[0023] Please refer to Figure 1 , this embodiment provides a box supporting device 100, which includes a first lifting assembly 110, a second lifting assembly 120, a box pressing plate 130, and a plurality of box supporting assemblies 140; the first lifting assembly 110 and the second lifting assembly 120 are arranged at intervals relatively; the first lifting assembly 110 includes a driving motor 111; the second lifting assembly 120 includes a supporting cylinder 121; the box pressing plate 130 has a rectangular frame structure, and its opposite sides are respectively connected to the output end of the driving motor 111 and the output end of the supporting cylinder 121; the plurality of box supporting assemblies 140 are respectively arranged around the box pressing plate 130, and the box supporting assembly 140 includes a box supporting member 141 and a guiding driving member 142 which are drivingly connected, at least part of the guiding driving member 142 is arranged on the box pressing plate 130, and the guiding driving member 142 can drive the box supporting member 141 to approach or move away from the axis of the box pressing plate 130; the first lifting assembly 110 and the second lifting assembly 120 can drive the box pressing plate 130 and the box supporting assemblies 140 to move in the vertical direction.

[0024] Specifically, as Figure 1 shown, the box supporting device 100 includes a first lifting assembly 110 and a second lifting assembly 120 which are arranged at intervals relatively. A preset interval for placing the box body is arranged between the first lifting assembly 110 and the second lifting assembly 120. When the box body moves between the first lifting assembly 110 and the second lifting assembly 120, the first lifting assembly 110 and the second lifting assembly 120 can drive the box pressing plate 130 and the box supporting assemblies 140 to move in the vertical direction to adapt to the height of the box body.

[0025] As Figure 1 shown, the first lifting assembly 110 includes a driving motor 111, and the driving motor 111 can provide upward or downward driving force for the whole device. Among them, the driving motor 111 can select different types according to actual needs, such as a servo motor, so as to realize precise lifting control. Compared with the prior art in which both sides use cylinders to control the up and down movement, the setting of the servo motor can accurately control the acceleration and deceleration, and it is more convenient for adjusting the height of the box pressing plate 130.

[0026] As Figure 4As shown, the second lifting assembly 120 includes a support cylinder 121. The support cylinder 121 uses compressed air as the power source and has the advantages of simple structure, rapid action, and convenient maintenance. During operation, by controlling the intake and exhaust volumes of the compressed air, the telescopic length of the output end of the support cylinder 121 can be adjusted, thereby realizing a lifting action in coordination with the first lifting assembly 110 and ensuring the stability and balance of the pressing box plate 130 during the lifting process. Moreover, the setting of the support cylinder 121 can also provide a good supporting effect on the pressing box plate 130, making the height adjustment process of the box support device 100 more stable and reliable.

[0027] The pressing box plate 130 has a rectangular frame structure, and its middle part has a rectangular hollow structure. Both sides of the pressing box plate 130 are respectively connected to the driving motor 111 and the support cylinder 121. This connection method enables the first lifting assembly 110 and the second lifting assembly 120 to synchronously drive the pressing box plate 130 to move in the vertical direction. For example, when the driving motor 111 rotates to output power, the power is transmitted to one side of the pressing box plate 130 through the connecting component, and at the same time, the support cylinder 121 cooperates with telescoping, providing support and power assistance on the other side to ensure the stable lifting of the pressing box plate 130.

[0028] As Figure 1 shown, a plurality of box support assemblies 140 are distributed around the pressing box plate 130 and can perform the action of expanding the box from multiple directions. The box support member 141 is in direct contact with the box body and serves to expand the box opening of the box body. Its shape and material can be designed according to different box types. For example, for boxes containing fragile items, the box support member 141 can be made of soft rubber material to avoid damaging the box body. Preferably, the box support member 141 has a certain inclination angle to better push the box body away by a certain angle.

[0029] The guiding drive member 142, as the core drive part of the box support assembly 140, is at least partially installed on the pressing box plate 130. It converts the power into a linear motion of the box support member 141 through the internal transmission structure, thereby realizing the action of the box support member 141 moving closer to or farther from the axis of the pressing box plate 130. When it is necessary to lift the box body, the guiding drive member 142 drives the box support member 141 to move in a direction away from the axis of the pressing box plate 130, so that it contacts the inner wall of the box body and applies a supporting force; after the operation is completed, the guiding drive member 142 drives the box support member 141 to move in a direction closer to the axis of the pressing box plate 130 to facilitate the withdrawal of the device and the next operation.

