Description

Technical Field

[0001] This utility model relates to cigar packaging equipment, and more specifically, to a capping and feeding mechanism for cigar packaging tubes. Background Technology

[0002] A cigar is a tobacco product made from dried and fermented tobacco. When smoking, one end is lit, and the other end is inhaled to produce smoke. Its unique taste is appreciated by smokers. To facilitate storage, transportation, further fermentation, and sale, cigarette manufacturers package cigars after production. Common packaging methods include boxes and single-cigar packs. For example, Chinese utility model patent CN221554698U discloses an umbrella-style pull-out cigar box, which uses the box body as a container and secures the cigars with partitions. Single-cigar packs mainly use tubular packaging, where the cigar is packaged in a hollow tube with an opening at one end and a closed end at the other. The opening end is sealed with a cap, which is typically connected to the tube by threads or snaps. Relatively high-end cigars... Cigars are often packaged individually using packaging tubes. This single-tube packaging effectively protects the wrapper and stem of the cigar from physical damage, while providing a better fermentation environment, preventing moisture evaporation, helping the cigar maintain its aroma, and improving its quality. Single-tube cigars are also more portable, easily placed in a pocket, making them suitable for smoking on the go. Current single-cigar packaging equipment uses an intermittent conveyor belt. An automatic feeding mechanism places the cigar and packaging tube onto the conveyor belt, then a pushing device pushes the packaging tube to insert the cigar. A capping mechanism then places the cap onto the conveyor belt, and finally, a capping device secures the cap to the packaging tube, completing the single-cigar packaging. In actual production, controlling the opening and closing of the capping mechanism's outlet to ensure the cap falls smoothly, evenly, and correctly onto the conveyor belt is crucial. Utility Model Content

[0003] This invention overcomes the shortcomings of the prior art and provides an embodiment of a cap feeding mechanism for cigar packaging tubes, which is expected to solve the problem of how the cap falls onto the conveyor belt at a uniform speed and in the correct posture.

[0004] To solve the above-mentioned technical problems, one embodiment of this utility model adopts the following technical solution:

[0005] A capping mechanism for cigar packaging tubes includes a vibratory feeder, a feeding track, and a cap-separating mechanism. One end of the feeding track is disposed below the discharge port of the vibratory feeder without contact, and the discharge port of the feeding track corresponds to the capping section of the roller conveyor belt. The cap-separating mechanism includes a cap-separating cylinder, a cap-separating gripper, and a cap-separating baffle. The cap-separating cylinder is fixedly installed on one side of the feeding track. Two cap-separating grippers are rotatably mounted on the lower part of the cap-separating cylinder via a rotating shaft. The bottom of each cap-separating gripper is fixedly mounted with a cap-separating baffle. The cap-separating cylinder can control the rotation of the cap-separating grippers to control the opening and closing of the discharge port of the feeding track.

[0006] Optionally: The cap-separating gripper has a "Z" shaped structure and the two cap-separating grippers are arranged in mirror image opposite each other, with the upper end of the cap-separating gripper rotatably connected to the lower part of the cap-separating cylinder.

[0007] Optionally: the two cover-separating grippers have a rotational clearance at their adjacent ends, the rotational clearance corresponding vertically to the cylinder shaft of the cover-separating cylinder, and the rotational clearance is smaller than the diameter of the cylinder shaft.

[0008] Optionally: The two cap-separating grippers are respectively provided with semi-circular toothed discs facing each other at their near ends, and a rack is connected to the cylinder shaft of the cap-separating cylinder, the rack meshing with the semi-circular toothed discs on the cap-separating grippers.

[0009] Optional: The vibratory feeder is fixedly mounted on a grounding bracket, and the vibratory feeder does not come into contact with the roller conveyor.

[0010] Optionally, the feeding track is trough-shaped or frame-shaped.

[0011] Optional: The feeding track includes an inclined section and a vertical section, which are connected. The end of the inclined section near the vibratory plate is higher than the other end.

