Description

Technical Field

[0001] The present application relates to the technical field of cardboard processing, and in particular to a paper folding machine and a compounding machine. Background Art

[0002] Before forming a paper box, the two pieces of cardboard need to be folded and glued separately, and then the two pieces of cardboard are composited. For the folding process of the cardboard, the cardboard is generally folded by an automated folding mechanism. Before folding the cardboard, the cardboard needs to be positioned first to ensure the accuracy of the folding position of the folding mechanism.

[0003] In the related art, manual positioning is generally used, but manual positioning has low production efficiency. Another method is positioning using a push gauge.

Moreover, the specific features, structures, materials, or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.

[0049] The paper folding machine 1000 according to the first embodiment of the present application includes: a transmission mechanism 100, a positioning mechanism 200, and a folding mechanism 300.

[0050] like Figure 1 As shown, the transport mechanism 100 is used to transport cardboard 700 .

[0051] For example, the transmission mechanism 100 is a belt transmission mechanism 100 , which transmits the cardboard 700 from the front work station to the positioning mechanism 200 via the belt.

[0052] like Figure 1 As shown, the positioning mechanism 200 is used to position the cardboard 700 on the transmission mechanism 100. Specifically, the positioning mechanism 200 is disposed beside the transmission mechanism 100. The positioning mechanism 200 includes a first driving component 210, a positioning plate 220, and at least one roller 230.

[0053] For example, Figure 1 As shown, in the embodiment of the present application, a plurality of rollers 230 are arranged along the conveying direction of the conveying mechanism 100. For example, in some other embodiments, a single roller 230 is provided, which is an elongated roller 230, with the axis of the roller 230 arranged along the conveying direction of the conveying mechanism 100. Specifically, the roller 230 is rubber-coated, which can enhance the friction between the roller 230 and the cardboard 700.

[0054] like Figure 1 As shown, the positioning plate 220 is arranged on one side of the transmission path of the transmission mechanism 100; the roller 230 is arranged above or below the transmission path of the transmission mechanism 100, and the roller 230 is used to drive the cardboard 700 on the transmission mechanism 100 to deviate toward the positioning plate 220, and make the cardboard 700 contact with the positioning plate 220 to position the cardboard 700; the first driving component 210 drives the connecting roller 230 to rotate the roller 230.

[0055] It can be understood that the transport path of the transport mechanism 100 is the moving path of the paperboard 700 .

[0056] For example, Figure 2 、 Figure 3 、 Figure 7 As shown, in an embodiment of the present application, the roller 230 is arranged below the transmission path of the transmission mechanism 100. When the transmission mechanism 100 transmits the cardboard 700 to the side of the positioning mechanism 200, the roller 230 is located below the cardboard 700 and contacts the cardboard 700, that is, the roller 230 supports the cardboard 700, and when the first driving component 210 drives the roller 230 to rotate, the roller 230 drives the cardboard 700 to deviate toward the positioning plate 220, so that the cardboard 700 contacts the positioning plate 220. The roller 230 plays the role of pulling the material, thereby achieving the purpose of positioning the cardboard 700.

[0057] For example, Figure 8 As shown, in some other embodiments, the roller 230 is arranged above the transmission path of the transmission mechanism 100. When the transmission mechanism 100 transmits the cardboard 700 to the side of the positioning mechanism 200, the roller 230 is located above the cardboard 700. Specifically, the transmission mechanism 100 is located below the cardboard 700. The roller 230 and the transmission mechanism 100 clamp the cardboard 700. At the same time, the roller 230 drives the cardboard 700 to deflect. Figure 8 In order to prevent the roller 230 from crushing the transmission mechanism 100, in other embodiments, such as Figure 9As shown, the positioning mechanism 200 further includes a support member 270, which is located below the paperboard 700. The support member 270 assists in supporting the paperboard 700 and clamps the paperboard 700 through the support member 270 and the roller 230. Figure 8 、 Figure 9 In the embodiment shown, in order to avoid a paper jam caused by a small gap between the roller 230 and the support member 270 or the transmission mechanism 100, another driving structure drives the connected roller 230 to move closer to or away from the support member 270 or the transmission mechanism 100. Specifically, before the cardboard 700 is transmitted to the side of the positioning mechanism 200, the roller 230 is driven away from the support member 270 or the transmission mechanism 100 to form a larger gap, which facilitates the transmission of the cardboard 700 to between the support member 270 / transmission mechanism 100 and the roller 230. Then, the roller 230 approaches the support member 270 / transmission mechanism 100 and presses on the upper surface of the cardboard 700, so that the roller 230 can simultaneously pull and press the material.

