Description

Technical Field

[0001] This utility model relates to the field of tobacco packaging technology, and more specifically, it relates to a conveying and guiding device for a tobacco packaging machine and the packaging machine thereof. Background Technology

[0002] In existing tobacco packaging machines, the pressure plate's holding structure for the packaged goods lacks flexibility in adjustment. This makes it difficult to quickly adapt to packages of different sizes and thicknesses, resulting in cumbersome adjustments and potential scratches from improper fit between the pressure plate and the packaged goods, directly impacting the product's appearance quality.

[0003] Packaging is also prone to deformation during transportation. Due to inertial compression and stress from folding the label paper, packaging often deforms. In severe cases, this can cause it to get stuck in the conveyor channel or downstream station, leading to equipment failure and downtime, and affecting production continuity. Even slight deformation can increase the defect rate of subsequent processes and increase production costs.

[0004] Furthermore, if the packaging and conveyor belt do not fit effectively, the packaging cannot be accurately delivered to the downstream machine station. This can easily cause misalignment between the packaging and the downstream machine station, leading to equipment malfunctions and downtime. Although reducing the conveyor speed can temporarily alleviate the problem, this method will significantly reduce production efficiency.

[0005] Therefore, in order to solve the above-mentioned technical problems, this utility model proposes a tobacco packaging machine conveying and guiding device and the packaging machine thereof. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a conveying and guiding device for a tobacco packaging machine and the packaging machine thereof.

[0007] To achieve the above objectives, in a first aspect, this utility model provides the following technical solution: a conveying and guiding device for a tobacco packaging machine, comprising a track holder, a pressing mechanism, and a connecting rod, wherein the track holder and the pressing mechanism are connected by the connecting rod; The track holder has a track groove for accommodating the pressure plate. The track holder is fastened to the pressure plate through the track groove. The track holder has a plurality of first screw holes, which communicate with the track groove. A first screw is threaded into the first screw hole. The track holder has a first pin hole, in which a pin passes through. The connecting rod has a second pin hole through which the pin passes, and the connecting rod rotates based on the pin. The track holder is provided with a second screw hole, which is connected to the first pin hole. A second screw is threaded into the second screw hole, and the second screw abuts against the surface of the pin. The track holder is provided with a first adjustment mechanism, which is connected to the connecting rod. The first adjustment mechanism applies a spring force to the connecting rod, causing the connecting rod to drive the pressure contact mechanism to apply pressure to the packaging.

[0008] Furthermore, the first adjustment mechanism includes an elastic element and an adjustment bolt. The track holder has a hole for accommodating the elastic element. One end of the elastic element is fixed to the track holder through the hole, and the other end of the elastic element abuts against the adjustment bolt. The other end of the connecting rod has a first threaded hole, which is threadedly connected to the adjustment bolt.

[0009] Furthermore, a first nut is threaded onto the adjusting bolt, and the first nut abuts against the connecting rod.

[0010] Furthermore, the pressure contact mechanism includes a connecting screw, with pressure rollers provided at both ends of the connecting screw, and first bolts threadedly connected to both ends of the connecting screw. The pressure rollers are mounted on the connecting screw via the first bolts, and the pressure rollers can rotate on the connecting screw.

[0011] Furthermore, the pressure contact mechanism is provided with a second adjustment mechanism, which includes an adjustment screw. One end of the connecting rod is provided with a sleeve, and a connecting screw passes through the sleeve. A third screw hole is provided on the sleeve, and the third screw hole is threadedly connected to the adjustment screw. A through hole is provided on the connecting screw for the adjustment screw to pass through.

[0012] Furthermore, the adjusting screw is threadedly connected to a second nut, which abuts against the sleeve.

[0013] Furthermore, the surface of the pressure roller has a V-shaped structure.

[0014] Furthermore, the pressure roller may be selected from bearings, rubber rollers, or nylon rollers as required.

[0015] Furthermore, the elastic element is a spring.

[0016] Secondly, a tobacco packaging machine is provided, including a packaging machine with the aforementioned guiding device internally configured.

[0017] Compared with the prior art, the present invention has the following beneficial effects: In this utility model, the movable design of the track holder and the first and second adjustment mechanisms enable flexible adjustment of the pressure and height of the pressure roller, which can quickly adapt to different specifications of packaging. The adjustment operation is simple, and the V-shaped structure of the pressure roller and the optional materials (bearing, rubber or nylon) can greatly reduce the risk of scratches and indentations on the surface of the packaging, and improve the appearance quality of the product.

[0018] Meanwhile, the controllable pressure of the pressure rollers on the packaging can effectively suppress inertial displacement and the springback of the folded surface of the label paper, ensuring the shaping state of the packaging and the accuracy of the conveying process, reducing equipment failures and downtime caused by deformation or insufficient friction, maintaining production continuity without reducing the conveying speed, thereby improving overall production efficiency and reducing defect rate and production costs.

[0025] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.

