Description

Technical Field

[0001] The invention belongs to the technical field of billboard production, and in particular relates to a cutting auxiliary device for billboard production. Background Art

[0002] Billboards are usually made of metal or plastic. Since the sizes and volumes of billboards are different, during the manufacturing process of billboards, it is usually necessary to cut the sides or other positions to adjust them to the appropriate size. For this purpose, a cutting auxiliary device is needed to assist the cutting process. Conventional cutting devices are mainly made of a workbench and a high-speed rotating cutting disk.

[0003] When using a conventional cutting auxiliary device, the billboard to be cut is usually placed on the workbench, and the end to be cut is placed on one end of the cutting disk. The billboard is pressed tightly by the other hand and pushed horizontally to achieve the cutting process. This cutting process is limited by the strength and precision of the human hand, which can easily lead to deviation during cutting and affect the cutting quality. At the same time, the entire cutting disk is exposed during cutting, which poses certain safety hazards.

[0004] At the same time, during the cutting process, the exposure of the blade will cause cutting debris to splash, and the splashing debris has certain safety hazards, and the generated debris will adhere to the cutting disc. Long-term cutting will cause the cutting disc to wear, which will significantly affect the cutting quality, and improvement is urgently needed. Summary of the invention

[0007] Before cutting the billboard, the billboard can be placed directly above the workbench and directly below the pressing guide assembly. At the same time, the end of the billboard to be cut must be placed at one end of the protective cover to ensure that the billboard can be displaced along the rotation direction of the cutting disc;

[0008] In the initial state, that is, when the linkage assembly is also in the initial state, the protective cover is located directly above the cutting disc, and the rubber sleeve at the bottom does not contact the top of the billboard. At the same time, the clamping guide assembly does not contact the top of the billboard. At this time, the chip box is located directly below the chip box and is not movably engaged with the bottom of the chip box.

[0009] As a further technical solution of the present invention, lateral guide rails are installed on the front and rear sides of the right end of the workbench, upper guide blocks are installed on the front and rear sides of the right end of the protective cover, and lower guide blocks are installed on the front and rear sides of the right end of the chip collection box.

[0010] As a further technical solution of the present invention, the upper guide block and the lower guide block are movably connected to the upper and lower ends of the inner side of the lateral guide rail respectively, and when the distance between the protective cover and the chip box is the minimum, the bottom end of the rubber sleeve contacts the top of the billboard, and the top of the chip box is sleeved under the chip box.

[0011] When cutting, the clamping guide assembly and the protective cover can be moved toward the billboard under the action of the linkage assembly until they contact the top of the billboard. At the same time, the chip box also moves toward the bottom of the chip box until the top of the chip box and the bottom of the chip box are engaged with each other, completing the fixing process.

[0012] As a further technical solution of the present invention, the linkage assembly includes a three-way valve, one side of the three-way valve is connected to the right side of the chip collection box, the top end of the three-way valve is connected to the cleaning assembly, the bottom end of the three-way valve is connected to the external air pump, and the right end of the three-way valve is fixedly connected to an air storage pipe.

[0013] As a further technical solution of the present invention, the internal movable sleeve of the air storage pipe is connected with a piston plate, and the piston plate is displaced left and right relative to the air storage pipe. The end of the air storage pipe away from the three-way valve is fixedly connected to a piston rod located inside the air storage pipe, and the piston rod passes through the right end of the three-way valve and is fixedly connected to the movable plate.

[0014] As a further technical solution of the present invention, the upper and lower ends of the inner side of the movable plate are fixedly connected with a first fixed seat, the end of the first fixed seat away from the movable plate is movably connected to a connecting rod through a rotating shaft, the end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat through a rotating shaft, the internal movable sleeve of the piston rod is connected to a limiting spring, and the left and right ends of the limiting spring are respectively connected to one end of the gas storage pipe and one end of the piston plate.

