Description

Technical Field

[0001] This utility model relates to the field of plastic particle cleaning, and more specifically, it relates to a surface cleaning device for plastic particles. Background Technology

[0002] In the industrial production process of plastic granules, the cleanliness of the raw material pretreatment stage directly affects the product quality of subsequent key processes such as extrusion molding and injection molding. Therefore, it is crucial to clean and treat impurities such as dust, metal shavings, oil stains and mold release agent residues adhering to the surface of plastic granules.

[0003] Existing surface cleaning equipment generally uses a cylindrical container with an open top as the cleaning tank, with a brush roller as the core cleaning component inside. The mechanical friction of the brush roller removes impurities from the particle surface. However, the traditional technical solution has significant drawbacks: its drive system requires two independent motors, one to control the revolution of the brush roller around the central axis of the cleaning tank and the other to control its own rotation (the revolution is to increase the cleaning range of the brush roller, and the rotation allows the bristles on the surface of the brush roller to contact the particle surface at different angles and directions, enabling more thorough scraping, loosening, and removal of stubbornly attached impurities). This dual-motor drive mode not only increases the equipment manufacturing cost by 30% to 40%, but the additional energy consumption also reduces the economic efficiency of production.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a surface cleaning device for plastic particles. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a surface cleaning device for plastic particles.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a surface cleaning device for plastic granules, comprising a cleaning tank for cleaning plastic granules, the cleaning tank being a cylindrical container with an open top, a motor A installed directly above the cleaning tank, a brush roller installed inside the cleaning tank, and a transmission structure installed on the cleaning tank, which drives the brush roller to rotate around the inside of the cleaning tank while also rotating on its own axis via a motor A.

[0007] Preferably, a support frame for supporting motor A is installed on the side end of the cleaning tub.

[0008] Preferably, the transmission structure includes an annular toothed plate fixed to the inner side wall of the cleaning tub near the opening, the transmission shaft of the motor A is fixed to the bearing A via a connecting plate, a rotating rod is fixedly connected to the inner ring of the bearing A, and a gear that meshes with the annular toothed plate is fixedly connected to the bottom of the rotating rod, and the brush roller is installed at the bottom of the gear.

[0009] Preferably, a cast iron counterweight base is installed at the bottom of the cleaning tub.

[0010] Preferably, the motor A is powered by a battery, and a drive assembly is installed inside the cast iron counterweight base to drive the rotation of the cleaning tub.

[0011] Preferably, the cast iron counterweight base has an internal cavity, the drive assembly includes a motor B installed in the cavity, a bearing B is embedded and fixed at the top of the cast iron counterweight base, a rotating column is fixedly connected to the inner ring of the bearing B, and the bottom end of the rotating column extends into the cavity and is connected to the drive shaft of the motor B, and its top end is connected to the center of the bottom of the cleaning tub.

[0012] Preferably, both the support frame and the annular toothed plate are detachably connected to the cleaning tub by screws.

[0013] Preferably, the cast iron counterweight base has an internal cavity, the drive assembly includes a motor B installed in the cavity, a bearing B is embedded and fixed at the top of the cast iron counterweight base, a rotating column is fixedly connected to the inner ring of the bearing B, and the bottom end of the rotating column extends into the cavity and is connected to the drive shaft of the motor B, and its top end is connected to the center of the bottom of the cleaning tub.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention uses a single motor A to drive a transmission structure to simultaneously achieve the revolution and rotation of the brush roller, changing the traditional mode of dual motors controlling the two movements separately. While ensuring the surface cleaning effect, it reduces manufacturing costs and energy consumption, thus solving the problems in the background technology.

[0016] The support frame and the annular toothed plate of this utility model are detachably connected to the cleaning tank by screws. In this way, when the motor A and the transmission structure are damaged, the screws can be quickly removed for individual replacement without affecting the use of the cleaning tank and avoiding the impact on cleaning efficiency due to maintenance.

