Description

Technical Field

[0001] The present invention relates to the technical fields of automobile and medical hose production, and particularly relates to an anti-blocking structure of an extruder. Background Art

[0002] An extruder is an important plastic machine, mainly used for the production and manufacturing of plastic products. Through the pressure and shear force generated by the rotation of the screw, the material is fully plasticized and evenly mixed, and finally formed through the die to produce various plastic products. During the production of automobile and medical hoses, an extruder is needed to achieve the extrusion molding of the hoses.

[0003] Generally, after the extrusion is completed, the residual liquid plastic remains in the die head. Since one end of the die head is in a non-sealed state, the plastic in the die head will solidify, causing the die head to be blocked. This situation generally requires manual cleaning, but the cleaning is difficult and the operation is cumbersome. Summary of the Invention

[0004] The present invention discloses an anti-blocking structure of an extruder, aiming to solve the technical problem that after the extrusion is completed, the residual liquid plastic remains in the die head. Since one end of the die head is in a non-sealed state, the plastic in the die head will solidify, causing the die head to be blocked. This situation generally requires manual cleaning, but the cleaning is difficult and the operation is cumbersome.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An anti-blocking structure of an extruder includes an extruder body. The top of the extruder body is provided with a feed inlet, and the output end of the extruder body is connected to an extrusion die head. The same side outer wall of the extruder body is connected with an anti-blocking mechanism, and the anti-blocking mechanism is connected with a connection mechanism and a shielding mechanism;

[0007] The anti-blocking mechanism includes a motor linear guide fixedly connected to the outer wall of the extruder body. A slider is movably connected to the motor linear guide. A cross bar is fixedly connected to the outer wall of the slider. The top outer wall of the cross bar is fixedly connected with a lower support plate, and the top of the lower support plate is connected with an upper support plate through a hinge. The opposite side outer walls of the upper support plate and the lower support plate are respectively provided with slots, and a U-shaped sliding frame is press-fitted and movably clamped in the slots. The top of the upper support plate is fixedly connected with a circular support plate I, and a plurality of insertion rods are fixedly connected to the outer wall of one side of the circular support plate I at equal intervals around the circumference.

[0008] By providing a clogging prevention mechanism, when the extrusion is finished or the extruder pauses, the upper support plate can be lifted to a vertical state. Subsequently, the motor linear guide is started, and multiple insertion rods can be inserted into the extrusion die head. After the plastic inside solidifies, before the next use, the upper support plate is driven to move outward by the motor linear guide, and the residual plastic in the extrusion die head can be pulled out, thereby avoiding clogging at the extrusion head and reducing the cleaning difficulty at the same time.

[0009] In a preferred solution, the connection mechanism includes grooves three simultaneously arranged in the annular support plate one and each insertion rod. A plurality of inclined slots are equidistantly penetrated through the outer wall of each insertion rod, and one end of the inclined slot is connected to the groove three.

[0010] A metal support bar is respectively movably inserted into each groove three, and a plurality of metal extension bars are equidistantly connected to the circumferential outer wall of the metal support bar. The plurality of metal extension bars are respectively inserted into the plurality of inclined slots correspondingly.

[0011] A plurality of limiting rings are respectively fixedly connected in each groove three, and the inner walls of the plurality of limiting rings are respectively movably attached to the outer wall of the metal support bar. One end of the plurality of metal support bars is simultaneously fixedly connected to an annular support plate two.

A plurality of grooves two are arranged on one side of the annular support plate one, and one end of the plurality of springs is respectively connected to the plurality of grooves two correspondingly.

[0012] A plurality of sleeves are fixedly connected to the outer wall of the annular support plate one. A support shaft is rotatably connected in each sleeve. Two limiting plates two are respectively fixedly connected to each support shaft, and the two limiting plates two are respectively attached to both ends of the sleeve. One end of each support shaft is respectively fixedly connected to a resisting plate.

[0013] By providing a connection mechanism, pushing the annular support plate two to make it fit against one side of the annular support plate one can push forward the plurality of metal support bars and extend the plurality of metal extension bars, thereby optimizing the connection degree between the insertion rod and the plastic to ensure that the plastic does not become displaced during the pulling process of the solidified plastic and further ensuring the thoroughness of plastic cleaning.

[0014] In a preferred solution, the shielding mechanism includes a bottom plate fixedly connected to the bottom end of the motor linear guide. A square through slot and a groove one are simultaneously arranged at the bottom end of the bottom plate. A magnetic sheet two is embedded in the groove one, and a polytetrafluoroethylene cloth is movably inserted into the square through slot.

[0015] One end of the polytetrafluoroethylene cloth is fixedly connected to a limiting plate one, and the limiting plate one is located at the bottom of the square through slot. The other end of the polytetrafluoroethylene cloth is fixedly connected to a plurality of iron wires.

[0016] One end of the motor linear guide is fixedly connected with an extension plate, and the outer wall of the extension plate is fixedly connected with an inclined surface support plate, and a first magnetic sheet is attached to one side outer wall of the inclined surface support plate.

[0017] By providing a shielding mechanism, during normal extrusion production, the upper support plate can be folded downward, and then the polytetrafluoroethylene cloth is unfolded, so that a plurality of iron wires are adsorbed to the first magnetic sheet, and then it can shield above the motor linear guide, avoiding the liquid plastic from dropping and adhering to the anti-blocking mechanism and the connecting mechanism during the extrusion process, which affects the normal operation.

[0018] As can be seen from the above, an anti-blocking structure of an extruder includes an extruder body. A feed inlet is provided at the top of the extruder body, and an extrusion die head is connected to the output end of the extruder body. An anti-blocking mechanism is connected to the outer wall of the same side of the extruder body, and a connecting mechanism and a shielding mechanism are connected to the anti-blocking mechanism; the anti-blocking mechanism includes a motor linear guide fixedly connected to the outer wall of the extruder body, and a slider is movably connected to the motor linear guide. A cross bar is fixedly connected to the outer wall of the slider, an upper support plate is fixedly connected to the top outer wall of the cross bar, and a lower support plate is connected to the top of the lower support plate through a hinge. Slots are respectively arranged on the opposite side outer walls of the upper support plate and the lower support plate, and a U-shaped sliding frame is press-fitted and movably clamped in the slots. An annular support plate one is fixedly connected to the top of the upper support plate, and a plurality of insertion rods are fixedly connected to the outer wall of one side of the annular support plate one at equal intervals around. The anti-blocking structure of the extruder provided by the present invention has the technical effects of avoiding blockage at the extrusion head and reducing the cleaning difficulty at the same time.
