Description

Technical Field

[0001] This utility model relates to the field of plastic granule technology, specifically to an automatic switching device for positive pressure feeding. Background Technology

[0002] Plastic granules refer to granular plastics, generally classified into over 200 types, with further subdivisions reaching thousands. Common plastic granules include general-purpose plastics, engineering plastics, and specialty plastics. General-purpose plastics include: polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, and polyurethane. Engineering plastics include: nylon, polytetrafluoroethylene, polyoxymethylene, and polycarbonate. Specialty plastics include: thermosetting plastics and functional polymer plastics, such as artificial kidneys.

[0003] In the past, the plastics industry relied on two main methods for transporting granular raw materials: manual handling and pneumatic conveying via pipelines with manual selection of the pipeline. Manual handling was inefficient and relatively expensive. Manual pipeline selection for pneumatic conveying was prone to errors, leading to waste of raw materials due to human error, and even rendering the materials unusable, while also being inefficient. To address these issues, a positive pressure feeding automatic switching device was invented. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic switching device for positive pressure feeding, so as to solve the problem mentioned in the background art, which can improve conveying efficiency and save costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positive pressure feeding automatic switching device, comprising a base plate, on which multiple discharge pipes are installed, and two electric slide rails are installed on the top of the base plate. An electric slide plate is slidably connected to the top of the electric slide rails. A drive assembly is provided between the two electric slide rails. A connecting plate is fixedly connected to the top of each of the two electric slide plates. A platform plate is installed between the two connecting plates. A discharge plate is movably installed at the bottom of the platform plate. A discharge hopper is installed through the discharge plate.

[0006] Preferably, the drive assembly includes a stepper motor, the output end of which is fixedly mounted with a drive shaft. One end of the drive shaft passes through the outer wall of two electric slide rails and is movably connected to the outer wall of the two electric slide rails. Two connectors are mounted on the outside of the drive shaft, and the two connectors are respectively mounted on the two electric slide rails.

[0007] Preferably, a motor mount is installed on the outside of the stepper motor, and the motor mount is fixedly connected to the outer wall of the electric slide rail.

[0008] Preferably, the bottom of the electric slide rail is fixedly equipped with multiple fixing seats, and the multiple fixing seats are all installed on the top of the base plate.

[0009] Preferably, two guide plates are installed at the bottom of the platform plate, and guide rails are slidably connected to the bottom of each guide plate. Both guide rails are installed on the top of the base plate.

[0010] Preferably, a plurality of cylinders are installed on the top of the platform plate, and the bottom of each of the plurality of cylinders penetrates through the platform plate and is fixedly connected to the top of the feeding plate.

[0011] Preferably, the inner diameter of the top of the hopper is larger than the inner diameter of the bottom, and the inner diameter of the bottom of the hopper is smaller than the inner diameter of the discharge pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Equipped with cylinders, electric slide rails, and electric sliding plates, when plastic granules need to be transported, workers can control the drive of the electric slide rails via an external controller. This causes the two electric slide rails to drive two electric sliding plates to move horizontally. The electric sliding plates then drive the corresponding connecting plates to move. The two connecting plates together drive the platform plate to move. The platform plate then drives two guide plates on it to slide on the guide rails. Simultaneously, the platform plate also drives multiple sets of cylinders, a feeding plate, and a feeding hopper to move. After the feeding hopper moves to the top of the appropriate feeding pipe, it drives multiple sets of cylinders to move the feeding plate together. The feeding plate then drives the feeding hopper to embed into the feeding pipe for subsequent feeding operations. Through the above steps, manual handling and manual pipe selection can be replaced, avoiding losses caused by human factors. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a positive pressure feeding automatic switching device, including a base plate 1, on which multiple feeding pipes 2 are installed, and two electric slide rails 4 are installed on the top of the base plate 1. Electric slide plates 8 are slidably connected to the top of the electric slide rails 4. A drive component is provided between the two electric slide rails 4. A connecting plate 9 is fixedly connected to the top of each of the two electric slide plates 8. A platform plate 10 is installed between the two connecting plates 9. A feeding plate 14 is movably installed at the bottom of the platform plate 10. A feeding hopper 15 is installed through the feeding plate 14.

