Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1: Combination Figure 1-Figure 8 As shown, the present invention provides a technical solution: a cardboard conveying and feeding device for corrugated box production, comprising a fixed frame 1 and a cardboard piece 3, wherein a placing frame 2 is fixedly installed on the top of the fixed frame 1, and the cardboard piece 3 is placed in the placing frame 2, and a control component 4 is arranged on the fixed frame 1, and the control component 4 is used to intermittently push the cardboard piece 3 to move to one side, and two support plates 5 are fixedly connected to one side of the fixed frame 1, and a cleaning component 6 is arranged above the support plate 5 for cleaning the surface of the cardboard piece 3;

[0032] The cleaning assembly 6 includes a support frame 61 fixedly mounted on the top of the support plate 5, a pump body 62 is arranged on the top of the support frame 61, a delivery pipe 63 is arranged on the output end of the pump body 62, a suction pipe 64 is also arranged on the output end of the pump body 62, a dust collecting frame 65 is arranged on the other end of the suction pipe 64, a rotating rod 66 is rotatably connected in the dust collecting frame 65, a cleaning roller 67 is arranged on the outer wall of the rotating rod 66 for cleaning the surface of the cardboard piece 3, the cleaning roller 67 cleans the surface of the cardboard piece 3 by the rotation of the rotating rod 66, and at the same time, the pump body 62 is turned on, and the cleaned impurities are absorbed by the suction pipe 64 and the dust collecting frame 65, and then discharged through the delivery pipe 63 for collection and treatment;

[0033] A positioning rod 68 is fixedly connected to the top of the support plate 5, and a servo motor 69 is fixedly installed on the inner end of the positioning rod 68. The output end of the servo motor 69 is connected to the rotating rod 66 through a synchronous belt wheel transmission member 610. Eccentric wheels 614 are fixedly connected to both sides of the rotating rod 66. By turning on the servo motor 69 and cooperating with the synchronous belt wheel transmission member 610 to drive the rotating rod 66 to rotate synchronously, the rotating rod 66 drives the cleaning roller 67 to rotate, so that the cleaning roller 67 cleans the surface of the cardboard piece 3;

[0034] An L-shaped rod 611 is slidably connected to the outer end of the positioning rod 68, and a rectangular block 612 is fixedly connected to the outer wall of the L-shaped rod 611. A second damping spring 615 sleeved on the L-shaped rod 611 is arranged between the rectangular block 612 and the positioning rod 68. A pulley 613 is arranged on the side of the rectangular block 612 close to the eccentric wheel 614. An auxiliary rod 616 is fixedly connected to one side of the positioning rod 68. A slide seat 617 fixedly installed on the rectangular block 612 is slidably connected to the rotating rod 66. When the rotating rod 66 rotates, it can drive the eccentric wheel 614 to rotate synchronously. Under the elastic force of the second damping spring 615, the rectangular block 612 is pushed to move downward, so that the rectangular block 612 drives the pulley 613 to fit with the inner wall of the eccentric wheel 614, so that the rotating eccentric wheel 614 drives the pulley 613, the rectangular block 612, and the slide seat 617 to move up and down, and the slide seat 617 is located on the auxiliary rod 616 and slides;

[0035] A fixing plate 618 is fixedly installed at the bottom of the two support plates 5, a T-shaped plate 619 is slidably connected to the fixing plate 618, a fourth damping spring 630 is arranged between the T-shaped plate 619 and the fixing plate 618, and a row of knocking rods 620 for knocking the bottom of the cardboard piece 3 are fixedly connected to the top of the T-shaped plate 619. Under the elastic force of the fourth damping spring 630, the T-shaped plate 619 and the knocking rod 620 are pushed upward, so that the knocking rod 620 knocks the bottom of the cardboard piece 3;

