Description

Technical Field

[0001] This invention relates to the field of shoe drying equipment, and more specifically, to a shoe drying equipment for shoe processing and production and its usage method. Background Technology

[0002] During the shoe manufacturing process, the sole and upper are bonded together with adhesive. To ensure the adhesive solidifies quickly and strengthens the bond, the shoes need to be dried. Currently, most manufacturers use tunnel ovens for this process. The tunnel oven is connected to the output end of the adhesive production line, and the pre-processed shoes are sent directly to the input end of the tunnel oven. The shoes then enter the tunnel oven via a conveyor belt and are dried by hot air.

[0003] However, the above-mentioned processing method, since the shoes are directly output from the bonding production line, most of the shoe tongue is located inside the shoe, below the upper. This will block the opening and shoelace holes of the shoe to a certain extent, affecting the entry of hot air into the shoe. Even if hot air is sprayed into the shoe, it will not turn the shoe tongue outward and will remain in a blocked position. The space inside the shoe is significantly limited, and the hot air entering the shoe is not easy to be discharged and flow out, thus affecting the overall drying effect and efficiency, and also hindering the discharge of waste gas. Therefore, it needs to be improved. Summary of the Invention

[0033] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] like Figure 1 , Figure 2 As shown in the figure, a specific embodiment of the present invention discloses a drying equipment for shoe processing and production and its usage method, including a tunnel oven 100, an arranging conveyor 200, a transfer device 300, and a tongue-pressing device 400; the arranging conveyor 200 is located on one side of the tunnel oven 100 and is used for arranging and conveying shoes; the tongue-pressing device 400 is located at the output end of the arranging conveyor 200 and is used to push the shoe tongue so that the shoe tongue is located on the inside of the shoe surface; the transfer device 300 is located on the outside of the input end of the tunnel oven 100 and spans across the top of the arranging conveyor 200; the transfer device is used to clamp the shoe tongue, turn the shoe tongue outwards onto the outside of the shoe surface, and transfer the shoe to the conveying structure of the tunnel oven by suspending the shoe tongue.

[0035] The aforementioned shoe processing and production drying equipment includes a tunnel oven, an arranging conveyor, a transfer device, and a tongue-pressing device; the arranging conveyor is located on one side of the tunnel oven and is used to arrange and convey shoes so that they are tightly arranged so that they can cooperate with the tongue-pressing device and the transfer device for subsequent alignment and handling.

[0036] The tongue-pressing device is located at the output end of the arranging and conveying device. The tongue-pressing device is used to push the shoe tongue, so that the outward-turned shoe tongue is also returned to the inside, so that the shoe tongue is located on the inside of the shoe surface, providing basic conditions for subsequent clamping and facilitating the clamping of the shoe tongue.

[0037] The transfer device is located on the outside of the input end of the tunnel oven and spans across the top of the conveyor system. The transfer device is used to clamp the shoe tongue, turn the shoe tongue outwards onto the outside of the shoe surface, and transfer the shoe to the conveyor structure of the tunnel oven by suspending the shoe tongue. This keeps the shoe tongue on the outside of the shoe surface, widens the opening of the shoe, facilitates the entry of hot air and the flow of hot air, improves drying efficiency and quality, and also accelerates the discharge of exhaust gas.

[0038] It should be noted that the electrical control box, tunnel oven, conveying device, transfer device, and tongue pressing device are all electrically connected to the electrical control box, which enables coordinated operation and cooperation between various electrical instruments. The electrical control box and tunnel oven are common electrical equipment that can be purchased and used on the market. Their specific structures will not be described in detail.

[0039] Furthermore, such as Figure 3 As shown, the arranging and conveying device 200 includes a first support groove 210, a first conveyor belt 220, and a first motor. The first conveyor belt 220 is installed inside the first support groove 210 by multiple support rollers, and the upper surface of the first conveyor belt 220 is lower than the opening of the first support groove 210. The first conveyor belt is driven to rotate by the first motor, and the two sides of the first conveyor belt 220 slide against the groove wall of the first support groove 210. The two groove walls of the first support groove limit the two sides of the first conveyor belt so that the shoes can be arranged and conveyed, and the shoes can be prevented from running off-center.

