Description

Technical Field

[0001] The present application relates to the technical field of cloth laying machines, and particularly to an automatic cloth laying machine capable of switching between cloth sucking and cloth blowing. Background Art

[0002] As an important device in the field of textile machinery, the automatic cloth laying machine plays a key role in scenarios such as clothing manufacturing and home textile production. When centrally cutting fabrics, it is necessary to stack the fabrics. With the continuous improvement of the cutting accuracy requirements, the functional requirements of the automatic cloth laying machine have become increasingly complex.

[0003] Currently, when laying and stacking fabrics flat, one end of the fabric is clamped by a clamping device, and the clamping device pulls the fabric to move until it reaches the blowing area at the top of the operating table. The clamping device places the fabric so that the fabric lies flat on the operating table. Subsequently, the above actions are repeated until the fabric stacking is completed. When the fabric is laid flat again and the fabric is held by the clamping device, after the fabric is laid flat, an upward airflow is generated by the blower at the bottom of the platform to make the fabric float for easy movement. However, when laying the fabric flat, the fabric lies freely on the operating table of the cloth laying machine, and the fabric is likely to wrinkle, thereby reducing the quality of the stacked fabric. Summary of the Invention

[0004] In order to improve the quality of fabric stacking, the present application provides an automatic cloth laying machine capable of switching between cloth sucking and cloth blowing.

[0005] The automatic cloth laying machine capable of switching between cloth sucking and cloth blowing provided by the present application adopts the following technical solutions: An automatic cloth laying machine capable of switching between cloth sucking and cloth blowing, comprising: A pump assembly; An operating table, the top wall of which is penetrated with a plurality of air holes; A pipeline switching mechanism, including a shunt pipeline, a cloth sucking channel, a cloth blowing channel and a switching component. The shunt pipeline is a T-shaped tee structure. The main pipeline of the shunt pipeline is connected to the output end of the pump assembly, and the two branch pipelines of the shunt pipeline are respectively connected to the cloth sucking channel and the cloth blowing channel. The switching component is used to conduct and switch between the cloth sucking channel and the cloth blowing channel.

[0006] By adopting the above technical solutions, the rapid switching between the cloth sucking and cloth blowing functions can be achieved by a single pump, significantly reducing the equipment cost. The design of the T-shaped tee structure of the shunt pipeline ensures the efficient switching of the airflow between the cloth sucking channel and the cloth blowing channel, reducing the airflow loss and improving the reliability of the system. The combined use of the pump assembly and the pipeline switching mechanism enables the fabric to be firmly adsorbed or easily blown during the laying process, effectively reducing the movement or wrinkling of the fabric, and improving the fabric stacking quality and operation efficiency.

[0007] Optionally, clamping components are provided at both ends of the operating table, and the two clamping components respectively clamp the two ends of the fabric.

[0008] By adopting the above technical solution, the clamping components can respectively clamp the two ends of the fabric, effectively reducing the displacement or wrinkling of the fabric during the process of sucking or blowing the fabric, thereby improving the flatness and stability of the fabric laying and further enhancing the fabric stacking quality.

[0009] Optionally, the operating table includes a frame, an operating board, a bending board, a first elastic member, and a limiting board. The operating board is fixed on the top of the frame. The bending boards are symmetrically arranged at both ends of the operating board. One end of the first elastic member is connected to the bottom of the bending board, and the end of the first elastic member away from the bending board is connected to the limiting board. The bending board is bent relative to the operating board through the clamping component.

[0010] By adopting the above technical solution, the bending board is bent relative to the operating board through the clamping component. Combining with the elastic support of the first elastic member, it can effectively reduce the displacement or wrinkling of the fabric during the process of sucking or blowing the fabric. The setting of the bending board enables the fabric to be clamped and pulled at the same time, further reducing the fabric stacking quality.

[0011] Optionally, the bending board includes an inclined portion and a bending portion. The thickness of the inclined portion is greater than the thickness of the bending portion. The inclined portion is connected to the bending portion. The end of the bending portion away from the inclined portion is connected to the operating board. The first elastic member is connected to the inclined portion.

