[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] Example 1

[0045] Reference Figures 1-4 The utility model provides an embodiment: a dispensing head that can improve packaging production capacity, including: a support base 1, the support base 1 is used to carry the material to be processed; a lifting mechanism 2, the lifting mechanism 2 is arranged on the support base 1, and a connecting block 211 is provided on the top of the lifting mechanism 2, and a dispensing connector 212 is detachably installed on the connecting block 211, and the lifting mechanism 2 is used to control the lifting and lowering of the dispensing connector 212.

[0046] The lifting mechanism 2 includes: a rectangular block 201, which is fixedly connected to the moving mechanism 3; a lifting drive motor 202, which is fixedly installed in the rectangular block 201; a lifting threaded rod 203, which is fixedly connected to the output end of the lifting drive motor 202; a threaded sleeve 204, one end of which is threadedly connected to one end of the lifting threaded rod 203; an extrusion plate 205, which is fixedly connected to the end of the threaded sleeve 204 away from the lifting threaded rod 203; a telescopic rod 206, The two ends of the telescopic rod 206 are respectively fixed to the rectangular block 201 and the extrusion plate 205, and the telescopic rod 206 is provided with a first telescopic airbag 207; the column 208, the column 208 is fixed to the moving mechanism 3 and is located on one side of the rectangular block 201; the second telescopic airbag 209, the second telescopic airbag 209 is arranged in the column 208, and the second telescopic airbag 209 is communicated with the first telescopic airbag 207; the lifting column 210, the lifting column 210 slides in the column 208, and the bottom of the lifting column 210 is fixed to the top of the second telescopic airbag 209.

[0047] Specifically, the lifting drive motor 202 is started, driving the lifting threaded rod 203 to rotate, and the threaded sleeve 204 is threadedly connected to the lifting threaded rod 203. Therefore, the rotation of the lifting threaded rod 203 causes the threaded sleeve 204 to move up and down along the direction of the lifting threaded rod 203. The extrusion plate 205 is fixedly connected to the end of the threaded sleeve 204 away from the lifting threaded rod 203. Therefore, the extrusion plate 205 will also rise and fall with the rise and fall of the threaded sleeve 204. The telescopic rod 206 plays a guiding role. The first telescopic airbag 207 will be inflated and deflated with the rise and fall of the extrusion plate 205. In addition, the second telescopic airbag 207 in the column 208 09 is connected to the first telescopic airbag 207. When the first telescopic airbag 207 is inflated or deflated, the second telescopic airbag 209 will also be inflated or deflated accordingly. The lifting column 210 slides in the column 208, and its bottom is fixedly connected to the top of the second telescopic airbag 209. Therefore, as the second telescopic airbag 209 is inflated or deflated, the lifting column 210 will also move up and down in the column 208. Since the top of the lifting column 210 is fixedly connected to the connecting block 211, the connecting block 211 and the glue dispensing connector 212 installed thereon will also rise and fall with the lifting of the lifting column 210, thereby realizing the up and down movement of the glue dispensing connector 212.

[0048] Example 2:

[0049] On the basis of Example 1, in order to further improve the adjustment ability of the device, the moving mechanism 3 includes: a moving drive motor 301, the moving drive motor 301 is fixedly installed in the support seat 1; a moving threaded rod 302, the moving threaded rod 302 rotates in the support seat 1, and one end of the moving threaded rod 302 is fixedly connected to the output end of the moving drive motor 301; a guide rod 303, the guide rod 303 is fixed on the support seat 1; a threaded block 304, the threaded block 304 is threadedly connected to the moving threaded rod 302, and slides on the guide rod 303, and the rectangular block 201 and the column 208 are both fixedly connected to the top of the threaded block 304.

[0050] Specifically, the mobile drive motor 301 is started, driving the mobile threaded rod 302 to rotate in the support base 1. The threaded block 304 is threadedly connected to the mobile threaded rod 302. Therefore, under the rotation of the mobile threaded rod 302, the threaded block 304 will move left and right along the direction of the guide rod 303. Since the rectangular block 201 and the column 208 are fixed to the top of the threaded block 304, the entire lifting mechanism 2 will also move with the movement of the threaded block 304, thereby realizing the left and right movement of the dispensing connector 212.

[0051] Among them, multiple groups of glue dispensing needles 2121 extending downward are provided at the bottom of the glue dispensing connector 212, and the multiple groups of glue dispensing needles 2121 are arranged in a matrix to ensure that the glue can evenly cover the area that needs to be packaged.

[0052] Among them, a flow control unit is also provided in the glue dispensing connector 212. The flow control unit is integrated with a high-precision flow valve and a pressure sensor to monitor and adjust the glue flow in real time.

[0053] Among them, a flow control unit is also provided in the glue dispensing connector 212. The flow control unit is integrated with a high-precision flow valve and a pressure sensor to monitor and adjust the glue flow in real time.

[0054] Among them, a control box 101 is also provided on one side of the support seat 1, and a controller is provided in the control box 101. A display screen and a control switch are provided on the control box 101. The display screen and the control switch are electrically connected to the controller respectively, and the controller is electrically connected to the lifting drive motor 202, the moving drive motor 301 and the flow control unit respectively.

[0055] The top of the lifting column 210 is fixedly connected to the connecting block 211 .

[0056] Specifically, after the glue dispensing connector 212 moves to the specified position, the flow control unit starts working, and the high-precision flow valve adjusts the flow of glue according to the instructions of the controller to ensure that the glue can flow out at the set speed. At the same time, the pressure sensor monitors the pressure of the glue in real time to ensure that the flow of the glue is stable and uniform. The bottom of the glue dispensing connector 212 is provided with multiple groups of downwardly extending glue dispensing needles 2121, and the multiple groups of glue dispensing needles 2121 are arranged in a matrix to ensure that the glue can evenly cover the area that needs to be packaged.

[0057] Working principle: Start the lifting drive motor 202, and drive the threaded sleeve 204 and the extrusion plate 205 to rise and fall along the lifting threaded rod 203 through the threaded connection. At the same time, the telescopic airbag system (including the first and second telescopic airbags 209) is inflated and deflated as the extrusion plate 205 moves, thereby driving the lifting column 210 and the dispensing connector 212 on the connecting block 211 to move up and down. At the same time, the mobile drive motor 301 drives the moving threaded rod 302 to rotate, so that the threaded block 304 and the entire lifting mechanism 2 move left and right along the guide rod 303 to achieve lateral positioning of the dispensing connector 212. After reaching the specified position, the flow control unit adjusts the glue flow and pressure according to the controller instructions, and evenly applies glue to the area to be packaged through the matrix-arranged dispensing needles 2121.
