A piston assembly 21 for controlling the suction of the finished product is slidably installed inside the metering tube 2, and the piston assembly 21 slides along the axial direction of the metering tube 2. The electronic control module 4 includes a stroke control element 41 arranged on the outside of the metering cylinder 3. A slide seat 6 is slidably installed on the body 1 through a position adjustment assembly 5. The stroke control element 41 is slidably installed on the slide seat 6 through a fine-tuning assembly 7, and the slide seat 6 and the stroke control element 41 both slide along the sliding direction of the piston assembly 21.

[0022] In this embodiment, the stroke control element 41 adopts a magnetic switch. The structure of the magnetic switch and the connection principle with the metering cylinder 3 and the electronic control module 4 constitute the prior art and are well known to ordinary technicians in this field, so they will not be repeated here.

[0023] In this embodiment, the setting of the electronic control module 4 realizes automatic and precise control of the metering quality.

[0024] Compared with the manual adjustment structure of traditional filling machines, the utility model adopts a coordinated control method of automatic precise control and manual auxiliary adjustment, which solves the problem that the manual adjustment error is large and the error is not easy to be found, thereby avoiding the high defective rate of the finished filling products due to excessive errors, and also avoiding the waste of finished products due to defective finished products.

[0025] like Figure 2 As shown in the figure, a hopper 12, a switch rotary valve 13 and a filling pipe 14 are installed on the machine body 1, the feed end of the switch rotary valve 13 is connected to the discharge port of the hopper 12, one discharge end of the switch rotary valve 13 is connected to the feed end of the metering tube 2, and the other discharge end of the switch rotary valve 13 is connected to the filling pipe 14.

[0026] The process of filling using the utility model is as follows:

[0027] In the first step, the position of the stroke control element 41 is precisely regulated by the electronic control module 4, the position adjustment component 5 and the fine adjustment component 7, so that the metering quality of the metering tube 2 is consistent with the preset filling quality.

[0028] In the second step, the discharge port of the hopper 12 is connected to the feed end of the metering tube 2 by switching the rotary valve 13, and the telescopic rod of the metering cylinder 3 is retracted inward, driving the piston assembly 21 to move.

[0029] In the third step, the space at the feed end of the metering tube 2 is continuously enlarged, and suction is generated in the metering tube 2 to suck the finished product in the hopper 12 into the metering tube 2.

[0030] In the fourth step, when the magnet (not shown) in the inner cavity of the metering cylinder 3 coincides with the stroke control element 41, the stroke control element 41 is acted upon by the magnet to control the metering cylinder 3 to stop, thereby completing the metering action.

[0031] The fifth step is to connect the discharge port of the hopper 12 with the filling tube 14 through the switch valve 13, the telescopic rod of the metering cylinder 3 extends outward, and the piston assembly 21 pushes the finished product to move outward, so that the finished product in the metering tube 2 is filled into the packaging bag through the filling tube 14, completing the filling action.

[0032] like Figure 1 As shown, the electronic control module 4 includes a display 42 and a processor 43. A displacement sensor 44 for monitoring the sliding distance of the piston assembly 21 is also provided inside the metering tube 2. The display 42, the displacement sensor 44, the metering cylinder 3 and the stroke control element 41 are all electrically connected to the processor 43, and the stroke control element 41 is electrically connected to the metering cylinder 3.

[0033] In this embodiment, the processor 43 may be a Siemens S7-1200 PLC controller, the display 42 may be a Mitsubishi GT1565-VTBD touch screen display, and the displacement sensor 44 may be a resistive pull rod displacement sensor.

[0034] In this embodiment, a material storage tube 22 and a sliding cavity 23 are provided in the metering tube 2 , and the piston assembly 21 is slidably installed in the material storage tube 22 along the axial direction of the metering tube 2 .

[0035] In this embodiment, the piston assembly 21 includes a piston and a piston rod. The outer peripheral wall of the piston is tightly attached to the inner wall of the storage tube 22. One end of the piston rod is fixedly connected to the piston, and the other end of the piston rod extends into the sliding cavity 23.

[0036] In this embodiment, a sliding plate 24 is fixed to one end of the piston rod extending into the sliding cavity 23 , one end of the displacement sensor 44 is fixed to the sliding plate 24 , and the other end of the displacement sensor 44 is fixed to the inner wall of the sliding cavity 23 .

[0037] In this embodiment, the setting of the displacement sensor 44 can accurately detect the displacement of the piston assembly 21. Once the displacement of the piston assembly 21 deviates, it can be immediately transmitted to the display 42 for display, and the technician can immediately make adjustments, thereby avoiding the occurrence of a large number of defective filled products due to long-term deviations, thereby avoiding the waste of finished products due to a large number of defective filled products.

[0038] In this embodiment, the cylinder body of the metering cylinder 3 is fixed on the machine body 1, the stroke control element 41 is arranged outside the cylinder body, and the telescopic rod of the metering cylinder 3 extends into the sliding cavity 23 and is fixedly connected to the piston rod.

