Description

Technical Field

[0001] The present invention relates to the technical field of linen production, and particularly relates to a controllable feeding assembly for processing raw materials in linen production and preparation. Background Art

[0002] Linen is woven from twisted linen fibers. Due to the high fiber strength, tear resistance, and puncture resistance, it is highly favored in the textile industry. In the production process of linen, the roving frame is one of the key equipment, responsible for processing linen silk into roving, laying the foundation for subsequent textile processes, and feeding the linen fiber strips in combination with feeding equipment.

[0003] For example, a controllable feeding device for linen production with the publication number CN222312309U can clamp and fix the fiber strip roll through the provided clamping assembly. However, due to the fixed shape of the clamping block, it is only applicable to clamp the inner wall of the fiber strip roll with a frustum-shaped structure. For a cylindrical or frustum-shaped structure with different inclination angles, it is impossible to achieve self-adaptive and stable fitting clamping, thus greatly limiting the application range of the device; and by manually adjusting the position of the resistance plate to control the rotational resistance between the rotating seat and the fixed roller, although the phenomenon of "thread explosion" can be avoided, it is difficult to adjust the tension of the fiber strip during feeding in real time to ensure that the feeding tension is always in an ideal state. Summary of the Invention

[0004] The purpose of the present invention is to provide a controllable feeding assembly for processing raw materials in linen production and preparation to solve the above-mentioned technical defects.

[0005] The purpose of the present invention can be achieved through the following technical solutions: A controllable feeding assembly for processing raw materials in linen production and preparation includes a fixed seat, as well as a control panel and an air outlet pipe fixedly installed on the fixed seat. A plurality of adaptive damping mechanisms are arranged on the air outlet pipe, and a detection type tension adjustment mechanism is arranged on the fixed seat;

[0006] The adaptive damping mechanism includes a rotating sleeve rotatably installed on the air outlet pipe, and a plurality of clamping plates are movably installed on the outer side wall of the rotating sleeve. A resistance ring one is installed on the inner wall of the rotating sleeve, and a resistance ring two is movably installed on the air outlet pipe and is matched with the resistance ring one. The detection type tension adjustment mechanism includes two groups of guide rollers and a plurality of evenly distributed pressing wheels located between the two groups of guide rollers.

[0007] Preferably, a piston ring fixedly connected to the resistance ring two slides on the air outlet pipe. An auxiliary cylinder fixedly connected to the air outlet pipe and slid by the piston ring is provided, and the auxiliary cylinder is rotatably connected to the rotating sleeve.

[0008] Preferably, an air outlet hole communicating with the inside of the corresponding rotating sleeve is formed in the air outlet pipe, and an electromagnetic control valve is installed in the air outlet hole. A cylinder sleeve is fixedly connected to the fixed seat, and a support plate is fixedly connected to the inside of the cylinder sleeve. One side of the support plate is provided with a main piston block sliding in the cylinder sleeve through an electric push rod, and an air inlet pipe is fixedly communicated between the cylinder sleeve and the air outlet pipe.

[0009] Preferably, a plurality of piston cavities are formed through the annular inner wall of the rotating sleeve, and a secondary piston block is slidably connected in the piston cavity. An installation plate cooperating with the corresponding clamping plate is fixedly connected to the secondary piston block.

[0010] Preferably, a U-shaped seat is fixedly connected to the middle of one side of the installation plate. A rotating block hinged to the U-shaped seat is fixedly connected to the clamping plate. Spring I is fixedly connected between the installation plate and the clamping plate on both sides of the rotating block.

[0011] Preferably, two groups of grooves are formed on the side of the clamping plate away from the rotating sleeve, and V-shaped spring pieces are hinged to the opposite sides of the grooves. The free ends of the spring pieces are in an arc structure and slide in the corresponding grooves.

[0012] Preferably, a cross plate is fixedly connected to the fixed seat, and a U-shaped frame is slidably connected to the cross plate. A bracket for rotating the corresponding pressing wheel is fixedly connected to the U-shaped frame. A pushing plate slidably connected to the U-shaped frame is fixedly connected to the bracket through Spring II.

