Description

Technical Field

[0001] The utility model relates to the technical field of chemical raw material processing, in particular to an automatic quantitative filling device for acrylic resin. Background Art

[0002] Currently, acrylic resin filling generally uses online quantitative filling, which involves placing an electronic scale or floor scale below the mixing kettle. When the reading on the scale or floor scale reaches a preset value, the solenoid valve at the mixing kettle outlet automatically closes. Large acrylic resin drums typically hold 200L (international standard), and a drum filled with acrylic resin weighs 190kg. Manually removing the drums from the scale or floor scale increases labor intensity and reduces filling efficiency. Utility Model Content

[0003] The utility model aims to provide an automatic quantitative filling device for acrylic resin which can automatically perform filling and subsequent transport assembly, reduce the use of staff, reduce costs and improve efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] It includes a base, a conveyor belt is fixed on the base, a resin discharge barrel fixed on the base is provided above the conveyor belt, and a resin receiving barrel for resin filling, a feed pipe is fixed on the resin receiving barrel, the conveyor belt is provided with a through groove, the base is slidably connected with a guide rod, a supporting plate is fixed to the end of the guide rod away from the base, a number of stacked bottom support plates are placed on the supporting plate, the bottom support plates can enter the conveyor belt along the through groove, a lifting control part is provided at the bottom of the supporting plate, a material guide elbow is connected to the bottom of the resin discharge barrel, and a docking piece is fixed to the end of the material guide elbow away from the resin discharge barrel, and the docking piece is used to automatically dock with the feed pipe on the resin receiving barrel.

[0006] Furthermore, a pressure sensor is embedded inside the upper surface of the bottom support plate, and the pressure sensor is connected to the conveyor belt electrical signal.

[0007] Furthermore, a first cylinder is fixed inside the bottom support plate, and the first cylinder is arranged along the four corners of the bottom support plate. A clamping positioning rod is fixed to the output end of each first cylinder, and the clamping positioning rod is slidably connected to the inside of the bottom support plate.

[0008] By adopting the above technical solution, the clamping positioning rod can be extended when driven by the first cylinder and clamped on the resin receiving barrel, ensuring that the bottom support plate and the resin receiving barrel move synchronously, which is convenient for subsequent transportation.

[0009] Furthermore, the lifting control component includes a second cylinder fixed at the bottom of the supporting plate, and also includes a first support plate fixed on the base. A first laser beam switch is fixed on the side of the first support plate. The first laser beam switch is connected in series with the second cylinder, and the first laser beam switch is connected in series with the first cylinder.

[0010] By adopting the above technical solution, if a resin receiving barrel is detected passing through, the first laser beam switch triggers an electrical signal to control the second cylinder to open, and the uppermost bottom support plate is moved above the conveyor belt, flush with the surface of the through groove. After the resin receiving barrel continues to move, the first laser beam switch does not generate an electrical signal, and the second cylinder maintains its position unchanged, thereby continuously supplying the bottom support plate, so that the resin receiving barrel and the bottom support plate are used in combination, which is convenient for moving the resin receiving barrel after it is fully loaded.

[0011] Furthermore, the docking member includes a fixed tube fixed to the side of the feed tube, an annular baffle threadedly connected to the interior of the fixed tube, a plurality of latches fixed to the side of the fixed tube, gears meshing with the sides of the latches, and a servo motor connected to the gears.

[0012] By adopting the above technical solution, the second laser beam switch can control the forward and reverse rotation of the servo motor, and then when the feed tube on the resin receiving barrel moves to the material guide bend, the annular baffle can be driven downward to cover and seal the connection between the feed tube and the material guide bend, which facilitates resin filling and does not require additional staff to participate in the docking.

[0013] In summary, the beneficial technical effects of the present invention are:

[0014] 1. A lifting control unit is used. If a resin barrel is detected passing through, the first laser beam switch triggers an electrical signal, controlling the second cylinder to open, moving the uppermost bottom plate to above the conveyor belt and flush with the surface of the through-channel. After the resin barrel continues to move, the first laser beam switch does not generate an electrical signal, and the second cylinder maintains its position, thereby continuously supplying the bottom plate. The resin barrel and the bottom plate are used together, making it easy to move the resin barrel after it is fully loaded. Filling and subsequent movement can be automatically performed, reducing staff usage, reducing costs, and improving efficiency.

[0015] 2. A second laser beam switch is used. The second laser beam switch can control the forward and reverse rotation of the servo motor. When the feed pipe on the resin receiving barrel moves to the material guide elbow, it can drive the annular baffle to move down to cover and seal the connection between the feed pipe and the material guide elbow, making resin filling more convenient and eliminating the need for additional staff to participate in the docking.

[0016] 3. A clamping positioning rod is used. The clamping positioning rod can be extended when driven by the first cylinder and clamped on the resin receiving barrel to ensure that the bottom plate and the resin receiving barrel move synchronously, which is convenient for subsequent transportation.

