Description

Technical Field

[0001] The invention relates to mixing equipment for plastic granulation processing, belonging to the technical field of plastic granulation processing. Background Art

[0002] Mixing equipment for plastic granulation is a kind of equipment specially used for efficiently mixing various plastic materials and additives, which is widely used in the production process of plastic products. The main function of this equipment is to evenly mix different plastic particles and additives to ensure the quality and performance of the final product. Generally, mixing equipment for plastic granulation includes a stirrer, a feed port, a discharge port and a control system.

[0003] Existing mixing equipment for plastic granulation processing is often used to manufacture special composite materials. The production of these composite materials requires the mixing of multiple base materials to obtain specific physical, chemical and mechanical properties. However, the equipment usually has a limited number of feed ports connected to the batching end, which poses certain challenges for the preparation of multiple small batches of special composite materials.

[0004] Since each special composite material usually requires a different formula and material combination, it is necessary to frequently replace various main and auxiliary materials when producing different composite materials. When different materials are replaced and added, they need to be carried out through a limited number of feed ports. Due to the limitation of the number of feed ports, it is difficult for the equipment to process multiple raw materials at the same time, and it is impossible to efficiently cope with complex formula requirements that require more types of materials than the number of its feed ports.

[0005] When production needs involve multiple small batches of special materials, the existing equipment is cumbersome in material replacement and process adjustment, which limits production flexibility and efficiency.

[0006] Therefore, the research purpose of the present invention is to design a mixing equipment for plastic granulation processing with high flexibility and automatic control function to solve the cumbersomeness and efficiency problems of current equipment in producing a variety of small batches of special composite materials. The mixing equipment for plastic granulation processing is the research purpose of the present invention. Summary of the invention

[0021] When the cartridge is in an installed state, the second conductive terminal fits the third conductive terminal.

[0022] As a further improvement, the material barrel is located at one end of the mixing container and connected to an external material pipe, the end of the material pipe is sleeved with an auxiliary pipe, and the outer ring surface of the auxiliary pipe is fixedly mounted with a first bearing;

[0023] A first auxiliary connecting ring is welded to one end of the barrel facing the auxiliary connecting pipe, and a first guide groove is provided on the inner side of the first auxiliary connecting ring;

[0034] The beneficial effects of the present invention are:

[0035] The present invention provides a plurality of groups of pluggable barrels and discharge plates, so that the equipment can quickly adjust the number of barrels according to different production requirements, thereby improving the flexibility of the equipment.

[0036] Through the pluggable barrel design, the equipment can quickly increase or decrease the number of barrels used according to production needs, and flexibly adjust the production configuration. The combination of the discharge plate and the second drive motor enables the barrel to be opened or closed accurately, ensuring that the required materials are put into the mixing container as needed.

[0037] The problem of the limited number of feed ports in existing equipment has been solved, greatly improving the equipment's ability to handle a variety of materials. The cumbersome steps in the material replacement process have been eliminated, allowing the equipment to efficiently and easily prepare a variety of small batches of special composite materials. The limitation that traditional equipment cannot effectively handle special composite materials that require more than the number of feed ports has been solved, broadening the application range of the equipment.

[0038] Since the traditional system may have problems of cumbersome operation and unstable installation when connecting and repairing the barrel and the drive motor, the present invention sets a second drive motor with a double output rod design, sets output rods on both sides, and winds the first traction line to control the opening and closing of the discharge plate more stably.

[0039] By providing a removable cover plate and a side groove, the cover plate can be easily removed through the side groove, which facilitates access to and repair of the second drive motor, thereby increasing the convenience of maintenance.

[0040] Since the power supply connection of the drive motor is complicated, it may cause maintenance difficulties or poor power supply contact. The present invention realizes a more reliable and safe power supply connection by setting the first, second and third conductive terminals, connecting with the external power line, and enhancing the power supply stability of the system.

[0041] Since the barrel may have the problem of inaccurate positioning when connected to the mixing container, the present invention not only enhances the adaptability of the device but also simplifies the process of connection and disassembly by setting a multi-level connection auxiliary structure and connecting the external material pipe and the auxiliary pipe. The coordination of the bearing and the guide groove ensures the stability and flexibility of the connection.

