[0002] During the processing and production of mattresses, raw materials such as sponges or latex need to be cut and formed first for subsequent assembly work.

[0003] During the cutting process, a positioning or guiding device is required to limit the position of the material. For example, a cutting device for mattress processing disclosed in Chinese Patent CN214819008U guides and limits the material through a pair of limit plates with adjustable spacing, and then presses the upper surface of the material through a pressing plate and a second rotating roller. Although it prevents the material from shifting and the cut edge from warping, since the positions of the pressing plate and the second rotating roller are fixed, the movement of the cutting knife is limited, and the shape of the cut cannot be adjusted.

Detailed implementation manners

[0027] In order to make the technical problems, technical solutions and beneficial effects solved by the invention more clear and understandable, the following further describes the invention in combination with the drawings and embodiments.

[0028] As Figures 1 to 7 shown, the present invention provides a cutting and forming device for mattress processing and production, including a frame 1 and a plurality of conveying rollers 2 installed on the frame 1. First linear modules 3 are provided on both sides of the frame 1. A movable frame 4 is mounted on the frame 1. The two ends of the movable frame 4 move along the first linear module 3. A second linear module 5 and a cutting frame 6 are provided on the movable frame 4. The cutting frame 6 moves along the second linear module 5. The moving direction of the cutting frame 6 is perpendicular to the moving direction of the movable frame 4. A cutting tool group 12 is installed on the cutting frame 6. A cutting gap 7 is provided within the moving range of the cutting tool group 12. The cutting gap 7 is provided between two adjacent conveying rollers 2. Positioning mechanisms 8 are provided at the front end and the rear end of the cutting gap 7.

[0029] The material is conveyed by a number of conveying rollers 2 to the position of the cutting tool group 12. The first linear module 3 and the second linear module 5 respectively realize the movement of the cutting tool group 12 on the X-axis and the Y-axis. The driving devices of the first linear module 3, the second linear module 5 and the conveying rollers 2 adopt the prior art and will not be elaborated here.

[0030] The movement range of the cutting tool group 12 on the X-axis and the Y-axis is limited. The cutting area can be defined according to requirements. There is a cutting gap 7 within the cutting area. The cutting gap 7 avoids the conveying rollers 2 to prevent the conveying rollers 2 from hindering the movement of the cutting tool group 12. Positioning mechanisms 8 are provided both in front of and behind the cutting gap 7, and the number of the positioning mechanisms 8 can be adjusted according to actual production requirements.

[0031] The positioning mechanism 8 includes a first rotating motor 81, a guide seat 82, a support seat 83, a movable rod 84 and a lifting drive assembly 814. The output shaft of the first rotating motor 81 is fixedly connected under the guide seat 82. A guide hole 85 is provided in the guide seat 82, and a guide groove 86 is formed in the inner wall of the guide hole 85. The support seat 83 is arranged above the guide seat 82 and fixed on the frame 1. A movable hole 87 is formed in the support seat 83. The movable rod 84 is inserted into the movable hole 87. A limiting block 88 for preventing the movable rod 84 from escaping from the movable hole 87 is provided in the movable hole 87. The bottom of the movable rod 84 extends into the guide hole 85, and a guide rod 89 is fixed at the bottom of the movable rod 84. The guide rod 89 is inserted into and limited in the guide groove 86. The top of the movable rod 84 extends out of the movable hole 87 and is fixed with a pressing plate 810. The top of the movable rod 84 is arranged between two adjacent conveying rollers 2, and the pressing plate 810 is arranged above the conveying rollers 2. The lifting drive assembly 814 is used to drive the movable rod 84 to move up or down.

[0032] Both the first rotating motor 81 and the support seat 83 are fixed on the frame 1 with fixed positions. The guide seat 82 is fixedly connected to the output shaft of the first rotating motor 81 and can rotate under the drive of the first rotating motor 81.

[0033] When the lifting drive assembly 814 drives the movable rod 84 to move downwards, the movable rod 84 drives the pressing plate 810 to move downwards and press the edge of the material. At the same time, the guide rod 89 at the bottom of the movable rod 84 moves downwards along the guide groove 86 to prevent the movable rod 84 from shaking when moving downwards. When the first rotating motor 81 works, it drives the guide seat 82 to rotate. Since the guide rod 89 is inserted into and limited in the guide groove 86, when the guide seat 82 rotates, the guide groove 86 drives the guide rod 89 to rotate together, and then drives the movable rod 84 to rotate together, so as to realize the rotation of the pressing plate 810.

