Description

Technical Field

[0001] This application relates to the field of heating and humidifying machines, and in particular to a heating and humidifying machine for tobacco. Background Technology

[0002] The tobacco shred heating and humidifying machine is mainly used to regulate the temperature and humidity of tobacco shreds to improve their softness and plasticity, and to prevent them from breaking during the cigarette manufacturing process. During operation, the tobacco shreds are vibrated and conveyed by a vibrating trough that reciprocates between the inlet and outlet. To ensure the vibrating trough remains closed throughout this process, the machine's door is typically secured.

[0003] However, due to the high oscillation frequency of the vibration groove in the existing door cover fixing structure, the rotating shaft in the door cover fixing structure will collide with its main body. The main body will be damaged or broken due to long-term impact, thus affecting the overall service life of the tobacco heating and humidifying machine. Utility Model Content

[0004] Therefore, it is necessary to provide a tobacco heating and humidifying machine with a stable connection structure that can reduce structural damage or breakage due to impact and extend the service life of the whole machine.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A tobacco heating and humidifying machine includes a frame, a vibrating body, and a door cover. The vibrating body is mounted on the frame and has an open vibrating groove for accommodating tobacco. The door cover is disposed on the open groove and is rotatably connected to the vibrating body via a rotating shaft, so that the door cover can open and close the open groove.

[0007] The tobacco heating and humidifying machine also includes a connecting sleeve and a top rod. The connecting sleeve is connected to the vibrating body and a positioning hole is provided on the outer peripheral wall of the connecting sleeve. The top rod is connected to the connecting sleeve, and one end of the top rod passes through the positioning hole and abuts against the rotating shaft.

[0008] The axis of the positioning hole is set at an angle to the axis of the rotating shaft.

[0009] Understandably, this application uses a connecting sleeve and a top rod to fix the connecting sleeve to the vibrating body. One end of the top rod passes through the positioning hole of the connecting sleeve and abuts against the rotating shaft. In this way, the rotating shaft and the connecting sleeve are fixedly connected. By setting the axis of the positioning hole at an angle to the axis of the rotating shaft, the rotating shaft can be fixed to the vibrating body. This prevents the rotating shaft from being unstable and impacting the vibrating body when the vibrating body is reciprocating, thus avoiding damage to the vibrating body. In other words, by restricting the axis of the positioning hole and the axis of the rotating shaft, the top rod can stably connect the rotating shaft and the vibrating body, avoiding the situation of loose connection and impact damage, thereby extending the service life of the tobacco heating and humidifying machine.

[0010] In one embodiment, the rotating shaft is provided with a mating hole, and one end of the push rod that passes through the positioning hole extends into the mating hole.

[0011] Understandably, the end of the push rod that passes through the positioning hole extends into the mating hole, further increasing the stability of the connection between the rotating shaft and the vibrating body, and preventing them from colliding and being damaged due to unstable fixing.

[0012] In one embodiment, the end of the top rod that passes through the positioning hole is configured as a cone, and the mating hole is configured as a tapered hole, wherein the cone can be adapted to and fit the tapered hole.

[0013] In one embodiment, the top rod is detachably connected to the connecting sleeve.

[0014] Understandably, the detachable connection makes it easy to replace the top rod and shaft, saving on the later maintenance costs of the tobacco heating and humidifying machine.

[0015] In one embodiment, the positioning hole is configured as a threaded hole, and the push rod is threadedly connected to the threaded hole.

[0016] Understandably, threaded connections are more stable than direct insertion and abutment connection, preventing the push rod from coming out of the positioning hole and causing the shaft to fail to be fixed. In other words, the threaded connection ensures a stable connection between the push rod and the shaft and the vibrator.

[0017] In one embodiment, the peripheral wall thickness of the connecting sleeve is T, where 25mm ≤ T ≤ 35mm.

[0018] Understandably, the setting of 25mm≤T≤35mm ensures that when the shaft reciprocates with the vibrator, the connecting sleeve has sufficient strength to support the force of the push rod pressing the connecting sleeve, preventing the connecting sleeve from breaking due to insufficient structural strength. It also increases the contact area between the push rod and the connecting sleeve, allowing the push rod to better limit the shaft to the vibrator through the connecting sleeve. At the same time, it avoids the peripheral wall of the connecting sleeve being too thick, ensuring that its model can be adapted to the vibrator.

