Description

Technical Field

[0001] The present application relates to the technical field of material distribution, and in particular to an electric three-way distributor for preventing material leakage. Background Art

[0002] A three-way distributor is a device used to change the flow direction of materials and transfer materials. Usually, it transfers the upstream single-line material flow to the downstream double-line material flow. However, when the traditional three-way distributor distributes materials, most of them rely on the reciprocating swing of a flat swing plate arranged in the distributor housing. Due to the excessive gaps between various components, especially the non-closed gap between the flat swing plate and the housing, material leakage and diversion will occur. If different materials are mixed together, it will become unqualified variegated materials, resulting in a decline in product quality. Content of the Utility Model

[0003] The utility model aims to solve the problem that there is a gap between the flat swing plate and the housing of the above-mentioned three-way distributor, which is likely to cause material leakage, and thus provides a three-way distributor that can avoid material leakage.

[0004] The technical solution adopted by the utility model to solve the above problems is as follows:

[0005] An electric three-way distributor for preventing material leakage includes a three-way housing. An inlet channel and two outlet channels communicating with the inlet channel are arranged in the three-way housing. A trough-shaped flap is rotatably arranged in the area where the inlet channel extends towards the two outlet channels. A driving component is connected to one side of the trough-shaped flap. Flow guiding plates are arranged on the front side and the rear side of the inlet channel perpendicular to the trough-shaped flap. The upper end of the flow guiding plate is fixed to the three-way housing, and a gap is provided between the lower end of the flow guiding plate and the three-way housing. When the driving component drives the trough-shaped flap to rotate, the trough-shaped flap closes one of the outlet channels, and the trough edge of the trough-shaped flap is inserted into the gap between the flow guiding plate and the three-way housing.

[0006] The utility model adopting the above technical solution, compared with the prior art, has the following beneficial effects:

[0007] Through the three-way distributor of the utility model, material leakage can be effectively avoided. The utility model changes the flat swing plate of the traditional distributor to a trough-shaped flap, rotatably arranges the trough-shaped flap in the area where the inlet channel extends towards the two outlet channels, and arranges flow guiding plates on the front side and the rear side of the inlet channel. By controlling the rotation of the trough-shaped flap to close one of the outlet channels, when it is closed, the two trough edges of the trough-shaped flap are inserted into the gap between the flow guiding plate and the three-way housing, and a closed material transportation channel is formed between the flow guiding plate and the trough-shaped flap and the other outlet channel. At this time, the gap between the trough-shaped flap and the flow guiding plate is completely closed, thus preventing the material entering the inlet channel from leaking through the gap between the trough-shaped flap and the flow guiding plate into the closed outlet channel.

[0008] Preferably, a further technical solution of the utility model is as follows:

[0009] The lower end of the deflector is arranged as an inverted triangle, and the two hypotenuses at the lower end of the deflector are respectively parallel to the discharging directions of the two discharging channels. With the above structure, when the trough-shaped flap closes one of the discharging channels, the bottom plate of the trough-shaped flap abuts against the hypotenuse of the deflector, further enhancing the anti-leakage effect.

[0010] The driving assembly includes a rotating shaft and a linear actuator arranged outside the tee-shaped housing. The inner end of the rotating shaft is fixed to one side of the trough-shaped flap, and the outer end of the rotating shaft passes through the tee-shaped housing and is rotatably connected to the piston rod of the linear actuator. When the piston rod expands and contracts, the trough-shaped flap is driven to rotate by the rotating shaft. The piston rod of the linear actuator drives the rotating shaft to rotate, thereby driving the trough-shaped flap to rotate.

[0011] A limiting block is connected to the other side of the trough-shaped flap, and travel switches are arranged on both sides of the limiting block. When the trough-shaped flap drives the limiting block to rotate and touches one of the travel switches, the travel switch sends a control signal to control the linear actuator to stop running. By adding the limiting block and the travel switch, after the trough-shaped flap flips to close one of the discharging channels, the limiting block touches one of the travel switches, and through the control signal of the travel switch, the linear actuator is automatically controlled to stop driving the trough-shaped flap to rotate.

[0012] The front end of the piston rod of the linear actuator is pin-connected with a swing arm, and the other end of the swing arm is fixedly sleeved on the rotating shaft. When the piston rod of the linear actuator expands and contracts, the rotating shaft is driven to rotate by the swing arm.

[0013] A support frame is fixed outside the tee-shaped housing, and the linear actuator is pin-connected to the support frame. With the above structure, it is convenient for the linear actuator to swing according to the running track of the swing arm, making the driving process smoother.

[0014] A number of round steel bars are equidistantly arranged on the deflector. By adding multiple round steel bars, the surface of the deflector is wavy, reducing the direct contact between the material and the deflector, thereby reducing the wear of the deflector.

