Description

Technical Field

[0001] The invention belongs to the technical field of plastic processing, and specifically relates to taking out a blown part from a model, and in particular to a demoulding mechanism and a demoulding method of a packaging bottle injection-blowing machine. Background Art

[0002] A packaging bottle is a type of packaging container in the packaging industry, generally referring to a container with a narrower mouth than the abdomen and a longer neck.

[0003] For packaging bottles made of plastic materials, the process of producing packaging bottles by injection blow molding machine needs to go through injection molding, blow molding and demoulding. In order to improve work efficiency, multi-station injection blow molding machine is often used.

[0004] During the demoulding process of the packaging bottle, the multi-station turntable drives the formed packaging bottle to rotate to the demoulding mechanism, and the packaging bottle is horizontally placed on the demoulding mechanism. The demoulding mechanism moves horizontally relative to the multi-station turntable to realize the packaging bottle being separated from the multi-station turntable.

[0005] However, when the packaging bottle is in contact with the demoulding mechanism, the packaging bottle and the demoulding structure are clamped tightly, which will result in the packaging bottle being unable to be separated from the demoulding mechanism after it is separated from the multi-station turntable; and when the packaging bottle and the demoulding structure are clamped loosely, the packaging bottle cannot maintain a horizontal state.

[0006] Therefore, how to solve the problem of the packaging bottle being too tight or too loosely connected with the demoulding mechanism, which makes it difficult to disengage or unable to maintain a horizontal state, is a technical problem that urgently needs to be solved in the field.

[0007] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

[0067] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0068] In this article, when it is mentioned that the first component is located on the second component, this may mean that the first component may be directly formed on the second component, or the third component may be interposed between the first component and the second component. In addition, in the drawings, in order to effectively describe the technical content, the thickness of the components may be exaggerated or reduced.

[0069] Herein, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as "at least one of..." modify the entire list of elements when following a list of elements, rather than modifying individual elements in the list. For example, the expression "at least one of a, b, and c" should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0070] The terms used herein are only used to describe specific exemplary configurations and are not intended to be limited. As used herein, the singular articles "one", "an" and "the" may also be intended to include plural forms, unless it is clearly indicated above that this is not the case. The terms "comprise", "include" and "have" are inclusive, and therefore specify the presence of features, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components and / or combinations thereof. The method steps, processes and operations described herein should not be interpreted as necessarily requiring them to be performed in the specific order discussed or shown, unless specifically identified as an execution order. Additional or alternative steps may be adopted.

[0071] As used herein, the phrases "in one embodiment," "according to one embodiment," "in some embodiments," and the like generally refer to the fact that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present disclosure. Therefore, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, so that these phrases do not necessarily refer to the same embodiment. As used herein, the terms "example," "exemplary," and the like are used to "serve as an example, instance, or illustration."

On the contrary, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0072] After research, it was found that the shortcomings of the prior art are as follows: when the packaging bottle is in contact with the demoulding mechanism, the packaging bottle and the demoulding structure are clamped tightly, which will cause the packaging bottle to be unable to detach from the demoulding mechanism after it is detached from the multi-station turntable; and when the packaging bottle and the demoulding structure are clamped loosely, the packaging bottle cannot maintain a horizontal state, and when the demoulding structure is flipped toward the conveyor belt, the packaging bottle will fall from the demoulding structure.

[0073] Therefore, how to solve the problem of how to quickly move the packaging bottle to the conveyor belt when it contacts the demoulding mechanism is a technical problem that needs to be solved urgently in the art.

[0074] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

[0075] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0076] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0077] like Figures 1 to 6 As shown, some embodiments provide a demoulding mechanism for a packaging bottle injection blow molding machine, comprising:

[0078] The multi-station turntable 1 is rotatably arranged on the operating table; the demoulding device 2 is slidably arranged on the side wall of the operating table and is suitable for flipping relative to the operating table; after the packaging bottle 4 is conveyed to the demoulding device 2, the demoulding device 2 moves outward relative to the operating table until the packaging bottle 4 moves above the conveyor belt 3, and the demoulding assembly 24 flips downward relative to the operating table to place the packaging bottle 4 on the conveyor belt 3. The conveyor belt 3 is arranged below the demoulding device 2, and the conveyor belt 3 is suitable for driving the packaging bottle 4 to move in a vertical state; the conveyor belt 3 and the demoulding plate 23 are parallel to each other. After the packaging bottle 4 is formed, the multi-station turntable 1 is rotated circumferentially to move the packaging bottle 4 to the demoulding device 2; the demoulding device 2 flips toward the conveyor belt 3 until the bottom wall of the packaging bottle 4 abuts against the conveyor belt 3, so that the packaging bottle 4 is separated from the demoulding device 2. By setting the demoulding device 2, when the packaging bottle 4 is placed horizontally on the demoulding member 242, the demoulding member 242 can limit the packaging bottle 4 to prevent the packaging bottle 4 from being separated from the demoulding plate 23 during the process of separating from the multi-station turntable 1 or the demoulding member 242 being turned over; and when the demoulding member 242 moves upward, the limiting plate 243 can push the packaging bottle 4 to move downward, avoiding the situation where the packaging bottle 4 is clamped too tightly by the demoulding member 242 and cannot be unloaded normally, thereby improving the unloading efficiency.

[0079] Reference Figure 2The demoulding device 2 comprises: a horizontal moving pair 21, which is arranged on the side wall of the operating table close to the conveyor belt 3; the horizontal moving pair 21 is suitable for driving the demoulding base 22 to move horizontally. The demoulding base 22 is arranged at the movable end of the horizontal moving pair 21; a demoulding plate 23, which is hinged on the demoulding base 22 and has a plurality of receiving grooves suitable for placing the packaging bottle 4; a driving motor 25 is arranged on the demoulding base 22, and the demoulding plate 23 is connected to the driving motor 25. The driving motor 25 is suitable for driving the demoulding plate 23 to flip it relative to the demoulding base 22 toward the conveyor belt 3; a plurality of demoulding components 24, which are arranged horizontally on the demoulding plate 23 and open upward, and one demoulding component 24 corresponds to one receiving groove; after the packaging bottle 4 is horizontally placed on the demoulding component 24, the demoulding plate 23 moves horizontally outward to make the packaging bottle 4 detach from the multi-station turntable 1, and after the packaging bottle 4 detaches, the demoulding component 24 is suitable for limiting the packaging bottle 4 to prevent it from falling downward. After the packaging bottle 4 is placed on the demoulding assembly 24, the demoulding assembly 24 is suitable for limiting the packaging bottle 4; the demoulding assembly 24 drives the packaging bottle 4 to flip downward until the packaging bottle 4 is in a vertical state. At this time, the packaging bottle 4 will not be separated from the demoulding assembly 24. After the horizontal moving auxiliary drives the demoulding plate 23 to move above the conveyor belt 3, the demoulding plate 23 flips toward the conveyor belt 3. When the bottom wall of the demoulding plate 23 abuts against the conveyor belt 3, the conveyor belt 3 pushes the demoulding plate 23 to move upward. At this time, the limiting plate 243 abuts against the upper end of the packaging bottle 4, so that the packaging bottle 4 is separated from the demoulding member 242, so that the packaging bottle 4 is placed on the conveyor belt 3.

[0080] Reference Figure 3 Specifically, the demolding assembly 24 includes: a positioning piece 241, which is arranged on the side wall of the demolding plate 23 and is in an arc shape; the positioning piece 241 is fixed in the receiving groove, and the packaging bottle 4 is suitable for sliding on the positioning piece 241. The demoulding piece 242 is slidably arranged in the positioning piece 241 and is suitable for rotating relative to the positioning piece 241; the demoulding piece 242 is in an arc shape and is arranged on the inner circle of the positioning piece 241, and the demoulding piece 242 is linked with the positioning piece 241; wherein, after the packaging bottle 4 is placed in the demoulding piece 242, the demoulding piece 242 is suitable for limiting the packaging bottle 4; the demoulding plate 23 is turned toward the conveyor belt 3 until the demoulding piece 242 abuts against the conveyor belt 3, at this time, the bottom wall of the packaging bottle 4 is still at a certain distance from the surface of the conveyor belt 3; the demoulding piece 242 is pushed upward by the conveyor belt 3, and the demoulding piece 242 drives the packaging bottle 4 to move upward synchronously until the upper end of the packaging bottle 4 abuts against the limiting plate 243, at this time, the limiting plate 243 is suitable for pushing the packaging bottle 4 to make it move downward relative to the demoulding piece 242, and the packaging bottle 4 is separated from the demoulding piece 242 and falls on the conveyor belt 3 in a vertical state.

[0081] Reference Figure 6Specifically, when the demolding member 242 is pushed upward by the conveyor belt 3, the demolding member 242 rotates relative to the positioning piece 241. At this time, the end wall of the demolding member 242 changes from being parallel to the conveyor belt 3 to being at an acute angle to the conveyor belt 3. The rotation of the demolding member 242 assists the packaging bottle 4 when the packaging bottle 4 falls on the conveyor belt 3, thereby preventing the packaging bottle 4 from being unstable and falling due to the horizontal movement of the conveyor belt 3 when the packaging bottle 4 initially contacts the conveyor belt 3.

[0082] Furthermore, a limiting plate 243 is provided at one end of the positioning plate 241 close to the multi-station turntable 1, and the limiting plate 243 is adapted to abut against the upper end wall of the packaging bottle 4. When the packaging bottle 4 is placed in the demoulding member 242, the packaging bottle 4 is clamped and limited by the limiting plate 244. At this time, there is a gap between the upper end of the packaging bottle 4 and the limiting plate 243, and synchronously, the lower end of the packaging bottle 4 is contracted in the demoulding member 242. A limiting plate 244 is fixed to the inner wall of the demoulding member 242, and the limiting plate 244 is adapted to clamp the neck of the packaging bottle 4.

[0083] Reference Figure 3 Preferably, a guide groove 245 is provided on the side wall of the demolding member 242, and the guide groove 245 is spiral; a limiting column 246 adapted to the guide groove 245 is fixed to the inner wall of the positioning plate 241, and the limiting column 246 is suitable for sliding in the guide groove 245; wherein, when the driving motor 25 drives the demolding plate 23 to flip it toward the direction of the conveyor belt 3 until the bottom wall of the demolding member 242 abuts against the conveyor belt 3, as the demolding plate 23 continues to flip downward, the demolding member 242 is squeezed by the conveyor belt 3 and moves upward, and when the demolding member 242 moves toward the direction of the limiting plate 243, the limiting column 246 is suitable for pushing the demolding member 242 to rotate the demolding member 242 relative to the positioning plate 241. The length of the demoulding member 242 is not less than the height of the packaging bottle 4, wherein the demoulding member 242 abuts against the conveyor belt 3, and the demoulding member 242 is pushed by the conveyor belt 3 to continue to move upward, and the limiting plate 243 is suitable for pushing the packaging bottle 4 to move downward.
