[0028] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1-2 As shown, an industrial RO membrane automatic film rolling machine includes a machine body 1, and a feeding device 2 for placing RO membrane rolls and a RO membrane rolling device 4 for rolling a central tube 6 are respectively provided on both sides of the machine body 1, and a transmission channel 3 for RO unfolding is provided between the feeding device 2 and the RO membrane rolling device 4, and a glue-applying device 5 is provided above the transmission channel 3. The feeding device 2 is used to install the RO membrane roll, and the RO membrane roll can rotate on the outgoing device. The area where the RO membrane roll is installed on the feeding device 2 corresponds to the area of ​​the central tube 6 on the RO membrane rolling device 4, so that the RO membrane can be horizontally unfolded on the transmission channel 3 without wrinkles. Shielding structures or laser markings can be provided on both sides of the transmission channel 3 to align the feeding device 2 with the RO membrane rolling device 4 to ensure the straight and flat laying of the RO membrane.

[0030] The RO membrane rolling device 4 includes a central tube frame 7 for horizontally supporting the central tube 6. The central tube frame 7 includes a left frame and a right frame respectively arranged on both sides of the central tube 6. The left frame and the right frame are both perpendicular to the central tube 6. The top of the left frame and the right frame is provided with a horizontally arranged top frame.

[0031] like Figure 3 As shown, a driving device 8 and a rotating support device 9 are respectively provided on both sides of the central pipe frame 7. For example, a driving device 8 is provided on the outer side of the right frame, and a rotating support device 9 is provided on the outer side of the left frame.

[0032] The rotating driving end of the driving device 8 is fixedly connected to one end of the central tube 6, and can be fixed by a detachable connecting piece, which is convenient for the disassembly and assembly of the central tube 6, and is used to control the rotation speed and rotation direction of the central tube 6. Specifically, the driving device 8 includes a driving motor 10, a reducer 11 and a first central tube connector 12. The driving motor 10 is connected to the central tube 6 connector through the reducer 11. The reducer 11 includes a small pulley and a large pulley. The driving end of the driving motor 10 is connected to the small pulley. The first central tube connector 12 is fixedly connected to the large pulley. The small pulley and the large pulley are driven by a conveyor belt, so that the driving motor 10 controls the rotation of the first central tube connector 12 after deceleration. The first central tube connector 12 is connected to the central tube frame 7 through a bearing. The first central tube connector 12 is respectively connected to the reducer 11 and the central tube frame 7 to achieve two-point support, thereby ensuring the installation stability of the first central tube connector 12. The connecting end of the first center tube connector 12 is fixedly connected to the center tube 6, and the connecting end is provided with a detachable tube connector 13, or the end of the center tube 6 is a polygonal structure, and the insertion hole of the first center tube connector 12 is a matching polygonal hole; the first center tube connector 12 is also provided with a clamping head for clamping the end of the main center tube 6. When the center tube 6 is installed to the first center tube connector 12, the clamping head is used to clamp the main center tube 6.

[0033] like Figure 4 As shown, the rotating support device 9 abuts against the other end of the central tube 6 when the central tube 6 rotates, so as to balance the rotation force of the central tube 6 and facilitate the disassembly and assembly of the central tube 6. When the central tube 6 needs to be disassembled or installed, the rotating support device 9 is separated from the central tube 6, and a space is reserved for the central tube 6 to be pulled out from the driving device 8. Specifically, the rotating support device 9 includes a linear driving member 14 and a second central tube connector 15. The linear driving member 14 is rotatably connected to the central tube 6 through the second central tube connector 15. The connecting end of the second central tube connector 15 is provided with a sleeve structure for inserting the end of the central tube 6.

[0034] The second central tube connector 15 rotates synchronously with the central tube 6, including the following two methods:

[0035] 1. The second central tube connector 15 is provided with bearings, and the number of bearings is preferably 2-3. Multiple bearings are used as support points, which can play a very stable limiting role for the second central tube connector 15. The bearings are fixedly connected to the moving end of the linear drive 14 through the bearing frame 16, that is, the bearing frame 16 is fixedly connected to the second central tube connector 15 through the bearings. Since the bearing frame 16 needs to cover and fix the bearings, and the second central tube connector 15 will vibrate during the rotation process, in order to improve the stability of the structure, the frame is provided with a guide rod 17 for guiding the linear motion of the second central tube connector 15, and the guide rod 17 is parallel to the feeding direction of the second central tube connector 15.

[0036] 2. The second center tube connector 15 is embedded with a rotating sleeve 18 for inserting the end of the center tube 6. The rotating sleeve 18 and the second center tube connector 15 are embedded in an embedded rotating connection. The rotating sleeve 18 is embedded in the interior of the second center tube connector 15. This structure enables the second center tube connector 15 to be fixedly connected to the moving end of the linear drive member 14. Since the second center tube connector 15 does not rotate, the force it receives is relatively stable, and there is no need to set up a guide rod 17 separately.

