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

[0003] There are two production processes for plastic bottles: a two-step method (more commonly used in the early stages of industry development) and a one-step method. In recent years, the one-step method has been increasingly recognized by the market. For example, a Chinese patent with patent application number 202210194038.1 discloses a linear injection-blow-fill-seal integrated plastic bottle packaging equipment with high integration and high energy-saving effects.

[0004] However, in actual application, it was found that the production capacity of the above equipment was difficult to further increase. The main problem was that the bottle preforms could not be quickly transported, and the preform preheating took too much time: because the transfer route between the bottle preforms and the pre-blowing process was very long (after the bottle preforms were taken out by the robot, they needed to be offset, then lowered, and then transferred horizontally), resulting in a long exposure time for the bottle preforms and a lot of heat loss, so it took a long time to replenish the heat. This link consumed too much time and seriously affected the production capacity. Utility Model Content

DETAILED DESCRIPTION

[0029] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0030] Please refer to the attached drawing, which is a structural schematic diagram of a preferred embodiment of a rapid transfer device and a bottle blowing production line provided by the utility model.

[0031] A rapid transfer device is used to transfer preforms of plastic bottles. The rapid transfer device includes a temperature regulating and demolding device 400. The temperature regulating and demolding 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 is used to clamp and heat the preform and transfer the preform to the next process along a linear motion.

[0032] The utility model realizes that the preform delivery and transportation process is completely carried out in a straight line through the temperature-adjusting demolding device 400, selects the optimal horizontal straight line motion, avoids the deviation or turning route that causes the preform to be exposed to the air for too long and lose too much heat, greatly improves the efficiency of transportation, avoids the additional heat supplementation process, and further improves the production capacity; at the same time, the temperature-adjusting mechanism 045 of the temperature-adjusting demolding device 400 can also heat the preform during the straight-line transportation of the preform, ensures that the temperature of the preform is within an appropriate range, and is beneficial to the quality of subsequent bottle blowing.

[0033] It should be noted that the utility model can generally effectively shorten the exposure time of the preform from being ejected to pre-blowing or blowing the bottle. The preform is output in the same direction as the injection molding and is transferred in a straight line, so that the preform is not deviated left or right or up or down during transportation. This can minimize the transmission time. The shorter the time the preform is exposed to the air, the more conducive it is to blowing the bottle.

[0034] Preferably, please refer to Figure 4 As shown, the temperature control mechanism 405 includes a first temperature control frame 408 and a second temperature control frame 409 which are arranged opposite to each other, and a driving component for driving the first temperature control frame 408 and the second temperature control frame 409 to move closer to each other or away from each other. The first temperature control frame 408 and the second temperature control frame 409 are used to clamp and fix the preform to each other.

[0035] It can be understood that the temperature regulating mechanism 405 can be driven by the transfer mechanism to perform linear motion, and the first temperature regulating frame 408 and the second temperature regulating frame 409 of the temperature regulating mechanism can be relatively displaced to achieve a state similar to opening and closing, and the bottle preform can be clamped or released. Therefore, the bottle preform is exposed in the open state, which is convenient for the bottle preform to be quickly taken out by the robot and transferred to the next process in a straight line, without the need to first clamp the bottle preform to rise, then deflect and translate, and finally move down to place the bottle preform when taking the bottle. In this way, a large amount of displacement distance can be reduced and the exposure time of the bottle preform can be shortened.

[0036] It should be noted that the first temperature adjustment frame 408 and the second temperature adjustment frame 409 can be turned on to facilitate the linear transfer of the preform in one-dimensional direction, so as to achieve the optimal route of transfer and reduce the exposure time. In this preferred embodiment, after the mold of the preform preparation device 200 is opened, the preform product directly falls into the temperature adjustment mechanism 405, and then the linear motion is performed to complete the transfer.

[0037] Preferably, please refer to Figure 4 and Figure 5 As shown, a plurality of limiting grooves are spaced apart 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, which are adapted to the preform and used to clamp and fix the preform.

