Description

Technical Field

[0001] This utility model relates to the field of zipper production technology, and more specifically to an automatic pre-processing device for zipper pulls. Background Technology

[0002] After the zipper pull is manufactured, its surface will have a large amount of processing residue, oil, fingerprints, dust, and other dirt and impurities. These dirt and impurities will affect the appearance of the zipper pull and also affect subsequent processing operations (such as electroplating and painting). Therefore, after the zipper pull is manufactured, it will generally undergo a pre-treatment process to remove oil and dirt.

[0003] The current pre-treatment method for small hardware products such as zipper pulls in China typically involves placing batches of pulls into a material box, then sequentially immersing the box in multiple cleaning tanks containing different solutions for degreasing, rinsing, and other cleaning operations, before finally removing and drying them. In existing cleaning systems, these processes are performed separately and independently, each requiring manual labor. This not only results in extremely high labor intensity and low cleaning efficiency, but also leads to numerous, fragmented cleaning devices, a large workspace, and high operating costs. Utility Model Content

The second servo motor is connected to the gearbox for transmission. The first helical gear meshes with the circular gear disk for transmission, and the circular gear disk meshes with the second helical gear for transmission.

[0009] Furthermore, the loading station is equipped with a loading elevator for conveying the material to be cleaned into the material frame.

[0010] Furthermore, the unloading station is equipped with a lifting cylinder for supporting the material shaft, and the annular hand guard is provided with a notch at the position corresponding to the unloading station for allowing the material shaft to tilt downwards and fall. The output shaft of the lifting cylinder is located below the notch and is used to support the material shaft.

[0011] Furthermore, the processing station includes an oil removal station, a water washing station, and a drying station in sequence. Each of the oil removal station and the water washing station is equipped with an independent water tank, a water pump connected to the water tank, and a spray head connected to the water pump.

The drying station is equipped with a circulating hot air fan, and the air outlet of the circulating hot air fan faces the material frame.

[0012] Furthermore, the degreasing station includes two adjacent degreasing stations, the water washing station includes two adjacent water washing stations, and the drying station includes several adjacent drying stations.

[0013] Furthermore, the first of the two washing stations is an activation station, and the water tank in the activation station is filled with a weak acid solution.

[0014] Furthermore, it also includes a film coating station, which is inserted in the middle of several drying stations.

Detailed Implementation

[0023] The specific implementation of the present invention will now be described with reference to the accompanying drawings.

[0024] Reference Figure 1 and Figure 2An automatic pre-treatment device for zipper pulls includes a rotary worktable 10, a loading station 21, a unloading station 26, and several processing stations. The loading station 21, processing stations, and unloading stations 26 are arranged sequentially around the rotary worktable 10. The rotary worktable 10 can rotate around its center. At least one material frame 14 is provided on the rotary worktable 10 for placing the material to be cleaned. The material frame 14 passes sequentially through the loading station 21, processing station, and unloading station 26 as the rotary worktable 10 rotates. The loading station 21 is used to pour the material to be cleaned into the material frame 14. The processing stations are used to perform pre-treatment operations on the material to be cleaned. The unloading station 26 is used to unload the material to be cleaned from the material frame 14. In this embodiment, the material to be cleaned is a zipper pull.

[0025] Specifically, refer to Figures 1 to 3 The rotary table 10 is preferably a round table-shaped table, including a frame 11, a rotary table 12 rotatably mounted on the frame 11, and a first servo motor (not shown in the figure) for driving the rotary table 12 to rotate. A ring-shaped handguard 13 is fixedly mounted on the frame 11, the ring-shaped handguard 13 surrounds the rotary table 12, and is spaced a certain distance from the rotary table 12.

[0026] Reference Figure 2 and Figure 3 The rotary table 12 has several material frames 14, each corresponding to a material shaft 15. One end of the material shaft 15 is hinged to the rotary table 12, and the other end is fixedly connected to the material frame 14. The material frame 14 is preferably an elliptical frame structure, and its surface is covered with a stainless steel mesh (not shown in the figure) to prevent the pull head from falling out of the material frame 14 if it is too small. The material frame 14 can also be a stainless steel box with several through holes. One end of the material frame 14 has a feed inlet for feeding and discharging the pull head. The other end of the material frame 14 is fixedly connected to the material shaft 15. When the material shaft 15 is tilted upwards against the annular handguard 13, the feed inlet of the material frame 14 is tilted upwards to ensure that the pull head will not fall out of the feed inlet during processing.

