As shown in fig. 2, 3 and 13, a screw B41 is arranged in the middle of the cooling barrel 1, an internal thread sleeve B55 is screwed on the screw B41, and a ring sleeve 45 is rotatably nested on the internal thread sleeve; three telescopic rods 47 are uniformly and circumferentially hinged on the outer wall of the ring sleeve 45 along the spiral direction, and the three telescopic rods 47 are respectively and spherically hinged with three sliding sleeves 53 which are nested and slide in the middle of the spiral sleeve 4 and are uniformly and circumferentially distributed; the telescopic rod 47 has a return spring 52 therein for retracting and returning the telescopic rod.

As shown in fig. 14 and 15, the inner spiral wall of the spiral casing 4 has a spiral cooling groove B6, and round holes are densely distributed on the circumferential wall of the spiral casing 4, which is advantageous for cooling the edge banding 20 inside the spiral casing 4.

As shown in fig. 3, the telescopic rod 47 is composed of an outer sleeve 48 and an inner rod 50 which are inserted into each other; a return spring 52 is located in the outer sleeve 48; one end of the return spring 52 is connected with the inner wall of the outer sleeve 48, and the other end is connected with the end surface of the inner rod 50. Two guide blocks 51 are oppositely installed on the inner rod 50, the two guide blocks 51 respectively slide in the two guide grooves 49 on the inner wall of the outer sleeve 48, so that the reset spring 52 in the telescopic rod 47 is always in a stretching state, and the outer sleeve 48 and the inner rod 50 in the telescopic rod 47 are prevented from being separated in the stretching process.

As shown in fig. 2, 8 and 14, the screw sleeve 4 is installed in the cooling barrel 1 by a plurality of installation seats 16 which are spirally spaced. As shown in fig. 1, 5 and 11, cooling drum 1 has a cooling channel a3 at its upper end that is in communication with and tangential to cooling drum 1 to ensure that sealing strip 20 exiting extruder 19 is cooled a substantial distance before entering spiral jacket 4 to avoid deformation of sealing strip 20 entering spiral jacket 4. Two twisting wheels 18 for clamping the edge sealing strip 20 are arranged in the cooling groove A3; the edge strip 20 exiting extruder 19 enters spiral jacket 4 tangentially around two guide wheels 17 and two twist wheels 18 in cooling bath a3, ensuring that edge strip 20 exiting extruder 19 enters spiral jacket 4 tangentially to the sidewalls of the spiral inside spiral jacket 4, further avoiding deformation of edge strip 20 prior to complete cooling. As shown in fig. 6 and 15, the top wall in the screw sleeve 4 is hinged with a plurality of abutting plates 7 matched with the edge sealing strip 20 at even intervals along the screw direction of the screw sleeve 4, so that the edge sealing strip 20 entering the screw sleeve 4 is guaranteed to slide along the bottom in the screw sleeve 4 all the time under the abutting of the abutting plates 7, and the edge sealing strip 20 is prevented from shaking in the screw sleeve 4. A scroll spring A10 which swings and resets the pressing plate 7 is arranged on a fixed shaft A9 on which the pressing plate 7 is arranged; one end of the volute spring A10 is connected with the fixed shaft A9, and the other end is connected with the inner wall of the annular groove A8 in the corresponding pressing plate 7. As shown in fig. 5 and 6, rollers a11 for reducing friction between the edge banding 20 and the inner wall of the spiral casing 4 are installed at even intervals along the spiral direction of the spiral casing 4 on the side wall of the spiral casing 4 pressed by the edge banding 20, so as to reduce friction between the inner wall of the spiral casing 4 and the edge banding 20. As shown in fig. 15, the volute spring B15 is seated in groove B13 in the respective baffle a 12; one end of the volute spring B15 is connected with the inner wall of the corresponding ring groove B13, and the other end is connected with the corresponding fixed shaft B14.

