Description

Technical Field

[0001] This utility model relates to the field of PE plastic film cutting waste treatment technology, and in particular to a PE plastic film quantitative cutting waste collection device. Background Technology

[0002] During the production and processing of PE plastic film, the quantitative cutting process generates a large amount of waste material. If this waste is not collected and processed efficiently and promptly, it will not only waste resources but may also lead to a dirty and messy production environment due to indiscriminate dumping, and even pose safety hazards. Traditional PE plastic film waste collection devices generally have the following problems:

[0003] Most of the equipment relies on manual opening and closing of the feeding port, resulting in low waste collection efficiency and operational errors, which makes it difficult to meet the automation requirements of modern production lines. At the same time, manual operation increases the frequency of workers' contact with waste, posing safety risks.

[0004] Existing equipment typically only collects waste materials. Subsequent heating, softening, conveying, and granulation require separate processing by other equipment, resulting in a lengthy process flow, large equipment footprint, and the risk of waste spillage or pollution during intermediate transfer processes.

[0005] Therefore, how to provide a device for collecting waste material from quantitative cutting of PE plastic film is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] One objective of this invention is to provide a PE plastic film quantitative cutting waste collection device. This invention can realize the automated quantitative collection, heating softening and granulation of waste in an integrated manner. The integrated structural design simplifies the process flow, improves waste recycling efficiency, and reduces manual intervention. At the same time, the adjustable granulation perforated plate enhances the flexibility and stability of waste treatment.

[0007] A PE plastic film quantitative cutting waste collection device according to an embodiment of the present utility model includes a collection box and a conveying trough;

[0008] The bottom of the collection box is equipped with a heating base, and movable doors are movably installed on both sides of the upper part of the collection box through a rotating shaft. The conveying trough is fixedly installed on the bottom of the inner side of the collection box, and the heating end of the heating base is fixedly connected to the bottom of the conveying trough.

[0009] The side walls of the collection box are fixedly connected to the pivot of the movable door by connecting rods on both sides. An electric telescopic rod is movably installed at the other end of the connecting rod through the pivot. The electric telescopic rod is movably connected to the collection box through the pivot. A drive shaft is rotatably installed inside the conveying trough. An auger blade is fixedly welded to the outer wall of the drive shaft.

[0010] Furthermore, a discharge hole is provided at the lower rear side of the collection box, which is connected to the discharge end of the conveying trough to form a waste discharge channel.

[0011] Furthermore, a discharge port is fixedly provided on the rear side of the collection box corresponding to the discharge hole. A granulation perforated plate is detachably inserted into the discharge port, and the granulation perforated plate is evenly distributed with forming through holes. A handle is provided on the top of the granulation perforated plate.

[0012] Furthermore, a servo motor is fixedly installed on the lower front side of the collection box. The output shaft of the servo motor is connected to the rotating shaft seat through a transmission mechanism to drive the auger blades to rotate.

[0013] Furthermore, an annular slot is provided on the inner wall of the discharge port near the collection box, and the outer edge of the granulation plate is fitted into the slot to achieve detachable installation.

[0014] Furthermore, a base is fixedly installed at the bottom of the heating seat, and support legs are provided at the four corners of the bottom of the base.

[0015] Furthermore, the electric telescopic rod is hinged to a fixed seat on the outer wall of the collection box via a pivot seat, and the hinge point forms a triangular transmission structure with the pivot and connecting rod of the movable door to ensure the smooth opening and closing of the movable door.

[0016] Furthermore, the spiral blades of the auger maintain a uniform gap with the inner wall of the conveying trough, and the blade pitch gradually decreases along the conveying direction to enhance the waste pushing efficiency.

[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model uses a triangular transmission structure formed by an electric telescopic rod and a connecting rod to drive the opening and closing of the movable door. This allows for precise control of the door's opening degree, ensuring that waste falls quantitatively and directionally into the collection box, avoiding errors and safety hazards caused by manual operation. At the same time, the smooth opening and closing design of the movable door effectively prevents waste from scattering or generating dust during the collection process, thus improving the cleanliness of the working environment.

