Description

Technical Field

[0001] This utility model relates to the field of tobacco clamp technology, and in particular to a fixing clamp for drying tobacco leaves with stems. Background Technology

[0002] In the initial processing of tobacco leaves, in order to achieve the required dryness for subsequent processing or to facilitate storage, the new tobacco leaves are usually clamped onto several tobacco clips that are spaced apart from the support rods. After all the new tobacco leaves are clamped onto the tobacco clips, the support rods are then horizontally placed in the curing barn. The hot air in the curing barn then bakes the new tobacco leaves clamped onto the tobacco clips through heat radiation, baking them to the required dryness for subsequent processing.

[0003] Although the above method of clamping new tobacco leaves onto several tobacco clips that are spaced apart from the support rods, and then baking the new tobacco leaves clamped onto the tobacco clips with hot air in the curing barn, can bake the new tobacco leaves to the dryness required for subsequent processing, there are still the following drawbacks in the process of clamping the new tobacco leaves onto the tobacco clips: Since different varieties of tobacco leaves require different spacing during drying, but the existing tobacco clips are fixedly connected to the support rods, the spacing between the existing tobacco clips cannot be adjusted in real time according to the spacing required for baking different varieties of tobacco leaves. It is necessary to remake tobacco clips with a spacing that matches the spacing required for baking different varieties of new tobacco leaves.

[0004] Therefore, it is necessary to improve and redesign the structure of the tobacco clamps that hold new tobacco leaves in order to solve the problem that the existing tobacco clamps are fixedly connected to the support rods, which makes it impossible to adjust the spacing between adjacent tobacco clamps in real time according to the spacing required for roasting different varieties of tobacco leaves. Utility Model Content

[0005] The purpose of this invention is to propose a fixing clamp for curing tobacco leaves with stems, so as to solve the problem that the existing tobacco clamps are fixedly connected to the support rod, which makes it impossible to adjust the spacing between adjacent tobacco clamps in real time according to the spacing required for curing different varieties of tobacco leaves.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A fixture for fixing tobacco leaves with stems during curing includes:

[0008] Sliding sleeve, the sliding sleeve is slidably mounted on the support rod;

[0009] The tension adjustable component and the sliding sleeve are slidably and adjustablely connected to the support rod through the tension adjustable component;

[0010] The cigarette clip and the sliding sleeve are connected to the cigarette clip via a connecting bracket.

[0011] Furthermore, the tensioning adjustable component is a locking screw, which is threadedly connected to the internal threaded through hole on the side wall of the sliding sleeve. One end of the locking screw located inside the sliding sleeve is in movable contact with the surface wall of the support rod, and the other end of the locking screw away from the sliding sleeve is connected to the handle.

[0012] Furthermore, at least two cigarette clips are provided on the connecting frame, with the two cigarette clips located on the side wall of the connecting frame respectively, and the cigarette clips on the two side walls of the connecting frame are arranged in opposite directions.

[0013] Furthermore, the connecting frame can be either a strip structure or a plate structure, with one end of the connecting frame connected to the bottom of the sliding sleeve, and the side wall of the connecting frame away from the sliding sleeve connected to the side walls of the two cigarette clips respectively.

[0014] Furthermore, the cigarette clip includes a first clamping arm, a second clamping arm, and a spring; the side wall of the second clamping arm is connected to the side wall of the connecting frame, and the second clamping arm is hinged to the first clamping arm via a connecting pin. The clamping end one of the first clamping arm passes through the clearance slot opened in the side wall of the second clamping arm, and the gripping end one of the first clamping arm and the gripping end two of the second clamping arm are connected by a spring. Both the gripping end one of the first clamping arm and the gripping end two of the second clamping arm are strip-shaped structures.

[0015] Furthermore, a tobacco stem clamping area is defined between the first and second tobacco stem clamping arms, and the sidewalls of the first and second tobacco stem clamping arms facing the tobacco stem clamping area are both toothed structures.

[0016] Furthermore, the cigarette clip also includes a clamping limiting post, which is disposed on the surface wall near the clamping end of the first cigarette clip arm. The clamping limiting post is in contact with and limited by the side walls of the clamping end of the second cigarette clip arm.