[0027] Reference Figure 2 and Figure 3To further improve the pre-treatment quality of the feeder head, the material shaft 15 of this invention is preferably a rotatable material shaft 15, thereby driving the material frame 14 to rotate by rotating the material shaft 15. Specifically, the rotary table 12 is provided with a plurality of hinge seats 31 for hinged connection with the material shaft 15. The hinge seats 31 are preferably located on the bottom surface of the rotary table 12. Each hinge seat 31 rotatably supports a hinge shaft 32. The material shaft 15 is fixedly connected to the hinge shaft 32 through a connecting frame 33. The connecting frame 33 is an inverted U-shaped connecting frame 33. The two legs of the inverted connecting frame 33 are connected to the hinge shaft 32, and the top surface of the inverted connecting frame 33 is provided with a through hole for the material shaft 15 to pass through. In addition, in order to ensure that the material shaft 15 can rotate within the through hole of the inverted connecting frame 33, a bearing connected to the material shaft 15 can preferably be provided at the through hole.

[0028] Reference Figure 2 and Figure 3 The material shaft 15 is equipped with a material shaft rotation mechanism for driving the material shaft 15 to rotate. The material shaft rotation mechanism includes a second servo motor 41 fixedly mounted on the rotary table 12, a gearbox 42, a circular gear disk 43 mounted on the hinge shaft 32, a first helical gear 44 mounted on the output shaft of the gearbox 42, and a second helical gear 45 mounted on the material shaft 15. The second servo motor 41 and the gearbox 42 are connected by gear transmission. The first helical gear 44 meshes with the circular gear disk 43 for transmission, and the circular gear disk 43 meshes with the second helical gear 45 for transmission.

[0029] During transmission, the second servo motor 41 and the gearbox 42 operate in a transmission manner, and the first helical gear 44 on the output shaft of the gearbox 42 meshes with the circular gear disk 43, and the circular gear disk 43 meshes with the second helical gear 45, thereby driving the material shaft 15 to rotate, which in turn drives the material frame 14 to rotate.

[0030] Reference Figure 1 and Figure 2 The processing stations of this utility model include an oil removal station 22, a water washing station 23, an activation station, a film coating station 25, and a drying station 24. In this embodiment, the rotating worktable 10 has a total of twelve stations around its perimeter, which are arranged in the order of the rotation direction of the rotating worktable 10: a loading station 21, two oil removal stations 22, two water washing stations 23, three drying stations 24, one film coating station 25, two drying stations 24, and one unloading station 26. Among them, the first water washing station 23 is the activation station.

[0031] The loading station 21 is used to pour the zipper pulls into the material frame 14. Since the material opening of the material frame 14 is set at an upward angle, a loading elevator 50 is provided at the loading station 21 to transport the zipper pulls into the material frame 14.

[0032] Reference Figure 1 and Figure 2 The structures of the degreasing station 22, water washing station 23, and coating station 25 are basically the same, each including an independent water tank, a water pump connected to the water tank, and a spray head connected to the water pump. The water tank is located below the material frame 14, and the spray head is located above the material frame 14. The water tank at the degreasing station 22 contains a degreasing agent solution, the water tank at the water washing station 23 contains clean water, and the water tank at the coating station 25 contains a coating solution. In this embodiment, the coating solution is preferably an organosilicon coating solution. The zipper pull after degreasing has a highly alkaline surface. Considering the balance of the rotating worktable 10, the activation station and the first water washing station 23 are set as the same station. That is, a weak acid is added to the water tank at the first water washing station 23, and the alkaline substances on the surface of the zipper pull are neutralized by spraying the weak acid solution, while also removing rust stains from the product surface.

[0033] Reference Figure 1 The present invention can be equipped with a circulating hot air fan 70 on the drying station 24, or the circulating hot air fan 70 can be separated and used as a separate device, with only the air outlet of the circulating hot air fan 70 extended to the drying station 24 and facing the material frame 14 for hot air drying.

