Description

Technical Field

[0001] This invention relates to the field of silicone particle processing technology, specifically a silicone processing technology. Background Technology

[0002] The mixing, extrusion, and granulation processes are crucial in silicone masterbatch manufacturing. Granulation, in particular, is performed using a silicone granulator. Silicone of a set diameter is extruded through a die, and then cut off by a cutter. After cooling, the silicone granules are formed. Before producing silicone masterbatch, the cutter needs to be installed on a cutter disc, which is then pressed tightly against the die surface. During cutter installation, because the installation accuracy is ±0.03mm, if a cutter exceeds this tolerance, the pressure on the die will differ from the other cutters during operation. This will cause the cutter's temperature to be higher or lower than the others, and this defect cannot be directly observed. This leads to notches or cracks in the cutter during operation, resulting in substandard masterbatch quality. Often, this problem is only discovered and the machine stopped after a large area of ​​masterbatch quality issues have occurred. The cutter is then removed and inspected, and problems with other components are checked.

[0003] According to a case study in the document "Analysis of the Matching Relationship between Template Cutters in Extrusion Granulator Units" on the Originality Documentation Platform, during a normal start-up of the extrusion granulator at Shenhua Baotou PP plant, it was discovered that the produced masterbatch contained tailings. As production time increased, the tailings also increased, ultimately leading to product defects. The reason was that during the assembly of the cutters by maintenance workers, some cutters deviated significantly, causing one cutter to be either higher or lower than the others. If it was lower, the forward pressure of the cutter during operation would concentrate on that single cutter. During high-speed rotation, this caused the cutter to break or chip under the excessive load. At this point, the loss had already occurred, and the cutter needed to be replaced, resulting in economic losses, wasted time, and reduced production efficiency.

[0004] To address this, a silicone processing technology is proposed. This technology detects the frictional heat generated when the cutter contacts the die head to indicate the installation accuracy of the cutter. The color of the light also indicates the operator's status of the cutter, helping the operator to quickly determine whether a fault occurs at the cutter and reduce economic losses.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a silicone processing technology that detects the frictional heat generated when the cutter contacts the mold head to reflect the installation accuracy of the cutter, and uses light color to indicate the operator's working status of the cutter, helping the operator to more quickly determine whether a fault occurs at the cutter, reducing economic losses, and thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A silicone processing technology, comprising:

[0009] S1: Mix the silicone and additives in a mixer. During the silicone mixing process, first check the installation accuracy of the cutter. Install the cutter on the cutter disc, move the cutter disc to fit tightly against the die head on the granulator, apply a predetermined pressure to the cutter disc through a press, and start the motor to drive the cutter disc to rotate on the surface of the die head. During this period, the detection device judges the installation accuracy of the cutter by detecting the temperature of the cutter. When the installation accuracy of the cutter is greater than the tolerance value, the detection device alarms the operator.

[0010] S2: After ensuring the accuracy of the cutter installation, the mixed silicone is transported into the feeder by the elevator;

[0011] S3: The feeder introduces silicone into the granulator through the screw. The silicone is further mixed under the pressure of the granulator and extruded from the die at the output of the granulator. The cutter cuts the extruded silicone into granules, which are then formed in the cooling chamber.

[0012] S4: The formed silicone granules are sorted into bags by a vibrating screen;

[0013] The granulator includes a die head, a cutter, a motor, a cooling chamber, a moving platform, a press, and a cutter disc. The extrusion end of the granulator is fixedly equipped with a cooling chamber. The die head is fixedly installed on the granulator and located in the cooling chamber. A moving platform is fixedly installed on one side of the die head. A motor is movably installed on the moving platform. A cutter disc is fixedly installed at the output end of the motor. A cutter is fixedly installed on the cutter disc. A press is fixedly installed on the moving platform. The press applies pressure to the cutter disc, causing the cutter to make close contact with the die head.

