Abstract
Description
Technical Field
[0001] This utility model relates to the field of modified plastic material mixing technology, and in particular to a mixing device for the production of modified plastic materials. Background Technology
[0002] Modified plastics refer to plastic products that have been modified by methods such as filling, blending, and reinforcement based on general-purpose plastics and engineering plastics, thereby improving their properties such as flame retardancy, strength, impact resistance, and toughness.
[0003] An existing mixing device for the production of modified plastic materials, with announcement number CN216879088U, has a housing connected to a mixing plate via a mounting frame. During use, the material enters the interior of the mounting frame through the feed pipe and falls onto the first set of mixing plates. At this point, the motor can be directly turned on to drive the eccentric vibrator, causing the mixing plate to vibrate and mix the material inside under the action of the vibration force. After mixing to a certain extent, the material will effectively enter the second set of mixing plates through the groove, where it will vibrate and mix again. After mixing to a certain extent again, the material can fall directly into the interior of the housing through the groove and be stirred and mixed by the stirring shaft.
[0004] Because the groove is not equipped with a specific opening and closing mechanism, after the material enters the device, some of the material will flow directly from the groove to the next area, resulting in a short residence time in the current mixing area. This makes it difficult to guarantee the uniformity of a single mixing and reduces the mixing effect of the device. Utility Model Content
[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a mixing device for the production of modified plastic materials.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mixing device for the production of modified plastic materials, comprising a housing, a feeding box rotatably connected to the top of the housing, a partition plate fixedly connected inside the feeding box passing through the central axis of the feeding box, the partition plate dividing the inner cavity of the feeding box into two independent material bins, each material bin having a row of feeding ports at its bottom, a guide pipe array connected below the feeding ports, one row of feeding ports connected to one guide pipe, a transmission mechanism provided inside the housing, the transmission mechanism including a mounting plate fixedly connected to the inner side wall of the housing and a driving wheel and a driven wheel driven by a belt strip, the bottom of the driving wheel being rotatably connected to the mounting plate.
[0007] Preferably, the top of the drive wheel meshes with a gear ring at the bottom of the discharge box via a gear pair, a stirring rod is rotatably connected inside the housing, and the driven wheel is fixedly connected to the main shaft of the stirring rod.
[0008] Preferably, the bottom of the feeding box extends outward and into the interior of the housing, and the toothed ring is fixedly connected to the extended end of the bottom of the feeding box.
[0009] Preferably, a support frame is fixedly connected to the outer side of the housing, and a motor is fixedly connected to the middle of the support frame. The main shaft of the motor is collinear with the central axis of the feeding box, and the main shaft of the motor is fixedly connected to the partition.

[0011] Preferably, a shield for protecting the driving wheel and the driven wheel is fixedly connected inside the housing.
[0012] Preferably, the guide tube is provided with a spiral blade.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, by setting up a feeding box, a guide pipe and a spiral blade, different materials are first stored separately in the independent hopper of the feeding box, and then enter the same guide pipe through the feed inlet. In the guide pipe, the spiral blade lengthens the flow path and promotes mixing, thus achieving preliminary mixing. The rotation of the feeding box causes the material to fall into the shell in a spiral shape, increasing the contact area of different materials and improving the preliminary mixing effect.

In this utility model, by setting a motor to drive the material feeding box to rotate, and using a transmission mechanism composed of a toothed ring at the bottom of the material feeding box, a driving wheel, a driven wheel and a belt to drive the stirring rod to rotate, the linkage between material feeding and stirring is realized, reducing the use of an additional power source and simplifying the equipment structure.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] 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. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] like Figure 1-5 As shown, a mixing device for producing modified plastic materials includes a housing 1. A feeding box 2 is rotatably connected to the top of the housing 1. A partition 7 passing through the central axis of the feeding box 2 is fixedly connected inside the feeding box 2, dividing the inner cavity of the feeding box 2 into two independent hoppers 16. Each hopper 16 has a row of feeding ports 6 at its bottom. An array of guide pipes 8 is connected below the feeding ports 6, with one row of feeding ports 6 connected to one guide pipe 8. A transmission mechanism is provided inside the housing 1, and the transmission mechanism includes components connected to the housing. The inner wall of the housing 1 is fixedly connected to the mounting plate 15 and the drive wheel 11 and driven wheel 12 driven by the belt. The bottom of the drive wheel 11 is rotatably connected to the mounting plate 15. The top of the drive wheel 11 is engaged with the gear ring 10 at the bottom of the discharge box 2 through a gear pair. The housing 1 is rotatably connected to the stirring rod 13. The driven wheel 12 is fixedly connected to the main shaft of the stirring rod 13. The bottom of the discharge box 2 extends outward and into the housing 1. The gear ring 10 is fixedly connected to the extended end at the bottom of the discharge box 2.
