Description

A rounded corner cutting system for medical films Technical Field

[0001] This invention belongs to the field of film processing technology, and specifically relates to a rounded corner cutting system for medical films. Background Technology

[0002] Medical film is a type of silver halide photosensitive material. It is mainly divided into standard sensitivity general-purpose (RX type) film, suitable for most general photography applications. It offers moderate performance, low fogging, and high contrast, enhancing the contrast between bones, air, and contrast agents. Medical film is relatively hard. To improve safety during use, it often requires rounding the corners. To enhance ease of use, notches are often cut at the edges to identify the front and back of the film. Traditionally, rounding and notching are performed separately, resulting in low efficiency, high operator workload, and a lack of systematic coordination between the notching and rounding tools. Operators are prone to errors due to fatigue, leading to missed or excessive notches, severely impacting processing quality. Summary of the Invention

[0003] In order to solve the above-mentioned problems in the prior art, the present invention aims to provide a rounded corner cutting system for medical films.

[0004] The technical solution adopted in this invention is as follows:

[0005] A rounded corner cutting system for medical films includes a worktable; a carrier plate, detachably mounted on one side of the worktable, rectangular in shape with a notch at one corner; the carrier plate is located at a corner of the worktable, with the diagonals of the worktable and the carrier plate coinciding, but their center points not coinciding, and sufficient space is left at the corner of the worktable away from the carrier plate for mounting a tool holder; a support frame, located on one side of the notch in the carrier plate, is fixedly connected to the worktable; the support frame is "door" shaped, and its interior is used to mount the main drive components and cutting tools of the system. A back panel can be installed on its back side to protect the main components of the system from dust and other contaminants. A transparent panel can be installed on its front side, hinged to the load-bearing frame, allowing it to be opened and closed to provide safety protection for workers without affecting normal operation. A rounded corner cutter is detachably mounted on the load-bearing frame. A cylinder has its cylinder barrel fixedly connected to the load-bearing frame, and its piston rod connected to the rounded corner cutter. A notched cutter holder is located on one side of the rounded corner cutter, parallel to one side of the material carrier plate. The notched cutter is detachably mounted on the notched cutter holder. The rounded corner cutter and the notched cutter work together to round the corners of the film and simultaneously cut a notch on one side of the film to easily distinguish the front and back sides. During the cutting process, the cutter is perpendicular to the film, allowing for batch processing with high cutting precision. The cutting system is simple to operate; simply align the film correctly and start the cylinder to complete the cutting task.

[0006] As a preferred embodiment of the present invention, a mounting groove is fixedly provided on the worktable, the mounting groove being located on one side of the notch in the material carrier plate. A control disk is rotatably mounted inside the mounting groove, and a shaft is located on the lower side of the control disk, the shaft being located inside the mounting groove. The control disk is located inside the load-bearing frame, which means that the maximum diameter of the weighing pan is smaller than the internal space of the load-bearing frame, i.e., the weighing pan can rotate inside the load-bearing frame. The control disk is adapted to the notch in the material carrier plate, and a rounded corner knife groove and a recessed knife groove are fixedly provided on the control disk. The function of the knife groove is to align the knife. After the knife falls, the knife is allowed to have an error in the vertical direction. The knife groove has a certain depth. As long as the knife falls to the lowest point, the knife falls into the knife groove but does not pass through the knife groove. That is, the knife is properly installed, which can ensure that the knife can completely penetrate the film without damaging the worktable.

[0007] In a preferred embodiment of the present invention, a fixed plate is fixedly installed inside the load-bearing frame, a slide rail is fixedly installed on one side of the fixed plate, a slider is slidably mounted on the slide rail, and the slider is fixedly connected to the piston rod of the cylinder; an adjusting plate is detachably installed on one side of the slider, a limiting rod is fixedly installed on the slider, the limiting rod is slidably connected to the adjusting plate, a horizontal adjustment knob is provided on the side of the adjusting plate away from the limiting rod, the horizontal adjustment knob is fixedly mounted on a horizontal adjustment screw, the horizontal adjustment screw is threadedly connected to the adjusting plate, the horizontal adjustment screw passes through the adjusting plate, and the horizontal adjustment screw is rotatably connected to the slider. Through the horizontal adjustment screw, the slider can move with the adjusting plate; conversely, if the horizontal adjustment screw is not rotated, the adjusting plate will always move with the slider; a rounded corner cutter is slidably connected to the adjusting plate, the rounded corner cutter is fixedly mounted on the adjusting block, a longitudinal adjustment screw is provided at one end of the adjusting block, the longitudinal adjustment screw is threadedly connected to the adjusting block, the end of the longitudinal adjustment screw away from the adjusting block is rotatably connected to the adjusting plate, and a longitudinal adjustment knob is fixedly mounted on the longitudinal adjustment screw. The horizontal adjustment screw, used with rounded corner cutters of different specifications, allows for flexible adjustment of the rounded corner size. The vertical adjustment screw can adjust the vertical position of the cutter. The vertical position of the cutter needs to be adjusted daily to ensure that the cutter is installed in a reasonable position.