[0015] Limit baffles are arranged on the left and right sides of the upper part of the feeding channel. When the trough edge of the trough-shaped flap is inserted into the gap between the deflector and the tee-shaped housing, the trough-shaped flap abuts against the outer wall of the limit baffle. By the abutment of the limit baffle and the trough-shaped flap, the feeding channel is completely separated from the closed discharging channel, preventing the material from leaking from the upper end of the trough-shaped flap.

Detailed implementation manners

[0023] The following further illustrates the present utility model in conjunction with embodiments, and the purpose is only to better understand the content of the present utility model. Therefore, the examples given do not limit the protection scope of the present utility model.

[0024] Refer to Figure 1-6, an embodiment of the present application discloses an anti-leakage electric three-way feeder, which includes a three-way housing 1. A feed channel and a left discharge channel and a right discharge channel communicating with the feed channel are provided in the three-way housing 1. A trough-shaped flap 18 is rotatably provided at the lower end of the area where the feed channel extends towards the two discharge channels. The trough edges 183 on both sides of the trough-shaped flap 18 are perpendicular to the bottom plate 181 of the trough-shaped flap 18. The two trough edges 183 have the same size specification. Preferably, the bottom plate 181 and the trough edges 183 of the trough-shaped flap 18 are made of 5 mm thick stainless steel plate to increase the wear resistance of the trough-shaped flap 18. A 10 mm thick high molecular polyethylene wear-resistant plate 182 is fixedly laid on the bottom plate 181 of the trough-shaped flap 18, which can effectively reduce the wear of the bottom plate 181. The height of the trough edge 183 gradually decreases from the middle to both ends. One side of the trough-shaped flap 18 is connected with a driving component, and the trough-shaped flap 18 is driven to flip by the driving component. Flow guide plates 15 are provided on the front and rear inner walls of the feed channel perpendicular to the trough-shaped flap 18. The upper end of the flow guide plate 15 is provided with a first convex edge 151 protruding outwards. The first convex edge 151 is fixed to the three-way housing 1 by bolts. A gap is provided between the lower end of the flow guide plate 15 and the three-way housing 1, and the depth of the gap is greater than the thickness of the trough edge 183. When the driving component drives the trough-shaped flap 18 to flip, the trough-shaped flap 18 closes one of the discharge channels, and the two trough edges 183 of the trough-shaped flap 18 are respectively inserted into the gaps between the adjacent flow guide plates 15 and the three-way housing 1.

[0025] In this embodiment, the lower end of the flow guide plate 15 is provided as an inverted triangle. The left hypotenuses of the two flow guide plates 15 are parallel to the discharge direction of the right discharge channel, and the right hypotenuses of the two flow guide plates 15 are parallel to the discharge direction of the left discharge channel. A turntable 17 is fixed by bolts in the middle of the two trough edges 183 of the trough-shaped flap 18. The hypotenuse of the flow guide plate 15 is tangent to the turntable 17. Through the above structure, when the trough-shaped flap 18 closes one of the discharge channels, the bottom plate 181 of the trough-shaped flap 18 abuts against the hypotenuse of the flow guide plate 15, further increasing the anti-leakage effect.

[0026] In this embodiment, the driving assembly includes a first rotating shaft 11 and a linear driver 3. The linear driver 3 is an electric push rod. A support frame 2 is fixed to the outer right side of the tee-shaped housing 1. Preferably, the support frame 2 is made of an I-beam. A right-angle area is cut off from the inner end of the I-beam, and the right-angle side of the I-beam is welded to the outer wall on the upper right side and the front outer wall of the tee-shaped housing 1. A reinforcing rib 22 is also welded between the top surface of the I-beam and the tee-shaped housing 1 to increase the stability of the support frame 2. A downward first clamping plate 21 is bolted to the bottom of the front end of the I-beam. The housing of the linear driver 3 is pinned in the first clamping plate 21. The front end of the piston rod of the linear driver 3 is fixed with a second clamping plate 31. A swing arm 32 is pinned in the second clamping plate 31. The other end of the swing arm 32 is fixedly sleeved on the outer end of the first rotating shaft 11. A first guide cylinder 12 is fixed to the front outer wall of the tee-shaped housing. The first guide cylinder 12 is sleeved on the first rotating shaft 11, enabling the first rotating shaft 11 to rotate in the first guide cylinder 12. The inner end of the first rotating shaft 11 passes through the first guide cylinder 12 and the tee-shaped housing 1 and is coaxially fixed to the front turntable 17. When it is necessary to close the left discharge channel, the piston rod is controlled to retract, and the trough-shaped flap 18 is driven to flip through the swing arm 32 and the first rotating shaft 11 to close the left discharge channel. When it is necessary to close the right discharge channel, the piston rod is controlled to extend, and the trough-shaped flap 18 is driven to flip through the swing arm 32 and the first rotating shaft 11 to close the right discharge channel. Since the lower end of the swing arm 32 needs to rotate along the axis of the first rotating shaft 11, the pin joint point where the swing arm 32 is pinned to the second clamping plate 31 will displace in the vertical direction. Therefore, the linear driver 3 and the support frame 2 are pinned, so that when the piston rod expands and contracts to drive the swing arm 32 to swing, the linear driver 3 can adaptively adjust according to the running track of the swing arm 32, making the driving process smoother.

