Description

Technical Field

[0001] The utility model relates to an impurity removal device, in particular to a tobacco leaf vibration impurity removal device. Background Art

[0002] Tobacco processing is a complex, multi-step process, from leaf picking, drying, and fermentation to final cutting and rolling. Each step directly impacts the quality and market competitiveness of the final product. Removing impurities (including leaf fragments, weeds, insects, and dust) is a critical step in tobacco processing, effectively improving leaf quality. Currently, impurity removal methods primarily focus on manual and mechanical methods. Traditionally, this process relies on manual labor, which is time-consuming, labor-intensive, and susceptible to human error.

[0003] Mechanical impurity removal is generally electrostatic impurity removal, air separation impurity removal, vibration impurity removal, or a combination of vibration impurity removal, electrostatic impurity removal, and air separation impurity removal. For example, the patent application with the announcement number CN115971050A discloses a method for removing broken tobacco flakes after wind impurity removal. The method comprises the following steps: after wind impurity removal and air separation, the broken tobacco flakes and light debris are passed through a three-layer vibrating screening machine. The upper layer screens the large tobacco flakes and then returns them to the main production line. The lower layer screens and collects the discarded crushed powder and sand. The middle layer screens the main material of the broken tobacco flakes and then enters a hemp silk removal machine. The hemp silk removal machine adheres to and removes the long cotton threads, hemp ropes, plastic threads and hemp silk in the broken tobacco flakes. The material is then lifted to the required drop height by a steep-angle belt conveyor, the production process channel is selected by a flap regulating valve, and it is manually switched whether to enter an electrostatic impurity remover to utilize the electrostatic adsorption effect to suck out the remaining light debris, mainly weeds and hemp silk, in the broken tobacco flakes. Finally, the broken tobacco flakes are returned to the main production line for a second beating through wind conveying, thereby achieving comprehensive and thorough removal of all kinds of debris in the broken tobacco flakes. This application improves the efficiency of debris removal and the purity and utilization rate of tobacco raw materials; reduces production and operation costs; and alleviates the difficulty of production management.

[0004] While the aforementioned impurity removal method is effective, it also requires two workers to sort out any remaining debris before pneumatic conveying returns it to the main production line for a second round. Manually sorting out debris requires intense focus, which can easily lead to visual fatigue and, due to human limitations, can easily lead to omissions. Therefore, it is necessary to design a tobacco leaf vibration impurity removal device to address this issue. Summary of the Invention

[0005] The purpose of the utility model is to provide a tobacco leaf vibration impurity removal device which is not easy to cause omissions, can effectively remove impurities and can eliminate visual fatigue.

[0006] The technical solution of the utility model is:

[0007] A tobacco leaf vibration impurity removal device consists of an assembly seat, a spring sleeve, a tobacco leaf clamping mechanism, a spring, a crankshaft, a crank and a connector, and is characterized in that: the assembly seat is a rectangular body, and the four corners of the bottom of the assembly seat are respectively provided with spring sleeves; a tobacco leaf clamping mechanism for clamping tobacco leaves is provided below the assembly seat, and the tobacco leaf clamping mechanism is connected to the spring sleeve through a spring; a crankshaft is movably mounted on the assembly seat through a bearing, a crank is connected to the crank of the crankshaft, a connector is mounted on the crank through a pin shaft, and the connector is fixedly connected to the tobacco leaf clamping mechanism.

[0008] The crankshaft end extends to the outside of the assembly seat, and the crankshaft end extending to the outside of the assembly seat is provided with a pulley.

[0009] The tobacco leaf clamping mechanism is composed of a clamping shell, a pull rod and a splint. The clamping shell is installed with pull rods in parallel, and multiple splints are provided on the pull rods. Nuts are threadedly installed on the ends of the pull rods outside the splints. The clamping shell is fixedly connected to the spring and fixedly connected to the connecting head through the connecting seat.

[0010] The clamping shell is symmetrically provided with supporting slide grooves; the two end heads of the clamping plate are respectively provided with limiting slide heads, and the limiting slide heads are slidably connected with the supporting slide grooves.

