Description
Technical Field
[0001] This application relates to the field of plastic processing equipment technology, and in particular to a horizontal plastic pellet mixing device. Background Technology
[0002] Plastic granule mixing equipment is one of the key pieces of equipment in the plastic product manufacturing process. Its function is to uniformly mix different types or colors of plastic granules to meet the needs of subsequent processing.
[0003] In related technologies, plastic granule mixing devices mainly include two types: vertical and horizontal. Vertical mixing devices occupy less space but have lower mixing efficiency. Horizontal mixing devices break up material agglomerates through mechanical movement, ensuring that plastic granules of different types or states reach a homogeneous state, thereby improving the consistency quality of the finished products in subsequent processing. Compared with vertical mixing devices, they have a better mixing effect.
[0004] The existing horizontal plastic pellet processing mixing device has the following problems: the device generally discharges the material directly through the discharge port at the bottom of the mixing drum, but the plastic pellets are ejected and scattered from the edge of the discharge port due to the superposition of centrifugal force and gravity, which leads to material loss. Summary of the Invention
[0005] To reduce material loss during discharge, this application provides a horizontal plastic pellet mixing device.
[0006] The horizontal plastic granule mixing device provided in this application adopts the following technical solution:
[0007] A horizontal plastic granule mixing device includes: a frame, a mixing drum, a mixing component, a drive component, and a discharge extension component. The mixing drum and the drive component are both horizontally mounted on the frame. The mixing component is built into the mixing drum and connected to the drive component. A discharge port is provided at the bottom of the mixing drum. The discharge extension component includes an extension pipe with openings at both ends. The inlet end of the extension pipe is connected to the discharge port, and the outlet end of the extension pipe extends outward.
[0008] By adopting the above solution, the stability of the device is improved by using the frame to support the mixing drum and the drive assembly. The drive assembly drives the mixing assembly to stir the plastic granules in the mixing drum. While extending the pipeline to extend the discharge position outward, it also constrains and guides the plastic granules during the discharge process. The material flows out along the path defined by the pipeline and is collected in a centralized manner, reducing material loss caused by the ejection and splashing of plastic granules.
[0009] Preferably, the outlet end of the expansion pipe is larger than the inlet end of the expansion pipe.
[0010] By adopting the above scheme, the flow rate decreases as the cross-sectional area increases to maintain a constant flow rate. After the cross-sectional area at the outlet end is expanded, the flow rate of plastic particles in the expansion pipe is reduced, further reducing the occurrence of plastic particles splashing and ejection. The decrease in flow rate also helps to settle or separate impurities carried in the material.
[0011] Preferably, the extension pipe is installed at an angle to the ground.
[0012] By adopting the above scheme, compared with vertical pipes, the flow path of plastic granules in the expansion pipe is further extended, which prolongs the balance process between the gravitational component of the material and the frictional resistance. The gravitational potential energy of the plastic granules is converted into kinetic energy and continuously consumed by collisions with the inner wall of the expansion pipe, so that the material flows out smoothly from the outlet end of the expansion pipe.
[0013] Preferably, the inlet end of the expansion pipe is hinged to the opening of the outlet.
[0014] By adopting the above solution, workers can use hinged connections to flexibly adjust the angle of the expansion pipe and the discharge port according to the differences in the viscosity, particle size or production line layout of the plastic granules.
[0015] Preferably, it also includes vibrators, and several vibrators are provided, which are built into the inner wall of the expansion pipe and distributed at intervals along the length of the expansion pipe.
[0016] By adopting the above scheme, the vibrators distributed at intervals along the length of the expansion pipe will generate vibration together when started, which will push the plastic granules to jump or slide continuously. It can also cause the material adhering to the inner wall of the expansion pipe to separate from the inner wall due to inertia, thereby reducing material residue.
[0017] Preferably, it further includes a movable baffle, which is disposed at the outlet end of the expansion pipe. The size of the movable baffle is adapted to the size of the outlet end of the expansion pipe, and the movable baffle is hinged to the outlet end of the expansion pipe.
[0018] By adopting the above scheme, the movable baffle can rotate around the hinge as an axis, thereby opening and closing the outlet end of the expansion pipe.
[0019] Preferably, the movable baffle is further provided with a sealing strip, which is continuously provided circumferentially along the bottom edge of the movable baffle.
[0020] By adopting the above solution, the sealing strip can fill the tiny gaps in the metal contact surface through elastic deformation when the baffle is closed, thereby improving the airtightness of the expansion pipe.
