Description

Technical Field

[0001] The utility model relates to the technical field of feeding mechanisms, in particular to an anti-blocking feeding mechanism. Background Art

[0002] The feeding mechanism is a component used in industrial production to automatically or semi-automatically feed materials into processing or packaging equipment. It plays a key role in daily production processes. There are many types of feeding mechanisms on the market, such as step-type feeding channels, flap mechanisms, hopper-type feeding mechanisms, tray feeding mechanisms, vibrating plate feeding mechanisms, and coil feeding mechanisms. These different types of feeding mechanisms are suitable for different products and application scenarios, including but not limited to electronic component assembly lines, food processing, pharmaceuticals, packaging industries, and other occasions that require automated material handling.

[0003] In the prior art, when feeding granular materials, the materials are generally stored in the silo above the equipment, and then the silo is opened to feed the materials; however, when the granular materials are fed downward, the particles are easily accumulated, and material bridging and rat hole blockage occur in the pipeline. It is necessary to knock the pipeline to disperse the accumulated and blocked materials to achieve the purpose of unblocking. How to invent an anti-blocking feeding mechanism to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0011] By adopting the above technical solution, when unloading materials inside the silo, the motor is started to rotate the first gear on the top, and the second gear is cooperated to make the two first gears rotate synchronously, and the eccentric shaft at the upper end rotates synchronously to cooperate with the connecting rod so that the adjusting rod on one side drives the two reciprocating plates on the inner wall of the unloading pipe to reciprocate and extend to prevent material blockage.

[0012] Preferably, one end of the second gear is fixedly connected to a rotating shaft rotatably connected to the inner wall of the fixing seat, one end of the rotating shaft is fixedly connected to a driving wheel groove, and a transmission belt drivingly connected to the transmission wheel groove is installed on the driving wheel groove.

[0013] Preferably, the inner wall of the fixed sleeve is provided with a sliding groove slidably connected to the outer wall of the sleeve rod, the inner wall of the bottom end of the sleeve rod is threadedly connected to the outer wall of the reciprocating screw rod, and the upper end of the sleeve rod is conical.

[0014] Preferably, one end of the reciprocating screw rod is rotatably connected to the inner wall of the fixing frame, and the surface of the fixing frame is provided with a rounded corner.

[0015] By adopting the above technical solution, while the second gear cooperates with the first gear to rotate, the reciprocating screw inside the fixed frame rotates at the same time, causing the outer sleeve rod to slide back and forth up and down, and the internal material is cleared during the sliding process, further preventing the material from being blocked.

[0016] The beneficial effects of the utility model are:

[0017] When unloading the material inside the silo, start the motor to rotate the first gear and the second gear, and the eccentric shaft at the upper end of the first gear rotates one end of the connecting rod to change the position of the adjusting rod on one side, thereby driving the two reciprocating plates of the adjusting rod located on the inner wall of the unloading pipe to reciprocate and extend. At the same time, when the second gear rotates, the transmission wheel groove inside the fixed frame drives the reciprocating screw rod above to rotate at the same time, and the sleeve rod outside the reciprocating screw rod slides up and down on the inner wall of the fixed sleeve. During the sliding process, the upper end dredges the internal material to further prevent the material from being blocked, thereby avoiding the bridging, rat hole and other blockages of the granular material on the inner wall of the unloading pipe when loading.

[0029] A driving chamber 6 is provided inside the fixed frame 5, one end of the driving chamber 6 is fixedly connected to a fixing sleeve 7, a sleeve rod 11 is installed on the inner wall of the fixing sleeve 7, a reciprocating screw rod 9 is installed on the inner wall of the sleeve rod 11, and one end of the reciprocating screw rod 9 is fixedly connected to a transmission wheel groove 10.

[0030] Furthermore; the output end of the motor 4 is fixedly connected to the fixed shaft of one of the first gears 13, the first gear 13 is meshingly connected to the second gear 19, the outer wall of the eccentric shaft 14 is rotatably connected to the inner wall of the connecting rod 15, one end of the adjusting rod 16 is fixedly connected to the limiting shaft 17 rotatably connected to one end of the connecting rod 15, and the outer wall of the adjusting rod 16 is slidably connected to the inner wall of the discharge pipe 2.

[0031] It should be noted that when the material inside the silo 1 is discharged, the motor 4 is started to rotate the first gear 13 at the top, and at the same time, the second gear 19 is meshed and connected to make the two first gears 13 rotate synchronously, and the eccentric shaft 14 at the upper end of the first gear 13 rotates synchronously. While rotating, one end of the connecting rod 15 rotates, and the position of the other end thereof is offset, so that the position of the adjusting rod 16 on one side is changed, driving the two reciprocating plates 21 of the adjusting rod 16 located on the inner wall of the discharge pipe 2 to reciprocate and extend, and collide with the material inside to avoid material blockage.

[0032] Furthermore, one end of the second gear 19 is fixedly connected to a rotating shaft 18 rotatably connected to the inner wall of the fixed seat 3, one end of the rotating shaft 18 is fixedly connected to a driving wheel groove 20, and a transmission belt 12 is installed on the driving wheel groove 20 for transmission connection to the transmission wheel groove 10.

While rotating, one end of the connecting rod 15 rotates, and the position of the other end thereof is offset, so that the position of the adjusting rod 16 on one side is changed, and the two reciprocating plates 21 of the adjusting rod 16 located on the inner wall of the discharge pipe 2 are driven to reciprocate and extend, and collide with the material inside to avoid material blockage. When the second gear 19 rotates, the rotating shaft 18 drives the driving wheel groove 20 at one end to rotate, and cooperates with the transmission belt 12 installed on the driving wheel groove 20, so that the driving wheel groove 10 inside the fixed frame 5 drives the reciprocating screw 9 above to rotate at the same time, and the sleeve rod 11 outside the reciprocating screw 9 slides up and down on the inner wall of the fixed sleeve 7. During the sliding process, the upper end dredges the internal material to further prevent the material from being blocked, and avoid the bridging, rat hole and other blockages of the granular material on the inner wall of the discharge pipe 2 when loading.
