Description

Technical Field

[0001] This invention relates to the field of coating equipment technology, and in particular to a coating device for composite paper that can be adjusted in multiple directions. Background Technology

[0002] The coating equipment, also known as an extrusion laminating machine, extrusion casting machine, or casting laminating machine, typically uses a motor to drive a screw to rotate so that plastic particles are heated and plasticized in the barrel and then extruded in a linear fashion through the coating head die. The plasticized plastic adheres to the surface of paper, and after cooling and shaping, it is pressed into a composite material that combines the barrier and heat-sealing properties of a plastic film layer with the strength and functional characteristics of a substrate.

[0003] Existing laminating equipment typically has a movable adjustment device at the lower end. This allows the laminating head to be moved away from its working position when maintenance is needed on the laminating rollers, cooling rollers, or when switching from double-sided to single-sided lamination. This avoids impacting the laminating equipment. Furthermore, since the laminating head needs to be aligned with the center of the paper surface below, the adjustment device is also required to adjust the laminating position during processing. However, existing laminating equipment often requires high laminating speeds, resulting in high motor power and weight. This causes significant vibration in the motor area during movement and operation, affecting the laminating quality and precision. Summary of the Invention

Detailed Implementation

[0031] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0032] See attached document Figure 1 As shown: In order to allow the coating device to adjust the coating position according to the needs during use, the coating head is usually adjustable in multiple directions, such as forward and backward, left and right, and up and down. Accordingly, this embodiment discloses a multi-directional adjustable coating device for composite paper, including a coating extrusion device 1, a lifting platform 2 for mounting the coating extrusion device 1, and an adjustment platform 3 installed at the lower end of the lifting platform 2 for driving the lifting platform 2 to move in multiple directions. In use, the adjustment platform 3 drives the lifting platform 2 to move in the forward and backward, left and right, and up and down directions, thereby causing the lifting platform 2 to drive the coating extrusion device 1 to adjust and move in the corresponding directions.

[0033] Specifically, such as Figure 1 and Figure 2As shown, the existing coating extrusion device 1 typically includes a barrel 1-1, a feeding screw 1-2 rotatably connected inside the barrel 1-1, a coating head 1-3 located at the discharge end of the barrel 1-1, and a power mechanism 4 located at the feed end of the barrel 1-1 to drive the feeding screw 1-2 to rotate. In use, the coating material is added to the barrel 1-1, which is kept at a certain melting temperature, through a hopper. The power mechanism 4 drives the feeding screw 1-2 to rotate, and then the feeding screw 1-2 conveys the gradually melting coating material in the barrel 1-1 from the feed end to the coating head 1-3 at the discharge end. Finally, the coating head 1-3 coats the outside of the paper sheet moving below.

[0034] When the coating device is moved and adjusted, due to the heavy weight of the power mechanism 4, the power mechanism 4 will generate inertia when it is moved horizontally via the adjustment platform 3. This inertia will cause the installation position of the coating extrusion device 1 to shift during actual use, thus affecting the coating quality and precision of the coating device; specifically, for example... Figure 2 As shown, in this embodiment, the power mechanism 4 includes a reduction gearbox 4-1 that is driven and connected to the tail end of the feeding screw 1-2, and a drive motor 4-2 that is driven and connected to the input shaft of the reduction gearbox 4-1. When the coating device is performing coating, the drive motor 4-2 typically generates vibrations in multiple directions. Therefore, the vibrations generated by the drive motor 4-2 during coating will also affect the coating quality and precision of the coating device. Figure 1 and Figure 2 As shown, to solve the above problems, in this embodiment, a support platform 5 is provided at the lower end of the coating extrusion device 1 and mounted on the lifting platform 2. The support platform 5 includes a buffer platform 5-1 fixedly connected to the lower end of the material cylinder 1-1 and the power mechanism 4. A floating support seat 6 is provided on the lifting platform 2 to support the buffer platform 5-1 and is slidably connected to it relative to the buffer platform 5-1. The buffer platform 5-1 is horizontally floating above the lifting platform 2 via the floating support seat 6. 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 shown... Figure 1 , Figure 4 and Figure 6As shown, the floating support 6 in this embodiment includes a support 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 plate 6-1. The floating support 6 is provided with a base plate 12 corresponding to the universal ball bearing 6-2. A contact plate 13 detachably connected to the base plate 12 and in contact with the ball head of the universal ball bearing 6-2 is provided. In this embodiment, the contact plate 13 is fixedly connected to the base plate 12 by screws. Since the buffer platform 5-1 is supported by the universal bearing 6-2, the contact plate 13 needs to contact the universal bearing 6-2, thus requiring the levelness and roughness of the outer surface of the contact plate 13 to facilitate replacement. Specifically, the adjustment platform 3 in the coating device in this embodiment includes a walking platform 3-1 located at the bottom. The system includes: 1) Ground wheels 3-2 installed around the walking platform 3-1 and driven by a drive mechanism to move the walking platform 3-1 back and forth; 2) Screw jacks 3-3 installed on the walking platform 3-1 to move the lifting platform 2 up and down; and 3-4 translation jacks 3-4 installed on the screw jacks 3-3 to move the lifting platform 2 left and right. Since the adjustment range of the coating device in the left-right and up-down directions in this embodiment is small, and since the center position of the coating head needs to correspond to the center position of the paper below during operation (i.e., when the front and back positions of the coating device are fixed), a certain range of offset of the coating head in the left-right and up-down directions will not significantly affect the coating quality and accuracy of the coating device. Therefore, in this embodiment, shock absorbers 7 are only installed in the front-back movement direction of the coating device.

