Description

Technical Field

[0001] This utility model relates to the technical field of tobacco processing equipment, and in particular to a packaging machine inner frame paper positioner and packaging machine. Background Technology

[0002] The inner frame paper refers to a layer of paper used in the cigarette packaging manufacturing process to position the cigarette box lid and provide support for the cigarette pack. In cigarette packaging, the inner frame paper not only protects the cigarettes but also plays an important role in aesthetics and anti-counterfeiting.

[0003] In the cigarette pack production process, the inner frame paper, after being cut, conveyed, and positioned, is transported to the cigarette box along with the aluminum foil cigarette pack. During this process, the inner frame paper is positioned using a positioner to ensure its consistent position within the aluminum foil cigarette pack, facilitating subsequent processing. Currently, commonly used positioners are non-adjustable damping type, and their installation height is fixed, resulting in a fixed contact height. These positioners have extremely high requirements for material thickness; fluctuations in material thickness often lead to inaccurate positioning or blockage of the inner frame paper. For example, if the material thickness decreases, because it is less than the standard value, the positioner cannot contact the inner frame paper, causing the inner frame paper to vibrate or shift during conveying, making stable and accurate positioning impossible and thus rendering the positioning inaccurate. When the material thickness increases, because the material thickness is greater than the standard value, although the inner frame paper can achieve accurate positioning, the positioning thickness of the positioner is less than the thickness of the inner frame paper, resulting in greater frictional resistance. This causes the inner frame paper to be unable to move forward with the aluminum foil cigarette pack, which will cause the inner frame paper to become blocked or torn at this point.

[0004] Therefore, there is an urgent need for a packaging machine inner frame paper positioner and a packaging machine to solve the above problems. Utility Model Content

[0005] The first objective of this utility model is to provide a packaging machine inner frame paper positioner to solve the problems of inaccurate positioning of the inner frame paper, or blockage and tearing of the inner frame paper, when the thickness of the inner frame paper is inconsistent due to the fixed contact height of the positioner in the prior art.

[0006] The second objective of this invention is to provide a packaging machine that improves the accuracy of positioning the inner frame paper and avoids problems such as inaccurate positioning or blockage and tearing of the inner frame paper during the conveying process.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A packaging machine inner frame paper positioner is installed on the guide plate of the packaging machine, the guide plate being located at the top of the inner frame paper conveying channel. The packaging machine inner frame paper positioner includes:

[0009] The positioning body has a second threaded section on its outer peripheral side, which is used to connect to the threaded hole of the guide plate.

[0010] A positioning element is inserted into the positioning body. The positioning element is movable along the height direction of the positioning body. One end of the positioning element has a first threaded section, and the other end of the positioning element is connected to an abutment. The abutment is located below the positioning body and can abut against the positioning body.

[0011] A first fixing nut is adjustablely connected to the first threaded section. The first fixing nut is located above the positioning body and can abut against the positioning body.

[0012] The second fixing nut is connected to the second threaded section and is located above the guide plate.

[0013] Furthermore, the abutment is conical, and the large end of the abutment is connected to the other end of the positioning member, and the large end can abut against the positioning body.

[0014] Furthermore, the axis of the abutment member coincides with the axis of the positioning member.

[0015] Furthermore, there are two second fixing nuts, one of which is located above the guide plate and the other is located below the guide plate.

[0016] Furthermore, in the height direction of the positioning body, the positioning body has a circular through hole, and the positioning element is cylindrical and passes through the circular through hole.

[0017] Furthermore, the positioning member has a guide protrusion on its side, and a guide groove is formed on the inner wall of the circular through hole along the axial direction of the circular through hole. The guide groove extends to both ends of the circular through hole, and the guide protrusion can slide along the extension direction of the guide groove.

[0018] Furthermore, multiple guide protrusions are evenly spaced along the circumference of the positioning member, and multiple guide grooves are evenly spaced along the circumference of the circular through hole, with each guide protrusion and guide groove corresponding to the other.

[0019] Furthermore, the end of the positioning body away from the abutment is provided with a chamfer.

[0020] A packaging machine includes a guide plate and an inner frame paper positioner, wherein the inner frame paper positioner is installed in a threaded hole in the guide plate.

[0021] Furthermore, the packaging machine has multiple inner frame paper positioners, and the guide plate has multiple threaded holes, with each of the multiple inner frame paper positioners corresponding to one of the multiple threaded holes.

