Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyor systems, specifically relating to an anti-clogging belt feed inlet. Background Technology

[0002] Belt conveyor systems are the most widely used continuous conveying equipment in industrial production. They mainly consist of a drive unit, idler rollers, and a conveyor belt. The conveyor belt itself is made of rubber (RMA abrasion layer), PVC, PU, ​​or steel cord (ST type). Surface treatments for the conveyor belt include patterns, sidewalls, and guide strips (used as a material inlet).

[0003] A belt conveyor is disclosed in the utility model patent with patent authorization announcement number CN216806924U, which includes a support frame. Both sides of one end of the top outer wall of the support frame are provided with grooves, and a slider is slidably connected inside the groove. A tension roller seat is welded on the top outer wall of the slider, and a driven roller is movably connected to the axis of the outer wall of the adjacent side of the tension roller seat through a bearing. An adjusting rod is welded to one end of the slider, and a positioning post is welded on the inner wall of the support frame adjacent to the driven roller.

[0004] However, the existing belt feed inlets used in belt conveyors also have certain defects. When guiding and conveying materials, the existing belt feed inlets are prone to blockage due to the characteristics and humidity of the materials, resulting in poor material conveying. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-clogging belt feed inlet, which solves the problem that existing belt feed inlets are prone to clogging due to the characteristics and humidity of the materials, resulting in poor material conveying.

[0006] To achieve the above objectives, this utility model provides an anti-clogging belt feed inlet, including a support frame. Two evenly distributed support plates are fixedly connected to the upper end of the support frame. A driven roller is provided on the left side of each support plate, and a driving roller is provided on the right side of each support plate. A conveyor belt is provided on the surface of both the driven and driving rollers. A servo motor is fixedly installed on the right side of the front support plate. The output shaft of the servo motor is rotatably connected to the front support plate and welded to the driving roller. A mounting plate is in contact with the upper left side of each support plate. A feed guide plate is fixedly connected to the other end of the mounting plate and contacts the conveyor belt. A vibrating mechanism is provided at the upper end of each support plate. Non-standard bolts are movably connected to the inner wall of the mounting plate, and these non-standard bolts are threadedly connected to the support plate.

[0007] The principle of this utility model is as follows: by pushing the mounting plate into contact with the support plate, the feed guide plate comes into contact with the conveyor belt and the contact head, and pushes the non-standard bolt through the mounting plate, so that the non-standard bolt drives the end into the support plate. By rotating the non-standard bolt, the non-standard bolt can be installed under the threaded connection, thereby fixing the mounting plate and making the feed guide plate stable.

[0008] When the non-standard bolt rotates and moves downward, it can drive the end head to rotate and move downward. When the end head contacts the limiting rod, the squeezing action of the end head can push the limiting rod to move, thereby driving the end plate to move. This causes the spring to deform, eventually making the limiting rod contact the surface of the non-standard bolt. Under the action of force, the limiting rod slides along the surface of the non-standard bolt. When the limiting rod contacts the limiting groove, the spring returns to its original deformation, pulling the limiting rod to insert into the limiting groove, thus limiting the insertion of the non-standard bolt and avoiding the problem of vibration and desiccation of the non-standard bolt, thereby ensuring the long-term stability of the feed guide plate.

[0009] By applying a pulsed current to the electromagnet, the magnetic attraction direction of the electromagnet can be intermittently changed. When the electromagnet magnetically attracts the magnetic disk, the magnetic disk drives the telescopic rod to slide along the inner wall of the fixed frame, thereby driving the guide block to slide along the inner wall of the fixed frame. This keeps the telescopic rod in a stable position and drives the connecting plate to move, causing the second spring to deform. Ultimately, this causes the contact head to detach from the feed guide plate. When the electromagnet no longer magnetically attracts the magnetic disk, the second spring returns to its original deformation, pushing the connecting plate to drive the telescopic rod to reset. This causes the contact head to contact and impact the feed guide plate, vibrating and oscillating the feed guide plate to prevent material blockage.

[0010] The beneficial effects of this utility model are as follows: This solution uses non-standard bolts to lock the mounting plate and support plate together, and to fix the feed guide plate. With the cooperation of limiting rods, limiting grooves and other structures, the non-standard bolts can be inserted and limited, avoiding the problems of vibration deflection and delamination of non-standard bolts, thus ensuring the long-term stability of the feed guide plate. By applying pulse current to the electromagnet, the magnetic attraction direction of the electromagnet can be changed intermittently, thereby intermittently attracting the magnetic disk. Combined with the deformation of the second spring, the telescopic rod can drive the contact head to continuously contact and impact with the feed guide plate, vibrating and oscillating the feed guide plate, thus avoiding the problem of material blockage at the belt feed inlet.

