Abstract
Description
Technical Field
[0001] This utility model relates to the field of spiral feeder technology, specifically to a feeding mechanism for processing plastic products. Background Technology
[0002] In the plastics processing industry, the feeding stage is a crucial step in the entire production process, and its efficiency and stability directly affect the quality and output of subsequent processing. Traditional feeding methods for plastics processing mostly involve manual pouring or simple mechanical conveying devices; however, these methods have revealed many problems in practical applications.
[0003] When raw materials are manually poured directly, it is difficult to control the pouring speed and amount, leading to accumulation at the inlet of conveying or processing equipment. For example, when adding plastic granules to the hopper of an extruder or injection molding machine, pouring in too many granules at once will cause them to accumulate in the hopper, hindering the smooth flow of material and potentially causing blockages in the conveying pipes, affecting the continuity of feeding, and ultimately leading to production interruptions and reduced efficiency. Moreover, manual operation is inefficient, requiring frequent material replenishment, which increases labor costs and intensity.
[0004] Furthermore, the conveying process of plastic granules generates significant noise due to friction between granules and collisions with the conveying equipment. Prolonged exposure to high-noise environments can harm the health of operators, causing conditions such as hearing loss and neurasthenia. Noise also interferes with communication between operators, impacting work efficiency and production safety. Additionally, some plastic powder raw materials are prone to moisture absorption and clumping during transport, potentially clogging the discharge pipe. This technical solution addresses these issues by proposing a feeding mechanism for plastic product processing. Utility Model Content

The technical solution of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.
[0024] Example 1: A feeding mechanism for processing plastic products. The base frame 1 adopts a rectangular steel frame structure, with four universal rollers 3 with brake locking function fixed to the four corners of its bottom by bolts. A drive motor 2 is bolted to the top left of the base frame 1. The output shaft of the drive motor 2 is connected to the power input end of the reducer 4 through a coupling. The reducer 4 is fixed to the top of the base frame 1 by bolts. The output shaft of the reducer 4 is fixedly connected to the bottom port shell of the feed pipe 61 of the spiral feeding pipe 6. The bottom end of the spiral feed blade 64 is fixed to the output shaft of the reducer 4 by a flat key. The feed pipe 61 is inclined at 15 degrees with the left side lower than the right side. The feed funnel 5 is welded to the top left side, and a through hole is opened on the bottom right side for fixing the discharge trough 81. The spiral feed blade 64 is rotatably installed in the inner cavity of the feed pipe 61. Two sections of polyester fiber sound insulation cotton sleeve 62 are adhered to the outer surface with epoxy resin adhesive. The middle section is fixed to the support frame 7 by two stainless steel clamps. The bottom of the support frame 7 is welded to the top right side of the base frame 1. The end cap 63 is fixed to the right end of the conveying pipe 61 by four M6 screws. The discharge trough 81 of the vibrating discharge pipe 8 passes through the bottom through hole of the conveying pipe 61 and is welded to the inverted V-shaped distribution trough 82. The discharge trough 83 is welded to the two bottom ends of the inverted V-shaped distribution trough 82 respectively. A miniature vibration motor 84 is fixed to the side wall of each of the four discharge troughs 83 by bolts.
[0025] Example 2: Based on Example 1, the base frame 1 is modified to use an aluminum alloy profile splicing structure, and the universal rollers 3 are made of nylon. The drive motor 2 and the reducer 4 are connected by a flexible coupling, and the spiral feed plate 64 is made of carbon steel and galvanized. The two sections of sound insulation cotton sleeve 62 on the outer ring of the feed pipe 61 are designed in segments with a 5mm gap in the middle. The support frame 7 is modified to a height-adjustable telescopic structure, and the height is adjusted by positioning pins. A guide plate is added inside the inverted V-shaped feed trough 82 of the vibrating discharge pipe 8, and the discharge trough 83 is a detachable structure connected to the inverted V-shaped feed trough 82 through a flange. The four vibrating motors 84 are controlled by a parallel circuit.
[0026] Example 3: The base frame 1 adopts a thickened steel plate welded structure, and the universal rollers 3 are rubber silent wheels. The drive motor 2 is equipped with a frequency converter to realize speed regulation function, and the reducer 4 adopts a worm gear structure. The inner wall of the feed pipe 61 of the spiral feeding pipe 6 is sprayed with a ceramic wear-resistant coating, and the pitch of the spiral feed blades 64 gradually increases from left to right. The sound insulation cotton sleeve 62 is wrapped with an aluminum foil protective layer, and rubber shock-absorbing pads are added at the connection between the support frame 7 and the feed pipe 61. A filter screen is installed at the inlet of the discharge trough 81 of the vibrating discharge pipe 8, the included angle of the inverted V-shaped distribution trough 82 is changed to 120 degrees, a movable baffle is added to the end of the discharge trough 83, and the vibration motor 84 is controlled by wireless remote control for start and stop.
[0027] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:
[0028] First, the plastic granules to be processed are poured into the feed funnel 5 connected to the top left of the feed pipe 61. Under the action of gravity, the plastic granules enter the inner cavity of the feed pipe 61. At this time, the drive motor 2 installed on the top left of the base frame 1 starts, and its power is transmitted to the connected reducer 4 through the power input end. After the reducer 4 adjusts the speed of the power, it drives the spiral feed plate 64 to rotate through the power output end. Since the feed pipe 61 is inclined with the left side lower and the right side higher and the spiral feed plate 64 is rotated and set in it, the plastic granules move to the upper right along the feed pipe 61 under the rotation of the spiral feed plate 64. During the movement, the two sections of sound insulation cotton sleeve 62, which are adhered and fixed to the outer surface of the feed pipe 61 by adhesive, can reduce the noise generated by the operation of the equipment.
[0029] When the plastic granules move to the through hole on the right side of the bottom surface of the conveying pipe 61, they enter the feeding trough 81 of the vibrating discharge pipe 8, which is connected to it. The space between the feeding trough 81 and the inverted V-shaped distribution trough 82 is interconnected. The plastic granules fall from the feeding trough 81 into the inverted V-shaped distribution trough 82. Because the inverted V-shaped distribution trough 82 is an inverted V, the plastic granules will flow to the two bottom ports of the inverted V-shaped distribution trough 82, and then enter the discharge trough 83 fixedly connected to the two ports. At this time, the vibration motors 84 fixed on the four side walls of the discharge trough 83 start to generate vibration, so that the plastic granules in the discharge trough 83 can be discharged more smoothly, completing the feeding process. The bottom port of the conveying pipe 61 is fixedly connected to the right side of the housing of the reducer 4 to ensure the stability of power transmission. The output shaft of reducer 4 is fixedly connected to the bottom end of the spiral feeder 64 to ensure that the spiral feeder 64 can rotate with the output shaft of reducer 4; the end cap 63 connected to the right port of the feed pipe 61 by screws can prevent plastic particles from leaking out from the right port, and at the same time facilitate the cleaning and maintenance of the inside of the feed pipe 61; the support frame 7 is fixedly connected to the middle section of the outer ring of the feed pipe 61 by clamp, and its bottom end is fixedly connected to the right side of the top surface of the base frame 1, which plays the role of supporting the feed pipe 61 and ensuring the stability of the feed pipe 61 during operation; the four corners of the bottom surface of the base frame 1 are all bolted with universal rollers 3, which facilitates the movement of the entire feeding mechanism, and the universal rollers 3 have a brake locking function that can fix the equipment after it reaches the designated position to prevent the equipment from moving during operation.
