Description

Technical Field

[0001] This utility model relates to the field of material feeding technology in plastic production, and in particular to a raw material feeding device. Background Technology

[0002] Plastic products are everyday and industrial goods made primarily from plastics. This includes products manufactured using processes such as injection molding and thermoforming. Plastics are a class of malleable synthetic polymers that, along with synthetic rubber and synthetic fibers, form the three essential synthetic materials for daily life. Specifically, plastics are materials made primarily of natural or synthetic resins with various additives, which can be molded into specific shapes under certain temperature and pressure conditions and retain those shapes at room temperature.

[0003] Chinese Patent No. CN221139909U discloses a raw material feeding device for plastic product manufacturing, including a base and a fixed frame. The upper surface of the base has grooves on both sides, with sliders slidably connected within the grooves. Movable blocks are mounted on the upper surfaces of the sliders, and the top of the movable blocks is movably connected to a first connecting rod via a rotating shaft. A first mounting block is mounted on one side of the pair of grooves on the upper surface of the base, with a second connecting rod movably connected to the top of the first mounting block via a rotating shaft. One end of the second connecting rod is movably connected to one side of the first connecting rod via a rotating shaft. Second mounting blocks are mounted on the other side of the pair of grooves on the upper surface of the base. This device can freely adjust the height of both ends of the conveyor belt, allowing the feed hopper and discharge port to adapt to different raw material feeding and output positions. Simultaneously, it can screen raw material particles, removing large particles that do not meet requirements, thus improving product quality.

[0004] Existing plastic production feeding devices have complex components for adjusting the applicable height of the fixing frame, which leads to complicated regular maintenance and reduced practicality. Consequently, large particles of raw material that do not pass through the filter screen cannot be discharged quickly and require manual operation, further reducing the practicality of the device and the efficiency of material feeding in production.

[0022] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0023] Example 1

[0024] like Figure 1 - Figure 3 As shown, this utility model proposes a raw material feeding device, comprising a fixed frame 1, a conveyor belt 2, a feeding assembly 3, and a support base 4. The fixed frame 1 has a base plate 101 connected to its lower two sides, with the two ends of the base plate 101 connected by a splicing plate 102. An electric telescopic column 103 is connected below the splicing plate 102. A filter element is connected to the feeding end of the fixed frame 1 and to the conveyor belt 2. The feeding assembly 3 is connected to one end of the fixed frame 1 and above the conveyor belt 2. The support base 4 is connected to the outer wall of the fixed frame 1. A hydraulic cylinder 401 is connected to the support base 4, and the driving end of the hydraulic cylinder 401 passes through the fixed frame 1 and connects to a pusher plate 402, which is movably connected to the filter element. The conveyor belt 2 is connected to the inner wall of the fixed frame 1, and the conveyor belt 2 is used for feeding plastic production raw materials, conveniently increasing the efficiency of plastic production raw material feeding and improving the overall efficiency of the raw material feeding device.

[0025] Further explanation: The feeding assembly 3 includes a feeding hopper 301 connected to the feeding end of the fixed frame 1. The feeding hopper 301 is connected to a motor 302, and the output end of the motor 302 is connected to a rotating shaft 303. The rotating shaft 303 rotates through the inside of the feeding hopper 301 and connects to a control plate 304. When the plastic production raw materials are in use through the feeding hopper 301, the motor 302 is started. The output end of the motor 302 causes the rotating shaft 303 to rotate. The rotating shaft 303 drives the outer wall control plate 304 to rotate inside the feeding hopper 301. During the entry of the raw materials, the two control plates 304 control the amount of raw materials entering. At the same time, the control plates 304 exert pressure on the raw materials during rotation, preventing the raw materials from clogging inside the feeding hopper 301. This improves the functionality of the raw material feeding device and increases the efficiency of plastic production feeding.

[0026] Further explanation: A control plate 403 is movably connected above the fixed frame 1. The control plate 403 is mounted on the drive end of the electric push rod 404, which is installed in a groove b on the fixed frame 1. The fixed frame 1 has a discharge port b, which is connected to the control plate 403 and used to control the opening or closing of the discharge port b. The pusher plate 402 is moved to the side of the discharge port b by a hydraulic cylinder 401 for discharging large-particle raw materials. The discharge port b and the pusher plate 402 have the same structure, which facilitates the use of the pusher plate 402 to discharge large-particle raw materials. The control plate 403 is then used to open or close the discharge, which improves the ease of use of the components of the plastic production raw material feeding device and enhances the practicality of the raw material feeding device.

[0027] Example 2

[0028] like Figure 1 and Figure 2 As shown, the present invention proposes a raw material feeding device. Based on the above embodiments, this embodiment also details the specific components of the fixing frame 1 and their assembly method.

[0029] To further explain, the fixed frame 1 is provided with a groove a, and an electric telescopic rod is connected inside the groove a. The drive end of the electric telescopic rod is connected to a baffle 104; a side plate 105 is connected to the feeding end of the fixed frame 1. By activating the electric telescopic rod, the drive end of the electric telescopic rod causes the baffle 104 to move upward within the groove a, thereby increasing the usability of the fixed frame 1 and preventing side leakage of plastic production raw materials during the feeding process on the conveyor belt 2, thus facilitating the use of additional raw material feeding devices.

[0030] Further explanation: The filter element includes a filter screen 106 connected to the inner side of the feeding end of the fixed frame 1. A discharge plate 107 is connected below the filter screen 106, and the discharge end of the discharge plate 107 is connected to the discharge port a, which is located on the fixed frame 1. The filter screen 106 is connected to the feeding end of the conveyor belt 2 and is inclined towards the discharge port a. The filter screen 106 is provided with filter holes, which filter the plastic raw materials. The filter screen 106 is inclined, and large particles that are not filtered out accumulate towards the inner side of the feeding end of the fixed frame 1. When they accumulate to a certain range, they are discharged by the pusher plate 402. This facilitates the discharge of large particles of raw materials, improves the speed of discharge of large particles from the feeding device, and enhances the practicality of the plastic production raw material feeding device.

[0031] The working principle of this utility model is as follows: Plastic production raw materials are fed and transported by a feeding device. The raw materials are conveyed by a conveyor belt 2 to a filter screen 106. The filter screen 106 filters the plastic raw materials through filter holes. The raw materials flowing through the filter holes flow to a discharge plate 107. The discharge plate 107 is tilted, allowing qualified raw materials to be fed through discharge port a. Unqualified raw materials, also tilted, flow to the inner wall of the discharge end of the fixed frame 1. Based on the amount of unqualified raw materials stored, the hydraulic cylinder 401 is activated. The driving end of the hydraulic cylinder 401 moves the pusher plate 402 towards the discharge port b. The pusher plate 402 moves along the upper surface of the filter screen 106, pushing the unqualified raw materials on the filter screen 106 to the discharge port b. During the unqualified raw material discharge operation, the control plate 403 moves upward via the electric push rod 404, opening the discharge port b. This, in conjunction with the pusher plate 402, discharges the unqualified raw materials from the feeding device, facilitating the discharge of unqualified raw materials. When unqualified raw materials accumulate on the filter screen 106, the control plate 403 resets via the electric push rod 404, closing the discharge port b. This facilitates the operation of the plastic production raw material feeding device and improves the efficiency of plastic production raw material feeding.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
