Description

Technical Field

[0001] The present invention relates to the technical field of correction tape assembly, and particularly to a correction tape assembly machine. Background Art

[0002] A correction tape is a white opaque pigment. Through its unique winding and unwinding structure, the pigment is applied to paper to cover miswritten words, and writing can be immediately resumed on it, providing convenience for learning and work.

[0003] The structure of the correction tape can be divided into a base, an upper cover, a large gear, a take-up wheel, a nozzle, and a tape core. At present, the assembly of the correction tape is generally manually completed. First, the tape core needs to be sleeved on the large gear, then the end of the tape on the tape core is pulled out, then the tape is wound around the nozzle, and then the end of the tape is adhered to the take-up wheel. Then, the large gear and the take-up wheel are rotated several times to wind the end of the tape around the take-up wheel. Then, the large gear, the take-up wheel, and the nozzle can be pressed into the base, and finally, the upper cover is aligned and closed with the base. The operation steps of the whole process are numerous, and the working efficiency of manual operation is low. Moreover, when people wind the tape around the nozzle and adhere it to the take-up wheel, the large gear, the take-up wheel, and the nozzle are all held by hand, lacking positioning, and the installation difficulty is large. In addition, finally, the large gear and the take-up wheel need to be rotated several times, and at this time, the tape will move on the nozzle, easily causing the nozzle to shift or fall off, affecting the overall installation efficiency. Summary of the Invention

A conveying mechanism is provided on the lifting assembly. A pressing assembly is provided on the conveying mechanism. A pushing assembly is provided on the lifting assembly.

[0027] As Figure 1 shown, the lifting assembly includes a first electric push rod 4 and a mounting frame 5. The first electric push rod 4 is bolted to the rear side of the top of the bottom plate 1. The telescopic rod of the first electric push rod 4 is connected with a mounting frame 5. The first motor 6 is installed on the left side of the bottom of the mounting frame 5.

[0028] As Figure 2 shown, the rotating assembly includes a second motor 7 and a rotating frame 8. The second motor 7 is bolted to the right side of the bottom of the mounting frame 5. The lower right side of the mounting frame 5 is rotatably connected with a rotating frame 8. The rotating frame 8 is located in front of the second motor 7. The third motor 9 is installed on the left side of the rotating frame 8. The rotating frame 8 and the output shaft of the second motor 7 are driven by a worm and a worm gear.

[0029] As Figure 2 and Figure 3As shown in the figure, the conveying mechanism includes a fourth electric push rod 10, a fourth motor 11, a connecting rod 12, a mounting block 13, a first conveyor belt 14, a rotating arm 15, a brushless motor 16, a screw rod 17, a moving block 18 and a return spring 19. The left side of the bottom of the mounting frame 5 is bolted with a fourth electric push rod 10. The fourth electric push rod 10 is located in front of the first motor 6. The telescopic rod of the fourth electric push rod 10 is connected with a fourth motor 11. The output shaft of the fourth motor 11 is connected with a connecting rod 12. The lower part of the right side of the connecting rod 12 is connected with a mounting block 13. The first conveyor belt 14 is rotatably mounted on the outside of the mounting block 13. The self-rotation of the first conveyor belt 14 can tear the end of the strip. The left side of the top of the mounting block 13 is rotatably connected with a rotating arm 15. A brushless motor 16 is mounted on the right side of the rotating arm 15. The brushless motor 16 is in contact with the first conveyor belt 14. The upper part of the mounting block 13 is threadedly connected with a screw rod 17. A moving block 18 is threadedly connected to the screw rod 17. A return spring 19 is connected between the moving block 18 and the rotating arm 15.

[0030] As Figure 4 shown in the figure, the pressing assembly includes a connecting frame 20 and a second conveyor belt 21. The connecting frame 20 is welded to the front side of the mounting block 13. The second conveyor belt 21 is rotatably mounted on the connecting frame 20. The rear side of the second conveyor belt 21 is in contact with the front side of the first conveyor belt 14. The cooperation between the second conveyor belt 21 and the first conveyor belt 14 can convey the end of the strip to the take-up wheel to the right.

[0031] As Figure 2 and Figure 5 shown in the figure, the pushing assembly includes a connecting block 22, a sleeve rod 23, a second electric push rod 24 and a pushing rod 25. The connecting block 22 is welded to the right side of the bottom of the mounting frame 5. The middle of the connecting block 22 is connected with a sleeve rod 23. The rotation of the rotating frame 8 can drive the take-up wheel to rotate, so that the strip bypasses the sleeve rod 23. The left side of the connecting block 22 is bolted with a second electric push rod 24. The telescopic rod of the second electric push rod 24 is connected with a pushing rod 25. The pushing rod 25 slides on the outside of the sleeve rod 23. When the pushing rod 25 moves downward, it can push the strip wound around the sleeve rod 23 downward and wind it around the nozzle.

