Description

Technical Field

[0001] This utility model belongs to the field of plastic bag production technology, specifically relating to a winding machine for plastic bag production. Background Technology

[0002] After the plastic bags are produced and processed, the finished products need to be rolled and cut. The plastic bags are wound into rolls in an orderly manner by the rolling equipment, and then precisely cut into rolls of specific specifications. These rolls are then packaged and stored, which facilitates warehousing management, saves space, and is also beneficial for subsequent transportation and use.

[0003] In the related technology (Chinese utility model patent with announcement number CN219173839U), a winding mechanism for producing rust-proof plastic bags is disclosed. During the winding process, the plastic bag is first pressed by the first pressure bar and the second pressure bar before being wound onto the outer end of the winding roller. On the one hand, this makes the plastic bag more neat and less prone to loosening. On the other hand, the first pressure bar and the second pressure bar play a certain cleaning role on the upper and lower surfaces of the plastic bag, filtering out large particulate impurities adsorbed on the surface of the plastic bag, making the wound plastic bag more flat and clean. The third pressure bar provides a secondary pressing effect on the wound plastic bag and a secondary impurity filtration effect on the outer surface of the plastic bag, thereby obtaining a wound plastic bag with neat edges and tight cleanliness.

[0004] In the plastic bag winding process, the finished product roll wound on the reel has a large self-weight, and existing technologies usually use an inclined slope guide platform to guide the material unloading. However, the guide platform that relies solely on the slope lacks a buffering and damping mechanism. When the roll rolls down the platform under the action of gravity, it is difficult to brake quickly due to inertia, and manual intervention is often required for positioning and calibration. This rigid unloading method without buffering not only increases the labor intensity of manual labor, but also easily causes packaging damage or reel deformation due to the impact of the roll, affecting product quality and production efficiency. Utility Model Content

[0005] To address the problems of existing inclined guide platforms that rely solely on slope for material feeding, lacking buffering and damping, and requiring manual positioning due to the inertia of the material rolls, which increases labor intensity and easily leads to packaging damage and roll deformation, affecting quality and efficiency, this utility model provides a winding machine for plastic bag production. By setting multiple sets of relatively rotating buffer blocks, a dynamic damping buffer system is constructed. During the feeding process of the finished material roll, multi-stage contact damping gradually reduces its motion inertia. This method utilizes the rotational friction of the buffer blocks to create continuous resistance, effectively counteracting the kinetic energy generated by the weight of the finished material roll, achieving precise control of the feeding speed and rapid braking. Stable feeding of the finished material roll can be completed without manual intervention, significantly improving the automation level and production efficiency of the winding machine's feeding process. The specific technical solution is as follows: A winding machine for producing plastic bags includes a winding machine body, comprising: connecting arms, guide brackets, damping components, a roll, and a finished product roll. Two connecting arms are provided, with one end of each arm vertically and fixedly installed on the front sidewall of the winding machine body. The guide brackets are fixedly installed on the other end of the connecting arms, and are arranged in a right-angled triangle, with the front sidewall forming the hypotenuse of the right-angled triangle. An arc-shaped placement groove is provided at the top of the guide bracket. Multiple sets of damping components are provided, each set positioned between two of the guide brackets. The roll is placed in the placement groove at the top of the guide bracket. The finished product roll is wound onto the roll.

[0006] In the above technical solution, the spacing between two adjacent sets of damping components is the same.

[0007] In the above technical solution, each damping component includes: a rotating rod, a mounting base, and a buffer block. The rotating rod is rotatably connected between the two guide brackets; the mounting base is fixedly mounted on the rotating rod; and the buffer block is fixedly mounted on the mounting base.

[0008] In the above technical solution, the cross-sectional shape of the buffer block is set as a right triangle, and the two acute angles of the buffer block are provided with rounded chamfer structures.

[0009] In the above technical solution, the damping assembly further includes: a torsion spring, a first connecting seat, and a second connecting seat. The torsion spring is sleeved on the rotating rod. The first connecting seat is fixedly installed on the rotating rod, and one end of the torsion spring is embedded in the first connecting seat. The second connecting seat is fixedly installed on the side wall of the guide bracket, and the rotating rod passes through the side wall of the second connecting seat and is rotatably connected to the side wall of the guide bracket. The other end of the torsion spring is embedded in the second connecting seat.

[0010] The above technical solution also includes an interception component, which includes an interception frame and an arc-shaped surface. The interception frame is installed on the front side wall of the guide bracket and is L-shaped. The arc-shaped surface is located at the right-angled side of the inner cavity of the interception frame and is circular.

[0011] The above technical solution also includes: a support frame and a support base, wherein one end of the support frame is fixedly installed on the side wall of the guide bracket on the right side; the support base is installed on the other end of the support frame, and an arc-shaped groove is provided at the top of the support base; The scroll is placed inside the support cavity.

