Description

Technical Field

[0001] The present invention relates to the technical field of plastic recycling and crushing, and more specifically, to a device for recycling and crushing waste materials in the production of environmentally friendly lunch boxes and its usage method. Background Art

[0002] An environmentally friendly lunch box refers to a lunch box that takes environmental protection into consideration in terms of design, materials, and production process. It is usually made of biodegradable materials, such as pulp, corn starch, bamboo, etc. These materials can decompose in the natural environment and will not cause long-term pollution to the ecosystem, being both economical and environmentally friendly.

[0003] Currently, in the production process of environmentally friendly lunch boxes, usually, the raw materials of the lunch boxes are heated and melted and then enter the production equipment. The melted plastic is extruded into thin sheets, which are usually cooled and shaped and then rolled into rolls for subsequent processes. The sheets are sent into a heating device in the production line and evenly heated to a suitable forming temperature. The heated sheets enter a thermoforming machine and are formed into the shape of a lunch box through a mold. The pressure and temperature of the mold are precisely controlled to ensure the size and quality of the lunch box. The formed lunch box is separated from the sheet through an automatic cutting device, and the cutting edge is neat to ensure the beautiful appearance of the lunch box. Then, a crusher is used to crush and recycle the waste materials generated during the production process, converting these originally discarded plastic materials into renewable resources, reducing waste of raw materials, and promoting economic and environmental protection.

[0004] However, currently, the crushing of plastics is usually carried out using a toothed roll crusher. However, if the environmentally friendly lunch box is made of a relatively soft plastic (such as polypropylene), its waste materials are usually relatively soft. During the crushing process by the crusher, due to the relatively soft texture of the waste materials, they are easily stretched by the crushing teeth and wound around the crushing roll. The wound waste materials easily lead to uneven crushing, affecting the quality of the final product, and easily resulting in particles of different sizes. Moreover, it is easy to cause equipment blockage due to winding, resulting in the problem of needing to stop the machine for cleaning, which affects the crushing efficiency. Summary of the Invention

Detailed implementation manners

[0032] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope 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.

[0033] Referring to the accompanying drawings of the specification Figures 1 to 11 , a device for recycling and crushing scraps in the production of environmentally friendly lunch boxes, comprising: a body 1, a frame 11 is arranged on the body 1, a feeding assembly 2 is arranged in the frame 11, a crushing mechanism 3 is arranged in the body 1, the crushing mechanism 3 includes two crushing rollers 31 that can rotate synchronously and in opposite directions, and the feeding assembly 2 is used to convey scraps 100 between the two crushing rollers 31; The crushing roller 31 includes a horizontal shaft 311 and a plurality of crushing teeth 312, and the plurality of crushing teeth 312 are all 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; A plurality of groups of dynamic cutting mechanisms 4 are arranged on the horizontal shaft 311, and the plurality of groups of dynamic cutting mechanisms 4 are respectively arranged between two adjacent crushing teeth 312. The dynamic cutting mechanism 4 includes a plurality of first cutters 41, and the plurality of first cutters 41 are evenly distributed in the circumferential direction of the horizontal shaft 311, and the plurality of first cutters 41 can move linearly along the axial direction of the horizontal shaft 311 on the surface of the horizontal shaft 311. The dynamic cutting mechanism 4 further includes a reciprocating driving assembly 44, and the reciprocating driving assembly 44 is used to drive the plurality of first cutters 41 to reciprocate linearly along the axial direction of the horizontal shaft 311.

[0034] It should be noted that the feeding component 2 is a conveyor belt, which conveys the scraps 100 generated in the process of lunch box production to between the two crushing rollers 31 for crushing. The two crushing rollers 31 can be respectively driven to rotate by a motor, and it is necessary to ensure that the rotation directions of the two crushing rollers 31 are opposite and the rotation speeds are the same to ensure the crushing effect on the scraps 100. The reciprocating driving component 44 can be driven by a cylinder, and the cylinder drives a plurality of first cutting knives 41 to reciprocate linearly, so that during the crushing process of the scraps 100, the first cutting knives 41 that can move linearly along the axial direction of the cross shaft 311 reciprocate linearly to cut the scraps 100 wound around the cross shaft 311.

