Description

Technical Field

[0001] This utility model relates to the field of plastic container production technology, and in particular to a feeding device for the production of plastic packaging containers. Background Technology

[0002] Plastic packaging containers are packaging containers made from plastic as raw material, through a series of processes such as batching, heating, container preforming, and blow molding.

[0003] In the production of plastic packaging containers, different colored plastic masterbatches are added and mixed to produce containers of different colors depending on the usage requirements. Existing plastic packaging container production equipment is inconvenient in two ways: firstly, it's difficult to change the color of the plastic masterbatches fed into the mixing tank; secondly, the process of quantitatively feeding different batches of plastic masterbatches into the mixing tank via a feeding tank has low continuity, thus affecting the production efficiency of plastic packaging containers. Therefore, we propose a feeding device for plastic packaging container production. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a feeding device for the production of plastic packaging containers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a feeding device for the production of plastic packaging containers, comprising a mixing tank, an inlet pipe fixedly installed at the center of the upper surface of the mixing tank, an outlet pipe fixedly installed on the bottom surface of the mixing tank, and multiple support legs fixedly installed on the bottom surface of the mixing tank around the outlet pipe. An electric telescopic rod is rotatably installed on the upper surface of the mixing tank on one side of the inlet pipe. Multiple extension frames are fixedly installed at the output end of the electric telescopic rod. A feeding tank is provided at the end of the extension frames. A connecting frame is fixedly installed on the upper surface of the feeding tank, and the end of the extension frame is fixedly connected to the connecting frame. A clearance ring is fixedly installed on the feeding tank, and a control block is slidably installed at the lower end of the feeding tank below the clearance ring. A discharge port is opened through the bottom surface of the feeding tank.

[0006] Preferably, a cross is fixedly installed at the upper part of the mixing tank, a drive motor is fixedly installed at the center of the cross, an impact plate is fixedly installed at the output end of the drive motor, multiple ventilation holes are opened through the impact plate, and multiple fan blades are rotatably installed on the upper surface of the cross below the impact plate.

[0007] Preferably, the output end of the drive motor is fixedly mounted with a drive gear below the impact disc, and the upper surface of the cross is rotatably mounted with driven gears that mesh with the drive gears below multiple fan blades, and the fan blades are fixedly connected to the center position of the driven gears.

[0008] Preferably, a push rod is fixedly installed on the upper end face of the impact disc, and the end of the push rod extends above the upper end face of the feed pipe.

[0009] Preferably, a suction fan is fixedly installed on the outer wall of the feed pipe, and the number of suction fans is two, which are symmetrically arranged on both sides of the feed pipe.

[0011] Preferably, the lower end of the feeding tank is stepped, and the control block is configured to match the shape of the lower end of the feeding tank.

[0012] Beneficial effects

[0013] This utility model provides a feeding device for the production of plastic packaging containers. It has the following beneficial effects:

[0014] (1) The feeding device for the production of plastic packaging containers can control the feeding tank containing plastic masterbatch of different colors to move to the top of the feeding pipe to feed the inside of the mixing tank through the electric telescopic rod. Under the interaction of the top rod and the control block in the feeding tank, the plastic masterbatch can be automatically discharged after the feeding tank and the mixing tank are connected. When the plastic masterbatch in the feeding tank is discharged, it is reset under the action of its own gravity. By feeding the inside of the mixing tank through multiple feeding tanks, the feeding efficiency can be continuously improved. Different colored plastic masterbatch can also be fed into the inside of the mixing tank according to the actual situation.

[0015] (2) The feeding device for the production of plastic packaging containers, when the plastic masterbatch enters the feed pipe, it first collides with the rotating impact plate. When the plastic masterbatch collides with the impact plate, the dust attached to its outer wall can be separated from the masterbatch. Multiple continuously rotating crosses are set at the bottom of the impact plate, so that the crosses can blow the light dust upward, so that the dust is separated from the plastic masterbatch, making the plastic masterbatch that enters the mixing tank for mixing cleaner.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-6As shown, a feeding device for the production of plastic packaging containers includes a mixing tank 1. A feed pipe 2 is fixedly installed at the center of the upper surface of the mixing tank 1. A discharge pipe 10 is fixedly installed on the bottom surface of the mixing tank 1. Multiple support legs 7 are fixedly installed on the bottom surface of the mixing tank 1 around the discharge pipe 10. An electric telescopic rod 4 is rotatably installed on the upper surface of the mixing tank 1 on one side of the feed pipe 2. Multiple extension frames 5 are fixedly installed at the output end of the electric telescopic rod 4. A feeding tank 6 is provided at the end of the extension frame 5. A connecting frame 17 is fixedly installed on the upper surface of the feeding tank 6. The end of the extension frame 5 is fixedly connected to the connecting frame 17. A relief ring 18 is fixedly installed on the feeding tank 6. A control block 19 is slidably installed at the lower end of the feeding tank 6 below the relief ring 18. A discharge port 20 is opened through the bottom surface of the feeding tank 6.

