Description

A multi-row continuous injection molding equipment and bottle blowing production line Technical Field

[0001] The present invention relates to the technical field of plastic bottle production, in particular to a multi-row continuous injection molding device. In addition, the present invention also relates to a bottle blowing production line comprising the multi-row continuous injection molding device. Background Art

[0002] Plastic bottles are a common container with a huge demand and are used in a wide range of fields, such as food and beverages, medical containers, medicine bottles, seasoning containers, etc.

[0003] The production process for plastic bottles includes a two-step method (commonly used in the early stages of the industry) and a one-step method. In recent years, the one-step method has gained increasing market recognition. For example, Chinese patent application number 202210194038.1 discloses a linear injection-blow-fill-seal integrated plastic bottle packaging device with high integration and high energy efficiency. However, in actual application, the above-mentioned device has been found to have difficulty in further increasing its production capacity. The main reasons include:

[0004] 1. It is not possible to carry out multi-row continuous injection molding, and there is a long working time gap, which makes it impossible to connect the subsequent processes to carry out continuous and efficient production of multiple batches;

[0005] 2. The preform preheating takes too much time because the transfer route between the preform ejection and the pre-blowing process is very long (after the preform is taken out by the robot, it needs to be offset, then lowered, and then transferred horizontally). As a result, the preform is exposed for a long time and loses a lot of heat, so it takes a long time to replenish the heat. The excessive time consumed in this link seriously affects production capacity.

[0006] Summary of the Invention

[0007] The present invention provides a multi-row continuous injection molding device to solve the technical problems that the existing device cannot perform continuous injection molding and the preform preheating time is too long.

[0013] Furthermore, a plurality of limiting grooves are spaced apart on the opposite side walls of the first temperature regulating frame and the second temperature regulating frame. The limiting grooves on the first temperature regulating frame and the second temperature regulating frame correspond to each other and are combined to form a plurality of limiting cavities. The limiting cavities are adapted to the bottle preform and are used to clamp and fix the bottle preform.

[0014] Furthermore, the temperature control mechanism is provided with multiple rows corresponding to the preform preparation device, and the multiple rows of temperature control mechanisms are arranged in pairs. The two first temperature control frames in a single pair of temperature control mechanisms are connected by a first linkage component, and the two second temperature control frames in a single pair of temperature control mechanisms are connected by a second linkage component. The first linkage component is used to drive the corresponding two first temperature control frames to move synchronously, and the second linkage component is used to drive the corresponding two second temperature control frames to move synchronously.

[0015] Furthermore, the drive assembly includes two linear drive assemblies arranged on opposite sides of a single pair of temperature control mechanisms, one of the linear drive assemblies is connected to a first temperature control frame located on the outside of the single pair of temperature control mechanisms, and the other linear drive assembly is connected to a second temperature control frame located on the outside of the single pair of temperature control mechanisms.

[0016] Furthermore, the first linkage assembly includes a first guide link and a second guide link of the second linkage assembly. The first guide link is used to pass through the second temperature control frame of the first row of temperature control mechanisms and connect the two first temperature control frames of the first row and the second row of temperature control mechanisms. The second guide link is used to pass through the first temperature control frame of the second row of temperature control mechanisms and connect the two second temperature control frames of the first row and the second row of temperature control mechanisms.

[0017] Furthermore, the temperature control mechanism is provided with multiple rows corresponding to the preform preparation device, and the multiple rows of temperature control mechanisms are arranged in pairs.

DETAILED DESCRIPTION

[0034] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0035] According to one aspect of the present invention, a multi-row continuous injection molding apparatus is provided, comprising a plasticizing injection molding apparatus 100, the plasticizing injection molding apparatus 100 being connected to a multi-row preform preparation apparatus 200, the multi-row continuous injection molding apparatus further comprising:

[0036] A flow diversion device, comprising a main communication pipe connected to the outlet of the plasticizing and injection device 100, a plurality of branch communication pipes respectively connected to the main communication pipe, and a switch assembly 411 for conducting each branch communication pipe. The plurality of branch communication pipes are connected one-to-one with the multiple rows of preform preparation devices 200;

[0037] The temperature-controlled demoulding device 400 is connected to the preform preparation device 200 and is used to heat and keep the preforms prepared by the preform preparation device 200 warm and drive the preforms to be transported along a one-dimensional straight line to the next process.

