[0031] The application will be further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the application, and not to limit the application. In addition, it should be noted that only the parts related to the application are shown in the drawings for the convenience of description.

[0032] In the description of the application, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0033] In the description of the embodiments, the terms "upper", "lower", "left", "right", "front", "back" and other orientation or position relationships are based on the orientation or position relationship shown in the drawings, which is only for the convenience of description and simplification of operation, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the application. In addition, the terms "first" and "second" are only used to distinguish in the description, and have no special meaning.

[0034] The application discloses an embryo insertion and ejection mechanism of a bottle blowing machine (for the convenience of description, hereinafter referred to as an embryo insertion and ejection mechanism), referring to Figure 1 and Figure 3As shown, the embryo inserting and removing mechanism comprises an upper cam guide rail 100 and a lower cam guide rail 200, a movable roller 300, a sliding assembly 400 and a driving member 500. The upper cam guide rail 100 is movably mounted on a heating frame of the bottle blowing machine along a first direction, and is spaced apart from the lower cam guide rail 200. The upper cam guide rail 100 is provided with two cam portions 101 spaced apart along a second direction. Each cam portion 101 is provided with a descending section, a flat section and an ascending section arranged in sequence along the second direction. The lower cam guide rail 200 is provided with a groove portion 201 corresponding to the cam portion 101. The movable roller 300 is movably mounted between the upper cam guide rail 100 and the lower cam guide rail 200. The sliding assembly 400 is movably mounted on a rotating disc 20 of the bottle blowing machine along the first direction. The sliding assembly 400 is connected with the movable roller 300 and connected with the heating head 10 through a yoke 600. The driving member 500 is connected with the upper cam guide rail 100 and drives the upper cam guide rail 100 to reciprocate between a working position and a standby position. When the upper cam guide rail 100 is in the working position and the rotating disc 20 drives the sliding assembly 400 to rotate, the movable roller 300 can roll between the upper cam guide rail 100 and the lower cam guide rail 200. The cam portion 101 can drive the movable roller 300 to move to drive the sliding assembly 400 to move along the first direction, so that the heating head 10 is inserted into or pulled out of the bottle blank.

[0035] First of all, it should be pointed out that during the actual process of the bottle blowing machine, the bottle blank conveying mechanism conveys the bottle blank to a position corresponding to the embryo inserting and removing mechanism. At this time, the embryo inserting and removing mechanism drives the heating head 10 to descend, so that it is inserted into the bottle blank and the bottle embryo is separated from the bottle blank conveying mechanism. Then the rotating disc 20 drives the bottle embryo on the embryo inserting and removing mechanism to move to a position corresponding to the bottle blank carrying manipulator. After the embryo inserting and removing mechanism pulls out the heating head 10 from the bottle blank, the bottle blank carrying manipulator can carry the bottle blank away. In the prior art, if the bottle embryo conveying mechanism fails to convey the bottle embryo to the correct position, or the bottle blank carrying manipulator is out of synchronization with the movement of the heating head 10, the phenomenon of the heating head 10 hitting the bottle blank or the bottle blank carrying manipulator is likely to occur.

[0036] It can be understood that in the working process of the embryo inserting and dismounting mechanism of the embodiment, the driving member 500 drives the upper cam guide rail 100 to move downward along the first direction, so that the cam portion 101 protrudes out of the warming rack. During the movement of the sliding assembly 400 driven by the rotating disc 20, the movable roller 300 moves between the upper cam guide rail 100 and the lower cam guide rail 200. When the movable roller 300 moves to the first cam portion 101, the movable roller 300 will first descend and then ascend under the drive of the cam portion 101. During the downward movement of the movable roller 300, the sliding assembly 400 descends, so that the warming head 10 descends from the high position and inserts into the bottle embryo. During the upward movement of the movable roller 300, the warming head 10 can pull out the bottle embryo, and the bottle embryo can be carried away by the carrying manipulator. If misalignment occurs between the bottle embryo and the warming head 10 during the embryo inserting process, the driving member 500 drives the upper cam guide rail 100 to move upward along the first direction, so that the cam portion 101 hides in the warming rack. Even if the rotating disc 20 continues to rotate, the warming head 10 will not descend, thereby avoiding the phenomenon that the warming head 10 collides with the bottle embryo. During the embryo dismounting process, if the rotating disc 20 is out of synchronization with the movement of the bottle blank carrying manipulator, the driving member 500 drives the upper cam guide rail 100 to move upward along the first direction, so that the cam portion 101 hides in the warming rack. Even if the rotating disc 20 continues to rotate, the warming head 10 will not descend, thereby avoiding the phenomenon that the bottle embryo collides with the bottle embryo carrying manipulator. Thus, the damage probability of parts when a fault occurs can be reduced, the performance of the bottle blowing machine can be improved, and the waste rate can be reduced.