[0022] The beneficial effects of this utility model are:

[0023] This utility model provides an inner frame paper positioner for a packaging machine, installed on the guide plate of the packaging machine, with the guide plate located at the top of the inner frame paper conveying channel. The inner frame paper positioner includes a positioning body, a positioning element, a first fixing nut, and a second fixing nut. A second threaded section is provided on the outer periphery of the positioning body, which is used to connect to a threaded hole in the guide plate. The positioning element passes through the positioning body and can move along the height direction of the positioning body. One end of the positioning element has the first threaded section, and the other end is connected to an abutment element located below the positioning body and capable of abutting against it. The first fixing nut is adjustablely connected to the first threaded section, located above the positioning body, and capable of abutting against it. The second fixing nut is connected to the second threaded section and located above the guide plate. With the above configuration, the abutment is located below the positioning body and within the inner frame paper conveying channel. During the conveying of the inner frame paper, the abutment abuts against the paper, positioning it within the conveying channel. Vertically, the first fixing nut is adjustablely connected to the first threaded section and abuts against the positioning body. Since the abutment is located at the other end of the positioning body, its height within the conveying channel is adjustable, and it can move vertically. When the abutment contacts the positioning body, it is at its highest position; when the first fixing nut abuts against the positioning body... When positioning the main body, the abutting part is in the lowest position. The abutting part can move in both the lowest and highest positions, meaning the abutting height of the inner frame paper positioner of the packaging machine is adjustable. When the abutting part contacts inner frame paper of different thicknesses, it can move in both the lowest and highest positions, maintaining its abutting position against the inner frame paper for positioning. This ensures that the abutting part can maintain its abutting position against the inner frame paper regardless of its thickness, avoiding inaccurate positioning of the inner frame paper and preventing problems such as clogging or tearing of the inner frame paper, thus guaranteeing the stability of the positioning of the inner frame paper.

[0024] This utility model also provides a packaging machine, including a guide plate and the aforementioned inner frame paper positioner. The inner frame paper positioner is installed in the threaded hole of the guide plate. The contact height of the inner frame paper positioner is adjustable. When the contacting part contacts inner frame paper of different thicknesses, the contacting part can move at the lowest and highest positions, maintaining contact with the inner frame paper to position it. That is, for inner frame paper of different thicknesses, the contacting part can maintain contact with the inner frame paper, avoiding inaccurate positioning of the inner frame paper, and preventing problems such as blockage and tearing of the inner frame paper, thus ensuring the stability of the positioning of the inner frame paper.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0033] This utility model provides a packaging machine inner frame paper positioner that can maintain contact with the inner frame paper of different thicknesses, avoiding inaccurate positioning of the inner frame paper, and preventing problems such as clogging and tearing of the inner frame paper, thus ensuring the stability of the positioning of the inner frame paper.

[0034] It should be noted that the inner frame paper positioner of the packaging machine is installed on the guide plate of the packaging machine, and the guide plate is located at the top of the inner frame paper conveying channel.

[0035] In this embodiment, as Figure 1As shown, the inner frame paper positioner of the packaging machine includes a positioning body 4, a positioning component 1, a first fixing nut 2, and a second fixing nut 3. The outer periphery of the positioning body 4 is provided with a second threaded section, which is used to connect to the threaded hole of the guide plate. The positioning component 1 passes through the positioning body 4 and can move along the height direction of the positioning body 4. One end of the positioning component 1 has the first threaded section, and the other end of the positioning component 1 is connected to an abutment 5. The abutment 5 is located below the positioning body 4 and can abut against the positioning body 4. The first fixing nut 2 is adjustablely connected to the first threaded section. The first fixing nut 2 is located above the positioning body 4 and can abut against the positioning body 4. The second fixing nut 3 is connected to the second threaded section and is located above the guide plate. With the above configuration, the abutment 5 is located below the positioning body 4 and within the inner frame paper conveying channel. During the conveying of the inner frame paper, the abutment 5 abuts against the inner frame paper, positioning it within the conveying channel. Vertically, the first fixing nut 2 is adjustablely connected to the first threaded section and abuts against the positioning body 4. Since the abutment 5 is located at the other end of the positioning member 1, its height within the conveying channel is adjustable, and it can move vertically. When the abutment 5 contacts the positioning body 4, it is at its highest position. When the first fixing nut 2... When the abutting part 5 is in contact with the positioning body 4, it is in the lowest position. The abutting part 5 can move in both the lowest and highest positions, meaning that the abutting height of the inner frame paper positioner of the packaging machine is adjustable. When the abutting part 5 contacts inner frame paper of different thicknesses, it can move in both the lowest and highest positions, maintaining contact with the inner frame paper and positioning it. In other words, for inner frame paper of different thicknesses, the abutting part 5 can maintain contact with the inner frame paper, avoiding inaccurate positioning of the inner frame paper and preventing problems such as blockage or tearing of the inner frame paper, thus ensuring the stability of positioning the inner frame paper.

