Abstract

The present invention discloses a film covering supply device with automatic double-roll switching, specifically including a frame, a first rotating roll device arranged on the frame and used for placing a working film roll to supply film covering, a second rotating roll device arranged on the frame and used for placing a spare film roll, and a synchronous paper connecting device arranged on the frame. After the joint of the spare film roll on the second rotating roll device is pulled to move synchronously with the film supplied by the working film roll on the first rotating roll device, they are mutually pressed and connected through the double-sided adhesive tape paper on the joint of the spare film roll. The present invention pulls the joint part of the spare film roll to move independently through the synchronous paper connecting device, and moves synchronously with the film for film covering released from the working film roll. When the joint of the spare film roll and the film of the working film roll are mutually attached and connected through the double-sided adhesive tape paper, the connection between the two is a surface contact, which improves the stability after connection at the joint, and avoids the problem that the quality of gypsum board production is affected due to the disconnection between the joint and the film.

Description

Technical Field

[0001] The present invention relates to the technical field of gypsum board film covering, and particularly relates to a film covering supply device with double-roll automatic switching. Background Art

[0002] Gypsum board is a material widely used in the field of building construction, and has excellent properties such as sound insulation, heat insulation and fire prevention. During the production process, it needs to go through multiple processes, and film covering is one of them. Generally, a paper splicing machine connects the front and rear two film rolls to ensure the continuous progress of the film covering process on the production line. The synchronous paper splicing machine is one type of paper splicing machine.

[0003] During the process of covering the gypsum board with a synchronous paper splicing machine, since the length of the film on the film roll is limited, when the film on the front film roll is about to run out, the paper splicing machine connects the joint part on the spare film roll with the film released from the working film roll into one body, and cuts off the connection between the film and the working film roll. At this time, the connection between the two film rolls is completed, so that the production line can continue to operate.

[0004] However, during the paper splicing process of the synchronous paper splicing machine, the spare film roll and the working film roll need to rotate synchronously and approach each other, so that the double-sided adhesive paper on the joint of the spare film roll contacts the film of the working film roll and is connected together. The contact mode between the spare film roll and the working film roll is line contact, and the contact time is very short, which affects the connection stability between the joint of the spare film roll and the film of the working film roll, and leads to the influence on the production quality of the gypsum board. Summary of the Invention

[0005] The purpose of the present invention is to provide a film covering supply device with double-roll automatic switching, which solves the problem that the contact mode between the film of the spare film roll and the working film roll during the paper splicing of the existing gypsum board by the synchronous paper splicing machine is line contact and the contact time is short, which affects the connection stability and causes the influence on the production quality of the gypsum board.

DETAILED DESCRIPTION

[0032] 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.

[0033] like Figures 1 to 3 As shown, the present invention provides a double-roll automatic switching film supply device, which specifically includes:

[0034] Rack 1.

[0035] The first rotating roller device 2 is arranged on the frame 1 and is used for placing the working film roll for supplying the laminating film.

[0036] The second rotating roller device 3 is arranged on the frame 1 and is used for placing the spare film roll.

[0037] The synchronous paper splicing device 4 is arranged on the frame 1, and presses the film supplied by the working film roll on the first rotating roller device 2 after the joint of the spare film roll on the second rotating roller device 3 moves synchronously with each other, and is connected by the double-sided tape on the joint of the spare film roll.

[0038] When the present invention is in use, the first rotating roller device 2 is used to install the working film roll and release the film by rotation to supply the gypsum board for the laminating process.

[0039] The second rotating roller device 3 is used to place the spare film roll, and when the working film roll is almost used up, the joint part on the spare film roll is connected with the film on the working film roll through the synchronous paper splicing device, so that the coating process of the gypsum board can continue, and it has a rotating function.

[0040] When the synchronous paper splicing device 4 is in use, the joint on the standby film roll is pulled separately and moved synchronously with the film of the working film roll. When the joint part of the standby film roll contacts the film on the working film roll, they are pressed together, so that the joint of the standby film roll and the film of the working film roll are connected by the double-sided tape on the joint, and the working film roll and the film are cut apart by the cutting part on the existing equipment, so that the standby film roll is transformed into the working film roll to supply film for the laminating process.

[0041] Since the joint of the spare film roll is pulled separately and moves synchronously with the membrane of the working film roll, there is surface contact between the joint of the spare film roll and the membrane of the working film roll, which increases the contact area during connection, thereby improving the stability after connection and avoiding the production quality of the gypsum board being affected due to the joint of the spare film roll being disconnected after being connected with the membrane of the working film roll.

[0042] Secondly, the joint of the spare membrane roll moves and connects synchronously with the membrane of the working membrane roll, which prolongs the contact time when the two are connected and further improves the stability after connection.

[0043] The joint of the standby membrane roll and the membrane of the working membrane roll move synchronously to avoid relative movement between the two to cause friction and damage.

[0044] In this embodiment, the first rotating roller device 2 and the second rotating roller device 3 are both roller bodies that can rotate automatically.

[0045] The synchronous paper splicing device 4 comprises a synchronous traction structure 401 and a synchronous receiving structure 402 which are arranged on the frame 1 , and a joint fixing structure 403 is arranged on the synchronous traction structure 401 .

[0046] Among them, the joint fixing structure 403 fixes the joint of the spare film roll by adsorption, and pulls the joint of the spare film roll and the film released by the working film roll to move synchronously and gradually approach each other through the synchronous traction structure 401, and the synchronous supporting structure 402 is used to provide a bearing plane that moves synchronously with the working film roll to carry the film released by the working film roll when the joint of the spare film roll is connected with the film released by the working film roll.

[0047] When the synchronous paper splicing device 4 is in use, the joint of the spare film roll is fixed to the synchronous traction structure 401 through the joint fixing structure 403, and the joint of the spare film roll is pulled by the synchronous traction structure 401 to move synchronously and parallel to the film of the working film roll. At the same time, the synchronous receiving structure 402 carries the film of the working film roll and moves synchronously when the synchronous traction structure 401 pulls the joint of the spare film roll into contact with the film of the working film roll.

[0048] This ensures that the joint of the spare film roll has a supporting plane force when it is pressed against the film of the working film roll, which ensures that the double-sided tape on the joint is in full contact with the film of the working film roll to improve the stability of the connection, and avoids relative displacement between the joint of the spare film roll, the film of the working film roll and the synchronous supporting structure 402, which may cause damage to the membrane.

[0049] The synchronous traction structure 401 includes a telescopic device 404 arranged on the frame 1, a connecting plate 405 is arranged at the end of the telescopic device 404, a linear motion structure 406 that moves along the length direction of the connecting plate 405 is arranged on the connecting plate 405, and the joint fixing structure 403 is arranged on the linear motion structure 406, and the telescopic device 404 moves in a direction perpendicular to the bearing plane of the synchronous supporting structure 402.

[0050] When the synchronous traction structure 401 is in use, the joint on the spare film roll is fixed to the linear motion structure 406 through the joint fixing structure 403 and the film moves synchronously with the working film roll under the drive of the linear motion structure 406, so as to avoid relative displacement between the joint of the spare film roll and the film of the working film roll when they contact, causing damage to the film.

[0051] Secondly, the telescopic device 404 drives the connecting plate 405 to drive the linear motion structure 406 to move in the direction of the film close to the working film roll until the joint of the spare film roll and the film of the working film roll are attached to each other and the double-sided tape is pressed to connect the joint of the spare film roll and the film of the working film roll, thereby ensuring that the gypsum board laminating process can continue.

[0052] A roller 407 is disposed at one end of the connecting plate 405 , and the roller 407 is located in an area outside the two ends of the connecting plate 405 and is used to support the film to enter the area between the two ends of the connecting plate 405 .

[0053] The roller 407 is provided to avoid the problem of the linear motion structure 403 being scratched and damaged by the end of the connecting plate 405 when driving the joint of the spare film roll to move along the length direction of the connecting plate 405.

[0054] The position of the film on the roller 407 and the position of the film on the linear motion structure 406 are both at the same distance from the side of the connecting plate 405 facing away from the telescopic device 404 .

[0055] The portion of the membrane behind the joint of the standby membrane roll pulled by the linear pulling structure 407 is parallel to the connecting plate 405, thereby increasing the area where the joint and membrane on the standby membrane roll contact the membrane on the working membrane roll, further improving the stability of the connection.

[0056] The synchronous supporting structure 402 includes a support plate 408 arranged on the frame 1, and a unidirectional motion structure 409 is arranged on the support plate 408, which moves in a direction perpendicular to the film released by the working film roll, and a synchronous motion component 410 is arranged on the unidirectional motion structure 409, which moves along the movement direction of the film released by the working film roll, and the synchronous motion component 410 is provided with a bearing plate 411 for contacting the film.

[0057] When the synchronous receiving structure 402 is in use, the support plate 408 is used to provide a mounting position.

[0058] The synchronous motion structure 410 is used to drive the supporting plate 411 to move synchronously with the membrane of the working membrane roll, and drives the supporting plate 411 to gradually approach the membrane of the working membrane roll through the unidirectional motion structure 409, so that after the supporting plate 411 contacts the membrane of the working membrane roll, it provides support for the pressing action between the joint of the standby membrane roll and the membrane of the working membrane roll, so that the head of the standby membrane roll and the membrane of the working membrane roll are in full contact, ensuring the effectiveness and stability of the connection.

[0059] Secondly, the synchronous motion component 410 moves when the carrier plate 411 is close to the film of the working film roll and is about to contact it, so as to ensure that the carrier plate 411 has sufficient travel to provide support for the contact and pressing of the joint of the standby film roll and the film of the working film roll, thereby reducing the required movement distance.

[0060] In this embodiment, the linear motion structure 406, the unidirectional motion structure 409 and the synchronous motion component 410 are all mechanical structures that move along a linear motion, for example, they can be driven by a screw or a cylinder, etc., as long as they can move along a linear motion.

[0061] A positioning roller 412 is provided on the frame 1 , and when the supporting plate 411 contacts the positioning roller 412 , the supporting plate 411 contacts the film, and the axis of the positioning roller 412 is parallel to the film and perpendicular to the moving direction of the film.

[0062] The contact position between the carrier plate 411 and the film of the working film roll is positioned by the provided positioning roller 412 to prevent the carrier plate 411 from excessively moving and causing the film of the working film roll to be over-tensioned and damaged.

[0063] Furthermore, the positioning roller 412 rotates synchronously with the movement of the carrying plate 411 , so as to avoid the positioning roller 412 affecting the movement of the carrying plate 411 and causing interference.

[0064] Both ends of the support plate 411 are provided with arc chamfers.

[0065] This avoids the problem of damage caused by relative movement of the two ends of the supporting plate 411 due to the error in movement speed when they come into contact with the film of the working film roll.

[0066] The joint fixing structure 403 includes an intermediate plate 413 disposed on the linear motion structure 406 , and a plurality of air suction holes 414 connected to the air pump are evenly distributed on the intermediate plate 413 .

[0067] When the joint fixing device 403 is in use, the middle plate 413 provides a flat surface for the joint of the spare film roll to ensure that the joint of the spare film roll can be laid flat to fully fit with the film of the working film roll to avoid wrinkles that affect the production quality of the gypsum board.

[0068] A negative pressure suction force is generated by setting up multiple suction holes 414 to adsorb and fix the joint part of the spare film roll, so that the joint of the spare film roll can be fixed to move with the traction of the linear motion structure 406, and avoid the problem of damaging the surface of the joint of the spare film roll and occupying the space of the adhesive connection caused by downward pressure fixation.

[0069] One end of the middle plate 413 is provided with two lifting devices 415 which are raised and lowered along a direction parallel to the movement of the linear motion structure 406, wherein the end of one of the lifting devices 415 is provided with a pressing plate 416 for pressing down and fixing a part of the joint of the spare film roll, and the end of the other lifting device 415 is provided with a cutting knife 417 for cutting off the pressed and fixed joint part.

[0070] The two lifting devices 415 are sequentially arranged along a straight line perpendicular to a side of the middle plate 415 facing away from the telescopic device 404 , and the pressing plate 416 is located between the cutter 417 and the connecting plate 405 .

[0071] A small part of the end of the joint of the spare film roll is driven by the lifting device 415 to move the pressing plate 416 to be pressed between the pressing plate 416 and the end of the middle plate 413, and after the joint of the spare film roll and the film of the working film roll are connected, the lifting device 415 drives the cutter 417 to cut off the released part pressed under the pressing plate 416, so as to avoid this part of the joint from curling due to not being connected to the film of the working film roll and affecting the production quality of the gypsum board, and the stability of the joint when fixed is further improved by the pressing of the pressing plate 416.

[0072] In this embodiment, the telescopic device 404 and the lifting device 415 are both existing mechanical devices, such as electric push rods or hydraulic push rods, which are mechanical structures that can adjust their own lengths.

The protection scope of the present application is defined by the claims.
