Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a feeding control device for thermoplastic elastomers. Background Technology

[0002] Thermoplastic elastomers (TPE / TPR), also known as synthetic rubber or synthetic materials, possess the excellent properties of traditional cross-linked vulcanized rubber, such as high elasticity, aging resistance, and oil resistance, while also having the advantages of ordinary plastics, such as convenient processing and a wide range of processing methods. When packaging thermoplastic elastomer granules, quantitative bagging is required.

[0003] In the process of packaging thermoplastic elastomers, workers need to quantitatively dispense the thermoplastic elastomers into bags. In the existing technology, the quantitative measurement is entirely based on manual visual inspection, which results in low accuracy and easily leads to inconsistent quantities of thermoplastic elastomer particles after packaging. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a thermoplastic elastomer feeding control device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a thermoplastic elastomer feeding control device, including a discharge hopper and a support plate located below the discharge hopper, a rotating rod rotatably disposed on the upper surface of the support plate, a rotating disk fixedly disposed on the upper surface of the rotating rod, two mutually symmetrical first discharge ports being opened through the upper surface of the rotating disk, two mutually symmetrical first storage pipes being disposed below the rotating disk, the first discharge ports being directly opposite the first storage pipes, and a driving component for driving the rotating disk to rotate being disposed on the support plate.

[0006] By adopting the above technical solution, the produced thermoplastic elastomer enters the first storage tube through the discharge hopper and the first discharge port. After the thermoplastic elastomer enters the first storage tube, the operator needs to activate the drive assembly, which in turn rotates the rotating rod, causing the rotating disk to rotate 180 degrees (during the rotation, the discharge hopper is not directly opposite the first discharge port). Subsequently, the thermoplastic elastomer in the first storage tube, after rotating 180 degrees, falls into the bag. At this time, the discharge hopper is directly opposite another first discharge port, causing the thermoplastic elastomer to fall into another first storage tube. During this process, the thermoplastic elastomer can be quantitatively filled into the bag through the first storage tube, thereby reducing the probability of inconsistent thermoplastic elastomer quantities during packaging.

[0007] Furthermore, the drive assembly includes a motor fixedly mounted on the bottom surface of the support plate, a drive gear fixedly mounted on the end of the motor output shaft, and a driven gear sleeved on the outer wall of the rotating rod. The driven gear is fixed to the rotating rod. The drive gear is an incomplete gear. The drive gear and the driven gear mesh with each other. The gear ratio of the drive gear to the driven gear is 1:2.

[0008] By adopting the above technical solution, when the operator needs to rotate the turntable 180 degrees, the operator needs to start the motor, which in turn causes the motor output shaft to rotate 360 ​​degrees. This causes the drive gear to rotate 360 ​​degrees under the action of the motor output shaft, which in turn causes the driven gear to rotate 180 degrees under the action of the drive gear (e.g., Figure 3 As shown, the ratio of the number of teeth of the driving gear to the number of teeth of the driven gear is 1:2, so that the rotating rod rotates 180 degrees under the action of the driven gear, and then the rotating disk rotates 180 degrees under the action of the rotating rod, thereby reducing the difficulty for the workers to rotate the rotating disk and thus reducing the difficulty of the workers' work.

[0009] Furthermore, a rotating groove is provided on the upper surface of the support plate, the rotating rod is rotatably connected to the rotating groove, an annular groove is provided on the inner wall of the rotating groove, an annular block is rotatably arranged in the annular groove, and the annular block is fixed to the rotating rod.

[0010] By adopting the above technical solution, when the rotating rod rotates, the annular block rotates synchronously with the rotating rod under the action of the rotating rod. During this process, the annular block limits the rotating rod, thereby reducing the probability of the rotating rod moving up and down, thus improving the stability of the device.

[0011] Furthermore, a slider is sleeved on the outer wall of the rotating rod, the slider is slidably connected to the rotating rod, a connecting tube is rotatably provided on the upper surface of the slider, a connecting plate is fixedly provided on the upper surface of the connecting tube, the rotating rod passes through the connecting tube and the connecting plate and is rotatably connected to them, a second discharge port is provided through the upper surface of the connecting plate, and a second storage tube is fixedly provided in each of the two second discharge ports, the outer wall of the first storage tube is slidably connected to the inner wall of the second storage tube.

