Description

Technical Field

[0001] This invention relates to the field of plastic film recycling equipment technology, specifically to a film roll recycling machine unloading assembly and its unloading monitoring and alarm device. Background Technology

[0002] In existing technologies, unloading of film rolls mostly relies on manual labor, which is labor-intensive, inefficient, and easily damages the film. The film unloading assembly aims to realize automatic unloading of film rolls and replacement of the core, while the unloading monitoring and alarm device is used to monitor the unloading status in real time and alarm for abnormalities. The two complement each other and work together to improve the automation level and operational stability of film roll recycling.

[0003] Currently, most mainstream automatic film winding machines on the market use a single rotatable roller. The roller achieves winding by rotating. When the film roll reaches the preset thickness, there are two unloading methods: one is to directly replace the new roller, and the other is to push the film off the roller and then reassemble the roller. Regardless of which method is used, the film winding process will be interrupted, affecting the overall progress.

[0004] To address this issue, a new type of recycling machine has been developed in the existing technology. Its core design is to replace the traditional integrated roller with a multi-piece modular structure. One end of the modular roller can achieve synchronous gathering. After the film roll is wound, the gathering end of the plate will shrink inward, making the entire roller form a cone shape that is wide at one end and narrow at the other. Then the roller as a whole tilts downward towards the gathering end, and the film material slides down and is unloaded by its own gravity.

[0005] The drawback is that during the assembly of the panels, the panels are very prone to getting stuck or clamped on the membrane. On the one hand, the jamming will hinder the smooth sliding of the membrane material. On the other hand, if the membrane material is clamped by the panels, the clamped part will be subjected to strong tensile force during the sliding process, which will cause the membrane material to break, destroy the overall integrity of the membrane material, and affect subsequent use. Summary of the Invention

[0006] The purpose of this invention is to provide a film unloading assembly for a film roll recycling machine to solve the problems mentioned in the background art.

[0007] Another objective of this invention is to provide a material unloading monitoring and alarm device.

[0008] To solve the above-mentioned technical problems, the present invention provides a film unloading assembly for a film recycling machine, including a connecting seat and a movable rod vertically disposed at the center of the connecting seat. The movable rod can reciprocate in a direction perpendicular to the connecting seat via a driving component. Hinges are respectively disposed at both ends of the movable rod, and multiple take-up roller housings are arranged at equal intervals around the outer periphery of the movable rod to form a complete winding roller. The two sides of the take-up roller housing are respectively hinged to two hinge seats, so that when the two hinge seats move in the same direction, the multiple take-up roller housings tilt to one side, forming a conical shape as a whole; it also includes…

[0009] A support rod is sleeved on the outer periphery of the movable rod and connected to the end face of the connecting seat. The outer periphery of the support rod is provided with at least one strip-shaped slide extending along its length, and a push block is slidably arranged in the strip-shaped slide.

[0010] Triggers, including at least,

[0011] The deformable part is provided in the strip slide and is connected to the bottom of the push block to provide the rebound force for the push block to reset in the strip slide.

[0012] The extrusion section is located on the moving rod. When the driving component drives the moving rod to move, the extrusion section on the moving rod extrudes and deforms the deformation section until the two separate. The push block rebounds under the action of the deformation section and pushes the film roll away from the unloading assembly.

[0013] Furthermore, the outer periphery of the support rod is provided with multiple strip-shaped slides at equal intervals. Each strip-shaped slide and the line connecting its two adjacent take-up roller shells form an isosceles triangle or an equilateral triangle. The hinge seat is slidably connected within the strip-shaped slide.

[0014] Furthermore, in the initial state, the radial length of the push block along the connecting seat is less than or equal to the radius of the circumference of the winding roller housing.

[0015] Furthermore, the two ends of the deformable part are respectively connected to the two ends of the strip slide. Multiple mounting plates are provided between the push block and the strip slide. The multiple mounting plates are arranged at equal intervals along the axial direction of the support rod. One end of the mounting plate is connected to the push block, and the other end passes through the strip slide and is connected to the deformable part.

