Description

Technical Field

[0001] This utility model relates to the field of medical surgical towel production technology, and in particular to a surgical towel three-folding device. Background Technology

[0002] Surgical drapes are key consumables used in clinical surgery to isolate contamination and protect the sterile environment of the surgical area. Before use, they need to be folded into a fixed square size to fit the standardized sterilization and packaging process, ensuring convenient storage, transportation and retrieval. Currently, surgical drape folding mainly relies on two methods, both of which have significant technical drawbacks: First, there is the issue of manual folding. Operators need to manually complete three folds in two directions, which is not only inefficient, but also prone to size deviations due to fatigue and differences in technique, affecting the subsequent sealing of the packaging. The manual handling process increases the risk of surgical towel contamination, requiring additional manpower for aseptic checks, thus increasing labor and time costs. Secondly, there is the issue of existing mechanized folding equipment. The mainstream equipment on the market is a two-folding machine, which works by folding twice in only one direction. The finished product is rectangular, which cannot meet the square size requirements of three-folding in two directions. This is completely out of step with the size requirements of standardized packaging of surgical drapes, meaning that this type of equipment can only be used for folding non-sterile drapes and cannot be adapted to the core usage scenario of medical surgical drapes. Summary of the Invention The technical problem to be solved by this utility model is that the current folding of medical surgical towels relies on manual labor or existing two-folding equipment, making it difficult to achieve efficient, accurate, and standardized two-way three-folding for sterilization and packaging.

[0003] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a surgical drape three-folding device, comprising a first folding component that folds a vertical surgical drape into a horizontal state, a second folding component that folds one end of the surgical drape along a trisection line, a third folding component that folds the other end of the surgical drape along another trisection line, and a fourth folding component that folds the surgical drape in another direction. The first, second, and fourth folding components are each provided with a conveyor, a pressing component that tightly presses the surgical drape against the surface of the conveyor belt, and a folding mechanism that folds the surgical drape in a straight line. The third folding component is provided with a receiving belt that can move forward and backward and receive vertical surgical drapes.

[0004] Preferably, the folding mechanism includes a movable disk, a connecting rod hinged to the edge of the movable disk, and an insert plate axially slidably arranged on a slide rail; The axis of the movable disk is located on the extension line of the slide rail along its length. A movable block for installing the insert plate is slidably mounted on the slide rail, and the other end of the connecting rod is hinged to the movable block.

[0005] Preferably, the first folding assembly includes a horizontally fixed tray, a first conveyor belt horizontally rotatably arranged above the tray, and a first folding mechanism located below the tray. A clamping seam for accommodating the surgical towel is provided between the bottom of the first conveyor belt and the top surface of the tray. The first folding mechanism is horizontally arranged, and the first folding mechanism is on the same straight line as the middle of the surgical towel moving on the tray.

[0006] Preferably, the second folding assembly includes a second conveyor belt arranged in a horizontal rotation and a second pressure belt arranged in a horizontal rotation above the second conveyor belt. A gap is provided between the second conveyor belt and the second pressure belt for the surgical towel to pass through, and the first folding mechanism is directly opposite the gap between the second conveyor belt and the second pressure belt. A third pressure belt is provided on one side of the tail end of the second conveyor belt. A vertically distributed gap is provided between the second conveyor belt and the third pressure belt. A second folding mechanism is vertically arranged directly above the gap.

[0007] Preferably, the top of the third pressure belt is provided with an inclined surface, and the top end of the third pressure belt is located close to the second conveyor belt. An infrared sensor for detecting the surgical towel is provided on the top of the third pressure belt.

[0008] Preferably, the third folding assembly includes a third conveyor belt rotatably arranged below the third pressure belt, the pressure belt, and a receiving belt. The receiving belt is located directly below the second folding mechanism. The receiving belt rotates in the opposite direction before receiving the surgical towel, and rotates in the forward direction after rotating a distance reaching one-third of the length of the middle of the surgical towel, thus feeding the surgical towel out to the third conveyor belt.

[0009] Preferably, the fourth folding assembly includes a housing, a fourth folding mechanism vertically arranged at the bottom of the housing, and a fourth conveyor belt and a fourth pressure belt arranged on both sides above the fourth folding mechanism. The unloading end of the output belt of the third folding assembly is located inside the housing, and the fourth folding mechanism is located directly below the output belt. A gap for accommodating the surgical drape is provided between the fourth conveyor belt and the fourth pressure belt. The gap includes a vertical section and a horizontal section, with the horizontal section connected to the top of the vertical section. The fourth folding mechanism and the vertical section are on the same vertical plane.

