Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plastic forming of treatment tower, and particularly relates to a demolding device based on glass steel treatment tower production. BACKGROUND

[0002] The glass steel treatment tower is a kind of purification equipment, and a cylindrical shell is usually produced by using a glass fiber extrusion winding process. The glass steel treatment tower can not only ensure consistency and quality stability of products, but also can design a tower body structure with high strength and high corrosion resistance by controlling winding angles and layers.

[0003] On the automatic production line, the proportion of resin and glass fiber is controlled to ensure uniform material distribution of each part, and then the winding cylinder is wound while the adhesive is applied, so that the fiber is solidified in a column shape on the winding cylinder to form a shell with a required thickness. Then, the moving lifting support equipment is used to support the winding cylinder and the shell, the clamping equipment is used to clamp the shell, and finally the winding cylinder is pulled out of the shell to complete demolding.

[0004] Since the outer circumferential surface of the winding cylinder and the inner circumferential surface of the shell are in surface contact, the friction between them is large. In addition, the fiber needs to be tightly wound on the winding cylinder, so that a pre-tightening force is applied to the winding cylinder, which increases the friction between the shell and the winding cylinder. Moreover, since there is no gap between the shell and the winding cylinder, the clamping equipment can only apply a clamping force to the shell towards the winding cylinder to clamp the shell. This clamping force further increases the friction between the shell and the winding cylinder. Only when the friction between the clamping equipment and the shell is greater than the friction between the shell and the winding cylinder, the winding cylinder can be pulled out of the shell. This requires a large clamping force, which is easy to damage the surface of the shell. In addition, it is not suitable for shells with small thickness, otherwise it will cause deformation.

[0005] The above information disclosed in the background section is only used to strengthen the understanding of the background of the present disclosure, and therefore it can include information that does not constitute prior art known to those of ordinary skill in the art. SUMMARY

[0006] The purpose of the present application is to reduce the surface contact between the shell and the winding cylinder, and to eliminate the pre-stress of the fiber wound on the winding cylinder, thereby reducing the friction between the winding cylinder and the shell and the required clamping force, so as to be suitable for exhaust treatment tower shells with small thickness, and to solve the above problems in the art.

[0007] In order to achieve the above object, the present application provides the following technical scheme: A demolding device based on a glass steel treatment tower production, used for demolding after a fiber is wound out of a long columnar waste gas treatment tower shell, comprising a winding drum, a plurality of mobile lifting support devices for supporting the winding drum and the shell, and a clamping device for clamping the shell, the winding drum comprises a roller shaft, a first arc plate and a second arc plate arranged in an array on the outer circumference of the roller shaft, and a transmission assembly for driving the first arc plate and the second arc plate to gather towards the central axis of the roller shaft in sequence, there is a cavity between the first arc plate and the second arc plate and the shell after the first arc plate and the second arc plate gather towards the central axis of the roller shaft, the two side surfaces of the first arc plate are parallel, and the two side surfaces of the first arc plate are mirror image arranged with respect to the plane in which the central axis of the roller shaft is located, the second arc plate has an acute angle between the two side surfaces, and the second arc plate and the side surface of the first arc plate form a hollow column when they are fitted, and the outer circumferential surface of the hollow column is fitted with the inner circumferential surface of the shell.

[0008] The transmission assembly drives the first arc plate and the second arc plate to gather in sequence, so that the outer circumferential surface of the hollow column formed by the first arc plate and the second arc plate is separated from the inner circumferential surface of the shell, the pre-tightening force applied by the fiber wound on the hollow column to the central axis of the roller shaft is eliminated, and the contact area between the winding drum and the inner circumferential surface of the shell is reduced.

[0009] Preferably, the transmission assembly comprises a first swing lever and a second swing lever rotatably connected with the inner circumferential surfaces of the first arc plate and the second arc plate, a first connecting rod and a second connecting rod rotatably connected with the first swing lever and the second swing lever, a first circular ring and a second circular ring rotatably connected with the ends of the first connecting rod and the second connecting rod, and a first driving member and a second driving member threadedly connected with the outer circumferential surfaces of the first circular ring and the second circular ring, the ends of the first swing lever and the second swing lever are rotatably connected with the outer circumferential surface of the roller shaft, the first circular ring and the second circular ring are axially slidably connected with the outer circumferential surface of the roller shaft, and the first driving member and the second driving member are rotatably connected with the roller shaft.

[0010] Preferably, the first swing lever on the first arc plate has a plurality of linear array arrangements, and a first transmission rod is rotatably installed on the plurality of first swing levers.

[0011] Preferably, the second swing lever on the second arc plate has a plurality of linear array arrangements, and a second transmission rod is rotatably installed on the plurality of second swing levers.

