Description

Technical Field

[0001] This utility model relates to the technical field of tobacco processing equipment, and in particular to a multi-station cutting machine for polylactic acid fiber filter cartridges for tobacco. Background Technology

[0002] Polylactic acid (PLA) fiber filter cartridges for cigarettes are a new type of environmentally friendly cigarette filter material made of polylactic acid, a biodegradable thermoplastic polyester synthesized from starch extracted from renewable plant resources through fermentation, polymerization, and other processes. This type of filter cartridge not only possesses similar filtration performance to traditional cellulose acetate filter cartridges, effectively trapping harmful substances such as tar and nicotine in cigarette smoke, but also exhibits excellent biocompatibility and biodegradability. After use, it decomposes in the natural environment, significantly reducing environmental pollution and aligning with the current trend of green and environmentally friendly development. Therefore, it is increasingly widely used in the tobacco industry.

[0003] In the production process of polylactic acid fiber filter cartridges for cigarettes, the continuously produced long strip filter cartridge materials need to be cut into independent filter cartridge units that meet the assembly requirements of cigarettes. The cutting machine is a special equipment used to achieve this cutting function. It uses mechanical transmission and cutting tools to precisely cut the continuous filter cartridge materials. It is an indispensable key equipment on the production line of polylactic acid fiber filter cartridges for cigarettes.

[0004] In the prior art, such as Chinese Patent Publication No. CN223000696U, a filter element cutting device is disclosed. It includes a cutting component for cutting the filter element; a pushing component disposed on one side of the cutting component for pushing the filter element; a clamping component disposed on the bottom surfaces of the cutting component and the pushing component for clamping and limiting the filter element; and a touch screen all-in-one machine disposed on one side surface of the cutting component. The clamping component includes a worktable with pneumatic linear slides on both sides of the center of the top surface of the worktable. This invention can automatically cut filter elements of different thicknesses and facilitate the replacement of the push plate, thereby enabling convenient pushing of filter elements of different thicknesses and improving convenience.

[0005] Although the cutting component, pushing component, clamping component, and touch screen all-in-one machine in the aforementioned patent can automatically cut filter elements of different thicknesses and facilitate the replacement of push plates, there are still obvious shortcomings. The device can only cut a single filter element at a time, and the frequent single operations lead to low processing efficiency when facing large-scale production needs. Furthermore, during the filter element pushing process, there is a lack of a precise control structure for the pushing length. Relying on conventional pushing methods, it is difficult to ensure that the length of the filter element extending each time is consistent, resulting in a large deviation in the size of the cut filter elements, which cannot meet the requirements of high-precision production. Utility Model Content

[0006] This invention proposes a multi-station cutting machine for polylactic acid fiber filter cartridges for tobacco. Through multi-station synchronous cutting and precise positioning structure design, it improves the processing efficiency and cutting accuracy of filter cartridges, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a multi-station cutting machine for polylactic acid fiber filter cartridges for cigarettes, including a cutting workbench, a multi-station pusher fixedly installed on the top rear side of the cutting workbench, and a cutting component provided on the front upper side of the multi-station pusher.

[0008] The multi-station pusher includes a connecting baffle, which is fixedly connected to the top of the cutting workbench. The top of the connecting baffle has four arc-shaped grooves, and the inner surface of the arc-shaped grooves is rotatably connected to two rolling support blocks. The rear side of the connecting baffle is fixedly connected to four connecting sleeves, and the inner surface of the connecting sleeves is slidably connected to a sliding push plate. The top left and right sides of the sliding push plate are slidably inserted with guide posts, and the top ends of two guide posts are fixedly connected to a lifting slide plate. The front sides of the lifting slide plate and the sliding push plate are both fixedly connected to two clamping posts.

[0009] Preferably, a first motor is fixedly connected to the rear end of the connecting sleeve plate, the output shaft of the first motor passes through the interior of the connecting sleeve plate and is fixedly connected to a first screw, the outer surface of the first screw is threadedly connected to the bottom center of the sliding push plate, a knob is rotatably connected to the top center of the lifting slide plate, the bottom end of the knob passes through the bottom of the lifting slide plate and is fixedly connected to a second screw, the outer surface of the second screw is threadedly connected to the top center of the sliding push plate.

[0010] Preferably, the cutting assembly includes two support plates, which are fixedly connected to the left and right sides of the cutting workbench, respectively. Two sliding guide rods are fixedly connected to the top of the opposite surfaces of the two support plates. A connecting slide plate is slidably connected to the outer surface of the two sliding guide rods. A third motor is fixedly connected to the top of the left surface of the left support plate. The output shaft of the third motor passes through to the right surface of the left support plate and is fixedly connected to a third screw. The outer surface of the third screw is threadedly connected to the middle of the connecting slide plate.

[0011] Preferably, a cutting machine housing is fixedly connected to the bottom of the connecting slide plate, and a second motor is fixedly connected to the front side of the cutting machine housing. The output shaft of the second motor passes through the inner side of the cutting machine housing and is fixedly connected to a cutting blade.