[0010] This utility model provides a three-fold surgical towel device, which has the following beneficial effects.

[0011] The surgical towel is folded using four folding components. The first folding component folds it in half, the second and third folding components fold it into thirds, and the half-folding mechanism folds it in another direction, thus realizing the automated three-folding of the surgical towel. This not only meets the need for automatic folding of surgical towels but also improves the efficiency of folding surgical towels. Attached Figure Description

[0016] like Figure 1-3 As shown, this utility model provides a surgical drape three-folding device, including a first folding assembly arranged sequentially along the surgical drape moving direction to fold a vertical surgical drape into a horizontal state, a second folding assembly to fold one end of the surgical drape along a trisection line, a third folding assembly to fold the other end of the surgical drape along another trisection line, and a fourth folding assembly 12 to fold the surgical drape in another direction. The first folding assembly, the second folding assembly, and the fourth folding assembly 12 are each provided with a conveyor, a pressing member to tightly press the surgical drape against the surface of the conveyor belt, and a folding mechanism to fold the surgical drape in a straight line. The third folding assembly is provided with a receiving belt 9 that can move forward and reverse and receive vertical surgical drapes.

[0017] The surgical towel is hung on the first folding assembly and conveyed axially through the first folding assembly. When the surgical towel is conveyed to the end of the first folding assembly, the middle part of the surgical towel is inserted into the gap between the two sets of belts in the second folding assembly through the folding mechanism inside the first folding assembly, thereby realizing one fold of the surgical towel. The surgical towel is then transported via the second folding assembly. When the surgical towel moves to the unloading end of the second folding assembly, the front end of the surgical towel moves to the third folding assembly. When the end of the surgical towel is detected by the corresponding infrared sensor, the trisection line near the front end of the surgical towel is located directly below the folding mechanism in the second folding assembly. The folding mechanism folds the front end of the surgical towel at the trisection point, causing the surgical towel to move along the gap between the second folding assembly and the third folding assembly. During the movement, the surgical towel falls onto the receiving belt 9 in the third folding assembly. The receiving belt 9 rotates in the reverse direction, causing the surgical towel to move one-third of its length. Then the receiving belt 9 rotates in the forward direction, so that the unfolded one-third of the length of the surgical towel at the rear end covers the middle of the surgical towel, realizing the three-part folding of the surgical towel, and sending the folded surgical towel out to the fourth folding assembly 12. The folded surgical towel is conveyed to the fourth folding component 12 via the third folding component. The fourth folding component 12 folds the surgical towel in another direction and sends it out, thus meeting the folding requirements of the surgical towel packaging.

[0018] like Figure 1 As shown. The folding mechanism includes a movable disk, a connecting rod hinged to the edge of the movable disk, and an insert plate axially slidably arranged on a slide rail; The axis of the movable disk is located on the extension line of the slide rail along its length. A movable block for installing the insert plate is slidably mounted on the slide rail, and the other end of the connecting rod is hinged to the movable block.

[0019] The moving disk is driven by a motor to rotate. During the rotation, the moving disk pulls the connecting rod to rotate, and the connecting rod pulls the slider to move back and forth along the slide rail. This in turn drives the insert plate on the moving block to move back and forth. During the movement, the insert plate folds the surgical towel according to the corresponding gap.

[0020] like Figure 1 and Figure 3 As shown. The first folding assembly includes a horizontally fixed tray 2, a first conveyor belt 4 horizontally rotatably arranged above the tray 2, and a first folding mechanism 1 located below the tray 2. A clamping seam for accommodating the surgical towel is provided between the bottom of the first conveyor belt 4 and the top surface of the tray 2. The first folding mechanism 1 is horizontally arranged, and the first folding mechanism 1 and the middle of the surgical towel moving on the tray 2 are on the same straight line.

[0021] When the first folding assembly performs the first fold of the surgical towel, the surgical towel is suspended on the tray 2. The top of the surgical towel is held by the first conveyor belt 4. During the rotation of the first conveyor belt 4, the surgical towel is driven to slide horizontally along the tray 2 through friction. When the surgical towel moves to the unloading end of the tray 2, the insert plate in the first folding mechanism 1 moves and the insert plate moves the middle of the surgical towel toward the belt gap in the second folding assembly, realizing the first fold of the surgical towel.

