Description

Technical Field

[0001] The present application belongs to the technical field of release paper rehumidification equipment, and in particular relates to a rehumidification device for release paper production. Background Art

[0002] Release paper, also known as silicone paper or anti-stick paper, primarily serves to separate sticky objects, such as tape. It typically needs to be peeled off and discarded after use. It's widely used as a carrier for tape and other adhesive products, though it also has applications in the food and medical industries.

[0003] An existing Chinese patent, publication number CN106245436B, discloses a superheated steam release paper rewetting device with an electrostatic field and its manufacturing process. The device comprises a housing with a paper passageway in the middle for the release paper to pass through. This passageway divides the housing into two independent steam injection chambers. A rewetting zone is located on either side of the passageway between the two steam injection chambers. Each steam injection chamber comprises a low-pressure steam zone, a high-pressure superheated steam zone, a guide zone, and a steam source control mechanism. The guide zone is equipped with a steam injection pipe connected to the rewetting zone. A steam-water separator is located at the bottom of the housing, connected to the high-pressure superheated steam zone. Guide rollers for guiding the release paper are located at the bottom and top of the housing, respectively. A high-voltage electric field generating zone is located on the guide rollers at the bottom entrance of the housing.

[0004] Although the above-mentioned release paper rewetting equipment improves the stability and uniformity of the release paper rewetting, in order to ensure that the release paper can be completely rewetted, the range of steam sprayed from the steam injection pipe must be larger than the width of the release paper. Excess steam will be sprayed onto the inner wall of the paper threading channel to form water droplets. When the water droplets slide down, they may drip onto the release paper. Improvements are made to this problem. Utility Model Content

[0005] The purpose of this application is to address the above-mentioned technical problems and provide a rewetting device for release paper production, which can be used to collect water droplets on the inner wall surface of the paper threading channel and reduce the impact of water droplets on the release paper.

[0006] The present application provides a rehumidification device for release paper production, comprising:

[0007] The shell includes a paper threading channel, a low-pressure steam zone, a high-pressure superheated steam zone, and a steam injection pipe;

[0008] A recovery mechanism is installed on the housing, and includes a plurality of first recovery ports and a second recovery port;

[0009] a recovery chamber mounted on the shell;

[0010] A connecting channel connected between the first recovery port, the second recovery port and the recovery chamber;

[0011] Among them, the first recovery port is placed on the inner wall surface of the paper threading channel, the first recovery port is distributed on the lower side of the steam injection pipe, and the second recovery port is placed on the inner wall surface of the paper threading channel and relative to the width direction of the paper.

[0012] The release paper passes through the paper penetration channel, and steam is ejected from several steam injection pipes. The high-pressure superheated steam zone is placed above the steam injection pipe. The temperature of the position of the paper penetration channel corresponding to the high-pressure superheated steam zone is relatively high, and it is not easy to condense water droplets. After the steam is ejected from the steam injection pipe, most of it flows downward. A small amount of water vapor that is not combined with the release paper contacts the inner wall surface of the paper penetration channel below the steam injection pipe, and condenses into water droplets when it is cold. The water droplets are recovered by the recovery mechanism. When the water droplets slide downward, they pass through the first recovery port and the second recovery port, flow into the first recovery port and the second recovery port, and flow into the recovery chamber through the connecting channel. The water droplets in the paper penetration channel are collected through the first recovery port and the second recovery port to prevent the water droplets from dripping from the shell and reduce the impact of the water droplets on the release paper. The steam is ejected from the steam injection pipe by setting a steam source control mechanism.

[0013] Furthermore, the recovery mechanism is provided with a guide surface, and the guide surface is placed at the upper opening position of the first recovery port and the second recovery port.

[0014] The guiding surface facilitates guiding the water droplets on the inner wall of the paper threading channel into the first recovery port and the second recovery port, thereby improving the drainage effect of the water droplets and further improving the recovery rate of the water droplets.

[0015] Furthermore, the recovery chamber is provided with a negative pressure device.

[0016] The recovery chamber is connected to a negative pressure device to increase the flow rate of the collected water droplets in the connecting channel, thereby further improving the recovery efficiency of the water droplets.

[0017] Furthermore, the recycling mechanism includes:

[0018] The installation slot is connected to the first recovery port and the second recovery port;

[0019] The sponge body is installed in the installation groove;

[0020] Wherein, the mounting groove is connected to the guide surface.

[0021] By setting installation grooves and sponges at the first recovery port and the second recovery port, when the water droplets are collected through the first recovery port and the second recovery port, the water droplets come into contact with the sponge, and are quickly absorbed by the water absorption properties of the sponge. Then, they flow in the connecting channel under the action of the negative pressure device, thereby further improving the recovery efficiency of the water droplets.

[0022] Furthermore, the housing includes:

[0023] An adjusting block is movably mounted on the housing and is placed on the inner wall of the paper threading passage in a width direction relative to the paper;

[0024] Adjusting rack, mounted on the adjusting block;

[0025] an adjusting gear mounted on the housing and meshing with the adjusting rack;

[0026] Wherein, the second recovery port is placed on the regulating block.

[0027] When the width of the release paper passing through the paper threading channel changes, the adjustment block is used to adjust the corresponding steam injection pipe to be opened or blocked, so as to control the change of the steam injection range to adapt it to the width of the release paper and improve the utilization rate of the steam. The movement of the adjustment block is achieved by adjusting the gear and the rack structure. The adjustment gear is rotated by other driving devices or manually, and the second recovery port is placed on the adjustment block and moves simultaneously with the adjustment block.

[0028] Furthermore, guide parts are provided on both sides of the regulating block, and the guide parts are connected to the second recovery port.