[0013] Preferably, the same number of annular limiting grooves as the rotating sleeve are formed on the annular outer wall of the guide roller. A limiting plate is fixedly connected to the fixed seat, and anti-deviation holes cooperating with the corresponding annular limiting grooves are formed on the limiting plate.

[0014] The beneficial effects of the present invention are as follows:

[0015] (1) In the present invention, a plurality of fiber strip rolls are sequentially sleeved outside the corresponding rotating sleeves. The fiber strip rolls sleeved are preliminarily fixed by the spring pieces on the clamping plates to initially maintain the placement position of the fiber strip rolls before fixation. By injecting gas into the rotating sleeves, first, the secondary piston block is pushed to drive the clamping plate to move, which can not only realize the fixed clamping of the fiber strip rolls but also combine with the rotation of the clamping plate to adaptively fit and contact the conical or cylindrical inner walls of the fiber strip rolls, so as to improve the application range of the feeding assembly and realize the stable fixation treatment of fiber strip rolls with different inner wall shapes.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1: Please refer to Figures 1 - 6 As shown, for the problem that fiber strip rolls with different inner wall shapes cannot be stably clamped and fixed, the following solutions can be adopted;

[0032] In this embodiment, a controllable feeding component for processing raw materials in linen production includes a fixed seat 1, and a control panel 11 and an air outlet pipe 12 fixedly installed on the fixed seat 1. A plurality of adaptive damping mechanisms 2 are arranged on the air outlet pipe 12. Through the plurality of adaptive damping mechanisms 2, a plurality of fiber strip rolls can be installed simultaneously for feeding processing. A detection type tension adjusting mechanism 3 is arranged on the fixed seat 1 to detect and adjust the tension of the fed fiber strips;

[0033] The adaptive damping mechanism 2 includes a rotating sleeve 21 rotatably installed on the air outlet pipe 12. The rotating sleeve 21 is rotatably connected to the air outlet pipe 12 in a sealed manner. A plurality of clamping plates 22 are movably installed on the outer side wall of the rotating sleeve 21. The plurality of clamping plates 22 are equidistantly distributed. The fiber strip rolls for linen production are sleeved on the outer side of the corresponding rotating sleeve 21. The plurality of clamping plates 22 move away from each other to realize the clamping and fixing of the fiber strip rolls. A first resistance ring 23 is installed on the inner wall of the rotating sleeve 21, and a second resistance ring 13 is movably installed on the air outlet pipe 12 and is matched with the first resistance ring 23;

[0034] The first resistance ring 23 is located on one side inside the rotating sleeve 21 and contacts the first resistance ring 23 by moving the second resistance ring 13, so as to realize the rotational resistance of the rotating sleeve 21. And through the different contact forces between the second resistance ring 13 and the first resistance ring 23, the feeding tension is adjusted. The detection type tension adjusting mechanism 3 includes two groups of guide rollers 31 and a plurality of evenly distributed pressing wheels 32 located between the two groups of guide rollers 31. The fiber strip on the fiber strip roll is output after being guided by the two groups of guide rollers 31 and the corresponding pressing wheels 32. Combined with the damping rotation of the rotating sleeve 21, the fiber strip roll is subjected to a tensioned feeding process during the unwinding process.

[0035] A piston ring 14 fixedly connected to the second resistance ring 13 slides on the air outlet pipe 12. An auxiliary cylinder 15 slidable with the piston ring 14 is fixedly connected to the air outlet pipe 12. The piston ring 14 is in sealed sliding connection with the air outlet pipe 12 and the auxiliary cylinder 15. Through the setting of the auxiliary cylinder 15, the piston ring 14 is prevented from contacting the rotating sleeve 21, and the multi-directional movement between the piston ring 14 and the rotating sleeve 21 is eliminated, so as to solve the problem of poor sealing between the rotating sleeve 21 and the air outlet pipe 12. And the auxiliary cylinder 15 is rotationally connected to the rotating sleeve 21;

[0036] The rotating sleeve 21 is in sealed rotational connection with the auxiliary cylinder 15. A limiting rod 16 slidable with the auxiliary cylinder 15 is fixedly connected to the piston ring 14 for restricting the rotation of the piston ring 14. A return spring 17 is fixedly connected between the piston ring 14 and the auxiliary cylinder 15. The auxiliary piston ring 14 drives the second resistance ring 13 to separate from the first resistance ring 23. By injecting gas into the rotating sleeve 21 to accumulate and push the piston ring 14 to stretch and move the return spring 17, the piston ring 14 is caused to carry the second resistance ring 13 to contact the first resistance ring 23, thus completing the damping rotation of the rotating sleeve 21.

