Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] It should also be understood that the terms used in this specification of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. As used in this specification of the present utility model and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0034] It should also be further understood that the term "and / or" used in the specification and appended claims of the present utility model refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0035] Combined Figure 1 And Figure 2 As shown, an embodiment of the present utility model provides a box cover folding device, which includes a bracket assembly 10 and two folding cover assemblies 20. The bracket assembly 10 includes an operation area 11 for placing a packing box 100. Each folding cover assembly 20 includes a cover pushing member 21 and a cover pressing member 22. The two cover pushing members 21 are respectively arranged on both sides of the bracket assembly 10, and the two cover pressing members 22 are respectively arranged on both sides of the top of the bracket assembly 10. The two cover pushing members 21 can respectively push the box covers on both sides of the packing box 100 placed in the operation area 11, and the two cover pressing members 22 can respectively press the box covers after being pushed on both sides of the packing box 100.

[0036] In this embodiment, the operation area 11 of the bracket assembly 10 is used to place the packing box 100, and the box cover folding process of the packing box 100 is completed within the operation area 11. Each folding cover assembly 20 includes a cover pushing member 21 and a cover pressing member 22. The cover pushing member 21 is installed on both sides of the bracket assembly 10 and is used to perform a cover pushing operation on the box covers on both sides of the packing box 100 in the operation area 11. After the packing box 100 is placed in the operation area 11, the two cover pushing members 21 respectively apply a thrust force to the box covers on both sides of the packing box 100 from the outside to push the box covers inward for folding. The cover pressing member 22 is arranged on both sides of the top of the bracket assembly 10 and is located above the cover pushing member 21. When the cover pushing member 21 completes the cover folding operation, the two cover pressing members 22 start to perform a cover pressing operation on the folded box covers, and further press the box covers into the interior of the packing box 100 by applying a downward pressure, so as to complete the box cover folding process. It should be noted that the above-mentioned two cover pressing members 22 are respectively arranged on both sides of the top of the bracket assembly 10, and the setting does not necessarily mean directly connected to both sides of the top of the bracket assembly 10, but means that its position is on both sides of the top of the bracket assembly 10. Of course, the cover pressing member 22 can be directly connected to the top of the bracket assembly 10 or located at the top of the bracket assembly 10 through the connection of other mechanisms.

[0037] Through the above structural design, the box cover folding device can effectively achieve the automatic folding operation of the box covers on both sides of the packaging box. The combined use of the lid pusher 21 and the lid presser 22 simplifies and streamlines the entire lid folding process, improving the packaging efficiency and operation accuracy. In practical applications, the output of box cover folding can be increased by more than half. For example, in the past, manual operation could only complete the box cover folding of N air conditioner indoor units per hour, but now it can complete the box cover folding of 2N air conditioner indoor units per hour. The box cover folding device can complete the automatic operation with simple operations, without the need for complex manual operations. At the same time, the box cover folding device has high safety and does not require facing the safety hazards caused by manual operations.

[0038] Combined Figure 3 and Figure 4 As shown, in one embodiment, each lid pusher 21 includes a lid pusher mounting frame 211, a lid pusher mounting frame driving part 212, and a lid pusher part 213. The lid pusher mounting frame driving part 212 is arranged on the side of the bracket assembly 10. The lid pusher mounting frame 211 is arranged on the lid pusher mounting frame driving part 212, and the lid pusher part 213 is arranged on the lid pusher mounting frame 211. And the lid pusher mounting frame driving part 212 can drive the lid pusher mounting frame 211 and the lid pusher part 213 to reciprocate in the direction of the operation area 11.