[0016] The extrusion section is configured in multiple ways, with the number of extrusion sections equal to the number of deformation sections. The multiple extrusion sections are arranged at equal intervals along the circumference of the moving rod. Each extrusion section corresponds to one of the deformation sections and protrudes from the outer peripheral wall of the moving rod to push the deformation section.

[0017] Furthermore, the deformable part consists of multiple spring rings connected end to end, the spacing between the multiple spring rings is equal to the distance between adjacent mounting plates, each spring ring is connected to one of the mounting plates, and the spring rings located at the beginning and end of the deformable part are respectively connected to the inner walls of both sides of the strip slide.

[0018] Furthermore, the extrusion part also includes a pressure plate, one end of which is connected to the outer wall of the moving rod, and the other end is inclined in the direction away from the moving rod and connected to a connecting plate. A backing plate is provided on the side of the pressure plate opposite to the deformation part. Both ends of the backing plate are connected to the outer wall of the moving rod. The middle of the backing plate is arched in the direction away from the moving rod, and the height of the arch is greater than the distance between the end of the pressure plate away from the moving rod and the moving rod.

[0019] The end of the connecting plate away from the pressure plate is connected to the highest point of the inner arc wall of the abutment plate. There is a gap between the connecting plate and the moving rod. The side of the abutment plate corresponding to the deformed part forms a contact surface. Both the pressure plate and the abutment plate are elastic.

[0020] Furthermore, a through groove is provided on one side of the abutment corresponding to the pressure plate, and the connecting plate is inserted into the through groove, and the connecting plate can slide along the through groove.

[0021] Furthermore, the support rod is provided with two sets of strip grooves, which are spaced apart and correspond to the two ends of the take-up roller housing respectively. Each strip groove corresponds to one of the take-up roller housings. The hinge seat includes a slider that is slidably connected in the strip groove. One end of the slider is hinged to the take-up roller housing and the other end is connected to the moving rod. When the moving rod moves axially, it drives the slider to move so that one end of the take-up roller housing moves closer to or away from the support rod.

[0022] Furthermore, the hinge seat also includes a fixing block connected to the outer wall of the slider. Connecting rods are provided on both sides of the fixing block, and a rotating rod is connected between the two connecting rods. The outer wall of the fixing block and the rotating rod are rotatably connected.

[0023] The ends of the two connecting rods away from the fixed block are provided with mounting rods. The side of the take-up roller housing corresponding to the support rod is provided with a fixing rod. The inner arc wall of the take-up roller housing corresponding to the support rod is connected to the outer wall of the fixing rod. Both ends of the fixing rod protrude from both ends of the take-up roller housing. One end of the fixing rod and the end of the connecting rod away from the fixed block are rotatably connected to the mounting rod through a rotating shaft.

[0024] A material unloading monitoring and alarm device, applied to the film unloading assembly of any of the above-described roll film recycling machines, comprising:

[0025] Warning bars are installed at both ends of the take-up roller housing. One end of the warning bar is connected to the outer wall of the rotating shaft. The warning bar abuts against the end of the take-up roller housing and extends outward. A trigger-type alarm device is installed at the end of the warning bar away from the take-up roller housing to monitor the winding thickness of the film on the take-up roller.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. In this invention, after the film winding reaches the standard, the driving component drives the moving rod to move, so that one end of the take-up roller housing is gathered and the other end is expanded to form a slope. At this time, the push block protrudes, and the moving rod drives the extrusion part to abut against the deformation part, so that after deformation, it resets by elastic potential energy, and drives the push block to move back and forth to help push away the wound film.

[0028] 2. In this invention, each spring ring of the deformation part corresponds to a fixed set of mounting plates. When the extrusion part pushes the spring ring, the force can be quickly transmitted to the mounting plate, driving the push block to move. After the spring ring is pushed and contracts, it passes over the extrusion part by means of elastic potential energy. The push block moves back. As the moving rod continues to move, the extrusion part repeatedly abuts against the subsequent spring ring, repeating the push block movement and return movement, so that the push block continuously pushes the film.

[0047] 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.

