Description

Technical Field

[0001] This invention relates to the field of cutting technology, specifically to a color-coated steel sheet cutting device and a color-coated steel sheet. Background Technology

[0002] Color-coated steel sheets are products made by using hot-dip galvanized steel sheets, hot-dip aluminum-zinc coated steel sheets, electro-galvanized steel sheets, etc. as substrates, and after surface pretreatment (chemical degreasing and chemical conversion treatment), one or more layers of organic coatings are applied to the surface, followed by baking and curing.

[0003] Some individual business owners, such as decoration and construction workers, usually buy pre-coated steel sheet base materials and then cut them themselves in order to reduce the procurement cost of pre-coated steel sheets. They can also cut them according to the decoration needs.

[0004] However, while existing cutting equipment boasts a high degree of automation, it is not suitable for individual users. To enhance automation, existing cutting equipment employs numerous electronic components, relying on multiple cylinders and motors to achieve automated processing. This necessitates programming, resulting in high initial costs and relatively high maintenance expenses. Furthermore, it requires operators to be familiar with the equipment.

[0005] In addition, this type of cutting equipment is designed for continuous, high-volume cutting needs, so its cost is much higher for individual businesses. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a color-coated steel sheet shearing device and a color-coated steel sheet, solving the problems of high cost and high maintenance costs.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a color-coated steel sheet shearing device, comprising:

[0008] A support platform and a discharge platform located at the end of the support platform;

[0009] Two support components are rotatably mounted on the side of the support platform. A linear guide plate is mounted on the two support components through an adjustment mechanism. A cutting gun is slidably mounted on the linear guide plate along the length direction. A second lead screw is rotatably mounted on the linear guide plate. A first threaded sleeve is fitted on the second lead screw and threaded with it. The first threaded sleeve is fixed to the cutting gun.

[0010] The cutting angle of the carrier is adjusted by the adjustment mechanism, which in turn changes the cutting angle of the cutting gun.

[0011] The support platform and the unloading platform are provided with a gap for cutting, and the length of the gap increases / decreases adaptively with the adjustment mechanism.

[0012] A palletizing mechanism, installed on the unloading platform, is used to unload and palletize the cut color-coated steel sheets.

[0013] A propulsion component is installed on the support platform and connected to the palletizing mechanism through a transmission component. The propulsion component is used to transport the color-coated steel sheet.

[0014] The support platform is provided with multiple guide blocks, and a pressure cap that cooperates with the guide blocks is fixed on the support platform. The pressure cap and the guide blocks cooperate to limit the position of the color-coated plate.

[0015] Furthermore, the adjustment mechanism includes a movable part slidably mounted on the support member, a slider fixed to the linear guide plate is slidably mounted inside the movable part, and a first electric push rod is fixed on the movable part, with the movable rod of the first electric push rod fixed to the slider;

[0017] The support platform is also equipped with a one-way adjustment component for adjusting the length of the gap. The one-way adjustment component is connected to the unloading platform and the support platform, and the one-way adjustment component also cooperates with the follow-up adjustment component.

[0018] Furthermore, the follow-up adjustment assembly includes a rotating seat fixed to the support platform, and the support component is rotatably mounted on the rotating seat;

[0019] A threaded cylinder is rotatably installed inside the bearing component, and a No. 3 lead screw is installed inside the threaded cylinder and threadedly engaged with it. The No. 3 lead screw is fixed to the bottom of the movable component, and a through hole with clearance fit to the No. 3 lead screw is opened at the bottom of the bearing component.

[0020] A second drive shaft is rotatably mounted on the support member. A gear is coaxially fixed on the second drive shaft. The gear meshes with a gear ring fixed on the rotating seat. The gear is also connected to the threaded cylinder through a second bevel gear set.

[0021] Furthermore, the one-way adjustment assembly includes a ratchet coaxially fixed to the rotating shaft of the carrier, and a pawl plate that cooperates with it is slidably mounted on the carrier platform, and the pawl plate is fixed to the unloading platform;

[0022] A connecting block is fixed on the unloading platform, and a guide rod that slides with the connecting block is fixed on the unloading platform. A second spring that is fixed to the connecting block and the unloading platform is sleeved on the guide rod.

