Description

Technical Field

[0001] This utility model belongs to the field of paper box forming technology, and in particular relates to a paper box frame device. Background Technology

[0002] Packaging boxes are generally made by folding cardboard into shape and then attaching a face paper to the outer surface of the formed frame. Currently, some packaging boxes use strips of cardboard with multiple creases to form a frame structure, with an adhesive face paper attached to the outer surface of the frame. The edges of the face paper are folded back to secure the frame, and a bottom paper is then attached to the bottom of the frame, thus forming the box frame. For example, Chinese patent document CN114311844B discloses a method for assembling a box with a frame. An unfolded strip ultimately forms a shaped frame with its ends joined together, defined as the first frame. An unfolded strip can be divided into five segments: a first segment, a second segment, a third segment, a fourth segment, and a fifth segment. After the strip surrounds and forms the inner mold, the strip constitutes the frame, defined as the first frame. The second section of the webbing is tightly attached to the first surface of the inner mold, forming the first surface of the frame; the third section of the webbing is tightly attached to the second surface of the inner mold, forming the second surface of the frame; the fourth section of the webbing is tightly attached to the third surface of the inner mold, forming the third surface of the frame; the first and fifth sections of the webbing are tightly attached to the fourth surface of the inner mold, and together they form the fourth surface of the frame. In other words, after an unfolded webbing forms a shaped frame with its ends joined together, it becomes the first frame. The first frame has four surfaces: the first surface, the second surface, the third surface, and the fourth surface, wherein the first and fifth sections of the webbing together form the fourth surface. A boxing device is also provided to realize the webbing frame.

[0003] Chinese invention patent document CN109986835B discloses a frame forming mechanism that achieves automatic frame forming. Specifically, it includes a forming mold, a feeding flap, two side forming devices, and a rear forming device. The forming mold is characterized by a suction device connected to it, which includes a first suction nozzle located at the front of the forming mold. The feeding flap is positioned in front of the forming mold and connected to a flipping transmission device. The two side forming devices include a left-side folding device and a right-side folding device, with the left-side folding device positioned on the left side of the forming mold and the right-side folding device positioned on the right side. The rear forming device includes a cardboard folding device and a face paper folding device, with the cardboard folding device and the face paper folding device positioned at the rear of the forming mold. The left-side folding device includes a left-side folding component (such as a brush or rubber roller), which is connected to the left support. The left support is connected to the left-side forward and backward moving transmission device. The left-side forward and backward moving transmission device drives the left support to move forward and backward. When moving backward, the left-side folding component on the left support folds the left side of the material being sucked up (the left side consists of two cardboard areas) towards the left side of the forming mold. The left-side forward and backward moving transmission device can be an electric cylinder or a linear module equipped with a power source (such as a motor). Further optimization can be achieved by installing a left lifting plate on the left support, equipped with a left lifting drive device. The left lifting drive device drives the left lifting plate to rise and fall on the left support. The left lifting drive device can be a cylinder or an electric cylinder or linear module with a power source (such as a motor). The components on the left lifting plate will also rise and fall with the left lifting plate. After the left lifting plate rises, it moves back and forth with the left support to pass over the flipped-up feeding flap below and the flipped material. It can also cooperate with the corresponding feeding device to transport materials to the feeding flap. After descending, it moves backward to perform a folding action. Of course, it is also possible to eliminate the need for a left lifting plate, move the left support forward to position first, and then have the feeding flap flip forward to stand the material up. If a left lifting plate is installed, the left folding component can be connected to the left lifting plate of the left support. For further optimization, the left lifting plate will also be equipped with a left extension transmission device, which is connected to the left folding component. The left extension transmission device can drive the left folding component to extend and retract. The left extension transmission device can be a cylinder, an electric cylinder with a power source (such as a motor), or a linear module. When extending, the left folding component moves backward to perform the folding operation. After retracting, the left folding component can return to its forward position to wait for the next operation. The left folding component will not come into contact with the material again after retracting and returning to its forward position. Of course, the left extension transmission device can also be omitted, and the left folding component will apply pressure to the material when moving backward and forward.Further optimization involves connecting the left-side folding device to the first left-right adjusting frame. The left-side folding device is positioned on the first left-right adjusting frame, which is configured and connected to the left and right tracks of the machine frame (such as guide rails or guide rods set in the left and right directions). By adjusting the left and right positions of the first left-right adjusting frame on the left and right tracks, the position of the left-side folding device can be adjusted to meet the production needs of different specifications of the frame. The first left-right adjusting frame on the left and right tracks can be adjusted manually by a lead screw and nut mechanism, an electric lead screw and nut mechanism, or directly by manual flat pushing.

