[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-5 This utility model provides a technical solution:
[0026] See Figure 1 and Figure 5 As shown, the molding equipment used for the production of special resin granules includes a box body 1, a feeding port 2 is provided above the box body 1, an installation cavity 3 is connected between the box body 1 and the feeding port 2, a granulation component is provided in the installation cavity 3, a sieving component and a cleaning component are provided in the box body 1, the sieving component includes a sieve plate 12, and the cleaning component includes an outer frame 27 installed on the outside of the sieve plate 12.
[0027] Slide seats 15 are installed on both sides of the outer frame 27. Vertical through grooves are opened in the two slide seats 15. Slide blocks 17 are slidably connected in the through grooves. U-shaped connecting blocks 18 are symmetrically installed on the upper and lower sides of the slide blocks 17. The ends of the two horizontal U-shaped connecting blocks 18 away from the slide blocks 17 are connected to connecting rods 19. Cleaning brushes 20 are installed on the side of the two connecting rods 19 near the sieve plate 12. L-shaped connecting rods 26 are connected to the bottom of the two lower U-shaped connecting blocks 18. A collection chamber 8 is installed below the sieve plate 12. A slot matching the vertical section of the collection chamber 8 is opened on one side of the box body 1. The L-shaped connecting rod 26 is located on the side of the collection chamber 8 away from the slot. One end of the L-shaped connecting rod 26 is fixedly connected to the inner wall of the collection chamber 8.
[0028] In the specific implementation process, the outer frame 27 is fixed to the outside of the sieve plate 12, and vertical through grooves are opened in the sliding seats 15 installed on both sides of it. The slider 17 can slide freely in the through grooves. After the granulation component and the sieving component have finished working, the resin particles will be collected in the collection chamber 8. At this time, the collection chamber 8 is moved out of the box 1 to take out the collected resin particles. When the collection chamber 8 slides, since the U-shaped connecting block 18 is fixedly connected to the collection chamber 8 through the L-shaped connecting rod 26, the slider 17 will slide horizontally in the through groove. The cleaning brush 20 will move on the surface of the sieve plate 12 to remove the resin particles or other impurities attached to the sieve plate 12 and prevent the sieve plate 12 from being blocked. After taking out the resin particles in the collection chamber 8 and cleaning the sieve plate 12, the collection chamber 8 can be pushed back to its original position to continue the next round of production and collection process.
[0029] See Figure 5 As shown, two water pipes 22 are installed on the inner sidewall of the outer frame 27 above the sieve plate 12. These water pipes 22 are symmetrically arranged on the inner sidewall of the outer frame 27. Spray heads 23 are installed on the sidewalls of the water pipes 22. The water pipes 22 are connected to an external connecting pipe 21 that extends to the outside of the housing 1. In practice, an external water source is connected through the external connecting pipe 21, allowing water to flow into the water pipes 22. The water is then evenly sprayed onto the sieve plate 12 through the spray heads 23, washing away the resin particles adhering to the sieve plate 12.
[0030] See Figure 5 As shown, limit strips 16 are installed on the inner wall of the slide block 15. There are four limit strips 16 in the same slide block 15. The two ends of the four limit strips 16 are fixedly connected to the two sides of the slide block 15 and are symmetrically arranged at the four corners of the two sides. In the specific implementation process, the limit strips 16 provide additional support and guidance for the slider 17, making it more stable during sliding, thereby improving the cleaning effect of the cleaning brush 20 on the sieve plate 12.
[0031] See Figure 1 and Figure 2 As shown, the granulation assembly includes a crushing blade 11 installed in the mounting cavity 3. One end of the crushing blade 11 is fixedly connected to the inner wall of the mounting cavity 3, and the other end of the crushing blade 11 is connected to a rotating shaft that passes through the housing 1 and is rotatably connected to the housing 1. A motor 4 is connected to the rotating shaft. A drive sprocket 5 is sleeved on the outer arc wall of the rotating shaft outside the mounting cavity 3. A motor box is installed on the outside of the mounting cavity 3, and the motor 4 is located inside the motor box. In the specific implementation process, the raw material resin is fed into the mounting cavity 3 through the feed port 2. The operator starts the motor 4, and the motor 4 drives the rotating shaft to rotate through the transmission device. As the rotating shaft rotates, the crushing blade 11 begins to cut or crush the raw material resin, gradually processing it into smaller particles. The crushed resin particles are then screened through the sieve plate 12.
