Description

Technical Field

[0001] The utility model relates to the technical field of tobacco slice conveying, in particular to a material leakage prevention device arranged between the output end of a belt and the feed end of a slicer. Background Art

[0002] The feed end of the slicer is widely used in tobacco slicing processing equipment. The leakage between the swing arm and the belt and the belt scratching problem at the feed end of the slicer are common problems. It will affect the product quality, cause the slicer belt performance to decline, shorten the belt life, and even cause the belt to break, affecting production.

[0003] Generally speaking, when setting up a slicer, technicians will leave an appropriate gap between the output end of the belt conveyor and the feed end of the slicer to prevent the belt from contacting the feed end of the slicer and causing prolonged friction between the belt and the feed end of the slicer during movement, causing the belt to wear and break. At the same time, the friction between the feed end of the slicer and the belt will increase the load on the belt drive motor, causing the performance of the belt drive motor to decline, and even causing abnormal noises in the equipment, wear of the drive shaft, etc.

[0004] However, although reserving an appropriate gap can effectively protect the belt, the gap at the output end of the belt will cause the tobacco sheets to fall when being transported through the gap, resulting in leakage; in addition, some of the tobacco sheets stuck in the gap will accumulate at the output end of the belt, further causing related problems such as slow belt rotation, poor efficiency of the slicer, and blockage causing extrusion and deformation of the equipment. Utility Model Content

[0005] The utility model provides a leakage prevention device arranged between the output end of a belt and the feed end of a slicer, by arranging a rotatable gap roller between the output end of the belt and the feed end of the slicer, and by arranging an anti-blocking strip between the gap roller and the feed end of the slicer, and by making the gap roller close to the belt, so as to achieve seamless connection between the output end of the belt and the feed end of the slicer, so as to effectively prevent tobacco sheets from falling and being blocked, so as to solve the above technical problems.

[0006] The utility model solves the above-mentioned problem by means of the following technical solutions: providing a leakage prevention device arranged between the output end of a belt and the feed end of a slicer, comprising a gap roller and a mounting bracket, both ends of the gap roller being rotatably arranged on the mounting bracket, and the gap roller being close to the belt; and also comprising an anti-blocking strip arranged on the mounting bracket and located between the feed end of the slicer and the gap roller, the anti-blocking strip being close to the side wall of the feed end of the slicer, and a flexible contact layer extending to the surface of the gap roller being further arranged on the surface of the anti-blocking strip facing the gap roller.

[0007] Furthermore, the flexible contact layer is a plurality of flexible bristles extending and abutting against the surface of the gap roller.

[0008] Furthermore, it also includes a transmission mechanism arranged between the gap roller and the pulley at the output end of the belt, and the gap roller rotates synchronously with the pulley through the transmission mechanism.

[0009] Furthermore, the rotation direction of the gap roller is the same as the rotation direction of the pulley.

[0010] Furthermore, the transmission mechanism includes a driven gear sleeved and fixed at the end of the gap roller, a driving gear sleeved and installed at the installation shaft end of the pulley, and an intermediate gear, and the driving gear, the intermediate gear, and the driven gear are meshed and connected in sequence.

[0011] Furthermore, the mounting bracket is also provided with a horizontal bracket extending in the direction of the driving gear, and the intermediate gear is correspondingly mounted on the horizontal bracket and is meshedly connected with the driving gear and the driven gear at the same time.

[0012] Furthermore, it also includes a drive control component for driving the gap roller to move into or out of the area between the output end of the belt and the feed end of the slicer.

[0013] Furthermore, the drive control component includes a swing motor installed on the slicer, and the output rotating shaft of the swing motor is fixedly connected to the mounting bracket; the swing motor runs to drive the mounting bracket to swing, thereby causing the gap roller to rotate correspondingly around the output rotating shaft of the swing motor to move into or out of the area between the output end of the belt and the feed end of the slicer.

[0014] Beneficial effects of the utility model:

[0015] The utility model discloses a leakage prevention device which is arranged between the output end of a belt and the feed end of a slicer. By arranging a gap roller at the gap between the output end of the belt and the feed end of the slicer, by making no gap between the gap roller and a belt pulley, and arranging an anti-blocking strip between the gap roller and the feed end of the slicer, the rotation of the gap roller is not affected, so as to effectively prevent tobacco sheets from being leaked and to make the gap roller and the belt pulley at the output end of the belt rotate in the same direction, so that the tobacco sheets can pass through the gap roller quickly, and the tobacco sheets can be effectively prevented from falling when being transported into the sheet machine.