[0014] After being mixed in a mixer, the silicone is introduced into a granulator. The pressure applied to the silicone by the granulator makes the silicone fully mixed and extruded into the die. The die has multiple forming holes, and the silicone is extruded from the forming holes. The cutter is driven by a motor and rotates close to the surface of the die. The extruded silicone is cut by the cutter and cooled through a cooling chamber. The finished silicone masterbatch is obtained.

[0015] To avoid the formation of backing material, pressure is usually applied to the cutter, causing it to rotate tightly against the die head. This generates a significant amount of internal energy. Therefore, the cooling chamber not only cools the silicone but also prevents the cutter from overheating, thus extending its lifespan. However, if the installation precision between the cutter and the die head is insufficient, some cutters may experience temperatures higher or lower than others. This defect is not directly observable and often only occurs after widespread masterbatch quality issues arise, requiring the machine to be stopped, the cutters removed and sent for inspection, and other components checked. By this time, economic losses have already been incurred, and the disassembly and assembly of the cutters require high precision. If the problem is not with the cutter's installation, reassembly will consume a considerable amount of time.

[0016] Preferably, the detection device includes a detection cylinder fixedly mounted on the cutter. A guide rod is slidably mounted inside the detection cylinder, and a power supply is fixedly mounted on the guide rod. Multiple interfaces cooperating with the power supply are fixedly mounted on the inner wall of the detection cylinder. The interface located on the upper side of the detection cylinder is used to detect the temperature of the cutter when it is higher than the normal operating temperature, and the interface located on the lower side of the detection cylinder is used to detect the temperature of the cutter when it is lower than the normal operating temperature. A magnetic object is fixedly mounted on one end of the guide rod, and a magnet for attracting the magnetic object is fixedly mounted on the end of the detection cylinder. The magnet is located at the end of the detection cylinder near the cutter head. A lamp holder electrically connected to the interface is fixedly mounted on the side wall of the detection cylinder, and a pull rope is fixedly mounted on the magnetic object. One end of the pull rope is fixed to the inner wall of the detection cylinder.

[0017] Furthermore, ball bearings are rotatably mounted at the ends of the magnetic material and the guide rod.

[0018] The lamp holder is electrically connected to the interface. The magnet attracts the magnetic material. When the production of silicone masterbatch stops, the magnet attracts the magnetic material to its surface. At this time, the power supply and the interface remain in contact. The inspection cylinder is fixedly installed on the cutter. When the cutter rotates, the friction between the cutter and the die head gradually increases the temperature, which in turn increases the temperature of the magnet, causing the magnetism of the magnet to decrease. The magnetic material is detached from the magnet under the action of centrifugal force. As the magnetism of the magnet decreases, the pull rope is stretched by the magnetic material. The resultant force of the attraction between the magnet and the magnetic material and the elastic force of the pull rope gradually equals the centrifugal force, causing the power supply and the magnetic material to suspend in the middle of the inspection cylinder.

[0019] If the cutting edge of the cutter is positioned ahead of the other cutters, the wear on the cutter gradually increases as it rotates close to the die head. This increases the contact pressure between the cutter and the die head, raising the temperature of the cutter and consequently the temperature of the magnet. The magnetism of the magnet further decreases, at which point the attraction of the magnet to the magnetic object is less than the centrifugal force. The guide rod and the magnetic object move upwards, allowing the power supply to engage with the interface, illuminating the indicator light. This alerts the operator that there is an abnormality in the fit between the cutter and the die head, enabling the cutter to be replaced promptly and avoiding excessive economic losses. Furthermore, if the equipment malfunctions but the indicator light does not illuminate, the flatness of the cutter and die head can be ruled out, avoiding frequent disassembly and reassembly of the cutter and allowing for a faster solution.

[0020] On the other hand, temperature changes in the cutter can also reflect the surface roughness and perpendicularity of the die head. Since the cutters are assembled on the cutter head, it's rare for each cutter to be incorrectly installed. Therefore, if the detection cylinders on every cutter are triggered during operation, the problem is more likely with the die head. Inspection should focus on checking the surface roughness or perpendicularity of the die head. Similarly, it can also indicate whether the pressure applied to the cutter head is excessive.