[0036] The upper end of the fixed plate 618 is fixedly connected to a limiting rod 621, and both sides of the bottom end of the fixed plate 618 are fixedly connected to first trapezoidal blocks 622. The limiting rod 621 is used to limit the T-shaped plate 619;

[0037] Slide blocks 623 slidably mounted on the fixed plate 618 are provided on both sides of the T-shaped plate 619, and the outer ends of the slide blocks 623 are fixedly connected to the L-shaped rod 611, and the inner ends of the slide blocks 623 are fixedly connected to the pressing rods 624, which can drive the slide blocks 623 to move up and down synchronously when the L-shaped rod 611 moves up and down;

[0038] A slide groove 625 is provided inside the T-shaped plate 619, and a cross bar 626 is fixedly connected inside the slide groove 625. A second trapezoidal block 627 which is adapted to the pressure bar 624 is slidably connected to the cross bar 626, and one side of the second trapezoidal block 627 is slidably installed in the slide groove 625. A third damping spring 628 which is sleeved on the cross bar 626 is provided at the inner end of the second trapezoidal block 627. A guide rod 629 which is adapted to the first trapezoidal block 622 is fixedly connected to the side wall of the second trapezoidal block 627. When the slider 623 moves downward, the pressure bar 624 is driven to move downward synchronously. When the pressure bar 624 moves downward and contacts the top of the second trapezoidal block 627, the T-shaped plate 619, the knocking rod 620 and the second trapezoidal block 627 can be driven to move downward synchronously. When the guide rod 629 and the first trapezoidal block 622 After the contact, under the blocking action of the first trapezoidal block 622, the guide rod 629 and the second trapezoidal block 627 can move toward the inside of the T-shaped plate 619, and compress the third damping spring 628, so that the second trapezoidal block 627 enters the slide groove 625. At this time, the pressure rod 624 no longer forms a barrier to the second trapezoidal block 627. At the same time, the L-shaped rod 611 drives the slider 623 and the pressure rod 624 to move upward. At this time, the T-shaped plate 619 can push the T-shaped plate 619 and the knocking rod 620 to move upward under the elastic force of the fourth damping spring 630, so that the knocking rod 620 moving upward can knock the bottom of the cardboard piece 3. The knocking treatment helps to remove dust, paper scraps and other impurities on the surface of the cardboard piece 3, improve the cleanliness of the cardboard piece 3, and thus ensure the quality of the finished carton.

[0039] A row of L-shaped frames 631 are arranged on the outside of the two support plates 5, and rollers 632 are arranged on the top and side walls of the L-shaped frames 631. The two rollers 632 are used to limit the discharged cardboard pieces 3, so as to avoid the cardboard pieces 3 from being offset when discharged, which affects the subsequent corrugated box production.

[0040] In the embodiment of the present invention, by starting the servo motor 69 and cooperating with the appropriate synchronous belt pulley transmission member 610, we can realize the synchronous rotation of the rotating rod 66. This rotation action drives the cleaning roller 67 to rotate, so that the cleaning roller 67 can effectively clean the surface of the cardboard piece 3. At the same time, the pump body 62 is activated, and the impurities generated during the cleaning process are effectively absorbed and processed through the cooperation of the suction pipe 64 and the dust collecting frame 65. The processed impurities are discharged through the conveying pipe 63 and further collected and processed;

[0041] During the rotation of the rotating rod 66, it can also synchronously drive the eccentric wheel 614 to rotate. Under the elastic force of the second damping spring 615, the eccentric wheel 614 pushes the rectangular block 612 to move downward. As the rectangular block 612 moves downward, the pulley 613 fits tightly with the inner wall of the eccentric wheel 614, so that the rotating eccentric wheel 614 can drive the pulley 613, the rectangular block 612 and the slide seat 617 to move up and down.