[0037] The central tube frame 7 is provided with an auxiliary roller 17 parallel to the central tube 6, and a feeding device 18 for driving the auxiliary roller 17 to be close to the central tube 6. The auxiliary roller 17 is arranged at any position around the central tube 6. When the central tube 6 rotates to roll the RO membrane, the auxiliary roller 17 presses the central tube 6 and rotates in the opposite direction with the rotation of the central tube 6, which is used to press the RO membrane against the central tube 6 to prevent a large gap or bubble between the rolled RO membrane and the central tube 6, so as to ensure the rolling quality of the RO membrane. The feeding device 18 includes a feeding member arranged on the central tube frame 7 and symmetrically arranged on both sides of the auxiliary roller 17. In this embodiment, the feeding member is a cylinder perpendicular to the central tube 6, and the feeding direction of the cylinder is toward the central tube 6, which is used to make the feeding direction of the feeding member perpendicular to the central tube 6, so that the auxiliary roller 17 can be closely and fully fitted to the central tube 6.

[0038] The glue-spraying device 5 is provided with a three-axis mechanical arm, the first axis 19 of the three-axis mechanical arm is parallel to the conveying channel 3 and is arranged on one side of the conveying channel 3, the second axis 20 is horizontally perpendicular to the conveying channel 3 and is located above the conveying channel 3, the third axis 21 is vertically perpendicular to the conveying channel 3 and is located above the conveying channel 3, and the mobile terminal of the three-axis mechanical arm is provided with a glue-spraying head 22. The cooperation between the three axes in the three-axis mechanical arm realizes the spatial movement of the glue-spraying head in front and back, left and right, and up and down, so as to meet the demand of glue-spraying the edge of the unfolded RO membrane.

[0039] like Figure 5As shown, the machine body 1 is provided with an automatic cutter device 23, which includes a cutter 24, a horizontal driving member 25 for driving the cutter 24 to move horizontally, and a lifter 26 for driving the horizontal driving member 25 to move up and down, and the fixed end of the lifter 26 is fixedly connected to the machine body 1. The horizontal driving member 25 is parallel to the central tube 6, so that the cutter 24 can horizontally cross the RO membrane and cut the RO membrane. The horizontal driving member 25 is provided with a slide rail, and the sliding end of the slide rail is provided with a vertically upward cutter 24. The main body of the slide rail is fixed to the machine body 1 and is located on the inner side of the central tube frame 7. Alternatively, in order to prevent the horizontal driving member 25 from affecting the movement of the RO membrane, the horizontal driving member 25 is set on a lifter 26, and the lifter 26 can be a cylinder or a screw. The fixed end of the lifter 26 is fixed to the machine body 1, and the lifting end of the lifter 26 is fixedly connected to the horizontal driving member 25. The horizontal driving member 25 is also provided with detection contacts, such as electrical contacts, force contacts, etc., for detecting whether the cutter 24 has reached both ends, so as to detect whether the cutter 24 has passed through the entire RO membrane and realize the cutting of the RO membrane.

[0040] like Figure 6 As shown, the machine body 1 is provided with a tape wrapping device 27, which includes a tape holder 28 for a safety tape, and the tape holder 28 is rotatably connected to the machine body 1. An auxiliary holder 29 is provided between the tape holder 28 and the central tube 6. When the tape is not in use, the tape head is pasted on the auxiliary holder 29 for direct use when it is reused. A dustproof shell is provided around the auxiliary holder 29 to prevent external dust from contaminating the tape. Working principle of the tape wrapping device 27: After the RO membrane is rolled, the tape device will work to the specified position, wait for the adhesive to be attached to the element, and then move in a uniform reverse linear motion until the entire membrane roll is completed.

[0041] This technology is an industrial RO membrane automatic film rolling machine working process:

[0042] 1. Fix one end of the central tube to the drive device;

[0043] 2. Install the cloth guide roll onto the discharging device;

[0044] 3. Open the cloth guide roll, lay the cloth guide flat along the conveying channel and stick it to the center tube;

[0045] 4. Place the stacked RO diaphragms on the flat guide cloth, and then edit the PC. The PC is used to control the working trajectory of the three-axis motion. For example, you can edit all the routes on the PC to drive the three-axis motion according to what kind of glue path you want to make.

[0046] 5. The dispensing device dispenses glue along the edge of the flat RO membrane under the control of the three-axis robotic arm;

[0047] 6. Repeat steps 4-5, and finally place another layer of flat guide cloth, and the glue dispensing device dispenses glue along the edge of the guide cloth;

[0048] 7. Start the rotating support device to press the center tube;

[0049] 8. Start the drive device to rewind. After rewinding, start the cutter device to automatically cut the guide cloth;

[0050] 9. The tape wrapping device automatically applies the tape, and the tape is cut and unloaded manually.

[0051] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