[0032] Initially, the first conveyor belt 14 is in a straight state. First, control the intermittent operation of the material conveyor 2, which can drive the limit block 3 to move intermittently to the right. Then, the operator can put the belt core on the large gear, and then install the large gear, the take-up wheel and the pressing nozzle on the base. Then, place the base on the conveyor belt of the material conveyor 2. One set of limit blocks 3 can limit the base, and the limit block 3 can drive the base to move intermittently to the right. When the base moves to directly below the clamping head 61, the base stops moving. At this time, the mounting bracket 5 can be driven to move downward by the first electric push rod 4, driving the first motor 6, the clamping head 61 and the third motor 9 to move downward. The two clamping heads 61 will respectively insert into the central positions of the large gear and the take-up wheel and clamp the large gear and the take-up wheel. Then, drive the mounting bracket 5 to move upward by the first electric push rod 4, and the large gear and the take-up wheel can be driven to move upward by the clamping head 61. Then, drive the connecting rod 12 to rotate backward by the fourth motor 11, driving the mounting block 13 and the first conveyor belt 14 to rotate backward. The right side of the first conveyor belt 14 will be squeezed by the take-up wheel and bend, so that it can closely adhere to the surface of the take-up wheel, making the first conveyor belt 14 tensioned, and the left side of the first conveyor belt 14 can closely adhere to the surface of the belt core. Then, drive the first conveyor belt 14 to rotate self by the brushless motor 16. Under the action of friction, the second conveyor belt 21 can be driven to rotate self. Then, drive the clamping head 61 to rotate by the first motor 6 and the third motor 9, which can drive the large gear and the take-up wheel to rotate. The large gear drives the belt core to rotate. At this time, the left side of the first conveyor belt 14 can tear the end of the tape on the belt core, and clamp the end of the tape and move to the right through the first conveyor belt 14 and the second conveyor belt 21, making the end of the tape contact with the take-up wheel. The second conveyor belt 21 can press the end of the tape on the surface of the take-up wheel, making the end of the tape adhere to the surface of the take-up wheel. The rotation of the take-up wheel can wind up a part of the end of the tape. Then, control the clamping head 61 to stop rotating, and then drive the fourth motor 11 to move upward by the fourth electric push rod 10, which can drive the first conveyor belt 14 and the second conveyor belt 21 to move upward and separate from the tape. Then, drive the rotating frame 8 to rotate 360 degrees by the second motor 7, which can drive the third motor 9 to rotate 360 degrees, thereby driving the end of the tape to rotate around the sleeve rod 23, making the tape wind around the sleeve rod 23. Then, drive the mounting bracket 5 to move downward by the first electric push rod 4, driving the clamping head 61 and the sleeve rod 23 to move downward, so as to drive the large gear, the take-up wheel and the belt core to move downward, making the large gear and the take-up wheel installed on the base, and the sleeve rod 23 can be aligned with the pressing nozzle. At this time, drive the push rod 25 to move downward by the second electric push rod 24, and the push rod 25 can push the tape wound around the sleeve rod 23 downward, making the tape wind around the pressing nozzle, completing the assembly work of the correction tape. Then, control the clamping head 61 to release the large gear and the take-up wheel. The material conveyor 2 can continue to convey the assembled correction tape to the right. The operator can take out the assembled correction tape and align and close the upper cover and the base. Repeat the above operations to automatically assemble the correction tape.After the first conveyor belt 14 reciprocates between tension and relaxation, the first conveyor belt 14 may become loose. At this time, the screw 17 can be rotated to drive the moving block 18 to move forward. The rotating arm 15 can be pulled to swing forward through the return spring 19, thereby driving the brushless motor 16 to move forward to press against the first conveyor belt 14, preventing the first conveyor belt 14 from becoming loose. The return spring 19 plays a buffering role.

[0033] As Figure 6 shown, it further includes a third electric push rod 26 and a positioning block 27. The third electric push rods 26 are symmetrically bolted to the front and back of the middle of the top of the bottom plate 1. The positioning blocks 27 are connected to the telescopic rods of the third electric push rods 26. When the base moves to directly below the clamping head 61, the third electric push rod 26 can be used to drive the positioning blocks 27 towards the side where they approach each other, so that the positioning blocks 27 fix the front and back sides of the base, thereby being able to position the base and prevent the base from shifting.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