[0011] A baffle is movably mounted on the clamping shell on one side of the nut through a hinge, and buckles are movably mounted on both ends of the baffle through pins; a stop pin is provided on the clamping shell on the inner side of the baffle, and the stop pin is engaged with the buckle to fix the baffle.

[0012] Furthermore, the plywood is provided with hanging rods, and pin holes are provided between the hanging rods; the hanging rods and the pin holes between two adjacent plywoods are plug-connected.

[0013] The beneficial effects of the present invention are:

[0014] This tobacco leaf vibrating impurity removal device uses a crankshaft and a spring to vibrate the tobacco leaves clamped in the tobacco leaf clamping mechanism. The vibration and the impurities' own gravity remove impurities from between the leaves. Because gravity is directed downward, impurities in the tobacco leaves are ensured to move downward during the vibration process, ensuring that the impurities are gradually removed through the vibration, making it difficult for impurities to be left behind. This eliminates the need for manual sorting of remaining impurities, effectively reduces visual fatigue, and effectively removes impurities between tobacco leaves. This solves the problem of existing impurity removal methods that easily cause visual fatigue and easily miss impurities. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The tobacco leaf vibration impurity removal device is composed of an assembly base 1, a spring sleeve 2, a tobacco leaf clamping mechanism, a spring 3, a crankshaft 4, a crank 5 and a connector 6. The assembly base 1 is a rectangular body, and the four corners of the bottom of the assembly base 1 are respectively provided with spring sleeves 2; a tobacco leaf clamping mechanism for clamping tobacco leaves is provided below the assembly base 1, and the tobacco leaf clamping mechanism is connected to the spring sleeve 2 through the spring 3; a crankshaft 4 is movably mounted on the assembly base 1 through a bearing, a crank 5 is connected to the crank of the crankshaft 4, and a connector 6 is mounted on the crank 5 through a pin, and the connector 6 is fixedly connected to the tobacco leaf clamping mechanism. The function of the crankshaft 4 is to drive the crank 5 to rotate during the rotation of the crankshaft 4, thereby driving the connector 6 on the crank 5 to reciprocate up and down, thereby driving the tobacco leaf clamping mechanism to reciprocate up and down through the connector 6, thereby driving the tobacco leaf clamping mechanism and the tobacco leaves clamped on the tobacco leaf clamping mechanism to shake, and removing impurities between the tobacco leaves through the shaking of the tobacco leaves and the gravity of the impurities themselves. Since gravity is directed downward, when the tobacco leaves are shaken, impurities move downward under the action of gravity, which can effectively remove impurities and prevent them from remaining. This effectively solves the problem of visual fatigue and easy residue left behind when picking out impurities. The function of spring 3 is to suppress the upward speed of the tobacco leaf clamping mechanism and accelerate the downward speed of the tobacco leaf clamping mechanism through spring 3. By suppressing the upward speed of the tobacco leaf clamping mechanism, the upward movement of impurities is slowed down, and when the tobacco leaves stop, the impurities are not likely to move upward under inertia; by accelerating the downward speed of the tobacco leaf clamping mechanism, the impurities move downward quickly, and when the tobacco leaves stop, the impurities can still move downward for a distance under inertia, thereby ensuring the removal of impurities through multiple shaking.

[0025] The end of the crankshaft 4 extends outside the assembly base 1. A pulley 7 is mounted on the end of the crankshaft 4 extending outside the assembly base 1. Pulley 7 is connected to a power machine via a belt. The power machine can be any of an electric motor, an internal combustion engine, a pneumatic motor, or a hydraulic motor. The power machine energy, via the belt, drives pulley 7 to rotate, thereby driving the crankshaft 4.

