[0018] Beneficial effects of the present invention:

[0019] 1. When the stacked sheet bodies enter the stage of waiting for packaging, the right lifting plate drives multiple right conveying rollers to move upward, and the height position of the left conveying roller remains unchanged. In this process, multiple right conveying rollers lift the stacked sheet bodies upward for a distance. At this time, there is a gap between the sheet body and the left conveying roller. Then the rotary film wrapping component starts to work and wraps the packaging film around the side wall of the sheet body. Due to the gap between the sheet body and the left conveying roller, when the packaging film is wrapped around this side of the sheet body, the middle section of the packaging film in a vertical state is flush with the side wall of the sheet body at the bottom.

When the packaging film fits the side wall of the sheet body , and the side wall of the sheet body at the bottom can also be fully protected. When the rotary film wrapping assembly is wound to the other side of the sheet body, the right lifting plate drives the multiple right conveying rollers to move downward until the lower end surface of the sheet body contacts the left conveying roller again, and then the left lifting plate drives the multiple left conveying rollers to move upward, and the sheet body is only supported by the multiple left conveying rollers, and the stacked sheet bodies are lifted up for a distance, and then the rotary film wrapping assembly continues to rotate to attach the packaging film to the other side of the sheet body, so that the packaging film will not be hindered by the sheet body and the left conveying roller when it is wrapped around the sheet body, so that the packaging film can be better attached to and wrapped on the side wall of the sheet body.

[0020] 2. When the packaging film starts to be wrapped, the air pump and the air guide cylinder start to work, generating heated air, which is discharged from the end of the blowing pipe through the ventilation hose, and then the hot air will blow on the surface of the packaging film, so that the packaging film can be better attached to the side wall of the sheet body. When the packaging film is wrapped around the sheet body at the bottom, the packaging film extending downward is attached to the lower end surface of the sheet body under the action of the hot air, thereby achieving a better covering effect for the sheet body at the bottom.

[0021] 3. When in use, the ventilation hose has a sufficient length, and the middle section of the ventilation hose is located inside the container, so that when the connecting arm rotates with the rotating arm, the ventilation hose inside the container will not be thrown out, avoiding affecting the packaging operation of the board body.

[0036] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0037] Reference Figure 1-Figure 13 , an automated packaging equipment for PVC wood-plastic boards, comprising a loading and conveying frame 1 and a unloading and conveying frame 2, the upper end surfaces of the loading and conveying frame 1 and the unloading and conveying frame 2 are both rotatably provided with a plurality of planar conveying rollers 3, a fixed base 4 is placed between the loading and conveying frame 1 and the unloading and conveying frame 2, a lifting seat 5 is movably provided on the upper end surface of the fixed base 4, a left lifting plate 6 and a right lifting plate 7 are movably provided above the lifting seat 5, a plurality of left conveying rollers 8 are provided above the left lifting plate 6, a plurality of right conveying rollers 9 are provided above the right lifting plate 7, a rotary film wrapping assembly is provided between the loading and conveying frame 1 and the unloading and conveying frame 2, a driving assembly 1 used in conjunction with the planar conveying roller 3 is provided on the loading and conveying frame 1 and the unloading and conveying frame 2, and a driving assembly 1 for realizing the rotation of the planar conveying roller 3 is a prior art.

[0038] The rotary film wrapping assembly covers the stacked plate bodies 36 with film for protection from bottom to top.

[0039] When in use, the stacked sheet bodies 36 to be packaged are transported by the loading conveyor frame 1 and the flat conveyor roller 3 to the upper surfaces of the right conveyor roller 9 and the left conveyor roller 8. At this time, the sheet body 36 is stationary, and the weight of the sheet body 36 is borne by multiple right conveyor rollers 9 and multiple left conveyor rollers 8. Then the lifting seat 5 drives the right lifting plate 7, the left lifting plate 6, multiple right conveyor rollers 9, and multiple left conveyor rollers 8 to move upward, and lift the stacked sheet bodies 36 upward for a distance, so that the level of the lower end surface of the sheet body 36 is higher than the flat conveyor roller 3, so as to avoid affecting the operation of the rotary film wrapping assembly.

