Description

Technical Field

[0001] The present application relates to the technical field of linen processing equipment, and specifically to a linen spreading machine with large and small piece switching and a brush processing device. Background Art

[0002] Linen spreading machines are key equipment in the linen washing industry. Common types include mechanical and pneumatic. Mechanical ones rely on motors to drive mechanical structures to grab, move and spread linens, while pneumatic ones use compressed air to push components to operate. Its main function is to initially spread linens to facilitate subsequent processes.

[0003] The existing linen processing equipment has a relatively simple design concept and is too targeted in its functions. It can often only focus on processing linens within a certain size range. For example, most equipment is only good at processing large linens such as bed sheets and quilt covers, or can only work on small linens such as pillowcases, napkins, and tablecloths. It lacks the ability to flexibly switch between linens of different sizes. This limitation greatly limits the applicable scenarios of the equipment. In actual applications, if there are multiple different specifications of linens that need to be processed at the same time in the linen processing site, it is necessary to purchase multiple different types of equipment, which not only greatly increases the equipment procurement cost, but also occupies a large amount of space resources, making the linen processing work extremely inconvenient and the overall operational efficiency low.

[0004] From the perspective of treatment effect, the existing equipment is too simple and crude when dealing with the problem of wrinkles on the surface of linens. The common treatment method is to rely on simple pulling or rolling, which is unable to perform all-round and refined flattening operations on the linens. This results in the linens still being difficult to meet high standards of flatness requirements after treatment. The insufficient flatness of the linens will trigger a series of chain reactions in subsequent key processes such as ironing and folding. During the ironing process, uneven linens will be heated unevenly, and some areas may not be fully ironed, thus affecting the overall ironing quality; in the folding process, the presence of wrinkles will make the folding size inaccurate, affecting the neatness and aesthetics of the folding, seriously reducing the quality and efficiency of subsequent processes, and thus affecting the continuity of the entire linen processing process and the quality of the final product.

[0005] Therefore, it is necessary to provide a linen spreading machine with large and small piece switching and a brush processing device to solve the above problems.

[0058] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0059] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present application.

[0060] See also Figure 1-12 , the embodiment provided by the present invention:

[0061] like Figure 1-3 As shown, a linen spreading machine with large and small piece switching and brush processing device includes a frame 1, one side of the frame 1 is a linen feeding place, and the other side of the frame 1 is a linen discharging place. A four-station feeding device 2 for manually installing linens is installed on the top of the frame 1 at the linen feeding place. The four-station feeding device 2 provides large pieces of linens for the spreading device 4.

[0062] Specifically, Figure 4 and Figure 5 As shown, the four-station loading device 2 includes an angle adjustment component and a cloth clamping component 23. The angle adjustment component includes a first bracket 21 and an angle adjustment cylinder 22. The two ends of the first bracket 21 are hinged to the two sides of the top of the frame 1 located at the linen feeding position through hinges. The two sides of the top of the first bracket 21 are respectively hinged with angle adjustment cylinders 22, and the tail of the angle adjustment cylinder 22 is fixedly installed on the top surface of the frame 1. Four cloth clamping components 23 are respectively installed on the inner side of the first bracket 21.

[0063] In the angle adjustment assembly, the angle adjustment cylinder 22 is electrically connected to the control system. When receiving the control signal, the piston inside the angle adjustment cylinder 22 performs linear reciprocating motion under the action of air pressure. By extending or retracting the piston rod, the first bracket 21 is pushed to rotate clockwise or counterclockwise around its hinge point with the frame 1. This rotation can change the inclination angle of the first bracket 21 to adapt to the working habits of different operators and the optimal angle for placing linens.

[0064] The cloth clamping assembly 23 includes a support frame 231, a round waist guide rail 232, a rotating frame 233, a clamp 234, a first motor 235, a rotating rod 236 and a sprocket chain mechanism 237. The support frame 231 is respectively installed on the inner side of the first bracket 21, the round waist guide rail 232 is respectively fixedly installed on the inner side walls of the support frame 231, and the two ends of the rotating frame 233 are slidably connected on the round waist guide rail 232 through guide wheels. The bottom surface of the rotating frame 233 is respectively fixedly installed with clamps 234 for clamping the two ends of large pieces of linen.

