Abstract
The utility model discloses a leak-proof needle stand for glue dispensing device, which comprises a supporting stand which is mounted on the glue dispensing device, a guide rail connected on one side of the supporting stand and a needle stand moving block which can alternatively move along the guide rail, wherein the lower end of the needle stand moving block is provided with a needle hole which allows liquid to flow out, the top end of the needle hole is provided with a joint for connecting an eternal glue pipe for supplying glue, the contact portion of the joint and the needle hole forms a cavity body, and a steel ball and a spring for pushing the steel ball to the joint are arranged in the cavity body. The leak-proof needle stand solves the problem of natural glue leakage after the glue dispensing device stops working and finishes working through the closed control of the joint of a pressed steel ball and the connecting glue pipe.
Description
Technical field
The utility model relates to a kind of point glue equipment, particularly a kind of point glue equipment leakproof punch block that is used for.
Background technology
When existing point glue equipment is finished or worked pause at a glue, be easy to make the interior liquid of sebific duct of point glue equipment because reasons such as gravity drippage influences a graphics shape of glue product.
The Chinese invention patent number of patent application: 200610057231.1 disclose a kind of point glue equipment, have the glue valve of speed control and Flow-rate adjustment.This glue valve comprises the hydraulic valve needle device of a control glue material flow and the pneumaticpiston device of a control point glue speed.The needle device moves through suitably combining to carry out upper-lower interactive with piston apparatus, air pressure turnover piston apparatus makes commutativity needle device when opening and closing, utilize on the needle device at least one throttling profile via needle hollow duct control glue material flow, and with at least one switching speed of a set screw control valve needle device, thereby effective control rate and regulate flow.
But this point glue equipment is not to the solution of residual liquid in the pin hole of point glue equipment because of gravity reason drippage problem.
Summary of the invention
The utility model provides a kind of point glue equipment point glue equipment leakproof punch block that liquid that can not drips in the sebific duct when a glue is finished or worked pause.
A kind of point glue equipment leakproof punch block, comprise the support that is installed on the point glue equipment, the guide rail that is connected support one side, can be along the reciprocal punch block movable block of operation of guide rail, punch block movable block lower end has the pin hole of allowing that liquid flows out, the pin hole top is provided with and is used to connect the outside to the joint of glue with sebific duct, and the contact site of described joint and pin hole is provided with leak-proof device.
Form a cavity at the pin hole of punch block movable block and the contact site of joint, leak-proof device is steel ball in the cavity and the spring that is used for steel ball is pushed to the joint outlet.
This leak-proof device is equivalent to a kind of check valve, finish or work when pausing at a glue at point glue equipment, the exit seal that spring roof pressure steel ball will connect the joint of sebific duct flows out the liquid that can not in the sebific duct, during point glue equipment work in the sebific duct fluid pressure overcome spring force and make liquid flow into cavity to flow out through pin hole again.
For the punch block movable block is back and forth moved along guide rail, can on support, establish one and be subjected to cylinder, its piston rod links to each other with thrust punch block movable block, promotes the punch block movable block and back and forth moves along guide rail.
Be provided with sealing ring between described steel ball and the joint, the enhanced leaktightness effect.
The cavity that forms in the described punch block movable block is step-like.The step of cavity is three grades of steps that cooperate with joint bottom, steel ball, spring respectively.The step place that cavity cooperates with the joint bottom is airtight cooperation, prevents that liquid from overflowing.
Described punch block movable block lower end transverse fold also forms an extension, and pin hole and joint are positioned on this extension.
The utility model is airtight with the control of the joint that is connected sebific duct by the pressurized steel ball, has solved naturally the leak glue problem of point glue equipment after work pauses and finishes.
Description of drawings
Fig. 1 is the plan structure schematic diagram of the utility model point glue equipment with the leakproof punch block;
Fig. 2 be among Fig. 1 A-A to cutaway view;
Fig. 3 is the schematic diagram of point glue equipment among Fig. 2 when steel ball is with joint sealing when work is finished or during pause with the leakproof punch block.
The specific embodiment
Referring to Fig. 1,2, the utility model point glue equipment leakproof punch block, comprise the support 2 that is installed on the point glue equipment, be connected the guide rail 3 of support 2 one sides, be subjected to cylinder 1 thrust can be along the reciprocal punch block movable blocks 4 of operation of guide rail 3, punch block movable block 4 lower end transverse folds also form an extension, be provided with the pin hole 9 of allowing that liquid passes through at extension, pin hole 9 tops are equipped with and are used to connect the outside joint 5 of using sebific duct to glue, be provided with leak-proof device between joint 5 and the pin hole 9, leak-proof device comprises the joint 5 and the cavity that pin hole 9 contacts site form of punch block movable block 4, is provided with in the cavity by spring 8 and the steel ball 7 that is subjected to spring 8 effect roof pressure seal nipples 5.
Be provided with sealing ring 6 between steel ball 7 and the joint 5, the enhanced leaktightness effect.
As preferably, the cavitys that form in the punch block movable block 4 in the present embodiment be three grades step-like, cooperates with joint 5 bottoms, steel ball 7, spring 8 respectively, cavity is airtight the cooperation with joint 5 bottoms, the interior liquid of cavity overflows when preventing work.
Referring to Fig. 3, when point glue equipment is finished or is worked pause at a glue, joint 5 sealing that spring 8 roof pressure steel balls 7 will connect sebific duct is flowed out the liquid that can not in the sebific duct, when point glue equipment is resumed work in the sebific duct fluid pressure overcome spring 8 elastic force and liquid flowed out through pin hole 9 carry out a glue job.
