Abstract
Description
Technical Field
[0001] The invention belongs to the field of medical imaging, and mainly relates to a production device for a filter plate used in an X-ray machine and a gastrointestinal machine. Background Art
[0002] In X-ray photography, due to the Compton effect, the original emission rays emitted from the X-ray tube will produce scattered rays with longer wavelengths than the original emission rays after entering the human tissue, such as Figure 1 As shown, the scattered rays radiate in random directions. The thicker the examined part is, the more scattered rays are produced. When the scattered rays act on the X-ray film, background gray fog is formed on the film, causing the resolution, clarity, and contrast of the film image to be significantly reduced.
[0003] The filter plate is placed between the human body and the film. The more filter grids the filter plate has, the more scattered rays are filtered. The most commonly used filter grids are convergent grids, that is, each lead film is inclined toward the focus, and the extended lines of the lead films are concentrated at the focus.
[0004] At present, my country's filter plates are mainly imported. Due to technical barriers, the filter grids of domestically produced filter plates are sparse, resulting in low resolution and clarity of film images, which cannot correctly reflect the specific conditions of the lesions and may cause misdiagnosis.

[0049] The present invention can be explained in more detail by the following examples. The purpose of disclosing the present invention is to protect all changes and improvements within the scope of the present invention. The present invention is not limited to the following examples.
[0050] Combined with Figure 2 , 3, 4, 10 and 11, a production device for filter plates for X-ray machines, comprising a workbench 1, the workbench 1 comprising legs 103, a table top 101 on the legs 103, an extension portion 102 on the side of the table top 101, a stand 2 on the workbench 1, the upper parts of the stand 2 and the swing frame 3 are connected by bearings, and the middle parts are connected by cylinders 9, and the swing frame 3 can do pendulum motion with the bearing connection part of the stand 2 and the swing frame 3 as the center of the circle driven by the cylinder 9, and both sides of the upper surface of the workbench 1 are provided with sliding The movable component 6 and the sliding component 6 are both provided with sliding seats 7, and the connecting components 4 and the raw material rack components 8 are arranged in parallel between the sliding seats 7, and the connecting components 4 and the raw material rack components 8 are arranged in parallel between the sliding seats 7 on both sides of the workbench, and the connecting components 4 can rotate between the sliding seats with its axis as the center, and the raw materials are arranged on the raw material rack component 8, and the raw materials pass through the loading rack 5, and the loading rack 5 slides back and forth on the glass plate 11 with the swing frame 3 under the action of the cylinder 9, and the raw materials are reciprocated and hit on the baffle 12 of the workbench.
[0051] The connecting assembly 4 includes a connecting shaft 403, on which two through holes 402 penetrating the body are provided, and a hollow sleeve 401 is provided in the through hole 402, and the upper part of the sleeve 401 accommodates the upper shaft 306 of the swing frame 3, and the lower part of the sleeve 401 accommodates the lower shaft 502 on the loading frame 5, and the upper shaft 306 and the lower shaft 502 can slide in the sleeve 401 and have a damping sense. When the swing frame 3 swings, the motion trajectory of the bottom of the swing frame 3 is an arc. When it swings to the center, the bottom of the swing frame is closest to the table 101, and when it swings to both ends, the bottom of the swing frame is farthest from the table 101. Therefore, when the swing frame 3 swings, it not only has left-right displacement, but also up-down displacement. However, both ends of the connecting component 4 are fixed on the sliding seat 7 with bearings and can only move horizontally, but the connecting component 4 can rotate with the swing of the swing frame. If the connecting component 4, the loading rack 5 and the swing frame 3 are rigidly connected, then when the swing frame 3 swings close to the glass plate 11 on the table 101, the loading rack 5 will be pressed on the glass plate 11 and stop moving. Therefore, the sleeve 401 on the connecting component 4 is required to cooperate with the upper shaft 306 of the swing frame 3 and the lower shaft 502 on the loading rack 5. In this way, it can be ensured that when the swing frame 3 swings, the insertion depth of the upper shaft 306 and the lower shaft 502 in the sleeve 401 will also change according to its swinging position, thereby ensuring that the swing of the swing frame 3 is not affected.
[0052] The raw material rack assembly 8 is provided with raw materials, and the swing rack 3, under the action of the cylinder 9, drives the raw materials on the material rack 5 to reciprocate and hit the baffle 12 of the workbench 1 at a certain angle.
[0053] It should be noted that the vertical distance from the center of the first bearing seat 203 on the column 201 to the table 101 is the distance from the X-ray source of the actual X-ray machine to the filter plate.
[0054] like Figure 7 , 8 The stand 2 as described in 9 is arranged on the extension part 102 on one side of the workbench 1, and the stand 2 includes a base 202 and a column 201 fixed on the extension part 102, a cross bar 204 and an oblique bar 206 are arranged on the column 201, a gas rod bottom plate 207 is arranged at the intersection of the cross bar 204 and the oblique bar 206, a first pin seat 205 is arranged on the gas rod bottom plate 207, the first pin seat 205 is connected to the base pin shaft of the cylinder 9, and a first bearing seat 203 is arranged at the upper end of the column 201.