[0017] This invention utilizes the rotation of the cleaning tub to generate centrifugal force and tumbling motion of the internal plastic particles along the tub wall. Combined with the revolution and rotation of the brush roller, this creates multi-directional and multi-dimensional mechanical friction, ensuring that all areas of the particle surface can fully contact the brush bristles, significantly enhancing the uniformity and thoroughness of impurity removal.

Detailed Implementation

[0025] like Figure 1-5 As shown, this utility model provides a surface cleaning device for plastic granules, including a cleaning tank 1 for cleaning plastic granules. The cleaning tank 1 is a cylindrical container with an open top. A motor A2 is installed directly above the cleaning tank 1. A brush roller 3 is installed inside the cleaning tank 1. A transmission structure 5 is also installed on the cleaning tank 1, which drives the brush roller 3 to rotate around the inside of the cleaning tank 1 while rotating on its own axis. A support frame 6 is installed on the side of the cleaning tank 1 to support the motor A2.

[0026] In use, the cleaning solution and plastic granules are first placed into the cleaning tank 1. Then, the motor A2 is started, and the power is transmitted to the brush roller 3 inside the cleaning tank 1 through the transmission structure 5. This causes the brush roller 3 to revolve around the central axis of the cleaning tank 1 while simultaneously rotating on its own axis. Since the cleaning tank 1 is a cylindrical container with an open top, the plastic granules to be cleaned are placed inside. During its revolution, the brush roller 3 rotates along the internal space of the cleaning tank 1, covering different areas inside the tank. The rotation causes the bristles on the surface of the brush roller 3 to continuously generate mechanical friction with the plastic granules, thereby achieving the removal and cleaning of impurities from the surface of the plastic granules. This method, which uses a single motor A2 to drive the transmission structure 5 to simultaneously achieve the revolution and rotation of the brush roller 3, changes the traditional mode of using two motors to control the two movements separately. This reduces manufacturing costs and energy consumption while ensuring the surface cleaning effect.

[0027] This utility model also provides a specific transmission structure 5: the transmission structure 5 includes an annular toothed plate 501 fixed on the inner side wall of the cleaning tub 1 near the opening, the transmission shaft of the motor A2 is fixed to the bearing A503 through the connecting plate 502, a rotating rod 504 is fixedly connected in the inner ring of the bearing A503, and a gear 505 that meshes with the annular toothed plate 501 is fixedly connected to the bottom of the rotating rod 504, and the brush roller 3 is installed at the bottom of the gear 505.

[0028] When motor A2 starts, its drive shaft drives the outer ring of bearing A503, which is fixed to it via connecting plate 502, to rotate. Since the inner ring of bearing A503 is fixedly connected to rotating rod 504, and the gear 505 at the bottom of rotating rod 504 meshes with annular toothed plate 501 fixed on the inner side wall of cleaning tank 1, during the process of bearing A's outer ring revolving around the drive shaft of motor A (which also drives the brush roller 3 to revolve, causing the brush roller 3 to rotate along the internal space of cleaning tank 1), gear 505 will roll along annular toothed plate 501, thus being driven to rotate, thereby driving rotating rod 504 to rotate around its own axis. At this time, the inner ring of bearing A503 rotates along its outer ring. Since brush roller 3 is installed at the bottom of gear 505, brush roller 3 will move synchronously with the revolution and rotation of gear 505, realizing a compound motion of both revolving around the central axis of cleaning tank 1 and rotating around its own axis, thereby thoroughly cleaning the plastic particles in cleaning tank 1.

[0029] Furthermore, both the support frame 6 and the annular toothed plate 501 are detachably connected to the cleaning tank 1 by screws. This allows for quick removal of the screws for individual replacement in case of damage to the motor A2 and the transmission structure 5, without affecting the use of the cleaning tank 1 and avoiding impact on cleaning efficiency due to maintenance.

