Description

Technical Field

[0001] The utility model relates to a liquid material extrusion device, in particular to a liquid material extrusion device which can extrude the liquid material. Background Art

[0002] Generally, a liquid material extrusion device needs to be cleaned after being used for a period of time to prevent liquid material from clogging. In order to facilitate the disassembly and assembly of the various mechanisms of the liquid material extrusion device during cleaning, a liquid material extrusion device with a quick disassembly and assembly function is produced.

[0003] For example, Taiwan Patent No. I650180B "Liquid Material Extrusion Device and Its Liquid Chamber Seat Clutch Method and Mechanism" has disclosed a liquid material extrusion device with a quick disassembly and assembly function, which is provided with: a main body; a liquid chamber seat, which is provided below the main body; the liquid chamber seat is provided with two buckle embedding parts, which can be buckled and embedded by two buckle handles extending downwardly provided by a clutch mechanism in the main body; the clutch mechanism is provided with a locking switch on the narrow side of the main body, and an unlocking switch and a clutch switch on the wide side of the main body; the clutch switch is used to operate the buckle handle to engage or separate with the buckle embedding part; the locking switch is used to operate the locking when the buckle handle is engaged with the buckle embedding part to prevent the buckling state from being accidentally released and falling off; the unlocking switch is used to release the original locked state.

[0004] Another example is Taiwan Patent No. I742998B "Liquid Material Extrusion Device and Its Operation Method" which discloses a liquid material extrusion device with a quick disassembly and assembly function, comprising: a main body; a liquid chamber seat, comprising a seat body disposed below the main body, and a valve body disposed on the seat body for containing liquid material; a locking switch disposed on the main body and having two buckle handles that can be clamped on the liquid chamber seat to close the main body and the liquid chamber seat; and an unlocking switch disposed on the locking switch and capable of operating the locking switch to separate the main body from the liquid chamber seat.

[0005] However, in the prior art, the operator needs to operate at least two switches to remove the liquid chamber seat, which is relatively inconvenient to operate and more switches also means a relatively complex mechanism, which shows that there is still room for improvement. Utility Model Content

[0006] Therefore, an object of the present invention is to provide a liquid material extrusion device that can overcome at least one disadvantage of the prior art.

[0007] The liquid material extrusion device according to the purpose of the utility model includes: a valve body, and a liquid chamber seat that can be connected to or separated from the valve body; a buckle handle assembly that can be operated to connect or separate the valve body and the liquid chamber seat; a switch assembly having a rotatable swivel; a first drive component that is separate from the swivel but can be linked; a second drive component that is separate from the buckle handle assembly but can be linked; the swivel can drive the first drive component to link the second drive component to operate the buckle handle assembly to connect or separate the valve body and the liquid chamber seat.

[0008] In the liquid material extrusion device of the embodiment of the utility model, the operator only needs to operate the switch assembly to pivot and then link the buckle handle assembly to connect or separate the valve body and the liquid chamber seat, which is relatively convenient to operate and has a relatively simple structure.

[0075] The buckle handle assembly C is provided with two buckle handles C2 in the shape of long strips and pivotally arranged at the two ends of a buckle handle rod C1; a pressure member C3 is straddled on the upper ends of the two buckle handles C2, and a first elastic member C4 is provided between the upper side of the pressure member C3 and the valve body A to press downward against the pressure member C3; a second elastic member C5 is provided between the two buckle handles C2 to elastically pull the two buckle handles C2 toward each other; a swing support hole C21 and a buckle hole C22 corresponding to the buckle embedded part B5 are provided on the buckle handle C2; ​​the two buckle handles C2 are vertically arranged parallel to each other and abut against the wide sides of the front and rear sides of the valve body A, and the buckle embedded part B5 of the liquid chamber seat B is clamped by the buckle hole C22 by the front and rear sides of the valve body A; the second driving assembly F is linked to the buckle handle assembly C to make the two buckle handles C2 of the buckle handle assembly C move up and down or move closer or farther away from each other;

[0076] The switch assembly D is horizontally extended through the first chamber A3 of the valve body A, the swivel D1 is arranged on a switch shaft D2 of the switch assembly D, and the swivel D1 may be composed of a first cam D11 and two second cams D12 respectively arranged on both sides of the first cam D11 and linked to the first cam D11. The switch assembly D is provided with an operating member D3 at one end of the switch shaft D2, which is exposed on the wide side of the front side of the valve body A for human operation;

[0077] The first drive assembly E extends approximately in the vertical direction, and the second drive assembly F extends approximately in the horizontal direction. The first drive assembly E includes a first arm H1, and the second drive assembly F includes a second arm H2. The first arm H1 and the second arm H2 are formed on a lever arm H pivoted on the valve body A. The lever arm H is slightly L-shaped and is divided into the first arm H1 and the second arm H2 by a pivot axis H3 passing through the valve body A horizontally; there is a fixed The first arm H1 is longer than the second arm H2 at a certain angle (the two are approximately at a right angle), and the force arm H is provided with a roller H4 at one end of the first arm H1 away from the pivot axis H3, and the thickness of the first arm H1 gradually becomes thinner from the pivot axis H3 toward the roller H4; the first driving assembly E also includes a side arm K located on both sides of the first arm H1, and the second driving assembly also includes a swing support L located on both sides of the second arm H2, and the side arm K is separated from the swing support L but can be linked to each other;

[0078] The power mechanism G is provided with a power source G1, such as a piezoelectric actuator, located in the second chamber A4, and a lever G2, located in the third chamber A5 and pressed by the power source G1; the lever G2 can press the upper end of the plunger B4, and the power source G1 drives the lever G2 to drive the plunger B4 to move vertically up and down, so that the plunger B4 can squeeze the liquid material in the liquid chamber B1 to squeeze the liquid material out through the valve mouth B31.

