Description

Technical Field

[0001] The utility model belongs to the technical field of fabric printing, and particularly relates to an anti-static device for a printing machine. Background Technique

[0002] Fabric printing is a process of transferring patterns, designs or colors onto fabrics (such as cotton, silk, linen, chemical fiber, synthetic fiber, etc.) through specific processes, adding aesthetic and decorative effects, and is widely used in the fields of clothing, home textiles, decoration, artworks, etc.

[0003] The existing anti-static device for a printing machine guides the fabric before printing on the printing machine, so that the fabric contacts the static eliminator roller during the conveying process, and the static eliminator roller eliminates the static electricity on the fabric. However, in the actual use process, due to the certain elasticity of the fabric, the fabric cannot fully contact the static eliminator roller when eliminating static electricity, which may lead to short contact time and incomplete contact between the contact position and the static eliminator roller when eliminating static electricity, affecting the static electricity elimination of the fabric and the anti-static effect. Content of the Utility Model

[0004] In view of this, aiming at the deficiencies of the existing technology, the utility model provides an anti-static device for a printing machine, which realizes the elimination of static electricity on the fabric through the cooperation of a tensioning roller and a static eliminator roller during the conveying process, and then the dust on the fabric surface is sucked by a vacuum cleaner, which can effectively ensure the printing effect of the printing machine.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is: an anti-static device for a printing machine, including a frame, the lower surface of the frame is provided with a plurality of uniformly distributed supporting feet, the right side inside the frame is rotatably provided with a first conveying roller, the left side inside the frame is rotatably provided with a second conveying roller, the rear side of the frame is provided with two symmetrically distributed motors I on the left and right, the output shaft of the left motor I is fixed to the second conveying roller through a coupling, the output shaft of the right motor I is fixed to the first conveying roller through a coupling, the inside of the frame is rotatably provided with two symmetrically distributed guiding rollers on the left and right, the middle parts of the front and rear inner walls of the frame are both provided with a first U-shaped mounting seat, a guide rail is arranged inside each first U-shaped mounting seat, a movable frame is slidably arranged between the outer arc surfaces of the two guide rails, two symmetrically distributed static eliminator rollers are rotatably arranged on the lower side inside the movable frame, and the frame is also provided with an electronic control module for driving the static eliminator rollers to move; a vacuum cleaner is arranged on the right side inside the frame.

[0006] As a further improvement of the utility model, the electronic control module includes U-shaped mounting seats II arranged on the lower sides of the inner walls on the front and rear sides of the frame. Slide rails are arranged inside both U-shaped mounting seats II. Two symmetrically distributed sliders are slidably arranged on the outer sides of both slide rails. Connecting rods are rotatably arranged at the tops of the four sliders. The ends of the connecting rods far from the sliders are rotatably connected to the movable frame. Tightening rollers are rotatably arranged between two adjacent sliders, one in front and the other behind. An electronic control unit for driving the sliders to move is also arranged on the frame; the electronic control unit includes a bidirectional lead screw rotatably arranged inside both U-shaped mounting seats II. Thread grooves opened inside the sliders are respectively in threaded connection with the adjacent bidirectional lead screws. An electronic control assembly for driving the bidirectional lead screw to rotate is also arranged on the frame.

[0007] As a further improvement of the utility model, the electronic control assembly includes motors II arranged on the inner walls on the front and rear sides of the frame. The output shafts of the motors II are respectively fixed to the adjacent bidirectional lead screws through couplings; a control panel is arranged on the front side of the frame. Motor I, the vacuum cleaner and the motors II are all electrically connected to the control panel.

[0008] As a further improvement of the utility model, ceramic coatings are applied to the outer sides of conveying roller I, conveying roller II and the guiding roller.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] Firstly, the motors II on the left and right sides are controlled by the control panel to operate synchronously, so that the output shafts of the motors II respectively drive the adjacent bidirectional lead screws to rotate, so that the sliders on the left and right sides drive the tightening rollers on the left and right sides to move in a direction away from each other, quickly tighten the fabric, and adjust the tension of the fabric to a certain extent.

[0011] Secondly, during the movement of the sliders on the left and right sides, the sliders on the left and right sides drive the movable frame to slide between the two guide rails through the connecting rods. After the fabric is tightened by the tightening rollers, the static elimination roller presses down and contacts, which can effectively increase the static elimination effect on the fabric and avoid the decline of the printing effect caused by electrostatic adsorption of dust during the printing process.

[0012] Thirdly, the control panel controls the operation of motor I and the vacuum cleaner. The conveying rollers I and II are driven to rotate by the motors I on the left and right sides to realize the conveying of the fabric. During the conveying process, the static electricity of the fabric is eliminated by the cooperation of the tightening rollers and the static elimination rollers, and then the dust on the surface of the fabric is sucked by the vacuum cleaner, which can effectively ensure the printing effect of the printing machine.

[0013] Fourthly, the ceramic coatings applied to the outer sides of conveying roller I, conveying roller II and the guiding roller can reduce the friction with the fabric and avoid generating static electricity at the same time, which can further improve the anti-static effect during the printing process of the fabric.