[0039] In this embodiment, the structure of each lid pusher 21 includes a lid pusher mounting frame 211, a lid pusher mounting frame driving part 212, and a lid pusher part 213. The lid pusher mounting frame driving part 212 is arranged on the side of the bracket assembly 10, and its function is to provide driving force for the lid pusher mounting frame 211. The lid pusher mounting frame 211 is installed on the lid pusher mounting frame driving part 212 and can move horizontally along with the action of the lid pusher mounting frame driving part 212. The lid pusher part 213 is fixed on the lid pusher mounting frame 211 and is mainly used to contact the box cover of the packaging box 100 and apply a thrust force to fold it inward. When the packaging box 100 is placed in the operation area 11, the lid pusher mounting frame driving part 212 is started. Through driving control, the lid pusher mounting frame driving part 212 drives the lid pusher mounting frame 211 and the lid pusher part 213 to reciprocate in the direction of the operation area 11, pushing the lid pusher mounting frame 211 and the lid pusher part 213 close to the box cover on the side of the packaging box 100, and through the contact between the lid pusher part 213 and the box cover, pushing the box cover towards the inside of the packaging box 100. The lid pusher mounting frame driving part 212 can be a cylinder or other power components.

[0040] In one embodiment, the lid pusher part 213 includes a lid pusher driving part 2131 and a connecting piece 2132. The lid pusher driving part 2131 is arranged on the lid pusher mounting frame 211, and one end of the connecting piece 2132 is connected to the lid pusher driving part 2131, and the other end of the connecting piece 2132 is used to push the box cover on the side of the packaging box 100 placed in the operation area 11.

[0041] In this embodiment, the push - cover driving part 2131 is fixedly installed on the push - cover mounting frame 211. The push - cover driving part 2131 is used to provide power to drive the connecting piece 2132 to complete the push - cover action. One end of the connecting piece 2132 is connected to the push - cover driving part 2131, and reciprocating motion is achieved through the driving force of the push - cover driving part 2131. The other end of the connecting piece 2132 is used to directly contact the side cover of the packing box 100 and apply a thrust force to push the cover inward for folding.

[0042] During the actual operation process, when the packing box 100 is placed in the operation area 11, first, the push - cover mounting - frame driving part 212 drives the push - cover mounting frame 211 and the push - cover part 213 to approach the side cover of the packing box 100 to complete the preliminary positioning. Then, the push - cover driving part 2131 is started to drive the connecting piece 2132 to approach the packing box 100. When the end of the connecting piece 2132 contacts the side cover of the packing box 100, the push - cover driving part 2131 continues to apply a thrust force to prompt the cover to fold inward and complete the push - cover operation. Through the coordinated action of the push - cover mounting - frame driving part 212 and the push - cover driving part 2131, the push - cover operation can be performed on the cover of the packing box 100, ensuring the stability of the folding process and adapting to packing boxes of different sizes. The way of preliminary positioning can be that one of the push - cover mounting - frame driving parts 212 on one side drives the push - cover mounting frame 211 and the push - cover part 213 to approach the side cover of the packing box 100 until the push - cover mounting frame 211 contacts one side of the packing box 100, and then continue to push the push - cover mounting frame 211 to make the opposite side of the packing box 100 contact the push - cover mounting frame 211 on the other side, thus completing the positioning. The push - cover driving part 2131 can be a cylinder or other power - equipped components.

[0043] In one embodiment, a positioning part 2111 is provided on the side of the push - cover mounting frame 211 close to the operation area 11.

[0044] In this embodiment, the main function of the positioning part 2111 is to assist in positioning the position of the packing box 100 to ensure that the packing box 100 is stably positioned within the operation area 11. When the packing box 100 is placed in the operation area 11, the positioning part 2111 approaches and contacts the side of the packing box 100 to determine the position of the packing box 100, ensuring that the packing box 100 is in the correct working position within the operation area 11, thereby avoiding the failure of the push - cover operation or incomplete folding of the cover caused by position deviation.

[0045] Specifically, the positioning part 2111 can be set as a positioning strip or a positioning block. In this embodiment, a positioning strip is adopted, such as Figure 3 and Figure 4As shown, two positioning bars are horizontally spaced on the push - cover mounting frame 211. When the positioning bars approach the packaging box 100, they can fit the surface of the packaging box 100, thus achieving a positioning effect. The number of the positioning parts 2111 can be set according to actual needs and is not limited here.

