Description

Technical Field

[0001] This utility model relates to the field of shoe last processing technology, specifically to a shoe last processing equipment. Background Technology

[0002] In the field of shoe last processing technology, the shoe last is a key mold for shoe forming, and its surface treatment quality directly affects the comfort and appearance of the shoe. At present, there are many problems that need to be solved in the spraying process of existing shoe last processing equipment.

[0003] However, in practical applications, most of the existing shoe last spraying processes are carried out by workers using their hands to spray, which is not only inefficient, but also the sprayed pigments are harmful to the body. Some mechanized spraying equipment usually has the defects of single spraying angle and limited coverage, making it difficult to spray the shoe last surface evenly from multiple directions, resulting in uneven coating on the shoe last surface, which affects the processing quality and efficiency.

[0004] According to the description in the patent application published on the Internet, a rotary spraying device for shoe last processing (authorization announcement number: CN212820565U) includes a "U-shaped frame, shoe last body" etc., to realize the spraying work.

[0005] Regarding the above description, the applicant believes the following issues exist:

[0006] This rotary spraying device for shoe last processing utilizes a U-shaped frame and the shoe last body to perform spraying operations. While the device sprays the shoe last body, the spraying only occurs on one side of the top of the shoe last body, and the angle cannot be adjusted. Although it can rotate the shoe last body, the heel area is also not sprayed, affecting the overall spraying process. Therefore, improvements to this device are needed. Utility Model Content

[0007] The purpose of this invention is to provide a shoe last processing device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a shoe last processing equipment, including a base, a protective box fixedly connected to the top of the base, a sealing door rotatably connected to the front side of the protective box, a spraying mechanism fixedly connected to the top of the protective box, and a fixing mechanism provided inside the protective box;

[0009] The spraying mechanism includes a liquid storage tank, which is fixedly connected to the top of a protective box. A delivery pipe is fixedly connected to the right side of the liquid storage tank. A pump body is fixedly connected to the periphery of the delivery pipe. A distributor is fixedly connected to the bottom of the delivery pipe. A delivery ring is fixedly connected to the periphery of the distributor. A first nozzle is fixedly connected to the bottom of the delivery ring. A first connecting pipe is fixedly connected to the left side of the delivery ring. A connecting frame is fixedly connected to the periphery of the first connecting pipe. A second nozzle is fixedly connected to the bottom of the first connecting pipe. A second connecting pipe is fixedly connected to the bottom of the distributor. A third nozzle is fixedly connected to the bottom periphery of the second connecting pipe.

[0010] Preferably, the sealed door has an observation port inside, and the observation port is equipped with tempered glass. The pump body is fixedly connected to the top of the protective box, so as to facilitate observation of the spraying situation inside the protective box through the observation port.

[0011] Preferably, the conveying pipe is fixedly connected inside the protective box, and the connecting frame is fixedly connected to the top of the protective box, so as to ensure the stability of the first connecting pipe and the conveying ring through the connecting frame.

[0012] Preferably, the conveying ring, the distributor, the first connecting pipe, the first nozzle, the connecting frame, the second nozzle, the second connecting pipe, and the third nozzle are all located inside the protective box. The second nozzle and the third nozzle are respectively inclined to facilitate the spraying of the shoe last body surface through the three nozzles.

[0013] Preferably, the first connecting pipe, the connecting frame, and the second spray head are provided in two sets, and are symmetrically distributed on the left and right sides of the conveying ring, so as to improve the comprehensiveness of spraying by setting two sets.

[0014] Preferably, the fixing mechanism includes a servo motor, which is fixedly connected to the bottom of the protective box. A rotating shaft is fixedly connected to the top of the servo motor and rotatably connected to the inside of the protective box. A rotating platform is fixedly connected to the top of the rotating shaft, and a mounting bracket is inserted into the top of the rotating platform. A shoe last body is inserted into the top of the mounting bracket, and a limit shaft is threadedly connected inside the mounting bracket.

[0015] Preferably, the limiting shaft passes through the interior of the rotating table, and the shoe last body is located at the bottom of the first nozzle and inside the second and third nozzles. This facilitates the stability of the mounting frame through the limiting shaft and also makes it easy to replace the matching mounting frame according to the last holes inside the shoe last body of different sizes.

[0016] Compared with the prior art, this utility model provides a shoe last processing equipment, which has the following beneficial effects:

[0017] The shoe last processing equipment features a spraying mechanism. When spraying is required during the processing of the shoe last, the storage tank, in conjunction with a pump and delivery pipe, transports the coating to a distributor. The coating then passes through a delivery ring, a first connecting pipe, and a second connecting pipe, where it is sprayed by a first, second, and third nozzle. The first nozzle at the bottom of the delivery ring sprays the top of the shoe last. The second and third nozzles at the bottom of the first and second connecting pipes are angled, with two symmetrically distributed sets of second nozzles allowing for all-around spraying of the shoe last's sides from different angles. This ensures uniform coating across all parts of the shoe last surface, significantly improving spraying quality and efficiency. The protective box provides a closed space for shoe last processing, effectively preventing coating splashes. An observation port inside the sealed door is fitted with tempered glass, allowing operators to observe the internal processing without opening the sealed door.

