Description

Technical Field

[0001] This utility model relates to the field of drawing frame technology, and in particular to a drawing frame for textile processing that is easy to change bobbins. Background Technology

[0002] The function of a drawing frame is to improve the internal structure of the sliver, thereby increasing the uniformity of its long segments, reducing weight unevenness, straightening and paralleling the fibers in the sliver, reducing hooks, ensuring the fineness meets specifications, and uniformly mixing different types or qualities of raw materials to achieve the specified mixing ratio. Drawing frames are broadly classified into two categories based on their drafting mechanism: roller drafting frames and carding frames.

[0003] During operation, drawing frames require canister replacement. However, existing drawing frames typically require manual stopping of the machine, removal of the canister, replacement with a new canister, and restarting of the machine. This constant manual adjustment results in low efficiency and prevents automation. Therefore, a drawing frame for textile processing that can solve these problems and facilitate canister replacement is needed. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the background art by proposing a drawing frame for textile processing that facilitates bobbin changing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A drawing frame for textile processing that facilitates bobbin changing, comprising: Hollow machining table; The drawing frame body is fixedly installed on the top of the hollow processing table by a right-angle fixing bracket.

A drive wheel is coaxially fixedly mounted on the top of the disc. A notch is provided on the side of the drive wheel, and a round pin is provided outside the notch. The round pin is fixedly mounted on the top of the disc. A driven grooved wheel is slidably fitted on the top of the disc. Four radial grooves are provided on the edge of the driven grooved wheel, and the radial grooves are engaged or disengaged from the round pin. A drive motor for driving the drive wheel to rotate is fixedly mounted on the inner top of the hollow machining table. A self-starting component is used to drive the drawing frame body when the rotary table stops.

[0006] Preferably, the self-starting component includes a lifting plate slidably connected inside the hollow processing table. Two guide rods slide through the top of the lifting plate and are vertically fixed inside the hollow processing table. Springs are slidably sleeved on the surfaces of the two guide rods, and the two ends of the springs are respectively fixedly installed at the bottom of the lifting plate and the inner bottom of the hollow processing table.

[0009] Preferably, a rotating shaft is rotatably mounted on the inner bottom of the hollow machining table, and the upper end of the rotating shaft extends through the top of the hollow machining table and is coaxially fixed with the rotary table and the driven groove wheel.

[0010] Compared with existing technologies, the advantages of the drawing frame for textile processing provided by this utility model, which facilitates bobbin changing, are as follows: This invention controls the rotation of the active dial wheel by driving a motor. It utilizes the intermittent locking and sliding connection between the round pin and the radial groove on the driven groove wheel, as well as the contact between the protruding part of the active dial wheel and the locking arc on the driven groove wheel, to achieve intermittent rotation of the rotary table.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figures 1 to 3 A drawing frame for textile processing that facilitates bobbin changing, comprising: Hollow processing table 1; drawing frame body 2, fixedly installed on top of hollow processing table 1 by right-angle fixing bracket 3. A rotating table 4 is provided below the drawing frame body 2, and the rotating table 4 is rotatably installed on the top of hollow processing table 1. Multiple material cylinders 5 are inserted into the top of the rotating table 4. Four placement slots 16 are opened on the top of the rotating table 4, which is conducive to the accurate positioning of material cylinders 5. At the same time, it can also prevent the material cylinders 5 from shifting when the rotating table 4 rotates.

[0015] The intermittent rotary assembly includes a disc 6 rotatably mounted on the bottom of the hollow machining table 1. A drive wheel 7 is coaxially fixedly mounted on the top of the disc 6. A notch is provided on the side of the drive wheel 7, and a round pin 8 is provided outside the notch. The round pin 8 is fixedly mounted on the top of the disc 6. A driven grooved wheel 9 is slidably attached to the top of the disc 6. A rotating shaft 10 is rotatably mounted on the bottom of the hollow machining table 1. The upper end of the rotating shaft 10 movably passes through the top of the hollow machining table 1 and is coaxially fixed with the rotary table 4 and the driven grooved wheel 9.

[0016] The driven grooved wheel 9 has four radial grooves on its edge, and these radial grooves can engage or disengage with the round pin 8. A locking arc is provided between each pair of adjacent radial grooves on the driven grooved wheel 9. A drive motor 17 for driving the rotation of the drive wheel 7 is fixedly installed on the inner top of the hollow machining table 1. When the drive motor 17 is started, the drive wheel 7 and the disc 6 rotate synchronously, causing the round pin 8 to move in a circular motion. When the round pin 8 begins to slide into the radial groove on the driven grooved wheel 9, the protruding part of the drive wheel 7 disengages from the locking arc on the driven grooved wheel 9. Then, the round pin 8 pushes the driven grooved wheel 9 to rotate 90 degrees. Then, when the round pin 8 disengages from the radial groove on the driven grooved wheel 9, the protruding part of the drive wheel 7 contacts the locking arc of the driven grooved wheel 9 to lock the driven grooved wheel 9. By repeating this process, the rotary table 4 can be driven to rotate intermittently. This movement can be referenced from the Maltese intermittent mechanism in the prior art.

[0017] A self-starting assembly is used to drive the drawing frame body 2 when the rotary table 4 stops. The self-starting assembly includes a lifting plate 11 slidably connected inside the hollow processing table 1. Two guide rods slidably pass through the top of the lifting plate 11, and the two guide rods 13 are vertically fixed inside the hollow processing table 1. Springs 14 are slidably sleeved on the surfaces of the two guide rods 13, and the two ends of the springs 14 are respectively fixedly installed at the bottom of the lifting plate 11 and the inner bottom of the hollow processing table 1. A push-button switch 12 is provided above the lifting plate 11, and the push-button switch 12 is fixedly installed at the inner top of the hollow processing table 1 and electrically connected to the drawing frame body 2. The bottom of the lifting plate 11 and the top of the round pin 8 are both... A magnetic block 15 is fixedly installed, and the two magnetic blocks 15 repel each other when they are facing each other. When the round pin 8 disengages from the radial groove on the driven groove wheel 9, the driven groove wheel 9 is locked. Then, when the round pin 8 continues to rotate and the two magnetic blocks 15 are facing each other, they can repel the lifting plate 11 from moving upward and touching the push-button switch 12, which can control the drawing frame body 2 to run automatically and feed material into the corresponding barrel 5. Conversely, when the round pin 8 slides in connection with the radial groove on the driven groove wheel 9, the two magnetic blocks 15 no longer move downward relative to the lifting plate 11, the push-button switch 12 is reset, and the drawing frame body 2 stops working. By repeating this process, the automatic switching between different barrels 5 can be achieved, thus achieving the effects of automatic barrel changing and automatic feeding.

[0018] Furthermore, the drive motor 17 is surrounded by a magnetic shielding sleeve 18, and the magnetic shielding sleeve 18 is fixedly installed on the inner top of the hollow processing table 1, which can effectively shield the magnetic field generated by the drive motor 17 during operation from affecting the two magnetic blocks 15.

[0019] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