[0011] Furthermore, the lower end of the non-standard bolt is fixedly connected to an end head, which contacts the support plate. The end head allows the limiting rod to be pressed.

[0012] Furthermore, a limiting groove is formed on the surface of the non-standard bolt, and a limiting rod is slidably connected to the inner wall of the support plate. The limiting rod is slidably connected to the limiting groove, and an end plate is fixedly connected to the end face of the limiting rod away from the limiting groove. The end plate is in contact with the support plate, and a spring is welded to the other end of the end plate. The other end of the spring is welded to the support plate. Through the action of the end plate, spring, and other structures, a good insertion effect of the limiting rod can be ensured.

[0013] Furthermore, multiple limiting grooves are provided, and these multiple limiting grooves are arranged in a circular array on the non-standard bolt. The setting of the limiting grooves facilitates the insertion and use with the limiting rod.

[0014] Furthermore, the vibration mechanism includes a fixed frame, with the upper end of the support plate fixedly connected to the fixed frame. A telescopic rod is slidably connected to the inner wall of the fixed frame. A contact head is fixedly connected to the end face of the telescopic rod near the feed guide plate, and the contact head contacts the feed guide plate. A connecting plate is fixedly sleeved on the outer side of the telescopic rod. A second spring is welded to the end face of the connecting plate near the fixed frame, and the other end of the second spring is welded to the fixed frame. A magnetic disk is fixedly connected to the end face of the telescopic rod near the fixed frame. An electromagnet is fixedly installed on the inner side wall of the fixed frame. Through the combined use of the electromagnet, magnetic disk, and second spring, the contact head can continuously contact and impact the feed guide plate, vibrating the feed guide plate and preventing material blockage.

[0015] Furthermore, a guide block is fixedly connected to the upper side of the telescopic rod, and the guide block is slidably connected to the fixed frame. The telescopic rod can be moved and guided by the guide block.

[0016] Furthermore, the contact surface between the contact head and the feed guide plate is rounded, and the contact head is made of rubber. The use of rubber material gives the contact head good durability. Attached Figure Description

Detailed Implementation

[0024] The implementation examples are basically as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, this embodiment provides an anti-clogging belt feed inlet, including a support frame 1. Two evenly distributed support plates 2 are fixedly connected to the upper end of the support frame 1. A driven roller 3 is provided on the left side of the two support plates 2, and a driving roller 4 is provided on the right side of the two support plates 2. A conveyor belt 5 is provided on the surface of the driving roller 4 and the driven roller 3. A servo motor 6 is fixedly installed on the right side of the front support plate 2. The output shaft of the servo motor 6 is rotatably connected to the front support plate 2. The output shaft of the servo motor 6 is welded to the driving roller 4. A mounting plate 7 is in contact with the upper left side of each support plate 2. A feed guide plate 8 is fixedly connected to the other end of the mounting plate 7. The feed guide plate 8 is in contact with the conveyor belt 5. A non-standard bolt 9 is movably connected to the inner wall of the mounting plate 7. The non-standard bolt 9 is threadedly connected to the support plate 2.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the lower end of the non-standard bolt 9 is fixedly connected to an end head 10, which contacts the support plate 2. The end head 10 allows for the compression of the limiting rod 12. The surface of the non-standard bolt 9 has a limiting groove 11, and multiple limiting grooves 11 are arranged in a circular array on the non-standard bolt 9. The limiting grooves 11 facilitate the insertion of the limiting rod 12. The inner wall of the support plate 2 is slidably connected to the limiting rod 12, and the limiting rod 12 is slidably connected to the limiting groove 11. An end plate 13 is fixedly connected to the end face of the limiting rod 12 away from the limiting groove 11, and the end plate 13 contacts the support plate 2. A spring 14 is welded to the other end of the end plate 13, and the other end of the spring 14 is welded to the support plate 2. Through the action of the end plate 13, spring 14, and other structures, a good insertion effect of the limiting rod 12 can be ensured.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a vibrating mechanism 15 is provided at the upper end of the support plate 2. The vibrating mechanism 15 includes a fixed frame 150. The fixed frame 150 is fixedly connected to the upper end of the support plate 2. A telescopic rod 151 is slidably connected to the inner wall of the fixed frame 150. A contact head 153 is fixedly connected to the end face of the telescopic rod 151 near the feed guide plate 8. The contact head 153 contacts the feed guide plate 8. A connecting plate 154 is fixedly sleeved on the outer side of the telescopic rod 151. The end face of the connecting plate 154 near the fixed frame 150 is... A second spring 155 is welded to one end of the telescopic rod 151, and the other end of the second spring 155 is welded to the fixed frame 150. A magnetic disk 156 is fixedly connected to the end face of the telescopic rod 151 near the fixed frame 150. An electromagnet 157 is fixedly installed on the inner wall of the fixed frame 150. Through the coordinated use of the electromagnet 157, the magnetic disk 156, the second spring 155 and other structures, the contact head 153 can continuously contact and impact the feed guide plate 8 to vibrate the feed guide plate 8 and avoid the problem of material blockage.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a guide block 152 is fixedly connected to the upper side of the telescopic rod 151. The guide block 152 is slidably connected to the fixed frame 150. The telescopic rod 151 can be moved and guided by the guide block 152. The contact surface between the contact head 153 and the feed guide plate 8 is rounded. The contact head 153 is made of rubber. The rubber material makes the contact head 153 have good durability.

