Detailed implementation manners

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0025] This application provides an automatic packaging device for packaging boxes that is convenient for adjusting the packaging size, mainly used to solve the problem that existing devices in the prior art may require replacing different molds and adjusting mechanisms, which not only increases the operation complexity but also greatly improves the equipment cost, and provides the following technical solutions. The following will be combined with Figures 1-4 make a detailed description:

[0026] An automatic packaging device for packaging boxes that is convenient for adjusting the packaging size, comprising:

[0027] A roller conveyor 1 for conveying packaging boxes, with supports 2 fixedly arranged at intervals on one side of the roller conveyor 1;

[0028] A material guiding hopper 3 fixedly arranged on the support 2, the material guiding hopper 3 includes a vertically arranged discharge hopper 301, and the upper end of the discharge hopper 301 is communicated with a feed hopper 302. The feed hopper 302 is inclined upward and has an open structure at its top;

[0029] An intermittent feeding mechanism 4 arranged in the middle of the feed hopper 302 for intermittently feeding columnar materials from the feed hopper 302 into the discharge hopper 301;

[0030] A limiting mechanism 5 arranged in the middle of the roller conveyor 1 for limiting the packaging boxes and columnar materials so that they are located in the middle of the roller conveyor 1, and the limiting mechanism 5 can be adjusted to adapt to packaging boxes of different sizes.

[0031] Description of the specific working process and principle:

[0032] In the first step, start the equipment, the roller conveyor 1 starts to work, and conveys the empty packaging boxes to below the discharge hopper 301;

[0033] In the second step, the columnar material is put in through the feed hopper 302. The inclined feed hopper 302 is designed to enable the material to slide in smoothly.

[0034] In the third step, the intermittent feeding mechanism 4 works, and the pushing plate 401 intermittently pushes the columnar material from the feed hopper 302 into the discharge hopper 301.

[0035] In the fourth step, the discharge hopper 301 accurately feeds the material into the packaging box below.

[0036] In the fifth step, the limiting mechanism 5 can be adjusted to adapt to packaging boxes and materials of different sizes, ensuring the stable positions of the material and the packaging box during the conveying process.

[0037] In the sixth step, the packaging box filled with the material continues to be conveyed by the roller conveyor 1 to the next process (for sealing) or the collection area.

[0038] In the seventh step, if it is necessary to replace the material or adjust the size of the packaging box, the quick switching can be achieved by adjusting the limiting mechanism 5.

[0039] This automatic packaging equipment for packaging boxes with adjustable packaging size greatly improves the flexibility of the packaging equipment through the combined design of the roller conveyor 1, the limiting mechanism 5, the guiding hopper 3 and the intermittent feeding mechanism 4. By adjusting the limiting mechanism 5, it can adapt to packaging boxes of different sizes, avoiding frequent die replacement and mechanism adjustment, and reducing the equipment cost and maintenance cost.

[0040] It should be noted that this device only provides the loading part during the packaging process. For the opening and sealing of the packaging box, the existing technology can be used to complete them.

[0041] Such as Figure 4As shown, in some embodiments, the limiting mechanism 5 includes limiting blocks 501 symmetrically arranged in the middle of the roller conveyor 1. A guiding block 502 is fixedly provided in the middle of the top of the limiting block 501. The guiding block 502 is triangular. Rectangular notches adapted to the guiding block 502 are formed on both sides of the discharge hopper 301. A driving member is arranged in the middle of the roller conveyor 1. The driving member is used to drive the two limiting blocks 501 to move towards each other or away from each other. More specifically, the limiting mechanism 5 is mainly responsible for ensuring the accurate position of the packaging box and the columnar material on the roller conveyor 1, so that the columnar material can be accurately loaded into the packaging box. Its adjustable characteristic enables the equipment to quickly adapt to different sizes of packaging requirements, greatly improving the packaging efficiency and accuracy, while reducing the operation complexity and production cost. The function of the limiting block 501 is to physically limit the position of the packaging box to ensure that they do not deviate from the roller conveyor 1 during the conveying process. The guiding block 502 cooperates with the rectangular notches on both sides of the discharge hopper 301, so that when the material is released from the discharge hopper 301, it can smoothly enter the interior of the packaging box along the guiding block 502 without tilting or damage to the material caused by position deviation (in order to avoid material damage, a guide groove can be designed on the inclined surface of the guiding block 502, and this guide groove is adapted to the end of the columnar material). The driving member is used to control the movement of the two limiting blocks 501 towards each other or away from each other, so that the limiting mechanism 5 can adapt to packaging boxes of different widths.

