[0059] 3. The present invention utilizes the characteristics that unmounted paper is easy to deform and that paper bonded to a wooden board is not easy to deform, and arranges corresponding force-bearing rods on the guide slide, so that the force-bearing rods change accordingly according to different papers, which helps to enhance the pertinence of the screening mechanism when clamping the paper. When the force-bearing rods shrink, the support plate will extend inward to increase the contact surface with the paper, which helps to improve the stability of the screening mechanism when clamping the paper.

[0060] 4. The present invention determines the front and back sides of the paper through a photoelectric detector, thereby controlling the fifth motor to perform different degrees of rotation. When the paper is placed with the front side facing up, the fifth motor drives the shaft to rotate 180°, so that the paper enters the second conveying path. When the paper is placed with the back side facing up, the fifth motor drives the shaft to rotate 90°, so that the paper enters the first conveying path, thereby completing the front and back side sorting operation of the paper.

[0088] Reference Manual Attached Figure 5 The position adjustment unit 11 is arranged on the placement table 8. The position adjustment unit 11 is used to adjust the position of the paper, and the position adjustment unit 11 is composed of a photoelectric sensor 1101 and a bidirectional roller 1102. The bidirectional roller 1102 is arranged on both sides of the photoelectric sensor 1101. The photoelectric sensor 1101 senses the position of the paper on the placement table 8, and controls the bidirectional roller 1102 to make corresponding adjustments to the position of the paper, so that the paper is arranged concentrically with the placement table 8. It should be noted that the control system between the photoelectric sensor 1101 and the bidirectional roller 1102 is a well-known technology in the prior art field, so it will not be described in detail.

[0089] Reference Manual Attached Figure 6Based on the setting of the placement table 8, in order to adjust the inclination angle of the placement table 8 according to the paper sorting requirements, an adjustment component is provided on the placement table 8, and the adjustment component is used to adjust the center of gravity position of the placement table 8. The inclination angle adjustment operation of the placement table 8 is achieved by changing the center of gravity position of the placement table 8.

[0090] The adjustment assembly includes a second motor 12, a receiving slot 13, a second lead screw 14, a second movable slider 15 and a counterweight 16, and the components are arranged as follows:

[0091] The second motor 12 is fixedly installed on the placement table 8, the storage slot 13 is opened on the placement table 8, the second lead screw 14 is rotatably installed in the storage slot 13 and fixedly connected to the output end of the second motor 12, and the second movable slider 15 is matched with the second lead screw 14. The counterweight block 16 is fixedly connected to the second movable slider 15. It should be noted that: the counterweight block 16 is a rectangular structure. Based on the setting of the placement table 8, in order to reduce the load of the second lead screw 14 and the second movable slider 15, two guide slots for sliding the counterweight block 16 are opened on the placement table 8, and the two guide slots are symmetrically opened on both sides of the storage slot 13. The counterweight block 16 is connected to the guide slot through a dovetail slider, and the sliding connection between the two guide slots and the counterweight block 16 is realized to realize multi-point connection of the counterweight block 16, thereby reducing the load of the second lead screw 14 and the second movable slider 15 during operation, which helps to extend the service life of the second lead screw 14 and the second movable slider 15;

[0092] Based on the setting of the sorting bracket 4, in order to sort the paper that has been processed by paper mounting or not, a screening mechanism is provided on the sorting bracket 4, and the screening mechanism sorts the paper that has been processed by paper mounting or not through high-pressure airflow;

[0093] The screening mechanism includes a third motor 17, a third lead screw 18, a third movable slider 19, a first cylinder 20, a mounting frame 21, a fourth motor 22, a driving disk 23, a fixing disk 24, a guide slide 25, a first traction rod 26, an air jet part 27 and a clamping assembly, and the components are arranged as follows:

[0094] The third motor 17 is fixedly mounted on the sorting bracket 4, the third lead screw 18 is rotatably mounted on the sorting bracket 4 and fixedly connected to the output end of the third motor 17, and the third movable slider 19 is matched with the third lead screw 18. It should be noted that the first movable slider 7, the second movable slider 15 and the third movable slider 19 are respectively embedded with lead screw nuts matched with the first lead screw 6, the second lead screw 14 and the third lead screw 18.

[0095] The first cylinder 20 is fixedly mounted on the third movable slider 19, the mounting frame 21 is fixedly connected to the output end of the first cylinder 20, a guiding straight slot is provided on the sorting bracket 4, and the mounting frame 21 is fixedly connected with a guide rod extending into the guiding straight slot, and the guide rod is guided and limited by the guiding straight slot, thereby providing a guiding support function when the mounting frame 21 moves horizontally.

