Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a feeding mechanism for powdered phenolic resin packaging with a weighing function. Background Art

[0002] The unloading mechanism for powdered phenolic resin packaging with weighing function is a device specially designed for powdered phenolic resin. Its main function is to achieve accurate material weighing and ensure smooth material flow during the packaging process. When the material needs to be weighed, first open the electric valve to allow the material to enter the weighing barrel from the main storage box through the connecting pipe. After the material falls on the weighing plate, pressure will be generated. This pressure will be sensed by the weighing sensor and converted into an electrical signal output. The system will calculate the weight of the material based on this electrical signal. When the weight of the material reaches the preset value, the system will close the electric valve to stop the inflow of the material. After closing the electric valve, the material will flow out through the discharge pipe and enter the packaging equipment or other subsequent processing equipment. However, during use, since the weighing plate is inside the weighing barrel, it is not easy to place a weight of known weight on the weighing plate, so it is not easy to calibrate the weight, which is time-consuming and labor-intensive, and there are certain shortcomings.

It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0022] Some embodiments of the utility model are described below in conjunction with the accompanying drawings to provide a feeding mechanism for powdered phenolic resin packaging with a weighing function.

[0023] Embodiment 1:

[0024] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a feeding mechanism for powdered phenolic resin packaging with a weighing function, including a storage component 100, a weighing barrel 200, a weighing component 300 and a weight calibration component 400.

[0025] Specifically, the storage component 100 includes a storage bin 101, on which a bracket 102 is provided, which can support the storage bin 101, and a first electric valve 103 is provided at the bottom of the storage bin 101, which can be controlled to open, and after opening, the powdered phenolic resin in the storage bin 101 can be released for unloading.

[0026] Specifically, the weighing barrel 200 includes a cylinder body 201 arranged at the bottom of the storage bin 101 and a round rod 202 arranged at the top of the cylinder body 201, the round rod 202 is T-shaped, and a thin rope 402 can be wound around the round rod 202 to pull the weight calibration assembly 400. A second electric valve 203 is arranged at the bottom of the cylinder body 201, and the second electric valve 203 can be controlled to open. After opening, the powdered phenolic resin in the storage bin 101 can be released for unloading.

[0027] Specifically, the weighing assembly 300 includes a driving motor 301 arranged on the outside of the weighing barrel 200, a rotating plate 302 arranged at the output end of the driving motor 301, a weighing sensor 303 arranged at the top of the rotating plate 302, and a weighing plate 304 arranged on the top of the weighing sensor 303. The weighing sensor 303 can be used for weighing so as to quantitatively discharge the material, and can control the operation of the driving motor 301. The operating driving motor 301 will drive the rotating plate 302 and the weighing plate 304 to rotate, so as to pour out the powdered phenolic resin for use.

[0028] Specifically, the weight calibration assembly 400 includes a top cover 401 threadedly connected to the cylinder 201, a thin rope 402 passing through the top cover 401, a stopper 403 arranged on the top of the thin rope 402 and a weight 404 arranged on the bottom of the thin rope 402. A round hole for the movement of the thin rope 402 is opened on the top cover 401. The thin rope 402 can be released by the stopper 403. After the release, the weight 404 will contact the weighing plate 304 due to the effect of gravity. After the contact, the thin rope 402 is in a loose state and the weight can be ignored. Then, the weight 404 with a known weight can be weighed and calibrated for use.

[0029] Embodiment 2:

[0030] Reference Figure 1 and Figure 5 , which is the second embodiment of the utility model, which is different from the first embodiment in that it also includes a discharge height adjustment component 500, which includes a discharge pipe 501 inserted into the bottom of the weighing barrel 200, a fastening knob 502 threadedly connected to the discharge pipe 501, and a thin tube 503 arranged at the bottom of the discharge pipe 501. The fastening knob 502 can be loosened. After the fastening knob 502 is loosened, the discharge pipe 501 can be moved up and down, so that the height of the discharge pipe 501 can be adjusted to facilitate discharge. At the same time, the thin tube 503 can prevent the powdered phenolic resin from splashing to the outside.

[0031] The working principle and use process of the utility model are as follows: during calibration, the thin rope 402 can be released through the stopper 403. After the release, the weight 404 will contact the weighing plate 304 due to the effect of gravity. After the contact, the thin rope 402 is in a loose state and the weight can be ignored. Then, the weight 404 of known weight can be weighed and calibrated for use. After calibration, the thin rope 402 can be pulled through the stopper 403 until the weight 404 is inside the top cover 401. Then, the thin rope 402 is wound around the round rod 202, which effectively avoids the problem that the weight 404 affects the feeding. During weighing, the external control device first controls the opening After the first electric valve 103 is opened, the powdered phenolic resin will fall onto the weighing plate 304 and be weighed by the weighing sensor 303. When the appropriate weight is reached, the external control device will close the first electric valve 103 and control the operation of the drive motor 301. The operation of the drive motor 301 will drive the rotating plate 302 and the weighing plate 304 to rotate, so that the powdered phenolic resin can be poured out. Finally, the tightening knob 502 can be loosened. After the tightening knob 502 is loosened, the discharge pipe 501 can be moved to adjust the height of the discharge pipe 501 for unloading, and at the same time, the fine tube 503 can be used to prevent the powdered phenolic resin from splashing outside.