[0058] like Figure 1 、 Figure 3 、 Figure 4 As shown, the folding mechanism 300 is disposed on the other side of the transmission path of the transmission mechanism 100 and is used to fold the positioned cardboard 700 .

[0059] Specifically, the folding mechanism 300 is disposed on the other side of the transmission mechanism 100. It is understood that after one side of the paperboard 700 abuts against the positioning plate 220 to position the paperboard 700, the folding mechanism 300 folds the other side of the paperboard 700.

[0060] After the paperboard 700 is folded, the transport mechanism 100 continues to push the paperboard 700 toward the next workstation or the paper outlet 1001 of the paper folding machine 1000 .

[0061] It can be understood that the positioning mechanism 200 can automatically position the cardboard 700. In addition, the roller 230 only contacts the upper surface of the cardboard 700. The method of pulling the cardboard 700 to position by the roller 230 can avoid damaging the cardboard 700. The roller 230 occupies a small space, and the roller 230 does not need to move or only needs to move in a small range, so that positioning by the roller 230 is faster.

[0062] like Figure 1 As shown, the transmission mechanism 100 includes a first drive component 110, a transmission belt 120, and a push plate 130. The transmission belt 120 is used to carry the cardboard 700. The push plate 130 is set on the transmission belt 120. The first drive component 110 drives the transmission belt 120 to drive the push plate 130 to push the cardboard 700 along the transmission path.

[0063] Specifically, the conveyor belt 120 is connected end to end. The first drive assembly 110 drives the conveyor belt 120 in the conveying direction. The push plate 130 follows the movement of the conveyor belt 120 and is used to push the cardboard 700. It is understood that to improve transmission efficiency, the conveyor belt 120 rotates at a relatively high speed. Transporting the cardboard 700 solely through friction between the conveyor belt 120 and the cardboard 700 can easily cause slippage between the cardboard 700 and the conveyor belt 120, affecting the normal transmission of the cardboard 700. Propelling the cardboard 700 by the push plate 130 improves transmission stability and significantly increases transmission efficiency.

[0064] like Figure 1 As shown, the transmission mechanism 100 includes at least two groups.

[0065] It is understandable that the cardboard 700 includes a special-shaped cardboard 700 , that is, a special-shaped cardboard 700 whose one side is irregular, that is, non-straight.

[0066] The transmission mechanisms 100 are controlled independently of each other. When it is necessary to transmit the special-shaped cardboard 700, multiple independently arranged transmission mechanisms 100 are used to enable the push plates 130 of each transmission mechanism 100 to adjust their positions according to the side shape of the special-shaped cardboard 700 to ensure that each push plate 130 can contact the side of the cardboard 700 at the same time and push the cardboard 700 at the same time, avoiding the situation where only part of the push plates 130 are in contact with the cardboard 700, resulting in uneven force on the cardboard 700, large rotation, and affecting normal transmission.

[0067] Regarding the setting position of the roller 230, in the embodiment of the present application, as shown in FIG. Figure 2 、 Figure 3 、 Figure 7 As shown, the roller 230 is arranged below the transmission path of the transmission mechanism 100, and the positioning mechanism 200 also includes a pressing piece 250, a rocker 260, and a second driving component. The pressing piece 250 is arranged on the rocker 260, and the second driving component drives the rocker 260 to swing and drive the pressing piece 250 to press the cardboard 700 on the transmission mechanism 100.

[0068] When the conveying mechanism 100 conveys the cardboard 700 to the side of the positioning mechanism 200, the second driving component drives the swing arm 260 to swing, which drives the pressing piece 250 to press on the cardboard 700. The pressing piece 250 presses the cardboard 700. At the same time, the first driving component 210 drives the roller 230 to rotate, and the roller 230 pulls the cardboard 700. It can be understood that the cooperation of the pressing piece 250 can press the cardboard 700 while the roller 230 pulls the cardboard 700, thereby improving the stability of the roller 230 pulling the cardboard.

[0069] For example, Figure 2 、 Figure 3 As shown, in the embodiment of the present application, the first driving component 210 and the second driving component are the same motor 211, and the connection method between the motor 211 and the rocker arm 260 can be: the cam is set on the rotating shaft 212, the motor 211 is connected to the rocker arm 260 through the rotating shaft 212 and the cam 214, and the rocker arm 260 is driven to swing by the cam 214, or, in other embodiments, the motor 211 is directly connected to the rocker arm 260 through the rotating shaft 212. It can be understood that the transmission is more stable when the rocker arm 260 is connected through the cam 214.

