Description

Technical Field

[0001] This invention relates to the field of plastic recycling and crushing technology, and more specifically, to a device for recycling and crushing scrap materials in the production of environmentally friendly lunch boxes and its usage method. Background Technology

[0002] Eco-friendly lunch boxes refer to those lunch boxes that take environmental protection into account in their design, materials, and production processes. They are usually made of biodegradable materials such as pulp, corn starch, and bamboo, which can decompose in the natural environment and will not cause long-term pollution to the ecology, making them economical and environmentally friendly.

[0003] Currently, the production process of environmentally friendly lunch boxes typically involves melting the raw materials and feeding them into production equipment. The molten plastic is extruded into thin sheets, which are then cooled, shaped, and rolled up for subsequent processes. The sheets are fed into a heating device on the production line and heated evenly to a suitable forming temperature. The heated sheets then enter a thermoforming machine, where they are molded into the shape of the lunch box. The pressure and temperature of the mold are precisely controlled to ensure the size and quality of the lunch box. After forming, the lunch box is separated from the sheet by an automatic cutting device, ensuring clean edges and an aesthetically pleasing appearance. The scraps generated during production are then crushed and recycled, transforming previously discarded plastic materials into renewable resources, reducing waste, and promoting economic and environmental protection.

[0004] However, currently, plastics are usually crushed using toothed roller crushers. But if the eco-friendly lunch boxes are made of softer plastics (such as polypropylene), the scraps are usually soft. During the crushing process, because the scraps are soft, they are easily stretched and wrapped around the crushing rollers by the crushing teeth. The wrapped scraps can easily lead to uneven crushing, affecting the quality of the final product, resulting in particles of different sizes. Furthermore, the entanglement can easily cause equipment blockage, requiring machine shutdown for cleaning, thus affecting crushing efficiency. Summary of the Invention

[0005] The present invention provides a device and method for recycling and crushing scrap materials in the production of environmentally friendly lunch boxes. The problem to be solved is that in the process of crushing soft scrap materials, the existing crushers are prone to stretching and wrapping the scrap materials on the crushing roller by the crushing teeth. The wrapped scrap materials can easily lead to uneven crushing, affecting the quality of the final product, and can easily produce particles of different sizes. Furthermore, the wrapping can easily cause equipment blockage, resulting in the need to stop the machine for cleaning, thus affecting the crushing efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for recycling and crushing scrap materials in the production of environmentally friendly lunch boxes, comprising: a machine body, a frame on the machine body, a feeding component inside the frame, a crushing mechanism inside the machine body, the crushing mechanism including two crushing rollers that can rotate synchronously in opposite directions, and the feeding component for conveying scrap materials between the two crushing rollers.

[0007] The crushing roller includes a horizontal shaft and multiple crushing teeth. The multiple crushing teeth are fixedly arranged on the horizontal shaft and are arranged in a linear array on the horizontal shaft.

[0008] Multiple sets of dynamic cutting mechanisms are provided on the horizontal axis. The multiple sets of dynamic cutting mechanisms are respectively arranged between two adjacent crushing teeth. The dynamic cutting mechanism includes multiple cutters, which are evenly distributed in the circumferential direction of the horizontal axis. The dynamic cutting mechanism also includes a reciprocating drive assembly, which is used to drive the multiple cutters to reciprocate linearly along the axial direction of the horizontal axis.

[0009] In a preferred embodiment, the dynamic cutting mechanism further includes a plurality of annular grooves formed on the surface of the horizontal shaft. The annular grooves are formed between two adjacent crushing teeth, and a sliding ring is slidably disposed on the annular groove. A plurality of cutters are fixedly disposed on the sliding ring.

[0010] In a preferred embodiment, a plurality of stops are fixedly arranged between two adjacent crushing teeth, and the plurality of stops are evenly distributed in the circumferential direction of the horizontal axis, and the gap between two adjacent stops is greater than the thickness of the first cutter.

[0011] In a preferred embodiment, the reciprocating drive assembly includes a through-hole formed in an annular groove, a fixed rod fixedly disposed on the inner side of the sliding ring, the fixed rod being slidably disposed in the through-hole, and a sliding shaft being slidably disposed in the horizontal shaft, the end of the fixed rod away from the sliding ring being mounted on the sliding shaft, one end of the sliding shaft extending out of the horizontal shaft and being fixedly mounted on an inclined frustum, and a fixed shaft fixedly disposed on one side of the machine body, one end of the fixed shaft being movably abutting against the inclined surface of the inclined frustum.

