Abstract
Description
Technical Field
[0001] The present application relates to the technical field of printing paper, and in particular to a printing paper embossing device. Background Art
[0002] Printing paper is a general term for papers used for various printed materials. For example: letterpress printing paper, offset printing paper, high-gloss cardboard, newsprint, writing paper, etc.
[0003] An embossing machine generally embosses paper through an embossing roller and a side pressure roller. However, both the embossing roller and the side pressure roller use roller bodies such as wool rollers and nylon rollers. Due to the material of the roller body, the strength is poor. Therefore, it is easy to deform after a long time of roller pressing treatment. Moreover, the above roller bodies are prone to heat generation during the roller pressing process, making the deformation of the roller body more serious, thereby reducing the embossing effect on the paper. Summary of the Invention
[0004] In order to reduce the risk of deformation of the roller body and improve the embossing effect on the paper, the present application provides a printing paper embossing device.
[0005] A printing paper embossing device provided by the present application adopts the following technical solutions: A printing paper embossing device includes a machine body, an embossing roller, a side pressure roller, a driving mechanism, a first roller body and a second roller body, and a cooling mechanism. The driving mechanism is used to drive the embossing roller and the side pressure roller to rotate synchronously and emboss the paper. The first roller body and the second roller body are rotatably installed on the machine body and are made of metal and respectively abut against the embossing roller and the side pressure roller for support and positioning. The cooling mechanism is arranged on the machine body and is used to cool down the first roller body and / or the second roller body.
[0006] By adopting the above technical solutions, the driving mechanism drives the embossing roller and the side pressure roller to rotate synchronously, so that the paper is embossed through the embossing roller and the side pressure roller. The first roller body and the second roller body abut against the embossing roller and the side pressure roller for support and positioning. The first roller body and the second roller body are made of metal, which can further improve the support effect on the embossing roller and the side pressure roller. At the same time, the cooling mechanism cools down the first roller body and / or the second roller body, so as to be able to cool down the embossing roller and / or the side pressure roller. Therefore, the risk of deformation of the embossing roller and the side pressure roller is greatly reduced. Coupled with the synchronous rotation of the embossing roller and the side pressure roller, the risk of heat generation due to friction between the embossing roller and the side pressure roller and the paper is greatly reduced, and the risk of deformation of the embossing roller and the side pressure roller is further reduced. Therefore, the embossing quality of the paper is improved.
[0007] Optionally, the first roller body, the embossing roller, the side pressure roller and the second roller body are vertically spaced from top to bottom. A cooling cavity is formed in the first roller body. The cooling mechanism includes: A cooling box, which is arranged on the machine body and filled with coolant; A pump body, which is arranged in the cooling box; An inlet pipe and an outlet pipe, which are respectively arranged on the pump body and the cooling box and are both communicated with the cooling cavity.
[0008] By adopting the above technical solution, when the pump body starts, the coolant in the cooling box is input into the cooling cavity through the inlet pipe, and then the coolant cools the second roller and then flows back into the cooling box through the outlet pipe, so as to realize the cooling of the second roller, and the second roller cools the embossing roller to realize the cooling of the embossing roller.
[0009] Optionally, the driving mechanism includes: A first bevel gear, which is arranged on the embossing roller; A second bevel gear, which is slidably arranged on the side pressing roller and rotates simultaneously with the side pressing roller; A driving member, which is used to drive the embossing roller to rotate; A moving assembly, which is used to adjust the position of the second bevel gear and make the second bevel gear mesh with the first bevel gear.
[0010] By adopting the above technical solution, the driving member drives the embossing roller to rotate, the rotation of the embossing roller drives the first bevel gear to rotate, and the rotation of the first bevel gear drives the second bevel gear and the side pressing roller to rotate, so as to realize the reverse rotation of the embossing roller and the side pressing roller. At the same time, through the design of the first bevel gear and the second bevel gear, the embossing roller and the side pressing roller can be adjusted according to actual needs, so that the synchronism of the embossing roller and the side pressing roller is better, thereby improving the printing effect on the paper.
[0011] At the same time, when embossing rollers and side pressing rollers of different sizes need to be synchronized, the moving assembly starts to drive the second bevel gear to move, so that the second bevel gear meshes with the first bevel gear for connection, so that the synchronism of the embossing roller and the side pressing roller is better and they can better adapt to embossing rollers and side pressing rollers of different sizes at the same time, improving the printing effect on the paper.
