Technical Field

[0001] The utility model relates to the technical field of material compressors, in particular to a granulation auxiliary material compression device. Background Art

[0002] A pellet compressor is a device that compresses powdered, granular, or flake materials into pellets under high pressure. This equipment is widely used in industries such as plastics, chemicals, feed, fertilizer, and biomass, primarily to convert raw materials into pellets that are easy to store, transport, and use.

[0003] After the waste is crushed by the crusher, it is sent to the pellet compressor by the conveying structure and compressed into granules, which are then used as auxiliary materials for the production of plastic pellets. However, in this process, if the particle size of the crushed material is uneven, the overly large particles will have difficulty passing through the die hole of the compressor smoothly, causing blockage; in addition, too much fine powder may also aggregate into clumps due to static electricity, affecting the normal production process and causing blockage inside the compressor. Utility Model Content

[0004] The purpose of the utility model is to provide a granulation auxiliary material compression device, which adopts a screening structure and is equipped with a double crushing system, so that larger and agglomerated materials can be crushed again, so that the particle size can be more consistent. At the same time, with the static electricity removal fan, it can effectively prevent subsequent particles from agglomerating again, making the compressor less likely to be blocked.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a granulation auxiliary material compression device, comprising a granulation compressor body 1, an extension cylinder 2 is fixedly connected to the feed inlet at the top of the granulation compressor body 1, a first filter plate 4 is installed in the extension cylinder 2, and the first filter plate 4 is connected to the extension cylinder 2 by an elastic mechanism; a vibration motor 5 is also installed on the extension cylinder 2;

[0006] A crushing chamber 3 is fixed on the side of the extension cylinder 2, and the crushing chamber 3 is provided with a feed port, a crushing roller 11, a crushing knife 13, a second filter plate 14 and a discharge port from top to bottom; a static-eliminating blower 17 is also provided between the second filter plate 14 and the discharge port, and the static-eliminating blower 17 is installed on the side wall of the crushing chamber 3 and communicates with the crushing chamber 3; a drive structure is installed on the side of the crushing chamber 3, and the drive structure is connected to the crushing roller 11 and the crushing knife 13 and drives the crushing roller 11 and the crushing knife 13 to rotate; the feed port of the crushing chamber 3 is communicated with the upper part of the first filter plate 4, and the discharge port of the crushing chamber 3 leads to the top of the particle compressor body 1;

[0007] An extension plate 10 is provided on the side of the first filter plate 4 and extends into the crushing chamber 3 through the feed opening of the crushing chamber 3 .

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0009] The utility model adopts a screening structure with a vibration motor, so that the material can be screened before entering the compressor. At the same time, with the dual crushing system, larger and clumped materials can be crushed again, so that the particle size can be more consistent. At the same time, with the static electricity removal fan, it can effectively prevent subsequent particles from aggregating again, making it less likely to cause clogging when the compressor is working.

[0018] 1. Such as Figure 1-7 The figure shows a granulation auxiliary material compression device, comprising a granulation compressor body 1, an extension cylinder 2 fixedly connected to a feed inlet at the top of the granulation compressor body 1, a first filter plate 4 installed in the extension cylinder 2, and the first filter plate 4 and the extension cylinder 2 are connected by an elastic mechanism; a vibration motor 5 is also installed on the extension cylinder 2;

[0019] A crushing chamber 3 is fixed on the side of the extension cylinder 2, and the crushing chamber 3 is provided with a feed port, a crushing roller 11, a crushing knife 13, a second filter plate 14 and a discharge port from top to bottom; a static-eliminating blower 17 is also provided between the second filter plate 14 and the discharge port, and the static-eliminating blower 17 is installed on the side wall of the crushing chamber 3 and communicates with the crushing chamber 3; a drive structure is installed on the side of the crushing chamber 3, and the drive structure is connected to the crushing roller 11 and the crushing knife 13 and drives the crushing roller 11 and the crushing knife 13 to rotate; the feed port of the crushing chamber 3 is communicated with the upper part of the first filter plate 4, and the discharge port of the crushing chamber 3 leads to the top of the particle compressor body 1;

[0020] An extension plate 10 is provided on the side of the first filter plate 4 and extends into the crushing chamber 3 through the feed opening of the crushing chamber 3 .

[0021] The elastic mechanism includes a support block 6, a spring 7 and a connecting plate 9. Several support blocks 6 are fixed in an annular array on the inner wall of the extension tube 2, and the connecting plate 9 is fixed in an annular array on the outer periphery of the first filter plate 4. The support blocks 6 and the connecting plate 9 are connected by a spring 7.

