Description

Technical Field

[0001] The present invention relates to the technical field of film cutting equipment, and in particular to a production equipment for laser cutting of film-coated coils. Background Art

[0002] The film is covered with a laser layer by gluing and pressing to form a laser film. After the laser film is formed and produced, it may need to be cut into sections and fixed lengths according to customer needs. This will require a production equipment for roll film coating and laser cutting.

[0003] Before using the cutting equipment, the film roll needs to be positioned on the film roll holder and the film roll needs to be braked to a certain extent to avoid the film roll lacking the necessary braking and deceleration when the film conveying mechanism stops intermittently. Under the action of the traction inertia force, the film continues to rotate and unwind without being able to stop in time, causing the film to loosen and accumulate between the film conveying mechanism and the film roll, and cannot be kept in a tensioned state, affecting the precise length determination and transportation of the film in the subsequent process, and reducing the cutting accuracy of the film;

[0004] Most of the existing cutting equipment lacks a synchronous drive mechanism between the film roll positioning mechanism and the braking mechanism, resulting in the two operations of film roll positioning and braking needing to be performed manually step by step in each cutting operation. The operation is cumbersome and inconvenient, which indirectly reduces the overall production efficiency of the cutting equipment. Summary of the Invention

[0005] In view of this, the present invention provides a production device for coil film coating and laser cutting to solve the problem that most of the film roll positioning mechanisms and brake mechanisms lack a synchronous drive mechanism.

[0006] The technical solution proposed by the present invention is: a production equipment for coil film coating and laser cutting, specifically comprising two symmetrical and fixed positioning sleeves, with a laser film roll placed between the two positioning sleeves;

[0007] A centering shaft is slidably installed in the positioning sleeve, a vertical transmission rod is welded to the bottom of the centering shaft, and a threaded sleeve is welded to the bottom end of the vertical transmission rod; semicircular supporting rings are symmetrically welded on the opposite end parts of the two positioning sleeves, and an arc-shaped through-groove is provided on the semicircular supporting rings, and an arc-shaped brake plate is slidably installed in the arc-shaped through-groove, and when the arc-shaped brake plate slides upward, it comes into contact with one end part of the reel of the laser film roll; a U-shaped limit frame is welded and hoisted on the bottom of the semicircular supporting ring and the positioning sleeve, and the U-shaped limit frame A sliding sleeve is slidably installed on the transverse side rod in the form of a spring push, the upright transmission rod is slidingly matched with the transverse side rod, and a connecting rod is rotatably connected between the sliding sleeve and the arc-shaped brake plate; the two end parts of the reel are supported and clamped in two semicircular supporting rings, and the head ends of the two centering shafts are correspondingly plugged into and matched with the two end parts of the reel; a transverse drive shaft is rotatably arranged under the positioning sleeve, and two sections of counter-rotating threads are symmetrically opened on the transverse drive shaft, and the two sections of threads are correspondingly engaged with the two threaded sleeves.

[0008] Furthermore, in the initial state, a distance is maintained between the vertical transmission rod and the sliding sleeve, and when the vertical transmission rod slides toward the arc-shaped brake plate, it abuts against the sliding sleeve;

[0009] A strip-shaped sliding groove is provided through the bottom of the peripheral wall of the positioning sleeve, and the vertical transmission rod is slidably matched with the strip-shaped sliding groove.

[0010] Furthermore, the spring for pushing the sliding sleeve is sleeved on the horizontal side rod of the C-shaped limit frame, and the compression clamp is placed between the sliding sleeve and an upright side rod of the C-shaped limit frame.

[0011] Furthermore, two U-shaped mounting frames are symmetrically welded to the bottom of the semicircular support ring, and a U-shaped sliding frame is welded to the bottom of the arc-shaped brake plate, and the U-shaped sliding frame penetrates and slides with the two U-shaped mounting frames;

[0012] The tail end of the connecting rod is rotatably connected to the outer periphery of the sliding sleeve, and the head end is rotatably connected to the U-shaped sliding frame;

[0013] A curved brake pad is fixed to the inner periphery of the curved brake plate via Velcro. When the curved brake plate abuts against the reel, the curved brake pad is squeezed between the curved brake plate and the reel.

