Description

Technical Field

[0001] The invention relates to the technical field of nylon chip silo, and in particular to a feeding control system and a control method of nylon chip raw materials. Background Art

[0002] There are many kinds of nylon raw materials nowadays, and each different silk thread textile requires different nylon chip raw materials, and each raw material has multiple production lines. Therefore, there are multiple different silos and multiple different feeding ports in the feeding plant in the production plant. The raw materials of nylon chips cannot come into contact with oxygen, otherwise the raw materials of nylon chips will be easily oxidized, resulting in reduced spinnability and unusable.

[0003] Today's nylon raw materials are stored in very thick sealed bags to block light, and the actual condition of the raw materials in the bags cannot be seen at all. The packaging is generally very heavy, basically around 850-1000kg, which is too heavy for people to lift, and it is impossible to weigh each bag before feeding, which makes the feeding operation very troublesome. Currently, manual records are made in tables to avoid feeding errors, but errors will still occur due to manual control of the feeding.

[0004] Moreover, the storage silo at the bottom of the feeding area has a limited capacity. The actual usage in production is fixed, and the usage within a period of time can be obtained. However, in order to protect against light, the storage silo is replenished more times, and it is difficult to distinguish and record accurately. Sometimes a bag of raw materials is opened, but it is found that the silo is full and no more materials can be added, resulting in the oxidation and waste of the opened raw materials. The silo cannot be opened for inspection, which will not only allow pollutants to enter the raw materials, but also cause the raw materials in the silo to be oxidized. Therefore, the actual inventory in the silo can only be manually judged by hand-written records and a small glass window on the top of the silo, and misjudgment often occurs.

[0005] Based on this, the present invention designs a feeding control system and a control method for nylon slice raw materials to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a feeding control system and a control method for nylon chip raw materials, which do not require people to rely on experience and handwritten records, can accurately record the amount of each feeding and material data, and can also judge whether the nylon chip raw materials in the raw material bag can continue to be put into the silo, and can control the automatic valve to open or not according to the raw material situation in the silo by the controller, and can also prompt whether the feeding can be done and whether the type of raw materials matches the one in the silo through the mobile terminal. It is very convenient to use and more intelligent. Through this system, it is possible to avoid the situation where the feeding type is wrong, the total amount of feeding is wrong, and the production time of feeding is wrong, thereby ensuring the production continuity of subsequent processes and promoting product efficiency and quality.

[0007] The present invention is implemented as follows: a feeding control system for nylon slice raw materials, comprising:

[0008] The feed box is a feeding device for nylon slice raw materials. The top is provided with a feed bin cover with a feed identification code, and the bottom is provided with a feed port for the raw materials to enter the storage process. The bottom of the feed port is connected to a silo with a fixed capacity;

[0009] The feed identification code is matched with the data of the corresponding silo, and each silo has a one-to-one correspondence with a feed identification code;

[0010] An automatic valve installed on the discharge port;

[0011] The raw material bag is a sealed bag containing a fixed amount of nylon slice raw material, on which a raw material identification code is provided, and the identification code matches the data of the raw material bag in which it is located;

[0012] A mobile terminal and a controller, wherein the mobile terminal is provided with a scanning device for reading raw material identification code information, and the automatic valve, the mobile terminal and the controller are data connected;

[0013] The data matched by each raw material identification code, the data matched by the feed material identification code and the data of the silo are data information pre-entered into the controller.

[0014] Furthermore, the bin cover is a sealing cover; and the feed box is a funnel-shaped structure.

[0015] Furthermore, the automatic valve is a pneumatic solenoid valve, a flow meter is provided on the valve body of the automatic valve, a metering pump is provided at the outlet of the silo, and the metering pump is data-connected to the controller;

[0016] A low material level meter is provided at the bottom of the inner cavity of the silo, and an audible and visual alarm is provided outside the feed box. The low material level meter is connected to the audible and visual alarm, and both the low material level meter and the audible and visual alarm are connected to the controller data.

[0017] Furthermore, the data matched by the raw material identification code includes the weight and type of the raw material in the raw material bag, and the data matched by the feed material identification code includes the type, total stock and remaining stock of the raw material used for production in the silo.

[0018] Furthermore, the mobile terminal is a PDA handheld intelligent terminal.

