Description

Technical Field

[0001] This utility model relates to the field of drawing machine technology, and in particular to a drawing machine that is easy to maintain. Background Technology

[0002] A drawing machine is a mechanical device used for fiber processing. It is mainly used to improve the physical properties of fibers by stretching and shaping. It is widely used in textile and non-woven fabric production and other fields. It stretches nascent fibers by the speed difference between rollers, making the molecular structure more compact along the axial direction, thereby improving fiber strength, reducing elongation, and finally obtaining linear density and physical properties that meet processing requirements.

[0003] After prolonged use, the drafting rollers of a drafting machine will suffer varying degrees of wear, requiring replacement and maintenance of severely worn drafting rollers. Common drafting machines have relatively simple structures, typically using bolts to fix the drafting rollers. During maintenance and replacement, disassembly and installation cannot be performed quickly, leading to reduced maintenance efficiency and insufficient practicality. Therefore, we propose a drafting machine that is easier to maintain. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. After prolonged use, the drafting rollers of a drafting machine will suffer varying degrees of wear, requiring replacement and maintenance of severely worn drafting rollers. Common drafting machine structures are relatively simple, typically using bolts to fix the drafting rollers. During maintenance and replacement, disassembly and installation cannot be performed quickly, leading to reduced processing efficiency and insufficient practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drawer that is easy to maintain includes a housing, wherein a plurality of drawer rollers are equidistantly mounted around the front of the housing near the bottom.

[0007] The interior of the housing is near the front side, and several motors are installed corresponding to the stretching rollers. The output end of the motor extends to the front side of the housing and is fixedly connected to a fixing column. A fixing component is installed at the end of the fixing column away from the motor.

[0008] The drawing roller is sleeved around the fixed column. Several fixed blocks are welded at equal intervals around the inside of the drawing roller near the front side. Several insert blocks are welded at equal intervals around the outside of the drawing roller near the back side.

[0009] As a preferred embodiment of this utility model, the back of the housing is rotatably connected to an inspection door via a hinge.

[0010] The technical advantage of adopting the above-mentioned further solution is that the internal structure of the casing can be quickly inspected through the inspection door, improving ease of use.

[0011] As a preferred embodiment of this utility model, a control panel is installed on the front of the housing near the top and right corner, and the control panel is electrically connected to the motor.

[0012] The technical advantage of adopting the above-mentioned further solution is that the motor can be controlled through the control panel, improving ease of use.

[0013] As a preferred embodiment of this utility model, a limiting ring is welded around the periphery of the fixed column near one end of the housing, and the insert block is inserted into the limiting ring.

[0014] The technical effect of adopting the above-mentioned further solution is that the limiting ring can limit the stretching roller sleeved on the outside of the fixed column, preventing it from sliding backward, and then fix it with the fixing component to improve the stability of use. By inserting the plug and the limiting ring, the stretching roller can rotate synchronously with the fixed column, preventing the fixed block from losing contact with the connecting part.

[0015] As a preferred embodiment of this utility model, the fixing component includes a fixing seat, which is rotatably connected to a fixing column. Several connecting parts are welded to the outer periphery of the fixing seat near the back side and corresponding to the fixing block. Insert rods are symmetrically slidably connected to the front side of the fixing seat near the top and bottom. The insert rods are inserted into the fixing column. A spring is sleeved on the outer periphery of the insert rod and inside the fixing seat.

[0016] The technical effect of adopting the above-mentioned further solution is that by rotating the fixed seat, the connecting piece can be driven to embed into the fixed block, and then the stretching roller can be fixed in conjunction with the limiting ring. The spring can push the insertion rod, thereby inserting the insertion rod into the fixed column, limiting the fixed seat, preventing the fixed seat from rotating during use, and improving the stability of use.

[0017] As a preferred embodiment of this utility model, a knob is welded to the front of the fixing base and located between the two insertion rods.

[0018] The technical advantage of adopting the above-mentioned further solution is that the knob makes it easier for users to rotate the fixed base, thus improving ease of use.

[0019] As a preferred embodiment of this utility model, the connector has a 7-shaped structure and is snapped into place with the fixing block.

[0020] The technical effect of adopting the above-mentioned further solution is that the snap-fit ​​between the 7-shaped connector and the fixed block can prevent the stretching roller from slipping off the outside of the fixed column, thereby improving the stability of use.

[0021] As a preferred embodiment of this utility model, a ring handle is welded to one end of the two insertion rods extending to the front of the fixing base.

