Description

Technical Field

[0001] The present application relates to the technical field of raw material conveying equipment, and in particular to a material discharge docking mechanism and a material feeding device. Background Art

[0002] The glass preparation process mainly involves raw materials such as high-temperature fused quartz sand and broken glass. In production, the raw materials are continuously supplied to the furnace through a screw feeder according to the process requirements. In this process, parameters such as feeding amount, feeding speed, and raw material uniformity are closely related to the quality of the glass. Therefore, the raw materials need to be mixed evenly in the mixer in advance, then loaded into the transfer tank, and then transferred to the feeding platform to meet the stable process production requirements.

[0003] A Chinese patent with publication number CN215625240U discloses a drug powder transport device for raw material barrels, including: a raw material tank, a material guide device including a docking tube and a conical tube, the conical tube is a cone with a diameter gradually increasing from top to bottom, which is convenient for the drug powder to be transported to other containers, aggregates the flow direction of the drug powder, prevents powder from being blown, and is also convenient for docking with the container. A feed barrel is installed on the top of the container, and a docking cone with an inner diameter gradually increasing from bottom to top is provided at the upper end of the feed barrel, an O-ring is installed on the upper end surface of the docking cone, and an outward outer flange is provided around the middle outer wall of the cone, and the outer flange presses the O-ring tightly, thereby realizing a sealed connection between the cone tube and the docking cone.

[0004] The sealing and stability of the docking mechanism between the mixer and the transfer tank are crucial. However, in actual production, the transfer tank is usually placed on a pallet and transported by an electric ground bull. Due to the differences in the sizes of the transfer pallet and the transfer tank, as well as the flatness of the ground and the flatness of the equipment placement, the sealing will be affected, making it prone to faults such as poor sealing, jamming, and tilting.

In the non-connected state, the compression spring connection assembly pushes the double-sided butt flanges away from the lifting flange; in the connected state, the double-sided butt flanges squeeze the compression spring connection assembly and abut against the lifting flange.

[0013] In some embodiments, sealing bodies are respectively provided on the two side surfaces of the double-sided docking flange that abut against the lifting flange and the transfer tank.

[0014] In some embodiments, the compression spring coupling assembly includes:

[0015] The base is fixed to the side of the lifting flange facing away from the double-sided docking flanges;

[0016] A slide rod, which passes through the lifting flange and is fixedly connected to the butt flanges on both sides, and the slide rod is suitable for sliding relative to the lifting flange;

[0017] The sleeve is sleeved on the outer peripheral side of the slide rod and fixedly connected with the base. The slide rod is suitable for sliding relative to the sleeve.

[0018] In some embodiments, the compression spring connection assembly further comprises:

[0019] The spring is connected between the sleeve and the slide rod. When the double-sided butt flanges move toward the lifting flange, the slide rod slides relative to the sleeve and drives the spring to be in a compressed state.

[0020] In some embodiments, the compression spring connection assembly further comprises:

[0021] The proximity switch is arranged on the base and is arranged away from the flange of the lifting part; when the sleeve moves to trigger the proximity switch, the lifting unit stops moving.

[0022] In some embodiments, a limiting sliding groove is provided on the side wall of the sleeve, and the extending direction of the limiting sliding groove is the same as the extending direction of the sliding rod;

[0023] The slide bar is fixed with a fixing pin, which at least partially extends into the limiting slide groove, and the fixing pin abuts against the limiting slide groove to limit the displacement limit of the double-sided docking flanges relative to the lifting part flange.

[0024] In some embodiments, an outer peripheral side of the sleeve is provided with an external thread, and the base is correspondingly provided with an internal thread, and the sleeve is threadedly connected to the base.

[0025] In some embodiments, the discharge docking mechanism further comprises:

[0026] The universal floating joint is connected between the lifting unit and the lifting flange. The universal floating joint rotates with the telescopic rod of the lifting unit to adjust the angle between the telescopic rod and the plane where the lifting flange is located.

