[0002] In the process of tobacco shred processing, the horizontal conveyor slicer needs to slice the whole package of tobacco leaves. The slicing process is mainly to clamp the push plate and the baffle, and then the cutter moves downward under the drive of the chain to complete the cutting of the tobacco leaves.

[0025] 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.

[0026] like Figure 1As shown, the clamping device of the horizontal conveyor slicer provided in this embodiment comprises: a feeding belt 1 arranged in the horizontal direction, the feeding belt 1 is used to convey the cigarette pack 6 to the slicing position, a push plate 2 and a baffle 4 which can move left and right are respectively arranged on both sides of the slicing position of the cigarette pack 6, a cutter 3 which can move up and down in the vertical direction is arranged above the slicing position of the cigarette pack 6, the push plate 2 is driven by a push plate motor, a distance detection component is arranged near the slicing position of the cigarette pack 6, the distance detection component is electrically connected to the input end of the controller, and the distance detection component is used to detect whether the cigarette pack 6 is conveyed to the right position, so as to obtain The cigarette pack delivery signal is also used to detect the thickness of the cutter 3 to obtain the cutter thickness information, and send the cigarette pack delivery signal and the cutter thickness information to the controller, and the push plate motor and the cutter 3 are electrically connected to the output end of the controller; the controller is used to control the slicing action of the cutter 3 cutting the cigarette pack 6 according to the cigarette pack delivery signal, and after slicing is completed, output a retreat instruction to the push plate motor according to the cutter thickness information; the baffle motor is used to respond to the retreat instruction and drive the push plate 2 to move a preset distance in the direction away from the cigarette pack 6.

[0027] The distance detection component is a photoelectric sensor, and the controller is a programmable logic controller (PLC). In the present invention, the model of the controller may be, for example, S7-300. It should be noted that the present invention does not specifically limit the location, type, and model of the photoelectric sensor and the controller.

[0028] Furthermore, the push plate 2 is located on the right side of the cigarette pack 6, the baffle 4 is located on the left side of the cigarette pack 6, and the lowest points of the push plate 2 and the baffle 4 are located above the highest point of the feed belt 1. The projection of the right end point of the cutter 3 on the feed belt 1 is located to the left of the left end point of the feed belt 1; when the feed belt 1 is used to transport the cigarette pack 6 to the slicing position, the portion of the cigarette pack 6 to be cut extends beyond the left end point of the feed belt 1. Considering that in order to ensure that the cigarette slices are completely cut, the distance of the cutter 3 is greater than the thickness of the cigarette pack 6, if the cigarette pack is completely supported by the feed belt 1, the cutter 3 will scratch the feed belt 1. Therefore, the feed belt 1 partially supports the cigarette pack, which can prevent the cutter 3 from scratching the feed belt 1 when slicing. In a specific implementation, the lowest point and the highest point of the push plate 2 and the baffle 4 can be the same or different, and the utility model does not make specific restrictions on this.

[0029] Furthermore, the clamping device of the horizontal conveyor slicer also includes a bracket 5, the bracket 5 and the baffle 4 are arranged on the same side of the cigarette pack 6, and the bracket 5 is arranged at a right angle to the part to be cut of the cigarette pack 6. The shape of the bracket 5 is L-shaped, and the bracket 5 includes a horizontal part and a vertical part. The length of the vertical part is greater than the length of the horizontal part. The top of the horizontal part is flush with the top of the feeding belt 1, and the vertical part is parallel to the baffle 4, and the vertical part is arranged outside the baffle 4. The utility model supports the cigarette pack 6 by the bracket 5 and the feeding belt 1.