[0030] It should be noted that, first, in an implementable manner of the present application, the second lifting assembly 120 further includes a quick exhaust valve connected to the support cylinder 121. When the second lifting assembly 120 needs to descend, the compressed air originally in the cavity of the support cylinder 121 needs to be quickly exhausted to enable the cylinder to quickly retract and drive the pressing box plate 130 and the box supporting assembly 140 to descend. Traditional exhaust methods may result in a slow exhaust speed due to factors such as a long exhaust path and large exhaust resistance, thus affecting the working efficiency of the device. The setting of the quick exhaust valve can quickly exhaust the compressed air, greatly shortening the retraction time of the support cylinder 121, and thus improving the lifting efficiency of the box supporting device 100.

[0031] In addition, the presence of the quick exhaust valve can also enhance the stability of the device operation. During the rapid exhaust process of the support cylinder 121, the quick exhaust valve can ensure the smoothness of the exhaust process, avoiding phenomena such as jitter and jamming when the cylinder retracts due to poor exhaust. This is crucial for ensuring that the pressing box plate 130 and the box supporting assembly 140 can descend smoothly and accurately to the predetermined position during the descent process, helping to improve the accuracy and reliability of the box supporting device 100 in operating on the box body and preventing damage to the box body due to device instability.

[0032] Second, in an implementable manner of the present application, the drive motor 111 is a servo motor, and the first lifting assembly 110 further includes an electric cylinder 115 connected to the servo motor. The servo motor is used to provide rotational power, and the setting of the electric cylinder 115 can convert the rotational motion into a linear motion; a push rod is also provided at the end of the electric cylinder 115 away from the servo motor (i.e., the output end), and the end of the push rod can be connected to the pressing box plate 130. The electric cylinder 115 can drive the push rod to move in the vertical direction through the conversion of linear motion, so as to drive the pressing box plate 130 to move up and down in the vertical direction through the push rod.

[0033] Of course, in addition to the electric cylinder 115, other electric actuators such as a ball screw module can also be used, as long as it can convert the rotational motion of the servo motor into a linear motion, and the present application does not impose any restrictions on this.

[0034] Third, as Figure 2As shown in the figure, in an implementable embodiment of the present application, the pressing box plate 130 includes a stacked aluminum pressing plate 131 and a polyurethane plate 132. The polyurethane plate 132 is disposed on the side of the aluminum pressing plate 131 away from the first lifting assembly 110 and the second lifting assembly 120. The aluminum pressing plate 131 is characterized by light weight and high strength, enabling it to effectively reduce the weight of the entire box supporting device 100 while having a certain load-bearing capacity, reducing the load pressure on the first lifting assembly 110 and the second lifting assembly 120, and improving the flexibility and efficiency of the device operation. In addition, the aluminum plate has good corrosion resistance and is not prone to rust in complex environments such as humidity, acid, and alkali, ensuring the long-term stable operation of the pressing box plate 130, reducing maintenance costs and replacement frequencies. The polyurethane plate 132 can increase friction and has good electrical conductivity, preventing problems such as box internal adhesion caused by static electricity.

[0035] Fourth, in an implementable embodiment of the present application, the guiding and driving member 142 is a guide rod cylinder, and the box supporting member 141 is connected to the output end of the guide rod cylinder. The guide rod cylinder includes a cylinder body and a guide rod. There is a piston and a piston rod in the cylinder body, and the piston is driven to move linearly by compressed air; the guide rod is arranged parallel to the piston rod to provide precise guidance for the piston rod.

[0036] When compressed air enters the rodless cavity of the cylinder body, it pushes the piston to drive the piston rod to extend, and at the same time the guide rod moves synchronously with the piston rod; conversely, when compressed air enters the rod cavity, the piston rod retracts. The presence of the guide rod effectively prevents the bending and torsion of the piston rod, improving the stability of the output force and the motion accuracy.