[0027] In some embodiments, there are multiple lifting units, which are arranged around the outer peripheral side of the connecting flange and are evenly distributed; there are multiple compression spring connecting assemblies, which are arranged around the circumferential surface of the lifting part flange and are evenly distributed.

[0028] In a second aspect, the present application further provides a feeding device, comprising: a mixer, which is arranged on a supporting platform, and a discharge port is arranged at the bottom of the mixer;

[0029] And the discharge docking mechanism as mentioned above; the connecting flange of the discharge docking mechanism is fixedly connected to the discharge port.

[0030] Through the above technical solution, the material discharging and docking mechanism provided by the present application has the following beneficial effects:

[0031] 1. The discharge docking mechanism provided in the embodiment of the present application is arranged between the discharge port and the transfer tank, and the discharge docking mechanism is provided with a soft connection part between the connecting pipe flange and the lifting part flange, and further connects the lifting part flange and the transfer tank at the same time through the double-sided docking flange, so that the double-sided docking flange is used as a movable part. Even if the surface of the feed port of the transfer tank is tilted, the adaptive adjustment of the mating surface can be achieved to ensure the sealing effect. Reduce the dust overflow during discharge caused by different sizes of transfer tanks, loose cooperation with cooperating equipment, mechanical failures, etc., reduce the failure rate during cooperation such as mechanical jamming, improve the sealing effect when cooperating with the transfer tank, avoid dust overflow, ensure the docking seal with the transfer tank, and ensure the reliability of subsequent processes and production.

[0032] 2. When the surface of the feed port of the transfer tank is tilted, the double-sided docking flange will also tilt after docking with the transfer tank. The relatively high side of the double-sided docking flange in the height direction will first trigger the proximity switch of the compression spring connection assembly at the corresponding position, causing the lifting unit on the relatively high side to stop moving to avoid excessive extrusion. The lifting unit on the relatively low side will continue to move, so that the double-sided docking flange on the relatively low side will be tightly pressed against the surface of the feed port of the transfer tank, which will trigger the proximity switch of the compression spring connection assembly at the corresponding position, causing the lifting unit on the relatively low side to stop moving, thereby meeting the tight contact requirements of various areas around the feed port of the transfer tank and avoiding excessive extrusion in local areas. This reduces the impact of size differences and production environment factors on the sealing effect of the equipment, avoids dust spillage and leakage, reduces waste of raw materials and environmental pollution, avoids equipment jamming or failure to be in place, reduces equipment failure rate, increases equipment service life and reduces operating costs.

[0033] 3. When the inlet surface of the transfer tank is tilted, the proximity switches of the compression spring connection assembly are triggered in sequence, so the time for each lifting unit to stop moving is different, resulting in different telescopic lengths of each lifting unit. By setting a universal floating joint, the loose sealing caused by the tilt of the lifting flange can be compensated. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Combine the following Figures 1 to 4 , describing an embodiment of the present application.

[0049] According to an embodiment of the present application, on the one hand, a discharge docking mechanism is provided, which is arranged between the discharge port 3 and the transfer tank 5, and the discharge docking mechanism includes:

[0050] The connecting flange 4 is connected with the discharge port 3;

[0051] The lifting flange 8 is spaced apart from the connecting flange 4;

[0052] The soft connection part 19 is made of a soft material and is conductively connected between the pipe flange 4 and the lifting flange 8;

[0053] The lifting unit 6 is fixed on the pipe flange 4, and the lifting unit 6 drives the lifting flange 8 to move in a direction close to or away from the pipe flange 4;

[0054] The double-sided butt flange 10 is arranged on the side of the lifting flange 8 away from the connecting flange 4. The double-sided butt flange 10 has a non-connected state where it is spaced apart from the lifting flange 8 and the transfer tank 5, and a connected state where it is abutted against the lifting flange 8 and the transfer tank 5.