[0055] like Figure 5 and 6 The swing frame 3 is trapezoidal in shape, and includes an upper transverse tube 301 and a lower transverse tube 302. The ends of the upper transverse tube 301 and the lower transverse tube 302 are connected by an inclined tube 303 and a longitudinal tube 308. Two oblique support tubes 304 are provided between the inclined tube 303 and the longitudinal tube 308. A second pin seat 307 is provided on the longitudinal tube 308. The second pin seat 307 is connected to the gas rod pin shaft of the cylinder 9. Two upper shafts 306 are provided at the bottom of the lower transverse tube 302.
[0056] like Fig.18 As shown, the sliding assembly 6 includes slide rails 601 fixed on both sides of the workbench 1 , each slide rail 601 is provided with at least one slider 602 , and each slider 602 on the slide rail 601 is provided with a sliding seat 7 .
[0057] like Fig.19 and 20 As shown, the sliding seat 7 includes a sliding plate 701 fixed on the slider 602, and a second bearing seat 702 and a bolt seat 703 are provided on the sliding plate 701. The second bearing seat 702 is connected to the connecting shaft 403 of the connecting assembly 4 through a bearing, and the bolt seat 703 is fixedly connected to the raw material rack assembly 8.
[0058] like Fig.16 and 17 As shown, the raw material rack assembly 8 includes a support frame 801 fixed on the bolt seat 703, and the support frame 801 is provided with a material discharge device and a material receiving device;
[0059] The discharge device includes a raw material tray 804, in which raw materials are wound. The central axis of the raw material tray 804 is fixed in the bearing seat of the support frame 801 through a bearing. A suction cup 806 is provided on the top of the central axis of the raw material tray 804, and an electromagnet 807 is provided on the support frame 801 below the edge of the suction cup 806. The electromagnet 807 can absorb the suction cup 806 when energized to brake the raw material tray 804; the lower surface of the suction cup 806 has a high precision, and the gap from the upper part of the electromagnet 807 is extremely small, generally a few tenths of a millimeter.
[0060] The material collecting device includes a driving motor 802 and a waste tray 803 fixed on a support frame 801. The waste tray 803 is wrapped with a fertilizer belt. The central axis of the waste tray 803 is fixed in another bearing seat of the support frame 801 through a bearing. A gear 805 is provided on the central axis of the waste tray 803, and the gear 805 is meshed with the teeth of the reduction device on the driving motor 802.
[0061] like Figure 12-15 As shown, the loading rack 5 includes a knife plate 501, on which a feed wheel assembly 504, a knife clamping plate 503 and a lower shaft 502 are provided. The feed wheel assembly 504 is located at both ends of the knife plate 501, and a blade is provided between the two knife clamping plates 503. The lower end of the lower shaft 502 is fixed to the knife plate 501 by bolts, and the upper end extends into the sleeve 401 of the connecting assembly 4. A film heating plate 506 is provided at the lower part of the middle side of the knife plate 501. The feed wheel assembly 504 is L-shaped, and the longitudinal plate of the feed wheel assembly 504 is fixed to the knife plate 501 by bolts, and a pulley assembly 5042 is provided on the transverse plate.
[0062] The raw material is composed of three layers, the first two layers are film and lead film, and the last layer is waste tape. The thickness of the first two layers is thinner, while the thickness of the waste tape is larger and more capricious.
[0063] The raw material is wound on the raw material plate 804, passes through the pulley assembly 5042 at one end of the loading rack 5, the limit block 505, the film heating plate 506, the pulley assembly 5042 at the other end, and then passes through the tensioning wheel assembly 10 on the side of the sliding seat 7 before being wound on the waste plate 803. The tensioning wheel assembly 10 is located between the raw material rack assembly 8 and the loading rack 5.
[0064] The driving motor 802 is controlled by the controller. When the driving motor 802 is turned on, the raw material will move a fixed length along the above path. This length is larger than the width of the filter plate. It can be specifically set that the thin film heating plate 506 heats the raw material, and then the cylinder 9 is actuated to drive the swing frame 3, and then drive the loading frame 5, and the raw material will be hit on the first two layers of raw material cut off in the previous process. Due to the action of the thin film heating plate 506, after the impact, the raw material will adhere to the raw material cut off in the previous process, and as the swing frame 3 swings back, the adhered raw material will also be torn backwards. At this time, the blades between the knife plates 503 will cut off the first two layers of the raw material. At this time, the driving motor 802 is turned on, the waste belt is wound, and the new raw material is driven by the waste belt and stops at the thin film heating plate 506 again, and then swings and hits, reciprocating N times until it is not less than the required width of the filter plate.
[0065] As the number of impacts increases, the width of the filter plate becomes wider and wider, and the amplitude of the swing becomes smaller and smaller, so during the impact process, the angle of the lead film also changes continuously.
[0066] The parts not described in detail in the above content are prior art, so they are not described in detail.