[0038] It can be understood that the plurality of rows of preform preparation devices 200 are connected to the plasticizing and injection molding devices 100 via the diverter device, wherein the main communication pipe of the diverter device is connected to the plasticizing and injection molding devices 100, and the branch communication pipes divert the main communication pipe and connect with each row of preform preparation devices 200. At the same time, the branch communication pipes are opened or closed by the switch assembly 411, so that the plasticizing and injection molding devices 100 can sequentially perform injection molding on each row of preform preparation devices 200. After each row of preform preparation devices 200 completes the removal of preforms, injection molding can be carried out in a timely manner, thereby achieving continuous injection molding and avoiding excessive idle time. In addition, the temperature-controlled ejection device 400 enables the preform to be transported completely in a linear motion, selecting the optimal horizontal linear motion to avoid deviations or turns in the multi-dimensional motion route, which would cause the preform to be exposed to the air for too long and lose too much heat. This greatly improves the efficiency of transportation and avoids the need for additional heat replenishment, thereby further increasing production capacity. At the same time, the temperature-controlled mechanism 405 of the temperature-controlled ejection device 400 can also heat the preform during the linear transport process, ensuring that the temperature of the preform is within an appropriate range, which is beneficial to the quality of subsequent bottle blowing.

[0039] It should be noted that the present invention can effectively shorten the exposure time of preforms between ejection and pre-blowing or bottle blowing. Preforms are ejected in the same direction as the injection molding process and transported in a straight line, ensuring that preforms are transported without deviation, either left or right, vertically. This minimizes transfer time, and the shorter the preform's exposure to air, the more conducive it is to bottle blowing. In this preferred embodiment, the switch assembly 411 comprises a rotary valve or a solenoid valve, both of which can be used to open the various connecting branches to achieve alternating injection. Furthermore, it should be noted that the preform preparation apparatus 200 includes a preform mold. Both the preform mold and the plasticizing and injection molding apparatus 100 are prior art and will not be further described here.

[0040] The diversion device achieves a more compact continuous operation and further improves production efficiency. Taking a two-row preform preparation device 200 as an example, please refer to Figure 5. A plasticizing screw of the plasticizing injection device 100 continuously plasticizes and is connected to the plasticizing injection device 100 through a tee 410. The tee 410 has two connecting pipes, which are respectively connected to the first injection cylinder and the second injection cylinder. The first injection cylinder and the second injection cylinder are respectively connected to a row of preform preparation devices 200. The switch component 411 controls the opening and closing of the two connecting pipes: assuming that the connecting pipe of the first injection cylinder is opened first, The plasticized material is first injected into the first shot-molding cylinder. When the first shot-molding cylinder is full, the switch assembly 411 closes the connecting branch of the first shot-molding cylinder and opens the connecting branch of the second shot-molding cylinder. The first shot-molding cylinder can now inject (the push rod 414 pushes to inject) and maintain pressure. When the pressure maintenance is completed, the second shot-molding cylinder is also full. The switch assembly 411 closes the connecting branch of the second shot-molding cylinder and opens the connecting branch of the first shot-molding cylinder. The first shot-molding cylinder begins feeding the material and the second shot-molding cylinder can begin injecting. This process is repeated alternately. The temperature-controlled ejection device 400 and the robot realize the ejection and removal of the embryo to the next process, which can achieve staggered operation, that is, the injection time and the ejection and removal time are equal, truly realizing seamless continuous production.

[0041] Of course, the present invention does not exclude the possibility of directly connecting the plasticizing injection device 100 to the preform preparation device 200 without using a diverter device. In this case, continuous injection molding of each row of preform preparation devices 200 can be achieved by controlling the opening of different plasticizing injection devices 100.

