Description

Technical Field

[0001] This utility model belongs to the field of plastic product testing technology, specifically relating to an automatic filling device. Background Technology

[0002] The main raw material for plastic products is resin, a high molecular weight compound also known as plastic or synthetic resin. The manufacturing process of plastic products mainly involves two steps: first, synthesizing active semi-finished products (monomers), and then linking thousands of monomers into macromolecules (polymers). Secondly, plastic products require the addition of other additives, including heat stabilizers, antioxidants, plasticizers, flame retardants, and other additives, to improve the quality of the plastic products. The raw materials for plastic products are usually mixed with additives before being injected into plastic processing equipment. There are several methods for adding additives to plastic product batches, including direct addition, pre-dispersion addition, masterbatch addition, and compression addition. Among these, the pre-dispersion addition method involves mixing the additives with a certain dispersant beforehand to form uniform granular substances, which are then added to the plastic processing machine for processing. This method, through pretreatment, can fully disperse the additives, improving the addition effect, and is especially suitable for situations with large addition amounts.

[0003] When studying the quality and material properties of plastic products, the pre-dispersion addition method involves mixing raw materials and additives, then transporting the mixture to the feed inlet of a plastic processing machine for addition to prepare test samples. However, this method not only increases the workload of operators (including mixing, stirring, and transporting the additives), but may also lead to uneven dispersion of the additives, thereby reducing the test results. Utility Model Content

[0004] The purpose of this invention is to provide an automatic filling device that can solve the above-mentioned technical problems.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] The present invention provides an automatic filling device, including a filling frame, a discharge plate and a mixing assembly. An installation frame is installed on the lower side of the outer wall of the filling frame for fixing the filling frame at the inlet position on the plastic processing machine. The mixing assembly is disposed inside the filling frame. A drive motor is installed on the side of the filling frame for driving the mixing assembly to rotate.

[0007] Two symmetrical arc-shaped blocks are installed on opposite sides of the lower part of the packing frame. The unloading plate is slidably installed in the packing frame and one of the arc-shaped blocks. The opposite sides of the two arc-shaped blocks are formed with symmetrical arc-shaped surfaces. The lower side of the other arc-shaped block is formed with an inner groove for overlapping the parallel sliding unloading plate. Electric push rods are installed on opposite sides of the outer wall of the packing frame. A linkage plate is provided on the outer side of the packing frame. The extended end of the electric push rod is installed on the side of the linkage plate. The linkage plate is installed on the side of the unloading plate.

[0008] Using the aforementioned automatic filling device, raw materials and additives are added one by one into the filling frame. Then, the drive motor is started by a switch. The drive motor drives the stabilizing shaft on the mixing assembly to rotate. The stabilizing shaft drives the pulley group and the main shaft, which in turn drives the rotating plate and the mixing plate to mix the raw materials and additives in the filling frame. At the same time, the main gear on the stabilizing shaft meshes, driving the driven gear to rotate. The driven gear drives the rotating sleeve and the drive plate to rotate in the opposite direction. Simultaneously, the two side scrapers rotate in the opposite direction to the mixing plate, thereby tumbling and mixing the raw materials and additives. This ensures that the raw materials and additives in the filling frame are thoroughly mixed. Then, the electric push rod is extended by a switch. The electric push rod drives the linkage plate and the discharge plate to slide, thereby opening the discharge channel and allowing the mixed raw materials to fall into the plastic processing machine for processing.

[0009] Preferably, the mixing assembly includes a main shaft, a rotating sleeve, a drive plate, and rotating plates. The rotating sleeve is rotatably mounted on one side plate of the packing frame. One side of the main shaft is rotatably mounted inside the rotating sleeve, and the other side is rotatably mounted on another side plate of the packing frame. There are two rotating plates, which are arranged inside the packing frame. The two rotating plates are fixedly mounted on the main shaft, and two sets of mixing plates symmetrical about the main shaft are installed on the opposite sides of the two rotating plates.

