Description

Technical Field

[0001] This utility model relates to an automatic marking device for an automatic cigarette box bundling machine. Background Technology

[0002] Before being made into cigarette boxes, cigarette outer packaging boxes are processed in a printing factory as pre-printed and cut pieces of cardboard. A certain number of these cardboard boxes are stacked together and then bundled with coated paper tape using an automatic cigarette box bundling machine (see Chinese Invention Patent Application Publication No. CN120081041A) to facilitate subsequent packaging, handling, and transportation. After these stacks of cardboard boxes are transferred to the cigarette manufacturing plant, the cigarette production equipment automatically processes them into cigarette boxes and packages the cigarettes into cigarette packs.

[0003] This is to enable the traceability of cigarette cardboard products to every crew member in the printing plant. Before the stack of cigarette cardboard enters the automatic cigarette pack bundling machine, a line of a different color needs to be drawn on the front side of the stack with a marker. The color and position of the line drawn by each crew member correspond one-to-one. The lines drawn on the front side of the stack of cigarette cardboard are invisible after the cigarette production equipment automatically makes them into cigarette packs.

[0004] Currently, in printing plants, workers manually mark the stacks of cigarette boxes. This manual marking is inefficient, out of sync with automatic cigarette box bundling machines, and produces uneven and crooked lines. As automation levels continue to increase, manual marking can no longer meet the basic requirements of automated and high-efficiency production. Utility Model Content

[0029] The upper and lower cylinders 1 are sliding cylinders and are mounted on the working platform 10 of the automatic cigarette box bundling machine 10A via cylinder seat 11 and profile bracket 12, and are located on the front right side of the working hole 1A.

[0030] The longitudinal cylinder 2 is mounted on the left end face of the slider 13 of the upper and lower cylinders 1 with the piston rod facing backward and via the connecting block 20.

[0031] The pen holder 3 has an L-shaped plane, and the horizontal part of the pen holder 3 is connected to the end of the piston rod of the vertical cylinder 2; a light hole 30 is opened on the upper front part of the vertical part of the pen holder 3.

[0032] The pen holder 4 is located on the left side of the longitudinal part of the pen holder base 3. The pen holder 4 is a rectangular block with its right rear end face protruding beyond its left rear end face. A left pen mounting hole 41 and a right pen mounting hole 42 are correspondingly formed on the right and left rear end faces of the pen holder 4, leading to the front face of the pen holder 4. The front part of the left pen mounting hole 41 and the front part of the right pen mounting hole 42 are both circular insertion holes, while the rear part of both the left pen mounting hole 41 and the right pen mounting hole 42 are both top-opening holes. That is, each of the left pen mounting hole 41 and the right pen mounting hole 42 includes a circular insertion hole and an opening groove 4A extending downwards from the top surface of the pen holder 4 to the top of the insertion hole. The opening groove 4A of the right pen mounting hole 42 is located at a position protruding beyond the left rear end face. A left pen mounting hole 41 is also present on the left side of the pen holder 4. Each of the slot 4A of the mounting hole 41 and the slot 4A of the right pen mounting hole 42 has a bolt fastening hole. The bolt fastening hole on the left side of the slot 4A is a smooth hole, and the bolt fastening hole on the right side of the slot 4A is a threaded hole. A threaded blind hole 40 perpendicular to the left pen mounting hole 41 and the right pen mounting hole 42 is opened on the front right side of the pen holder 4. A shoulder screw 5 passes through the smooth hole 30 of the pen holder base 3 to the left and is screwed into the threaded blind hole 40 of the pen holder 4. Since the shoulder of the shoulder screw 5 is in sliding fit with the smooth hole 30 of the pen holder base 3, when the shoulder screw 5 is tightened with the pen holder 4, there is a gap between the right side of the pen holder 4 and the left side of the longitudinal part of the pen holder base 3, so that the pen holder 4 can rotate around the smooth hole 30 of the pen holder base 3.

[0033] The drawing pen 6 is installed in the left pen mounting hole 41 or the right pen mounting hole 42 of the pen holder 4; after the drawing pen 6 is inserted into the insertion hole of the left pen mounting hole 41 or the insertion hole of the right pen mounting hole 42, the insertion hole is contracted by the fastening screw 4B to clamp the drawing pen 6.

