When the transmission wheel 620 rotates to a position where the gear teeth are located between the transmitting end 741 and the receiving end 742, the receiving end cannot receive the signal transmitted by the transmitting end due to the blocking of the gear teeth, and therefore, the control board 410 can know the specific stroke of the backward movement of the push rod 310 according to the number of times that the signal cannot be received and fed back by the photoelectric switch 740.
The transmission mechanism 600 drives the push rod 310 to move back and forth through tooth-shaped engagement, and the bottom of the push rod 310 is provided with a plurality of transmission teeth 311 arranged in the back and forth direction. The gear transmission structure further includes a three-pole planetary gear structure (not shown), a transmission shaft 630 and an output wheel 640, the transmission shaft 630 is rotatably disposed in the gear box 610, the transmission wheel 620 and the output wheel 640 are sleeved on the transmission shaft 630, and the teeth of the output wheel 640 are engaged with the transmission teeth 311 at the bottom of the push rod 310.

In this embodiment, the output wheel 640 and the driving wheel 620 are preferably configured as an integral structure, and the transmission ratio of the output wheel 640 and the driving wheel 620 is preferably set to 3: 1.
In order to facilitate the control board 410 to know the forward movement stroke of the push rod 310, a sensing member is disposed at the rear end of the push rod 310, a second sensing switch corresponding to the sensing member and used for assisting in controlling the forward movement stroke of the push rod is disposed in the casing 100, and the second sensing switch is electrically connected to the control board 410.
Specifically, the sensing member preferably employs a magnet 710, and the second sensing switch preferably employs a magnetic induction switch 720. A recess hole for receiving the magnet 710 is formed at the top side of the rear end of the push rod 310, and the magnet 710 is fixed in the recess hole. Because the maximum travel of the push rod 310 moving forwards is different when a hose is mounted on the hose frame 200, two magnetic induction switches 720 are arranged at intervals front and back, and comprise a magnetic induction switch I721 arranged at the back and a magnetic induction switch II 722 arranged at the front. For ease of mounting, two magnetic induction switches are integrally disposed on a substrate 730. The substrate 730 is disposed above the push rod 310 and electrically connected to the control board 410, in order to mount the substrate 730, a boss 140 integrally formed with the casing 100 is disposed on an inner wall of the casing 100, a slot 141 for the edge of the substrate 730 to be inserted into is disposed on the boss 140, and the substrate 730 is fixed in the casing 100 by matching with the slot 141.
When the machine body is in a working state, namely, a rubber tube is arranged on the rubber tube frame 200, the rubber tube has a certain thickness in the front-back direction, and when the push rod 310 moves forwards until the magnet 710 corresponds to the magnetic induction switch I721 up and down, the push rod 310 moves forwards to a limit position. When the machine body is in a non-working state, namely when no rubber tube is mounted on the rubber tube rack 200, the forward stroke of the push rod 310 is increased due to no blocking of the rubber tube, and due to manual operation and the like, when the push rod 310 moves forward until the magnet 710 vertically corresponds to the magnetic induction switch II 722, the push rod 310 moves forward to the limit position.
When the machine body is in a working state, namely when a rubber pipe is installed on the rubber pipe frame 200, the trigger 430 is pressed, the main switch 420 is switched on, the control panel 410 is electrified and supplies power to the motor 500, the motor 500 is electrified to rotate forwards, and the motor shaft drives the push rod 310 to move forwards through the transmission mechanism 600. When the push rod 310 moves forward until the magnet 710 is vertically corresponding to the magnetic induction switch i 721, the control board 410 determines that the push rod 310 has moved forward to the limit position according to the signal fed back by the magnetic induction switch i 721. If the trigger 430 is further pressed, the control panel 410 supplies power to the motor 500 in a reverse direction, the motor 500 rotates in a reverse direction, and the motor shaft drives the push rod 310 to move backward through the transmission mechanism 600. In the backward movement process of the push rod 310, the photoelectric switch 740 feeds back a signal to the control board 410 under the blocking of the gear teeth on the transmission wheel 620, when the number of times that the photoelectric switch 740 is blocked by the gear teeth reaches N1, the control board 410 judges that the push rod 310 has moved backward to the limit position according to the signal fed back by the photoelectric switch 740, the control board 410 stops supplying power to the motor, the motor 500 stops rotating, and the push rod 310 stops moving backward. If the maximum number of times the driving tooth 311 is engaged with the output wheel 640 when the push rod 310 moves from front to rear is 60 times, N1 should be 180 times since the gear ratio between the output wheel 640 and the driving pulley 620 is set to 3: 1.