[0046] In an embodiment, a first buffer 21321 is provided at the other end of the connecting member 2132.

[0047] In this embodiment, the purpose of the first buffer 21321 is to provide a buffering effect on the lid of the packaging box 100 during the push - cover process, avoiding damage to the lid or the packaging box during the push - cover operation. The first buffer 21321 is fixed at the end of the connecting member 2132. When the push - cover driving part 2131 drives the connecting member 2132 to apply a thrust to the lid of the packaging box 100, the first buffer 21321 first contacts the lid. Since the first buffer 21321 is made of elastic or flexible material, it can effectively absorb the impact force generated during the push - cover process, reduce the direct impact and friction on the lid surface, and ensure the smooth progress of the push - cover process. This not only protects the integrity of the lid of the packaging box 100 from being damaged due to excessive mechanical thrust but also extends the service life of the connecting member 2132, improving the safety and reliability of the operation. As Figure 3 and Figure 4 shown, the other end of the connecting member 2132 is designed as a U - shape, and two first buffers 21321 are provided on each U - shaped end of the connecting member 2132.

[0048] In an embodiment, one of the capping members 22 includes a capping driving part 221 and a capping fixing frame 222. The capping fixing frame 222 is arranged at the top of one side of the bracket assembly 10, and the capping driving part 221 is arranged on the capping fixing frame 222. The output end of the capping driving part 221 is used to cap the lid of the packaging box 100 on one side after the push - cover operation.

[0049] In this embodiment, the output end of the gland pressing driving part 221 is in direct contact with the lid of the packaging box 100, applying a downward pressure. When the packaging box 100 is preliminarily pushed and folded by the lid pushing part 21, the lid is in a folded state. At this time, the gland pressing driving part 221 is activated, and a vertically downward pressure is applied through the output end to further press the folded lid into the interior of the packaging box 100, thus completing the gland pressing operation of the lid. With the stable support of the gland pressing fixing frame 222, the gland pressing driving part 221 can accurately align with the pushed and folded lid. The gland pressing driving part 221 can apply sufficient pressure to complete the full folding of the lid, while ensuring a smooth and stable folding process and avoiding the lid from rebounding. After the gland pressing operation is completed, the lid pushing mounting frame driving part 212 and the lid pushing driving part 2131 are retracted simultaneously to drive the corresponding lid pushing mounting frame 211 and the lid pushing part 213 to retract. The gland pressing driving part 221 itself also needs to retract. Due to the action of the friction inside the box body and the fatigue at the lid rotation shaft, it will maintain the pressed angle or slightly rebound. This process realizes the folding of the lid of the packaging box. The gland pressing driving part 221 can be a cylinder or other power components.

[0050] It should be noted that the setting forms of the two gland pressing parts 22 are different. One of the gland pressing parts 22 in this embodiment corresponds to Figure 3 the structure of the gland pressing part 22 shown, that is, the gland pressing part 22 and the lid pushing part 21 are in a separated state.

[0051] In one embodiment, the other gland pressing part 22 includes a gland pressing driving part 221. The gland pressing driving part 221 is arranged at the top of the corresponding lid pushing mounting frame 211, and the output end of the gland pressing driving part 221 is used to press the lid of the packaging box 100 on the other side after the lid is pushed.

[0052] In this embodiment, the other gland pressing part 22 corresponds to Figure 4 the structure of the gland pressing part 22 shown, that is, the gland pressing part 22 and the lid pushing part 21 are integrally arranged. When the packaging box 100 is pushed by the lid pushing part 21, the lid is in a preliminary folded state. At this time, the gland pressing driving part 221 is activated. The output end of the gland pressing driving part 221 is directly in contact with the already pushed and folded lid and applies a vertically downward pressure to further press the lid into the interior of the packaging box 100, thus completing the gland pressing operation. Since the gland pressing driving part 221 is arranged at the top of the lid pushing mounting frame 211 (that is, the gland pressing part 22 and the lid pushing part 21 are integrally arranged), the gland pressing part 22 can automatically adjust its position as the lid pushing mounting frame 211 moves, facilitating the coordination of the gland pressing operation and the lid pushing operation.

