Description

Technical Field

[0001] The utility model relates to the technical field of granulation devices, in particular to a granulation device for plastic particles. Background Art

[0002] When processing plastic powder into plastic granules, a dry granulator is used. That is, the dry granulator drives the plastic powder to move through a screw feeder, then presses it into sheets through a tabletting roller, and then breaks the material into granules through a crushing device, and finally discharges it through a discharge hopper.

[0003] At present, a collection device is set under the discharge hopper to recycle the plastic particles in time. However, when the carrying capacity of the collection device reaches saturation, the plastic particles will fall into the external environment.

[0004] The main reason for the above problems is that when the carrying capacity of the collecting device reaches saturation, the collecting device needs to be removed. At this time, any device for collecting plastic particles is placed under the discharge hopper, and the outlet opened on the bottom end face of the discharge hopper is in a directly exposed state. When the plastic particles produced by the processing are still being discharged, the plastic particles will directly fall into the external environment, resulting in the loss of some plastic particles. To address the above problems, we propose a granulation device for plastic particles. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0026] The embodiment of the present application provides a granulation device to solve the problem that plastic particles fall into the external environment when the carrying capacity of the collecting device reaches saturation, thereby achieving automatic blocking below the discharge hopper.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] The utility model embodiment discloses a granulating device for plastic particles.

[0029] According to the attached Figure 1-5 As shown, the dry granulator comprises a main body 1 of the dry granulator, and a primary processing unit, a tablet pressing unit, a granulating unit and a discharging unit arranged on the main body 1 of the dry granulator.

[0030] The primary processing unit comprises a processing bucket 2 fixedly arranged on the top end surface of the dry granulator body 1 , a screw conveyor 202 arranged inside the processing bucket 2 , and an upper hopper 201 fixedly arranged on the top end surface of the processing bucket 2 .

[0031] The tableting unit comprises a receiving bucket 3 fixedly arranged on one side of the dry granulator body 1 and two sets of tableting rollers 301 rotatably arranged inside the receiving bucket 3 . The top end surface of the receiving bucket 3 is connected to the bottom end surface of the processing bucket 2 .

[0032] The granulation unit comprises a connecting bucket 4 arranged on the bottom end surface of the receiving bucket 3 and a granulation knife 401 rotatably arranged inside the connecting bucket 4 . The bottom end surface of the connecting bucket 4 is fixedly connected to the top end surface of the discharging bucket 5 .

[0033] The discharging unit includes a discharging hopper 5 disposed on one side of the dry granulator body 1 and a collecting box 501 placed below the discharging hopper 5 .

[0034] The dry granulator body 1, the primary processing unit, the tableting unit, the granulation unit and the discharge unit constitute a dry granulator of model TFC-220. When in use, the plastic powder is added to the interior of the processing bucket 2 through the upper hopper 201, and then the plastic raw material is extruded through the screw conveyor 202 arranged inside the processing bucket 2. The extruded plastic enters the interior of the receiving bucket 3, and is processed into sheets by two sets of tableting rollers 301 arranged inside the receiving bucket 3. Then the sheet-shaped plastic enters the interior of the connecting bucket 4, and the granulating knife 401 arranged inside the connecting bucket 4 breaks it into plastic particles. Finally, the plastic particles are collected in the collection box 501 through the discharge hopper 5.

[0035] A blocking mechanism 6 is provided on the bottom end surface of the discharge hopper 5. Through the blocking mechanism 6, the outlet of the discharge hopper 5 can be automatically opened and closed. The blocking mechanism 6 includes a guide rod 601, which is fixedly arranged on one side of the dry granulator body 1. A baffle 602 is slidably arranged on the outer walls of the two groups of guide rods 601. The baffle 602 is used to block the outlet of the discharge hopper 5. The outer wall of the guide rod 601 is provided with a spring 604 for elastically returning the baffle 602. One end of the spring 604 is fixedly connected to the outer wall of the baffle 602. A positioning block 605 is fixedly connected to one end of the guide rod 601 away from the spring 604. The positioning block 605 is used to limit the moving position of the baffle 602 relative to the guide rod 601. When one side of the baffle 602 abuts against the outer wall of the positioning block 605, the baffle 602 blocks the outlet of the discharge hopper 5.

[0036] The linkage plate 603 is fixedly connected to the bottom end face of the baffle 602, and the linkage between the collecting box 501 and the discharge hopper 5 is realized through the linkage plate 603. One side of the collecting box 501 is against the outer wall of the linkage plate 603, that is, when the collecting box 501 is placed under the discharge hopper 5, the collecting box 501 can drive the baffle 602 to move away from the discharge hopper 5 through the linkage plate 603, so that the outlet opened on the bottom end face of the discharge hopper 5 is in an open state, so that the plastic particles can directly enter the interior of the collecting box 501. The bottom end face of the collecting box 501 is provided with a self-locking roller. Through the provided self-locking roller, the placement position of the collecting box 501 relative to the dry granulator body 1 can be fixed, so that the baffle 602 controlled by the collecting box 501 will not move at will.

[0037] The granulation device for plastic particles is provided with a blocking mechanism 6 below the discharge hopper 5. The switch state of the blocking mechanism 6 is controlled by the placement position of the collecting box 501, so that when the collecting box 501 collects plastic particles, the blocking mechanism 6 can be automatically opened. When the collecting box 501 is taken away, the blocking mechanism 6 is automatically closed, so that the residual plastic particles in the discharge hopper 5 will not be directly scattered into the external environment, thereby avoiding the waste of plastic particles.
