Description

Technical Field

[0001] This utility model relates to the field of packaging waste recycling technology, specifically a device for recycling and reusing foam packaging scraps. Background Technology

[0002] With the rapid development of industries such as logistics, electronics, and home appliances, foam materials (such as EPS and EPE) are widely used in product packaging due to their advantages of being lightweight, having good cushioning properties, and being low in cost, in order to protect products from collision damage during transportation and storage. In the production and processing of foam packaging, the foam raw materials need to be cut and trimmed according to the product dimensions, generating a large amount of foam scrap. Simultaneously, after the products are unpacked, discarded foam packaging also generates a large amount of foam waste awaiting disposal. These two types of materials together constitute the main source of foam packaging scrap, and their generation continues to increase with the growth of packaging demand.

[0003] A search revealed existing technology (application number: CN217196396U), which describes "a foam processing scrap recycling device". This utility model uses a fan on the workbench to assist in collecting foam processing scraps into a collection box. At the same time, a motor-driven extrusion mechanism compresses the scraps in the collection box. The collection box can be easily operated through a fixing plate and a handle groove to complete the scrap recycling.

[0004] However, it lacks anti-splash protection structures and cutting positioning assistance functions for foam processing, and recycling relies solely on initial collection and compression by a fan, without a directional flow recycling channel, resulting in insufficient protection of scraps, inaccurate collection, and low recycling efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for recycling and reusing foam packaging scraps.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a foam packaging scrap recycling and reuse device, comprising: a workbench; a splash-proof assembly, including a protective cover, a connecting plate, a first baffle and a second baffle, the protective cover being disposed on the workbench, one end of the connecting plate being welded to the protective cover, the bottom end of the connecting plate being connected to the workbench by bolts, and both the first baffle and the second baffle being slidably connected to the side wall of the protective cover; and a recycling assembly, including a recycling pipe, a fan and a collection box, the recycling pipe being welded to the bottom of the workbench, the fan being connected to the inside of the recycling pipe by bolts, and the collection box being welded to the bottom of the recycling pipe.

[0007] As a further description of the above technical solution:

[0008] The workbench is used to place the cutting device and the items to be cut. Both baffle one and baffle two are in contact with the items to be cut, and there are two baffles.

[0009] As a further description of the above technical solution:

[0010] The splash-proof assembly also includes: an observation window, fixedly connected to the side wall of the protective cover; and scale lines, welded to the bottom of the observation window, corresponding to the cutting position.

[0011] As a further description of the above technical solution:

[0012] A sliding block is welded to the side wall of the first baffle, and springs are provided on both sides of the first baffle. The two ends of the springs are welded to the sliding block and the inside of the protective cover, respectively.

[0013] As a further description of the above technical solution:

[0014] The splash-proof assembly also includes: a slide rail, which is connected to the cover by bolts and slidably connected to the second baffle; and an adjusting screw, which has two opposite threads, which is rotatably connected to the slide rail and threadedly connected to the second baffle.

[0015] As a further description of the above technical solution:

[0016] The recycling assembly also includes: a recycling through hole, which is set on the workbench and located above the recycling pipe; a guide plate, which is welded above the fan and is triangular pyramidal in shape; and multiple ventilation holes, which are located on the side wall of the guide plate.

[0017] As a further description of the above technical solution:

[0018] The recycling assembly also includes a door panel, which is rotatably connected to the side wall of the collection box and locked to the collection box by a locking pin.

[0019] This utility model has the following beneficial effects:

[0020] On the one hand, the combination of the protective structure and the adjustable limiting components forms a stable protective area for cutting operations. This not only reduces the range of scrap splashing during the cutting process, but also allows for flexible adjustment of the limiting state according to the size of the item to be cut, ensuring the stability of the item's position during cutting and avoiding cutting deviations caused by item displacement. At the same time, it enables visual monitoring and precise positioning of the cutting process, improving the standardization and accuracy of the cutting operation.

[0021] On the other hand, relying on directional airflow guidance and a dedicated recycling structure, an efficient scrap recycling channel is constructed, enabling the scrap generated from cutting to quickly enter the collection area, reducing its retention in the pipe. At the same time, the collection area can be easily opened and closed, facilitating regular cleaning. This not only achieves the effective recycling and reuse of foam packaging scraps, but also maintains a clean working environment. Attached Figure Description

[0034] Example 1:

[0035] like Figures 1 to 7 As shown, this embodiment provides a foam packaging scrap recycling and reuse device, including: a workbench 1; a splash-proof assembly 2, including a protective cover 21, a connecting plate 22, a first baffle 25, and a second baffle 29, the protective cover 21 is disposed on the workbench 1, one end of the connecting plate 22 is welded to the protective cover 21, the bottom end of the connecting plate 22 is connected to the workbench 1 by bolts, and the first baffle 25 and the second baffle 29 are slidably connected to the side wall of the protective cover 21; a recycling assembly 3, including a recycling pipe 32, a fan 33, and a collection box 36, the recycling pipe 32 is welded to the bottom of the workbench 1, the fan 33 is connected to the inside of the recycling pipe 32 by bolts, and the collection box 36 is welded to the bottom of the recycling pipe 32.

[0036] In addition, the cutting device is inside the protective cover 21. A fixed plate is bolted to the worktable. A rotating shaft is rotatably connected to the fixed plate. A reinforcing spring is sleeved on the rotating shaft. The two ends of the reinforcing spring are welded to the fixed plate and the rotating shaft, respectively. One end of the rotating shaft passes through the side wall of the protective cover 21 and is fixedly connected to a drive motor. A connecting plate is fixedly connected to the middle of the rotating shaft. A connecting shaft is rotatably connected to one end of the connecting plate. A cutting wheel is fixedly connected to the connecting shaft. Fixed sleeves are threaded to both ends of the connecting shaft. A second drive motor is fixedly connected to one end of the connecting shaft. A protective shell is provided on the outside of the second drive motor. The protective shell is provided with heat dissipation holes.