[0079] See also Figure 2 , 4 The first elastic member C4 presses downward against the pressure member C3, so that the pressure member C3 drives the buckle C2 to move downward, thereby linking the buckle rod C1 to press downward against the second arm H2 of the force arm H and providing the force for the force arm H to swing in the clockwise direction; because the force arm H is provided with a force to swing in the clockwise direction, the roller H4 on the first arm H1 can maintain contact with the first cam D11 and roll along the contour of the first cam D11.

[0080] See also Figure 4 , 5The first cam D11 of the switch assembly D is provided with a stopper D111 located at the intersection of the arc surface and the plane; the second cam D12 is provided with an actuating portion D121 located at the intersection of the arc surface and the plane.

[0081] See also Figure 3 , 4 6. The side arm K is disposed between the second cam D12 and the swing support member L. The side arm K is provided with a pressing portion K2 capable of pressing against the swing support member L and a force receiving portion K3 capable of being actuated by the actuating portion D121 at both ends of a vertical side arm body K1. The force receiving portion K3 protrudes horizontally from the side arm body K1 and has a fixed angle with the side arm body K1 (the two are approximately at a right angle).

[0082] The two swing support members L are respectively arranged at the two ends of a pivot axis L1 horizontally passing through the valve body A and can swing up and down relative to the valve body A; a third elastic member L2 is provided between the swing support member L and the valve body A to support the swing support member L upward; the end of the swing support member L away from the pivot axis L1 is provided with a swing support portion L3 horizontally protruding toward the swing support hole C21 of the buckle C2, and the swing support portion L3 is provided with a swing support inclined surface L31 inclined from bottom to top and from inside to outside; the third elastic member L2 supports the swing support member L upward, providing the swing support member L with a force to swing in the counterclockwise direction, so that the swing support member L drives the side arm K to move upward until the swing support member L contacts the inner wall of the valve body A and stops moving.

[0083] In the implementation of the present invention, a person can pivot the operating member D3 of the switch assembly D to place the switch assembly D in the closed position ( Figure 7 ) and the open position ( Fig.10 ) intercropping;

[0084] See also Figure 7 , 8 9. When the switch assembly D is in the closed position, the first cam D11 pushes against the force arm H and the second cam D12 does not contact the side arm K;

[0085] The first cam D11 pushes against the roller H4 on the first arm H1, so that the first arm H1 links the second arm H2 and provides the force for the force arm H to swing in the counterclockwise direction, so that the force arm H swings in the counterclockwise direction, and the second arm H2 supports the buckle rod C1 to drive the buckle C2 to link the pressure member C3 to move upward to accumulate the elastic restoring force of the first elastic member C4, so that the liquid chamber seat B clamped by the buckle C2 is pulled up by the buckle C2 to be close to the bottom side of the valve body A and connected with the valve body A; at this time, the first arm H1 of the force arm H is slightly deformed to the left, and the position where the stopper D111 of the first cam D11 contacts the roller H4 is higher than the pivot axis of the first cam D11 and the roller H4, so that a locking force that is not easy to move is generated between the first cam D11 and the roller H4;

[0086] Because the second cam D12 does not contact the side arm K when the switch assembly D is in the closed position, the swing support member L is supported upward by the third elastic member L2 to contact the inner wall of the valve body A; at this time, the swing support portion L3 of the swing support member L is located at a position horizontally extending into the swing support hole C21;

[0087] See also Fig.10 , 11 12, when the switch assembly D is in the open position, the first cam D11 releases the force arm H and the second cam D12 contacts the side arm K;

[0088] After the first cam D11 is released from pushing against the roller H4 on the first arm H1, the first arm H1 returns to its original shape, the locking force between the first cam D11 and the roller H4 is also released, and the elastic restoring force of the first elastic member C4 causes the buckle rod C1 to drive the buckle C2 to link the pressure member C3 to move downward, so that the buckle rod C1 presses the second arm H2 to link the first arm H1 and provides a force for the force arm H to swing in the clockwise direction, so that the force arm H swings in the clockwise direction, so that the liquid chamber seat B clamped by the buckle C2 moves downward and is no longer attached to the bottom side of the valve body A and is separated from the valve body A;

[0089] The actuating portion D121 of the second cam D12 presses the force-bearing portion K3 of the side arm K, causing the side arm K to move downward, linking the swing support member L to swing in the clockwise direction and accumulate the elastic restoring force of the third elastic member L2; at this time, the swing support portion L3 of the swing support member L leaves the swing support hole C21 downward, and in the process of the swing support portion L3 leaving the swing support hole C21 downward, the swing support inclined surface L31 pushes the two buckle handles C2 away from each other in the horizontal direction and accumulates the elastic restoring force of the second elastic member C5, so that the buckle handle C2 releases the clamp on the liquid chamber seat B, so that it can be removed again after the liquid chamber seat B is separated from the valve body A.

[0090] In the liquid material extrusion device of the embodiment of the utility model, the operator only needs to operate the switch component D to pivot and then link the buckle handle component C to connect or separate the valve body A and the liquid chamber seat B. The operation is relatively convenient and the mechanism is relatively simple.

[0091] However, the above is only a preferred embodiment of the present utility model, and it cannot be used to limit the scope of implementation of the present utility model. That is, all simple equivalent changes and modifications made according to the scope of the patent application of the present utility model and the content of the utility model description are still within the scope of the present utility model patent.
