Description

Technical Field

[0001] The utility model belongs to the technical field of paper tray transfer equipment, and in particular relates to a mechanism component for automatically transferring paper trays. Background Art

[0002] Paper pallets are made of waste newspapers and carton paper as the main raw materials. They are pulped with additives in a certain ratio, dehydrated and formed through special molds, and then dried, heat treated, and shaped. Pulp molded products are recyclable and degradable. After adding special processes, they have good waterproof and oil-proof properties. They can completely replace plastic foam products, effectively eliminate "white pollution", and are environmentally friendly. After the production of paper pallets is completed, the paper pallets need to be stacked and transferred from the production line to the warehouse. When stacking the cardboard, mechanical auxiliary alignment is required to ensure that the paper pallets are stacked neatly. During the auxiliary alignment process, if the mechanical force is too large, it is easy to squeeze and collide the cardboard, causing the cardboard to deform. In addition, the paper pallets need to be aligned during the stacking process. If they are not aligned, the center of gravity will easily deviate and tip over during the transportation process, and the transportation efficiency of the cartons is low. Utility Model Content

[0045] The first adjustment plate 51 is arranged at the front and rear sides of the unloading port 3, and a moving rod 53 is fixedly connected to the opposite side of the first adjustment plate 51, and a threaded hole is provided at the other end of the moving rod 53. A threaded rod 7 is rotatably provided at the bottom of the transfer platform 1, and the threads at both ends of the threaded rod 7 are in opposite directions. The moving rod 53 is threadedly connected to the threaded rod 7 through the threaded hole. A motor 71 is provided at the bottom of the transfer platform 1, and the output end of the motor 71 is connected to the threaded rod 7.

After adjusting the distance between the first adjustment plates 51, adjust the distance between the second adjustment plates 52 through the relative moving mechanism 8. After the distances of the front, back, left and right of the discharge port 3 are adjusted to adapt to the corresponding paper tray size, the formed paper tray is transferred from the paper tray output conveyor belt 2 to the transfer platform 1, and the edge of the paper tray is clamped by the clamping mechanism 6. Driven by the rotating belts 41 at both ends of the transfer platform 1, the paper tray moves to the center of the discharge port 1 and falls along the center of the discharge port 1. Under the corrective action of the first adjustment plate 51 and the second adjustment plate 52, the paper tray will not be displaced or offset during the falling process, which can ensure that the paper tray is finally stacked flat and has a consistent center of gravity.

[0049] Preferably, the relative movement mechanism 8 includes a first rack 81 and a second rack 82, wherein the first rack 81 is slidably disposed on the lower end surface of the first slide groove 54, and the second rack 82 is slidably disposed on the upper end surface of the first slide groove 54, and a gear 83 is rotatably disposed in the middle of the first slide groove 54, and the gear 83 is meshed and connected with the first rack 81 and the second rack 82;

An electric telescopic rod 84 is fixedly provided at the bottom of the transfer table 1. The output end of the electric telescopic rod 84 is fixedly connected to one of the second adjustment plates 52. The second adjustment plate 52 connected thereto is pushed to move left or right by the electric telescopic rod 84, and the first rack 81 or the second rack 82 connected to the second adjustment plate 52 moves and drives the gear 83 meshing therewith to rotate. The rotation of the gear 83 drives the second rack 82 or the first rack 81 meshing therewith at the other end to move, thereby driving the other second adjustment plate 52 connected thereto to move relative to or away from the second adjustment plate 52, so as to adjust the left and right lengths of the paper tray 3 after unloading to adapt to the falling of paper trays of different sizes.

[0051] Preferably, a second slide groove 55 is provided in the first slide groove 54 , the second slide groove 55 is T-shaped, a second slider 85 is slidably connected in the second slide groove 55 , and the second slider 85 is fixedly connected to the first rack 81 or the second rack 82 .

