Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mixing devices, in particular to a mixing device used for mixing plastics. Background Art
[0002] Plastics are polymer compounds that are polymerized from monomers through addition polymerization or condensation polymerization. They have a medium deformation resistance, between fiber and rubber. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. The main component of plastics is resin. Resin refers to a polymer compound that has not been mixed with various additives. In order to improve the overall performance of the plastic itself during the production process, various auxiliary materials such as fillers, plasticizers, lubricants, stabilizers, and colorants are added to the polymer. Therefore, a mixing device is needed to mix the materials during the production of plastics.
[0003] The mixing devices used in the prior art still have defects. Among them, during the use, the plastic can only be stirred and mixed in one aspect, and the effective mixing of the materials cannot be guaranteed. If the materials are simply stirred during stirring, and cannot be vibrated during stirring, the mixing will not be sufficient during stirring, and more materials will be attached to the inner wall of the mixing box, and the materials attached to the inner wall cannot be mixed with the materials not attached to the inner wall, resulting in uneven mixing of the materials. At the same time, when discharging the materials, the materials cannot be completely discharged during the discharging process because the materials are attached to the inner wall. Therefore, there is an urgent need for a mixing device for plastic mixing with a vibrating effect. Utility Model Content

DETAILED DESCRIPTION
[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.
[0019] Please refer to Figure 1-Figure 5 As shown, the utility model provides a mixing device for mixing plastics, including a mixing barrel 1, a rotating rod 12 is rotatably arranged at the axis of the inner wall of the mixing barrel 1, a limiting ring 2 with an annular structure is sleeved on the outer periphery of the rotating rod 12, and a stirring connecting rod 21 for stirring materials is fixedly arranged between the limiting ring 2 and the rotating rod 12.
[0020] A fixing block 4 is fixedly connected to the inner wall of the mixing cylinder 1 , a first elastic knocking mechanism is telescopically arranged in the fixing block 4 on one side facing the limiting ring 2 , and a limiting guide plate 14 is fixedly arranged on one side of the fixing block 4 .
[0021] A connecting block 3 is fixedly connected to the horizontal plane of the limiting ring 2 corresponding to the first elastic knocking mechanism. A second elastic knocking mechanism for elastically knocking the first elastic knocking mechanism is telescopically arranged in the connecting block 3 . The second elastic knocking mechanism elastically contacts the limiting guide plate 14 .
[0022] The distance between the limiting guide plate 14 and the second elastic knocking mechanism is greater than the distance between the first elastic knocking mechanism and the second elastic knocking mechanism.
[0023] In the present case, by introducing the material for producing plastic into the mixing barrel 1, the rotating rod 12 can drive the stirring connecting rod 21 to rotate, the stirring connecting rod 21 drives the limiting ring 2 to rotate, and the limiting ring 2 drives the connecting block 3 to rotate, so that the second elastic knocking mechanism can rotate in the mixing barrel 1.
[0024] Among them, a fixed block 4 is fixedly arranged in the mixing barrel 1, and a first elastic knocking mechanism that is elastically retractable is arranged in the fixed block 4, and a limiting guide plate 14 is fixedly arranged on one side of the fixed block 4. The second elastic knocking mechanism first passes through the limiting guide plate 14 during the rotation process. Under the action of the limiting guide plate 14, the second elastic knocking mechanism can be contracted to be in a compressed state. Due to the existence of elasticity, the elasticity will be released at the moment when the second elastic knocking mechanism slides over the limiting guide plate 14. At this time, the second elastic knocking mechanism extends out and moves toward the fixed block 4, and the second elastic knocking mechanism corresponds to the first elastic knocking mechanism arranged in the fixed block 4, so that the second elastic knocking mechanism can knock And press the first elastic knocking mechanism, so that the first elastic knocking mechanism contracts and knocks on the fixed block 4. At the moment after the knocking, the first elastic knocking mechanism releases its elasticity and rebounds the second elastic knocking mechanism again. Under the condition of bidirectional force, it can knock on both the fixed block 4 and the connecting block 3. Under the condition of the knocking force, the mixing cylinder 1 and the limiting ring 2 can be in a vibrating state. In the vibrating state, the materials attached to the inner wall of the mixing cylinder 1 and the outer periphery of the limiting ring 2 can be shaken down. During the stirring process, the mixing cylinder 1 is shaken to cause it to vibrate. Under the action of the vibration force, the materials attached to the inner wall of the mixing cylinder 1 can be effectively shaken off, so that the materials can be fully mixed.
[0025] Among them, through the rotation of the limit ring 2, the material can be stirred through the stirring connecting rod 21, and the material attached to the inner wall of the mixing barrel 1 can be shaken off under the coordinated knocking of the first elastic knocking mechanism and the second elastic knocking mechanism, so as to avoid the material from sticking to the inner wall of the mixing barrel 1, thereby ensuring sufficient mixing between the materials during the stirring process, and the shock force generated by the knocking during discharge can also ensure that all the mixed materials are discharged, thereby avoiding waste of materials, and at the same time avoiding affecting the reuse of the mixing device, thereby improving the use efficiency.
