Description

Technical Field

[0001] This utility model relates to the field of automatic packaging technology, and in particular to a box position correction device and a corner sealing equipment. Background Technology

[0002] A carton sealing machine is a commonly used packaging machine that uses sealing tape to seal cartons. It is economical and fast, completing the top and bottom sealing operations in one pass. Carton sealing machines offer fast packaging speed, high efficiency, and aesthetically pleasing packaging, and are widely used in the manufacturing industries of home appliances, electronics, food, dairy products, oils, cosmetics, beverages, and electrical appliances.

[0003] During the cardboard box packing process, tape is usually applied first to the center of the bottom and top of the box, followed by tape to the four corners. However, after applying tape to the center seam at the top and bottom of the box, the folded edges on both sides of the box opening, under their own stress, cause the center seam to bulge outwards. For boxes with a large length-to-width ratio, this bulge at the bottom can cause the box to tilt freely to both sides when placed. Consequently, when the tilted box is conveyed to the corner sealing machine for corner tape application, problems such as tape misalignment and uneven tape application can easily occur, severely affecting the sealing effect.

[0004] Therefore, there is an urgent need for a container position correction device and a corner sealing device to solve the above-mentioned technical problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a box position correction device and a corner sealing equipment, which can automatically correct the position of the box before applying adhesive, thereby improving the sealing effect of the box.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] On the one hand, this utility model provides a box position correction device, including:

[0008] A connecting mechanism is configured to be located at the outlet of a first conveying mechanism, which is used to convey a box along a first direction. The connecting mechanism includes a first driving assembly and two clamping assemblies arranged opposite each other along a second direction. The first driving assembly is used to drive the two clamping assemblies to move along the second direction to clamp the box from both sides. The clamping assemblies include a second conveying mechanism. When the box is in the clamped state, the two sets of second conveying mechanisms are used to drive the box forward or backward along the first direction.

[0009] A baffle mechanism is configured to be located below the first conveying mechanism and upstream of the connecting mechanism. The baffle mechanism includes a second driving component and a baffle. The second driving component is used to drive the baffle to move in a third direction to extend above the first conveying mechanism. When the two sets of the second conveying mechanisms drive the box to retreat to the baffle mechanism, the baffle abuts against the box to correct the position of the box.

[0010] In some possible implementations, the first conveying mechanism includes a first frame and a plurality of rollers rotatably mounted on the first frame, the rollers extending along the second direction;

[0011] The clamping assembly further includes a movable seat, which is movably disposed on the first frame along the second direction and movably passes through a portion of the roller. The first drive assembly is fixed to the first frame and drivenly connected to the movable seat.

[0012] The second conveying mechanism is disposed on the movable seat. The second conveying mechanism includes a first conveyor belt extending along the first direction. The conveying surface of the first conveyor belt can be attached to the side of the box body for clamping the box body and driving the box body to move along the first direction.

[0013] In some possible implementations, the first drive assembly includes a motor fixed to the first frame and a bidirectional lead screw connected to the motor. Nut blocks are screwed onto the two threaded rods of the bidirectional lead screw, and the two nut blocks are fixedly connected to the two movable seats in a one-to-one correspondence. The motor can drive the two movable seats to move closer to or further away from each other along the second direction.

[0014] The second drive assembly includes a telescopic drive member, which is fixed to the first frame and located below the first conveying mechanism. The baffle is fixed to the telescopic end of the telescopic drive member, and the telescopic drive member can drive the baffle to pass through the gap between the two rollers to extend above the first conveying mechanism.

[0015] In some possible implementations, a first sensor is provided on the clamping assembly for detecting whether the housing has reached between the two clamping assemblies, and the first sensor is signal-connected to the first conveying mechanism and the first driving assembly;

[0016] The clamping assembly is provided with a first limit switch for contacting the side of the housing, and the first limit switch is signal-connected to the first drive assembly.

[0017] In some possible implementations, a second sensor is provided on the first frame, the second sensor being close to and upstream of the baffle mechanism, for detecting whether the box is approaching the baffle mechanism; the second sensor is signal-connected to the baffle mechanism and the first conveying mechanism to block the box upstream of the baffle.

