The working process of the invention is as follows: in an initial state, the cylinder 13 is positioned at the extreme position of the lowest end, and the tail end above the spiral groove on the cylinder 13 is just positioned below the lower end surface of the support cylinder; the limiting ring 11 is contacted with the upper end face of the supporting cylinder; the limiting plate A45 is in contact with the top cover of the supporting cylinder; the shift lever 46 is positioned at the lowest end of the sliding groove B8; the glue mechanism 32 is located at its lowermost limit and opposite the securing mechanism 18. One end of the alarm block 42 is contacted with the side wall of the guide groove 34; spring A23, spring B41, spring C43, and spring E58 are all in a compressed state, and spring D48 is in a stretched state. The plate spring 17 is in a compressed state, so that a certain distance is kept between the arc plate A19 in an initial state and the cylindrical surface of the cylinder 13, and a space is reserved for the edge banding 59 to enter the fixing mechanism 18. The distance between the wedge angle end of the clamping plate 24 and the side spiral wall of the spiral groove is smaller than the thickness of the edge sealing strip 59, so that after the edge sealing strip 59 enters the space between the spiral groove and the clamping plate 24, the wedge angle of the clamping plate 24 playing a barb role clamps the edge sealing strip 59 under the action of the spiral spring 27, and the edge sealing strip 59 is prevented from being drawn away from the fixing mechanism 18 under the action of external force.
At initial state, the guide block 40 is located corresponding guide way 37 and is close to the one end of gluing the mouth of gluing chamber 36, has certain gap between the top of isosceles triangle piece 39 and the guiding groove 34 lateral wall, effectively reduces the effective stroke of isosceles triangle piece 39, guarantees that isosceles triangle piece 39 is opened gluing chamber 36 and is glued the mouth and open, glues the volume of gluing in the chamber 36 and is in a suitable within range, can paint the waste of sufficient glue simultaneously on guaranteeing to seal strake 59 rubberizing face.
When the single-side edge sealing is required to be performed on the inner wall of the round hole B4 on the plate 3, the matched workbench 1 is required to be used, and a round hole A2 with the diameter larger than that of the round hole B4 is required to be formed in the table top of the workbench 1; the plate 3 to be subjected to edge sealing is placed on the table top of the workbench 1, and the round hole B4 in the plate 3 is positioned in the range of the round hole A2 in the table top of the workbench 1, so that the subsequent edge sealing operation of the invention on the inner wall of the round hole B4 in the plate 3 on the workbench 1 is facilitated.
The edge strip 59 is selected to have a thickness greater than the depth of the spiral groove and a width equal to the thickness of the sheet 3 to be edge sealed. Then, the perimeter of the round hole B4 is calculated according to the diameter of the round hole B4 on the plate 3, and the sealing strip 59 with the same length is cut according to the perimeter of the round hole B4; one end of the edge strip 59, which has the same length as the circumference of the circular hole B4, is inserted through the guide groove 34 of the glue mechanism 32 until it meets the top block 28 in the fixing mechanism 18.
During the process that one end of the edge sealing strip 59 penetrates through the guide groove 34, one end of the edge sealing strip 59 interacts with the waist inclined plane of the isosceles triangle block 39 firstly, so that the isosceles triangle block 39 contracts towards the inside of the rubber cavity 36 along the direction perpendicular to the edge sealing strip 59, the spring B41 is further compressed and stores energy, and the rubber outlet of the rubber cavity 36 is opened; the glue in the glue cavity 36 is extruded out of the glue cavity 36 under the auxiliary pressure of the glue injection mechanism 50 and is smeared on the gluing surface of the edge sealing strip 59; with the continuous movement of the edge sealing strip 59, the isosceles triangle block 39 is continuously in an open state to the glue cavity 36, and the glue in the glue cavity 36 is continuously applied to the edge sealing strip 59 under the auxiliary pressure of the glue injection mechanism 50. When the end of the sealing strip 59, which is coated with water, reaches the alarm block 42, the sealing strip 59 acts on the inclined plane of the quadrangular pyramid end 60 of the alarm block 42, so that the alarm block 42 contracts, and the spring C43 is further compressed and stores energy; when one end of the edge banding 59 passes over the alarm block 42, the round end of the alarm block 42 is in adhesive surface contact with the edge banding 59 and presses the edge banding 59.
