Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology for vacuum forming machines, specifically a waste winding mechanism for vacuum forming machines. Background Technology

[0002] In the thermoforming process, to ensure product forming accuracy, plastic sheets larger than the product size are typically used, generating a large amount of waste material around the product's edges. Directly discarding this waste not only wastes plastic raw materials but also increases environmental treatment costs. For recycling, a winding mechanism is needed to neatly wind the continuously generated waste material for subsequent crushing, melting, and regeneration. Therefore, the waste winding mechanism has become a key auxiliary device in thermoforming production lines, ensuring production continuity and reducing material loss.

[0003] Currently, most vacuum forming machines on the market use traditional bolt-tightening structures to fix the waste material winding mechanism between the winding drum and the winding roller. However, this method requires manual tightening of each bolt, resulting in low installation efficiency and difficulty in ensuring uniform tightening force. This can easily lead to misalignment of the winding drum and the winding roller, causing waste material to deviate during winding, uneven edges of the rolled material, and in most vacuum forming machines, the layers of waste material are loosely bonded during winding, making it prone to interlayer slippage and fluffy rolled material, which is not conducive to subsequent storage and transportation.

[0004] Therefore, we propose a waste material winding mechanism for a vacuum forming machine to solve the problems mentioned above. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model: The purpose of this utility model is to provide a waste material winding mechanism for a vacuum forming machine to solve the problems currently found in the market as described in the background.

[0006] 2. Technical Solution: To achieve the above objectives, the present invention provides the following technical solution: a waste material winding mechanism for a thermoforming machine, comprising a frame, a winding roller mounted on the frame via bearings, a winding cylinder sleeved on the outside of the winding roller, and a control component and a fixing component installed inside the winding roller, wherein the control component is used to drive the fixing component to move radially to clamp or release the winding cylinder; The frame is also equipped with a telescopic component, and the output end of the telescopic component is connected to a pressure roller component, which is used to apply a preset pressure to the waste material during the winding process.

[0007] Furthermore, the control component includes a drive shaft, a guide rod, a drive disc, and a threaded section; The drive shaft is rotatably mounted inside the take-up roller via bearings, and the drive shaft is provided with several sets of threaded segments at equal intervals. The guide rod is fixedly installed inside the take-up roller, and several drive discs are fitted and sleeved on the outer side of the guide rod; Each of the drive discs is threadedly engaged with a corresponding threaded segment.

[0008] The above technical solution enables the drive disc to move along the direction of the guide rod when the drive shaft rotates.

[0009] Furthermore, the fixing component includes a fixing plate, a movable rod, a return spring, and a protrusion; One end of the movable rod is fixed to the side of the fixed plate facing the take-up roller, and the other end extends into the inside of the take-up roller. The protrusion is fixed to the side of the movable rod, and the protrusion slides in cooperation with the inner wall of the take-up roller. The reset spring is sleeved on the outer periphery of the movable rod, and its two ends are respectively connected to the inner wall of the fixed plate and the winding roller, and is used to provide reset elastic force for the fixed plate; The fixing plate is located outside the take-up roller and is used to abut against the end face of the take-up drum.

[0010] The above technical solution enables the fixed plate to move stably.

[0011] Furthermore, the fixing plates are distributed at equal angles to the center of the take-up roller, and a rubber layer is provided on the side of the fixing plates away from the take-up roller.

[0012] The above technical solution enables the fixed plate to move closer to the winding drum, thereby stably fixing the winding drum.

[0013] Furthermore, the movable rod is inclined on the side closest to the corresponding drive disc, and the outer circumferential surface of the drive disc is arranged in an arc shape.

[0014] The above technical solution allows the drive disc to be displaced and pressed against the movable rod, thereby moving the movable rod.

