Different from the existing manual bagging method, the wound acrylic yarn can be automatically and quickly bagged and packaged and transported to the feeding conveyor table. On the one hand, it can reduce the workload of employees in the packaging process and reduce labor costs; on the other hand, it can reduce manual operations to achieve the effect of reducing assembly errors and improving production efficiency.

[0020] 2. By setting up a cylindrical cam, a cylindrical pin, a driven frame, a No. 2 spring and a vertical block for use together, the horizontal movement of the mobile conveyor table can be converted into a 90° intermittent flipping movement of the exchange plate. The mechanical linkage is strong, so that the four groups of bag-supporting stations on the exchange plate can be adaptively used alternately according to the movement state of the mobile conveyor table, thereby meeting the purpose of continuous packaging and transportation of acrylic yarn.

[0021] 3. When the mobile conveyor platform is connected with the loading conveyor platform, the distance between the vertical block and the mobile conveyor platform is set to be no less than the length of the bag support plate. The purpose of this setting is to push the cylindrical cam to rotate only after the mobile conveyor platform is completely away from the bag support plate, thereby making space for the exchange plate to rotate normally; and by arranging four quarter-turn spiral grooves distributed in a circular array and four straight grooves on the outer wall of the cylindrical cam and using them in conjunction with cylindrical pins, the cylindrical cam can drive the exchange plate to rotate 90° when the driven frame moves to the right, and when the driven frame moves to the seat, the cylindrical cam and the exchange plate remain stationary, so that the next wave of materials can be normally loaded into the packaging bag.

[0022] 4. By setting up the door-type moving block, the inclined slot, the toggle column and the main push plate for use together, the linear driving force of the auxiliary push rod can be converted into the linear movement of the two adjacent sets of bag support plates towards or away from each other, so that they can compress or loosen the packing bags well.

The cylindrical pin 21 slides in the spiral grooves and the linear grooves, one end of the driven frame 22 is fixedly connected to the cylindrical pin 21, and the other end of the driven frame 22 extends into the base 1 and is fixedly connected to the vertical block 24. A long slot for accommodating the vertical block 24 is opened on the upper surface of the base 1, and the vertical block 24 is in contact with the right side wall of the mobile conveying platform 4. Two groups of No. 2 springs 23 are symmetrically arranged on the left side wall of the assembly platform 3, and the end of the No. 2 spring 23 away from the assembly platform 3 is fixedly connected to the inner wall surface of the driven frame 22.

[0043] Furthermore, by setting up the cylindrical cam 19, the cylindrical pin 21, the driven frame 22, the No. 2 spring 23 and the vertical block 24 for use in cooperation, the horizontal movement of the mobile conveying platform 4 can be converted into a 90° intermittent flipping movement of the exchange disk 16. The mechanical linkage is strong, so that the four groups of bag-holding stations on the exchange disk 16 can be adaptively used alternately according to the movement state of the mobile conveying platform 4, thereby meeting the purpose of continuous packaging and transportation of acrylic yarn.

[0044] Specifically, when the mobile conveyor platform 4 is in contact with the loading conveyor platform 2, the spacing between the vertical block 24 and the mobile conveyor platform 4 is set to be no less than the length of the bag support plate 10. The purpose of this setting is to push the cylindrical cam 19 to rotate only after the mobile conveyor platform 4 is completely away from the bag support plate 10, thereby making room for the exchange plate 16 to rotate normally; and by arranging four quarter-turn spiral grooves distributed in a circular array and four straight grooves on the outer wall of the cylindrical cam 19 for use in conjunction with the cylindrical pin 21, when the driven frame 22 moves to the right, the cylindrical cam 19 can drive the exchange plate 16 to rotate 90°, and when the driven frame 22 moves to the seat, the cylindrical cam 19 and the exchange plate 16 remain stationary, so that the next wave of materials can be normally loaded into the packaging bag.

The moving block 11 is limitedly slidably installed in the placement groove, one end of the bag-holding plate 10 extends into the placement groove and is fixedly connected to the door-type moving block 11, one end of the door-type moving block 11 is fixedly connected to a No. 1 spring 15, and the other end of the door-type moving block 11 is penetrated by inclined grooves 12 on both sides above and below, and a toggle column 13 is inserted in the inclined groove 12, one end of the main push plate 14 is fixedly connected to the toggle column 13, and the other end of the main push plate 14 extends out of the rear side wall of the exchange disk 16 and contacts the auxiliary push rod 20, and the auxiliary push rod 20 is a small electric push rod and is fixedly installed on the assembly table 3.

[0046] Furthermore, by setting up the door-shaped moving block 11, the inclined slot 12, the toggle column 13 and the main push plate 14 for use in combination, the linear driving force of the auxiliary push rod 20 can be converted into a linear movement toward or away from two adjacent groups of bag-supporting plates 10, so that they can well compress or loosen the packaging bags.

[0047] like Figure 2 as well as Figure 4 As shown, a push plate 27 and an electric push rod 28 are provided at the connection between the loading conveying platform 2 and the moving conveying platform 4. The push plate 27 is a door-shaped plate, and the rear end cover of the electric push rod 28 is fixedly set on the assembly platform 3. The piston rod of the electric push rod 28 extends outward and is fixedly connected to the rear side wall of the push plate 27.

[0048] Specifically, the electric push rod 28 is turned on to push the push plate 27 to move toward the moving conveying platform 4 , so that the push plate 27 pushes the plurality of linearly distributed wire bobbins into the packing bag 7 continuously.

