DETAILED DESCRIPTION

[0018] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0019] Embodiment: A wire drawing prevention device, such as Figure 1-Figure 3 As shown, it comprises: a base 1, a fixed block 2 is fixedly installed on one side of the top of the base 1, a mounting groove 3 is opened on the top of the fixed block 2, a forward and reverse screw 4 is rotatably installed inside the mounting groove 3 through a bearing, one end of the forward and reverse screw 4 passes through the fixed block 2 and a first motor 5 fixedly installed on the base 1 is connected to the keyway, a moving block 6 is meshedly connected to the outside of the forward and reverse screw 4, and the number of the moving blocks 6 is two, the moving block 6 is slidably installed with the fixed block 2 along the length direction of the forward and reverse screw 4 through the mounting groove 3, a fixed plate 7 is fixedly installed on one side of the outside of the moving block 6, and the number of the fixed plates 7 is two, and the tops of the two fixed plates 7 are both rotatably installed with a limiting roller 8 to move the cloth When spreading the cloth, due to the different widths of the cloth, an adjustment device is required to limit the cloth. At this time, the first motor 5 works to drive the forward and reverse screws 4 to rotate, and the rotation of the forward and reverse screws 4 drives the two moving blocks 6 to slide along the length direction of the forward and reverse screws 4, thereby changing the distance between the two moving blocks 6, and effectively adjusting according to the width of the cloth. The two sides of the cloth are in contact with the four limiting rollers 8, thereby playing a limiting role. At the same time, the limiting rollers 8 can rotate. During the movement of the cloth, the limiting rollers 8 rotate due to the friction force, thereby reducing the friction between the cloth and the limiting rollers 8, effectively avoiding the drawing of the two ends of the cloth due to friction, and greatly improving the practicality.

[0020] A first clamping roller 9 is rotatably installed on the outer side of the moving block 6 and located between the two fixed plates 7. A support rod 10 is fixedly installed on the top of the moving block 6, and the number of the support rods 10 is two. A top plate 11 is fixedly installed between the tops of the two support rods 10. A screw rod 12 is rotatably installed on the top of the moving block 6 and located between the two support rods 10 through a bearing. The top end of the screw rod 12 passes through the top plate 11 and a knob 13 is connected to the keyway. A lifting block 14 is meshedly connected to the outside of the screw rod 12. The lifting block 14 is slidably installed along the length direction of the screw rod 12 and the support rod 10. A second clamping roller 15 is rotatably installed on one side of the outer side of the lowering block 14 through a bearing. The cloth passes between the first clamping roller 9 and the second clamping roller 15. The screw rod 12 is effectively driven to rotate by turning the knob 13. The rotation of the screw rod 12 drives the lifting block 14 to slide along the length direction of the support rod 10, thereby changing the height of the second clamping roller 15, so that the second clamping roller 15 and the first clamping roller 9 are both in contact with the cloth, effectively limiting the two ends of the cloth, thereby improving the stability of the cloth spreading. At the same time, this structure is easy to adjust according to cloth of different thicknesses, thereby improving applicability.

[0021] A mounting plate 16 is fixedly installed on the other side of the top of the base 1, and there are two mounting plates 16. A material roller 17 is rotatably installed between the two mounting plates 16 through a bearing. One end of the material roller 17 passes through one of the mounting plates 16 and extends to the outside. A keyway at one end of the material roller 17 is connected to a second motor 18 fixedly installed on one of the mounting plates 16. The cloth to be spread is placed on the outside of the material roller 17, and the rotation of the second motor 18 effectively drives the material roller 17 to rotate, so that it is convenient to retract and release according to needs.

[0022] The working principle of the anti-wire drawing spreading device provided by the utility model is as follows:

[0023] The first step: place the cloth that needs to be spread on the outside of the material roller 17, and effectively drive the material roller 17 to rotate through the rotation of the second motor 18, so as to facilitate the collection and release processing according to the needs. When the cloth is spread, due to the different widths of the cloth, it is necessary to adjust the device to limit the cloth. At this time, the first motor 5 works to drive the forward and reverse screws 4 to rotate, and the rotation of the forward and reverse screws 4 drives the two moving blocks 6 to slide along the length direction of the forward and reverse screws 4, thereby changing the distance between the two moving blocks 6, and effectively adjusting according to the width of the cloth. The two sides of the cloth are in contact with the four limiting rollers 8, thereby playing a limiting role. At the same time, the limiting rollers 8 can rotate. During the movement of the cloth, the limiting rollers 8 rotate due to the action of friction, thereby reducing the friction between the cloth and the limiting rollers 8, effectively avoiding the drawing of the two ends of the cloth due to friction, and greatly improving the practicality.

[0024] Step 2: The cloth passes between the first clamping roller 9 and the second clamping roller 15. The screw rod 12 is effectively driven to rotate by turning the knob 13. The rotation of the screw rod 12 drives the lifting block 14 to slide along the length direction of the support rod 10, thereby changing the height of the second clamping roller 15, so that the second clamping roller 15 and the first clamping roller 9 are both in contact with the cloth, effectively limiting the two ends of the cloth, thereby improving the stability of the cloth spreading. At the same time, this structure is easy to adjust according to cloth of different thicknesses, thereby improving applicability.

[0025] Finally, it should be pointed out that the above embodiments are only representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model should be considered to belong to the protection scope of the present utility model.