[0065] A first motor 235 is fixedly installed on one side of the support frame 231, and the first motor 235 is connected to the rotating rod 236 through a gearbox. Both ends of the rotating rod 236 are rotatably connected inside the support frame 231 through bearings. The side wall key of the rotating rod 236 is connected to a sprocket chain mechanism 237, and the chain of the sprocket chain mechanism 237 is hingedly installed on the top of the rotating frame 233.

[0066] In the cloth clamping assembly 23, after the first motor 235 is powered on, its rotor starts to rotate. The output shaft of the motor is connected to the input shaft of the gearbox through a coupling, and the gearbox adjusts the speed of the motor to meet the actual working requirements of the cloth clamping assembly 23. The adjusted power is transmitted to the rotating rod 236, and the two ends of the rotating rod 236 are installed inside the support frame 231 through high-precision bearings to ensure that the rotating rod 236 can rotate flexibly. The sprocket chain mechanism 237 is keyed to the side wall of the rotating rod 236, and when the rotating rod 236 rotates, the sprocket is driven to rotate synchronously. The sprocket and the chain are meshed with each other. Since the other end of the chain is hingedly installed with the top of the rotating frame 233, the movement of the chain causes the rotating frame 233 to rotate on the round waist guide rail 232. Guide wheels are installed at both ends of the rotating frame 233, and the guide wheels roll on the round waist guide rail 232, which reduces the friction when the rotating frame 233 moves and ensures the stability of the movement of the rotating frame 233. A clamp 234 is fixedly installed on the bottom surface of the rotating frame 233. As the rotating frame 233 moves, the clamp 234 can be accurately moved to the placement position of the large piece of linen. Manually, through the clamping mechanism inside the clamp 234, such as a spring, a lever and other devices, the two ends of the large piece of linen are firmly clamped and transported into the interior of the frame 1, which facilitates manual installation of the large piece of linen and significantly improves the loading efficiency.

[0067] A spreading device 4 for feeding large pieces of linen and a lower feeding device 3 for feeding small pieces of linen are fixedly installed on one side of the interior of the frame 1 at the linen feeding place. The interior of the frame 1 is divided into two regional feeding stations of an upper feeding port 8 and a lower feeding port 9 by the spreading device 4 and the lower feeding device 3;

[0068] When loading large pieces of linen:

[0069] like Figure 6 and Figure 7 As shown, the spreading device 4 includes a second bracket 41, a position adjustment mechanism installed on both sides of the second bracket 41, and a clamping mechanism installed on the position adjustment mechanism;

[0070] The position adjustment mechanism includes a second motor 42 and a synchronous belt synchronous wheel mechanism 43. The second motor 42 is respectively mounted on the side walls of the second bracket 41. The second bracket 41 is fixedly mounted inside the frame 1. The second bracket 41 is rotatably connected with the synchronous belt synchronous wheel mechanism 43. The output shaft of the second motor 42 is transmission-connected to the synchronous belt synchronous wheel mechanism 43 through a transmission mechanism.

[0071] The clamping mechanism includes a moving frame 44, a first cylinder 45 and a cloth clamp 46. One end of the moving frame 44 is fixedly mounted on the synchronous belt side wall of the synchronous belt synchronous wheel mechanism 43. A pulley 48 is fixedly mounted on the inner side wall of the moving frame 44. A slide groove 47 is provided inside the second bracket 41. The moving frame 44 also slides in the slide groove 47 through the pulley 48 and moves on the side wall of the second bracket 41. The first cylinder 45 is fixedly mounted on the outer side wall of the moving frame 44. A cloth clamp 46 for receiving the cloth clamping assembly 23 and conveying it to the large piece of linen is installed at the bottom of the moving frame 44.