[0049] When the present invention is in use: a plurality of independently wound acrylic yarn bobbins are transported to the assembly platform 3 via the loading conveyor platform 2, and then the electric push rod 28 is turned on to push the push plate 27 to move toward the moving conveyor platform 4, so that the push plate 27 quickly pushes a plurality of linearly distributed bobbins into the packing bag 7. When the packing bag is full, the motor is turned on to drive the transverse lead screw 26 to rotate clockwise, and under the screwing action of the internal and external threads, the nut seat 25 drives the moving conveyor platform 4 to the feeding conveyor platform 5, so that the bagged bobbins are quickly transferred to the feeding conveyor platform 5 for the next step of processing;

[0050] In this process, the upright block 24 drives the driven frame 22 to move toward the feeding conveyor 5 under the push of the mobile conveyor 4, and the cylindrical pin 21 on the driven frame 22 enters the spiral groove of the cylindrical cam 19, so that the exchange plate 16 drives the bag support plate 10 to perform a 90° flip movement. At this time, the open end of the packing bag 7 can be opened up and down and sleeved on the two sets of bag support plates 10 at the upper end through the cooperation of the guide rod 8, the bag feeding frame 9, the suction cup 901, the deflection arm 902 and the translation seat 903;

[0051] Then turn on the motor again to drive the transverse screw 26 to rotate counterclockwise, and under the screwing action of the internal and external threads, the nut seat 25 drives the mobile conveyor platform 4 to move toward the upper material conveyor platform 2. In this process, as the mobile conveyor platform 4 releases the force of the opposing block 24, under the elastic force of the No. 2 spring 23, the driven frame 22 drives the vertical block 24 to move away from the feeding conveyor platform 5, and the cylindrical pin 21 on the driven frame 22 drives into the linear groove of the cylindrical cam 19. At this time, the exchange plate 16 and the bag support plate 10 remain stationary, and the next wave of materials can enter the packaging and assembly work normally.

[0053] S1: Multiple independent wire bobbins are transported to the assembly platform 3 via the loading conveyor platform 2, and the wire bobbins are pushed into the packing bags 7 by the push plate 27. When the packing bags are full, the motor is turned on to drive the transverse screw 26 to rotate clockwise, so that the mobile conveyor platform 4 moves toward the feeding conveyor platform 5, so that the bagged wire bobbins are quickly transferred to the feeding conveyor platform 5 for the next step of processing;

[0054] S2: The vertical block 24 drives the driven frame 22 to move toward the feeding conveyor 5 under the push of the mobile conveyor 4, so that the exchange plate 16 drives the bag support plate 10 to perform a 90° flip movement. At this time, the bag taking assembly is activated to open the open end of the packing bag 7 up and down and sleeve it on the two sets of bag support plates 10 at the uppermost end;

[0055] S3: Then turn on the motor again to drive the transverse screw 26 to rotate counterclockwise, so that the mobile conveyor platform 4 moves toward the upper material conveyor platform 2 and releases the force of the opposing block 24. Under the elastic force of the second spring 23, the driven frame 22 drives the upright block 24 to move away from the feeding conveyor platform 5. At this time, the exchange plate 16 and the bag support plate 10 remain stationary, and the next wave of materials can enter the packaging and assembly work normally.

A conveying device for producing and packaging acrylic yarn according to claim 7, Features: One end of the main push plate (14) is fixedly connected to the toggle column (13), and the other end of the main push plate (14) extends out of the rear side wall of the exchange plate (16) and abuts against the auxiliary push rod (20). The auxiliary push rod (20) is a small electric push rod and is fixedly installed on the assembly table (3).

9. The conveying device for producing and packaging acrylic yarn according to claim 1, Features: A push plate (27) and an electric push rod (28) are provided at the connection between the loading conveying platform (2) and the moving conveying platform (4); the push plate (27) is a door-shaped plate; a rear end cover of the electric push rod (28) is fixedly arranged on the assembly platform (3); and a piston rod of the electric push rod (28) extends outward and is fixedly connected to the rear side wall of the push plate (27).

10. A method for using the acrylic yarn production and packaging conveying device according to any one of claims 1 to 9, Features: The method comprises the following steps: S1: A plurality of independent bobbins are transported to the assembly platform (3) via the loading conveyor platform (2), and the bobbins are pushed into the packing bags (7) via the push plate (27). When the packing bags are full, the motor is turned on to drive the transverse screw (26) to rotate clockwise, so that the mobile conveyor platform (4) moves toward the feeding conveyor platform (5), thereby quickly transferring the bagged bobbins to the feeding conveyor platform (5) for the next step of processing; S2: The vertical block (24) drives the driven frame (22) to move toward the feeding conveyor (5) under the push of the mobile conveyor (4), so that the exchange plate (16) drives the bag support plate (10) to perform a 90° flipping movement. At this time, the bag taking assembly is activated to open the open end of the packing bag (7) up and down and sleeve it on the two sets of bag support plates (10) located at the uppermost end; S3: Then the motor is turned on again, so that it drives the transverse lead screw (26) to rotate counterclockwise, so that the movable conveyor platform (4) moves toward the upper material conveyor platform (2) and releases the force of the opposing block (24). Under the elastic force of the second spring (23), the driven frame (22) drives the upright block (24) to move away from the feeding conveyor platform (5). At this time, the exchange plate (16) and the bag support plate (10) remain stationary, and the next wave of materials can enter the packaging and assembly work normally.
