Description

Technical Field

[0001] This utility model relates to the field of plastic processing equipment technology, and in particular to a hopper for the production of plastic pallets. Background Technology

[0002] In the production process of plastic pallets, the silo is a crucial piece of equipment for storing plastic raw materials and supplying them to subsequent processing stages. Currently, traditional silos used in plastic pallet production suffer from several problems. Firstly, the opening and closing of the discharge port largely relies on manual operation or simple mechanical control, making it difficult to achieve precise and timely automatic material handling. This often results in inaccurate discharge timing and incomplete closure, leading to material waste or supply interruptions and impacting production efficiency. Secondly, some silos have unreasonable structural designs, causing raw materials to accumulate at the bottom and hindering smooth discharge through the discharge port, requiring manual cleaning and increasing labor intensity. Furthermore, in existing automatic material handling devices, the connection and movement of related components are not stable enough, making them prone to malfunctions and affecting the normal use of the silo, thus adversely impacting the continuity and stability of plastic pallet production. Utility Model Content

[0003] To address the problems mentioned above, this utility model adopts the following technical solution: a hopper for plastic pallet production, comprising a hopper frame, on which a hopper is installed, and a discharge port is provided at the bottom. An automatic feeding and receiving device is provided at one end of the discharge port. The automatic feeding and receiving device includes small square frames installed on both sides of one end of the discharge port. The inner side of the vertical section of each small square frame is provided with a sliding groove, and a slider is slidably connected in the sliding groove. A feeding plate is connected between two sliders. A motor is installed on the top horizontal section of the small square frame. The output end of the motor passes through the top of the horizontal section of the small square frame and is connected to a lead screw. One end of the lead screw passes through the feeding plate and is rotatably connected to the bottom horizontal section of the small square frame. The lead screw is threadedly connected to the feeding plate. A gantry frame is installed on both sides of the hopper frame. A cylinder is installed on the top of the gantry frame. The output end of the cylinder passes through the gantry frame and is connected to an extrusion block.

[0004] Furthermore, the bottom of the hopper frame is funnel-shaped, and the shape of the extrusion block is adapted to the bottom of the hopper frame.

[0005] Furthermore, a sealing gasket is provided on the side of the feeding plate near the feeding port, and the sealing gasket is made of rubber.

[0006] Furthermore, the motor is a servo motor, and a dust cover is provided on the outside of the motor.

[0007] Furthermore, a bearing is provided at the connection between the lead screw and the bottom transverse section of the small square frame. The outer ring of the bearing is fixedly connected to the bottom transverse section of the small square frame, and the inner ring of the bearing is fixedly connected to the lead screw.

[0008] The advantages of this invention are as follows: By setting up an automatic feeding and receiving device, a motor drives a lead screw to rotate, causing the feeding plate to slide up and down in the cooperation of a slide groove and a slider, achieving automatic opening and closing of the feeding port. This allows for precise control of feeding and receiving, improving the degree of automation and reducing manual intervention. The bottom of the hopper frame is funnel-shaped, and the shape of the extrusion block is adapted to the bottom of the hopper frame. Driven by a cylinder, the extrusion block can extrude and push the raw material at the bottom of the hopper frame, effectively preventing raw material accumulation and ensuring that the raw material can smoothly gather and be discharged from the feeding port, thus improving feeding efficiency. A rubber sealing gasket is provided on the side of the feeding plate near the feeding port. When the feeding plate is closed, it can enhance the sealing between the feeding plate and the feeding port, preventing raw material leakage and reducing raw material waste.

[0013] See Figure 1-3 As shown, a hopper for producing plastic pallets includes a hopper frame 1, a hopper 2 mounted on the hopper frame 1, a discharge port 3 at the bottom, an automatic feeding / receiving device 4 at one end of the discharge port 3, the automatic feeding / receiving device 4 including small square frames 41 mounted on both sides of one end of the discharge port 3, each of the vertical sections of the small square frames 41 having a groove 42 on its inner side, a slider 43 slidably connected in the groove 42, a feeding plate 44 connected between the two sliders 43, a motor 45 mounted on the top horizontal section of the small square frames 41, the output end of the motor 45 passing through the top of the horizontal section of the small square frames 41 and connected to a lead screw 46, one end of the lead screw 46 passing through the feeding plate 44 and rotatably connected to the bottom horizontal section of the small square frames 41, the lead screw 46 being threadedly connected to the feeding plate 44, a gantry frame 5 mounted on both sides of the hopper frame 1, a cylinder 6 mounted on the top of the gantry frame 5, the output end of the cylinder 6 passing through the gantry frame 5 and connected to an extrusion block 7.

