Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of new energy vehicle maintenance, more particularly, to a cartoning machine cigarette buffer device. BACKGROUND

[0002] In the cigarette production and manufacturing process, after the completion of the small box wrapping, the cigarette rod is wrapped, and finally transported to the cartoning machine through the cigarette rod elevator and the cigarette rod conveying belt for the cartoning of the cigarette rod. The cigarette rod cartoning machine stacks two layers of 25 cigarette rods through a series of process flows, that is, a layout of 25 cigarette rods per layer. When the cigarette rod is stacked, the cigarette rod is accelerated by the transverse acceleration device of the cartoning machine, and then input to the stacking device for stacking and cartoning in the 25x2 mode. In the actual production process, due to various factors, there are many cigarette rods on the cigarette rod conveying belt. A large number of cigarette rods need to be accelerated by the transverse acceleration device and then enter the cigarette rod stacking device. At this time, the movement of the cigarette rod in the horizontal direction stops, but due to the action of the transverse acceleration device, the speed of the cigarette rod is too fast before entering the stacking device, and the cigarette rod needs to overcome the inertia action when stopping moving. If there are too many cigarette rods, the frontmost cigarette rod will be subjected to a huge impact force from the cigarette rods conveyed behind, resulting in deformation of the cigarette rod, and even bending and deformation of the cigarette in the inner cigarette package, causing quality defects.

[0003] Therefore, how to provide a buffer device that can effectively slow down the conveyed cigarette rod and avoid the extrusion of a large number of cigarette rods on the frontmost cigarette rod has become a technical problem to be solved in the field. SUMMARY

[0028] It should be noted that like numbers and letters refer to like items throughout the drawings, and that, once an item is defined in one drawing, it should not require further discussion in subsequent drawings.

[0029] In accordance with Figs. 1 to 3As shown, the present application provides a cartoning machine cigarette strip buffering device 3, which is arranged between a cigarette strip accelerating belt 1 and a cigarette strip stacking device 4, the cigarette strip accelerating belt 1 is used to deliver cigarette strips 2 to the cigarette strip stacking device 4, and a cartoning device 5 is further connected to the rear side of the cigarette strip stacking device 4 and used to carton the cigarette strips 2; the cigarette strip buffering device 3 comprises a guide rail 31, a buffering brush 33 and a connecting seat 32.

[0031] The present application installs the buffering brush 33 on the right side of the cigarette strip stacking device 4, the height of the buffering brush between the buffering brush and the cigarette strip accelerating device is slightly smaller than the height of one cigarette strip 2, the length of the buffering brush is consistent with the length of the cigarette strip 2, and the width of the buffering brush is smaller than the width of the cigarette strip 2; when a large number of cigarette strips 2 are delivered to the front end of the cigarette strip stacking device 4 through the cigarette strip accelerating belt 1 and pass through the buffering brush 33, the height of the buffering brush 33 and the cigarette strip accelerating belt 1 is slightly smaller than the thickness of the cigarette strip 2, at this time, the cigarette strip 2 overcomes the friction and slows down under the extrusion of the buffering brush 33, so that the impact force generated by the cigarette strip 2 being delivered to the cigarette strip stacking device 4 at a relatively large speed is avoided, the cigarette strip 2 at the front end is extruded, and quality defects occur.

[0032] Further, the first folded edge 321 is connected with the guide rail 31, the second folded edge 322 is inwardly bent, and the side of the second folded edge 322 facing the cigarette strips 2 is further provided with an auxiliary brush matched with the side surface of the cigarette strips 2. The auxiliary brush is installed at the lower part of the connecting seat 32 and in contact with the right side of the cigarette strips 2, which can further slow down the passing cigarette strips 2 and strengthen the slowing down effect. Through the multiple buffering devices, deformation of the cigarette strips 2 or damage of the cigarette packs is avoided, and the production cost is saved.

[0033] Further, the top of the first folded edge 321 is provided with an opening 323, the guide rail 31 is clamped in the opening 323, so that the connecting seat 32 can slide along the guide rail 31; the two ends of the top of the opening 323 are connected through adjusting bolts 35 to adjust the inner diameter of the opening 323, so that the connecting seat 32 can be stably arranged on the guide rail 31. In the implementation process, by adjusting the specific position of the connecting seat 32 on the guide rail 31, the position of the slowing down of the cigarette strips 2 can be changed, so as to accurately control the cartoning efficiency of the cigarette strips 2, and the slowed down cigarette strips 2 pass through the buffering brush 33 and are accelerated again through the remaining cigarette strip accelerating belt 1, avoiding the stacking failure problem caused by the low speed.

[0034] Further, the top of the second fold edge 322 is provided with a connecting hole, and the end of the buffer brush 33 close to the connecting seat 32 is provided with an L-shaped connecting rod 34, one end of the connecting rod 34 is slidingly connected in the connecting hole, so as to adjust the gap between the buffer brush 33 and the cigarette accelerating belt 1. The height of the buffer brush 33 can be adjusted relative to the cigarette accelerating belt 1, so that different deceleration effects of the cigarette 2 can be realized, and the applicability of the present application is increased.

[0035] Further, at least one set screw 36 is arranged on any one side of the second fold edge 322, and the set screw 36 cooperates with the connecting rod 34, so that the connecting rod 34 is fixed in the connecting hole.

[0036] Further, the cross section of the connecting rod 34 and the connecting hole are both non-circular structures. Since the buffer brush 33 of the present application is connected with the connecting seat 32 only through the connecting rod 34, in order to prevent the connecting rod 34 from rotating axially in the connecting seat 32, so as to cause the buffer brush 33 to deviate. The cross section of the connecting rod 34 and the connecting hole are both set to non-circular structures, so as to effectively avoid the above-mentioned problems. In addition, the present application can also be provided with guide rails 31 and connecting seats 32 on both sides of the cigarette accelerating belt 1, and the two ends of the buffer brush 33 are respectively provided with connecting rods 34, which are connected with the corresponding connecting seats 32, and the above-mentioned problems can also be avoided.

[0037] Further, the other side of the cigarette accelerating belt 1 away from the guide rail 31 is provided with a protective plate. The position of the cigarette 2 is protected by the protective plate, and the side close to the connecting seat 32 can also be provided with a low protective plate.
