Description

Technical Field

[0001] This utility model relates to the field of conveying devices, specifically a raw material conveying device for plastic granulation. Background Technology

[0002] Plastic granulation is a process in plastic machinery processing. In the process of plastic granulation, it is necessary to explore and master the skills based on the performance of the machine and practical experience in order to continuously improve the quality and process of plastic products. Plastic granulation requires the use of a plastic granulator, and the use of a plastic granulator requires a raw material conveying device to transport the raw material to the feeding port. Different conveying devices are used for different raw materials.

[0003] When conveying granular raw materials, a screw conveyor is required. Existing raw material conveying devices for plastic granulation require manual handling of the raw material bags, opening them, and then manually pouring the raw material bags vertically into the hopper. However, this method requires the person to hold the raw material bag continuously, and when the raw material in the bag gradually decreases, it needs to be removed by hand. This method is time-consuming, labor-intensive, and quite troublesome. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a raw material conveying device for plastic granulation, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material conveying device for plastic granulation, comprising a base, a conveying pipe installed above the base, and a discharge port provided at the end of the conveying pipe, a spiral conveying shaft installed inside the discharge port, and a motor installed at the end of the spiral conveying shaft, an inlet opening on the outer wall of the conveying pipe, a hopper fixed to the outer wall of the conveying pipe, and a movable plate movably installed on the inner wall of the hopper, two sets of hydraulic rods movably installed on one side of the hopper, and the ends of the hydraulic rods movably installed with the bottom of the movable plate, and a limit post fixed to the top of the movable plate, the limit post being tapered.

[0006] By adopting the above technical solution, the problem of needing personnel to hold the bag when adding granular raw materials is solved. When adding raw materials, simply open the bag, then throw the open opening into the hopper, place the bag above the movable plate, and the conical limiting post will puncture the bag. Because the movable plate is tilted, the raw materials in the bag will pour into the hopper. Then, activate the hydraulic rod, which will change the angle of the movable plate, and the raw materials in the bag will gradually enter the hopper. The problem of personnel constantly holding the bag to add raw materials to the hopper is eliminated.

[0007] The present invention is further configured such that a movable rod is movably installed inside the hopper, and multiple sets of levers are fixed to the outer wall of the movable rod; a fixed rod is fixed to the end of the movable plate; and the fixed rod and the movable rod are connected by a transmission assembly; the transmission assembly includes a first pulley fixed to the end of the fixed rod; a second pulley is fixed to the end of the movable rod; and a belt is sleeved between the second pulley and the first pulley.

[0008] By adopting the above technical solution, the hydraulic rod is then activated. The hydraulic rod drives the movable plate to rotate around the fixed rod, thus changing the angle of the movable plate. When the angle of the movable plate changes, the tilt angle of the raw material bag increases, so the raw material will slide down under its own gravity. When the angle of the movable plate changes, it drives the movable rod to rotate through the transmission component. The first pulley drives the second pulley to rotate through the belt. When the second pulley rotates, it drives the movable rod to rotate. When the movable rod rotates, it drives the paddle block to rotate. The rotation of the paddle block will disperse the raw material accumulated at the feed inlet, thereby preventing the raw material from accumulating.

[0009] The present invention is further configured such that multiple sets of support rods are fixed on one side of the hopper, and the multiple sets of support rods are evenly distributed on one side of the hopper.

[0010] By adopting the above technical solution, the multiple sets of support rods can support the movable plate, avoiding the problem of deformation of the movable plate due to force when the raw material bag is placed on top of the movable plate.

[0011] The present invention is further configured such that side baffles are fixed on both sides of the movable plate, and the movable plate extends into the interior of the hopper.

[0012] By adopting the above technical solution, the side baffle can prevent raw materials from falling off when they are scattered above the movable plate.

[0013] The present invention is further configured such that a mounting rod is fixed on one side of the hopper, and the mounting rod is connected to the movable rod bearing.

