Description

Technical Field

[0001] The utility model belongs to the technical field of feeding devices, in particular to a double-arc feeding device. Background Art

[0002] Roller presses are commonly used for crushing materials, particularly those subject to high abrasion, such as ore, cement clinker, slag, or ceramic raw materials. Roller presses consist of fixed and movable rollers. The movable rollers are movable relative to the fixed rollers, meaning they can be adjusted with a variable gap width relative to the fixed rollers. To this end, the movable rollers can be adjusted relative to the fixed rollers via force-generating devices (e.g., hydraulically and / or pneumatically) and are thus supported like hydropneumatic springs. For twin-roller presses, a dual-arc feeder is installed above the rotating rollers, feeding material into the gap between the rollers.

[0003] The double-arc boosting feeding device for a roller press, with publication number CN221156878U, mainly improves the density and stability of the material in the roller press through the double-arc boosting feeding device. Specifically, the device includes a first boosting roller and a second boosting roller, which are respectively installed on both sides of the feed pipe of the roller press and are located above the extrusion roller of the roller press. Two driving members are used to drive the rotation of the first boosting roller and the second boosting roller. The rotation direction of the side where the first boosting roller and the second boosting roller are close to each other is the direction from the feed port of the feed pipe to the discharge port. The pressure control member is used to control the pressure between the first boosting roller and the second boosting roller and the material passing through. The pressure control member acts on the first boosting roller.

[0004] The existing technology has at least the following problems during use:

[0005] In the existing feeding device, materials of different particle sizes may push the rotating rollers during use, causing the gap between the pushed rotating rollers to become larger in a short period of time. Although the rotating rollers can automatically restore the original feeding spacing, during the period when the roller gap is abnormal, the materials will still quickly gather at the roller gap, thereby continuously filling the abnormal roller gap, causing the roller shaft to be unable to return to the original position, thereby affecting the feeding efficiency and the normal operation of the equipment.

[0033] Example:

[0034] Please refer to Figures 1 to 8As shown, this embodiment provides an extruder positioning and calibration device, comprising: a mounting base 1, a feeding tube 2, an adjustment component 6, a driving component 5, and two correcting plates 8. The mounting base 1 is used to be mounted on the roller press; the feeding tube 2 is arranged inside the mounting base 1, and the feeding tube 2 has a first channel, the two ends of the first channel are aligned with the two ends of the roller shaft 3, and the first channel is used to guide the material into the roller press; the adjustment component 6 is installed in the mounting base 1, and is used to control the flow in the first channel; the driving component 5 is connected to the adjustment component 6 in a transmission manner, and is used to drive the adjustment component 6; the correcting plate 8 has a rotating shaft, which is rotatably mounted at the mouth of the first channel. The correcting plate 8 rotates toward the inside of the first channel along the axial direction of the roller shaft 3 to reduce the material flow at the corresponding mounting position.

[0035] In this embodiment, if Figure 1 As shown, the mounting base 1 is a square shell with two sets of fixed plates arranged on both sides. Each set of fixed plates is composed of two fixed plates, and a rib is provided between the fixed plates and the outer wall of the mounting base 1. The mounting plates are mainly used for bolting to the upper surface of the roller press to improve the structural strength of the mounting base 1 and reduce the mutual friction and vibration between the feeding device and the roller press caused by the operation of the equipment. The feeding pipe 2 is a square tube that is inserted into the mounting base 1. There is a roller gap between the two roller shafts 3 of the roller press. The first channel in the feeding pipe 2 is located above the roller gap and is used to transport material from the first channel to the roller gap. The adjustment component 6 is arranged at one end of the first channel near the roller gap and is used to adjust the flow of material output from the first channel, thereby improving the control accuracy of the feed. A side wall plate is provided in the feeding pipe 2 along the distribution direction of the roller gap. The direction along the distribution direction of the roller gap is the first direction, and the direction perpendicular to the distribution direction of the roller gap is the second direction. A bottom plate is provided between the two side wall plates, and a rotation groove is provided on the bottom plate. The correcting plate 8 is rotatably provided in the rotation groove, and the correcting plate 8 rotates in a direction parallel to the roller gap. When large particles pass through the roller gap, they will push the movable roller to cause the roller gap to be uneven, with one side being larger. In the process of returning the relative position between the roller shafts 3, the material will accumulate rapidly, thereby reducing the efficiency of the feeding device and even causing abnormal operation of the equipment. At this time, by adjusting the correcting plate 8, the material in the first channel is guided to bypass the abnormal side of the roller gap, thereby reducing the accumulation of the material and quickly correcting the material, thereby reducing the difficulty of subsequent feeding. The correcting structure is simple, the operation is easier, and the maintenance efficiency is improved.

