Description

Technical Field

[0001] The utility model relates to the technical field of treatment of waste plastics from household appliances, in particular to a crushing and conveying device for processing waste plastics from household appliances. Background Art

[0002] Waste plastics from household appliances refer to various plastic parts contained in discarded household appliances. Common waste plastics from household appliances include plastics used in the shells and internal structural parts of household appliances such as televisions, refrigerators, washing machines, and air conditioners. With the replacement and scrapping of household appliances, a large amount of waste plastics from household appliances will be generated. Reasonable recycling and treatment of them can not only reduce environmental pollution, but also realize the reuse of resources, which has important environmental and economic significance.

[0003] Since household appliances will form a huge number of plastic sheets or particles after being crushed, however, in terms of the current actual situation, the existing household appliance plastics that have been crushed are very likely to have a disturbing accumulation situation during the specific process of feeding, and this accumulation situation is difficult to be effectively improved, and it is impossible to achieve a good dispersed feeding effect, which in turn has a great adverse effect on the subsequent screening efficiency and screening effect, resulting in the ultimate failure to achieve the expected ideal screening state.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0005] The utility model aims to provide a crushing and conveying device for processing waste plastics of household appliances, which is used to solve the problem that the existing crushed household appliance plastics are prone to accumulation during the feeding process, thereby affecting the subsequent screening efficiency and screening effect.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A crushing and conveying device for processing waste plastics from household appliances comprises a frame, a cover shell is fixedly connected to the top of the frame, a crushing roller is arranged inside the cover shell, a discharging frame is arranged at the bottom of the cover shell, a conveyor belt is fixedly installed on the inner side wall of the frame, a supporting cross frame is fixedly connected to the top of the frame, a paving assembly is arranged at the bottom of the supporting cross frame, the paving assembly comprises a guide rail, a sliding seat and a scraper frame, the side wall of the supporting cross frame is fixedly connected to the guide rail, the sliding seat is slidably connected in the guide rail, and the scraper frame is fixedly connected to the side wall of the sliding seat.

[0008] Furthermore, the side wall of the supporting cross frame is movably connected to the driving rail via a bearing, the top of the supporting cross frame is fixedly connected to a connecting frame, one side of the connecting frame is movably connected to a driving arm via a bearing, the driving arm and the side wall of the sliding seat are both movably connected to a slider via a bearing, and the slider is slidably connected in the driving rail.

[0009] Furthermore, the inner side wall of the frame is fixedly connected with a support plate, the top of the support plate is movably connected with a swing plate through a bearing, and the top of the swing plate is fixedly connected with a material guide frame.

[0010] Furthermore, one end of the swing plate is movably connected to a roller via a bearing, and the inner side wall of the frame is fixedly connected to a partition.

[0011] Furthermore, a cam is movably connected to the bottom of the partition through a bearing, and the cam cooperates with the roller.

[0012] Furthermore, a compression spring is fixedly connected between the two swing plates, and a motor is fixedly connected to the top of the partition and the side wall of the connecting frame.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] When the utility model is in use, the cam, the roller and the compression spring cooperate with each other, thereby driving the two discharging frames to perform reverse reciprocating deflection. The reciprocating deflection of the discharging frames disperses and conveys the waste plastics in the unloading process, so that the crushed waste plastics are distributed all over the conveyor belt to avoid accumulation. At the same time, the reciprocatingly sliding scraper frame is used to assist in dispersing and spreading the waste household appliance plastics that are not dispersed in time and accumulate, thereby effectively avoiding the problem of plastic accumulation. By changing the accumulated and conveyed household appliance plastics into uniformly spread conveyance, the screening efficiency and screening effect of the subsequent screening mechanism for the household appliance plastics are effectively improved.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1: Figure 3 - Figure 5 As shown, a crushing and conveying device for processing waste plastics from household appliances includes a frame 1, a cover shell 2 is fixedly connected to the top of the frame 1, a crushing roller is arranged inside the cover shell 2, and the crushing roller is used to crush the waste plastics from household appliances, a discharging frame 3 is arranged at the bottom of the cover shell 2, and the discharging frame 3 is connected to the bottom of the cover shell 2, and the crushed waste plastic sheets flow to the top of the conveyor belt 4 through the discharging frame 3, and the inner side wall of the frame 1 is fixedly installed with a conveyor belt 4, and the conveyor belt 4 conveys the crushed waste plastics to a screening mechanism, and a supporting cross frame 5 is fixedly connected to the top of the frame 1, and a paving component 6 is arranged at the bottom of the supporting cross frame 5.