[0021] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0022] See also Figure 1 and Figure 2The specific embodiment of the utility model is a leakage prevention device arranged between the output end of the belt and the feed end of the slicer, comprising a gap roller 1 and a mounting bracket 2. The mounting bracket 2 is configured as a straight rod bracket structure in this embodiment. The two ends of the gap roller 1 are rotatably mounted at the upper end of a mounting bracket 2, and the lower ends of the two mounting brackets 2 are both arranged at the swing output end of the drive control component. In this regard, when the leakage prevention device of this embodiment is actually working, the drive control component will work to control the two mounting brackets 2 to swing synchronously, so as to drive the gap roller 1 to move to the side close to the output end of the belt, so that there is no gap between the gap roller 1 and the side of the output end of the belt. In addition, a horizontal bracket extends to the right side of the upper end of the mounting bracket 2, and the right end of the horizontal bracket extends upward to install an anti-blocking strip 3. The anti-blocking strip 3 is arranged along the axial direction of the gap roller 1 and is equivalent to the length of the gap roller 1. The anti-blocking strip 3 is also provided with a flexible contact layer 4 on the side facing the gap roller 1; when the anti-blocking strip 3 is fixedly installed on the upper right side of the horizontal bracket, the anti-blocking strip 3 also maintains a constant contact state with the gap roller 1 through the flexible contact layer 4. In this regard, when the leakage prevention device of this embodiment is working, the gap roller 1 will not only be tightly attached to the belt under the drive control component, but the anti-blocking strip 3 will also be tightly attached to the lower left edge of the feed port of the slicer under the drive control component, so as to further eliminate any gap between the gap roller 1 and the feed end of the slicer. Moreover, driven by the pulley on the output end of the belt, the gap roller 1 will also rotate synchronously to avoid friction between the belts.

[0023] In combination with the above content, it can be known that since there is no gap between the gap roller 1 and the output end of the belt and the feed end of the slicer, and the gap roller 1 can move with the belt, it can ultimately achieve a wear-free anti-leakage protection function.

[0024] Furthermore, in the present embodiment, the drive control component is configured as a conventional swing motor 7 with a dual output shaft, and the swing motor 7 is fixedly mounted on the body equipment of the conveying device corresponding to the belt or the body structure of the slicer. In addition, in the present embodiment, the swing motor 7 is configured as a motor type that can rotate in both directions. In addition, in the present embodiment, the technician can control the swing motor 7 to drive the mounting bracket 2 to swing rightward so that the gap roller 1 moves out from between the output end of the belt and the feed end of the slicer, so as to facilitate the maintenance of the gap roller 1; at the same time, the technician can also drive the gap roller 1 to move to the position between the output end of the belt and the feed end of the slicer through the swing motor 7 to normally implement the leakage prevention function.

[0025] Furthermore, in the present embodiment, the surface of the anti-blocking strip 3 facing the gap roller 1 is set as an arc surface that fits the surface of the gap roller 1, and the flexible contact layer 4 on the arc surface is configured as a plurality of flexible bristles extending and abutting the surface of the gap roller 1, so as to ensure that there is no leakage gap between the anti-blocking strip 3 and the gap roller 1, and enable the gap roller 1 to rotate smoothly.

[0026] Furthermore, in the present embodiment, in order to prevent the gap roller 1 and the pulley at the output end of the belt from rotating in opposite directions, causing the tobacco sheet to be rolled downward when passing between the two, a transmission mechanism layer 5 is further provided between the gap roller 1 and the pulley at the output end of the belt, and the transmission mechanism layer 5 comprises a driven gear 53 sleeved and fixed on the axial end of the gap roller 1, a driving gear 51 sleeved and mounted on the mounting axial end of the pulley, and an intermediate gear 52, the intermediate gear 52 being rotatably mounted on a horizontal bracket 6 at a middle position of the mounting bracket 2 and extending toward the driving gear 51, and the intermediate gear 52 and the driven gear 53 are kept in a constant meshing state; and driven by the swing motor 7, when the gap roller 1 swings to contact the belt, the intermediate gear 52 is correspondingly meshed and connected with the driving gear 51, and when the gap roller 1 swings away from the belt, the intermediate gear 52 is correspondingly separated from the driving gear 51. When the intermediate gear 52 is meshed and connected with the driving gear 51, the pulley at the output end of the belt can transmit the output power of the belt to the gap roller 1 through the transmission mechanism layer 5 to drive the gap roller 1 to rotate synchronously. At the same time, under the engagement of the intermediate gear 52, the rotation direction of the gap roller 1 is the same as the rotation direction of the pulley. While avoiding the above-mentioned winding problem, it can also effectively avoid the friction between the belt and the gap roller 1 causing equipment wear.

[0027] Anything not mentioned above is applicable to the prior art.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
