Description

Technical Field

[0001] This application relates to a paper box folding mechanism, and more particularly to a paper box folding mechanism with a measurement and adjustment function. Background Technology

[0002] Cardboard boxes are an indispensable packaging tool in modern logistics and transportation. Airplane boxes, a type of cardboard box made from corrugated cardboard, are highly cost-effective and widely used in product packaging and express delivery. Existing cardboard box folding mechanisms typically include a folding frame and a support structure mounted on the folding frame. During the folding process, the unfolded cardboard box is first placed on the folding mechanism, and then pressed down, causing the unfolded box to fold into shape under the guidance and support of the support structure.

[0003] like Figure 1 The diagram illustrates a typical cardboard box unfolding structure. The cardboard 3 includes: a base plate 31, a front support plate 32, a rear support plate 33, a second flap 35, a first flap 34, side wings 36, flaps 37, a top cover 38, and a closing plate 39. In this typical cardboard box unfolding structure, depending on the manufacturer or supplier, gaps 30 may or may not exist between the side wings 36 and the second flap 35, or between the side wings 36 and the first flap 34, depending on the raw materials provided by the cardboard box manufacturer. If gaps 30 exist between the side wings 36 and the second flap 35, or between the side wings 36 and the first flap 34, the support structure in the cardboard box folding mechanism may become stuck in these gaps during the folding process, causing jamming and preventing the folding mechanism from continuing to fold the cardboard box.

[0021] Please see Figure 1 and Figure 2 This application provides a cardboard box folding mechanism, which is mainly used to fold cardboard 3 to form an airplane box. Cardboard 3 includes: a base plate 31, a front support plate 32, a rear support plate 33, a first flap 34, a second flap 35, side wings 36, flaps 37, a top cover 38, and a closing plate 39.

[0022] Specifically, the front support plate 32 and the rear support plate 33 are respectively connected to the two long sides of the base plate 31. The first flap 34 has a first end face 340, and the second flap 35 has a second end face 350, with the first end face 340 and the second end face 350 facing each other. Two flaps are provided for each of the second flap 35, the first flap 34, the side wings 36, and the flaps 37, and the two side wings 36 are respectively connected to the two short sides of the base plate 31. The two second flaps 35 are respectively connected to the two short sides of the front support plate 32, and the two first flaps 34 are respectively connected to the two short sides of the rear support plate 33. The other long side of the rear support plate 33 and one long side of the cover plate 39 are respectively connected to the two long sides of the top cover 38. The two flaps 37 are respectively connected to the two short sides of the top cover. Fold lines are provided at the points where the base plate 31, front support plate 32, rear support plate 33, first flap 34, second flap 35, side wing 36, flap 37, top cover 38, and closing cover plate 39 are connected to each other, so as to bend during folding.

[0023] Please continue reading. Figure 1 and Figure 2 The two ends of the side wing 36 are adjacent to the second flap 35 and the first flap 34, respectively. There are gaps 30 between the side wing 36 and the second flap 35, and between the side wing 36 and the first flap 34. Due to the presence of gaps 30, during the folding of the cardboard 3 to form the airplane box, the first support device 21 is very likely to get stuck in the gaps 30, causing the airplane box to be unable to be pressed down (e.g., ...). Figure 2 As shown, the folding operation of the airplane box cannot be completed. If further folding is required, the airplane box must be removed, repositioned, and then folded again. During the removal of the airplane box, the supporting part of the first supporting device 21 will also abut against the first flap 34, obstructing the removal operation and causing difficulty in removal. Simultaneously, the outer wall of the airplane box is easily scratched by the supporting part during removal, resulting in scratches on the outer wall of the airplane box. Therefore, during the folding process of the airplane box, it is necessary to ensure that the first supporting device 21 and the gap 30 are misaligned so that the first supporting device 21 supports and assists in the folding of the first flap 34. It should be noted that... Figure 2 The dashed line represents the fold line of cardboard 3.