[0004] The right-side folding device includes a right-side folding component (such as a brush or rubber roller), which is connected to the right support. The right support is connected to the right front-back moving transmission device, which drives the right support to move back and forth. When moving backward, the right-side folding component on the right support folds the right side of the material being sucked up (the right side is an area where another cardboard area and the face paper are misaligned) towards the right side of the forming mold. The right front-back moving transmission device can be an electric cylinder or a linear module equipped with a power source (such as a motor). Further optimization can be achieved by installing a right lifting plate on the right support, equipped with a right lifting drive device. The right lifting drive device can drive the right lifting plate to rise and fall on the right support. The right lifting drive device can be a cylinder or an electric cylinder or linear module with a power source (such as a motor). The components on the right lifting plate will also rise and fall with the right lifting plate. After the right lifting plate rises, it moves back and forth with the right support to pass over the flipped-up feeding flap below and the flipped material. It can also cooperate with the corresponding feeding device to transport materials to the feeding flap. After descending, it moves backward to perform a folding action. Of course, it is also possible to eliminate the need for a right lifting plate, move the right support forward to position first, and then have the feeding flap flip forward to stand the material up. If a right lifting plate is installed, the right folding component can be connected to the right lifting plate of the right support. Further optimization involves installing a right extension transmission device on the right lifting plate, which is connected to the right folding component. This device can drive the right folding component to extend and retract. The right extension transmission device can be a cylinder, an electric cylinder with a power source (such as a motor), or a linear module. When extending, the right folding component moves backward to perform the folding operation. After retracting, the right folding component can return to its forward position to await the next operation. Returning to its forward position after retraction prevents the right folding component from contacting the material again. Alternatively, the right extension transmission device can be omitted; in this case, both backward and forward movement of the right folding component will apply pressure to the material. The right support is connected to the right front-to-back moving transmission device, which is connected to the second left-to-right adjusting frame. The right-side folding device is located on the second left-to-right adjusting frame. The second left-to-right adjusting frame is configured and connected to the left and right tracks of the frame (such as guide rails or guide rods set in the left and right directions, which can share the left and right tracks with the first left-to-right adjusting frame or be set separately). By adjusting the left and right position of the second left-to-right adjusting frame on the left and right tracks, the position of the right-side folding device can be adjusted to meet the production needs of different specifications of the frame. The second left-to-right adjusting frame on the left and right tracks can be adjusted manually by a lead screw and nut mechanism, an electric lead screw and nut mechanism, or directly by manual flat push adjustment.

[0005] As can be seen, the technical solution disclosed in the aforementioned patent documents utilizes left and right folding devices to fold the frame strips to both sides of the frame mold. Its structure is relatively complex, requiring multiple movements during folding, resulting in rather low frame efficiency. Utility Model Content

[0017] The above-mentioned one or more technical solutions in the cardboard box frame device provided in this embodiment of the utility model have at least the following technical effects:

[0018] This utility model discloses a cardboard box framing device. A framing strip with a face paper attached to its bottom is positioned above the forming groove of a support plate. A lifting drive mechanism lowers the framing mold, causing the framing strip to adhere to the bottom side of the mold. As the mold continues to descend, the framing strip descends along the forming groove. Simultaneously, under the combined action of the mold and the forming groove, the two sides of the framing strip fold over, thus wrapping the framing strip around the bottom and sides of the mold. When the mold reaches its lowest point, a translation mechanism drives a pressing plate to move horizontally. The pressing plate folds the vertical portion of the framing strip to the top side of the mold, thus wrapping the framing strip around the mold and completing the framing process.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0029] In one embodiment of the paper box frame device of this utility model, please refer to... Figures 1 to 5 The cardboard box framing device includes a machine base 100, a framing forming fixture 200, and a framing strip positioning and forming device 300. The framing forming fixture 200 includes a mounting base 210, a lifting drive component 220, and a framing mold 230. The mounting base 210 is mounted on the machine base 100, the lifting drive component 220 is mounted on the mounting base 210, and the framing mold 230 is mounted on the lifting drive component 220. The lifting drive component 220 drives the framing mold 230 to move up and down. Limiting components 240 are provided on both sides of the lower end of the movement trajectory of the framing mold 230 to limit the cardboard on both sides of the framing mold 230. Specifically, a guide rail is provided on the outer side of the mounting base 210, and the framing mold 230 is connected to the guide rail. The lifting drive component 220 can be an electric screw mechanism or a cylinder.

