Description

Technical Field

[0001] This utility model relates to the field of tobacco processing equipment technology, and in particular to a tobacco material heating device. Background Technology

[0002] In the early stages of cigarette product development and maintenance, it is necessary to test the designed cigarette formula and simulate the production process of cigarette products on the production line to complete the production of samples in order to examine the degree to which its sensory quality design and objectives are initially consistent. The basic steps in the tobacco processing are tobacco leaf rehydration, flavoring, shredding, and tobacco drying.

[0003] For tobacco drying, researchers are currently miniaturizing the heating cylinder equipment on the production line to achieve rapid prototyping of designed products using a smaller amount of tobacco material. Conventional heating cylinders have their rotation drive located at either the inlet or outlet. If located at the inlet, it affects material feeding; if located at the outlet, the outlet cannot be fully opened, making cleaning the heating cylinder inconvenient. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a tobacco material heating device that can be used in the laboratory to heat and dry tobacco materials, and is easy to clean.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tobacco material heating device is provided, comprising a support, a cylinder, a heater, and a drive mechanism. The cylinder is mounted on the support, and the heater is installed on the cylinder for heating the cylinder. The drive mechanism includes a drive unit, a gear, and an annular rack. The annular rack is arranged around the outer periphery of the cylinder with the rotation axis of the cylinder as its axis. The drive unit is mounted on the support and is connected to the gear for transmission. The gear is located on the outer periphery of the cylinder and meshes with the annular rack. The drive unit can drive the gear to drive the annular rack and the cylinder to rotate relative to the support around the axis of the cylinder.

[0007] As a further embodiment of the tobacco material heating device, it also includes a first end cap and a second end cap. The support includes a first support frame and a second support frame. The cylinder is inclined and has a first end and a second end lower than the first end along its axial direction. The first end cap is located at the first end and is mounted on the first support frame. The second end cap is mounted on the second support frame adjacent to the second end. The first end cap has an inlet. The second end cap is spaced apart from the second end, which is the outlet. The drive unit is mounted on the first support frame. The cylinder can rotate relative to the first end cap and the second end cap.

[0008] As a further embodiment of the tobacco material heating device, it also includes a first bearing, a second bearing, and a material discharge chute. The cylinder body is connected to the first support frame near the first end via the first bearing, and the first end cap is fixedly connected to the first bearing. The cylinder body is connected to the second support frame near the second end via the second bearing. There is a gap between the second end cap and the second end. The material discharge chute is installed on the second support frame and located directly below the gap. The gap directly opposite the opening of the material discharge chute forms a receiving interface for receiving tobacco materials.

[0009] As a further embodiment of the tobacco material heating device, an arc-shaped seal is also included, which is connected to the outer periphery of the second end cap and the second bearing, and both ends of the seal are connected to the second support frame.

[0010] As a further embodiment of the tobacco material heating device, the second end cap is provided with an observation window coaxial with the cylinder and a transparent door for selectively sealing the observation window.

[0011] As a further embodiment of the tobacco material heating device, it also includes a plurality of lifting plates that are circumferentially spaced along the inner wall of the cylinder, the length of the lifting plates extending along the axial direction of the cylinder.

[0012] As a further embodiment of the tobacco material heating device, the lifting plate is a curved plate or a rake structure.

[0013] As a further embodiment of the tobacco material heating device, the cylinder also includes a handle protruding from the transparent door.

[0014] As a further embodiment of the tobacco material heating device, it also includes a feeding plate and a vibrating trough. The feeding plate is located outside the cylinder and adjacent to the inlet. One end of the vibrating trough is connected to the outlet of the feeding plate, and the other end extends to the inlet.

[0015] As a further embodiment of the tobacco material heating device, the feeding tray and the vibrating trough are arranged at an angle, with the height of one side of the feeding tray along its width direction being lower than the height of the other side, and the height of one side of the vibrating trough along its width direction being lower than the height of the other side.

[0016] Beneficial effects: In this invention, the drive unit can drive the cylinder to rotate relative to the support through the meshing of gears and annular racks, so that the cylinder reaches a set speed, thereby allowing the heater to uniformly heat the tobacco material inside the cylinder. Since the drive mechanism is located on the outer periphery of the cylinder, it avoids the drive mechanism extending into the cylinder and affecting the heating of the tobacco material and the cleaning of the cylinder, thus ensuring the heating effect of the tobacco material and the cleaning efficiency of the cylinder.

