[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figures 1 to 8 As shown, a waste recycling and processing equipment for safety shoe production includes: a base 1, a frame 1 2, a frame 2 3 and a carrier 6;

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

[0044] The carrier 6 is disposed between the frame 1 2 and the frame 2 3 and is used to carry safety shoes;

[0045] At least two injection tubes 4 are fixedly mounted on the bottom surface of the frame 1 2, which are used to release the adhesive remover into the shoe; the frame 2 3 is mounted with the same number of puncture tubes 5 as the injection tubes 4, and the injection tubes 4 correspond to the puncture tubes 5; the puncture tubes 5 can slide in the vertical direction;

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

[0047] The tip of the puncture tube 5 is provided with a barb 501; the bottom surface of the carrier 6 is provided to be detachable;

[0048] A plurality of horizontally arranged roller cutters 12 are installed in the middle of the frame 2 3 for shredding the soles; a collecting platform 7 is arranged inside the frame 2 3 for receiving the shredded materials.

[0049] First of all, the raw material of the equipment of the present application can be waste safety shoes, or safety shoes that have defects or quality problems during production. In the initial stage of processing, it is necessary to transfer the safety shoes to the carrier 6 manually or by a robot. At this time, the rack 1 2 is moved down and the rack 2 3 is moved up. At this time, the puncture tube 5 of the rack 2 3 pierces the sole through the through hole. In order to prevent the sole from being lifted up by the puncture tube 5 during the upward movement of the puncture tube 5, the rack 1 2 is moved down and is pressed and fixed by the pressure plate 20 arranged below. On the other hand, during the downward movement of the rack 2 3, the injection tube 4 thereon also pierces the upper. In some preferred embodiments, the ends of the injection tube 4 and the puncture tube 5 can be combined in the shoe to form a good fixation for the safety shoe as a whole.

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

[0051] In some embodiments, the water outlet hole 504 of the injection tube 4 can be set on the side wall to inject the glue remover into the inside of the shoe, thereby helping to release the glue between the sole and the upper.

[0052] When the glue removal is completed, the shoe upper is pulled upwards manually or by a robot device, etc. Due to the fixing effect of the puncture tube 5 and its barb 501, the sole can be separated from the shoe upper in combination with the glue removal agent.

[0053] The carrier 6 can be detachable, so that the carrier 6 can be removed without removing the sole from the puncture tube 5. At this time, the puncture tube 5 is moved down, and the puncture tube 5 drives the sole to approach the roller 12 below, so that the sole is rotated and shredded by the roller 12 and falls onto the collection platform 7 below.

[0054] At this point, the shredded material is transferred to a processing device, such as a melt granulation device 21 or the like.

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

[0056] The tip of the puncture tube 5 is provided with a vertical countersunk hole, 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, and 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 be inserted into the counterbore, and in the process, the rack 401 is meshed with the spur gear 503;

[0058] A water outlet hole 504 penetrating to the outer wall of the puncture tube 5 is provided on the side wall of the sink hole. When the injection tube 4 is inserted into the sink hole, the output port of 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 equipment of the embodiment of the present application also includes a cleaning pool 23 arranged on one side of the frame 23 and a roller 11 arranged in the cleaning pool 23 and axially horizontally arranged; the roller 11 is axially coaxially fixedly installed with a worm 24, and the worm 24 penetrates into the frame 23, and the screw 18 is coaxially fixedly sleeved with a worm wheel 10, and the worm wheel 10 is meshed with the worm 24.

[0065] When the rack 2 and the puncture tube 5 need to move, the driver drives the roller 11 to rotate along its axis, so that the shredded pieces of the sole material placed therein are rolled and clear in the cleaning tank 23. While the roller is rotating, the worm 24 is driven to rotate, and then the worm wheel 10 is driven to rotate, driving the screw 8 to rotate, and the screw 8 realizes the rotation of the screw 8 in the above embodiment to drive the movement of the rack 2 and the puncture tube 5. The injection tube 4 is connected to the bottom surface of the rack 2 by a buffer spring.

[0066] A bevel gear 19 is fixedly mounted on the middle part of the screw 8, and bevel gears 25 are respectively meshed on both sides of the bevel gear 19; two parallel push plates 13 are slidably connected to the collecting platform 7, and the puncture tube 5 is arranged between the two push plates 13; both ends of the collecting platform 7 are provided with discharge ports, which are connected to the feed port of the granulating equipment 21; a horizontally arranged screw 3 18 is coaxially fixedly mounted on the bevel gear 25, and the two push rods are respectively meshed with the two screws 3 18.

[0067] In the initial state, the push plate 13 is close to the puncture tube 5. When the screw rod 18 rotates to drive the puncture tube 5 upward, it also drives the bevel gear 19 to rotate, thereby driving the bevel gear 25 meshing with it to rotate, driving the screw rod 3 18 to rotate, thereby driving the push plate 13 thereon to move away from the puncture tube 5, thereby pushing the debris material cut on the collection platform 7 to the discharge port, and then transferring the material 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 screw rod 18 rotates to indirectly drive the puncture tube 5 downward. In addition, the reverse drive of the screw rod 18 in turn drives the push plate 13 to return. When the puncture tube 5 returns to the initial state, the sole punctured by it is tightened on the roller 12 through the barb 501. At the same time, the push plate 13 also returns to the state of being attached to the puncture tube 5. In this way, after the roller cutter 12 shreds the sole, the previous process is repeated again, that is, the process of cutting the raw materials and pushing them to the outlet of the granulation device 21.

[0068] In some embodiments, a tool box 22 is installed on the base 1 to facilitate 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 above shows and describes 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 to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
