Description

Technical Field

[0001] The present application relates to the technical field of tobacco processing, and in particular to a material leveling device and a shredder. Background Art

[0002] The tobacco industry's current tobacco cutting machine feeder carts use a motor-driven eccentric device to transmit force to the feed trough, which vibrates and delivers the tobacco to the cutter's copper chain.

DETAILED DESCRIPTION

[0022] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application.

[0023] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0024] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0025] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0026] Please refer to Figures 1 to 3 The material leveling device provided in the embodiment of the present application is used for a shredder, and the shredder includes a box body, and the box body is provided with a accommodating chamber. It can be understood by those skilled in the art that the box body is also provided with a feeding port connected to the accommodating chamber. In this embodiment, the loaded tobacco is added into the accommodating chamber from the feeding port by a feeding trolley, and after the tobacco enters the accommodating chamber, it will pass through the copper chain of the shredder and be transported to the cutter roller of the shredder by the copper chain of the shredder, and then the cutter roller will cut the tobacco, thereby completing the shredding process of the tobacco. However, due to the vibration of the feeding trough, the tobacco on the copper chain will be uneven and not pressed firmly, which will cause the knife gate of the cutter roller to run away from the stem or the slice when cutting, affecting the quality of the shredded tobacco, and the quality of the shredded tobacco cutting process is an important guarantee for the quality of the subsequent finished product.

[0027] The material leveling device provided in the embodiment of the present application includes: a support strip 100, an adjusting rod 200, a first support rod 300, a material leveling plate 400 and two positioning screw sleeves 500; the middle part of the support strip 100 is connected to the adjusting rod 200 near the upper end, and the lower end of the adjusting rod 200 is rotatably connected to the middle part of the first support rod 300; the material leveling plate 400 is provided with a guide groove 410, and includes a fixedly connected arc section 411 and a leveling section 412; the two ends of the first support rod 300 are respectively detachably fixedly connected to the opposite sides of the arc section 411; the two positioning screw sleeves 500 are respectively detachably connected to the opposite sides of the leveling section 412, and respectively extend outwards of the guide groove 410.

[0028] In this embodiment, since the lower end of the adjustment rod 200 is rotatably connected to the middle portion of the first support rod 300, when the adjustment rod 200 moves up and down along the support clip 100, no jamming occurs between the adjustment rod 200 and the first support rod 300. In this embodiment, the guide chute 410 connects the feeding trolley and the copper bar chain of the shredder. Specifically, the feeding trolley feeds the material into the copper bar chain of the shredder through the guide chute 410, and the copper bar chain then transports the tobacco to the cutter roller for cutting. Specifically, in this embodiment, the curved section 411 of the guide chute 410 is connected to the feeding trolley, and the flat section 412 of the guide chute 410 is connected to the copper bar chain. This prevents the tobacco from the feeding trolley from falling directly onto the copper bar chain. Instead, the tobacco first falls into the curved section 411, then passes through the curved section 411 into the flat section 412, and finally enters the copper bar chain through the flat section 412. Those skilled in the art will appreciate that when the tobacco falling from the feeding trolley into the arc section 411 is uneven, the tobacco will not immediately enter the copper bar chain, but will instead remain at the flattening section 412, with the tobacco behind pushing the tobacco in front into the copper bar chain; and when the tobacco behind pushes the tobacco in front, if the tobacco is uneven, the tobacco behind will supplement the uneven portion of the tobacco in front, so that the tobacco that finally enters the copper bar chain is uniform and flat, thereby ensuring that the tobacco on the copper bar chain entering the cutter roller is uniform and flat, and ensuring the cutting quality of the tobacco. Those skilled in the art will appreciate that in this embodiment, the side of the material level leveling plate 400 close to the flattening section 412 is called the front side, and the side of the material level leveling plate close to the arc section 411 is called the back side.

[0029] Those skilled in the art will also appreciate that the height of the flattening section 412 on the side closest to the curved section 411 is no greater than the height of the flattening section 412 on the side further away from the curved section 411. In this embodiment, the height refers to the distance from the plane of the copper bar chain. This prevents tobacco from the feeding trolley from sliding directly through the leveling plate 400 into the copper bar chain, thereby ensuring that the tobacco entering the copper bar chain through the leveling plate 400 is smooth and even.

[0030] The material leveling device is located in the accommodating chamber, and the opposite ends of the support clip 100 are respectively connected to the upper sides of the two opposite side walls of the accommodating chamber. Specifically, the box body has two side plates arranged opposite to each other, and the two opposite sides of the two side plates constitute the opposite side walls of the accommodating chamber. The two ends of the support clip 100 are vertically fixed with a snap-in plate 110, and the upper end surfaces of the two side plates arranged opposite to each other of the box body are provided with snap-in grooves, and the two snap-in plates 110 are respectively inserted into the two snap-in grooves, so that the support clip 100 is fixed to the upper side of the accommodating chamber. It can be understood by those skilled in the art that the two side plates may not have snap-in grooves, and the support clip 100 can be directly snapped onto the outer wall surfaces of the two side plates through the snap-in plate 110 to realize the connection between the support clip 100 and the upper side of the accommodating chamber.

[0031] The two positioning screw sleeves 500 respectively abut against the lower sides of the two opposite side walls of the accommodating chamber. This arrangement can avoid punching holes on the side walls of the accommodating chamber, thus avoiding damaging the structural strength of the side walls of the accommodating chamber and ensuring the service life of the shredder.

[0032] In one embodiment, the connection between the arcuate segment 411 and the flat segment 412 is smooth. Those skilled in the art will appreciate that a smooth transition can reduce resistance to tobacco entering the sliding segment from the arcuate segment 411, thereby preventing tobacco from accumulating at the transition and ensuring that tobacco entering the flat segment 412 flows evenly and continuously.