[0023] The ratchet plate includes a base plate on which a plurality of equidistant ratchet pawls are elastically hinged, and the ratchet pawls cooperate with the ratchet wheel.

[0024] Furthermore, the palletizing mechanism includes a loading platform slidably mounted on the unloading platform, and each of the four corners of the loading platform is fixed with a No. 2 threaded sleeve.

[0025] Four lead screws of type I that are threaded into the type II threaded sleeve are rotatably mounted on the unloading platform. A type I drive shaft is also rotatably mounted on the unloading platform. The four lead screws of type I and the type I drive shaft are connected by a type I chain.

[0026] A pulling component is fixed on the unloading platform. A limit transmission tube is rotatably installed on the pulling component. The limit transmission tube is connected to the first transmission shaft through the first bevel gear set. The limit transmission tube is connected to the propulsion component.

[0027] Alignment components are installed on the unloading platform.

[0028] Furthermore, the alignment component includes two support blocks fixed to both sides of the unloading platform, a transmission rod rotatably mounted between the two support blocks, multiple sliding sleeves fixed at equal intervals on the transmission rod, a toggle block slidably mounted on the sliding sleeve, a first spring fixed to the end of the toggle block, and the other end of the first spring fixed to the bottom of the inner side of the sliding sleeve.

[0029] The actuating block has an anti-slip part at the end away from the first spring;

[0030] A motor is fixed on the support block, and the output shaft of the motor is coaxially fixed with the transmission rod.

[0031] Furthermore, the propulsion assembly includes two conveying wheels rotatably mounted on both sides of the support platform, and the conveying wheels are connected to the limiting transmission tube via a transmission component;

[0032] A servo motor is fixed on the support platform, and the output shaft of the servo motor is connected to the rotating shaft of the conveyor wheel through a first synchronous belt;

[0033] The conveyor wheel is provided with a deformable rubber layer.

[0034] Furthermore, the transmission component includes a synchronizing rod rotatably mounted on the bottom of the support platform, and intermittent transmission components are installed on both sides of the support platform;

[0035] The intermittent transmission component includes a drive disc fixed coaxially with the conveyor wheel, and a driven disc that cooperates with the drive disc is rotatably mounted on one side of the drive disc. The driven disc is connected to the synchronizing rod through a second synchronous belt.

[0036] A limiting transmission rod is axially slidably installed inside the limiting transmission tube. The limiting transmission rod is connected to the synchronizing rod through a No. 3 bevel gear set, and a connecting piece that is rotatably connected to the synchronizing rod is also rotatably installed on the limiting transmission rod.

[0037] The limiting transmission rod is fixed with a transmission bar, which slides in conjunction with a transmission groove formed on the inner wall of the limiting transmission tube.

[0038] Furthermore, the distance between the transmission rod shaft and the color-coated plate is less than the diameter of the actuating block when it rotates.

[0039] The present invention also provides a color-coated sheet, which is manufactured using the aforementioned color-coated sheet cutting device.

[0040] The present invention has the following beneficial effects:

[0041] I. This color-coated steel sheet cutting device cuts the color-coated steel sheet with a cutting gun, and at the same time adjusts the cutting angle of the cutting gun with the help of an adjustment mechanism to meet the cutting requirements of different angles.

[0042] When adjusting the angle of the cutting gun, the distance between the cutting gun nozzle and the color-coated steel sheet will be adjusted adaptively.

[0043] To reduce costs, the cutting torch is mounted on a carrier via a linear guide plate, and the carrier is directly rotatably mounted on a support platform. Compared to the multi-axis linkage of existing equipment, this method is cheaper and can still meet multi-angle cutting requirements.

[0044] Secondly, the adaptive adjustment of the distance between the cutting gun and the color-coated plate is achieved through a purely mechanical structure. Therefore, there is no need for CNC programming, which reduces the cost of manufacturing, as well as the cost of use and maintenance.

