[0039] The application will be described in detail below with reference to the accompanying drawings Figure 1 Figure 6 Some embodiments of the application will be described in detail. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0040] The embodiments of the application provide a storage device 22 for a nozzle bag 7 and a nozzle pressing machine 100, wherein the nozzle bag 7 is formed with a bayonet at the nozzle part, and the storage device for the nozzle bag 7 comprises:

[0041] a rack 1;

[0042] a storage rack 2 comprising a top plate 3, a storage strip 4 and a supporting plate 5 arranged in sequence in the same direction, the top plate 3 being movably connected to the top end of the rack 1, the storage strip 4 being connected between the top plate 3 and the supporting plate 5, the storage strip 4 being provided with a sliding groove 6 penetrating along the length direction thereof, and the nozzle bag 7 being slidably connected with the sliding groove 6, wherein the storage strip 4 is vertically placed, and the supporting plate 5 is used for supporting the nozzle part at the lowermost position in the sliding groove 6;

[0043] a pressing structure 8 for pressing the nozzle part to be connected in the sliding groove 6, so that the nozzle bag 7 is slidably connected with the sliding groove 6.

[0044] ​Specifically, the nozzle bag 7 storage device structure provided by the application is unique, and through the cooperation of the rack 1, the containing rack 2, the pressing structure 8 and the sliding groove 6 and other components, the unstable sliding problem of the nozzle bag 7 during storage can be effectively solved. The containing rack 2 is composed of a top plate 3, a containing strip 4 and a supporting plate 5, the top plate 3 is fixed on the rack 1 through movable connection, the containing strip 4 is connected with the nozzle bag 7 through the sliding groove 6, and it is ensured that the nozzle bag 7 can be stably stored in the sliding groove 6. The pressing structure 8 applies pressure to the nozzle part through the pressing rod 9, so that the nozzle bag 7 is tightly clamped in the sliding groove 6, and the nozzle bag 7 is prevented from sliding out or being unstable. The core advantage of this structure lies in its dynamic stability, which can effectively prevent the nozzle bag 7 from shifting or falling off during the feeding process when the nozzle bag 7 is quickly processed, thereby improving the work efficiency and operation safety. Through the close cooperation of the containing strip 4 and the sliding groove 6 and the precise action of the pressing structure 8, the device not only can ensure the stable storage of the nozzle bag 7, but also can conveniently slide and take when needed. This design greatly improves the storage efficiency on the automatic production line, and is especially suitable for nozzle bag 7 processing in high-frequency and precise operation automatic systems, such as food packaging, pharmaceutical production and other industries.

[0045] Further, the pressing structure 8 comprises a pressing rod 9 and a fixed block 13, one end of the fixed block 13 is fixedly connected with the rack 1, the other end is fixedly connected with the pressing rod 9, the length direction of the containing strip 4 is recorded as a first direction, and the direction perpendicular to the first direction is recorded as a second direction;

[0046] As viewed along the second direction, the pressing rod 9 is located at the upper end of the containing strip 4 and is opposite to the sliding groove 6;

[0047] In the first direction, the pressing rod 9 presses the nozzle part, so that the nozzle part is clamped in the sliding groove and drives the nozzle bag 7 to slide along the direction of the supporting plate 5.

[0048] Specifically, the adjustability of the pressing structure 8 is further increased, so that the pressing rod 9 can be adjusted in position according to the length of different nozzle bags 7. By designing the positioning hole 11, the pressing rod 9 can slide along the length direction of the nozzle of the nozzle bag 7, so that the nozzle bag 7 of different sizes can be properly pressed, and the stability during storage is ensured. The innovation of this design lies in that the adaptability of the device is enhanced, which can support the precise positioning and pressing of nozzle bags 7 of different specifications, effectively preventing the storage instability problem caused by the size mismatch of the nozzle bag 7. By adjusting the position of the pressing rod 9, each nozzle bag 7 can be uniformly and stably pressed during storage, avoiding the loosening or shifting of the nozzle bag 7.