[0037] The box support device 100 provided by the present application includes a first lifting assembly 110, a second lifting assembly 120, a box pressing plate 130, and a plurality of box support assemblies 140; the first lifting assembly 110 and the second lifting assembly 120 are arranged at intervals relative to each other, the first lifting assembly 110 includes a driving motor 111; the second lifting assembly 120 includes a support cylinder 121; the box pressing plate 130 has a rectangular frame structure, and its opposite sides are respectively connected to the output end of the driving motor 111 and the output end of the support cylinder 121; the plurality of box support assemblies 140 are respectively arranged around the box pressing plate 130, and the box support assembly 140 includes a box support member 141 and a guiding driving member 142 which are drivingly connected, at least a part of the guiding driving member 142 is arranged on the box pressing plate 130, and the guiding driving member 142 can drive the box support member 141 to approach or move away from the axis of the box pressing plate 130; the first lifting assembly 110 and the second lifting assembly 120 can drive the box pressing plate 130 and the box support assemblies 140 to move in the vertical direction. Through the arrangement of the first lifting assembly 110 and the second lifting assembly 120, the height of the box pressing plate 130 can be flexibly adjusted to adapt to cartons of different heights; and the driving motor 111 of the first lifting assembly 110 provides power, which can accurately control acceleration and deceleration, improving the overall stability of the mechanism. The support cylinder 121 of the second lifting assembly 120 can further support the box pressing plate 130, thereby improving the stability and reliability of the box support device 100. The above box support device 100 has strong applicability, can be adapted to cartons of various specifications, and has strong stability and reliability.

[0038] Exemplarily, as Figure 2 and Figure 4 shown, the first lifting assembly 110 further includes a first mounting bracket 112, the first mounting bracket 112 includes a first support frame 1121 and a first limiting surface 1122, and the first limiting surface 1122 covers one side of the first support frame 1121; the driving motor 111 is arranged vertically in the first support frame 1121, and the output end of the driving motor 111 passes through the first support frame 1121 to be connected to the box pressing plate 130; the second lifting assembly 120 further includes a second mounting bracket 122, the second mounting bracket 122 includes a second support frame 1221 and a second limiting surface 1222, and the second limiting surface 1222 covers one side of the second support frame 1221; the support cylinder 121 is arranged vertically in the second support frame 1221, and the output end of the support cylinder 121 passes through the second support frame 1221 to be connected to the box pressing plate 130.

[0039] Specifically, the first support frame 1121 is preferably formed by welding or bolt - connecting metal profiles to form a rigid frame structure. Its main function is to provide mechanical support for the driving motor 111, bear the vibration and torque generated during motor operation, and prevent the motor from displacement or damage due to uneven force. The internal space of the frame is designed according to the external dimensions of the driving motor 111 to ensure that the motor can be stably installed.

[0040] As Figure 4 shown, the first limiting surface 1122 is preferably a flat metal plate, which is fixed to one side of the support frame by welding or bolts. Its function is to serve as a positioning reference for motor installation to ensure accurate vertical installation of the motor; and it can limit the lateral displacement of the motor during operation, enhancing stability. In addition, the first limiting surface 1122 and the second limiting surface 1222 are arranged at a relative interval, which can further limit the box body, prevent the box body from moving left and right, and improve the stability and reliability of the box - supporting process.

[0041] The driving motor 111 is arranged vertically so that the axis of its output shaft is consistent with the lifting direction of the pressing plate 130. The output end of the driving motor 111 passes through the reserved hole position on the support frame and is rigidly connected to one side of the pressing plate 130, thereby playing a certain guiding and limiting effect on the displacement direction of the pressing plate 130, ensuring that the output end of the driving motor 111 always moves vertically in a telescopic manner.

[0042] Similarly, as Figure 2 shown, the structure of the second support frame 1221 is the same as that of the first support frame 1121, and its size is adapted to the external dimensions and installation requirements of the support cylinder 121 to accommodate the support cylinder 121. The function of the second limiting surface 1222 is the same as that of the first limiting surface 1122, which is used for positioning and limiting the lateral displacement of the support cylinder 121.