[0022] Please see Figure 2 and Figure 4 The drive assembly includes a stepper motor 5, with a drive shaft 6 fixedly mounted on the output end of the stepper motor 5. One end of the drive shaft 6 passes through the outer wall of two electric slide rails 4 and is movably connected to the outer wall of the two electric slide rails 4. Two connectors 7 are mounted on the outside of the drive shaft 6, and the two connectors 7 are respectively mounted on the two electric slide rails 4. When it is necessary to change the position of components such as the feed plate 14 and the feed hopper 15, the stepper motor 5 can be driven, causing the stepper motor 5 to drive the drive shaft 6 to rotate. The drive shaft 6 drives the two connectors 7 to rotate, and the two connectors 7 respectively drive the two sets of electric slide rails 4, so that the two sets of electric slide rails 4 respectively drive the corresponding electric slide plate 8 to move for subsequent operations.

[0023] Please see Figure 1 A motor mount 16 is installed on the outside of the stepper motor 5. The motor mount 16 is fixedly connected to the outer wall of the electric slide rail 4. The motor mount 16 makes the stepper motor 5 more stable when driven, avoiding the problem of instability of the stepper motor 5.

[0024] Please see Figure 1 and Figure 3 Multiple mounting bases 3 are fixedly installed at the bottom of the electric slide rail 4. All mounting bases 3 are installed on the top of the base plate 1. By using multiple sets of mounting bases 3, the electric slide rail 4 is fixed to the base plate 1, ensuring the smooth operation of the entire equipment in the future.

[0025] Please see Figure 4 and Figure 5The platform plate 10 has two guide plates 12 installed at the bottom. The bottom of each guide plate 12 is slidably connected to a guide rail 13. Both guide rails 13 are installed on the top of the base plate 1. By using the cooperation of the two sets of guide rails 13 and the two sets of guide plates 12, the horizontal movement trajectory of components such as the platform plate 10, the feeding plate 14 and the feeding hopper 15 is limited.

[0026] Please see Figure 5 Multiple cylinders 11 are installed on the top of the platform plate 10. The bottom of each cylinder 11 passes through the platform plate 10 and is fixedly connected to the top of the feeding plate 14. By using the multiple cylinders 11, the feeding plate 14 can be pushed downward when driven by the multiple cylinders 11, so that the feeding hopper 15 on the feeding plate 14 is embedded inside the feeding pipe 2, thus completing the action of selecting the feeding pipe 2.

[0027] Please see Figure 3 and Figure 5 The top inner diameter of the hopper 15 is larger than the bottom inner diameter, and the bottom inner diameter of the hopper 15 is smaller than the inner diameter of the discharge pipe 2. This setting allows the hopper 15 to be smoothly embedded inside the discharge pipe 2, avoiding the problem of plastic particles leaking during material conveying.

[0028] Working principle: When using this application, the entire equipment is first installed in a suitable position. When it is necessary to transport plastic granules, the operator can control the drive of the electric slide rail 4 on the external controller, so that the two electric slide rails 4 drive the two electric slide plates 8 to move horizontally. The electric slide plates 8 drive the corresponding connecting plates 9 to move. The two connecting plates 9 together drive the platform plate 10 to move. The platform plate 10 drives the two guide plates 12 on it to slide on the guide rail 13. At the same time, the platform plate 10 also drives multiple sets of cylinders 11, the feeding plate 14 and the feeding hopper 15 to move. After the feeding hopper 15 moves to the top of the suitable feeding pipe 2, the multiple sets of cylinders 11 are driven, so that the multiple sets of cylinders 11 together drive the feeding plate 14 to move. The feeding plate 14 drives the feeding hopper 15 to embed into the feeding pipe 2 for subsequent feeding operations. Through the above steps, it can replace manual handling and manual selection of pipes, avoiding losses caused by human factors.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