[0012] Preferably, a material drop chute is provided on the lower front side of the multi-station pusher, the material drop chute is opened at the top center of the cutting workbench, a collection box is slidably engaged at the bottom center of the cutting workbench, and the bottom end of the material drop chute extends through to the top of the collection box.

[0013] Preferably, the cutting workbench has four limiting slide grooves on the top front side, the rear end of the limiting slide groove extends to the front surface of the inner wall of the material drop chute, the inner surface of the limiting slide groove is slidably connected to a limiting slide plate, the top rear side of the limiting slide plate is fixedly connected to a limiting baffle, the top front side of the limiting slide plate is threaded with a fastening bolt, and the bottom end of the fastening bolt extends to the lower surface of the limiting slide groove.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. In this utility model, the multi-station pusher consists of four independent sliding push plates and matching lifting slide plates and clamping columns. Each sliding push plate and its components can independently clamp and push one filter element. During operation, the first motor drives the four first screws to rotate, causing the four sliding push plates to move horizontally synchronously, extending the four filter elements from the connecting baffle at the same time. In conjunction with the third motor in the cutting assembly, the third screw drives the connecting slide plate to slide left and right, so that the cutting blade can cut the four filter elements synchronously. Compared with the prior art, which can only cut a single filter element at a time, this structure greatly improves the processing efficiency of polylactic acid fiber filter elements for tobacco through the cooperation of multiple independent pushing and clamping units and sliding cutting blades, meeting the needs of large-scale production.

[0016] 2. In this utility model, after the filter element is pushed out by the multi-station pusher, it will abut against the limiting baffle to fix the amount of filter element extension. The limiting slide can slide in the limiting groove set on the front side of the top of the cutting table, thereby adjusting the position of the limiting baffle. After adjustment, the fastening bolt is screwed through the limiting slide into the limiting groove to fix the position of the limiting slide and the limiting baffle. Compared with the problem of difficult control of filter element pushing length in the prior art, this structure can accurately control the amount of filter element extension, ensure that the filter element length is consistent in each cutting, significantly improve the accuracy of filter element cutting and improve product quality.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 As shown, this utility model provides a technical solution: including a cutting workbench 1, a multi-station pusher 2 fixedly installed on the top rear side of the cutting workbench 1, a cutting component 3 provided on the front upper side of the multi-station pusher 2, a material drop chute 4 provided on the front lower side of the multi-station pusher 2, the material drop chute 4 being opened at the top center of the cutting workbench 1, a collection box 5 being slidably engaged at the bottom center of the cutting workbench 1, the bottom end of the material drop chute 4 penetrating to the top of the collection box 5, four limiting slide grooves 6 being opened on the top front side of the cutting workbench 1, the rear end of the limiting slide groove 6 penetrating to the front surface of the inner wall of the material drop chute 4, a limiting slide plate 7 being slidably connected to the inner surface of the limiting slide groove 6, a limiting baffle 8 being fixedly connected to the top rear side of the limiting slide plate 7, a fastening bolt 9 being threadedly connected to the top front side of the limiting slide plate 7, and the bottom end of the fastening bolt 9 penetrating to the lower surface of the limiting slide groove 6;

[0025] The overall effect of Embodiment 1 is as follows: the material drop chute 4 and the collection box 5 constitute the collection channel after the filter element is cut. When the filter element is cut by the cutting component 3, it will slide down the material drop chute 4 into the collection box 5 under the action of gravity, realizing the automatic collection of the cut filter element, which is convenient for subsequent sorting and transportation. The limiting slide 6, the limiting slide plate 7 and the fastening bolt 9 constitute the precise adjustment and positioning structure for the extension length of the filter element. By loosening the fastening bolt 9, the limiting slide plate 7 can be pushed to slide back and forth in the limiting slide chute 6, thereby adjusting the position of the limiting baffle 8. After setting the extension length of the filter element, tightening the fastening bolt 9 can fix the limiting slide plate 7 and the limiting baffle 8, providing a reliable positioning reference for the precise cutting of the filter element.

[0026] Example 2: As Figure 2 and Figure 3 As shown, this utility model provides a technical solution: a multi-station pusher 2 includes a connecting baffle 21, which is fixedly connected to the top of the cutting workbench 1. The top of the connecting baffle 21 has four arc-shaped grooves 22. Two rolling support blocks 23 are rotatably connected to the inner surface of each arc-shaped groove 22. Four connecting sleeves 24 are fixedly connected to the rear side of the connecting baffle 21. Sliding push plates 25 are slidably connected to the inner surface of each connecting sleeve 24. Guide posts 26 are slidably inserted into the left and right sides of the top of each sliding push plate 25. A lifting slide plate 27 is fixedly connected to the top of each of the two guide posts 26. Two clamping posts 28 are fixedly connected to the front sides of both plate 27 and sliding push plate 25. A first motor 29 is fixedly connected to the rear end of connecting sleeve plate 24. The output shaft of the first motor 29 passes through the interior of connecting sleeve plate 24 and is fixedly connected to a first screw 210. The outer surface of the first screw 210 is threadedly connected to the bottom center of the sliding push plate 25. A knob 211 is rotatably connected to the top center of lifting slide plate 27. The bottom end of the knob 211 passes through the bottom of lifting slide plate 27 and is fixedly connected to a second screw 212. The outer surface of the second screw 212 is threadedly connected to the top center of the sliding push plate 25.

