Description

Technical Field

[0001] The invention relates to the technical field of conveying, in particular to a conveying device capable of effectively fixing plywood. Background Art

[0002] Plywood is a board made by rotary cutting logs into large veneers along the direction of the annual rings. After drying and gluing, the boards are assembled and glued together in such a way that the wood grains of adjacent veneer layers are perpendicular to each other. The number of veneer layers is an odd number, generally three to thirteen layers. Common ones are three-ply boards, five-ply boards, and nine-ply boards, which are widely used in life.

[0003] Patent announcement number CN209352264U discloses a plywood conveying device with cooling function, including: a mounting frame, an active roller, a driven roller, an endless belt and a motor, and also includes a cooling mechanism, the cooling mechanism includes an upper blowing assembly for cooling the upper surface of the plywood and a lower blowing assembly for cooling the lower surface of the plywood; the annular array on the annular belt is provided with a plurality of oblique supporting assemblies for tilting the plywood. Through the above manner, the plywood conveying device with cooling function described in the patent, the plywood is tiltedly placed above the endless belt for transmission, and under the action of the blower, air is blown toward the upper surface of the plywood through the upper blowing assembly, and at the same time, air is blown toward the lower surface of the plywood through the lower blowing assembly, thereby improving the cooling effect and heat dissipation efficiency.

[0004] However, the device still has some shortcomings: the device can quickly cool down the plywood, but during the plywood transportation process, due to the vibration or external force interference generated by the operation of mechanical equipment, the stability between the plywood and the conveyor belt is poor. At this time, the plywood is easy to fall from the surface of the conveyor belt to the ground, causing damage to the surface and reducing the appearance integrity and aesthetics. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a conveying device capable of effectively fixing plywood, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a conveying device capable of effectively fixing plywood, comprising a device body, a plurality of circular holes are opened on the outer wall of the device body, a transmission assembly is arranged inside the device body, and the transmission assembly is fixedly connected to the output end of an external motor, a conveyor belt is arranged on the outer wall of the transmission assembly, a blower is arranged on the outer wall of the device body, an air duct is arranged on the side of the blower close to the center of the device body, and the air duct is arranged inside the circular holes on the outer wall of the device body, two hollow plates are fixedly installed on the inner wall of the device body, and a telescopic rod is slidably installed through the two hollow plates close to the center of the device body through a spring, and a U-shaped groove is opened at the telescopic end of the telescopic rod. A rotating wheel is rotatably installed inside the U-shaped groove at the telescopic end of the rod, and a linkage plate is fixedly installed on the outer wall of the telescopic end of the telescopic rod, and a reciprocating screw is rotatably installed on the top of the hollow plate, and a pressure plate is penetrated and slidably installed on the outer wall of the reciprocating screw, and a limit rod is penetrated and slidably installed inside the pressure plate, and the bottom of the limit rod is fixedly installed on the top edge of the hollow plate on the side opposite to the outer wall of the reciprocating screw. Two U-shaped rods are hinged on the vertical surfaces of the outer walls on the left and right sides of the pressure plate through a torsion spring, and the two U-shaped rods are symmetrically distributed around the axis of the pressure plate, and a cylinder is rotatably installed on the circular surface of the outer wall of the bottom of the U-shaped rod, and the motor is started. The rotation of the output end of the motor drives the transmission assembly to rotate, and the transmission assembly drives the conveyor belt when it rotates, and the conveyor belt carries the bonded plywood to The plywood is then conveyed by the double transmission, and the blower is started at this time; when the plywood enters the top of the conveyor belt, the outer wall of the plywood contacts the outer wall of the wheel under the drive of the conveyor belt, and the outer wall of the wheel starts to rotate through the friction between the outer wall of the side of the plywood, converting the friction contact between the two into rolling contact, and the spring causes the wheel to always be close to the outer wall of the plywood, while the telescopic rod limits the wheel, and subsequently when the diameter of the plywood is larger, it will contact the wheel to move toward the inside of the telescopic rod, and the wheel will push the telescopic end of the telescopic rod to move synchronously, and the telescopic end of the telescopic rod will drive the linkage plate to move synchronously, and the telescopic end of the telescopic rod will not be completely retracted into the telescopic rod due to the contact of the linkage plate, but will contact the telescopic rod as a whole to slide toward the inside of the hollow plate, and when the plywood leaves the top of the conveyor belt, The telescopic rod and the rotating wheel are reset by the spring and the telescopic rod pulls the linkage plate to reset; the motor is started, and the output end of the motor drives the reciprocating screw to rotate. When the reciprocating screw rotates, the spiral groove limits the pressure plate and the built-in block of the pressure plate contacts the inner wall of the spiral groove, so that the pressure plate slides up and down along the outer wall of the reciprocating screw. At this time, the limit rod limits the pressure plate, and when the pressure plate moves downward, it drives the U-shaped rod to move synchronously. The U-shaped rod drives the cylinder to move synchronously and the outer wall of the cylinder contacts the top of the plywood to generate a resistance force. At this time, the hinge shaft between the U-shaped rod and the pressure plate starts to rotate, and the U-shaped rod pushes the cylinder to slide along the top of the plywood away from the center of the device body and reset, and the outer wall of the cylinder starts to rotate through the rotational force generated by friction with the top of the plywood, and so on.

