[0002] Hemodialyzer is mainly composed of membrane bundle, shell, sealing layer and end cap, etc., which is widely used in the treatment of uremia patients. Among them, the membrane bundle is composed of a plurality of hollow fiber membranes and membrane paper. In the forming process of the membrane bundle, first, the membrane filaments are collected by a filament collecting device, then the collected membrane filaments are wrapped into a cylindrical membrane bundle with the membrane paper, and then the membrane paper is fixed with transparent tape. Finally, it is cut to a specified size.
[0003] Currently, in the process of fixing the membrane paper with transparent tape, most of them use manual method, that is, the cut tape paper is manually adhered and fixed along the outer circle of the membrane bundle. Patent CN114249166A discloses a kind of film bundle automatic tape sticking device and its tape sticking method, although it can replace manual operation to cut and adhere the tape paper to the joint of the membrane paper along the outer circle of the membrane bundle, but the device uses a tape sticking wheel in the process of adhering the tape paper, which requires high coordination between the action of the tape sticking wheel and other mechanisms. Specifically, through the rotation of the tape sticking wheel, one side of the polygon corresponds to the notch of the left and right wrapping arms of the wrapping device. Under the action of the cylinder and guide shaft of the transfer mechanism, the two tape mechanisms complete a sticking action on the membrane bundle in the radial direction of the outer circle of the membrane bundle. The tape paper cut and attached to the silicone plate by the tape sticking wheel is adhered to the joint of the membrane paper. The above design requires high precision, and any slight mistake will affect the adhesion quality of the tape paper and reduce the pass rate. UTILITY MODEL CONTENTS
[0004] To solve the above problems, the utility model provides a kind of film bundle automatic tape sticking device, simple structure, reliable operation, high practicability.
[0005] The utility model adopts the following technical solutions:

[0007] Preferably, the tape cutting mechanism employs two identical components symmetrically distributed. One component consists of a tape roll mounted on a pulley, with the tape paper at the output end of the tape roll clamped by a traction gripper. A guide wheel is positioned between the pulley and the traction gripper, flush with the traction gripper to ensure the pulled-out tape paper is horizontal. The traction gripper is driven by an electric cylinder. A vertically positioned positioning cylinder is located above the guide wheel, with its lower pressure block facing the guide wheel.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0019] like Figure 1 As shown, the membrane filaments 101 are wrapped into a bundle by the membrane paper 102. The seams of the membrane paper need to be fixed with adhesive tape 103 along the outer circle direction. A bundle of membranes is fixed with a number of adhesive tapes with consistent spacing to facilitate subsequent processing into segments.
[0020] like Figure 2 , Figure 3 As shown, in order to achieve Figure 1 The state of the membrane bundle being pasted with adhesive tape is shown. The device provided by this utility model mainly consists of a tape cutting mechanism 2, a tape pasting mechanism 3, a tape pressing mechanism 4, and a transverse movement mechanism 5.
[0021] like Figure 4 As shown, the tape cutting mechanism 2 consists of two symmetrically distributed components. Two tape rolls are respectively mounted on tape pulleys 201 on both sides, with the adhesive side of the tape 202 facing upwards. The traction grippers 205 on both sides clamp one end of the tape 202. Under the action of the electric cylinder 207, the tape 202 on both sides is pulled out from the tape rolls through the guide wheel 203. The pressure blocks of the positioning cylinders 206 on both sides press the tape 202 onto the guide wheel 203. The cutting cylinder drives the blades 204 on both sides to extend and cut the tape 202 to form adhesive tape 10301 and adhesive tape 10302. The fingers of the traction gripper 205, the pressure blocks of the positioning cylinder 206, the guide wheel 203 and the blades 204 are all made of Teflon material, so that the tape does not easily stick to them. The belt pulley 201 generates a certain amount of damping under the action of the compression spring, preventing the tape 202 from becoming slack after being pulled out.
