Description
Technical Field
[0001] The present application relates to the field of plastic production equipment technology, and in particular to a metering device in the production process of nylon materials. Background Art
[0002] Nylon plastic has become an indispensable material in modern society due to its excellent performance and low price. It is widely used in various fields such as machinery manufacturing, daily necessities, medical equipment, aerospace equipment, auto parts, etc. Therefore, companies that produce nylon materials often need to have a larger scale and faster production speed to meet the huge demand for nylon materials.
[0003] Most companies currently use a combination of manual and machine methods to package nylon finished products. The nylon material is placed on a weighing device for weighing by manually opening and closing the valve, and when the packing weight is reached, the valve is manually closed and the nylon material is poured from the weighing device into the bag.
[0004] This method is not only time-consuming and labor-intensive, but also because the staff closes the valve only when the reading on the weighing device reaches the specified value, there will always be a deviation between the final displayed value of the weighing device and the specified value, which will lead to uneven weight of the nylon material in each bag. Utility Model Content
[0005] In order to improve the weighing accuracy of finished nylon material particles when packing and reduce the weight deviation of the nylon material in each bag, the present application provides a metering device in the nylon material production process.
[0006] The present application provides a metering device in the nylon material production process using the following technical solution:
[0007] A metering device in a nylon material production process comprises a silo for containing pellets to be weighed, a feed hopper fixedly mounted on the top of the silo and connected to the inside of the silo, a metering box for weighing the pellets, and a frame, wherein the metering box and the silo are both fixedly mounted on the frame, an opening is provided at the bottom of the silo and a material guide pipe for introducing the pellets into the metering box is provided, a control component is provided on the end of the material guide pipe near the metering box to prevent the pellets from being discharged from the material guide pipe, a slider with a slope on one side is slidably provided in the metering box, a weighing instrument for weighing the pellets is fixedly mounted at the bottom of the metering box, a first cylinder electrically connected to the weighing instrument is fixedly mounted at the bottom of the inner side of the metering box, a telescopic rod of the first cylinder is fixedly connected to the bottom side of the slider, a discharge port is provided on the side of the metering box near the bottom of the slope, and the slider controls the opening and closing of the discharge port by sliding.
[0008] By adopting the above technical solution, after the nylon pellets are put into the feed hopper, the pellets will enter the silo below, and then fall onto the slope at the top of the slider in the metering box through the guide tube. When the weighing instrument shows that the weight of the pellets reaches the specified value, the weighing instrument will send an electrical signal to drive the first cylinder to move the slider downward, so that the pellets are discharged from the discharge port, thereby realizing automatic weighing and unloading of the pellets, thereby avoiding manpower consumption in the weighing process. Moreover, since the pellets entering and exiting the metering box are controlled by electricity, calculation errors in the weighing process can be avoided, thereby improving the accuracy of nylon material weighing.
[0009] Optionally, the control component includes a second cylinder fixedly mounted on the frame and a baffle for preventing material in the material guide tube from entering the metering box, the baffle being fixedly connected to the end of the telescopic rod on the second cylinder, the second cylinder being electrically connected to the weighing instrument, a slide groove being provided along the cross section on the material guide tube at an end position close to the metering box, and the baffle being slidably penetrated into the slide groove.
[0010] By adopting the above technical solution, when the reading of the weighing instrument shows the specified value, the weighing instrument sends an electrical signal to the second cylinder of the control component, and the second cylinder drives the baffle into the slide groove on the material guide tube, thereby immediately blocking the particles from continuing to fall into the metering box below. Moreover, since the cylinder reaction time is faster than that of the workers, it can save manpower and further improve the weighing accuracy of the metering device, thereby avoiding excessive particles in the metering box and causing deviations in the weight of the particles discharged from the metering box.
[0011] Optionally, the bottom size of the slide groove is equal to the outer diameter of the guide tube along the cross section, and the baffle includes an abutment portion and a penetration portion that are integrally connected, and the abutment portion is connected to the second cylinder telescopic rod. When the baffle is located in the slide groove, the abutment portion abuts against one side of the bottom of the slide groove, and the penetration portion abuts against the inner wall of the guide tube, and the penetration portion matches the size of the inner wall of the guide tube.
[0012] By adopting the above technical solution, when the baffle abuts against the slide groove, the abutting part abuts against the bottom of the slide groove, and at the same time, the deep part can completely close the material guide pipe, which can not only ensure the complete blocking of the particles but also protect the inner wall of the material guide pipe, avoiding the baffle from hitting the inner wall of the material guide pipe with a large impact force, thereby improving the safety of the device.
[0013] Optionally, the material guide tube is bent at one end close to the metering box, and the end of the material guide tube is horizontal, and the end of the material guide tube close to the metering box is directly opposite to and close to the top of the slope on the sliding block.