[0010] Preferably, a drive plate and a stabilizing plate are provided on opposite sides of the two rotating plates. Both the drive plate and the stabilizing plate are located inside the packing frame. The drive plate is fixedly mounted on the rotating sleeve, and the stabilizing plate is rotatably mounted on the side of the main shaft away from the rotating sleeve. Two side scrapers are provided inside the packing frame. The two side scrapers are located on opposite sides of the two sets of mixing and stirring plates. The two side scrapers are fixedly mounted on opposite sides of the drive plate and the stabilizing plate, respectively.

[0011] Preferably, the side of the packing frame is provided with a main gear and a driven gear, and a stabilizing shaft is rotatably mounted on the side of the packing frame via a bearing seat. The main gear is mounted on the stabilizing shaft, the driven gear is mounted on a rotating sleeve, and a pulley set is mounted on the side of the packing frame. The pulley set connects the main shaft and the stabilizing shaft, and the output shaft of the drive motor is mounted on the free end of the stabilizing shaft.

[0012] Preferably, each set of mixing plates includes two plates, which are arranged symmetrically. The mixing plates are tilted at 30° relative to the plane of the rotating plate.

[0013] Preferably, the side scraper is set at an angle of 45° with the plane of the stabilizing plate or the driving plate as a reference.

[0014] The beneficial effects are:

[0015] This invention utilizes a packing frame and a mixing assembly to ensure thorough mixing of the plastic raw materials and additives within the packing frame, thereby improving the dispersion effect of the additives. Subsequently, an electric push rod drives a discharge plate to open the feeding channel of the packing frame, automatically adding the mixed raw materials into the plastic processing machine. This device can pre-mix the raw materials and, in conjunction with the plastic processing machine, achieve automatic packing using a pre-dispersion addition method, thereby improving production efficiency and experimental results.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figure 1-3As shown, an automatic filling device includes a filling frame 1, a discharge plate 4, and a mixing assembly 5. A durable mounting frame 1a is installed on the lower side of the outer wall of the filling frame 1. The main function of the mounting frame 1a is to securely fix the filling frame 1 so that it can be accurately installed at the feed inlet position on the plastic processing machine, ensuring the smooth progress of the filling process. The mixing assembly 5 is set in the inner cavity of the filling frame 1. A high-efficiency power drive motor 6 is installed on the side of the filling frame 1, which can drive the mixing assembly 5 to rotate smoothly.

[0023] Two symmetrical arc-shaped blocks 1b are installed on opposite sides of the lower part of the packing frame 1. The unloading plate 4 is installed in the packing frame 1 and one of the arc-shaped blocks 1b through a precision sliding mechanism. The opposite sides of the two arc-shaped blocks 1b are finely machined to present symmetrical arc surfaces. The lower side of the other arc-shaped block 1b is formed with an inner groove 1c. The design of the inner groove 1c corresponds to the size of the unloading plate 4 and is mainly used to overlap the parallel sliding unloading plate 4 to ensure smooth unloading. Electric push rods 2 are installed on opposite sides of the outer wall of the packing frame 1. A linkage plate 3 is also set on the outer side of the packing frame 1. The extended end of the electric push rod 2 is firmly installed on the side of the linkage plate 3. The linkage plate 3 is installed on the side of the unloading plate 4, forming a control method in which the electric push rod 2 extends and retracts to drive the unloading plate 4 to unload.

[0024] As an optional implementation, the mixing and stirring assembly 5 includes a main shaft 51, a rotating sleeve 52, a drive plate 53, and rotating plates 56. The rotating sleeve 52 is rotatably mounted on one side plate of the packing frame 1. One side of the main shaft 51 is rotatably mounted inside the rotating sleeve 52, and the other side is rotatably mounted on another side plate of the packing frame 1. There are two rotating plates 56, which are arranged inside the packing frame 1. The two rotating plates 56 are fixedly mounted on the main shaft 51. Two sets of mixing and stirring plates 57 symmetrical about the main shaft 51 are installed on the opposite sides of the two rotating plates 56.

