The belt width of the middle group of the front three groups of belt transmission mechanisms 101 is greater than that of the other two groups, and the belt widths of the rear two groups of belt transmission mechanisms 102 are equal. The front three groups of belt transmission mechanisms 101 and the rear two groups of belt transmission mechanisms 102 are arranged on the frame 103 at intervals, wherein the front three groups of belt transmission mechanisms 101 and the rear two groups of belt transmission mechanisms are all connected to a power mechanism, the driven shafts of the rear two groups of belt transmission mechanisms 102 are the same as the driven shafts of the front three groups of belt transmission mechanisms 101, and the three groups of belt transmission mechanisms 101 and The rear two groups of belt transmission mechanisms 102 are staggered in pairs (that is, the rear two groups of belt transmission mechanisms 102 are arranged opposite to the intervals of the first three groups of belt transmission mechanisms 101), and share a driven shaft to realize transmission, so the structure is simplified, and the belts at the transition between the first three groups of belt transmission mechanisms and the rear two groups of belt transmission mechanisms transition continuously and smoothly, and there is no excessive deviation in direction and position. Two sets of push head mechanisms 4 are adopted, which are symmetrically arranged on both sides between the rear two groups of belt transmission mechanisms 102.

[0028] In this embodiment, the above-mentioned cigarette pressing component 2 includes a door frame 201, a pressing cylinder 202 and a pressing plate 203. The door frame 201 spans the rear side of the first three groups of belt transmission mechanisms 101 and is fixedly connected to the frame 103. The pressing plate 203 is fixedly connected to the cylinder rod of the pressing cylinder 202. The pressing cylinder 202 is fixedly connected to the top of the door frame 201 and can press the cigarettes after the cylinder rod is extended. In the subsequent program, when the amount of cigarettes entering reaches the set amount, the pressing cylinder is driven, and the cylinder rod of the pressing cylinder moves downward, pushing the pressing plate downward. When the pressing plate presses the cigarette, the cigarette is blocked and waits until the subsequent program (pushing The pressing plate 202 is a three-cylinder rod structure, which features fast and stable pushing, smooth pressing, and balanced force on the pressing plate. In order to avoid damage to the pressed cigarette strips, an elastic layer 204 made of rubber, sponge or other materials is fixedly connected to the bottom of the pressing plate 203.

The side wall panels of the horizontal U-shaped plate 207 are provided with two horizontal strip holes arranged up and down. The side wall panels are fixedly connected to the frame by screws passing through the horizontal strip holes. The horizontal strip holes are convenient for position adjustment of the horizontal U-shaped plate 207 (verification of the adjustment in the length direction of the conveyor belt machine). A bent horizontal plate is provided on the top of the horizontal U-shaped plate 207, and the horizontal plate faces the direction of the side wall panels.

The linear module 301 is fixedly connected to the frame through three connecting pieces 308, and the blocking mechanism is driven to move by the linear module. The blocking mechanism is in different positions, so that the number of cigarette strips placed on the rear half of the conveyor belt is different, and then when the number of cigarette strips fed reaches the number of cigarette strips required for packaging of the order, the blocking mechanism is pushed out, and the cigarette strips are pushed out for packaging through the pushing head mechanism, which is convenient for the control of the order cigarette strips, and the control is simple and convenient, wherein the blocking mechanism 302 comprises a limiting beam 303, a limiting baffle 304 and a limiting cylinder 305, wherein one end of the limiting beam 303 is fixedly connected to the slider of the linear module 301, and the other end is fixedly connected to the limiting cylinder 305, the cylinder rod of the limiting cylinder 305 is fixedly connected to the limiting baffle 304, and the cylinder rod extends out The rear limit baffle 304 can block the advancement of the cigarette strips. After the number of cigarette strips required by the order is determined, the limit cylinder is controlled to push out the limit baffle. After the limit baffle is pushed out, the bottom of the limit baffle is lower than the height of the cigarette strips, thereby blocking the cigarette strips. After reaching the set amount, the limit cylinder is controlled to release the limit baffle, and the push head mechanism is controlled to quickly push the cigarette strips out. The limit beam 303 includes a fixed frame for fixing the slider of the linear module and a cantilever plate beam fixedly connected to the fixed frame. It has light weight, simple structure, convenient installation, stable and reliable limiting. In order to reduce the weight of the limit baffle, the limit baffle 304 is an inverted U-shaped structure, and a reinforcing rib 306 is arranged on the rear side of the vertical plate. The U-shaped structure can increase the effective contact surface, and the limiting is reliable and stable. The reinforcing rib 306 increases the rigidity of the blocking limit baffle 304. The limit cylinder adopts a three-cylinder rod structure, and the pushing is smooth and reliable. A vertical magnetic photoelectric 307 is installed on the limit cylinder through an L-shaped bracket, and the magnetic photoelectric can detect the pushing of the cigarette strips.