[0072] The output shaft of the first cylinder 45 is hinged to the tail of the upper clamping plate of the cloth clamp 46, the lower clamping plate of the cloth clamp 46 is fixedly installed to the moving frame 44, and the upper clamping plate is hinged to the lower clamping plate.

[0073] The second motor 42 is connected to the electrical control system. When the control system issues a start command, the output shaft of the second motor 42 is connected to the driving wheel in the synchronous belt synchronous wheel mechanism 43 through a transmission mechanism such as a belt, a chain or a gear, and the power of the motor is transmitted to the synchronous belt synchronous wheel mechanism 43. The synchronous belt synchronous wheel mechanism 43 is composed of a driving wheel, a driven wheel and a synchronous belt. The driving wheel rotates under the drive of the motor, and the friction between the synchronous belt and the driven wheel drives the driven wheel to rotate synchronously, thereby realizing the circulation of the synchronous belt inside the second bracket 41. One end of the mobile frame 44 is fixedly mounted on the side wall of the synchronous belt. When the synchronous belt moves, it drives the mobile frame 44 to make a horizontal linear motion on the second bracket 41. A plurality of pulleys 48 are installed on the inner side wall of the mobile frame 44, and a slide groove 47 is opened at the corresponding position inside the second bracket 41. The pulley 48 rolls in the slide groove 47, which not only provides a guiding effect for the movement of the mobile frame 44, but also reduces the friction between the mobile frame 44 and the second bracket 41, so that the movement of the mobile frame 44 is smoother.

[0074] The first cylinder 45 is connected to the control system. When the opening and closing of the cloth clamp 46 needs to be controlled, the control system sends a signal to the first cylinder 45. The piston inside the first cylinder 45 moves under the action of hydraulic pressure or gas pressure. The upper clamping plate of the cloth clamp 46 is pushed to rotate around the hinge point with the lower clamping plate by extending or retracting the piston rod. The upper clamping plate and the lower clamping plate are hinged by means of a pin shaft, etc. The lower clamping plate is fixedly mounted on the mobile frame 44, so that the cloth clamp 46 can be opened and closed, so as to clamp the large piece of linen fed into the four-station feeding device 2, and then the two ends of the large piece of linen are pulled apart by the position adjustment mechanism. By controlling the moving speed, direction and distance of the mobile frame 44, the linen can be accurately unfolded, thereby realizing the unfolding process of the linen.

[0075] like Figure 3 As shown, the lower feeding device 3 manually lays small pieces of linen, and the lower feeding device 3 includes a conveying mechanism for transporting small pieces of linen and an extension mechanism for extending the conveying mechanism, and the conveying mechanism includes a first guide frame 31 and a first roller 33, the first guide frame 31 is slidably connected inside the frame 1 through a slide rail mechanism, and the two sides of the guide frame are rotatably connected with the first rollers 33 respectively, and the top surface of the first guide frame 31 is connected to a plurality of first conveyor belts for transporting small pieces of linen through the first rollers 33;

[0076] The extension mechanism includes an electric push rod 32 and a conveyor belt tension adjustment mechanism 34. The tail of the electric push rod 32 is fixedly mounted on the inner wall of the frame 1. The end of the telescopic shaft of the electric push rod 32 is hinged to both sides of one end of the first material guide frame 31. The conveyor belt tension adjustment mechanism 34 is installed inside the frame 1 below the first material guide frame 31. The first conveyor belt is wound around the guide wheel of the conveyor belt tension adjustment mechanism 34.

[0077] Before the operator manually lays the small piece of linen on the first conveyor belt, the operator extends the piston rod of the electric push rod 32. When the piston rod moves, the first guide rack 31 is pushed to slide linearly along the slide rail mechanism inside the frame 1, thereby adjusting the position of the first guide rack 31, so that the first guide rack 31 is extended from the frame 1, so that the operator can manually lay the small piece of linen on the first conveyor belt, and then retract the piston rod of the electric push rod 32 to retract the first guide rack 31, which can flexibly meet the feeding needs of small pieces of linen of different specifications.