[0012] By adopting the above technical solution, when the operator needs to adjust the amount of thermoplastic elastomer falling each time, the operator needs to slide the slider up or down, which in turn causes the connecting pipe and connecting plate to slide up or down under the action of the slider. This causes the second storage pipe to move up or down under the action of the connecting plate. During use, the thermoplastic elastomer in the first storage pipe falls into the second storage pipe, thus filling both the first and second storage pipes. When the operator slides the slider, the space inside the first and second storage pipes decreases, thereby adjusting the amount of thermoplastic elastomer falling each time, thus improving the practicality of the device. In addition, when the rotating disk rotates, the first storage pipe, the second storage pipe, the connecting plate, and the connecting pipe rotate synchronously, without affecting the rotation of the rotating disk.

[0013] Furthermore, an arc-shaped baffle plate is fitted on the outer wall of the connecting pipe. The upper surface of the baffle plate abuts against the bottom surface of the second storage pipe directly below the discharge hopper. The baffle plate is rotatably connected to the connecting pipe. A connecting rod is fixedly installed on the bottom surface of the baffle plate. The bottom surface of the connecting rod is fixed to the upper surface of the support plate.

[0014] By adopting the above technical solutions, such as Figure 1 and Figure 2 As shown, the upper surface of the baffle plate abuts against the bottom surface of the second storage pipe directly below the discharge hopper, reducing the probability of leakage of thermoplastic elastomer during the storage process of the first and second storage pipes, thereby improving the stability of the device.

[0015] Furthermore, a limiting groove is formed on the upper surface of the slider, and a limiting ring is rotatably arranged in the limiting groove, with the limiting ring and the connecting pipe being fixed to each other.

[0016] Furthermore, the diameter of the limiting ring gradually increases from top to bottom.

[0017] By adopting the above technical solution, the probability of the limiting ring connecting pipe separating from the slider when rotating is reduced, thereby improving the stability of the device.

[0018] Furthermore, fixing bolts are fixedly installed on the side wall of the slider.

[0019] By adopting the above technical solution, the fixing bolts reduce the difficulty for workers to fix the slider, thereby reducing the difficulty of their work.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. In this application, the produced thermoplastic elastomer enters the first storage tube through the discharge hopper and the first discharge port. After the thermoplastic elastomer enters the first storage tube, the operator needs to activate the drive assembly, which causes the rotating rod to rotate under the action of the drive assembly, thereby causing the rotating disk to rotate 180 degrees (during the rotation of the rotating disk, the discharge hopper is not directly opposite the first discharge port). Subsequently, the thermoplastic elastomer in the first storage tube, which has rotated 180 degrees, falls into the bag. At this time, the discharge hopper is directly opposite another first discharge port, causing the thermoplastic elastomer to fall into another first storage tube. During this process, the thermoplastic elastomer can be quantitatively filled into the bag through the first storage tube, thereby reducing the probability of inconsistent thermoplastic elastomer quantities during packaging.

[0022] 2. In this application, when the operator needs to rotate the turntable 180 degrees, the operator needs to start the motor, which in turn causes the motor output shaft to rotate 360 ​​degrees. This causes the drive gear to rotate 360 ​​degrees under the action of the motor output shaft, which in turn causes the driven gear to rotate 180 degrees under the action of the drive gear (e.g., Figure 3 As shown, the ratio of the number of teeth of the driving gear to the driven gear is 1:2, which causes the rotating rod to rotate 180 degrees under the action of the driven gear, and then causes the rotating disk to rotate 180 degrees under the action of the rotating rod, thereby reducing the difficulty for the workers to rotate the rotating disk and thus reducing the difficulty of the workers' work.

