Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper box processing technology, and in particular to a box pressing tool. Background Technology
[0002] A cardboard box is a packaging container made primarily of cardboard, whiteboard paper, or corrugated paper, through folding and gluing processes. A cardboard box typically consists of a box body with an inner long fold, an outer long fold, and two short folds at one end. The inner long fold has an adhesive layer. The operator first stands the box upright so that the opening at one end faces upwards. Next, the operator folds the two short folds inwards along the crease line. Then, the operator folds the inner long fold inwards along the crease line. Finally, the operator folds the outer long fold inwards along the crease line, so that the outer long fold rests against the adhesive layer on the inner long fold, completing the folding and gluing of one end of the box. During the folding of the outer long fold, uneven force applied by the operator can lead to uneven contact between the outer and inner long folds and the adhesive layer, resulting in insufficient adhesion and reducing the structural strength of the cardboard box. Utility Model Content
[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a box-pressing fixture, which helps to ensure the structural strength of the paper box.
[0004] The pressing fixture according to an embodiment of the present utility model includes a worktable, a limiting plate, a lifting drive component, a pressing plate, and two limiting blocks.
[0005] A limiting plate is disposed on the worktable; two limiting blocks are disposed on the worktable, with the two limiting blocks respectively disposed on the left and right sides of the limiting plate. The worktable, the limiting plate, and the two limiting blocks enclose a limiting cavity for accommodating the box body of the paper box; a pressure plate is slidably connected to the worktable in the vertical direction, and the pressure plate is disposed above the limiting plate. The length of the pressure plate is greater than the length of the outer long fold of the paper box. The pressure plate is used to abut against the outer long fold to fold the outer long fold inward; a lifting drive is disposed on the worktable, and the output end of the lifting drive is connected to the pressure plate. The lifting drive can drive the pressure plate to descend, so that the outer long fold is folded inward and adhered to the adhesive layer of the inner long fold of the paper box.
[0006] It has at least the following beneficial effects:
[0007] When attaching the outer long fold of the cardboard box to the adhesive layer on the inner long fold, the operator first folds the two short folds at one end of the cardboard box inward along the crease line, and then folds the inner long fold inward along the crease line, so that the inner long fold overlaps the two short folds, with the adhesive layer on the inner long fold facing upward. Next, the operator places the cardboard box from back to front into the limiting cavity formed by the worktable, the limiting plate, and two limiting blocks. During the placement of the cardboard box into the limiting cavity, the outer long fold at one end of the cardboard box abuts against the pressure plate, and as the cardboard box moves forward, the outer long fold swings inward along the crease line. When the box body abuts against the limiting plate, the cardboard box is in position, and the two limiting blocks abut against the left and right sides of the box body, respectively, so that the limiting plate and the two limiting blocks simultaneously position the cardboard box, at which point the outer long fold remains abutted against the pressure plate. After the cardboard box is moved into position, the lifting drive causes the pressure plate to descend, causing the outer long fold to fold inward further and press against the adhesive layer on the inner long fold, thus completing the folding and bonding of the cardboard box. Because the length of the pressure plate is greater than the length of the outer long fold, it can completely cover the outer long fold when pressed down, ensuring that the entire length of the outer long fold is subjected to uniform pressure. This allows for even contact between the adhesive layer on the outer and inner long folds, ensuring sufficient adhesion between them and thus guaranteeing the structural strength of the cardboard box.
[0008] According to the pressing fixture of this utility model embodiment, the positions of the two limiting blocks in the left-right direction can be adjusted so that the length of the limiting cavity in the left-right direction can be adjusted.
[0009] The pressing fixture according to an embodiment of the present utility model further includes two first slide rails and two first sliders. The two first slide rails are parallel to the left and right directions and are both disposed on the worktable. The two first sliders are respectively disposed on the two limiting blocks and are respectively slidably connected to the two first slide rails.
