[0001] The invention relates to the technical field of textile industry, in particular to a drawing frame which is easy to adjust. Background Art

[0002] A drawing frame is a textile machine used to improve the internal structure of the sliver, increase the uniformity of its long segments, reduce the weight unevenness, straighten and parallel the fibers in the sliver, reduce hooks, and make the fineness meet the requirements. It can also make raw materials of different types or qualities blend evenly to achieve the specified blending ratio. Drawing frames are divided into two categories according to the form of drafting mechanism: roller drafting drawing frames and gilling machines.

[0003] The existing easy-to-adjust drawing frame, during use, uses multiple groups of roller structures such as guide wheels, transmission wheels and indirect wheels to transport the cotton slivers into the drawing frame in a certain direction and speed. However, when the cotton slivers are transported between the rollers, if they are in a tight state, it is easy for the surface of the cotton slivers to become fuzzy or even broken.

[0009] As a further solution of the present invention: the regulating control component comprises: A filter choke cylinder, which is fixedly mounted on the support plate and is also connected to the space adjustment chamber through a connecting pipe; A square guide frame, wherein the square guide frame is fixedly connected to the support plate; A telescopic cylinder, the telescopic cylinder is fixedly connected to the square guide frame and is connected to the filter choke cylinder through a connecting pipe, and a movable slide is slidably installed in the telescopic cylinder; And a rotation driving unit, wherein the rotation driving unit is respectively connected to the square guide frame and the movable slide plate, and the rotation driving unit is also respectively connected to the mounting seat and the control shaft.

[0013] Compared with the prior art, the present invention has the following beneficial effects: During the operation of the drawing machine, multiple cotton strips will be transported to the regulating box via the conveying rack, and enter the drawing box after passing through the conveying and adjusting mechanism in the regulating box. When the cotton strips enter the regulating box, first, the cotton strips will contact the conveying detection component and be transported under the guidance of the conveying detection component. In addition, by setting the guide splint and the deformable airbag, the surface of the deformable airbag is smooth, and the maximum height of the deformable airbag is slightly smaller than the height of the two guide splints, and is slidably connected with the inner wall of the guide splint. Therefore, an arc-shaped groove is formed between the guide splint and the deformable airbag. The cotton strips will be placed in the arc-shaped groove during the conveying process and will be connected with the inner wall of the guide splint. The deformable airbag is slidably connected, so that it can form a certain guiding effect on the tampon, so that the tampon is always in contact with the deformable airbag during the entire conveying process.

At this time, the detector can be used to detect the compressed state of the deformable airbag in real time, and then detect the tight state of the tampon during the entire conveying process. When the deformable airbag is compressed, the tension of the tampon will also change the conveying state of the conveying detection component, thereby driving the adjustment control component to work, so that A part of the high-pressure gas in the space regulating chamber is released. At this time, due to the decrease in the air pressure in the space regulating chamber, the deformable airbag will shrink upward in the guide splint, so that the taut cotton strips between the two mounting seats will gradually relax, avoiding the taut cotton strips from breaking due to tension during transportation, or causing the taut cotton strips to become fluffy due to excessive friction between the transportation detection component and the deformable airbag. After the deformable airbag shrinks upward for a certain distance, if the transportation state of the cotton strips returns to normal, the transportation detection component returns to the previous transportation state, and the adjustment control component stops working. At this time, the detector detects the air pressure in the space regulating chamber and transmits it to the control housing. The equipment is for staff to check. If the transport status of the sliver is still abnormal, the transport detection component and the adjustment control component will continue to work, so that the deformable airbag can gradually shrink upward until the transport status of the sliver returns to normal. If the transport status of the sliver is always abnormal, when the detection value of detector 1 is less than a set value, the equipment will shut down to facilitate inspection and maintenance by staff. The operation is simple, which can prevent the sliver from being fuzzed or broken due to excessive tension during transportation, and can automatically adjust according to the transport status, thereby improving the efficiency of subsequent production work and providing convenience for staff.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0025] See also Figure 1-Figure 8 An embodiment of the present invention provides a conveniently adjustable drawing frame, comprising a base plate 1, on which a control housing 2 and a conveying frame 8 are fixedly mounted, on which a drawing box 5 is fixedly mounted, and further comprising: An adjustment box 6, wherein the adjustment box 6 is connected to the drawing box 5 and the conveying frame 8 respectively, and a support plate 9 is fixedly installed in the adjustment box 6, and a space adjustment cavity 10 is fixedly installed on the support plate 9; A guide clamp plate 31, wherein the guide clamp plate 31 is fixedly connected to the support plate 9, and a deformation airbag 32 is provided between the two guide clamp plates 31, and the deformation airbag 32 is connected to the space adjustment cavity 10; and a conveying and adjusting mechanism, the conveying and adjusting mechanism is located in the adjusting box 6 and is respectively connected to the supporting plate 9 and the space adjusting chamber 10, and a cotton strip is also provided on the conveying and adjusting mechanism, and the cotton strip is slidably connected to the deformable airbag 32; The conveying and adjusting mechanism includes a mounting seat 17, a conveying detection component and an adjusting and controlling component; The mounting seat 17 is fixedly connected to the support plate 9 , the conveying detection component is connected to the mounting seat 17 , and a cotton strip is provided on the conveying detection component. The adjustment control component is respectively connected to the support plate 9 and the mounting seat 17 , and is connected to the space adjustment chamber 10 .