[0014] By adopting the above technical solution, the installed rod can provide force support for the movable rod, so that the movable rod will not easily wobble when rotating, making the rotation of the movable rod more stable.

[0015] The present invention is further configured such that the number of limiting posts is three sets, and the multiple sets of limiting posts are triangularly distributed on the top of the movable plate, and the movable plate is inclined.

[0016] By adopting the above technical solution, the three sets of limiting posts can conveniently limit the raw material bag. When the raw material bag is punctured, the three sets of limiting posts can increase the friction between the raw material bag and the limiting post. When the angle of the movable plate changes, the raw material bag will stay on one side of the movable plate and will not fall off.

[0017] The present invention is further configured such that multiple sets of omnidirectional wheels are installed at the bottom of the base, and the multiple sets of omnidirectional wheels are evenly distributed at the bottom of the base.

[0018] By adopting the above technical solution, the device can be easily pushed to the designated position using the omnidirectional wheels, thereby achieving the purpose of feeding.

[0019] In summary, the present invention has the following beneficial effects:

[0020] 1. This utility model, by incorporating a hopper, a movable plate, a limiting post, and a hydraulic rod, solves the problem of requiring personnel to hold the bag when adding granular raw materials. When adding raw materials, simply open the bag, then place the opening into the hopper, and place the bag above the movable plate. The conical limiting post punctures the bag, and because the movable plate is tilted, the raw materials inside the bag will pour into the hopper. Then, activate the hydraulic rod, which changes the angle of the movable plate, allowing the raw materials inside the bag to gradually enter the hopper. This eliminates the need for personnel to continuously hold the bag while adding raw materials to the hopper.

[0021] 2. This utility model solves the problem of material blockage during addition by incorporating a movable rod, a lever, a transmission assembly, and a support rod. When the angle of the movable plate changes, the transmission assembly drives the movable rod to rotate, and the lever rotates accordingly, which disperses the material blocking the feed inlet and prevents accumulation. The support rod provides force support to the movable plate when the raw material bag is placed on top of it, preventing the movable plate from tipping over. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] A raw material conveying device for plastic pelletizing, such as Figure 1 - Figure 5 As shown, the system includes a base 1, a conveying pipe 2 mounted on top of the base 1, and a discharge port 21 at the end of the conveying pipe 2. A screw conveyor shaft 23 is installed inside the discharge port 21, and a motor 22 is mounted at the end of the screw conveyor shaft 23. An inlet 24 is opened on the outer wall of the conveying pipe 2, and a hopper 3 is fixed to the outer wall of the conveying pipe 2. A movable plate 4 is movably mounted on the inner wall of the hopper 3. A raw material bag is placed on top of the movable plate 4, with the opening of the raw material bag located inside the hopper 3. When the raw material bag is placed on top of the movable plate 4, a conical limiting post 5 punctures the raw material bag. Because the movable plate 4 is tilted, when the raw material... When the bag is placed above the movable plate 4, the raw material falls into the hopper 3. Two sets of hydraulic rods 8 are movably installed on one side of the hopper 3, and the ends of the hydraulic rods 8 are movably installed with the bottom of the movable plate 4. The top of the movable plate 4 is fixed with a limit post 5, and the limit post 5 is set as a cone. Then the hydraulic rods 8 are activated, and the hydraulic rods 8 work to drive the movable plate 4 to rotate around the fixed rod 41 as the center. Therefore, the angle of the movable plate 4 changes. When the angle of the movable plate 4 changes, the tilt angle of the raw material bag becomes larger, so the raw material will slide down under its own gravity. The larger the tilt angle of the movable plate 4, the faster the raw material falls inside the bag.

