Technical Field
[0001] This utility model relates to the field of garbage bag rolling technology, and in particular to a garbage bag production rolling device. Background Technology
[0002] In the garbage bag production process, the winding stage is crucial, as its quality directly affects subsequent packaging, transportation, and user experience. Current garbage bag winding devices on the market have several limitations. Firstly, most devices can only accommodate a single size of garbage bag. When producing different sizes, frequent changes to the winding components are required, which is cumbersome and time-consuming, significantly reducing production efficiency and increasing costs. Secondly, the ends of the garbage bag are prone to unevenness during winding, resulting in an inconsistent appearance of the rolled garbage bag. This not only affects the product's aesthetics but may also cause problems during subsequent packaging and use, such as difficulty in packaging or the garbage bag easily unraveling during use. Therefore, it is necessary to develop a garbage bag production winding device that addresses these shortcomings. Utility Model Content
[0003] The purpose of this invention is to provide a garbage bag production and winding device. By coordinating the adjustment component and the drive component, it can quickly adapt to the winding requirements of garbage bags of different specifications. Moreover, during the winding process, the sides of the garbage bag are less likely to wrinkle or break, which effectively improves production efficiency and product quality.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] This utility model discloses a garbage bag production and winding device, including a frame. Upright plates are provided on both sides of the upper end of the frame, and the upright plates are vertically fixed to the upper surface of the frame. A set of adjusting components is horizontally installed on the inner side of the upper end of each of the upright plates. A winding roller for winding garbage bags is detachably installed between the two adjusting components. The two ends of the winding roller are mounted on the adjusting components. An electric telescopic rod is provided on the outer side of each upright plate, and the electric telescopic rod is fixedly connected to the adjacent adjusting component. The adjusting component moves relative to the adjusting component under the drive of the electric telescopic rod to clamp or release the winding roller. A driving component is provided at one of the adjusting components, and the driving component is located between the upright plate and the adjacent adjusting component. The driving component drives the adjusting component to rotate, thereby causing the winding roller to rotate.
[0006] Preferably, the adjustment assembly includes a fixed shaft, a rotating disk, a limiting disk, and a connecting rod. The fixed shaft is fixedly installed on the inner side of the upright plate and is horizontally arranged. The rotating disk is fitted on the outer circumference of the fixed shaft and is rotatably connected to the fixed shaft. A limiting disk is provided on the side of the rotating disk away from the upright plate, and the limiting disk is slidably connected to the rotating disk. A connecting rod is provided on the side of the limiting disk near the rotating disk. One end of the connecting rod is fixedly installed on the telescopic end of the electric telescopic rod, and the other end of the connecting rod passes through the fixed shaft and is rotatably connected to the limiting disk. The connecting rod is slidably connected to the fixed shaft.
[0007] Preferably, the drive assembly includes a motor, a drive pulley, a driven pulley, and a belt. The motor is fixed on the frame, the drive pulley is fixed on the output shaft of the motor, the driven pulley is rotatably mounted on the fixed shaft and located between the rotating disk and the upright plate, the rotating disk and the driven pulley are fixedly connected together by bolts, and the drive pulley and the driven pulley are connected by the belt drive.
[0008] Preferably, the take-up roller has clamping sections at both ends and a take-up section in the middle. The clamping sections have protrusions, which are square. The clamping sections are inserted into the limiting disk. The inner side of the limiting disk has a square groove that matches the protrusion. The axis of the limiting disk is consistent with the axis of the take-up roller. The two end faces of the take-up section abut against the inner side of the limiting disk.
[0009] Preferably, a rotating shaft is provided at the center of the limiting plate near the connecting rod. The rotating shaft extends out of the end face of the limiting plate and is integral with the limiting plate.

[0010] Preferably, the limiting disk has slide rods on both sides away from the rotating shaft, the slide rods are arranged parallel to the rotating shaft, and the rotating disk has guide posts on both sides corresponding to the slide rods. The slide rods are slidably installed in the guide posts. When the electric telescopic rod drives the limiting disk to slide forward, the slide rods on both sides move along the axial direction of the guide posts.