[0019] In one embodiment, a connecting seat is provided on the outer wall of the vibrator, and a connecting groove is provided on the connecting seat. First connecting holes are provided on the opposite side walls of the connecting groove. A connecting arm is provided on the door cover. A second connecting hole corresponding to the first connecting hole is provided at the end of the connecting arm away from the door cover. The end of the connecting arm away from the door cover is accommodated in the connecting groove. The rotating shaft passes through the first connecting hole and the second connecting hole.

[0020] One end of the rotating shaft is provided with a stepped surface, and along the axial direction of the rotating shaft, the stepped surface is limited and abuts against one of the side walls of the connecting groove where the first connecting hole is opened.

[0021] Understandably, by setting the stepped surface on the rotating shaft, the stepped surface abuts against the side wall of the first connecting hole of the connecting groove, further limiting the rotating shaft. This allows the rotating shaft to reciprocate with the connecting seat during the operation of the vibrator, avoiding the rotating shaft and the connecting seat moving inconsistently and impacting the connecting seat, which would damage the connecting seat. This further increases the stability of the connecting structure on the tobacco heating and humidifying machine and extends its service life.

[0022] In one embodiment, the pivot includes a first segment and a second segment, the second segment being connected to one end of the first segment and forming the stepped surface between the second and the first segment.

[0023] Understandably, the two-section design of the shaft can further limit the shaft to the connecting seat while ensuring the reliability of the shaft structure.

[0024] In one embodiment, the first segment has a circular cross-section, the second segment has a semi-circular cross-section, and the first connecting hole that mates with the second segment is a semi-circular hole.

[0025] In one embodiment, the tobacco heating and humidifying machine further includes a locking handle and a safety switch. The locking handle is installed on the vibrating body and can lock the door cover to the vibrating body. The safety switch is located on the locking handle and is used to detect the relative position information between the door cover and the vibrating body.

[0026] Understandably, the locking handle can lock the door cover onto the vibrator, ensuring that the door cover can move synchronously with the vibrator and preventing them from colliding due to unstable positioning, which could cause structural damage. At the same time, the protection switch can detect the connection status between the door cover and the vibrator in a timely manner to ensure that the door cover and the vibrator are in a locked state when the vibrator is working.

[0027] Compared with existing technologies, the tobacco heating and humidifying machine described above uses a connecting sleeve and a top rod to fix the connecting sleeve to the vibrating body. One end of the top rod passes through the positioning hole of the connecting sleeve and abuts against the rotating shaft. In this way, the rotating shaft and the connecting sleeve are fixedly connected. By setting the axis of the positioning hole at an angle to the axis of the rotating shaft, the rotating shaft can be fixed to the vibrating body. This avoids the rotating shaft from being unstable and impacting the vibrating body when the vibrating body is reciprocating, thus preventing damage to the vibrating body. In other words, by restricting the axis of the positioning hole and the axis of the rotating shaft, the top rod can stably connect the rotating shaft and the vibrating body, avoiding the situation of loose connection and impact damage, thereby extending the service life of the tobacco heating and humidifying machine.

[0042] Please see Figures 1 to 4 This application provides a tobacco heating and humidifying machine 100. By improving some of the structures in the tobacco heating and humidifying machine 100, the stability of the structural connection is improved, and the tobacco heating and humidifying machine 100 is prevented from colliding with each other due to the weak connection structure during operation, which would cause structural damage or even breakage and affect the service life of the whole machine.

[0043] Specifically, the tobacco heating and humidifying machine 100 includes a frame 101, a vibrating body 10, and a door cover 20. The vibrating body 10 is mounted on the frame 101 and has a vibrating groove 11 with an opening 111 for accommodating tobacco. The door cover 20 covers the opening 111 and is rotatably connected to the vibrating body 10 via a rotating shaft 50, so that the door cover 20 can open and close the opening 111. The tobacco heating and humidifying machine 100 also includes a connecting sleeve 30 and a top rod 40. The connecting sleeve 30 is connected to the vibrating body 10 and has a positioning hole 31 on its outer peripheral wall. The top rod 40 is connected to the connecting sleeve 30, and one end of the top rod 40 passes through the positioning hole 31 and abuts against the rotating shaft 50. The axis of the positioning hole 31 is set at an angle to the axis of the rotating shaft 50.