[0018] On the other hand, this utility model provides a corner sealing equipment, including a feeding device, a corner sealing machine and a discharging device arranged sequentially along the production line direction. The feeding device includes a first conveying mechanism for conveying the box along a first direction. The corner sealing equipment also includes a box position correction device as described in any of the above schemes. The box position correction device is located between the outlet of the first conveying mechanism and the inlet of the corner sealing machine.

[0019] In some possible implementations, the feeding device further includes:

[0020] The third conveying mechanism is located upstream of the first conveying mechanism and is used to convey the longitudinally placed box to the first conveying mechanism along the first direction.

[0021] The first reversing mechanism is telescopically disposed below the first conveying mechanism and located upstream of the baffle mechanism. The first reversing mechanism is used to adjust the longitudinally placed box on the first conveying mechanism to be horizontally placed, so that the box is conveyed to the baffle mechanism in a horizontally placed state.

[0022] In some possible implementations, the first conveying mechanism includes a first frame and a plurality of rollers rotatably mounted on the first frame, the rollers extending along a second direction;

[0023] The first reversing mechanism includes a lifting assembly, a rotating assembly, and a bracket. The lifting assembly is fixed to the first frame, and its output end is movable in a third direction. The rotating assembly is fixed to the output end of the lifting assembly, and the bracket is fixed to the rotating assembly. The bracket is used to support the box, the lifting assembly is used to lift the box above the first conveying mechanism, and the rotating assembly is used to rotate the box.

[0024] In some possible implementations, the first rack is also provided with an information identification device, which is located on both sides of the first reversing mechanism and is used to detect the label information on the box. The information identification device is signal connected to the first reversing mechanism.

[0025] In some possible implementations, a third sensor is also provided on the first frame, the third sensor being positioned opposite the first reversing mechanism, for detecting whether the housing has reached the first reversing mechanism, and the third sensor being signal-connected to the first reversing mechanism;

[0026] A fourth sensor is installed on the first frame. The fourth sensor is located at the entrance of the first conveying mechanism and is used to detect whether the box is being conveyed to the first conveying mechanism. The fourth sensor is signal-connected to the first conveying mechanism.

[0027] The beneficial effects of this utility model are:

[0028] The box position correction device provided by this utility model includes a connecting mechanism and a baffle mechanism. The connecting mechanism receives the box output by the first conveying mechanism and securely clamps the box from both sides using two sets of clamping components. The second conveying mechanism then drives the box forward or backward in a first direction to achieve further transport of the box. The baffle mechanism is located upstream of the connecting mechanism and extends in a third direction above the first conveying mechanism to block the movement of the box. After the connecting mechanism clamps the box, by driving the box backward in the first direction, the rear side of the box abuts against the extended baffle, thereby correcting the position of the box using the plane of the baffle. This prevents the box from tilting forward or backward, which could affect the subsequent corner adhesive application.

[0029] The corner sealing equipment provided by this utility model, after applying adhesive to the center of the top and bottom of the box, and before applying adhesive to the corners of the box, uses a box position correction device to correct the position of the box, ensuring that the box enters the corner sealing machine in the correct orientation, thereby improving the accuracy of applying tape to the corners of the box and effectively improving the corner sealing quality of the box.

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0046] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0047] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0048] In the description of this utility model, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are merely used for distinction in description and have no special meaning.

[0049] like Figures 1 to 9 As shown, this embodiment provides a corner sealing device, including a feeding device, a box position correction device 200, a corner sealing machine 300 and a discharging device arranged sequentially along the production line direction.