[0037] It should be noted that due to the cam structure for driving the movable roller 300, the cam structure is split into two parts, i.e., the upper cam guide rail 100 and the lower cam guide rail 200, which has high installation flexibility, high fault tolerance for part processing, and is convenient for docking adjustment. The split cam structure has good accuracy and stability, which is beneficial to improve the reliability of the entire embryo inserting and dismounting mechanism.

[0038] It should be additionally noted that in order to improve work efficiency, the sliding assembly 400 is multiple and is arranged in a circumferential direction of the rotating disc 20.

[0039] Reference Figure 2 and Figure 4As shown, the sliding assembly 400 comprises a sliding block 410, a first sliding rod 420 and a second sliding rod 430, the sliding block 410 is connected with the roller pin shaft 310 of the movable roller 300, the first sliding rod 420 is arranged through the rotating disc 20 and connected with the sliding block 410, one end of the first sliding rod 420 is connected with the shift fork 600, the second sliding rod 430 is arranged in parallel with the first sliding rod 420, the second sliding rod 430 is arranged through the rotating disc 20 and connected with the sliding block 410, and one end of the second sliding rod 430 is connected with the shift fork 600. It can be understood that the first sliding rod 420 and the second sliding rod 430 are arranged to realize the connection of the shift fork 600, the shift fork 600 is used for mounting the warming head 10, the stability and reliability of the double-sliding-rod sliding structure composed of the first sliding rod 420 and the second sliding rod 430 are good, and the warming head 10 can be driven to move up and down synchronously under the driving of the sliding assembly 400 when the movable roller 300 moves up and down under the driving of the cam portion 101.

[0040] Optionally, the first sliding rod 420 is arranged through the sliding block 410 and locked by a connecting bolt 440, and one end of the first sliding rod 420 arranged out of the sliding block 410 is connected with the shift fork 600. The second sliding rod 430 is arranged through the sliding block 410 and locked by a fixing pin 450. It can be understood that the first sliding rod 420 is connected with the sliding block 410 by the connecting bolt 440, and the second sliding rod 430 is connected with the sliding block 410 by the fixing pin 450, the combination of the connecting bolt 440 and the fixing pin 450 can tolerate the machining error of the parts and ensure the accuracy of the relative position of the parts. Further optionally, the second sliding rod 430 is provided with a mounting groove 431, the mounting groove 431 is used for mounting a clamping spring 460, and the clamping spring 460 abuts against the sliding block 410. The clamping spring 460 can further strengthen the connection strength between the sliding block 410 and the second sliding rod 430, resist high-frequency impact force, thereby being beneficial to improving the service life of the sliding assembly 400. It needs to be supplemented that in other embodiments of the present application, the connection mode of the first sliding rod 420 and the second sliding rod 430 with the sliding block 410 can be selected according to actual needs, for example, the first sliding rod 420 and the second sliding rod 430 can be directly connected with the sliding block 410 by welding, or can be connected by a key connection mode, and is not limited to the above limitation.

[0041] Reference Figure 2 and Figure 4As shown, the sliding assembly 400 further comprises an elastic member 470, which is sleeved on the first slide rod 420 away from the shift fork 600, one end of the elastic member 470 is fixedly arranged on the first slide rod 420, and the other end is abutted on the rotating disc 20. It can be understood that when the upper cam rail 100 is in the working position and the rotating disc 20 rotates, the movable roller 300 always moves along the surface of the upper cam rail 100 under the elastic force of the elastic member 470, the tension of the elastic member 470 serves as the upward thrust of the sliding assembly 400 composed of the first slide rod 420 and the second slide rod 430, so that the sliding assembly 400 can quickly move upward during the working process, even can move upward in a cliff-like manner, can be applied to the rising segment curve of the upper cam rail 100 with a larger pressure angle, and is better applied to the bottle blowing machine with high yield. In addition, according to the foregoing description, in the actual working process, the lower cam rail 200 always remains stationary, if the elastic member 470 breaks, the groove part 201 on the stationary lower cam rail 200 can play a protective role to avoid the situation that the shift fork 600 collides with the mandrel of the heating head 10 due to the lack of sufficient upward thrust of the sliding assembly 400. Further, the elastic member 470 is a spring. Of course, in other embodiments of the present application, the elastic member 470 can also select other elastic structural members according to actual needs.

