Description

Technical Field

[0001] The invention relates to the technical field of laminating equipment, and in particular to a laminating device for composite paper which can be adjusted in multiple directions. Background Art

[0002] The laminating device is also called extrusion compounding machine, extrusion casting machine, casting compounding machine, etc. It usually drives the screw to rotate through a motor so that the plastic particles are heated and plasticized by the barrel and then extruded in a linear shape from the die of the laminating head. The plasticized plastic adheres to the surface of the paper, is cooled and shaped, and pressed into a composite material that has the barrier and heat sealing properties of the plastic film layer and the strength and functional characteristics of the substrate.

[0003] The existing laminating device is usually provided with a movable adjustment device at the lower end, so that when it is necessary to repair the laminating roller, cooling roller, etc. at the lower end of the laminating head or to change the double-sided lamination into single-sided lamination, the laminating head can be moved away from the working position by the movable adjustment device to avoid affecting the laminating device. At the same time, since the center position of the laminating head needs to be aligned with the center position of the paper surface below when the laminating head is working, the movable adjustment device is also required to adjust the laminating position of the laminating head during processing and lamination; and the existing laminating device usually requires a higher laminating speed, which makes the corresponding motor power larger and the weight of the motor heavier when in use.

DETAILED DESCRIPTION

[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0019] See attached Figure 1 As shown: In order to enable the laminating device to adjust the laminating position according to needs during use, the laminating head is usually allowed to be adjusted in multiple directions such as front and back, left and right, and up and down. Correspondingly, this embodiment discloses a multi-directionally adjustable laminating device for composite paper, including a laminating extrusion device 1, a lifting platform 2 for installing the laminating extrusion device 1, and an adjusting platform 3 installed at the lower end of the lifting platform 2 for driving the lifting platform 2 to move in multiple directions; when in use, the adjusting platform 3 drives the lifting platform 2 to move in the front and back, left and right, and up and down directions, thereby allowing the lifting platform 2 to drive the laminating extrusion device 1 to adjust and move in the corresponding directions.

[0020] Specifically, Figure 1 and Figure 2 As shown, the existing coating extrusion device 1 usually includes a barrel 1-1, a feeding screw 1-2 rotatably connected to the barrel 1-1, a coating head 1-3 arranged at the discharge end of the barrel 1-1, and a power mechanism 4 arranged at the feed end of the barrel 1-1 to drive the feeding screw 1-2 to rotate. When in use, the coating raw material is added into the barrel 1-1 maintained at a certain melting temperature through the hopper, and the power mechanism 4 drives the feeding screw 1-2 to rotate, and then the coating raw material gradually melted in the barrel 1-1 is transported from the feed end to the coating head 1-3 at the discharge end through the feeding screw 1-2, and finally the outer side of the paper sheet moving below is coated by the coating head 1-3.