[0024] Please see Figures 1 to 11 In one embodiment, the cardboard box folding mechanism includes a folding guide frame 1 and a support structure 2. The support structure 2 is connected to the folding guide frame 1, and its supporting side extends away from the folding guide frame 1. Multiple support structures 2 are provided, and these multiple support structures 2 surround a folding area A. The bottom plate 31 of the cardboard 3 is placed on the folding area A and pressed towards the folding guide frame 1. The support structures 2 assist in folding the front support plate 32, rear support plate 33, first flap 34, second flap 35, side wings 36, flaps 37, top cover 38, and closing plate 39, thereby forming an airplane box.

[0025] Please see Figure 1 , Figures 3 to 12 and Figure 15 In one embodiment, the support structure 2 includes: a first support device 21, a second support device 22, a first ranging block 23, and a second ranging block 24.

[0026] Specifically, the first support device 21 is connected to the folding guide frame 1. The second support device 22 is also connected to the folding guide frame 1, and the second support device 22 can slide relative to the folding guide frame 1, thereby moving away from or closer to the first support device 21. The first ranging block 23 is mounted on the first support device 21 and extends away from the folding area A. The second ranging block 24 is mounted on the second support device 22 and extends away from the folding area A. The second ranging block 24 can move synchronously with the second support device 22.

[0027] It should be noted that when adjusting the relative positions of the first support device 21 and the second support device 22, the first measuring block 23 and the second measuring block 24 cooperate to press the first measuring block 23 against the second end face 350 of the second flap 35 and the second measuring block 24 against the first end face 340 of the first flap 34. This facilitates adjusting the distance D between the first reference surface 21a of the first support device 21 and the second reference surface 22a of the second support device 22 to be the same as the distance W between the first flap 34 and the second flap 35 located on the same side.

[0028] Specifically, in this embodiment, when adjusting the distance D between the first reference surface 21a of the first support device 21 and the second reference surface 22a of the second support device 22, the cardboard 3 needs to be folded first, so that the second flap 35 and the first flap 34 on the same side protrude from the cardboard 3; then, the second end face 350 of the second flap 35 is pressed against the first measuring end face 230 of the first measuring block 23; subsequently, the second support device 22 is adjusted, and the second measuring block 24 is moved by the second support device 22, so that the second measuring end face 240 of the second measuring block 24 is pressed against the first end face 340 of the first flap 34; finally, the second support device 22 is fixed in the adjusted position, thus completing the adjustment of the support structure 2.

[0029] Obviously, by utilizing the principle of vernier caliper measurement and through the arrangement of the first measuring block 23 and the second measuring block 24, the carton folding mechanism can directly adjust the relative positions of the first support device 21 and the second support device 22 based on the distance W between the first flap 34 and the second flap 35. This ensures that the distance D between the first reference surface 21a of the first support device 21 and the second reference surface 22a of the second support device 22 is equal to the distance W. This design avoids the cumbersome operation of measuring the distance W and then adjusting the distance D, thus improving the simplicity and speed of the adjustment mechanism.

[0030] Please continue reading. Figure 1 , Figures 3 to 12 and Figure 15 In other embodiments, when adjusting the distance D between the first reference surface 21a of the first support device 21 and the second reference surface 22a of the second support device 22, the first end face 340 of the first flap 34 can be pressed against the first measuring end face 230 of the first measuring block 23; then the second support device 22 is adjusted, and the second measuring block 24 is moved by the second support device 22, so that the second measuring end face 240 of the second measuring block 24 abuts against the second end face 350 of the second flap 35; finally, the second support device 22 is fixed in the adjusted position, thus completing the adjustment of the support structure 2.

[0031] In one embodiment, the first measuring end face 230 of the first measuring block 23 and the second measuring end face 240 of the second measuring block 24 are arranged parallel to each other. This not only facilitates the insertion of the first measuring block 23 and the second measuring block 24 between the first flap 34 and the second flap 35, but also improves the accuracy of distance adjustment and ensures the smoothness of the paper box folding process after the paper box folding mechanism is adjusted. It should be noted that in this embodiment, the first measuring block 23 is arranged perpendicularly to the first support device 21, and the second measuring block 24 is arranged perpendicularly to the second support device 22.

