Description

Technical Field

[0001] This invention relates to the field of gypsum board production technology, and more specifically to a gypsum board continuous alternating paper feeding device. Background Technology

[0002] In the existing gypsum board production process, edge sealing with edge-sealing paper is an operation in the preparation of finished gypsum board products. Since one roll of edge-sealing paper can seal a sufficiently long side of gypsum board, the current gypsum board production process usually uses a single roll of edge-sealing paper for each edge sealing operation. After the single roll is used up, it is manually changed. Compared to the overall gypsum board production process, manual roll changing may not have a significant impact on the production efficiency, but it still requires manual operation and machine downtime. Therefore, in practical applications, it is possible to replenish the edge-sealing paper rolls by continuously supplying multiple rolls to improve the continuity of gypsum board production and reduce manual labor and production line downtime. Thus, the continuous supply of edge-sealing paper rolls has become the main problem that needs to be solved.

[0003] The main problem is that the edge banding paper rolls usually need to be transported to a designated workstation first, and then spliced ​​mechanically. There is an interval in the travel of the two processes, and the gypsum board is always in a conveying state, which makes it difficult to splice the edge banding paper rolls to be used and those on the conveying path. Summary of the Invention

[0004] The purpose of this invention is to provide a gypsum board continuous alternating paper splicing supply device to solve the technical problem of poor connection between the supply and splicing of edge sealing paper rolls due to the lack of existing paper splicing structures or mechanical paper splicing.

[0005] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0006] A gypsum board continuous alternating paper feeding device includes:

[0007] The workstation platform has at least two mounting components for installing edge-sealing paper rolls arranged symmetrically at the center, and the edge-sealing paper rolls are able to rotate relative to the mounting components.

[0008] A drive component is disposed at the bottom of the workstation platform. The drive component is used to drive the workstation platform to rotate around the symmetry center of at least two mounting parts for a set period, so that the mounting parts on the workstation platform are replaced sequentially at a set workstation.

[0009] Specifically, the station platform rotates at a set cycle before the edge-sealing paper roll on the mounting component at the workstation is used up.

[0010] As a preferred embodiment of the present invention, a guide roller group is provided on one side of the workstation platform, and a traction roller group is provided on the sealing paper between the guide roller group and the workstation.

[0011] Before the drive assembly drives the workstation platform to rotate, the traction roller group is used to pull the sealing paper between the guide roller group and the workstation along a set path.

[0012] After the drive assembly drives the workstation platform to rotate once, the traction roller group returns to its initial position by rotating clockwise.

[0013] In a preferred embodiment of the present invention, when the drive assembly drives the workstation platform to perform one cycle rotation, the sealing paper between the traction roller group and the guide roller group is circumferentially tangent to the sealing paper roll that has rotated to an unused mounting piece on the workstation.

[0014] In a preferred embodiment of the present invention, the number of traction roller sets is one:

[0015] The traction roller assembly returns to its initial position by rotating clockwise around the workstation platform.

[0016] Or the number of the traction roller sets is two:

[0017] The two traction roller sets are arranged symmetrically about the center of the workstation platform, and the two traction roller sets rotate synchronously.

[0018] As a preferred embodiment of the present invention, the traction roller group includes a rotating arm rotatably mounted on the output shaft of the drive assembly and a servo motor for driving the rotating arm to rotate. A rotating roller is provided at the end of the rotating arm away from the servo motor. The rotating roller is mounted on the rotating arm via a rotating shaft and is perpendicular to the rotating arm.

[0019] The length of the rotating arm is greater than the radius of the workstation platform.

[0020] As a preferred embodiment of the present invention, the mounting component includes a shaft, which is mounted on the workstation platform via a linear bearing seat. A linear drive assembly is provided at the end of the shaft extending through the linear bearing seat to the lower part of the workstation platform. A plurality of one-way bearing seats are provided at equal intervals on the shaft, and the rotatable direction of the one-way bearing seats is opposite to the rotational direction of the drive assembly driving the workstation platform.

[0021] The linear drive assembly is used to drive the shaft to move in the vertical direction.

[0022] As a preferred embodiment of the present invention, the one-way bearing housing includes a one-way bearing body fixedly mounted on the shaft and a frustum seat mounted on the outer ring of the one-way bearing body, wherein the inner ring of the frustum seat and the outer ring of the one-way bearing body are keyed together.

