Description

Technical Field

[0001] The utility model relates to an anti - pricking type tobacco clip for tobacco braiding, belonging to the technical field of flue - cured tobacco equipment. Background Technique

[0002] The tobacco clip of the tobacco braider is mainly a comb - type tobacco clip, which mainly uses steel needles to insert and fix tobacco leaves. When in use, first place the tobacco leaves on the steel needles of the comb - type tobacco clip; then the steel needles will insert into the tobacco stalks to fix the tobacco leaves. After baking is completed, it is necessary to manually remove the dry tobacco leaves fixed on the steel needles. When the tobacco clip fixes the tobacco leaves, it should be noted that the process of unloading tobacco is relatively time - consuming and laborious, and may cause damage to the dry tobacco leaves. And due to the design of all steel needles, special attention should be paid to safety during use.

[0003] The above - mentioned comb - type tobacco clip can refer to a tobacco braiding clip for facilitating tobacco loading disclosed in the utility model patent with the authorization announcement number CN220529255U. This tobacco clip includes a tobacco clip main body, and a roller mechanism for facilitating tobacco loading is provided at the bottom of the tobacco clip main body. Hanging tobacco mechanisms that cooperate with the roller mechanism are symmetrically provided on the left and right side walls in the flue - cured tobacco barn. The tobacco clip main body is movably connected to the hanging tobacco mechanism through the roller mechanism; this tobacco clip improves the traditional tobacco - placing rack in the flue - cured tobacco barn and the tobacco clip for placing tobacco. It improves the traditional straight - rod type tobacco - placing rack into a guide - rail type chute that is convenient for tobacco loading and the tobacco clip to be pushed in, and a corresponding roller mechanism is installed at the bottom of the tobacco clip, which can effectively reduce the friction coefficient between the two, facilitate tobacco loading, and there is no need to frequently adjust the tobacco clip during tobacco loading. Even when the adjustment range of the tobacco clip is large, it will not cause it to fall off, and it is very convenient to use.

[0004] The above - mentioned tobacco clip facilitates the processing in the flue - cured tobacco barn. However, before fixing the tobacco leaves, the existence of numerous steel needles still poses a certain safety hazard to the operators. Whether moving the tobacco clip or placing the tobacco leaves on the steel needles, there is a risk of being pricked, which makes the operators have to wear relatively thick protective gloves, resulting in poor controllability and reduced processing efficiency. Content of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide an anti - pricking type tobacco clip for tobacco braiding to at least solve the problems such as poor timeliness and large management and control difficulty brought by manual inspection in the background technique.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only partial embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0028] It should be noted that the main concept of the present utility model is to add a protective shell 4 to the existing comb-type tobacco clip. The existing comb-type tobacco clip includes an upper pressing strip 1 and a lower pressing strip 2 that are mutually pressed to thread tobacco leaves. A number of steel needles 3 for passing through the tobacco leaves are provided on the bottom surface of the upper pressing strip 1 along its length direction. When making tobacco braids, the upper pressing strip 1 and the lower pressing strip 2 can be connected by means of snap connection, hinge connection, bolt connection, etc. Adding the protective shell 4 can block the steel needles 3 when the upper pressing strip 1 is not in use, preventing the staff from being accidentally pricked by the steel needles 3. When the upper pressing strip 1 is in use, the protective shell 4 moves upward to expose the steel needles 3, which does not affect the normal use of the steel needles 3, greatly reducing the risk of harm to the operator. The operator no longer needs to wear thick protective gloves, and the operability is better; this solves the technical problem in the prior art that the tobacco clip is prone to cause pricks, resulting in the operator needing to wear thick protective gloves, which causes poor operability.

[0029] After introducing the basic principle of the present utility model, the following specifically introduces various non-limiting embodiments of the present utility model. Any number of elements in the drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning.

[0030] The following refers to several representative embodiments of the present utility model to elaborate in detail the principle and spirit of the present utility model.

[0031] Embodiment 1 of the anti-prick tobacco clip for making tobacco braids provided by the present utility model:

[0032] As Figure 1 shown, an anti-prick tobacco clip for making tobacco braids includes a protective shell 4 sleeved outside the steel needles 3. The protective shell 4 has a shielding state of blocking the steel needles 3 when the upper pressing strip 1 is not in use, and a working state of moving upward when the upper pressing strip 1 is in use to expose the steel needles 3 to pass through the tobacco leaves.