[0017] During the working process, when adjusting the spacing between different tobacco clips, first separate the tensioning adjuster from the support rod and the sliding sleeve, so that the sliding sleeve and the support rod are in a sliding state. Then, according to the spacing required for different varieties of tobacco leaves during baking, move the spacing between adjacent sliding sleeves along the support rod to a position that matches the spacing required for different varieties during baking. At the same time, the spacing between the tobacco clips connected to the adjacent sliding sleeves through the connecting frame is also moved to a position that matches the spacing required for different varieties during baking. Then, use the tensioning adjuster to lock the adjacent sliding sleeves that have been moved into place to the support rod, and lock the adjacent tobacco clips whose spacing has been adjusted to the correct position. At this point, clamp the tobacco leaves to be baked onto each tobacco clip with the adjusted spacing to meet the different spacing requirements required for different varieties of tobacco leaves during baking.

[0018] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0019] 1. This utility model solves the problem that existing tobacco clamps, which are fixedly connected to the support rod, cannot adjust the spacing between adjacent sliding sleeves according to the required spacing for different varieties of tobacco leaves before drying. The sliding sleeves are slidably mounted on the support rod, and the spacing between the tobacco clamps connected to the adjacent sliding sleeves via the connecting frame is also adjusted to match the required spacing for different varieties of tobacco leaves during drying. The adjustable tensioning device then locks the moved adjacent sliding sleeves to the support rod and locks the tobacco clamps with the adjusted spacing. Finally, the tobacco leaves to be dried are clamped onto each of the adjusted tobacco clamps. This solves the problem that existing tobacco clamps, which are fixedly connected to the support rod, cannot adjust the spacing between adjacent tobacco clamps in real time according to the required spacing for different varieties of tobacco leaves.

[0020] 2. This utility model features two tobacco clips positioned on opposite sides of a connecting frame. Because the clips are arranged in opposite directions, there is a certain distance between the tobacco leaves with stems held by one clip and those held by the other. This prevents the tobacco leaves from overlapping and affecting heating, thus improving both the roasting quality and the efficiency of the tobacco roasting process.

[0021] 3. By setting the side walls of the first and second clamping arms facing the tobacco stem clamping area as serrated structures, the first and second clamping arms can more stably clamp the tobacco stem in the tobacco leaves during the process of clamping the tobacco stem. This is because the serrated walls of the first and second clamping arms can increase the clamping contact area with the tobacco stem of the tobacco leaf.

[0022] 4. This utility model, by setting the clamping limiting post on the surface wall near the clamping end one of the first tobacco clamping arm, and having the clamping limiting post in contact with the side wall of the clamping end two of the second tobacco clamping arm, enables the side wall of the clamping end two of the second tobacco clamping arm to contact and limit the movement of the clamping limiting post during the process of the first and second tobacco clamping arms clamping the tobacco leaves with stems. This further prevents the clamping end one of the first tobacco clamping arm from continuing to move out of the clearance groove opened in the side wall of the second tobacco clamping arm, so that the first and second tobacco clamping arms will not over-clamp the tobacco stem and avoid the situation where the first and second tobacco clamping arms break the tobacco stem in the tobacco leaves with stems.

Detailed Implementation

[0028] like Figure 1-4 As shown, to make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] Example

[0030] The existing method involves clamping new tobacco leaves onto several tobacco clips that are spaced apart from support rods, and then baking the new tobacco leaves clamped onto the tobacco clips with hot air in the curing barn. This method can bake the new tobacco leaves to the dryness required for subsequent processing. However, there are still the following drawbacks in the process of clamping the new tobacco leaves onto the tobacco clips: Since different varieties of tobacco leaves require different spacing during drying, but the existing tobacco clips are fixedly connected to the support rods, the spacing between the existing tobacco clips cannot be adjusted in real time according to the spacing required for baking different varieties of tobacco leaves. It is necessary to remake the tobacco clips with a spacing that matches the spacing required for baking different varieties of new tobacco leaves.

[0031] Therefore, this application proposes a fixing clamp for curing tobacco leaves with stems, in order to solve the problem that the existing tobacco clamps are fixedly connected to the support rod, which makes it impossible to adjust the spacing between adjacent tobacco clamps in real time according to the spacing required for curing different varieties of tobacco leaves.

[0032] For details, please refer to Figure 1 The fixture for drying tobacco leaves with stems includes a support rod 1, a sliding sleeve 2, a tension adjustable component 3, and a tobacco clamp 4. The sliding sleeve 2 is slidably sleeved on the support rod 1. The sliding sleeve 2 is slidably and adjustablely connected to the support rod 1 through the tension adjustable component 3. The sliding sleeve 2 is connected to the tobacco clamp 4 through a connecting frame 5.