[0022] like Figure 5As shown, the tape-applying mechanism 3 mainly consists of two sets of symmetrically distributed tape-applying cylinders 301 and suction nozzles 302. A dual-axis motor drives the tape-applying cylinders 301 on both sides to rotate. When the tape-cutting mechanism 2 pulls out the tape 202, the dual-axis motor drives the tape-applying cylinders 301 to rotate, so that the suction nozzles 302 on the tape-applying cylinders 301 are directly below the tape 202. At this time, the tape-applying cylinders 301 extend, and the suction nozzles 302 generate a vacuum under the action of the vacuum generator and suck up the tape 202. After the blade 204 cuts the tape 202, the dual-axis motor drives the suction nozzles 302 to rotate to the membrane bundle bonding position. The cut adhesive tape 10301 and adhesive tape 10302 are bonded to the membrane bundle 1 under the action of the extension of the tape-applying cylinders 301.
[0023] like Figure 6 As shown, after the tape-applying mechanism 3 applies the adhesive tape 10301 and adhesive tape 10302 to the membrane bundle 1, the tape pressing mechanism 4 needs to press the applied tape firmly to prevent the edges of the tape 103 from not adhering to the membrane bundle 1. The adjustable-stroke pressing cylinder 401 drives the pressing block 402 to press the adhesive tape 10301 and adhesive tape 10302 firmly.
[0024] The transverse movement mechanism 5 mainly consists of a linear module and guide rails. When the transverse movement mechanism 5 operates, it carries the tape cutting mechanism 2 and the tape applying mechanism 3 to apply tape to the next segment of the membrane bundle, while the tape pressing mechanism 4 presses the tape paper being applied.
[0025] In summary, such as Figures 1 to 6 As shown, the membrane bundle is placed in a straight line, and the device of this utility model is located at the beginning of the membrane bundle; two tape rolls are respectively installed on the tape rollers 201 on both sides, with the adhesive side of the tape 202 facing upward. By adjusting the compression amount of the compression spring, the tape rollers 201 are rotated under a certain damping to achieve a tight state of tape 202 extending out; the dual-output shaft motor drives the tape-applying cylinder 301 to rotate so that the suction nozzle 302 is located directly below the tape 202;
[0026] The two traction grippers 205 on both sides clamp one end of the adhesive tape 202. When the electric cylinder 207 is activated, the adhesive tape 202 clamped on both sides is pulled out from the tape roll through the guide wheel 203. The positioning cylinders 206 on both sides press the adhesive tape 202 onto the guide wheel 203. At the same time, the tape-applying cylinder 301 extends, and the suction nozzle 302, under the action of the vacuum generator, sucks up the adhesive tape 202. The cutting cylinder drives the blades 204 on both sides to extend and cut the adhesive tape 202, forming the adhesive tape 10301 and the adhesive tape 1. 0302; The traction gripper 205 opens, the electric cylinder 207 actuates, the traction gripper 205 moves forward, and the fingers of the traction gripper 205 avoid the adhesive tape; at this time, the adhesive tape 10301 and adhesive tape 10302 have been adsorbed onto the suction nozzle 302, the adhesive tape cylinder 301 retracts, the dual output shaft motor drives the adhesive tape cylinder 301 to rotate to the adhesive position of the membrane bundle, the adhesive tape cylinder 301 extends, and the adhesive tape 10301 and adhesive tape 10302 adsorbed on the suction nozzle 302 are adhered to the beginning of the membrane bundle;
[0027] Driven by the linear module of the transverse mechanism 5, the tape cutting mechanism 2 and the tape applying mechanism 3 move forward and repeat the above actions to apply the adhesive tape 10303 and adhesive tape 10304 to the next segment of the membrane bundle; the tape pressing mechanism 4 moves to the application position of the current membrane bundle, the pressing cylinder 401 extends, and the pressing block 402 presses the adhesive tape 10301 and adhesive tape 10302 firmly, thereby completing the tape application action.
[0028] The transverse mechanism 5 drives the device of this utility model to sequentially complete the pasting actions of pasting tape 10301, pasting tape 10302, pasting tape 10303, pasting tape 10304, pasting tape 10305, pasting tape 10306, etc., and finally complete the pasting of the entire membrane bundle 1.
