Description

[0001] The utility model relates to the field of plastic foam processing, in particular to a plastic foam particle conveying device. Background Art

[0002] With the continuous development of industrial production technology, the production cost of plastic foam products is getting lower and lower. In the production process of plastic foam products, the foamed foam particles need to be transported to the foam mold, and then the foam mold is thermoformed into corresponding foam plastic blocks.

[0003] The current plastic foam particle conveying device, as described in the patent with announcement number CN212888462U, includes a support frame and a movable rod, a conveying pipe is fixed to the upper end of the support frame, and a first motor is installed on the left side of the conveying pipe, and a pushing rod is arranged on the outer side of the first motor, a discharge pipe is fixed to the right side of the conveying pipe, and a linkage rod is installed on the upper part of the discharge pipe, and fan blades are fixed on the outer side of the linkage rod, a fixed frame is fixed to the upper end of the conveying pipe, and a second motor is installed on the left side of the lower part of the fixed frame, and a vertical rod is installed on the upper end of the second motor, a cross rod is connected to the right side of the lower part of the vertical rod, an extrusion block is fixed to the outer side of the cross rod, and a movable gear ring is connected to the right side of the upper part of the vertical rod.

[0004] With regard to the above-mentioned related technologies, the inventor believes that although the linkage rod drives the fan blades to inject wind into the inside of the discharge pipe, which can achieve sufficient falling of the material inside the discharge pipe, the foam particles are relatively light, so after being transported to the foam mold, the foam will be blown out of the foam mold due to the airflow formed by the rotation of the fan blades, causing the foam particles to scatter, thereby increasing the cleaning work of the staff.

DETAILED DESCRIPTION

[0024] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0025] See also Figure 1-4 The plastic foam particle conveying device comprises a flow guiding mechanism 1, the flow guiding mechanism 1 comprises a flow guiding pipe 101, and a support rod 102 is symmetrically fixedly connected to the lower side of the outer wall of the flow guiding pipe 101, and the setting of the support rod 102 can support the flow guiding pipe 101. A hopper 103 is rotatably connected to one side of the top of the flow guiding pipe 101, and the setting of the hopper 103 is used to accommodate the foam particles to be conveyed. A discharge pipe 104 is fixedly connected to one side of the bottom of the flow guiding pipe 101, and the setting of the discharge pipe 104 can discharge the foam particles inside the flow guiding pipe 101. The blowing mechanism 2 comprises a cover plate 201 rotatably connected to one side of the top of the discharge pipe 104, and the setting of the cover plate 201 is used to cover the top of the hopper 103.

[0026] The outer wall of the hopper 103 is symmetrically rotatably connected with the first hydraulic rod 202, and the output ends of the two groups of first hydraulic rods 202 are both rotatably connected with the cover plate 201. The first hydraulic rod 202 can pull the cover plate 201 to rotate when starting work, so as to realize the opening or closing of the hopper 103. The top of the cover plate 201 is fixedly connected with a blower 204, and the output end of the blower 204 is fixedly connected with a connected air duct 205, which passes through the cover plate 201 and is connected with the cover plate 201. The airflow generated by the blower 204 when starting work can be blown to the inside of the hopper 103 through the air duct 205, so as to blow the foam particles inside the hopper 103, so that the foam particles are blown to the inside of the discharge pipe 104 through the air duct 101. A first filter 206 is provided at the bottom of the cover 201, and the first filter 206 is fixedly connected to one end of the air duct 205 close to the hopper 103. The setting of the first filter 206 can block the foam particles inside the hopper 103 to reduce the probability of the foam particles inside the hopper 103 being discharged into the blower 204 through the air duct 205.

[0027] The bottom of the cover plate 201 is fixedly connected with a sealing gasket 203, and the sealing gasket 203 abuts against the top wall of the hopper 103. The setting of the sealing gasket 203 can seal the gap between the cover plate 201 and the hopper 103 when the cover plate 201 is closed, so as to reduce the probability of airflow flowing out through the gap between the cover plate 201 and the hopper 103. The injection mechanism 3 includes an annular plate 301 fixedly connected to the bottom of the discharge pipe 104, and the top of the annular plate 301 is fixedly connected with a reinforcing rib plate 302 in an annular array. Each group of reinforcing rib plates 302 is fixedly connected to the discharge pipe 104. The setting of the reinforcing rib plates 302 can further connect and fix the annular plate 301 and the discharge pipe 104, thereby improving the connection stability between the annular plate 301 and the discharge pipe 104.