[0010] The pressing fixture according to an embodiment of the present utility model further includes two first clamping components, which are respectively disposed on two first sliders, and both first sliders can be fixed on the worktable by the first clamping components.
[0011] According to the pressing fixture of this utility model embodiment, the first clamping component includes a screw and a gripping part. The first slider is provided with a threaded hole. The screw is threadedly connected to the wall of the threaded hole. The lower end of the screw can press against the worktable so that the first slider is fixed on the first slide rail. The gripping part is provided at the upper end of the screw.
[0012] According to the pressing fixture of this utility model embodiment, the first clamping component further includes a rubber pad, and the lower end of the screw abuts against the worktable through the rubber pad.
[0013] According to the pressing fixture of this utility model embodiment, the worktable is provided with a length scale parallel to the left and right direction, and both first sliders are provided with indicator arrows. Both indicator arrows are used to cooperate with the length scale to indicate the distance value between the two limiting blocks.
[0014] According to the pressing fixture of this utility model embodiment, the front ends of the two limiting blocks are provided with guide slopes, the included angle formed by the two guide slopes faces backward, and the two guide slopes are used to abut against the box body of the paper box.
[0015] According to the pressing fixture of this utility model embodiment, the position of the limiting plate in the front-back direction can be adjusted so that the length of the limiting cavity in the front-back direction can be adjusted.
[0016] The pressing fixture according to an embodiment of the present utility model further includes a second clamping component, two second slide rails and two second sliders. The two second slide rails are parallel to the front-back direction and are both disposed on the worktable. The two second sliders are both disposed on the limiting plate and are slidably connected to the two second slide rails respectively. The second clamping component is disposed on the limiting plate, and the limiting plate can be fixed on the worktable by the second clamping component.

[0032] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.
[0033] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0034] refer to Figures 1 to 5 This utility model discloses a box pressing fixture, including a worktable 300, a limiting plate 200, a lifting drive component 330, a pressing plate 320, and two limiting blocks 100.
[0035] A limiting plate 200 is mounted on a workbench 300; two limiting blocks 100 are also mounted on the workbench 300, located on the left and right sides of the limiting plate 200 respectively. The workbench 300, the limiting plate 200, and the two limiting blocks 100 together form a limiting cavity, which is used to accommodate the box body 10 of the paper box; a pressure plate 320 is slidably connected to the workbench 300 in the vertical direction, and is located above the limiting plate 200. The length of the pressure plate 320 is greater than the length of the outer long fold 20 of the paper box. The pressure plate 320 is used to abut against the outer long fold 20 so that the outer long fold 20 is folded inward. The lifting drive 330 is provided on the worktable 300. The output end of the lifting drive 330 is connected to the pressure plate 320. The lifting drive 330 can drive the pressure plate 320 to descend so that the outer long fold 20 is folded inward and glued to the adhesive layer 50 of the inner long fold 30 of the paper box.
[0036] In this embodiment of the invention, the workbench 300 is provided with two guide rods 310 parallel to the vertical direction, and the pressure plate 320 is provided with guide sleeves 321 on both the left and right sides. The two guide sleeves 321 can be slidably fitted onto the two guide rods 310 in the vertical direction, so that the pressure plate 320 can slide in the vertical direction. The length of the pressure plate 320 is greater than the length of the outer long fold 20 of the paper box, that is, the length of the pressure plate 320 in the horizontal direction is greater than the length of the outer long fold 20 in the horizontal direction, so that the outer long fold 20 can completely abut against the pressure plate 320. In this embodiment of the invention, the pressing fixture also includes a foot switch 350, and a lifting drive component 330 is a cylinder. The cylinder body is mounted on the frame, and the piston rod of the cylinder is connected to the pressing plate 320. The foot switch 350 is electrically connected to the cylinder. When the operator presses the foot switch 350, the cylinder drives the pressing plate 320 to descend. When the operator releases the foot switch 350, the cylinder drives the pressing plate 320 to rise. When the outer long fold 20 needs to be folded and glued, the operator presses the foot switch 350. After folding and gluing are completed, the operator releases the foot switch 350.