[0026] The height of the deformable airbag 32 is smaller than the height of the two guide clamps 31, and is slidably connected to the inner wall of the guide clamp 31, and an arc-shaped channel is formed between the guide clamp 31 and the deformable airbag 32; And a detector 11 is fixedly installed on the space adjustment chamber 10.

[0027] During the operation of the drawing machine, a plurality of cotton strips will be conveyed to the regulating box 6 via the conveying frame 8, and enter the drawing box 5 after passing through the conveying and regulating mechanism in the regulating box 6. When the cotton strips enter the regulating box 6, first, the cotton strips will contact the conveying detection component and be conveyed under the guidance of the conveying detection component. In addition, by setting the guide clamping plate 31 and the deformable airbag 32, wherein the surface of the deformable airbag 32 is smooth, and the maximum height of the deformable airbag 32 is slightly smaller than the height of the two guide clamping plates 31, and is slidably connected with the inner wall of the guide clamping plate 31, therefore, an arc-shaped channel is formed between the guide clamping plate 31 and the deformable airbag 32, and the cotton strips will be placed in the arc-shaped channel during the conveying process. The tampon is in the groove and is slidably connected with the deformable airbag 32, so that a certain guiding effect can be formed on the tampon, so that the tampon is always in contact with the deformable airbag 32 during the entire conveying process. During the tampon conveying process, when the tampon is in a tight state on the conveying detection component and the deformable airbag 32, it will produce an extrusion effect on the deformable airbag 32, and increase the gas pressure in the space adjustment chamber 10. At this time, the detector 11 can be used to detect the compressed state of the deformable airbag 32 in real time, and then detect the tight state of the tampon during the entire conveying process. When the deformable airbag 32 is compressed, the tension of the tampon will also change the conveying state of the conveying detection component, thereby driving the adjustment control component to be put into operation. The air bag 32 is in the air pressure regulating chamber 10, and the air bag 32 is in the air pressure regulating chamber 10. ... The tampon is detected and transported to the control housing 2 for the staff to check. If the transport state of the tampon is still in an abnormal state, the transport detection component and the adjustment control component continue to work, so that the deformable airbag 32 can gradually shrink upward until the transport state of the tampon returns to normal. If the transport state of the tampon is always abnormal, when the detection value of the detector 11 is less than a set value, the equipment will shut down to facilitate the staff to check and repair. The operation is simple, which can avoid the tampon from being too tight during the transport process, causing the surface to become fuzzy or being pulled apart, and can be automatically adjusted according to the transport state, thereby improving the efficiency of subsequent production work and providing convenience for the staff.

[0028] In one embodiment of the present invention, see Figure 1-Figure 8 , the conveying detection component comprises: A conveying slot 28, wherein the conveying slot 28 is provided on the mounting seat 17, and a control shaft 30 is rotatably mounted in the conveying slot 28; The limiting turntable 20 is two in number, and both limiting turntables 20 are sleeved on the control shaft 30 and are rotatably connected to the conveying slot 28 and the control shaft 30 respectively; And a detection driving unit, wherein the detection driving unit is located between the two limit rotating disks 20 and is detachably connected to the control rotating shaft 30 .

[0029] The detection drive unit comprises: A movable transmission wheel 27, the movable transmission wheel 27 is located between the two limit rotating disks 20 and is slidably connected to the inner wall of the limit rotating disk 20, and a circular hole 36 is also opened in the middle of the movable transmission wheel 27; A supporting spring 33, wherein the number of the supporting springs 33 is multiple, and the multiple supporting springs 33 are evenly distributed in the circular hole 36 and connected to the limiting rotating disk 20; And a plurality of toggle teeth 34 , wherein the plurality of toggle teeth 34 are evenly arranged in the circular hole 36 , and the toggle teeth 34 are detachably connected to the control shaft 30 .

[0030] After the sliver enters the regulating box 6, it passes through the conveying notches 28 on the two mounting seats 17 and contacts the movable transmission wheel 27. At this time, the sliver is conveyed in an M shape under the guidance of the two movable transmission wheels 27 and the deformable airbags 32. During the conveying process of the sliver, since the degree of extrusion between the sliver and the movable transmission wheel 27 is small, the support spring 33 is in a slightly compressed state (wherein the deformation of the support spring 33 can also relieve the tension of the sliver), and the sliver drives the movable transmission wheel 27 through the multiple support springs 33. The limit dial 20 is pulled to rotate on the control shaft 30. At this time, the toggle tooth piece 34 does not contact the control shaft 30, and the sliver is conveyed in a normal state. When the sliver is in a tight state during the conveying process, the sliver will exert a greater squeezing effect on the movable transmission wheel 27, and the support spring 33 will be compressed to a greater extent. At this time, one or more of the toggle tooth pieces 34 are in contact with the control shaft 30, and drive the control shaft 30 to rotate a certain angle following the limit dial 20, thereby driving the adjustment control component to work to relieve the tight state of the sliver.

