Description

Technical Field

[0001] The invention belongs to the technical field of conveying devices, and in particular relates to a raw material conveying device for a bottle blowing machine. Background Art

[0002] The bottle blowing machine is a molding equipment used to manufacture hollow plastic products, especially suitable for producing various types of bottles, containers and other hollow products. The specific working principle is that the plastic particles are first formed into a tubular preform by an injection molding machine or an extruder. Then the preform is placed in the mold of the bottle blowing machine and heated to an appropriate temperature by infrared or other means to soften the plastic but not melt it. Next, compressed air is injected into the preform to expand it and cling to the inner wall of the mold to form the desired bottle shape. Finally, the air source is turned off and the bottle is allowed to cool naturally or forcefully in the mold to ensure that it is completely hardened before the finished product is taken out. The raw material conveying device for the bottle blowing machine generally refers to conveying the tubular preform made by the injection molding machine or the extruder to the mold of the bottle blowing machine for blow molding. The conveying equipment in the prior art generally uses a conveyor belt for conveying, which only has the function of conveying and requires manual placement of the workpiece, which is inconvenient to use and has low conveying efficiency.

[0003] The existing Chinese patent document with publication number CN213678711U proposes a bearing steel billet conveying device, which improves the efficiency of conveying billets by advancing the billets after punching and cutting through the feed slide into the baffle, and conveying the billets through a chain. After the billets are delivered to the right place, the billets are pushed out by a pushing mechanism to realize automatic unloading, but the tubular preforms made by the injection molding machine are prone to tipping over during the pushing process in the absence of a limiting structure, and are prone to misalignment when subsequently entering the bottle blowing machine, resulting in quality problems in the finished product.

[0004] Therefore, the present invention proposes a raw material conveying device for a bottle blowing machine, which solves the problem that the conveying equipment in the prior art is prone to tipping over during the pushing process of the tubular preforms in the absence of a limiting structure, and is prone to dislocation when subsequently entering the bottle blowing machine.

[0033] Embodiment 1

A rotating disk 23 is fixedly installed above the driving gear 22, and a card slot adapted to the limit cover 25 is provided on the outer side of the rotating disk 23. A pulley 241 is provided on the side surface of the preform conveying seat 24, and a spring push rod 242 is fixedly installed on the upper surface of the preform conveying seat 24. The upper end of the spring push rod 242 is fixedly connected to the lower surface of the limit ring 27, and the inner surface of the limit ring 27 is fixedly connected to the lower surface of the limit ring 27. An air inlet pipe 26 is fixedly installed on the preform conveying seat 24, a slide groove adapted to the air inlet pipe 26 is arranged inside the preform conveying seat 24, an air inlet sealing ring 261 is fixedly installed on the lower end of the air inlet pipe 26, an air source pipe extrusion gasket 262 is slidably installed below the air inlet sealing ring 261, an air source pipe extrusion gasket 262 is movably installed inside the air inlet sealing ring 261, a first sealing ring 263 is movably installed inside the air source pipe extrusion gasket 262, and the upper end of the first sealing ring 263 is fixedly connected to the lower end of the air inlet pipe 26;

[0035] In this embodiment, the conveyor frame 1 plays the role of fixing the conveying limit guide rail 2, the bottle blowing machine installation area protection frame 11 is used to limit the installation position of the bottle blowing machine, the inner side of the bottle blowing machine installation area protection frame 11 can be used for the mold assembly of the bottle blowing machine, and the air source assembly of the bottle blowing machine can be installed below the air source pipe inlet 13 of the bottle blowing machine. The injection molding extruder installation area protection frame 12 is used to limit the installation position of the injection molding machine, and the extrusion component of the injection molding machine is fixed above the injection molding extruder installation area protection frame 12, so that the tubular preform extruded by the injection molding machine enters the limit cover 25 through the notch above the air source pipe inlet 13 of the bottle blowing machine. The limiting ring 27 of the upper part limits the tubular preform. At this time, the upper end of the air inlet pipe 26 is inserted into the lower part of the inner part of the tubular preform. The motor drives the driving gear 22 to rotate and drive the conveying chain 21 to rotate. The limiting strip on the outer side of the conveying chain 21 pushes the lower part of the air inlet pipe 26 to drive the preform conveying seat 24 to move and convey as a whole. The pulley 241 rolls over the conveying limiting guide rail 2 to make the preform conveying seat 24 move more smoothly. The rotating disk 23 rotates synchronously with the driving gear 22, and the card slot of the rotating disk 23 is inserted into the outer side of the limiting cover 25, driving the preform conveying seat 24 to reverse as a whole and enter the bottle blowing machine installation The preform conveying seat 24, the limiting cover 25 and the limiting ring 27 ensure the smooth transition of the tubular preform from the injection molding machine to the blow molding machine mold, avoiding possible damage or deformation during transportation. The spring push rod 242 makes the limiting ring 27 rise and fall inside the limiting cover 25. When the preform conveying seat 24 moves to make the tubular preform reach the inner side of the blow molding machine mold, the blow molding machine mold is closed. While closing the mold, the limiting ring 27 descends to cancel the limiting fixation of the tubular preform. At the same time, the air inlet pipe 26 moves down to connect and engage with the air pipe of the air source assembly. When closing, the air inlet pipe 26 is sleeved on the outside of the air pipe, the air inlet sealing ring 261 is squeezed by the outside of the air pipe, and the air source pipe extrusion gasket 262 is squeezed inward to produce compression deformation, so that the first sealing ring 263 wraps the clamping point between the air pipe and the air inlet sealing ring 261, thereby increasing the sealing performance and facilitating the air intake into the tubular preform inside the mold for blow molding, quickly and accurately completing the mold closing and blow molding operations, thereby improving the flexibility and response speed of production, and the close fit and limit fixing design between the various components provide a stable operating environment, so that the tubular preform can be smoothly transported, thereby improving production quality and efficiency.