[0044] It should be explained that this application uses a connecting sleeve 30 and a top rod 40 to fix the connecting sleeve 30 to the vibrating body 10. One end of the top rod 40 passes through the positioning hole 31 of the connecting sleeve 30 and abuts against the rotating shaft 50. In this way, the rotating shaft 50 and the connecting sleeve 30 are fixedly connected. By setting the axis of the positioning hole 31 at an angle to the axis of the rotating shaft 50, the rotating shaft 50 can be fixed to the vibrating body 10. This avoids the rotating shaft 50 from being unstable and impacting the vibrating body 10 when the vibrating body 10 is reciprocating, which would cause damage to the vibrating body 10. That is, by restricting the axis of the positioning hole 31 and the axis of the rotating shaft 50, the top rod 40 can stably connect the rotating shaft 50 and the vibrating body 10, avoiding the situation of loose connection and impact damage, thereby extending the service life of the tobacco heating and humidifying machine 100.

[0045] Here, the connecting sleeve 30 and the top rod 40 are detachably connected. This facilitates the replacement of the top rod 40 and the rotating shaft 50, saving on the later maintenance costs of the tobacco heating and humidifying machine 100.

[0046] like Figure 1 and Figure 2As shown, a vibrating spring 12 is also provided inside the vibrating body 10. The vibrating spring 12 is located inside the vibrating groove 11 and is used to make the vibrating groove 11 vibrate.

[0047] Furthermore, the vibrating body 10 has an inlet 13 and an outlet 14. The tobacco enters the vibrating body 10 through the inlet 13, undergoes heating and humidification treatment, and is then conveyed to the outlet 14 via vibration by the vibrating body 10. For example... Figure 6 As shown, the thickness of the peripheral wall of the connecting sleeve 30 is T, where 25mm ≤ T ≤ 35mm. This ensures that when the rotating shaft 50 reciprocates with the vibrating body 10, the connecting sleeve 30 has sufficient strength to support the force exerted by the push rod 40 on it, preventing breakage due to insufficient structural strength. It also increases the contact area between the push rod 40 and the connecting sleeve 30, allowing the push rod 40 to better limit and connect the rotating shaft 50 to the vibrating body 10. Simultaneously, it avoids the peripheral wall of the connecting sleeve 30 being too thick, ensuring its compatibility with the vibrating body 10.

[0048] Here, the peripheral wall thickness T of the connecting sleeve 30 can be 25mm, 30mm, 35mm, etc. Of course, it is not limited to this; the specific value of the peripheral wall thickness T of the connecting sleeve 30 can be determined according to the actual situation. In this embodiment, the peripheral wall thickness T of the connecting sleeve 30 is 30mm.

[0049] Please continue to refer to this. Figure 3 and Figure 4 The angle between the axis of the positioning hole 31 and the axis of the rotating shaft 50 is set to 90°. Of course, this is not the only limitation; the actual angle between the axis of the positioning hole 31 and the axis of the rotating shaft 50 can be determined according to specific circumstances.

[0050] Furthermore, the positioning hole 31 is configured as a threaded hole, and the push rod 40 is threadedly connected to the threaded hole. It is understandable that the threaded connection is more stable than the direct insertion and abutment connection or snap-fit ​​method, which can prevent the push rod 40 from coming out of the positioning hole 31 and causing the rotating shaft 50 to fail to be fixed. That is, the threaded connection ensures the stable fixation of the rotating shaft 50 and the vibrator 10 by the push rod 40.

[0051] like Figures 4 to 6 As shown, the end of the push rod 40 that passes through the positioning hole 31 is configured as a cone 41, and the rotating shaft 50 is provided with a mating hole 51. The end of the push rod 40 that passes through the positioning hole 31 extends into the mating hole 51. In this way, the stability of the connection between the push rod 40 and the rotating shaft 50 and the vibrator 10 can be further improved, and the unstable fixing of the rotating shaft 50 and the vibrator 10 can be avoided, so that the rotating shaft 50 will hit the connecting sleeve 30 when the vibrator 10 is in operation, causing structural damage.

[0052] Furthermore, the mating hole 51 is configured as a tapered hole, and the cone 41 can be adapted to and fit the tapered hole.