[0025] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationships shown in the accompanying drawings. They are used solely for ease of description and simplification of operation, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are merely used for distinction in description and have no special meaning.

[0029] like Figures 1 to 5 As shown, the tobacco material heating device of this embodiment includes a support 1, a cylinder 2, a heater 3, and a drive mechanism 4. The cylinder 2 is mounted on the support 1 and has an inlet and an outlet. The heater 3 is installed on the cylinder 2 to heat the cylinder 2. The drive mechanism 4 includes a drive unit 41, a gear 42, and an annular rack 43. The annular rack 43 is arranged around the outer periphery of the cylinder 2 with the rotation axis of the cylinder 2 as the axis. The drive unit 41 is mounted on the support 1 and is connected to the gear 42 for transmission. The gear 42 is located on the outer periphery of the cylinder 2 and meshes with the annular rack 43. The drive unit 41 can drive the gear 42 to drive the annular rack 43 and the cylinder 2 to rotate relative to the support 1 around the axis of the cylinder 2.

[0030] It is understood that when the drive unit 41 in this embodiment is started, it can drive the cylinder 2 to rotate relative to the support 1 through the meshing of the gear 42 and the annular rack 43, so that the cylinder 2 reaches the set speed, thereby allowing the heater 3 to uniformly heat the tobacco material inside the cylinder 2. Since the drive mechanism 4 is located on the outer periphery of the cylinder 2, it can avoid the drive mechanism 4 extending into the cylinder 2 and affecting the heating of the tobacco material and the cleaning of the cylinder 2, thus ensuring the heating effect of the tobacco material and the cleaning efficiency of the cylinder 2.

[0031] In this embodiment, the drive unit 41 is a motor; the heater 3 refers to a device with a heating function, which is conventional technology in the art. The heater 3 can be arranged in a fully enclosed or semi-enclosed form around the outer periphery of the cylinder 2. The heat generated by the heater 3 is transferred to the cylinder 2, and the tobacco material inside the cylinder 2 is indirectly heated and dried through the cylinder 2. In this embodiment, the inner wall of the cylinder 2 is made of stainless steel, the outer wall is made of rust-proof coating material, and the intermediate layer between the inner and outer walls is made of carbon steel.

[0032] The tobacco material heating device of this embodiment also includes a first end cover 51 and a second end cover 52. The bracket 1 includes a first support frame 11 and a second support frame 12. The cylinder 2 is inclined and has a first end and a second end below the first end along its axial direction. The first end cover 51 is located at the first end and is mounted on the first support frame 11. The second end cover 52 is mounted on the second support frame 12 adjacent to the second end. The first end cover 51 has an inlet. The second end cover 52 is spaced apart from the second end. The second end is the outlet. The drive unit 41 is mounted on the first support frame 11. The cylinder 2 can rotate relative to the first end cover 51 and the second end cover 52.

[0033] The first end cap 51 and the second end cap 52 are used to seal the two ends of the cylinder 2 along the axial direction. The inlet is set on the first end cap 51 to facilitate the conveying of tobacco material into the cylinder 2. The second end cap 52 is set at the second end and spaced apart from the second end, so that the second end is the outlet. The dried tobacco material can be smoothly discharged through the outlet by gravity.

[0034] Furthermore, the tobacco material heating device of this embodiment also includes a first bearing 61, a second bearing 62, and a material discharge trough 7. The cylinder 2 is connected to the first support frame 11 near the first end via the first bearing 61, and the first end cover 51 is fixedly connected to the first bearing 61. The cylinder 2 is connected to the second support frame 12 near the second end via the second bearing 62. There is a gap between the second end cover 52 and the second end. The material discharge trough 7 is installed on the second support frame 12 and is located directly below the gap. The gap directly opposite the opening of the material discharge trough 7 forms a receiving interface for receiving tobacco materials.

[0035] Under the influence of gravity, the dried tobacco material can fall directly into the opening of the discharge trough 7 after exiting from the second end, and then be discharged through the discharge trough 7.