[0012] By adopting the above technical solution, the bending board is composed of an inclined portion and a bending portion with different thicknesses. The larger thickness of the inclined portion provides higher structural strength, which can effectively reduce excessive deformation of the bending board under the action of the clamping component. The thinner design of the bending portion enables it to be bent flexibly under the pulling of the first elastic member, thereby realizing stable clamping of the fabric, not only improving the clamping effect but also reducing the fabric wrinkling problem caused by insufficient clamping force, and further enhancing the stacking quality.

[0013] Optionally, the clamping component includes a clamping member, a second elastic member, a sliding column, a rotating member, and a rotation driving member. The clamping member is hinged to the bending board. The second elastic member is used to make the clamping member clamp on the top wall of the bending board. One side of the clamping member is connected to the sliding column. The rotating member is rotatably connected to the frame. The rotating member is provided with a sliding groove. The sliding column is inserted into the sliding groove. The rotating member pushes the sliding column to slide through the rotation driving member.

[0014] By adopting the above technical solution, the sliding column cooperates with the sliding groove. The sliding column is pushed to slide through the rotation driving member to realize the opening and closing action of the clamping member. The operation is convenient and reliable. When continuously rotating, the rotating force of the rotating member pushes the bending board, thereby causing the bending board to bend and improving the convenience.

[0015] Optionally, the clamping member includes a hinge portion, a clamping portion, and a support portion. The hinge portion is hinged to the bent plate, the hinge portion is connected to the clamping portion, the hinge portions are symmetrically arranged at both ends of the clamping portion, the support portion is arranged between the two hinge portions, and the support portion is connected to the hinge portion. When the clamping portion clamps the fabric, the top wall of the support portion and the top wall of the operation plate are located on the same horizontal plane.

[0016] By adopting the above technical solution, the top wall of the support portion and the top wall of the operation plate are kept on the same horizontal plane, so that when the fabric is stacked, it can be laid flat on the same horizontal plane, effectively reducing the phenomenon of wrinkles or unevenness of the fabric during the clamping process.

[0017] Optionally, there is a gap between one end of the support portion away from the clamping portion and the bent plate.

[0018] By adopting the above technical solution, there is a gap between the support portion of the clamping assembly and the bent plate, so that the clamping assembly can better adapt to the thickness change of the fabric when clamping the fabric, reducing the possibility of uneven clamping force caused by structural interference, improving the versatility and stability of the clamping assembly, ensuring that fabrics of different thicknesses can be firmly clamped, and thus further improving the flatness of fabric laying and the cutting accuracy.

[0019] Optionally, the air holes are arranged in a rectangular array on the operation table.

[0020] By adopting the above technical solution, the air holes are arranged in a rectangular array on the operation table, making the air flow distribution more uniform, effectively improving the stability of the fabric suction and blowing functions. In the fabric suction mode, the air holes in the rectangular array can form a more uniform negative pressure area to ensure that the fabric is adsorbed flat and reduce the generation of wrinkles; in the fabric blowing mode, the air hole array design makes the air flow spout more uniformly, facilitating the stable movement of the fabric and improving the accuracy of position adjustment.

[0021] Optionally, an air storage box is connected to the bottom of the operation table, the fabric suction channel is connected to the air storage box, and the fabric blowing channel is connected to the air storage box.

[0022] By adopting the above technical solution, the setting of the air storage box can effectively integrate the air flow distribution of the fabric suction channel and the fabric blowing channel, ensure the uniform distribution of the air flow at the bottom of the operation table, improve the stability of the adsorption force during fabric suction, and also enhance the uniformity of the air flow during fabric blowing, thereby further improving the flatness of fabric laying and the accuracy of position adjustment.

[0023] Optionally, the switching assembly includes a switching cylinder, a push rod, and a push driving member. The switching cylinder is slidably connected to the intersection of the shunt pipelines. The switching cylinder is provided with a fabric blowing port and a fabric suction port. The push rod is connected to the switching cylinder, the push driving member is connected to the operation table, and the output end of the push driving member is connected to the push rod.