[0042] The invention provides an improved positioning component and utilizes the structure of a plug-in block and a spring to ensure that the barrel can be stably connected to the mixing container under any high-speed operation condition.

[0043] Due to the lack of clear working status prompts, it is difficult to judge the current system status during operation. The present invention provides a prompt light, which is electrically connected to the control module to clearly indicate the current barrel status and provide immediate operation guidance.

DETAILED DESCRIPTION

[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0056] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0057] In the existing mixing equipment for plastic granulation processing, since the production of special composite materials requires the mixing of multiple basic materials to obtain specific physical, chemical and mechanical properties, and the feed ports usually connected to the batching end are relatively limited, it is relatively cumbersome to replace the multiple main and auxiliary materials when preparing a variety of small batches of special composite materials, and the equipment cannot prepare special composite materials whose number of material types exceeds the number of its feed ports.

[0058] Reference Figure 1-8 As shown, a mixing device for plastic granulation processing comprises:

[0059] A mixing container 1, a plurality of feeding components arranged on one side above the mixing container 1, a stirring component 5 arranged inside the mixing container 1, a first driving motor 2 driving the stirring component 5, and a control module 3;

[0060] The feed assembly comprises:

[0061] A barrel 4 inserted into the side of the mixing container 1, a discharge plate 41 rotatably installed under the barrel 4, and a second drive motor 42 driving the discharge plate 41 to rotate, a positioning component 6 is provided at the insertion end of the barrel 4, and the positioning component 6 is embedded in the inner wall of the mixing container 1, and the first drive motor 2 and the second drive motor 42 are electrically connected to the control module 3;

[0062] The barrel 4 corresponding to the amount of material is laterally inserted into the mixing container 1, and the barrel 4 is positioned and fixed by the cooperation between the positioning component 6 and the inner wall of the mixing container 1;

[0063] The opening / closing state of the corresponding barrel 4 is controlled by the cooperation between the second driving motor 42 and the discharge plate 41;

[0064] When it is turned on, the material in the barrel 4 is input into the mixing container 1, and the control module 3 cooperates with the first drive motor 2 and the stirring component 5 to mix multiple materials.

[0065] The discharge port at the bottom of the mixing container 1 is connected to the feed port at the top of the granulator 9 .

[0066] A plurality of holes are provided on the side of the mixing container 1. When the holes are not in use, the holes are blocked by inserting a blocking plate. In this embodiment, the holes are arranged in a rectangular shape.

[0067] Usage scenario 1: When carrying out large-scale production of a single material, select a suitable barrel 4 and insert it sideways into the hole of the mixing container 1.

[0068] The corresponding discharge plate 41 is opened by the control module 3 to continuously supply the material into the mixing container 1 .

[0069] The first drive motor 2 and the stirring assembly 5 are started to perform efficient mixing.

[0070] After being mixed evenly, the material enters the granulator 9 through the discharge port below the mixing container 1 to complete the granulation.

[0071] In this scenario, the equipment simplifies operation and ensures continuous and efficient production. Due to the precise control of the control module 3, the consistency of material delivery and mixing can be guaranteed.

[0072] Usage scenario 2: To meet the needs of small batch production, multiple barrels 4 can be selected at the same time, and the optimal number of holes can be inserted according to the required material type and quantity.

[0073] Through programming of the control module 3, the discharge of each barrel 4 is accurately controlled so as to mix a variety of materials.

[0074] Change the order of inserting and batching the barrel 4, and make full use of the modular design for rapid material replacement.

[0075] The equipment provides flexible multi-barrel 4-parallel working capabilities, which can quickly switch materials and reduce downtime. It has higher flexibility, adapts to various small batch production needs, and helps to produce personalized or customized products.

[0076] Usage scenario three: When used for the research and development of new materials in the laboratory, the barrel 4 can be added or subtracted at any time according to the experimental formula to explore the characteristics of different materials.

[0077] Through precise control by programming the control module 3, the barrel 4 is opened and closed at different time periods, different ratios and combinations are explored, and material properties are verified.

[0078] The modular and programmable design of the equipment makes it an ideal choice for researching new formulations. The flexible barrel 4 configuration and high-precision control system ensure the repeatability and accuracy of the experiment.

