[0002] In the shoe manufacturing process, shoelace cutting is an important process.

DETAILED DESCRIPTION

[0018] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0019] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0020] like Figures 1 to 5As shown, a shoelace fixed-length cutting device for shoe manufacturing provided by an embodiment of the present invention comprises a feed tray 1, a cutting mechanism and a wire pulling mechanism, wherein the feed tray 1 and the wire pulling mechanism are respectively located on both sides of the cutting mechanism, a knife seat 2 is installed at the movable end of the cutting mechanism, and a cutting knife 3 is fixedly connected to the knife seat 2, and further comprises: a first guide rail 4 arranged transversely, the first guide rail 4 is located on the side of the cutting mechanism away from the wire pulling mechanism, a sliding seat 5 is slidably connected to the first guide rail 4, and the sliding seat 5 is connected to the first guide rail 4 through a first elastic member 6; an ear plate 7 is fixedly connected to the sliding seat 5, and the ear plate 7 is rotated Two squeezing rollers 8 are connected, and the ends of the two squeezing rollers 8 are meshed through a gear 9; a clamping piece is connected to the ear plate 7 through a second elastic piece 10, and the clamping piece can be clamped in the tooth groove of the gear 9; and a push rod 12 is fixedly connected to the end of the first guide rail 4, and when the sliding seat 5 approaches the push rod 12, the push rod 12 can squeeze the clamping piece to disengage the clamping piece from the tooth groove of the gear 9; a vertical rod 13 is provided on the sliding seat 5, and an oblique rod 14 is fixedly connected to the end of the vertical rod 13 away from the sliding seat 5, and the knife seat 2 can push the sliding seat 5 to slide along the first guide rail 4 by squeezing the oblique rod 14.

[0021] With this setting, the specific usage process is: In the first step, the wire pulling mechanism clamps the end of the shoelace rope; In the second step, the knife seat 2 descends, and at the same time, the knife seat 2 pushes the sliding seat 5 to move away from the wire pulling mechanism through the inclined rod 14 (in this process, the gear 9 is stuck by the clamping piece, and the squeezing roller 8 can firmly clamp the shoelace rope). The knife seat 2 descends all the way to the connection between the inclined rod 14 and the vertical rod 13. At this time, the sliding seat 5 is close to the top rod 12, and the top rod 12 squeezes the clamping piece, so that the clamping piece and the tooth groove of the gear 9 are disengaged, and the squeezing roller 8 can rotate at this time; In the third step, the pulling mechanism pulls the shoelace rope to the side away from the cutting mechanism to a preset position (determined by the length to be cut); Step 4: The knife seat 2 continues to descend, so that the cutting knife 3 cuts the shoelace. In this process, the knife seat 2 descends along the vertical rod 13, so the position of the sliding seat 5 remains unchanged; Step 5. After the cutting is completed, the wire pulling mechanism is reset, and the knife seat 2 is reset upward. During the reset of the knife seat 2, the sliding seat 5 is automatically reset under the push of the first elastic member 6. In addition, the first step of the reset of the sliding seat 5 is that the clamping member is no longer squeezed by the top rod 12, so the clamping member is again clamped on the tooth groove of the gear 9. Therefore, during the reset of the sliding seat 5, the squeezing roller 8 cannot rotate, so the shoelace rope can be clamped and the rope end of the shoelace rope can be pulled to one side of the wire pulling mechanism. Since there is a certain distance between the squeezing roller 8 and the cutting knife 3 during cutting, a part of the shoelace rope is exposed, so the wire pulling mechanism can clamp the rope end of the shoelace rope that is exposed.

[0022] This setting has the following effects: First, the cut rope ends can be sent to the wire pulling mechanism, so that continuous cutting can be achieved; Second, the whole process does not affect or hinder the cutting of the cutting knife 3; Third, when the wire pulling mechanism is pulling the wire, the squeezing roller 8 is automatically unlocked so that the wire can be pulled. When the sliding seat 5 is reset and the rope end is sent to the wire pulling mechanism, the squeezing roller 8 is automatically locked, thereby clamping the rope end and sending it to the position of the wire pulling mechanism; Fourth, during the entire process of delivering the rope head, no additional control mechanism is required for control, and no additional driving mechanism is required to provide power, and the entire process is automatically consistent with the cutting action.

