DETAILED DESCRIPTION

[0048] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0049] Example 1:

[0050] This embodiment provides a fully automatic heating, separating and blowing system for bottles, comprising:

[0051] Loading mechanism 1, used for loading preforms;

[0052] The conveying mechanism 2 is connected to one side of the feeding mechanism 1 and is used for conveying the preforms after loading;

[0053] The heating mechanism 3 is connected to the side of the conveying mechanism 2 away from the feeding mechanism 1 and is used to preheat the preforms;

[0054] The bottle blowing mechanism 4 is connected to one side of the heating mechanism 3 and is used for blow molding and shaping the bottle blank;

[0055] The grabbing mechanism is connected to the sides of the heating mechanism 3 and the bottle blowing mechanism 4, and is used to move the preforms from the heating mechanism 3 to the bottle blowing mechanism 4 and unload them after blow molding;

[0056] The heating mechanism 3 includes a U-shaped conveyor frame 30 and a heating component installed below the U-shaped conveyor frame 30;

[0057] Meanwhile, the grabbing mechanism may adopt a robot arm, and the specific structures of the robot arm and the bottle blowing mechanism 4 are both existing mature technologies, which will not be described here in detail.

[0058] It can be seen from this embodiment that by configuring the heating mechanism 3 as a U-shaped conveyor frame and a heating component placed under the U-shaped conveyor frame, the preforms are introduced into the U-shaped conveyor frame 30 for preheating after coming out of the conveyor mechanism 2, and then the preforms are grabbed by the grabbing mechanism and placed on the bottle blowing mechanism 4 after being guided out of the U-shaped conveyor frame, thereby avoiding the use of a setting such as an oven, effectively reducing the occupied area and improving space utilization.

[0059] Example 2:

[0060] This embodiment provides a fully automatic heating preform-splitting and bottle-blowing system. In addition to the technical solutions of the above embodiments, it also has the following technical features. The heating mechanism 3 also includes:

[0061] The first frame 32 is installed between the conveying mechanism 2 and the bottle blowing mechanism 4;

[0062] The driving assembly 33 is mounted on the U-shaped conveyor frame 30 and is used to drive the preform to move;

[0063] The U-shaped conveyor frame 30 includes a mounting portion 300 and a supporting portion 301 , and the mounting portion 300 is connected to the first frame 32 , the supporting portion 301 is arranged around the mounting portion 300 , and a U-shaped guide groove 34 is formed between the supporting portion 301 and the mounting portion 300 for guiding the movement of the preform.

[0064] It can be seen from this embodiment that by configuring the U-shaped conveyor frame 30 to be composed of a mounting portion 300 and a supporting portion 301, the preforms can be supported during movement, thereby improving the stability of the movement of the preforms. In addition, the U-shaped guide groove 34 formed between the mounting portion 300 and the supporting portion 301 effectively guides the movement of the preforms, thereby improving the neatness of the movement of the preforms.

[0065] Example 3:

[0066] This embodiment provides a fully automatic heating preform-splitting and bottle-blowing system. In addition to the technical solutions of the above embodiments, it also has the following technical features. The drive assembly 33 includes:

[0067] The main sprocket 330 is mounted on the mounting portion 300 and is located on the closed side of the U-shaped guide groove 34;

[0068] The secondary sprocket 331 is mounted on the mounting portion 300 and is located on the opening side of the U-shaped guide groove 34;

[0069] The chain 332 is engaged with the primary sprocket 330 and the secondary sprocket 331 and is used for transmission between the primary sprocket 330 and the secondary sprocket 331;

[0070] A pusher 35 is mounted on the chain 332 and is used to push the preform to move along the U-shaped guide groove 34;

[0071] The main sprocket 330 is connected to a driving motor 24 for driving the main sprocket 330 to rotate.

[0072] As can be seen from this embodiment, the arrangement of the primary sprocket 330 and the secondary sprocket 331 and the chain 332 sleeved on the primary sprocket 330 and the secondary sprocket 331 facilitates the driving of the pusher 35 to push the preforms along the U-shaped guide groove 34, thereby ensuring continuous preheating of the plurality of preforms and continuous production. In addition, the cyclic movement of the sprocket and the chain 332 can effectively drive the plurality of preforms to move in sequence along the U-shaped guide groove 34, thereby achieving a better guiding effect. In addition, the use of the sprocket and the chain 332 facilitates the installation of the pusher 35 on the one hand, and can effectively reduce manufacturing costs on the other hand, with a low failure rate and high reliability.

[0073] Example 4:

[0074] This embodiment provides a fully automatic heating preform-splitting and bottle-blowing system. In addition to the technical solutions of the above embodiments, it also has the following technical features. The pusher 35 includes:

[0075] The support plate 350 has one side mounted on the chain 332 and the other side extending toward the U-shaped guide groove 34 to form a pushing portion 351;

[0076] A snap-in opening 352 for inserting a bottle blank is formed between the pushing portions 351 of two adjacent support plates 350;

[0077] At the same time, the size of the bayonet 352 is between the diameter and radius of the preform;

[0078] Furthermore, specifically, the support plate 350 may be riveted to both ends of the chain links of the chain 332 to improve the connection strength and stability between the support plate 350 and the chain 332 and avoid affecting the connection between the multiple chain links.

