Description

Technical Field

[0001] This utility model relates to the field of curtain fabric processing technology, specifically a double-sided linkage type curtain fabric precision positioning and cutting device. Background Technology

[0002] In today's home decoration market, curtains, as an important soft furnishing element, have received increasing attention for their quality and craftsmanship. Curtain production involves multiple stages, and fabric cutting is a crucial step, directly determining the dimensional accuracy, splicing effect, and final overall aesthetics of the curtains. Traditional curtain fabric cutting methods mostly rely on manual operation, with workers using experience and simple measuring tools. This method is not only inefficient but also difficult to guarantee cutting accuracy due to human factors. For example, workers are prone to fatigue and visual errors during long periods of repetitive operation, leading to inconsistent cutting sizes and affecting the quality stability of the curtains. With the advancement of industrialization, some semi-automatic or fully automatic cutting equipment has begun to be applied to the curtain manufacturing field. However, these existing devices have many limitations. On the one hand, during the fabric conveying process, due to the lack of effective positioning and anti-deviation measures, the fabric is easily affected by the vibration of the equipment itself, uneven friction of the conveying mechanism, and surrounding environmental factors, causing it to shift. Once this happens, the cut fabric will have problems such as inconsistent width and inaccurate length, greatly increasing the scrap rate and raising production costs. Utility Model Content

[0019] 1. By setting up a linkage anti-deviation mechanism, the offset sensor monitors the fabric deviation in real time. Once a deviation trend is detected, the fabric can be quickly and accurately adjusted to ensure that the fabric remains relatively flat and accurate in position during the cutting process.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 This utility model provides a technical solution: a double-sided linkage type curtain fabric precision positioning and cutting device.

[0030] Example 1

[0031] This embodiment discloses: a base 1, a mounting frame 2 fixedly mounted on the upper surface of the base 1, a cutting hydraulic rod 3 fixedly mounted on the upper surface of the mounting frame 2, a cutting blade 4 fixedly mounted on the lower end of the cutting hydraulic rod 3, a mounting plate 5 fixedly mounted on the outer surface of the mounting frame 2, a drive motor 6 fixedly mounted on the lower end of the mounting plate 5, and a drive wheel 7 fixedly connected to one end of the output shaft of the drive motor 6, and the mounting plate 5 is inclined downward toward the cutting blade 4;

[0032] The upper surface of the base 1 is provided with a linkage anti-deviation mechanism, which adjusts the fabric in real time by monitoring the fabric deviation to ensure that the fabric is cut in a relatively flat state. The linkage anti-deviation mechanism includes: a blocking sensor 8, which is embedded in the upper surface of the base 1; a connecting electric push rod 9 is fixedly installed on the surface of the mounting plate 5, and a linkage plate 10 is fixedly connected to the lower end of the connecting electric push rod 9; an adjusting motor 11 is fixedly installed on the outer surfaces of both ends of the linkage plate 10, and an adjusting rod 12 is fixedly connected to one end of the output shaft of the adjusting motor 11; a sliding block 13 is installed on the outer surface of the adjusting rod 12, and a pressing block 14 is fixedly installed at the lower end of the sliding block 13; a rotating flipping frame 15 is installed at the lower end of the linkage plate 10; a sliding sliding frame 16 is installed at equal intervals at the lower end of the flipping frame 15; a positioning motor 18 is fixedly installed on the side surface of one side of the sliding frame 16, and a positioning wheel 17 is fixedly connected to one end of the output shaft of the positioning motor 18.

[0033] The adjusting rod 12 and the sliding block 13 are threadedly connected, the adjusting rod 12 and the linkage plate 10 are rotatably connected, and the linkage plate 10 and the sliding block 13 are slidably connected.

[0034] The extrusion block 14 is an isosceles trapezoidal design, and the inclined surface of the extrusion block 14 faces one end of the flipping frame 15, and the end of the flipping frame 15 facing the extrusion block 14 has an arc-shaped chamfer design.

[0035] A spring connects the tilting frame 15 to the linkage plate 10, and a spring also connects the tilting frame 15 to the sliding frame 16.

[0036] During use, the fabric is passed between the drive wheel 7 and the base 1. The drive motor 6 drives the drive wheel 7 to rotate, causing the fabric to move on the upper surface of the base 1. When the fabric moves to the predetermined position below the cutting blade 4, the cutting hydraulic rod 3 on the mounting frame 2 drives the cutting blade 4 to move downward to cut the fabric.

[0037] When the fabric shifts during movement and blocks the obstruction sensor 8, the obstruction sensor 8 is triggered and sends an electrical signal to the connected electric push rod 9 and the adjusting motor 11. The adjusting motor 11 drives the sliding block 13 and the squeezing block 14 to slide laterally via the adjusting rod 12. The squeezing block 14 squeezes the flipping frame 15 on one side of the fabric's shift direction via an inclined surface. The flipping frame 15 rotates, causing the positioning wheel 17 at the lower end of the flipping frame 15 to contact the fabric. Since the mounting plate 5 is installed at an angle, the number of positioning wheels 17 in contact with the fabric will increase as the connected electric push rod 9 drives the linkage plate 10 downward. As the sliding increases, the positioning motor 18 drives the positioning wheel 17 to rotate, so that the fabric can be pushed inward and reset. The sliding frame 16 slides relative to the flipping frame 15 so that the positioning wheel 17 that comes into contact with the fabric first will not be squeezed and damaged. It can be adjusted according to the degree and position of the fabric offset. When different parts of the fabric are offset to both sides, the squeezing blocks 14 at both ends move in opposite directions to squeeze the flipping frame 15, so that the flipping frames 15 on both sides can adjust and position the fabric in a targeted manner by flipping downward in a linked manner.

[0038] Example 2

[0039] This embodiment discloses, based on embodiment 1, that: a docking block 19 and a docking rod 20 are respectively fixedly provided on the outer surface of one side of the two sliding frames 16 facing each other, and the docking block 19 and the docking rod 20 are snap-fitted together. One end of the docking rod 20 is a triangular design, and the docking rod 20 and the docking block 19 are in clearance fit.

[0040] A contact plate 21 is fixedly provided on the outer surface of one end of the linkage plate 10 connected to the flipping frame 15, and a contact switch 22 is fixedly installed on the outer surface of the flipping frame 15 below the contact plate 21.

[0041] The upper end of the contact switch 22 is in contact with the lower surface of the contact plate 21, and one end of the linkage plate 10 where the contact plate 21 is located protrudes and is in contact with the upper surface of one end of the flipping frame 15.

[0042] When the positioning wheels 17 alternately contact the fabric, the docking rod 20, through the gap fit with the docking block 19, allows the adjacent positioning wheels 17 to shift vertically to a certain extent without disconnecting, thereby ensuring that all positioning wheels 17 can be driven to rotate synchronously.

[0043] During the rotation of the tilting frame 15, the contact switch 22 on the upper surface of the tilting frame 15 loses the pressure of the contact plate 21, and the contact switch 22 sends an electrical signal to the positioning motor 18 to enable the positioning motor 18 to start automatically when needed.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
