Description

Technical Field

[0001] This utility model relates to a tobacco sheet alignment device for a belt conveyor, belonging to the technical field of secondary tobacco sheet splitting. Background Technology

[0002] On tobacco processing lines, tobacco leaves are typically conveyed by belt conveyors to a secondary splitting unit for sorting. To ensure effective sorting, the tobacco leaves need to be centered and stable before entering the secondary splitting unit. However, in actual production, due to factors such as belt vibration, uneven friction, or irregular tobacco leaf shape, the tobacco leaves are prone to misalignment during transport, causing them to deviate from the working center of the secondary splitting unit. This affects the sorting effect and can even lead to equipment jamming or shutdown.

[0003] In the existing technology, some production lines attempt to correct the position of the tobacco leaves by manually adjusting them or by installing a fixed limit plate on one side of the conveyor belt. However, the above methods have problems such as low automation, inconvenient adjustment, and low efficiency, and are difficult to adapt to the continuous conveying process of tobacco leaves of different thicknesses and sizes. Utility Model Content

[0004] The purpose of this invention is to overcome the problem that the tobacco flakes are prone to positional deviation during the existing belt conveyor tobacco flakes conveying process, resulting in unstable insertion and dispersing effect of the secondary fork splitter.

[0005] To solve the above-mentioned technical problems, this utility model is implemented using the following technical solution: A device for aligning tobacco flakes on a belt conveyor is provided, comprising a belt conveyor; Fixed brackets installed on both sides of the belt conveyor; A push rod mounted on a fixed bracket, one end of which is connected to a cylinder; Guide unit connected to the push rod; Photoelectric switches used for sensing tobacco leaves; The cylinder and the photoelectric switch form a circuit. When the tobacco passes the photoelectric switch, the photoelectric switch closes, and the circuit is turned on, driving the push rod to push the guide unit to straighten the tobacco.

[0006] Furthermore, the push rods are configured as two and symmetrically arranged on the fixed bracket.

[0007] Furthermore, the guiding unit is an adjustable plate-like structure.

[0008] Furthermore, the guide unit is made of 304 stainless steel.

[0009] Furthermore, the sensing position of the photoelectric switch is adjustable.

[0010] Furthermore, one end of the cylinder is provided with a quick-connect interface, and the cylinder is connected to a compressed air pipe through the quick-connect connector.

[0011] Furthermore, an adjusting nut is provided at the bottom of the cylinder, and the cylinder adjusts its position by adjusting the adjusting nut.

[0012] Furthermore, pressure strips are provided on both sides of the belt conveyor, and side baffles are connected to the belt conveyor through the pressure strips.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This invention features fixed supports on both sides of a belt conveyor, with push rods and cylinders mounted on the supports. A guide unit is connected to the push rods, and a photoelectric switch detects the position of the tobacco flakes and outputs a signal to control the cylinder's action. When the tobacco flakes deviate from their designated position, the cylinder automatically drives the push rod to push the guide unit to correct the tobacco flakes, thus achieving automatic alignment of the tobacco flakes during the conveying process. This effectively prevents the tobacco flakes from skewing during belt conveyor transport, ensuring that the tobacco flakes are centered when entering the secondary forking device, improving the stability of the distribution and the continuity of the tobacco production line. It also has the advantages of simple structure and high degree of automation. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Reference Figure 1The present invention provides a conveyor belt tobacco straightening device, including a conveyor belt and straightening mechanisms arranged on both sides of the conveyor belt; the straightening mechanism includes a fixed bracket, a push rod 1, a cylinder 6, and a guide unit 2; the fixed bracket is installed on both sides of the conveyor belt and is used to support and fix the push rod 1 and the cylinder 6 assembly.

[0019] The push rod 1 is mounted on a fixed bracket and is used to transmit the linear reciprocating motion of the cylinder 6 to the guide unit 2 to realize the pushing and straightening action of the tobacco. There are two push rods 1, which are symmetrically mounted on the fixed bracket, so as to symmetrically correct the tobacco on both sides of the belt conveyor and improve the alignment accuracy.

[0020] like Figure 2 As shown, the cylinder 6 is a pneumatic component, with one end mounted on a fixed bracket via a connector, and the other end connected to the push rod 1. The piston rod of the cylinder 6 extends and retracts, causing the push rod 1 to reciprocate, thereby pushing the guide unit 2 to align the tobacco leaves. An adjusting nut 8 is provided at the bottom of the cylinder 6, which can be used to finely adjust the position of the cylinder 6 to align it with the center line of the belt conveyor.

[0021] The cylinder 6 is connected to the compressed air pipe via a quick-connect fitting 7. It should be noted that the compressed air pipe can be an existing product and can be used in conjunction with an air source device to provide driving force for the cylinder 6. This embodiment does not further limit the compressed air pipe.

[0022] The guide unit 2 is connected to the push rod 1. The guide unit 2 is a long plate-shaped structure. Its position is flush with the conveyor belt direction. The guide unit 2 moves along the width direction of the conveyor belt under the drive of the cylinder 6 and directly contacts the tobacco to adjust its position.

[0023] Specifically, the guide unit 2 is configured as an adjustable structure, and its angle or position can be changed by the adjustment mechanism to adapt to the conveying path of different specifications of tobacco sheets; in this embodiment, the guide unit 2 is configured as a bent plate-like structure, wherein the bending point can be adjusted by a fixed rotating shaft structure; the guide unit 2 is made of 304 stainless steel, which has good strength and wear resistance, ensuring reliability for long-term use.

[0024] The photoelectric switch is installed at a suitable position on the belt conveyor to detect whether the tobacco leaves deviate from the conveying center. In this embodiment, the photoelectric switch is set at the initial end of the guide unit 2, that is, the starting position of the belt conveyor's rotation direction. When the tobacco leaves move on the belt conveyor, through a circuit connected to the cylinder 6, the photoelectric switch can promptly capture the position of the tobacco leaves as they pass by, thereby closing the circuit and transmitting a signal to the solenoid valve. It should be noted that existing equipment can be used for the photoelectric switch. When the tobacco leaves pass through the sensing area of ​​the photoelectric switch, the photoelectric switch outputs an electrical signal to the control circuit. This signal controls the solenoid valve to open and close, thereby driving the cylinder 6 to actuate. The cylinder 6 pushes the push rod 1 and the guide unit 2 to correct the deviated tobacco leaves. The sensing position of the photoelectric switch is adjustable to adapt to different conveying speeds and tobacco leaf specifications.

[0025] In addition, pressure strips 5 and side baffles 3 are provided on both sides of the belt conveyor. The pressure strips 5 are devices for pressing the skirt of the belt conveyor and are used to fix the side baffles 3 and maintain the stability of the conveyor path. The side baffles 3 are installed on the outside of the pressure strips 5 to prevent the tobacco flakes from falling off or shifting during the conveying process, and further ensure the stable transmission of the tobacco flakes on the belt 4.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