[0040] The tongue depressor 400 is installed on the wall of the output end of the first support groove 210, and the transfer device 300 is located on the side of the tongue depressor 400 near the center of the first conveyor belt 220. An adjustment device 500 is provided between the tongue depressor 400 and the transfer device 300. The adjustment device is used to clamp and align the shoes at the transfer station. The adjustment device makes the shoes more accurately aligned with the center part so as to align with the tongue depressor and the transfer device. In addition, the adjustment device can also clamp and fix the shoes. Especially during the process of turning the tongue out, it is necessary to clamp and fix the two sides of the bottom of the shoe through the adjustment device, so that only the tongue is turned outward without lifting the entire shoe.

[0041] Furthermore, such as Figure 3As shown, the adjustment device 500 includes two symmetrically arranged first cylinders 510. A first push plate 520 is fixedly installed at the end of the piston rod of the first cylinder 510. The two walls of the first support groove 210 are respectively provided with first through holes 230. The first cylinders 510 are installed on the outside of the first through holes 230 by bolts. The first push plate is placed at the first through hole and can be retracted to be flush with the groove wall of the first support groove. The bottom end of the first push plate 520 is flush with the upper surface of the first conveyor belt 220. The adjustment device is simple and convenient for production and assembly. The symmetrical structure can better adjust the shoe to the center and also facilitates a stable clamping and fixing, preventing the shoe from coming loose when the tongue is turned out.

[0042] Furthermore, such as Figure 9 As shown, the tongue-pressing device 400 includes a support frame 410, a second cylinder 420, and a pushing member 430. The support frame 410 is bolted between the two walls of the first support groove 210. The pushing member 430 is slidably disposed at the support frame 410. The second cylinder 420 is used to drive the pushing member 430 to move along the length of the first conveyor belt 220. A tongue-pressing device 431 is fixedly provided at the top of one end of the pushing member 430 near the transfer device 300. The tongue-pressing device 431 is positioned corresponding to the center of the first conveyor belt 220, and its height is adapted to the height of the top of the shoe toe. The position of the tongue-pressing device 431 is as follows: Corresponding to the center position of the shoe, when the pressure tongue is extended, the first conveyor belt drives the shoes to be arranged and conveyed. During the process of the shoes moving towards the output end, the pressure tongue is equivalent to pushing against the top of the shoe toe towards the shoe tongue. The shoe tongue located inside the shoe is not affected, while the shoe tongue in the outward position is pushed back into the shoe opening under the action of the push, so that the shoe tongue is retracted to the inside of the shoe surface, providing the basic conditions for subsequent clamping and transfer. The pushing component is driven by the second cylinder. When it is necessary to flip out the shoe tongue and transfer the shoes, the pressure tongue needs to be retracted to prevent affecting the operation of other structures.

[0043] Furthermore, the pusher includes a rectangular frame, with a pressure tongue fixedly mounted on the top of one end of the frame near the transfer device. A second push plate is fixedly mounted on the side wall of the other end of the frame. A threaded post is fixedly mounted on the end of the piston rod of the second cylinder, penetrating the second push plate. A nut is mounted on the end of the threaded post, so that the second push plate is fixed to the end of the piston rod of the second cylinder, ensuring that the second cylinder can drive the pusher to move back and forth. The assembly structure facilitates the processing and production of each structural component, and also facilitates the disassembly and replacement of parts, making it convenient to use.

[0044] Furthermore, the end of the tongue furthest from the frame has a narrowed structure, and the edge of the tongue is chamfered, which makes it easy to push the tongue towards the shoe tongue, so as to push the exposed shoe tongue back under the shoe surface and prevent scratches on the outer wall of the shoe.

[0045] Furthermore, when the depressor 431 extends to the preset position, the bottom of the pusher 430 extends 1cm to 1.5cm beyond the end face of the support frame 410; the end face of the frame extends 1cm to 1.5cm outward as a support limit for the toe of the shoe. When the shoe is subsequently moved, the pusher retracts inward, and a gap is created between the shoe and the support frame to allow for lifting and moving of the shoe.

