Detailed Implementation
[0016] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.
[0017] Combined with appendix Figure 1-3 As shown, a device for preventing bridging during the feeding of modified plastic granules for vehicles includes a fixed frame 2, which includes a central seat 3 and four adjusting seats 4 arranged symmetrically and perpendicularly to each other on the central seat 3. Each adjusting seat 4 is provided with a rotatable lead screw 5 located below the adjusting seat 4 and distributed along its length direction. It also has a handwheel 6 located at the outer end of the lead screw 5 and a connecting seat 7 that is threaded to the lead screw 5 and can slide along the length direction of the adjusting seat 4. The connecting seat 7 is provided with a clamping and fixing mechanism for connecting and fixing the entire fixed frame 2. An arch-breaking mechanism is installed on the central seat 3 and is used to stir the modified plastic granules and break the arch structure formed during feeding.
[0018] It should be noted that the anti-bridging device of this utility model is detachably installed on the upper port of the hopper 1. The connecting seat 7 on the adjusting seat 4 is used to support and match the upper port of the hopper 1. The clamping and fixing mechanism on the connecting seat 7 is used to connect and fix the entire anti-bridging device.
[0019] When adjusting the position of the connecting seat 7, turn the handwheel 6 to drive the lead screw 5 to rotate, which in turn drives the connecting seat 7 to slide along the adjusting seat 4 to the appropriate position.
[0020] The clamping and fixing mechanism includes an outer baffle 9, which is disposed on the outer end of the lower end face of the connecting seat 7; an inner baffle 10, which is disposed on the inner end of the lower end face of the connecting seat 7; a mounting groove 11, which is disposed at the lower end of the connecting seat 7 and has a sliding rod 11a inside; a clamping plate 12, which is slidably mounted on the lower end face of the connecting seat 7 and has its upper end slidingly engaged with the mounting groove 11 and the sliding rod 11a; and an adjusting screw 13, which is mounted on the outer baffle 9 and threadedly engaged with it, has its inner end rotatably connected to the clamping plate 12, and has a lever 13a at its outer end.
[0021] It should be noted that when the clamping and fixing mechanism is clamping and fixing, the adjusting screw 13 is tightened directly by lever 13a, which in turn pushes the clamping plate 12 forward until it clamps the edge of the upper port of the feed hopper 1.
[0022] The lower ends of the inner baffle 10 and the clamping plate 12 are provided with corresponding mounting holes 14. Reinforcing screws 15 are inserted into the mounting holes 14, and reinforcing nuts 15a are provided on the reinforcing screws 15. It should be noted that after the clamping and fixing mechanism is clamped, the corresponding mounting holes 14 need to be drilled on the hopper 1 through the mounting holes on the clamping plate 12. When the reinforcing screws 15 are actually installed, they need to pass through the mounting holes 14 on the clamping plate 12, the hopper 1, and the inner baffle 10 in sequence, and then install and tighten the reinforcing nuts 15a to complete the reinforcement connection, thereby reducing the possibility of loosening.
[0023] The aforementioned arch-breaking mechanism includes a first stirring shaft 16, which is horizontally rotatably mounted on a central seat 3; its upper end is located at the lower end inside the central seat 3 and is provided with a first bevel gear 16a; its lower end extends out from inside the central seat 3 and is provided with a first stirring rod 16b; a second stirring shaft 17, which is horizontally rotatably mounted on the central seat 3; its upper end is located at the upper end inside the central seat 3 and is provided with a second bevel gear 17a; its lower end passes through the first stirring shaft 16 and extends out, and is provided with a second stirring rod 17b; an intermediate bevel gear 18, which is vertically rotatably mounted inside the central seat 3 and simultaneously meshes with the first bevel gear 16a and the second bevel gear 17a; and an arch-breaking motor 19, which is disposed on the upper end face of the central seat 3 and is connected to the second stirring shaft 17 in a transmission manner.
[0024] It should be noted that when the arch-breaking mechanism is working, the arch-breaking motor 19 starts and directly drives the second stirring rod 17b to stir and break up the arches through the second stirring shaft 17; at the same time, the second stirring shaft 17 drives the intermediate bevel gear 18 to rotate through the second bevel gear 17a, the intermediate bevel gear 18 drives the first bevel gear 16a to rotate, and the first bevel gear 16a drives the first stirring rod 16b to stir and break up the arches through the first stirring shaft 16; the stirring and rotation direction of the first stirring rod 16b is opposite to that of the second stirring rod 17b.
[0025] The first stirring rod 16b is detachably mounted on the lower end of the first stirring shaft 16, and the second stirring rod 17b is detachably mounted on the lower end of the second stirring shaft 17. A flange 20 is connected between the first stirring rod 16b and the lower end of the first stirring shaft 16, and a flange 20 is also connected between the second stirring rod 17b and the lower end of the second stirring shaft 17. It should be noted that as the specifications of the hopper 1 change, its upper port diameter and overall depth will change. In order to ensure the arch breaking effect, the first stirring rod 16b and the second stirring rod 17b with appropriate width and depth need to be selected according to the actual specifications of the hopper 1.
[0026] Both sides of the aforementioned connector 7 are provided with scale lines 8 to facilitate the determination of the position of the connector 7; it should be noted that this design allows for a more intuitive determination of the position of the connector 7, thereby facilitating precise control of the position of the connector 7.
[0027] When installing anti-cable tray devices
[0028] First, based on the internal dimensions of the hopper 1, select appropriate widths and depths for the first stirring rod 16b and the second stirring rod 17b, and install them onto the first stirring shaft 16 and the second stirring shaft 17.
[0029] Next, based on the diameter of the upper port of the hopper 1, select a suitable initial installation position for the connecting seat 7 and move it to the designated position;
[0030] Then, align the upper port edge of the hopper 1 and directly insert the entire anti-bridging device, so that the lower ends of each connecting seat 7 are respectively engaged with the corresponding edges of the upper port of the hopper 1.
[0031] Then, adjust each connecting seat 7 gradually at equal intervals until the inner baffle 10 of each connecting seat 7 abuts against the inner wall of the upper port of the hopper 1.
[0032] Then, each clamping and fixing mechanism is controlled in sequence so that its clamping plate 12 clamps the edge of the upper port of the feed hopper 1;
[0033] Finally, through the mounting holes 14 on each clamping plate 12, corresponding mounting holes 14 are drilled on the hopper 1, and the reinforcing screws 15 are inserted to complete the reinforcing connection.
[0034] It should be noted that the positions of each connecting seat 7 should be kept as consistent as possible to ensure that the center of the anti-bridging device is on the central axis of the hopper 1, thereby making the overall operation of the equipment more stable.
[0035] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