[0055] The compression spring connection assembly 7 connects the double-sided butt flange 10 with the lifting flange 8. In the non-connected state, the compression spring connection assembly 7 pushes the double-sided butt flange 10 away from the lifting flange 8; in the connected state, the double-sided butt flange 10 squeezes the compression spring connection assembly 7 and abuts against the lifting flange 8.

[0056] The discharge docking mechanism is arranged between the discharge port 3 and the transfer tank 5, wherein the discharge port 3 can be the discharge port of the mixer 2, and the transfer tank 5 can be movably arranged relatively below the discharge port 3. When discharge is required, the discharge port 3 and the transfer tank 5 are connected through the discharge docking mechanism so as to transfer the material in the mixer 2 to the transfer tank 5.

[0057] In actual production, the transfer tank is usually placed on a pallet and transported by an electric ground bull. Due to the differences in the sizes of the transfer pallet and the transfer tank, as well as factors such as the flatness of the ground and the flatness of the equipment placement, the surface of the feed port of the transfer tank 5 may not be completely parallel to the lower surface of the discharge port 3. The inclination of the feed port surface of the transfer tank 5 will affect the sealing of the connection. Faults such as poor sealing, jamming, and tilting are prone to occur. The discharge docking mechanism provided in the embodiment of the present application is arranged between the discharge port 3 and the transfer tank 5, and the discharge docking mechanism is provided by providing a soft connection portion 19 between the connecting flange 4 and the lifting portion flange 8, and further connecting the lifting portion flange 8 and the transfer tank 5 at the same time through the double-sided docking flange 10, so that the double-sided docking flange 10 serves as a movable part. Even if the feed port surface of the transfer tank 5 is tilted, adaptive adjustment of the mating surface can be achieved to ensure the sealing effect. Reduce the dust overflow during discharge due to different transfer tank sizes, loose coordination with cooperating equipment, mechanical failures, etc., reduce the failure rate such as mechanical jamming, improve the sealing effect when cooperating with the transfer tank, avoid dust overflow, ensure the docking seal with the transfer tank, and ensure the reliability of subsequent processes and production.

[0058] The pipe flange 4 is a long-neck flange, which is used to connect the discharge port 3 of the mixer. The lifting flange 8 is arranged relatively below the pipe flange 4, and the lifting flange 8 is connected to the pipe flange 4 through a plurality of lifting units 6. The lifting flange 8 rises to leave room for the transfer tank 5. At the same time, since the pipe flange 4 and the lifting flange 8 are connected through the soft connection part 19, flexible deformation can be achieved. When the surface of the inlet of the transfer tank 5 is tilted, they can still fit smoothly, realizing adaptive adjustment of the fitting surface, avoiding the loose fitting and easy jamming caused by rigid connection.

[0059] A double-sided docking flange 10 is also provided on the side of the lifting flange 8 away from the connecting flange 4. The lifting flange 8 is connected to the double-sided docking flange 10 through a compression spring connecting assembly 7. A proximity switch 11 is provided on the compression spring connecting assembly 7, which can trigger the lifting unit 6 to stop moving according to the moving distance of the double-sided docking flange 10.

[0060] In this embodiment, there are multiple lifting units 6 and multiple compression spring connection assemblies 7.

[0061] The double-sided butt flange 10 has a non-connected state in which it is spaced from both the lifting flange 8 and the transfer tank 5, and a connected state in which it is in contact with both the lifting flange 8 and the transfer tank 5. When switching from the non-connected state to the connected state, the first side surface of the double-sided butt flange 10 first contacts the surface of the inlet of the transfer tank 5, and compresses the compression spring connection assembly 7, so that the second side surface of the double-sided butt flange 10 contacts the lifting flange 8, thereby enabling the double-sided butt flange 10 to be connected between the lifting flange 8 and the transfer tank 5.

