[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0042] As Figures 1 to 8 shown, a waste recycling and treatment device for safety shoe production includes: a base 1, a first frame 2, a second frame 3, and a carrier 6;

[0043] The second frame 3 is arranged in the middle of the base 1, the first frame 2 is arranged above the second frame 3, and both the first frame 2 and the second frame 3 can slide along the vertical direction;

[0044] The carrier 6 is arranged between the first frame 2 and the second frame 3 and is used for carrying safety shoes;

[0045] At least two injection tubes 4 are fixedly installed on the bottom surface of the first frame 2 and are used for releasing degumming agent into the shoes; the same number of puncture tubes 5 as the injection tubes 4 are installed on the second frame 3, and the injection tubes 4 and the puncture tubes 5 correspond to each other; the puncture tubes 5 can slide along the vertical direction;

[0046] A through hole for the puncture tube 5 to pass through is provided on the bottom surface of the carrier 6;

[0047] Barbs 501 are provided at the tips of the puncture tubes 5; the bottom surface of the carrier 6 is set to be detachable;

[0048] A plurality of horizontally arranged hobs 12 are installed in the middle of the second frame 3 and are used for shredding the soles; a collection platform 7 is arranged inside the second frame 3 and is used for receiving the shredded materials.

[0049] First, the raw material of the equipment in this application can be waste safety shoes or safety shoes with defects or quality problems during production. At the initial stage of processing, it is necessary to manually or by a manipulator transfer the safety shoes to the carrier 6. At this time, lower the first frame 2 and raise the second frame 3. At this time, the puncture tube 5 of the second frame 3 pierces the sole through the through hole. In order to prevent the sole from being lifted by the puncture tube 5 during the upward movement of the puncture tube 5, the first frame 2 moves downward and presses and fixes it through the pressing plate 20 provided below. On the other hand, during the downward movement of the second frame 3, the injection tube 4 thereon also pierces the shoe upper. In some preferred embodiments, the end portions of the injection tube 4 and the puncture tube 5 can be combined inside the shoe to form a good fixation for the overall safety shoe.

[0050] Since the end of the puncture tube 5 is provided with a barb 501, after the puncture tube 5 is inserted, it will not easily come out of the sole.

[0051] In some embodiments, the water outlet holes 504 of the injection tube 4 can be provided on the side wall to inject the degumming agent into the shoe interior, thereby helping to release the glue between the sole and the shoe upper.

[0052] After the degumming is completed, pull up the shoe upper manually or by a manipulator device, etc. Due to the fixing effect of the puncture tube 5 and its barb 501, and in cooperation with the degumming agent, the sole can be separated from the shoe upper.

[0053] The carrier 6 can be set to be detachable. Thus, on the premise of not removing the sole from the puncture tube 5, first remove the carrier 6. At this time, lower the puncture tube 5. The puncture tube 5 drives the sole to approach the lower hob 12, and then the sole is rotated and shredded by the hob 12 and falls onto the lower collection platform 7.

[0054] At this time, transfer the shredded material to the processing equipment, such as the melt granulation equipment 21, etc.

[0055] A vertically arranged rack 401 is fixedly installed on the outer wall of the injection tube 4.

[0056] The tip of the puncture tube 5 is provided with a vertical counterbore. A spur gear 503 is rotatably connected to the side wall of the puncture tube 5. A scraper 502 is provided on the outer wall of the puncture tube 5. The scraper 502 is hinged to the puncture tube 5 through the spur gear 503.

[0057] The lower end of the injection tube 4 can extend into the counterbore, and during this process, the rack 401 meshes with the spur gear 503.

[0058] A water outlet hole 504 communicating with the outer wall of the puncture tube 5 is opened on the side wall of the counterbore. When the injection tube 4 extends into the counterbore, the output port on the side wall of the injection tube 4 corresponds to the water outlet hole 504.

[0059] During the downward movement of the injection tube 4, it can be inserted into the countersunk hole of the puncture tube 5. During this process, the rack 401 thereon also continuously moves downward in the countersunk hole, and then meshes with the spur gear 503 in the countersunk hole, and drives it to rotate, driving the scrapers 502 on both sides of the puncture tube 5 from the original state of being attached (without affecting puncture) to the outer wall of the puncture tube 5 to the unfolded state. After the scraper 502 is stretched, the height of the puncture tube 5 is appropriately lowered so that the scraper 502 is attached to the sole. At this time, the puncture tube 5 or the scraper 502 thereon can be rotated to pre-scrape off other components that are not desired to be recovered, such as the sponge pad on the surface of the sole.

[0060] It should be noted that the scraper 502 of this embodiment can reduce the workload of manually scraping other materials, and does not imply that the scraper 502 disclosed in this embodiment can completely remove all the cotton padding materials on the insole. The scraping area of ​​the scraper 502 is circular, which is difficult to completely conform to the shape of the sole, so some of the remaining materials may need to be manually removed. The bottom surface of the frame 1 2 is fixedly mounted with an elastic pressure plate 20.

[0061] A vertically arranged screw rod 8 is rotatably connected to the base 1 , and the screw rod 8 penetrates the frame 2 and is threadedly connected to the frame 2 .

[0062] A sprocket 16 is coaxially fixedly installed on the bottom surface of the screw rod 18, and a sprocket 15 having the same number as the puncture tube 5 is rotatably connected to the bottom surface of the frame 2 3, and the sprocket 16 and the sprocket 2 15 are connected by a transmission chain 19; a vertically arranged screw rod 2 14 is coaxially fixedly installed on the sprocket 2 15, and a mounting seat 17 is sleeved on the screw rod 2 14, and the mounting seat 17 is threadedly connected to the screw rod 2 14; the mounting seat 17 is rotatably connected to the puncture tube 5, and the mounting seat 17 can slide up and down on the frame 2 3.

