DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. 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.

[0024] In order to further understand the content of the invention, this technical solution is further described below in conjunction with specific implementation methods.

[0025] Example 1: Figures 1 to 6As shown, this embodiment provides an online insertion device for a catheter in an elastic mattress, which specifically includes an operating platform 1, a machine head, a mouth template 4, and a molding roller, which are arranged in sequence from top to bottom. The machine head includes a first machine head 2 and a second machine head 3. The first machine head 2 and the second machine head 3 have a flow channel 15 for the flow of molten raw materials inside. The mouth template 4 is attached to the bottom surface of the first machine head 2 and the second machine head 3. There is a certain distance between the molding roller and the mouth template 4. The molding roller includes a first molding roller 5 and a second molding roller 6. The first molding roller 5 and the second molding roller 6 rotate in opposite directions. A through groove for the catheter 8 to pass through and / or move is provided on the operating platform 1. The channel pipe 7 is arranged from top to bottom according to The first machine head 2 and the second machine head 3 are arranged on both sides of the channel tube 7. Specifically, there is a gap between the first machine head 2 and the second machine head 3, and the channel tube 7 can move in this gap. A walking mechanism 14 is arranged on the operating platform 1. The walking mechanism 14 specifically includes a base A, a motor, a gear and a rack. The motor is installed on the base A. The rack is fixed on the operating platform 1 and the rack is arranged in the same direction as the length of the gap between the first machine head 2 and the second machine head 3. The rack constitutes a linear guide rail, the gear is meshed with the rack, and the rack and the gear constitute a transmission chain. The motor drives the gear to rotate and move. The top of the channel tube 7 also penetrates and is fixed on the base A of the walking mechanism 14. The walking mechanism 14 drives the catheter 8 to move in the horizontal direction along the rack. For example, if the motor rotates forward, the walking mechanism 14 moves horizontally to the left; if the motor rotates backward, the walking mechanism 14 moves horizontally to the right, thereby driving the channel tube 7 and the catheter 8 to move back and forth in the horizontal direction. The walking mechanism 14 is provided with a conveying mechanism, which transports the conduit 8 downward. After passing through the channel tube 7, the conduit 8 moves downward in parallel with the filament bundle 9 extruded from the first head 2, the second head 3 and the mouth template 4. After the conduit 8 and the filament bundle 9 pass through the gap between the first forming roller 5 and the second forming roller 6 rotating in opposite directions, the filament bundle 9 forms a disordered tangled filament shape and connection points are formed between the filament bundles 9 and between the filament bundles 9 and the conduit 8 at the places where they contact each other, so that the conduit 8 is placed between the filament bundles 9 to form a mattress with the conduit 8.

[0026] The conveying mechanism includes a first conveying guide roller 10 and a second conveying guide roller 11, which rotate toward each other to clamp and transport the catheter 8 downward. A cylinder 12 is also provided at the axial end of the first conveying guide roller 10, and the cylinder 12 is used to adjust the distance between the first conveying guide roller 10 and the second conveying guide roller 11, that is, the first conveying guide roller 10 can rotate and can also move horizontally under the drive of the cylinder 12; the second conveying guide roller 11 can rotate but cannot move horizontally. The conveying speed of the conveying mechanism is adjustable. The cylinder 12 is a cylinder with adjustable stroke, and the distance between the first conveying guide roller 10 and the second conveying guide roller 11 is adjusted by the cylinder 12. The smaller the distance between the first conveying guide roller 10 and the second conveying guide roller 11, the greater the clamping force, and the larger the distance between the first conveying guide roller 10 and the second conveying guide roller 11, the smaller the clamping force. The catheter 8 is wound in a storage tray 13, and the storage tray 13 is located above the conveying mechanism. The storage tray is provided to facilitate the placement or use of the catheter 8.

[0027] like Figure 1 As shown, the motor rotates forward, and the walking mechanism 14 gradually moves from the leftmost side to the rightmost side in the figure. The forming roller is also provided with a cooling device and a cutting device in sequence. The cooling device is air-cooled or water-cooled. In this embodiment, water-cooled is adopted, that is, the horizontal center of the forming roller is placed on the water surface to cool and shape it. The cutting device is to cut and trim the mattress after cooling and shaping. The cooling device and the cutting device are both existing technologies and will not be described in detail.

[0028] Example 2: Different from Example 1, the walking mechanism 14 includes a rodless cylinder and a base B. The rodless cylinder is fixed on the operating platform 1, and the base B is fixed on the slider of the rodless cylinder. The top of the channel tube 7 passes through and is fixed on the base B of the walking mechanism 14. The movement of the slider drives the base B to move, and then drives the channel tube 7 and the conduit 8 to move in the horizontal direction.