[0036] Embodiment 2

[0037] See also Figures 1 to 13On the basis of the first embodiment, the present embodiment further proposes that a toggle slider 271 is fixedly installed on the outer surface of the limiting ring 27, a slide groove adapted to the toggle slider 271 is provided on the side wall of the limiting cover 25, a spring locking buckle 2711 is movably installed on the inner side of the toggle slider 271, a locking block 251 adapted to the toggle slider 271 is fixedly installed on the outer wall of the limiting cover 25, an upper fixing groove 2511 is provided above the locking block 251, a lower fixing groove 2512 is provided below the locking block 251, and a locking groove 252 is provided above the inner wall of the limiting cover 25;

[0038] In this embodiment, the limiting ring 27 slides within the limiting cover 25 and the locking block 251 by toggling the slider 271. When the spring locking buckle 2711 is stuck in the upper fixing groove 2511, the limiting ring 27 is in a limiting state for the tubular preform, ensuring that the tubular preform is stably fixed before entering the mold to prevent it from being offset or deformed during transportation or preparation. When the spring locking buckle 2711 is stuck in the lower fixing groove 2512, the limiting ring 27 is in a stripping state, which is convenient for the tubular preform to be clamped by the mold, and the air inlet pipe 26 is driven to engage with the air inlet pipe of the air source assembly to blow mold the tubular preform, ensuring that the preform can smoothly detach from the limiting device before the mold is closed, avoiding unnecessary interference. The movable mechanism of the limiting ring 27 and the air inlet pipe 26 inside the limiting cover 25 can make the tubular preform firmly fixed before entering the mold of the bottle blowing machine, ensuring the consistency of its shape and size, and reducing the scrap rate caused by instability.

[0039] Embodiment 3

[0040] See also Figures 1 to 13 On the basis of the second embodiment, the present embodiment further proposes that an inner retaining ring 272 is fixedly installed above the inner surface of the toggle slider 271, a preformed part limiting frame 273 is slidably installed on the side wall of the limiting ring 27, a wedge block 2731 is fixedly installed on the outer side of the preformed part limiting frame 273, an extrusion spring 2732 is fixedly installed above the preformed part limiting frame 273, one end of the extrusion spring 2732 is fixedly connected to the surface of the inner retaining ring 272, arc limiting strips 2733 are movably installed on both sides of the preformed part limiting frame 273, a clamping frame 2734 is fixedly installed on the inner side of the preformed part limiting frame 273 through a spring, and a card slot adapted to the clamping frame 2734 is provided on the inner wall of the arc limiting strip 2733;

[0041] In this embodiment, as the limiting ring 27 extends to limit the tubular preform, the wedge block 2731 is gathered by the locking groove 252. At this time, the extrusion spring 2732 is in a compressed state. At this time, the preform limiting frame 273 slides inward, and the arc limiting strip 2733 fits and limits the surface of the tubular preform, ensuring that the preform is stably fixed before entering the mold to prevent it from deflecting or deforming during transportation or preparation. The clamping frame 2734 is made of silicone and clamps and fixes the tubular preform under the action of the spring, which can be done without damaging the surface of the preform. In this way, a stable clamping force is provided to prevent the preform from tilting or sliding during the transportation process, and the action of the spring allows the clamping force of the clamping frame 2734 to be fine-tuned according to the different specifications of the preforms, ensuring that appropriate clamping force can be provided for preforms of various sizes and shapes, thereby enhancing the versatility and flexibility of the equipment. When the limiting ring 27 moves downward for peeling, the extrusion spring 2732 naturally expands on the inside of the toggle slider 271, causing the preform limiting frame 273 to retreat, naturally canceling the clamping and limiting of the preforms, reducing manual intervention and improving production efficiency.