[0027] Users can inject plastic masterbatch granules of different colors into the feeding tank 6. By raising the extension end of the electric telescopic rod 4, the three feeding tanks 6 can be raised as a whole. Then, by rotating the electric telescopic rod 4, the feeding tank 6 of the corresponding color is moved above the feed pipe 2. Then, by lowering the extension end of the electric telescopic rod 4, the stepped lower end of the feeding tank 6 can be installed on the upper end of the feed pipe 2. During the descent of the feeding tank 6, the control block 19 inside the discharge port 20 moves upward, so the plastic masterbatch inside the feeding tank 6 can fall into the feed pipe 2 through the gap between the control block 19 and the bottom surface of the feeding tank 6. The setting of multiple feeding tanks 6 can be used to feed plastic masterbatch of different colors into the mixing tank 1.

[0028] like Figure 3 As shown, a cross 12 is fixedly installed at the upper part of the interior of the mixing tank 1. A drive motor is fixedly installed at the center of the cross 12. An impact plate 13 is fixedly installed at the output end of the drive motor. Multiple ventilation holes 11 are opened through the impact plate 13. Multiple fan blades 15 are rotatably installed on the upper surface of the cross 12 below the impact plate 13. When the plastic masterbatch falls into the interior of the mixing tank 1, it will first collide with the high-speed rotating impact plate 13. The impact can separate the dust on the outer wall of the plastic masterbatch. At the same time, under the action of multiple high-speed rotating fan blades 15, the separated dust can be blown upward to prevent the dust from re-adhering to the outer wall of the plastic masterbatch.

[0029] like Figure 4As shown, the output end of the drive motor is located below the impact disk 13 and a drive gear 16 is fixedly installed. The upper surface of the cross 12 is located below multiple fan blades 15 and a driven gear 14 is rotatably installed and meshed with the drive gear 16. The fan blades 15 and the driven gears 14 are fixedly connected at their center positions. When the drive motor drives the impact disk 13 to rotate, it can simultaneously drive the drive gear 16 to rotate. The drive gear 16 meshes with multiple driven gears 14, which can cause the multiple fan blades 15 fixedly connected to the driven gears 14 to rotate. When the fan blades 15 rotate, they can blow air upwards, which can further separate the dust on the plastic masterbatch from the plastic masterbatch.

[0030] like Figure 3 As shown, a push rod 9 is fixedly installed on the upper end face of the impact plate 13, and the end of the push rod 9 extends to a height higher than the upper end face of the feed pipe 2. The push rod 9 can push the control block 19 located inside the feed tank 6 upward when the lower end of the feed tank 6 is connected to the upper end of the feed pipe 2, thereby facilitating the discharge of the plastic masterbatch contained inside the feed tank 6.

[0031] like Figure 3 As shown, two suction fans 3 are fixedly installed on the outer wall of the feed pipe 2 and are symmetrically arranged on both sides of the feed pipe 2. The two suction fans 3 can suck up the dust inside the feed pipe 2 to prevent the dust after separation from the plastic masterbatch from re-adhering to the plastic masterbatch.

[0032] like Figure 3 As shown, a through groove is provided on the outer wall of the feed pipe 2 at the position corresponding to the suction fan 3, and a filter screen 8 is fixedly installed inside the through groove; the filter screen 8 can prevent the suction force generated by the suction fan 3 from sucking the plastic masterbatch into the interior of the suction fan 3.

[0033] like Figure 5 and Figure 6 As shown, the lower end of the feeding tank 6 is stepped, and the control block 19 is matched with the shape of the lower end of the feeding tank 6; the side wall of the control block 19 is provided with rounded corners, which makes it easier for the plastic masterbatch to move in the gap between the control block 19 and the inner wall of the bottom surface of the feeding tank 6.

[0034] The working principle of this utility model is as follows: During use, the user can inject plastic masterbatch granules of different colors into the feeding tank 6. The electric telescopic rod 4 is raised by extending its telescopic end, lifting all three feeding tanks 6 upwards. Then, rotating the electric telescopic rod 4 moves the corresponding colored feeding tank 6 above the feed pipe 2. Next, lowering the electric telescopic rod 4 lowers the stepped lower end of the feeding tank 6, which is then installed on the upper end of the feed pipe 2. During the descent of the feeding tank 6, the top rod 9, fixedly installed on the upper surface of the impact plate 13, pushes the control block 19 upwards through the discharge port 20. The plastic masterbatch inside the feeding tank 6 then falls into the feed pipe 2 through the discharge port 20 via the gap between the control block 19 and the bottom surface of the feeding tank 6. Inside the mixing tank 1, when the plastic masterbatch enters the feed pipe 2, it first collides with the rotating impact plate 13. When the plastic masterbatch collides with the impact plate 13, the dust attached to its outer wall can be separated from the masterbatch. At the bottom of the impact plate 13, there are multiple continuously rotating crosses 12. The crosses 12 can blow the light dust upwards, so that the dust is separated from the plastic masterbatch. Two suction fans 3 located on both sides of the feed pipe 2 can collect the dust. This process continues, which can make the plastic masterbatch entering the mixing tank 1 for mixing cleaner. At the same time, the electric telescopic rod 4 located on the upper surface of the mixing tank 1 can be rotated to replace the feeding tank 6, thereby feeding masterbatch of different colors into the mixing tank 1 for mixing.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