[0045] Second, the color-coated steel sheet cutting device can stack and collect the cut color-coated steel sheets through a stacking mechanism to facilitate subsequent transportation.

[0046] Third, this color-coated steel sheet cutting device can complete the automated cutting work at a fixed angle through the invention. Of course, compared with the existing technology, its degree of automation is lower. However, under the premise of meeting the cutting needs, the purchase and maintenance costs are much lower than the existing technology, so it is more suitable for individual businesses and has stronger practicality.

[0047] Secondly, this invention uses a mechanical mechanism as its core, and its stability and feasibility are superior to existing technologies.

[0048] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0067] 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.

[0068] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0069] The following is based on Figures 1-17 This invention describes a color-coated steel sheet shearing device provided in an embodiment of the invention.

[0070] like Figures 1-17 As shown, an embodiment of the present invention provides a technical solution: a color-coated steel sheet shearing device, including a support platform 1 and a discharge platform 2 disposed at the end of the support platform 1.

[0071] Two support components 4 are rotatably mounted on the side of the support platform 1. A linear guide plate 401 is mounted on the two support components 4 through an adjustment mechanism. A cutting gun 402 is slidably mounted on the linear guide plate 401 along the length direction. A second lead screw 403 is rotatably mounted on the linear guide plate 401. A first threaded sleeve is fitted on the second lead screw 403 and has a threaded engagement with it. The first threaded sleeve is fixed to the cutting gun 402.

[0072] The cutting angle of the carrier 4 is adjusted by the adjustment mechanism, which in turn changes the cutting angle of the cutting gun 402.

[0073] The support platform 1 and the unloading platform 2 are provided with a gap for cutting. The length of the gap increases or decreases adaptively with the adjustment mechanism.

[0074] The stacking mechanism installed on the unloading platform 2 is used to unload and stack the cut color-coated steel sheets.

[0075] The propulsion component is installed on the support platform 1 and connected to the palletizing mechanism through the transmission component. The propulsion component is used to transport the color-coated sheet.

[0076] Multiple guide blocks 102 are provided on the support platform 1, and a pressure cover 101 that cooperates with the guide blocks 102 is fixed on the support platform 1. The color-coated plate is limited by the cooperation between the pressure cover 101 and the guide blocks 102.

[0077] In this embodiment of the invention, a propulsion assembly is used to transport the color-coated steel sheet. Once the color-coated steel sheet is transported to the designated position, the portion to be cut is supported by a stacking mechanism.

[0078] A drive motor is mounted on the linear guide plate 401, and the output shaft of the drive motor is connected to the second lead screw 403 via a belt. When the drive motor runs, its output shaft drives the second lead screw 403 to rotate via the belt. During the rotation of the second lead screw 403, through its threaded engagement with the first threaded sleeve, it drives the first threaded sleeve and the cutting gun 402 to slide at a uniform speed along the length of the linear guide plate 401. At the same time, the cutting gun 402 starts working and cuts the color-coated sheet.

[0079] The tilt angle of the carrier 4 can be adjusted by the adjustment mechanism to achieve cutting of the color-coated sheet at multiple angles.

[0080] The adjustment mechanism includes a movable part 405 that is slidably mounted on the support member 4. A slider 4020 that is fixed to the linear guide plate 401 is slidably mounted inside the movable part 405. A first electric push rod 404 is fixed on the movable part 405. The movable rod of the first electric push rod 404 is fixed to the slider 4020.

[0081] The carrier 4 is also equipped with a follow-up adjustment component for adjusting the distance between the nozzle of the cutting gun 402 and the color-coated plate after the cutting gun 402 is flipped. The follow-up adjustment component is connected to the movable part 405.

[0082] The support platform 1 is also equipped with a one-way adjustment component for adjusting the length of the gap. The one-way adjustment component is connected to the unloading platform 2 and the support platform 1, and the one-way adjustment component also cooperates with the follow-up adjustment component.

