Description

Technical Field

[0001] The invention relates to the technical field of glass fiber cloth preparation, in particular to a static electricity elimination device in the twisting process of glass fiber twisting. Background Art

[0002] In the production process of glass fiber cloth, the twisting of the bobbin yarn is the intermediate link after the glass fiber is drawn and before the cloth is woven. After the glass fiber raw material is melted at high temperature and drawn into fiber filaments, the fiber filaments are twisted by the twisting bobbin yarn before they can be used for weaving. The twisting of the twisting bobbin yarn is a key link that is of vital importance.

[0003] When twisting, the nylon hook and the steel collar will inevitably have continuous and frequent friction, and the yarns will also have friction with each other. This friction condition is very likely to cause static electricity, and once static electricity is generated and accumulated to a certain extent, it will have many adverse effects on the entire twisting process, such as uneven winding of the yarn, knotting, and even affecting the strength and quality stability of the yarn, thereby reducing the quality of the finished glass fiber cloth.

[0004] In the actual operation of the twisting machine, due to the unique process characteristics of the yarn cake itself, there are relatively clear requirements for the temperature and humidity of the production environment, which need to be maintained within a specific range. However, in actual production scenarios, dry environmental conditions often occur, which is extremely unfavorable for the elimination of static electricity, seriously affecting the production efficiency of glass fiber cloth and the stability of product quality.

[0005] Therefore, a kind of static elimination device of glass fiber twisting process is badly needed. Summary of the invention

[0006] The object of the present invention is to provide a static eliminator for a glass fiber twisting process, which can solve the above-mentioned problem, reduce static electricity in the glass fiber twisting process, and ensure the strength and quality stability of the yarn.

[0007] The invention provides a static elimination device for a glass fiber twisting process, comprising a horizontally arranged machine platform, on which are arranged a plurality of groups of vertically arranged bobbins, partitions are arranged between adjacent bobbins, and on the partitions are static elimination rods parallel to the bobbins axis.

[0008] Preferably, the static elimination bars correspond to the cops one by one.

[0009] Preferably, the distance between each of the static elimination bars and the corresponding bobbin is the same.

[0010] Preferably, the height of the static elimination bar is greater than the height of the bobbin.

[0011] Preferably, a through hole is provided on the machine platform, and a wire at the bottom of the static elimination rod passes through the through hole to connect to a power source.

[0012] Preferably, a working indicator light is provided at the top of the static elimination bar. When the static elimination bar works normally, the working indicator light is green, and when the static elimination bar works abnormally, the working indicator light is red.

[0013] Preferably, the static elimination bar comprises a high voltage power generator, the high voltage power generator is connected to discharge needles, and the discharge needles are arranged linearly on the static elimination bar.

[0014] Preferably, the discharge needle is arranged along the radial direction of the cop.

[0015] Preferably, the static elimination rod is an ion wind rod.

[0016] Preferably, the outer wall of the static elimination bar is connected to the partition bolts through an L-shaped bracket.

[0017] Beneficial effects:

[0018] The present invention effectively neutralizes the static electricity generated during the twisting process of the bobbin by arranging a static elimination rod parallel to the bobbin, thereby avoiding excessive static electricity, providing an effective guarantee for improving the efficiency of the twisting machine and improving the quality of the glass fiber bobbin. The static elimination rod corresponds to the bobbin one by one, and its height is greater than the height of the bobbin, which can fully cover the working area of ​​the bobbin and eliminate static electricity in all directions as the bobbin rotates.

[0026] Example 1

[0027] like Figure 1 As shown, a static elimination device for the twisting process of glass fiber twisting includes a horizontally arranged machine table 6, on which are arranged a plurality of groups of vertically arranged bobbins 4, and between adjacent bobbins 4, a partition 1 is arranged, one side of the partition 1 is close to the frame, and the other side is located at the front end of the machine table 6, and an opening is formed between adjacent partitions 1, so that the staff can observe the status of the bobbins 4, and the partitions 1 are all provided with static elimination rods 2 parallel to the axis of the bobbins 4. The static elimination rods 2 are arranged at the front end of the partition 1, so that the staff can install, clean, replace, etc. the static elimination rods 2.

[0028] The static elimination rod 2 corresponds to the cop 4 one by one, so that a problem with one static elimination rod 2 will not cause abnormal static electricity in multiple cops 4. The distance between each static elimination rod 2 and the corresponding cop 4 is the same, ensuring a stable static elimination effect and avoiding a large difference in static elimination effect between different cops 4, which will lead to unstable yarn quality. The height of the static elimination rod 2 is greater than the height of the cop 4, and the static elimination rod 2 is sufficient to cover the entire height area of ​​the cop 4, so that all-round static elimination can be achieved when the cop 4 rotates.

[0029] A through hole 8 is provided on the machine platform 6, and a wire 7 at the bottom of the static elimination rod 2 passes through the through hole 8 to connect to a power source 9. The wire 7 is a shielded high-voltage wire 7, which has high safety.

[0030] A working indicator light 10 is provided at the top of the static eliminator 2. When the static eliminator 2 works normally, the working indicator light 10 lights up green, and when the static eliminator 2 works abnormally, the working indicator light 10 lights up red. The staff can find abnormalities in time during inspection and repair the abnormal static eliminator 2.

[0031] The static elimination rod 2 is electrically connected to the electric control system of the twisting machine to ensure that the static elimination rod 2 and the bobbin 4 are twisted synchronously to achieve static elimination in the whole process. The static elimination rod 2 adopts an ion wind rod.

[0032] The static elimination rod 2 includes a generator, which is composed of a high-voltage power supply 9 generator and a discharge needle. The high-voltage power supply 9 generator is connected to the discharge needle. The air is ionized into a large number of positive and negative ions through high-voltage corona discharge at the tip of the discharge needle. The discharge needle is arranged linearly on the static elimination rod 2. The ion wind rod can use wind to blow a large number of positive and negative ions to the surface of the cop 4 to neutralize static electricity, and static elimination can be completed without approaching the cop 4. The discharge needle is arranged along the radial direction of the cop 4, and the discharge end of the discharge needle is directly facing the cop 4.

[0033] The outer wall of the static elimination rod 2 is bolted to the partition 1 through the L-shaped bracket 3, and a fixed installation is adopted. There is no need to set a power device to move the distance between the static elimination rod 2 and the tube yarn 4. The overall structure is simpler and the service life is extended.

[0034] Working principle:

[0035] The static elimination rod 2 is installed vertically at the front end of the partition 1, and is bolted to the partition 1 with an L-shaped bracket 3. The discharge needle of the static elimination rod 2 faces the bobbin 4 to ensure the static elimination effect to the greatest extent. When the bobbin 4 rotates, the static elimination rod 2 can eliminate static electricity in all directions.

[0036] The original static elimination adopts the static elimination rod 2 connected with the steel collar plate 5, and the static elimination is performed as the steel collar plate 5 is raised and lowered.

[0037] The static elimination effects of the static elimination device of the prior art and the static elimination device of the present invention were tested. Under the prior art, the static value was 0.18KV; after the static elimination device of the present invention was working, the static value was measured to be 0.08KV. It can be seen that the static elimination effect of the static elimination device of the present invention is significantly improved, and the static electricity generated in the production process can be greatly reduced.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