[0096] The fourth motor 22 is fixedly mounted on the mounting frame 21, the driving disk 23 is fixedly connected to the output end of the fourth motor 22, the fixed disk 24 is fixedly connected to the mounting frame 21, the guide slide 25 is slidably mounted on the fixed disk 24, and both ends of the first traction rod 26 are pin-connected to the guide slide 25 and the driving disk 23 respectively. The first traction rod 26 drives the guide slide 25 to move radially through the position difference generated during the rotation of the driving disk 23, and four guide slides 25 and four first traction rods 26 are provided, which helps to ensure the synchronization of the guide slide 25 during movement.

[0097] The jet part 27 is concentrically arranged on the fixed plate 24, and the jet part 27 is composed of a high-pressure air pump 2701, a pressure regulating valve 2702, a gas hose 2703 and a high-pressure nozzle 2704. The high-pressure air pump 2701 and the high-pressure nozzle 2704 are fixedly installed on the fixed plate 24, and the pressure regulating valve 2702 is matched between the high-pressure air pump 2701 and the gas hose 2703. The gas hose 2703 is connected between the high-pressure air pump 2701 and the high-pressure nozzle 2704. It should be noted that the control system between the high-pressure air pump 2701, the pressure regulating valve 2702, the gas hose 2703 and the high-pressure nozzle 2704 is a well-known technology in the prior art, so it will not be described in detail.

[0098] Based on the setting of the guide slide 25, in order to further improve the clamping stability of the guide slide 25 on the paper, a clamping assembly is provided on the guide slide 25. The clamping assembly includes an upper baffle 28, a lower baffle 29, a fan-shaped plate 30, a rectangular plate 31, a force rod 32, a driving plate 33, a sliding groove 34, a sliding block 35, a return spring 36, a support plate 37, a first movable groove 39, a first movable block 40, a driving rod 38, a second movable groove 62, a second movable block 63, and a second traction rod 41. The components are arranged as follows:

[0099] The upper baffle 28 is fixedly connected to the guide slide 25, and the lower baffle 29 is fixedly connected to the guide slide 25. A serrated rubber pad is arranged between the upper baffle 28 and the lower baffle 29. Due to the characteristic that the serrated rubber pad is easily deformed when subjected to force, when the paper processed after paper mounting is located between the upper baffle 28 and the lower baffle 29, the serrated rubber pad will be deformed under force. When the paper processed after paper mounting does not move between the upper baffle 28 and the lower baffle 29, since the serrated rubber pad has an elastic reset function, the paper processed after paper mounting is located between the upper baffle 28 and the lower baffle 29 and will continue to be subjected to the upper and lower squeezing forces generated by the two serrated rubber pads, thereby further improving the stability of the paper processed after paper mounting when it is clamped and limited.

[0100] The fan-shaped plate 30 is fixedly connected to the lower baffle 29, and the rectangular plate 31 is fixedly connected to the end of the fan-shaped plate 30 away from the lower baffle 29. It should be noted that the initial position of the rectangular plate 31 is arranged corresponding to the upper and lower positions of the placement groove 10. The paper that has not been processed by paper mounting will be deformed toward the center of the paper when it contacts the fan-shaped plate 30 due to its soft texture. Then, when the air jet part 27 is started, the paper that has not been processed by paper mounting will directly fall onto the lifting platform 3, and the paper that has not been processed by paper mounting will be transported to the transport roller 2 by adjusting the inclination angle of the placement table 8. At the outlet end, the paper processed by paper mounting is pasted on the wooden board, so the texture of the paper processed by paper mounting is hard and not easy to deform. The paper processed by paper mounting is squeezed by the fan-shaped plate 30 and moves upward along the arc structure on the upper surface of the fan-shaped plate 30, so that the paper processed by paper mounting enters between the upper baffle plate 28 and the lower baffle plate 29, so as to stably clamp the paper processed by paper mounting, so that when the jet part 27 is started, the paper processed by paper mounting will not move due to the influence of the high-pressure airflow, thereby screening whether the paper has been processed by paper mounting.

[0101] The force-bearing rod 32 is slidably mounted on the lower baffle 29, and the driving plate 33 is fixedly connected to the force-bearing rod 32. It should be noted that: since the texture of paper that has not been mounted is softer, and the texture of paper that has been mounted is harder, only when the paper that has been mounted contacts the force-bearing rod 32 can the force-bearing rod 32 be pushed to move horizontally.