[0037] Specifically, the workbench 1 is used to place the cutting device and the items to be cut. Both baffle 1 25 and baffle 2 29 are in contact with the items to be cut, and there are two baffles 2 29.

[0038] In this embodiment, the workbench 1, the anti-splash component 2, and the recycling component 3 constitute a foam packaging scrap recycling and reuse device according to this application.

[0039] Understandable, Figure 6 The cutting device is shown only schematically, and the actual shape, size, position, and construction of these components are not subject to change. Figure 6 Due to limitations, the cutting device can also include, compared to Figure 6 More or fewer parts.

[0040] Example 2:

[0041] Specifically, the splash guard 2 also includes: an observation window 23, which is fixedly connected to the side wall of the protective cover 21; and a scale line 24, which is welded to the bottom of the observation window 23 and corresponds to the cutting position.

[0042] Specifically, a sliding block is welded to the side wall of the baffle 25, and springs 26 are provided on both sides of the baffle 25. The two ends of the springs 26 are welded to the sliding block and the inside of the cover 21, respectively.

[0043] Specifically, the splash guard assembly 2 also includes: a slide rail 27, which is connected to the cover 21 by bolts and slidably connected to the second baffle 29; and an adjusting screw 28, which has two opposite threads, which is rotatably connected to the slide rail 27 and threadedly connected to the second baffle 29.

[0044] In this embodiment, the operator observes the cutting operation inside the protective cover 21 through the transparent observation window 23; the scale line 24 is aligned with the cutting position, allowing for a direct assessment of the accuracy of the cutting position of the item to be cut: the cutting process is visualized, facilitating real-time monitoring of the operation status by the operator. Simultaneously, the scale line 24 assists in positioning, improving the accuracy of the cutting position. The first baffle 25 slides along the inner wall of the protective cover 21 via a sliding block. During sliding, the springs 26 on both sides are compressed or stretched, generating a reverse elastic force that acts on the sliding block, causing the first baffle 25 to adhere tightly to the item to be cut. The elastic force of the springs 26 enables the first baffle 25 to self-adjust, allowing it to conform to the sides of items of different sizes, enhancing the clamping effect. Rotating the adjusting screw 28 causes the two opposing threads on the screw to engage with the two second baffles 29, driving them to slide in opposite directions or away from each other along the slide rail 27, adjusting the distance between the two second baffles 29. The adjusting screw 28 precisely controls the movement distance of the second baffles 29, quickly adapting to the limiting requirements of items of different widths, making operation convenient.

[0045] Example 3:

[0046] Specifically, the recycling component 3 also includes: a recycling through hole 31, which is set on the workbench 1 and located above the recycling pipe 32; a guide plate 34, which is welded above the fan 33 and is triangular pyramidal in shape; and multiple ventilation holes 35, which are located on the side wall of the guide plate 34.

[0047] Specifically, the recycling component 3 also includes a door panel 37, which is rotatably connected to the side wall of the collection box 36 and locked to the collection box 36 by a locking pin.

[0048] In this embodiment, the foam scraps generated during cutting are drawn into the recycling pipe 32 through the recycling through-hole 31 on the workbench 1 by the airflow. The fan 33 generates negative pressure airflow, the guide plate 34 guides the airflow and scraps downward, and the ventilation hole 35 balances the air pressure in the pipe to avoid airflow turbulence and form a directional airflow channel. This efficiently guides the foam scraps into the recycling pipe 32, reduces the amount of scraps remaining in the pipe, and improves recycling efficiency. The foam scraps fall into the collection box 36 for storage through the recycling pipe 32. When the scraps in the collection box 36 accumulate to a certain amount, the locking pin is pulled out, and the door panel 37 is opened around the rotating connection to empty and clean the scraps. After cleaning, the door panel 37 is closed, and the locking pin is inserted to lock it, realizing convenient opening and closing of the collection box 36. This facilitates regular cleaning of the foam scraps stored inside, while ensuring the sealing of the collection box 36 in the locked state to prevent scrap leakage.

[0049] In actual use, the operator first places the item to be cut on the workbench 1, then turns the adjusting screw 28 to open the second baffle 29, then lifts the first baffle 25, pushes the item into the protective cover 21, aligns the scale line 24 with the cutting point of the item to be cut, then lowers the first baffle 25, turns the adjusting screw 28 to make the second baffle 29 clamp the item to be cut, and then starts the cutting device through the PLC controller to start cutting. Then the fan 33 is started so that the scrap generated during the cutting process is sucked into the recycling pipe 32 and enters the collection box 36 through the recycling pipe 32. When the cutting is completed, the door panel 37 is opened to take out the scrap in the collection box 36.

[0050] In some other embodiments, one end of the rotating shaft may not be connected to the drive motor, and the connecting shaft may be connected to the rotating wheel. The user can manually control the rotation of the connecting shaft to lower the cutting wheel.

[0051] Fan 33, drive motor one and drive motor two are all electrically connected to the PLC controller. The PLC controller is electrically connected to an external power supply. The PLC controller facilitates the power supply control of the electrical equipment, allowing the equipment to be powered on when needed, thus avoiding the situation where power cannot be supplied when needed.

[0052] It should be noted that the controller can be a conventional known device that is controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific embodiments of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
