[0016] The present invention will be described more fully below with reference to embodiments. The present invention may be embodied in many different forms and should not be construed as being limited to the exemplary embodiments described herein.

[0017] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” may be used herein to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, an element described as being “down” of another element or feature would be positioned “up” of that other element or feature. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0018] like Figure 2 , Figure 3 As shown, the double-chamber bag clamp in this embodiment includes a support frame 1, a positioning post 3, and a nozzle fixing plate 6; the positioning post 3 corresponds to the positioning hole 10 on the double-chamber bag body and is used to fix the bottom of the bag body; a nozzle groove is provided on one side of the nozzle fixing plate 6; fixing the nozzle 11 in the nozzle groove can make the bag body flatter when the clamp fixes the bag body; and reduce the condensate water adhering to the bag body during the sterilization process.

[0019] Both ends of the mouth tube fixing plate 6 can be directly connected to the frame; auxiliary traction arms aligned with the length of the bag can be set at both ends of the mouth tube groove; the strength requirements of the mouth tube fixing plate 6 are reduced; so that the thickness of the mouth tube fixing plate 6 can be thinner.

[0020] The support frame 1 can adopt a rectangular frame; the space occupied is smaller when stacked.

[0021] The length direction of the rectangle is the top end and the bottom end; the positioning column is fixedly arranged at the top end side of the support frame; and the mouth tube fixing plate is fixedly arranged at the bottom end side of the support frame. The top end and the bottom end of the support frame are both provided with ventilation holes. By opening the ventilation holes, the ventilation conditions of the two ends of the bag body at the bottom and the top can be improved.

[0022] The first ventilation hole 5 arranged at the top end of the support frame is located in the middle part, and the length should be greater than one third of the width of the double-chamber bag body.

[0023] The second ventilation hole 8 arranged at the bottom side of the support frame is located in the middle part, and the length should be greater than one fourth of the width of the double-chamber bag body.

[0024] In order to improve the ventilation condition of the shoulder part of the bag body, the two ends of the length direction of the ventilation hole arranged at the bottom side of the support frame are further provided with a third ventilation hole 2 as an auxiliary ventilation hole.

[0025] The four edge frames of the support frame 1 are all provided with ventilation grooves; the first ventilation groove 4 is located at the front and back sides of the top edge frame and the bottom edge frame; and the second ventilation groove 7 is located at the left and right edge frames; which is beneficial to improve the ventilation condition between the clamps and the clamps; and between the clamps and the bag body.

[0026] The inner cavity width of the support frame 1 can be set to be greater than the width of the bag body, so that the space between the width direction of the bag body and the inner wall of the support frame is larger; the steam is prevented from being blocked in the space during sterilization; and the chance of the bag body being attached is reduced.

[0027] The inner wall is provided with a support arm extending inward; the positioning column 3 is arranged at the end of the support arm; so that an air duct is formed between the outer edge of the bag body and the support frame. The support arm can extend inward from the inner wall of the left and right ends; or extend downward from the top wall.

[0028] A central support arm is arranged at the position corresponding to the weak welding strip between the powder cavity and the liquid cavity; the central support arm is integrally arranged with the edge frame at both ends; the middle part of the bag body is supported, the pressure of the bag body on the positioning column and the mouth tube fixing plate is reduced, and the bag body is more flat.

[0029] A plurality of support protrusions 9 can be arranged at the position where the central support arm contacts the bag body; the contact area between the two is reduced, and the ventilation condition of the contact area is improved.

[0030] During the sterilization operation, the double-chamber bag clamp in the embodiment is used to fix the double-chamber bag; the double-chamber bag clamps are stacked together; the steam flows in the gap between the double-chamber bag clamps and the bag body; the resistance is smaller than that of the original clamp; after the sterilization operation, the condensate water attached to the bag body is also less, which is convenient for drying treatment.

[0031] Similarly, during the drying operation, the hot air for drying flows in the gap between the double-chamber bag clamp and the bag body; the resistance is smaller than that of the original clamp; the flow rate is faster, and the drying efficiency is high. The ventilation conditions of the bag body shoulder on both sides of the mouth tube, both sides of the bag body, and the bottom of the bag body are improved, and no residual water is left after the drying treatment.

[0032] The above examples are only used to illustrate the present application, and in addition thereto, there are a variety of different embodiments, and these embodiments are all conceivable by those skilled in the art after understanding the idea of the present application, therefore, they are not listed one by one here.