[0021] If the cutting edge of the cutter is located behind the other cutters, the contact between the cutter and the die head is less than that of the other cutters. The temperature of the cutter during the production process is lower than that of the other cutters. The direction of movement of the guide rod and the magnetic object is opposite to that when the assembly height of the cutter is lower than that of the other cutters. The light head will also light up to remind the operator. This will not be explained in detail here.

[0022] It should be understood that while the method of using a lit indicator light to alert the operator is described here, this is not the only method. Alternatively, an interface can be used to connect wirelessly to an external control panel, allowing the test results to be displayed on the control screen quickly and easily without needing to approach the granulator.

[0023] By incorporating ball bearings at the ends of the guide rod and the magnetic material, rolling friction replaces the original sliding friction, reducing the interference of friction on the guide rod and the magnetic material caused by the inner wall of the inspection cylinder. When the fit between the cutter and the die head is insufficient, the power supply and interface can fit together more quickly, improving the detection accuracy.

[0024] Preferably, a rubber pad is fixedly installed on the side wall of the interface.

[0025] When the balance between the attractive force of the magnet and the centrifugal force of the cutter is broken, the attractive force decreases with distance from the magnet, while the centrifugal force increases. The forces of the two drive guide rods and the magnetic material cannot reach a new balance, causing the power supply to continuously move in one direction. This prevents the power supply and interface from maintaining a proper fit for extended periods. Furthermore, the operator cannot constantly monitor the cutter's operation. To prevent undetected abnormalities in the cutter's installation accuracy, a rubber pad is fixed to the side wall of the interface. When the power supply mates with the interface, the pad increases friction, causing the power supply to remain at the interface after mating, allowing the operator to easily detect the issue and increasing the fault tolerance of the detection device.

[0026] Preferably, a conical groove is formed in the side wall of the detection cylinder, a slider is slidably installed in the conical groove, the interface is fixedly connected to the slider, and two spring plates are fixedly installed on the slider, with steel balls fixedly installed on both spring plates.

[0027] Furthermore, the slider has multiple arc-shaped grooves that cooperate with the steel ball, and the multiple arc-shaped grooves are connected to the conical grooves.

[0028] Furthermore, the interfaces are staggered on both sides of the inner wall of the detection cylinder.

[0029] Furthermore, two interfaces are provided on the inner wall of the detection cylinder.

[0030] The frictional heat between the cutter and the die head is proportional to the product of the cutter contact pressure and the cutter rotation speed. Under normal circumstances, the contact pressure between the cutter and the die head is constant. However, as the rotation speed increases, the temperature of the cutter rises, causing the magnetic force of the magnet to decrease while the centrifugal force increases. Therefore, the attraction of the magnet to the magnetic material and the centrifugal force cannot reach a new balance. Thus, when producing silicone masterbatches with different ratios, the cutter rotation speed needs to be adjusted. In this case, if the detection cylinder is not replaced, even if the cutter installation accuracy is correct, the power supply inside the detection cylinder will still misinterpret the interface at high rotation speeds.

[0031] By measuring the distance between the magnet and the magnetic object when the rotation speed remains constant, a pull rope is placed between the two objects. This rope is not stretched when the magnet is suspended. However, when the cutter's rotation speed changes, the tension in the rope on the magnetic object balances the centrifugal force, magnetic force, and tension, restoring the magnetic object to a state of equilibrium. Therefore, by simply adjusting the interface to match the cutter's rotation speed, the required accuracy of the cutter installation can be tested at various rotation speeds.

[0032] By sliding the interface within a conical groove on the inner wall of the detection cylinder, and utilizing the shape of the groove, the steel balls continuously compress the spring sheet during the slider's movement. This increases the friction between the steel balls and the conical groove, limiting the slider's movement distance and ensuring that the interface and guide rod move at roughly the same distance. This eliminates concerns about misjudgments caused by the power supply prematurely aligning with the interface due to changes in the cutter's rotation speed. The detection cylinder can then be mounted on the cutter for extended periods until the cutter wears out beyond its service life, avoiding the need to replace internal components to adjust for different cutter speeds and improving the cylinder's practicality.

