Description

Technical Field

[0001] The utility model relates to the technical field of insulating cable sheath raw material processing, in particular to a mixing device for insulating cable sheath raw material processing. Background Art

[0002] The outside of the cable is often coated with insulating material, which can effectively reduce the situation of cable connection and reduce the situation after cable wear, thereby improving the protection effect of the cable. When producing cable insulation materials, it is often necessary to mix the cable raw materials so that the different components are mixed evenly before production, and stir them evenly through a stirring device. However, the existing stirring device uses a multi-axis stirring method to pass the raw materials into the cylinder, and the stirring efficiency is low. When transmitting the raw materials, a single channel is used for transmission, and the transmission efficiency is low.

[0003] For example, Chinese patent publication No. CN217909976U discloses a raw material mixing device for the production of cable insulation materials. When in use, the raw materials are introduced into the interior of the mixing box through a feed pipe and through the semi-spherical shell shape of the mixing box, which is conducive to guiding the raw materials and replacing the shape of the edges to reduce the difficulty in cleaning at the turning points. The transmission shaft, the stirring half ring and the stirring shaft are driven by the motor to rotate, thereby stirring the raw materials inside the mixing box. During the stirring process, the gas is introduced into the interior of the mixing box through the air duct, thereby improving the stirring effect. After the stirring is completed, the valve is opened and the raw materials are guided to the belt transmission device through the guide plate. The belt transmission device drives the raw materials to different areas to improve the transmission efficiency.

[0004] However, the raw material mixing device used for the production of cable insulation materials in the above application still has a relatively low stirring efficiency, and the cable insulation material will adhere to the inner wall of the mixing box during the stirring process, and needs to be cleaned to avoid affecting subsequent use. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a mixing device for processing the raw materials of insulating cable sheath. Utility Model Content

[0006] The purpose of the utility model is to provide a mixing device for processing raw materials for insulating cable sheaths, so as to solve the problem that the raw material mixing device for cable insulation material production proposed in the above-mentioned background technology is still relatively low in stirring efficiency, and the cable insulation material will adhere to the inner wall of the mixing box during the stirring process, and it needs to be cleaned to avoid affecting subsequent use.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a mixing device for processing raw materials for insulating cable sheaths, comprising a mixing box and supporting legs, wherein the four supporting legs are respectively fixedly connected to the four corners of the lower surface of the mixing box, and a mixing mechanism and a cleaning mechanism are provided inside the mixing box.

[0008] The mixing mechanism comprises a mixing unit and a stirring unit. The mixing unit is installed inside the mixing box, and the stirring unit is installed on the mixing unit.

[0009] The mixing unit includes a driving motor, a transmission part, a rotating shaft, a stirring rod, and a turning auger. The driving motor is installed on the top left side of the mixing box, the transmission part is connected to the output end of the driving motor, the rotating shaft is rotatably connected to the inside of the transmission part, and its bottom extends into the inside of the mixing box, the two groups of stirring rods are fixedly connected to the upper and lower sides of the outer surface of the rotating shaft respectively, and the turning auger is fixedly connected to the middle of the rotating shaft. Starting the driving motor drives the rotating shaft in the transmission part to rotate, thereby driving the main bevel gear outside the rotating shaft to rotate, and then driving the secondary bevel gear meshed with it to rotate, thereby driving the rotating shaft to rotate, and the stirring rod installed on the outer surface of the rotating shaft is used to stir and mix the raw materials inside the mixing box, wherein the turning auger turns the bottom raw materials to the top when the rotating shaft rotates, thereby avoiding the sedimentation of the raw materials and causing uneven mixing.

[0010] A further improvement is that the stirring unit includes a sliding sleeve, a stirring device, and a magnetic ring. The sliding sleeve is sleeved on the stirring rod. The six stirring devices are fixedly connected to the outer surface of the sliding sleeve in a ring shape. The magnetic ring is fixedly connected to the outer side of the outer surface of the stirring rod.

[0011] A further improvement is that the sleeve is made of magnetic material, and a cutting hole is opened through the outer surface of the stirrer. When the stirring rod stirs the raw materials, the centrifugal force it generates pushes the sleeve to slide outward, and in this process drives the stirrer to rotate and hit the raw material liquid, and cooperates with the cutting holes on its outer surface to cut and disturb the raw material liquid, thereby further improving the mixing effect. The setting of the magnetic ring prevents the sleeve from moving outward excessively, driving the stirrer to hit the inner wall of the mixing box and causing damage.

[0012] A further improvement is that the cleaning mechanism includes a water injection pipe, a connecting pipe, a high-pressure nozzle, and a side wall scraper. The front end of the water injection pipe is installed on the top of the rotating shaft, the two connecting pipes are respectively fixedly connected to the top of the outer surface of the rotating shaft, the two groups of high-pressure nozzles are equidistantly fixedly connected to the bottom of the connecting pipe, and the side wall scraper is fixedly connected to the outer end of the stirring rod and fits into the inner wall of the mixing box.

[0013] A further improvement is that a water delivery cavity is opened inside the rotating shaft, the front end of the water injection pipe is installed on the top of the water delivery cavity through a bearing, and the inner end of the connecting pipe extends into the interior of the water delivery cavity. After the mixing is completed, the water injection pipe is installed inside the bearing of the water delivery cavity at the top of the rotating shaft, so that the external water source is input into the water delivery cavity through the water injection pipe, and then flows into the interior of the connecting pipe and is sprayed out through the high-pressure nozzle. The rotation of the rotating shaft drives the side wall scraper to rotate to rinse and clean the inner wall of the mixing box and the entire surface of the mixing mechanism.

[0014] A further improvement is that a filling pipe is fixedly connected to the top right side of the mixing box, and a discharge pipe is fixedly connected to the bottom center of the mixing box. An electric sealing valve is installed on the outer surface of the discharge pipe. The raw materials are poured into the interior of the mixing box through the filling pipe. After the mixing is completed, the electric sealing valve is opened and the material inside the mixing box is discharged through the discharge pipe.

[0015] A further improvement is that an observation window is installed on the front of the mixing box, a controller is installed above the front of the mixing box, the mixing mechanism is electrically connected to the controller, the mixing of raw materials inside the mixing box can be observed in real time through the observation window, and the normal operation of the device is controlled by the controller.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The mixing device for processing raw materials for insulating cable sheaths drives the rotating shaft to rotate through a driving motor, and then drives the stirring rod to stir and mix the raw materials inside the mixing box. The turning auger turns the raw materials at the bottom to the top when the rotating shaft rotates, thereby avoiding the sedimentation of the raw materials and causing uneven mixing.

[0018] 2. In the mixing device for processing raw materials for insulating cable sheaths, when the stirring rod stirs the raw materials, the centrifugal force it generates pushes the sleeve to slide outward, and in this process drives the stirring rod to rotate and hit the raw material liquid, and cooperates with the cutting holes on its outer surface to cut and disturb the raw material liquid, thereby further improving the mixing effect. The setting of the magnetic ring prevents the sleeve from moving outward excessively, driving the stirring rod to hit the inner wall of the mixing box and causing damage.

[0019] 3. The mixing device for processing raw materials for insulating cable sheaths inputs external water into the water delivery cavity through the water injection pipe, and then flows into the interior of the connecting pipe and is sprayed out through the high-pressure nozzle. The rotation of the rotating shaft drives the side wall scraper to rotate to rinse and clean the inner wall of the mixing box and the entire surface of the mixing mechanism.