[0046] Furthermore, such as Figure 4 , Figure 5 As shown, the transfer device 300 includes a gantry frame 310, a moving structure 600, and a clamping structure 700. The gantry frame 310 spans above the arranging conveyor 200, and the moving structure 600 is mounted on the gantry frame 310. The moving structure 600 is used to drive the clamping structure 700 to move in multiple directions. The moving structure 600 drives the clamping structure 700 to move upward, which can turn the shoe tongue out to the outside of the shoe upper; it can also lift the entire shoe upward by clamping the shoe tongue. The moving structure 600 also drives the clamping structure 700 to move towards the tunnel furnace 100, thereby transferring the shoe from the arranging conveyor 200 to the tunnel furnace 100. The steps are as follows: the transfer structure drives the clamping structure to descend and extend into the shoe, then moves towards the shoe tongue and clamps the shoe tongue; then it drives the clamping structure to rise, turning the shoe tongue out of the shoe; then it lifts the entire shoe upward by clamping the shoe tongue, and then moves it horizontally to the conveyor belt of the tunnel furnace.

[0047] Furthermore, such as Figure 5 As shown, the moving structure 600 includes a first linear slide 610, a second linear slide 620, a support frame 630, a pusher frame 640, and a third cylinder 650. The first linear slide 610 is mounted on the beam of the gantry 310. The support frame 630 is mounted on the slider of the first linear slide 610. The pusher frame 640 is slidably mounted on the support frame 630. The third cylinder 650 is mounted on the support frame 630 and is used to drive the pusher frame 640 to move along the length of the first conveyor belt 220. The second linear slide 620 is vertically mounted on the pusher frame 640, and the clamping structure 700 is mounted on the slider of the second linear slide 620.

[0048] With the cooperation of the above structures, the second linear slide 620 is used to drive the clamping structure 700 to move vertically, the third cylinder 650 is used to drive the clamping structure 700 to move along the length direction of the first conveyor belt 220, and the first linear slide 610 is used to drive the clamping structure 700 to move along the width direction of the first conveyor belt 220. The overall structure is compact and effectively reduces the space occupied.

[0049] Furthermore, such as Figures 4 to 7As shown, the support frame 630 includes a base 631, a first upright plate 632 fixedly disposed on the top surface of the base 631, the first upright plate 632 being bolted to the slider of the first linear slide 610; the top surface of the base 631 is provided with a first slot 633, and a first locking strip 634 is fixedly disposed at the bottom of the slot 633; ​​the base 631 is provided with a second through hole, a third cylinder 650 is installed at the second through hole, and a third push plate is installed at the end of the piston rod of the third cylinder 650; the push frame 640 includes a slide 641, a second upright plate 642 fixedly disposed on the top surface of the slide 641, the slide 641 being slidably disposed at the first slot 633, and slidably engaging with the first locking strip 634; a fourth push plate 643 is provided at the bottom of the end of the slide 641 away from the base 631, and the fourth push plate is fixedly connected to the third push plate by bolts; the second linear slide 620 is mounted on the second upright plate 642;

[0050] The support frame and the push frame are slidably engaged with the slide block via the first locking strip, which restricts the push frame to move along the extension direction of the first locking strip, allowing the clamping part to be moved towards the shoe tongue for easy clamping and fixing. Furthermore, through the cooperation of the slide block with the first locking groove and the first locking strip, the two sides of the slide block are restricted by the first locking groove and the first locking strip, which facilitates the transfer and distribution of force, ensuring that the entire push frame can move along the length direction of the first linear slide block along with the support frame.

[0051] Furthermore, the slide groove of the slide block is a T-shaped groove or a dovetail groove structure. The shape of the first locking strip is adapted to the shape of the slide groove. The slide block is slidably locked at the first locking strip, which not only does not affect normal movement, but also effectively prevents the slide block from detaching.

[0052] Furthermore, a first pressure plate is fixedly installed on the top of the first upright plate away from the gantry wall, and a second pressure plate is fixedly installed on the top of the second upright plate away from the gantry wall. The top surface of the second pressure plate slides against the bottom surface of the first pressure plate. This further restricts the push frame in the vertical direction, strengthens the overall connection and cooperation, and also enhances the support force for the second linear slide. The bottom surface of the second pressure plate is provided with a second slot, and the top surface of the first pressure plate is provided with a corresponding second locking strip. The second locking strip slides into the second slot, which can further restrict the movement of the push frame, making it move only along the length direction of the first locking strip. It can also restrict the movement of both sides, facilitating the transmission of force and allowing the push frame to move with the support frame.

