The second end of the crank rod 302 is provided with the pulley 304, and the pulley 304 extends into the sliding groove 303. When it is necessary to drive the top sealing module 200 to slide horizontally, the driving motor 301 needs to be driven to rotate in the first circumferential direction, so as to drive the second end of the crank rod 302 to swing towards the direction close to the medicine bag. The pulley 304 arranged in the sliding groove 303 drives the top sealing module 200 to slide horizontally towards the direction close to the medicine bag, so as to realize the effect that the opening of the medicine bag extends into the top sealing gap of the top sealing module 200, and the opening of the medicine bag is closed at the top. Meanwhile, the pulley 304 extending into the sliding groove 303 relatively moves upwards along the sliding groove 303, so as to reduce the jamming between the pulley 304 and the sliding groove 303 by using the sliding between the pulley 304 and the sliding groove 303, and the transmission efficiency of the crank slider transmission mechanism is improved, and the sliding difficulty of the top sealing module 200 is effectively reduced. In addition, after the top sealing action is completed, the top sealing module 200 needs to be driven to slide reversely, so as to stagger the top sealing module 200 and the medicine bag.

[0060] In the embodiment of the utility model, the specific working principle of top sealing equipment is as follows:

[0061] Step S1. Top sealing module 200 is in the contraction setting position, and the driving side assembly 202 and passive side assembly 203 of top sealing module 200 are not extended outward to the bag opening above, and the bag opening of heat sealing sealing bag is pushed to the working setting position of top sealing module 200,

[0062] Step S2. The motor 301 is driven to work, the motor output shaft of the motor 301 rotates around the first direction, drives the crank rod 302 to rotate in the first direction, the swing end of the crank rod 302 swings outward, the swing end of the crank rod 302 is provided with a pulley 304, and the sliding groove 303 provided on the sliding bottom plate 201 of the top sealing module 200, the pulley 304 extends into the sliding groove 303, and since the pulley 304 can only slide upward and downward relative to the sliding groove 303, the top sealing module 200 is driven by the crank rod 302 to slide outward horizontally out of the cover body 101;

[0063] Step S3. Until the sensor 307 corresponding to the set position of the cover body 101 detects the detected part 308 on the sliding bottom plate 201 of the top sealing module 200, it is determined that the top sealing module 200 slides horizontally to the working set position, and then the motor 301 stops working;

[0064] Meanwhile, in steps S2 and S3, during the movement of the top sealing module 200 to the working set position, the gap between the active side assembly 202 and the passive side assembly 203 is opened towards the bag top, and the bag top is clamped in the gap through the opening; optionally, in steps S2 and S3, during the sliding of the active side assembly 202 and the passive side assembly 203 to the bag top, the top sealing bag guiding structure 2025 of the active side assembly 202 can be used to guide the bag top, so that the bag opening can smoothly slide into the gap between the active side assembly 202 and the passive side assembly 203;

[0065] Step S4. When the top sealing module 200 is in the working set position, the bag top is between the active side assembly 202 and the passive side assembly 203;

[0066] Step S5. The motor module 204 provided on the top sealing module 200 starts to work, the output end of the motor module 204 drives the rack 2051 to move horizontally to one side through the gear 2052, and the passive side assembly 203 is driven by the rack 2051 to move synchronously towards the passive side assembly 203;

[0067] In addition, in steps S1 to S9, during the horizontal extension and retraction movement of the entire top sealing module 200, the heating pipe 2023 on the top sealing module 200 is always in an open state, the heating pipe 2023 heats the top sealing mold 2022, and the temperature sensor 2026 is used to detect the temperature of the top sealing mold 2022 during the heating process, so as to stop the heating pipe 2023 from working when the temperature is greater than the highest set temperature, and start the heating pipe 2023 to work when the temperature is less than the lowest set temperature, so as to prevent overheating and overcooling protection;

[0068] Step S6. Until the generation of the in-place signal; the triggering process of the in-place signal can be as follows: the detection signal emitted by the probe of the clamping detection sensor 207 installed on the passive side assembly 203 is reflected by the detected structure 208 installed on the active side assembly 202, and the in-place signal is triggered after receiving the reflected signal, then the active side assembly 202 moves to the clamping position and contacts the passive side assembly 203, and the in-place signal is generated; or, the motor module 204 is a step motor that can be measured, so that when the working steps of the step motor reach the set value, i.e., the rack moves to the set number of teeth, the in-place signal is generated; when the in-place signal is generated, it is determined that the bag opening is clamped between the top sealing die 2022 of the active side assembly 202 and the heat sealing distance adjusting plate 2032; in the above clamping process, the top opening of the bag is heat sealed by the heated top sealing die 2022 to achieve the purpose of closing the top opening of the bag;

[0069] Step S7. After the active side assembly 202 and the passive side assembly 203 are clamped to generate the in-place signal, the motor module 204 works in reverse, the output end of the motor module 204 drives the rack 2051 to move horizontally to the opposite side through the gear 2052, and the passive side assembly 203 is driven by the rack 2051 to move synchronously away from the passive side assembly 203 until the reset in-place signal is generated; the generation process of the reset in-place signal is as follows: the detection signal emitted by the probe of the clamping detection sensor 207 installed on the passive side assembly 203 is no longer reflected by the detected structure 208 installed on the active side assembly 202, and the reset in-place signal is generated; or, the motor module 204 is a step motor that can be measured, so that when the working steps of the step motor reach the set value, i.e., the rack moves to the set number of teeth, the reset in-place signal is generated; when the reset in-place signal is generated, it is determined that the top sealing die 2022 of the active side assembly 202 and the heat sealing distance adjusting plate 2032 are separated, and then the top sealing die 2022 of the active side assembly is reset to the initial set position, so that the bag opening is separated from the active side assembly 202 and the passive side assembly 203, and the motor module 204 stops working;

[0070] Step S8. The driving motor 301 works in reverse, the motor output shaft of the driving motor 301 rotates in the second direction, drives the crank rod 302 to rotate in the second direction, the swinging end of the crank rod 302 swings inward, the pulley 304 arranged on the swinging end of the crank rod 302 extends into the sliding groove 303 arranged on the sliding bottom plate 201 of the top sealing module 200, and the top sealing module 200 is driven by the crank rod 302 to slide horizontally into the cover body 101 because the pulley 304 and the sliding groove 303 can only slide upward and downward relative to each other;

[0071] Step S9. Until the cover 101 is contracted to the set position corresponding to the sensor 307 detects the detected part 308 on the sliding bottom plate 201 of the top sealing module 200, it is determined that the top sealing module 200 is horizontally slid to the contraction set position, then the driving motor 301 stops working; and after the top sealing module 200 is retracted to the contraction set position, the sealed bag can be transported away by other equipment, and another bag top is pushed to the working set position of the top sealing equipment for subsequent heat sealing treatment of the top sealing module 200.
