Description

Technical Field

[0001] This application relates to the field of gypsum board production technology, specifically to a gypsum board edge banding and cutting device. Background Technology

[0002] Gypsum board is a material made primarily from building gypsum. It is a lightweight, high-strength, thin, and easy-to-process building material with good sound insulation, heat insulation, and fire resistance properties, making it one of the new lightweight building materials currently under development. Gypsum board is widely used in various buildings such as residences, office buildings, shops, hotels, and industrial plants for interior partitions, wall cladding, ceilings, sound-absorbing panels, floor baseboards, and various decorative panels. However, it is not suitable for installation in bathrooms or kitchens.

[0003] During the production of gypsum board, the gypsum at both ends is exposed, making it prone to granulation shedding during transportation and affecting the appearance of the gypsum board. Therefore, it is necessary to seal the ends of the gypsum board, i.e., edge sealing. Edge sealing involves sealing the exposed gypsum at the ends of the gypsum board with edge sealing tape. Edge sealing is a continuous process, and after the edge sealing is completed, the edge sealing tape between the two sets of boards needs to be cut.

[0004] In the past, edge banding tape was cut by piercing it with a toothed blade, resulting in uneven cross-sections that seriously affected the appearance quality of the gypsum board. Summary of the Invention

[0053] See attached document Figures 1 to 2 As shown in the figure, this application provides a gypsum board edge banding cutting device, including a conveying roller 1, a lifting partition mechanism 2, and a cutting mechanism 3. The conveying roller 1 is used to convey gypsum board. The lifting partition mechanism 2 is disposed at the bottom of the conveying roller 1. When the lifting partition mechanism 2 is in the highest position, it blocks the gypsum board between adjacent gypsum boards. When the lifting partition mechanism 2 is in the lowest position, it releases the gypsum board. The cutting mechanism 3 is disposed at the top of the conveying roller 1 and is used to cut the edge banding strip between adjacent gypsum boards.

[0054] Because the traditional method of cutting gypsum board edge banding involves using a toothed blade to sever the banding, the resulting cross-section is uneven, which seriously affects the appearance quality of the gypsum board.

[0055] In this embodiment, by setting up a lifting partition mechanism 2, the partition mechanism can be raised to block the edge banding strip between two adjacent gypsum boards, thus isolating the edge banding strip between the two adjacent gypsum boards. This allows the high-speed rotating cutting mechanism 3 to accurately cut the edge banding strip to ensure a neat cut surface and improve the aesthetics of the gypsum board edge banding after cutting.

[0056] As described above, the traditional conveyor roller 1 structure includes a roller frame, several roller bodies mounted on the roller frame, a transmission mechanism that drives all roller bodies to rotate synchronously, and a conveyor motor. One end of the conveyor roller 1 is the feed inlet, and the other end is the discharge outlet. The cutting mechanism 3 and the lifting partition mechanism 2 are located between the feed inlet and the discharge outlet.

[0057] To achieve the lifting movement of the lifting partition mechanism 2, in a preferred embodiment, such as... Figures 4 to 8 As shown, the lifting partition mechanism 2 includes an I-beam, an incomplete gear 202, a first motor 203, a spring pin, and a reset mechanism. The I-beam includes a longitudinal beam 207, a first crossbeam 205, and a second crossbeam 206. The first and second crossbeams 205 and 206 are integrally formed at both ends of the longitudinal beam 207. The first crossbeam 205 is located near the feed inlet of the conveyor roller 1, while the second crossbeam 206 is located near the discharge outlet of the conveyor roller 1. A baffle 217 is vertically installed on both the first and second crossbeams 205 and 206. The baffle 217 is located in the gap between adjacent rollers and can protrude from the upper surface of the conveyor roller 1 during the mechanism's upward movement. A downward-pointing rack 201 is vertically installed in the middle of the longitudinal beam 207.

[0058] Continue as Figures 4 to 8 As shown, the incomplete gear 202 is disposed on one side of the rack 201 and can intermittently mesh with the rack 201 during rotation. A lever 204 is welded to the gear disk surface of the incomplete gear 202. The lever 204 rotates with the incomplete gear 202. A pin hole 208 is provided on the side of the rack 201 away from the incomplete gear 202. The pin hole 208 is close to the top of the rack 201. At the same time, the output end of the first motor 203 is connected to the incomplete gear 202, so that the incomplete gear 202 is driven to rotate by the first motor 203.

[0059] Meanwhile, the spring pin is located on the side of the rack 201 away from the incomplete gear 202. When the lifting partition is not in the lowest position, the spring pin is separated from the pin hole 208. In this state, the spring pin is in a compressed state and abuts against the back of the rack 201. When the lifting partition mechanism 2 is in the lowest position, the spring pin pops out and gets into the pin hole 208. At the same time, the spring pin is provided with a push rod 212 extending towards the side of the incomplete gear 202. During the rotation of the incomplete gear 202, when the push rod 212 contacts the lever 204, the lever 204 can push the push rod 212 away from the side of the incomplete gear 202.

