AI Technical Summary
[0014] 1. This utility model uses a calibration control mechanism, an electronic scale module, a solenoid valve module, and a spring to work together. When the target weight of color masterbatch is injected into the packaging bag, the insert rotates, and the spring is pressed down the same distance each time. The same deformation distance of the spring each time means that the weight is the same. At the same time, the sensor on the electronic scale module is also detecting the weight data of the color masterbatch in real time. By weighing and packaging through these two mutual calibration methods, even if the electronic scale module or the solenoid valve module malfunctions or the parameter setting is incorrect, color masterbatch cannot be added into the bag, thereby achieving the effect of making the weight of color masterbatch relatively uniform in each bag after packaging.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of automatic bagging machine for color masterbatch packaging, and in particular to a weighing and packaging equipment for color masterbatch processing. Background Technology
[0002] Color masterbatch is a new type of special colorant for polymer materials. It is composed of three basic elements: pigment or dye, carrier and additives. It is usually in granular form and is chemically stable at room temperature. In practice, automatic bagging machines or fully automatic quantitative packaging scales are often used to package color masterbatch in waterproof and sealed bags about 50 cm long and 70 cm wide for logistics transportation and storage. However, in actual scenarios, we have found that the bagged color masterbatch after being packaged in batches by automatic bagging machines often has inconsistent weights and inaccurate measurement, which leads to many after-sales disputes.
[0003] For example, Chinese utility model patent CN215753106U discloses a packaging device for a color masterbatch granulation system, belonging to the field of color masterbatch processing equipment. The spiral feeding device includes a feeding barrel, a screw installed in the feeding barrel, and a motor that drives the screw to rotate. Although this solution uses an electronic scale installed on a bracket and controls the weight of the packaged color masterbatch through an operation panel, in practice, sensor failures, blockages or damage to the feeding mechanism, and incorrect program parameter settings often lead to inconsistent weights of the packaged color masterbatch. Based on this, a weighing and packaging device for color masterbatch processing is proposed. Utility Model Content
[0004] To address the technical problem of inconsistent packaging weights in automatic masterbatch bagging machines, this utility model provides a weighing and packaging device for masterbatch processing.
[0005] This utility model is achieved using the following technical solution: a weighing and packaging device for color masterbatch processing, comprising an automatic bag-feeding machine base module, wherein multiple sliding rods are slidably connected to the automatic bag-feeding machine base module, and a placement plate is fixedly connected to the upper end of the multiple sliding rods. A spring is sleeved on the outer side of each sliding rod, the upper end of each spring is connected to the lower side of the placement plate, and the lower end of each spring is connected to the upper side of the automatic bag-feeding machine base module. An electronic scale module is installed on the lower side of the placement plate. A lifting rod is fixedly connected to one side of the placement plate, and a limiting cylinder is fixedly connected to the upper end of the lifting rod. A calibration control mechanism is provided inside the limiting cylinder. A color masterbatch feeding mechanism is provided on one side of the automatic bag-feeding machine base module, and a bag unloading mechanism is provided on the other side of the automatic bag-feeding machine base module. A bag-supporting adapter mechanism that mates with the bag opening is provided on the lower side of the limiting cylinder.
[0006] As a further improvement to the above solution, the calibration control mechanism includes a sleeve rotatably connected to the inner side of the limiting cylinder. An upper base plate is fixedly connected to the lower side of the sleeve, and an upper slot is formed through the upper base plate. A lower base plate is fixedly connected to the lower side of the limiting cylinder, and a lower slot is formed through the lower base plate. The upper slot and the lower slot are paired. A sleeve rotation mechanism is provided on the inner side of the sleeve to align or offset the upper slot and the lower slot.
[0007] As a further improvement to the above solution, the sleeve rotation mechanism includes multiple curved sliding groove mechanisms respectively opened on the inner side of the sleeve;
[0008] The curved groove includes a spiral groove and multiple straight grooves. The spiral grooves and straight grooves are arranged in a circumferential array, and the lower end of each spiral groove is connected to the upper end of each straight groove.
[0009] A plug tube is inserted into the inner side of the sleeve, and a solenoid valve module is installed on one side of the upper end of the plug tube. Multiple pointer pins are fixedly connected to the outer side of the plug tube. The multiple pointer pins are distributed in a circumferential array, and one end of each pointer pin slides inside each curved slide mechanism.
[0010] As a further improvement to the above solution, the color masterbatch feeding mechanism includes a weighing beam fixedly connected to one side of the automatic bagging machine base module, a hopper fixedly connected to the upper end of the weighing beam, and the lower side of the hopper communicating with the upper end of the insert cylinder.