[0050] The feeding device includes a third conveying mechanism 130 and a first conveying mechanism 110 arranged sequentially along the production line direction. The third conveying mechanism 130 is used to convey the longitudinally placed box 500 (i.e., the length direction of the box 500 is parallel to the first direction) along the first direction, so as to transport the box 500 to the first conveying mechanism 110. In this embodiment, since the length dimension of the box 500 is relatively large, conveying the box 500 along the longitudinal direction facilitates the limiting of the box 500, effectively prevents the box 500 from tipping over, and improves the transmission speed. The first conveying mechanism 110 is used to receive the longitudinally placed box 500 conveyed by the third conveying mechanism 130 and continue to convey the box 500 along the first direction. A first reversing mechanism 120 is provided below the first conveying mechanism 110. The first reversing mechanism 120 can extend above the first conveying mechanism 110 to adjust the longitudinally placed box 500 on the first conveying mechanism 110 to a horizontally placed position (i.e., the length direction of the box 500 is perpendicular to the first direction), so that the box 500 can continue to be conveyed forward in a horizontally placed posture. In this embodiment, by adjusting the box 500 to a horizontally placed position, it is convenient for the corner sealing machine 300 to simultaneously perform adhesive application on the four corners of the box 500, thereby improving sealing efficiency. It should be noted that in this embodiment, the width of the first conveying mechanism 110 is greater than the length of the box 500, the width of the third conveying mechanism 130 is greater than the width of the box 500, and the width of the first conveying mechanism 110 is greater than the width of the third conveying mechanism 130, so as to better adapt to the conveying posture of the box 500.

[0051] In existing technology, after applying adhesive to the center of the top and bottom of the box 500, the folded edge at the bottom of the box 500 bulges due to its own stress. This causes the box 500 to tilt to both sides during transport, especially for boxes with a large length-to-width ratio. When the box 500 is placed horizontally for transport, the tilting problem is more severe due to the driving force of the conveyor mechanism. This leads to problems such as tape misalignment and uneven tape application when the box 500 enters the corner sealing machine for adhesive application, seriously affecting the sealing effect. To address this, this embodiment provides a box position correction device 200 between the outlet of the first conveyor mechanism 110 and the inlet of the corner sealing machine 300. The box position correction device 200 can correct the posture of the box 500 conveyed by the first conveying mechanism 110 to ensure that the box 500 enters the corner sealing machine 300 in the correct placement posture (i.e., the side of the box 500 is perpendicular to the conveying surface of the first conveying mechanism 110), thus avoiding the box 500 from affecting the subsequent corner adhesive application effect due to tilting forward or backward.

[0052] The corner sealing machine 300 of this embodiment includes four sets of adhesive application mechanisms 330 (top, bottom, left, and right) for automatically applying tape to the four corners of the carton 500. In the prior art, for non-standard rectangular cartons, due to their non-standard length-width-height ratio, multiple manual adjustments are required when using conventional corner sealing equipment, which is cumbersome, inconvenient, and affects production efficiency. Therefore, the corner sealing machine 300 of this embodiment also includes a horizontal adjustment mechanism 340 and a vertical adjustment mechanism 350. The horizontal adjustment mechanism 340 adjusts the horizontal spacing of the left and right adhesive application mechanisms 330, and the vertical adjustment mechanism 350 adjusts the vertical spacing of the top and bottom adhesive application mechanisms 330. By automatically adjusting the vertical and horizontal spacing of the four sets of adhesive application mechanisms 330, it can adapt to various sizes and specifications of carton 500, offering strong applicability and covering various standard and non-standard cartons. It is also convenient to use, highly efficient, and avoids the tedious manual adjustments.

[0053] The discharge device is located at the outlet of the corner sealing machine 300, and includes a fifth conveying mechanism 410 and a sixth conveying mechanism 430 arranged sequentially along the production line direction. The fifth conveying mechanism 410 is located downstream of the corner sealing machine 300 and is used to convey the horizontally placed boxes 500 output from the corner sealing machine 300 along a first direction. A second reversing mechanism 420 is located below the fifth conveying mechanism 410, extending above it to adjust the horizontally placed boxes 500 on the fifth conveying mechanism 410 to a vertically placed position, allowing the boxes 500 to continue being conveyed forward in a vertically positioned posture. The sixth conveying mechanism 430 is located downstream of the fifth conveying mechanism 410 and is used to convey the vertically placed boxes 500 output from the fifth conveying mechanism 410 along a first direction. It should be noted that in this embodiment, the width of the fifth conveying mechanism 410 is greater than the length of the box 500, the width of the sixth conveying mechanism 430 is greater than the width of the box 500, and the width of the fifth conveying mechanism 410 is greater than the width of the sixth conveying mechanism 430, so as to better adapt to the conveying posture of the box 500.