[0060] In addition, a reset mechanism is provided at the bottom of the rack 201. The reset mechanism is used to reset the lifting partition at the lowest position to the state of protruding from the top surface of the conveyor roller 1.

[0061] As can be seen from the above, in this embodiment, such as Figure 9 and Figure 10As shown, in the initial state, the lifting partition mechanism 2 is in its highest state. When the first gypsum board 6 is about to reach the first crossbeam 205, the first motor 203 drives the incomplete gear 202 to rotate at a low speed. At this time, the incomplete gear 202 meshes with the rack 201, thereby driving the rack 201 to move downwards, driving the I-beam downwards, so that the baffle 217 is hidden at the bottom of the conveyor roller 1. In this process, two states are experienced. The first state is when the baffle 217 just descends to be flush with the conveyor roller 1, at which time the gypsum board 6 can pass smoothly. The second state is when the incomplete gear 202 and the rack 201 finish meshing, and the I-beam is in its lowest state. At this time, the spring pin springs into the pin hole 208, locking the rack 201 to prevent it from resetting under the action of the reset mechanism. As the incomplete gear 202 continues to rotate until the lever 204 contacts the push rod 212, During the period from when the baffle 217 just descends to be flush with the conveying roller 1 until the contact between the push block 204 and the push rod 212 ends, the gypsum board 6 continues to be conveyed. During this period, the first gypsum board 6 just moves to the second crossbeam 206, and the second gypsum board 6 just moves to the first crossbeam 205. When the gypsum board 6 is in place, the contact between the push block 204 and the push rod 212 ends. During the contact between the push block 204 and the push rod 212, the push block 204 applies a pushing force to the push rod 212 away from the incomplete gear 202, thereby pushing the spring pin backward out of the pin hole 208. Under the action of the reset mechanism, the rack 201 quickly resets upward to the initial state. At this time, the baffle 217 on the first crossbeam 205 blocks the two adjacent gypsum boards 6, and the baffle 217 on the second crossbeam 206 blocks the front of the first gypsum board 6. After the contact between the push block 204 and the push rod 212 ends, the incomplete gear 202 remains disengaged from the rack 201. During this process, the conveying roller 1 needs to be stopped. During the time between the contact between the push block 204 and the push rod 212 and the re-engagement of the incomplete gear 202 and the rack 201, the rack 201 is in its highest position and does not move. During this time, the cutting mechanism 3 completes the cutting action. After the cutting is completed, the rack 201 and the gear re-engage, and the rack 201 moves downward to release the cut board. At this time, the second gypsum board 6 and the third gypsum board 6 repeat the cutting process of the first gypsum board 6 and the second gypsum board 6.

[0062] Of course, in the above embodiment, a support plate 213 is provided between the legs of the roller frame, and the lifting partition mechanism 2 is fixed on the support plate 213.

[0063] In order to accurately detect the position of the plasterboard and thus control the start and stop status of the first motor 203, the second motor 304, the telescopic cylinder 307, and the conveying roller 1 in a timely manner, in a preferred embodiment, such as Figures 1 to 2As shown, a first photoelectric sensor 4 and a second photoelectric sensor 5 are provided on the conveyor roller 1. The first photoelectric sensor is closer to the feed inlet of the conveyor roller 1 than the first crossbeam 205, and the second photoelectric sensor 5 is directly opposite the second crossbeam 206.

[0064] In the above embodiment, when the first photoelectric sensor 4 detects the gypsum board, the first motor 203 is activated; when the second photoelectric sensor 5 detects the gypsum board, the conveying roller 1 stops, and the telescopic cylinder 307 operates and the second motor 304 is activated.

[0065] As is known, a photoelectric sensor includes a light-emitting part and a light-receiving part. The light-emitting part emits visible light (such as red or green) or infrared light, and the light-receiving part receives the light source and converts it into an electrical signal. The light-emitting part continuously emits a light beam. When an object blocks or reflects the light, the light intensity detected by the light-receiving part changes, triggering the output of an electrical signal. Therefore, the light-receiving and light-emitting parts are located on both sides of the roller frame.

[0066] In a preferred embodiment, such as Figures 7 to 8 As shown, the spring pin includes a pin seat 209, a first spring 210, and a pin head 211. The pin seat 209 is fixed on the support plate 213. The pin seat 209 has a countersunk hole on the side facing the rack 201. The first spring 210 is fixedly disposed in the countersunk hole. The pin head 211 is fixedly connected to the first spring 210. When the first spring 210 is in a compressed state, it pushes the pin head 211 to abut against the rack 201. The push rod 212 is integrally formed on the outer wall surface of the pin head 211.

[0067] As can be imagined, in the above embodiment, when the rack 201 engages with the incomplete gear 202 and moves downward to the lowest position, the pin 211 is springed into the pin hole 208 by the first spring 210, locking the rack 201 from resetting. As the incomplete gear 202 rotates, the lever 204 contacts the push rod 212 and applies a pushing force away from the side of the incomplete gear 202 to the push rod 212. Since the push rod 212 is fixed to the pin 211, the pin 211 is pushed out of the pin hole 208 by the backward pushing force. The rack 201 resets because it is not engaged with the incomplete gear 202.