[0033] In practical applications, when adjusting the spacing between different tobacco clips, first separate the tensioning adjustable piece 3 from the support rod 1 and the sliding sleeve 2, so that the sliding sleeve 2 and the support rod 1 are in a sliding state. Then, according to the spacing required for different varieties of tobacco leaves during baking, move the spacing of the adjacent sliding sleeves 2 along the support rod 1 to a position that matches the spacing required for different varieties during baking. At the same time, the spacing between the tobacco clips connected to the adjacent sliding sleeves 2 through the connecting frame 5 is also moved to a position that matches the spacing required for different varieties during baking. Then, use the tensioning adjustable piece 3 to lock the adjacent sliding sleeves that have been moved to the position to the support rod, and lock the adjacent tobacco clips whose spacing has been adjusted to the position. At this time, clamp the tobacco leaves to be baked onto each tobacco clip 4 with the adjusted spacing to meet the different spacing requirements required for different varieties of tobacco leaves during baking. This solves the problem that the existing tobacco clips are fixedly connected to the support rod, which prevents the spacing between adjacent tobacco clips from being adjusted in real time according to the spacing required for baking different varieties of tobacco leaves.

[0034] Please see Figure 2 The tension adjustable component 3 used to achieve the sliding adjustable connection between the sliding sleeve 2 and the support rod 1 is a locking screw. The locking screw is threadedly connected to the internal threaded through hole 6 on the side wall of the sliding sleeve 2. One end of the locking screw located inside the sliding sleeve 2 is in movable contact with the surface wall of the support rod 2 inside the sliding sleeve 2, and the other end of the locking screw away from the sliding sleeve 2 is connected to the handle 7.

[0035] In practical applications, when adjusting the position of the sliding sleeve 2 on the support rod 1, the handle 7 connected to one end of the locking screw can be turned so that the thread of the locking screw, which is threaded to the sliding sleeve 2, does not collide with the support rod 1, that is, the sliding sleeve 2 and the support rod 1 are slidably connected. Then, the sliding sleeve 2 is moved along the support rod 1 to the corresponding position to complete the process of adjusting the position of the sliding sleeve 2 along the support rod 1.

[0036] When locking the moved-in sliding sleeve 2 and support rod 1 with the locking screw, the pre-removed locking screw can be threaded into the internal threaded through hole 6 on the side wall of the sliding sleeve 2. Then, turn the handle 7 connected to one end of the locking screw so that one end of the locking screw abuts against the surface wall of the support rod 1 inside the sliding sleeve 2 to lock the moved-in sliding sleeve 2 and support rod 1.

[0037] Please see Figure 2 At least two tobacco clips 4 are provided on the connecting frame 5 for holding the tobacco stems in the tobacco leaves with stems. The two tobacco clips 4 are located on the side wall of the connecting frame 5 respectively, and the tobacco clips 4 on the two side walls of the connecting frame 5 are arranged in opposite directions.

[0038] In practical applications, when using tobacco clips to hold the tobacco stems in tobacco leaves with stems, some of the tobacco leaves with stems can be held on the tobacco clips 4 on one side wall of the connecting frame 5, while the other part of the tobacco leaves with stems can be held on the tobacco clips 4 on the other side wall of the connecting frame 5. Since the tobacco clips 4 on the two side walls of the connecting frame 5 are arranged in opposite directions, that is, there is a certain distance between the tobacco leaves with stems held by one tobacco clip 4 and the tobacco leaves with stems held by the other tobacco clip 4, the tobacco leaves with stems held by the two tobacco clips 4 will not cover each other and affect the heating. This not only improves the roasting quality of the tobacco leaves with stems held by the two tobacco clips 4, but also improves the efficiency of tobacco roasting.

[0039] Please see Figure 2 The connecting frame 5 used to connect with the sliding sleeve 2 and the cigarette clip 4 can be either a strip-shaped structure or a plate-shaped structure, such as a strip-shaped connecting strip or a plate-shaped connecting strip. One end of the connecting frame 5 is connected to the bottom of the sliding sleeve 2, and the side wall of the connecting frame 5 at the end away from the sliding sleeve 2 is connected to the side wall of the two cigarette clips 4 respectively.

[0040] In practical applications, when the sliding sleeve 2 and the cigarette clip 4 are connected to the connecting frame 5, one end of the plate-shaped connecting frame 5 can be welded to the outer wall of the sliding sleeve 2, and the side wall of the connecting frame 5 at the end away from the sliding sleeve 2 can be welded to or detachably connected to the two cigarette clips 4.

[0041] Please refer to 3. The tobacco clamp 4 for holding the tobacco stems in the tobacco leaves includes a first clamping arm 8, a second clamping arm 9, a connecting pin 18, and a spring 10. The connecting pin 18 is used to form a hinge between the first clamping arm 8 and the second clamping arm 9 so that the first clamping arm 8 and the second clamping arm 9 can be closed or opened. The spring 10 is used to form a certain tension clamping degree between the first clamping arm 8 and the second clamping arm 9.

