Description

Technical Field

[0001] This utility model relates to the field of plastic crushing technology, and in particular to a crushing device for the production of phenolic molding compounds. Background Technology

[0002] Phenolic molding compounds, as typical thermosetting polymers, are widely used in electrical appliances, machinery, automobiles, and other fields due to their excellent high-temperature resistance, insulation, and mechanical strength. In the production and recycling of waste phenolic molding compounds, large volumes of waste phenolic molding compounds need to be crushed into uniform particles or powder to meet the requirements of subsequent recycling molding and filler reuse processes. Existing crushing devices for phenolic molding compounds mostly adopt an inclined feed inlet design, utilizing the material's own gravity for feeding, and then cutting the material with high-speed rotating blades. While cutting and impact crushing are effective methods, when processing large-volume or barrel-shaped phenolic molding compound products, the material enters the inclined feed inlet and moves towards the crushing area solely by gravity. When the material first comes into contact with the high-speed rotating crushing blades, the blades exert an impact force on the material in the opposite direction of the inlet's inclination, which may cause the material to bounce out, affecting crushing efficiency and safety. At the same time, the initial angle of the material entering the feed inlet is random, and the material can only passively adjust its posture by relying on the rotational force of the crushing blades. Crushing can only begin after the crushing blades have rotated the material to an effective crushing angle, thus reducing overall processing efficiency. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] In view of the problems existing in the above and / or existing crushing devices for the production of phenolic molding compounds, this utility model is proposed.

[0005] Therefore, the problem to be solved by this utility model is that when the inclined feed inlet crushing device processes large-volume phenolic molding compounds, the material is prone to popping out due to the reverse force of the crushing blade.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1 Reference Figures 1-6 This is the first embodiment of the present invention, which provides a crushing device for the production of phenolic molding compounds. The crushing device for the production of phenolic molding compounds includes a main component 1, including a frame 11. A crushing mechanism is provided inside the frame 11. A power mechanism is provided on one side of the frame 11. The power mechanism drives the crushing blade to rotate and crush the plastic parts. A feeding rack 12 is fixed on one side of the frame 11. The bottom of the feeding rack 12 is tilted upward at a certain angle. The plastic parts to be crushed enter the crushing area through the feeding rack 12. A shielding strip is provided at the connection between the feeding rack 12 and the interior of the frame 11 to prevent small particles generated during crushing from splashing. This is the prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0031] The auxiliary component 2, located on the feed rack 12, includes an auxiliary part 21. By setting the auxiliary part 21, the material to be crushed can be forcibly fed to ensure crushing efficiency and safety.

[0032] The auxiliary component 21 includes a rotating column 211 slidably mounted on the feed rack 12. A pusher plate 212 is fixed on the rotating column 211. The feed rack 12 has a moving groove 12-1 in which the rotating column 211 slides. A moving block 213 is connected to one side of the rotating column 211 by a bearing. A reciprocating roller 214 is inserted into the moving block 213. A motor 215 is mounted on one side of the reciprocating roller 214. The output end of the motor 215 is connected to the reciprocating roller 214. A slider 218 is fixed on the moving block 213. The slider 218 slides in the spiral groove of the reciprocating roller 214. As the reciprocating roller 214 rotates, the slider 218 slides in the spiral groove. Since the moving block 213 cannot rotate, it will drive the moving block 213 to reciprocate along the direction of the reciprocating roller 214. The motor 215 can change the feeding speed to adapt to the feeding speed.

[0033] The motor 215 starts and drives the reciprocating roller 214 to rotate, which in turn causes the moving block 213 to move along the direction of the reciprocating roller 214. This causes the rotating column 211 to slide along the moving groove 12-1, thereby driving the pusher plate 212 to move into the crushing area inside the frame 11. This forces the plastic parts to be fed, counteracting the reverse impact force of the crushing blade on the material. This effectively prevents the material from being ejected from the feed port due to the reverse force overcoming gravity, avoiding interruption of the crushing process. At the same time, it eliminates the risk of large-volume material ejection. Meanwhile, the pusher plate 212 reduces the safety threat to operators from large-volume material splashing.

[0034] The auxiliary component 2 also includes a rotating component 22 located on both sides of the rotating column 211. The rotating component 22 allows the pusher plate 212 to rotate. When pushing material towards the frame 11, the angle of the pusher plate 212 is fixed, which facilitates pushing the material forward. During the reset process away from the frame 11, the pusher plate 212 will rotate to avoid pushing the next material to move in the opposite direction.

