[0002] A mattress is one of the most important parts of bedding and directly affects the comfort of sleep. It has various types, such as spring mattresses, latex mattresses, memory foam mattresses, etc. Spring mattresses have good support and breathability; latex mattresses are natural and environmentally friendly, with good elasticity and conformity; memory foam mattresses can adjust according to the pressure and temperature of the human body to relieve body pressure.

[0003] The patent application with the application number CN202123063896.2 discloses a horizontal hydraulic flattening device for mattress processing, including an operating table.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0030] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation of the present invention.

[0031] In the present invention, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Example 1: Refer to Figures 1-3, the present invention provides a technical solution: a hydraulic cylinder for a bedding machine, including an auxiliary mechanism 1. The auxiliary mechanism 1 includes a support frame 101. A support foot 102 is fixedly connected to the bottom of the support frame 101. A first connecting frame 106 is fixedly connected to the outer wall of the support frame 101. A fixed rod 103 is fixedly connected to the outer wall of the support frame 101. An adjusting mechanism 2 is arranged inside the first connecting frame 106. A first hydraulic rod 104 is fixedly connected to the inner wall of the support frame 101. The output end of the first hydraulic rod 104 is fixedly connected to a support plate 105. After the hydraulic operation of the mattress is completed, the support plate 105 is pushed upward by the first hydraulic rod 104. When the bottom of the support plate 105 is at the same height as the auxiliary roller 306, by pushing one side of the mattress, the unloading operation of the mattress can be carried out. It also includes:

[0033] A positioning mechanism 3, including a second fixing block 301 fixedly connected to the support frame 101. A second motor 302 is fixedly connected to the inner wall of the second fixing block 301. The second motor 302 is set as a synchronous double-shaft motor. The two second rotating shafts 304 drive the push plates 305 to move relatively. A third fixing block 303 is arranged at the output end of the second motor 302. The outer wall of the third fixing block 303 is fixedly connected to the support frame 101. The output end of the second motor 302 passes through the second fixing block 301 and is fixedly connected to a second rotating shaft 304. A push plate 305 is arranged on the inner wall of the support frame 101. After the two push plates 305 move relatively by the second motor 302, the mattress is moved to the central area of the support frame 101, so as to facilitate the adjusting mechanism 2 to position the mattress and improve the accuracy of the extrusion surface of the mattress by the adjusting mechanism 2.

[0034] One end of the first connecting frame 106 away from the support frame 101 is fixedly connected to a second hydraulic rod 107. The number of the second hydraulic rods 107 is two. The two second hydraulic rods 107 are symmetrically arranged with the first connecting frame 106 as the center. A fixing ring 113 is fixedly connected to the top outer wall of the second hydraulic rod 107. A liquid supplement pipe 114 is fixedly connected to the inner wall of the fixing ring 113.

[0035] The output end of the second hydraulic rod 107 is fixedly connected to a first fixing block 108. The bottom outer wall of the second hydraulic rod 107 is slidably connected to the second connecting frame 203. One end of the first fixing block 108 away from the second hydraulic rod 107 is fixedly connected to a first connecting shaft 109. One end of the first connecting shaft 109 away from the first fixing block 108 is fixedly connected to a first connecting block 110. A first motor 111 is fixedly connected to the top of the first connecting block 110. The output end of the first motor 111 passes through the first connecting block 110 and is fixedly connected to a first rotating shaft 112. The number of the first connecting shafts 109 is two. The two first connecting shafts 109 are symmetrically arranged with the central axis of the first connecting block 110 as the center.

[0036] The working principle of this embodiment is as follows: When hydraulic processing of the mattress is required, after the mattress is placed on the support plate 105, the first hydraulic rod 104 drives the mattress to move towards the support frame 101. When the mattress contacts the support frame 101, the second motor 302 positions the mattress through the push plate 305. The second hydraulic rod 107 pushes the first fixing block 108, and the first fixing block 108 pushes the adjusting mechanism 2 towards the mattress. The pressing plate 201 at the bottom of the adjusting mechanism 2 squeezes the mattress. The first motor 111 enables the adjusting mechanism 2 to slide up and down within a certain height through the first rotating shaft 112, achieving the function of fine-tuning the height of the pressing plate 201, thereby compensating for the possible insufficient pressure when the second hydraulic rod 107 leaks, and thus ensuring the qualified rate of the production of bedding.