[0070] Furthermore, in an embodiment of the present application, when the first drive component 210 and the second drive component are the same motor 211, the motor 211 is connected to the roller 230 in the following manner: the rotating shaft 212 is connected to the roller 230 via a plurality of synchronous belt assemblies 213. It should be noted that the synchronous belt assembly 213 includes a driving pulley, a driven pulley, and a transmission belt. It is understood that when only one motor 211 is used, the number of revolutions of the motor 211 required for the roller 230 and the swing arm 260 to perform corresponding actions is different. Specifically, in order to improve the material pulling effect of the roller 230, the roller 230 requires a higher rotation speed. The synchronous belt assembly 213 can increase the rotation speed of the roller 230 by the wheel difference between the driving pulley and the driven pulley of the synchronous belt assembly 213 without affecting the swing effect of the swing arm 260.

[0071] For another example, in some other embodiments, the first driving component 210 and the second driving component are two motors 211 , which respectively drive the connecting rocker 260 and the roller 230 .

[0072] The pressing member 250 includes a pressing plate or a pressing wheel.

[0073] like Figure 2 、 Figure 3 As shown, in the embodiment of the present application, the pressing member 250 includes a pressing wheel and is arranged corresponding to the roller 230.

[0074] It can be understood that by pressing the material through the pressing wheel, the influence of the pressing piece 250 on the material pulling of the roller 230 can be reduced while pressing the material. In addition, the pressing wheel and the roller 230 are arranged opposite to each other, and the cardboard 700 is clamped by the pressing wheel and the roller 230, which can ensure the smoothness of the rolling of the roller 230 and avoid the deformation of the cardboard 700 caused by the staggered arrangement of the pressing wheel and the roller 230.

[0075] In addition, an auxiliary plate 240 can be set below the transmission path to provide auxiliary support for the cardboard 700. The auxiliary plate 240 has a hole, and the roller 230 is set corresponding to the hole on the auxiliary plate 240 so that part of it passes through the auxiliary plate 240 to ensure that the roller 230 can contact the cardboard 700.

[0076] Regarding the location of the roller 230, in some other embodiments, such as Figure 8 As shown, the roller 230 is arranged above the transmission path of the transmission mechanism 100, and the positioning mechanism 200 also includes a rocker 260 and a second driving component. The roller 230 is arranged on the rocker 260, and the second driving component drives the rocker 260 so that the rocker 260 drives the roller 230 to approach the cardboard 700 on the transmission mechanism 100.

[0077] When the conveying mechanism 100 conveys the cardboard 700 to the side of the positioning mechanism 200, the second driving component drives the swing arm 260 to swing. The swing arm 260 drives the roller 230 to swing and press the roller 230 onto the cardboard 700. Specifically, the roller 230 presses on the cardboard 700. Then, the first driving component 210 drives the roller 230 to deflect the cardboard 700. It can be understood that the roller 230 simultaneously pulls the cardboard and cooperates with the support member 270 to press the cardboard.

[0078] Regarding the above Figure 8 In some other embodiments shown in FIG. 1 , in order to prevent the roller 230 from crushing the transmission mechanism 100, or when the transmission mechanism 100 is a belt-type transmission mechanism, to prevent the belt and the roller 230 from being unable to press the cardboard 700 well, as shown in FIG. Figure 9 As shown, in some other embodiments, the positioning mechanism 200 further includes a support member 270, which assists in supporting the cardboard 700. When the transmission mechanism 100 transmits the cardboard 700 to the side of the positioning mechanism 200, the support member 270 carries part of the cardboard 700, and the rocker 260 drives the roller 230 to swing and press the roller 230 above the cardboard 700 supported by the support member 270.

[0079] In addition, the first driving component 210 and the second driving component can be the same motor 211, and the swing rod 260 can be driven to swing and the roller 230 can be driven to rotate by the motor 211. Alternatively, two motors 211 can be used, and the two motors 211 can be driven separately.

[0080] Furthermore, the support member 270 is a support plate.