[0038] It can be understood that the first temperature adjustment frame 408 and the second temperature adjustment frame 409 are provided with corresponding limiting grooves, and the limiting grooves on both sides are combined to form a limiting cavity to carry and limit the preform, and the first temperature adjustment frame 408 and the second temperature adjustment frame 409 can be relatively displaced to achieve a similar opening effect so that the preform is no longer limited to facilitate the rapid removal and transfer of the preform. Due to the linear motion mode and the openable function of the temperature adjustment mechanism 405, it is ensured that the preform does not need to go through the steps of taking the preform up, moving horizontally, and then moving downward when the preform is transported linearly, and the vertical displacement route is cancelled. Only the fastest translation movement is required to complete the transportation, which effectively shortens the transportation distance and transportation time.

[0039] In another embodiment of the present invention, a plurality of clamping plates are disposed on opposite side walls of the first temperature regulating frame 408 and the second temperature regulating frame 409, and the clamping plates on the first temperature regulating frame 408 and the second temperature regulating frame 409 are combined in a one-to-one correspondence to form a plurality of limiting cavities, and the limiting cavities are adapted to the bottle preform and are used to clamp and fix the bottle preform.

[0040] Specifically, the clamping plate is an arc-shaped plate structure, and the convex side of the clamping plate is connected to the side wall of the first temperature adjustment frame 408 or the second temperature adjustment frame 409 through a spring.

[0041] It is understandable that the arc-shaped clamping plates on the first temperature adjustment frame 408 and the second temperature adjustment frame 409 can also form a limiting cavity adapted to the bottle preform, and the bottle preform can be clamped or loosened through the limiting cavity. The clamping plates are installed by springs, and the springs can also play a buffering role on the clamping plates, reducing the excessive impact of the clamping plates on the bottle preforms during the process of clamping the bottle preforms, and avoiding damage to the bottle preforms caused by the deviation of the clamping position. In addition, the arc-shaped clamping plates can also meet the clamping requirements of bottle preforms with more diameters, because only part of the arc surface of the clamping plates needs to contact the bottle preforms to achieve the clamping function.

[0042] Preferably, please refer to Figure 4 and Figure 5 As shown, the driving assembly includes a cylinder 406 arranged next to the first temperature adjustment frame 408 and / or the second temperature adjustment frame 409, and the cylinder 406 is used to drive the first temperature adjustment frame 408 and / or the second temperature adjustment frame 409 to move to form the limiting cavity or open the limiting cavity.

[0043] It is understandable that the cylinder 406 can drive the first temperature adjustment frame 408 and / or the second temperature adjustment frame 409 to move, so as to adjust the distance between the first temperature adjustment frame 408 and the second temperature adjustment frame 409. It should be noted that the cylinder can be connected to one of the first temperature adjustment frame 408 and the second temperature adjustment frame 409, or can be connected to both of them at the same time, and can achieve the same combination to form or open the limiting cavity.

[0044] Optionally, the driving assembly includes a baffle plate arranged at the bottom or top of the first temperature regulating frame 408 and / or the second temperature regulating frame 409, a baffle rod arranged in the linear motion direction of the first temperature regulating frame 408 and / or the second temperature regulating frame 409, and a spring connecting the first temperature regulating frame 408 and the second temperature regulating frame 409, the baffle rod is arranged correspondingly to the baffle plate, the baffle plate is arranged obliquely or one side of the baffle plate is an inclined surface, when the first temperature regulating frame 408 and the second temperature regulating frame 409 move along a straight line, when the baffle plate touches the baffle rod, the inclined baffle plate or the inclined surface of the baffle plate pushes the first temperature regulating frame 408 and / or the second temperature regulating frame 409 away from each other during the sliding contact with the baffle rod, so that the preform is exposed from the limiting cavity. Since the temperature regulating mechanism 405 reciprocates along a straight line, when the baffle plate is separated from the baffle rod, the first temperature regulating frame 408 and the second temperature regulating frame 409 can be tightened by the spring 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 active driving devices such as motors or linear cylinders, which is beneficial to saving energy and reducing costs.