[0012] Preferably, the length of the first swing lever is the same as the length of the second swing lever.

[0013] Preferably, when the first swing lever and the second swing lever are perpendicular to the central axis of the roller shaft, the first arc plate and the second arc plate form the hollow column.

[0014] Preferably, the first driving member and the second driving member are respectively located at the two ends of the roller shaft, and the swing directions of the first swing lever and the second swing lever are opposite.

[0015] Preferably, the gap width between the plurality of first arc plates is greater than the thickness of the second swing lever and the second transmission rod when the first circular ring is unable to continue to move axially within the first driving member.

[0016] Preferably, the number of the moving lifting support devices is greater than or equal to 4, and at least two of the moving lifting support devices provide support for the shell.

[0017] Preferably, the clamping device comprises a mounting frame, four electric telescopic rods mounted diagonally on the mounting frame, and a clamp mounted on the electric telescopic rods, the clamp providing a clamping force in the opposite direction on the inner wall and the outer wall of the shell.

[0018] In the above technical solution, the present application provides technical effects and advantages:

[0019] 1. The present application improves the existing winding drum, so that the outer peripheral surface of the winding drum is composed of first arc plates and second arc plates. After the first arc plates and the second arc plates are sequentially gathered towards the roller shaft, the pre-tightening force exerted by the fiber wound on the winding drum on the central axis of the roller shaft is eliminated, and the problem of increased friction caused by the pre-tightening force and difficult demolding is eliminated.

[0020] 2. The first arc plates and the second arc plates are sequentially gathered towards the roller shaft, so that the surface contact between the original winding drum and the inner peripheral surface of the shell becomes contact between the individual second arc plates and the inner peripheral surface of the shell, the contact area is reduced, the friction is reduced, and the force required to extract the winding drum while keeping the shell stationary is reduced.

[0021] 3. Meanwhile, after the first arc plates and the second arc plates are gathered, a cavity will appear between the shell and the second arc plates, so that the clamping device can change the style of the clamp to change the clamping method. Instead of applying a force towards the central axis of the shell to the shell, a force is applied to the inner peripheral surface and the outer peripheral surface of the shell in opposite directions for clamping, so that deformation of the shell caused by clamping does not occur when the wall thickness of the shell is small.

[0022] 4. Compared with the existing technology, only a small improvement is made to the winding drum, and the entire production line is not significantly changed, so that the cost of upgrading and replacement is greatly reduced.

[0023] 5. When the first arc plates and the second arc plates in the present application are unfolded, the hollow cylindrical outer peripheral surface formed can still be circular, which not only allows the application of a release agent, but also ensures that the inner peripheral surface of the shell is circular, thereby retaining the required functions of the original winding drum.

DETAILED DESCRIPTION

[0036] In order for those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0037] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the drawings in the specification and specific embodiments.

[0038] The present application provides a demolding device based on a glass steel treatment tower production as shown in Figures 1-9 The present application provides a demolding device based on a glass steel treatment tower production as shown in Figure 8 and Figure 9As shown, we set the two side faces of the first arc plate 2b as parallel planes, and the two side faces of the first arc plate 2b are mirror images relative to the plane where the central axis of the roller shaft 2a is located, while the two side faces of the second arc plate 2c have an acute angle between them, so that we can first gather the first arc plate 2b towards the roller shaft 2a, and then gather the second arc plate 2c towards the roller shaft 2a, the movements of the two do not occur at the same time, and there is no interference, and when it is unfolded, it can form a hollow cylinder 2f with a smooth outer peripheral surface, and after gathering, the first arc plate 2b and the second arc plate 2c will be separated from the inner peripheral surface of the shell 1, at this time the pre-tightening force originally formed due to the winding of the fiber will not act on the winding drum 2 to increase the friction, and at the same time, the gathered winding drum 2 will not have a large surface contact with the inner peripheral surface of the shell 1, at most one or two second arc plates 2c have a small surface contact with the inner peripheral surface of the shell 1, further reducing the friction, and a cavity 2e is formed between the gathered winding drum 2 and the inner peripheral surface of the shell 1, at this time we can replace the clamp 4c on the clamping device 4, so that the clamp 4c does not exert a clamping force on the surface of the shell 1 towards the winding drum 2, but the side of the clamp 4c is inserted into the cavity 2e, and a clamping force is exerted on the inner and outer peripheral surfaces of the shell 1, that is, the side wall of the shell 1 is clamped, so that the shell 1 will not be thinned and deformed;