[0012] The above technical solution also includes: a coupling sleeve and a first positioning pin, wherein the coupling sleeve is configured as a hollow sleeve structure, and the reel is inserted into one side of the coupling sleeve; the first positioning pin is threaded through the outer wall of the coupling sleeve and the reel in a vertical direction.

[0013] The above technical solution also includes: a motor frame, a motor, a drive shaft, and a second positioning pin. One end of the motor frame is fixedly installed on the side wall of the guide bracket on the right side; the motor is installed on the other end of the motor frame; one end of the drive shaft is connected to the output end of the motor, and the other end of the drive shaft is inserted into the other side of the coupling sleeve; the second positioning pin is threaded through the outer wall of the coupling sleeve and the drive shaft in the vertical direction.

[0014] In the above technical solution, the drive shaft, the connecting sleeve, and the reel are arranged with their axes collinear.

[0015] The advantages of this utility model for a plastic bag production winding machine compared with the prior art are as follows: I. Addressing the problems of existing inclined guide platforms that rely solely on slope for material feeding, lacking buffering and damping, and requiring manual positioning of the material rolls due to inertia, which increases labor intensity and easily leads to packaging damage and roll deformation, affecting quality and efficiency, this utility model constructs a dynamic damping buffer system by setting multiple sets of relatively rotating buffer blocks. During the feeding process of the finished material rolls, multi-stage contact damping gradually reduces their motion inertia. This method utilizes the rotational friction of the buffer blocks to form continuous resistance, effectively offsetting the kinetic energy generated by the finished material rolls due to their own weight, achieving precise control of feeding speed and rapid braking. Stable feeding of finished material rolls can be completed without manual intervention, significantly improving the automation level and production efficiency of the winding machine's feeding process, while avoiding material roll damage and positioning deviation problems caused by inertial impact. II. This utility model drives the buffer blocks to rotate through the rolling contact between the finished material roll and multiple sets of buffer blocks. After completing a single damping buffering cycle, the buffer blocks automatically reverse and reset with the help of the torsion spring. This mechanism allows the buffer blocks to enter the damping state of the next cycle without manual intervention, ensuring continuous buffering damping for the continuous feeding process of the finished material roll, forming an automated cyclic damping buffering system. This effectively improves the continuity and stability of the feeding process, reduces manual operation costs, and ensures the continuity of the damping function. Third, this utility model adds an interceptor frame and an arc-shaped surface to form a limiting and blocking mechanism. This mechanism accurately positions and intercepts the finished material roll after it has been damped by the buffer block. Through the synergistic effect of the interceptor frame and the arc-shaped surface, a closed-loop constraint space is formed, ensuring that the finished material roll is reliably limited and stored in the designated area of ​​the interceptor frame after the material unloading damping process is completed. This effectively prevents the finished material roll from falling due to inertia or other external forces, providing a stable guarantee for the subsequent centralized collection process and improving the integrity and reliability of the automated material collection process. In summary, this invention constructs a dynamic damping buffer system using multiple sets of relatively rotating buffer blocks to control the feeding speed of the finished material roll and brake it quickly, thereby improving automation and production efficiency and preventing damage to the material roll. The use of torsion springs enables the buffer blocks to automatically reverse and reset, ensuring continuous damping during continuous feeding and reducing labor costs. The limiting and blocking mechanism, composed of an interceptor frame and an arc-shaped surface, accurately intercepts and limits the finished material roll after damping and buffering, preventing it from falling and ensuring the integrity and reliability of the automated material receiving process.

[0017] The following are specific implementation cases and appendices. Figures 1 to 6 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0018] A plastic bag production winding machine includes a winding machine body 1, comprising: connecting arms 2, guide brackets 3, damping components, a roll 10, and finished product rolls 11. Two connecting arms 2 are provided, with one end of each arm vertically and fixedly installed on the front side wall of the winding machine body 1. The guide brackets 3 are fixedly installed on the other end of the connecting arms 2, and are arranged in a right-angled triangle, with the front side wall of the guide bracket 3 forming the hypotenuse of the right-angled triangle. An arc-shaped placement groove is provided at the top of the guide bracket 3. Multiple sets of damping components are provided, and these damping components are respectively positioned between the two guide brackets 3. The roll 10 is placed in the placement groove at the top of the guide bracket 3. The finished product rolls 11 are wound around the roll 10. This invention forms a dynamic damping buffer system by configuring multiple sets of relatively rotatable damping components. During the unloading process of the finished material roll 11, the rotational friction of the damping components generates continuous resistance. Through multi-stage contact damping, the motion inertia of the finished material roll 11 is gradually attenuated, effectively offsetting the kinetic energy generated by its own weight. This achieves precise control of the unloading speed and rapid braking, and the stable unloading of the finished material roll 11 can be completed without manual intervention. This significantly improves the automation level and production efficiency of the unloading process of the winding machine, while avoiding damage to the material roll and positioning deviation caused by inertial impact.

