Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, in particular to a clamping device for producing flame-retardant spun woolen fabrics. Background Art

[0002] After the production of flame-retardant spun plush fabrics is completed, the impurities on the surface of the plush fabrics need to be cleaned. Only after the cleaning is completed can the subsequent pattern printing or packaging and sales be carried out. After searching, the prior art (application number: CN202320660049.4) records "a clamping device for automatic dust removal equipment for plush fabrics, installed above the frame, used to convey and clamp the material into the dust removal processing part for spray dust removal. The clamping device includes a feed conveying mechanism, a downward pressure shaping mechanism, and a clamping mechanism. The downward pressure shaping mechanism is located at the conveying end of the feed conveying mechanism, and the feed port of the downward pressure shaping mechanism is arranged at the same horizontal plane as the feed conveying mechanism. The downward pressure shaping mechanism is arranged along the Y direction and opens and closes up and down along the Z axis. The clamping end of the clamping mechanism clamps the material through the tooth gap of the downward pressure shaping mechanism, and transfers the clamped material to the dust removal hood of the dust removal processing part along the X direction. This application has the advantages of high degree of automation, simple structure of the entire equipment, easy implementation, and can effectively reduce its cost."

[0003] However, although the clamping device for automatic dust removal equipment of plush fabrics in the prior art can achieve the effect of automatic clamping and movement, it still has some shortcomings: the existing plush fabric clamping device clamps the fabric in a superimposed state when in use, which makes it impossible to turn it over during the dust removal process, thereby resulting in poor dust removal effect in the dust removal hood. At the same time, the clamping device requires the use of multiple auxiliary devices or equipment to achieve the dust removal effect. For simple dust removal operations, it not only occupies a relatively large use space, but also increases the use cost. Utility Model Content

[0030] Reference Figures 1 to 6 As shown, the utility model provides a clamping device for the production of flame-retardant spun woolen fabrics, comprising: a device body 1, the device body 1 comprises a moving frame 2, and a blowing pipe 21 is provided on the inner side of the moving frame 2, and a blowing nozzle 22 is connected to the lower end of the blowing pipe 21, a clamping roller 4 is provided on the lower side of the blowing nozzle 22, and the clamping roller 4 is rotatably connected to the inner side of the moving frame 2, and a driving component 3 is connected to the outer side of the clamping roller 4, and the driving component 3 is installed on the outer side of the moving frame 2, a guide plate 41 is connected to the outer side of the clamping roller 4, and a ventilation hole 411 is opened inside the guide plate 41, and an articulated seat 42 is provided on the outer wall of the clamping roller 4, a rotating plate 43 is hinged on the inner side of the articulated seat 42, and a pressing block 44 is connected to the outer end of the rotating plate 43, and a rotating cylinder 45 is installed on the outer wall of the articulated seat 42.

[0031] In this embodiment, the moving frame 2, the driving assembly 3 and the clamping roller 4 included in the device body 1 constitute the overall structure of the clamping device for producing flame-retardant spun woolen fabric involved in this application.

[0032] As a preferred embodiment, by opening rectangular strip-shaped ventilation holes 411 inside the guide plate 41, when the fabric is located at the lower side of the clamping roller 4, the air flow ejected from the blowing nozzle 22 can pass through the guide plate 41 to reach the fabric surface.

[0033] refer to Figure 2 The movable frame 2 is set as an N-shaped frame structure, and the outer side of the movable frame 2 is slidably connected with a linear driving guide rail 5, both ends of the blowing pipe 21 are set as blocked ends, and the blowing pipe 21 is connected to an air pump through a hose, and the blowing nozzles 22 are equidistantly arranged on the lower side wall of the blowing pipe 21.

[0034] In this embodiment, the horizontal length of the air blowing pipe 21 is greater than the clamping roller 4, and the air flow width of the air blowing nozzle 22 is greater than the width of the fabric.

[0035] refer to Figure 1 and Figure 2 The driving assembly 3 includes a motor 31 installed inside the mobile frame 2, and the outer end of the output shaft of the motor 31 is connected to a first pulley 32. The driving assembly 3 also includes a main gear 35 rotatably connected to the outside of the mobile frame 2, and a slave gear 36 is meshed on the lower side of the main gear 35. A second pulley 34 is coaxially connected to the outside of the main gear 35, and a transmission belt 33 is connected between the second pulley 34 and the first pulley 32. A driving shaft 37 is connected to the inside of the slave gear 36, and the driving shaft 37 is axially inserted and fixed inside the clamping roller 4 at the same time, and the driving shaft 37 is rotatably connected to the inner wall of the mobile frame 2 at one end away from the slave gear 36.

[0036] As a preferred embodiment, the drive assembly 3 is provided to facilitate the flipping of the clamping roller 4 and thus the turning over of the fabric.

[0037] It should be noted that the distance the fabric passes over the clamping roller 4 is determined by the photoelectric sensor arranged on the inner side of the movable frame 2 and the time relay included in the external controller, so that the conveyance of the fabric is stopped when the symmetry line of the fabric is located on the upper side of the clamping roller 4, and the rotating cylinder 45 is started for clamping.

[0038] Specifically, when the fabric head enters the surface of the clamping roller 4, the photoelectric sensor is sensed, and the red relay starts timing. At the same time, the controller calculates the fabric conveying time and the speed of the conveyor belt to obtain the passing displacement (i.e., length) on the clamping roller 4, and then obtains half of the length limit value based on the overall length of a section of fabric. When the limit value is reached, the conveying can be stopped and the rotating cylinder 45 can be started.

[0039] refer to Figure 1 , Figure 3 and Figure 4 Conveyor belts of different heights are provided on both sides of the clamping roller 4, and an arc chamfer is provided at the outer end of the guide plate 41, and the arc chamfer matches the curvature of the transmission roller at one end of the conveyor belt.

[0040] As a preferred embodiment, a guide plate 41 is provided and an arc chamfer is formed at the end thereof, so that a seamless connection is made at one end of the conveyor belt, thereby guiding the fabric to the clamping roller 4 .

[0041] It should be noted that a V-shaped outer support plate can be provided on the outer wall of the clamping roller 4 and on the side opposite to the pressure block 44, so that the fabric can be supported when it is hung upside down on the back side, thereby reducing the wind blocking effect of the clamping roller 4, or the blowing nozzle 22 can be set to two sets of inclined states to avoid the position of the clamping roller 4.

[0042] When in use, the fabric transported by the conveyor belt enters the upper part of the clamping roller through the guide of the guide plate, and then the front end of the fabric bends downward and hangs down. When the middle part of the fabric is on the clamping roller, the conveying is stopped and the rotating cylinder is started at the same time to drive the rotating shaft to drive the rotating plate to flip, thereby driving the pressing block to rotate, so that the two side edges of the fabric are clamped. At this time, the blowing pipe and the blowing nozzle keep working synchronously, so that the upper part of the fabric is blown to remove dust, and then the linear drive guide rail is started to move one end of the moving frame away, and then the motor is started to drive the drive shaft to rotate through the first pulley, the transmission belt, the second pulley, the main gear and the slave gear, thereby driving the clamping roller to rotate, so that the fabric is rotated to achieve the flipping effect, and then the turned side of the fabric is blown to remove dust, realizing double-sided dust removal operation and enhancing the dust removal effect.