[0042] Preferably, referring to Figures 1, 3, and 4, the temperature-regulating ejection device 400 includes a temperature-regulating mechanism 405 and a transfer mechanism connected to the temperature-regulating mechanism 405 and used to drive the temperature-regulating mechanism 405 to move; the temperature-regulating mechanism 405 includes a first temperature-regulating frame 408 and a second temperature-regulating frame 409 arranged opposite to each other, and a drive assembly for driving the first temperature-regulating frame 408 and the second temperature-regulating frame 409 to move toward or away from each other; the first temperature-regulating frame 408 and the second temperature-regulating frame 409 are used to clamp and fix the bottle blank.

[0043] It is understood that the temperature control mechanism 405 can be driven by the transfer mechanism to perform linear motion, while the first and second temperature control frames 408, 409 of the temperature control mechanism 405 can be relatively displaced, achieving states similar to opening and closing, capable of clamping or releasing the preform. Thus, in the open state, the preform is exposed, facilitating rapid removal by the robot for linear transfer to the next process step. This eliminates the need to first clamp the preform, raise it, then offset it, then translate it, and finally lower it for placement. This significantly reduces displacement and shortens the exposure time of the preform. It should be noted that the ability of the first and second temperature control frames 408, 409 to be opened is intended to facilitate linear transport of the preform in one dimension, achieving an optimal transport route and reducing exposure time. In this preferred embodiment, after the mold of the preform preparation apparatus 200 is opened, the preform product falls directly into the temperature control mechanism 405, whereupon linear motion completes the transfer.

[0044] Specifically, a plurality of limiting grooves are provided on the opposite side walls of the first temperature regulating frame 408 and the second temperature regulating frame 409. The limiting grooves on the first temperature regulating frame 408 and the second temperature regulating frame 409 correspond to each other and are combined to form a plurality of limiting cavities. The limiting cavities are adapted to the preforms and are used to clamp and fix the preforms.

[0045] As can be understood, the first and second temperature control frames 408 and 409 each have corresponding limiting grooves. These grooves combine to form a limiting cavity, which holds and limits the preforms. The first and second temperature control frames 408 and 409 can move relative to each other, achieving a similar opening effect, freeing the preforms from being constrained, allowing for rapid preform removal and transfer. The linear motion and openable nature of the temperature control mechanism 405 ensures that preforms can be transported linearly without the steps of upward, horizontal, and then downward movement. This eliminates the need for vertical displacement, allowing transfer to be completed with only the fastest possible horizontal movement, effectively shortening both the distance and time required for transfer.

[0046] Preferably, referring to Figures 2 and 3, the temperature control mechanism 405 is provided with multiple rows corresponding to the preform preparation device 200, and the multiple rows of temperature control mechanisms 405 are arranged in pairs. The two first temperature control frames 408 in a single pair of temperature control mechanisms 405 are connected by a first linkage component, and the two second temperature control frames 409 in a single pair of temperature control mechanisms 405 are connected by a second linkage component. The first linkage component is used to drive the corresponding two first temperature control frames 408 to move synchronously, and the second linkage component is used to drive the corresponding two second temperature control frames 409 to move synchronously.

[0047] Optionally, the drive assembly includes two linear drive assemblies arranged on opposite sides of the single pair of temperature control mechanisms 405, one of the linear drive assemblies is connected to the first temperature control frame 408 located on the outside of the single pair of temperature control mechanisms 405, and the other linear drive assembly is connected to the second temperature control frame 409 located on the outside of the single pair of temperature control mechanisms 405.

