Description

Technical Field

[0001] The invention relates to the field of gypsum board laminating machines, and in particular to an automatic film rolling device of a gypsum board laminating machine. Background Art

[0002] The related technology of the gypsum board laminating machine involved in the subject matter disclosed in the present invention is disclosed in: a gypsum board automatic PVC film pasting device disclosed in Chinese patent publication number CN113715320A, which discloses a laminating machine that can automatically connect the film when the roll film is exhausted and the spare roll film is activated.

[0003] The film roll is installed in the safety chuck of the gypsum board laminating machine through the air expansion shaft. The air expansion shaft and the film roll together weigh about 200 to 300 kg. Since the total height of the gypsum board laminating machine is relatively high and the safety chuck is located at the highest point of the gypsum board laminating machine, when the staff replaces the film roll, they need to use a lifting mechanism to transport the air expansion shaft with the film roll to the side of the safety chuck, climb to a high place to remove the air expansion shaft and waste on the safety chuck, remove the air expansion shaft of the used film roll, and then install the new film roll and air expansion shaft on the safety chuck.

[0004] During the process of replacing the film roll, the spare film roll is rotating at high speed. After the staff has replaced the film roll, they also need to peel off the end of the film roll and pull the end of the film close to the spare film that is being transported at high speed, so that when the spare film roll is used up, the automatic film splicer can hot-press the two films together.

[0005] Therefore, during the process of replacing the roll film, workers need to work at high altitudes and be extremely close to the running machinery, which can easily cause safety accidents. Summary of the invention

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] When replacing the roll film 13 of the existing gypsum board laminating machine, the staff is required to work at high altitude, replace the unwinding roller 11 installed with the roll film 13 at the highest point of the gypsum board laminating machine, and then peel off the end of the roll film 13, and pull the end of the film 14 through the guide roller to approach the spare roll film 132 that is being transmitted at high speed. This process is relatively dangerous.

[0041] For this reason, Figure 1 As shown, an embodiment 1 of an automatic rolling device for a gypsum board laminating machine is provided to solve the above technical problems.

[0042] The main structure of Example 1 includes a traveling device 2 , a first hoist 3 , a first sling 4 , a second hoist 5 and a second sling 6 .

[0043] The traveling device 2 is used to travel on the ground or on a steel beam;

[0044] The first hoist 3 is arranged on the traveling device 2, and the first hoist 3 has an actuator that moves vertically;

[0045] The first sling 4 is connected to the actuator of the first hoist 3. The first sling 4 can grasp or release the end of the unwinding roller 11. The first sling 4 is used to drive the unwinding roller 11 to contact or disengage from the safety chuck 12 through the first hoist 3;

[0046] The second hoist 5 is arranged on the traveling device 2, and the second hoist 5 has an actuator that moves vertically;

[0047] The second sling 6 is connected to the actuator of the second hoist 5. The second sling 6 can adsorb or release the film 14. The second sling 6 is used to drive the end of the winding film 13 to approach the actuator of the automatic film splicing machine through the second hoist 5.

[0048] In this embodiment:

[0049] The unwinding roller 11 refers to an air shaft for installing the winding film 13.

[0050] The traveling device 2 adopts a rail vehicle 21. The rail vehicle 21 travels in the air through an overhead rail 22 to avoid the relatively crowded ground.

[0051] Both the first hoist 3 and the second hoist 5 adopt electric winches. The electric winches lift or lower the first sling 4 and the second sling 6 through steel cables.

[0052] There are 2 winding films 13 installed on the top of the gypsum board film laminating machine. The 2 winding films 13 are divided into a working winding film 131 and a spare winding film 132 according to the working mode.

[0053] During the working process, the end parts of the 2 winding films 13 respectively droop to the working area of the automatic film splicing machine through 2 guiding rollers. The 2 winding films 13 are parallel to each other and close to each other. When the working winding film 131 is used up, the automatic film splicing machine thermally presses and joins the end of the spare winding film 132 to the working winding film 131, and then cuts off the working winding film 131. The subsequent gypsum boards are laminated through the spare winding film 132.

[0054] The steps for replacing the winding film 13 are as follows:

[0055] S1. The safety chuck 12 releases the locking of the unwinding roller 11. The traveling device 2 drives the first hoist 3 to move so that the first sling 4 is located directly above the unwinding roller 11. The first hoist 3 lowers the first sling 4 to make it grasp the end of the unwinding roller 11, and then lifts the unwinding roller 11 to move it above the gypsum board film laminating machine.