[0019] For specific main references Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the spacing between adjacent damping components is the same, thus ensuring that multiple damping components can form a continuous and equal damping effect on the finished material roll 11. Each damping component includes: a rotating rod 4, a mounting base 5, and a buffer block 6. The rotating rod 4 is rotatably connected between two guide brackets 3 via bearings. The mounting base 5 is fixedly installed on the rotating rod 4. The buffer block 6 is fixedly installed on the mounting base 5. The finished material roll 11 rolls and contacts the buffer block 6 during the falling process, thereby achieving multiple damping buffering of the finished material roll 11 by the buffer block 6. In addition, the cross-sectional shape of the buffer block 6 is set as a right-angled triangle, and the two acute angles of the buffer block 6 are provided with a rounded chamfer structure. The rounded chamfer structure can prevent the sharp buffer block 6 from causing scratches or other damage to the finished material roll 11 when it drives the buffer block 6 to rotate.

[0020] Main references Figure 3 , Figure 5 and Figure 6As shown, the damping assembly also includes: a torsion spring 7, a first connecting seat 8, and a second connecting seat 9. The torsion spring 7 is sleeved on the rotating rod 4; the first connecting seat 8 is fixedly installed on the rotating rod 4, and one end of the torsion spring 7 is embedded in the first connecting seat 8; the second connecting seat 9 is fixedly installed on the side wall of the guide bracket 3, and the rotating rod 4 passes through the side wall of the second connecting seat 9 and is rotatably connected to the side wall of the guide bracket 3 through a bearing. The other end of the torsion spring 7 is embedded in the second connecting seat 9, that is, the rotation of the rotating rod 4 will not affect the position of the second connecting seat 9, and the rotating rod 4 passes through the second connecting seat 9 without contacting the second connecting seat 9. After the spool 10 and the finished product roll 11 are lifted from the top placement slot of the guide bracket 3, the spool 10 rolls down along the inclined front side wall of the guide bracket 3. When rolling down, the finished product roll 11 on the outer wall of the spool 10 first contacts the buffer block 6 and drives it to rotate downwards, which drives the rotating rod 4, the first connecting seat 8 and the end of the torsion spring 7 to rotate synchronously, causing the torsion spring 7 to undergo torsional deformation. When the finished product roll 11 is separated from the buffer block 6, the elastic force of the torsion spring 7 drives the buffer block 6 to return to its original position. During the rolling down process of the spool 10, multiple sets of buffer blocks 6 achieve the buffering effect on the finished product roll 11 through the layered damping of forced rotation and return.

[0021] Main references Figure 1 and Figure 2 As shown, this solution also includes an interception component, which includes an interception frame 20 and an arc-shaped surface 21. The interception frame 20 is installed on the front side wall of the guide bracket 3 and is L-shaped. The arc-shaped surface 21 is located at the right-angled edge of the inner cavity of the interception frame 20 and is circular. The finished material roll 11, under the buffering and damping action of the multi-layer buffer blocks 6, stops along the arc-shaped surface 21 in the inner cavity of the interception frame 20, so that the finished material roll 11 is intercepted in the inner cavity of the interception frame 20 after rolling, so as to be collected. This utility model uses the interception frame 20 and the arc-shaped surface 21 to form a limiting and blocking mechanism to accurately intercept the finished material roll 11 after being damped by the buffer blocks 6. The two work together to construct a closed-loop space, stably storing the finished material roll 11 in the designated position of the interception frame 20, preventing it from falling due to inertia and other factors, ensuring the continuity and reliability of automated material collection, and improving the material collection process.