[0036] Furthermore, in some implementations of this embodiment, Figures 2 to 8As shown, the adjusting assembly 6 comprises: a flow adjusting plate 61, a positioning shaft 62, a guide pressing plate 7, and a supporting wheel 10. The flow adjusting plate 61 is slidingly installed in the first channel, and the flow adjusting plate 61 is provided with a guide groove on a side away from the first channel; the positioning shaft 62 is installed on both sides of the flow adjusting plate 61; the guide pressing plate 7 is installed on the mounting seat 1, and the guide pressing plate 7 is provided with a guide groove, and the positioning shaft 62 is slidingly arranged in the guide groove; and the supporting wheel 10 is installed on the mounting seat 1 and provided with a force bearing arm 11, and the supporting wheel 10 is rotationally arranged on the force bearing arm 11 and is clamped in the guide groove.

[0037] In the embodiment, as shown in Figure 1 the flow adjusting plate 61 is a two-part folding plate comprising an inclined plate and a vertical plate, the positioning shaft 62 is installed on both sides of the inclined plate, the first inner plate is installed on the inclined plate, the second inner plate is installed on the vertical plate, the edge of the first inner plate is slightly longer than the surface of the second inner plate in vertical projection, so as to avoid the impact of the material on the bending part during use of the flow adjusting plate 61, thereby improving the strength and service life of the structure, and the guide groove has two parallel distribution on the back of the flow adjusting plate 61, and correspondingly, the supporting wheel 10 and the force bearing arm 11 installed on both sides of the mounting seat 1 also have two respectively for the movement direction of the flow adjusting plate 61. The guide pressing plate 7 is distributed at both ends of the positioning shaft 62 for preventing the edge of the flow adjusting plate 61 from being raised, improving the control accuracy and the reliability of the movement.

[0038] Further, in some embodiments of the embodiment, as shown in Figures 2 to 8 the guide groove is an arc-shaped groove, one end of the flow adjusting plate 61 makes nonlinear sliding along the guide groove, and the supporting wheel 10 provides support to the back of the flow adjusting plate 61, so that the end of the flow adjusting plate 61 makes arc motion along the roller surface of the pressure roller.

[0039] In the embodiment, as shown in Figure 3 the guide groove is an arc-shaped groove, so as to control the lower surface of the vertical plate of the flow adjusting plate 61 to move along the surface of the roller shaft 3, thereby reducing the distance between the end of the flow guide plate and the roller gap, reducing the back material, reducing the wear of the equipment caused by the material splashing, etc.

[0040] Further, in some embodiments of the embodiment, as shown in Figures 2 to 8 the driving assembly 5 comprises: a frame 51, a plurality of support frames 52, a plurality of driving members 53, and a telescopic rod 54. The frame 51 is installed on the mounting seat 1; the plurality of support frames 52 are installed on the frame 51; the plurality of driving members 53 are correspondingly installed on the support frames 52; one end of the telescopic rod 54 is fixed on the driving member 53, and the other end is hingedly connected with a side of the flow adjusting plate 61 away from the first channel.

[0041] In the embodiment, as shown in Figure 2As shown, the frame 51 is provided to support the installation of the support frame 52, thereby facilitating the relative arrangement of two driving members 53 on both sides of the mounting seat 1. Specifically, the driving member 53 includes a servo motor, a speed reducer, a shaft coupling and a series of transmission components, thereby controlling and driving the telescopic rod 54. The output end of the telescopic rod 54 is arranged to push the flow regulating plate 61. Specifically, the output end of the telescopic rod 54 is provided with a rotating seat, which is rotatably arranged on the back of the flow regulating plate 61 through a rotating shaft with a positioning pin hole.

