Description

Technical Field

[0001] This utility model belongs to the field of medical polymer fixation splint production, specifically relating to a double-sided pressing device for the production of medical polymer fixation splints. Background Technology

[0002] Medical polymer fixation splints are a new type of orthopedic external fixation material, composed of high-molecular polyurethane resin and fiber base fabric. They weigh only 1 / 5 of traditional plaster casts, reducing the burden on patients. After curing, their strength is 5-20 times that of plaster casts, effectively fixing fracture sites. Furthermore, their breathability is 200 times that of plaster casts, reducing the risk of skin itching and infection. X-ray examinations can be performed without removal, facilitating observation of healing progress. They cure in 3-5 minutes after activation with room temperature water, can bear weight in 20-30 minutes, and are completely combustible, meeting medical environmental protection requirements.

[0003] However, in the production of medical polymer fixation splints, the two ends between the outer non-woven fabric and the inner lining need to be bonded together with double-sided adhesive. The core layer of the splint is then placed between the outer non-woven fabric and the inner lining, and finally pressed together to achieve double-sided bonding of the splint core layer. However, during the pressing process, the thickness of the splint core layer is greater than the thickness of the double-sided adhesive, resulting in a splint that is higher in the middle and lower on both sides. The main purpose of pressing is to press the double-sided adhesive to achieve a tight connection between the outer non-woven fabric and the inner lining, facilitating subsequent sewing of the outer non-woven fabric and the inner lining. However, common pressing devices directly press the entire splint, and the compression of the splint core layer during the pressing process can easily damage the core layer structure. Moreover, the pressing force is not concentrated enough, resulting in poor adhesion between the outer non-woven fabric and the inner lining by the double-sided adhesive. Therefore, there is an urgent need for a double-sided pressing device for the production of medical polymer fixation splints to solve the above problems. Utility Model Content

[0028] The double-sided pressing device for producing medical polymer fixation splints of this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] This embodiment discloses a double-sided pressing device for producing medical polymer fixation splints. By setting the pressing plate 53 in the double-sided pressing assembly 5, the pressing plate 53 can not only move along the drive plate 51 to adjust the pressing position of the pressing plate 53, adapting to the pressing of different positions of the double-sided adhesive 42, thus improving the practicality of the pressing device, but also the long strip plate 531 can concentrate the pressure on the position of the double-sided adhesive 42 for pressing, reducing the pressing area and concentrating the pressing area at the position that needs to be pressed. This not only increases the pressure during pressing and improves the quality after pressing, but also avoids squeezing the splint core layer 44 during the pressing process, thus avoiding damage to the splint core layer 44, thereby improving the safety during the pressing process. (Refer to...) Figures 1-7 It mainly includes a workbench 1, on the upper part of which a medical polymer fixing clamp 4 is provided, and a hydraulic cylinder 2 is installed on the upper part of the workbench 1. The output end of the hydraulic cylinder 2 is equipped with a double-sided pressing assembly 5 that synchronously presses the two ends of the medical polymer fixing clamp 4.

[0031] like Figure 1 and Figure 2 As shown, a control cabinet 3 is installed on one side of the workbench 1. The control cabinet 3 is electrically connected to the hydraulic cylinder 2 and the double-sided pressing assembly 5. The control cabinet 3 controls the starting of the hydraulic cylinder 2 and the pressing position of the double-sided pressing assembly 5.

[0032] like Figure 6 As shown, the medical polymer fixation splint 4 includes an inner lining 43 disposed on the workbench 1. Double-sided adhesive tape 42 is adhered to both sides of the upper part of the inner lining 43. An outer non-woven fabric 41 is disposed on the upper part of the inner lining 43. Both ends of the outer non-woven fabric 41 are in contact with the side of the corresponding double-sided adhesive tape 42 facing away from the inner lining 43. A splint core layer 44 is disposed between the outer non-woven fabric 41 and the inner lining 43. The splint core layer 44 is disposed between the two double-sided adhesive tapes 42. The thickness of the splint core layer 44 is greater than the thickness of the double-sided adhesive tape 42, so that the medical polymer fixation splint 4 is in a state of protrusion in the middle.

[0033] like Figure 1 and Figure 5 As shown, the double-sided pressing assembly 5 includes a drive plate 51 installed at the output end of the hydraulic cylinder 2. Adjustment plates 54 are slidably connected to both sides of the drive plate 51, and the position of the adjustment plates 54 can be adjusted to adapt to pressing at different positions.

[0034] like Figure 5As shown, a pressing plate 53 is provided at the lower part of the adjusting plate 54. Several sliding posts 55 are fixedly connected to the upper part of the pressing plate 53. The upper parts of the sliding posts 55 are connected together by a connecting plate 57. The connecting plate 57 slides inside the adjusting plate 54. Several springs 56 connect the connecting plate 57 and the adjusting plate 54, and each spring 56 is sleeved on a corresponding sliding post 55. Due to the arrangement of the springs 56, when the pressing plate 53 is pressing, it first stretches the springs 56 to achieve pre-compression. Subsequently, the relative movement between the pressing plate 53 and the adjusting plate 54 brings the pressing plate 53 into contact with the adjusting plate 54. Then, the adjusting plate 54 drives the pressing plate 53 to move downwards for final pressing.