[0026] The tobacco leaf clamping mechanism consists of a clamping housing 8, a pull rod 9, and a clamping plate 10. The clamping housing 8 is equipped with pull rods 9 in parallel, and multiple clamping plates 10 are provided on the pull rod 9. Nuts 11 are threadedly installed on the ends of the pull rods 9 outside the clamping plates 10. The clamping housing 8 is fixedly connected to the spring 3 and fixedly connected to the connector 6 through the connecting seat 12. The pull rod 9 is connected to any one of a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, and a screw pair to pull the pull rod 9 to move. As the pull rod 9 moves, the clamping plates 10 are pulled closer together through the nut 11. The tobacco leaves are clamped by the clamping plates 10 that are close to each other, and the tobacco leaves are fixed to the tobacco leaf clamping device, so that the tobacco leaf clamping device can drive the tobacco leaves to shake when it shakes.

[0027] The clamping housing 8 is symmetrically provided with support chutes 13; limit sliders 14 are provided at both ends of the clamping plate 10, and the limit sliders 14 are slidably connected to the support chutes 13. The support chutes 13 are open at one end and closed at the other end, so that the clamping plate 10 can be removed from the clamping housing 8, thereby removing residues between the clamping plates and between the clamping plates and the clamping housing 8, ensuring that the movement of the clamping plates 10 is not affected, thereby ensuring that the clamping plates 10 can clamp the tobacco leaves tightly.

[0028] A baffle 16 is movably mounted on the clamping housing 8 on one side of the nut 11 via a hinge 15. Buckles 17 are movably mounted on both ends of the baffle 16 via pins. A stopper 18 is provided on the clamping housing 8 inside the baffle 16. The stopper 18 engages with the buckle 17 to secure the baffle 16. The baffle 16 seals the clamping housing 8, thereby preventing the clamp 10 from being easily separated from the clamping housing 8.

[0029] As an improvement, the clamping plates 10 are provided with hanging rods 19, and pin holes 20 are provided between the hanging rods 19; the hanging rods 19 and the pin holes 20 are plugged and connected between two adjacent clamping plates 10. The function of the hanging rods 19 is to temporarily store tobacco leaves between the clamping plates 10 through the hanging rods 19, thereby facilitating the assembly and clamping of the tobacco leaves.

[0030] Before operating the tobacco leaf vibrating impurity removal device, lift the buckle 17 to unlock the baffle 16 and flip it open. Once the baffle 16 is open, unscrew the nut 11 and remove the clamping plate 10. Clean the clamping housing 8, support chute 13, and clamping plate 10 separately to prevent any interference with the movement of the clamping plate 10 and ensure that the clamping plate 10 can firmly clamp the tobacco leaves. After cleaning, reinstall the clamping plate 10 and nut 11 in sequence. After flipping the baffle 16 downward, engage the buckle 17 with the stop pin 18 to secure the baffle 16.

[0031] When the tobacco leaf vibrating impurity removal device is in operation, the braided tobacco leaves are sequentially placed between the clamping plates. Once the tobacco leaves are in place, the pull rod 9 is pulled, thereby pulling the clamping plates 10 to clamp the tobacco leaves to the tobacco leaf clamping mechanism. Once the tobacco leaves are clamped, the crankshaft 4 is driven to rotate. The crankshaft 4, in turn, drives the tobacco leaf clamping mechanism to vibrate through the crank 5 and the connector 6, thereby vibrating the tobacco leaves. Combined with the action of the spring 3, impurities between the tobacco leaves are shaken out, thereby removing impurities from the tobacco leaves.

[0032] The tobacco leaf vibrating impurity removal device, through a crankshaft 4 in conjunction with a spring 3, can vibrate the tobacco leaves clamped on the tobacco leaf clamping mechanism. The vibration and the gravity of the impurities can remove impurities between the tobacco leaves. Because gravity is directed downward, impurities in the tobacco leaves can be moved downward during the vibration process, thereby ensuring that the impurities are gradually removed through the vibration, making it difficult for impurities to be left behind. This eliminates the need for manual sorting of remaining impurities, effectively reduces visual fatigue, and effectively removes impurities between tobacco leaves. This solves the problem that existing impurity removal methods easily cause visual fatigue and are prone to missing impurities.