[0021] When the laminating device is moved and adjusted, due to the heavy weight of some positions of the power mechanism 4, when the horizontal adjustment is performed through the adjustment platform 3, the power mechanism 4 will generate corresponding inertia, and accordingly, the installation position of the laminating extrusion device 1 will be relatively offset in actual use due to the inertia generated during the adjustment movement, thereby affecting the laminating quality and laminating accuracy of the laminating device; specifically, Figure 2 As shown, in this embodiment, the power mechanism 4 includes a reduction box 4-1 drivingly connected to the tail end of the feeding screw 1-2 and a drive motor 4-2 drivingly connected to the input shaft of the reduction box 4-1; when the laminating device is laminating, the drive motor 4-2 usually generates vibrations in multiple directions, and thus, when laminating, the vibrations generated by the drive motor 4-2 will also correspondingly affect the laminating quality and laminating accuracy of the laminating device; Figure 1 and Figure 2As shown, in order to solve the above problems, in this embodiment, a supporting platform 5 arranged on the lifting platform 2 is provided at the lower end of the laminating extrusion device 1, and the supporting platform 5 includes a buffer platform 5-1 fixedly connected to the barrel 1-1 and the lower end of the power mechanism 4, and a floating support seat 6 for supporting the buffer platform 5-1 and slidingly connected relative to the buffer platform 5-1 is provided on the lifting platform 2. The buffer platform 5-1 is horizontally floated above the lifting platform 2 through the floating support seat 6, and a shock absorber 7 is provided between the buffer platform 5-1 and the lifting platform 2 along the moving direction of the lifting platform 2. Specifically, as Figure 1 , Figure 4 and Figure 6 As shown, the floating support seat 6 in this embodiment includes a support seat plate 6-1 fixedly connected to the upper end of the lifting platform 2 and a universal ball bearing 6-2 detachably connected to the support seat plate 6-1, and a base plate 12 corresponding to the universal ball bearing 6-2 is provided on the floating support seat 6, and a contact plate 13 detachably connected to the base plate 12 is provided to contact the ball head of the universal ball bearing 6-2; wherein, the contact plate 13 in this embodiment is fixedly connected to the base plate 12 by screws, and since the buffer platform 5-1 is supported by the universal bearing 6-2, wherein the contact plate 13 needs to contact the universal bearing 6-2, and thus the horizontality and roughness of the outer surface of the contact plate 13 need to be ensured, so that the contact plate 13 is easy to replace; specifically, the adjustment platform 3 in the coating device in this embodiment includes a walking platform 3-1 located at the bottom , ground wheels 3-2 arranged around the walking platform 3-1 and driven by a driving mechanism to drive the walking platform 3-1 to move forward and backward, a screw elevator 3-3 arranged on the walking platform 3-1 for driving the lifting platform 2 to move up and down, and a translation elevator 3-4 arranged on the screw elevator 3-3 for driving the lifting platform 2 to move left and right; among them, since the adjustment range of the laminating device in the left and right and up and down directions in this embodiment is small, and since the center position of the laminating head needs to correspond to the center position of the paper below when working (that is, when the front and back positions of the laminating device are fixed), the laminating head is offset within a certain range in the left and right and up and down directions and will not have a significant impact on the laminating quality and laminating accuracy of the laminating device. Therefore, in this embodiment, the shock absorber 7 is only arranged in the front and back moving direction of the laminating device.

[0022] Furthermore, if Fig.12 , Fig.13 and Fig.14As shown, in order to prevent dust and debris from affecting the normal rolling of the universal ball bearing 6-2, the universal ball bearing in this embodiment is a self-dust removal structure. Specifically, the universal ball bearing 6-2 in this embodiment includes a base plate 6-2-1 installed on the support base plate 6-1, a support sleeve 6-2-2 set on the base plate 6-2-1, and a rolling ball 6-2-4 rollingly set in the support sleeve 6-2-2 and with the upper end higher than the upper end surface of the support sleeve 6-2-2; Specifically, a rotating support cavity 6-2-4 for mounting the rolling ball 6-2-4 is opened on the inner side of the upper end of the support sleeve 6-2-2. -3, a supporting and limiting spherical surface 27 for supporting and limiting the rolling ball 6-2-4 is arranged at the bottom of the rotating support cavity 6-2-3, the supporting and limiting spherical surface 27 surrounds the lower end of the rolling ball 6-2-4 and the upper end of the supporting and limiting spherical surface 27 is in contact with and fits with the outer wall of the rolling ball 6-2-4. At the same time, in order to make the supporting and limiting spherical surface 27 have a certain limiting effect on the rolling ball 6-2-4 in the horizontal direction, in this embodiment, the distance between the uppermost end and the lowermost end of the supporting and limiting spherical surface 27 in the vertical direction is set to be greater than half of the radius of the rolling ball 6-2-4 and less than the radius of the rolling ball 6-2-4.