[0035] Furthermore, such as Figure 12 , Figure 13 and Figure 14As shown, in this embodiment, to avoid dust and debris affecting the normal rolling of the universal ball bearing 6-2, the universal ball bearing in this embodiment has a self-dust-removing structure. Specifically, the universal ball bearing 6-2 in this embodiment includes a base plate 6-2-1 mounted on a support plate 6-1, a support sleeve 6-2-2 disposed on the base plate 6-2-1, and a rolling ball 6-2-4 rollingly disposed within the support sleeve 6-2-2 with its upper end higher than the upper surface of the support sleeve 6-2-2. Specifically, a rotating support cavity 6-2 for mounting the rolling ball 6-2-4 is provided on the inner side of the upper end of the support sleeve 6-2-2. -3. The bottom of the rotating support cavity 6-2-3 is provided with a support limiting spherical surface 27 for supporting and limiting the rolling ball 6-2-4. The support limiting spherical surface 27 surrounds the lower end of the rolling ball 6-2-4 and the upper end of the support limiting spherical surface 27 is in contact with the outer wall of the rolling ball 6-2-4. At the same time, in order to enable the support limiting spherical surface 27 to have a certain limiting effect on the rolling ball 6-2-4 in the horizontal direction, in this embodiment, the distance between the uppermost and lowermost ends of the support limiting spherical surface 27 in the vertical direction is greater than half the radius of the rolling ball 6-2-4 but less than the radius of the rolling ball 6-2-4.

[0036] The upper inner wall of the rotating support cavity 6-2-3 is provided with a spacer blocking surface 28 that surrounds the rolling ball 6-2-4 and is spaced at a certain distance from the rolling ball 6-2-4. Between the spacer blocking surface 28 and the support limiting spherical surface 27, there is a chip-falling cavity 29 that is opened inside the support sleeve 6-2-2 and surrounds the rolling ball 6-2-4. The bottom of the chip-falling cavity 29 is provided with a material-falling surface 30 that gradually slopes downward from the inside to the outside. On the material-falling surface 30, there are several arc-shaped collecting surfaces 31 arranged in a ring around the center of the support sleeve 6-2-2. The arc-shaped collecting surfaces 31 are interconnected and arranged around the rolling ball 6-2-4. The left and right sides of the arc-shaped collecting surfaces 31 gradually decrease towards the center. The support sleeve 6-2-2 has a center position connected to the outer side of the arc-shaped collecting surfaces 31. Discharge port 32; When the universal ball bearing 6-2 rolls, the particles adhering to the outer surface of the rolling ball 6-2-4 rotate together with the rolling ball 6-2-4. Since the interval between the spacer blocking surface 28 and the outer surface of the rolling ball 6-2-4 is constant, larger particles are first intercepted and blocked outside the support sleeve 6-2-2. As the rolling ball 6-2-4 continues to rotate, since the rolling ball 6-2-4 is in close contact with the upper end of the support limiting spherical surface 27, smaller particles are scraped off by the support limiting spherical surface 27 before entering the chip chamber 29. Under the guidance of the arc-shaped collection surface 31, the particles are discharged from the discharge port 32, thereby ensuring the smooth rolling of the universal ball bearing 6-2 and extending the service life of the universal ball bearing 6-2.

