[0026] 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.
[0027] The utility model provides a technical solution:
[0028] See also Figures 1 to 5 , a processing device for EVA elastic water-permeable plastic track particles, comprising a drying box 1 and a feeding pipe 2 connected to the upper side of the drying box 1, a screening component 3 is provided inside the drying box 1, and the screening component 3 comprises a double-axis motor 31 fixedly installed inside the drying box 1;
[0029] The output shafts at the front and rear ends of the dual-axis motor 31 are fixedly connected with cams 32, and the extension columns on the sides away from the two cams 32 are sleeved with connecting plates 33. A collecting chamber 34 is opened on the lower side of the interior of the drying box 1, and a screening frame 35 is slidably connected to the interior of the drying box 1. The other sides of the two connecting plates 33 are respectively sleeved on the outside of the extension columns fixedly connected on the front and rear sides of the screening frame 35. The screening frame 35 is directly above the collecting chamber 34. Four first return springs 36 are fixedly connected to the lower side of the screening frame 35, and the other ends of the four first return springs 36 are fixedly connected to the internal side wall of the drying box 1. A heating device 37 is fixedly installed on the upper side of the interior of the drying box 1, and a feeding assembly 38 is provided on the right side of the drying box 1 and the right side of the screening frame 35.
[0030] The screening frame 35 is arranged obliquely, and the length of the two first return springs 36 on the left side is greater than the length of the two first return springs 36 on the right side.
[0031] The material discharge assembly 38 includes four guide grooves 381 provided on the right side of the drying box 1 , the four guide grooves 381 are all slidably connected with guide plates 382 , and the right side of the four guide plates 382 is fixedly connected with the same baffle 383 .
[0032] Two rollers 384 are rollingly connected to the lower side of the baffle plate 383, and a closing plate 385 is fixedly installed on the right side of the screening frame 35 by bolts.
[0033] By adopting the above technical scheme, firstly, after the materials enter the interior of the drying box 1 through the feeding pipe 2, the materials will fall into the screening frame 35, and the dual-axis motor 31 is started to drive the two cams 32 to rotate. Every time the cam 32 rotates one circle, since one side of the connecting plate 33 is sleeved on the outer side of the extension column on the side of the cam 32, and the other side of the connecting plate 33 is sleeved on the outer side of the extension column on the side of the screening frame 35, after the cam 32 pulls the connecting plate 33, the connecting plate 33 will pull the screening frame 35, so that the screening frame 35 repeatedly moves downward. At the same time, the four first return springs 36 under the screening frame 35 push the screening frame 35 after being squeezed by the screening frame 35, so that the screening frame 35 moves upward quickly. In the process of the screening frame 35 repeatedly moving downward, the unqualified materials in the screening frame 35 will be screened out by the screening frame 35 and fall into the collecting chamber 34. The material remaining in the screening frame 35 will be dried by the heat generated by the heating device 37. When taking out the material, the baffle 383 can be pulled so that the four guide plates 382 on the left side of the baffle 383 will slide in the four guide grooves 381 on the right side of the drying box 1. At the same time, the rollers 384 under the baffle 383 will also support the baffle 383 while rolling. As the baffle 383 moves away from the working box, the unqualified material in the collecting chamber 34 can be taken out directly, and the material in the screening frame 35 will be taken out after the closing plate 385 fixed by bolts is disassembled. Since the material is dried in the drying box 1, the repeatedly shaking screening frame 35 will screen the material, so that the unqualified material is screened out, which effectively reduces the time consumed for subsequent processing of the material and avoids repeated transportation of the material, thereby improving the processing efficiency of the material.
[0034] Specifically, Figure 4 As shown, the interior of the feeding pipe 2 and the interior of the drying box 1 are both provided with a material shaking component 4, and the material shaking component 4 includes a feeding hopper 41 slidably connected to the interior of the feeding pipe 2, and the feeding hopper 41 is located above the screening frame 35.
[0035] Two chute grooves 42 are provided on both sides of the feeding pipe 2 , and two sliders 43 are fixedly connected to both sides of the feeding hopper 41 . The four sliders 43 are slidably connected in the four chute grooves 42 , respectively.
[0036] The lower sides of the four sliding blocks 43 are fixedly connected with second return springs 44 , and the bottom ends of the four second return springs 44 are fixedly connected to the inner lower sides of the four sliding grooves 42 .
[0037] Two support plates 45 are fixedly connected to the upper side of the screening frame 35. The support plates 45 are in an inverted "L" shape. The two support plates 45 pass through the upper side of the working box and are slidably connected to the front and rear sides of the feeding pipe 2. After the upper sides of the two support plates 45 move upward, they are overlapped on the lower side of the feeding hopper 41.
[0038] By adopting the above technical scheme, first, after the material is poured into the feeding pipe 2, it will fall into the upper hopper 41. During the up and down movement of the screening frame 35, the upward movement of the screening frame 35 will simultaneously drive the two support plates 45 on its upper side to move upward, so that the support plates 45 push the upper hopper 41. As the upper hopper 41 repeatedly moves inside the upper hopper 41, the sliders 43 on both sides thereof will slide in the slide grooves 42 inside the feeding pipe 2. When the support plates 45 move downward, the second return springs 44 inside the slide grooves 42 will pull the sliders 43 downward, so that the upper hopper 41 is quickly reset. After the upper hopper 41 moves up and down, the material inside the upper hopper 41 will also gradually enter the screening frame 35. Since the screening frame 35 moves up and down to screen the material, the upper hopper 41 will also move up and down repeatedly to prevent the material from being blocked inside the upper hopper 41, which ensures the feeding speed of the upper hopper 41 and avoids affecting the processing efficiency of the material.
[0039] Working principle: First, the material enters the drying box 1 through the feeding pipe 2 and falls into the screening frame 35, and the dual-axis motor 31 drives the two cams 32 to rotate. Every time the cam 32 rotates one circle, the connecting plate 33 pulls the screening frame 35, so that the screening frame 35 moves downward repeatedly, and the four first return springs 36 under the screening frame 35 push the screening frame 35. At this time, unqualified materials in the screening frame 35 will be screened out by the screening frame 35 and fall into the collecting chamber 34. The material remaining in the screening frame 35 will be dried by the heat generated by the heating device 37. When taking out the material, the baffle 383 can be pulled so that the four guide plates 382 on the left side of the baffle 383 will slide in the four guide grooves 381 on the right side of the drying box 1. At the same time, the roller 384 under the baffle 383 starts to roll. The unqualified material in the collecting chamber 34 can be taken out directly, and the material in the screening frame 35 will be taken out after the closing plate 385 fixed by bolts is disassembled.
[0040] After the material is poured into the feeding pipe 2, it will fall into the upper hopper 41, and the two support plates 45 on the upper side of the screening frame 35 will move upward with the screening frame 35 and push the upper hopper 41. At this time, the sliders 43 on both sides of the upper hopper 41 will slide in the slide groove 42 inside the feeding pipe 2, and when the support plate 45 moves downward, the second return spring 44 inside the slide groove 42 will pull the slider 43 downward, so that the upper hopper 41 is quickly reset. After the upper hopper 41 moves up and down, the material inside the upper hopper 41 will gradually enter the screening frame 35.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