[0024] By adopting the above technical solution, the switching cylinder slides along the intersection of the shunt pipelines under the drive of the push rod and the push driving member, so as to accurately direct the air flow to the cloth suction channel or the cloth blowing channel, improve the switching speed, ensure the efficient utilization of the air flow, and reduce the air flow loss. In addition, since special cloth blowing ports and cloth suction ports are provided on the switching cylinder, the accuracy of the air flow direction is further ensured, so that the device can firmly adsorb the cloth in the cloth suction mode and can smoothly blow the cloth in the cloth blowing mode, effectively meeting the diverse requirements of the automatic cloth laying machine for cloth processing.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. It can realize the rapid switching of the functions of cloth suction and cloth blowing with a single pump, significantly reducing the equipment cost. The design of the shunt pipeline with a T-shaped tee ensures the efficient switching of the air flow between the cloth suction channel and the cloth blowing channel, reduces the air flow loss, and improves the reliability of the system. The combined use of the pump assembly and the pipeline switching mechanism enables the cloth to be firmly adsorbed or easily blown during the laying process, effectively reducing the movement or wrinkling of the cloth and improving the stacking quality and operation efficiency of the cloth; 2. The bending plate is bent on the operation plate through the clamping assembly. Combining with the elastic support of the first elastic member, it can effectively reduce the displacement or wrinkling of the cloth during cloth suction or cloth blowing.

The sliding column cooperates with the sliding groove. The sliding column is pushed to slide by the rotary driving member to realize the opening and closing action of the clamping member.

[0030] The following is further detailed description of this application in combination with the attached Figures 1-3 drawings.

[0031] The embodiment of this application discloses an automatic fabric laying machine with switchable fabric suction and blowing.

[0032] Referring to Figure 1 and Figure 2 , an automatic fabric laying machine with switchable fabric suction and blowing includes a pump unit assembly 1, an operating console 2 and a pipeline switching mechanism. A plurality of air holes 221 are penetrated and opened on the top wall of the operating console 2. The pipeline switching mechanism includes a diverting pipeline 3, a fabric suction channel 31, a fabric blowing channel 32 and a switching assembly 33. The diverting pipeline 3 is a T-shaped tee structure. The main pipeline of the diverting pipeline 3 is connected to the output end of the pump unit assembly 1. The two branch pipes of the diverting pipeline 3 are respectively connected to the fabric suction channel 31 and the fabric blowing channel 32. The switching assembly 33 is used to conduct and switch between the fabric suction channel 31 and the fabric blowing channel 32. The combined use of the pump unit assembly 1 and the pipeline switching mechanism enables the fabric to be firmly adsorbed or easily blown during the laying process, effectively reducing the movement or wrinkling of the fabric and improving the stacking quality and operation efficiency of the fabric. In this example, the pump unit assembly 1 uses a turbine fan.

[0033] The air holes 221 are arranged in a rectangular array on the top of the operating console 2, making the air flow distribution more uniform. The operating console 2 includes a frame 21 and an operating panel 22. The operating panel 22 is fixedly connected to the top of the frame 21. The air holes 221 are opened on the top wall of the operating panel 22. The bottom wall of the operating console 2 is fixedly connected with an air chamber 24. The top wall of the air chamber 24 is provided with an air chamber. The air holes 221 communicate with the air chamber. The fabric suction channel 31 is fixedly connected with the air chamber 24, and the fabric blowing channel 32 is fixedly connected with the air chamber 24, integrating the air flow distribution of the fabric suction channel 31 and the fabric blowing channel 32, ensuring uniform air flow distribution at the bottom of the operating console 2, and improving the adsorption force stability during fabric suction.

[0034] The outer wall at the intersection of the shunt pipe 3 is provided with a pushing groove. The switching assembly 33 includes a switching cylinder 331, a pushing rod 332 and a pushing driving member 333. The pushing rod 332 is inserted into the pushing groove. The opposite sides of the pushing rod 332 are in contact with the pushing rod 332. The pushing rod 332 is fixedly connected to the outer wall of the switching cylinder 331. The switching cylinder 331 is slidably connected to the intersection of the shunt pipe 3 through the pushing rod 332. One end of the switching cylinder 331 away from the pushing groove is provided with a cloth blowing port and a cloth sucking port. The switching cylinder 331 is in a T shape. The pushing driving member 333 is fixedly connected to the operation plate 22. The output end of the pushing driving member 333 is fixedly connected to the pushing rod 332. In this embodiment, the pushing driving member 333 adopts a cylinder.