[0040] When the stacked sheet bodies 36 enter the stage of being packaged, refer to Fig.10 and Fig.11 , the right lifting plate 7 drives the multiple right conveying rollers 9 to move upward, and the height position of the left conveying roller 8 remains unchanged. In this process, the multiple right conveying rollers 9 lift the stacked sheet bodies 36 upward for a distance. At this time, there is a gap between the sheet body 36 and the left conveying roller 8. Then the rotary film wrapping assembly starts to work and wraps the packaging film around the side wall of the sheet body 36. Due to the gap between the sheet body 36 and the left conveying roller 8, when the packaging film is wrapped around this side of the sheet body 36, the middle section of the packaging film in a vertical state is flush with the side wall of the sheet body 36 at the bottom (the lower end of the packaging film at the bottom extends downward for a distance). Then the rotary film wrapping assembly starts to rotate and wrap the packaging film. When the packaging film is attached to the side wall of the sheet body 36, the side wall of the sheet body 36 at the bottom can also be fully protected. When the rotary film wrapping assembly is wrapped around the other side of the sheet body 36, refer to Fig.12 and Fig.13 At this time, the right lifting plate 7 drives the multiple right conveying rollers 9 to move downward until the lower end surface of the sheet body 36 contacts the left conveying roller 8 again, and then the left lifting plate 6 drives the multiple left conveying rollers 8 to move upward, and only the sheet body 36 is supported by the multiple left conveying rollers 8, and the stacked sheet bodies 36 are lifted up by one end, and then the rotary film wrapping assembly continues to rotate to attach the packaging film to the other side of the sheet body 36, so that the packaging film will not be hindered by the sheet body 36 and the left conveying roller 8 when it is wrapped around the sheet body 36, so that the packaging film can be better attached to and wrapped on the side wall of the sheet body 36.

[0041] When the packaging film has finished covering the sheet body 36 at the bottom, the left lifting plate 6 drives the left conveying roller 8 to move downward until the lower end surface of the sheet body 36 contacts the right conveying roller 9 and the left conveying roller 8 again.

[0042] A lifting groove 10 is formed on the upper end surface of the fixed base 4 , and the lifting seat 5 is movably arranged in the lifting groove 10 . A plurality of hydraulic rods 11 are fixed between the inner bottom of the lifting groove 10 and the lifting seat 5 .

[0043] In the initial state, the telescopic end of the hydraulic rod 11 is in a retracted state, causing the right conveying roller 9 and the left conveying roller 8 to be flush with the upper surface of the flat conveying roller 3, so that the sheet body 36 can be moved and conveyed to the upper surface of the right conveying roller 9 and the left conveying roller 8, and then the telescopic end of the hydraulic rod 11 extends, pushing the lifting seat 5 to drive the right lifting plate 7, the left lifting plate 6, multiple right conveying rollers 9, and multiple left conveying rollers 8 to move upward, and lift the stacked sheet bodies 36 upward for a distance to cooperate with the film wrapping operation.

[0044] A plurality of hydraulic rods 12 are fixed between the lifting seat 5 and the right lifting plate 7. A plurality of pairs of connecting blocks 13 are fixed to the upper end surface of the right lifting plate 7. A U-shaped frame 14 is fixed to the upper end surface of each connecting block 13. Each right conveying roller 9 is rotatably arranged in the corresponding U-shaped frame 14. A driving component 2 for driving the right conveying roller 9 is arranged on one side of the plurality of U-shaped frames 14. The driving component 2 for driving the right conveying roller 9 to rotate is the prior art. Some connecting blocks 13 movably penetrate the left lifting plate 6.

[0045] In the initial state, the telescopic end of the hydraulic rod 12 is in a retracted state. When multiple right-side conveying rollers 9 are needed to lift the sheet body 36, the telescopic ends of the multiple hydraulic rods 12 are extended, thereby pushing the right-side lifting plate 7, the connecting block 13 and the U-shaped frame 14 to move upward, thereby lifting the sheet body 36 for a distance to cooperate with the winding of the packaging film.

[0046] A pad 15 is fixed to the upper end surface of the lifting seat 5, and a plurality of hydraulic rods three 16 are fixed to the upper end surface of the pad 15, each of the hydraulic rods three 16 is movable and penetrates the right lifting plate 7, and the end of the telescopic end of each hydraulic rod three 16 is fixedly connected to the bottom of the left lifting plate 6, and a plurality of pairs of connecting blocks two 17 are fixed to the upper end surface of the left lifting plate 6, and a U-shaped frame two 18 is fixed to the upper end surface of each pair of connecting blocks two 17, and each left conveying roller 8 is rotatably set in the corresponding U-shaped frame two 18, and a driving component three used in conjunction with the left conveying roller 8 is set on one side of the plurality of U-shaped frames two 18, and the driving component three used to drive the left conveying roller 8 to rotate is the prior art.

[0047] A plurality of guide posts 19 are fixed to the lower end surface of the left lifting plate 6 . Each guide post 19 movably penetrates the right lifting plate 7 . The lower end of each guide post 19 movably penetrates into the lifting seat 5 .