[0031] See also Figures 2-5The hopper 3 has a movable rod 7 installed inside, and multiple sets of levers 71 are fixed to the outer wall of the movable rod 7. The end of the movable plate 4 is fixed with a fixed rod 41, and the fixed rod 41 is connected to the movable rod 7 through a transmission assembly 6. The transmission assembly 6 includes a first pulley 61 fixed to the end of the fixed rod 41, a second pulley 62 fixed to the end of the movable rod 7, and a belt 63 is sleeved between the second pulley 62 and the first pulley 61. Then, the hydraulic rod 8 is activated, and the hydraulic rod 8 drives the movable plate 4 to rotate around the fixed rod 41. Therefore, the angle of the movable plate 4 changes. When the angle of the movable plate 4 changes, the tilt angle of the raw material bag increases, so the raw material will slide down under its own weight. When the angle of the movable plate 4 changes, the movable rod 7 is driven to rotate through the transmission assembly 6. The first pulley 61 drives the second pulley 62 to rotate through the belt 63. When the second pulley 62 rotates, it drives the movable rod 7 to rotate. When the movable rod 7 rotates, it drives the levers 71 to rotate. The rotation of the levers 71 will disperse the raw material accumulated at the feed inlet 24, thereby preventing the raw material from accumulating.

[0032] See also Figure 3 Multiple sets of support rods 31 are fixed on one side of the hopper 3. The multiple sets of support rods 31 are evenly distributed on one side of the hopper 3. The multiple sets of support rods 31 can support the movable plate 4, so as to avoid the problem of deformation of the movable plate 4 due to force when the raw material bag is placed on top of the movable plate 4.

[0033] See also Figure 3 and Figure 4 Side baffles 42 are fixed on both sides of the movable plate 4, and the movable plate 4 extends into the interior of the hopper 3. The side baffles 42 can prevent raw materials from falling when they are scattered above the movable plate 4.

[0034] See also Figure 3 A mounting rod 32 is fixed on one side of the hopper 3, and the mounting rod 32 is connected to the movable rod 7 by a bearing. The mounting rod 32 can provide force support for the movable rod 7, so that the movable rod 7 will not easily shake when rotating, making the rotation of the movable rod 7 more stable.

[0035] See also Figure 4 There are three sets of limiting posts 5, which are triangularly distributed on the top of the movable plate 4. The movable plate 4 is set at an angle. The three sets of limiting posts 5 can conveniently limit the raw material bag. When the raw material bag is punctured, the three sets of limiting posts 5 can increase the friction between the raw material bag and the plate. When the angle of the movable plate 4 changes, the raw material bag will not fall to one side of the movable plate 4.

[0036] See also Figure 1 and Figure 2The bottom of the base 1 is equipped with multiple sets of casters 9, which are evenly distributed on the bottom of the base 1. The casters 9 can be used to easily push the device to the designated position, thereby achieving the purpose of feeding.

[0037] The working principle of this utility model is as follows: When in use, the device is pushed to the designated position, then the motor 22 is turned on, and then the raw material bag is opened and placed above the movable plate 4. The opening of the raw material bag is located inside the hopper 3. When the raw material bag is placed above the movable plate 4, the conical limiting post 5 punctures the raw material bag. Because the movable plate 4 is tilted, when the raw material bag is placed above the movable plate 4, the raw material falls into the hopper 3. The raw material then enters the conveying pipe 2 through the feed inlet 24 and is conveyed under the action of the screw conveyor shaft. Then, the hydraulic rod 8 is activated, and the hydraulic rod 8 drives the movable plate 4 to rotate around the fixed rod 41. The angle of the movable plate 4 is changed. When the angle of the movable plate 4 changes, the tilt angle of the raw material bag increases, so the raw material will slide down under its own weight. When the angle of the movable plate 4 changes, the transmission component 6 drives the movable rod 7 to rotate. The first pulley 61 drives the second pulley 62 to rotate through the belt 63. When the second pulley 62 rotates, it drives the movable rod 7 to rotate. When the movable rod 7 rotates, it drives the paddle block 71 to rotate. The rotation of the paddle block 71 will disperse the raw material accumulated at the feed inlet 24, thereby avoiding the accumulation of raw material. The greater the tilt angle of the movable plate 4, the faster the raw material inside the raw material bag falls. When the raw material inside the raw material bag is emptied, the raw material bag is removed and the hydraulic rod 8 is reset.
