[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] See Figure 1-13 A refrigerator door liner die-cutting roll feeding and forming machine is characterized by comprising: a feeding trolley translation mechanism arranged sequentially along the material transport direction, capable of providing raw material rolls; an infrared heating mechanism capable of heating the raw material; a die forming mechanism capable of processing and forming the heated raw material; the die forming mechanism is further provided with a lower die linkage lifting mechanism for driving the lower die to rise and fall; a cantilever clamping mechanism capable of outputting the formed raw material; and a waste cutting and collection mechanism capable of cutting and collecting waste material from the roll.

[0053] The trolley translation mechanism has the following features:

[0054] The frame 1101 is the foundation of the entire device, and the frame 1101 can move back and forth on the ground rail 11012.

[0055] Uprights 1102 are mounted on the frame 1101. Two sets of uprights 1102 are provided on each upright, each set including two opposing uprights 1102. A material support 1103 is mounted on the uprights 1102. The uprights 1102 and the material support 1103 support the material rod 1104. The material rod 1104 is rotatably mounted on the material support 1103 and supports the material roll. By setting two sets of uprights 1102 and material rods 1104, two sets of material rolls can be supported. After one set of material rolls is used up, another set can be quickly switched to. The used material roll can then be replaced without affecting production, effectively reducing downtime caused by material roll replacement and increasing output per unit time.

[0056] A drive shaft 1107 and a driven shaft 11010 are rotatably mounted on the front and rear ends of the frame 1101; a traveling wheel 1106 is mounted on the drive shaft 1107 and the driven shaft 11010; a ground rail 11012 is set on the ground, and the traveling wheel 1106 can move on the ground rail 11012, driving the frame 1101 to move back and forth on the ground rail 11012; a drive mechanism can drive the drive shaft 1107 to rotate. By driving the drive shaft 1107 and the driven shaft 11010 to rotate through the drive mechanism, the traveling wheel 1106 moves on the ground rail 11012, thereby realizing the switching of material rolls.

[0057] The drive mechanism includes a drive motor 1109, a drive chain, and a drive sprocket. The drive sprocket is fixedly connected to the drive shaft 1107. The drive motor 1109 is mounted on the frame 1101, and the drive chain connects the drive motor 1109 and the drive sprocket. The drive motor 1109 drives the drive shaft 1107 to rotate, thereby causing the traveling wheels 1106 on the drive shaft 1107 to travel on the ground track 11012.

[0058] It also has a transmission mechanism that connects the drive shaft 1107 and the driven shaft 11010. The transmission mechanism is a transmission chain 1108 that connects the drive shaft 1107 and the driven shaft 11010. It can transmit the power of the drive shaft 1107 to the driven shaft 11010, driving the drive wheel 1106 of the driven shaft 11010 to rotate.

[0059] The material support 1103 is also equipped with a wear-resistant block 11031, and the material rod 1104 is rotatably placed on the wear-resistant block 11031. Since the material rod 1104 needs to rotate during the feeding process, the wear-resistant block 11031 can improve the wear resistance.

[0060] The ground rail 11012 is provided with limit blocks 11013 at both ends of the limit frame 1101, which serve as the end point of the movement of the limit frame 1101.

[0061] The frame 1101 is also equipped with a tensioning sprocket 11011 that can tension the transmission chain 1108, thus serving the function of tensioning the transmission chain 1108.

[0062] This mechanism is a translational mechanism for a loading trolley of a refrigerator door liner forming machine. The trolley is driven by a variable frequency motor and a chain sprocket to move horizontally on the ground rail 11012. Specific operating procedures: Before production, the worker steps onto the checkered steel plate platform to remove the material rod 1104, threads the material coil onto the material rod 1104, and then places it back on the material support seat 1103. The worker leaves the trolley and presses the trolley drive button. If the left-side material coil is used, the trolley is driven to the right limit position; if the right-side material coil is used, the trolley is driven to the left limit position. The middle position of the ground rail 11012 is the central axis of the equipment, i.e., the uncoiling and loading position. In actual production, when one roll of material is almost used up, a new roll can be simultaneously replaced on the other material rod 1104 side. After the material in the middle position is used up, the trolley is driven to achieve rapid switching between the two rolls, effectively reducing downtime caused by changing rolls and increasing output per unit time.

[0063] After the material sheet is used up, the drive trolley enables rapid switching between two material rolls, effectively reducing downtime caused by changing material rolls and increasing output per unit time.

