Description

Technical Field

[0001] The invention relates to the technical field of shoe material processing equipment, and in particular to a shoe sole cold pressing and shaping device. Background Art

[0002] Cold pressing is a processing method that flattens the surface of a workpiece by taking advantage of the characteristics of plastic deformation, or uses a cold pressing die to plasticize the workpiece.

[0003] In the process of sole production, there is a manufacturing method that uses a cold pressing step. The specific steps are as follows: 1. Cold pressing the foamed sheet to form a rough upper; 2. Cutting the rough upper to make a shoe panel; 3. Applying glue to the bottom surface of the shoe panel and bonding the connecting cloth; 4. Applying glue to the other side of the connecting cloth and bonding the sole plate.

[0004] In the process of cold pressing the sole, the staff needs to put the heated foaming material from the heating box on the cooled mold, and then squeeze the blank through the upper pressing plate after adjusting the blank, so as to shape the blank; however, the existing sole cold pressing shaping device has the following problems:

[0005] 1. When cold pressing the blank, the blank will be placed directly on the cooled mold. At this time, the staff also needs to adjust the position of the blank, and it takes a certain amount of time for the upper pressing plate to descend, which causes the temperature of the blank and the mold to be cooled first. As a result, after the blank is cold pressed and shaped, the part of the blank that is cooled first has a poor shaping effect, and there will be rebound after shaping, thus affecting the final cold pressing effect of the sole;

[0006] 2. Existing cold presses all use air cooling or water cooling to cool the mold, which has a slow cooling speed and affects the production efficiency of the soles;

[0007] 3. The existing cold press machine requires the staff to remove the cold-pressed blank from the mold and then put the blank taken out from the heating box on the mold, which results in slow processing efficiency. Summary of the invention

[0008] In order to solve the above problems, the present invention provides a sole cold pressing and shaping device, which can avoid the contact between the blank and the mold before the blank is pressed down for shaping, resulting in the bottom of the blank being cooled first and affecting the shaping; at the same time, the blank can be automatically sent to the top of the mold, thereby improving the processing efficiency.

DETAILED DESCRIPTION

[0049] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0050] like Figure 1-7 As shown, this embodiment discloses a shoe sole cold pressing and shaping device, including a frame 1, a workbench 2 is arranged on the frame 1, an aluminum condensing plate 3 is arranged on the workbench 2, an evaporator 82 of a refrigerator 8 is arranged below the workbench 2, and is located below the condensing plate 3. When the refrigerator 8 is working, the surface of the condensing plate 3 will be condensed and frozen; a positioning groove 11 is arranged on the condensing plate 3, and a mold 4 is placed in the positioning groove 11. Through heat exchange, the condensing plate 3 will cool down the mold 4. Figure 1 As shown, a preparation rack 6 is provided on the workbench 2. When the staff needs to cold-press the blank, the blank is placed on the material plate 62 and arranged, and then the button 71 is pressed. The button 71 controls the cylinder to descend, so that the upper pressing plate 5 descends to press the blank toward the mold 4. During this process, the material plate 62 will be moved downward, so that the blank above it will be pressed downward together until the blank is fitted with the mold 4.

[0051] In the above structure, through the setting of the preparation rack 6, the blank will not directly contact the cooled mold before the upper pressing plate 5 descends, thereby avoiding the contact between the blank and the mold, which causes the blank to be partially cooled and shaped first, affecting the cold pressing molding quality; at the same time, the upper pressing plate will first contact the material plate 62 during the descending process, so that the blank can be clamped between the material plate 62 and the upper pressing plate 5, and the blank is clamped and positioned, avoiding the movement of the blank during the movement process; thereby, the quality of the cold pressing of the blank can be guaranteed.

[0052] At the same time, when the mold 4 and the upper pressing plate 5 are cold-pressing and shaping the blank, in the existing cold pressing process, since there is a groove on the mold surface that matches the shape of the sole, the surrounding side of the blank will shrink and deform in the direction of the groove during the process of the upper pressing plate pressing the blank, thereby causing the blank to move, affecting the quality of the sole pressing and forming.

[0053] like Figure 1-2 As shown, insulation boxes 9 are provided on both sides of the frame 1, and a conveying mechanism is provided between the insulation box 9 and the mold 4. The conveying mechanism can enable the preparation rack 6 to circulate between the insulation box 9 and the mold 4, thereby facilitating the transportation of the blanks, so that the staff does not need to repeatedly take the blanks, reducing the labor of the staff.

[0054] The heat preservation box 9 includes a box body 91, and heating tubes 94 are arranged on both sides of the box body 91. The opening and closing of the heating tubes can be controlled by the control panel 72, and the temperature in the box body 91 can be controlled and adjusted by the temperature sensor, so as to achieve the heat preservation of the blank;

[0055] The workbench 2 is also provided with a chain 101, and the preparation rack 6 is clamped on the chain 101 through a connecting block 102, so that when the first servo motor is started, the preparation rack 6 can be controlled to carry the blank to move in the direction of the mold 4, and the through groove 63 on the material plate 62 is matched with the mold 4, thereby realizing automatic transportation of the blank.

[0056] During use, the staff first places the heated blanks on the top of the insulated box 9. A material box is placed at the feed inlet 92 of the insulated box 9. The blanks in the material box will enter the box body 91 from the feed inlet 92 under the action of gravity. Figure 2-3 As shown, chains A are arranged on both sides of the box 91, and support rods 97 are arranged at equal distances on the chain A. The support rods 97 symmetrically arranged on both sides can support the blank. When the preparation rack 6 reaches the bottom of the discharge port 93 of the box 91 through the chain 101, the receiver on the material plate 62 will trigger the infrared sensor located below the box 91, thereby controlling the second servo motor to start, driving the chain A in the box 91 to move, driving the bottom blank to break away from the support plate and fall onto the material plate through the discharge port 93, and then the staff presses the button 71, and the button 71 first drives the first servo motor to start through the PLC control module, thereby driving the preparation rack located below the incubator 9 to move to the top of the mold, and then the cylinder starts to cold-press the blank onto the mold 4, and then after a certain period of cold pressing, the cylinder rises, and then the material plate 62 rises under the action of elastic force, and drives the shaped blank to break away from the mold, which facilitates demoulding, and then the staff takes the shaped blank to cut it, and presses the button to continue to control the conveying and cold pressing of the blank.

[0057] like Figure 7 As shown, the connection structure of the refrigerator 8 is shown in the figure, and its connection structure is the same as the compression refrigeration device disclosed in patent publication number (CN206771788U), so it will not be elaborated in detail.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
