Description

Technical Field

[0001] The utility model relates to cigar packaging equipment, and more specifically, to a stepped tube pushing mechanism for a cigar packaging tube. Background Art

[0002] Cigars are a type of tobacco product made from dried and fermented tobacco. When smoking, one end is ignited and the other end is inhaled to produce smoke. Cigars are loved by smokers for their unique taste. In order to facilitate storage, transportation, subsequent fermentation and sale, cigarette companies will package cigars after making them into finished products. Common packaging methods are mainly box packaging and single-piece packaging. For example, the Chinese utility model patent document CN221554698U discloses an umbrella-type pull-out cigar box, which uses a box body as a container and fixes the cigars through partition grooves to achieve packaging of cigars. Single-piece packaging mainly adopts tube packaging, that is, the cigars are packaged in a packaging tube. The packaging tube is a hollow tube with an opening at one end and a closed end at the other end. The open end is sealed with a cover plug, and the cover plug and the packaging tube are connected. Generally, threaded connections or snap connections are used; relatively high-end cigars are often packaged in single-tube packaging tubes. Single-tube packaging can effectively protect the cigar wrapper and cigar foot from physical damage, while providing a better fermentation environment, preventing moisture evaporation in the cigar, helping the cigar maintain a long-lasting aroma, and improving the quality of the cigar. Cigars packaged in single tubes are also more convenient to carry and can be placed in a pocket at will, making them suitable for smoking when going out; the conveyor belt of existing single-tube cigar packaging equipment adopts an intermittent motion mode, and the cigars and packaging tubes are placed on the conveyor belt by an automatic blanking mechanism, and then the packaging tube is pushed by a tube pushing device to put the cigars into the packaging tube. The subsequent cap plug unloading mechanism places the cap plug on the conveyor belt, and finally the cap plug is clamped on the packaging tube by a cap pressing and rotating device, thereby completing the single cigar packaging. When the tube-pushing device is inserting cigars into the packaging tube, a cylinder with a long stroke is required to completely insert the cigars into the packaging tube at one time. The conveyor belt has to wait until the tube-pushing device completes its operation before it can continue to move. The other components are also unable to perform subsequent operations. The equipment's production efficiency is low and cannot meet the company's efficient production needs. Utility Model Content

[0003] The utility model overcomes the shortcomings of the prior art and provides an implementation method of a stepped tube pushing mechanism for cigar packaging tubes, in the hope of solving the problem of low production efficiency of the entire packaging production line caused by the long stroke of the cylinder of the tube pushing device of the existing single-cigar packaging equipment.

[0004] In order to solve the above technical problems, one embodiment of the present invention adopts the following technical solutions:

[0005] A stepped tube pushing mechanism for cigar packaging tubes is installed on the upper part of a roller conveyor. The roller conveyor uses intermittent motion to control the operation of the conveyor belt. A plurality of limit grooves are longitudinally arranged on the conveyor belt. The stepped tube pushing mechanism includes a stepped push plate. A plurality of steps are evenly arranged at the front end of the stepped push plate, and the steps grow evenly from the incoming material end of the roller conveyor. The lower surface of the stepped push plate is close to the upper surface of the conveyor belt. The stepped push plate can reciprocate in a position parallel to the upper surface of the conveyor belt and perpendicular to the conveying direction of the conveyor belt.

[0006] Optional: The step tube pushing mechanism also includes a tube pushing cylinder, the cylinder shaft of the tube pushing cylinder is fixedly connected to the rear end of the step push plate, and the cylinder body of the tube pushing cylinder is fixedly connected to the bracket of the roller conveyor.

[0007] Optionally, the stepped tube pushing mechanism for the cigar packaging tube has a limiting frame, and both ends of the limiting frame are fixedly connected to the brackets on both sides of the conveyor belt of the roller conveyor.

[0008] Optional: The stepped push plate has five steps.

[0009] Optionally, an automatic blanking mechanism is further provided at the front of the stepped pipe pushing mechanism on the roller conveyor.

[0010] Optionally, the roller conveyor includes a bracket, a chain, and a roller. The chain is rotatably mounted on the bracket, and a plurality of rollers are uniformly and longitudinally fixedly mounted on the chain, with a limit groove formed between adjacent rollers. The roller conveyor also has a drive motor.

[0011] Compared with the prior art, the present invention has at least the following beneficial effects: the present invention pushes the packaging tube multiple times step by step through the steps of the stepped push plate, thereby completing the process of inserting cigars into the packaging tube. The stepped push plate with five steps can push four packaging tubes at the same time to insert cigars. Compared with the prior art, the present invention shortens the stroke of the cylinder of the tube pushing device through multiple steps of pushing, reduces the time it takes for the tube pushing device to push the packaging tube, improves work efficiency, and ensures the production efficiency of the factory.