[0079] Compared with the prior art, the pluggable barrel 4 and the plugging plate can quickly adjust the equipment according to different production requirements, which improves the flexibility of the equipment. It solves the problem of limited feed ports of the existing equipment, and can process a variety of materials at the same time, reducing the cumbersome steps of material replacement. By cooperating with the control module 3, the discharge of each barrel 4 can be accurately controlled to ensure accurate ratio and improve the consistency and quality of the product.

[0080] Its main feature is that during the switching process between different materials, through efficient design and automatic operation, it reduces downtime and improves production efficiency.

[0081] In order to achieve rapid mixing of multiple materials, the stirring assembly 5 includes a rod 51 inserted into the output end of the first driving motor 2, a set of locking plates installed in parallel on the outer annular surface of the rod 51, and a stirring blade 52 is spirally arranged between the two locking plates. The outer side of the stirring blade 52 is spaced 2-3 cm from the barrel 4. This distance setting can avoid the contact between the stirring blade 52 and the inner wall of the barrel 4, and at the same time can apply a larger stirring force to the material.

[0082] For the convenience of distinction, the locking piece close to the upper side of the agitating piece 52 is defined as a first locking piece 53 , and the locking piece close to the lower side of the agitating piece 52 is defined as a second locking piece 54 .

[0083] To prevent the barrel 4 from interfering with the rod 51 when the rod 51 rotates, the first locking piece 53 is located below the lowest barrel 4, and the rod 51 is offset from the barrel 4 from top to bottom, thereby preventing the barrel 4 from interfering with the rod 51 when it rotates.

[0084] In order to further disperse the material released from the barrel 4, an arc plate is provided above the first locking piece 53, and the material from top to bottom is quickly dispersed by the rotating arc plate.

[0085] It also includes a support frame 55 fixedly mounted on the bottom of the mixing container 1, and a bearing embedded in the middle of the upper part of the support frame 55, and the lower end of the rod 51 is inserted into the bearing.

[0086] Among them, the design of the rod 51 and the locking piece, the rod 51 is driven by the first driving motor 2 to provide stirring rotation power.

[0087] The first locking piece 53 and the second locking piece 54 are installed in parallel on the outer annular surface of the rod 51. Their functions are to fix the stirring blade 52 and help stabilize the balance of the stirring blade 52 during rotation.

[0088] The stirring blade 52, which is spirally arranged between the locking blades, is used to stir and mix the materials in the barrel 4. Its design optimizes the uniformity and efficiency of stirring.

[0089] Through efficient mixing, the spiral design of the rotary stirring blade 52 helps to generate a strong material flow during stirring, ensuring that a variety of materials are evenly mixed in a short time.

[0090] The non-interference design avoids the interference of the barrel 4 with the rod 51 when the rod 51 rotates through the layout of the height of the first locking piece 53. This non-interference design makes the operation of the equipment more stable and reliable.

[0091] The arc plate is fixed on the top of the first locking piece 53 by welding, and the plate is installed on the top of the first locking piece 53 to quickly disperse the materials when they are released from the barrel 4. This component evenly disperses the falling materials through rotational motion to optimize the distribution of the materials in the container.

[0092] The rotation of the arc plate allows the falling materials to be preliminarily dispersed before falling into the mixing container 1, reducing the aggregation of materials and thus improving the mixing efficiency. At the same time, the uniformity is enhanced. Before the mixing starts, the function of the arc plate to disperse the materials makes the initial material distribution more uniform, further improving the overall mixing effect.

[0093] In addition, a support frame 55, which is installed at the bottom of the mixing container 1, provides stability to the overall structure.

[0094] The bearing is embedded in the middle of the upper part of the support frame 55. The bearing supports the lower end of the rod 51, providing stable support for the rotation of the rod 51, so that it can maintain stable rotational motion. The combination of the support frame 55 and the bearing provides a stable operating platform for the rod 51, reducing the decrease in mixing efficiency caused by vibration or instability. By providing stable rotation support, the bearing reduces the friction between the rod 51 and the support frame 55, prolongs the service life of the equipment, and reduces maintenance requirements.

[0095] To achieve control operation of the discharge plate 41 , in this embodiment, output rods 421 are provided on both sides of the second drive motor 42 , and a first traction line 422 is wound around the outer annular surface of the output rod 421 , and the end of the first traction line is fixedly connected to the discharge plate 41 .