[0042] Optionally, the other end of the first slide rod 420 is connected with an end cover 480, one end of the elastic member 470 is abutted on the end cover 480, and the other end is abutted on the rotating disc 20. Compared with directly fixing one end of the elastic member 470 on the first slide rod 420, in the present embodiment, by arranging the end cover 480 on the first slide rod 420, the twisting phenomenon of the elastic member 470 in the actual working process can be reduced, and the damage probability of the elastic member 470 can be reduced. It should be noted that the end cover 480 can be connected with the first slide rod 420 through screws, fixing pins, buckles or connecting keys, and the specific connection mode of the first slide rod 420 and the end cover 480 is not limited herein.

[0043] Optionally, the first slide rod 420 is provided with the first bearing 30, and the second slide rod 430 is provided with the second bearing 40. It can be understood that, in actual working process, the first slide rod 420 and the second slide rod 430 will move along the first direction relative to the rotating disc 20 under the driving of the movable roller 300, and the first bearing 30 and the second bearing 40 can reduce the sliding friction between the first slide rod 420, the second slide rod 430 and the rotating disc 20, thereby reducing the abrasion of the first slide rod 420, the second slide rod 430 and the rotating disc 20, and being beneficial to prolong the working life of the first slide rod 420, the second slide rod 430 and the rotating disc 20. It should be additionally pointed out that, in the embodiment of the present application, the type and model of the first bearing 30 and the second bearing 40 can be selected according to actual needs, and the specific parameters of the first bearing 30 and the second bearing 40 are not limited herein.

[0044] Referring to Figure 2 and Figure 4 As shown in the figures, the embryo inserting and dismounting mechanism further comprises an upper guide rail 700 and a lower guide rail 800, the lower guide rail 800 is fixed on the warming rack of the bottle blowing machine, the upper guide rail 700 is connected with the lower guide rail 800 through a connecting rod 900, and is arranged in a spaced manner with the lower guide rail 800. The upper cam guide rail 100 is movably installed on the upper guide rail 700, and the lower cam guide rail 200 is fixed on the lower guide rail 800. It can be understood that, by arranging the upper guide rail 700 and the lower guide rail 800, the upper guide rail 700, the connecting rod 900 and the lower guide rail 800 constitute the rack of the entire embryo inserting and dismounting mechanism, in actual assembly process, the embryo inserting and dismounting mechanism can be assembled into a module first, and then is installed on the warming rack of the bottle blowing machine, thereby realizing the modular assembly of the embryo inserting and dismounting mechanism, and being beneficial to the assembly of the entire bottle blowing machine. It should be additionally pointed out that, in the embodiment of the present application, the connection mode of the lower guide rail 800 and the warming rack can be adjusted according to actual needs, and the connection mode of the lower guide rail 800 and the warming rack is not limited herein. The connection mode of the lower guide rail 800 and the upper guide rail 700 with the connecting rod 900 can also be adjusted according to actual needs, and the connection mode of the lower guide rail 800 and the upper guide rail 700 with the connecting rod 900 is not limited herein.

[0045] Optionally, the upper cam guide rail 100 includes a blank insertion upper cam guide rail 110 and a blank removal upper cam guide rail 120, and the blank insertion upper cam guide rail 110 and the blank removal upper cam guide rail 120 are spaced apart along the second direction. The blank insertion upper cam guide rail 110 and the blank removal upper cam guide rail 120 are each provided with a cam part 101. There are two driving members 500, which are respectively provided corresponding to the blank insertion upper cam guide rail 110 and the blank removal upper cam guide rail 120. Understandably, instead of using a single drive unit 500, splitting the upper cam guide rail 100 into two parts—the blank insertion upper cam guide rail 110 and the blank removal upper cam guide rail 120—and having each of these driven by a separate drive unit 500 allows for independent adjustment of their working positions during operation, based on any faults that occur during blank insertion or removal. In other words, if a fault occurs during blank insertion but the blank removal process is normal, the drive unit 500 moves the blank insertion upper cam guide rail 110 to a standby position, which will not affect the normal operation of the blank removal process. Conversely, if a fault occurs during blank removal but the blank insertion process is normal, the drive unit 500 moves the blank removal upper cam guide rail 120 to a standby position, which will also not affect the normal operation of the blank insertion process.

