Description

Technical Field

[0001] The utility model relates to the technical field of cotton textile equipment, in particular to an independent drum pushing mechanism of a drawing frame. Background Art

[0002] In the existing spinning process, the drawing frame is an intermediate link in the spinning process and is indispensable. It is a key process to improve the quality of the yarn. Its function is to effectively control the weight deviation of the sliver, improve the uniformity of the sliver, the straightness and parallelism of the fiber, and make the fibers of different qualities more evenly mixed in the sliver, thus creating conditions for obtaining good yarn. Figure 1 、 Figure 2 The push-bottle structure shown in the figure is connected to the cover plate by screws, the cylinder is fixed on the slide groove by the cylinder seat, the bearing is installed between the cover plate and the slide groove, and the push-bottle frame is connected to the cover plate. When the cylinder is working, it will drive the cover plate to move, thereby driving the push-bottle frames on both sides to work, and further push the sliver cans in the full barrel state on both sides out of the working area and replace them with new empty sliver cans.

[0003] The existing pushing-barrel structure pushes the full sliver cans on both sides out of the working area and replaces them with new empty sliver cans. During this process, the sliver cans on both sides are in the same state of being pushed out. This structure is not suitable for independently driven double-eye drawing frames. Moreover, when the sliver cans are half-barreled and the sliver quality is tested, one side is pushed out for testing and the other side is also forced to be ejected, which greatly affects the production efficiency.

[0004] Therefore, we propose an independent barrel pushing mechanism for a drawing frame. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art. At present, the pushing drum structure pushes the sliver drums in the full drum state on both sides out of the working area and replaces them with new empty sliver drums. In this process, the sliver drums on both sides are in the same out state. This structure is not suitable for an independently driven double-eye drawing frame. Moreover, when the sliver drum is in the half-drum state and the sliver quality is tested, one side is pushed out for testing and the other side is also forced to be out of the drum, which greatly affects the production efficiency.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An independent drum pushing mechanism for a drawing frame comprises a fixed frame, wherein two fixed frames are symmetrically arranged, the front and rear inner walls of the fixed frames are fixedly connected to symmetrically distributed guide rails, the front of the fixed frame is fixedly connected to a cylinder seat, the back of the cylinder seat is fixedly mounted with a cylinder, one end of the cylinder piston rod is fixedly connected to a connecting piece, one side surface of the connecting piece is fixedly connected to a cover plate, and one side surface of the cover plate is fixedly connected to a drum pushing frame;

[0008] The other side surface of the cover plate is fixedly connected to a symmetrically distributed central rotating shaft, and rollers are mounted on the outer surface of the central rotating shaft via bearings. The plurality of rollers are symmetrically distributed in groups of two, and the outer surface of each group of rollers is in rolling contact with the outer surface of the guide rail;

[0009] The other side surface of the cover plate is provided with a wiping cleaning device, and the wiping cleaning device includes a positioning block, and one side surface of two positioning blocks is fixedly connected to the other side surface of the cover plate.

[0010] Preferably, the two positioning blocks are symmetrically distributed with the axis of the cover plate as the center, and a movable rod is movably sleeved on the inner wall of the positioning block.

[0011] Preferably, one end of the movable rod is fixedly connected to a stop block, the outer surface of the movable rod is movably sleeved with a contraction spring, and one end of the contraction spring is fixedly connected to the lower surface of the positioning block.

[0014] Preferably, the lower surface of the sponge wiping block contacts the upper surface of the mounting block, and the inner wall of the sponge wiping block contacts the outer surface of the guide rail.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1.

[0029] Example 1

[0030] like Figure 3-6 As shown, the utility model provides a technical solution: an independent barrel pushing mechanism of a drawing frame, comprising a fixed frame 1, two fixed frames 1 are symmetrically distributed, the front and rear inner walls of the fixed frames 1 are fixedly connected with symmetrically distributed guide rails 2, the front of the fixed frame 1 is fixedly connected with a cylinder seat 3, the back of the cylinder seat 3 is fixedly installed with a cylinder 4, one end of the piston rod of the cylinder 4 is fixedly connected with a connecting piece 5, one side surface of the connecting piece 5 is fixedly connected with a cover plate 6, one side surface of the cover plate 6 is fixedly connected with a barrel pushing frame 7, the extension and retraction of the piston rod of the cylinder 4 drives the cover plate 6 to move through the connecting piece 5, thereby driving the barrel pushing frame 7 to move;

[0031] The other side surface of the cover plate 6 is fixedly connected to a symmetrically distributed central shaft 8. The outer surface of the central shaft 8 is mounted with rollers 9 via bearings. The rollers 9 are arranged in groups of two and are symmetrically distributed. The outer surface of each group of rollers 9 is in rolling contact with the outer surface of the guide rail 2. The rolling cooperation between the rollers 9 and the guide rail 2 guides the extension and retraction of the cylinder 4 and limits its rotation.