[0012] Optionally, the moving assembly includes: A moving ring, which is rotatably arranged on the second bevel gear; A moving member, which is arranged on the machine body and the piston rod is connected with the moving ring.
[0013] By adopting the above technical solution, the moving member drives the moving ring and the second bevel gear to move, so as to adjust the position of the second bevel gear.
[0014] Optionally, the cooling mechanism further includes a cooling assembly, the cooling assembly is arranged on the machine body and is located below the second roller, and the cooling assembly cools the outer surface of the second roller through a cooling medium and the cooling medium supports and positions the second roller under hydraulic action.
[0015] By adopting the above technical solution, the first roller body is located above the embossing roller. Therefore, the self-gravity of the first roller body can overcome the reaction force of the embossing roller, and the first roller body itself is not subject to other acting forces, thereby improving the supporting and positioning effect of the first roller body on the embossing roller. That is, even if the second roller body is designed to be hollow, it will not reduce the supporting and positioning effect of the first roller body on the embossing roller. However, the second roller body will be subject to its own gravity, the gravity of the side pressure roller, and the reaction force of the side pressure roller. Even the second roller body may also be subject to the gravity of both the embossing roller and the first roller body. Therefore, if the inside of the second roller body is designed as a hollow cooling cavity, it will greatly reduce the supporting and positioning effect of the second roller body on the side pressure roller and reduce the embossing effect on the paper.
[0016] By designing the second roller body as a solid structure, then cooling the outer surface of the second roller body through the cooling component, and then cooling the side pressure roller through the cooled outer surface of the second roller body, it is possible to greatly improve the cooling and temperature reduction effect on the side pressure roller. At the same time, with the solid structure of the second roller body, plus the hydraulic pressure generated by the cooling component to support the second roller body, thereby greatly improving the supporting force on the second roller body and improving the supporting and positioning effect of the second roller body on the side pressure roller. Therefore, the cooling component can simultaneously improve the cooling and temperature reduction effect and the supporting and positioning effect on the side pressure roller. Moreover, compared with contact support, liquid support greatly reduces the probability of wear generated during the support of the second roller body, further improving the supporting effect on the second roller body and improving the embossing effect on the paper.
[0017] Optionally, the cooling component includes: The cooling block is arranged along the axis of the second roller body, covers the entire second roller body and is located below the second roller body. A support surface that fits the second roller body and is used to support the second roller body is provided on the upper surface of the cooling block, and a receiving cavity for receiving the coolant is provided on the support surface; The first pipe body and the second pipe body are respectively arranged on the liquid inlet pipe and the liquid outlet pipe and are communicated with the receiving cavity. When the pump body is started, the coolant enters the receiving cavity and the coolant forms a hydraulic pressure to support the second roller body.
[0018] By adopting the above technical solution, the second roller body rotates and is supported on the support surface and contacts the coolant in the receiving cavity. When the pump body is started, the coolant enters the receiving cavity through the liquid inlet pipe and the first pipe body, so that the coolant in the receiving cavity cools the outer side wall of the second roller body and generates a hydraulic pressure to support the second roller body. Then the coolant flows back to the cooling tank through the second pipe body and the liquid outlet pipe, thereby realizing the cooling of the second roller body and the support of the second roller body. Thus, the coolant can simultaneously realize the cooling of the outer surface of the second roller body and liquid support, improve the supporting and positioning effect on the side pressure roller, and improve the embossing effect on the paper.
[0019] Optionally, an enlarged surface away from the second roller body is formed on the supporting surface. A sealing block is detachably arranged on the cooling block, and a sponge block pressing against the second roller body and the enlarged surface is detachably installed on the sealing block. The sponge block is used to remove the residual coolant on the second roller body and absorb the coolant leaking through the supporting surface.
[0020] By adopting the above technical solution, the sponge block absorbs and removes the residual coolant on the second roller body, greatly reducing the risk of the coolant contaminating the paper through the second roller body and the side pressure roller. At the same time, the sponge block can also absorb the coolant leaking through the supporting surface, reducing the probability of the coolant leaking into the external environment. Therefore, the embossing effect on the paper is further improved, and the risk of the coolant polluting the environment is reduced. Moreover, the sealing block can be removed regularly to recycle or replace the coolant on the sponge block, thereby improving the absorption effect of the sponge block on the coolant.