[0048] This invention provides a technical solution:

[0049] See Figures 1-12 As shown, it includes a connecting seat 3 and a moving rod 7 vertically positioned at the center of the connecting seat 3. The moving rod 7 can reciprocate in a direction perpendicular to the connecting seat 3 via a driving component. Hinges are respectively provided at both ends of the moving rod 7, and multiple take-up roller housings 2 are arranged at equal intervals around the outer periphery of the moving rod 7 to form a complete winding roller. The two sides of the take-up roller housing 2 are respectively hinged to two hinge seats, so that when the two hinge seats move in the same direction, the multiple take-up roller housings 2 tilt to one side, forming a cone shape as a whole; it also includes...

[0050] The support rod 6 is sleeved on the outer periphery of the movable rod 7 and connected to the end face of the connecting seat 3. The outer periphery of the support rod 6 is provided with at least one strip slide 8 extending along its length direction, and a push block 5 is slidably arranged in the strip slide 8.

[0051] Triggers, including at least,

[0052] The deformable part 53 is disposed in the strip slide 8 and is connected to the bottom of the push block 5 to provide the spring force for the push block 5 to reset in the strip slide 8.

[0053] The extrusion part 52 is provided on the moving rod 7. When the driving member drives the moving rod 7 to move, the extrusion part 52 on the moving rod 7 extrudes the deformation part 53 and gradually deforms until the two separate. The push block 5 rebounds under the action of the deformation part 53 and pushes the film roll to detach from the unloading assembly.

[0054] Multiple take-up roller housings 2 are arranged circumferentially to form a cylindrical winding roller. The connecting seat 3 is rotatably connected to the recycling machine. The recycling machine is equipped with a drive device for driving the connecting seat 3 to rotate. The drive device can be a motor. One end of the support rod 6 is fixedly connected to the connecting seat 3. Therefore, when the connecting seat 3 rotates, it will drive the support rod 6 to rotate. And when the support rod 6 rotates, it will drive the take-up roller housing 2 to rotate together. The motor has a reducer, so that the rotation speed of the connecting seat 3 is slow, so that the rotating take-up roller housing 2 will not generate centrifugal force.

[0055] The film to be recycled is wound on the winding roller, and then multiple take-up roller housings 2 rotate, so that the film is gradually wound on the winding roller, achieving the effect of recycling the film. The moving rod 7 is inserted into the support rod 6, and the moving rod 7 can move along its axial direction. One end of the moving rod 7 passes through the connecting seat 3. The recycling machine is equipped with a drive unit for driving the moving rod 7 to move, which can be a hydraulic rod or a cylinder or other equipment.

[0056] When the film winding thickness is sufficient, the motor stops driving the connecting seat 3 to rotate, and then the driving component drives the moving rod 7 to move in the direction of the connecting seat 3. At this time, please see... Figure 5 The moving rod 7 moves to the right, pulling the hinge seat at the left end of the take-up roller housing 2 to the right, causing the left end of the take-up roller housing 2 to tilt towards the support rod 6, forming a state where multiple take-up roller housings 2 are gathered at one end, while the right end of the take-up roller housing 2 tilts away from the support rod 6, and then the winding roller will form an effect of being narrow at one end and wide at the other, with a slope. At this time, the film can slide to the left along the slope of the take-up roller housing 2.

[0057] When the take-up roller housing 2 is parallel to the support rod 6, the end of the push block 5 away from the support rod 6 will not protrude from the outer surface of the take-up roller housing 2. After the left end of the take-up roller housing 2 is tilted, the push block 5 will protrude from the outer surface of the take-up roller housing 2. When the moving rod 7 moves, it will drive the extrusion part 52 to move together and abut against the deformation part 53. One end of the deformation part 53 will deform. The part of the deformation part 53 that contacts the extrusion part 52 will move towards the deformed end of the deformation part 53. During the movement, the push block 5 will move.

