Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco manufacturing technology, and in particular to a conveying auxiliary pressure device. Background Technology
[0002] Cigarette pack conveying equipment typically uses fixed pressure roller assemblies on the conveyor belt. Cigarette packs are continuously transported by the conveyor belt below, and the pressure roller assembly increases friction during transport. In existing technology, simply adjusting the distance between the pressure rollers and the cigarette packs to change the clamping force usually requires manual intervention. However, cigarette packs are relatively soft and vary in thickness, so a single clamping force can easily leave indentations on the surface, making it impossible to flexibly adjust the clamping effect according to the specific transport conditions. Furthermore, excessive pressure can create greater resistance on the bottom conveyor belt, causing it to operate under heavy load for extended periods, leading to damage, deformation, and elongation, which is detrimental to the stable operation of the cigarette pack conveying equipment. Utility Model Content
[0003] The purpose of this utility model is to provide a conveying auxiliary pressure device that can effectively protect the conveyor belt, adaptively balance and adjust the pressure to ensure continuous conveying of cigarette packs, and has a simple assembly structure.

[0008] The active support leg section away from the active adjustment section and the driven support leg section away from the driven adjustment section are respectively provided with auxiliary pressure rollers. The auxiliary pressure rollers are used to press down on the tobacco pack located on the conveyor belt and directly below the auxiliary pressure rollers.
[0009] The active support leg section near the active adjustment section and the driven support leg section near the driven adjustment section are respectively rotatably connected to the mounting base; a portion of the active adjustment section and a portion of the driven adjustment section are overlapped along the extension direction perpendicular to the mounting base, and the active adjustment section and the driven adjustment section are movably connected.
[0010] The end of the active support leg section away from the active adjustment section is close to the conveyor belt. The rotation of the active rod can drive the driven rod to rotate relative to it, so that the end of the driven support leg section away from the driven adjustment section is close to the conveyor belt, thereby increasing the pressure of the auxiliary pressure roller of the driven support leg section on the tobacco pack.
[0011] The end of the active support leg section away from the active adjustment section is away from the conveyor belt. The rotation of the active rod can drive the driven rod to rotate relative to it, so that the end of the driven support leg section away from the driven adjustment section is away from the conveyor belt, thereby reducing the pressure of the auxiliary pressure roller of the driven support leg section on the tobacco pack.
[0012] As an optional technical solution for the conveying auxiliary pressure device, the active adjustment section is provided with a sliding member, the driven adjustment section is provided with a sliding groove, and the sliding member is movably inserted into the sliding groove.
[0013] As an optional technical solution for the conveying auxiliary pressure device, the outer periphery of the sliding member is fitted with a roller, and the roller is slidably embedded in the sliding groove.
[0014] As an optional technical solution for the conveying auxiliary pressure device, the sliding groove is configured as an elongated through groove.
[0015] As an optional technical solution for the conveying auxiliary pressure device, the active rod further includes an active bending section, the active adjustment section, the active bending section and the active support section are connected in sequence, the active adjustment section and the active support section are set at a preset angle, and the height of the active adjustment section is lower than the mounting base;
[0016] The driven rod also includes a driven bending section. The driven adjustment section, the driven bending section and the driven support leg section are connected in sequence. The driven adjustment section and the driven support leg section are set at a preset angle. The height of the driven adjustment section is lower than that of the mounting base.
[0017] As an optional technical solution for the conveying auxiliary pressure device, the mounting base is provided with a limiting component, and the upper surface of the active adjustment section selectively abuts against the limiting component.
[0018] As an optional technical solution for the conveying auxiliary pressure device, the limiting member is movably disposed on the mounting base in the vertical direction.
[0019] As an optional technical solution for the conveying auxiliary pressure device, the projections of the active support leg section and the driven support leg section on the horizontal plane are both located on the same straight line parallel to the extension direction of the mounting base; the opposite surfaces of the active adjustment section and the driven adjustment section are respectively provided with assembly steps, and the step surfaces of the two assembly steps are spaced apart by a preset distance.
