Description

Technical Field

[0001] This utility model relates to the technical field of tobacco processing equipment, and more specifically, to an adjustable protective tobacco clamping device. Background Technology

[0002] In tobacco processing, the tobacco-binding operation is a crucial step. Traditional methods, such as using tobacco sticks to bind the tobacco, have many drawbacks. Binding is extremely slow, typically requiring two people: one to organize and pass the tobacco leaves, and the other to bind them—a time-consuming and labor-intensive process. Furthermore, binding is inefficient, accounting for more than a quarter of the labor required in the curing process. In addition, removing the tobacco from the sticks after curing is also fraught with difficulties. For example, the intelligent tobacco binding machine based on machine vision disclosed in Chinese Patent CN217017524U, while possessing some automatic recognition and binding functions, still suffers from slow binding efficiency and complex operating procedures. Tobacco farmers must promptly replace substandard tobacco leaves before proceeding to the next step, significantly reducing overall binding efficiency and increasing the labor intensity for farmers.

[0003] For example, the tobacco leaf clamping rack with patent publication number CN218337698U, while capable of stacking fresh tobacco leaves in multiple layers and increasing the space for hot air flow, requires multiple placements of dividers and layered laying of tobacco leaves, resulting in high labor costs, long processing times, and significant inconvenience. Comb-type tobacco clamps, while improving clamping efficiency to some extent, have a relatively complex structure and high cost. Furthermore, with increased use, the clamping force of comb-type tobacco clamps may decrease, causing tobacco leaves to easily fall off during the roasting process, affecting roasting quality. Similarly, some tobacco clamps using spring force to hold tobacco leaves also suffer from reduced spring clamping force with repeated use, eventually becoming unable to hold the tobacco leaves, severely impacting the roasting effect and production efficiency. Therefore, the development of an efficient, convenient, stable, and cost-effective adjustable protective tobacco leaf clamping device is urgently needed to meet the needs of modern tobacco processing and production, and improve the overall efficiency of tobacco production. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable protective tobacco leaf clamping device to solve the problem mentioned in the background art that the clamping force of the comb-type tobacco clamp may decrease, causing the tobacco leaves to easily fall off during the baking process and affecting the baking quality.

[0005] To achieve the above objectives, this utility model provides an adjustable protective tobacco clamping device, including an operating table. An adjustable clamping component is installed on the top of the operating table. The adjustable clamping component includes a frame, and a plurality of movable clamping rods are arranged on the inner side of the frame. Adjacent movable clamping rods are connected by telescopic connectors. One end of the movable clamping rod is connected to a fixed rod through the telescopic connector, and the other end of the movable clamping rod is driven to move linearly by an adjustment component, thereby driving each movable clamping rod to move synchronously and realize the spacing adjustment.

[0006] This setup involves installing an adjustable clamping component on the top of the control panel, connecting several movable clamping rods to a fixed rod using a telescopic connector, and then using an adjustment component to drive one movable clamping rod to move, causing all movable clamping rods to move synchronously to adjust the spacing.

[0007] Preferably, the upper and lower ends of the fixing rod are fixedly connected to the frame.

[0008] This feature securely connects the upper and lower ends of the fixing rod to the frame, making the fixing rod the reference support for the entire adjustable clamping component.

[0009] Preferably, a track groove is installed on the inner wall of the frame near the end of the movable clamping rod, and the end of the movable clamping rod slides into the track groove.

[0010] This feature involves installing a track groove on the inner wall of the frame, allowing the end of the movable clamping rod to slide in the track groove, thereby restricting and guiding the movement direction of the movable clamping rod.

[0011] Preferably, the telescopic connector is an X-shaped structure composed of two rods, which are rotatably connected by a first connecting shaft, and the ends of adjacent telescopic connectors are rotatably connected by a second connecting shaft.

[0012] This telescopic connector uses an X-shaped structure composed of two rods. The two rods are rotatably connected by a first connecting shaft, and the ends of adjacent telescopic connectors are rotatably connected by a second connecting shaft, forming a telescopic linkage structure.

[0013] Preferably, the second connecting shaft at one end of the telescopic connector is fixed to the movable clamping rod, and the second connecting shaft at the other end of the telescopic connector slides into a groove on the movable clamping rod.

[0014] This feature involves fixing the second connecting shaft at one end of the telescopic connector to the movable clamping rod, while the second connecting shaft at the other end slides into a groove on the movable clamping rod. This design ensures that the telescopic connector has both a fixed transmission point and a sliding adjustment point when it moves the movable clamping rod.

[0015] Preferably, the surface of the movable clamping rod is fitted with a protective pad.

[0016] This feature involves installing a protective pad on the surface of the movable clamping rod, utilizing the flexibility and cushioning of the pad to contact the tobacco leaves.