[0048] The rotary film wrapping assembly includes two support frames 20, a top mounting plate 21 is fixed between the two support frames 20, a rotating arm 22 is rotatably provided on the lower end surface of the top mounting plate 21, a connecting arm 23 is fixed on the lower end surface of one end of the rotating arm 22, a U-shaped frame 24 is movably provided on one side of the connecting arm 23, a film reel 25 is rotatably provided inside the U-shaped frame 24, and the rotary film wrapping assembly also includes an auxiliary positioning unit and a cutting unit, and these partial structures are all prior arts.

[0049] First, the auxiliary positioning unit cooperates with the film roll 25 to attach one end of the packaging film to one side of the plate body 36, and then the rotating arm 22 drives the connecting arm 23 to rotate. During the rotation, the connecting arm 23 cooperates with the film roll 25 to wind the packaging film on the side wall of the stacked plate body 36. When the packaging film is wound and packaged, the right conveying roller 9 and the left conveying roller 8 move downward to a state flush with the plane conveying roller 3, and then under the action of the right conveying roller 9, the left conveying roller 8 and the plane conveying roller 3, the stacked plate bodies 36 are unloaded and conveyed, and then under the action of the cutting unit, the packaging film on the film roll 25 is cut. This part of the structure is all prior art.

[0050] An air pump 26 and an air cylinder 27 are fixed to one side of the connecting arm 23, an air heating wire is fixed to the inner wall of the air cylinder 27, an air outlet end of the air pump 26 is connected with one end of the air cylinder 27, a mounting block 28 is fixed to the lower end surface of the U-shaped frame 24, an air blowing pipe 29 is fixedly provided through the side wall of the mounting block 28, an air inlet end of the air blowing pipe 29 is connected with the other end of the air cylinder 27 and a ventilation hose 30 is provided.

[0051] When the packaging film starts to be wrapped, the air pump 26 and the air guide cylinder 27 start to work, generating heated air, which is discharged from the end of the blowing pipe 29 through the ventilation hose 30, and then the hot air will blow on the surface of the packaging film, so that the packaging film can be better attached to the side wall of the sheet body 36. When the packaging film is wrapped around the sheet body 36 located at the bottom, the packaging film extending downward is attached to the lower end surface of the sheet body 36 under the action of the hot air, thereby achieving a better wrapping effect for the sheet body 36 located at the bottom.

[0052] A connecting column 31 is fixed to the lower end of the connecting arm 23 , a containing barrel 32 is provided below the connecting arm 23 , the lower end of the connecting column 31 is fixedly connected to the inner bottom of the containing barrel 32 , and the middle section of the ventilation hose 30 is placed in the containing barrel 32 .

[0053] When in use, the ventilation hose 30 has a sufficient length, and the middle section of the ventilation hose 30 is located inside the container 32, so that when the connecting arm 23 rotates following the rotating arm 22, the ventilation hose 30 inside the container 32 will not be thrown out, thereby avoiding affecting the packaging operation of the plate body 36.

[0054] An electric push rod 33 is fixed to the lower end surface of the rotating arm 22 , a connecting plate 34 is fixed to the end of the telescopic end of the electric push rod 33 , and a contact plate 37 is rotatably provided on the lower end surface of the connecting plate 34 .

[0055] When the packaging film has finished wrapping the sheet body 36 at the bottom, the multiple right conveying rollers 9 and the multiple left conveying rollers 8 again bear the weight of the sheet body 36. At this time, the telescopic end of the electric push rod 33 extends, pushing the connecting plate 34 and the contact plate 37 to move downward until the contact plate 37 contacts the upper end surface of the sheet body 36 at the top, thereby applying a downward force to the stacked sheet bodies 36 to prevent the packaging film from causing displacement of the sheet body 36 at the upper part when it is wrapped around the sheet body 36, thereby affecting the packaging effect.

[0056] A T-shaped connecting ring 35 is fixed to the upper end surface of the abutment plate 37 , and a T-shaped ring groove for matching with the T-shaped connecting ring 35 is formed on the lower end surface of the connecting plate 34 , and the T-shaped connecting ring 35 is rotatably disposed in the T-shaped ring groove.

[0057] When the rotating arm 22 drives the connecting arm 23 to rotate and cooperates with the packaging film winding work, the rotating arm 22 will also drive the electric push rod 33 and the connecting disk 34 to rotate. Through the cooperation of the set T-shaped connecting ring 35 and the T-shaped ring groove, the electric push rod 33 and the connecting disk 34 will not affect the use of the interference disk 37 during the rotation process.