[0007] According to the above technical solution, the two hollow plates are symmetrically distributed around the axis of the device body, and a motor is arranged at the bottom of the hollow plates. The bottom of the reciprocating screw rod passes through and is fixedly installed on the top of the motor output end, and the reciprocating screw rod and the telescopic rod are staggered. The cylinder is hollow in design, and a plurality of sliding grooves are provided on the outer wall of the cylinder. A bonding device for tightening the bonding strength during plywood transportation is arranged inside the cylinder.

[0008] According to the above technical solution, the fitting device includes a fixed disk, a convex block, a sliding ring, a plurality of convex ball rods and a plurality of arc plates. The fixed disk is far away from the inside and penetrates and is fixedly installed on the inner wall of the U-shaped rod. The convex block is fixedly installed on the inner wall of the fixed disk on a plane away from the center of the U-shaped rod. The inner wall of the sliding ring penetrates and is slidably installed on the outer wall surface of the U-shaped rod. The left side of the plurality of convex ball rods is equidistant and fixedly installed on the right side of the sliding ring. The concave surfaces of the inner walls of the plurality of arc plates are fixedly installed on the outer wall of the sliding ring. The outer wall of the arc plate is slidably installed in the inner groove of the outer wall of the cylinder. The cylinder is along the outer wall of the U-shaped rod. When rotating, it drives the arc plate to rotate, and when the arc plate rotates, it drives the sliding ring to rotate, and when the sliding ring rotates, it drives the convex ball rod to rotate. When the convex ball rod rotates, its own round surface will resist the convex block on the inner wall of the fixed plate, and the round surface of the convex ball rod contacts the arc surface of the convex block to generate a resistance force. At this time, the convex ball rod pushes the sliding ring to slide left inside the cylinder, and the sliding ring drives the arc plate to slide synchronously along the inside of the cylindrical slide groove. When the convex ball rod no longer resists the convex block, the sliding ring is reset by the elastic force of the spring inside the U-shaped rod, and the sliding ring pulls the arc plate to reset. This reciprocating process enables the arc plate to continuously slide and squeeze the edge of the plywood laterally.

[0009] According to the above technical solution, a spring is arranged between the sliding ring and the inside of the U-shaped rod, the sliding ring is located inside the cylinder, the arc surface of the convex block is located on the arc motion trajectory of the right side of the convex ball rod, a gap is left between the left side of the arc plate and the left side of the outer wall of the cylindrical arc groove, and an anti-pollution device is arranged on the outer side of the bottom of the pressure plate for purifying harmful gases generated when the glue inside the plywood evaporates.

[0010] According to the above technical solution, the bonding device also includes a groove arc block and a plurality of thin plates. The right side of the groove arc block passes through and is fixedly installed on the right side of the inner wall of the sliding ring. The plurality of thin plates are fixedly installed at equal distances on the circular outer wall surface of the U-shaped rod. The edge of the outer wall of the thin plate is located on the movement trajectory of the inner wall of the groove arc block. When the sliding ring rotates, it drives the groove arc block to rotate. When the groove arc block rotates, its own groove continuously contacts the edge of the outer wall of the thin plate to cause bending deformation. When the groove arc block no longer contacts the thin plate, the thin plate will swing back and forth when it is reset by its own toughness, causing the cylinder and the arc plate to shake slightly. Through the above cooperation, the arc plate carries the shaking force when bonding and pressing the plywood, eliminating the bubbles or gaps between the two plates, so that the bonding degree of the mutually bonded parts of the plywood is further improved.

