Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning ventilation pipe production technology, specifically to automotive air conditioning ventilation pipe raw material mixing equipment. Background Technology

[0002] Currently, automotive air conditioning ventilation ducts are mostly processed using blow molding or injection molding, and the mixing quality of various raw materials directly affects the processing quality of automotive air conditioning ventilation ducts.

[0003] For example, the utility model disclosed in authorization announcement number CN218339708U discloses a material mixing and feeding device for scrap materials in the production of automotive ventilation pipes. It solves the problems of easy blockage at the feed inlet and inconvenience in mixing and reusing many scrap materials. However, it has the problems of inconvenience in fully agitating the raw materials, poor mixing effect of raw materials, and low feeding efficiency.

[0004] Therefore, we propose a mixing equipment for automotive air conditioning ventilation duct materials. Utility Model Content

[0005] The purpose of this invention is to address the problems of existing automotive air conditioning ventilation duct raw material mixing equipment, such as inconvenience in fully agitating raw materials, poor mixing effect, and low feeding efficiency, and to provide an automotive air conditioning ventilation duct raw material mixing equipment with a reasonable structural design, which can fully agitate raw materials, achieve good mixing effect, and have high feeding efficiency.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0007] An automotive air conditioning ventilation duct raw material mixing device includes a base and a mixing chamber. A transmission structure is installed on the base. The bottom of the mixing chamber is movably mounted on the base. A feeding structure is installed at the top of the mixing chamber, and a discharge pipe is installed at the bottom. A drive structure is installed on the outer wall of the mixing chamber. Inside the mixing chamber, a double-screw, a first rotating shaft, and a second rotating shaft are arranged sequentially from top to bottom, and all three are movably connected to the drive structure. Various raw materials for automotive air conditioning ventilation ducts to be mixed are added to the mixing chamber through the feeding structure. The drive structure drives the double-screw, the first rotating shaft, and the second rotating shaft to rotate, which fully agitates the raw materials in the mixing chamber, improving the mixing efficiency and quality, and thus improving the processing quality of the automotive air conditioning ventilation ducts.

[0008] Preferably, the base is provided with a bottom groove, and the bottom of the mixing box is provided with a fixing post. The fixing post is inserted into the bottom groove, and a spring is sleeved on the fixing post between the base and the bottom of the mixing box. Inserting the fixing post at the bottom of the mixing box into the bottom groove allows the mixing box to move vertically on the base, causing the automotive air conditioning ventilation pipe raw material in the mixing box to shake, thus fully mixing the automotive air conditioning ventilation pipe raw material.

[0009] Preferably, the transmission structure includes a rotary motor and a pusher block. The rotary motor is mounted on a base and has a drive shaft. The pusher block is mounted on the drive shaft and is elliptical in shape. The pusher block is designed to periodically push the bottom of the mixing chamber. The rotary motor drives the drive shaft and the pusher block on the drive shaft to rotate. The elliptical pusher block periodically pushes the mixing chamber upward. The two rotary motors work together to make the mixing chamber horizontal or inclined on the base, which facilitates the back-and-forth rolling of the automotive air conditioning ventilation pipe material in the mixing chamber, thereby improving the mixing efficiency and mixing effect of the automotive air conditioning ventilation pipe material.

[0010] Preferably, the bottom of the mixing chamber is designed with an arc shape, and a sealing cap is movably installed on the discharge pipe at the bottom of the mixing chamber. The arc shape of the bottom of the mixing chamber facilitates the flow of the mixed automotive air conditioning ventilation pipe raw material into the discharge pipe. The discharge pipe and the sealing cap are connected by threads, which facilitates the installation and removal of the sealing cap. During the mixing process of the automotive air conditioning ventilation pipe raw material, the sealing cap closes the discharge pipe to prevent the raw material from flowing out of the discharge pipe during the mixing process. After the automotive air conditioning ventilation pipe raw material is mixed, the sealing cap is removed, and the mixed automotive air conditioning ventilation pipe raw material is quickly discharged from the discharge pipe, thereby improving the discharge efficiency of the mixed raw material.

