AI Technical Summary

Technical Problem

In the production of desktop pure electric servo horizontal injection molding machines, plastic particles are prone to sticking together or bridging in the funnel due to factors such as environmental humidity and electrostatic adsorption, forming lumpy materials with uneven density. This leads to differences in melting rate, resulting in semi-molten nuclei and agglomerated voids, which affects product quality.

Method used

The design includes a screening component and a cleaning component. The screening component uses a servo motor to drive the screen plate for screening, while the cleaning component uses scrapers and top columns to clean large particles of raw materials, preventing clumping and uneven size, and ensuring the uniformity of the raw materials.

Benefits of technology

It effectively reduces the clumping and uneven size of injection molding raw materials, prevents internal defects in the melt, improves product surface quality, and avoids defects such as silver streaks, flow marks, and shrinkage cavities.

[0025] Example one

[0026] As Figures 1-6As shown, a desktop pure electric servo type horizontal injection molding machine, including desktop pure electric servo type horizontal injection molding machine body 1, the top of one side of desktop pure electric servo type horizontal injection molding machine body 1 is installed with the blanking pipe 11, one end of blanking pipe 11 is connected with the blanking funnel 12, both sides of blanking funnel 12 are fixedly connected with the inclined support plate 13, the other end of inclined support plate 13 is fixedly connected to the top of one side of desktop pure electric servo type horizontal injection molding machine body 1, the top of desktop pure electric servo type horizontal injection molding machine body 1 is provided with screening assembly, the middle of blanking funnel 12 is provided with cleaning assembly.

[0027] Screening assembly includes the supporting plate 2, the servo motor 21, two groups of rectangular sliding groove 22, the sieve plate 23, the support rod 24 and the limiting hollow sleeve 25, the supporting plate 2 is fixedly connected to the top of one side of desktop pure electric servo type horizontal injection molding machine body 1, the servo motor 21 is installed on the top of supporting plate 2, two rectangular sliding grooves 22 are respectively opened in the middle of both sides of blanking funnel 12, both sides of sieve plate 23 are respectively slidably connected to the middle of two groups of rectangular sliding grooves 22, the bottom end of support rod 24 is fixedly connected to the top of one side of desktop pure electric servo type horizontal injection molding machine body 1 close to supporting plate 2, the top end of limiting hollow sleeve 25 is fixedly connected to support rod 24.

[0028] Screening assembly further includes slide column 3, rotating disc 31, rotating rod 32 and notched plate 33, the middle of slide column 3 is slidably connected to the middle of limiting hollow sleeve 25, one end of slide column 3 is fixedly connected to one side of sieve plate 23, rotating disc 31 is installed on the output end of servo motor 21, rotating rod 32 is fixedly connected to the middle of one side of rotating disc 31 away from servo motor 21, one side of notched plate 33 is fixedly connected to the end of slide column 3 away from sieve plate 23, the middle of rotating rod 32 is slidably connected to the middle of notched plate 33.

[0029] When working, the other end of blanking pipe 11 is connected to the melting pipe, when the plastic raw material needs to be injection molded, it can be poured into the inside of blanking funnel 12, at this time, sieve plate 23 can receive the poured raw material, then drive servo motor 21 to make servo motor 21 and rotating rod 32 rotate, rotating rod 32 will slide in the middle of notched plate 33 when rotating, at the same time, rotating rod 32 will also drive notched plate 33 to move when rotating, the movement of notched plate 33 will drive slide column 3 and sieve plate 23 to move synchronously, at this time, the movement of slide column 3 is limited by limiting hollow sleeve 25, so that slide column 3 drives sieve plate 23 to reciprocatingly and linearly slide in the middle of rectangular sliding groove 22, under the sliding of sieve plate 23, the plastic particles on the top of sieve plate 23 can be screened, so that the small particle raw material falls into the inside of blanking pipe 11, and finally flows into the melting pipe to melt and injection molding, at the same time, under the screening of sieve plate 23, the raw material on the top of sieve plate 23 can collide with each other, under the collision, the raw material which forms agglomeration phenomenon due to environmental humidity, electrostatic adsorption or mutual extrusion can be dispersed.

[0030] This step can reduce the caking and size of the injection material by the setting of the screening assembly, thereby preventing the caking or size of the material, which is easy to cause the difference in the melting rate of the material, resulting in the presence of semi-melted nuclei and agglomerated cavities in the melt, and further causing the surface of the injection product to produce silver lines, flow marks, shrinkage holes and other defects.

[0031] Example Two

[0032] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 , the cleaning assembly includes two groups of support blocks 4, a lead screw 41, a baffle 42 and a material collecting box 43. The two support blocks 4 are fixedly connected to the two sides of the discharging hopper 12, the lead screw 41 is rotatably connected to the middle part of the two groups of support blocks 4, the baffle 42 is hingedly connected to the middle part of the side of the discharging hopper 12, and the material collecting box 43 is installed on the side of the discharging hopper 12 close to the baffle 42.

[0033] The cleaning assembly further includes a threaded sleeve 5, a limiting sliding groove 51 and a sliding rod 52. The threaded sleeve 5 is threadedly connected to the middle part of the lead screw 41, the limiting sliding groove 51 is formed on the side of the discharging hopper 12 close to the lead screw 41, one end of the sliding rod 52 is fixedly connected to the side of the threaded sleeve 5 close to the discharging hopper 12, the middle part of the sliding rod 52 is slidingly connected to the middle part of the limiting sliding groove 51, and the upper and lower sides of the sliding rod 52 are in close contact with the upper and lower sides of the limiting sliding groove 51.

[0034] The cleaning assembly further includes two groups of connecting columns 6, a scraper 61 and two groups of jacks 62.

[0035] When too much large particle material accumulates on the screen plate 23, one end of the lead screw 41 can be held and rotated, so that the lead screw 41 rotates in the middle part of the support block 4. The threaded sleeve 5 and the sliding rod 52 can be driven to move synchronously under the rotation of the lead screw 41. At this time, the sliding rod 52 is limited by the limiting sliding groove 51 when moving, so as to be forced to change its movement track, so that the sliding rod 52 slides in the middle part of the limiting sliding groove 51. The connecting column 6, the scraper 61 and the jack 62 are driven to move synchronously in the sliding process of the sliding rod 52. The large particle injection material remaining on the screen plate 23 can be pushed under the sliding of the scraper 61.

[0036] When the scraper 61 drives the top post 62 to move to the baffle 42, the top post 62 can abut against the baffle 42 and push the baffle 42 to expand outward, so that the feeding hopper 12 forms a discharging opening, at this time, the lead screw 41 is continuously rotated, so that the scraper 61 pushes the large-particle raw materials to the discharging opening formed by the baffle 42, and when the large-particle raw materials are pushed out of the feeding hopper 12, the lead screw 41 is reversely rotated, so that the scraper 61 and the baffle 42 are reset, and the raw materials pushed out of the feeding hopper 12 fall into the receiving box 43, so that the raw materials are uniformly collected.

[0037] The large-particle raw materials remaining on the screen plate 23 can be cleaned and collected, the large-particle raw materials accumulated on the screen plate 23 are reduced, the screening effect of the screen plate 23 is not affected, and the screen plate 23 is not blocked.
