Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in the attached drawings 1-9, the utility model provides a vertical braid foot cutting device, which comprises a fixed cutter 1, a movable cutter 2 and a cutter fixing seat 3 for fixing the movable cutter 2, wherein a foot cutting area 4 for accommodating a pin 20 is formed between the fixed cutter 1 and the movable cutter 2; still including being used for driving moving cutter 2 and being close to or the drive assembly who keeps away from to fixed cutter 1, drive assembly includes step motor 5 and sets up camshaft 6 on step motor 5 output shaft, and 3 bottoms of cutter fixing base are established on camshaft 6 through being capsule shape through-hole 14 cover of erectting, and the cover is equipped with ball bearing 13 on camshaft 6 and is connected with the through-hole rotation through ball bearing 13.

It should be noted that the movable cutter 2 is fixed on the top of the cutter fixing seat 3, the fixed cutter 1 is fixed on the top of the stop block fixing seat, and the cutter fixing seat 3 and the stop block fixing seat are arranged on the base side by side. The bottom end of the cutter fixing seat 3 penetrates through the base, the base is provided with a through groove capable of accommodating the cutter fixing seat 3 to move horizontally, and the stop block fixing seat is fixed at one end of the base. The cross section of the movable cutter 2 is inverted trapezoid, the cutting edge of the movable cutter is inclined, the cross section of the fixed cutter 1 is rectangular, when the movable cutter 2 approaches the fixed cutter 1, the upper end face of the movable cutter 2 is attached to the lower end face of the fixed cutter 1, and the inclined cutting edge cuts off the pins 20 of the braiding element 19 sequentially under the driving of the stepping motor 5, so that the cutting surfaces of the pins 20 of the braiding element 19 are more orderly, and the pins 20 left on the same braiding element 19 are equal in length.

In addition, the camshaft 6 is sleeved with a ball bearing 13, the bottom end of the cutter fixing seat 3 is sleeved on the ball bearing 13 through a vertical capsule-shaped through hole 14, and therefore when the stepping motor 5 drives, the camshaft 6 rotates around the output shaft of the motor. Because the through-hole of 3 bottoms of cutter fixing base is capsule shape through-hole 14, consequently camshaft 6 when circling around the rotation along the output shaft of motor, promotes cutter 2 fixing base along base horizontal migration, also is close to or keeps away from to the dog fixing base, drives the separation and reunion between movable cutter 2 and the fixed cutter 1, will place in and cut off the pin 20 of the braid component 19 of foot district 4. Simultaneously, be equipped with the slider in cutter fixing base 3 bottom, the cooperation sets up the slide rail at the base up end, and when realizing motor drive, cutter fixing base 3 moved more smoothly, moves more steadily tangent between cutter 2 and the fixed cutter 1, cuts off pin 20 after, and the cut surface is more level and smooth, reduces the crooked and the condition of cut surface unevenness of pin 20.

Of course, the base is provided with the first sensor 15 and the second sensor 16 which are used for sensing the cutter fixing seat 3, the corresponding positions of the cutter fixing seat 3 are provided with the first light-shielding sheet 17 and the second light-shielding sheet 18, and the positions of the first light-shielding sheet 17 and the second light-shielding sheet 18 can be adjusted, so that the requirements of adjusting the moving distance of each part are met. The first sensor 15 and the second sensor 16 can accurately control the movement of the cutter fixing seat 3 by sensing the information of the first light shielding sheet 17 and the second light shielding sheet 18.

Further, a cutter pressing plate 7 used for fixing the fixed cutter 1 is arranged on the upper end face of the fixed cutter 1, a prepressing plate 8 used for matching the fixed cutter 1 and pressing the pins 20 is arranged above the movable cutter 2, the prepressing plate 8 is connected with the upper end of the cutter fixing seat 3 through a first sliding pin 9, and a spring is sleeved on the first sliding pin 9. The upper end face of the cutter pressing plate 7 is provided with a stop block 10 used for stopping a braiding element 19, the stop block 10 is set to be adjustable in position according to the size of the element, the upper end face of the prepressing plate 8 is provided with a clamping block 11 used for matching the stop block 10 and clamping the braiding element 19, the clamping block 11 is connected with the upper end of the cutter fixing seat 3 through a second sliding pin 12, and a spring is sleeved on the second sliding pin 12.

It should be noted that, because the pre-pressing plate 8 and the clamping block 11 are connected to the top end of the cutter fixing seat 3 through the first sliding pin 9 and the second sliding pin 12, the first sliding pin 9 and the second sliding pin 12 are respectively sleeved with a spring, when the cutter fixing seat 3 approaches the stopper 10 fixing seat, the clamping block 11 cooperates with the stopper 10 to clamp the tape element 19, and when the pre-pressing plate 8 cooperates with the fixed cutter 1 to press the pin 20, the tape element 19 and the pin 20 are not deformed.

The principle of the device is as follows: the stepping motor 5 works to drive the cam shaft 6 to rotate, and then the ball bearing 13 on the cam shaft 6 pushes the cutter 2 fixing seat to be close to the stop block fixing seat, so as to drive the movable cutter 2 to be close to the fixed cutter 1. When the first sensor 15 senses the first shade 17, the stepping motor 5 stops operating. At the moment, the clamping block 11 is matched with the stop block 10 to clamp the braiding element 19, the prepressing plate 8 is matched with the fixed cutter 1 to press the pin 20, the pin 20 is prevented from bending and deforming during pin cutting, and the movable cutter 2 further cuts the pin 20. When the stepping motor 5 rotates in the opposite direction, the components are reset, and the second sensor 16 senses the information of the second light shielding sheet 18, the stepping motor 5 stops working and is reset to the position.

This vertical braid foot cutting device through rational design for it is more stable when the device cuts the foot, and the braid component can not lead to the crushing because of excessively pressing from both sides tightly. After the foot is cut, the cutting surface of the braiding element is more neat, and the pins cannot be bent and deformed due to the foot cutting. Meanwhile, the compact design of the device also enables the volume of the whole device to be smaller, and the device meets the requirement of the market on small and exquisite equipment.
