Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of gypsum line and specifically relates to a method and device for vertical film wrapping of gypsum line. BACKGROUND

[0002] Gypsum line is a commonly used decorative component in the field of building decoration, and is widely used in the decoration of the junction of indoor walls and ceilings due to its various shapes and convenient installation. However, gypsum line is brittle and hard, and its surface is easy to break. During transportation and storage after leaving the factory, it needs to be protected by film wrapping. It is necessary to avoid edge and corner breakage caused by external force impact, and to prevent dust and moisture from polluting the surface texture. Therefore, the packaging quality directly affects the product qualification rate and customer experience.

[0003] With the development of large-scale production of gypsum line, the packaging method gradually changes from traditional manual film wrapping to mechanical film wrapping. Among them, vertical film wrapping becomes the mainstream of mechanical packaging because it saves floor space, facilitates subsequent stacking and storage, and reduces the risk of surface deformation caused by pressure when the gypsum line is placed horizontally.

[0004] However, the positioning, lifting, unwinding and winding function modules of the existing vertical film wrapping device are designed independently, and there is a lack of linkage control mechanism between the modules, which leads to a bulky overall structure of the device, large space occupation and is not conducive to the integrated layout of the production line. At the same time, manual intervention is required for action switching between modules, such as manual calibration of the position of the gypsum line after lifting and manual adjustment of the tension before unwinding the film, which not only increases the intensity of manual operation, but also further reduces the stability of packaging quality due to human operation errors.

[0005] Therefore, the present application is proposed. SUMMARY

[0006] To solve the above technical problems, the basic idea of the technical solution of the present application is: A vertical film packaging device for plaster moldings includes a workbench with a placement platform above it.

A positioning plate is positioned above each plaster molding body. Two symmetrical transmission components are also provided above the workbench, each with a first film body and a second film body. A driving component is also provided above the workbench. The driving component drives the first flipping plates to rotate, and when the first flipping plates rotate, they drive the plaster molding bodies to rise. The driving component also drives the positioning plates to press down on the top of the plaster molding bodies.

[0007] In a preferred embodiment of the present invention, the placement platform is provided with two L-shaped mounting blocks in the inner cavities of the two rectangular slots. A second rotating component is provided above each L-shaped mounting block, and the second rotating components are respectively provided on the first flip plate. The two opposite side walls of the inner cavities of the two rectangular slots are provided with first rotating components, and the first rotating components are respectively provided with second flip plates. The ends of the two first flip plates away from the worktable are provided with inclined surfaces.

[0008] In a preferred embodiment of the present invention, support legs are provided around the top of the workbench, the four support legs are symmetrical to each other, a top plate is provided above the four support legs, a positioning component is provided at the bottom of the top plate, the positioning component is used to position the transmission component, a mounting bracket is provided at one end of each pair of the four support legs, a connecting bracket is provided at one end of each pair of the four mounting brackets, and the two connecting brackets are symmetrical to each other.

[0009] In a preferred embodiment of the present invention, the driving assembly includes two hydraulic cylinders, which are respectively disposed at the bottom of the connecting frame. Each of the two hydraulic cylinders has an L-shaped placement plate at its output end. Each of the two L-shaped placement plates has a C-shaped connecting plate on the same side wall. The two C-shaped connecting plates are symmetrical to each other, and each of the two C-shaped connecting plates has a connecting rod.

[0010] In a preferred embodiment of the present invention, a connecting plate is provided above the two connecting rods, a connecting rod is provided at the bottom middle of the connecting plate, and a positioning plate is provided at the end of the connecting rod away from the connecting plate.

[0011] In a preferred embodiment of the present invention, each of the two L-shaped placement plates is provided with a mounting plate at its bottom, the two mounting plates are symmetrical to each other, and each of the two mounting plates is provided with an adhesive plate on both sides, and the adhesive plate is connected to the first film body and the second film body respectively.

[0012] In a preferred embodiment of the present invention, each of the two movable slots is slidably provided with a movable block, the two movable blocks are symmetrical to each other, and a first swing arm and a second swing arm are respectively provided at the bottom of the two movable blocks, the first swing arm and the second swing arm are symmetrical to each other.

