Description

Technical Field

[0001] This utility model relates to the field of hot pressing equipment, and in particular to a hot pressing device for a medical absorbent pad. Background Technology

[0002] Medical absorbent pads are often made of loose materials, which can easily shed debris during use, contaminating the operating room environment. Therefore, a semi-permeable polymer film needs to be wrapped around the absorbent material. First, a layer of semi-permeable polymer film is laminated (heat-bonded) onto the absorbent material. After cutting to the appropriate size, another layer of semi-permeable polymer film is wrapped around the other side. The two sides need to be folded over and wrapped. Heating causes the film to laminate with the absorbent material and the film on the other side, thus encasing the absorbent material in the semi-permeable polymer film and preventing debris from falling out. Figure 1 As shown:

[0003] Traditionally, when processing the aforementioned medical absorbent pads, the cut absorbent pads are manually bonded to a semi-permeable polymer film, and then heated and laminated using an electric iron. However, this processing method is relatively inefficient. Utility Model Content

[0019] The following is in conjunction with the appendix Figure 2-4 This application will be described in further detail.

[0020] This application discloses a medical absorbent pad hot pressing device, including a frame 1. The frame 1 is provided with a hot pressing mechanism 2 and a flanging mechanism 3 for flanging the membrane 103. The flanging mechanism 3 includes a flanging pull tube 31 that can flanging the two sides of the membrane 103. The flanging pull tube 31 is flat and includes an inlet 32 ​​and an outlet 33 that are connected to each other. The width of the flanging pull tube 31 gradually decreases from the inlet 32 ​​to the outlet 33. The outlet 33 of the flanging pull tube 31 is provided with an inner tongue 34. A first gap 35 is left between the inner tongue 34 and the inner bottom wall of the outlet 33. A second gap 36 is left between the inner tongue 34 and the left, right and upper inner walls of the outlet 33 for the membrane to pass through. Three through grooves 105 that are connected to the inside of the flanging pull tube 31 are provided on the upper surface of the flanging pull tube 31. During operation, a medical absorbent pad material 10 and two membranes are inserted into the first gap 35. The absorbent pad material is located between the two membranes, and the width of the membrane away from the inner tongue 34 is greater than the width of the other membrane. The shorter membrane is membrane one 101, and the longer membrane is membrane two 102. The flange 103 of membrane two 102 is located in the second gap 36. The width of membrane one 101 is the same as that of the medical absorbent pad material 10.

[0021] Two sets of hot pressing mechanisms 2 are provided. Each set of hot pressing mechanisms 2 includes a conveyor belt 21, a rotating roller 22 rotatably mounted on the frame 1, a first drive mechanism 23 for driving the rotating roller 22 to rotate, and a heating mechanism 24. There are four rotating rollers 22. The conveyor belt 21 is mounted on the four rotating rollers 22. The first drive mechanism 23 includes a drive motor. The rotating rollers 22 in the two sets of hot pressing mechanisms 2 are linked by a gear set and driven by the same drive motor. The two conveyor belts 21 are distributed vertically and vertically and a conveying channel 25 is left between them. The conveyor belt 21 is a high-temperature resistant Teflon conveyor belt 21. The heating mechanism 24 includes a heating plate 241. The heating plate 241 is electrically heated. During the operation, the heating plate 241 contacts the inner side of the conveyor belt 21. The first drive mechanism 23 can drive the rotating roller 22 to rotate, and then through the conveyor belt 21, it can drive all the rotating rollers 22 and the conveyor belt 21 to rotate together. The two conveyor belts 21 rotate in opposite directions. The heating mechanism 24 can heat the two conveyor belts 21. After the medical absorbent pad folded by the flange 103 enters between the two conveyor belts 21, it can be hot-pressed. At the same time as hot pressing, the two conveyor belts 21 can also transport it, thereby realizing continuous hot pressing and transport.

[0022] An expanding roller 4 is rotatably mounted on the frame 1, located between the flanging mechanism 3 and the hot pressing mechanism 2. The folded medical absorbent pad 103 passes through the expanding roller 4 during the conveying process, causing the expanding roller 4 to rotate. Thus, the expanding roller 4 can smooth the folded medical absorbent pad 103, making it flatter before hot pressing.

