Description

[0002] During the production process of the material strip, the material roll needs to be replaced without stopping the machine, which requires a non-stop material changing device. The existing non-stop material changing devices are mostly used for thinner material strips. Since the traction tension required for pulling the thinner material strips is smaller, the new material strip and the old material strip are generally aligned, and then the new and old material strips are directly pasted from the top and bottom of the new and old material strips. The pasting surface is only the upper and lower surfaces. When the material strip is thicker, the traction tension required for pulling the thick material strip is larger. This material joining method cannot meet the corresponding traction force, and the interface is easy to break in the subsequent production process.

[0018] Another technical solution of the present invention is achieved in this way:

[0019] The material changing process of the cotton core material belt horizontal non-stop material changing equipment specifically includes the following steps:

[0020] S1, placing a piece of tape on the top tape pasting plate and the bottom tape pasting plate respectively, placing the new cotton core material tape on the second lifting material changing platform, and aligning the new cotton core material tape with the end surface of the second supporting plate close to the third supporting plate;

[0021] S2, after the first lifting material changing platform and the fixed material changing platform fix the old cotton core material strip, the cutting device is arranged on the end surface of the third supporting plate close to the second supporting plate, and the cutting device cuts the old cotton core material strip at the end surface of the third supporting plate, the first lifting material changing platform and the second lifting material changing platform move up, the new cotton core material strip on the second lifting material changing platform is flush with the old cotton core material strip on the fixed material changing platform, and the tape bonding gap is formed between the end surface of the new cotton core material strip and the end surface of the old cotton core material strip;

[0022] S3, the top tape pasting plate and the bottom tape pasting plate respectively paste the corresponding tape on the top and bottom of the position where the new cotton core material strip and the old cotton core material strip are to be connected, thus completing the connection of the upper and lower surfaces of the position where the new cotton core material strip and the old cotton core material strip are to be connected;

[0023] S4, the middle material receiving plate moves toward the direction close to the bottom tape pasting plate, pressing against the two tapes at the tape pasting gap, the two tapes at the tape pasting gap are pasted together, and the end faces of the new cotton core material tape and the old cotton core material tape are pasted together with the two tapes, that is, the two tapes at the tape pasting gap, the end faces of the new cotton core material tape and the end faces of the old cotton core material tape are joined together, that is, the joining of the two tapes at the tape pasting gap, the end faces of the new cotton core material tape and the end faces of the old cotton core material tape is completed;

[0024] S5, the top tape pasting plate and the bottom tape pasting plate are reset, the second lifting material changing platform and the fixed material changing platform release the fixation of the cotton core material belt, and the cotton core material belt continues to move forward after the material change, that is, the non-stop material change of the cotton core material belt is completed.

[0025] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0026] Since the horizontal non-stop material changing equipment for the cotton core material belt and its material changing process include a material changing device and a supporting device, in the process of using the equipment, the old cotton core material belt is first cut by the cutting device, and then the two tapes are respectively pasted to the positions to be connected of the new cotton core material belt and the old cotton core material belt by the material joining mechanism, and the middle material joining plate moves toward the direction close to the bottom tape pasting plate, and under the pressure of the middle material joining plate and the support of the bottom tape pasting plate, the two tapes located at the tape pasting gap are pasted together, and at the same time, the end faces of the new cotton core material belt and the end faces of the old cotton core material belt are pasted together with the tape, which is different from the existing Compared with the material joining method in which the adhesive tape is only pasted on the upper and lower surfaces of the position to be connected, in the present invention, a middle joint space is set for the material tapes, so that a tape fitting gap is formed between the ends of the aligned new cotton core material tape and the old cotton core material tape, and the two tapes and the end faces of the two cotton core material tapes at the tape fitting gap can be pasted together through the middle material connecting plate, thereby increasing the connection area of ​​the two cotton core material tapes after joining, making the joint of the cotton core material tape more firm, thereby satisfying the traction tension required for the cotton core material tape after joining, and avoiding the occurrence of disconnection at the joint of the cotton core material tape during the production process.

[0027] Since the horizontal non-stop material changing equipment for the cotton core material strip and its material changing process include a cutting device, the cutting device includes a first circular cutter and a second circular cutter. During the rotation of the first circular cutter and the second circular cutter, the cutter mounting frame moves along the Y-axis direction, and the first circular cutter and the second circular cutter cooperate to generate a shearing force on the old cotton core material strip opposite to the existing cutting device. The old cotton core material strip is cut by the shearing force. The existing cutting device cuts the strip by horizontally moving the blade. Since the cotton core material strip is soft and tough, the cotton core material strip may not be completely cut when the cotton core material strip is cut by horizontally moving the blade. In the present invention, the shearing force on the cotton core material strip during cutting is increased by cooperating with the first circular cutter and the second circular cutter, so that the cotton core material strip is fully cut, thereby solving the problem of incomplete cutting of the cotton core material strip.

[0028] Since the cotton core material belt horizontal non-stop material changing equipment and its material changing process include a cotton fluff cleaning device, the cotton fluff cleaning device includes a brush and a cotton fluff removing channel, when the first circular cutter and the second circular cutter move to the corresponding brush positions, the first circular cutter and the second circular cutter rotate, and the two brushes respectively brush off the cotton fluff wrapped around the first circular cutter and the second circular cutter, and the cotton fluff on the brushes is then adsorbed and discharged by the negative pressure of the corresponding cotton fluff removing channel, thereby realizing the cleaning of the cotton fluff wrapped around the two circular cutters and avoiding the influence of the cotton fluff on the circular cutters.

[0029] Since the horizontal non-stop material changing equipment for cotton core material strips and its material changing process include a locking assembly, and since the pull-out plate is slidably installed on the second sliding seat, a locking assembly is arranged between the pull-out plate and the second sliding seat, when it is necessary to place the tape on the bottom tape pasting plate, the pull-out plate is manually moved in a direction away from the frame, thereby increasing the operating space for placing the tape on the bottom tape pasting plate and facilitating the placement of the tape. After placing the tape, the pull-out plate is moved in a direction close to the frame, and when the limiting end face is against the second sliding seat, the ball is located in the limiting groove, that is, the pull-out plate is locked, and the pasting of the tape is not affected.