[0078] The first conveyor belt rotates to deliver the small pieces of linen into the interior of the fabric advancer.

[0079] The frame 1 is located at one side of the linen discharge point, and a lower feeding device 7 and an upper feeding device 10 are fixedly installed therein. The gap between the lower feeding device 7 and the upper feeding device 10 is a linen transportation area, and the linen transportation area is the confluence of the discharge points of the upper feed port 8 and the lower feed port 9;

[0080] A cloth brushing device 5 for cleaning the surface of linens is installed inside the frame 1 between the lower feeding device 7 and the cloth spreading device 4 .

[0081] Specifically, Fig. 9 , Fig.10 and Fig.11 As shown, the cloth brushing device 5 includes a third bracket 51, an inner brush mechanism and an outer brush mechanism. The third bracket 51 is fixedly installed inside the frame 1. The side wall of the third bracket 51 is rotatably connected to the inner brush mechanism. The top of the third bracket 51 is slidably connected to the outer brush mechanism. The inner brush mechanism and the outer brush mechanism are arranged opposite to each other.

[0082] The inner brush mechanism includes a first rotating wheel 52, an inner brush cloth 53 and a fourth motor 510. The side walls of the third bracket 51 are rotatably connected to two first rotating wheels 52, the two first rotating wheels 52 are transmission-connected through the inner brush cloth 53, and the first rotating wheel 52 near the outer side of the third bracket 51 is transmission-connected to the output shaft of the fourth motor 510.

[0083] The output shaft of the fourth motor 510 is connected to the first rotating wheel 52 in the inner brush mechanism through a transmission device such as a coupling or a pulley, and transmits power to the first rotating wheel 52. The first rotating wheel 52 is mounted on the side wall of the third bracket 51 and is flexibly rotated through a bearing. Driven by the fourth motor 510, the first rotating wheel 52 starts to rotate. Since the first rotating wheel 52 and the inner brush cloth 53 interact through friction, the rotation of the first rotating wheel 52 drives the inner brush cloth 53 to circulate.

[0084] The outer brush mechanism includes a linear guide 54, a slide 55, a carriage 56, a third motor 57, a second rotating wheel 58 and an outer brush cloth 59. The linear guide 54 is fixedly installed on the top surface of the third bracket 51, the slide 55 is slidably connected on the linear guide 54, the carriage 56 is fixedly installed on the top surface of the slide 55, the top of one side of the carriage 56 is fixedly installed with the third motor 57, the inner sides of the carriage 56 are respectively rotatably connected with the second rotating wheels 58, the two second rotating wheels 58 are transmission-connected through the outer brush cloth 59, and the output shaft of the third motor 57 is transmission-connected with one of the second rotating wheels 58;

[0085] The output shaft of the third motor 57 is connected to one of the second rotating wheels 58 in the outer brush mechanism through a transmission device, driving the second rotating wheel 58 to rotate. A linear guide 54 is fixedly installed on the top surface of the third bracket 51, and the slide 55 cooperates with the linear guide 54 through a slider, and can slide linearly on the linear guide 54. The slide 56 is fixedly installed on the top surface of the slide 55 and moves with the movement of the slide 55. Second rotating wheels 58 are respectively installed on both sides of the inner part of the slide 56 through bearings, and the two second rotating wheels 58 are connected by transmission through the outer brush cloth 59. When the third motor 57 drives one of the second rotating wheels 58 to rotate, the other second rotating wheel 58 is driven to rotate synchronously through the outer brush cloth 59, so as to realize the circular motion of the outer brush cloth 59.

[0086] The two sides of the large piece of linen slide between the outer brush cloth 59 and the inner brush cloth 53. During the transportation process, the large piece of linen is guided by the guide device so that the two sides pass between the outer brush cloth 59 and the inner brush cloth 53. Because the inner brush cloth 53 and the outer brush cloth 59 move relative to each other under the drive of the motor, and there is friction between the linen and the brush cloth, the brush cloth wipes the surface of the linen during the movement, thereby cleaning the debris, dust, etc. on the surface of the linen, and at the same time, the friction and movement of the brush cloth are used to preliminarily sort out the wrinkles on the surface of the linen.