During the process that one end of the edge banding 59 enters the fixing mechanism 18 and meets the top block 28, one end of the edge banding 59 bends under the guidance of the arc plate B20; when the end of the curved sealing strip 59 reaches the catch plate 24, the end of the sealing strip 59 swings the catch plate 24 around the pin C31, and the two spiral springs 27 are compressed and store energy; the catch plate 24 does not form an obstruction to the sealing strip 59 which continues to move inwardly; when one end of the edge blocking strip 59 reaches the top block 28, the edge blocking strip 59 stops moving due to the blocking of the top block 28; at this point, the wedge-shaped angled end of catch plate 24 is pressed against sealing strip 59 by the action of the two volute springs 27. When external force is applied to the fixing mechanism 18 to pull the edge banding 59 away, the clamping plate 24 tightly pressing the edge banding 59 swings around the pin C31 under the driving of the edge banding 59 and further extrudes the edge banding 59; since the end of the catch plate 24 that engages with the edge seal 59 is a wedge-shaped angle, the wedge-shaped angle of the catch plate 24 that swings back around the pin C31 fits into the edge seal 59 to provide a barb, thereby preventing the edge seal 59 from being pulled out of the fixing mechanism 18 and temporarily fixing the edge seal 59.
As shown in fig. 1, when one end of the edge banding 59 reaches the top block 28 of the fixing mechanism 18, the present invention is placed on the plate 3, so that the lower end surface of the supporting cylinder is in contact fit with the plate surface of the plate 3, and the cylinder 13 is located in the circular hole B4 on the plate 3 and the circular hole a2 on the working table 1. Then, the crank 12 is shaken, and the crank 12 drives the screw 10 to rotate through the limiting ring 11; since the screw 10 is in threaded fit with the threaded hole 6 in the middle of the top cover of the support cylinder, the screw 10 moves vertically upward relative to the support cylinder while rotating; the screw 10 drives a cylinder 13 arranged at the lower end of the screw to move synchronously; the cylinder 13 drives the fixing mechanism 18 arranged on the cylinder to move synchronously, and the fixing mechanism 18 drives one end of the edge sealing strip 59 to move synchronously; under the traction of the fixing mechanism 18 and the guidance of the spiral groove, the edge strip 59 performs a spiral motion relative to the cylinder 13, and the edge strip 59 is wound in the spiral manner in the spiral groove.
In the process of spirally winding the edge banding 59 on the cylinder 13, the edge banding 59 is drawn by the fixing mechanism 18 to move relative to the gluing mechanism 32; the edge banding 59 continuously moves along the guide groove 34 in the glue coating mechanism 32, and the glue in the glue cavity 36 continuously coats glue on the gluing surface of the edge banding 59, so that the edge banding 59 wound on the cylinder 13 is ensured to be completely coated with the glue.
When the lower end of the edge sealing strip 59 is separated from the isosceles triangular block 39, under the reset action of the spring B41, the isosceles triangular block 39 is instantly reset and closes the glue outlet of the glue cavity 36; when the lower end of the edge banding 59 is separated from the alarm block 42, under the reset action of the spring C43, the alarm block 42 is reset instantly and simultaneously generates a strong alarm sound along with the instant impact of the alarm block 42 and the side wall of the guide groove 34, and the tail end of the edge banding 59 is separated from the alarm block 42 and is about to be separated from the rubber coating mechanism 32. At this point, the rocking of the handle 12 is stopped so that the lower extremity of the edge strip 59 remains partially within the guide slot 34 in the gluing mechanism 32, to ensure that the edge strip 59 continues to remain wound on the cylinder 13.
