Description

Technical Field

[0001] The utility model relates to the technical field of woven bag production equipment, and particularly relates to a material roll winding device for producing woven bags. Background Technique

[0002] A woven bag, also known as a snake skin bag, is a kind of plastic used for packaging. Its raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. Woven bags have a wide range of uses and are mainly used for the packaging and loading of various items, and are widely used in the industrial field. During the production of woven bags, the rolled woven bag production fabric is cut and sewn to finally form a woven bag.

[0003] After the woven bag production fabric is produced, it needs to be wound into a roll by a material roll for the transportation, storage and feeding of the woven bag production fabric. In the prior art, the winding and winding equipment for the woven bag production fabric usually uses a tensioning wheel before winding for tensioning. Since the angular velocity of the material roll is the same, the diameter of the woven bag production fabric gradually becomes larger after being wound and wound on the material roll. Therefore, during the winding process, the winding tightness of the woven bag production fabric is inconsistent. Secondly, the connection between the material roll and the driving device by a conventional coupling is not convenient to disassemble, reducing the replacement efficiency of the material roll.

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] As Figures 1 to 6 shown, a material roll winding device for producing woven bag materials includes a base 1. Two groups of roller seats 2 are symmetrically arranged on the top of the base 1. A material roll 9 is arranged on the tops of the two groups of roller seats 2. A driving motor 4 and a speed reducer 5 cooperatively connected with the driving motor 4 are further arranged on the base 1. The speed reducer 5 is transitionally connected with the material roll 9 through a coupling device 6.

[0036] Specifically in this embodiment, as Figure 5 shown, two symmetrically arranged support seats 7 are arranged on the top of the base 1. The two groups of roller seats 2 are respectively fixed on the tops of the corresponding support seats 7. In this embodiment, a group of roller seats 2 includes two symmetrically arranged runners with parallel axes. The two runners are respectively arranged on the same wheel seat and integrally form a group of roller seats 2. The roller shafts at both ends of the material roll 9 are respectively lapped on the two groups of corresponding roller seats 2. The roller shaft at each end of the material roll 9 is located between the two runners in a group of roller seats 2. When the material roll 9 is not connected to the coupling device 6, the material roll 9 can be directly taken out from the top of the roller seat 2.

[0037] Further, a limiting plate 71 is arranged on the support seat 7 at the end far from the coupling device 6. The limiting plate 71 is located on one side of the corresponding roller seat 2. The limiting plate 71 forms a horizontal limit for the material roll 9 to prevent the material roll 9 from horizontally moving on the roller seat 2 and slipping off.

[0038] In this embodiment, the speed reducer 5 is fixed on the base 1 through a connecting seat (not shown in the figure).

[0039] As a specific implementation manner, as Figure 5 shown, the coupling device 6 includes a key shaft fixing cylinder 61. A key shaft 62 is slidably arranged in the key shaft fixing cylinder 61. A second key groove 91 matched with the key shaft 62 is arranged on the roller shaft of the material roll 9. A limiting mechanism for limiting the key shaft 62 is arranged between the key shaft fixing cylinder 61 and the key shaft 62. The key shaft fixing cylinder 61 is cooperatively connected with the power output shaft of the speed reducer 5 through a speed reducer connecting shaft 63.

[0040] Specifically in this embodiment, a slideway 611 is penetrated through the key shaft fixing cylinder 61. The key shaft 62 is slidably arranged in the slideway 611.

[0041] Specifically in this embodiment, the limiting mechanism includes second ear plates 621 symmetrically arranged on both sides of the key shaft 62. An avoidance groove 612 communicating with the slideway 611 and for the second ear plate 621 to slide through is provided on the key shaft fixing cylinder 61. First ear plates 613 corresponding to the second ear plates 621 are respectively arranged on both sides of the avoidance groove 612. First limiting holes 615 and second limiting holes 622 arranged horizontally are respectively provided between the first ear plate 613 and the second ear plate 621. The first limiting holes 615 and the second limiting holes 622 are fixedly connected by a pin (not shown in the figure), thereby preventing the key shaft 62 from sliding within the key shaft fixing cylinder 61, completing the horizontal limitation of the key shaft 62, preventing the key shaft 62 from falling off after being inserted into the corresponding second key groove 91, and ensuring the connection stability between the speed reducer 5 and the material roller 9.

[0042] Specifically in this embodiment, one end of the speed reducer coupling 63 facing the speed reducer 5 is provided with a first key groove 631 adapted to the power output shaft of the speed reducer 5. The end of the speed reducer coupling 63 away from the speed reducer 5 is provided with a second flange plate 632. One end of the key shaft fixing cylinder 61 facing the speed reducer coupling 63 is provided with a first flange plate 614 corresponding to the second flange plate 632. The first flange plate 614 and the second flange plate 632 are fixedly connected by bolts.

[0043] Preferably, the extension length of the second ear plate 621 towards the outside is greater than that of the first ear plate 613 towards the outside, so that the second ear plate 621 can be directly contacted and moved to adjust the position of the key shaft 62.

[0044] A pressing roller 3 is rotatably arranged on the base 1 and below the material roller 9. An elastic member for preventing the pressing roller 3 from moving away from the material roller 9 is further provided between the pressing roller 3 and the base 1.

[0045] As a specific implementation manner, as Figure 1 shown, the pressing roller 3 is hinged to the base 1 through a support rod 31. Specifically, two hinge seats 11 are provided on the base 1. Two support rods 31 are used. One ends of the two support rods 31 are respectively hinged to the corresponding hinge seats 11. The other ends of the support rods 31 extend towards the material roller 9. Both ends of the pressing roller 3 are rotatably connected to the suspended ends of the corresponding support rods 31.

[0046] Specifically in this embodiment, the elastic member is a tension spring 8. A vertical frame 12 extending upwards is provided on the base 1. A connecting rod 32 is provided between the two support rods 31. One end of the tension spring 8 is connected to the top end of the vertical frame 12, and the other end of the tension spring 8 is connected to the connecting rod 32.

[0047] Working principle: When in use, when installing the material roller 9, first move the key shaft 62 to the side close to the speed reducer 5 to ensure that the material roller 9 can be smoothly placed on the tops of the two idler supports 2, avoiding interference of the key shaft 62 with the installation of the material roller 9. After the material roller 9 is placed on the tops of the two idler supports 2, rotate the material roller 9 to an angle where the key shaft 62 can be inserted into the second keyway 91, then move the key shaft 62 and insert the key shaft 62 into the second keyway 91. Finally, insert a pin between the corresponding first limit hole 615 and the second limit hole 622 to complete the connection and fixation between the key shaft 62 and the material roller 9.

[0048] Wind the winding end of the woven bag production fabric around the material roller 9. Under the pulling force of the tension spring 8, the pressing roller 3 simultaneously clings to the bottom of the material roller 9 and presses the woven bag production fabric. Control the operation of the driving motor 4. The driving motor 4 drives the material roller 9 to rotate and wind up the woven bag production fabric through the speed reducer 5 and the coupling device 6 in sequence. Under the pressure and guiding action of the pressing roller 3, the woven bag production fabric is tightly and neatly wound around the material roller 9. As the fabric is wound, the diameter of the fabric roll gradually becomes larger. The pressing roller 3 adaptively extends within the elastic range of the tension spring 8, and the support rod 31 gradually rotates downward to ensure that the pressing roller 3 always adheres to the woven bag production fabric wound outside the material roller 9.

[0049] After the material winding is completed, pull out the pin and move the key shaft 62 away from the second keyway 91. At this time, the wound woven bag production fabric can be directly transported away from the idler support 2.

[0050] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
