Description

Technical Field

[0001] This utility model relates to the field of shoe processing equipment technology, and in particular to a hot pressing molding device for insoles with automatic fixing function. Background Technology

[0002] Insoles are an important component of shoes, greatly improving their comfort. The manufacturing process involves cutting, pressing, and hot pressing. To enhance comfort, the insole's shape must conform to the shape of the sole. Since soles typically have curves to fit the foot, a hot pressing process is necessary. However, current technology presents the following problems after material feeding: First, insoles are usually placed directly in a fixed mold, resulting in poor fixation. During processing, the insole is prone to slippage, leading to a shape that doesn't meet requirements and impacting user comfort. Second, current technology often involves manual placement of the insole, which can result in misalignment and affect the accuracy of the final shape. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a hot pressing molding device for insoles with an automatic fixing function that can improve the accuracy of insole processing.

[0004] The technical solution of this utility model: A hot-press molding device for insoles with automatic fixing function, comprising a base, a molding device connected to the base, a fixing device connected to the base, and a controller. The molding device includes a shaping block fixedly connected to the base, a heating element connected to the shaping block, a sliding base slidably connected to the base, a fixing base fixedly connected to the sliding base, and a first hydraulic cylinder for driving the sliding base to move vertically. The fixing base is provided with a first limiting groove, and the shape and size of the shaping block are adapted to the first limiting groove, and the positions of the shaping block and the first limiting groove correspond. The fixing device includes a first positioning base slidably connected to the sliding base, a first pressing block movably connected to the first positioning base, and a controller. The base includes a second positioning base, a second clamping block movably connected to the second positioning base, a second hydraulic cylinder for driving the first positioning base to move horizontally, a third hydraulic cylinder for driving the second positioning base to move horizontally, a first rotary motor for driving the first clamping block to rotate, and a second rotary motor for driving the second clamping block to rotate. When the first and second clamping blocks rotate at a certain angle, the positions of the first and second clamping blocks correspond to the positions of the two ends of the first limiting groove, and the shaping block does not contact the first and second clamping blocks. The movement directions of the first and second positioning bases are opposite. The controller is electrically connected to the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder, the first rotary motor, the second rotary motor, and the heating element.

[0005] Using the above technical solution, firstly, the insole to be processed is placed on the first limiting groove. Then, the controller controls the second and third hydraulic cylinders to drive the first and second positioning bases to move horizontally towards each other a certain distance, so that the positions of the first and second pressing blocks correspond to the front and rear ends of the insole placed on the first limiting groove. Then, the controller controls the first and second rotary motors to control the first and second pressing blocks to press the two ends of the insole together. Then, the controller controls the first hydraulic cylinder to drive the sliding base to move vertically upward, thereby driving the fixed base to move vertically upward until the insole is pressed between the fixed base and the shaping block. Then, the first and second rotary motors drive the first and second pressing blocks to reset, so that the first and second pressing blocks release the two ends of the insole. Then, the controller controls the heating element to provide heat energy, thereby completing the shaping of the insole. Compared with traditional insole forming devices, this can prevent relative slippage of the insole during processing, thereby improving the yield.

[0006] A further feature of this invention is that a limiting baffle is provided on the first limiting groove, and the limiting baffle is adapted to the shape and size of the insole to be processed. When the insole to be processed contacts the limiting baffle, the shaping block corresponds to the position of the insole to be processed.

[0007] By adopting the above technical solution, since the first limiting groove is equipped with a limiting baffle, when the worker places the insole to be processed, it is only necessary to ensure that one side of the insole to be processed is in contact with the limiting baffle to ensure that the insole is in the correct processing position, thereby improving the processing accuracy and increasing the yield.

[0008] A further feature of this invention is that rubber pads are provided on the first pressing block and the second pressing block respectively, and the cross-sectional shape of the rubber pads is adapted to the cross-sectional shape and size of the first pressing block and the second pressing block respectively.

[0009] By adopting the above technical solution, since the first pressing block and the second pressing block are respectively provided with rubber pads, the rubber pads can increase the friction between the first pressing block or the second pressing block and the insole, further improving the stability of the insole position. In addition, the rubber pads have good flexibility, which can prevent the first pressing block or the second pressing block from wearing out during the pressing of the two ends of the insole, further improving the product yield.

[0010] Further features of this invention: the bottom of the fixed base is provided with several through holes, a suction head element connected to the through holes, a connecting pipe connected to the suction head element, and a negative pressure pump connected to the connecting pipe. The through holes are respectively connected to the first limiting groove. The through holes are evenly distributed at the bottom of the fixed base. The negative pressure pump is electrically connected to the controller.

[0011] By adopting the above technical solution, since the through holes are connected to the first limiting groove and are evenly distributed at the bottom of the fixed base, the negative pressure pump controlled by the controller provides negative pressure to the suction head element, thereby fixing the insole to the first limiting groove, and then performing subsequent hot pressing and shaping work, thereby further improving the positional stability during the processing of the insole and thus improving the product qualification rate.

