Description

Technical Field

[0001] The present invention relates to the technical field of washing machine packaging equipment, and particularly relates to a packaging system for washing machine production. Background Art

[0002] A washing machine is a common household electrical appliance in people's lives. After it is produced, it needs to be internally and externally packaged before leaving the factory. Specifically, after the washing machine is produced, it is first necessary to set an inner bag, then set upper and lower protective frames, then set an outer box, seal the outer box, and finally tie straps to complete the packaging of the washing machine. In these packaging procedures, if all are manually operated, the workload of workers is too large and requires a lot of effort. For example, setting the lower protective frame requires lifting the washing machine, resulting in low production efficiency. And some production lines divide the packaging process into discontinuous multi-stage processes and still rely on manual handling. Although the workload of workers has been reduced to a certain extent, handling a washing machine with a certain weight still brings a certain burden to workers, and the manual workload is still relatively large and needs to be improved.

[0003] Based on this, the present invention provides a packaging system for washing machine production, which can integrate the operations of setting the upper and lower protective frames of the washing machine, setting the outer box, and gluing and sealing the outer box cover of the washing machine. During this process, there is no need for manual handling of the washing machine, which greatly reduces the manual workload and improves production efficiency. Summary of the Invention

[0044] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. Specific embodiments

[0045] Please refer to Figures 1 to 14 In a preferred embodiment of the present invention, a packaging system for washing machine production includes a main conveying assembly 1 for conveying a washing machine, a support platform 2, a protection assembly 6, a first clamping assembly 3, a bottom frame feeding assembly 4, a top frame feeding assembly 5, a second clamping assembly 7, an outer box installation platform 8, a box body placing platform 9, a box body installation assembly 10, and a box cover 11.5.5 sealing glue assembly 11.

[0046] The main conveying component 1 is sequentially provided with a support platform 2 and a protection component 6 in its conveying direction.

[0047] The support platform 2 includes a support tabletop 2.1 and a support lifting member 2.2. The support tabletop 2.1 is located directly below the upper conveying surface of the main conveying component 1 and is installed on the movable end of the support lifting member 2.2 so as to abut against the upper conveying surface of the main conveying component 1 or be spaced from the upper conveying surface of the main conveying component 1 under the action of the support lifting member 2.2, so that the support tabletop 2.1 does not affect the conveying of the main conveying component 1 and can also support the washing machine, facilitating the inner packaging of the washing machine. Specifically, the main conveying component 1 conveys the washing machine to directly above the support tabletop 2.1, and the support tabletop 2.1 is lifted upward, and the washing machine can be supported by the support tabletop 2.1, with a hard support instead of the soft support of the conveyor belt of the main conveying component 1. Please refer to Figure 5 , in this embodiment, the support tabletop 2.1 is arranged between the upper conveying surface and the lower conveying surface of the main conveying component 1, and the support lifting member 2.2 is located below the lower conveying surface of the main conveying component 1. Its movable end is connected to the support tabletop 2.1 through a support link, and the support link does not interfere with the conveyor belt of the main conveying component 1. In this way, the support tabletop 2.1 can be suspended and installed between the upper conveying surface and the lower conveying surface of the main conveying component 1 and can be lifted and lowered between the two. Preferably, the support links are arranged on the opposite sides of the support tabletop 2.1, and the opposite sides are the two sides in the width direction of the conveyor belt of the main conveying component 1, and the support links on both sides are connected to the support lifting member 2.2. In the present invention, the support lifting member 2.2 can be a lifting structure such as an electric push rod, a cylinder, a hydraulic cylinder, etc., or other lifting structures, and no specific limitation is made here.

[0048] The first clamping assembly 3 is arranged on one side of the support platform 2, and this side is one side in the width direction of the conveyor belt of the main conveyor assembly 1; the first clamping assembly 3 has a first clamping portion 3.1 for clamping the washing machine conveyed by the main conveyor assembly 1 to directly above the support platform 2, a first clamping driving portion 3.2 for driving the first clamping portion 3.1 to clamp or release, and a first clamping lifting portion 3.3 for driving the first clamping portion 3.1 to lift and lower.

