Description

Technical Field

[0001] The utility model relates to the technical field of woven bag processing, and particularly relates to a cloth rolling and flattening mechanism for woven bag processing. Background Technique

[0002] A woven bag, also known as a snake skin bag, is a type of plastic bag used for packaging. Its raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. The weaving density refers to the number of warp and weft yarns within a 100mm×100mm woven fabric. When processing woven bags, cloth rolling is required. However, it is laborious to flatten the rolled cloth manually, so a cloth rolling and flattening mechanism is needed. The flattening mechanism refers to unfolding the wound item and performing a leveling treatment on the unfolded cloth to make the cloth more flat.

[0003] After retrieval, a cloth rolling and flattening mechanism for woven bag processing with the publication number CN218434180U specifically discloses a cloth rolling and flattening mechanism for woven bag processing, including a base. One side of the top surface of the base is provided with a fixed plate, and a magnet is arranged on the top surface of the fixed plate. The two top ends of the base are provided with guide grooves, and a moving frame is movably connected in the guide grooves. In the utility model, a fixed plate is fixedly installed on one side of the top surface of the base, and a magnet is adsorbed on the top surface of the fixed plate. By using the magnet to adsorb the fixed plate, the woven bag raw material is placed between the magnet and the fixed plate, and the magnet adsorbs the fixed plate, thereby clamping and fixing the woven bag on the top surface of the base, thus avoiding clamping the woven bag on the bottom surface of the base by bolts through a clamping plate, shortening the operation time and simplifying the operation steps.

[0004] In the above patent, specifically, a motor drives a gear to rotate, drives a rack to move, thereby controlling the displacement of the moving frame, and the rollers rotate, so as to flatten the woven bag raw material on the top surface of the base. However, when the rolled cloth is laid flat on the operating table, due to the light weight of the rolled cloth and the long-term winding situation, the flatness of the rolled cloth is poor, and it is easy to be uneven when laid flat, which affects the accuracy of the subsequent cloth size positioning and the flatness when overlapping with the woven bag, and is likely to affect the quality of the finished product.

[0005] Therefore, it is very necessary to invent a cloth rolling and flattening mechanism for woven bag processing to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a cloth rolling and flattening mechanism for woven bag processing to solve the problems raised in the above background technique.

[0007] To achieve the above object, the utility model provides the following technical solution: A cloth rolling and flattening mechanism for woven bag processing, comprising a housing, a flattening mechanism and a fixing mechanism. The flattening mechanism includes a top plate, a hydraulic cylinder, a frame body, a rotating rod and a pressing roller. The top plate is arranged at the upper end of the housing, the hydraulic cylinder is arranged at the upper end of the top plate, the frame body is fixedly installed at the lower end of the hydraulic cylinder, one side of the frame body is connected with the rotating rod, and the pressing roller is arranged on the outer wall of the rotating rod.

[0008] Preferably, an operating table is arranged at the upper end of the housing, electric slide rails are arranged on both sides of the operating table, sliders are movably connected to the outer walls of the electric slide rails, and a bracket is fixedly installed on the other side of the sliders.

[0009] Preferably, there are two groups of the electric slide rails, and the two groups of electric slide rails are symmetrically distributed on both sides of the operating table, and the two groups of electric slide rails are symmetrically distributed about the central axis of the operating table.

[0010] Preferably, one side of the bracket is connected with a transmission rod, one end of the transmission rod is connected with a driving motor, and a winding drum is arranged on the outer wall of the transmission rod.

[0011] Preferably, a measuring scale is arranged at the upper end of the operating table, a sliding groove is opened on one side surface of the measuring scale, a sliding block is movably connected to the inner wall of the sliding groove, and a positioning rod is fixedly installed on the other side of the sliding block.

[0012] Preferably, the fixing mechanism includes a connecting rod, a rotating shaft, a pressing strip, a pressing rod, a magnet and a fixing groove. The connecting rod is arranged at the upper end of the operating table, the rotating shaft is movably connected to the outer wall of the connecting rod, the pressing strip is fixedly installed on one side of the rotating shaft, the pressing rod is fixedly installed on one side of the pressing strip, the magnet is arranged at the lower end of the pressing rod, and the fixing groove is opened on the upper surface of the operating table.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] 1. Through the settings of the top plate, hydraulic cylinder, frame body, rotating rod and pressing roller, the top plate is fixed to the bracket, playing a role of fixed support between the hydraulic cylinder and the pressing roller. The hydraulic cylinder can adjust the descending height of the pressing roller according to the thickness of the rolled fabric, so that the pressing roller fits with the rolled fabric, facilitating the subsequent operation of the pressing roller to press and flatten the surface of the rolled fabric in cooperation with the electric slide rail. The rotating rod can drive the rotation and rolling between the pressing roller and the rotating rod through the frictional force generated when the pressing roller contacts the rolled fabric, improving the leveling effect of the pressing roller. Moreover, during the process of the pressing roller contacting the rolled fabric, since the bracket is driven by the electric slide rail to slide, and the frame body is fixedly installed with the bracket, the pressing roller will also slide accordingly during the movement of the bracket. Thus, the inertia generated during the sliding process drives the pressing roller to rotate, further improving the flexibility of the pressing roller in use, enabling the pressing roller to level the uneven positions on the rolled fabric;