[0013] In a preferred embodiment of the present invention, rotating rods are provided on both side walls of the first and second swing arms. Each rotating rod is symmetrical to the other two. A bearing is provided at one end of each rotating rod away from the first and second swing arms. A torsion spring is provided on each rotating rod. The two ends of each torsion spring are respectively provided on the bearing and the side wall opposite to the first and second swing arms.

[0014] In a preferred embodiment of the present invention, the first swing arm and the second swing arm are respectively provided with lifting plates at opposite ends of the inner cavity of the mounting slot, and a plaster line body is provided above the lifting plate. The inner cavity of the mounting slot is also provided with a limiting block, which is located in the middle of the lifting plate.

[0015] A method for vertical film packaging of plaster moldings, comprising the following steps: Step 1: Place multiple plaster molding bodies equidistantly above the lifting plate in the inner cavity of the mounting slot. Activate the two hydraulic cylinders at the bottom of the connecting frame. The output end of the hydraulic cylinders drives the L-shaped placement plate to move. At this time, the adhesive plates on both sides of the mounting plate at the bottom of the L-shaped placement plate will pull the first and second film bodies connected to them. With the assistance of the unwinding of the two transmission components above the worktable, the film bodies are unwound smoothly. At the same time, the C-shaped connecting plate on the side wall of the L-shaped placement plate drives the connecting plate to move through the connecting rod, so that the positioning plate at one end of the connecting rod at the bottom of the connecting plate moves to the top of the plaster molding body and presses and positions the plaster molding body. Step 2: As the hydraulic cylinder continues to drive the L-shaped placement plate to move, when the L-shaped placement plate moves to a specific position, it comes into contact with the inclined surface of the first flip plate away from the worktable and generates compression; since the first flip plate is installed above the L-shaped mounting block in the rectangular slot cavity of the placement table through the second rotating assembly, under the compression of the inclined surface, the first flip plate gradually flips around the second rotating assembly. Step 3: After the first flipping plate flips to a certain angle, it comes into contact with the moving block that is slidably set in the inner cavity of the moving slot of the placement platform, and pushes the moving block to slide down along the moving slot; the first and second swing arms at the bottom of the moving block move down synchronously with the moving block, and rotate with the assistance of the rotating rod, bearing and torsion spring. The ends of the first and second swing arms away from the moving block are lifted up, generating an upward lifting force on the lifting plate, and driving the plaster line body above the lifting plate to move up to the appropriate position required for the film covering. Step 4: After the plaster line body rises to the designated position, the staff controls the second flipping plates on both sides of the rectangular slot inner cavity of the placement platform to flip around the first rotating component; at the same time, the existing pushing equipment is started to push the first film body and the second film body that have been unwound to move in opposite directions, so that the two films are tightly attached and completely wrapped around the side wall of the plaster line body, completing the vertical film wrapping operation of the plaster line body. Step 5: After the film wrapping operation is completed, control the hydraulic cylinder output end to reset, driving the L-shaped placement plate, C-shaped connecting plate, connecting plate, positioning plate and mounting plate and other components back to their initial positions. The first flipping plate, moving block, first swing arm, second swing arm and lifting plate return to their initial state under their own structural reset characteristics or the action of auxiliary components. Then take out the packaged gypsum line body and prepare for the film wrapping of the next batch of gypsum lines.