[0011] Preferably, the drive structure includes a drive motor, which is configured as a servo motor. A fixed plate is provided on the outer wall of the mixing chamber, and the drive motor is mounted on the fixed plate. A drive shaft is provided on the drive motor, and a bevel gear is provided on the drive shaft, which is movably connected to a double-screw screw, a rotating shaft one, and a rotating shaft two, respectively. The drive motor drives the drive shaft and the bevel gear one on the drive shaft to rotate, and the bevel gear one drives the double-screw screw, the rotating shaft one, and the rotating shaft two to rotate, thereby fully agitating the raw materials of the automotive air conditioning ventilation pipe in the mixing chamber and effectively improving the mixing efficiency and mixing quality of the raw materials of the automotive air conditioning ventilation pipe.

[0012] Preferably, the inner wall of the mixing chamber is equipped with bearings. One end of the twin-screw, rotating shaft one, and rotating shaft two are inserted into the bearings, and the other end protrudes from the bearings. A bevel gear two, meshing with a bevel gear one, is provided at one end of each of the twin-screw, rotating shaft one, and rotating shaft two. A stirring rod is provided on rotating shaft one, and two opposing spiral stirring plates are provided on rotating shaft two. A drive motor drives the drive shaft and bevel gear one on the drive shaft to rotate. Bevel gear one, through bevel gear two, drives the twin-screw, rotating shaft one, and rotating shaft two to rotate respectively. Rotating shaft one drives the stirring rod to rotate, thus agitating the automotive air conditioning ventilation duct material in the mixing chamber. Rotating shaft two drives the spiral stirring plates, which can tumble the automotive air conditioning ventilation duct material up and down, thoroughly mixing it and improving the mixing efficiency and quality.

[0013] Preferably, a connecting sleeve is fitted onto the twin-screw, a movable plate is provided on the connecting sleeve, and a toggle rod is provided on the movable plate. The twin-screw rotates under the action of the drive motor, and the twin-screw pushes the connecting sleeve to move back and forth. The connecting sleeve drives the movable plate to move back and forth in the mixing box, so that the toggle rod on the movable plate moves back and forth to move the automotive air conditioning ventilation pipe raw material, thereby fully mixing the automotive air conditioning ventilation pipe raw material.

[0014] Preferably, the mixing box is provided with a horizontal limiting rod, and the moving plate is provided with a limiting ring. The limiting rod is inserted into the limiting ring. During the process of the moving plate moving back and forth driven by the connecting sleeve, the limiting ring moves back and forth on the limiting rod, so that the limiting rod and the limiting ring limit the moving plate moving back and forth, thereby improving the stability of the process of the actuating rod actuating the raw materials of the automotive air conditioning ventilation pipe.

[0015] Preferably, the feeding structure includes a feeding box, which is set on the mixing box. An arc-shaped guide plate is installed inside the mixing box. A feeding hopper is located at the top of the feeding box, and a sealing cover is movably installed on the top of the feeding hopper. Various raw materials for the automotive air conditioning ventilation ducts to be mixed are poured into the feeding box through the feeding hopper. The raw materials fall onto the arc-shaped guide plate, which fully disperses the materials, facilitating thorough mixing. The feeding hopper and the sealing cover are connected by threads, allowing for easy installation or removal of the sealing cover from the feeding hopper. During the mixing process of the automotive air conditioning ventilation duct raw materials, the sealing cover covers the feeding hopper, preventing the raw materials from splashing out of the feeding hopper and reducing material waste.

[0016] Beneficial effects:

[0017] 1. A rotary motor drives the drive shaft and the pusher block on the drive shaft to rotate. The elliptical pusher block periodically pushes the mixing box upward. The two rotary motors work together to make the mixing box horizontal or inclined on the base, which facilitates the back and forth rolling of the automotive air conditioning ventilation pipe raw material in the mixing box, thereby improving the mixing efficiency and mixing effect of the automotive air conditioning ventilation pipe raw material.

[0018] 2. Rotating shaft one drives the stirring rod to rotate, which stirs the raw materials of the automotive air conditioning ventilation pipe in the mixing box. Rotating shaft two drives the spiral stirring plate, which can turn the raw materials of the automotive air conditioning ventilation pipe up and down, so as to fully mix the raw materials of the automotive air conditioning ventilation pipe and improve the mixing efficiency and mixing quality of the raw materials of the automotive air conditioning ventilation pipe.

[0019] 3. The various raw materials for the automotive air conditioning ventilation duct that need to be mixed are poured into the feeding box through the feeding hopper. The raw materials fall onto the arc-shaped guide plate, which can fully disperse the raw materials, making it easier to fully mix the raw materials and improve the mixing efficiency and mixing effect of the automotive air conditioning ventilation duct raw materials.
