Description

Technical Field

[0001] This invention relates to equipment for manufacturing disordered heated cigarettes, and more specifically, to a device for preventing void defects in disordered heated cigarettes during the feeding process of a laminating machine. Background Technology

[0002] The disordered heated cigarette manufacturing process involves cutting tobacco leaves into disordered shreds, blending and flavoring them, rolling and compounding them to produce heated cigarettes. The feeding process in disordered heated cigarette production refers to the process of the cigarette entering the cutting drum from the hopper. As the cigarette moves downwards within the hopper, it experiences prolonged mutual compression and friction, internal circulation under the action of the rotating drum, and electrostatic interference. This causes the thin tobacco shreds at the cigarette end to easily move outwards during this process, forming voids and severely affecting the quality of the cigarette.

[0003] Existing technologies typically use laser or visual inspection to detect and remove empty cigarettes in subsequent processes. While this can prevent empty cigarettes from flowing into the next process to some extent, it does not solve the problem of empty cigarettes, resulting in some defective cigarettes entering the market. Furthermore, there is a risk of overload in the removal process; an excessively high removal rate affects raw material consumption and increases production costs. Summary of the Invention

[0004] This invention overcomes the shortcomings of the prior art and provides a device to prevent empty head defects from occurring in the feeding process of the compounding machine when cigarettes are heated in a disorderly manner. It is expected to solve the problems of empty head defects caused by prolonged mutual squeezing, friction and electrostatic interference when cigarettes move downward in the hopper, resulting in reduced cigarette quality, high raw material consumption and high production costs.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A device for preventing air gaps in the feeding process of a cigarette blending machine during disordered heating of cigarettes includes a hopper base and a smoke baffle plate hinged to the upper end of the hopper base on the opposite side of the cigarette blending machine hopper via a smoke baffle plate mounting seat. A stirring roller drive shaft is fixedly installed on the outer side of the hopper base, and a cylindrical stirring roller with a slanted end face or curved surface cam disk is fixedly connected to the output end of the stirring roller drive shaft on the inner side of the hopper base. The stirring roller drive shaft is connected to the main transmission system. A smoke baffle plate top column is fixedly installed on the smoke baffle plate, and the smoke baffle plate top column contacts the circumferential surface of the cam disk of the cylindrical stirring roller. A tension assembly is connected between the bottom of the smoke baffle plate and the hopper base. Preferably, the tension assembly is fixedly installed on the lower part of the lower baffle of the cigarette blending machine to prevent the tension assembly from damaging the cigarettes during movement.

[0007] The preferred tension component includes a first mounting base fixedly installed on the hopper base, and a second mounting base fixedly installed on the lower part of the smoke baffle and corresponding to the first mounting base, with a return spring connected between the first mounting base and the second mounting base.

[0008] The preferred smoke baffle has a friction pad at the top of the column to prevent the contact friction block from wearing out too quickly.

[0009] The top of the preferred smoke baffle can also be equipped with a ball screw to ensure that the top of the top of the top column and the cam plate of the smoke stirring roller are in rolling friction, preventing excessive wear due to contact.

[0010] The preferred stirring roller is a curved cam disc stirring roller with multiple curved surfaces on its end face. The frequency of the smoke baffle hitting the cigarette can be controlled by increasing or decreasing the number of curved surfaces on the multi-curved stirring roller.

[0011] The preferred smoke baffle is made of anti-static transparent PVC material, which facilitates observation of the inside of the cigarette laminating machine hopper.

[0012] The preferred method connects the agitator roller and its drive shaft via a hex socket head cap screw, making replacement simple when wear affects the normal setting trajectory.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: by the reciprocating up-and-down slapping motion of the baffle plate, the tobacco shreds that have moved outward during the downward movement of the cigarette in the hopper due to mutual squeezing, friction, cyclic movement, and electrostatic interference adsorption are slapped back into the cigarette, thereby avoiding the occurrence of hollow head defects. Moreover, the present invention has a simple structure and is relatively easy to maintain. The present invention does not require additional power when installed on the original machinery, saving enterprise costs and improving product quality. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] Example 1

[0023] like Figures 1-4 As shown, a device for preventing empty head defects in the feeding process of a cigarette laminating machine due to disordered heating of cigarettes is disclosed. The device comprises a hopper base 1, a running component, a smoke baffle 8, a smoke baffle mounting seat 10, and a tension component. The hopper base 1 is a side wall of the cigarette laminating machine hopper 13. A cutting drum 16 and a rotating drum 17 cooperating with the cutting drum 16 are rotatably mounted in the lower part of the hopper 13. The running component is rotatably mounted in the middle of the hopper base 1 inside the hopper 13, above the cutting drum 16 and the rotating drum 17. A smoke baffle 8 is provided on the opposite side of the hopper base 1. The upper end of the smoke baffle 8 is hinged to the cigarette laminating machine hopper 13 via the smoke baffle mounting seat 10. A tension component connects the bottom of the smoke baffle 8 to the hopper base 1. The smoke baffle 8 is made of anti-static transparent PVC material, facilitating observation of the interior of the cigarette laminating machine hopper 13.

