Description

Technical Field

[0001] The utility model belongs to the field of sewing machines and relates to a smoothing device, in particular to a rubber band smoothing device for shoemaking. Background Art

[0002] In the process of splicing elastic bands into loops, bundles or rolls of elastic bands are used as raw materials. They are cut into sections and sewn into loops. During this production process, irregularly wrinkled or twisted elastic bands need to be ironed and smoothed to ensure the flatness of the elastic bands entering the subsequent process, avoiding uneven surfaces and uneven diameters of the elastic bands.

[0003] At present, the above-mentioned ironing and smoothing process is generally completed by corresponding equipment. For example, a shaping and sorting mechanism disclosed in the China Patent Library (application number: 202210250501.X) includes a bracket, on which a pressing plate driven by a first cylinder is provided, and a heating plate is provided on the bracket relative to the pressing plate. A pulling assembly for pulling the rubber band is provided at one end of the bracket corresponding to the heating plate; a clamping assembly is installed at the other end of the bracket corresponding to the heating plate, and the clamping assembly is used to press the rubber band to prevent it from continuing to move.

[0004] In the above-mentioned material sorting mechanism, a conveying channel for the rubber band to pass through is formed between the heating plate and the pressing plate. Since the heating plate and the pressing plate themselves are relatively hard, there will be a certain gap between the rubber band and the heating plate when the rubber band is squeezed, which affects the ironing and smoothing quality of the rubber band. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the existing technology and to propose a shoemaking rubber band smoothing device with high shaping quality.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a rubber band smoothing device for shoemaking, comprising 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 being arranged opposite each other, and the frame is also provided with a driving member for driving the fabric pressing plate close to or away from the heating plate, characterized in that a high-temperature resistant pad is abutted and fixed on the side of the fabric pressing plate close to the heating plate, the high-temperature resistant pad and the heating plate being arranged opposite each other and a conveying channel for the rubber band to pass through is formed between the two.

[0007] When in use, the driving part drives the fabric pressing plate to move, and presses the elastic band onto the heating plate through the high-temperature resistant soft pad, so as to eliminate the creases on the elastic band by high-temperature ironing.

[0008] The fabric pressing plate squeezes the rubber band onto the heating plate through a high-temperature resistant cushion that is both flexible and elastic, which allows the rubber band to better and fully contact the heating plate, greatly enhancing the crease elimination effect and improving the shaping quality.

[0009] In the aforementioned shoemaking rubber band smoothing device, there are at least two fabric pressing plates spaced vertically apart. The driving member, high-temperature resistant pads, and fabric pressing plates are identical in number and positioned in a one-to-one correspondence, with each high-temperature resistant pad positioned directly opposite the heating plate. Multiple high-temperature resistant pads are provided, each driven by a separate driving member. This allows for adjustable pressure on the different high-temperature resistant pads during actual use, ensuring smoother passage of the rubber band through the conveying channel while enhancing the shaping quality of the rubber band.

[0010] In the aforementioned shoemaking rubber band smoothing device, the driving element is a pneumatic cylinder. The fabric pressing plate is located between the corresponding pneumatic cylinder and the corresponding high-temperature-resistant cushion, and the cylinder piston rod is fixedly connected to the corresponding fabric pressing plate. This design keeps the pneumatic cylinder away from the heating plate, thereby extending the cylinder's life.

[0011] In the aforementioned shoemaking elastic band smoothing device, a thermal insulation pad is installed between the corresponding cylinders and the fabric pressing plate. The pads are fixedly connected to the corresponding fabric pressing plate and the corresponding cylinder piston rod on either side. The thermal insulation pads form a thermal barrier between the cylinders and the fabric pressing plate, further reducing heat transfer to the cylinders and extending their lifespan.

[0012] In the above-mentioned shoemaking rubber band smoothing device, the high-temperature resistant soft pad is a high-temperature resistant silicone foam pad. The high-temperature resistant silicone foam pad has the advantages of strong high-temperature resistance and high elasticity, which makes the purpose of improving the shaping quality more stable.

[0013] In the aforementioned shoemaking elastic band smoothing device, the frame comprises a frame and a removable positioning plate fixed to the frame. The positioning plate is vertically arranged, with the same number of positioning plates as cylinders, and their positions corresponding to each other. The heating plate and cylinder are respectively fixed to the frame and the corresponding positioning plate. This design allows the cylinder, positioning plate, fabric pressing plate, and high-temperature-resistant cushion to be modularized for easier maintenance.

[0014] In the above-mentioned rubber band smoothing device for shoemaking, the cross section of the positioning plate is L-shaped, both ends of the positioning plate are pressed against the frame, and both ends of the positioning plate are detachably connected to the frame by screws to stably position the positioning plate.