[0056] S2, the walking device 2 drives the first hoist 3 to move, so that the first sling 4 moves to the side of the gypsum board laminating machine, and the first hoist 3 and the second hoist 5 respectively lower the first sling 4 and the second sling 6 to a height that is easy for workers to stand on the ground to operate.

[0057] S3, the staff removes the unwinding roller 11 on the first sling 4, and then mounts the unwinding roller 11 with a new roll film 13 installed on the first sling 4, then uncovers the roll film 13 and pulls out its end, and pulls the end of the roll film 13 so that it is adsorbed by the second sling 6.

[0058] S4, the first hoist 3 and the second hoist 5 respectively lift the first sling 4 and the second sling 6 to the top of the automatic laminating machine, and the walking device 2 moves the first hoist 3 and the second hoist 5 so that the first sling 4 is located directly above the safety chuck 12 to be rolled up, and the second sling 6 is located directly above the automatic film splicing machine.

[0059] S5, the first hoist 3 lowers the first sling 4 so that the end of the unwinding roller 11 is connected to the safety chuck 12, and the second hoist 5 lowers the second sling 6 so that the end of the roll film 13 is close to the execution part of the automatic film splicing machine.

[0060] S6, the first sling 4 releases the unwinding roller 11, the second sling 6 releases the roll film 13, and the first hoist 3, the second hoist 5 and the walking device 2 return to their original positions and stand by.

[0061] Further:

[0062] In the gypsum board laminating machine with a high degree of automation, such as Figures 2 - 4 As shown, when the diameter of the roll film 13 changes, the spacing between the used roll film 131 and the spare roll film 132 can be adjusted to adapt to the change, that is, the distance between the safety chuck 12 and the guide roller is adjusted.

[0063] If the safety chuck 12 is too close to the guide roller, the distance between the used roll film 131 and the spare roll film 132 is short, and the lack of a safety distance may easily cause a safety accident when replacing the roll film 13 .

[0064] If the safety chuck 12 is too far from the guide roller, after the end of the spare film roll 132 droops through the guide roller to the working area of ​​the automatic film splicer, the film 14 between the spare film roll 132 and the guide roller is likely to droop due to gravity, causing the film 14 to separate from the guide roller.

[0065] Therefore, it is necessary to adjust the distance between the safety chuck 12 and the guide roller, which requires the distance between the first hoist 3 and the second hoist 5 to be adjusted as well.

[0066] Meanwhile, since the relative positional relationship between the two winding films 13 and the guide rollers is mirror-symmetrical, the positions of the first lifting device 4 and the second lifting device 6 need to be interchangeable with each other, which also makes the positions of the first elevator 3 and the second elevator 5 need to be interchangeable with each other.

[0067] For this reason, Embodiment 2 is provided.

[0068] The first elevator 3 and / or the second elevator 5 are connected to the traveling device 2 through a sliding table 7, so that the first elevator 3 and / or the second elevator 5 can move along a horizontal direction perpendicular to the axis of the winding film 13.

[0069] In this embodiment:

[0070] The sliding table 7 adopts a ball screw sliding table or a synchronous belt sliding table. The sliding table 7 is located between the two first elevators 3. A gap 211 through which the steel cable of the second elevator 5 can pass is provided on the rail car 21. The movements of the first elevator 3 and the first lifting device 4, and the second elevator 5 and the second lifting device 6 do not interfere with each other.

[0071] Moving the position of the first elevator 3, or moving the position of the second elevator 5, or moving the positions of the first elevator 3 and the second elevator 5 simultaneously can change the distance between the first elevator 3 and the second elevator 5, and can interchange the positions of the first lifting device 4 and the second lifting device 6.

[0072] Among them, since the unwinding roller 11 and the winding film 13 are relatively heavy, the first elevator 3 should be located as close as possible to the center of gravity of the traveling device 2 to reduce the weight load exerted on the traveling device 2 by the unwinding roller 11, the winding film 13 and the first elevator 3. Therefore, it is the most ideal technical solution to only move the position of the second elevator 5.

[0073] As Figure 4 shown, only the second elevator 5 is connected to the traveling device 2 through the sliding table 7. When the first elevator 3 and the second elevator 5 exchange positions, the second elevator 5 moves between the two first elevators 3 through the sliding table 7, and the second lifting device 6 moves between the two steel cables suspending the first lifting device 4.

[0074] Furthermore:

[0075] Since the axial length of the winding film 13 is greater than the arm span of the staff, at least two staff members are required to pull the two sides of the film 14 to flatten its surface, and then attach the two sides of the film 14 to the second lifting device 6, so that the film 14 is flatly attached to the second lifting device 6.