[0042] Embodiment 4

[0043] See also Figures 1 to 13 On the basis of the third embodiment, the present embodiment further proposes that a cutting knife holder 32 is fixedly installed above the automatic shearing mounting frame 3 in the injection molding area, a preform introduction tube 31 is fixedly installed above the cutting knife holder 32, a sliding positioning introduction block 311 is symmetrically fixedly installed inside the preform introduction tube 31, a cutting support pad 321 is fixedly installed on one side of the cutting knife holder 32, a cutting knife 322 is arranged on the other side of the cutting knife holder 32, a telescopic rod 1 323 for driving the cutting knife 322 to move is fixedly installed on the outer side of the cutting knife holder 32, a telescopic rod 2 33 is fixedly installed below the automatic shearing mounting frame 3 in the injection molding area, a lifting and toggling block 34 is fixedly installed at one end of the telescopic rod 2 33, and the lifting and toggling block 34 is a clamp-shaped clamp, a telescopic rod 3 41 is fixedly installed on the inner side of the automatic stripping mounting frame 4 in the blowing bottle area, a pressing and toggling block 42 is fixedly installed at one end of the telescopic rod 3 41, and the size and shape of the pressing and toggling block 42 are the same as those of the lifting and toggling block 34;

[0044] In this embodiment, when the preform conveying seat 24 moves to the lower part of the injection molding extruder discharge port, the tubular extrusion enters the preform introduction tube 31, and the sliding positioning introduction block 311 is designed with a movable ball inside, so that the tubular extrusion is correctly introduced into the cutting knife holder 32. At this time, the telescopic rod 1 323 pushes the cutting knife 322 to move toward the cutting support pad 321 to cut the tubular extrusion into a tubular preform, and enters the limiting cover 25 and the air inlet pipe 26. At this time, the telescopic rod 23 drives the lifting and toggling block 34 to lift and toggle the toggle slider 271 to rise and make it snap into the upper At the fixed groove 2511, the tubular preform is limited and then conveyed. When the preform conveying seat 24 conveys the preform to the mold of the bottle blowing machine on the protective frame 12 of the injection extruder installation area, the telescopic rod three 41 drives the downward pressing toggle block 42 to pull the toggle slider 271 downward to make it fit into the lower fixed groove 2512. At this time, the limiting ring 27 is naturally peeled off, which is convenient for the mold to clamp the preform. The entire process from extrusion, cutting, limiting to final blow molding is highly automated and continuous, reducing manual intervention and significantly improving production efficiency.

[0045] Embodiment 5

[0046] See also Figures 1 to 13 Based on the fourth embodiment, this embodiment further proposes a conveying method of a raw material conveying device for a bottle blowing machine, comprising the following steps:

[0047] Step 1: The motor drives the driving gear 22 to rotate and drive the conveying chain 21 to rotate. The limit bar on the outer side of the conveying chain 21 pushes the lower side of the air inlet pipe 26 to drive the preform conveying seat 24 to move and convey as a whole. The pulley 241 rolls above the conveying limit guide rail 2 to make the preform conveying seat 24 move more smoothly. The rotating disk 23 rotates synchronously with the driving gear 22.

[0048] Step 2: When the preform conveying seat 24 moves to the lower side of the injection molding extruder discharge port, the tubular extrusion enters the preform introduction tube 31 and is correctly introduced into the cutting knife holder 32. The telescopic rod 1 323 pushes the cutting knife 322 to move toward the cutting support pad 321 to cut the tubular extrusion into a tubular preform, and enters the limiting cover 25 and the air inlet pipe 26.

While closing the mold, the limiting ring 27 descends to cancel the limiting fixation of the tubular preform. At the same time, the air inlet pipe 26 moves down and is connected and engaged with the air pipe of the air source assembly, and the air is blown into the tubular preform inside the mold;

[0050] Step 4: After the blow molding is finalized, the mold is unfolded and the formed bottles are transported out of the protective frame 11 area of ​​the blow molding machine installation area.
