Description

Technical Field

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

[0002] Shoe edge-wrapping machines are key pieces of equipment in the footwear industry used to automatically process the edges of shoe upper components. They are mainly used for processing areas requiring fine wrapping and shaping, such as the toe and heel counter. Shoe edge-wrapping machines significantly improve the efficiency, consistency, and quality stability of edge-wrapping operations, avoiding the quality fluctuations and inefficiencies caused by manual operation. They are one of the core pieces of equipment for achieving high-quality leather shoes, athletic shoes, and casual shoes with beautiful silhouettes, comfortable wear, and durability, and are an indispensable component of modern intelligent footwear production lines.

[0003] When edge-wrapping shoes, workers usually operate the machine manually to move the shoes while a small-mouth high-head sewing machine sews the fabric to fix the bent leather to the edge of the shoe. One worker operates one machine, and the processing efficiency depends on the worker's skill level, resulting in low overall efficiency. Therefore, we propose a shoe edge-wrapping machine. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a shoe edge-wrapping machine that automates the edge-wrapping process, allows one person to manage multiple sets of equipment, improves edge-wrapping efficiency, and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shoe edge-wrapping machine, comprising a frame and an edge-wrapping mechanism; The frame has a small-mouth high-head carriage fixedly connected to the right end of its upper surface, and a two-axis linear guide rail fixedly connected to the upper surface of the recessed groove in the middle of the frame. The edge-wrapping mechanism includes a base, a servo rotary table, a rotating frame, a lower mold, and an upper mold. The base is fixedly connected to the upper end of the slide of the transverse linear guide rail of the two-axis linear guide. The servo rotary table is fixedly connected to the upper end of the base. The rotating frame is fixedly connected to the upper end of the rotating shaft of the servo rotary table. The lower mold is fixedly connected to the lower end of the rotating frame. The upper mold is set at the upper end of the rotating frame. Both the front and rear ends of the upper mold are hollow cavities. The upper mold and the lower mold are vertically aligned. The edge-wrapping process is automated, and one person can manage multiple sets of equipment, improving edge-wrapping efficiency.

[0006] Furthermore, it also includes a controller, which is set on the upper surface of the frame. The input end of the controller is electrically connected to an external power source, and the input ends of the small-mouth high-head carriage, servo rotary table and two-axis linear guide are all electrically connected to the output end of the controller to control electrical appliances.

[0007] Furthermore, the edge-wrapping mechanism also includes a mounting base and sliding columns. Three evenly distributed sliding columns are fixedly connected to the upper surface of the mounting base. The upper ends of the sliding columns are slidably connected to the interior of adjacent through holes at the upper end of the rotating frame, thereby driving the upper mold to rise and fall.

[0008] Furthermore, the edge-wrapping mechanism also includes a knob, which is threaded to the middle of the upper surface of the rotating frame. The left end of the knob's stud contacts the outer arc surface of the sliding column located in the middle to fix the sliding column.

[0009] Furthermore, the edge-wrapping mechanism also includes a pull plate, which is fixedly connected between the upper ends of the three sliding columns. The pull plate is located at the upper end of the rotating frame, which facilitates the pulling and pressing of the upper mold.

[0010] Furthermore, a fixed base is fixedly connected to the left end of the upper surface of the frame, and a positioning mold is fixedly connected to the upper surface of the fixed base. The right half of the shoe mold of the positioning mold fits against the edge of the lower mold to achieve shoe positioning.