[0033] It is worth noting that, since the interfaces are staggered on both sides of the inner wall of the detection cylinder, after the conical groove is opened, when the power supply and the interface are engaged, the balls on the side wall of the magnetic material or the guide rod will be in the conical groove. However, when the balls of the magnetic material enter the conical groove, the balls on the guide rod are in complete contact with the inner wall of the detection cylinder. This ensures that the guide rod does not deviate during movement.

[0034] Because it is difficult to control the displacement of the slider at different speeds, in order to accurately control the movement distance of the slider under changes in the cutting speed and keep the movement distance of the slider and the power supply consistent, an arc groove is set in the slider. When the ball enters the arc groove, it can remain stationary within a certain rotation range. It can be understood that no stop is set for the slider at different speeds. The interval of the arc groove is equal to the elongation of the pull rope after a large change in speed, so that the slider and the guide rod move synchronously.

[0035] The two notches control the two colors of the lamp head, and the color of the lamp head can be used to visually indicate the degree of blade offset.

[0036] Preferably, the detection cylinder is fixedly mounted on the back of the cutter.

[0037] For air-cooled granulators, silicone is cooled and shaped in the cooling chamber by air or a water ring on the die. When the cutter cuts the silicone from the die, the silicone is thrown off the cutter surface, causing the silicone masterbatch to bounce irregularly within the cooling chamber. If the detection cylinder is placed on the front or top wall of the cutter, the bounced silicone masterbatch can easily interfere with the detection cylinder, leading to misjudgments. Therefore, the detection cylinder is placed on the back of the cutter, reducing the impact of the bounced silicone masterbatch. Furthermore, the detection cylinder is located on the leeward side of the cutter, where the temperature change is smaller during cutter rotation, allowing the magnet to synchronize with the cutter temperature more quickly and accurately.

[0038] For underwater granulators, since the cutter itself has no inclined or curved surface, the water resistance on the cutter surface is small. If the detection cylinder is placed on the front or top wall of the cutter, it will be constantly eroded by the water flow during the cutter's rotation, which is not conducive to fixation. Furthermore, the eroding water flow frequently exchanges heat with the detection cylinder, significantly reducing the synchronization speed between the magnet temperature and the cutter temperature, and slowing down the feedback of detection results. Therefore, placing the detection cylinder on the back of the cutter reduces the erosion of the detection cylinder by the water flow, ensures the stability of the detection cylinder, improves its service life, and reduces the frequency of heat exchange between the water flow and the detection cylinder, thus speeding up the detection time.

[0039] Preferably, a heat-conducting sheet is fixedly installed on the mounting surface of the detection cylinder and the cutter.

[0040] Because the cutter is made of Cr12MoV, which has a low thermal conductivity, the magnetic object only gradually comes to a suspended state after the cutter and die head rub against each other for a period of time. During this period, the magnet heats up slowly, resulting in a longer feedback time from the detection cylinder. By placing a heat-conducting plate between the cutter and the magnet, the magnet's temperature can be synchronized with the cutter more quickly, thus accelerating the detection speed. This allows operators to quickly understand the cutter's operating status, make timely corrections, and reduce economic losses.

[0041] Preferably, the interface includes a fixing part and a connecting part, the fixing part is fixedly connected to the slider, and the connecting part is connected to the fixing part by a spring.

[0042] A magnet is installed on the connecting part. The magnet can attract the power source. The magnet's magnetism is very weak, and it can stretch the spring by a maximum of 0.3mm. The horizontal distance between the power source and the interface is set to 0.1mm. When the power source is close to the interface, the interface engages with the power source through the magnet, increasing the engagement margin and preventing the interface or power source from shifting position and failing to engage when rotating at high speed on the cutter.

[0043] Preferably, the bottom wall of the detection cylinder is tangent to the side wall of the cutter disc.