[0024] A support plate 8 is fixedly connected to the inner wall of the frame 1, and a swing plate 9 is movably connected to the top of the support plate 8 through a bearing, a material guide frame 10 is fixedly connected to the top of the swing plate 9, and a roller 11 is movably connected to one end of the swing plate 9 through a bearing, a partition plate 12 is fixedly connected to the inner wall of the frame 1, and a cam 13 is movably connected to the bottom of the partition plate 12 through a bearing, the cam 13 cooperates with the roller 11, a compression spring 14 is fixedly connected between the two swing plates 9, and a motor is fixedly connected to the top of the partition plate 12 and the side wall of the connecting frame 7, and the function of the motor is to drive the cam 13 and the driving arm 605 to rotate.

[0025] In the specific setting, the crushed home appliance plastic falls to the top of the conveyor belt 4 through the discharge frame 3. In the process of falling to the top of the conveyor belt 4, the motor drives the cam 13 to rotate. In the process of rotation, the cam 13 cooperates with the roller 11 and the compression spring 14 to drive the two swing plates 9 to reciprocate. The swing plates 9 drive the guide frame 10 to reciprocate synchronously during the reciprocating rotation. Since the bottom of the inner wall of the guide frame 10 is inclined downward, when the crushed home appliance plastic falls to the guide frame 10 through the discharge frame 3, as shown in FIG. Figure 5 As shown, the guide frame 10 evenly disperses the crushed plastics on the top of the conveyor belt 4 under the action of reciprocating deflection, so as to avoid the accumulation of crushed plastics of household appliances, which would affect the subsequent screening efficiency and effect;

[0026] Embodiment 2: Figure 1 - Figure 3 As shown, when the amount of household appliance plastic material discharged increases sharply, the discharge frame 3 and the guide frame 10 cannot fully disperse the household appliance plastic, which leads to the accumulation of household appliance plastic on the top of the conveyor belt 4. To solve this problem, the specific improvements are as follows:

[0027] The paving assembly 6 includes a guide rail 601, a sliding seat 602 and a scraper frame 603. The side wall of the supporting cross frame 5 is fixedly connected to the guide rail 601, and the sliding seat 602 is slidably connected in the guide rail 601. The scraper frame 603 is fixedly connected to the side wall of the sliding seat 602. The side wall of the supporting cross frame 5 is movably connected to the driving rail 604 through a bearing. The top of the supporting cross frame 5 is fixedly connected to the connecting frame 7, and one side of the connecting frame 7 is movably connected to the driving arm 605 through a bearing. The driving arm 605 and the side wall of the sliding seat 602 are both movably connected to the slider 606 through a bearing, and the slider 606 is slidably connected in the driving rail 604.

[0028] During the specific setting, the motor drives the driving arm 605 to rotate in a circle, and the driving arm 605 drives the driving rail 604 to reciprocate through the corresponding connected slider 606. During the reciprocating deflection, the driving rail 604 drives the slider 606 close to the bottom end, thereby driving the sliding seat 602 to slide back and forth in the guide rail 601. During the reciprocating sliding, the sliding seat 602 drives the scraper frame 603 to reciprocate. The reciprocatingly sliding scraper frame 603 transports and spreads the household appliance plastics accumulated on the top of the conveyor belt 4 to avoid the household appliance plastics being concentrated in one place and affecting the subsequent screening of the household appliance plastics.