[0025] See attached document Figure 3 A drive plate 53 and a stabilizing plate 54 are provided on opposite sides of the two rotating plates 56. Both the drive plate 53 and the stabilizing plate 54 are located inside the packing frame 1. The drive plate 53 is fixedly installed on the rotating sleeve 52, and the stabilizing plate 54 is rotatably installed on the side of the main shaft 51 away from the rotating sleeve 52. Two side scrapers 55 are provided inside the packing frame 1. The two side scrapers 55 are located on opposite sides of the two sets of mixing and stirring plates 57. The two side scrapers 55 are fixedly installed on opposite sides of the drive plate 53 and the stabilizing plate 54, respectively. This ingenious arrangement allows the side scrapers 55 to fully mix the raw materials and additives located on the inner wall side of the packing frame 1 during rotation, significantly reducing the local dispersion effect of the raw materials and additives in the packing frame 1 and ensuring uniform mixing.

[0026] Furthermore, a main gear 510 and a driven gear 52a are provided on the side of the packing frame 1. A stabilizing shaft 59 is rotatably mounted on the side of the packing frame 1 via a bearing seat. The main gear 510 is mounted on the stabilizing shaft 59, and the driven gear 52a is mounted on the rotating sleeve 52. A pulley set 58 is mounted on the side of the packing frame 1, which connects the main shaft 51 and the stabilizing shaft 59. The output shaft of the drive motor 6 is mounted on the free end of the stabilizing shaft 59, and the input end of the drive motor 6 is electrically connected to the output end of a switch set on the plastic processing machine. This complex transmission system allows the drive motor 6 to drive the main shaft 51 and the rotating sleeve 52 to rotate in opposite directions by the synergistic action of the main gear 510, the driven gear 52a, and the pulley set 58. This, in turn, drives the mixing and stirring and the side scraper 55 to rotate in opposite directions, greatly improving the overall mixing effect of the raw materials and additives in the packing frame 1.

[0027] Furthermore, each set of mixing plates 57 includes two plates, which are symmetrically arranged. The mixing plates 57 are tilted at 30° relative to the plane of the rotating plate 56. This angle design allows the two sets of mixing plates 57 to mix the raw materials and additives in the filler frame 1 more evenly, thereby significantly improving the dispersion effect of the additives and ensuring the stability of product quality.

[0028] Furthermore, the side scraper 55 is set at an angle of 45° with the plane of the stabilizing plate 54 or the driving plate 53 as a reference. This unique angle design can significantly improve the scraping effect of the side scraper 55 on the mixture in the filling frame 1 towards the center of the filling frame 1 during rotation, thereby ensuring that the raw materials and additives in the filling frame 1 can be fully mixed to achieve the best mixing effect and further improve the uniformity and quality of the product.

[0029] Using the above structure, in use, raw materials and additives are added one by one into the filler frame 1. Then, the drive motor 6 is started by switching on the switch. The drive motor 6 drives the stabilizing shaft on the mixing and stirring assembly 5 to rotate. The stabilizing shaft drives the pulley group 58 and the main shaft 51, so that the main shaft 51 drives the rotating plate 56 and the mixing and stirring plate 57 to mix and stir the raw materials and additives in the filler frame 1. At the same time, the main gear 510 on the stabilizing shaft meshes, driving the driven gear 52a to rotate. The driven gear 52a drives the rotating sleeve 52 and the drive plate 53 to rotate in the opposite direction. At the same time, it drives the two side scrapers 55 to rotate in the opposite direction to the mixing and stirring plate 57, thereby tumbling and mixing the raw materials and additives. In this way, the raw materials and additives in the filler frame 1 can be fully mixed and stirred. Then, the electric push rod 2 is extended by switching on the switch. The electric push rod 2 drives the linkage plate 3 and the unloading plate 4 to slide, thereby opening the discharge channel and allowing the mixed raw materials to fall into the plastic processing machine for processing.
