Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle detection, in particular to a fat dissolving detection device for plastic particles. Background Art

[0002] Plastic melt index is also known as melt flow rate, which refers to the mass of polymer material melt passing through a standard die every ten minutes under a certain temperature and load. It is an indicator of the fluidity and processability of plastic materials. The larger the melt index, the better the fluidity. To a certain extent, it can also reflect the molecular weight of the material. The smaller the melt index, the larger the molecular weight.

[0003] In common lipolysis testing devices for plastic particles, the tray is placed directly on the placement table. When performing lipolysis testing on plastic particles, the instability of the tray is easily affected by external factors, such as slight vibrations, operator touch, or other mechanical disturbances, which can cause position shifts. In addition, the position of the tray may be slightly different each time, which will lead to differences in the results of each test, affecting the accuracy of the experiment, thereby increasing the difficulty of operation and the potential error rate.

[0004] Therefore, for the above-mentioned lipolysis detection device for plastic particles, the tray is placed directly on the placement table. When the plastic particles are subjected to lipolysis detection, the instability of the tray is easily affected by external factors, causing the position of the tray to shift, affecting the test data of the experiment. This problem urgently needs to be solved to improve the use scenario of the lipolysis detection device for plastic particles. Utility Model Content

[0005] In order to overcome the common lipolysis detection device for plastic particles, the tray is placed directly on the placement table, so that the position of the tray may be slightly different each time, which will cause differences in the results of each test, affecting the accuracy of the experiment, thereby increasing the difficulty of operation and the potential error rate.

[0006] The technical solution of the utility model is: a lipolysis detection device for plastic particles, comprising a bottom plate, a device body is fixedly provided on the upper end surface of the bottom plate, a top plate is welded to the upper end surface of the device body, a placement rack is fixedly provided on the upper end surface of the bottom plate, a plurality of mounting cylinders are fixedly installed on the inner surface of the placement rack, one end of a spring is installed inside the mounting cylinder, the other end of the spring is connected to one end of a connecting piece, the other end of the connecting piece is installed on the outer surface of the limit plate, a tray is placed on the inner side of the placement rack, the upper end surface of the tray is fixedly connected to a fixing plate, the upper end surface of the fixing plate is fixedly provided with a handle, the inner surface of the tray is installed with a bar scale plate, and the inner rear end surface of the device body is installed with a detection camera.

[0007] Preferably, when the tray is placed in the placement rack, the tray contacts the limit plate and applies a certain extrusion force. The limit plate moves inward under the pressure of the tray, thereby compressing the spring. The compression of the spring stores elastic potential energy. When the tray is fully placed in place, the spring begins to try to return to its original state, thereby generating an outward thrust on the limit plate. The outward thrust is transmitted to the tray through the limit plate, forming a stable fixed state. Even if the device vibrates slightly under the influence of external factors, the center position of the tray can be kept from shifting, ensuring that the melt flow rate measurement of the plastic particles during the detection process is not disturbed. The handle fixed on the fixed plate makes it convenient for the user to take out or place the tray. The detection camera collects and records the image of the granular material falling after melting, and uses the scale plate in the image as a reference to assist in the reference of the falling rate. The collected data is used in conjunction with the software to analyze the melt flow rate. This structure effectively prevents any unnecessary movement of the tray during the detection process, while providing intuitive image records for subsequent analysis and data processing, ensuring the high accuracy and reliability of the melt flow rate detection of the plastic particles.

[0008] Preferably, an observation window is provided on the right end face of the device body, a box door is installed on the front end surface of the device body, and four supporting feet are fixedly provided on the lower end face of the bottom plate. By providing the observation window, it is convenient for staff to observe the inside of the device, and by providing the box door, it is convenient to open the box door to place or take out the pallet.

[0009] Preferably, the upper end surface of the top plate is fixedly connected to a feed pipe, and the lower end surface of the top plate is fixedly connected to a pipeline. The pipeline and the feed pipe are interconnected, and a retaining net is fixedly connected to the inside of the pipeline. Plastic particles are placed in the feed pipe and enter the pipeline through the feed pipe. The retaining net intercepts the plastic particles, and the plastic particles wait for heating in the pipeline.

[0010] Preferably, the lower end face of the pipe is fixedly connected to a dripping head, the outer surface of the pipe is installed with an electric heating plate, and the upper end face of the feed pipe is installed with a sealing cover. When the electric heating plate is started, the pipe will be heated to melt the plastic particles. The melted plastic particles will pass through the baffle and enter the dripping head, and fall under the action of the dripping head and gravity. The detection camera is then used to capture dynamic images of the granular material flowing through the detection area after being heated and melted. These images contain real-time conditions of the flow of the granular material melt, where the scale plate serves as a reference to help measure the flow rate of the melt. By analyzing the image data collected by the camera through software, the melt flow rate can be accurately calculated. The setting of the sealing cover prevents the harmful gases generated by the melted plastic particles from being discharged through the feed pipe and causing harm to the staff.

[0011] Preferably, an air purification box is fixedly provided on the upper end surface of the top plate, and a pump body is installed on the inner bottom surface of the air purification box. During processing, especially in the process involving plastic melting and molding, volatile organic compounds, smoke, particulate matter and other harmful gases will be generated. These substances have potential hazards to human health and the environment. The air purification box can filter and discharge the harmful gases generated during the melting of plastic particles, ensuring the physical safety of the workers.

[0012] Preferably, the output end of the pump body is fixedly connected to the delivery pipe 1, the lower end face of the delivery pipe 1 is installed with a suction head, the outer surface of the delivery pipe 1 is fixedly connected to one end of the delivery pipe 2, the other end of the delivery pipe 2 is fixedly connected to the outer surface of the pipeline, and an electromagnetic valve is installed at the connection between the delivery pipe 2 and the pipeline. When the pump body is started, the harmful gas enters the delivery pipe 1 through the suction head, and then enters the air purification box through the delivery pipe 1 for treatment. When the electromagnetic valve is opened, the harmful gas inside the pipeline is transported into the air purification box for treatment.

[0013] Preferably, a control panel is installed on the left end face of the device body, and an exhaust port is provided on the upper end face of the air purification box, through which the treated harmful gases are discharged. The setting of the control panel makes it convenient for the staff to control the device.

[0014] Beneficial effects of the utility model:

[0015] 1. When the pallet is placed in the placement rack, it contacts the limit plate and exerts a certain extrusion force. The limit plate moves inward under the pressure of the pallet, thereby compressing the spring. The compression of the spring stores elastic potential energy. When the pallet is fully placed in place, the spring begins to try to return to its original shape, thus generating an outward thrust on the limit plate. The outward thrust is transmitted to the pallet through the limit plate, forming a stable fixed state. Even if the device vibrates slightly due to external factors, the center position of the pallet can be kept from shifting, ensuring that the melt flow rate measurement of the plastic particles is not disturbed during the test process.

[0016] 2. By setting up an air purification box, the air purification box can filter and treat the harmful gases generated during the melting process of plastic particles, ensuring the health safety of the staff. By starting the pump body, the harmful gases enter the delivery pipe through the suction head, and then enter the air purification box through the delivery pipe to treat the harmful gases. When the solenoid valve is opened, the harmful gases inside the pipeline are transported into the air purification box for treatment, and the treated harmful gases are discharged through the exhaust port.