[0028] The bottom of the annular plate 301 is fixedly connected with a connected rubber bellows 304, and the setting of the rubber bellows 304 can guide the foam particles and airflow discharged from the discharge pipe 104. The bottom of the rubber bellows 304 is fixedly connected with an annular bottom plate 303, and the inside of the annular plate 301 is symmetrically penetrated and fixed with a second hydraulic rod 305, and the output ends of the two groups of second hydraulic rods 305 are fixedly connected with the annular bottom plate 303. The second hydraulic rod 305 is used to drive the annular bottom plate 303 to move up and down when starting the work, so as to adjust the height of the annular bottom plate 303. The top of the annular bottom plate 303 is fixedly connected with a plurality of extension blocks 306 in an annular array, and the bottom of each group of extension blocks 306 is detachably connected with a cover plate 310, and the setting of the cover plate 310 can cover the foam inlet of the foam mold, so that the foam particles are discharged into the foam mold through the rubber bellows 304 and the annular bottom plate 303.

[0029] The interior of each group of extension blocks 306 is threadedly connected with fixing bolts 307, and each group of fixing bolts 307 is threadedly connected to the cover plate 310. The use of fixing bolts 307 to connect and fix the extension blocks 306 to the cover plate 310 can facilitate the subsequent replacement of cover plates 310 of different specifications, thereby adapting to foam molds of different specifications. The interior of the annular bottom plate 303 is provided with a plurality of exhaust ports 308 in an annular array, and the setting of the exhaust ports 308 facilitates the discharge of the airflow discharged into the interior of the foam mold. The interior of each group of exhaust ports 308 is provided with a second filter screen 309 fixedly connected to the annular bottom plate 303, and the setting of the second filter screen 309 can filter the airflow passing through the interior of the exhaust port 308 to reduce the probability of foam particles being discharged from the interior of the foam mold with the airflow.

[0030] In this embodiment, the blower 204 is a prior art and will not be described in detail here.

[0031] When in use, unscrew each group of fixing bolts 307, then take out the foam particles of the foam mold and put them into the corresponding covering plate 310, and then screw the corresponding covering plate 310 and each group of extension blocks 306 and fixing bolts 307, and then start the first hydraulic rods 202 on both sides to make the first hydraulic rods 202 on both sides extend, thereby pulling the cover plate 201 to rotate, so that the top of the hopper 103 is opened, and the plastic foam is poured into the hopper 103, and then start the first hydraulic rods 202 on both sides again to make the first hydraulic rods 202 on both sides contract, thereby driving the cover plate 201 to rotate until the cover plate 201 covers the top of the hopper 103, and then start the second hydraulic rod 305 to make the second hydraulic rod 305 extend, thereby driving the annular bottom plate 303 and the covering plate 310 to move downward until the covering plate 310 opens the foam. The foam particles of the foam mold are placed into the inlet and covered, and then the blower 204 can be started. The airflow generated by the blower 204 when starting can be discharged into the interior of the hopper 103, so that the foam particles in the hopper 103 are blown into the interior of the rubber bellows 304 through the guide pipe 101 and the discharge pipe 104, and then discharged into the interior of the foam mold through the rubber bellows 304, and the airflow is discharged through the exhaust port 308. Due to the filtering of the second filter screen 309, the foam can be prevented from continuing to be discharged from the mold with the airflow. After the mold is filled with foam particles, the blower 204 is turned off, and the second hydraulic rod 305 is started again to make the second hydraulic rod 305 contract, thereby driving the annular bottom plate 303 and the covering plate 310 to move upward, so that the covering plate 310 is separated from the foam particle inlet of the foam mold, thereby completing the transportation and addition of the foam particles.

They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
