[0004] In the existing technology, there is a gap between the pressing structure and the shearing blade. When the existing device is conveying some softer material strips, one end of the material strip may fall off the guide roller and get stuck in the gap due to gravity, thus affecting the cutting operation of the tape cutter. Utility Model Content

[0005] The purpose of this invention is to provide a feeding guide structure for a computer-controlled tape cutting machine, which solves the problem in the prior art that when one end of the tape leaves the guide roller, it may fall and get stuck in the gap due to gravity.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A feeding guide structure for a computer-controlled tape cutting machine includes a tape cutting machine body, a placement frame fixedly connected to the rear end of the tape cutting machine body, and a feeding assembly provided on the top of the tape cutting machine body. The feeding assembly includes a feeding trough, a first guide trough, a roller, a pressing plate, a second guide trough, auxiliary rollers, transmission rollers, and a stepper motor.

[0008] Preferably, the output end of the stepper motor is connected to the transmission roller, the side surface of the transmission roller is tangent to the side surface of the auxiliary roller, and the second guide groove is V-shaped.

[0009] Preferably, a support frame is fixedly connected to the top of the tape cutting machine body, an electric push rod is fixedly installed on the top of the support frame, and a lifting groove is opened inside the support frame.

[0010] Preferably, a push rod is slidably connected inside the lifting groove, and a cutting blade is fixedly connected to the bottom of the push rod. The telescopic end of the electric push rod passes through the inside of the lifting groove and is fixedly connected to the push rod.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Reference Figure 1-5 A feeding guide structure for a computer-controlled tape cutting machine includes a tape cutting machine body 1, a placement frame 2 fixedly connected to the rear end of the tape cutting machine body 1, and a feeding assembly 3 disposed on the top of the tape cutting machine body 1. The feeding assembly 3 includes a feeding trough 301, a first guide trough 302, a roller 303, a pressing plate 304, a second guide trough 305, an auxiliary roller 306, a transmission roller 307, and a stepper motor 308. The feeding trough 301 is located on the top of the tape cutting machine body 1, the first guide trough 302 is located at the bottom of the feeding trough 301, and the roller 303... The first guide trough 302 is rotatably connected inside, the pressing plate 304 is rotatably connected inside the feeding trough 301, the second guide trough 305 is opened at the bottom of the feeding trough 301, the auxiliary rollers 306 are rotatably connected to the inner wall of the second guide trough 305 in a symmetrical arrangement, the transmission rollers 307 are rotatably connected inside the second guide trough 305, the stepper motor 308 is fixedly connected to the top of the tape cutter body 1, and the side of the roller 303 is equipped with a baffle to limit the material strip and prevent the material strip from shifting during movement.

[0025] The output end of the stepper motor 308 is connected to the transmission roller 307. The side surface of the transmission roller 307 is tangent to the side surface of the auxiliary roller 306. The second guide trough 305 is V-shaped. With the setting of the feeding component 3, when the tape cutter body 1 is working, the tape first passes through the inside of the first guide trough 302 and contacts the surface of the roller 303. Then the tape moves to the bottom of the pressing plate 304 and is pressed to flatten the tape and prevent it from sticking up. Then the tape enters the inside of the second guide trough 305. Since the second guide trough 305 is V-shaped, the tape will fold from both sides to the middle in a V-shape. Finally, the stepper motor 308 drives the rotation of the transmission roller 307, which drives the V-shaped tape to move. This not only enables safe and stable feeding of the tape, but also increases the support of the tape during the folding process, preventing the tape from falling into the cut during the conveying process, effectively improving the safety of the tape and the work efficiency of the workers.

[0026] Furthermore, a support frame 4 is fixedly connected to the top of the main body 1 of the tape cutter, an electric push rod 5 is fixedly installed on the top of the support frame 4, and a lifting groove 6 is opened inside the support frame 4.

[0027] A push rod 7 is slidably connected inside the lifting groove 6. A cutting blade 8 is fixedly connected to the bottom of the push rod 7. The telescopic end of the electric push rod 5 passes through the inside of the lifting groove 6 and is fixedly connected to the push rod 7. By activating the electric push rod 5, the telescopic end of the electric push rod 5 drives the push rod 7 to move up and down inside the lifting groove 6. When the push rod 7 moves up and down, it can complete the cutting of the material strip.

[0028] Furthermore, a pressing strip 3041 is fixedly connected to the side of the pressing plate 304 near the second guide groove 305, a pressing strip 3042 is fixedly connected to the side of the pressing plate 304 near the second guide groove 305 and between the pressing strips 3041, and connecting columns 3043 are fixedly connected to the left and right sides of the pressing plate 304 in a symmetrical manner.

[0029] A support block 3044 is rotatably connected to the side surface of the connecting column 3043. A support plate 3045 is fixedly connected to the side surface of the connecting column 3043 and above the support block 3044. A helical spring 3046 is fixedly connected to the bottom of the support plate 3045. The second pressing strip 3042 extends into the interior of the second guide groove 305. The support block 3044 is fixedly connected to the cutter body 1. The other end of the helical spring 3046 is fixedly connected to the cutter body 1. When the material strip passes through the pressing plate 304... Since the height of the conveyor belt itself supports the pressing plate 304, the spring force of the helical spring 3046 can drive the pressing plate 304 to press the conveyor belt firmly, which not only improves the stability of the conveyor belt, but also increases the adaptability to conveyor belts of different heights. When the conveyor belt passes through the second pressing bar 3042 and the first pressing bar 3041, since the second pressing bar 3042 extends into the interior of the second guide groove 305, it will drive the conveyor belt to enter the interior of the second guide groove 305 in a V-shape.

[0030] Furthermore, the placement rack 2 has a positioning slot 201 inside, and a limiting block 202 is fixedly connected inside the positioning slot 201. A feeding tray 203 is placed inside the positioning slot 201, and a positioning groove 204 is opened on the side surface of the feeding tray 203. Before the tape cutting machine body 1 performs tape cutting operation, the operator first installs the feeding tray 203 containing the tape inside the positioning slot 201. Then, because the limiting block 202 is engaged with the positioning groove 204, the feeding tray 203 is limited, which effectively improves the safety and stability of the feeding tray 203 when conveying the tape.

[0031] In summary:

[0032] When in use, the staff first installs the feeding tray 203 containing the material belt inside the positioning slot 201. Then, the limiting block 202 engages with the positioning slot 204, thereby limiting the feeding tray 203.

[0033] Next, the material strip passes through the inside of the first guide groove 302 and contacts the surface of the roller 303, so that the roller 303 presses and stretches the material strip. Then the material strip moves to the bottom of the pressing plate 304 and is pressed to flatten the material strip and prevent it from sticking out. Then the material strip will enter the inside of the second guide groove 305. Since the second guide groove 305 is V-shaped, the material strip will fold from both sides to the middle in a V-shape. Finally, the stepper motor 308 drives the rotation of the transmission roller 307, which drives the V-shaped material strip to move.

[0034] Finally, the electric push rod 5 is activated, causing the telescopic end of the electric push rod 5 to drive the push rod 7 to move up and down inside the lifting groove 6. When the push rod 7 moves up and down, it can complete the cutting of the material strip.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