[0011] As a further improvement to the above solution, the bag feeding mechanism includes a conveyor belt module installed on the side of the automatic bag feeding machine base module away from the weighing beam.
[0012] As a further improvement to the above solution, the sleeve rotation mechanism includes a bag opening sleeve that communicates with the lower side of the limiting cylinder.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model uses a calibration control mechanism, an electronic scale module, a solenoid valve module, and a spring to work together. When the target weight of color masterbatch is injected into the packaging bag, the insert rotates, and the spring is pressed down the same distance each time. The same deformation distance of the spring each time means that the weight is the same. At the same time, the sensor on the electronic scale module is also detecting the weight data of the color masterbatch in real time. By weighing and packaging through these two mutual calibration methods, even if the electronic scale module or the solenoid valve module malfunctions or the parameter setting is incorrect, color masterbatch cannot be added into the bag, thereby achieving the effect of making the weight of color masterbatch relatively uniform in each bag after packaging.
[0015] 2. This utility model utilizes a rotating connection between a limiting cylinder and a sleeve to achieve mutual cooperation. Lower and upper slots are respectively opened on the lower and upper base plates. As the weight of the masterbatch on the placement plate gradually increases, the spring is compressed and deformed, the sleeve rotates, and the lower and upper slots are staggered. At this time, the masterbatch particles stop flowing down. This purely mechanical method of measuring the weight of the masterbatch is not easily affected by unpredictable external factors, making packaging and weighing more reliable. In addition, it also has the advantages of high wear resistance and long service life. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0025] Example:
[0026] Please combine Figure 1 - Figure 6This embodiment of a weighing and packaging device for color masterbatch processing includes an automatic bag-loading machine base module 1. Four sliding rods 3 are slidably connected to the automatic bag-loading machine base module 1. The upper ends of the four sliding rods 3 are all fixedly connected to a placement plate 10. A spring 4 is sleeved on the outer side of each sliding rod 3. An adjusting bolt is provided at the lower end of each sliding rod 3. The tension of the spring 4 is controlled by the adjusting bolt. According to Hooke's Law, when loading and packaging color masterbatch of different weights, they can be adapted to each other. The upper end of each spring 4 is connected to the lower side of the placement plate 10, and the lower end of each spring 4 is connected to the... The automatic bag-loading machine base module 1 is connected to the upper side, and the electronic scale module 2 is installed on the lower side of the placement plate 10. The electronic scale module 2 is used to display the weight of the color masterbatch loaded in the current packaging bag. A lifting rod 5 is fixedly connected to one side of the placement plate 10. A limiting cylinder 13 is fixedly connected to the upper end of the lifting rod 5. A calibration control mechanism is set inside the limiting cylinder 13. A color masterbatch feeding mechanism is set on one side of the automatic bag-loading machine base module 1. A bag unloading mechanism is set on the other side of the automatic bag-loading machine base module 1. A bag-supporting adapter mechanism that connects with the bag opening is set on the lower side of the limiting cylinder 13.
[0027] It should be noted that the automatic bagging machine base module 1 located on both sides of the placement plate 10 is equipped with a conveying component to transport the packaged masterbatch from the placement plate 10 to the conveyor belt module 11 to complete the unloading. This process is currently quite mature and is not within the scope of protection of this patent.
[0028] The above scheme can create two ways to measure color masterbatch in packaging bags. One is the direct weighing mode of electronic scale module 2. However, this mode is easily affected by factors such as sensors and circuits, but it has the advantages of fast response speed, intuitive data display and industrial communication control. The other is the weight measurement method represented by multiple springs 4. By calibrating the two methods with each other, the weight of color masterbatch in each bag can be guaranteed to be uniform.
[0029] Please screenshot Figure 5 As shown, the calibration control mechanism includes a sleeve 14 rotatably connected to the inner side of the limiting cylinder 13. An upper base plate 19 is fixedly connected to the lower side of the sleeve 14, and an upper slot 17 is formed through the upper base plate 19. A lower base plate 18 is fixedly connected to the lower side of the limiting cylinder 13, and a lower slot 16 is formed through the lower base plate 18. Figure 5 As shown, the upper slot 17 and the lower slot 16 are fan-shaped structures with a certain curvature. With this technical solution, when the sleeve 14 rotates, the upper slot 17 and the lower slot 16 will intersect or stagger each other, creating a window period, so that the flow rate of the masterbatch gradually decreases. The upper slot 17 and the lower slot 16 are paired and set. The inner side of the sleeve 14 is provided with a sleeve rotation mechanism that aligns or staggers the upper slot 17 and the lower slot 16.
