Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to an orientation mixing structure for plastic product manufacturing. Background Technique

[0002] Plastic products are various products processed and formed through processes such as extrusion, injection molding, blow molding, calendering, and laminating, with synthetic resin as the main raw material. During the production process, a mixing device is usually used to uniformly disperse and tightly combine various raw materials, including synthetic resin, additives, fillers, etc., under the action of specific temperature, pressure, and shear force through mechanical mixing. However, the existing mixing devices still have certain deficiencies when in use.

[0003] For example, a high-speed rotating plastic mixer with the publication number CN218748698U. It pours materials into the feeding box through a feeding pipe. At this time, the driving motor can be started to drive the rotating rod to rotate. Subsequently, the rotating rod can drive the second gear to rotate through meshing of the first gear, so that the second gear can drive three symmetrically distributed guide rods to revolve, enabling the materials in the feeding box to be mixed by the force applied by the guide rods, achieving the effect of facilitating mixing and preventing the situation that the materials poured into the operating equipment during use are inconvenient to mix in advance, resulting in uneven mixing between the materials during the use of the operating equipment, affecting the use effect, and requiring secondary operations. However, the feeding port of this device is relatively small. When plastic enters the mixer for mixing, the plastic may accumulate at the feeding port, making it impossible to leak into the mixer for mixing, thus resulting in the inability to smoothly mix plastic products. At the same time, it is not convenient to clean the inside of the material box, and the operator needs to spend more time for disassembly, reducing production efficiency.

[0004] Therefore, we propose an orientation mixing structure for plastic product manufacturing to facilitate solving the problems raised above. Content of the Utility Model

[0009] The output end of the electric push rod is fixedly connected with a plug rod, and the bottom end of the plug rod penetrates into the rotating rod, and a slider is fixedly connected to the outer wall of the plug rod;

[0010] A connecting sleeve is rotatably connected to the filter plate, a straight groove is opened in the connecting sleeve, and a lower abutting block is arranged on the outer wall of the connecting sleeve.

[0011] Preferably, the connecting mechanism includes a first clamping block and a second clamping block. Two first clamping blocks are symmetrically arranged with respect to the feed box body, and both of the two first clamping blocks are fixedly connected to the outer wall of the feed box body. Card slots are opened in both of the two first clamping blocks, and the opening directions of the two card slots are opposite. Two second clamping blocks are symmetrically arranged with respect to the cover plate, and the second clamping blocks are fixedly connected to the outer wall of the cover plate. The two second clamping blocks are arranged in an "L" shape, and the cross section of the two card slots is matched with the second clamping block.

[0012] Preferably, the plug rod is slidably connected to the rotating rod, one end of the slider on the plug rod extends into the spiral groove, and the slider is slidably connected to the spiral groove. The bottom end of the plug rod is aligned with the guide pipe.

[0013] Preferably, a sliding groove is opened in the inner bottom end of the feed box body.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: The directional mixing structure for plastic product manufacturing can prevent plastics from staying and accumulating in the guide pipe during feeding, avoid the occurrence of blockage phenomena, improve production efficiency, and at the same time facilitate the cleaning of the inside of the feed box body, avoid plastic residue, and reduce maintenance costs. The specific content is as follows:

[0017] 1. There is a plug rod, which works through an electric push rod, driving the plug rod to reciprocate up and down along the inner wall of the rotating rod, so that the plug rod intermittently inserts into the material guiding pipe, thereby extruding the material in the material guiding pipe, realizing the rapid dredging of the material guiding pipe, with a simple structure, improving the stability and continuity of the production line.

[0018] 2. There are spiral grooves and sliders. When the plug rod reciprocates up and down, it will drive the slider to slide along the spiral groove, so that the rotating rod drives the stirring blades to stir the material. Then the rotating rod will drive the connecting sleeve to rotate, making the lower abutting block at the bottom of the connecting sleeve slide along the surface of the upper abutting block, thereby squeezing the upper abutting block, so that the upper abutting block drives the filter plate to slide downwards, squeezing the compression spring to contract. Then when the lower abutting block is separated from the upper abutting block, the elastic force of the compression spring drives the filter plate to reset, making the filter plate vibrate, thereby improving the screening effect.