[0035] The specific implementation scenario is as follows: First, the conveyor belt conveys the scraps 100 generated in the process of lunch box production to between the two crushing rollers 31 for crushing. During the crushing process of the scraps 100, the reciprocating driving component 44 drives a plurality of first cutting knives 41 between two adjacent crushing teeth 312 to reciprocate linearly between two adjacent crushing teeth 312, so that the scraps 100 wound around the cross shaft 311 can be cut by the plurality of first cutting knives 41, thereby solving the problem that the scraps 100 are easily wound around the cross shaft 311 due to the soft material of the scraps 100 during the crushing process, resulting in equipment blockage and affecting the crushing efficiency and production continuity.

[0036] It should also be noted that by crushing and recycling the scraps 100 generated in the process of plastic lunch box production, these originally discarded plastic materials can be converted into renewable resources, reducing raw material waste. At the same time, it can significantly reduce the waste discharge during the production process, reduce the burden on the environment, and the crushing and recycling of the scraps 100 can also reduce production costs, which is economical and environmentally friendly.

[0037] Further, referring to the attached drawings of the specification Figures 4 to 6 The dynamic cutting mechanism 4 further includes a plurality of annular grooves 42 opened on the surface of the cross shaft 311. The annular grooves 42 are opened between two adjacent crushing teeth 312. A sliding ring 43 is slidably arranged on the annular grooves 42, and a plurality of first cutting knives 41 are fixedly arranged on the sliding ring 43.

[0038] It should be noted that by setting the slidable sliding ring 43 and fixedly arranging a plurality of first cutting knives 41 on the sliding ring 43, the plurality of first cutting knives 41 can be driven to move synchronously by driving the sliding ring 43 to slide, achieving the effect of cutting the wound scraps 100.

[0039] It should also be noted that a plurality of stoppers are fixedly arranged between two adjacent crushing teeth 312, and the plurality of stoppers are evenly distributed in the circumferential direction of the horizontal shaft 311, and the gap between two adjacent stoppers is slightly larger than the thickness of the first cutter 41. Thus, during the crushing process, the entangled scraps 100 can be prevented from winding in the annular groove 42 by the blocking of the stoppers. By arranging a plurality of stoppers, the entangled scraps 100 can be located on the plurality of stoppers, avoiding the problem of interference caused by the entangled scraps 100 in the annular groove 42 when the sliding ring 43 slides in the annular groove 42.

[0040] Further, referring to the attached drawings of the specification Figure 6 and Figure 7 , the reciprocating drive assembly 44 includes a through port 441 formed in the annular groove 42. A fixing rod 442 is fixedly arranged on the inner side of the sliding ring 43. The fixing rod 442 is slidably arranged in the through port 441, and a sliding shaft 443 is slidably arranged in the horizontal shaft 311. One end of the fixing rod 442 away from the sliding ring 43 is installed on the sliding ring 43. One end of the sliding shaft 443 extends outside the horizontal shaft 311 and is fixedly installed with an inclined surface frustum 444. One side of the machine body 1 is fixedly installed with a fixing shaft 445. One end of the fixing shaft 445 is movably abutted against the inclined surface of the inclined surface frustum 444, and 446 is fixedly arranged on the inclined surface frustum 444. One end of 446 away from the inclined surface frustum 444 is fixedly arranged at the end of the horizontal shaft 311.

[0041] It should be noted that the fixing rod 442 can be fixedly arranged on or inserted into the sliding shaft 443. When driving the horizontal shaft 311 to rotate, the sliding shaft 443 can be driven to move synchronously. That is, under the joint cooperation of the inclined surface frustum 444 and the fixing shaft 445, the sliding shaft 443 can be driven to perform a reciprocating linear motion in the horizontal shaft 311. Thus, when the sliding shaft 443 performs a reciprocating linear motion, the sliding ring 43 is driven to perform a reciprocating linear motion through the fixing rod 442, so that the plurality of first cutters 41 cut the scraps 100 wound on the horizontal shaft 311 during the reciprocating linear motion process, thereby solving the problem that the soft material of the scraps 100 easily causes the scraps 100 to wind on the horizontal shaft 311, resulting in equipment blockage and affecting the crushing efficiency and production continuity.

