Technical Field

[0001] The invention relates to the technical field of extruder traction, in particular to a traction device for traction of a corner foam board. Background Art

[0002] Extrusion, also known as extrusion, is a plastic molding process and one of the important methods for thermoplastic molding. The plastic raw material is heated to make it viscous and flow, and under the action of pressure, it passes through the extrusion die to become a continuum with a cross-section similar to the shape of the die, and then cooled and shaped.

[0003] The commonly used cooling method is water cooling through a water tank. The device used for traction is a set of conveyor belts set at the rear end of the water tank. The conveyor belts are divided into two groups, the upper and lower conveyor belts. The cooled sheet is clamped between the upper and lower conveyor belts, and the conveyor belts provide traction power for the extruded sheet.

[0004] However, the current traction device can often only adjust the distance between the upper and lower conveyor belts, that is, it can only pull flat plates. When the plates manufactured by the extruder are replaced with right-angled corner plates, for example, the conventional traction device cannot pull them, resulting in the production of only a single type of plate, which has production limitations.

DETAILED DESCRIPTION

[0026] The embodiment of the present invention provides a traction device for traction of a corner foam board, such as Figure 1-6 As shown, it is arranged after the extruder, the shaping die table, and the cooling water tank. The extruder, the shaping die table, and the cooling water tank are prior arts and will not be described in detail. The traction device includes two sets of symmetrical conveyor belts, the conveyor belt includes a support plate 4, at least two sprockets 2, and a chain 3 meshed outside the two sprockets 2. The support plate 4 is fixed to the ground through a fixed bracket. The sprocket 2 is rotatably arranged on the support plate 4, and the chain 3 is meshed outside the sprocket 2 to form an annular conveying structure. A driving motor for driving the sprocket 2 is arranged on the support plate 4, and the driving motor is used to provide power to the sprocket 2.

[0027] The innovation of the present application is to improve the tractor 1 on the chain 3. The traditional tractor 1 is a fixed flat plate or a template customized according to the plate.

[0028] like Figure 1 As shown, traction devices 1 are arranged at equal intervals on the chain 3. The traction devices 1 include a connecting block 11, two rotating arms 14, and an adjusting component. The connecting block 11 is arranged on the chain 3, the two rotating arms 14 are arranged symmetrically, and the adjusting component is arranged on the chain 3 and is used to adjust the angles of the two rotating arms 14.

[0029] Specifically, Figure 3As shown, the adjustment assembly includes a fixed frame 12, a movable frame 13, two arc-shaped connecting rods 15, a spring 16, a slide rail 17, and a slider 18 slidably adapted on the slide rail 17. The slide rail 17 is vertically arranged on the fixed frame 12, and the upper end is connected to the connecting block 11. The slide rail 17 serves as a support point of the fixed frame 12. The movable frame 13 is connected to the slider 18, and the movable frame 13 can slide vertically along the length direction of the slide rail 17. The cross section of the fixed frame 12 is concave, and an L-shaped notch is arranged at one corner of the rotating arm 14. The rotating arm 14 is hinged to the fixed frame 12 at the lower end face of the L-shaped notch, and is hinged to the movable frame 13 at the side end face of the L-shaped notch through the arc-shaped connecting rod 15. The arc-shaped connecting rod 15 is arc-shaped, and the rotating arm 14 and the fixed frame 12 and the two hinge points of the arc-shaped connecting rod 15 are arranged in an L-shaped orientation. The spring 16 is arranged between the fixed frame 12 and the movable frame 13.

[0030] When the slider 18 connected to the movable frame 13 is in the position as shown in FIG. Figure 3 When the slide rail 17 is at the top limit position shown, the bottom surfaces of the two rotating arms 14 are parallel planes. When the movable frame 13 slides downward, the rotating arms 14 are driven to change angles through the arc-shaped connecting rod 15, and the angles can be customized as desired, such as Figure 6 As shown, the bottom surfaces of the two rotating arms 14 form an angle of 90°.

[0031] The bottom surface of the rotating arm 14 is provided with a template 19. The template 19 is used for contacting the profile, and the template 19 is made of metal or ceramic.

[0032] By setting an adjustment component to adjust the angle between the two rotating arms 14, adjustments can be made according to the flat profile, right-angle wall corner plate or other angle bent profile types required by the customer. There is no need to replace the traction device when switching the profile type. The production versatility is strong and the replacement cost of the traction device is saved.

[0033] The traction device also includes two guide bars 6, which extend along the length direction of the lower half of the upper chain 3 and the upper half of the lower chain 3 respectively, and the overall length of the guide bar 6 is half of the chain 3. The two ends of the guide bar 6 extend along the arc directions on both sides of the chain 3. A guide slope 7 is provided on the side of the guide bar 6 facing the conveying direction of the chain 3, and a guide block 8 is provided on each movable frame 13. The side of the guide block 8 corresponding to the guide slope 7 is a force-bearing slope 9 tangent thereto. When the force-bearing slope 9 of the guide block 8 contacts the guide slope 7 of the guide bar 6, the guide block 8 will be displaced by force, thereby adjusting the height of the movable frame 13.

[0034] The height of the guide bar 6 can be adjusted according to the angle requirement of the rotating arm 14. When the guide block 8 passes through the guide bar 6 without contact, as shown in FIG. Figure 1As shown, the bottom surfaces of the two rotating arms 14 are parallel planes. When the distance between the guide bar 6 and the plane height of the sprocket 2 increases, the guide block 8 will contact the guide bar 6 when passing through the guide bar 6, and the guide block 8 will be displaced by force and move along the lower edge of the guide bar 6.

[0035] In order to synchronize the displacement of the upper and lower guide bars 6 and the two sets of conveyor belts, the traction device also includes two sets of spacing adjustment mechanisms 5, which are used to adjust the spacing between the two support plates 4 and the two guide bars 6 respectively.

[0036] The specific spacing adjustment mechanism 5 includes a bracket 51, a screw 52, ​​a motor 54, a slide rod 55, two nuts 53, and two sliding sleeves 56. The slide rod 55 is vertically arranged on the bracket 51. The upper and lower ends of the screw 52 are pivotally connected to the bracket 51 through a bearing seat. The two sliding sleeves 56 are slidably sleeved on the slide rod 55 and are respectively connected to two guide bars 6. The upper and lower sections of the screw 52 have opposite thread rotation directions. The two nuts 53 are threadedly sleeved on the two opposite sections of the screw 52 and are respectively connected to the two guide bars 6. The motor 54 is arranged on the bracket 51, and the output end is coaxially connected to the screw 52.

[0037] The nut 53 and the sliding sleeve 56 in the spacing adjustment mechanism 5 connecting the conveyor belt are connected to the support plate 4 .

[0038] By providing the lead screw 52 with upper and lower sections of threads rotating in opposite directions, when the lead screw 52 rotates, the guide bar 6 or the support plate 4 connecting the two nuts 53 will move in opposite directions, thereby achieving synchronous displacement.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