[0015] When cutting one side of the billboard, the external air pump can be turned on to input high-pressure gas to the bottom end of the linkage assembly. At this time, the high-pressure gas enters the interior of the three-way valve and is input into the interior of the gas storage pipe through the right end of the three-way valve. At this time, the high-pressure air can exert a force on the piston plate, causing the piston plate to move to the right. At this time, the limit spring can be compressed and drive the piston plate and the piston rod to move to the right until the movable plate is pushed to move to the right. At this time, the two connecting rods are deflected, that is, the two connecting rods move closer to the middle, and the angle between the two decreases. A pulling force is applied to the upper and lower second fixing seats, and the two second fixing seats move closer to each other.

[0016] At this time, the upper guide block and the lower guide block can approach each other under the guidance of the lateral guide rail, driving the protective cover and the rubber sleeve to move downward, and the chip box to move upward until the bottom end of the rubber sleeve contacts the top of the billboard, and the protective cover completely covers the outer side of the cutting disc, completing the protection process, and the top of the chip box and the bottom of the chip box are engaged with each other.

[0017] By utilizing the high-pressure gas input from the outside when cutting the billboard, as well as the protective cover located above the cutting disc and the chip box located below the chip box, and cooperating with the structural design of the linkage component, the device can automatically realize the protection process of the cutting disc when the cutting starts, and can automatically release the protection when the cutting is not in progress. The whole process is completed automatically without manual control, which can effectively reduce the safety hazards during cutting, will not interfere with the maintenance of the device, and improve the safety of the device.

[0018] As a further technical solution of the present invention, the cleaning assembly includes an air supply pipe, the bottom end of the air supply pipe is connected to the top of the three-way valve, the top of the air supply pipe is fixedly connected to an air collecting box, the bottom end of the air collecting box is connected to the top of the protective cover, the middle part of the air collecting box is movably connected to a main shaft, the outer side surface of the main shaft is fixedly sleeved with an impeller located inside the air collecting box, and the left end of the main shaft is connected to a clamping guide assembly.

[0019] At the same time, during the cutting process of the billboard, the debris generated by the cutting will be blocked by the protective cover on the outer side of the cutting disk. At the same time, the compressed air entering the three-way valve can be discharged through the air pipe and enter the interior of the air collecting box through the air pipe. At this time, the compressed air can drive the impeller to rotate and drive the main shaft to rotate. The compressed air can be discharged through the bottom of the air collecting box and enter the interior of the protective cover to blow the cutting disk, and discharge the debris adhered to the cutting disk, so that it enters the interior of the chip collecting box and is finally collected through the chip collecting box. When the cutting is completed, the chip collecting box can be separated from the chip collecting box by resetting the device. At this time, the chip collecting box can be dumped to complete the automatic cleaning and collection process of the entire debris.

[0020] By utilizing the compressed air input during the billboard cutting process and directly applying the compressed air to the cleaning component, and coordinating with the automatic downward movement of the protective cover during billboard cutting and the automatic upward movement of the chip box, debris can be blocked during cutting. At the same time, the airflow exported by the cleaning component can quickly remove the debris to avoid adhesion, and the debris can be collected by the chip box to reduce the impact on the cutting disc. The entire process is still completed automatically, which can significantly improve the cutting quality.

[0021] As a further technical solution of the present invention, the clamping guide assembly includes a pressing plate located directly above the workbench, an extension plate is installed on the right end of the pressing plate, the extension plate is connected to the left side of the protective cover, a through slot is opened in the middle of the pressing plate and mounting frames are installed on the left and right sides of the through slot, a guide wheel located inside the through slot is movably connected between the two mounting frames through a rotating shaft, and the bottom end of the guide wheel protrudes from the bottom end of the through slot.

[0022] As a further technical solution of the present invention, a second transmission shaft is fixedly installed at one end of the middle part of the guide wheel, a first transmission shaft is provided above the second transmission shaft, an extension shaft is fixedly installed at the right end of the first transmission shaft, and the right end of the extension shaft is connected to the left end of the main shaft.

[0023] As a further technical solution of the present invention, a synchronous belt is movably sleeved on the outer side of the second transmission shaft, and the other end of the synchronous belt is movably sleeved on the outer side of the first transmission shaft. The first transmission shaft is transmission-connected to the second transmission shaft through the synchronous belt.