[0015] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] like Figure 1 、 Figure 2 As shown: a stepped tube pushing mechanism for cigar packaging tubes, the stepped tube pushing mechanism 2 is installed at the rear of the automatic blanking mechanism 1 on the roller conveyor 6, and the roller conveyor 6 adopts intermittent motion to convey materials. The roller conveyor 6 includes a bracket 602, a chain, a roller 603, and a driving motor. The chain is rotatably installed on the bracket 602, and a plurality of rollers 603 are evenly and longitudinally fixedly installed on the chain. The chain and the roller 603 are combined to form a conveyor belt. A longitudinally arranged limit groove 601 is formed between two adjacent rollers 603. The chain is rotated by the driving motor, and the chain rotation drives the roller 603 to move. The longitudinally arranged limit groove 601 refers to the conveying direction of the conveyor belt of the roller conveyor 6 as the transverse direction, and the direction in the same horizontal plane as the conveyor belt and perpendicular to the transverse direction as the longitudinal direction, that is, each limit groove 601 is arranged on the conveyor belt plane perpendicular to the conveying direction of the conveyor belt.

[0017] The stepped tube pushing mechanism 2 includes a tube pushing cylinder 3, a limiting frame 4, and a stepped push plate 5. The tube pushing cylinder 3 is a reciprocating cylinder, and its cylinder body is fixedly connected to the bracket 602 of the roller conveyor 6. The stroke of the cylinder shaft of the tube pushing cylinder 3 is parallel to the upper surface of the conveyor belt of the roller conveyor 6 and perpendicular to the conveying direction of the conveyor belt. The rear part of the stepped push plate 5 is fixedly connected to the cylinder shaft of the tube pushing cylinder 3. The telescopic movement of the tube pushing cylinder 3 drives the stepped push plate 5 to reciprocate to push the packaging tube. The front end of the stepped push plate 5 has multiple steps evenly arranged, and the steps are evenly increased from the incoming end of the roller conveyor 6. The bottom of the stepped push plate 5 is close to the upper surface of the roller 603. The preferred stepped push plate 5 has five steps. The cigars are put into the packaging tubes step by step through the multiple steps of the stepped push plate 5. There are two limit frames 4, which span above the roller conveyor. The two ends of the limit frame 4 are respectively connected to the brackets 60 on both sides of the conveyor belt of the roller conveyor 6 When the cylinder shaft of the tube-pushing cylinder 3 is in the retracted state, the lowest step of the stepped pushing plate 5 abuts against the closed end of the packaging tube; when the cylinder shaft of the tube-pushing cylinder 3 is extended, the stepped pushing plate 5 is pushed toward one end of the limiting groove 601. During the movement, one of the steps of the stepped pushing plate 5 abuts against the closed end of the packaging tube, and the packaging tube is axially pushed along the limiting groove 601, so that the open end of the packaging tube gradually moves toward the side of the cigar. After each reciprocating movement of the tube-pushing cylinder 3, the conveyor belt of the roller conveyor 6 drives the cigar and the packaging tube to move intermittently toward the discharge port. After the conveyor belt moves intermittently many times, the steps of the stepped pushing plate 5 push the packaging tube step by step for many times, and the packaging tube puts the cigar in the corresponding limiting groove 601 into its tube body; four packaging tubes can be pushed simultaneously to set the cigars through the five steps of the stepped pushing plate 5.

[0018] Specific usage: Before use, place cigars and packaging tubes in the automatic blanking mechanism 1 respectively. When in use, the automatic blanking mechanism 1 drops the packaging tubes and cigars from its discharge port into the same limiting groove 601 on the conveyor belt below. After the cigars and packaging tubes are in place, the roller conveyor 6 drives the packaging tubes and cigars to move intermittently toward the step tube pushing mechanism 2. When the intermittent movement reaches the position of the step tube pushing mechanism 2, the cylinder shaft of the tube pushing cylinder 3 extends, and the lowest step of the step pushing plate 5 abuts against the closed end of the packaging tube. Next, the tube-pushing cylinder 3 pushes the packaging tube axially along the limiting groove 601. After each reciprocating motion of the tube-pushing cylinder 3, the conveyor belt of the roller conveyor 6 drives the cigars and the packaging tube to intermittently move toward the discharge port. The steps of the stepped push plate 5 push the packaging tube step by step for multiple times to insert the cigars in the corresponding limiting groove 601 into its tube body; the roller conveyor 6 continues to move intermittently, and the packaging tube with the cigars is transported to the rear cover plug clamping process, and the opening of the packaging tube is sealed through the cover plug clamping process.

[0019] Although the present invention has been described herein with reference to illustrative embodiments thereof, it will be understood that those skilled in the art may devise numerous other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, within the scope disclosed herein, various variations and improvements may be made to the components and / or layout of the subject combination arrangement. In addition to variations and improvements to the components and / or layout, other uses will also be apparent to those skilled in the art.
