Description

Technical Field

[0001] The present invention relates to the technical field of heating and non-combustible tobacco processing and manufacturing equipment, specifically to a horizontal canning device for heating and non-combustible tobacco pellets. Background Technology

[0002] Heated tobacco pellets are a new type of tobacco product that uses a special heating device to heat tobacco pellets containing tobacco pellets, releasing their aroma to the consumer. Currently, the flavoring technology for granular heated cigarettes is not yet stable. During the processing of granular heated cigarettes, flavorings and fragrances are significantly lost at high temperatures. Furthermore, the resulting tobacco pellets are highly hygroscopic and have poor flavor retention. During smoking, the direct contact between the tobacco pellets and the heating needle / plate causes rapid release of characteristic flavorings, resulting in insufficient, unstable, and short-lasting release of aroma components in granular heated cigarettes. This leads to poor consistency in the smoking experience, severely impacting both the smoking experience and product quality.

[0003] If the characteristic flavoring granules are filled into the cooling cavity section or other corresponding areas in the tobacco tube, so that the characteristic flavoring granules are not directly heated by the heating needle / plate, but are kept at a certain distance, the characteristic flavoring granules will release their aroma at a low temperature during inhalation. The characteristic flavoring granules will then have the characteristic of stable and continuous aroma release. Small-scale testing has already achieved the product's stable characteristics. However, current granule tobacco filling equipment cannot directly fill the characteristic flavoring granules into the cooling section. To achieve this, it is necessary to adaptively change the filling position of the tobacco granules in the tobacco tube to meet the requirements of tobacco granule distribution and filling in the tobacco tube under different conditions. However, the mainstream pellet filling equipment currently on the market has not yet taken this technical requirement into account. Furthermore, due to the large size and complex structure of the feeding, spreading, and related components of the existing filling equipment, the required assembly positions and spaces are also large. There is no space on the existing filling equipment to accommodate an additional station with such a large device. This necessitates adapting the research and development of tobacco pellet spreading and filling methods. Therefore, without changing the overall structure of the existing filling equipment, we can innovate and improve it on the original basis, adding the function of horizontal pellet filling, to develop a new type of technical equipment for heating granular cigarettes that meets market needs. The innovative research and development of this equipment can meet the needs of producing heating granular cigarettes with stable release of aroma components. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a horizontal filling device for heated, non-combustible tobacco pellets. Through a combined structure design of a pellet feeding hopper and a horizontal filling mechanism, the device utilizes the high-speed and stable transmission characteristics of the rotating drum to convey tobacco pipes into the drum grooves for arrangement. Simultaneously, tobacco pellets are introduced through the pellet feeding hopper into a pellet dispensing plate for portioned filling. Under the coordinated action of the filling cam and the ejector pin, the insertion depth of the tobacco pellets in the tobacco pipe is controlled by the stroke curve of the ejector pin in the filling cam groove. As the ejector pin contacts the working surface of the cam and... The needle generates force, causing the ejector pin to automatically, horizontally, and rapidly inject tobacco granules from the holes of the granule distribution disc into the designated process positions on the inner wall of the empty tobacco tube. This completes the filling process of tobacco granules repeatedly, enabling precise control over the injection volume, depth, and speed of granular heated non-combustible tobacco granules into the tobacco tube. This further ensures the filling effect of the tobacco granules in the tobacco tube, greatly improving the production efficiency of tobacco granule preparation in the granule filling machine, ensuring the stable release of aroma components from the tobacco granules, and maintaining stable product quality, thus meeting the needs of automated production.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A horizontal filling device for heated non-combustible tobacco pellets includes a pellet feeding bin (1), a horizontal filling mechanism (2), and a tobacco pipe (3). The pellet feeding bin includes a bin cover (11), a handle (12), a bin body (13), a feeding motor (14), a feeding roller (15), a pellet guide plate (17), a pellet discharge trough (16), and a pellet control nozzle (18). The top of the bin body is provided with a bin cover and a bin cover handle. The bottom of the bin body is provided with a bottom plate. The feeding motor is provided on the lower outer side. The feeding motor is connected to a feeding roller. The feeding roller has a long strip feeding groove (151). The bottom plate and below the feeding roller have a long strip pellet discharge trough. The lower part of the pellet discharge trough is directly opposite the pellet guide plate. The pellet guide plate has a pellet channel inside. The pellet guide plate is installed directly above the pellet distribution plate (24) in the horizontal filling mechanism. The arc surface at the lower end of the pellet guide plate matches the outer diameter of the pellet distribution plate.