[0037] Understandably, when it is necessary to glue the outer long fold 20 of the cardboard box to the adhesive layer 50 on the inner long fold 30, the operator can first fold the two short folds 40 on one end of the cardboard box inward along the crease line, and then fold the inner long fold 30 inward along the crease line, so that the inner long fold 30 overlaps the two short folds 40, and the adhesive layer 50 on the inner long fold 30 faces upward. Next, the operator can place the cardboard box from back to front into the limiting cavity formed by the workbench 300, the limiting plate 200, and the two limiting blocks 100. During the process of placing the cardboard box into the limiting cavity, the outer long fold 20 on one end of the cardboard box can abut against the pressure plate 320, and as the cardboard box moves forward, the outer long fold 20 can swing inward along the crease line. When the box body 10 abuts against the limiting plate 200, the box moves into position. The two limiting blocks 100 abut against the left and right sides of the box body 10, respectively, so that the limiting plate 200 and the two limiting blocks 100 simultaneously position the box. At this time, the outer long fold edge 20 abuts against the pressure plate 320. After the box moves into position, the lifting drive 330 drives the pressure plate 320 to descend, so that the outer long fold edge 20 continues to fold inward and abuts against the adhesive layer 50 on the inner long fold edge 30, thereby completing the folding and gluing of the box. Since the length of the pressure plate 320 is greater than the length of the outer long fold 20, when the pressure plate 320 is pressed down, it can completely cover the outer long fold 20, ensuring that the outer long fold 20 is subjected to uniform pressure along its entire length. This allows the adhesive layer 50 on the outer long fold 20 and the inner long fold 30 to make uniform contact, thereby ensuring sufficient adhesion between the outer long fold 20 and the adhesive layer 50, thus guaranteeing the structural strength of the paper box.
[0038] refer to Figure 3 and Figure 4 The positions of the two limiting blocks 100 in the left-right direction are adjustable, allowing the length of the limiting cavity in the left-right direction to be adjusted as well. Understandably, in actual production, cardboard box sizes often vary. By adjusting the relative positions of the two limiting blocks 100 to change the length of the limiting cavity, the pressing fixture can adapt to cardboard boxes of different lengths, improving its versatility. The pressing fixture also includes two first slide rails 110 and two first sliders 120. Both first slide rails 110 are parallel to the left-right direction and are mounted on the worktable 300. The two first sliders 120 are respectively mounted on the two limiting blocks 100 and are slidably connected to the two first slide rails 110. Understandably, the two limiting blocks 100 are slidably connected to the two first slide rails 110 via the first sliders 120, allowing the operator to more smoothly adjust the positions of the two limiting blocks 100 in the left-right direction. Specifically, when the two limiting blocks 100 are far apart, the length of the limiting cavity in the left-right direction will increase; when the two limiting blocks 100 are close together, the length of the limiting cavity in the left-right direction will decrease.
