Description

Technical Field

[0001] The utility model relates to the technical field of woven bag production, in particular to a winding device for producing woven bags which can be cut by themselves. Background Art

[0002] In the production process of woven bags, after the woven bags are woven, a winding device is needed to wind up the woven bags, so as to facilitate the storage and delivery of the woven bags. For example, in the patent number "CN220502145U" and the patent name "A woven bag winding machine", two second support frames are fixed on the bottom plate, one end of the two lead screws is rotatably connected to the second support frame, and the other end of the two lead screws is rotatably connected to the bottom plate, so that the second support frame and the bottom plate cooperate to support the lead screw, so that the lead screw can rotate in the second support frame. By putting the moving block on the outside of the lead screw, and connecting the two moving blocks to the two ends of the tensioning assembly to realize the rotation of the lead screw, the lead screw drives the moving block and the tensioning assembly to move up and down. With the above structure, the woven bag is first passed through the tensioning assembly, and then the lead screw is rotated to drive the moving block and the tensioning assembly to move upward, so that the woven bag is in a tensioned state to improve the winding effect of the woven bag. However, the above structure still has the following problems in actual use:

[0003] Although the above structure keeps the woven bag in a tensioned state through the tensioning component to improve the rolling effect of the woven bag, after rolling to a certain amount, the woven bag needs to be cut manually with a knife before the rolled woven bag can be taken down. This requires workers to pay attention at all times. After the woven bag is rolled up, it must be cut as soon as possible and then a new winding roller must be replaced. If cutting is not performed in time, the work efficiency will be greatly reduced.

[0004] Therefore, we proposed a self-cutting woven bag production winding device that can solve the above problems well. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-Figure 7 , the utility model provides the following technical solutions:

[0033] Embodiment 1: In order to solve the problem that the woven bag winding device proposed in the prior art needs to be manually cut with a knife before the rolled woven bag can be taken down after the woven bag is rolled to a certain amount, and if the cutting is not performed in time, it is easy to greatly reduce the work efficiency, the following scheme is disclosed, including a base 1, and a mounting plate 2 is fixed to the upper surface of the base 1; it also includes: a lifting rod 5 is arranged on the upper surface of the base 1, and the lifting rod 5 is slidably connected with the base 1 through a reset spring 7, and the two ends of the reset spring 7 are respectively fixed to the base 1 and the lifting rod 5; a contact plate 6 is fixed to the upper end of the lifting rod 5, and the lower end of the lifting rod 5 is in contact with a pressure sensor 8, and the pressure sensor 8 is fixed The base 1 is fixed inside, and the pressure sensor 8 is connected to the PLC controller 10 through the transmission line 9, and the PLC controller 10 is fixed inside the base 1, and the PLC controller 10 is connected to the cylinder 12 through the transmission line 9; the mounting sleeve 11 is fixedly mounted on the upper surface of the base 1, and the cylinder 12 is fixedly mounted inside the mounting sleeve 11, and the upper end of the cylinder 12 passes through the top of the mounting sleeve 11 and is fixed to the connecting plate 13, and the lower surface of the connecting plate 13 is fixedly mounted with a cutting knife 14, the mounting plate 2 is provided with two groups, and the rear side of the rear mounting plate 2 is bolted with a servo motor 3, and the output end of the servo motor 3 is fixed with a winding roller 4, and the front end of the winding roller 4 is connected to the bearing of the mounting plate 2;

[0034] By starting the servo motor 3, the servo motor 3 drives the winding roller 4 to rotate, so that the winding roller 4 winds up the woven bag. During the winding process of the woven bag, its inner diameter will gradually increase, so that the woven bag rolled into a cylindrical shape will contact the extrusion contact plate 6, so that the contact plate 6 is forced to drive the lifting rod 5 to slide downward, so that the lower end of the lifting rod 5 squeezes the pressure sensor 8, and the pressure sensor 8 triggers the signal to be sent to the PLC controller 10 through the transmission line 9. The PLC controller 10 receives the information and controls the cylinder 12 to start through the transmission line 9, so that the cylinder 12 drives the upper connecting plate 13 downward, so that the connecting plate 13 drives the cutting knife 14 to approach the bearing seat 15, and the cutting knife 14 is matched with the cutting groove 16 on the bearing seat 15, so as to achieve the effect of cutting the woven bag in the middle, so that the woven bag can be cut by itself after being rolled to a certain amount, so that there is no need for manual cutting, and failure to cut in time is avoided, thereby improving the work efficiency;

