Description

Technical Field

[0001] This invention relates to the field of gypsum board manufacturing technology, and more specifically to an automatic replaceable edge banding supply device. Background Technology

[0002] Gypsum board is a material made primarily from building gypsum. It is a lightweight, high-strength, thin, easy-to-process building material with good sound insulation, heat insulation, and fire resistance properties. It is one of the new lightweight building materials that is currently being developed. During the production process of gypsum board, edge sealing is required, and the edge sealing tape needs to be replaced in the three-control edge sealing process in the gypsum board factory production workshop.

[0003] Traditionally, operators manually change the gypsum board rolls, but this often happens because operators forget to change to the next roll due to negligence. This affects the gypsum board edge banding work, making it impossible to continue the edge banding process. These unsealed boards become waste, causing unnecessary production waste.

[0004] Existing technologies have also addressed this issue through various technical solutions, such as installing alarm devices to provide early warnings about the condition of the edge banding tape. These warning signals replace manual observation, thus resolving the problem of operators forgetting to replace the tape. However, this solution has drawbacks; operators still need to shut down the edge banding machine, replace the tape, and then restart it, resulting in low replacement efficiency.

[0005] Regardless of whether it is a traditional or existing technical solution, without shutting down the machinery, the solution cannot ensure timely reconnection of the edge banding tape during the edge banding work of gypsum board, and does not effectively solve the problem of replacing the edge banding tape.

[0006] Therefore, existing technologies still cannot fundamentally solve the problem of automatically splicing and replacing edge banding. Summary of the Invention

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] like Figure 1 The present invention provides an automatic replaceable edge banding tape supply device, including a conveying platform 1, a tape changing mechanism 2, a monitoring structure 3, a cutting and bonding mechanism 4, and a microcomputer 5; wherein, the tape changing mechanism 2 is disposed on the conveying platform 1, and the tape changing mechanism 2 includes a drive tape changing component 21 and a tape feeding component 22. The drive tape changing component 21 is disposed on one side of the edge banding tape on the surface of the conveying platform 1, and the tape feeding component 22 is disposed on one side of the drive tape changing component 21. The tape feeding component 22 includes a guide roller 221 and at least two sets of paper roll holders 222. The guide roller 221 is disposed on one side of the conveying platform 1, and the paper roll holders 222 are disposed at the center of the conveying platform 1 where the edge banding tape is installed. The drive tape changing component 21 includes a tape changing drive wheel 211, and the tape changing drive wheel 211 has two sides... Each is equipped with a belt-changing driven wheel 212. The belt-changing driving wheel 211 and the belt-changing driven wheel 212 are located on both sides of the sealing belt. The belt-changing driving wheel 211 is driven to rotate clockwise. The belt-changing driving wheel 211 and the belt-changing driven wheel 212 on one side transmit the sealing belt, and at the same time, the sealing belt transmitted by the belt-changing driven wheel 212 and the belt-changing driving wheel 211 on the other side is withdrawn. The belt-changing driving wheel 211 is then driven to rotate counterclockwise, and the sealing belt transmission direction is reversed. The monitoring structure 3 is located on one side of the sealing belt. The monitoring structure 3 has a photoelectric switch 31. The photoelectric switch 31 sets the sealing belt as a reference object and sets the radius of the sealing belt as the sensing distance. The photoelectric switch 31 monitors the use of the sealing belt and releases a signal when the photoelectric switch 31 loses the reference object.

[0053] In addition, the cutting and bonding mechanism 4 is fixedly installed on one side of the conveying platform 1. The cutting and bonding mechanism 4 has a cutting component 41 and an automatic bonding component 42. The automatic bonding component 42 is installed on one side of the guide roller 221, and the cutting component 41 is installed on one side of the automatic bonding component 42. The automatic bonding component 42 has a bonding block 421. The bonding block 421 has an arc-shaped structure. The bonding block 421 is mated and pressed with the guide roller 221. The edge sealing tape is pressed and bonded to the guide roller 221 through the bonding block 421. The cutting component 41 and the automatic bonding component 42 are connected to a drive component 43. The conveying platform 1 completes the edge sealing tape splicing work by driving the drive component 43. The microcomputer 5 is installed on the conveying platform 1. The microcomputer 5 is electrically connected to the power supply of the drive component 43 and the signal transmission source of the photoelectric switch 31. The microcomputer 5 receives the signal released by the photoelectric switch 31 and drives the drive component 43 to perform the edge sealing tape replacement splicing work.

