Description

Technical Field

[0001] This utility model belongs to the field of knitting needle manufacturing technology, and in particular relates to an electric cutting machine. Background Technology

[0002] A needle cutting machine is an important piece of equipment in the needle cutting process. It is mainly used to cut off excess needle length, improving needle consistency and reducing the need for frequent machine switching in certain processes. Publication number CN211707872U relates to a tooling for manufacturing needle tongue holes, belonging to the field of needle tongue punching tooling technology. It includes a die holder, a bottom die support mounted on the die holder, a bottom die mounting hole on the upper surface of the bottom die support, a punching bottom die fixedly mounted in the bottom die mounting hole, and a punching bottom die with a center at the top for inserting a punch.

The sliding rod is slidably mounted inside a sleeve, which is fixedly mounted on a die base. A guide mechanism is provided between the sliding rod and the sleeve. The top of the sliding rod is connected to a power lifting unit. A pin tongue limiting block is also installed on the die base. The vertical distance between the limiting surface of the pin tongue limiting block and the center of the punching hole at the top of the punching die is the distance from the center of the pin tongue hole to the top of the pin tongue. This device is used to solve the technical problems of poor processing quality of the pin tongue and easy breakage of the punch in the prior art.

[0003] However, existing technologies have some problems: existing needle cutting machines directly cut the needle blanks with a punch, which can easily cause the needle blanks to bend when the punch presses them, affecting the quality of the knitting needles. In addition, the needle cutting machine generates a lot of waste during use. Existing needle cutting machines cannot automatically collect the waste, and manual collection of waste and finished products is required. Therefore, we propose a punch waste recycling track to solve the above problems. Thus, we propose an electric cutting machine. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model has a material distribution component in the groove. When the device cuts the needle blank, the excess needle feet are cut off and enter the slag collection box through the discharge port on the lower template. After the upper template is cut, it is driven to move upward by the first hydraulic rod. At this time, the third hydraulic rod pushes the push plate so that the cut needles are moved to the flattening component through the discharge port. This avoids material accumulation and affects the operation of the device, while also reducing the workload of the workers.

[0017] 2. This utility model is equipped with a demolding component. Issues such as unsuitable mold material and surface roughness, poor processing material condition, insufficient lubrication, and excessive pressure and heat from the punching machine may cause the needle blank to stick to the pressure plate after cutting and fail to fall off automatically. This utility model provides a pressure head on the pressure plate. When cutting the needle blank, the pressure head on the pressure plate compresses the second spring, causing the pressure rod to retract into the groove of the pressure plate. After cutting, the pressure head extends out of the groove due to the rebound force of the second spring, thus popping away any needle blanks that may be stuck to the surface of the pressure plate, thereby preventing the needle blanks from sticking to the pressure plate after cutting and failing to fall off automatically for collection.

[0018] 3. This utility model is equipped with a flattening component. The push plate moves the cut knitting needles through the discharge port to the lower roller in the flattening component. The rotation of the lower roller drives the knitting needles to move. When the knitting needles move between the upper roller and the lower roller, the upper roller and the lower roller will flatten the knitting needles to prevent them from bending. At the same time, the distance between the upper roller and the lower roller can be adjusted by the second hydraulic rod, so that the device can flatten knitting needles of different thicknesses.

[0027] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0028] like Figures 1 to 6 As shown in the figure, the electric foot cutter provided in this embodiment of the utility model includes a base 1, which is rectangular and made of stainless steel. The main function of the base 1 is to support the entire device.

[0029] The base 1 has a groove, and the lower template 2 is fixedly connected to the inner wall of the groove. The lower template 2 is rectangular and made of high-strength stainless steel. The lower mold 3 is detachably connected to the upper end of the lower template 2. The lower mold 3 is detachably connected to the lower template 2 with screws. The lower mold 3 can be replaced according to the required cutting needle shape.

[0030] An upper template 4 is movably connected to the inner wall of the groove in the base 1, and a limit rod 10 is fixedly connected to the upper end of the lower template 2. The limit rod 10 is a cylindrical stainless steel column, and its main function is to support the upper template 4 and prevent the upper template 4 from shifting during the cutting process.

[0031] An avoidance hole is provided on the upper template 4, and the limiting rod 10 passes through the avoidance hole. The upper template 4 slides on the limiting rod 10. A first hydraulic rod 11 is fixedly connected inside the base 1. The upper end of the upper template 4 is fixedly connected to the movable end of the first hydraulic rod 11. The first hydraulic rod 11 is used to drive the upper template 4 to slide on the limiting rod 10.

[0032] The upper template 4 is detachably connected to the upper mold 5. The upper mold 5 is detachably connected to the upper template 4 by screws. The upper mold 5 includes a cutting plate 501. A punch 502 is fixedly connected to the lower end of the cutting plate 501. A pressure plate 503 is movably connected to the lower end of the cutting plate 501. An avoidance hole is provided on the pressure plate 503. The punch 502 can pass through the avoidance hole. The demolding component 6 is set inside the pressure plate 503.

[0033] A groove is provided on the cutting plate 501, and a connecting rod 504 is slidably connected in the groove. A pressure plate 503 is fixedly connected to the connecting rod 504. A first spring 505 is fixedly connected to the upper end of the pressure plate 503. The first spring 505 is fixedly connected to the lower end of the cutting plate 501, and the connecting rod 504 is disposed in the first spring 505.

[0034] When cutting the needle blank, the pressure plate 503 first contacts the needle blank. The pressure plate 503 and the lower mold 3 work together on the needle blank to fix it and prevent the needle blank from shifting during the cutting process. Then, the cutting plate 501 compresses the first spring 505 and continues to move downward, so that the punch 502 passes through the pressure plate 503 to cut the needle blank.