[0021] Preferably, the mixing drum is provided with an arc-shaped guide plate, which is inclined from top to bottom toward the discharge port.
[0022] By adopting the above solution, the arc-shaped guide plate reduces the dead zone of right-angle accumulation of plastic particles inside the mixing drum. Under the action of gravity and centrifugal force, the plastic particles slide naturally along the arc-shaped guide plate to the discharge port, improving the discharge smoothness.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. Extending the pipeline extends the discharge point outwards, while also constraining and guiding the plastic granules during the discharge process. The material flows out along the path defined by the pipeline and is collected in a concentrated manner, reducing material loss caused by the ejection and splashing of plastic granules.
[0025] 2. Ensure that the material flows out smoothly from the outlet end of the expansion pipe;
[0026] 3. Improved equipment stability and output efficiency. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0032] This application discloses a horizontal plastic granule mixing device. (Refer to...) Figure 1 A horizontal plastic pellet mixing device includes a frame 1, a mixing drum 4, a mixing component 2, a drive component 5, and a discharge expansion component 3. The mixing drum 4 and the drive component 5 are both horizontally mounted on the frame 1. The mixing component 2 is built into the mixing drum 4 and connected to the drive component 5.
[0033] Furthermore, a discharge port 42 is provided at the bottom of the mixing drum 4. The discharge expansion assembly 3 includes an expansion pipe 31 which is provided with openings at both ends. The inlet end of the expansion pipe 31 is connected to the discharge port 42, and the outlet end of the expansion pipe 31 extends outward.
[0034] Correspondingly, the frame 1 is responsible for supporting the mixing drum 4 and the drive assembly 5, improving the stability of the device. The drive assembly 5 drives the mixing assembly 2 to uniformly mix the plastic particles in the mixing drum 4. The expansion pipe 31 forms a directional diversion channel while increasing the discharge range, enabling the material to be discharged orderly along the preset path and centrally recovered, effectively reducing the splashing and ejection of plastic particles and reducing material loss.
[0035] During the above process, referring to Figure 2-3 , the outlet end of the expansion pipe 31 is larger than the inlet end of the expansion pipe 31. According to the principle of conservation of volume flow rate in the continuity equation: Q = A1v1 = A2v2 (Q is the flow rate, A is the cross-sectional area, v is the flow velocity), when the inlet end (A1) of the expansion pipe 31 expands to the outlet end (A2), A2 > A1 ⇒ v2 < v1, and the flow velocity decreases as the cross-sectional area increases to maintain a constant flow rate.
[0036] Therefore, after the cross-sectional area of the outlet end is enlarged, the flow velocity of the plastic particles in the expansion pipe 31 is reduced, that is, the kinetic energy of the plastic particles is reduced, further reducing the occurrence of splashing and ejection of plastic particles.
[0037] Furthermore, the decrease in flow velocity prolongs the residence time of the plastic particles in the pipe, which helps to precipitate or separate the impurities carried in the material, indirectly improving the purity rate of the material.
[0038] On the other hand, the expansion pipe 31 is inclined to the ground. Compared with a vertical pipe, the plastic particles move along the inclined expansion pipe 31 under the action of gravity. The gravitational potential energy of the plastic particles is converted into kinetic energy, and the kinetic energy is continuously consumed by the continuous friction with the inner wall of the expansion pipe 31, finally making the discharge flow velocity of the material tend to be stable and flowing out smoothly from the outlet end of the expansion pipe 31.
[0039] At the same time, the extended flow path further provides time for the sedimentation of impurities in the plastic particles. Therefore, the expansion pipe 31 with an inclined structure not only improves the separation effect of the material and impurities, but also indirectly reduces the occurrence of splashing and ejection of plastic particles.
[0040] In addition, the inlet end of the expansion pipe 31 is hinged to the opening of the outlet 42, which allows for adjustment of the angle between the expansion pipe 31 and the outlet 42. This improves the convenience and flexibility of the device. Operators can change the angle between the expansion pipe 31 and the outlet 42 according to the differences in the viscosity, particle size or production line layout of the plastic granules, so as to adapt to the flow characteristics of different materials and thus obtain better discharge effect.
[0041] Furthermore, the rotational degree of freedom at the hinge changes the load transmission path of the traditional rigid connection. When the vibration generated by the operation of the equipment and the scouring of materials acts on the hinge, the energy is released along the sliding direction of the hinge, reducing the occurrence of stress concentration.