[0014] Furthermore, the invention also includes two symmetrically arranged frames, each frame consisting of a longitudinal contact plate and two vertical support plates symmetrically welded to the top of the longitudinal contact plate, and two rubber-coated conveying rollers are symmetrically mounted between the top portions of the four vertical support plates on the two frames.

[0015] Two lifting frames are symmetrically and slidably mounted on the top portion of the four vertical support plates. The lifting frames are composed of two symmetrically arranged sliding assemblies and two longitudinal connecting rods symmetrically welded therebetween.

[0016] The sliding assembly is composed of two symmetrically arranged vertical connecting rods, a shaft ring welded between the top ends of the two rods, and a rectangular sliding sleeve welded between the bottom ends of the two rods. The rectangular sliding sleeve is in sliding cooperation with the top end of the vertical support plate.

[0017] Furthermore, two rubber-coated conveying rollers are symmetrically mounted between the four shaft rings, and the two rubber-coated conveying rollers are in sliding and extruding contact with the two rubber-coated conveying rollers on the lower side;

[0018] The same end of the four rubber-coated conveyor rollers is fixedly provided with a driving gear, and the four driving gears are arranged in pairs and meshed with each other up and down, and the other ends of the two rubber-coated conveyor rollers on the lower side are provided with sprockets;

[0019] An installation component is welded between the two vertical support plates of the frame. The installation component consists of an intermediate installation ring and two connecting short plates symmetrically welded to the outer circumference of the intermediate installation ring. A drive assembly is fixedly installed on the intermediate installation ring. A sprocket is fixedly mounted on the head end of the power output shaft of the drive assembly. A drive chain arranged in a triangle is tensioned and installed between the three sprockets.

[0020] Furthermore, a longitudinal mounting plate is welded between the top ends of the two vertical support plates on the frame, a threaded propulsion shaft is rotatably installed through the middle portion of the longitudinal mounting plate, and the threaded propulsion shaft is threadedly screwed into the two longitudinal connecting rods of the lifting frame;

[0021] The bottom ends of the two threaded propulsion shafts are fixedly sleeved with transmission sprockets, and a transmission chain is tensionedly installed between the two transmission sprockets.

[0022] Furthermore, two longitudinal supporting plates are symmetrically welded to the top parts of the two vertical supporting plates symmetrically arranged in the transverse direction on the two frames, and a material receiving plate is welded to the top sides of the two longitudinal supporting plates, and two vertical guide plates are symmetrically welded to the tail parts thereof, and a U-shaped knife holder is slidably mounted on the two vertical guide plates, and a horizontal force-bearing plate is fixedly mounted on the top part of the cutter;

[0023] Two L-shaped reinforcements are symmetrically welded between the two longitudinal support plates and the two vertical support plates at the corresponding positions. The U-shaped tool holder slides through the two L-shaped reinforcements in the form of spring push;

[0024] Two transverse reinforcement plates are symmetrically welded between the four vertical support plates. A power unit is fixedly installed on one of the transverse reinforcement plates. A driving member is fixedly installed on the power output shaft of the power unit. When the driving member rotates with the power output shaft, it comes into contact with the U-shaped tool holder.

[0025] An L-shaped support plate is welded between the two vertical guide plates. The laser film transported to the cutter via the rubber-coated conveyor roller is supported on the top horizontal part of the L-shaped support plate.

[0026] The present invention provides a production equipment for coiled material lamination and laser cutting, which has the following beneficial effects:

[0027] 1. When the two ends of the reel are clamped in the two semicircular support rings, they are coaxially aligned with the positioning sleeves. At this time, the head ends of the two centering shafts can be directly plugged into the two end parts of the reel to position the laser film roll. This can save the trouble of calibrating and aligning the reel and the positioning sleeves every time the laser film roll is installed and positioned, and the operation is convenient and time-saving.

