Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology, specifically, it relates to a beater structure of a cotton grabber and the cotton grabber itself. Background Technology

[0002] The primary process in modern textile spinning is opening and cleaning the cotton. The first step in the opening and cleaning process is cotton grabbing, which is done by a cotton grabbing machine. The function of the cotton grabbing machine is to loosen, remove impurities, and mix the raw material bales. Among them, the disc cotton grabbing machine is widely used. However, the existing disc beaters have a relatively small gap with the wall panel, which can easily cause cotton to get tangled between the beaters and the wall panel during the cotton grabbing process, leading to the beaters getting hot. If the temperature of the beaters gets too high, it can easily cause a fire.

[0003] In view of the above, this utility model is hereby proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a beater structure and a cotton grabber. By setting a temperature detection device on the bearing seat to detect the temperature of the beater shaft head, the temperature of the beater shaft head of the cotton grabber can be detected in real time. When the actual temperature of the beater shaft head is relatively high, the beater shaft is stopped from rotating to prevent cotton from continuing to entangle between the beater and the wall panel, thereby avoiding the problem of the beater getting hot and eliminating the fire caused by the excessive temperature of the beater structure.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a beater structure for a cotton grabber, including a wall panel, a beater shaft, and a beater frame sleeved on the beater shaft. A bearing seat is installed on the outer side of the wall panel. The shaft head of the beater shaft passes through the inner side of the wall panel and is rotatably connected to the bearing seat. A temperature detection device for detecting the temperature of the beater shaft head is provided on the bearing seat.

[0007] Furthermore, the bearing housing is provided with a shaft hole coaxial with the throttle shaft, and the shaft head of the throttle shaft can be rotatably inserted into the shaft hole;

[0008] The temperature detection device is located on the bearing housing on the outer periphery of the shaft hole.

[0009] Furthermore, the bearing housing on the outer periphery of the shaft hole is provided with a mounting portion located near the shaft hole;

[0010] The temperature detection device is located on the mounting section.

[0011] Furthermore, the temperature detection device is a temperature sensor;

[0012] The mounting part is a mounting hole on the bearing seat located on the outer periphery of the shaft hole. One end of the mounting hole is an open end that communicates with the outside, and the other end is located close to the shaft hole.

[0013] The temperature sensor probe is inserted into the mounting hole through the open end of the mounting hole.

[0014] Furthermore, the mounting hole extends radially along the shaft hole, and the other end of the mounting hole near the shaft hole is a closed end;

[0015] The temperature sensor probe is inserted into the mounting hole and contacts the closed end of the mounting hole.

[0016] Furthermore, the bearing housing includes a bearing housing body with a shaft hole and an annular mounting seat formed by the radial extension of the outer peripheral wall of the bearing housing body along the shaft hole;

[0017] The annular mounting base fits and is fixedly connected to the outer side of the wall panel;

[0018] The mounting hole is located on the bearing housing body on the outer periphery of the shaft hole, outside the annular mounting seat.

[0019] Furthermore, the mounting hole is located on the bearing housing body above the shaft hole.

[0020] Furthermore, the temperature sensor is a threaded temperature sensor, and one end of the temperature sensor probe is provided with mounting threads;

[0021] The inner wall of the mounting hole is provided with a hole wall thread that is screwed into the mounting thread.

[0022] This utility model also provides a cotton grabbing machine, including the beater structure of the cotton grabbing machine provided in the above technical solution.

[0023] Furthermore, it also includes the control cabinet, temperature controller, and secondary circuit of the control cabinet;

[0024] The temperature sensor is connected to the temperature controller located on the control cabinet;

[0025] The control point of the temperature controller is connected in series with the secondary circuit of the control cabinet.

[0026] When the actual temperature of the beater shaft head detected by the temperature sensor reaches the set temperature of the temperature controller, the secondary circuit of the control cabinet is automatically powered off, causing the beater shaft to stop rotating.

[0027] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.

