[0002] PE extrusion blow bottle is made of polyethylene as raw material. After high temperature heating, the raw material is extruded or injection molded to obtain a tubular plastic preform. While hot (or heated to a softened state), it is placed in a split mold. After the mold is closed, compressed air is immediately introduced into the preform to inflate the plastic preform and make it adhere tightly to the inner wall of the mold. After cooling and demolding, various hollow products are obtained.

[0003] During the production process, there will be residual material at the bottle mouth, which needs to be removed manually in the later stage. The workload is large, and the manual removal has low cutting accuracy, which affects the production efficiency and quality of the product. Summary of the Invention

The first connecting seat slides, driving the two clamping blocks to be located on both sides of the product. The two clamping blocks clamp the product. The first connecting seat slides so that the residual material is aligned with the cutting knife. The cutting knife slides to cut off the residual material at the bottle mouth, thereby improving the production efficiency of the device.

[0007] Preferably, the blow molding mechanism includes a forming mold base and a blow needle. The forming mold base is slidably connected to the first connecting seat, and the sliding direction of the forming mold base is perpendicular to the sliding direction of the first connecting seat. The forming mold base is provided with two, and concave forming cavities are provided on the opposite surfaces of the two forming mold bases.

[0048] The operating principle of a PE bottle blowing production device according to an embodiment of the present application is as follows: the extrusion mechanism 2 operates to form the raw material into a single parison, the piston rod of the first drive cylinder 35 contracts, driving the two first mounting frames 34 closer together, causing the molding cavities 411 of the two molding die holders 41 to close, so that the parison is embedded in the molding cavity 411. The first drive motor 331 operates to drive the first screw rod 332 to rotate, the first screw rod 332 is threadedly connected to the first connecting seat 32, and the first connecting seat 32 slides. When the two molding cavities 411 are located below the two blow needles 42, the piston rod of the blow molding drive cylinder 44 extends, driving the second connecting seat 43 downward, driving the blow needle 42 to extend into the two parisons, and the external air source operates to cause the parison to expand and press against the wall of the molding cavity 411 to form a product.

[0049] The piston rod of the first drive cylinder 35 extends, driving the two first mounting frames 34 away from each other, so that the outer wall of the product is separated from the wall of the molding cavity 411. The first connecting seat 32 slides, so that the two clamping blocks 39 are located below the two blow needles 42. The piston rod of the first drive cylinder 35 contracts, driving the two first mounting frames 34 to move closer to each other, so that the molding cavities 411 of the two molding mold seats 41 are molded together, so that the preform is embedded in the molding cavity 411, and the product is embedded in the clamping groove 391. The piston rod of the blow molding drive cylinder 44 contracts, driving the second connecting seat 43 to move upward, driving the blow needle 42 to separate from the two products. The piston rod of the vertical drive cylinder 38 contracts, driving the third mounting frame 37 to move downward, driving the clamping block 39 to move downward, and driving the product to move downward. The first connecting seat 32 slides, causing the limiting rod 16 to engage with the embedded groove 392. The clamping block 39 is positioned below the cutting blade 64. The piston rod of the vertical drive cylinder 38 extends, driving the third mounting bracket 37 upward, driving the clamping block 39 upward, and driving the product upward, so that the residual material is positioned between the two cutting blades 64. The upper end of the abutment block 310 abuts the cutting blade 64, pushing the abutment block 310 downward. The abutment block 310 abuts the chamfer 3112, pushing the abutment block 311 to overcome the elastic force of the reset member 312 and slide, driving the buffer block 313 to abut the outer wall of the product. The piston rod of the cutting drive cylinder 65 retracts, driving the two mounting portions 641 toward each other, and the two abutment portions 642 abut the outer wall of the residual material. The piston rod of the feeding drive cylinder 62 extends, driving the third connecting seat 61 to slide away from the column 12, driving the cutting blade 64 to slide, driving the residual material to slide, driving the driving gear 665 to slide, and the driving gear 665 engages with the driving rack 666. The driving gear 665 rotates, driving the active bevel gear 663 to rotate, the active bevel gear 663 engages with the driven bevel gear 664, and the driven bevel gear 664 rotates, driving the driving screw 662 to rotate. The driving screw 662 is threadedly connected to the connecting block 6611, driving the scraper 661 to slide, so that the residual material is separated from the cutting blade 64. The piston rod of the cutting drive cylinder 65 extends, driving the two cutting blades 64 away from each other, and the residual material falls into the receiving trough 631.

[0050] The piston rod of the vertical drive cylinder 38 retracts, driving the third mounting bracket 37 downward, which in turn drives the clamping block 39 downward, and the product downward. The piston rod of the first drive cylinder 35 extends, driving the two first mounting brackets 34 away from each other, separating the outer wall of the product from the wall of the clamping groove 391, and the product falls onto the support block 151. The piston rod of the feed drive cylinder 62 retracts, driving the third connecting seat 61 to slide closer to the column, driving the cutting blade 64 to slide above the clamping block 39.

[0051] The first connecting seat 32 slides, and after the clamping block 39 clamps the next group of products, the clamping block 39 abuts against the products, and slides the products along the supporting block 151 into the storage box 5.