[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0012] This utility model relates to a garbage bag production and winding device. An electric telescopic rod drives the adjustment component to move relative to the winding roller, clamping or releasing it. Combined with the matching structure of the square protrusions and grooves on the limiting plate and the clamping section of the winding roller, different specifications of winding rollers can be quickly changed without cumbersome disassembly and component replacement. This significantly reduces downtime caused by product specification changes and greatly improves production efficiency. The limiting plate at the front of the adjustment component cooperates with the end of the winding roller to achieve stable positioning of both ends of the garbage bag, effectively preventing the ends of the garbage bag from shifting or misaligning during winding. Simultaneously, the sliding connection design between the limiting plate and the rotating plate, along with the guiding structure of the sliding rod and guide column, ensures that the limiting plate remains in contact with the ends of the garbage bag during winding, further guaranteeing the neatness of both ends of the rolled garbage bag, improving product appearance quality, and avoiding problems such as difficulty in subsequent packaging and easy unraveling during use caused by uneven ends.

[0018] The core of this utility model is to provide a garbage bag production and winding device. By adjusting the components and driving components working together, it can quickly adapt to the winding requirements of garbage bags of different specifications. Moreover, during the winding process, the sides of the garbage bags are less likely to wrinkle or break, which effectively improves production efficiency and product quality.

[0021] Refer to the attached diagram. Figure 1 This is a three-dimensional structural diagram of the garbage bag production and winding device of this utility model; Figure 2 This is a schematic diagram of the main sectional view of the garbage bag production and winding device of this utility model; Figure 3 An exploded view of the regulating and driving components.
[0022] In one specific implementation, such as Figures 1-3 As shown, a garbage bag production and winding device includes a frame 1. Vertical plates 2 are provided on both sides of the upper end of the frame 1, and the vertical plates 2 are vertically fixed to the upper surface of the frame 1. The vertical plates 2 and the frame 1 are connected by bolts to ensure a secure connection. A set of adjusting components 3 is horizontally installed on the inner side of the upper end of each of the two vertical plates 2. A winding roller 4 for winding garbage bags is detachably installed between the two adjusting components 3, with both ends of the winding roller 4 mounted on the adjusting components 3. An electric telescopic rod 5 is provided on the outer side of the vertical plate 2, and the electric telescopic rod 5 is fixedly connected to the adjacent adjusting component 3. The adjusting component 3 moves relative to the adjusting component 3 under the drive of the electric telescopic rod 5 to clamp or release the winding roller 4. A drive component 6 is provided at one of the adjusting components 3, and the drive component 6 is located between the vertical plate 2 and the adjacent adjusting component 3. The drive component 6 drives the adjusting component 3 to rotate, thereby driving the winding roller 4 to rotate.
[0023] In one specific implementation, such as Figures 1-3As shown, the adjusting assembly 3 includes a fixed shaft 31, a rotating disk 32, a limiting disk 33, and a connecting rod 34. The fixed shaft 31 is fixedly installed on the inner side of the upright plate 2, and the fixed shaft 31 is horizontally positioned. The rotating disk 32 is fitted onto the outer circumference of the fixed shaft 31 and is rotatably connected to the fixed shaft 31. A limiting disk 33 is provided on the side of the rotating disk 32 away from the upright plate 2, and the limiting disk 33 is slidably connected to the rotating disk 32. A connecting rod 34 is provided on the side of the limiting disk 33 near the rotating disk 32. One end of the connecting rod 34 is fixedly installed on the telescopic end of the electric telescopic rod 5, and the other end of the connecting rod 34 passes through the fixed shaft 31 and is rotatably connected to the limiting disk 33. The connecting rod 34 is slidably connected to the fixed shaft 31. The electric telescopic rod 5 extends and retracts, pushing the connecting rod 34, causing the limiting disk 33 to slide along the fixed shaft 31, thereby clamping or releasing the winding roller 4. The rotating disk 32 can rotate freely around the fixed shaft 31, providing a base for the rotation of the winding roller 4.
[0024] In one specific implementation, such as Figures 1-3 As shown, the drive assembly 6 includes a motor 61, a drive pulley 62, a driven pulley 63, and a belt 64. The motor 61 is fixed to the frame 1. Here, a variable frequency motor 61 is selected, which can adjust its speed in real time according to changes in the thickness, material, and winding diameter of the garbage bag to ensure stable winding tension. The drive pulley 62 is fixed to the output shaft of the motor 61. The driven pulley 63 is rotatably mounted on the fixed shaft 31 and located between the rotating disk 32 and the upright plate 2. The rotating disk 32 and the driven pulley 63 are fixedly connected by bolts. The drive pulley 62 and the driven pulley 63 are connected by a belt 64 to achieve the winding action of the garbage bag.
