Description

Technical Field

[0001] This utility model belongs to the field of roll material cutting technology, and in particular relates to a roll material laser cutting machine with a bonding and waste removal device. Background Technology

[0002] In the field of roll material processing, laser cutting machines are widely used in roll material cutting operations in industries such as packaging, electronics, and printing due to their advantages such as high cutting precision and high efficiency.

[0003] The inventors discovered that at least the following problems remain unresolved in the existing technology: Currently, some roll material processing requires bonding two sets of roll materials of different materials or functions before laser cutting, such as composite packaging materials and flexible electronic substrates. In traditional processes, roll material bonding mostly relies on manual operation or independent bonding equipment. Manual bonding is prone to uneven force and positioning deviation, resulting in low bonding accuracy, bubbles, wrinkles, and other problems, which directly affect the subsequent cutting quality. Independent bonding equipment requires additional production space, and during the transfer of the bonded roll material to the cutting equipment, transport deviation can further reduce processing accuracy, while increasing equipment investment costs and production process complexity.

[0004] Existing waste removal methods mostly employ manual sorting or single roller conveyor waste removal. Manual sorting is inefficient, labor-intensive, and prone to damage to finished products due to human error. Single roller conveyor waste removal can only remove waste as a whole, making it difficult to achieve automatic separation of waste from finished products, requiring subsequent secondary processing and extending the production cycle.

[0005] Therefore, we propose a roll laser cutting machine with a bonding and waste removal device, which can solve the above problems. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned technical problems by providing a roll material laser cutting machine with a bonding and waste removal device, which is an integrated device that combines bonding, limiting, cutting, waste removal, and collection functions to improve the precision, efficiency, and automation level of roll material processing.

[0007] In view of this, the present invention provides a roll material laser cutting machine with a bonding waste removal device, including a cutting table and a laser cutting machine body. Two sets of connecting rods are provided on the front side of the cutting table. A roll material cylinder is detachably installed on the outer side of the connecting rods. The laser cutting machine body is slidably connected to the middle of the inner side of the cutting table via an electric slide rail.

[0008] The front side of the cutting table is provided with a bonding mechanism for bonding two sets of rolls of material.

[0009] The cutting table is equipped with a waste removal mechanism at the end away from the bonding mechanism, which is used to remove waste after the roll material is bonded and cut.

[0010] The waste discharge mechanism is equipped with a collection mechanism on its bottom side for collecting the finished products after the roll material is cut.

[0011] Furthermore, the bonding mechanism includes two sets of bonding rollers for extruding the roll material. The two sets of bonding rollers are symmetrically arranged on the side of the roll tube close to the laser cutting machine body, and the two sets of bonding rollers rotate in opposite directions. A first servo motor is fixedly connected to the outside of the cutting table. The shaft end of the first servo motor is fixedly connected to one end of the connecting rod. Two sets of second servo motors are fixedly connected to the side of the cutting table away from the first servo motor. The shaft ends of the two sets of second servo motors are respectively fixedly connected to one end of the two sets of bonding rollers.

[0012] Furthermore, a limiting component is provided on the side of the bonding mechanism near the laser cutting machine body for limiting the conveying of the rolled material after bonding. The limiting component includes a limiting rod for limiting the two sides of the rolled material. A sliding groove is provided on the upper surface of the cutting table. Two sets of sliders are slidably connected to the inner side of the sliding groove. One end of the limiting rod is fixedly connected to the middle of the upper surface of the slider. A lead screw is horizontally threaded through the middle of the slider and threadedly connected to it. The threads on both sides of the lead screw have opposite directions of rotation.

[0013] Furthermore, the lead screw is rotatably connected to the inner wall of the slide groove via a bearing, and a knob is fixedly installed at one end of the lead screw located outside the cutting table.

