Description

Technical Field

[0001] The utility model relates to the technical field of paper material pressing, in particular to a pressing device for paper material processing with good tensile force. Background Art

[0002] The tensile strength of paper refers to the tensile strength of paper when stretched, which can also be understood as the ability of paper to resist tearing under force. This property is usually used to measure the strength and durability of paper. When increasing the tensile strength of paper, it is usually laminated using a laminating device.

[0003] A Chinese patent with authorization announcement number CN211868784U discloses a laminating device for paper product processing. When a laminating part is used, the setting of a buffer part and a clamping seat can reduce the vibration generated during the laminating process, ensure the normal use of the device, ensure the laminating effect of the paper, better laminarize the paper, facilitate the subsequent use of the paper, and to a certain extent improve the service life of the device.

[0004] However, the pressing device mentioned above uses a hydraulic cylinder to press it during the pressing process. Once the hydraulic cylinder loses control and presses down during the loading and unloading process, it is easy to cause a certain impact force on the hands of the staff, posing corresponding safety hazards.

[0030] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0031] Embodiment 1

[0032] like Figure 1-Figure 4 As shown, the utility model proposes a laminating device for paper processing with good tensile force, comprising a laminating table 1, a reciprocating assembly and an intermittent driving mechanism. A frame 2 is arranged at the bottom of the laminating table 1, a rectangular groove is opened in the middle, a limiting member is arranged in the rectangular groove, and a placing table 3 is connected to the placing table 3 through the limiting member. A bottom mold 4 is placed on the placing table 3, and a laminating assembly is arranged above the bottom mold 4. The reciprocating assembly and the intermittent driving mechanism are both arranged on the inner side of the frame 2, and the reciprocating assembly and the intermittent driving mechanism cooperate to drive the placing table 3 to move intermittently back and forth, thereby switching the position of the bottom mold 4 when loading and unloading.

[0033] like Figure 2 As shown, the limiting member includes a limiting column 5 and a limiting sleeve 6 . The limiting column 5 is provided in two groups. The limiting sleeve 6 is slidably provided on both groups of limiting columns 5 . The placing table 3 is installed on the two groups of limiting sleeves 6 .

[0034] Wherein, through the cooperation between the limiting column 5 and the limiting sleeve 6, the placing platform 3 can move horizontally along the limiting column 5 under the action of external force.

[0035] like Figure 1As shown, the pressing assembly includes a hydraulic cylinder 7 and a pressing plate 8. An L-shaped frame 21 is provided on the pressing table 1, and the hydraulic cylinder 7 is installed on the L-shaped frame 21. The output end of the hydraulic cylinder 7 is connected to the pressing plate 8. The bottom mold 4 has a material changing position and a pressing position. When the bottom mold 4 is at the material changing position, it is in a horizontally misaligned state with the pressing plate 8. When the bottom mold 4 is at the pressing position, it is in an aligned state with the pressing plate 8.

[0036] Embodiment 2

[0037] like Figure 1-Figure 4 As shown, the utility model proposes a laminating device for paper processing with good tensile force. On the basis of the above embodiments, this embodiment also records in detail the specific structure of the reciprocating component and the intermittent driving mechanism, as well as the connection method between the two.

[0038] like Figure 2 and Figure 3 As shown, the reciprocating assembly includes a U-shaped frame 9, a connecting plate 11 and a fixed frame 13. The U-shaped frame 9 is installed at the bottom of the pressing table 1. The U-shaped frame 9 rotates and passes through a connecting shaft 10. A connecting plate 11 is arranged at the top of the connecting shaft 10. A guide shaft 12 is arranged at the eccentric position of the upper end surface of the connecting plate 11. A fixed frame 13 is also arranged at the bottom of the placement table 3. The fixed frame 13 is provided with a strip groove 14 for the guide shaft 12 to pass through.

[0039] Among them, the intermittent driving mechanism intermittently drives the connecting shaft 10 to rotate 180 degrees, and then drives the connecting disk 11 to rotate synchronously. During the rotation of the connecting disk 11, the guide shaft 12 thereon pushes the groove wall of the strip groove 14, and then drives the placement table 3 to move outward to the unloading position under the guidance of the limiter. After moving to the unloading position, it is in the intermittent time period of the intermittent movement process, and the staff will change the material. After the material change is completed, the intermittent time period ends, and the connecting shaft 10 rotates 180 degrees again, and at this time, the placement table 3 is driven to return to the pressing position.

[0040] like Figure 2 and Figure 4 As shown, the intermittent drive mechanism includes a vertical plate 15, a turntable 16, a special-shaped gear 18 and a push plate 20. The vertical plate 15 is vertically arranged in the frame 2, and a motor 17 is installed on the side of the vertical plate 15. The output end of the motor 17 is connected to the turntable 16. A plurality of groups of tooth grooves are opened on the outer periphery of the turntable 16. A push plate 20 is arranged at the eccentric position of the side end surface of the turntable 16. The bottom end of the connecting shaft 10 is connected to the special-shaped gear 18. A plurality of groups of tooth blocks matching the tooth grooves are arranged on both sides of the special-shaped gear 18. A fixing column 19 is also symmetrically arranged at the eccentric position of the lower end surface of the special-shaped gear 18.

[0041] The motor 17 drives the turntable 16 to rotate. During the rotation, the push plate 20 pushes the fixed shaft to drive the gear to rotate. When the gear rotates, the tooth block extends into the tooth groove as the turntable 16 rotates. That is, one rotation of the turntable 16 will drive the gear to rotate half a circle, and the gear will then drive the connecting shaft 10 to rotate half a circle.

[0042] In summary, when the utility model is used, the paper material to be pressed is placed on the bottom mold 4 in advance, the bottom mold 4 is placed on the placement table 3, the intermittent drive mechanism is started, the motor 17 drives the turntable 16 to rotate one circle, and the connecting shaft 10 drives the turntable 16 to rotate half a circle. At this time, the connecting disk 11 rotates synchronously. During the rotation of the connecting disk 11, the guide shaft 12 thereon pushes the groove wall of the strip groove 14, thereby driving the placement table 3 to move outward to the pressing position under the guidance of the limiter. At this time, the intermittent motion mechanism is still running, and the connecting shaft 10 is in the intermittent section of its operation. During the intermittent section, the hydraulic cylinder 7 The pressing plate is driven to move downward to press the paper. After the pressing is completed, the intermittent section stops, and the connecting shaft 10 rotates half a circle again. The placement table 3 is reset to drive the pressed paper back to the outside material changing position. The staff removes the bottom mold 4 and puts the new bottom mold 4 on the placement table 3. During the material changing process, the connecting shaft 10 is in the intermittent stage again. After the material changing is completed, the connecting shaft 10 rotates again, that is, a series of processes of loading, moving, pressing, returning and changing materials are realized as a whole. There is no need to load and unload materials under the pressing assembly, which effectively avoids the safety hazards caused by equipment out of control to the staff.

[0043] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