In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details.

[0021] Such as Figure 1 , 3, as shown in Figures 4, it includes a frame 101. A plurality of uniformly distributed feet 102 are provided on the lower surface of the frame 101. A first conveying roller 103 is rotatably provided on the right side inside the frame 101. A second conveying roller 107 is rotatably provided on the left side inside the frame 101. Two motors 104 symmetrically distributed left and right are provided at the rear side of the frame 101. The output shaft of the left motor 104 is fixedly connected to the second conveying roller 107 through a coupling. The output shaft of the right motor 104 is fixedly connected to the first conveying roller 103 through a coupling. Two guide rollers 105 symmetrically distributed left and right are rotatably provided inside the frame 101. U-shaped mounting seats 201 are provided in the middle of the front and rear inner walls of the frame 101. Guide rails 202 are provided inside the U-shaped mounting seats 201. A movable frame 203 is slidably provided between the outer arc surfaces of the two guide rails 202. Two electrostatic elimination rollers 204 symmetrically distributed left and right are rotatably provided on the lower side inside the movable frame 203. An electronic control module for driving the movement of the electrostatic elimination rollers 204 is also provided on the frame 101.

[0022] As Figure 1 , 3 , as shown in Figures 4, a dust collector 106 is provided on the right side inside the frame 101.

[0023] As Figure 2 , 3 , as shown in Figures 4, the electronic control module includes U-shaped mounting seats 205 provided on the lower sides of the front and rear inner walls of the frame 101. Guide rails 206 are provided inside the two U-shaped mounting seats 205. Two sliders 207 symmetrically distributed left and right are slidably provided on the outer sides of the two guide rails 206. Connecting rods 209 are rotatably provided at the tops of the four sliders 207. The ends of the connecting rods 209 away from the sliders 207 are rotatably connected to the movable frame 203. Tightening rollers 208 are rotatably provided between two adjacent sliders 207 front and rear. An electronic control unit for driving the movement of the sliders 207 is also provided on the frame 101; the electronic control unit includes a bidirectional lead screw 210 rotatably provided inside the two U-shaped mounting seats 205. Thread grooves opened inside the sliders 207 are respectively threadedly connected to the adjacent bidirectional lead screws 210. An electronic control component for driving the rotation of the bidirectional lead screws 210 is also provided on the frame 101; the electronic control component includes motors 211 provided on the front and rear inner walls of the frame 101. The output shafts of the motors 211 are fixedly connected to the adjacent bidirectional lead screws 210 through couplings.

[0024] As Figure 1 As shown in the figure, a control panel 301 is provided on the front side of the frame 101. The motors 104, the dust collector 106 and the motors 211 are all electrically connected to the control panel 301.

[0025] When printing on fabric is required, the operator passes the fabric around the second conveying roller 107, then downwards through the left guiding roller 105, upwards after passing around the lower sides of the two tensioning rollers 208, and is conveyed towards the printing machine by the first conveying roller 103 after passing through the right guiding roller 105; the control panel 301 regulates the synchronous operation of the motors two 211 on both the left and right sides, so that the output shafts of the motors two 211 drive the bidirectional lead screws 210 connected thereto to rotate respectively. Through the threaded relationship between the bidirectional lead screws 210 and the sliders 207, the sliders 207 on both the left and right sides are driven to move in a separating direction, and thus the sliders 207 on both the left and right sides drive the tensioning rollers 208 on both the left and right sides to move in a separating direction to quickly tension the fabric. During the movement of the sliders 207 on both the left and right sides, rotations occur between the sliders 207 and the connecting rods 209, and between the connecting rods 209 and the movable frames 203. Thus, the sliders 207 on both the left and right sides drive the movable frames 203 to slide between the two guide rails 202 through the connecting rods 209, and then the guide rails 202 drive the two static eliminator rollers 204 on the lower side inside thereof to contact the fabric tensioned between the two tensioning rollers 208. After the fabric is tensioned by the tensioning rollers 208, the downward contact of the static eliminator rollers 204 can effectively increase the static elimination effect on the fabric and avoid the decline in the printing effect caused by static adsorption of dust during the printing process; the control panel 301 regulates the operation of the motor one 104 and the vacuum cleaner 106. The first conveying roller 103 and the second conveying roller 107 are driven to rotate by the motors one 104 on both the left and right sides to realize the conveyance of the fabric. During the conveyance process, the cooperation of the tensioning rollers 208 and the static eliminator rollers 204 realizes the elimination of static electricity on the fabric, and then the vacuum cleaner 106 sucks the dust on the surface of the fabric, which can effectively ensure the printing effect of the printing machine.

[0026] According to another embodiment of the present invention, as Figure 1 、 4 shown, ceramic coatings are applied on the outer sides of the first conveying roller 103, the second conveying roller 107, and the guiding roller 105. During the process of printing on the fabric, the ceramic coatings applied on the outer sides of the first conveying roller 103, the second conveying roller 107, and the guiding roller 105 can reduce the friction with the fabric and avoid generating static electricity at the same time, which can further improve the anti-static effect.