[0030] Please combine Figure 6As shown, the sleeve rotation mechanism includes two curved sliding groove mechanisms respectively opened on the inner side of the sleeve 14;
[0031] The curved groove includes a spiral groove 21 and two straight grooves 20. The two spiral grooves 21 and the straight grooves 20 are arranged in a circular array, and the lower end of each spiral groove 21 is connected to the upper end of each straight groove 20.
[0032] A sleeve 8 is inserted into the inner side of the sleeve 14. A solenoid valve module 12 is installed on one side of the upper end of the sleeve 8. Two pointer pins 15 are fixedly connected to the outer side of the sleeve 8. The two pointer pins 15 are arranged in a circumferential array. One end of each pointer pin 15 slides inside each curved slide mechanism.
[0033] Using the above technical solution, taking this embodiment as an example, please refer to... Figure 4 As shown, when the weight of the masterbatch in the packaging bag gradually increases, the pointer pin 15 pushes the sleeve 14 to rotate clockwise, and the upper groove 17 rotates to one side. The upper groove 17 and the lower groove 16 are offset from each other, and the flow port gradually becomes smaller. At this time, the solenoid valve module 12 has been closed. The masterbatch remaining in the sleeve 14 can still flow downward into the masterbatch packaging bag through the space channel formed by the gradually smaller upper groove 17 and the lower groove 16.
[0034] Please combine Figure 4 As shown, the color masterbatch feeding mechanism includes a weighing beam 6 fixedly connected to one side of the automatic bagging machine base module 1. A hopper 7 is fixedly connected to the upper end of the weighing beam 6. The lower side of the hopper 7 is connected to the upper end of the insert cylinder 8. The hopper 7 is used to load color masterbatch for packaging and weighing.
[0035] Please combine Figure 1 As shown, the bag feeding mechanism includes a conveyor belt module 11 installed on the side of the automatic bag feeding machine base module 1 away from the weighing beam 6. The conveyor belt module 11 can transport out the packaged and weighed masterbatch bags one by one.
[0036] Please combine Figure 2 As shown, the sleeve rotation mechanism includes a bag opening sleeve 9 that is connected to the lower side of the limiting cylinder 13. The bag loading module in the automatic bag loading machine can fit the bag opening of the packaging bag onto the outer edge below the bag opening sleeve 9. In addition, the automatic bag loading machine on the market is a very mature technology.
[0037] The implementation principle of a weighing and packaging device for color masterbatch processing in this embodiment is as follows: Before packaging and weighing, the bag loading module of the automatic bag loading machine has already placed the bag opening on the outside of the bag opening hopper 9. The PLC controls the solenoid valve module 12 on the outside of the insert cylinder 8 to open. Then, the color masterbatch in the hopper 7, under its own gravity, first passes through the upper slot 17 and then the lower slot 16, enters the bag opening hopper 9, and then flows into the packaging bag. When the weight of the color masterbatch in the packaging bag gradually increases, the limiting cylinder 13, together with the lifting rod 5 and the placement plate 10, moves downward along the sliding rod 3. At this time, the spring 4 is compressed and deformed. Before the weight of the color masterbatch in the packaging bag reaches a certain threshold, the pointer pin 15 outside the insert cylinder 8 moves upward relative to the straight groove 20 inside the sleeve 14. That is, the insert cylinder 8 moves downward with the limiting cylinder 13. When the weight of the color masterbatch in the packaging bag is close to the current uniform setting value, the solenoid valve module 12 closes in advance, cutting off the color masterbatch in the upstream hopper 7. There are still some masterbatches remaining in the sleeve 14. At this time, the placement plate 10 continues to move downward, the spring 4 continues to compress and deform, and the pointer pin 15 enters the spiral groove 21, pushing the sleeve 14 to rotate. The upper groove 17 and the lower groove 16 gradually move away from each other, and the flow of masterbatches in the grooves becomes smaller and smaller until the upper groove 17 and the lower groove 16 are completely misaligned. Then, the addition of masterbatches to the packaging bag is stopped. The conveying mechanism set on both sides of the placement plate 10 of the automatic bag feeding machine base module 1 transfers the masterbatches that have been packaged to the conveyor belt module 11 to complete the unloading. After the bag containing the packaged masterbatches is removed, the placement plate 10 rebounds under the action of the spring 4, and the sleeve 14 rebounds upward. Under the action of the pointer pin 15, the sleeve 14 first rotates and then descends in a straight line, finally aligning the lower groove 16 with the upper groove 17. At this time, the next packaging bag is loaded, and the solenoid valve module 12 is opened to load masterbatches from the hopper 7 into the next bag of masterbatches packaging process.
[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