[0014] By adopting the above technical solution, the pellets can have a smaller vertical speed when falling into the metering box, avoiding deviation of the reading of the weighing instrument at the bottom of the metering box due to the impact of the pellets, thereby affecting the weight accuracy of the final nylon material.
[0015] Optionally, the area of the cross section of the bottom of the silo decreases along the central axis direction, and the area of the bottom opening of the silo is the smallest.
[0016] By adopting the above technical solution, the particles inside the silo can flow out from the opening more conveniently, thereby preventing some particles from being deposited at the bottom of the silo and unable to be discharged into the material guide pipe.
[0017] Optionally, a stirring shaft is arranged in the silo along the central axis direction, and a stirring paddle is fixedly sleeved on the stirring shaft, and the stirring paddle is close to the bottom of the silo.
[0018] By adopting the above technical solution, it is possible to prevent excessive particles released from the feed hopper into the silo per unit time from causing blockage at the silo opening. The stirring paddle plays a role in clearing the particles inside the silo, ensuring the stability of the device operation.
[0019] Optionally, an extension plate is installed on the outer wall of the metering box at the discharge port, the extension plate forms an acute angle with the outer wall of the metering box, the extension plate includes a bottom plate and two wing plates arranged at an obtuse angle to the bottom plate, the two wing plates are arranged opposite to each other and connected to both sides of the bottom plate, and the cross-sectional size of the bottom plate decreases in the direction away from the metering box.
[0020] By adopting the above technical solution, when the weighed pellets are discharged from the metering box along the discharge port, the pellets can be collected by extending the material plate to prevent the pellets from flying around, thereby improving the convenience of packing nylon materials and preventing the weight of the nylon materials in the luggage from being reduced due to partial scattering.
[0021] Optionally, when the slider is located at the lowest position in the metering box, the bottom of the slope on the slider and the bottom of the discharge port are on the same horizontal plane.
[0022] By adopting the above technical solution, it can be avoided that when the pellets are discharged from the metering box from the discharge port, a part of the pellets still remain in the metering box, resulting in the weight of the pellets in the bag being less than the weight when weighed in the metering box.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. The present application controls the weight of the pellets in the metering box through electrical connection, thereby avoiding errors caused by manual operation and improving the accuracy of the nylon material metering device when weighing;
[0025] 2. This application can realize the automatic weighing and packing of nylon materials. When used with a conveyor belt, it can avoid manual operation to the greatest extent, reduce material weight deviation and the labor cost of nylon material weighing;
[0026] 3. This application is simple to operate and can realize automatic operation, which improves the efficiency of nylon material measurement and saves the operating steps and time of the measurement process. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is combined with Figure 1-8 This application is described in further detail.
[0037] The embodiment of the present application discloses a metering device in a nylon material production process.
[0038] Reference Figure 1 , a metering device in the production process of nylon materials, including a feed hopper 1 in a cone shape with a bottom opening 21, and a silo 2 placed at the bottom of the feed hopper 1 and used to hold the pellets to be weighed, the interior of the silo 2 is provided with a cavity and is connected to the feed hopper 1. The metering device is provided with a frame 3, and the silo 2 is fixedly installed on the frame 3. An opening 21 is opened at the bottom of the silo 2, and a material guide pipe 4 is fixedly sleeved at the position of the opening 21, and a metering box 5 with an upper opening 21 is placed on the frame 3, and the end of the material guide pipe 4 extends into the inside of the metering box 5. A weighing instrument 6 is installed between the bottom of the metering box 5 and the frame 3 to weigh the nylon pellets in the metering box 5.
[0039] Reference Figure 2 and Figure 3 Specifically, the cross-sectional area of the bottom of the silo 2 in the horizontal direction gradually decreases, and the area at the position of the opening 21 is the smallest, so that the particles inside the silo 2 can be discharged more smoothly. In this embodiment, the bottom of the silo 2 is preferably in a cone shape. A stirring shaft 22 is provided inside the silo 2, and a stirring paddle 23 is fixedly sleeved on the stirring shaft 22. The stirring shaft 22 is driven by a motor fixedly connected thereto, and the motor is not shown in the figure. The stirring paddle 23 is arranged close to the bottom of the silo 2 to facilitate unblocking when the silo 2 is discharged, so as to avoid blockage at the opening 21 of the silo 2.
[0040] Reference Figure 1 and Figure 3 Specifically, the material guide tube 4 is provided with an arc structure, and one end thereof close to the metering box 5 is arranged in the horizontal direction, so as to minimize the vertical speed of the particles released from the material guide tube 4 into the metering box 5, and avoid the particles hitting the inside of the metering box 5 to affect the measurement of the weighing instrument 6, resulting in inaccurate readings.