[0049] The first clamping assembly 3 is used to clamp the washing machine directly above the support platform 2, and can lift and lower the clamped washing machine to lift the suspended washing machine, so as to facilitate the bottom frame feeding assembly 4 to push the protective bottom frame on its bottom frame conveying assembly 4.1 onto the conveying surface of the main conveyor assembly 1, and then lower the washing machine, and cooperate with the support platform 2 to rise and abut for support, so that the protective bottom frame can be stably sleeved on the bottom of the washing machine. Then, the top frame feeding assembly 5 clamps the protective top frame on the top frame conveying assembly 5.1 through the top frame clamping assembly 5.2 and moves it to directly above the washing machine under the action of the top frame horizontal moving assembly 5.3, and then sleeves the protective top frame on the washing machine under the action of the top frame lifting assembly 5.4, and makes the protective top frame and the protective bottom frame be clamped and connected into a complete protective cover. During the process of the top frame feeding assembly 5 sleeving the protective top frame, the first clamping assembly 3 releases the clamping action on the washing machine, and the support platform 2 still supports the washing machine, and jointly acts with the top frame feeding assembly 5 to realize the sleeving of the protective top frame.

[0050] In the present invention, the first clamping assembly 3 can clamp and lift. Among them, the first clamping portion 3.1 plays a clamping role. In this embodiment, the specific structure of the first clamping portion 3.1 is: Please refer to Figure 6, the first clamping part 3.1 is two first clamping plates, the plate surfaces of the two first clamping plates are both vertically arranged and face each other; both first clamping plates are connected to the first clamping driving part 3.2, and the two move towards each other under the action of the first clamping driving part 3.2 to clamp or move away from each other to release the clamping. The first clamping driving part 3.2 can be two telescopic structures, such as electric push rods, cylinders, hydraulic cylinders and other structures, or a two-way telescopic structure, or a two-way sliding structure composed of a motor-screw rod assembly.

For example, a first clamping lifting platform is installed on the top of the first clamping lifting part 3.3, and the first clamping driving part 3.2 and the first clamping part 3.1 are both installed on the first clamping lifting platform. The specific structure of the first clamping lifting part 3.3 can be an electric push rod, a hydraulic cylinder, a pneumatic cylinder, a linear stepping motor, a motor-screw rod structure, etc., and is not specifically limited.

To facilitate the conveying of the protective bottom frame, a bottom frame loading connection platform 4.4 is provided between the two. The tabletop of the bottom frame loading connection platform 4.4 is flush with the upper conveying surface of the bottom frame conveying assembly 4.1. Preferably, the tabletop of the bottom frame loading connection platform 4.4 is composed of rollers or wheels to form a rolling platform. To prevent the protective bottom frame on the bottom frame conveying assembly 4.1 from being conveyed too far, a bottom frame limiting baffle 4.3 is vertically provided at the conveying end of the bottom frame conveying assembly 4.1. The length direction of the bottom frame limiting baffle 4.3 is the width direction of the bottom frame conveying assembly 4.1 to intercept the protective bottom frame through the action of the bottom frame limiting baffle 4.3.

The specific structure is as follows:

[0054] In the present invention, the protective assembly 6 is spaced from the support platform 2 and is located on one side in the width direction of the conveyor belt of the main conveying assembly 1; please refer to Figure 9, the protection component 6 has a protection driving member and a protection frame 6.1. The protection driving member is used to drive the protection frame 6.1 away from or close to the middle of the conveying surface of the main conveying component 1; the protection frame 6.1 is located above the conveying surface of the main conveying component 1, and the protection frame 6.1 is in a U-shaped opening shape, and its opening faces the other side in the width direction of the conveyor belt of the main conveying component 1. The protection frame 6.1 is used to frame the washing machine conveyed by the main conveying component 1 to the place where the protection frame 6.1 is located. To assist the second clamping component 7 in clamping the washing machine on the main conveying component 1, and does not affect the operation of the washing machine on the main conveying component 1 to this place and does not affect the second clamping component 7 in clamping the washing machine here. Among them, in the protection component 6, the protection driving member serves as a power driving member, which is used to drive the protection frame 6.1 close to the middle of the main conveying component 1 so that the protection frame 6.1 frames and protects the washing machine, and when it is not necessary to frame or avoid interfering with the transportation of the washing machine, it drives the protection frame 6.1 away from the conveying surface of the main conveying component 1 to vacate space to facilitate the transportation of the washing machine and the second clamping component 7 to carry the washing machine. The structure of the protection driving member is various. In this embodiment, the protection driving member includes a protection base 6.2, a protection support rod 6.3, and a protection telescopic member 6.4; the protection base 6.2 is located on one side of the main conveying component 1, and the protection support rod 6.3 is installed thereon. The top of the protection support rod 6.3 extends above the conveyor belt of the main conveying component 1, and the protection telescopic member 6.4 is installed. The protection telescopic member 6.4 is arranged horizontally or vertically. The fixed section of the protection telescopic member 6.4 is installed on the protection support rod 6.3, and the telescopic end installs the protection frame 6.1. Through the telescopic action of the protection telescopic member 6.4, the protection frame 6.1 realizes the protection of the washing machine by means of horizontal movement or vertical up and down movement. Among them, the protection telescopic member 6.4 can be structures such as a cylinder, a hydraulic cylinder, an electric telescopic rod, a linear stepping motor, etc., which are not specifically limited here, and the appendix of the present invention Figure 9 gives one of the ways. Further, in order to avoid damage to the washing machine by the protection frame 6.1 during the protection process, it is preferably provided with a protection layer on the inner U-shaped side wall of the protection frame 6.1, and the protection layer is made of rubber material or sponge material.

[0055] The second clamping assembly 7 is used to clamp the washing machine conveyed to the protection assembly 6. It is located between the main conveying assembly 1 and the outer box installation platform 8 and is arranged opposite to the protection assembly 6. The second clamping assembly 7 has a second clamping part 7.1 for clamping the washing machine framed by the protection frame 6.1, a second clamping driving part 7.2 for driving the second clamping part 7.1 to clamp or release, a claw rotation driving part 7.3 for causing the second clamping part 7.1 to rotate horizontally, and a second clamping sliding driving part 7.4 for causing the second clamping part 7.1 to move horizontally. The second clamping part 7.1 slides between the main conveying assembly 1 and the outer box installation platform 8 under the action of the second clamping sliding driving part 7.4 to place the washing machine back and forth between the main conveying assembly 1 and the outer box installation platform 8.

[0056] In the present invention, the second clamping assembly 7 takes into account the space utilization problem and the operation convenience problem, and adopts operations such as rotation and sliding. Regarding the clamping and fixing problem of the washing machine with a protective frame sleeved thereon, please refer to Figure 9, the second clamping part 7.1 of this embodiment adopts an upper and lower clamping fixing method, specifically: the second clamping drive part 7.2 is a telescopic structure, the telescopic direction is vertical, and the fixed end of the second clamping drive part 7.2 is installed on the claw rotation drive part 7.3; the second clamping part 7.1 includes a lower claw plate 7.1.2 and an upper claw plate 7.1.1 facing each other up and down, the lower claw plate 7.1.2 is located above the conveyor belt of the main conveying assembly 1, and one end of the lower claw plate 7.1.1 is installed on the fixed section of the second clamping drive part 7.2; one end of the upper claw plate 7.1.1 is fixed to the telescopic end of the second clamping drive part 7.2; the distance between the other end of the upper claw plate 7.1.1 and the second clamping drive part 7.2 is greater than the distance between the other end of the lower claw plate 7.1.2 and the second clamping drive part 7.2; the lower claw plate 7.1.2 of this embodiment is fixed, and the upper claw plate 7.1.1 2, so that after the lower claw plate 7.1.2 extends into the bottom of the washing machine, the upper claw plate 7.1.2 and the lower claw plate 7.1.2 can be fixed together to fix the washing machine. In order to match the upper and lower clamping mode of the second clamping part 7.1, preferably, the protective telescopic part 6.4 in the protective assembly 6 is arranged horizontally, and its telescopic direction is horizontal. In this way, after the second clamping part 7.1 clamps the washing machine, it can retract horizontally away from the washing machine, making it convenient for the second clamping part 7.1 to move the washing machine.

