Description

Technical Field

[0001] The invention relates to the field of extruders, and in particular to a plastic particle feeding device for a cable processing extruder. Background Art

[0002] The cable processing extruder is a device specially used for manufacturing wires and cables. When producing wires and cables, plastic particles are transported to the extruder through a feeding device. The extruder heats and melts the plastic particles and then extrude them into an insulating layer or sheath.

[0003] However, due to the complex production environment of the factory, the raw materials often contain a certain amount of moisture. Since the existing feeding device lacks pre-dehumidification function, this will affect the production quality of the cable, resulting in defective products and cost losses. In addition, the wet raw materials entering the extruder will shorten the service life of the extruder and damage the extruder.

[0004] In response to the above problems, an existing patent provides a plastic particle feeding device for an extruder for cable processing (publication number: CN104827642B), which dehumidifies the plastic particles by setting a hot air device. When the plastic particles move upward along the conveying plate, the air outlet component of the hot air device dehumidifies the plastic particles.

[0005] However, in actual use, when the plastic particles are dehumidified by blowing with a hot air device, on the one hand, the plastic particles are prone to stick together after dehumidification, which can easily cause the discharge port to be blocked; on the other hand, due to the difference in humidity among plastic particles in different batches, dehumidifying the plastic particles only by a hot air device can easily cause the plastic particles to be too dry or the humidity to be too high. If the plastic particles are too dry, they will become brittle, bubbles and poor welding may appear on the product surface during the extrusion process, and the dehumidification accuracy is low.

[0006] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0048] This embodiment is used to solve the problem that due to the difference in humidity among different batches of plastic particles, dehumidification of plastic particles only by hot air device may easily cause the plastic particles to be too dry or the humidity to be too high. Overdrying of plastic particles will cause the particles to become brittle, bubbles and poor welding may occur on the product surface during the extrusion process, and the dehumidification accuracy is low.

[0049] See also Figure 6 - Figure 8 As shown, the present invention also includes a shell body 404, which is located on one side of the warehouse body 401, and the shell body 404 is fixedly connected to the warehouse body 401. A vacuum generator 6 is fixedly installed on the side of the shell body 404 away from the warehouse body 401, and a through hole 405 is provided on the side of the warehouse body 401 close to the shell body 404.

[0050] A bin body 3 410 is fixedly installed at the bottom of the fixed plate 402, a dispersion plate 411 is movably installed in the bin body 3 410, a cross bar 412 is fixedly installed on the dispersion plate 411, a motor 3 413 is fixedly installed on one side of the bin body 3 410, and the output end of the motor 3 413 is fixedly connected to the cross bar 412, a through hole 3 414 is opened at the bottom of the bin body 2 401 and the center of the fixed plate 402, and the bin body 2 401 is connected to the bin body 3 410 through the through hole 3 414.

[0052] The bottom of the bin body three 410 is fixedly connected to the shell body one 5, and a push screw rod two 502 is movably installed inside the shell body one 5. The top of the push screw rod two 502 is fixedly connected to the output end of the motor two 501, and the interior of the shell body one 5 is connected with the interior of the bin body one 201 and the bin body three 410.

[0053] The control panel is provided with a processor, a data acquisition module, a data analysis module and a signal execution module; the data acquisition module is used to collect the temperature and humidity Qi and the elastic modulus Ei of the plastic particles inside the second bin body 401 during the use of the second bin body 401, and send the temperature and humidity Qi and the elastic modulus Ei of the plastic particles to the data analysis module via the processor;

[0054] It should be noted that: the temperature and humidity Qi is expressed as the maximum and minimum values ​​of the temperature and humidity in the plastic particle environment inside the second bin 401 within the time threshold, and the three minutes during the use of the second bin 401 is set as the time threshold. The value of the temperature and humidity Qi reflects the moisture contained in the plastic particles in the second bin 401 as a whole. The larger the value of the temperature and humidity Qi is, the more moisture the plastic particles inside the second bin 401 contain. The elastic modulus Ei of the plastic particles is expressed as the dryness of the plastic particle monomer inside the second bin 401 obtained in a single time. In addition, the temperature and humidity Qi is collected by multiple groups of temperature and humidity sensors installed on the inner wall of the second bin 401, and the elastic modulus Ei is collected by the pressure sensor 8 inside the second shell 404.

