Description

Technical Field

[0001] The utility model relates to the technical field of spinning production equipment, and more specifically, to an anti-slip transmission shaft device. Background Art

[0002] The metering pump is an important component on spinning production equipment. It is mainly used to accurately measure the output of the spinning raw material melt to ensure that the thickness of the yarn remains consistent. The metering pump is driven by the motor drive shaft structure when in use. Due to the compact structure of the spinning equipment, the installation position of the metering pump has the problem of narrow operating space. There are great difficulties in connecting the metering pump and the drive shaft. At present, a retractable drive shaft is used to complete the transmission connection. The drive shaft is installed vertically when in use, and the retractable section naturally droops and is inserted into the metering pump to form a transmission effect. However, in the actual production process, there is occasional melt leakage at the metering pump position. When the melt leaks, the melt will push the telescopic section of the drive shaft out of the metering pump connection position. At this time, although the drive shaft is rotating, the metering pump does not work effectively. After the melt stops leaking, the telescopic section of the drive shaft will be inserted again under the effect of its own weight to achieve connection. At this time, the metering pump can work effectively again. That is to say, in actual production, the metering pump will occasionally stop running (the so-called transmission slip phenomenon). The occurrence of this situation is very hidden and not easy to detect, but it will cause serious quality accidents. During the chaotic operation of the metering pump, the fineness of the produced silk thread will change, which will cause the silk thread to be scrapped. Therefore, how to ensure that the drive shaft does not have occasional transmission slippage is the focus of the current enterprise technical transformation research. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art and to provide an anti-skid transmission shaft device. The device forms an upward limit of the telescopic shaft by installing a sleeve assembly on the telescopic shaft, so that the leaked melt will not be able to lift up the telescopic shaft, and the telescopic shaft can always maintain a docking state with the metering pump, thereby ensuring the stable operation of the metering pump.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A non-slip transmission shaft device is used in metering pump equipment, comprising a main shaft body, a telescopic shaft body and a ferrule assembly. The telescopic shaft body is movably inserted in the main shaft body, a transmission joint is connected to the bottom of the telescopic shaft body, and the ferrule assembly is fixedly mounted on the outer wall of the telescopic shaft body. The ferrule assembly can move with the telescopic shaft body, and the bottom of the main shaft body blocks the movement path of the ferrule assembly.

[0006] Furthermore, the ferrule assembly includes two stop seats, which are semicircular seats. The two stop seats are symmetrically installed and connected by bolts. The two stop seats can form an effect of clamping on the telescopic shaft.

[0007] Furthermore, the arc inner wall of the stop seat is set as a friction surface.

[0008] Furthermore, two symmetrically arranged key slots are provided on the outer wall of the telescopic shaft, and a positioning protrusion is provided on the arc inner wall of the stop seat. The size of the positioning protrusion matches the key slot, and when the stop seat is installed, the positioning protrusion is just installed in the key slot.

[0009] Furthermore, a buffer pad is connected to and installed on the stop seat. The stop seat is installed with the buffer pad facing upward. After the stop seat is installed, the buffer pad contacts the bottom of the main shaft body. The buffer pad is made of a flexible deformable material.

[0010] Furthermore, an anti-slip transmission shaft device also includes a slurry leakage warning component, which includes a mounting frame and a pressure sensor. The mounting frame is fixedly connected to the outer wall of the main shaft body, and the pressure sensor is installed on the mounting frame. A linkage pressure plate is connected to the outer wall of one of the stop seats, and the pressure sensor is arranged on the movement trajectory of the linkage pressure plate.

[0011] Furthermore, when the buffer pad is in a relaxed state, a gap is left between the pressure sensor and the linkage pressure plate, and after the buffer pad is compressed and deformed, the linkage pressure plate can be pressed onto the pressure sensor.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model forms an upward limit of the telescopic shaft by installing a sleeve assembly on the telescopic shaft, so that the leaked melt will not be able to lift up the telescopic shaft, and the telescopic shaft can always maintain a docking state with the metering pump, ensuring the stable operation of the metering pump.

[0014] 2. The utility model is also equipped with a slurry leakage warning component, which forms a pressure signal through the slight position change of the telescopic shaft, so that workers can find and record the slurry leakage at the position of the metering pump in time, so as to facilitate subsequent equipment maintenance work.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] .like Figure 1-Figure 3 The anti-skid transmission shaft device shown is applied to metering pump equipment, including a main shaft body 1, a telescopic shaft body 2 and a ferrule assembly 3. The telescopic shaft body 2 is movably inserted in the main shaft body 1, and the main shaft body 1 plays a role in guiding the movement of the telescopic shaft body 2. The main shaft body 1 is connected to the telescopic shaft body 2 by transmission and can rotate synchronously to form an effect of transmitting power. A transmission joint 21 is connected to the bottom of the telescopic shaft body 2. When the utility model is installed, the main shaft body 1 is erected, and the telescopic shaft body 2 naturally droops under the action of gravity, so that the transmission joint 21 is inserted into the connection position of the metering pump to form a transmission connection. This installation method is very simple, and the transmission connection can be completed even if the installation space of the metering pump is limited. The ferrule assembly 3 is fixedly installed on the outer wall of the telescopic shaft body 2, and the ferrule assembly The telescopic shaft body 2 is installed after it is determined to be connected to the metering pump. The ferrule assembly 3 can move with the telescopic shaft body 2. The outer dimensions of the ferrule assembly 3 match the bottom dimensions of the main shaft body 1. Therefore, the bottom of the main shaft body 1 will block the movement path of the ferrule assembly 3. Specifically, the bottom of the main shaft body 1 blocks the upward movement path of the ferrule assembly 3. Since the ferrule assembly 3 cannot move upward, the telescopic shaft body 2 cannot move upward either. In this way, when the metering pump melt leaks, the telescopic shaft body 2 cannot be pushed upward, and the telescopic shaft body 2 cannot be disconnected from the metering pump, thereby achieving the effect of maintaining the working state of the metering pump. After applying the utility model, the telescopic shaft body 2 can always maintain the docking state with the metering pump to ensure the stable operation of the metering pump.