[0007] Further, the horizontal filling mechanism (2) includes a drive shaft (21), a smoke pipe limiting baffle (22), a drum (23), a particle distribution disc (24), a ejector pin mounting disc (25), an ejector pin (26), a return spring (27), a filling cam (28), and a transmission gear (29). The drum, particle distribution disc, ejector pin mounting disc, and transmission gear are installed on the drive shaft in a front-to-back sequence. The drive shaft drives the horizontal filling mechanism to rotate counterclockwise through the transmission gear. An ejector pin and a return spring are installed on the ejector pin mounting disc. The return spring is sleeved on the outer periphery of the ejector pin. The ejector pin is axially parallel and aligned with the center of the drum groove on the outer periphery of the drum, and perpendicular to the working surface of the filling cam. The wheel is fixedly installed on the frame of the filling machine, and its axis is coaxial with the drive shaft. The working surface of the side of the filling cam is perpendicular to the drive shaft but does not rotate with the drive shaft. While the ejector pin rotates synchronously with the horizontal filling mechanism, it also performs axial movements of retraction and ejection under the control of the continuously and gradually changing working surface of the cam on the side of the filling cam. This synchronously realizes the seamless, continuous and rapid feeding and filling of the particles in the particle distribution plate into the set position point in the tobacco tube. After each action, the ejector pin is reset under the action of the return spring, following the side rotation curve of the filling cam. This automatically and continuously completes the filling cycle, thereby achieving the effect of vertical distribution and horizontal filling of tobacco particles.

[0008] Furthermore, the particle distribution plate (24) is provided with distribution holes, including radial holes (241) and axial holes (242). The radial holes and axial holes are connected and vertically arranged. The radial holes and axial holes are respectively arranged in correspondence with the ejector pin (26) and the drum groove to achieve the effect of vertical distribution and horizontal filling of tobacco particles.

[0009] Furthermore, the horizontal filling mechanism is a relatively independent component that can be connected to the filling machine's transmission system via a transmission gear and operate synchronously with the filling machine; the feeding roller has two elongated feeding grooves symmetrically opened along its axial direction, and under the drive of the feeding motor, it transports the particles to the particle guide plate; the particle feeding bin and the horizontal filling mechanism are respectively equipped with a smoke pipe limiting baffle (22) and a particle distribution plate (24), with an installation distance of about 45mm, forming a smoke pipe channel during operation, which plays a role in correction and positioning; a particle control air nozzle is installed at the rear end of the particle guide plate, which uses airflow to blow excess particles back to the filling area.

[0010] Furthermore, 24-40 cylindrical canning holes are evenly distributed on the outer periphery of the particle distribution plate. The distribution holes include radial holes and axial holes. The particle filling amount is set by setting the size of the distribution holes. The particle guide plate (17) is a hollow structure with an arc-shaped bottom. A buffer and leak-proof sealing gasket is provided between it and the particle distribution plate (24).

[0011] A method for operating a horizontal filling device for heated, non-combustible tobacco pellets includes the following steps:

[0012] Step S1: First, a suitable amount of tobacco pellets are pre-stored in the pellet feeding bin. When the horizontal filling mechanism has a pellet filling requirement, the feeding motor is started, which drives the feeding roller (15) with the long strip feeding groove to rotate. The feeding roller transports the tobacco pellets from the pellet feeding bin to the pellet channel in the pellet guide plate (17) and covers the tobacco pellets on the distribution hole on the outer circle of the pellet distribution plate (24).

[0013] Step S2: When the main drive system of the filling machine drives the transmission gear to rotate, the transmission gear drives the drum drive shaft to rotate, so that the drum drives the smoke pipe and the particle distribution plate to contact and pass under the particle guide plate. At this time, the distribution hole on the outer periphery of the particle distribution plate will be filled with particles. In order to prevent excess particles from spilling out, a particle control air nozzle is installed at the rear end of the particle guide plate to blow excess particles back into the particle guide plate.

[0014] Step S3: In the horizontal filling mechanism, the tobacco particles in the distribution holes of the tobacco pipe and particle distribution plate, the drum, the ejector pin mounting plate, the ejector pin, and the return spring rotate counterclockwise together with the drive shaft. The filling cam mounted on the filling machine frame is fixed, but its center and the ejector pin mounting plate are on the same axis of the drive shaft. While the ejector pin rotates synchronously with the horizontal filling mechanism and the drive shaft, it also moves axially back and forth under the control of the cam working surface on the side of the filling cam. This quickly and accurately drives the tobacco particles horizontally into and fills them into the position area set in the empty tobacco pipe. After each action, the ejector pin returns to its original position under the action of the return spring, following the rotation curve of the filling cam. This automatically and continuously completes the filling cycle, thereby achieving the purpose of vertical distribution and horizontal filling of tobacco particles.

[0015] This invention discloses a horizontal filling device for heated, non-combustible tobacco pellets. Through a combined structural design of a pellet feeding hopper and a horizontal filling mechanism, it organically integrates the conveying and filling of tobacco pellets and the tobacco tube, achieving continuous and high-speed movement of the tobacco pellets and the tobacco tube. With the coordinated action of the pellet distribution plate, filling cam, and ejector pin, it changes the traditional method of filling tobacco pellets vertically within the tobacco tube. It further enables precise control of the filling method, depth, and speed of the tobacco pellets within the tobacco tube, fully ensuring the filling effect of the tobacco pellets in the tobacco tube. This achieves the goal of vertical feeding and horizontal filling of tobacco pellets, greatly improving the production efficiency of tobacco pellet preparation in pellet filling machines, ensuring the stable release of aroma components from the tobacco pellets, and maintaining stable product quality, thus meeting the needs of automated production.

