Description

Technical Field

[0001] This utility model relates to the field of fabric spreading machines, specifically a fabric roller support device for fabric spreading machines. Background Technology

[0002] A fabric spreading machine is a device that flattens and lays out layers of rolled fabric. It mainly includes a spreading bed, a feeding mechanism, a pressing mechanism, and a spreading mechanism. After the feeding mechanism conveys the fabric to the spreading bed, the spreading mechanism clamps and moves the fabric to the spreading bed. After moving a set distance, the spread fabric is cut so that it can be laid out on the spreading bed. This process is repeated to lay out layers of the flattened fabric.

[0003] For example, our company's earlier patent application, authorized by publication number CN220299899U, discloses a fabric spreading machine edge-aligning mechanism, including a base and a fabric hopper. The fabric hopper is movably mounted on top of the base and can move along the left and right direction of the base. The fabric hopper is used to load the fabric roll to be unrolled. The base is generally a rectangular frame, and two track beams are provided on the inner side of the base. A slide rail is fixedly installed on the top of the track beams, and a slider is slidably connected on the slide rail. The fabric hopper includes a bottom frame and side supports located on the left and right sides of the bottom frame. The side supports are generally inverted arch shape, and four support rollers are provided between the two side supports. The support rollers are rotatably connected to the support shaft through bearings, and the support shaft is fixedly installed on the inner side of the side supports by fixing screws.

[0004] The aforementioned patent allows for adjustment of the fabric roll position when the fabric shifts, ensuring alignment on both sides during subsequent conveying; this reduces subsequent adjustments to the fabric position, thereby reducing fabric pulling. However, the disadvantage of the aforementioned patent is that, since the fabric rolls are all wound around a single fabric roll roller, the lack of a support structure for the fabric roll roller during unwinding makes it easy for the fabric roll to deflect during unwinding, resulting in deflection of the unwound fabric.

[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

The support shaft 204 is fixedly installed on the inner side of the side supports 201 by fixing screws 205.

[0025] When in use, the fabric roll is placed on the fabric hopper 2, and the support roller 202 can rotate, so that the fabric roll can rotate smoothly;

[0026] The supporting shaft 204 between the side supports 201 not only serves as the rotating shaft of the supporting roller 202, but also as the connection between the two side supports 201.

[0027] In this solution, the base 1 is a rectangular frame, and support feet 101 are fixedly installed at the four corners of the base 1. Two track beams 102 are provided on the inner side of the base 1. A slide rail 103 is fixedly installed on the top of the track beams 102, and a slider 104 is slidably connected on the slide rail 103.

[0028] It is worth noting that this solution also includes a cloth roller support structure 4, which is symmetrically arranged in two sets. The cloth roller support structure 4 includes a support frame 410 and a slide table 420. The bottom of the slide table 420 is slidably mounted on the slide rail 103 via a slider 104.

[0029] The support frame 410 includes a sub-rod 411 and a main rod 412. The main rod 412 is sleeved on the sub-rod 411, and the cross sections of both the sub-rod 411 and the main rod 412 are rectangular. A compression spring 413 is also provided between the sub-rod 411 and the main rod 412. A U-shaped support groove 414 is provided at the top of the main rod 412.

[0030] In this solution, a drive device 3 is also included, which includes a stepper motor 301 and a ball screw mechanism 310. The stepper motor 301 drives the cloth bucket 2 to move through the ball screw mechanism 310.

[0031] The stepper motor 301 is fixedly installed at the bottom of the motor mounting plate 302, and the top of the motor mounting plate 302 is fixedly installed on the right side of the base 1. The output shaft of the stepper motor 301 is driven to connect to the ball screw mechanism 310 through the gear transmission structure 303.

[0032] The ball screw mechanism 310 includes a lead screw 311 and a lead screw nut 312. The two ends and the middle of the lead screw 311 are rotatably connected to the bearing seat 313 through bearings. The bearing seat 313 is fixedly installed at the bottom of the base 1. The other end of the lead screw 311 extends out of the right side of the base 1 and is fixedly connected to the gear of the gear transmission structure 303.

[0033] The lead screw nut 312 is fixedly installed in the nut seat 314, and the nut seat 314 is fixedly installed at the bottom of the slide table 420; in this scheme, the lead screw 311 includes a forward rotation section 316 and a reverse rotation section 315, and the rotation directions of the lead screw in the forward rotation section 316 and the reverse rotation section 315 are opposite; the two sets of cloth roller support structures 4 are located above the forward rotation section 316 and the reverse rotation section 315;

[0034] The stepper motor 301 drives the lead screw 311 to rotate through the gear transmission structure 303. The lead screw 311 drives the two sets of slide tables 420 to approach or move away from each other through the lead screw nut 312, thereby adapting to the cloth rollers of different lengths of cloth rolls.

[0035] When this utility model is in use, the fabric roll is placed on the fabric hopper 2; the fabric roller of the fabric roll is placed in the U-shaped support groove 414 at the top of the mother rod 412; at this time, the fabric roll is in contact with the support roller 202. As the fabric roll is unwound, the height of the fabric roller of the fabric roll decreases accordingly. At this time, since a compression spring 413 is also provided between the sub-rod 411 and the mother rod 412, the height of the mother rod 412 also decreases accordingly; when unwound further, there is very little fabric left on the fabric roll, and at this time the fabric roll cannot contact the support roller 202; the mother rod 412 can also serve as a fabric roller to support the fabric roll.
