Description

Technical Field

[0001] The present invention relates to the technical field of bottle blowing machines, in particular to a variable-distance transfer connection mechanism between a bottle blowing machine and a filling machine with a linear blowing, filling and rotating mechanism. Background Art

[0002] A blow molding machine is a device that produces hollow plastic containers. The process consists of extracting the preform, inserting the preform into the mold, closing the mold, and stretch-blow molding. The speed of each step directly affects the overall efficiency and cycle time of the bottle. After the preform is processed, the ejector mechanism pushes the preform out of the blow molding machine, allowing it to be collected for subsequent packaging or branding.

[0003] Currently, the traditional transmission method from the bottle discharge section of the blow molding machine to the filling machine mostly uses an air conveyor, which has the disadvantages of large floor space, high energy consumption, easy bottle jamming and poor air conveying. Alternatively, bottles are hung individually on the conveyor belt, resulting in slow and inefficient bottle discharge. There is no structure to catch multiple finished products on the conveyor belt, making efficient bottle discharge inconvenient. Furthermore, there is a very small chance that bottles blown by the blow molding machine will break. Once the broken bottles are transported to the filling machine for filling, the beverage will leak. Therefore, they need to be removed before entering the filling machine. Summary of the Invention

Therefore, the detailed description of the specific internal parts is not expanded in this invention. When the bottom of the bottle insert core assembly 32 is inserted into the bottle mouth of the bottle body, it is in a state of clearance fit, which facilitates removal.

[0023] In the present invention, a row of bottles blown into shape in the bottle blowing machine is taken out by clamping the first clamping claws 214 of the entire row of bottles at the neck by controlling the movement of the first clamping claw bracket 213, and then sent to the position of the positioning plate 38. After the first inserting plate 207 is extended into place, the first inserting plate 207 and the positioning plate 38 are respectively inserted into the front and rear sides of the groove of the bottle neck, so that the necks of the entire row of bottles are fixed and will not fall off, but can move freely left and right, such as Figure 7 Then the pressing mechanism 37 controls the pressing plate 373 to press down, so that the bottom of the corresponding bottle inserting core assembly 32 directly below it is inserted into the bottle mouth clamped by the first clamping jaw 214, and the first clamping jaw 214 withdraws. Under the drive of the variable pitch screw 33, the entire row of bottles moves to the left, and after the pitch is changed, it reaches the pulling mechanism 36. The hook at the end of the lever 362 lifts the bottle inserting core assembly 32 below upward, and the bottom of the bottle inserting core assembly 32 is separated from the bottle mouth. At this time, the bottle is clamped by the first arc-shaped notch 421 on the turntable 42 and continues to move forward along the gap between it and the first arc-shaped guide plate 43. The groove on the neck of the bottle is clamped between the first arc-shaped notch 421 and the first arc-shaped guide plate 43 until the bottle is transported to the bottle. The bottle is sent to the arc-shaped notch at the front end of the gripping plate 54. When the vertical rod 56 enters the first groove 571, the claw 55 is acted upon by the spring force to hold the bottle neck inward and cooperate with the gripping plate 54 to clamp the bottle body, so that the bottle smoothly enters the bottle conveying and rejection mechanism 5. The bottle continues to move forward driven by the rotating disc 53. When a broken bottle is detected, the cylinder rod of the third cylinder 59 is activated to extend and push the front end of the arc-shaped long block 57 to deform outward, driving the vertical rod 56 there to overcome the spring force and move so that the claw 55 opens to ensure that the bottle falls, thereby completing the rejection of the broken bottle. This detection can be set in the bottle conveying and rejection mechanism 5, or in the bottle distance changing mechanism 3, or in the bottle taking out mechanism 4. If the bottle is normal, the third cylinder 59 will not be activated, and the bottle will be transported to the second groove 572 of the arc-shaped long block 57. At this exit position, the vertical rod 56 enters the second groove 572, causing the claw 55 to open relative to the gripping plate 54 to release the bottle body. At this time, the groove on the bottle neck has entered the second arc-shaped notch 611 and the second arc-shaped guide plate 62, and the bottle is finally sent to the bottle receiving mechanism 6 of the filling machine for filling.

[0024] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the invention. Any simple modification, equivalent change or modification made to the above embodiment based on the technical principle of the present invention still falls within the scope of the technical solution of the present invention.