[0015] 2. Through the settings of the connecting rod, rotating shaft, pressing strip, pressing rod, magnet and fixing groove, the setting of the rotating shaft can drive the pressing strip to rotate. When it is necessary to use the pressing strip to fix the rolled fabric to the operating table, manually rotate the pressing strip to make it descend, and fix one end of the pressing strip to the fixing groove during the descending process of the pressing strip, improving the stability of the fixing of the pressing strip. Secondly, the magnet arranged on the pressing strip can fix the rolled fabric to the operating table, and the fixing is stronger, making it more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

The flattening mechanism 9 includes a top plate 901, a hydraulic cylinder 902, a frame 903, a rotating rod 904 and a pressing roller 905. The top plate 901 is arranged at the upper end of the outer shell 1, the hydraulic cylinder 902 is arranged at the upper end of the top plate 901, the lower end of the hydraulic cylinder 902 is fixedly installed with a frame 903, one side of the frame 903 is connected with a rotating rod 904, and a pressing roller 905 is arranged on the outer wall of the rotating rod 904.

[0025] As Figure 1 and Figure 3 shown, an operating table 2 is arranged at the upper end of the outer shell 1, electric slide rails 3 are arranged on both sides of the operating table 2. There are two groups of electric slide rails 3, and the two groups of electric slide rails 3 are symmetrically distributed on both sides of the operating table 2. The two groups of electric slide rails 3 are symmetrically distributed about the central axis of the operating table 2. The arrangement of the electric slide rails 3 can slide and flatten the unrolled cloth, replacing the inconvenience of manual flattening. The outer wall of the electric slide rail 3 is movably connected with a slide block 4, and the other side of the slide block 4 is fixedly installed with a bracket 5. The slide block 4 slides on the outer wall of the electric slide rail 3, driving the bracket 5 to slide left and right, facilitating the stretching of the cloth dropped from the pay-off reel 8 on the bracket 5.

[0026] As Figure 1 and Figure 3 shown, one side of the bracket 5 is connected with a transmission rod 6, one end of the transmission rod 6 is connected with a driving motor 7, and a pay-off reel 8 is arranged on the outer wall of the transmission rod 6. The pay-off reel 8 is used in cooperation with the driving motor 7, and can quickly unwind the cloth.

[0027] As Figure 1-2As shown in the figure, a measuring scale 10 is provided at the upper end of the operating table 2. A chute 11 is provided on one side surface of the measuring scale 10. A sliding block 12 is movably connected to the inner wall of the chute 11. A positioning rod 13 is fixedly installed on the other side of the sliding block 12. The measuring scale 10 can measure the length of the unrolled fabric after flattening, which is convenient for determining the required length of the fabric.

[0028] As Figure 1 and Figure 4 As shown in the figure, the fixing mechanism 14 includes a connecting rod 1401, a rotating shaft 1402, a pressing strip 1403, a pressing rod 1404, a magnet 1405 and a fixing groove 1406. A connecting rod 1401 is provided at the upper end of the operating table 2. The outer wall of the connecting rod 1401 is movably connected to a rotating shaft 1402.

During the process of pressing down the pressing strip 1403, the pulled fabric is fixed between the fabric and the operating table 2 through the magnet 1405. After one end of the fabric is fixed, turn on the switch of the hydraulic cylinder 902 to drive the frame 903 to descend. After the pressing roller 905 on the frame 903 touches the fabric, turn off the switch of the hydraulic cylinder 902. Secondly, turn on the switch of the driving motor 7 to drive the unwinding reel 8 to unwind the fabric through the transmission rod 6. After the fabric is unwound to a certain extent, first turn off the switch of the driving motor 7, and then turn on the switch of the electric slide rail 3 to drive the frame 903 to slide. During the sliding process of the frame 903, the unwound fabric is flattened. After the fabric is flattened, according to the length of the fabric required for cutting the woven bag, slide the positioning rod 13 to measure and position the required cutting length of the fabric, which is convenient for subsequent cutting of the fabric. After one end of the fabric is cut, reset the frame 903 through the electric slide rail 3, and then remove the cut fabric on the operating table 2. Repeat the above steps for flattening and processing. Finally, when the device is not in use, cut off the power switch of the device.