[0017] Preferably, the adjusting assembly includes a housing, inside which a lead screw is installed, and a lead screw slider is mounted on the lead screw. The lead screw slider is connected to the movable clamping rod at the end away from the fixed rod.

[0018] This setting adjustment component uses a lead screw and lead screw slider inside the housing. When the lead screw is rotated, the lead screw slider moves linearly along the lead screw, thereby driving the movable clamp rod connected to it to move.

[0019] Preferably, a handle is installed at one end of the lead screw.

[0020] This feature involves installing a handle at one end of the lead screw. Rotating the handle causes the lead screw to rotate, thereby driving the lead screw slider and movable clamp to move.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: In this adjustable protective tobacco clamping device, the screw and slider mechanism of the adjustment component allows for linear movement of the end clamping rods simply by turning the handle. The X-shaped telescopic connector then synchronizes the spacing of all the clamping rods. Compared to the traditional two-person collaborative method of tobacco weaving or the cumbersome operation of repeatedly placing dividers, a single person can quickly adjust the clamping spacing, significantly reducing labor requirements and shortening preparation time. The movable clamping rods are precisely guided by the track grooves, and the rigid transmission of the telescopic connector ensures that the clamping rods maintain good parallelism when the spacing is adjusted, avoiding the clamping deviation problem caused by the loose structure of traditional comb-type cigarette clamps. At the same time, the self-locking characteristic of the screw drive can stably maintain the clamping force, solving the defect of the clamping force decay of spring-type cigarette clamps after long-term use, and effectively reducing the shedding of tobacco leaves throughout the entire curing process.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides an adjustable protective tobacco leaf clamping device, such as Figure 1 , Figure 2 As shown, the device includes an operating table 1. An adjustable clamping component 2 is installed on the top of the operating table 1. The adjustable clamping component 2 includes a frame 21. Several movable clamping rods 22 are arranged on the inner side of the frame 21. Adjacent movable clamping rods 22 are connected by telescopic connectors 24. One end of the movable clamping rod 22 is connected to a fixed rod 23 through the telescopic connector 24. The other end of the movable clamping rod 22 is driven to move linearly by an adjustment component 25, thereby driving each movable clamping rod 22 to move synchronously and realize the spacing adjustment.

[0025] By installing an adjustable clamping component 2 on the top of the operating table 1, several movable clamping rods 22 are connected to a fixed rod 23 via a telescopic connector 24. An adjusting component 25 then drives one movable clamping rod 22 to move, causing all movable clamping rods 22 to move synchronously to adjust the spacing. The effect is that it enables flexible adjustment of the spacing between the movable clamping rods 22, adapting to the clamping needs of different quantities and specifications of tobacco leaves. This overcomes the limitations of fixed spacing in traditional tobacco clamping devices, improving the versatility and operational flexibility of the device.

[0026] In this embodiment, as Figure 1 , Figure 2 As shown, the upper and lower ends of the fixing rod 23 are fixedly connected to the frame 21.

[0027] The upper and lower ends of the fixed rod 23 are fixedly connected to the frame 21, making the fixed rod 23 the reference support for the entire adjustable clamping component 2. This provides a stable reference base for the movement of the movable clamping rod 22, ensuring the overall structural stability of the movable clamping rod 22 during adjustment and avoiding clamping offset problems caused by loosening of the fixed rod 23.

[0028] Specifically, such as Figure 1, Figure 2 As shown, a track groove 26 is installed on the inner wall of the frame 21 near the end of the movable clamp 22, and the end of the movable clamp 22 slides in conjunction with the track groove 26.

[0029] A track groove 26 is installed on the inner wall of the frame 21, allowing the end of the movable clamping rod 22 to slide in the track groove 26, thus restricting and guiding the movement direction of the movable clamping rod 22. This ensures that the movable clamping rod 22 can only move in a straight line along the track groove 26, preventing skewness or offset during movement, guaranteeing parallelism between the movable clamping rods 22, and improving clamping accuracy.

[0030] Furthermore, such as Figure 3 As shown, the telescopic connector 24 is an X-shaped structure composed of two rods. The two rods are rotatably connected by a first connecting shaft 241, and the ends of adjacent telescopic connectors 24 are rotatably connected by a second connecting shaft 242.

[0031] The telescopic connector 24 adopts an X-shaped structure composed of two rods. The two rods are rotatably connected by a first connecting shaft 241, and the ends of adjacent telescopic connectors 24 are rotatably connected by a second connecting shaft 242, forming a telescopic linkage structure. The effect is that when one movable clamping rod 22 moves, the telescopic connector 24 can drive all movable clamping rods 22 to move synchronously and evenly, ensuring the consistency of spacing adjustment.

