When the top of the breathable medical dressing that is coated with glue between the heating pressure roller and the glue coating roller and transported to the surface of the winding mechanism is squeezed and contacted with the bottom of the circulating cooling mechanism, the water inside the top of the circulating cooling mechanism will absorb a large amount of heat, causing partial slow evaporation. The evaporated gas will form air pressure and push the cooling water at the bottom of the circulating cooling mechanism to enter the top for replenishment. Finally, through the circulation of cold water, the top surface of the breathable medical dressing can be cooled to avoid overheating that affects the subsequent taking efficiency.

[0022] The present invention arranges a lifting component, and the bottom part of the lifting component absorbs the heat of the bottom of the circulating cooling mechanism, causing the internal gas of this part to expand due to the heat, which will smoothly push the internal part of the bottom cooling mechanism to extend. When the bottom of the lifting component is restored, the two end parts will pull the internal part of the bottom cooling mechanism to reset downward, and then it can be stored in the internal shell of the bottom cooling mechanism for protection, avoiding pollution from external dust and impurities when not in working state.

[0023] The present invention provides a bottom cooling mechanism and a driving assembly. When the water flow at the bottom of the circulating cooling mechanism continuously fills the inner cavity at the top of the circulating cooling mechanism, the driving assembly as a whole is driven to rotate. When the inner part of the bottom cooling mechanism is extended, the bottom of one side of the extended part is connected with the top part of the driving assembly. Therefore, the inner part of the bottom cooling mechanism can be driven to rotate by the overall rotation of the driving assembly, so as to cool the glue-coated surface of the dressing. While improving the cooling efficiency, the cooling speed of the water at the top of the circulating cooling mechanism is accelerated, thereby improving the cooling quality.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 8 As shown, the present invention provides a breathable medical dressing gluing device, including a gluing machine body 1; a winding mechanism 2, which is arranged in the middle of one side of the gluing machine body 1; a heating pressure roller 3, which is arranged in the middle of the gluing machine body 1 and is located above the winding mechanism 2; a circulating cooling mechanism 7, including a water storage roller 701, the water storage roller 701 is fixedly installed on the inner side of the gluing machine body 1, and is located between the winding mechanism 2 and the heating pressure roller 3, the middle of the top end of the water storage roller 701 is fixedly connected with a water pipe connecting to an air box 702, one end of the water pipe connecting to the air box 702 is fixedly connected to one end of the water storage roller 701 through a cooling water pipe 703, an air inlet valve 704 is arranged inside one end of the top of the cooling water pipe 703, and a water inlet valve 705 is arranged inside the other end of the cooling water pipe 703.

[0035] When the water inside the water storage roller 701 absorbs the heat from the top surface of the breathable medical dressing that is attached to the bottom, the water inside will slowly evaporate into gas, and the gas will enter the cooling water pipe 703 through the air inlet valve 704. Then, the air pressure will push the water inside the cooling water pipe 703 through the water inlet valve 705 into the water storage roller 701 for replenishment, thereby achieving the purpose of circulating water cooling.

[0036] like Figure 2 As shown, a reeling mechanism 4 is provided on the top of the other side of the glue coating machine body 1 .

[0037] With the above solution, the user can place the breathable medical dressing to be coated with glue on the surface of the unwinding mechanism 4, and then the unwinding mechanism 4 can be rotated to smoothly unwind and transport it to the glue coating position.

[0038] like Figure 2 As shown, a glue coating roller 5 located below the heating and pressing roller 3 is arranged on the inner side of the glue coating machine body 1 , and a glue storage frame 6 located below the glue coating roller 5 is arranged on the inner side of the glue coating machine body 1 .

[0039] The above scheme is adopted: by providing a glue storage frame 6, by placing the glue to be applied inside the glue storage frame 6 for storage, the glue inside can be taken away by the subsequent rotation of the glue coating roller 5, and smoothly squeezed between the heating pressure rollers 3 to be applied to the bottom surface of the breathable medical dressing, thereby achieving the purpose of gluing, and the heating pressure rollers 3 can generate heat to accelerate curing.

