Description

Technical Field

[0001] The utility model relates to the technical field of conveying mechanisms, in particular to a conveying mechanism of an automatic top-bottom cover paper box forming machine. Background Technique

[0002] The automatic top-bottom cover paper box forming machine uses devices such as suction cups and cylinders, and lifts and sucks the color boxes electrically, conveys them to the next working station, and performs the pushing, forming and folding of the paper boxes. During the pre-forming process, the machine will first fold the bottom surface of the paper box, and then fold the left and right side flaps to make the paper box firmly snap-connected. Finally, the finished paper box will be conveyed to the production line to complete the entire production process. The existing conveying mechanisms of automatic top-bottom cover paper box forming machines can basically meet the daily use requirements, but there are still some deficiencies that need to be improved.

[0003] In the actual use process of the widely used conveying mechanisms of automatic top-bottom cover paper box forming machines on the market, the conveying positions of different paper boxes cannot be positioned, resulting in inconsistent conveying positions of the paper boxes, so that the suction cups cannot accurately identify the positions of the paper boxes, and manual transfer of the conveyed paper boxes is required. For this reason, we propose a conveying mechanism of an automatic top-bottom cover paper box forming machine to solve the above problems. Content of the Utility Model

Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0021] The present utility model provides a technical solution: As Figures 1 to 4 shown, in this embodiment, a conveying mechanism of an automatic top-and-bottom cover carton forming machine includes a fixed frame 1, a conveyor belt 2 installed on the fixed frame 1, and a control switch 3. Side end plates 4 are arranged on both sides of the conveyor belt 2. Guiding and positioning plates 5 are rotatably connected to the front ends of the two groups of side end plates 4. Threaded sleeves 6 are installed at the front ends of the two groups of conveyor belts 2. Threaded rods 7 are threadedly connected in the two groups of threaded sleeves 6. Turntables 8 are fixed to the opposite ends of the two groups of threaded rods 7. Pull handles 9 are installed on the two groups of turntables 8. Guiding grooves 10 are installed at the opposite ends of the two groups of guiding and positioning plates 5. Rollers 11 are arranged in the two groups of guiding grooves 10. Rotating seats 12 are arranged at the opposite ends of the two groups of rollers 11. The opposite ends of the two groups of threaded rods 7 are rotatably connected to the rotating seats 12. Rotating positioning components are arranged above the two groups of threaded sleeves 6.

[0022] When it is necessary to convey cartons of different sizes, the pull handles 9 on the two groups of turntables 8 can be toggled, so that the two groups of threaded rods 7 rotate along the threaded sleeves 6. Under the action of the thread, the two groups of threaded rods 7 push the two groups of guiding and positioning plates 5 to move towards each other, and the two groups of rollers 11 slide along the guiding grooves 10, ensuring that the two groups of guiding and positioning plates 5 can rotate normally, so that the two groups of guiding and positioning plates 5 can adjust the distance between the two groups of guiding and positioning plates 5 according to the size of the carton, so that the carton enters between the two groups of guiding and positioning plates 5 driven by the conveyor belt 2, and the two groups of guiding and positioning plates 5 guide the carton to the designated position, thus facilitating the suction cup to position and suck the carton, eliminating the need for manual transfer and improving the convenience of the device during use.

[0023] In other embodiments, the rotation positioning assembly includes a sliding sleeve 13, a sliding block 14, a positioning rod 15, a push rod 16, a return spring 17, and a positioning hole 18. Sliding sleeves 13 are fixed above the two sets of threaded sleeves 6. Sliding blocks 14 are arranged inside the two sets of sliding sleeves 13. Positioning rods 15 are fixed to the opposite ends of the two sets of sliding blocks 14. Push rods 16 are fixed to the tops of the two sets of sliding blocks 14. Return springs 17 are arranged inside the two sets of sliding sleeves 13. Multiple groups of positioning holes 18 are formed in the two sets of turntables 8. The opposite ends of the two sets of positioning rods 15 are inserted into the positioning holes 18 on the two sets of turntables 8.

[0024] By installing a positioning rod 15 above the two sets of threaded sleeves 6, when the turntable 8 needs to be rotated, the push rod 16 can be pushed to make the sliding block 14 drive the positioning rod 15 out of the inside of the positioning hole 18 on the turntable 8, and the sliding block 14 squeezes the return spring 17 to make the return spring 17 contract and store energy. When the rotation of the turntable 8 is completed, the thrust on the push rod 16 can be released, and the return spring 17 in the sliding sleeve 13 releases its elastic force to push the sliding block 14 to move along the inside of the sliding sleeve 13, so that the sliding block 14 drives the positioning rod 15 to be inserted into the positioning hole 18 at the corresponding position on the turntable 8, thereby effectively preventing the turntable 8 from accidentally rotating due to external accidental contact during the use of the device, and improving the stability of the device during use.

[0025] In other embodiments, the outer walls of the two sets of guiding and positioning plates 5 are polished.

[0026] Through this design, the friction between the outer wall of the guiding and positioning plate 5 and the paper box can be effectively reduced, facilitating the guiding of the paper box to the designated position.

[0027] In other embodiments, the outer wall of the sliding block 14 fits well with the inner wall of the sliding sleeve 13, and the sliding block 14 is slidably connected to the sliding sleeve 13.

[0028] Through this design, it is ensured that the sliding block 14 can slide smoothly and quickly along the inner wall of the sliding sleeve 13.

[0029] In other embodiments, the two ends of the return spring 17 are respectively connected to the inner wall of the sliding sleeve 13 and the outer wall of the sliding block 14, and the sliding block 14 forms an elastic connection with the inner wall of the sliding sleeve 13 through the return spring 17.

[0030] Through this design, the return spring 17 can continuously apply elastic force to the sliding block 14, enabling the sliding block 14 to drive the positioning rod 15 to be quickly inserted into the positioning hole 18 on the turntable 8.

[0031] In other embodiments, the outer diameter of the positioning rod 15 is the same as the inner diameter of the positioning hole 18.

[0032] Through this design, when the end of the positioning rod 15 is inserted into the positioning hole 18, it can effectively prevent the positioning rod 15 from shaking in the positioning hole 18, improving the stability of the device during use.

[0033] In other embodiments, multiple groups of positioning holes 18 are evenly distributed on the turntable 8 along the axis of the turntable 8;

[0034] Through this design, the positioning rod 15 can be inserted into the positioning holes 18 at different positions, forming rotational limits for the turntable 8 at multiple angles.

[0035] The electrical components appearing in this text are all electrically connected to an external main controller and industrial electricity, and the main controller can be a conventional known device such as a computer for control.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
