Description
Technical Field
[0001] This utility model belongs to the technical field of wine box packaging lid card transfer equipment, and relates to a guide mechanism for feeding out wine box packaging lid card. Background Technology
[0002] In the process of preparing the cardboard lid for wine box packaging, the cardboard lid needs to be coated with glue and bonded to the cardboard shell to form the lid. In the preparation process, the lid first needs to be loaded from the storage rack and conveyed to the gluing machine via a conveyor belt. However, when gluing, using a conventional conveyor belt directly will cause the lightweight lid to shift, which will affect the gluing quality and make the gluing quality unstable. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a guide mechanism for feeding paperboard to the lid of a wine box, which can achieve directional movement and ensure stable and reliable glue application quality.
[0004] The technical solution adopted by this utility model is as follows: a guide mechanism for feeding paperboard for wine box packaging lids, including two guide limiting strips and pressing blocks. The two guide limiting strips are respectively arranged on both sides of the conveyor belt and keep in close contact with the conveyor belt. The two guide limiting strips are fixedly connected to two sliding plates. The two sliding plates are connected to two guide rods through linear bearings. The two guide rods are fixedly connected to both sides of the belt frame of the conveyor belt through fixed seats. Multiple pressing blocks are used and arranged along the length of the conveyor belt. The upper end is fixedly connected to the longitudinal beam. The longitudinal beam is fixedly connected to the middle of the two guide rods through two supports and the pressing blocks maintain a gap with the belt of the conveyor belt. The two sliding plates are driven to move relative to each other by a screw and nut drive mechanism. The screw and nut drive mechanism is installed on two fixed seats.
[0005] Furthermore, the aforementioned lead screw and nut drive mechanism includes a lead screw and two nuts with opposite directions of rotation. The two nuts are helically connected to the lead screw, and the two ends of the lead screw are rotatably connected to two fixed seats through bearings, with one end extending out of the bearing and connected to a rotating disk.
[0006] Furthermore, each of the two guide rods is equipped with two limiting discs. The four limiting discs limit the longitudinal beam. The support is equipped with a sleeve hole. After the guide rod is fitted into the sleeve hole, it is locked with a locking screw. The top of the support is fixedly connected to the bottom of the longitudinal beam. The locking screw passes through the longitudinal beam from the top surface downwards and is screwed onto the support. Its inner end can abut against the guide rod for locking.
[0007] Furthermore, the bottom of the aforementioned pressing block is equipped with a double row of rollers.
[0008] Furthermore, guide pressing rollers are arranged above the input ends of the two guide limit strips. The four corners of the top plate of the guide pressing roller frame are connected to the cantilever beam by four suspension ropes. The cantilever beam is connected to the feeding machine frame by a portal frame. The guide pressing roller is located above the feed end of the conveyor belt, and the lowest point of the guide pressing roller surface is 1-1.5mm away from the top surface of the conveyor belt.
[0009] Furthermore, a flexible paper baffle that bends toward the conveyor belt is provided on the upper end of the column limiting rod of the feeding frame below the aforementioned guide pressing roller.
[0010] Furthermore, a curved flexible guide card is attached to the output side of the aforementioned guide pressing roller, and the flexible guide card is connected to the pressing block set on the conveyor belt.
[0011] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model arranges two guide limiting strips on the conveyor belt and a pressing block on the top, which can press the strip structure (formed by joining two packaging box cover cards together) onto the conveyor belt and place it between the two guide strips for directional and stable conveying. This facilitates stable entry into the designated position of the gluing machine for gluing, improving the gluing quality and stability. The guide limiting strips are driven by a guide rod, linear bearing, sliding plate, and screw nut drive mechanism, thereby achieving precise adjustment of the relative position of the two guide limiting strips. This makes it convenient to adjust the position of packaging box cover cards of different widths, and has a wider range of applications. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0016] Example 1: Refer to Figure 1-3As shown, a guide mechanism for feeding paperboard for wine box packaging lids includes two guide limiting strips 1 and pressing blocks 2. The two guide limiting strips 1 are respectively arranged on both sides of the conveyor belt 3 and keep in contact with the conveyor belt 3. The two guide limiting strips 1 are fixedly connected to two sliding plates 4. The two sliding plates 4 are connected to two guide rods 6 through linear bearings 5. The two ends of the two guide rods 6 are fixedly connected to both sides of the belt frame of the conveyor belt 3 through fixed seats 7. Multiple pressing blocks 2 are arranged along the length of the conveyor belt 3. The upper end is fixedly connected to a longitudinal beam 8. The longitudinal beam 8 is fixedly connected to the middle of the two guide rods 6 through two supports 10, and the pressing blocks 2 maintain a gap with the belt of the conveyor belt. The two sliding plates 4 are driven to move relative to each other by a screw and nut drive mechanism 11. The screw and nut drive mechanism 11 is installed on two fixed seats 7.