[0083] In this embodiment of the invention, two self-locking motors for driving the bearing 4 to rotate are also installed on the unloading platform 2. The self-locking motor is a prior art technology. Its principle is to combine the worm gear and worm with the motor, and drive the bearing 4 to rotate clockwise or counterclockwise through the self-locking motor.

[0084] As another driving method of the present invention, a second electric push rod 4018 is hinged on the support platform 1. The movable rod of the second electric push rod 4018 is rotatably connected to the support member 4. The support member 4 is flipped by the operation of the second electric push rod 4018.

[0085] When the carrier 4 flips, it simultaneously drives the moving part 405, the first electric push rod 404, the linear guide plate 401 and other related components to flip, thereby adjusting the angle of the cutting gun 402 to meet the cutting needs of different angles.

[0086] Among them, such as Figure 16 and Figure 15 As shown, when the carrier 4 rotates counterclockwise, the cutting gun 402 also rotates with the carrier 4. This process causes the head of the cutting gun 402 to become dry with the color-coated plate. Clockwise rotation causes the distance between the head of the cutting gun 402 and the color-coated plate to be too large, resulting in ineffective cutting.

[0087] The present invention achieves this through a follow-up adjustment component. When the cutting gun 402 rotates clockwise or counterclockwise following the carrier 4, the distance between the cutting gun head and the color-coated plate is adjusted to solve the above-mentioned interference problem and the problem of large spacing.

[0088] At the same time, such as Figure 17 As shown, when the cutting gun 402 rotates clockwise, the cutting line of its head is not in the cutting part, resulting in the color-coated plate not being suspended in the air, which leads to problems such as adhesion and incomplete cutting after cutting.

[0089] The present invention solves the above-mentioned problem by using a one-way adjustment component to synchronously adjust the distance between the support platform 1 and the unloading platform 2 as the support member 4 flips, thereby increasing the length of the cutting section.

[0090] The follow-up adjustment assembly includes a rotating seat fixed on the support platform 1, and the support member 4 is rotatably mounted on the rotating seat.

[0091] A threaded cylinder 407 is rotatably installed inside the bearing component 4. A No. 3 lead screw 406 with threaded engagement is installed inside the threaded cylinder 407. The No. 3 lead screw 406 is fixed to the bottom of the movable component 405. A through hole 4021 with clearance engagement with the No. 3 lead screw 406 is opened at the bottom of the bearing component 4.

[0092] A second drive shaft 4019 is rotatably mounted on the bearing 4. A gear 409 is coaxially fixed on the second drive shaft 4019. The gear 409 meshes with a gear ring 4010 fixed on the rotating seat. The gear 409 is also connected to the threaded cylinder 407 through a second bevel gear set 408.

[0093] In this embodiment of the invention, when the carrier 4 flips, it drives the second transmission shaft 4019 to rotate synchronously. When the second transmission shaft 4019 rotates, it rotates around the center of the gear ring 4010. Then, through the meshing of the gear 409 and the gear ring 4010, the gear 409 is driven to rotate on its own axis while rotating around the center of the gear ring 4010.

[0094] When the second drive shaft 4019 rotates, it drives the threaded cylinder 407 to rotate through the second bevel gear set 408. The threaded engagement between the threaded cylinder 407 and the third lead screw 406 drives the movable part 405 to rise or fall along the length of the bearing part 4. The rise or fall of the movable part 405 corresponds to the synchronous movement of the cutting gun 402 and the linear guide plate 401 following the movement of the movable part 405.

[0095] The function of the through hole 4021 is to allow the No. 3 lead screw 406 to descend a greater distance under the premise of compact space inside the bearing member 4, and to prevent the No. 3 lead screw 406 from abutting against the bottom of the inner side of the bearing member 4, thereby locking the No. 3 lead screw 406 and the threaded cylinder 407.