[0018] The shoe last processing equipment, through its fixed mechanism, allows for the selection of a matching mounting frame based on the size of the shoe last body and the internal last hole dimensions when spraying is required. The mounting frame is then inserted into the top of the rotating table and fixed by a limiting shaft. Simultaneously, the shoe last body is inserted into the top of the mounting frame, ensuring the stability of the shoe last body. Multiple mounting frames are available, allowing for the simultaneous installation of multiple shoe last bodies, thus improving spraying efficiency. A servo motor drives the rotating shaft and rotating table, enabling the shoe last body to rotate during processing. Combined with multi-directional spray nozzles, this allows for spraying without blind spots. Attached Figure Description

[0028] This utility model provides the following technical solution: Example 1

[0029] Please see Figure 1-5 This utility model provides a technical solution: a shoe last processing equipment, including a base 1, a protective box 2 fixedly connected to the top of the base 1, a sealing door 5 rotatably connected to the front side of the protective box 2, a spraying mechanism 3 fixedly connected to the top of the protective box 2, and a fixing mechanism 4 provided inside the protective box 2.

[0030] The spraying mechanism 3 includes a liquid storage tank 31, which is fixedly connected to the top of the protective box 2. A delivery pipe 33 is fixedly connected to the right side of the liquid storage tank 31. A pump body 32 is fixedly connected to the periphery of the delivery pipe 33. A distributor 34 is fixedly connected to the bottom of the delivery pipe 33. A delivery ring 35 is fixedly connected to the periphery of the distributor 34. A first nozzle 36 is fixedly connected to the bottom of the delivery ring 35. A first connecting pipe 38 is fixedly connected to the left side of the delivery ring 35. A connecting frame 37 is fixedly connected to the periphery of the first connecting pipe 38. A second nozzle 39 is fixedly connected to the bottom of the first connecting pipe 38. A second connecting pipe 391 is fixedly connected to the bottom of the distributor 34. A third nozzle 392 is fixedly connected to the periphery of the bottom of the second connecting pipe 391.

[0031] An observation port is provided inside the sealed door 5, and tempered glass is installed inside the observation port. The pump body 32 is fixedly connected to the top of the protective box 2, so that the spraying situation inside the protective box 2 can be observed through the observation port.

[0032] The conveying pipe 33 is fixedly connected to the inside of the protective box 2, and the connecting frame 37 is fixedly connected to the top of the protective box 2, so as to ensure the stability of the first connecting pipe 38 and the conveying ring 35 through the connecting frame 37.

[0033] The conveying ring 35, the distributor 34, the first connecting pipe 38, the first nozzle 36, the connecting frame 37, the second nozzle 39, the second connecting pipe 391, and the third nozzle 392 are all located inside the protective box 2. The second nozzle 39 and the third nozzle 392 are inclined to facilitate spraying the surface of the shoe last body 46 through the three nozzles. The first connecting pipe 38, the connecting frame 37, and the second nozzle 39 are provided in two sets and are symmetrically distributed on the left and right sides of the conveying ring 35. By setting two sets, the comprehensiveness of the spraying can be improved. Example 2

[0034] Please see Figure 1-5 Furthermore, based on Embodiment 1, the fixing mechanism 4 includes a servo motor 41, which is fixedly connected to the bottom of the protective box 2. A rotating shaft 42 is fixedly connected to the top of the servo motor 41. The rotating shaft 42 is rotatably connected to the inside of the protective box 2. A rotating platform 43 is fixedly connected to the top of the rotating shaft 42. A mounting bracket 44 is inserted into the top of the rotating platform 43. A shoe last body 46 is inserted into the top of the mounting bracket 44. A limit shaft 45 is threadedly connected inside the mounting bracket 44.

[0035] The limiting shaft 45 passes through the inside of the rotating table 43. The shoe last body 46 is located at the bottom of the first nozzle 36 and inside the second nozzle 39 and the third nozzle 392. This makes it easy to ensure the stability of the mounting bracket 44 through the limiting shaft 45, and at the same time, it is easy to replace the matching mounting bracket 44 according to the last holes inside the shoe last body 46 of different sizes.

[0036] In actual operation, when this device is used, when the shoe last body 46 needs to be sprayed during the processing, firstly, according to the different sizes of the shoe last body 46 and the size of the internal last holes, a matching mounting bracket 44 is selected, and the mounting bracket 44 is inserted into the top of the rotating table 43. The mounting bracket 44 is fixed by the limiting shaft 45, and the shoe last body 46 is inserted into the top of the mounting bracket 44. This ensures the stability of the shoe last body 46. Moreover, there are multiple mounting brackets 44, so multiple shoe last bodies 46 can be installed at one time, which improves the efficiency of spraying.

[0037] After fixing, the sealing door 5 is closed. The liquid storage tank 31, in cooperation with the pump body 32 and the delivery pipe 33, delivers the coating to the distributor 34, and then through the delivery ring 35, the first connecting pipe 38 and the second connecting pipe 391, and is sprayed by the first nozzle 36, the second nozzle 39 and the third nozzle 392. The first nozzle 36 at the bottom of the delivery ring 35 can spray the top of the shoe last body 46. The second nozzle 39 at the bottom of the first connecting pipe 38 and the third nozzle 392 at the bottom of the second connecting pipe 391 are inclined, and the second nozzle 39 is set in two sets of symmetrical distribution, which can spray the side of the shoe last from different angles in all directions, ensuring that all parts of the shoe last surface are evenly covered with coating, which greatly improves the quality and efficiency of spraying. The protective box 2 provides a closed space for shoe last processing, effectively preventing coating splashing. The observation port inside the sealing door 5 is equipped with tempered glass, so that the operator can observe the internal processing without opening the sealing door 5.

[0038] During the spraying process, the servo motor 41 can drive the rotating shaft 42 and the rotating table 43 to rotate, so that the shoe last body 46 can rotate during the processing. With the multi-directional spray nozzle, spraying without dead angles can be achieved, improving the efficiency and uniformity of spraying. After the spraying is completed, the shoe last body 46 can be taken out for subsequent drying and processing operations.
