[0001] The utility model relates to the technical field of mattress manufacturing, and more specifically, to a mattress turning device. Background Art

[0002] A mattress is an item placed between a human body and a bed to ensure that consumers can obtain healthy and comfortable sleep. There is a wide variety of mattress materials, and mattresses made of different materials can bring different sleeping effects. A mattress mainly consists of four parts: a fabric layer, a filling layer, a support layer, and a bed edge. Each part undertakes different functions and jointly provides a comfortable sleeping experience for users. According to different materials and processes, mattresses can be divided into various types, such as coir mattresses, spring mattresses, latex mattresses, sponge mattresses, 3D material mattresses, and memory foam mattresses, etc. Each type of mattress has its unique characteristics and target users.

[0003] During the mattress production process, mattress turning is a necessary process for subsequent processing such as mattress edging and sewing. The traditional manual turning method is not only inefficient but also labor-intensive, and it is easy to damage the mattress. Although some existing automatic turning devices have solved the above problems to a certain extent, they often have complex structures, large floor areas, and poor adaptability to mattress specifications. Summary of the Utility Model

[0004] Aiming at the existing deficiencies, the utility model provides a mattress turning device, which solves the problems raised in the above background art. By optimizing the design of the turning mechanism, the utility model realizes the rapid and stable turning of the mattress, and at the same time adapts to the turning requirements of mattresses of different specifications and sizes.

[0005] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] A mattress turning device includes a frame. Inside the frame, multiple groups of conveying rollers driven by motors are assembled.

The fixed plate is fixedly arranged at the edge of the upper surface of the connecting plate, and an adjusting screw is threaded through the inside of the fixed plate. A handle is provided at the outer end of the adjusting screw, and the inner end of the adjusting screw is rotatably connected to the conveying frame. A driving shaft is vertically provided on the left side of the conveying frame, and a driven shaft is vertically provided on the right side of the driving shaft. Multiple sets of pulleys are provided on the driven shaft and the driving shaft, and the driven shaft is connected to the pulleys on the driving shaft through a conveyor belt transmission, and the upper end of the driving shaft is fixedly connected to the fifth motor.

[0009] Furthermore, two groups of limiting guide rods are fixedly provided on the back side of the conveying frame, and the limiting guide rods penetrate the fixing plate and are slidably connected thereto.

[0010] Furthermore, guide rods are vertically fixed on both left and right sides of the frame, and support plates are fixed on both left and right sides of the connecting slide, and the support plates are sleeved on the guide rods and slidably connected thereto.

[0011] Furthermore, the transverse limiting mechanism includes a transverse baffle, a positioning groove, a third motor, a threaded sleeve, a double-threaded screw, a connecting rod, a fixing frame, a first sliding block and a first sliding groove. The fixing frame is fixed at the edge of the bottom surface of the flip plate. A rotatable double-threaded screw is provided on the inner side of the fixing frame, and the spiral directions of the two sides of the double-threaded screw on the upper side are opposite. The left end of the double-threaded screw is fixedly connected to the output end of the third motor. A positioning groove is provided inside the flip plate, and a slidable transverse baffle is provided inside the positioning groove. Threaded sleeves are provided on the left and right sides of the double-threaded screw through threaded sleeves.

[0014] Furthermore, a plurality of groups of notches are evenly arranged inside the turning plate.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. By simplifying the turning structure, the overall structure of the utility model is more simplified, which not only reduces the manufacturing cost, but also improves the reliability and stability of the device. Moreover, the device has a compact structure, small floor area, is convenient for installation and use, and can be applicable to mattresses of different specifications, with strong applicability.

[0017] 2. A connecting plate is fixedly arranged at the right end of the turning plate of the utility model, and the right end of the connecting plate is inclined downward to be connected to the conveying roller, and the right end of the connecting plate is arranged in a blade-shaped structure. The main function of the connecting plate is to realize a smooth transition between the turning plate and the conveying roller. When the mattress is conveyed from the conveying roller to the turning plate, the connecting plate can ensure that the mattress will not be blocked or slide down due to the height difference or uneven transition surface. At the same time, the blade-shaped structure at the right end of the connecting plate enables the mattress to naturally slide onto the turning plate along the inclined surface, reducing the resistance and friction during the conveying process.

[0018] 3. The position of the conveying mechanism can be adjusted by the adjusting screw arranged in the utility model, so that the two groups of conveying mechanisms can be adapted to mattresses of different specifications. When the mattress slides from the conveying roller to the connecting plate, the conveying mechanism starts to work. The fifth motor drives the driving shaft to rotate, the belt pulley on the driving shaft rotates accordingly, and drives the belt pulley on the driven shaft to rotate synchronously through the conveyor belt. The mattress is conveyed by the rotation of the conveyor belt, and the mattress is conveyed from the connecting plate to the turning plate.

