[0060] In this embodiment, according to Figure 1The overall structure diagram of a balloon forming and cutting device is shown in FIG. 1 , wherein the balloon forming mechanism 2 includes:

[0061] A first guide rail plate 201 in a "B" shape, on which a first left channel 2011, a first middle channel 2012 and a first right channel 2013 are sequentially constructed from left to right;

[0062] A second guide plate 202 capable of being assembled with the first guide plate 201, the second guide plate 202 having the same shape as the first guide plate 201, also in a "B" shape, and having a second left channel 2021, a second middle channel 2022 and a second right channel 2023 sequentially constructed on the second guide plate 202 from left to right;

[0063] After the first guide plate 201 and the second guide plate 202 are spliced ​​and assembled, the first left channel 2011 and the second left channel 2021 are aligned and combined into the first transmission channel 21, the first right channel 2013 and the second right channel 2023 are aligned and combined into the second transmission channel 22, the first middle channel 2012 and the second middle channel 2022 are aligned and combined into the common channel 23, and multiple left modules 11 circulate in the first left channel 2011, the second left channel 2021 and the common channel 23, and multiple right modules 12 circulate in the first right channel 2013, the second right channel 2023 and the common channel 23.

[0065] In this embodiment, in order to extend the length of the common channel 23 to achieve the efficiency of balloon molding assembly line processing and cutting, the balloon molding mechanism 2 further includes:

[0066] An intermediate guide plate 203 installed between the first guide plate 201 and the second guide plate 202, the intermediate guide plate 203 is used for the path of the first transmission channel 21, the path of the second transmission channel 22 and the path of the common channel 23, and specifically, a third left channel 2031, a third middle channel 2032 and a third right channel (not shown) are sequentially constructed on the intermediate guide plate 203 from left to right;

[0067] After the first guide rail plate 201, the middle guide rail plate 203 and the second guide rail plate 202 are assembled and spliced, the two ends of the third left channel 2031 are respectively connected to the first left channel 2011 and the second left channel 2021, the two ends of the third right channel (not shown) are respectively connected to the first right channel 2013 and the second right channel 2023, and the two ends of the third middle channel 2032 are respectively connected to the first middle channel 2012 and the second middle channel 2022.

[0068] Figure 2 The overall structure diagram of a device integrating balloon forming and cutting is shown in FIG. Figure 2 As shown, the balloon forming mechanism 2 also includes:

[0069] A first guide rail cover plate 211, which is installed above the first guide rail plate 201, and is used to seal the first left channel 2011, the first middle channel 2012, and the first right channel 2013;

[0070] The second guide rail cover plate 212 is installed above the second guide rail plate 202 , and the second guide rail cover plate 212 is used to close the second left channel 2021 , the second middle channel 2022 and the second right channel 2023 .

[0071] The first guide rail cover plate 211 and the second guide rail cover plate 212 are used to provide safety protection for the balloon formed in the balloon forming mechanism 2 to avoid dust and other problems.

[0072] In addition, the balloon forming mechanism 2 further comprises:

[0073] The third guide rail cover plate 213 is installed above the middle guide rail plate 203. The middle guide rail plate 203 is used to partially close the upper part of the third middle channel 2032, thereby partially exposing the upper part of the common channel 23. The cutting mechanism 3 is arranged at the exposed area of ​​the common channel 23, and the cutting mechanism 3 is used to cut the balloon here.

[0074] In this embodiment, an application structure of the cutting device 31 is as follows: Figure 1 and Figure 3 and Figure 4As shown, the cutting device 31 includes: a knife seat assembly 311, the knife seat assembly 311 includes a base 3111 and a connecting seat 3112 movably mounted on the base 3111, a movable cavity 31111 is opened in the base 3111, the connecting seat 3112 is arranged in the movable cavity 31111, and the movable direction of the connecting seat 3112 is constrained by the movable cavity 31111, so that the connecting seat 3112 can move up and down relative to the base 3111 in the movable cavity 31111, and the blade 32 is installed on the connecting seat 3112, so that the blade 32 can realize synchronous movement with the connecting seat 3112;

[0075] and a tool guide rail plate 312, on which a tool holder moving rail 3121 and a blade moving rail 3122 arranged on the periphery of the tool holder moving rail 3121 are constructed;

