Technical Field

[0001] The utility model relates to the technical field of paperboard packaging, in particular to a waste packaging paperboard recycling mechanism. Background Art

[0002] In the prior art, due to the low production cost of packaging paperboard, it is often used for packaging products in various industries, such as packaging paperboard for cosmetics, electronic products, computers and mobile phones, packaging cushioning for mechanical processing products, food packaging, food packaging and beverage product packaging, etc.

[0003] In addition, the recycling of packaging cardboard in the prior art is relatively convenient and the cost is relatively low. When the cardboard is recycled, it is firstly necessary to crush the cardboard through a crushing mechanism, and then clean it to remove dust particles, etc., and then put some chemicals into a pulp machine for stirring to obtain pulp, and then put the pulp into a mold structure to obtain a preliminary cardboard mold. After the cardboard mold is dried, it will produce a certain deformation. Therefore, it is necessary to perform a secondary molding process to press the deformed mold into the shape of the required packaging cardboard, so as to obtain a finished product, which can be used for packaging of various products.

[0004] In the recycling process of the above-mentioned packaging cardboard, corrugated cardboard, corrugated cardboard and other cardboards, after the cardboard is crushed, there are usually a lot of dust particles mixed in the cardboard, and these dust particles need to be removed during cleaning. However, the recycling mechanism in the prior art only performs crushing and then sends it to the cleaning device for dust removal. The whole process is very inconvenient, and the overall steps are increased. In addition, water resources are greatly wasted during the water washing process, which increases costs.

[0005] Therefore, in order to solve the above problems, it is necessary to develop a waste packaging cardboard recycling mechanism with a reasonable structure and improved work quality and efficiency. Utility Model Content

[0027] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0028] Example 1

[0029] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a waste packaging cardboard recycling mechanism comprises a recycling box 1, a feeding port 2 is arranged at the upper end of the recycling box 1, a crushing mechanism is arranged below the feeding port 2, a dust collecting mechanism is arranged below the crushing mechanism, and a discharge port 3 is arranged below the dust collecting mechanism;

[0030] The pulverizing mechanism includes a pulverizing roller 4, through which the discarded packaging cardboard is pulverized; the dust collecting mechanism includes a dust collecting filter 5 arranged at the side wall of the recycling box 1, and an outer shell 6 is arranged around the outer side of the dust collecting filter 5, and the outer shell 6 is fixed at the outer wall of the recycling box 1, and the inner dust collecting filter 5 is covered as a whole;

[0031] The area inside the dust filter 5 is set as the blanking area 7, and the area between the dust filter 5 and the outer shell 6 is set as the dust collection area 8. A vacuum cleaner 9 is also provided outside the recycling box 1. The vacuum cleaner 9 is connected to the dust collection area 8 inside the outer shell 6 through a dust collection pipe 10. When the crushed packaging cardboard falls into the blanking area 7, the dust particles are sucked into the outer shell 6 from the dust filter 5 through the vacuum cleaner 9.

[0032] like Figure 2 As shown, the transverse cross-section of the recovery box 1 is set as a square structure; the feed port 2 at the upper end of the recovery box 1 is set as a trumpet structure; and the discharge port 3 at the lower end of the recovery box 1 is set as a hopper-shaped structure.

[0033] There are four outer shells 6 outside the recycling box 1, and adjacent outer shells 6 are separated by oblique partitions 11; each outer shell 6 is connected and connected with a vacuum cleaner 9.

[0034] A material storage shell 12 is extended from the lower end of each outer shell 6 , and the dust particles sucked into the outer shell 6 fall into the material storage shell 12 accordingly, and a discharge door plate 14 is correspondingly installed on the material storage shell 12 through a hinge assembly 13 .

[0035] like Figure 4 and Figure 5 As shown, there are two layers of crushing mechanism in the recycling box 1, and each layer of the crushing mechanism includes two corresponding crushing rollers 4, and the crushing rollers 4 are provided with corresponding crushing protrusions 16; and the installation direction of the upper and lower layers of crushing rollers 4 is vertical installation, the upper layer crushing rollers 4 are horizontally installed, and the lower layer crushing rollers 4 are vertically installed.

[0036] The specific working principle of this device is as follows: various types of cardboards recycled by this device are put into the box body from the feed port. The pulverizing mechanism is mainly arranged with an upper and lower layer. Each layer is provided with two pulverizing rollers. After being pulverized by the pulverizing rollers of the upper layer, they fall into the pulverizing rollers of the lower layer. Since the pulverizing rollers of the two layers are arranged perpendicular to each other, the pulverizing quality of the cardboard can be increased. At least the cardboard will not stick to each other and will be pulverized thoroughly. Moreover, the pulverizing rollers of the two layers are provided with driving mechanisms (not shown in the figure) correspondingly. Specifically, the pulverizing is driven by the driving mechanism, and the rotation direction of the pulverizing rollers is set accordingly to ensure thorough pulverization.