[0019] 2. This utility model, by tightly fitting the heating seat to the bottom of the conveying trough, can quickly transfer heat to the conveying trough, so that the PE plastic film waste is evenly heated and softened during the conveying process. Combined with the variable pitch spiral structure of the auger blades, on the one hand, the decreasing pitch design generates a compressive propulsion force on the softened waste, enhancing the conveying efficiency. On the other hand, the uniform gap design between the spiral blades and the inner wall of the conveying trough avoids the waste from getting stuck, ensuring a continuous and stable conveying process and reducing the equipment failure rate.

[0020] 3. In this utility model, the softened waste material is pushed by the auger blades through the forming holes of the granulation plate and directly extruded into granular material. This integrated process of heating-conveying-granulation eliminates the intermediate waste transfer link in the traditional process, reducing energy loss and material pollution. At the same time, the granulation plate adopts a detachable slot installation, and users can quickly replace the plate with different hole diameters according to their needs, flexibly adjust the particle size, and meet diverse recycling needs.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0028] refer to Figure 1-4 A device for collecting waste material from quantitative cutting of PE plastic film includes a collection box 3 and a conveying trough 16;

[0029] The collection box 3 has a rectangular hollow structure, and a heating seat 2 is fixedly installed at its bottom. The heating seat 2 is made of electric heating element, and its top heating end is completely attached to the bottom of the conveying trough 16. It is fixedly connected by bolts to ensure that heat can be efficiently transferred to the conveying trough 16.

[0030] In this embodiment, movable doors 4 are symmetrically installed on both sides of the upper part of the collection box 3 via a pivot axis. The two movable doors 4 can be opened and closed around the pivot axis to form a waste inlet.

[0031] refer to Figure 1 The opening and closing drive mechanism of the movable door 4 includes a connecting rod 5 and an electric telescopic rod 6. The connecting rod 5 is hinged between the two side walls of the collection box 3 and the pivot of the movable door 4. The other end of the connecting rod 5 is hinged to the piston rod end of the electric telescopic rod 6 through the pivot. The fixed end of the electric telescopic rod 6 is hinged to the fixed seat on the outer side wall of the collection box 3 through the pivot seat 7. The hinge point, together with the pivot of the movable door 4 and the connecting rod 5, forms a stable triangular transmission structure.

[0032] In this embodiment, when the electric telescopic rod 6 extends or retracts, the movable door 4 can be smoothly driven to rotate around the pivot through the transmission action of the connecting rod 5, thereby achieving precise opening and closing control.

[0033] refer to Figure 1 and Figure 4 The conveying trough 16 is horizontally fixedly installed at the bottom of the inner side of the collection box 3. The drive shaft 17 is rotatably installed inside it along the axial direction. The outer wall of the drive shaft 17 is spirally welded with an auger blade 18. The spiral blade of the auger blade 18 maintains a uniform gap with the inner wall of the conveying trough 16, which ensures the efficiency of waste conveying and avoids jamming.

[0034] In particular, the pitch of the blades gradually decreases along the conveying direction. This variable pitch design can compress the waste material during the conveying process and enhance the pushing effect.

[0035] refer to Figure 1-4 The lower rear side of the collection box 3 has a discharge hole 15, which is directly connected to the discharge end of the conveying trough 16. A discharge port 10 is fixedly provided on the outside of the discharge hole 15. An annular slot 14 is provided on the inner wall of the discharge port 10 near the collection box 3. The outer edge of the granulation plate 11 is fitted into the slot 14. The slot 14 limits the detachable installation. Several forming through holes 12 are evenly distributed on the granulation plate 11. When waste passes through the granulation plate 11, it can be formed into granular material under the action of extrusion, which is convenient for subsequent recycling. A handle 13 is provided on the top of the granulation plate 11 for easy replacement of the granulation plate 11.

