Detailed Implementation

[0032] Example 1

[0033] like Figure 1-4 As shown, the present invention proposes a paper bowl machine bottom paper feeding device, which includes a mounting frame 1, a motor 9, a guide roller 10, a positioning component and an adjustment component;

[0034] The number of guide rollers 10 is at least one. The guide roller 10 is rotatably mounted at one end of the mounting frame 1. The side of the guide roller 10 and the other end of the mounting frame 1 are provided with a conveying assembly for conveying base paper of different thicknesses in the use state.

[0035] There are two positioning components, which are symmetrically arranged in the middle of the mounting bracket 1;

[0036] The adjustment component is installed in the middle of the mounting bracket 1 and inserted into the inner side of the top of the positioning component. The inner side of the adjustment component is provided with a bidirectional lead screw 11 for synchronously moving the two positioning components in use.

[0037] The motor 9 is mounted at the bottom of the mounting frame 1 and is connected to the conveying assembly for transmission.

[0038] In this embodiment, the guide roller 10 guides the bottom paper from between the two positioning components to the conveying component. At the same time, the bidirectional lead screw 11 is rotated by the adjusting component, so that the bidirectional lead screw 11 drives the two positioning components to move towards or relative to each other along the length direction of the adjusting component, thereby positioning the conveying position of the bottom paper to avoid the bottom paper from shifting and making the adjustment of the positioning components more convenient. Meanwhile, the conveying component clamps and fixes the bottom paper, and the motor 9 drives the conveying component to operate, so that the conveying component continuously conveys the bottom paper.

[0039] Example 2

[0040] like Figure 1-2 As shown, the present invention proposes a paper bowl machine bottom paper feeding device. Compared with the first embodiment, the difference in this embodiment is that the conveying component includes a telescopic rod 2, a transmission roller 3, and a connecting frame 4.

[0041] The number of telescopic rods 2 is at least two. The two telescopic rods 2 are respectively set on one side of the top of the mounting frame 1, and the extended end extends to the inside of the mounting frame 1. The telescopic rods 2 are one of hydraulic cylinders, air cylinders and electric telescopic rods.

[0042] The connecting bracket 4 is installed at the extended end of the telescopic rod 2;

[0043] There are two transmission rollers 3, which are rotatably mounted on the mounting frame 1 and the connecting frame 4, respectively.

[0044] In an optional embodiment, the two transmission rollers 3 are arranged overlapping in the vertical direction to clamp the bottom paper at the middle of the upper and lower ends of the two transmission rollers 3 during use, so that the bottom paper is transported smoothly and the bottom paper is prevented from bending.

[0045] In this embodiment, two transmission rollers 3 are rotatably mounted on the mounting frame 1 and the connecting frame 4 respectively, and the connecting frame 4 is moved down by the telescopic rod 2 to adjust the distance between the two transmission rollers 3, thereby enabling the transmission rollers 3 to support and clamp the bottom paper, and to clamp and transport bottom paper of different thicknesses between the two transmission rollers 3.

[0046] Example 3

[0047] like Figure 3 As shown, the present invention proposes a paper bowl machine bottom paper feeding device. Compared with the first embodiment, the difference in this embodiment is that the adjustment component includes a rotating handle 5, a mounting shell 6, and a slider 16.

[0048] Mounting housing 6 is installed in the middle of mounting bracket 1 and wraps around the outside of double-acting lead screw 11;

[0049] There are two sliders 16, and the two mounting shells 6 are symmetrically mounted on the inner side of the mounting shell 6 and sleeved on the outer side of the bidirectional lead screw 11 according to the center of the mounting shell 6.

[0050] The handle 5 is located at the end of the mounting housing 6 and is connected to the bidirectional lead screw 11. The handle 5 can also be replaced by a servo motor or a stepper motor for adjustment during use.