[0011] According to the above technical scheme, the anti-pollution device includes an activated carbon plate and a torsion plate. The inner wall at the top of the activated carbon plate is hinged at the vertical surfaces of the outer walls on the left and right sides of the pressure plate, and a circular groove is provided on the inclined surface of the activated carbon plate close to the center of the device body. The torsion plate is fixedly installed between the inclined surface of the activated carbon plate and the bottom edge of the pressure plate. When the pressure plate moves downward, it drives the activated carbon plate to move synchronously. The inclined surface of the inner wall of the activated carbon plate slides downward along the arc surface at the top of the blower. The activated carbon plate causes its own hinge shaft to rotate through the resistance force between the activated carbon plate and the arc surface at the top of the blower. At the same time, the activated carbon plate pulls the torsion plate to deform synchronously. When the activated carbon plate is reset, it drives the torsion plate to reset, and the displacement amplitude of the activated carbon plate is limited by the torsion plate.

[0012] According to the above technical solution, the anti-pollution device also includes a fixed column, a cam and a plurality of arc blocks. The bottom of the fixed column is fixedly installed at the top center of the device body, the outer wall of the cam is rotatably installed at the concave surface of the top of the fixed column, and the outer wall of the cam is in contact with the circular groove of the activated carbon plate. Several arc blocks are equidistantly installed on the vertical surface of the outer wall of the cam by sliding through springs on one side close to the center of the device body. At the same time, when the circular groove of the activated carbon plate contacts the outer wall of the cam, the friction force causes the cam to generate a rotational force and start to rotate. At this time, the top of the cam fixed column rotates, and when the activated carbon plate moves downward, the cam is caused to rotate counterclockwise, and when the activated carbon plate moves upward, the cam is caused to rotate clockwise. Subsequently, the cam drives the arc block to rotate.

[0013] According to the above technical scheme, the anti-pollution device also includes a plurality of arc blocks, a rotating rod and a resistance ring. The plurality of arc blocks are equidistant from the center side of the cam and fixedly mounted on the side of the arc block close to the center of the cam. The rotating rod is fixedly mounted on the vertical surface of the outer wall of the cam close to the center of the activated carbon plate, and a spiral groove is provided on the outer wall of the rotating rod. The resistance ring penetrates through the inside and is slidably mounted on the outer wall surface of the rotating rod. The arc surface of the arc block is located on the arc surface motion trajectory of the resistance ring. When the cam rotates, it drives the rotating rod to rotate. When the rotating rod rotates, the resistance ring is restricted by the non-self-locking spiral groove on its outer wall, and the internal block of the resistance ring contacts the inner wall of the spiral groove, so that the resistance ring can slide left and right along the outer wall of the rotating rod when the rotating rod rotates counterclockwise and clockwise. When the resistance ring slides, its own arc surface will resist the arc surface of the arc block to move away from the center of the cam. The arc block pushes the arc block to move synchronously, and then the arc block is reset by the elastic force of the spring, and this process repeats.

[0014] The present invention provides a conveying device capable of effectively fixing plywood, which has the following beneficial effects:

[0015] (1) The present invention coordinates the hollow plate, telescopic rod, rotating wheel and linkage plate to ensure that the plywood always maintains good stability during transportation to avoid bumping or falling to the ground, thereby ensuring the appearance integrity and aesthetics of the plywood. At the same time, it can adaptively clamp plywood of different sizes during transportation to improve the scope of application. The reciprocating screw, pressure plate, limit rod, U-shaped rod and cylinder coordinate to enable the outer wall of the cylinder to generate a rotational force through friction with the top of the plywood and start to rotate, so that the plywood is subjected to a top pressure force during stable transportation, thereby avoiding external bumps during transportation, which may cause the unfirmly bonded part of the plywood to move and cause misalignment between the two boards.

