DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the utility model. Unless otherwise specified, all technical and scientific terms used in the utility model have the same meanings as those commonly understood by ordinary technicians in the technical field to which the utility model belongs. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] Embodiment 1

[0029] In a typical embodiment of the present application, a cigarette emptying auxiliary device for a cigarette storage and conveying system is provided, such as Figure 1-7 As shown, it includes a support 1, and a left top block 2 and a right top block 3 are respectively arranged on both sides of the support. The left top block 2 and the right top block 3 are respectively connected to the support 1 through an elastic member 4, and can be compressed and placed in the cigarette conveying channel, wherein the left top block contacts the conveyor belt on one side of the cigarette conveying channel, and the right top block contacts the conveyor belt on the other side of the cigarette conveying channel. One end of the left top block 2 and the right top block 3 are connected by a tensioning block, which is located on one side of the support and is used to support and lift the cigarette 9 in the conveying channel.

[0030] Specifically, Figure 2 , 6 As shown, the support 1 is a hollow box-shaped structure, and symmetrical mounting holes 11 are provided on the two sides of the support for connecting elastic members to install the left and right top blocks. In order to ensure a firm connection and stable elasticity, in this embodiment, two symmetrical pairs of mounting holes are provided, that is, four elastic members are required to complete the connection between the support and the left and right top blocks to achieve stable use. In other embodiments, the number can be adjusted accordingly.

[0031] like Figure 1-3 As shown, the left top block 2 is a sheet structure, and the outer side is an irregular plane composed of a plane and a curved surface, which can better fit the conveyor chain plate and increase friction. The inner side of the left top block is a plane, and a through center hole 21 is provided on the center line of the left top block 2 for connecting the elastic member. It is easy to understand that the position and size of the center hole 21 and the mounting hole 11 are set correspondingly. In this embodiment, two center holes are set on the left top block, and the structure and function of the right top block are completely consistent with those of the left top block.

[0032] like Figure 4 , 5 As shown, the elastic member 4 includes a coaxially arranged spring 41 and a guide shaft 42. One end of the guide shaft 42 is fixedly connected to the center hole 21 of the left top block or the right top block, and the other end passes through the mounting hole 11 and extends into the inner cavity of the support. The guide shaft 42 is in clearance with the mounting hole 11 and can slide relative to the mounting hole. The spring 41 is sleeved on the outer circumferential surface of the guide shaft, and the two ends of the spring are respectively connected and fixed to the left / right top block and the support. When the left top block and the right top block are subjected to pressure, the spring is compressed, the left top block and the right top block are relatively close, and the guide shaft slides along the mounting hole; when the pressure disappears, the spring elastic force drives the left and right top blocks to move relatively away. The guide shaft guides the deformation process of the spring and can ensure that the elastic force is parallel. In order to prevent the guide shaft from falling off from the mounting hole, in this embodiment, the guide shaft 42 passes through the mounting hole and is threaded at one end of the inner cavity of the support, and is matched and connected with an anti-slip nut 43 to ensure the stability of the structure.

[0033] The tension block is arranged on the opening side of the support, such as Figure 1 , 2As shown, the tension block includes a left tension block 5 fixedly connected to the left top block and a right tension block 6 fixedly connected to the right top block. The left and right tension blocks can slide relative to each other, thereby adjusting the relative distance between the left top block and the right top block. Specifically, the left tension block 5 and the right tension block 6 are both sheet-like structures, and the two are matched to form a staggered smooth tooth structure, which can slide relative to each other. A plurality of bolt holes are respectively provided at the distal ends of the left tension block 5 and the right tension block 6. The left tension block 5 is fixedly connected to the left top block 2 through the bolt holes, and the right tension block 6 is fixedly connected to the right top block 3 through the bolt holes. The bolt holes are matched with bolts to achieve a detachable connection.

[0034] In addition, if Figure 1 , 2 As shown in Figures 4 and 5, a limiter 7 is provided between the tension block and the support 1. The limiter includes two metal sheets with bolt holes. The two metal sheets are respectively installed on the inner and outer sides of the tension block. The inner metal sheet is placed in the inner cavity of the support, so that the support is in contact with the inner side of the tension block, and the device structure is more compact. Specifically, a connection hole is provided at the end of the left tension block close to the right tension block. Through the bolt holes on the connection block and the inner and outer metal sheets, the limiter is pressed against the inner and outer sides of the left tension block and connected with the left tension block bolts. The limiter plays a limiting role, ensuring that the left and right tension blocks slide relatively parallel to each other, avoiding dislocation or separation, and improving the stability of the left and right tension blocks during relative movement.

[0035] In addition, in order to make the operation more convenient and safer, a handle 8 is provided on the side of the support opposite to the opening surface. Figure 1 , 2 As shown, the handle is a cylindrical structure with a thread on the top, and the handle is connected to the closed surface of the support. A threaded hole 12 is provided on the closed surface of the support, and the threaded end of the handle 8 is threadedly connected to the support 1, which is convenient for installation and operation of the device.

[0036] In this embodiment, the handle, support, left top block, right top block, left tension block and right tension block are all made of engineering plastic 3D printing, which effectively reduces the overall weight of the device while meeting the connection strength requirements, and has low manufacturing costs. The limiter is made of stainless steel, which can effectively prevent the limiter from rusting and extend its service life.

[0037] The working principle of this embodiment:

[0038] In the cigarette storage and conveying system, cigarettes must pass through the lifting channel and the horizontal conveying channel successively to enter the cigarette warehouse. The cigarette emptying auxiliary device is used to empty the cigarettes in the cigarette conveying system at the end of production to avoid cigarette waste while ensuring that the quality of the cigarettes is not damaged.

[0039] like Figure 7As shown, when in use, the handle 8 is held to compress the left and right top blocks and place them behind the last cigarette 9 and between the two conveyor belts of the cigarette conveying channel. After being released, the left top block 2 can be in close contact with the first conveyor belt 10 on one side of the cigarette conveying channel, and the right top block 3 is in close contact with the second conveyor belt 13 on the other side of the cigarette conveying channel. The elastic member 4 is tensioned and supported, and the limit member 7 can limit the relative movement of the left tensioner and the right tensioner to achieve a stable use effect. The friction between the outer side surfaces of the left and right top blocks and the conveyor belt enables the device to move with the conveyor belt, so as to conveniently and quickly realize the emptying of cigarettes, avoiding the safety hazards of manually assisting in lifting cigarettes and the damage of cigarettes due to poor control of the force.

[0040] The utility model is simple to use, does not require the addition of other auxiliary tools, and has a compressible volume, and can adapt to different spacings of cigarette channels in a cigarette storage and conveying system. When in use, by placing the auxiliary device between two conveyor belts of the cigarette storage and conveying system, the cigarettes in the cigarette storage and conveying system can be quickly emptied, saving production time. At the same time, the cigarettes in the cigarette storage and conveying system can be fully emptied, avoiding the waste of cigarettes and achieving the purpose of reducing costs and increasing efficiency.

[0041] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
