Description

Technical Field

[0001] The utility model relates to the technical field of polyethylene processing, in particular to a blanking guiding device for polyethylene plate production. Background Technique

[0002] The polyethylene plate is a long strip-shaped thin plate formed after the raw materials are extruded by an extruder. The texture of the long strip-shaped thin plate is relatively soft. When discharging from the extruder, the end of the long strip-shaped thin plate will droop due to its own weight. Therefore, it is necessary for the operator to manually catch the end of the thin plate and pull it outwards, so that the thin plate remains in a long strip shape and does not fall to the ground, thus affecting the shape of the thin plate. In addition, it is also necessary for the operator to place the dividing plate for separating the thin plates between the thin plates, which can facilitate the subsequent material taking work of the coiler. Therefore, when the polyethylene thin plate is discharged, in order to ensure the successful discharge of the thin plate and separate the thin plates, it requires manual labor and reduces work efficiency. Content of the Utility Model

[0003] The purpose of this application is to provide a blanking guiding device for polyethylene plate production to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the following technical solutions are provided in this application:

[0005] A blanking guiding device for polyethylene plate production includes a machine body and a guiding component installed on one side of the machine body. The guiding component includes two connecting rods one, two connecting rods two, two connecting rods three, two cylinders one and a guiding rod. The two cylinders one are installed in front of the discharge port of the machine body and are symmetrically arranged. The output ends of the two cylinders one are movably connected to the bottom ends of the two connecting rods one. The ends of the two connecting rods one are respectively connected to one ends of the two connecting rods two by bearings.

The directional terms mentioned in the present utility model, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only with reference to the directions in the attached drawings. Therefore, the directional terms used are for explaining and understanding the present utility model, rather than for limiting the present utility model.

[0016] As Figures 1-5 shown, a blanking guiding device for polyethylene sheet production includes a machine body 1 and a guiding component installed on one side of the machine body 1. The guiding component includes two first connecting rods 4, two second connecting rods 5, two third connecting rods 6, two first cylinders 10 and a guiding rod 8. Two side plates 2 are fixedly installed on both sides of the machine body 1. Rotating rods 12 are fitted and installed on the inner walls of the two side plates 2. The bottom of the rotating rod 12 is connected to the inner wall of the side plate 2 by a bearing, and a material receiving rod 13 is fixedly installed at the top of the rotating rod 12. A second cylinder 14 is fitted and arranged on the inner wall of the side plate 2. The output end of the second cylinder 14 is connected to the outer wall of the rotating rod 12 by a bearing, and the end of the second cylinder 14 away from the output end is connected to the inner wall of the side plate 2 by a bearing. The material receiving rod 13 is arranged between the guiding rod 8 and the discharge port of the machine body 1.

[0017] A placing table 3 is installed on one side of the discharge port of the machine body 1. A limiting rod 9 is fixedly installed on the tabletop of the placing table 3. The two first cylinders 10 are both fixedly installed on the placing table 3. The two first cylinders 10 are symmetrically arranged. The output end of the first cylinder 10 faces away from the machine body 1 on the side of the placing table 3. A pushing block 15 is fixedly installed at the output end of the first cylinder 10. A fixing rod 11 is fixedly installed on the outer wall of the output end of the first cylinder 10. The end of the fixing rod 11 is connected to the bottom end of the first connecting rod 4 by a bearing. A number of dividing plates are stacked and placed above the placing table 3. The function of the dividing plate is to separate multiple polyethylene thin plates, which is convenient for subsequent winding and taking of the thin plates. A notch is opened on one side of the dividing plate. The shape of one end of the notch is adapted to the outer wall shape of the limiting rod 9. In this way, the dividing plate can be sleeved on the outside of the limiting rod 9 through the notch, and the dividing plate is pushed so that one end of the notch abuts against the outer wall of the limiting rod 9, which is convenient for aligning multiple dividing plates. In the initial state, the output end of the first cylinder 10 is in a contracted state, and the outer wall of the pushing block 15 abuts against the edge outer wall of the lowermost dividing plate. The thickness of the pushing block 15 is less than the thickness of the dividing plate.

[0018] The top ends of the two first connecting rods 4 are both connected to one end of the two second connecting rods 5 by bearings. The other ends of the two second connecting rods 5 are both connected to the outer wall of the guiding rod 8 by bearings. Both ends of the guiding rod 8 are connected to one end of the third connecting rod 6 by bearings. Connecting rods 7 are fixedly installed on the inner walls of the two side plates 2. The end of the connecting rod 7 is connected to the end of the third connecting rod 6 away from the guiding rod 8 by a bearing. In the initial state, the first connecting rod 4 and the second connecting rod 5 are in a folded state, and the height of the guiding rod 8 is lower than the top of the side plate 2.

[0019] The machine body 1 extrudes the formed polyethylene thin plate from the discharge port. The polyethylene thin plate extruded from the discharge port will pass above the material receiving rod 13. After the end of the polyethylene thin plate passes the material receiving rod 13, the second cylinder 14 starts. The output end of the second cylinder 14 pushes the rotating rod 12. The rotating rod 12 rotates with the bottom end as the axis. The second cylinder 14 adjusts its own position according to the rotation amplitude of the rotating rod 12. The rotating rod 12 drives the material receiving rod 13 at the top to rotate, and the material receiving rod 13 drives the end of the polyethylene thin plate to move towards the direction of the guide rod 8. Since the polyethylene thin plate has a soft material, the end of the long strip-shaped thin plate is likely to droop downward due to its own weight. After drooping, the end will be lower than the top of the side plate 2. Therefore, in the initial state, the first connecting rod 4 and the second connecting rod 5 are in a folded state, and the height of the guide rod 8 is lower than the top of the side plate 2. After the end of the thin plate passes above the guide rod 8, the first cylinder 10 starts. The output end of the first cylinder 10 drives the pushing block 15 to push the bottommost material dividing plate on the placing table 3, so that the material dividing plate is quickly pushed out of the placing table 3 and will slide forward for a certain distance due to inertia. At this time, the output end of the first cylinder 10 drives the bottom end of the first connecting rod 4 to slide forward through the fixing rod 11 at the same time. The first connecting rod 4 drives the second connecting rod 5, the second connecting rod 5 drives the guide rod 8, and the guide rod 8 drives the third connecting rod 6. After the output end of the first cylinder 10 extends to the maximum value, the first connecting rod 4 and the second connecting rod 5 become a straight line state, the position of the guide rod 8 rises, and the third connecting rod 6 rotates with the connecting rod 7 as the axis to provide guidance for the position change of the guide rod 8. At this time, the guide rod 8 rises, lifts the drooping end of the polyethylene thin plate upward, so that the polyethylene thin plate can continue to extend forward and fall on the material dividing plate. After the polyethylene thin plate extends out of the machine body 1 for a certain distance, it will be cut. After cutting is completed, the first cylinder 10 and the second cylinder 14 reset and wait to work again after the next polyethylene thin plate is extruded by the machine body 1.

[0020] The above embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