[0042] On the other hand, the discharge expansion component 3 also includes a vibrator 3434. In this embodiment, several vibrators 34 are provided. The vibrators 34 are miniature vibration motors. The vibrators 34 are distributed at intervals along the length of the expansion pipe 31.
[0043] Correspondingly, when the vibrator 34 is working, all the vibrators 34 vibrate at the same frequency, which makes the inertia of the plastic particles on the inner wall of the expansion pipe 31 greater than the adhesion force it is subjected to. The plastic particles are peeled off and pushed to jump or slide continuously, which improves the discharge efficiency and reduces material residue.
[0044] On the other hand, the discharge expansion assembly 3 also includes a movable baffle 32. The size of the movable baffle 32 matches the size of the opening end of the expansion pipe 31. When the movable baffle 32 is closed, it can completely seal the outlet end of the expansion pipe 31, thereby stopping the equipment from discharging.
[0045] Furthermore, the movable baffle 32 is hinged to the outlet end of the expansion pipe 31, allowing the operator to rotate the movable baffle 32 circumferentially around the hinge as an axis, thus manually opening and closing the material channel quickly.
[0046] Meanwhile, an annular sealing strip 33 is also fixed on the movable baffle 32. The sealing strip 33 is continuously arranged circumferentially along the bottom edge of the movable baffle 32. When the baffle performs the closing action, the sealing strip 33 is squeezed and generates elastic deformation, and automatically compensates for the small gaps in the metal contact surface, thereby improving the airtightness of the expansion pipe 31.
[0047] In addition, in this embodiment, two arc-shaped guide plates 43 are symmetrically arranged inside the mixing drum 4 with the discharge port 42 as the center. One end of each arc-shaped guide plate 43 is fixed to the frame, and the other end of each arc-shaped guide plate 43 is inclined from top to bottom towards the discharge port 43.
[0048] Correspondingly, the arc-shaped guide plate 43 reduces the dead zone of right-angle accumulation of plastic particles inside the mixing drum 4. Under the action of gravity and centrifugal force, the plastic particles slide naturally along the arc-shaped guide plate 43 to the discharge port 42, thereby optimizing the discharge direction of the material inside the mixing drum 4 and improving the smoothness of discharge.
[0049] In the process described above, the stirring assembly 2 includes a rotating shaft 21 and several stirring blades 22. The rotating shaft 21 is horizontally arranged inside the stirring drum 4. Both ends of the rotating shaft 21 pass through both ends of the stirring drum 4 and are fixed to the frame 1. Several stirring blades 22 are distributed at intervals along the length of the rotating shaft 21 and fixed to the side wall of the rotating shaft 21.
[0050] Furthermore, the drive assembly 5 includes a motor 51 and a gearbox 52. Both the motor 51 and the gearbox 52 are mounted on the frame 1. One end of the gearbox 52 is rotatably connected to the output shaft of the motor 51 via a transmission belt, and the other end of the gearbox 52 is rotatably connected to the rotating shaft 21 via a coupling.
[0051] Meanwhile, the mixing drum 4 is set in a semi-cylindrical structure. The top of the mixing drum 4 is hinged with a drum cover 41 that matches the cross-sectional size of the mixing drum 4. The operator can manually lift the drum cover 41, manually feed materials from the top of the mixing drum 4, and then close it.
[0052] Furthermore, a control panel is also installed on the frame 1. The operator can adjust the speed of the motor 51 and the mixing time through the control panel. The motor 51 drives the rotating shaft 21 to rotate the stirring blade 22 in the circumferential direction. The stirring blade 22 effectively breaks up the adhesion and clumping of plastic particles through the shear force field generated by the high-speed rotation. At the same time, it guides the material to move synchronously in the axial and radial directions to form convective mixing. After the plastic particles are evenly mixed, the operator opens the movable baffle 32, so that the material slides along the arc-shaped guide plate 43 to the discharge port 42 and flows out from the opening of the expansion pipe 31.
[0053] Correspondingly, this is a conventional technical method for conventional equipment in this field, and will not be elaborated on further here.
[0054] The implementation principle of the horizontal plastic granule mixing device in this application embodiment is as follows: the expansion pipe 31 increases the discharge range and forms a directional flow channel, so that the plastic granules flow out smoothly along the expansion pipe 31 and are collected in a concentrated manner. In conjunction with the vibrator 34 on the inner wall of the expansion pipe 31, the material is vibrated and fed, which effectively reduces the adhesion and residue of plastic granules and the occurrence of splashing and ejection, thereby reducing material loss.
[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