[0087] like Fig. 9 As shown, the lower feeding device 7 includes a second roller 71, a second conveyor belt 72 and a vacuum bin 73. A material guide plate is provided at the tail of the vacuum bin 73. The side wall of the vacuum bin 73 is rotatably connected to the second conveyor roller. The side wall of the material guide plate is rotatably mounted with the second roller 71. The second conveyor belt 72 is rotatably connected on the vacuum bin 73 and the material guide plate through two second conveyor rollers. A plurality of suction holes for air suction are provided on the top surface of the vacuum bin 73. The bottom side wall of the vacuum bin 73 is connected to the vacuum device 6 through a pipeline.

[0088] The vacuum device 6 is usually composed of a vacuum pump, a vacuum pipe and other components. When the vacuum device 6 is started, the vacuum pump starts to work, and is connected to the vacuum chamber 73 through the vacuum pipe, and the air in the vacuum chamber 73 is extracted, so that a negative pressure environment is formed in the vacuum chamber 73. A plurality of suction holes are evenly opened on the top surface of the vacuum chamber 73. Under the action of negative pressure, the outside air quickly flows into the vacuum chamber 73 through the suction holes. Since the linens are placed on the second conveyor belt 72 and are located above the suction holes, the flow of air produces a strong adsorption force on the linens, so that the linens are tightly attached to the second conveyor belt 72.

[0089] The second rollers 71 are respectively mounted on the side walls of the vacuum bin 73 and the side walls of the guide plate, and are flexibly rotated by bearings. The second conveyor belt 72 is sleeved on the two second rollers 71, and the motor drives one of the second rollers 71 to rotate through the transmission device, and the friction between the conveyor belt and the roller is used to drive the second conveyor belt 72 to circulate, thereby transporting the linens smoothly. The guide plate is fixedly mounted at the tail of the vacuum bin 73, and its surface is designed with a certain inclination angle and smooth material, which can accurately guide the transportation direction of the linens and ensure that the linens are sent out from the equipment along the predetermined path.

[0090] like Fig.12 As shown, the upper feeding device 10 includes a suspension 101, a second cylinder 102, a conveyor belt mechanism 103, a fifth motor 104 and a guide plate 105. The suspension 101 is fixedly mounted on the inner top surface of the frame 1 and is located above the lower feeding device 7. The guide plate 105 is hingedly mounted at the end of the suspension 101. Both sides of the top surface of the guide plate 105 are hinged to the telescopic shaft of the second cylinder 102. The tail of the second cylinder 102 is fixedly mounted on the suspension 101. The bottom of the suspension 101 is rotatably connected with the conveyor belt mechanism 103. The conveyor belt mechanism 103 is driven by the fifth motor 104 and rotates on the suspension 101. The output shaft of the fifth motor 104 is connected to the conveyor belt mechanism 103 through a transmission device such as a coupling, a gear box or a pulley to transmit power to the conveyor belt mechanism 103. At the same time, the suspension 101 is fixedly mounted on the inner top surface of the frame 1 and is located above the lower feeding device 7. Its end is hinged to the guide plate 105 by a hinge or the like. The second cylinder 102 is connected to the control system. When the control system issues an angle adjustment command, the piston inside the second cylinder 102 moves under the action of hydraulic pressure or gas pressure, and the guide plate 105 is pushed to rotate clockwise or counterclockwise around the hinge point with the suspension 101 by extending or retracting the piston rod, so as to flexibly adjust the angle of the guide plate 105. During the transportation process, the linens are first guided by the guide plate 105 and smoothly transferred to the conveyor belt according to the inclination angle of the guide plate 105. Then, as the conveyor belt rotates, the conveyor belt mechanism 103 conveys the linens out of the equipment, further facilitating the conveying operation of the linens.