[0037] An air outlet hole 18 communicating with the inside of the corresponding rotating sleeve 21 is opened on the air outlet pipe 12. By injecting gas into the air outlet pipe 12, the gas then enters the inside of the corresponding rotating sleeve 21 through the corresponding air outlet hole 18. And an electromagnetic control valve is installed in the air outlet hole 18. A cylinder sleeve 19 is fixedly connected to the fixing seat 1, and a support plate is fixedly connected to the inside of the cylinder sleeve 19. A main piston block 111 slidable with the cylinder sleeve 19 is installed on one side of the support plate through an electric push rod 110. The main piston block 111 is in sealed sliding connection with the cylinder sleeve 19;

[0038] An air inlet pipe is fixedly connected between the cylinder sleeve 19 and the air outlet pipe 12. By controlling the piston rod of the electric push rod 110 to extend through the control panel 11, the main piston block 111 is caused to slide in the cylinder sleeve 19, and the gas in the cylinder sleeve 19 is injected into the air outlet pipe 12 through the air inlet pipe, and then injected into the inside of the corresponding rotating sleeve 21 through a plurality of air outlet holes 18.

[0039] A plurality of piston chambers 24 are penetratingly formed in the annular inner wall of the rotating sleeve 21, and a secondary piston block 25 is slidably connected in the piston chamber 24. The secondary piston block 25 is in sealed sliding connection with the piston chamber 24, and a mounting plate 26 that cooperates with the corresponding clamping plate 22 is fixedly connected to the secondary piston block 25;

[0040] After a plurality of fiber strip coils are sequentially sleeved on the outside of the corresponding rotating sleeve 21, the gas in the cylinder sleeve 19 is injected into the inside of the rotating sleeve 21. First, it pushes a plurality of secondary piston blocks 25 to synchronously carry the corresponding mounting plates 26 to move, causing the clamping plates 22 to contact the inner wall of the fiber strip coil to complete the fixing process of the fiber strip coil. Then, through the contact between the clamping plate 22 and the inner wall of the fiber strip coil, the continuous movement of the secondary piston block 25 is restricted, and the gas accumulated in the rotating sleeve 21 is used to push the piston ring 14 to stretch and reset the tension spring 17 to move, so that the second resistance ring 13 contacts the first resistance ring 23, and the damped rotation of the rotating sleeve 21 is completed.

[0041] A U-shaped seat is fixedly connected to the middle of one side of the mounting plate 26, and a rotating block hinged to the U-shaped seat is fixedly connected to the clamping plate 22 for realizing the rotational connection between the mounting plate 26 and the clamping plate 22. Spring one 27 is fixedly connected between the mounting plate 26 and the clamping plate 22 and on both sides of the rotating block. The arrangement of the two groups of spring one 27 is used to assist the horizontal state between the mounting plate 26 and the clamping plate 22, thereby avoiding the inclination of a certain clamping plate 22 and affecting the convenience of sleeving the fiber strip coil;

[0042] When the clamping plate 22 contacts the inner wall of the fiber strip coil, through the rotational connection between the mounting plate 26 and the clamping plate 22, each clamping plate 22 is adaptively fitted and abutted against the conical or cylindrical inner wall of the fiber strip coil, and the two side spring one 27 are respectively stretched or compressed to assist the clamping plate 22 to firmly clamp the fiber strip coil.