[0029] The guide parts are placed on both sides of the adjustment block and connected to the second recovery port. When the water droplets slide through the angle between the adjustment block and the paper feeding channel, the water droplets are guided into the second recovery port by the guide parts. The guide parts are placed at the lower opening of the second recovery port.

[0030] The beneficial effects of this application are:

[0031] 1. The condensed water droplets in the paper threading channel are recovered by the recovery mechanism. When the water droplets slide down, they pass through the first recovery port and the second recovery port, flow into the first recovery port and the second recovery port, and then flow into the recovery chamber through the connecting channel for collection, thereby reducing the impact of water droplets dripping from the shell on the release paper.

[0032] 2. Improve the drainage effect of water droplets through the guiding surface, and further improve the recovery rate of water droplets.

[0033] 3. Improve the water droplet recovery efficiency through negative pressure device and sponge. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0041] The following provides a detailed description of the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0042] Example 1:

[0043] like Figures 1-4 As shown, the embodiment of the present application provides a rehumidification device for release paper production, comprising:

[0044] The housing 100 includes a paper passage 110, a low-pressure steam zone 120, a high-pressure superheated steam zone 130, and a steam injection pipe 140;

[0045] The recovery mechanism 200 is installed on the housing 100 and includes a plurality of first recovery ports 210 and a second recovery port 220;

[0046] The recovery chamber 300 is mounted on the housing 100;

[0047] The connecting channel 400 is connected between the first recovery port 210, the second recovery port 220 and the recovery chamber 300;

[0048] The first recovery port 210 is located on the inner wall of the paper threading channel 110 and is distributed on the lower side of the steam injection pipe 140 . The second recovery port 220 is located on the inner wall of the paper threading channel 110 and is in the width direction of the paper.

[0049] The release paper passes through the paper threading channel 110, and steam is ejected from several steam injection pipes 140. The high-pressure superheated steam zone 130 is located above the steam injection pipe 140. The temperature of the position of the paper threading channel 110 corresponding to the high-pressure superheated steam zone 130 is relatively high, and it is not easy to condense water droplets. After the steam is ejected from the steam injection pipe 140, most of it flows downward. A small amount of water vapor that is not combined with the release paper contacts the inner wall of the paper threading channel 110 below the steam injection pipe 140, and condenses into water droplets when it is cooled. The water droplets are then recycled through the recycling machine. The structure 200 facilitates the recovery of water droplets. When the water droplets slide downward and pass through the first recovery port 210 and the second recovery port 220, they flow into the first recovery port 210 and the second recovery port 220 and flow into the recovery chamber 300 through the connecting channel 400. The water droplets in the paper threading channel 110 are collected through the first recovery port 210 and the second recovery port 220 to prevent the water droplets from dripping from the shell 100 and reduce the impact of the water droplets on the release paper. Steam is sprayed out from the steam injection pipe 140 by setting a steam source control mechanism.

[0050] Example 2:

[0051] like Figure 2 、 Figure 3 As shown, an embodiment of the present application provides a rehumidification device for release paper production. In addition to the above-mentioned technical features, the recovery mechanism 200 is further provided with a guide surface 211, and the guide surface 211 is placed at the upper opening position of the first recovery port 210 and the second recovery port 220.

[0052] The guiding surface 211 facilitates guiding the water droplets on the inner wall of the paper threading channel 110 into the first recovery port 210 and the second recovery port 220 , thereby improving the drainage effect of the water droplets and further improving the recovery rate of the water droplets.

[0053] Furthermore, the recovery chamber 300 is provided with a negative pressure device 500 .

[0054] The recovery chamber 300 is connected to the negative pressure device 500 to increase the flow rate of the collected water droplets in the connecting channel 400, thereby further improving the recovery efficiency of the water droplets.

[0055] Furthermore, the recycling mechanism 200 includes:

[0056] The mounting groove 212 is connected to the first recovery port 210 and the second recovery port 220;

[0057] The sponge 213 is installed in the installation groove 212;

[0058] The mounting groove 212 is connected to the guide surface 211 .

[0059] By setting the installation groove 212 and the sponge 213 at the first recovery port 210 and the second recovery port 220, when the water droplets are collected through the first recovery port 210 and the second recovery port 220, the water droplets come into contact with the sponge 213, and the water droplets are quickly absorbed by the water absorption characteristics of the sponge 213, and then flow in the connecting channel 400 under the action of the negative pressure device 500, thereby further improving the recovery efficiency of the water droplets.

[0063] An adjustment rack 610 is mounted on the adjustment block 600;

[0064] An adjusting gear 620 is mounted on the housing 100 and meshes with the adjusting rack 610;

[0065] The second recovery port 220 is placed on the adjustment block 600 .

[0066] When the width of the release paper passing through the paper threading channel 110 changes, the adjustment block 600 is used to control the corresponding steam injection pipe 140 to be opened or blocked, so as to control the change of the steam injection range to make it adapt to the width of the release paper and improve the utilization rate of the steam. The movement of the adjustment block 600 is achieved by adjusting the structure of the gear 620 and the rack 610. The adjustment gear 620 is rotated by other driving devices or manually, and the second recovery port 220 is placed on the adjustment block 600 and moves simultaneously with the adjustment block 600.

[0067] Furthermore, guide portions 221 are provided on both sides of the regulating block 600 , and the guide portions 221 are connected to the second recovery port 220 .

[0068] The guide part 221 is placed on both sides of the adjustment block 600 and is connected to the second recovery port 220. When the water droplets slide through the angle between the adjustment block 600 and the paper threading channel 110, the water droplets are guided by the guide part 221 to the second recovery port 220. The guide part 221 is placed at the lower opening of the second recovery port 220.