[0023] Specifically, the cutting mechanism includes a carrier frame 15, a hydraulic cylinder 16 is fixedly connected to the upper side of the carrier frame 15, the telescopic end of the hydraulic cylinder 16 extends to the lower side of the carrier frame 15, the lower end of the telescopic end of the hydraulic cylinder 16 is fixedly connected to the knife seat 2, and a cutting table 17 is provided below the cutting knife 3, and a gap is provided between the cutting table 17 and the lower end of the cutting knife 3. The setting of the gap allows the rope head to pass through the gap, so that it is clamped by the wire pulling mechanism.

[0024] Preferably, a receiving groove 18 is provided on the side of the knife seat 2, and a rolling member 19 is rotatably connected in the receiving groove 18, and the rolling end of the rolling member 19 can fit the inclined rod 14 or the vertical rod 13. Through this arrangement, sliding friction can be converted into rolling friction, and the whole process is smoother. For example, the rolling member 19 can be set as a roller.

[0025] Exemplarily, the wire pulling mechanism includes a horizontal moving platform 20 , on which a clamping member is disposed. The clamping member can clamp the shoelaces and pull the shoelaces to a preset length through the horizontal moving platform 20 .

[0026] Further, the clamping member includes: a second guide rail 21, the second guide rail 21 is fixedly connected to the horizontal moving platform 20; a relatively movable moving block 22, which is slidably connected to the second guide rail 21; and two symmetrically arranged clamping plates 23, which are respectively fixedly connected to the two movable blocks 22. Exemplarily, the movable block 22 is driven by a bidirectional screw and a motor.

[0027] Specifically, the first elastic member 6 includes a fixing plate 61 and a first spring 62 , the fixing plate 61 is fixedly connected to the end of the first guide rail 4 , one end of the first spring 62 is connected to the fixing plate 61 , and the other end of the first spring 62 is connected to the sliding seat 5 .

[0028] Specifically, the ear plate 7 is provided with a connected slot 24 and a slide groove 25; the snap-fitting component includes: a moving rod 26, a connecting block 27 and a rack 28; the moving rod 26 is slidably inserted into the slot 24, and the two sides of the connecting block 27 are respectively fixedly connected to the moving rod 26 and the rack 28, and the connecting block 27 is slidably connected to the slide groove 25, and the convex teeth of the rack 28 can be snapped into the tooth grooves of the gear 9.

[0029] Specifically, the second elastic member 10 is configured as a second spring, and one end of the second spring is fixedly connected to the connecting block 27 , and the other end of the second spring is fixedly connected to the end of the sliding groove 25 .

[0030] Preferably, the cutting knife 3 is located on a side of the knife holder 2 close to the wire pulling mechanism. The squeezing roller 8 is sleeved with an elastic rubber sleeve for clamping the shoelaces without damaging the shoelaces.

[0031] The specific implementation is as follows: Cutting mechanism: Power connection: A hydraulic cylinder 16 is fixedly connected to the carrier frame 15 , and the telescopic end of the hydraulic cylinder 16 extends to the lower side of the carrier frame 15 and is connected to the knife seat 2 , providing power for the lifting and lowering of the knife seat 2 .

[0032] Cutting structure: A cutting platform 17 is provided below the cutting knife 3, with a gap between the two to facilitate the shoelace rope ends to pass through and be clamped by the wire pulling mechanism.

[0033] Friction reduction design: A receiving groove 18 is provided on the side of the tool holder 2, and a rolling member 19 (such as a roller) is rotatably connected in the receiving groove 18 to convert sliding friction into rolling friction, so that the tool holder 2 moves more smoothly.

[0034] Wire pulling mechanism: Composition and function: It is composed of a horizontal moving platform 20 and a clamping member (a second guide rail 21, a moving block 22, and a clamping plate 23). The horizontal moving platform 20 is used to drive the clamping member to move and pull the shoelace rope.

[0035] Clamping member structure: The clamping member includes a second guide rail 21 fixed on the horizontal moving platform 20, a relatively movable moving block 22 slidably connected to the second guide rail 21, and symmetrically arranged clamping plates 23 respectively fixed on the two movable blocks 22.

[0036] Driving mode: The moving block 22 is driven by a bidirectional screw rod and a motor to realize the opening and closing of the clamping plate 23, thereby tightening or loosening the shoelaces.

[0037] Elastic parts related: First elastic member: The first elastic member 6 is composed of a fixing plate 61 and a first spring 62. The fixing plate 61 is fixed to the end of the first guide rail 4. Both ends of the first spring 62 are respectively connected to the fixing plate 61 and the sliding seat 5 for pushing the sliding seat 5 to reset.