[0035] Embodiment 2: Different from Embodiment 1, this embodiment facilitates the resetting of the cutting knife 14 and can prevent the woven bag from touching the cutting knife 14 during the rolling process. Figure 1-Figure 3 and Figure 7The contact plate 6 is arranged in an arc-shaped structure, and the upper surface of the contact plate 6 contacts the woven bag. Two groups of mounting sleeves 11 are arranged, and a bearing seat 15 is fixed on the inner side of the mounting sleeve 11, and a cutting groove 16 is opened on the upper surface of the bearing seat 15, and the cutting groove 16 is matched with the cutting knife 14. A limiting roller mechanism 17 is fixedly installed on the upper surface of the left base 1 of the mounting sleeve 11, and the limiting roller mechanism 17 is composed of two groups of limiting rollers;

[0036] After the rolled woven bag is taken away, the woven bag no longer contacts the extrusion contact plate 6. At this time, the elastic force of the reset spring 7 drives the lifting rod 5 and the contact plate 6 to reset, so that the lower end of the lifting rod 5 no longer squeezes the pressure sensor 8. At this time, the pressure sensor 8 transmits a signal to the PLC controller 10 again through the transmission line 9. The PLC controller 10 receives the signal and then controls the cylinder 12 through the transmission line 9 to drive the connecting plate 13 and the cutting knife 14 to reset, so as to facilitate the next use. Moreover, before the woven bag is rolled onto the winding roller 4, it will first pass through the limiting roller mechanism 17. The limiting roller mechanism 17 is composed of two groups of limiting rollers. The woven bag passes between the two groups of limiting rollers, which can play the effect of limiting the woven bag, not only to avoid the woven bag from deflecting, but also to avoid the woven bag from touching the cutting knife 14 during the rolling process, and to avoid the cutting knife 14 from scratching the woven bag.

[0037] Embodiment 3: Different from Embodiment 2, this embodiment can smooth the woven bag. Figure 2 and Figure 4 The upper surface of the base 1 is provided with a connecting slider 18, and the connecting slider 18 is slidably connected to the base 1 through a pressure spring 19, and the two ends of the pressure spring 19 are respectively fixed to the base 1 and the connecting slider 18, the upper end surface of the connecting slider 18 is rotatably connected with a connecting rod 20, and a smoothing roller 21 is fixed to the inner side of the upper end of the connecting rod 20, two groups of connecting rods 20 are provided, and each group of connecting rods 20 is provided with two, and the two connecting rods 20 are connected by a stabilizing connecting rod 22, and the stabilizing connecting rod 22 and the connecting rod 20 are rotatably connected;

[0038] Moreover, when the winding roller 4 is winding the woven bag, as its inner diameter increases, it will also contact the smoothing roller 21, and the smoothing roller 21 will be squeezed by the woven bag roll, so that the smoothing roller 21 drives the connecting rod 20 to move downward, and the other end of the connecting rod 20 forms a rotational connection with the connecting slider 18, so that the connecting slider 18 slides outward, and then squeezes the pressure spring 19. The elastic force generated by the pressure spring 19 generates a thrust on the connecting slider 18, so that the connecting slider 18 drives the smoothing roller 21 to always contact the woven bag through the connecting rod 20, thereby smoothing the woven bag, and the two groups of connecting rods 20 are connected by a stabilizing connecting rod 22, thereby increasing the stability between the two groups of connecting rods 20 and ensuring that the smoothing roller 21 is always in contact with the woven bag.

[0039] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