[0076] The knife seat moving track 3121 and the blade moving track 3122 have the same basic shape, and the only problem is the path length. If the knife seat moving track 3121 is annular, then the blade moving track 3122 is also annular, but the specification of the blade moving track 3122 is larger. After the base 3111 is installed on the blade moving track 3122, the base 3111 can move on the path constrained by the knife seat moving track 3121 and move with the connecting seat 3112 as a whole, thereby synchronizing the movement of the base 3111 and the connecting seat 3112, and the connecting seat 3112 is movably installed on the base 3111. 1, after the connecting seat 3112 is installed on the blade moving track 3122, the connecting seat 3112 changes its position on the base 3111 through the blade moving track 3122 and can move up and down so that the blade 32 extends into the cutting channel to cut and separate the two connected balloons. It can be understood that the moving trajectory of the connecting seat 3112 is determined by the blade moving track 3122, and the storage position of the connecting seat 3112 in the base 3111 is changed by the blade moving track 3122, so that the blade 32 can move synchronously with the connecting seat 3112 to achieve the up and down movement to cut the balloon and provide a basis.

[0077] As a specific structure of the tool guide plate 312, the tool guide plate 312 includes:

[0078] A front guide rail plate 312a, on which a ring-shaped knife seat front rail is disposed, and the blade moving rail 3122 is constructed on the periphery of the knife seat front rail;

[0079] The rear guide rail plate 312 b is opposite to the front guide rail plate 312 a , and a ring-shaped knife seat rear track is arranged on the rear guide rail plate 312 b . The knife seat front track and the knife seat rear track are combined to form the knife seat moving track 3121 .

[0080] The blade moving track 3122 is partially away from the front track of the blade holder and forms an angle transition, which can be understood as a structure of a local position on the blade moving track 3122 that is trapezoidal. When the connecting seat 3112 passes through this position, the position of the connecting seat 3112 relative to the base 3111 changes, driving the blade 32 to move and perform the cutting work. After the connecting seat 3112 passes through this position, the position of the connecting seat 3112 relative to the base 3111 returns to the state at the time of entry, and at this time drives the blade 32 to reset its position.

[0081] It can be seen from this that by providing a plurality of bases 3111 on the tool guide plate 312 and circulating on the tool guide plate 312, continuous cutting of the balloon can be achieved.

[0082] In addition, a blade seat guide wheel 31112 is installed on the base 3111, and the blade seat guide wheel 31112 is used to be installed on the blade seat moving track 3121; a tool guide wheel 31121 is installed on the connecting seat 3112, and the tool guide wheel 31121 is used to be installed on the blade moving track 3122. The blade seat guide wheel 31112 and the tool guide wheel 31121 not only provide the base 3111 and the connecting seat 3112 to be positioned in the corresponding blade seat moving track 3121 and the blade moving track 3122, but also enable the base 3111 and the connecting seat 3112 to move smoothly, so that the continuous cutting of the balloon can be better circulated.

[0083] The cutting device 31 comprises:

[0084] The lifting component 313, the tool guide plate 312 is installed at the driving end of the lifting component 313, and the lifting component 313 is used to enable the tool guide plate 312 to move up and down. The example shown in this embodiment is a mechanism that drives the cutting device 31 to move up and down as a whole by rotating the hand wheel. It has been used in the prior art and will not be described here.

[0085] In this embodiment, Figure 5 FIG. 4 is a schematic diagram showing the structure of an indicating driving mechanism 4 in a device for integrating balloon forming and cutting in this embodiment. Figure 5 As shown, the device also includes:

[0086] The driving mechanism 4 is arranged below the balloon forming mechanism 2, and is used to drive the left module 11 and the right module 12 to move in the common channel 23; wherein the driving mechanism 4 includes:

[0087] A driving motor 41 and a gear transmission group 42 composed of a plurality of meshing gears, wherein the gear transmission group 42 is connected to the driving end of the driving motor 41; Figure 6 The schematic diagram of the structure of the left module in the device for forming and cutting a balloon is shown. Figure 5 and Figure 6 As shown, a tooth structure 2222 is constructed on the lower side of the left module 11 and the right module 12. The left module 11 and the right module 12 are engaged with the gear transmission group 42 through the tooth structure 2222, so that the left module 11 and the right module 12 can be driven to move by the driving motor 41, thereby enabling multiple left modules 11 and multiple right modules 12 to achieve circular movement in the corresponding first transmission channel 21, the common channel 23 and the second transmission channel 22 to provide power support.