[0041] Reference Figure 4 , Figure 5 and Figure 6Furthermore, a slider 7 adapted to the size of the inner cross section of the metering box 5 is slidably placed in the metering box 5, and the slider 7 is preferably a trapezoidal block with a sloped top. A first cylinder 52 is fixedly installed at the bottom of the metering box 5, and the end of the telescopic rod of the first cylinder 52 is fixedly connected to the bottom of the slider 7, and the first cylinder 52 is electrically connected and controlled by the weighing instrument 6. The metering box 5 is provided with a discharge port 51 on one side close to the upper bottom surface of the slider 7, which has the same shape and size as the upper bottom surface of the slider 7. When the reading of the weighing instrument 6 does not reach the specified value, the upper bottom surface of the slider 7 blocks the discharge port 51; when the reading of the weighing instrument 6 reaches the specified value, the slider 7 moves downward under the drive of the first cylinder 52, so that the discharge port 51 is opened.
[0042] Reference Figure 5 and Figure 6 In this embodiment, when the slider 7 moves downward, the bottom of its upper slope and the bottom of the discharge port 51 are located on the same horizontal plane to prevent a portion of the particles from being blocked in the groove formed between the slider 7 and the discharge port 51 during the process of the particles being discharged from the metering box 5 from the discharge port 51.
[0043] Reference Figure 1 and Figure 6 Furthermore, the outlet of the guide tube 4 is close to and directly opposite to the top of the slope on the slider 7, so that the particles can have a smaller vertical speed when they are discharged from the guide tube 4 into the metering box 5, so as to avoid the impact of gravity on the metering box 5, which may cause inaccurate readings on the weighing instrument 6.
[0044] Reference Figure 1 and Figure 6 The metering box 5 is fixedly provided with an extension plate 53 at the discharge port 51 to prevent the particles from flying when discharged from the metering box 5. The extension plate 53 forms an acute angle with the side wall of the metering box 5 in the vertical direction, and the angle is preferably between 45 and 90 degrees. The extension plate 53 includes a trapezoidal bottom plate 531 and two wing plates 532 integrally connected to both sides of the bottom plate 531. The two wing plates 532 are arranged opposite to each other and form an obtuse angle with the bottom plate 531 to gather the particles and prevent the particles from sliding down from the side of the bottom plate 531. In addition, a bag 9 for containing the particles that slide down from the extension plate 53 is placed on the frame 3.
[0045] Reference Figure 1 and Figure 7 A control assembly 8 for controlling the in and out of the material guide pipe 4 is provided at a position near the metering box 5 on the material guide pipe 4, including a second cylinder 81 mounted on the frame 3 and a baffle 82 fixedly mounted on the end of the telescopic rod of the second cylinder 81. The second cylinder 81 is electrically connected to the weighing instrument 6 and controlled by the weighing instrument 6. A chute 41 with a semicircular cross section and connected to the inside of the material guide pipe 4 is provided on the material guide pipe 4, and the baffle 82 is slidably arranged inside the chute 41.
[0046] Reference Figure 7 and Figure 8 Furthermore, the baffle 82 includes an abutting portion 821 and a deep portion 822 which are integrally connected. The abutting portion 821 is rectangular in shape, and one end thereof away from the deep portion 822 is fixedly connected to the telescopic rod of the second cylinder 81; the deep portion 822 is semicircular in shape, and its size is equal to the size of the inner wall of the material guide tube 4. When the weighing instrument 6 reaches the specified value, the second cylinder 81 drives the baffle 82 to close the material guide tube 4. At this time, the deep portion 822 on the baffle 82 contacts and completely fits the inner wall of the material guide tube 4, so that the material guide tube 4 is completely closed.
[0047] Furthermore, at this time, the abutting portion 821 abuts against the side wall of the material guiding tube 4 located at the bottom of the slide groove 41 to prevent the blocking piece 82 from hitting too hard and causing the material guiding tube 4 to be damaged.
[0048] The implementation principle of the metering device in the nylon material production process of the present application embodiment is as follows:
[0049] The nylon material pellets flow out of the feed hopper 1 into the silo 2, and then pass through the guide pipe 4 located at the bottom of the silo 2 and connected to the inside of the silo 2, and finally fall onto the slope of the slider 7 in the metering box 5. At this time, the slider 7 is fixed in position under the control of the first cylinder 52, and the pellets are weighed by the weighing instrument 6 located below the metering box 5.
[0050] When the weighing instrument 6 shows that the specified value has been reached, the weighing instrument 6 will send an electrical signal to the first cylinder 52 and the second cylinder 81. At this time, the second cylinder 81 drives the baffle 82 to close the material guide tube 4 to prevent the particles from entering the metering box 5, and at the same time, the first cylinder 52 drives the slider 7 to move downward and open the discharge port 51 on the metering box 5. At this time, the particles on the slope of the slider 7 can smoothly slide onto the extended material plate 53 outside the metering box 5, and then the particles are discharged to complete the weighing of the nylon material.
[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