As shown in fig. 7 and 8, the baffle B21 is provided with a gasket a23 which is in sealing engagement with the corresponding outlet B2 to prevent the coolant in the cooling tub 1 from leaking through the closed outlet B2. Each outlet B2 is hinged with a hook 24 through a fixed shaft C26, and the hook 24 is matched with the clamping groove 22 on the corresponding baffle B21; the volute spring C27 for swinging and resetting the hook 24 is nested on the corresponding fixed shaft C26 and is positioned in the annular groove C25 in the corresponding hook 24; one end of the volute spring C27 is connected with the inner wall of the corresponding annular groove C25, and the other end is connected with the corresponding fixed shaft C26.

As shown in fig. 8 and 10, a pair of rubber plates 28 are closely attached to each other in the outlet B2 to prevent the coolant in the cooling tub 1 from leaking when the edge banding 20 enters and exits the outlet B2. A sealing gasket B29 matched with the end face of the guide sleeve 30 is arranged at the outlet B2 in the cooling barrel 1, so that the cooling liquid in the cooling barrel 1 is prevented from entering the guide sleeve 30 through a gap between the guide sleeve 30 and the barrel wall of the cooling barrel 1 and leaking through the outlet B2. A plurality of pairs of rubber plates 28 which are tightly attached to each other are arranged in the guide sleeve 30 along the length direction of the guide sleeve, so that the cooling liquid in the spiral sleeve 4 can not enter the guide sleeve 30 and leak along with the movement of the edge banding 20 in the process that the edge banding 20 enters and exits the guide sleeve 30. As shown in fig. 8 and 12, one end of the guide sleeve 30 is provided with a round corner 31 matched with the sealing gasket B29, so that the sealing gasket B29 does not form an obstacle to the abutting joint of the guide sleeve 30 and the outlet B2. As shown in fig. 9, 10 and 12, the side wall of the guide sleeve 30 has a water pumping groove 32 communicating the inside and the outside thereof, and the water pumping groove 32 is connected to a water pump 40 mounted on the cooling tub 1 through a water pumping pipe 39. The water pump 40 can pump out the cooling liquid entering the guide sleeve 30 and circulate the cooling liquid back into the cooling barrel 1.

As shown in fig. 1, 2 and 9, screws a36 are rotatably fitted on three rotary seats 37 vertically spaced in the cooling barrel 1, and the screws a36 are screwed with an internal thread bush a34 installed outside the guide bush 30; as shown in fig. 8, 10 and 12, the trapezoidal guide block 33 installed outside the guide sleeve 30 vertically slides in the trapezoidal guide groove of the guide rail 35, and the guide rail 35 is fixed in the cooling tub 1; as shown in FIG. 9, the upper end of the screw A36 has a manual crank 38 mounted thereon.

As shown in fig. 2, 3 and 13, the internal thread sleeve B55 is provided with a hand-operated torsion wheel 42, and the screw B41 is provided with two circular rings a43 for limiting the axial movement amplitude of the internal thread sleeve B55. Two circular rings B44 are arranged on the internal thread sleeve B55, and the circular rings B44 rotate in a circular groove D46 on the inner wall of the ring sleeve 45. The rotational engagement of ring B44 with groove D46 ensures that only relative rotation occurs between ring sleeve 45 and internally threaded sleeve B55 and no relative axial movement occurs. As shown in fig. 4 and 13, four sets of rollers B54 are uniformly arranged on the inner circumference of the sliding sleeve 53 and are engaged with the outer side wall of the spiral casing 4, so as to reduce the friction between the sliding sleeve 53 and the spiral casing 4.

The water pump 40 of the present invention is a conventional one.