[0016] (2) The present invention sets a bonding device, and cooperates with a cylinder, a fixed plate, a convex block, a sliding ring, a convex ball rod and an arc plate, so that the arc plate can perform secondary extrusion bonding on the edge of the plywood, so that the adhesive part between the two boards can be further tightened on the original basis, thereby reducing the possibility of debonding of the plywood in the later stage; through the cooperation of the groove arc block and the thin plate, the arc plate carries a shaking force when bonding and pressing the plywood, which eliminates bubbles or gaps between the two boards, so that the bonding degree of the plywood parts that are bonded to each other is further improved.

[0017] (3) The present invention sets an anti-pollution device, and cooperates with a pressure plate, an activated carbon plate and a twisting plate to enable the activated carbon plate to slide back and forth up and down, thereby accelerating the absorption and purification of harmful gases generated when the glue in the bonding part of the plywood evaporates, thereby preventing the workers from absorbing harmful gases such as formaldehyde during long-term processing and endangering their health; through the cooperation of a fixed column, a cam, an arc block, an arc surface block, a rotating rod and a resistance ring, the arc block is caused to disturb the formaldehyde gas contacting the activated carbon plate when it rotates, so that the formaldehyde gas can evenly and quickly enter the activated carbon plate for purification, thereby preventing the accumulation of harmful gases from polluting the environment; and the activated carbon plate will swing back and forth during the downward movement, further improving the absorption speed and purification efficiency of the formaldehyde gas, so that the activated carbon plate itself can fully participate in the purification process, avoiding uneven absorption and shortening the replacement cycle of the activated carbon plate.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] See also Figure 1-Figure 9One embodiment of the present invention is: a conveying device capable of effectively fixing plywood, comprising a device body 1, a plurality of circular holes are opened on the outer wall of the device body 1, a transmission assembly 2 is arranged inside the device body 1, and the transmission assembly 2 is fixedly connected to the output end of the external motor, a conveyor belt 21 is arranged on the outer wall of the transmission assembly 2, a blower 3 is arranged on the outer wall of the device body 1, a duct 31 is arranged on the side of the blower 3 near the center of the device body 1, and the duct 31 is arranged inside the circular hole on the outer wall of the device body 1, two hollow plates 6 are fixedly installed on the inner wall of the device body 1, and a telescopic rod 7 is penetrated and slidably installed through a spring on the two hollow plates 6 near the center of the device body 1, a U-shaped groove is opened at the telescopic end of the telescopic rod 7, a rotating wheel 8 is rotatably installed inside the U-shaped groove at the telescopic end of the telescopic rod 7 through a spring, a linkage plate 9 is fixedly installed on the outer wall of the telescopic end of the telescopic rod 7, a reciprocating screw 10 is rotatably installed on the top of the hollow plate 6, a pressing plate 11 is penetrated and slidably installed on the outer wall of the reciprocating screw 10, and a limited plate 11 is penetrated and slidably installed inside the pressing plate 11 The positioning rod 12 and the bottom of the limiting rod 12 are fixedly installed at the top edge of the hollow plate 6 on the side opposite to the outer wall of the reciprocating screw rod 10. The vertical surfaces of the outer walls on the left and right sides of the pressure plate 11 are hinged with two U-shaped rods 13 through torsion springs. The two U-shaped rods 13 are symmetrically distributed around the axis of the pressure plate 11. A cylinder 14 is rotatably installed on the circular surface of the outer wall of the bottom of the U-shaped rod 13. The blower 3 blows air through the outer wall of the device body 1 through the air duct 31 to the plywood on the top of the conveyor belt 21 to cool it down, thereby improving the cooling effect and heat dissipation efficiency of the plywood. Through the above cooperation, the plywood is always kept in good stability during transportation to avoid bumping or falling to the ground, thereby ensuring the integrity and aesthetics of the plywood appearance. At the same time, the plywood of different sizes can be stably clamped during transportation to improve the scope of application. Through the above cooperation, the plywood is subjected to the top pressing force during stable transportation, thereby avoiding external bumping during transportation, which causes the unfirmly bonded part of the plywood to move and cause misalignment between the two boards.

[0030] The two hollow plates 6 are symmetrically distributed around the axis of the device body 1, and a motor is arranged at the bottom of the hollow plate 6. The bottom of the reciprocating screw 10 passes through and is fixedly installed on the top of the motor output end, and the reciprocating screw 10 and the telescopic rod 7 are staggered. The cylinder 14 is hollow in design, and a plurality of slide grooves are opened on the outer wall of the cylinder 14. A bonding device 4 is arranged inside the cylinder 14 for tightening the bonding strength during the plywood transportation.