[0008] In a preferred embodiment of the present invention, a groove is fixedly provided on the fixed plate, a connecting rod is fixedly provided on one side of the slider, and a transmission rack is fixedly provided at the end of the connecting rod away from the slider. The connecting rod is located within the groove. One side of the transmission rack has teeth, but the toothed portion is small. A worm gear is rotatably provided on the side of the fixed plate near the transmission rack. A transmission gear is fixedly provided on the worm gear, and a worm wheel is provided on one side of the worm gear. The worm wheel meshes with the worm gear and is fixedly mounted on a rotating shaft. A drive gear is fixedly provided on the rotating shaft, which is rotatably connected to the worktable. The control disk has teeth on its periphery, and the drive gear meshes with the toothed portion of the control disk. The toothed portion of the control disk is only partially toothed, and the control disk is not circular; the diameters of the toothed and toothless portions are different. The toothed portion of the control disk meshes with the drive gear, causing the control disk to rotate. The rotation angle is only ninety degrees, and the control disk rotates back and forth in both directions, thus eliminating the need for a complete gear.

[0009] As a preferred embodiment of the present invention, a baffle is provided on each side of the material carrier plate near its notch, and the baffle is fixedly connected to the worktable. One of the baffles is fixedly provided with an alignment groove, which coincides with the vertical projection of the notch tool holder. When the notch tool falls, it falls into the notch tool groove through the alignment groove. A chip collection groove is fixedly provided on the worktable, and the chip collection groove coincides with the notch of the material carrier plate. A chip discharge port is fixedly provided on the control panel, and the chip discharge port is located on one side of the notch tool groove. The shape of the chip discharge port is the same as that of the chip collection groove. A support leg is fixedly provided on the side of the worktable away from the material carrier plate, and a collection box is placed on the side of the chip collection groove away from the material carrier plate. By moving the slider up and down, the control panel is rotated forward and backward. The chips cut from the film fall into the collection box through the chip discharge port and the chip collection groove. During the processing, there is no need to clean the worktable frequently, and the chips do not affect the processing efficiency at all.

[0010] As a preferred embodiment of the present invention, a gas spring is provided on one side of the fixing plate. The gas spring includes a cylinder and a rod. The cylinder is fixedly connected to the fixing plate. A mounting block is fixedly provided at the end of the rod away from the cylinder. A beveled plate is fixedly provided on the side of the mounting block near the rounded corner cutter. The angle between the beveled plate and the mounting block is 135°, which ensures that the notch cutter holder is always parallel to the side edge of the film and that the projection point of the notch cutter's axis falls exactly on the side edge line of the film. A dovetail strip is fixedly provided on one side of the notch cutter holder. The dovetail strip is slidably connected to the beveled plate. A fastening bolt is provided at the end of the beveled plate away from the notch cutter holder. The fastening bolt is threadedly connected to the beveled plate. Multiple longitudinal adjustment bolts are provided on one side of the notch cutter holder. The longitudinal adjustment bolts are threadedly connected to the notch cutter holder. The fastening bolts directly control the position of the notch cutter holder, and the longitudinal adjustment bolts can adjust or replace the vertical position or size of the notch cutter to meet the processing of films of different sizes.

[0011] As a preferred embodiment of the present invention, a mounting groove is fixedly provided on one side of the slider, an installation shaft is provided on the adjusting plate, a spherical buckle is fixedly provided at the end of the installation shaft away from the slider, the installation shaft passes through the adjusting plate and the slider, and the end of the installation shaft away from the spherical buckle is located in the mounting groove; a control rack is fixedly provided on the side of the slide rail near the mounting groove, a control gear is meshed on one side of the control rack, the control gear is detachably mounted on the control shaft, and the control gear is connected to the control shaft through a one-way bearing; a mounting hole is fixedly provided on the slider, the mounting hole is located on one side of the mounting groove, and the control shaft is rotatably disposed in the mounting hole; the installation shaft and the control shaft are connected by a transmission assembly. By utilizing the interlocking action of the spherical buckle and the spring tongue, the workload of the notching knife is reduced, eliminating the need to cut notches at all four corners of the film. This not only facilitates the identification of the front and back of the film but also extends the service life of the notching knife. Furthermore, there is no need to control the rounding knife and the notching knife separately; a single cylinder is sufficient. By simply following the normal rounding processing steps, the additional task of cutting and identifying the notch on one side can be completed. This eliminates cumbersome operations and greatly improves the efficiency of film cutting and processing.