[0012] In a preferred embodiment, an air supply mechanism is further provided on the inclined circular platform. The air supply mechanism includes multiple guide seats fixedly disposed on the inclined circular platform. Multiple guide holes are opened on the inclined circular platform. The air inlet end of the multiple guide holes is connected to the corresponding guide seat. A horizontal hole is opened in the sliding shaft. The air outlet end of the multiple guide holes is connected to the horizontal hole. Multiple vertical holes are opened on the sliding shaft. The multiple vertical holes are connected to the corresponding outlet.

[0013] In a preferred embodiment, the machine body is further provided with a material distribution mechanism, which includes a second cutter capable of vertical linear motion. The second cutter cuts the conveyed scrap material through vertical linear motion. A receiving plate is fixedly provided inside the frame, and the receiving plate is horizontally arranged. The receiving plate is used to collect the cut scrap material. A pushing component is provided on the frame, which is used to push the scrap material on the receiving plate away from the receiving plate. An inclined guide plate is fixedly provided inside the frame, which is used to guide the scrap material pushed away from the receiving plate to between the two crushing rollers.

[0014] In a preferred embodiment, the material distribution mechanism includes a linear drive assembly 1, which is mounted on a frame, and a cutter 2 is fixedly mounted on the output end of the linear drive assembly 1.

[0015] In a preferred embodiment, the pushing assembly includes a linear drive assembly two fixedly mounted on the frame, and a push plate is fixedly mounted on the output end of the linear drive assembly two, with the push plate slidably mounted on the receiving plate.

[0016] In a preferred embodiment, the crushing mechanism further includes a drive assembly, the output end of which is fixedly connected to one of the crushing rollers, and a gear is fixedly mounted on one end of each of the two crushing rollers, with the two gears meshing with each other.

[0017] A method for using a device for recycling and crushing scrap materials in the production of environmentally friendly lunch boxes includes the following steps:

[0018] Step 1: The scraps from the lunchbox production process are conveyed onto the machine body via the feeding assembly;

[0019] Step 2: During the conveying process, the scrap material is cut by the material distribution mechanism, the cut parts are stacked, and the stacked scrap material is pushed to the crushing mechanism for crushing.

[0020] Step 3: During the crushing process, the dynamic cutting mechanism drives the cutter to reciprocate between two adjacent crushing teeth to cut off the scrap material wrapped around the crushing roller.

[0021] Step 4: During the crushing process, airflow is delivered between two adjacent crushing teeth on the crushing roller through the air supply mechanism;

[0022] Step 5: Collect the scraps after crushing.

[0023] The beneficial effects of this invention are as follows:

[0024] This invention, by setting up a dynamic cutting structure, cuts off the tangled scraps during the crushing process using a cutter that can reciprocate linearly along the crushing roller axis, preventing them from continuing to entangle on the crushing roller and thus maintaining the normal operation of the equipment. This achieves the recycling and reuse of scraps generated during the production of environmentally friendly lunch boxes, reducing resource waste and being both economical and environmentally friendly.

[0025] This invention, by setting up an air supply mechanism, can deliver airflow between two adjacent crushing teeth on the crushing roller during the crushing process, which helps dissipate heat and prevents the plastic material from softening due to the heat generated during crushing, thereby maintaining the stability of the crushing process and the product quality.

[0026] This invention, by setting up a material distribution mechanism, cuts and stacks scrap materials, and then sends the stacked scrap materials between two crushing rollers for crushing. This allows the stacked scrap materials to cover the holes on the scrap materials, thereby reducing the phenomenon of the crushing teeth directly passing through the holes on the scrap materials and tearing the scrap materials during the crushing process, thus ensuring the crushing effect of the scrap materials.

Detailed Implementation

[0040] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0041] Refer to the instruction manual appendix Figures 1 to 11 An environmentally friendly lunch box production recycling and crushing device includes: a machine body 1, a frame 11 on the machine body 1, a feeding component 2 inside the frame 11, and a crushing mechanism 3 inside the machine body 1. The crushing mechanism 3 includes two crushing rollers 31 that can rotate synchronously in opposite directions. The feeding component 2 is used to convey scrap 100 between the two crushing rollers 31.

[0042] The crushing roller 31 includes a horizontal shaft 311 and a plurality of crushing teeth 312. The plurality of crushing teeth 312 are fixedly arranged on the horizontal shaft 311, and the plurality of crushing teeth 312 are arranged in a linear array on the horizontal shaft 311.

