Description

Wood comb tooth punching device

Technical Field

The invention belongs to the technical field of wood comb processing tools, and particularly relates to a wood comb tooth punching device.

Background

The comb is a necessary product for daily life of people and has strong commercial value. The wooden comb is made of high-grade natural and valuable materials such as boxwood, sandalwood, peach wood, pear wood, agarwood, jujube wood and the like by combining a unique treatment process, has the advantages of no hair pulling, no scalp injury, no static electricity, effective stimulation of head acupuncture points after long-term use, promotion of head blood circulation, brain refreshing, hair nourishing, sleep promotion and the like. Therefore, the wooden comb is popular with consumers and has very wide market prospect.

The comb is formed by a small wood board and a delicate wood comb through a plurality of processes of slotting, colliding, polishing, picking, scaling, sawing back, planing back, polishing, planing and the like. The method has the advantages that the tooth punching is an important process for manufacturing the wooden comb, the existing wooden comb tooth punching is mostly carried out by adopting numerical control tooth punching equipment, the numerical control tooth punching equipment is high in machining efficiency, but the quality of a machined product can not reach the level of the traditional handicraft manufacturing, and therefore the wooden comb in a high-end route is generally in a manual tooth punching mode. The existing wooden comb manual tooth punching tool is usually a saw plate with a certain thickness, and the saw plate is used for manually removing and cutting the wood tooth by tooth. The use of the existing saw blade for tooth cutting mainly has the following disadvantages: 1. the width of the tooth pitch of the teeth is mainly dependent on the experience of workers, and errors are easy to occur; 2. the saw plate is of a single-plate structure, only one tooth can be formed on the saw plate at one time, and the efficiency is not high.

Disclosure of Invention

The invention aims to provide a wood comb tooth punching device to solve the problem that the tooth pitch width is difficult to control when the existing saw plate is used for punching teeth.

In order to achieve the purpose, the scheme of the invention is as follows: a wood comb tooth punching device comprises a main body part and a handle part connected with the main body part, wherein the main body part comprises an adjusting strip and a tooth punching part, the tooth punching part comprises 2 saw plates with sawteeth arranged on one sides, and the distance between the 2 saw plates gradually decreases towards one side with the sawteeth; the adjusting strip is clamped between the 2 saw plates.

The working principle and the beneficial effects of the scheme are that: when the device is used for slotting wood, the position of the adjusting strip is adjusted firstly, and when the tooth pitch width of the slotting is wide, the adjusting strip is moved downwards to be closer to one side of the saw plates with the sawteeth, and the distance between the two saw plates is wide; when the tooth pitch width needing to be notched is narrow, the adjusting strip is moved upwards to be away from the side, with the saw teeth, of the saw plates, and the distance between the two saw plates is narrower. The tooth pitch of tooth is opened can be controlled through the position that changes the regulation strip to this device, can be used for the tooth of opening of different tooth pitches, and application scope is wide. The workman holds handle portion and operates, supports the place that needs the gulleting at timber with 2 one sides that are equipped with the sawtooth on the saw board, then makes a round trip to saw and moves timber, stops to saw after the gulleting degree of depth reaches the requirement and moves. When the next tooth is opened, in order to ensure that the tooth pitch is the same, one of the saw plates (the saw plate is used as a reference) can be opposite to the opened tooth, one side of the other saw plate, which is provided with the saw teeth, is abutted against the position of the wood, which needs to be opened, so that the wood is sawn back and forth, and the sawing is stopped after the tooth opening depth meets the requirement. The wood comb is toothed according to the method, so that the tooth pitches of the teeth on the wood comb are consistent, and the quality of the processed wood comb can be guaranteed. If the wooden comb does not have strict restriction to the pitch, when utilizing this device to open the tooth, make 2 saw boards carry out the operation of opening the tooth simultaneously, 2 teeth can be opened simultaneously in once-through operation, compare in current saw board, machining efficiency can improve one time.

Optionally, the toothed member further comprises a mounting base connected to the handle portion, the 2 saw plates being removably mounted on the mounting base.

The difference between the present embodiment and the first embodiment is: as shown in fig. 4-6, a dust suction mechanism is further disposed on the mounting base 20; the suction mechanism comprises a collecting cylinder 60, a motor 70 and an impeller 71 welded to the output shaft of the motor 70. The mounting seat 20 has a receiving groove 22 and an exhaust port 24 communicating with the receiving groove 22 formed on one side thereof, and the motor 70 is fixedly mounted in the receiving groove 22. The upper end of the collecting cylinder 60 is open, the collecting cylinder 60 is detachably mounted on the mounting seat 20, and the collecting cylinder 60 is communicated with the accommodating groove 22. The inner wall of the accommodating groove 22 is provided with an internal thread, the side wall of the upper part of the collecting cylinder 60 is provided with an external thread matched with the internal thread, and the collecting cylinder 60 is in threaded connection with the mounting seat 20. A conical dust filter 63 is fixed in the collecting cylinder 60 (the dust filter 63 can be a filter screen, a filter cloth, or other objects with filtering performance), the dust filter 63 divides the collecting cylinder 60 into two parts, and one side of the dust filter 63 near the bottom of the collecting cylinder 60 is a tip. An inlet 62 opposite to the dust filter 63 is opened on the side wall of the upper part of the collecting cylinder 60, a valve 61 is installed on the bottom of the collecting cylinder 60, and the material in the collecting cylinder 60 can be discharged through the valve 61.

The output shaft of the motor 70 is provided with a telescopic rod positioned in the accommodating groove 22, and the mounting seat 20 is provided with a through hole 23 through which the telescopic rod extends out of the accommodating groove 22. The telescopic rod comprises a fixing rod 80 and an outer barrel 83 connected to the fixing rod 80 in a sliding mode, the fixing rod 80 is welded to one end of an output shaft of the motor 70, sliding grooves 81 are formed in two sides of the fixing rod 80, and a protruding block 84 connected to the sliding grooves 81 in a sliding mode is welded to the inner wall of the outer barrel 83. A first elastic member 82 (here, the first elastic member 82 is a compression spring) is connected between the fixing rod 80 and the outer cylinder 83, and in the present embodiment, the first elastic member 82 is disposed in the sliding groove 81, and one end of the first elastic member 82 is connected to the projection 84, and the other end is connected to the inner wall of the sliding groove 81. The first elastic member 82 is disposed to enable the outer cylinder 83 to be relatively fixed and not to slide along the fixing rod 80, and the outer cylinder 83 can extend out of the accommodating groove 22 only when a user applies a large pulling force to the outer cylinder 83 to overcome the action of the first elastic member 82.

The telescopic rod is detachably provided with a polishing mechanism, the polishing mechanism comprises a polishing disc 91 and an installation rod 90 welded on the polishing disc 91, and the cross sections of the installation rod 90 and the outer barrel 83 are rectangular. When the sharpening mechanism is mounted on the telescopic rod, the sharpening disk 91 is opposite the exhaust port 24. The mounting bar 90 has a groove 94 formed in one side thereof, and a wedge 93 is slidably received in the groove 94. A second elastic member 92 (in this embodiment, the second elastic member 92 is a compression spring) is disposed in the groove 94, and when no other external force is applied, the inclined side of the wedge block 93 extends out of the groove 94 under the action of the second elastic member 92.
