Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to an automatic cutting and forming machine for insulating cardboard. Background Technology

[0002] Insulating paperboard is a special paper product with high insulation performance, high temperature resistance and mechanical strength. It is made from pure wood pulp fiber (such as sulfate wood pulp) and synthetic fiber through papermaking process. After calendering and drying, it forms a dense and uniform board material. The automatic cutting and forming machine for insulating paperboard is an automated equipment specially designed for the efficient processing of insulating paperboard. It is mainly used to cut insulating paperboard into the required length according to preset size, shape and precision requirements.

[0003] Currently, existing cutting and forming machines use specialized tools such as wrenches and sockets to tighten the fixing bolts diagonally to install the blades when changing them. However, during production, the machines cut insulating cardboard of different thicknesses, requiring the use of different blades. Manual disassembly requires loosening the fixing bolts one by one with wrenches and sockets, which is time-consuming and labor-intensive, especially when there are many bolts or when they are corroded due to long-term use. Existing technology uses integrated power tools to control the tightness of the bolts and the positioning of the blades. Through program settings, the rotation angle and torque of the power tool and servo motor are precisely controlled to ensure consistent torque during bolt disassembly and installation, avoiding uneven torque caused by human operation. However, bolts tightened later may cause slight deformation of the mounting base due to bolts tightened earlier, ultimately causing the blade positioning reference to shift, thus affecting the cutting accuracy. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic cutting and forming machine for insulating cardboard, which aims to improve the problem in the prior art where the bolts tightened later cause slight deformation of the mounting base due to the bolts tightened earlier, ultimately causing the blade positioning reference to shift and thus affecting the cutting accuracy.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an automatic cutting and forming machine for insulating paperboard, comprising a machine body, a replacement mechanism installed in the middle of the top wall of the machine body for quickly replacing blades, a rolling mechanism installed on the front top of the machine body for collecting the cut paper by rolling, and multiple arc-shaped hollow collection racks fixedly connected at equal intervals on the front outer wall of the machine body; the replacement mechanism includes a moving block installed in the middle of the top wall of the machine body, a hollow clamping block fixedly connected to the front outer wall of the moving block, a hollow elongated block provided at the bottom of the hollow clamping block, multiple inner sliding groove plates fixedly connected at equal intervals on the top inner wall of the hollow elongated block, sliding short blocks installed inside the inner sliding groove plates, and a driving assembly installed on the inner wall of the hollow elongated block.

[0006] As a further description of the above technical solution:

[0007] The drive assembly includes a motor, the output end of which is fixedly connected to a worm gear. A bidirectional threaded rod is installed on the hollow block. A worm wheel is fixedly connected to the middle of the outer wall of the bidirectional threaded rod. A support frame is fixedly connected to the middle of the top wall of the machine body. Hydraulic push rods are fixedly connected to the left and right sides of the top of the support frame. A cutting blade is installed inside the hollow clamping block.

[0008] As a further description of the above technical solution:

[0009] The rolling mechanism includes a hollow long frame, which is installed on the top front side of the machine body. An elongated fixed rod is rotatably connected inside the hollow long frame, and a roller is fixedly connected to the outer wall of the elongated fixed rod. An actuation component is installed on the top front side of the machine body.

[0010] As a further description of the above technical solution:

[0011] The execution component includes a motor, which is mounted on the top front side of the machine body. A gear is fixedly connected to the output end of the motor. A support frame is fixedly connected to the top front side of the machine body. A hollow long plate is fixedly connected to the middle of the inner wall of the support frame. A rack is slidably connected inside the hollow long plate. A connecting rod is fixedly connected to the bottom end of the rack. A motor is fixedly connected to the left end of the outer wall of the long fixed rod.

[0012] As a further description of the above technical solution:

[0013] The bottom of the connecting rod is fixedly connected to a long short plate, and the bottom of the long short plate is fixedly connected to the top of the motor.

[0014] As a further description of the above technical solution:

[0015] The gear meshes with the rack, and the right side of the outer wall of the second motor is fixedly connected to the left side of the outer wall of the hollow long frame.

[0016] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the starting motor drives the worm to rotate, and the worm meshes with the worm wheel, causing the bidirectional threaded rod to rotate. While the bidirectional threaded rod rotates, the sliding short block, under the restriction of the inner sliding groove plate, causes the moving block to move horizontally synchronously, adjusting the spacing of the hollow clamping blocks to accommodate cutting blades of different widths. Subsequently, the hydraulic push rod pushes the hollow long block to move, realizing the cutting. This avoids the problem in the prior art where the bolts tightened later cause slight deformation of the mounting base due to the bolts tightened earlier, ultimately causing the blade positioning reference to shift and affecting the cutting accuracy.