[0043] Multiple sets of dynamic cutting mechanisms 4 are provided on the horizontal shaft 311. The multiple sets of dynamic cutting mechanisms 4 are respectively arranged between two adjacent crushing teeth 312. The dynamic cutting mechanism 4 includes multiple cutters 41. The multiple cutters 41 are evenly distributed in the circumferential direction of the horizontal shaft 311, and the multiple cutters 41 can move linearly along the surface of the horizontal shaft 311 in the axial direction of the horizontal shaft 311. The dynamic cutting mechanism 4 also includes a reciprocating drive assembly 44, which is used to drive the multiple cutters 41 to reciprocate linearly in the axial direction of the horizontal shaft 311.

[0044] It should be noted that the feeding component 2 is a conveyor belt, which transports the scrap material 100 generated during the production of the lunch box to the space between two crushing rollers 31 for crushing. The two crushing rollers 31 can be driven to rotate by a motor, and it is necessary to ensure that the two crushing rollers 31 rotate in opposite directions and at the same speed to ensure the crushing effect on the scrap material 100. The reciprocating drive component 44 can be driven by a cylinder, which drives multiple cutters 41 to reciprocate linearly. During the crushing process of the scrap material 100, the cutters 41 on the horizontal shaft 311, which can move linearly along the axial direction of the horizontal shaft 311, reciprocate linearly to cut the scrap material 100 wrapped on the horizontal shaft 311.

[0045] The specific implementation scenario is as follows: First, the scrap material 100 generated during the production of lunch boxes is conveyed by a conveyor belt to the space between two crushing rollers 31 for crushing. During the crushing process of the scrap material 100, the reciprocating drive assembly 44 drives multiple cutters 41 between two adjacent crushing teeth 312 to reciprocate linearly between the two adjacent crushing teeth 312. This allows the scrap material 100 wrapped around the horizontal shaft 311 to be cut off by the multiple cutters 41. In this way, the problem that the soft material of the scrap material 100 can easily wrap around the horizontal shaft 311, causing equipment blockage and affecting crushing efficiency and production continuity can be solved during the crushing process.

[0046] It should also be noted that by crushing and reusing the scraps 100 generated during the production of plastic lunch boxes, these originally discarded plastic materials can be transformed into renewable resources, reducing raw material waste. At the same time, it can significantly reduce waste emissions during the production process, lessen the burden on the environment, and the crushing and reuse of scraps 100 can also reduce production costs, making it economical and environmentally friendly.

[0047] Further, please refer to the appendix to the instruction manual. Figures 4 to 6 The dynamic cutting mechanism 4 also includes multiple annular grooves 42 formed on the surface of the horizontal shaft 311. The annular grooves 42 are formed between two adjacent crushing teeth 312. A sliding ring 43 is slidably arranged on the annular grooves 42, and multiple cutters 41 are fixedly arranged on the sliding ring 43.

[0048] It should be noted that by setting a sliding ring 43 and fixing multiple cutters 41 on the sliding ring 43, the sliding ring 43 can be driven to move multiple cutters 41 synchronously, thereby achieving the effect of cutting the wrapped scrap material 100.

[0049] It should also be noted that multiple baffles are fixedly arranged between two adjacent crushing teeth 312, and the multiple baffles are evenly distributed in the circumferential direction of the horizontal axis 311. The gap between two adjacent baffles is slightly larger than the thickness of the cutter 41. Thus, during the crushing process, the baffles can prevent the entangled scrap material 100 from getting tangled in the annular groove 42. By setting multiple baffles, the entangled scrap material 100 can be located on multiple baffles, avoiding interference caused by the entangled scrap material 100 being in the annular groove 42 when the sliding ring 43 slides in the annular groove 42.

[0050] Further, please refer to the appendix to the instruction manual. Figure 6 and Figure 7 The reciprocating drive assembly 44 includes a through-hole 441 formed in the annular groove 42. A fixing rod 442 is fixedly provided on the inner side of the sliding ring 43. The fixing rod 442 is slidably provided in the through-hole 441. A sliding shaft 443 is slidably provided in the horizontal shaft 311. One end of the fixing rod 442 away from the sliding ring 43 is installed on the sliding shaft 443. One end of the sliding shaft 443 extends out of the horizontal shaft 311 and is fixedly installed on an inclined frustum 444. A fixing shaft 445 is fixedly installed on one side of the machine body 1. One end of the fixing shaft 445 is movably abutting against the inclined surface of the inclined frustum 444. A 446 is fixedly provided on the inclined frustum 444. One end of the 446 away from the inclined frustum 444 is fixedly provided at the end of the horizontal shaft 311.