[0028] The arc brake plate and the arc brake pad are squeezed between the arc brake plate and the reel, and the reel can be frictionally braked, which can avoid the reel lacking the necessary brake deceleration, resulting in the intermittent stop of the rubber conveying rollers. Under the action of the traction inertia of the laser film, the laser film roll continues to rotate for multiple circles and cannot follow up the stop in time, causing the laser film to accumulate unnecessary unwinding between the rubber conveying roller and the laser film roll, and cannot be kept in a tensioned state, affecting the precise conveying of the laser film by the rubber conveying roller in the subsequent process, and reducing the fixed-length cutting accuracy of the laser film; when the arc brake plate and the arc brake pad slide down and separate from the reel, space can be left inside the semicircular support ring for the reel to be tightly clamped, avoiding the arc brake plate and the arc brake pad protruding from the interior of the semicircular support ring, and lifting the reel of the newly replaced laser film roll, causing the reel to be unable to align with the positioning sleeve when clamped in the semicircular support ring.

[0029] Third, through the power transmission of two sets of crank slider mechanisms and the reverse thrust effect of the springs on the two U-shaped limit frames, the insertion, locking and extraction unlocking operations of the two centering shafts and the upward braking and downward sliding operations of the two arc-shaped brake plates can be driven and executed at one time by a common horizontal drive shaft. This can eliminate the trouble of manually performing the above two operations step by step before and after disassembling and replacing the laser film roll, help simplify the disassembly and replacement steps of the laser film roll, and indirectly improve the operational efficiency of the production equipment.

[0030] Fourth, through the power transmission of the two transmission sprockets and transmission chains, reversing any one of the threaded propulsion shafts can synchronously reverse and drive the two threaded propulsion shafts. When the two threaded propulsion shafts are synchronously reversed and driven, the two lifting frames and the two rubber-coated conveying rollers on the upper side can be driven to slide up synchronously, and the two rubber-coated conveying rollers on the upper side can be controlled to separate from the two rubber-coated conveying rollers on the lower side at the same time. This can save the trouble of sliding the two rubber-coated conveying rollers on the upper side step by step to free up the gap for laser film threading, and the operation is simple and efficient.

[0076] Preferably, an electric control box 10 is fixedly mounted on one rack 1 .

[0077] The following is a detailed explanation of the working principles, specific details, implementation steps, functions and interrelationships of the above features, as well as their role in implementing this technical solution:

[0078] The four rubber-wrapped conveying rollers 5 can rotate synchronously in the opposite direction to roll the laser film passing through them. Under the conveyance of the four rubber-wrapped conveying rollers 5, the laser film pulls the laser film roll 4 to rotate clockwise and unwind. The laser film conveyed to the cutter 603 through the rubber-wrapped conveying rollers 5 is supported on the top horizontal part of the L-shaped supporting plate 15. When the laser film is conveyed to the top horizontal part of the L-shaped supporting plate 15, it is continuously conveyed toward the material plate 105 and passes through the film-passing space between the cutter 603 and the L-shaped supporting plate 15. When the laser film passes through the film-passing space After the length of the film space reaches the specified cutting length, the four rubber-wrapped conveying rollers stop rotating, and the continuous conveying of the laser film is stopped. At this time, the laser film that has passed through the film space and has a certain length collapses and is carried on the material receiving plate 105. At the same time as the four rubber-wrapped conveying rollers 5 stop rotating, the power unit 12 starts and drives the driving member 121 to rotate at a higher speed. When the driving member 121 is driven to rotate downward, the guide wheel 1213 contacts the horizontal force plate 601 and pushes the horizontal force plate 601, the U-shaped knife holder 6 and the cutter 603. It slides down quickly to cut the laser film that collapses and is carried on the material receiving plate 105. The power unit 12 drives the driving member 121 to rotate one circle and stops automatically after completing a cutting operation. In the above process, when the U-shaped knife holder 6 is driven to slide down, the springs on the two vertical track rods 602 are compressed by the two convex limit frames 6021. In the process of the driving member 121 being driven to rotate upward, it gradually separates from the horizontal force plate 601 and gradually releases its downward holding force acting on the two springs. In this process, the The two springs gradually and automatically push back to drive the U-shaped knife holder 6 and the cutter 603 to slide up and reset, and to clear the film-passing space again, preparing for the second conveying and cutting operation of the laser film. When the U-shaped knife holder 6 and the cutter 603 slide up and reset, the four rubber-coated conveyor rollers 5 are triggered to start and perform the second cutting operation. In this way, the automatic segmented cutting of the laser film can be achieved by automatically and intermittently alternatingly driving the four rubber-coated conveyor rollers 5 and the cutter 603. The cut laser film fragments are gradually stacked and accumulated on the top of the material receiving plate 105.