[0076] However, in the actual production process, one worker often debugs multiple devices rather than multiple workers operating one device. Therefore, in the process of one worker attaching the film 14 to the second hanger 6, the difficulty lies in how to make the film 14 flat.

[0077] Because the roll film 13 crosses the gypsum board transmission line when loading and using, it is difficult for a worker to cross the gypsum board production line to attach the film 14 evenly to the second hanger 6. If the film 14 has problems such as wrinkles and folds, when the film 14 is hot-pressed and bonded to the roll film in use by the automatic film splicer, corresponding wrinkles will appear at the joint between the film 14 and the automatic film splicer, affecting the coating quality of the gypsum board.

[0078] In order to solve the above technical problems, Example 3 is provided.

[0079] The second lifting device 6 includes a slide rail, a slider and an adsorption assembly.

[0080] The slide rail is connected to the execution part of the second hoist 5 and crosses the gypsum board transmission line;

[0081] There are two sliders and they are slidably connected to the slide rail, and the sliding damping force between the slide rail and the slider is greater than the tension of the film 14;

[0082] The adsorption component has two and is respectively connected to the two sliders, and the adsorption component adsorbs the film 14 through negative pressure.

[0083] The staff can first move the slider to bring the two adsorption components closer to each other, then adsorb the two sides of the film 14 on the two adsorption components respectively, and then move the slider to move the two adsorption components away from each other, so that the film 14 adsorbed on the adsorption components is tensioned and kept flat.

[0084] As long as the sliding damping force between the slider and the slide rail is greater than the tension of the film 14, a worker can also attach the film 14 to the second hanger 6 and tension both sides of it.

[0085] on the other hand:

[0086] In Example 3, the walking device 2 and the second hoist 5 may cause slight shaking when moving the second sling 6. If the two sliders are close to each other, the film 14 adsorbed on the adsorption component will loosen. In order to solve this technical problem, Example 4 is provided.

[0087] The second lifting device 6 includes a slide rail, a slider, an adsorption assembly and a driver.

[0088] The slide rail is connected to the execution part of the second hoist 5 and crosses the gypsum board transmission line;

[0089] The slider has two and is slidably connected to the slide rail;

[0090] The adsorption assembly has two and is respectively connected to the two sliders. The adsorption assembly adsorbs the thin film 14 through negative pressure;

[0091] The driver has an actuator that moves along the length direction of the slide rail. The driver is connected to the slide rail and the actuator of the driver is connected to the slider. The driver is used to drive the two sliders to approach or move away from each other.

[0092] In Embodiment 4, the driver can adopt a bidirectional electric push rod or a bidirectional pneumatic cylinder. The sliders are driven by the driver to approach or move away from each other, eliminating the need for manual sliding of the sliders. At the same time, the sliding damping between the slide rail and the slider does not need to be restricted either.

[0093] On the other hand:

[0094] In Embodiment 4, the thrust of the electric push rod or the pneumatic cylinder that tensions both sides of the thin film 14 is relatively large, which can easily cause the thin film 14 to be stretched and deformed or torn. To solve this technical problem, Embodiment 5 is provided.

[0095] As Figures 7 - 10 shown.

[0096] The second lifting tool 6 includes a second cross beam 61, a first slide rail 62, a second slide rail 63, a driver 64, a slider 65, and an adsorption assembly 66.

[0097] The second cross beam 61 is connected to the actuator of the second hoist 5 and spans across the gypsum board transmission line;

[0098] The first slide rail 62 has a first end and a second end, and the first end is flexibly connected to one end of the second cross beam 61;

[0099] The second slide rail 63 has a third end and a fourth end, and the fourth end is flexibly connected to the other end of the second cross beam 61. The second end is hinged to the third end, and the hinge axis is perpendicular to the axis of the winding film 13;

[0100] The driver 64 has an actuator that moves vertically. The driver 64 is connected to the second cross beam 61, and the actuator of the driver 64 is hinged to the connection part of the second end and the third end;

[0101] The slider 65 has two and is respectively slidably connected to the first slide rail 62 and the second slide rail 63;

[0102] The adsorption assembly 66 has two and is respectively connected to the two sliders 65. The adsorption assembly 66 adsorbs the thin film 14 through negative pressure.

[0103] The driver 64 can be an electromagnetic push rod or a cylinder. The actuator of the driver 64 is hinged to the second end and the third end through a pin shaft 641. The driver 64 is used to drive the first slide rail 62 and the second slide rail 63 to change the angle around the actuator of the driver 64, so that the second spreader 6 has the following two working conditions.