[0054] In the above implementation scheme, a microcomputer 5 is provided. This device uses the microcomputer 5 to receive the signal released by the photoelectric switch 21 when the edge banding tape is used up, which can avoid the situation where the edge banding tape is used up but is forgotten to be replaced due to human negligence. In addition, the tape changing mechanism 2 controls the entry of different edge banding tapes and the exit of the excess part of the previous edge banding tape according to the rotation direction of the tape changing drive wheel 211. It is suitable for the replacement and transmission of different edge banding tapes, ensuring the timely replacement of edge banding tapes.

[0055] This invention enables the replacement and transmission of the sealing tape via a tape-changing drive wheel 211 and a tape-changing driven wheel 212. Both the tape-changing drive wheel 211 and the tape-changing driven wheel 212 are connected by a rotating rod 213. The tape-changing drive wheel 211 and the tape-changing driven wheel 212 are mounted on the surface of the conveying platform 1 via the rotating rod 213 and remain rotatable. One end of the rotating rod 213 is provided with a threaded interface 214. The conveying platform 1 has multiple fixing holes 215. The tape-changing driven wheel 212 is threadedly connected to the fixing holes 215 on the conveying platform 1 through the threaded interface 214 of the connected rotating rod 213. The rotating rod 213 connected to the tape-changing drive wheel 211 is connected through the conveying platform 1.

[0056] In actual operation, the belt changing drive wheel 211 is driven to rotate clockwise or counterclockwise, and the belt changing driven wheels 212 on both sides always keep the same direction of rotation. The belt changing drive wheel 211 and the belt changing driven wheels 212 on both sides form an input space and an output space respectively because they rotate in opposite directions. The direction of rotation of the belt changing drive wheel 211 is adjusted according to the need to change the edge sealing belt.

[0057] The present invention replaces the sealing tape by driving the tape changing assembly 21. The driving part of the tape changing assembly 21 adopts the following preferred embodiment: the tape changing assembly 21 includes a driving platform 216 disposed on the side of the conveying platform 1 and a stepper motor 217 disposed in the driving platform 216; the wall of the driving platform 216 is fixed to the side of the conveying platform 1 by bolts, the tape changing drive wheel 211 is connected to the output end of the stepper motor 217, and the stepper motor 217 is electrically connected to the microcomputer 5.

[0058] During the operation of the above embodiment, by setting the direction of the stepper motor 217 to drive the belt changing drive wheel 212, the microcomputer 5 receives the signal released from the photoelectric switch 21 and controls the stepper motor 217 to change the direction of exiting the previous section of the remaining edge banding tape and continuing the subsequent edge banding tape.

[0059] In the above implementation scheme, the connection structure between the belt-changing drive wheel 211 and the stepper motor 217 is easy to replace because the direction of rotation is frequently changed. The rotating rod 213 connected to the belt-changing drive wheel 211 is connected to a steering clamp 218, and the threaded interface 214 is threadedly connected to the steering clamp 218. The rotating rod 213 connected to the belt-changing drive wheel 211 is connected to a rotating drum 219, and the steering clamp 218 is disposed inside the rotating drum 219. The output end of the stepper motor 217 is coaxially connected to a threaded rod 2110, and the threaded rod 2110 is threadedly connected to the rotating drum 219. The rotating drum 219 and the threaded rod 2110 rotate coaxially. The steering clamp 218 is provided with a gear structure, and a rack is provided inside the rotating drum 219. The steering clamp 218 and the rotating drum 219 mesh and rotate coaxially.

[0060] In the above embodiment, the steering clip 218 connected to the drive pulley 211 meshes with the rotating drum 219 connected to the stepper motor 217. As the usage time increases, the gear structure and rack responsible for meshing will wear out and will not mesh tightly. The replacement of the worn parts can be completed by removing the rotating rod 213 connected to the drive pulley 211, replacing the steering clip 218 on the rotating rod 213, taking out the stepper motor 217 from the drive table 216, rotating and removing the rotating drum 219 on the threaded rod 2110 to replace the new parts, and then reinstalling the parts in the original way.

[0061] The preferred embodiment of the tape feeding assembly 22 of the present invention is as follows: all paper roll holders 222 are arranged in a straight line on the conveying platform 1, and all photoelectric switches 31 are arranged on the same side of the paper roll holders 222; the tape feeding assembly 22 includes guide wheels 223 and guide plates 224, the guide plates 224 are arranged in the middle of adjacent sealing tapes during transportation, and the guide wheels 223 are arranged on both sides of the sealing tapes during transportation.

[0062] In the above embodiment, the tape feeding assembly 22 separates different edge banding tapes through the guide plate 224, ensuring that the edge banding tapes do not affect each other during their input and return, thus ensuring an orderly conveying process of the edge banding tapes. The guide wheel 223 is set to contact the edge banding tape, and guides the edge banding tape to be transported along the planned designated path through friction.

