First transmission wheels are provided at the front and rear output ends of the double-shaft motor. Fixed shafts are symmetrically provided at the front and rear ends of the cylinder body. Second transmission wheels are rotatably connected to the outer sides of the fixed shafts. The second transmission wheels and the first transmission wheels at the upper and lower positions are driven by a belt. Eccentric rods are provided at the edges of the ends of the second transmission wheels away from the cylinder body. Flat rings are sleeved on the outer sides of the eccentric rods. Cross bars are symmetrically provided at the left and right ends of the flat rings. Limiting frames that match the cross bars are symmetrically provided on the left and right sides of the front and rear ends of the cylinder body. First baffles and second baffles are movably connected in an up-and-down staggered manner to the left and right side walls of the cylinder body. A first C-shaped rod is provided between the first baffle on the left and the cross bar on the left front side. A second C-shaped rod is provided between the second baffle on the right and the cross bar on the right front side. A third C-shaped rod is provided between the second baffle on the left and the cross bar on the left rear side. A fourth C-shaped rod is provided between the first baffle on the right and the cross bar on the right rear side.

[0005] Compared with the prior art, the beneficial effects of the utility model are as follows: The plastic pipe moves from top to bottom inside the cylinder body. There are first baffles and second baffles arranged alternately up and down inside the cylinder body. The baffles are symmetrically arranged left and right and can be opened and closed. By alternately opening and closing the first baffle and the second baffle, the pipe fittings in the cylinder body can move down layer by layer and one by one in the cylinder body. The double-shaft motor drives the front and rear relative transmission wheels to rotate synchronously. The eccentric rods on the transmission wheels rotate to drive components such as the baffles to move, enabling the first baffle and the second baffle to be alternately opened and closed. The opening and closing of the first baffle and the second baffle enable the pipe fittings in the cylinder body to fall one by one and be discharged, reducing the impact on the falling pipe fittings, so as to facilitate the processing of the discharged pipe fittings. The discharge frequency of the pipe fittings is controlled by controlling the rotation speed of the double-shaft motor. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0010] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0011] Please refer to Figure 1-3, the present utility model provides a technical solution: a plastic pipe blanking device, including a cylinder body 1, a hopper 2 is provided at the upper end of the cylinder body 1, a guide plate 3 is provided at the lower end of the cylinder body 1, the cylinder body 1 is vertically through, and the pipe fittings can pass through the cylinder body 1 from top to bottom. The hopper 2 is fixed at the upper end of the cylinder body 1, and the pipe fittings are cached through the hopper 2 and enter the cylinder body 1 from the upper end. The guide plate 3 is fixed at the lower end of the cylinder body 1, and the pipe fittings discharged from the lower end of the cylinder body 1 can be discharged from the device along the guide plate 3. A double-shaft motor 4 is provided at the lower end of the guide plate 3, and a first transmission wheel 5 is provided at the front and rear output ends of the double-shaft motor 4. The double-shaft motor 4 is fixed at the lower end of the guide plate 3, and the two output ends of the double-shaft motor 4 face the front and rear sides respectively. The first transmission wheel 5 is fixed on the two output ends of the double-shaft motor 4. The output end of the double-shaft motor 4 can rotate unidirectionally at a specific speed, and a suitable existing device can be selected according to the situation. The double-shaft motor 4 is connected to an external device and is powered and controlled by the outside. Fixed shafts are symmetrically provided at the front and rear ends of the cylinder body 1, and a second transmission wheel 6 is rotatably connected to the outside of the fixed shaft. The second transmission wheels 6 that are opposite up and down are driven by a belt between the first transmission wheel 5. The two fixed shafts are fixed at the front and rear ends of the cylinder body 1. The second transmission wheel 6 is sleeved on the outside of the fixed shaft and can rotate on it. A protruding and recessed matching method can be adopted between the fixed shaft and the second transmission wheel 6 to prevent the second transmission wheel 6 from moving back and forth on the fixed shaft. The belt is sleeved on the first transmission