Therefore, features defined as "first", "second", and "third" can explicitly or implicitly include one or more of these features. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration, not limitation, to facilitate a thorough understanding of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present invention with unnecessary detail.

[0026] like Figures 1 to 4 As shown, a plastic bag winding device of an embodiment of the present invention includes a bracket 10, a winding assembly 20 and a driving member 30. The winding assembly 20 includes a rotating rod 21, a reel 22 and a pressing strip 23. The rotating rod 21 is rotatably connected to the bracket 10 at one end close to the bracket 10, and the other end extends horizontally in a direction away from the bracket 10. The reel 22 is detachably mounted on the rotating rod 21. The reel 22 is provided with a storage cavity 21a extending along its length direction. The pressing strip 23 can be raised and lowered in the storage cavity 21a to press the head end of the plastic bag. The driving member 30 is mounted on the bracket 10 and is suitable for driving the rotating rod 21 to rotate to drive the reel 22 to achieve winding of the packaging bag 60.

[0027] The plastic bag reeling device based on the above technical features installs the reel 22 on the rotating rod 21 and drives the pressing bar 23 to rise from the storage chamber 21a. Then, the head end of the plastic bag is placed on the surface of the reel 22. The pressing bar 23 is then driven down and retracted into the storage chamber 21a to press the head end of the plastic bag placed on the surface of the reel 22. Finally, the driving member 30 drives the rotating rod 21 to rotate, thereby driving the reel 22 to automatically reel the packaging bag 60. In other words, the plastic bag reeling device uses the pressing bar 23 to press the head end of the plastic bag, so that when the driving member 30 drives the rotating rod 21 to rotate to drive the reel 22 to reel, the head end of the plastic bag is ensured to be firmly pressed against the reel 22, avoiding the problem of being unable to reel, thereby improving the efficiency and effect of plastic bag reeling.

[0028] In one possible embodiment, the device further includes a drive motor 24, one end of the storage chamber 21a is connected to a stepped groove, and the drive motor 24 is installed in the stepped groove. The end of the compression strip 23 near the stepped groove extends with a connecting portion extending toward the stepped groove. The connecting portion is located above the drive motor 24, and the output end of the drive motor 24 is connected to the connecting portion, which is suitable for driving the compression strip 23 to rise and fall. In other words, before the plastic bag is rolled, the head end of the plastic bag needs to be compressed to avoid the problem of being unable to be rolled due to poor clamping of the plastic bag. To this end, in this embodiment, the drive motor 24 installed in the stepped groove is used to drive the compression strip 23 to extend out of the storage chamber 21a, and then the head end of the plastic bag is placed under the compression strip 23. Then, the drive motor 24 is controlled to reverse so that the compression strip 23 compresses the head end of the plastic bag, thereby achieving compression of the plastic bag and ensuring a better subsequent rolling effect of the plastic bag.

[0029] In one possible embodiment, when the compression strip 23 is retracted into the storage cavity 21a, the upper surface of the compression strip 23 is flush with the surface of the reel 22. In this way, after the compression strip 23 compresses the head end of the plastic bag and is retracted into the storage cavity 21a, the compression strip 23 does not protrude from the reel 22, ensuring that wrinkles are not generated in the subsequent roll film.

[0030] In a possible embodiment, it also includes a first end plate and a second end plate connected to the rotating rod 21, and the second end plate can move along the length direction of the rotating rod 21 to adjust the distance between the first end plate and the second end plate, and the first end plate is connected to one end of the reel 22 close to the bracket 10, and the second end plate is connected to the other end of the reel 22.

[0031] In one possible embodiment, the first end plate and the second end plate are both provided with a first mounting hole, and the end surfaces at both ends of the reel 22 are provided with a second mounting hole adapted to the first mounting hole. In this way, after the reel 22 is inserted into the rotating rod 21, the first end plate abuts against one end surface of the reel 22, at which time the second mounting hole on the reel 22 and the first mounting hole on the first end plate are aligned, and then bolts are sequentially passed through the second mounting hole and the first mounting hole to fix one end of the reel 22, and then the second end plate is inserted into the rotating rod 21 and abuts against the end of the reel 22 away from the bracket 10, at which time the first mounting hole on the second end surface is aligned with the second mounting hole on the end surface of the reel 22, and then bolts are sequentially passed through the second mounting hole and the first mounting hole to fix the other end of the reel 22, thereby completing the fixed installation of the reel 22, so that the reel 22 of the rolled plastic bag can be quickly removed from the rotating rod 21 later.

[0032] In a possible embodiment, a transmission assembly 70 is further included, which includes a driving wheel 71, a driven wheel 72 and a transmission belt. The driving wheel 71 is installed at the output end of the driving member 30, and the driven wheel 72 is installed at one end of the rotating rod 21 that passes through the bracket 10, and a transmission belt is connected between the driven wheel 72 and the driving wheel 71.

[0033] For example, when the packaging bag 60 is to be rolled up, the driving member 30 is used to drive the driving wheel 71 to rotate. Since a transmission belt is connected between the driving wheel 71 and the driven wheel 72, the driven wheel 72 is installed at one end of the rotating rod 21 passing through the bracket 10, so that the rotating rod 21 is driven to rotate, thereby driving the reel 22 connected to the rotating rod 21 to rotate to realize automatic rolling of the packaging bag 60. When the reel 22 has rolled up enough packaging bags 60, the driving member 30 stops working, so that the reel 22 stops running. At this time, the reel 22 and the rolled packaging bag 60 are removed from the rotating rod 21, and then a new reel 22 is installed to roll up the packaging bag 60. The structure is simple and the operation is convenient.

[0034] In one possible embodiment, a shaft sleeve is further included, which is embedded in the bracket 10, and the rotating rod 21 passes through the shaft sleeve, so that the rotating rod 21 is rotatably connected to the bracket 10. In this way, by embedding the shaft sleeve in the bracket 10 and passing the end of the rotating rod 21 closer to the bracket 10 through the shaft sleeve, the rotating rod 21 can rotate relative to the bracket 10, thereby driving the reel 22 sleeved on the rotating rod 21 to rotate, thereby achieving automatic reeling of the produced packaging bags 60, with a simple structure and convenient operation.

[0035] In one possible embodiment, the stand 10 further includes a base 40, to which the lower end is connected. A plurality of foot pads 50 are provided on the lower surface of the base 40 for support. Thus, the base 40 is supported by the plurality of foot pads 50, so that the stand 10 can be placed more stably and will not fall over or become unstable during use.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
