[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0018] Reference Figures 1-6 This embodiment of the present invention provides a sealing machine for processing erythromycin eye ointment, comprising: The carrying mechanism 100 includes a conveyor belt 101, a support column 102 fixedly installed at the bottom of the conveyor belt 101, and a fixing frame 103 fixedly installed at the top of the conveyor belt 101. The drive mechanism 200 includes a fixed plate 201 fixedly installed on the outer surface of the conveyor belt 101, a first cylinder 202 adapted to be installed on the outer surface of the fixed plate 201, a slide rail 203 fixedly installed on the outer surface of the fixed plate 201, a fixed block 204 fixedly installed on the output end of the first cylinder 202, two guide blocks 205 rotatably connected to the fixed block 204, a clamping assembly 206 for fixing materials, a lifting assembly 207 for controlling the sealing height, and a quick-release assembly 208 for disassembling the mold.

[0019] Specifically, the clamping assembly 206 includes a slide plate 206a rotatably connected to the guide block 205 and slidably engaged with the slide rail 203, a first guide rod 206b rotatably connected to the outer surface of the slide plate 206a, a second guide rod 206c and a third guide rod 206d rotatably connected to both ends of the first guide rod 206b, a clamping plate 206e rotatably connected to the third guide rod 206d, and a positioning pin 206f fixedly connected to the clamping plate 206e and slidably engaged with the fixing plate 201.

[0020] When it is necessary to clamp and fix the erythromycin eye ointment tube, the first cylinder 202 is activated. The first cylinder 202 pushes the fixed block 204 connected to its output end to move in a predetermined direction, causing the two guide blocks 205 to move synchronously. Since the guide blocks 205 are rotatably connected to the fixed block 204 and the slide plate 206a respectively, the slide plate 206a is driven to slide inward along the slide rail 203 to move closer together. During the movement of the slide plate 206a, the first guide rod 206b drives the second guide rod 206c and the third guide rod 206d to move in conjunction, and finally pushes the clamping plate 206e to close towards the center to achieve clamping and fixing of the material. During this process, the positioning pin 206f slides with the fixed plate 201 to play an auxiliary guiding and stable support role, effectively preventing the clamping plate 206e from deviating or jamming during movement, and ensuring that the clamping action is smooth, accurate and reliable.

[0021] Furthermore, the lifting assembly 207 includes a second cylinder 207a adapted to be installed on the top of the fixed frame 103, an adjusting plate 207b fixedly installed on the output end of the second cylinder 207a, a sealing tube 207c disposed at the bottom of the adjusting plate 207b, and a sealing head 207d used in conjunction with the sealing tube 207c.

[0022] When the conveyor belt 101 transports the erythromycin eye ointment tube to the sealing station, the second cylinder 207a is activated. Its output end pushes the adjusting plate 207b to move downward in the vertical direction. The adjusting plate 207b drives the sealing tube 207c and sealing head 207d fixed at its bottom to move downward synchronously, so that the sealing head 207d is pressed against the end of the tube, completing the sealing operation. This structure achieves stable positioning of the sealing height through precise stroke control of the second cylinder 207a. In conjunction with the conveyor belt 101, it can continuously seal materials at multiple stations in sequence, improving production efficiency and automation.

[0023] Furthermore, the quick-release assembly 208 includes a fixing rod 208a fixedly installed on the inner wall of the sealing tube 207c, a button 208b that slides with the inner surface of the sealing head 207d, a limiting block 208c fixedly connected to the button 208b, a spring 208d fixedly connected to the limiting block 208c, and a slider 208e fixedly connected to the other end of the spring 208d and sliding with the fixing rod 208a.

[0024] When it is necessary to replace the sealing head 207d with a different specification, the operator presses the button 208b. After the button 208b is subjected to force, it drives the limiting block 208c, which is fixedly connected to it, to move synchronously and disengage from the limiting groove on the inner wall of the sealing tube 207c. At the same time, the compressed spring 208d stores energy. At this time, the axial locking state between the limiting block 208c and the sealing tube 207c is released, and the sealing head 207d falls naturally along the inner wall of the sealing tube 207c under its own gravity, realizing quick disassembly. When a new sealing head 207d needs to be installed, the slider 208e on the new sealing head 207d is aligned with the fixing rod 208a and pushed axially into the sealing tube 207c. During the pushing process, the inclined surface at the front end of the limiting block 208c contacts the inner wall of the sealing tube 207c and generates radial compression. After the slider 208e is fully in place, the spring 208d releases its stored energy, pushing the limiting block 208c to automatically spring into the limiting groove of the sealing tube 207c, achieving reliable snap-fit ​​and axial fixation.

