Description

Technical Field

[0001] The utility model relates to the field of water-cutting devices, in particular to a water-cutting device applied to a headband of an earphone. Background Art

[0002] Common plastic products or injection molded products in daily life will leave sprues on the products during processing. Sprues refer to the excess material left on the products during forming. In order to ensure the integrity and good appearance of the products, the remaining sprues need to be cut off after processing.

[0003] The nozzle of the upper cover of the headphone headband is distributed outside the upper cover. The traditional method of cutting the nozzle is manual cutting, that is, manually taking the formed plastic product and cutting and removing the nozzle with diagonal pliers, and then picking up the plastic product and putting it into the next process. Figure 1-2 shown.

[0004] However, it is impossible to maintain the consistency of the cutting position by manually cutting the nozzle, and thus, the fine quality of the upper cover is difficult to ensure. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a nozzle cutting device applied to the headphone headband, which is intended to replace the manual nozzle cutting and solve the problem of insufficient quality caused by manual cutting.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a water cut device applied to a headphone headband, characterized in that it has:

[0007] A jig for supporting the upper cover, wherein a side of the jig is abutted against a water outlet outside the upper cover;

[0008] A pressing block adjacent to the upper cover is pushed by the driving mechanism to abut against the upper cover;

[0009] and, providing a cutting edge and a nozzle cutting mechanism for cutting off the nozzle against the side of the fixture;

[0010] Wherein, a positioning groove is provided on the jig, and the upper cover is positioned by constraining the protrusion at the bottom of the upper cover.

[0011] Furthermore, the pressing block is rotated on the upper cover by the driving mechanism, and then presses the upper cover onto the fixture by a linear downward pressing motion.

[0012] Furthermore, a path formed by the rotation of the pressing block is parallel to the surface of the upper cover.

[0013] Furthermore, the driving mechanism is a rotating downward-pressing cylinder.

[0014] Furthermore, the top surface of the fixture is a curved surface adapted to the shape of the upper cover.

[0015] Furthermore, the water outlet cutting device includes a telescopic cylinder, a knife holder, and a cutting knife. The piston rod of the telescopic cylinder is connected to one side of the knife holder, and the cutting knife is arranged on the other side of the knife holder and maintained in a relative state with the water outlet. The telescopic cylinder drives the knife holder to move toward the water outlet to cut off the water outlet from the upper cover.

[0016] Furthermore, it also includes a guide assembly, which includes at least one pair of spaced-apart limiting plates and a guide column located between the two limiting plates, and the tool holder is sleeved on the guide column.

[0017] Beneficial effects of the utility model:

[0018] The jig, the pressing block and the water outlet cutting mechanism that constitute the utility model constitute the function of the water outlet cutting. During this process, the pressing block is controlled by the driving mechanism, and the upper cover is fixed to a specific position in combination with the positioning between the positioning groove and the upper cover protrusion. Therefore, the blade of the water outlet cutting mechanism can accurately reach the water outlet, and the water outlets of different upper covers can be cut off at the same position, thereby solving the problem of insufficient quality of the upper cover caused by manual cutting and improving the efficiency of water outlet cutting.

[0026] See also Figure 3-7 As shown, the headphone headband water outlet cutting device of this embodiment is used to cut the water outlet 11 of the upper cover 1 of the headphone headband, and the water outlet 11 of the upper cover 1 extends outward from the inner annular surface of the upper cover 1 or from the edge of the upper cover 1.

[0027] The two parts of the utility model are a positioning mechanism and a water-cutting mechanism arranged on a workbench 14. The positioning mechanism includes a fixture 2 for supporting the upper cover 1 and a clamping assembly for restricting the upper cover 1 on the fixture 2.

[0028] The top surface of the jig 2 is an arc surface that matches the shape of the upper cover 1. After the upper cover 1 is installed on the jig 2, the water outlet 11 of the upper cover 1 rests on the side of the jig 2. The clamping end in the clamping assembly provides pressure from the top of the upper cover 1 to ensure that when the water outlet 11 cutting mechanism horizontally cuts the water outlet 11, the upper cover 1 will not separate from the jig 2; during the cutting process, the side of the jig 2 provides a certain supporting force to the water outlet 11 to ensure that the water outlet 11 can withstand sufficient cutting force and be cut off.

[0029] The clamping assembly includes a rotary pressing cylinder 3, a connecting rod 4, and a pressing block 5. The rotary pressing cylinder 3 is installed on a workbench 14 and close to the fixture 2. The piston rod of the rotary pressing cylinder 3 is connected to the pressing block 5 through the connecting rod 4. The rotary pressing cylinder 3 drives the pressing block 5 to rotate to the top of the fixture 2, and presses the upper cover 1 onto the fixture 2 through the downward pressing action. The above scheme provides a way to constrain the upper cover 1 in the positioning groove 7, which has a simple structure and strong practicality.

[0030] In the embodiment, the area where the pressing block 5 applies pressure to the upper cover 1 is the vertex of the upper cover 1 .

[0031] The arc surface is also provided with a positioning groove 7 opposite to the protrusion 6 of the upper cover 1. The upper cover 1 is sunk into the positioning groove 7 through the protrusion 6, thereby achieving the effect of positioning the upper cover 1 and ensuring that the upper cover 1 can be quickly assembled to the specified position.

[0032] The protrusion 6 is arranged on the bottom surface of the upper cover 1. The protrusion 6 is a component that connects the upper cover 1 and the lower cover of the headphone headband or a reinforcing rib that enhances its own strength.

[0033] To sum up, the water outlet 11 device provided by the utility model is a method of cutting the water outlet 11 by pure equipment cutting. Compared with the traditional water outlet 11 method, the utility model has higher precision. The design of the positioning groove 7 can ensure the position of the upper cover 1 on the fixture 2. Combined with the use of the water outlet 11 device and the clamping assembly, the consistency of the cutting position can be guaranteed. It can be seen that after using the utility model to replace manual cutting, the fine quality is fully guaranteed.

[0034] The water outlet 11 installation device includes a telescopic cylinder 8, a knife seat 9, and a cutting knife 10. The piston rod of the telescopic cylinder 8 is connected to one side of the knife seat 9, and the cutting knife 10 is arranged on the other side of the knife seat 9 and maintained in a relative state with the water outlet 11. The telescopic cylinder 8 drives the knife seat 9 to move toward the water outlet 11 to cut off the water outlet 11 from the upper cover 1.

[0035] The movement of the knife seat 9 relies on the guidance of the guide assembly, which includes a pair of spaced limit plates 12 and a guide column 13 located between the two limit plates 12. The knife seat 9 is sleeved on the guide column 13, and the guide column 13 guides the knife seat 9 to move in a specific direction to prevent the cutter 10 from deviating.

[0036] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