[0032] In one embodiment, the distance between the first measuring block 23 and the folding guide bottom frame 1 and the distance between the second measuring block 24 and the folding guide bottom frame 1 are the same, which further facilitates the quick insertion of the first measuring block 23 and the second measuring block 24 between the first flap 34 and the second flap 35, thereby further improving the accuracy of the distance adjustment and ensuring the smoothness of the paper box folding process after the paper box folding mechanism is adjusted.

[0033] Please continue reading. Figure 1 , Figures 3 to 12 and Figure 15 In one embodiment, the folding guide bottom frame 1 is a sliding rail bottom frame, and the support structure 2 is slidably connected to the folding guide bottom frame 1. The size of the folding area A can be adjusted by adjusting the size of the quadrilateral area enclosed in the middle of the folding guide bottom frame 1 and the position of the support structure 2 on the folding guide bottom frame 1, thereby realizing the auxiliary folding of various sizes of airplane boxes.

[0034] Specifically, the guide frame 1 includes two parallel horizontal support rails 11 and two parallel vertical support rails 12. The two horizontal support rails 11 and the two vertical support rails 12 are located in the upper and lower planes respectively and are perpendicularly intersecting. A connecting plate 13 is provided at each intersection point of the horizontal support rails 11 and the vertical support rails 12. Each connecting plate 13 at its intersection point is slidably connected to the corresponding horizontal support rail 11 and the corresponding vertical support rail 12, and the position of the connecting plate 13 can be selectively fixed on the corresponding horizontal support rail 11 and the corresponding vertical support rail 12. With this configuration, the size of the quadrilateral formed by the horizontal support rails 11 and the vertical support rails 12 can be adjusted by adjusting the position of the four connecting plates 13 on the corresponding horizontal support rails 11 and the vertical support rails 12, thus constructing a two-dimensional sliding platform.

[0035] In one embodiment, the four connecting plates 13 include two first plates 131 and two second plates 132, with the first plates 131 and second plates 132 arranged opposite to each other. The two first plates 131 are respectively located above two different longitudinal support slide rails 12 and below one transverse support slide rail 11. The two second plates 132 are respectively located above two different longitudinal support slide rails 12 and below another transverse support slide rail 11.

[0036] In one embodiment, the transverse support slide rail 11 and the longitudinal support slide rail 12 are respectively connected to the first plate 131 and the second plate 132 by bolts.

[0037] It should be noted that when only the bolts between the transverse support slide rail 11 and the first plate 131 and the bolts between the transverse support slide rail 11 and the second plate 132 are loosened, while the bolts between the first plate 131 and the longitudinal support slide rail 12 and the bolts between the second plate 132 and the longitudinal support slide rail 12 remain locked, a first plate 131 and a second plate 132 fixed on the same longitudinal support slide rail 12 can slide synchronously along the transverse support slide rail 11, thereby adjusting the distance between the two longitudinal support slide rails 12. After adjustment, all the bolts between the transverse support slide rail 11 and the first plate 131 and the bolts between the transverse support slide rail 11 and the second plate 132 are tightened to form a stable folding guide bottom frame 1.

[0038] When only the bolts between the first plate 131 and the longitudinal support slide rail 12 are loosened, while the bolts between the second plate 132 and the longitudinal support slide rail 12, the bolts between the transverse support slide rail 11 and the first plate 131, and the bolts between the transverse support slide rail 11 and the second plate 132 remain locked, the two first plates 131 fixed on the same transverse support slide rail 11 can slide synchronously along the longitudinal support slide rail 11, thereby adjusting the distance between the two transverse slide rails 11. After adjustment, the bolts between the first plate 131 and the longitudinal support slide rail 12 are tightened to form a stable folding guide bottom frame 1.

[0039] When the bolts between the first plate 131 and the longitudinal support slide rail 12, the bolts between the transverse support slide rail 11 and the first plate 131, and the bolts between the transverse support slide rail 11 and the second plate 132 are loosened, while keeping the bolts between the second plate 132 and the longitudinal support slide rail 12 locked, the spacing between the two transverse support slide rails 11 and the two longitudinal support slide rails 12 can be adjusted as needed. After adjustment, all the bolts between the first plate 131 and the longitudinal support slide rail 12, the bolts between the transverse support slide rail 11 and the first plate 131, and the bolts between the transverse support slide rail 11 and the second plate 132 are tightened to form a stable guide frame 1.