[0019] 4. The horizontal limiting mechanism provided by the present utility model can ensure that the mattress does not slide horizontally during the flipping process, and can limit the mattress on the flipping plate, thus ensuring the safety and accuracy of the operation. When the third motor is started, it drives the double-threaded screw to rotate. Since the thread spiral directions on the left and right sides of the double-threaded screw are opposite, the two thread sleeves will move relatively simultaneously but in opposite directions. The movement of the thread sleeves drives the connecting rod to rotate, and is transmitted to the horizontal baffle through the connecting rod, causing the horizontal baffle to slide upward in the positioning groove and extend out of the positioning groove, forming a limiting structure at both ends of the flipping plate to ensure that the mattress does not slide horizontally during the flipping process.

[0020] 5. The longitudinal limiting mechanism of the present utility model can clamp and limit the mattress in the longitudinal direction from front to back, ensuring that the mattress does not slide longitudinally during the flipping process and guaranteeing the stability during the flipping process of the mattress. When the fourth motor is started, it drives the top plate to rotate. The rotation of the top plate drives the ejector rod to rotate and move inward. Through the ejector rod, the cross plate (and the second slider and longitudinal baffle connected thereto) slides in the second chute, and further makes the longitudinal baffle move closer inward to realize the clamping and limiting of the mattress. By controlling the forward and reverse rotation of the fourth motor, the longitudinal movement of the longitudinal baffle can be realized, thereby adjusting its position. During the flipping process of the mattress, the longitudinal baffle will firmly block the longitudinal movement of the mattress to prevent it from sliding out of the flipping plate. The operator can adjust the position of the longitudinal baffle according to the length of the mattress and the flipping requirements to ensure the stability and safety during the flipping process of the mattress.

Detailed implementation mode

[0030] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment:

[0032] As Figures 1 to 8 shown, a mattress turning device includes a frame 1. Inside the frame 1, multiple groups of conveying rollers 3 driven by motors are assembled. Above the conveying rollers 3, a U-shaped turning plate 4 is arranged in parallel. On both the front and rear sides of the turning plate 4, L-shaped support plates 17 are provided. Inside the support plates 17, a second motor 16 is assembled. The output end of the second motor 16 is connected to the turning plate 4 through a short shaft. The outer side of the support plate 17 is fixedly connected with a connecting sliding frame 14. Outside the frame 1, a bottom plate 11 is welded. On the bottom plate 11, a frame 5 is fixedly provided. Inside the frame 5, a rotatable threaded screw rod 15 is arranged vertically. At the bottom of the bottom plate 11, a first motor 10 is assembled, and the output end of the first motor 10 is fixedly connected to the lower end of the threaded screw rod 15. The connecting sliding frame 14 is rotationally connected to the threaded screw rod 15 through a thread. At the bottom of the turning plate 4, a longitudinal limiting mechanism 8 is provided. On both the left and right sides of the bottom of the turning plate 4, a lateral limiting mechanism 7 is provided. This design solves the problems that the existing turning devices are often complex in structure, large in floor area, and not strong in adaptability to the mattress specifications.

[0033] In this embodiment, a connection plate 6 is fixedly provided at the right end of the turning plate 4, and the right end of the connection plate 6 is connected to the conveying roller 3 at an angle downward, and the right end of the connection plate 6 is configured as a blade-like structure. The main function of the connection plate 6 is to achieve a smooth transition between the turning plate 4 and the conveying roller 3. When the mattress is conveyed from the conveying roller 3 to the turning plate 4, the connection plate 6 can ensure that the mattress will not be blocked or slide due to the height difference or the uneven transition surface. At the same time, the blade-like structure at the right end of the connection plate 6 allows the mattress to slide naturally along the inclined surface to the turning plate 4, thereby reducing resistance and friction during the conveying process.

[0034] In this embodiment, a conveying mechanism 9 is provided on both the front and rear sides of the upper surface of the connecting plate 6. The conveying mechanism 9 includes a fifth motor 91, a conveying frame 92, a fixed plate 97 and an adjusting screw 99. The fixed plate 97 is fixed at the edge of the upper surface of the connecting plate 6. The adjusting screw 99 is threaded through the fixed plate 97. The outer end of the adjusting screw 99 is equipped with a handle 910. The inner end of the adjusting screw 99 is rotatably connected to the conveying frame 92. A driving shaft 94 is vertically installed on the left side of the conveying frame 92. A driven shaft 95 is vertically installed on the right side of the driving shaft 94. Multiple groups of pulleys 96 are installed on the driven shaft 95 and the driving shaft 94. The driven shaft 95 and the pulleys 96 on the driving shaft 94 are connected by a conveyor belt 93. The upper end of the driving shaft 94 is fixedly connected to the fifth motor 91. When the mattress slides from the conveying roller 3 to the connecting plate 6, the conveying mechanism 9 starts to work. The fifth motor 91 drives the driving shaft 94 to rotate, and the pulley 96 on the driving shaft 94 rotates accordingly, and drives the pulley 96 on the driven shaft 95 to rotate synchronously through the conveyor belt 93, and the mattress is transported by the rotation of the conveyor belt 93, and the mattress is transported from the connecting plate 6 to the turning plate 4. At the same time, the position of the conveying mechanism 9 can be adjusted by the adjustment screw 99, so that the two sets of conveying mechanisms 9 can adapt to mattresses of different specifications.