[0024] The operating components include a stirring roller drive shaft 3 fixedly installed on the outside of the hopper base 1, and a stirring roller 2 fixedly connected to the output end of the stirring roller drive shaft 3 on the inside of the hopper base 1. The front end of the cam disk of the stirring roller 2 has an inclined end face. The stirring roller 2 and the stirring roller drive shaft 3 are connected by an internal hex screw. When the stirring roller 2 with the inclined end face wears down due to long-term operation and affects the normal set trajectory, it is easy to replace. The operating components also include a smoke baffle top column 4, which is fixedly installed on the smoke baffle 8. A friction pad 5 is fixedly installed on the top of the smoke baffle top column 4. The friction pad 5 contacts the circumferential surface of the inclined end face of the cam disk of the stirring roller 2 and rotates relative to it along the circumference of the inclined end face of the stirring roller 2.

[0025] The stirring roller drive shaft 3 has a connecting gear that meshes with the gear of the main transmission system. By controlling the gear ratio between the connecting gear on the stirring roller drive shaft 3 and the gear of the main transmission system, the rotation speed ratio of the stirring roller 2 can be adjusted, the frequency of the smoke baffle 8 striking the cigarette stick 12 can be controlled, and the amplitude of the striking can be controlled by controlling the angle of the inclined surface of the stirring roller 2. The stirring roller drive shaft 3 can also be connected to the main transmission system via a belt.

[0026] The lower end of the smoke baffle 8 extends below the lower end of the lower baffle 11 of the cigarette laminating machine, and the tensioning component is located below the lower baffle 11 of the cigarette laminating machine to prevent the tensioning component from damaging the cigarette 12 during movement. The lower baffle 11 of the cigarette laminating machine has the function of reducing the circulating movement of the cigarette and bringing the cigarette towards the cutting drum 16.

[0027] The tensioning assembly includes a first mounting seat 6 fixedly installed on the lower part of the cigarette compounding machine hopper 13 of the lower baffle 11, and a second mounting seat 9 fixedly installed on the lower part of the smoke baffle 8 and corresponding to the first mounting seat 6. A return spring 7 is connected between the first mounting seat 6 and the second mounting seat 9. The return spring 7 ensures that the top column 4 of the smoke baffle and the inclined end face of the stirring roller 2 always remain in contact.

[0028] Figure 6 This refers to the distribution of cigarettes in the hopper of the cigarette laminating machine, and also the operating state of the device used to prevent empty head defects in the feeding process of the cigarette laminating machine.

[0029] Example 2

[0030] This embodiment is a further improvement on embodiment 1; such as Figure 5 As shown, the friction pad 5 of the top column 4 of the smoke baffle can be replaced with a ball screw 15 to ensure the smooth operation of the top column 4 of the smoke baffle and the stirring roller 2 and prevent excessive contact wear.

[0031] The stirring roller is a curved cam disc stirring roller 14. The frequency of the smoke baffle 8 striking the cigarette stick 12 can be controlled by increasing or decreasing the curvature on the curved cam disc stirring roller 14.

[0032] Specific usage method: During operation, the main transmission system gear drives the smoke-stirring roller drive shaft 3 and the smoke-stirring roller 2 to rotate. The friction pad 5 or ball screw 15 on the smoke-baffle top column 4 moves relative to the circumference of the smoke-stirring roller 14 along the inclined surface or curved surface cam disc of the smoke-stirring roller 2. The smoke-baffle top column 4 drives the smoke-baffle 8 to reciprocate along the smoke-baffle mounting base 10 as the origin. When the smoke-baffle top column 4 contacts the lowest point of the inclined surface or curved surface of the smoke-stirring roller 2 or the curved surface cam disc of the smoke-stirring roller 14, the smoke-baffle 8 is parallel to the hopper base 1, and the return spring 7 generates tension to make... The top post 4 of the smoke baffle plate is in close contact with the stirring roller 2, and the smoke baffle plate 8 is in contact with the end face of the cigarette stick 12. When the top post 4 of the smoke baffle plate contacts the highest point of the curved or inclined surface of the stirring roller 2 or the curved cam disc stirring roller 14, the smoke baffle plate 8 opens outward along the smoke baffle plate mounting seat 10, and the return spring 7 is opened by the pulling force of the smoke baffle plate 8. The opening and closing reciprocating motion of the smoke baffle plate 8 beats the end of the cigarette stick 12, and the tobacco shreds that have moved outward during the mutual squeezing and friction when the cigarette stick 12 moves downward in the hopper are beaten back into the interior of the cigarette stick 12, thereby avoiding the occurrence of hollow head defects.

[0033] Although the invention has been described herein with reference to illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of this disclosure. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