[0043] Two groups of grooves 28 are formed on the side of the clamping plate 22 away from the rotating sleeve 21, and V-shaped spring pieces 29 are hinged to the opposite sides of the grooves 28. When the fiber strip coil is sleeved on the outside of the corresponding rotating sleeve 21, the spring pieces 29 on the clamping plate 22 can preliminarily fix the positions of a plurality of fiber strip coils before they are jointly clamped, so as to maintain the placement position of the fiber strip coil before it is fixed and improve the installation convenience;

[0044] The free end of the spring piece 29 is in an arc structure and slides in the corresponding groove 28. When the fiber strip coil is sleeved, the spring piece 29 is extruded, and then through the movement of the clamping plate 22, the spring piece 29 is extruded and deformed into the groove 28. Due to the arc structure of the free end of the spring piece 29, the end part of the spring piece 29 that is deformed under pressure is easy to move, extending the service life of the spring piece 29.

[0045] Embodiment Two: Please refer to Figure 1 、 Figure 3 、 Figure 4 And Figures 6 - 8As shown in the figure, in view of the problem that it is difficult to adjust the feeding tension of the fiber strip in real time to ensure that the feeding tension is always in an ideal state, the following solutions can be adopted;

[0046] In this embodiment, an air outlet hole 18 communicating with the inside of the corresponding rotating sleeve 21 is formed on the air outlet pipe 12, and an electromagnetic control valve is installed in the air outlet hole 18. The electromagnetic control valve is used to separately control the air pressure value inside the corresponding rotating sleeve 21, and combined with the movement of the main piston block 111 in the cylinder sleeve 19, the adjustment of the independent damping turning force is realized. A cylinder sleeve 19 is fixedly connected to the fixing seat 1, and a support plate is fixedly connected to the inside of the cylinder sleeve 19. One side of the support plate is provided with a main piston block 111 sliding with the cylinder sleeve 19 through an electric push rod 110. An air inlet pipe is fixedly connected between the cylinder sleeve 19 and the air outlet pipe 12.

[0047] A cross plate 33 is fixedly connected to the fixing seat 1, and a U-shaped frame 34 is slidably connected to the cross plate 33. A bracket 35 for rotating the corresponding pressing wheel 32 is fixedly connected to the U-shaped frame 34. The U-shaped frame 34 and the bracket 35 are used to realize the adjustable installation of the pressing wheel 32. A pushing plate 37 sliding with the U-shaped frame 34 is fixedly connected to the bracket 35 through a second spring 36. A pressure sensor in contact with the corresponding pushing plate 37 is installed on the cross plate 33. During the tight feeding process of the fiber strip during unwinding, the pressing wheel 32 is driven to rise and compress the second spring 36, and the pushing plate 37 is lifted by the elastic force of the second spring 36;

[0048] When the feeding tension of the fiber strip is too large, the corresponding pressing wheel 32 is urged to further rise and move by squeezing the second spring 36. When the feeding tension of the fiber strip is too small, the corresponding second spring 36 is urged to push the pressing wheel 32 to reset and descend. The set pressure sensor collects real-time data on the upward extrusion force of the pushing plate 37 and transmits the collected data obtained by detection to the controller in the control panel 11;

[0049] The controller compares and analyzes the collected data with the set data. When the collected data of the pressure sensor is greater than the set data, the controller generates a control signal to control the opening of the electromagnetic control valve in the corresponding rotating sleeve 21 and drives the piston rod of the electric push rod 110 to contract, reducing the air pressure value in the rotating sleeve 21. Combined with the reset of the piston ring 14 carried by the reset tension spring 17, the contact force between the corresponding second resistance ring 13 and the first resistance ring 23 is reduced;

[0050] When the collected data of the pressure sensor is less than or equal to the set data, the corresponding electromagnetic control valve is opened, and the piston rod of the electric push rod 110 extends, further increasing the air pressure value in the rotating sleeve 21 and increasing the contact force between the corresponding second resistance ring 13 and the first resistance ring 23, thereby automatically adjusting the tension of the fiber strip during feeding and improving the production quality of linen.

[0051] An annular limiting groove equal in number to the rotating sleeve 21 is provided on the annular outer wall of the guide roller 31 for anti-deviation guiding treatment of the fiber strip. A limiting plate 38 is fixedly connected to the fixed seat 1, and an anti-deviation hole matching the corresponding annular limiting groove is provided on the limiting plate 38. The free end of the fiber strip first passes through the corresponding anti-deviation hole, and then is discharged and output after being guided by two groups of guide rollers 31 and the corresponding pressure rollers 32. The provided anti-deviation hole is used to avoid the problem that the position of the fiber strip continuously changes during winding and unwinding, resulting in separation from the annular limiting groove.