[0096] Among them, a group of the discharge plates 41 are provided, and a connecting ring 411 is configured above the discharge plate 41 at the positions corresponding to the two output rods 421 , and the first traction line 422 is tied and fixed on the connecting ring 411 .

[0097] The second driving motor 42 is a bidirectional forward and reverse motor, that is, output rods 421 are provided at both ends, and when the second driving motor 42 rotates forward, the discharge plate 41 can be released to open the barrel 4 and discharge the material inside the barrel 4.

[0098] When the driving motor is reversed, the first pulling line 422 can be reeled in to cooperate with the connecting ring 411 to retract the discharge plate 41 to reset the material inside the barrel 4, thereby blocking the discharge of the material.

[0099] Among them, the output rod 421 and the traction line are set, and the output rod 421 is located on both sides of the second drive motor 42, and is a key power transmission device that converts the rotational motion of the motor into traction motion. The first traction line 422 is wound on the outer ring surface of the output rod 421, and the opening and closing control of the discharge plate 41 is realized by its retraction and extension.

[0100] The connecting ring 411 structure is arranged above the discharge plate 41, and is connected and hung with the first traction line 422, serving as a part of the traction line force transmission mechanism.

[0101] The second drive motor 42 is a bidirectional forward and reverse motor, which is a motor that can rotate in two directions. This design enables it to achieve more complex and flexible operations. Specifically, the characteristics and advantages of the bidirectional forward and reverse motor include: being able to achieve forward and reverse rotation through a simple control signal. This is achieved by changing the direction of the current or the control logic inside the motor. By controlling the direction of rotation of the motor, the device can achieve a variety of functions, usually only by modifying the power wiring or using the control module 3 for signal switching. The bidirectional forward and reverse motor is usually provided with output rods 421 on both sides, which allows it to perform different mechanical actions in rotation in different directions, such as driving the traction line to open or close the discharge plate 41.

[0102] The bidirectional forward and reverse motor can realize precise control over the opening and closing process of the discharge plate 41, thereby ensuring the accuracy of each discharge, and cooperate with the barrel 4 to make the material discharge stable and controllable.

[0103] This design reduces the complex mechanical transmission structure and relies on a simple traction principle to achieve control, which increases the stability and reliability of the structure and reduces the failure rate.

[0104] Due to the simple structure, the installation and maintenance of the traction line and the connecting ring 411 are more convenient, which reduces the maintenance cost and time of the equipment.

[0105] To facilitate installation / maintenance, a side groove 43 and a cover plate 44 covering the side groove 43 are provided on the side of the barrel 4 corresponding to the position of the second driving motor 42;

[0106] A receiving plate 45 is provided on the inner side surface of the barrel 4 at a position corresponding to the side groove 43, and the second driving motor 42 is fixedly abutted on the receiving plate 45;

[0107] The cover plate 44 is removed, and the second drive motor 42 is exposed through the side groove 43 for installation and maintenance.

[0108] The cover plate 44 is installed and fixed by bolts.

[0109] A first conductive terminal 423 is disposed on the side of the second driving motor 42, a second conductive terminal 424 is disposed on the cover plate 44 at a position corresponding to the first conductive terminal 423, and a third conductive terminal 425 is disposed inside the mixing container 1 at a position corresponding to the second conductive terminal 424, and the third conductive terminal 425 is connected to an external power line;

[0110] When the second driving motor 42 is in the installed state, the first conductive terminal 423 fits with the second conductive terminal 424;

[0111] When the cartridge 4 is in the installed state, the second conductive terminal 424 fits with the third conductive terminal 425 .

[0112] By using multiple conductive terminals (first, second and third conductive terminals 425), it is ensured that the motor, cover plate 44 and mixing container 1 can achieve power and signal connection through physical contact. This modular connection method makes assembly and disassembly easier and is also convenient for maintenance and replacement.

[0113] The design of the conductive terminal connects the motor to the external power line, effectively reducing the need for wiring inside the device. This reduces the possibility of wire clutter and the risk of wiring errors.

[0114] Although the design allows the motor to conduct signals through the wireless unit, it still supports conducting signals through the power line. This flexibility allows the device to adapt to multiple signal transmission schemes in different operating environments to improve reliability.