[0035] The rotating component 22 includes a fixed sleeve 221 fixed to the rotating column 211. A gear 222 is slidably disposed on the fixed sleeve 221. A rack 223 is fixed on the inner wall of the feed rack 12. The gear 222 can mesh with the rack 223. Since the gear 222 can slide on the fixed sleeve 221, when the gear 222 is close to the inner wall of the feed rack 12, the gear 222 engages with the rack 223. At this time, when the moving block 213 drives the rotating column 211 to slide along the moving groove 12-1, the gear 222 will rotate under the action of the rack 223. This state corresponds to the pusher plate 212 resetting. When the gear 222 is away from the inner wall of the feed rack 12, the gear 222 does not engage with the rack 223. At this time, the rotating column 211 slides in the moving groove 12-1, and the gear 222 will not rotate. This state corresponds to the pusher plate 212 pushing material.

[0036] Example 2 Reference Figures 2-7This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, the bearings at both ends of the reciprocating roller 214 are connected to support blocks 216, which are fixed on the feed frame 12. The support blocks 216 are used to support the reciprocating roller 214. A support frame is fixed on the motor 215, which is fixed to the frame 11 and supports the motor 215.

[0038] A slide bar 217 is provided on the other side of the feed rack 12. Support blocks 216 are fixed at both ends of the slide bar 217. The support blocks 216 support the slide bar 217. A moving block 213 is also slidably provided on the slide bar 217. There are two moving blocks 213 in total, which are respectively connected to the two ends of the rotating column 211 by bearings. Under the action of the two moving blocks 213, the reciprocating roller 214 and the slide bar 217, the rotating column 211 can slide smoothly in the moving groove 12-1.

[0039] Specifically, a protrusion 224 is fixed on the fixed sleeve 221, and a groove 222-1 is provided on the gear 222. The protrusion 224 slides in the groove 222-1. There are two protrusions 224, and the number of grooves 222-1 corresponds to the number of protrusions 224. With the cooperation of the protrusions 224 and the grooves 222-1, the gear 222 can slide relative to each other on the fixed sleeve 221, and the two can rotate at the same time.

[0040] Specifically, there are two shielding sleeves 23 fixed inside the feed rack 12, located on both sides inside the feed rack 12 respectively. There are two sets of rotating parts 22, located inside the two shielding sleeves 23 respectively. The shielding sleeves 23 protect the rotating parts 22.

[0041] Specifically, the shielding sleeve 23 has a first extrusion block 226 and a second extrusion block 227 fixed inside. Both of them have inclined surfaces. The first extrusion block 226 is located away from the frame 11, while the second extrusion block 227 is located close to the frame 11.

[0042] The rack 223 has two segments with no intermediate segments. One segment is located near the frame 11 and is used to tilt the pusher plate 212 during the reset phase. The tilt angle of the pusher plate 212 will be the same as the angle of the feed rack 12. At this time, the pusher plate 212 is located above the inner wall of the feed rack 12, so that even if there is material in the feed rack 12, the material will move in the opposite direction. The other segment is located away from the frame 11 and is used to make the pusher plate 212 continue to rotate during the reset phase, so that the pusher plate 212 rotates one revolution to complete the final angle reset. At this time, the pusher plate 212 will be perpendicular to the ground.

[0043] The thickness of the first extrusion block 226 and the second extrusion block 227 is greater than the distance between adjacent teeth of the gear 222.

[0044] When the pusher plate 212 gradually moves to a position away from the frame 11, the inclined surface of the first extrusion block 226 will apply a pushing force to the gear 222, thereby causing the gear 222 to move away from the inner wall of the feed rack 12 and eventually separate from the rack 223. It will not be coplanar with the rack 223, so that the rack 223 will not drive the gear 222 to rotate. At this time, the angle of the pusher plate 212 will not change easily.

[0045] As the pusher plate 212 gradually approaches the frame 11, the inclined surface of the second extrusion block 227 will apply a pushing force to the gear 222, causing the gear 222 to move towards the inner wall of the feed rack 12 and become coplanar with the rack 223. Then the rack 223 can drive the gear 222 to rotate, and the pusher plate 212 can rotate.

[0046] When gear 222 moves to the end of rack 223, that is, when it moves to the vicinity of the first pressing block 226 and the second pressing block 227, the teeth on rack 223 do not mesh with gear 222. At this time, gear 222 will not rotate. Gear 222 can rotate one full turn along moving rack 223.

[0047] Example 3 Reference Figures 8-10 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0048] Specifically, the auxiliary component 2 also includes a locking member 24 located inside the shielding sleeve 23. The locking member 24 is configured to lock the angle of the pusher plate 212 during material feeding, thereby ensuring a stable pushing force is applied to the plastic part and thus enabling forced feeding.

[0049] The fixed sleeve 221 is covered with a movable plate 241, and the cover sleeve 23 is fixed with a slide rail 242. The movable plate 241 slides in the slide rail 242. With the cooperation of the slide rail 242, the movable plate 241 can move horizontally but will not rotate.