[0104] As Figure 9 shown, in the first working condition, the first end is higher than the second end, and the fourth end is higher than the third end. The two sliders 65 slide along the first slide rail 62 and the second slide rail 63 respectively in the direction of approaching each other, so that the two adsorption components 66 approach each other, facilitating the staff to adsorb the two sides of the film 14 on the two adsorption components 66 respectively.

[0105] As Figure 10 shown, in the second working condition, the second end is higher than the first end, and the third end is higher than the fourth end. The two sliders 65 slide along the first slide rail 62 and the second slide rail 63 respectively in the direction of moving away from each other, so that the two adsorption components 66 move away from each other, thereby tensioning the film 14 adsorbed on the adsorption components 66.

[0106] In the above working conditions, the tension on both sides of the film 14 can be adjusted by adjusting the rotation angle of the first slide rail 62 and the second slide rail 63, that is, the tension of the film 14 can be adjusted by adjusting the stroke of the actuator of the driver 64, so that the film 14 can be fully tensioned and no irreversible deformation will occur.

[0107] Furthermore:

[0108] In Embodiment 5, the flexible connection is equivalent to the flexible connection. Similar to using a connecting piece without a fixed shape such as a chain or a rope to connect the two ends of the second cross beam 61 to the first slide rail 62 and the second slide rail 63, during the process of the traveling device 2 or the second hoist 5 moving the second spreader 6, the first slide rail 62 and the second slide rail 63 are prone to large-amplitude shaking, affecting the tension degree of the film 14. To solve this technical problem, Embodiment 6 is provided.

[0109] The two ends of the second cross beam 61 are respectively hinged with a first flap 611 and a second flap 612. The first flap 611 is hinged to the first end, and the second flap 612 is hinged to the fourth end. The hinge axes of the first flap 611 and the second flap 612 are both perpendicular to the axis of the winding film 13.

[0110] The first flap 611 and the second flap 612 can be regarded as a chain with only 1 link. By reducing the degrees of freedom of the first slide rail 62 and the second slide rail 63, the possibility of shaking of the first slide rail 62 and the second slide rail 63 during movement is reduced.

[0111] Furthermore:

[0112] Based on any one of Embodiments 3-6.

[0113] The adsorption assembly includes a vacuum cylinder 661, an air suction pipe 662, and air suction holes 663.

[0114] The vacuum cylinder 661 is fixedly connected to the slider 65, and the axis of the vacuum cylinder 661 is parallel to the axis of the winding film 13;

[0115] The air suction pipe 662 is formed at one end of the vacuum cylinder 661, and a vacuum pump sucks the air inside the vacuum cylinder 661 through the air suction pipe 662 so that a negative pressure is formed inside the vacuum cylinder 661;

[0116] The air suction holes 663 are formed on the surface of the vacuum cylinder 661, and the vacuum cylinder 661 adsorbs the film 14 through the air suction holes 663.

[0117] The vacuum pump is not shown in the figure. The staff attaches one side of the film 14 to the vacuum cylinder 661, and the vacuum cylinder 661 sucks the film 14 tightly through the air suction holes 663.

[0118] The length of the vacuum cylinder 661 should not be too long, preferably 10 cm to 20 cm, to avoid the staff sticking out wrinkles.

[0119] Furthermore:

[0120] The air suction holes 663 are formed on the bottom surface of the vacuum cylinder 661.

[0121] After the first lifting tool 4 and the second lifting tool 6 exchange positions, the staff still attaches the film 14 to the bottom surface of the vacuum cylinder 661 to avoid work mistakes caused by repeatedly modifying the attachment position.

[0122] Furthermore:

[0123] Based on any one of Embodiments 1-6.

[0124] As Figure 5 and 6 shown.

[0125] The first lifting tool 4 includes a first cross beam 41 and a hook-shaped plate 42.

[0126] The first cross beam 41 is connected to the execution part of the first hoist 3 and spans the gypsum board transmission line;

[0127] There are 2 hook-shaped plates 42, which are symmetrically arranged at both ends of the first cross beam 41. The hook-shaped plates 42 support the end of the unwinding roller 11 and allow the end of the unwinding roller 11 to radially enter and exit therein.

[0128] Specifically, an opening 421 is formed on a vertical side of the hook-shaped plate 42. The opening 421 extends to the center of the hook-shaped plate 42, and a V-shaped bottom wall 422 is formed inside the hook-shaped plate 42. The end of the unwinding roller 11 passes in and out through the opening 421, and the bottom wall 422 is used to support and position the end of the unwinding roller 11.

[0129] Furthermore:
