DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a soft bag sealing device.

[0034] Reference Figure 1-4 The soft bag sealing device includes a medicine plug 1, a bottom plate 2, a clamping assembly 3 and a pressing assembly 4. The medicine plug 1 is inserted into a conduit 11 of the soft bag, and the bottom plate 2 is fixed on a working surface.

[0035] The clamping assembly 3 includes a fixing frame 31 and a pneumatic clamping jaw 32. The fixing frame 31 is vertically arranged and fixed on the bottom plate 2. The pneumatic clamping jaw 32 is arranged at the top of the fixing frame 31. The pneumatic clamping jaw 32 includes two claw hands 321. The two claw hands 321 move in a direction of approaching or moving away from each other. The two claw hands 321 are fixedly connected to a clamping block 33 on the sides approaching each other. The clamping block 33 is provided with an arc receiving groove 331 on the sides approaching each other. The two arc receiving grooves 331 are assembled into an accommodation groove. The two claw hands 321 move in a direction of approaching each other until the inner wall of the accommodation groove fits the outer wall of the conduit 11. The two claw hands 321 move in a direction of moving away from each other until the clamping block 33 is separated from the conduit 11.

[0036] The catheter 11 includes a first tube body 111 and a second tube body 112 along the axial direction. The second tube body 112 is integrally formed below the first tube body 111 . The diameter of the second tube body 112 is smaller than that of the first tube body 111 .

[0037] The accommodating arc groove 331 includes a first unit segment 3311 and a second unit segment 3312 along the axial direction. The second unit segment 3312 is integrally formed below the first unit segment 3311. The diameter of the second unit segment 3312 is smaller than the diameter of the first unit segment 3311, and the second unit segment 3312 is adapted to the second tube body 112 at the bottom end of the catheter 11. A limiting step 3313 is formed at the connection between the top end of the second unit segment 3312 and the bottom end of the first unit segment 3311. The limiting step 3313 serves as a limiting support for the catheter 11, thereby reducing the possibility of the soft bag falling off when the piston rod of the telescopic cylinder 42 presses down the medicine plug 1.

[0038] The clamping assembly 4 includes a support frame 41 and a telescopic cylinder 42. The support frame 41 is in a "7-shape". The vertical section of the support frame 41 is fixed on the base plate 2, and the cylinder body of the telescopic cylinder 42 is fixed on the horizontal section of the support frame 41. The piston rod of the telescopic cylinder 42 is located directly above the accommodating groove. When the piston rod of the telescopic cylinder 42 descends, it pushes the medicine plug 1 downward.

[0039] An auxiliary block 43 is provided at one end of the piston rod of the telescopic cylinder 42 near the receiving groove. The auxiliary block 43 is cylindrical, and the diameter of the end face of the auxiliary block 43 is larger than the diameter of the medicine plug 1. The piston rod of the telescopic cylinder 42 contacts the medicine plug 1 through the auxiliary block 43, and the top surface of the medicine plug 1 can be in full contact with the bottom surface of the auxiliary block 43, thereby improving the uniformity of the force on the medicine plug 1. In this embodiment, the auxiliary block 43 is made of stainless steel, so that the contact between the auxiliary block 43 and the medicine plug 1 is a hard contact. Compared with the elastic contact, the auxiliary block 43 cannot be deformed, so that the medicine plug 1 can be pushed into place.

[0040] When sealing the soft bag, the staff first inserts the medicine plug 1 into the catheter 11 of the soft bag, and then puts the catheter 11 of the soft bag into the receiving groove of the pneumatic clamp 32. The two claws 321 of the pneumatic clamp 32 move towards each other until the clamping block 33 clamps the catheter 11 of the soft bag. At this time, the top of the medicine plug 1 is located above the pneumatic clamp 32, and then the piston rod of the telescopic cylinder 42 descends and pushes the medicine plug 1 to continue to move downward through the auxiliary block 43, thereby improving the firmness of the connection between the medicine plug 1 and the catheter 11 and improving the sealing effect of the soft bag.

