Description

Technical Field

[0001] This invention relates to the field of gypsum board forming equipment, and more specifically to a shaping device for paper-faced gypsum board. Background Technology

[0002] Plaster slurry is poured into the three-dimensional rectangular cavity formed by folding the facing paper. After the plaster slurry dries and solidifies, it forms a plasterboard. Before the plaster slurry solidifies, it flows disorderly inside the facing paper, causing the surface of the facing paper to be uneven. At the same time, the facing paper will also deform due to moisture. Therefore, it is necessary to shape it before the plasterboard solidifies.

[0003] Typically, existing technology involves using a flat plate to press the top surface of the wet gypsum board from top to bottom during the transportation of wet gypsum board on a forming belt, forcing the top and bottom walls of the wet gypsum board to become flat during the pressing process.

[0004] The flat plate is usually made of glass. The operator wraps the two ends of the glass plate with cardboard or towel, and then fixes the two ends of the glass plate to the support with clamps, so that the glass plate is suspended horizontally above the forming belt. In this way, when the wet gypsum board passes under the glass plate, both sides of the wet gypsum board are squeezed by the forming belt and the glass plate, thus tending to be flat.

[0005] However, the process of installing and adjusting the glass plate is very complicated. Operators need to rely on their own experience to repeatedly adjust the height and angle of both ends of the glass plate so that the glass plate is parallel to the forming belt and the distance between the glass plate and the forming belt is equal to the thickness of the gypsum board. The manual adjustment process is prone to deviation, and the glass plate lacks suitable clamps, which can easily loosen during use, thus affecting the surface flatness of the gypsum board. Summary of the Invention

[0006] The purpose of this invention is to provide a shaping device for paper-faced gypsum board, so as to solve the problem that the installation and adjustment process of the glass plate used to level the surface of the gypsum board depends on the operator's experience, and the parallelism and distance between the glass plate and the forming belt are difficult to control.

[0007] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0008] A shaping device for paper-faced gypsum board includes: a lifting device, a crossbeam, a first glass plate, a second glass plate, and a level; the lifting device is fixedly connected to a frame, the actuator of the lifting device is connected to both ends of the crossbeam, the crossbeam is horizontally suspended directly above a forming belt, and both ends of the crossbeam are located on both sides of the forming belt; the first glass plate and the second glass plate are respectively pasted to the top and bottom of the crossbeam, and the top wall of the first glass plate and the bottom wall of the second glass plate are parallel to each other; the crossbeam is made of metal material, and the level is installed on the top of the first glass plate.

[0009] Furthermore, the level is a bubble level, which is installed at both ends and the middle of the first glass plate. The bubble movement direction of the bubble level located at both ends of the first glass plate is parallel to the length direction of the crossbeam, and the bubble movement direction of the bubble level located in the middle of the first glass plate is perpendicular to the length direction of the crossbeam.

[0010] Furthermore, the lifting device includes two lead screw slides and two cylinders disposed on both sides of the forming belt. The lead screw slides are vertically arranged and fixedly connected to the frame. Each cylinder is vertically arranged and fixedly connected to the actuator of one lead screw slide. The two ends of the crossbeam are respectively connected to the actuators of the two cylinders.

[0011] Furthermore, the shaping device also includes a rotary driver and a bearing housing; the rotary driver and the bearing housing are located on both sides of the forming belt 2, and both are connected to a rotating shaft. The two rotating shafts are coaxially arranged and connected to both ends of the crossbeam 4. The rotary driver and the bearing housing are both connected to the actuator of the lifting device, so that the crossbeam can be raised and lowered and rotated around its own center line.

[0012] Furthermore, the rotary drive includes a servo motor and a right-angle reducer. The servo motor is fixedly connected to the actuator of the lifting device, and the servo motor is driven by the right-angle reducer to the rotating shaft.

[0013] Furthermore, at least one of the aforementioned shafts is connected to a brake.

[0014] Furthermore, the crossbeam includes a square tube, and the square tube is made of stainless steel.

