Description

Technical Field

[0001] This utility model relates to the technical field of water transfer printing paper production equipment, and in particular to a high-precision adjustment device and coating machine for coating water transfer printing paper. Background Technology

[0002] Coating machines play a crucial role in the water transfer printing process, serving as essential equipment for applying adhesive to water transfer paper.

[0003] Generally, a coating line for a coating machine typically consists of multiple glue rollers and glue tanks, covering the feeding, coating, drying, and winding processes of water transfer paper. In the coating stage, the glue rollers first carry the water transfer paper through the glue tank, immersing it in the glue and achieving initial glue application. Then, the initially glued water transfer paper needs to pass through the glue gap between two adjusting rollers on the coating line to control the glue thickness. However, traditional coating machines often suffer from poor adjustment precision when adjusting the glue gap, making it difficult to ensure the coating quality of the water transfer paper. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-precision adjustment device and coating machine for water transfer paper coating that can achieve high-precision adjustment of the coating thickness of water transfer paper, thereby effectively ensuring the coating quality of water transfer paper.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A high-precision adjustment device for coating adhesive on water transfer printing paper includes:

[0007] A fixed base is installed on the frame of the coating machine;

[0008] The adjustment mechanism includes a fine-tuning screw and a pressure sensor; one end of the fine-tuning screw is movably connected to the fixed base, and the pressure sensor is fixedly installed on the rotating frame of the coating machine. When the rotating frame rotates forward around a preset central axis, the sensing end of the pressure sensor approaches or abuts against the other end of the fine-tuning screw. When the rotating frame rotates in the opposite direction around the preset central axis, the sensing end of the pressure sensor moves away from the other end of the fine-tuning screw.

[0009] The rotating frame is used to drive the first adjusting roller to move closer to or away from the second adjusting roller on the frame, and a glue application gap is formed between the first adjusting roller and the second adjusting roller.

[0010] In one embodiment, the fixing seat has an internal threaded hole that matches the external thread at one end of the fine-tuning screw, and one end of the fine-tuning screw passes through the internal threaded hole.

[0011] In one embodiment, the mounting base is detachably connected to the frame; and / or,

[0012] The pressure sensor is detachably connected to the rotating frame.

[0013] In one embodiment, the adjusting mechanism further includes a limiting threaded sleeve, which is threaded onto one end of the fine-tuning screw.

[0014] In one embodiment, the mounting base is a one-piece molded structure.

[0015] In one embodiment, the other end of the fine-tuning screw is provided with a rotating part and an abutting part in sequence. The rotating part is used to match the opening of the movable wrench, and the end of the abutting part is used to abut against the sensing end of the pressure sensor.

[0016] A coating machine includes a rotating frame, a machine frame, a first adjusting roller, a second adjusting roller, and a high-precision adjusting device for coating water transfer paper as described in any of the above embodiments;

[0017] One end of the rotating frame is rotatably connected to the machine frame, and the other end of the rotating frame is rotatably connected to the first adjusting rubber roller. A second adjusting rubber roller is rotatably mounted on the machine frame. A glue application gap is formed between the first adjusting rubber roller and the second adjusting rubber roller. The rotating frame is used to drive the first adjusting rubber roller to move closer to or away from the second adjusting rubber roller.

[0018] In one embodiment, the coating machine further includes a hydraulic transmission mechanism built into the frame, the hydraulic transmission mechanism being used to drive one end of the rotating frame to rotate around the preset central axis.

[0019] Compared with the prior art, the present invention has at least the following advantages:

[0020] When the rotating frame drives the first adjusting roller to approach or move away from the second adjusting roller on the frame, that is, when the rotating frame rotates forward or backward around the preset central axis, the rotating frame will simultaneously drive the sensing end of the pressure sensor to abut or move away from the other end of the fine-tuning screw. At the same time, since one end of the fine-tuning screw is movably connected to the fixed base, the distance between the other end of the fine-tuning screw and the sensing end of the pressure sensor can be adjusted, and the fine-tuning screw can be adjusted accordingly based on the pressure value of the pressure sensor. This enables high-precision adjustment of the coating gap, thereby effectively ensuring the coating quality of the water transfer printing paper. Attached Figure Description

