Description

Technical Field

[0001] This utility model relates to the field of zipper forming technology, and in particular to an integrated zipper forming device. Background Technology

[0002] A zipper is a connecting device that uses continuously arranged teeth (metal / nylon / plastic) to engage or disengage with a zipper pull, enabling the rapid opening and closing of two pieces of fabric. It is mainly composed of the following components;

[0003] Chain teeth: Pairs of tooth-like structures arranged along the edge of the fabric strip, available in three types: metal, injection molded, and spiral (nylon);

[0004] Fabric tape: The fabric tape that carries the chain teeth, usually made of polyester or cotton;

[0005] Sliding head: A sliding component with an internal "Y"-shaped guide groove to control the engagement and disengagement of the chain teeth;

[0006] Top stop / bottom stop: End fixing components that restrict the sliding of the slider;

[0007] The zipper machine is used during the processing to form the zipper as a whole. The conveyor line runs through the entire production process. When processing plastic zipper teeth, the plastic injection molding is limited by the production process and the insufficient precision of traditional equipment. As a result, there are burrs on the outer wall of the plastic teeth, the yield rate decreases and the subsequent processing cost increases. To address this, we propose an integrated zipper forming equipment to solve the existing problems. Utility Model Content

[0008] The purpose of this invention is to address the problems existing in the background technology by proposing an integrated zipper forming device.

[0009] To achieve the above objectives, this utility model provides the following technical solution: an integrated zipper forming device, comprising a frame one, a motor, a frame two, a base, a hot air blower, and an air knife. An upper support frame is provided above the base. Frame one and frame two are symmetrically distributed between the base and the upper support frame. A motor is provided at the upper end of the upper support frame. A screw, rotatably mounted inside the base with relatively distributed threads on its outer wall, is provided at the motor output end. Nuts, symmetrically distributed and connected to frame one and frame two, are threaded onto the outer wall of the screw. Symmetrically distributed upper support wheels are provided inside frame one, and a conveyor belt one is sleeved on the outer wall of each upper support wheel. Symmetrically distributed lower support wheels are provided inside frame two, and a conveyor belt two is sleeved on the outer wall of each lower support wheel. A hot air blower is provided at the upper end of the upper support frame. An air knife is provided on one side of frame one and frame two.

[0010] Preferably, a transversely distributed conveying channel is provided between conveyor belt one and conveyor belt two, and limit wheels are provided at both ends of the upper support wheel and the lower support wheel. The conveying channel is suspended between conveyor belt one and conveyor belt two, so that the chain teeth are effectively exposed to the outside.

[0011] Preferably, an upper support roller is rotatably mounted inside the frame, which is in contact with the upper inner wall of the conveyor belt, and a lower support roller is rotatably mounted inside the frame, which is in contact with the lower inner wall of the conveyor belt. The upper support roller provides rolling support to the upper inner wall of the conveyor belt, and the lower support roller provides rolling support to the lower inner wall of the conveyor belt.

[0012] Preferably, an upper support roller 2 is rotatably mounted inside the frame 2, which is in contact with the upper inner wall of the conveyor belt 2, and a lower support roller 2 is rotatably mounted inside the frame 2, which is in contact with the lower inner wall of the conveyor belt 2. The upper support roller 2 provides rolling support to the upper inner wall of the conveyor belt 2, and the lower support roller 2 provides rolling support to the lower inner wall of the conveyor belt 2.

[0013] Preferably, the base has an internal mounting groove, and three sets of guide rods are provided between the base and the upper support frame. Both the front and rear ends of frame one and frame two are provided with sliding sleeves that are slidably fitted onto the outer walls of the guide rods. The mounting groove is used for inserting and installing parts. Frame one and frame two slide on the outer walls of the guide rods via the sliding sleeves, providing longitudinal sliding guidance for frame one and frame two.

