Description

Technical Field

[0001] This invention relates to the field of polypropylene processing technology, and in particular to a crushing and processing apparatus for polypropylene composite materials. Background Technology

[0002] Polypropylene is a polymer formed by the addition polymerization of propylene. It has excellent mechanical properties, including tensile strength, compressive strength and hardness, as well as outstanding rigidity and resistance to flexural fatigue.

[0003] In the prior art, patent document with publication number (CN216359060U) mentions a crushing and processing device for polypropylene composite materials, including a base, a support frame fixedly installed at the upper edge of the base, a crushing box fixedly installed at the upper end of the support frame, a feeding box fixedly installed at the upper middle of the crushing box, and a condensate pipe fixedly installed inside the feeding box. The condensate pipe cools and solidifies the heated polypropylene material, preventing the fluidized polypropylene material from entering the crushing box and failing to be properly crushed, and finally falling into the separation box to re-solidify, which would damage the screen plate in the separation box, affecting separation and the crushing process of the polypropylene material. By clamping and fixing the limiting slide plate, the lifting and lowering of the separation box can be controlled by the action of a cylinder, which facilitates the need to change the limiting slide plate and screen plate to different apertures, and also facilitates the collection of the separated polypropylene material, allowing insufficiently crushed particles to be crushed again.

[0004] However, in the aforementioned existing technology, some raw materials fall from the outside of the crushing chamber during crushing and cannot be crushed, thus affecting the crushing effect. Summary of the Invention

[0005] The purpose of this invention is to provide a crushing and processing device for polypropylene composite materials, which solves the problem in the prior art that some raw materials fall from the outside of the crushing box during crushing and cannot be crushed, thus affecting the crushing effect.

[0006] To achieve the above objectives, the present invention provides a crushing and processing device for polypropylene composite materials, comprising a housing and a crushing mechanism.

The rotating ring is fixedly connected to the connecting frame and located outside the connecting frame. Several fixed rings are fixedly connected to the housing and are evenly arranged inside the housing. Openings are provided on the surfaces of both the fixed rings and the rotating ring. Several cutters are fixedly connected to the rotating rod and are respectively arranged below the rotating ring and the corresponding fixed ring. The feeding assembly is located on one side of the first motor.

[0007] The crushing mechanism further includes several raised strips, which are fixedly connected to the rotating ring and are evenly distributed on the surface of the rotating ring.

[0008] The feeding assembly includes a feeding port and a sealing structure. The feeding port is fixedly connected to the housing and located on one side of the first motor. The sealing structure is disposed above the feeding port.

[0009] The enclosed structure includes a sliding plate and two fixed blocks. The sliding plate is slidably connected to the feed inlet and is located on one side of the feed inlet. The two fixed blocks are fixedly connected to the sliding plate and the feed inlet respectively and are located on one side of the feed inlet. The two fixed blocks are bolted together.

[0010] The enclosed structure further includes a retaining strip, which is fixedly connected to the sliding piece and located on the side of the sliding piece away from the fixed block.

[0011] The pulverizing and processing device for the polypropylene composite material further includes a filter plate and a fixing structure. The filter plate is slidably connected to the housing and located below the rotating rod. The fixing structure is disposed on one side of the filter plate.

[0012] The fixing structure includes a limiting ring and two mounting plates. The limiting ring is fixedly connected to the filter plate and is located on one side of the filter plate. The two mounting plates are fixedly connected to the limiting ring and the housing respectively and are located on one side of the housing. The two mounting plates are bolted together.

[0013] This invention discloses a crushing and processing device for polypropylene composite materials. A first motor is fixedly connected to a housing and located above the housing. A rotating rod is fixedly connected to the output end of the first motor and located inside the housing. A connecting frame is fixedly connected to the rotating rod and located at its upper end. A rotating ring is fixedly connected to the connecting frame and located outside the connecting frame. A plurality of fixed rings are fixedly connected to the housing and evenly arranged inside the housing. Openings are provided on the surfaces of both the fixed rings and the rotating ring. A plurality of cutters are fixedly connected to the rotating rod and respectively disposed below the rotating ring and the corresponding fixed ring. A feeding assembly is located on one side of the first motor, feeding raw materials into the housing through the feeding assembly. The first motor drives the rotating rod to rotate, and the rotating ring rotates accordingly. As the raw material reaches the surface of the rotating ring, it falls through the opening. The cutters cut the raw material. Under the constraint of the fixed rings and the rotating ring, the raw material moves towards the center of the housing, preventing it from falling onto the side wall of the housing. This allows the raw material to be repeatedly cut by the cutters, improving the crushing effect. Attached Figure Description

Detailed Implementation

[0026] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0027] First embodiment:

[0028] Please see Figures 1-4 ,in, Figure 1 This is a structural schematic diagram of the first embodiment. Figure 2 yes Figure 1 A schematic diagram of the structure at point A. Figure 3 This is a front view of the first embodiment. Figure 4 yes Figure 3 BB line section view.

