[0022] In this embodiment, Figure 1 , Figure 4 and Figure 5 As shown, the feed assembly 2 includes two mounting plates 201 fixedly connected to the top of the body 1, a feed hopper 202 is fixedly connected between the tops of the two mounting plates 201, a motor 203 is fixedly connected to one side of the feed hopper 202, a gear 204 is fixedly connected to the output end of the motor 203, a gear ring 205 is meshed on one side of the gear 204, two movable rods 206 penetrate the two sides of the gear ring 205, two springs 207 are fixedly connected to the bottom surface of the gear ring 205, an annular plate 208 is fixedly connected between the bottom ends of the two springs 207, two connecting rods 209 are fixedly connected to the top of the annular plate 208 near the inner ring, and a toggle rod 2010 is fixedly connected between the top ends of the two connecting rods 209.

[0023] In this embodiment, Figure 5As shown, the inner diameter of the annular plate 208 is smaller than the bottom outlet diameter of the feed hopper 202, and the difference between the annular plate 208 and the feed hopper 202 is fixedly connected with two connecting rods 209, and the toggle rod 2010 connected between the top ends of the two connecting rods 209 is a cross-shaped structure; the toggle rod 2010 with the cross-shaped structure has a better dredging effect on the feed hopper 202, and the two connecting rods 209 are attached to the inner wall of the outlet of the feed hopper 202, which minimizes the obstruction of the connecting rods 209 to the discharge of materials.

[0024] In this embodiment, Figure 1 , Figure 4 and Figure 5 As shown, the inner ring of the gear ring 205 is rotatably connected to the outer side of the bottom of the feed hopper 202, and two holes are provided on both sides of the gear ring 205, in which movable rods 206 are slidably connected, and an elastic structure is formed between the gear ring 205 and the annular plate 208 through the spring 207; the elastic structure can make the annular plate 208 descend and the spring 207 stretch through the toggle rod 2010 when the raw materials in the feed hopper 202 fall, and the spring 207 will rebound, so that the annular plate 208 drives the toggle rod 2010 to vibrate up and down while rotating, and the anti-blocking effect is better.

[0025] In this embodiment, Figure 2 and Figure 3 As shown, the buffer assembly 3 includes a protective shell 301 fixedly connected to the bottom of the body 1, and two mounting grooves 302 are provided on the inner walls on both sides of the protective shell 301. The insides of the two mounting grooves 302 are rotatably connected with a first connecting shaft 303, and the end of the first connecting shaft 303 away from the mounting groove 302 is fixedly connected with a buffer plate 304, and the left side of the buffer plate 304 is fixedly connected with a torsion spring 305. The inner wall of the protective shell 301 is rotatably connected with a second connecting shaft 306, and the middle part of the second connecting shaft 306 is fixedly connected with a discharge plate 307, and the second connecting shaft 306 passes through the middle part of the ratchet 308, and the top of the ratchet 308 is fitted with a pawl 309.

[0026] In this embodiment, Figure 2 and Figure 3 As shown, the right end of the second connecting shaft 306 extends from the inside of the protective shell 301 to the outside and is fixedly connected to the ratchet 308, and the pawl 309 is rotatably connected to the right side of the protective shell 301 through a rotating shaft; this structure can adjust the inclination angle of the discharge plate 307 so as to change the opening size between the discharge plate 307 and the protective shell 301 according to plastic bottles of different sizes.

[0028] The use method and advantages of the utility model: When the blow molding machine with a buffer structure is used, the working process is as follows:

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, first, the raw materials are conveyed into the machine body 1 through the feed hopper 202. When the raw materials are conveyed slowly or blocked, the motor 203 is started to drive the gear 204 to rotate. The rotation of the gear 204 will drive the gear ring 205 meshing therewith to rotate. The gear ring 205 will drive the annular plate 208 at the bottom to rotate through two movable rods 206. When the annular plate 208 rotates, it will rotate through the connecting rod 209 with the toggle rod 2010 at the top to stir and break up the raw materials in the feed hopper 202 to avoid the raw materials being blocked in the feed hopper 202 and affecting the feeding speed. No manual cleaning is required. When the plastic bottles are produced, they will fall from the feeding pipe 4. At this time, the plastic bottles will fall on the buffer plate 304. Because the buffer plate 304 The first connecting shaft 303 is used for rotation, and the central axis of the first connecting shaft 303 is located behind the central axis of the discharge tube 4. Therefore, the plastic bottle will not fall in the middle of the buffer plate 304, but in a relatively forward position, so that the buffer plate 304 rotates around the first connecting shaft 303, and at the same time drives the torsion spring 305 to deform. Then the buffer plate 304 tilts to discharge the plastic bottles on the top to slide onto the discharge plate 307 to complete the unloading, and the buffer plate 304 will reset under the action of the torsion spring 305. The buffer plate 304 is used to buffer the finished plastic bottles, thereby reducing the noise when the plastic bottles fall, and at the same time reducing the height difference of the plastic bottles falling, thereby reducing the probability of damage to the plastic bottles.
