Description

Technical Field

[0001] The utility model belongs to the technical field of speaker paper cone manufacturing, in particular to a slurry-sinking type speaker paper cone forming machine. Background Art

[0002] The speaker cone is an important part of the speaker, which is responsible for converting electrical energy into sound waves. The forming technology of the cone directly affects the sound quality of the speaker. Traditional cone forming methods include manual stamping and mechanical pressing. Although these methods can produce cones of various shapes, they have problems such as low production efficiency, difficult to ensure precision, and high labor intensity.

[0003] The existing patent of "A Slurry-sinking Paper Cone Forming Machine" with the publication number "CN102776807A" includes a papermaking pulp barrel, a mechanical arm flipping mechanism, a hot pressing forming mechanism, and a dry material picking mechanism, wherein the mechanical arm flipping mechanism is located above the papermaking pulp barrel, and the formed trumpet paper cone is transported to the hot pressing forming mechanism by the mechanical arm flipping mechanism, and then the trumpet paper cone is collected from the hot pressing forming mechanism by the dry material picking mechanism. The fully automatic production of trumpet paper cones is realized, and the utilization efficiency of human and material resources is improved.

[0004] However, the above-mentioned paper basin forming machine still has some shortcomings in actual use: since the mold is driven by the robotic arm flipping mechanism to extend into the papermaking pulp barrel, and the flipping mechanism is also immersed in the pulp, the pulp will adhere to the flipping mechanism and penetrate into the flipping mechanism. Long-term penetration will affect the components in the flipping mechanism, and during the movement, excess pulp attached to the edge of the mold and the flipping mechanism will easily fall to other places in the device and need to be cleaned.

DETAILED DESCRIPTION

[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] Reference Figure 1-Figure 3 A slurry-sinking speaker paper cone forming machine comprises a base 1, a papermaking pulp barrel 4, a paper cone forming mechanism, a hot pressing forming mechanism and a mold. Six support rods 2 are fixedly connected to the top surface of the base 1, and a top plate 3 is fixedly connected to the top of the support rod 2. The papermaking pulp barrel 4 is fixedly connected to the base 1. A drainage groove 22 is connected to the opening of the papermaking pulp barrel 4.

One side of the papermaking pulp barrel 4 is located on the top surface of the base 1 and is fixedly connected to a hot pressing platform 5;

[0024] The paper basin forming mechanism includes a connecting frame 7, a threaded rod 8 and a first motor 9. The bottom ends of the two support rods 2 close to the papermaking pulp barrel 4 are fixedly connected with the fixing rod 6, and the middle part is slidably connected with the connecting frame 7. A threaded hole is penetrated at the middle position of the connecting frame 7. The connecting frame 7 is threadedly connected with the threaded rod 8 through the threaded hole. The bottom end of the threaded rod 8 is rotatably connected with the fixing rod 6, and the top end penetrates the top plate 3 and is fixedly connected to the output shaft of the first motor 9. The connecting frame 7 is fixedly connected with a connecting plate 10 on one side close to the papermaking pulp barrel 4. The bottom end of the connecting plate 10 is fixedly connected with a mold bottom plate 11. The upper surface of the mold bottom plate 11 is fixedly connected to the mold. The mold adopts an upper end placement type. The mold can accommodate one or more trumpet paper basins. A negative pressure suction device is fixedly connected to the mold, and the negative pressure suction device consists of a cylinder and an air pipe.

[0025] Two guide grooves 12 are formed on the top plate 3, and both ends of the guide grooves 12 are fixedly connected to a fixing plate 13 on the surface of the top plate 3, and two sliding rods 14 are fixedly connected between the two fixing plates 13. A lead screw 15 is rotatably connected between the two sliding rods 14 between the two fixing plates 13, and a second motor 16 is fixedly connected to the top plate 3 at the outer side of the fixing plate 13, and one end of the lead screw 15 passes through the fixing plate 13 and is fixedly connected to the output shaft of the second motor 16;

[0026] The hot pressing forming mechanism includes a movable frame 17, a hot pressing top 19 and a mold base 20. The upper end of the movable frame 17 is provided with two through holes and a threaded hole. The through holes are slidably connected to the slide rod 14, and the threaded holes are threadedly connected to the lead screw 15. Both sides of the movable frame 17 slide in the guide groove 12. The movable frame 17 is fixedly connected with a cylinder 18. The movable rod of the cylinder 18 is fixedly connected to the hot pressing top 19. The hot pressing top 19 is also provided with a negative pressure suction device that can absorb the speaker cone. The mold base 20 is fixedly connected to the hot pressing platform 5.

[0027] By setting the paper basin forming mechanism as a plate connection structure that can only be lifted and lowered, so as to limit its position within the range of the papermaking pulp barrel 4, after the mold is lifted to produce pulp and the paper box is initially formed, the hot pressing forming mechanism moves from the hot pressing platform 5 to the top of the mold to absorb the paper box and then moves back to the original position, so that the pulp no longer soaks into the mechanism device and the excess pulp is prevented from falling to the outside of the papermaking pulp barrel 4 when the mold is moved, and there is no need for personnel to clean it, thereby reducing the workload of the staff;

[0028] Six support rods 2 are all fixedly connected to the edge of the base 1, two of which are located between the papermaking pulp barrel 4 and the hot pressing platform 5, and the other four are located at the four corners of the top surface of the base 1. A mechanical arm 21 is rotatably connected to a support rod 2 away from the papermaking pulp barrel 4, and the end of the mechanical arm 21 is fixedly connected to the mold, in which the mold is also controlled by a cylinder through an air pipe to adsorb the trumpet paper cone.

[0029] The functional principle of the utility model can be explained through the following operation modes:

[0030] When in use, the first motor 9 is controlled to make the connecting frame 7 descend through the threaded rod 8, so that the mold bottom plate 11 and the mold are completely immersed in the pulp, and the negative pressure suction device on the mold generates negative pressure through the cylinder, so that a layer of pulp is adsorbed on the mold. After the speaker paper cone is initially formed, the connecting frame 7 drives the mold bottom plate 11 to rise, and the cylinder on the mold is changed to positive pressure, so that the mold no longer adsorbs the speaker paper cone, and the second motor 16 is controlled to make the movable frame 17 in the hot pressing molding mechanism move to the top of the mold on the mold bottom plate 11 through the screw 15. The hot pressing top 19 moves downward under the drive of the cylinder 18 and cooperates with the negative pressure suction device thereon to suck up the speaker paper cone, and then moves back to its original position to be just above the mold base 20;

[0031] By setting the paper cone forming mechanism as a plate connection structure that can only be lifted and lowered, so as to limit its position within the range of the papermaking pulp barrel 4, and using a hot pressing forming mechanism to transfer the trumpet paper cone, the paper pulp can be prevented from being immersed in the mechanism device and the excess paper pulp can be prevented from falling to the outside of the papermaking pulp barrel 4 when the mold is moved, and there is no need for personnel to clean it, thereby reducing the workload of the staff;

[0032] The hot pressing top 19 is pressed down again under the drive of the cylinder 18, and cooperates with the mold base 20 to press and dry the speaker paper cone. After completion, the hot pressing top 19 releases the suction and rises, and then the robotic arm 21 transfers the mold fixed on it to the speaker paper cone, and sucks up the paper cone through the negative pressure suction device, and then transfers it to the top of the collection device through the robotic arm 21, releases the suction of the negative pressure suction device, and the speaker paper cone falls, and the collection is completed.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