[0057] In the present invention, the second clamping part 7.1 moves the washing machine by sliding away from the protective component 6 and the main conveying component 1, and rotates the washing machine from one side of the main conveying component 1 to the side of the installation platform. In this embodiment, it is preferred that the claw rotation drive part 7.3 is installed on the second clamping sliding drive part 7.4, which includes a claw rotation drive motor 7.3.1 and a claw rotation drive platform 7.3.2. The claw rotation drive motor 7.3.1 is installed on the second clamping sliding drive part 7.4, and its output shaft is connected to the claw rotation drive platform 7.3.2. The transmission connection method can be as follows: Figure 9The gear connection method shown can also be a transmission method such as a transmission chain or a transmission belt. The claw rotation drive table 7.3.2 is rotatably installed on the second clamping sliding drive part 7.4, and the rotation axis is vertically arranged. The second clamping drive part 7.2 is installed on the claw rotation drive table 7.3.2, and the second clamping drive part 7.2 and the second clamping part 7.1 rotate together with the claw rotation table. Preferably, the second clamping sliding drive part 7.4 includes a second clamping sliding base, a second clamping sliding drive member, and a second clamping sliding slider; the second clamping sliding base is located on one side of the conveyor belt of the main conveying assembly 1, and the second clamping sliding drive member and the second clamping sliding slider are installed thereon. The drive part of the second clamping sliding drive member is connected to the second clamping sliding slider, and it drives the second clamping sliding slider to slide on the second clamping sliding base. The claw rotation drive part 7.3 is installed on the second clamping sliding slider; the second clamping sliding drive member can be a telescopic structure (such as a cylinder, a hydraulic cylinder, an electric push rod, etc.), or a linear stepping motor structure, or a motor-screw assembly, as shown in the appendix of the present invention Figure 9 as shown.

[0058] In the present invention, the outer box installation platform 8 is used to place the washing machine to be boxed, so as to facilitate the installation and gluing and sealing operations of the washing machine box. Please refer to Figure 10In this embodiment, the outer box mounting platform 8 includes a mounting base, an intermediate mounting platform 8.1, an outer mounting platform 8.2, an intermediate mounting telescopic member and an outer mounting telescopic member. The intermediate mounting platform 8.1 is movably mounted above the mounting base through the intermediate mounting telescopic member. The outer mounting platform 8.2 is framed in the circumference of the intermediate mounting platform 8.1 and is movably mounted above the mounting base through the outer mounting telescopic member. That is, the mounting platform is divided into two independent parts, a middle part and an outer part. The middle part is the intermediate mounting platform 8.1, and the outer part is the outer mounting platform 8.2. The two parts are lifted up and down by the telescopic members connected to each other. By means of independent lifting, the installation platform can be divided into two independently supported parts, and the two parts can support the washing machine at the same time or separately. In this way, when the casing is installed, the peripheral platform 8.2 is installed and lowered, and only the middle platform 8.1 is installed for support. After the casing is installed, its bottom can be lower than the bottom of the washing machine and supported on the peripheral platform 8.2. The box cover 11.5.5 on the top of the casing will be propped open by the washing machine without being mixed, which is convenient for the subsequent operation of the box cover 11.5.5 sealing assembly 11. When gluing is required, the peripheral platform 8.2 is installed and raised to cause the bottom of the casing to be flush with the bottom of the washing machine, thereby facilitating the closing of the box cover 11.5.5. In other words, the installation platform of the present invention can cooperate with the box cover 11.5.5 sealing assembly 11 to better gluing. Preferably, the size of the middle platform 8.1 is smaller than the bottom size of the washing machine, so that the peripheral platform 8.2 can also touch the bottom of the washing machine, and it supports the washing machine together with the middle platform 8.1. The peripheral mounting platform 8.2 is an annular structure, mounted on the mounting base via at least two spaced-apart telescopic mounting members. In this embodiment, the specific structural form of the intermediate telescopic mounting member and the peripheral telescopic mounting member is not limited; they may be pneumatic cylinders, hydraulic cylinders, electric lift rods, or other structures capable of raising and lowering the platform.