[0017] To simplify the structure, the lead screw and nut drive mechanism 11 includes a lead screw 1101 and two nuts 1102 with opposite directions of rotation. The two nuts 1102 are spirally connected to the lead screw 1101. The two ends of the lead screw 1101 are rotatably connected to two fixed seats 7 via bearings 9, and one end extends out of the bearing and connects to the rotating disk 1103. By arranging two nuts with opposite directions of rotation on a single lead screw, rotating the lead screw can drive the two nuts to move relative to each other, thereby quickly adjusting the spacing. The lead screw is made of two sections, with a connector fixed in the middle, which facilitates the manufacturing of controls with opposite directions of rotation.
[0018] To quickly position the longitudinal beam, two limit discs 12 are provided on each of the two guide rods 6. The four limit discs 12 limit the longitudinal beam. The support 10 is provided with a sleeve hole. After the sleeve hole is fitted with the guide rod 6, it is locked with a locking screw 13. The top of the support 10 is fixedly connected to the bottom of the longitudinal beam. The locking screw 13 passes through the longitudinal beam from the top surface downward and is screwed onto the support 10. Its inner end can abut against the guide rod 6 for locking. The two limit discs can quickly limit the longitudinal beam into the groove and are fixed with the support using a set screw. The connection is convenient and quick.
[0019] To improve pressing reliability, the bottom of the pressing block 2 is equipped with double-row rollers 201. The double-row rollers have a large pressing contact surface, which presses the wine box lid card into contact with the conveyor belt, thus improving the conveying reliability.
[0020] When a paper jam occurs at the feed end of the conveyor belt, the paper jam is suspended by an adsorption mechanism before being conveyed to the conveyor belt. However, the side of the paper jam suspended near the conveyor belt cannot quickly adhere to the conveyor belt for conveying, thus affecting the stability of the feed. Guide pressing rollers 14 are arranged above the input ends of the two guide limit bars 1. The four corners of the top plate of the guide pressing roller 14's frame are connected to the cantilever beam 16 via four suspension ropes 15. The cantilever beam 16 is connected to the feeding frame 20 via a portal frame 19. The guide pressing roller 14 is located above the feed end of the conveyor belt 3, and the lowest point of the guide pressing roller 14's wheel surface is 1-1.5mm from the top surface of the conveyor belt 3. By setting up guide pressing rollers with a guiding function, the suspended end can be... The box cover card is quickly introduced into the limiting slot on the conveyor belt, and the rollers press it firmly onto the conveyor belt for transport. This facilitates smooth transport after the suction cup is released and improves the stability of the box cover card entering the conveyor belt. It also prevents the end of the box cover card from hitting the limiting structure on the conveyor belt and causing damage. Flexible paper pieces 22 are also provided on both sides of the entry end of the limiting slot. The flexible paper pieces 22 are fixedly connected to the guide limiting strip and cantilevered out a section before bending downwards. This helps to prevent wear during the lowering of the front end of the card. The guide pressing roller connected by the flexible rope can play a buffering role and prevent the box cover card from being damaged by excessive force due to rigid connection. Under the gravity of the guide pressing roller, the box cover card is kept pressed firmly against the conveyor belt.
[0021] To safely deliver the packaging box lid card and prevent it from rubbing against the limiting rod, a flexible paper baffle 17 that bends towards the conveyor belt is installed on the upper end of the limiting rod 21 of the column of the feeding frame 20 below the guide pressing roller 14. The flexible paper baffle can provide auxiliary support and transition when the end of the box lid card (the end before entering and the end after the suction cup puts down the card) is suspended and bent downwards, preventing the decorative glossy surface of the box lid card from rubbing against the top of the limiting rod and causing damage or scratches, thus improving the safety of conveying. In addition, it can play a better role in directional movement in conjunction with the guide pressing roller. A bent flexible guide card 18 is attached to the output side of the guide pressing roller 14. The flexible guide card 18 is connected to the pressing block 2 set on the conveyor belt 3. This structure can guide the upwardly bent card into the pressing block 2, preventing the card from bending and hitting the pressing block when passing through the guide pressing roller 14.

Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
