Description

Technical Field

[0001] The invention relates to the field of plastic processing, in particular to a bottle blowing machine. Background Art

[0002] The existing bottle blowing machine includes a frame and a heating structure, a spacing structure, a conveying structure, a bottle blowing structure and a mold clamping structure arranged on the frame. During processing, the heating structure heats and softens the preform, the conveying structure inputs the softened preform into the mold clamping structure, and the bottle blowing structure blows the preform clamped in the mold clamping structure. The spacing structure receives the heated and softened preform and spaces it to a spacing that matches each mold cavity in the mold clamping structure, so that the conveying structure can transfer the preform. The top of the preform includes a clamping station arranged on the side and an insertion station arranged on the top. On the one hand, in order to shorten the length of the heating channel in the heating structure, the preform is suspended by the insertion station, and the output of softened preforms is increased by reducing the distance between adjacent preforms. To this end, the spacing structure receives the softened preforms through the clamping assembly. On the other hand, since a bottle blowing structure is provided on the top of the mold structure, in order to avoid the bottle blowing structure, the conveying structure will also receive the preforms from the spacing structure through the clamping assembly. This results in the need to share the clamping station when the preforms are transferred between the spacing structure and the conveying structure, which not only puts forward high requirements on the movement accuracy of the clamping assembly, but also affects the clamping stability due to the reduction in the area of ​​the clamping station that can be contacted by each clamping assembly, and even causes the preform to deviate from the preset transfer position and cause subsequent bottle blowing failure, affecting the user experience. Summary of the invention

[0003] In order to address the deficiencies in the prior art, the present invention provides a bottle blowing machine with a transfer mechanism. The transfer mechanism is arranged between the spacing structure and the conveying structure. The transfer mechanism is used to realize the connection of the preform by switching between the clamping station and the insertion station, so that the spacing structure and the conveying structure can use the same station at different times, which not only reduces the requirements for movement accuracy, but also improves the connection stability and enhances the user experience.

[0004] The present invention is realized in the following manner: a bottle blowing machine with a transfer mechanism comprises a frame and a heating structure, a spacing structure, a conveying structure, a bottle blowing structure and a mold closing structure arranged on the frame, the spacing structure receives bottle blanks from the heating structure and disperses them to a preset spacing, so that the conveying structure receives bottle blanks that are equidistantly spaced and feeds them into the mold closing structure, a transfer mechanism for transferring bottle blanks is arranged between the spacing structure and the conveying structure, a clamping station for lateral clamping and an insertion station for vertical insertion are arranged on the top of the bottle blank, and the bottle blank is rotated and connected through the clamping station and the insertion station when being transferred between the spacing structure, the transfer mechanism and the conveying structure in sequence. A transfer mechanism is set between the spacing structure and the conveying structure, and the transfer mechanism is used to realize the connection of the preform by switching between the clamping station and the insertion station. The transfer mechanism can provide positioning for the preform during the conversion connection, so that the spacing structure and the conveying structure can use the same station at different times, without having to have high requirements for movement accuracy in order to avoid each other, reducing production difficulty, improving processing efficiency, and reducing processing costs. The connection stability is improved by increasing the contact area between the preform and the conveying structure and between the preform and the spacing structure, thereby improving the transfer accuracy of the preform, preventing the preform from affecting the subsequent processing quality due to offset, and improving the user experience. When the preform is transferred from the spacing structure to the transfer mechanism and when the preform is transferred from the transfer mechanism to the conveying structure, the station used for the connection of the preform will switch between the clamping station and the insertion station, ensuring that the spacing structure and the conveying structure can independently use the corresponding connection station at different times. The top outer side wall of the preform forms a clamping station for clamping, and the open inner edge of the top surface of the preform forms an inserting station for inserting, so that the clamping station and the inserting station have different working areas.

[0005] Preferably, the spacing structure, the transfer mechanism and the conveying structure are all provided with a transfer component, and the transfer component is a clamping component that can match the clamping station or an insertion component that can cooperate with the plug-in station. The spacing structure and the transfer mechanism are respectively provided with a clamping component and an insertion component, and the conveying structure is provided with a transfer component identical to the spacing structure. The spacing structure, the transfer mechanism and the conveying structure all realize bottle blank transportation through corresponding transfer components. Specifically, in order to ensure the working efficiency of the bottle blowing machine, the spacing structure and the conveying structure use the same transfer component, and the spacing mechanism uses another transfer component.