[0016] Compared with the prior art, the present invention has the following advantages: This invention, through a driving component, can drive the positioning plate to press on the top of the plaster line body, ensuring that the position of the plaster line body is stable and does not shift during film wrapping; it can also drive the first flipping plate to rotate, thereby driving the plaster line body to rise, eliminating the need for an additional lifting structure and simplifying the operation process; at the same time, the symmetrical transmission components on the worktable assist the first film body and the second film body to be smoothly unwound, ultimately making the two films tightly wrapped around the plaster line body, resulting in a compact overall structure that effectively improves film wrapping efficiency and packaging quality.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0021] Example 1: like Figures 1 to 8As shown, a vertical film packaging device for plaster moldings includes a workbench 1, a placement platform 11 above the workbench 1, two rectangular slots 111 symmetrically arranged above the placement platform 11, and mounting slots 113 on the opposite side wall of the placement platform 11 opposite to the rectangular slots 111. Two movable slots 112 symmetrically arranged and L-shaped are also provided on the placement platform 11. Two first flip plates 15 and two second flip plates 152 are also arranged above the placement platform 11, each first flip plate 15 and each second flip plate 152 being symmetrically arranged. The initial state of the flip plate 152 is U-shaped, and the inner cavity contains multiple plaster line bodies 16 that are evenly distributed. Each plaster line body 16 is provided with a positioning plate 222 above it. Two transmission components 131 are also provided above the worktable 1. The two transmission components 131 are symmetrical to each other, and a first film body 132 and a second film body 133 are respectively provided on the two transmission components 131. A drive component is also provided above the worktable 1. The drive component is used to drive the first flip plate 15 to rotate, and when the first flip plate 15 rotates, it is used to drive the plaster line body 16 to rise. The drive component is also used to drive the positioning plate 222 to press the plaster line body 16. The drive assembly can drive the positioning plate 222 to press the plaster line body 16 above, ensuring that the position of the plaster line body 16 is stable and does not shift during film wrapping; it can also drive the first flipping plate 15 to rotate, thereby driving the plaster line body 16 to rise, eliminating the need for an additional lifting structure and simplifying the operation process; at the same time, the symmetrical transmission assembly 131 on the worktable 1 assists the first film body 132 and the second film body 133 to unwind smoothly, ultimately making the two films tightly wrapped around the plaster line body 16. The overall structure is compact, effectively improving film wrapping efficiency and packaging quality.

[0022] like Figures 1 to 6 and Figure 8 As shown, in a specific embodiment, the placement platform 11 has two L-shaped mounting blocks 153 in the inner cavities of the two rectangular slots 111. Each L-shaped mounting block 153 has a second rotating assembly 155 above it, and the second rotating assemblies 155 are respectively mounted on the first flip plates 15. The opposite side walls of the inner cavities of the two rectangular slots 111 are each provided with a first rotating assembly 154, and a second flip plate 152 is respectively mounted on each of the first rotating assemblies 154. The ends of the two first flip plates 15 away from the worktable 1 each have an inclined surface 151. This configuration ensures that the first flip plates 15 and the second flip plates 152 can be flipped.

[0023] like Figures 1 to 6As shown, furthermore, support legs 12 are provided around the top of the workbench 1, with each pair of support legs 12 being symmetrical. A top plate 121 is provided above the four support legs 12, and a positioning component 13 is provided at the bottom of the top plate 121. The positioning component 13 is used to position the transmission component 131. Each pair of opposite ends of the four support legs 12 is provided with a mounting bracket 122, and each pair of opposite ends of the four mounting brackets 122 is provided with a connecting bracket 123, with the two connecting brackets 123 being symmetrical. In this configuration, the installation position of the connecting bracket 123 is determined.

[0024] Example 2: The difference between the above embodiments and this embodiment is that: Figures 1 to 6 As shown, a vertical film-wrapping device for gypsum board molding includes a drive assembly comprising two hydraulic cylinders 2, each mounted at the bottom of a connecting frame 123. Each hydraulic cylinder 2 has an L-shaped placement plate 21 at its output end. A C-shaped connecting plate 211 is mounted on the same side wall of each L-shaped placement plate 211, and the two C-shaped connecting plates 211 are symmetrical to each other. Each C-shaped connecting plate 211 has a connecting rod 212. The installation position of the hydraulic cylinders 21 is determined in this configuration.