[0054] Specifically, the first conveying mechanism 110 in this embodiment is a roller conveyor line, which includes a first frame 111, a motor fixed on the first frame 111, and a plurality of rollers 112 rotatably mounted on the first frame 111. The rollers 112 extend along a second direction, which is perpendicular to the first direction. The motor drives the rollers 112 to rotate through a sprocket and chain mechanism, thereby realizing the transmission of the box 500 along the first direction. Furthermore, each of the rollers 112 has a double-row sprocket fixed at its end. Adjacent rollers 112 are driven by chains, so that the sprockets can be meshed and linked by the chains to realize the rotation of each roller 112. The transmission is smooth and the speed adjustment is convenient. Similarly, the third conveying mechanism 130, the fourth conveying mechanism 320, and the fifth conveying mechanism 410 also adopt roller conveyor lines, and their specific structures are similar to those of the first conveying mechanism 110. This embodiment will not describe them in detail.

[0055] Furthermore, the third conveying mechanism 130 is provided with first limiting rods 131 on both sides. Both first limiting rods 131 extend along the first direction, and the distance between them is adjustable. This distance forms a conveying channel for the box 500 to pass longitudinally. After the box 500 enters the conveying channel, it can be effectively limited, thus allowing for more stable forward conveying. Similarly, the sixth conveying mechanism 430 is provided with second limiting rods 431 on both sides. Both second limiting rods 431 extend along the first direction, and the distance between them is adjustable. These rods are used to limit the box 500 output after the adhesive application is completed.

[0056] Optionally, the first reversing mechanism 120 in this embodiment includes a lifting component 121, a rotating component 122, and a bracket 123. The lifting component 121 is fixed to the first frame 111, and its output end is movable along a third direction. The rotating component 122 is fixed to the output end of the lifting component 121, and the bracket 123 is fixed to the rotating component 122. The top of the bracket 123 is used to support the box 500. In this embodiment, the third direction is perpendicular to the first and second directions. Specifically, the third direction is vertical. When the box 500 is conveyed by the first conveying mechanism 110 to the top of the bracket 123, the lifting component 121 first drives the box 500 to rise above the first conveying mechanism 110, and then the rotating component 122 drives the box 500 to rotate, thereby realizing the reversing operation of the box 500. Specifically, the aforementioned lifting assembly 121 includes a cylinder, and the rotating assembly 122 is fixed to the telescopic end of the cylinder; the rotating assembly 122 includes a motor, which is connected to the bracket 123 via a transmission assembly to drive the bracket 123 to rotate. Specifically, as... Figure 7As shown, the bracket 123 includes a rotating base 1231, a transverse support plate 1232, and a longitudinal support plate 1233. The rotating base 1231 is fixed to the output end of the rotating assembly 122. The transverse support plate 1232 and the longitudinal support plate 1233 are both fixed to the rotating base 1231, and both the transverse support plate 1232 and the longitudinal support plate 1233 are perpendicular to the conveying surface of the first conveying mechanism 110. The transverse support plate 1232 extends along a second direction, and the longitudinal support plate 1233 extends along a first direction. The structure of the bracket 123 better supports the box 500, increasing the placement stability of the box 500. Figure 8 As shown, in accordance with the structure of the bracket 123, the several rollers 112 on the first conveying mechanism 110 are divided into two sub-rollers 1121 along the second direction. The left sub-roller 1121 is rotatably mounted on the left side of the first frame 111, and the right sub-roller 1121 is rotatably mounted on the right side of the first frame 111. There is a clearance area between the left and right sub-rollers 1121. The width of the clearance area is greater than the diameter of the rotating seat 1231, allowing the rotating seat 1231 and the longitudinal support plate 1233 to pass through it. The transverse support plate 1232 passes through the gap between adjacent sub-rollers 1121. The above arrangement facilitates the smooth movement of the bracket 123 along the third direction, enabling the bracket 123 to achieve stepless rotation after extending above the first conveying mechanism 110, thereby achieving free rotation of the box 500 in both directions (360 degrees forward and reverse).

