Abstract
Description
Technical Field
[0001] This application relates to the field of cigarette processing technology, and in particular to a device for loosening thin tobacco shreds. Background Technology
[0002] Heated cigarettes are a new type of electronic cigarette. They use a heating device to heat the cigarette to a certain temperature without igniting the tobacco. The tobacco is heated enough to emit smoke, resulting in a taste closer to that of a real cigarette. Heated cigarettes, on the other hand, contain thin sheets of tobacco. To enhance the flavor, a large amount of flavorings and fragrances are sprayed onto these sheets, resulting in a high sugar content and a tendency for the tobacco to stick together. This can cause equipment blockage during the cigarette rolling process, leading to downtime and affecting production stability.
[0003] In related structures, a thin tobacco sheet loosening device is typically used to loosen the thin tobacco sheets. This device usually includes two needle rollers rotating in opposite directions. When the thin tobacco sheets fall between the two needle rollers, they can be broken up by the two rollers. However, relying solely on two needle rollers rotating in opposite directions is not very effective at loosening thin tobacco sheets. Utility Model Content
[0004] Therefore, it is necessary to provide a thin tobacco loosening device that can improve the loosening effect of thin tobacco sheets.
[0005] A thin sheet tobacco loosening device includes a screening mechanism, a first loosening mechanism, and a second loosening mechanism. The screening mechanism includes a frame and a screen mounted on the frame, with a through hole at the bottom of the frame. The first loosening mechanism is located at one end of the screening mechanism and includes a first needle roller and a second needle roller. The first needle roller has a plurality of first elastic wire nails, and the second needle roller has a second elastic wire nail. The first and second elastic wire nails are staggered, and the first and second needle rollers can rotate towards each other. The second loosening mechanism is located within the screening mechanism. At the other end, the second loosening mechanism includes a third needle roller and a fourth needle roller. The third needle roller is provided with multiple third elastic wire nails, and the fourth needle roller is provided with multiple fourth elastic wire nails. The third and fourth elastic wire nails are arranged alternately, and the third and fourth needle rollers can rotate towards each other. The thin tobacco shreds are first broken up by the first and second needle rollers in the first loosening mechanism, and then loosened on the screen of the screening mechanism. Some of the loosened thin tobacco shreds are discharged through the through holes, and the other part of the thin tobacco shreds are further broken up by the third and fourth needle rollers in the second loosening mechanism.
[0006] In one embodiment, the number of first and second spring screws is equal to M, the number of third and fourth spring screws is equal to N, and M > N; and / or, the length of the first and second spring screws is equal to M. The length of the third and fourth threaded pins are equal and both are... ,and > .
[0007] In one embodiment, the thin tobacco loosening device further includes a support, a screening mechanism mounted on the top of the support along the height direction z; a first loosening mechanism mounted on the top of the screening mechanism along the height direction z of the support, and the first loosening mechanism having a first discharge port facing the screening mechanism; and a second loosening mechanism mounted on one side end face of the support along the length direction x of the support, and the second loosening mechanism having a second feed port facing the screening mechanism.
[0008] In one embodiment, the thin tobacco loosening device further includes a first receiving hopper and a second receiving hopper, a first receiving space is provided below the height direction z of the support, the second receiving hopper is located in the first receiving space and is disposed toward the through hole; the second loosening mechanism has a second discharge port, and the second receiving hopper is located below the second discharge port along the height direction z of the support.
[0009] In one embodiment, the thin tobacco loosening device further includes an electrical box, a support frame is provided at the bottom of the bracket along its height direction z, the electrical box is installed on the support frame, and the support frame and the first accommodating space are arranged along the length direction y of the bracket.
[0010] In one embodiment, the first loosening mechanism includes a hopper, a first support plate, and a second support plate. One end of the hopper has a first inlet and a first outlet. The first inlet is located above the first outlet along the height direction z of the support. The two sides of the hopper along the width direction y of the support are connected to the support through the first support plate and the second support plate, respectively.
[0011] In one embodiment, the first loosening mechanism further includes a plurality of support rods disposed inside the hopper and positioned above the first needle roller and the second needle roller along the height direction z of the support. The two ends of each support rod are respectively connected to the inner walls of the two opposite sides of the hopper.
[0012] In one embodiment, the first loosening mechanism further includes a detector located above the first and second needle rollers along the height direction z of the support and mounted on the inner wall of the hopper; the detector is used to detect whether the thin tobacco shreds in the hopper have reached a predetermined position.
[0013] In one embodiment, along the height direction of the support, the hopper includes an inlet section, a guide section and a mating section connected sequentially from top to bottom; the inlet section and the guide section are set at an angle, and the first needle roller and the second needle roller are rotatably mounted on the mating section.