[0058] When the deformable end of the deformable part 53 deforms, it stores elastic potential energy and springs back to its original position. Then, the part of the deformable part 53 that contacts the extrusion part 52 will pass over the extrusion part 52 due to this force, causing the push block 5 to move back. The direction of the push block 5's movement is the end where the multiple take-up roller housings 2 are gathered together. When the push block 5 moves, it generates a pushing force on the film, helping the film to fall off the winding roller. At the same time, the push block 5 also has a certain effect of pushing the film outward, preventing the film from being trapped in the gap between the multiple take-up roller housings 2 when one end is gathered together.

[0059] After the take-up roller housing 2 is gathered at one end, the recovery machine controls the entire take-up and unloading roller body 1 to tilt, that is, to make the gathered end of the multiple take-up roller housings 2 face downward, so that the film slides off due to gravity.

[0060] See Figures 3-7 Multiple strip tracks 8 are evenly spaced around the outer periphery of the support rod 6. Each strip track 8 forms an isosceles triangle or an equilateral triangle with the line connecting its two adjacent take-up roller housings 2. The hinge seat is slidably connected within the strip track 8.

[0061] Push block 5 extends through strip slide 8 to the gap between multiple take-up roller housings 2. After the moving rod 7 triggers the push block 5 to move, push block 5 can move within the length range of strip slide 8, combined with... Figure 3 and Figure 4 As can be seen, the strip slide 8 and the push block 5 are the same in three sets. The strip slide 8 is opened on the support rod 6. Each set of strip slide 8 and push block 5 has four, which corresponds to the four gaps between the four take-up roller housings 2. In this way, the push block 5 can push the film through the gaps when it moves.

[0062] See Figures 1-12 In the initial state, the radial length of the push block 5 along the connecting seat 3 is less than or equal to the radius of the circumference at the take-up roller housing 2.

[0063] Because the pusher 5 will only protrude from the end of the take-up roll housing 2 when the housing is tilted, and the take-up roll housing 2 is in a tilted state, therefore... Figure 3 The three sets of push blocks 5 arranged from left to right have different radial lengths, and are arranged in a stepped manner from short to long from left to right. This ensures that when the take-up roller housing 2 is tilted, all three sets of moving push blocks 5 can push the film.

[0064] See Figures 2-12 The two ends of the deformable part 53 are fixedly connected to the two ends of the strip slide 8 respectively. Multiple mounting plates 51 are provided between the push block 5 and the strip slide 8. The multiple mounting plates 51 are arranged at equal intervals along the axial direction of the support rod 6. One end of the mounting plate 51 is fixedly connected to the push block 5, and the other end passes through the strip slide 8 and is fixedly connected to the deformable part 53.

[0065] Multiple extrusion sections 52 are provided, and their number is equal to the number of deformation sections 53. The multiple extrusion sections 52 are arranged at equal intervals along the circumference of the moving rod 7. Each extrusion section 52 corresponds to one of the deformation sections 53 and protrudes from the outer peripheral wall of the moving rod 7 to push the deformation section 53.

[0066] There are three sets of push blocks 5 and strip slides 8, with four push blocks 5 and four strip slides 8 in each set. There are four gaps between the four take-up roller housings 2. Therefore, each push block 5 and strip slide corresponds to a specific gap. The multiple mounting plates 51 fixed on each push block 5 will not exceed the length of the push block 5. Please see... Figure 12 The length of the strip slide 8 is longer than the arrangement length of the mounting plates 51, providing space for the sliding of the push block 5 and the mounting plates 51;

[0067] The deformable part 53 connects multiple mounting plates 51 in series. When the take-up roller housing 2 is in a parallel state, the extrusion part 52 has an arc and does not contact the deformable part 53. When the moving rod 7 moves towards the connecting seat 3 and the left end of the take-up roller housing 2 gradually tilts, the extrusion part 52 moves with the moving rod 7 and abuts against the deformable part 53. When the extrusion part 52 abuts against the first spring ring of the deformable part 53, it will push the entire deformable part 53 to deform towards the connecting seat 3, and the push block 5 and the mounting plate 51 will also move together.

