Description

Technical Field

[0001] The present application relates to the technical field of cigarette factory packaging, and in particular to a device for uniformly separating continuous cigarette rods longitudinally. Background Art

[0002] When a cigarette factory is packing cigarette rods, the continuously arranged cigarette rods are transported to a case filling and sealing machine by a conveyor belt, where the cigarette rods are packed. Appearance inspection devices and code scanning inspection devices are also arranged along the conveyor belt to inspect the cigarette rods. Defective cigarette rods are detected to be discarded. During the above-mentioned appearance inspection and code scanning inspection of the cigarette rods, since the cigarette rods on the conveyor belt are continuously arranged, the front and rear cigarette rods are closely adjacent, so that the interval between the cigarette rods is too short. There is a hidden danger of insufficient response time for the appearance inspection device and the code scanning inspection device, which makes it easy for the appearance inspection device and the code scanning inspection device to miss inspections, which can easily lead to production quality accidents. Utility Model Content

BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 This is a schematic diagram of the structure of the longitudinal uniform separation device provided in an embodiment of the present application. DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0021] like Figure 1 As shown, an embodiment of the present application provides a longitudinal uniform separation device for continuous cigarette rods, which is used to process the cigarette rods conveyed before packing. The cigarette rods to be packaged are conveyed to a cartoning machine via a conveyor belt for packing. Various detection devices are also arranged along the conveyor belt to detect the cigarette rods so as to remove defective cigarette rods. Since the cigarette rods are continuously arranged front and back on the conveyor belt, the front and rear cigarette rods are adjacent to each other. When the detection device performs detection, due to the limitation of the detection response time of the detection equipment, the problem of missing the detection of cigarette rods may occur, which may easily lead to production quality accidents. The longitudinal uniform separation device of the present application is intended to separate the continuous and adjacently arranged cigarette rods front and back, so that there is a sufficient distance between the front and rear cigarette rods. The separated cigarette rods are then detected by the detection device to improve the accuracy of the detection device.

[0022] The longitudinal uniform separation device comprises a bracket 100, on which a first contact piece 21 and a second contact piece 22 are arranged. Along the conveying direction of the conveyor belt, the bracket 100 is arranged upstream of the detection device. A gap is formed between the first contact piece 21 and the second contact piece 22 for the cigarette rod to pass through. The first contact piece 21 and the second contact piece 22 are used to contact each other on both sides of the cigarette rod, so as to apply resistance to the forward movement of the cigarette rod, so that the forward speed of the continuously arranged cigarette rods on the conveyor belt is reduced when passing through the first contact piece 21 and the second contact piece 22, thereby separating the continuously arranged cigarette rods one by one, so that there is a sufficient gap between the front and rear adjacent cigarette rods, and preventing the detection device from missing detection. In order to avoid production quality accidents, the first contact piece 21 and the second contact piece 22 can be adjusted in position on the bracket 100. The first contact piece 21 can be adjusted in a direction away from or close to the second contact piece 22, and the second contact piece 22 can be adjusted in a direction away from or close to the first contact piece 21, so that the spacing between the first contact piece 21 and the second contact piece 22 can be adjusted, and the size of the forward obstruction force on the tobacco rod can be adjusted, and the deceleration effect of the tobacco rod can be adjusted. Therefore, the size of the spacing between the tobacco rods after obstruction can be adjusted, which can be adjusted according to actual production needs, and tobacco rods of different specifications can be processed, thereby improving the applicability of the longitudinal uniform separation device.

[0023] Preferably, the first contact member 21 includes a first roller, and the second contact member 22 includes a second roller. The outer periphery of the first roller and the outer periphery of the second roller are used to contact the two sides of the tobacco rod. After being installed by the bracket 100, the first roller and the second roller are respectively located on the two sides of the conveyor belt, so as to respectively contact the two sides of the horizontal tobacco rod. The outer periphery of the roller structure is smoother and will not damage the appearance of the tobacco rod. The first roller and the second roller can be unpowered rotatable roller structures, and the tobacco rod is decelerated by rolling friction. Preferably, the first roller and the tobacco rod are in contact by sliding friction, and the second roller and the tobacco rod are also in contact by sliding friction. In this embodiment, a driving device is also included. Under the drive of the driving device, the first roller and the second roller can both rotate, and the rotation directions of the first roller and the second roller are opposite. In other words, the rotation directions of the outer peripheral sides of the first roller and the second roller that are close to each other are the same, that is, the rotation direction of the outer peripheral side of the first roller in contact with the tobacco rod is the same as the rotation direction of the outer peripheral side of the second roller in contact with the tobacco rod, and the rotation direction is opposite to the moving direction of the tobacco rod, so that the tobacco rod is limited by sliding friction. In this embodiment, when the tobacco rod and the first roller and the second roller are in contact with each other, a relative movement in the opposite direction of movement is instantly generated at the contact point, which can more smoothly enter the state of sliding friction and achieve a state of more stable restriction and deceleration of the tobacco rod. Moreover, in this embodiment, the above-mentioned rotation direction is the normal operating mode of the first roller and the second roller. When the tobacco rod is stuck between the first roller and the second roller, the first roller and the second roller are controlled to reverse by the driving device, so that the tobacco rod can be discharged forward smoothly, and obstacle clearing is more convenient.