[0015] Furthermore, the telescopic component includes an electric push rod, a base frame, a sleeve, a limiting rod, a fixing rod, and a pressure spring; The electric push rod is fixed on the frame, and a pressure sensor is installed at the output end of the electric push rod. A base frame is fixed at the top of the pressure sensor, and a sleeve is fixed at the lower end of the base frame. The sleeve is slidably sleeved on the outside of the limiting rod, and the limiting rod is fixed on the frame. The fixing rod is fixedly installed on the base frame, and a pressure spring is sleeved on the outer side of the fixing rod.

[0016] The above technical solution enables the pressure sensor to monitor the applied pressure value in real time, and pushes the base frame down through the electric push rod.

[0017] Furthermore, the pressure roller includes a support frame and a pressure roller body. The support frame is slidably mounted on the base frame, and the pressure roller body is rotatably mounted on the support frame. The support frame is sleeved on the outside of the fixed rod, and the two ends of the pressure spring are respectively connected to the support frame and the base frame.

[0018] The above technical solution enables flexible clamping through a pressure spring.

[0019] 3. Beneficial effects: Compared with the prior art, the waste material winding mechanism of the vacuum forming machine of this utility model, using the rotating drive shaft, achieves rapid clamping and release of the winding drum, which is easy to operate. The pressure roller, together with the pressure sensor and spring, achieves constant pressure and flexible clamping, effectively preventing loose winding and wrinkles, and improving winding quality and material changing efficiency. The specific details are as follows: After the empty take-up drum is placed around the outer circumference of the take-up roller, the drive shaft is manually driven to rotate, which drives the drive disc to move axially along the guide rod. During the movement, the inclined surface on the movable rod is squeezed, forcing the movable rod and the fixed plate at its end to move radially outward, pressing the inner wall of the take-up drum to achieve fast and uniform clamping with high stability. When changing the take-up drum, simply reverse the drive shaft to release it automatically. The operation is simple and greatly improves the material changing efficiency. (2) After the waste material is drawn out from the vacuum forming machine, it passes around the pressure roller and begins to wrap around the take-up drum. At this time, the electric push rod in the telescopic part pushes the base frame down. The pressure sensor monitors the applied pressure value in real time to ensure that the pressure is constant. The pressure spring achieves flexible pressing, which can set the initial pressure and adapt to the change of the take-up diameter. It always keeps the waste material layers tightly attached and avoids loosening and wrinkling. Attached Figure Description

