It is transported to the construction site in bagged or bulk form and can be used directly after mixing with water. Dry-mixed mortar is widely used in the construction industry, serving as a thin layer for bonding, padding, protection, and decoration, and is extremely common in building and decoration projects.

[0003] When a dry-mixed mortar packaging machine uses a valve bag, an impeller packaging machine exhaust device is required. Chinese utility model patent with announcement number CN208344627U discloses an exhaust device for a valve bag packaging machine, which includes a double-layer feeding nozzle, a vacuum generator, an exhaust pipe, and a control valve.

The two ends of the inner layer are connected to the packaging machine outlet and the valve bag inlet, respectively, to fill the valve bag with material. The two ends of the outer layer are connected to the valve bag inlet and one end of the exhaust pipe, respectively.

[0004] In the process of realizing this application, the technology has at least the following problems: In the automated packaging process, ensuring that the gas inside the packaging bag is effectively discharged is a key step to guarantee product quality and extend shelf life. However, the exhaust device of the packaging machine often lacks adaptability to the shape of the packaging bag and the ability to adjust the impeller speed, resulting in poor exhaust effect and failure to meet the usage requirements. Therefore, an impeller packaging machine exhaust device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an exhaust device for an impeller packaging machine, which has the advantages of high packaging efficiency. It solves the problem that in the automated packaging process of existing valve bag packaging machines, ensuring that the gas inside the packaging bag is effectively discharged is a key step in ensuring product quality and extending shelf life. However, the exhaust devices of these packaging machines often lack adaptability to the shape of the packaging bag and the ability to adjust the impeller speed, resulting in poor exhaust effect and failure to meet the usage requirements.

[0006] In summary, this application provides the following technical solution: an exhaust device for an impeller packaging machine, comprising a base, a mounting bracket fixedly connected to the back of the base, a controller fixedly installed outside the base, and an exhaust box disposed on the upper surface of the base. The base is provided with a compression mechanism extending to its upper surface, and the exhaust box is provided with an exhaust mechanism extending to its outside.

[0007] The extrusion mechanism includes a servo motor fixedly installed outside the base, a bidirectional threaded rod fixedly connected to the output shaft of the servo motor, threaded blocks threadedly connected to the left and right sides outside the bidirectional threaded rod, a connecting block fixedly connected to the top of the threaded blocks, and a clamping plate fixedly connected to the top of the connecting blocks.

[0008] The exhaust mechanism includes a mounting shell fixedly installed inside the exhaust box, an impeller rotatably connected inside the mounting shell, a rotating shaft fixedly connected to the impeller shaft, and a drive mechanism located outside the exhaust box.

[0009] This application, by adopting the above-mentioned technical solution, uses a controller to start a servo motor that drives a bidirectional threaded rod to rotate. This rotation causes two threaded blocks to move closer or further apart, allowing the clamping plates to adjust their spacing via a connecting block. This enables the compression force to be adjusted according to the shape of the packaging bag, ensuring effective gas discharge. Effective gas discharge reduces the risk of bag expansion and rupture, improving packaging quality. Through precise control and flexible adjustment, the exhaust efficiency and packaging quality during the packaging process are improved, while maintenance costs and operational difficulty are reduced, achieving the advantage of high packaging efficiency. The exhaust device of this impeller packaging machine uses a speed-regulating motor started by the controller to drive the transmission gear... The rotation of the transmission gears causes the driven gear, rotating shaft, and impeller to rotate, facilitating impeller speed adjustment. This allows operators to easily control the exhaust process. Precise impeller speed control reduces equipment wear caused by overload or improper operation, extending equipment lifespan. It also ensures consistent exhaust performance for each packaging bag, improving final product consistency. The controller manages the opening and closing of the pneumatic control valve, and the inverted trapezoidal design of the suction hood allows the exhaust mechanism to be adjusted according to the shape and size of the packaging bags, adapting to different packaging needs and increasing the flexibility of the packaging line. This results in high practicality.

[0010] Furthermore, the servo motor is fixedly mounted to the outside of the base by bolts, the servo motor is electrically connected to the controller, and the bidirectional threaded rod is rotatably connected to the inside of the base, with the threads on both sides of the bidirectional threaded rod being opposite.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the servo motor is started by the controller to drive the bidirectional threaded rod to rotate, so that the rotation of the bidirectional threaded rod causes the two threaded blocks to move closer or separate.

[0012] Furthermore, there are two of each of the threaded block, connecting block, and clamping plate. Both clamping plates are solid cuboids, and they are symmetrically distributed on the upper surface of the inner bottom wall of the base.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the spacing can be adjusted by moving the connecting block to drive the clamping plate by bringing the threaded blocks closer or apart.

[0014] Furthermore, the base has an internal movable opening that matches the connecting block, and the outer diameter of the connecting block matches the inner diameter of the movable opening.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by opening a movable port, it is convenient to move the clamping plate.