[0006] Preferably, the spacing structure and the conveying structure are both provided with a clamping assembly, and the transfer mechanism is provided with an insertion assembly. The transfer mechanism is connected to the preform through the insertion assembly, so that the spacing structure is separated from the clamping station, and it is convenient for the conveying structure to connect the preform through the clamping station, and it is convenient to transfer the preform from the spacing structure to the conveying structure.

[0007] Preferably, the transfer mechanism comprises a support fixed to the frame, a transfer plate escalably arranged below the support, and a driving member driving the transfer plate to be raised or lowered, the insertion assembly is arranged on the transfer plate, and when the driving member drives the transfer plate to descend, the insertion assembly is vertically linked with the transfer plate and matched with the insertion station to transfer the preform between the spacing structure and the conveying structure in an inserted and suspended state. The support is arranged at the junction of the spacing structure and the conveying structure, so that the preform can be suspended at the junction under the action of the insertion assembly, ensuring that the clamping station of the preform is idle and providing convenience for the conveying structure to clamp the preform at different times.

[0008] Preferably, a vertical guide rail is provided below the support, and a slider is provided on the transfer plate, which is lifted and lowered along the guide rail so that the transfer plate can be lifted and lowered in a horizontal posture. The guide rail plays a limiting and guiding role in the lifting and lowering of the transfer plate, thereby ensuring that the plug-in assembly can be lifted and lowered vertically and connected with the preform, ensuring that the preform is always located at the connection station, and facilitating the transfer of the preform between the spacing structure and the conveying structure.

[0009] Preferably, the bottom surface of the support extends downward to form a guide plate, and the guide rail is arranged on the side wall of the guide plate. The guide plate is arranged vertically to prevent the transfer plate from being offset due to shaking of the guide rail, thereby ensuring the movement accuracy of the insertion component.

[0010] Preferably, the top edge of the transfer plate extends upward to form a connecting plate, and the slider is arranged on the side wall of the connecting plate. The connecting plate plays a positioning role for the slider, ensuring that the relative position between the transfer plate and the slider is fixed, thereby ensuring that the transfer plate can be lifted and lowered in a horizontal posture.

[0011] Preferably, there are at least two guide rails, which are arranged separately. By increasing the number of guide rails, the moving accuracy of the transfer plate is improved to prevent the transfer plate from shaking.

[0012] Preferably, the driving member is a vertically arranged cylinder, which includes a cylinder body fixed to the support and a telescopic rod fixed to the transfer plate, and the telescopic rod is telescopically connected to the cylinder body to vertically lift the transfer plate. The cylinder can share the air source with the bottle blowing structure, which is convenient for installation and use. At this time, the movement range of the telescopic rod is controlled, which not only ensures that the insertion component can be accurately connected to the preform, but also effectively prevents the preform from being damaged due to excessive displacement of the telescopic rod.

[0013] Preferably, the plug-in assembly includes a plurality of plug-in parts arranged equidistantly in a straight line, the top end of the plug-in parts is fixedly connected to the transfer plate, and the bottom end forms a plug-in joint that cooperates with the plug-in station. The bottom end of the plug-in part is inserted into the opening of the preform from top to bottom, and the preform is suspended by the opening, so that the clamping station is exposed, and the transfer between the spacing structure and the conveying structure is realized.

[0014] Preferably, a right angle frame is provided between the support and the frame, the bottom surface of the right angle frame is fixedly connected to the top surface of the support, and the side wall is fixedly connected to the frame. The right angle frame limits the support, ensures that the support maintains a horizontal posture, and ensures that the transfer plate and the plug-in assembly move along a preset path.

The transfer mechanism is connected to the preform through the clamping assembly, so that the spacing structure is separated from the insertion station, and it is convenient for the conveying structure to connect the preform through the insertion station, so that the preform is conveniently transferred from the spacing structure to the conveying structure.

The transfer mechanism can provide positioning for the bottle blank during the conversion connection, so that the spacing structure and the conveying structure can use the same station at different times.