[0025] like Figures 1 to 6 As shown, in a specific embodiment, a connecting plate 22 is provided above the two connecting rods 212, a connecting rod 221 is provided at the bottom center of the connecting plate 22, and a positioning plate 222 is provided at the end of the connecting rod 221 away from the connecting plate 22. A mounting plate 23 is provided at the bottom of each of the two L-shaped placement plates 21, and the two mounting plates 23 are symmetrical to each other. Adhesive plates 231 are provided on both sides of each mounting plate 23, and the adhesive plates 231 are respectively connected to the first film body 132 and the second film body 133. In this configuration, the movement of the L-shaped placement plate 21 will drive the adhesive plates 231 to move synchronously, thereby pulling the first film body 132 and the second film body 133 to achieve smooth unwinding with the cooperation of the transmission component 131.

[0026] like Figures 1 to 7As shown, furthermore, each of the two movable slots 112 has a movable block 3 slidably disposed within its inner cavity. The two movable blocks 3 are symmetrical to each other. A first swing arm 31 and a second swing arm 311 are respectively disposed at the bottom of the two movable blocks 3. The first swing arm 31 and the second swing arm 311 are symmetrical to each other. Rotating rods 312 are disposed on both side walls of the first swing arm 31 and the second swing arm 311. Each rotating rod 312 is symmetrical to each other. A bearing 313 is disposed at one end of each rotating rod 312 away from the first swing arm 31 and the second swing arm 311. A torsion spring 314 is disposed on each rotating rod 312. The two ends of each torsion spring 314 are respectively disposed on the bearing 313 and the opposite side wall of the first swing arm 31 and the second swing arm 311. The first swing arm 31 and the second swing arm 311 are respectively provided with lifting plates 32 at opposite ends of the inner cavity of the mounting slot 113, and the plaster line body 16 is provided above the lifting plate 32. The inner cavity of the mounting slot 113 is also provided with a limiting block 33, which is located in the middle of the lifting plate 32. In this configuration, it is ensured that when the first flip plate 15 is flipped to a certain angle, it will contact the moving block 3 that is slidably provided in the inner cavity of the moving slot 112 of the placement platform 11 and push the moving block 3 to move downward along the moving slot 112. The first swing arm 31 and the second swing arm 311 provided at the bottom of the moving block 3 will rotate with the moving block 3 while moving downward, with the assistance of the rotating rod 312 and the bearing 313. The ends of the two arms away from the moving block 3 will rotate upward, thus generating an upward lifting force on the lifting plate 32 placed in the inner cavity of the mounting slot 113, thereby driving the plaster line body 16 above the lifting plate 32 to move upward.

[0027] Example 3: This invention also discloses a method for vertical film packaging of plaster moldings, the steps of which are as follows: Step 1: Place multiple plaster line bodies 16 equidistantly above the lifting plate 32 in the inner cavity of the mounting slot 113. Activate the two hydraulic cylinders 2 at the bottom of the connecting frame 123. The output end of the hydraulic cylinders 2 drives the L-shaped placement plate 21 to move. At this time, the adhesive plates 231 on both sides of the mounting plate 23 at the bottom of the L-shaped placement plate 21 will pull the first film body 132 and the second film body 133 connected to it. With the assistance of the unwinding of the two transmission components 131 above the workbench 1, the film body is unwound smoothly. At the same time, the C-shaped connecting plate 211 on the side wall of the L-shaped placement plate 21 drives the connecting plate 22 to move through the connecting rod 212, so that the positioning plate 222 at one end of the connecting rod 221 at the bottom of the connecting plate 22 moves to the top of the plaster line body 16, pressing and positioning the plaster line body 16. Step 2: As the hydraulic cylinder 2 continues to drive the L-shaped placement plate 21 to move, when the L-shaped placement plate 21 moves to a specific position, it comes into contact with the inclined surface 151 of the first flip plate 15 away from the worktable 1 and generates compression; since the first flip plate 15 is installed above the L-shaped mounting block 153 in the inner cavity of the rectangular slot 111 of the placement table 11 through the second rotating assembly 155, under the compression action of the inclined surface 151, the first flip plate 15 gradually flips around the second rotating assembly 155. Step 3: After the first flip plate 15 flips to a certain angle, it comes into contact with the moving block 3 that is slidably disposed in the inner cavity of the moving slot 112 of the placement platform 11, and pushes the moving block 3 to slide down along the moving slot 112; the first swing arm 31 and the second swing arm 311 at the bottom of the moving block 3 move down synchronously with the moving block 3, and rotate with the assistance of the rotating rod 312, the bearing 313 and the torsion spring 314. The ends of the first swing arm 31 and the second swing arm 311 away from the moving block 3 are lifted up, generating an upward lifting force on the lifting plate 32, and driving the plaster line body 16 above the lifting plate 32 to move up to the appropriate position required for the film covering. Step 4: After the plaster line body 16 rises to the designated position, the staff controls the second flipping plate 152 on both sides of the inner cavity of the rectangular slot 111 of the placement platform 11 to flip around the first rotating component 154; at the same time, the existing pushing equipment is started to push the first film body 132 and the second film body 133, which have been unwound, to move in opposite directions, so that the two films are tightly attached and completely wrapped around the side wall of the plaster line body 16, thus completing the vertical film wrapping operation of the plaster line body 16. Step 5: After the film wrapping operation is completed, control the output end of the hydraulic cylinder 2 to reset, driving the L-shaped placement plate 21, C-shaped connecting plate 211, connecting plate 22, positioning plate 222 and mounting plate 23 back to their initial positions. The first flipping plate 15, moving block 3, first swing arm 31, second swing arm 311 and lifting plate 32 return to their initial state under their own structural reset characteristics or the action of auxiliary components. Then, take out the packaged gypsum line body 16 to prepare for the film wrapping of the next batch of gypsum lines.

