Description

Technical Field

[0001] This utility model relates to the field of plastic particle detection technology, and in particular to a moisture tester for PET plastic particles. Background Technology

[0002] Plastic particles are essential raw materials for the production of plastic products. Particles such as polypropylene, PET, and polyethylene are used to manufacture lunch boxes and plastic packaging boxes. After production, plastic particles need to be tested for items such as appearance, heat distortion, tensile strength, and moisture content.

[0003] Currently, the insulation tray of the moisture tester for plastic particles gets hot during the heating process, resulting in high external heat. When workers remove the insulation tray and the plastic particles on top, they need to use heat insulation sleeves or other tools to cover the outside of the insulation tray to insulate it from the external heat before they can take it out. This increases the workload of the workers and reduces their work efficiency. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] To address the problem that the moisture tester for plastic particles heats up during the heating process, resulting in high external heat, which makes it inconvenient for staff to handle, increases their workload, and reduces their work efficiency.

[0006] (2) Technical solution

[0007] The technical solution of this utility model is as follows: A moisture meter for PET plastic particles includes a moisture meter body, comprising a lower heating base, an upper cover, an operation screen, a pop-out component, a weighing component, a heating coil, and a feeding tray. The operation screen is mounted on the surface of the moisture meter body, and the lower heating base is mounted on the upper surface of the moisture meter body. The upper cover is located above the lower heating base and is hinged to the lower heating base. The pop-out component is located inside the lower heating base, and weighing components are located on both sides of the pop-out component inside the lower heating base. The heating coil is located inside the lower heating base, and the feeding tray is located inside the lower heating base. After operation, the upper cover is flipped to release the pop-out component. After the heating plate is restricted, the heating plate at one end of the fixing rod is pushed out by the elastic force of spring A, thereby quickly popping the discharge plate out of the lower heating seat. The discharge plate is located above the heating plate, and carbon fiber rings are set around the discharge plate for easy and quick handling, reducing the workload of the staff and improving its efficiency. In conjunction with the weighing component, the discharge plate is first placed in the heating plate during operation. After the discharge plate discharges material, it presses down on the limiting plate, which drives the limiting plate at one end of the sliding rod to squeeze spring B. The information is transmitted to the operation screen through the weight measurement module, which facilitates the weighing of the material inside the discharge plate, data comparison, and improves the accuracy of the moisture meter.

[0008] Furthermore, the ejector assembly includes a base, a heating plate, a fixing rod, spring A, a socket, and a positioning ball. The base is installed inside the lower heating seat, and a heating plate is positioned above the base. A fixing rod is installed on the bottom surface of the heating plate. A socket adapted to the fixing rod is opened on the surface of the base. One end of the fixing rod is inserted into the socket on the surface of the base. Spring A is installed in the socket, with one end connected to one end of the fixing rod and the other end connected to the base. The feeding tray slides within the heating plate. By setting up the ejector assembly, after the operation is completed, flipping the upper cover releases the restriction on the heating plate. Under the elastic force of spring A, the heating plate at one end of the fixing rod is pushed out, thus quickly ejecting the feeding tray from the lower heating seat. The feeding tray is located above the heating plate, and a carbon fiber ring is set around the feeding tray for easy and quick retrieval, reducing the workload of workers and improving efficiency.

[0009] Furthermore, a sealing gasket is installed on one side surface of the upper cover. The sealing gasket can improve the sealing between the lower heating seat and the upper cover, and accelerate heat conduction.

[0010] Furthermore, symmetrical limit blocks are installed on one end surface of the fixed rod inserted into the base. A stabilizing groove adapted to the limit block is opened in the base. The limit block slides in the stabilizing groove. The fixed rod slides in the base through the limit block and the stabilizing groove. By installing limit blocks at both ends of the fixed rod and engaging them in the stabilizing groove, the movement range of the heating plate can be limited, thereby further improving the stability of the heating plate.

[0011] Furthermore, the inner wall of the heating plate is provided with multiple positioning balls in a ring shape. The positioning balls abut against the feeding plate. By setting the positioning balls, the feeding plate can be easily fixed in the heating plate, improving the stability of the feeding plate in the heating plate and keeping the feeding plate in a horizontal state.

[0012] Furthermore, the weighing assembly includes a slide rod, a limiting plate, spring B, and a weight measurement module. Slide rods are inserted into symmetrical through holes on the bottom of the heating plate. Limiting plates are installed at both ends of the slide rods. One end of the limiting plate slides within a hole in the base. Spring B is installed on the surface of the limiting plate inside the base. The other end of spring B abuts against the weight measurement module installed in the base. By setting up the weighing assembly, during operation, the feeding tray is first placed inside the heating plate. After the feeding tray releases material, it presses down on the limiting plate, causing the limiting plate at one end of the slide rod to squeeze spring B. The information is then transmitted to the operation screen via the weight measurement module, facilitating the weighing of the material inside the feeding tray, data comparison, and improving the accuracy of the moisture meter.

