Abstract
Description
Technical Field
[0001] This utility model belongs to the field of packaging bag production technology, and in particular relates to a food plastic packaging bag winding device. Background Technology
[0002] As the basic carrier for food storage, transportation and sales, food plastic packaging bags generally need to be rolled into rolls during production to meet the needs of large-scale storage, long-distance transportation and subsequent cutting and processing.
[0003] Currently, existing winding devices are susceptible to factors such as tension fluctuations and equipment vibrations during operation, which can cause axial displacement during winding, resulting in uneven winding, misalignment of end faces, and other problems. This may lead to defects in the product appearance or positioning deviations during subsequent slitting, thus reducing product quality.
[0004] To address the aforementioned problems, this application proposes a food plastic packaging bag winding device. Utility Model Content
[0005] The purpose of this invention is to provide a food plastic packaging bag winding device, which solves the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to a food plastic packaging bag winding device, comprising a horizontal base and a winding roller and a guide roller disposed above it, and further comprising:
[0008] Two correction sleeves are symmetrically slidably sleeved at both ends of the guide roller. Each correction sleeve includes a cylindrical section and a frustum section, and the outer wall of the frustum section of the correction sleeve is provided with a threaded structure for guiding the packaging bag to reset.
[0009] Two sliding plates are rotatably connected to the cylindrical sections of two correction sleeves, and the lower ends of the two sliding plates are threadedly connected to the same bidirectional screw.
[0010] Furthermore, two vertical plates are fixedly mounted on the top surface of the horizontal base, and a rotating shaft is rotatably mounted between the two vertical plates. The guide roller is fixed on the outer wall of the rotating shaft, and the bidirectional screw is rotatably mounted between the two vertical plates. A motor is fixedly mounted on the outside of one of the two vertical plates, and the output shaft of the motor is fixedly connected to the bidirectional screw.
[0011] Furthermore, a guide rod is fixed between the two vertical plates, and the guide rod is slidably connected to the sliding plate.
[0012] Furthermore, the correction sleeve is fixedly provided with a fixed plate that is penetrated by the rotating shaft, and the fixed plate is provided with a smooth groove, and the outer wall of the rotating shaft is fixedly provided with a guide rail that is slidably connected to the smooth groove.
[0013] Furthermore, the threaded structures on the outer walls of the two correction sleeves have opposite helical directions.
[0014] Furthermore, the alignment sleeve is made of wear-resistant engineering plastic with a low coefficient of friction.
[0015] Furthermore, two vertical plates are fixedly mounted on the top surface of the horizontal base, and the winding roller is rotatably installed between the vertical plates.
[0016] This utility model has the following beneficial effects:
[0017] This utility model uses a threaded structure and a truncated cone section of the correction sleeve to form a threaded inclined surface structure. As the packaging bag moves forward, it drives the guide roller to rotate. Once the packaging bag deviates, the threaded inclined surface structure will generate a force on the packaging bag to guide it towards the center, thus automatically correcting the deviated packaging bag.
[0018] This invention allows two sliding plates to move in opposite directions by rotating a bidirectional screw, which in turn moves the correction sleeve horizontally, thus adjusting the spacing between the correction sleeves and making the device suitable for packaging bags of different widths.
[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] 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.
[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are 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.
[0029] Please see Figures 1 to 4 As shown, this utility model is a food plastic packaging bag winding device, including a horizontal base 1 and a winding roller 2 and a guide roller 3 arranged above it, and also includes: two correction sleeves 4, which are symmetrically slidably sleeved on both ends of the guide roller 3. The correction sleeve 4 includes a cylindrical section and a frustum section, and the outer wall of the frustum section of the correction sleeve 4 is provided with a threaded structure 401 for guiding the packaging bag to reset. Two sliding plates 5 are rotatably connected to the cylindrical sections of the two correction sleeves 4 respectively. The lower ends of the two sliding plates 5 are threadedly connected to the same bidirectional screw 6.
[0030] This embodiment provides a food plastic packaging bag winding device. The larger end of the frustum section of the correction sleeve 4 is fixedly connected to the cylindrical section, and the smaller end of the frustum section faces the center of the guide roller 3. When the packaging bag deviates, the frustum section of the correction sleeve 4 can guide the packaging bag, causing it to move closer to the center and return to its original position, thus correcting the deviation. The threaded structure 401 further guides the packaging bag to reset. When the bidirectional screw 6 rotates, it drives the two sliding plates 5 to move in opposite directions, adjusting the distance between the two sliding plates 5. This device is suitable for packaging bags of different widths.
[0031] Two vertical plates 302 are fixedly mounted on the top surface of the horizontal base 1, and a rotating shaft 301 is rotatably mounted between the two vertical plates 302. The guide roller 3 is fixedly mounted on the outer wall of the rotating shaft 301. The bidirectional screw 6 is rotatably mounted between the two vertical plates 302. A motor 601 is fixedly mounted on the outside of one of the two vertical plates 302, and the output shaft of the motor 601 is fixedly connected to the bidirectional screw 6. The motor 601 is used to drive the bidirectional screw 6 to rotate, thereby driving the sliding plate 5 to move and realize the adjustment of the spacing of the correction sleeve 4.
[0032] Among them, a guide rod 7 is fixed between the two vertical plates 302, and the guide rod 7 is slidably connected to the sliding plate 5. The guide rod ensures that the sliding plate 5 maintains linear motion when it moves, thereby improving stability.
[0033] The correction sleeve 4 is fixedly provided with a fixed plate 8 that is penetrated by the rotating shaft 301, and the fixed plate 8 is provided with a smooth groove 801. The outer wall of the rotating shaft 301 is fixedly provided with a guide rail 3011 that is slidably connected to the smooth groove 801. The cooperation between the guide rail 3011 and the smooth groove 801 ensures the stability of the correction sleeve 4 when it moves, and also ensures that the correction sleeve 4 rotates synchronously with the guide roller 3.
[0034] Among them, the threaded structures 401 on the outer walls of the two correction sleeves 4 have opposite spiral directions. When the packaging bag deviates to one side, the threaded structure 401 of the corresponding correction sleeve 4 guides it to move towards the center, thereby achieving bidirectional correction.
[0035] Among them, the correction sleeve 4 is made of wear-resistant and low-friction engineering plastic. The material of the correction sleeve 4 is polyoxymethylene or polyamide. The surface of the low-friction engineering plastic is very smooth, and the friction generated when it comes into contact with the packaging bag is controllable and gentle. This can ensure that the correction sleeve 4 can guide the packaging bag to return to its original position, and also avoid tearing the packaging bag or leaving scratches on its surface.
[0036] The horizontal base 1 has two vertical plates 201 fixed on its top surface, and the winding roller 2 is rotatably installed between the vertical plates 201.
[0037] It is understood that when the packaging bag shifts, the corrective sleeve 4 guides the packaging bag to return to its original position. At the same time, the distance between the corrective sleeves 4 can be adjusted so that the device can be adapted to packaging bags of different widths.
[0038] A specific application of the operation process in this embodiment is as follows: Before the packaging bag is rolled up, the user should adjust the spacing of the correction sleeve 4 according to the width of the packaging bag. When adjusting, the motor 601 is started to drive the bidirectional screw 6 to rotate, which further drives the two sliding plates 5 to move axially along the guide rod 7 to adjust the spacing of the correction sleeve 4.
[0039] During the winding process, if the packaging bag deviates, when it passes the guide roller 3, the threaded structure 401 of the outer wall of the contact correction sleeve 4 will generate a radial thrust on the packaging bag, driving the packaging bag to reset towards the center, thus achieving automatic correction.