[0020] As an optional technical solution for the conveying auxiliary pressure device, the linkage unit further includes a pressure roller assembly. The pressure roller assembly includes a pressure roller collection plate and auxiliary pressure rollers. The pressure roller assembly is provided in two sets. One pressure roller collection plate is rotatably connected to the end of the active support leg section away from the active adjustment section in a vertical plane, and the other pressure roller collection plate is rotatably connected to the end of the driven support leg section away from the driven adjustment section in a vertical plane. Multiple auxiliary pressure rollers are symmetrically arranged on both sides of the rotating shaft of the pressure roller collection plate.
[0021] As an optional technical solution for the conveying auxiliary pressure device, the auxiliary pressure roller is configured as a flexible roller.
[0022] The beneficial effects of this utility model are:
[0023] The conveying auxiliary pressure device provided by this utility model includes a mounting base and a linkage unit. The mounting base is parallel to and located above the conveyor belt. The driving rod of the linkage unit includes a connected driving support segment and a driving adjustment segment, and the driven rod includes a connected driven support segment and a driven adjustment segment. The driving adjustment segment and the driven adjustment segment are overlapped and movably connected along the extension direction perpendicular to the mounting base. One end of the driving support segment near the driving adjustment segment and one end of the driven support segment near the driven adjustment segment are respectively rotatably connected to the mounting base, and the other end of each segment is provided with an auxiliary pressure roller. The auxiliary pressure roller is used to press against the cigarette pack located on the conveyor belt and directly below the auxiliary pressure roller. The auxiliary pressure roller can always be in contact with the surface of the cigarette pack by its own weight. When there are cigarette packs under both auxiliary pressure rollers, the two auxiliary pressure rollers can simultaneously supply pressure to the cigarette pack, and the linkage structure can achieve the effect of balanced pressure, and the pressure can be adaptively balanced and adjusted.
[0024] When the end of the active support leg section furthest from the active adjustment section approaches the conveyor belt, the active rod rotates, causing the active adjustment section to drive the driven rod to rotate relative to it, bringing the end of the driven support leg section furthest from the driven adjustment section closer to the conveyor belt. This increases the pressure of the auxiliary pressure roller of the driven support leg section on the tobacco pack. Conversely, when the end of the active support leg section furthest from the active adjustment section moves away from the conveyor belt, the active rod rotates, causing the active adjustment section to drive the driven rod to rotate relative to it, moving the end of the driven support leg section furthest from the driven adjustment section away from the conveyor belt. This decreases the pressure of the auxiliary pressure roller of the driven support leg section on the tobacco pack. This conveyor auxiliary pressure device can self-balancely press the continuously accumulating tobacco packs onto the bottom conveyor belt, preventing stress accumulation on the bottom conveyor belt, effectively protecting its service life. Furthermore, it has a simple structure, is easy to maintain, and enables continuous and uninterrupted conveying of tobacco packs. Attached Figure Description

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.
[0035] like Figure 1 and Figure 2 As shown, this utility model discloses a conveying auxiliary pressure device, including a mounting base 100 and a linkage unit 200. The mounting base 100 is parallel to and located above the conveyor belt 300. The linkage unit 200 includes an active rod 210 and a driven rod 220 arranged sequentially along the conveying direction of the conveyor belt 300. The active rod 210 includes a connected active support leg section 211 and an active adjustment section 212. The driven rod 220 includes a connected driven support leg section 221 and a driven adjustment section 222. An auxiliary pressure roller 230 is respectively provided at the end of the active support leg section 211 away from the active adjustment section 212 and the end of the driven support leg section 221 away from the driven adjustment section 222. The auxiliary pressure roller 230 is used to press against the cigarette pack 400 located on the conveyor belt 300 and directly below the auxiliary pressure roller 230. The active support segment 211 near the active adjustment segment 212 and the driven support segment 221 near the driven adjustment segment 222 are respectively rotatably connected to the mounting base 100; a portion of the active adjustment segment 212 and a portion of the driven adjustment segment 222 are overlapped along the extension direction perpendicular to the mounting base 100, and the active adjustment segment 212 and the driven adjustment segment 222 are movably connected.