[0040] As can be seen, the size of the folding area A of the folding guide frame 1 can be adjusted through the above three methods, thereby adapting to the folding of aircraft boxes with different sized base plates 31.

[0041] In one embodiment, a first support device 21 is fixedly mounted on a first plate 131 and can move synchronously with the first plate 131 when the size of the folding area A is adjusted. A second support device 22 is mounted on a second plate 132 and can move with the second plate 132 when the size of the folding area A is adjusted. The second support device 22 can slide relative to the second plate 132 so that after the folding area A of the folding guide frame 1 is adjusted and fixed, the relative positions of the first support device 21 and the second support device 22 are adjusted again, so that the distance D between the first reference surface 21a of the first support device 21 and the second reference surface 22a of the second support device 22 is adjusted to be the same as the distance W between the second flap 35 and the first flap 34 located on the same side.

[0042] Please continue reading. Figure 1 , Figures 3 to 12 and Figure 15 In one embodiment, the first support device 21 includes a first support rod 211 and a first folding guide wheel 212. The first support rod 211 is fixedly mounted on the first plate 131 to support the first flap 34, thereby assisting in folding the first flap 34. A first measuring block 23 is fixedly mounted on the side wall of the first support rod 211. The first folding guide wheel 212 is rotatably mounted on the first support rod 211. The annular surface of the first folding guide wheel 212 protrudes from the side wall of the first support rod 211 on the side where the folding area A is located, thereby providing rolling support for the cardboard 3. This not only facilitates the downward pressing of the cardboard 3 but also avoids scratching the cardboard 3, ensuring the folding efficiency of the airplane box while improving the yield of the airplane box.

[0043] Please see Figure 1 , Figures 3 to 11 and Figure 13 In one embodiment, the first support device 21 includes a first support rod 211, a first folding guide wheel 212, and a folding guide frame 213.

The second ranging block 24 is fixedly mounted on the second support rod 221. The locking member 222 is assembled with the longitudinal support slide rail 12, thereby locking or unlocking the second support rod 221 to the second plate 132.

[0045] Obviously, after the adjustment of folding area A is completed, both the first plate 131 and the second plate 132 are fixed to the folding guide frame 1 by bolts. At this time, by adjusting the relative position between the second support rod 221 and the second plate 132, the distance D between the first reference surface 21a of the first support device 21 and the second reference surface 22a of the second support device 22 is measured and adjusted, so that the paper box folding mechanism can adapt to the folding of cardboard 3 with the same size as the base plate 3 but different gaps 30. The paper box folding mechanism set in this way is not only convenient and quick to measure and adjust, but also highly adaptable and widely applicable.

[0046] In one embodiment, the second support device 22 further includes: a main slide rail 223, a telescopic slide rail 224, a stop block 225, and a support column 226.

A portion of the telescopic slide rail 224 extends beyond the end of the main slide track 2231 away from the first support device 21. A stop block 225 is installed on the main slide rail 223. The stop block 225 is connected to the telescopic slide rail 224 by fasteners, and the fasteners can lock or unlock the stop block 225 and the telescopic slide rail 224. A support column 226 is fixedly installed on the second plate 132. The end of the support column 226 away from the second plate 132 is slidably assembled with the portion of the telescopic slide rail 224 extending beyond the main slide track 2231.

[0048] In this embodiment, a groove 1320 is provided on the second plate 132. The second support rod 221 includes a locking part 2211, a support part 2212, and a guide mounting part 2213. The locking part 2211 is slidably connected to the second plate 132, and at least a portion of it overlaps with the groove 1320. A fastener passes through the locking part 2211 and the groove 1320 and connects to the longitudinal support slide rail 12, thereby locking or unlocking the second support rod 221 and the second plate 132. The support part 2212 connects the locking part 2211 and the guide mounting part 2213. An adjustment groove 2210 is provided on the guide mounting part 2213, and a limiting part 2232 protrudes from the outer wall of the main slide rail 223. The limiting part 2232 is adapted to the adjustment groove 2210, thereby limiting the adjustment range of the second support rod 221. The guide mounting part 2213 is connected to the main slide rail 223 by fasteners. When the second support rod 221 needs to be adjusted, the fasteners are released from the locking state between the guide mounting part 2213 and the main slide rail 223. After the second support rod 221 is adjusted, the guide mounting part 2213 and the main slide rail 223 are locked again by fasteners. It should be noted that the support part 2212 is perpendicular to the second plate 132, and the second ranging block 24 is mounted on the support part 2212 or the locking part 2211.