[0034] The pressing plate 810 can rotate, so the downward pressing position of the pressing plate 810 is adjustable, further increasing the moving space of the cutting tool group 12 and preventing the cutting tool group 12 from hitting the pressing plate 810. At the same time, for some special scenarios, such as when the material needs to be cut into a rounded corner or a right-angled structure, when the cutting tool group 12 is about to move to the position of the pressing plate 810, the pressing plate 810 is rotated by 90-180°, completely avoiding the cutting tool group 12. This positioning mechanism 8 can increase the cutting scenarios, making the types of cut mattresses more extensive.

[0035] The lifting drive assembly 814 includes a second rotating motor 8141, a rotating shaft 8142, a support rod 8143, a pressing wheel 8144 and a spring 8145. The second rotating motor 8141 is fixed on the frame 1, and the rotating shaft 8142 is fixedly connected to the output shaft of the second rotating motor 8141 and can be connected by a coupling or the like. The support rod 8143 is fixed on the rotating shaft 8142, and the pressing wheel 8144 is fixed at the end of the support rod 8143. When the rotating shaft 8142 drives the support rod 8143 and the pressing wheel 8144 to rotate, the pressing wheel 8144 can press the top of the pressing plate 810. By rotating the rotating shaft 8142, the pressing wheel 8144 can rotate accordingly. In this way, the pressing wheel 8144 can completely avoid the cutting area and prevent affecting the cutting.

[0036] There are multiple lifting drive assemblies 814. One positioning mechanism 8 can be equipped with one lifting drive assembly 814. Of course, one lifting drive assembly 814 can also adjust multiple positioning mechanisms 8 on the same side at the same time. It only needs to fix multiple support rods 8143 and pressing wheels 8144 on the rotating shaft 8142 of one lifting drive assembly 814.

[0037] A slider 811 is fixed on the movable rod 84. The slider 811 is arranged in the movable hole 87 and can slide along the hole wall of the movable hole 87, increasing the stability of the movable rod 84 during movement. A shoulder 812 is arranged in the movable hole 87. The top of the spring 8145 is fixed at the bottom of the slider 811, and the bottom of the spring 8145 can abut against the shoulder 812. When the pressing plate 810 loses the pressing of the pressing wheel 8144, under the action of the spring 8145, the slider 811 drives the movable rod 84 to move upward until it abuts against the limit block 88. The pressing plate 810 stops moving and returns to the position before pressing, and the pressing plate 810 releases the material. In addition, since there is no fixation between the bottom of the spring 8145 and the shoulder 812, when the movable rod 84 rotates, the spring 8145 can rotate accordingly.

[0038] The support seat 83 is arranged below the conveying roller 2. A cushion block 813 is fixed on the support seat 83. The cushion block 813 is arranged between two adjacent conveying rollers 2 and has the same height as the conveying roller 2. When the positioning mechanism 8 presses the material, the edge of the material is fixed between the pressing plate 810 and the cushion block 813, and the positioning is more stable.

[0039] The guiding grooves 86 are arranged in the vertical direction. There are multiple guiding grooves 86, and there are multiple guiding rods 89 with the same number as that of the guiding grooves 86.

[0040] A worm gear screw rod lifting assembly is provided on the cutting frame 6. The worm gear screw rod lifting assembly includes a driving mechanism 9 and a lifting screw rod 10. The driving mechanism 9 is fixed on the cutting frame 6. The lifting screw rod 10 is driven by the driving mechanism 9, and a cutting tool group 12 is fixed at the bottom of the lifting screw rod 10.

[0041] The worm gear screw rod lifting assembly is a prior art and will not be elaborated here. Driven by the driving mechanism 9, the lifting screw rod 10 can move up and down, thereby driving the cutting tool group 12 to move up and down and changing the cutting range of the cutting tool group 12.

[0042] Reference Figure 6 As shown in the figure, a third rotary motor 11 is fixed at the bottom of the lifting screw rod 10. The third rotary motor 11 can move up and down together with the lifting screw rod 10, and the output shaft of the third rotary motor 11 faces downward. The cutting tool group 12 includes a first fixing plate 121, a second fixing plate 122 and two cutting tools 123. The first fixing plate 121 is fixedly connected to the output shaft of the third rotary motor 11. The second fixing plate 122 is arranged below the first fixing plate 121. The two cutting tools 123 are symmetrically fixed between the first fixing plate 121 and the second fixing plate 122. The third rotary motor 11 can drive the cutting tools 123 to rotate, thereby realizing the change of the cutting range. When one cutting tool 123 moves to one end of the conveying roller 2, the other cutting tool 123 can be used in the next cutting scenario. The two cutting tools 123 are used alternately to improve the cutting efficiency.