[0096] It should be noted that you should refer to [link / reference]. Figure 15 and Figure 16 When the support member 4 rotates counterclockwise, it corresponds to the rising of the movable member 405; when the support member 4 rotates clockwise, it corresponds to the falling of the movable member 405.

[0097] Of course, the rise or fall here is only a description of the principle in relation to the attached diagram.

[0098] It should also be noted that the second bevel gear set 408 includes two meshing bevel gears, which are coaxially fixed to the second drive shaft 4019 and the threaded cylinder 407, respectively.

[0099] The one-way adjustment assembly includes a ratchet 4011 coaxially fixed on the rotating shaft of the bearing 4, and a ratchet plate 4013 that cooperates with it is slidably installed on the bearing platform 1. The ratchet plate 4013 is fixed to the unloading platform 2.

[0100] A connecting block 4016 is fixed on the unloading platform 2. A guide rod 4017 that slides with the connecting block 4016 is fixed on the unloading platform 2. A second spring 4015 that is fixed to the connecting block 4016 and the unloading platform 2 is sleeved on the guide rod 4017.

[0101] The ratchet plate 4013 includes a base plate on which a plurality of pawls are elastically hinged at equal intervals and engage with the ratchet wheel 4011.

[0102] Linear rollers 202 are installed at the bottom of the unloading platform 2.

[0103] In this embodiment of the invention, when the carrier 4 flips, it drives the ratchet 4011 to rotate. When the ratchet 4011 rotates, it engages with the pawl plate 4013 in one direction, so that when the carrier 4 flips toward the side away from the unloading table 2, the rotation of the ratchet 4011 drives the pawl plate 4013 to slide, thereby driving the unloading table 2 to move toward the direction away from the carrier table 1, thereby increasing the length of the cutting part.

[0104] When the unloading platform 2 moves away from the bearing platform 1, the second spring 4015 is pulled up to store elastic potential energy. When the bearing 4 flips in the opposite direction, it drives the pawl of the pawl plate 4013 to flip, thereby disengaging from the ratchet 4011. At the same time, the elastic potential energy of the second spring 4015 is released, causing the pawl plate 4013 and the unloading platform 2 to move towards the bearing platform 1. Through the reverse rotation of the ratchet 4011 and the release of the elastic potential energy of the second spring 4015, the unloading platform 2 and the pawl plate 4013 return to their initial positions. Figure 12 As shown.

[0105] Since the ratchet plate 4013 and the ratchet 4011 are in a one-way engagement, when the ratchet 4011 rotates in the other direction, the ratchet 4011 and the ratchet plate 4013 do not have a transmission relationship. Of course, during the process of the bearing 4 flipping towards the unloading table 2 and resetting, due to the characteristics of the structure, the unloading table 2 will still be driven to move away from the bearing table 1.

[0106] This embodiment is applicable to follow-up adjustment, that is, automatic adjustment when the carrier 4 is flipped. Therefore, it needs to be adjusted before cutting each batch of raw materials. The corresponding ratchet 4011 is detachable and can be calibrated by disassembling the ratchet 4011.

[0107] Secondly, this invention does not target adjustments during the cutting process, but rather adjustments at a specific angle before cutting, so as to simplify angle adjustment and eliminate the need for experience while reducing manufacturing and usage costs.

[0108] Most existing regulating devices achieve regulation through the coordinated operation of multiple cylinders or multiple motors, and require a series of procedures such as CNC programming. The maintenance cost is also relatively high, making them unsuitable for individual users. Individual users are primarily concerned with the purchase cost of the equipment as well as the cost of use and maintenance. Involving too many electronic components would obviously significantly increase both the purchase and maintenance costs.

[0109] It should also be noted that the ratchet 4011 is equipped with an angle gauge 4012, which works in conjunction with a pointer 4014 fixed on the support platform 1 to facilitate the judgment of the angle.

[0110] The palletizing mechanism includes a loading platform 207 that is slidably mounted on the unloading platform 2. Each of the four corners of the loading platform 207 is fixed with a No. 2 threaded sleeve.