[0064] The infrared heating mechanism is further equipped with a feeding and cutting mechanism at its front end, which can cut off the damaged parts of the rolled material. The feeding and cutting mechanism includes: a feeding frame 101, which is the mounting base of the entire device; a moving crossbeam 102, which is slidably mounted on the feeding frame 101; and a clamping assembly, which is mounted on the moving crossbeam 102 and can clamp the material. The clamping assembly clamps the material, providing a fixing function and facilitating the cutting of the material by the cutter. A conveying cylinder 103 is fixedly mounted on the moving crossbeam 102. The piston rod of the conveying cylinder 103 is connected to the feeding frame 101. The conveying cylinder 103 can drive the moving crossbeam 102 to move on the feeding frame 101. By moving the moving crossbeam 102 through the conveying cylinder 103, the pressing cylinder and the entire material sheet are conveyed forward.

[0065] The upper cutter 106 is fixedly mounted on the feed frame 101; the lower cutter is slidably mounted on the feed frame 101, and the lower cutter can be adapted to the upper cutter 106 to cut materials; the drive mechanism can drive the lower cutter to slide. The lower cutter can be adapted to the upper cutter 106 to cut materials, thus performing the cutting function.

[0066] The clamping assembly includes an upper pressing cylinder 104 and a lower pressing cylinder 105, which are mounted on a moving crossbeam 102, allowing material to pass between them. The material is compressed and clamped by the upper pressing cylinder 104 and the lower pressing cylinder.

[0067] The driving mechanism is a lower cutter lifting cylinder 108, which is fixedly mounted on the feed frame 101. The piston rod of the lower cutter lifting cylinder 108 is connected to the lower cutter. The lower cutter is driven by the lower cutter lifting cylinder 108 to move and cooperate with the upper cutter 106 to cut the material.

[0068] Both the upper pressing cylinder 104 and the lower pressing cylinder have pressure heads on their piston rods. The pressure heads are made of nylon and serve to protect the materials.

[0069] The feed frame 101 is also equipped with a waste discharge chute 1010 to guide the waste material and facilitate the discharge of the waste material.

[0070] The lower cutter is also equipped with a material discharge spring 109 that squeezes the material, which serves to break the waste material.

[0071] Brief structural description: Upper and lower pressing cylinders extend to press the material sheet firmly. Lower cutter lifting cylinder extends, causing the lower cutter to rise and cut the material sheet. Waste material enters the waste bin through the discharge chute. The forward conveying cylinder retracts, driving the pressing cylinder and the entire material sheet forward. After being conveyed to the cutter, the material sheet is easily picked up by the next station. It cuts off damaged portions of the rolled material or the joint between two rolls.

[0072] It can automatically feed materials and cut off waste materials, resulting in high work efficiency.

[0073] The lower die linkage lifting mechanism has the following features:

[0074] The third link 605 is slidably and vertically mounted on the frame; the fourth link 606 has its first end hinged to the end of the third link 605; the fifth link 607 has its middle portion hinged to the second end of the fourth link 606; the first fixed seat 6010 is fixedly mounted on the frame; the first end of the fifth link 607 is hinged to the first fixed seat 6010; the sixth link 608 has its first end hinged to the second end of the fifth link 607; the connecting seat 609 is fixedly connected to the mold table; the second end of the sixth link 608 is hinged to the connecting seat 609; the connecting seat 609 serves to fix the second end of the sixth link 608. The lifting and lowering movement of the third link 605 drives the fourth link 606 to push the fifth link 607, which in turn pushes the sixth link 608. The sixth link 608 then drives the connecting seat 609 at its end to lift and lower, and the connecting seat 609 connects to the lower mold, thus realizing the lifting and lowering of the lower mold. By using such a linkage mechanism for interconnection, when the lower die moves to its highest position, the fifth link 607 and the sixth link 608 can form a straight line, such as... Figure 7 As shown, it achieves the purpose of self-locking, and can automatically lock when it rises to the highest point to prevent loosening and loose mold closing.

[0075] It also has a drive mechanism that can drive the third link 605 to rise and fall. The drive mechanism drives the movement of the third link 605.

[0076] The drive mechanism has a drive shaft 602, a first connecting rod 603, and a second connecting rod 604. The drive shaft 602 is rotatably mounted on the frame. The first end of the first connecting rod 603 is fixedly connected to the drive shaft 602, and the first end of the second connecting rod 604 is hinged to the second end of the first connecting rod 603. The second end of the second connecting rod 604 is hinged to a third connecting rod 605. The drive mechanism converts the rotational motion of the drive shaft 602 into the lifting motion of the third connecting rod 605, causing the third connecting rod 605 to rise and fall. A servo motor drives the rotating shaft, and multiple sets of linkage mechanisms transmit power to raise and lower the lower mold table. The lifting position of the mold table is controlled by the servo motor.

