Abstract
Description
Technical Field
[0001] This utility model relates to the field of PVC processing technology, specifically to a mixing and stirring device for PVC composite materials. Background Technology
[0002] Polyvinyl chloride, or PVC for short, is the world's third-largest synthetic polymer plastic produced (after polyethylene and polypropylene), with an annual production of approximately 40 million tons. PVC is a polymer formed by the polymerization of vinyl chloride monomer (VCM) through a free radical polymerization mechanism under the action of initiators such as peroxides and azo compounds, or under the influence of light and heat.
[0003] PVC resin is a white or light yellow powder that cannot be used alone and must be modified. Different additives, such as plasticizers, stabilizers, lubricants, and colorants, are added depending on the intended use, and these must be thoroughly mixed.
[0004] Therefore, a mixing and stirring device for PVC composite materials is proposed. Summary of the Invention
[0005] The purpose of this invention is to provide a mixing and stirring device for PVC composite materials to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A mixing and stirring device for PVC composite materials includes a base, a support column and a mixing bowl, wherein a connecting rod is provided at the bottom end of the mixing bowl and a worm gear is provided around the body of the connecting rod; The connecting rod is rotatably connected to the top of the support column; The top of the support column is provided with a drive structure that works in conjunction with a worm gear. A support frame is provided on one side of the support column, and a transmission structure is provided at one end of the support frame for rotatable connection. A stirring part is provided at one end of the transmission structure for rotatable connection, and the curved part at the front end of the stirring part extends into the interior of the stirring basin.
[0007] Furthermore, the top of the support column is provided with a slot, and a bearing is installed inside the slot. The connecting rod is inserted into the slot and is interference-fitted with the bearing.
[0008] Furthermore, the drive structure consists of a worm gear and a motor. The worm gear is connected to a support column via a mounting base, and one end of the worm gear is connected to the output end of the motor.
[0009] Furthermore, the worm gear meshes with the worm wheel.
[0010] Furthermore, the transmission structure includes a lower rod, two connecting rods, and an auxiliary rod; The lower rod is hinged to the bottom corner of the support frame. One end of each of the two connecting rods is hinged to one end and two-thirds of the lower rod, respectively, and the other end is hinged to the stirring part. One end of the auxiliary rod is hinged to the protruding part of the support frame, and the other end is hinged to the stirring part.
[0011] Compared with the prior art, the beneficial effects of this utility model are: Compared with traditional manual stirring, this invention is more efficient and produces more uniform stirring and mixing. The design, which combines a drive structure with a worm gear, allows the mixing bowl to rotate autonomously. The mixing is achieved by using a stirring section that extends into the interior of the mixing bowl, saving manpower and costs. Attached Figure Description
[0012] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the drive structure of this utility model; Figure 3 This is a schematic diagram of the stirring section of this utility model. Detailed Implementation
[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example
[0014] Please see Figure 1-3 This utility model provides a technical solution: A mixing device for PVC composite materials includes a base 4, a support column 5, and a mixing bowl 1. A connecting rod 2 is provided at the bottom of the mixing bowl 1, and a worm gear 3 is provided on the ring of the connecting rod 2. In order to perform the mixing function, the connecting rod 2 is rotatably connected to the top of the support column 5, so that the mixing bowl 1 can rotate. In order to drive the mixing bowl 1 to rotate autonomously, a drive structure that works with the worm gear 3 is installed at the top of the support column 5, and the driving structure drives the mixing bowl 1. A support frame 6 is installed on one side of the support column 5. In order to cooperate with the stirring, a transmission structure is provided at one end of the support frame 6 and rotatably connected thereto. A stirring part 10 is provided at one end of the transmission structure and rotatably connected thereto. The curved part at the front end of the stirring part 10 extends into the interior of the stirring basin 1. When the stirring basin 1 rotates, the curved part at the front end of the stirring part 10 can stir.
[0015] like Figure 1 As shown: In order to achieve the rotation of the mixing bowl 1, a slot is provided at the top of the support column 5, and a bearing is installed inside the slot. The connecting rod 2 is inserted into the slot and interference-fitted with the bearing, thereby achieving the rotation of the mixing bowl 1 through the cooperation with the bearing.
[0016] like Figure 2 As shown: The drive structure consists of a worm gear 11 and a motor 12. The worm gear 11 is connected to the support column 5 through a mounting base. One end of the worm gear 11 is connected to the output end of the motor 12. The output end of the motor 12 drives the worm gear 11 to rotate. The worm gear 11 meshes with the worm wheel 3, thereby driving the mixing bowl 1 to rotate rapidly.
[0017] like Figure 1 , 3 As shown: The transmission structure includes a lower rod 7, two connecting rods 8, and an auxiliary rod 9. The lower rod 7 is hinged to the bottom corner of the support frame 6 to allow it to move. One end of each of the two connecting rods 8 is hinged to one end and two-thirds of the lower rod 7 to allow it to move, and the other end is hinged to the stirring part 10 to allow it to move. One end of the auxiliary rod 9 is hinged to the protruding part of the support frame 6, and the other end is hinged to the stirring part 10 to allow it to move.
[0018] Operating principle: Motor 12 drives worm gear 11 to rotate, and worm wheel 3, which cooperates with worm gear 11, drives mixing bowl 1 to rotate at high speed. Since the curved part of mixing part 10 extends into the interior of mixing bowl 1, the PVC raw materials and other materials inside can be fully mixed. When not in use, simply flip the stirring part 10 upwards to rotate it, and the curved part at the front end will disengage from the stirring bowl 1.
[0019] 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.