[0023] As a preferred embodiment of the present invention, the edge sealing paper roll disposed on the mounting component protrudes from the circumferential edge of the workstation platform.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] This invention provides continuous paper supply for gypsum board edge sealing paper rolls by alternating between two edge sealing paper rolls at the workstation. Simultaneously, the movement of the two edge sealing paper rolls during the alternation process seamlessly connects the paper head of the edge sealing paper roll with the edge sealing paper roll in the conveying process, thereby making the continuous supply and paper receiving of gypsum board edge sealing paper rolls more natural and smooth.

[0036] 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.

[0037] like Figure 1 and Figure 2 As shown, the present invention provides a gypsum board continuous alternating paper feeding device, comprising:

[0038] The workstation platform 1 has at least two mounting components 2 for installing edge sealing paper rolls, which are centrally symmetrically arranged on the workstation platform 1 and can rotate relative to the mounting components 2.

[0039] The drive component 3 is located at the bottom of the workstation platform 1. The drive component 3 is used to drive the workstation platform 1 to rotate around the symmetrical center of at least two mounting parts 2 at a set period, so that the mounting parts on the workstation platform 1 are replaced sequentially at the set workstation.

[0040] The installation unit 2 at the workstation rotates the workstation platform 1 at a set cycle before the edge sealing paper roll is used up.

[0041] First, the technical solution provided by the present invention ensures that the paper receiving head 7 of the sealing paper roll on the mounting component 2 is always in a fixed position. The tangential angle between the paper receiving head 7 and the sealing paper roll can be designed according to actual needs, that is, it will not be affected by the rotation of the workstation platform 1 or the rotation of other sealing paper rolls on the mounting component 2 (it is at an ideal angle).

[0042] like Figure 1 As shown, in practical work, to more clearly explain the process of alternating supply of edge sealing paper rolls on the two mounting components 2, it is set as one mounting component ( Figure 1 (left side of the workstation platform) and two installation components ( Figure 1(Right side of the workstation platform), and assume that the edge sealing paper roll on one mounting component is currently in use (the edge sealing paper roll on one mounting component is set to be at the workstation), and the edge sealing paper roll on the second mounting component is waiting to receive paper.

[0043] (Without considering the traction roller group 5 below) When the sealing paper roll on the first mounting component is about to be completely used up, the drive assembly 3 drives the station platform 1 to rotate, and the linear speed of the sealing paper roll on the first mounting component increases (superimposed with the relative speed of the rotation of the station platform 1). At this time, the conveying path of the sealing paper on the conveying path is lengthened. Then, as the station platform 1 continues to rotate, the paper receiving head 7 of the sealing paper roll on the second mounting component will contact the surface of the sealing paper on the first mounting component that is on the conveying path (since the first and second mounting components are at the same height, the contact position between the paper receiving head 7 and the sealing paper is also at the same height). Then, the paper receiving head 7 of the sealing paper roll on the second mounting component and the sealing paper on the first mounting component that is on the conveying path stick together (that is, the paper receiving head 7 can be double-sided tape). After that, the second mounting component is in the station, and the sealing paper roll on the second mounting component begins to be conveyed. The remaining unused sealing paper roll on the first mounting component can be cut off and replaced in time.

[0044] Specifically, when the sealing paper roll 11 to be received moves to the position under the rotation of the workstation platform 1, as shown in the figure... Figure 2 The positions shown are where the positions of the edge sealing paper roll 11 to be received and the edge sealing paper roll 10 to be used up are interchanged. At this time, the edge sealing paper 9 being conveyed will come into contact with the edge sealing paper roll 11 to be received. At this time, the conveying direction of the edge sealing paper 9 and the rotation direction of the workstation platform 1 are as follows. Figure 2 As indicated by the arrow, the workstation platform 1 continues to rotate, causing the paper-connecting head 12 of the sealing paper roll 11 to contact and adhere to the sealing paper 9, completing the roll change operation. During this process, when the sealing paper roll 11 contacts the conveying sealing paper 9, a force is applied to the sealing paper roll 11. Friction causes the sealing paper roll to rotate, but the continued rotation of the workstation platform 1 ensures that the sealing paper roll 11 resists this frictional force, guaranteeing the stability and accuracy of the paper-connecting head adhesion process.

[0045] Of course, in order to consider the waste paper rate and minimize the paper splice segment, it is necessary to monitor the size of the edge sealing paper roll 10 that is about to be used up, and to cut the edge sealing paper roll 10 that is about to be used up.

