Abstract
Description
Technical Field
[0001] This application relates to the field of waste membrane collection, and more particularly to a waste membrane collection device. Background Technology
[0002] Typically, a waste membrane collection device includes a gripper mechanism for grabbing the waste membrane, an air blowing device for guiding the waste membrane into the collection area, and a collection container. The gripper mechanism is responsible for grabbing the torn waste membrane, and then the air blowing device blows air to make the waste membrane fall into the collection container along the airflow direction.
[0003] However, existing air-blowing devices have significant drawbacks, namely unstable airflow control. In actual operation, the size and direction of the airflow are difficult to control precisely, sometimes being too strong and sometimes too weak, and the direction can also deviate. This causes waste membranes to easily fly out of the collection device due to abnormal airflow changes. This not only requires manual reprocessing, consuming extra time and effort, but also disrupts the normal collection process, severely impacting operational efficiency. Furthermore, frequent manual intervention and process interruptions greatly limit overall capacity expansion, failing to meet the ever-increasing production demands. Utility Model Content
[0004] In view of this, this application proposes a waste membrane collection device to solve at least one of the above problems.
[0005] A waste membrane collection device includes a tearing assembly, a blowing assembly, and a suction assembly. The tearing assembly includes openable and closable grippers and a drive component drivingly connected to the grippers. The grippers are used to grasp the peeled waste membrane, and the drive component is configured to control the three-dimensional motion trajectory of the grippers. The blowing assembly includes a body, an air blowing channel, and a first air blowing generator. The body has a through-hole, the air blowing channel is embedded in the body, one end of the air blowing channel is connected to the first air blowing generator, and the other end is exposed in the opening. The grippers are positioned corresponding to the opening. The suction assembly is connected to the blowing assembly. The suction assembly includes a hood and a second air blowing generator. One end of the hood is connected to the body and is positioned corresponding to the opening, and the second air blowing generator is connected to the hood.
[0006] In some possible implementations, a duct and a collection box are also included, the duct being connected to the other end of the shroud, and the end of the duct away from the shroud being inserted into the collection box.
[0007] In some possible implementations, a control unit is also included, which is electrically connected to the first air generator, the second air generator, and the drive unit. The control unit is used to adjust the airflow parameters of the first air generator and the second air generator according to the movement position of the gripper and / or the peeling state of the waste film. The airflow parameters include airflow intensity, direction change frequency, and duration. The control unit is communicatively connected to the drive unit to synchronize the displacement trajectory and opening / closing state of the gripper with the start and stop sequence of the airflow.
[0008] In some possible implementations, the air blowing channel includes a main channel and at least two secondary channels communicating with the main channel, the end of the main channel away from the secondary channels being connected to the first air blowing generator, and the end of the secondary channels away from the main channel being exposed in the opening.
[0009] In some possible implementations, the ends of the two secondary channels furthest from the main channel are symmetrically exposed in the opening.

[0014] In some possible implementations, the device also includes a fixing plate and a fixing bracket connected to the fixing plate, wherein the tearing assembly, the blowing assembly and the suction assembly are all disposed on the fixing plate.
[0015] In the waste membrane collection device provided in this application, the openable grippers of the tearing assembly can effectively grasp the peeled waste membrane. The drive component controls the three-dimensional movement trajectory of the grippers, enabling them to flexibly reach different positions for precise grasping, thus improving the accuracy and efficiency of grasping compared to traditional gripper mechanisms. The blow-off assembly, by embedding the air-blowing channel in the main body, with one end connected to the first air-blowing generator and the other end exposed in the opening, and the grippers corresponding to the opening, achieves stable airflow delivery.

[0029] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0030] See Figure 1This application provides a waste film collection device 100 for efficiently and stably collecting waste film generated during the production process, reducing the scattering of waste film during collection, and improving operational efficiency.
[0031] The waste film collection device 100 includes a tearing assembly 10, a blow-off assembly 20, and a suction assembly 30. The tearing assembly 10 is movably disposed on one side of the blow-off assembly 20, and the suction assembly 30 is disposed on the other side of the blow-off assembly 20. The tearing assembly 10 is used to grasp and peel off the waste film attached to the product surface, and the blow-off assembly 20 is used to blow the waste film in a designated direction by air after peeling for subsequent collection. The suction assembly 30 is used to guide the waste film to the collection area by airflow after blow-off.