[0031] In one embodiment of the present invention, see Figure 1-Figure 8 , the regulating control component comprises: A filter choke 12, wherein the filter choke 12 is fixedly mounted on the support plate 9, and the filter choke 12 is also connected to the space adjustment chamber 10 through a connecting pipe 13; A square guide frame 15, wherein the square guide frame 15 is fixedly connected to the support plate 9; A telescopic cylinder 14, wherein the telescopic cylinder 14 is fixedly connected to the square guide frame 15 and is connected to the filter choke cylinder 12 through a connecting pipe 13, and a movable slide plate 22 is slidably installed in the telescopic cylinder 14; And a rotation driving unit, the rotation driving unit is connected to the square guide frame 15 and the moving slide 22 respectively, and the rotation driving unit is also connected to the mounting seat 17 and the control shaft 30 respectively.

[0032] The rotary drive unit comprises: A push-pull rod 23, one end of which is fixedly connected to the movable slide plate 22, and the other end of which is slidably mounted in a guide detection cavity 24 provided on the square guide frame 15, and a sliding tooth plate 16 is also fixedly mounted on the push-pull rod 23; A second detector 25, the second detector 25 is located in the guide detection cavity 24 and is slidably connected to the push-pull rod 23; And a rotating slot 29, which is opened on the mounting seat 17 and is connected to the guide detection cavity 24 through the connecting slot 26, and a driving gear 21 is also provided in the rotating slot 29, and the driving gear 21 is fixedly connected to the control shaft 30 and meshingly connected to the sliding gear plate 16.

[0033] It also includes: a receiving groove 18, the receiving groove 18 is opened on the mounting seat 17, and a damping member 19 is arranged in the receiving groove 18, and the damping member 19 is connected to the control shaft 30; And a detector three 35 , wherein the detector three 35 is located on the control shaft 30 and is detachably connected to the shifting gear piece 34 , and the detector three 35 is also electrically connected to the damping member 19 .

[0034] At the moment when the toggle tooth piece 34 contacts and squeezes the control shaft 30, the toggle tooth piece 34 will generate pressure on the detector three 35, so that the detector three 35 controls the damping member 19 to start, wherein the detector three 35 can be in the form of a pressure sensor, and the damping member 19 can be in a cylindrical structure, and an electromagnet is arranged in the cylinder, the electromagnet is connected to the detector three 35, and contacts the end of the control shaft 30. At the moment when the toggle tooth piece 34 contacts the detector three 35, the electromagnet is powered off and loses its magnetism, and the control shaft 30 is in a freely rotatable state, so that the toggle tooth piece 34 can drive the control shaft 30 to rotate. When the toggle tooth piece 34 is not in contact with the detector three 35, the electromagnet is in an adsorption state for the end of the control shaft 30, so that the control shaft 30 is in a braking state. At the same time, the control shaft 30 is also connected to the mounting seat 17 in a damping connection manner to prevent the control shaft 30 from rotating. No more details are given here. When the control shaft 30 rotates, the control shaft 30 drives the driving gear 21 to rotate, and under the action of the meshing transmission between the driving gear 21 and the sliding tooth plate 16, the sliding tooth plate 16 moves to the outside of the square guide frame 15, so that the moving slide plate 22 can be pulled to move synchronously to the outside of the square guide frame 15 through the push-pull rod 23. At this time, the space on the left side of the moving slide plate 22 increases (such as Figure 4 As shown in the figure, since the sliver is in a tight state, it will squeeze the deformable airbag 32, and the gas pressure in the space regulating chamber 10 will increase. When the movable slide plate 22 moves, the gas in the space regulating chamber 10 will quickly enter the telescopic cylinder 14 through the filter choke cylinder 12, so that the air pressure in the space regulating chamber 10 is reduced. Among them, the filter choke cylinder 12 can adopt a cylindrical structure, and a sponge and other items are arranged inside the cylinder. On the one hand, it can filter impurities in the gas, and on the other hand, it can produce resistance to the flow of gas, so that the gas flows smoothly. When the air pressure in the space regulating chamber 10 decreases, the deformable airbag 32 will shrink upward, thereby relieving the tight state of the sliver during the transportation process. In addition, through the set detector 25, the moving state and moving position of the push-pull rod 23 can be detected, so that the staff can observe whether the equipment is operating normally. When the sliver returns to a relaxed state again, under the elastic action of the support spring 33, the movable transmission wheel 27 returns to its original position again, so as to achieve the purpose of automatic adjustment, thereby ensuring the normal transportation of the sliver.

[0035] In one embodiment of the present invention, see Figure 1-Figure 8 , further comprising: a ventilation upper cover 7, wherein the ventilation upper cover 7 is located on the top of the regulating box 6; And a tampon can 3 and an anti-slide plate 4, both of which are located on the base plate 1.

[0036] It should be noted that in the present invention, unless otherwise clearly specified and limited, the terms "slide", "rotate", "fix", "have" and the like should be understood in a broad sense, for example, it can be a welding connection, a bolt connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