[0051] In this embodiment, the bidirectional lead screw 11 is driven to rotate in the mounting housing 6 by the rotating handle 5, and the bidirectional lead screw 11 drives the two sliders 16 to move relative to or towards each other on the inner side of the mounting housing 6, so that the two sliders 16 move synchronously, thereby driving the positioning component to move synchronously, making the position adjustment of the positioning component more convenient.

[0052] Example 4

[0053] like Figure 3-4As shown, the present invention proposes a paper bowl machine bottom paper feeding device. Compared with the first embodiment, the difference in this embodiment is that the positioning component includes a sleeve 7, a positioning plate 8, a second hand-tightening bolt 14, and an internal threaded tube 15.

[0054] The sleeve 7 is fitted onto the outside of the mounting shell 6 and its inner side is fitted and connected to the outside of the mounting shell 6.

[0055] The positioning plate 8 is installed at the bottom end of the sleeve 7 and is located at the end.

[0056] The internally threaded tube 15 is located below the sleeve 7 and on the side of the positioning plate 8;

[0057] The second hand-tightened bolt 14 is inserted into the inner side of the internal threaded tube 15 and connected to the through sleeve 7 and the slider 16.

[0058] In an optional embodiment, the bottom end of the slider 16 is provided with a threaded groove 17, and one end of the second hand-tightening bolt 14 is fitted into the threaded groove 17. When in use, the second hand-tightening bolt 14 is inserted into the threaded groove 17 in the internal threaded tube 15 and connected to the slider 16, so that the slider 16 drives the sleeve 7 to adjust its position through the second hand-tightening bolt 14. At the same time, the second hand-tightening bolt 14 is separated from the threaded groove 17, so that the sleeve 7 can slide freely on the outside of the mounting shell 6.

[0059] In an optional embodiment, a nut 12 is provided on the side of the sleeve 7, and a first hand-tightening bolt 13 is inserted into the inner side of the nut 12 to connect the nut 12 and the sleeve 7. When the sleeve 7 slides freely on the outside of the mounting shell 6, the first hand-tightening bolt 13 is used to apply pressure to the mounting shell 6 through the nut 12, thereby fixing the position of the sleeve 7, allowing the sleeve 7 to be adjusted in multiple directions, and allowing the sleeve 7 to drive the positioning plate 8 to adapt to the paper feeding at different positions.

[0060] In this embodiment, the second hand-tightening bolt 14 moves towards the threaded groove 17 inside the internal threaded tube 15 and connects the second hand-tightening bolt 14 with the slider 16, thereby connecting the sleeve 7 with the slider 16. At the same time, the slider 16 drives the sleeve 7 to adjust its position, so that the sleeve 7 drives the positioning plate 8 to position the bottom paper.

[0061] In this invention, the second hand-tightening bolt 14 moves from the inner side of the internal threaded tube 15 to the threaded groove 17, connecting the second hand-tightening bolt 14 to the slider 16 through the threaded groove 17, thereby connecting the sleeve 7 to the slider 16. Simultaneously, the rotating handle 5 drives the bidirectional lead screw 11 to rotate in the mounting shell 6, causing the bidirectional lead screw 11 to drive the two sliders 16 to move relative to or towards each other inside the mounting shell 6, so that the two sliders 16 move synchronously. The sliders 16 also drive the sleeve 7 to move synchronously through the second hand-tightening bolt 14, and the sleeve 7 drives the positioning plate 8 to position the bottom paper. At the same time, the guide roller 10 guides the bottom paper from between the two positioning plates 8 to the transmission roller 3, and the telescopic rod 2 drives the connecting frame 4 to descend, causing the connecting frame 4 to drive the transmission roller 3 to clamp the bottom paper. Simultaneously, the motor 9 drives one transmission roller 3 to rotate, and through downward pressure, the two transmission rollers 3 rotate synchronously, thereby enabling the two transmission rollers 3 to continuously transport the bottom paper.

[0062] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