[0042] When the L-shaped rod 611 moves up and down, it can synchronously drive the slider 623 to move up and down. When the slider 623 moves downward, it will prompt the pressure rod 624 to move downward. When the pressure rod 624 moves downward and contacts the top of the second trapezoidal block 627, it will push the T-shaped plate 619, the knocking rod 620 and the second trapezoidal block 627 to move downward together. When the guide rod 629 contacts the first trapezoidal block 622, the blocking effect of the first trapezoidal block 622 causes the guide rod 629 and the second trapezoidal block 627 to move toward the inner side of the T-shaped plate 619 and compress the third damping spring 628. In this way, the second trapezoidal Block 627 can smoothly enter the slide groove 625. At this time, the pressure rod 624 no longer blocks the second trapezoidal block 627. At the same time, the L-shaped rod 611 will drive the slider 623 and the pressure rod 624 to move upward. Under the elastic force of the fourth damping spring 630, the T-shaped plate 619 and the knocking rod 620 will also move upward. This upward movement enables the knocking rod 620 to knock the bottom of the cardboard piece 3. The knocking treatment helps to remove dust, paper scraps and other impurities on the surface of the cardboard piece 3, thereby improving the cleanliness of the cardboard piece 3. In this way, we can ensure the quality of the finished carton.

[0043] Embodiment 2: Combination Figure 2 , Figure 3 , Figure 4As shown, on the basis of the first embodiment, the design of the control component 4 includes mounting plates 41 fixedly mounted on both sides of the bottom of the fixing frame 1, a conveying shaft 42 is rotatably arranged between the two mounting plates 41, and a conveying belt 43 is arranged on the outer wall of the two conveying shafts 42. In order to further enhance the conveying efficiency, a pushing plate 45 is also arranged on the outer wall of the conveying belt 43. In particular, a driving motor 44 is arranged on one side of one of the conveying shafts 42, and the driving motor 44 is responsible for providing power to the conveying shaft 42 to ensure that the conveying belt 43 can smoothly convey materials;

[0044] The design of the placement frame 2 is equally sophisticated, with material troughs 21 on both sides of its surface, which are specifically used for the discharge of the movable plate 46. The movable plate 46 is slidably connected in the material trough 21, and a rectangular groove 47 that matches the push plate 45 is provided at the bottom of the movable plate 46, so as to ensure that the movable plate 46 and the push plate 45 can fit closely together, thereby achieving accurate material pushing. In addition, fixed rods 22 are fixedly connected on both sides of the placement frame 2, and one end of the movable plate 46 is slidably mounted on the fixed rod 22. Such a design not only ensures the stable movement of the movable plate 46, but also a first damping spring 23 located on one side of the movable plate 46 is provided through the outer wall of the fixed rod 22, thereby providing the necessary damping effect for the entire system to prevent the movable plate 46 from generating excessive impact or vibration during movement, thereby ensuring the smooth operation of the entire conveying system.

[0045] In the embodiment of the present invention, by placing the cardboard pieces 3 in the placement frame 2 in sequence, when the cardboard needs to be loaded and conveyed, the driving motor 44 is turned on to drive the conveying shaft 42 to rotate synchronously, so that the conveying shaft 42 cooperates with the conveyor belt 43 to drive the pushing plate 45 to move, and when the pushing plate 45 moves into the rectangular groove 47, the pushing plate 45 pushes the movable plate 46 to move on the material trough 21 of the placement frame 2 and compresses the first damping spring 23, so that the movable plate 46 pushes the cardboard piece 3 to be discharged from the material trough 21 and move to the support plate 5, and the cardboard piece 3 located above the cardboard piece 3 falls onto the movable plate 46, and when the pushing plate 45 moves to the bottom position, the movable plate 46 is under the elastic force of the first damping spring 23, The movable plate 46 is pushed to move to the side away from the support plate 5 to reset. At the same time, the cardboard pieces 3 in the placement frame 2 move downward under the blocking effect of the placement frame 2, so that the lowermost cardboard pieces 3 are flush with the movable plate 46, thereby facilitating the next transportation of the cardboard pieces 3. In addition, the cleaning roller can remove impurities, dust and debris on the surface of the cardboard to ensure the cleanliness of the cardboard surface; the cleaned cardboard can be better bonded and formed in the subsequent corrugated cardboard box production process, thereby improving the overall quality and strength of the carton. This design not only improves production efficiency, but also ensures the production quality of the carton, making the carton more stable during transportation and storage, reducing the breakage rate caused by cardboard quality problems, thereby reducing production costs to a certain extent.

