In a preferred embodiment, the surface of the belt is provided with a number of anti-slip marks.