[0016] Furthermore, the profile has multiple through holes formed inside it along its length. The two ends of the through holes are connected to a constant temperature water circulation system. The constant temperature water circulation system is used to circulate a constant temperature liquid inside the through holes so that the temperature of the crossbeam, the first glass plate and the second glass plate remains constant.

[0017] Furthermore, the two clamps respectively cover the through holes at both ends of the profile, and a sealing ring is provided between the clamps and the profile; one of the clamps is provided with an inlet and an outlet respectively connecting the two through holes, and the other clamp is provided with a water channel respectively connecting the two through holes, and the sealing ring is used to seal the gaps between the through hole and the inlet, the through hole and the outlet, and the through hole and the water channel.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] The following describes a shaping device for paper-faced gypsum board.

[0033] Example 1, please refer to Figure 1 , 2 3.

[0034] The shaping device includes: a lifting device 3, a crossbeam 4, a first glass plate 5, a second glass plate 6, and a level.

[0035] The lifting device 3 is fixedly connected to the frame 1. The actuator of the lifting device 3 is connected to both ends of the crossbeam 4. The crossbeam 4 is horizontally suspended directly above the forming belt 2, and both ends of the crossbeam 4 are located on both sides of the forming belt 2.

[0036] The first glass plate 5 and the second glass plate 6 are respectively attached to the top and bottom of the crossbeam 4, and the top wall of the first glass plate 5 and the bottom wall of the second glass plate 6 are parallel to each other. The crossbeam 4 is made of metal material, and the level is installed on the top of the first glass plate 5.

[0037] The lifting device 3 is used to adjust the height of both ends of the crossbeam 4, and the level is used to measure the levelness of the first glass plate 5. Since the first glass plate 5 and the second glass plate 6 are parallel to each other, when the level shows that the first glass plate 5 is level, the second glass plate 6 is also level.

[0038] Preferably, the crossbeam 4 includes a square tube 42, which is made of stainless steel and is manufactured by a drawing process. It has good straightness and bending strength, and its surface is flat, making it easy to attach glass plates.

[0039] In Example 1, when the flatness of the top wall of the crossbeam 4 is close to that of the glass surface, only the second glass plate 6 can be used instead of the first glass plate 5. However, the crossbeam 4 is usually made of existing metal profiles, such as the square tube 42 mentioned above. It is difficult and costly to process the surface of the square tube 42 to be close to that of the glass surface. Therefore, Example 1 adopts a simpler method, directly pasting the first glass plate 5 and the second glass plate 6 onto the top and bottom walls of the square tube 42. During the pasting process, an excess of glass glue is applied to both sides of the square tube 42. A custom mold is used to push the first glass plate 5 and the second glass plate 6 onto both sides of the square tube 42. The parallelism of the first glass plate 5 and the second glass plate 6 is measured by a measuring instrument. When the first glass plate 5 and the second glass plate 6 are parallel to each other, the excess glass glue is squeezed out. After the glass glue solidifies, the overflowing glass glue is cut off to obtain two parallel surfaces.

[0040] The level is a bubble level 51, which is installed at both ends and in the middle of the first glass plate 5. The bubble movement direction of the bubble level 51 located at both ends of the first glass plate 5 is parallel to the length direction of the crossbeam 4, and the bubble movement direction of the bubble level 51 located in the middle of the first glass plate 5 is perpendicular to the length direction of the crossbeam 4.

[0041] Furthermore, the connection between the actuator of the lifting device 3 and the crossbeam 4 may wear out after long-term use. In this case, simply adjusting the height of both ends of the crossbeam 4 is insufficient to adjust the crossbeam 4 to a completely horizontal state. To solve this problem, a preferred embodiment is provided below.

[0042] The shaping device also includes: a rotary drive 7 and a bearing housing 8;

[0043] The rotary drive 7 and the bearing housing 8 are located on both sides of the forming belt 2, and both are connected to a rotating shaft 41. The two rotating shafts 41 are coaxially arranged and connected to both ends of the crossbeam 4. The rotary drive 7 and the bearing housing 8 are both connected to the actuator of the lifting device 3 so that the crossbeam 4 can be raised, lowered and rotated around its own center line.

