[0026] The utility model will be further described below in conjunction with the accompanying drawings.

[0027] In industrial production, many jobs require workers to operate or carry some equipment with their hands. In order to protect the workers' hands from injury, they need to wear work gloves. In many cases, labor protection gloves are the most popular, mainly because they are strong, durable and low-cost. Labor protection gloves are mainly made of canvas and lining cloth materials. The lining cloth is mainly made of recycled sheets, clothes and other fabrics. After cleaning and disinfection, it is cut and spliced ​​into long strips with the same width as the canvas, and then overlapped with the canvas. After locking and sewing, it is made into labor protection gloves. In the prior art, the processing of labor protection gloves is mainly divided into three links. The first is to manually superimpose and align the purchased canvas and lining cloth (one side is completely aligned, which corresponds to the wrist end of the glove; the other side of the canvas is 1-3 cm more than the lining cloth, which is convenient for sewing fingers); the second is to lock the aligned edge; the third is to sew the superimposed fabrics after locking, generally two sewing machines are used to sew the entire fabric surface evenly. In the prior art for the first link, the two are manually laid flat on the workbench, and then the two are overlapped and aligned, which has low work efficiency and is prone to errors when entering the second link, resulting in the final production of the labor protection gloves cloth not being stretchy enough, and the finished labor protection gloves will be uncomfortable to wear.

[0028] In view of the problems in the prior art, the technical solution of this application designs a special labor protection glove cloth conveyor in the link of combining canvas and lining cloth, which can efficiently and accurately stack the canvas and lining cloth together, saving manpower while improving work efficiency and reducing production costs. Figure 1As shown, it specifically includes a main body 1, a first conveying assembly, and a second conveying assembly. The first conveying assembly and the second conveying assembly are both arranged on the main body 1, and the output ends of the two are parallel, so as to convey the canvas and the lining cloth respectively. The purpose of conveying them separately is to fully flatten the two during the conveying process, and then combine them together by parallel output. Since the lining cloth is a non-standard cloth, it has the characteristics of uneven cutting or uneven thickness, so the second conveying assembly is designed to include a second track fixing assembly, a correction frame 32 and an edge detection switch 6. The second track fixing assembly is installed on the correction frame 32, and the correction frame 32 is installed in the On the main body 1; the edge detection switch 6 is electrically connected to the control motor of the swing mechanism 5, and is used to correct one side of the lining cloth to be aligned with the preset position of the canvas. For example, the preset edge of the canvas leaves a distance of 2 cm without covering the lining cloth. At this time, the edge detection switch 6 is set at a position 2 cm away from the edge of the canvas to locate the edge of the lining cloth. When the edge of the lining cloth is not on the running track, the transmission track of the second track fixing assembly is changed by the swing mechanism 5, so as to adjust the edge of the lining cloth output to always be aligned with the position of 2 cm from the edge of the canvas. Because the other edge of the lining cloth needs to be locked with the canvas, the excess part can be directly cut off in the next link.

[0029] As for the transmission of canvas, since it is a standard cloth, the transmission process is relatively simple. It only needs to keep it stretched and the tension moderate during the transmission process. Therefore, the first transmission component includes a first cloth roller 21 and at least two first track fixing components. The first cloth roller 21 is used to wind the canvas. Preferably, the number of the first track fixing components is 3 and each includes a first support roller and two positioning wheels. The positioning wheels are adjustably mounted on the first support roller. The distance between the two positioning wheels is adjusted according to the width of the canvas so that the positioning wheels can just contact the two edges of the canvas. The surface of the positioning wheel in contact with the cloth can be set to an arc or a right-angle trapezoid to facilitate the cutting of the cloth. The first support roller can be set to a roller or a support bar, but the friction of the support bar is greater than that of the roller. The first track fixing component at the end of the first transmission component is flush with the output end of the second transmission component. In addition, a first tensioning mechanism 22 is set on any one of the first track fixing components or between any two of the first track fixing components. The first tensioning mechanism 22 is used to tension the cloth transmitted by the first transmission component. Specifically, the first tensioning mechanism 22 includes a pressure piece, a pressure spring, a support screw and an adjustment nut. When the first tensioning mechanism 22 is arranged on the body 1 between the two first conveyors, the pressure piece corresponds to the support piece on the body and a cloth channel is formed between the two. The support screw is fixed on the body 1. The pressure piece and the pressure spring are respectively sleeved on the support screw. The adjustment nut is threadedly connected with the support screw, and the pressure spring is located between the pressure piece and the adjustment nut. The adjustment nut is used to adjust the pressure of the pressure spring. Its working principle is to change the pressure of the pressure spring on the pressure piece by controlling the adjustment nut, thereby increasing the friction between the cloth, the pressure piece and the body, and ensuring that the cloth has a certain tension during the transmission process under the action of the end drag force.

