Description

Technical Field

[0001] This invention relates to the field of gypsum board processing technology, and more specifically to a cutting device for gypsum board lining. Background Technology

[0002] Gypsum board guards are protective materials used during the packaging of a whole stack of gypsum boards. In practical applications, gypsum board guards need to be cut according to the specifications and dimensions of the whole stack of gypsum boards, and the cut gypsum board guards need to have pre-cut slits on one side to facilitate folding along the slits when in use.

[0003] Currently, the cutting of gypsum board panels is mostly done manually: the operator manually feeds the gypsum board panel into the high-speed saw, which cuts it into a preset number of pieces. After the cutting is completed, each piece of gypsum board panel is scored by the operator. The whole process is done in steps.

[0004] In existing technologies, high-speed saws easily generate a large amount of gypsum dust during the sawing process, which pollutes the working environment. The cutting and scoring processes are carried out in separate steps, making the operation process cumbersome. Summary of the Invention

[0005] To address this, the present invention provides a cutting device for gypsum board guardrails, which solves the technical problems of existing technologies where high-speed sawing processes easily generate a large amount of gypsum dust, polluting the working environment, and the cutting and scoring processes are carried out in separate steps, resulting in a cumbersome operation process.

[0006] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution: A cutting device for gypsum board cladding, comprising: The conveyor roller conveyor has a feed roller conveyor and a discharge roller conveyor connected front and rear. The feed roller conveyor and the discharge roller conveyor rotate in the same direction. The gypsum board guard is fed from the feed roller conveyor and conveyed to the discharge roller conveyor for discharge. The connection between the feed roller conveyor and the discharge roller conveyor forms a connection area. Multiple lower cutting blades are equidistantly arranged at the lower part of the connecting area along the conveying direction of the gypsum board guard, and the cutting surface of each lower cutting blade is set directly opposite to the conveying direction of the gypsum board guard. The upper cutting blades are arranged at equal intervals along the vertical conveying direction of the gypsum board guard on the upper part of the connecting area. The cutting surface of each upper cutting blade is set directly opposite to the conveying direction of the gypsum board guard. The upper cutting blades and the lower cutting blades are arranged in a one-to-one correspondence, and the bottom of the upper cutting blade abuts against the top of the corresponding lower cutting blade. Indentation blades are provided at equal intervals on the upper part of the connecting area, and the indentation blades are arranged alternately with the upper cutting blades. The number of indentation blades is equal to the number of pre-cut pieces of gypsum board guardrail. The feed roller conveyor pushes the gypsum board guard to the connecting area and drives it to gradually pass through the abutment between the upper cutting blade and the lower cutting blade. Multiple sets of upper and lower cutting blades simultaneously cut the gypsum board guard into multiple pieces, while each indentation blade scratches the upper surface of the corresponding piece of gypsum board guard.

[0007] The friction between the feed roller conveyor and the gypsum board guard is set such that no relative sliding occurs between them during the cutting and scratching process of the gypsum board guard.

[0008] Furthermore, a first mounting shaft is fixedly installed at the lower part of the connecting area along the conveying direction perpendicular to the gypsum board guard, and the lower cutting blade is equidistantly sleeved on the first mounting shaft.

[0009] Furthermore, a second mounting shaft is fixedly provided on the upper part of the connecting area along the conveying direction perpendicular to the gypsum board guard plate, and the upper cutting blade is equidistantly sleeved on the second mounting shaft; Furthermore, the indentation blades are equidistantly sleeved on the second mounting shaft, and the indentation blades and the upper cutting blades are arranged alternately on the second mounting shaft.

[0010] Furthermore, multiple support wheels are equidistantly sleeved on the first mounting shaft, and the support wheels are arranged in a one-to-one correspondence with the indentation blade. The support wheels are used to provide support for the gypsum board guardrail that passes through.

[0011] Furthermore, it also includes a frame, with the two ends of the first fixed shaft respectively fixedly installed on the inner walls of both sides of the frame.

[0012] Furthermore, a support plate frame is installed on the top of both sides of the frame, and the two ends of the second mounting shaft are respectively fixedly installed on the inner sidewalls of the two support plate frames.

[0013] Furthermore, multiple fixing sleeves are equidistantly installed on the top of both sides of the frame along the transport direction of the gypsum board guardrail. A protective shell is fixedly installed on the outer wall of the frame along the side parallel to the transport direction of the gypsum board guard.

