Detailed Description
Embodiments of the invention are described in detail below with reference to the attached drawing figures, but the invention can be practiced in a number of different ways, as defined and covered below.
According to one aspect of the present invention, there is provided a multi-row continuous injection molding apparatus including a plasticizing glue injection device 100, the plasticizing glue injection device 100 being followed by a plurality of rows of bottle embryo preparation devices 200, the multi-row continuous injection molding apparatus further including:
the splitting device comprises a communication main pipe connected with the outlet of the plasticizing glue injection device 100, a plurality of communication branch pipes respectively connected with the communication main pipe, and a switch component 411 for conducting each communication branch pipe, wherein the communication branch pipes are correspondingly connected with the multi-row bottle embryo preparation device 200 one by one;
The temperature-adjusting mold stripping device 400 is connected with the bottle embryo preparation device 200, and the temperature-adjusting mold stripping device 400 is used for heating and preserving the bottle embryo prepared by the bottle embryo preparation device 200 and driving the bottle embryo to be transported to the next working procedure along the one-dimensional linear direction.
It can be understood that the multiple rows of bottle embryo preparation devices 200 are communicated with the plasticizing glue injection device 100 through the splitting device, wherein a communicating main pipe of the splitting device is connected with the plasticizing glue injection device 100, and communicating branch pipes divide the communicating main pipe and are communicated with the bottle embryo preparation devices 200 of each row, meanwhile, when each communicating branch pipe is opened or closed through the switch component 411, the plasticizing glue injection device 100 is sequentially injected into the bottle embryo preparation devices 200 of each row, and injection can be timely performed again after the bottle embryo preparation devices 200 of each row finish embryo taking, so continuous injection is realized, and overlong time neutral gear is avoided. In addition, the temperature-adjusting mold stripping device 400 is used for realizing that the blank discharging transfer process of the bottle blank is completely in linear motion for transfer, and the optimal horizontal linear motion is selected, so that excessive heat loss caused by overlong exposure time of the bottle blank in the air due to a multi-dimensional movement route of deviation or turning is avoided, the transfer efficiency is greatly improved, and the extra heat supplementing process is avoided, so that the productivity is further improved; meanwhile, the temperature adjusting mechanism 405 of the temperature adjusting and demolding device 400 can also play a role in heating the bottle blanks in the process of carrying out linear transportation on the bottle blanks, ensures that the temperature of the bottle blanks is in a proper range, and is beneficial to the quality of subsequent bottle blowing.
The invention can effectively compress the exposure time of bottle blanks between blank ejection and pre-blowing or bottle blowing, the bottle blanks and injection molding are output in the same direction and are transmitted in a straight line, the bottle blanks are not deviated left and right and are not deviated up and down when being transported, the transmission time can be reduced as much as possible, and the shorter the time of the bottle blanks exposed in the air is, the more favorable for bottle blowing. In the preferred embodiment, the switch assembly 411 includes a rotary valve or solenoid valve, each of which can be used to open each of the communicating branches to perform the function of alternating injections. In addition, it should be noted that the preform preparing apparatus 200 includes a preform mold, and the preform mold and the plasticizing glue injection apparatus 100 are both related art and are not described herein.
The more compact continuous work is realized through the flow dividing device, and the production efficiency is further improved. Taking two rows of bottle embryo preparation devices 200 as an example, please refer to fig. 5, a plasticizing screw of the plasticizing glue injection device 100 is continuously plasticized, a tee joint 410 is communicated with the plasticizing glue injection device 100, the tee joint 410 is provided with two communicating branched pipes, the two communicating branched pipes are respectively communicated with a first glue injection cylinder and a second glue injection cylinder, the first glue injection cylinder and the second glue injection cylinder are respectively connected with the bottle embryo preparation device 200 in one row, and a switch component 411 controls the opening and closing of the two communicating branched pipes: assuming that the communicating branch pipe of the first glue injection cylinder is opened first, plasticized materials are injected into the first glue injection cylinder first, after the first glue injection cylinder is full, the switch component 411 closes the communicating branch pipe of the first glue injection cylinder and opens the communicating branch pipe of the second glue injection cylinder, at this time, the first glue injection cylinder can perform injection (pushing by the push rod 414), pressure maintaining is performed, the second glue injection cylinder is also full when the pressure maintaining is completed, the switch component 411 closes the communicating branch pipe of the second glue injection cylinder and opens the communicating branch pipe of one glue injection cylinder, the first glue injection cylinder starts feeding, the second glue injection cylinder can start injection, and the above steps are performed alternately. By matching the temperature-adjusting mold stripping device 400 with a mechanical arm, embryo taking can be realized to the next process, so that time-staggered work, namely, injection molding and embryo taking are equal, and continuous production with seamless connection is truly realized.
Of course, the present invention does not exclude the scheme of directly connecting the plasticizing glue injection device 100 with the bottle embryo preparation device 200 without using a split device, and at this time, continuous injection molding of each row of bottle embryo preparation devices 200 can be realized by controlling the opening of different plasticizing glue injection devices 100.