wheel 5 and the second transmission wheel 6, so that the double-shaft motor 4 drives the two second transmission wheels 6 to rotate synchronously. An eccentric rod 7 is provided at the edge of the end of the second transmission wheel 6 away from the cylinder body 1. The eccentric rod 7 is fixed at the edge position of the second transmission wheel 6. The eccentric rod 7 will rotate on a circumference. The eccentric rods 7 on the two second transmission wheels 6 are in a symmetrical state. From the main perspective, when the front-side eccentric rod 7 is on the right, the rear-side eccentric rod 7 is on the left. The belt drives the two second transmission wheels 6 to keep the states of the two eccentric rods 7 in a corresponding relationship. A flat ring 8 is sleeved on the outside of the eccentric rod 7. Cross bars 9 are symmetrically provided at the left and right ends of the flat ring 8. Limiting frames 10 that match the cross bars 9 are symmetrically provided on the left and right at the front and rear ends of the cylinder body 1. The four limiting frames 10 are symmetrically fixed at the front and rear ends of the cylinder body 1. Through holes that match the cross bars 9 are formed on the limiting frames 10, so that the cross bars 9 can only move left and right in the limiting frames 10. The flat ring 8 is fixed between the left and right cross bars 9. The flat ring 8 is sleeved on the outside of the eccentric rod 7. The rotation of the eccentric rod 7 can drive the flat ring 8 and the cross bars 9 to move left and right back and forth. The left and right side walls of the cylinder body 1 are respectively movably connected with a first baffle 11 and a second baffle 12 up and down in a staggered manner. A first C-shaped rod 13 is provided between the left-side first baffle 11 and the left-front cross bar 9. A second C-shaped rod 14 is provided between the right-side second baffle 12 and the right-front cross bar 9. A third C-shaped rod 15 is provided between the left-side second baffle 12 and the left-rear cross bar 9. A fourth C-shaped rod 16 is provided between the right-side first baffle 11 and the right-rear cross bar 9.Flat holes for the baffle to pass through are provided on the left and right side walls of the cylinder body 1. The baffle can move left and right on the cylinder body 1. The first baffle 11 and the second baffle 12 are arranged at intervals up and down. One corner of the baffle is fixedly connected to the U-shaped rod, and the U-shaped rod is simultaneously fixed to the cross bar 9. Thus, the left and right movement of the flat ring 8 and the cross bar 9 will drive the specific baffle to move left and right. The four U-shaped rods respectively connect and fix different cross bars 9 and baffles. The first baffle 11 on the left and the second baffle 12 on the right are connected as a whole, and the second baffle 12 on the left and the first baffle 11 on the right are connected as a whole. Cooperating with the position and rotation of the eccentric rod 7, when the first baffles 11 approach and close each other, the second baffles 12 will move away and open. Similarly, when the second baffles 12 approach and close each other, the first baffles 11 will move away and open. The opening and closing of the first baffles 11 and the second baffles 12 enable the pipe fittings in the cylinder body 1 to fall one by one and be discharged, reducing the impact on the falling pipe fittings.

[0012] Working principle: The pipe fittings are added to the device from the feed hopper 2. When adding, the first baffles 11 approach and close each other, and the second baffles 12 move away and open. The pipe fittings will be intercepted by the first baffles 11 and accumulate in the feed hopper 2. Start the double-shaft motor 4 to make the driving wheels and belts on the front and rear sides rotate synchronously. The eccentric rod 7 on the second driving wheel 6 rotates on a circumference, and the positions of the eccentric rods 7 on the front and rear second driving wheels 6 are opposite. In the front view perspective, when the front eccentric rod 7 rotates from right to left, the rear eccentric rod 7 will rotate from left to right. The front eccentric rod 7 will drive the front cross bar 9, the U-shaped rod, the first baffle 11 on the left and the second baffle 12 on the right to move together. The rear eccentric rod 7 will drive the rear cross bar 9, the U-shaped rod, the first baffle 11 on the right and the second baffle 12 on the left to move together, causing the first baffles 11 and the second baffles 12 to alternately open and close, so that the pipe fittings in the cylinder body 1 move down layer by layer between the baffles until they are discharged from the outlet plate 3, enabling the pipe fittings to fall one by one and be discharged, and reducing the impact on the falling pipe fittings.

[0013] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