[0036] It should be noted that the contact height of the inner frame paper positioner of the packaging machine refers to the height of the contact part 5 relative to the bottom of the conveying channel, that is, the thickness of the inner frame paper that the contact part 5 can position. Different inner frame papers have different thicknesses, and the adjustable contact height of the inner frame paper positioner of the packaging machine can meet the positioning requirements of inner frame papers of different thicknesses.

[0037] For example, the abutment 5 is conical, with its large end connected to the other end of the positioning member 1, and the large end able to abut against the positioning body 4. It is understood that while the large end of the abutment 5 is connected to the other end of the positioning member 1, the small end of the abutment 5 can abut against the inner frame paper. Because the abutment 5 is conical, the connecting surface between the large and small ends of the abutment 5 is curved, which facilitates the guidance of the movement of the abutment 5 when it contacts the inner frame paper, allowing the abutment 5 to move upwards and for the small end of the abutment 5 to smoothly abut against the inner frame paper. The specific dimensions of the abutment 5 can be determined according to actual usage requirements; this embodiment does not impose specific limitations. Of course, in other embodiments, the abutment 5 can also be frustum-shaped, with the abutment 5 inverted and connected to the other end of the positioning member 1, i.e., the large end of the abutment 5 is connected to the other end of the positioning member 1.

[0038] Furthermore, the axis of the abutment 5 coincides with the axis of the positioning element 1. It can be understood that by aligning the abutment 5 and the positioning element 1, when the abutment 5 contacts the inner frame paper, the abutment 5 moves upward, thereby driving the positioning element 1 to move. The axes of the two coincide, ensuring that there is no deviation in the axial thrust on the positioning element 1, thus making the movement smooth.

[0039] In this embodiment, two second fixing nuts 3 are provided, one of which is located above the guide plate and the other is located below the guide plate. It can be understood that by providing two second fixing nuts 3 located on the upper and lower sides of the guide plate respectively, the positioning body 4 is stably fixed to the guide plate, thereby stably installing the entire inner frame paper positioner of the packaging machine onto the guide plate.

[0040] Furthermore, in the height direction of the positioning body 4, a circular through hole is provided in the positioning body 4, and the positioning element 1 is cylindrical and passes through the circular through hole. It can be understood that by providing a circular through hole and a cylindrical positioning element 1, the positioning element 1 can reciprocate within the positioning body 4, thereby improving the smoothness of the movement of the positioning element 1.

[0041] Furthermore, the positioning element 1 has a guide protrusion on its side. A guide groove is formed on the inner wall of the circular through hole along its axial direction, extending to both ends of the circular through hole. The guide protrusion can slide along the extension direction of the guide groove. It can be understood that by providing a guide protrusion on the side of the positioning element 1 and a corresponding guide groove on the inner wall of the circular through hole, the movement of the positioning element 1 is easily guided, allowing it to move smoothly within the circular through hole.

[0042] Furthermore, multiple guide protrusions are evenly spaced along the circumference of the positioning member 1, and multiple guide grooves are evenly spaced along the circumference of the circular through hole, with each guide protrusion and groove corresponding to the other. It is understood that by providing multiple corresponding guide protrusions and guide grooves, the movement of the positioning member 1 can be further guided, thus improving the smoothness of its movement. In this embodiment, three guide protrusions and three guide grooves are provided. Of course, in other embodiments, the number of guide protrusions and guide grooves can also be other, such as two or four.

[0043] Furthermore, the end of the positioning body 4 furthest from the abutment part 5 is chamfered. Understandably, the chamfer facilitates the installation of the first fixing nut 2 by the operator.

[0044] This embodiment also provides a packaging machine that improves the accuracy of positioning the inner frame paper and avoids problems such as inaccurate positioning or blockage and tearing of the inner frame paper during the conveying process.

[0045] For example, the packaging machine includes a guide plate and the aforementioned inner frame paper positioner, which is installed in the threaded hole of the guide plate. It is understood that the contact height of the inner frame paper positioner is adjustable. When the contact member 5 contacts inner frame paper of different thicknesses, the contact member 5 can move at its lowest and highest positions, maintaining contact with the inner frame paper to position it. That is, for inner frame paper of different thicknesses, the contact member 5 can maintain contact with the inner frame paper, avoiding inaccurate positioning of the inner frame paper and preventing problems such as clogging or tearing of the inner frame paper, thus ensuring the stability of the inner frame paper positioning.

[0046] Furthermore, the packaging machine has multiple inner frame paper positioners, and the guide plate has multiple threaded holes, with each inner frame paper positioner corresponding to one of the multiple threaded holes. It can be understood that by setting multiple inner frame paper positioners, different inner frame paper can be positioned simultaneously during the inner frame paper conveying process, thus improving the conveying efficiency of the inner frame paper.

[0047] 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. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