[0035] The demolding assembly 6 includes a slide rod 601, and a groove is provided at the lower end of the pressure plate 503. The slide rod 601 is slidably connected in the groove. One end of the slide rod 601 is fixedly connected to a pressure head 602. The pressure head 602 is fixedly connected to a second spring 603. The second spring 603 is fixedly connected to the inner wall of the groove.

[0036] Before the pressure plate 503 contacts the needle blank, the pressure head 602 first contacts the needle blank. Then, the pressure head 602 is compressed by the second spring 603, causing the pressure head 602 to retract into the groove of the pressure plate 503. When the needle blank is cut, as the first hydraulic rod 11 moves the pressure plate 503 upward, the pressure head 602 is pushed out of the groove by the rebound force of the second spring 603, thereby popping the needle blank away and preventing the needle blank from sticking to the pressure plate 503 after cutting and failing to fall off automatically for collection.

[0037] The material distribution component 7 includes a slag collection box 701, which is movably connected to the base 1. A discharge port is provided in the middle of the lower template 2, and the slag collection box 701 is located below the discharge port.

[0038] The material distribution assembly 7 also includes a third hydraulic rod 702, which is fixedly connected to the inner wall of the groove of the base 1. The third hydraulic rod 702 is fixedly connected to a push plate 703, and a discharge port 704 is fixedly connected to one side of the lower template 2.

[0039] When the device cuts the knitting needle blank, excess needle feet are removed and collected in the slag collection box 701 through the discharge port on the lower template 2. After cutting, the upper template 4 is moved upward by the first hydraulic rod 11. At this time, the third hydraulic rod 702 pushes the push plate 703 to move the cut knitting needle into the flattening component 8 through the discharge port 704. This avoids material accumulation affecting the operation of the device and reduces the workload of the workers.

[0040] A cavity is provided inside the base 1, and a leveling component 8 is provided inside the cavity. The leveling component 8 includes multiple sets of lower rollers 801, and a transmission belt 805 is fitted on the multiple sets of lower rollers 801. The transmission belt 805 is used to make the multiple sets of lower rollers 801 rotate synchronously. The lower rollers 801 are rotatably connected to the cavity of the base 1. A drive component 12 is provided inside the base 1, and the drive component 12 is used to drive the lower rollers 801 to rotate. An adjustment platform 802 is movably connected to the base 1.

[0041] A second hydraulic rod 803 is fixedly connected inside the base 1. An adjusting platform 802 is fixedly connected to the movable end of the second hydraulic rod 803. Multiple sets of upper rollers 804 are rotatably connected to the adjusting platform 802. The adjusting platform 802 can be moved by the second hydraulic rod 803, thereby changing the distance between the upper rollers 804 and the lower rollers 801, so that this utility model can roll knitting needles of different thicknesses.

[0042] The drive assembly 12 includes a motor 121, which is fixedly connected to the base 1. A first gear 122 is fixedly connected to the output end of the motor 121. A second gear 124 is fixedly connected to one end of the lower roller 801. A chain 123 is provided between the first gear 122 and the second gear 124, and the chain 123 meshes with the first gear 122 and the second gear 124.

[0043] The motor 121 is started, which drives the first gear 122 to rotate. The first gear 122 then drives the chain 123 to rotate, and the chain 123 then drives the second gear 124 to rotate. The second gear 124 drives one set of lower rollers 801 to rotate, and then drives multiple sets of lower rollers 801 to rotate synchronously through the transmission belt 805, so that the knitting needles are rolled flat by the flattening component 8.

[0044] A control console 9 is fixedly connected to the other side of the base 1. A display screen and control buttons are fixedly connected to the upper end of the control console 9. A control unit is also installed inside the control console 9. The main function of the control console 9 is to control the operation of the entire device.

[0045] The working principle of this utility model is as follows:

[0046] This invention features a material distribution component 7 within the groove. When the device cuts the knitting needle blank, excess knitting needle feet are removed and collected in the slag collection box 701 through the discharge port on the lower template 2. After the upper template 4 is cut, it is moved upward by the first hydraulic rod 11. At this time, the third hydraulic rod 702 pushes the push plate 703, causing the cut knitting needles to move through the discharge port 704 into the leveling component 8. This avoids material accumulation that could affect the operation of the device and also reduces the workload of the workers.

[0047] This invention includes a demolding component 6. Issues such as unsuitable mold material and surface roughness, poor processing material condition, insufficient lubrication, and excessive pressure and heat from the punch press may cause the needle blank to stick to the pressure plate 503 after cutting and fail to fall off automatically. This invention provides a pressure head 602 on the pressure plate 503. When cutting the needle blank, the pressure head 602 on the pressure plate 503 compresses the second spring 603, causing the slide rod 601 to retract into the groove of the pressure plate 503. After cutting, the pressure head 602 extends out of the groove due to the rebound force of the second spring 603, thus popping away any needle blanks that may be stuck to the surface of the pressure plate 503, thereby preventing the needle blank from sticking to the pressure plate 503 after cutting and failing to fall off automatically for collection.

[0048] This utility model is equipped with a leveling component 8. The push plate 703 causes the cut knitting needle to move through the discharge port 704 to the lower roller 801 in the leveling component 8. The lower roller 801 rotates and drives the knitting needle to move. When the knitting needle moves between the upper roller 804 and the lower roller 801, the upper roller 804 and the lower roller 801 will roll the knitting needle to prevent it from bending. At the same time, the distance between the upper roller 804 and the lower roller 801 can be adjusted by the second hydraulic rod 803, so that the device can roll knitting needles of different thicknesses.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