[0031] When in use, the motor is started, and the motor output end rotates to drive the transmission component 2 to rotate. When the transmission component 2 rotates, it drives the conveyor belt 21 to transmit. The conveyor belt 21 reciprocates and transmits the bonded plywood. At this time, the blower 3 is started, and the blower 3 blows air through the air duct 31 through the outer wall of the device body 1 to the plywood on the top of the conveyor belt 21 to cool it down, thereby improving the cooling effect and heat dissipation efficiency of the plywood; when the plywood enters the top of the conveyor belt 21, under the transmission of the conveyor belt 21, the outer wall of the plywood hits the outer wall of the rotating wheel 8, and the outer wall of the rotating wheel 8 starts to rotate due to the friction between the outer wall of the side of the plywood, and the plywood between the two is cooled. The friction contact is converted into rolling contact, and the spring is used to force the rotating wheel 8 to always be close to the outer wall of the plywood. At the same time, the telescopic rod 7 limits the rotating wheel 8. Later, when the diameter of the plywood is larger, it will resist the rotating wheel 8 to move toward the inside of the telescopic rod 7. The rotating wheel 8 pushes the telescopic end of the telescopic rod 7 to move synchronously, and the telescopic end of the telescopic rod 7 drives the interlocking plate 9 to move synchronously. The telescopic end of the telescopic rod 7 is resisted by the interlocking plate 9 and will not be completely retracted into the telescopic rod 7. Instead, it will resist the telescopic rod 7 to slide as a whole toward the inside of the hollow plate 6. When the plywood leaves the top of the conveyor belt 21, the telescopic rod 7 and the rotating wheel 8 are reset by the spring, and the telescopic rod 7 pulls the interlocking plate 9 to reset. The above cooperation ensures that the plywood always maintains good stability during transportation to avoid bumping or falling to the ground, ensures the integrity and aesthetics of the plywood appearance, and at the same time adapts to the stable clamping of plywood of different sizes during transportation, thereby improving the scope of application; the motor is started, and the output end of the motor drives the reciprocating screw 10 to rotate. When the reciprocating screw 10 rotates, the spiral groove limits the pressing plate 11, and the built-in block of the pressing plate 11 contacts the inner wall of the spiral groove, so that the pressing plate 11 slides up and down along the outer wall of the reciprocating screw 10. At this time, the limit rod 12 limits the pressing plate 11, and when the pressing plate 11 moves downward, it drives the U-shaped rod 13 to move synchronously. The U-shaped rod 13 drives the cylinder 14 to move synchronously and the outer wall of the cylinder 14 contacts the top of the plywood to generate a resistance force. At this time, the hinge axis between the U-shaped rod 13 and the pressure plate 11 begins to rotate, and the U-shaped rod 13 pushes the cylinder 14 to slide along the top of the plywood away from the center of the device body 1 and reset, and the outer wall of the cylinder 14 generates a rotational force through friction with the top of the plywood and begins to rotate, and this is repeated. Through the above cooperation, the plywood is subjected to the top pressing force during the stable conveying process, avoiding external bumps during the conveying process, which causes the unfirmly bonded part of the plywood to move and cause misalignment between the two boards.

[0032] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes a laminating device 4;

[0033] The bonding device 4 includes a fixed disk 41, a convex block 42, a sliding ring 43, a plurality of convex ball rods 44 and a plurality of arc plates 45. The fixed disk 41 penetrates away from the interior and is fixedly installed on the inner wall of the U-shaped rod 13. The convex block 42 is fixedly installed on the inner wall of the fixed disk 41 on a plane away from the center of the U-shaped rod 13. The inner wall of the sliding ring 43 penetrates and is slidably installed on the outer wall surface of the U-shaped rod 13. A plurality of convex ball rods 44 are equidistant on the left side and fixedly installed on the right side of the sliding ring 43. The concave surfaces of the inner walls of the plurality of arc plates 45 are fixedly installed on the outer wall of the sliding ring 43. The outer wall of the arc plate 45 is slidably installed inside the sliding groove of the outer wall of the cylinder 14. Through the above cooperation, the arc plate 45 can perform secondary extrusion bonding on the edge of the plywood, so that the adhesive part between the two boards can be further tightened on the original basis, reducing the possibility of debonding of the plywood in the later stage.

