[0036] Reference will be made in detail to various embodiments of the present invention, examples of which are presented in the accompanying drawings and described below. Although the present invention will be described in conjunction with exemplary embodiments, it should be understood that this specification is not intended to limit the present invention to these exemplary embodiments. On the contrary, the present invention is intended to cover not only these exemplary embodiments, but also various alternative forms, modified forms, equivalent forms and other embodiments that may be included in the spirit of the present invention and within the scope defined by the appended claims.

[0037] Combine the following Figures 1 to 4 The filling bag-dropping prevention device of the utility model is described.

[0038] Figure 1 This is a schematic diagram of the overall structure of the filling bag drop prevention device of the utility model embodiment arranged on the frame of the filling equipment. Specifically, Figure 1 It is observed from above the frame of the filling equipment.

[0039] First of all, it should be explained that the filling bag-dropping prevention device of the utility model is used for a filling device of an infusion bag. The interface of the infusion bag is set as a hose 100. The filling device has a frame 200.

[0040] like Figure 1 As shown, the filling bag-drop prevention device of the present invention comprises: a guide rail 300 , an action assembly 400 , a clamping assembly 500 , a filling assembly 600 and a pressing plate 700 .

[0041] The guide rail 300 is mounted on the frame 200 of the filling device. The action component 400 is connected to the guide rail 300 and can move in a predetermined direction. The clamping component 500 is mounted on the frame 200 of the filling device and is used to clamp the hose 100 of the infusion bag. The filling component 600 is connected to the action component 400 and is provided with a filling nozzle 610 corresponding to the hose 100. The squeezing plate 700 is mounted on the frame 200 of the filling device. Among them, the action of the action component 400 can drive the filling component 600 to move so that the filling nozzle 610 is inserted into the hose 100, and can drive the infusion bag to move to a predetermined position so that the squeezing plate 700 squeezes the hose 100.

[0042] Specifically, in an exemplary embodiment of the utility model, the guide rail 300 is a linear guide rail. The action assembly 400 includes a telescopic cylinder 410 and a lifting cylinder 420. The telescopic cylinder 410 can be mounted on the frame 200 of the filling device. The telescopic cylinder 410 is provided with a telescopic shaft 411, and the telescopic shaft 411 can move in the direction of the guide rail 300. One end of the lifting cylinder 420 along the length direction is connected to the guide rail 300. The other end of the lifting cylinder 420 along the length direction is provided with a lifting shaft 421, and the lifting shaft 421 can move in a direction perpendicular to the guide rail 300. The filling assembly 600 is connected to the lifting shaft 421, so that the filling assembly 600 can move in a direction perpendicular to the guide rail 300 driven by the lifting shaft 421. The middle part of the lifting cylinder 420 along the length direction is connected to the telescopic shaft 411. The movement of the telescopic shaft 411 can drive the lifting cylinder 420 to move a first predetermined distance along the guide rail 300 in the first direction, and the lifting shaft 421 drives the filling assembly 600 to move a second predetermined distance in the second direction, so that the filling nozzle 610 is inserted into the hose 100. The movement of the telescopic shaft 411 can drive the lifting cylinder 420 to move a third predetermined distance along the guide rail 300 in the third direction, so that the infusion bag moves to a predetermined position, so that the squeezing plate 700 squeezes the hose 100. Here, the first direction refers to Figure 1 The second direction refers to the direction of D1 shown in FIG. Figure 1 The third direction refers to the direction of D2 shown in Figure 1 The direction of D3 shown in . The first direction and the third direction are opposite directions. Preferably, the first predetermined distance and the third predetermined distance are the same in size.

[0043] In addition, by measuring the first predetermined distance moved in the first direction and the third predetermined distance moved in the third direction by the guide rail 300, the accuracy of the movement can be ensured, so that the filling nozzle 610 can be inserted into the hose 100 more accurately, and the squeezing plate 700 can squeeze the hose 100 with an appropriate force, which is more conducive to the smooth filling of the filling liquid into the infusion bag.

[0044] The filling bag-drop prevention device of the utility model drives the filling assembly 600 to move through the action of the action assembly 400, so that the filling nozzle 610 is inserted into the hose 100 of the infusion bag and moves to a predetermined position, so that the squeezing plate 700 squeezes the hose 100. The squeezing force of the squeezing plate 700 can prevent the hose 100 from being separated from the filling nozzle 610, so that the filling liquid can be smoothly filled into the infusion bag, avoiding the waste of the filling liquid and ensuring the production efficiency.

[0045] According to an exemplary embodiment of the present utility model, Figure 2 and Figure 3 As shown, the extrusion plate 700 includes a plate body 710 and an extrusion portion 720. Specifically, the plate body 710 is mounted on the frame 200 of the filling device and has a bent end 711 bent upward. The extrusion portion 720 is connected to the bent end 711 of the plate body 710 and is arranged to correspond to the upper part of the side wall of the hose 100, so that the extrusion portion 720 can be extruded to the upper part of the side wall of the hose 100. By adjusting the bending height of the bent end 711, the position of the extrusion portion 720 extruding to the side wall of the hose 100 can be adjusted. In addition, the squeezing force applied by the squeezing portion 720 to the side wall of the hose 100 is not less than 10N, so that although the filling bag-dropping prevention device of the present invention only squeezes one side of the hose 100 through the squeezing portion 720, the side wall of one side of the hose 100 can be firmly located between the filling nozzle 610 and the squeezing portion 720, to ensure that during the filling process, the hose 100 is difficult to detach from the filling nozzle 610, thereby achieving the purpose of preventing the infusion bag from falling.

