Description

Technical Field

[0001] The utility model relates to the technical field of gear modification of a TMT texturizing machine oil tanker, and in particular to a driving device which is convenient for switching the rotation speed of the TMT texturizing machine oil tanker. Background Art

[0002] The texturing machine is a key equipment in the post-processing of polyester filaments, and the oil tanker plays a pivotal role in it. The main function of the oil tanker is to oil the yarn bundle, which significantly reduces friction. This measure can greatly reduce the friction between the textured yarn and the equipment during the processing, making the yarn bundle run more smoothly. This plays an important role in improving the softness, cohesion and other key properties of the textured yarn, and also creates more favorable conditions for subsequent processing links, especially weaving and other processes.

[0003] At present, the mechanism used to drive the speed of the oil tanker in the TMT texturing machine includes a motor, a driving gear driven by the motor, a driven gear coaxially connected to the oil tanker, and a chain. One of the gears is a frequency conversion gear. The speed control of the oil tanker depends on the size change of one of the frequency conversion gears, thereby determining the speed of the oil tanker and the specific situation of oiling. However, simply setting the frequency conversion gear to the maximum or minimum value is often difficult to meet the actual requirements of the process. Specifically, the speed setting range of the large gear oil tanker is between 0.19-1.84. However, when processing coarse denier yarn, in order to achieve the ideal effect, the required oil tanker speed range should be above 2.0. Obviously, the speed of the large gear oil tanker cannot meet the process standards of coarse denier yarn, so it must be replaced with a small gear of the oil tanker. The speed setting range of the oil tanker small gear is generally between 0.56-5.52. However, when making low-oil yarn, the oil tanker speed is about 0.3, and the minimum value of the small gear speed is 0.56, which again cannot meet the specific requirements of the process. For this reason, in order to adapt to different process requirements, the problem can only be solved by replacing the tanker gears and chains. However, this method will waste time for downtime replacement and greatly increase the workload of maintenance workers. In view of this, it is urgent to design a device that can switch the size of the tanker gears at any time. Summary of the invention

[0004] In order to solve one or some technical problems existing in the prior art, the purpose of this application is to provide a driving device that is convenient for switching the speed of the oil tanker of the TMT texturing machine, which can effectively solve the problem of cumbersome operation of setting the speed of the oil tanker when producing special varieties such as coarse and fine denier yarns, so that the improved oil tanker speed can be easily switched, with low labor intensity and high switching efficiency.

[0005] In order to solve the above existing technical problems, this application adopts the following technical solutions:

[0006] A driving device for conveniently switching the speed of a TMT texturizing machine oil tanker, characterized in that:

[0007] A driving motor and a driving gear arranged on the rotating shaft of the driving motor.

[0008] An oil tanker, a rotating shaft for mounting the oil tanker, one end of the rotating shaft being provided with a coupling,

[0009] A connecting shaft is installed on the head of the TMT texturing machine, and a frequency conversion gear set is detachably arranged on the connecting shaft. The rotating shaft is connected in series with the connecting shaft through the coupling. A chain is arranged between the driving gear and the frequency conversion gear set. The rotation speed of the tanker is controlled by switching the frequency conversion gear set and the chain.

[0010] Preferably, the frequency conversion gear set includes a large gear and at least one small gear fixed on one side or both sides of the large gear.

[0011] Preferably, the small gear and the large gear are fixed by electric welding or rivets, and the frequency conversion gear set and the connecting shaft are fixed by a pin or a nut.

[0012] Preferably, at least one tensioning wheel is provided between the connecting shaft and the frequency conversion gear set, and the redundant length of the chain generated during the switching process of the frequency conversion gear set is adjusted by the tensioning wheel.

[0013] Preferably, a gear scale bar is provided on the connecting shaft, and the relative position of the frequency conversion gear set on the connecting shaft can be quickly determined and fixed by the gear scale bar.

[0014] Preferably, an adjustment base is provided at the bottom of the driving motor, and the driving motor can be adjusted forward, backward, left and right relative to the frequency conversion gear set through the adjustment base.