[0014] Furthermore, the waste removal mechanism includes a waste removal roller for conveying waste, a top rod for separating waste from products, and a cam for driving the top rod to move. A third servo motor is fixedly connected to the side of the cutting table where the second servo motor is installed. The shaft end of the third servo motor is fixedly connected to one end of the waste removal roller. A long strip housing is horizontally arranged above the side of the waste removal roller near the laser cutting machine body. A control strip is horizontally arranged inside the long strip housing. The top rod is equidistantly installed on the bottom side of the control strip. The top rod vertically penetrates the inner wall of the bottom end of the long strip housing and is slidably connected to the long strip housing. The cam abuts against the upper surface of the control strip. A drive rod is horizontally penetrated and fixedly installed in the middle of the cam. The drive rod is rotatably connected to the inner wall of the long strip housing through a bearing.

[0015] Furthermore, a spring is provided on the bottom side of the control bar, and the spring is sleeved on the outside of the top rod.

[0016] Furthermore, a large pulley is fixedly installed at the end of the waste discharge roller away from the third servo motor, and a small pulley is fixedly installed at the end of the drive rod located outside the cutting table. The large pulley is connected to the small pulley via a transmission belt.

[0017] Furthermore, the collecting mechanism includes a collecting groove horizontally opened on the upper surface of the cutting table, the bottom end of the top rod is inserted into the collecting groove, the end of the cutting table away from the roll is provided with an inclined discharge port, and the inlet end of the discharge port is connected to the bottom end of the collecting groove.

[0018] The beneficial effects of this utility model are:

[0019] 1. The bonding mechanism uses a first servo motor to drive the roll material for stable feeding, while two sets of second servo motors drive bonding rollers in opposite directions to press against each other, achieving tight bonding of the two rolls of material. This avoids the deviation and inefficiency of manual bonding, laying a high-quality foundation for subsequent cutting. The limiting component next to the bonding mechanism can adjust the lead screw by rotating the knob, driving two sets of limiting rods to adapt to composite rolls of different widths, limiting roll material deviation during conveying, and ensuring the accuracy of laser cutting. The waste removal mechanism uses a third servo motor to drive the waste removal roller to convey waste material, while simultaneously using a belt pulley to drive the cam to rotate, causing the top rod to move up and down periodically to separate the finished product from the waste material, ensuring continuous separation and avoiding waste residue. After the collection trough of the collection mechanism receives the finished product, the inclined discharge port allows the finished product to slide out automatically by gravity, achieving centralized collection and reducing manual labor.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1 to 4 A laser cutting machine for roll materials with a bonding and waste removal device includes a cutting table 1 and a laser cutting machine body 16. Two sets of connecting rods 12 are provided on the front side of the cutting table 1. A roll material cylinder 11 is detachably installed on the outer side of each connecting rod 12. The laser cutting machine body 16 is slidably connected to the middle of the inner side of the cutting table 1 via an electric slide rail 17. A bonding mechanism is provided on the front side of the cutting table 1 for bonding two sets of roll materials. A waste removal mechanism is provided at the end of the cutting table 1 away from the bonding mechanism for removing waste after the roll material is bonded and cut. A collection mechanism is provided on the bottom side of the waste removal mechanism for collecting the finished product after the roll material is cut.

[0028] During operation, two sets of roll materials are first installed on the roll drum 11 outside the connecting rod 12 on the front side of the cutting table 1 to provide raw materials for subsequent processing. Then, the roll material released from the roll drum 11 first enters the bonding mechanism to precisely bond the two sets of roll materials, forming a composite roll material. The composite roll material is then conveyed to the inner center of the cutting table 1, where the laser cutting machine body 16 moves flexibly horizontally via the electric slide rail 17, thereby performing laser cutting operations on the composite roll material at specified positions and in specified shapes. After cutting, the finished roll material with waste material continues to be conveyed to the waste removal mechanism at the end away from the bonding mechanism. The waste removal mechanism separates the waste material from the finished product and discharges the waste material. Finally, the separated finished product falls into the collection mechanism at the bottom of the waste removal mechanism, completing the collection of the finished product. The entire process is seamless and efficient, significantly improving the automation level and processing quality of roll material processing.

