Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigerator foam recovery devices, in particular to a refrigerator foam granulator. Background Art
[0002] During refrigerator disassembly and recycling, dismantlers remove the foam between the inner and outer walls. This foam is injected into the refrigerator's walls during manufacturing and hardens to form an effective insulating layer. This significantly reduces the amount of heat entering the refrigerator, maintaining a cooler internal environment and improving the refrigerator's energy efficiency and preserving food freshness. However, during refrigerator recycling, this foam is often bulky and difficult to compress and store. Utility Model Content
[0003] In view of the above problems in the prior art, the utility model provides a refrigerator foam granulator, which solves the problem that refrigerator foam is in a block shape and is inconvenient to compress and store.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0005] A refrigerator foam granulator is provided, comprising a recovery container for accommodating foam, wherein at least two extrusion wheels are arranged inside the recovery container for rotation by a rotating motor, the circumferential surfaces of two adjacent extrusion wheels are arranged tangentially, and a plurality of extrusion holes are provided on each circumferential surface, each extrusion wheel has an internal hollow structure and a discharge port shaft connected to the extrusion holes is provided on one end surface, and a cutting piece is provided at the discharge port of each discharge port shaft; the two adjacent extrusion wheels rotate to roll up the foam and extrude the foam into a plurality of strips through the plurality of extrusion holes, and the plurality of strips are cut into particles by the cutting piece on the discharge port shaft during the rotation of the extrusion wheels.
[0006] The working principle of this solution is that the motor is activated to drive each extrusion wheel to rotate, placing foam into a recovery container. The two extrusion wheels rotate, drawing the foam into the foam and forming it through multiple extrusion holes into multiple strips. The free ends of the multiple strips extend from the discharge port on the discharge shaft during the rotation and are cut into pellets by a cutting unit. By extruding the block foam into pellets, not only is the foam easier to compress and store, but the pellets are also more convenient for use as fuel.
[0007] Furthermore, the recycling container is an open-top box fixed to a support base. A discharge shaft on one end of each extrusion wheel and a drive shaft on the other end extend through both sides of the box and pivotally connect to a bearing block on the support base. The open top of the box facilitates the loading of large quantities of foam blocks into the recycling container, improving work efficiency. Furthermore, the bearing blocks secure the discharge shaft and drive shaft, ensuring stable and safe operation, reducing wear and extending the service life of the equipment.
[0008] Furthermore, each drive shaft is connected to a rotating motor fixed to the support base. The number of rotating motors is adjusted to the number of drive shafts, allowing each extrusion wheel to independently and precisely control its rotational speed, improving the overall efficiency of the pelletizer and the quality of the foam pellets. Independent transmission also reduces the impact of single points of failure, improving equipment reliability.
[0009] Furthermore, two adjacent drive shafts are connected by a belt drive, chain drive, or gear drive, and one of the drive shafts is connected to a rotary motor fixed to the support base. Providing only one rotary motor reduces costs and can synchronize the rotation of the two adjacent extrusion wheels, ensuring that the foam can be evenly and continuously rolled in and extruded.
[0010] Furthermore, the rotating motor is provided with a speed reducer, which increases the output torque of the rotating motor.
[0011] Furthermore, each discharge port shaft is an shaft structure that is hollow inside and open at both ends, and the diameter of the discharge port shaft is larger than the diameter of the transmission shaft. Setting the diameter of the discharge port shaft in this way ensures sufficient internal separation space, prevents the foam material from interfering with the transmission shaft, and increases the stability and safety of the equipment.
[0012] Furthermore, each cutting member is a cutting knife fixed on a bearing seat rotatably connected to the discharge port shaft. The cutting knife is fixed on the bearing seat and cuts the rotating strip into particles.
[0013] Furthermore, the multiple extrusion holes on each extrusion wheel are evenly distributed.
[0014] Furthermore, the plurality of extrusion holes on each extrusion wheel are arranged in a rectangular array.
[0015] Furthermore, extrusion strips distributed in the radial direction are arranged between two adjacent rows of extrusion holes on each extrusion wheel, and multiple extrusion strips on two adjacent extrusion wheels are meshed. The arrangement of the extrusion strips can better press the foam into the extrusion holes.
[0016] The utility model discloses a refrigerator foam granulator, which has the following beneficial effects:
[0017] The utility model first squeezes the block foam into strips by means of a rotating extrusion wheel, and then cuts the free ends of the multiple strips into particles by means of a cutting piece in a rotating state, thereby realizing the function of converting the block foam into particles, reducing the gaps between the foams, not only facilitating compression and storage, but also making the granular foam convenient to use as fuel.

The plurality of extrusion strips 21 on two adjacent extrusion wheels 2 are meshed. The arrangement of the extrusion strips 21 can better press the foam into the extrusion holes.
[0028] Specifically, refer to Figure 4Each cutting piece 7 is a cutting knife fixed on a bearing seat 5 rotatably connected to the discharge port shaft 3. The cutting knife is fixed on the bearing seat 5 to cut the rotating strip into particles.
[0029] Specifically, as the rotating structure of the recycling container 1 and the extrusion wheels 2, a discharge shaft 3 on one end of each extrusion wheel 2 and a drive shaft 4 on the other end respectively pass through both sides of the box body and are rotatably connected to a bearing seat 5 located on the support base. Each discharge shaft 3 is a hollow shaft structure with open ends, and the diameter of the discharge shaft 3 is larger than the diameter of the drive shaft 4.
[0030] A reducer is provided on the rotating motor 6.