[0012] In a preferred embodiment of the present invention, the transmission assembly includes a notched disc and a grooved wheel. The notched disc is fixedly mounted on the control shaft. A stop plate is provided on one side of the notched disc, and the stop plate is fixedly connected to the notched disc. A transmission pin is fixedly mounted on the stop plate. A grooved wheel is provided on one side of the notched disc, and the grooved wheel cooperates with the transmission pin. The grooved wheel is fixedly mounted on a rotating shaft and is located within the mounting groove. One end of the rotating shaft is rotatably connected to the inner wall of one side of the mounting groove, and the other end of the rotating shaft is fixedly connected to the mounting shaft. An intermittent grooved wheel mechanism is used here, employing four grooved wheels to accommodate the four postures of the spherical buckle, perfectly fitting rectangular film shapes. The rounded corner cutter operates four times consecutively, with only one of those cycles driving the notched cutter.

[0013] Preferably, the inclined plate has a through groove fixedly provided on the side near the adjusting plate, and the cross-section of the through groove is rectangular. The rectangular through groove ensures that the spherical buckle can pass smoothly in the separated state. A spring tongue is provided in the through groove, and a placement space is fixedly provided on the inner wall of the through groove away from the adjusting plate. A spring is provided in the placement space, one end of the spring is fixedly connected to the inclined plate, and the other end of the spring is fixedly connected to the spring tongue. The spring tongue is slidably connected to the inclined plate, and the sliding direction of the spring tongue relative to the inclined plate is parallel to the axis of the mounting shaft. The spring tongue cooperates with the spherical buckle. When the flat surface of the spherical buckle contacts the spring tongue, it will drive the spring tongue to move together. When the arc-shaped surface of the spherical buckle contacts the spring tongue, it will squeeze the spring tongue, thereby causing the rounded corner cutter to move without driving the notch cutter to move.

[0014] As a preferred embodiment of the present invention, the spherical buckle has three surfaces: the first surface is connected to the mounting shaft, the second surface is arc-shaped, and the third surface is perpendicular to the plane where the adjusting plate is located; the projection of the spherical buckle onto the plane where the adjusting plate is located is a minor arc shape. The minor arc shape is a small circumference of a full circle, and the rotation center of the spherical buckle is the center of the circle containing the minor arc shape, so that when the spherical surface of the buckle faces left or right, it can avoid the spring tongue and pass directly through both sides of the spring tongue.

[0015] The beneficial effects of this invention are as follows: As a rounded corner cutting system for medical films, this invention utilizes a cylinder to drive a rounded corner cutter to sequentially cut the four corners of the medical film, facilitating its use; and a notched cutter is used to create a notch on one side of one corner, making it easy to distinguish the front and back of the medical film; in the specific cutting process, this invention uses a cylinder to intermittently engage the rounded corner cutter and the notched cutter, reducing the number of operations and intensity of the notched cutter while meeting usage requirements, based on the normal rounded corner cutting intensity of medical films. The operator does not need to perform additional operations to cut the notch, which effectively extends the service life of the equipment and also improves processing efficiency.

[0041] Advantageously, the spherical buckle 54 has three surfaces: the first surface is connected to the mounting shaft 53, the second surface is arc-shaped, and the third surface is perpendicular to the plane where the adjusting plate 50 is located; the projection of the spherical buckle 54 onto the plane where the adjusting plate 50 is located is a minor arc shape.

[0042] Working principle of this invention:

[0043] The neatly stacked film sheets are placed on the carrier plate 14 and pushed through the inside of the pick-and-place slot 27 until both sides of the film sheets contact the baffle 12.

[0044] When cylinder 16 is activated, it controls slider 51 to slide along slide rail 32. When slider 51 slides downward, it drives adjustment plate 50 and rounded corner cutter 44 to move synchronously, cutting off the innermost corner of the film to form a rounded corner. When slider 51 slides upward, rounded corner cutter 44 leaves the film.

