Description

Technical Field

[0001] The utility model relates to the technical field of ribbon processing, in particular to a melting and cutting machine for improving the edge sealing thickness of a ribbon base. Background Art

[0002] The ribbon is a ribbon fabric woven with nylon filaments as raw materials. It is made after melt cutting and ink coating and absorption. It is generally cut by a melt cutting machine and inked by an inking machine.

[0003] Chinese patent CN210500544U discloses a ribbon fusing machine, which includes a frame, a winding mechanism, a fusing assembly, a ribbon conveying assembly and a transmission assembly; the upper and lower ends of the frame are respectively provided with a main shaft and a unwinding roller; the winding mechanism includes a rotating shaft, a supporting frame and a winding shaft; the fusing assembly includes a knife shaft and a fusing mechanism; the ribbon conveying assembly includes a conveying roller and a driving device; the unwinding roller unwinds the ribbon base cloth and then transmits it to the knife shaft through the transmission assembly, and the ribbon base cloth is fusing-cut by the high temperature generated by the fusing knife of the fusing mechanism, and after the fusing is completed, the driving device provides power to drive the conveying roller to cooperate with the main shaft to make the surface of the ribbon base after the fusing is more flat and smooth, and increase the friction between the ribbon base cloth and the main shaft so that the winding stability of the ribbon base obtained after the fusing is better; the fusing device has a simple structure and is easy to operate, and improves the quality of the ribbon base after the fusing.

[0004] However, due to the direct contact between the melting blade and the melting blade shaft, the height of the melting blade will continue to decrease due to wear. The height change of the melting blade will cause the contact position and contact length between the melting blade and the melting blade shaft to change. The nylon component in the ribbon base has a longer contact length with the melting blade, so the thickness of the ribbon base edge crystal formed after the nylon fiber is instantly melted increases. Although such a melting process can still ensure the edge sealing strength of the ribbon base, the thickness of the edge sealing exceeds 20% to 30% of the thickness of the ribbon base, which can easily cause the ribbon base to be squeezed by the inking roller in the later inking process, resulting in the phenomenon of ribbon edge breakage and delamination, affecting the performance and service life of the product.

[0005] At the same time, the method originally used after the height of the melting cutting blade is lowered is to increase the tension of the tension spring of the melting cutting blade to control the contact point between the melting cutting blade and the melting cutting blade shaft. However, as the height of the melting cutting blade becomes lower and lower, the increasing tension of the tension spring will cause the cutting blade to exert greater pressure on the melting cutting blade shaft, which will not only increase the degree of wear between them and affect the service life of the melting cutting blade shaft and the blade, but also cause quality problems such as burrs and coarse particles in the melting cutting process. Utility Model Content

[0006] The purpose of the utility model is to address the shortcomings of the prior art and provide a melting and cutting machine for improving the thickness of the base edge of a ribbon. The function of keeping the contact length between the melting and cutting blade and the hanging knife shaft unchanged is achieved by moving the hanging knife shaft up and down in coordination with the melting and cutting blade, thereby solving the problem in the prior art that the change in contact position and contact length between the two leads to an increase in the thickness of the crystals at the edge of the ribbon base formed after the ribbon edge is melted.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0013] Preferably, an elastic member is provided between the limiting seat and the melting cutting blade, and the melting cutting blade and the elastic member are provided in a one-to-one correspondence.

[0014] Preferably, a supporting assembly is provided at the bottom end of the limiting seat.

[0015] Preferably, the support assembly includes: a lifting member arranged below the limit seat and a top plate arranged between the limit seat and the frame.

[0016] Preferably, the fusion cutting blade is movably connected to the blade hanging shaft.

[0017] Preferably, the melting cutting blade is provided with a mounting groove matched with the blade hanging shaft.

[0018] The beneficial effects of the utility model are:

[0034] Example

[0035] like Figure 1-8As shown, this embodiment provides a melting and cutting machine for improving the edge sealing thickness of a ribbon base, which is generally suitable for other products suitable for melting and cutting processing such as edge sealing of a ribbon base, including: a frame 1, a melting and cutting roller 2 arranged on the frame 1, and a cutting blade assembly 3 arranged below the melting and cutting roller 2, wherein the cutting blade assembly 3 includes: a hanging knife shaft 31 and a plurality of melting and cutting blades 32 arranged on the hanging knife shaft 31, wherein the cutting edges of the melting and cutting blades 32 are pressed against the melting and cutting roller 2 to melt and cut the ribbon on the melting and cutting roller 2, and the machine is characterized in that it also includes a device for controlling the hanging knife shaft 31 to move along the frame 1. The control component 13 reciprocates in the vertical direction to change the distance between the melting blade 32 and the melting roller 2. The upper and lower positions of the melting roller 2 are adjusted by the control component 13. The operation is simple and easy to use. The contact length between the melting blade 32 and the knife hanging shaft 31 remains unchanged, which reduces the wear of the melting blade 32 and increases its service life. It also reduces burrs and coarse particles generated during the melting process, thereby reducing the number of melted crystals on the ribbon base edge seal, and does not increase the thickness of the ribbon base edge seal, thereby ensuring the processing quality of the ribbon base edge seal.