Preferably, referring to fig. 1, 3 and 4, the temperature-adjusting mold stripping device 400 includes a temperature-adjusting mechanism 405 and a transferring mechanism connected to the temperature-adjusting mechanism 405 for driving the temperature-adjusting mechanism 405 to move; the temperature adjusting mechanism 405 comprises a first temperature adjusting frame 408 and a second temperature adjusting frame Wen Kuang which are oppositely arranged, and a driving component for driving the first temperature adjusting frame 408 and the second temperature adjusting frame 409 to be close to each other or far away from each other, wherein the first temperature adjusting frame 408 and the second temperature adjusting frame Wen Kuang 409 are used for clamping and fixing the bottle embryo.
It can be understood that the temperature adjusting mechanism 405 can be driven by the transferring mechanism to perform linear motion, and the first temperature adjusting frame 408 and the second temperature adjusting frame 409 of the temperature adjusting mechanism 405 can perform relative displacement, so as to achieve a state similar to opening and closing, and clamp or loosen the bottle embryo, so that the bottle embryo is exposed in the opening state, the bottle embryo can be conveniently and quickly transferred to the next process by the mechanical arm in a straight line manner, the bottle embryo is not required to be clamped first to rise, then offset and translate, and finally the bottle embryo is placed in a downward moving manner, so that a large amount of displacement paths can be reduced, and the exposure time of the bottle embryo can be shortened. It should be noted that, the openable functions of the first temperature adjusting frame 408 and the second temperature adjusting frame 409 are to facilitate the linear transfer of the bottle embryo in the one-dimensional direction, so as to realize the transfer of the optimal route and reduce the exposure time. In the preferred embodiment, the preform product is directly dropped into the temperature adjustment mechanism 405 after the mold of the preform preparation apparatus 200 is opened, and then the linear motion is performed to complete the transfer.
Specifically, the opposite side walls of the first temperature adjusting frame 408 and the second temperature adjusting frame 409 are provided with a plurality of spacing grooves at intervals, the spacing grooves on the first temperature adjusting frame 408 and the second temperature adjusting frame Wen Kuang are combined in a one-to-one correspondence manner to form a plurality of spacing cavities, and the spacing cavities are matched with the bottle blanks and are used for clamping and fixing the bottle blanks.
It can be understood that the first temperature adjusting frame 408 and the second temperature adjusting frame Wen Kuang are provided with one-to-one corresponding limiting grooves, the limiting grooves on two sides are combined to form a limiting cavity to limit the bottle embryo, the first temperature adjusting frame 408 and the second temperature adjusting frame 409 can relatively displace, and the similar opening effect is realized, so that the bottle embryo is not limited any more so as to perform the rapid embryo taking transfer operation. Because the temperature adjusting mechanism 405 moves linearly and can be opened, the steps of upward movement and downward movement after translation are not needed when the bottle embryo is transferred linearly, the displacement route in the vertical direction is canceled, the transfer can be completed only by carrying out the fastest translation movement, and the transfer distance and the transfer time are effectively shortened.
Preferably, referring to fig. 2 and 3, the temperature adjusting mechanisms 405 are provided with a plurality of rows corresponding to the bottle embryo preparing device 200, the plurality of rows of temperature adjusting mechanisms 405 are arranged in pairs, two first temperature adjusting frames 408 in a pair of temperature adjusting mechanisms 405 are connected through a first linkage assembly, two second temperature adjusting frames 409 in the pair of temperature adjusting mechanisms 405 are connected through a second linkage assembly, the first linkage assembly is used for driving the corresponding two first temperature adjusting frames 408 to move synchronously, and the second linkage assembly is used for driving the corresponding two second temperature adjusting frames 409 to move synchronously.
Alternatively, the driving assembly includes two linear driving assemblies separately disposed on opposite sides of the pair of temperature adjusting mechanisms 405, wherein one linear driving assembly is connected to a first temperature adjusting frame 408 located at the outer side of the pair of temperature adjusting mechanisms 405, and the other linear driving assembly is connected to a second temperature adjusting frame 409 located at the outer side of the pair of temperature adjusting mechanisms 405.
It can be appreciated that the temperature adjusting mechanisms 405 arranged in pairs can simultaneously transfer bottle blanks discharged from the two rows of bottle blank preparation devices 200, so as to meet the requirement of transferring batch products. In the preferred embodiment, the linear drive assembly includes cylinders 406, and both cylinders 406 can each open one of the temperature adjustment mechanisms 405. Of course, the present invention does not exclude the following scheme, for example, two cylinders 406 are disposed between two rows of temperature adjusting mechanisms 405, so as to respectively drive the second temperature adjuster Wen Kuang of the first row of temperature adjusting mechanisms 405 and the first temperature adjusting frame 408 of the second row of temperature adjusting mechanisms 405 to displace; or a scheme of arranging a double-head cylinder between the two rows of temperature adjusting mechanisms 405 can also realize the opening function of the two rows of temperature adjusting mechanisms 405. In this case, the temperature adjusting mechanisms 405 are arranged in pairs, however, the same manner can also be used to connect three or more rows of temperature adjusting mechanisms simultaneously through the first linkage assembly and the second linkage assembly, and the two linear driving assemblies drive each temperature adjusting mechanism 405 to open.