[0044] When the bottom wall of the detection cylinder is tangent to the cutter head, the axis of the guide rod and the centrifugal force are aligned, reducing the conditions required for calculating the equality of the magnetic force and centrifugal force of the magnetic material. Furthermore, it ensures that the guide rod is subjected to force in only one direction during movement, thus guaranteeing the measurement accuracy of the detection cylinder.

[0045] Preferably, the detection cylinder is fixedly installed with an inclined block for smoothly detaching the magnetic object from the magnet, and the inclined block is made of a soft material.

[0046] When a magnetic object detaches from a magnet, the centrifugal force it experiences gradually increases. When the distance the magnetic object moves exceeds the length of the pull rope, the pull rope is suddenly stretched, which can easily cause the power supply and interface to accidentally touch.

[0047] To address this, an inclined block is installed on the inner wall of the detection cylinder near the magnet. As the magnetic object moves upward along the inclined block, the ball is gradually pressed into the inclined block, and the resistance experienced by the magnetic object gradually increases to counteract the gradually increasing centrifugal force, ensuring that the magnetic object does not stretch the pull rope excessively at once and avoiding detection errors.

[0048] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0049] 1. A detection device is installed on the cutter. The frictional heat generated between the cutter and the die head during operation reflects the installation status of the cutter. When the installation accuracy of the cutter is greater than the positive tolerance, its working temperature is higher than that of other cutters, the magnetic force of the magnet decreases, the power supply and interface maintain continuous coordination, and the light head illuminates to indicate the operator's working status of the cutter. This helps the operator to quickly determine whether the fault occurs at the cutter and reduce economic losses.

[0050] 2. A conical groove is formed on the inner wall of the detection cylinder. The interface is slidably placed within the conical groove in the inner wall of the detection cylinder. Utilizing the shape characteristics of the conical groove, the ball bearings continuously squeeze the spring during the movement of the slider, increasing the friction between the ball bearings and the conical groove. This limits the movement distance of the slider, ensuring that the movement distance of the interface and the guide rod are equal. This avoids misjudgments caused by the power supply prematurely aligning with the interface due to changes in the cutter's rotational speed. Thus, even after the rotational speed is adjusted, the detection cylinder can still perform detection work on the cutter, ensuring that the detection cylinder can be mounted on the cutter at various rotational speeds until the cutter wears beyond its service life. This avoids the need to replace components within the detection cylinder to match the cutter's rotational speed, improving the practicality of the detection cylinder.

[0051] 3. A rubber pad is fixedly installed on the side wall of the interface. When the power supply is mated with the interface, the rubber pad increases the friction between the power supply and the interface, so that the power supply stays at the interface after mating, so that the operator can detect it at any time and increase the fault tolerance of the detection device.

Detailed Implementation

[0059] The aspects and features of this disclosure, as well as the methods for implementing these aspects and features, will be apparent; however, this disclosure is not limited to the embodiments disclosed below and can be implemented in various forms. These embodiments are provided to assist those skilled in the art in fully understanding this disclosure, and this disclosure is limited only to the scope of the appended claims.

[0060] Example 1: When producing silicone masterbatch with a length of 1cm, please refer to... Figures 1 to 6 This invention provides a silicone processing technology, the technical solution of which is as follows:

[0061] Start the internal mixer and put the silicone and additives into the mixer to mix. During the silicone mixing process, first check the installation accuracy of the cutter 2.

[0062] An additional die head 1 is prepared to test the installation accuracy of the cutter 2 during operation. This die head 1 is fixed to the bracket, and 90°C hot water is introduced into it to replace the silicone. Since the silicone cools instantly in the cooling chamber 6 when extruded from the die head 1, the extruded material from the die head 1 has very little impact on the cutter 2, allowing hot water to be used instead and saving costs. The die head 1 is then heated to the temperature used in actual silicone masterbatch production. This completes the simulation of the operating conditions for the cutter 2 during production.

