Description

Technical Field

[0001] The utility model relates to the technical field of paper box packaging fixing equipment, in particular to a fixing device for paper box packaging. Background Art

[0002] Carton packaging is largely used to promote and beautify products with its exquisite shape and decoration. There are many styles and types. During the processing of the carton, the cardboard needs to be fixed and then processed to form a carton. When processing the cardboard, multiple identical cardboards are often stacked together and then processed uniformly. During this process, the cardboard needs to be fixed.

[0003] Chinese Patent Publication No. CN217862988U relates to a fixing device for the production and processing of packaging cardboard boxes, which solves the problem in the prior art of directly using a clamp to fix it, but the clamp is inconvenient to adjust, resulting in inconvenience in adapting to different sizes of cardboard for use, and having great limitations in actual use. A fixing device for the production and processing of packaging cardboard boxes, comprising an operating table and a base, the base being rotatably connected to the top of the operating table, the top of the base being slidably connected to four connecting frames, and the four connecting frames being grouped in pairs. The utility model can press and fix the cardboard box according to the size of the cardboard box by arranging a first screw, a base, a connecting frame, a vertical rod, etc., and the position of the cardboard box can be adjusted before pressing by using the connecting frame and the vertical rod, so that multiple cardboards are more neat when stacked together, thereby achieving the purpose of improving the practicality of the device.

[0004] When fixing the paper box, the above patent needs to move the vertical rod in four directions respectively until the distance between the two opposite long boards is greater than the width of the paper box, so that the paper box can be placed inside the device, and then the vertical rod is moved inward so that the bottom surface of the long board corresponds to the upper end surface of the paper box, and then the long board is pushed downward. Only then can the paper box be fixed. This method is relatively cumbersome, and the movement of the vertical rod takes a long time. In addition, since the movement of the four long boards is controlled by four motors respectively, it not only increases energy consumption, but also easily causes the four long boards to slide down at different distances, resulting in bending of the cardboard.

DETAILED DESCRIPTION

[0026] The present invention will be described in further detail below with reference to the accompanying drawings.

[0027] Example:

[0028] Reference Figure 1-Figure 5 The utility model discloses a fixing device for carton packaging, comprising a base 1, a fixed vertical rod 2 is provided on the outer peripheral wall of the base 1, a rotating groove 3 is provided inside the fixed vertical rod 2, and a driving screw 4 is provided inside the rotating groove 3;

[0029] A slide rod 5 is provided inside the rotating groove 3. A screw hole 6 is provided at one end of the slide rod 5 to cooperate with the driving screw 4. A deflection groove 7 is provided on the top side wall of the rotating groove 3. A cylindrical shell 8 is provided at one end of the slide rod 5. The interior of the slide rod 5 is hollow and communicates with the cylindrical shell 8.

[0030] The inner cavity wall of the cylindrical shell 8 is provided with two installation shafts 9, and the outer peripheral sides of the two installation shafts 9 are provided with two straight rods 10 opposite to each other. The side wall of the slide rod 5 is provided with a compression mechanism 11, and the interior of the slide rod 5 is provided with a driving push rod 12.

[0031] When the cardboard is needed to be fixed on the upper end of the base 1, the sliding rod 5 is pushed upward by rotating the driving screw 4 so that the sliding rod 5 contacts the top of the rotating groove 3. At this time, the sliding rod 5 is blocked by the top of the fixed vertical rod 2 and cannot continue to rotate. Then, the sliding rod 5 will follow the driving screw 4 to deflect and deflect to the inside of the deflection groove 7. At this time, there is no obstruction above the base 1 and the sliding rod 5 is at the top of the device, which can effectively facilitate the placement of the cardboard on the upper end of the base 1.

[0032] After the cardboard is placed, the screw rod 4 is driven to rotate in the opposite direction, so that the slide rod 5 is deflected to the inside of the rotating groove 3 again and moves downward, so that the bottom end of the slide rod 5 contacts the upper end of the cardboard to achieve the purpose of fixing the cardboard. When the slide rod 5 moves from the inside of the deflection groove 7 to the inside of the rotating groove 3, the compression mechanism 11 is compressed to push the air inside the slide rod 5, so that the driving push rod 12 moves and the straight rods 10 on both sides are expanded to both sides. Figure 1 and Figure 3 As shown, the expansion area of ​​the device on the upper end of the cardboard is increased by expanding the straight rod 10 to improve the stability of the fixed cardboard, and when the slide rod 5 is inside the deflection groove 7, the compression mechanism 11 is in the original state and cannot push the driving push rod 12 to move. Therefore, the straight directions of the straight rods 10 on both sides are the same, as shown in FIG. Figure 2 and Figure 4 As shown, the problem of the straight rod 10 blocking the top of the base 1 can be effectively avoided.

