Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] Please see Figures 1 to 6This utility model provides a technical solution: a waste cleaning device for plastic boxes and plastic molds of optical fibers and cables, including a cleaning box 1 and a crushing roller 4. The top of the cleaning box 1 is provided with a feeding trough 2 for injection molding waste to enter. A first guide plate 3 is symmetrically arranged on the upper side inside the cleaning box 1. Two crushing rollers 4 for crushing injection molding waste are provided in the middle of the cleaning box 1. A screen 5 for screening debris is provided below the two crushing rollers 4. The screen 5 is fixed inside the mounting frame 6 and is set in an inclined shape inside the mounting frame 6. The outside of the mounting frame 6 is connected to the contact surface of the cleaning box 1 and the transparent cover plate 8 through a telescopic cover 7. The transparent cover plate 8 is installed at the front end of the cleaning box 1 through a fixing bolt 9.

[0033] The bottom of the mounting frame 6 is fixed with a box for mounting the vibration motor 10. Connecting brackets 11 are provided on both sides of the bottom of the mounting frame 6. The lower end of the connecting bracket 11 is fixed to the extension seat 13 by the first spring 12. The extension seat 13 is fixed inside the cleaning box 1.

[0034] A recovery pipe 14 is provided above one side of the mounting frame 6. The side end of the recovery pipe 14 passes through the side of the cleaning box 1 and is connected to the negative pressure end of the particle feeding pump 15. The other end of the particle feeding pump 15 passes through the conveying pipe 16 to the upper part of the interior of the cleaning box 1 and is located above the first guide plate 3. A second guide plate 17 is provided on one side of the conveying pipe 16. The second guide plate 17 is fixed to the top of the interior of the cleaning box 1. A discharge pipe 18 is connected to the bottom flange of the cleaning box 1. A receiving frame 19 is provided below the discharge pipe 18. Considering the existing equipment, a filtration structure using a screen for screening is designed at the discharge end. However, it does not have a discharge end for the crushed material that has not passed through the screening structure. That is, when the crushing effect is not good and there are a lot of large particles and debris, it will block the filter structure, making it impossible to filter. It will also block the mesh and cause the material to accumulate on the filter screen 36, thus making the device unable to work properly. This utility model uses the cooperation of the recovery pipe 14, the particle feeding pump 15, the conveying pipe 16 and the second guide pipe to transport the waste particles accumulated on one side of the filter screen 36 to the two crushing rollers 4 for washing and crushing. Thus, the waste particles that have not passed through the filter screen 36 can be crushed again by the crushing rollers 4.

[0035] The bottom of the cleaning box 1 is fixed to the movable base 20 by support legs. Self-locking casters 21 are installed at the four corners of the bottom of the movable base 20. A weighing sensor 22 for weighing the waste particles is installed in the middle of the movable base 20. The weighing sensor 22 is connected to the control panel 23 at the front of the movable base 20 by wires. The control panel 23 is also connected to the audible and visual alarm 24 at the front of one of the support legs by wires. Considering that the particles that have been crushed by the crushing roller 4 and can be screened by the filter screen 36 will enter the receiving frame 19, in order to facilitate the workers to empty the full receiving frame 19 in time, the audible and visual alarm 24, the control panel 23 and the weighing sensor 22 will work together to remind the waste particles entering the receiving frame 19. That is, a threshold for the waste particles to be full is set. When the particle weight reaches the threshold, the audible and visual alarm 24 will be activated to remind the on-site equipment care personnel to empty the material.

[0036] The weighing sensor 22 has support blocks 25 on both sides to protect the detection end of the weighing sensor 22. The support blocks 25 are movably connected to the upper end of the sleeve block 26, and the sleeve block 26 is fixed to the upper end of the movable seat 20. Each sleeve block 26 has a second spring 27 inside to abut against the support block 25. A cavity for the guide rod 28 to pass through is opened at the upper end of the sleeve block 26. The guide rod 28 is fixed to the lower end of the support block 25. A polyurethane protective block 29 is fixed to the bottom of the guide rod 28. The second spring 27, support blocks 25 and sleeve blocks 26 play a protective role for the detection end of the weighing sensor 22. That is, when the worker places the receiving frame 19 to the detection end of the weighing sensor 22, the support blocks 25 will be used for protection to avoid the receiving frame 19 directly contacting the detection end and causing a wound.

[0037] Among them, C-shaped parts 30 are symmetrically fixed at the upper end of the movable seat 20, and a C-shaped mesh silencing plate 31 is fixed on the inner side of each C-shaped part 30. The C-shaped mesh silencing plate 31 in the middle of the C-shaped part 30 reduces the noise coming out of the discharge pipe 18.

[0038] The top of the cleaning box 1 is fixed to the roof 33 by the connecting rod 32. A sound-absorbing sponge 34 is fixed at the lower end of the roof 33. The sound-absorbing sponge 34 reduces the noise coming out of the feed chute 2.

[0039] The upper side of the cleaning box 1 is provided with a negative pressure U-shaped cover 35. A filter screen 36 is installed on the surface of the negative pressure U-shaped cover 35. A negative pressure chamber is provided inside the negative pressure U-shaped cover 35. The side of the negative pressure chamber passes through the interior of the dust collection box 41 through the negative pressure pipe 37 and is connected to the bag opening of the dust collector bag 38. By setting up the U-shaped cover, the negative pressure pump 39 and the dust collector bag 38 to cooperate with each other, the dust attached to the injection molding waste is collected. That is, the dust raised by the crushing roller 4 will be sucked into the interior of the dust collector bag 38 by the negative pressure generated by the negative pressure pump 39. The presence of the filter screen 36 prevents the debris from entering the interior of the dust collector bag. That is, the mesh size of the filter screen 36 used later is smaller than that of the injection molding waste debris.

[0040] The dust collection box 41 has a partition fixed to the lower middle part. A negative pressure pump 39 is fixed to the lower end of the partition through a steel bracket. The discharge end of the negative pressure pump 39 passes through the conduit 40 to the outside of the dust collection box 41. The negative pressure end of the negative pressure pump 39 passes through the pipe to the top of the partition and is located below the dust collector bag 38. Connecting rings 43 for installing tension springs 42 are provided at the four corners of the dust collector bag 38. The tension springs 42 are fixed inside the dust collection box 41. Shaping rings 44 for pulling the dust collector bag 38 are fixed at equal intervals on the outside of the dust collector bag 38. The connecting rings 43 and tension springs 42 are used to pull the dust collector bag 38 open. The shaping rings 44 prevent the dust collector bag 38 from deforming due to negative pressure.

[0041] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
