Abstract
Description
Technical Field
[0001] This application relates to the field of bag-making machines, and particularly to a winding structure of an intelligent bag-making machine. Background Art
[0002] When dealing with waste plastics, the waste plastics are usually collected and pre-treated first, and then the raw materials made from the waste plastics are reprocessed to make new plastic products, so as to realize the recycling of resources, achieve beneficial effects such as saving resources and reducing the cost of garbage disposal. And preparing the raw materials made from waste plastics into packaging bags of various sizes by a bag-making machine is one of the effective ways to realize the reuse of waste plastics.
[0003] Currently, the plastic bags produced by a bag-making machine are usually wound by a corresponding winding structure. For example, in a patent named "A Bag-making Machine" with the publication number CN11700566B, the existing winding structure generally includes a winding roller, a motor, and a bracket for installing the winding roller. During the winding process, the motor drives the winding roller to rotate around its own axis on the bracket, thereby realizing the winding of the plastic bags produced by the bag-making machine.
[0004] However, when using this winding structure to wind the plastic bags produced by the bag-making machine, when the number of plastic bags wound on the winding roller reaches a certain amount, it is necessary to replace the winding roller. And during the replacement process, since the subsequent produced plastic bags cannot be wound, the operation of the bag-making machine often needs to be stopped until the new winding roller is replaced and then the bag-making machine can be started again. And during the shutdown process, the production of plastic bags will stop increasing, thus reducing the bag-making efficiency of the bag-making machine. Content of the Utility Model
[0005] In order to improve the winding efficiency of the bag-making machine, this application provides a winding structure of an intelligent bag-making machine, and adopts the following technical scheme:
[0006] It includes a workbench connected to the discharging end of the intelligent bag-making machine. A winding assembly is arranged on the workbench, and it is characterized in that: the winding assembly includes a rotating frame, a first driving member, a mounting seat, and a winding unit. The mounting seat is arranged on the workbench, the rotating frame is arranged on the mounting seat, the winding unit is arranged on the rotating frame, and there are at least two winding units. The winding unit is used for winding the bag bodies manufactured by the intelligent bag-making machine. The first driving member is arranged on the workbench, and the first driving member is used for driving the rotating frame to rotate on the mounting seat to realize the replacement between the winding units.
[0007] Preferably, the rotating frame includes a rotating shaft and two rotating plates. The rotating shaft is arranged on the mounting seat and can be driven by a first driving member to rotate around its own axis on the mounting seat. The two rotating plates are respectively fixedly installed on the rotating shaft and are located at both ends of the rotating shaft in the length direction. Both winding units are installed between the two rotating plates. When the rotating shaft rotates around its own axis, the two winding units rotate around the axis of the rotating shaft.
[0008] Preferably, a driven wheel is arranged at one end of the rotating shaft close to the first driving member, and a driving wheel is arranged on the first driving member. The driving wheel is used to drive the driven wheel to rotate around its own axis.
[0009] Preferably, the winding unit includes a driving centering member, a driven centering member, a second driving member and a core shaft. The driving centering member and the driven centering member are respectively located on the two rotating plates and are arranged oppositely. The core shaft is located between the driving centering member and the driven centering member. One end of the core shaft can be coaxially abutted against the driving centering member, and the other end of the core shaft can be coaxially abutted against the driven centering member. The second driving member is installed on the rotating plate provided with the driving centering member. The second driving member is used to drive the driving centering member to rotate around the axis of the core shaft as the rotation axis; when the driving centering member rotates, the core shaft and the driven centering member located between the driving centering member and the driven centering member rotate together with the driving centering member.
[0010] Preferably, the driving centering member includes a first fixing rod, a first movable rod, a first tapered cylinder and a first spring. One end of the first fixing rod is installed and connected to one of the rotating plates. A transmission part is arranged at one end of the first fixing rod close to the rotating plate. The second driving member drives the first fixing rod to rotate around its own axis on the rotating plate through the transmission part. The other end of the first fixing rod away from the rotating plate is sleeved on the first movable rod. The other end of the first movable rod away from the first fixing rod is inserted and matched with the larger-diameter end of the first tapered cylinder. The first spring is located in the first fixing rod. One end of the first spring abuts against the rotating plate, and the other end of the first spring abuts against one end of the first movable rod located in the first fixing rod. When the first fixing rod rotates around its own axis on the rotating plate, the first movable rod and the first tapered cylinder both rotate together with the first fixing rod.
[0011] Preferably, the driven centering member includes a second fixing rod, a second movable rod, a second tapered cylinder and a second spring. One end of the second fixing rod is installed on the rotating plate without the first fixing rod. The other end of the second fixing rod is sleeved on the second movable rod.