[0033] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the compression mechanism 11 includes a through groove 111, and a rotating shaft 112 is provided at one end of the inner part of the through groove 111. The through groove 111 is opened on the outer wall of the sliding rod 5 on the side close to the driving screw 4. The outer surface of the rotating shaft 112 is provided with a fan-shaped rotating plate 113, and the outer wall of the fan-shaped rotating plate 113 is in contact with the groove wall of the through groove 111.

[0034] In this embodiment, the through groove 111 is provided for installing the rotating shaft 112, and the fan-shaped rotating plate 113 is installed through the rotating shaft 112. Since the side wall of the fan-shaped rotating plate 113 fits with the groove wall of the through groove 111, it can effectively prevent the air inside the slide rod 5 from being discharged through the through groove 111. When the slide rod 5 is located inside the rotating groove 3, the fan-shaped rotating plates 113 fit with the side walls of the rotating groove 3. When the fan-shaped rotating plate 113 is not subjected to force, that is, the side walls of the slide rod 5 do not contact the side walls of the rotating groove 3, the air pressure inside the slide rod 5 is slightly greater than one atmospheric pressure, so that the fan-shaped rotating plate 113 can be pushed out of the through groove 111. Figure 2 and Figure 4 As shown, when the slide rod 5 moves from the inside of the deflection groove 7 to the rotation groove 3, the side wall of the fan-shaped rotation plate 113 can be effectively pressed by the side wall of the rotation groove 3 to push the fan-shaped rotation plate 113 into the interior of the slide rod 5.

[0035] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the driving push rod 12 includes a pneumatic piston 121 , an extension push rod 122 is provided at one end of the pneumatic piston 121 facing the cylindrical housing 8 , and rack plates 123 are provided on both sides of the extension push rod 122 .

[0036] In this embodiment, through the setting of the pneumatic piston 121, when the fan-shaped rotating plate 113 is pressed into the interior of the slide rod 5, the air pressure inside the slide rod 5 will increase, thereby pushing the pneumatic piston 121 to move it to one end, thereby moving the rack plates 123 on both sides, and a return spring is provided at the end of the extended push rod 122 to achieve the effect of causing the pneumatic piston 121 to rebound when the slide rod 5 moves from the rotating groove 3 to the inside of the deflection groove 7.

[0037] In a further preferred embodiment of the present invention, Figure 1-5 As shown, a half-toothed ring 101 is provided on the outer surface of one end of the two straight rods 10 , and the two half-toothed rings 101 are respectively engaged with the rack plates 123 on both sides of the extension push rod 122 .

[0038] In this embodiment, the rack plate 123 moves in coordination with the half gear ring 101 to effectively push the straight rods 10 on both sides to rotate, so that the straight rods 10 on both sides can be deflected to achieve the purpose of opening the straight rods 10.

[0039] In a further preferred embodiment of the present invention, Figure 1-5 As shown, a support plate 51 is provided inside the slide rod 5 at a position corresponding to the fan-shaped rotating plate 113, and guide rails 52 are provided inside the slide rod 5 and on both sides of the pneumatic piston 121, and a gap 53 for the pneumatic piston 121 to slide is provided between the two guide rails 52.

[0040] In this embodiment, the support plate 51 is provided to limit the deflection of the fan-shaped rotating plate 113, thereby preventing the fan-shaped rotating plate 113 from being out of contact with the through groove 111, thereby preventing the problem of air leakage inside the slide rod 5. The two guide rails 52 are provided to locate the position of the pneumatic piston 121 and achieve the purpose of guiding the pneumatic piston 121, thereby achieving the purpose of improving the stability of the pneumatic piston 121.

[0041] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the bottom ends of the two straight rods 10 are flush with the bottom end wall of the cylindrical shell 8.

[0042] In this embodiment, since the bottom end of the straight rod 10 is flush with the bottom end wall of the cylindrical shell 8, the contact surface between the device and the top surface of the cardboard is a plane, which can effectively avoid the problem of bending the cardboard.

[0043] In a further preferred embodiment of the present invention, Figure 1-5 As shown, a driving motor is provided at the inner bottom end of the fixed vertical rod 2 , and the motor shaft of the driving motor is connected to the driving screw 4 .

[0044] In this embodiment, the driving motor is configured to control the rotation of the driving screw 4 .

[0045] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