[0077] It also features a guide mechanism for guiding the lifting and lowering of the third link 605. The guide mechanism includes a second fixed seat 6011, a guide post 6012, and a guide sleeve 6013. The second fixed seat 6011 is fixedly mounted on the frame, and the guide post 6012 is fixedly mounted on the second fixed seat 6011. The guide sleeve 6013 is disposed on the third link 605 and slides on the guide post 6012. This serves a guiding function, ensuring that the third link 605 maintains its predetermined lifting and lowering direction.

[0078] It also has a bearing housing 601, which is fixedly mounted on the frame, and the drive shaft 602 is rotatably mounted on the bearing housing 601. It provides a mounting base for the drive shaft 602.

[0079] The second end of the second link 604 is hinged to the middle of the third link 605. The fifth link 607 and the first fixed seat 6010 are hinged by a pin 6014, ensuring stable and reliable operation.

[0080] The lifting and lowering movement of the third link 605 drives the fourth link 606 to move the fifth link 607, which in turn drives the sixth link 608. The sixth link 608 then moves its end connecting seat 609 up and down, connecting seat 609 connecting to the lower mold, thus realizing the lifting and lowering of the lower mold. This linkage mechanism ensures that when the lower mold reaches its highest position, the fifth link 607 and the sixth link 608 form a straight line, achieving self-locking. Upon reaching the highest point, it automatically locks, preventing loosening and incomplete mold closing.

[0081] The lower mold lifting mechanism is stable and reliable, and it can automatically lock when it reaches the highest point to prevent loosening or loose mold closing.

[0082] The cantilever clamp mechanism has the following features:

[0083] The frame is equipped with: an adjustable width control device; a lifting device; a conveyor for transporting workpieces; and a clamping device for gripping workpieces. It is used for removing the door insert after in-mold cutting at the forming station and feeding it into the output conveyor belt. The clamping device is fixed to the clamping conveyor via linear guides and a slider. A servo motor on the clamping conveyor drives a synchronous belt structure to control the horizontal movement of the clamping device. The clamping conveyor is fixed to a lifting drive device, and a lifting servo motor drives a ball screw nut mechanism for lifting. A horizontal width adjustment drive motor drives the lifting structure and clamping device together to adjust the width. This mechanism allows the clamp to move in three directions (X, Y, and Z). The structure is compact and simple, optimizing equipment cycle time, increasing equipment output, and reducing the overall line length.

[0084] The width adjustment device includes: a linear guide rail mounted on the frame; a linear slide mounted on the linear guide rail; a lifting device mounted on the linear slide; and a width drive mechanism capable of driving the linear slide to slide on the linear guide rail.

[0085] The lifting device includes: a lifting seat, which is slidably mounted on a linear slide; a lifting drive motor, which is fixedly mounted on the linear slide; a lifting screw, which is connected to the rotating shaft of the lifting drive motor; and a lifting nut adapted to the lifting screw is fixedly provided on the lifting seat.

[0086] The conveying device includes: a conveyor frame, fixedly mounted on a lifting seat; a conveyor belt, rotatably mounted on the conveyor frame, with pulleys on both sides of the conveyor belt; a clamping device fixedly mounted on the conveyor belt; and a conveyor motor, connected to the pulleys and capable of driving the pulleys to rotate.

[0087] The clamping and material handling device includes: a clamping bracket, which is fixedly installed on the conveyor belt; a clamping beam, which is fixedly connected to the clamping bracket; and clamps, on which a series of clamps are provided, which can clamp the workpiece.

[0088] The width-narrowing drive mechanism includes an adjusting screw and a width-narrowing adjustment motor. The width-narrowing adjustment motor is mounted on the frame, and the adjusting screw is connected to the rotating shaft of the width-narrowing adjustment motor. The linear slide is equipped with a nut that matches the adjusting screw.

[0089] The conveying device also includes a guiding mechanism; the guiding mechanism includes a conveying guide rail, which is fixedly installed on the conveying frame, and a slider that can slide on the conveying guide rail is provided on the clamp bracket.

[0090] The width adjustment device includes two sets of linear slides and a width drive mechanism; each linear slide is equipped with a lifting device, a conveying device and a clamping device.

[0091] The clamping device is equipped with a clamping cylinder that can drive the clamp to open or close.

[0092] Operation flow: After the in-mold cutting at the molding station is completed, the clamping device opens, the lifting drive moves inward to the correct position, rises to the correct position, the clamp closes to clamp the door panel, the servo motor drives the clamping device to deliver the material to the top of the discharge conveyor belt, the lifting drive descends, the clamp opens, the lifting drive moves outward to the correct position, the door panel falls onto the conveyor belt, the lifting device rises to the correct position, and waits to enter the next cycle.

