Description

Technical Field

[0001] This utility model relates to the technical field of blow molding of plastic buckets, and specifically to a crushed material suction device for blow molding. Background Technology

[0002] Diamond, commonly known as "diamond," is a mineral composed of pure carbon and is the hardest substance in nature. Since the 18th century, when it was confirmed that diamond is composed of pure carbon, people began to study synthetic diamonds. It was only in the 1950s, through advancements in high-pressure research and testing technology, that true success and rapid development were achieved. Synthetic diamonds are now widely used in various industries and crafts.

[0003] The integrated crushing and vacuum suction device saves space by combining crushing and vacuum suction functions. However, the dust generated in the crushing chamber can easily enter the vacuum pipeline or fan with the airflow. The integrated structure lacks effective isolation due to its compact space. Especially when processing wet plastics, the debris and dust can easily mix and clog the filter structure, requiring frequent shutdowns for disassembly and cleaning. Utility Model Content

[0004] The purpose of this invention is to provide a material feeding device for blow molding, so as to solve the above-mentioned defects caused by the prior art.

[0005] A material feeding device for blow molding includes a powder tank, a servo motor, a suction tank, and a stainless steel filter element. The servo motor is located directly above the powder tank and is connected to the top of a drive shaft via a coupling. A separation mechanism is located on the outside of the powder tank, which achieves precise separation between the powder tank and the suction tank through mechanical linkage. Residual material inside the suction tank is cleaned as needed for maintenance. A feeding box door is hinged to the outside of the powder tank. A scraping mechanism is located inside the suction tank. When the scraping mechanism drives an inclined brush rod to rotate, the inclined brush rod rotates due to its tilt angle, thus cleaning the inside of the suction tank and the stainless steel filter element.

[0006] Preferably, the separation mechanism includes fasteners, annular brackets, positioning holes, vertical guide rods, and crushing blades. Fasteners are connected through the outer side of the annular brackets, and the tail end of the fasteners is connected to the vertical guide rods. Multiple sets of positioning holes are equally spaced on the outer side of the vertical guide rods. The crushing blades are equally spaced inside the powder tank. A drive shaft is keyed to the outer side of the crushing blades. The bottom end of the powder tank has a semi-circular structure, and the inner end of the annular bracket is fitted to the outer side of the powder tank.

[0007] Preferably, the powder tank is connected to multiple sets of vertical guide rods through an outer ring bracket, and the bottom end of the vertical guide rod is connected to the top end of the suction tank.

[0008] Preferably, the scraping mechanism includes a suction tank, an inclined brush rod, an eccentric wheel, a drive shaft, a feeding blade, and a stainless steel filter element. The top of the suction tank has a circular opening structure. An eccentric wheel is provided inside the suction tank. The drive shaft is connected through the outer side of the eccentric wheel. The bottom end of the drive shaft is connected to the bottom end of the suction tank. Feeding blades are symmetrically arranged on the outer side of the drive shaft. The stainless steel filter element is installed on the outer side of the suction tank.

[0009] Preferably, the suction tank is keyed to the drive shaft via an internally provided eccentric wheel, and the eccentric wheel is connected to the bottom end of the inclined brush rod via a tapered threaded hole at its top.

[0010] Preferably, the suction tank is fitted to the outer side of the inclined brush rod through a stainless steel filter element installed on one side, and the overall suction tank has an inverted frustum structure.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. The vertical lifting system, consisting of a ring bracket, positioning holes, and vertical guide rods, achieves precise separation of the powder tank and the suction tank through mechanical linkage. After the tanks are quickly separated, the powder tank can be cleaned or the material replaced directly without stopping the entire machine, thus improving production efficiency.

[0013] 2. The scraping mechanism is designed with an eccentric wheel driving an oblique brush rod to clean the tank wall and filter element. The eccentric wheel, based on the bottom diameter of the suction tank, drives the oblique brush rod to form an angled contact with the inner wall of the tank and the outer side of the stainless steel filter element. A single rotation cleans two key surfaces simultaneously. The eccentric motion eliminates the cleaning zone. When the eccentric wheel drives the brush rod to revolve, the brush generates a rotational effect due to the tilt angle, covering the bottom edge of the tank and the root of the filter element, which are traditional dead corners.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 5 As shown, a material feeding device for blow molding includes a powder tank 1, a servo motor 2, a suction tank 10, and a stainless steel filter element 15. The servo motor 2 is located directly above the powder tank 1 and is connected to the top of a drive shaft 13 via a coupling. A separation mechanism 7 is located on the outside of the powder tank 1. The separation mechanism 7 achieves precise separation between the powder tank 1 and the suction tank 10 through mechanical linkage. Residual materials inside the suction tank 10 are cleaned according to maintenance needs. A feeding box door 8 is hinged to the outside of the powder tank 1. A scraping mechanism 9 is located inside the suction tank 10. When the scraping mechanism 9 drives the inclined brush rod 11 to revolve, the inclined brush rod 11 generates a rotation effect due to its tilt angle, thus cleaning the inside of the suction tank 10 and the stainless steel filter element 15.

