Description
Technical Field
The utility model relates to a cable production device, in particular to a PVC particle weighing device.
Background
After the PVC particles are produced, the PVC particles need to be packed according to the specified weight. The existing packaging method comprises the following steps: PVC particles are fed into the hopper, weighed by a metering device arranged on the hopper, and released when the set weight is reached, and fall into a packaging bag below. In actual production, since the packing weight is large (at least one ton) at a time and PVC particles fall only by gravity, the packing speed is slow, it takes more than 20 minutes, and the working efficiency is low.
Disclosure of Invention
The utility model aims to overcome the defects in the background technology and provide the PVC particle weighing device which has the characteristics of low modification cost and high discharging speed.
The technical scheme of the utility model is as follows:
the PVC particle weighing device comprises a weighing hopper which is arranged on a bracket and is provided with a weight sensor, and a pneumatic conveying mechanism for conveying PVC particles to weighing; the method is characterized in that: the device also comprises a controller and a booster fan; the weighing hopper is provided with a pressurizing port, and the pressurizing fan is communicated with the pressurizing port through a pressurizing pipe; the feed inlet of weighing hopper is equipped with the feed valve, and the pressurization mouth of weighing hopper is equipped with the pressurization valve, and the discharge gate of weighing hopper is equipped with the discharge valve.
The weighing hopper is internally provided with a stirring paddle, and the top of the weighing hopper is provided with a motor for driving the stirring paddle to rotate
The controller is electrically connected with the pneumatic conveying mechanism, the weight sensor, the feeding valve, the discharging valve, the pressurizing fan and the motor.
The beneficial effects of the utility model are as follows:
the utility model is used for modifying the existing hopper, the discharging speed of PVC particles is increased by pressurizing the inside of the weighing hopper during discharging, and the PVC particles are kept in a moving state by using the rotating stirring paddles, so that the discharging speed is further increased, the modifying cost is low, the discharging speed is high, at least half of packing time can be saved, and the working efficiency is effectively improved.

Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
As shown in figure 1, the PVC particle weighing device comprises a weighing hopper 1, a pneumatic conveying mechanism 2, a pressurizing fan 3, a stirring paddle 5, a motor 6 and a controller.
The weighing hopper is fixed on a bracket 9, and a weight sensor (omitted in the figure) is arranged on the bracket and used for weighing the weighing hopper, and the weighing hopper and the ground keep a certain height for discharging and packaging.
The weighing hopper, the weight sensor, the bracket and the pneumatic conveying mechanism are all in the prior art.
The upper part of the weighing hopper is provided with a feed inlet 1.1 and a pressurizing inlet 1.2, the bottom of the weighing hopper is provided with a discharge outlet 1.3, the feed inlet is provided with a feed valve (omitted in the figure), the pressurizing inlet is provided with a pressurizing valve (omitted in the figure), and the discharge outlet is provided with a discharge valve (omitted in the figure). The pneumatic conveying mechanism is communicated with the feeding port. The pressurizing fan is communicated with the pressurizing port through a pressurizing pipe 4.
The stirring paddle is rotatably positioned in the weighing hopper, and the motor is arranged at the top of the weighing hopper and used for driving the stirring paddle to rotate.
The controller is electrically connected with the feed valve, the discharge valve, the pressurization fan and the motor. The feeding valve, the discharging valve, the pressurizing fan and the motor are all in the prior art.
The working principle of the utility model is as follows:
1. feeding: the feeding valve is opened, the pressurizing valve and the discharging valve are closed, the pneumatic conveying mechanism sends PVC particles into the weighing hopper, and when the PVC particles reach the preset weight, the pneumatic conveying mechanism stops, and the feeding valve is closed;
2. discharging: the packaging bag is placed below the discharge hole, the pressurizing valve and the discharge valve are opened, the pressurizing fan is started to pressurize the inside of the weighing hopper, the dropping speed of PVC particles is accelerated, and meanwhile, the motor is started to drive the stirring paddle to slowly rotate, so that the PVC particles keep a moving state, and the phenomenon that the PVC particles are accumulated to influence the discharge is avoided; after the discharging is finished, the pressurizing valve and the discharging valve are closed, and the pressurizing fan and the motor are stopped; the PVC particles of one ton can be discharged in 10 minutes, so that the discharging speed is greatly improved.
Preferred embodiments of the present utility model are shown in the drawings. This utility model may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
