Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting devices, and in particular to a gypsum corner protector cutting and forming device. Background Technology
[0002] In the field of building decoration materials, gypsum board is widely used in interior partitions, ceilings, and other parts of various buildings due to its advantages such as light weight, fire resistance, sound insulation, and high workability. With the booming development of the construction industry, the usage of gypsum board continues to grow, and the demand for its supporting products is also increasing, with gypsum corner guards being one of them.
[0003] In practical applications, the top and bottom edges of plasterboard packed in stacks for transport are highly susceptible to damage during handling and storage. To protect these edges, corner protectors are typically installed during packing. Traditional methods of manufacturing plasterboard corner protectors have several drawbacks. Early methods involved cutting plasterboard into strips and then manually slicing one side open with a utility knife, leaving the other side intact for folding into corner protectors. This manual method is not only inefficient and reliant on manpower, but also makes it difficult to guarantee cutting precision, resulting in significant variations in the specifications of the produced corner protectors. Furthermore, the right-angle notches formed at the folding point can easily tear the packaging film during subsequent use, reducing the product's protective performance and potentially causing accidental injury to handlers.
[0004] From a production efficiency perspective, manual cutting severely restricts capacity expansion. In large-scale construction projects, the demand for gypsum corner guards is enormous, and manual operation cannot meet the required delivery speed, impacting the overall construction progress. Furthermore, rising labor costs and this inefficient production method keep production costs high, weakening the product's market competitiveness. Regarding product quality, manual cutting is affected by the operator's skill level and effort, making it difficult to standardize the cutting depth and angle. This results in inconsistent dimensional accuracy and bending performance in the produced corner guards, affecting the overall product quality and aesthetics, and reducing customer satisfaction.

[0026] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] This utility model proposes a gypsum corner protector cutting and forming device, which includes a transmission module 1 and a cutting module 2. The transmission module 1 includes a guide roller 11, a conveyor belt 12 and a base support 13. The cutting module 2 includes a shell 21, a bearing device, a guiding device, a cutting device and a dust removal device.
[0028] The transmission module 1 is responsible for transporting the gypsum board to be processed to the cutting module 2. The guide roller 11 is installed above the roller at the end of the conveyor belt 12 away from the cutting module 2. The guide roller 11 and the conveyor belt 12 are combined to transport the gypsum board in a specified shape, ensuring the smooth operation of the subsequent cutting module 2 and reducing the difficulty of manual work. The conveyor belt 12 is installed on the base bracket 13. The base bracket 13 is responsible for keeping the top plane of the conveyor belt 12 and the bottom of the feed port of the cutting module 2 horizontal, ensuring that the gypsum board enters the feed port smoothly.
[0029] In the cutting module 2, the guiding device includes a first pressure roller 231, a second pressure roller 232, a third pressure roller 233, a fourth pressure roller 234, and two guide rods 235; the carrying device includes six carrying plates 22, which correspond to the six sets of pulleys of the conveyor belt 12, and each carrying plate 22 has pre-set holes at both ends; the cutting device includes a first cutting array 241 and a second cutting array 242; the outer shell 21 is responsible for carrying the other devices in the cutting module 2, and is provided with a discharge port and a feed port for the entry of gypsum board to be processed and the output of gypsum corner protectors.
[0030] The first pressure roller 231 and two guide rods 235 are installed at the feed inlet of the housing 21. The guide rods 235 are installed close to the housing 21 on the outer side below the first pressure roller 231, extending from the inside of the housing 21 through the feed inlet to the upper sides of both sides of the conveyor belt 12. The part of the guide rods 235 extending out of the housing 21 is arc-shaped. Except for the extended part of the guide rods 235 and the first pressure roller 231, the other parts of the cutting module 2 are installed inside the housing 21. The feed inlet is located at the connection between the transmission module 1 and the cutting module 2. The guide rods 235 are responsible for fine-tuning the gypsum board to be processed to ensure smooth entry into the feed inlet.
[0031] The second pressure roller 232, the third pressure roller 233, and the fourth pressure roller 234 are all at the same height as the first pressure roller 231. The second pressure roller 232 is located behind the first pressure roller 231, the third pressure roller 233 is located behind the second pressure roller 232, and the fourth pressure roller 234 is located behind the third pressure roller 233. The discharge port is located behind the fourth pressure roller 234. The second pressure roller 232 and the third pressure roller 233 are used to adjust the shape of the gypsum board and make the gypsum board fit tightly with the bearing device to ensure the cutting effect. The fourth pressure roller 234 is used to ensure that the processed gypsum corner guards can pass smoothly through the discharge port.
[0032] The supporting device and the cutting device are located below the second pressure roller 232. The drive shafts of the first cutting array 241 and the second cutting array 242 are both located below the supporting plate 22 and at the same height. The first cutting array 241 is located between the second pressure roller 232 and the third pressure roller 233, and the milling cutter of the first cutting array 241 is slightly higher than the supporting plate 22 and passes through the supporting plate 22. The second cutting array 242 is located between the third pressure roller 233 and the fourth pressure roller 234, and the slicing pieces of the second cutting array 242 are higher than the supporting plate 22 and located in the gaps between the supporting plates 22. The supporting device is responsible for supporting the gypsum board for processing and providing space for cutting. The milling cutter of the first cutting array 241 is slightly higher than the supporting plate 22, with a height distance slightly less than the thickness of the gypsum board, and cuts the gypsum board to form six grooves with a 90° cross-section. The slicing pieces of the second cutting array 242 are higher than the supporting plate 22, with a height distance greater than the thickness of the gypsum board, and cut the gypsum board into six uniform parts.