[0048] It can be understood that the paired arrangement of the temperature control mechanisms 405 can simultaneously transport preforms discharged from two rows of preform preparation devices 200, meeting the needs of batch product transport. In this preferred embodiment, the linear drive assembly includes a cylinder 406, and the two cylinders 406 can each activate one of the temperature control mechanisms 405. Of course, the present invention does not exclude the following solutions: for example, the two cylinders 406 are arranged between the two rows of temperature control mechanisms 405, thereby respectively driving the displacement of the second temperature control frame 409 of the first row of temperature control mechanisms 405 and the first temperature control frame 408 of the second row of temperature control mechanisms 405; or the arrangement of a double-headed cylinder between the two rows of temperature control mechanisms 405 can also achieve the opening function of the two rows of temperature control mechanisms 405. This is the case when the temperature control mechanisms 405 are arranged in pairs. Of course, the same method can also be used to simultaneously connect three or more rows of temperature control mechanisms through the first and second linkage assemblies, and similarly use two linear drive assemblies to drive each temperature control mechanism 405 to open.

[0049] Optionally, the first linkage assembly includes a first guide link and the second linkage assembly includes a second guide link, the first guide link is used to pass through the second temperature control frame 409 of the first row of temperature control mechanisms 405 and connect the two first temperature control frames 408 of the first row and the second row of temperature control mechanisms 405, and the second guide link is used to pass through the first temperature control frame 408 of the second row of temperature control mechanisms 405 and connect the two second temperature control frames 409 of the first row and the second row of temperature control mechanisms 405.

[0050] It can be understood that the first guide link and the second guide link not only play a connecting role, but also play a guiding function, ensuring that the driving component drives the first temperature adjustment frame 408 and the second temperature adjustment frame 409 to perform a more stable translational movement, and ensuring that the relative position limit grooves on the first temperature adjustment frame 408 and the second temperature adjustment frame 409 do not deviate significantly, thereby ensuring the accuracy of the position of the limit grooves during the movement process, and being able to smoothly combine to form a limit cavity to firmly limit the bottle preform.

[0051] In another embodiment, the temperature control mechanism 405 is provided with multiple rows corresponding to the preform preparation device 200, and the multiple rows of temperature control mechanisms 405 are arranged in pairs. The driving assembly is connected to one of the first temperature control frames 408 in the single pair of temperature control mechanisms 405, and the two first temperature control frames 408 in the single pair of temperature control mechanisms 405 are connected by a first linkage assembly. The first linkage assembly is used to drive the corresponding two first temperature control frames 408 to move synchronously. The second temperature control frame 409 is fixedly provided on the transfer mechanism.

[0052] It is understood that the first temperature control frames 408 between the temperature control mechanisms 405 arranged in pairs are connected by a first linkage assembly. The first linkage assembly includes a first guide rod. By driving one of the first temperature control frames 408 to move through the driving assembly, the temperature control mechanisms 405 in two rows can be simultaneously driven to clamp or release the preforms, thereby achieving more efficient transfer.

[0053] It should be noted that the arranged temperature control mechanisms 405 are not limited to being arranged in pairs. The temperature control mechanisms 405 arranged in multiple rows can adapt to the transportation requirements of bottle preforms with different numbers of arrangements under different working conditions. In this case, it is only necessary to interconnect the first temperature control frames 408 or the second temperature control frames 409 of each row of the temperature control mechanisms 405 through the linkage assembly 415 (the linkage assembly 415 is, for example, a connecting straight rod), and then the cylinder 406 of the driving assembly can drive one of the first temperature control frames 408 or the second temperature control frames 409 to achieve synchronous opening of the temperature control mechanisms 405 in each row.

[0054] Optionally, the drive assembly includes a baffle disposed at the bottom or top of the first temperature control frame 408 and / or the second temperature control frame 409, a baffle disposed in the direction of linear motion of the first temperature control frame 408 and / or the second temperature control frame 409, and a spring connecting the first temperature control frame 408 and the second temperature control frame 409. The baffle is arranged in correspondence with the baffle, and the baffle is inclined or has a sloped surface on one side. When the first temperature control frame 408 and the second temperature control frame 409 move linearly and the baffle contacts the baffle, the inclined baffle or the inclined surface of the baffle slidingly contacts the baffle, pushing the first temperature control frame 408 and / or the second temperature control frame 409 away from each other, allowing the preform to emerge from the limiting cavity. Because the temperature control mechanism 405 reciprocates linearly, when the baffle disengages the baffle, the spring can tighten the first temperature control frame 408 and the second temperature control frame 409 to form a heat preservation cavity. In this way, the first temperature regulating frame 408 and the second temperature regulating frame 409 can be opened without using an active driving device such as a motor or a linear cylinder, which is beneficial to saving energy and reducing costs.