[0102] The sliding groove 34 is opened on the guide slide 25, the sliding block 35 is slidably mounted in the sliding groove 34, and the reset spring 36 is fixedly connected between the sliding block 35 and the sliding groove 34. Through the setting of the reset spring 36, the sliding block 35 is reset when not pulled. The support plate 37 is fixedly connected to the sliding block 35, and the guide plate 9 is provided with a first movable opening for movably mounting the guide slide 25 and the support plate 37, so as to avoid motion interference between the guide slide 25 and the support plate 37 when performing radial motion.

[0103] The first movable groove 39 is provided on the support plate 37, the first movable block 40 is slidably mounted in the first movable groove 39, the middle end pin of the driving rod 38 is installed on the guide slide plate 25, and the lower end pin of the driving rod 38 is installed on the first movable block 40. The position difference generated by the rotation of the driving rod 38 drives the support plate 37 to extend horizontally, thereby increasing the contact point with the paper that has been mounted, and further improving the stability when clamping the paper that has been mounted. The second movable groove 62 is provided on the driving rod 38, and the second movable block 63 is slidably mounted in the second movable groove 62. The two ends of the second traction rod 41 are respectively pin-connected to the driving plate 33 and the second movable block 63. The first movable groove 39 and the first movable block 40 and the second movable groove 62 and the second movable block 63 provide a movable space for the rotational movement of the driving rod 38, thereby avoiding the second traction rod 41 and the support plate 37 from causing movement interference to the driving rod 38.

[0104] The sorting bracket 4 is provided with a conveying mechanism, which is used to convey the paper that is located in the screening mechanism and has been processed by paper mounting to the detection mechanism that is located in a different plane from the screening mechanism.

[0105] The conveying mechanism includes a first guide frame 42, a second guide frame 43, a driving block 44, a bearing plate 45, a third traction rod 46, a second cylinder 61 and an L-shaped plate 47, and each component is arranged as follows:

[0106] The first guide frame 42 and the second guide frame 43 are respectively arranged on the sorting bracket 4, and the first guide frame 42 is located below the second guide frame 43. The driving block 44 is slidably mounted in the first guide frame 42, and the driving block 44 is guided and limited by the first guide frame 42, so that the driving block 44 can only perform linear motion in the horizontal direction. The carrying plate 45 is slidably mounted in the second guide frame 43, and the carrying plate 45 is guided and limited by the second guide frame 43, so that the carrying plate 45 can only perform linear motion in the horizontal direction, and the bottom end of the carrying plate 45 slides against the bottom end of the first guide frame 42, so that the bottom end of the carrying plate 45 is always restricted by the first guide frame 42 when it does not contact the L-shaped plate 47, and the carrying plate 45 cannot deviate downward The second cylinder 61 is fixedly connected to the first guide frame 42, and the output end of the second cylinder 61 is fixedly connected to the driving block 44, and the two ends of the third traction rod 46 are respectively pin-connected to the driving block 44 and the supporting plate 45. The second cylinder 61 drives the driving block 44 to perform horizontal movement. When the driving block 44 moves, it will pull the lower end of the third traction rod 46 to perform linear movement, so that the other end of the third traction rod 46 drives the supporting plate 45 to perform horizontal movement. When the supporting plate 45 contacts the L-shaped plate 47, the supporting plate 45 is not restricted by the second guide frame 43. However, due to the active conflict between the L-shaped plate 47 and the supporting plate 45, when the driving block 44 continues to perform horizontal movement, the supporting plate 45 moves upward under the traction of the third traction rod 46.

[0107] The bearing plate 45 is provided with a baffle 4501, a movable pulley 4502, a slot 4503 and a lower wedge block 4504, and the components are arranged as follows:

[0108] The baffle 4501 is fixedly connected to three sides of the supporting plate 45, and the movable pulley 4502 is arranged on the supporting plate 45. The movable pulley 4502 can reduce the friction resistance generated with the L-shaped plate 47. The slot 4503 is opened on the movable pulley 4502, and the lower wedge block 4504 is fixedly connected to the movable pulley 4502.

[0114] The clamping plate 53 is slidably mounted on the first mounting plate 51, the third cylinder 54 is fixedly mounted on the second mounting plate 52, and both ends of the fourth traction rod 55 are pin-connected to the output end of the third cylinder 54 and the clamping plate 53 respectively. The position difference generated when the fourth traction rod 55 is deflected drives the clamping plate 53 to move toward each other, so as to limit the paper after paper mounting, thereby preventing the paper after paper mounting from being deflected by the centrifugal force generated by the rotation of the rotating shaft 50.

[0115] The photoelectric detector 56 is fixedly connected to the production line body 1. The photoelectric detector 56 is used to judge the front and back sides of the paper after paper mounting. The photoelectric detector 56 is connected to the fifth motor 49 by electrical signals.

