M256251 Creation instructions (1) The technical field of the new type] This creation is related to a sander. _ Borrow the sand belt drum of the cylindrical sander and], in particular, refers to the grinding of the workpiece by lifting Quality, prolong the function of sand and j complex yaw, and it can be used, and prevent the card from being jammed during heavy cutting :: the grinding ability, the use of reciprocating yaw device. Prior art] There is a belt 6 on the side. Please refer to the first figure. The machine base 11 is known. The base is above the center of the body: 10 roughly includes a motor mount i 3 and a belt 1 2. Its--motor ", inside is provided with 19 mouths ^ 〆 裒 商 座 15, just located on the conveyor side, in addition, the roller seat 15 is equipped with a sand inside the shaft; ϊ: end and the axis of the motor 14 1 4 i connection, so that the motor ^: day: moving cylinder 16 to rotate, thereby, when the user wants to grind wood: 'You can directly place the workpiece on the conveyor 2 and then pass through the conveyor 2 The grinding operation is performed under the belt roller i 6. [New content] Although you have a sanding machine with a function of grinding workpieces, the structure of the structure still has the following unsatisfactory features and needs to be improved: 1. The belt roller 16 does not have a reciprocating deflection function. Therefore, when it is grinding with the parts, it is easy to concentrate the contacting and grinding part on the belt roller 1. In this way, the belt roller 16 will be in constant contact. Quickly know the position, and then lose the grinding performance, eventually leading to the use of the belt roller 16

M256251 IV. Creative Instructions (2) Life span is greatly reduced. 2 · As mentioned above, because the belt roller 16 does not have a reciprocating yaw function, therefore, it is easy to accumulate wood chips to accumulate in a certain place during grinding, which greatly reduces the cutting and grinding effect, and even causes the belt. The sticking phenomenon occurs between the roller 16 and the workpiece, among which the heavy cutting and grinding are obvious.疋 取 3 · During the grinding process, the workpiece will only be subjected to forward and backward cutting (that is, parallel to the conveying direction), but not horizontal grinding. The surface of the workpiece after grinding is horizontally $. It is easy to have irregularities, and the flatness of the surface of the workpiece cannot be effectively improved. It is ΐίί ϊ Ϊ supply—a kind of cylindrical reciprocating deflection device for rollers. The inside of the motor fixed seat of the VXf * machine is the body extension-lower I, and it slides downwards to the upper seat and the upper seat. The end-to-end shaft is provided with a belt f H to form a roller seat. After that, Litian Ju and each Α / π develop a shaft assembly. When the motor is fixed?连接 The connection between the belt and the belt drum-the input end of the coupling mechanism and the coupling assembly: structure: the transmission power transmission belt is connected to the output end of the reduction mechanism and the upper door. In addition to the output power, it can pass through _ & A pivotal link set enables the horse belt to transmit power to the deceleration mechanism ;: = In addition, the upper seat can be actuated through the link set to reduce the speed with the abrasive belt, and then reciprocated by the eccentric pivot: η : Pendulum exercise. The regular reciprocating yaw movement, "two sets," is mainly to make the belt drum smooth, without causing bumps and bumps. = After the surface of the piece is ground, the flat area is enlarged, so the force is naturally = external.

In addition, the belt roller is 'especially during heavy cutting due to the reciprocating yaw movement'. The whole is less prone to chipping, sticking, or even jamming. Therefore, it can also extend the service life of the belt drum and make the grinding operation smoother and faster. [Embodiment] Please refer to the second to fourth figures.

The structural features, the use of technical means and the use methods are described. I believe that if you understand it specifically, please refer to the following: Please cooperate with the fourth and sixth pictures, when the sander of this creation is operated, the motor 50 is started first. Rotate the shaft center 51 to indirectly drive the belt pulley 6 1 to rotate through the coupling assembly 70. At this time, the pulley 7 2 4 on the second coupling 7 2 can also be driven to reduce speed through the belt 8 4 at the same time. The timing pulley 83 on the input end 81 of the mechanism 80 rotates, and indirectly transmits the output power of the motor 50 to the reduction mechanism 80. After that, it passes through the reduction mechanism 80. The internal gear set (not shown) After proper deceleration, the power is transmitted to the eccentric wheel 8 5 of the wheel output end 8 2. At this time, as shown in the seventh figure, the first link 9 1 of the link group 90 is eccentrically pivoted to the eccentric wheel. Therefore, when the first link 9 is subjected to the eccentric movement of eccentric wheel § 5 and the second, third, and fourth links 92, 93, and 94 are sequentially linked, the first

M256251 、 Instruction of creation (6) The four-link 9 4 will swing regularly with the center of the motor fixed seat, and then borrow the pivot pin 4 1 == 0 as the rotation axis, so that it can link the fifth link 9 4 The appropriate swinging cylinder 6 1 of the connecting rod 9 4 makes a reciprocating oscillating movement; the animal moves the upper seat 6 2 together with the belt roll and the belt drum 6 i to the motor fixed seat 2. It is explained that when the upper seat 6 2 is as shown in the eighth figure As shown, when the direction of the coupling assembly 7 P is close to the deflection, the second coupling of the first coupling member 7 1 with the piston 7 1 1 will be compressed inward, and it will be squeezed immediately. Nitrogen ':: Two gas η force, this reverse thrust can be used to absorb the vibration of the abrasive belt J--gradually increasing the moment of the end of the reverse thrust xf 6 1 彺 deflection to the stroke belt roller to the motor fixed seat = 2: The upper seat 62 together with the first coupling 7 of the sand assembly 7 0 :: The deflection is deflected toward the return, the coupling is separated from the second coupling "piece L; also: J extends outward 7 2 Nitrogen 3 in i will be given one by two ::: the vibration of the piece ^. 杬 to the moment of the pause of the end of the swaying sway 1 has Γ effectively slow down the belt roller 61 reciprocating partial connection Soap makes the overall grinding operation smoother. I summarize the advantages and achievable effects of this creation as follows: Therefore-ΓΓ belt belt roller 61 has a reciprocating offset displacement function, =, the workpiece is ground and its contact is ground The part will often be in the state of β 1 and it will produce concentrated grinding, so it can effectively prevent the abrasive belt from rolling quickly and the abrasion part will quickly wear, thereby achieving the purpose of extending the use of the abrasive belt on it. 2 The belt roller 61 has a reciprocating deflection function. Page 10 M256251, Creative Instructions (7) In contrast, it is attached to a certain contact part when the workpiece is ground, which can ensure that the chips are less likely to accumulate stickiness. In addition, it can also effectively prevent the cutting and grinding performance of the conventional stone less belt =, in addition to this phenomenon. Occurrence of seizure between the workpiece and the workpiece 3 · Because of the low reciprocity of this creation and the cutting and grinding of the workpiece forward and backward, Xi With the roller 61, except for this, the work after grinding is as follows: Surface ::: When horizontal movement grinding is applied, it is known that the surface of the workpiece is prone to unevenness. Effectively solve the bumps, resulting in flatness. In summary, the above-mentioned creation has very good utility in similar products. 1 It is also used to check the technical information of such structures at home and abroad. :: The same structure has not been found Existing first, yes ", this innovation ^ New Patent Elements' apply according to law.