[0052] Preferably, a sliding rod 72 is fixedly provided at the bottom of the transfer platform 1, and a pair of moving rods 53 are provided on the first adjustment plate 51 and are respectively arranged at both ends of the first adjustment plate 51, one of the moving rods 53 is connected to the threaded rod 7, and the other moving rod 53 is slidably connected to the sliding rod 72. By setting a pair of moving rod 53 shells, the stability of the first adjustment plate 51 during the movement process is improved.

[0053] Preferably, the clamping mechanism 6 includes a first clamping plate 61, one end of which is fixedly arranged on the side of the rotating belt 41, a spring 64 is fixedly arranged at the lower end of the first clamping plate 61, the other end of the spring 64 is fixedly connected to a second clamping plate 62, and a third clamping plate 63 is arranged on the second clamping plate 62, and the third clamping plate 63 is used to clamp the paper holder;

[0054] The transfer platform 1 is provided with a baffle plate 65 , and the baffle plate 65 is arranged at both sides of the front and rear of the material discharge port 3 .

[0055] Preferably, the side of the retaining plate 65 away from the feeding port 3 is arc-shaped, and the left and right side surfaces of the second clamping plate 62 are arc-shaped. When the second clamping plate 62 is squeezed by the retaining plate, the arc shape can reduce resistance.

[0056] Preferably, a protective plate 66 is rotatably provided on the top of the second clamping plate 62, and a third slide groove 67 is opened on the first clamping plate 61. The other end of the protective plate 66 is slidably arranged in the third slide groove 67. When the second clamping plate 62 is squeezed by the abutment plate 65, the protective plate 66 moves up along the third slide groove 67. When the second clamping plate 62 leaves the abutment plate 65, the protective plate 66 moves down along the third slide groove 67 due to the elastic rebound of the spring 64. Due to the limiting type of the third slide groove 67, the spring 64 can be prevented from rebounding repeatedly due to excessive elastic force, thereby protecting the second clamping plate 62.

[0057] Preferably, a fourth slide groove 68 is provided on the side of the second clamping plate 62 away from the first clamping plate 61, and a connecting block 69 is provided on the third clamping plate 63.

The second clamping plate 63 can be replaced to adapt to the clamping of paper holders of different shapes.

[0058] The working principle of the utility model is as follows: first, according to the length and width of the paper tray to be stacked, the motor 71 is started to rotate and drive the threaded rod 7 to rotate, and the moving rods 53 at both ends of the threaded rod 7 move relative to or away from each other along the axial direction of the threaded rod 7, thereby driving the first adjustment plate 51 to move relative to or away from each other, and after adjusting the distance between the first adjustment plates 51, the second adjustment plate 52 connected thereto is pushed to move left or right by the electric telescopic rod 84, and the first rack 81 or the second rack 82 connected to the second adjustment plate 52 moves and drives the gear 83 meshing therewith to rotate, and the rotation of the gear 83 drives the second rack 82 or the first rack 81 meshing therewith at the other end to move, thereby driving the other second adjustment plate 52 connected thereto to move relative to or away from the second adjustment plate 52, and adjusting the unloading channel corresponding to the unloading port 3 to the corresponding paper tray. After the length and width are measured, the paper tray is formed and then transported to the transfer platform 1 on the output conveyor belt 2. The third clamping plate 63 of the clamping mechanism 6 located at the front and rear ends of the transfer platform 1 clamps the paper tray front and back. During the rotation of the rotating belt 41, the clamping mechanism 6 drives the paper tray to move toward the lower feed port 3. When passing through the blocking plate 65, the second clamping plate 62 and the spring 64 are squeezed toward the first clamping plate 61 due to the resistance of the blocking plate 65, thereby driving the third clamping plate 63 to move. When passing through the center position of the feed port 3, the third clamping plate 63 is released from the clamping effect on the paper tray, and the paper tray falls along the feed channel composed of the first adjusting plate 51 and the second adjusting plate 52. Under the corrective action of the first adjusting plate 51 and the second adjusting plate 52, the paper tray will not be displaced or offset during the falling process. This is repeated to ensure that the paper tray is finally stacked flat and has a consistent center of gravity.

[0059] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