DETAILED DESCRIPTION

[0022] The present invention will be described in further detail below with reference to the accompanying drawings.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-3The utility model provides a technical solution: it includes a base 1, a conveyor belt 2 is fixed on the base 1, a resin discharge barrel 3 fixed on the base 1 is provided above the conveyor belt 2, and also includes a resin receiving barrel 4 for resin filling, and a feeding pipe 5 is fixed on the resin receiving barrel 4. The conveyor belt 2 is provided with a through groove 6, and a guide rod 7 is slidably connected to the base 1. A carrying plate 8 is fixed to the end of the guide rod 7 away from the base 1, and a plurality of stacked bottom supporting plates 9 are placed on the carrying plate 8. The bottom supporting plates 9 can enter the conveyor belt 2 along the through groove 6. A lifting control part is provided at the bottom of the carrying plate 8. The bottom of the resin discharge barrel 3 is connected to a material guide elbow 10, and a docking piece is fixed to the end of the material guide elbow 10 away from the resin discharge barrel 3. The docking piece is used to automatically dock the feeding pipe 5 on the resin receiving barrel 4.

[0025] Among them, a pressure sensor 11 is embedded inside the upper surface of the bottom support plate 9, and the pressure sensor 11 is electrically connected to the conveyor belt 2. The threshold of the pressure sensor 11 is set to the full load weight of the resin receiving barrel 4. Then, after the resin receiving barrel 4 is fully loaded, the pressure sensor 11 excites an electrical signal, and based on the existing PLC control system, controls the drive of the conveyor belt 2, so that the next resin receiving barrel 4 enters the conveyor belt 2.

[0026] A first cylinder 12 is fixed inside the bottom supporting plate 9 . The first cylinder 12 is arranged along the four corners of the bottom supporting plate 9 . A clamping positioning rod 13 is fixed to the output end of each first cylinder 12 . The clamping positioning rod 13 is slidably connected to the inside of the bottom supporting plate 9 .

[0027] The lifting control component includes a second cylinder 14 fixed at the bottom of the supporting plate 8, and also includes a first support plate 15 fixed on the base 1. A first laser beam switch 16 is fixed on the side of the first support plate 15. The first laser beam switch 16 is connected in series with the second cylinder 14, and the first laser beam switch 16 is connected in series with the first cylinder 12.

[0028] Among them, the transmitting end and the receiving end of the first laser beam switch 16 are respectively located on two oppositely arranged first support plates 15, and the two are used to detect whether a resin receiving barrel 4 passes through. If a resin receiving barrel 4 is detected to pass through, an electrical signal is triggered to control the first cylinder 12 and the second cylinder 14 to open at the same time. The second cylinder 14 controls the supporting plate 8 to rise, and moves the uppermost bottom support plate 9 to the top of the conveyor belt 2, flush with the surface of the through groove 6. Then, as the resin receiving barrel 4 moves to the bottom of the resin receiving barrel 4, the first cylinder 12 opens and drives the clamping positioning rod 13 to rise, clamping it on the side of the resin receiving barrel 4, fixing the resin receiving barrel 4 while keeping the resin receiving barrel 4 and the bottom support plate 9 moving synchronously. After the resin receiving barrel 4 continues to move, the first laser beam switch 16 does not generate an electrical signal, and the second cylinder 14 maintains its position unchanged, thereby continuously supplying the bottom support plate 9, so that the resin receiving barrel 4 and the bottom support plate 9 are used in combination, which is convenient for moving the resin receiving barrel 4 after it is fully loaded.

[0029] Among them, the docking part includes a fixed tube 17 fixed on the side of the feed pipe 5, the internal thread of the fixed tube 17 is connected to a ring baffle 19, a number of teeth 18 are fixed on the side of the fixed tube 17, and the side of the teeth 18 is engaged with a gear 20, the gear 20 is connected to a servo motor 21, and the servo motor 21 is fixed on the side of the guide elbow 10.

[0030] A second laser beam switch 23 is provided on the side of the feed tube 5 , a second support plate 22 is fixed on the base 1 , the second laser beam switch 23 is fixed on the side of the second support plate 22 , and the second laser beam switch 23 is electrically connected to the servo motor 21 .

[0031] As the resin receiving barrel 4 continues to rotate, the feed tube 5 gradually moves between the second laser beam switch 23, thereby blocking its laser. At this time, the second laser beam switch 23 triggers an electrical signal, and the second laser beam switch 23 is in a high level state, thereby driving the servo motor 21 to rotate. As the servo motor 21 is turned on, its driving gear 20 rotates, driving the fixed tube 17 to rotate, and the annular baffle 19 is threadedly connected to the fixed tube 17, so that the annular baffle 19 can move up and down. In this embodiment, the forward rotation of the servo motor 21 causes the annular baffle 19 to move downward, thereby covering and sealing the contact point between the feed tube 5 and the guide elbow 10, and starting filling. After the filling is completed, the conveyor belt 2 continues to rotate, and the second laser beam switch is at a low level again, then the servo motor 21 reverses, and drives the annular baffle 19 to move upward.

[0032] The working principle of the present utility model is as follows: during actual operation, the second laser beam switch 23 and the pressure sensor 11 jointly control the conveyor belt 2. The second laser beam switch 23 and the pressure sensor 11 are connected in series, wherein the second laser beam switch 23 is equivalent to a diode. When the pressure sensor 11 acts, the conveyor belt 2 is kept rotating. When the second laser beam switch 23 is at a high level, the conveyor belt 2 is kept stopped. In addition, during operation, the conveyor belt 2 is kept normally open.