[0093] The lifting structure and clamping device are driven by a horizontal width adjustment drive motor to adjust the width together. This mechanism can meet the movement of the clamp in three directions (XYZ). The structure is compact and simple, optimizes the equipment cycle time, increases equipment output, and saves the length of the entire production line.

[0094] The waste cutting and collection mechanism includes: a frame 31, on which are: an inlet guide device 32 for introducing waste into the frame 31; a pressing device 33 for pressing the waste; a feeding device 34 for conveying the waste; a cutting mechanism 35 for cutting the waste; an outlet guide device 36 for guiding the cut waste; and a waste collection box 37 for collecting the cut waste. Waste is introduced into the frame 31 through the inlet guide device 32, the pressing device 33 presses the waste, and the pressing device 33 and the feeding device 34 work together to convey the waste to the cutting mechanism 35. The cutting mechanism 35 cuts the waste, and the cut waste is guided into the waste collection box 37 through the outlet guide device 36, thus completing the automatic cutting and collection of the separated refrigerator door liner waste.

[0095] The inlet guiding device 32 is a guide plate, which can support and guide the waste material. It plays a supporting and guiding role.

[0096] The pressing device 33 includes: a pressing shaft 331, rotatably mounted on the frame 31; a pressing swing arm 332, the first end of which is fixedly connected to the pressing shaft 331; a pressing roller 333, rotatably mounted on the second end of the pressing swing arm 332; and a pressing drive mechanism, capable of driving the pressing swing arm 332 to swing, thereby driving the pressing roller 333 to press or release the waste material. By driving the pressing swing arm 332 to swing through the pressing drive mechanism, thereby driving the pressing roller 333 to press or release the waste material, the device functions as a waste material plate.

[0097] The feeding device 34 includes a feeding motor 341 and a feeding roller 342. The feeding roller 342 is rotatably mounted on the frame 31, and the shaft of the feeding motor 341 is connected to the feeding roller 342. The feeding roller 342 can cooperate with the pressure roller 333 to press and convey waste material. Both the feeding roller 342 and the pressure roller 333 can rotate, and the feeding roller 342 can cooperate with the pressure roller 333 to press and convey waste material, thus playing a conveying role.

[0098] The cutting mechanism 35 includes: a cutting bracket 351 mounted on a bracket; a support plate 352 mounted on the cutting bracket 351, which supports waste material; a lower cutting blade 353 fixedly mounted on the support plate 352; an upper cutting blade 354 slidably mounted on the cutting bracket 351, which cooperates with the lower cutting blade 353 to cut the waste material; and a cutting drive mechanism that drives the upper cutting blade 354 to move. The cutting drive mechanism drives the upper cutting blade 354 to move downwards, cooperating with the lower cutting blade 353 below to cut the waste material.

[0099] The outlet guiding device 36 is a guiding plate, which can guide the cut waste material into the waste collection box 37 below.

[0100] The pressing drive mechanism is a pressing cylinder 334. The cylinder seat of the pressing cylinder 334 is hinged to the frame 31, and the piston rod of the pressure cylinder is hinged to the pressing swing arm 332. The pressing cylinder 334 drives the pressing swing arm 332 to swing, thereby realizing the function of pressing or releasing the waste material.

[0101] The cutting drive mechanism includes a cutter connecting rod 356 and an eccentric wheel 357, which is rotatably mounted on the cutter bracket 351. The first end of the cutter connecting rod 356 is hinged to the upper cutter 354, and the second end is hinged to the disc surface of the eccentric wheel 357. The rotation of the eccentric wheel 357 drives the cutter connecting rod 356 to reciprocate, thereby realizing the up-and-down reciprocating motion of the upper cutter 354. A guide rail is also provided on the cutter bracket 351, and the upper cutter 354 is slidably mounted on the guide rail, providing stable guidance.

[0102] The cutter bracket 351 is also equipped with a turntable drive motor that drives the eccentric wheel 357 to rotate. The turntable drive motor drives the eccentric wheel 357 to rotate, which drives the cutter connecting rod 356 to reciprocate, driving the upper cutter 354 to move downward, and cooperates with the lower cutter 353 below to cut the waste material.

[0103] Process flow: (The waste material is a continuous roll. The waste material end needs to be manually introduced into the pressing device 33 through the feed port the first time. After that, it is automatically fed.) After the waste material is pressed by the pressing device 33 (the pressing roller is driven by a cylinder), the feeding device 34 (the feeding roller is driven by a motor) automatically feeds the waste material. When the waste material enters the cutter head at a set distance (a certain length), the upper cutter 354 moves down (motor + eccentric wheel 357 + linear guide) to cut the waste material. The cut waste material slides down into the waste box by itself through the outlet guide device 36.