[0063] This invention uses a cutting assembly 41 to continuously cut the edge banding tape. The cutting assembly 41 includes a first cutter 411, which consists of a first cylinder 413 mounted on a conveying platform 1, a first cutter seat 414 connected to one end of the first cylinder 413, a short-shaft cutter rod 415 connected to the first cutter seat 414, and a first cutter head 417 connected to one end of the short-shaft cutter rod 415. The first cutter seat 414 of the first cutter 411 is fixed to the output end of the first cylinder 413, and the first cutter seat 414 of the first cutter 411 is fixedly connected to the short-shaft cutter rod 415. The first cutter head 417 is mounted on the bayonet of the short-shaft cutter rod 415.

[0064] In the above embodiment, the first cylinder 413 pushes the first cutting head 417 to continuously cut the edge banding through the short shaft cutting rod 415. As the first cylinder 413 pushes, the first cutting head 417 moves along the cutting path, and the edge banding is pre-set in the moving path to complete the cutting of the previous excess edge banding.

[0065] In the above embodiments, as more paper roll holders 222 are added to the conveying platform, the sealing tape on the transport path increases. To address this, the present invention provides a preferred solution: the cutting assembly 41 includes a second cutter 412. The second cutter 412 consists of a second cylinder 417 mounted on the conveying platform 1, a second cutter seat 418 connected to one end of the second cylinder 417, a long shaft cutter rod 419 connected to the second cutter seat 418, and a second cutter head 4110 connected to one end of the long shaft cutter rod 419. The second cutter seat 418 of the second cutter 412 is fixed to the output end of the second cylinder 417, and the second cutter seat 418 of the second cutter 412 is fixedly connected to the long shaft cutter rod 419. The second cutter head 4110 is mounted on the bayonet of the long shaft cutter rod 419.

[0066] In the above embodiment, the first cutter 411 and the second cutter 412 are symmetrically arranged on the conveying platform 1, and the cylinders of the first cutter 411 and the second cutter 412 are both connected to the drive assembly 43; the first cylinder 413 pushes the first cutter seat 414 to make a cutting motion along the first cutter head 417, and the second cylinder 417 pushes the second cutter seat 418 to make a cutting motion along the second cutter head 4110. The first cutter 411 and the second cutter 412 make cutting motions in opposite directions to complete the cutting of the edge banding tape.

[0067] The present invention arranges the first cutter 411 and the second cutter 412 in opposite directions, so that the opposing sections of the first cutter head 417 and the second cutter head 4110 form a cutting section, so that all the edge banding tape passing through the cutting section can be cut by the first cutter 411 and the second cutter 412.

[0068] The present invention uses an automatic adhesive assembly 42 to perform adhesive work for changing edge sealing tape. The automatic adhesive assembly 42 has a base 422 and a third cylinder 423. The adhesive block 421 is engaged with the base 422, the base 422 is connected to the third cylinder 423, and the third cylinder 423 is connected to the drive assembly 43. The adhesive block 421 is driven by the third cylinder 423 to perform pressing and adhesive work.

[0069] In the above embodiments, the driving of the third cylinder 423 enables the adhesive block 421 to quickly separate after being pressed and adhered to the guide roller, without affecting the continuous transmission of the edge sealing tape and ensuring rapid splicing. The application of the third cylinder 423 enables the adhesive block 421 to perform better adhesion work. The drive component 43 is connected to the first cylinder 413, the second cylinder 417 and the third cylinder 423. Under the control of the microcomputer 5, the edge sealing tape is cut and adhered in sequence to ensure the continuous work of the edge sealing tape. In actual applications, the drive component 43 is commonly used as a solenoid valve.

[0070] In the actual operation of the present invention, the adhesive block 421 is a consumable item, the adhesive block 421 is provided with an adhesive layer, and the adhesive block 421 is a detachable structure; the base 422 is provided with a groove 424 closed at one end, the adhesive block 421 is provided with a slider 425, the shape and size of the groove 424 and the slider 425 correspond, and the slider 424 can slide into the groove 425.

[0071] In the above implementation scheme, after several uses, after the device completes one edge sealing tape splicing operation, the operator slides the adhesive block 421 out of the groove 424 via the slider 425, replaces the new adhesive block 421 accessory, and installs the slider 425 along the groove 424. The structure of the groove 424 and the slider 425 can be completely and tightly embedded, and one end of the groove 424 is closed, so the slider 425 will not slide out after it is slid into the groove 424.

[0072] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
