Description

Technical Field

[0001] The utility model relates to the technical field of button tape cutting devices, in particular to a button tape fixed-length cutting device. Background Art

[0002] The button tape consists of a tape body and buttons. During production, the buttons are first crimped onto a whole tape body, and then cut to a fixed length. Due to the material characteristics of the tape body, if ordinary cutters or scissors are used for cold cutting, the ends of the tape body will have problems with running lines or tangled lines. Therefore, buttons need to be cut by electric heating. Electric heating cutting generally uses a heating wire as a cutter to heat-melt the tape body through the heating wire to achieve cutting, and then a hot-melt edging effect is produced on the cut surface, thus preventing the problem of tangled lines.

[0003] Currently, button tapes are cut to length manually. During cutting, workers measure the cutting length, hold both ends of the button tape, and then place the button tape on a thermal cutting machine with a heating wire to achieve cutting using the heat of the heating wire.

[0004] However, the efficiency of this cutting method depends entirely on the physical strength of the workers. As the working time increases and the physical strength is consumed, the work efficiency will gradually decrease. At the same time, the length of the button tape is also completely controlled by manpower. After operating for a period of time, visual fatigue will occur, and at this time, there will be large errors in the control of the cutting length.

[0005] Therefore, it is impossible to maintain a stable work efficiency and quality for a long time when cutting is performed by manpower. At the same time, the entire cutting process is completed manually, and its mechanization level is low.

[0006] Therefore, there is an urgent need for a button tape fixed-length cutting device to ensure the efficiency and quality of button tape cutting and realize mechanized fixed-length cutting.

[0007] A meter counter is an electronic device constructed from a number of electronic components that can measure length. It features strong anti-interference capabilities, high precision, reliability, ease of use, and clear readings. It is widely used in industries such as papermaking, printing, textiles, rubber, and plastics for displaying and controlling length, quantity, and flow.

[0008] The main components of a mechanical meter counter include a counting wheel, a counting nut (encoder), an input lever, and a display assembly. When the button on the input lever is pressed, the counting wheel and counting nut begin to rotate. Each rotation of the counting wheel represents an increase in length or distance by one unit. Simultaneously with the rotation of the counting wheel, the pointer in the display assembly also rotates, pointing to the corresponding number, indicating the measured length or distance.

[0029] The present invention will be described clearly and completely below with reference to the embodiments.

[0030] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0031] In the description of the embodiments, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, connections through an intermediary medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on their specific circumstances.

[0032] See attached Figure 1-5 The figure shows a fixed-length cutting device for button tape, comprising a support frame 1, a feeding plate 2 is mounted on the support frame 1, and a feeding channel 3 is opened on the feeding plate 2 along the length direction. The width of the feeding channel 3 can accommodate the width of the tape body 29, and the entire button tape is placed in the feeding channel 3 during cutting, and the feeding channel 3 provides a guiding effect for the entire button tape. At the same time, the feeding channel 3 is provided with a receiving groove 14 corresponding to the position of the button 30, and the receiving groove 14 can accommodate the width and thickness of the button 30, ensuring that the tape body 29 is placed in the material channel 3 in a horizontal state. At the same time, in order to prevent the button tape from running out of the material channel 3 during the overall feeding, the feeding plate 2 is provided with a pressing plate 24 on both sides of the material channel 3, and a feeding gap 25 is provided between the pressing plate 24 and the feeding plate 2, and the feeding gap 25 can accommodate the thickness of the tape body 29. When placing the button tape, the tape body 29 is placed in the feeding gap 25, and the feeding gap 25 reduces the jumping amplitude of the button tape during feeding.

[0033] A driving unit is provided at one end of the feeding plate 2 along the feeding direction, wherein the driving unit includes wheel frames 4 arranged on both sides of the material channel 3, and each wheel frame 4 is independently configured with a driving motor 5, and a driving wheel 6 is provided at the output end of the driving motor 5. The outer wall of the driving wheel 6 is provided with an anti-slip protrusion, and the distance between the two driving wheels 6 is greater than the overall width of the button 30, so as to avoid interference between the driving wheel 6 and the button 30. When feeding, the button 30 is placed in the material channel 3, and then the driving wheel 6 is pressed on the belt body 29, and the driving motor 5 drives the driving wheel 6 to The button belt 30 is driven forward as a whole by friction. At the same time, a loading platform 10 is provided at one end of the feeding plate 2 close to the receiving plate 13. The length of the loading platform 10 is not more than 30 mm. The loading platform 10 enables the button belt 30 to remain in a horizontal state after coming out of the material channel 3 to prevent it from sagging immediately under the action of gravity. At the same time, the length of the loading platform 10 is set to be no more than 30 mm. Since the rigidity of the belt body 29 itself is extremely low, when the length of the loading platform 10 is too long, it will accumulate itself, thereby preventing normal feeding;