[0013] Furthermore, the surface of the heating plate is provided with a groove that matches the limiting plate, so that the limiting plate can be pressed down after the feeding plate feeds the material, so that the limiting plate is placed in the groove, which can store the limiting plate and further improve the heating efficiency of the feeding plate.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the pop-out component allows the heating plate to be quickly ejected from the lower heating seat by flipping the top cover after the operation is completed. The heating plate is then pushed out by the spring force of spring A, allowing the material discharge tray to be quickly ejected from the heating seat. The material discharge tray is positioned above the heating plate, and carbon fiber rings are arranged around its perimeter for easy and quick handling, reducing the workload of workers and improving efficiency. In conjunction with the weighing component, the material discharge tray is first placed inside the heating plate. After the material is discharged, the limiting plate is pressed down, causing the limiting plate at one end of the sliding rod to compress spring B. The information is then transmitted to the operation screen via the weight measurement module, facilitating the weighing of the material inside the material discharge tray and data comparison, thus improving the accuracy of the moisture meter.

The upper cover 3 is positioned above the lower heating base 2 and is hinged to the lower heating base 2. The pop-out component 5 is located inside the lower heating base 2. Weighing components 6 are located on both sides of the pop-out component 5 inside the lower heating base 2. The heating coil 7 is located inside the lower heating base 2. The feeding tray 8 is located inside the lower heating base 2. The pop-out component 5 includes a base 51, a heating plate 52, a fixing rod 53, a spring A 56, an insertion hole 57, and a positioning ball 58. The base 51 is mounted inside the lower heating base 2, and a heating coil 6 is positioned above the base 51. The heating plate 52 has a fixing rod 53 installed on its bottom surface. The surface of the base 51 has a socket 57 that matches the fixing rod 53. One end of the fixing rod 53 is inserted into the socket 57 on the surface of the base 51. A spring A56 is installed in the socket 57. One end of the spring A56 is connected to one end of the fixing rod 53, and the other end of the spring A56 is connected to the base 51. The feeding tray 8 slides in the heating plate 52. By setting the pop-out component 5, after the operation is completed, the upper cover 3 is flipped to release the restriction on the heating plate 52. Under the elastic force of the spring A56, the heating plate 52 at one end of the fixing rod 53 is pushed out, thereby realizing the rapid pop-out of the feeding tray 8 from the lower heating base 2. Part of the feeding tray 8 is located above the heating plate 52, and carbon fiber rings are set around the feeding tray 8 for easy and quick handling, reducing the workload of the workers and improving its efficiency.

[0026] A sealing gasket 59 is installed on one side surface of the upper cover 3. The sealing gasket 59 can improve the sealing between the lower heating seat 2 and the upper cover 3 and accelerate heat conduction.

[0027] A limiting block 54 is symmetrically installed on one end surface of the fixing rod 53, which is inserted into the base 51. A stabilizing groove 55 adapted to the limiting block 54 is opened in the base 51. The limiting block 54 slides in the stabilizing groove 55. The fixing rod 53 slides in the base 51 through the limiting block 54 and the stabilizing groove 55. By installing the limiting block 54 at both ends of the fixing rod 53 and engaging the limiting block 54 in the stabilizing groove 55, the movement range of the heating plate 52 can be limited, thereby further improving the stability of the heating plate 52.

[0028] The inner wall of the heating plate 52 is provided with a plurality of positioning balls 58 in a ring shape. The positioning balls 58 abut against the feeding plate 8. By setting the positioning balls 58, the feeding plate 8 can be easily fixed in the heating plate 52, improving the stability of the feeding plate 8 in the heating plate 52 and keeping the feeding plate 8 in a horizontal state.

[0029] Example 2:

[0030] Please see Figure 1-6 In this embodiment, the weighing component 6 includes a slide rod 61, a limiting plate 62, a spring B64, and a weight measurement module 65. Slide rods 61 are inserted into symmetrical through holes on the bottom of the heating plate 52. Limiting plates 62 are installed at both ends of the slide rods 61. The limiting plate 62 at one end of the slide rod 61 slides within a hole in the base 51. A spring B64 is installed on the surface of the limiting plate 62 within the base 51. The other end of the spring B64 abuts against the weight measurement module 65 installed within the base 51. By setting up the weighing component 6, during operation, the feeding tray 8 is first placed inside the heating plate 52. After the feeding tray 8 releases material, it presses down on the limiting plate 62, causing the limiting plate 62 at one end of the slide rod 61 to squeeze the spring B64. The information is then transmitted to the operation screen 4 via the weight measurement module 65, facilitating the weighing of the material inside the feeding tray 8, data comparison, and improving the accuracy of the moisture meter.

[0031] The surface of the heating plate 52 is provided with a groove 63 that matches the limiting plate 62, so that the limiting plate 62 can be pressed down after the feeding plate 8 feeds the material, so that the limiting plate 62 is placed in the groove 63, which can store the limiting plate 62 and further improve the heating efficiency of the feeding plate 8.

[0032] Through the above steps, during use, the pop-out component 5 is used. After the operation is completed, the upper cover 3 is flipped to release the restriction on the heating plate 52. Under the elastic force of the spring A56, the heating plate 52 at one end of the fixing rod 53 is pushed out, thereby realizing the rapid pop-out of the discharge plate 8 from the lower heating seat 2. Part of the discharge plate 8 is located above the heating plate 52, and carbon fiber rings are set around the discharge plate 8 for easy and quick handling, reducing the workload of the staff and improving its efficiency. In conjunction with the weighing component 6, during operation, the discharge plate 8 is first placed in the heating plate 52. After the discharge plate 8 discharges material, it presses down the limiting plate 62, which drives the limiting plate 62 at one end of the slide rod 61 to squeeze the spring B64. The information is transmitted to the operation screen 4 through the weight measurement module 65, which facilitates the weighing of the material inside the discharge plate 8, data comparison, and improves the accuracy of the moisture meter.