Detailed Implementation

[0014] like Figure 1 As shown, a thermoforming device for insoles with automatic fixing function includes a base 1, a forming device 2 connected to the base 1, a fixing device 3 connected to the base 1, and a controller 4. The forming device 2 includes a shaping block 5 fixedly connected to the base 1, a heating element 6 connected to the shaping block 5, a sliding base 7 slidably connected to the base 1, a fixing base 8 fixedly connected to the sliding base 7, and a first hydraulic cylinder 9 for driving the sliding base 7 to move vertically. The fixing base 8 is provided with a first limiting groove 10. The shape and size of the shaping block 5 are adapted to the first limiting groove 10, and the positions of the shaping block 5 and the first limiting groove 10 correspond. The fixing device 3 includes a first positioning base 11 slidably connected to the sliding base 7, a first pressing block 12 movably connected to the first positioning base 11, a second positioning base 13 slidably connected to the sliding base 7, and a controller 4. The controller 4 is electrically connected to the second clamping block 14 of the second positioning base 13, the second hydraulic cylinder 15 for driving the first positioning base 11 to move horizontally, the third hydraulic cylinder 16 for driving the second positioning base 13 to move horizontally, the first rotary motor 17 for driving the first clamping block 12 to rotate, and the second rotary motor 18 for driving the second clamping block 14 to rotate. When the first clamping block 12 and the second clamping block 14 rotate at a certain angle, the positions of the first clamping block 12 and the second clamping block 14 correspond to the positions of the two ends of the first limiting groove 10, and the shaping block 5 does not contact the first clamping block 12 and the second clamping block 14. The movement directions of the first positioning base 11 and the second positioning base 13 are opposite. The controller 4 is electrically connected to the first hydraulic cylinder 9, the second hydraulic cylinder 15, the third hydraulic cylinder 16, the first rotary motor 17, the second rotary motor 18, and the heating element 6.

[0015] First, the insole to be processed is placed on the first limiting groove 10. Then, the controller 4 controls the second hydraulic cylinder 15 and the third hydraulic cylinder 16 to drive the first positioning base 11 and the second positioning base 13 to move towards each other in the horizontal direction a certain distance, so that the positions of the first pressing block 12 and the second pressing block 14 correspond to the front and rear ends of the insole placed on the first limiting groove 10. Then, the controller 4 controls the first rotary motor 17 and the second rotary motor 18 to control the first pressing block 12 and the second pressing block 14 to press the two ends of the insole together. The first hydraulic cylinder 9 drives the sliding base 7 to move vertically upward, thereby driving the fixed base 8 to move vertically upward until the insole is pressed between the fixed base 8 and the shaping block 5. Then, the first rotary motor 17 and the second rotary motor 18 respectively drive the first pressing block 12 and the second pressing block 14 to reset, so that the first pressing block 12 and the second pressing block 14 release the two ends of the insole. Then, the controller 4 controls the heating element 6 to provide heat energy, thereby completing the shaping of the insole. Compared with the traditional insole forming device 2, this can prevent relative slippage of the insole during the processing, thereby improving the yield.

[0016] The first limiting groove 10 is provided with a limiting baffle 19, which is adapted to the shape and size of the insole to be processed. When the insole to be processed contacts the limiting baffle 19, the shaping block 5 corresponds to the position of the insole to be processed.

[0017] Since the first limiting groove 10 is provided with a limiting baffle 19, when the worker places the insole to be processed, he only needs to ensure that one side of the insole to be processed is in contact with the limiting baffle 19 to ensure that the insole is in the correct processing position, thereby improving the processing accuracy and increasing the yield.

[0018] The first pressing block 12 and the second pressing block 14 are respectively provided with rubber pads 20, and the cross-sectional shape of the rubber pads 20 is adapted to the cross-sectional shape and size of the first pressing block 12 and the second pressing block 14 respectively.

[0019] Since the first pressing block 12 and the second pressing block 14 are respectively provided with rubber pads 20, the rubber pads 20 can increase the friction between the first pressing block 12 or the second pressing block 14 and the insole, further improving the stability of the insole position. In addition, the rubber pads 20 have good flexibility, which can prevent the first pressing block 12 or the second pressing block 14 from wearing out during the pressing of the two ends of the insole, further improving the product yield.

[0020] The bottom of the fixed base 8 is provided with several through holes 21, a suction head element 22 connected to the through holes 21, a connecting pipe 23 connected to the suction head element 22, and a negative pressure pump 24 connected to the connecting pipe 23. The through holes 21 are respectively connected to the first limiting groove 10. The through holes 21 are evenly distributed at the bottom of the fixed base 8. The negative pressure pump 24 is electrically connected to the controller 4.

[0021] Since the through holes 21 are connected to the first limiting groove 10 respectively, and the through holes 21 are evenly distributed at the bottom of the fixed base 8, the negative pressure pump 24 controlled by the controller 4 provides negative pressure to the suction head element 22, thereby fixing the insole to the first limiting groove 10, and then performing subsequent hot pressing and shaping work, thereby further improving the positional stability during the processing of the insole, and thus improving the product qualification rate.