[0027] The overall effect achieved by Embodiment 2 is as follows: the four connecting sleeves 24, the sliding push plate 25, the guide post 26, the lifting slide plate 27, and the clamping post 28 constitute four independent filter element pushing and clamping units. During operation, the first motor 29 starts, and its output shaft drives the first screw 210 to rotate. Under the action of threaded transmission, the sliding push plate 25 can move back and forth horizontally within the connecting sleeves 24, thereby pushing the filter element on the clamping post 28 forward. At the same time, when dealing with filter elements of different diameters, the second screw can be driven by rotating the knob 211. When screw 212 rotates, the second screw 212 engages with the sliding push plate 25, causing the lifting slide plate 27 to move up and down along the guide post 26, thereby adjusting the height of the clamping post 28. This ensures that the four clamping posts 28 can fit tightly against the surface of the filter element, achieving stable clamping of filter elements of different specifications. The arc groove 22 and the rolling support block 23 on the connecting baffle 21 play an auxiliary support and guiding role during the filter element pushing process. The rolling support block 23 can rotate within the arc groove 22, reducing friction between the filter element and the connecting baffle 21 and ensuring smooth filter element pushing.

[0028] Example 3: As Figure 4 As shown, this utility model provides a technical solution: the cutting component 3 includes two support plates 31, which are fixedly connected to the left and right sides of the cutting workbench 1 respectively. Two sliding guide rods 32 are fixedly connected to the top of the opposite surfaces of the two support plates 31. A connecting slide plate 33 is slidably connected to the outer surface of the two sliding guide rods 32. A third motor 37 is fixedly connected to the top of the left surface of the left support plate 31. The output shaft of the third motor 37 passes through to the right surface of the left support plate 31 and is fixedly connected to a third screw 38. The outer surface of the third screw 38 is threadedly connected to the middle of the connecting slide plate 33. A cutting machine housing 34 is fixedly connected to the bottom of the connecting slide plate 33. A second motor 35 is fixedly connected to the front side of the cutting machine housing 34. The output shaft of the second motor 35 passes through to the inner side of the cutting machine housing 34 and is fixedly connected to a cutting blade 36.

[0029] The overall effect achieved in Embodiment 3 is as follows: The third motor 37, the third screw 38, the sliding guide rod 32, and the connecting plate 33 form a horizontal movement drive mechanism for the cutting blade 36. After the third motor 37 is started, it drives the third screw 38 to rotate. The connecting plate 33 is threadedly connected to the third screw 38 and can slide left and right along the sliding guide rod 32 under the guidance of the sliding guide rod 32, thereby driving the cutting machine housing 34 and the cutting blade 36 to move synchronously. The second motor 35 is connected to the cutting blade 36. After the second motor 35 is started, its output shaft drives the cutting blade 36 to rotate at high speed. When the connecting plate 33 drives the cutting blade 36 to move to a suitable position, the cutting blade 36 can cut the filter element pushed by the multi-station pusher 2. Through the coordinated work of the third motor 37 and the second motor 35, the precise horizontal movement and high-speed cutting action of the cutting blade 36 are achieved, meeting the requirement of synchronous cutting of multiple filter elements.

[0030] The working principle of the entire equipment is as follows: First, according to the diameter of the filter element to be cut, the height of the lifting slide plate 27 is adjusted by rotating the knob 211 so that the four sets of clamping columns 28 can be adapted to filter elements of different specifications. The long strip of filter element material is placed between the four sets of clamping columns 28 in sequence, and the filter element is clamped and fixed by the clamping columns 28. Next, the first motor 29 is started, and the four first motors 29 operate synchronously, driving the four first screws 210 to rotate, which drives the four sets of sliding push plates 25 to move forward, pushing the filter element forward from the connecting baffle 21. When the front end of the filter element abuts against the limiting baffle 8, it stops. At this time, the extension length of the filter element is the set cutting length. Then, the third motor 37 is started, driving the third screw 38 to rotate, causing the connecting slide plate 33 to move along the sliding guide rod 32, moving the cutting blade 36 to the corresponding position above the filter element. At the same time, the second motor 35 is started, causing the cutting blade 36 to rotate at high speed. Finally, the third motor 37 continues to drive the connecting slide plate 33 to move, causing the cutting blade 36 to move laterally, cutting the four filter elements simultaneously. The cut filter elements fall into the collection box 5 along the material drop chute 4 under the action of gravity. After one cut is completed, the first motor 29 rotates again to continuously push the filter elements again. The above operation is repeated to achieve continuous multi-station efficient and precise cutting of polylactic acid fiber filter elements for tobacco.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
