Description
Technical Field
[0001] This utility model relates to the field of embossing roller technology, and in particular to a water-cooled embossing roller. Background Technology
[0002] In the manufacturing processes of many industries such as packaging, building materials, leather, and paper, embossing is a crucial processing step. Its main function is to imprint specific textures or patterns onto the material surface using embossing rollers. To maintain the temperature stability of the embossing rollers, water-cooling structures have been incorporated into their design. However, the cooling process of embossing rollers still has the following shortcomings:
[0003] Traditional water-cooled embossing rollers often employ a simple cooling water channel design. The flow path of the coolant inside the roller is short and singular, and the contact area between the water channel and the roller is limited, resulting in insufficient heat transfer and low heat dissipation efficiency. This not only seriously affects the depth, clarity, and precision of the embossing, but also leads to quality problems such as blurred textures and shortened lifespan of the embossing roller.
[0004] An unreasonable coolant circulation path design may result in insufficient coolant flow or slow flow rate in some areas, thus affecting heat dissipation. At the same time, impurities and dirt are easily accumulated in the coolant during circulation, clogging the cooling channels. In addition, the complex assembly structure of the cooling water channel and embossing roller will increase the maintenance steps and costs of the cooling water channel. Utility Model Content
[0005] This utility model discloses a water-cooled embossing roller, including the steps of installing a spray pipe and a guide pipe. The operator installs the spray pipe inside the heat dissipation liner, securely connects the first guide pipe to the spray pipe to ensure that the two are connected and leak-free, connects the second guide pipe to the heat dissipation liner, and simultaneously allows one side of the first guide pipe and the second guide pipe to pass through the corresponding bearing. The spray nozzles of the spray pipe can spray coolant evenly.
[0006] In a first aspect, this disclosure provides a water-cooled embossing roller, specifically comprising: an embossing sleeve, the outer side of which is provided with a set of printing plates; a heat dissipation liner installed on the inner side of the embossing sleeve; a support shaft installed on each side of the heat dissipation liner with bolts; a set of sealing gaskets installed between the heat dissipation liner and the support shafts; a spray pipe installed on the inner side of the heat dissipation liner; a second drain pipe installed on one side of one of the support shafts, the second drain pipe having a bent structure; a first drain pipe installed on one side of the spray pipe; the first drain pipe communicating with the spray pipe; the second drain pipe communicating with the heat dissipation liner; and a set of bearings installed on the inner side of the support shafts.
[0007] Furthermore, a set of positioning strips is provided on the inner side of the embossed sleeve. The positioning strips have an arc structure, and a set of positioning grooves is opened on the outer side of the heat dissipation inner liner. The positioning grooves have an arc structure, and the positioning strips extend into the interior of the positioning grooves.
[0008] Furthermore, a heat dissipation liner is installed on the inner side of the embossed sleeve, and a set of evenly distributed buffer grooves are opened on the inner side of the heat dissipation liner.
[0009] Furthermore, a hidden groove is opened on each side of the heat dissipation inner liner. The hidden groove has a stepped structure. Two sealing gaskets are installed on the inner side of the hidden groove. A set of annular grooves is opened on each side of the sealing gasket. One side of the support shaft is installed inside the hidden groove. A set of stabilizing bolts is installed between one side of the support shaft and the heat dissipation inner liner.
[0010] Furthermore, a mounting hole is formed in the middle of the support shaft. The mounting hole has a cylindrical stepped structure. A set of bearings is installed on the inner side of the mounting hole, and the outer side of the bearing is in slight contact with the maximum inner diameter of the mounting hole.
[0011] Furthermore, one end of the spray pipe is sealed, and a set of evenly distributed spray holes are formed on the base of the spray pipe.
[0012] Furthermore, one side of the first drainage tube and the second drainage tube respectively passes through the interior of the bearing.
[0013] This utility model provides a water-cooled embossing roller, which has the following beneficial effects:
[0014] The arc-shaped positioning strip on the inner side of the embossed sleeve cooperates with the arc-shaped positioning groove on the outer side of the heat dissipation liner to achieve precise circumferential and axial positioning. This design not only improves installation efficiency and assembly accuracy, but also increases the contact area between the two and makes the connection tight. During equipment operation, it can effectively resist vibration and impact, prevent relative displacement and loosening, and ensure the reliability and stability of the equipment.
[0015] The stepped hidden grooves on both sides of the heat dissipation liner, the sealing gaskets, and the stabilizing bolts work together. The annular groove design of the sealing gasket increases the sealing area, effectively preventing media leakage and ensuring the sealing performance between the heat dissipation liner and the support shaft.