[0022] 2. In this utility model, the motor is started, driving the gear to rotate and mesh with the rack to achieve lifting and lowering, so as to adapt to insulating paperboard of different thicknesses. After the second motor is started, the long fixed rod rotates, and the roller rotates accordingly. The cut insulating paperboard is contacted and transported to the collection rack for storage through rolling friction. Attached Figure Description

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.

[0032] Reference Figure 2 , Figure 3 and Figure 4This utility model provides an embodiment of an automatic cutting and forming machine for insulating paperboard, comprising a machine body 1. A replacement mechanism 2 is installed in the middle of the top wall of the machine body 1 for quickly replacing blades. A rolling mechanism 3 is installed on the front top of the machine body 1 for collecting the cut paper. Multiple arc-shaped hollow collection racks 5 are fixedly connected at equal intervals on the front outer wall of the machine body 1. The replacement mechanism 2 includes a moving block 201, which is installed in the middle of the top wall of the machine body 1. A hollow clamping block 202 is fixedly connected to the front outer wall of the moving block 201. A hollow elongated block 203 is provided at the bottom of the hollow clamping block 202. Multiple inner sliding plates 204 are fixedly connected at equal intervals on the top inner wall of the hollow elongated block 203. Sliding short blocks 205 are installed inside the inner sliding plates 204. There is a drive assembly 206, which includes a motor 2061. The output end of the motor 2061 is fixedly connected to a worm gear 2062. A double-threaded rod 2063 is installed on the hollow long block 203. A worm wheel 2064 is fixedly connected to the middle of the outer wall of the double-threaded rod 2063. A support frame 2065 is fixedly connected to the middle of the top wall of the machine body 1. Hydraulic push rods 2066 are fixedly connected to the top left and right sides of the support frame 2065. A cutting blade 2067 is installed inside the hollow clamping block 202. A long short plate 3042 is fixedly connected to the bottom of the connecting rod 3048. The connecting rod 3048 serves to fix and support the long short plate 3042. The bottom of the long short plate 3042 is fixedly connected to the top of the motor 3041. The long short plate 3042 serves to fix and support the motor 3041.

[0033] Specifically, after the motor 2061 is started, it drives the worm 2062 to rotate. The worm 2062 meshes with the worm wheel 2064 in the middle of the double-threaded rod 2063, thereby driving the double-threaded rod 2063 to rotate. When the double-threaded rod 2063 rotates, it drives the two moving blocks 201 on the outer wall and the hollow clamping block 202 to move synchronously. The sliding short block 205 is restricted by the inner sliding plate 204. The moving blocks 201 move synchronously closer or further away in the horizontal direction, adjusting the distance between the two hollow clamping blocks 202 to accommodate cutting blades 20 of different widths. 67. The clamping installation is performed. The two hydraulic push rods 2066 on the top of the support frame 2065 extend or retract simultaneously, pushing the hollow long block 203 to move. When the hollow long block 203 moves downward, it drives the clamped cutting blade 2067 to cut downward. The bottom of the connecting rod 3048 is fixedly connected to the long short plate 3042. The connecting rod 3048 plays the role of fixing and supporting the long short plate 3042. The bottom of the long short plate 3042 is fixedly connected to the top of the motor 3041. The long short plate 3042 plays the role of fixing and supporting the motor 3041.

[0034] Reference Figure 1 , Figure 5 and Figure 6The rolling mechanism 3 includes a hollow elongated frame 301, which is mounted on the top front side of the machine body 1. An elongated fixed rod 303 is rotatably connected inside the hollow elongated frame 301, and a roller 302 is fixedly connected to the outer wall of the elongated fixed rod 303. An actuation assembly 304 is mounted on the top front side of the machine body 1, including a motor 3041. The motor 3041 is mounted on the top front side of the machine body 1, and a gear 3045 is fixedly connected to the output end of the motor 3041. A support frame 3046 is fixedly connected to the top front side of the machine body 1. A hollow long plate 3043 is fixedly connected to the middle of the inner wall of the device. A rack 3044 is slidably connected inside the hollow long plate 3043. A connecting rod 3048 is fixedly connected to the bottom end of the rack 3044. A gear 3045 meshes with the rack 3044. By rotating the gear 3045 and meshing with the rack 3044, the rack 3044 can be driven to move up and down for adjustment. The right side of the outer wall of the second motor 3047 is fixedly connected to the left side of the outer wall of the hollow long frame 301. The hollow long frame 301 can support and fix the second motor 3047 for use.