[0059] The box placement platform 9 is arranged on one side of the outer box installation platform 8, which is not the side where the second clamping assembly 7 is located. The box placement platform 9 is used to place the box-shaped outer box to be used. Preferably, refer to Figure 10 To facilitate the installation of the outer box, a box placement lifting member is provided at the bottom of the box placement platform 9 to lift the outer box or lower it to facilitate the workers to place the outer box. To facilitate the unfolding of the outer box from the folded state, an unfolding limit platform is provided on the surface of the box placement platform 9. By placing the box frame outside the unfolding limit platform, the outer box is in the unfolded state and can stand upright on the box placement platform 9.

[0060] The box body mounting assembly 10 is arranged on one side of the outer box mounting platform 8 and the box body placing platform 9, and it has a mounting clamping part 10.1 for clamping the outer box, a clamping driving part 10.2 for driving the mounting clamping part 10.1 to grab or release, a clamping lifting part 10.3 for promoting the lifting of the mounting clamping part 10.1, and a clamping sliding driving part 10.4 for promoting the horizontal movement of the mounting clamping part 10.1; the mounting clamping part 10.1 moves back and forth between the outer box mounting platform 8 and the box body placing platform 9 under the action of the clamping sliding driving part 10.4, so as to clamp the outer box on the box body placing platform 9 onto the outer box mounting platform 8, and sleeved the outer box onto the washing machine from the top of the washing machine downwards. After sleeving, it can also be separated from the washing machine, which is convenient for the second clamping assembly 7 to clamp and move the packaged washing machine to the main conveying assembly 1. In this embodiment, the mounting clamping part 10.1 is two clamping plates, the two clamping plates face each other in the horizontal direction, and both are installed on the clamping driving part 10.2, and the clamping driving part 10.2 drives the two clamping plates to move towards each other to clamp and fix or move away from each other to release the clamping; the clamping driving part 10.2 is installed on the clamping lifting part 10.3, and the clamping lifting part 10.3 is installed on the clamping sliding driving part 10.4; in this way, the mounting clamping part 10.1 can clamp from the left and right sides instead of the upper and lower sides. Preferably, the box body mounting assembly 10 and the second clamping assembly 7 are arranged on opposite sides of the mounting platform, and the mounting clamping part 10.1 of the box body mounting assembly 10 and the second clamping part 7.1 are arranged on opposite sides of the outer box mounting platform 8. In this way, the mounting clamping part 10.1 can also be used as a guardrail, which is convenient for the second clamping part 7.1 to push the packed washing machine to tilt and clamp and fix the washing machine based on this. That is to say, the box body mounting assembly 10 can also cooperate with the second clamping assembly 7 to clamp and fix the washing machine. In the present invention, the structure of the clamping driving part 10.2 is various, and it can be a structure such as a cylinder, a hydraulic cylinder, a motor-screw rod, etc., which is not specifically limited here. Similarly, the specific structure of the clamping lifting part 10.3 can also be a cylinder, a hydraulic cylinder, an electric push rod, a linear stepping motor, a scissor structure, etc.; and the same is true for the clamping sliding driving part 10.4, and its specific structure is not limited either. It can be the same as the structure of the second clamping sliding driving part, and Figure 10 is only one of the forms.

