Description

Technical Field

[0001] The utility model relates to the technical field of mechanical tooling, in particular to a bobbin holder for a textile machine. Background Art

[0002] The existing bobbin holder of a textile machine is an important component in textile machinery, mainly used for supporting and fixing yarn bobbins. However, there are some obvious defects in the design of the existing bobbin holder, which affect the maintenance and use efficiency of the equipment.

[0003] First of all, the disassembly and assembly process of the existing bobbin holder is relatively cumbersome. Generally, the bobbin holder fixes the bearing through a circlip. Although this design is simple, it is inconvenient to operate and time-consuming and laborious when the bearing needs to be disassembled or replaced. Especially in an industrial environment that requires frequent maintenance, this design increases the maintenance cost and downtime.

[0004] Secondly, the pin shaft in the bobbin holder is prone to wear. As a key positioning element, the wear of the pin shaft will directly affect the running accuracy and stability of the textile machine, especially the coaxiality of the central shaft for mounting the bobbin. In a high-speed running textile machine, the rapid wear of the pin shaft will cause the positioning accuracy of the bobbin holder to decrease, thereby affecting the operation yield of the textile machine. Content of the Utility Model

[0005] In view of this, the utility model provides a bobbin holder for a textile machine to solve the above technical problems.

[0006] A bobbin holder for a textile machine includes a first connecting arm, a second connecting arm spaced from the first connecting arm, and a connecting member connecting the first connecting arm and the second connecting arm.

[0022] The following further details the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein does not limit the protection scope of the present invention.

[0023] As Figures 1 to 5 shown, it is a structural schematic diagram of a bobbin holder for a textile machine provided by the present invention. The bobbin holder for a textile machine includes a first connecting arm 10, a second connecting arm 20 spaced apart from the first connecting arm 10, and a connecting member 30 connecting the first connecting arm 10 and the second connecting arm 20. It can be imagined that the bobbin holder for a textile machine further includes some other functional structures, such as assembly components, installation components, etc., which are well-known technologies to those skilled in the art and will not be elaborated herein.

[0024] Please refer to Figure 3 , the device is rotatably arranged on the clutch device 1 through the first connecting arm 10 and the second connecting arm 20. The clutch device 1 itself is an existing functional mechanism of textile machinery. When the winding bobbin 2 is not fully wound, it is in the engaged state. At this time, the winding bobbin 2 is always in contact with a driving wheel, so that the winding bobbin 2 rotates under the drive of the driving wheel to perform winding. When the winding bobbin 2 is fully wound, the clutch device 1 will be in the disengaged state under the abutment of the bobbin 2. At this time, the winding bobbin 2 is disengaged from the driving wheel. At this time, the winding bobbin 2 can be removed, and an unwound winding bobbin 2 can be installed. Then, the clutch device 1 is pressed to make it in the engaged state, and the winding bobbin 2 is again brought into contact with the driving wheel to perform the next round of winding.

[0025] The first connecting arm 10, the second connecting arm 20 and the connecting member 30 are all made by precision machining to ensure the accuracy of the structure, shape and size, so as to ensure the assembly accuracy.

[0026] The first connecting arm 10 includes a connecting arm body 11, a frame bearing hole 12 provided at one end of the connecting arm body 11, a bobbin tube bearing hole 13 provided at the other end of the connecting arm body 11, and a bobbin tube bearing baffle 14 covering the bobbin tube bearing hole 13.

[0027] The middle region of the connecting arm body 11 is connected and fixed to the connecting member 30, and the connection method can be fastener connection or welding. In this embodiment, the connection method between the connecting arm body 11 and the connecting member 30 is fastener connection, which is convenient for disassembly and replacement.

[0028] On the side of the frame bearing hole 12 facing away from the clutch device 1, there is a frame mounting opening 121, and on the side facing the clutch device 1, there is a frame abutting opening 122. The diameter of the frame mounting opening 121 is larger than the diameter of the frame abutting opening 122. At the same time, the frame mounting opening 121 and the frame abutting opening 122 are coaxially arranged, and the diameter of the frame mounting opening 121 is equivalent to the outer diameter of the installed bearing. Thus, an operator can install the bearing into the frame bearing hole 12 from the frame mounting opening 121, and one surface of the bearing abuts against the frame abutting opening 122.