[0014] In one embodiment, a plurality of first elastic pins form a first edge at one end away from the first needle roller, and the cross-sectional shape of the inner wall on one side of the mating section matches and gap-fits the shape of at least a portion of the first edge opposite thereto; a plurality of second elastic pins form a second edge at one end away from the second needle roller, and the cross-sectional shape of the inner wall on the other side of the mating section matches and gap-fits the shape of at least a portion of the second edge opposite thereto.
[0015] Compared with existing technologies, the thin tobacco flake loosening device provided in this application, by setting up a screening mechanism, a first loosening mechanism, and a second loosening mechanism, allows the thin tobacco flakes to be first loosened by a first needle roller and a second needle roller, followed by a screening process in the screening mechanism. Some clumps of thin tobacco flakes pass through the screen and are discharged through the through-holes, while other clumps cannot pass through the screen and flow to the second loosening mechanism, where they are further loosened by a third and fourth needle roller. In other words, the thin tobacco flakes undergo two loosening processes and one screening process, which helps to fully loosen the thin tobacco flakes and prevents downstream equipment blockage and downtime caused by the sticking of thin tobacco flakes, thereby improving the stability of heated cigarette production.

[0029] Please see Figure 1 , Figure 4 and Figure 6 This application provides a thin-sheet tobacco loosening device 100, which includes a screening mechanism 110, a first loosening mechanism 120, and a second loosening mechanism 130. The screening mechanism 110 includes a frame 111 and a screen 112 mounted on the frame 111, with a through hole 113 at the bottom of the frame 111. The first loosening mechanism 120 is located at one end of the screening mechanism 110 and includes a first needle roller 121 and a second needle roller 122. The first needle roller 121 has a plurality of first elastic wire nails 1211, and the second needle roller 122 has second elastic wire nails 1221. The first elastic wire nails 1211 and the second elastic wire nails 1221 are staggered, and the first needle roller 121 and the second needle roller 122 can rotate towards each other. The second loosening mechanism 130 is located at the other end of the screening mechanism 110. The second loosening mechanism 130 includes a third needle roller 131 and a fourth needle roller 132. The third needle roller 131 is provided with a plurality of third elastic wire nails 1311, and the fourth needle roller 132 is provided with a plurality of fourth elastic wire nails 1321. The third elastic wire nails 1311 and the fourth elastic wire nails 1321 are staggered, and the third needle roller 131 and the fourth needle roller 132 can rotate towards each other. The thin tobacco shreds are first broken up by the first needle roller 121 and the second needle roller 122 in the first loosening mechanism 120, and then loosened on the screen 112 of the screening mechanism 110. Some of the loosened thin tobacco shreds are discharged through the through hole 113, and the other part of the thin tobacco shreds are further broken up by the third needle roller 131 and the fourth needle roller 132 in the second loosening mechanism 130.
[0030] Understandably, by setting up the screening mechanism 110, the first loosening mechanism 120, and the second loosening mechanism 130, the thin tobacco flakes are first broken up by the first needle roller 121 and the second needle roller 122. Then, they are screened once in the screening mechanism 110. Some of the clumps of thin tobacco flakes are screened by the screen 112 and discharged through the through hole 113. The other clumps of thin tobacco flakes cannot pass through the screen 112 and flow to the second loosening mechanism 130. Then, they are further broken up by the third needle roller 131 and the fourth needle roller 132 in the second loosening mechanism 130. In other words, the thin tobacco flakes undergo two breaking up and one screening and diversion, which helps to fully break up the thin tobacco flakes and prevent problems such as material blockage and equipment shutdown caused by the thin tobacco flakes sticking together. This helps to improve the stability of heated cigarette production.
[0031] In one embodiment, the number of first spring wire nails 1211 is equal to the number of second spring wire nails 1221, both being M, and the number of third spring wire nails 1311 is equal to the number of fourth spring wire nails 1321, both being N, where M > N. Since the thin tobacco flakes are first broken up by the first needle roller 121 and the second needle roller 122 in the first loosening mechanism 120, and then screened and divided in the screening mechanism 110, the divided portion of the thin tobacco flakes is further broken up by the third needle roller 131 and the fourth needle roller 132 in the second loosening mechanism 130. Therefore, the amount of thin tobacco flakes at the first loosening mechanism 120 is greater than the amount of thin tobacco flakes at the second loosening mechanism 130. By setting M > N, the first and second spring wire nails 1211 and 1221 are more densely packed than the third and fourth spring wire nails 1311 and 1321, thereby making the first loosening mechanism 120 more efficient at loosening the thin tobacco shreds than the second loosening mechanism 130. In other words, the loosening ability of the first and second loosening mechanisms 120 and 130 on the thin tobacco shreds is matched with the amount of thin tobacco shreds at the first and second loosening mechanisms 120 and 130.