[0115] The conductive terminals physically separate the independence between different components, preventing power from being applied when incorrectly installed, thus increasing system safety.

[0116] Due to the direct physical contact between the conductive terminals, a stable and reliable power and signal channel connection is achieved, reducing the risk of poor contact and ensuring smooth operation of the equipment.

[0117] At the same time, this structural design is highly adaptable and can support future system expansion, such as switching from wired connection to wireless unit connection, or adding additional functional modules.

[0118] And by reducing the need for additional wiring and simplifying the design, material costs and production complexity can be reduced, while reducing labor costs during installation and removal.

[0119] It should be emphasized that the second driving motor 42 can be equipped with a wireless unit, and can also transmit signals through a power line. In this embodiment, the second driving motor 42 transmits signals through a power line.

[0120] In order to facilitate the feeding support of the barrel 4 and the installation, an external material pipe 46 is connected to one end of the barrel 4 located at the mixing container 1, and an auxiliary pipe 47 is sleeved on the end of the material pipe 46. A first bearing 471 is fixedly installed on the outer ring surface of the auxiliary pipe 47;

[0121] A first auxiliary connecting ring 48 is welded to one end of the barrel 4 facing the auxiliary connecting pipe 47, and a first guide groove 481 is provided on the inner side of the first auxiliary connecting ring 48;

[0122] The first auxiliary connecting ring 48 is a fixed ring welded on the barrel 4. A second auxiliary connecting ring 49 is rotatably arranged between the first auxiliary connecting ring 48 and the auxiliary connecting pipe 47. A second guide groove 492 is arranged on the inner side of the second auxiliary connecting ring 49. A second bearing 491 is fixedly installed toward one end of the first auxiliary connecting ring 48.

[0123] Wherein, the first bearing 471 matches with the second guide groove 492, and the second bearing 491 matches with the first guide groove 481;

[0124] The arrangement of multiple layers of auxiliary rings and bearings ensures that the connection between the barrel 4 and the external material pipe 46 is more stable, which can effectively prevent material leakage and joint loosening.

[0125] By using paired guides and bearings, the design allows a certain degree of rotation or adjustment while maintaining a seal. This is directly helpful for handling mechanical parts that require rotational action or adjusting the angle of a connection.

[0126] Using bearings to support rotating parts helps reduce direct mechanical friction, slows down wear rates, and thus extends the life of the system.

[0127] During installation, ensure that the first bearing 471 is embedded in the second auxiliary ring 49, and at the same time, the second bearing 491 is embedded in the first auxiliary ring 48. This nested arrangement ensures the stability of the structure.

[0128] During maintenance, the bearing can be easily replaced and lubricated by taking advantage of its disassembly. Separate the auxiliary ring first and then perform the necessary maintenance operations.

[0129] The positioning assembly 6 includes a first plug-in block 61 disposed at one end of the insertion end of the barrel 4, and a first plug-in hole 62 matched with the first plug-in block 61. The first plug-in hole 62 is disposed on the inner wall of the mixing container 1, and the barrel 4 is positioned by the cooperation between the first plug-in block 61 and the first plug-in hole 62;

[0130] The positioning assembly 6 further includes a through hole 63 which is arranged perpendicular to the axis and passes through the first plug-in block 61, a second plug-in block 64 which is inserted into the through hole 63, and a spring 66 is arranged between the two second plug-in blocks 64;

[0131] A second plug hole 65 matching the second plug block 64, wherein the second plug hole 65 is arranged on the inner wall of the first plug hole 62;

[0132] The two second plug-in blocks 64 are supported by the springs 66 to partially extend out of the first plug-in block 61 and are inserted into the second plug-in holes 65 to fix the barrel 4 .

[0133] In order to release the cooperation between the second plug-in block 64 and the second plug-in hole 65, a second pulling line 67 is provided which passes through the spring 66 and connects the two second plug-in blocks 64. The second pulling line 67 passes through the first auxiliary ring 48 and is fixed on the side of the second auxiliary ring 49.

[0134] The second auxiliary ring 49 is rotated to cooperate with the second pulling line 67 to pull the two second plug-in blocks 64 out of the second plug-in holes 65 .

