Description

Technical Field

[0001] The utility model relates to the technical field of safety shoe production, in particular to a heel shaping device for safety shoe production. Background Art

[0002] Safety shoes are a general term for safety shoes and protective shoes. They generally refer to shoes worn in different workplaces to protect the feet and legs from foreseeable injuries. Different safety shoes have different application scopes and different requirements for the functions of safety shoes. They can protect the soles of the feet from being stabbed by sharp objects.

[0003] For example, a heel shaping device for safety shoe production with the authorization announcement number "CN218682432U" is provided. Through the setting of the heel clamping unit, under the elastic force of the spring, the first clamping plate clamps and limits the two sides of the heel, and under the action of the elastic telescopic rod, the second clamping plate clamps and limits the upper end of the heel. Through the setting of the upper clamping unit, an appropriate number of clamping rods are selected according to the size of the upper and inserted into the jacks at the corresponding positions. Under the action of the groove and the rubber clamping strip, the upper is clamped. However, the heel shaping device for the production of safety shoes drives the first clamping plate to limit the heel through the elastic force of the spring. After limiting the wider heel, the physical strength of the spring is damaged. The next time the narrower heel is limited, it cannot be limited. The operator needs to switch to other machines that are compatible with it for processing, which increases the working limitations. At the same time, the heel shaping device for the production of safety shoes requires the operator to manually adjust when it is necessary to clamp the shoe upper. Since the operator needs to manually adjust each time, it consumes more physical strength of the operator, thereby increasing the manual labor. Utility Model Content

[0029] Working principle:

[0030] When using shaping equipment to shape the heels during the production of safety shoes:

[0031] Preparation process:

[0032] Heel fixing process:

[0033] The operator opens the front opening and closing plate 11, places the heel between the two clamping plates 605, and starts the power supply of the fourth hydraulic cylinder 602. The telescopic end of the fourth hydraulic cylinder 602 retracts to drive the first slider 603 to move, thereby driving the two connecting rods 604 to move. The movement of the two connecting rods 604 drives the two clamping plates 605 to slide along the surface of the fixed plate 606. At the same time, the clamping plates 605 slide relatively along the through holes processed on the first shell 601. When the surfaces of the two clamping plates 605 are tightly fitted with the surface of the heel, the power supply of the fourth hydraulic cylinder 602 is turned off, so that after clamping a wider heel, the narrower heel can still be clamped, thereby reducing the working limitations.

[0034] Upper fixing process:

[0035] The operator opens the rear opening and closing plate 11, places the shoe upper between the two limit plates 13, and starts the power supply of the first motor 902 on the left. The output shaft of the first motor 902 rotates clockwise to drive the threaded rod 903 to rotate, thereby driving the second slider 904 to slide along the surface of the fixed column 905. The second slider 904 moves to drive the cross bar 907 to slide to the right along the through hole processed on the second shell 901, and compresses the spring 907 at the same time. Similarly, the power supply of the first motor 902 on the right is started, and the output shaft of the first motor 902 rotates counterclockwise to drive the right cross bar 907 to slide to the left. The two cross bars 907 move relative to each other, driving the two limit plates 13 to move relative to each other. When the surfaces of the two limit plates 13 are tightly fitted with the surface of the shoe upper, the power supplies of the two first motors 902 are turned off, so that the operator does not need to consume more physical strength, thereby saving manual labor.

[0036] Heel spraying process:

[0037] The operator starts the power supply of the first hydraulic cylinder 7, and the telescopic end of the first hydraulic cylinder 7 extends to drive the protruding part of the first movable plate 8 to slide along the slide groove processed on the inner wall of the box body 1, thereby driving the heel to move. When the heel moves to the rear of the spray plate 5, the power supply of the first hydraulic cylinder 7 is turned off, and the operator starts the external power supply of the paint pump to pump the glue into the hose 10 and enter the spray plate 5, so that the glue head installed on the spray pipe 5 outputs. When the surface of the heel is attached with glue, the power supply of the glue pump is turned off, and the operator starts the power supply of the second hydraulic cylinder 4. The telescopic end of the second hydraulic cylinder 4 extends to drive the spray plate 5 to slide along the slide groove processed on the box body 1. When the surface of the sliding roller 12 is tightly fitted with the surface of the heel, the power supply of the second hydraulic cylinder 4 is turned off, and then the power supply of the first hydraulic cylinder 7 is started. The telescopic end of the first hydraulic cylinder 7 moves back and forth, driving the first movable plate 8 to move back and forth, thereby driving the heel to move back and forth, so that the glue sprayed on the surface of the heel is leveled.

[0038] Heel and upper shaping process:

[0039] When the glue level sprayed on the heel surface is level, the operator starts the power supply of the second hydraulic cylinder 4, the telescopic end of the second hydraulic cylinder 4 retracts, driving the spray plate 5 to reset, and then the telescopic end of the first hydraulic cylinder 7 extends to drive the heel to continue to move to the left. When the heel surface is facing the upper surface, the power supply of the first hydraulic cylinder 7 is turned off, and the power supply of the third hydraulic cylinder 2 is started. The telescopic end of the third hydraulic cylinder 2 extends to drive the second movable plate 3 to slide backward along the surface of the protruding part of the box body 1. When the upper and the heel surface are closely fitted, the power supply of the third hydraulic cylinder 2 is turned off, and a section After that, the glue bonds the heel and the upper together, thereby completing the heel shaping work. The operator rotates the output shaft of the left first motor 902 counterclockwise and the output shaft of the right first motor 902 clockwise to drive the two limit plates 13 away from the upper. When the two limit plates 13 are reset, the power of the two first motors 902 is turned off, and then the power of the fourth hydraulic cylinder 602 is started. The telescopic end of the second hydraulic cylinder 602 extends to drive the two clamping plates 605 gradually away from the upper, and then the operator takes out the shaped heel.
