Description

Technical Field

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

[0002] Plastic processing, also known as plastic molding processing, is a general term for various processes that transform synthetic resins or plastics into plastic products. It is a major production sector in the plastics industry. Plastic processing generally includes plastic batching, molding, machining, joining, finishing and assembly. The latter four processes are carried out after the plastic has been molded into products or semi-finished products, and are also known as secondary plastic processing. When processing plastic granules, the raw materials need to be weighed, and then the weighed raw materials are poured into the processing equipment to achieve quantitative feeding.

[0003] A patent with publication number CN218314668U discloses a feeding device for producing plastic granules with a weighing function. The feeding device uses an electronic weigher, and the output end of the electric push rod and one side of the limiting frame are provided with a tilting mechanism for tilting the raw material in the barrel. The outer side and the inner side of the barrel are provided with a pushing mechanism for cleaning the inner wall of the barrel.

[0004] Although the above-mentioned feeding device uses an external controller to move the electric push rod upward, and the spur gear contacts the rack when the cylinder rises to a certain height, and then the spur gear rotates along the rack as the cylinder rises, lifting and tilting the feeding hopper, the driving distance is relatively limited by the electric push rod alone, the moving distance is relatively short, the applicable range is narrowed, and the feeding hopper cannot be well fixed when tilting, resulting in relatively poor stability. In order to address the above problems, an improved and upgraded plastic granule raw material feeding device with weighing function is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a plastic granule raw material feeding device with weighing function to solve the problems mentioned in the background art.

[0006] To solve the above problems, the following technical solutions are provided:

[0007] Design a plastic granule raw material feeding device with weighing function, including a support base, a fixing plate fixedly installed on the inner wall of the support base, and an electronic weighing device installed on the upper end of the fixing plate. A lifting component is installed on the upper end of the support base, and fixing frames are fixedly installed on both sides of the outer wall of the support base. A placement plate is installed above the electronic weighing device, and a fixing component is installed on the upper surface of the placement plate. A material loading hopper is installed inside the fixing component. The lifting component includes a drive motor, a connecting rod, and a worm gear. The drive motor is fixedly installed on the upper end of the support base, and the two ends of the connecting rod are rotatably installed inside two mounting seats, with one end of the connecting rod fixedly connected to the drive motor.

[0008] Furthermore, a worm gear is fixedly connected inside the connecting rod, and a worm wheel is meshed with the outer wall of the worm gear. The bottom of the worm wheel is rotatably mounted on the support base, and limit grooves are formed inside the two fixing frames.

[0009] Furthermore, both of the aforementioned fixing frames have threaded rods rotatably installed inside, and one end of each threaded rod is fixedly connected to a worm gear. Guide blocks are threadedly connected to the outer walls of both threaded rods.

[0010] Furthermore, the outer walls of both guide blocks are slidably connected to the inside of the fixed frame, and a rotary cylinder is fixedly installed inside each guide block. One end of each rotary cylinder is connected to a mounting bracket, and the two mounting brackets are installed on both sides of the outer wall of the placement plate.

[0011] Furthermore, the fixing component includes a placement frame, a guide frame, and a moving cylinder. The placement frame is fixedly mounted on the placement plate, and the placement frame has several placement slots inside. The number of guide frames is set to four, and each guide frame has a mounting plate fixedly connected to its upper end.

[0012] Furthermore, a movable cylinder is fixedly installed inside the mounting plate, and an anti-slip clamping plate is fixedly connected to one end of the movable cylinder. Guide telescopic rods are slidably connected to both sides of the movable cylinder inside the mounting plate, and one end of the guide telescopic rod is connected to the anti-slip clamping plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model device includes a drive motor, connecting rods, worm gears, worm wheels, threaded rods, guide blocks, and moving cylinders. The drive motor drives the connecting rods on the two mounting seats to rotate, which in turn drives the two worm gears on the outer wall to mesh with the worm wheels, causing the two worm wheels to drive the two threaded rods to rotate inside the fixed frame. The two threaded rods then drive the placement plates on the two guide blocks to rise and fall. By driving the rotary cylinders on the two guide blocks, the placement plates on the fixed frame are flipped to discharge plastic granules from the loading barrel. This is beneficial for discharging from platforms at higher distances, increasing the applicability of the discharging device, and the structure is simple.

[0015] 2. This utility model device is equipped with components such as a placement frame, guide frame, moving cylinder, anti-slip clamping plate, and guide telescopic rod. By driving the moving cylinders on the upper mounting plates of the four guide frames on the placement frame, the four moving cylinders drive the anti-slip clamping plate to move and fix the filling barrel. At the same time, the anti-slip clamping plate is limited by the guide telescopic rod when moving. It can place filling barrels of different sizes on the placement slots of the placement frame, which is beneficial for assembling filling barrels of various sizes and effectively fixing them, improving the stability of the filling barrel when unloading, and is simple to operate.