[0028] The implementation principle of a vertical film-wrapping device for gypsum lines in this embodiment is as follows: First, the two hydraulic cylinders 2 installed at the bottom of the connecting frame 123 start to operate, and their output ends drive the L-shaped placement plate 21 connected to them to move. On the one hand, since the bottom of the L-shaped placement plate 21 is equipped with symmetrical mounting plates 23, and the adhesive plates 231 on both sides of the mounting plate 23 are connected to the first film body 132 and the second film body 133 respectively, and the two symmetrical transmission components 131 above the worktable 1 provide unwinding assistance for the film, the movement of the L-shaped placement plate 21 will drive the adhesive plates 231 to move synchronously, thereby pulling the first film body 132 and the second film body 133 to achieve smooth unwinding with the cooperation of the transmission components 131; On the other hand, the C-shaped connecting plate 211 connected to the same side wall of the L-shaped placement plate 21 will move together with the L-shaped placement plate 21. The connecting rod 212 on the C-shaped connecting plate 211 will then drive the connecting plate 22 to move. The connecting rod 221 at the bottom middle of the connecting plate 22 will move synchronously, eventually causing the positioning plate 222 at the end of the connecting rod 221 away from the connecting plate 22 to move above the plaster line body 16 placed above the lifting plate 32, thereby pressing and positioning the plaster line body 16 to ensure the stability of the position of the plaster line body 16 during the subsequent film covering process. At the same time, when the L-shaped placement plate 21 moves to a specific position, it will come into contact with the inclined surface 151 of the first flip plate 15 at the end away from the worktable 1 and generate a squeezing effect; since the first flip plate 15 is installed above the L-shaped mounting block 153 in the inner cavity of the rectangular slot 111 of the placement table 11 through the second rotating assembly 155, when the inclined surface 151 is squeezed, the first flip plate 15 will gradually flip around the second rotating assembly 155. As the first flip plate 15 flips to a certain angle, it comes into contact with the movable block 3, which is slidably disposed in the inner cavity of the movable slot 112 of the placement platform 11, and pushes the movable block 3 to move downward along the movable slot 112. The first swing arm 31 and the second swing arm 311 disposed at the bottom of the movable block 3 will rotate with the assistance of the rotating rod 312 and the bearing 313 as the movable block 3 moves downward. The ends of the two arms away from the movable block 3 will rotate upward, thus generating an upward lifting force on the lifting plate 32 placed in the inner cavity of the mounting slot 113, thereby driving the lifting plate to move downward. The plaster line body 16 above the board 32 moves upward; after the plaster line body 16 rises to the appropriate position, the staff controls the second flipping plate 152 to flip around the first rotating component 154 on both sides of the inner cavity of the rectangular slot 111. At the same time, the existing equipment pushes the first film body 132 and the second film body 133, which have been unwound, to move in opposite directions, so that the first film body 132 and the second film body 133 are tightly attached to and wrapped around the side wall of the plaster line body 16, and finally the vertical film wrapping operation of the plaster line body 16 is completed.