[0068] exist Figure 12 As can be seen, there is a gap between the two outermost mounting plates 51 and the ends of the strip slide 8. This is because the two ends of the deformable part 53 are fixedly connected to the inner walls of the two ends of the strip slide 8. Therefore, the length of the deformable part 53 is the same as the length of the strip slide 8. The length of the deformable part 53 is longer than the length of multiple mounting plates 51 arranged in a row. Since the part of the deformable part 53 that is fixedly connected to the mounting plate 51 cannot deform, when one end of the deformable part 53 is pushed, the whole part will squeeze the other end, which is the part that is not connected to the mounting plate 51.

[0069] As the extrusion section 52 continues to move, the contracted end of the deformation section 53 will exert force in the direction away from the connecting seat 3 due to the generated elastic potential energy, so that the part in contact with the extrusion section 52 slides over the arc of the extrusion section 52 and passes over the extrusion section 52. Then the deformation section 53 extends a certain distance again, so that the mounting plate 51 and the push block 5 move away from the connecting seat 3. The direction away from the connecting seat 3 is the end of the take-up roller housing 2 that is gathered. Therefore, when the push block 5 moves back, it can generate a pushing force on the film, and the direction of this pushing force is the direction in which the film is to slide out.

[0070] A sleeve 54 is slidably connected to the outer wall of the moving rod 7. The sleeve 54 has multiple inner grooves 17 corresponding to the strip slide 8. The deformable part 53 extends into the inner groove 17 on the side near the moving rod 7. The end of the mounting plate 51 away from the push block 5 is fixedly connected to the sleeve 54.

[0071] See Figure 10 The deformable part 53 consists of multiple spring rings connected end to end. The spacing between the multiple spring rings is equal to the distance between adjacent mounting plates 51. Each spring ring is fixedly connected to one of the mounting plates 51. The spring rings located at the beginning and end of the deformable part 53 are fixedly connected to the inner walls of both sides of the strip slide 8.

[0072] Each spring coil of the deformable part 53 corresponds to a mounting plate 51 in each group. In this way, when a single spring coil is pushed by the extrusion part 52, the force can be transmitted to the mounting plate 51 more quickly, thereby causing the push block 5 to move. As the extrusion part 52 moves, the contracted end of the deformable part 53 will exert force in the direction away from the connecting seat 3 due to the generated elastic potential energy, so that the spring coil in contact with the extrusion part 52 slides over the arc of the extrusion part 52 and passes over the extrusion part 52.

[0073] As the moving rod 7 continues to move, the extrusion section 52 will soon abut against the next spring coil of the deformation section 53, and then push one end of the deformation section 53 to contract again, and the mounting plate 51 and push block 5 move. Then the deformation section 53 exerts force again and passes over the extrusion section 52, causing the push block 5 to move back. Therefore, in the state where the moving rod 7 moves and causes one end of the take-up roller housing 2 to converge, the push block 5 can continuously push the film to help the film detach from the winding roller.

[0074] See Figures 4-12 The extrusion section 52 also includes a pressure plate 521. One end of the pressure plate 521 is fixedly connected to the outer wall of the moving rod 7, and the other end is inclined in the direction away from the moving rod 7 and fixedly connected to a connecting plate 522. A backing plate 523 is provided on the side of the pressure plate 521 facing away from the deformation section 53. Both ends of the backing plate 523 are fixedly connected to the outer wall of the moving rod 7. The middle part of the backing plate 523 is arched in the direction away from the moving rod 7, and the height of the arch is greater than the distance between the end of the pressure plate 521 away from the moving rod 7 and the moving rod 7.

[0075] The end of the connecting plate 522 away from the pressure plate 521 is fixedly connected to the highest point of the inner arc wall of the abutment plate 523. There is a gap between the connecting plate 522 and the moving rod 7. The abutment plate 523 forms a contact surface 524 on one side corresponding to the deformable part 53. Both the pressure plate 521 and the abutment plate 523 are elastic.

[0076] Please see Figure 11In the initial state, the extrusion part 52 is on the left side of the deformation part 53, that is, near the gathering end of the take-up roller housing 2. After the moving rod 7 starts to move to the right, the pressure plate 521 first contacts the deformation part 53. The extrusion force of the deformation part 53 causes the end of the pressure plate 521 fixed to the connecting plate 522 to tilt towards the outer wall of the moving rod 7. Then, the tilted end of the pressure plate 521 pushes the connecting plate 522 closer to the moving rod 7, and the other end of the connecting plate 522 pulls the highest point of the abutment plate 523 closer to the moving rod 7.

