Description

Feeding tray for guitar scale line

Technical Field

The utility model relates to a guitar accessory production machinery, in particular to pay-off dish of guitar musical scale line.

Background

The guitar scale line is the fret. The musical scale wire (fret) is a thin metal strip embedded at precise intervals throughout the fingerboard, most of which is usually made of nickel-silver (Nickelsilver, commonly occurring as NS) alloy (practically free of any silver), which is actually a nickel-copper alloy. Conventional alloys used to make fine scale wires are typically 18% nickel, 80% copper and other metals such as zinc, lead and cadmium. Jesca's nickel silver scale wire formula is 62% copper, 18% nickel and 20% zinc.

As shown in fig. 3, the musical scale wires have a rounded crown 1 ' on the top of a slightly thinner tang 2 ' and barbs 3 ' on both sides, each musical scale wire having a cut length corresponding to the width of the neck and then being driven into a pre-cut groove of the fingerboard. The crown 1 'is larger than the groove width, i.e. the crown 1' is wider than the tang 2 'and the tang 2' is slightly shorter than the groove width. Barbs 3 'on either side of the tang 2' ensure that the scale wire is secured in the groove.

When a cylindrical metal wire is processed into a scale line, a tang 2 ' and barbs 3 ' on two sides of the tang 2 ' are firstly rolled out from the metal wire to obtain a semi-finished scale line, then the semi-finished scale line pressed out by the roller is cut, so that the length of each scale line is matched with the width of a neck, and a handle foot 2 ' is ground, so that the width of the tang 2 ' is matched with a groove on a finger board, and the tang 2 ' is narrower than a crown 1 '.

The cylindrical metal wire or the semi-finished scale line can be placed in a feeding tray before rolling or cutting and stamping, and enters a machine table for stamping and cutting under the action of a traction device.

SUMMERY OF THE UTILITY MODEL

Therefore, to foretell problem, the utility model provides a simple structure, low in production cost can stably carry columniform wire or, and can greatly improve the feed table of guitar musical scale line of yields.

In order to realize the technical problem, the utility model discloses the solution that takes is guitar musical scale line's feed table, including lower charging tray and last discharge tray, lower charging tray set up in the below of going up the discharge tray, go up the discharge tray and fix and set up in outside frame, be provided with the spiral track in going up the discharge tray, form the spiral channel that supplies semi-manufactured goods musical scale line to pass through between the spiral track.

The further improvement is that: put down the charging tray rotatable set up in go up the charging tray, it is provided with the inductor that is used for responding to semi-manufactured goods musical scale line to go up the position that the charging tray is located spiral passage and is close to last charging tray axle center to go up the charging tray, it is provided with the fourth drive arrangement who makes go up the charging tray and rotate relatively with lower charging tray to go up between charging tray and the lower charging tray, the inductor with fourth drive arrangement signal connection.

The further improvement is that: the driving device is a motor, a shell of the motor is fixedly arranged on the upper discharging disc, and a driving shaft of the motor is fixedly connected with the lower discharging disc.

By adopting the technical scheme, the beneficial effects of the utility model are that: but automatic adjustment ejection of compact speed avoids because the deformation of semi-manufactured goods scale line that discharge speed and traction speed discordance lead to when semi-manufactured goods scale line pulls of draw gear, has improved the yields.

Fig. 2 is a cross-sectional view of a discharge tray a-a of fig. 1 according to an embodiment of the present invention.

Fig. 3 is a schematic diagram of the background art of the embodiment of the present invention.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

Example (b):

referring to fig. 1 and 2, disclosed in the embodiment of the present invention is a feeding tray for guitar musical scale lines, comprising a lower tray 42 and an upper tray 41, wherein the lower tray 42 is disposed below the upper tray 4, the upper tray 4 is fixedly disposed on an external frame, a spiral track 43 is disposed in the upper tray 41, a spiral channel for passing the semi-finished musical scale lines is formed between the spiral track 43, the lower tray 42 is rotatably disposed on the upper tray 41, an inductor 44 for inducing the semi-finished musical scale lines is disposed on the spiral channel 4 near the axis of the upper tray 41, a third motor 45 for rotating the upper tray 41 and the lower tray 4 is disposed between the upper tray 41 and the lower tray 42, a housing of the third motor 45 is fixedly disposed on the upper tray 41, and a rotating shaft of the third motor 45 is fixedly connected to the lower tray 42, the sensor 44 is in signal connection with the third motor 45, the semi-finished scale line of the traction device is dragged, the semi-finished scale line receives a pulling force and moves towards the axis direction close to the upper discharging disc 41 in the spiral channel, the sensor 44 senses the semi-finished scale line and sends a signal, the third motor 45 rotates and pushes out the semi-finished scale line, the semi-finished scale line moves towards the axis direction far away from the upper discharging disc 41 in the spiral channel, the sensor 44 does not sense the semi-finished scale line and sends a signal, the third motor 45 stops rotating, and the reciprocating is performed in such a way, so that the deformation of the semi-finished scale line caused by the fact that the speed of the semi-finished scale line is inconsistent with the speed of the traction device is avoided, the guitar yield is improved, and the working efficiency of the stamping cutting machine of the scale line is also guaranteed.

Based on the above solution, in actual operation, the driving device may also be driven by an internal combustion engine.

Modifications and variations of the present invention are within the scope of the claims and are not limited by the disclosure of the embodiments.