[0014] Furthermore, a transmission chain is installed along the length of the protective shell, and a bearing is fixedly installed in each of the fixed sleeves; The same end of each roller in the conveyor roller track passes through the bearing built into the fixed locking sleeve on the same side and extends into the protective shell to form an extension. A transmission gear is assembled at the end of each extension, and the transmission chain is sequentially sleeved on each transmission gear. The other end of each roller extends through the bearing housed in the fixed locking sleeve on the other side and is fixedly connected to the inner ring of the bearing.

[0015] Furthermore, it also includes a drive motor, the drive end of which is equipped with a drive gear; The end of the roller at one end of the conveyor roller track is coaxially connected to a driven gear, and a drive chain is sleeved on the drive gear and the driven gear. The drive motor drives the drive gear to rotate, the drive gear drives the drive chain and the driven gear to rotate, the driven gear drives the transmission gear and the transmission chain connected to it on the same axis to rotate, and the transmission chain drives each of the transmission gears and the roller to rotate.

[0016] Furthermore, a protective cover is fixedly installed between the two support plates, the protective cover being used to cover the lower cutting blade, the upper cutting blade, and the indentation blade.

[0017] Compared with the prior art, the present invention has the following advantages: This invention integrates upper and lower cutting blades in a one-to-one correspondence on a conveyor roller. The conveyor roller pushes the gypsum board panel and gradually passes through the contact point between the upper and lower cutting blades, where the upper and lower cutting blades cut the gypsum board panel. The cutting is completed by the shearing action of the blades on the gypsum board panel, which can significantly reduce the amount of gypsum dust generated. By simultaneously setting indentation blades in the connection area, the gypsum board panel is simultaneously scratched during the cutting process, eliminating the need for step-by-step operations and simplifying the operation process.

[0021] 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.

[0022] like Figure 1 , Figure 2 As shown, the present invention provides a cutting device for gypsum board cladding, comprising: The conveyor roller conveyor 1 has a feed roller conveyor 101 and a discharge roller conveyor 102 connected front and rear. The feed roller conveyor 101 and the discharge roller conveyor 102 rotate in the same direction. The gypsum board guard plate is fed from the feed roller conveyor 101 and conveyed to the discharge roller conveyor 102 for discharge. The connection area 103 is formed at the connection between the feed roller conveyor 101 and the discharge roller conveyor 102. Multiple lower cutting blades 2 are equidistantly arranged in the lower part of the connecting area 103 along the conveying direction perpendicular to the gypsum board guard plate. The cutting surface of each lower cutting blade 2 is set directly opposite to the conveying direction of the gypsum board guard plate. The upper cutting blade 3 is arranged at equal intervals along the conveying direction of the gypsum board guard plate in the upper part of the connecting area 103. The cutting surface of each upper cutting blade 3 is set directly opposite to the conveying direction of the gypsum board guard plate. The upper cutting blade 3 and the lower cutting blade 2 are arranged one-to-one, and the bottom of the upper cutting blade 3 abuts against the top of the corresponding lower cutting blade 2. Indentation blades 4 are provided at equal intervals in the upper part of the connecting area 103, and the indentation blades 4 are staggered with the upper cutting blades 3. The number of indentation blades 4 is equal to the number of pre-cut pieces of gypsum board guardrail. The feed roller conveyor 101 pushes the gypsum board guard to the connecting area 103 and drives it to gradually pass through the abutment between the upper cutting blade 3 and the lower cutting blade 2. Multiple sets of upper cutting blades 3 and lower cutting blades 2 simultaneously cut the gypsum board guard into multiple pieces. At the same time, each indentation blade 4 scratches the upper surface of the corresponding piece of gypsum board guard.

[0023] The friction between the feed roller conveyor 101 and the gypsum board guard is set such that no relative sliding occurs between the feed roller conveyor 101 and the gypsum board guard during the cutting and scratching process.

[0024] This invention integrates upper cutting blades 3 and lower cutting blades 2 in a one-to-one correspondence on the conveyor roller 1. The conveyor roller 1 pushes the gypsum board guard plate and gradually passes through the contact point between the upper cutting blades 3 and lower cutting blades 2, whereby the upper cutting blades 3 and lower cutting blades 2 cut the gypsum board guard plate. The cutting is completed by the shearing action of the blades on the gypsum board guard plate, which can significantly reduce the amount of gypsum dust generated. By simultaneously setting an indentation blade 4 in the connection area 103, the gypsum board guard plate can be scratched simultaneously during the cutting process, eliminating the need for step-by-step operations and simplifying the operation process.