[0058] When the present invention is in use, the stacked sheet bodies 36 to be packaged are transported by the feeding conveyor frame 1 and the flat conveyor roller 3 to the upper surface of the right conveyor roller 9 and the left conveyor roller 8. At this time, the sheet bodies 36 are stationary, and the weight of the sheet bodies 36 is borne by the plurality of right conveyor rollers 9 and the plurality of left conveyor rollers 8. Then, the lifting seat 5 drives the right lifting plate 7, the left lifting plate 6, the plurality of right conveyor rollers 9, and the plurality of left conveyor rollers 8 to move upward, and the stacked sheet bodies 36 are lifted up for a distance, so that the level of the lower end surface of the sheet bodies 36 is higher than the flat conveyor roller 3, so as to avoid affecting the operation of the rotary film wrapping assembly.

[0059] First, the auxiliary positioning unit cooperates with the film roll 25 to attach one end of the packaging film to one side of the sheet body 36, and then the rotating arm 22 drives the connecting arm 23 to rotate. During the rotation process, the connecting arm 23 cooperates with the film roll 25 to roll the packaging film on the side wall of the stacked sheet body 36. When the packaging film is rolled and packaged, the right conveying roller 9 and the left conveying roller 8 move downward to a state flush with the plane conveying roller 3, and then under the action of the right conveying roller 9, the left conveying roller 8 and the plane conveying roller 3, the stacked sheet body 36 is unloaded and conveyed, and then under the action of the cutting unit, the packaging film on the film roll 25 is cut;

[0060] When the stacked sheet bodies 36 enter the stage of being packaged, refer to Fig.10 and Fig.11 , the right lifting plate 7 drives the multiple right conveying rollers 9 to move upward, and the height position of the left conveying roller 8 remains unchanged. In this process, the multiple right conveying rollers 9 lift the stacked sheet bodies 36 upward for a distance. At this time, there is a gap between the sheet body 36 and the left conveying roller 8. Then the rotary film wrapping assembly starts to work and wraps the packaging film around the side wall of the sheet body 36. Due to the gap between the sheet body 36 and the left conveying roller 8, when the packaging film is wrapped around this side of the sheet body 36, the middle section of the packaging film in a vertical state is flush with the side wall of the sheet body 36 at the bottom (the lower end of the packaging film at the bottom extends downward for a distance). Then the rotary film wrapping assembly starts to rotate and wrap the packaging film. When the packaging film is attached to the side wall of the sheet body 36, the side wall of the sheet body 36 at the bottom can also be fully protected. When the rotary film wrapping assembly is wrapped around the other side of the sheet body 36, refer to Fig.12 and Fig.13 At this time, the right lifting plate 7 drives the plurality of right conveying rollers 9 to move downward until the lower end surface of the sheet body 36 contacts the left conveying roller 8 again, and then the left lifting plate 6 drives the plurality of left conveying rollers 8 to move upward, and the sheet body 36 is supported only by the plurality of left conveying rollers 8, and the stacked sheet bodies 36 are lifted up by one end, and then the rotary film wrapping assembly continues to rotate, and the packaging film is attached to the other side of the sheet body 36, so that the packaging film will not be hindered by the sheet body 36 and the left conveying roller 8 when the sheet body 36 is wrapped around. Therefore, the packaging film can be better attached to and wrapped on the side wall of the sheet body 36;

[0061] When the packaging film starts to be wrapped, the air pump 26 and the air guide cylinder 27 start to work, generating heated air, which is discharged from the end of the blowing pipe 29 through the ventilation hose 30, and then the hot air blows on the surface of the packaging film, so that the packaging film is better attached to the side wall of the sheet body 36. When the packaging film is wrapped around the sheet body 36 at the bottom, the packaging film extending downward is attached to the lower end surface of the sheet body 36 under the action of the hot air, so that a better wrapping effect is achieved for the sheet body 36 at the bottom.

[0062] When the packaging film has finished wrapping the sheet body 36 at the bottom, the multiple right conveying rollers 9 and the multiple left conveying rollers 8 again bear the weight of the sheet body 36. At this time, the telescopic end of the electric push rod 33 extends, pushing the connecting plate 34 and the contact plate 37 to move downward until the contact plate 37 contacts the upper end surface of the sheet body 36 at the top, thereby applying a downward force to the stacked sheet bodies 36 to prevent the packaging film from causing displacement of the sheet body 36 at the upper part when it is wrapped around the sheet body 36, thereby affecting the packaging effect.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