[0037] The crushed cardboard material falls downward into the material dropping area, and the vacuum cleaner connected to the outer shell generates suction to perform wind suction on the cardboard material falling into the material dropping area. In the above crushing process, dust particles in the cardboard will be squeezed out. When the dust particles fall into the material dropping area, the dust particles are sucked into the dust suction area in the outer shell by suction. Due to the existence of the dust suction filter, the crushed cardboard will not enter the dust suction area. Only some smaller cardboard particles will enter the dust suction area, which will not have a significant impact.

[0038] The crushed paperboard will fall down into the discharge port and be discharged from the discharge port; and the dust particles that fall into the outer dust suction area will fall down into the extended storage shell and then be discharged through the discharge plate, thereby effectively removing these dust particles.

[0039] Example 2

[0040] like Figure 1 and Figure 3 As shown, a waste packaging cardboard recycling mechanism comprises a recycling box 1, a feeding port 2 is arranged at the upper end of the recycling box 1, a crushing mechanism is arranged below the feeding port 2, a dust collecting mechanism is arranged below the crushing mechanism, and a discharge port 3 is arranged below the dust collecting mechanism;

[0041] The pulverizing mechanism includes a pulverizing roller 4, through which the discarded packaging cardboard is pulverized; the dust collecting mechanism includes a dust collecting filter 5 arranged at the side wall of the recycling box 1, and an outer shell 6 is arranged around the outer side of the dust collecting filter 5, and the outer shell 6 is fixed at the outer wall of the recycling box 1, and the inner dust collecting filter 5 is covered as a whole;

[0042] The area inside the dust filter 5 is set as the blanking area 7, and the area between the dust filter 5 and the outer shell 6 is set as the dust collection area 8. A vacuum cleaner 9 is also provided outside the recycling box 1. The vacuum cleaner 9 is connected to the dust collection area 8 inside the outer shell 6 through a dust collection pipe 10. When the crushed packaging cardboard falls into the blanking area 7, the dust particles are sucked into the outer shell 6 from the dust filter 5 through the vacuum cleaner 9.

[0043] like Figure 2 As shown, the transverse cross-section of the recovery box 1 is set as a square structure; the feed port 2 at the upper end of the recovery box 1 is set as a trumpet structure; and the discharge port 3 at the lower end of the recovery box 1 is set as a hopper-shaped structure.

[0044] There are four outer shells 6 outside the recycling box 1, and adjacent outer shells 6 are separated by oblique partitions 11; each outer shell 6 is connected and connected with a vacuum cleaner 9.

[0045] A material storage shell 12 is extended from the lower end of each outer shell 6 , and the dust particles sucked into the outer shell 6 fall into the material storage shell 12 accordingly, and a discharge door plate 14 is correspondingly installed on the material storage shell 12 through a hinge assembly 13 .

[0046] like Figure 4 and Figure 5 As shown, there are two layers of crushing mechanism in the recycling box 1, and each layer of the crushing mechanism includes two corresponding crushing rollers 4, and the crushing rollers 4 are provided with corresponding crushing protrusions 16; and the installation direction of the upper and lower layers of crushing rollers 4 is vertical installation, the upper layer crushing rollers 4 are horizontally installed, and the lower layer crushing rollers 4 are vertically installed.

[0047] like Figure 3 As shown, a blocking rod 15 is also installed in the material dropping area 7, and both ends of the blocking rod 15 are correspondingly fixed on the dust filter 5; the blocking rod 15 is arranged in several layers in the material dropping area 7, and the blocking rods 15 in the same layer are evenly spaced, while the blocking rods 15 adjacent to the upper and lower layers are staggered.

[0048] like Figure 3 As shown, in order to further increase the effect of removing these dust particles, a plurality of layers of material blocking rods are arranged at the position of the material dropping area in the present device, and the upper and lower layers of material blocking rods are arranged in a staggered manner; the purpose of such a design is that if the crushed paperboard material falls directly from above, some dust particles may fall directly downward into the discharge port due to the fast speed, resulting in incomplete absorption of the dust particles; and some dust particles may be mixed between the paperboard materials and discharged from the material dropping port without being absorbed.

[0049] After the device is designed with a material blocking rod, the paperboard falling from above will have its falling time delayed and be blocked by the material blocking rod. On the one hand, dust particles mixed in the paperboard will be shaken out; on the other hand, the dust suction mechanism is given enough time to absorb dust particles, effectively increasing the dust particle removal effect. The structural design is very reasonable and ingenious.