The drum 23, pellet distribution disc 24, ejector pin mounting disc 25, and transmission gear 29 are installed sequentially on the drive shaft 21. The drive shaft 21 drives the horizontal filling mechanism 2 to rotate counterclockwise (R) through the transmission gear 29. The ejector pin 26 and the return spring 27 are installed on the ejector pin mounting disc 25. The return spring 27 is sleeved on the outer periphery of the ejector pin 26. The ejector pin 26 is axially parallel and aligned with the center of the drum groove on the outer periphery of the drum 23, and perpendicular to the working surface of the filling cam 28. The filling cam 28 is fixedly installed on the can. On the loading frame, its axis is coaxial with the drive shaft 21. The side working surface of the filling cam 28 is perpendicular to the drive shaft 21 but does not rotate with the drive shaft 21. While the ejector pin 26 rotates synchronously with the horizontal filling mechanism 2, it also performs axial movements of retraction and ejection under the control of the continuously changing working surface of the cam on the side of the filling cam 28. This synchronously realizes the seamless, continuous and rapid feeding and filling of the particles in the particle distribution disk 24 into the set position point in the tobacco tube 3. After completing each action, the ejector pin 26 is reset under the action of the return spring 27 along the side rotation curve of the filling cam 28, automatically and continuously completing the filling cycle, thereby achieving the effect of vertical feeding and horizontal filling of tobacco particles.

[0026] Furthermore, the pellet distribution disc 24 is provided with distribution holes, including radial holes 241 and axial holes 242. The radial holes 241 and axial holes 242 are connected and vertically arranged. The radial holes 241 and axial holes 242 are respectively arranged in correspondence with the ejector pin 26 and the drum groove to achieve the effect of vertical feeding and horizontal filling of tobacco pellets.

[0027] The horizontal filling mechanism 2 is a relatively independent component that can be connected to the filling machine's transmission system via the transmission gear 29 and operate synchronously with the filling machine.

[0028] The feeding roller 15 has two elongated feeding grooves 151 symmetrically opened along its axis, and under the drive of the feeding motor 14, it transports the particles to the particle guide plate 17.

[0029] The pellet feeding hopper 1 and the horizontal filling mechanism 2 are respectively equipped with a smoke pipe limiting baffle 22 and a pellet distribution plate 24, with an installation distance of 45mm. During operation, they form a smoke pipe channel, which serves as a correction and positioning function.

[0030] A particle control nozzle 18 is installed at the rear end of the particle guide plate 17 to use airflow to blow excess particles back to the filling area.

[0031] There are 32 cylindrical canning orifices evenly distributed on the outer periphery of the granule dispensing disk 24. The dispensing orifices include radial orifices 241 and axial orifices 242. The filling amount of granules is set by setting the size of the dispensing orifices.

[0032] The particle guide plate 17 has a hollow structure with an arc-shaped bottom, and a sealing gasket with buffer and leak prevention is installed between it and the particle distribution plate 24.

[0033] A horizontal filling device for heated, non-combustible tobacco pellets, the working process / working principle of which is as follows:

[0034] S1: First, a suitable amount of tobacco pellets are pre-stored in the pellet feeding bin. When the horizontal filling mechanism has a pellet filling requirement, the feeding motor 14 is started, which drives the feeding roller 15 with the long strip feeding groove 151 to rotate. The feeding roller transports the tobacco pellets from the pellet feeding bin to the pellet channel in the pellet guide plate 17 and covers the tobacco pellets on the distribution hole on the outer circle of the pellet distribution plate 24.

[0035] S2: When the main drive system of the filling machine drives the transmission gear 29 to rotate, the transmission gear 29 drives the drum drive shaft 21 to rotate, so that the drum 23 drives the smoke pipe 3 and the particle distribution disk 24 to contact and pass under the particle guide plate 17. At this time, the distribution hole on the outer periphery of the particle distribution disk 24 will be filled with particles. In order to prevent excess particles from spilling out, a particle control air nozzle 18 is installed at the rear end of the particle guide plate 17 to blow excess particles back into the particle guide plate.

[0036] S3: In the horizontal filling mechanism 2, the tobacco particles in the distribution holes of the tobacco pipe 3 and the particle distribution plate 24, the drum 23, the ejector pin mounting plate 25, the ejector pin 26, and the return spring 27 rotate counterclockwise (R) together with the transmission shaft 21. The filling cam 28 installed on the filling machine frame is fixed, but its center and the ejector pin mounting plate 25 are on the same axis of the transmission shaft 21. While the ejector pin 26 rotates synchronously with the horizontal filling mechanism and the transmission shaft 21, it also makes a retraction and extension axial movement under the control of the cam working surface on the side of the filling cam 28, so as to quickly and accurately drive the tobacco particles horizontally into and fill them into the position area set by the empty tobacco pipe 3. After each action, the ejector pin 26 returns to the rotation curve of the filling cam 28 under the action of the return spring 27, automatically and continuously completing the filling cycle, thereby achieving the purpose of vertical feeding and horizontal filling of tobacco particles.
