Specific process is, first fold the film, then carry out insert M edge operation on its both sides. However, for the liquid bag needing to install valve mouth to realize liquid filling function, the traditional liquid bag production process has obvious defects.
[0003] In the traditional film bag production process, since it is unnecessary to install valve mouth, its used conveying roller is all ordinary cylindrical structure. When being applied to the production of liquid bag with valve mouth, this cylindrical conveying roller cannot provide through space for valve mouth, will cause valve mouth to be hindered even damaged in the conveying process, makes liquid bag with valve mouth unable to smoothly pass through conveying roller to complete subsequent processing process. Meanwhile, the traditional film folding triangular frame also does not consider the existence of valve mouth in the structural design, makes valve mouth difficult to smoothly pass through in the film folding process, seriously affects the production efficiency and quality of liquid bag with valve mouth, causes the existing process to be unable to satisfy the production demand of liquid bag with valve mouth, and a novel device is urgently needed to solve the above problems.

[0017] The embodiments and drawings of the utility model are described below Figs. 1-3 The technical scheme of the utility model is further described.
[0018] Embodiment 1
[0019] A liquid bag with valve port inserts M edge device, including: rack 1, feed guide roller group 2, triangular roller group 3, discharge guide roller group 4, support plate 5 and insert edge assembly 6, the feed guide roller group 2 includes several groups of side roller 21, inclined roller 22 and horizontal roller 23, the side roller 21 is rotatably arranged on the right side of the rack 1, the side roller 21 on the right side of the liquid bag film is provided with liquid valve through slot 7, the inclined roller 22 is rotatably arranged on the top of the rack 1, the horizontal roller 23 is rotatably arranged on the top rear side of the rack 1 and is provided with liquid valve through slot 7, the triangular roller group 3 includes two groups of round rollers 31, the upper ends of the two groups of round rollers 31 are fixed on the rack 1, the lower ends of the two groups of round rollers 31 gradually approach and are fixedly connected at the bottom, the liquid bag film is folded in half through the triangular roller group 3, the discharge guide roller group 4 is rotatably arranged on the rack 1 and is located below the connecting part of the round roller 31, the discharge guide roller group 4 includes left guide roller 41 and right guide roller 42, the left guide roller 41 is provided with liquid valve through slot 7, the support plate 5 is located on the left side of the discharge guide roller group 4, and the inside of the folded liquid bag film is pried open, the insert edge assembly 6 is arranged on the left side of the support plate 5, and the liquid bag film on both sides after being pried open is inserted M edge through the insert edge assembly 6.
[0020] As Figs. 1-3 As shown in the embodiment 1, when the liquid bag with valve port inserts M edge device works, the liquid bag film first passes through the feed guide roller group 2. The side roller 21, the inclined roller 22 and the horizontal roller 23 in the feed guide roller group 2 cooperate to preliminarily guide and convey the liquid bag film, wherein the side roller 21 located on the right side of the liquid bag film and provided with liquid valve through slot 7, and the horizontal roller 23 provided with liquid valve through slot 7, provide a passing space for the valve port on the liquid bag film, so that the valve port can smoothly pass through this stage.
[0021] Then, the liquid bag film reaches the triangular roller group 3. In the conventional process, folding the triangular frame with a rectangular cross-section can cause the valve port to be stuck due to the lack of fitting space when moving; while the triangular roller group 3 of the device is composed of two groups of round rollers 31, the structural characteristics of the circular cross-section can effectively reduce the contact friction and obstruction between the valve port. When the liquid bag film moves along the two groups of round rollers 31 from the upper end to the bottom end, the curved surface of the round roller 31 can provide an arc-shaped transition channel for the valve port, so that the valve port can smoothly pass along the curved surface, and at the same time, the two groups of round rollers 31 are gradually close and fixedly connected at the lower end, completing the folding operation of the liquid bag film.