[0023] 3. In this application, when the rotating rod rotates, the annular block rotates synchronously with the rotating rod under the action of the rotating rod. During this process, the annular block limits the rotating rod, thereby reducing the probability of the rotating rod moving up and down, thus improving the stability of the device.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-3 As shown in the figure, this application discloses a thermoplastic elastomer feeding control device, including a discharge hopper 1, a support plate 11, a rotating rod 12, a rotating disk 13, a first storage tube 15, a drive assembly 2, a slider 4, a connecting pipe 41, a connecting disk 42, a second storage tube 44, a baffle plate 5, and a connecting rod 51. The support plate 11 is a rectangular plate structure and is located below the discharge hopper 1. The rotating rod 12 is a cylindrical rod structure with a vertical axis and is rotatably mounted on the upper surface of the support plate 11. The rotating disk 13 is a cylindrical plate structure with its axis coinciding with the axis of the rotating rod 12 and is fixedly mounted on the upper surface of the rotating rod 12. Two mutually symmetrical first discharge ports 14 are provided through the upper surface of the rotating disk 13. The first storage tube 15 is a cylindrical tube structure with a vertical axis. Two first storage tubes 15 are provided and symmetrically arranged below the rotating disk 13, with the first discharge ports 14 facing each other.

[0030] The completed thermoplastic elastomer enters the first storage tube 15 through the discharge hopper 1 and the first discharge port 14. After the thermoplastic elastomer enters the first storage tube 15, the operator needs to activate the drive assembly 2, which causes the rotating rod 12 to rotate, thereby causing the rotating disk 13 to rotate 180 degrees (during the rotation of the rotating disk 13, the discharge hopper 1 is not directly opposite the first discharge port 14). Subsequently, the thermoplastic elastomer in the first storage tube 15, which has rotated 180 degrees, falls into the bag. At this time, the discharge hopper 1 is directly opposite another first discharge port 14, causing the thermoplastic elastomer to fall into another first storage tube 15. During this process, the thermoplastic elastomer can be quantitatively filled into the bag through the first storage tube 15, thereby reducing the probability of inconsistent thermoplastic elastomer quantities during packaging.

[0031] The drive assembly 2 is mounted on the support plate 11 and is used to drive the rotating disk 13 to rotate. The drive assembly 2 includes a motor 21, a drive gear 22, and a driven gear 23. The motor 21 is fixedly mounted on the bottom surface of the support plate 11, and its output shaft axis is vertical. The drive gear 22 is fixedly mounted on the end of the output shaft of the motor 21, and its axis coincides with the axis of the output shaft of the motor 21. The drive gear 22 is an incomplete gear. The driven gear 23 is sleeved on the outer wall of the rotating rod 12, and its axis coincides with the axis of the rotating rod 12. The driven gear 23 and the rotating rod 12 are fixed to each other. The drive gear 22 and the driven gear 23 mesh with each other, and the gear ratio of the drive gear 22 to the driven gear 23 is 1:2.

[0032] When the operator needs to rotate the turntable 13 180 degrees, the operator needs to start the motor 21, which will cause the output shaft of the motor 21 to rotate 360 ​​degrees. This will cause the drive gear 22 to rotate 360 ​​degrees under the action of the output shaft of the motor 21, and in turn, cause the driven gear 23 to rotate 180 degrees under the action of the drive gear 22 (e.g., Figure 3 As shown, the ratio of the number of teeth of the driving gear 22 to the number of teeth of the driven gear 23 is 1:2, so that the rotating rod 12 rotates 180 degrees under the action of the driven gear 23, and then the rotating disk 13 rotates 180 degrees under the action of the rotating rod 12, thereby reducing the difficulty for the workers to rotate the rotating disk 13 and thus reducing the difficulty of the workers' work.

[0033] To improve the stability of the device, a rotating groove 3 is formed on the upper surface of the support plate 11. The rotating rod 12 is rotatably connected to the rotating groove 3. An annular groove 31 is formed on the inner wall of the rotating groove 3, and an annular block 32 is rotatably disposed in the annular groove 31. The annular block 32 is fixed to the rotating rod 12. When the rotating rod 12 rotates, the annular block 32 rotates synchronously with the rotating rod 12 under the action of the rotating rod 12. During this process, the annular block 32 limits the rotation of the rotating rod 12, thereby reducing the probability of the rotating rod 12 moving up and down, thus improving the stability of the device.