[0021] Optionally, detection mechanisms are arranged on both sides of the first roller body and the second roller body on the machine body. A plurality of the detection mechanisms are arranged at intervals along the axis of the embossing roller and support the embossing roller and the side pressure roller under the action of elastic force and are used to detect whether the embossing roller and the side pressure roller are deformed.
[0022] By adopting the above technical solution, the detection mechanism can be pressed against the embossing roller and the side pressure roller under the action of elastic force for support and positioning, thereby further improving the support and positioning effect on the embossing roller and the side pressure roller, reducing the risk of deformation of the embossing roller and the side pressure roller. At the same time, a plurality of detection mechanisms can detect the embossing roller and the side pressure roller at multiple different positions, and detect the surfaces of the two roller bodies of the embossing roller and the side pressure roller in real time, so as to know the conditions of the embossing roller and the side pressure roller faster and more directly. Therefore, when deformation problems occur in the embossing roller and the side pressure roller, they can be processed in time. Even when local deformation occurs in the embossing roller and the side pressure roller, information can be obtained in time for processing, and different processing methods can be carried out according to different deformation conditions, thereby further greatly improving the embossing effect on the paper.
[0023] Optionally, the detection mechanism includes: A mounting rod slidably arranged on the machine body along the direction close to or away from the embossing roller; A detection wheel rotatably arranged at one end of the mounting rod close to the embossing roller; A spring arranged on the machine body and connected to the mounting rod so that the detection wheel presses against the embossing roller for support and positioning; A detection component for detecting whether the embossing roller and the side pressure roller are deformed.
[0024] By adopting the above technical solution, the spring pushes the mounting rod and the detection wheel under the action of elastic force to press against the embossing roller, so as to achieve a certain supporting effect on the embossing roller. The rotation of the embossing roller drives the detection wheel to rotate. When the embossing roller is deformed, the detection component can detect and remind in time, so as to make timely treatment. At the same time, the side pressure roller is supported and detected in the same way, so as to further improve the embossing effect on the paper.
[0025] Optionally, the detection component includes: An inductor, arranged on the machine body; A moving rod, arranged at one end of the mounting rod close to the inductor and pressing against the inductor; when the embossing roller is deformed, the moving rod approaches or moves away from the inductor, and the inductor beeps an alarm after detecting that the pressure of the moving rod on the inductor changes and exceeds a specified range.
[0026] By adopting the above technical solution, the moving rod presses against the inductor. When the embossing roller is in a normal state, the inductor shows the pressure of the moving rod on the inductor. If the embossing roller is deformed, it can drive the moving rod to move, so that the pressure of the moving rod on the inductor changes. When the pressure value on the inductor exceeds a certain range, a beeping alarm is processed in time, so as to remind the staff to process the equipment in time, so as to realize the real-time detection of the deformation of the embossing roller and the side pressure roller.
[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. The first roller body and the second roller body are abutted against the embossing roller and the side pressure roller for support and positioning. The first roller body and the second roller body are made of metal, which can further improve the support effect on the embossing roller and the side pressure roller. At the same time, the cooling mechanism cools the first roller body and / or the second roller body, so as to realize the cooling of the embossing roller and / or the side pressure roller. Therefore, the risk of deformation of the embossing roller and the side pressure roller is greatly reduced. Coupled with the simultaneous rotation of the embossing roller and the side pressure roller, the risk of heat generation due to friction between the embossing roller and the side pressure roller and the paper is greatly reduced, and the risk of deformation of the embossing roller and the side pressure roller is further reduced. Therefore, the embossing quality of the paper is improved. BRIEF DESCRIPTION OF THE DRAWINGS

The driving mechanism 2 is used to drive the embossing roller 11 and the side pressing roller 12 to rotate simultaneously and in opposite directions. The embossing roller 11 and the side pressing roller 12 are used for embossing the paper. Both the first roller body 13 and the second roller body 14 are made of metal materials and respectively abut against the embossing roller 11 and the side pressing roller 12 for support and positioning. The cooling mechanism 4 is arranged on the body 1, and the cooling mechanism 4 is used to cool the first roller body 13 and / or the second roller body 14.
[0033] Referring to Figure 1 and Figure 2, the driving mechanism 2 includes a first bevel gear 21, a second bevel gear 22, a driving member 23 and a moving component 3. One end of the embossing roller 11 and the side pressing roller 12 in the same direction extends to the outside of the machine body 1. The first bevel gear 21 is key-connected to the embossing roller 11 and is located outside the machine body 1. The second bevel gear 22 is slidably sleeved on the side pressing roller 12 and is located outside the machine body 1. At the same time, the second bevel gear 22 and the side pressing roller 12 rotate simultaneously and synchronously. The second bevel gear 22 meshes with the first bevel gear 21. The driving member 23 is a motor. The output shaft of the driving member 23 is connected to the embossing roller 11 and drives the embossing roller 11 to rotate, so that the embossing roller 11 and the side pressing roller 12 rotate synchronously to emboss the paper.