[0036] Under normal circumstances, the auxiliary pressure rollers 230 located on the active rod 210 and the driven rod 220 can always be in contact with the surface of the tobacco pack 400 by their own weight. When there is a tobacco pack 400 under both auxiliary pressure rollers 230, the two auxiliary pressure rollers 230 can supply pressure to the tobacco pack 400 at the same time, and the pressure can be balanced through the linkage structure. The pressure can be adaptively balanced and adjusted without the need for precise adjustment.
[0037] Specifically, when the end of the active support segment 211 away from the active adjustment segment 212 approaches the conveyor belt 300, the active rod 210 rotates so that the active adjustment segment 212 can drive the driven rod 220 to rotate relative to it, so that the end of the driven support segment 221 away from the driven adjustment segment 222 approaches the conveyor belt 300, increasing the pressure of the auxiliary pressure roller 230 of the driven support segment 221 on the tobacco pack 400. Conversely, when the end of the active support segment 211 away from the active adjustment segment 212 moves away from the conveyor belt 300, the active rod 210 rotates so that the active adjustment segment 212 can drive the driven rod 220 to rotate relative to it, so that the end of the driven support segment 221 away from the driven adjustment segment 222 moves away from the conveyor belt 300, decreasing the pressure of the auxiliary pressure roller 230 of the driven support segment 221 on the tobacco pack 400. When there are more than 400 cigarette packs, the friction between the cigarette packs 400 at the rear and the conveyor belt 300 can generate a certain thrust on the conveyor belt 300 at the front to ensure stable and continuous conveying of the cigarette packs 400. When there are too few cigarette packs 400, there may be no cigarette packs 400 under the auxiliary pressure roller 230 located on the drive rod 210. The linkage unit 200 presses down further, which causes the auxiliary pressure roller 230 located on the driven rod 220 to apply more pressure to the small number of cigarette packs 400, further increasing the friction and increasing the thrust on the cigarette packs 400 at the front to complete continuous conveying.
[0038] This conveyor auxiliary pressure device can self-balance the continuously accumulating cigarette packs 400 onto the bottom conveyor belt 300, without causing stress accumulation on the bottom conveyor belt 300, effectively protecting the service life of the conveyor belt 300. In addition, it has a simple structure and is easy to maintain, allowing the cigarette packs 400 to be continuously and uninterruptedly conveyed to the next process.
[0039] In this embodiment, the auxiliary pressure roller 230 is configured as a flexible roller, which further achieves the effect of flexible auxiliary smoke suppression. The flexible roller can be, for example, a roller made of rubber.
[0040] Specifically, the active adjustment section 212 is provided with a slider 2121, and the driven adjustment section 222 is provided with a sliding groove 2221. The slider 2121 is movably inserted into the sliding groove 2221. Under the rotation of the active rod 210, the slider 2121 changes its own position and its relative position with the sliding groove 2221 in the driven adjustment section 222, thereby driving the driven rod 220 to rotate relative to it, so that the driven support section 221 and the active support section 211 have a synchronous movement trend.
[0041] Optionally, to better complete the movement of the linkage unit 200 and improve flexibility, a roller is sleeved on the outer periphery of the slider 2121. The roller is slidably embedded in the sliding groove 2221, reducing the probability of obstruction in the movement of the linkage unit 200. Furthermore, it is stipulated that the slider 2121 and the sliding groove 2221 only undergo relative displacement in a single vertical plane, strengthening the motion correlation between the driven support segment 221 and the active support segment 211, and improving work efficiency. For example, the sliding groove 2221 is set as an elongated circular through groove, and the width of the sliding groove 2221 is limited to fit the outer diameter of the roller. The clearance fit effectively ensures that the limiting member 110 can move linearly within the sliding groove 2221.
