[0002] Hook and loop fasteners, also known as Velcro, are a common connecting accessory used in clothing. They have two sides, one side is made of fine and soft fibers, and the other side is made of stiffer, hooked bristles. The product is widely used in clothing, shoes, hats, gloves, bags, sofas, cushions, etc. The sizing and shaping device is a relatively important piece of equipment in the production process of hook and loop fasteners.
[0003] Existing sizing and setting devices are relatively simple. When the semi-finished hook and loop fasteners after sizing enter the drying device for drying and setting, a lot of sizing residue remains on the surface of the hook and loop fasteners. The dripping sizing residue can easily contaminate the drying equipment, affect the use of the drying equipment, waste raw materials, and is not conducive to drying. Therefore, a sizing, drying, and setting device for hook and loop fastener production is needed to improve the above problems. Utility Model Content

[0025] 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. Example
[0026] Please see Figure 1 A sizing, drying and shaping device for producing hook and loop fasteners includes a sizing box 1 with symmetrical through holes 2. Hook and loop fasteners enter and exit the sizing box 1 through the two through holes 2 for sizing.
[0027] Please see Figure 1 , Figure 2 and Figure 4A scraping mechanism is provided on the inner wall of the sizing box 1. The scraping mechanism includes a movable plate 14. A first scraper 12 and a mounting plate 13 are fixedly installed on the sizing box 1. An adjusting bolt 16 is rotatably installed on the movable plate 14 and screwed onto the mounting plate 13. A second scraper 15 is fixedly installed at the bottom of the movable plate 14. The second scraper 15 is in contact with the inner wall of the sizing box 1. By rotating the adjusting bolt 16, the adjusting bolt 16 drives the movable plate 14 to move. The movable plate 14 drives the second scraper 15 to move. The position of the second scraper 15 is adjusted according to actual needs. The cooperation of the first scraper 12 and the second scraper 15 scrapes the sizing adhesive tape and removes excess slurry.
[0028] Please see Figure 2 and Figure 4 The second scraper 15 is limited by a limiting mechanism, which includes two limiting blocks 17. The two limiting blocks 17 are symmetrically fixed on the second scraper 15. The slurry box 1 has two limiting grooves 18 corresponding to the two limiting blocks 17. The two limiting blocks 17 are slidably connected to the two limiting grooves 18 respectively. When the second scraper 15 moves, the two limiting blocks 17 slide in the two limiting grooves 18 respectively, so that the second scraper 15 moves more stably.
[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5A drying mechanism is provided on the sizing box 1, which includes a drying chamber 3. The drying chamber 3 is fixedly installed on the outer wall of the sizing box 1. A dryer 4 is fixedly installed on the drying chamber 3. A drying pipe 5 is connected to the output end of the dryer 4. The drying pipe 5 is located inside the drying chamber 3. Multiple heating pipes 6 are provided inside the drying chamber 3. The hook and loop fastener enters the drying chamber 3 for drying. The dryer 4 converts the outside air into hot air. The outside air is filtered by a filter plate 8. The hot air is introduced into the drying chamber 3 through the drying pipe 5 to blow and dry the hook and loop fastener. The multiple heating pipes 6 assist in the drying process. A fixing plate 7 is connected to the input end of the dryer 4. A first sliding groove is provided on the fixing plate 7. A second slide groove is provided at both ends of the slide groove. A filter plate 8 is slidably installed in the first slide groove. Two sliders 9 are symmetrically fixedly installed on the filter plate 8. The two sliders 9 are slidably connected to the two second slide grooves respectively. A first spring 10 is fixedly installed on each of the two second slide grooves. A pressing block 11 is fixedly installed on each of the two first springs 10. The two pressing blocks 11 are slidably connected to the two second slide grooves respectively. Two pressure plates are symmetrically rotated on the fixing plate 7. The bottom ends of the two pressure plates are attached to the top end of the filter plate 8. When it is necessary to clean or replace the filter plate 8, the limiting operation of the fixing plate 7 on the filter plate 8 is released, and the filter plate 8 is taken out for cleaning or replacement, thereby improving the air filtration efficiency and realizing the sizing and drying operation of the hook and loop fastener.
[0030] Please see Figure 3 and Figure 5 Multiple second springs 19 are fixedly installed on the first slide groove. The filter plate 8 moves more stably through contact with the multiple second springs 19.
[0031] Please see Figure 3 and Figure 5 It should also be noted that an auxiliary plate 20 is fixedly installed on the filter plate 8, which facilitates the removal of the filter plate 8.
[0032] Please see Figure 3 and Figure 5 Stabilizing rods 21 are fixedly installed on both second slide grooves. The two sliders 9 are slidably connected to the two stabilizing rods 21 respectively. The setting of the two stabilizing rods 21 makes the two sliders 9 and the filter plate 8 more stable.
[0033] Please see Figure 1 An observation window 22 is provided on the drying oven 3, which facilitates timely observation of the internal condition of the drying oven 3.
[0034] In summary, when using this sizing, drying, and shaping device for hook and loop fastener production, the filter plate 8 is picked up by the auxiliary plate 20, and the filter plate 8 slides against the fixed plate 7. The two sliders 9 press against the two pressing blocks 11, thereby compressing the two first springs 10. The filter plate 8 contacts multiple second springs 19, causing them to compress as well. Rotating the two pressure plates limits the position of the filter plate 8, thus completing the installation of the filter plate 8. The hook and loop fastener enters and exits the sizing box 1 through the two through holes 2 for sizing. Rotating the adjusting bolt 16 moves the moving plate 14, which in turn moves the moving plate 14. Plate 14 drives the second scraper 15 to move. The position of the second scraper 15 is adjusted according to actual needs. With the cooperation of the first scraper 12 and the second scraper 15, the slurry is scraped off the hook and loop tape after it has been slurried. The hook and loop tape enters the drying box 3 for drying. The dryer 4 converts the outside air into hot air. The outside air is filtered by the filter plate 8. The hot air is introduced into the drying box 3 through the drying pipe 5 to blow and dry the hook and loop tape. Multiple heating pipes 6 assist in the drying process. When it is necessary to clean or replace the filter plate 8, the fixing plate 7 is released from the limiting operation of the filter plate 8, and the filter plate 8 can be taken out for cleaning or replacement.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