[0011] Furthermore, an outer bending plate is fixedly connected to the left end of the upper surface of the support column of the small-mouth high-head carriage, and an inner bending plate is provided inside the outer bending plate. A guide column distributed in front and behind is fixedly connected to the right end of the upper surface of the support column of the small-mouth high-head carriage to guide the bending of the leather material.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This shoe edge-wrapping machine has the following advantages: During the edge-wrapping process, the worker places the semi-finished shoe onto the lower mold, positions it using the positioning mold, then presses down on the upper mold to fix it in place. The worker then manually guides the bent leather to fit the shoe edge, or the controller's path program controls the servo rotary table and two-axis linear guide rails to move and automatically fit the edge. The subsequent edge-wrapping process is driven by the servo rotary table and two-axis linear guide rails, which move and rotate the shoe. A small-mouth high-head sewing machine then performs the sewing. After edge-wrapping is complete, the worker cuts the leather and removes the shoe. The worker does not need to perform the complex edge-wrapping process; one person can oversee multiple shoe edge-wrapping machines, thus improving overall efficiency. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This embodiment provides a technical solution: a shoe edge-wrapping machine, including a frame 1 and an edge-wrapping mechanism 5; Frame 1: A small-mouth high-head carriage 3 is fixedly connected to the right end of its upper surface. A two-axis linear guide 4 is fixedly connected to the upper surface of the recessed groove in the middle of the frame 1. Then, the two-axis linear guide 4 drives the rotating frame 53 to move in the plane. The servo rotary table 52 drives the rotating frame 53 to rotate. The horizontal and vertical linear guides of the two-axis linear guide 4 are both servo linear guides. The rotary encoder integrated inside the servo linear guide can directly measure the position and speed to realize closed-loop control. At the same time, the controller 2 can program and store complex motion paths as fixed programs to realize intelligent edge wrapping of complex paths. The upper left end of the support column of the small-mouth high-head machine 3 is fixedly connected to an outer bending plate 7. An inner bending plate 8 is set inside the outer bending plate 7. The upper right end of the support column of the small-mouth high-head machine 3 is fixedly connected to guide columns 9 distributed front and rear. The leather is passed through the two guide columns 9, and the front end of the leather is inserted into the gap between the outer bending plate 7 and the inner bending plate 8, so that the leather is bent to facilitate subsequent edge wrapping. A gasket is welded between the inner bending plate 8 and the outer bending plate 7 to make the inner bending plate 8 and the outer bending plate 7 a whole. Edge-wrapping mechanism 5: It includes a base 51, a servo rotary table 52, a rotating frame 53, a lower mold 54, and an upper mold 55. The base 51 is fixedly connected to the upper end of the slide of the transverse linear guide of the two-axis linear guide 4. The upper end of the base 51 is fixedly connected to the servo rotary table 52. The upper end of the rotating shaft of the servo rotary table 52 is fixedly connected to the rotating frame 53. The lower end of the rotating frame 53 is fixedly connected to the lower mold 54. The upper end of the rotating frame 53 is provided with the upper mold 55. The front and rear ends of the upper mold 55 are hollow cavities. The upper mold 55 and the lower mold 54 are vertically aligned. The worker places the semi-finished shoe to be edge-wrapped on the lower mold 54. The shoe size corresponding to the lower mold 54 is 2-4 sizes smaller than the semi-finished shoe, leaving the edge of the semi-finished shoe empty. Then the upper mold 55 is pressed down. The upper of the semi-finished shoe is manually inserted into the hollow cavities at the front and rear ends of the upper mold 55 by the worker to avoid affecting the subsequent edge-wrapping. The edge-wrapping mechanism 5 also includes a mounting base 56 and sliding pillars 58. Three evenly distributed sliding pillars 58 are fixedly connected to the upper surface of the mounting base 56. The upper ends of the sliding pillars 58 are slidably connected to the interior of adjacent through holes at the upper end of the rotating frame 53. The edge-wrapping mechanism 5 also includes a knob 57, which is threadedly connected to the middle of the upper surface of the rotating frame 53. The left end of the stud of the knob 57 contacts the outer arc surface of the sliding pillar 58 located in the middle. The edge-wrapping mechanism 5 also includes a pull plate 59, which is fixedly connected between the upper ends of the three sliding pillars 58. The pull plate 59 is located at the upper end of the rotating frame 53. When the upper mold 55 is pressed down, the worker holds the pull plate 59 and presses down the whole assembly of the mounting base 56 and sliding pillars 58, which drives the upper mold 55 to press down. After visually confirming that the semi-finished shoe has been pressed down, the worker rotates the knob 57. The stud of the knob 57 presses against the middle sliding pillar 58, thereby locking the position of the upper mold 55. A fixed base 10 is fixedly connected to the left end of the upper surface of the frame 1. A positioning mold 6 is fixedly connected to the upper surface of the fixed base 10. The right half of the shoe mold of the positioning mold 6 fits against the edge of the lower mold 54. The left edge of the semi-finished shoe completely overlaps with the right half of the shoe mold of the positioning mold 6, thereby achieving the positioning of the semi-finished shoe.