[0111] Four lead screws 201 that are threaded and engaged with the No. 2 threaded sleeve are rotatably mounted on the unloading platform 2. A drive shaft 204 is also rotatably mounted on the unloading platform 2. The four lead screws 201 and the drive shaft 204 are connected by a chain 203.

[0112] A pulling component 206 is fixed on the unloading platform 2. A limit transmission tube 505 is rotatably installed on the pulling component 206. The limit transmission tube 505 is connected to the first drive shaft 204 through the first bevel gear set 205. The limit transmission tube 505 is connected to the propulsion component.

[0113] Alignment components are installed on unloading platform 2.

[0114] In this embodiment of the invention, when the pusher is working, it drives the limit transmission tube 505 to rotate. When the limit transmission tube 505 rotates, it drives the first transmission shaft 204 to rotate through the first bevel gear set 205. When the first transmission shaft 204 rotates, it drives the four first lead screws 201 to rotate synchronously through the first chain 203. The first lead screw 201 drives the loading platform 207 to rise or fall through the threaded engagement between the first lead screw 201 and the second threaded sleeve.

[0115] Each time the propulsion component works, it will drive the No. 1 lead screw 201 to rotate once, thereby driving the material platform 207 to stand upright and descend to one side.

[0116] Each operation of the propulsion component is based on the completion of the cutting. After the cutting is completed, the cut color-coated plate is driven by the alignment component to move to the top of the loading platform 207, and then the loading platform 207 is lowered. By pushing the loading platform 207 down each time, the cut color-coated plates are stacked to facilitate the removal of the color-coated plates in one go.

[0117] The alignment component includes two support blocks 302 fixed on both sides of the unloading platform 2. A transmission rod 3 is rotatably installed between the two support blocks 302. Multiple sliding sleeves 303 are fixed at equal intervals on the transmission rod 3. A toggle block 304 is slidably installed on the sliding sleeve 303. A first spring 305 is fixed to the end of the toggle block 304. The other end of the first spring 305 is fixed to the bottom of the inner side of the sliding sleeve 303.

[0118] An anti-slip part is provided at the end of the toggle block 304 away from the first spring 305.

[0119] A No. 1 motor 301 is fixed on the support block 302, and the output shaft of the No. 1 motor 301 is fixed coaxially with the transmission rod 3.

[0120] In this embodiment of the invention, when motor 301 operates, its output shaft drives the transmission rod 3 to rotate, so that the sliding sleeve 303 is synchronously driven to rotate via the transmission rod 3. Figure 13 As shown, when the sliding sleeve 303 flips, it drives the actuating block 304 to rotate synchronously. After the actuating block 304 rotates to contact the color-coated plate, it continues to rotate. Because the distance between the rotating shaft of the sliding sleeve 303 and the color-coated plate is less than the rotation diameter of the actuating block 304, the actuating block 304 retracts into the sliding sleeve 303, thereby compressing the first spring 305. This allows the first spring 305 to store elastic potential energy, so that when the actuating block 304 retracts into the sliding sleeve 303, it applies a reverse force to the first spring 305. This force applies a pressing force to the color-coated plate when the actuating block 304 rotates and contacts it, increasing the friction between the actuating block 304 and the color-coated plate. Thus, the rotation of the actuating block 304 once drives the color-coated plate to move a certain distance. Figure 14 As shown.

[0121] The propulsion assembly includes two conveyor wheels 502 rotatably mounted on both sides of the support platform 1. The conveyor wheels 502 are connected to the limit transmission rod 506 through a transmission component.

[0122] A servo motor 5 is fixed on the support platform 1. The output shaft of the servo motor 5 is connected to the rotating shaft of the conveyor wheel 502 through the first synchronous belt 501.

[0123] The conveyor wheel 502 is provided with a deformable rubber layer.

[0124] A protective shell 5010 is fixed on the support platform 1 to protect the servo motor 5 and related components.

[0125] In this embodiment of the invention, when the servo motor 5 is working, its output shaft drives the conveyor wheel 502 to rotate through the first synchronous belt 501. When the conveyor wheel 502 rotates, it conveys the color-coated plate on the support platform 1.