[0030] Reference Figure 4 and Figure 5The frame strip positioning and forming device 300 includes a support base 310, a support plate 320, a translation mechanism 330, and a pressing plate 340. The support base 310 is mounted on the machine base 100, and the support plate 320 is mounted on the support base 310 to support the frame strip. The support plate 320 has a forming groove 321 on the side near the frame forming fixture 200 to allow the frame mold 230 to move vertically, and the frame strip is folded upwards by the two side walls of the forming groove 321 and the frame mold 230. The translation mechanism 330 is located on one side of the support base 310, and the pressing plate 340 is mounted on the translation mechanism 330 to push the frame strip to bend and adhere it to the top side of the frame mold 230. Specifically, the frame strip with a face paper attached to its bottom is positioned above the forming groove 321 of the support plate 320. The lifting drive 220 drives the frame mold 230 to descend, causing the frame strip to adhere to the bottom side of the frame mold 230. As the frame mold 230 continues to descend, the frame strip descends along the forming groove 321. Simultaneously, under the combined action of the frame mold 230 and the forming groove 321, the sides of the frame strip fold over, thus wrapping the frame strip around the bottom and sides of the frame mold 230. When the frame mold 230 descends to its lowest point, the translation mechanism 330 drives the push plate 340 to translate. The push plate 340 folds the vertical part of the frame strip to the top side of the frame mold, thus wrapping the frame strip around the frame mold and completing the frame. Preferably, the translation mechanism 330 can be a linear module such as an electric screw mechanism or a cylinder. Preferably, rollers 322 are provided on both sides of the forming groove 321 to facilitate the forming of the frame strip. The rollers 322 are rotatably connected to the support plate 320. Therefore, the contact between the frame strip and the roller 322 is a rolling contact, reducing wear during frame strip forming. This carton frame device utilizes the cooperation between the frame mold 230 and both sides of the forming groove 321 to fold the frame strip, and then uses the translation mechanism 330 to drive the push plate 340 to push one end of the frame strip to the top side of the frame mold 230, completing the frame. Compared to existing frame equipment, this design is simpler and more efficient.

[0031] More preferably, please refer to Figure 4 and Figure 5 The forming groove 321 has downward-extending guide plates 323 on both sides; and an extrusion groove is formed between the two guide plates 323. The guide plates 323 limit the frame strip, allowing it to better fit against both sides of the frame mold 230. Furthermore, the inner side of the guide plates 323 is provided with a limiting groove 324 to limit the width of the frame strip. Specifically, the limiting groove 324 limits the frame strip, preventing misalignment and improving the accuracy of the frame.

[0032] Further, refer to Figure 2 and Figure 3The mounting base 210 has a mounting plate 250 at its bottom end, and two limiting members 240 are mounted on the mounting plate 250. Each limiting member 240 includes a flat pusher 241 and a limiting block 252. The flat pusher 241 is mounted on the mounting plate 250, and the limiting block 252 is located at the telescopic end of the flat pusher 241. The inner side of the limiting block 252 has a limiting groove 253 that mates with the frame mold 230. The mounting plate 250 also has a limiting seat 260, with a limiting step 261 extending upwards on the side of the limiting seat 260 away from the frame mold 230. In this embodiment, when the frame mold 230 pushes the frame strip to its lowest point, the bottom of the frame strip is limited by the limiting seat 260. The flat pusher 241 drives the limiting block 252 to press the frame strip tightly against both sides of the frame mold 230, thus positioning and forming the frame strip on the frame mold 230.