[0032] The peeling assembly 10 includes an openable gripper 11 and a drive unit 12 that drives the gripper 11. The gripper 11 is used to grasp the waste film to be peeled, and the drive unit 12 controls the spatial movement trajectory of the gripper 11, thereby peeling off the waste film. By precisely controlling the movement of the gripper 11, waste film in different positions and states can be grasped more flexibly and accurately, improving the success rate and efficiency of peeling. Specifically, the drive unit 12 includes a stepper motor.
[0033] See Figure 2 , Figure 3 and Figure 5 The blow-off assembly 20 includes a body 21, an air-blowing channel 22, and a first air-blowing generator 23. The body 21 has a through-hole 211. The air-blowing channel 22 is embedded in the body 21, with one end connected to the first air-blowing generator 23 and the other end exposed in the through-hole 211. A gripper 11 is located at the through-hole 211. The airflow generated by the first air-blowing generator 23 is blown out through the air-blowing channel 22 from the through-hole 211. Since the gripper 11 is directly facing the through-hole 211, the blown airflow can directly act on the waste membrane gripped by the gripper 11, blowing the waste membrane towards the suction assembly 30. This makes the airflow more concentrated and stable, effectively reducing the problem of difficulty in accurately controlling the size and direction of the airflow, and lowering the probability of the waste membrane scattering due to abnormal airflow changes.
[0034] See Figure 1 and Figure 5 The suction assembly 30 includes a hood 31 and a second air generator 32. One end of the hood 31 is connected to the main body 21 and faces the opening 211. The second air generator 32 is connected to the hood 31 through an air inlet 311. The second air generator 32 blows air into the hood 31, forming a stable airflow field. When the waste membrane is blown towards the hood 31 by the blow-off assembly 20, the airflow inside the hood 31 can adsorb the waste membrane and guide it to the subsequent collection area. This helps to ensure that the waste membrane is collected smoothly and reduces the possibility of its escape.
[0035] See Figure 1In this embodiment, the waste membrane collection device 100 further includes a ventilation duct 40 and a collection box 50. The ventilation duct 40 is connected to one end of the ventilation hood 31, and the other end, away from the ventilation hood 31, is inserted into the collection box 50. The ventilation duct 40 further guides the airflow and waste membrane, allowing the waste membrane to smoothly enter the collection box 50 along the ventilation duct 40. The collection box 50 is used to centrally store the waste membrane, facilitating subsequent cleaning and processing.
[0036] See Figure 1 In this embodiment, the waste film collection device 100 further includes a fixing plate 41 and a fixing bracket 42. The fixing bracket 42 connects to the fixing plate 41. The fixing plate 41 includes a first surface 411 and a second surface 412 opposite to it. A tearing component 10, a blowing component 20, and a suction component 30 are respectively provided at both ends of the first surface 411; a wind duct 40 and a collection box 50 are respectively provided at both ends of the second surface 412. Through holes (not shown) are provided at both ends of the fixing plate 41, and the wind duct 40 and the wind cover 31 are connected through the through holes. The fixing plate 41 provides a stable mounting base for each component, ensuring that their relative positions are fixed. The fixing bracket 42 is used to securely mount the fixing plate 41, bear the weight of each component, and provide reliable support for the normal operation of the waste film collection device 100.
[0037] See Figure 1 and Figure 5 In this embodiment, the waste membrane collection device 100 further includes a control unit 60. The control unit 60 is electrically connected to the first air generator 23, the second air generator 32, and the drive unit 12. The control unit 60 adjusts the airflow parameters of the first air generator 23 and the second air generator 32, including airflow intensity, direction change frequency, and duration, according to the movement position of the gripper 11 or the peeling state of the waste membrane. The control unit 60 is communicatively connected to the drive unit 12 to synchronize the displacement trajectory, opening and closing state of the gripper 11, and the start and stop sequence of the airflow. The control unit 60 can be a microcontroller, a programmable logic controller, or an industrial control computer.
