Technical Field

[0001] The utility model relates to the technical field of PE plastic preparation, in particular to a PE film plastic particle feeding device. Background Art

[0002] PE film is the simplest macromolecular organic compound and one of the most widely used polymer materials in the world today. When using plastic pellets to produce PE plastic, a hopper is connected to one end of the blow molding machine's feed port. To add material, the operator first moves a bag filled with plastic pellets over the feed hopper, then opens the bag and pours the pellets into the hopper. This traditional manual feeding method is extremely inefficient, time-consuming, and labor-intensive. Therefore, a PE film plastic pellet feeding device has been proposed. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a PE film plastic particle feeding device.

Rollers are provided at the lower ends of the vertical rods, and the rollers are respectively built into the guide grooves on the corresponding side and slide along them.

[0009] In a preferred technical solution, the guide groove consists of two horizontal straight grooves that are staggered in height and one inclined groove for connecting the two straight grooves.

[0010] A screw mechanism and a loading platform are provided on the support platform. A connecting arm is rotatably installed on the screw mechanism. The movable end of the connecting arm is hinged to the bottom surface of the loading platform.

DETAILED DESCRIPTION

[0020] 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.

[0021] In this embodiment, refer to Figure 1-3 A PE film plastic particle feeding device includes a feed box 1 and a hopper 19. The hopper 19 is located at one end of the feed box 1. A conveyor 2 is provided inside the feed box 1. The conveyor 2 is provided with a conveying platform 4 that slides along the length direction of the feed box 1. The four corners of the conveying platform 4 are respectively provided with lifting balance bars 5, and the top ends of the lifting balance bars 5 are all installed at the bottom of the same support platform 6.

[0022] The conveyor 2 is provided with a guide rail for the linear sliding of the conveyor platform 4, and the conveyor 2 is also provided with a control motor 3 for driving the sliding of the conveyor platform 4. The purpose of sliding the conveyor platform 4 back and forth on the conveyor 2 is achieved by the automatic control of the control motor 3.

[0023] As attached Figure 1 As shown, guide grooves 9 are respectively provided on the inner walls on both sides of the opposite sides of the feed box 1, and vertical rods 7 are respectively extended downward on both sides of the support platform 6. The lower ends of the vertical rods 7 are provided with rollers 8, which are respectively built into the guide grooves 9 on the corresponding side and slide along them. The positions of the guide grooves 9 and the vertical rods 7 on both sides are kept aligned and in a symmetrical relationship. It should be noted that the guide groove 9 is formed into an integrated channel by two sections of horizontal and staggered straight grooves and a section of inclined groove for connecting the two sections of straight grooves. In addition, in combination with the attached Figure 1 It can be seen that the straight trough at the upper position is closer to the hopper 19, while the straight trough at the lower position is far away from the hopper 19. This design is convenient for feeding.

[0024] As the conveyor platform 4 moves back and forth, the rollers 8 at the bottom of the uprights 7 slide along the guide grooves 9. Therefore, when the rollers 8 slide from the lower straight grooves into the higher straight grooves, the four lifting balance rods 5 are stretched, raising the height of the support platform 6. As the conveyor platform 4 slides from left to right, the support platform 6 also rises. Workers can add PE plastic pellets when the support platform 6 is in the lower position and pour them out when the support platform 6 rises to the higher position.

[0025] The support platform 6 is provided with a screw mechanism 10 and a loading platform 11, and a connecting arm 17 is rotatably mounted on the screw mechanism 10:

[0026] The screw mechanism 10 includes a screw rod 14, a nut pair 16, and a motor 15. Mounting brackets 20 are provided on both sides of the table surface of the support platform 6. The two ends of the screw rod 14 are rotatably connected to the mounting brackets 20 on both sides. The nut pair 16 is sleeved on the screw rod 14 and is threadedly connected to it. The motor 15 is fixed to the mounting bracket 20 at one end and controls the transmission of the screw rod 14.

[0027] The lower end of the connecting arm 17 is rotatably mounted on the nut pair 16, and the upper end of the connecting arm 17 is rotatably mounted on the middle portion of the bottom surface of the loading platform 11;

[0028] The support platform 6 is provided with a fixing seat 18 along the edge of its rear end. A fixing shaft is provided in the fixing seat 18 . The rear end of the loading platform 11 is rotatably mounted on the fixing seat 18 via the fixing shaft.

[0029] The bottom surface of the loading platform 11 is designed as an inclined surface 12, and a certain angle is formed between the inclined surface 12 and the connecting arm 17. With such a design, the occurrence of dead angles is avoided, and it is ensured that the loading platform 11 can be pushed or pulled by the connecting arm 17 to flip over with the fixed seat 18 as the fulcrum. The table top of the loading platform 11 is designed as a plane 13, which is convenient for receiving materials and also convenient for subsequent dumping of materials. When the loading platform 11 is close to the entrance of the hopper 19, the loading platform 11 is controlled to flip over by the screw mechanism 10, so that the material on the loading platform 11 can be poured into the hopper 19. In this design, the height of the loading platform 11 can be changed. Therefore, there is no need to manually lift the bags of plastic particles to a high place and then implement the delivery, which can reduce the work intensity, and the capacity of the fully loaded loading platform 11 is fixed, and quantitative feeding can also be guaranteed. The entire feeding process saves time and effort, and can improve work efficiency.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
