Description

Technical Field

[0001] The utility model belongs to the technical field of coil processing, and particularly relates to a cutting tool head assembly for coil processing. Background Technique

[0002] Coils are different from other papers. During the processing, special cutting equipment is required for cutting. It can not only divide the coils into different parts, but also cut the surrounding contours of the coils to the corresponding sizes. For the convenience of use, some coils will also be subjected to incomplete cutting and pressing on the back of the coils, so that it is easy to divide these coils into different parts during the later splitting and use process; the original coil cutting equipment generally uses a single tool head to cut the coils horizontally or vertically. At this time, the cutting tool head is distributed horizontally and perpendicular to the coils. The cutting tool head is driven by a moving bracket to move horizontally in the horizontal direction.

[0003] A patent with the application number "CN202122960689.0" and named "A cutting device for materials used in advertising light boxes" mentions that "A cutting device for materials used in advertising light boxes, through the clamping component, it is convenient to press and fix the poster on the support platform. The setting of the slideway facilitates the movement of the horizontal guide rail, and then drives the cutting head to cut the poster horizontally and vertically from different starting points, which is convenient to adjust the cutting size. The installation component with an elastic member can make the cutting head cut the poster when the pressing plate is pressed. After releasing the pressing plate, the elastic member resets, pushes up the pressing plate, drives the movable rod and the cutting head to rise, and prevents the cutting head from scratching the poster when moving the horizontal guide rail". Its cutting head and the movable rod are directly connected, and the position of the cutting head cannot be adjusted as needed. In actual use, there are cutting tool heads that are movably connected to the support device, but they are all single cutting tool heads, which are very inconvenient to adjust. Especially for the tool head that needs to move left and right, it is very difficult to ensure that both the left and right directions are horizontal and perpendicular to the advertising coil at the same time.

[0004] Therefore, there is an urgent need for a cutting tool head assembly for coil processing, which can solve the technical problems that the position adjustment of the cutting tool head in the existing equipment is inconvenient and it is difficult for the cutting tool head to achieve the cutting effect in both directions at the same time through the design of two cutting tool heads. Summary of the Invention

[0005] In view of this, the utility model proposes a cutting tool head assembly for coil processing, which is applied to coil processing to solve the technical problems of complex structure, inconvenient adjustment of the position of the cutting tool head and poor adjustment accuracy of the cutting tool head during the use of a cutting tool head assembly for coil processing.

[0006] In order to achieve the above technical purpose, the specific technical solutions adopted by the utility model are as follows:

[0007] A cutting tool head assembly for coil processing, comprising a blade base, a blade support and a circular tool head. The blade support is arranged on one side of the blade base. There are two circular tool heads, which are arranged at the bottom of the blade support. The two circular tool heads are fixedly connected to the blade support through the long axis at their central positions. There are two vertically extending connecting long grooves on the blade support. Each connecting long groove is located inside the corresponding limiting long groove arranged on the side wall of the blade base. The upper end of each connecting long groove is rotationally connected to the upper end of the corresponding limiting long groove in the front-rear direction. The inside of each connecting long groove is fixedly connected to the side wall of the blade base through the corresponding fixing screw and a return spring. The fixing screw is located inside the long strip through hole arranged on the side wall of the connecting long groove and penetrates into the side wall of the blade base, so as to fix the connecting long groove on the limiting long groove. The return spring is sleeved on the limiting screw that horizontally passes through the blade support and penetrates into the side wall of the blade support. The return spring is arranged between the top of the limiting screw and the side wall of the blade support.

[0008] Further, a sliding clamping groove is arranged at the rear side of the blade base, and is slidably connected with a supporting long rod arranged outside the tool head assembly through the sliding clamping groove, so as to limit the moving direction of the blade base.

[0009] Further, connecting rods that horizontally pass through the limiting long grooves are arranged at the tops of the two connecting long grooves. The two connecting rods are fixedly connected to the tops of the corresponding connecting long grooves. The tops of the two connecting rods are rotationally connected to the tops of the corresponding limiting long grooves, which is convenient for the lower part of the connecting long groove to swing around the connecting rod in the front-rear direction. The two long strip through holes are respectively arranged in the middle of the corresponding connecting long grooves. The two return springs are respectively located below the corresponding long strip through holes. The left and right positions of the two limiting screws and the long strip through holes are the same as the left and right positions of the long axis of the corresponding circular tool head.

[0010] Further, connecting discs are arranged at the rear ends of the two long axes. Each circular tool head is fixed on the connecting disc through four connecting screws evenly distributed around the long axis.

[0011] Further, the connecting disc is sleeved on the rear end of the corresponding long axis. The circular tool head rotates around the long axis during the process of following the blade base to move horizontally.

[0012] Further, a limiting through hole through which the limiting screw passes is arranged inside the connecting long groove. The return spring presses against the periphery of the limiting through hole.

[0013] Adopting the above technical solution, the present utility model can also bring the following beneficial effects:

[0014] 1. The utility model drives the left - right movement of the blade support by the left - right movement of the blade base, thereby driving the left - right movement of the circular cutter head, facilitating the cutting of the coil by the circular cutter head. The connection between the circular cutter head and the blade support is strengthened through the connection disk and the long shaft, and it can also facilitate the rotation of the circular cutter head during the cutting of the coil, thereby reducing the friction received by the circular cutter head, effectively extending the service life of the circular cutter head, and also facilitating the replacement of the circular cutter head by removing the connection screws.

[0015] 2. The utility model fixes the blade support on one side of the blade base through the connection of the connecting long groove and the limiting long groove. Since the connecting long groove is located inside the limiting long groove, it prevents the connecting long groove from moving horizontally inside the limiting long groove. The top of the connecting long groove is connected to the top of the limiting long groove through the connecting rod, thereby preventing the connecting long groove from moving up and down inside the limiting long groove. The middle and lower parts of the limiting long groove are connected through the fixing screw, the return spring and the limiting screw. Through the rebound of the return spring and the length of the fixing screw extending into the blade base, it is convenient to adjust the front - rear position of the bottom of the connecting long groove, thereby conveniently adjusting the vertical angle of the circular blade in the front - rear direction, so as to ensure that the circular blade is at the best angle for cutting the coil.

[0016] 3. The utility model reduces the difficulty in adjusting the angle of the circular cutter head through the setting of two circular cutter heads, and can also ensure that the circular cutter head can still cut the coil from two directions after the angle is conveniently adjusted by preferentially cutting in the corresponding directions by the two circular cutter heads, improving the cutting efficiency. The adjustment of the front - rear positions of the lower parts of the connecting long groove and the limiting long groove is facilitated through the long strip through - hole and the limiting through - hole, further reducing the difficulty of cutting the angle of the circular cutter head.
