Description

Technical Field

[0001] This utility model relates to the field of mixer technology, specifically to a horizontal mixer for processing plastic products. Background Technology

[0002] In the processing of plastic products, the uniform mixing of raw materials is a crucial step in ensuring the stable quality and excellent performance of the final product. Plastic raw materials typically include various components such as base resin, additives, and fillers. These materials need to be thoroughly mixed under specific temperature and time conditions to ensure the consistency of their physical and chemical properties. Horizontal mixers, as a commonly used mixing device, are widely used in the plastics industry for the preliminary mixing and homogenization of materials. They are simple in structure, easy to operate, and have high mixing efficiency, making them suitable for the premixing processes of various plastic raw materials.

[0003] However, existing horizontal mixers still have some technical defects in practical applications. Because the mixing shaft and blades of traditional equipment are mostly fixed and have a single structural design, they are difficult to adapt to the diverse characteristics of materials. This leads to uneven mixing of materials during the mixing process, especially when processing high-viscosity substances or large particles. The mixing effect is significantly reduced, the materials are not fully dispersed and uniformly mixed, and the final product may have unstable quality. Therefore, we propose a horizontal mixer for plastic product processing to overcome the above defects. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a horizontal mixer for processing plastic products.

[0005] The technical solution is as follows: A horizontal mixer for processing plastic products includes a base, a frame, and a mixing chamber. The base serves as the assembly carrier for the mixer, and the frame is fixedly connected to the base. The mixing chamber is fixedly installed on the upper part of the frame, and a feed inlet is provided at the top of the mixing chamber. A chamber cover is hinged to the feed inlet of the mixing chamber. The mixer also includes a motor, a mixing shaft, a first spiral mixing blade, a second spiral mixing blade, and a discharge chamber door. The bottom of the mixing chamber is a semi-circular chamber body, and the mixing shaft is rotatably connected to the center of the semi-circular chamber body. The stirring shaft is fixedly equipped with a first spiral stirring blade and a second spiral stirring blade. The first spiral stirring blade is located around the second spiral stirring blade, and the spiral directions of the first spiral stirring blade and the second spiral stirring blade are opposite. A motor is fixedly installed on the outer wall of the mixing chamber shell. The output shaft of the motor is connected to the stirring shaft. A discharge chamber door is hinged at the bottom discharge port of the mixing chamber. The discharge chamber door is sealed and closed at the discharge port of the mixing chamber. The base is provided with a drive component that drives the discharge chamber door to open and close at the discharge port of the mixing chamber.

[0006] Furthermore, the driving component includes an electric push rod, a slide rail, a connecting rod, and a pulley. Two electric push rods are fixedly installed on the base. A slide rail is fixedly connected to the piston rod of the electric push rod. Connecting rods are symmetrically fixedly connected to the outer wall of the discharge hopper door. A pulley is rotatably installed on the side of the connecting rod closest to the electric push rod. The pulley is located in the middle of the slide rail on the same side.

[0007] Furthermore, a sealing gasket is provided on the inner side of the discharge hopper door, and a groove adapted to the sealing gasket is provided in the hopper body near the discharge port of the mixing hopper, and the sealing gasket is embedded in the groove of the mixing hopper.

[0008] Furthermore, contact blocks are symmetrically fixedly connected to both sides of the outer wall of the discharge hopper door, and an inclined discharge hopper is fixedly installed at the bottom of the mixing chamber shell. Locking fasteners for locking the discharge hopper door are provided on both sides of the discharge hopper.

[0009] Furthermore, the locking component includes a support plate, a wedge block, and a contact plate. The support plate is fixedly connected to both sides of the discharge hopper. The wedge block is slidably connected to the support plate via a guide rod. The wedge block contacts and latches onto the contact block on the outer wall of the discharge hopper door. A contact plate is fixedly installed at the end of the guide rod away from the wedge block. A spring is sleeved on the guide rod between the support plate and the wedge block.

[0010] Furthermore, an electric push rod two is fixedly installed on the side of the frame near the locking component. The electric push rod two is inclined and its piston rod and contact plate are in contact with each other.

[0011] The beneficial effects are:

[0012] 1. This utility model, by assembling two spiral stirring blades with opposite spiral directions on the stirring shaft, can achieve bidirectional stirring of plastic raw materials, generate complex flow patterns, help break up the agglomeration between materials, and thus significantly improve the mixing uniformity and stirring efficiency of materials.

[0013] 2. This utility model can automate the material discharge process by designing an automatic opening and closing mechanism for the discharge bin door, thereby reducing the need for manual operation of opening and closing the discharge bin door, improving production efficiency and reducing labor costs.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0022] A horizontal mixer for processing plastic products, such as Figures 1-3As shown, the mixer includes a base 1, a frame 101, and a mixing chamber 2. The base 1 serves as the assembly carrier for the mixer, and the frame 101 is fixedly connected to the base 1. The mixing chamber 2 is fixedly installed on the upper part of the frame 101. The top of the mixing chamber 2 has a feed inlet, and a chamber cover 3 is hinged to the feed inlet of the mixing chamber 2. The mixer also includes a motor 4, a mixing shaft 5, a first spiral mixing blade 6, a second spiral mixing blade 7, and a discharge chamber door 8. The bottom of the mixing chamber 2 is a semi-circular chamber body. The mixing shaft 5 is rotatably connected to the center of the semi-circular chamber body of the mixing chamber 2. The first spiral mixing blade 6 and the second spiral mixing blade 7 are fixedly mounted on the mixing shaft 5. The first spiral mixing blade 6 is located around the second spiral mixing blade 7, and the spiral mixing blade 6... The first stirring blade 6 and the second spiral stirring blade 7 have opposite spiral directions. A motor 4 is fixedly installed on the outer wall of the mixing chamber 2. The output shaft of the motor 4 is connected to the stirring shaft 5. A discharge chamber door 8 is hinged at the bottom discharge port of the mixing chamber 2. The discharge chamber door 8 is sealed and closed at the discharge port of the mixing chamber 2. A drive component is provided on the base 1 to drive the discharge chamber door 8 to open and close at the discharge port of the mixing chamber 2. After the plastic raw material is added into the mixing chamber 2, the stirring shaft 5 is driven to rotate by the motor 4. The first spiral stirring blade 6 and the second spiral stirring blade 7 on the stirring shaft 5 will perform bidirectional stirring of the plastic raw material and generate a complex flow pattern, which helps to break the agglomeration between materials, thereby improving the mixing uniformity and efficiency of the materials.