[0019] 3. There are a first clamping block and a second clamping block. By unscrewing the bolt connecting the first clamping block and the second clamping block, and then rotating the cover plate, the cover plate drives the second clamping block to rotate, so that the second clamping block is separated from the clamping groove, and the cover plate can be quickly removed. The structure is simple and it is convenient to clean the inside of the feed box body. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0028] Embodiment 1: Please refer to Figures 1-6 As shown, the present utility model provides a technical solution: an orientation mixing structure for manufacturing plastic products, including a feed box body 1, a guide pipe 2 is fixedly connected to the bottom end of the feed box body 1, a cover plate 3 is arranged at the upper end of the feed box body 1, and an electric push rod 4 is fixedly connected to the upper end of the cover plate 3.

[0029] With the setting of the feed box body 1 in this technical solution, during use, first place the feed box body 1 on the mixing device, align the guide pipe 2 at the bottom end of the feed box body 1 with the inner cavity of the mixing device, and then fasten the feed box body 1 with bolts to prevent the feed box body 1 from shaking during the feeding process. Further, connect the cover plate 3 to the feed box body 1, and then the mixing of plastic products can be carried out.

[0030] Embodiment 2: The technical content disclosed in this embodiment is an improvement based on Embodiment 1 above. The existing one is not convenient for cleaning the inside of the feed box, and the operator needs to spend more time for disassembly, reducing production efficiency. This technical solution is as Figure 4 and Figure 5 As shown, a disassembly component of a mixer is disclosed. A filter plate 5 is slidably connected to the inner bottom end of the feed box body 1, and the feed box body 1 and the cover plate 3 are connected to each other through a connection mechanism. The connection mechanism includes a first clamping block 15 and a second clamping block 16. There are two first clamping blocks 15 symmetrically arranged with respect to the feed box body 1, and both two first clamping blocks 15 are fixedly connected to the outer wall of the feed box body 1. A clamping groove 1501 is opened in each of the two first clamping blocks 15, and the opening directions of the two clamping grooves 1501 are opposite. There are two second clamping blocks 16 symmetrically arranged with respect to the cover plate 3, and the second clamping blocks 16 are fixedly connected to the outer wall of the cover plate 3. The two second clamping blocks 16 are arranged in an "L" shape, and the cross section of the two clamping grooves 1501 matches the second clamping blocks 16. And screw holes are opened on both the first clamping block 15 and the second clamping block 16.

[0031] In this technical solution, as Figure 4As shown, by setting the first clamping block 15 and the second clamping block 16, when removing the screw connecting the second clamping block 16 and the first clamping block 15, rotating the cover plate 3 will drive the second clamping block 16 to rotate, so as to separate from the first clamping block 15 and release the limit on the cover plate 3. The structure is simple and convenient for cleaning the inside of the feed box body 1.

[0032] It adopts the technical solution as Figure 5 shown. When it is necessary to clean the inside of the feed box body 1, first remove the screw installed on the first clamping block 15 and the second clamping block 16, and then rotate the cover plate 3, so that the cover plate 3 drives the second clamping block 16 to rotate, thereby separating the second clamping block 16 from the card slot 1501, and the limit on the cover plate 3 can be released. Then, pull up the cover plate 3 to remove it, which is convenient for cleaning the inside of the feed box body 1. During installation, it is necessary to align the raised block 601 with the straight groove 12 first, and then press down the cover plate 3, so that the raised block 601 slides into the straight groove 12. When the cover plate 3 fits against the outer wall of the top end of the feed box body 1, rotate the cover plate 3 so that the second clamping block 16 on the cover plate 3 rotates and slides into the card slot 1501. At this time, use bolts to align and tighten, and the installation efficiency is high.