[0035] In this embodiment, two sets of limiting guide rods 98 are fixedly arranged on the back side of the conveying frame 92, and the limiting guide rods 98 penetrate the fixing plate 97 and are slidably connected thereto. The limiting guide rods 98 play a limiting and guiding role in the movement of the conveying mechanism 9. With the guidance of the limiting guide rods 98, the conveying frame 92 can be precisely adjusted along a predetermined path, limiting the moving range and direction of the conveying frame 92 during the adjustment process, and preventing it from being offset or tilted due to uneven force or improper operation.

[0036] In this embodiment, guide support rods 12 are vertically and fixedly arranged on both the left and right sides inside the frame 5. Support plates 13 are fixedly arranged on both the left and right sides of the connecting carriage 14. The support plates 13 are sleeved on the guide support rods 12 and are slidably connected thereto. The guide support rods 12 are vertically fixed on both the left and right sides inside the frame 5, providing a clear up-and-down movement path for the connecting carriage 14. The support plates 13 are sleeved on the guide support rods 12, ensuring that the connecting carriage 14 can move along a predetermined trajectory during the lifting and lowering process, avoiding deviation or shaking. The guide support rods 12 not only play a guiding role but also provide a solid support for the connecting carriage 14.

[0037] In this embodiment, the lateral limiting mechanism 7 includes a lateral baffle 71, a positioning groove 72, a third motor 73, a threaded sleeve 74, a double-threaded screw rod 75, a connecting rod 76, a fixing frame 77, a first slider 78 and a first chute 79. The fixing frame 77 is fixedly arranged at the bottom edge of the flipping plate 4. A rotatable double-threaded screw rod 75 is arranged inside the fixing frame 77, and the spiral directions of the two threads on the upper side of the double-threaded screw rod 75 are opposite. The left end of the double-threaded screw rod 75 is fixedly connected to the output end of the third motor 73. A positioning groove 72 is formed inside the flipping plate 4, and a slidable lateral baffle 71 is arranged inside the positioning groove 72. Threaded sleeves 74 are sleeved on both the left and right sides of the double-threaded screw rod 75 through threads. A connecting rod 76 is arranged between the threaded sleeve 74 and the lateral baffle 71, and the connecting rod 76 is respectively hinged to the threaded sleeve 74 and the lateral baffle 71. By arranging the lateral limiting mechanism 7, it can be ensured that the mattress will not have lateral sliding during the flipping process, and the mattress can be restricted on the flipping plate 4, thereby ensuring the safety and accuracy of the operation. When the third motor 73 is started, it drives the double-threaded screw rod 75 to rotate. Since the spiral directions of the two threads on the left and right sides of the double-threaded screw rod 75 are opposite, the two threaded sleeves 74 will move relatively simultaneously but in opposite directions. The movement of the threaded sleeve 74 drives the connecting rod 76 to rotate, and is transmitted to the lateral baffle 71 through the connecting rod 76, causing the lateral baffle 71 to slide upward in the positioning groove 72 and extend out of the positioning groove 72, forming a limiting structure at both ends of the flipping plate 4 to ensure that the mattress will not have lateral sliding during the flipping process.

[0038] In this embodiment, first sliders 78 are fixedly arranged at both the left and right ends of the lateral baffle 71. First chutes 79 adapted to the first sliders 78 are formed inside the fixing frame 77. The outer ends of the first sliders 78 are snapped into the first chutes 79 and are slidably connected thereto. The first chutes 79 and the first sliders 78 play a role in limiting the movement of the lateral baffle 71, preventing the lateral baffle 71 from deviating or tilting during the sliding process, thereby ensuring the stability of the lateral limiting mechanism 7.

