[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A pressing structure for producing sound insulation sheets, comprising a workbench, a limit bolt, and two fixing seats arranged on the workbench, and further comprising:

[0007] Transmission mechanism: The transmission mechanism is arranged on the two fixed seats;

[0009] In this solution, the rotating rod and the rotating shaft can be connected into a whole. By limiting the limit block on one side of the rotating shaft in the limit groove of the rotating rod, clamping the connecting hole and the fixing hole through the limit bolt, and limiting the position using the limit ring, the pressure roller can be stably installed on the circumferential outer wall of the rotating shaft. When the pressure roller needs to be replaced, the limit bolt is released. Since one side of the rotating shaft is connected by a cross coupling, the rotating shaft on one side of the limit block can be lifted and moved, and then the pressure roller is removed and replaced with a new pressure roller, and then limited again. The replacement is simple, which can meet the needs of different manufacturers for pressing sound insulation sheets. The operation is convenient and fast, and the pressing efficiency is higher.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0021] The utility model discloses a pressing structure for producing sound insulation sheets, which is mainly used in scenarios where traditional pressing structures for producing sound insulation sheets are used. Different manufacturers require different sound insulation sheets and require different pressing rollers for pressing. It is inconvenient to completely dismantle the pressing rollers, which is time-consuming and labor-intensive, and the pressing efficiency is low.

[0022] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A pressing structure for producing a sound insulation sheet includes a workbench 1, a limit bolt 12, and two fixing seats 4 provided on the workbench 1, and further includes:

[0023] Transmission mechanism: The transmission mechanism is arranged on two fixed seats 4;

[0024] A first connecting block 8 and a second connecting block 9 are respectively provided on the inner walls of the fixed seat 4, a rotating rod 11 is provided on the inner wall of a second connecting block 9, a limiting groove 13 is opened on the circumferential outer wall of the rotating rod 11 near the top, and a connecting hole is opened on the inner wall of the limiting groove 13, a rotating shaft 18 is connected to the outer wall of one side of the second connecting block 9 through a cross coupling, a pressure roller 7 is provided on the circumferential outer wall of the rotating shaft 18, a limiting block 14 is fixedly connected to the outer wall of one side of the rotating shaft 18, a fixing hole is opened on the outer wall of one side of the limiting block 14, a limiting bolt 12 is used in conjunction with the connecting hole and the fixing hole respectively, and a limiting ring 19 is provided at one end of the limiting bolt 12.

[0025] During operation, the pressure roller 7 is movably mounted on the outer circumferential wall of the rotating shaft 18. The pressure roller 7 can be stably mounted by securing the rotating shaft 18 between the rotating rod 11 and the rotating shaft 18. The pressure roller 7 is stably mounted by positioning the stop block 14 on one side of the rotating shaft 18 within the stop groove 13 of the rotating rod 11, clamping the stop bolt 12 between the connecting hole and the fixing hole, and limiting the position using the stop ring 19. When the pressure roller 7 needs to be replaced, the stop bolt 12 is released. Since the rotating shaft 18 on one side is connected via a cross coupling, the position of the rotating shaft 18 can be moved. The rotating shaft 18 on the side of the stop block 14 is then lifted and moved. The pressure roller 7 is then removed and replaced with a new one, which is then secured again.

[0026] Among them, the limit block 14 is adapted to the limit groove 13, the positions of the connecting hole and the fixing hole correspond to each other, and the limit bolt 12 is adapted to the connecting hole and the fixing hole respectively. In this way, the limit block 14 is better limited in the limit groove 13, so that the rotating shaft 18 and the rotating rod 11 are connected into a whole. At this time, the positions of the connecting hole and the fixing hole correspond to each other, and the limit bolt 12 is used to limit between the fixing hole and the connecting hole to fix the rotating shaft 18 and the rotating rod 11, thereby fixing and stabilizing the pressure roller 7.

[0027] Among them, the outer walls around the limit block 14 are all set to a rounded structure, and the size of the rotating shaft 18 is slightly larger than the size of the limit block 14. In this way, the rounded structure of the limit block 14 makes the limit block 14 more smoothly limited in the limit groove 13. The different sizes make the pressure roller 7 on the rotating shaft 18 not hindered by the limit block 14 during installation, making installation and disassembly convenient, and better clamping and removal.