[0062] When the surface of the feed port of the transfer tank 5 is tilted, the double-sided docking flange 10 will also tilt after docking with the transfer tank 5. The relatively high side of the double-sided docking flange 10 along the height direction will first trigger the proximity switch 11 of the compression spring connection assembly 7 at the corresponding position, so that the lifting unit 6 on the relatively high side stops moving to avoid excessive extrusion. The lifting unit 6 on the relatively low side will continue to move, so that after the double-sided docking flange 10 on the relatively low side is pressed against the surface of the feed port of the transfer tank 5, the proximity switch 11 of the compression spring connection assembly 7 at the corresponding position will be triggered, so that the lifting unit 6 on the relatively low side stops moving, thereby meeting the pressing requirements of various areas around the feed port of the transfer tank 5, while avoiding excessive extrusion in local areas. Thereby reducing the impact of the size differences of the supporting equipment and production environment factors on the sealing effect of the equipment, avoiding dust spillage and leakage, reducing the waste of raw materials and environmental pollution, avoiding equipment jamming or failure to be in place, reducing equipment failure rate, increasing equipment service life and reducing operating costs.

[0063] In some embodiments, in combination Figure 2 As shown, sealing bodies 9 are respectively provided on the two side surfaces of the double-sided docking flange 10 that abut against the lifting flange 8 and the transfer tank 5 .

[0064] The upper and lower surfaces of the double-sided butt flange 10 are fixed with a sealing body 9 by bonding. The sealing body can be made of rigid polyurethane foam, which cooperates with the double-sided butt flange 10 to form a rigid-flexible sealing condition, making the equipment sealing effect more outstanding.

[0065] In some embodiments, in combination Figure 3 , Figure 4 As shown, the compression spring connection assembly 7 includes:

[0066] The base 15 is fixed to the side of the lifting flange 8 away from the double-sided docking flange 10;

[0067] A slide bar 12 passes through the lifting flange 8 and is fixedly connected to the double-sided docking flanges 10. The slide bar 12 is suitable for sliding relative to the lifting flange 8.

[0068] The sleeve 13 is sleeved on the outer peripheral side of the slide bar 12 and fixedly connected to the base 15 . The slide bar 12 is suitable for sliding relative to the sleeve 13 .

[0069] The base 15 is constructed in an L shape, with the bottom connected to the surface of the lifting flange 8 facing away from the double-sided docking flange 10 . The base 15 also extends toward the surface away from the lifting flange 8 to fix the proximity switch 11 .

[0070] A through hole is formed on the lifting flange 8, and the sliding rod 12 passes through the lifting flange 8 and is fixedly connected to the double-sided docking flanges 10. While satisfying the connection between the lifting flange 8 and the double-sided docking flanges 10, the double-sided docking flanges 10 can move relative to the lifting flange 8.

[0071] In some embodiments, in combination Figure 4 As shown, the compression spring connection assembly 7 also includes:

[0072] The spring 14 is connected between the sleeve 13 and the slide bar 12. When the double-sided docking flange 10 moves toward the lifting flange 8, the slide bar 12 slides relative to the sleeve 13 and drives the spring 14 to be in a compressed state.

[0073] The spring 14 is disposed in the sleeve 13 and sleeved on the outer circumference of the slide rod 12 .

[0074] The spring 14 cooperates with the slide bar 12 to realize the up and down movement and reset of the slide bar 12 .

[0075] When the lifting unit 6 descends, the double-sided butt flange 10 moves toward the lifting flange 8, the slide bar 12 slides relative to the sleeve 13, and drives the spring 14 to be in a compressed state. When the lifting unit 6 rises, the spring 14 pushes the double-sided butt flange 10 to move away from the lifting flange 8, so that the double-sided butt flange 10 is reset.

[0076] In some embodiments, in combination Figure 4 As shown, a limiting sliding groove 131 is provided on the side wall of the sleeve 13, and the extending direction of the limiting sliding groove 131 is the same as the extending direction of the sliding rod 12;

[0077] A fixing pin 16 is fixed to the slide bar 12 . The fixing pin 16 at least partially extends into the limiting slide groove 131 . The fixing pin 16 abuts against the limiting slide groove 131 to limit the displacement limit of the double-sided docking flange 10 relative to the lifting flange 8 .

