Description

Technical Field

[0002] The main components of the plastic extruder include an extruder, a molding device and a plastic particle feeding device. The extruder is composed of an extrusion system, a transmission system and a heating and cooling system. The plastic particle feeding device mainly provides plastic particle raw materials for the extruder. For example, the patent with announcement number CN214324114U discloses a plastic particle feeding device for an extruder, including a storage box, a screw shaft, a driven wheel and a meter. A screw shaft is installed on the storage box, and a transmission belt is connected to the screw shaft. A feed port is arranged below the transmission belt, and a dust removal channel is connected below the feed port. A filter is installed on the dust removal channel, a stirring blade is arranged on the right side of the filter, and a fan blade is arranged on the right side of the stirring blade. The fan blade is installed on the first motor, and the first motor is fixed on the bracket. The device is provided with a rotatable metering device. When the plastic particles reach the set amount, the first flip plate and the second flip plate will flip upward and close, timely preventing the continued feeding of the plastic particles, thereby improving the accuracy of quantitative feeding. However, when the particles fall, they will have a certain impact on the meter, causing the result measured by the meter to be larger, thus causing errors in quantitative feeding, and when a large amount of feeding is performed, it is not convenient to handle the excess particles.

[0003] To this end, the utility model provides a quantitative feeding device for an XPS extruded board. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a quantitative feeding device for XPS extruded board, comprising a storage box 1, a distribution box 8 is fixed at the lower side of the storage box 1, a storage cavity 2 and a quantitative cavity 3 are provided in the storage box 1, the storage cavity 2 is communicated with the quantitative cavity 3, a first discharge port 4 is provided at the bottom of the storage box 1, the first discharge port 4 is communicated with the distribution box 8, a first partition 21 is slidably fitted in the first discharge port 4, a weighing device 22 is fixed in the first partition 21, a pressure rod 16 is installed at the lower side of the first partition 21, a material guide plate 14 is rotatably fitted in the distribution box 8, and a discharge port 10 and a recovery port 12 are provided at the bottom of the distribution box 8.

[0022] In this embodiment, a second partition 5 is fixed in the material storage box 1. The second partition 5 is a funnel-shaped structure. The second partition 5 is located between the material storage chamber 2 and the quantitative chamber 3. A second discharge port 7 is opened in the second partition 5. The second discharge port 7 is connected with the material storage chamber 2 and the quantitative chamber 3. A solenoid valve 6 is fixed in the second discharge port 7.

[0023] Specifically, the extruded particles can be poured into the storage chamber 2 of the storage box 1. When feeding is needed, the solenoid valve 6 is started to allow the extruded particles to flow into the quantitative chamber 3 through the second discharge port 7. The amount of extruded particles flowing into the quantitative chamber 3 can be controlled by controlling the opening time of the solenoid valve 6. The extruded particles entering the quantitative chamber 3 can be weighed by the weighing device 22 to ensure accurate quantification.

[0024] A groove 18 and a receiving groove 19 are provided at the bottom of the material storage box 1. The groove 18 and the receiving groove 19 are both connected to the first material discharge port 4. The receiving groove 19 corresponds to the first partition 21. An electric cylinder 20 is fixed in the groove 18, and the output end of the electric cylinder 20 is fixedly connected to the first partition 21.

[0025] Specifically, the extruded particles weighed by the weighing device 22 remain in the quantitative chamber 3. When feeding, the electric cylinder 20 is started, and the electric cylinder 20 drives the first partition 21 to move, so that the first partition 21 enters the storage groove 19, thereby facilitating the extruded particles to flow from the first discharge port 4 into the distribution box 8, and feeding can be carried out.

[0026] The first partition 21 is rotatably connected to the pressure rod 16, one end of the pressure rod 16 is located in the distribution box 8, a spring 17 is fixed between the pressure rod 16 and the inner wall of the distribution box 8, a rotating shaft 13 is installed between the box wall of the distribution box 8 and the material guide plate 14, the rotating shaft 13 is rotatably connected to the distribution box 8, the rotating shaft 13 is fixedly connected to the material guide plate 14, and a counterweight block 15 is fixed to the bottom of the material guide plate 14 away from the pressure rod 16.

[0027] Specifically, when weighing is required, if there are many extruded particles at this time, the electric cylinder 20 can be started, so that the electric cylinder 20 drives the first partition 21 to move slowly, and a certain gap is generated between the first partition 21 and the first discharge port 4, so that the excess extruded particles are pushed into the distribution box 8, and flow out from the recovery port 12 through the guide plate 14, and the extruded particles can be recovered. At this time, since the gap between the first partition 21 and the first discharge port 4 is small, the first partition 21 drives the pressure rod 16 to move a small distance, and the pressure rod 16 does not contact the guide plate 14 until the excess extruded particles are pushed out, and then the electric cylinder 20 drives the first partition 21 to quickly reset, and the first discharge port 4 can be blocked.

[0028] When feeding, start the electric cylinder 20, so that the electric cylinder 20 drives the first partition 21 to move quickly, so that the first discharge port 4 is fully opened. At this time, the first partition 21 drives the pressure rod 16 to move, so that the pressure rod 16 rotates, so that the pressure rod 16 presses the guide plate 14 downward, and the guide plate 14 rotates to guide the extruded particles to the discharge port 10, so as to feed.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