[0034] Reference Figure 1 and Figure 4 The unloading station 26 is used to empty the zipper pull of the material frame 14. The unloading station 26 is equipped with a lifting cylinder 60 for supporting the material shaft 15. A ring-shaped handguard 13 has a notch at a corresponding position on the unloading station 26 to allow the material shaft 15 to tilt downwards. The output shaft of the lifting cylinder 60 is located below this notch and is used to support the material shaft 15. When the material frame 14 and the material shaft 15 move to the unloading station 26, the material shaft 15 moves to the notch of the ring-shaped handguard 13 and is supported by the output shaft of the lifting cylinder 60. When unloading is required, the output shaft of the lifting cylinder 60 retracts, and the material shaft 15 tilts downwards, thereby emptying the zipper pull. For industrialization, a conveyor belt 80 and a storage box can also be installed on the unloading station 26 to achieve automatic collection and handling. After all the zipper pulls in the material box 14 are emptied, the output shaft of the lifting cylinder 60 extends to the same height as the ring handguard 13, so that the material shaft 15 can move smoothly to the next station after the rotating worktable 10 rotates.

[0035] Reference Figures 1 to 4 Below, taking a single operation of a single material box 14 as an example, the working steps of this utility model are as follows: S1, feeding: The zipper pull is automatically fed by the feeding elevator 50.

[0036] S2, Degreasing I, the material frame 14 moves to the first degreasing station 22 via the rotating worktable 10. The degreasing solution in the water tank of the degreasing station 22 is pumped out by the water pump and sprayed onto the zipper pull head through the spray nozzle. During spraying, the material frame 14 will rotate at a uniform speed, so that the pull head can be fully sprayed with the degreasing solution and rub against each other to achieve the purpose of removing surface oil stains.

[0037] S3, Degreasing II: The material box 14 moves to the second degreasing station 22 via the rotating worktable 10, repeating the action of the degreasing station 22. The purpose of setting up two degreasing stations 22 is that the two degreasing stations 22 can balance the cycle time and make full use of the degreasing solution. That is, when changing the degreasing solution, all the liquid in the first degreasing station 22 is drained, and then the degreasing solution in the second degreasing station 22 is poured into the water tank of the first degreasing station 22. Only new degreasing solution needs to be added to the water tank of the second degreasing station 22.

[0038] S4, washing and activation: The actions at the washing station 23 are exactly the same as those at the degreasing station 22. The only difference is that the water tank at the first washing station 23 contains water with a weak acid added to form a weak acid solution. Spraying the weak acid solution can neutralize the alkaline substances on the surface of the zipper pull and remove rust stains from the surface of the product.

[0039] S5, Water Wash II, the second water washing station 23 operates the same as the first water washing station 23, except that the water tank in the second water washing station 23 is filled with clean water.

[0040] S6-S8, Drying I to Drying III, the purpose of drying station 24 is to dry the washed zipper head. Drying is achieved by the cooperation of circulating hot air blower 70 and air outlet, and hot air is blown to achieve the purpose of drying. During the drying process, material frame 14 will be rotated at regular intervals. The purpose of setting three drying stations 24 is to balance the rhythm of rotating worktable 10.

[0041] S9, the action of the film coating station 25 is the same as that of the degreasing station 22. By spraying the silicone film coating solution on the pull head, the adhesion of the product after painting is improved. The silicone film coating can also improve the shelf life of the product. Compared with the conventional soaking film coating, spraying the film coating can save more than 50% of the consumables.

[0042] S10-S11, Drying IV to Drying V, these two drying operations are the same as Drying I to Drying III, the purpose of which is to dry the silicone film so that it can be firmly attached to the surface of the pull head.

[0043] S12, unloading: The material frame 14 moves to the unloading station 26 via the rotary worktable 10. The material shaft 15 of the material frame 14 moves to the notch of the ring guard 13 and is unloaded by the lifting cylinder 60. The unloading action has been described in detail above and will not be repeated here. The unloaded pull head can be sent out by the conveyor belt 80 or automatically stacked.

[0044] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