[0079] Through the power transmission of three sprockets 13, drive chains 14 and four drive gears 501, the drive assembly 11 can drive the four rubber-coated conveying rollers 5 to rotate synchronously in the opposite direction to roll-convey the laser film. The drive assembly 11 and the power unit 12 are both composed of a servo motor and a reducer. In the above process, the automatic start and stop control of the rubber-coated conveying roller 5 and the automatic start and stop control of the power unit 12 can be achieved by controlling the automatic start and stop of the servo motors of the drive assembly 11 and the power unit 12. The automatic start and stop of the two servo motors is achieved through an automatic control system.

[0080] It is worth noting that the automation control system is composed of electrical control components such as servo drives, automation controllers, and various photoelectric limit switches. The model selection of servo drives, automation controllers, and various photoelectric limit switches, the connection and wiring methods between them, and the control principles of the automation control system are existing technologies for personnel engaged in equipment automation modification, design, and testing in this field, so they will not be described in detail here; the servo drive and automation controller are arranged in the electrical control box 10.

[0081] When the head end parts of the two centering shafts 301 are plugged into the two end parts of the reel 401, the laser film reel 4 can be plugged and positioned between the two positioning sleeves 3, and the laser film reel 4 and the reel 401 can rotate around the two positioning sleeves 3 to pull and unwind the laser film on the laser film reel 4; when the two ends of the reel 401 are clamped in the two semicircular support rings 305, they are coaxially aligned with the positioning sleeves 3. At this time, the head end parts of the two centering shafts 301 can be directly plugged into the two end parts of the reel 401 to position the laser film reel 4, which can save the time of positioning the laser film reel 4 each time. , the trouble of calibrating and aligning the reel 401 and the positioning sleeve 3 is eliminated, and the operation is convenient and time-saving; rotating the horizontal drive shaft 204 forward and backward can drive the two threaded sleeves 3031, the two upright transmission rods 303 and the two centering shafts 301 to slide toward or away from each other, and control the two centering shafts 301 to be plugged into or pulled out of the reel 401, so as to lock and unlock the laser film reel 4; the horizontal drive shaft 204 can be driven by any L-shaped rocker 2041; when disassembling and replacing the laser film reel 4, the two centering shafts 301 need to be pulled out and unlocked from the reel 401.

[0082] The two sliding sleeves 3021, the two connecting rods 3042, the two U-shaped sliding frames 3041 and the two arc-shaped brake plates 304 are connected together to form two sets of crank slider mechanisms. Through the two sets of crank slider mechanisms, the two sliding sleeves 3021 sliding toward or away from each other can drive the two arc-shaped brake plates 304 to slide up and down. When the two arc-shaped brake plates 304 are driven to slide upward, they respectively come into contact with the outer periphery of the two end parts of the reel 401. When the arc-shaped brake plates 304 come into contact with the reel 401, the arc-shaped brake pads 3043 are squeezed between the arc-shaped brake plates 304 and the reel 401, and friction braking can be applied to the reel 401. This can avoid the reel 401 lacking the necessary braking deceleration, causing the four rubber-coated conveying rollers 5 to stop intermittently. The laser film roll 4 is on the laser film Under the action of the traction inertia force, it continues to rotate for multiple circles and cannot stop in time, resulting in unnecessary unwinding accumulation of the laser film between the rubber-coated conveying roller 5 and the laser film roll 4, and it cannot be kept in a tensioned state, affecting the precise conveying of the laser film by the rubber-coated conveying roller 5 in the subsequent process, and reducing the fixed-length cutting accuracy of the laser film; when the arc-shaped brake plate 304 and the arc-shaped brake pad 3043 slide down and separate from the reel 401, space can be left inside the semicircular support ring 305 for the reel 401 to be tightly clamped, avoiding the arc-shaped brake plate 304 and the arc-shaped brake pad 3043 protruding from the semicircular support ring 305, and lifting the reel 401 of the newly replaced laser film roll 4, causing the reel 401 to be unable to align with the positioning sleeve 3 when clamped in the semicircular support ring 305.