[0035] Specifically, after the motor 3041 is started, it drives the gear 3045 at the output end to rotate. The gear 3045 meshes with the rack 3044, converting the rotational motion into the linear sliding of the rack 3044. When the rack 3044 moves up and down, it drives the motor 3041, gear 3045, and roller 302 to rise and fall synchronously to adapt to insulating cardboard of different thicknesses. Then, the second motor 3047 is turned on to drive the elongated fixed rod 303 to rotate. The roller 302 on the outer wall of the elongated fixed rod 303 rotates synchronously with the rod, and the roller moves along with the rod. The cut insulating cardboard is conveyed along the conveyor to the arc-shaped hollow collection rack 5 on the front side of the machine body 1 for storage. Gear 3045 and rack 3044 are meshed and connected. By rotating gear 3045 and meshing with rack 3044, rack 3044 can be driven to move up and down. The right side of the outer wall of motor 2 3047 is fixedly connected to the left side of the outer wall of hollow long frame 301. Hollow long frame 301 can support and fix motor 2 3047 for use.

[0036] Reference Figure 3 , Figure 5 and Figure 6The interior of the movable block 201 is threadedly connected to the outer wall of the bidirectional threaded rod 2063. The rotation of the bidirectional threaded rod 2063 can drive the movable block 201 to move and adjust. The worm 2062 is meshed with the worm wheel 2064. When the worm 2062 rotates, it meshes with the worm wheel 2064, which can drive the worm wheel 2064 to rotate synchronously. The bottom of the sliding short block 205 is fixedly connected to the top of the movable block 201. The sliding short block 205 can restrict the movable block 201 and ensure that the movable block 201 can move smoothly without rotating. The left and right ends of the outer wall of the bidirectional threaded rod 2063 are rotatably connected to the interior of the hollow long block 203. The hollow long block 203 can support the bidirectional threaded rod 2063 to rotate.

[0037] Specifically, the interior of the movable block 201 is threadedly connected to the outer wall of the bidirectional threaded rod 2063. The rotation of the bidirectional threaded rod 2063 drives the movable block 201 for movement and adjustment. The worm 2062 is meshed with the worm wheel 2064. When the worm 2062 rotates, it meshes with the worm wheel 2064, enabling the worm wheel 2064 to rotate synchronously. The bottom of the sliding short block 205 is fixedly connected to the top of the movable block 201. The sliding short block 205 restricts the movable block 201, ensuring that the movable block 201 can move smoothly without rotating. The left and right ends of the outer wall of the bidirectional threaded rod 2063 are rotatably connected to the interior of the hollow long block 203. The hollow long block 203 supports the bidirectional threaded rod 2063 for rotation.

[0038] Working principle: After the motor 2061 is started, it drives the worm 2062 to rotate. The worm 2062 meshes with the worm wheel 2064 in the middle of the double-threaded rod 2063, thereby driving the double-threaded rod 2063 to rotate. When the double-threaded rod 2063 rotates, it drives the two moving blocks 201 on the outer wall and the hollow clamping block 202 to move synchronously. The sliding short block 205 is restricted by the inner sliding plate 204. The moving blocks 201 move closer or further away in the horizontal direction, adjusting the distance between the two hollow clamping blocks 202 to accommodate cutting blades 2067 of different widths for clamping and installation. The two hydraulic push rods 2066 on the top of the support frame 2065 extend or retract synchronously, pushing the hollow long block 203 to move. When the hollow long block 203 moves downward, it drives the clamped cutting blade 2067 to cut downward, thus avoiding the problem in the prior art where the bolts tightened later cause slight deformation of the mounting base due to the bolts tightened earlier, resulting in the blade positioning reference shifting and affecting the cutting accuracy.

[0039] After the motor 3041 is started, it drives the gear 3045 at the output end to rotate. The gear 3045 meshes with the rack 3044, converting the rotational motion into the linear sliding of the rack 3044. When the rack 3044 moves up and down, it drives the motor 3041, gear 3045 and roller 302 to rise and fall synchronously to adapt to insulating paperboards of different thicknesses. Then, the motor 3047 is turned on to drive the long fixed rod 303 to rotate. The roller 302 on the outer wall of the long fixed rod 303 rotates synchronously with the rod. Through rolling friction, it contacts the cut insulating paperboard and transports the cut paperboard to the arc-shaped hollow collection rack 5 on the front side of the machine body 1 for storage.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
