Abstract
Description

[0002] In the current existing technology, a layer of wrapping paper is put on the outer surface of the paper tube, and then the end of the wrapping paper is folded by relying on a folding mechanism. After folding, it is fixed by gluing or corresponding stickers. The folding mechanism is mainly composed of a ring-shaped bracket, a cylinder and a folding knife. The cylinder pushes the folding knife to push the outer wrapping paper to fold it. Another cylinder pushes the outer wrapping paper to fold and press it on the previous folding knife. The previous cylinder is reset to pull out the folding knife. After that, multiple cylinders repeat the above steps to bend the folding edge of the outer packaging. In order to be able to fold the edge, the outer packaging needs to extend a certain length from the end of the paper tube. The extended length has an important impact on whether the folding edge can be achieved and the consistency of the folding edge pattern.
[0003] However, during use, the length of the outer wrapping paper extending from the end of the paper tube may be inconsistent. If the outer wrapping paper extends longer or shorter, it will affect the folding edge of the paper tube packaging, thereby affecting the folding effect. Therefore, a paper tube packaging folding mechanism is proposed to address the above problem. Utility Model Content

[0022] Specific examples are given below.
[0023] See also Figure 1-5 As shown, a paper tube packaging folding mechanism includes a frame 11 and a base 18. The side of the frame 11 is fixedly connected to an annular frame 12, and a plurality of folding cylinders 13 are fixedly connected to the annular frame 12. The output end of the folding cylinder 13 is fixedly connected to a folding knife 14; the side of the base 18 is provided with a limit seat 61, the bottom of the base 18 is fixedly connected to a support 17, and the support 17 is fixedly connected to a rotating shaft 15. The rotating shaft 15 is rotatably connected to the top of the frame 11, and the side of the frame 11 is fixedly connected to a motor 16. The output end of the motor 16 is fixedly connected to the rotating shaft 15, and the side of the frame 11 is fixedly connected to a side push electric push rod 19. The limit seat 61 has a through hole on the side away from the base 18, and a sleeve 62 is fixedly connected to the side of the through hole away from the base 18. A push rod 63 is slidably connected to the inside of the sleeve 62; a second spring 64 is fixedly connected between the push rod 63 and the inner side wall of the sleeve 62;
[0024] When in use, the outer packaging paper is put on the paper tube and then placed inside the base 18, and then the motor 16 drives the rotating shaft 15 and the base 18 to rotate. The motor 16 is a servo motor 16, and the base 18 will rotate and tilt toward the limit seat 61, so that the paper tube and the outer packaging paper slide to one side and fit into the limit seat 61, so that the outer packaging paper and the paper tube are neatly arranged. At this time, the top rod 63 on the side of the limit seat 61 is aligned with the output end of the side push electric push rod 19, and then the side push electric push rod 19 can push the top rod 63 to move, and the top rod 63 passes through the through hole and is inserted into the outer packaging In the paper, the top end of the push rod 63 pushes the paper tube inside the outer packaging paper to move, so that the outer packaging paper extends a certain length longer than the paper tube, and then the side push electric push rod 19 is reset, and the motor 16 controls the base 18 to rotate and reset, and then multiple folding cylinders 13 push the folding to move, and push the folding to push the outer packaging paper to fold in turn, so as to complete the folding process of paper tube packaging. Relying on the above settings, the length of the outer packaging paper extending from the end of the paper tube can be adjusted, which can facilitate the folding of the paper tube packaging and improve the uniformity of the folding pattern.
[0025] Further, such as Figure 3-5 As shown, a fixed electric push rod 21 is installed on the side of the support 17 through a bracket, and the fixed electric push rod 21 is located at the top of the base 18. The output end of the fixed electric push rod 21 is fixedly connected to a horizontal plate 22, and a top seat 23 is provided at the bottom of the horizontal plate 22; a guide rod 4 is fixedly connected to the side of the support 17, and the guide rod 4 passes through the horizontal plate 22 and is slidably connected thereto, and the horizontal plate 22 can move along the guide rod 4; when in use, by providing the fixed electric push rod 21, the fixed electric push rod 21 can push the horizontal plate 22 to move downward, thereby driving the top seat 23 installed at the bottom of the horizontal plate 22 and the base 18 to close, so that the paper tube and the outer packaging paper can be confined between the base 18 and the top seat 23, thereby reducing the situation where the paper tube falls out of the base 18 when the base 18 rotates downward.
