Description

Shoemaking elastic band straightening device Technical Field

[0001] This utility model belongs to the field of sewing machines and relates to a smoothing device, particularly a smoothing device for elastic bands used in shoemaking. Background Technology

[0002] In the process of splicing elastic bands into rings, bundles or rolls of elastic bands are used as raw materials. After being cut into sections, they are sewn into rings. During this production process, irregularly wrinkled or twisted elastic bands need to be ironed and smoothed to ensure that the elastic bands entering the subsequent processes are flat, and to avoid uneven surface and inconsistent ring diameters.

[0003] Currently, the ironing and smoothing process mentioned above is generally completed using corresponding equipment. For example, a shaping and material handling mechanism disclosed in the Chinese Patent Database (application number: 202210250501.X) includes a bracket, on which a pressure plate driven by a first cylinder is mounted. A heating plate is mounted on the bracket relative to the pressure plate. A material pulling component for pulling the elastic band is mounted on one end of the bracket corresponding to the heating plate. A material clamping component is mounted on the other end of the bracket corresponding to the heating plate. The material clamping component is used to press the elastic band tightly to prevent it from moving further.

[0004] In the aforementioned material handling mechanism, a conveying channel is formed between the heating plate and the pressure plate for the elastic band to pass through. Because the heating plate and the pressure plate are relatively hard, there will be a certain gap between the elastic band and the heating plate when the elastic band is squeezed, which affects the ironing and smoothing quality of the elastic band. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a high-quality shoe-making elastic band smoothing device.

[0006] The purpose of this utility model can be achieved through the following technical solution: a shoe elastic band smoothing device, including a frame and a heating plate and a fabric pressing plate, both vertically arranged on the frame, the heating plate and the fabric pressing plate facing each other, the frame is also provided with a driving component for driving the fabric pressing plate closer to or away from the heating plate, characterized in that a high-temperature resistant soft pad is abutted and fixed on the side of the fabric pressing plate close to the heating plate, the high-temperature resistant soft pad and the heating plate facing each other and forming a conveying channel for the elastic band to pass through.

[0007] During use, the drive unit moves the fabric pressure plate and presses the elastic band onto the heating plate through a high-temperature resistant pad, so as to eliminate creases on the elastic band through high-temperature ironing.

[0008] The fabric pressing plate uses a flexible and elastic high-temperature resistant pad to press the elastic band onto the heating plate, which allows the elastic band to make better and fuller contact with the heating plate, greatly enhancing the crease elimination effect and improving the shaping quality.

[0009] In the aforementioned shoe-making elastic band smoothing device, there are at least two fabric pressure plates arranged vertically at intervals. The number of driving components, high-temperature resistant pads, and fabric pressure plates are equal, and their positions correspond one-to-one. Each high-temperature resistant pad is positioned directly opposite the heating plate. By providing multiple high-temperature resistant pads arranged vertically at intervals, and each pad being driven by a separate driving component, the pressing force of different high-temperature resistant pads can be adjusted during actual use. This ensures that the elastic band is shaped more effectively while allowing it to pass more smoothly through the conveyor channel.

[0010] In the aforementioned shoe-making elastic band smoothing device, the driving component is a cylinder. The fabric pressure plate is positioned between the corresponding cylinder and the corresponding high-temperature resistant pad, and the cylinder piston rod is fixedly connected to the corresponding fabric pressure plate. This design keeps the cylinder away from the heating plate, thereby extending the cylinder's lifespan.

[0011] In the aforementioned shoe-making elastic band smoothing device, a heat insulation pad is provided between the corresponding cylinder and the fabric pressure plate, and the corresponding fabric pressure plate and the corresponding cylinder piston rod are fixedly connected to both sides of the heat insulation pad. The heat insulation pad is designed to form a heat insulation barrier between the cylinder and the fabric pressure plate, further reducing heat transfer to the cylinder and extending the cylinder's lifespan.

[0012] In the aforementioned shoe-making elastic band smoothing device, the high-temperature resistant pad is a high-temperature resistant silicone foam pad. The high-temperature resistant silicone foam pad possesses the advantages of strong high-temperature resistance and high elasticity, making the goal of improving shaping quality more consistently achieved.

[0013] In the aforementioned shoe-making elastic band smoothing device, the frame includes a frame body and detachable positioning plates fixed to the frame body. The positioning plates are vertically arranged, and the number of positioning plates and cylinders are the same, with their positions corresponding one-to-one. The heating plate and cylinders are respectively fixed to the frame body and the corresponding positioning plates. This design modularizes the cylinders, positioning plates, fabric pressing plates, and high-temperature resistant pads, facilitating maintenance.

[0014] In the aforementioned shoemaking elastic band smoothing device, the positioning plate has an L-shaped cross-section, with both ends of the positioning plate pressing against the frame. Both ends of the positioning plate are detachably fixed to the frame by screws to stably position the positioning plate.