[0012] Optionally, the roller conveyor includes a support frame, a chain, and rollers. The chain is rotatably mounted on the support frame, and multiple rollers are evenly and longitudinally fixedly mounted on the chain. Longitudinal limiting grooves are formed between adjacent rollers. The roller conveyor also includes a drive motor.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0020] like Figure 1 As shown: a capping and feeding mechanism for a cigar packaging tube. The discharge port of the capping and feeding mechanism 3 corresponds to the capping and feeding section on the conveyor belt of the roller conveyor 1. The roller conveyor 1 uses an intermittent motion to transport materials. The intermittent motion refers to the intermittent conveying mode of the conveyor belt of the roller conveyor 1, which moves and stops intermittently. During the interval between stops, each mechanism performs its work, and during the conveying process, each mechanism stops its work, thereby ensuring that each mechanism can operate smoothly. The roller conveyor 1 includes a support 101, a chain, rollers 102, and a drive motor. The chain is rotatably mounted on the support 101, and multiple rollers 102 are evenly and longitudinally fixedly mounted on the chain. The chain and rollers 102 combine to form a conveyor belt. A longitudinally arranged limiting groove 2 is formed between two adjacent rollers 102. The chain is driven by the drive motor to rotate, and the rotation of the chain drives the rollers 102 to move. The longitudinally arranged limiting groove 2 refers to a groove that is horizontally oriented with the conveyor belt of the roller conveyor 1 and vertically oriented with the same horizontal plane as the conveyor belt and perpendicular to the horizontal direction. That is, each limiting groove 2 is set on the plane of the conveyor belt perpendicular to the conveyor belt's transmission direction. The feed end of the roller conveyor 1 is connected to the front-end single cigar packaging equipment. After the front-end packaging equipment inserts the cigar into the packaging tube, the packaging tube containing the cigar is conveyed to the limiting groove 2 on the roller conveyor 1. The side of the conveyor belt where the packaging tube is placed is the packaging tube section, and the other side is the capping section.

[0021] like Figure 1As shown: The capping and feeding mechanism 3 includes a vibratory feeder 302, a feeding track 301, and a cap-separating mechanism 303. The vibratory feeder 302 is mounted on a grounding bracket and does not contact the roller conveyor 1. The vibratory feeder 302 is existing equipment. One end of the feeding track 301 is located below the discharge port of the vibratory feeder 302 without contact, so as to prevent the vibration amplitude of the vibratory feeder 302 from being too large during vibration screening and affecting the accuracy of the capping supplied by the feeding track 301. The feeding track 301 includes an inclined section and a vertical section, which are connected, and the inclined section is higher than the other end near the vibratory feeder. The bottom of the vertical section of the feeding track 301 has a discharge port, which corresponds to the capping section of the limiting groove 2. The cap-separating mechanism 303 is fixedly installed on the discharge port. During use, the vibratory feeder... A cap is placed inside 302. The vibrating plate 302 vibrates and screens the caps, causing them to enter the feeding track 301 in a queue. The caps move along the feeding track 301 and fall to the cap-separating mechanism 303. The cap-separating mechanism 303 opens and closes according to the signal from the control terminal. When the cap-separating mechanism 303 opens, a cap falls into the cap section of the limiting groove 2 in a predetermined posture. Then the cap-separating mechanism 303 closes. The cap being output from the outlet in a predetermined posture means that after the cap is output from the vibrating plate 302, it is output through the feeding track 301 with the opening end of the cap facing the opening end of the packaging tube. The feeding track 301 is trough-shaped or other structures that can limit the caps, such as the frame-shaped feeding track of this utility model, to prevent the caps from changing posture during the conveying process.