[0034] A spring is arranged between the sliding ring 43 and the inside of the U-shaped rod 13, the sliding ring 43 is located inside the cylinder 14, the arc surface of the convex block 42 is located on the arc surface movement trajectory on the right side of the convex ball rod 44, a gap is left between the left side of the arc plate 45 and the left side of the outer wall of the arc groove of the cylinder 14, and an anti-pollution device 5 is arranged on the outside of the bottom of the pressing plate 11 for purifying harmful gases generated when the glue inside the plywood evaporates.

[0035] The bonding device 4 also includes a groove arc block 46 and a plurality of thin plates 47. The right side of the groove arc block 46 penetrates through and is fixedly installed on the right side of the inner wall of the sliding ring 43. The plurality of thin plates 47 are fixedly installed on the circular outer wall surface of the U-shaped rod 13 at equal distances. The edge of the outer wall of the thin plate 47 is located on the movement trajectory of the inner wall of the groove arc block 46. Through the above cooperation, the arc plate 45 carries a shaking force when bonding and pressing the plywood to eliminate bubbles or gaps between the two boards, so that the bonding degree of the mutually bonded parts of the plywood is further improved.

[0036] When in use, the cylinder 14 rotates along the outer wall of the U-shaped rod 13, driving the arc plate 45 to rotate. When the arc plate 45 rotates, it drives the sliding ring 43 to rotate. When the sliding ring 43 rotates, it drives the convex ball rod 44 to rotate. When the convex ball rod 44 rotates, its own circular surface will conflict with the convex block 42 on the inner wall of the fixed plate 41. The circular surface of the convex ball rod 44 contacts the arc surface of the convex block 42 to generate a resistance force. At this time, the convex ball rod 44 pushes the sliding ring 43 to slide leftward inside the cylinder 14, and the sliding ring 43 drives the arc plate 45 to slide synchronously along the inside of the slide groove of the cylinder 14. When the convex ball rod 44 no longer conflicts with the convex block 42, the sliding ring 43 is reset by the elastic force of the spring inside the U-shaped rod 13, and the sliding ring 43 pulls the arc plate 45 to reset. This reciprocating motion enables the arc plate 45 to continuously perform horizontal rotation on the edge of the plywood. When the sliding ring 43 rotates, it drives the groove arc block 46 to rotate. When the groove arc block 46 rotates, its own groove constantly contacts the outer wall edge of the thin plate 47 and bends and deforms. When the groove arc block 46 no longer contacts the thin plate 47, the thin plate 47 will swing back and forth when it is reset by its own toughness, causing the cylinder 14 and the curved plate 45 to shake slightly. When the curved plate 45 is pressed against the plywood through the above cooperation, the shaking force carried by the curved plate 45 eliminates the bubbles or gaps between the two plates, so that the degree of fit between the plywood is further improved.

[0037] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes an anti-pollution device 5;

[0038] The anti-pollution device 5 includes an activated carbon plate 51 and a twisting plate 52. The inner wall of the top of the activated carbon plate 51 is hinged to the vertical surfaces of the outer walls on the left and right sides of the pressing plate 11, and a circular groove is provided on the inclined surface of the activated carbon plate 51 close to the center of the device body 1. The twisting plate 52 is fixedly installed between the inclined surface of the activated carbon plate 51 and the bottom edge of the pressing plate 11. The deviation amplitude of the activated carbon plate 51 is limited by the twisting plate 52. Through the above cooperation, the activated carbon plate 51 can slide back and forth up and down, which accelerates the absorption and purification of harmful gases generated when the glue of the plywood bonding part evaporates, thereby avoiding the long-term processing and absorption of harmful gases such as formaldehyde by the staff to endanger their health.