[0032] Preferably, the pusher mechanism 4 comprises a pusher 401, a pusher chain 402 and a chain guide 403. The pusher chain 402 is provided in two rows and respectively sleeved on the driving shaft assembly 404 and the driven shaft assembly 405. The driving shaft assembly 404 and the driven shaft assembly 405 are both fixedly connected with sprockets sleeved with the pusher chain. The pusher 401 is fixedly connected to the corresponding positions of the two rows of pusher chains 402.

When the number of cigarette cartons of the set order is reached, the limit baffle is released, and the pusher head pushes out the ordered amount of cigarette cartons.

[0033] In order to prevent the cigarette strips from being pushed out too quickly, an elastic buffer belt 5 is installed on the frame 103 of the conveyor belt machine 1 above the discharge end of the pushing head mechanism 4. The buffer belt 5 is fixedly connected to the frame 103 by a belt fixing member 6. The pushed cigarette strips fall slowly under the action of the buffer belt to avoid damage caused by too fast a speed. The belt fixing member 6 includes an inclined plate 601 and connecting parts 602 arranged at both ends of the inclined plate 601. After the inclined plate 601 is fixedly connected to the buffer belt 5, the free end of the buffer belt 5 can be kept on the pallet outlet of the conveyor belt machine 1. The inclined belt fixing member makes it easy to tilt the buffer belt and place it gently on the pallet.

[0034] In summary, the utility model has the following advantages:

[0035] (1) The blocking and positioning mechanism temporarily blocks and stores the cigarette cartons that need to be separated and packaged. When the set amount is reached, the cigarette pressing component presses the cigarettes on the front half of the conveyor belt conveyor onto the conveyor belt as needed to prevent them from being transported forward, and the pusher mechanism is activated to push out the order quantity that needs to be packaged for packaging, thereby realizing the automatic cigarette carton separation and packaging process, improving the separation efficiency and separation accuracy;

[0036] (2) The first three groups of belt drive mechanisms and the last two groups of belt drive mechanisms share a driven shaft to achieve transmission, which simplifies the structure. In addition, the belts of the first three groups of belt drive mechanisms and the last two groups of belt drive mechanisms transition continuously and smoothly at the transition point, without excessive deviation in direction and position. The first three groups of belts and the last three groups of belts are arranged in an alternating manner, which can achieve stable transmission of cigarette strips.

[0037] (3) When the number of cigarettes entering the cigarette pressing component reaches the set number in the subsequent procedure, the pressing cylinder is driven to move the cylinder rod of the pressing cylinder downward, pushing the pressing plate downward. When the pressing plate presses the cigarettes, the cigarettes are blocked. After the subsequent procedure (after the push head is pushed out and re-limited) is completed, the pressing plate is released again to allow the next order of cigarettes to be delivered;

[0038] (4) Two limit plates are provided to block cigarette cartons whose height is greater than a set height or to block stacked cigarette cartons, so that cigarette cartons of a set height can enter for separation and packaging;

[0039] (5) The blocking positioning mechanism drives the blocking mechanism to move through the linear module. When the blocking mechanism is in different positions, the number of cigarette cartons placed on the rear half of the conveyor belt is different. When the number of cigarette cartons delivered reaches the number of cigarette cartons required for packaging in the order, the blocking mechanism is pushed out and the cigarette cartons are pushed out for packaging through the push head mechanism, which is convenient for order control and simple and convenient control.

[0040] (6) After the cylinder rod of the blocking mechanism is extended, the limit baffle can block the cigarette cartons from moving forward. After the number of cigarette cartons required by the order is determined, the limit cylinder is controlled to push out the limit baffle. After the limit baffle is pushed out, the bottom of the limit baffle is lower than the height of the cigarette cartons, blocking the cigarette cartons. After reaching the set amount, the limit cylinder is controlled to release the limit baffle, and the push head mechanism is controlled to quickly push out the cigarette cartons.

[0041] (7) The chain is driven by the sprocket drive motor to rotate, which in turn drives the pusher to move in a circular direction. When the number of cigarette cartons in the set order is reached, the limit baffle is released and the pusher pushes out the ordered number of cigarette cartons;

[0042] (8) A buffer belt is set up so that the pushed-out cigarette strips fall slowly under the action of the buffer belt to avoid damage caused by falling too quickly.