[0038] In actual operation, when the grippers 11 of the tearing assembly 10 approach and grasp the waste film under the action of the drive component 12, the control unit 60 monitors the position information and opening / closing status of the grippers 11 in real time. When the grippers 11 successfully grasp the waste film and begin peeling, the control unit 60 calculates the required airflow parameters of the first air generator 23 according to the preset program and the current movement position, and sends a command to generate the corresponding airflow.
[0039] During the blown film process, if the control unit 60 detects that the waste film does not move along the expected trajectory (such as due to uneven material or gripping position deviation), it will adjust the airflow parameters of the first blown air generator 23 to ensure that the waste film is blown smoothly to the suction component 30.
[0040] When the waste membrane reaches the vicinity of the suction assembly 30, the control unit 60 adjusts the airflow parameters of the second air generator 32 according to its position and speed to generate appropriate suction, ensuring that the waste membrane stably enters the air duct 40. At the same time, the control unit 60 synchronously controls the start and stop of the airflow to reduce unnecessary airflow consumption, save energy, and improve equipment stability.
[0041] See Figure 1 and Figure 3 In this embodiment, the air blowing channel 22 includes a main channel 221 and at least two connected secondary channels 222. The main channel 221 is connected to the first air blowing generator 23, and the ends of the secondary channels 222 away from the main channel 221 are exposed in the opening 211 and are arranged symmetrically. The symmetrical secondary channels 222 can apply force to the waste membrane separately, making the airflow direction more precise. The body 21 is also provided with a notch 212, which connects to the opening 211 to allow the gripper 11 to enter and exit, avoiding motion interference.
[0042] In this embodiment, the hood 31 adopts a telescopic corrugated pipe structure, and a sealing ring (not shown) is provided at the connection end with the body 21. The telescopic structure makes the hood 31 flexible, and its position can be adjusted according to the real-time position of the waste film during operation to ensure accurate capture of the waste film.
[0043] See Figure 5 In this embodiment, the waste membrane collection device 100 further includes a differential pressure sensor 70 and a vibration detection module 80. The differential pressure sensor 70 is disposed in the air blowing channel 22 to monitor changes in airflow pressure. The vibration detection module 80 is fixed to the surface of the gripper 11 to detect the detachment state of the waste membrane. Both are electrically connected to the control unit 60.
[0044] When the first air generator 23 is activated, airflow is blown out through the air channel 22, and the differential pressure sensor 70 monitors changes in airflow pressure. If abnormal pressure fluctuations occur (such as a sudden increase or decrease), the sensor feeds a signal back to the control unit 60, which analyzes the signal and adjusts the airflow parameters or issues an alarm if necessary to prevent malfunctions from affecting the collection effect. Simultaneously, the vibration detection module 80 monitors the vibration state of the gripper 11. If waste membrane detachment is detected, a signal is sent to the control unit 60, which then adjusts the negative pressure of the second air generator 32 to ensure timely adsorption of the waste membrane.
[0045] The top of the collection box 50 is equipped with an adjustable vent 51 and a filter 52. The vent 51 allows for adjustable ventilation to accommodate different collection needs and prevents air accumulation from affecting the collection of waste membrane. The filter 52 intercepts fine particles to prevent environmental pollution or interference with subsequent treatment.
[0046] See Figure 1 and Figure 4In this embodiment, vortex generators 223 are respectively installed in the symmetrically arranged secondary channels 222. The vortex generators 223 are serrated metal sheets used to turbulentize the airflow in the blowing channel 22. Thus, when the airflow passes through the secondary channel 222, the serrated vortex generators 223 will disturb the airflow. When the airflow passes through the metal sheets, it will be forced to change its direction, forming multiple small-scale vortices, thereby transforming the originally relatively stable airflow into a turbulent state. In the turbulent state, the contact area between the airflow and the waste membrane is larger, and it can exert a more sufficient force on the waste membrane. Compared with laminar airflow, it can more effectively drive the waste membrane to move, enhance the blowing power, and ensure that even waste membranes with large mass or irregular shape can be smoothly blown to the suction assembly 30.
[0047] The above description describes some specific embodiments of this application, but in actual applications, the application should not be limited to these embodiments. For those skilled in the art, other modifications and alterations made based on the technical concept of this application should fall within the protection scope of this application.