[0015] Preferably, the adjustment base includes a bottom plate, a plurality of first adjustment holes and four second adjustment holes arranged on the bottom plate, the first adjustment holes and the second adjustment holes are cross-arranged, and the drive motor is fixed in the second adjustment holes by bolts.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The original single driven gear is replaced by the frequency conversion gear set, so that the driven gear does not need to be disassembled and replaced when the speed of the tanker and the rotating shaft is adjusted, which effectively shortens the replacement time and improves the replacement efficiency. It solves the problem that the tanker speed setting value can only be adjusted within the setting range when special varieties such as coarse and fine denier yarns are spun. The large and small gears of different diameters in the frequency conversion gear set can be switched at any time to meet the needs of adjusting the process, so that the tanker can better adapt to different process conditions and product requirements, which helps to maintain the stable operation of the tanker, reduce speed fluctuations, greatly reduce downtime, reduce the frequency of repairing and replacing tanker gears, reduce maintenance costs, and reduce the workload of maintenance workers. More reasonable speed settings help reduce energy consumption, and stable speed helps to improve product quality consistency and increase machine efficiency, which has a good promotion effect.

It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0025] As shown in 1, a driving device for switching the rotation speed of a TMT texturizing machine oil tanker comprises a driving motor 11, a driving gear 10 arranged on the rotating shaft of the driving motor 11, an oil tanker 2, a rotating shaft 1 for mounting the oil tanker 2, a coupling 3 being arranged at one end of the rotating shaft 1, a connecting rotating shaft 5 mounted on the head of the TMT texturizing machine, and a frequency conversion gear set 6 detachably arranged on the connecting rotating shaft 5, the rotating shaft 1 being connected in series with the connecting rotating shaft 5 through the coupling 3, a chain 8 being arranged between the driving gear 10 and the frequency conversion gear set 6, and the rotation speed of the oil tanker 2 is controlled by switching the frequency conversion gear set 6 and the chain 8.

[0026] When the rotation speed of the oil tanker 2 and the rotating shaft 1 needs to be adjusted, the rotation of the driving motor 11 is stopped, and then the driving gear 10 is meshed with different gears in the frequency conversion gear set 6 by replacing the chain 8, so as to realize the frequency conversion control of the oil tanker 2, wherein the original single driven gear is replaced by the frequency conversion gear set 6, so that when the rotation speed of the oil tanker 2 and the rotating shaft 1 is adjusted, it is no longer necessary to disassemble and replace the driven gear, which effectively shortens the replacement time and improves the replacement efficiency, solves the problem that the rotation speed setting value of the oil tanker 2 can only be adjusted within the setting range when the special varieties such as coarse and fine denier yarns are spun, and the large and small gears 61 of different diameters in the frequency conversion gear set 6 can be switched at any time to operate, so as to meet the needs of adjusting the process, so that the oil tanker 2 can better adapt to different process conditions and product requirements, help to maintain the stable operation of the oil tanker 2, reduce speed fluctuations, greatly reduce downtime, reduce the frequency of repairing and replacing the gears of the oil tanker 2, reduce maintenance costs, and reduce the workload of maintenance workers. More reasonable speed settings help to reduce energy consumption, and stable speeds help to improve product quality consistency, increase machine efficiency, and have a good promotion effect.

[0027] A further improvement is that the frequency conversion gear set 6 includes a large gear 62 and at least one small gear 61 fixed on one side or both sides of the large gear 62; the small gear 61 and the large gear 62 are fixed by electric welding or rivets, and the frequency conversion gear set 6 and the connecting shaft 5 are fixed by a pin or a nut.

