Abstract
Description
Technical Field
[0001] This utility model belongs to the field of raw material transfer technology for plastic products, specifically a raw material transfer device for plastic product production. Background Technology
[0002] In the production process of plastic products, raw materials such as plastic granules, powders or liquids usually need to be stored and transported through transfer devices, so a raw material transfer device for plastic product production is proposed.
[0003] Existing plastic raw materials are usually in granular form. When transporting plastic raw materials to the next place of use, personnel usually place the plastic raw materials in a collection bucket, then place the collection bucket on a transport vehicle to transport to the place of use. After arriving at the site, it is necessary to manually empty the collection bucket to pour out the raw materials inside, thereby realizing the transfer of plastic product raw materials.
[0004] However, existing transfer devices still have some problems. Because plastic raw materials are prone to residue and clumping, and some raw materials are adhesive, residues can easily accumulate inside the transfer device. Residues of different colors or materials can cause contamination of subsequent batches of products, thereby affecting the production quality of plastic products. Therefore, a raw material transfer device for plastic product production is proposed to address the above problems. Utility Model Content
[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a raw material transfer device for plastic product production.
[0006] The technical solution adopted by this utility model to solve its technical problem is a raw material transfer device for plastic product production, including: a transfer tank, a PLC controller installed on the transfer tank, a drive motor installed on the top of the transfer tank, a connecting shaft fixedly connected to the output end of the drive motor, the connecting shaft being located inside the transfer tank, limit grooves symmetrically formed inside the connecting shaft, limit blocks slidably connected inside the limit grooves, a spring fixedly connected to the inner wall of the connecting shaft, an extension plate fixedly connected to one end of the spring, the extension plate slidably connected inside the connecting shaft, the upper and lower sides of the extension plate being fixedly connected to two sets of limit blocks respectively, and a scraper and cleaning bristles fixedly connected to one side of the extension plate. When the drive motor is started, it drives the connecting shaft to rotate, and the resulting centrifugal force throws the extension plate outward, causing the scraper and cleaning bristles to adhere to the inner wall of the transfer tank. Under the drive of the drive motor, residual and adhered plastic raw materials on the inner wall of the transfer tank can be scraped off, leaving the inner wall of the transfer tank clean.
[0007] Preferably, a feed inlet is installed on the upper part of one side of the transfer tank, and a discharge outlet is installed on the lower part of one side of the transfer tank. Both the feed inlet and the discharge outlet are equipped with control valves. The control valves control the opening and closing of the feed inlet and the discharge outlet, thereby ensuring the sealing of the transfer tank when transferring plastic product raw materials and preventing the raw materials from falling out of the transfer tank.
[0008] Preferably, the transfer tank has a discharge trough inside, and the transfer tank has through holes at the top and bottom. A sealing plug is movably connected inside the through hole to seal the top and bottom through holes, thereby preventing the desiccant from spilling out of the discharge trough.
[0009] Preferably, a damping pad is fixedly connected to one side of the sealing plug, the damping pad is in contact with the inner wall of the discharge trough, and a filter screen is fixedly connected inside the transfer tank. The filter screen separates the desiccant and the plastic product raw materials to avoid contamination of the plastic raw materials.
[0010] Preferably, the bottom of the transfer tank is equipped with four sets of universal wheels, and a connecting plate is fixedly connected to the vertical shaft of the universal wheels. By pushing the transfer tank, the four sets of universal wheels at the bottom are rotated under force, and the transfer tank can be pushed to the designated position.
[0011] Preferably, an electric telescopic rod is fixedly connected to one side of the connecting plate, and a friction block is fixedly connected to the telescopic end of the electric telescopic rod. The PLC controller is electrically connected to the drive motor, control valve, and electric telescopic rod. When the electric telescopic rod is activated, the friction block is pushed towards the universal wheel, making the two stick together. The universal wheel is restricted by the friction block and is in a stopped state, thereby preventing the transfer tank from moving due to external force and ensuring accurate docking between the unloading port and the receiving equipment.
[0012] The advantages of this invention are as follows: when the drive motor is started, it drives the connecting shaft to rotate, and the resulting centrifugal force throws the extension plate outward, causing the scraper and cleaning bristles to adhere to the inner wall of the transfer tank. Driven by the drive motor, the residual and adhered plastic raw materials on the inner wall of the transfer tank can be scraped off, keeping the inner wall of the transfer tank clean. This avoids cross-contamination of various raw materials during the subsequent transfer of different plastic product raw materials, which could affect the production of plastic products.