[0023] The inner wall of the upper end of the rotating support cavity 6-2-3 is provided with a spacing blocking surface 28 which surrounds the rolling ball 6-2-4 and is arranged at a certain distance from the rolling ball 6-2-4. A chip dropping cavity 29 is provided between the spacing blocking surface 28 and the supporting limiting spherical surface 27, which is opened inside the supporting sleeve 6-2-2 and is arranged around the rolling ball 6-2-4. The bottom of the chip dropping cavity 29 is provided with a dropping surface 30 which gradually tilts downward from the inside to the outside. The dropping surface 30 is provided with a plurality of arc-shaped collecting surfaces 31 which are arranged in a circular array with the center of the supporting sleeve 6-2-2 as the center. The plurality of arc-shaped collecting surfaces 31 are connected to each other and are arranged around the rolling ball 6-2-4. The left and right sides of the arc-shaped collecting surfaces 31 are gradually lowered toward the center position. The supporting sleeve 6-2-2 is provided with a connecting rod 30 which is connected to the outer center position of the arc-shaped collecting surface 31. Discharge port 32; when the universal ball bearing 6-2 rolls, the particles adhered to the outer surface of the rolling ball 6-2-4 rotate with the rolling ball 6-2-4, wherein, due to the certain interval between the spacing blocking surface 28 and the outer surface of the rolling ball 6-2-4, the larger particles are first intercepted and blocked on the outside of the supporting sleeve 6-2-2, and in the process of the rolling ball 6-2-4 continuing to rotate, since the rolling ball 6-2-4 is fitted with the upper end of the supporting and limiting spherical surface 27, the smaller particles are scraped off by the supporting and limiting spherical surface 27 before entering the supporting and limiting spherical surface 27 and fall into the chip removal chamber 29, so that the particles are discharged from the discharge port 32 under the guidance of the arc-shaped collecting surface 31, thereby ensuring the smooth rolling of the universal ball bearing 6-2 and extending the service life of the universal ball bearing 6-2.

[0024] The buffer platform 5-1 is located at the lower end of the barrel 1-1 and extends below the power mechanism 4. An auxiliary support platform 8 extending toward the barrel 1-1 is provided on the side of the buffer platform 5-1 away from the power mechanism 4. A support frame 9 supported and arranged outside the barrel 1-1 is fixedly connected to the auxiliary support platform 8. Specifically, Figure 1 , Figure 4 and Figure 6 As shown, in the present embodiment, two pairs of floating support seats 6 are arranged, one pair of floating support seats 6 is installed on the lifting platform 2 below the reduction box 4-1, and the other pair of floating support seats 6 is installed on the lifting platform 2 below the auxiliary support platform 8, so that the floating support seats 6 are supported on the outer surface of the buffer platform 5-1 arranged below the auxiliary support platform 8 and the power mechanism 4; wherein, the shock absorber 7 in the present embodiment is arranged at the lower end of the driving motor 4-2, the tail end of the shock absorber 7 is rotatably connected to the tail seat 10 fixed on the lifting platform 2, and the piston end of the shock absorber 7 is rotatably connected to the shock absorber mounting seat 11 fixed on the buffer platform 5-1; when adjustment movement or lamination work is required, the power mechanism 4 has a tendency to drive the buffer platform 5-1 to move under the action of inertia or when working. At this time, since the shock absorber 7 is connected between the lower end of the buffer platform 5-1 and the lifting platform 2, the inertia of the buffer platform 5-1 in the corresponding direction or the vibration in the corresponding direction generated when the power mechanism 4 is working is eliminated by the shock absorber 7, thereby avoiding the lamination quality and lamination accuracy of the lamination device.

[0025] Further, such as Figure 4 , Figure 6 and Fig. 9 As shown, when the laminating device is assembled or when the laminating device needs to be maintained and repaired and the shock absorber 7 is disassembled, in order to avoid the random movement of the buffer platform 5-1, a flexible contact portion 14 extending vertically downward is fixedly connected to the lower end surface of the buffer platform 5-1 in this embodiment, and a hard limiting portion 15 surrounding the flexible contact portion 14 and installed on the lifting platform 2 is provided on the outer side of the lower end of the flexible contact portion 14. The buffer platform 5-1 is limited in the moving direction of the horizontal plane by the flexible contact portion 14. When the flexible contact portion 14 moves, it contacts and limits the hard limiting portion 15, so that after the shock absorber 7 is disassembled, the movement of the buffer platform 5-1 relative to the lifting platform 2 is within a certain range, avoiding the buffer platform 5-1 from being separated from the lifting platform 2, and then the laminating device is located within a certain range of assembly or installation positions, so as to facilitate the subsequent reinstallation of the shock absorber 7 or other components.