[0042] Further, referring to the attached drawings of the specification Figures 6 to 9 , an air supply mechanism 5 is further arranged on the inclined surface frustum 444. The air supply mechanism 5 includes a plurality of diversion seats 51 fixedly arranged on the inclined surface frustum 444. A plurality of diversion holes 52 are formed in the inclined surface frustum 444. The air inlet ends of the plurality of diversion holes 52 are communicated with the corresponding diversion seats 51. A transverse hole 53 is formed in the sliding shaft 443. The air outlet ends of the plurality of diversion holes 52 are all communicated with the transverse hole 53. A plurality of vertical holes 54 are formed in the sliding shaft 443. The plurality of vertical holes 54 are communicated with the corresponding through ports 441.

[0043] It should be noted that during the rotation of the reciprocating drive assembly 44, the airflow is guided by a plurality of flow guiding seats 51 to pass through the plurality of flow guiding seats 51 and the flow guiding holes 52 into the transverse holes 53, and the airflow flows in the transverse holes 53. When the airflow flows through the plurality of vertical holes 54, it flows out from the plurality of vertical holes 54 and enters between two adjacent crushing teeth 312 through the corresponding through ports 441, so that the airflow entering between the two adjacent crushing teeth 312 helps to dissipate heat, preventing the plastic material from softening due to the heat generated during crushing, thereby maintaining the stability of the crushing process and the product quality.

[0044] It should also be noted that when the airflow enters between two adjacent crushing teeth 312, when the scrap 100 is about to wind around the transverse shaft 311, the fluidity of the material can be improved by the blowing of the airflow, so as to further reduce the winding during the crushing process, promote a more uniform crushing effect, and the flow of the airflow through between two adjacent crushing teeth 312 can accelerate the movement of the scrap 100 and improve the crushing efficiency.

[0045] It should be further noted that when the airflow blows between two adjacent crushing teeth 312, the airflow can be blown towards the crushed plastic particles to prevent the aggregation of the particles after crushing, making the particle shape of the final crushed product more uniform and ensuring its crushing effect.

[0046] In the above technical solution, by setting the dynamic cutting mechanism 4 during the crushing process of the scrap 100, the material winding during the crushing process is reduced, and by setting the air supply mechanism 5 to supply airflow between two adjacent crushing teeth 312, it plays an auxiliary role in heat dissipation, preventing the plastic material from softening due to the heat generated during crushing, maintaining the stability of the crushing process and the product quality, and further playing the role of reducing winding. However, during the production process of lunch boxes, the raw materials of lunch boxes are usually heated and melted and then enter the production equipment. The molten plastic is extruded into thin sheets, and these sheets are usually cooled and shaped and then rolled into rolls for subsequent processes. And the sheets are sent into a heating device in the production line and uniformly heated to a suitable forming temperature. The heated sheets enter a thermoforming machine and are formed into the shape of a lunch box through a mold. The pressure and temperature of the mold are precisely controlled to ensure the size and quality of the lunch box. The formed lunch box is separated from the sheet by an automatic cutting device, as Figure 11 shown. At this time, the scrap 100 is in a perforated shape. During the crushing process, due to the presence of a plurality of circular holes on the scrap 100, the crushing teeth 312 will have empty bites in the hole areas during biting, resulting in uneven distribution of the biting force, and some areas cannot be fully crushed. The sizes of the crushed particles are uneven, or there are large residual pieces, which affect the subsequent recycling.

[0047] It should also be noted that "empty biting" refers to the problem that during the crushing process, due to the presence of circular holes or voids on the scrap material 100, the crushing teeth 312 cannot contact the material in these areas, resulting in the invalidity of the biting action of the crushing teeth 312.

[0048] Specifically, referring to the attached drawings of the specification Figure 10 , a material distributing mechanism 6 is further provided on the machine body 1. The material distributing mechanism 6 includes a second cutting knife 62 capable of linear vertical movement. The second cutting knife 62 cuts the conveyed scrap material 100 through linear vertical movement, including a first linear driving assembly 61. The first linear driving assembly 61 is installed on the frame 11. The second cutting knife 62 is fixedly installed at the output end of the first linear driving assembly 61. A material receiving plate 63 is fixedly arranged in the frame 11, and the material receiving plate 63 is horizontally arranged. The material receiving plate 63 is used to receive the cut scrap material 100. A material pushing assembly 64 is arranged on the frame 11. The material pushing assembly 64 is used to push the scrap material 100 on the material receiving plate 63 away from the material receiving plate 63. An inclined guide plate 65 is fixedly arranged in the frame 11. The guide plate 65 is used to guide the scrap material 100 pushed away from the material receiving plate 63 between the two crushing rollers 31. The material pushing assembly 64 includes a second linear driving assembly 641 fixedly arranged on the frame 11. A pushing plate 642 is fixedly installed at the output end of the second linear driving assembly 641. The pushing plate 642 is slidably arranged on the material receiving plate 63.