[0013] In summary, compared with the prior art, the advantages of the present application are as follows:
[0014] 1. By providing a rotating frame and a first driving member capable of driving the rotating frame to rotate, the two winding units on the rotating frame can be replaced with each other. The winding unit includes a mandrel for winding plastic bags and an active centering member and a driven centering member for realizing detachable connection with the mandrel. This enables, after one winding unit finishes winding, the mandrel of the other winding unit to wind the plastic bags by driving the rotating frame to rotate, and the mandrel that has finished winding can be removed from the active centering member and the driven centering member, and then a new mandrel can be replaced. During the process of replacing the mandrel that has finished winding, since there is always another mandrel winding the plastic bags, the bag making machine does not need to stop when replacing the mandrel that has finished winding, achieving the effect of improving the bag making efficiency of the bag making machine.
[0015] 2. By providing a first spring in the active centering member and a second spring in the driven centering member, the distance between the first conical cylinder and the second conical cylinder can be adjusted, and thus it can be applicable to mandrels of different lengths and sizes, and can be applicable to winding plastic bags of different sizes, achieving the effect of expanding the applicable range.

Detailed implementation mode
[0022] The following further elaborates on this application in conjunction with the attached Figures 1-5 drawings for a more detailed description.
[0023] Embodiment
[0024] An embodiment of this application discloses a winding structure of an intelligent bag-making machine. Referring to Figure 1 and Figure 2 , it includes a workbench 1 and a winding assembly 2 arranged on the workbench. The workbench 1 can be connected to the discharge end of the intelligent bag-making machine, and the winding assembly 2 is used to wind the plastic bags made by the intelligent bag-making machine.
[0025] The winding assembly 2 includes a rotating frame 3, a first driving member 4, a mounting seat 5, and a winding unit 6. Among them, the mounting seat 5 is arranged on the workbench 1, and the rotating frame 3 includes a rotating shaft 7 and two rotating plates 8 respectively fixed at both ends in the length direction of the rotating shaft 7. The rotating shaft 7 is installed on the mounting seat 5, and a driven wheel 9 is arranged at one end. The first driving member 4 is installed on the workbench 1. The first driving member 4 is a driving motor, and a driving wheel 10 is arranged on the output shaft of the first driving member 4. The driven wheel 9 and the driving wheel 10 are a pair of gears that can cooperate with each other. This enables the rotating shaft 7 to rotate around its own axis on the mounting seat 5 when the first driving member 4 is started, thereby driving the two rotating plates 8 to rotate together with the rotating shaft 7.
[0026] Referring to Figure 3 , Figure 4 and Figure 5 , there are two groups of winding units 6, which are symmetrically distributed on both sides of the rotating shaft 7 with the axis of the rotating shaft 7 as the symmetry axis. The winding unit 6 includes a driving centering member 11, a driven centering member 12, a second driving member 13, and a core shaft 14 for winding plastic bags. Among them, the driving centering member 11 and the driven centering member 12 are respectively installed on the opposite sides of the two rotating plates 8 and are coaxial. The driving centering member 11 and the driven centering member 12 respectively abut against both ends of the core shaft 14, and the driving centering member 11 can rotate around its own axis under the action of the second driving member 13 to drive the core shaft 14 to rotate so as to realize the winding of plastic bags.
[0027] The active centering member 11 includes a first fixed rod 15, a first movable rod 16, a first tapered cylinder 17, and a first spring 18. One end of the first fixed rod 15 is mounted on one of the rotating plates 8, and its cross-section is circular, and it can rotate around its own axis on the rotating plate 8. The other end of the first fixed rod 15 is sleeved on the first movable rod 16, and its cross-section is rectangular. The first movable rod 16 is a rectangular rod, and the end far from the first fixed rod 15 is connected to the first tapered cylinder 17 by means of plug-in fit. At a position where the first fixed rod 15 is close to the inner side of the rotating plate 8, a transmission part 19 is provided. In the embodiment of the present application, the transmission part 19 is a transmission tooth provided on the outer wall of the first fixed rod 15, and the second driving member 13 is mounted on the rotating plate 8 where the first fixed rod 15 is installed. A transmission gear that can be adapted to the transmission part 19 is provided on the output shaft of the second driving member 13. When the second driving member 13 is started, the first fixed rod 15 rotates around its own axis on the rotating plate 8. Since the cross-section of the part of the first fixed rod 15 sleeved on the first movable rod 16 is rectangular, and the first movable rod 16 is a rectangular rod, when the first fixed rod 15 rotates relative to its own axis on the rotating plate 8, the first movable rod 16 and the first tapered cylinder 17 both rotate together with the first fixed rod 15.