[0126] When the conveyor wheel 502 rotates, it also drives the second synchronous belt 504 to rotate through the transmission component.

[0127] The transmission components include a synchronizing rod 507 rotatably mounted on the bottom of the support platform 1, and intermittent transmission components 503 are installed on both sides of the support platform 1.

[0128] The intermittent transmission component 503 includes a drive disc fixed coaxially with the conveyor wheel 502, and a driven disc that is rotatably mounted on one side of the drive disc. The driven disc is connected to the timing rod 507 via a second timing belt 504.

[0129] A limiting transmission rod 506 is axially slidably installed inside the limiting transmission tube 505. The limiting transmission rod 506 is connected to the synchronizing rod 507 through the No. 3 bevel gear set 509. A connecting piece 508 that is rotatably connected to the synchronizing rod 507 is also rotatably installed on the limiting transmission rod 506.

[0130] The limiting transmission rod 506 is fixed with a transmission bar, which slides in conjunction with the transmission groove opened on the inner wall of the limiting transmission tube 505.

[0131] In this embodiment of the invention, when the conveyor wheel 502 rotates, it drives the drive disc to rotate, which in turn drives the driven disc to rotate. The driven disc drives the synchronizing rod 507 to rotate via the second synchronous belt 504. When the synchronizing rod 507 rotates, it drives the limiting transmission rod 506 to rotate via the third bevel gear set 509. The limiting transmission rod 506 drives the limiting transmission tube 505 to rotate via the cooperation of the transmission bar and the transmission groove.

[0132] Among them, the intermittent transmission component 503 is the application of the grooved wheel mechanism in the prior art. When the driving disc rotates one revolution, it drives the driven disc to rotate one-fifth of its original rotation. That is to say, the driving disc rotates five revolutions and drives the driven disc to rotate one revolution, so as to reduce the transmission ratio and achieve high-precision transmission.

[0133] When the unloading platform 2 moves away from the bearing platform 1, it drives the pulling member 206 to move synchronously, so that the pulling member 206 drives the limiting transmission tube 505 to move synchronously. At this time, the limiting transmission tube 505 and the limiting transmission rod 506 are in an axial sliding state. Due to the cooperation of the transmission bar and the transmission groove, the two will not cut off the synchronous rotation when they are axially sliding.

[0134] Gear 409 is used to limit the movement of the limiting transmission rod 506, so that the limiting transmission rod 506 will not move when the limiting transmission tube 505 is moving.

[0135] The distance between the axis of the transmission rod 3 and the color-coated plate is less than the diameter of the actuating block 304 when it rotates.

[0136] In this embodiment of the invention, the diameter of the first spring 305 when it rotates refers to the rotation of the actuating block 304 around the transmission rod 3 as the axis, and the distance from the anti-slip part of the actuating block 304 to the axis of the transmission rod 3 is greater than the distance between the transmission rod 3 and the color-coated plate. This limitation refers to the actuating block 304 when it is retracted into the sliding sleeve 303.

[0137] In summary, the color-coated sheet is conveyed using a propulsion assembly. Once the sheet is conveyed to the designated position, the portion to be cut is supported by a stacking mechanism. The cutting gun 402 then begins to cut the sheet. The tilt angle of the carrier 4 can be adjusted by an adjustment mechanism to achieve cutting at various angles.

[0138] The advantages are as follows:

[0139] 1. By replacing the electronic control system with a mechanical adaptive mechanism (follow-up adjustment component + unidirectional adjustment component), dynamic optimization of cutting parameters can be achieved at low cost.

[0140] 2. The unique power transmission link (push → cut → palletize linkage) reduces the number of drive components.

[0141] 3. Targeted solutions to industry pain points in color-coated sheet cutting (angle interference, cutting adhesion, stacking efficiency).

[0142] The present invention also provides a color-coated sheet, which is manufactured using the aforementioned color-coated sheet cutting device.