[0016] Furthermore, a guide shaft is fixedly connected inside the base, and each of the two threaded blocks has a limiting hole adapted to the guide shaft inside, and both threaded blocks are slidably connected to the outside of the guide shaft.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by setting a guide shaft, the stability of the two threaded blocks during linear movement is improved.

[0018] Furthermore, the drive mechanism includes a driven gear fixedly connected to the end of the rotating shaft away from the impeller and a speed-regulating motor fixedly installed outside the exhaust box. A transmission gear that meshes with the driven gear is fixedly connected to the output shaft of the speed-regulating motor.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the speed-regulating motor is started by the controller to drive the transmission gear to rotate, so that the rotation of the transmission gear meshes and drives the driven gear, the rotating shaft and the impeller to rotate.

[0020] Furthermore, an exhaust pipe is fixedly connected to the right side of the exhaust box, a pneumatic control valve is fixedly connected to the bottom of the exhaust box, a connecting pipe is fixedly connected to the input end of the pneumatic control valve, and the bottom end of the connecting pipe is fixedly connected to the air intake hood.

[0021] The beneficial effects of adopting the above-mentioned further solution are: by controlling the opening and closing of the pneumatic control valve through the controller, and by designing the suction hood as an inverted trapezoid, the exhaust mechanism can be adjusted according to the shape and size of the packaging bag.

[0022] Furthermore, a hydraulic cylinder extending to its lower surface is fixedly mounted on the upper surface of the mounting bracket, and the exhaust box is fixedly connected to the output end of the hydraulic cylinder.

[0023] The beneficial effect of adopting the above-mentioned further solution is that the hydraulic cylinder is activated by the controller to extend and retract, thereby moving the exhaust box and the intake hood upward or downward.

[0024] Compared with the prior art, this application provides an exhaust device for an impeller packaging machine, which has the following advantages:

[0025] 1. The exhaust device of this impeller packaging machine uses a controller to start a servo motor that drives a bidirectional threaded rod to rotate. This rotation causes two threaded blocks to move closer or further apart, which in turn adjusts the spacing of the clamping plates via a connecting block. This allows for adjustment of the squeezing force according to the shape of the packaging bag, ensuring that gas is effectively discharged. By effectively discharging gas from the packaging bag, the risk of bag expansion and rupture is reduced, thus improving packaging quality. Through precise control and flexible adjustment, the exhaust efficiency and packaging quality during the packaging process are improved, while maintenance costs and operational difficulty are reduced, achieving the advantage of high packaging efficiency.

[0026] 2. The exhaust device of this impeller packaging machine uses a speed-regulating motor driven by a controller to rotate the transmission gear. This rotation of the transmission gear meshes with the driven gear, rotating shaft, and impeller, facilitating the adjustment of the impeller speed. This allows operators to easily control the exhaust process. Precise control of the impeller speed reduces equipment wear caused by overload or improper operation, extending equipment life.

The controller controls the opening and closing of the pneumatic control valve, and the inverted trapezoidal design of the suction hood allows the exhaust mechanism to be adjusted according to the shape and size of the packaging bags to adapt to different packaging needs. This increases the flexibility of the packaging line, making it highly practical. Attached Figure Description

[0033] Please see Figures 1 to 4The exhaust device for an impeller packaging machine in this embodiment includes a base 1, a mounting bracket 2 fixedly connected to the back of the base 1, a controller 3 fixedly installed outside the base 1, and an exhaust box 4 disposed on the upper surface of the base 1. The base 1 has a pressing mechanism extending to its upper surface inside, and the exhaust box 4 has an exhaust mechanism extending to its outside inside. The pressing mechanism includes a servo motor 5 fixedly installed outside the base 1, a bidirectional threaded rod 6 fixedly connected to the output shaft of the servo motor 5, threaded blocks 7 threadedly connected to the left and right sides of the bidirectional threaded rod 6, a connecting block 8 fixedly connected to the top of the threaded block 7, and a clamping plate 9 fixedly connected to the top of the connecting block 8.

[0034] The servo motor 5 is started by the controller 3, which drives the bidirectional threaded rod 6 to rotate. The rotation of the bidirectional threaded rod 6 causes the two threaded blocks 7 to move closer or further apart. The gap between the clamping plates 9 can be adjusted by the connecting block 8, which can adjust the squeezing force according to the shape of the packaging bag to ensure that the gas is effectively discharged. By effectively discharging the gas inside the packaging bag, the risk of the packaging bag expanding and breaking is reduced, and the packaging quality is improved. Through precise control and flexible adjustment, the exhaust efficiency and packaging quality in the packaging process are improved, while maintenance costs and operation difficulty are reduced, achieving the advantage of high packaging efficiency.

[0035] The servo motor 5 is bolted to the outside of the base 1 and electrically connected to the controller 3. A bidirectional threaded rod 6 is rotatably connected to the inside of the base 1, with opposite threads on both sides. The servo motor 5 offers fast response, allowing for quick start and stop, thus improving operational safety. Effective venting reduces the risk of product contamination during packaging, and automated adjustment minimizes manual intervention, improving production efficiency and overall production line performance. Furthermore, this extrusion mechanism can be easily integrated into existing packaging production lines for automated control.