The connection stability is improved by increasing the contact area between the bottle blank and the conveying structure and between the bottle blank and the spacing structure, thereby improving the transfer accuracy of the bottle blank, preventing the bottle blank from affecting the subsequent processing quality due to offset, and improving the user experience.

DETAILED DESCRIPTION

[0020] The essential features of the present invention are further described below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figure 1 and 2The bottle blowing machine with a transfer mechanism shown in the figure is composed of a frame 1 and a heating structure 2, a spacing structure 3, a conveying structure 4, a bottle blowing structure 5 and a clamping structure 6 arranged on the frame 1. The spacing structure 3 receives the bottle blanks from the heating structure 2 and disperses them to a preset spacing, so that the conveying structure 4 receives the bottle blanks that are equidistantly spaced and feeds them into the clamping structure 6. A transfer mechanism 7 for transferring the bottle blanks is arranged between the spacing structure 3 and the conveying structure 4. A clamping station for lateral clamping and an insertion station for vertical insertion are arranged on the top of the bottle blank. The bottle blanks are rotated and connected by the clamping station and the insertion station when they are transferred among the spacing structure 3, the transfer mechanism 7 and the conveying structure 4 in sequence. A transfer mechanism 7 is arranged between the spacing structure 3 and the conveying structure 4. The transfer mechanism 7 is used to realize the connection of the preform by switching between the clamping station and the insertion station. The transfer mechanism 7 can provide positioning for the preform during the conversion and connection, so that the spacing structure 3 and the conveying structure 4 can use the same station at different times. There is no need to have high requirements on the movement accuracy in order to avoid each other, which reduces the production difficulty, improves the processing efficiency, and reduces the processing cost. The connection stability is improved by increasing the contact area between the preform and the conveying structure 4 and between the preform and the spacing structure 3, thereby improving the transfer accuracy of the preform, preventing the preform from affecting the subsequent processing quality due to offset, and improving the user experience.

[0022] In actual operation, the spacing structure 3, the transfer mechanism 7 and the conveying structure 4 are all provided with a transfer component, and the transfer component is a clamping component that can match the clamping station or an insertion component that can cooperate with the insertion station. The spacing structure 3 and the transfer mechanism 7 are respectively provided with a clamping component and an insertion component, and the conveying structure 4 is provided with a transfer component that is the same as the spacing structure 3. Specifically, the spacing structure 3 and the conveying structure 4 are both provided with a clamping component, and the transfer mechanism 7 is provided with an insertion component. The preform is connected with the corresponding components through the clamping station and the insertion station, so that the preform is transferred in sequence between the spacing structure 3, the transfer mechanism 7 and the conveying structure 4.

[0023] In actual operation, the mold closing structure 6 includes mold plates that can be matched and opened and closed, and a plurality of mold cavities are arranged between the mold plates. The preforms output from the heating structure 2 are conveyed to the mold closing structure 6 through the following steps, specifically:

[0024] First, the bottle blank is clamped on the spacing structure 3 by a clamping assembly cooperating with the clamping station;

[0025] Afterwards, the spacing structure 3 performs spacing operation on the closely arranged preforms so that the distance between adjacent preforms matches the distance between adjacent mold cavities. At this time, the insertion station of the preforms is in an idle state;

[0026] Then, the transfer mechanism 7 is inserted into the insertion station of the bottle blank through the insertion component moving downward, so that the bottle blank is suspended and positioned by the insertion component, and the spacing structure 3 plays a vertical limiting role on the bottle blank to ensure that the insertion component is smoothly inserted into the bottle blank. At this time, the clamping station of the bottle blank is in an idle state;

[0027] Then, the conveying structure 4 clamps the preform through the clamping assembly, and the insertion assembly plays a horizontal limiting role on the preform, ensuring that the clamping assembly can smoothly grab the preform;

[0028] Then, the insertion assembly moves upward and separates from the preform, and the clamping assembly of the conveying structure 4 plays a vertical limiting role on the preform to ensure that the preform and the insertion assembly are separated smoothly;

[0029] Finally, the preform is transported by the transport structure 4 to the mold closing structure 6 .

[0030] The bottle blanks are transferred by the above steps, so that both the spacing structure 3 and the conveying structure 4 can grab the bottle blanks through the clamping station. Since the spacing structure 3 and the conveying structure 4 are transferred through the transfer mechanism 7, there is no time period when the spacing structure 3 and the conveying structure 4 grab the clamping station at the same time. The staggered grabbing ensures that the clamping components of the spacing structure 3 and the conveying structure 4 can completely and stably clamp the bottle blanks.