[0135] As the second auxiliary ring 49 is rotated and the second traction line 67 is tightened, the distance between the two second plug-in blocks 64 is reduced, and then they are disengaged from the second plug-in holes 65, and the spring 66 is compressed. When the second auxiliary ring 49 is released, the spring 66 pushes the two second plug-in blocks 64 to reset.

[0136] When installing the barrel 4, only the insertion action is required. The outer surfaces of the two second plug-in blocks 64 are smooth, and they can be directly deformed and adapted under the pressure of the holes, so that the first plug-in block 61 is directly inserted into the first plug-in hole 62. At the same time, the second plug-in block 64 is directly inserted into the second plug-in hole 65 under the action of the spring 66, and the positioning and fixing operation can be quickly completed.

[0137] When the barrel 4 needs to be removed, the second auxiliary ring 49 is rotated to cooperate with the second traction line 67 to pull the two second plug-in blocks 64 out of the second plug-in holes 65, and then the barrel 4 is pulled out from the hole, and other barrels 4 can be inserted at this time.

[0138] The middle parts of both sides of the long sides of the barrel 4 extend toward the upper middle part to form an angle part 7, and the angle part 7 cooperates with the holes on the side of the mixing container 1 to fix the discharge of the barrel 4 toward the downward direction.

[0139] The angled portion 7 and the barrel 4 form a water drop structure with a sharp top and a smooth bottom in cross section.

[0140] In order to facilitate the judgment of the working condition of the barrel 4 , a warning light 8 is further included, which is arranged at one end of the barrel 4 facing the first auxiliary ring 48 , and the warning light 8 is electrically connected to the control module 3 .

[0141] Among them, the prompt light 8 is provided with two lamp beads of different colors, which are named as the first lamp bead and the second lamp bead for convenient distinction. When the barrel 4 enters the power-on state, the first lamp bead enters the power-on state by default, indicating that it is installed and inserted in place, and the second drive motor 42 is in the power-on state, and the normal feeding state can be entered.

[0142] When the barrel 4 is finished unloading, the control module 3 disconnects the power supply of the first lamp bead and switches the power supply of the second lamp bead to the power supply state, which prompts the outside that the barrel 4 has finished unloading. If a new barrel 4 is needed, the barrel 4 can be replaced.

[0143] It should be emphasized that the start of material discharge from the barrel 4 is determined by the open state of the discharge plate 41 in the feed assembly, while the completion of material discharge is determined by the closed state of the discharge plate 41.

[0144] The addition of the prompt light 8 enables the operator to confirm the working state of the device through simple visual prompts. Different colored lamp beads represent different states, which are easy to identify.

[0145] Clear visual prompts can effectively prevent equipment failure or safety hazards caused by misoperation. For example, only operate when the first lamp is on to ensure that the equipment is in the correct working state. With clear visual signal guidance, operators can replace the barrel 4 or perform other operations in time, reducing the possibility of human error.

[0146] When the equipment starts working, the barrel 4 is in a powered-on state, and the first lamp bead lights up, indicating that the barrel 4 has been correctly installed. At this time, the personnel can start or continue the operation without worry.

[0147] During the unloading process, the control module 3 monitors the state of the unloading plate 41. When the unloading plate 41 is opened, it indicates that the barrel 4 is unloading; when the unloading plate 41 is closed, it indicates that the unloading is completed.

[0148] When the second lamp bead lights up, it means that the barrel 4 has been unloaded, and the operator can proceed to the step of replacing the barrel 4. At this time, replacing the new barrel 4 will trigger a status update to ensure that the next work cycle goes smoothly.

[0149] The control module 3 automatically controls the switching of the lamp beads according to the state of the discharge plate 41. When the discharge plate 41 is closed, it means that the material is unloaded, and the system automatically turns off the first lamp bead and turns on the second lamp bead.

[0150] The status of the prompt light 8 is synchronized with the working status of the device in real time, so that the user can quickly intervene or adjust according to the instructions, reducing waiting time and waste of resources.

[0151] In this embodiment, a total of 12 groups of barrels 4 are designed. By configuring the prompt light 8, the barrels 4 after the feeding is completed can be quickly replaced, thereby realizing the configuration input of more groups of materials.