[0033] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned Embodiment 1 and Embodiment 2. Since the feed inlet of this device is relatively small, when plastics enter the mixer for mixing, the plastics may accumulate at the feed inlet, making it impossible to leak into the mixer for mixing, thus resulting in the inability to mix plastic products smoothly. To further solve this technical problem, the technical solution is as Figures 1-3 and Figure 6As shown, an anti-blocking component of a mixer is disclosed. A rotating rod 6 is rotatably connected to the bottom end of a cover plate 3, and a stirring blade 7 is fixedly connected to the outer side of the rotating rod 6. A raised block 601 is fixedly connected to the outer wall of the rotating rod 6 below the stirring blade 7, and a spiral groove 8 is provided inside the rotating rod 6. The output end of an electric push rod 4 is fixedly connected to an insertion rod 10, and the bottom end of the insertion rod 10 penetrates into the rotating rod 6. A sliding block 9 is fixedly connected to the outer wall of the insertion rod 10. A connecting sleeve 11 is rotatably connected inside a filter plate 5, a straight groove 12 is formed inside the connecting sleeve 11, and a lower abutting block 13 is provided on the outer wall of the connecting sleeve 11. A upper abutting block 14 is fixedly connected to the middle of the upper end of the filter plate 5. The straight groove 12 is fitted with the raised block 601 at the bottom end of the rotating rod 6. The insertion rod 10 is slidably connected to the rotating rod 6, and one end of the sliding block 9 on the insertion rod 10 extends into the spiral groove 8, and the sliding block 9 is slidably connected to the spiral groove 8. The bottom end of the insertion rod 10 is aligned with the material guide pipe 2. A sliding groove is formed at the bottom end inside the feed hopper body 1. The outer end of the filter plate 5 is located in the sliding groove, and a compression spring 501 is fixedly connected between the bottom of the outer end of the filter plate 5 and the bottom wall of the sliding groove. A plurality of lower abutting blocks 13 are arranged in a circumferential array with respect to the midpoint of the connecting sleeve 11, and the lower abutting blocks 13 are arranged in a semi-circular structure. A plurality of upper abutting blocks 14 are arranged in a circumferential array with respect to the midpoint of the filter plate 5, and inclined surfaces are formed at both ends of the upper abutting blocks 14, and the inclined surfaces on the upper abutting blocks 14 are in mutual contact with the lower abutting blocks 13.

[0034] In this technical solution, as Figure 1 shown, by the arrangement of the insertion rod 10, when the materials in the material guide pipe 2 accumulate and block the material guide pipe 2, the electric push rod 4 will push the insertion rod 10 to move, so that the insertion rod 10 is inserted into the material guide pipe 2 to extrude the materials in the material guide pipe 2, without manual intervention, greatly improving the production efficiency and safety.

[0035] It adopts such as Figure 2 and Figure 3 、 Figure 6In the shown technical solution, first, when in use, the material is placed into the feed box body 1. Immediately afterwards, the electric push rod 4 is started. The electric push rod 4 drives the insertion rod 10 to move up and down reciprocally. When the insertion rod 10 moves, it drives the slider 9 to move. The slider 9 slides along the spiral groove 8, thereby driving the rotating rod 6 to rotate. When the rotating rod 6 rotates, it drives the convex block 601 and the stirring blade 7 to rotate simultaneously. When the stirring blade 7 rotates, it stirs the material in the feed box body 1. The convex block 601 is located in the straight groove 12, so that when the convex block 601 rotates, it drives the connecting sleeve 11 to rotate. The connecting sleeve 11 drives the lower abutting block 13 to rotate synchronously, so that the lower abutting block 13 intermittently slides on the surface of the upper abutting block 14. When the lower abutting block 13 abuts against the upper abutting block 14, at this time, the upper abutting block 14 is squeezed and moves downward, thereby driving the filter plate 5 to move downward synchronously and compressing the compression spring 501 to contract. When the lower abutting block 13 is separated from the upper abutting block 14, the elastic force of the compression spring 501 pushes the filter plate 5 to reset. In this way, the filter plate 5 vibrates, thereby accelerating the feeding speed;

[0036] When a blockage occurs in the guide pipe 2, at this time, the electric push rod 4 is controlled to push the insertion rod 10 to move downward, so that the insertion rod 10 is inserted into the guide pipe 2 to extrude the material blocked in the guide pipe 2, thereby dredging the guide pipe 2.

[0037] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0038] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