[0077] When the spring coil of the deformable part 53 passes the pressure plate 521, the pressure plate 521 rebounds, causing the connecting plate 522 to be lifted again and moved away from the moving rod 7. At this time, the spring coil abuts against the contact surface 524, and then the spring coil is pushed by the limit of the abutment plate 523 to move the entire deformable part 53. When the deformable part 53 is pushed and then retracted, the distance between multiple spring coils is reduced.

[0078] When one of the spring coils is in contact with the contact surface 524, the pressure plate 521 can move to the next adjacent spring coil, and then the entire adjacent spring coil will squeeze the pressure plate 521, thereby pulling the arched part of the abutment plate 523 towards the moving rod 7 through the connecting plate 522. The pressure plate 521 has a slope to facilitate sliding between the deformable part 53 and the moving rod 7. Then the outer ring wall of the deformable part 53 squeezes the pressure plate 521, causing it to be squeezed towards the moving rod 7.

[0079] After the arched protrusion of the abutment plate 523 is pulled closer to the moving rod 7, its blocking force on the spring coil is reduced, and then the spring coil that is in contact with the contact surface 524 can pass over the abutment plate 523. Both the abutment plate 523 and the pressure plate 521 have elastic recovery after deformation.

[0080] See Figure 11 A through groove 525 is provided on one side of the abutment plate 523 corresponding to the pressure plate 521, and a connecting plate 522 is inserted into the through groove 525. The connecting plate 522 can slide along the through groove 525.

[0081] The through slot 525 corresponds to the pressure plate 521. When the end of the pressure plate 521 connected to the connecting plate 522 is facing or away from the moving rod 7, the connecting plate 522 will move towards or away from the moving rod 7. During the movement, the connecting plate 522 can move within the range of the through slot 525.

[0082] See Figures 4-7 The support rod 6 has two sets of strip grooves 9. The two sets of strip grooves 9 are spaced apart and correspond to the two ends of the take-up roller housing 2 respectively. Each strip groove 9 corresponds to one of the take-up roller housings 2. The hinge seat includes a slider 10 that is slidably connected in the strip groove 9. One end of the slider 10 is hinged to the take-up roller housing 2 and the other end is fixedly connected to the moving rod 7. When the moving rod 7 moves axially, it drives the slider 10 to move so that one end of the take-up roller housing 2 is close to or away from the support rod 6.

[0083] As shown in the figure, there are four take-up roller housings 2, and in the two sets of strip grooves 9, there are also four strip grooves 9 in each set. Each strip groove 9 corresponds to one of the take-up roller housings 2. The two sets of strip grooves 9 are distributed at the left and right ends of the support rod 6, corresponding to the ends of the take-up roller housings 2. Each strip groove 9 has a slider 10 slidably connected in it. The slider 10 is fixedly connected to the moving rod 7. The end of the slider 10 away from the moving rod 7 is hinged to the end of the take-up roller housing 2.

[0084] Please see Figure 5 After the moving rod 7 moves to the right, the left end of the take-up roller housing 2 tilts toward the support rod 6. After the moving rod 7 moves to the left, it only needs to move until the left end and the right end of the take-up roller housing 2 are parallel. The right end of the take-up roller housing 2 does not need to tilt excessively toward the support rod 6.

[0085] See Figures 4-6 The hinge seat also includes a fixing block 11 fixedly connected to the outer wall of the slider 10. Connecting rods 13 are provided on both sides of the fixing block 11. A rotating rod 12 is fixedly connected between the two connecting rods 13. The outer wall of the fixing block 11 and the rotating rod 12 are rotatably connected. An installation rod 15 is provided at the end of the two connecting rods 13 away from the fixing block 11. A fixing rod 16 is provided on the side of the take-up roller housing 2 corresponding to the support rod 6. The inner arc wall of the take-up roller housing 2 corresponding to the support rod 6 is fixedly connected to the outer wall of the fixing rod 16. Both ends of the fixing rod 16 protrude from both ends of the take-up roller housing 2. One end of the fixing rod 16 and the end of the connecting rod 13 away from the fixing block 11 are rotatably connected to the installation rod 15 through a rotating shaft 14.

