DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0020] A lifting type raw material feeding device, such as Figure 1 , Figure 2 and Figure 3As shown, it includes a moving component 1, a telescopic plate 2, a first cylinder 3, a conveyor belt 4, a support frame 5, a first driving component 6 and a spring 7. The front upper sides of the left and right parts of the moving component 1 are connected with the telescopic plates 2 for telescopically adjusting the height. The moving component 1 includes a moving base and a guide. There are two moving bases. The front sides of the left and right parts of the rear moving base are connected with guides. The front moving bases are slidably connected to the guides. The front upper sides of the left and right parts of the moving component 1 are connected to the first cylinder 3 for driving and adjusting the height of the telescopic plate 2. The telescopic rods of the first cylinder 3 are connected to the upper parts of the adjacent telescopic plates 2. The upper rear side of the moving component 1 is connected with a support frame 5. A conveyor belt 4 for conveying and feeding is wound between the support frame 5 and the upper part of the telescopic plate 2. The upper middle part of the rear of the moving component 1 is connected with the first driving component 6 for driving the conveyor belt 4 to rotate. 6 includes a driving motor, a pulley and a transmission belt. The driving motor is connected to the upper middle side of the rear part of the moving component 1. The output shaft of the driving motor and the upper part of the support frame 5 are both connected with pulleys, and a transmission belt is wound between the pulleys. A spring 7 is connected to the middle part of the moving component 1, and also includes a clamping mechanism 8. The clamping mechanism 8 includes a second driving component 81, a guide rod 82 and a clamping plate 83. The upper middle side of the front part of the moving component 1 is connected to the second driving component 81 for driving clamping. The second driving component 81 includes a double-axis motor and a screw rod. The upper middle side of the front part of the moving component 1 is connected to the double-axis motor, and the output shafts of the double-axis motors are both connected with screw rods. The non-adjacent sides of the middle part of the telescopic plate 2 are connected with guide rods 82 for clamping and guiding. The left and right parts of the second driving component 81 are both threadedly connected with clamping plates 83 for clamping the plastic granule molding machine, and the middle part of the clamping plates 83 are both slidably connected to the adjacent guide rods 82.

[0021] This device can be used when feeding the raw materials of the plastic pellet molding machine. It should be noted that the moving component 1 is first pushed to the feeding position of the plastic pellet molding machine, and then the two first cylinders 3 are started, so that the telescopic rods of the first cylinders 3 drive the adjacent telescopic plates 2 to move upward. At this time, the distance between the front and rear parts of the moving component 1 is reduced, and at the same time, the spring 7 is compressed, so that the front part of the conveyor belt 4 moves upward, and then the second driving component 81 is started, so that the second driving component 81 drives the adjacent clamping plates 83 to slide along the adjacent guide rods 82 to the adjacent side, so that the clamping plates 83 are clamped and connected to the plastic pellet molding machine on the front side, and then the first driving component 6 is started, so that the first driving component 6 drives the conveyor belt 4 to rotate continuously, so that the conveyor belt 4 continuously transports the raw materials to the plastic pellet molding machine. When the feeding process is completed, the conveyor belt 4 is turned on and the feeding is completed. After the clamp is completed, the second driving component 81 is closed, so that the left and right parts of the second driving component 81 both drive the adjacent clamping plates 83 to slide along the adjacent guide rod 82 to the non-adjacent side, thereby making the clamping plates 83 both break away from the clamping connection state to the plastic pellet forming machine, and then the two first cylinders 3 are closed, so that the telescopic rods of the first cylinders 3 both drive the adjacent telescopic plates 2 to move downward and reset. At this time, the distance between the front and rear parts of the moving component 1 is expanded and reset, and the spring 7 is retracted and reset, thereby making the front part of the conveyor belt 4 move downward and reset, and then the moving component 1 can be moved to the designated storage position. In summary, through the cooperation between the second driving component 81 and the clamping plate 83, the plastic pellet forming machine and the loading position are clamped and connected, so that the raw materials can stably enter the plastic pellet forming machine during the loading process, thereby improving the stability of raw material loading.

[0022] like Figure 1 and Figure 4 As shown, a stabilizing mechanism 9 is also included, and the stabilizing mechanism 9 includes a fixed seat 91, a second cylinder 92 and a stabilizing block 93. The fixed seat 91 is connected to the left and right sides of the middle of the rear part of the moving component 1, and the second cylinder 92 is connected to the upper side of the middle part of the fixed seat 91. The telescopic rods of the second cylinder 92 pass through the adjacent fixed seats 91 and are connected to the stabilizing block 93 for stabilizing the limited moving component 1, and the lower edge of the stabilizing block 93 is connected to a scratch-resistant surface.

[0023] It should be noted that after the mobile component 1 is moved to the plastic pellet molding machine for feeding, the two second cylinders 92 are started, so that the telescopic rods of the second cylinders 92 drive the adjacent stabilizing blocks 93 to move downward, and then the stabilizing blocks 93 limit the rear part of the mobile component 1 to prevent the rear part of the mobile component 1 from moving randomly, and then the splint 83 can be used to clamp the plastic pellet molding machine. After the feeding is completed, the two second cylinders 92 are closed, so that the telescopic rods of the second cylinders 92 drive the adjacent stabilizing blocks 93 to move upward and reset. At this time, the rear part of the mobile component 1 is out of the limit locking state, and the mobile component 1 can be moved to other positions. In summary, through the cooperation between the second cylinder 92 and the stabilizing block 93, the rear part of the mobile component 1 is locked and limited, which facilitates the stable feeding of the conveyor belt 4 and facilitates the clamping connection between the front part of the mobile component 1 and the plastic pellet molding machine.