[0046] Furthermore, the plate body 710 is provided with two strip holes 730, which are respectively provided at both ends of the plate body 710 and extend along the width direction of the plate body 710. By inserting fasteners such as bolts into the two strip holes 730, the plate body 710 can be fixed to the frame 200 of the filling device, and by adjusting the position where the fasteners are inserted into the strip holes 730, the position where the plate body 710 is fixed to the frame 200 of the filling device can be adjusted, thereby adjusting the magnitude of the squeezing force of the squeezing part 720 squeezing the side wall of the hose 100, thereby further ensuring that the hose 100 will not be separated from the filling nozzle 610 during the filling process, thereby achieving the purpose of preventing the infusion bag from falling.

[0047] According to an exemplary embodiment of the present utility model, Figure 4As shown, the clamping assembly 500 includes a clamping hand 510 and an opening clamping cylinder 520. Specifically, one end of the clamping hand 510 is provided with a clamping opening 511. The clamping opening 511 is used to clamp the hose 100. The opening clamping cylinder 520 is mounted on the frame 200 of the filling device and connected to the other end of the clamping hand 510. The opening clamping cylinder 520 can control the clamping force of the clamping opening 511 so that the clamping opening 511 can open or clamp the hose 100. Among them, before the liquid is filled into the infusion bag, the opening clamping cylinder 520 controls the clamping opening 511 to clamp the hose 100 of the infusion bag so that the filling nozzle 610 can be smoothly inserted into the hose 100. After the filling nozzle 610 is inserted into the hose 100, the opening clamping cylinder 520 controls the clamping opening 511 to open so that the hose 100 can be separated from the clamping opening 511, so that the infusion bag can be driven by the filling nozzle 610 to move to a predetermined position.

[0048] According to an exemplary embodiment of the present utility model, Figure 1 As shown, the filling assembly 600 further includes a liquid pipeline 620 and a filling pneumatic valve 630. Specifically, the liquid pipeline 620 is connected to the lifting shaft 421, and a filling nozzle 610 is provided at one end of the liquid pipeline 620. When the lifting shaft 421 moves, the lifting shaft 421 can drive the liquid pipeline 620 to move, and drive the filling nozzle 610 to move, so that the filling nozzle 610 can be inserted into the hose 100. Among them, the other end of the liquid pipeline 620 can be connected to a storage device for filling liquid. The filling liquid can flow in the liquid pipeline 620 to the filling nozzle 610, and be filled into the infusion bag through the hose 100.

[0049] The filling pneumatic valve 630 is provided on the liquid pipeline 620 and can control the connection and disconnection of the liquid pipeline 620, thereby controlling the filling amount. Specifically, when the filling nozzle 610 is inserted into the hose 100 and the squeezing plate 700 squeezes the hose 100 to be filled, the filling pneumatic valve 630 controls the liquid pipeline 620 to be connected, so that the filling liquid flows in the liquid pipeline 620 to the filling nozzle 610, and is filled into the infusion bag through the hose 100. When the filling amount reaches a predetermined value, the filling pneumatic valve 630 promptly controls the liquid pipeline 620 to be disconnected to avoid waste of the filling liquid.

[0050] According to an exemplary embodiment of the present utility model, Figure 1 As shown, the filling bag-drop prevention device of the present invention further comprises a conveyor belt 800. The conveyor belt 800 is arranged on the frame 200 of the filling device, and when the infusion bag moves to a predetermined position and is filled, the infusion bag can lean against the conveyor belt 800, thereby preventing the hose 100 from being separated from the filling nozzle 610 due to the gravity of the infusion bag itself after large-capacity filling.

[0051] The operation of the filling bag-dropping prevention device of the present invention will be described below in conjunction with the accompanying drawings.

[0052] When liquid needs to be filled into the infusion bag, first, the telescopic cylinder 410 controls the telescopic shaft 411 to drive the lifting cylinder 420 to move a first predetermined distance in the first direction along the guide rail 300, and the lifting cylinder 420 controls the lifting shaft 421 to drive the filling assembly 600 to move a second predetermined distance in the second direction, so that the filling nozzle 610 is inserted into the hose 100. In this process, the clamping cylinder 520 controls the clamping mouth 511 to clamp the hose 100 to ensure that the filling nozzle 610 can be smoothly inserted into the hose 100.

[0053] Then, the clamp opening cylinder 520 controls the clamping opening 511 to open, so that the hose 100 can be separated from the clamping opening 511. The telescopic cylinder 410 controls the telescopic shaft 411 to drive the lifting cylinder 420 to move a third predetermined distance in the third direction along the guide rail 300, and at the same time drives the filling assembly 600 connected to the lifting shaft 421 to move a third predetermined distance in the third direction, so that the infusion bag moves to a predetermined position, so that the squeezing part 720 of the squeezing plate 700 squeezes the hose 100.

[0054] Finally, the filling pneumatic valve 630 controls the liquid pipeline 620 to be connected, so that the filling liquid flows in the liquid pipeline 620 to the filling nozzle 610, and is filled into the infusion bag through the hose 100. When the filling amount reaches a predetermined value, the filling pneumatic valve 630 promptly controls the liquid pipeline 620 to be disconnected to avoid the waste of the filling liquid. At this point, the filling of the infusion bag is completed.
