The dagger effectively prevents the liquid glue remaining in the dispensing needle from dripping, and can be a filler valve designer. 〃Back to previous materials [Previous technology] Commonly used dispensing valves are mainly used in various electrical technology fields, and they are roughly divided into air pressure daily adhesives, AU rubber valves, screw dispensing valves, injection points > valves And / Tongue plug positive displacement dispensing valve, 1 '... ^ T' Right base is forward to your child pq 1 Glue viscosity and temperature effect of the glue 'for the maximum amount: 2: The two are generally used in Jingjie, such as the first Six maps, = Displacement valve (5 m tongue plug is set on the injection tube (5)), and a victory tube (Chuan Yu dispensing needle (Beijing (52), and note (5 3), Russi, there are interconnected channels Gansi> Same as 51), the liquid energy can be better than six strikes, and the use of pneumatic cylinders to glue the heart of the material Gu Honghong (5 4) on Note: μ, c ,, move back and forth in the longitudinal direction, so that the liquid glue material in the “(5 1) dispensing needle (5 2), s, > D) can pass through the main purpose. ^ 道 （5 3 ) In order to achieve the main point of dispensing, but the traditional point of error (5 materials are used up, you must / the main idea of the same (5 1) liquid glue method to force the liquid glue ^ 5 〇) operation, And in the gelatin process, directly Who / is in the same injection (5 1), but cannot perform the backfill operation of the liquid glue at the point, which results in its dispensing operation :, the speed of the spoon is delayed, and the glue injection cylinder (5 when filling the glue) It is also very time-consuming on 1M, so it causes great inconvenience to related industries. In addition, when the valve (5 Q) is stopped, it does not provide the function of stopping the glue. ^ Progress has made the liquid saddle material easy to dispense the needle (5 1) For this reason, another manufacturer has modified the disadvantages of the traditional dispensing valve, and developed an improved structure of the dispensing valve, as shown in Figure 7 One side of the injection tube (51) is provided with a connection tube = f) a connection s (5 5)-end connection _ storage of liquid knees > same (not shown in the figure), the other end is connected to the through injection tube (5丄), and respectively take over (55) and the dispensing needle (close the valve (5 6)), so when the note ^ μ " close the liquid glue material in Shijitian / Zhulingtong (5 1) 'The opening and closing valve (5 6) of the takeover (5 5) can be opened, so that the liquid rubber material in the storage cylinder can be smoothly injected into the injection barrel (5 workers), so the function of backfilling can be used. In the production situation where the dispensing booth (50) operates, the monthly dispensing booth for liquid glue is directly used during the dispensing process (when the operation is stopped, the dispensing needle (5 industry on-off valve (5 6)) + α ^ b J), b 6) should be manually closed to prevent the liquid glue from dripping, and can provide the function of stopping glue. Good-quality dispensing rooms must be equipped with a switching valve (51) at the injection tube (51). 56), so its structural phase is * south, and the on-off valve (5 6) is also prone to be blocked by liquid glue. The positive method immediately ㈣ The liquid glue in the needle (53) is free, which will cause the liquid ㈣ to drip and contaminate the product for dispensing MZ46506. As shown in the eighth figure, it is another improved switching point type. It mainly recognizes that ▲ 7 谀 type point valve is set to enter between the main barrel (51) and the dispensing needle (52). , And another switch (5 = spherical switch of rotation switch 阙 (57), and the spherical switch of the ball / = 7-shaped channel (58), thereby, when 5 0) 7) enter the light switch of rotation In this case, the dispensing valve (conducting and the conduction between the barrel (51) and the dispensing needle (53) can be made, and the same can be obtained between the connection between (51) and the reservoir f (...) Without stopping the operation of the dispensing valve (50), under the condition that the dispensing process is over Φ ^ 1 ^% 丨 fday] it, switch to make the wrong two wide (57) for the passage (58), In order to achieve the function of ^ material can be smoothly injected into the injection barrel (5 1) hard to the backfill of the plastic material. However, when the switch type dispensing valve uses its spherical switch to read (57 under the condition of opening and closing the door, the residual valve (5 〇) When it shuts down abnormally, it will cause dripping due to its collection. The internal liquid ㈣ 'is still unable to return immediately [New content] Therefore, I' is changed to * ifr, + * v by missing% i ^ " Valves and various improved dispensing valves Point, the creator of this is called (the point of dispensing M prepared from the sigh leaves a "dispensing valve with backfill stop glue switching function", I hope to set the moon dagger can effectively prevent the residue on the dispensing needle to make the dispensing Concerned with the purpose of abnormal creation ... The dripping of the liquid glue material in the ten masters is for its main purpose to achieve the aforementioned creative purpose. The technical means used in this creation is M246506, which is to provide a backfill stop glue switching function The dispensing valve is mainly composed of an injection barrel, a switching valve, a dispensing needle, and a storage barrel. Among them: an accommodation space is formed inside the injection barrel, and a piston capable of longitudinally reciprocating movement is arranged in the accommodation space. And the bottom is provided with a through hole penetrating the accommodation space; the switching valve is formed from the inside of the seat and is located below the plastic injection cylinder, and can be valley ° inside the seat body and one end penetrates the side of the seat body It consists of a piston, a driver connected to the piston to control its lateral reciprocating action, and an elastic element that can push against the lateral movement of the piston. The top and bottom surfaces of the base body correspond to the through holes of the barrel. Hole-side formation The suction channel is connected to the through hole of the bottom surface of the seat body and the inside of the seat body, and the piston has a channel and a channel. , The switching valve and the dispensing needle are connected, and the injection cylinder, the switching valve, and the storage cylinder are connected, and one end of the piston corresponds to the suction channel-the opening of the end is provided with a necked portion that can form a gap with the inner surface of the seat. j Dispensing needle is set on the switch seat, under the pressure of the corporal Wu valve, there is a glue channel corresponding to the through hole on the bottom of the seat body, and one end of the glue channel forms a glue port. In the glue room, a connection is provided between the hall cylinder and the switching valve. One end of the connection is connected to the bottom of the storage tank, and the other end is connected to the side of the switching valve seat body. The glue reading function of the glue switching function filled by Yidi, its switching valve activity: the first channel passes through up and down and corresponds to the top and bottom through holes of the seat body respectively. The first channel extends from the upper end into the interior and then extends laterally to The side ends correspond to the through holes on the top surface of the base, and the second of the plastic barrel of the library = M246506 penetrates the relative position on one side of the base. · In the dispensing valve with backfill stop switching function, one end of the piston of the switching valve forms an extension that extends through the seat and can be sleeved by the elastic element. The end of the extension forms a flange. The elastic element 2 The ends abut against the end flange of the extension and the side of the seat, respectively. In the dispensing valve with the function of switching backfill and stopping glue, a heating tube is sleeved outside the dispensing needle. In the dispensing valve with the function of switching back filling and stopping glue, a sensor which can detect the amount of the liquid rubber material inside the storage cylinder is arranged below the storage cylinder. With the combination of the above structures, during the dispensing process, due to sudden power failure and abnormal shutdown, the elastic element of its switching valve can push the piston to move laterally in the seat, so that the liquid glue remaining in the dispensing needle is affected. The inward adsorption force does not drip arbitrarily to prevent the liquid glue from dripping and staining. To dispense the product m ϋ The 4 switching valve driver can control the piston to reciprocate laterally in the seat body. In the process of the first and second glue operations, you can cup +77 gu / 4i ^ ρ 彳 彳 Si liquid switching material storage tank into the plastic injection tank to provide excellent liquid material backfill Features.