[0033] The protective shell 4 is connected to the upper pressing strip 1 through an elastic member. When the upper pressing strip 1 is not in use, under the action of the elastic member, the protective shell 4 can block the steel needles 3. When the upper pressing strip 1 is pressed down for use, the protective shell 4 moves upward to expose the steel needles 3 to pass through the tobacco leaves. In this embodiment, the elastic member is a return spring 5. Multiple elastic members are arranged on the top surface of the upper pressing strip 1, and the protective shell 4 is fixedly connected to the upper pressing strip 1 through the elastic members.

[0034] Regarding the protective shell 4, the protective shell 4 has a placement groove for placing the steel needles 3, so that the steel needles 3 are placed in the placement groove when the upper pressing strip 1 is not in use, and move out of the placement groove to expose the steel needles 3 to pass through the tobacco leaves when the upper pressing strip 1 is in use. Preferably, the protective shell 4 can be an n-shaped structure, and the length of the n-shaped structure is not less than the arrangement length of the steel needles 3. The steel needles 3 are sleeved in the placement groove of the n-shaped structure.

[0035] In this embodiment, the protective shell 4 can be directly sleeved outside the upper pressing strip 1 and the steel needles 3. The inner top surface of the protective shell 4 is fixedly connected to the upper pressing strip 1 through an elastic member. This structure does not change the original structure of the upper pressing strip and has low manufacturing cost.

[0036] In this embodiment, for more convenient operation, a handrail 6 is further provided in the middle of the top surface of the upper pressing strip 1. The protective shell 4 is provided in two symmetrical parts on both sides of the handrail 6. In this structure, only the steel needles 3 in the middle of the bottom surface of the upper pressing strip 1 are left, greatly reducing the risk of harm to the operator. The operator no longer needs to wear thick protective gloves.

[0037] Embodiment 2 of the anti-pricking cigarette clip for cigarette braiding provided by the present utility model:

[0038] As Figure 2 shown, on the basis of Embodiment 1, the protective shell 4 can also be provided as one piece, and an avoidance groove 8 for the handrail 6 to pass through is provided in the middle of the protective shell 4. This structure can make all the steel needles 3 located inside the protective shell 4, and the use safety is higher.

[0039] Embodiment 3 of the anti-pricking cigarette clip for cigarette braiding provided by the present utility model:

[0040] As Figures 3 - 4 shown, on the basis of Embodiments 1 and 2, a moving groove 7 is opened on the upper pressing strip 1 along its length direction. The moving grooves 7 are symmetrically arranged in two on both sides of the steel needles 3. The protective shell 4 is inserted into the moving groove 7, and the inner top surface of the protective shell 4 is fixedly connected to the upper pressing strip 1 through an elastic member. This structure enables the protective shell 4 to move along the moving groove 7, and under the guiding action of the moving groove 7, the moving stability is good.

[0041] Embodiment 4 of the anti-pricking cigarette clip for cigarette braiding provided by the present utility model:

[0042] As Figures 1 - 4 shown, on the basis of Embodiments 1, 2, and 3, in order to improve safety, baffles 9 are further provided at both ends of the protective shell 4, and a fastener for vertically blocking the baffles 9 is provided on the lower pressing strip 2. This fastener is used to prevent the protective shell 4 from being lifted upward by external force after the baffles 9 are connected, further improving the use safety. The baffle 9 can be in the structure of a rectangular clamping plate, an L-shaped clamping plate, etc. The fastener includes a U-shaped hook 10, and the U-shaped hook 10 can be hinged to the lower pressing strip 2 through a tension spring 11. The tension spring 11 enables the U-shaped hook 10 to have a certain elastic telescopic margin, which is more convenient for installation and realizes elastic tension and blocking of the protective shell 4.

[0043] The working principle of the anti-pricking cigarette clip for cigarette braiding provided by the present utility model is as follows: When the whole cigarette clip is not in use, the protective shell 4 shields the steel needles 3. At the same time, the protective shell 4 can be moved and blocked through the cooperation of the baffle 9 and the fastener, avoiding accidental pricking of the staff by the steel needles 3. When performing cigarette braiding operation, the tobacco leaves are neatly placed on the lower pressing strip 2, and then the upper pressing strip 1 is aligned with the lower pressing strip 2 to remove the blocking structure of the protective shell 4. Then, hold the handrail and press the upper pressing strip 1 downward. During this process, the protective shell 4 moves upward, exposing the steel needles 3 to pass through the tobacco leaves, and thus the fixation of the tobacco leaves can be completed. Finally, the fastener can be connected to the baffle 9 to make the connection more reliable. In addition, after cigarette braiding is completed, the protective shell 4 can press the tobacco leaves tightly under the action of the return spring 5 and the fastener, preventing the tobacco leaves from falling off during handling and after shrinking during baking, and ensuring elastic clamping firmly.