[0042] Specifically, the sidewalls of the second cigarette clamping arm 9 are connected to the sidewalls of the connecting frame 5. The middle part of the second cigarette clamping arm 9 is hinged to the middle part of the first cigarette clamping arm 8 through the connecting pin 18. The clamping end 11 of the first cigarette clamping arm 8 passes through the clearance slot 12 opened in the sidewall of the second cigarette clamping arm 9. The gripping end 13 of the first cigarette clamping arm 8 and the gripping end 14 of the second cigarette clamping arm 9 are connected by a spring 10. Both the gripping end 13 of the first cigarette clamping arm 8 and the gripping end 14 of the second cigarette clamping arm 9 are strip-shaped structures.

[0043] In practical application, when the cigarette clip holds a tobacco leaf with stem, first hold the first holding end 13 of the first cigarette clip arm 8 and the second holding end 14 of the second cigarette clip arm 9 and press them inward. The spring 11 between the first holding end 13 of the first cigarette clip arm 8 and the second holding end 14 of the second cigarette clip arm 9 will be in a compressed state. When the spring 11 is compressed, the first holding end 11 of the first cigarette clip arm and the second holding end 17 of the second cigarette clip arm will be in an open state. At this time, first place the tobacco stem part of the tobacco leaf with stem onto the first holding end 13 of the first cigarette clip arm 8. The opening area between the first clamping arm 8 and the second clamping arm 9 with the clamping end 17 is then slowly released. Under the elastic force of the torsion spring returning to its original length, the clamping end 11 of the first clamping arm 8 and the clamping end 17 of the second clamping arm 9 close, clamping the tobacco stem in the tobacco leaf with stem that has been placed between the clamping end 11 of the first clamping arm 8 and the clamping end 17 of the second clamping arm 9, thus completing the process of clamping the tobacco leaf with stem with the tobacco tongs.

[0044] It should be noted that the middle part of the second clamping arm 9 is hinged to the middle part of the first clamping arm 8 through the connecting pin 18. Specifically, part of the first clamping arm 8 is located in the clearance groove 12 opened in the side wall of the second clamping arm 9, and part of the first clamping arm 8 is rotatably connected to the inner groove arm of the clearance groove 12 opened in the side wall of the second clamping arm 9. The second clamping arm 9 is hinged to part of the first clamping arm 8 in the clearance groove 12 through the connecting pin 18.

[0045] Please see Figure 4 In order to more stably clamp the tobacco leaves with stems, the sidewalls of the first clamping arm 8 and the second clamping arm 9 facing the tobacco stem clamping area 15 are both set with a serrated structure. The tobacco stem clamping area 15 is defined between the first clamping arm 8 and the second clamping arm 9.

[0046] In practical applications, during the process of clamping tobacco leaves with stems by the first clamping arm 8 and the second clamping arm 9, since the side walls of the first clamping arm 8 and the second clamping arm 9 facing the tobacco stem clamping area 15 are both set as serrated structures, the serrated walls of the first clamping arm 8 and the second clamping arm 9 can increase the clamping contact area with the tobacco stem, and the first clamping arm 8 and the second clamping arm 9 can clamp the tobacco leaves with stems more stably.

[0047] It should be noted that the individual serrations in the serrated structure are not very sharp, so they will not easily break the tobacco stems in the tobacco leaves with stems.

[0048] Please see Figure 4To prevent the first and second clamping arms 8 and 9 from breaking the tobacco stems in the tobacco leaves with stems, a fixing clamp for drying tobacco leaves with stems also includes a clamping limiting post 16. The clamping limiting post 16 is disposed on the surface wall near the clamping end 11 of the first clamping arm, and the clamping limiting post 16 is in contact with and limited by the side wall of the clamping end 17 of the second clamping arm.

[0049] In practical application, during the process of the first clamping arm 8 and the second clamping arm 9 clamping the tobacco leaves with stems, since there is a clamping limiting post 16 connected to the surface wall of the clamping end 11 near the first clamping arm 8, the side wall of the clamping end 17 of the second clamping arm will abut against the clamping limiting post 16, further preventing the first clamping arm 8 from continuing to move through the clearance groove 12 opened on the inner side wall of the second clamping arm 9, so that the first clamping arm 8 and the second clamping arm 9 will not excessively clamp the tobacco stems in the tobacco leaves with stems, thereby avoiding the situation where the first clamping arm 8 and the second clamping arm 9 break the tobacco leaves with stems.

[0050] Although the present invention has been described herein with reference to several 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 the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