When the machine body is in a non-working state, namely the rubber tube is not installed on the rubber tube rack 200, when the push rod moves forwards to the position where the magnet corresponds to the magnetic induction switch II 722 up and down, the push rod 310 moves forwards to the limit position. At this time, the trigger 430 is pressed, the control board 410 judges that the push rod 310 has moved forward to the limit position according to the signal fed back by the magnetic induction switch ii 722, if the trigger 430 is continuously pressed, the control board 410 supplies power to the motor 500 in the reverse direction, the motor 500 rotates in the reverse direction, and the motor shaft drives the push rod 310 to move backward through the transmission mechanism 600. In the backward movement process of the push rod 310, the photoelectric switch 740 feeds back a signal to the control board 410 under the blocking of the gear teeth on the transmission wheel 620, when the number of times that the photoelectric switch 740 is blocked by the gear teeth reaches N2, the control board 410 judges that the push rod 310 has moved backward to the limit position according to the signal fed back by the photoelectric switch 740, the control board stops supplying power to the motor, the motor 500 stops rotating, and the push rod 310 stops moving backward. If the interval between the magnetic induction switch i 721 and the magnetic induction switch ii 722 corresponds to the distance of three driving teeth 311, the maximum number of times of engagement of the driving teeth 311 with the output wheel 640 when the push rod 310 moves from front to back is 63, and since the transmission ratio between the output wheel 640 and the driving wheel 620 is set to 3:1, N2 should be 183 times.
If the trigger 430 is released and the push rod 310 is not moved forward to the limit position in the operating state, in order to prevent glue dripping, the control board 410 supplies power to the motor 500 in the reverse direction after the trigger 430 is released, the motor 500 rotates in the reverse direction, and the motor shaft drives the push rod 310 to move backward for a certain distance through the transmission mechanism 600. Assuming that the distance of the push rod 310 moving backwards while preventing glue dripping is the length of one driving tooth 311, since the transmission ratio between the output wheel 640 and the driving wheel 620 is set to 3:1, the number of teeth of the driving wheel 620 rotating in reverse direction should be three, i.e. the photoelectric switch 740 is blocked by the teeth of the driving wheel 620 three times. The control board 410 judges whether the push rod 310 moves backwards to a proper position according to a signal fed back by the photoelectric switch 740, when the photoelectric switch 740 is shielded by the gear teeth of the driving wheel 620 for three times, the push rod 310 moves backwards to a proper position, the control board stops supplying power, the motor 500 stops rotating, and the push rod 310 stops moving backwards.
It is understood that the specific mounting structure of the substrate 730 is not limited to the above description or the drawings, and other reasonable fixing and mounting structures, such as screw fixing, can be adopted.
It is understood that the sensing member and the second inductive switch are not limited to the above-described cooperation of the magnet 710 and the magnetic inductive switch 720, and other reasonable cooperating members may be adopted.
It should be understood that the first inductive switch is not limited to the photoelectric switch 740 described above or shown in the drawings, and other inductive switches capable of detecting the number of teeth rotated by the driving wheel 620 may be used.
It can be understood that the output wheel 640 and the driving wheel 620 may also be a split structure, that is, the output wheel and the driving wheel are separately formed and fixed on the transmission shaft 630.
It will be appreciated that other suitable transmission ratios between the output wheel 640 and the drive wheel 620 may be used. The maximum number of times the driving gear 311 is engaged with the output wheel 640 when the push rod 310 moves from front to back may also be set to other reasonable times depending on the specific length of the push rod. Accordingly, the specific values of N1 and N2 are reasonably determined according to the maximum number of times the push rod is engaged with the output wheel when moving and the transmission ratio between the output wheel 640 and the transmission wheel 620.
In addition to the above preferred embodiments, the present invention has other embodiments, and those skilled in the art can make various changes and modifications according to the present invention without departing from the spirit of the present invention, which should fall within the scope defined by the appended claims.
