[0002] In cigarette manufacturing, tipping paper is a key material that connects the filter tip to the main body of the cigarette. The tipping paper is conveyed to the tipping station, where a limiting structure is used to limit the tipping paper to precisely control its conveying path and positioning, prevent it from deviating or becoming misaligned, and ensure accurate connection between the tipping paper and the cigarette.
[0003] In the existing technology, a fixed limiting block is used to limit the connection paper. The limiting block structure can only be used for connection papers of a specific size. If the size of the connection paper does not match the limiting block, a new limiting block needs to be disassembled and replaced. The operation and adjustment steps are complicated, time-consuming and labor-intensive.
[0004] In other words, the existing fixed limiting blocks have the disadvantage that they can only be used for splicing paper of a specific size and cannot be used for splicing paper of different specifications. Utility Model Content

[0040] like Figures 1 to 7 As shown, this embodiment provides a paper splicing limiting device, which includes a carrier 10, a screw 20, and an adjusting member 30. The carrier 10 is provided with a limiting groove 13. One side of the carrier 10 is used to support the paper splicing. The screw 20 is rotatably connected to the other side of the carrier 10. There are two adjusting members 30. The screw 20 is threadedly connected to the two adjusting members 30. The limiting groove 13 corresponds to the adjusting members 30 one by one. The first end of each adjusting member 30 protrudes from one side of the carrier 10, and the second end passes through the limiting groove 13 and is connected to the screw 20. The paper splicing is located between the first ends of the two adjusting members 30. The rotation of the screw 20 drives the two adjusting members 30 to slide in the limiting groove 13 to move closer or further away from each other.
[0041] By setting a carrier 10, and setting a screw 20 and two adjusting members 30 on the carrier 10, the splicing paper is placed on the carrier 10 and located between the first ends of the two adjusting members 30. The second end of the adjusting member 30 passes through the limiting slide groove 13 to be threadedly connected to the screw 20. The limiting slide groove 13 restricts the movement direction of the adjusting member 30. When the screw 20 is rotated, the two adjusting members 30 are driven to slide in the corresponding limiting slide groove 13 to move closer or further away from each other, thereby changing the distance between the two adjusting members 30 to adapt to different sizes of splicing paper. There is no need to disassemble the splicing paper limiting device, and the operation steps are simple and convenient.
[0042] See Figure 2 and Figure 3 Specifically, the support member 10 includes a support body 11 and a limiting end plate 12. The support body 11 has a groove 111, and the limiting end plate 12 is detachably fixed to the support body 11. The limiting end plate 12 and the support body 11 together form a limiting slide groove 13 at the groove 111. By setting a detachable support body 11 and limiting end plate 12, the limiting end plate 12 can be removed from the support body 11, and the adjusting member 30 can be placed directly at the groove 111. Then, the limiting end plate 12 is fixed to the support body 11. The limiting end plate 12 and the support body 11 together form a limiting slide groove 13 at the groove 111. The limiting end plate 12 restricts the extreme position of the adjusting member 30 and facilitates disassembly and maintenance.
[0043] Optionally, the paper receiving limiting device further includes a first fastener 41. One end of the first fastener 41 abuts against the limiting end plate 12, and the other end of the first fastener 41 passes through the limiting end plate 12 and is threadedly connected to the bearing body 11. By using the first fastener 41 to fix the limiting end plate 12 to the bearing body 11, the limiting end plate 12, the bearing body 11, and the groove 111 together form a limiting slide groove 13. The connection between the limiting end plate 12 and the bearing body 11 is convenient and reliable, allowing for quick installation and facilitating subsequent maintenance and replacement.
[0044] In this embodiment, each limiting end plate 12 is fixed to the bearing seat 11a by two first fasteners 41; the two first fasteners 41 are arranged side by side at intervals along the Y direction; the first fasteners 41 can be screws. In other embodiments, the bearing body 11 and the limiting end plate 12 can also be set as an integral structure.