[0028] Among them, the frequency conversion gear set 6 includes at least a large gear 62 with 60 teeth and a small gear 61 with 20 teeth. The small gear 61 and the large gear 62 are fixed by electric welding or rivets, for example, they are fixed together by 4 flat machine hexagonal nuts, so that when the process is adjusted, the large and small gears 61 can be switched at any time, which makes it easier to control and adjust the operating state of the speed of the tanker 2. In actual production, the existing 60-tooth diameter 190mm large gear 62 has a shaft guard with a diameter of 63mm on one side, which is machined on a lathe to an inner hole of 36mm and a thickness of 10mm. Then the inner hole of the 20-tooth diameter 65mm small gear 61 is machined on a lathe to an inner hole diameter of 36mm and a thickness of 10mm. Then the machined small gear 61 is installed on the shaft guard of the large gear 62 (tight fit). The connection between the large and small gears 61 is divided into four equal parts, and a 5.2mm drill is used to drill holes at the center points of the four equal parts; then a 12mm drill is used to slightly expand the hole for the next step of fastening the screws for installation, and then a 6mm tap is used for tapping, and a 6mm flat machine hexagon screw is used to reinforce the seam, which is convenient for disassembly. When the process requires the use of small gear 61, the 60-tooth large gear 62 can be flexibly switched to the 20-tooth small gear 61; on the contrary, when the commonly used 20-tooth small gear 61 is no longer applicable and needs to be replaced, it can also be quickly switched to the 60-tooth large gear 62. During the switching process, there is no need to maintain and replace the gears, saving cost and time. On the other hand, the operation is simple and easy, which effectively meets the diversified needs of process adjustment of tanker 2 and ensures that when special varieties are modified, the speed setting parameters of tanker 2 can be accurately within the set range, with good use effect. Due to its simple structure and durability, it greatly reduces the downtime cost and is more conducive to popularization and use.

[0029] Further improvement is as follows: Figure 2 and Figure 3 As shown, at least one tensioning wheel 7 is further provided between the connecting shaft 5 and the frequency conversion gear set 6 , and the redundant length of the chain 8 generated during the switching process of the frequency conversion gear set 6 is adjusted by the tensioning wheel 7 .

[0030] The gear diameter of the tensioning wheel 7 is 66mm, the thickness is 10mm, and the inner hole diameter is 20mm. Its function is to effectively adjust the tension of the chain 8 and ensure the smooth operation of the entire device. In the process of switching the large and small gears 61 on the frequency conversion gear set 6, in order to solve the problem that the chain 8 needs to be replaced accordingly during the switching process through the frequency conversion gear set 6, at least one tensioning wheel 7 is installed on the device connecting the rotating shaft 5 and the frequency conversion gear set 6. When the chain 8 is connected to the large gear 62, the tensioning wheel 7 does not contact the chain 8 or one of them contacts it, so as to avoid excessive relaxation of the chain 8. When the chain 8 switches to mesh with the small gear 61, the chain 8 in the excess slack area is tensioned by one or more tensioning wheels 7, so that the tanker 2 no longer needs to replace the chain 8 during the speed change process. In the specific switching process, the specific operations are as follows:

[0031] First, make sure that the equipment is in a shutdown state to ensure safe operation. Then, use an appropriate tool to loosen the nut of the tension wheel 7 appropriately. After the nut is loosened, relax the chain 8, and then switch the chain 8 to another required gear. Then adjust the chain 8 through the tension wheel 7, and tighten the nut after adjustment. During the entire switching process, always pay attention to the tension of the new gear chain 8 to ensure that it is within a reasonable range. After the switching operation is completed, carefully check the meshing state of the gears to confirm that the gears are operating normally. Therefore, there is no need to maintain the gears, and the cost of purchasing new gears and the labor cost required to replace the gears are saved. In the past, during the gear replacement process, not only did you need to purchase new adapter gears, but you also needed technicians to spend a lot of time on disassembly, installation, and debugging. Now, through simple switching operations, these additional cost expenditures can be avoided, greatly saving the company's production investment. It can not only shorten the equipment downtime caused by gear replacement, but also increase the effective operation time of the equipment, so that production tasks can be completed faster and production efficiency can be improved.

[0032] In practical applications, this innovative design has shown significant advantages. First, the speed of the tanker 2 can be controlled more accurately, so as to easily cope with the diverse requirements of different types of textiles. This enables the tanker 2 to adapt to various complex process conditions and diverse product requirements, effectively guarantees the stable operation of the tanker 2, and greatly reduces the fluctuation of the speed.