[0028] 1. This application provides a temperature detection device on the bearing housing to detect the temperature of the beater shaft head. This device can detect the temperature of the beater shaft head of the cotton grabber in real time. When the actual temperature of the beater shaft head is relatively high, the device can stop the beater shaft from rotating to prevent cotton from continuing to entangle between the beater and the wall panel. This can prevent the beater from overheating and thus eliminate the fire caused by the excessive temperature of the beater structure.

[0029] 2. The bearing housing of this application not only has the function of supporting the beater shaft, but also provides an installation position for a temperature detection device for detecting the temperature of the beater shaft.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] like Figure 1 and 2 As shown, this utility model provides a beater structure for a cotton grabber, including a wall panel, a beater shaft 2, and a beater frame 3 sleeved on the beater shaft 2. A bearing seat 4 is installed on the outer side of the wall panel. The shaft head 21 of the beater shaft passes through the inner side of the wall panel and is rotatably connected to the bearing seat 4. A temperature detection device 5 for detecting the temperature of the shaft head of the beater shaft 2 is provided on the bearing seat 4.

[0040] In the embodiments of this utility model, through the above-mentioned settings, the temperature of the head of the beater shaft 2 of the cotton grabber can be detected in real time. When the actual temperature of the head of the beater shaft 2 is relatively high, the beater shaft 2 can be stopped from rotating to prevent the cotton from continuing to entangle between the beater and the wall panel, thereby avoiding the problem of the beater getting hot and eliminating the fire caused by the beater being too hot.

[0041] The beater structure of a cotton grabber typically includes two opposing wall panels, with a bearing seat 4 installed on the outer side of each wall panel. Figure 1 Only one wall panel is shown. The side of the wall panel located between two wall panels is the inner side of the wall panel, and the side of the wall panel not located between two wall panels is the outer side of the wall panel. The inner side and the outer side of the wall panel are set opposite to each other. The shaft head of one end of the hammer shaft 2 passes through the inner side of one wall panel and is rotatably connected to the corresponding bearing seat 4. The shaft head of the other end passes through the inner side of another wall panel and is rotatably connected to the corresponding bearing seat 4. Each bearing seat 4 is equipped with a temperature detection device 5 to detect the temperature of the shaft head of the hammer shaft 2 at the corresponding position.

[0042] The wall panel, as part of the structure, serves to support and fix other components. The beater shaft 2 is the rotating component of the beater structure, responsible for driving the beater frame 3. The beater shaft 2 can be hollow internally to reduce the weight of the beater structure. The beater frame 3 is specifically fitted onto the outer peripheral wall of the beater shaft 2 and is the part that actually grasps or processes cotton. The beater frame 3 is driven to rotate by an external drive mechanism (not shown in the figure). Further, the beater frame is cylindrical, and the beater frame 3 is equipped with comb needles arranged spirally along its circumference. The bearing seat 4 supports and mounts the beater shaft 2. The bearing seat 4 is equipped with rolling bearings, and the shaft head 21 of the beater shaft is inserted into the rolling bearings to achieve the rotation function of the beater shaft 2. A temperature detection device 5 is installed on the bearing seat 4 to detect the temperature of the shaft head 21 of the beater shaft. This function is of great significance for monitoring the working status of the beater shaft 2 and preventing abnormal conditions such as overheating or damage.

[0043] In this embodiment of the present invention, the bearing seat 4 is provided with a shaft hole 411 coaxial with the beater shaft 2, and the shaft head 21 of the beater shaft is rotatably inserted into the shaft hole 411.

[0044] The temperature detection device 5 is located on the bearing seat 4 on the outer periphery of the shaft hole 411.

[0045] In this embodiment of the present invention, the shaft hole 411 and the bearing seat 4 are coaxially arranged, so that the axis of the shaft hole 411 is completely coincident with the axis of the beater shaft 2, ensuring that the beater shaft 2 can be inserted and rotated smoothly and accurately.

[0046] The shaft head 21 of the beater shaft is rotatably inserted into the shaft hole 411, thereby connecting the beater shaft 2 to the bearing seat 4 and allowing the beater shaft 2 to rotate freely within the bearing seat 4.