[0042] Further, in some embodiments of the present embodiment, as shown in Figures 2 to 8 The side baffle 4 is installed on both sides of the mounting seat 1 and corresponds to the two ends of the roller shaft 3. The expansion plate is installed at one end of the first channel near the roller shaft 3 and abuts against the inner wall of the side baffle 4. Two adjusting holes are formed in the mounting seat 1, and the adjusting nuts are threadedly connected with the adjusting holes. One end of the adjusting nut near the first channel abuts against the deviation correcting plate 8, thereby adjusting the rotation angle of the deviation correcting plate 8.

[0043] In the present embodiment, as shown in Figure 3 The expansion plate is arranged at the two ends of the roller shaft 3 and is arranged in parallel with the arc surface of the roller shaft 3, thereby sealing the two sides of the roller gap of the roller press and preventing the material from falling off. The side baffle 4 is arranged outside the expansion plate to further improve the connection strength between the mounting seat 1 and the expansion plate. The two side baffles 4 are fixed to the mounting seat 1 by buckles and latches.

[0044] Further, in some embodiments of the present embodiment, as shown in Figures 5 to 8 The driving assembly 5 further includes a bearing 63 and a bearing sleeve 64. The bearing 63 is sleeved on the positioning shaft 62, and the bearing sleeve 64 is installed between the frame 51 and the bearing 63.

[0045] In the present embodiment, as shown in Figures 5 to 8 The bearing 63 is installed in the bearing sleeve 64 by a circlip, thereby improving the movement stability of the flow regulating plate 61 and reducing the possibility of the flow regulating plate 61 being stuck during driving.

[0046] Further, in some embodiments of the present embodiment, as shown in Figure 2 The side away from the rotating shaft of the deviation correcting plate 8 is a V-shaped edge, which is driven by the adjusting nut to rotate around the rotating shaft and guide the deviation of the material.

[0047] In the present embodiment, as shown in Figure 2 The lower end surface of the deviation correcting plate 8 is a symmetrically arranged V-shaped edge, and the included angle between the two inclined edges and the center axis is the same as the inclination angle of the inclined plate arranged on the flow regulating plate 61 on both sides, thereby preventing the deviation correcting plate 8 from being stuck with the flow regulating plate 61 when the flow regulating plate 61 is closed.

[0048] Furthermore, in some implementations of this embodiment, Figure 2 As shown, two flow regulating plates 61 slide along the guide grooves on both sides respectively, so as to adjust the flow cross-section size of the material in the first channel.

[0049] In this embodiment, if Figure 2 As shown, the two flow regulating plates 61 move in a direction perpendicular to the roller gap, thereby reducing the gap between the two flow regulating plates 61, thereby changing the material flow cross-sectional area at the outlet of the first channel, and cooperating with the correcting plate 8, further reducing equipment abnormalities caused by material accumulation.

[0050] To sum up, when in use, the servo motor can be started so that the output end of the servo motor drives the telescopic rod 54 to move the flow regulating plate 61, and the flow regulating plate 61 moves obliquely back and forth in the direction limited by the supporting wheel 10 and the guide pressure plate 7. Since the contact surface of the guide pressure plate 7 and the bearing sleeve 64 on the flow regulating plate 61 is an undulating curved surface, according to the lever principle, when the flow regulating plate 61 reciprocates, its bottom edge will make arc-shaped equidistant motion along the roller surface, ensuring the closure of the material cavity between the rollers and the density of the incoming material, thereby ensuring the stability of the extruded material bed. The new structural form effectively prevents the overflow of materials, reduces the wear of the roller surface due to the sliding erosion of materials, improves the one-time extrusion effect of the roller press, reduces the circulating load of the roller press system, thereby reducing the reactive loss of the elevator and the roller press, and achieves the control of the flow regulating plate 61 walking along the arc of the roller surface, increases the sealing of the material, and enhances the use effect of the feeding device.

[0051] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope of the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