[0053] like Figures 1 to 6 As shown, one end of the rotating shaft 50 is provided with a stepped surface 52, and a connecting seat 60 is provided on the outer wall of the vibrating body 10. A connecting groove 61 is provided on the connecting seat 60, and a first connecting hole 62 is provided on each of the opposite side walls of the connecting groove 61. A connecting arm 70 is provided on the door cover 20. A second connecting hole 71 corresponding to the first connecting hole 62 is provided at the end of the connecting arm 70 away from the door cover 20. The end of the connecting arm 70 away from the door cover 20 is accommodated in the connecting groove 61. The rotating shaft 50 passes through the first connecting hole 62 and the second connecting hole 71. Along the axial direction of the rotating shaft 50, the stepped surface 52 and one of the side walls of the connecting groove 61 with the first connecting hole 62 are limited and abutted. It is understandable that by setting the stepped surface 52 on the rotating shaft 50, the stepped surface 52 is limited and abuts against the side wall of the first connecting hole 62 of the connecting groove 61, further limiting the rotating shaft 50. During the vibration of the vibrator 10, the rotating shaft 50 can reciprocate together with the connecting seat 60, avoiding the rotating shaft 50 and the connecting seat 60 from moving inconsistently and hitting the connecting seat 60, which would cause damage to the connecting seat 60. This further increases the stability of the connecting structure on the tobacco heating and humidifying machine 100 and extends its service life.

[0054] It should be explained that the connecting seat 60 and the connecting sleeve 30 are designed as an integral structure, with the connecting sleeve 30 located on the outer wall of the connecting seat 60. The end of the rotating shaft 50 near the stepped surface 52 extends through the connecting sleeve 30 into the first connecting hole 62 and the second connecting hole to connect the connecting seat 60 and the connecting arm 70. Thus, the connection between the top rod 40 and the connecting sleeve 30, combined with the design of the stepped surface 52, makes the connection between the connecting seat 60 and the connecting arm 70 more stable. This prevents the rotating shaft 50, the connecting arm 70, and the connecting seat 60 from colliding and colliding with each other for extended periods due to asynchronous vibration, thereby extending the service life of the tobacco heating and humidifying machine 100.

[0055] In one embodiment, multiple connecting seats 60 are provided, spaced apart along the length of the tobacco heating and humidifying machine 100, and the top rod 40 corresponds to each connecting seat 60. In this way, the multiple connecting seats 60 and the top rod 40 can be used to limit and support the vibrator 10 and the door cover 20, further improving the stability of the structural connection of the tobacco heating and humidifying machine 100.

[0056] Here, the connecting base 60 can be set to two, three, or five, or more. Of course, it is not limited to this; the specific number of connecting bases 60 can be determined according to the actual situation. In this embodiment, two connecting bases 60 are set.

[0057] like Figure 5As shown, the rotating shaft 50 includes a first segment 53 and a second segment 54. The second segment 54 is connected to one end of the first segment 53 and forms a stepped surface 52 between the second segment 54 and the first segment 53. It can be understood that the two-segment design of the rotating shaft 50 can ensure the structural strength of the rotating shaft 50 and, while further limiting the rotating shaft 50 to the connecting seat 60, ensure the structural reliability of the rotating shaft 50.

[0058] Specifically, the cross-section of the first segment 53 is circular, the cross-section of the second segment 54 is semi-circular, and the first connecting hole 62 that mates with the second segment 54 is a semi-circular hole.

[0059] Please continue to refer to this. Figure 2 The tobacco heating and humidifying machine 100 also includes a locking handle 80 and a protection switch (not shown). The locking handle 80 is installed on the vibrating body 10 and can lock the door cover 20 to the vibrating body 10. The protection switch is located on the locking handle 80 and is used to detect the relative position information between the door cover 20 and the vibrating body 10. In this way, the locking handle 80 can lock the door cover 20 to the vibrating body 10, ensuring that the door cover 20 can move synchronously with the vibrating body 10, avoiding structural damage caused by collision due to unstable positioning. At the same time, the protection switch can detect the connection status between the door cover 20 and the vibrating body 10 in a timely manner. When the protection switch detects that the door cover 20 has moved relative to the vibrating body 10, it can sound an alarm and control the tobacco heating and humidifying machine 100 to stop, avoiding quality problems such as material interruption.

[0060] 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.

[0061] 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.