[0013] When the transfer tank is in the designated position, the electric telescopic rod is activated to push the friction block towards the universal wheel, making the two stick together. The universal wheel is restricted by the friction block and stops rotating, thereby preventing the transfer tank from moving due to external forces. This ensures that the unloading port is accurately connected to the receiving equipment, avoids material spillage or uneven conveying caused by tank shaking, and improves the stability and accuracy of the unloading of the transfer device.

[0021] 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 scope of protection of the present utility model.
[0022] Please see Figure 1-5 As shown, a raw material transfer device for plastic product production includes: a transfer tank 1, a PLC controller 2 installed on the transfer tank 1, a drive motor 3 installed on the top of the transfer tank 1, a connecting shaft 4 fixedly connected to the output end of the drive motor 3, the connecting shaft 4 being located inside the transfer tank 1, limit grooves 5 symmetrically opened inside the connecting shaft 4, limit blocks 6 slidably connected inside the limit grooves 5, a spring 7 fixedly connected to the inner wall of the connecting shaft 4, an extension plate 8 fixedly connected to one end of the spring 7, the extension plate 8 slidably connected inside the connecting shaft 4, the upper and lower sides of the extension plate 8 being fixedly connected to two sets of limit blocks 6 respectively, and a scraper 9 and cleaning bristles 901 fixedly connected to one side of the extension plate 8;
[0023] In the production of plastic products, raw materials such as plastic granules, powders, or liquids usually need to be stored and transported through transfer devices. Because plastic raw materials are prone to residue and clumping, and some materials are adhesive, residues easily accumulate inside the transfer device. Residues of different colors or materials can contaminate subsequent batches of products. Therefore, a raw material transfer device for plastic product production is needed. In actual use, after the raw material in transfer tank 1 is discharged from outlet 11, when other raw materials need to be transferred, the PLC controller 2 is electrically connected to the drive motor 3. The PLC controller 2 starts the drive motor 3, causing the connecting shaft 4 to rotate. The resulting centrifugal force throws the extension plate 8 outwards, simultaneously causing the upper and lower limit blocks 6 to move synchronously along the limit grooves 5, and simultaneously stretching the spring 7, so that the scraper 9 and cleaning brush bristles 901 are in contact with the transfer tank 1. The inner walls of the transfer tank 1 are in contact, so that under the drive of the drive motor 3, the residual and adhered plastic raw materials on the inner wall of the transfer tank 1 can be scraped off. While cleaning, cleaning water can be added into the transfer tank 1 through the feed port 10, so that the cleaning water and residue can be discharged out through the discharge port 11, thereby improving the cleaning intensity of the transfer tank 1. If there is a lot of cleaning water left in the transfer tank 1, the fan can blow air into the transfer tank 1 to improve the dryness of the transfer tank 1 and avoid affecting the transfer quality of plastic products. After cleaning, the drive motor 3 is turned off, the connecting shaft 4 stops rotating, the centrifugal force generated disappears, the tension on the spring 7 decreases, and the extension plate 8 is driven into the interior of the connecting shaft 4 by the contraction of the spring 7's own elasticity, which can reduce the occupation of the internal space of the transfer tank 1 and thus avoid affecting the amount of plastic product raw materials transferred.
[0024] Please see Figure 1-5 As shown, a feed inlet 10 is installed on the upper part of one side of the transfer tank 1, and a discharge outlet 11 is installed on the lower part of one side of the transfer tank 1. Both the feed inlet 10 and the discharge outlet 11 are equipped with control valves 12. A discharge trough 13 is opened inside the transfer tank 1. Through holes are opened at the top and bottom of the transfer tank 1. A sealing plug 14 is movably connected inside the through hole. A damping pad 15 is fixedly connected to one side of the sealing plug 14. The damping pad 15 is in contact with the inner wall of the discharge trough 13. A filter screen 16 is fixedly connected inside the transfer tank 1. Four sets of universal wheels 17 are installed at the bottom of the transfer tank 1. A connecting plate 18 is fixedly connected to the vertical shaft of the universal wheel 17. An electric telescopic rod 19 is fixedly connected to one side of the connecting plate 18. A friction block 20 is fixedly connected to the telescopic end of the electric telescopic rod 19. The PLC controller 2 is electrically connected to the drive motor 3, the control valve 12 and the electric telescopic rod 19.