[0030] The bottom of the cleaning tub 1 is equipped with a cast iron counterweight base 7. The cast iron counterweight base 7 is made of cast iron material, which has a high density and is heavier than ordinary materials for the same volume, so it can stably support the cleaning tub 1.

[0031] Furthermore, motor A2 is powered by a battery (to prevent the motor A2 wires from getting tangled when the cleaning tub 1 rotates), and the cast iron counterweight base 7 has a drive assembly 4 installed inside to drive the rotation of the cleaning tub 1.

[0032] The rotation of the cleaning tub 1 causes the internal plastic particles to generate centrifugal force and tumbling motion along the tub wall. Combined with the revolution and rotation of the brush roller 3, this creates multi-directional and multi-dimensional mechanical friction, ensuring that all areas of the particle surface (including the bottom, edges, and recesses) can fully contact the brush bristles. This significantly enhances the uniformity and thoroughness of impurity removal. The design of the motor A2 being battery-powered and the drive assembly 4 integrated into the cast iron counterweight base 7 combines practicality and safety: Firstly, battery power frees the motor A from the constraints of traditional power cords, completely avoiding the risk of wire tangling, pulling, or even short circuits caused by the rotation of the cleaning tub 1, thus improving the reliability and safety of the equipment. Secondly, the drive assembly 4, built into the cast iron counterweight base 7, utilizes the high density of cast iron to lower the center of gravity of the equipment, enhancing overall stability and reducing vibration and noise during operation. Simultaneously, hiding the drive component of the drive assembly 4 (referring to motor B401) inside the base saves external space and effectively protects the drive assembly 4 from corrosion by sewage and particles during the cleaning process, extending the equipment's service life.

[0033] The following is the specific structure of the drive assembly 4: The cast iron counterweight base 7 has a cavity 701 inside. The drive assembly 4 includes a motor B401 installed in the cavity 701. A bearing B402 is embedded and fixed on the top of the cast iron counterweight base 7. A rotating column 403 is fixedly connected in the inner ring of the bearing B402. The bottom end of the rotating column 403 extends into the cavity 701 and is connected to the drive shaft of the motor B401. Its top end is connected to the center of the bottom end of the cleaning tub 1.

[0034] In use, the motor B401 drives the rotation of the rotating column 403, which in turn drives the inner ring of the bearing B402 to rotate. The inner ring rotates along with the outer ring, thus providing rotational support for the rotating column 403. The rotating column 403 drives the cleaning tub 1 to rotate, thereby rotating the cleaning tub 1.

[0035] The top of the cast iron counterweight base 7 is provided with an annular groove 8. A slider 9, which slides around the annular groove 8, is slidably connected inside the annular groove 8. The top of the slider 9 is connected to the bottom of the cleaning tub 1 via a vertical rod 10. That is, when the cleaning tub 1 rotates, the cleaning tub 1 will drive the slider 9 to rotate via the vertical rod 10. The slider 9 slides along the inside of the annular groove 8. The design of the annular groove 8 and the slider 9, by constructing a multi-point support system, significantly optimizes the rotational stability of the cleaning tub 1: On the one hand, when the motor B401 drives the rotating column 403 to rotate the cleaning tub 1, the slider 9, which is evenly distributed within the annular groove 8... Block 9 is connected to the bottom of the tank via vertical rod 10, forming a ring support network around rotating column 403. This effectively disperses the gravitational load of the cleaning tank 1 and its internal materials, reduces the stress on rotating column 403 as a single support point, and lowers the risk of bending stress and wear caused by off-center loading. On the other hand, the sliding engagement of slider 9 in the annular groove 8 provides auxiliary guidance for the rotation of the cleaning tank 1, ensuring the accuracy of the rotation trajectory. It also absorbs the radial vibration generated during rotation through sliding friction. Combined with the center-of-gravity stabilization effect of cast iron counterweight base 7, it significantly reduces the shaking and noise during equipment operation.