[0046] In the above process, the rotation of the workstation platform 1 and the setting of the two mounting parts 2 are coupled to make the paper changing and paper receiving actions smoother.

[0047] However, there are certain problems with this approach, mainly in the following aspects:

[0048] The edge banding paper in use on the mounting component has surface tension during the conveying process. Since the rotation direction of the workstation platform 1 is opposite to the conveying direction, it will inevitably cause the tension of the edge banding paper 9 in the conveying process to change (the mounting component 2 itself does not provide tension control for the edge banding paper roll, that is, its conveying state depends on the edge banding structure of the gypsum board). In the actual process, it is easy to cause the edge banding paper roll to be overstretched and deformed, or cause the tension of the edge banding paper roll to suddenly change, affecting the paper splicing effect.

[0049] Therefore, such as Figure 3 and Figure 4 In this invention, a guide roller group 4 is provided on one side of the workstation platform 1 (the position of the guide roller group 4 is always fixed, that is, the edge sealing paper roll passing through the guide roller group 4 is transported to the side of the gypsum board for edge sealing operation), and a traction roller group 5 is provided on the edge sealing paper between the guide roller group 4 and the workstation.

[0050] Before the drive assembly 3 drives the station platform 1 to rotate, the traction roller group 5 is used to pull the sealing paper, which is located between the guide roller group 4 and the station, along a set path (the position after pulling is as follows). Figure 2 (As shown).

[0051] After the drive assembly 3 drives the station platform 1 for one cycle of rotation, the traction roller group 5 returns to the set initial position by rotating clockwise (the initial position is as follows). Figure 1 (as shown in the image).

[0052] In other words, before the paper receiving action is performed on the workstation platform 1, the edge sealing paper 9 in the conveying process is first pulled by the traction roller group 5. The surface tension of the edge sealing paper 9 in the conveying process before the paper is to be received is interfered by the traction roller group 5, so that the edge sealing paper in the conveying process between the traction roller group 5 and the guide roller group 4 is in a stable tension state (that is, if the workstation platform 1 is directly rotated, the tension of the edge sealing paper in the conveying process between the first mounting part and the guide roller group 4 will change). Then, the edge sealing paper roll on the second mounting part is connected to the edge sealing paper in the stable conveying process.

[0053] Furthermore, the key to achieving an ideal coupling state between the roll changing and paper splicing actions lies in the perfect coordination between the splicing point and the sealing paper conveying. Therefore, when the drive assembly 3 drives the station platform 1 to rotate once per cycle, the sealing paper between the traction roller group 5 and the guide roller group 4 is circumferentially tangent to the sealing paper roll on the unused mounting piece 2 rotated to the station. During the roll changing and paper splicing actions on the station platform 1, the traction roller group 5 first rotates with the station platform 1 to establish a stable sealing paper conveying and splicing state. The purpose of making the sealing paper roll 9 on one mounting piece tangent to the sealing paper roll on the second mounting piece that has been replaced at the station is to establish the connection point between the two. This allows the sealing paper in the conveying stage to adhere to the circumferential surface of the new sealing paper roll replaced at the station while simultaneously applying radial splicing pressure.

[0054] That is, the point of tangency between the sealing paper between the traction roller group 5 and the guide roller group 4 and the sealing paper roll on the unused mounting part 2 rotated to the station coincides with the position of the paper receiving end 7 of the sealing paper roll on the second mounting part that has been replaced to the station (ideally), or the position of the point of tangency is slightly larger than the position of the paper receiving end 7 in the counterclockwise direction of the sealing paper roll (considering that the two can be tightly pressed together to ensure complete adhesion).

[0055] At the same time, since the sealing paper roll on the second mounting component has completed the paper splicing, the sealing paper roll on the first mounting component has not yet completely detached from the traction roller group. That is to say, the sealing paper 9 on the first mounting component, which is being conveyed, still maintains a certain tension on the paper surface until the paper splicing is completed, and then the sealing paper 9 on the first mounting component, which is being conveyed, detaches from the traction roller group 5. This ensures that the sealing paper roll on the second mounting component can stably transfer and transition the surface tension after the paper splicing.