The working process of the invention is as follows: in an initial state, the internal thread sleeve B55 is positioned at the upper end limit position of the screw B41 and is abutted against the upper circular ring A43, the three sliding sleeves 53 are circumferentially and uniformly nested in the middle position range of the spiral sleeve 4, the three telescopic rods 47 are all in a shortest contraction state, and the return springs 52 in the three telescopic rods 47 are all in a pre-stretching state. The guide sleeve 30 connects the outlet a5 at the upper end of the screw sleeve 4 with the corresponding outlet B2, and the internal thread sleeve a34 abuts against the rotary seat 37 at the lowest end.

In the initial state, the two baffles B21 respectively close the corresponding outlets B2, the two hooks 24 respectively insert into the slots 22 on the corresponding baffles B21 and lock the closed state of the corresponding baffles B21, and the two volute springs C27 are both in the compression energy storage state. The baffle A12 closes the outlet A5 in the middle of the spiral shell 4 and the volute spring B15 is in a compressed energy storage state. The scroll springs A10 on the pressure plate 7 are all in a compression energy storage state.

If the edge banding 20 is made of a material that can be cooled and set over a short distance, then when the present invention is used to cool the edge banding 20 extruded from the extruder 19, it is necessary to open the shutter B21 at the outlet B2 near the bottom of the cooling barrel 1 and keep the guide sleeve 30 in abutting communication with the outlet B2 near the bottom of the cooling barrel 1 and the corresponding outlet a5 on the spiral sleeve 4. At the same time, the closed state of the shutter a12 to the corresponding outlet a5 is maintained.

In the case that the material of the edge strip 20 only needs to pass through a short distance to complete the cooling and sizing, the edge strip 20 only needs to exit from the outlet a5 at the bottom of the screw shell 4 after being guided by the screw shell 4. After the edge banding strip 20 extruded from the extruding machine 19 sequentially bypasses the two guide wheels 17 and the two twisting wheels 18 inside and outside the cooling groove A3 and enters the spiral sleeve 4, because the edge banding strip 20 is cooled to a certain degree in the cooling groove A3, the edge banding strip 20 entering the spiral sleeve 4 generates a certain degree of pressing on the inner side wall and the outer side wall of the spiral sleeve 4 in the process of continuously moving towards the inside of the spiral sleeve 4, and the rollers A11 on the inner side wall and the outer side wall of the spiral sleeve 4 effectively reduce the friction between the edge banding strip 20 and the inner side wall and the outer side wall of the spiral sleeve 4.

When the edge sealing strip 20 passes through the abutting plate 7 in the spiral sleeve 4, the abutting plate 7 can vertically swing upwards around the corresponding fixing shaft A9 under the action of the edge sealing strip 20, the volute spring A10 installed on the abutting plate 7 is further compressed to store energy, the abutting plate 7 abuts against the passing edge sealing strip 20 and abuts against the edge sealing strip 20 on the bottom spiral surface in the spiral sleeve 4, the phenomenon that the edge sealing strip 20 moves in the spiral sleeve 4 to shake is avoided, and the edge sealing strip 20 moving in the spiral sleeve 4 is guaranteed to be effectively cooled under the condition that deformation is not generated due to shaking of the edge sealing strip 20.

When the sealing strip 20 comes out from the outlet a5 near the bottom of the spiral case 4 through the guidance of the spiral case 4, the end of the sealing strip 20 enters the guide sleeve 30 and thus ejects a plurality of pairs of rubber plates 28 in the guide sleeve 30, and the ejected rubber plates 28 are tightly attached to the side surface of the sealing strip 20 in sequence, so as to prevent the cooling liquid in the cooling barrel 1 from entering the guide sleeve 30.

The sealing strip completely passes through the guide sleeve 30 and then enters the outlet B2 near the bottom of the cooling barrel 1, the pairs of rubber plates 28 in the outlet B2 are pushed open and come out of the cooling barrel 1, the rubber plates 28 pushed open by the sealing strip 20 in the outlet B2 are tightly attached to the side face of the sealing strip 20, and the cooling liquid in the cooling barrel 1 is effectively prevented from leaking through the outlet B2. The edge strip 20 is cooled for a longer distance and for a longer time by the helical guidance of the entire screw jacket 4, and the edge strip 20 completes its cooling setting when it comes out from the outlet B2 near the bottom of the cooling tub 1.