[0030] In the present technical solution, the second conveying assembly also includes a second cloth roller 31 and a cloth loosening mechanism 4, the second cloth roller 31 is mounted on the main body 1, and the cloth loosening mechanism 4 is arranged between the second cloth roller 31 and the second rail fixing assembly, and is used for dragging the cloth on the second cloth roller 31 when the tension of the cloth transported on the second rail fixing assembly increases. According to the characteristics of uneven thickness and different materials of recycled waste cloth as lining cloth, the friction force on the second cloth roller 31 is also different, so it is difficult to ensure uniform rotation and release of the lining cloth during normal conveying work, especially when the center of gravity of the lining cloth on the second cloth roller 31 is unbalanced, the pulling force required for dragging increases, and the normal pulling force of the second conveying assembly is insufficient to support it, and excessive pulling force will also cause the lining cloth to deform, so by arranging the cloth loosening mechanism 4, stable transportation of the lining cloth can be guaranteed. Specifically, the cloth loosening mechanism 4 includes a cloth sensor 42, a first drive motor and two oppositely arranged cloth pulling rollers 41, the cloth sensor 42 is arranged between the second rail fixing assembly and the cloth pulling rollers 41, the two cloth pulling rollers 41 are arranged in parallel to form a cloth channel, and can drag the cloth to move when they are working by clamping each other; the first drive motor is respectively connected to the two cloth pulling rollers 41 to control the synchronous rotation of the two cloth pulling rollers 41; the first drive motor is electrically connected to the cloth sensor 42, and the cloth sensor 42 is arranged above the inner lining cloth. When the inner lining cloth is tensioned, the cloth sensor 42 senses the inner lining cloth, controls the first drive motor to work, and makes the cloth pulling rollers 41 work to pull out more inner lining cloth, thereby ensuring stable transportation of the inner lining cloth.

[0031] On the basis of the above embodiment, the swing mechanism 5 includes a second drive motor 52, a drive screw 53 and a swing track 51, the output end of the second drive motor 52 is connected to the drive screw 53; the correction frame 32 is connected to the body 1 through the swing track 51, and a drive nut matched with the drive screw 53 is arranged on the correction frame 32; the edge detection switch 6 is connected to the second drive motor, and is used to control the correction frame 32 to swing in a direction perpendicular to the cloth conveying direction through the second drive motor 52. For example, when the edge detection switch 6 detects that the edge of the inner lining cloth deviates from the predetermined position of the canvas (the position 1-3cm away from the edge of the canvas), the second drive motor 52 is controlled to work, driving the drive screw 53 to rotate forward and reverse, thereby driving the correction frame 32 to move along the swing track 51, so that the edge of the inner lining cloth is aligned with the predetermined position of the canvas.

[0032] In the technical solution of the present application, the second track fixing assembly includes a second support roller and at least one track fixing frame 321, and two second support rollers are arranged on a single track fixing frame 321, and each support roller is provided with a positioning wheel identical to that on the first support roller; there are two implementation methods of the technical solution, one is: the two second support rollers are respectively arranged at the upper and lower parts of the track fixing frame 321, and the inner lining cloth is conveyed in an S-shaped track on the correction frame 32, which can gradually flatten and tighten the inner lining cloth; the second is: Figure 2 The two second support rollers shown are both arranged on the upper part of the rail frame 321, and a pressure roller placement groove 322 is also arranged on the rail frame 321 between the two second support rollers. When working, it is similar to a tension mechanism and can keep the inner lining cloth under tension at all times. Preferably, the weight of the pressure roller is 200-500g.

[0033] Preferably, Figure 2 The second track fixing assembly shown also includes a track fixing pull cylinder 323, which has a flat cylindrical structure and is provided with an adjusting screw, and the adjusting screw is used to adjust the pressure of the track fixing pull cylinder 323 on the conveyed cloth. A trapezoidal extension plate is provided at the inlet end of the track fixing pull cylinder, and the bottom edge of the extension plate is connected to the track fixing pull cylinder body 1, so that even if the lining cloth is partially folded, the lining cloth can be stretched out under the clamping of the upper and lower extension plates, and enter the track fixing pull cylinder for standardized docking and transmission, thereby ensuring the stretchability and edge consistency of the lining cloth during output.

[0034] On the basis of the above embodiment, it also includes a cloth-holding mechanism, the cloth-holding mechanism 8 is arranged at the end of the body, specifically including a third drive motor and at least two mop rollers, a mop channel is formed between the two mop rollers, the two mop rollers are used to clamp the aligned and superimposed canvas and lining cloth and convey them to the next processing link, and also provide power for the conveyance of the canvas and lining cloth in the first conveying assembly and the second conveying assembly.