[0061] The box cover 11.5.5 sealing glue assembly 11 is arranged on one side of the outer box mounting platform 8, and this side is not the side where the second clamping assembly 7 and the box body placing platform 9 are located. The box cover 11.5.5 sealing glue assembly 11 is used to push the box cover 11.5.5 of the outer box to be adhesively closed, so as to perform sealing operations such as covering, gluing, and pressing the box cover 11.5.5 of the outer box through the box cover 11.5.5 sealing assembly. Specifically, please refer to Figures 11 - 15。In this embodiment, the sealing glue assembly 11 of the box cover 11.5.5 is specifically:

[0062] The glue-sealing assembly 11 of the box cover 11.5.5 includes a glue-applying rotary driving part 11.1, a glue-applying platform 11.2, and a first set of gland assemblies, a second set of gland assemblies, and two sets of glue-applying assemblies 11.5 mounted on the glue-applying platform 11.2; the top driving end of the glue-applying rotary driving part 11.1 is mounted with the glue-applying platform 11.2, which is used to make the glue-applying platform 11.2 located outside the outer box installation platform 8 or directly above the tabletop of the outer box installation platform 8; the first gland assembly 11.3 includes two first pressing rods 11.3.1, a first gland lifting part 11.4.2, and a first gland sliding part 11.3.3. One first pressing rod 11.3.1 is mounted on the driving part of a first gland lifting part 11.4.2 and is mounted on the first gland sliding part 11.3.3 through the first gland lifting part 11.4.2. The first gland sliding part 11.3.3 is mounted on the glue-applying platform 11.2, which drives the first pressing rod 11.3.1 to slide along the width or thickness direction of the outer box. The sliding directions of the two first pressing rods 11.3.1 are opposite to each other. Both are located directly below the glue-applying platform 11.2 and are lifted and lowered in the vertical direction through the first gland lifting part 11.4.2, which is used to open and close a set of box covers 11.5.5 of the outer box; the second gland assembly 11.4 includes at least one set of second pressing parts, a second gland lifting part 11.4.2, and a second gland sliding part 11.4.3. Each set of second pressing parts includes two second pressing rods 11.4.1. One second pressing rod 11.4.1 is mounted on the driving part of a second gland lifting part 11.4.2 and is mounted on the second gland sliding part 11.4.3 through the second gland lifting part 11.4.2. The second gland sliding part 11.4.3 is mounted on the glue-applying platform 11.2, which drives the second pressing rod 11.4.1 to slide on the glue-applying platform 11.2. The sliding direction is perpendicular to the sliding direction of the first pressing rod 11.3.1. The sliding directions of the two second pressing rods 11.4.1 are opposite to each other. Both are located directly below the glue-applying platform 11.2 and are lifted and lowered in the vertical direction through the second gland lifting part 11.4.2, which is used to open and close another set of box covers 11.5.5 of the outer box; the two sets of glue-applying assemblies 11.5 are respectively arranged on the opposite sides of the sliding track line of the second pressing rod 11.4.1. The connection line of the opposite sides is perpendicular to the sliding track line of the second pressing rod 11.4.1. Each set of glue-applying assemblies 11.5 includes a glue tank 11.5.1, a glue-applying pushing part, and a glue-applying sliding part 11.5.2. The glue tank 11.5.1 is used to hold glue, and its bottom is a glue nozzle 11.5.4. An opening and closing driving part for driving its opening and closing is provided at the glue nozzle 11.5.4. The top of the glue tank 11.5.1 is slidably mounted on the glue-applying platform 11.2 through the glue-applying sliding part 11.5.2, and the sliding direction is perpendicular to the sliding direction of the first pressing rod 11.3.1. A glue-applying pushing part for pushing the glue inside it out is mounted on the glue tank 11.5.1.