[0052] Embodiment 3: Please refer to Figures 1 - 8 As shown, the present invention also proposes a usage method of a controllable feeding component for processing raw materials in linen cloth production, including the following steps:

[0053] Step 1: A plurality of fiber strip rolls for linen cloth production are sequentially sleeved on the outside of the corresponding rotating sleeves 21. The sleeved fiber strip rolls are preliminarily fixed by the spring pieces 29 on the clamping plates 22 to maintain the placement position of the fiber strip rolls before fixation. Then, the control panel 11 is used to control the piston rod of the electric push rod 110 to extend, prompting the main piston block 111 to slide in the cylinder sleeve 19. The gas in the cylinder sleeve 19 is injected into the air outlet pipe 12 through the air inlet pipe, and then injected into the corresponding rotating sleeve 21 through a plurality of air outlet holes 18.

[0054] Then, a plurality of auxiliary piston blocks 25 are pushed to synchronously carry the corresponding mounting plates 26 to move, causing the clamping plates 22 to contact the inner wall of the fiber strip roll. Through the rotational connection between the mounting plate 26 and the clamping plate 22, each clamping plate 22 is adaptively fitted and abutted against the conical or cylindrical inner wall of the fiber strip roll, and the spring piece 29 is squeezed and deformed into the groove 28 to complete the stable clamping of the fiber strip roll.

[0055] Step 2: The main piston block 111 continues to move in the cylinder sleeve 19. By virtue of the abutment between the clamping plate 22 and the inner wall of the fiber strip roll, the position of the auxiliary piston block 25 is restricted. The gas in the rotating sleeve 21 accumulates to push the piston ring 14 to stretch and reset the tension spring 17 to move, causing the piston ring 14 to carry the resistance ring II 13 to contact the resistance ring I 23, completing the damping rotation of each rotating sleeve 21, and stopping the movement of the piston rod of the electric push rod 110 and closing the electromagnetic control valves on each air outlet hole 18.

[0056] Step 3: The free end of the fiber strip on the fiber strip roll passes through the corresponding anti-deviation hole, and is discharged and output after being guided by two groups of guide rollers 31 and the corresponding pressure rollers 32. Combining with the damping rotation of the rotating sleeve 21, the fiber strip roll is subjected to tight feeding treatment during the feeding process, and drives the pressure roller 32 to rise and compress the spring II 36. Through the elastic force of the spring II 36, the push plate 37 is pushed to rise. The pressure sensor installed between the push plate 37 and the cross plate 33 collects data on the upward extrusion force of the push plate 37, and transmits the detected collected data to the controller in the control panel 11.

[0057] The controller compares and analyzes the collected data with the set data. When the feeding tension of a certain fiber strip is too large, it causes the corresponding pressing wheel 32 to squeeze the second spring 36 to move further upward, resulting in the collected data of the pressure sensor being greater than the set data. The controller generates a control signal to control the opening of the electromagnetic control valve in the corresponding rotating sleeve 21, and drives the piston rod of the electric push rod 110 to contract, reducing the air pressure value in the rotating sleeve 21. Combining with the reset of the piston ring 14 carried by the reset tension spring 17, the contact force between the corresponding second resistance ring 13 and the first resistance ring 23 is reduced;

[0058] When the feeding tension of a certain fiber strip is too small, it causes the corresponding second spring 36 to push the pressing wheel 32 to reset and move downward, resulting in the collected data of the pressure sensor being less than or equal to the set data. The controller generates a control signal to control the opening of the electromagnetic control valve in the corresponding rotating sleeve 21, and drives the piston rod of the electric push rod 110 to extend, further increasing the air pressure value in the rotating sleeve 21, increasing the contact force between the corresponding second resistance ring 13 and the first resistance ring 23, and then automatically regulating the magnitude of the tension during the feeding of the fiber strip, improving the production quality of linen.

[0059] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