[0024] When cutting the billboard, the downward displacement of the protective cover can synchronously drive the extension plate and the pressure plate to move downward, and drive the guide wheel to move downward until the bottom end of the guide wheel contacts the top of the billboard. At this time, the top of the billboard can be clamped and limited, and the motor can be turned on to drive the cutting disk to rotate. Because the extension shaft can be driven to rotate under the driving action of the cleaning component, the first transmission shaft rotates accordingly, and drives the second transmission shaft to rotate through the synchronous belt, and finally realizes the rotation of the guide wheel. At this time, the guide wheel can drive the billboard to translate by friction, that is, drive the billboard to translate relative to the cutting disk to complete the guidance, and cooperate with the rotation of the cutting disk to complete the cutting process of the side of the billboard.

[0025] By utilizing the compressed air input when cutting the billboard to achieve the downward movement of the pressing guide assembly, while completing the pressing of the billboard, the input air can also be used to drive the guide wheel to rotate, thereby realizing automatic guiding of the billboard. The entire process is completed automatically, avoiding the process of manual pressing and translation of traditional devices, effectively avoiding offset during cutting, and automatically releasing the restriction after cutting, significantly improving the quality of the billboard after cutting.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1. The present invention utilizes the compressed air input when cutting the billboard to realize the downward movement of the pressing guide assembly. While completing the pressing of the billboard, the input air can also be used to drive the guide wheel to rotate, thereby realizing automatic guiding of the billboard. The whole process is completed automatically, avoiding the process of manual pressing and translation of traditional devices, effectively avoiding deviation during cutting, and automatically releasing the restriction after cutting, thereby significantly improving the quality of the billboard after cutting.

[0028] 2. The present invention utilizes the compressed air input during the billboard cutting process and directly applies the compressed air to the cleaning component, and cooperates with the automatic downward movement of the protective cover during the billboard cutting, and the automatic upward movement of the chip box to achieve the blocking of debris during cutting. At the same time, the debris can be quickly removed by the airflow exported by the cleaning component to avoid adhesion, and collected by the chip box to reduce the impact on the cutting disk. The whole process is still completed automatically, which can significantly improve the cutting quality.

[0029] 3. The present invention utilizes the high-pressure gas input from the outside when cutting the billboard, as well as the protective cover located above the cutting disc and the chip box located below the chip box, in conjunction with the structural design of the linkage assembly. This allows the device to automatically protect the cutting disc when the cutting begins, and automatically release the protection when no cutting is performed. The entire process is completed automatically without manual control, which can effectively reduce safety hazards during cutting, will not interfere with device maintenance, and improves the safety of the device.

[0046] When cutting one side of the billboard, the external air pump can be turned on to input high-pressure gas to the bottom end of the linkage assembly 14. At this time, the high-pressure gas enters the interior of the three-way valve 141 and is input into the interior of the gas storage pipe 142 through the right end of the three-way valve 141. At this time, the high-pressure air can exert a force on the piston plate 143, causing the piston plate 143 to move to the right. At this time, the limit spring 145 can be compressed and drive the piston plate 143 and the piston rod 144 to move to the right until the movable plate 146 is pushed to move to the right. At this time, the two connecting rods 149 are deflected, that is, the two connecting rods 149 move closer to the middle, and the angle between the two decreases, and a pulling force is applied to the upper and lower second fixing seats 148, so that the two second fixing seats 148 move relatively closer.

At this time, the top of the billboard can be clamped and limited, and the motor 5 can be turned on to drive the cutting disk 6 to rotate.

At this time, the guide wheel 154 can drive the billboard to translate by friction, that is, drive the billboard to translate relative to the cutting disk 6 to complete the guidance, and cooperate with the rotation of the cutting disk 6 to complete the cutting process of the side of the billboard.

[0054] By utilizing the compressed air input when cutting the billboard to achieve the downward movement of the pressing guide assembly 15, while completing the pressing of the billboard, the input air can also be used to drive the guide wheel 154 to rotate, thereby realizing automatic guiding of the billboard. The entire process is completed automatically, avoiding the process of manual pressing and translation of traditional devices, effectively avoiding offset during cutting, and automatically releasing the restriction after cutting, thereby significantly improving the quality of the billboard after cutting.