[0036] For example, the inner holes of the first bearing 61 and the second bearing 62 are fixedly connected to the cylinder 2, the outer periphery of the first bearing 61 is fixed on the first support frame 11, the outer periphery of the second bearing 62 is fixed on the second support frame 12, the first end cap 51 is fixedly connected to one end of the first bearing 61 along its axial direction, and the second end cap 52 is fixed on the second support frame 12, so that the cylinder 2 can rotate relative to the first end cap 51 and the first support frame 11 via the first bearing 61 and relative to the second end cap 52 and the second support frame 12 via the second bearing 62.

[0037] like Figure 5 As shown, since there is a gap between the second end cap 52 and the second end, in order to prevent the tobacco material from being thrown out through the gap, the tobacco material heating device of this embodiment is also equipped with an arc-shaped sealing strip 8. The sealing strip 8 is connected to the outer periphery of the second end cap 52 and the second bearing 62, and the two ends of the sealing strip 8 are connected to the second support frame 12.

[0038] Specifically, the two edges of the seal 8 along its width direction overlap with the second end cover 52 and the second bearing 62 respectively, sealing the upper gap between the second end cover 52 and the second end. The arc-shaped groove of the second support frame 12 seals the lower gap between the second end cover 52 and the second end, thus leaving only the gap directly opposite the opening of the discharge chute 7 for material discharge.

[0039] Furthermore, such as Figure 2 and Figure 5 As shown, the second end cap 52 has an observation window 521 coaxial with the cylinder 2 along the axial direction of the cylinder 2, and a transparent hatch (not shown in the figure) for selectively sealing the observation window 521. By setting the observation window 521 and selectively sealing the observation window 521 with the transparent hatch, the inside of the cylinder 2 can be observed through the transparent hatch, and the inside of the cylinder 2 can be cleaned by opening the transparent hatch, which facilitates observation of the cleaning status inside the cylinder 2.

[0040] For example, one side of the transparent hatch is hinged to the second end cover 52, thereby allowing the transparent hatch to be opened or closed as needed. The transparent hatch is also locked to the second end cover 52 by a locking mechanism, which is a conventional technique in the art, such as a commonly used rotating pin and locking groove structure, and will not be described in detail here.

[0041] Furthermore, it also includes a handle (not shown in the figure), which protrudes from the transparent hatch to facilitate the opening and closing of the transparent hatch.

[0042] like Figure 4As shown, the tobacco material heating device of this embodiment also includes a plurality of lifting plates 91 that are spaced apart along the circumference of the cylinder 2 on the inner wall of the cylinder 2, and the length of the lifting plates 91 extends along the axial direction of the cylinder 2. By spaced apart multiple lifting plates 91 inside the cylinder 2, the tobacco material inside the cylinder 2 can be lifted up by the lifting plates 91 during the rotation of the cylinder 2, so that the tobacco material is heated more evenly.

[0043] Optionally, the lifting plate 91 can be a curved plate or a rake structure to improve the heating efficiency of the tobacco material.

[0044] Furthermore, the lifting plate 91 is divided into two sections along its length, one of which is a curved plate structure and the other is a rake nail structure. The curved plate structure and rake nail structure of two adjacent lifting plates 91 are staggered, which can further improve the uniformity of heating of tobacco materials.

[0045] Furthermore, the tobacco material heating device in this embodiment also includes a feeding tray 92 and a vibrating trough 93. The feeding tray 92 is located outside the cylinder 2 and adjacent to the inlet. One end of the vibrating trough 93 is connected to the outlet of the feeding tray 92, and the other end extends to the inlet. The tobacco material is poured into the feeding tray 92 and conveyed to the vibrating trough 93. Under the vibration of the vibrating trough 93, the tobacco material can quickly fall into the cylinder 2 through the inlet.

[0046] like Figure 3 As shown, the feeding disc 92 and the vibrating trough 93 are inclined, with one side of the feeding disc 92 being lower than the other side along its width, and the other side of the vibrating trough 93 being lower than the other side along its width. By inclining the feeding disc 92 and the vibrating trough 93, the tobacco material can slide towards the lower side of the feeding disc 92 and the vibrating trough 93 under the action of gravity, thereby improving the feeding efficiency of the tobacco material.

[0047] In this embodiment, the length of cylinder 2 is 600mm and the diameter (inner diameter) is 250mm, suitable for laboratory use. The processing capacity of the tobacco material heating device in this embodiment is 4-8kg / h.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and they should all be covered within the scope of the claims and specification of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