[0033] Secondly, since the large and small gears 61 of the oil tanker 2 can be switched at any time, the control and adjustment of the rotation speed of the oil tanker 2 becomes more convenient and efficient, thereby significantly reducing downtime. This improvement not only reduces the frequency of repairing and replacing the gears of the oil tanker 2, effectively reduces maintenance costs, but also greatly reduces the workload of maintenance workers.

[0034] Furthermore, more reasonable speed settings effectively reduce energy consumption. Stable speed plays a key role in improving product quality consistency and significantly increases the operating efficiency of the machine. It has extremely broad promotion prospects and great practical value.

[0035] As a further improvement, a gear scale bar 4 is provided on the connecting shaft 5 , and the relative position of the frequency conversion gear set 6 on the connecting shaft 5 can be quickly determined and fixed by the gear scale bar 4 .

[0036] When the position of the driving wheel is fixed, there will be an axial front-to-rear distance difference when the frequency conversion gear set 6 is switched. In order to ensure that the switched gear is on the same horizontal plane as the driving gear 10, it is necessary to adjust the position of the frequency conversion gear set 6 accordingly. Therefore, a gear scale bar 4 is formed on the connecting shaft 5, that is, different gears correspond to different scales. Therefore, when adjusting, it is only necessary to loosen the locking nut, and then move the axial position of the frequency conversion gear set 6, slide it to the corresponding scale and then tighten it to achieve rapid adjustment and positioning, and the stability of the chain 8 is better during transmission.

[0037] On the basis of the above trial method, it is further improved that an adjustment base 9 is provided at the bottom of the driving motor 11, and the driving motor 11 can be adjusted forward, backward, left and right relative to the frequency conversion gear set 6 through the adjustment base 9; the adjustment base 9 includes a bottom plate 92, a plurality of first adjustment holes 93 and four second adjustment holes 91 arranged on the bottom plate 92, the first adjustment holes 93 and the second adjustment holes 91 are cross-arranged, and the driving motor 11 is fixed in the second adjustment hole 91 by bolts.

[0038] When the frequency conversion gear set 6 uses two gears, due to the large size difference between the large and small sizes, when the large gear 62 and the driving gear 10 are engaged, the chain 8 is not tensioned by the tensioning wheel 7, but when it is engaged with the small gear 61, the added tensioning wheel 7 can just form tension. At this time, in order to facilitate the relaxation and tensioning of the chain 8, when the frequency conversion gear set 6 shaft position is in place, the drive motor 11 is adjusted forward, backward, left and right by adjusting the base 9, thereby achieving rapid switching of the chain 8 and control of the operating stability after switching. Among them, the adjustment base 9 is composed of a bottom plate 92 with a cross-arranged adjustment hole and a second adjustment hole 91. The bottom plate 92 is fixed to the frame or the ground through the first adjustment hole 93, and the drive motor 11 is fixed in the second adjustment hole 91 by bolts. After loosening the bolts, the drive motor 11 can be moved left and right along the long second adjustment hole 91, and the entire adjustment base 9 can also be moved forward and backward through the long first adjustment hole 93, thereby realizing the tightness adjustment of the chain 8 and switching without moving the frequency conversion gear set 6, and the operation flexibility is higher.

[0039] Its structure has been carefully optimized to show rationality and simplicity. In terms of performance, it shows high reliability and can function stably and continuously. The actual application effect is very good, fully meeting the stringent requirements of various types of textiles, so that the tanker 2 can adapt to a variety of process conditions and product requirements. This has effectively promoted the stable operation of the tanker 2, significantly reduced the speed fluctuation, and thus achieved precise adjustment of the process. In this process, the large and small gears 61 can be easily switched at any time without the need for security personnel to laboriously disassemble and replace them, which greatly reduces downtime. Moreover, the entire design is simple and clear, easy to operate, which not only lowers the technical threshold, but also provides great convenience for later maintenance and care.

[0040] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