[0029] The base B in the embodiment 2 and the base A in the embodiment 1 are both connected to the conveying mechanism, that is, the first conveying guide roller 10 and the second conveying guide roller 11 in the embodiment 1 are installed on the base A, and the first conveying guide roller 10 and the second conveying guide roller 11 in the embodiment 2 are installed on the base B. There is no difference between the base A and the base B, which is just for the convenience of technical personnel in this field to understand the present technical solution.

[0030] Embodiment 3: Different from Embodiment 1, the wall of the catheter 8 is provided with small holes all around.

[0031] Example 4: Figures 1 to 6As shown, based on the embodiment 1, this embodiment provides an online insertion method of the conduit in the elastic mattress, which specifically includes: the conveying mechanism conveys the conduit 8 downward, and the walking mechanism 14 moves along the rack, and the conduit 8 moves in the vertical direction and the horizontal direction at the same time, so that the movement trajectory of the conduit 8 in space is S-shaped downward, and at the same time, the raw material is heated and plasticized into a molten state by the extruder, and the filament bundle 9 is extruded through the first head 2, the second head 3 and the die plate 4, and the conduit 8 extends from the channel tube 7, and the filament bundle 9 is located at the outer periphery of the conduit 8. After the filament bundle 9 and the conduit 8 fall into the gap between the first forming roller 5 and the second forming roller 6 rotating in opposite directions, the filament bundle 9 forms a disordered mess of filaments, and the filament bundle 9 and the filament bundle 9 and the conduit 8 form connection points at the mutual contact points, so that the conduit 8 is inserted between the filament bundles 9 to form a mattress with the conduit 8. That is to say, the conveying mechanism and the walking mechanism 14 are used to transport the conduit 8 at the set speed and path, so that it enters the space between the first forming roller 5 and the second forming roller 6 rotating in opposite directions along the elastic filament bundle 9 path to form a mattress. The mattress with the conduit 8 is then cooled and shaped; the shaped mattress is then cut to form a product.

[0032] The conduit 8 of the mattress has a water inlet and a water outlet at its head and tail ends respectively. The water inlet is connected to a water pump and a temperature-regulating water tank. A temperature and humidity detector and a temperature and humidity regulator are also provided in the mattress. Hot water or cold water can be introduced into the conduit 8 as needed according to different seasons to heat or cool the mattress.

[0033] Embodiment 5: Different from Embodiment 4, the wall of the conduit 8 has small holes for adjusting humidity. Water mist is introduced into the conduit 8 or moisture around the conduit 8 is discharged out of the mattress through negative pressure, so as to adjust the humidity of the mattress.

[0034] It should be noted that the first conveying guide roller 10 and the second conveying guide roller 11 can also be designed to be able to move horizontally. The walking mechanism 14 controls the catheter 8 to move along the specified path. Specifically, the walking mechanism 14 moves in the horizontal direction and then drives the catheter 8 and the channel tube 7 to move horizontally. While the catheter 8 and the channel tube 7 move horizontally, the catheter 8 is controlled by the conveying mechanism to move downward in the vertical direction, so that the movement trajectory of the catheter 8 in space is S-shaped downward. In addition to the two walking mechanisms 14 in the above embodiment, the walking mechanism 14 can also use a worm gear device to achieve horizontal movement. This method is a prior art and the specific content is not repeated. The catheter 8 is directly inserted during the production process without destroying the flatness and structural integrity of the mattress, ensuring that the product is intact; the dual control of the conveying mechanism and the walking mechanism 14 realizes the flexibility and accuracy of the operation, realizes the precise movement and precise insertion of the catheter 8, greatly improves the production efficiency, and eliminates the complicated process of inserting the catheter 8 twice. In addition, the composite movement of the conveying mechanism and the walking mechanism 14 can stably ensure the layout and shape and size of the catheter 8 in the mattress. By adjusting the speed of the walking platform and the conveying mechanism respectively, different shapes of S-shaped conduits 8 can be realized, the pitch size of the arrangement of adjacent conduits 8 can be changed, and the density of the arrangement of conduits 8 in the mattress can be changed. The mattress can be heated or cooled by passing hot or cold water into the conduit 8 according to actual needs; a conduit 8 with small holes can also be placed, and water mist can be passed into the conduit 8 to humidify or moisture can be discharged from the mattress through negative pressure, thereby increasing the comfort of use and improving product competitiveness.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