[0022] The technical effect of adopting the above-mentioned further solution is that the plug rod can be pulled outwards simultaneously through the ring handle, thereby disengaging the plug rod from the fixed post and improving ease of use.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] In this invention, through the design of the housing and the drafting roller, and the coordinated use of the motor, fixed column, fixed seat, connector, plug rod, spring and fixing block, the drafting roller can be quickly installed and disassembled. Compared with the traditional bolt-fixed installation method, this greatly improves the convenience of operation and maintenance efficiency, and effectively enhances its practicality.

[0034] Example 1

[0035] like Figure 1-4 As shown, this utility model provides a technical solution: a drawer that is easy to maintain, including a housing 1. Several drawer rollers 2 are equidistantly mounted around the front of the housing 1 near the bottom. Several motors 101 are mounted inside the housing 1 near the front and corresponding to the drawer rollers 2. The output end of the motors 101 extends to the front of the housing 1 and is fixedly connected to a fixing post 102. A fixing component 103 is mounted on the end of the fixing post 102 away from the motors 101. The drawer rollers 2 are sleeved around the fixing post 102. Several fixing blocks 201 are equidistantly welded around the inside of the drawer rollers 2 near the front. Several insert blocks are equidistantly welded around the outer side of the drawer rollers near the back.

[0036] Example 2

[0037] like Figure 1-4As shown, a maintenance door 104 is rotatably connected to the back of the housing 1 via a hinge. The maintenance door 104 allows for quick inspection of the interior of the housing 1, improving ease of use. A control panel 105 is installed on the front of the housing 1 near the top and right corner. The control panel 105 is electrically connected to the motor 101, allowing control of the motor 101 and improving ease of use. A limit ring 1021 is welded around the periphery of the fixed column 102 near one end of the housing 1. The insert block 202 is inserted into the limit ring 1021, allowing the limit ring 1021 to control the stretching rollers fitted around the fixed column 102. 2. Limiting the movement prevents it from sliding backward, and then fixing it with the fixing component 103 to improve stability. By inserting the plug 202 into the limiting ring 1021, the stretching roller 2 can rotate synchronously with the fixing column 102, preventing the fixing block 201 from disengaging from the connecting piece 1032. The fixing component 103 includes a fixing seat 1031, which is rotatably connected to the fixing column 102. Several connecting pieces 1032 are welded to the outer periphery of the fixing seat 1031 near the back, corresponding to the fixing block 201. Insert rods 1033 are symmetrically slidably connected to the front of the fixing seat 1031 near the top and bottom. The insertion rod 1033 is inserted into the fixing post 102. A spring 1034 is sleeved around the insertion rod 1033 and inside the fixing seat 1031. By rotating the fixing seat 1031, the connecting piece 1032 can be driven to embed into the fixing block 201, thereby fixing the stretching roller 2 in conjunction with the limiting ring 1021. The spring 1034 can push the insertion rod 1033, thereby inserting the insertion rod 1033 into the fixing post 102, limiting the fixing seat 1031, preventing the fixing seat 1031 from rotating during use, and improving the stability of use. A welding rod is welded to the front of the fixing seat 1031 between the two insertion rods 1033. The knob 1035 facilitates the user's rotation of the fixed base 1031, improving ease of use. The connector 1032 is a 7-shaped mechanism and engages with the fixed block 201. The engagement between the 7-shaped connector 1032 and the fixed block 201 prevents the stretching roller 2 from slipping off the periphery of the fixed column 102, improving stability. The two insert rods 1033 extend to one end of the front of the fixed base 1031 and are welded with a ring handle 1036. The ring handle 1036 allows the insert rods 1033 to be pulled outwards simultaneously, thereby disengaging the insert rods 1033 from the fixed column 102 and improving ease of use.

[0038] The working process of this utility model is as follows: When maintaining and replacing the stretching roller of a stretching machine that is easy to maintain, first pull the ring handle forward, which simultaneously drives the two insert rods to slide forward and disengage from the fixed column. Then, turn the knob clockwise, which drives the connecting piece to rotate through the fixed seat, thereby disengaging it from the fixed block. The stretching roller can then be pulled out from the outside of the fixed column for maintenance and replacement. After that, the replaced stretching roller is re-sleeved around the fixed column and pushed backward, so that its back and the insert block are inserted into the limiting ring. Finally, turn the knob counterclockwise, which drives the connecting piece to re-embed into the fixed seat through the fixed seat, thus completing the entire replacement process. During the process, the spring pushes the insert rod backward, thereby inserting the insert rod into the fixed column and limiting the fixed seat to prevent rotation during use. Compared with the traditional bolt-fixed installation method, this greatly improves the convenience of operation and maintenance efficiency, and effectively improves practicality.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