[0026] like Figures 1-5 As shown, a tobacco packaging machine is used for packaging tobacco products. During the packaging process, the upstream and downstream conveyor channels 3000 need to convey the packaged items 2000 (such as cigarette boxes or cigarette packs). In the prior art, a pressure plate 3003 is usually used to hold and constrain the conveyed packaged items 2000 to assist in the stable conveying of the packaged items 2000 in the channel. Figure 5 As shown, the conveyor channel 3000 includes a conveyor belt 3001 disposed at the bottom, side plates 3002 disposed on both sides of the conveyor belt 3001, and a pressure plate 3003 disposed opposite to the conveyor belt 3001. The conveyor belt 3001, side plates 3002 and pressure plate 3003 cooperate to form a four-sided limiting mechanism to guide the package 2000.

[0027] However, the existing structure described above has many technical shortcomings in practical applications, as follows: Firstly, the adjustment flexibility is poor. The existing pressure plate 3003 structure is difficult to quickly adapt to packaging materials of different specifications (such as size, thickness, etc.). When adjusting packaging parts 2000 of different specifications, the operation is cumbersome, and scratches are easily caused by improper fit between the pressure plate 3003 and the packaging parts 2000 during the adjustment process, which affects the appearance quality of the product.

[0028] Secondly, package 2000 is prone to deformation. During transportation, package 2000 is easily deformed due to inertial compression and stress from folding the label paper. Severe deformation can cause package 2000 to become stuck in the conveyor channel 3000 or downstream station, directly causing equipment failure and downtime, affecting production continuity. Even slight deformation will increase the defect rate of subsequent processes, negatively impacting product quality and increasing production costs.

[0029] Third, the packaging unit 2000 and the conveyor belt 3001 cannot fit together effectively, and the packaging unit 2000 cannot be accurately transported to the downstream machine station. This can easily cause misalignment between the packaging unit 2000 and the downstream machine station, leading to equipment malfunctions and machine downtime. Although this can be temporarily alleviated by reducing the conveying speed, this method will significantly reduce production efficiency.

[0030] like Figures 1 to 5 As shown, a conveying and guiding device for a tobacco packaging machine and the packaging machine thereof are disclosed. The guiding device includes a track holder 100, a pressing mechanism 200, and a connecting rod 300. The track holder 100 and the pressing mechanism 200 are connected by the connecting rod 300. The track holder 100 has a track groove 101 for accommodating a pressure plate 3003. The track holder 100 can be fastened to the pressure plate 3003 through the track groove 101. In order to fix the track holder 100 to a certain position on the pressure plate 3003, a plurality of first screw holes 103 are provided on the track holder 100, and the first screw holes 103 communicate with the track groove 101. A first screw 102 is threaded into the first screw hole 103. Tightening the first screw 102 causes one end of the first screw 102 to abut against the pressure plate 3003, thereby completing the fixation of the track holder 100. Loosen the first screw 102 so that the first screw 102, which is against the pressure plate 3003, moves away from the pressure plate 3003, thereby releasing the fixation of the track bracket 100. At this time, the track bracket 100 can be moved.

[0031] like Figure 3 As shown, the pressure contact mechanism 200 includes a connecting screw 203, with pressure rollers 201 provided at both ends of the connecting screw 203, and first bolts 202 threadedly connected to both ends of the connecting screw 203. The pressure rollers 201 are mounted on the connecting screw 203 via the first bolts 202, and the pressure rollers 201 can rotate on the connecting screw 203.

[0032] like Figures 1 to 2As shown, a sleeve 302 is provided at one end of the connecting rod 300, and a connecting screw 203 passes through the sleeve 302. A first pin hole 104 is provided on the track holder 100, and a pin 600 passes through the first pin hole 104. A second pin hole 303 is provided on the connecting rod 300 for the pin 600 to pass through, and the connecting rod 300 can rotate based on the pin 600. With the swing of the connecting rod 300, the pressure contact mechanism 200 can be adjusted based on the track holder 100. By controlling the pin 600 to be inserted into the first pin hole 104 and the second pin hole 303, or to be pulled out of the first pin hole 104 and the second pin hole 303, the limit of the connection can be controlled.

[0033] To prevent the pin 600 from falling out during operation, a second screw hole 105 is provided on the track holder 100. The second screw hole 105 connects to the first pin hole 104, and a second screw 601 is threaded into the second screw hole 105. By tightening the second screw 601, the second screw 601 abuts against the surface of the pin 600, thereby fixing the pin 600. Conversely, by loosening the second screw 601, the pin 600 can be removed.