[0023] The frame 1 includes a frame body 11 and two lifting plates 12 that slide vertically and horizontally on the frame body 11. Two sets of hot pressing mechanisms 2 are respectively installed on the corresponding lifting plates 12. The frame body 11 is provided with a second drive mechanism 13 for driving the lifting plates 12 to move up and down. The second drive mechanism 13 is a cylinder, which is connected to an air pump. The cylinder body is fixedly mounted on the frame body 11, and the piston rod end of the cylinder is fixedly connected to the lifting plate 12. Before processing, the two sets of hot pressing mechanisms 2 can be separated by the cylinder, making the conveying channel 25 larger, thus facilitating the worker to pass the medical absorbent pad material 10 and membrane 101 together through the conveying channel 25.

[0024] A pair of guide wheels 9 are provided on the frame 11. The guide wheels 9 are located between the expansion roller 4 and the hot pressing mechanism 2. The medical absorbent pad material 10 and the membrane are located between the two guide wheels 9.

[0025] The inner tongue 34 includes a limiting plate 341 and two connecting plates 342. The two connecting plates 342 are fixedly mounted on the limiting plate 341, and the limiting plate 341 is fixedly mounted inside the discharge port 33 of the flanged pull cylinder 31 via the two connecting plates 342. A first gap 35 is formed between the limiting plate 341 and the inner bottom wall of the discharge port 33, and a second gap 36 is formed between the limiting plate 341, the connecting plates 342, and the inner side wall of the discharge port 33. The second gap 36 consists of two gaps located on the left and right sides of the first gap 35, and the first gap 35 and the second gap 36 are interconnected. The limiting plate 341 and the connecting plates 342 can position the medical absorbent pad and membrane inside the flanged pull cylinder 31, preventing them from deviating. Before the first processing, the operator will insert the membrane 102 from the feed port 32 into the flange pull tube 31 and out from the discharge port 33. At the same time, the operator will manually intervene to bend the left and right sides of the membrane 102 to form flanges 103 and insert them into the corresponding second gaps 36. The inner walls of the left and right sides of the flange pull tube 31 are arc-shaped, and the width of the flange pull tube 31 gradually decreases from the feed port 32 to the discharge port 33. In this way, as the membrane 102 is continuously conveyed forward, the flange pull tube 31 and the inner tongue 34 can continuously process the flanges 103 on the left and right sides of the membrane 102.

[0026] Each set of hot pressing mechanism 2 has four rotating rollers 22, all located inside the conveyor belt 21 and in contact with the inner side of the conveyor belt 21. Each of the two ends of one rotating roller 22 is rotatably equipped with a slider 5. A sliding groove 6 is provided on the frame 11 for the slider 5 to slide in. The slider 5 is slidably connected within the sliding groove 6. An adjusting bolt 7 is provided on the frame 11 for positioning the slider 5. A through hole 8 is provided on the frame 11 for the threaded section of the adjusting bolt 7 to pass through. The central axis of the through hole 8 is the direction of the slider 5's sliding. The threaded section of the adjusting bolt 7 passes through the through hole 8 and is threadedly connected to the slider 5. Rotating the adjusting bolt 7 moves the slider 5, thereby adjusting the tension of the conveyor belt 21.

[0027] The implementation principle of the medical absorbent pad hot-pressing device in this application embodiment is as follows: Before processing, membrane 101 and absorbent pad material can be unrolled together and then hot-pressed together to form a combined roll 104. The combined roll 104 and membrane 2 102 are then unrolled together and passed through the flange pull tube 31. (When passing through the flange pull tube 31, the operator will manually bend both sides of membrane 2 102 to form flanges 103 and insert the flanges 103 on both sides into the corresponding second gaps 36. Subsequently, during the conveying process, membrane 2 102 can be folded by the flange pull tube 31.) The folded medical absorbent pad (edge ​​103) then passes through the expansion roller 4 and guide wheel 9 in sequence, and finally exits from the conveyor channel 25 to enter the next process (or it can be wound onto the winding roller). The two sets of hot pressing mechanisms 2 are gradually brought together by the cylinder, and the folded medical absorbent pad (edge ​​103) is pressed between the two conveyor belts 21. The heating plate 241 is preheated first, and after reaching the preset temperature, the equipment is started. The folded medical absorbent pad (edge ​​103) is hot-pressed and conveyed by the two conveyor belts 21, so as to achieve continuous hot pressing.

[0028] Alternatively, membrane 101, membrane 2 102, and medical absorbent pad material 10 can be unwound separately and then hot-pressed together using the medical absorbent pad hot-pressing device of this application.

[0029] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