[0043] The support cylinder 121 is arranged vertically so that the telescopic direction of its piston rod is consistent with the lifting direction of the pressing plate 130, ensuring that the cylinder can stably provide a supporting force. The output end of the support cylinder 121 passes through the guiding hole on the support frame and is connected to the other side of the pressing plate 130, thereby playing a certain guiding and limiting effect on the displacement direction of the pressing plate 130, ensuring that the output end of the support cylinder 121 always moves vertically in a telescopic manner. Preferably, to reduce friction and wear during movement, a linear bearing or wear - resistant bushing is installed in the guiding hole.

[0044] Optionally, as Figure 2As shown, the first lifting assembly 110 further includes a first guide rod 113. The first guide rod 113 is on the same horizontal plane as the drive motor 111 and is arranged at intervals. At least a part of the first guide rod 113 is disposed within the first mounting bracket 112 and passes through the first support frame 1121 to be connected to the pressing box plate 130; As Figure 4 shown, the second lifting assembly 120 further includes a second guide rod 123. The second guide rod 123 is on the same horizontal plane as the support cylinder 121 and is arranged at intervals. At least a part of the second guide rod 123 is disposed within the second mounting bracket 122 and passes through the second support frame 1221 to be connected to the pressing box plate 130.

[0045] Specifically, as Figure 2 shown, the first guide rod 113 and the output shaft of the drive motor 111 are at the same horizontal height, ensuring the synchronization of their movements in the vertical direction. In a specific embodiment of the present application, the number of the first guide rods 113 is two, and the two first guide rods 113 are respectively located on opposite sides of the drive motor 111. When the drive motor 111 drives the pressing box plate 130 to rise through the electric cylinder 115, the guide rods can provide support synchronously to prevent the pressing box plate 130 from tilting due to uneven force.

[0046] Similarly, as Figure 4 shown, the second guide rod 123 and the output shaft of the support cylinder 121 are at the same horizontal height, ensuring the synchronization of their movements in the vertical direction. In a specific embodiment of the present application, the number of the second guide rods 123 is two, and the two second guide rods 123 are respectively located on opposite sides of the support cylinder 121. When the support cylinder 121 drives the pressing box plate 130 to rise, the guide rods can provide support synchronously to prevent the pressing box plate 130 from tilting due to uneven force.

[0047] Through the arrangement of the first guide rod 113 and the second guide rod 123, the up and down movement process of the pressing box plate 130 becomes more stable and reliable.

[0048] In an implementable embodiment of the present application, as Figure 3As shown, the first lifting assembly 110 further includes a first mounting plate 114. The first mounting plate 114 includes a first support plate 1141 and a first connecting plate 1142. The first connecting plate 1142 is connected to the output end of the driving motor 111; the first connecting plate 1142 is perpendicularly arranged with respect to the first support plate 1141, and one end of the first connecting plate 1142 away from the first support plate 1141 is used for connecting with the pressing box plate 130; the second lifting assembly 120 further includes a second mounting plate 124. The second mounting plate 124 includes a second support plate 1241 and a second connecting plate 1242. The second connecting plate 1242 is connected to the output end of the supporting cylinder 121; the second connecting plate 1242 is perpendicularly arranged with respect to the second support plate 1241, and one end of the second connecting plate 1242 away from the second support plate 1241 is used for connecting with the pressing box plate 130.

[0049] Specifically, as Figure 3 shown, the first support plate 1141 is preferably a rectangular metal plate, which is horizontally arranged on the top of the first support frame 1121 and is spaced from the first support frame 1121. The number of the first connecting plates 1142 includes a plurality, and the plurality of first connecting plates 1142 are spaced and perpendicularly arranged with respect to the plate length direction of the first support plate 1141, and are used for connecting with the pressing box plate 130.

[0050] Similarly, as Figure 3 shown, the second support plate 1241 is preferably a rectangular metal plate, which is horizontally arranged on the top of the second support frame 1221 and is spaced from the second support frame 1221. The number of the second connecting plates 1242 includes a plurality, and the plurality of second connecting plates 1242 are spaced and perpendicularly arranged with respect to the plate length direction of the second support plate 1241, and are used for connecting with the pressing box plate 130.