[0022] The folded liquid bag film continues to be transported by the discharge guide roller group 4, which includes a left guide roller 41 and a right guide roller 42, wherein the left guide roller 41 is provided with a liquid valve through slot 7 to ensure that the valve port can continue to pass smoothly. Subsequently, the support plate 5 opens the inside of the folded liquid bag film, and finally the inserted edge assembly 6 inserts the M edge on both sides of the opened liquid bag film to complete the entire liquid bag M edge insertion process.
[0023] The conventional liquid bag production adopts a two-layer film composite method, and multiple edge sealing operations are required between the two layers of film to ensure the sealing of the liquid bag. Since the edge sealing is connected together by heat sealing or other methods, there are many seams. After the liquid bag is filled with liquid, the internal pressure increases, and these seams become potential risk points for liquid leakage. Once the process precision of the edge sealing is insufficient or the heat sealing strength is not enough, the liquid is likely to seep out from the seams.
[0024] And the liquid bag produced by the device is folded by the triangular roller group 3 after the single-layer film is folded, and then the M edge is inserted on both sides of the opened liquid bag film by the inserted edge assembly 6, and only a small amount of necessary edge sealing is required subsequently. Compared with the two-layer film composite method, a large number of edge sealing seams are reduced. Because the edge sealing seams are reduced, it means that the liquid leakage channels are reduced. Under the action of the internal pressure of the liquid in the liquid bag, there are fewer seams for the liquid to penetrate, thereby greatly reducing the possibility of leakage.
[0025] As a further preferred embodiment, the left guide roller 41 is provided below the conveying guide roller 43, and the conveying guide roller 43 is provided with a liquid valve through slot 7. The addition of the conveying guide roller 43 below the left guide roller 41 further enhances the conveying capacity of the liquid bag film, ensuring that the liquid bag film can be transported more smoothly and smoothly during the discharge guide roller group 4 stage. At the same time, the liquid valve through slot 7 provided on the conveying guide roller 43 cooperates with the liquid valve through slot 7 on the left guide roller 41 to continuously provide a passing space for the valve port, ensuring that the valve port is not obstructed during the conveying process, so that the liquid bag film can be smoothly conveyed to the next process.
[0026] As a further preferred embodiment, the left side of the conveying guide roller 43 is provided with a conveying guide roller group 44, the conveying guide roller group 44 is located at the right side of the support plate 5, and the upper conveying guide roller one 45 in the conveying guide roller group 44 is provided with the liquid valve through slot 7. The conveying guide roller group 44 is arranged at the left side of the conveying guide roller 43, which further optimizes the conveying path of the liquid bag film between the discharging guide roller group 4 and the support plate 5, so that the liquid bag film can be conveyed to the support plate 5 more accurately and stably. The upper conveying guide roller one 45 in the conveying guide roller group 44 is provided with the liquid valve through slot 7, which continuously provides a passing space for the valve port during the conveying of the liquid bag film, ensures the smooth passing of the valve port through this stage, avoids the interference between the valve port and the conveying guide roller group 44, and ensures that the liquid bag film can smoothly enter the support plate 5 for the opening operation.
[0027] As a further preferred embodiment, the side roller 21 is provided in four groups, and the lower two groups of the side roller 21 are provided with the liquid valve through slot 7, and the upper two groups of the side roller 21 are not provided with the liquid valve through slot 7. The side roller 21 is arranged in four groups, and the lower two groups and the upper two groups of the side roller 21 are designed differently. The lower two groups of the side roller 21 are provided with the liquid valve through slot 7, which can provide a passing space for the valve port located below the liquid bag film at the initial stage of the liquid bag film feeding, so that the valve port can smoothly pass through the initial stage of the feeding guide roller group 2; the upper two groups of the side roller 21 are not provided with the liquid valve through slot 7, which reduces the manufacturing cost and complexity of the device while ensuring the effective guiding and conveying of the liquid bag film, and does not affect the overall conveying of the liquid bag film and the passing of the valve port.
[0028] The above describes the preferred embodiments of the present application in detail. It should be understood that those skilled in the art can make many modifications and changes without creative labor according to the concept of the present application. Therefore, any technical solution obtained by logical analysis, reasoning or limited experiment on the basis of the prior art according to the concept of the present application shall be within the protection scope defined by the claims.
