A connecting block is rotatably connected to the side of the connecting plate away from the upper roller. A spring is fixedly connected to the top of the connecting block. A mounting plate is fixedly connected to the top of the spring. A rotating shaft is rotatably connected between the two mounting plates. A handle is fixedly connected to the rear side of the rotating shaft. A main reversing roller is provided on the rear side of the base plate. A connecting frame is provided at the left end of the main reversing roller. The left end of the main reversing roller moves through the connecting frame and is fitted with a clamping nut. Two reversing roller seats are movably fitted on the outside of the main reversing roller. Two auxiliary reversing rollers are provided between the two reversing roller seats. The two ends of the auxiliary reversing rollers move through the two reversing roller seats.

[0006] As a preferred embodiment of this utility model, the first sensor is located near the bottom of the vertical rod, and the paper tape limiting ring is located above the first sensor.

[0007] As a preferred embodiment of this utility model, a drive shaft is fixedly installed through the inner cavity of the lower roller. The two ends of the drive shaft are rotatably connected to two support plates respectively, and the right end of the drive shaft is connected to the power output end of the motor.

[0008] As a preferred embodiment of this utility model, a first screw is inserted into the front side of the paper stop rod near both ends, and the first screw is threaded onto the support plate. A fifth screw is inserted into the rear side of the horizontal plate near both the left and right sides, and the fifth screw is threaded onto the support plate.

Detailed Implementation

[0015] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Example like Figures 1 to 10As shown, a paper cup machine's bottom paper pulling mechanism includes: a base plate 1, a vertical rod 2 installed near the left side of the bottom of the base plate 1, a paper tape limiting ring 3 and a first sensor 4 installed on the vertical rod 2, the first sensor 4 being near the bottom end of the vertical rod 2, the paper tape limiting ring 3 being located above the first sensor 4, a motor 5 installed near the right side of the top of the base plate 1, two support plates 6 installed near the left side of the top of the base plate 1, a lower roller 7 being provided between the two support plates 6, a drive shaft 8 being fixedly inserted through the inner cavity of the lower roller 7, the two ends of the drive shaft 8 being rotatably connected to the two support plates 6 respectively, the right end of the drive shaft 8 being connected to the power output end of the motor 5, an upper roller 11 being provided above the lower roller 7, a paper stop bar 9 being provided on the front side of the upper roller 11, and a first screw 10 being inserted into the front side of the paper stop bar 9 near both ends, the first screw 10 being threadedly connected to the support plate 6.

[0017] The paper tape is passed under the paper stop bar 9, which serves as a guide to prevent the paper tape from curling up. Then the paper tape passes through the paper tape limiting ring 3. Under the action of gravity, the paper tape falls to the front of the first sensor 4. The function of the paper tape limiting ring 3 is to prevent the paper tape from swaying left and right, so that the first sensor 4 can obtain a signal.

[0018] Finally, the paper tape is connected to the next station, causing it to rise slowly. Once the paper tape has risen far away from the first sensor 4, the motor 5 starts working. The motor 5 drives the lower roller 7 to rotate via the drive shaft 8, and begins to feed the paper tape. When the paper tape is used up, the second sensor 30 loses its signal, the motor 5 stops working, and the worker is reminded that the paper roll has been used up and a new paper roll needs to be replaced.

[0019] In this embodiment, a horizontal plate 29 is provided on the rear side of the upper roller 11, and a second sensor 30 is installed on the rear side of the horizontal plate 29. Fifth screws 31 are inserted into the rear side of the horizontal plate 29 near both the left and right sides, and are threaded onto the support plate 6. A main reversing roller 24 is provided on the rear side of the bottom plate 1, and a connecting frame 22 is provided at the left end of the main reversing roller 24. Two third screws 23 are movably inserted into the left side of the connecting frame 22, and are threaded onto the support plate 6. A clamping nut 25 is fitted against the left side wall of the connecting frame 22, and the clamping nut 25 is threaded onto the main reversing roller 24. The main reversing roller 24 has an external thread on its left outer side, which matches the clamping nut 25. The left end of the main reversing roller 24 passes through the connecting frame 22 and is fitted with the clamping nut 25. Two reversing roller seats 26 are movably fitted on the outer side of the main reversing roller 24. Two auxiliary reversing rollers 28 are provided between the two reversing roller seats 26. The two ends of the auxiliary reversing rollers 28 pass through the two reversing roller seats 26. Three fourth screws 27 are threadedly connected to the top of the reversing roller seats 26. The three fourth screws 27 are respectively in contact with the main reversing roller 24 and the two auxiliary reversing rollers 28.

[0020] Adjust the distance between the two reversing roller seats 26 according to the width of the paper tape. Loosen the fourth screw 27 to release the fixing of the reversing roller seat 26. Then move the reversing roller seat 26. The reversing roller seat 26 moves outside the main reversing roller 24 and the auxiliary reversing roller 28. After the distance between the two reversing roller seats 26 is adjusted, tighten the fourth screw 27 to fix the reversing roller seat 26. The two reversing roller seats 26 can prevent the paper tape from swaying left and right.

