[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] like Figure 1-Figure 4 As shown, a strip plastic crusher comprises a shell 1, a control panel 2 is fixedly mounted on the outer side wall of the shell 1, a crushing roller 3 is arranged at the upper end of the shell 1, a screen 13 is arranged inside the shell 1, a first discharge port 4 is arranged on one side of the screen 13 on the shell 1, a vibration mechanism is arranged at the lower end of the screen 13, a press box 5 is connected to one side of the first discharge port 4 through a guide plate 23, a first hydraulic cylinder 6 is fixedly mounted on the upper end of the press box 5 through a first bracket 18, an input end of the first hydraulic cylinder 6 is electrically connected to an output end of the control panel 2, the first hydraulic cylinder 6 is controlled to work through the control panel 2, a press plate 7 is fixedly connected to the lower end of the first hydraulic cylinder 6, a baffle 9 is movably connected to the other side of the press box 5,
[0023] There are two groups of crushing rollers 3, which are symmetrically arranged on the left and right. Crushing teeth are arranged on the crushing rollers 3. The two groups of crushing rollers 3 are rotatably installed in the shell 1. A first motor 10 is installed on each crushing roller 3, and the first motor 10 is fixedly installed on the outer wall of the shell 1. The upper end of the crushing roller 3 is connected to a feed hopper 11 on the shell 1. The feed is fed through the feed hopper 11, and the plastic is crushed by the crushing teeth on the two groups of symmetrical crushing rollers 3.
[0024] The screen 13 and the guide plate 23 are both arranged at an angle, and a connecting plate 12 is fixedly connected to the outer side of the screen 13, and the connecting plate 12 is fixedly connected to the outer side wall of the shell 1. The first discharge port 4 is arranged on the side of the screen 13 with a lower horizontal height, and the crushed plastic is screened during the movement of the inclined screen 13.
[0025] The crushing roller 3 and the feed hopper 11 are connected to one side of the upper end of the shell 1. The crushing roller 3 and the feed hopper 11 are located on the upper side of the higher end of the screen 13. The crushed material first contacts the higher end of the inclined screen 13, and then moves downward along the screen 13, so that the screen 13 has enough time to screen the plastic.
[0026] The vibration mechanism includes a rotating shaft 14, which is horizontally arranged at the lower end of the screen 13. There are multiple rotating shafts 14, and each rotating shaft 14 is fixedly connected to a cam 16. When the rotating shaft 14 rotates, it drives the cam 16 to rotate. The protruding part of the cam 16 contacts and hits the screen 13, and the surface of the screen 13 vibrates, thereby accelerating the screening speed of the screen 13 for the crushed plastic, and accelerating the crushed plastic to be discharged from the first discharge port 4 or pass through the screen 13.
[0027] A second motor 17 is fixedly connected to the rotating shaft 14. The second motor 17 is fixedly installed on the outer wall of the shell 1. The input end of the second motor 17 is electrically connected to the output end of the control panel 2. The control panel 2 controls the operation of the second motor 17. The second motor 17 provides power for the rotation of the rotating shaft 14. A total of multiple rotating shafts 14 are provided, so that most areas of the lower end of the screen 13 can vibrate.
[0028] A molding box 15 is arranged inside the pressing box 5, and the upper end of the molding box 15 is opened. The dimensions of the inside of the molding box 15 and the outside of the pressing plate 7 match each other. The function of the screen 13 is to screen out large-volume crushed materials. If the large-volume crushed materials are not compressed, they will occupy a large amount of space. In order to facilitate transportation, the pressing plate 7 is driven by the first hydraulic cylinder 6 to move to compress the large-volume crushed materials. After compression, the plastic can store more plastic in a smaller space.
[0029] The baffle door 9 is connected to the material pressing box 5 by a latch, and a push plate 8 is provided on the opposite side of the baffle door 9. A second hydraulic cylinder 19 is fixedly connected to the push plate 8. The second hydraulic cylinder 19 is fixed to the side of the material pressing box 5 through a second bracket 20. The input end of the second hydraulic cylinder 19 is electrically connected to the output end of the control panel 2. After the material pressing is completed, in order to facilitate the molding box 15, the push plate 8 is driven to move by the second hydraulic cylinder 19, and the latch on the baffle door 9 is pulled out at the same time, and the molding box 15 is automatically pushed out by thrust, saving manpower.
[0030] The lower end of the shell 1 is fixedly connected to a supporting leg 21, and there are four supporting legs 21 in total. The four supporting legs 21 are evenly arranged at the four corners of the lower end of the shell 1. The middle part of the lower end of the shell 1 is connected to a second discharge port 22, and small-particle plastics are discharged through the second discharge port 22. Since the collision volume between small-particle plastic fragments is small, even without compression, they will only occupy a small space.
[0031] The working principle of the utility model is as follows: the device adds the plastic to be crushed through the feed hopper 11. After the strip plastic enters the shell 1, the plastic is crushed by the crushing teeth on the two sets of symmetrical crushing rollers 3. The crushed plastic falls onto the screen 13. The screen 13 screens the crushed plastic. The large plastic fragments are introduced into the pressing box 5 through the first discharge port 4 and are pressed by the pressing plate 7 to reduce the occupied space. Since the screen 13 is inclined and a vibration mechanism is provided at the lower end of the screen 13, the cam 16 of the vibration mechanism rotates and periodically hits the screen 13, so that the screen 13 can screen the plastic faster. The device can quickly screen the crushed plastic, and after screening, the large plastic can be pressed into a smaller package through the pressing plate 7 in the pressing box 5, which is convenient for transportation and processing.
[0032] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