[0022] like Figure 2 As shown: The cap-separating mechanism includes a cap-separating cylinder 304, cap-separating grippers 305, and cap-separating baffles 306. The cap-separating cylinder 304 is a telescopic cylinder and is connected to the control terminal signal. It is fixedly installed on one side of the discharge port end of the feeding track 301 with the cylinder axis pointing downwards. Two cap-separating grippers 305 are rotatably installed on the same side via a rotating shaft. The two cap-separating grippers 305 have a Z-shaped structure and are arranged mirror images of each other. The upper end of the cap-separating gripper 305 is rotatably connected to the lower part of the cap-separating cylinder 304. The two cap-separating grippers 305 have a certain rotational clearance near their respective ends. This rotational clearance corresponds vertically to the cylinder axis of the cap-separating cylinder 304, and its rotational clearance is less than the diameter of the cylinder axis. The bottom of each of the two cover grabbers 305 is fixedly equipped with a cover baffle 306 that controls the opening and closing of the feeding track 301. During use, the working speed of the cover-separating cylinder 304 is matched to the conveying speed of the roller conveyor 1. When the cylinder shaft of the cover-separating cylinder 304 extends, it presses the two cover grabbers 305 downwards, causing them to rotate around the pivot point. The bottom of the cover grabbers 305 drives the two cover baffles 306 away from each other, opening the feeding port of the feeding track 301. The cover plug falls from the outlet into the cover plug section of the limiting groove 2 in a predetermined posture. When the cylinder shaft retracts, the two cover grabbers 305 approach each other due to gravity, thus closing the outlet (e.g., ...). Figure 4 ).

[0023] The cap-splitting mechanism 303 can also employ a design where semi-circular geared discs are respectively arranged opposite each other at the near ends of the two cap-splitting grippers 305. A rack is connected to the cylinder shaft of the cap-splitting cylinder 304, with the rack positioned between the teeth of the two cap-splitting grippers 305. The rack meshes with the geared discs of the two cap-splitting grippers 305, and the extension and retraction of the cylinder shaft drives the cap-splitting baffle 306 to open and close left and right, thereby controlling the opening and closing of the discharge port of the feeding track 301 (e.g., ...). Figure 3 ).

[0024] Specific usage method: Before the capping feeding mechanism 3 outputs the caps, the vibrating plate 302 vibrates and screens the caps to output them in a predetermined posture to the feeding track 301. The caps slide along the feeding track 301 in a predetermined posture to the upper part of the cap-separating baffle 306 of the cap-separating mechanism. At this time, the cap-separating baffle 306 is in a closed state to the feeding track 301. Multiple caps are arranged in a queue in the feeding track 301. After the single cigar packaging equipment at the front end conveys the packaging tube containing the cigar to the limiting groove, the roller conveyor 1 drives the limiting groove 2 containing the packaging tube to move to the lower part of the discharge port of the feeding track 301, so that the cap section corresponds to the discharge port of the feeding track 301. The control terminal controls the cap-separating cylinder. In operation 304, the cylinder shaft of the cap-separating cylinder 304 drives the two cap-separating grippers 305 to rotate around the pivot point to both sides. The bottom of the cap-separating grippers 305 drives the two cap-separating baffles 306 to move away from each other. The discharge port of the feeding track 301 opens, and the cap plug falls from the discharge port into the cap plug section of the limiting groove 2 in a predetermined posture. At the same time as the cap plug leaves the feeding track 301, the cylinder shaft of the cap-separating cylinder 304 retracts, and the bottom of the cap-separating grippers 305 drives the two cap-separating baffles 306 to move closer together to close the discharge port. The roller conveyor 1 drives the packaging tube cap plug to move to the rear clamping process. The cap plug is assembled to the open end of the packaging tube in the clamping process. Repeating the above process can complete the cap plug to be fed out at a uniform speed in the correct posture.

More specifically, various variations and improvements can be made to the components and / or layout of the subject matter combination within the scope of the present application. Besides variations and improvements to the components and / or layout, other uses will be apparent to those skilled in the art.