[0037] Embodiment 2: Please refer to Figure 4 , on the basis of Embodiment 1, the present invention provides a technical solution: The adjusting mechanism 2 includes a first sliding block 202. The top of the first sliding block 202 is fixedly connected with a second connecting frame 203. The bottom of the first sliding block 202 is fixedly connected with a pressing plate 201 through bolts. After the pressing plate 201 contacts the mattress, the mattress exerts pressure on the support plate 105. The outer wall of the pressing plate 201 is slidably connected with the support frame 101. The first motor 111 enables the adjusting mechanism 2 to slide up and down within a certain height through the first rotating shaft 112, achieving the function of fine-tuning the height of the pressing plate 201, thereby compensating for the possible insufficient pressure and improving the qualified rate of the production of bedding.

[0038] A limiting rod 205 is fixedly connected to the outer wall of the second connecting frame 203. The inner wall of the limiting rod 205 is slidably connected with the first connecting shaft 109. A groove 204 is opened at the top of the second connecting frame 203. During the processing of bedding, the possible leaked hydraulic oil is collected through the groove 204, thereby preventing the hydraulic oil from contaminating the bedding. The second hydraulic rod 107 is replenished through the liquid replenishing pipe 114, thereby improving the accuracy of the movement of the second hydraulic rod 107, which is beneficial to improving the qualified rate of the production of bedding. The inner wall of the top of the second connecting frame 203 is slidably connected with the first rotating shaft 112. The first motor 111 can fine-tune the sliding height of the first sliding block 202 through the first rotating shaft 112.

[0039] The working principle of this embodiment is as follows: When the second hydraulic rod 107 pushes the first fixed block 108 downward, the second connecting frame 203 is fixed through the first rotating shaft 112. Thus, the first sliding block 202 slides downward following the second hydraulic rod 107. When the second hydraulic rod 107 squeezes the mattress, if the second hydraulic rod 107 leaks fluid, resulting in insufficient thrust of the second hydraulic rod 107, the first motor 111 drives the first sliding block 202 to slide within a certain height through the first rotating shaft 112 and the second connecting frame 203, thereby compensating for the problem of insufficient second hydraulic thrust. When the second connecting frame 203 moves downward with the first rotating shaft 112, the inner walls on both sides of the second connecting frame 203 are slidably connected to the second hydraulic rod 107.

[0040] Embodiment 3: Please refer to Figures 5-7 , based on Embodiment 1 and Embodiment 2, the present invention provides a technical solution: An auxiliary roller 306 is rotatably connected to the top of the push plate 305 through a rotating shaft. The auxiliary roller 306 is used for the loading and unloading operations of the mattress. A second connecting shaft 307 is fixedly connected to one side of the push plate 305 close to the auxiliary roller 306. The outer surface of the second connecting shaft 307 is slidably connected to the fixed rod 103. One end of the second connecting shaft 307 away from the push plate 305 is fixedly connected to a second connecting block 308. The second motor 302 controls the distance between the two push plates 305 through the second rotating shaft 304, thereby ensuring that the mattress can be located in the central area of the support frame 101.

[0041] One end of the second connecting block 308 away from the second connecting shaft 307 is fixedly connected to a third connecting shaft 309. One end of the third connecting shaft 309 away from the second connecting block 308 penetrates through the third fixed block 303 and is fixedly connected to a second sliding block 310. The inner wall of the second sliding block 310 is rotatably connected to the second rotating shaft 304.

[0042] A force-receiving block 311 is arranged at one end of the second connecting block 308 close to the second sliding block 310. The outer wall of the force-receiving block 311 is fixedly connected to springs 312. The number of the springs 312 is two. The two springs 312 are symmetrically arranged with the central axis of the force-receiving block 311 as the center. One end of the spring 312 away from the force-receiving block 311 is fixedly connected to the second connecting block 308. The inner wall of the force-receiving block 311 is slidably connected to the second connecting shaft 307 and the third connecting shaft 309.

[0043] The working principle of this embodiment is as follows: When the mattress comes into contact with the support frame 101, the second motor 302 pulls the second sliding blocks 310 on both sides through the second rotating shaft 304, and pulls the push plates 305 on both sides through the second sliding blocks 310 to move relatively. When the push plates 305 are moving, when the force-bearing block 311 comes into contact with the fixed rod 103, the force-bearing block 311 squeezes the spring 312, so as to avoid the direct contact between the second connecting blocks 308 and the fixed rod 103, which may cause the deformation of the fixed rod 103 and lead to the abnormal operation of the push plates 305. After the hydraulic operation of the mattress is completed, when the first hydraulic rod 104 pushes the support plate 105 upward, the staff pushes the mattress from one side, and the mattress completes the unloading operation under the rolling of the auxiliary rollers 306.