[0023] like Figure 1 and Figure 4 As shown, the driving components include an electric push rod 10, a slide rail 11, a connecting rod 12, and a pulley 13. Two electric push rods 10 are fixedly installed on the base 1. The slide rail 11 is fixedly connected to the piston rod of the electric push rod 10. The connecting rod 12 is symmetrically fixedly connected to the outer wall of the discharge hopper door 8. The pulley 13 is rotatably installed on the side of the connecting rod 12 near the electric push rod 10. The pulley 13 is located in the middle of the slide rail 11 on the same side. The electric push rod 10 drives the slide rail 11 to rise and fall and pushes the pulley 13. While the pulley 13 slides in the slide rail 11, the connecting rod 12 drives the discharge hopper door 8 to automatically open and close at the discharge port of the mixing chamber 2, saving the manual operation of opening and closing the discharge hopper door 8.

[0024] like Figure 4 As shown, a sealing gasket 81 is provided on the inner side of the discharge hopper door 8, and a groove adapted to the sealing gasket 81 is provided in the body of the mixing chamber 2 near the discharge port. The sealing gasket 81 is embedded in the groove of the mixing chamber 2. The sealing gasket 81 is used to improve the sealing performance of the discharge hopper door 8 covering the discharge port of the mixing chamber 2.

[0025] like Figure 1As shown, contact blocks 14 are symmetrically fixedly connected to both sides of the outer wall of the discharge hopper door 8. An inclined discharge hopper 9 is fixedly installed at the bottom of the outer shell of the mixing chamber 2. Locking fasteners for locking the discharge hopper door 8 are provided on both sides of the discharge hopper 9. The locking fasteners ensure that the discharge hopper door 8 is stably covered on the mixing chamber 2 by limiting the contact blocks 14.

[0026] like Figure 1 and Figure 5 As shown, the locking mechanism includes a support plate 15, a wedge block 16, and a contact plate 162. The support plate 15 is fixedly connected to both sides of the discharge hopper 9. The wedge block 16 is slidably connected to the support plate 15 via a guide rod 161. The wedge block 16 contacts and latches onto the contact block 14 on the outer wall of the discharge hopper door 8. The end of the guide rod 161 away from the wedge block 16 is fixedly provided with a contact plate 162. A spring 17 is sleeved on the guide rod 161 between the support plate 15 and the wedge block 16. The wedge block 16 latches onto the contact block 14 under the action of the spring 17.

[0027] like Figure 5 As shown, an electric push rod 18 is fixedly installed on the side of the frame 101 near the locking component. The electric push rod 18 is inclined and its piston rod is in contact with the contact plate 162. The piston rod of the electric push rod 18 extends and pushes the contact plate 162, so that the contact plate 162 drives the wedge block 16 to automatically disengage from the locking of the contact block 14 through the guide rod 161.

[0028] The operator first opens the top cover 3 of the mixing chamber 2, adds the plastic raw material into the mixing chamber 2 through the feed inlet, then closes the cover 3, and then starts the motor 4. The motor 4 drives the spiral mixing blades 6 and 7 on the mixing shaft 5 to rotate synchronously with opposite spiral directions. During the rotation, the two sets of opposite spiral mixing blades exert complex forces on the material, generating strong convection and shear effects, effectively breaking up material agglomeration and achieving rapid and uniform mixing of the various components of the plastic raw material. After mixing is completed, the operator starts the electric push rod 18. The piston rod of the electric push rod 18 extends and pushes the contact plate 162. The contact plate 162 drives the guide rod 161 to overcome the force of the spring 17, causing the wedge block 16 to move backward, automatically releasing the mechanical lock on the contact block 14 on the outer wall of the discharge chamber door 8. Then, the two electric push rods 10 on the base 1 are started. The piston rods of the electric push rods 10 extend and drive the slide rail 11 to rise, and the slide rail 11 rises. The rail 11 presses upward against the pulley 13 on the connecting rod 12, forcing the connecting rod 12 and the discharge hopper door 8 to rotate upward around the hinge point, automatically opening the discharge hopper door 8. The uniformly mixed plastic raw material is then smoothly discharged through the inclined discharge hopper 9 at the bottom of the mixing chamber 2 under the action of gravity. After the discharge is completed, the electric push rod 10 is activated again to shorten its piston rod and push the slide rail 11 downward. The slide rail 11 pulls the discharge hopper door 8 downward through the pulley 13 and the connecting rod 12, so that the discharge hopper door 8 can tightly cover the discharge port. At this time, the sealing gasket 81 on the inner side of the discharge hopper door 8 automatically embeds into the groove around the discharge port of the mixing chamber 2 to form a reliable seal. At the same time, the electric push rod 18 resets and disengages from the contact plate 162. The spring 17 pushes the guide rod 161 to reset the wedge block 16 and re-lock the contact block 14, firmly locking the discharge hopper door 8 in the closed position. The equipment completes one working cycle and is ready for the next mixing operation.