[0036] The control assembly 13 comprises a slide groove 131 provided on both sides of the frame 1, and the two ends of the knife hanging shaft 31 are slidably arranged in the slide groove 131; an adjustment assembly 132 for adjusting the position of the knife hanging shaft 31; a positioning member 133 for positioning the position of the knife hanging shaft 31, and the positioning member 133 is fixedly connected to the knife hanging shaft 31; and a fastener 134, the fastener 134 connects the positioning member 133 with the frame 1, so that the melting blade 32 on the knife hanging shaft 31 can be in the optimal processing position, which can not only ensure the processing efficiency of the ribbon base edge sealing, but also make full use of the melting blade 32 to extend its service life. That is, the upper and lower positions of the knife hanging shaft 31 can be adjusted in time according to the change in height of the melting blade 32 during use, to ensure that the contact length between the melting blade 32 and the knife hanging shaft 31 remains unchanged, and the whole process is simple to operate and easy to use.

[0037] At the same time, the adjustment component 132 includes: a fixing seat 1321 fixedly connected to the bottom of the positioning member 133 and a screw 1322 passing through the fixing seat 1321 and abutting against the bottom end of the positioning member 133. The positioning member 133 is driven to move up and down reciprocatingly by rotating the screw 1322 to correspond to the adjustment of the position of the melting blade 32. It has a simple structure and is easy to disassemble and assemble.

[0038] In this embodiment, the control component 13 also includes an identification scale arranged on the adjacent side of the slide groove 131 for displaying the height position of the hanging knife shaft 31. The position identification scale 14 is used to accurately observe the position of the melting blade 32, so that corresponding adjustments can be made according to the actual damage of the melting blade 32. Specifically, it is preferred that the general height of the melting blade 32 is about millimeters and the service life is about two years. Then, four control points are set according to the service life of the melting blade 32 of about two years, that is, four position identification scales 14 are arranged on one side of the slide groove 131. Under the premise that the elastic member 12 can be used for fine adjustment without affecting the blade pressure of the melting blade 32, the hanging knife shaft 31 is adjusted downward once every six months. In this way, during the production process of the melting machine, the upper and lower positions of the hanging knife shaft 31 can be adjusted according to the decrease in the height of the melting blade 32, so as to achieve the effect that although the height of the melting blade 32 decreases, the contact part and length with the hanging knife shaft 31 remain unchanged.

[0039] In this embodiment, it also includes a limit seat 11 slidably arranged on the frame 1, and the limit seat 11 moves synchronously with the knife hanging shaft 31, and preferably a connecting member 16 is provided between the limit seat 11 and the positioning member 133, so that the movement state of the limit seat 11 and the knife hanging shaft 31 are consistent, that is, they move synchronously, so as to ensure that although the height of the melting blade 32 is reduced, the contact position and length with the knife hanging shaft 31 remain unchanged, so that the force of the tension spring acting on the melting roller 2 remains unchanged, thereby ensuring the stability of the melting blade 32.

[0040] In this embodiment, an elastic member 12 is provided between the limit seat 11 and the melting blade 32. The melting blade 32 and the elastic member 12 are provided in a one-to-one correspondence, ensuring that the melting blade 32 decreases in height while the contact position and length with the knife hanging shaft 31 remain unchanged. The elastic member 12 is preferably a tension spring. The tension spring has strong resilience after being deformed by force and can quickly return to its original state. Moreover, its elastic force is stable and easy to use.

[0041] In this embodiment, a support assembly 15 is provided at the bottom end of the limit seat 11, and the support assembly 15 is used to support the limit seat 11 to move up and down, so that the limit seat 11 can be quickly moved to a specified position, saving time and thus improving work efficiency.

[0042] In this embodiment, the support assembly 15 includes: a lifting member 151 arranged below the limit seat 11 and a top plate 152 arranged between the limit seat 11 and the frame 1. The lifting member 151 is preferably a cylinder, which drives the top plate 152 to move up and down reciprocatingly. It is simple to operate and easy to control. The top plate 152 increases the contact area between the output end of the cylinder and the limit seat 11, that is, it increases the force area of ​​the lifting member 151, thereby making the limit seat 11 more stable when moving up and down.

[0043] Of course, the fusion cutting blade 32 is movably connected to the hanging knife shaft 31, and the fusion cutting blade 32 is provided with a mounting groove 321 adapted to the hanging knife shaft 31. The size of the mounting groove 321 should be larger than the diameter of the hanging knife shaft 31, that is, the hanging knife shaft 31 can move in the mounting groove 321 or the fusion cutting blade 32 can rotate on the hanging knife shaft 31, and then the fusion cutting blade 32 is adjusted to the optimal processing position by the elastic member 12 to ensure that the contact length between the fusion cutting blade 32 and the hanging knife shaft 31 remains unchanged, so that the processed product will not deviate, thereby ensuring the performance of the product, and the contact area between the cutting part of the fusion cutting blade 32 and the ribbon is small, which can reduce burrs and coarse particles that appear during the edge banding processing of the ribbon base.

[0044] In addition, the upper and lower positions of the knife shaft 31 are adjusted in time according to the decrease in the height of the melting blade 32. Such adjustment of the melting process ensures that the edge sealing strength of the ribbon base after the melting is completed also meets the quality standards, and the edge thickness of the ribbon base will not increase due to the decrease in the height of the melting blade 32. The stability of the thickness of the edge of the ribbon base is of great help to the subsequent inking production. It can avoid the glass-like crystals at the edge of the ribbon base due to the pressure of the ink pressing roller and the occurrence of debonding, and the double-sided inking method can be used to speed up the ink penetration and improve product turnover. The improvement of the melting process ensures the stability of product quality, improves production efficiency and provides customers with better services.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