[0063] Through the above structural settings, sealing operations such as gluing and capping the lid 11.5.5 of the outer box can be achieved. The operating principle is that after the outer box is sleeved on the washing machine on the outer box installation platform 8, the lid 11.5.5 is in a certain open state. The first pressing rod 11.3.1 of the first set of capping components and the second pressing rod 11.4.1 of the second set of capping components are both in the middle of the gluing platform 11.2, that is, in a closed state. In this way, when the gluing platform 11.2 moves to directly above the outer box installation platform 8 under the action of the gluing rotation driving part 11.1, the first pressing rod 11.3.1 and the second pressing rod 11.4.1 are at the middle position of the top of the box body. Under the action of the corresponding lifting part, they descend to fit the top of the washing machine, and then move outward to the left and right under the action of the corresponding capping sliding part. The pressing rod can push the lid 11.5.5 to turn outward by pressing against the lid 11.5.5. After the four-side lids 11.5.5 are all turned outward, the first pressing rod 11.3.1 continues to move outward until it disengages from the lid 11.5.5, and then descends to below the lid 11.5.5, and then moves to fit the outer wall of the box body. After moving upward, it can push the lid 11.5.5 to turn to a vertical state. When the first pressing rod 11.3.1 moves to be flush with the top of the box body, the first pressing rod 11.3.1 moves toward the middle under the action of the first capping sliding part 11.3.3, and can push the lid 11.5.5 on this side to cover the box body. After the lid 11.5.5 on this side is completely covered (i.e., fitted) to the top protective cover of the washing machine, the first pressing rod 11.3.1 stops moving. At this time, the lid 11.5.5 on this side is pressed by the first pressing rod 11.3.1; the glue tank 11.5.1 of the gluing assembly 11.5 is located directly above the lid 11.5.5 pressed by the first pressing rod 11.3.1. The glue nozzle 11.5.4 of the glue tank 11.5.1 is opened under the action of the opening and closing driving part. The glue pushing part operates to extrude the glue in the glue tank 11.5.1 from the glue nozzle 11.5.4. At the same time, the glue tank 11.5.1 slides along the direction perpendicular to the sliding direction of the first pressing rod 11.3.1 under the action of the gluing sliding part 11.5.2, and the glue drops on the lid 11.5.5 and extends from one end of the lid 11.5.5 to the other end. After that, the opening and closing driving part causes the glue nozzle 11.5.4 to close, and the gluing ends; the second pressing rod 11.4.1 and the first pressing rod 11.3.1 drive the lid 11.5.5 to turn and cover the box body in the same way, so that the lid 11.5.5 on this side covers the lid 11.5.5 contacted by the first pressing rod 11.3.1. During the process of the lid 11.5.5 pushed by the second pressing rod 11.4.1 moving toward the middle of the top of the box body to cover, the lid 11.5.5 pressed by the first pressing rod 11.When the cover is continued, it can be directly placed on the box cover 11.5.5 below it. The upper and lower cover 11.5.5 are glued together. The second pressure rod 11.4.1 can press the box cover 11.5.5 it pushes, making the box cover 11.5.5 more adhered. After a period of time, the second pressure rod 11.4.1 rises and separates from the box cover 11.5.5. The gluing platform 11.2 is rotated away from the box body by means of the gluing rotary drive unit 11.1. The second clamping assembly 7 can clamp the packed washing machine. At this time, the upper claw plate 7.1.1 of the second clamping part 7.1 can further press the box cover 11.5.5 during the clamping process, making the gluing effect better. During the entire gluing process described above, the clamping drive unit 10.2 of the box body mounting assembly 10 can be continuously framed around the box body on the outer box mounting platform 8 to protect the washing machine on the outer box mounting platform 8 and facilitate the subsequent clamping of the washing machine by the second clamping assembly 7 after the gluing is completed. It should be noted that when the second clamping portion 7.1 clamps the washing machine on the outer box mounting platform 8, it can slide away from the clamping drive portion 10.2 of the box mounting assembly 10. The washing machine can be separated from the clamping drive portion 10.2 by moving the clamping drive portion 10.2 upward. There are various forms and they are not specifically limited here.