[0033] The dust collection hood 251 is located above the second cutting array 242; the dust collection hood 252 is located below the support device and is connected to the support device through preset holes, covering the first cutting array 241 and the second cutting array 242. The connection is made with embedded screws to ensure that there are no protrusions on the gypsum board surface supported by the support plate 22; both the dust collection hood 251 and the dust collection hood 252 are connected to external pipes to transfer and store the collected debris. By collecting the debris generated during cutting through the dust collection hood 251 and the dust collection hood 252, a clean and hygienic working environment is ensured. A clean working environment can protect the health of the staff and extend the life of the equipment.
[0034] In actual use, the worker places the plasterboard smoothly between the guide roller 11 and the conveyor belt 12. The guide roller 11 is installed above the roller at the end of the conveyor belt 12 furthest from the cutting module 2. Its surface material has a certain friction, which can effectively cooperate with the conveyor belt 12 to firmly fix the plasterboard on the conveyor belt 12. During the operation of the conveyor belt 12, the guide roller 11 not only ensures the transmission effect of the conveyor belt, allowing the plasterboard to move smoothly along the predetermined route and speed, but also restricts the movement of the plasterboard, preventing it from deviating or shaking during the conveying process.
[0035] As the conveyor belt 12 continues to operate, the gypsum board is gradually transported to the guide rod 235. The guide rod 235 extends outward from the outer casing 21 in an arc shape, curving outward from the conveyor belt 12 and installed close to the outer casing 21 below the first pressure roller 231. It extends from inside the outer casing 21 through the feed inlet to the upper sides of both sides of the conveyor belt 12. During transportation, due to factors such as mechanical vibration, the gypsum board may slightly shift. This outward-curving guide rod 235 plays a crucial role in adjusting the shape of the shifted gypsum board, ensuring that the gypsum board accurately reaches the feed inlet position.
[0036] When the gypsum board reaches the feed inlet, the first pressure roller 231 begins to function. The first pressure roller 231 is installed outside the feed inlet of the housing 21, which is located at the connection between the transmission module 1 and the cutting module 2. The first pressure roller 231 can adjust the height of the gypsum board to ensure that the gypsum board can smoothly pass through the feed inlet and enter the cutting module 2.
[0037] Upon entering the cutting module 2, the gypsum board is first supported by the support plates 22 in the supporting device. The supporting device includes six support plates 22, each corresponding to one of the six sets of pulleys on the conveyor belt 12. This design provides stable and uniform support for the gypsum board before and after cutting. During the gypsum board's forward movement, it passes through the second pressure roller 232. The second pressure roller 232 is at the same height as the first pressure roller 231 and is positioned after the first pressure roller 231. The function of the second pressure roller 232 is to further constrain the gypsum board, ensuring a tight fit between the gypsum board and the support plates 22, providing a stable processing foundation for subsequent cutting work.
[0038] Next, the first cutting array 241 begins operation. Located between the second pressure roller 232 and the third pressure roller 233, the first cutting array 241 includes a drive shaft and six milling cutters mounted on it. The milling cutters of the first cutting array 241 are slightly higher than the support plate 22, by a distance slightly less than the thickness of the gypsum board, and pass through the support plate 22. During operation, the milling cutters of the first cutting array 241 groove the center of each sixth of the longitudinally bisected gypsum board. Since only grooving is performed, and the gypsum board is not completely cut, all debris generated during grooving is located below the gypsum board, so no dust collection equipment is required above the first cutting array 241.
[0039] After being slotted by the first cutting array 241, the gypsum board continues to move forward under the drive of the conveyor belt 12, passing the third pressure roller 233. The third pressure roller 233 is also at the same height as the first pressure roller 231 and is set after the second pressure roller 232. Its function is similar to that of the second pressure roller 232, ensuring that the gypsum board is tightly attached to the support plate 22 again, preparing for the cutting work of the second cutting array 242.
[0040] Subsequently, the second cutting array 242 begins cutting the gypsum board. Located between the third and fourth pressure rollers 233 and 234, the second cutting array 242 includes a drive shaft and five cutting slices mounted on the drive shaft. The cutting slices of the second cutting array 242 are higher than the support plate 22 by a distance greater than the thickness of the gypsum board and are positioned within the gaps between the support plates 22. Under the action of the high-speed rotating cutting slices, the gypsum board is precisely cut into six longitudinally equal parts.
[0041] During the cutting of gypsum board by the second cutting array 242, a large amount of debris is generated, which splashes everywhere. To avoid the debris contaminating the working environment and to ensure the smooth progress of the cutting work, a dust collection hood 251 is installed above the second cutting array 242. The dust collection hood 251 is connected to a dust collection device through an external pipe, which can promptly absorb and collect the splashed debris.
[0042] Meanwhile, to prevent debris generated by the first cutting array 241 and the second cutting array 242 from splashing outside the equipment, a dust collection hood 252 is installed below the support device. The dust collection hood 252 is connected to the support device and covers the first cutting array 241 and the second cutting array 242, fitting tightly. External connecting pipes collect the debris, effectively preventing debris from overflowing from the dust collection hood 252.
[0043] Finally, the cut plaster corner bead is driven by the conveyor belt 12 and passes through the fourth pressure roller 234. The fourth pressure roller 234 is at the same height as the first pressure roller 231 and is set after the third pressure roller 233. It performs the final restriction and adjustment on the height of the plaster corner bead to ensure that the plaster corner bead can be smoothly sent out of the discharge port, completing the entire cutting and forming process.
[0044] The plaster corner bead cutting and forming device has significantly improved the production efficiency of plaster product processing plants. Cutting work that previously required a lot of manpower and time can now be completed quickly and accurately, and the product quality is more consistent. At the same time, the device is equipped with a complete dust removal system, which greatly improves the working environment and protects the health of the workers.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