[0049] In one embodiment, a sliding engagement block 227 is also provided inside the longitudinal support slide rail 12. The locking member 222 passes through the locking part 2211 and the slide groove 1320 and is assembled with the sliding engagement block 227, thereby pressing and fixing the second support rod 221 onto the second plate 132, so that the second support rod 221, the second plate 132 and the longitudinal support slide rail 12 are locked and fixed together.

[0050] Please see Figure 1 , Figures 3 to 11 and Figure 14 In one embodiment, a first measuring block 23 is disposed on the first plate 131. A second measuring block 24 is disposed on the locking part 2211 of the second support rod 221.

The first measuring block 23 and the second measuring block 24 are disposed closer to the longitudinal support slide rail 12. When the longitudinal support slide rail 12 is used on the work platform, the cardboard 3 can be placed on the work platform and the distance between the first plate 131 and the second support rod 221 can be adjusted directly on the platform, thereby realizing the adjustment of the distance between the first support device 21 and the second support rod 221, making the adjustment operation more convenient and faster.

[0051] Please see Figure 3 , Figures 17 to 22In one embodiment, the carton folding mechanism further includes a counter 4, which is fixedly mounted on the connecting plate 13 by fastening screws to record the number of carton folds.

[0052] It should be noted that the function of counter 4 is to visually display how many paper boxes the folding device has folded within a certain period of time, thus automating the recording of the number of folded paper boxes. Counter 4 can be directly installed on the longitudinal support slide rail 12 or the transverse support slide rail 11, as long as it can record the number of paper boxes folded by the folding mechanism. Furthermore, the number of counters 4 is not limited to one; there can be one or more. Installing multiple counters 4 can improve the overall counting accuracy. For example, the average value of multiple counters 4 can be used as the actual count value to prevent errors in the counting result due to the malfunction of individual counters 4.

[0053] In one embodiment, the counter 4 includes: a housing 41, a housing end cap 42, a battery compartment 43, a rechargeable power supply 44, a photoelectric sensor 45, a display screen 46, a power supply connector 47, and a control switch 48.

[0054] Specifically, the housing 41 includes a mounting cavity 410 with an opening, a mounting port 411, and a counting detection window 412, wherein the counting detection window 412 faces the folding area A, so that the photoelectric sensor 45 installed in the mounting cavity 410 can accurately detect the number of folds through the counting detection window 412. The housing end cap 42 is detachably assembled with the housing 41, thereby closing the opening of the mounting cavity 410. A power supply port 420 is provided on the housing end cap 42. The battery compartment 43 is disposed in the mounting cavity 410, and its bottom is fixedly connected to the inner wall of the mounting cavity 410 by three fastening screws. The battery compartment 43 has a power mounting port 430, and the power mounting port 430 communicates with the power supply port 420. The housing end cap 42 is also fixedly connected to the battery compartment 43 by fastening screws, thereby improving the tightness and firmness of the connection between the power mounting port 430 and the power supply port 420. A rechargeable power supply 44 is detachably installed in the battery compartment 43 through the power supply port 420 and the power mounting port 430. The detection end of the photoelectric sensor 45 is aligned with the counting detection window 412, so that the photoelectric sensor 45 can count the number of folds of the paper box in the folding area A through the counting detection window 412.

[0055] The display screen 46 is installed inside the mounting port 411 and is electrically connected to the photoelectric sensor 45 to display the count of the photoelectric sensor 45 for user convenience. The power supply connector 47 is located inside the mounting cavity 410, between the battery compartment 43 and the inner wall of the outer casing 41. Both the photoelectric sensor 45 and the display screen 46 are electrically connected to the rechargeable power supply 44 via the power supply connector 47. The control switch 48 is installed on the end cover 42 of the outer casing and is electrically connected to the power supply connector 47. The control switch 48 controls the opening and closing of the counter 4.