[0035] When the cloth is placed on the operation plate 22, the cloth sucking mode is turned on. Specifically, the pushing driving member 333 drives the pushing rod 332 to slide in a fixed direction along the pushing groove, connecting the cloth sucking port with the main pipe of the shunt pipe 3. Thus, the output end of the pump assembly 1, the air suction channel, the cloth sucking port, the air chamber and the air hole 221 form a circulation path. The pump assembly 1 is started, and the negative pressure air flow generated by the pump assembly 1 flows through the shunt pipe 3, the cloth suction channel 31, the air chamber 24 and the air hole 221 in sequence, forming an adsorption force to firmly adsorb the cloth on the operation table 2 to prevent it from moving or wrinkling. When the cloth stacking is completed, the cloth blowing mode is turned on. The pushing driving member 333 drives the pushing rod 332 to move, driving the switching cylinder 331 to slide to the position where the cloth blowing port is docked with the cloth blowing channel 32. The positive pressure air flow generated by the pump assembly 1 flows through the shunt pipe 3, the cloth blowing channel 32, the air chamber 24 and the air hole 221 in sequence, forming a driving force to make the cloth away from the operation plate 22, reducing the friction between the cloth and the operation plate 22, improving the smoothness of cloth movement, and further reducing the possibility of cloth damage.

[0036] Further, referring to Figure 1 and Figure 3 , in order to reduce the possibility of the cloth shifting or wrinkling during the cloth sucking process, clamping assemblies 4 are arranged at both ends of the operation table 2, and the two clamping assemblies 4 clamp both ends of the cloth respectively.

[0037] The operation table 2 further includes bending plates 23, first elastic members 5 and limiting plates 51. The bending plates 23 are symmetrically arranged at both ends of the operation plate 22. One end of the first elastic member 5 is fixedly connected to the bottom wall of the bending plate 23, and the end of the first elastic member 5 away from the bending plate 23 is fixedly connected to the limiting plate 51. The bending plates 23 are bent on the operation plate 22 through the clamping assemblies 4, so that while clamping the cloth, the cloth is pulled, further reducing the stacking quality of the cloth.

[0038] Specifically, the bending plate 23 includes an inclined portion 231 and a bending portion 232. The thickness of the inclined portion 231 is greater than that of the bending portion 232. The inclined portion 231 is fixedly connected to the bending portion 232. One end of the bending portion 232 away from the inclined portion 231 is fixedly connected to the operation plate 22. The first elastic member 5 is fixedly connected to the inclined portion 231. In this embodiment, the bending portion 232 can be made of stainless steel, and the first elastic member 5 is a hinge with a torsion spring.

[0039] The clamping assembly 4 includes a clamping member 41, a second elastic member, a sliding column 42, a rotating member 43, and a rotation driving member 44. The clamping member 41 is in a C shape. The clamping member 41 is hinged to one side of the inclined portion 231. The second elastic member is used to clamp the clamping member 41 to the top wall of the inclined portion 231. In this embodiment, the second elastic member is a torsion spring. One end of the second elastic member is fixedly connected to the inclined portion 231, and the end of the second elastic member away from the inclined portion 231 is fixedly connected to the clamping member 41. The elastic force clamping direction of the second elastic member faces the top wall of the bending portion 232. One side of the clamping member 41 away from the bending portion 232 is fixedly connected to the sliding column 42, and the sliding column 42 is located at the end of the clamping member 41 away from the hinge. The rotating member 43 is rotatably connected to the frame 21. A sliding groove 431 is formed through the side of the rotating member 43 close to the frame 21. The sliding column 42 is inserted into the sliding groove 431. The length direction of the sliding groove 431 is parallel to the length direction of the rotating member 43. The rotating member 43 pushes the sliding column 42 to slide through the rotation driving member 44. The rotation driving member 44 is fixedly connected to the frame 21, and the output end of the rotation driving member 44 is fixedly connected to the rotating member 43. In this example, the rotation driving member 44 is a driving motor.