[0032] A wiping cleaning device is provided on the other side surface of the cover plate 6 , and the wiping cleaning device includes positioning blocks 10 , and one side surface of two positioning blocks 10 are fixedly connected to the other side surface of the cover plate 6 .

[0033] Example 2

[0034] like Figure 3-6 As shown, the utility model provides a technical solution: two positioning blocks 10 are symmetrically distributed with the axis of the cover plate 6 as the center, and the inner wall of the positioning block 10 is movably sleeved with a movable rod 101, and the movement of the cover plate 6 drives the positioning block 10 to move.

[0035] One end of the movable rod 101 is fixedly connected to a stop block 102 , and a contraction spring 103 is movably sleeved on the outer surface of the movable rod 101 . One end of the contraction spring 103 is fixedly connected to the lower surface of the positioning block 10 , and the positioning block 10 guides the movement of the movable rod 101 .

[0036] The other end of the contraction spring 103 is fixedly connected to the upper surface of the stop block 102, and the other end of the movable rod 101 is fixedly connected to the mounting block 104. A limiting slot 105 is provided on one side surface of the mounting block 104. The contraction spring 103 exerts elastic pressure on the movable rod 101 through the stop block 102.

[0037] The inner wall of the limiting slot 105 is movably connected to the limiting plug 106, and the upper surface of the limiting plug 106 is fixedly connected to the sponge wiping block 107. The limiting slot 105 and the limiting plug 106 cooperate to facilitate the replacement of the sponge wiping block 107.

[0038] The lower surface of the sponge wiping block 107 contacts the upper surface of the mounting block 104 , and the inner wall of the sponge wiping block 107 contacts the outer surface of the guide rail 2 . The sponge wiping block 107 serves to wipe away dust and impurities adsorbed on the surface of the guide rail 2 .

[0039] Through the arrangement of the guide rail 2 and the roller 9, the cylinder 4 can stably drive the push cylinder frame 7 to move to prevent rotation, and cooperate with the wiping cleaning device to automatically clean the guide rail 2 to avoid the situation where the roller 9 is stuck due to the adsorption of dust and impurities. The structure is simple, and the cylinders 4 on both sides work independently without interfering with each other, which is convenient for maintenance. One side can work while the other side can be repaired, which greatly improves the production efficiency.

[0040] By reducing the cylinder diameter of the air cylinder 4, its acting force is reduced, thereby preventing the sliver can from being damaged by violent pushing, thereby increasing the service life of the sliver can.

[0041] The working process of this utility model:

[0042] Step 1: When the cylinder 4 is working, the piston rod of the cylinder 4 drives the cover plate 6 to move through the connecting piece 5. The movement of the cover plate 6 drives the sliver can to move and push out through the can pusher 7. When the cover plate 6 moves, it rolls on the guide rail 2 through the roller 9, thereby guiding the extension of the piston rod of the cylinder 4 and limiting its rotation, thereby ensuring the working stability.

[0043] In step 2, when the cover 6 moves, the movable rod 101 is driven to move by the positioning block 10, and the movement of the movable rod 101 drives the sponge wiping block 107 to move through the installation block 104. The sponge wiping block 107 is applied with the elastic force exerted by the contraction spring 103 to make it fit the guide rail 2 and automatically wipe and sweep away the dust and impurities adsorbed on the surface of the guide rail 2 through movement, thereby avoiding the phenomenon of the roller 9 getting stuck after contact. When the sponge wiping block 107 needs to be replaced, the movable rod 101 is pulled out of the guide rail 2 by the stop block 102, and then the limit plug 106 is pulled out from the limit slot 105 to remove the sponge wiping block 107, and the new sponge wiping block 107 is inserted into the limit slot 105 through the limit plug 106 for limit installation.

[0044] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