[0014] Preferably, the outer wall of the air knife is provided with a fixing plate connected to the inner wall of the upper support frame. The air knife has a downward-facing lower blade and an upward-facing upper blade at both ends, with the lower blade corresponding to the conveying channel. The air knife delivers hot air through the lower blade, directly acting on the plastic chain teeth exposed to the outside and located inside the conveying channel, while avoiding direct action on the fabric belt conveyed between conveyor belt one and conveyor belt two.

[0015] Preferably, the hot air blower output end is equipped with a hot air universal tube that penetrates the air knife, and the upper support frame is equipped with an electromagnetic brake that is sleeved on the outside of the motor output end. The electromagnetic brake prevents the motor output end from rotating arbitrarily, ensuring the stability of the screw. The hot air universal tube can be bent, facilitating the effective delivery of hot air when the spacing between frame one and frame two is adjusted. The delivery channel for spacing adjustment facilitates the delivery of the fabric belt within a certain thickness range.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model uses two sets of conveyor belts, conveyor belt one and conveyor belt two, connected by chain teeth for conveying. The chain teeth are suspended at the center of conveyor belt one and conveyor belt two. The fabric belt is clamped and conveyed by conveyor belt one and conveyor belt two. The conveying structure is installed on the conveyor line of the production line. Because the fabric belt is strip-shaped during production and has a long overall structure, it can effectively move within conveyor belt one and conveyor belt two through its own transmission force on the production line. The friction force drives conveyor belt one and conveyor belt two to rotate. During the conveying process, the hot air blower delivers hot air through the upper and lower blades of the air knife to the plastic chain teeth. Under the action of high temperature, the burrs are melted and eliminated. The burrs are removed during the production stage, which improves the appearance quality of the chain teeth, increases the yield rate, and reduces subsequent processing costs.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5As shown, the present invention proposes an integrated zipper forming equipment, including a frame 1 3, a motor 2, a frame 2 8, a base 9, a hot air blower 13, and an air knife 16. An upper support frame 19 is provided above the base 9. The frame 1 3 and the frame 2 8 are symmetrically distributed between the base 9 and the upper support frame 19. The motor 2 is provided at the upper end of the upper support frame 19. The output end of the motor 2 is provided with a screw 23 that is rotatably installed inside the base 9 and whose outer wall threads are relatively distributed. Nuts 20 that are symmetrically distributed and connected to the frame 1 3 and the frame 2 8 are threaded on the outer wall of the screw 23. The frame 1 3 is provided with symmetrically distributed upper support wheels 1. The outer wall of the upper support wheels 1 is sleeved with a conveyor belt 1 6. The frame 2 8 is provided with symmetrically distributed lower support wheels 7. The outer wall of the lower support wheels 7 is sleeved with a conveyor belt 2 12. The hot air blower 13 is provided at the upper end of the upper support frame 19. An air knife 16 is provided on one side of the frame 1 3 and the frame 2 8.

[0026] A transversely distributed conveying channel is provided between conveyor belt 6 and conveyor belt 12, and limit wheels are provided at both ends of the upper support wheel 1 and the lower support wheel 7.

[0027] The frame 3 is rotatably mounted with an upper support roller 4 that fits against the inner wall of the upper end of the conveyor belt 6, and the frame 3 is rotatably mounted with a lower support roller 5 that fits against the inner wall of the lower end of the conveyor belt 6.

[0028] The frame 28 has an upper support roller 210 that is attached to the inner wall of the upper end of the conveyor belt 212, and the frame 28 has a lower support roller 211 that is attached to the inner wall of the lower end of the conveyor belt 212.

[0029] The base 9 has an installation groove inside. Three sets of guide rods 14 are provided between the base 9 and the upper support frame 19. Sliding sleeves 15 that are slidably sleeved on the outer wall of the guide rods 14 are provided at both the front and rear ends of the frame 1 3 and the frame 2 8.