[0028] It should be noted that a nut is installed at the end of the first fixed rod 15 after passing through the rotating plate 8. The nut only plays a limiting role and does not affect the rotation of the first fixed rod 15 on the rotating plate 8.
[0029] The first spring 18 is located inside the first fixed rod 15. One end of the first spring 18 is connected to the side surface of the rotating plate 8 where the first fixed rod 15 is installed, and the other end of the first spring 18 abuts against the end of the first movable rod 16 located inside the first fixed rod 15, which enables the first tapered cylinder 17 to always abut against one end of the mandrel 14.
[0030] The driven intermediate member 12 includes a second fixed rod 20, a second movable rod 21, a second conical cylinder 22, and a second spring 23. The second fixed rod 20 is disposed on the other end block rotating plate 8 and is opposite to the first fixed rod 15. One end of the second fixed rod 20 is sleeved on the second movable rod 21. The end of the second movable rod 21 away from the second fixed rod 20 is inserted and matched with the second conical cylinder 22. It is worth mentioning that the cross-section at the position where the second movable rod 21 is inserted into the second conical cylinder 22 is circular, which enables the second conical cylinder 22 to rotate relative to the second movable rod 21. The second spring 23 is located inside the second fixed rod 20, and one end of the second spring 23 abuts against the second movable rod 21, which enables the second conical cylinder 22 on the second movable rod 21 to always abut against the end of the mandrel 14 away from the first conical cylinder 17. At the same time, this also enables the first conical cylinder 17 and the second conical cylinder 22 to be applicable to mandrels 14 of different lengths by means of the compression amounts of the first spring 18 and the second spring 23.
[0031] Further, anti-slip layers 24 are coated on the outer walls of the first conical cylinder 17 and the second conical cylinder 22, so that when the first conical cylinder 17 or the second conical cylinder 22 abuts against both ends of the mandrel 14 respectively, they will not easily slide relative to the mandrel 14.
[0032] It is worth mentioning that the mandrel 14 includes a shaft body and an adhesive layer provided on the shaft body. Among them, the shaft body is made of cardboard, and the adhesive layer is composed of glue smeared on the outer wall of the shaft body. This enables the plastic bag to be adhered to the mandrel 14 by smearing glue on the outer wall of the mandrel 14 when the mandrel 14 is required to wind up the plastic bag, so that the plastic bag can be wound up following the rotation of the mandrel 14.
[0033] The implementation principle of the embodiment of the present application is as follows: First, the two mandrels 14 are respectively installed between the first conical cylinder 17 and the second conical cylinder 22 on the two winding units 6, so that the first conical cylinder 17, the second conical cylinder 22, and the mandrel 14 are in a coaxial state. Then, the mandrel 14 near the bag making machine winds up the plastic bags produced by the bag making machine. During the winding process, the second driving member 13 is in a starting state, so that the first conical cylinder 17 can drive the mandrel 14 and the second conical cylinder 22 to rotate together around the axis of the mandrel 14.
[0034] When the winding of the current mandrel 14 is about to be completed, first apply glue to the outer wall of another mandrel 14, and then start the first driving member 4 to make the rotating shaft 7 start to rotate around its own axis, so that the other mandrel 14 replaces the position of the mandrel 14 that has wound the plastic bag. During the rotation of the rotating shaft 7, the plastic bag is still wound by the previous mandrel 14. Then start the second driving member 13 for driving the other mandrel 14 to rotate. Subsequently, by manually pressing the plastic bag, the plastic bag between the two mandrels 14 is brought into contact with the mandrel 14 after the replacement of the position, and the plastic bag between the two mandrels 14 is cut manually. Finally, the mandrel 14 that has completed winding can be removed from between the first conical cylinder 17 and the second conical cylinder 22 and a new mandrel 14 can be replaced (at this time, the second driving member 13 for driving this mandrel 14 to rotate is in a stopped state).
[0035] When the winding of the second mandrel 14 is about to be completed, first apply glue to the newly installed mandrel 14 subsequently, and then make the first driving member 4 start again to drive the rotating shaft to rotate in the reverse direction. Subsequently, again by manually pressing, the plastic bag between the two mandrels 14 is brought into contact with the unwound mandrel 14. Then start the second driving member 13 for driving the newly installed mandrel 14 to rotate. Finally, the plastic bag between the two mandrels 14 is cut so that the newly installed mandrel 14 can wind the plastic bag, and the second mandrel 14 that has completed winding is then removed and replaced by the staff.
[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