[0014] The bottom of the hopper frame 1 is funnel-shaped, and the shape of the extrusion block 7 is adapted to the bottom of the hopper frame 1. The funnel-shaped design of the bottom of the hopper frame 1 can guide the raw material to gather towards the feed port with the help of gravity, which helps the raw material to be discharged smoothly. The shape of the extrusion block 7 is adapted to the bottom of the hopper frame 1, so that the extrusion block 7 can fit tightly with the bottom of the hopper frame 1, which enhances the extrusion effect on the raw material, further avoids the accumulation of raw material, and significantly improves the smoothness of material discharge.

[0015] A sealing gasket is provided on the side of the discharge plate 44 near the discharge port 3. The sealing gasket is made of rubber. When the discharge plate 44 is closed, the rubber sealing gasket on the side of the discharge plate 44 near the discharge port 3 can fit tightly with the discharge port 3, which can effectively enhance the sealing performance of the discharge port 3, prevent the raw material from leaking when it is not discharging, reduce raw material waste, and ensure the sealing performance of the silo.

[0016] Motor 45 is a servo motor with a dust cover. As a servo motor, it has high-precision control characteristics and can accurately control the lifting position of the feeding plate 44 to ensure the accuracy of the opening and closing of the feeding port 3. The dust cover on the outside of motor 45 can prevent dust and other impurities from entering the motor 45, which can protect the motor 45, extend its service life, and ensure the stable operation of the automatic feeding and receiving device 4.

[0017] A bearing is provided at the connection between the lead screw 46 and the bottom transverse section of the small square frame 41. The outer ring of the bearing is fixedly connected to the bottom transverse section of the small square frame 41, and the inner ring of the bearing is fixedly connected to the lead screw 46. The bearing at the connection between the lead screw 46 and the bottom transverse section of the small square frame 41 can greatly reduce the friction when the lead screw 46 rotates, making the lead screw 46 rotate more smoothly, reducing component wear, ensuring the stability and reliability of the lifting movement of the feeding plate 44, and improving the overall service life and operational stability of the automatic feeding and receiving device 4.

[0018] Working principle: When material needs to be discharged, the servo motor 45 in the automatic feeding and receiving device is activated. The output end of the motor 45 drives the lead screw 46 to rotate. Since the lead screw 46 is threadedly connected to the feeding plate 44, and the feeding plate 44 is slidably connected to the slide groove 42 on the small square frame 41 through the slider 43, under the rotation of the lead screw 46, the feeding plate 44 slides upward along the slide groove 42, gradually opening the discharge port 3. The raw material in the hopper 2 gathers towards the discharge port under its own gravity and guided by the funnel-shaped structure at the bottom of the hopper frame 1, and is discharged through the opened discharge port 3. If there is raw material accumulation at the bottom of the hopper frame 1, the cylinder 6 at the top of the gantry frame 5 is activated. The output end of the cylinder 6 pushes the extruder... The pressing block 7 moves downward. Since the shape of the pressing block 7 is adapted to the bottom of the hopper frame 1, the pressing block 7 can squeeze the accumulated raw materials and push them towards the feed port to promote the discharge of the raw materials. When it is not necessary to discharge the material, the servo motor 45 is reversed and the lead screw 46 rotates in the opposite direction, driving the discharge plate 44 to slide down along the slide groove 42 until the sealing gasket on the discharge plate 44 is tightly fitted with the discharge port 3, closing the discharge port 3 and stopping the discharge. Throughout the process, the bearing at the connection between the lead screw 46 and the bottom transverse section of the small square frame 41 reduces the friction of the lead screw 46 rotation and ensures the smoothness of the movement. The dust cover outside the motor 45 protects the motor 45.