[0034] The moving component 3 is used to adjust the position of the second bevel gear 22 and make the second bevel gear 22 mesh with the first bevel gear 21. The moving component 3 includes a moving ring 31 and a moving member 32. The moving ring 31 is coaxially and rotatably installed on the second bevel gear 22, and the moving member 32 is an electric push rod. The moving member 32 is fixedly installed on the machine body 1 and the piston rod is connected to the moving ring 31. When the moving member 32 is started, it drives the second bevel gear 22 to move, so that the second bevel gear 22 meshes with the first bevel gear 21; when the sizes of the embossing roller 11 and the side pressing roller 12 or the distance between them change, the moving member 32 starts the second bevel gear 22 to move, so that the second bevel gear 22 moves to continue meshing with the first bevel gear 21, so as to be able to adapt to different embossing rollers 11 and side pressing rollers 12 within a certain range and continue to be connected, so that the embossing roller 11 and the side pressing roller 12 can continue to rotate synchronously to emboss the paper.
[0035] Refer to Figure 1 , Figure 3 and Figure 4 , a cooling cavity 15 is coaxially opened in the first roller body 13. The second roller body 14 is a roller body with a solid structure. The cooling mechanism 4 includes a cooling box 41, a pump body 42, a liquid inlet pipe 43 and a liquid outlet pipe 44. The cooling box 41 is fixedly installed on the outer wall of the machine body 1 and is located below the second roller body 14. The cooling box 41 is filled with coolant.
[0036] Refer to Figure 3 and Figure 4 , the pump body 42 is fixedly installed on the upper surface of the cooling box 41 and is communicated with the inside of the cooling box 41. The liquid inlet pipe 43 is fixedly installed on the pump body 42 and extends vertically upward to one end of the first roller body 13, and the liquid inlet pipe 43 passes through the first roller body 13 and extends into the cooling cavity 15 and is rotatably connected to the first roller body 13. When the pump body 42 is started, the coolant enters the cooling cavity 15 through the liquid inlet pipe 43, so as to cool down the first roller body 13, and then the first roller body 13 cools down the embossing roller 11.
[0037] One end of the liquid outlet pipe 44 passes through the first roller 13 and the other end extends into the cooling chamber 15 and is rotatably connected to the first roller 13. At the same time, the other end of the liquid outlet pipe 44 extends downward to the upper surface of the cooling box 41. The liquid outlet pipe 44 is connected to the upper surface of the cooling box 41, so that the coolant in the cooling chamber 15 flows back into the cooling box 41.
[0038] Referring to Figure 1 , Figure 3 and Figure 4 , the cooling mechanism 4 further includes a cooling component 5. The cooling component 5 is arranged on the machine body 1 and is located below the second roller 14. The cooling component 5 cools the outer surface of the second roller 14 through a cooling medium and supports and positions the second roller 14 under the hydraulic action of the cooling medium. The cooling component 5 includes a cooling block 51, a first pipe body 52 and a second pipe body 53. The cooling block 51 is fixedly installed on the machine body 1 and is located below the second roller 14. A support surface 54 that fits the second roller 14 and supports the second roller 14 is formed on the upper surface of the cooling block 51. The support surface 54 covers the entire second roller 14 along the axis direction of the second roller 14. Expansion surfaces 55 that are inclined upward and away from the second roller 14 are formed on both sides of the support surface 54 along the axis of the second roller 14. A receiving cavity 56 is formed on the support surface 54.

At the same time, the first pipe body 52 and the second pipe body 53 are communicated with the inside of the receiving cavity 56, and the inner diameter of the second pipe body 53 is smaller than the inner diameter of the first pipe body 52. The coolant enters the receiving cavity 56 through the first pipe body 52 and then flows back into the liquid outlet pipe 44 through the second pipe body 53, so that a certain hydraulic pressure is formed in the receiving cavity 56. The hydraulic pressure can support the second roller 14, and at the same time, the coolant cools the second roller 14, so that the coolant can support and cool the second roller 14 at the same time.