[0053] In one embodiment, the lid pushing mounting frame driving part 212 of at least one of the lid pushing parts 21 includes a servo module.

[0054] In this embodiment, the servo module can control the displacement of the output end and the applied pressure of the push cover mounting frame driving part 212 by receiving signals from the control system. This embodiment can set the push cover mounting frame driving part 212 in Figure 4 as the servo module. The servo module can control the displacement of the output end according to preset parameters, so as to adjust the position of the push cover mounting frame 211. Of course, other driving parts can also be set as the servo module, such as the push cover mounting frame driving part 212 in Figure 3 , or two capping driving parts 221, etc.

[0055] In one embodiment, a second buffer 2211 is provided at the output end of the capping driving part 221.

[0056] In this embodiment, the function of the second buffer 2211 is to provide buffering for the box cover during the capping process, so as to avoid damaging the box cover or the overall structure of the packaging box 100 when applying the capping force. The second buffer 2211 is fixed at the output end of the capping driving part 221. When the capping driving part 221 starts to perform the capping operation, the output end contacts the box cover of the packaging box 100. Since the second buffer 2211 is usually made of elastic or flexible materials, it can effectively absorb and disperse the force applied during the capping process, preventing the box cover from deforming or being damaged due to excessive capping force. As shown in Figure 3 and Figure 4 , one second buffer 2211 is provided at the output end of each of the two capping driving parts 221.

[0057] Combined with Figure 5 shown, in one embodiment, the bracket assembly 10 includes a support frame 12, a first limiting member 13, a second limiting member 14, a third limiting member 15 and a transmission part 16. Two push cover parts 21 are respectively arranged on opposite sides of the support frame 12, and two capping parts 22 are respectively arranged on the top of the support frame 12; the transmission part 16 is located at the bottom of the operation area 11, the first limiting member 13 and the second limiting member 14 are respectively arranged on opposite sides of the transmission part 16, and the third limiting member 15 is arranged at the end of the transmission direction of the transmission part 16.

[0058] In this embodiment, two push cover parts 21 are respectively arranged on opposite sides of the support frame 12 to ensure that the push cover operation can be performed on the two side box covers of the packaging box 100; while the two capping parts 22 are respectively located on the top of the support frame 12 and are used to perform the capping operation on the box cover after the push cover operation is completed. The transmission part 16 is located at the bottom of the operation area 11 and is responsible for driving the packaging box 100 to move within the operation area. During the operation, the transmission part 16 can convey the packaging box 100 from one end to the other end to realize the automatic push cover and capping operations of the box cover.

[0059] To ensure the precise positioning of the packing box 100 during the transmission process, the support assembly 10 is also provided with a plurality of limit members. The first limit member 13 and the second limit member 14 are respectively arranged on the opposite sides of the transmission part 16, and are used to limit the left and right positions of the packing box 100 during the transmission process, ensuring that the packing box 100 remains stable during the transmission process and does not shift. The third limit member 15 is located at the end of the transmission direction of the transmission part 16, and is responsible for limiting the packing box 100 when it moves to the set position, preventing it from exceeding the operation area 11, and providing positioning guarantee for subsequent lid-pushing and lid-pressing operations.

[0060] In this embodiment, the transmission part 16 is mainly a roller line. The length of the roller line determines the storage capacity of the packing box 100. The left limit part (i.e., the first limit member 13) and the right limit part (i.e., the second limit member 14) are installed at both ends of the roller line to guide and limit the packing box 100. A baffle (i.e., the third limit member 15) is installed at the end of the roller line to stop the packing box 100. The roller line does not need to stop, which is convenient for the front-row packing boxes 100 to continue flowing backward. A gantry (i.e., the support frame 12) is also fixed at the end of the roller line. The gantry is mainly welded by square tubes and plates, and the strength of the frame body needs to be ensured. The gantry is used to support the lid-pushing member 21 and the lid-pressing member 22.

