Description

Technical Field

[0001] The utility model belongs to the technical field of granulating machinery, in particular to an anti-blocking device for a material outlet of a granulating machine. Background Art

[0002] A granulator is a molding machine that can make materials into specific shapes. After mixing, the powder is first heated at high temperature, and then extruded by a twin screw to make the powder into flakes or granules. Then, it is crushed by a crusher to obtain granules of specific shapes. The granules are then cooled by a heat dissipation device and finally discharged through the discharge port on the discharge hopper (discharge barrel). At present, when the discharge volume is large, the material is prone to sticking together, causing discharge blockage. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0025] like Figures 1 to 3As shown: This embodiment provides a device for preventing the discharge port of a granulator from being blocked. The granulator includes a machine body and a feed hopper 1 and a discharge barrel 2 arranged on the machine body. The side wall of the discharge barrel is provided with a discharge port. The device for preventing the blocking includes a discharge plate 3 and a fixed plate 4 fixed at the discharge port. The fixed plate is located above the discharge plate. A material-discharging mechanism is provided on the fixed plate. The material-discharging mechanism includes a material-discharging frame 5, a belt transmission mechanism installed on the material-discharging frame, and a plurality of material-discharging parts arranged at intervals and driven to circulate and move by the belt transmission mechanism. The belt transmission mechanism includes a transmission roller 10 arranged on both sides and rotatably assembled with the material-discharging frame, a transmission belt 6 installed between the two transmission rollers, and a motor 11 driving one of the transmission rollers to rotate. The material-discharging part includes a mounting seat 7 rotatably assembled with the transmission belt, a rubber rod mounting frame 8 rotatably assembled with the mounting seat, and a rubber rod 9 rotatably assembled with the rubber rod mounting frame.

[0026] During specific use, the motor 11 is turned on, the motor 11 drives the transmission roller 10 to rotate, the transmission roller 10 drives the transmission belt 6 to move back and forth, and the transmission belt 6 synchronously drives the mounting seat 7, the rubber rod mounting frame 8 and the rubber rod 9 to move back and forth. The rubber rod contacts the material and starts to rotate under the resistance of the material, thereby giving the material a lateral force, so that the material continues to roll during the discharging process, thereby gradually spreading the accumulated material to avoid material blockage.

[0027] As a further improvement to the above technical solution, the material-dispensing mechanism is connected to the fixed plate through a lifting mechanism. In this embodiment, the lifting mechanism includes a lifting body arranged on both sides and an adjusting mechanism for driving the lifting body to lift and lower. The lifting body includes a vertical rod 12 and a threaded rod 13. The bottom of the vertical rod is fixedly connected to the material-dispensing frame. The vertical rod passes through the fixed plate and is slidably assembled with the fixed plate. The threaded rod is fixedly connected to the top of the vertical rod. A threaded sleeve 14 is matched and sleeved on the threaded rod. A driven gear 15 is fixedly sleeved on the threaded sleeve. The two driven gears are linked through the adjusting mechanism. The adjusting mechanism includes a rotating shaft 17 arranged on both sides and rotatably assembled with the fixed plate, a driving gear 16 fixedly mounted on the rotating shaft and meshing with the driven gear on the corresponding side, a pulley 18 fixedly mounted on the rotating shaft, a belt 19 installed between the two pulleys, and a driving wheel 20 meshing with the belt and driving the belt to rotate; a driving seat 22 is fixedly arranged on the fixed plate, a driving shaft 21 is rotatably mounted on the driving seat, and the driving wheel is fixedly sleeved and assembled with the driving shaft. The end of the driving shaft away from the driving wheel is provided with a knob 23. The driven gear is supported and arranged on the fixed plate by a supporting member, and other supporting methods can also be adopted, which is the prior art and will not be described in detail.

[0028] During specific use, the knob 23 is turned, and the knob 23 drives the driving shaft 21 to rotate, and then drives the belt to reciprocate through the driving wheel. The belt drives the pulleys, the rotating shaft and the driving gear at both ends to rotate synchronously, and then drives the corresponding driven gear and the threaded sleeve to rotate synchronously through the driving gear. When the threaded sleeve 14 rotates, the screw transmission principle is used to drive the threaded rod 13 to rise and fall, and then the vertical rod can be used to drive the material dispensing frame to rise and fall, so that the height of the rubber rod can be adjusted. When discharging materials of different particle sizes, the rubber rod can be adjusted to a suitable height to avoid the material being squeezed.

[0029] In particular, the outside of the rubber rod is coated with an antistatic layer to prevent the material from adhering to the rubber rod 9 due to friction adsorption when being rotated, wherein the antistatic layer is coated with a copper layer.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