[0055] The specific collection method of the elastic modulus Ei is as follows: while the motor 1 204 drives the stirring rod 211 to stir the plastic particles in the bin body 2 401, the vacuum generator 6 is started to generate negative pressure in the shell 2 404, and the plastic particles in the bin body 2 401 are extracted by pressure, wherein the size of the through hole 2 405 is slightly larger than the plastic particles, and when the plastic particles fall to the pressure sensor 8, the cylinder 406 is started to drive the pressing plate 407 to move downward to squeeze the plastic particles, wherein the descending height of the pressing plate 407 is a preset value, and during the pressing process, the elastic modulus Ei is estimated by analyzing multiple pressure data of the pressure sensor 8, and after the detection is completed, the cylinder 406 drives the pressing plate 407 to reset, and the nozzle 408 is started to blow air into the inside of the shell 2 404, and the plastic particles on the pressure sensor 8 are blown into the collection box 409;

[0056] A closing component is also provided at the through hole 405, which is specifically used to close the through hole 405 after the plastic particles fall onto the pressure sensor 8 and the pressure sensor 8 detects the pressure data, so as to ensure that when the elastic modulus Ei is collected, only a single plastic particle is located on the pressure sensor 8. The specific form of the through hole 405 may be a baffle, etc., which are all existing technologies, and the specific structure and connection method are not described here, and are not drawn in the figure.

[0057] After receiving the temperature and humidity Qi and the elastic modulus Ei of the plastic particles, the data analysis module immediately analyzes the plastic particle data inside the second shell 404. The specific analysis steps are as follows:

[0058] The temperature and humidity Qi inside the second warehouse 401 and the elastic modulus Ei of the plastic particles within the time threshold are obtained, and the formula The raw material coefficient Vo is obtained, where a and b are respectively the proportional coefficients of temperature and humidity Qi and elastic modulus Ei, a>b>0, and Vo is represented as the raw material coefficient. The preset raw material coefficient Yo stored in the processor is retrieved for comparison and analysis with the raw material coefficient Vo;

[0059] If the raw material coefficient Vo ≥ the preset raw material coefficient Yo, it is determined that the plastic particles inside the second bin 401 are abnormal within the time threshold, and a control signal is generated. The generated control signal is sent to the signal execution module through the processor. After receiving the control signal, the signal execution module immediately controls the motor 3 413 to work.

[0060] The working principle of motor three 413 is as follows: if there is an abnormality, the motor three 413 drives the dispersion plate 411 to rotate, so that the dispersion plate 411 is tilted downward from left to right, and the plastic particles enter the shell 15; if there is no abnormality, the motor three 413 drives the dispersion plate 411 to rotate, so that the dispersion plate 411 is tilted downward from right to left, and the plastic particles enter the pushing screw 101 from the feed hopper 103 for subsequent extrusion, and then the abnormal plastic particles are transported to the bin 1 201 through the pushing screw 2 502 for secondary dehumidification, so as to adapt to a variety of dehumidification scenarios, have a wide range of applications, and further accurately control the humidity of the raw materials.

[0061] In combination with Example 1 and Example 2, it is possible to collect data on the plastic particles inside the bin body 2 401 during the use of the feeding device to obtain the overall temperature and humidity of the plastic particles and the elastic modulus of the plastic particle monomers, and to conduct a comprehensive and efficient detection of the plastic particles inside the bin body 2 401 after dehumidification, that is, to conduct a comprehensive analysis and comparison between the collected data range and the preset data range, so as to obtain relevant evaluation signals, and control the relevant components to perform compensatory operation processing accordingly, so as to cooperate with the motor 3 413 to drive the dispersion plate 411 to rotate, and classify and guide the plastic particles falling from the through hole 3 414 to prevent plastic particles with high humidity from entering the feed hopper 103 and affecting the extruder. At the same time, through the coordinated use of the stirring rod 1 210 and the fan 1 206, the plastic particles are dehumidified and dispersed to prevent them from sticking and clumping and clogging the feed port, and the multi-bin structure is used to further accurately control the humidity of the plastic particles.

[0062] The working process and principle of the present invention are as follows:

[0063] First, the raw material is transported from the feed pipe 203 to the bin body 201, and the fan 206 and the heating pipe 7 are used together to dehumidify the plastic particles. In the process of dehumidification, the stirring rod 210 is used to disperse the plastic particles, effectively avoiding the plastic particles from sticking to each other.

[0064] Furthermore, by collecting data on the plastic particles inside the bin body 2 401 during the use of the feeding device, the temperature and humidity of the plastic particles and the elastic modulus of the plastic particles are obtained, and the plastic particles inside the bin body 2 401 are comprehensively and efficiently detected after dehumidification, and the motor 3 413 is used to drive the dispersion plate 411 to rotate, the plastic particles falling from the through hole 3 414 are classified and guided, and the humidity of the plastic particles is precisely controlled, thereby effectively improving the service life of the extruder.