[0028] The specific implementation process of this utility model is as follows: By pushing the mounting plate 7 into contact with the support plate 2, the feed guide plate 8 comes into contact with the conveyor belt 5 and the contact head 153, and the non-standard bolt 9 is pushed through the mounting plate 7, so that the non-standard bolt 9 drives the end 10 to be inserted into the support plate 2. By rotating the non-standard bolt 9, the non-standard bolt 9 can be installed under the threaded connection, thereby fixing the mounting plate 7 and making the feed guide plate 8 stable.

[0029] When the non-standard bolt 9 rotates and moves downward, it can drive the end 10 to rotate and move downward. When the end 10 contacts the limiting rod 12, under the squeezing action of the end 10, it can push the limiting rod 12 to move, thereby driving the end plate 13 to move, causing the spring 14 to deform, and finally causing the limiting rod 12 to contact the surface of the non-standard bolt 9. Under the action of force, the limiting rod 12 slides along the surface of the non-standard bolt 9. When the limiting rod 12 contacts the limiting groove 11, the spring 14 returns to its deformation, thereby pulling the limiting rod 12 to insert into the limiting groove 11, and limiting the insertion of the non-standard bolt 9 to avoid the problem of vibration and desiccation of the non-standard bolt 9, so as to ensure the long-term stability of the feed guide plate 8.

[0030] By applying a pulsed current to the electromagnet 157, the magnetic attraction direction of the electromagnet 157 can be intermittently changed. When the electromagnet 157 magnetically attracts the magnetic disk 156, the magnetic disk 156 drives the telescopic rod 151 to slide along the inner wall of the fixed frame 150, thereby driving the guide block 152 to slide along the inner wall of the fixed frame 150. This makes the telescopic rod 151 move stably and drives the connecting plate 154 to move, causing the second spring 155 to deform. Finally, the contact head 153 disengages from the feed guide plate 8. When the electromagnet 157 no longer magnetically attracts the magnetic disk 156, the second spring 155 returns to its original deformation, pushing the connecting plate 154 to drive the telescopic rod 151 to reset and move. This causes the contact head 153 to contact and impact the feed guide plate 8, vibrating and oscillating the feed guide plate 8 to avoid material blockage.

[0031] This solution uses non-standard bolts 9 to lock the mounting plate 7 and support plate 2 together, and to fix the feed guide plate 8 in place. With the cooperation of limiting rod 12, limiting groove 11 and other structures, the non-standard bolts 9 can be inserted and limited to avoid vibration, deflection and unraveling, thus ensuring the long-term stability of the feed guide plate 8. By applying pulse current to electromagnet 157, the magnetic attraction direction of electromagnet 157 can be changed intermittently, thereby intermittently attracting magnetic disk 156. With the deformation of spring 155, the telescopic rod 151 drives the contact head 153 to continuously contact and impact the feed guide plate 8, vibrating and oscillating the feed guide plate 8 to avoid material blockage at the belt feed inlet.
