Description

Technical Field

[0001] The utility model belongs to the technical field of bottle blowing machines, in particular to a preform washing device before preform feeding of a bottle blowing machine. Background Art

[0002] After the preforms are produced by the injection molding machine, they need to be transported to the bottle blowing machine for processing before they can become products. During the transportation process, they are inevitably stained with dust, paper scraps, hair and other items, so the surface of the preforms needs to be cleaned. However, due to the huge number of preforms, manual inspection is time-consuming and easy to miss. In the past, the bottle blowing machine used an electrostatic dust removal device to remove dust or small paper scraps in the preforms, but it would be impossible to clean them up if it encountered longer hair and larger paper scraps. Therefore, it is urgent to study a preform washing device before the bottle blowing machine enters the preform to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

Solenoid valve; the water circuit solenoid valve also uses PWM pulse width flushing mode, repeatedly spraying several times within one second to achieve a quick cleaning effect; the lower part of the air-water distributor 1 is vertically connected with a rotating drive component 3; the upper part of the air-water distributor 1 is bolted to a horizontally arranged supporting plate 4; a plurality of electric rotating clamps 2 are evenly bolted to the edge of the supporting plate 4; the circumferential outer wall of the air-water distributor 1 is vertically connected with a lifting drive component 5; a plurality of nozzles 6 corresponding to the electric rotating clamps 2 are evenly connected to the lifting drive component 5 in a circular direction; a plurality of nozzles 6 are connected to the air-water distributor 1; the nozzle 6 is an L-shaped structure; the outlet end of the nozzle 6 is arranged at the upper end of its vertical end; the outlet end of the nozzle 6 vertically points to the corresponding electric rotating clamp 2. When in use, before the preform is fed into the bottle blowing machine, the air-water distributor 1 is driven to rotate intermittently by the rotary drive component 3, and at the same time, any electric rotary clamp 2 clamps the bottle preform after reaching the preform grabbing position, and then the air-water distributor 1 drives the electric rotary clamp 2 to rotate horizontally through the carrying plate 4. After the electric rotary clamp 2 reaches the set position, the clamped bottle preform is flipped, so that the bottle mouth of the clamped bottle preform is vertically downward. At this time, the nozzle 6 corresponding to the bottle preform facing the bottle mouth on the lifting drive component 5 first sprays water to the bottle mouth and then sprays air to the bottle mouth, thereby realizing efficient cleaning of the bottle preform, and then the electric rotary clamp 2 flips the cleaned bottle preform to the bottle mouth facing vertically upward, and drives the electric rotary clamp 2 to rotate to the preform placing position on the carrying plate 4. Finally, the electric rotary clamp 2 releases the clamp to release the cleaned bottle preform, thereby completing the cleaning work of a bottle preform, which not only effectively improves the cleaning efficiency and effect of the bottle preform, but also can remove dust, paper scraps, hair and other objects attached to the surface of the bottle preform, and also effectively ensures the processing efficiency of the bottle preform.

[0024] Among them Figure 2-3As shown, the rotary drive assembly 3 includes a vertically fixed support cylinder 301; the support cylinder 301 is bolted to the bracket of the bottle blowing machine; the lower end of the support cylinder 301 is bolted to a vertically arranged servo motor 302; the servo motor 302 has an encoder; the output shaft of the servo motor 302 is coaxially fixed with a transmission shaft 303 through a conventional coupling in the art; the upper end of the transmission shaft 303 penetrates into the support cylinder 301 and is bolted to the lower part of the air-water distributor 1; the transmission shaft 303 is in clearance fit with the support cylinder 301. When in use, the air-water distributor 1 is driven to rotate by the servo motor 302 through the transmission shaft 303, and the encoder of the servo motor 302 is used to record the rotation angle position. When the air-water distributor 1 drives the electric rotating jaw 2 to rotate to the specified position through the carrier plate 4, the electric rotating jaw 2 flips the clamped bottle preform, thereby ensuring that the state of the bottle preform corresponds to the working mode of the nozzle 6, effectively ensuring the cleaning efficiency of the bottle preform.

During use, since the cylindrical cam 501 is always in a stationary state, the roller 505 rolls on the working surface of the cylindrical cam 501 when the air-water distributor 1 drives the guide rail 502 to rotate, so that the nozzle 6 is moved away from or close to the clamped bottle preform, effectively ensuring the cleaning effect of the bottle preform, while also avoiding problems such as interference between the bottle preform and the nozzle 6; and when the roller 505 is at the wave crest 5011, the bottle mouth of the clamped bottle preform is vertically downward, and when the roller 505 is at the wave trough 5012, the bottle mouth of the clamped bottle preform is vertically upward.

[0027] Among them Figure 5-6As shown, the inlet end of the nozzle 6 is connected to the adapter block 7; the adapter block 7 is screwed to a surface of the slider 503; the adapter block 7 is connected to the delivery pipe 8; the end of the delivery pipe 8 away from the adapter block 7 is connected to the air-water distributor 1. When in use, the air-water distributor 1 delivers air or water to the nozzle 6 through the delivery pipe 8 and the adapter block 7, so that the nozzle 6 sprays air or water into the preform, effectively ensuring the working efficiency of the nozzle 6.
