[0029] The following is combined with Figure 1-8 This application is described in further detail.

[0030] The embodiment of the present application discloses a co-extruded film bag booster.

[0031] Embodiment 1

[0032] Reference Figure 1-3The co-extruded film bag booster includes a booster body. The booster body 1 is in the shape of a waist plate. A booster groove 2 is provided in the middle of the booster body 1 in the width direction. The booster groove 2 runs through both sides of the booster in the thickness direction. The co-extruded film bag passes through the booster groove 2. The inner walls of the booster groove 2 on both sides in the width direction abut against the outer walls of the bag body on both sides in the thickness direction of the co-extruded film bag. The two ends of the booster groove 2 in the length direction extend to the two ends close to the length direction of the booster body 1. The length of the booster groove 2 is greater than the width of the co-extruded film bag.

[0033] The two sides of the booster body 1 in the thickness direction are respectively an arc surface 11 and a flat surface 12. In this embodiment, the arc surface 11 of the booster body 1 is located above the flat surface 12. The booster groove 2 is gradually expanded from the arc surface 11 to the flat surface 12. During operation, the co-extruded film bag passes through the booster groove 2 from the side with a wider opening of the booster groove 2, which improves the smoothness of the co-extruded film bag passing through the booster groove 2.

[0034] The inner wall sides at both ends of the boosting groove 2 in the depth direction are both rounded, which reduces the possibility of scratching the co-extruded film bag caused by the inner wall of the boosting groove 2, thereby protecting the co-extruded film bag.

[0035] The flat surface 12 of the booster body 1 is provided with a weight-reducing groove 3, which is arranged around the outer circumference of the booster groove 2, thereby reducing the weight of the entire booster.

[0036] The implementation principle of a co-extruded film bag booster in the first embodiment of the present application is:

[0037] The co-extruded film bag is passed through the booster groove 2 from the side with the wider opening of the booster groove 2, and the inner walls on both sides of the width direction of the booster groove 2 are abutted against the outer walls of the bag on both sides of the thickness direction of the co-extruded film bag, so that the bag body on both sides of the thickness direction of the co-extruded film bag fits tightly. The staff holds the two side walls of the booster body 1 in the width direction, slides the booster body 1 along the bottom of the co-extruded film bag to the outlet, and the viscous liquid medicine in the co-extruded film bag is evenly pushed out of the co-extruded film bag.

[0038] Embodiment 2

[0039] Reference Figure 4-8 The difference between the second embodiment of the present application and the first embodiment is that an adjustment groove 4 is opened in the middle of the width direction of the booster body 1, and the width of the adjustment groove 4 is greater than the width of the booster groove 2. Two adjustment plates 5 are slidably arranged in the adjustment groove 4, and the two adjustment plates 5 slide in the direction of approaching or moving away from each other, and a booster groove 2 is formed between the two adjustment plates 5. The booster groove 2 is still gradually expanded in the direction from the arc surface 11 to the straight surface 12.

[0040] The two ends of the adjusting plate 5 in the length direction are connected with the limiting blocks 51 , and the inner walls of the two ends of the adjusting groove 4 in the length direction are provided with limiting grooves 41 for the limiting blocks 51 to slide, thereby improving the sliding stability of the adjusting plate 5 .

[0041] A control assembly 6 for controlling the sliding of the adjustment plate 5 is arranged in the weight reduction groove 3. One adjustment plate 5 corresponds to multiple groups of control assemblies 6. In this embodiment, one adjustment plate 5 corresponds to three groups of control assemblies 6. The movable groove 31 at one adjustment plate 5 can accommodate multiple groups of control assemblies 6 at the same time. The multiple groups of control assemblies 6 at one adjustment plate 5 are arranged equidistantly along the length direction of the movable groove 31 to improve the uniformity of the force on the adjustment plate 5.

[0042] Each control assembly 6 includes a control rod 61, which is rotatably connected to the adjustment plate 5. A receiving circular groove 52 for the control rod 61 to penetrate is provided on the side of the adjustment plate 5 that is away from each other. The end of the control rod 61 that penetrates the adjustment plate 5 is coaxially connected to the limiting circular plate 62. A limiting circular groove 53 for the limiting circular plate 62 to rotate is provided on the inner wall of the accommodating circular groove 52. The limiting circular plate 62 rotates in the limiting circular groove 53 and drives the adjustment plate 5 to slide.

[0043] The inner wall of the weight-reducing groove 3 is provided with a movable groove 31 for the control rod 61 to move, and the movable groove 31 is located on both sides of the width direction of the boosting groove 2. The wall between the movable groove 31 and the adjustment groove 4 is a support wall 7. The control rod 61 passes through the support wall 7 and is threadedly connected with the corresponding support wall 7. The control rod 61 is provided with an external thread 611 at the position of the support wall 7. The support wall 7 is provided with a threaded hole 71 that matches the external thread 611 of the control rod 61. Since the control rod 61 is threadedly connected with the support wall 7, when the control rod 61 is rotated, the control rod 61 can drive the adjustment plate 5 to slide through the limiting circular plate 62.

[0044] The control rod 61 is rotated to adjust the distance between the two adjustment plates 5, thereby adjusting the width of the boosting groove 2, so as to adapt to the co-extruded film bags with different bag thicknesses, thereby improving the adaptability of the booster.

[0045] The control rods 61 of the multiple control assemblies 6 on one adjusting plate 5 are synchronously rotated through the synchronous toothed belt 8. A plurality of auxiliary teeth 612 are equidistantly arranged on the outer peripheral wall of each control rod 61 away from the end of the adjusting plate 5, so that the control rod 61 is meshed with the synchronous toothed belt 8 for transmission. The auxiliary teeth 612 also facilitate the staff to rotate the control rod 61. Rotating one control rod 61 on the same side of the adjusting plate 5 can synchronously rotate multiple control rods 61 on this side of the adjusting plate 5, which is convenient to operate and has high synchronization of movement of various places in the length direction of the adjusting plate 5.

[0046] Friction strips 9 are arranged on the outer walls on both sides of the booster body 1 in the width direction. Multiple friction strips 9 are arranged equidistantly along the thickness direction of the booster body 1 on each side in the width direction of the booster body 1 to reduce the possibility of slipping when the staff slides the booster body 1.

[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.
