Description

Technical Field

[0001] This invention relates to the technical field of packaging equipment for cigarettes using the YB45 packaging machine, and more specifically, to a device for reducing the damage to the inner lining paper caused by the first wheel of the YB45 packaging machine. Background Technology

[0002] Currently, the YB45 packaging machine's cigarette pack forming system in tobacco manufacturing enterprises includes various components and mechanisms for folding the inner lining paper, folding the label paper, and rejecting substandard cigarette packs. It mainly consists of rollers 1, 2, 3, and 4, as well as a cigarette pack lifting and pushing mechanism. Roller 1 completes the shaping and conveying of the cigarette packs. During cigarette pack transfer, roller 1 first opens its grippers to allow 20 cigarettes to enter, then closes. Roller 1 rotates 180 degrees, transferring the cigarettes to the entrance of roller 2. Then, the grippers open, and the 20 cigarette packs are pushed into the groove of roller 2. The inner lining paper, after being cut into individual sheets, is located between rollers 1 and 2. The 20 cigarette packs push the inner lining paper together into roller 2, completing the partial folding of the inner lining paper. The original roller 1's gripper baffle was a straight steel plate, mainly used to protect the cigarettes from being thrown out during rotation. During the rotation and opening process of the gripper, the end of the baffle is prone to wear when it comes into contact with the inner lining paper, which can cause scratches, tears, or even blockage of the inner lining paper at the second wheel, affecting product quality. Summary of the Invention

[0003] The purpose of this invention is to provide a device for reducing the damage to the inner lining paper caused by the first wheel of a YB45 packaging machine.

[0004] The present invention provides a device for reducing the tearing of inner lining paper by the first wheel of a YB45 packaging machine, comprising:

[0005] Wheel 1; Two gripper groups are symmetrically arranged on wheel 1, each gripper group consisting of a left gripper and a right gripper;

[0006] The left gripper, the rear end of which is rotatably connected to the first wheel;

[0007] The right gripper, the rear end of which is rotatably connected to the first wheel;

[0008] The front ends of the left and right grippers clamp or open relative to the midline between the left and right grippers.

[0009] The front end of the left gripper is provided with a left baffle, and the left baffle is provided with an arc, a chamfer, or a rounded corner on the side near the center line;

[0010] The front end of the right gripper is provided with a right baffle, and the right baffle is provided with an arc, a chamfer, or a rounded corner on the side near the center line;

[0011] Furthermore, when the left and right grippers are clamped, there is a gap between the left and right baffles that is smaller than the diameter of the cigarette; during the opening process of the left and right grippers, the running trajectories of the left and right baffles do not interfere with the inner lining paper.

[0012] Furthermore, the first wheel can drive the left gripper and the right gripper to rotate in a circular motion.

[0013] Optionally, the first wheel can drive the left gripper and the right gripper to switch between a first position and a second position.

[0014] Furthermore, the first position is located at the smoke storage tank.

[0015] Furthermore, the second position is located at the entrance of the second wheel.

[0016] Furthermore, the inner lining paper was cut into individual sheets and placed at the entrance of wheel number two.

[0017] Furthermore, the length of the arc is not less than half the total length of the left baffle.

[0018] Furthermore, the length of the arc is not less than half the total length of the right baffle.

[0019] Furthermore, the chamfer is not less than 10 degrees.

[0020] Furthermore, the left baffle and the right baffle have the same structure. The inner surface of the baffle is a plane, and the outer surface of the baffle is an arc-shaped surface. The highest point of the arc-shaped surface of the outer surface of the baffle does not coincide with the cross section of the baffle passing through the midpoint. The highest point is located on the side of the baffle close to the gripper.