[0051] It should be noted that the fixing rod 442 can be fixedly mounted on the sliding shaft 443 or inserted into the sliding shaft 443. When the horizontal shaft 311 is driven to rotate, it can drive the sliding shaft 443 to move synchronously. With the cooperation of the inclined frustum 444 and the fixing shaft 445, it can drive the sliding shaft 443 to reciprocate linearly within the horizontal shaft 311. Thus, when the sliding shaft 443 reciprocates linearly, the fixing rod 442 drives the sliding ring 43 to reciprocate linearly. During the reciprocating linear motion, the multiple cutters 41 cut the scrap material 100 wrapped around the horizontal shaft 311. This solves the problem that the soft material of the scrap material 100 easily wraps around the horizontal shaft 311, causing equipment blockage and affecting crushing efficiency and production continuity.

[0052] Further, please refer to the appendix to the instruction manual. Figures 6 to 9 An air supply mechanism 5 is also provided on the inclined frustum 444. The air supply mechanism 5 includes multiple guide seats 51 fixedly installed on the inclined frustum 444. Multiple guide holes 52 are opened on the inclined frustum 444. The air inlet end of the multiple guide holes 52 is connected to the corresponding guide seat 51. A horizontal hole 53 is opened in the sliding shaft 443. The air outlet end of the multiple guide holes 52 is connected to the horizontal hole 53. Multiple vertical holes 54 are opened on the sliding shaft 443. The multiple vertical holes 54 are connected to the corresponding outlet 441.

[0053] It should be noted that during the rotation of the reciprocating drive assembly 44, the airflow is guided by multiple guide seats 51 through multiple guide seats 51 and guide holes 52 into the horizontal hole 53, and the airflow flows in the horizontal hole 53. When the airflow flows through multiple vertical holes 54, it flows out from multiple vertical holes 54 and enters between two adjacent crushing teeth 312 through the corresponding through-holes 441. The airflow entering between two adjacent crushing teeth 312 helps to dissipate heat and prevent the plastic material from softening due to the heat generated by crushing, thereby maintaining the stability of the crushing process and the product quality.

[0054] It should also be noted that when the airflow enters between two adjacent crushing teeth 312, the flowability of the material can be improved by blowing it when the scrap material 100 is about to wrap around the horizontal shaft 311. This can further reduce the wrapping during the crushing process and promote a more uniform crushing effect. Furthermore, the flow of the airflow between two adjacent crushing teeth 312 can accelerate the movement of the scrap material 100 and improve the crushing efficiency.

[0055] It should also be noted that when the airflow blows between two adjacent crushing teeth 312, it can direct the airflow towards the crushed plastic particles, preventing the particles from agglomerating and making the final crushed product more uniform in shape, thus ensuring its crushing effect.

[0056] In the above technical solution, a dynamic cutting mechanism 4 is set up during the crushing of scrap material 100 to reduce material entanglement during the crushing process. An air supply mechanism 5 is set up to deliver airflow between two adjacent crushing teeth 312 to assist in heat dissipation, preventing the plastic material from softening due to heat generated during crushing, maintaining the stability of the crushing process and product quality, and further reducing entanglement. However, in the lunchbox production process, the raw materials for the lunchbox are usually heated and melted before entering the production equipment. The molten plastic is extruded into thin sheets. These sheets are usually cooled and shaped before being rolled into rolls for subsequent processes. The sheets are fed into a heating device on the production line and uniformly heated to a suitable forming temperature. The heated sheets then enter a thermoforming machine and are molded into the shape of a lunchbox. The pressure and temperature of the mold are precisely controlled to ensure the size and quality of the lunchbox. After molding, the lunchbox is separated from the sheets by an automatic cutting device. Figure 11 As shown, the scrap material 100 is perforated. During the crushing process, because the scrap material 100 has multiple circular holes, the crushing teeth 312 will bite into the hole area when they bite, resulting in uneven distribution of biting force. Some areas cannot be fully crushed, and the crushed particles are uneven in size or large fragments appear, which affects subsequent recycling.

[0057] It should also be noted that "empty bite" refers to the problem that during the crushing process, due to the presence of circular holes or gaps on the scrap material 100, the crushing teeth 312 cannot contact the material in these areas, resulting in the ineffective biting action of the crushing teeth 312.