If the material of the edge banding 20 needs to be cooled and set over a longer distance, when the edge banding 20 extruded from the extruder 19 is cooled by using the present invention, the baffle B21 at the outlet B2 of the middle portion of the cooling barrel 1 needs to be opened, and the portion above the middle portion of the spiral casing 4 needs to be axially stretched to increase the axial pitch of the portion above the middle portion of the spiral casing 4, so as to ensure that the edge banding 20 does not generate large cooling deformation during the cooling process of the spiral casing 4. When the upper half of the spiral casing 4 is axially stretched to the limit, the outlet A5 at the middle of the spiral casing 4 is just opposite to the outlet B2 at the middle of the cooling barrel 1, and then the guide sleeve 30 is vertically moved upwards and the outlet B2 at the middle of the cooling barrel 1 is in butt joint communication with the corresponding outlet A5 on the spiral casing 4.

The procedure for axially stretching the upper portion of the spiral casing 4 is as follows:

the torsion wheel 42 is rotated, the torsion wheel 42 drives the internal thread sleeve B55 to axially move downwards on the screw B41, the internal thread sleeve B55 drives the ring sleeve 45 which is rotationally matched with the internal thread sleeve B55 to synchronously axially move, the ring sleeve 45 simultaneously drives the three sliding sleeves 53 to vertically move downwards through the three telescopic rods 47 which are connected with the ring sleeve 45 in a spherical hinge mode, the three sliding sleeves 53 simultaneously form vertical downwards stretching on the middle portion and the upper portion of the screw sleeve 4, and the portion below the middle portion of the screw sleeve 4 is axially compressed. In the process of axial deformation of the screw sleeve 4, the three telescopic rods 47 can further stretch to a certain degree, and the three sliding sleeves 53 can slide in a self-adaptive small-angle spiral manner to a certain degree on the screw sleeve 4.

When the internal thread bush B55 abuts against the lower end ring A43, the axial deformation operation of the screw sleeve 4 can be completed by stopping rotating the torsion wheel 42, and at the moment, the outlet A5 at the middle part of the screw sleeve 4 is just opposite to the outlet B2 at the middle part of the cooling barrel 1. To this end, the axial drawing operation of the middle upper portion of the screw sleeve 4 is completed.

The flow of the guide sleeve 30 moving vertically upwards and communicating the middle outlet A5 of the spiral sleeve 4 with the middle outlet B2 of the cooling barrel 1 is as follows:

when the outlet A5 at the middle of the screw sleeve 4 is completely opposite to the outlet B2 at the middle of the cooling barrel 1, the baffle at the bottom outlet B2 is closed, and the baffle B21 is locked by the corresponding hook 24. Manually pressing baffle a12 into spiral casing 4 opens central outlet a5 of spiral casing 4, and coil spring B15 of baffle a12 is further compressed and enters outlet a5 as sealing strip 20 exits spiral casing 4 and continues to travel to central outlet a 5. Extrusion of edge banding 20 by extruder 19 is temporarily stopped when an end of edge banding 20 enters central outlet a5 of spiral casing 4. Flap a12 swings back against the side of edge strip 20 under the action of volute spring B15 and remains open to outlet a 5.

Then, the crank handle 38 is shaken, the crank handle 38 drives the screw A36 to rotate, the screw A36 drives the guide sleeve 30 to move vertically and upwards through the internal thread sleeve A34 screwed with the screw A, and the guide sleeve 30 gradually separates from the bottom outlet A5 of the spiral sleeve 4 and the bottom outlet B2 of the cooling barrel 1. When the internal thread sleeve A34 abuts against the rotary seat 37 at the middle position, the guide sleeve 30 just connects the outlet A5 at the middle of the spiral sleeve 4 and the outlet B2 at the middle of the cooling barrel 1 in butt joint. At this time, the outlet a5 at the middle of the screw sleeve 4 and the outlet B2 at the middle of the cooling tub 1 are in butt-joint communication by stopping the rocking of the crank 38. Then, the baffle B21 at the middle outlet B2 of the cooling tub 1 is opened.