[0064] See also Figures 10 - 11 In this embodiment, the gluing rotary drive unit 11.1 includes a gluing rotary base, a gluing rotary drive motor, and a gluing rotary table. The gluing rotary base is located on one side of the outer box mounting platform 8, on which the gluing rotary drive motor is mounted. The output shaft of the gluing rotary drive motor is in transmission connection with the gluing rotary table. The gluing rotary table is rotatably mounted on the gluing rotary base, with the rotation axis arranged vertically. The gluing platform 11.2 is mounted on the gluing rotary table. The gluing platform 11.2 is movably mounted above the gluing rotary drive unit 11.1 via a gluing lifting support 11.6. The lifting direction of the gluing lifting support 11.6 is vertical, so that the lifting action of the gluing lifting support 11.6 can move the gluing platform 11.2 closer to the top of the washing machine or away from the washing machine, thereby facilitating the gluing platform 11.2 to rotate away from or closer to the washing machine. The first pressure rod 11.3.1 and the second pressure rod 11.4.1 are both L-shaped structures, and the L-shaped short sides of the two first pressure rods 11.3.1 are opposite to each other, and their sliding trajectory lines are located in the middle of the sliding trajectory lines of each group of second pressure pieces; the L-shaped short sides of the two second pressure rods 11.4.1 of each group of second pressure pieces are opposite to each other, so as to better press the box cover 11.5.5 through the L-shaped short sides.

[0065] In the present invention, the glue box 11.5.1 is used to place glue. For the specific structure, please refer to Figures 12 - 14, specifically: the upper end of the glue box 11.5.1 is mounted on the upper glue sliding part 11.5.2, and the lower end is provided with a glue outlet, and the lower end is rotatably mounted with a box cover 11.5.5 plate, and the rotation axis is spaced apart from the glue outlet, and a through hole is provided on the box cover 11.5.5 plate, and the through hole is connected to the glue outlet or staggered with the glue outlet when the glue box 11.5.1 rotates; the glue nozzle 11.5.4 is mounted on the box cover 11.5.5 plate, and its upper end is connected with the through hole; the opening and closing drive unit is an opening and closing rotary motor 11.5.6, which is mounted on the glue box 11.5.1, and its output shaft is transmission connected to the box cover 11.5.5 plate, and the transmission connection method can be a gear set, a transmission chain, a transmission belt or other transmission methods. In the embodiment, the nozzle 11.5.4 is opened and closed by rotating and dislocating, which is convenient for opening and closing.

[0066] In the present invention, the glue extrusion in the glue box 11.5.1 is achieved by using a glue pusher. Below is a form of the glue pusher, specifically:

[0067] The gluing pushing part includes a piston 11.5.7, a driving airbag 11.5.3 and an air source device. The piston 11.5.7 and the driving airbag 11.5.3 are both movably arranged in the glue box 11.5.1. The driving airbag 11.5.3 is arranged between the piston 11.5.7 and the top of the glue box 11.5.1, and is connected to the air source device through an air pipe. The air source device is arranged on the outside of the glue box 11.5.1 and is installed on the gluing platform 11.2; a glue injection port is provided at one end of the glue box 11.5.1 close to the glue nozzle 11.5.4, and the glue injection port is sealed by a valve.

[0068] The air source device inflates and pushes piston 11.5.7, allowing the glue between piston 11.5.7 and nozzle 11.5.4 to be squeezed out of glue box 11.5.1, thereby achieving gluing. After the glue in glue box 11.5.1 is used up, glue can be injected into the glue box 11.5.1 through the glue injection port. During injection, driving airbag 11.5.3 is in a deflated state. In this way, the injected glue can push piston 11.5.7 to reversely squeeze driving airbag 11.5.3. Driving airbag 11.5.3 can be deflated by the air source device or squeezed and deflated during the reverse extrusion process of piston 11.5.7. To achieve deflation during the reverse extrusion process, a three-way valve is provided on the air pipe connecting driving airbag 11.5.3 to the air source device. By controlling the passage of the three-way valve, driving airbag 11.5.3 can be forced into either the inflation passage state or the deflation passage state.