[0026] Among them, the distance between the limiting guide plate 14 and the second elastic knocking mechanism is greater than the distance between the first elastic knocking mechanism and the second elastic knocking mechanism. When the second elastic knocking mechanism passes through the limiting guide plate 14, the second elastic knocking mechanism is in a compressed state, and the elasticity can be released instantly after passing through to press the first elastic knocking mechanism.
[0027] The fixing blocks 4 are arranged in multiple groups and are arranged at equal distances along the circumference of the inner wall of the mixing cylinder 1 .
[0028] By arranging multiple groups of fixing blocks 4, the force of knocking can be increased during stirring. Under the multi-directional knocking, the vibration effect of the mixing barrel 1 is improved, so that the material can be shaken off the inner wall of the mixing barrel 1 to ensure the mixing uniformity between the materials.
[0029] The first elastic knocking mechanism includes a first shock block 13, a second slider 41, a second spring 411, a second limiting rod 42 and a second shock block 421. A limiting groove for the second slider 41 to slide is opened on one side of the fixed block 4. The second spring 411 is fixedly arranged between the second slider 41 and the bottom of the limiting groove. The second limiting rod 42 is inserted in the second spring 411, and one end of the second limiting rod 42 is fixedly connected to the second slider 41, and the other end of the second limiting rod 42 is fixedly connected to the second shock block 421. The first shock block 13 and the second shock block 421 are arranged correspondingly, and the first shock block 13 is fixedly arranged at the bottom of the limiting groove.
[0030] The sliding of the second slider 41 can drive the second limiting rod 42 to move, and the second limiting rod 42 presses the second spring 411, and can drive the second shock block 421 to slide in the limiting groove. During the sliding process of the second shock block 421, it can hit the first shock block 13. At the moment of collision between the first shock block 13 and the second shock block 421, a shock force will be generated at the same time, and vibration can be generated under the action of the shock force, so that the mixing barrel 1 can vibrate.
[0031] The second elastic knocking mechanism includes a first spring 31, a first slider 32, a first limiting rod 33 and a knocking ball 331. A sliding groove for the first slider 32 to slide is opened in the connecting block 3. The first spring 31 is fixedly arranged between the first slider 32 and the bottom of the sliding groove. One end of the first limiting rod 33 is fixedly connected to the first slider 32. The other end of the first limiting rod 33 passes through the connecting block 3 and is fixedly connected to the knocking ball 331. The end of the knocking ball 331 is connected to the second slider 41 by knocking and contacting, and the end of the knocking ball 331 is connected to the limiting guide plate 14 by sliding and contacting.
[0032] Through the rotation of the limiting ring 2, the knocking ball 331 is driven to rotate. When the knocking ball 331 passes through the limiting guide plate 14, the knocking ball 331 is pressed, and the knocking ball 331 contracts and presses the first spring 31. After the knocking ball 331 passes through the limiting guide plate 14, the resistance force is instantly lost. At this time, the first spring 31 instantly releases the elastic force, so that the knocking ball 331 presses and knocks the second slider 41. At the moment of knocking, the second slider 41 can press the second spring 411, and the second shock block 421 knocks the first shock block 13. At the moment after knocking, the second slider 41 rebounds under the action of the second spring 411, and the second slider 41 rebounds and presses the knocking ball 331, so that the limiting ring 2 is in a vibrating state, so that the material attached to the mixing barrel 1 can be shaken off, thereby improving the mixing efficiency of the material.
[0033] The top surface of the limiting guide plate 14 is arranged in an arc-shaped structure.
[0034] The arc-shaped top surface of the limiting guide plate 14 can prevent materials from being pushed and accumulated on the top surface of the limiting guide plate 14 .
[0035] Among them, the top surface of the fixing block 4, the top surface of the connecting block 3 and the top surface of the limiting ring 2 are all arranged in an arc-shaped structure to avoid the accumulation of materials.
[0036] A feed port is provided on the top surface of the mixing drum 1 to facilitate the material to be led out of the mixing drum 1 , and a discharge port is provided on the bottom surface of the mixing drum 1 to facilitate the fully and evenly mixed material to be discharged for use.
[0037] Among them, a buffer support rod 11 is arranged on the bottom surface of the mixing cylinder 1. The structure of the buffer support rod 11 is a mature technology in the prior art and belongs to the well-known technology of buffer support. It is not described in detail in the present utility model. Through the action of the buffer support rod 11, the mixing cylinder 1 is in a vibrating state.
[0038] The above are only embodiments of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the technical solution of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