[0023] In this embodiment, the separation mechanism 7 includes a fastener 3, an annular bracket 4, positioning holes 5, a vertical guide rod 6, and a crushing blade 16. The fastener 3 is connected through the outer side of the annular bracket 4, and the vertical guide rod 6 is connected to the tail end of the fastener 3. Multiple sets of positioning holes 5 are equally spaced on the outer side of the vertical guide rod 6. The crushing blades 16 are equally spaced inside the powder tank 1, and a drive shaft 13 is keyed to the outer side of the crushing blades 16. The bottom end of the powder tank 1 has a semi-circular structure. The inner end of the annular bracket 4 is fitted to the outer side of the powder tank 1. The annular bracket 4 drives the outer side of the powder tank 1 to move vertically up and down, thereby cleaning the powder tank 1 according to the replacement requirements.

[0024] In this embodiment, the powder tank 1 is connected to multiple sets of vertical guide rods 6 through an outer ring bracket 4. The bottom end of the vertical guide rod 6 is connected to the top end of the suction tank 10. The outer side of the powder tank 1 is positioned and guided by the annular vertical guide rod 6 to prevent the powder tank 1 from shaking.

[0025] In this embodiment, the scraping mechanism 9 includes a suction tank 10, an inclined brush rod 11, an eccentric wheel 12, a drive shaft 13, a feeding blade 14, and a stainless steel filter element 15. The top of the suction tank 10 has a circular opening structure. An eccentric wheel 12 is arranged inside the suction tank 10. The drive shaft 13 is connected through the outer side of the eccentric wheel 12. The bottom end of the drive shaft 13 is connected to the bottom end of the suction tank 10. Feeding blades 14 are symmetrically arranged on the outer side of the drive shaft 13. The stainless steel filter element 15 is installed on the outer side of the suction tank 10. The rotating feeding blades 14 can interrupt the static accumulation of materials and ensure continuous and uniform feeding.

[0026] In this embodiment, the suction tank 10 is keyed to the drive shaft 13 via an internally provided eccentric wheel 12. The eccentric wheel 12 is connected to the bottom end of the inclined brush rod 11 through a tapered threaded hole at its top. The tapered threaded hole is used to position the inclined brush rod 11, thereby driving the inclined brush rod 11 to rotate and clean.

[0027] In this embodiment, the suction tank 10 is attached to the outside of the inclined brush rod 11 through a stainless steel filter element 15 that is disposed through one side. The suction tank 10 has an inverted frustum structure. The suction tank 10 collects the crushed material and then cleans one side of the stainless steel filter element 15 through the inclined brush rod 11.

[0028] In practical applications, this blow molding pulverized material suction device includes the following functions:

[0029] Step 1: Before use, select the length of the powder tank 1 of the appropriate specification according to the amount of material to be processed at one time. Then, install the servo motor 2 on the top of the powder tank 1. During use, the bottom of the vertical guide rod 6 arranged in a ring is connected to the top of the suction tank 10, so that the vertical guide rod 6 passes through the outer side of the ring bracket 4, thereby positioning the outer side of the powder tank 1, so that the bottom opening of the powder tank 1 is connected to the top of the suction tank 10. Then, the ring bracket 4 and the vertical guide rod 6 are fastened by the symmetrically arranged fasteners 3.

[0030] Step 2: After the batch of plastic is crushed and sucked up, the fastener 3 is used to separate the vertical guide rod 6 from the connection point of the ring bracket 4. When the ring bracket 4 set on the outside of the suction tank 10 is vertically guided by the vertical guide rod 6, the suction tank 10 will be pulled vertically upward, so that the top of the powder tank 1 and the suction tank 10 are separated, the residual material inside the suction tank 10 is cleaned up, and the stainless steel filter element 15 is replaced at the same time.

[0031] Step 3: During processing, the operator opens the feeding box door 8 and injects plastic into the powder tank 1. By turning on the servo motor 2, the servo motor 2 drives the drive shaft 13 and the crushing blade 16 to rotate. The crushing blade 16 crushes the plastic. The material is directly injected into the suction tank 10 through the through hole at the bottom of the powder tank 1. The stainless steel filter element 15 on the outside of the suction tank 10 filters the sucked material. The vacuum pump runs, creating a negative pressure environment inside the suction tank 10. The air pressure inside the suction tank 10 decreases, and the external crushed material is sucked in from the suction port through the pressure difference.

[0032] Step 4: The fine powder carried by the airflow must pass through the stainless steel filter element 15 before entering the vacuum pump pipeline. The suction tank 10 is equipped with a scraping mechanism 9. The drive shaft 13 drives the eccentric wheel 12 to rotate. The eccentric wheel 12 is equipped with an inclined brush rod 11 that rotates. The inclined brush rod 11 brushes the inner wall of the suction tank 10 and the outer side of the stainless steel filter element 15. At the same time, the material-pulling blade 14 repeatedly moves the material to avoid plastic accumulation affecting the suction efficiency and to prevent some debris from clogging the surface of the stainless steel filter element 15, thereby affecting the filtration effect of the stainless steel filter element 15.

[0033] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