[0019] A feeding control method for nylon slice raw materials, the control method needs to provide a feeding control system for nylon slice raw materials, comprising the following steps:

[0020] Step 1: pre-set multiple different QR codes as raw material identification codes and feed material identification codes, and enter them into the controller according to the weight and type information of the raw materials packaged in the raw material bags, match the entered raw material identification codes with the raw material types and weights, and stick the raw material identification codes with the same information matching to each raw material bag of corresponding weight and type;

[0021] Step 2: Enter the products currently produced by the production line corresponding to each feed box into the controller, then enter the corresponding raw material type, remaining space and volume in the silo into the controller, match the silo information with the feed identification code, and stick the feed identification code corresponding to the information on the outside of the corresponding feed box;

[0022] Step 3, connect the mobile terminal to the controller data;

[0023] Step 4, when feeding is required, use the mobile terminal to scan the feed identification code on the feed box to be fed, and then continue to scan the raw material identification code on the raw material bag to be fed. If the raw material identification code and the feed identification code correspond to different raw material type data, the mobile terminal continuously alarms to prompt that the raw material types do not match, and the controller controls the bin cover and the automatic valve to close;

[0024] If the raw materials are of the same type, the controller allows the bin cover and the automatic valve to open and proceeds to step 5;

[0025] Step 5: If the weight of the raw material in the raw material bag is greater than the storage weight allowed by the remaining space in the silo, the mobile terminal continues to issue an alarm prompt;

[0026] Step 6, after the raw materials in the raw material bag are added, the controller controls the automatic valve and the bin cover to close. The controller records the capacity of the raw material bag 1 of the raw material identification code scanned by the mobile terminal in step 4, and records the capacity in the remaining total amount of the silo, and transmits the information to the mobile terminal for data synchronization.

[0027] Furthermore, the raw material bags packaged with raw materials of the same type and weight use the same raw material identification code, and different raw material identification codes match different information data of weight and raw material type in the controller.

[0028] Furthermore, there are multiple mobile terminals, each of which is data-connected to the controller, and each time data is transmitted, the controller updates the data of each mobile terminal.

[0029] Furthermore, when the raw material level in the silo is lower than the position of the low level meter, the low level meter transmits information to the controller, and the controller controls the sound and light alarm to start, and notifies all connected mobile terminals that the raw materials are about to run out and to add raw materials immediately.

[0030] The beneficial effects of the present invention are as follows: 1. The present invention matches the raw material information and the nylon slice raw material information of the silo with the controller through the recognition of the raw material identification code and the feed identification code by the mobile terminal. If the types do not match, the mobile terminal will prompt that the raw material types do not match, thereby avoiding the situation where the raw material feeding types do not match;

[0031] 2. This system controls the automatic valve through the controller. If the scanned raw material type information does not match, the automatic valve will not open, ensuring that the raw materials that do not match each other will not enter the silo, avoiding cross contamination of different types of raw materials;

[0032] 3. This device records the accuracy of the feeding data of the feed box through the flow meter on the automatic valve, and counts the real-time inventory of the nylon slice raw materials in the silo through the production speed of the silo and the data of the metering pump. When the remaining space in the silo is insufficient to put the total amount of the raw material bag, the mobile terminal will also prompt to avoid the situation that the feeding silo cannot store the material, and avoid the incomplete raw materials from being exposed to oxidation in the air. This system is more intelligent and more convenient to operate;

[0033] 4. This device is equipped with a low material level meter at the bottom of the silo. If the material level in the silo is too low, the material level sound and light alarm will immediately sound an alarm so that material can be added in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] See also Figure 1 As shown, the present invention provides a technical solution: a feeding control system for nylon slice raw materials, comprising:

[0039] The feed box 2 is a feed device for nylon slice raw materials, with a feed bin cover 22 on the top, a feed identification code 24 on the top, and a feed opening 21 for the raw materials to enter the storage process at the bottom, and a silo 23 with a fixed capacity is connected to the bottom of the feed opening 21;

[0040] The feed identification code 24 matches the data of the corresponding silo 23, and each silo 23 corresponds to a feed identification code 24 one by one;

[0041] An automatic valve 3, installed on the feed opening 21;

[0042] The raw material bag 1 is a sealed bag containing a fixed amount of nylon slice raw material, on which a raw material identification code 11 is provided, and the identification code 11 matches the data of the raw material bag 1;