[0063] Before the cutter 2 is inspected, the inspection cylinder 5 is fixed to the back of the cutter 2 by welding or gluing. The cutter 2 is then assembled into the cutter disc 3, and the cutter disc 3 is fixedly mounted on the output shaft of the motor 4. The motor 4 is fixedly mounted on the guide rail. The motor 4 is moved so that the cutter disc 3 is in close contact with the surface of the die head 1. Pressure is applied to the cutter disc 3 by a press, and the applied pressure is 6MPa to ensure that the cutter 2 and the die head 1 remain in contact.

[0064] Set the speed of motor 4 to 1000 N / min (this speed should be the most commonly used speed in actual production; this is just an example and should be based on the actual situation). Measure the lowest temperature of the cutter 2 after working for 1 minute when the installation accuracy is -0.03 mm, -0.02 mm, and -0.01 mm, and set this temperature as Y.

[0065] When motor 4 is started, the cutter 2 rotates tightly against the die head 1. Since the magnetic object 507 is initially positioned on the magnet 506, the power supply 503 and interface 508 remain in contact, and the lamp head 512 emits red light. Under normal installation accuracy, after 1 minute of rotation, the magnetic object 507 detaches from the magnet 506, and the lamp head 512 goes out. If the lamp head 512 on the detection cylinder 5 still emits red light after 1 minute of rotation, it indicates that the installation accuracy of the cutter 2 installed on the detection cylinder 5 has an error, and it is less than -0.03mm.

[0066] Specifically, when the installation accuracy of a certain cutting blade 2 is less than -0.03mm, causing the cutter disc 3 to be tightly pressed against the die head 1, the cutting blade 2 is not in complete contact with the die head 1, and the contact pressure is less than that of the other cutting blades 2. The frictional heat generated between the cutting blade 2 and the die head 1 reduces the magnetic force of the magnet 506. At this time, the resultant force of the centrifugal force on the cutting blade 2, the attraction force of the magnet 506 on the magnetic object 507, and the elastic force of the pull rope 502 gradually equalizes with the centrifugal force, and the magnetic object 507 is suspended inside the detection cylinder 5. However, for the cutter 2 that is not in complete contact with the die head 1, the temperature of its blade is lower than that of the other cutters 2, and the temperature of the blade of the cutter 2 is less than Y. The attraction of the magnet 506 installed on the cutter 2 to the magnetic object 507 is greater than the centrifugal force on the cutter 2, and the magnetic object 507 cannot move. The power supply 503 and the interface 508 are always in a working state, and the lamp head 512 continuously emits red light. If the duration of the red light is greater than 1 minute, the machine should be stopped immediately, the installation accuracy of the cutter 2 should be adjusted, and the installation accuracy with the die head 1 should be retested.

[0067] When producing silicone masterbatch with a length of 0.5cm, maintain the original silicone extrusion speed and adjust the rotation speed of the cutter head 3 to 2000 N / min. When the cutter head 3 is at 1000 N / min, the distance between the magnetic object 507 and the magnet 506 is measured to be 5mm; therefore, the length of the pull rope 502 is 5mm.

[0068] After the cutter head 3 starts to rotate, the pull rope 502 is stretched by 1mm. At this time, the magnet 506 and the interface 508 also move upward by 1mm, so that the power supply 503 and the interface 508 always maintain contact in the initial stage. When the cutter 2 is fully heated, the internal changes of the detection cylinder 5 of the cutter 2 with an installation accuracy exceeding 0.03 can be the same as described above. In this way, even after the speed is adjusted, the detection cylinder 5 can still perform detection work on the cutter 2, ensuring that the detection cylinder 5 can be mounted on the cutter 2 at various speeds until the wear of the cutter 2 exceeds the service range. This avoids the need to replace the components inside the detection cylinder 5 to match the speed of the cutter 2, thus improving the practicality of the detection cylinder 5.