[0027] In this embodiment, a second guide cylinder 14 is fixed on the outer wall at the rear side of the tee housing 1. A second rotating shaft 13 is movably inserted into the second guide cylinder 14. The inner end of the second rotating shaft 13 passes through the tee housing 1 and is coaxially fixed to the rear-side turntable 17. A limit block 4 is fixedly sleeved on the outer end of the rotating shaft. The upper side surface of the limit block 4 is set as an inclined surface inclined towards the middle. Travel switches 5 are arranged on the outer walls of the tee housing 1 on both sides of the limit block 4. The left travel switch 5 is used to control the piston rod to stop extending, and the right travel switch 5 is used to control the piston rod to stop retracting. When the trough-shaped flap 18 flips, the limit block 4 is driven to rotate through the turntable 17 and the second rotating shaft 13; when the trough-shaped flap 18 closes the left discharge channel, the right inclined surface of the limit block 4 contacts the roller of the right travel switch 5, and the right travel switch 5 sends a control signal to the linear actuator 3 to control the piston rod to stop retracting; when the trough-shaped flap 18 closes the right discharge channel, the left inclined surface of the limit block 4 contacts the roller of the left travel switch 5, and the left travel switch 5 sends a control signal to the linear actuator 3 to control the piston rod to stop extending. By adding the limit block 4 and the travel switch 5, after the trough-shaped flap 18 flips and closes one of the discharge channels, the limit block 4 contacts one of the travel switches 5, and through the control signal of the travel switch 5, the linear actuator 3 is automatically controlled to stop driving the trough-shaped flap 18 to rotate.

[0028] In this embodiment, a plurality of round steels 152 are equidistantly arranged on the two flow guide plates 15. Each round steel 152 is perpendicular to the feeding direction. By adding a plurality of round steels 152, the surface of the flow guide plate 15 is wavy, reducing the direct contact between the material and the flow guide plate 15, thereby reducing the wear of the flow guide plate 15.

[0029] In this embodiment, limit baffles 16 are arranged on the left and right sides above the feeding channel. Specifically, the upper end of the limit baffle 16 is a second convex edge 161 protruding outwards. The second convex edge 161 is fixed to the tee housing 1 by bolts. A gap is provided between the lower end of the limit baffle 16 and the tee housing 1. When the trough edge 183 of the trough-shaped flap 18 is inserted into the gap between the flow guide plate 15 and the tee housing 1, the trough-shaped flap 18 abuts against the outer wall of the limit baffle 16. By abutting the limit baffle 16 against the trough-shaped flap 18, the feeding channel is completely separated from the closed discharge channel, preventing the material from leaking from the upper end of the trough-shaped flap 18.

[0030] As a preference, the tee housing 1 in this embodiment is made of steel. The steel plates of each surface of the tee housing 1 are processed in advance according to the design dimensions, and then the surfaces are connected by bolts to form the tee housing 1, thereby avoiding the deformation of the tee housing 1 caused by welding and affecting the material conveying efficiency; flanges are welded at the feeding port of the feeding channel and the discharging ports of the two discharging channels, facilitating the connection of other equipment.

[0031] In this embodiment, the planar swing plate of the traditional material distributor is changed to a trough-shaped flap 18, the trough-shaped flap 18 is rotatably arranged in the area where the feeding channel extends to the two discharging channels, and flow guiding plates 15 are arranged on the front side and the rear side of the feeding channel. By controlling the rotation of the trough-shaped flap 18, one of the discharging channels is closed. When it is closed, the two side trough edges 183 of the trough-shaped flap are inserted into the gap between the flow guiding plate 15 and the tee housing 1, and a closed material transportation channel is formed with the other discharging channel through the flow guiding plate 15 and the trough-shaped flap 18. At this time, the gap between the trough-shaped flap 18 and the flow guiding plate 15 is completely closed, thereby preventing the material entering the feeding channel from leaking through the gap between the trough-shaped flap 18 and the flow guiding plate 15 into the closed discharging channel.