[0032] See Figure 1 and Figure 3 As shown, the screening assembly includes a rotating rod 13 installed below the outer frame 27. One end of the rotating rod 13 passes through the outside of the box 1 and is rotatably connected to the box 1. The other end is fitted with a vibrating block 14, which abuts against the bottom surface of the screen plate 12. The vibrating block 14 is semi-circular. A driven sprocket 6 is fixedly connected to one end of the rotating rod 13 outside the box 1. A chain 7 is installed between the driven sprocket 6 and the driving sprocket 5. The driving sprocket 5 and the driven sprocket 6 are connected by the chain 7. In the specific implementation process, when the motor 4 is started, it will drive the drive sprocket 5 to rotate. As the drive sprocket 5 rotates, the chain 7 begins to tighten and drives the driven sprocket 6 to rotate. The rotation of the driven sprocket 6 further drives the rotating rod 13 to rotate. The rotation of the rotating rod 13 causes the vibrating block 14 to generate a reciprocating impact force on the bottom surface of the screen plate 12, causing the screen plate 12 to vibrate. Under the action of vibration, the resin particles gradually pass through the screen holes on the screen plate 12, realizing screening and separation. The screened resin particles are collected in the collection chamber 8 below.
[0033] See Figure 4 As shown, a first spring 24 and a second spring 25 connect the sieve plate 12 and the outer frame 27. The first spring 24 is sleeved around the second spring 25. The two ends of the first spring 24 and the second spring 25 are respectively connected to the outer side wall of the sieve plate 12 and the inner side wall of the outer frame 27, and are symmetrically arranged on both sides of the sieve plate 12. In specific implementation, the first spring 24 sleeved around the second spring 25 forms a composite spring structure, which enhances the elastic support capacity of the spring, improves its stability and durability, helps maintain the balance of the sieve plate 12 during vibration, and avoids problems such as poor screening effect or equipment damage caused by uneven force.
[0034] See Figure 1As shown, a handle 9 is installed on the side of the collection bin 8 near the opening, and symmetrical protrusions 10 are connected to both sides of the collection bin 8. The housing 1 has horizontal grooves that match the protrusions 10. In practice, the handle 9 on the side of the collection bin 8 near the opening allows the operator to easily grasp the handle 9 to move or remove the collection bin 8 from the housing 1. The matching design of the protrusions 10 and the grooves ensures the stable fixation of the collection bin 8 within the housing 1, preventing it from shaking or falling off during the vibration screening process.
[0035] Working principle:
[0036] Step 1: Raw resin is fed into the installation cavity 3 through the feed port 2. The operator starts the motor 4, which drives the rotating shaft to rotate through the transmission device. As the rotating shaft rotates, the crushing blade 11 begins to cut or crush the raw resin, gradually processing it into smaller particles. The crushed resin particles fall onto the screen plate 12. At the same time, the drive of the motor 4 also drives the rotation of the drive sprocket 5. As the drive sprocket 5 rotates, the chain 7 tightens and drives the driven sprocket 6 to rotate. The rotation of the driven sprocket 6 further drives the rotating rod 13 to rotate. The vibrating block 14 on the rotating rod 13 generates a reciprocating impact force on the bottom surface of the screen plate 12, causing the screen plate 12 to vibrate. Under the action of vibration, the resin particles gradually pass through the screen holes on the screen plate 12, realizing screening and separation.
[0037] Step 2: After the granulation and sieving components have finished working, the operator moves the collection bin 8 out of the housing 1 to remove the resin particles. At this time, since the U-shaped connecting block 18 is fixedly connected to the collection bin 8 through the L-shaped connecting rod 26, the movement of the collection bin 8 will drive the slider 17 to slide horizontally in the through groove of the slide block 15. The cleaning brush 20 then moves on the surface of the sieve plate 12 to remove the resin particles or other impurities attached to the sieve plate 12 and prevent the sieve plate 12 from clogging. In order to further improve the cleaning effect of the sieve plate 12, the operator can connect an external water source through the external pipe 21 to let the water flow into the water pipe 22. The water is evenly sprayed onto the sieve plate 12 through the spray head 23 to wash away the resin particles attached to the sieve plate 12.