[0081] like Figure 4 、 Figure 5 、 Figure 6 As shown, the folding mechanism 300 includes a paper aligning knife 310, a second driving assembly 320, a fixed plate 330 and a folding assembly 340. The paper aligning knife 310 and the fixed plate 330 are relatively arranged on the upper and lower sides of the transmission path of the transmission mechanism 100. The folding assembly 340 is used to fold part of the cardboard 700 toward one side of the paper aligning knife 310; the second driving assembly 320 drives the paper aligning knife 310 to adjust the relative position of the paper aligning knife 310 and the cardboard 700.

[0082] It is understood that when the cardboard 700 is transferred to the side of the positioning mechanism 200, the other side of the cardboard 700 will be located next to the folding mechanism 300. When the cardboard 700 is positioned, the folding mechanism 300 will fold the other side of the cardboard 700. Specifically, the other side of the cardboard 700 will be located between the fixed plate 330 and the paper jogging knife 310. When the cardboard 700 is positioned, the folding line of the cardboard 700 will align with the edge of the fixed plate 330. The second driving assembly 320 drives the edge of the paper jogging knife 310 to align with the folding line of the cardboard 700. It is understood that the edge of the paper jogging knife 310 is in the shape of a blade. Then, the folding assembly 340 folds the portion of the cardboard 700 that protrudes from the edges of the fixed plate 330 and the paper jogging knife 310, specifically, folding it toward one side of the paper jogging knife 310.

[0083] In the embodiments of the present application, Figure 5 、 Figure 10 As shown, when the paper aligning knife 310 is set on the upper side of the transmission path, the fixing plate 330 is set on the lower side of the transmission path, and the folding component 340 folds the cardboard 700 so that part of the cardboard 700 is folded upward and part of the cardboard 700 is folded to the upper side of the paper aligning knife 310.

[0084] In order to obtain paperboard 700 with different folding directions, in some other embodiments, such as Figure 6 、 Figure 11 As shown, when the paper aligning knife 310 is set on the lower side of the transmission path, the fixing plate 330 is set on the upper side of the transmission path, and the folding component 340 folds the cardboard 700, so that the cardboard 700 is partially folded downward and partially folded to the lower side of the paper aligning knife 310.

[0085] After the cardboard 700 is folded, the second drive assembly 320 drives the paper aligning knife 310 to move horizontally to move away from the folded portion of the cardboard 700. Then, the push plate 130 of the transmission mechanism 100 pushes the cardboard 700 away from the folding mechanism 300 and transmits it to the next station.

[0086] like Figure 4 、 Figure 5 、 Figure 6 As shown, the folding assembly 340 includes a folding plate 341 and a third driving assembly 342 . The third driving assembly 342 drives the folding plate 341 to flip the folding plate 341 toward the direction close to the paper jogging knife 310 .

[0087] Specifically, after the paperboard 700 is positioned, the portion of the paperboard 700 protruding from the edge of the fixing plate 330 and the paper aligning knife 310 is located on the turning path of the folding plate 341. Figure 10 、 Figure 11The arc with an arrow is the flipping path of the folding plate 341. The third driving assembly 342 drives the folding plate 341 to flip. Since the cardboard 700 is located between the fixing plate 330 and the paper aligning knife 310, it can fix the cardboard 700. The folding plate 341 drives the cardboard 700 to fold, and can accurately fold the part of the cardboard 700 protruding from the above-mentioned edge. Specifically, the folding plate 341 can fold the cardboard 700 onto one side of the paper aligning knife 310. The folding plate 341 and the paper aligning knife 310 together clamp the folded part of the cardboard 700 to improve the folding effect.

[0088] like Figure 1 、 Figure 2 As shown, the paper folding machine 1000 further includes a glue dispensing mechanism 400 , which is disposed on one side of the transmission path of the transmission mechanism 100 and is used to dispense glue to the folded paperboard 700 .

[0089] In an embodiment of the present application, the glue dispensing mechanism 400 and the positioning mechanism 200 are arranged on the same side of the transmission mechanism 100, and glue is dispensed on the folded side of the cardboard 700 so that the folded part of one cardboard is bonded to the folded part of the other cardboard to compound the two cardboards 700.

[0090] In some other embodiments, the glue dispensing mechanism 400 may also be arranged on the same side as the folding mechanism 300 to dispense glue on the folded side of the paperboard 700 .

[0091] like Figure 1 As shown, the paper folding machine 1000 also includes a frame 510 and a guide rail 520; the guide rail 520 is mounted on the frame 510, and the transmission mechanism 100, the positioning mechanism 200, and the folding mechanism 300 are all arranged on the guide rail 520, so that the transmission mechanism 100, the positioning mechanism 200, and the folding mechanism 300 can move horizontally along the guide rail 520 respectively.