[0022] Correspondingly, two crushing rollers 11 are provided, and multiple groups of crushing knives 13 are provided, and the multiple groups of crushing knives 13 are installed on the same driving shaft 12 .

[0023] The material after being crushed by the crusher can fall onto the surface of the first filter plate 4. When the vibration motor 5 is started, it will drive the extension cylinder 2 to vibrate, and the vibration can be transmitted to the first filter plate 4 through the support block 6, spring 7 and connecting plate 9. The spring 7 can swing up and down, thereby improving the vibration effect of the first filter plate 4, so that the material can get a better screening effect through the vibration on the surface of the first filter plate 4; when the larger materials after crushing and the agglomerated materials cannot pass through the first filter plate 4, the vibration of the first filter plate 4 will make the materials pass through the extension plate 10 and gradually move toward the top of the crushing rollers 11 on both sides, so that the materials can finally fall between the two crushing rollers 11, and the driving structure can drive the crushing rollers 11 and the driving shaft 12 to rotate. The crushing rollers 11 will perform preliminary crushing on the materials, and then the materials It will fall onto the surface of the second filter plate 14, and the rotation of the crushing knife 13 will be able to cut and crush the material again so that it can completely pass through the second filter plate 14; the double crushing design ensures that the particle size of the material entering the pellet compressor body 1 is more uniform, avoiding the clogging of the compressor die hole due to large material, and the crushed material will fall onto the surface of the discharge plate 15, and return to the inside of the extension cylinder 2 through the discharge plate 15, and finally fall into the inside of the pellet compressor body 1. During this period, the anti-static fan 17 will be in working condition. The anti-static fan 17 releases ionized air to neutralize the static charge on the surface of the material, thereby reducing the electrostatic attraction between fine powders, avoiding the material from solidifying and aggregating again, ensuring the fluidity of the material, and enabling the pellet compressor body 1 to obtain further anti-clogging effect.

[0024] Furthermore, the drive structure includes a mounting base 19, a drive motor 20, a driven shaft 21, a gear 22, and a pulley 23; the mounting base 19 is fixedly connected to the crushing chamber 3, the drive motor 20 is fixedly mounted on the mounting base 19, and the output shaft of the drive motor 20 is connected to the driving shaft 12; the two crushing rollers 11 are coaxially connected to a gear 22, and the gears 22 are meshed with each other. The gears 22 are located outside the crushing chamber 3; one of the gears 22 is also connected to the driven shaft 21;

[0025] A pulley 23 is coaxially mounted on the outer periphery of the driven shaft 21 and the driving shaft 12 , and the two pulleys 23 are conventionally connected via a belt.

[0026] When the drive motor 20 is started, it can drive the driving shaft 12 to rotate, so that the crushing blade 13 can normally perform secondary crushing on the material on the surface of the second filter plate 14. At the same time, the driven structure can also drive the driven shaft 21 on one side to rotate. Through the setting of two meshing gears 22, the driven shaft 21 on the other side can also rotate in the opposite direction, so that the two crushing rollers 11 can rotate in opposite directions, so that the material can be initially crushed. When the driving shaft 12 rotates, the pulley 23 on the surface of the driven shaft 21 will be able to drive the pulley 23 on the surface of the driven shaft 21 to rotate simultaneously through the belt, so that the drive motor 20 can drive the driving shaft 12 and the driven shaft 21 to rotate simultaneously, thereby ensuring normal power transmission.

[0027] A baffle 18 is fixed to the inner wall of the crushing chamber 3 . The baffle 18 is located above the crushing rollers 11 , and the lower edge of the baffle 18 extends to above the space between the two crushing rollers 11 .

[0028] A blanking plate 15 is fixed to the bottom of the inner wall of the crushing chamber 3 . The blanking plate 15 is located below the electrostatic blower 17 and extends to the discharge port of the crushing chamber 3 .

[0029] The baffle 18 acts as a diversion device, blocking the screened material and preventing it from falling into the area other than between the crushing rollers 11. The inclined design of the multiple structures allows the material to flow along the inclined surface more easily. Similarly, the blanking plate 15 also acts as a diversion device.

[0030] An extension shell 16 extending outward is provided on the side wall of the crushing chamber 3 , a static-eliminating blower 17 is installed in the extension shell 16 , and a barrier net 25 is installed inside the extension shell 16 .

[0034] Furthermore, an expansion bucket 8 is fixed to the top of the extension tube 2;

[0035] By providing the expansion bucket 8, the material to be compressed can flow along the surface of the expansion bucket 8 and fall more easily into the interior of the extension tube 2, thereby reducing the amount of material spilling outward.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