[0045] Furthermore, the supporting body 11 includes a supporting seat 11a and a screw seat 11b. A groove 111 is provided in the supporting seat 11a, and the supporting seat 11a and the limiting end plate 12 form a limiting slide groove 13 at the groove 111. One side of the supporting seat 11a is used to support the receiving paper, and the screw seat 11b is detachably fixed to the other side of the supporting seat 11a. The screw 20 is rotatably connected to the screw seat 11b. By providing a detachable supporting seat 11a and screw seat 11b, during installation, the screw 20 can be first installed on the screw seat 11b, and then the screw 20 and the screw seat 11b can be fixed together on the supporting seat 11a, which facilitates the maintenance and replacement of the screw 20 and the screw seat 11b.
[0046] Specifically, the X direction is the length direction of the support 11a, the Y direction is the width direction of the support 11a, and the Z direction is the height direction of the support 11a; the screw 20 extends along the X direction and has two sections of threads with opposite directions for connection to two adjusting members 30 respectively, and the two adjusting members 30 are spaced apart along the X direction; the two limiting end plates 12 are the first limiting end plate 12a and the second limiting end plate 12b respectively, and the support 11a has grooves 111 on both ends of the support 11a along the X direction. The support 11a is located between the first limiting end plate 12a and the second limiting end plate 12b. The first limiting end plate 12a and the second limiting end plate 12b respectively form a limiting slide groove 13 with the support 11a at the corresponding grooves 111; the first end of the adjusting member 30 protrudes from the support 11a and the second end passes through the limiting slide groove 13 along the Z direction and is connected to the screw 20.
[0047] In this embodiment, the screw seat 11b is fixed to the bearing seat 11a by the second fastener 42; there are two second fasteners 42 spaced apart along the Y direction; the second fastener 42 is a screw.
[0048] See Figure 1 and Figure 4Optionally, the support 11a is provided with a through vent 112. The vent 112 forms a first opening on one side of the support 10 and a second opening on the other side of the support 10. The second opening is used to connect with the air pump through the air duct and form a negative pressure system so that the first opening can adsorb the splicing paper.
[0049] By providing a vent 112 on the support 11a, and connecting a vacuum pump through a duct via a second opening at one end of the vent 112, while the first opening at the other end is used to adsorb the tipping paper, the negative pressure adsorption force is used to adsorb the tipping paper, which can reduce the lateral offset and shaking of the tipping paper. This method is applicable to tipping papers of different materials and thicknesses, reducing positioning deviations caused by differences in tipping paper materials. In this embodiment, the vent 112 penetrates the support 11a along the Z direction.
[0050] Furthermore, the adjusting member 30 is provided with a protrusion 311, and the bearing member 10 is provided with a mounting groove 113 on one side. The extending direction of the mounting groove 113 is parallel to the extending direction of the limiting slide groove 13. The protrusion 311 is inserted into the mounting groove 113. The rotation of the screw 20 drives the adjusting member 30 to move, thereby causing the protrusion 311 to slide within the mounting groove 113. By providing a protrusion 311 on the adjusting member 30 and a mounting groove 113 on the bearing member 10, the relative movement direction of the adjusting member 30 and the bearing member 10 can be further restricted by the cooperation of the protrusion 311 and the mounting groove 113, and the position of the adjusting member 30 can be restricted, thus preventing positional deviation of the adjusting member 30 during movement.
[0051] See Figure 1 and Figure 3 The support 11a is provided with a mounting groove 113. Both the mounting groove 113 and the limiting slide groove 13 extend along the X direction, and the mounting groove 113 and the limiting slide groove 13 are spaced apart along the Y direction. There are two limiting slide grooves 13 spaced apart along the X direction, and there are also two mounting grooves 113 spaced apart along the X direction. See also Figures 4 to 7 The adjusting member 30 includes a limiting part 31 and a connecting part 32, which are connected as one unit. The limiting part 31 protrudes from one side of the bearing seat 11a, and the connecting part 32 passes through the limiting slide groove 13 and is connected to the screw 20. The limiting part 31 is provided with a protrusion 311, which is spaced apart from the connecting part 32 along the Y direction.
