Description

Technical Field

[0001] This utility model relates to the field of propagation and control technology, specifically to a striking device for sorting tobacco bins. Background Technology

[0002] In existing technologies, tobacco logistics and distribution centers widely use vertical tobacco bin sorting lines to sort cigarettes of different specifications. The striking structure of vertical tobacco bin sorting lines is mostly a fixed structure. During the sorting process of cigarettes of different specifications, when the sorting line needs to process cigarettes of another specification, the operators must stop the machine and use tools to physically replace the striking structure of the entire tobacco bin. This process includes disassembling the old striking structure, installing a new striking structure that matches the size, and readjusting it.

[0003] Chinese patent CN118060218A discloses a vertical sorting machine capable of bidirectional smoke output, including a frame, a sorting cigarette bin mechanism disposed on the frame for storing cigarette packs, a first sorting transport mechanism and a second sorting transport mechanism disposed on both sides of the sorting cigarette bin mechanism for transporting cigarette packs, and a striking mechanism disposed on the frame for moving cigarette packs in the sorting cigarette bin mechanism to the first sorting transport mechanism or the second sorting transport mechanism.

[0004] The aforementioned striking mechanism has a simple and fixed structure. When different specifications of cigarette packs need to be sorted, a corresponding striking mechanism needs to be selected. Disassembling and installing a new striking mechanism leads to excessive downtime on the production line, which seriously reduces the overall operational efficiency of the sorting center. This is especially prominent when handling orders with multiple varieties and small batches. At the same time, a dedicated striking structure needs to be equipped for each type of cigarette pack, resulting in a large variety and quantity of spare parts, complex warehouse management, and high capital occupation.

[0005] The present invention aims to overcome the defects in the prior art and provide a simple, efficient, and cost-controllable striking device for sorting tobacco warehouses.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a striking device for sorting cigarette packs, comprising a base support and a chain drive structure mounted on the base support; the chain drive structure includes a chain and a drive sprocket, a driven sprocket, and a tension sprocket that rotate synchronously through the chain, and striking blocks for sorting cigarette packs are mounted on the chain; the drive sprocket has a drive shaft that rotates synchronously with the drive sprocket in the middle, and an external transmission belt for driving the drive shaft to rotate is provided on the drive shaft; the driven sprocket has a driven shaft that is rotatably connected to the driven sprocket in the middle, and an adjustment component for adjusting the horizontal position of the driven shaft is provided on the base support; the tension sprocket has a tension shaft that is rotatably connected to the tension sprocket in the middle, and a tension groove is formed on the base support to allow the tension shaft to slide down.

[0007] In a preferred embodiment of this utility model, the driving sprocket and the driven sprocket are located at the same horizontal level, the tensioning sprocket is located between the driving sprocket and the driven sprocket, and the tensioning sprocket is located below the driving sprocket and the driven sprocket.

[0008] As a preferred embodiment of this utility model, a transmission wheel that rotates synchronously with the drive shaft is mounted on the drive shaft, and an external transmission belt is connected to the transmission wheel.

[0009] As a preferred embodiment of the present invention, the adjustment assembly includes a support frame and an adjustment screw connected to the support frame. The adjustment screw passes through a driven shaft, and the driven shaft is provided with an adjustment nut for positioning the horizontal position of the adjustment screw.

[0010] In a preferred embodiment of this utility model, the adjusting nut is located between the driving shaft and the driven shaft, and the support frame is provided with two adjusting screws respectively corresponding to the two ends of the driven shaft.

[0011] As a preferred embodiment of this utility model, the tensioning groove is a vertical groove formed on the base support, and the bottom of the base support is provided with a tensioning spring for tensioning the tensioning shaft.

[0012] As a preferred embodiment of this utility model, the striking block includes an upper connecting block and a lower connecting block for clamping the chain, and an adjustable-height striking body is mounted on the upper connecting block.

[0018] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figures 1-7As shown, a striking device for sorting cigarette packs includes a base support 1 and a chain drive structure 2 mounted on the base support 1. The chain drive structure 2 includes a chain 27 and a drive sprocket 21, a driven sprocket 22, and a tension sprocket 23 that rotate synchronously through the chain 27. A striking block 4 for sorting cigarette packs is mounted on the chain 27. The drive sprocket 21 has a drive shaft 24 that rotates synchronously with the drive sprocket 21 in the middle, and an external transmission belt 29 for driving the drive shaft 24 to rotate is provided on the drive shaft 24. The driven sprocket 22 has a driven shaft 25 that is rotatably connected to the driven sprocket 22 in the middle, and an adjustment component 3 for adjusting the horizontal position of the driven shaft 25 is provided on the base support 1. The tension sprocket 23 has a tension shaft 26 that is rotatably connected to the tension sprocket 23 in the middle, and a tension groove 11 is formed on the base support 1 to allow the tension shaft 26 to slide down.