[0031] In actual operation, the spacing structure 3 moves the bottle blank to the transfer position, and the transfer mechanism 7 plays a role in positioning and transferring the bottle blank, so that the bottle blank is always located at the transfer position during the transfer period. The conveying structure 4 clamps the bottle blank located at the transfer position through the clamping assembly to ensure that the bottle blank is transferred from the spacing structure 3 to the conveying structure 4.

[0032] In the actual operation group, the transfer mechanism 7 includes a support 8 fixed to the frame 1, a transfer plate 10 escalably arranged below the support 8, and a driving member driving the transfer plate 10 to be raised and lowered. The insertion assembly is arranged on the transfer plate 10. When the driving member drives the transfer plate 10 to descend, the insertion assembly is vertically linked with the transfer plate 10 and matched with the insertion station to transfer the preform in an inserted and suspended state between the spacing structure 3 and the conveying structure 4. The support 8 is fixed to the frame 1, thereby ensuring that the transfer plate 10 and the insertion assembly can be smoothly raised and lowered along the preset path.

[0033] In actual operation, in order to improve the movement accuracy of the transfer plate 10 and the insertion component, a vertical guide rail 11 is provided below the support 8, and a slider 13 is provided on the transfer plate 10. The slider 13 is lifted and lowered along the guide rail 11, so that the transfer plate 10 is lifted and lowered in a horizontal posture. Specifically, the bottom surface of the support 8 extends downward to form a guide plate 15, the guide rail 11 is arranged on the side wall of the guide plate 15, the top edge of the transfer plate 10 extends upward to form a connecting plate 14, and the slider 13 is arranged on the side wall of the connecting plate 14. The guide plate 15 and the support 8, the connecting plate 14 and the transfer plate 10 are all arranged perpendicular to each other, which not only effectively improves the connection strength between the support 8 and the guide rail 11, and between the slider 13 and the transfer plate 10, but also ensures that the insertion component is lifted and lowered vertically along its axis.

[0034] In actual operation, there are at least two guide rails 11, which are separately arranged. The guide rails 11 are separately arranged on both sides of the support 8, and the lifting stability of the transfer plate 10 is improved by increasing the distance between the guide rails 11.

[0035] In actual operation, the driving member is a vertically arranged cylinder 12, which includes a cylinder body fixed on the support 8 and a telescopic rod fixed to the transfer plate 10, and the telescopic rod is telescopically connected to the cylinder body to vertically lift the transfer plate 10. The telescopic rod can be vertically extended and retracted along its axis to synchronously lift the transfer plate 10, effectively cooperating with the spacing structure 3 and the conveying structure 4 to achieve the transfer of the preform. In addition, the driving member can also be other structures, such as a screw and a rack driven by a private service motor, which should be regarded as specific embodiments of the present invention.

[0036] In actual operation, the plug assembly includes a plurality of plugs arranged equidistantly in a straight line, the top of the plug is fixedly connected to the transfer plate 10, and the bottom forms a plug connector 9 that cooperates with the plug station. The number and relative positions of the plugs correspond to the number and relative positions of the mold cavities, ensuring that the preforms are separated to the transfer station before being received by the conveying structure 4, meeting the requirements of the mold closing and bottle blowing operation.

[0037] In actual operation, a right angle frame 16 is provided between the support 8 and the frame 1, the bottom surface of the right angle frame 16 is fixedly connected to the top surface of the support 8, and the side wall is fixedly connected to the frame 1. One side of the support 8 is fixedly connected to the frame 1, and the right angle frame 16 is used to improve the connection strength between the support 8 and the frame 1, thereby ensuring that the support 8 is always in a horizontal posture.

[0038] In actual operation, the spacing structure 3 and the conveying structure 4 are both provided with an insertion component, and the transfer mechanism 7 is provided with a clamping component. The preform can also be connected with the corresponding components through the clamping station and the insertion station, so that the preform can be transferred in sequence between the spacing structure 3, the transfer mechanism 7 and the conveying structure 4, which should also be regarded as a specific embodiment of the present invention.