[0015] Compared with existing technologies, this shoe-making elastic band smoothing device has the following advantages:

[0016] 1. The fabric pressing plate uses a flexible and elastic high-temperature resistant soft pad to press the elastic band onto the heating plate, which allows the elastic band to make better and fuller contact with the heating plate, greatly enhancing the crease elimination effect and improving the shaping quality.

[0017] 2. Multiple high-temperature resistant pads are arranged vertically at intervals, and each high-temperature resistant pad is driven by a separate drive unit. In actual use, the holding force of different high-temperature resistant pads can be adjusted, which can not only meet the requirements of strengthening the shaping quality of the elastic band, but also make the elastic band pass through the conveyor channel more smoothly.

Detailed Implementation

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] As shown in Figure 1, this shoemaking elastic band smoothing device includes a frame 1, a material guiding mechanism 2, a material pulling mechanism 3, and a heating plate 4 and a fabric pressing plate 5, all of which are vertically mounted on the frame 1.

[0024] in,

[0025] As shown in Figures 1 to 3, the heating plate 4 and the fabric pressing plate 5 are positioned opposite each other. The frame 1 is also equipped with a drive unit for moving the fabric pressing plate 5 closer to or away from the heating plate 4. A high-temperature resistant pad 7 is abutted and fixed to the side of the fabric pressing plate 5 closest to the heating plate 4. The high-temperature resistant pad 7 and the heating plate 4 are positioned opposite each other, forming a conveyor channel 8 through which the elastic band passes. In use, the drive unit moves the fabric pressing plate 5, pressing the elastic band onto the heating plate 4 via the high-temperature resistant pad 7, thereby eliminating creases on the elastic band through high-temperature ironing. In actual products, the high-temperature pad is bonded and fixed to the corresponding fabric pressing plate 5.

[0026] The fabric pressure plate 5 presses the elastic band onto the heating plate 4 through the high-temperature resistant soft pad 7, which is both flexible and elastic. This allows the elastic band to make better and fuller contact with the heating plate 4, greatly enhancing the crease elimination effect and improving the shaping quality.

[0027] To further explain, there are at least two fabric pressure plates 5, arranged vertically at intervals. The number of driving components, high-temperature resistant pads 7, and fabric pressure plates 5 are the same, and their positions correspond one-to-one. Each high-temperature resistant pad 7 is positioned directly opposite the heating plate 4 to form the aforementioned conveying channel 8. By setting multiple high-temperature resistant pads 7 arranged vertically at intervals, and each high-temperature resistant pad 7 being driven by a separate driving component, the pressing force of different high-temperature resistant pads 7 can be adjusted during actual use. This ensures that the elastic band is shaped more effectively while allowing it to pass through the conveying channel 8 more smoothly.

[0028] The guiding mechanism 2 is positioned above the uppermost conveying channel 8 to smoothly guide the elastic band into the conveying channel 8; the pulling mechanism 3 is positioned below the lowermost conveying channel 8 to pull the elastic band downwards. Both the guiding mechanism 2 and the pulling mechanism 3 are existing technologies; for details, please refer to a shaped material handling mechanism disclosed in the Chinese Patent Database (application number: 202210250501.X).

[0029] In this embodiment,

[0030] As shown in Figures 2 and 3, the driving component is a cylinder 6, and the fabric pressure plate 5 is located between the corresponding cylinder 6 and the corresponding high-temperature resistant pad 7, with the piston rod of the cylinder 6 fixedly connected to the corresponding fabric pressure plate 5. This design keeps the cylinder 6 away from the heating plate 4, thus extending its lifespan. Of course, using an electric push rod as the driving component, with its main shaft fixedly connected to the corresponding fabric pressure plate 5, is also possible. Further, a heat insulation pad 9 is provided between the corresponding cylinder 6 and the fabric pressure plate 5, with the corresponding fabric pressure plate 5 and the piston rod of the corresponding cylinder 6 fixedly connected to both sides of the heat insulation pad 9. The heat insulation pad 9 forms a heat insulation barrier between the cylinder 6 and the fabric pressure plate 5, further reducing heat transfer to the cylinder 6 and extending its lifespan.

[0031] High-temperature resistant pad 7 is a high-temperature resistant silicone foam pad. High-temperature resistant silicone foam pads possess the advantages of strong high-temperature resistance and high elasticity, making it easier to achieve the goal of improving shaping quality.

[0032] The cylinder 6 is installed as follows: The frame 1 includes a frame body 1a and a positioning plate 1b detachably fixed to the frame body 1a. The positioning plate 1b is vertically arranged, and the number of positioning plates 1b and cylinders 6 are the same and their positions correspond one-to-one. The heating plate 4 and cylinder 6 are respectively fixed to the frame body 1a and the corresponding positioning plate 1b. With the above design, the cylinder 6, positioning plate 1b, fabric pressing plate 5, and high-temperature resistant soft pad 7 can be modularized for easy maintenance. Preferably, the cross-section of the positioning plate 1b is L-shaped, with both ends of the positioning plate 1b pressing against the frame body 1a, and both ends of the positioning plate 1b are detachably fixed to the frame body 1a by screws to stably position the positioning plate 1b.
