Abstract
Description
Technical Field
[0001] This application relates to the technical field of plastic processing, and in particular to a feeding device for a polystyrene foam molding machine. Background Technology
[0002] Polystyrene foam is made primarily of polystyrene resin with the addition of foaming agents and other additives. It is one of the most widely used cushioning materials. Foam molding machines are a type of equipment with relatively mature technology.
[0003] Polystyrene foam molding involves adding cured polystyrene granules to a foam molding machine for heat treatment. The foam molding machines used in this process are typically quite large. Workers usually add the raw materials by pouring bags of material into the foam molding machine through multiple feeding ports on the top or other side walls. Because the foam molding machine is large, typically about 6 meters long and 2-3 meters deep, and requires adding multiple bags of material, uneven feeding may occur, leading to uneven product density. Utility Model Content
[0004] In order to improve the uniformity of raw material distribution in a foam molding machine, the purpose of this application is to provide a feeding device for a polystyrene foam molding machine.
[0005] The feeding device for a polystyrene foam molding machine provided in this application adopts the following technical solution:
[0006] A feeding device for a polystyrene foam molding machine includes a storage cylinder positioned above the foam molding machine body, a collection hopper below the storage cylinder, a distributing cone installed inside the collection hopper, and multiple guide pipes fixedly connected around the distributing cone. The openings of the guide pipes are equidistantly arranged around the axis of the distributing cone. The end of the guide pipe away from the collection hopper is positioned above the foam molding machine body and spaced apart along the length of the foam molding machine body. Multiple distributing plates are provided above the foam molding machine body, and the distributing plates are arranged along the length of the foam molding machine body, with each distributing plate corresponding to and fixedly connected to one of the guide pipes. A drive assembly is provided on the foam molding machine body to move the distributing plates on the foam molding machine body.
[0007] By adopting the above technical solution, the material can be concentrated in the storage cylinder. Then, the material in the storage cylinder can fall onto the distribution cone and be evenly distributed into each guide pipe by the distribution cone. Then, the material in the guide pipe falls onto its corresponding distribution plate for distribution. At the same time, the distribution plate can be moved by the drive component, thereby changing the landing point of the material on the foam molding machine body. This makes the distribution of material on the foam molding machine body more uniform and reduces the occurrence of uneven product density.
[0008] Optionally, the two ends of the material distribution plate extend toward one side of the foam molding machine body, and the material distribution plate is provided with multiple discharge holes.
[0009] By adopting the above technical solution, the material can leave the distribution plate through both ends of the distribution plate, and the material can fall through the discharge hole during the flow of the material on the distribution plate, thereby further improving the uniformity of the material distribution on the body of the foam molding machine.
[0010] Optionally, a surrounding plate is fixedly connected to the upper end of the material distribution plate along the edge of the material distribution plate.
[0011] By adopting the above technical solution, the material can be prevented from spilling excessively from the edge of the distribution plate during its movement on the distribution plate, thereby making the material distribution on the foam molding machine body more uniform.
[0012] Optionally, the drive assembly includes an electric telescopic rod and a connecting rod, the connecting rod being fixed between two adjacent material distribution plates, the electric telescopic rod being mounted on the body of the foam molding machine, and the telescopic end of the electric telescopic rod being fixed to the material distribution plate.
[0013] By adopting the above technical solution, one of the material distribution plates can be moved by an electric telescopic rod. As a result, multiple material distribution plates can be moved in the same direction under the action of the connecting rod, thereby changing the landing point of the material on the body of the foam molding machine.
[0014] Optionally, a slide bar is fixedly connected to the body of the foam molding machine, and the material distribution plate is slidably connected to the slide bar.
[0015] By adopting the above technical solution, the sliding direction of the material distribution plate can be limited by the slide bar, thereby improving the stability of the material distribution plate on the body of the foam molding machine.
[0016] Optionally, a slide cylinder is fixedly connected to the material distribution plate. The slide cylinder is coaxially arranged and slidably connected to the slide rod. The material distribution plate is slidably connected to the slide rod through the slide cylinder.
[0017] By adopting the above technical solution, the material distribution plate can be slidably connected to the slide rod through the slide cylinder, thereby reducing the friction between the material distribution plate and the slide rod, and thus playing a protective role between the material distribution plate and the slide rod.
[0018] Optionally, a support rod is provided on the outer wall of the hopper, one end of the support rod is fixedly connected to the outer wall of the hopper, and a limiting ring is fixedly connected to the side of the support rod away from the aggregate. The limiting ring corresponds one-to-one with the guide pipe, and the guide pipe is slidably connected inside the limiting ring.
[0019] By adopting the above technical solution, the position of the guide tube can be restricted by the limiting ring, reducing the possibility of the guide tubes abutting each other during movement.
[0020] Optionally, a protective rubber ring is fixedly attached to the inner arc surface of the limiting ring, and the outer wall of the guide tube abuts against the inner arc surface of the protective rubber ring.