[0016] The evenly distributed buffer grooves on the inner side of the heat dissipation liner increase the heat dissipation area and improve heat dissipation efficiency. When the embossing sleeve generates heat during operation, the heat can be transferred to the heat dissipation liner more efficiently and dissipated through the buffer grooves. The coolant flows from the cooling pump through the first drain pipe into the spray pipe, and then flows back to the cooling pump through the second drain pipe. The above effects effectively reduce the temperature of the embossing sleeve and extend its service life. At the same time, the good heat dissipation performance helps maintain the stable working state of the embossing sleeve and improve the embossing quality. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0035] Example 1: Please refer to Figures 1 to 6 :
[0036] This utility model proposes a water-cooled embossing roller, including: an embossing sleeve 1, with a set of printing plates on the outer side of the embossing sleeve 1. The specific structure and shape of the printing plates are selected as needed. A heat dissipation liner 2 is installed on the inner side of the embossing sleeve 1. The material of the heat dissipation liner 2 is selected as a metal material with good heat dissipation effect in the prior art. A set of positioning strips with an arc structure are provided on the inner side of the embossing sleeve 1. A set of positioning grooves with an arc structure are opened on the outer side of the heat dissipation liner 2. The positioning strips extend into the interior of the positioning grooves. It is concluded that the arc positioning strips on the inner side of the embossing sleeve 1 cooperate with the arc positioning grooves on the outer side of the heat dissipation liner 2. The positioning strips extend into the grooves to achieve precise circumferential and axial positioning, improve installation efficiency and assembly accuracy. The arc structure makes the contact area between the positioning strips and the positioning grooves large and the connection tight, which can effectively resist vibration and impact during equipment operation, prevent relative displacement and loosening, and ensure equipment reliability.
[0037] In this embodiment of the disclosure, reference is made to Figures 1 to 6 As shown, a heat dissipation liner 2 is installed on the inner side of the embossed sleeve 1. A set of evenly distributed buffer grooves are opened on the inner side of the heat dissipation liner 2. The evenly distributed buffer grooves on the inner side of the heat dissipation liner 2 increase the heat dissipation area and improve the heat dissipation efficiency of the heat dissipation liner 2. When the embossed sleeve 1 generates heat during operation, the heat can be transferred to the heat dissipation liner 2 more efficiently and dissipated through the buffer grooves, reducing the temperature of the embossed sleeve 1 and extending the service life of the equipment. On the other hand, the precise positioning and good heat dissipation and buffering performance of the heat dissipation liner 2 help maintain the stable working state of the embossed sleeve 1.
[0038] In this embodiment of the disclosure, reference is made to Figures 1 to 6As shown, a support shaft 3 is installed on each side of the heat dissipation inner liner 2 with bolts. A set of sealing gaskets 4 is installed between the heat dissipation inner liner 2 and the support shaft 3. A hidden groove is opened on each side of the heat dissipation inner liner 2. The hidden groove has a stepped structure. Two sealing gaskets 4 are installed on the inner side of the hidden groove. A set of annular grooves is opened on each side of the sealing gasket 4. One side of the support shaft 3 is installed inside the hidden groove. A set of stabilizing bolts is installed between the one side of the support shaft 3 and the heat dissipation inner liner 2. First, the sealing gasket 4 in the stepped hidden groove of the heat dissipation inner liner 2 has an annular groove design to increase the sealing area, effectively prevent media leakage, and ensure the sealing performance between the heat dissipation inner liner 2 and the support shaft 3. Second, the stabilizing bolts tightly connect the support shaft 3 and the heat dissipation inner liner 2, ensuring that the heat dissipation inner liner 2 and the support shaft 3 can be assembled stably. The cooperation of the hidden groove, the sealing gasket 4 and the stabilizing bolts optimizes the connection structure between the heat dissipation inner liner 2 and the support shaft 3, and improves the stability of heat dissipation inside the embossed sleeve 1 and the stability of its own rotation.
[0039] In this embodiment of the disclosure, reference is made to Figures 1 to 6 As shown, a spray pipe 5 is installed on the inner side of the heat dissipation liner 2. A second drain pipe 6 is installed on one side of one of the support shafts 3. The second drain pipe 6 has a bent structure. A first drain pipe 501 is installed on one side of the spray pipe 5. The first drain pipe 501 is connected to the spray pipe 5. The second drain pipe 6 is connected to the heat dissipation liner 2. One end of the spray pipe 5 has a sealed structure. A set of evenly distributed spray holes are opened on the spray pipe 5. It can be concluded that the coolant driven by the cooling pump enters the spray pipe 5 through the first drain pipe 501 and is sprayed out from the evenly distributed spray holes. It can be sprayed all over and evenly onto the inner side of the heat dissipation liner 2. Combined with the structure of the heat dissipation liner 2 itself, the coolant can efficiently remove the heat of the heat dissipation liner 2 and the embossed sleeve 1, improve the cooling effect and water cooling uniformity of the embossed sleeve 1. Finally, the coolant flows back to the interior of the cooling pump through the second drain pipe 6 for cooling again.