[0029] On one side of the bobbin tube bearing hole 13, there is a bobbin tube mounting opening 131, and on the other side, there is a bobbin tube abutting opening 132. The diameter of the bobbin tube mounting opening 131 is also larger than the diameter of the bobbin tube abutting opening 132. The operator installs the bearing into the bobbin tube bearing hole 13 from the bobbin tube mounting opening 131. The bobbin tube mounting opening 131 is arranged on the side facing the second connecting arm 20 or on the side facing away from the second connecting arm 20.

[0030] Please refer to Figure 3 , the frame bearing hole 12 is used to connect the clutch device 1, and the bobbin tube bearing hole 13 is used to connect the winding bobbin 2. The bobbin tube bearing baffle 14 covers the bobbin tube mounting opening 131.

[0031] The bobbin tube bearing baffle 14 covers the bobbin tube mounting opening 131 to fix the bearing in the bobbin tube bearing hole 13 and at the same time plays a role in dust prevention. The bobbin tube bearing baffle 14 and the bobbin tube mounting opening 131 are connected by fasteners such as bolts, which is convenient for disassembly and replacement of the bearing. It can be imagined that after installing the bearing in the frame bearing hole 12 for assembling with the clutch device 1 at the other end, the bearing can be fixed in the frame bearing hole 12 by a circlip. This is because although the bearing in the frame bearing hole 12 assembled with the clutch device 1 also rotates, the frequency is relatively low and the damage probability is small. Therefore, a circlip can be used for fixation, which helps to reduce costs.

[0032] The second connecting arm 20 includes a front arm 21, a rear arm 22 inserted into one end of the front arm 21, and an elastic member 23 connecting the front arm 21 and the rear arm 22. The length after the front arm 21, the rear arm 22 and the elastic member 23 are interconnected is the same as the length of the first connecting arm 10.

[0033] The front arm 21 includes a front arm main body 211, a front arm bearing hole 212 provided at one end of the front arm main body 211, a front arm connecting portion 213 provided at the other end of the front arm main body 211, and a front arm bearing baffle 214 covering the front arm bearing hole 212.

[0034] The front arm bearing hole 212 has the same structure as the tube bearing hole 13. Specifically, a front arm mounting port 215 is provided on one side of the front arm bearing hole 212, and a front arm abutting port 216 is provided on the other side. An operator can install a bearing from the front arm mounting port 215 and abut it against the front arm abutting port 216. The front arm mounting port 215 is provided on the side facing the first connecting arm 10 or on the side facing away from the first connecting arm 10.

[0035] Please refer to Figure 2 , the profile of the front arm connecting portion 213 is "concave" along the length direction for plugging and connecting with the rear arm 22.

[0036] The front arm bearing baffle 214 covers the front arm mounting port 215, fixes the bearing to the front arm bearing hole 212, and fixes the front arm bearing baffle 214 to the front arm mounting port 215 with a fastener such as a bolt. A handle 217 is extended on the side of the front arm bearing baffle 214 away from the front arm connecting portion 213, facilitating the operator to toggle the front arm main body 21 through the handle 217 so that the front arm main body 21 opens in a direction away from the first connecting arm, thereby enabling the installation of an empty winding tube 2 or the removal of a fully wound winding tube 2 when the front arm main body 21 opens.

[0037] The rear arm 22 includes a rear arm main body 221, a rear arm bearing hole 222 provided at one end of the rear arm main body 221, and a rear arm connecting portion 223 provided at the other end of the rear arm main body 221. The rear arm bearing hole 222 has the same structure as the frame bearing hole 12. After installing a bearing, the bearing can be fixed to the rear arm bearing hole 222 by a circlip.