[0061] In this embodiment, as Figure 2 shown, the lid-pushing members 21 and the lid-pressing members 22 on the left side form a fixed end, and the lid-pushing members 21 and the lid-pressing members 22 on the right side form a movable end. Among them, the lid-pushing mounting frame driving part 212 in the lid-pushing member 21 of the fixed end is arranged on the left side of the support assembly 10, and the lid-pressing fixing frame 222 in the lid-pressing member 22 of the fixed end is arranged on the left side of the top of the support assembly 10. That is, the lid-pressing member 22 and the lid-pushing member 21 of the fixed end move independently; the lid-pushing mounting frame driving part 212 in the lid-pushing member 21 of the movable end is arranged on the right side of the support assembly 10, and the lid-pressing driving part 221 in the lid-pressing member 22 of the movable end is arranged on the top of the lid-pushing mounting frame 211. That is, when the lid-pushing mounting frame driving part 212 pushes the lid-pushing mounting frame 211, it can drive both the lid-pushing part 213 and the lid-pressing member 22 to move together. During the folding process of the box lid, first, the lid-pushing mounting frame driving part 212 of the movable end drives the corresponding lid-pushing mounting frame to move to match the length of the packing box 100. For example, if the packing box 100 is shorter, it is necessary to drive the corresponding lid-pushing mounting frame 211 to move a greater distance toward the operation area 11. If the packing box 100 is longer, it is necessary to drive the corresponding lid-pushing mounting frame 211 to move a shorter distance toward the operation area 11, so that the left box lid of the packing box 100 is located below the lid-pressing member 22 of the fixed end; then the lid-pushing mounting frame driving part 212 of the fixed end drives the corresponding lid-pushing mounting frame 211 to move to position the packing box 100. In this way, the packing box 100 is clamped and fixed by the two lid-pushing mounting frames 211, so that the entire box lid folding device can adapt to packing boxes 100 of different lengths.

[0062] Combine the following Figures 6 to 10 The action process of the box cover folding device of this embodiment is specifically described as follows. The loading and unloading of the packaging box 100 is completed by a robot or other automated equipment. First, the length of the packaging box 100 required for production is confirmed, and the corresponding servo module parameters (that is, the parameters of the push cover mounting frame driving unit 212 at the movable end) are set according to the length of the packaging box 100. When the packaging box 100 reaches the baffle (such as Figure 6 As shown in FIG. 1 , the push cover mounting frame driving unit 212 at the movable end drives the push cover mounting frame 211 to gradually approach the packaging box 100 according to the servo module parameters, and then the push cover mounting frame driving unit 212 at the movable end drives the push cover mounting frame 211 to approach the packaging box 100. At this time, the packaging box 100 is contacted and clamped by the positioning parts 2111 on both sides (as shown in FIG. 1 ). Figure 7 As shown), then, the cover push driving parts 2131 on both sides drive the connecting member 2132 to extend, and the soft packing head (i.e., the first buffer member 21321) on the connecting member 2132 contacts the box cover of the packaging box 100, and the box cover folds inward at a certain angle (as shown). Figure 8 As shown), then, the corresponding cover driving parts 221 on both sides extend out, and the soft packing head (i.e., the second buffer member 2211) on the cover driving part 221 contacts the box cover of the packaging box 100, and the box cover is greatly folded downward at a certain angle (as shown in FIG. Figure 9 After the folding step is completed, the cover pusher mounting frame driving unit 212, the cover pusher driving unit 2131 and the cover pressing driving unit 221 are all retracted (as shown in FIG. Figure 10 As shown), due to the internal friction of the packaging box 100 and the fatigue of the box cover shaft, the box cover will maintain the angle after being pressed down or rebound slightly, and the rear material picking device will take away the packaging box 100 and wait for the next packaging box 100 to reach the baffle.