[0025] Furthermore, by using the upper cutting blade 3 and the lower cutting blade 2 in combination to cut the gypsum board lining, compared with the method of sawing the gypsum board lining with a high-speed saw, the safety risks during the operation can be effectively reduced and the safety of the operation can be improved.

[0026] This embodiment provides a cutting device for gypsum board panels, mainly targeting the integrated cutting and indentation technology of gypsum board panels.

[0027] Specifically, the gypsum board guards to be processed are placed on the feeding roller conveyor 101. The feeding roller conveyor 101 and the discharging roller conveyor 102 rotate in the same direction. The gypsum board guards are smoothly conveyed by the preset friction force. When the gypsum board guards are pushed to the connecting area 103 between the feeding roller conveyor 101 and the discharging roller conveyor 102, they gradually pass between the corresponding upper cutting blades 3 and lower cutting blades 2. Multiple pieces are cut simultaneously through the shearing action of the blades. During this process, the staggered indentation blades 4 act synchronously on the upper surface of the corresponding pieces of guards, and the indentation is completed during the transportation of the gypsum board guards. After processing, the cut and indented gypsum board guards continue to be conveyed to the unloading end by the discharging roller conveyor 102, realizing continuous processing.

[0028] Through experiments, it was found that the feed roller conveyor 101 and the gypsum board guard plate can avoid relative sliding under the reaction force of the gypsum board guard plate during cutting and scratching. That is, the friction between the feed roller conveyor 101 and the gypsum board guard plate can push the gypsum board guard plate to complete the cutting and scratching process.

[0029] The upper cutting blade 3 cuts into the top of the gypsum board panel, and the lower cutting blade 2 cuts into the bottom of the gypsum board panel. The two blades are in abutting fit, which can achieve a complete cut in the thickness direction of the gypsum board panel. like Figure 2 As shown, the two adjacent sets of corresponding upper cutting blades 3 and lower cutting blades 2 are cut to form a gypsum board panel cutting block. The denting blade 4 and the upper cutting blade 3 are arranged in an alternating pattern, so that the denting blade 4 corresponds to each gypsum board panel block, ensuring that each gypsum board panel after cutting can be scratched simultaneously.

[0030] In order to fix multiple lower cutting blades 2, a first mounting shaft 5 is fixedly installed in the lower part of the connecting area 103 along the conveying direction perpendicular to the gypsum board guard plate, and the lower cutting blades 2 are equidistantly sleeved on the first mounting shaft 5.

[0031] In order to fix multiple upper cutting blades 3 and indentation blades 4, a second mounting shaft 6 is fixedly installed in the upper part of the connection area 103 along the conveying direction perpendicular to the gypsum board guard plate, and the upper cutting blades 3 are equidistantly sleeved on the second mounting shaft 6. Furthermore, the indentation blades 4 are equidistantly mounted on the second mounting shaft 6, and the indentation blades 4 and the upper cutting blades 3 are arranged alternately on the second mounting shaft 6.

[0032] Multiple support wheels 7 are also equidistantly sleeved on the first mounting shaft 5. The support wheels 7 are arranged in a one-to-one correspondence with the indentation blades 4. The support wheels 7 are used to provide support for the gypsum board guardrails that pass through.

[0033] The support wheel 7 is used to support the passing gypsum board panel, ensuring that the gypsum board panel is subjected to balanced force and does not deform when the indentation blade 4 scratches, thereby ensuring uniform scratch depth and ultimately achieving that each slit gypsum board panel can be scratched synchronously and with high quality.

[0034] In order to fix the first mounting shaft 5, a frame 8 is also included, and the two ends of the first mounting shaft are respectively fixedly installed on the inner walls of the two sides of the frame 8.

[0035] The upper cutting blade 3 is positioned above the lower cutting blade 2. In order to fix the second mounting shaft 6 above the first mounting shaft 5, a support plate 9 is installed on the top of both sides of the frame 8. The two ends of the second mounting shaft 6 are respectively fixedly installed on the inner sidewalls of the two support plate 9. The support plate 9 provides a certain installation height for the second mounting shaft 6, so that the second mounting shaft 6 is located directly above the first mounting shaft 5, thereby ensuring that the upper cutting blade 3 and the lower cutting blade 2 are vertically aligned and appropriately matched.