[0021] By adopting the above technical solution, the protective rubber ring can protect the guide tube and the limiting ring, reducing wear on both.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. The material distribution plate can be moved by the drive component, thereby changing the landing point of the material on the foam molding machine body. This makes the material distribution on the foam molding machine body more uniform and reduces the occurrence of uneven product density.
[0024] 2. During the flow of materials on the distribution line, they can fall through the discharge hole, which can further improve the uniformity of material distribution on the body of the foam molding machine;
[0025] 3. The sliding direction of the distribution plate can be restricted by the slide bar, thereby improving the stability of the distribution plate on the body of the foam molding machine. Attached Figure Description

Detailed Implementation
[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.
[0031] An embodiment of this application is: a feeding device for a polystyrene foam molding machine, referring to... Figure 1The system includes a storage cylinder 3 positioned above the foam molding machine body 1, which is fixed within the workshop. Below the storage cylinder 3 is a collecting hopper 2, the lower end of which gradually tapers and is fitted with a distributing cone 21. The storage cylinder 3, collecting hopper 2, and distributing cone 21 are coaxially arranged.
[0032] Six guide pipes 4 are fixedly connected around the distribution cone 21. The openings of the guide pipes 4 are equidistantly arranged around the axis of the distribution cone 21 and the guide pipes 4 are fixedly connected to the collection hopper 2. The end of the guide pipe 4 away from the collection hopper 2 is placed above the foam molding machine body 1 and is spaced apart along the length of the foam molding machine body 1.
[0033] Thus, the material added into the storage cylinder 3 can fall onto the distribution cone 21, and after being diverted by the distribution cone 21, it can be evenly introduced into multiple guide pipes 4.
[0034] Reference Figure 1 and Figure 2 A slide rod 7 is fixedly connected to the body 1 of the foam molding machine. Six material distribution plates 5 are provided on the slide rod 7. Both ends of the material distribution plates 5 are inclined towards one side of the body 1 of the foam molding machine. Multiple discharge holes 51 are opened on the material distribution plates 5. In order to reduce the occurrence of material falling off the material distribution plates 5 when it falls on the edge of the material distribution plates 5, a surrounding plate 52 is fixedly connected to the upper end of the material distribution plates 5 and is arranged around the edge of the material distribution plates 5.
[0035] The material distribution plate 5 is set along the length of the foam molding machine body 1 and corresponds one-to-one with the material guide pipe 4. Two fixing rods 41 are fixedly connected to the end of the material guide pipe 4 away from the material collection hopper 2. The end of the fixing rod 41 away from the material guide pipe 4 is fixedly connected to the upper surface of the material distribution plate 5.
[0036] The material discharged through the guide pipe 4 can fall onto the distribution plate 5, and move to both ends of the distribution plate 5. During the movement, it falls into the foam molding machine body 1 through the discharge hole 51.
[0037] The foam molding machine body 1 is equipped with a drive assembly 6 for moving the material distribution plate 5 on the foam molding machine body 1.
[0038] In this embodiment, the drive assembly 6 is configured as two sets, located on both sides of the foam molding machine body 1 respectively. Each set of drive assembly 6 includes two electric telescopic rods 61 and four connecting rods 62. The connecting rods 62 are fixedly connected between two adjacent material distribution plates 5. The electric telescopic rods 61 are installed on the foam molding machine body 1. The telescopic end of the electric telescopic rod 61 is fixedly connected to the material distribution plate 5 on the side closest to the electric telescopic rod 61.
[0039] Thus, one of the material distribution plates 5 can be moved by the electric telescopic rod 61, thereby causing multiple material distribution plates 5 to move synchronously, thereby changing the landing point of the material on the foam molding machine body 1. At the same time, in order to protect the material distribution plate 5, a slide cylinder 8 is fixedly connected to the lower end of the material distribution plate 5. The slide cylinder 8 is coaxially arranged and slidably connected to the slide rod 7, and the material distribution plate 5 is slidably connected to the slide rod 7 through the slide cylinder 8.
[0040] Reference Figure 1 and Figure 3 To reduce wear between the feed pipes 4, a support rod 9 is provided on the outer wall of the hopper 2. One end of the support rod 9 is fixedly connected to the outer wall of the hopper 2, and a limit ring 91 is fixedly connected to the end of the support rod 9 away from the hopper 2. The limit ring 91 corresponds one-to-one with the feed pipe 4. A protective rubber ring 92 is fixedly connected to the inner arc surface of the limit ring 91. The outer wall of the feed pipe 4 abuts against and slides with the inner arc surface of the protective rubber ring 92.
[0041] The implementation principle of this application embodiment is as follows: When feeding material into the foam molding machine body 1, the material is placed in the storage cylinder 3 for concentration. Then, the material in the storage cylinder 3 can fall onto the distribution cone 21 and fall evenly into each guide pipe 4 through the distribution cone 21. Then, the material in the guide pipe 4 falls onto the corresponding distribution plate 5 for distribution and falls into the foam molding machine body 1 through the discharge hole 51. At the same time, the distribution plate 5 can be moved by starting the electric telescopic rod 61, thereby changing the landing point of the material on the foam molding machine body 1.
[0042] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