[0034] The slider 4 is a rectangular block structure, fitted onto the outer wall of the rotating rod 12, and slidably connected to the rotating rod 12. The connecting pipe 41 is a cylindrical structure, its axis coinciding with the axis of the rotating rod 12, and rotatably mounted on the upper surface of the slider 4. The connecting plate 42 is a cylindrical plate structure, its axis coinciding with the axis of the rotating rod 12, and fixedly mounted on the upper surface of the connecting pipe 41. The rotating rod 12 passes through the connecting pipe 41 and the connecting plate 42 and is rotatably connected to them. A second discharge port 43 is provided through the upper surface of the connecting plate 42. The second storage pipe 44 is a cylindrical structure, its axis coinciding with the axis of the first storage pipe 15. Two first storage pipes 15 are provided and fixedly mounted in the two second discharge ports 43 respectively, and the outer wall of the first storage pipe 15 is slidably connected to the inner wall of the second storage pipe 44.

[0035] When the operator needs to adjust the amount of thermoplastic elastomer falling each time, they need to slide slider 4 up or down. This causes connecting pipe 41 and connecting plate 42 to slide up or down under the action of slider 4, thereby causing the second storage pipe 44 to move up or down under the action of connecting plate 42. During use, the thermoplastic elastomer in the first storage pipe 15 will fall into the second storage pipe 44, thus filling both the first and second storage pipes 15 and 44 with thermoplastic elastomer. When the operator slides slider 4, the space inside the first and second storage pipes 15 and 44 will decrease, thereby adjusting the amount of thermoplastic elastomer falling each time, thus improving the practicality of the device. In addition, when the rotating disk 13 rotates, the first storage pipe 15, the second storage pipe 44, the connecting plate 42, and the connecting pipe 41 will rotate synchronously without affecting the rotation of the rotating disk 13.

[0036] The baffle plate 5 has an arc-shaped cross-section and is fitted onto the outer wall of the connecting pipe 41. The upper surface of the baffle plate 5 abuts against the bottom surface of the second storage pipe 44 directly below the discharge hopper 1. The baffle plate 5 is rotatably connected to the connecting pipe 41. The connecting rod 51 is fixedly installed on the bottom surface of the baffle plate 5, and the bottom surface of the connecting rod 51 is fixed to the upper surface of the support plate 11.

[0037] like Figure 1 and Figure 2 As shown, the upper surface of the baffle plate 5 abuts against the bottom surface of the second storage pipe 44 directly below the discharge hopper 1, reducing the probability of leakage of thermoplastic elastomer during the storage process of the first storage pipe 15 and the second storage pipe 44, thereby improving the stability of the device.

[0038] To improve the stability of the device, a limiting groove 6 is formed on the upper surface of the slider 4, and a limiting ring 61 is rotatably installed in the limiting groove 6. The limiting ring 61 is fixed to the connecting pipe 41, and the diameter of the limiting ring 61 gradually increases from top to bottom. This reduces the probability of the limiting ring 61 separating from the slider 4 when the connecting pipe 41 rotates, thereby improving the stability of the device.

[0039] To reduce the difficulty of the workers' work, fixing bolts 7 are fixedly installed on the side wall of slider 4. Fixing bolts 7 reduce the difficulty for workers to fix slider 4, thereby reducing the difficulty of the workers' work.

[0040] The operating principle of the thermoplastic elastomer feeding control device in this embodiment is as follows: The produced thermoplastic elastomer enters the first storage pipe 15 through the discharge hopper 1 and the first discharge port 14. After the thermoplastic elastomer enters the first storage pipe 15, the operator needs to activate the drive assembly 2, which causes the rotating rod 12 to rotate, thereby causing the rotating disk 13 to rotate 180 degrees (during the rotation of the rotating disk 13, the discharge hopper 1 is not directly opposite the first discharge port 14). Subsequently, the thermoplastic elastomer in the first storage pipe 15, after rotating 180 degrees, falls into the bag. At this time, the discharge hopper 1 is directly opposite another first discharge port 14, causing the thermoplastic elastomer to fall into another first storage pipe 15. During this process, the thermoplastic elastomer can be quantitatively loaded into the bag through the first storage pipe 15, thereby reducing the probability of inconsistent quantities of thermoplastic elastomer during packaging.

[0041] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