[0017] The system also includes a controller 2, which is located on the upper surface of the frame 1. The input of the controller 2 is electrically connected to an external power source. The inputs of the small-mouth high-head carriage 3, the servo rotary table 52, and the two-axis linear guide rail 4 are all electrically connected to the output of the controller 2.

[0018] The working principle of the shoe edge wrapping machine provided by this utility model is as follows: push the frame 1 to a suitable position in the workshop. Two directional casters with foot brakes are fixedly connected to the left end of the lower surface of the frame 1 to facilitate straight movement. Two universal wheels with foot brakes are fixedly connected to the right end of the lower surface of the frame 1 to facilitate turning. The leather is passed through two guide posts 9, and the front end of the leather is inserted into the gap between the outer bending plate 7 and the inner bending plate 8, so that the leather can be bent to facilitate subsequent edge wrapping. A gasket is welded between the inner bending plate 8 and the outer bending plate 7 to make the inner bending plate 8 and the outer bending plate 7 a whole. Workers place the semi-finished shoes to be edged on the lower mold 54. The shoe size corresponding to the lower mold 54 is 2-4 sizes smaller than the semi-finished shoes, leaving the edges of the semi-finished shoes empty. The left edge of the semi-finished shoes is completely aligned with the right half of the shoe mold edge of the positioning mold 6 to achieve the positioning of the semi-finished shoes. Then, the upper mold 55 is pressed down, and the upper of the semi-finished shoes is manually inserted by workers into the hollow cavities at the front and rear ends of the upper mold 55 to avoid affecting the subsequent edge-wrapping. When the upper mold 55 is pressed down, the worker holds the pull plate 59 and presses down the whole assembly of the mounting base 56 and the sliding column 58, which drives the upper mold 55 to press down. After visually confirming that the semi-finished shoe is pressed down, the worker turns the knob 57. The stud of the knob 57 presses against the sliding column 58 in the middle, thereby locking the position of the upper mold 55. Subsequently, the two-axis linear guide 4 drives the rotating frame 53 to move in the plane, and the servo rotary table 52 drives the rotating frame 53 to rotate. The horizontal and vertical linear guides of the two-axis linear guide 4 are both servo linear guides. The rotary encoder integrated inside the servo linear guide can directly measure the position and speed to realize closed-loop control. At the same time, the controller 2 can program and store complex motion paths as fixed programs to realize intelligent edge wrapping of complex paths. The semi-finished shoes are brought to the sewing position of the small-mouth high-head sewing machine 3. The path can be set so that the semi-finished shoes fit the bent leather from the left rear direction, so that the beginning part of the leather automatically wraps the edge of the semi-finished shoes. Alternatively, after the semi-finished shoes arrive at the sewing position, the worker manually guides the leather to wrap the edge of the semi-finished shoes. Then, the worker controls the edge wrapping program to start through the controller 2, and the small-mouth high-head sewing machine 3 starts sewing. The two-axis linear guide 4 and the servo rotary table 52 work together to make the semi-finished shoes move and rotate along the set path to achieve edge wrapping. Different models and shoe sizes require the corresponding lower mold 54, upper mold 55 and positioning mold 6 to be replaced. At the same time, the path fixing program inside the controller 2 is adjusted. After the shoe edge is finished, the worker cuts the leather, presses the reset button on controller 2, and all mechanisms automatically reset. The worker then releases knob 57 and removes the shoe. A single machine needs to complete multiple processes, including material loading and fixing, automatic edge wrapping, reset, and material removal. The total time may be longer than that of a single skilled worker. However, the worker does not need to perform the most complex edge wrapping process, so there are no requirements for the worker's skill level. At the same time, one worker can supervise multiple shoe edge wrapping machines, thereby improving overall efficiency.

[0019] It is worth noting that the controller 2 disclosed in the above embodiments can be a TPC7012EI touch PLC all-in-one machine, the small mouth high head carriage 3 can be a 335PF small mouth high head carriage, the linear guide rail of the two-axis linear guide rail 4 can be an NSS series servo linear module, and the servo rotary table 52 can be an HRG series servo rotary platform. The controller 2 controls the small mouth high head carriage 3, the two-axis linear guide rail 4 and the servo rotary table 52 using methods commonly used in the prior art.

[0020] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