[0069] If no indicator light 512 illuminates after the cutter 2 rotates on the die head 1 for more than 1 minute, the mixed silicone can be fed into the feeder via the elevator. The screw then guides the silicone into the granulator, where it is further mixed under pressure and extruded from the die head 1. The cutter 2 cuts the extruded silicone into granules, which are then shaped in the cooling chamber 6. Finally, the shaped silicone granules are screened by a vibrating sieve and placed into bags.

[0070] A rubber pad 509 is fixedly installed on the side wall of the interface 508. When the interface 508 comes into contact with the power supply 503, the rubber pad 509 increases the friction between the interface 508 and the power supply 503, causing the power supply 503 to stay at the interface 508. This allows the operator to detect the problem at any time and increases the fault tolerance of the detection device.

[0071] Two interfaces 508 are provided on the inner wall of the detection cylinder 5. When the installation accuracy deviation of the cutter 2 is too large, the power supply 503 will break free from the restraint of the rubber pad 509 and move to the second interface 508. The two interfaces 508 control the two colors of the lamp head 512 respectively. The degree of offset of the cutter 2 can be intuitively reflected by the color of the lamp head 512, allowing the operator to sort out the solution more quickly.

[0072] Interface 508 connects to an external control panel via wireless signal, displaying the test results directly on the control panel. The test results can be observed quickly without having to approach the granulator.

[0073] The circuit that electrically connects interface 508 and lamp holder 512 is equipped with an energy storage component, such as a capacitor. After the cutter head 3 stops rotating, the lamp holder 512 continues to light up, visually displaying the installation status of each cutter 2 on the cutter head 3.

[0074] The detection cylinder 5 is fixedly installed on the back of the cutter 2. In this way, whether the granulator is air-cooled or water-cooled, the resistance of the detection cylinder 5 to the cutter 2 can be reduced, so that the cutter 2 is subjected to uniform force during rotation. In addition, the heat exchange frequency between the detection cylinder 5 and the medium in the cooling chamber 6 is reduced, and the detection time of the detection cylinder 5 is accelerated.

[0075] A heat-conducting plate 505 is fixedly installed on the mounting surfaces of the detection cylinder 5 and the cutter 2 to accelerate the temperature synchronization between the magnet 506 and the cutter 2, thereby speeding up the detection process. This allows the operator to quickly understand the usage status of the cutter 2, take timely remedial action, and reduce economic losses.

[0076] The detection cylinder 5 is installed on the lower back of the cutter 2. The vertical height of the cutter 2 is 5cm, and the length of the masterbatch is 1cm. The detection cylinder 5 is placed on the cutter 2 at a distance of 1cm from the surface of the die head 1. This not only affects the extrusion of silicone, but also further accelerates the temperature synchronization between the magnet 506 and the cutter 2.

[0077] Example 2

[0078] While maintaining the testing conditions in Example 1, the highest temperature of the cutter 2 was tested for 1 minute at installation accuracies of +0.03mm, +0.02mm, and +0.01mm, and this temperature was set as X.

[0079] When the installation accuracy of a certain cutter 2 on the cutter head 3 is greater than +0.03mm, the contact pressure between this cutter 2 and the die head 1 is greater than that of the other cutters 2. After the cutter 2 has been fully heated for 1 minute, the resultant force of the centrifugal force on the cutter 2, the attraction force of the magnet 506 to the magnetic object 507, and the elastic force of the pull rope 502 is equal to the centrifugal force. The magnetic object 507 is suspended inside the detection cylinder 5. For the cutter 2 with an installation accuracy greater than +0.03mm, the working temperature of this cutter 2 is greater than X, which causes the magnetic force of the magnet 506 on this cutter 2 to be less than that of the magnet 506 on the other cutters 2. This causes the magnetic object 507 to move upwards in the detection cylinder 5, and the pull rope 502 is stretched until the resultant force of the centrifugal force on the cutter 2, the magnetic force of the magnet 506, and the elastic force of the pull rope 502 reaches a new equilibrium. At this time, the power supply 503 engages with the interface 508 at the top of the detection cylinder 5, and the lamp head 512 emits an orange light. This informs the staff of the installation status of the cutter 2.