[0056] Please continue reading. Figure 3 , Figures 17 to 22 In one embodiment, a snap-fit ​​groove 413 is provided on the side wall of the mounting cavity 410 near the opening. A snap-fit ​​block 421 is provided on the side wall of the outer casing end cover 42. The snap-fit ​​block 421 cooperates with the snap-fit ​​groove 413 to realize the detachable assembly between the outer casing end cover 42 and the outer casing 41. It should be noted that the connection method between the snap-fit ​​block 421 and the snap-fit ​​groove 413 facilitates fixing and disassembly. When it is necessary to perform internal operations on the counter 4 or replace parts, the outer casing end cover 42 can be easily removed from the outer casing. After the internal operations or parts replacement are completed, the outer casing end cover 42 can be installed on the outer casing 41.

[0057] In one embodiment, a limiting strip 414 is also provided on the side wall of the mounting cavity 410 near the opening. The limiting strip 414 protrudes from the side wall of the mounting cavity 410 and is located on the side of the snap-fit ​​groove 413 away from the housing end cap 42. The limiting strip 414 can prevent the housing end cap 42 from being completely embedded into the mounting cavity 410 due to excessive force during installation.

[0058] In one embodiment, the battery compartment 43 has a groove 431 on its end face near the outer casing end cover 42, which communicates with the power mounting port 430. The outer casing end cover 42 has a snap-fit ​​portion 422. When the outer casing end cover 42 is assembled with the outer casing 41, the power supply port 420 of the outer casing end cover 42 communicates with the power mounting port 430, and the snap-fit ​​portion 422 engages with the groove 431 to form a first snap-fit ​​structure. A snap-fit ​​spring 441 is provided on the outer side wall of the rechargeable power supply 44. When the rechargeable power supply 44 is installed into the battery compartment 43, the snap-fit ​​spring 441 engages with the first snap-fit ​​structure to achieve a detachable assembly between the rechargeable power supply 44 and the battery compartment 43, thereby facilitating the disassembly and replacement of the rechargeable power supply 44.

[0059] In one embodiment, a thickened portion 415 is further provided on the inner sidewall of the mounting cavity 410. A fixing screw hole is provided at the position corresponding to the thickened portion 415 on the outer sidewall of the housing 41, and the housing 41 is fixedly mounted on the connecting plate 13 by fastening screws. Due to the thickened portion 415, when the fastening screw passes through the fixing screw hole, the tip of the fastening screw can be embedded in the thickened portion 415, thereby preventing the sharp tip of the screw from being directly exposed inside the housing 41.

[0060] In one embodiment, a mounting groove 432 is provided on the bottom outer wall of the battery compartment 43, and the shape of the mounting groove 432 matches the shape of the power supply connector 47. A boss 416 extending towards the battery compartment 43 is provided on the side wall of the mounting cavity 410. When the battery compartment 43 is installed in the mounting cavity 410, the boss 416 abuts and fixes the power supply connector 47 in the mounting groove 432. The housing 41 configured in this way allows the power supply connector 47 to be installed more securely in the mounting groove 432, thereby preventing the power supply connector 47 from falling out of the mounting groove 432 due to vibration, loosening, or other reasons, and improving the overall structural stability of the counter 4.

[0061] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: 1) Utilizing the principle of vernier caliper measurement, the first measuring block 23 and the second measuring block 24 allow the carton folding mechanism to directly adjust the relative position between the first support device 21 and the second support device 22 based on the distance W between the first flap 34 and the second flap 35. This ensures that the distance D between the first reference surface 21a of the first support device 21 and the second reference surface 22a of the second support device 22 equals the distance W. This design avoids the cumbersome operation of measuring the distance W and then adjusting the distance D, improving the simplicity and speed of the adjustment mechanism.

[0062] 2) The function of counter 4 is to intuitively display how many airplane boxes the paper box folding device has folded within a certain period of time, so as to realize the function of automatically recording the number of airplane boxes folded.

[0063] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