[0041] The bottom end of the piston rod of the telescopic cylinder 42 is coaxially connected with a connecting rod 44, the top end of the connecting rod 44 is fixedly connected with the piston rod of the telescopic cylinder 42, an external thread is provided on the outer peripheral wall of the connecting rod 44, a connecting groove 431 is provided on the top surface of the auxiliary block 43, an internal thread used in conjunction with the external thread is provided on the inner peripheral wall of the connecting groove 431, and the auxiliary block 43 is threadedly connected with the connecting rod 44. Align the connecting rod 44 with the connecting groove 431, rotate the auxiliary block 43 until it is threadedly connected with the connecting rod 44 and tighten it to fix the auxiliary block 43.

[0042] A friction strip 5 is provided on the inner wall of the first unit section 3311 of the receiving arc groove 331. A plurality of friction strips 5 are provided equidistantly along the circumference of the receiving arc groove 331. The inner wall of the friction strip 5 is interference-fitted with the outer wall of the catheter 11. The provision of the friction strip 5 increases the friction between the clamping block 33 and the soft bag catheter 11, improves the firmness of the pneumatic clamping jaws 32 clamping the soft bag, and further reduces the possibility of the soft bag falling when the piston rod of the telescopic cylinder 42 presses down the medicine plug 1. The friction strip 5 is made of silicone, which not only has a high friction force but also protects the catheter 11 of the soft bag.

[0043] The friction strip 5 is detachably connected to the clamping block 33. A mounting groove 332 is provided on the top surface of the clamping block 33. The mounting groove 332 is connected to the accommodating arc groove 331. The end surface of the mounting groove 332 is dovetail-shaped. The friction strip 5 includes a mounting portion 51 and a tightening portion 52. The mounting portion 51 is also dovetail-shaped and inserted into the mounting groove 332. The tightening portion 52 is symmetrically arranged with the mounting portion 51. The tightening portion 52 is located outside the mounting groove 332. The length of the friction strip 5 is less than the depth of the mounting groove 332.

[0044] A cover plate 6 is provided on the top surface of the friction strip 5, and the cover plate 6 covers all the friction strips 5 on each receiving arc groove 331. An embedding groove 61 for embedding the cover plate 6 is provided on the top surface of the clamping block 33, and the embedding groove 61 is communicated with the mounting groove 332. The top surface of the cover plate 6 is flush with the top surface of the clamping block 33, and the inner wall of the cover plate 6 is flush with the inner wall of the first unit section 3311 of the receiving arc groove 331. Countersunk screws 7 are provided at both ends of the cover plate 6, and the countersunk screws 7 are threadedly connected with the inner wall of the embedding groove 61 after passing through the cover plate 6. After long-term use, if the friction force of the friction strip 5 decreases, the friction strip 5 is replaced to ensure the firmness of the pneumatic clamp 32 to clamp the soft bag. After the friction strip 5 is inserted into the mounting groove 332 from top to bottom, the cover plate 6 is covered above the friction strip 5, and then the cover plate 6 is fixed by the countersunk screw 7 to fix the friction strip 5.

[0045] The implementation principle of a soft bag sealing device in the embodiment of the present application is:

[0046] When sealing the soft bag, the staff first inserts the medicine plug 1 into the catheter 11 of the soft bag, and then puts the catheter 11 of the soft bag into the receiving groove of the pneumatic clamp 32. The two claws 321 of the pneumatic clamp 32 move towards each other until the clamping block 33 clamps the catheter 11 of the soft bag. At this time, the top of the medicine plug 1 is located above the pneumatic clamp 32, and then the piston rod of the telescopic cylinder 42 descends and pushes the medicine plug 1 to continue to move downward, pressing the medicine plug 1. The operation is convenient and the firmness of the connection between the medicine plug 1 and the catheter 11 is improved. Finally, the staff holds the soft bag and waits for the claws 321 of the pneumatic clamp 32 to release until the clamping block 33 is separated from the soft bag.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
