Description

Technical Field

[0001] The utility model relates to the field of carton packaging, in particular to a drilling device with a positioning function. Background Technique

[0002] As an indispensable part of modern logistics, the packaging carton undertakes the important responsibilities of containing, protecting products and being beautiful. Holes are usually punched on the carton. The purpose of punching holes is to improve the tensile strength of the carton. The closer the holes are to the top and bottom, the lower the compressive strength. The compressive strength of the symmetric holes is smaller than that of the asymmetric holes. Therefore, punching holes on the carton is beneficial to the use of carton packaging.

[0003] In the prior art, the cardboard is usually placed on the table manually and then squeezed and fixed. When processing cardboard of different sizes, it is necessary to frequently adjust the squeezing position to prevent blocking the punching points, which is more troublesome to use. And in the prior art, when punching holes in the cardboard, it is usually necessary to manually drill holes, resulting in a long manual positioning time and affecting the punching efficiency.

[0004] Therefore, the technical personnel in this field provide a drilling device with a positioning function to solve the problems put forward in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art, and a drilling device with a positioning function is proposed, which can clamp and fix cardboard of different sizes, and can prevent the cardboard from shifting during the drilling process through the extension plate.

[0034] 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. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0035] Referring to Figure 1-7 , an embodiment provided by the present utility model: A drilling device with a positioning function includes a base 1, a top plate 6, and four bevel gears 12. Two clamping plates 7 are slidably arranged on the upper end surface of the base 1 to clamp and fix the cardboard. Extension plates 9 are slidably arranged inside both clamping plates 7 to prevent the cardboard from slipping forward. Limiting mechanisms 20 are arranged at the bottom end surfaces of the inner walls of both clamping plates 7 near one side. Both limiting mechanisms 20 include clamping plates 2002. Arc-shaped grooves 24 are formed at the front ends of the upper end surfaces of both clamping plates 7 on the separated sides. Fixed blocks 2 are fixedly arranged at the upper ends on both sides of the rear end surface of the base 1. First threaded rods 11 are rotatably arranged at the centers of the separated sides of both fixed blocks 2 to facilitate controlling the distance between the two clamping plates 7. A protective shell 13 is fixedly arranged at the upper end near the center of the rear end surface of the base 1;

[0036] Two of the four bevel gears 12 are respectively fixedly arranged at the opposite ends of the two first threaded rods 11, and the other two bevel gears 12 are respectively rotatably arranged at the centers of the front and rear ends of the inner wall of the protective shell 13. An adjustment box 4 is fixedly arranged on the rear end surface of the top plate 6. An adjustment mechanism 21 is arranged inside the adjustment box 4 to control the front and rear positions of the adjustment plate 14. The adjustment mechanism 21 includes two worm wheels 2101 and a worm 2102. Adjustment grooves 23 are formed at the front end surfaces of the inner walls of both sides of the lower end surface of the top plate 6. Third threaded rods 22 are rotatably arranged at the centers of the front end surfaces of the inner walls of both adjustment grooves 23. An adjustment plate 14 is slidably arranged on the lower end surface of the top plate 6. A moving block 19 is slidably arranged inside the adjustment plate 14 to enable the drilling machine 15 to move to both sides. A drilling machine 15 is fixedly arranged at the lower end surface of the moving block 19;

[0037] During use, first move the lever 2001 along the arc-shaped groove 24 to disengage the tip of the clamping plate 2002 from the limiting groove 25. Then, pull out the extension plate 9 outward until the extension plate 9 reaches its maximum extension length. Then, place the cardboard at the center of the upper end face of the base 1 and rotate the first threaded rod 11 to one side. Through the combination of the four meshing bevel gears 12, the other first threaded rod 11 rotates in the opposite direction, thereby driving the two clamping plates 7 to move towards each other. While the clamping plates 7 are moving, the slide rod 10 and the chute 8 cooperate with the slider 26 to prevent the clamping plates 7 from shifting during movement. When the two clamping plates 7 clamp and fix the cardboard, press the extension plate 9 towards the inside of the clamping plate 7 and push the clamping plate 2002 through a plurality of limiting grooves 25. At this time, the clamping plate 2002 will rotate to one side under the action of the rotating shaft 2003, and due to the action of the return spring 2004, when the tip of the clamping plate 2002 and the limiting groove 25 are on the same horizontal line, it will be embedded in the limiting groove 25, which can effectively prevent the cardboard from pushing the extension plate 9 to move forward and avoid the cardboard shifting during drilling, resulting in a reduction in drilling accuracy.

[0038] Then start the first motor 5 to drive the worm 2102 to rotate, so that the two worm wheels 2101 can drive the two third threaded rods 22 to rotate synchronously, so that the two third threaded rods 22 can control the adjustment plate 14 to move back and forth in the adjustment groove 23 through the two threaded grooves 16, and rotate the second threaded rod 17 to one side to drive the moving block 19 to move in the moving groove 18, so that the drilling machine 15 can move back and forth and to both sides, facilitating the positioning of the drilling point of the drilling machine 15, effectively reducing the time wasted on positioning when using a hand-held drilling device for drilling, and making the drilling more stable. Then start the four electric telescopic rods 3 to contract to shorten the distance between the drilling machine 15 and the base 1, facilitating the drilling of the cardboard.

[0039] Working principle: When in use, it can clamp cardboard of different sizes according to the first threaded rod 11. At the same time, the limiting mechanism 20 and the extension plate 9 prevent the cardboard from slipping out of the front end of the base 1, avoiding the cardboard shaking during drilling. And it can adjust the position of the adjustment plate 14 in the adjustment groove 23 through the cooperation of the adjustment mechanism 21 and the third threaded rod 22. At the same time, the position of the moving block 19 in the moving groove 18 can be adjusted through the second threaded rod 17, so as to control the drilling machine 15 to move back and forth and to both sides, facilitating the adjustment of the drilling location, and preventing the use of a hand-held drilling tool for drilling from resulting in irregular holes and inaccurate positioning.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