[0039] Among them, the position adjustment component 5 includes an automatic adjusting screw 51, which extends along the sliding direction of the stroke control element 41. The slide seat 6 is slidably installed on the automatic adjusting screw 51 in a threaded connection manner. A fixed seat 11 is fixed on the body 1, and a servo motor 52 is fixedly installed at one end of the fixed seat 11. The motor shaft of the servo motor 52 is transmission-connected to one end of the automatic adjusting screw 51, and the other end of the automatic adjusting screw 51 is connected to an encoder 53, which is fixedly installed at the other end of the fixed seat 11. The servo motor 52 and the encoder 53 are electrically connected to the processor 43.

[0040] In this embodiment, the encoder 53 may be an Omron incremental encoder of model E6B2-CWZ6C.

[0041] In this embodiment, the automatic adjusting screw 51 and the slide seat 6 form a screw nut structure, and its internal structure and principle are prior art and will not be described in detail here.

[0042] Moreover, the fine-tuning assembly 7 includes a fine-tuning screw 71, which extends along the sliding direction of the stroke control element 41. A nut seat 72 is slidably mounted on the fine-tuning screw 71 in a threaded connection manner, and the stroke control element 41 is fixedly mounted on the nut seat 72.

[0043] A fine-tuning knob 73 is fixedly mounted on the end of the fixing seat 11 . The fine-tuning knob 73 is coaxially arranged with the fine-tuning lead screw 71 . A telescopic rod 74 is fixedly connected between the fine-tuning knob 73 and the lead screw 71 .

[0044] In this embodiment, the pitch of the fine-tuning screw 71 is smaller than the pitch of the automatic adjusting screw 51 .

[0045] In this embodiment, the fine-tuning screw 71 and the nut seat 72 constitute a screw-nut structure, and its internal structure and principle are prior art and will not be described in detail here.

[0046] In this embodiment, the fine-tuning component 7 is a manual auxiliary regulating component. Only when the metering quality after automatic regulation is inconsistent with the preset filling quality, the fine-tuning component 7 will be used for manual fine-tuning.

[0047] In addition, a scale 8 is provided on the metering cylinder 3 , and the scale 8 extends along the sliding direction of the stroke control element 41 . A pointer 9 is fixed to the upper end of the nut seat 72 , and the position of the pointer 9 matches the position of the scale 8 .

[0048] In this embodiment, the provision of the scale 8 and the pointer 9 facilitates the technician to penetrate the position of the stroke control element 41 , and also facilitates the technician to operate the fine-tuning component 7 .

[0049] The method of using the utility model is as follows:

[0050] In the first step, the technician sets the filling mass on the display 42 and presses the adjustment button (not shown in the figure). The processor 43 calculates and processes the set filling mass, and obtains the direction of the servo motor 52 and the number of rotations required based on the detection data of the displacement sensor 44 at this time, the pitch of the automatic adjustment screw 51 and other data.

[0051] In the second step, the processor 43 controls the servo motor 52 to start, and the servo motor 52 drives the automatic adjustment screw 51 to rotate, so that the slide 6 moves axially on the automatic adjustment screw 51. At the same time, the encoder 53 monitors the number of rotations of the automatic adjustment screw 51.

[0052] In the third step, when the number of rotations of the automatic adjustment screw 51 reaches a predetermined value, the encoder 53 sends a stop signal to the processor 43, and the processor 43 controls the servo motor 52 to stop after receiving the stop signal.

[0053] In the fourth step, the displacement data detected by the displacement sensor 44 is transmitted to the processor 43. The processor 43 performs calculations based on the received data to obtain the metering mass at this time, and compares it with the preset filling mass. The obtained data and the comparison results are displayed on the display 42.

[0054] Step 5: If the technician observes that the measured quality is the same as the preset filling quality, the filling machine can be controlled to start filling;

[0055] If the technician observes that the metering quality deviates from the preset filling quality, he / she can operate the fine adjustment component 7 to fine-tune the position of the stroke control element 41 .

[0056] The method for manually assisting the control of the stroke control element 41 is as follows:

[0057] In the first step, the processor 43 calculates the number of revolutions required for manual auxiliary control according to the deviation between the measured mass and the preset filling mass, and transmits it to the display 42 for display.

[0058] In the second step, the technician rotates the fine-tuning knob 73 according to the data displayed on the display 42. The fine-tuning knob 73 drives the fine-tuning screw 71 to rotate synchronously through the power transmission of the telescopic rod 74. The rotation of the fine-tuning screw 71 drives the nut seat 72 and the stroke control element 41 to move, thereby realizing fine-tuning of the position of the stroke control element 41.

[0059] In the third step, after completing the micro-adjustment, the technician can operate on the display 42 to control the displacement sensor 44 to perform another test to ensure that the metering quality is consistent with the preset filling metering.