[0040] Sealing blocks 57 are detachably installed on both opposite side walls of the cooling block 51 and on both sides of the receiving cavity 56. The length direction of the sealing blocks 57 is parallel to the axis direction of the second roller 14. A sponge block 58 is snap-fitted on the side wall of the sealing block 57 close to the second roller 14. The sponge block 58 presses against the second roller 14 and the expansion surface 55 for positioning, so that the sponge block 58 can remove the residual coolant on the second roller 14, and the sponge block 58 can also absorb the coolant leaked between the second roller 14 and the support surface 54. Thereby, the risk of the coolant moving to the paper can be reduced, and the probability of the coolant leaking into the external environment and being wasted can be reduced. At the same time, the coolant in the sponge block 58 can be recycled or the sponge block 58 can be replaced after the sealing block 57 is removed.
[0041] Referring toFigure 1 and Figure 5 On the machine body 1 and on one side of the first roller 13 and the second roller 14, a detection mechanism 6 is provided. A plurality of detection mechanisms 6 are arranged at intervals along the axis of the embossing roller 11 and support the embossing roller 11 and the side pressing roller 12 under the action of elastic force. The detection mechanism 6 can also be used to detect in real time whether the embossing roller 11 and the side pressing roller 12 are deformed; on the machine body 1, fixing plates 16 are arranged on both the upper and lower sides of the embossing roller 11 and the side pressing roller 12. The length direction of the fixing plate 16 is parallel to the axis of the embossing roller 11. On the machine body 1, mounting plates 17 are arranged on both sides of the two fixing rods away from the embossing roller 11 and the side pressing roller 12. The length directions of the mounting plate 17 and the fixing plate 16 are parallel. A plurality of detection mechanisms 6 are arranged on the two fixing plates 16 and the two mounting plates 17; the detection mechanisms 6 located at the embossing roller 11 and the side pressing roller 12 are arranged at intervals along the length direction of the fixing plate 16.

The detection wheel 62 is rotatably mounted at one end of the mounting rod 61 close to the embossing roller 11, and the axis of the detection wheel 62 is parallel to the axis of the embossing roller 11. One end of the spring 63 is fixedly mounted on the side wall of the mounting plate 17 close to the fixing plate 16, and the other end of the spring 63 is fixedly connected to the mounting rod 61. The spring 63 makes the detection wheel 62 press against the embossing roller 11 for support and positioning.

The sensor 71 is fixedly mounted on the side wall of the mounting plate 17 close to the fixing plate 16, and the sensor 71 is located inside the spring 63. The sensor 71 is electrically connected to the machine body 1 and transmits data to the inside of the machine body 1 for processing. A buzzer alarm is arranged on the machine body 1.
[0044] The moving rod 72 is fixedly mounted at one end of the mounting rod 61 close to the mounting plate 17, and the moving rod 72 presses against the sensor 71 for positioning. When the embossing roller 11 is in a normal state, the moving rod 72 has a certain initial pressure on the sensor 71. The sensor 71 transmits the detected pressure value data to the inside of the machine body 1 for display. When the pressure value of the moving rod 72 on the sensor 71 changes and exceeds the range, the buzzer alarm gives a buzzer alarm to remind the staff to pay attention to the equipment situation and process the equipment in time, thereby further improving the embossing treatment of the paper.
[0045] The working principle of the embodiment of the present application is as follows: The driving member 23 starts to drive the embossing roller 11 and the side pressing roller 12 to rotate synchronously to emboss the paper. At the same time, the pump body 42 starts to make the coolant enter the cooling cavity 15 to cool the first roller body 13. The first roller body 13 cools and supports the embossing roller 11. The coolant enters the accommodating cavity 56 to cool the second roller body 14 and the coolant generates hydraulic pressure to support the second roller body 14. The second roller body 14 can cool and support the side pressing roller 12, thereby further reducing the risk of deformation of the embossing roller 11 and the side pressing roller 12 and improving the embossing quality of the paper.
[0046] A plurality of detection wheels 62 are pressed against the embossing roller 11 and the side pressing roller 12 under the action of the spring 63 for support and positioning. At the same time, the moving rod 72 is pressed against the inductor 71 to detect the pressing force of the moving rod 72. When the pressing force changes and exceeds the specified range, a buzzer alarm is given to detect the deformation of the embossing roller 11 and the side pressing roller 12 in real time, so that the equipment can be processed better and earlier, thereby further improving the embossing quality of the paper.