[0022] The tray 2 is L-shaped, and a first limiting belt 3 is provided on one side of the tray 2. The first limiting belt 3 is used to cooperate with the vertical section on the side of the tray 2 to maintain the movement gap of the surgical towel, while limiting the position of the surgical towel to ensure that the first folding mechanism 1 folds the surgical towel accurately.

[0023] like Figure 1 and Figure 3 As shown. The second folding assembly includes a second conveyor belt 6 arranged in a horizontal rotation and a second pressure belt 5 arranged in a horizontal rotation above the second conveyor belt 6. A gap is provided between the second conveyor belt 6 and the second pressure belt 5 for the surgical drape to pass through, and the first folding mechanism 1 is directly opposite the gap between the second conveyor belt 6 and the second pressure belt 5. A third pressure belt 7 is provided on one side of the tail end of the second conveyor belt 6. A vertically distributed gap is provided between the second conveyor belt 6 and the third pressure belt 7. A second folding mechanism 8 is vertically arranged directly above the gap.

[0024] After the surgical towel is folded once, it is transported by the second conveyor belt 6 and the second pressure belt 5. When the front end of the surgical towel moves to the third pressure belt 7, the front end of the surgical towel is folded by the second folding mechanism 8 to achieve a three-fold at one end. At this time, the surgical towel enters the gap between the second conveyor belt 6 and the third pressure belt 7.

[0025] like Figure 1 and Figure 3 As shown. The top of the third pressure belt 7 is provided with an inclined surface, and the top of the third pressure belt 7 is located close to the second conveyor belt 6. An infrared sensor for detecting the surgical towel is provided on the top of the third pressure belt 7.

[0026] When the surgical towel is transported by the second conveyor belt 6, the front end of the surgical towel can fall smoothly onto the third pressure belt 7 due to the inclined surface at the top of the third pressure belt 7. The infrared sensor detects this and then controls the second folding mechanism 8 to fold the surgical towel in a timely manner.

[0027] like Figure 1 and Figure 3As shown. The third folding assembly includes a third conveyor belt 10 rotatably arranged below the third pressure belt 7, the pressure belt 7, and a receiving belt 9. The receiving belt 9 is located directly below the second folding mechanism 8. The receiving belt 9 receives the surgical drape and rotates in the reverse direction before rotating to the right after reaching one-third of the length of the middle of the surgical drape, thus sending the surgical drape out to the third conveyor belt 10. When the surgical drape moves within the third folding assembly, it first passes through the gap between the third pressure belt 7 and the second conveyor belt 6. The folded front end of the surgical drape falls onto the receiving belt 9. At this time, the receiving belt 9 reverses direction. After the folded front end of the surgical drape bends and falls onto the receiving belt 9, the receiving belt 9 rotates forward, so that the unfolded rear end of the surgical drape gradually covers the folded part of the surgical drape, thereby realizing the third fold of the surgical drape. Finally, the surgical drape is conveyed to the third conveyor belt 10, and then sent out to the fourth folding assembly 12 via the third conveyor belt 10.

[0028] like Figure 1-3 As shown. The fourth folding assembly 12 includes a housing, a fourth folding mechanism 14 vertically arranged at the bottom of the housing, and a fourth conveyor belt 16 and a fourth pressure belt 17 arranged on both sides above the fourth folding mechanism 14. The unloading end of the output belt of the third folding assembly is located inside the housing, and the fourth folding mechanism 14 is located directly below the output belt. A gap for accommodating the surgical drape is provided between the fourth conveyor belt 16 and the fourth pressure belt 17. The gap includes a vertical section and a horizontal section, with the horizontal section connected to the top of the vertical section. The fourth folding mechanism 14 and the vertical section are on the same vertical plane.

[0029] The unloading end of the third conveyor belt 10 is located inside the housing. The third conveyor belt 10 has multiple sections along the axial direction of the mounting shaft, and there is a gap between adjacent ends. The fourth folding mechanism 14 is located directly below the gap. After the third conveyor belt 10 conveys the surgical towel into the housing, after detecting that the surgical towel has moved into place, the fourth folding mechanism 14 is controlled to lift the surgical towel along the center line, so that the surgical towel enters the gap between the fourth conveyor belt 16 and the fourth pressing belt 17, and folds the surgical towel in the other direction, and outputs the surgical towel horizontally from the top.