[0028] This disclosure provides a high-precision adjustment device for coating water transfer printing paper, including a fixed base and an adjustment mechanism. The fixed base is mounted on the frame of a coating machine; the adjustment mechanism includes a fine-tuning screw and a pressure sensor; one end of the fine-tuning screw is movably connected to the fixed base, and the pressure sensor is fixedly mounted on the rotating frame of the coating machine. When the rotating frame rotates forward around a preset central axis, the sensing end of the pressure sensor approaches or abuts against the other end of the fine-tuning screw; when the rotating frame rotates in the opposite direction around the preset central axis, the sensing end of the pressure sensor moves away from the other end of the fine-tuning screw. The rotating frame drives a first adjusting roller to approach or move away from a second adjusting roller on the frame, and a coating gap is formed between the first adjusting roller and the second adjusting roller.

[0029] Please see Figures 1 to 2 To better understand the high-precision adjustment device 10 for water transfer paper coating of this application, the following further explanation of the high-precision adjustment device 10 for water transfer paper coating is provided:

[0030] One embodiment of the high-precision adjustment device 10 for coating water transfer paper includes a fixed base 100 and an adjustment mechanism 200. The fixed base 100 is mounted on the frame 400 of the coating machine; the adjustment mechanism 200 includes a fine-tuning screw 210 and a pressure sensor 220; one end of the fine-tuning screw 210 is movably connected to the fixed base 100, and the pressure sensor 220 is fixedly mounted on the rotating frame 300 of the coating machine. When the rotating frame 300 rotates forward around a preset central axis, the sensing end of the pressure sensor 220 approaches or abuts against the other end of the fine-tuning screw 210. When the rotating frame 300 rotates in the opposite direction around the preset central axis, the sensing end of the pressure sensor 220 moves away from the other end of the fine-tuning screw 210. The rotating frame 300 is used to drive the first adjusting roller 500 to approach or move away from the second adjusting roller 600 on the frame 400, and a coating gap 501 is formed between the first adjusting roller 500 and the second adjusting roller 600.

[0031] In this embodiment, when the rotating frame 300 drives the first adjusting roller 500 to approach or move away from the second adjusting roller 600 on the frame 400, that is, when the rotating frame 300 rotates forward or backward around the preset central axis, the rotating frame 300 will simultaneously drive the sensing end of the pressure sensor 220 to abut or move away from the other end of the fine adjustment screw 210. At the same time, since one end of the fine adjustment screw 210 is movably connected to the fixed base 100, the distance between the other end of the fine adjustment screw 210 and the sensing end of the pressure sensor 220 can be adjusted, and the fine adjustment screw 210 can be adjusted accordingly according to the pressure value of the pressure sensor 220, thereby achieving high-precision adjustment of the coating gap 501, and effectively ensuring the coating quality of the water transfer paper.

[0032] like Figure 2 As shown, in one embodiment, the fixing seat 100 has an internal threaded hole 101, which matches the external thread of one end of the fine adjustment screw 210, and one end of the fine adjustment screw 210 passes through the internal threaded hole 101.

[0033] It is understood that in this embodiment, when the rotating frame 300 rotates forward around the preset central axis, and the sensing end of the pressure sensor 220 approaches the other end of the fine adjustment screw 210, that is, when the sensing end of the pressure sensor 220 has not yet come into contact with the other end of the fine adjustment screw 210, the process of the first adjusting roller 500 approaching the second adjusting roller 600 at this time belongs to the coarse adjustment stage of the glue application gap 501; when the sensing end of the pressure sensor 220 comes into contact with the other end of the fine adjustment screw 210, the process of the first adjusting roller 500 continuously approaching the second adjusting roller 600 at this time belongs to the fine adjustment stage of the glue application gap 501. Specifically, by finely rotating one end of the fine-tuning screw 210 relative to the fixed base 100, the distance between the other end of the fine-tuning screw 210 and the sensing end of the pressure sensor 220 is adjusted. This allows the size of the coating gap 501 to be adjusted according to the pressure value of the pressure sensor 220, thereby achieving high-precision adjustment of the coating gap 501. This enables the high-precision adjustment device 10 for water transfer paper coating to adapt to the technical requirements of coating thickness for different specifications of water transfer paper and effectively ensure the coating quality of water transfer paper.

[0034] It should be noted that, as Figure 1 As shown, the central axis around which the bidirectional arrow X is surrounded is the preset central axis in this embodiment.