[0020] A drive wheel 28 that rotates synchronously with the drive shaft 24 is installed on the drive shaft 24. An external drive belt 29 is connected to the drive wheel 28. The external drive belt 29 is driven by an external motor and a corresponding external drive wheel, thereby driving the drive shaft 24 and the drive sprocket 21 on the drive shaft 24 to rotate, driving the chain 27 to drive, and synchronously driving the driven sprocket 22 and the tension sprocket 23 to rotate under the transmission action of the chain 27. Under the transmission action of the chain 27, the striking block 4 is moved, and the sorting operation is achieved by the movement of the striking block 4.

[0021] The driving sprocket 21 and the driven sprocket 22 are at the same horizontal level, and the tensioning sprocket 23 is located between the driving sprocket 21 and the driven sprocket 22, and is located below the driving sprocket 21 and the driven sprocket 22.

[0022] Under the action of the driving sprocket 21 and driven sprocket 22 at the same height, the horizontal movement of the impact block 4 is controlled to achieve the sorting function. At the same time, the tensioning sprocket 23 located below the driving sprocket 21 and driven sprocket 22 effectively tensions the chain 27 without affecting the normal operation of the impact block 4.

[0023] The adjustment assembly 3 includes a support frame 31 and an adjustment screw 32 connected to the support frame 31. The adjustment screw 32 passes through the driven shaft 25, and the driven shaft 25 is provided with an adjustment nut 33 for positioning the horizontal position of the adjustment screw 32. The adjustment nut 33 is located between the drive shaft 24 and the driven shaft 25. The support frame 31 is provided with two adjustment screws 32 respectively corresponding to the two ends of the driven shaft 25.

[0024] During the transmission process of chain 27, driven shaft 25 is always in a relatively stationary state, and under the tension of chain 27, driven shaft 25 is always in contact with adjusting nut 33 to achieve positioning of driven shaft 25.

[0025] The adjusting screw 32 is set along the straight line of the driven sprocket 22 and the tensioning sprocket 23. When it is necessary to adjust the striking length of the striking block 4, simply rotate the adjusting nut 33 that abuts against the driven shaft 25 to adjust the position of the driven shaft 25 on the adjusting screw 32, thereby adjusting the relative distance between the driving sprocket 21 and the driven sprocket 22, thereby adjusting the length of the chain 27 between the driving sprocket 21 and the driven sprocket 22, and thus adjusting the striking length of the striking block 4.

[0026] The tension groove 11 is a vertical groove formed on the base bracket 1. The bottom of the base bracket 1 is provided with a tension spring 5 for tensioning the tension shaft 26. Under the position adjustment of the driven sprocket 22, since the total length of the chain 27 remains unchanged, the position of the tension shaft 26 changes accordingly with the adjustment of the driven sprocket 22. The tension spring 5 is used to pull the tension shaft 26 downward to ensure the tension of the chain 27.

[0027] Under the action of the tensioning groove 11, the tensioning sprocket 23 falls under its own weight, thereby tensioning the chain 27. At the same time, under the action of the tensioning spring 5, the chain 27 is further tensioned.

[0028] The striking block 4 includes an upper connecting block 41 and a lower connecting block 42 that hold the chain 27. An adjustable striking body 43 is installed on the upper connecting block 41. A lifting screw 44 connected to the upper connecting block 41 passes through the striking body 43. The striking body 43 and the lifting screw 44 are threadedly connected. The bottom of the lower connecting block 42 is provided with a connecting screw 45 that connects to the upper connecting block 41.

[0029] The upper connecting block 41 and the lower connecting block 42 are located on the upper and lower sides of the chain 27, respectively. The upper connecting block 41 and the lower connecting block 42 are set through the chain link to achieve clamping on the chain 27. At the same time, under the action of the connecting screw 45, the upper connecting block 41 and the lower connecting block 42 are detachably connected.

[0030] Since the striking body 43 is threadedly connected to the lifting screw 44, and the lifting screw 44 is tightened to the upper connecting block 41, the height of the striking body 43 can be adjusted by rotating the striking body 43, and the height of the striking body 43 can also be adjusted by replacing the striking body 43.

[0031] A bearing is provided between the drive shaft 24 and the drive sprocket 21, and a bearing is also provided between the tension shaft 26 and the tension sprocket 23.

[0032] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0033] Although this document frequently uses reference numerals from the accompanying drawings, such as: base support 1, tension groove 11, chain drive structure 2, drive sprocket 21, driven sprocket 22, tension sprocket 23, drive shaft 24, driven shaft 25, tension shaft 26, chain 27, drive wheel 28, external drive belt 29, adjusting assembly 3, support frame 31, adjusting screw 32, adjusting nut 33, striking block 4, upper connecting block 41, lower connecting block 42, striking body 43, lifting screw 44, connecting screw 45, tension spring 5, etc., the possibility of using other terms is not excluded.