[0043] A mobile terminal 4 and a controller 5, wherein the mobile terminal 4 is provided with a scanning device for reading the information of the raw material identification code 11, and the automatic valve 3, the mobile terminal 4 and the controller 5 are data connected;

[0044] The data matched by each raw material identification code 11, the data matched by the feed identification code 24 and the data of the silo 23 are data information pre-entered into the controller 5. It does not require human experience and handwritten records. It can accurately record the amount of each feed in the silo 23 and the material usage data, and can also judge whether there is any remaining space in the silo 23, whether the nylon slice raw material in the raw material bag 1 can continue to be added, and the controller 5 can control whether the automatic valve 3 is opened according to the raw material situation in the silo 23, and can also prompt whether the feed can be added and whether the type of raw material matches the one in the silo 23 through the mobile terminal 4. It is very convenient to use and more intelligent. Through this system, it can avoid the situation of wrong feeding type, wrong total feeding amount, inappropriate feeding time, avoid the production of oxidized expired raw materials, ensure the production continuity of subsequent processes, and promote product efficiency and quality.

[0045] The bin cover 22 is a sealing cover; the feed box 2 is a funnel-shaped structure, which is convenient for feeding and can protect the nylon slice raw materials in the bin 23 to prevent the raw materials from contacting with air and being oxidized;

[0046] The automatic valve 3 is a pneumatic solenoid valve, and a flow meter is provided on the valve body of the automatic valve 3. A metering pump 25 is provided at the outlet of the silo 23. The metering pump 25 is data-connected to the controller 5 for easy automatic control and convenient metering of the internal stock of the silo 23.

[0047] A low material level meter 61 is provided at the bottom of the inner cavity of the silo 23, and an audible and visual alarm 6 is provided outside the feed box 2. The low material level meter 61 is connected to the audible and visual alarm 6, and both the low material level meter 61 and the audible and visual alarm 6 are data-connected to the controller 5;

[0048] The data matched by the raw material identification code 11 include the weight and type of the raw material in the raw material bag 1, and the data matched by the feed identification code 24 include the type, total stock and remaining stock of the raw material used for production in the silo 23, so as to facilitate the management of the feed in the silo 23 and avoid errors in the type of feed due to information mismatch;

[0049] The mobile terminal 4 is a PDA handheld intelligent terminal, which is a conventional device and is convenient to operate and use, and is also convenient to read data.

[0050] The feeding control method of the nylon slice raw material needs to provide a feeding control system for the nylon slice raw material, including the following steps:

[0051] Step 1, a plurality of different two-dimensional codes are used as raw material identification codes 11 and feed material identification codes 24 in advance, and the weight and type information of the raw materials packaged in the raw material bags 1 are entered into the controller 5, the entered raw material identification codes 11 are matched with the raw material types and weights, and the raw material identification codes 11 with the same information matching are adhered to each raw material bag 1 of the corresponding weight and type;

[0052] Step 2, input the products currently produced by the production line corresponding to each feed box 2 into the controller 5, then input the corresponding raw material type, remaining space and volume in the silo 23 into the controller 5, and match the information of the silo 23 with the feed identification code 24, and stick the feed identification code 24 corresponding to the information on the outside of the corresponding feed box 2;

[0053] Step 3, data connection between the mobile terminal 4 and the controller 5;

[0054] Step 4, when feeding is required, use the mobile terminal 4 to scan the feed identification code 24 on the feed box 2 to be fed, and then continue to scan the raw material identification code 11 on the raw material bag 1 to be fed. If the raw material type data corresponding to the raw material identification code 11 and the feed identification code 24 are different, the mobile terminal 4 continuously alarms to prompt that the raw material types do not match, and the controller 5 controls the bin cover 22 and the automatic valve 3 to close;

[0055] If the types of raw materials are the same, the controller 5 allows the bin cover 22 and the automatic valve 3 to open, and enters step 5;

[0056] Step 5, if the weight of the raw material in the raw material bag 1 is greater than the storage weight allowed by the remaining space in the silo 23, the mobile terminal 4 continues to issue an alarm prompt;

[0057] Step 6, the raw materials in the raw material bag 1 are added, and the automatic valve 3 and the bin cover 22 are closed by the controller 5. The controller 5 records the capacity of the raw material bag 1 of the raw material identification code 11 scanned by the mobile terminal 4 in step 4, and records the capacity in the remaining total amount of the silo 23, and transmits the information to the mobile terminal 4 for data synchronization.