The inner cavity of the mounting slot (113) is also provided with a limiting block (33), which is located in the middle of the lifting plate (32).

10. A method for vertical film packaging of plaster moldings, characterized in that, A vertical film-wrapping device for plaster moldings, as described in any one of claims 1 to 9, and a method for vertical film-wrapping plaster moldings, comprising the following steps: Step 1: Place multiple plaster line bodies (16) at equal intervals above the lifting plate (32) in the inner cavity of the mounting slot (113). Start the two hydraulic cylinders (2) at the bottom of the connecting frame (123). The output end of the hydraulic cylinder (2) drives the L-shaped placement plate (21) to move. At this time, the adhesive plates (231) on both sides of the mounting plate (23) at the bottom of the L-shaped placement plate (21) will pull the first film body (132) and the second film body (133) connected to it. With the help of the unwinding of the two transmission components (131) above the workbench (1), the unwinding is achieved smoothly. At the same time, the C-shaped connecting plate (211) on the side wall of the L-shaped placement plate (21) drives the connecting plate (22) to move through the connecting rod (212). This moves the positioning plate (222) at one end of the connecting rod (221) at the bottom of the connecting plate (22) to the top of the plaster line body (16) and presses and positions the plaster line body (16). Step 2: As the hydraulic cylinder (2) continues to drive the L-shaped placement plate (21) to move, when the L-shaped placement plate (21) moves to a specific position, it comes into contact with the inclined surface (151) of the first flip plate (15) away from the worktable (1) and generates compression; since the first flip plate (15) is installed above the L-shaped mounting block (153) in the inner cavity of the rectangular slot (111) of the placement table (11) through the second rotating assembly (155), under the compression of the inclined surface (151), the first flip plate (15) gradually flips around the second rotating assembly (155). Step 3: After the first flip plate (15) flips to a certain angle, it comes into contact with the moving block (3) which is slidably set in the inner cavity of the moving slot (112) of the placement platform (11), and pushes the moving block (3) to slide down along the moving slot (112); the first swing arm (31) and the second swing arm (311) at the bottom of the moving block (3) move down synchronously with the moving block (3), and rotate with the assistance of the rotating rod (312), bearing (313) and torsion spring (314). The ends of the first swing arm (31) and the second swing arm (311) away from the moving block (3) are lifted up, generating an upward lifting force on the lifting plate (32), which drives the plaster line body (16) above the lifting plate (32) to move up to the appropriate position required for the film. Step 4: After the plaster line body (16) rises to the designated position, the staff controls the second flip plate (152) on both sides of the inner cavity of the rectangular slot (111) of the placement platform (11) to flip around the first rotating component (154); at the same time, the existing pushing equipment is started to push the first film body (132) and the second film body (133) that have been unwound to move in opposite directions, so that the two films are tightly attached and completely wrapped on the side wall of the plaster line body (16), thus completing the vertical film wrapping operation of the plaster line body (16). Step 5: After the film wrapping operation is completed, the output end of the hydraulic cylinder (2) is reset, which drives the L-shaped placement plate (21), C-shaped connecting plate (211), connecting plate (22), positioning plate (222) and mounting plate (23) back to their initial positions. The first flipping plate (15), moving block (3), first swing arm (31), second swing arm (311) and lifting plate (32) return to their initial state under the reset characteristics of their own structure or the action of auxiliary components. Then, the packaged gypsum line body (16) is taken out to prepare for the film wrapping of the next batch of gypsum lines.
