Description

Technical Field

[0001] The utility model belongs to the technical field of rubber tube production, and in particular relates to a coding device for tubular rubber products. Background Art

[0002] When the applicant produces rubber foam tubes, the finished products are made after extrusion, foaming and drying. The finished rubber foam tubes need to be sprayed with production information before packaging. At present, ordinary printing wheels are mostly used to print on rubber products, but for tubular rubber products, the printing wheels are inconvenient to use.

[0003] Therefore, some existing technologies for using inkjet printers to spray codes on tubular rubber products have emerged, such as patent document CN218367085U, which proposes an automatic inkjet printer for rubber tubes. However, the inkjet printer is only suitable for the inkjet operation of a single rubber tube. The applicant uses a six-port extruder during production, which can produce six rubber tubes at most at the same time. If the method of spraying codes on a single rubber tube is adopted, the production efficiency will be greatly affected. Utility Model Content

However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0043] Example 1: See Figure 1-Figure 4 The purpose of this embodiment is to provide a coding device for tubular rubber products. The coding device 2 is arranged on the upper part of the roller conveyor belt 1, and is used to code multiple tubular rubber products transmitted by the roller conveyor belt 1.

[0044] The coding device 2 comprises a door frame 21 fixed on the upper part of the roller conveyor belt 1, a lifting mechanism, a sliding mechanism, a coding mechanism and a limiting mechanism.

[0045] The portal frame 21 includes a vertical column 211 and a horizontal beam 212. The two columns 211 are fixedly arranged on the frames on both sides of the roller conveyor 1, respectively. The beam 212 is arranged on the top of the column 211, and the two ends of the beam 212 are fixedly connected to the top of the column 211 one by one. The columns 211 and the beam 212 are both groove structures, the grooves of the two columns 211 are opposite, the groove of the beam 212 is downward, and the groove of the beam 212 is covered at the end of the column 211.

[0046] The lifting mechanism is arranged in the door frame 21, and includes a lifting beam 221, a screw 222, a screw seat 223 and a hand wheel 224. The lifting beam 221 is arranged horizontally just below the cross beam 212; both ends of the lifting beam 221 are located in the column 211, and screw seats 223 are fixedly arranged at both ends of the lifting beam 221, and the axis of the screw seat 223 is vertical; two screws 222 that match the screw seat 223 one-to-one are arranged vertically in the column 211 one-to-one; the bottom ends of the screws 222 are rotatably connected to the frame of the roller conveyor 1, or are rotatably connected to the bottom end of the column 211; the top end of the screw 222 is rotatably connected to the cross beam 212, and a hand wheel 224 is fixedly arranged on the top end of the screw 222 after passing through the cross beam 212. By rotating the hand wheel 224, the screw 222 is driven to rotate, so that the lifting beam 221 is raised or lowered.

[0047] The sliding mechanism is arranged on the lifting beam 221, and comprises a motor 231, a pulley 232, a belt 233, a slide rail 234 and a slider 235. The lifting beam 221 is a groove-shaped structure, and the groove faces the conveying direction of the roller conveyor belt 1. The motor 231 is arranged at the upper part of one end of the lifting beam 221, and the transmission shaft of the motor 231 extends vertically downward into the lifting beam 221; both ends of the lifting beam 221 are provided with rotatably connected pulleys 232 near the screw seat 223, and the central axes of the pulleys 232 are vertical, one of the pulleys 232 is rotatably connected to the lifting beam 221, and the other pulley 232 is fixedly connected to the output shaft of the motor 231; a belt 233 is tensioned between the two pulleys 232; a slide rail 234 is arranged inside the belt 233, and the slide rail 234 is arranged along the length direction of the lifting beam 221, and the slide rail 234 is fixedly connected to the lifting beam 221; the slider 235 is sleeved on the slide rail 234, and is slidably connected to the slide rail 234 and the lifting beam 221, and the slider 235 is also fixedly connected to the belt 233. When the motor 231 rotates, the driving pulley 232 rotates, and the pulley 232 drives the belt 233 to move, so that the slider 235 slides along the lifting beam 221.

[0048] The coding mechanism is arranged on the slider 235, and includes a coding terminal bracket 241 and a coding terminal 242. The coding terminal bracket 241 is fixedly connected to the slider 235, and the coding terminal 242 is installed on the coding terminal bracket 241, and the coding direction of the coding terminal 242 is vertically downward. The height of the nozzle at the bottom of the coding terminal 242 is higher than the bottom height of the lifting beam 221, and the height difference between the nozzle at the bottom of the coding terminal 242 and the bottom of the lifting beam 221 is the optimal coding distance of the coding terminal 242. The lifting mechanism can adjust the up and down height of the coding terminal 242, and the sliding mechanism can adjust the left and right horizontal position of the coding terminal 242.

[0049] The limiting mechanism is arranged directly below the lifting beam 221, and includes a support beam 251 and a limiting cylinder 252. The support beam 251 is parallel to the lifting beam 221; the support beam 251 is located between the two rollers of the roller conveyor belt 1, and the two ends are respectively fixedly connected to the frames on both sides of the roller conveyor belt 1, and the top surface of the support beam 251 is flush with the top height of the roller.

[0050] This embodiment is also provided with a control mechanism, and the spray terminal 242 and the motor 231 are both electrically connected to the control mechanism.

[0051] When this embodiment is working, the hand wheel 224 is used to make the lifting beam 221 drop down and land on the limiting cylinder 252. At this time, the limiting cylinder 252, the lifting beam 221 and the supporting beam 251 will limit the tubular rubber product. The downstream side of the supporting beam 251 is the coding position of the spray terminal 242. Then, the control mechanism sets the coding content, the number of tubular rubber products to be coded and the position where each tubular rubber product passes through the limiting cylinder 252. When coding is required, the control mechanism controls the rotation of the motor 231 to move the spray terminal 242 to a coding position for coding; after the current coding is completed, the spray terminal 242 returns to the initial position, waits for a certain period of time, and then codes are sprayed again in sequence.

[0052] At the same time, in order to facilitate the tubular rubber product to pass through the lifting beam 221 and the support beam 251, as shown in FIG. Figure 4 As shown, the edges of the lifting beam 221 and the supporting beam 251 on the upstream side (the direction in which the tubular rubber product is transmitted) are rounded.

[0053] In this embodiment, the crossbeam 212 adopts a groove structure with the groove facing downward, so cables, pipelines, etc. can be arranged inside the crossbeam 212, making the site tidier.

[0054] By replacing the limiting cylinders 252 of different specifications, the utility model can be suitable for tubular rubber products with different diameters.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