[0092] It can be understood that the guide rail 520 is arranged along the width direction of the paper folding machine 1000 and is perpendicular to the transmission direction of the transmission mechanism 100. The transmission mechanism 100, the positioning mechanism 200, and the folding mechanism 300 can be moved in the horizontal direction through the guide rail 520 to adjust the distance between each mechanism to adapt to cardboards 700 of different sizes and shapes.

[0093] In addition, it can be understood that the transmission mechanism 100 includes multiple ones, and the horizontal distance between each transmission mechanism 100 can be adjusted by the guide rail 520 to better adapt to the special-shaped cardboard 700.

[0094] like Figure 1 、 Figure 2 、 Figure 4As shown, in the embodiment of the present application, the paper folding machine 1000 further includes a speed limiting mechanism 600, which is disposed between the folding mechanism 300 and the conveying mechanism 100, and / or between the positioning plate 220 and the conveying mechanism 100, for limiting the conveying speed of the paperboard 700. It is understood that to prevent the paperboard 700 from being conveyed too quickly and missing the positioning mechanism 200 and the folding mechanism 300, the speed limiting mechanism 600 limits the speed of the paperboard 700, thereby ensuring that the paperboard 700 can be conveyed to the correct position via the conveying mechanism 100.

[0095] In one embodiment, the speed limiting mechanism 600 includes a ball bearing 610, a base plate 620, and a mounting plate 630. The base plate 620 is disposed below the transmission path and along the transmission direction. The mounting plate 630 is disposed above the transmission path and opposite the base plate 620. The ball bearings 610 are disposed within mounting holes in the mounting plate 630. A plurality of ball bearings 610 are arranged along the length of the mounting plate 630, with the lower ends of the ball bearings 610 protruding from the mounting plate 630. When a cardboard 700 is transmitted to the speed limiting mechanism 600, the ball bearings 610 cooperate with the base plate 620 to press against the cardboard 700, thereby hindering its forward movement and slowing its speed. Under the rolling action of the ball bearings 610, the cardboard 700 can continue to move forward. It can be understood that the speed limiting mechanism 600 can prevent the cardboard 700 from moving forward without the transmission action of the transmission mechanism 100, thereby preventing it from missing the folding mechanism 300 and the positioning mechanism 200 due to its own inertia, making the transmission position of the transmission mechanism 100 more accurate. In addition, the paper folding machine 1000 is set at an angle to prevent the cardboard 700 from sliding over the positioning mechanism 200 and the folding mechanism 300 when it is transmitted along the inclined direction.

[0096] In addition, in another embodiment, specifically, when there is a structure for auxiliary support below the speed limiting mechanism 600, the speed limiting mechanism 600 may only include the mounting plate 630 and the ball 610, for example, Figure 2 、 Figure 3 As shown, the auxiliary plate 240 is provided to support the paperboard 700 , that is, there is no need to additionally provide the bottom plate 620 , or in other words, the auxiliary plate 240 is equivalent to the bottom plate 620 .

[0097] like Figure 12 As shown, the compound machine according to the second embodiment of the present application includes: two paper folding machines 1000 of the first embodiment, one of the paper folding machines 1000 is arranged above the other paper folding machine 1000, at least one paper folding machine 1000 is arranged at an angle, and the paper output ends 1001 of the two paper folding machines 1000 are close to each other so that the cardboards 700 output by the two paper folding machines 1000 are compounded with each other.

[0098] Specifically, the folding mechanism 300 of the paper folding machine 1000 disposed above folds one side of the paperboard 700 downward, as shown in FIG. Figure 6 In addition, the folding mechanism 300 of the paper folding machine 1000 is placed below to fold the other side of the cardboard 700 upward, as shown Figure 5 The folding mechanism shown.

[0099] In addition, before the paper folding machine 1000 outputs the cardboard 700, the cardboard 700 is glued manually or by the glue dispensing mechanism 400. It can be understood that the paper output ends 1001 of the two paper folding machines 1000 are close to each other. When the two paper folding machines 1000 output the cardboard 700 at the same time, the two cardboards 700 will be compounded with each other. Subsequently, they can be pressed together again manually or by machine to complete the compounding of the two cardboards 700.

[0100] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features of the embodiments can be combined with each other unless there is a conflict.