[0021] like Figure 1 and Figure 2As shown, the ferrule assembly 3 includes two stop seats 31, which are semicircular seats. The two stop seats 31 are symmetrically installed and connected by bolts. A gap is left between the two installed stop seats 31. After tightening the bolts, the two stop seats 31 can form an effect of clamping on the telescopic shaft body 2. The two stop seats 31 are clamped on the outer wall of the telescopic shaft body 2 and are fixed by friction. As long as the friction force is greater than the upward force generated by the melt leakage, the stop seat 31 can always form an upward blocking effect on the telescopic shaft body 2. The arc inner wall of the stop seat 31 is set as a friction surface 311. The arc inner wall of the stop seat 31 is directly in contact with the outer wall of the telescopic shaft body 2, and the friction surface 311 should be designed to be relatively rough to form a better friction clamping effect.

[0022] like Figure 1 and Figure 2 As shown, two symmetrically arranged key slots 22 are provided on the outer wall of the telescopic shaft body 2, and a positioning protrusion 312 is provided on the arc inner wall of the stop seat 31. The size of the positioning protrusion 312 matches the key slot 22. When the stop seat 31 is installed, the positioning protrusion 312 is just installed in the key slot 22. The key slot 22 itself can be used for the transmission connection (key connection) between the main shaft body 1 and the telescopic shaft body 2, so that the two can rotate at the same time to form power transmission. In the utility model, the existence of the key slot 22 can also be used to position and install the two stop seats 31. With the cooperation of the positioning protrusion 312 and the key slot 22, a positioning and installation effect of the stop seat 31 can be formed, so that the two stop seats 31 can be smoothly installed and docked.

[0023] like Figure 1 and Figure 3As shown, in the present invention, the stop seat 31 is connected and installed with a buffer pad 32, and the stop seat 31 is installed with the buffer pad 32 facing upward. After the stop seat 31 is installed, the buffer pad 32 contacts the bottom of the main shaft body 1, and the buffer pad 32 is made of a flexible deformable material. The buffer pad 32 is installed by an adhesive connection. Since the buffer pad 32 is installed on the top of the stop seat 31, when the telescopic shaft body 2 is pushed up, the buffer pad 32 first acts on the bottom of the main shaft body 1. Since the buffer pad 32 is made of a flexible deformable material (the enterprise uses rubber), it can form a flexible stop effect, and the buffer The pad 32 can not only meet the stop requirement, but also protect the bottom of the main shaft body 1, so that the bottom of the main shaft body 1 will not be damaged by the extrusion force. When the metering pump melt leaks and the telescopic shaft body 2 is pushed up, the rubber buffer pad 32 can have a certain deformation compression amount, and this compression amount is not large. The telescopic shaft body 2 can have a certain upward displacement, but the displacement is not large, and the connection will not be disconnected. However, the displacement of the telescopic shaft body 2 can be used to warn the occurrence of leakage. The anti-skid transmission shaft device also includes a leakage warning component 4, which includes a mounting frame 41 and a pressure sensor. The pressure sensor 42 is mounted on the mounting frame 41 and connected to the outer wall of the main shaft body 1. A linkage pressure plate 33 is connected to the outer wall of one of the stopper seats 31. Since the stopper seat 31 is positioned and installed, after the stopper seat 31 is installed, the pressure sensor 42 is just located on the motion trajectory of the linkage pressure plate 33. After the initial installation of the stopper seat 31 is completed, the buffer pad 32 is in a relaxed state. At this time, there is a gap between the pressure sensor 42 and the linkage pressure plate 33, and the pressure sensor 42 is not triggered. When the metering pump leaks melt, the telescopic shaft body 2 will have The upward trend, after the telescopic shaft body 2 is pushed up, the buffer pad 32 will be compressed and deformed, and the telescopic shaft body 2 forms a slight upward movement, and its connection with the metering pump is maintained, but the linkage pressure plate 33 of the stop seat 31 can be pressed on the pressure sensor 42. At this time, the pressure sensor 42 can form a signal to transmit externally, prompting the workers that the metering pump has a leakage problem, so that the workers can promptly discover and record the leakage at the metering pump position, so as to facilitate subsequent equipment maintenance work (this leakage occurs occasionally and is very hidden and difficult to find. The above structure of the utility model helps to promptly discover the above fault problem).

[0024] When the utility model is used, the main shaft body 1 is first erected, the telescopic shaft body 2 is naturally drooped and connected to the metering pump, and then the ferrule assembly 3 is installed. When the ferrule assembly 3 is installed, the buffer pads 32 of the two stop seats 31 should be in contact with the bottom of the main shaft body 1, but the buffer pads 32 should not be pressed tightly and need to be kept in a relaxed state. Then the pressure sensor 42 is debugged to ensure that the pressure sensor 42 at this time does not contact the linkage pressure plate 33.

[0025] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