[0045] During this process, the connecting rod 36 and the transmission rack 22 move together with the slider 51. The transmission rack 22 matches the transmission gear 17, and the transmission rack 22 drives the transmission gear 17. The transmission gear 17 drives the worm 18, the worm 18 drives the worm wheel 20, and the worm wheel 20 drives the rotating shaft 19 and the drive gear 21 to rotate. The drive gear 21 drives the control disk 23. The slider 51 slides up and down, causing the control disk 23 to rotate in both directions. The transmission rack 22 only has teeth on some parts. By designing the transmission ratio, the rotation angle of the control disk 23 is only ninety degrees. When the toothless part of the transmission rack 22 is close to the transmission gear 17, no transmission occurs. Furthermore, the worm wheel 20 and the worm 18 cooperate so that when the transmission rack 22 and the transmission gear 17 are not transmitting, the transmission gear 17 cannot be forced to rotate, thus giving the control disk 23 a stable posture.

[0046] Before the rounded corner blade 44 falls, the rounded corner blade groove 33 is already aligned with the rounded corner blade 44. Before the rounded corner blade 44 rises to its maximum height, the chip discharge port 35 and the chip collection groove 26 have already overlapped. The rounded corner blade 44 moves up and down, cutting the film when it falls, and the film is intercepted by the baffle 12 when it rises, and is forced to fall into the collection box.

[0047] When the notched cutter 57 and the rounded corner cutter 44 are used together: for every four drops of the rounded corner cutter 44, the notched cutter 57 drops once;

[0048] When slider 51 rises, the transmission assembly moves with slider 51. Control gear 59 and control rack 66 cooperate, control gear 59 rotates, driving control shaft 60 to rotate; when slider 51 falls, control gear 59 rotates under the action of one-way bearing, but does not drive control shaft 60 to rotate.

[0049] The notched plate 61 and the baffle plate 65 rotate together with the control shaft 60. Each rotation drives the grooved wheel 62 to rotate 90 degrees rapidly.

[0050] The rotation of the grooved wheel 62 drives the rotation shaft 63 to rotate. The mounting shaft 53 and the spherical buckle 54 rotate together with the grooved wheel 62. The spherical buckle 54 has four states: the arc surface is facing up, facing left, facing right, and facing down. When the arc surface is facing up (as shown in Figure 9), the spherical buckle 54 falls down with the slider 51. After the spherical buckle 54 contacts the spring tongue 56, the spring tongue 56, the inclined plate 41, the mounting block 38, the notched knife holder 42, and the notched knife 57 move together with the slider 51 (at this time, the ends of the notched knife 57 and the rounded corner knife 44 are flush).

[0051] The notch cutter 57 falls and aligns with the notch cutter groove 34, cutting a semi-circular notch on one side of one corner of the film to distinguish the front and back of the film;

[0052] When the slider 51 rises, the spring tongue 56 loses the constraint of the spherical buckle 54, and the inclined plate 41, mounting block 38, notched knife holder 42, and notched knife 57 are reset under the action of the gas spring and return to the maximum height.

[0053] When the curved surface of the spherical buckle 54 falls to the left or right, the slider 51 falls, and the spherical buckle 54 passes through the through groove 55 from the left or right side of the spring tongue 56 without moving the notch knife 57. At this time, the rounded corner knife 44 moves, and the notch knife 57 does not move.

[0054] When the curved surface of the spherical buckle 54 faces downward and falls, the spherical buckle 54 presses against the spring tongue 56, compressing the spring in the placement space. The spring tongue 56 and the inclined plate 41 slide together, and the spring tongue 56 retracts into the inclined plate 41. The spherical buckle 54 falls smoothly through the through groove 55. At this time, the rounded corner cutter 44 moves, while the notched cutter 57 remains stationary. The slider 51 will not move to the underside of the mounting block 38. (On the movement path of the control gear 59, the control rack 66 is not fully covered. Only when the slider 51 moves on the upper side of the inclined plate 41 will the control gear 59 and the control rack be driven. The spring tongue 56 has a long longitudinal length. After the spherical buckle 54 presses against the spring tongue 66, the spring tongue 66 is always compressed before the slider 51 rises above the inclined plate 41.) When the slider 51 rises, the posture of the spherical buckle 54 will not change immediately. The spherical buckle 54 can pass smoothly through the through groove 55, and the slider 51 returns to its maximum height.

[0055] Repeat the above process, with each film being cut four times to create four rounded corners and one identification notch.

[0056] In addition, the flexible removal of the spherical buckle 54 or the transmission component can meet the needs of film processing rounded corners without cutting notches, that is, film processing without distinguishing between the front and back or special purposes.