[0026] Please see Figure 1-5A waste material winding mechanism for a thermoforming machine includes a frame 1, on which a winding roller 2 is mounted via bearings. A winding drum 5 is sleeved on the outside of the winding roller 2, and a control component 3 and a fixing component 4 are installed inside the winding roller 2. The control component 3 is used to drive the fixing component 4 to move radially to clamp or release the winding drum 5. The control component 3 includes a drive shaft 31, a guide rod 32, a drive disc 33, and threaded sections 34. The drive shaft 31 is rotatably mounted inside the winding roller 2 via bearings, and the drive shaft 31 is provided with several sets of threaded sections 34 at equal intervals. The guide rod 32 is fixedly mounted inside the winding roller 2, and several drive discs 33 are fitted and sleeved on the outside of the guide rod 32. Each drive disc 33 is threadedly engaged with a corresponding threaded section 34. The fixing component 4 includes a fixing plate 41. The system comprises a movable rod 42, a return spring 43, and a protrusion 44. One end of the movable rod 42 is fixed to the side of the fixed plate 41 facing the take-up roller 2, and the other end extends into the inside of the take-up roller 2. A protrusion 44 is fixed to the side of the movable rod 42, and the protrusion 44 slides in cooperation with the inner wall of the take-up roller 2. The return spring 43 is sleeved on the outer periphery of the movable rod 42, and its two ends are respectively connected to the fixed plate 41 and the inner wall of the take-up roller 2, and is used to provide a return spring force for the fixed plate 41. The fixed plate 41 is located on the outside of the take-up roller 2 and is used to abut against the end face of the take-up drum 5. The fixed plate 41 is distributed at equal angles with respect to the center of the take-up roller 2, and a rubber layer is provided on the side of the fixed plate 41 away from the take-up roller 2. The movable rod 42 is inclined on the side close to the corresponding drive disk 33, and the outer periphery of the drive disk 33 is arranged in an arc shape. First, the empty take-up drum 5 is placed around the outer periphery of the take-up roller 2. Then, the drive shaft 31 is driven to rotate. Through the threaded engagement of each threaded section 34 with the corresponding drive disc 33, and the limiting effect of the guide rod 32, multiple drive discs 33 are driven to move axially along the guide rod 32. The outer periphery of the drive disc 33 has an arc-shaped structure. During its movement, it squeezes the inclined surface on the movable rod 42, forcing the movable rod 42 together with the fixed plate 41 at its end to move radially outward. Multiple fixed plates 41 expand outward synchronously, pressing the inner wall of the take-up drum 5 to achieve fast and uniform clamping. The return spring 43 is compressed during the clamping process, providing elastic return force for subsequent release. The frame 1 is also equipped with a telescopic component 6. The output end of the telescopic component 6 is connected to a pressure roller 7, which is used to apply a preset pressure to the waste material during the winding process. The telescopic component 6 includes an electric push rod 61, a base frame 62, a sleeve 63, a limiting rod 64, a fixing rod 65, and a pressure spring 66. The electric push rod 61 is fixed on the frame 1, and a pressure sensor is installed at the output end of the electric push rod 61. The top of the pressure sensor is fixed to the base frame 62, and the lower end of the base frame 62 is fixed to the sleeve 63, which is slidably sleeved. The limiting rod 64 is fixed to the frame 1 on the outside of the limiting rod 64; the fixing rod 65 is fixedly installed on the base frame 62, and the pressure spring 66 is sleeved on the outside of the fixing rod 65; the pressure roller 7 includes a support frame 71 and a pressure roller body 72. The support frame 71 is slidably mounted on the base frame 62, and the pressure roller body 72 is rotatably mounted on the support frame 71. The support frame 71 is sleeved on the outside of the fixing rod 65, and the two ends of the pressure spring 66 are respectively connected to the support frame 71 and the base frame 62. After the waste material is drawn out from the vacuum forming machine, it passes around the pressure roller 7 and begins to wind onto the take-up drum 5. At this time, the electric push rod 61 in the telescopic component 6 pushes the base frame 62 to move down. The pressure sensor monitors the applied pressure value in real time and feeds the signal back to the control system to realize closed-loop pressure control, ensuring constant clamping force and avoiding sudden pressure changes due to the increase in the winding diameter. The base frame 62 drives the fixed rod 65 and the pressure spring 66 sleeved on it to move down synchronously. The support frame 71 maintains an elastic connection with the base frame 62 under the action of the pressure spring 66. The pressure roller body 72 rotates on the support frame 71, always rolling in close contact with the surface of the waste material, applying stable pre-pressure to prevent loosening of the winding or slippage between layers.

[0027] Working principle: When using the waste reeling mechanism of this vacuum forming machine, such as Figure 1-5 As shown, firstly, an empty take-up drum 5 is placed around the outer periphery of the take-up roller 2. Then, the drive shaft 31 is rotated, driving multiple drive discs 33 to move axially along the guide rod 32. During the movement, the inclined surface on the movable rod 42 is squeezed, forcing the movable rod 42 to press against the inner wall of the take-up drum 5, thus achieving rapid installation. After the waste material is drawn out from the vacuum forming machine, it passes around the pressure roller 7 and begins to wind around the take-up drum 5. The pressure value applied is monitored in real time by the pressure sensor, and the signal is fed back to the control system to drive the electric push rod 61 to open and close. This, in turn, drives the base frame 62 to move synchronously with the fixed rod 65 and the pressure spring 66 fitted on it. Under the action of the pressure spring 66, the pressure roller body 72 always rolls in close contact with the surface of the waste material, applying a stable pre-pressure to prevent loosening of the take-up or slippage between layers.
