Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1 to 6, a spinneret plate for producing a melt-blown filter element comprises a base plate 1, wherein a square groove 13 is arranged in the center of the base plate 1 along a long axis, a melt feed hopper 12 is arranged at one end of the base plate 1, two air inlet pipes 11 are symmetrically arranged at two sides of the melt feed hopper 12, one end of the square groove 13 is blocked, the other end of the square groove 13 is communicated with the feed hopper, a plurality of conical spinneret orifices 14 are uniformly communicated with the bottom surface of the square groove 13, two pipe cavities 5 parallel to the square groove 13 are arranged in the base plate 1, the pipe cavities 5 are symmetrically arranged at two sides of the square groove 13, a plurality of air outlet pipes 51 are communicated with the pipe cavities 5 in parallel, the air outlet pipes 51 are symmetrically arranged at two sides of the conical spinneret orifices 14, the lower ends of the conical spinneret orifices 14 and the air outlet pipes 51 are both opened at the bottom surface of the base plate 1, a blocking component is arranged on the conical spinneret orifices 14, and the upper end of the blocking component penetrates out of the top of the base plate 1 and is connected with the base plate 1 in a sliding manner, and a lifting assembly is arranged on the plugging assembly.

In this embodiment, the plugging component includes a tapered plug 4, when plugging is performed, the tapered plug 4 is disposed in the tapered spinneret 14, a connecting rod 3 is disposed on the tapered plug 4, the upper end of the connecting rod 3 penetrates through the top of the base plate 1 and is slidably connected with the base plate 1, a connecting plate 21 is disposed at the upper end of the connecting rod 3, and a lifting component is disposed on the connecting plate 21.

In this embodiment, the front end of the connecting plate 21 is provided with a shutter 22, and the shutter 22 is slidably connected with the base plate 1 and the square groove 13.

In this embodiment, the lifting assembly includes a frame 2 and a screw 24, the frame 2 is disposed on the base plate 1, the lower end of the screw 24 is rotatably connected to the connecting plate 21, and the upper end of the screw 24 is in threaded connection with the top of the frame 2.

In this embodiment, the top end of the screw 24 penetrates through the frame 2 and is provided with a rotating handle 23.

The working process and principle are as follows:

the air inlet pipe 11 is connected with an air heater and hot air is introduced, the hot air enters the air outlet pipe 51 from the pipe cavities 5 on the two sides and is blown out from the lower end of the air outlet pipe 51, the melt feed hopper 12 is connected with the melt heating device and the metering pump, the liquid PP melt is pumped into the square groove 13 by the metering pump, the melt flows into each conical spinning nozzle 14 from the square groove 13 and flows out from the lower end opening of the conical spinning nozzle 14, and the flowing melt is drawn by hot air blown out of the air outlet pipe 51 and is wound on a carrier to form a filter element cylinder. When a long-specification filter element needs to be produced, the screw rod 24 is rotated, the screw rod 24 drives the connecting plate 21 to move upwards, the connecting plate 21 drives the connecting rod 3 and the flashboard 22 to move upwards, the connecting rod 3 drives the conical plug 4 to move upwards and move out of the conical spinneret 14, then the conical spinneret 14 is opened, the melt flows forwards at the moment, enters the square groove 13 below the connecting plate 21, flows out of the conical spinneret 14 which is just opened, and is then drawn and wound on a longer carrier to form the long-specification filter element. When a filter core with a shorter specification needs to be processed, the screw 24, the downward flashboard 22, the conical plug 4, the plugging square groove 13 and the conical spinning nozzle 14 are rotated in the reverse direction, so that the spinning distance can be reduced, a shorter filter core can be obtained, and the filter cores with various specifications can be produced without adjusting the reciprocating movement amplitude of the carrier in the production process.