[0030] The outer wall of the air knife 16 is provided with a fixing plate 17 that is connected to the inner wall of the upper support frame 19. The air knife 16 has a lower blade 21 with an opening facing downward and an upper blade 22 with an opening facing upward, respectively. The lower blade 21 corresponds to the conveying channel.

[0031] The hot air blower 13 is provided with a hot air universal pipe 24 that penetrates the air knife 16 at the output end, and an electromagnetic brake 18 that is sleeved on the outside of the output end of the motor 2 is provided at the upper end of the upper support frame 19.

[0032] Based on the implementation steps of Example 1: The fabric belt with the embedded plastic chain teeth is introduced into the transverse conveying channel formed by conveyor belt 6 and conveyor belt 12. The smooth movement of the fabric belt is ensured by the rolling support of upper support roller 4, lower support roller 5, upper support roller 10, and lower support roller 11. At the same time, the limit wheel prevents the fabric belt from running off-center. The chain teeth are fully exposed because they are suspended in the center of the conveying channel. According to the thickness of the fabric belt, the motor 2 is started to drive the screw 23 to rotate, which drives the frame 3 and the frame 8 to move synchronously in opposite directions along the guide rod 14, thereby adjusting the distance between conveyor belt 6 and conveyor belt 12. The electromagnetic brake 18 locks the position of the screw 23 to ensure the distance is stable.

[0033] The hot air blower 13 delivers high-temperature airflow to the air knife 16 through the hot air universal tube 24. The airflow is precisely sprayed from the upper blade 22 and the lower blade 21 onto the suspended chain teeth surface, causing the burrs to melt and fall off due to heat. The air knife 16 is designed to prevent the hot air from directly contacting the fabric belt, thus preventing damage to the fabric. The fabric belt moves forward autonomously under the friction drive of the conveyor belt. After the deburred chain teeth are cooled, they enter the next process for the assembly of the pull head. The entire process requires no manual intervention.

[0034] The clamping design of conveyor belt 6 and conveyor belt 12 ensures that the fabric belt is conveyed in the center, and the chain teeth are suspended in the conveying channel, providing an unobstructed operating space for hot air treatment. The screw 23 and nut 20 transmission mechanism realizes millimeter-level precise adjustment of the conveyor belt spacing, which is suitable for 0.5~3mm fabric belts. The guide rod 14 and the sliding sleeve 15 ensure the stability of movement. The bidirectional nozzle of the air knife 16 controls the hot air temperature at 180~220℃. It is worth noting that it ensures that within the plastic melting temperature range, it only acts on the chain tooth burrs and avoids the fabric belt from being deformed by heat.

[0035] Traditional processes rely on manual polishing, resulting in a lower yield rate. This equipment improves the yield rate and reduces subsequent processing costs through online hot-melt treatment. The hot air universal tube 24 automatically bends according to the spacing adjustment, ensuring that the airflow is always aligned with the chain teeth, solving the problem that the traditional fixed air knife 16 cannot adapt to different belt thicknesses. The linkage mechanism between the screw 23 and the guide rod 14 enables rapid adjustment of the conveyor belt spacing, is compatible with multiple belt specifications, and improves switching efficiency compared to the traditional bolt fixing method. The suspended conveying design avoids friction between the chain teeth and mechanical parts, preventing secondary burrs. The electromagnetic brake 18 eliminates the rotation error of the screw 23, and the spacing control accuracy reaches ±0.1mm, far exceeding the traditional manual adjustment. The hot air blower 13 adopts PID temperature control technology, which reduces energy consumption compared to conventional heating systems, and the hot air is recycled to reduce waste.

[0036] By integrating suspended conveying, dynamic distance adjustment, and directional hot air technology, online deburring of plastic zipper teeth has been achieved, solving the problem of burr defects caused by insufficient precision of traditional equipment. It can be effectively integrated with existing production lines, significantly improving production efficiency and product consistency, and is suitable for high-quality zipper manufacturing in large-scale clothing, bags and other fields.