[0022] This solution also includes: a support frame 12 and a support seat 13. One end of the support frame 12 is fixedly installed on the side wall of the right guide bracket 3; the support seat 13 is installed on the other end of the support frame 12, and an arc-shaped groove is provided at the top of the support seat 13; wherein, the spool 10 is placed in the inner cavity of the support seat 13, and the support seat 13 can support the position of the spool 10 to ensure its stability during the winding process; it also includes: a coupling sleeve 14 and a first positioning pin 15. The coupling sleeve 14 is set as a hollow sleeve structure, and the spool 10 is inserted into one side of the coupling sleeve 14; the first positioning pin 15 is threaded through the outer wall of the coupling sleeve 14 and the spool 10 in the vertical direction. Specifically, the first positioning pin 15 is composed of a threaded rod and a positioning bolt. The threaded rod passes through the outer wall of the coupling sleeve 14 and the spool 10, and is threaded onto the first positioning pin 15 by means of the positioning bolt. The first positioning pin 15 is used to lock the coupling sleeve 14 and the reel 10 in place. The system also includes a motor frame 17, a motor 18, a drive shaft 19, and a second positioning pin 16. One end of the motor frame 17 is fixedly mounted on the side wall of the right guide bracket 3. The motor 18 is mounted on the other end of the motor frame 17. One end of the drive shaft 19 is connected to the output end of the motor 18, and the other end of the drive shaft 19 is inserted into the other side of the coupling sleeve 14. The second positioning pin 16 is threaded vertically through the outer walls of the coupling sleeve 14 and the drive shaft 19. Specifically, the second positioning pin 16 consists of a threaded rod and a positioning bolt. The threaded rod penetrates the outer walls of the coupling sleeve 14 and the drive shaft 19, and the positioning bolt is threaded onto the second positioning pin 16, thus locking the coupling sleeve 14 and the drive shaft 19 in place. In addition, the drive shaft 19, the connecting sleeve 14, and the winding shaft 10 are arranged with their axes collinear. When the drive shaft 19 drives the connecting sleeve 14 and the winding shaft 10 to rotate, the three can rotate coaxially. One end of the finished material roll 11 is fixed to the outer wall of the winding shaft 10. With the help of the activated motor 18, the drive shaft 19, the connecting sleeve 14, and the winding shaft 10 are made to rotate synchronously, so that the finished material roll 11 is gradually wound on the winding shaft 10 under the guidance of the winding machine body 1.

[0023] It is worth noting that in this application, the main body 1 of the winding machine is a commercially available plastic bag winding machine, which is sufficient to wind and collect plastic bags. It will not be described or limited here. After the finished material roll 11 is wound and collected on the roll 10, the free end of the finished material roll 11 is glued to its own outer wall to fix it, so as to prevent it from scattering during the subsequent rolling and collection process. This is existing technology and can meet the above-mentioned usage requirements. The model of the above-mentioned existing components will not be limited or described in detail here.

[0024] The working principle of a plastic bag production winding machine in this embodiment is as follows: One end of the finished material roll 11 is fixed to the outer wall of the roll 10. The motor 18 is turned on to make the drive shaft 19, the connecting sleeve 14 and the roll 10 rotate synchronously so that the finished material roll 11 is gradually wound on the roll 10 under the guidance of the winding machine body 1. After winding, the free end of the finished material roll 11 is positioned on its own outer wall to ensure the integrity of the finished material roll 11 and the roll 10 during the subsequent rolling and falling process. Remove the first positioning pin 15 from the coupling sleeve 14 to release it from the limiting lock on the reel 10. Lift the reel 10 and the finished product roll 11 away from the placement slot at the top of the guide bracket 3, allowing the reel 10 to roll down the inclined front wall of the guide bracket 3. As the reel 10 rolls down, the finished product roll 11 on the outer wall of the reel 10 first contacts the buffer block 6, driving the buffer block 6 to rotate downwards. The rotating buffer block 6 causes the rotating rod 4, the first connecting seat 8, and the material embedded in the first connecting seat 8 to rotate downwards. The ends of the torsion spring 7 in the cavity rotate downwards synchronously. At this time, the torsion spring 7 is forced to undergo torsional deformation until the finished material roll 11 rolls downwards and disengages from the buffer block 6. Under the action of the elastic force of the torsion spring 7, the buffer block 6 is driven to rotate in the opposite direction to return to its initial position. Similarly, during the process of the roll 10 rolling down along the guide bracket 3, the finished material roll 11 causes multiple sets of buffer blocks 6 to be forced to rotate and reset after rotation. Under the layered damping of multiple sets of buffer blocks 6, the finished material roll 11 is assisted in achieving a buffering effect during its rolling down process. The finished material roll 11, under the buffering and damping action of the multi-layer buffer block 6, stops along the arc surface 21 in the inner cavity of the interceptor frame 20, so that the finished material roll 11 is intercepted in the inner cavity of the interceptor frame 20 after rolling, so as to be collected. This invention constructs a dynamic damping buffer system using multiple sets of relatively rotating buffer blocks 6 to control the feeding speed of the finished material roll 11 and brake it quickly, thereby improving automation and production efficiency and preventing damage to the material roll. The torsion spring 7 is used to realize the automatic reverse rotation and reset of the buffer block 6, ensuring the continuous damping function during continuous feeding and reducing labor costs. The limiting and blocking mechanism composed of the interceptor 20 and the arc-shaped surface 21 accurately intercepts and limits the finished material roll 11 after damping and buffering, preventing it from falling and ensuring the integrity and reliability of the automated material receiving process.