[0055] Preferably, referring to FIG. 6 , a thermal insulation pad and a heating component connected to the thermal insulation pad are provided in the first temperature regulating frame 408 and / or the second temperature regulating frame 409 .

[0056] It is understood that the heating assembly can maintain the overall temperature of the first temperature regulating frame 408 and the second temperature regulating frame 409, so that when the first temperature regulating frame 408 and the second temperature regulating frame 409 clamp and position the preform, the preform temperature is not rapidly transferred through heat conduction, which could cause the preform to cool rapidly and affect the quality of subsequent bottle blowing. It should be noted that the heating assembly can adopt a heating tube 407 or a heating wire, and the heating tube 407 or heating wire can be installed between the thermal insulation pad and the inner wall of the first temperature regulating frame 408 and / or the second temperature regulating frame 409, to ensure that the temperature of the inner wall of the first temperature regulating frame 408 and / or the second temperature regulating frame 409 on the side in contact with the preform remains within an appropriate range.

[0057] Preferably, referring to FIG. 4 , the temperature-adjusting and demoulding device 400 further includes a guide rail 404 for guiding the linear motion of the temperature-adjusting mechanism 405 .

[0058] It should be noted that the transfer mechanism used to drive the temperature control mechanism 405 includes a screw assembly, which includes a servo motor 401, a screw 402, and a mounting plate 403. The temperature control mechanism 405 is slidably mounted on the screw 402 via the mounting plate 403, while the guide rail 404 guides the mounting plate 403. After the preform is injection molded and the mold is opened, the servo motor 401 drives the temperature control mechanism 405 via the screw 402 along the guide rail 404 to enter the preform preparation device 200. The cylinder 406 drives the temperature control mechanism 405 to close and clamp the preform, and then the temperature control mechanism 405 can be removed for transfer.

[0059] According to another aspect of the present invention, a blow molding production line is provided, comprising the aforementioned multi-row continuous injection molding equipment. The blow molding production line further comprises a blow molding unit 600, a filling unit 700, a sealing unit 800, and a preform transfer unit 900, connected in sequence. The blow molding unit 600 is connected to the preform preparation unit 200. Each of these units is supported and mounted on a frame, which includes a protective cover to protect each unit (the plasticizing and injection unit 100 may optionally be located outside the protective cover) and create a safe, contaminant-free production environment. It will be appreciated that the blow molding production line of the present invention is an all-in-one injection-blowing-filling-sealing machine, offering a higher level of integration. Furthermore, the units are arranged in a linear configuration. Compared to currently available one-step bottle production processes, which typically use a disc-like structure and struggle to increase production by increasing the number of cavities, the present invention employs a linear layout, which is not limited to this. The number of cavities can be increased linearly, and the number of cavities can be multiplied by adding rows.

[0060] It should be noted, referring to Figure 2, that if the transfer time is long, a transfer station 300 can be installed between the preform preparation unit 200 and the bottle blowing unit 600 to provide additional heat treatment for the preforms. Alternatively, a pre-blowing unit 500 can be installed before the bottle blowing unit 600. Furthermore, the bottle blowing unit 600 and the temperature-controlled ejection unit 400 are longitudinally coplanar, enabling the temperature-controlled ejection unit 400 to transfer the preforms to the bottle blowing unit 600 along a one-dimensional straight line. This significantly shortens the traditional multi-dimensional transfer route, allowing for quick and efficient transfer.