[0057] Furthermore, a third sensor 150 is also provided on the first frame 111. The third sensor 150 is positioned opposite the first reversing mechanism 120 and is used to detect whether the housing 500 has reached the first reversing mechanism 120. The third sensor 150 is signal-connected to the first reversing mechanism 120. When the third sensor 150 detects that the housing 500 has reached the first reversing mechanism 120, the third sensor 150 sends a signal to the controller. The controller controls the first reversing mechanism 120 to operate, causing the housing 500 to rise by a cylinder and to turn by a motor, thereby rotating the longitudinally placed housing 500 to a horizontally placed position. It should be noted that the second reversing mechanism 420 has a similar structure to the first reversing mechanism 120, and will not be described in detail in this embodiment.

[0058] Furthermore, since the incoming direction of the box 500 is not fixed, but in actual operation it is necessary for the side of the box 500 with the barcode to face a fixed direction, this embodiment also provides information identification devices 140 on both sides of the first reversing mechanism 120. These devices are used to identify the labels on the box 500 to determine the country of origin, size, and orientation of the label, so as to determine whether the orientation of the box 500 needs to be adjusted based on the identification results. The information identification device 140 is signal-connected to the first reversing mechanism 120. When one side of the information identification device 140 detects the label information of the box 500, it can send a signal to the controller. The controller determines whether the placement orientation of the box 500 needs to be corrected. If correction is required, it controls the first reversing mechanism 120 to rotate the box 500. Optionally, the information identification device 140 is a barcode scanner, which has a simple structure and reliable scanning capability.

[0059] Optionally, a fourth sensor 160 is also installed on the first frame 111. The fourth sensor 160 is located at the entrance of the first conveyor mechanism 110 and is used to detect whether a box 500 is input into the first conveyor mechanism 110, so as to control the operation of the production line according to the conveying status of the box 500. The fourth sensor 160 is signal-connected to the first conveyor mechanism 110. When the fourth sensor 160 detects that no box 500 has been input for a long time, it sends a signal to the controller, and the controller controls the first conveyor mechanism 110 to stop, thereby achieving the effect of saving power energy.

[0060] The housing position correction device 200 of this embodiment includes a connecting mechanism 210 and a baffle mechanism 220. The connecting mechanism 210 is located at the outlet of the first conveying mechanism 110, and includes a first driving assembly 211 and two clamping assemblies arranged opposite each other along a second direction. The first driving assembly 211 is used to drive the two clamping assemblies to move along the second direction to clamp the housing 500 from both sides. Specifically, the clamping assembly includes a movable seat 212 and a second conveying mechanism 213. The movable seat 212 is movably arranged on the first frame 111 along the second direction, and the movable seat 212 is movably inserted through a portion of the roller 112 of the first conveying mechanism 110. The first driving assembly 211 is fixed to the first frame 111 and drivenly connected to the movable seat 212. Specifically, the first drive assembly 211 includes a motor fixed to the first frame 111 and a bidirectional lead screw 2111 connected to the motor for transmission. Nut blocks 2112 are screwed onto the two threaded rods of the bidirectional lead screw 2111, and the two nut blocks 2112 are fixedly connected to the two movable seats 212 in a one-to-one correspondence. The motor can drive the two movable seats 212 to move closer to or further away from each other along a second direction. In this embodiment, the first drive mechanism uses one motor to drive two movable seats 212 to move simultaneously, resulting in a simple structure, smooth movement, and convenient control. The second conveying mechanism 213 is mounted on the movable base 212. The second conveying mechanism 213 includes a first housing 2131 fixed to the movable base 212 and a first conveyor belt 2132 disposed within the first housing 2131. The first conveyor belt 2132 extends and drives along a first direction, and its conveying surface is positioned opposite to the left / right sides of the housing 500, allowing it to adhere to the left / right sides of the housing 500. The two sets of first conveyor belts 2132 can clamp the housing 500 from both sides and drive it forward or backward along the first direction. In this embodiment, the housing 500 is clamped and driven by the first conveyor belt 2132, resulting in a compact structure, light weight, uniform load distribution, and stable speed.

