Description

Technical Field

[0001] The utility model relates to the field of non-woven bags, in particular to a non-woven bag folding machine. Background Art

[0002] A non-woven bag is a bag made of non-woven fabric. It is a reusable environmentally friendly bag that is widely used in supermarkets, shopping malls, exhibitions and other occasions. Non-woven fabric is a new type of fiber product. It is directly formed by polymer chips, short fibers or filaments through various fiber web forming methods and consolidation technologies. It has the characteristics of softness, breathability and planar structure. Non-woven fabric needs to be folded when it is made into a non-woven bag, which requires a folding machine. The folding machine is a machine that processes the edges of the product. Its main function is to process the surface of the material into curved shapes such as corners.

[0003] After searching, a non-woven bag folding machine with a publication number of CN218020479U is found, which specifically discloses a non-woven bag folding machine, including a placing rack, a folding plate, a folding mechanism and a distance adjusting mechanism. The placing rack includes a frame and a discharge plate, the discharge plate is fixedly installed on the front and rear inner walls of the frame, the folding plate is located on the top of the discharge plate, the folding plate is arranged in an arc shape, and the folding mechanism includes a rotating component and a thickness adjusting component. The non-woven bag folding machine can quickly fold one side of the non-woven fabric with the folding plate, and can also drive the abutment plate to move left and right, which is convenient for adjusting the size of the folding edge, so that one side of the non-woven fabric is bent according to a specified length to meet the user's use needs. The folding plate can also be driven to rise and fall, and the distance between the folding plate and the discharge plate can be adjusted, which is convenient for bending non-woven fabrics of different thicknesses. Moreover, the folding plate is arranged in a curved manner, and it is easy to push one side of the non-woven fabric between the discharge plate and the folding plate, which is convenient for loading and unloading non-woven fabrics.

[0004] During the use of the existing non-woven bag folding machine, since the non-woven fabric is not a hard material, there will be obvious creases after folding like paper. In the process of making the non-woven fabric into the bag, it is necessary to repeatedly fold and pressurize to complete the folding, which is convenient for subsequent folding and constant pressure work. In addition, if the above-mentioned comparative case only relies on folding once, it cannot meet the folding requirements of the non-woven bag. In this way, in the long-term batch production of non-woven bags, the folded non-woven fabric needs to be folded twice or even repeatedly in order to deepen the creases, which delays the overall production time of the non-woven bag.

[0005] Therefore, it is necessary to invent a nonwoven bag folding machine to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a non-woven bag folding machine, which can enhance the crease effect through an edge-raising roller, an edge-folding frame, a hot pressing frame, a gantry frame and a first re-pressing roller, so that the device can complete the folding work of the non-woven bag. In this way, the coordinated use not only enhances the folding effect of the device on the non-woven fabric, but also avoids the tedious operation of repeating the folding process of the folded non-woven fabric for a second time or even multiple times, thereby improving the overall production time efficiency of the non-woven bag, and making the non-woven bag after the folding of the device more convenient for subsequent constant pressure and other work, so as to solve the problem of no During the use of the woven bag folding machine, since the non-woven fabric is not a hard material, there will be obvious creases after folding like paper. In the process of making the non-woven fabric into the bag, it is necessary to repeatedly fold and pressurize to complete the folding, which is convenient for subsequent folding and constant pressure work. In addition, if only one folding is relied on in the above comparative case, the folding requirements of the non-woven bag cannot be met. In this way, in the long-term batch production of non-woven bags, the folded non-woven fabric needs to be folded twice or even repeatedly in order to deepen the creases, which delays the overall production timeliness of the non-woven bag.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figure 1-5 A non-woven bag folding machine shown includes a machine body 1 for carrying and installing components for folding the non-woven bag;

[0029] A leveling frame 4 is arranged above the machine body 1 and is used for leveling the non-woven fabric before folding the edge. An edge raising plate 9 is arranged outside the leveling frame 4. A fixed slide rail 10 is arranged outside the edge raising plate 9. A fixed slide sleeve 11 is movably connected to the outside of the fixed slide rail 10.

