Description

TECHNICAL FIELD

[0001] The present application relates to a shoe pad cutting device, in particular to a customized shoe pad cutting device with rapid shaping. BACKGROUND

[0002] With the development of society, intelligent machines and convenient devices are rapidly penetrating people's lives. However, in the field of shoe pad cutting, most shoe pad manufacturers still use traditional manufacturing methods such as injection molding and stamping. The degree of intelligent production is low, and it is difficult to meet the individual customization needs of people with different foot shapes in the shoe pad production process. For example, some people have physiological diseases such as toe valgus and thumb valgus. Over time, the shape of the shoes of people with such physiological diseases will change with the shape of the feet, resulting in poor fit of traditional shoe pads. It is difficult to buy customized shoe pads that fit their foot shape. Usually, they need to perform secondary processing on the shoe pads before putting them into the shoes to make them fit the shape of the shoes and the soles. The number of such people is large, and the demand is huge. The existing method of customizing shoe pads usually uses traditional measurement methods to obtain the foot shape by stepping on a mold, then measures the size of the sole, and then transfers it to the shoe pad cutting process for production. However, this method has complex steps, high cost, and low efficiency, which is difficult for ordinary people to afford. Only a few people, such as athletes, need to customize running shoes and choose this method to customize shoe pads. Therefore, this method cannot be widely promoted and applied.

[0018] Further, a receiving groove which is communicated with the outside of the lower box body is arranged on the bottom plate of the lower box body, and a receiving plate is arranged in the receiving groove.

[0019] The working principle of the application is as follows:

[0020] The application provides a cutting device for a customized insole which is quickly shaped, and the upper box body and the lower box body are designed in a split mode, a foot sole measuring position is arranged on the upper box body, the foot sole measuring position is a foot sole type groove for placing the foot sole, and a plurality of distance meters around the foot sole measuring position are used to measure the distance between the initial position of the distance meter and the foot, so as to provide telescopic data for the telescopic knife holder in the insole cutting device.

[0021] The insole clamping device in the lower box body is used to clamp the insole raw material sheet, the upper pressing plate and the lower lining plate are pressed and fixed to the insole raw material sheet, so that the insole raw material sheet is conveniently cut; the lower lining plate is provided with a cutting through hole which is vertically arranged, the blade for cutting is moved upward to pass through the cutting through hole of the lower lining plate, and the insole raw material sheet is extruded and cut.

[0022] The variable gap between the upper pressing plate and the lower lining plate can adapt to insole raw material sheets with different thicknesses, and the insole raw material sheet is extruded and fixed by reducing the gap; the insole raw material sheet is inserted between the upper pressing plate and the lower lining plate from the strip-shaped through hole arranged in the side wall of the lower box body.

[0023] The blade of the insole cutting device is a strip-shaped soft blade which can be wound up by the blade reel.

[0024] The number of telescopic knife holders is the same as the distance meters, and the positions are vertically corresponding to the distance meters. The displacement distance measured by each distance meter is converted into the displacement distance of the corresponding telescopic knife holder. The telescopic knife holders respectively push the blade to bend to form the shape of the insole corresponding to the foot shape.

[0025] The telescopic knife holder drives the blade to move horizontally and vertically through the horizontal and vertical telescopic devices. The blade clamping part clamps and limits the blade. The blade edge is higher than the upper end of the blade clamping part, which is convenient for cutting the insole raw material sheet.

[0026] The controller transmits signals with each electrical equipment and controls the operation of each electrical equipment.

[0027] Further, the pressure sensor at the foot sole measurement position is connected with the controller for signal transmission. When the foot steps on the foot sole measurement position, the pressure sensor is triggered, indicating that the foot has been located at the foot sole measurement position, and the measurement can be started.

[0028] Further, the distance meter is connected with the horizontal telescopic rod. The horizontal telescopic rod drives the distance meter to approach or move away from the foot sole measurement position in the horizontal direction. During the extension to the foot, the front contact of the horizontal telescopic rod sends a signal to the controller after contacting the foot, and the controller controls the horizontal telescopic rod to stop running. All horizontal telescopic rods jointly abut against the foot to prevent the displacement of the foot during the measurement to cause measurement error. The distance meter measures the moving distance and sends the data signal to the controller during the process. Since the cut insole should be slightly larger than the actual foot sole size, a horizontal distance of 1-3 mm is reserved between the front end of the distance meter and the front end of the contact. According to the actual needs of the user, the position of the distance meter can be adjusted to further adjust the distance, so as to reserve a size larger than the actual foot sole for the insole.

