Description

Technical Field

[0001] This utility model belongs to the technical field of sealing and packaging devices, and particularly relates to an RO membrane sealing and packaging device. Background Technology

[0002] RO membrane, short for reverse osmosis membrane, is a key element in achieving reverse osmosis. It is an artificial semi-permeable membrane made to mimic biological semi-permeable membranes. It is commonly used in water treatment. After the RO membrane is manufactured into finished products, it usually needs to be packaged into individual product units. When using heat-sealing packaging, the RO membrane product is usually placed into the end of a continuously entering cylindrical packaging bag. Then, the packaging bag at both ends of the RO membrane product is heat-sealed. After heat-sealing, a cutting component is used to cut the second heat-sealed section.

[0003] Because there is a certain distance between the cutting work positions, the distance between the cutting point and the second heat sealing point of the packaging bag is relatively long, resulting in a waste of resources. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] RO membrane sealing and packaging device, including:

[0006] A heat-sealing assembly for heat-sealing continuously entering tubular packaging bags twice;

[0007] A cutting assembly for cutting the packaging bag after it has been heat-sealed twice;

[0008] A clamping assembly is used to clamp the packaging bag at the second heat-sealing position and convey it to the cutting assembly for cutting. The clamping assembly includes two clamping plates, each with a track frame at both ends. A slider fixedly connected to the clamping plate is movably inserted inside the track frame. A slide rod fixedly connected to the track frame is inserted in the middle of one slider, and a lead screw is threaded into the middle of the other slider. One end of the lead screw is connected to the output end of an external motor.

[0009] As a preferred embodiment of the above technical solution, the clamping assembly further includes two mounting brackets, the two ends of which are fixedly connected to two corresponding track brackets, and each end of the mounting bracket is provided with an inclined cylinder.

[0010] As a preferred embodiment of the above technical solution, a plurality of rollers are linearly arranged on the surface of the bottom clamping plate, the two ends of the rollers are rotatably inserted into the clamping plate, and the surface of the rollers is provided with an elastic soft layer.

[0011] As a preferred embodiment of the above technical solution, the heat sealing assembly includes two rotating shafts, and a sealing mold with a heating element is fixedly connected to one side of each rotating shaft. After the two rotating shafts drive the sealing mold to a vertical state, an external pressure application mechanism moves the two rotating shafts toward each other so that the sealing mold heat seals the packaging bag.

[0012] As a preferred embodiment of the above technical solution, the cutting component includes a cutting blade and a reciprocating drive mechanism, wherein the reciprocating drive mechanism drives the cutting blade to move back and forth in the vertical direction to cut the packaging bag.

[0013] The beneficial effects of this utility model are as follows:

[0014] The gripping assembly adopts a "double track frame + slider" structure. One side of the slider is guided by a fixed slide rod, and the other side is driven by a lead screw motor. The two gripping plates can move the packaging bag under the heat sealing assembly. It can accurately control the cutting position according to the heat sealing position, thereby reducing material waste. In addition, the gripping assembly can tilt and extend into and out of the heat sealing assembly position to avoid affecting the operation of the heat sealing assembly and the cutting assembly.

[0020] To make the objectives, technical solutions, and advantages of the present utility model embodiments clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings.

[0021] Example

[0022] Figures 1-4 The RO membrane sealing and packaging device includes:

[0023] A heat-sealing assembly for heat-sealing continuously entering tubular packaging bags twice;

[0024] A cutting assembly for cutting the packaging bag after it has been heat-sealed twice;

[0025] A clamping assembly is used to clamp the packaging bag at the second heat-sealing position and transport it to the cutting assembly for cutting. The clamping assembly includes two clamping plates 10, each with a track frame 12 at both ends. A slider 13, which is fixedly connected to the clamping plate 10, is movably inserted into the track frame 12. A slide rod 14, which is fixedly connected to the track frame 12, is inserted into the middle of one slider 13, and a lead screw 15 is threaded into the middle of the other slider 13. One end of the lead screw 15 is connected to the output end of an external motor.

[0026] The clamping assembly adopts a "double track frame 12 + slider 13" structure. One side slider 13 is guided by a fixed slide rod 14, and the other side is driven by a motor through a lead screw 15. The two clamping plates 10 can move the packaging bag under the heat sealing assembly, and can accurately control the cutting position according to the heat sealing position, thereby reducing material waste.

[0027] Figures 1-3 The clamping assembly further includes two mounting brackets 16, with each end of the mounting bracket 16 fixedly connected to two corresponding track brackets 12, and each end of the mounting bracket 16 is provided with an inclined cylinder 17.

[0028] The clamping component can be tilted and inserted between the heat sealing components to avoid affecting the operation of the heat sealing and cutting components.

[0029] Figure 4 In the process, a plurality of rollers 18 are linearly arranged on the surface of the bottom clamping plate 10. The two ends of the rollers 18 are rotatably inserted into the clamping plate 10, and the surface of the rollers 18 is provided with an elastic soft layer.

[0030] Before the clamping assembly is in operation, the roller 18 can rotate with the movement of the RO membrane product and the packaging bag, avoiding friction between the clamping plate 10 and the RO membrane product that would affect the conveying operation. When the clamping assembly is in operation, the elastic soft layer on the surface of the roller 18 contacts and deforms with the surface of another clamping plate 10, which can restrict the roller 18 and prevent unstable clamping of the packaging bag from affecting the movement and cutting of the packaging bag.

[0031] Figures 1-3 In the process, the heat sealing assembly includes two rotating shafts 21. A sealing mold 22 with a heating element is fixedly connected to one side of each rotating shaft 21. After the two rotating shafts 21 drive the sealing mold 22 to deflect to a vertical state, an external pressure application mechanism moves the two rotating shafts 21 toward each other so that the sealing mold 22 heat seals the packaging bag.

[0032] Figures 1-3In the process, the cutting component includes a cutting blade 30 and a reciprocating drive mechanism. The reciprocating drive mechanism drives the cutting blade 30 to move back and forth in the vertical direction to cut the packaging bag.

[0033] Working principle: When sealing and packaging RO membrane products, continuous cylindrical packaging bags are conveyed by the feeding system to the bottom of the heat sealing assembly. The RO membrane product to be packaged is placed inside the packaging bag. Then, the rotating shaft 21 drives the sealing mold 22 to deflect from a horizontal state to a vertical state (perpendicular to the conveying direction of the packaging bag). The external pressure mechanism pushes the two sealing molds 22 to move towards each other, completing the first heat sealing treatment of the packaging bag. The feeding system continues to convey the packaging bags containing RO membrane products, and the roller 18 rotates accordingly to avoid affecting the normal conveying of the packaging bags. After completing the second heat sealing treatment... Resetting the heat-sealing assembly allows control of the clamping assembly. Activating the tilting cylinder 17 moves the mounting frame 16 at an angle, allowing the two clamping plates 10 to enter the heat-sealing position and clamp the packaging bag at the second heat-sealing position. Multiple rollers 18 adhere to and deform against the surface of the top clamping plate 10, ensuring stable clamping of the packaging bag at the second heat-sealing position. Subsequently, the external motor drives the lead screw 15 to rotate, and the slider 13 moves accordingly, moving the clamping plates 10. The two clamping plates 10 move simultaneously, moving the packaging bag to adjust the cutting position. Finally, the reciprocating drive mechanism moves the cutting blade 30 to cut the packaging bag.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