[0118] It should be noted that the specific models and specifications of the motor, position adjustment unit 11, cylinder, jet unit 27, photoelectric detector 56 and conveyor path need to be selected and determined according to the actual specifications of the production line body 1. The specific selection calculation method adopts the existing technology in this field, so it will not be repeated.

[0119] The present invention can be explained by the following operation mode:

[0125] The fourth motor 22 drives the driving disk 23 to rotate, and the driving disk 23 drives one end of the first traction rod 26 to perform linear motion. The other end of the first traction rod 26 pulls the guide slide 25 to perform radial motion on the fixed disk 24. The guide slide 25 drives the upper baffle 28 and the lower baffle 29 to perform radial motion. The lower baffle 29 drives the rectangular plate 31 to perform radial motion through the fan-shaped plate 30.

[0126] When the paper is not laminated:

[0127] The paper moves from the rectangular plate 31 to the fan-shaped plate 30. Since the upper surface of the fan-shaped plate 30 is an arc-shaped structure and the paper is not processed, the texture of the paper is relatively soft and easily deformed. Therefore, the paper will deform toward the center position under the action of gravity, and the paper will not squeeze the force-bearing rod 32 set between the upper baffle 28 and the lower baffle 29. At this time, the air jet part 27 ejects airflow to impact the paper, so that the paper is forced to break away from the rectangular plate 31, so that the paper falls onto the placement table 8, and the position adjustment part 11 is activated to guide the position of the paper, so that the paper moves onto the placement table 8;

[0128] The first motor 5 drives the first lead screw 6 to rotate, the first lead screw 6 drives the first movable slider 7 to move vertically downward, the first movable slider 7 drives the placement table 8 to move vertically downward, when the bottom end of the placement table 8 is horizontally aligned with the top end of the transport roller 2, the second motor 12 drives the second lead screw 14 to rotate, the second lead screw 14 drives the second movable slider 15 to move horizontally toward the end of the production line body 1 away from the input end, the second movable slider 15 drives the counterweight block 16 to move horizontally, so as to adjust the center of gravity position of the placement table 8, so that the placement table 8 rotates and tilts toward the end of the production line body 1 away from the input end under the action of gravity, and the paper slides down to the transport roller 2 set at the end of the production line body 1 away from the input end under the action of gravity;

[0129] When the paper is laminated:

[0130] The paper moves from the rectangular plate 31 to the fan-shaped plate 30. Since the upper surface of the fan-shaped plate 30 is an arc-shaped structure, the paper is forced to move upward, and the paper enters between the upper baffle plate 28 and the lower baffle plate 29. The paper squeezes the serrated rubber pad to deform the structure, and the paper squeezes the force-bearing rod 32 to move outward. The force-bearing rod 32 drives the driving plate 33 to move outward. The driving plate 33 drives the second traction rod 41 to deflect downward. The upper end of the second traction rod 41 drives the second movable block 63 to move in the second movable groove 62. The second traction rod 41 deflects The position difference generated by the rotation drives the upper end of the driving rod 38 to rotate based on the middle end of the driving rod 38, and the lower end of the driving rod 38 drives the first movable block 40 to move vertically upward in the first movable groove 39. The position difference generated by the rotation of the driving rod 38 drives the support plate 37 to move horizontally, and the support plate 37 drives the sliding block 35 to move horizontally in the sliding groove 34, squeezing the return spring 36 to increase the supporting area with the paper through the support plate 37, and the air jet part 27 sprays air to impact the paper, and the paper is not affected by the air flow at this time;

[0132] The fourth motor 22 drives the driving disk 23 to rotate in the opposite direction, and the driving disk 23 drives one end of the first traction rod 26 to perform linear motion. The other end of the first traction rod 26 pulls the guide slide 25 to perform radial motion toward the outer ring of the fixed disk 24. The guide slide 25 drives the upper baffle 28 and the lower baffle 29 to release the fixed position of the paper, and the paper slides onto the carrying plate 45. The baffle 4501 limits the three sides of the paper.

At this time, the end of the paper close to the L-shaped plate 47 is forced to move toward the baffle 4501;

[0135] The second cylinder 61 continues to drive the driving block 44 to move horizontally. At this time, since the bearing plate 45 cannot continue to move horizontally, when the lower end of the third traction rod 46 moves linearly, the other end of the third traction rod 46 pushes the bearing plate 45 to move vertically upward, so as to compensate for the movement. The moving pulley 4502 rotates on the L-shaped plate 47, and the lower wedge block 4504 drives the upper wedge block 4703 to move vertically upward. The upper wedge block 4703 moves vertically upward in the installation slide groove 4702, stretching the support spring 4704.