[0034] A first adjusting mechanism 400 is provided on the track holder 100. The first adjusting mechanism 400 is connected to the connecting rod 300. The first adjusting mechanism 400 can apply different elastic forces to the connecting rod 300, so that the connecting rod 300, in cooperation with the pin 600, provides a certain pressure to the pressing mechanism 200. The first adjusting mechanism 400 includes an elastic element 401 and an adjusting bolt 402. The elastic element 401 can be a spring or other elastic material. One end of the elastic element 401 is fixed to the track holder 100, and the other end of the elastic element 401 abuts against the adjusting bolt 402. Please refer to [link to relevant documentation]. Figure 2 The adjusting bolt 402 has a protrusion at one end corresponding to the elastic element 401, and the adjusting bolt 402 can be engaged with the elastic element 401 through the protrusion. The other end of the connecting rod 300 has a first threaded hole 301, which is threadedly connected to the adjusting bolt 402. The elastic element 401 can be a spring.

[0035] like Figure 2As shown, by rotating the adjusting bolt 402, the adjusting bolt 402 moves axially based on the connecting rod 300. When the adjusting bolt 402 is rotated forward, it moves towards the track holder 100 based on the connecting rod 300. At this time, the adjusting bolt 402 compresses the elastic element 401, so the elastic element exerts an upward elastic force on the connecting rod 300 away from the track holder 100 through the adjusting bolt 402. Since the connecting rod 300 is limited by the pin 600 and rotatably mounted on the track holder 100, under the action of the lever principle, the other end of the connecting rod 300 exerts a downward pressure on the pressure contact mechanism 200, thereby pressing the pressure roller 201 against the surface of the package 2000, applying pressure to it and making it adhere to the conveyor belt. Furthermore, by rotating the adjusting bolt 402, the pressure exerted on the package 2000 by the pressure roller 201 can be adjusted, providing high flexibility and ease of adjustment. By using different elastic elements, the first adjustment mechanism 400 can achieve pressure adjustment from 5 to 10 N.

[0036] It is worth noting that, in order to prevent the threaded connection between the adjusting bolt 402 and the first threaded hole 301 from loosening and affecting the elastic force applied to the pressure contact mechanism 200, a first nut 403 is also threadedly connected to the adjusting bolt 402. The first thread abuts against the connecting rod 300 to limit the connecting rod 300.

[0037] Based on the above, the pressure contact mechanism 200 is further provided with a second adjustment mechanism 500. The second adjustment mechanism 500 includes an adjustment screw 502. A third threaded hole 700 is provided on the sleeve 302 for the adjustment bolt 402 to pass through. The third threaded hole 700 is threadedly connected to the adjustment bolt 402. A through hole 701 is provided on the connecting screw 203 for the adjustment screw 502 to pass through. When the adjustment screw 502 rotates, since the adjustment bolt 402 is threadedly connected to the third threaded hole 700, the connecting screw 203 will extend out when the adjustment bolt 402 rotates in the forward direction. Figure 5 As shown, the adjusting bolt 402 abuts against the pressure plate 3003, causing the end of the connecting rod 300 with the sleeve 302 to move away from the pressure plate 3003. Under the action of the lever principle, the connecting rod 300 further compresses the elastic element 401. This allows the pressure roller 201 to be adjusted horizontally based on the pressure plate 3003, achieving a second adjustment of the pressure roller 201, i.e., fine-tuning, a further adjustment of the first adjustment, improving adaptability and flexibility. This allows the compaction mechanism 1000 to adjust the pressure of the pressure roller 201 on the package 2000 according to different situations. While limiting the package 2000, it also allows the package 2000 to adhere to the conveyor belt 3001, thereby increasing the friction between the package 2000 and the conveyor belt 3001 and preventing the situation where the surface of the package 2000 is made of a smooth material, making it difficult for the conveyor belt 3001 to drive the package 2000 to move.

[0038] It should be noted that a second nut 501 is threaded onto the adjusting screw 502. The second nut 501 abuts against the surface of the connecting screw 203 to prevent the threaded connection between the adjusting screw 502 and the third screw hole 700 from loosening.

[0039] Furthermore, the surface of the pressure roller 201 can be designed with a 60-degree V-shaped structure, allowing the pressure roller 201 to form double-line contact with the label paper, achieving optimal contact posture. In addition, the structure of the pressure roller 201 is easy to disassemble, and the appropriate material for the pressure roller 201 can be selected according to the printing process of the label paper. Bearings, rubber rollers, or nylon rollers can be selected. If the label paper surface has embossed printing, the rubber roller can adapt well to slight variations in paper thickness, and the V-groove double-line contact provides a "soft contact," greatly reducing the risk of scratches and indentations.

[0040] In summary, this application, through the compaction mechanism 1000 in the conveying channel 3000, forms a controllable pressure contact of 5 to 10 N on the surface of the small box. This effectively suppresses the inertial displacement and springback of the folded surface of the small box during conveying, ensuring that the label paper maintains its shaping pressure and centering state continuously during conveying. This reduces packaging deformation or centering failures caused by the label paper, lowers the frequency of equipment downtime, and enables the packaging machine to operate continuously and stably, thereby improving overall production efficiency. Simultaneously, by reducing the risk of scratches and indentations on the label paper surface, it effectively reduces the generation of defective packaging products, which is also beneficial for product cost control and indirectly improves production efficiency.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
