[0038] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0039] Example, see Figure 1~Figure 2, which is an embodiment of the utility model, proposes an automatic outer bag removal device for separating the outer bag of the raw material medicine bag 20 from the inner bag, including a conveyor belt 1, a support member 2, a lifting plate 3, and a clamp 4. The conveyor belt 1 is used to convey the raw material medicine bag 20; there are support members 2 on both sides of the conveyor belt 1; the lifting plate 3 is lifted and arranged between the support members 2 on both sides and is located above the conveyor belt 1; the clamp 4 is arranged on the lifting plate 3, and after the clamp 4 is closed, it is used to clamp the outer bag of the raw material medicine bag 20 delivered by the conveyor belt 1.

[0040] In this embodiment, there are support members 2 on both sides of the conveyor belt 1, and the lifting plate 3 can slide up and down between the left and right support members 2. Two left and right clamps 4 are arranged at the lower end of the lifting plate 3. When it is not necessary to remove the outer bag, the lifting plate 3 and the clamps 4 are both at the upper end of the support member 2 to ensure that the raw material medicine bag 20 on the conveyor belt 1 can pass smoothly. When it is necessary to remove the outer bag, the clamps 4 are lowered to the clamping position and are in an open state. After the conveyor belt 1 conveys the raw material medicine bag 20 forward to the clamping area of ​​the clamps 4, the conveyor belt 1 stops running, and the left and right clamps 4 are closed to clamp the front end of the outer bag. Then the lifting plate 3 drives the clamps 4 to rise, and the conveyor belt 1 continues to run. The clamps 4 drive the outer bag of the raw material medicine bag 20 to rise. The operator only needs to cut or disassemble the rear end of the outer bag. In the process of the outer bag rising, the inner bag will be separated from the outer bag by gravity, and as the conveyor belt 1 continues to move forward, the lifting plate 3 and the clamps 4 rise to the initial position and stop running, so that the clamps 4 are opened, and the outer bag can be taken away manually. Mechanized operation saves time and effort. The operator only needs to cut or disassemble the rear end of the outer bag, which can reduce the labor intensity of the operator and improve production efficiency. In order to ensure that the outer bag is reliably clamped, the width of the clamped part of the front end of the outer bag along the front and rear direction is ≥30mm. The conveyor belt 1 can send the inner bag to the next process link to ensure the seamless connection and automated process of the automatic operation line.

[0041] Furthermore, if Figure 1 and Figure 2 As shown, it also includes a connecting cross bar 5, which is located above the lifting plate 3, one end of the connecting cross bar 5 is connected to the support member 2 located on one side of the conveyor belt 1, and the other end of the connecting cross bar 5 is connected to the support member 2 located on the other side of the conveyor belt 1. The upper ends of the left and right support members 2 are connected together by the connecting cross bar 5 to form a door-shaped frame, which has higher overall strength and better stability.

[0042] Furthermore, if Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the rodless cylinder 6 is also included. The rodless cylinder 6 includes a cylinder body and a slider. The cylinder body of the rodless cylinder 6 is arranged on the support 2. The slider of the rodless cylinder 6 is connected to the lifting plate 3. The lifting plate 3 is lifted and lowered by the rodless cylinder 6 and arranged between the supports 2 on both sides. The rodless cylinder 6 is used to drive the lifting plate 3 to rise and fall. The rodless cylinder 6 does not have a traditional piston rod extending out of the cylinder body. Instead, the rodless cylinder 6 converts the linear motion of the piston into the linear motion of the slider through an ingenious mechanical or magnetic connection method, thereby driving the lifting plate 3 to move linearly, which can greatly save space and simplify the mechanical design.

[0043] In order to realize automatic control of the rodless cylinder 6, a photoelectric sensor is arranged on the support 2 on one side of the conveyor belt 1. The output end of the photoelectric sensor is connected to the input end of the controller. The output end of the controller is also electrically connected to the rodless cylinder 6 and the rotating drive mechanism 21 for driving the conveyor belt 1 to move. When the photoelectric sensor detects the raw material bag 20, the controller makes the rodless cylinder 6 descend. After a proper delay, the rotating drive mechanism 21 automatically stops running, the conveyor belt 1 stops, and the raw material bag 20 just stops in the clamping area of ​​the clamp 4, so that the clamp 4 is closed to clamp the front end of the outer bag. Then the controller makes the rodless cylinder 6 rise and the conveyor belt 1 continues to run. The rodless cylinder 6 drives the lifting plate 3 and the clamp 4 to rise, and the clamp 4 drives the outer bag of the raw material bag 20 to rise. During the rising process of the outer bag, the inner bag will fall out of the outer bag by gravity, and as the conveyor belt 1 continues to move forward, the rodless cylinder 6 drives the lifting plate 3 and the clamp 4 to rise to the initial position and then stops running, so that the clamp 4 opens, and the outer bag can be taken away manually.

[0044] Furthermore, if Figure 1 and Figure 2 As shown, a limit block 7 is also included, which is arranged on the cylinder body of the rodless cylinder 6 and is located above the slider of the rodless cylinder 6.

[0046] On the inner sides of the left and right support members 2, two upper and lower cylinder support seats 8 are simultaneously arranged, and on the left and right rodless cylinders 6, two upper and lower cylinder positioning plates 9 are simultaneously arranged. The spacing between the two upper and lower adjacent positioning bolts 10 on the upper cylinder support seat 8 is equal to the spacing between the two upper and lower adjacent positioning bolts 10 on the lower cylinder support seat 8. By adjusting the installation position of the cylinder positioning plate 9 on the cylinder support seat 8, the upper and lower positions of the rodless cylinder 6 can be adjusted, thereby changing the lifting range of the lifting plate 3 and the clamping claw 4, which can better meet different usage requirements.

[0047] Furthermore, if Figure 2 and Figure 3 As shown, it also includes a positioning seat 11 and a push rod 12. The positioning seat 11 is arranged on the support member 2 and is located below the cylinder support seat 8. The push rod 12 is threadedly connected to the positioning seat 11. The lower end of the push rod 12 is located below the positioning seat 11, and the upper end of the push rod 12 contacts the lower end surface of the cylinder support seat 8. The upper and lower positions of the push rod 12 can be changed by rotating the push rod 12. After the push rod 12 contacts the cylinder support seat 8, the push rod 12 can play a role in supporting the cylinder support seat 8, so that the connection between the cylinder support seat 8 and the support member 2 is more firm and reliable.

[0048] Furthermore, if Figure 1 and Figure 2 As shown, it also includes a mounting plate 13, which is arranged at the lower end of the support member 2, and a positioning hole 14 is opened on the mounting plate 13, and the positioning hole 14 is located at the periphery of the support member 2. The number of the positioning holes 14 is at least three, and all the positioning holes 14 are arranged around the support member 2. Positioning rods are installed at the positioning holes 14, and the mounting plate 13 is fixed on the ground, so that the support member 2 can be fixed on the ground, without drilling holes on the mounting plate 13 on site, and the operation is simpler and more convenient.

[0049] Furthermore, if Figure 1 and Figure 2 As shown, it also includes a reinforcing rib plate 15, which is connected to both the mounting plate 13 and the support member 2.