[0038] Second elastic member: The second elastic member 10 is configured as a second spring, one end of which is connected to the connecting block 27 and the other end is connected to the end of the slide slot 25 , and is used to control the positions of the connecting block 27 and the rack 28 to achieve the engagement and disengagement of the gear 9 .

[0039] Other details: Squeezing roller protection: The squeezing roller 8 is covered with an elastic rubber sleeve, which can clamp the shoelace rope without damaging the shoelace rope.

[0040] Control structure: A slot 24 and a slide groove 25 are connected on the ear plate 7, and a moving rod 26, a connecting block 27 and a rack 28 form a clamping member. The moving rod 26 is slidably inserted in the slot 24, and the moving rod 26 and the rack 28 are connected on both sides of the connecting block 27, and the connecting block 27 slides in the slide groove 25. The convex teeth of the rack 28 can be clamped in the tooth groove of the gear 9 to realize the control of the rotation of the squeezing roller 8.

[0041] Working principle: When using, the details are as follows: Starting state: The clamping member of the wire pulling mechanism (including the second guide rail 21, the moving block 22, and the clamping plate 23) is in a ready state.

[0042] The hydraulic cylinder 16 is in a retracted state, and the tool holder 2 is in a higher position.

[0043] The squeezing roller 8 clamps the shoelace rope through the cooperation of the clamping piece (composed of a moving rod 26, a connecting block 27 and a rack 28) and the gear 9.

[0044] The sliding seat 5 is in the initial position, and the first elastic member 6 (including the fixing plate 61 and the first spring 62 ) is in a natural state.

[0045] Preparation stage: The horizontal moving platform 20 of the wire pulling mechanism drives the clamping member (the second guide rail 21, the moving block 22, and the clamping plate 23) to clamp the rope end of the shoelace rope and fix the starting position of the shoelace.

[0046] Pre-positioning operation: Action of hydraulic cylinder and knife holder: hydraulic cylinder 16 is started, and its telescopic end extends to push knife holder 2 down. When knife holder 2 descends, rolling element 19 in side receiving groove 18 rolls along inclined rod 14, and knife holder 2 pushes sliding seat 5 along first guide rail 4 to move to the side away from wire pulling mechanism through inclined rod 14.

[0047] Squeezing roller clamping: In this process, since the gear 9 is stuck by the rack 28 on the connecting block 27, the squeezing roller 8 coaxial with the gear 9 cannot rotate, thereby firmly clamping the shoelace rope.

[0048] The clamping part is disengaged: when the knife seat 2 drops to the connection between the oblique rod 14 and the vertical rod 13, the sliding seat 5 approaches the top rod 12, and the top rod 12 squeezes the moving rod 26, so that the connecting block 27 overcomes the elastic force of the second elastic member 10 (second spring) and moves, the rack 28 is disengaged from the tooth groove of the gear 9, and the squeezing roller 8 can rotate.

[0049] Wire positioning: The horizontal moving platform 20 of the wire pulling mechanism drives the clamping member (the second guide rail 21, the moving block 22, the clamping plate 23) to pull the shoelace rope to the side away from the cutting mechanism to reach a position determined by the preset cutting length.

[0050] Cutting stage: The knife seat descends: the hydraulic cylinder 16 continues to extend, and the knife seat 2 descends along the vertical rod 13. As the knife seat 2 descends along the vertical rod 13, the position of the sliding seat 5 remains unchanged.

[0051] Shoelace cutting: The cutting knife 3 on the knife holder 2 near the wire pulling mechanism cuts the shoelace rope, and the shoelace rope is cut at the gap between the cutting knife 3 and the cutting table 17.

[0052] Reset phase: Overall reset: After the cutting is completed, the hydraulic cylinder 16 contracts and the knife seat 2 resets upward. At the same time, the sliding seat 5 automatically resets under the action of the first elastic member 6 (first spring 62).

[0053] Squeezing roller reset and clamping: When the sliding seat 5 is reset, the moving rod 26 is no longer squeezed by the push rod 12. Under the action of the second elastic member 10 (the second spring), the connecting block 27 drives the rack 28 to clamp the tooth groove of the gear 9 again, and the squeezing roller 8 cannot rotate, thereby clamping the shoelace rope and pulling the rope end of the shoelace rope to one side of the wire pulling mechanism.

[0054] Prepare for the next time: Because there is a certain distance between the squeezing roller 8 and the cutting knife 3, part of the shoelace rope will be exposed during cutting, which is convenient for the wire pulling mechanism to clamp the rope end again to prepare for the next cutting.