[0035] like Figure 1 and Figure 2 As shown, in one embodiment, the mounting base 100 is detachably connected to the frame 400. This facilitates the assembly and disassembly of the mounting base 100 for adjustment. Specifically, the mounting base 100 and the frame 400 are connected by screws.

[0036] like Figure 1 and Figure 2 As shown, in one embodiment, the pressure sensor 220 is detachably connected to the rotating frame 300. This facilitates the disassembly, assembly, and maintenance of the pressure sensor 220. Specifically, the pressure sensor 220 is screwed to the rotating frame 300.

[0037] like Figure 1 and Figure 2 As shown, in one embodiment, the adjustment mechanism 200 further includes a limiting threaded sleeve 230, which is threaded onto one end of the fine-tuning screw 210. Thus, by tightening the limiting threaded sleeve 230, the fine-tuning screw 210 can be firmly fixed in place to prevent loosening and displacement, thereby effectively ensuring the positional accuracy of the fine-tuning screw 210 after the high-precision adjustment stage of the adhesive application gap 501 is completed.

[0038] like Figure 1 and Figure 2 As shown, in one embodiment, the fixing base 100 is a one-piece molded structure. This gives the fixing base 100 better structural strength.

[0039] like Figure 1 and Figure 2 As shown, in one embodiment, the other end of the fine-tuning screw 210 is provided with a rotating part 2110 and an abutting part 2120 in sequence. The rotating part 2110 is used to match the mouth of the movable wrench, and the end of the abutting part 2120 is used to abut against the sensing end of the pressure sensor 220.

[0040] It is understandable that during the high-precision adjustment stage of the glue application gap 501, the user can use the wrench to rotate the fine adjustment screw 210, thereby improving the convenience and practicality of adjusting the fine adjustment screw 210.

[0041] This application also provides a coating machine, including a rotating frame 300, a machine frame 400, a first adjusting roller 500, a second adjusting roller 600, and a high-precision adjusting device 10 for coating water transfer paper as described in any of the above embodiments; one end of the rotating frame 300 is rotatably connected to the machine frame 400, and the other end of the rotating frame 300 is rotatably connected to the first adjusting roller 500; the second adjusting roller 600 is rotatably mounted on the machine frame 400; a coating gap 501 is formed between the first adjusting roller 500 and the second adjusting roller 600; the rotating frame 300 is used to drive the first adjusting roller 500 to move closer to or away from the second adjusting roller 600.

[0042] In this embodiment, when the rotating frame 300 drives the first adjusting roller 500 to approach or move away from the second adjusting roller 600 on the frame 400, that is, when the rotating frame 300 rotates forward or backward around the preset central axis, the rotating frame 300 will simultaneously drive the sensing end of the pressure sensor 220 to abut or move away from the other end of the fine adjustment screw 210. At the same time, since one end of the fine adjustment screw 210 is movably connected to the fixed base 100, the distance between the other end of the fine adjustment screw 210 and the sensing end of the pressure sensor 220 can be adjusted, and the fine adjustment screw 210 can be adjusted accordingly according to the pressure value of the pressure sensor 220, thereby achieving high-precision adjustment of the coating gap 501, and effectively ensuring the coating quality of the water transfer paper.

[0043] like Figure 1 As shown, in one embodiment, the coating machine further includes a hydraulic transmission mechanism (not shown), which is built into the frame 400 and is used to drive one end of the rotating frame 300 to rotate around the preset central axis.

[0044] It is understood that in this embodiment, the hydraulic transmission mechanism can provide a reliable driving force to the rotating frame 300, so as to effectively ensure the smoothness of the rotation of one end of the rotating frame 300 around the preset central axis, thereby ensuring the high-precision adjustment of the adhesive application gap 501.

[0045] Compared with the prior art, the present invention has at least the following advantages:

[0046] When the rotating frame drives the first adjusting roller to approach or move away from the second adjusting roller on the frame, that is, when the rotating frame rotates forward or backward around the preset central axis, the rotating frame will simultaneously drive the sensing end of the pressure sensor to abut or move away from the other end of the fine-tuning screw. At the same time, since one end of the fine-tuning screw is movably connected to the fixed base, the distance between the other end of the fine-tuning screw and the sensing end of the pressure sensor can be adjusted, and the fine-tuning screw can be adjusted accordingly based on the pressure value of the pressure sensor. This enables high-precision adjustment of the coating gap, thereby effectively ensuring the coating quality of the water transfer printing paper.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