[0051] It should be noted that during the lifting process, the first mounting plate 114 and the second mounting plate 124 need to act synchronously to ensure the stable lifting of the pressing box plate 130. For example, when the driving motor 111 drives the pressing box plate 130 to rise, the supporting cylinder 121 needs to extend synchronously to provide auxiliary support. At this time, the rigid structures of the two mounting plates can ensure the consistency of the actions and avoid jamming or shaking caused by delay or non-synchronization.

[0052] Through the settings of the first mounting plate 114 and the second mounting plate 124, the driving motor 111 and the supporting cylinder 121 can be respectively connected to jointly support the weight and working load of the pressing box plate 130. The symmetrical layout of the first mounting plate 114 and the second mounting plate 124 ensures the uniform distribution of the load.

[0053] Exemplarily, the plate length of the first connecting plate 1142 is less than that of the second connecting plate 1242; the first connecting plate 1142 has a first U-shaped groove opened along the plate thickness direction, and the pressing box plate 130 is provided with a plurality of first adjusting holes corresponding to the first U-shaped groove, and the plurality of first adjusting holes are arranged at intervals along the plate length direction of the first connecting plate 1142; the second connecting plate 1242 has a second U-shaped groove opened along the plate thickness direction, and the pressing box plate 130 is provided with a plurality of second adjusting holes corresponding to the second U-shaped groove, and the plurality of second adjusting holes are arranged at intervals along the plate length direction of the second connecting plate 1242.

[0054] Specifically, the setting of the first connecting plate 1142 can transmit precise lifting power, and the shorter plate length can reduce elastic deformation and improve the motion transmission accuracy; while the setting of the second connecting plate 1242 connects the support cylinder 121 and the pressing box plate 130, mainly providing support force, and the longer plate length can increase the support moment and improve the anti-overturning ability.

[0055] Among them, a U-shaped groove is opened on the first connecting plate 1142. The U-shaped groove allows the connecting plate to slide along the notch direction before bolt fastening, providing a fine-tuning space for installation. Correspondingly, a plurality of adjusting holes are arranged at intervals along the plate length direction to form multiple positioning points.

[0056] Similarly, a U-shaped groove is opened on the second connecting plate 1242. The U-shaped groove allows the connecting plate to slide along the notch direction before bolt fastening, providing a fine-tuning space for installation. Correspondingly, a plurality of adjusting holes are arranged at intervals along the plate length direction to form multiple positioning points.

[0057] By sequentially passing the fixing parts through the U-shaped groove and the adjusting holes, the first connecting plate 1142 or the second connecting plate 1242 can be fixedly connected to the pressing box plate 130. By selecting different adjusting holes to align with the U-shaped groove, the position of the pressing box plate 130 and the box support assembly 140 can be adjusted, so as to adapt to boxes of different sizes, further improving the use flexibility and reliability of the box support device 100.

[0058] In an implementable manner of the present application, as Figure 3 shown, the box support assembly 140 further includes a plurality of bellows mounting plates 143 and a bellows 144. The plurality of bellows mounting plates 143 are sequentially arranged around the guiding and driving member 142 and are connected to each other; the bellows 144 is sleeved on the outer wall of the bellows mounting plate 143.

[0059] Specifically, the bellows mounting plate 143 is preferably made of a lightweight and strong enough material, such as an aluminum alloy plate or a stainless steel plate. The plurality of bellows mounting plates 143 enclose to form a protective cover sleeved outside the guiding and driving member 142, which can not only provide an installation reference surface for the bellows 144 to ensure its stable fixation, but also block larger particulate dust from directly contacting the guiding and driving member 142, improving the service life of the box support assembly 140.

[0060] The bellows cover 144 is preferably supported by high-density nylon fabric or PVC-coated material, with a smooth surface and tight sealing, which can effectively isolate dust particles and liquid penetration; at the same time, since the bellows cover 144 has multiple folding structures, when it is collided, the impact force is dispersed through the compression deformation of the folds, reducing the damage to the internal components, further improving the protection effect on the guiding driving member 142, and improving the use reliability of the box support device 100.

[0061] The above are only optional embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

[0062] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present invention will not separately describe various possible combination methods.