[0036] A servo motor 9 is fixedly installed on the lower front side of the collection box 3. The output shaft of the servo motor 9 is connected to the transmission shaft 17 through a transmission mechanism such as belt drive or gear drive. When the servo motor 9 is started, it can drive the transmission shaft 17 and the auger blade 18 to rotate synchronously, so as to realize the continuous conveying of waste materials.

[0037] The heating base 2 is fixedly connected to the base 1 at the bottom. The base 1 is a rectangular flat plate structure with vertical support legs at the four corners of its bottom. The support legs stably support the entire device on the ground.

[0038] Working Principle: When waste is generated during the cutting process of PE plastic film, the control system receives a waste collection command. At this time, the electric telescopic rod 6 starts to move, and its piston rod extends outward. Since the fixed end of the electric telescopic rod 6 is hinged to the fixed seat on the outer wall of the collection box 3 through the rotating shaft seat 7, and the end of the piston rod is connected to the rotating shaft of the movable door 4 through the connecting rod 5, a stable triangular transmission structure is formed. As the piston rod of the electric telescopic rod 6 extends, the connecting rod 5 will be displaced under its drive, thereby pushing the movable door 4 to rotate around its mounting rotating shaft into the collection box 3. The two movable doors 4 gradually open, forming a channel for waste to enter. The operator or waste conveying equipment sends the PE plastic film cutting waste through the opened movable door 4 into the collection box. Inside the collection box 3, during this process, the opening angle of the movable door 4 can be precisely adjusted by controlling the extension of the electric telescopic rod 6 to adapt to different waste disposal needs. After the waste enters the collection box 3, it will fall directly onto the conveying trough 16. At this time, the heating seat 2 starts to work, and the electric heating element converts electrical energy into heat energy. Since the heating end of the heating seat 2 is in close contact with the bottom of the conveying trough 16, the heat will be quickly transferred to the conveying trough 16, thereby heating the PE plastic film waste in the conveying trough 16. Under the action of heating, the PE plastic film gradually softens, reducing its viscosity and hardness, which facilitates subsequent conveying and granulation. At the same time, the servo motor 9 starts, and its output shaft begins to rotate, transmitting power to the belt drive or gear drive and other transmission mechanisms. The drive shaft 17 inside the conveying trough 16 begins to rotate. Since the auger blade 18 is fixedly welded to the outer wall of the drive shaft 17, the rotation of the drive shaft 17 will drive the auger blade 18 to rotate synchronously. During the rotation, the spiral blades of the auger blade 18 will generate an axial thrust on the softened waste, conveying the waste along the conveying trough 16 towards the discharge end. It is particularly worth mentioning that the pitch of the auger blade 18 gradually decreases along the conveying direction. When the waste first enters the conveying trough 16, the larger pitch allows the waste to enter the conveying area of ​​the auger blade 18 more smoothly, avoiding waste accumulation. As the waste is conveyed towards the discharge end, the gradually decreasing pitch will compress the waste, making the waste more compact during the conveying process, further improving the efficiency of waste conveying. To ensure efficient conveying and high-quality granulation, when waste material is conveyed to the discharge end of the conveying trough 16 by the auger blade 18, it enters the discharge port 10 through the discharge hole 15 at the lower rear of the collection box 3. A granulation perforation plate 11 is installed inside the discharge port 10, with evenly distributed forming through holes. Under the continuous pushing of the auger blade 18, the softened and compressed waste material is squeezed and extruded through the forming through holes on the granulation perforation plate 11. During the extrusion process, the waste material is formed into granules and discharged from the discharge port 10, completing the waste collection and granulation process. If it is necessary to replace the granulation perforation plate 11 with a different specification to obtain granules of different sizes, the operator can directly pull the granulation perforation plate 11 out of the annular slot 14 on the inner wall of the discharge port 10.Then insert the new granulation plate 11. The operation is simple and convenient, requiring no complicated tools or steps.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