[0055] Working principle and usage process:

[0056] Before cutting the billboard, the billboard can be placed directly above the workbench 1 and directly below the pressing guide assembly 15, and the end of the billboard to be cut needs to be placed at one end of the protective cover 11 to ensure that the billboard can be displaced along the rotation direction of the cutting disc 6;

[0057] In the initial state, that is, when the linkage assembly 14 is also in the initial state, the protective cover 11 is located directly above the cutting disc 6, and the rubber sleeve 12 at the bottom does not contact the top of the billboard, and the pressing guide assembly 15 does not contact the top of the billboard, and at this time, the chip box 7 is located directly below the chip box 3 and is not movably engaged with the bottom of the chip box 3;

[0058] When cutting, the pressing guide assembly 15 and the protective cover 11 can be moved toward the billboard under the action of the linkage assembly 14 until they are in contact with the top of the billboard, and at the same time, the chip box 7 is also moved toward the bottom of the chip box 3 until the top of the chip box 7 and the bottom of the chip box 3 are engaged with each other, completing the fixing process;

[0059] When cutting one side of the billboard, the external air pump can be turned on to input high-pressure gas to the bottom end of the linkage assembly 14. At this time, the high-pressure gas enters the interior of the three-way valve 141 and is input into the interior of the gas storage pipe 142 through the right end of the three-way valve 141. At this time, the high-pressure air can exert a force on the piston plate 143, causing the piston plate 143 to move to the right. At this time, the limit spring 145 can be compressed and drive the piston plate 143 and the piston rod 144 to move to the right until the movable plate 146 is pushed to move to the right. At this time, the two connecting rods 149 are deflected, that is, the two connecting rods 149 move closer to the middle, and the angle between the two decreases, and a pulling force is applied to the upper and lower second fixing seats 148, so that the two second fixing seats 148 move relatively closer.

[0060] At this time, the upper guide block 9 and the lower guide block 10 can approach each other under the guidance of the lateral guide rail 8, driving the protective cover 11 and the rubber sleeve 12 to move downward, and the chip collecting box 7 to move upward until the bottom end of the rubber sleeve 12 contacts the top end of the billboard, and the protective cover 11 completely covers the outer side of the cutting disc 6, completing the protection process, and the top end of the chip collecting box 7 and the bottom end of the chip collecting box 3 are mutually engaged;

[0061] When cutting the billboard, the downward displacement of the protective cover 11 can synchronously drive the extension plate 152 and the pressure plate 151 to move downward, and drive the guide wheel 154 to move downward until the bottom end of the guide wheel 154 contacts the top of the billboard. At this time, the top of the billboard can be pressed and limited, and the motor 5 can be turned on to drive the cutting disk 6 to rotate. Since the extension shaft 155 can be driven to rotate under the driving action of the cleaning component 13, the first transmission shaft 156 rotates accordingly, and drives the second transmission shaft 157 to rotate through the synchronous belt 158, and finally realizes the rotation of the guide wheel 154. At this time, the guide wheel 154 can drive the billboard to translate by friction, that is, drive the billboard to translate relative to the cutting disk 6 to complete the guidance, and cooperate with the rotation of the cutting disk 6 to complete the cutting process of the side of the billboard;

[0062] At the same time, during the cutting process of the billboard, the debris generated by the cutting will be blocked by the protective cover 11 located on the outer side of the cutting disk 6. At the same time, the compressed air entering the three-way valve 141 can be discharged through the air pipe 131 and enter the interior of the air collecting box 132 through the air pipe 131. At this time, the compressed air can drive the impeller 134 to rotate and drive the main shaft 133 to rotate. The compressed air can be discharged through the bottom end of the air collecting box 132 and enter the interior of the protective cover 11 to blow the cutting disk 6, and discharge the debris adhered to the cutting disk 6, so that it enters the interior of the chip collecting box 3 and is finally collected through the chip collecting box 7. When the cutting is completed, the chip collecting box 7 can be separated from the chip collecting box 3 by resetting the device. At this time, the chip collecting box 7 can be dumped to complete the automatic cleaning and collection process of the entire debris.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