[0045] Preferably, a thermal insulation pad and a heating component connected to the thermal insulation pad are provided in the first temperature control frame 408 and / or the second temperature control frame 409, and the heating component includes a heating tube 407 or a heating wire, and the thermal insulation pad is arranged on the inner wall of the first temperature control frame 408 and the second temperature control frame 409, and the heating tube 407 or the heating wire is arranged in the first temperature control frame 408 and the second temperature control frame 409.

[0046] It is understandable that the heating component can maintain the overall temperature of the first temperature regulating frame 408 and the second temperature regulating frame 409, so that the first temperature regulating frame 408 and the second temperature regulating frame 409 will not quickly conduct heat transfer to the temperature of the preform when clamping and limiting the preform, causing the preform to cool down quickly and affecting the quality of subsequent bottle blowing. It should be noted that the heating component can use a heating tube 407 or a heating wire, and the heating tube or heating wire can be arranged between the heat 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 is continuously within an appropriate range.

[0047] Preferably, please refer to Figure 3 As shown, the temperature regulating demoulding device 400 further includes a guide rail 404 for guiding the linear motion of the temperature regulating mechanism 405 .

[0048] Specifically, the transfer mechanism includes a servo motor 401, a screw rod 402 and a mounting plate 403, the temperature control mechanism 405 is mounted on the mounting plate 403, the mounting plate 403 is slidably mounted on the screw rod 402, and the guide rail 404 is used to penetrate the mounting plate 402 and guide the mounting plate 403.

[0049] It can be understood that the transfer mechanism for driving the temperature adjustment mechanism 405 to move includes a servo motor 401, a screw rod 402 and a mounting plate 403. The temperature adjustment mechanism 405 is slidably mounted on the screw rod 402 through the mounting plate 403, and the guide rail 404 guides the mounting plate 403. After the preform is injection molded, the servo motor 401 drives the temperature adjustment mechanism 405 along the guide rail 404 to enter the preform preparation device 200 through the screw rod 402, and the cylinder 406 drives the temperature adjustment mechanism 405 to close and clamp the preform, and then the temperature adjustment mechanism 405 can be moved out for linear transfer of the preform.

[0050] According to another aspect of the utility model, a bottle blowing production line is also provided, which includes the above-mentioned rapid transfer device, and the bottle blowing production line also includes a plasticizing injection device 100, a bottle embryo preparation device 200, a bottle blowing device 600, a filling device 700, a sealing device 800 and a bottle embryo transmission device 900 connected in sequence, and the bottle embryo preparation device 200 and the bottle blowing device 600 are connected through the temperature adjustment mold device 400. It should be noted that the bottle embryo preparation device 200 includes a bottle embryo mold, and the bottle embryo mold and the plasticizing injection device are both existing technologies and will not be repeated here. The above devices are supported and installed by a frame, and the frame includes a protective cover to protect each device to form a safe production environment that is not polluted by the outside world. It can be understood that the bottle blowing production line of the utility model is in the form of an injection, blowing, filling and sealing integrated machine, which is a more integrated equipment, and the various devices are arranged in a linear manner. Compared with the one-step bottle making method currently on the market, which uses a disc structure and it is difficult to increase the output by increasing the number of cavities, the utility model adopts a linear layout and is not limited to this. On the one hand, the number of cavities can be increased in the linear direction, and on the other hand, the number of rows can be increased to double the number of cavities.

[0051] It should be noted that if the handover time is long, a handover station 300 may be provided between the preform preparation device 200 and the bottle blowing device 600 to perform additional heat treatment on the preform; in addition, a pre-blowing device 500 may be provided in front of the bottle blowing device 600. In addition, the bottle blowing device 600 and the temperature-adjusting and demolding device 400 are on the same plane in the longitudinal direction, so that the temperature-adjusting and demolding device 400 can transfer the preform to the bottle blowing device 600 along a one-dimensional straight line, greatly shortening the traditional multi-dimensional motion transfer route, and completing the transfer work quickly and efficiently.

[0052] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0053] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. The above is only the preferred implementation method of the utility model. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the utility model, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without improvement, should be regarded as the protection of the utility model.