[0061] refer to Figure 1 , Figure 4 and Figure 9The baffle mechanism 220 is located below the first conveying mechanism 110 and upstream of the connecting mechanism 210. The baffle mechanism 220 includes a second drive assembly 221 and a baffle 222. The plane of the baffle 222 is parallel to a third direction (i.e., the vertical direction). The second drive assembly 221 is used to drive the baffle 222 to move along the third direction to extend above the first conveying mechanism 110. When the two sets of second conveying mechanisms 213 drive the box 500 to retreat to the baffle mechanism 220, the rear side of the box 500 can abut against the baffle 222 to correct the position of the box 500. Specifically, the second drive assembly 221 includes a telescopic drive member, which is fixed to the first frame 111 and located below the first conveying mechanism 110. The baffle 222 is fixed to the telescopic end of the telescopic drive member. The telescopic drive member can drive the baffle 222 to pass through the gap between the two rollers 112 of the first conveying mechanism 110 to extend above the first conveying mechanism 110. The telescopic drive component can be a pneumatic cylinder, hydraulic cylinder, electric cylinder, etc. In this embodiment, a pneumatic cylinder is preferred due to its simple structure and reliable operation. Furthermore, this embodiment provides two sets of baffle mechanisms 220, spaced apart along the second direction, to improve the accuracy of position correction of the housing 500. It should be noted that the baffle mechanism 220 is located downstream of the first reversing mechanism 120. This arrangement allows the housing 500 to first pass through the first reversing mechanism 120 for reversal, and then be transported to the baffle mechanism 220 in a laterally placed state.

[0062] In this embodiment, the clamping assembly is further equipped with a first sensor 230 for detecting whether the housing 500 has reached between the two clamping assemblies. The first sensor 230 is signal-connected to the first conveying mechanism 110 and the first driving assembly 211. When the first sensor 230 detects that the housing 500 has entered between the two clamping assemblies, it sends a signal to the controller. The controller controls the first conveying mechanism 110 to stop operating and controls the first driving assembly 211 to operate, so that the two sets of clamping assemblies move closer to each other and clamp the housing 500. Specifically, the first sensor 230 is a photoelectric sensor, which has a short response time and high resolution, thus improving detection accuracy. Further, the clamping assembly is equipped with a first limit switch 240 for contacting the left / right side of the housing 500. The first limit switch 240 is signal-connected to the first driving assembly 211. When the two clamping assemblies move closer to each other and clamp the housing 500, the first limit switch 240 can be triggered and sends a signal to the controller. The controller controls the first driving assembly 211 to stop operating, preventing further damage to the housing 500.

[0063] In addition, a second sensor 250 is installed on the first frame 111. The second sensor 250 is close to the baffle mechanism 220 and located upstream of the baffle mechanism 220. It is used to detect whether a box 500 is approaching the baffle mechanism 220. The second sensor 250 is signal connected to the baffle mechanism 220 and the first conveying mechanism 110. When the second sensor 250 detects that the box 500 is about to reach the baffle mechanism 220, it sends a signal to the controller. The controller controls the first conveying mechanism 110 to stop and controls the baffle 222 to extend upward to block the box 500 upstream of the baffle 222 and wait. After the corner sealing machine 300 finishes applying adhesive to the previous box 500, the controller controls the baffle 222 to retract downward so that the next box 500 can continue to be conveyed forward.

[0064] Because the top and bottom of the box 500 are raised before the corners are sealed, the box 500 may tilt forward or backward. Therefore, it is necessary to correct the box 500 from a tilted state to a vertical state before it enters the corner sealing machine 300. The correction process in this embodiment is as follows: The clamping assembly first performs a clamping action to clamp the box 500, and at the same time, the first conveying mechanism 110 stops running. Then, the second conveying mechanism 213 drives the box 500 to move backward until the rear side of the box 500 abuts against the baffle 222, thereby using the plane where the baffle 222 is located to correct the position of the box 500, so as to adjust the tilted box 500 to a vertical state. After that, the second conveying mechanism 213 moves forward again, driving the box 500 into the corner sealing machine 300. When the box 500 reaches the corner sealing machine 300, the corner sealing machine 300 clamps the box 500, and then the second conveying mechanism 213 releases the box 500. In this embodiment, by setting up a box position correction device 200, the box 500 enters the corner sealing machine 300 in the correct placement posture, which improves the accuracy of applying tape to the corners of the box 500 and effectively improves the corner sealing quality of the box 500.