[0040] The clamping member 41 includes a hinge portion 411, a clamping portion 412, and a support portion 413. The hinge portion 411 is hinged to the inclined portion 231. The second elastic member is connected to the hinge portion 411. The hinge portions 411 are symmetrically arranged at both ends in the length direction of the bending portion 232. The hinge portion 411 is fixedly connected to the clamping portion 412. The hinge portions 411 are symmetrically arranged at both ends of the clamping portion 412. The support portion 413 is arranged between the two hinge portions 411. The support portion 413 is connected to the hinge portion 411. When the clamping portion 412 clamps the fabric, the top wall of the support portion 413 and the top wall of the operation plate 22 are on the same horizontal plane. In this example, the support portion 413 is arc-shaped, so that the top wall of the support portion 413 is tangent to the top wall of the operation plate 22.

[0041] To facilitate the feeding of the fabric, when the fabric is being laid, the top wall of the clamping portion 412 and the top wall of the operation plate 22 are on the same horizontal plane. The rotating end of the rotating member 43 is between the hinge joint of the sliding column 42 and the hinge portion 411 in this state, and is located at the bottom of the hinge joint of the hinge portion 411, which is convenient for pushing the sliding column 42.

[0042] When clamping the fabric, place the fabric in the area of the air holes 221. The fabric is laid on the inclined part 231. The rotation driving part 44 drives the rotating part 43 to rotate towards one end close to the inclined part 231. The rotation of the rotating part 43 drives the sliding column 42 to move until the clamping part 412 fits against the fabric located on the inclined part 231. Under the elastic force of the second elastic part, the clamping part 412 and the inclined part 231 clamp the fabric. Continuously rotate the rotating part 43, and the rotating part 43 drives the sliding column 42 to continue to move downward, thereby pushing the inclined part 231, causing the bending part 232 to bend, thereby pulling the fabric and making the fabric in a taut and unfolded state, reducing the possibility of wrinkling caused by later stacking of the fabric, and further improving the quality of fabric stacking.

[0043] Furthermore, there is a gap between the end of the support part 413 away from the clamping part 412 and the inclined part 231, enabling the clamping assembly 4 to better adapt to the thickness change of the fabric when clamping the fabric, reducing the possibility of uneven clamping force caused by structural interference, improving the versatility and stability of the clamping assembly 4, ensuring that fabrics of different thicknesses can be firmly clamped, and thus further enhancing the flatness and cutting accuracy of fabric laying.

[0044] The implementation principle of an automatic fabric laying machine with switchable fabric suction and blowing in the embodiment of this application is as follows: When the fabric is laid on the operation board 22, start the rotation driving part 44. The rotation driving part 44 drives the rotating part 43 to rotate, driving the sliding column 42 to push until the sliding column 42 abuts against the fabric. Continuously rotate the rotating part 43. The rotating part 43 drives the inclined bar to rotate through the sliding column 42, thereby tightening the fabric. Start the fabric suction mode. The pushing driving part 333 drives the pushing rod 332 to move, driving the switching cylinder 331 to slide to the position where the fabric suction port is docked with the fabric suction channel 31. The negative pressure air flow generated by the pump assembly 1 passes through the shunt pipeline 3, the fabric suction channel 31, the air storage box 24 and the air holes 221 to form an adsorption force, firmly adsorbing the fabric on the operation table 2 to prevent it from moving or wrinkling; after the fabric is clamped and the air suction mode is started, then stack the fabric. When the fabric stacking is completed, start the rotation driving part 44. The rotation driving part 44 drives the rotating part 43 to rotate towards the end away from the inclined part 231. The rotating part 43 disengages from the top wall of the inclined part 231 through the sliding column 42. Under the action of the first elastic part 5, the top of the inclined part 231 and the top wall of the operation board 22 are located on the same plane. Start the fabric blowing mode. The pushing driving part 333 drives the pushing rod 332 to move, driving the switching cylinder 331 to slide to the position where the fabric blowing port is docked with the fabric blowing channel 32. The air flow reversely sprays out from the air holes 221, pushing the fabric to move, reducing the friction of the fabric during movement. Thus, the fabric can be firmly adsorbed or easily blown during the laying process, effectively reducing the movement or wrinkling of the fabric, and improving the quality of fabric stacking and operation efficiency.

[0045] The above are all preferred embodiments of the present application. This embodiment is only an explanation of the present application and does not limit the protection scope of the present application in sequence. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