[0032] Furthermore, such as Figure 3 As shown, the second connecting shaft 242 at one end of the telescopic connector 24 is fixed on the movable clamping rod 22, and the second connecting shaft 242 at the other end of the telescopic connector 24 slides in cooperation with the sliding groove 221 opened on the movable clamping rod 22.

[0033] The second connecting shaft 242 at one end of the telescopic connector 24 is fixed to the movable clamping rod 22, and the second connecting shaft 242 at the other end slides into the sliding groove 221 on the movable clamping rod 22. This allows the telescopic connector 24 to have both a fixed transmission point and a sliding adjustment point when moving the movable clamping rod 22. The effect is to further optimize the linkage between the movable clamping rods 22, ensuring smoother and more coordinated movement of each movable clamping rod 22 during spacing adjustment, avoiding jamming or uneven force distribution.

[0034] Furthermore, such as Figure 3 As shown, a protective pad 223 is installed on the surface of the movable clamp 22.

[0035] A protective pad 223 is installed on the surface of the movable clamp 22, utilizing the flexibility and cushioning of the protective pad 223 to contact the tobacco leaves. This effectively prevents the movable clamp 22 from causing compression damage to the tobacco leaves, reducing the breakage rate during clamping. Simultaneously, it increases the friction between the clamp and the tobacco leaves, improving clamping stability and ensuring the quality of the tobacco leaves.

[0036] Furthermore, such as Figure 4 As shown, the adjustment assembly 25 includes a housing 251, a lead screw 252 is installed inside the housing 251, a lead screw slider 253 is installed on the lead screw 252, and the lead screw slider 253 is connected to a movable clamping rod 22 at the end away from the fixed rod 23.

[0037] The adjusting component 25 engages with a lead screw 252 and a lead screw slider 253 within the housing 251. When the lead screw 252 is rotated, the lead screw slider 253 moves linearly along the lead screw 252, thereby driving the connected movable clamping rod 22 to move. This achieves precise control over the movement of the movable clamping rod 22. Through the transmission characteristics of the lead screw 252, the spacing of the movable clamping rod 22 can be precisely adjusted. Furthermore, the lead screw 252 transmission has a self-locking function, ensuring the adjusted spacing remains stable and preventing changes in spacing due to external forces.

[0038] Furthermore, such as Figure 4 As shown, a handle 254 is installed at one end of the lead screw 252.

[0039] A handle 254 is installed at one end of the lead screw 252. Rotating the handle 254 causes the lead screw 252 to rotate, thereby driving the lead screw slider 253 and the movable clamping rod 22 to move. This provides operators with convenient operating components, making adjustment operations more effortless and convenient, reducing operational difficulty, and improving work efficiency.

[0040] In use, the adjustable protective tobacco clamping device of this utility model initially maintains a distance between the movable clamping rod 22 and the fixed rod 23. All movable clamping rods 22 are interconnected via telescopic connectors 24, and their ends are embedded in the track grooves 26 of the frame 21. The operator can determine the required clamping rod spacing based on the quantity, thickness, and other specifications of the tobacco leaves to be clamped. The operator rotates the handle 254 of the adjusting assembly 25, causing the lead screw 252 to rotate within the housing 251. Because the lead screw slider 253 is threadedly engaged with the lead screw 252, the rotational motion of the lead screw 252 is converted into linear motion of the lead screw slider 253, which in turn pushes the connected end movable clamp 22 to move. When the movable clamping rod 22 at the end moves along the track groove 26, the adjacent movable clamping rods 22 move synchronously through the linkage of the X-shaped telescopic connector 24: the two rods of the telescopic connector 24 rotate around the first connecting shaft 241, while the second connecting shaft 242 slides in the slide groove 221 of the movable clamping rod 22, so that all movable clamping rods 22 change their spacing evenly until the required size is reached. Due to the self-locking characteristic of the screw drive, the adjusted spacing can be stably maintained. The prepared tobacco leaves are placed between the movable clamping rods 22. The protective pads 223 on the surface of the movable clamping rods 22 prevent damage to the tobacco leaves through flexible contact, while increasing friction to prevent the tobacco leaves from slipping. The rigid connection between the fixed rod 23 and the frame 21 provides stable support for the entire clamping structure, and the track groove 26 ensures that the movable clamping rods 22 do not tilt, ensuring the neatness of the tobacco leaves being clamped. After clamping, the entire device can be moved to the baking or processing area. After the operation is completed, turn the handle 254 in the opposite direction. The cooperation between the lead screw 252 and the lead screw slider 253 will drive the movable clamping rod 22 to reset, and the telescopic connecting piece 24 will retract synchronously, so that the device returns to its initial state for the next use.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