[0029] Furthermore, the bonding mechanism includes two sets of bonding rollers 14 for extruding the roll material. The two sets of bonding rollers 14 are symmetrically arranged on the side of the roll 11 near the laser cutting machine body 16, and the two sets of bonding rollers 14 rotate in opposite directions. A first servo motor 13 is fixedly connected to the outer side of the cutting table 1. The shaft end of the first servo motor 13 is fixedly connected to one end of the connecting rod 12. Two sets of second servo motors 15 are fixedly connected to the side of the cutting table 1 away from the first servo motor 13. The shaft ends of the two sets of second servo motors 15 are respectively fixedly connected to one end of the two sets of bonding rollers 14.

[0030] Driven by the first servo motor 13, the connecting rod 12 drives the roll drum 11 to rotate synchronously, stably conveying the roll material to the bonding roller 14. Simultaneously, two sets of second servo motors 15 on the other side of the cutting table 1 drive the corresponding bonding rollers 14 to rotate, with the two sets of bonding rollers 14 rotating in opposite directions, forming a counter-pressing motion. When the two sets of roll material enter the gap between the two sets of bonding rollers 14, under the counter-pressing action of the bonding rollers 14, the two sets of roll material are tightly bonded together to form a composite roll material.

[0031] Furthermore, a limiting component is provided on one side of the bonding mechanism near the laser cutting machine body 16 for limiting the conveying of the rolled material after bonding. The limiting component includes a limiting rod 22 for limiting the two sides of the rolled material. A sliding groove 2 is provided on the upper surface of the cutting table 1. Two sets of sliders 21 are slidably connected to the inner side of the sliding groove 2. One end of the limiting rod 22 is fixedly connected to the middle of the upper surface of the slider 21. A lead screw 23 is threaded through the middle of the slider 21 and threadedly connected to it. The threads on both sides of the lead screw 23 have opposite directions of rotation.

[0032] Because the threads on both sides of the lead screw 23 rotate in opposite directions, when the lead screw 23 is rotated, the two sets of sliders 21 threadedly connected to it on the inner side of the slide groove 2 will move towards or away from each other along the axial direction of the lead screw 23. The limiting rods 22 are fixed to the upper surface of the sliders 21, so the movement of the sliders 21 drives the two sets of limiting rods 22 to move synchronously, thereby adjusting the distance between the two sets of limiting rods 22. The operator can adjust the distance between the limiting rods 22 to match the width of the composite roll by rotating the lead screw 23. During the conveying of the composite roll, the limiting rods 22 on both sides act as a barrier, limiting the roll's horizontal deviation and ensuring that the roll always enters the cutting range of the laser cutting machine body 16 with a precise posture, thus improving the accuracy of laser cutting.

[0033] Furthermore, the lead screw 23 is rotatably connected to the inner wall of the slide groove 2 via a bearing, and a knob 24 is fixedly installed at one end of the lead screw 23 located outside the cutting table 1.

[0034] A knob 24 is fixedly installed at one end of the lead screw 23 located outside the cutting table 1. Operators can rotate the lead screw 23 simply by hand, without needing additional tools, thereby adjusting the distance between the two sets of limit rods 22. This reduces the difficulty of operation, allowing operators to quickly and conveniently adjust the limit positions for composite rolls of different widths, improving the ease of operation and work efficiency of the equipment.

[0035] Furthermore, the waste removal mechanism includes a waste removal roller 3 for conveying waste, a top rod 34 for separating waste from products, and a cam 36 for driving the top rod 34 to move. A third servo motor 31 is fixedly connected to one side of the cutting table 1 where the second servo motor 15 is installed. The shaft end of the third servo motor 31 is fixedly connected to one end of the waste removal roller 3. A long strip housing 32 is horizontally arranged above the side of the waste removal roller 3 near the laser cutting machine body 16. A control strip 33 is horizontally arranged on the inner side of the long strip housing 32. The top rod 34 is equidistantly installed on the bottom side of the control strip 33. The top rod 34 vertically penetrates the inner wall of the bottom end of the long strip housing 32 and is slidably connected to the long strip housing 32. The cam 36 abuts against the upper surface of the control strip 33. A drive rod 35 is horizontally penetrated and fixedly installed in the middle of the cam 36. The drive rod 35 is rotatably connected to the inner wall of the long strip housing 32 through a bearing.