[0029] For the blade reel, in one form, the blade reel is sleeved on the upper shaft rod of the reel seat. The blade reel inside is pulled by the reset coil spring to wind the excess part of the blade on the blade reel. When the length of the required blade increases, the traction force of the telescopic knife holder overcomes the torque of the reset coil spring to make the blade reel rotate outward to release a part of the blade. When the length of the required blade decreases, the torque of the reset coil spring makes the blade reel rotate inward to recover the excess length of the blade.

[0030] For the blade reel, in another form, the blade reel is sleeved on the motor output shaft of the reel seat. The motor is controlled and driven by the controller to drive the blade reel to rotate. When the length of the required blade increases, the motor makes the blade reel rotate outward to release a part of the blade. When the length of the required blade decreases, the motor makes the blade reel rotate inward to recover the excess length of the blade.

[0031] Further, the telescopic knife holder controls the horizontal telescopic arm to drive the blade clamping part to move forward and backward in the horizontal direction, and controls the vertical telescopic arm to drive the blade clamping part to move up and down in the vertical direction; the two guide shafts of the blade clamping part are cylindrical and can rotate freely, the blade passes between the two guide shafts, and the gap between the two guide shafts is not less than the thickness of the blade, so that the blade can pass between the two guide shafts.

[0032] Further, the end of the blade is fixed on the rotating shaft of the limiting end rod and can rotate freely; the limiting end rod is arranged at the heel, and the blade reel is arranged on the same side of the limiting end rod and is located outside the limiting end rod; after the blade winds around the limiting end rod for one turn, the limiting end rod is wrapped by the blade reel; when the telescopic knife holder pushes the blade inward, the required length of the blade becomes smaller, the blade reel winds up the excess length of the blade, and the inward force of the blade pushes the limiting end rod to slide inward along the sliding groove, so that the width of the blade at the heel is reduced.

[0033] Further, the cut-out insole falls on the receiving plate in the receiving groove, and the insole can be taken out by pulling out the receiving plate from the insertion hole outside the lower box body.

[0034] The control process of the present application is as follows:

[0035] Before measurement, the controller controls all devices to reset to the initial position; the initial positions of the plurality of telescopic knife holders and the initial positions of the corresponding distance meters are located at the same coordinate in the horizontal direction; the upper pressing plate is lifted to maximize the distance between the upper pressing plate and the lower lining plate;

[0036] The insole raw material piece to be cut is inserted between the upper pressing plate and the lower lining plate through the strip-shaped through hole in the side wall of the lower box body; the controller controls the vertical telescopic rod on the upper pressing plate to extend downward, and moves the upper pressing plate to the lower lining plate to press the insole raw material piece;

[0037] The user places the foot on the foot palm measurement position; after the pressure sensor of the foot palm measurement position detects a pressure signal, the signal is transmitted to the controller, indicating that the foot palm has been detected on the foot palm measurement position, and the measurement can be started;

[0038] The controller sends a control signal to the plurality of distance meters and the horizontal telescopic rod; the horizontal telescopic rod drives the distance meter to move towards the foot palm until the contact head contacts the foot palm and stops moving; the distance meter calculates the stroke of the distance meter by subtracting the distance between the initial position and the foot palm from the distance between the final position and the foot palm, and sends the result to the controller;

[0039] The controller controls the corresponding telescopic knife holder to extend forward according to the data measured by each distance meter, and the forward extension distance of the telescopic knife holder is equal to the displacement distance of the corresponding distance meter; after the plurality of telescopic knife holders extend forward to the position, the blade is enclosed to form the shape of the foot palm, i.e. the shape of the insole to be cut.

[0040] The controller controls the vertical telescopic device of the telescopic tool holder to rise upward, drives the blade to move upward, and the cutting edge penetrates through the cutting through hole on the lower lining plate and extrudes the cutting shoe pad raw material sheet under the lifting force of the vertical telescopic device;

[0041] The cut shoe pad falls on the receiving plate in the receiving groove, the receiving plate is pulled out from the insertion hole of the lower box body side wall, the cut shoe pad is taken out, and the cutting work of one shoe pad is completed.