[0044] The rotary drive 7 includes a servo motor 71 and a right-angle reducer 72. At least one rotating shaft 41 is connected to a brake (not shown in the figure). The servo motor 71 is used to fine-tune the angle of the crossbeam 4. After the operator has finished adjusting, the brake brakes the rotating shaft 41 so that the crossbeam 4 cannot rotate.

[0045] Furthermore, in order to facilitate the operator to adjust the crossbeam 4 to a completely horizontal state, the crossbeam 4 also needs to be able to change the degree of freedom of its two ends. A preferred embodiment is provided below.

[0046] The lifting device 3 includes two lead screw slides 31 and two cylinders 32 arranged on both sides of the forming belt 2. The lead screw slides 31 are vertically arranged and fixedly connected to the frame 1. Each cylinder 32 is vertically arranged and fixedly connected to the actuator of one lead screw slide 31.

[0047] Among them, the lead screw slide 31 is used to finely adjust the height of both ends of the crossbeam 4, and the cylinder 32 is used to raise and lower the crossbeam 4 during the production process, so that the second glass plate 6 is raised to avoid the head of the gypsum board or lowered to squeeze the top wall of the gypsum board.

[0048] Normally, a clamp 45 should be used to connect the square tube 42 and the actuator of the cylinder 32. However, the square tube 42 is easily deformed by clamping, which can lead to the glass plate shattering. At the same time, due to the different degrees of thermal expansion and contraction between stainless steel and glass, the glue between the square tube 42 and the glass plate is prone to cracking in usage scenarios with large temperature changes, affecting the parallelism between the first glass plate 5 and the second glass plate 6.

[0049] To address the aforementioned issues, a preferred embodiment is provided below.

[0050] Example 2, please refer to Figure 4 , 5 6, 7, 8.

[0051] The crossbeam 4 includes a square tube 42 and a profile 43. The profile 43 is inserted inside the square tube 42 and is interference-fitted with the square tube 42. Both ends of the profile 43 extend to the outside of the square tube 42. Clamps 45 are installed at both ends of the profile 43. The clamps 45 and the rotating shaft 41 are an integral piece.

[0052] Profile 43 is made of aluminum alloy, which has good bending, torsion and compressive strength, and can bear the clamping force of clamp 45 while maintaining its shape.

[0053] The profile 43 has multiple through holes 44 formed inside it along the length of the profile 43. The two ends of the through holes 44 are connected to a constant temperature water circulation system. The constant temperature water circulation system is used to circulate a constant temperature liquid inside the through holes 44 so that the temperature of the crossbeam 4, the first glass plate 5 and the second glass plate 6 remains constant.

[0054] Typically, aluminum alloy profiles naturally have four through holes 44, meaning there are a total of 8 ends that need to be connected to a constant temperature water circulation system. To reduce the number of joints, preferably, please refer to... Figure 6 , 7 8.

[0055] Two clamps 45 respectively cover the through holes 44 at both ends of the profile 43, and a sealing ring 49 is provided between the clamps 45 and the profile 43;

[0056] One of the clamps 45 is provided with an inlet 46 and an outlet 47 that are respectively connected to two through holes 44, and the other clamp 45 is provided with a water channel 48 that is respectively connected to two through holes 44. The sealing ring 49 is used to seal the gaps between the through holes 44 and the inlet 46, the through holes 44 and the outlet 47, and the through holes 44 and the water channel 48.

[0057] In this embodiment, one clamp 45 is provided with one inlet 46, one outlet 47 and one water channel 48, and another clamp 45 is provided with two parallel water channels 48, so that the four through holes 44 of the aluminum alloy profile are connected in series through three water channels 48, and the constant temperature water circulation system only needs to circulate the constant temperature liquid between the inlet 46 and the outlet 47.

[0058] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered as falling within the scope of protection of the embodiments of the present invention.
