Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a PVC film raw material mixing device. Background Technology

[0002] PVC film is made of a variety of raw materials. These materials must be thoroughly mixed by a mixing device and then processed into film using a calendering process.

[0003] In existing technologies, mixing devices typically employ a horizontal mixing tank design with an opening at the top. Operators manually lift the bagged raw materials and then drop them into the mixing tank. During the feeding process, due to the lack of a supporting structure, the bagged raw materials usually need to simply rest against the mixing tank, making it difficult to evenly distribute the raw materials within the tank. Therefore, it is essential to design a PVC film raw material mixing device. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a PVC film raw material mixing device.

[0005] The objective of this utility model can be achieved through the following technical solution: A PVC film raw material mixing device includes a base, on which a mixing box with an opening at the top is installed. The mixing box is elongated and a cover that can close the opening is hinged to the mixing box. A stirring shaft is horizontally rotatably installed on the base and passes into the mixing box. Several stirring blades are installed on the stirring shaft. Two tracks are also horizontally installed on the mixing box, and the tracks are close to the opening. A movable mesh platform is slidably connected between the tracks. A retractable placement rack is also horizontally slidably connected to the movable mesh platform.

[0006] A power motor is mounted on the base, and the output shaft of the power motor is horizontally set. The end of the output shaft of the power motor is connected to a pulley one. A pulley two is mounted on the end of the stirring shaft, and a belt is provided between the pulley two and the pulley one.

[0007] The retractable placement rack has gripping openings.

[0008] The retractable rack is made of multiple welded rods.

[0009] A power cylinder is also provided between the box cover and the mixing box.

[0010] The mixing chamber is mounted on the base by multiple fasteners.

[0011] A control box is also installed on the base, and the power motor and power cylinder are both connected to the control box.

[0012] Compared with existing technologies, this PVC film raw material mixing device has the following advantages:

[0013] In this invention, by setting up a movable mesh platform, bagged raw materials can be placed on the movable mesh platform. The movable mesh platform can move the bagged raw materials, thereby conveniently and evenly adding the raw materials into the mixing box. In addition, for bagged raw materials with larger volume, the retractable placement rack can be pulled outward accordingly to provide sufficient placement space for the bags during the feeding process.

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figures 1-2 As shown, this PVC film raw material mixing device includes a base 1, on which a mixing box 4 with an opening at the top is installed. Specifically, the mixing box 4 is installed on the base 1 by multiple fixing parts 14; the mixing box 4 is elongated, and a discharge pipe 5 is located at the bottom of the mixing box 4, with a valve on the discharge pipe 5; a box cover 11 that can close the opening is hinged to the mixing box 4; a stirring shaft 15 is horizontally rotatably installed on the base 1, and the stirring shaft 15 passes into the mixing box 4; several stirring blades 10 are installed on the stirring shaft 15; and two tracks are also horizontally installed on the mixing box 4. 12, and the track 12 is close to the opening, and a movable mesh platform 13 is slidably connected between the tracks 12. A retractable placement rack 3 is also horizontally slidably connected on the movable mesh platform 13; locking screws 17 for locking the retractable placement rack 3 are also threaded on both sides of the movable mesh platform 13; with this structure, when the bag containing the raw materials is large, the retractable placement rack 3 can be pulled out; when the bag containing the raw materials is small, it can simply be placed on the movable mesh platform 13, and the raw materials in the bag can be poured out and added into the mixing box 4 by the operator's manual action.

[0019] A power motor 6 is installed on the base 1, and the output shaft of the power motor 6 is set horizontally. The end of the output shaft of the power motor 6 is connected to pulley 7. A second pulley 9 is installed at the end of the stirring shaft 15, and a belt 8 is provided between pulley 9 and pulley 7.

[0020] The retractable shelf 3 has a gripping opening 3a.

[0021] The retractable storage rack 3 is welded together from multiple rods 301.

[0022] There is also a power cylinder 16 between the cover 11 and the mixing box 4. The power cylinder 16 is an existing product that can open or close the cover 11.

[0023] The base 1 is also equipped with a control box 2. The power motor 6 and the power cylinder 16 are both connected to the control box 2. This adopts existing technology. The start and stop of the power motor 6 and the power cylinder 16 can be controlled through the control box 2.