[0025] In one specific implementation, such as Figures 1-3 As shown, the take-up roller 4 has clamping sections 41 at both ends and a take-up section 42 in the middle. The clamping sections 41 have square protrusions 43. The clamping sections 41 are inserted into the limiting plate 33. The inner side of the limiting plate 33 has square grooves 332 that match the protrusions 43. The axis of the limiting plate 33 is consistent with the axis of the take-up roller 4. The two end faces of the take-up section 42 abut against the inner side of the limiting plate 33. The protrusions 43 of the clamping sections 41 and the grooves 332 of the limiting plate 33 cooperate to achieve circumferential positioning and self-locking, preventing relative sliding of the take-up roller 4 when it rotates. The limiting plate 33 limits the two ends of the take-up roller 4 to ensure that the edges of the garbage bag are neat when it is rolled up.
[0026] In one specific implementation, such as Figures 1-3As shown, a rotating shaft 331 is provided on the side of the limiting disc 33 near the connecting rod 34. The rotating shaft 331 extends out of the end face of the limiting disc 33 and is an integral structure with the limiting disc 33. The front end of the connecting rod 34 has a round hole, and the rotating shaft 331 is rotatably installed in the round hole of the connecting rod 34. When the connecting rod 34 moves under the drive of the electric telescopic rod 5, the rotating shaft 331 rotates in the round hole of the connecting rod 34, so that the limiting disc 33 can move axially and rotate with the rotating disc 32, adapting to the winding of garbage bags of different sizes.
[0027] In one specific implementation, such as Figures 1-3 As shown, sliding rods 333 are provided on both sides of the limiting disc 33, away from the rotating shaft 331. The sliding rods 333 are parallel to the rotating shaft 331. Guide posts 321 are provided on both sides of the rotating disc 32, corresponding to the sliding rods 333. The sliding rods 333 are slidably installed in the guide posts 321. When the electric telescopic rod 5 drives the limiting disc 33 to slide forward, the sliding rods 333 on both sides move along the axial direction of the guide posts 321. This ensures that the limiting disc 33 moves smoothly along the axial direction under the drive of the electric telescopic rod 5, and at the same time, it always fits the end face of the garbage bag during the winding process, ensuring that the winding edge is neat.
[0028] The operation process of this utility model garbage bag production and winding device is as follows: The electric telescopic rod 5 is activated, causing it to retract and move the adjusting components 3 on both sides outward, releasing installation space for the winding roller 4. A winding roller 4 of the corresponding size is selected according to the garbage bag specifications, with the width of the winding section 42 matching the unfolded width of the garbage bag. The clamping sections 41 at both ends of the winding roller 4 are aligned with the square grooves 332 of the limiting plate 33 and inserted between the adjusting components 3. The electric telescopic rod 5 is activated, causing it to extend and push the connecting rod 34 to move the limiting plate 33 inward until the inner surface of the limiting plate 33 is tightly abutted against the two end faces of the winding section 42, and simultaneously the square protrusion 43 fully engages with the groove 332, completing the fixing of the winding roller 4. The limiting plate 33 slides within the guide post 321 via the sliding rod 333, ensuring that the axis is aligned with the winding roller 4 during movement and avoiding eccentricity. Start motor 61. The output shaft of motor 61 drives the drive pulley 62 to rotate, which in turn drives the driven pulley 63 to rotate via belt 64. This, in turn, drives the rotating disk 32 and the limiting disk 33 to rotate synchronously. The winding roller 4, installed in the limiting disk 33, rotates accordingly. The front end of the garbage bag is fixed to the surface of the winding roller 4. As the winding roller 4 rotates, the garbage bag gradually wraps around the winding section 42. The limiting disk 33 always fits against both ends of the garbage bag to prevent the edges from unraveling or misaligning. If any abnormal situation such as garbage bag breakage occurs during the winding process, motor 61 should be stopped immediately. The problem should be checked and repaired before continuing winding. After winding is completed, the electric telescopic rod 5 retracts, the adjusting component 3 moves outward, and the limiting disk 33 separates from the winding roller 4, allowing the wound garbage bag roll to be quickly removed. If a different specification of winding roller 4 needs to be replaced, the above steps are repeated. No other parts need to be disassembled; only the winding roller 4 needs to be replaced.
[0029] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
[0030] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