[0078] The spring 14 pushes the double-sided butt flange 10 to move in a direction away from the lifting portion flange 8 , and reaches the displacement limit when the fixing pin 16 abuts against the limiting sliding groove 131 .

[0079] In addition, the movement of the fixing pin 16 along the path of the limiting sliding groove 131 can ensure the accuracy of the moving path and prevent the sliding rod 12 from rotating or deviating.

[0080] In some embodiments, in combination Figure 4 As shown, the compression spring connection assembly 7 also includes:

[0081] The proximity switch 11 is disposed on the base 15 and is disposed away from the lifting flange 8 ; when the sleeve 13 moves to trigger the proximity switch 11 , the lifting unit 6 stops moving.

[0082] The base 15 is constructed in an L-shape, and the bottom is connected to the surface of the lifting flange 8 on one side away from the double-sided docking flange 10. The base 15 also extends toward the surface away from the lifting flange 8, and is used to fix the proximity switch 11. A long slot hole is provided on the extended portion of the base 15, and the long slot hole is used to install and fix the proximity switch 11. The proximity switch 11 can be flexibly adjusted in the long slot hole to change the telescopic stroke of the lifting unit 6 to meet different work requirements.

[0083] The proximity switch 11 may be an inductive proximity switch, specifically an NPN three-wire inductive switch powered by a 24V power supply, which is used to transmit a switch signal to the control system so that the staff can know whether the equipment is operating normally, thereby improving the equipment's adaptability and monitoring capabilities, reducing human intervention, improving the level of automation, and reducing equipment failure rates.

[0084] The lifting unit 6 can be specifically a cylinder or a linear motor. The lifting unit 6 executes the on-off command of the PLC main control program to drive the lifting flange 8 to reciprocate up and down.

[0085] The slide bar 12 cooperates with the proximity switch 11. When the slide bar 12 reaches the sensing area of ​​the proximity switch 11, the proximity switch 11 is turned on, and the operating status signal of the lifting unit 6 is fed back to the control system.

[0086] In some embodiments, an outer peripheral side of the sleeve 13 is provided with an external thread, and the base 15 is correspondingly provided with an internal thread, and the sleeve 13 is threadedly connected to the base 15 .

[0087] The sleeve 13 is threadedly connected to the base 15 , so that the sleeve 13 can be rotated up and down according to the use requirements, thereby driving the slide rod 12 to move axially, which can expand the working range of the proximity switch 11 .

[0088] In some embodiments, in combination Figure 3As shown, the material discharging and docking mechanism also includes:

[0089] The universal floating joint 17 is connected between the lifting unit 6 and the lifting flange 8. The universal floating joint 17 rotates along with the telescopic rod of the lifting unit 6 to adjust the angle between the telescopic rod and the plane where the lifting flange 8 is located.

[0090] The discharge docking mechanism further includes a connection base 18 , which is fastened to the lifting flange 8 by bolts, and the universal floating joint 17 is connected to the lifting flange 8 via the connection base 18 .

[0091] The universal floating joint 17 is connected to the telescopic rod of the lifting unit 6, and the universal floating joint 17 can be freely adjusted at multiple angles.

[0092] When the inlet surface of the transfer tank 5 is tilted, the proximity switches 11 of the compression spring connection assembly 7 are triggered in sequence, so that the time for each lifting unit 6 to stop moving is different, resulting in different telescopic lengths of each lifting unit 6. By providing a universal floating joint 17, the loose sealing caused by the tilt of the lifting flange 8 can be compensated.

[0093] In some embodiments, in combination Figure 2 As shown, there are multiple lifting units 6, which are arranged around the outer peripheral side of the connecting flange 4 and are evenly distributed; there are multiple compression spring connection assemblies 7, which are arranged around the circumferential surface of the lifting part flange 8 and are evenly distributed.
