Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1
[0028] A preferred embodiment of the plastic raw material feeding device provided by this utility model is, for example... Figures 1 to 5 As shown: A plastic raw material feeding device includes a housing 1; a feeding sleeve 2 fixedly penetrating the top of the housing 1; a displacement component 3 assembled inside the housing 1, which can adjust the particle size of the plastic crushed material; the displacement component 3 includes a limiting roller 301 disposed on the upper middle side inside the housing 1, the front and rear ends of the limiting roller 301 slidingly penetrating the housing 1; and an electric push rod 302 fixedly connected to the front and rear ends outside the housing 1, the electric push rod 302 having a self-locking function, and the output end of the electric push rod 302 being fixedly connected to the outer wall of the limiting roller 301, the axis of the limiting roller 301 coinciding with the center of each pair of crushing rollers 401, the left worm wheel 402 and the worm 404 being designed with a left-hand threaded connection, and the right worm wheel 402 and the worm 404 being designed with a right-hand threaded connection.
[0029] It should be noted that existing plastic raw material feeding devices still have certain shortcomings in actual use. They cannot adjust the particle size of the crushed plastic to the range required by the operator, thus reducing the crushing effect of the plastic.
[0030] In this embodiment, the operator first turns on the electric push rod 302, which drives the limiting roller 301 to move along the direction or opposite direction of the crushing roller 401, thereby adjusting the distance between the limiting roller 301 and the crushing roller 401, that is, adjusting the particle size of the plastic to be crushed. After the adjustment is completed, the operator pours the plastic from the feeding sleeve 2 into the position between the crushing roller 401 and the limiting roller 301.
[0031] In a further preferred embodiment of this utility model, a crushing assembly 4 is assembled inside the housing 1. The crushing assembly 4 can work with the limiting roller 301 to crush plastic. The crushing assembly 4 includes crushing rollers 401 rotatably disposed on the left and right sides of the middle of the housing 1, with the front end of the crushing rollers 401 penetrating through the housing 1; a worm gear 402 fixedly connected to the front end of the crushing rollers 401; a first motor 403 fixedly connected to the left side of the front end of the housing 1; and a worm 404 fixedly disposed to the right side of the first motor 403, with the right end of the worm 404 rotatably connected to the housing 1, and the worm 404 meshing with the teeth of the worm gear 402.
[0032] In this embodiment, after the plastic is poured into the upper part of the housing 1 through the feeding sleeve 2, the operator turns on the first motor 403. The first motor 403 drives the worm gear 402 to rotate the crushing roller 401. That is, the crushing roller 401 on the left rotates clockwise and the crushing roller 401 on the right rotates counterclockwise, so that the limiting roller 301 cooperates with the rotating crushing roller 401 to crush the plastic.
[0033] Example 2
[0034] Based on Example 1, a preferred embodiment of the plastic raw material feeding device provided by this utility model is as follows: Figures 1 to 5 As shown: The front and rear ends of the housing 1 are integrally provided with guide holes 5. The guide holes 5 are through holes and are sleeved on the outside of the limiting roller 301. The indicator component provided on the outside of the limiting roller 301 can control the distance of the limiting roller 301 after displacement within the range required by the operator. The indicator component includes a sealing plate 6 fixedly sleeved on the front and rear ends of the limiting roller 301, the sealing plate 6 and the housing 1 are in contact with each other; an indicator rod 7 fixed on the outer wall of the sealing plate 6 at the rear end; and a scale 8 integrally provided on the rear ends of the housing 1.
[0035] In this embodiment, when the distance between the limiting roller 301 and the crushing roller 401 is adjusted, the limiting roller 301 drives the sealing plate 6 to seal the outside of the guide hole 5, preventing the crushed plastic from being discharged to the outside through the guide hole 5. The electric push rod 302 is then turned off after the sealing plate 6 drives the indicator rod 7 to point to the value of the scale 8, which meets the needs of the staff. At this time, the particle size of the crushed plastic is precisely controlled.
[0036] In a further preferred embodiment of this utility model, a bracket 9 is fixedly provided at the lower end of the interior of the housing 1, and a clearance hole 10 is integrally provided at the lower right end of the interior of the housing 1. The clearance hole 10 is a through hole. A conveying assembly provided inside the bracket 9 can transfer the crushed plastic to the next process. The conveying assembly includes a rotating shaft 11 that is rotated to the left and right sides inside the bracket 9; a second motor 12 fixedly provided at the right rear end of the bracket 9, the output end of the second motor 12 passing through the bracket 9, and the output end of the second motor 12 being fixedly connected to the rotating shaft 11 on the right side; pulleys 13 fixedly sleeved at the front and rear ends of the rotating shaft 11; and a belt tightly fitted around the pulleys 13. A toothed belt 14 meshes with the teeth of a pulley 13. Several push plates 15 are fixed to the outside of the toothed belt 14. The distance between any two push plates 15 is greater than the distance between any two crushing rollers 401. Baffles 16 are fixed to the front and rear ends of the top of the support 9. A support plate 17 is fixed to the upper inside of the support 9. The support plate 17 is parallel to the baffles 16 and perpendicular to the push plates 15. The top surface of the baffles 16 and the top surface of the push plates 15 are designed to be on the same plane. A controller 18 is fixed to the outer wall of the housing 1. The controller 18 is connected to the first motor 403, the second motor 12 and the electric push rod 302 through wires.
[0037] In this embodiment, when the plastic is crushed, the operator can turn on the second motor 12. The second motor 12 drives the rotating shaft 11 to drive the pulley 13 to rotate clockwise in conjunction with the toothed belt 14, so that the crushed plastic falls into the top of the toothed belt 14. At this time, the toothed belt 14 drives the push plate 15 to push the plastic through the clearance hole 10 to move to the next process. The baffle 16 can prevent the plastic from falling off the toothed belt 14 during the transfer. The support plate 17 supports the wall thickness at the upper end of the toothed belt 14 to prevent the wall thickness at the upper end of the toothed belt 14 from being dented.
[0038] In summary, this application can control the particle size of crushed plastic within the range required by the operator, thereby improving the crushing effect of plastic. Through the design of the conveying function, the crushed plastic can be transferred to the next process.