[0049] Further, the pressing structure 8 further comprises a positioning hole 11 formed in the first direction;

[0050] The positioning hole 11 is directly opposite the nozzle part when viewed in the first direction, and the positioning hole 11 allows the pressing rod 9 to slide along the length direction of the nozzle of the nozzle bag 7 to press different lengths of nozzles.

[0051] Specifically, by introducing the design of the positioning hole 11, not only the flexibility of the pressing structure 8 is improved, but also the pressing rod 9 can adapt to different specifications of the nozzle bag 7. This structure allows the pressing rod 9 to be adjusted according to the specific size of the nozzle bag 7, thereby ensuring that each nozzle bag 7 can be properly pressed during storage, further improving the versatility and adaptability of the device. The positioning hole 11 allows the device to adapt to various specifications of the nozzle bag 7, solving the problem that traditional equipment can only handle a single size of the nozzle bag 7.

[0055] Specifically, the Chinese character "fang" sliding groove 6 structure of the accommodating strip 4, the strip body 12 and the fixing piece 10 are connected by clamping, and the Chinese character "fang" design of the sliding groove 6 can effectively form a firm connection with the bayonet of the nozzle bag 7, ensuring that the nozzle bag 7 will not slide out due to external force or vibration. This design optimizes the stability of the storage device through the structure of the Chinese character "fang" sliding groove 6, especially in high-speed operation production lines, it can effectively prevent the nozzle bag 7 from sliding or falling off. The Chinese character "fang" cross section of the sliding groove 6 not only increases the contact area with the bayonet of the nozzle bag 7, but also improves the structural stability of the device, making the fixation of the nozzle bag 7 more secure, avoiding the instability of the traditional clamping plate structure in dynamic operation.

The motor 14 is connected to the top plate 3 through a transmission device, which ensures that the rotation of the top plate 3 can drive the containing strip 4 to make accurate adjustments. This design not only improves the automation level of the equipment, but also reduces the influence of manual operation on the storage stability of the suction nozzle bag 7. The use of the motor 14 enables the device to maintain high precision even at high speed and high frequency, avoiding material misplacement or operation delay caused by improper manual operation. By driving the device through the motor 14, the storage position and movement path of the suction nozzle bag 7 can be accurately controlled, ensuring the stability of each suction nozzle bag 7 during storage and unloading.

[0058] Furthermore, the frame 1 includes a support bearing 15, the top plate 3 is rotationally connected to the support bearing 15, and when viewed in the first direction, the top plate 3 is provided with a turntable 16, the driving end is in transmission connection with the turntable 16, and the driving end can drive the turntable 16 to rotate the containing strip 4 with the top plate 3 around the shaft of the support bearing 15.

[0059] Specifically, the connection of the motor 14 with the support bearing 15 and the turntable 16 further enhances the stability of the entire storage device. Through the rotational connection of the support bearing 15, the top plate 3 can rotate around the shaft, driving the containing strip 4 to move accurately, ensuring that each suction nozzle bag 7 can be stored and accessed at an accurate position. The design of the turntable 16 makes the rotation of the top plate 3 more stable, avoiding instability or operation delay caused by uneven rotation. This structural design is particularly suitable for use on high-speed production lines.

[0060] Furthermore, when viewed in the first direction, at least eight containing strips 4 are evenly arranged around the top plate 3 along the shaft, and the motor 14 is externally connected to a controller, which drives the top plate 3 to rotate regularly around the shaft so that any containing strip 4 is opposite to the pressing structure 8.

[0061] Specifically, the controller drives the operation of the motor 14 to realize the precise rotation and automatic positioning of the top plate 3 and the containing strips 4. The motor 14 is connected to the containing strips 4 through the turntable 16, ensuring that each containing strip 4 can be aligned with the pressing structure 8 as needed. The controller accurately controls the rotation of the top plate 3 according to the needs of the production line, so that the containing strips 4 always remain in the predetermined position, ensuring that the suction nozzle bags 7 can be stored stably and avoiding errors caused by manual adjustment.