[0042] As Figure 4 shown, in some embodiments, the driving member includes a mounting rod 503 rotatably connected between the inner side walls of the roller conveyor 1. A motor 504 is installed on the outer wall of the roller conveyor 1. The output shaft of the motor 504 is connected to one end of the mounting rod 503. Threads with opposite spiral directions are formed on both sides of the mounting rod 503, and movable blocks 505 are symmetrically threadedly connected. The limiting blocks 501 are fixedly provided on the tops of the movable blocks 505. More specifically, when the motor 504 is started, the rotational power of the output shaft is transmitted to the mounting rod 503. Threads with opposite spiral directions are formed on both sides of the mounting rod 503. This design enables the two movable blocks 505 on both sides to move correspondingly according to the rotation direction of the threads when the mounting rod 503 rotates. One movable block 505 moves inward when the mounting rod 503 rotates, and the other movable block 505 moves outward, or vice versa, depending on the rotation direction of the threads. The movable blocks 505 are fixedly arranged with the limiting blocks 501. The movement of the movable blocks 505 will directly drive the movement of the limiting blocks 501. Therefore, when the motor 504 drives the mounting rod 503 to rotate, the movement of the movable blocks 505 will correspondingly adjust the position of the limiting blocks 501. By controlling the rotation direction of the motor 504, the movement of the limiting blocks 501 towards each other or away from each other can be accurately controlled. Moving towards each other means that the two limiting blocks 501 move towards each other, usually used to adapt to narrower packaging boxes; moving away from each other means that the limiting blocks 501 move away from each other, suitable for wider packaging boxes.

[0043] As Figure 4 shown, in some embodiments, on one side of the two limiting blocks 501 facing each other, mounting grooves are formed, and inside the mounting grooves, contact wheels 506 are rotatably connected at equal intervals through a rotating shaft. More specifically, the contact wheels 506 are rotating components installed inside the mounting grooves. They contact the side surface of the packaging box, playing a role in stabilizing and guiding. In addition, the rotation of the contact wheels 506 can reduce the friction of the packaging box during transportation, ensuring its smooth movement.

[0044] As Figure 4 shown, in some embodiments, arc-shaped notches 5011 are formed at equal intervals at the bottom of the limiting blocks 501. The arc-shaped notches 5011 are slidably connected to the rollers of the roller conveyor 1. More specifically, the design of the arc-shaped notches 5011 enables the limiting blocks 501 to closely fit on the rollers of the roller conveyor 1. When the rollers rotate, the contact between the arc-shaped notches 5011 and the rollers ensures the stability of the limiting blocks 501, preventing them from shifting or swinging during movement, thereby ensuring that the packaging box and the materials maintain a stable position during transportation.

[0045] As Figure 3 shown, in some embodiments, the intermittent feeding mechanism 4 includes a pushing plate 401 hinged to the bottom of the feeding hopper 302. The pushing plate 401 is hook-shaped. A rectangular channel 3021 is formed at the bottom side of the middle part of the feeding hopper 302. An arc-shaped block 402 is fixedly installed inside the feeding hopper 302 near the rectangular channel 3021. The hook end of the pushing plate 401 slidably penetrates through the rectangular channel 3021 and is slidably connected to the arc-shaped block 402. Symmetrically fixed to the bottom of the hinged end of the pushing plate 401 are extension plates 403. A strip-shaped hole 4031 is formed in the middle of the extension plates 403. A sliding rod 404 is slidably inserted into the strip-shaped hole 4031. A hydraulic cylinder 405 is hinged to the middle of the bracket 2. The piston end of the hydraulic cylinder 405 is hinged to the middle of the sliding rod 404. More specifically, the intermittent feeding mechanism 4 is responsible for precisely pushing the columnar materials from the feeding hopper 302 to the discharging hopper 301 in the automatic packaging equipment. Among them, the pushing plate 401 is hinged to the bottom of the feeding hopper 302, and its main function is to push the columnar materials piled up in the feeding hopper 302 towards the feeding hopper 301 of the discharging hopper 301. The rectangular channel 3021 is for accommodating the hook end of the pushing plate 401 and allowing it to slide through. The size and position of the rectangular channel 3021 need to match the pushing plate 401 to ensure smooth material transportation. The function of the arc-shaped block 402 is to guide the pushing plate 401 to move smoothly along a predetermined path, reducing the wear that may be caused by direct friction. At the same time, it can serve as a bridge for the columnar materials to pass through. By the telescopic movement of the piston of the hydraulic cylinder 405 to drive the sliding rod 404, and then push the pushing plate 401 to perform intermittent feeding actions.

[0046] As Figure 3As shown, in some embodiments, the hook end of the pusher plate 401 is configured with an arc-shaped groove. More specifically, in the absence of the arc-shaped groove, the material may fall back into the feed hopper 302 due to vibration or rolling during the pushing process. The main function of the arc-shaped groove is to prevent the columnar material from rolling back into the feed hopper 302 during the pushing process. When the pusher plate 401 moves forward to push the material towards the discharge hopper 301, the arc-shaped groove can effectively accommodate the material and prevent it from rolling or slipping during the movement.

[0047] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