[0034] The pen holder adjustment mechanism includes a limiting seat 71 and a limiting screw 72; wherein, the limiting seat 71 is L-shaped, and the straight part of the limiting seat 71 is installed on the upper rear left end face of the longitudinal part of the pen holder base 3, so that the horizontal part of the limiting seat 71 and the working platform 10 form an angle of 15 to 20°; the limiting screw 72 is vertically installed at the center of the horizontal part of the limiting seat 71 and its end abuts against the top surface of the pen holder 4.

[0035] The pen holder adjustment mechanism includes a spring seat 81, a spring 82, and an adjusting screw 83. The spring seat 81 is cylindrical with a threaded hole at the bottom. The spring seat 81 is installed parallel to the limiting screw 72 in the pen holder limiting mechanism on the lower rear left end face of the longitudinal part of the pen holder base 3. The spring 82 is installed in the inner hole of the spring seat 81. The adjusting screw 83 is screwed from the bottom of the spring seat 81 into the threaded hole at the bottom of the spring seat 81, so that the top of the spring 82 abuts against the rear bottom surface of the pen holder 4.

[0036] The pen holder 4 has two pen mounting holes for use by multiple work groups. Each work group member can choose to use the left pen mounting hole 41 or the right pen mounting hole 42 and use a different colored drawing pen 6.

[0037] The pen holder limiting mechanism and the pen holder adjusting mechanism ensure that the angle between the left pen mounting hole 41 or the right pen mounting hole 42 on the pen holder 4 and the working platform 10 is 15-20°.

[0038] When the automatic marking device 20A of this invention is not in operation, the slider 13 of the upper and lower cylinders 11 is in the low position, that is, the tip of the marking pen 6 is located in the working hole 1A of the working platform 10. When the worker places a stack of cigarette cardboard 100 on the working platform 10 of the automatic cigarette box bundling machine 10A and it is located in the position of the cardboard output unit 101, the control system of the automatic cigarette box bundling machine 10A issues a command to extend the piston rod of the paper pressing cylinder 101A in the cardboard output unit 101 to press down the stack of cigarette cardboard 100. Then, the control system of the automatic cigarette box bundling machine 10A issues a command to extend the piston rod of the longitudinal cylinder 2 in the automatic marking device 20A of this invention, so that the tip of the marking pen 6 contacts the front side of the stack of cigarette cardboard 100. Then, the upper and lower cylinders 11 move from bottom to top to the set position, that is, drive the marking pen 6 from bottom to top from position I to position II to automatically draw a line on the front side of the stack of cigarette cardboard 100 (see Figure 2 Due to the action of the spring 82 in the pen holder adjustment mechanism, the marking pen 6 is always in contact with the front side of the cigarette box cardboard stack 100. Then the piston rod of the longitudinal cylinder 2 retracts, and the upper and lower cylinders 1 retract to the starting position, and the automatic marking is repeated in a cycle. After the automatic marking device 20A of this utility model completes the marking, the automatic cigarette box bundling machine 10A performs the subsequent actions until the cigarette box cardboard stack 100 is finished bundling.

[0039] In the non-operating state, the automatic marking device 20A of this invention has spring 82 in the pen holder adjustment mechanism pressing against the rear bottom surface of the pen holder 4, causing the rear of the pen holder 4 to swing upward until the top surface of the rear of the pen holder 4 touches the end of the limiting screw 72 of the pen holder limiting mechanism. When the tip of the marking pen 6 is against the front side of the cigarette box cardboard stack 100 for marking, the top surface of the rear of the pen holder 4 may not contact the end of the limiting screw 72. When the automatic marking device 20A of this invention starts working, due to the action of spring 82, the tip of the marking pen 6 always softly adheres to the front side of the cigarette box cardboard stack 100 to draw a straight line, as smooth as hand marking, but more uniform and straight than hand marking. The adjusting screw 83 can adjust the pressure of the marking pen 6 when marking, and is locked by the nut after adjustment.

[0040] The above embodiments are for illustrative purposes only and are not intended to limit the present invention. Those skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and should be defined by the claims.