[0040] like Figure 5 As shown, the intake valve 704 includes a first retaining ring 7041, a first one-way valve ball 7042 and a first power spring 7043;

[0041] The first retaining ring 7041 is fixedly installed in the inner cavity at one end of the top of the cooling water pipe 703, and the first one-way valve ball 7042 is movably installed inside the cooling water pipe 703 and is located on one side of the first retaining ring 7041. The first one-way valve ball 7042 is elastically connected to the inside of the cooling water pipe 703 through the first power spring 7043.

[0042] The above scheme is adopted: by providing a first one-way valve ball 7042, when water vapor accumulates inside the water pipe connected to the air box 702, it will push the first one-way valve ball 7042 to move to one side and open, allowing the gas to smoothly enter the cooling water pipe 703. The design of the first baffle ring 7041 can prevent the first power spring 7043 from pushing the first one-way valve ball 7042 to move to the other side, so that the first power spring 7043 can only move to one side, allowing the gas to enter the cooling water pipe 703 in one direction.

[0043] like Figure 5As shown, the water inlet valve 705 includes a second retaining ring 7051, a second one-way valve ball 7052 and a second power spring 7053;

[0044] The second retaining ring 7051 is fixedly installed on one side of the bottom of the water storage roller 701 and is close to the other end of the cooling water pipe 703. The second one-way valve ball 7052 is movably installed inside the other end of the cooling water pipe 703 and is located on one side of the second retaining ring 7051. The second one-way valve ball 7052 is elastically connected to the inside of the cooling water pipe 703 through the second power spring 7053.

[0045] The above scheme is adopted: by providing a second one-way valve ball 7052, when the water inside the cooling water pipe 703 is pushed by air pressure, the water inside the cooling water pipe 703 will push the second one-way valve ball 7052 to move to one side and open, so that the water can smoothly enter the water storage roller 701 for replenishment, and the design of the second baffle ring 7051 can prevent the second baffle ring 7051 from moving to the other side and opening, thereby preventing the water inside the water storage roller 701 from flowing into the cooling water pipe 703 and affecting the overall circulation.

[0046] like Figure 5 and Figure 7 As shown, a bottom surface cooling mechanism 8 is provided on the inner side of the glue coating machine body 1 and is located below the water storage roller 701. The bottom surface cooling mechanism 8 includes a fixed box 801, a movable seat 802, a synchronous rotating fan assembly 803, a top support frame 804 and a flip block 805;

[0047] The fixed box 801 is arranged inside the gluing machine body 1 and is located below the water storage roller 701. The movable seat 802 is movably installed inside the fixed box 801. The synchronously rotating fan assembly 803 is arranged inside the movable seat 802 and the top passes through the movable seat 802. The top support frame 804 is arranged on the top of the movable seat 802 and is located outside the synchronously rotating fan assembly 803. The flip block 805 is arranged on both sides of the top of the movable seat 802. One side of the bottom of the fixed box 801 is movably sleeved with a driving assembly 9 located below one side of the synchronously rotating fan assembly 803.

[0048] The above scheme is adopted: by providing a synchronous rotating fan assembly 803, when the synchronous rotating fan assembly 803 is extended upward as a whole, it can be driven by the driving assembly 9 to drive the synchronous rotating fan assembly 803 to move, so that the top of the synchronous rotating fan assembly 803 can rotate and blow air to assist in cooling the bottom of the breathable medical dressing.

[0049] like Figure 7 As shown, there are two flip blocks 805 , and both flip blocks 805 are made of rubber.

[0050] The above scheme is adopted: the rubber has good plasticity, so that when the movable seat 802, the synchronous rotating fan assembly 803 and the top support frame 804 move upward as a whole, the surface of the top support frame 804 squeezes and pushes the flip block 805 to deform and flip open, and the movable seat 802, the synchronous rotating fan assembly 803 and the top support frame 804 are reset as a whole, so that the flip block 805 loses the squeezing force and recovers smoothly.

[0051] like Figure 8 As shown, the driving assembly 9 includes a driving wheel 901, a limiting ring 902 and an inner gear block 903;

[0052] The driving wheel 901 is movably sleeved on the bottom of the fixed box 801 and is slidingly connected to the bottom of one side of the synchronous rotating fan assembly 803. The bottom end of the driving wheel 901 extends to the inside of the cooling water pipe 703. The limiting ring 902 is fixedly sleeved on the middle part of the surface of the driving wheel 901 and is located inside the fixed box 801. The inner gear block 903 is arranged at the top of the inner cavity of the driving wheel 901.