[0039] refer to Figure 4 The pressing fixture also includes two first clamping components 130, which are respectively mounted on two first sliders 120. Both first sliders 120 can be fixed to the worktable 300 by the first clamping components 130. It is understood that after the operator adjusts the positions of the two limiting blocks 100, the two first sliders 120 can be fixed to the two first slide rails 110 by the first clamping components 130, thus preventing the limiting blocks 100 from shifting position during the operation of the pressing fixture. The first clamping component 130 includes a screw 131 and a gripping part 132. The first slider 120 has a threaded hole, and the screw 131 is threaded to the wall of the threaded hole. The lower end of the screw 131 can press against the worktable 300 to fix the first slider 120 on the first slide rail 110. The gripping part 132 is located at the upper end of the screw 131. Here, we take one of the first clamping components 130, the first slider 120, and the limiting block 100 as an example. It can be understood that the limiting block 100 can slide along the first slide rail 110 in the back-and-forth direction via the first slider 120. After the first slider 120 and the limiting block 100 are in position, the operator can tighten the screw 131, so that the lower end of the screw 131 presses against the worktable 300. Under the reaction force of the screw 131, the contact pressure between the first slider 120 and the first slide rail 110 increases, thus restricting the sliding of the first slider 120, thereby fixing the positions of the first slider 120 and the limiting block 100 and preventing positional displacement of the two limiting blocks 100 during the operation of the pressing fixture. On the other hand, the first slider 120 abuts against the worktable 300 via the screw 131, increasing the friction between the first slider 120 and the worktable 300, thereby preventing positional displacement of the first slider 120 and the limiting block 100. The upper end of the screw 131 is provided with a gripping part 132, which allows the operator to rotate the screw 131, improving the ease of rotation for the operator. The first tightening assembly 130 also includes a rubber pad 133, through which the lower end of the screw 131 abuts against the worktable 300 to prevent the lower end of the screw 131 from scratching the worktable 300.
[0040] refer to Figure 3 and Figure 4The worktable 300 has a length scale 340 parallel to the left and right directions. Each of the two first sliders 120 has an indicator arrow 140, which works in conjunction with the length scale 340 to indicate the distance between the two limiting blocks 100. It can be understood that the indicator arrows 140 on both first sliders 120 can work in conjunction with the length scale 340 to more intuitively and accurately display the distance between the two limiting blocks 100. When adjusting the position of the two limiting blocks 100, the operator can precisely adjust them to the desired position according to the indications of the length scale 340 and the two indicator arrows 140, thereby ensuring that the length of the limiting cavity in the left and right directions precisely matches the width of the cardboard box. On the other hand, operators do not need additional measuring tools to determine the distance between the two limit blocks 100. They can quickly determine the current position of the two limit blocks 100 and the distance between them simply by observing the relative position of the indicator arrow 140 and the length scale 340, saving operators time in adjusting the position of the two limit blocks 100. Specifically, the scale value of the length scale 340 gradually increases from left to right. Operators can first observe the value of the length scale 340 corresponding to the indicator arrow 140 on the two first sliders 120, and then subtract the scale value corresponding to the left limit block 100 from the scale value corresponding to the right limit block 100. The difference is the distance between the two limit blocks 100. This will not be elaborated further here.
[0041] refer to Figure 4 Each of the two limiting blocks 100 has a guide ramp 150 at its front end. The included angle formed by the two guide ramps 150 faces backward, and the two guide ramps 150 are used to abut against the box body 10 of the cardboard box. It can be understood that the two guide ramps 150 can abut against the box body 10 of the cardboard box, so that the two guide ramps 150 can guide the box body 10 of the cardboard box, thereby allowing the box body 10 of the cardboard box to smoothly enter the limiting cavity.
[0042] refer to Figure 5 and Figure 6The position of the limiting plate 200 in the front-back direction is adjustable, so that the length of the limiting cavity in the front-back direction can also be adjusted. It is understandable that in actual production, the size of cardboard boxes often varies. By adjusting the position of the limiting plate 200 in the front-back direction, the width of the limiting cavity, i.e., the length of the limiting cavity in the front-back direction, can be adjusted, allowing the pressing fixture to adapt to cardboard boxes of different widths, thus improving the versatility of the pressing fixture. The pressing fixture also includes a second clamping assembly 210, two second slide rails, and two second sliders. Both second slide rails are parallel to the front-back direction and are both mounted on the worktable 300. Both second sliders are mounted on the limiting plate 200 and are slidably connected to the two second slide rails respectively. The second clamping assembly 210 is mounted on the limiting plate 200, and the limiting plate 200 can be fixed to the worktable 300 by the second clamping assembly 210. The second slide rail and the second slider have the same function as the first slide rail 110 and the first slider 120. The second clamping assembly 210 has the same function and structure as the first clamping assembly 130, which will not be described further here.
[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0044] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