[0058] For details, please refer to the instruction manual appendix. Figure 10 The machine body 1 is also equipped with a material distribution mechanism 6, which includes a second cutter 62 capable of vertical linear motion. The second cutter 62 cuts the conveyed scrap material 100 through vertical linear motion. It also includes a linear drive assembly 61, which is mounted on the frame 11. The second cutter 62 is fixedly mounted on the output end of the linear drive assembly 61. A receiving plate 63 is fixedly installed inside the frame 11, and the receiving plate 63 is horizontally positioned. The receiving plate 63 is used to collect the cut scrap material 100. The frame 11... A pushing component 64 is provided on the upper part, which is used to push the scrap material 100 on the receiving plate 63 away from the receiving plate 63. An inclined guide plate 65 is fixedly provided inside the frame 11, which is used to guide the scrap material 100 pushed away from the receiving plate 63 to between the two crushing rollers 31. The pushing component 64 includes a linear drive component 641 fixedly provided on the frame 11. A push plate 642 is fixedly installed at the output end of the linear drive component 641, and the push plate 642 is slidably provided on the receiving plate 63.

[0059] It should be noted that both linear drive assembly 61 and linear drive assembly 641 can be cylinders. During feeding, the material is fed by the feeding assembly 2, and during the feeding process, one end of the scrap material 100 falls vertically onto the receiving plate 63, causing one end of the scrap material 100 to stack on the receiving plate 63. At this time, the linear drive assembly 61 can drive the cutter 62 to move vertically downward and cut the scrap material 100, so that the cut scrap material 100 can be directly stacked on the receiving plate 63. Then, the linear drive assembly 641 drives the pusher... The moving plate 642 pushes the stacked scrap material 100 to fall between the two crushing rollers 31 for crushing. During the crushing process, since the scrap material 100 falls between the two crushing rollers 31 in a stacked state, the stacking of the scrap material 100 can cover the holes on the scrap material 100. This reduces the phenomenon of the crushing teeth 312 directly passing through the holes on the scrap material 100 and tearing the scrap material 100, thus ensuring the crushing effect of the scrap material 100.

[0060] Further, please refer to the appendix to the instruction manual. Figures 1 to 3 The crushing mechanism 3 also includes a drive component 32. The output end of the drive component 32 is fixedly connected to one of the crushing rollers 31. A gear 33 is fixedly installed at one end of each of the two crushing rollers 31, and the two gears 33 mesh with each other.

[0061] It should be noted that the drive component 32 is a motor. The output end of the drive component 32 can be connected to one of the crushing rollers 31 via belt drive, so that it can drive one of the crushing rollers 31 to rotate, and through the meshing of two gears 33, the two crushing rollers 31 can rotate simultaneously to crush the scrap material 100.

[0062] Refer to the instruction manual appendix Figure 12 A method for using a recycling and shredding device in the production of environmentally friendly lunch boxes includes the following steps:

[0063] Step 1: The scrap material 100 from the lunch box production process is conveyed onto the machine body 1 through the feeding component 2;

[0064] Step 2: During the conveying process, the scrap material 100 is cut by the material distribution mechanism 6, the cut parts are stacked, and the stacked scrap material 100 is pushed onto the crushing mechanism 3 for crushing.

[0065] Step 3: During the crushing process, the dynamic cutting mechanism 4 drives the cutter 41 to reciprocate between two adjacent crushing teeth 312 to cut off the scrap material 100 wrapped on the crushing roller 31.

[0066] Step 4: During the crushing process, airflow is delivered between two adjacent crushing teeth 312 on the crushing roller 31 through the air supply mechanism 5;

[0067] Step 5: Collect the 100 pieces of shredded scrap.

[0068] The specific implementation scenario is as follows: Feeding is performed via the feeding assembly 2. During the feeding process, one end of the scrap material 100 falls vertically onto the receiving plate 63, causing it to stack on the receiving plate 63. At this time, the linear drive assembly 61 drives the cutter 62 to move vertically downwards and cut the scrap material 100, allowing the cut scrap material 100 to be directly stacked on the receiving plate 63. Then, the linear drive assembly 641 drives the pusher plate 642 to move, pushing the stacked scrap material 100 through the guide of the pusher plate 642 into the space between the two crushing rollers 31 for crushing. During the crushing process, the scrap material 100, in its stacked state, falls between the two crushing rollers 31, while simultaneously driving one of the rollers... The two crushing rollers 31 rotate and are driven by the meshing of two gears 33, so that the two crushing rollers 31 can rotate simultaneously. The scrap material 100 falling between the two crushing rollers 31 in a stacked state is crushed. During the crushing process, the reciprocating drive assembly 44 drives multiple cutters 41 to reciprocate between two adjacent crushing teeth 312 to cut off the tangled scrap material 100. This solves the problem that tangling can easily cause equipment blockage, which affects crushing efficiency and production continuity. During the crushing process, the air supply mechanism 5 delivers airflow between two adjacent crushing teeth 312 to help dissipate heat and prevent the plastic material from softening due to the heat generated during crushing, thereby maintaining the stability and crushing quality of the crushing process.

[0069] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