[0037] The buffer platform 5-1 is located at the lower end of the material cylinder 1-1 and extends downwards towards the power mechanism 4. An auxiliary support platform 8 extending towards the material cylinder 1-1 is provided on the side of the buffer platform 5-1 away from the power mechanism 4. A support frame 9, which supports the outer side of the material cylinder 1-1, is fixedly connected to the auxiliary support platform 8. Specifically, as shown... Figure 1 , Figure 4 and Figure 6 As shown, in this embodiment, there are two pairs of floating support seats 6. One pair of floating support seats 6 is installed on the lifting platform 2 below the reduction gearbox 4-1, and the other pair of floating support seats 6 is installed on the lifting platform 2 below the auxiliary support platform 8. This allows the floating support seats 6 to be supported on the outer surface of the buffer platform 5-1 below the auxiliary support platform 8 and the power mechanism 4. In this embodiment, the shock absorber 7 is installed at the lower end of the drive 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 or coating work is required, the power mechanism 4 tends to move the buffer platform 5-1 under inertia or during operation. At this time, since the lower end of the buffer platform 5-1 is connected to the lifting platform 2 by the shock absorber 7, the shock absorber 7 can eliminate the inertia in the corresponding direction of the buffer platform 5-1 or the vibration in the corresponding direction generated by the power mechanism 4 during operation, thereby avoiding the impact on the coating quality and coating accuracy of the coating device.

[0038] Going a step further, such as Figure 4 , Figure 6 and Figure 9 As shown, when the coating device is assembled or when the shock absorber 7 needs to be disassembled for maintenance, in order to prevent the buffer platform 5-1 from moving arbitrarily, a flexible contact part 14 extending vertically downward is fixedly connected to the lower end face of the buffer platform 5-1 in this embodiment. A rigid limiting part 15 is provided on the outer side of the lower end of the flexible contact part 14, surrounding the flexible contact part 14 and installed on the lifting platform 2. The buffer platform 5-1 is limited in the horizontal movement direction by the flexible contact part 14. When the flexible contact part 14 moves, it contacts and limits the movement with the rigid limiting part 15. Thus, 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, preventing the buffer platform 5-1 from falling off the lifting platform 2. This keeps the coating device within a certain range of assembly or installation positions, which facilitates the subsequent reinstallation of the shock absorber 7 or other components.

[0039] Furthermore, such as Figure 7 and Figure 8As shown, in this embodiment, the lifting platform 2 is equipped with a mold head fixing frame 16 for auxiliary fixing of the coating head 1-3. The mold head fixing frame 16 includes connecting arms 16-1 located on the left and right sides of the material cylinder 1-1, support arms 16-2 located at the front end of the connecting arms 16-1 and extending to the upper end of the coating head 1-3, connecting arms 16-3 located between the left and right support arms 16-2, positioning members 16-4 connected between the connecting arms 16-3 and the coating head 1-3, and fixing feet 16-5 located on the connecting arms 16-3 and extending to the lifting platform 2. The mold head fixing frame 16 is fixed on the lifting platform 2 to stably position the coating head 1-3, thereby ensuring that the coating head 1-3 is accurately positioned during operation and ensuring coating quality.

[0040] Furthermore, such as Figure 11 As shown, in this embodiment, in order to facilitate the smooth movement of the lifting platform 2, a lifting beam 20 is provided on the screw drive end above the screw jack 3-3, located on the front and rear sides below the lifting platform 2 and perpendicular to the moving direction of the traveling platform 3-1. A translation slider 21 is provided on the lifting beam 20, and a translation guide rail 22 installed on the lifting platform 2 is slidably connected to the upper end of the translation slider 21. A translation support seat 23 extending inward is installed on the lifting beam 20. The translation support seat 23 is connected to the screw drive end of the translation jack 3-4. The translation jack 3-4 is fixedly connected to the lower plane of the lifting platform 2.

[0041] Furthermore, such as Figure 6 and Figure 10As shown, to facilitate the installation of the flexible contact part 14 and ensure that the flexible contact part 14 can be effectively confined within the rigid confining part 15 to prevent the flexible contact part 14 from coming out of the rigid confining part 15, in this embodiment, an installation adjustment hole 17 is provided at the center of the inner side of the flexible contact part 14, facing the rigid confining part 15. A positioning center rod 18 is fixedly connected to the lower end of the buffer platform 5-1 at the center of the inner side of the installation adjustment hole 17. The bottom of the installation adjustment hole 17 is provided with an installation hole 24 that is opened on the flexible contact part 14 and communicates with the buffer platform 5-1. The upper end of the positioning center rod 18 passes through the installation hole 24 and is threadedly connected to a locking screw 19 that passes through the buffer platform 5-1 from top to bottom. A horizontally extending extrusion space is provided on the installation adjustment hole 17. 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. An outer expansion portion 26 is connected within the extrusion space. The outer expansion portion 26 and the positioning center rod 18 are integrally formed. In this embodiment, the outer side of the outer expansion portion 26 contacts the inner wall of the extrusion space. The upper end of the outer 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 is driven by rotating the locking screw 19 to move the outer expansion portion 26 upward, thereby clamping and fixing the extrusion mounting surface 25 and the flexible contact portion 14 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 contacts the rigid limiting portion 15. At the same time, the flexible contact portion 14 and the outer expansion portion 26 effectively support the flexible contact portion 14, preventing the flexible contact portion 14 from deforming excessively and coming out of the rigid limiting portion 15.
