Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electrospinning production, and particularly relates to a device for reducing the feeding and discharging loss of the base material for electrospinning. Background Art
[0002] The electrospinning coating process is an important means for preparing nanofiber composite materials. The electrospinning coating process is a preparation process in which, under the action of high-voltage static electricity, a polymer solution or melt forms a Taylor cone and a jet stream, and then, through solvent evaporation or curing, is finally deposited or combined on the surface of a receiving substrate to form a coated composite material. Since the electrospinning process can prepare fibers with diameters in the range of dozens to hundreds of nanometers, the product has a high porosity, a large specific surface area, diverse compositions, and a uniform diameter distribution, and has high application value in the filtration industry, environmental engineering, biomedicine, textiles and other fields.
[0003] In the production of the electrospinning coating process: (1) During the feeding process of the raw material, the base material has to start from the feeding starting end, pass through a series of transmission rollers, pass through the spinning area composed of one or more spinning units, and finally reach the discharging and winding end before the production program can be started; during this process, the head material of the base material between the spinning unit area and the discharging and winding end is not processed by spinning, which belongs to raw material waste, and also increases the transportation cost during the transportation process of the finished product; (2) When the production of the finished product roll is about to end, the tail material of the base material between the spinning unit area and the feeding starting end cannot be processed by spinning due to the limited traction length of the transmission rollers, resulting in raw material waste and additional cost increase (if this part is cut, the processing cost will increase, and if not cut, the transportation cost will increase). In this way, the feeding and discharging process in the production of the electrospinning coating process continuously faces problems such as raw material waste, increased transportation cost, and reduced production efficiency of winding and unwinding.
[0004] In view of the problems of feeding and discharging loss and cost waste in the production of the electrospinning coating process, currently, strong adhesive tapes are mostly used to bond the head and tail materials of two adjacent production sequences. However, due to the limited bonding strength of the tapes, the effective joining of the head and tail materials cannot be achieved, and there is a risk of disconnection due to the traction force of the transmission rollers.

[0010] Further, a clamping jaw is arranged above the front finished product coil on the installation column. Clamping plates are arranged on both movable ends of the clamping jaw. The length of the clamping plates is greater than the width of the front finished product coil.

[0023] As Figures 1 to 3 shown, a device for reducing the loading and unloading loss of the base material for electrospinning is arranged between the tail end of the front finished product coil 2 (the base material is wound on the reel) and the head end of the rear finished product coil 3. It can also be understood as being arranged between two transmission rollers 1 because the base material needs to be conveyed by the transmission rollers 1. Specifically, it includes an installation column 4. An installation crossbeam 5 is provided at the upper end of the installation column 4. One end of the installation crossbeam 5 is connected to the installation column 4. The width of the installation crossbeam 5 is greater than the widths of the front finished product coil 2 and the rear finished product coil 3. A horizontal sliding assembly is provided in the length direction of the installation crossbeam 5. A sewing mechanism 11 is provided on the horizontal sliding assembly. The sewing mechanism 11 can refer to a sewing machine in the prior art. The sewing thread of the sewing machine is cotton thread, nylon thread, or polyester fiber, etc. The diameter of the sewing thread is 0.5 - 3 mm. The sliding assembly drives the sewing mechanism 11 to slide horizontally to sew the tail end of the front finished product coil 2 and the head end of the rear finished product coil 3.
[0024] This device is mainly applied in the process of electrospinning production to optimize the material feeding process of the film-coated substrate material. The sewing mechanism 11 stitches the tail end of the front finished roll material 2 and the head end of the rear finished roll material 3, thus realizing the efficient connection of the material replacement in adjacent two production sequences, effectively, firmly and quickly connecting the tail material of the front finished roll material 2 and the head material of the rear finished roll material 3, effectively avoiding the waste of about 10 - 100 m of the raw material of the upper roll material tail and the lower roll material head, as well as the supporting spinning raw materials due to the traction length limitation of the production transmission roller 1, and saving the production cost.
[0025] In an implementable manner, the lateral sliding assembly includes a screw rod 10. The two ends of the screw rod 10 are rotatably connected to the two ends of the mounting cross beam 5. A slider 9 is provided on the screw rod 10 and is threadedly connected thereto. The sewing mechanism 11 is fixed to the slider 9. A driving motor 8 is provided at one end of the screw rod 10. The driving motor 8 is fixed to the end of the mounting cross beam 5, and the output end of the driving motor 8 is fixed to the screw rod 10. The rotation of the motor drives the sewing mechanism 11 to move laterally, so that it can perform sewing operations along the width of the substrate material.
[0026] In an implementable manner, the end of the mounting cross beam 5 is rotatably connected to the mounting column 4, and a support rod 6 is provided on the side of the mounting column 4. One end of the support rod 6 is rotatably connected to the mounting column 4, and a limit pin 7 is provided at the other end of the support rod 6. The limit pin 7 connects the other end of the support rod 6 to the mounting cross beam 5. The advantage of the rotational connection is that the mounting cross beam 5 can be rotated to the outside by rotation to avoid interference with the installation and replacement of the rear finished roll material 3. At the same time, the limit pin 7 connects the support rod 6 to the mounting cross beam 5, which can lock the rotation of the mounting cross beam 5 to avoid rotation problems during sewing.
[0027] In an implementable manner, a clamping jaw 13 is provided above the front finished roll material 2 on the mounting column 4. The clamping jaw 13 is a prior art and can be understood as a clamping cylinder. Clamping plates 12 are provided on both movable ends of the clamping jaw 13. The length of the clamping plates 12 is greater than the width of the front finished roll material 2. The clamping plates 12 are used to clamp the tail end of the front finished roll material 2 and the head end of the rear finished roll material 3. By clamping with the clamping plates 12, the tail end of the front finished roll material and the head end of the rear finished roll material 3 can be clamped together without manual fitting, improving the sewing efficiency.
[0028] In an implementable manner, a mounting seat connected to the ground is provided at the other end of the mounting column 4. A roller and a counterweight are provided on the mounting seat, facilitating the movement and installation of this device.
[0029] In an implementable manner, sponge layers are provided on the opposite sides of the two clamping plates 12, which not only improves the clamping friction but also avoids clamping damage to the substrate material.