[0035] like Figure 5 As shown, the pressing plate 53 includes a strip plate 531 fixedly connected to the sliding column 55. A rubber strip 532 is fixedly connected to the lower part of the strip plate 531. The rubber strip 532 changes the pressing force of the strip plate 531 on the medical polymer fixation splint 4 from abrupt to a maximum value to a slow increase to a maximum value. The slow release of the pressing force is beneficial to improving the pressing effect of the pressing plate 53 on the medical polymer fixation splint 4.

[0036] like Figure 3 and Figure 7 As shown, each of the two strip plates 531 has a slot 533 on its opposite surface. A retaining strip 534 is engaged in the slot 533. An expansion pressing plate 535 is fixedly connected to the opposite surfaces of the two retaining strips 534. The expansion pressing plate 535 expands the pressing area of ​​the pressing plate 53. By setting the spring 56 and the rubber strip 532, the rubber strip 532 softens the pressing force of the strip plate 531 on the medical polymer fixation clamp 4, which helps to improve the pressing quality of the pressing plate 53 on the medical polymer fixation clamp 4. Moreover, the spring 56 can achieve pre-pressing of the pressing plate 53. Subsequently, the adjusting plate 54 drives the pressing plate 53 to squeeze the medical polymer fixation clamp 4 to complete the pressing work. The pre-pressing of the pressing plate 53 facilitates the subsequent pressing of the pressing plate 53 by the adjusting plate 54, thus improving the overall pressing quality.

[0037] like Figure 3 and Figure 5As shown, a sliding groove 58 is provided on the back of the drive plate 51. Connecting members 59 are fixedly connected to each of the adjusting plates 54. The connecting members 59 slide along the inside of the sliding groove 58. A bidirectional lead screw 52 is rotatably connected to the rear support of the drive plate 51. The connecting members 59 are symmetrically arranged on the two types of threads of the sliding groove 58. By symmetrically arranging the connecting members 59 on the two types of threads of the bidirectional lead screw 52, ​​and by threading the connecting members 59 to the bidirectional lead screw 52, ​​the rotation of the bidirectional lead screw 52 drives the two connecting members 59 to move synchronously. This ensures that the center line connecting the two adjusting plates 54 is aligned, thus facilitating the determination of the pressing position that the pressing device can press.

[0038] like Figure 3 As shown, a motor 8 is mounted on one side of the drive plate 51. A drive gear 7 is fixedly sleeved on the output shaft of the motor 8, and a driven gear 6 meshes with the drive gear 7. The driven gear 6 is fixedly sleeved on one end of the bidirectional lead screw 52. By activating the motor 8, the rotation of the bidirectional lead screw 52 is controlled, thereby adjusting the pressing position of the pressing plate 53. The motor 8 is electrically connected to the control cabinet 3.

[0039] The working principle of the double-sided pressing device for producing medical polymer fixation splints of this utility model:

[0040] When the medical polymer fixation splint 4 is pressed together;

[0041] First, the control cabinet 3 activates the hydraulic cylinder 2, causing the drive plate 51 to move downwards. The downward movement of the drive plate 51 causes the adjusting plate 54 to move downwards. The downward movement of the adjusting plate 54 causes the connecting plate 57 to move downwards. The downward movement of the connecting plate 57 causes the strip plate 531 to move downwards. The downward movement of the strip plate 531 causes the rubber strip 532 to move downwards, pressing the medical polymer fixation clamp 4. At the same time, the movement of the strip plate 531 causes the slot 533 to move. The movement of the slot 533 causes the locking strip 534 to move. The movement of the locking strip 534 causes the expansion pressing plate 535 to move, pressing the medical polymer fixation clamp 4.

[0042] At the same time, the rubber strip 532 squeezes the medical polymer fixation clamp 4, causing the strip plate 531 and the adjustment plate 54 to move relative to each other. The relative movement of the strip plate 531 causes the sliding column 55 to move. The movement of the sliding column 55 causes the connecting plate 57 to move. The movement of the connecting plate 57 causes the spring 56 to be stretched.

[0043] When it is necessary to adjust the pressing position of the pressing plate 53;

[0044] First, the motor 8 is started by the control cabinet 3. The start of the motor 8 drives the drive gear 7 to rotate, the rotation of the drive gear 7 drives the driven gear 6 to rotate, the rotation of the driven gear 6 drives the bidirectional lead screw 52 to rotate, the rotation of the bidirectional lead screw 52 drives the connecting member 59 to move, the movement of the connecting member 59 drives the adjusting plate 54 to move, the movement of the adjusting plate 54 drives the sliding column 55 to move, and the movement of the sliding column 55 drives the pressing plate 53 to move.