[0030] Furthermore, the horizontal conveyor slicer clamping device also includes a baffle motor for driving the baffle 4 to move, and the baffle motor is electrically connected to the output end of the controller. The controller is also used to control the movement of the push plate motor and the baffle motor according to the cigarette pack delivery signal, so that the push plate motor and the baffle motor respectively drive the push plate 2 and the baffle 4 to move in the direction close to the cigarette pack 6 to clamp the cigarette pack 6, and after the push plate 2 and the baffle 4 move into place, the distance (S1) between the push plate 2 and the baffle 4 is the same as the length of the cigarette pack. In this way, when the cutter 3 is slicing, it can ensure that the push plate 2 and the baffle 4 clamp the cigarette pack as tightly as possible, which can prevent the push plate 2 and the baffle 4 from being clamped too tightly, and the distance (S1) between the push plate 2 and the baffle 4 will be greater than the length of the cigarette pack, resulting in the cigarette pack loosening and uneven slicing during slicing; at the same time, it can also prevent the push plate 2 and the baffle 4 from being clamped too tightly, and the distance (S1) between the baffle 4 and the push plate 2 remains unchanged during the slicing process. After slicing, the tobacco slices have an extrusion effect on the cutter 3, resulting in damage to the tobacco slices, increasing the crushing and the slicer jamming, and the scattered tobacco leaves will interfere with the operation of the distance detection component.

[0031] Furthermore, after the push plate 2 is retracted into position, the distance between the push plate 2 and the baffle 4 is the sum of the cigarette pack length and the preset knife withdrawal gap. This ensures that when the cutter 3 is lifted, the push plate 2 is retracted to leave enough knife lifting gap, increasing the knife withdrawal gap, and eliminating the squeezing force of the cigarette on the cutter.

[0032] Furthermore, the cutter 3 is connected to the output end of the controller, and the controller is also used to control the lifting action of the cutter 3 after the push plate 2 moves a preset distance in a direction away from the cigarette pack 6.

[0033] Furthermore, the horizontal conveyor slicer clamping device also includes a gravity sensor and a belt motor for driving the feeding belt 1 to move. The gravity sensor is arranged below the entrance end of the feeding belt 1, and the gravity sensor is electrically connected to the input end of the controller. The gravity sensor is used to detect whether the cigarette pack 6 enters the feeding belt 1 to obtain a cigarette pack entry signal; the belt motor is electrically connected to the output end of the controller, and the controller is also used to control the belt motor to start according to the cigarette pack entry signal, control the belt motor to stop running according to the cigarette pack delivery signal, and control the belt motor to continue to start after the cutter 3 is retracted.

[0034] Specifically, the baffle motor, and / or the push plate motor, and / or the belt motor are stepper motors, which facilitate fine control of the movement of the baffle 4, the push plate 2 and the feeding belt 1. The model of the stepper motor can be, for example, 57BYGH350E. It can be understood by those skilled in the art that the models of the stepper motors corresponding to the baffle motor, the push plate motor and the belt motor can be the same or different, and the utility model does not specifically limit this. It should be noted that the utility model does not specifically limit the type and model of the stepper motors corresponding to the baffle motor, the push plate motor and the belt motor.

[0035] During operation, after the cigarette pack 6 is transported to the right position by the feeding belt 1, the push plate 2 and the baffle 4 clamp the cigarette pack 6, and the cut part is lifted by the bracket 5. The cutter 3 cuts the first piece of tobacco leaf raw material. After the cigarette pack is sliced, the baffle 4 and the bracket 5 move clockwise to loosen the cut tobacco leaf raw material, and the tobacco leaf raw material falls down by gravity and is transported to the next production process; after the push plate 2 retreats to leave enough clearance for lifting the knife, the cutter 3 lifts the knife upward.

[0036] The clamping device of the horizontal conveying slicer provided by the embodiment of the utility model, after the cigarette pack is transported to the position by the feeding belt, the cigarette pack is clamped by the push plate and the baffle plate. The controller controls the slicing action of the cutter to cut the cigarette pack according to the signal that the cigarette pack is transported to the position, and controls the baffle plate to move away from the cigarette pack after the slicing is completed, which can ensure that the clamping force of the push plate and the baffle plate is sufficient during slicing to make the slices neat; and ensure that the gap when lifting the knife is sufficient to avoid tobacco leaf crushing and prevent the slicer from getting stuck, thereby reducing the failure rate of the slicer.

[0037] So far, various embodiments of the present disclosure have been described in detail. In order to avoid obscuring the concept of the present disclosure, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed here.

It should be understood by those skilled in the art that the above embodiments may be modified or some technical features may be replaced by equivalents without departing from the scope and spirit of the present disclosure.