[0026] Further, such as Figure 3 As shown, the bottom of the support 17 is fixedly connected with a downward-moving electric push rod 31, and the output end of the downward-moving electric push rod 31 is fixedly connected to the limit seat 61. The bottom of the support 17 is fixedly connected with a vertical rod 32, and the vertical rod 32 passes through the limit seat 61 and is slidably connected thereto, and the limit seat 61 can move along the vertical rod 32; when in use, the support 17 can be driven to move downward by relying on the downward-moving electric push rod 31, and the vertical rod 32 passes through the support 17 and is slidably connected thereto, which can guide the downward movement of the support 17 to improve stability. When the support 17 moves downward, it can facilitate the folding electric push rod to fold the outer packaging paper during folding, thereby reducing the obstruction of the support 17 and increasing the operable space.
[0027] Further, such as Figure 3As shown, sliding holes 51 are provided at both ends of the top seat 23, and a fixed seat 52 is slidably connected inside the sliding hole 51. The top of the fixed seat 52 is fixedly connected to the cross plate 22, and a first spring 53 is fixedly connected between the cross plate 22 and the top seat 23; in this embodiment, the cross plate 22 is connected to the top seat 23 through the first spring 53, and the cross plate 22 pushes the top seat 23 and the base 18 to close through the first spring 53. After the paper tube position is adjusted, the fixed electric push rod 21 continues to push the cross plate 22 downward, thereby moving the fixed seat 52 downward, so that the bottom of the fixed seat 52 squeezes the outer packaging paper and the paper tube, so that they can be fixed, thereby reducing the movement of the paper tube during folding.
[0028] Further, such as Figure 3 As shown, the end of the push rod 63 close to the base 18 is tapered, and the outer packaging paper is prone to deformation and concavity, while the end of the push rod 63 is tapered, which makes it easy for the push rod 63 to be inserted into the inner part of the outer packaging paper, thereby facilitating its expansion and pushing the inner paper tube.
[0029] Working principle: when in use, put the outer wrapping paper on the paper tube and put it into the base 18, then the motor 16 drives the rotating shaft 15 and the base 18 to rotate. The motor 16 is a servo motor 16, and the base 18 will rotate and tilt toward the limit seat 61, so that the paper tube and the outer wrapping paper slide to one side and fit into the limit seat 61, so that the outer wrapping paper and the paper tube are neatly arranged. At this time, the top rod 63 on the side of the limit seat 61 is aligned with the output end of the side push electric push rod 19, and then the side push electric push rod 19 can push the top rod 63 to move, and the top rod 63 is inserted through the through hole. The paper tube 61 is inserted into the outer wrapping paper, and the top end of the push rod 63 pushes the paper tube inside the outer wrapping paper to move, so that the outer wrapping paper extends a certain length longer than the paper tube, and then the side push electric push rod 19 is reset, and the motor 16 controls the base 18 to rotate and reset, and then the multiple folding cylinders 13 push the folding to move, and push the folding to push the outer wrapping paper to fold in turn, so as to complete the folding process of paper tube packaging. Relying on the above arrangement, the length of the outer wrapping paper extending from the end of the paper tube can be adjusted, so that the folding of the paper tube packaging can be facilitated and the folding pattern can be improved. Uniformity, by setting a fixed electric push rod 21, the fixed electric push rod 21 can push the horizontal plate 22 to move downward, and then drive the top seat 23 installed at the bottom of the horizontal plate 22 and the base 18 to close, so that the paper tube and the outer packaging paper can be restricted between the base 18 and the top seat 23, thereby reducing the situation where the paper tube falls from the base 18 when the base 18 rotates downward, and the downward moving electric push rod 31 can drive the support 17 to move downward, and the vertical rod 32 passes through the support 17 and is slidably connected thereto, which can guide the support 17 to move downward to improve stability, and the support 17 moves downward. When folding, it can facilitate the folding electric push rod to fold the outer packaging paper, reduce the obstruction of the support 17, and increase the operable space. The cross plate 22 is connected to the top seat 23 through the first spring 53. The cross plate 22 pushes the top seat 23 and the base 18 to close through the first spring 53. After the paper tube position is adjusted, the fixed electric push rod 21 continues to push the cross plate 22 downward, thereby moving the fixed seat 52 downward, so that the bottom of the fixed seat 52 squeezes the outer packaging paper and the paper tube, so that they can be fixed, thereby reducing the movement of the paper tube during folding.