[0058] The raw material bags 1 packaged with raw materials of the same type and the same weight use the same raw material identification code 11. Different raw material identification codes 11 match different information data of weight and raw material type in the controller 5. In this way, fewer types of QR codes can be used as raw material identification codes 11, and the raw material bags 1 can be classified according to type and weight, which is convenient to use. However, the feed identification code 24 cannot be classified. The inventory and production speed of each different silo 23 are different, and the feed box 2 of each different silo 23 must use a different feed identification code 24.

[0059] There are multiple mobile terminals 4, each of which is data-connected to the controller 5. Each time data is transmitted, the controller 5 updates the data of each mobile terminal 4, which is convenient for multiple people to use and view, and also convenient for monitoring personnel to spot check and verify the raw materials and production process;

[0060] When the raw material level in the silo 23 is lower than the position of the low material level meter 61, the low material level meter 61 transmits the information to the controller 5, and the controller 5 starts the sound and light alarm 6 and notifies all connected mobile terminals 4 that the raw material is about to run out and to add raw material immediately.

[0061] In a specific embodiment of the present invention:

[0062] The embodiment of the present invention provides a feeding control system and a control method for nylon slice raw materials. The technical problems solved by the present invention are: 1. The textile raw materials of nylon slices are stored in a light-shielding sealed bag to isolate oxygen and vacuum, and a spinning factory generally has multiple production lines, and it is possible that the raw materials produced by each production line are different, and the capacity of the silo 23 of each production line is also different, which brings great difficulties to the feeding. The types of raw materials are also various, and the information on the raw material bag 1 is generally not particularly obvious, and needs to be carefully searched, which brings very cumbersome identification steps to the feeding, which is very troublesome. Such a situation will lead to the wrong type of nylon slice raw materials;

[0063] 2. When feeding nylon slice raw materials, the raw material bags have various specifications of raw materials such as 800kg, 850kg or 1000kg, and are generally fed one bag at a time. When the last few bags are fed, it is difficult to accurately grasp the remaining space in the silo 23. Generally, a very small glass window on the top of the silo is used to manually judge the actual stock in the silo, and misjudgment often occurs. There will be insufficient remaining space in the silo 23, and the capacity of the raw material bag 1 is too large, resulting in the inability to feed, and the raw materials remain in the raw material bag 1. In this way, the remaining raw materials will be quickly oxidized and become waste, resulting in loss.

[0064] The technical effects achieved are as follows: 1. The present invention matches the raw material information and the nylon slice raw material information of the silo 23 with the controller 5 by identifying the raw material identification code 11 and the feed identification code 24 through the mobile terminal 4. If the types do not match, the mobile terminal 4 will prompt that the raw material types do not match, thereby avoiding the situation where the raw material feeding types do not match;

[0065] 2. The system controls the automatic valve 3 through the controller 5. If the scanned raw material type information does not match, the automatic valve 3 will not open, ensuring that the raw materials that do not match each other will not enter the silo 23, avoiding the cross contamination of different types of raw materials;

[0066] 3. The device records the accuracy of the feeding data of the feed box 2 through the flow meter on the automatic valve 3, and counts the real-time inventory of the nylon slice raw materials in the silo 23 through the production speed of the silo 23 and the data of the metering pump 25. When the remaining space in the silo 23 is insufficient to put the total amount in the raw material bag 1 identified by the scan code, the mobile terminal 4 will also give a prompt to avoid the situation where the feeding silo 23 cannot store the materials, and to avoid the incompletely put raw materials from being exposed to oxidation in the air. The system is more intelligent and easier to operate.

[0067] The technical solution in the embodiment of the present invention is to solve the above problems, and the overall idea is as follows:

[0068] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0069] When making the present invention, first make a sealed feed box 2, the feed box 2 needs to be a funnel-shaped structure, the capacity of the feed box 2 is not large, generally less than the capacity of 200kg nylon chips, and it only has a feeding function, and make a bin cover 22 on the top of the feed box 2, the bin cover 22 can be a manual or electrically controlled bin door that opens and closes automatically, and is linked controlled by the controller 5. Preferably, the bin cover 22 is an automatic electrically controlled bin door, that is, an automatic closer plus an electromagnetic lock, the electromagnetic lock is controlled by the controller 5, it can be automatically closed, but cannot be automatically opened, it is a common device for electromagnetic locks, but the bin cover 22 of the device needs to be sealed and covered with the feed box 2, and then a feed opening 21 is provided at the bottom of the feed box 2, and an automatic valve 3 is installed on the feed opening 21, the automatic valve 3 is a pneumatic control valve, and the opening is controlled by the controller 5 Or closed, the bottom outlet of the discharge port 21 is sealed and connected to the silo 23, which is a production silo used in production and is directly connected to the production line, rather than for storage. The nylon slice raw material in the silo 23 is connected to the production line pipeline, and the raw material is continuously transported by the metering pump 25 at the bottom. The nylon slice raw material is transported to the subsequent raw material mixing pipeline by the metering pump 25, and then squeezed into the screw conveyor for melting. The metering pump 25 can accurately measure the raw material leaving the silo 23; because the silo 23 is very large in size, the general feed box 2 generally needs to be installed on the ground for the convenience of feeding, so in conventional factory building construction, the feed box 2 is installed on the bottom surface of the floor, and the silo 2 is generally very large in size, occupying the height of the entire floor, and the silo 23 needs to be installed and docked on the floor below the feed box 2;

[0070] It is also necessary to paste the feed identification code 24 on the outside of the feed box 2. In the production plant, the feed identification code 24 must be pasted on the outer wall of each feed box 2 to ensure that the feed identification code 24 is clearly visible and each feed identification code 24 is different. The feed identification code 24 is a two-dimensional code.

[0071] A raw material bag 1 is made. The raw material bag 1 is a packaging bag for the raw materials. Each raw material bag 1 is light-shielded and sealed to ensure that the nylon slice raw materials inside will not come into contact with the outside air and will not be exposed to direct sunlight. A raw material identification code 11 is pasted on the outside. The raw material identification code 11 is also a two-dimensional code, and both the raw material identification code 11 and the feed identification code 24 have specific information. The data matched by the raw material identification code 11 on the raw material bag 1 include the capacity, type and production time of the raw material bag 1. The data matched by the feed identification code 24 include the last feeding time of the silo 23, the type of raw materials used for production, the total capacity and the remaining capacity. In this way, all the required data are recorded in the controller 5. The controller 5 manages and matches the data to control the silo cover 22 and the automatic valve 3 to open or close.

[0072] It is also necessary to use a mobile terminal 4, which is a PDA handheld terminal, which is a common technical means of this type of identification system. By scanning and reading the raw material identification code 11 and the feed identification code 24 through the mobile terminal 4, it is possible to timely check whether the information of the raw material bag 1 matches the feed box 2, and whether the type of nylon raw material corresponds. If not, the system controls the automatic valve 3 not to open, and the bin cover 22 not to open. If the raw material types match, the bin cover 22 can be opened, and the automatic valve 3 can also be opened; if the capacity of the raw material bag 1 is greater than the remaining capacity in the bin 22, the mobile terminal 4 will continue to prompt an alarm, but will not prevent the bin cover 22 and the automatic valve 3 from opening;

[0073] A controller 5 is installed outside the feed box 2. The controller 5 is a computer-controlled PLC controller. When the raw material level in the silo 23 is lower than the position of the low level meter 61, the low level meter 61 transmits information to the controller 5. The controller 5 controls the sound and light alarm 6 to start, and notifies all connected mobile terminals 4 that the raw materials are about to run out and to add raw materials immediately. The low level meter 61 and the sound and light alarm 6 are used to give the staff a final reminder.

[0074] When the present invention is used, the following steps are required:

[0075] Step 1: Use multiple different QR codes as raw material identification codes 11 and feed identification codes 24 in advance, and enter and match the raw material bag information by batch. The same type of raw materials in the same batch use the same raw material identification code 11. The raw material identification code 11 matches the capacity and the type of raw materials. Enter the data matching the raw material identification code 11 into the controller 5. Different capacities and different types of raw materials require different QR code patterns to be replaced as new and different raw material identification codes 11. The raw material identification code 11 matching the data is pasted on each raw material bag 1 of the corresponding weight and raw material type.