Then, the invention is integrally slid along the upper surface of the plate 3, so that the L plate 44 provided with the glue coating mechanism 32 is firstly contacted with the inner wall of the round hole B4 on the plate 3, and then the invention is integrally swung around the L plate 44 along the direction opposite to the rotation direction of the spiral rising of the cylinder 13 until the invention can not be swung continuously, and at the moment, the edge sealing strip 59 is wound on the cylinder 13, and the part close to the glue coating mechanism 32 is contacted with the inner wall of the plate 3 and is mutually adhered; manually poking the poking rod 46 upwards, so that the poking rod 46 drives the gluing mechanism 32 to move upwards through the L plate 44 and is separated from the tail end of the edge sealing strip 59, and the spring D48 is further stretched and stores energy; then, the outer wall of the supporting cylinder is dragged by two hands, the glue coating mechanism 32 is kept in a state of being separated from the tail end of the edge sealing strip 59 upwards, the circular plate 3 is moved along the circumferential direction of the inner wall of the circular hole B4 of the plate 3, and the moving direction is the same as the rotating direction when the cylinder 13 spirally ascends. In the process of moving the invention along the circumferential direction of the inner wall of the round hole B4 of the plate 3, the cylinder 13 is pressed against the inner wall of the round hole B4 of the plate 3, and along with the movement of the equipment, the edge sealing strip 59 with the lower end stuck on the inner wall of the round hole B4 pulls the cylinder 13 and the screw 10 to rotate reversely; because the screw 10 is in threaded fit with the threaded hole 6 on the top cover of the supporting cylinder, the screw 10 drives the cylinder 13 to perform spiral descending motion at the moment; with the spiral descending movement of the cylinder 13 and the circumferential movement of the whole body of the invention along the inner wall of the round hole B4, the edge banding 59 spirally wound on the edge banding is gradually and circumferentially stuck on the inner wall of the round hole B4 of the plate 3; in the process of pasting on banding strip 59 to round hole B4 inner wall, the one end that lies in fixing mechanism 18 on banding strip 59 can take place for fixing mechanism 18's tendency of taking out apart for banding strip 59 is pasting the in-process to round hole B4 inner wall, and cardboard 24 plays the barb effect and fixes banding strip 59, makes banding strip 59 can stimulate cylinder 13 antiport effectively.
When the fixing mechanism 18 protruding out of the cylindrical surface of the cylinder 13 reaches the upper surface of the plate 3, the fixing mechanism 18 slightly moves towards the center of the circular hole B4, so that the fixing mechanism 18 is located in the range of the circular hole B4, and then the crank 12 is reversely shaken, so that the screw 10 drives the fixing mechanism 18 to spirally descend into the circular hole B4 through the cylinder 13; then, the invention is moved towards the inner wall direction of the round hole B4, so that the inner wall of the round hole B4 extrudes the fixing mechanism 18; the fixing mechanism 18 swings around the pin A29 towards the inside of the movable groove 15 under the extrusion of the inner wall of the round hole B4, the arc plate A19 continuously extrudes the edge sealing strip 59 through the arc plate B20 hinged with the arc plate A and the clamping plate 24 hinged with the arc plate B20, the wedge-shaped angle end of the clamping plate 24 swings around the pin C31 towards the direction far away from the cylinder 13 relative to the arc plate B20 under the action of the edge sealing strip 59, and the two spiral springs 27 further generate and store energy; when the concave arc surface of the arc plate is contacted with the edge banding 59, the wedge angle of the clamping plate 24 completely enters the swing groove 21 on the arc plate B20; due to the action of the two spiral springs 27, the clamping plate 24 still plays a barb role on the sealing strip 59 and forms clamping and fixing on the sealing strip 59; when the arc plate A19 swings around the pin B30 relative to the arc plate B20 under the extrusion action of the inner wall of the round hole B4 and is in contact with the press block 26, located between the arc plate A19 and the arc plate B20, on the clamping plate 24, the arc plate A19 drives the wedge-shaped angle end of the clamping plate 24 to continuously swing around the pin C31 towards the direction far away from the cylinder 13 through the press block 26, the wedge-shaped angle end of the clamping plate 24 enters the swing groove 21 on the arc plate B20 and is separated from the edge sealing strip 59, and the clamping plate 24 releases the fixation of the edge sealing strip 59; as the invention continues to move along the circumferential direction of the inner wall of the round hole B4 and the cylinder 13 rotates reversely, the sealing strip 59 is quickly separated from the fixing mechanism 18 and is pressed by the cylinder 13 to be stuck on the inner wall of the round hole B4.
When the edge banding 59 is completely pasted on the inner wall of the round hole B4 of the plate 3, the limiting ring 11 installed on the screw 10 is just reset, and the cylinder 13 stops rotating.
