Description

Technical Field

[0001] The utility model relates to the technical field of cigarette carton sorting and packaging, in particular to a paddle for cigarette carton sorting and packaging. Background Art

[0002] In the sorting and packing equipment for cigarette factories, the cigarette pile sorting bin is used to stack cigarette rods. The bottom of the cigarette pile sorting bin is set as follows: Figure 4 The chain-driven device (i.e., a paddle set on the chain) shown in the figure moves the paddle with the chain to pry out the cigarettes in the cigarette sorting bin and send them to the conveyor belt for convenient packaging and delivery. However, in actual sorting, in order to prevent the cigarette box from being pulled out and scratched, the thickness of the paddle and the friction coefficient of the surface are designed according to the material characteristics of different cigarette boxes. Therefore, when a cigarette sorting bin needs to change the type of cigarette, the paddle also needs to be replaced. The existing paddle is directly fixed on the chain plate of the chain. When replacing the paddle, the chain needs to be removed to facilitate the replacement of the paddle on the chain, which is inefficient and difficult to replace. Utility Model Content

[0003] The purpose of the utility model is to provide a paddle for sorting and packing cigarettes, which is convenient for installation and disassembly.

[0004] In order to solve the deficiencies of the above-mentioned technical problems, the utility model adopts the following technical solution: a paddle for sorting and packing cigarettes, comprising a paddle body and two clamping blocks, a groove being provided on the lower end surface of the paddle body, a horizontally rotating transmission rod being provided in the groove, one end of the transmission rod passing through the outside of the paddle body, a rod body of the transmission rod located in the groove being provided with two opposite sections of threads, the upper parts of the two clamping blocks being screwed one by one on the two sections of the threaded rod body of the transmission rod and being non-rotatable, opposite rounded rectangular holes being provided on opposite sides of the two clamping blocks, and the rounded rectangular holes being located outside the groove.

[0005] As a further optimization of the paddle for sorting and packing cigarettes of the utility model, the rounded rectangular hole is a blind hole.

[0006] As a further optimization of the paddle for sorting and packing cigarettes of the utility model, the clamping block is T-shaped, the vertical portion of the clamping block is screwed on the transmission rod, and the rounded rectangular hole is opened in the horizontal portion of the clamping block.

[0007] As a further optimization of the paddle for sorting and packing cigarettes of the utility model, the horizontal portion of the clamping block is a rounded rectangle.

[0008] As a further optimization of the paddle for sorting and packing cigarettes of the utility model, the two sides of the vertical portion slide in contact with the inner sides of the groove.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] Example 1

[0020] like Figure 1-3As shown, this embodiment provides a paddle for sorting and packaging cigarette cartons. The paddle can be quickly installed and removed from the chain, making it convenient for workers to replace the paddle on the chain. The paddle provided in this embodiment includes a paddle body 1 and two clamping blocks 2 made of aluminum alloy. The two clamping blocks 2 are arranged side by side on the lower end surface of the paddle body 1 and can move relative to or away from each other. By controlling the relative movement of the two clamping blocks 2, the spacing between them is changed. The clamping blocks 2 clamp the outer link plates on the chain, thereby fixing the paddle body 1 to the chain.

[0021] In this embodiment, a groove 5 is formed on the lower end surface of the paddle body 1. A horizontally rotating transmission rod 3 is mounted in the groove 5. One end of the transmission rod 3 extends outside the paddle body 1. The transmission rod 3, located within the groove 5, has two oppositely threaded sections. The upper portions of the two clamping blocks 2 are screwed onto the two threaded sections of the transmission rod 3 and cannot rotate. Rotating the transmission rod 3 moves the two clamping blocks 2 on its body. Because the two threads are oppositely threaded, the two clamping blocks 2 can be moved toward or away from each other, thereby changing the spacing between the two clamping blocks 2. This allows the two clamping blocks 2 to clamp the chain, securing the paddle block to the chain.

[0022] In this embodiment, opposite sides of the two clamping blocks 2 are provided with opposing rounded rectangular holes 7, which are located outside the groove 5. The rounded rectangular holes 7 provided on the clamping blocks 2 are consistent with the shape of the outer link plates of the chain. By positioning the outer link plates of the chain within the rounded rectangular holes 7 during the clamping process, the position of the shifting blocks is further restricted, preventing them from falling off the chain.

[0023] In this embodiment, the clamping block 2 is T-shaped, the vertical portion 201 of the clamping block 2 is screwed onto the transmission rod 3 , and the rounded rectangular hole 7 is provided in the horizontal portion 202 of the clamping block 2 .

[0024] In this embodiment, the horizontal portion 202 of the clamping block 2 is a rounded rectangular shape. Because the gap between the chain plates is not very large, the horizontal portion 202 is conveniently inserted between the chain plates without interfering with the position changes of the chain plates. Therefore, the horizontal portion 202 of the clamping block 2 is a rounded rectangular shape, which is more suitable for the change of the gap between the chain plates.

[0025] In this embodiment, two structures are employed to prevent the clamping block 2 from rotating when threaded with the transmission rod 3. One is to have the sides of the vertical portion 201 slide in contact with the inner sides of the groove 5. This contact prevents the clamping block 2 from rotating. The other is to have two limiting rods 6 disposed within the groove 5, parallel to the lead screw. The ends of the limiting rods 6 are fixedly connected to the inner sides of the groove 5. The vertical portion 201 of the clamping block 2 slides over the limiting rods 6. The limiting rods 6 cooperate with the transmission rod 3 to limit the rotation of the clamping block 2.

[0026] In this embodiment, the end of the transmission rod 3 outside the plectrum body 1 is provided with a twist handle 4. The setting of the twist handle 4 is convenient for the staff to control the rotation of the transmission rod 3. At the same time, the outer circumference of the twist handle 4 should be provided with anti-slip lines to facilitate the staff to twist.

[0027] Example 2

[0028] like Figure 4 As shown, this embodiment provides a paddle for sorting and packing cigarette cartons. This paddle shares most of its structure with the paddle of Embodiment 1, differing in that the rounded rectangular hole 7 in this embodiment is a blind hole. The provision of the blind hole provides a sidewall on the horizontal portion 202 of the clamping block 2, which enhances the strength of the horizontal portion 202.

[0029] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art may make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
