[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-3 This utility model provides a technical solution:
[0024] A device for filling the interior of sofa cushions includes a base plate 1, a filling machine 2 fixedly mounted on the top of the base plate 1, a filling tube 3 connected to one side of the filling machine 2, and a U-shaped support frame 4 fixedly mounted on the top of the base plate 1. The base plate 1 provides a stable foundation for the device, ensuring the overall structure is stable and preventing displacement or vibration during the filling operation. The filling machine 2 achieves automated filling through the filling tube 3, improving efficiency and reducing manual operation. The open design of the U-shaped support frame 4 allows operators to observe and adjust the filling process, improving operational convenience.
[0025] Specifically, a receiving plate 5 is installed on one side of the U-shaped support frame 4, and a support plate 6 is installed on the side of the receiving plate 5 away from the U-shaped support frame 4. The U-shaped support frame 4 is equipped with a clamping component 7 for clamping and fixing the filling head of the sofa cushion. The top of the receiving plate 5 is equipped with an elastic component 8 for elastically supporting sofa cushions of different shapes. The receiving plate 5 is used to support sofa cushions of different shapes, providing initial support and ensuring that the cushion remains stable during filling. The clamping component 7 can clamp and fix the filling head of the sofa cushion on the receiving plate 5. Together with the elastic component 8, it can provide elastic support for the sofa cushion during filling, thereby adapting to the stable filling operation of sofa cushions with different contours.
[0026] Specifically, the clamping assembly 7 includes a first electric push rod 71 fixedly mounted on the top of the U-shaped support frame 4. A fixing plate 72 is fixedly mounted inside the U-shaped support frame 4. A second electric push rod 73 is fixedly mounted on the bottom of the fixing plate 72. Push plates 74 are fixedly mounted on the telescopic ends of the first electric push rod 71 and the second electric push rod 73, respectively. Both sets of push plates 74 are slidably disposed inside the U-shaped support frame 4. Two sets of push rods 75 are respectively mounted on the opposite side of the two sets of push plates 74. A clamping plate 76 is mounted on the end of the multiple sets of push rods 75 away from the push plates 74. Through the arrangement of the clamping assembly 7, the first electric push rod 71 can be used to clamp the top of the U-shaped support frame 4. The movable push rod 71 and the second electric push rod 73 can be selected from the DMD series electric push rods of Demark. Electric push rods are existing technology, and will not be described in detail. The push rod force can be adjusted in real time to avoid overpressure damage to the cushion fabric. The controller controls the first electric push rod 71 and the second electric push rod 73 to drive the push plate 74 synchronously, which drives the clamping plate 76 to clamp the filling head of the sofa cushion in both directions, ensuring that the filling tube 3 is firmly connected and preventing it from falling off or shifting during the filling process. Therefore, the push plates 74 moving in opposite directions achieve symmetrical clamping, ensuring that the filling tube 3 is subjected to balanced force and avoiding the problem of connection shift caused by pressure on one side.
[0027] Specifically, each of the two sets of clamping plates 76 has an arc-shaped groove 9 on one side facing each other, which engages with the outside of the filling tube 3. Both sets of clamping plates 76 are slidably disposed inside the U-shaped support frame 4. By matching the outer wall of the filling tube 3 with the arc-shaped groove 9, the sealing performance is improved and the leakage of the filling material is prevented. The clamping plates 76 are slidably disposed inside the U-shaped support frame 4, which guides and constrains the movement of the two sets of clamping plates 76 and also makes the clamping force of the clamping plates 76 evenly distributed.
[0028] Specifically, sliders 10 are installed on both sides of the two sets of push plates 74. Two sets of slide grooves 11 are opened on both sides of the U-shaped support frame 4 for the sliders 10 to slide. Multiple sets of sliders 10 are slidably arranged in multiple sets of slide grooves 11. By combining the sliders 10 and slide grooves 11 arranged symmetrically on both sides, a stable linear motion is formed, ensuring that the push plate 74 always maintains a precise straight-line motion trajectory and avoiding deviation during clamping.
[0029] Specifically, the elastic component 8 includes a movable plate 81 mounted on top of the receiving plate 5. Two sets of first limiting pins 82 are symmetrically installed on both sides of the movable plate 81. Elastic bands 83 are respectively arranged on the outer sides of the multiple sets of first limiting pins 82. Second limiting pins 84 are symmetrically installed on both sides of the U-shaped support frame 4. The ends of the multiple sets of elastic bands 83 away from the first limiting pins 82 are respectively arranged on the outer sides of the multiple sets of second limiting pins 84. Through the setting of the elastic component 8, the elastic bands 83 connect the movable plate 81 and the limiting pin structure of the support frame to form a flexible suspension system. The support force can be automatically adjusted according to the different shapes and thicknesses of sofa cushions to achieve an adaptive elastic support effect. The symmetrical arrangement of multiple sets of elastic bands 83 makes the force on each part of the movable plate 81 balanced, avoids local stress concentration, and ensures that the cushions receive uniform support during the filling process. The combination of limiting pins and elastic bands 83 achieves the elastic support function without the need for a complex transmission mechanism. The overall structure is simple and compact, and easy to maintain.
[0030] Specifically, multiple sets of slide rods 12 are installed on the side of the movable plate 81 away from the U-shaped support frame 4. The multiple sets of slide rods 12 are slidably arranged inside the support plate 6. Through the arrangement of the slide rods 12, the multiple sets of slide rods 12 are arranged in parallel to form a stable guiding system, ensuring that the movable plate 81 maintains horizontal movement during the elastic support process and preventing tilting or jamming.
[0031] Specifically, multiple sets of slide rods 12 are arranged in a rectangular array. The ends of the slide rods 12 away from the moving plate 81 all pass through the support plate 6 and are fitted with limit plates 13. Through the setting of the limit plates 13 of the slide rods 12, the rectangular array arrangement forms a uniform force network, so that the supporting force of the moving plate 81 is effectively transmitted to the support plate 6 through the multiple slide rods 12, avoiding stress concentration. The limit plates 13 form a mechanical stop, ensuring that the stroke of the moving plate 81 is always within a safe range and preventing overload damage.
[0032] Specifically, the bottom of the support plate 6 is fixedly connected to the top of the base plate 1. The support plate 6 is T-shaped. The T-shaped support plate 6 enhances the overall rigidity and provides a sliding track for the slide bar 12, making the elastic support more stable.
[0033] Working Principle: When using this invention, the sofa cushion is placed on the receiving plate 5, and its position is adjusted so that the filling opening is aligned with the filling tube 3. Then, the clamping assembly 7 is activated. The first electric push rod 71 and the second electric push rod 73 in the clamping assembly 7 drive the upper and lower push plates 74 respectively. The push rod 75 links the clamping plate 76 to achieve bidirectional clamping force. The arc groove 9 fits tightly against the outer wall of the filling tube 3 to prevent the filling material from leaking or scattering. At the same time, it presses the edge of the cushion opening, thereby clamping and fixing the sofa cushion. Then, the filling machine 2 injects material into the sofa cushion through the filling tube 3. At this time, the elastic component 8 compensates for the deformation caused by the filling pressure in real time. The elastic band 83 and the slide rod 12 in the elastic component 8 adaptively contract or extend according to the shape of the cushion, thereby providing multi-point flexible support and preventing the cushion from shifting during filling. After filling is completed, the clamping assembly 7 is released, the finished cushion is taken out, the slide rod 12 rebounds under the action of the elastic band 83, and the moving plate 81 is reset, thus completing the filling operation of the sofa cushion.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