[0025] Furthermore, the outer surface of the slide rail 203 slides in contact with the outer surface of the slide plate 206a, and the two ends of the guide block 205 are rotatably connected to the fixed block 204 and the slide plate 206a respectively, with bearings provided at the connection points.

[0026] Preferably, the first guide rod 206b is provided with a bearing at the connection between it and the second guide rod 206c and the third guide rod 206d. The end of the second guide rod 206c is rotatably connected to the fixing plate 201 and the connection is provided with a bearing. The outer surface of the positioning pin 206f is in sliding fit with the inner surface of the fixing plate 201.

[0027] It should be noted that the outer surface of the limiting block 208c is slidably inserted into the inner surface of the sealing tube 207c, and the inner surface of the sealing tube 207c is provided with a limiting groove that matches the limiting block 208c. The outer surface of the slider 208e is slidably engaged with the inner surface of the fixing rod 208a.

[0028] In use, the erythromycin eye ointment tubes to be sealed are first placed sequentially on the conveyor belt 101. The conveyor belt 101, driven by a power source, intermittently feeds the tubes, precisely transporting them to the sealing station. Once the tubes reach the designated position, the first cylinder 202 in the drive mechanism 200 is activated. The first cylinder 202 pushes the fixed block 204 connected to its output end to move horizontally, causing the two guide blocks 205 to move synchronously. Since the two ends of the guide block 205 are rotatably connected to the fixed block 204 and the slide plate 206a respectively, and bearings are provided at the connection points, smooth rotational transmission can be achieved. This drives the slide plate 206a to slide inward along the slide rail 203, achieving symmetrical convergence on both sides. During the movement of the slide plate 206a, the first cylinder 202, rotatably connected to its outer surface... A guide rod 206b drives the second guide rod 206c and the third guide rod 206d in a coordinated action. The end of the second guide rod 206c is rotatably connected to the fixed plate 201 and is equipped with a bearing to ensure that the overall linkage mechanism is evenly stressed and runs smoothly. Finally, the third guide rod 206d pushes the clamping plate 206e, which is rotatably connected to it, to close towards the center, thereby clamping and fixing the tail of the erythromycin eye ointment tube. During this process, the positioning pin 206f slides against the inner surface of the fixed plate 201, playing a role in auxiliary guidance and structural stability, effectively preventing the clamping plate 206e from tilting or jamming during movement, and ensuring accurate and reliable clamping action. After clamping is completed, the lifting assembly 207 starts to work, the second cylinder 207a is activated, and its output end pushes the adjusting plate 207. b moves vertically downwards, and the adjusting plate 207b drives the sealing tube 207c and sealing head 207d fixed at its bottom to move downwards simultaneously, so that the sealing head 207d is precisely pressed against the end of the hose, completing the heat sealing or cold pressing sealing operation. This process is controlled by the precise stroke of the second cylinder 207a to achieve stable positioning of the sealing height. With the periodic feeding of the conveyor belt 101, the materials at multiple workstations can be sealed continuously in sequence, significantly improving production efficiency and automation. When it is necessary to change the sealing head 207d of different specifications to adapt to different pipe diameters or sealing processes, the operator only needs to press the button 208b. After the button 208b is subjected to force, it drives the limiting block 208c fixedly connected to it to disengage from the limiting groove on the inner wall of the sealing tube 207c. Simultaneously, the compressed spring 208d stores energy. At this time, the axial locking state between the limiting block 208c and the sealing tube 207c is released. The sealing head 207d falls naturally along the inner wall of the sealing tube 207c under its own gravity, achieving quick disassembly. When installing a new sealing head 207d, align the slider 208e on the new part with the fixing rod 208a and push it axially into the sealing tube 207c. During the pushing process, the inclined surface at the front end of the limiting block 208c contacts the inner wall of the sealing tube 207c and generates radial compression. After the slider 208e is fully in place, the spring 208d releases its stored energy, pushing the limiting block 208c to automatically spring into the limiting groove of the sealing tube 207c, achieving reliable locking and axial fixation. The entire replacement process requires no tools and is simple and quick to operate.

[0029] In summary, by setting up the button-type quick-release component 208, tool-free quick assembly and disassembly of the sealing head 207d can be achieved, effectively shortening mold changeover time, improving equipment changeover efficiency and production continuity. At the same time, the use of linkage and double-guide clamping structure, combined with the stabilizing guiding effect of the positioning pin 206f, ensures smooth clamping action and accurate centering, effectively avoiding hose positioning deviation and nozzle damage, improving clamping accuracy and sealing quality consistency, and ensuring the stability of the production process and product quality.