[0053] By adopting the above solution, by providing the limiting ring 902 , when the driving wheel 901 as a whole is driven to rotate by the water continuously flowing inside the cooling water pipe 703 , the whole can smoothly rotate under the limiting effect of the limiting ring 902 .

[0054] like Figure 8 As shown, the inner gear block 903 is engaged with one end surface of the bottom of the synchronous rotating fan assembly 803.

[0055] The above scheme is adopted: by providing an internal tooth block 903, when the movable seat 802 and the synchronously rotating fan assembly 803 are extended upward as a whole, the surface of the bottom end of the synchronously rotating fan assembly 803 will be smoothly engaged with the internal tooth block 903 at the top of the driving wheel 901, and then the driving wheel 901 can smoothly drive the overall operation of the synchronously rotating fan assembly 803 by rotating.

[0056] like Figure 6 As shown, a lifting assembly 10 located below the movable seat 802 is disposed inside the fixed box 801, and the lifting assembly 10 includes an air storage bag 101, a limiting rod 102 and a return spring 103;

[0057] The air storage bag 101 is arranged inside the fixed box 801 and is located below the movable seat 802. The limiting rod 102 is arranged inside the fixed box 801 and is located below both sides of the movable seat 802. The surface of the fixed box 801 is slidably connected to the outer end of the movable seat 802. The two ends of the movable seat 802 are elastically connected to the interior of the fixed box 801 through the return spring 103.

[0058] The above scheme is adopted: by providing a return spring 103, since the return spring 103 is in a stretched state, when the gas inside the air bag 101 loses the expansion effect of heat, the air bag 101 can be restored as a whole. At this time, the pulling force of the air bag 101 will be released, and the movable seat 802 and the synchronous rotating fan assembly 803 can be smoothly pulled downward to reset as a whole.

[0059] The working principle and use process of the present invention:

[0060] First, the breathable medical dressing on the surface can be passed through between the heating pressure roller 3 and the glue coating roller 5 through the unwinding mechanism 4, and the other end can be rolled up on the surface of the winding mechanism 2. Then, the glue coating roller 5 can be rotated to apply the glue inside the glue storage frame 6 to the bottom surface of the breathable medical dressing. The heating pressure roller 3 rotates while the internal operation generates heat, which can heat and cure the glued part to complete the entire glue coating operation.

[0061] Then, when the top surface of the heated and glue-coated medical dressing contacts the bottom of the water storage roller 701, the water storage roller 701 absorbs heat and partially evaporates to form water vapor, which is connected to the air box 702 through a water pipe and pushes the first one-way valve ball 7042 to move to one side and open in one direction, so as to smoothly enter the cooling water pipe 703. The water in the cooling water pipe 703 is squeezed by the air pressure, and part of the water pushes the second one-way valve ball 7052 to open to one side, so that part of the water in the cooling water pipe 703 enters the water storage roller 701 for replenishment, thereby achieving the purpose of circulating water cooling.

[0062] When the water at the bottom of the cooling water pipe 703 becomes hot, it will transfer the heat to the air storage bag 101, causing the air pressure inside the air storage bag 101 to expand due to the heat, and then smoothly push the movable seat 802, the synchronous rotating fan assembly 803 and the top support frame 804 to move upward as a whole, until the top support frame 804 pushes the flip block 805 to flip open, allowing the top of the synchronous rotating fan assembly 803 to extend smoothly.

[0063] Afterwards, when the movable seat 802 and the synchronously rotating fan assembly 803 are extended upward as a whole, the teeth at the bottom of one side of the synchronously rotating fan assembly 803 will be fully engaged and connected with the inner tooth block 903 on the top inner wall of the driving wheel 901, and when the water inside the cooling water pipe 703 continues to flow into the water storage roller 701, it will drive the driving wheel 901 as a whole to rotate, and then the synchronously rotating fan assembly 803 can be driven as a whole through the water pipe connecting the air box 702, and finally the top of the synchronously rotating fan assembly 803 can rotate to blow air to the bottom surface of the medical dressing to assist in cooling down, and can also synchronously assist in cooling down the water inside the water storage roller 701.