[0052] In this embodiment, the adjusting member 30 is T-shaped; the two adjusting members 30 are the first adjusting member 30a and the second adjusting member 30b, respectively. The first adjusting member 30a and the second adjusting member 30b are respectively inserted into the corresponding limiting slide groove 13, and the protrusions 311 on the first adjusting member 30a and the second adjusting member 30b respectively cooperate with the two mounting grooves 113.
[0053] Furthermore, the paper feeding limiting device also includes an elastic element 50. A limiting ring surface 2111 is provided on the screw 20. Both the elastic element 50 and the limiting ring surface 2111 correspond one-to-one with the adjusting element 30. The elastic element 50 is sleeved on the screw 20, with its two ends abutting against the limiting ring surface 2111 and the adjusting element 30, respectively. By installing the elastic element 50 on the screw 20, the elastic force of the elastic element 50 provides axial pressure to eliminate the thread engagement gap between the adjusting element 30 and the screw 20, thus preventing loosening.
[0054] In this embodiment, there are two elastic elements 50 and two limiting ring surfaces 2111. The two limiting ring surfaces 2111 are located between the two adjusting elements 30. Each limiting ring surface 2111 has an elastic element 50 on the side close to the adjusting element 30. The elastic element 50 is a spring.
[0055] Optionally, the screw 20 is provided with a limiting ring 211, and two limiting rings 211 are provided at intervals. The portion of the screw 20 located between the two limiting rings 211 is rotatably connected to the carrier 10. By providing the limiting rings 211 on the screw 20, the accurate rotational connection position between the screw 20 and the carrier 10 can be ensured.
[0056] In this embodiment, the screw 20 includes a first section 21 and two second sections 22. The first section 21 is connected to a second section 22 at both ends. Two limiting rings 211 are spaced apart on the first section 21. The part of the first section 21 located between the two limiting rings 211 is rotatably connected to the screw seat 11b. The two limiting rings 211 have a limiting ring surface 2111 on the side opposite to each other. The second section 22 is used for threaded connection with the adjusting member 30.
[0057] Optionally, the limiting end plate 12 is provided with a mounting hole 121, and the end of the screw 20 passes through the adjusting member 30 and is rotatably inserted into the mounting hole 121. By providing a mounting hole 121 on the limiting end plate 12, the end of the screw 20 is inserted into the mounting hole 121, and the screw 20 can rotate within the mounting hole 121, which can limit the relative position of the adjusting member 30 and the screw 20, and further ensure the stability of the screw 20 installation.
[0058] In this embodiment, both the first limiting end plate 12a and the second limiting end plate 12b are provided with mounting holes 121, and the positions of the mounting holes 121 on the first limiting end plate 12a and the second limiting end plate 12b match the positions of the screw 20; the second segment 22 of the screw 20 is rotatably inserted into the mounting hole 121.
[0059] Optionally, the splicing paper limiting device also includes an operating rod 60, which is detachably inserted into the insertion hole 221 at the end of the screw 20. Rotation of the operating rod 60 drives the screw 20 to rotate. By setting the operating rod 60 and inserting it into the insertion hole 221 at the end of the screw 20, the rotation of the operating rod 60 drives the screw 20 to rotate, thereby adjusting the distance between the two adjusting members 30 to accommodate splicing papers of different sizes. This method is convenient, reliable, and durable. In this embodiment, one end of the screw 20 has an insertion hole 221, which is hexagonal. The shape of the end of the operating rod 60 matches the shape of the insertion hole 221.
[0060] The paper splicing limiting device provided in this embodiment drives two adjusting members 30 to slide within the corresponding limiting grooves 13 by rotating the screw 20, so that the two adjusting members 30 can quickly and accurately finely adjust and position the paper splicing, which is suitable for the production needs of paper splicing of different sizes.
[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