[0079] As can be seen from the present embodiment, the pushing portion 351 formed by extending the support plate 350 toward the U-shaped guide groove 34 facilitates the abutment of the bottle blank by the pushing portion 351, thereby pushing the bottle blank to move along the U-shaped guide groove 34, ensuring the sequential pushing of multiple bottle blanks and improving the conveying stability. In addition, a bayonet 352 for the bottle blank to be clamped is formed between two adjacent support plates 350, and the size of the bayonet 352 is between the diameter and radius of the bottle blank, which can effectively improve the stability of the bottle blank when moving along the U-shaped guide groove 34.

[0080] Example 5:

[0081] This embodiment provides a fully automatic heating preform-splitting and bottle-blowing system. In addition to the technical solutions of the above embodiments, it also has the following technical features. The pusher 35 also includes:

[0082] The rotating shaft 353 is mounted on the pushing portion 351;

[0083] Bearing 354, sleeved on the rotating shaft 353;

[0084] The friction-increasing strip 355 is mounted on the support portion 301 and is disposed corresponding to the bearing 354 and is used to promote the rolling of the preform along the U-shaped guide groove 34;

[0085] The shaft 353 and the pushing portion 351 may be welded, the inner diameter of the bearing 354 and the shaft 353 may be interference fit, and the friction strip 355 may be made of rubber or aluminum alloy with friction grooves on the surface of the aluminum alloy.

[0086] It can be seen from this embodiment that, by means of the friction-increasing strip 355 and the corresponding bearing 354, when the bottle blank is pushed to move along the U-shaped guide groove 34, one side is pushed by the bearing 354 and the other side abuts against the friction-increasing strip 355, thereby increasing friction and causing the bottle blank to roll forward, that is, the bottle blank is caused to rotate while moving along the U-shaped guide groove 34, thereby effectively improving the uniformity of preheating the bottle blank by the heating assembly, and the structure is simple, and no additional rotation device is required to drive the bottle blank to rotate, thereby effectively reducing the manufacturing cost.

[0087] Example 6:

[0088] This embodiment provides a fully automatic heating preform separation and bottle blowing system. In addition to the technical solutions of the above embodiments, it also has the following technical features. The heating component includes:

[0089] The heating tube assembly 31 is installed in the first frame 32 and is located below the U-shaped conveyor frame 30 and is arranged along both sides of the U-shaped guide groove 34;

[0090] An induced draft fan is installed in the first frame 32 and is used to guide the hot air from the heating tube group 31 downward;

[0091] The heating tube assembly 31 is a mature existing technology, and its specific structure is not described here any more.

[0092] As can be seen from this embodiment, by placing the heating tube group 31 below the U-shaped conveyor frame and arranging it along both sides of the U-shaped guide groove, it is convenient to preheat the part of the bottle preform to be blow-molded, and the draft fan is convenient to lead the hot air downward, preventing the hot air generated by the heating tube group 31 from moving upward, preheating the bottle mouth of the bottle preform, preventing the bottle mouth of the bottle preform from being deformed during subsequent grasping, and effectively ensuring the production quality of the product.

[0097] Among them, the conveyor belt 11 is provided with a driving device for driving its circular movement, and a baffle is provided on the conveyor belt 11 to prevent the bottle preforms from falling when conveying the bottle preforms obliquely upward. The specific structure of the driving device is an existing mature technology and will not be repeated here.

[0098] It can be seen from this embodiment that the convenience of loading is improved by adopting a conveyor rack to convey the bottle blanks obliquely upward into the conveying mechanism 2, and the setting of the material frame 10 and the extension of the conveyor rack into the material frame 10 allow the processed bottle blanks to be directly poured into the material frame 10, further improving the convenience.

[0103] The correction component includes two rotating rollers 23 arranged side by side and tilted, and a driving motor 24 for driving the two rotating rollers 23 to rotate. The correction component is used to align the axial direction of the bottle blank with the conveying direction.

[0104] As can be seen from this embodiment, by arranging a correction component in the conveying mechanism 2, the angle of the bottle preform can be adjusted after the bottle preform is conveyed by the conveyor belt 11, so that its axis is parallel to the conveying direction, and then after the bottle preform enters the linear conveying frame 21, it can be supported by the linear conveying frame 21, thereby improving the stability and accuracy of the bottle preform conveying, and the correction component adopts two rotating rollers 23 arranged side by side, which can effectively adjust the angle of the bottle preform, so that the axis of the bottle preform is parallel to the axes of the two rotating rollers 23, thereby ensuring the correction of the position of the bottle preform; and the rotating rollers 23 and the linear conveying frame 21 are both inclined, so that the bottle preform can automatically slide down due to gravity, avoiding the need for an additional power drive, and having a simple structure, energy saving effect, and effectively reducing manufacturing costs.