[0026] Further, such as Figure 7 and Figure 8As shown, the lifting platform 2 in this embodiment is equipped with a die head fixing frame 16 for auxiliary fixing of the laminating head 1-3. The die head fixing frame 16 includes a connecting arm 16-1 located on the left and right sides of the barrel 1-1, a support arm 16-2 arranged at the front end of the connecting arm 16-1 and extending toward the upper end of the laminating head 1-3, a connecting arm 16-3 arranged between the left and right support arms 16-2, a positioning member 16-4 connected between the connecting arm 16-3 and the laminating head 1-3, and a fixed foot 16-5 arranged on the connecting arm 16-3 and extending toward the lifting platform 2. A die head fixing frame 16 fixed on the lifting platform 2 is provided, and the laminating head 1-3 is firmly positioned by the die head fixing frame 16, thereby ensuring that the laminating head 1-3 is accurately positioned during operation and the laminating quality is guaranteed.

[0027] Furthermore, if Fig.11 As shown, in order to facilitate the smooth movement of the lifting platform 2, a lifting beam 20 is provided on the screw driving end above the screw elevator 3-3, which is located on the front and rear sides below the lifting platform 2 and is arranged perpendicular to the moving direction of the walking platform 3-1. A translation slider 21 is provided on the lifting beam 20, and the upper end of the translation slider 21 is slidably connected to a translation guide rail 22 installed on the lifting platform 2. A translation support seat 23 extending inward is installed on the lifting beam 20, and the translation support seat 23 is connected to the screw driving end on the translation elevator 3-4.

[0028] Furthermore, if Figure 6 and Fig.10As shown, in order to facilitate the installation of the flexible contact part 14 and ensure that the flexible contact part 14 can be effectively limited in the hard limiting part 15 to prevent the flexible contact part 14 from escaping from the hard limiting part 15, an installation adjustment hole 17 arranged toward the hard limiting part 15 is opened at the inner center position of the flexible contact part 14 in this embodiment, and a positioning center rod 18 fixedly connected to the lower end of the buffer platform 5-1 is provided at the inner center position of the installation adjustment hole 17. A mounting hole 24 opened on the flexible contact part 14 and connected to the buffer platform 5-1 is provided at the bottom of the installation adjustment hole 17. After the upper end of the positioning center rod 18 passes through the mounting hole 24, it is threadedly connected with a locking screw 19 that passes through the buffer platform 5-1 from top to bottom. A horizontally outwardly extending extrusion space is opened on the installation adjustment hole 17, and an extrusion mounting surface 25 is provided at the bottom of the extrusion space. The outer side of the positioning center rod 18 is fixed It is connected to an outward expansion portion 26 located in the extrusion space, wherein the outward expansion portion 26 and the positioning center rod 18 are integrally arranged, and the outer side of the outward expansion portion 26 in this embodiment is arranged in contact with the inner wall of the extrusion space, and the upper end of the outward expansion portion 26 is in extrusion contact with the extrusion mounting surface 25 and the flexible contact portion 14 is fixed to the lower end of the buffer platform 5-1 through the extrusion mounting surface 25; during installation, the positioning center rod 18 drives the outward expansion portion 26 to move upward by rotating the locking screw 19, so that the extrusion mounting surface 25 and the flexible contact portion 14 are clamped and fixed to the lower end of the buffer platform 5-1; when the shock absorber 7 is not installed for assembly or maintenance, the outer flexible contact portion 14 is in contact with the hard limiting portion 15, and at the same time, the flexible contact portion 14 is effectively supported by the flexible contact portion 14 and the outward expansion portion 26 to prevent the flexible contact portion 14 from being excessively deformed and escaping from the hard limiting portion 15.