[0065] It should be noted that the box position correction device 200 in this embodiment can be used not only in corner sealing equipment, but also in other scenarios where the position of the box 500 needs to be adjusted. It can also solve the problem of the box 500 tilting forward and backward due to uneven placement.

[0066] Specifically, the corner sealing machine 300 of this embodiment includes a second frame 310 and four sets of fourth conveying mechanisms 320 disposed on the second frame 310. The four sets of fourth conveying mechanisms 320 correspond to the four corners of the box 500 (top, bottom, left, and right), and form a transmission channel between the four sets of fourth conveying mechanisms 320 for the box 500 to pass through. Specifically, each set of fourth conveying mechanisms 320 includes a second housing 321 and a second conveyor belt 322 extending in a first direction disposed within the second housing 321. The conveying surface of the second conveyor belt 322 corresponds to the upper / lower side of the box 500, and is used to drive the box 500 to move in the first direction. Four sets of adhesive applicators 330 are correspondingly disposed on the second housing 321 of the four sets of fourth conveying mechanisms 320. The lateral adjustment mechanism 340 and the vertical adjustment mechanism 350 are mounted on the second frame 310. The lateral adjustment mechanism 340 is used to adjust the lateral spacing between the left and right fourth conveying mechanisms 320; the vertical adjustment mechanism 350 is used to adjust the vertical spacing between the upper and lower fourth conveying mechanisms 320. Optionally, both the lateral adjustment mechanism 340 and the vertical adjustment mechanism are driven by a motor and a lead screw and nut mechanism, which will not be elaborated further in this embodiment.

[0067] The corner sealing machine 300 of this embodiment also includes third limiting rods 323. Two third limiting rods 323 are respectively fixed to the second housing 321 of the two lower sets of fourth conveying mechanisms 320. The two third limiting rods 323 can move laterally with the second housing 321 to limit the box 500 from both sides. Further, a second limit switch 371 is also provided on the third limiting rod 323. The second limit switch 371 is signal-connected to the lateral adjustment mechanism 340 and is used to control the distance between the fourth conveying mechanisms 320 on the left and right sides to adapt to the long side dimension of the box 500. Simultaneously, a third limit switch 372 is also provided on the second housing 321. The third limit switch 372 is signal-connected to the vertical adjustment mechanism 350 and is used to control the distance between the fourth conveying mechanisms 320 on the upper and lower sides to adapt to the height dimension of the box 500.

[0068] The adhesive applicator 330 in this embodiment is used to apply adhesive tape to the box 500. It includes a fixed plate, adhesive wheels, rollers, guide wheels, front rocker arm, rear rocker arm, pressure roller, and cutter assembly. The specific configuration of the mechanism can be found in the relevant content of the prior art, and will not be described in detail in this embodiment.

[0069] Furthermore, the corner sealing machine 300 also includes a fixed side brush 361 and a movable brush 362. The fixed side brush 361 is fixed to the adhesive applicator 330 and is used to smooth the tape on the left and right sides of the box 500. The movable brush 362 is driven by a motor to rotate and is used to smooth the tape extending from the rear side of the box 500. In addition, the corner sealing machine 300 also includes a fourth limit switch 373. When the tape is applied to the box 500, the fourth limit switch 373 can be triggered. The fourth limit switch 373 sends a signal to the controller, which controls the motor of the movable brush 362 to rotate and smooth the tape on the rear side of the box 500. Optionally, the corner sealing machine 300 also includes an excess material sensor 374 to sense the amount of remaining tape on the tape roller, so as to notify the staff in time to prepare to replace the material. Optionally, the corner sealing machine 300 also includes an unsealed sensor 375, which is mounted on a self-made roller of the tape-applying mechanism 330. This self-made roller is driven by the tape to rotate. Therefore, by sensing whether the self-made roller is rotating, it can be determined whether the tape-applying mechanism 330 is outputting tape. If the self-made roller is not detected to be rotating, it means that there is no tape output at this time. Therefore, the box 500 needs to be controlled to stop the transmission, and the sealing tape needs to be manually inspected to prevent defective products from leaving the equipment. Furthermore, the corner sealing machine 300 is also equipped with casters 380 at the bottom to facilitate the movement of the corner sealing machine 300.