[0021] Pass the paper tape through the bottom of the two auxiliary reversing rollers 28, and simultaneously through the top of the main reversing roller 24. You can also loosen the clamping nut 25 to release the main reversing roller 24, then rotate the main reversing roller 24 and adjust the angle of the reversing roller pivot 26 to adjust the paper tape feed angle. After adjustment, tighten the clamping nut 25 to fix the main reversing roller 24.

[0022] In this embodiment, connecting plates 12 are rotatably connected to both the left and right sides of the upper roller 11. A connecting block 13 is rotatably connected to the side of the connecting plate 12 away from the upper roller 11. A slot 21 is provided on the top of the support plate 6. The connecting block 13 is slidably connected to the inner cavity of the slot 21. A spring 14 is fixedly connected to the top of the connecting block 13. A mounting plate 19 is fixedly connected to the top of the spring 14. Two second screws 20 are inserted into the top of the mounting plate 19. The second screws 20 are threadedly connected to the top of the support plate 6. A rotating shaft 15 is rotatably connected between the two mounting plates 19. A handle 16 is fixedly connected to the rear side of the rotating shaft 15. A through hole 17 is provided on the connecting plate 12. Two grooves 18 are provided on the top of the rotating shaft 15. The rotating shaft 15 moves through the two through holes 17. The inner wall of the through hole 17 fits against the inner wall of the groove 18.

[0023] By rotating the shaft 15 forward by the handle 16, the shaft 15 rotates 90 degrees. When the shaft 15 rotates, the groove 18 moves away from the perforation 17. At this time, the inner wall of the perforation 17 is in contact with the outer side of the shaft 15. The connecting plate 12 moves upward, and the connecting plate 12 drives the upper roller 11 to move upward. The upper roller 11 drives the connecting block 13 to move upward. At the same time, the spring 14 is compressed. At this time, the distance between the upper roller 11 and the lower roller 7 increases, and the paper tape passes through the space between the upper roller 11 and the lower roller 7. Then, the shaft 15 is flipped down, so that the groove 18 is in contact with the inner wall of the perforation 17. The upper roller 11 moves downward under the action of gravity and the elasticity of the spring 14. The upper roller 11 presses the paper tape tightly against the lower roller 7.

[0024] Implementation plan: During use, first adjust the distance between the two reversing roller seats 26 according to the width of the paper tape, loosen the fourth screw 27 to release the fixation of the reversing roller seat 26, and then move the reversing roller seat 26. The reversing roller seat 26 moves outside the main reversing roller 24 and the auxiliary reversing roller 28. After the distance between the two reversing roller seats 26 is adjusted, tighten the fourth screw 27 to fix the reversing roller seat 26. The two reversing roller seats 26 can prevent the paper tape from swaying left and right.

[0025] Pass the paper tape through the bottom of the two auxiliary reversing rollers 28, and simultaneously through the top of the main reversing roller 24. You can also loosen the clamping nut 25 to release the main reversing roller 24, then rotate the main reversing roller 24 and adjust the angle of the reversing roller pivot 26 to adjust the paper tape feed angle. After adjustment, tighten the clamping nut 25 to fix the main reversing roller 24.

[0026] By rotating the shaft 15 forward by the handle 16, the shaft 15 rotates 90 degrees. When the shaft 15 rotates, the groove 18 moves away from the perforation 17. At this time, the inner wall of the perforation 17 is in contact with the outer side of the shaft 15. The connecting plate 12 moves upward, and the connecting plate 12 drives the upper roller 11 to move upward. The upper roller 11 drives the connecting block 13 to move upward. At the same time, the spring 14 is compressed. At this time, the distance between the upper roller 11 and the lower roller 7 increases, and the paper tape passes through the space between the upper roller 11 and the lower roller 7. Then, the shaft 15 is flipped down, so that the groove 18 is in contact with the inner wall of the perforation 17. The upper roller 11 moves downward under the action of gravity and the elasticity of the spring 14. The upper roller 11 presses the paper tape tightly against the lower roller 7.

[0027] Then, the paper tape is passed under the paper stop bar 9. The paper stop bar 9 serves as a guide to prevent the paper tape from curling up. Then, the paper tape passes through the paper tape limiting ring 3. Under the action of gravity, the paper tape falls to the front of the first sensor 4. The function of the paper tape limiting ring 3 is to prevent the paper tape from swaying left and right, so that the first sensor 4 can obtain a signal.

[0028] Finally, the paper tape is connected to the next station, causing it to rise slowly. Once the paper tape has risen far away from the first sensor 4, the motor 5 starts working. The motor 5 drives the lower roller 7 to rotate via the drive shaft 8, and begins to feed the paper tape. When the paper tape is used up, the second sensor 30 loses its signal, the motor 5 stops working, and the worker is reminded that the paper roll has been used up and a new paper roll needs to be replaced.

[0029] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