[0034] Furthermore, a plurality of guide posts 7 are provided on the top of the wheel frame 4, and an inverted L-shaped bracket 8 is provided at one end of the feeding plate 2 close to the wheel frame 4. A guide hole is provided at the position of the inverted L-shaped bracket 8 corresponding to the guide post 7. A threaded hole is provided at the center of the inverted L-shaped bracket 8. An adjusting bolt 9 is provided in the threaded hole. One end of the adjusting bolt 9 is rotatably connected to the wheel frame 4. In addition, a spring is provided between the feeding plate 2 and the wheel frame 4. When in use, the pressure between the driving wheel 6 and the belt body 29 can be adjusted by adjusting the bolt 9, thereby changing the friction between the two to ensure normal feeding.

[0035] Furthermore, a length measuring device 26 is provided on the feed plate 2. Specifically, the length measuring device 26 is a mechanical meter counter, which includes a meter wheel and a counting nut. The counting nut functions as an encoder 28. When in use, the meter wheel is abutted against one side of the belt body 29. When the belt body 29 moves, the meter wheel is driven to rotate. At this time, the value on the counting nut will change accordingly and be displayed through the display device, and the length of the feed material is finally obtained.

[0036] As a button tape fixed-length cutting device, the support frame 1 is provided with a support plate 11 at one end of the driving unit, and a material receiving frame 12 is provided on the support plate 11. A material receiving plate 13 is provided on the material receiving frame 12. The material receiving plate 13 is lower than the material loading platform 10, and a cutting gap is left between the material receiving plate 13 and the material loading platform 10 so that the heating wire 21 can pass through. The width of the cutting gap is 2 mm. When the button 30 comes out of the loading platform 10, it will smoothly transition to the material receiving plate 13 under the action of its own gravity. At the same time, the material receiving plate 13 is provided with an equal-width connecting groove 15 at the position corresponding to the accommodating groove 14. The button 30 can continue to be accommodated through the connecting groove 15 to avoid the problem of the button 30 leaning upward on the material receiving plate 13.

[0037] Furthermore, the support plate 11 is provided with a displacement unit between the driving unit and the receiving frame 12. The displacement unit includes two columns 17. A slide rail 18 is provided on the side where the two columns 17 are close to each other. A slider 19 is provided on the slide rail 18. The slider 19 is provided with a resistor 20. The heating wire 21 is connected to the resistor 20. A connecting beam 22 is provided between the two sliders 19. A driving cylinder 23 is provided on the support plate 11. The output end of the driving cylinder 23 is connected to the connecting beam 22. When the running length of the button tape reaches the set length during cutting, the driving cylinder 23 drives the heating wire 21 to move downward to achieve cutting of the tape body 29.

[0038] It can be seen that during cutting, the driving motor 5 drives the driving wheel 6 to use friction to drive the button tape 30 to move along the material channel 3. At the same time, the length of the button tape is monitored in real time by the length measuring device 26 during movement. When the set length is reached, the driving cylinder 23 is used to drive the heating wire 21 to achieve cutting. In this process, mechanical cutting replaces manual cutting, which improves the degree of mechanization and also ensures the quality and efficiency of cutting.

[0039] Finally, in order to ensure the directionality of the button tape on the receiving plate 13 and avoid the problem of beveling, the receiving plate 13 is provided with guide plates 16 on both sides of the connecting groove 15, and the two guide plates 16 are trumpet-shaped.

[0040] During cutting, first place the belt body 29 in the feeding gap 25, and place the button 30 in the receiving groove 14, so that the belt body 29 is placed between the two driving wheels 6 and the feeding plate 2. When fixed-length cutting is performed, the driving motor 5 is used to drive the driving wheel 6 to rotate, and the driving wheel 6 further uses friction to drive the entire button 30 belt forward as a whole and transition from the loading platform 10 to the receiving plate 13. At this time, the counting wheel 27 will rotate under the friction of the belt body 29, and the feeding length will be displayed through the counting nut. When the feeding length reaches the set length, the driving cylinder 23 is used to drive the heating wire 21 to move downward to achieve cutting.

[0041] The above description is only a preferred specific embodiment of the present invention and does not limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
