Description

Technical Field

[0001] This utility model relates to the field of polypropylene production technology, specifically to an automatic feeding device for polypropylene plastic granules. Background Technology

[0002] In the plastics manufacturing industry, polypropylene plastic granules are a commonly used raw material, and the feeding process has a crucial impact on production efficiency and product quality.

[0003] Traditional methods of feeding polypropylene plastic granules mostly rely on manual operation. Workers need to manually move the granules from the storage container to the feed port of the processing equipment. This is not only labor-intensive but also inefficient. With the increasing demand for large-scale production, the speed of manual feeding is far from meeting the production pace, becoming a bottleneck that restricts the improvement of production capacity.

[0004] While some early semi-automatic feeding equipment reduced the burden on manual labor to some extent, it had many drawbacks. For example, these devices were difficult to control the feeding amount precisely, which could easily lead to material accumulation and waste due to excessive feeding or interruption of production due to insufficient feeding. This instability in feeding amount seriously affected the consistency of product quality, increased the defect rate, and raised production costs.

[0005] Traditional feeding devices are also extremely limited in terms of automation. They usually lack effective material conveying, path planning and guidance mechanisms. Plastic granules are easy to scatter during the feeding process, which not only causes material loss, but may also pollute the production environment and affect the cleanliness and hygiene of the production workshop. In order to solve the above problems, we propose an automatic feeding device for polypropylene plastic granules. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides an automatic feeding device for polypropylene plastic granules, which solves the aforementioned problems.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution: an automatic feeding device for polypropylene plastic granules, comprising a first support frame, the top of the first support frame being U-shaped, and a groove being provided inside the U-shape; a movable plate being slidably installed in the U-shaped opening at the top of the first support frame; a second support frame being provided at the bottom of the first support frame near the U-shaped opening; a hopper being provided at the top of the first support frame, the hopper being fixedly installed at the top of the first support frame by support arms on both sides; a pushing device being provided on the side of the first support frame away from the U-shaped opening; and further comprising:

[0008] The pushing device converts the circular motion of the rotating rod into the linear motion of the connecting plate, pushes the moving plate to slide, drives the lower cylinder to move, and ensures the realization of the automatic feeding function;

[0009] A baffle, located at the top of the second support frame, provides guidance for the feed cylinder as it moves with the moving plate to the baffle through a chamfered angle and a central groove, thereby controlling the opening and closing of the hatch.

[0010] Preferably, a baffle is fixedly installed at the top of the second support frame, and the baffle has a chamfered corner on the side near the U-shaped opening in the first support frame, and a groove is formed at the middle of the baffle.

[0011] Preferably, the movable plate has a circular opening on the side near the U-shaped opening in the first support frame, and a feeding cylinder is fixedly installed in the opening. A hatch is hinged to the bottom end of the feeding cylinder.

[0012] Preferably, a slanted slider is fixedly installed at the bottom of the hatch, the angle of the slanted slider is the same as the chamfer in the baffle, and the width of the slanted slider corresponds to the groove in the baffle.

[0013] Preferably, the pushing device includes a mounting plate, a fixing block, a first connecting rod, a second connecting rod, and a connecting plate. The mounting plate is fixedly installed on the bottom end of the first support frame away from the U-shaped opening via the connecting block. The mounting plate has an opening in the middle, and a fixing block is fixedly installed inside the opening. The first connecting rod is hinged to the top of the fixing block, and a second connecting rod is hinged to the end of the first connecting rod away from the fixing block. The connecting plate is hinged to the end of the second connecting rod away from the first connecting rod.

[0014] Preferably, the connecting plate has a circular hole in the middle, and the connecting plate is fixedly installed at the bottom of the movable plate through the circular hole. A set of limiting slide rods is fixedly installed at both ends of the connecting plate near the mounting plate, and the other ends of the two sets of limiting slide rods are slidably installed in the mounting plate.

[0015] Preferably, a rotating rod is hinged to the bottom end of the first connecting rod near the second connecting rod, and the other end of the rotating rod is rotatably mounted on a mounting plate.

[0016] Compared with the prior art, the present invention provides an automatic feeding device for polypropylene plastic granules, which has the following advantages:

[0017] 1. This automatic feeding device for polypropylene plastic granules, when the feeding cylinder is driven to the baffle position by the pushing device, the door will automatically open and close according to the cooperation between the inclined slider and the baffle. The operator can control the opening and closing time and degree of the door according to the needs of different production stages, thereby controlling the amount and time of material falling, ensuring that each feeding meets the production requirements, and improving the consistency and stability of the product.

[0018] 2. This automatic feeding device for polypropylene plastic granules uses a drive motor to directly drive the rotating rod to rotate. Through the hinged connection of the first and second connecting rods, the circular motion is converted into the linear motion of the connecting plate, which in turn pushes the moving plate to slide, reducing energy loss and improving the working efficiency of the device. At the same time, the limiting slide bar on the connecting plate ensures that it moves along a straight line during the movement, avoiding swaying and deviation, and ensuring the stability of the device operation.

[0019] 3. This automatic feeding device for polypropylene plastic granules features a baffle mounted at the top of the support frame. Its chamfered angle and central groove provide precise guidance for the movement of the feeding cylinder. When the moving plate moves the feeding cylinder to the baffle position, the inclined slider at the bottom of the hatch can move smoothly along the chamfered angle and groove of the baffle, achieving automatic opening and closing of the hatch. This control method eliminates the need for manual operation, reducing the impact of human factors. Attached Figure Description

The connecting plate 13 is hinged to the end of the second connecting rod 12 away from the first connecting rod 11. The hinged connection of the first connecting rod 11 and the second connecting rod 12 converts the circular motion of the rotating rod 14 into the linear motion of the connecting plate 13, thereby pushing the moving plate 5 to slide within the U-shaped opening of the first support frame 1, so that the pushing device 7 can drive the feed cylinder 6 to move.

[0032] Furthermore, the connecting plate 13 has a round hole in the middle, and the connecting plate 13 is fixedly installed at the bottom of the moving plate 5 through the round hole.

[0050] The device consists of a first support frame 1, a second support frame 2, a baffle 3, a hopper 4, a movable plate 5, a discharge cylinder 6, a hatch 8, and a pushing device 7. The top of the first support frame 1 is U-shaped with a groove inside. The movable plate 5 is slidably installed in the U-shaped opening.