[0039] In order to ensure the transmission of the first arc plate 2b and the second arc plate 2c, we design a transmission assembly 2d on the roller shaft 2a, so that a plurality of arrayed first swing rods 2d1 and second swing rods 2d2 are rotatably installed on each first arc plate 2b and second arc plate 2c, the ends of the first swing rods 2d1 and the second swing rods 2d2 are rotatably connected with the roller shaft 2a, and a first transmission rod 2d9 and a second transmission rod 2d10 are rotatably installed on the first swing rods 2d1 and the second swing rods 2d2 in the same row, and a first driving member 2d7 and a second driving member 2d8 are rotatably installed at both ends of the roller shaft 2a, a first circular ring 2d5 and a second circular ring 2d6 are threadedly connected on the first driving member 2d7 and the second driving member 2d8, a first connecting rod 2d3 is rotatably installed between the first circular ring 2d5 and the first swing rod 2d1, and a second connecting rod 2d4 is rotatably installed between the second circular ring 2d6 and the second swing rod 2d2, and the first circular ring 2d5 and the second circular ring 2d6 are both axially slidably connected with the outer peripheral surface of the roller shaft 2a, so that by rotating the first driving member 2d7, the first driving member 2d7 will drive the first circular ring 2d5 to move axially on the roller shaft 2a, the first circular ring 2d5 will drive the first connecting rod 2d3 to move, and the first connecting rod 2d3 will drive the first swing rod 2d1 to swing, and similarly, driving the second driving member 2d8, the second swing rod 2d2 will swing;

[0040] At the same time, we set the first swing rod 2d1 and the second swing rod 2d2 to be perpendicular to the axis of the roller shaft 2a, and the first arc plate 2b and the second arc plate 2c form a hollow column 2f, so that the fiber wound on the hollow column 2f will transmit the force vertically to the roller shaft 2a instead of to the connecting rod. To this end, we design the first swing rod 2d1 and the second swing rod 2d2 to be the same length. In order to ensure that the first arc plate 2b does not affect the gathering of the second arc plate 2c after gathering, we make the first ring 2d5 located when the first driving member 2d7 cannot continue to move axially, so that the gap width between two adjacent first arc plates 2b is greater than the sum of the thickness of the second swing rod 2d2 and the second transmission rod 2d10. When the roller shaft 2a rotates, it will drive the first arc plate 2b and the second arc plate 2c to rotate through the first swing rod 2d1 and the second swing rod 2d2.

[0041] When the product is working, first, the first swing rod 2d1 and the second swing rod 2d2 are perpendicular to the axis of the roller shaft 2a. At this time, the side walls of the first arc plate 2b and the second arc plate 2c are in contact with each other to form a hollow column 2f. At this time, the outer surface of the hollow column 2f is sprayed with a release agent. Then, the fiber is wound on the outer surface of the hollow column 2f according to the production method in the prior art to form a predetermined length of the outer shell 1. After that, the winding drum 2 is moved above the moving lifting support device 3 and is lowered, so that at least two moving lifting support devices 3 support the outer shell 1. Then, the first driving member 2d7 is manually rotated to make the first arc plate 2b gather towards the roller shaft 2a. At this time, the first arc plate 2b is separated from the inner surface of the outer shell 1. Then, the second driving member 2d8 is rotated to make the second arc plate 2c gather towards the roller shaft 2a. During the gathering process of the second arc plate 2c, the horizontal height of the roller shaft 2a will gradually decrease, and the bottom of the circle formed by the second arc plate 2c will always be in contact with the bottom of the inner surface of the outer shell 1, so that the weight of the winding drum 2 is transmitted to the moving lifting support device 3 through the outer shell 1. When the cavity 2e appears, the moving lifting support device 3 pushes the outer shell 1 towards the clamping device 4, so that one end of the clamp 4c of the clamping device 4 is located in the cavity 2e and the other end is located outside the outer shell 1. Then, the clamp 4c is started to clamp the outer shell 1. After that, according to the same method in the prior art, the first driving member 2d7 is pulled away from the clamping device 4. The first driving member 2d7 pulls the roller shaft 2a, which pulls the first arc plate 2b and the second arc plate 2c out of one end of the outer shell 1 through the first swing rod 2d1 and the second swing rod 2d2. When one end of the second arc plate 2c extends out of the outer shell 1, a moving lifting support device 3 is started to support the second arc plate 2c and follow the movement of the second arc plate 2c as it is pulled out. Then, as the second arc plate 2c is pulled out, the moving lifting support device 3 supports the second arc plate 2c to avoid the situation that the second arc plate 2c and the roller shaft 2a are tilted due to the center of gravity. When the winding drum 2 is completely pulled out of the outer shell 1, the demolding of the outer shell 1 is completed.

[0042] It is important to note that the construction and arrangement of the application shown in the various exemplary embodiments is illustrative only. Although only a few embodiments have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter described in the application.