[0083] When the two vertical transmission rods 303 are pushed and driven to slide toward each other, and the two centering shafts 301 are controlled to implement plug-in positioning on the reel 401, the two sleeves 3021 can be pushed and driven to slide toward each other, and the two arc-shaped brake plates 304 can be driven to slide upward for braking. When the two sleeves 3021 are driven to slide toward each other, the springs on the two U-shaped limit frames 302 are compressed. When the two centering shafts 301 and the two vertical transmission rods 303 are driven to slide backwards, the two vertical transmission rods 303 gradually separate from the two sleeves 3021, and gradually release the compressive holding force acting on the two springs through the sleeves 3021. In this process, the two springs gradually release themselves. The dynamic reverse thrust drives the two sleeves 3021 to slide back and reset, and drives and controls the two arc-shaped brake plates 304 to slide down to the empty position. In this way, through the power transmission of the two sets of crank slider mechanisms and in conjunction with the reverse thrust effect of the springs on the two U-shaped limit frames 302, the plug-in locking and withdrawal unlocking operations of the two centering shafts 301 and the upward braking and downward sliding operations of the two arc-shaped brake plates 304 can be driven and executed at one time by the shared horizontal drive shaft 204. This can save the trouble of manually performing the above two operations step by step before and after disassembling and replacing the laser film roll 4, help simplify the disassembly and replacement steps of the laser film roll 4, and indirectly improve the operational efficiency of the production equipment.

[0084] The two vertical transmission rods 303 and the two centering shafts 301 are driven to slide toward each other. When the laser film roll 4 is inserted and positioned, the two vertical transmission rods 303 can slide through the distance between the vertical transmission rods 303 and the sliding sleeve 3021 in the initial state (refer to Figure 9 ) The time required is for the centering shaft 301 to be plugged and matched with the reel 401 in advance, so that the centering shaft 301 is plugged and matched with the reel 401 first, and the vertical transmission rod 303 is only in contact with the sliding sleeve 3021, to avoid that the vertical transmission rod 303 is in contact with the sliding sleeve 3021 and pushes to drive the arc brake plate 304 to slide upwards before the centering shaft 301 is plugged and matched with the reel 401, and the reel 401 that has not been plugged and positioned by the centering shaft 301 is protruded and lifted, causing the positioning sleeve 3 and the reel 401 to be misaligned, resulting in the centering shaft 301 being unable to be aligned and plugged with the reel 401 in the subsequent process. This helps to ensure the normal and effective implementation of the one-time driving function of the centering shaft 301 and the arc brake plate 304.

[0085] When threading the laser film between the four rubber-coated conveying rollers 5, the two upper rubber-coated conveying rollers 5 need to be slid up and separated from the two lower rubber-coated conveying rollers 5 to leave a gap between the four rubber-coated conveying rollers 5 for threading the laser film. Through the power transmission of the two transmission sprockets 701 and the transmission chain 702, reversing any one of the threaded propulsion shafts 7 can synchronously reverse and drive the two threaded propulsion shafts 7. When the two threaded propulsion shafts 7 are synchronously reversed and driven, the two lifting frames 8 and the two upper rubber-coated conveying rollers 5 can be driven to slide up synchronously, and the two upper rubber-coated conveying rollers 5 are controlled to separate from the two lower rubber-coated conveying rollers 5 at the same time. This can save the trouble of sliding the two upper rubber-coated conveying rollers 5 step by step to leave a gap for threading the laser film, and the operation is simple and efficient.
