Description

Technical Field

[0001] The present invention relates to the technical field of spreading machines, and in particular, to an automatic multi-layer spreading machine. Background Art

[0002] A spreading machine is a machine for making cloth that emerged in the early 1990s. Since flexible materials are mostly produced and transported in rolls, when they reach the user's factory, an important process is to convert the rolled materials into a multi-layer planar state for convenient cutting and use. Thus, automated production equipment such as automatic spreading machines and automatic laying machines came into being.

[0003] The existing spreading machines have the following deficiencies in the specific use process: 1. They can only perform single-layer spreading, with low spreading efficiency; 2. The height of the spreading machine is fixed, with certain limitations in use; 3. The tightness of the cloth in the spreading machine cannot be adjusted.

[0004] Therefore, a new type of automatic multi-layer spreading machine can be adopted to solve the deficiencies of the prior art. Summary of the Invention

A plurality of first rollers 8 are rotatably installed on each of the two first support plates 6. A plurality of rotating shaft grooves are formed in the roller frame 9. A rotating shaft 14 is rotatably installed in each rotating shaft groove. A fabric roller 12 is fixedly installed on each rotating shaft 14. Fabric 13 is wound on each fabric roller 12. A plurality of first clamping rollers 18 are rotatably installed on each of the two first support plates 6. A plurality of sliding plates 20 are slidably installed on the two first support plates 6. A second clamping roller 19 that cooperates with the corresponding first clamping roller 18 is rotatably installed on each sliding plate 20. A plurality of sliders 27 are slidably installed on the second support plate 7. A fourth roller 28 is rotatably installed on each slider 27. A plurality of fixed sleeves 30 are fixedly installed on the second support plate 7. A nut 31 is rotatably installed on each fixed sleeve 30. A screw 29 is threadedly rotated on each nut 31. Each screw 29 is fixedly connected to the corresponding slider 27. An installation plate 34 and a support frame 37 are fixedly installed on the base 1. A toothed disc 36 is rotatably installed on each of the installation plate 34 and the support frame 37. A motor 35 is fixedly installed on the installation plate 34. The driving end of the motor 35 is fixedly connected to the toothed disc 36 on the installation plate 34. A chain 38 is sleeved between the two toothed discs 6. A connecting block 39 is fixedly installed on the chain 38. A top rod 40 is rotatably installed on the connecting block 39. A top plate 41 is fixedly installed on the top rod 40. The top plate 41 is slidably connected to the support plate 5; A plurality of baffles 15 that cooperate with the rotating shafts 14 are slidably installed on the roller frame 9. A fixing plate 16 is fixedly installed on each baffle 15. A first spring 17 is fixedly installed between each fixing plate 16 and the roller frame 9. The purpose of this setting is to limit the rotating shaft 14 to prevent the rotating shaft 14 from separating from the rotating shaft groove.

[0028] A plurality of ball grooves are formed in each sliding plate 20. A ball 21 is rotatably installed in each ball groove. A sliding groove 22 that abuts against all the balls 21 is formed in the first support plate 6. Two electric push rods 25 are fixedly installed in the sliding groove 22. A resisting plate 23 is fixedly installed on the two electric push rods 25. Each resisting plate 23 is slidably connected to the sliding groove 22. A plurality of second springs 24 are fixedly installed between each resisting plate 23 and the corresponding sliding plate 20. The purpose of this setting is to adjust the clamping force of the first clamping roller 18 and the second clamping roller 19 on the fabric 13, so as to improve the flatness of the fabric 13.

[0029] Multiple slots are provided on the second support plate 7, and a rack 33 is slidably installed in each slot. A gear 32 that cooperates with the corresponding two racks 33 is fixedly installed on each nut 31. This setting is for facilitating the rotation of the nut 31.

[0030] Two support baffles are fixedly installed on the roller frame 9, and a second roller 10 and multiple third rollers 11 are rotatably installed on each of the two support baffles. This setting is for supporting the fabric 13 to prevent the fabric 13 from collapsing.

[0031] A limit block is fixedly installed on the top plate 41, and a limit groove that cooperates with the limit block is provided on the support plate 5. This setting is for facilitating the sliding of the top plate 41 on the support plate 5.

[0032] The lengths of the first roller 8, the second roller 10, the third roller 11, the first pinch roller 18, the second pinch roller 19, and the fourth roller 28 are equal to the width of the fabric 13. This setting is for ensuring that the fabric 13 is completely pressed within the first roller 8, the second roller 10, the third roller 11, the first pinch roller 18, the second pinch roller 19, and the fourth roller 28, and avoiding the appearance of excess parts, resulting in uneven fabric pulling.

[0033] First, thread the fabric 13 as Figure 1 shown. The electric push rod 25 can drive the abutting plate 23 to move, thereby changing the elastic force of the second spring 24, so as to change the abutting pressure between the first pinch roller 18 and the second pinch roller 19, and thus improve the flatness of the fabric 13;

[0034] Insert the rack 33 into the slot. Since the rack 33 meshes with the gear 32, the movement of the rack 33 will drive the gear 32 to rotate, thereby driving the nut 31 to rotate. The rotation of the nut 31 will drive the screw rod 29 to move, so as to adjust the height of the slider 27 and the fourth roller 28, and thus adjust the tightness of the fabric 13.

[0035] Lifting: Turn on the motor 35. The motor 35 drives the toothed disc 36 to rotate, causing the ejector rod 40 to move together with the chain 38. Due to the inclined arrangement of the chain 38, the movement of the chain 38 will drive the ejector rod 40 and the top plate 41 to move up, down, left, and right, so as to achieve the purpose of height adjustment.

[0036] 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 should be covered within the protection scope of the present invention.