[0076] Step 2: Enter the product types currently produced by each feed box 2 and the inventory data in the silo 23 into the controller 5, then enter the corresponding raw material types, remaining space and volume into the controller 5, and match the data with the corresponding feed identification code 24, and stick the corresponding feed identification code 24 on the outside of the feed box 2;

[0077] Step 3, each PDA mobile terminal 4 is connected to the controller 5 by data;

[0078] Step 4: When feeding is required, the mobile terminal 4 scans the feed identification code 24 on the feed box 2 to be fed, and then continues to scan the raw material identification code 11 on the raw material bag 1 to be fed. If the raw material type data corresponding to the raw material identification code 11 and the feed identification code 24 are different, the controller 5 controls the bin cover 22 and the automatic valve 3 to close, and waits for the mobile terminal 4 to rescan the new raw material bag 1;

[0079] If the types of raw materials are the same, the controller 5 allows the bin cover 22 and the automatic valve 3 to open, and then proceeds to step 5;

[0080] Step 5: If the volume of the raw material bag 1 is greater than the remaining volume in the silo 23, the mobile terminal 4 continues to issue an alarm prompt;

[0081] Step 6, after the raw materials in the raw material bag 1 are added, the controller 5 is manually operated through the mobile terminal 4 to control the automatic valve 3 and the bin cover 22 to close. The controller 5 records the capacity of the raw material bag 1 of the raw material identification code 11 scanned before, and records the capacity in the remaining total amount of the silo 23. The remaining space stock of the silo 23 before adding the raw materials is subtracted from the amount of raw materials scanned and added to the raw material bag 1, and the time point when the adding is completed is recorded.

[0082] Although the specific implementation modes of the present invention are described above, those skilled in the art should understand that the specific implementation modes described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.

A feeding control method for nylon chip raw materials, characterized in that: The feeding control method of the nylon chip raw material needs to provide a feeding control system of the nylon chip raw material as claimed in claim 1, comprising the following steps: Step 1, a plurality of different two-dimensional codes are used as raw material identification codes (11) and feed material identification codes (24) in advance, and the weight and type information of the raw materials packaged in the raw material bags (1) are entered into the controller (5), the entered raw material identification codes (11) are matched with the raw material types and weights, and the raw material identification codes (11) with the same information matching are adhered to each raw material bag (1) of the corresponding weight and type; Step 2, the products currently produced by the production line corresponding to each feed box (2) are entered into the controller (5), and then the type of raw materials, remaining space and volume corresponding to the material bin (23) are entered into the controller (5), and the information of the material bin (23) is matched with the feed identification code (24), and the feed identification code (24) corresponding to the information is pasted on the outside of the corresponding feed box (2); Step 3, connecting the mobile terminal (4) to the controller (5) by data connection; Step 4, when it is necessary to feed materials, use the mobile terminal (4) to scan the feed identification code (24) on the feed box (2) to be fed, and then continue to scan the raw material identification code (11) on the raw material bag (1) to be fed. If the raw material type data corresponding to the raw material identification code (11) and the feed identification code (24) are different, the mobile terminal (4) will continuously alarm to prompt that the raw material types do not match, and the controller (5) controls the bin cover (22) and the automatic valve (3) to close; If the types of raw materials are the same, the controller (5) allows the bin cover (22) and the automatic valve (3) to open, and enters step 5; Step 5, if the weight of the raw materials in the raw material bag (1) is greater than the weight allowed to be stored in the remaining space in the silo (23), the mobile terminal (4) continues to issue an alarm prompt; In step 6, the raw materials in the raw material bag (1) are added, and the automatic valve (3) and the bin cover (22) are closed by the controller (5). The controller (5) records the capacity of the raw material bag 1 of the raw material identification code (11) scanned by the mobile terminal (4) in step 4, and records the capacity in the remaining total amount of the bin (23), and transmits the information to the mobile terminal (4) for data synchronization.

5. The feeding control method of nylon chip raw material according to claim 4 is characterized in that: The raw material bags (1) packaged with raw materials of the same type and weight use the same raw material identification code (11), and different raw material identification codes (11) match different weight and raw material type information data in the controller (5).

6. The feeding control method of nylon chip raw material according to claim 4 is characterized in that: There are a plurality of mobile terminals (4), each of which is data-connected to a controller (5). Each time data is transmitted, the controller (5) updates the data of each mobile terminal (4).

7. The feeding control method of nylon chip raw material according to claim 4 is characterized in that: When the raw material level in the silo (23) is lower than the position of the low material level meter (61), the low material level meter (61) transmits information to the controller (5), and the controller (5) controls the sound and light alarm (6) to start, and notifies all connected mobile terminals (4) that the raw material is about to run out and to add raw material immediately.