When the guide sleeve 30 is in communication with the central outlet A5 and the central outlet B2, the extruder 19 is restarted to extrude the edge banding 20, and the edge banding 20 exits the cooling drum 1 through the guide sleeve 30 at the central outlet B2. The edge banding 20 exiting the center exit port B2 will need to continue to cool and set due to the short cooling distance. The edge banding 20 from the middle outlet B2 enters the second initial state of the present invention for continuous cooling and shaping, and the edge banding 20 from the outlet B2 near the bottom of the second inventive cooling barrel 1 is finished.

When the edge banding 20 has cooled, the shutter a12 automatically closes the outlet a5 under the action of the return of the volute spring B15 as the edge banding 20 comes out completely of the central outlet a5 of the screw sleeve 4.

The edge sealing strip 20 is continuously cooled by the spiral sleeves 4 or two continuous spiral sleeves 4 in the invention, so that effective cooling and shaping in a limited space are completed, the space occupied by equipment in a factory building in the edge sealing strip 20 cooling process is effectively reduced, the cooling efficiency of the edge sealing strip 20 is improved, and the cooling manufacturing cost of the edge sealing strip 20 is reduced.

If the axial state of the screw sleeve 4 is restored, the torsion wheel 42 is reversely rotated, and the torsion wheel 42 drives the screw sleeve 4 to be axially restored through a series of transmission. When the internal thread sleeve B55 is reset along the axial direction of the screw B41, the screw sleeve 4 is reset in the axial direction. Then, the inner threaded sleeve A34 is turned reversely, when the inner threaded sleeve A34 is pressed against the rotary seat 37 at the bottom again, the guide sleeve 30 is reset and is in butt joint communication with the outlet A5 at the bottom of the screw sleeve 4 and the outlet B2 at the bottom of the cooling barrel 1 again. And after the guide sleeve 30 and the spiral sleeve 4 are reset, the two baffles B21 are closed to the two outlets B2.

Locking flow to the flap B21: the corresponding hook 24 is swung away from the wall of the cooling barrel 1 manually, the vortex spring C27 is further compressed, the baffle B21 closes the outlet B2, and then the hook 24 is pressed into the slot 22 on the baffle B21 under the reset action of the vortex spring C27 and completes the locking of the baffle B21.

The opening procedure for flap B21 is as follows:

the hook 24 is swung away from the slot 22 on the baffle B21 manually, the volute spring C27 is further compressed, the baffle B21 opens the outlet B2, and the hook 24 is pressed against the wall of the cooling barrel 1 under the restoring action of the volute spring C27 to complete the locking of the baffle B21.

In conclusion, the beneficial effects of the invention are as follows: according to the invention, the traveling path of the edge banding 20 in the cooling liquid is spiral motion, so that the linear traveling distance of the edge banding 20 in the cooling liquid is effectively reduced, the linear length of equipment is reduced, the occupied space of the cooling equipment of the edge banding 20 in a plant is saved, more cooling equipment is conveniently arranged in the plant, the production efficiency of the edge banding 20 is improved, and the production cost of the edge banding 20 is reduced. In addition, the spiral sleeve 4 for providing the cooling channel for the edge sealing strip 20 can axially stretch the part above the middle part of the edge sealing strip 20 when the edge sealing strip 20 is made of a material which is not easy to rapidly cool, so that the screw pitch of the upper half part of the spiral sleeve 4 is increased, the edge sealing strip 20 is not easy to generate large spiral deformation in the process of entering the front half part of the spiral sleeve 4, and the production quality of the edge sealing strip 20 is improved.