[0047] The temperature detection device 5 is installed on the bearing seat 4 of the outer shaft of the shaft hole 411. In order to prevent friction between the temperature detection device 5 and the rotating hammer shaft 2 and to avoid damage to the temperature detection device 5, the temperature detection device 5 can not directly contact the hammer shaft. It can indirectly reflect the temperature condition of the shaft head 21 of the hammer shaft by monitoring the temperature change around the bearing seat 4 or the shaft hole 411, thereby reflecting the temperature condition of the hammer.

[0048] In this embodiment of the present invention, a mounting portion 412 is provided on the bearing seat 4 on the outer periphery of the shaft hole 411, which is close to the shaft hole 411; the temperature detection device 5 is provided on the mounting portion 412.

[0049] In this embodiment of the invention, the mounting part 412 is positioned close to the shaft hole 411, meaning that the mounting part 412 is located on the bearing seat 4 at a position relatively close to the shaft hole 411, which allows for more accurate detection of the temperature of the shaft head 21 of the beater shaft. The temperature detection device 5 can be a temperature sensor, thermometer, etc.

[0050] Furthermore, the temperature detection device 5 is a temperature sensor 51;

[0051] The mounting part 412 is a mounting hole 412a provided on the bearing seat 4 on the outer periphery of the shaft hole 411. One end of the mounting hole 412a is an open end that communicates with the outside, and the other end is provided close to the shaft hole 411.

[0052] The probe 511 of the temperature sensor is inserted into the mounting hole 412a through the open end of the mounting hole 412a.

[0053] Temperature sensor 51 is a sensor that can sense temperature and convert it into a usable output signal, typically an electrical signal such as voltage, current, or resistance; preferably, the temperature sensor 51 used in this application is a platinum resistance temperature sensor.

[0054] Specifically, the mounting hole 412a is located on the bearing seat 4 on the outer periphery of the shaft hole 411, which can be understood as the mounting hole 412a being located on the peripheral wall of the bearing seat 4; the open end of the mounting hole 412a allows the probe 511 of the temperature sensor to be inserted, while the other end of the mounting hole 412a near the shaft hole 411 is the position where the probe 511 of the temperature sensor is closest to the target detection area, which is the hand shaft 2; the mounting hole 412a can extend obliquely or vertically on the bearing seat 4 on the outer shaft of the shaft hole 411.

[0055] Furthermore, the mounting hole 412a extends radially along the shaft hole 411, and the other end of the mounting hole 412a near the shaft hole 411 is a closed end;

[0056] The probe 511 of the temperature sensor is inserted into the mounting hole 412a and contacts the closed end of the mounting hole 412a.

[0057] Mounting hole 412a extends from bearing seat 4 in a direction perpendicular to the axis of shaft hole 411, that is, radially along shaft hole 411, making mounting hole 412a extend vertically in a straight line. This design allows temperature sensor probe 511 to be inserted vertically and directly into mounting hole 412a, enabling temperature sensor 51 to be closer to the shaft head 21 of the actuator shaft for temperature measurement. The temperature sensor probe 511 contacts the closed end of mounting hole 412a, ensuring more accurate heat transfer between the temperature sensor probe 511 and the shaft head 21 of the actuator shaft while allowing indirect measurement of the temperature of the actuator shaft head 21.

[0058] To ensure that heat can be effectively transferred from the shaft head 21 of the beater shaft to the probe 511 of the temperature sensor, the closed end of the mounting hole 412a can be made of a material with good thermal conductivity, or a heat-conducting layer can be provided on the inner or outer end face of the closed end of the mounting hole 412a, and the heat-conducting layer can be made of a material with good thermal conductivity.

[0059] In addition, the structure of the mounting hole 412a can also be: one end of the mounting hole 412a is an open end that communicates with the outside, and the other end is set near the shaft hole 411 and is also an open end.

[0060] In an embodiment of this utility model, the bearing housing 4 includes a bearing housing body 41 with a shaft hole 411 and an annular mounting seat 42 formed by the radial extension of the outer peripheral wall of the bearing housing body 41 along the shaft hole 411.

[0061] The annular mounting base 42 is fitted and fixedly connected to the outer side of the wall panel;

[0062] Mounting hole 412a is provided on the bearing housing body 41 on the outer periphery of shaft hole 411 other than annular mounting seat 42.