[0050] Specifically, the movable plate 241 has a lifting groove 241-1, and a locking block 243 is slidably disposed in the lifting groove 241-1. The inner wall of the lifting groove 241-1 has a large roughness, so that when the locking block 243 moves in it, a large force needs to be applied. Without a large external force, the locking block 243 will not easily change its position in the lifting groove 241-1. The locking block 243 has a small inclined surface 243-1 and a large inclined surface 243-2.

[0051] The fixed sleeve 221 has a locking groove 221-1 corresponding to the locking block 243. When the two are engaged, the fixed sleeve 221 and the moving plate 241 will be locked. At this time, the fixed sleeve 221 cannot rotate, thereby locking the angle of the push plate 212. At this time, the push plate 212 is perpendicular to the ground.

[0052] Specifically, auxiliary blocks 244 are fixed at both ends of the slide rail 242. A first push block 245 and a second push block 246 are fixed on the two auxiliary blocks 244 respectively. The first push block 245 is located away from the frame 11, while the second push block 246 is located close to the frame 11. Both the first push block 245 and the second push block 246 have inclined surfaces. The first push block 245 can fit with the small inclined surface 243-1, while the second push block 246 can fit with the large inclined surface 243-2.

[0053] Specifically, the movable plate 241 has a first through slot 241-2 and a second through slot 241-3, which correspond to the first push block 245 and the second push block 246, respectively.

[0054] As the pusher plate 212 gradually moves to its limit position away from the frame 11, as the moving plate 241 continues to move, the first pusher block 245 will contact the small inclined surface 243-1 of the locking block 243 through the first through groove 241-2, causing the locking block 243 to move upward and engage with the locking groove 221-1, thereby limiting the angle of the pusher plate 212 and making it perpendicular to the ground.

[0055] As the pusher plate 212 gradually moves to its limit position near the frame 11, the moving plate 241 will also gradually move away from the frame 11. As the moving plate 241 continues to move, the second pusher block 246 gradually approaches the frame 11. The second pusher block 246 contacts the large inclined surface 243-2 of the locking block 243 through the second through groove 241-3 and applies a pushing force to it, thereby causing the locking block 243 to move downward and away from the locking groove 221-1, thereby releasing the angle restriction of the pusher plate 212 and facilitating subsequent reset.

[0056] Specifically, a number of friction blocks are fixed on the locking block 243, and a number of friction blocks are also fixed on the upper surface of the shielding sleeve 23. The friction blocks on the surface of the locking block 243 increase the friction between the locking block 243 and the lifting groove 241-1, so that the weight of the locking block 243 will not change its position when there is no other external force.

[0057] The friction block on the upper surface of the shielding sleeve 23 can restrict the rotation of the gear 222. When the tooth block on the rack 223 is not meshing with the gear 222, the rotation angle of the gear 222 will not change arbitrarily under the action of the friction block.

[0058] During use, the motor 215 starts and drives the reciprocating roller 214 to rotate, which in turn causes the moving block 213 to move along the direction of the reciprocating roller 214. This causes the rotating column 211 to slide along the moving groove 12-1, and drives the pusher plate 212 to move into the crushing area inside the frame 11. At this time, the locking block 243 engages with the locking groove 221-1, limiting the angle of the pusher plate 212 so that it is perpendicular to the ground. At the same time, the gear 222 is not coplanar with the rack 223, and the rack 223 will not drive the gear 222 to rotate. At this time, the angle of the pusher plate 212 will not change easily, so that the pusher plate 212 can force-feed the plastic parts and move them into the crushing area. This counteracts the reverse impact force of the crushing blade on the material, effectively preventing the material from being ejected from the feed port due to the reverse force overcoming gravity, avoiding interruption of the crushing process, and eliminating the risk of large-volume materials being ejected.

[0059] As the pusher plate 212 gradually moves to its limit position near the frame 11, the moving plate 241 will also gradually move away from the frame 11. As the moving plate 241 continues to move, the second pusher block 246 gradually approaches the frame 11. The second pusher block 246 contacts the large inclined surface 243-2 of the locking block 243 through the second through groove 241-3 and applies a pushing force to it, thereby causing the locking block 243 to move downward and away from the locking groove 221-1, thus releasing the angle restriction of the pusher plate 212. At the same time, the second pusher block 246... The inclined surface of the second extrusion block 227 will apply a thrust to the gear 222, causing the gear 222 to move towards the inner wall of the feed rack 12 and become coplanar with the rack 223. Then the rack 223 can drive the gear 222 to rotate, and the pusher plate 212 can rotate. Then the rotating column 211 will move away from the frame 11 along the moving groove 12-1, and the pusher plate 212 will reset. Then the angle locking of the pusher plate 212 will be triggered again, and at the same time the gear 222 will be triggered to move away from the rack 223 and engage, thereby repeating the forced feeding process.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
