Description

Technical Field

[0001] This utility model application relates to the field of drying technology, specifically a zipper dryer. Background Technology

[0002] Zippers, as a type of connector that uses continuously arranged teeth to join or separate items, are now widely used in clothing, bags, tents, etc. They are generally composed of teeth, a zipper pull, a front clip, a back clip, or a locking mechanism. A typical zipper has two chain straps, each with a row of teeth. The two rows of teeth are arranged alternately. The zipper pull holds the teeth on both sides and slides along the loop to engage or disengage the teeth. During the production and processing of zippers, after pickling, rinsing, or electroplating, they need to be dried.

[0003] In existing dryers, the zipper teeth mesh with each other to facilitate zipper winding and unwinding. This can cause the overlapping surfaces of the teeth to be missed during drying, resulting in uneven drying of the zipper and affecting subsequent processing. Summary of the Invention

[0004] To address the problem of inconvenient drying of zipper teeth gaps in existing zipper dryers, this invention provides a zipper dryer to solve the aforementioned problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A zipper dryer includes a drying chamber with an inlet and an outlet at the upper ends of both ends. Positioning guide rollers are rotatably connected to the lower part of the drying chamber inside the inlet and outlet. Guide rollers are rotatably connected to the upper and lower interiors of the drying chamber on opposite sides of the two positioning guide rollers. A drying fan with an air outlet extending into the interior of the drying chamber is provided on the top surface of the drying chamber. Several heating tubes are symmetrically arranged on the inner wall of the drying chamber between the guide rollers. A door is provided on the front side of the drying chamber, with its top rotatably connected to the top of the drying chamber and its bottom engaging and fixed to the drying chamber. Several partition guide plates are fixed to the outer surface of each positioning guide roller.

[0007] Furthermore, heat insulation plates are provided at both the upper and lower ends of the drying fan near the discharge port, and the ends of the heat insulation plates away from the guide rollers are fixed to the inner wall of the drying chamber.

[0008] Furthermore, each of the guide rollers and positioning guide rollers is configured as a horizontally placed I-shaped structure, and another set of heating tubes is provided inside the drying chamber between the positioning guide roller near the feed inlet end and the inner wall of the guide roller.

[0009] Furthermore, an observation window is embedded inside the door, a handle is fixed to the center of the front side of the door below the observation window, and dust filters are fixed to the air inlet and outlet of the drying fan.

[0010] Furthermore, fixing blocks are fixed on both sides of the lower part of the door, and fixing sleeve blocks are fixed on the side walls of the drying oven on both sides of the fixing blocks. Limiting rods are slidably connected inside the fixing sleeve blocks. A spring is fixed between the top of each limiting rod and the inside of the fixing sleeve block. A push block is fixed on the outer side of the top of each limiting rod, and the push blocks extend to the outer side of the fixing sleeve block.

[0011] Furthermore, each of the two fixing blocks has a groove on its top that mates with a limiting rod, each limiting rod is T-shaped, and each fixing block has a sliding groove on its side wall that mates with a push block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, multiple heating tubes heat and dry the chain teeth during drying. Combined with the top fan, the moisture in the gaps after the chain teeth are engaged can be dried better. The guide plates at both ends allow the chain to move orderly in the drying chamber, which solves the problem of inconvenient drying of the gaps between the chain teeth in existing zipper dryers, and improves the drying effect and uniformity of the dryer.

[0014] 2. In this utility model, by setting an openable box door on the front side of the box, it is convenient to pass the chain through each guide roller during drying, making it more convenient to feed materials when using the dryer and improving the convenience of using the dryer. The observation window inside the box door makes it easy to observe the drying status, and the heat insulation plate next to the discharge port allows the chain to be cooled.

[0021] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1 , Figure 2 and Figure 3 A zipper dryer includes a drying chamber 1. The upper parts of both ends of the drying chamber 1 have an inlet 2 and an outlet 3, respectively. A drying fan 4 near the outlet 3 has heat insulation plates 8 at both its upper and lower ends. The ends of the heat insulation plates 8 away from the guide rollers 5 are fixed to the inner wall of the drying chamber 1. Positioning guide rollers 7 are rotatably connected to the lower part of the drying chamber 1 inside the inlet 2 and outlet 3. Guide rollers 5 are rotatably connected to the upper and lower parts of the drying chamber 1 on opposite sides of the two positioning guide rollers 7. Each guide roller 5 and positioning guide roller 7 is configured as a horizontally placed I-shape. The positioning guide roller 7 near the inlet 2 is flush with the inner wall of the guide roller 5. Inside the drying chamber 1, there is another set of heating tubes 6. The top surface of the drying chamber 1 is provided with an air outlet that extends into the drying chamber 1. The air inlet and outlet of the drying fan 4 are both fixed with dust filters. Several heating tubes 6 are symmetrically arranged on the inner wall of the drying chamber 1 between the guide rollers 5. A door 9 is provided on the front side of the drying chamber 1. The top of the door 9 is rotatably connected to the top of the drying chamber 1. An observation window 16 is fixedly embedded inside the door 9. A handle is fixedly fixed on the middle of the front side of the door 9 below the observation window 16. The bottom of the door 9 is engaged and fixedly fixed to the drying chamber 1. Several partition guide plates 15 are fixed on the outer surface of each positioning guide roller 7.

[0023] Specifically, when the zipper needs to be dried, the drying chamber 1 is opened, and the zipper is inserted into the drying chamber 1 through the feed port 2. Each zipper passes around the bottom of the positioning guide roller 7 between two adjacent partition guide plates 15, then along the bottom of the lower guide roller 5 and the bottom of the upper guide roller 5 to the bottom of another positioning guide roller 7, and then exits through the discharge port 3. The drying chamber 1 is closed, and the drying fan 4 and heating pipe 6 are turned on to draw external airflow into the drying chamber 1. At the same time, the heating pipe 6 heats and dries the zipper inside the drying chamber 1. Meanwhile, the zipper at the discharge port 3 is connected to the winding roller of the winding machine. Under the obstruction of the heat insulation plate 8, the heated airflow moves towards the feed port 2 side, and at the same time, the air outlet of the drying fan 4 cools down the zipper on the right side of the heat insulation plate 8.

[0024] As an optimization solution, such as Figure 2 and Figure 4 As shown, fixing blocks 10 are fixed on both sides of the lower part of the door 9. Fixing sleeve blocks 11 are fixed on the side walls of the drying oven 1 on both sides of the fixing blocks 10. Limiting rods 12 are slidably connected inside the fixing sleeve blocks 11. The top of both fixing blocks 10 is provided with a groove that cooperates with the limiting rods 12. Each limiting rod 12 is T-shaped. Each side wall of the fixing sleeve block 11 is provided with a sliding groove that cooperates with the push block 14. A spring 13 is fixed between the top of each limiting rod 12 and the inside of the fixing sleeve block 11. A push block 14 is fixed on the outer side of the top of each limiting rod 12. The push blocks 14 extend to the outer side of the fixing sleeve block 11.

[0025] Specifically, when it is necessary to open the door 9, push the push blocks 14 on both sides upward, so that the push blocks 14 drive the limit rod 12 to compress the spring 13 and move upward until the limit rod 12 moves out of the fixed block 10. After it moves out, pull the handle to rotate the door 9, and the drying box 1 can be rotated and opened. After the zipper is loaded, pull the push block 14 upward and close the door 9, so that the door 9 fits against the side of the drying box 1. Release the push block 14, so that the limit rod 12 is pushed into the fixed block 10 under the push of the spring 13, and fix the door 9 to the drying box 1.