[0042] In this embodiment, the active rod 210 further includes an active bending section 213, an active adjusting section 212, an active bending section 213, and an active support section 211 connected in sequence. The active adjusting section 212 and the active support section 211 are set at a preset angle, and the height of the active adjusting section 212 is lower than the mounting base 100. Correspondingly, the driven rod 220 further includes a driven bending section 223, a driven adjusting section 222, a driven bending section 223, and a driven support section 221 connected in sequence. The driven adjusting section 222 and the driven support section 221 are set at a preset angle, and the height of the driven adjusting section 222 is lower than the mounting base 100. Specifically, the active rod 210 and the driven rod 220 can be symmetrically arranged, and the preset angle must be greater than 90°. The active adjusting section 212 and the driven adjusting section overlap, and the linkage structure can adopt an M-type combination follow-up.
[0043] Furthermore, the mounting base 100 is provided with a limiting member 110. The upper surface of the active adjustment section 212 selectively abuts against the limiting member 110. When there is no cigarette pack 400 below the auxiliary pressure roller 230, the auxiliary pressure roller 230 of the linkage unit 200 is given an initial height through the abutment between the active adjustment section 212 and the limiting member 110. For example, the limiting member 110 can be a bolt, which is screwed to the mounting base 100. With the cooperation of a nut, the installation height of the bolt can be selectively set in the vertical direction, which can adjust and limit the maximum clamping force of the conveying auxiliary pressure device on the cigarette pack 400. Both the active rod 210 and the driven rod 220 adopt a three-section bending structure, which can effectively reduce the space height required by the conveying auxiliary pressure device during operation.
[0044] Understandably, in order to facilitate the assembly of the linkage unit 200, it is stipulated that the projections of the active support segment 211 and the driven support segment 221 on the horizontal plane are both located on the same straight line parallel to the extension direction of the mounting base 100; the opposite surfaces of the active adjustment segment 212 and the driven adjustment segment 222 are respectively provided with assembly steps 201, and the step surfaces of the two assembly steps 201 are spaced apart by a preset distance. This setting can ensure the linkage between the active adjustment segment 212 and the driven adjustment segment 222, that is, the relative movement between the limiting member 110 and the limiting groove, while saving the space width required by the conveying auxiliary pressure device during operation.
[0045] For example, the active support leg section 211 and the driven support leg section 221 are rotatably connected to the mounting base 100 by a pin. One end of the pin is provided with an anti-slip protrusion, which can prevent the linkage unit 200 from slipping off the mounting base 100.
[0046] Since the upper surfaces of the cigarette packs 400 arranged together on the conveyor belt 300 are not a complete plane, and the cigarette packs 400 are made of soft material, in order to balance the differences in the upper surfaces of the cigarette packs 400 and to more stably press the auxiliary pressure rollers 230 against the cigarette packs 400, the linkage unit 200 also includes a pressure roller assembly. There are two sets of pressure roller assemblies. One pressure roller assembly plate 240 is rotatably connected to the end of the active support leg section 211 away from the active adjustment section 212 in the vertical plane, and the other pressure roller assembly plate 240 is rotatably connected to the end of the driven support leg section 221 away from the driven adjustment section 222 in the vertical plane. In addition to the auxiliary pressure rollers 230, the pressure roller assembly also includes a pressure roller collection plate 240. Two auxiliary pressure rollers 230 are connected by a wheel axle. The axis of the wheel axle is perpendicular to the conveying direction and is rotatably mounted with the pressure roller collection plate 240. The pressure roller collection plate 240 is equipped with multiple wheel axles at intervals along the conveying direction. That is, one pressure roller collection plate 240 is equipped with twice the number of auxiliary rollers. Multiple auxiliary pressure rollers 230 are symmetrically arranged on both sides of the rotating shaft of the pressure roller collection plate 240.
[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.