[0063] When the screw rod 18 rotates, the frame 12 is driven to move up and down. The screw rod 18 also drives the sprocket 16 to rotate, and then drives the sprocket 2 15 to rotate, and then drives the screw rod 2 14 on the sprocket 2 15 to rotate. The screw rod 2 14 rotates and then drives the mounting seat 17 to move upward. The entire puncture tube 5 is driven to move upward. Then the puncture of the puncture tube 5 is implemented. That is, when the screw rod 18 rotates, it can drive the frame 12 to move up and down, and can also drive the puncture tube 5 to move up and down.

[0064] The device according to an embodiment of the present application further includes a cleaning pool 23 arranged on one side of the second rack 3 and a drum 11 arranged in the cleaning pool 23 and horizontally arranged axially; a worm 24 is coaxially and fixedly installed on the axial direction of the drum 11, the worm 24 penetrates into the second rack 3, and a worm gear 10 is coaxially and fixedly sleeved on the first screw 8, and the worm gear 10 meshes with the worm 24.

[0065] When the first rack 2 and the puncture tube 5 need to move, the drum 11 is driven to rotate along its central axis by a driver, so that the cut pieces of the sole material pre-placed therein roll and are cleaned in the cleaning pool 23. While the drum rotates, the worm 24 is driven to rotate, and then the worm gear 10 is driven to rotate, driving the first screw 8 to rotate. The first screw 8 further realizes the rotation of the first screw 8 in the above embodiment to drive the movement of the first rack 2 and the movement of the puncture tube 5. The injection tube 4 is connected to the bottom surface of the first rack 2 through a buffer spring.

[0066] A first bevel gear 9 is coaxially and fixedly sleeved in the middle of the first screw 8, and two second bevel gears 25 are respectively meshed on both sides of the first bevel gear 9; two parallel push plates 13 are slidably connected to the collection platform 7, and the puncture tube 5 is arranged between the two push plates 13; discharge ports are provided at both ends of the collection platform 7 and are communicated with the feed ports of the granulation device 21; a horizontally arranged third screw 18 is coaxially and fixedly installed on the second bevel gear 25, and the two push rods are respectively meshed with the two third screws 18.

[0067] In the initial state, the push plate 13 is in a position close to the puncture tube 5. During the process of the first screw 8 rotating to drive the puncture tube 5 to move upward, the first bevel gear 9 is also driven to rotate, thereby driving the second bevel gear 25 meshing with it to rotate, driving the third screw 18 to rotate, and then driving the push plate 13 thereon to move away from the puncture tube 5, so as to push the cut debris raw materials onto the collection platform 7 to the discharge port, and then the raw materials are transferred to the inlet of the granulation device 21. On the contrary, when the puncture tube 5 penetrates and fixes a sole at the carrier 6, after the carrier 6 is disassembled, the first screw 8 rotates to indirectly drive the puncture tube 5 to move downward. In addition, the reverse drive of the first screw 8 drives the push plate 13 to move back. When the puncture tube 5 returns to the initial state, the sole punctured by it is tightened on the hob 12 through the barb 501. At the same time, the push plate 13 also returns to the state of fitting on the puncture tube 5. In this way, after the hob 12 cuts the sole, the previous process is repeated, that is, the process of pushing the cut raw materials to the outlet of the granulation device 21.

[0068] In some embodiments, a toolbox 22 is installed on the base 1, which is convenient for manual operation.

[0069] In some other embodiments, one end of the carrier 6 close to the cleaning tank 23 is hinged to the base 1, so that after the puncture tube 5 and the injection tube 4 are detached from the carrier 6, the residual degumming liquid therein can be poured into the cleaning tank 23, so that the degumming liquid can be reused in the cleaning tank 23, thereby reducing production costs.

[0070] The equipment of the present application also includes a granulation device 21, and the bottom surface of the frame 2 is provided with a heating plate, and the heating plate can be attached to the bonding point between the upper and the sole of the safety shoe; the exhaust port of the granulation device 21 is connected to the heating plate through an air pump and an air pipe.

[0071] In some preferred embodiments, heating the joint between the upper and the sole will facilitate the debonding agent to work. In the present application, during the reuse of materials, granulation often generates high-temperature gas, which is transported to the heating plate through a compressor or other gas delivery device such as a blower. The heating plate is provided with a cavity connected to the gas, thereby making full use of the heat resources to heat the sole, making it easier to separate the sole from the upper.

[0072] In order for those skilled in the art to better understand the implementation of the present application, some details are specifically described in this embodiment. First, the present application is directed to the recycling of soles. For other material recycling, for example, the equipment of the present application needs to be combined with other equipment or operated manually, which will not be repeated in the present application. In addition, the equipment of the present application can facilitate the separation of the upper and the sole, saving labor, but the present application does not imply that the removal of the present application does not require manual participation at all. Because of the difference in material and fixing method, if the separation is not clean, it is still necessary to separate the residual impurities on the sole manually. On the other hand, since the fixing methods of the soles and uppers of different safety shoes may be different, for example, some safety shoes may involve suture connection with sutures in addition to the adhesive connection. At this time, in addition to the structure disclosed in the present application, a stitch remover in the prior art or manual cutting of the stitches may be required. In short, different scenarios may require skilled technicians to adopt other known technologies to achieve better separation.

[0073] In the description of this specification, the description with reference to the terms "one embodiment", "example", "specific example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0074] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