[0032] In another embodiment, the length of the first spring screw 1211 is equal to the length of the second spring screw 1221, and both are... The length of the third spring screw 1311 is equal to the length of the fourth spring screw 1321, and both are... ,and > Understandably, this can be achieved through settings. > This design makes it easier for the first elastic bar 1211 and the second elastic bar 1221 to break up relatively large clumps of thin tobacco, and for the third elastic bar 1311 and the fourth elastic bar 1321 to break up relatively small clumps of thin tobacco. This improves the ability of the thin tobacco loosening device 100 to loosen clumps of thin tobacco of different volumes.
[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, the thin tobacco flake loosening device also includes a support 140, a screening mechanism 110 mounted on top of the support 140 along the height direction z of the support 140; a first loosening mechanism 120 mounted on top of the screening mechanism 110 along the height direction z of the support 140, and the first loosening mechanism 120 having a first discharge port 124 facing the screening mechanism 110; and a second loosening mechanism 130 mounted on one side end face of the support 140 along the length direction x of the support 140, and the second loosening mechanism 130 having a second feed port 133 facing the screening mechanism 110. The support 140 serves as a supporting structure, supporting and mounting the screening mechanism 110, the first loosening mechanism 120, and the second loosening mechanism 130. The thin tobacco flakes initially loosened by the first loosening mechanism 120 fall onto the screening mechanism 110 under gravity, passing through the first discharge port 124. Next, the relatively small clumps of tobacco leaves that have been screened and separated by the screening mechanism 110 enter the second loosening mechanism 130 through the second feed inlet 133 for a second loosening.
[0034] Specifically, in one embodiment, multiple square steel bars are connected by bolts, and the bracket 140 includes a mounting frame 143 and six support rods 144 for supporting the mounting frame 143. Each support rod 144 has a universal flat bottom support 145 at its bottom, which is used to level the bracket 140.
[0035] In one embodiment, such as Figure 1 As shown, the thin tobacco flake loosening device 100 also includes a first receiving hopper 150 and a second receiving hopper 160. A first receiving space 141 is located below the support 140 in the height direction z. The second receiving hopper 160 is located in the first receiving space 141 and faces the through hole 113. The second loosening mechanism 130 has a second discharge port 134, and the second receiving hopper 160 is located below the second discharge port 134 along the height direction z of the support 140. The first receiving hopper 150 is used to receive the thin tobacco flakes that have passed through the screen 112 and the through hole 113. The second receiving hopper 160 is used to receive the thin tobacco flakes that have been loosened by the second loosening mechanism 130.
[0036] Furthermore, the bottom of the first receiving bucket 150 and the second receiving bucket 160 are respectively equipped with wheels to facilitate the movement of the first receiving bucket 150 and the second receiving bucket 160 by the staff.
[0037] In one embodiment, such as Figure 1 As shown, the thin tobacco loosening device also includes an electrical box 170. The support frame 142 is provided at the bottom of the bracket 140 along its height direction z. The electrical box 170 is installed on the support frame 142, and the support frame 142 and the first accommodating space 141 are arranged along the length direction y of the bracket 140.
[0038] The electrical box 170 contains a frequency converter and electrical components. The electrical box 170 controls the operation of the thin tobacco shred loosening device 100. For example, the frequency converter changes the vibration frequency of the screening mechanism and controls the rotational speeds of the first needle roller 121, second needle roller 122, third needle roller 131, and fourth needle roller 132, thereby adjusting the degree of tobacco shred loosening. By arranging the support frame 142 and the first receiving space 141 along the length y-direction of the support 140, the space at the bottom of the support 140 can be fully utilized.
[0039] In one embodiment, such as Figure 3 and Figure 4 As shown, the first loosening mechanism 120 includes a hopper 125, a first support plate 126, and a second support plate 127. One end of the hopper 125 has a first inlet 123 and a first outlet 124. The first inlet 123 is located above the first outlet 124 along the height z direction of the support 140. The two sides of the hopper 125 along the width y direction of the support 140 are connected to the support 140 through the first support plate 126 and the second support plate 127, respectively.