[0038] Please continue to refer to Figure 2, the contour of the rear arm connecting portion 223 is in a "convex" shape along the length direction and is inserted into the "concave" shape of the front arm connecting portion 213 in an inserting manner. It can be imagined that the front arm connecting portion 213 and the rear arm connecting portion 223 are in a concave-convex fit. This inserting structure can also be designed as the fit between a conical pit and a cone, which can also achieve the purpose of concave-convex fit. Through the inserting manner between the front arm connecting portion 213 and the rear arm connecting portion 223, it is used to improve the strength of the front arm connecting portion 213 and the rear arm connecting portion 223 in the vertical direction, and try to avoid bending the elastic member 23 under the action of the driving wheel when the winding cylinder 2 is installed.

[0039] A clearance fit is provided between the rear arm connecting portion 223 and the front arm connecting portion 213, and the elastic member 23 connects the rear arm connecting portion 223 and the front arm connecting portion 213 into a whole. The elastic member 23 is arranged on the end faces of the rear arm connecting portion 223 and the front arm connecting portion 213 away from the first connecting arm 10 side, and the clearance fit enables the operator to dial the front arm main body 211 in a direction away from the first connecting arm 10 by dialing the handle 217, so that the front arm main body 211 is opened to disassemble or install the winding cylinder 2.

[0040] Through the precise design and processing of the lengths of the front and rear arms 21 and 22 and the elastic member 23, as well as the positions and dimensions of the fastening connection holes between the front and rear arms 21 and 22 and the elastic member 23, it is ensured that there is a high coaxiality between the rear arm bearing hole 222 and the frame bearing hole 12, and between the front arm bearing hole 212 and the bobbin tube bearing hole 13, and at the same time, it is ensured that the connection line of the central axes of the rear arm bearing hole 222 and the frame bearing hole 12 and the connection line of the central axes of the front arm bearing hole 212 and the bobbin tube bearing hole 13 have a high parallelism. Please refer to Figure 1 , after bearings are installed in both the front arm bearing hole 212 and the bobbin tube bearing hole 13, a bobbin tube insert 40 is fixedly arranged in the through hole of the bearing. The structure of the bobbin tube insert 40 is shown in Figure 5 , which includes a connecting column 41 and a plugging column 42 arranged at one end of the connecting column 41. The connecting column 41 and the bearing can be fixed by a circlip, so that the bobbin tube insert 40 can drive the inner ring of the bearing to rotate, reducing the wear of the connecting column 41. When installing the winding cylinder 2, both ends of the winding cylinder 2 can be directly sleeved on the plugging column 42, and the winding cylinder 2 is clamped by the elastic member 23.

[0041] When in use, the bobbin rack is rotatably mounted on the clutch device 1 through the rear arm bearing hole 222 and the bearing in the frame bearing hole 12 on the same side. The handle 217 is moved to open the forearm body 211, and the winding reel 2 is sleeved on the connector in the bobbin bearing hole 13 and the bearing in the forearm bearing hole 212.

[0042] The connector 30 includes a connector body 31 and connecting ends 32 vertically disposed at two ends of the connector body 31 .

[0043] A reinforcing block 33 is disposed in the middle area of the connector body 31 to increase the contact area with the clutch device 1 so that the connector body 31 can be better stressed. The two connecting ends 32 are respectively connected and fixed to the first connecting arm body 11, the forearm body 211, and the rear arm body 221.

[0044] Compared with the prior art, the bobbin rack for a textile machine provided by the utility model divides the second connecting arm 20 into a front arm 21, a rear arm 22, and an elastic member 23, and the elastic member 23 is used to replace the traditional pin to connect the front arm 21 and the rear arm 22, thereby avoiding the pin wear affecting the accuracy. At the same time, the bobbin bearing baffle 14 and the front arm bearing baffle 214 replace the retaining spring and are respectively fixed to the bobbin bearing hole 13 and the front arm bearing hole 213 by fasteners such as bolts. When maintenance is required, the bobbin bearing baffle 14 and the front arm bearing baffle 214 can be directly disassembled, which is convenient for maintenance and replacement. At the same time, by respectively setting the frame bearing hole 12 and the rear arm bearing hole 222 at both ends of the first connecting arm 10 and the second connecting arm 20 and installing bearings, the rotation stability and wear resistance can be increased, and the service life can be extended.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