[0028] Reference Figure 1 、 Figure 2 and Figure 3In a preferred embodiment, the transmission mechanism includes a common connecting shaft 15 provided on the outer walls of the two opposite sides of the first connecting blocks 8, a support roller 6 is provided on the circumferential outer wall of the connecting shaft 15, a motor 10 is provided on the outer wall of one side of the first connecting block 8, one end of the output shaft of the motor 10 is connected to the connecting shaft 15, the connecting shaft 15 passes through the end of the first connecting block 8 away from the motor 10 and is provided with a driving gear 16, and one end of the rotating rod 11 is provided with a driven gear 17, and the driving gear 16 is meshed with the driven gear 17.

[0029] Specifically, when the sound insulation sheet is pressed, the motor 10 is started, and the motor 10 drives the connecting shaft 15 to rotate, so that the support roller 6 rotates, and the driving gear 16 connected to the connecting shaft 15 also rotates synchronously. Under the meshing action of the driving gear 16 and the driven gear 17, the driven gear 17 rotates synchronously, so that the pressure roller 7 and the support roller 6 rotate synchronously, and then the transmitted sound insulation sheet is pressed. The support roller 6 supports and links the pressure roller 7 to press at the same time, and cooperates with each other to press the sound insulation sheet into the required state.

[0030] Reference Figure 2 and Figure 3 In a preferred embodiment, a cylinder 5 is provided on the top outer wall of the two fixed seats 4, one end of the telescopic rod of the cylinder 5 passes through the fixed seat 4 and is connected to the second connecting block 9, and the pressure roller 7 is used in conjunction with the support roller 6.

[0031] Specifically, the operation of the cylinder 5 can drive the second connecting block 9 to move, thereby changing the position of the pressure roller 7, so that the pressure roller 7 moves to a position close to the support roller 6. The proximity between the two can make the pressing effect of the sound insulation plate better under the transmission action.

[0032] It should be noted that the first connecting block 8 is fixedly connected to the inner wall of the fixing seat 4 , and the second connecting block 9 is slidably connected, and the position of the second connecting block 9 is moved by the cylinder 5 to adjust the position of the pressure roller 7 .

[0033] Reference Figure 1 In a preferred embodiment, mounting seats 2 are fixedly connected to both sides of the top outer wall of the workbench 1, three support columns are provided on the outer walls on the opposite sides of the two mounting seats 2, and the same transition platform 3 is fixedly connected to the circumferential outer walls of the three support columns.

[0034] Specifically, the pressed sound insulation sheets are transported and transferred through the transition platform 3. The transition platform 3 can be used to place the sound insulation sheets, and a certain collection time is reserved for better transfer and classification of the sound insulation sheets.

[0035] Working principle: During use, when the pressure roller 7 needs to be replaced, the rotation shaft 18 on one side of the limit block 14 can be lifted and moved because one side of the rotating shaft 18 is connected by a cross coupling, and then the pressure roller 7 is removed and replaced with a new pressure roller 7. After the new pressure roller 7 is replaced, the limit block 14 is limited in the limit groove 13 of the rotating rod 11, and the limit bolt 12 is clamped between the connecting hole and the fixing hole, and the limit ring 19 is used to limit the rotating rod 11 and the rotating shaft 18 is fixed and stabilized, thereby fixing the pressure roller 7. Then, according to the position of the support roller 6, the cylinder 5 works to drive the second connecting block 9 to move, so that the pressure roller 7 moves to a position close to the support roller 6, and then the motor 10 is started. Because the driving gear 16 is meshed with the driven gear 17, the pressure roller 7 and the support roller 6 rotate synchronously, thereby pressing the transmitted sound insulation sheet. The pressed sound insulation sheet is transported and transferred through the transition platform 3.

[0036] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The replacements described may be partial structures, devices, or method steps, or they may be complete technical solutions. Any equivalent replacements or modifications based on the technical solution and the concept of the present invention shall be covered by the scope of protection of the present invention.