[0039] The anti-pollution device 5 also includes a fixed column 53, a cam 54 and a plurality of arc blocks 55. The bottom of the fixed column 53 is fixedly installed at the top center of the device body 1. The outer wall of the cam 54 is rotatably installed at the concave surface of the top of the fixed column 53, and the outer wall of the cam 54 is in contact with the circular groove of the activated carbon plate 51. The plurality of arc blocks 55 are equidistantly installed on the vertical surface of the outer wall of the cam 54 near the center of the device body 1 through spring sliding. Through the above coordination and the up and down movement of the activated carbon plate 51, the arc blocks 55 are caused to rotate to disturb the formaldehyde gas contacting the activated carbon plate 51, so that the formaldehyde gas can evenly and quickly enter the activated carbon plate 51 for purification, thereby preventing the accumulation of harmful gases from polluting the environment.

[0040] The anti-pollution device 5 also includes a plurality of arc blocks 56, a rotating rod 57 and a resistance ring 58. The plurality of arc blocks 56 are equidistant from the center side of the cam 54 and are fixedly installed on the arc block 55 near the center side of the cam 54. The rotating rod 57 is fixedly installed on the vertical surface of the outer wall of the cam 54 near the center side of the activated carbon plate 51, and a spiral groove is provided on the outer wall of the rotating rod 57. The resistance ring 58 penetrates through the inside and is slidably installed on the outer wall surface of the rotating rod 57. The arc surface of the arc block 56 is located on the arc surface motion trajectory of the resistance ring 58. Through the above cooperation, the arc block 55 is continuously resisted against the inclined surface of the activated carbon plate 51, causing the activated carbon plate 51 to swing back and forth during the downward movement, further improving the absorption speed and purification efficiency of the formaldehyde gas, so that the activated carbon plate 51 itself can fully participate in the purification process, avoiding uneven absorption and shortening the replacement cycle of the activated carbon plate 51.

[0041] When in use, the pressing plate 11 moves downward and drives the activated carbon plate 51 to move synchronously. The inner wall inclined surface of the activated carbon plate 51 slides downward along the arc surface at the top of the blower 3. The activated carbon plate 51 causes its own hinge shaft to rotate through the resistance force between the activated carbon plate 51 and the arc surface at the top of the blower 3. At the same time, the activated carbon plate 51 pulls the torsion plate 52 to deform synchronously. When the activated carbon plate 51 is reset, it drives the torsion plate 52 to reset. The deviation amplitude of the activated carbon plate 51 is limited by the torsion plate 52. The above cooperation enables the activated carbon plate 51 to slide up and down reciprocatingly, which speeds up the glue bonding of the plywood. The harmful gases generated during volatilization are absorbed and purified to avoid the workers from absorbing harmful gases such as formaldehyde during long-term processing and endangering their health; at the same time, when the circular groove of the activated carbon plate 51 contacts the outer wall of the cam 54, the friction force causes the cam 54 to generate a rotational force and start to rotate. At this time, the top of the fixed column 53 of the cam 54 rotates, and at the same time, when the activated carbon plate 51 moves downward, the cam 54 is caused to rotate counterclockwise, and when the activated carbon plate 51 moves upward, the cam 54 is caused to rotate clockwise. Subsequently, the cam 54 drives the arc block 55 to rotate. Through the above cooperation and the up and down movement of the activated carbon plate 51, When the arc block 55 rotates, it disturbs the formaldehyde gas contacting the activated carbon plate 51, so that the formaldehyde gas can evenly and quickly enter the activated carbon plate 51 for purification, thereby preventing the accumulation of harmful gases from polluting the environment; when the cam 54 rotates, it drives the rotating rod 57 to rotate, and when the rotating rod 57 rotates, the non-self-locking spiral groove on its outer wall restricts the abutment ring 58, and the internal block of the abutment ring 58 contacts the inner wall of the spiral groove, so that the abutment ring 58 can slide left and right along the outer wall of the rotating rod 57 when the rotating rod 57 rotates counterclockwise and clockwise, When the contact ring 58 slides, its own arc surface will resist the arc surface of the arc block 56 moving away from the center of the cam 54, and the arc block 56 will push the arc block 55 to move synchronously. Then the arc block 56 is reset by the spring force, and this process repeats. Through the above cooperation, the arc block 55 is prompted to continuously resist the inclined surface of the activated carbon plate 51, causing the activated carbon plate 51 to swing back and forth during the downward movement, further improving the absorption speed and purification efficiency of the formaldehyde gas, so that the activated carbon plate 51 itself can fully participate in the purification process, avoiding uneven absorption and shortening the replacement cycle of the activated carbon plate 51.