[0086] Please combine Figure 5 and Figure 6 First, the connecting rod 13 on the right is longer than the connecting rod 13 on the left. After the moving rod 7 moves to the right to its apex, the end of the connecting rod 13 on the right that is away from the take-up roller housing 2 is still tilted to the left, while the connecting rod 13 on the left is close to parallel. When the take-up roller housing 2 is parallel, the end of the connecting rod 13 on the left that is away from the take-up roller housing 2 will only tilt slightly towards the connecting seat 3, while the end of the connecting rod 13 on the right that is away from the take-up roller housing 2 will tilt to the left at an excessive angle and be close to parallel.

[0087] When the moving rod 7 moves to the right, the left end of the take-up roller housing 2 will gradually move to the right and approach the support rod 6 as the end of the connecting rod 13 away from the take-up roller housing 2 moves to the right. When the end of the connecting rod 13 on the right side away from the take-up roller housing 2 moves to the right, it changes from a nearly parallel state to a nearly vertical state. Therefore, the right end of the take-up roller housing 2 will expand outward.

[0088] Then look Figure 6When the moving rod 7 moves, it drives the slider 10 to slide along the strip groove 9. When the slider 10 moves, it drives the connecting rod 13 through the fixed block 11. The rotating rod 12 can rotate within the fixed block 11 to adapt to the change in the angle of the connecting rod 13. The rotating shaft 14 will also rotate with the change in the angle of the connecting rod 13. Then the connecting rod 13 can push the fixed rod 16 to tilt the take-up roller housing 2.

[0089] When the connecting seat 3 rotates, it drives the support rod 6 to rotate. The slider 10 is slidably engaged with the strip groove 9. When the support rod 6 rotates, it will drive the slider 10 to rotate together, thereby driving the entire hinge seat to rotate, and through the hinge seat, it will drive the take-up roller housing 2 to rotate together.

[0090] See Figures 1-12 The present invention also provides a material unloading monitoring and alarm device, applied to a film unloading assembly of a film rewinding machine in any of the above embodiments, comprising,

[0091] Warning rods 4 are set at both ends of the take-up roller housing 2. One end of the warning rod 4 is fixedly connected to the outer wall of the rotating shaft 14. The warning rod 4 abuts against the end of the take-up roller housing 2 and extends outward. A trigger-type alarm device is installed at the end of the warning rod 4 away from the take-up roller housing 2 to monitor the winding thickness of the film on the winding roller.

[0092] The warning rods 4 at both ends of the take-up roller housing 2 can serve as a barrier to prevent the film being wound on the winding roller from falling off. As the thickness of the film increases, when the thickness of the film reaches the trigger alarm device on the warning rod 4, the trigger alarm device will sound an alarm and send an electrical signal to the recycling machine. Then the recycling machine controls the motor to stop driving the connecting seat 3 to rotate, and then the recycling machine controls the drive component to drive the moving rod 7 to start moving.

[0093] After the left end of the take-up roller housing 2 is gathered, the warning bar 4 located at the left end of the take-up roller housing 2 will tilt as the angle of the mounting rod 15 changes. Therefore, after the left end of the take-up roller housing 2 is gathered, the warning bar 4 located at the left end of the take-up roller housing 2 will tilt in the same direction as the tilt angle of the take-up roller housing 2, and the film can slide out along the slope of the take-up roller housing 2 and the warning bar 4.

[0094] When the trigger-type alarm device on the left warning lever 4 detects that the film has detached, it sends an electrical signal to the recovery machine again. Then, the moving lever 7 moves to the left back to its initial state, making the take-up roller housing 2 parallel. The left warning lever 4 then returns to its initial state. Figure 1 The state shown in the image is then activated by the recycling machine's control motor, which rotates the winding roller again to rewind the film.