[0029] This invention provides a crushing and processing device for polypropylene composite materials, including a housing 101 and a crushing mechanism. The crushing mechanism includes a first motor 102, a rotating rod 103, a connecting frame 104, a rotating ring 105, several fixed rings 106, several cutters 107, several protruding strips 108, and a feeding assembly. The feeding assembly includes a feeding port 109 and a closing structure. The closing structure includes a retaining strip 110, a sliding plate 111, and two fixing blocks 112. The aforementioned solution solves the problem in the prior art where, during crushing, some raw materials fall from the outside of the crushing box and cannot be crushed, thus affecting the crushing effect.

[0030] In this specific embodiment, the first motor 102 is fixedly connected to the housing 101 and located above the housing 101. The rotating rod 103 is fixedly connected to the output end of the first motor 102 and located inside the housing 101. The connecting frame 104 is fixedly connected to the rotating rod 103 and located at the upper end of the rotating rod 103. The rotating ring 105 is fixedly connected to the connecting frame 104 and located outside the connecting frame 104. A plurality of fixing rings 106 are fixedly connected to the housing 101 and are evenly arranged inside the housing 101. The surfaces of the fixing rings 106 and the rotating rings 105 are provided with openings 113. A plurality of cutters 107 are connected to the rotating rod. 103 is fixedly connected and respectively set below the rotating ring 105 and the corresponding fixed ring 106. The feeding assembly is set on one side of the first motor 102. The raw material is added into the interior of the box 101 through the feeding assembly. The first motor 102 drives the rotating rod 103 to rotate, and the rotating ring 105 rotates accordingly. When the raw material is fed onto the surface of the rotating ring 105, it falls from the opening 113. The cutter 107 cuts the raw material. Under the restriction of the fixed ring 106 and the rotating ring 105, the raw material moves towards the center of the box 101 to prevent the raw material from falling onto the side wall of the box 101. The raw material is repeatedly cut by several cutters 107, which improves the crushing effect.

[0031] Among them, several of the protruding strips 108 are fixedly connected to the rotating ring 105 and are evenly arranged on the surface of the rotating ring 105. After the raw material falls onto the surface of the rotating ring 105, each of the protruding blocks drives a part of the raw material to move, so that the raw material falls evenly into the interior of the box 101.

[0032] Secondly, the feed inlet 109 is fixedly connected to the housing 101 and located on one side of the first motor. The sealing structure is set above the feed inlet 109, allowing the raw material to fall into the interior of the housing 101 through the feed inlet 109. The sealing structure seals the feed inlet 109 to prevent the raw material from splashing to the outside of the housing 101.

[0033] Secondly, the sliding plate 111 is slidably connected to the feed inlet 109 and is located on one side of the feed inlet 109. The two fixing blocks 112 are fixedly connected to the sliding plate 111 and the feed inlet 109 respectively and are located on one side of the feed inlet 109. The two fixing blocks 112 are bolted together. The raw material is added into the interior of the box 101 through the feed inlet 109. The sliding plate 111 is slid to close the feed inlet 109, and the two fixing blocks 112 are fixed by bolts.

[0034] In addition, the locking strip 110 is fixedly connected to the sliding piece 111 and is located on the side of the sliding piece 111 away from the fixing block 112. The locking strip 110 restricts the position of the sliding piece 111 and prevents the sliding piece 111 from leaving the feed port 109.

[0035] When using this invention, the raw material is added into the interior of the housing 101 through the feed inlet 109. The sliding plate 111 is slid to close the feed inlet 109, preventing the sliding plate 111 from detaching from the feed inlet 109. The two fixing blocks 112 are fixed by bolts. The first motor 102 drives the rotating rod 103 to rotate, and the rotating ring 105 rotates accordingly. When the raw material is fed onto the surface of the rotating ring 105, it falls from the opening 113. The cutter 107 cuts the raw material. Under the restriction of the fixing ring 106 and the rotating ring 105, the raw material moves towards the center of the housing 101, preventing the raw material from falling onto the side wall of the housing 101. This allows the raw material to be repeatedly cut by several cutters 107, improving the crushing effect.

[0036] Second embodiment:

[0037] Please see Figures 5-7 ,in, Figure 5 This is a structural schematic diagram of the second embodiment. Figure 6 This is a front view of the second embodiment. Figure 7 yes Figure 6 CC-line sectional view.

[0038] Based on the first embodiment, the present invention provides a crushing and processing device for polypropylene composite materials, including a filter plate 201 and a fixing structure. The fixing structure includes a limiting ring 202 and two mounting plates 203. The aforementioned solution solves the problem that the raw materials are difficult to crush completely and that larger raw materials cannot be discharged.