[0036] like Figure 1 , Figure 3 , Figure 6 As shown, in order to drive the conveyor roller 1 to rotate, the present invention also designs to install the conveyor roller 1 on the frame 8 and additionally sets up a power unit. The specific installation method of the conveyor roller 1 is as follows: Multiple fixing sleeves 10 are installed at equal intervals on the top of both sides of the frame 8, which are parallel to the transport direction of the gypsum board guard. A protective shell 11 is fixedly installed on the outer wall of the frame 8 along the side parallel to the transport direction of the gypsum board guard.

[0037] A transmission chain 12 is installed along its length inside the protective shell 11, and a bearing 13 is fixedly installed in each fixed sleeve 10. At the same end of each roller 15 in the conveyor roller 1, it passes through the bearing 13 built into the fixed locking sleeve on the same side and extends into the protective shell 11 to form an extension 14. A transmission gear 16 is assembled at the end of each extension 14, and the transmission chain 12 is sequentially sleeved on each transmission gear 16. The other end of each roller 15 passes through the bearing 13 built into the fixed locking sleeve on the other side and is fixedly connected to the inner ring of the bearing 13.

[0038] The length of the frame 8 matches the length of the conveyor roller 1. Each roller 15 in the conveyor roller 1 is arranged laterally (i.e., the roller 15 is arranged parallel to the first mounting shaft 5 and the second mounting shaft 6). One end of each roller 15 in the conveyor roller 1 on the same side passes through the bearing 13 on the same side of the frame 8 and continues to extend into the protective shell 11 to form an extension 14. A transmission gear 16 is installed at the end of each extension 14. The transmission gear 16 is meshed with the transmission chain 12. The other end of each roller 15 is fixedly connected to the inner ring of the bearing 13 on the other side. By driving the transmission chain 12 to rotate through the power device, each roller 15 can be rotated.

[0039] The feed roller conveyor 101 and the discharge roller conveyor 102 are divided by a connecting area 103, and there is no roller 15 structure in the connecting area 103.

[0040] like Figure 1 , Figure 5 As shown, in order to provide power to the transmission chain 12, a drive motor 17 is also included, and a drive gear 18 is installed on the drive end of the drive motor 17. The end of the roller 15 at one end of the conveyor roller 1 is also coaxially connected to a driven gear 19, and a drive chain 20 is sleeved on the drive gear 18 and the driven gear 19. The drive motor 17 drives the drive gear 18 to rotate, the drive gear 18 drives the drive chain 20 and the driven gear 19 to rotate, the driven gear 19 drives the transmission gear 16 and the transmission chain 12 connected to it to rotate, and the transmission chain 12 drives each transmission gear 16 and roller 15 to rotate.

[0041] In other words, the feed roller conveyor 101 and the discharge roller conveyor 102 are driven by the same drive device.

[0042] like Figure 4 As shown, a protective cover 21 is also fixedly installed between the two support plates 9. The protective cover 21 is used to cover the lower cutting blade 2, the upper cutting blade 3 and the indentation blade 4.

[0043] The protective cover 21 isolates the cutting components, which can prevent accidental injury from limb contact during operation, and prevent plaster chips and dust generated during the cutting process from splashing and spreading, further ensuring a pollution-free working environment.

[0044] The operation process of this device is as follows: The gypsum board guard to be processed is placed stably on the feeding roller conveyor 101. The gypsum board guard is manually positioned upright with its edges parallel to the conveying direction of the roller conveyor. The feeding roller conveyor 101 conveys the gypsum board guard forward. When the gypsum board guard is conveyed to the connection area 103 between the feeding roller conveyor 101 and the discharge roller conveyor 102, the gypsum board guard continues to be pushed forward by the friction between the feeding roller conveyor 101 and the guard. The upper cutting blade 3 cuts into the gypsum board guard from the top, and the lower cutting blade 2 cuts into the gypsum board guard from the bottom. The two cut into each other to achieve a complete cut in the thickness direction of the gypsum board guard. During this process, the indentation blades 4, which are arranged alternately with the upper cutting blade 3, act synchronously on the upper surface of the corresponding section of the guard. At the same time, the support wheel 7 on the first mounting shaft 5 provides stable support for the corresponding position at the bottom of the gypsum board guard. After the cutting and indentation are completed synchronously, the cut gypsum board guard is conveyed to the unloading end by the discharge roller conveyor 102.

[0045] 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.
