Technical Field
[0001] This utility model relates to the technical field of woven bag winding equipment, and more specifically, to a plastic woven bag production winding device. Background Technology
[0002] Woven bags, also known as snake-skin bags, are a type of plastic bag used for packaging. They are typically made from various chemical plastics such as polyethylene and polypropylene. During production, woven bags are initially simple strips that need to be rolled up during use.
[0003] Currently, in practical applications, it has been found that the transmission of woven bags is deviated due to the influence of tension and winding force, resulting in issues such as protruding shoulders and uneven edges during winding.
[0004] To address the aforementioned problems, this application proposes a plastic woven bag production winding device. Utility Model Content
[0005] The purpose of this invention is to provide a plastic woven bag production winding device to solve the problem of skewed winding of woven bags in the prior art.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] A plastic woven bag production winding device includes a winding machine and a winding roller installed inside it;
[0008] The winding machine is equipped with a rolling mechanism inside, adjacent to the winding feed side of the winding roller;
[0009] The rolling mechanism includes a bidirectional transmission rod and a rotating shaft that are parallel to each other, and a screw-fit sleeve and a rotating frame are respectively provided on the outer side of the bidirectional transmission rod and the rotating shaft;
[0010] A rotating sleeve is rotatably mounted on the outer side of the screw-on sleeve, and a rolling part is provided on the outer side of the rotating sleeve;
[0011] The outer side of the rotating frame is provided with a rolling groove, and the rolling part and the side of the rolling groove make rolling contact with each other.
[0012] The screw-on sleeve and the rotating frame are a set, distributed on the upper and lower sides of the woven bag.
[0013] Preferably, the two ends of the bidirectional transmission rod and the rotating shaft are provided with slides, and one side is fixedly provided with a lifting seat and fixedly connected to the winding machine.
[0014] Preferably, the bidirectional transmission rod is a ball screw, with the connecting segments rotating in opposite directions and connected to the rotary sleeve via transmission.
[0015] Preferably, the side of the rotating shaft is provided with a sliding groove, which is slidably connected to the support plate inside the rotating frame.
[0016] Preferably, the outer side of the rotary sleeve has an annular groove, which is rotatably connected to the convex ring on the inner side of the rotary sleeve.
[0017] Preferably, the rolling part and the side of the rolling groove roll against each other, forming a defined axial positional relationship.
[0018] Preferably, the rolling section and the rolling groove are conical ring structures.
[0019] The beneficial effects of this utility model are:
[0020] 1. By setting a rolling mechanism on one side of the roller, the two sides of the woven bag are concave, thereby limiting the middle area of the woven bag body and preventing skewing during the conveying process from affecting the quality after winding.
[0021] 2.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0031] A plastic woven bag production winding device is provided for maintaining a fixed path for conveying woven bags for winding operations. By setting a rolling mechanism in the adjacent area of the side of the roller 11, the woven bag is squeezed to form a local V-shaped mechanism by using the V-shaped slope between the rolling groove 2212 and the rolling part 2121, thereby blocking the middle area of the woven bag and preventing it from tilting to one side. Then, it forms a clamp near the tail of the woven bag, keeping the woven bag winding cylinder taut and preventing slack, which is convenient for subsequent fixing and storage.
[0032] In some embodiments, the specific structure of the plastic woven bag production winding device is as follows: Figure 1-4 The diagram shows a winding machine 1 and its internally installed winding roller 11 and rolling mechanism 2;
[0033] The rolling mechanism 2 includes a bidirectional transmission rod 21 and a rotating shaft 22, located near the feed side of the roller 11;
[0034] Among them, the bidirectional transmission rod 21 is preferably a ball screw, including a left-hand section and a right-hand section, distributed at both ends;
[0035] The rotating shaft 22 is located directly below the bidirectional transmission rod 21, and is parallel to it. A sliding groove 2201 is provided on one side.
[0036] Furthermore, a rotating sleeve 211 for transmission engagement is installed on the outer side of the bidirectional transmission rod 21, and a rotating sleeve 212 is rotatably installed on the outer side of the rotating sleeve 211.
[0037] A rotating frame 221 is fitted on the outer side of the slide block 23, and a support plate 2211 extends out from the inner side of the rotating frame 221 and is slidably installed inside the slide groove 2201.
[0038] Furthermore, the outer side of the rotating sleeve 212 has an integral arched structure, which is preferably a conical rolling part 2121;
[0039] The outer side of the rotating frame 221 is provided with a recessed groove, and the groove structure is preferably a conical rolling groove 2212;
[0040] It should be noted that the rolling part 2121 is connected to the rolling groove 2212, and the slopes of the two roll in contact with each other. When the woven bag is conveyed through, it is squeezed and slightly deformed, thereby fixing its conveying path.
[0041] like Figure 1 and Figure 2 As shown, the rolling mechanism 2 also includes a slide 23, which is installed at both ends of the bidirectional transmission rod 21 and the rotating shaft 22;
[0042] Among them, the upper end of the slide 23 extends outward, and 231 is fixedly installed below the protruding plate;
[0043] Furthermore, the fixed end of 231 is connected to the top of the frame of the winding machine 1.
[0044] like Figure 3 and Figure 4 As shown, the inner side of the rotating sleeve 212 has an integral protruding ring 2122, which is rotatably installed inside the annular groove 21101 opened on the outer side of the rotating sleeve 211.
[0045] It is understandable that the transmission connection between the swivel sleeve 211 and the bidirectional transmission rod 21, through the mating of the convex ring 2122 and the ring groove 21101, and the mating of the rolling part 2121 and the rolling groove 2212, can drive the rotating frame 221 to slide laterally when the swivel sleeve 211 slides laterally, and maintain the rotating state of the rotating sleeve 212 during the lateral sliding.
[0046] Some publicly available information describes the specific usage methods of plastic woven bag production winding devices as follows:
[0047] S1. When winding up the woven bag, first pass the first section of the woven bag through the channel between the rotating sleeve 212 and the rotating frame 221, and then connect it to the winding roller 11 for winding operation.
[0048] S2. The woven bag being transported between the rotating sleeve 212 and the rotating frame 221 has its main body on both sides being squeezed and recessed into the inside of the rolling groove 2212 by the rolling part 2121, thereby creating a fixed transport path by rolling.
[0049] S3. Start the bidirectional transmission rod 21 to drive the outer screw-on sleeve 211 to slide laterally. The ring groove 21101 limits the convex ring 2122 and the rolling groove 2212 limits the rolling part 2121, and transmits the power of the lateral sliding, thereby driving the rotating frame 221 to slide along. Then, by using the opposite rotation directions at both ends of the bidirectional transmission rod 21, the distance between adjacent screw-on sleeves 211 is controlled, which can adapt to woven bags of different widths.
[0050] S4. When the roller 11 winds up the woven bag to form a winding drum to a predetermined thickness, the cut-off tail of the woven bag is clamped and fixed by the rolling part 2121 and the rolling groove 2212, thereby maintaining tension and preventing the winding drum from loosening, which facilitates the fixing of the woven bag on the outer ring of the winding drum and subsequent storage and use.