Optionally, the first linkage assembly includes a first guide link, and the second linkage assembly includes a second guide link, where the first guide link is configured to penetrate through the second temperature adjusting frame 409 of the first row of temperature adjusting mechanisms 405 and connect the first row with the two first temperature adjusting frames 408 of the second row of temperature adjusting mechanisms 405, and the second guide link is configured to penetrate through the first temperature adjusting frame 408 of the second row of temperature adjusting mechanisms 405 and connect the first row with the two second temperature adjusting frames 409 of the second row of temperature adjusting mechanisms 405.
It can be appreciated that the first guide connecting rod and the second guide connecting rod not only play a role in connection, but also play a role in guiding, so that the driving assembly is guaranteed to drive the first temperature adjusting frame 408 and the second temperature adjusting frame Wen Kuang to perform more stable translational movement, and the limit grooves of the relative positions on the first temperature adjusting frame 408 and the second temperature adjusting frame Wen Kuang 409 are guaranteed not to be greatly offset, the accuracy of the positions of the limit grooves in the movement process is guaranteed, and the limit cavity is formed by smooth combination to stably limit bottle blanks.
In another scheme, the temperature adjusting mechanism 405 is provided with a plurality of rows corresponding to the bottle embryo preparation device 200, the temperature adjusting mechanisms 405 in pairs are arranged in a plurality of rows, the driving assembly is connected with one of the first temperature adjusting frames 408 in the pair of temperature adjusting mechanisms 405, the two first temperature adjusting frames 408 in the pair of temperature adjusting mechanisms 405 are connected through a first linkage assembly, the first linkage assembly is used for driving the corresponding two first temperature adjusting frames 408 to synchronously move, and the second temperature adjusting Wen Kuang 409,409 is fixedly arranged on the transfer mechanism.
It can be appreciated that the first temperature adjusting frames 408 between the two temperature adjusting mechanisms 405 arranged in pairs are connected through a first linkage assembly, the first linkage assembly comprises a first guide rod, one of the first temperature adjusting frames 408 is driven to move through a driving assembly, and the two rows of temperature adjusting mechanisms 405 can be synchronously driven to clamp or loosen bottle blanks, so that more efficient transfer is realized.
It should be noted that, the temperature adjusting mechanisms 405 arranged in pairs are not limited to the two-to-two arrangement, and each temperature adjusting mechanism 405 arranged in multiple rows can adapt to the transferring requirement of bottle blanks with different rows under different working conditions, at this time, only the first temperature adjusting frames 408 or the second temperature adjusting frames 409 of each row of temperature adjusting mechanisms 405 are connected with each other through the linkage assembly 415 (the linkage assembly 415 adopts a straight rod, etc.), and one of the first temperature adjusting frames 408 or the second temperature adjusting frames Wen Kuang can be driven by the cylinder 406 of the driving assembly to realize synchronous opening of each row of temperature adjusting mechanisms 405.
Optionally, the driving assembly includes a baffle plate disposed at the bottom or top of the first temperature adjusting frame 408 and/or the second temperature adjusting frame Wen Kuang, a stop lever disposed in the linear motion direction of the first temperature adjusting frame 408 and/or the second temperature adjusting frame 409, and a spring connecting the first temperature adjusting frame 408 and the second temperature adjusting frame Wen Kuang, where the stop lever is disposed corresponding to the baffle plate, and the baffle plate is disposed in an inclined manner or one side of the baffle plate is an inclined plane, and when the baffle plate contacts the stop lever in the linear motion process of the first temperature adjusting frame 408 and the second temperature adjusting frame 409, the inclined baffle plate or the inclined plane of the baffle plate pushes the first temperature adjusting frame 408 and/or the second temperature adjusting frame Wen Kuang to be away from each other in the sliding contact process of the baffle lever, so that the bottle blank is exposed from the limiting cavity. Because the temperature adjusting mechanism 405 reciprocates along a straight line, when the baffle is separated from the baffle rod, the first temperature adjusting frame 408 and the second temperature adjusting frame Wen Kuang can be tensioned by a spring to form a heat preservation cavity. Therefore, the first temperature adjusting frame 408 and the second temperature adjusting frame Wen Kuang can be opened without an active driving device such as a motor or a linear cylinder, thereby being beneficial to saving energy and reducing cost.
Preferably, as shown in fig. 6, a heat insulation pad and a heating component connected with the heat insulation pad are disposed in the first temperature adjusting frame 408 and/or the second temperature adjusting frame 409.
It can be appreciated that the heating assembly can maintain the overall temperature of the first temperature adjusting frame 408 and the second temperature adjusting frame 409, so that the temperature of the bottle embryo is not conducted and transferred rapidly when the first temperature adjusting frame 408 and the second temperature adjusting frame Wen Kuang clamp the limiting bottle embryo, and the bottle embryo is cooled rapidly, so that the quality of the subsequent bottle blowing is affected.