[0053] Furthermore, such as Figure 8As shown, the clamping structure 700 includes a bracket 710, a sleeve 720, an electric push rod 730, and a fifth push plate 740. A support plate 721 extending outwards is fixed to the outer bottom of the sleeve 720. The sleeve 720 is bolted to the bottom of the bracket 710, and the top of the bracket 710 is mounted on the slider of the second linear slide 620. The electric push rod 730 is installed inside the sleeve 720. A strip-shaped opening 722 is provided on the side wall of the sleeve 720 near the support plate 721, with the top of the opening open. The fifth push plate... The fifth push plate 740 is slidably positioned at the slot 722. The fifth push plate 740 is installed at the piston rod end of the electric push rod 730. The electric push rod drives the fifth push plate to move. When the fifth push plate moves downward, it can form a clamping part with the support plate, which can effectively clamp the shoe tongue. When the fifth push plate moves upward, it leaves a larger gap with the support plate, which facilitates the clamping opening and the shoe tongue to be locked together, which is convenient for subsequent clamping and fixing. In addition, the bottom of the clamping structure is a cylindrical structure, which can be easily inserted into the shoe and facilitates entry and exit from the shoe opening.

[0054] Furthermore, the fifth push plate includes a circular plate, a protrusion is fixedly provided on one side of the circular plate, and a clamping plate is fixedly provided at the end of the protrusion. The circular plate slides against the inner wall of the sleeve; the protrusion slides along the side wall of the strip opening, effectively limiting the movement of the fifth push plate, thereby forming an effective clamping between the fifth push plate and the support plate.

[0055] Furthermore, the bracket has an L-shaped structure, with a mating plate fixedly installed at the bottom of the bracket. The mating plate has a third through hole, and the outer wall of the sleeve has a corresponding threaded hole. The mating plate abuts against the outer wall of the sleeve and is fixedly connected by bolts. The bottom of the bracket covers the top of the sleeve, and the top of the electric push rod is fixedly connected to the bottom of the bracket by bolts. The whole adopts an assembly structure, which facilitates the processing and production of each structural component, and also facilitates assembly and disassembly and replacement of structural components. The design of the bracket also allows sufficient space between the sleeve and the second linear slide, so that the downward-moving sleeve can be better inserted into the shoe, which is convenient for actual operation and use.

[0056] Furthermore, such as Figure 2 , Figure 5 As shown, a baffle 800 is installed on the bottom surface of the base 631; a slot 240 is provided between the two walls of the first support groove 210, the bottom surface of the slot 240 is flush with the upper surface of the first conveyor belt 220, and the thickness of the slot 240 is adapted to the thickness of the baffle 800.

[0057] A notch 810 is provided on the side of the baffle 800 that is offset from the tunnel furnace 100. The width of the notch 810 is adapted to the distance between the two outer walls of the first support groove 210. When the clamping structure moves to the position corresponding to the pressure tongue, the notch is located on the outside of the first support groove, and the baffle is placed between the first and second shoes to separate the first shoe. When the moving structure moves the clamping structure towards the tunnel furnace to move the shoes, it moves the baffle, causing the notch to move to the inside of the first support groove, so that the subsequent shoes are pushed forward and conveyed. By setting the baffle to cut off the shoes, the first shoe at the head is separated independently, so that the subsequent steps such as flipping out the shoe tongue and transferring can be carried out. Moreover, the baffle is installed on the support frame base. As the transfer structure moves, the position of the baffle is adjusted and changed, which not only achieves blocking and separation, but also makes it easy for the subsequent shoes to pass through the notch and move to the first position.

[0058] Furthermore, the side of the gate closest to the tunnel furnace has a chamfer to form a narrow section, which makes it easier for the baffle to be inserted between two shoes to form a partition.

[0059] Furthermore, a guide groove is fixedly provided on the outer side of the bayonet, and the baffle slides along the guide groove, which can further enhance the restriction and support of the baffle. By increasing the contact area on both sides, the overall support of the baffle is strengthened, preventing the shoes that are subsequently arranged and conveyed from squeezing and deforming the baffle. It can also extend the guiding restriction of the baffle, and maintain the sliding contact between the baffle and the bayonet during the transfer and placement of shoes.

[0060] More specifically, the present invention also provides a method for using a drying device for shoe processing and production, comprising the following steps:

[0061] In the initial state, the notch of the baffle is located inside the first support groove and corresponds to the two groove walls of the first support groove; the tongue of the tongue-pressing device is in the extended state, and the end face of the frame extends outward by a preset length;