[0033] In one embodiment, the arc segment 411 is tangent to the flat segment 412. This arrangement makes processing simple and convenient.

[0034] In one embodiment, the flattened section 412 is parallel to the plane of the copper chain. This arrangement reduces the resistance of the tobacco in the flattened section 412 to entering the copper chain, while also facilitating control of the thickness of the tobacco in the flattened section 412.

[0035] In one embodiment, the outer peripheral surface of the positioning screw sleeve 500 is provided with an external thread, and the opposite sides of the flattening section 412 are respectively provided with a first threaded hole, and the positioning screw sleeve 500 is screwed into the first threaded hole through the external thread. Specifically, the external thread of the positioning screw sleeve 500 cooperates with the first threaded hole, and one end of the positioning screw sleeve 500 abuts against the side wall of the accommodating cavity. In this way, by adjusting the position of the positioning screw sleeve 500 in the first threaded hole, the side wall of the accommodating cavity of the material leveling plate 400 is adjusted to a relative position. That is, by adjusting the distance between the two sides of the flattening section 412 and the side wall of the accommodating cavity, it is possible to ensure that the flattening section 412 is aligned with the copper bar chain, and to ensure that the tobacco accurately falls into the copper bar chain from the flattening section 412.

[0036] In one embodiment, the material leveling device further includes a second support rod 600, and the second support rod 600 is provided with external threads on both sides thereof, and the two positioning screw sleeves 500 are provided with second threaded holes 510, and the second support rod 600 is located in the guide groove 410, and the second support rod 600 is screwed to the second threaded holes 510 on both sides thereof. In the embodiment of the present application, the second support rod 600 is provided, on the one hand, to increase the structural strength between the two side walls of the flattening section 412, and to avoid deformation of the two side walls of the flattening section 412 due to the extrusion of the positioning screw sleeve 500. On the other hand, since the second support rod 600 and the two positioning screw sleeves 500 are screwed together, the spacing between the positioning screw sleeve 500 and the two side walls can be adjusted by rotating the second support rod 600, thereby facilitating the adjustment of the position of the flattening section 412.

[0037] In one embodiment, the material leveling device further includes two first locking nuts 520, which are respectively threadedly connected to the two positioning screw sleeves 500 and abut against the groove wall of the guide groove 410. In this embodiment, since the second support rod 600 and the positioning screw sleeve 500 are threadedly connected, when the second support rod 600 is rotated, the positioning screw sleeve 500 can be driven to rotate in the first threaded hole. Therefore, the provision of the first locking nuts 520 can prevent the positioning screw sleeve 500 from rotating in the first threaded hole when the second support rod 600 is installed, causing the flattening section 412 to shift, thereby ensuring that the flattening section 412 is accurately aligned with the copper bar chain.

[0038] In one embodiment, the material leveling device further includes two second locking nuts 610, which are respectively screwed to opposite sides of the second support rod 600 and respectively abut against the two first locking nuts 520. In this embodiment, the purpose of providing the second locking nuts 610 is to adjust the positioning screw sleeve 500 through the second support rod 600. For example, when it is necessary to adjust the positioning screw sleeve 500, it is only necessary to loosen the first locking nut 520 and tighten the second locking nut 610. At this time, the second support rod 600 can be rotated so that the second support rod 600 drives the positioning screw sleeve 500 to rotate in the first threaded hole, thereby achieving the adjustment of the positioning screw sleeve 500.

[0039] In one embodiment, the material leveling device further includes two third locking nuts 310, and external threads are provided on opposite sides of the first support rod 300. The two third locking nuts 310 are respectively screwed to opposite sides of the first support rod 300 and abut against the groove wall of the guide groove 410. In this embodiment, by providing the third locking nut 310, the first support rod 300 can be prevented from falling out of the arc segment 411. Specifically, both sides of the arc segment 411 are through holes. During installation in this embodiment, the two third locking nuts 310 are first screwed into the external threads at both ends of the first support rod 300, and then the two ends of the first adjustment rod 200 are respectively inserted into the through holes, and finally the third locking nut 310 is screwed and the third locking nut 310 is abutted against the groove wall of the guide groove, and the installation is completed, which is convenient and quick.

[0040] In one embodiment, the material leveling device further includes two adjusting nuts 210, the adjusting rod 200 is provided with an external thread, the adjusting rod 200 passes through the middle of the support clip 100, and the two adjusting nuts 210 are respectively screwed to the adjusting rod 200; and the support clip 100 is clamped between the two adjusting nuts 210. In the embodiment of the present application, by providing two adjusting nuts 210, the height of the arc segment 411 can be adjusted, that is, the height of the two ends of the flattening segment 412 can be adjusted, thereby ensuring that the height of the end of the flattening segment 412 close to the arc segment 411 is not greater than the height of the end of the flattening segment 412 away from the arc segment 411, thereby ensuring that the tobacco is evenly and flatly formed when it falls from the flattening segment 412 to the copper bar chain. The specific adjustment method is a prior art and will not be described in detail here.

[0041] In one embodiment, an opening 620 is further provided in the middle of the second support rod 600. To rotate the second support rod 600, one end of a rectangular long rod can be inserted into the opening 620, and the other end of the long rod can be rotated to achieve rotation of the second support rod 600. This utilizes the principle of leverage to achieve rotation of the second support rod 600, which saves effort and facilitates operation.

[0042] The present application also provides a shredder, comprising a housing and any one of the above-mentioned leveling devices. In the shredder of this embodiment, the leveling device is used to add shredded tobacco, thereby ensuring that the shredded tobacco entering the shredder is flat and uniform, thereby ensuring the quality of the cut tobacco.

[0043] Although some specific embodiments of the present application have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application.