[0046] It should be noted that in this embodiment, both drive components 500 are cylinders. Of course, in other embodiments of the present invention, both drive components 500 may also be motor push rods, or one drive component 500 may be a cylinder and the other may be a motor push rod.

[0047] Optionally, the lower cam guide rail 200 includes a blank insertion lower cam guide rail 210 and a blank removal lower cam guide rail 220, which are spaced apart along a second direction. Each of the blank insertion lower cam guide rail 210 and the blank removal lower cam guide rail 220 is provided with a groove portion 201. It can be understood that when the upper cam guide rail 100 includes a blank insertion upper cam guide rail 110 and a blank removal upper cam guide rail 120, the lower cam guide rail 200 is also divided into a blank insertion lower cam guide rail 210 and a blank removal lower cam guide rail 220, which are respectively corresponding to the blank insertion upper cam guide rail 110 and the blank removal upper cam guide rail 120. This facilitates paired processing during manufacturing; that is, the blank insertion upper cam guide rail 110 and the blank insertion lower cam guide rail 210 are processed as a set of corresponding parts, and the blank removal upper cam guide rail 120 and the blank removal lower cam guide rail 220 are processed as a set of corresponding parts.

[0048] Of course, it should be noted that, as mentioned above, since the lower cam guide rail 200 remains stationary during the process, in an alternative embodiment of the present invention, the lower cam guide rail 200 can be a one-piece structure without being disassembled.

[0049] The advantages of the embryo inserting and discharging mechanism of the embodiment are as follows:

[0050] Firstly, the embryo inserting upper cam guide rail 110 and the embryo discharging upper cam guide rail 120 are in a split structure, and the embryo inserting lower cam guide rail 210 and the embryo discharging lower cam guide rail 220 are in a split structure, which is more flexible, can tolerate the machining error of parts, and is convenient for the butt joint adjustment of various parts.

[0051] Secondly, the split cam guide rail combined with the sliding assembly 400 can meet the precision and stability of the embryo inserting and discharging action under high speed and yield.

[0052] Thirdly, the phenomenon of the collision between the warming head 10 and the bottle embryo when the bottle embryo and the warming head 10 are misaligned in the embryo inserting process is avoided, and the phenomenon of the bottle embryo colliding with the bottle embryo carrying manipulator due to the asynchronous movement of the rotating disc 20 and the bottle embryo carrying manipulator in the embryo discharging process is avoided.

[0053] Fourthly, the lower guide rail 800, the embryo inserting lower cam guide rail 210 and the embryo discharging lower cam guide rail 220 do not participate in the work of the embryo inserting and discharging action, and play a protection and limiting role, which prevents the situation that the shifting fork 600 collides with the mandrel of the warming head 10 when the elastic element 470 is broken and the sliding assembly 400 does not have enough upward thrust.

[0054] Fifthly, the tension of the elastic element 470 serves as the upward thrust of the sliding assembly 400 composed of the first sliding rod 420 and the second sliding rod 430, which can make the sliding assembly 400 quickly move upward in the working process, even can move upward in a cliff-like manner, can adapt to the rising segment curve of the upper cam guide rail 100 with a larger pressure angle, and is better suitable for the blow molding machine with high yield.

[0055] The application further discloses a blow molding machine, which comprises the embryo inserting and discharging mechanism, the rotating disc 20, the bottle blank conveying mechanism and the bottle blank carrying manipulator of the blow molding machine in the foregoing description. The embryo inserting and discharging mechanism of the blow molding machine can insert the warming head 10 into the bottle blank conveyed by the bottle blank conveying mechanism and make the bottle embryo separate from the bottle blank conveying mechanism. The rotating disc 20 can drive the bottle embryo on the embryo inserting and discharging mechanism of the blow molding machine to move to a position corresponding to the bottle blank carrying manipulator. After the embryo inserting and discharging mechanism of the blow molding machine pulls out the warming head 10 from the bottle blank, the bottle blank carrying manipulator can carry the bottle blank away. It can be understood that, due to the embryo inserting and discharging mechanism described in the foregoing description, the phenomenon of the collision between the warming head 10 and the bottle embryo when the bottle embryo and the warming head 10 are misaligned in the embryo inserting process is avoided, and the phenomenon of the bottle embryo colliding with the bottle embryo carrying manipulator due to the asynchronous movement of the rotating disc 20 and the bottle blank carrying manipulator in the embryo discharging process is avoided. The stability and reliability of the blow molding machine are improved, the damage probability of parts when a fault occurs is reduced, and the waste rate can be reduced.