[0036] Specifically, there are two threaded blocks 7, two connecting blocks 8, and two clamping plates 9. Both clamping plates 9 are solid cuboids and are symmetrically distributed on the upper surface of the inner bottom wall of the base 1. Anti-slip rubber is fixedly connected to the opposite side of each clamping plate 9.

[0037] It should be noted that the base 1 has an internal movable opening that matches the connecting block 8, and the outer diameter of the connecting block 8 matches the inner diameter of the movable opening.

[0038] In addition, a guide shaft 10 is fixedly connected inside the base 1, and each of the two threaded blocks 7 has a limiting hole adapted to the guide shaft 10. Both threaded blocks 7 are slidably connected to the outside of the guide shaft 10. By setting the guide shaft 10, the stability of the two threaded blocks 7 during linear movement is improved.

[0039] Please see Figure 3 and Figure 4 In this embodiment, the exhaust mechanism includes a mounting shell 11 fixedly installed inside the exhaust box 4, an impeller 12 rotatably connected inside the mounting shell 11, a rotating shaft 13 fixedly connected to the shaft of the impeller 12, and a drive mechanism disposed outside the exhaust box 4.

[0040] The drive mechanism includes a driven gear 14 fixedly connected to the end of the rotating shaft 13 away from the impeller 12, and a speed-regulating motor 16 fixedly installed outside the exhaust box 4. A transmission gear 15, meshing with the driven gear 14, is fixedly connected to the output shaft of the speed-regulating motor 16. The controller 3 starts the speed-regulating motor 16, driving the transmission gear 15 to rotate. This rotation of the transmission gear 15 meshes with the driven gear 14, rotating shaft 13, and impeller 12, facilitating the adjustment of the impeller 12's speed. This allows operators to easily control the exhaust process. Precise control of the impeller 12's speed reduces equipment wear caused by overload or improper operation, extending equipment lifespan. It also ensures consistent exhaust performance for each packaging bag, improving the consistency of the final product. The drive mechanism enables precise control of the impeller 12's speed, improving exhaust efficiency and packaging quality while reducing operational difficulty and maintenance costs.

[0041] It should be noted that an exhaust pipe 17 is fixedly connected to the right side of the exhaust box 4, and a pneumatic control valve 18 is fixedly connected to the bottom of the exhaust box 4. A connecting pipe 19 is fixedly connected to the input end of the pneumatic control valve 18, and the bottom end of the connecting pipe 19 is fixedly connected to the suction hood 20. The controller 3 controls the opening and closing of the pneumatic control valve 18, and the suction hood 20 is designed as an inverted trapezoid, so that the exhaust mechanism can be adjusted according to the shape and size of the packaging bag to adapt to different packaging needs, increasing the flexibility of the packaging line and achieving the advantage of high practicality.

[0042] Please see Figure 1 In this embodiment, a hydraulic cylinder 21 extending to its lower surface is fixedly mounted on the upper surface of the mounting bracket 2, and an exhaust box 4 is fixedly connected to the output end of the hydraulic cylinder 21. The controller 3 activates the hydraulic cylinder 21 to extend and retract, causing the exhaust box 4 and the suction hood 20 to move upward or downward, so that the exhaust mechanism can adapt to packaging bags of different sizes and shapes.

[0043] The working principle of the above embodiments is as follows:

[0044] During operation, the packaging machine places the material into the packaging bag and positions the bag between the two clamping plates 9 at the top of the base 1. Then, the controller 3 activates the hydraulic cylinder 21 to extend and retract, causing the exhaust box 4 and the suction hood 20 to move upwards or downwards, bringing the suction hood 20 into contact with the packaging bag. The controller 3 then activates the servo motor 5 to rotate the bidirectional threaded rod 6, causing the two threaded blocks 7 to move closer or further apart. The clamping plates 9 can then be adjusted via the connecting block 8, allowing for adjustment of the squeezing force according to the shape of the packaging bag. This effectively removes gas from the packaging bag, reducing the risk of expansion and rupture, and improving packaging quality. Through precise control and flexible adjustment, the machine improves exhaust efficiency and packaging quality during the packaging process while reducing maintenance costs. This reduces the complexity of operation; the controller 3 starts the speed-regulating motor 16, which drives the transmission gear 15 to rotate. The rotation of the transmission gear 15 meshes with the driven gear 14, the rotating shaft 13, and the impeller 12, making it easy to adjust the speed of the impeller 12. This allows operators to easily control the exhaust process. By precisely controlling the speed of the impeller 12, wear and tear caused by overload or improper operation can be reduced, extending the equipment's lifespan. At the same time, it ensures consistent exhaust performance for each packaging bag, improving the consistency of the final product. The controller 3 controls the opening and closing of the pneumatic control valve 18, and the design of the suction hood 20 as an inverted trapezoid allows the exhaust mechanism to be adjusted according to the shape and size of the packaging bag to adapt to different packaging needs, increasing the flexibility of the packaging line.