[0036] The third servo motor 31 starts, driving the waste discharge roller 3 to rotate. During rotation, the waste discharge roller 3 generates traction force on the cut roll material, conveying the finished roll material with waste material towards the waste discharge direction. At the same time, the drive rod 35 drives the cam 36 to rotate under the action of external power. Since the cam 36 abuts against the upper surface of the control bar 33, the rotation of the cam 36 will generate a periodic downward pressure force on the control bar 33. When the protruding part of the cam 36 contacts the control bar 33, it pushes the control bar 33 to move downward along the inner side of the elongated housing 32, thereby driving the push rod 34 fixed on the bottom side of the control bar 33 to move downward synchronously. After the push rod 34 penetrates the bottom end of the elongated housing 32, it applies a pushing force to the roll material conveyed below, separating the finished product from the waste material. When the protruding part of the cam 36 rotates away from the control bar 33, the control bar 33 moves upward under the reset action of the subsequent spring 37, and the push rod 34 resets accordingly, preparing for the next push separation. The waste discharge roller 3 continuously conveys the waste material and the top rod 34 periodically pushes it together to achieve efficient separation of waste material and finished product. At the same time, the waste discharge roller 3 continuously conveys the separated waste material to the outside to complete the waste discharge operation.

[0037] Furthermore, a spring 37 is provided on the bottom side of the control bar 33, and the spring 37 is sleeved on the outside of the top rod 34.

[0038] When the protruding portion of the cam 36 presses down on the control bar 33, the control bar 33 moves downward and compresses the spring 37, which stores elastic potential energy during this process. When the protruding portion of the cam 36 rotates away from the control bar 33 and the downward pressure on the control bar 33 disappears, the spring 37 releases the stored elastic potential energy, generating an upward reset force that pushes the control bar 33 upward rapidly, thereby causing the push rod 34 to quickly reset.

[0039] Furthermore, a large pulley 4 is fixedly installed at the end of the waste discharge roller 3 away from the third servo motor 31, and a small pulley 42 is fixedly installed at the end of the drive rod 35 located outside the cutting table 1. The large pulley 4 is connected to the small pulley 42 via a transmission belt 41.

[0040] When the third servo motor 31 drives the waste discharge roller 3 to rotate, the waste discharge roller 3 drives the large pulley 4 to rotate synchronously. The large pulley 4 transmits power to the small pulley 42 through the transmission belt 41. The small pulley 42 rotates accordingly and drives the drive rod 35 to rotate synchronously, which in turn drives the cam 36 to rotate, realizing the periodic pushing action of the push rod 34. This linkage method ensures that the conveying speed of the waste discharge roller 3 matches the pushing frequency of the push rod 34, avoiding problems such as incomplete waste separation or roll material conveying jams caused by asynchronous movement of the two.

[0041] Furthermore, the collecting mechanism includes a collecting groove 38 horizontally opened on the upper surface of the cutting table 1, the bottom end of the top rod 34 is inserted into the collecting groove 38, and the end of the cutting table 1 away from the roll 11 is provided with an inclined discharge port 39, and the inlet end of the discharge port 39 is connected to the bottom end of the collecting groove 38.

[0042] During the operation of the waste removal mechanism, the top rod 34 separates the finished product from the waste material. The finished product falls into the collection groove 38 on the surface of the cutting table 1 under its own gravity. Since the end of the collection groove 38 is connected to the inlet end of the inclined discharge port 39, the finished product in the collection groove 38 will slide along the collection groove 38 towards the discharge port 39 under the action of gravity, and finally slide out of the cutting table 1 through the inclined discharge port 39. The staff can place a collection container under the discharge port 39 to collect the finished product in a convenient and quick manner.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