[0033] Furthermore, refer to Figure 4 and Figure 5 The support plate 320 is also provided with a face paper folding mechanism 350 for folding a face paper to the frame strip. The face paper folding mechanism 350 includes a fixed baffle 351, a movable baffle 352, and a pusher 353. The fixed baffle 351 is disposed on the support plate 320, and the movable baffle 352 is slidably disposed on the support plate 320. A positioning groove 354 is formed between the movable baffle 352 and the fixed baffle 351. The bottom side of the movable baffle 352 forms a clearance gap with the support plate 320, and the bottom of the movable baffle 352 forms a pushing surface. The pusher 353 is connected to the movable baffle 352 and is used to push the movable baffle 352 to translate. Specifically, in this embodiment, a face paper is attached to the bottom of the frame strip, and the two sides of the face paper exceed the width of the frame strip. A robotic arm or similar mechanism picks up the frame strip with the face paper attached and places it into the forming and positioning groove 354. Under the action of the movable baffle 352 and the fixed baffle 351, the edge of the face paper extending from the bottom of the frame strip is bent upwards and fits against the side wall of the forming and positioning groove 354. The face paper portion bent by the fixed baffle 351 forms the bottom support of the frame, facilitating the subsequent application of the bottom paper. The portion that fits against the movable baffle 352 is pushed to translate by the pusher 353, causing the extrusion surface at the bottom of the movable baffle 352 to press the upwardly bent face paper, thereby folding the face paper portion back and fitting it against the top side of the frame strip, thus completing the top edge binding of the frame.

[0034] Furthermore, please refer to Figure 4 and Figure 5The movable baffle 352 includes a translation plate 3520, a flipping plate 3521, and a flipping drive member 3522. The translation plate 3520 is slidably connected to the support plate 320, a pusher 353 is connected to the translation plate 3520, the flipping plate 3521 is rotatably connected to the translation plate 3520, and the flipping drive member 3522 is connected to the flipping plate 3521 to drive the flipping plate 3521 to rotate. The extrusion surface is located on the bottom side of the flipping plate 3521. Specifically, after the face paper is attached to the top side of the frame strip, the flipping drive member 3522 drives the flipping plate 3521 to rotate upward, thereby preventing the face paper from being torn or the face paper attached to the top side of the frame strip from being lifted when the movable baffle 352 retracts. Specifically, the flipping drive 3522 is a cylinder located on the bottom side of the translation plate 3520, and an eccentric part extends from one side of the folding plate 3521 and is connected to the cylinder. The eccentric part is pulled by the cylinder to flip the folding plate 3521 upward.

[0035] Furthermore, refer to Figure 4 and Figure 5 The frame strip positioning and forming device 300 also has a pusher mechanism 400 on one side, which is used to push the vertical face paper on one side of the frame mold to adhere to the top side of the frame. Specifically, one end of the face paper attached to the bottom of the frame strip extends beyond the frame strip in the length direction. When the frame strip is completed, one end of the face paper is vertically located on one side of the frame. The pusher mechanism 400 pushes the face paper to bend and adhere to the top side of the frame strip, thereby achieving the bonding and fixing of the two ends of the frame. Specifically, the pusher mechanism 400 includes a second support base 410, a telescopic member 420, and a flat push plate 430. The second support base 410 is mounted on the machine base 100, the telescopic member 420 is a cylinder mounted on the second support base 410, and the flat push plate 430 is located at the telescopic end of the telescopic member 420. The telescopic component 420 pushes the flat push plate 430 to move horizontally, thereby causing the flat push plate 430 to push the face paper flat and adhere it to the top side of the frame, thus bonding and fixing the two sides of the frame and fixing the two ends of the frame.

[0036] Furthermore, refer to Figure 4 The moving end of the translation mechanism 330 is also equipped with a lifting cylinder 360, and a pressing plate 340 is mounted on the lifting cylinder 360. In this embodiment, when the pressing plate 340 pushes the frame plate to fold to the top side of the frame mold 230, the lifting cylinder 360 drives the pressing plate 340 to descend, so that the pressing plate 340 can press the frame strip against the top side of the frame mold 230, thereby pressing the frame strip tightly and forming it on the top side of the frame mold 230. When the pressing plate 340 resets, the lifting cylinder 360 drives the pressing plate 340 to rise, avoiding contact between the pressing plate 340 and the top side of the frame strip.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