[0015] Compared with the existing technology, this shoemaking rubber band smoothing device has the following advantages:

[0016] 1. The fabric pressing plate squeezes the rubber band onto the heating plate through a high-temperature resistant cushion that is both flexible and elastic, which allows the rubber band to better and fully contact the heating plate, greatly enhancing the crease elimination effect and improving the shaping quality.

[0017] 2. Set up multiple high-temperature resistant soft pads with vertical intervals, and each high-temperature resistant soft pad is driven by a separate driving member. In this way, the holding force of different high-temperature resistant soft pads can be adjusted in actual use, while meeting the premise of strengthening the shaping quality of the rubber band and making the rubber band pass through the conveying channel more smoothly.

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] like Figure 1 As shown, the shoemaking rubber 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 both vertically arranged on the frame 1.

[0024] in,

[0025] like Figures 1 to 3 As shown, the heating plate 4 and the fabric pressing plate 5 are positioned opposite each other. The frame 1 is also equipped with a drive element for moving the fabric pressing plate 5 toward or away from the heating plate 4. A high-temperature-resistant cushion 7 is affixed to and positioned on the side of the fabric pressing plate 5 proximal to the heating plate 4. The cushion 7 and the heating plate 4 are positioned opposite each other, forming a conveying channel 8 for the elastic band to pass through. During use, the drive element actuates the fabric pressing plate 5, which, through the high-temperature-resistant cushion 7, presses the elastic band against the heating plate 4, thereby eliminating creases in the elastic band through high-temperature ironing. In actual production, the high-temperature cushion is bonded to the corresponding fabric pressing plate 5.

[0026] The fabric pressing plate 5 squeezes the rubber band onto the heating plate 4 through the high temperature resistant cushion 7 which is both flexible and elastic, so that the rubber band can better and fully contact the heating plate 4, greatly enhancing the crease elimination effect and improving the shaping quality.

[0027] To further illustrate, there are at least two fabric pressing plates 5, spaced vertically apart. The number of drive members, high-temperature resistant cushions 7, and fabric pressing plates 5 is identical and their positions correspond one to one. Each high-temperature resistant cushion 7 is positioned directly opposite the heating plate 4 to form the aforementioned conveying channel 8. Multiple high-temperature resistant cushions 7 are provided, spaced vertically apart, and each is driven by a separate drive member. This allows the pressure of the different high-temperature resistant cushions 7 to be adjusted during actual use, ensuring smoother passage of the rubber band through the conveying channel 8 while still enhancing the shaping quality of the rubber band.

[0028] The material guide mechanism 2 is located above the topmost conveying channel 8 and is used to smoothly guide the rubber band into the conveying channel 8. The material pulling mechanism 3 is located below the bottommost conveying channel 8 and pulls the rubber band downward. Both the material guide mechanism 2 and the material pulling mechanism 3 are prior art. For details, please refer to a standardized material handling mechanism disclosed in the China Patent Library (Application No.: 202210250501.X).

The above design is adopted to keep the cylinder 6 away from the heating plate 4 to extend the life of the cylinder 6. Naturally, it is also possible to adopt the method of "the type of driving member is an electric push rod, and the main shaft of the electric push rod is fixedly connected to the corresponding fabric pressing plate 5". Further explanation: a heat insulation pad 9 is provided between the corresponding cylinder 6 and the fabric pressing plate 5, and the two sides of the heat insulation pad 9 are respectively fixedly connected to the corresponding fabric pressing plate 5 and the corresponding cylinder 6 piston rod. The heat insulation pad 9 is provided to form a heat insulation barrier between the cylinder 6 and the fabric pressing plate 5, further reducing the heat transfer to the cylinder 6 and extending the life of the cylinder 6.

[0031] The high temperature resistant soft pad 7 is a high temperature resistant silicone foam pad. The high temperature resistant silicone foam pad has the advantages of strong high temperature resistance and high elasticity, which makes the purpose of improving the shaping quality more stable.

[0032] The cylinder 6 is installed as follows: the frame 1 includes a frame body 1a and a positioning plate 1b that is detachably fixed to the frame body 1a. The positioning plate 1b is vertically arranged. The positioning plates 1b and cylinders 6 have the same number and their positions correspond one to one. The heating plate 4 and the cylinder 6 are respectively fixed to the frame body 1a and the corresponding positioning plate 1b. The above design can make the cylinder 6, the positioning plate 1b, the fabric pressing plate 5 and the high-temperature resistant cushion 7 modular, which is convenient for maintenance. Preferably, the cross-section of the positioning plate 1b is L-shaped, and both ends of the positioning plate 1b are pressed 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.
