DETAILED DESCRIPTION

[0018] As Figure 1 , Figure 2 and Figure 3 shown, the paper disc tension compensation device of the present application comprises a connecting plate 1, a swing arm head 2, a second guide rod 3, a first guide rod 4, a large bearing 5, a first rotating shaft 6, a locking nut 7, a compression spring 8, an L-shaped guide plate 9, a compression spring shaft 10, a tension spring 11, a fixed joint 12, a swing arm 14, a bearing seat 15, an adapter 16, and a first pin 17. The bearing seat 15 is fixed to the upper portion of the swing arm 14, the large bearing 5 is mounted in the bearing seat 15 and the swing arm 14, the end portion of the first rotating shaft 6 that passes through the swing arm 14 and the bearing seat 15 is threaded, the nut 18 cooperates with the above-mentioned thread to fix the first rotating shaft 6 on the swing arm 14 and the bearing seat 15, and the first rotating shaft 6 is fixed on the machine plate through the above-mentioned thread.

[0019] The first pin 17 passes through the end of the swing arm 14 and hinges the adapter 16 and the spring shaft 10 together. One end of the tension spring 11 is connected to the adapter 16 and the other end is connected to the fixed joint 12. The fixed joint 12 is fixed on the machine plate. One end of the spring shaft 10 passes through the other side of the L-shaped guide plate 9. One side of the L-shaped guide plate 9 is fixed on the machine plate. The spring 8 is fitted on one end of the spring shaft 10. One end of the spring 8 presses against the other side of the L-shaped guide plate 9. The other end of the spring 8 is fixed to the spring shaft 10 by the locking nut 7. The first guide wheel rod 4 is installed in the middle of the swing arm 14. The swing arm head 2 and the connecting plate 1 are installed at the lower end of the swing arm 14. The connecting plate 1 fixes the swing arm head 2 to the lower end of the swing arm 14 by fasteners. The second guide wheel rod 3 is installed on the swing arm head 2. The second guide wheel rod 3 and the first guide wheel rod 4 are parallel to each other.

[0020] like Figure 4 As shown, the second guide wheel rod 3 and the first guide wheel rod 4 include: a second rotating shaft 13, a spacer 19, a guide wheel rod outer sleeve 20, a small bearing 21, and a second pin 22. One end of the second rotating shaft 13 passes through the guide wheel rod outer sleeve 20. Two small bearings 21 spaced apart are mounted on the second rotating shaft 13 that passes through the guide wheel rod outer sleeve 20. The spacer 19 is fitted on the second rotating shaft 13 and is located between the two small bearings 21. The end of the second rotating shaft 13 that extends out of the guide wheel rod outer sleeve 20 has threads. The second rotating shaft 13 is fixed to the swing arm 14 or the swing arm head 2 through the threads. The end of the second rotating shaft 13 that does not extend out of the guide wheel rod outer sleeve 20 is fixed to one of the small bearings 21 by the second pin 22.

[0021] like Figure 5 and Figure 6 As shown, two connecting holes 24 are opened at the end of the swing arm 14, and two through holes 23 are opened on the swing arm head 2. The diameter of the through holes 23 is larger than the diameter of the connecting holes 24, so that the swing arm head 2 can be slightly adjusted relative to the swing arm 14.

[0022] 25 rolls of cigarette paper Figure 1 The first guide rod 25 enters the second guide rod 3 from the right side, passes around the second guide rod 3, enters the first guide rod 4 from the right side, and exits from the left side of the guide rod 4. Since the cigarette paper 25 will vibrate during the movement, the swing arm 14 will rotate around the first rotating shaft 6. In order to prevent its rotation amplitude from being too large, the compression spring 8 and the tension spring 11 can reduce the above-mentioned vibration. Since the diameter of the connecting hole 23 of the swing arm head 2 is larger than the connecting hole 24 of the swing arm 14, the position of the swing arm head 2 and the swing arm 14 can be slightly adjusted, reducing the tension of the cigarette paper 25.

[0023] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