[0056] In the above, Figure 2 After completing the paper receiving action, the middle traction roller group 5 continues to rotate clockwise around the workstation platform, returning to its original position. Figure 1 At the initial position, it awaits the next paper change and paper splicing action. Specifically, there is one traction roller group 5:

[0057] The traction roller group 5 returns to its initial position by rotating clockwise around the workstation platform 1.

[0058] To minimize the rotation angle of the traction roller group 5 during a single roll changing and paper splicing cycle, the present invention can be configured to have two traction roller groups 5:

[0059] Two traction roller sets 5 are symmetrically arranged around the center of the workstation platform 1, and the two traction roller sets 5 rotate synchronously. That is, the first traction roller set 5 arrives at... Figure 2 When the second traction roller group is in the middle position, it is just in the middle position. Figure 1The set position in the middle.

[0060] To further illustrate the working principle described above, the present invention provides a specific embodiment of the traction roller group 5, which includes a rotating arm 51 rotatably mounted on the output shaft of the drive assembly 3 and a servo motor 52 that drives the rotating arm 51 to rotate. A rotating roller 53 is provided at the end of the rotating arm 51 away from the servo motor 52. The rotating roller 53 is mounted on the rotating arm 51 through a rotating shaft 54 ​​and is perpendicular to the rotating arm 51.

[0061] The length of the rotating arm 51 is greater than the radius of the workstation platform 1.

[0062] Of course, the traction roller group 5 in this invention can be set up independently of the workstation platform 1. Therefore, more freedom is needed in resetting the initial position of the rotating roller 53, and it must avoid the sealing paper being transported.

[0063] Furthermore, such as Figure 4 and Figure 5 As shown, in order to reduce the replacement cycle of the sealing paper roll on the mounting component 2, this invention provides a specific implementation method for the mounting component 2. The mounting component 2 includes a shaft 21, which is mounted on the workstation platform 1 via a linear bearing seat 22. A linear drive assembly 3 is provided at the end of the shaft 21 extending through the linear bearing seat 22 to the lower part of the workstation platform 1. Multiple one-way bearing seats 23 are evenly spaced on the shaft 21, and the rotatable direction of the one-way bearing seats 23 is opposite to the rotational direction of the workstation platform 1 driven by the drive assembly 3. The linear drive assembly 3 is used to drive the shaft 21 to move vertically.

[0064] Multiple one-way bearing seats 23 are used to mount the edge sealing paper roll 8 and provide one-way rotation of the edge sealing paper roll 8. Of course, the purpose of setting the one-way bearing seats 23 is to prevent the edge sealing paper roll 8 from easily rotating relative to the shaft 21 due to the existence of rotational inertia during the rotation of the workstation platform 1, thereby further ensuring the fixed position of the paper receiving head 7 and improving the accuracy of the paper receiving action.

[0065] Specifically, the one-way bearing housing 23 includes a one-way bearing body 24 fixedly mounted on the shaft 21 and a frustum 25 mounted on the outer ring of the one-way bearing body 24. The inner ring of the frustum 25 and the outer ring of the one-way bearing body 24 are keyed together, which facilitates the installation and removal of the sealing paper roll 8.

[0066] Furthermore, in practical applications, this invention requires the dimensions of the sealing paper roll and the station platform 1 to be compatible. During the paper changing process, the sealing paper pulled by the traction roller group 5 and on the transmission path can be tangent to the new sealing paper roll on the station, so that the paper head 7 and the sealing paper make tangential contact and connection. Considering the overall size and structure, the radius of the sealing paper roll is less than or equal to the radius of the station platform 1, so that the sealing paper roll set on the mounting part 2 protrudes from the circumferential edge of the station platform 1.

[0067] To further explain, in order to maintain the rotational stability of the workstation platform 1, a support ring frame 6 is provided at the bottom of the workstation platform 1. The top of the support ring frame 6 is rotatably connected to the bottom outer ring of the workstation platform 1, that is, the workstation platform 1 and the support ring frame 6 can rotate relative to each other.

[0068] Due to structural limitations and considering the ease of replacing the sealing paper roll on mounting component 1, the servo motor of the traction roller group 5 is placed at the bottom. In this way, the support ring frame 6 can also rotate synchronously while the rotating arm 51 is driven to rotate by the servo motor 52.

[0069] As further explained, the linear drive assembly 3 (specifically, the pneumatic cylinder, hydraulic cylinder, or lead screw-nut pair transmission assembly) in this invention is powered by an electric slip ring mounted on the drive assembly 3.