[0068] In a preferred embodiment, such as Figures 7 to 8 As shown, the reset mechanism includes a rack guide rail 214 fixedly mounted on the bottom surface of the support plate 213. The support plate 213 has a through hole from top to bottom for the rack 201 to pass through. The rack 201 is slidably mounted in the rack guide rail 214. The rack guide rail 214 guides the movement of the rack 201 to ensure the linearity of the rack 201's movement. A second spring 215 is provided at the bottom of the rack guide rail 214. A guide rod 216 is provided at the center of the shaft of the second spring 215. The guide rod 216 is fixed to the inner bottom surface of the rack guide rail 214. The rack 201 has a guide hole from bottom to top for the guide rod 216 to be inserted.

[0069] From the above embodiments, it is easy to see that when the rack 201 moves downward, it will compress the second spring 215. When the spring pin exits the pin hole 208, the rack 201 will quickly pop out under the action of the second spring 215, thereby blocking the baffle 217 between the plasterboards.

[0070] In a preferred embodiment, such as Figure 3 As shown, the cutting device includes a cutting blade 301, a driven sprocket 302, a driving sprocket 303, a second motor 304, and a telescopic cylinder 307. The cutting blade 301 and the driven sprocket 302 are coaxially arranged. The driving sprocket 303 is connected to the driven sprocket 302 via a synchronous chain. The output end of the second motor 304 is connected to the driving sprocket 303. Simultaneously, a cutting device is provided on each side of the roller frame. An L-shaped fixing plate is welded to the roller frame, extending inwards. A lifting guide rail 306 is vertically fixed on the fixing plate. A mounting plate 305 is slidably installed inside the lifting guide rail 306. The telescopic cylinder 307 is fixedly installed at the top of the lifting guide rail 306, and its output end is fixedly connected to the mounting plate 305. The second motor 304 and the shaft connecting the driven sprocket 302 and the cutting blade 301 are both mounted on the mounting plate 305.

[0071] From the above embodiments, it is easy to imagine that the telescopic cylinder 307 can drive the entire cutting device to move up and down, thereby completing the cutting of the edge banding.

[0072] In a preferred embodiment, such as Figures 1 to 3 As shown, the cutting device is located on the first crossbeam 205, and two baffles 217 are provided at each end of the first crossbeam 205. The cutting device cuts the edge banding strip between the baffles 217, while a baffle 217 is provided at each end of the second crossbeam 206.

[0073] It is conceivable that two baffles 217 are set between two adjacent plasterboards, and the cutting device is located between the baffles 217, so that the two plasterboards in front and behind are separated by the two baffles 217, that is, the separating sealing strip, so that the high-speed rotating cutting blade 301 can cut out a flat surface.

[0074] In summary, the working process of the gypsum board edge banding and cutting device provided in this application embodiment is as follows:

[0075] The sealed gypsum board is transferred to the conveyor roller 1. The gypsum board is conveyed along the conveyor roller 1. When the first photoelectric sensor detects the gypsum board, the first motor 203 starts and drives the incomplete gear 202 to rotate. The incomplete gear 202 then meshes with the rack 201. The rack 201 drives the I-beam to move downward, thus allowing the gypsum board to be conveyed forward. When the incomplete gear 202 and the rack 201 finish meshing, the rack 201 moves to the lowest position. At this time, the pin head 211 is pushed into the pin hole 208 by the first spring 210, locking the rack 201 to prevent it from rising and resetting. As the incomplete gear 202 continues to rotate, it no longer meshes with the rack, so the rack 201 will not move. During this stage, the inner baffle 217 will not obstruct the movement of the plasterboard. Until the incomplete gear 202 rotates to the point where the lever 204 contacts the push rod 212, as the incomplete gear 202 continues to rotate, the lever 204 will apply a pushing force to the push rod 212 away from the incomplete gear 202, so that the pin head 211 is pushed out of the pin hole 208. The rack 201 will quickly spring up under the action of the second spring 215, forming a block on the plasterboard. At this time, the baffle 217 on the first crossbeam 205 is located between adjacent plasterboards, while the plasterboard on the second crossbeam 206... The plasterboard is blocked in front of the previous plasterboard. At the same time, the second photoelectric sensor 5 detects the plasterboard and shuts off the conveyor roller 1. Simultaneously, the telescopic cylinder 307 starts to extend downward. Since the incomplete gear 202 has not yet engaged with the rack 201, the incomplete gear 202 continues to rotate. The baffle 217 will remain blocking the plasterboard. During this time period, as the telescopic cylinder 307 extends, the second motor 304 drives the drive sprocket 303 to drive the driven sprocket 302, thereby causing the cutting blade 301 to rotate at high speed and cut the edge banding. Then the telescopic cylinder 307 shortens and resets, and the incomplete gear 202 re-engages with the rack 201. At this time, the conveyor roller 1 restarts, and the plasterboard is conveyed to enter the next round of cutting.

[0076] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