[0040] In this embodiment of the disclosure, reference is made to Figures 1 to 6 As shown, a set of bearings 7 are installed on the inner side of the support shaft 3. The specific structure and model of the bearings 7 are selected according to the inner diameter of the support shaft 3. A mounting hole is opened in the middle of the support shaft 3. The mounting hole has a cylindrical stepped structure. A set of bearings 7 are installed on the inner side of the mounting hole. The outer side of the bearing 7 is in slight contact with the maximum inner diameter of the mounting hole. Therefore, the bearing 7 can be accurately installed and positioned after being installed inside the mounting hole, ensuring the installation accuracy of the bearing 7. One side of the first drain pipe 501 and the second drain pipe 6 pass through the interior of the bearing 7. The specific structure of the bearing 7 is selected as needed. Referring to the positioning structure of the bearing 7 and the rotating shaft in the prior art, it is concluded that the function of the bearing 7 is to keep the first drain pipe 501 and the second drain pipe 6 in a stable state when the embossed sleeve 1 rotates. The drain pipe cooperates with the bearing 7 and does not affect the circulation of coolant between the spray pipe 5 and the heat dissipation tank 2.
[0041] Example 2, based on Example 1, with reference to Figures 1 to 6 As shown, one side of the first drain pipe 501 needs to be securely connected to the outlet of the cooling pump in accordance with existing technology, and one side of the second drain pipe 6 needs to be securely connected to the inlet of the cooling pump in accordance with existing technology, so as to control the cooling pump in the existing technology to deliver coolant to the inside of the first drain pipe 501.
[0042] Example 3, based on Example 1, with reference to Figures 1 to 6 As shown, the embossing sleeve 1, heat dissipation inner liner 2, support shaft 3, sealing gasket 4, spray pipe 5, first drainage pipe 501, second drainage pipe 6, and bearing 7 work together to form a water-cooled embossing roller. A set of positioning rings is provided on the outer side of the support shaft 3, and the secondary material of the support shaft 3 is selected from the wear-resistant materials in the existing technology.
[0043] The working principle of this embodiment:
[0044] First, based on the inner diameter of the support shaft 3, the staff selects a bearing 7 with a suitable structure and model, checks the rotational flexibility of the bearing 7, and prepares the necessary tools for installation, such as wrenches, screwdrivers, and hoisting equipment.
[0045] The assembly steps of the embossing roller are as follows: the worker installs the heat dissipation inner liner 2 into the inside of the embossing sleeve 1, aligns the positioning groove on the outside of the heat dissipation inner liner 2 with the positioning strip of the embossing sleeve 1, and extends the positioning strip into the inside of the positioning groove to achieve precise circumferential and axial positioning.
[0046] The steps for installing the support shaft 3 and the sealing gasket 4 are as follows: the worker applies an appropriate amount of sealant to the inside of the hidden grooves on both sides of the heat dissipation liner 2, then installs the sealing gasket 4 into the hidden groove, aligns one side of the support shaft 3 with the hidden groove, slowly inserts it, and uses a stabilizing bolt to tightly connect the support shaft 3 to the heat dissipation liner 2. Tighten the bolt to the specified torque to ensure a stable connection.
[0047] The steps for installing bearing 7 onto support shaft 3 are as follows: the worker applies a small amount of lubricating oil into the cylindrical stepped structure mounting hole in the middle of support shaft 3, and then carefully installs bearing 7 into the mounting hole, so that the outer side of bearing 7 makes slight contact with the maximum inner diameter of the mounting hole.
[0048] The steps for installing the spray pipe 5 and the drain pipe are as follows: The worker installs the spray pipe 5 inside the heat dissipation liner 2, ensuring that its position is correct, and firmly connects the first drain pipe 501 to the spray pipe 5, ensuring that the two are connected and leak-free. The worker then connects the second drain pipe 6 to the heat dissipation liner 2, and at the same time, makes one side of the first drain pipe 501 and the second drain pipe 6 pass through the corresponding bearing 7 respectively.
[0049] In the process of connecting the cooling pump, the staff referred to the existing technology and firmly connected one side of the first drain pipe 501 to the outlet of the cooling pump. They used a suitable sealant to ensure a good seal at the connection point. Similarly, they firmly connected one side of the second drain pipe 6 to the inlet of the cooling pump to ensure that the coolant could circulate smoothly.
[0050] The staff started the cooling pump to circulate the coolant in the system and checked whether the flow rate and pressure of the coolant were normal. This step still refers to the existing technology. They observed whether the spray nozzle of the spray pipe 5 could spray the coolant evenly and whether the coolant could be sprayed evenly and comprehensively onto the inner side of the heat dissipation tank 2.