[0049] It should be noted that both the first linear driving assembly 61 and the second linear driving assembly 641 can be cylinders. During feeding, the feeding assembly 2 is used for feeding. During the feeding process, one end of the scrap material 100 vertically falls onto the material receiving plate 63, and one end of the scrap material 100 is stacked on the material receiving plate 63. At this time, the first linear driving assembly 61 can be used to drive the second cutting knife 62 to move vertically downward and cut the scrap material 100, so that the cut scrap material 100 can be directly stacked on the material receiving plate 63. Then, the second linear driving assembly 641 drives the pushing plate 642 to move and push the stacked scrap material 100 to fall between the two crushing rollers 31 through the guidance of the pushing plate 642 for crushing. During the crushing process, since the scrap material 100 falls between the two crushing rollers 31 in a stacked state, during the crushing process, due to the stacking of the scrap material 100, the holes on the scrap material 100 can be covered, so that during the crushing process, the phenomenon of "empty biting" caused by the crushing teeth 312 directly passing through the holes on the scrap material 100 and tearing the scrap material 100 can be reduced, ensuring the crushing effect of the scrap material 100.

[0050] Furthermore, referring to the attached drawings of the specification Figures 1 to 3 , the crushing mechanism 3 further includes a driving component 32. The output end of the driving component 32 is fixedly connected to one of the crushing rollers 31. Gears 33 are fixedly installed at one ends of the two crushing rollers 31, and the two gears 33 are meshed with each other.

[0051] It should be noted that the driving component 32 is a motor. The output end of the driving component 32 can be connected to one of the crushing rollers 31 through belt drive, so that it can drive one of the crushing rollers 31 to rotate, and through the meshing drive of the two gears 33, the two crushing rollers 31 can rotate simultaneously to perform crushing operation on the scraps 100.

[0052] Refer to the attached Figure 12 For the usage method of a device for recycling and crushing scraps in the production of environmentally friendly lunch boxes, it includes the following steps: Step 1: Convey the scraps 100 in the lunch box production process to the machine body 1 through the feeding component 2; Step 2: During the conveying process, cut the scraps 100 through the material distribution mechanism 6, stack the cut parts, and push the stacked scraps 100 onto the crushing mechanism 3 for crushing; Step 3: During the crushing process, drive the cutter 41 to reciprocate between two adjacent crushing teeth 312 through the dynamic cutting mechanism 4 to cut the scraps 100 wound around the crushing roller 31; Step 4: During the crushing process, convey air flow between two adjacent crushing teeth 312 on the crushing roller 31 through the air supply mechanism 5; Step 5: Collect the crushed scraps 100.

[0053] The implementation scenario is specifically as follows: Feed through the feeding component 2, and during the feeding process, make one end of the scraps 100 vertically fall onto the receiving plate 63, so that one end of the scraps 100 is stacked on the receiving plate 63. At this time, the cutter 62 can be driven to move vertically downward by the linear driving component 61 to cut the scraps 100, so that the cut scraps 100 can be directly stacked on the receiving plate 63. Then, drive the push plate 642 to move through the linear driving component 641 to push the stacked scraps 100 to fall between the two crushing rollers 31 through the guidance of the push plate 642 for crushing. During the crushing process, make the scraps 100 fall between the two crushing rollers 31 in a stacked state, drive one of the crushing rollers 31 to rotate at the same time, and through the meshing drive of the two gears 33, the two crushing rollers 31 can rotate simultaneously, so as to perform crushing operation on the scraps 100 that fall between the two crushing rollers 31 in a stacked state. During the crushing process, drive multiple cutters 41 to reciprocate between two adjacent crushing teeth 312 through the reciprocating driving component 44 to cut the wound scraps 100, solving the problem that winding is easy to cause equipment blockage and affect the crushing efficiency and production continuity. During the crushing process, convey air flow between two adjacent crushing teeth 312 through the air supply mechanism 5 to help dissipate heat and prevent the plastic material from softening due to the heat generated during crushing, thereby maintaining the stability of the crushing process and the crushing quality.

[0054] The above embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