[0046] Working principle of cardboard conveying and feeding device for corrugated box production:

[0047] When the cardboard pieces 3 are placed in the placement frame 2 in sequence, when the cardboard needs to be loaded and transported, the driving motor 44 is turned on to drive the conveying shaft 42 to rotate synchronously, so that the conveying shaft 42 cooperates with the conveyor belt 43 to drive the pushing plate 45 to move. When the pushing plate 45 moves into the rectangular groove 47, the pushing plate 45 pushes the movable plate 46 to move on the material groove 21 of the placement frame 2 and compresses the first damping spring 23, so that the movable plate 46 pushes the cardboard piece 3 to be discharged from the material groove 21 and move onto the supporting plate 5, and the cardboard piece 3 located above the cardboard piece 3 falls onto the movable plate 46. When the pushing plate 45 moves to the bottom position, the movable plate 46 is pushed to move to the side away from the supporting plate 5 and reset under the elastic force of the first damping spring 23. At the same time, under the blocking effect of the placement frame 2, the cardboard pieces 3 in the placement frame 2 move downward, so that the lowest cardboard piece 3 is flush with the movable plate 46, so as to facilitate the next cardboard piece 3 transportation.

[0048] Step 2: Turn on the servo motor 69 and cooperate with the synchronous belt pulley transmission member 610 to drive the rotating rod 66 to rotate synchronously, so that the rotating rod 66 drives the cleaning roller 67 to rotate, so that the cleaning roller 67 cleans the surface of the cardboard piece 3, and at the same time, turn on the pump body 62, and use the suction pipe 64 and the dust collecting frame 65 to absorb the cleaned impurities, and then discharge them through the conveying pipe 63 for collection and treatment;

[0049] When the rotating rod 66 rotates, it can drive the eccentric wheel 614 to rotate synchronously, and under the elastic force of the second damping spring 615, the rectangular block 612 is pushed downward, so that the rectangular block 612 drives the pulley 613 to fit the inner wall of the eccentric wheel 614, so that the rotating eccentric wheel 614 drives the pulley 613, the rectangular block 612, and the slide seat 617 to move up and down;

[0050] Step 3: When the L-shaped rod 611 moves up and down, it can drive the slider 623 to move up and down synchronously. When the slider 623 moves downward, it drives the pressure rod 624 to move downward synchronously. When the pressure rod 624 moves downward and contacts the top of the second trapezoidal block 627, it can drive the T-shaped plate 619, the knocking rod 620, and the second trapezoidal block 627 to move downward synchronously. When the guide rod 629 contacts the first trapezoidal block 622, under the blocking effect of the first trapezoidal block 622, the guide rod 629 and the second trapezoidal block 627 can move to the inside of the T-shaped plate 619 and compress the third damping spring 628. , so that the second trapezoidal block 627 enters the slide groove 625, at this time, the pressure rod 624 no longer forms an obstacle to the second trapezoidal block 627, and at the same time, the L-shaped rod 611 drives the slider 623 and the pressure rod 624 to move upward. At this time, the T-shaped plate 619 can push the T-shaped plate 619 and the knocking rod 620 to move upward under the elastic force of the fourth damping spring 630, so that the knocking rod 620 moving upward knocks the bottom of the cardboard piece 3. The knocking treatment helps to remove impurities such as dust and paper scraps on the surface of the cardboard piece 3, improve the cleanliness of the cardboard piece 3, and thus ensure the quality of the finished carton.