A first telescopic cylinder 19 is arranged above the hot pressing frame 17, and a hot pressing plate 20 is fixedly installed at one end of the first telescopic cylinder 19;

[0031] The gantry 21 is arranged on one side of the hot pressing frame 17, and is used for completing the secondary re-pressing of the non-woven bag. The gantry 21 is internally movably connected with a first re-pressing roller 22. A second telescopic cylinder 23 is fixedly installed above the gantry 21, and a second re-pressing roller 24 is fixedly installed at one end of the second telescopic cylinder 23. The non-woven fabric after the initial folding will continue to enter the gantry 21, and the second re-pressing roller 24 is driven by the second telescopic cylinder 23 to strengthen the force of approaching the first re-pressing roller 22. The creases of the non-woven fabric are shaped and the crease effect is strengthened through rolling re-pressing, so that the device can complete the folding work of the non-woven bag.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a placing rack 2 is fixedly installed on the top of the machine body 1, and a non-woven bag roller 3 is movably connected inside the placing rack 2. The placing rack 2 can facilitate the operator to place the non-woven fabrics that need to be folded on the non-woven bag roller 3 in batches, without the need to fold one and then discharge the material, thereby speeding up the folding efficiency of the entire non-woven fabric. The first smoothing roller 5 is movably connected inside the leveling rack 4, and a first screw 6 runs through the top of the leveling rack 4. A connecting block 7 is fixedly installed on one end of the first screw 6, and a second smoothing roller 8 is arranged on one side of the connecting block 7. The leveling rack 4 can freely adjust the spacing between the first smoothing roller 5 and the second smoothing roller 8, so as to smooth out the wrinkles and marks of the non-woven fabric before folding, so that the subsequent folding components can better complete the folding work of the non-woven bag, the edge roller 13 is movably connected to the edge plate 9, and the fixed slide sleeve 11 is used in conjunction with the fixed slide rail 10. The edge roller 13 can limit the edge of the non-woven fabric passing through, and cooperate with the edge plate 9 to complete the edge folding work of the non-woven fabric.

[0034] The practical working principle of the present invention is as follows: firstly, an external power supply is connected, and the non-woven fabric bags that need to be folded are taken out, and the non-woven fabrics can be wound around the non-woven fabric bag roller 3 in batches, so that there is no need to fold the edges one by one before unloading the materials, thereby speeding up the folding efficiency of the entire non-woven fabric; then, one end of the non-woven fabric is pulled, and the non-woven fabric is passed through the flattening frame 4, the folding frame 14 and the gantry frame 21 and wound onto the winding roller 27 of the winding frame 25, so that as the winding roller 27 rotates, the device can automatically fold the entire non-woven fabric, thereby greatly improving the production efficiency of the non-woven fabric bags; then, according to the current thickness and flattening requirements of the non-woven fabric, the first screw is twisted. The rod 6 adjusts the distance between the first smoothing roller 5 and the second smoothing roller 8, so as to smooth out the wrinkles and marks of the non-woven fabric before folding, so that the subsequent folding components can better complete the folding work of the non-woven bag, and then adjust the position of the edge roller 13 according to the size and position of the folding mark, and twist the second screw 15 to adjust the angle of the folding side plate 16. After the preparation work is completed, the folding work of the non-woven bag can be started. As the non-woven fabric is rolled up, the non-woven bag is first smoothed by the first smoothing roller 5 and the second smoothing roller 8, and then the edge roller 13 can limit the edge of the non-woven fabric passing through, and cooperate with the edge plate 9 to After the hemming of the non-woven fabric is completed, the switch of the first telescopic cylinder 19 is turned on, and the first telescopic cylinder 19 drives the hot pressing plate 20 to close to the bottom pressing plate 18, so as to fold the non-woven fabric after the hemming, deepen the crease effect, and the hot pressing can make the hemming effect of the non-woven fabric more obvious, and at the same time can reduce the probability of crease rebound, and then the non-woven fabric after the initial hemming will continue to enter the gantry 21, and then the switch of the second telescopic cylinder 23 is turned on, and the second telescopic cylinder 23 drives the second re-pressing roller 24 to strengthen the force of approaching the first re-pressing roller 22, and the crease of the non-woven fabric is finalized and strengthened by rolling re-pressing, and the non-woven fabric is completed. The bag folding work not only enhances the folding effect of the device on the non-woven fabric, but also avoids the tedious operation of repeating the folding process of the folded non-woven fabric for a second time or even multiple times, thereby improving the overall production time efficiency of the non-woven bag. Next, the folded non-woven bag is rotated and rolled up by the winding roller 27, so that the entire non-woven fabric folding process is completed, and the non-woven bags can be batch folded. Finally, after completing all the non-woven bag folding work according to the above operation, turn off the switches of the first telescopic cylinder 19 and the second telescopic cylinder 23. If it is not used for a long time, cut off the external power supply. In this way, the use process of the non-woven bag folding machine is completed.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