[0039] In this embodiment, the longitudinal limiting mechanism 8 includes a longitudinal baffle 81, a second chute 82, a second slider 83, a cross plate 84, a jack rod 85, a motor bracket 86, a top plate 87 and a fourth motor 88. Second chutes 82 are provided near the four corners inside the turning plate 4. Second sliders 83 are arranged inside the second chutes 82. The upper side of the second slider 83 is fixedly connected with a longitudinal baffle 81 of a 7-shaped structure. Two groups of second sliders 83 in the transverse direction are connected by a cross plate 84. A motor bracket 86 is fixedly arranged at the center of the bottom of the turning plate 4. A fourth motor 88 is assembled under the motor bracket 86. The output end of the fourth motor 88 is fixedly connected with a top plate 87. Jack rods 85 are hinged at both ends of the top plate 87. The outer ends of the jack rods 85 are hinged with the cross plate 84. The longitudinal limiting mechanism 8 can clamp and limit the mattress in the longitudinal direction from front to back, ensuring that the mattress does not longitudinally slide during the turning process and guaranteeing the stability during the mattress turning process. When the fourth motor 88 is started, it drives the top plate 87 to rotate. The rotation of the top plate 87 drives the jack rods 85 to rotate and move inwards. Through the jack rods 85, the cross plate 84 and the second sliders 83 and longitudinal baffles 81 connected thereto slide in the second chutes 82, so that the longitudinal baffles 81 move closer to each other inwardly, realizing the clamping and limiting of the mattress. By controlling the forward and reverse rotation of the fourth motor 88, the longitudinal movement of the longitudinal baffle 81 can be realized, thereby adjusting its position. During the mattress turning process, the longitudinal baffle 81 will firmly block the longitudinal movement of the mattress to prevent it from sliding out of the turning plate 4. The operator can adjust the position of the longitudinal baffle 81 according to the length of the mattress and the turning requirements to ensure the stability and safety during the mattress turning process.

[0040] In this embodiment, a plurality of groups of notches 41 are evenly opened inside the turning plate 4. By evenly opening the notches 41 inside the turning plate 4, the weight of the turning plate 4 can be effectively reduced, and at the same time, the material cost can be saved.

[0041] The working principle of this mattress flipping device: Initially, the flipping plate 4 is in a horizontal state, and the conveying rollers 3 keep rotating driven by the motor, ready to receive the mattress. The mattress is placed on the conveying rollers 3, and as the conveying rollers 3 rotate, the mattress is conveyed onto the connecting plate 6. The right end of the connecting plate 6 slopes downward and is set as a blade-like structure to ensure that the mattress can smoothly transition from the conveying rollers 3 to the flipping plate 4, reducing resistance and friction. When the mattress slides onto the connecting plate 6, the conveying mechanism 9 starts to work. The fifth motor 91 drives the rotation of the driving shaft 94, and the belt pulley 96 on the driving shaft 94 rotates accordingly, and drives the belt pulley 96 on the driven shaft 95 to rotate synchronously through the conveyor belt 93. The rotation of the conveyor belt 93 conveys the mattress and transports it from the connecting plate 6 to the flipping plate 4. At the same time, the position of the conveying mechanism 9 can be adjusted by the adjusting screw 99 to adapt to mattresses of different specifications. After the mattress is completely placed on the flipping plate 4, the lateral limiting mechanism 7 and the longitudinal limiting mechanism 8 work simultaneously to ensure that the mattress does not slide or fall. In the lateral limiting mechanism 7, the third motor 73 drives the rotation of the double-threaded screw rod 75. Through the transmission of the threaded sleeve 74 and the connecting rod 76, the lateral baffle 71 extends out of the positioning groove 72 to form a limiting structure. In the longitudinal limiting mechanism 8, the fourth motor 88 drives the rotation of the top plate 87, and through the ejector rod 85, the cross plate 84 and the longitudinal baffle 81 slide in the second chute 82 to achieve clamping and limiting of the mattress. Then, the first motor 10 drives the rotation of the threaded lead screw 15 to control the lifting height of the connecting carriage 14 and the flipping plate 4, so as to raise the flipping plate 4 together with the mattress to an appropriate position. Then the second motor 16 starts and drives the flipping plate 4 to flip through the short shaft. After the flipping is completed, the first motor 10 drives the rotation of the threaded lead screw 15 to control the descent of the flipping plate 4, so that the flipping plate 4 moves downward until it is close to the conveying rollers 3. Then, the longitudinal limiting mechanism 8 and the lateral limiting mechanism 7 are removed from limiting the mattress, so that the mattress inside the flipping plate 4 falls on the conveying rollers 3, and the flipped mattress is conveyed to the next process through the conveying rollers 3.

[0042] In summary, through the coordinated action of each component, this mattress flipping device realizes the smooth conveying, flipping and limiting fixation of the mattress. Its design is simple and efficient, occupies a small area, and has strong adaptability to mattress specifications.

[0043] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation modes of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to enumerate all the implementation modes here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
