Description

Technical Field

[0001] The utility model relates to the technical field of polymer foam beads processing, in particular to a polymer foam beads blanking device. Background Art

[0002] Polymer foam beads, such as thermoplastic polyurethane (TPU) foam beads (ETPU) and polypropylene foam beads, are widely used in packaging, transportation, shoe sole cushioning, and other fields due to their excellent properties such as low density and high resilience. However, during production, storage, and transportation, foam beads are prone to agglomeration due to factors such as ambient humidity, temperature fluctuations, and mechanical vibration. These agglomerates not only increase the difficulty of subsequent processing but also may affect the overall performance and use of the product.

[0003] During the production and packaging of polymer foam beads, ensuring uniformity and agglomeration of the beads is crucial for ensuring product quality. Existing polymer foam bead feeding devices struggle to separate agglomerated beads from a large number of beads, maintaining bead integrity and uniformity. Therefore, a polymer foam bead feeding device that can screen and separate agglomerated beads is needed. Utility Model Content

[0006] In a preferred embodiment of the present invention, the opening and closing assembly includes a guide sleeve, a guide rod and an electric push rod. The electric push rods are symmetrically provided on the left and right sides of the annular groove body, and the guide sleeves are symmetrically provided on the top positions of the left and right sides of the annular material frame. The guide rods are slidably sleeved in the guide sleeves, and the guide rods are fixedly connected to the outer wall of the annular sliding frame.

[0007] In a preferred embodiment of the present invention, it also includes a rotating shaft and a motor. The motor is installed in the middle of the cover, and a rotating shaft is rotatably set in the middle of the cover. The rotating shaft passes through the cover and is connected to the center of the top of the umbrella-shaped screen.

DETAILED DESCRIPTION

[0017] First of all, it should be noted that in the various embodiments described, identical components are provided with identical reference numerals or identical component names, wherein the disclosure contained throughout the entire description can be transferred to the same components having the same reference numerals or identical component names. Positional designations selected in the description, such as top, bottom, lateral, etc., also refer to the directly described and illustrated figures and are transferred to the new position in the event of a change in position.

[0018] Example: A polymer foam bead feeding device, such as Figures 1-4 As shown, it includes a support frame 1, a hopper 2, a support rod 3, an annular material frame 4, a cover 5, an opening and closing component 6, an annular sliding frame 63, a feeding pipe 7, an umbrella-shaped screen 8, an annular trough 9, a discharge pipe 10 and a solenoid valve 11. The hopper 2 is placed on the support frame 1, and two solenoid valves 11 are provided at intervals above and below the discharge end of the bottom of the hopper 2. An umbrella-shaped screen 8 is placed on the upper surface of the hopper 2. The umbrella-shaped screen 8 is high in the middle and low around, and circular sieve holes are evenly spaced apart. The foaming beads can be evenly spread around. An annular trough 9 is provided on the side wall of the hopper 2. A discharge pipe 10 is provided through the right side of the bottom of the annular trough 9. The bottom surface of the annular trough 9 is high on the left and low on the right, and the agglomerated foaming beads will gather in the annular trough. A discharge pipe 10 is provided on the right side of the trough body 9, and support rods 3 are symmetrically provided on the front and rear sides of the hopper 2. The other ends of the two support rods 3 are fixed on both sides of the annular material frame 4. The annular material frame 4 is located directly above the hopper 2 and is not in direct contact with the hopper 2. A lid 5 is provided on the top of the annular material frame 4, and a feed pipe 7 is provided on the lid 5. An annular slide frame 63 is slidingly provided on the outside of the annular material frame 4. The annular slide frame 63 is in close contact with the outer wall of the annular material frame 4 and the hopper 2. Both the hopper 2 and the annular slide frame 63 are made of transparent material, and the entire unloading process can be viewed. If there is a problem at any step, the unloading can be stopped at any time. An opening and closing component 6 that can drive the annular slide frame 63 to move up and down is symmetrically provided on the outside of the annular material frame 4.

[0019] like Figure 1-3 As shown, the opening and closing assembly 6 includes a guide sleeve 61, a guide rod 62 and an electric push rod 64. The electric push rods 64 are symmetrically provided on the left and right sides of the annular groove body 9, and the guide sleeves 61 are symmetrically provided on the top positions of the left and right sides of the annular material frame 4. The guide rod 62 is slidably sleeved in the guide sleeve 61. The guide rod 62 is fixedly connected to the outer side wall of the annular sliding frame 63, and the push rod of the electric push rod 64 is connected to the adjacent guide rod 62 through a mounting block.

[0020] like Figure 4 As shown, it also includes a rotating shaft 12 and a motor 13. The motor 13 is installed in the middle of the cover 5. The rotating shaft 12 is rotatably set in the middle of the cover 5. The rotating shaft 12 passes through the cover 5 and is connected to the top center of the umbrella-shaped screen 8. The motor 13 is installed on the top of the cover 5, and the output shaft of the motor 13 is connected to the top of the rotating shaft 12 through a coupling.

[0021] The staff installed the device just above the conveyor belt, and the foamed beads entered the annular material frame 4 along the feed pipe 7. The unclumped foamed beads were screened by the umbrella screen 8 and flowed into the bottom of the hopper 2. The staff controlled the motor 13 to work, and the motor 13 drove the rotating shaft 12 to rotate, thereby driving the umbrella screen 8 to rotate, accelerating the screening process of the umbrella screen 8, and thereby accelerating the unloading process. At this time, the lowest solenoid valve 11 is in a closed state, and the upper solenoid valve 11 is in an open state. As the position of the foamed beads accumulated at the bottom of the hopper 2 on the hopper 2 is higher than the position of the upper solenoid valve 11, the staff controlled the upper solenoid valve 11 to close and the lower solenoid valve 11 to open, and a certain amount of foamed beads flowed into the packaging box just below and were transported via the conveyor belt. The staff controlled the lower solenoid valve 11 to close and the upper solenoid valve 11 to open. When the foam beads accumulate to a position on the hopper 2 that is higher than the position of the upper solenoid valve 11, the same operation is performed again, and the cycle is repeated until the agglomerated foam beads screened out on the umbrella-shaped screen 8 fill the annular material frame 4, and the feed pipe 7 stops feeding. The staff controls the electric push rod 64 in the opening and closing component 6 to work, driving the guide rod 62 to move upward along the guide sleeve 61, thereby driving the annular slide frame 63 to move upward. Because the umbrella-shaped screen 8 is high in the middle and low around, and has many circular sieve holes, it is conducive to the agglomerated foam beads to flow from the middle of the umbrella-shaped screen 8 to the annular trough 9, and then flow out through the discharge pipe 10 for collection and subsequent processing. After the agglomerated foam beads flow out through the discharge pipe 10, the staff controls the electric push rod 64 in the opening and closing component 6 to drive the guide rod 62 and the annular slide frame 63 to reset, and the feed pipe 7 feeds again and enters the next cycle.

[0022] like Figure 1 As shown, a cross frame 14 is also included. The cross frame 14 is installed between the two parallel legs of the support frame 1. The cross frame 14 can reinforce the support frame 1 for the conveyor belt and also support the conveyor belt.