[0040] Furthermore, in one embodiment, the first loosening mechanism 120 further includes a plurality of support rods 128 disposed within the hopper 125 and positioned above the first needle roller 121 and the second needle roller 122 along the height direction z of the support 140. The two ends of each support rod 128 are respectively connected to the inner walls of the opposite sides of the hopper 125. The support rods 128 are used to support and fix the hopper 125, and also serve a protective function to prevent workers from being scratched by the first spring screw 1211 and the second spring screw 1221 when approaching the first needle roller 121 and the second needle roller 122 from the first feed inlet 123.
[0041] In one embodiment, the first loosening mechanism 120 further includes a detector 129, which is located above the first needle roller 121 and the second needle roller 122 along the height direction z of the support 140. The detector 129 includes a material level detection photoelectric sensor 1291 and a reflector 1292, which are respectively installed on the inner walls of the opposite sides of the hopper 125. The detector 129 has a blocked state and an unblocked state. The thin tobacco loosening device 100 is configured to stop in response to the unblocked state of the detector 129. It should be noted that the detector 129 is used to detect whether the thin tobacco flakes in the hopper 125 have reached the predetermined position. The working principle of the detector 129 is as follows: when the detector 129 is unobstructed, the level detection photoelectric sensor 1291 emits infrared light to the reflector 1292, and then the light is emitted back to the level detection photoelectric sensor 1291 via the reflector 1292; when the detector 129 is obstructed, the thin tobacco flakes in the hopper 125 reach a point where they can obstruct the level detection photoelectric sensor 1291 and the reflector 1292, forming an obstruction. By configuring the thin tobacco flake loosening device 100 to stop in response to the unobstructed state of the detector 129, the thin tobacco flake loosening device 100 can be prevented from running idle, thereby saving energy and improving the safety of the thin tobacco flake loosening device 100 during operation.
[0042] In one embodiment, along the height direction of the support 140, the hopper 125 includes an inlet section 1254, a guide section 1255, and a mating section 1256 connected sequentially from top to bottom; the inlet section 1254 and the guide section 1255 are arranged at an angle, and a first needle roller 121 and a second needle roller 122 are rotatably mounted on the mating section 1256. The inlet section 1254 and the guide section 1255 are used to guide the thin tobacco sheets into the mating section 1256 between the first needle roller 121 and the second needle roller 122. Optionally, in one embodiment, the angle formed between the inlet section 1254 and the guide section 1255 is an acute angle.
[0043] Specifically, the thin tobacco shred loosening device 100 also includes a first drive assembly 180 and a second drive assembly 190. The first drive assembly 180 includes a first motor 181, a coupling, a synchronous pulley 183, and a synchronous belt 184. The synchronous pulley 183 is fixedly mounted on the second support plate 127. The coupling is made of brass and serves to protect the first motor 181 in case of overload. The first motor 181 drives the first needle roller 121 to rotate via the coupling. The first needle roller 121 drives the second needle roller 122 to rotate synchronously in the opposite direction via the synchronous pulley 183 and the synchronous belt 184. The principle by which the second drive assembly 190 drives the third needle roller 131 and the fourth needle roller 132 to rotate in opposite directions is the same as that of the first drive assembly 180 and will not be repeated here.
[0044] In one embodiment, the ends of a plurality of first spring wire nails 1211 facing away from the first needle roller 121 form a first edge. The cross-sectional shape of the inner wall of one side of the mating section 1256 matches and is clearance-fitted with the shape of at least a portion of the opposite first edge. This prevents interference between the first spring wire nails 1211 and the side wall of the mating section 1256. Furthermore, the gap between the inner wall of one side of the mating section 1256 and the opposite at least a portion of the first edge is configured to be 1 mm, thus preventing the accumulation of thin tobacco sheets.
[0045] Multiple second spring wire staples 1221 form a second edge at one end opposite to the second needle roller 122. The cross-sectional shape of the inner wall of the other side of the mating section 1256 matches and gap-fits the shape of at least a portion of the opposite second edge. This prevents interference between the second spring wire staples 1221 and the side wall of the mating section 1256. Furthermore, the gap between the inner wall of the other side of the mating section 1256 and the opposite at least a portion of the second edge is configured to be 1 mm, thus preventing the accumulation of thin tobacco sheets.
[0046] In one embodiment, such as Figure 5 As shown, the screening mechanism 110 also includes a vibration motor 114, an eccentric wheel 115, and a connecting rod 116. The vibration motor 114 is mounted on the bracket 140. One end of the connecting rod 116 is radially connected to the eccentric wheel 115 along the eccentric wheel 115, and the other end is connected to the frame 111. The vibration motor 114 drives the eccentric wheel 115 to rotate, thereby causing the frame 111 and the screen 112 to vibrate together.
[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0048] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