[0025] Before transferring the plastic product raw materials, remove the sealing plug 14 from the top of the transfer tank 1 and add desiccant to the discharge trough 13. After adding, put the sealing plug 14 and damping pad 15 back into the opening at the top of the transfer tank 1. In conjunction with the two sets of control valves 12, seal the transfer tank 1. During the transfer process, the PLC controller 2 drives the drive motor 3 to run at regular intervals. This allows the raw materials in the transfer tank 1 to be agitated at regular intervals through the connecting shaft 4 and the extension plate 8. In conjunction with the desiccant, the strength of the desiccant's absorption of moisture in the transfer tank 1 through the filter screen 16 is improved, thereby increasing the dryness inside the transfer tank 1. The filter screen 16 separates the desiccant from the plastic product raw materials, preventing contamination of the plastic raw materials. The desiccant needs to be replaced regularly. Pull the sealing plug 14 and damping pad 15 at the bottom of the transfer tank 1 downwards to allow the bottom through hole of the discharge trough 13 to be exposed, so that the desiccant inside the discharge trough 13 can be discharged outwards for replacement.
[0026] The PLC controller 2 opens the control valve 12 on the feed inlet 10, allowing the plastic raw material to be transferred to be placed into the transfer tank 1. Then, the control valve 12 is closed, sealing the transfer tank 1. Pushing the transfer tank 1 causes the four sets of casters 17 at its bottom to rotate, thus moving the transfer tank 1 to the designated position, thereby transferring the plastic raw material. Once the transfer tank 1 is in the designated position, the PLC controller 2 activates the electric telescopic rod 19, pushing the friction block 20 against the casters 17, ensuring they are in close contact. This increases the friction on the casters 17, allowing the casters to move more efficiently. When the rotation of wheel 17 stops, the position of the transfer tank 1 is fixed. The control valve 12 on the discharge port 11 is opened by the PLC controller 2, so that the discharge port 11 is in an open state, allowing the plastic product raw material in the transfer tank 1 to be discharged from the transfer tank 1, thereby completing the transfer. When the plastic product raw material is discharged from the transfer tank 1, the universal wheel 17 is stopped by the friction block 20, thereby preventing the transfer tank 1 from being moved by external forces. This ensures that the discharge port is accurately connected to the receiving equipment, avoids the spillage or uneven conveying of raw materials due to tank shaking, and thus improves the stability and accuracy of the unloading of the transfer device.
[0027] Working principle: Before transferring plastic product raw materials, remove the sealing plug 14 from the top of the transfer tank 1, add desiccant to the discharge trough 13, and after adding, put the sealing plug 14 and damping pad 15 back into the opening at the top of the transfer tank 1. This, in conjunction with the two sets of control valves 12, seals the transfer tank 1. The control valve 12 on the feed inlet 10 is opened via the PLC controller 2, allowing the plastic product raw materials to be transferred to be placed into the transfer tank 1. Then, the control valve 12 is closed, pushing the transfer tank 1 so that the four sets of universal wheels 17 at its bottom rotate under force, thus pushing the transfer tank 1 to the designated position, thereby realizing the transfer of plastic product raw materials. The electric telescopic rod 19 is activated via the PLC controller 2, pushing the friction block 20 against the universal wheels 17, ensuring they are in close contact, causing the universal wheels 17 to stop rotating. The position of the transfer tank 1 can be fixed by the movement of the transfer tank 1, which can prevent the transfer tank 1 from being moved by external forces. This can ensure that the unloading port is accurately connected to the receiving equipment, and improve the stability and accuracy of the unloading of the transfer device. After the unloading is completed, the drive motor 3 is started by the PLC controller 2 to drive the connecting shaft 4 to rotate. The centrifugal force generated will throw the extension plate 8 outward, so that the scraper 9 and cleaning bristles 901 are attached to the inner wall of the transfer tank 1. Thus, under the drive of the drive motor 3, the residual and adhered plastic raw materials on the inner wall of the transfer tank 1 can be scraped off. At the same time, cleaning water can be added into the transfer tank 1 through the feed port 10, and the cleaning water and residues can be discharged outward through the discharge port 11, thereby improving the cleaning intensity of the transfer tank 1 and avoiding cross-contamination during the subsequent transfer of different plastic product raw materials.
