TECHNICAL FIELD
[0001] The utility model belongs to the medical liquid bag production technical field, specifically, relate to a medical liquid bag belt conveyor. BACKGROUND
[0002] In the field of medical devices, medical liquid bags for holding various liquids have very wide applications, including but not limited to various models of drainage bags, feeding bags, infusion bags, and nutrient storage bags, etc. The manufacturing process generally adopts hot press forming, that is, through the compression of the upper and lower molds of the forming machine, the two pieces of strip-shaped material are fused at the contact point with the mold to form a bag body.
[0003] During this process, the welded bag body as a whole can still be considered as a long roll in sheet form, which needs to be transported by the conveying device from the welding device to the next station for production.
[0004] For example, the utility model patent "A conveying mechanism suitable for drainage bags" with publication number CN220998587U discloses a conveying device suitable for drainage bags, which can convey the welded drainage bags to the next station. In this device, a "pressing plate" is arranged above the "conveying belt" to press and hold the sheet-shaped bag body for conveying and transferring, ensuring the flatness of the bag body.
[0005] However, in actual use, it is found that the work of this device is intermittent, as stated in the specification: "such a cycle is repeated to realize the intermittent movement of the conveying belt", that is, when working, the pressing plate needs to be lifted first, moved from the rear end to the front end, then lowered to press the drainage bag, then moved from front to back, after conveying this batch of drainage bags, the conveying belt stops working, and the pressing plate is lifted again to return to the front end to start the next batch of conveying.
[0006] Obviously, the problem of this process is that during the process of the pressing plate completing one conveying from back to front, other devices on both sides are simultaneously pulling the welded liquid bag, so during this period, since the pressing plate is not pressing the liquid bag in the air, the liquid bag on the conveying belt may be deflected or stacked due to the pulling action of both sides, thereby affecting the normal operation of the normal production line, resulting in reduced production efficiency. UTILITY MODEL CONTENTS

[0010] The second pressing mechanism is arranged behind the first pressing mechanism, the first pressing mechanism synchronously moves with the conveying mechanism to press the medical liquid bag, and the second pressing mechanism presses the medical liquid bag which stops moving after the first pressing mechanism completes a pressing operation.
[0011] Further, the first pressing mechanism comprises a first press plate which can be lifted, the second pressing mechanism comprises a second press plate which can be lifted, and the initial position and the end position of the first press plate for pressing the medical liquid bag are the same point and close to the second press plate.
[0012] Further, the first press plate presses the medical liquid bag at the feeding end of the conveying mechanism.
[0013] Further, the second press plate presses the medical liquid bag at the discharging end of the conveying mechanism.
[0014] Further, the device comprises a workbench, and the conveying mechanism, the first pressing mechanism and the second pressing mechanism are all arranged on the workbench.

[0024] The present invention will be further described below with reference to specific embodiments.
[0025] like Figure 1 As shown, the medical liquid bag belt conveyor of this utility model includes a horizontal workbench 1, on which a first pressing mechanism 2, a second pressing mechanism 3 and a conveying mechanism 4 are provided. The conveying mechanism 4 is used to convey the welded medical liquid bags.
[0026] Specifically, the second pressing mechanism 3 is located behind the first pressing mechanism 2. In this embodiment, the conveying mechanism 4 includes a conveyor belt 41, and the second pressing mechanism 3 is located near the unloading end of the conveyor belt 41. As can also be seen from the figure, when not in operation, the first pressing mechanism 2 is also relatively close to the second pressing mechanism 3.
[0027] In structure, the first pressing mechanism 2 comprises a first pressing plate 21, and the second pressing mechanism 3 comprises a second pressing plate 31. Both of the pressing plates can be lifted and lowered in the vertical direction under the action of the motor, and the positions of both of the pressing plates are located directly above the conveying belt 41, so that the medical liquid bags on the conveying belt 41 can be pressed. In addition, in other embodiments, the lengths of the first pressing plate 21 and the second pressing plate 31 can be close to the width of the conveying belt 41, so that the pressing effect on the medical liquid bags can be maximized without affecting the normal operation of the conveying belt 41, and the medical liquid bags on the left and right sides of the conveying belt 41 can be prevented from being affected in quality due to improper pressing.
[0028] In addition, the workbench 1 is internally provided with a guide rail 5, and the first pressing mechanism 2 further comprises a sliding member 6 which can slide on the guide rail 5. The sliding member 6 is driven to move by an electric cylinder, and the sliding member 6 is fixedly connected to the first pressing plate 21 through a connecting plate 7 from the side of the conveying belt 41 and the guide rail 5. Therefore, the forward and backward movement of the first pressing mechanism 2 relative to the conveying belt 41 can be realized.
[0029] In this embodiment, the initial position and the end position of the first pressing plate 21 for pressing the medical liquid bags are the same point and close to the second pressing plate 31, and the second pressing plate 31 only presses the medical liquid bags at the discharge end of the conveying belt 41. Therefore, the working principle of the device can be obtained.
[0030] As shown in FIG. 1, Figures 3 to 6 in the initial state, the second pressing plate 31 is close to the discharge end of the conveying belt 41, the first pressing plate 21 is in front of and close to the second pressing plate 31, the second pressing plate 31 is lowered and pressed on the conveying belt 41, and the first pressing plate 21 remains empty. When the last device in the production line helps to convey the welded medical liquid bag conveying belt 41, the second pressing plate 31 is first lifted to release the pressing on the conveying belt 41, and then the first pressing plate 21 moves to the feeding end of the conveying belt 41 under the action of the sliding member 6, and after reaching the position, it is lowered to press the medical liquid bags just entering the conveying belt 41, and moves backward with the conveying belt 41. In this process, the second pressing plate 31 always remains empty.
[0031] When the position of the first pressing plate 21 moves to the position close to the second pressing plate 31, the conveying belt 41 stops moving, the second pressing plate 31 is lowered to press the medical liquid bags, and at the same time, the first pressing plate 21 is lifted. At this time, the devices before and after the device in the production line are waiting for the completion of the work to avoid affecting the medical liquid bags due to the pulling of both sides. After the work is completed, the second pressing plate 31 is lifted, and the next batch of medical liquid bags has been conveyed from the last station. At this time, the first pressing plate 21 continues to move to the feeding end of the conveying belt 41 to press and convey the next batch of medical liquid bags, and the process is repeated.
[0032] In addition, in other embodiments, the second pressing mechanism 3 can also be designed to be movable, which can also move horizontally on the conveying belt 41 through the action of the connecting plate and the sliding piece, so as to meet the pressing requirements of the medical liquid bag at different times and in different states.