[0063] In the embodiments of this utility model, the annular mounting base 42 can be fixedly connected to the wall panel by means of screw connection, welding, etc.; when screw connection is used, the annular mounting base 42 is provided with a fixing hole for fixed connection with the wall panel, and the fixing hole passes through the annular mounting base 42 along the axial direction of the shaft hole 411.

[0064] The mounting hole 412a is not located on the annular mounting base 42, but on the bearing housing body 41 outside the shaft hole 411 outside the annular mounting base 42. This means that the mounting hole 412a is a certain distance from the annular mounting base 42, preventing the annular mounting base 42 from affecting the insertion of the temperature sensor probe 511 into the mounting hole 412a. The temperature sensor 51 is set on the bearing housing 4, so that the bearing housing 4 not only has the function of supporting the handbrake shaft 2, but also can conveniently detect the temperature of the handbrake shaft 2.

[0065] Furthermore, the mounting hole 412a is provided on the bearing housing body 41 above the shaft hole 411, which facilitates the insertion of the temperature sensor probe 511 into the mounting hole 412a.

[0066] In the embodiments of this utility model, the temperature sensor 51 is a threaded temperature sensor 51, and one end of the temperature sensor 51 probe is provided with an installation thread 512.

[0067] The inner wall of the mounting hole 412a is provided with a hole wall thread that is screwed into the mounting thread 512.

[0068] The probe 511 of the temperature sensor has a mounting thread 512 at one end. This design allows the sensor to be fixed in the mounting hole 412a by screwing the mounting thread 512 into the hole wall thread. This screwing connection is simple and reliable, ensuring the stability and accuracy of the temperature sensor 51 in the mounting hole 412a. Since threaded temperature sensors are common in the market, their specific structure and working principle will not be described in detail here. More preferably, the temperature sensor 51 of this application is a threaded platinum resistance temperature sensor.

[0069] This utility model also provides a cotton grabbing machine, including a beater structure of the cotton grabbing machine, as well as a temperature controller and a secondary circuit of the control cabinet;

[0070] Temperature sensor 51 is connected to a temperature controller located on the control cabinet;

[0071] The control point of the temperature controller is connected in series with the secondary circuit of the control cabinet.

[0072] When the actual temperature of the head of the beater shaft 2 detected by the temperature sensor 51 reaches the set temperature of the temperature controller, the secondary circuit of the control cabinet is automatically powered off, causing the beater shaft 2 to stop rotating.

[0073] In this embodiment of the invention, the control cabinet is a housing for electrical control components and is responsible for the power distribution and control logic of the entire cotton grabber.

[0074] The secondary circuit of the control cabinet is a part inside the control cabinet and is used to control the power supply for starting and stopping the actuator mechanism.

[0075] Specifically, temperature sensors 51 are provided on the bearing seat 4 corresponding to the shaft head at one end of the beater shaft 2 and the bearing seat 4 corresponding to the shaft head at the other end, and the two temperature sensors 51 are respectively connected to the temperature controller.

[0076] Temperature sensor 51 can detect the temperature of the head of the beater shaft 2 in real time and transmit the temperature data to the temperature controller. The temperature controller is the core component of the temperature control safety protection system. It receives the temperature data from temperature sensor 51 and compares it with the set temperature. When the actual temperature reaches the set temperature, the temperature controller will trigger the control point and send a signal to the secondary circuit of the control cabinet.

[0077] The secondary circuit of the control cabinet is part of the power control system of the cotton grabber. When it receives a signal from the temperature controller, the secondary circuit of the control cabinet will automatically cut off the power, thereby cutting off the power supply to the beater structure. Specifically, it will cut off the power supply to the drive mechanism that drives the beater frame and beater shaft to rotate, so that the beater shaft 2 stops rotating, thereby eliminating the fire caused by the excessive temperature of the beater structure.

[0078] After the beater shaft 2 stops rotating, clean the tangled fibers from the shaft head 21. When the actual temperature is lower than the set temperature of the temperature controller, power on the secondary circuit of the control cabinet.

[0079] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
