It is widely used in foaming shoe materials, photovoltaic films, wires and cables, hot melt adhesives, coatings, agricultural films and other fields.

[0003] During the production and processing of existing cross-linked polyethylene EVA, in order to facilitate storage and transportation, improve processing efficiency and save resources, granulation equipment is used to process the cross-linked polyethylene EVA into uniform particles for easy storage, transportation and subsequent processing. When the existing granulation equipment outputs the processed particles, the processed particles are usually output directly to the bottom surface or a single collecting device is used to collect the processed granular materials. The method of directly outputting the granular materials to the bottom surface makes the granular material collection process more troublesome. The collection method of a single collecting device requires shutdown to process the material particles inside the collecting device, which consumes manpower and time as a whole and affects the processing efficiency.

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0024] Please refer to Figures 1-7 A cross-linked polyethylene EVA production granulation device comprises a fixed bottom plate 100, a support leg 200, a collecting mechanism 300, a support frame 400 and a granulation mechanism 500 arranged just above the left side of the fixed bottom plate 100.

[0025] The collecting mechanism 300 includes a first mounting groove 310, a rotating disk 320, a placement groove 330, a collecting bucket 340, a baffle 350, a second mounting groove 360, a driving gear 370, and a driving motor 380. The first mounting groove 310 is provided on the upper surface of the right side of the fixed bottom plate 100. The rotating disk 320 is movably clamped inside the first mounting groove 310. The side of the rotating disk 320 is provided with teeth. The placement groove 330 is provided on the upper surface of the rotating disk 320. The collecting bucket 340 is placed inside the placement groove 330. The placement groove 330 can limit the collecting bucket 340. The collecting bucket 340 is placed to shake and tip over. The baffle 350 is formed on the upper end of the collecting bucket 340. The baffles 350 on the five collecting buckets 340 are formed as a whole. The arc-shaped parts together constitute a feed channel to prevent the granular material from spilling when the collecting barrel 340 is used alternately. The second mounting groove 360 ​​of the baffle 350 is opened on the right side of the upper surface of the rotating disk 320 and is close to the first mounting groove 310. The first mounting groove 310 and the second mounting groove 360 ​​intersect. The driving gear 370 is arranged inside the second mounting groove 360. The driving gear 370 can mesh with the teeth on the side of the rotating disk 320. The driving motor 380 is fixedly installed on the lower surface of the fixed base plate 100. The output shaft of the driving motor 380 passes through the fixed base plate 100 upward and the output shaft of the driving motor 380 extends into the second mounting groove 360. The driving gear 370 is fixedly installed on the upper end of the output shaft of the driving motor 380.

[0026] When it is necessary to switch the collection bucket 340 for use, start the drive motor 380. The drive motor 380 rotates and drives the driving gear 370 to rotate through the output shaft. The driving gear 370 rotates and meshes with the side teeth of the rotating disc 320, causing the rotating disc 320 to rotate. When the rotating disc 320 rotates, different collection buckets 340 can be moved below the discharge port 530 to complete the alternate use of the collection bucket 340. During this process, when one collection bucket 340 is in use, the other used collection bucket 340 can be removed without stopping the machine and the collection can be directly completed.

[0027] Please refer to Figure 1 、 Figure 2 、 Figure 3 On the upper surface of the left side of the fixed base plate 100, a support frame 400 is installed by bolts.

[0028] Above the support frame 400, a granulation mechanism 500 is installed. The granulation mechanism here is a well-known structural body at present and does not need to be described in detail. The granulation mechanism 500 includes a feed inlet 510, a granulation chamber 520, and a discharge port 530. The granulation chamber 520 is arranged above the right side of the support frame 400. The feed inlet 510 is arranged at the upper position on the right side of the granulation chamber 520, and the discharge port 530 is arranged at the lower position on the right side of the granulation chamber 520.

[0029] On the left side of the granulation chamber 520, a granulation drive assembly is installed by bolts. Inside the granulation chamber 520, a forming system and a pelletizing system are arranged. The motor acts as the driving power to drive the forming system inside the granulation chamber 520 to extrude the material into a shape, and then the pelletizing system is used for cutting. The above is a well-known structure at present. Legs 200 are formed on the lower surface of the fixed base plate 100.

[0030] During granulation, start the granulation drive assembly to make the granulation mechanism operate. Pour an appropriate amount of raw materials into the feed inlet 510. After being processed by the components inside the granulation chamber 520, the raw materials are discharged downward through the discharge port 530.

[0031] In some examples, anti-slip pads can be installed on the bottom surface of the legs 200 to prevent the overall device from moving during operation.

[0032] The above are only the preferred embodiments of the present invention and do not limit the present invention. Any modification of the technical solutions recorded in the foregoing embodiments, any equivalent replacement of some technical features, and any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