[0039] In this specific embodiment, the filter plate 201 is slidably connected to the housing 101 and is located below the rotating rod 103. The fixing structure is set on one side of the filter plate 201. After the raw material is crushed, it falls onto the surface of the filter plate 201. The raw material that meets the filter standard is filtered by the filter plate 201, while larger raw materials stay on the surface of the filter plate 201.

[0040] The limiting ring 202 is fixedly connected to the filter plate 201 and is located on one side of the filter plate 201. The two mounting plates 203 are fixedly connected to the limiting ring 202 and the housing 101 respectively and are located on one side of the housing 101. The two mounting plates 203 are bolted together. After filtration, the filter plate 201 is pulled out through the limiting ring 202, and larger raw materials are taken out with it.

[0041] When using this invention, the raw material is added into the interior of the housing 101 through the feed inlet 109. The sliding plate 111 is slid to close the feed inlet 109, preventing the sliding plate 111 from detaching from the feed inlet 109. The two fixing blocks 112 are fixed by bolts. The first motor 102 drives the rotating rod 103 to rotate, and the rotating ring 105 rotates accordingly. The raw material is fed onto the surface of the rotating ring 105 and falls from the opening 113. The cutter 107 cuts the raw material. Under the restriction of the fixing ring 106 and the rotating ring 105, the raw material moves towards the center of the housing 101, preventing the raw material from falling onto the side wall of the housing 101. After being crushed, the raw material falls onto the surface of the filter plate 201. The raw material passes through the filter plate 201 and meets the filter standard. Larger raw materials stop on the surface of the filter plate 201. The filter plate 201 is pulled out by the limiting ring 202, and the larger raw materials are taken out with it.

[0042] Third embodiment:

[0043] The pulverizing and processing device for the polypropylene composite material also includes a discharge mechanism, which is located below the filter plate 201.

[0044] The discharge mechanism includes a cooling box 301, a second motor 302, and a rotating frame 304. The cooling box 301 is fixedly connected to the box body 101 and located below the box body 101. The second motor 302 is fixedly connected to the cooling box 301 and located below the cooling box 301. The rotating frame 304 is fixedly connected to the output end of the second motor 302 and located inside the cooling box 301.

[0045] The discharge mechanism also includes a cooling pipe 303, which is disposed inside the second housing 101 and has both ends passing through the cooling housing 301.

[0046] Please see Figures 8-10 ,in, Figure 8 This is a structural schematic diagram of the second embodiment. Figure 9 This is a front view of the second embodiment. Figure 10 yes Figure 9 DD-line sectional view.

[0047] Based on the second embodiment, the present invention provides a crushing and processing device for polypropylene composite materials, including a discharge mechanism. The discharge mechanism includes a cooling box 301, a second motor 302, a cooling pipe 303, and a rotating frame 304. The aforementioned solution solves the problem of high raw material temperature after crushing.

[0048] In this specific embodiment, the discharge mechanism is located below the filter plate 201, and the discharge assembly discharges the raw material after it has cooled.

[0049] The cooling box 301 is fixedly connected to the box body 101 and located below the box body 101. The second motor 302 is fixedly connected to the cooling box 301 and located below the cooling box 301. The rotating frame 304 is fixedly connected to the output end of the second motor 302 and located inside the cooling box 301. The raw material falls into the box body 101 through the filter plate 201. The second motor 302 drives the rotating frame 304 to rotate, and the rotating frame 304 stirs the raw material to accelerate its cooling.

[0050] Secondly, the cooling pipe 303 is installed inside the second box 101, and both ends of the cooling pipe 303 pass through the cooling box 301, so that cooling water is injected into the interior of the cooling pipe 303 to cool the raw materials.

[0051] When using this invention, the raw material is added into the housing 101 through the feed inlet 109. The sliding plate 111 is slid to close the feed inlet 109, preventing the sliding plate 111 from detaching from the feed inlet 109. The two fixing blocks 112 are fixed with bolts. The first motor 102 drives the rotating rod 103 to rotate, and the rotating ring 105 rotates accordingly. The raw material is fed onto the surface of the rotating ring 105 and falls from the opening 113. The cutter 107 cuts the raw material. Under the constraint of the fixing ring 106 and the rotating ring 105, the raw material flows into the housing 101. The center moves to prevent raw materials from falling onto the side wall of the housing 101. After being crushed, the raw materials fall onto the surface of the filter plate 201. The raw materials that meet the standards after being filtered by the filter plate 201 are filtered. Larger raw materials stop on the surface of the filter plate 201. The filter plate 201 is pulled out by the limiting ring 202, and the larger raw materials are also taken out. The raw materials fall into the interior of the housing 101 through the filter plate 201. Cooling water is injected into the interior of the cooling pipe 303 to cool the raw materials. The second motor 302 drives the rotating frame 304 to rotate. The rotating frame 304 stirs the raw materials and accelerates the cooling of the raw materials.

[0052] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