[0021] According to the technical content disclosed in this invention, the following beneficial effects are achieved:

[0022] This invention provides a device to reduce the damage to the inner lining paper caused by the first wheel of a YB45 packaging machine. The end faces of the left and right baffles are set as arcs, chamfers, or rounded corners to ensure that the left and right grippers do not interfere with the inner lining paper when they are open, thus preventing the inner lining paper from being damaged.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0033] like Figure 1 and Figure 2 As shown, according to the present invention, a device for reducing the damage to the inner lining paper caused by the first wheel of a YB45 packaging machine is provided. This device includes:

[0034] Wheel 1; Two gripper groups are symmetrically arranged on wheel 1, each gripper group consisting of a left gripper and a right gripper;

[0035] Left gripper 2, the rear end of left gripper 2 is rotatably connected to wheel 3;

[0036] Right gripper 1, the rear end of right gripper 1 is rotatably connected to wheel 3;

[0037] The front ends of the left gripper 2 and the front ends of the right gripper 1 clamp or open relative to the midline between the left gripper 2 and the right gripper 1.

[0038] The front end of the left gripper 2 is provided with a left baffle 9, and the side of the left baffle 9 near the center line is set as an arc, or a chamfer, or a rounded corner;

[0039] The front end of the right gripper 1 is provided with a right baffle 6, which is set as an arc, chamfer, or rounded corner on the side near the center line.

[0040] This invention provides a device to reduce the damage to the inner lining paper caused by the first wheel of a YB45 packaging machine. The end faces of the left baffle 9 and the right baffle 6 are set as arcs, chamfers, or rounded corners to ensure that the left gripper 2 and the right gripper 1 do not interfere with the inner lining paper 5 when they are open, thus preventing the inner lining paper 5 from being damaged.

[0041] During the rotation of wheel 3 around the central axis, the maximum trajectory 8 of the entire wheel body is shown in the figure, and it does not interfere with the inner lining paper 5. When the left gripper 2 and the right gripper 1 open, the maximum rotation trajectory 7 of the baffle is shown in the figure. When the left gripper 2 and the right gripper 1 open, they will not interfere with the inner lining paper 5, thus preventing the inner lining paper 5 from being torn.

[0042] Furthermore, wheel 3 can drive the left gripper 2 and the right gripper 1 to rotate in a circular motion.

[0043] Furthermore, wheel 3 can drive the left gripper 2 and the right gripper 1 to switch between the first and second positions.

[0044] Furthermore, the first location is at the smoke storage trough 4.

[0045] Furthermore, the second position is located at the entrance of the second wheel.

[0046] Details:

[0047] When the first wheel 3 is transferring cigarettes, the left jaw 2 and the right jaw 1 are in the first position, located at the cigarette storage trough 4. First, the left jaw 2 and the right jaw 1 open to allow 20 cigarettes placed in the cigarette storage trough 4 to enter, and then clamp them. The first wheel 3 rotates 180 degrees, causing the left jaw 2 and the right jaw 1 to rotate to the second position, located at the entrance of the second wheel.

[0048] The cigarettes are passed to the entrance of the second wheel, then the left gripper 2 and right gripper 1 open, pushing the 20-cigarette pack into the groove of the second wheel. The inner liner paper 5, after being cut into individual sheets, is positioned between the first wheel 3 and the second wheel, i.e., at the entrance of the second wheel. The 20-cigarette pack pushes the inner liner paper 5 into the second wheel together, completing a partial fold of the inner liner paper 5.

[0049] Optionally, the arc length should be no less than half the total length of the left baffle 9. The arc length should be no less than half the total length of the right baffle 6. This dimensional setting can better prevent the inner lining paper 5 from being torn.

[0050] Optional, the chamfer should be no less than 10 degrees. This size setting better prevents the inner lining paper from being torn.

[0051] The left baffle and the right baffle have the same structure. The inner surface of the baffle is flat, and the outer surface of the baffle is curved. The highest point of the curved surface of the outer surface of the baffle does not coincide with the cross section of the baffle passing through the midpoint. The highest point is located on the side of the baffle close to the gripper.

[0052] In summary, the present invention provides a device to reduce the damage of the inner lining paper by the first wheel of the YB45 packaging machine. The end faces of the left baffle 9 and the right baffle 6 are set as arcs, chamfers, or rounded corners to ensure that the left gripper 2 and the right gripper 1 do not interfere with the inner lining paper 5 when they are open, thus preventing the inner lining paper 5 from being damaged.

[0053] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of the invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention.