[0043] A first through hole is formed in the lifting screw rod 10, a second through hole is formed in the third rotary motor 11, a sleeve 124 is fixed between the first fixing plate 121 and the second fixing plate 122, a third through hole is formed in the sleeve 124, a fourth through hole is formed in the first fixing plate 121, and a fifth through hole is formed in the second fixing plate 122. All the through holes communicate with each other to form a movable channel 13. A cylinder 14 is fixed at the top of the lifting screw rod 10. A piston rod 15 is provided at the bottom of the cylinder 14, and a drilling head 16 is fixed at the bottom of the piston rod 15. The piston rod 15 and the drilling head 16 extend into the movable channel 13, and the drilling head 16 can extend out from the fifth through hole. The cylinder 14 drives the piston rod 15 to stretch up and down, and further drives the drilling head 16 to move up and down to drill air holes, positioning holes, etc., realizing the drilling function.

[0044] Reference Figure 7, a directional conveying mechanism 17 is provided at the front end of the positioning mechanism 8. The directional conveying mechanism 17 includes a fourth rotating motor 171, a bidirectional screw 172 and two sets of conveying wheel groups. The fourth rotating motor 171 is fixed on the frame 1. The two ends of the bidirectional screw 172 are installed on the frame 1 and are arranged below the conveying roller 2 and driven by the fourth rotating motor 171. The fourth rotating motor 171 and the bidirectional screw 172 can be connected by a coupling, etc. The two sets of conveying wheel groups are respectively arranged on both sides of the bidirectional screw 172 and move bidirectionally on the bidirectional screw 172. The conveying wheel group includes a movable nut 173, a mounting frame 174 and a positioning wheel 175. The movable nut 173 is arranged on the bidirectional screw 172 and is arranged between two adjacent conveying rollers 2. The mounting frame 174 is fixed on the movable nut 173 and is arranged above the conveying roller 2. The positioning wheel 175 is rotatably arranged on the mounting frame 174.

[0045] According to the width of the material, the distance between the two sets of conveying wheel groups is adjusted. The bidirectional screw 172 realizes the synchronous bidirectional movement of the two sets of conveying wheel groups, so that the material is always in the middle position of the conveying roller 2, avoiding the frame 1 and reducing the influence of the frame 1 on cutting. At the same time, the positioning mechanism 8 can be fixed together with the conveying wheel group, so that the positioning mechanism 8 moves together with the conveying wheel group.

[0046] The directional conveying mechanism 17 includes a first deviation correction wheel group and a second deviation correction wheel group. The first deviation correction wheel group and the second deviation correction wheel group are arranged at the front end of the conveying wheel group.

The fifth rotating motor 1761 and the first screw 1762 can be connected by a coupling. The first nut 1763 is movably arranged on the first screw 1762 and is arranged between two adjacent conveying rollers 2. The first fixing frame 1764 is fixed on the first nut 1763 and is arranged above the conveying roller 2. The first deviation correction wheel 1765 is rotatably arranged on the first fixing frame 1764; the second deviation correction wheel group includes a sixth rotating motor 1771, a second screw 1772, a second nut 1773, a second fixing frame 1774 and a second deviation correction wheel 1775.

[0047] A position sensor 18 is provided at the front end of the first deviation rectifying wheel set and the second deviation rectifying wheel set, and the position sensor 18 is fixed on the frame 1.

[0048] The position sensor 18 senses the position of the material and transmits the position information to the control device. The control device controls and adjusts the first deviation rectifying wheel 1765 or the second deviation rectifying wheel 1775 according to the deviation condition of the material entry, and slowly pushes the material by using the first deviation rectifying wheel 1765 or the second deviation rectifying wheel 1775, so that the material enters the directional conveying mechanism 17 in the center.

[0049] The material is sent to the conveying roller 2. The position sensor 18 senses the position of the material. The first deviation rectifying wheel 1765 or the second deviation rectifying wheel 1775 moves according to the deviation information of the material and pushes the material to smoothly enter the directional conveying mechanism 17. The edge of the material is restricted by the positioning wheel 175 during conveying. When it is conveyed to the cutting position, the conveying roller 2 stops conveying. The positioning mechanism 8 fixes the edge of the material, adjusts the initial position and the initial angle state of the cutting tool set 12, and cuts the material. During the cutting process, different cuts are realized by adjusting the position, angle, height, etc. of the cutting tool set 12, and drilling, etc. is realized according to the requirements. Under the action of the positioning mechanism 8, the material will not deviate during cutting, and the cut is neater.

[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