[0025] In this technical solution, a discharge box 2 is set up to place materials inside. Two independent hoppers 16 are used to hold different materials. Through the inlet 6, different materials are driven into the same guide pipe 8 and then fall into the shell 1 for mixing. Furthermore, by setting up the guide pipe 8, two different materials enter the same guide pipe 8 through the inlet 6 in their respective hoppers 16. During the flow in the guide pipe 8, preliminary mixing can be carried out, improving the preliminary mixing efficiency. In addition, by setting up a rotatable connection between the discharge box 2 and the shell 1, the discharge box 2 rotates relative to the shell 1 during operation. The materials flowing out from the guide pipe 8 fall into the shell 1 in a spiral shape, increasing the contact area between different materials and further improving the preliminary mixing efficiency.
[0026] The specific transmission method is as follows: the rotation of the feeding box 2 drives the gear ring 10 to rotate, the rotation of the gear ring 10 drives the gear pair on the drive wheel 11 to rotate, thereby driving the drive wheel 11 to rotate, which in turn drives the driven wheel 12 to rotate via the belt, thereby driving the stirring rod 13 to rotate, and the rotation of the stirring rod 13 further stirs and mixes the material.
[0027] like Figure 3 As shown, a support frame 3 is fixedly connected to the outer side of the housing 1, and a motor 4 is fixedly connected to the middle of the support frame 3. The main shaft of the motor 4 is coaxial with the central shaft of the feeding box 2, and the main shaft of the motor 4 is fixedly connected to the partition plate 7.
[0028] In this technical solution, a motor 4 is set up, and the rotation of the main shaft of the motor 4 drives the partition 7 to rotate, which in turn drives the feeding box 2 to rotate.
[0029] like Figure 1 As shown, the bottom surface of the inner cavity of the feeding box 2 is provided with a slope 5 that is inclined towards the feeding port 6.
[0030] In this technical solution, by setting up a slope 5, the material in the silo 16 can be easily flowed into the inlet 6.
[0031] like Figure 3 As shown, a shield 14 for protecting the driving wheel 11 and the driven wheel 12 is fixedly connected inside the housing 1.
[0032] In this technical solution, by setting up a baffle 14, the material flowing out of the guide pipe 8 is prevented from falling onto the meshing points of the drive wheel 11 and driven wheel 12 with the belt, as well as the meshing points of the gear pair and the gear ring 10, thereby preventing damage to the transmission mechanism.
[0033] like Figure 5 As shown, a spiral blade 9 is installed inside the guide tube 8.
[0034] In this technical solution, by setting the spiral blade 9, when the material flows in the guide pipe 8, the spiral blade 9 lengthens the flow path and promotes the mixing of different materials in the guide pipe 8, thereby improving the initial mixing effect.
[0035] Working principle: During operation, different materials are placed in two hoppers 16. The motor 4 is started, and the main shaft of the motor 4 rotates, which drives the partition 7 to rotate, and in turn drives the discharge box 2 to rotate around its central axis. The material falls into the shell 1 in a spiral shape after passing through the feed port 6 and the guide pipe 8. When the discharge box 2 rotates, the gear ring 10 rotates accordingly. The gear ring 10 drives the gear pair on the drive wheel 11 to rotate, which in turn drives the drive wheel 11 to rotate. The drive wheel 11 drives the driven wheel 12 to rotate through the belt strip. The driven wheel 12 drives the stirring rod 13 to rotate, further stirring the material falling into the shell 1.
[0036] The wiring diagram of motor 4 in this utility model is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of motor 4 will not be explained in detail.
[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
