Description

Technical Field

[0001] The invention belongs to the technical field of medical and health care, and in particular relates to a dental paper sleeve packaging device and a packaging process. Background Art

[0002] Dental film is a kind of medical film and is a commonly used imaging item in medicine. Dental film uses silver halide photosensitive materials as the medium. After multiple steps such as exposure, development, fixing, and drying, a medical imaging film for diagnosis can be obtained. This wet processing technology of photosensitive imaging requires the use of reversed negatives in a darkroom under the interaction of developer and fixer to form an image. This wet processing technology has high requirements. Dental films are basically sheets. After processing, they need to be packaged. Dental packaging is usually paper, and the corners have a certain degree of stickiness, so it needs to be packaged by bonding. However, it still has the following disadvantages in actual use:

[0003] 1. The existing dental paper sleeve packaging device is basically mass-produced by manual assembly lines and machines, which not only causes high workload for workers, but also has low production efficiency;

[0004] 2. During the production of the existing dental sheet paper sleeve packaging device, the placement of the sheet material requires high hygiene, and more manual labor is involved during production, resulting in reduced hygiene.

[0005] Therefore, the existing dental paper sleeve packaging device cannot meet the needs in actual use, so there is an urgent need for improved technology in the market to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a dental paper sleeve packaging device, which solves the problems of high labor intensity for workers and failure to ensure hygiene of the production process in the existing dental paper sleeve packaging device by arranging a limiting plate, an extrusion frame, a first hydraulic cylinder, a supporting box and a fixing block.

[0007] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0008] The present invention provides a dental sheet paper sleeve packaging device, comprising a limiting disk, an extrusion frame, a first hydraulic cylinder, a supporting box and a fixed block, wherein limiting disks are arranged above both sides of the first hydraulic cylinder, a servo motor is arranged at the bottom of the limiting disk, a rotating shaft is fixed at the output end of the servo motor, the top of the rotating shaft is fixedly connected to the bottom of the limiting disk, and a pressing frame is arranged at the rear side of the limiting disk, a supporting box is arranged at the front side of the limiting disk on one side of the first hydraulic cylinder, and a fixed block is arranged at the front side of the supporting box. The present invention cooperates with two limiting disks. After a dental sheet is placed on the supporting box and the fixed block structure, the back side of the dental sheet paper sleeve pressed by one side of the first hydraulic cylinder is placed on the front side of the dental sheet on the limiting disk after the dental sheet is placed under the operation of the structure on the first hydraulic cylinder, and then the paper sheets with the dental sheet placed between the two sheets are pressed together by the structure on the extrusion frame. When the back side papers of the two paper sleeves are placed, the dental sheet is pressed out in advance at the back side position by the pressing of the structure on the extrusion frame.

[0009] Furthermore, a rotating base is fixed at the bottom of the servo motor, and clamping openings are provided on both sides of the top and the front and rear sides of the limiting disk. Four air vents are provided side by side in the same direction as the clamping opening on the limiting disk at the bottom of the clamping opening.

[0011] Furthermore, a first hydraulic column is sleeved on the upper part of the first hydraulic cylinder, a driving base is fixed on the top of the first hydraulic column, a driving motor is fixed on the top of the driving base, a driving shaft is fixed on the output end of the driving motor, a connecting column is fixed on one side of the top of the peripheral side of the driving shaft, a connecting plate is fixed on the end of the connecting column away from the driving shaft, a top box is fixed on the top of the side of the connecting plate away from the connecting column, a first air pipe is sleeved and fixed on the top center of the top box, a first suction block is fixed on the bottom of the top box, and first suction holes are evenly opened on the top of the first suction block in the top box, and the first hydraulic cylinder drives the first suction block upward and downward by driving the first hydraulic column. Under the drive of the driving motor, the top box and the first suction block are moved from one limiting disk close to the upper side of the master of ceremonies hydraulic cylinder to another limiting disk close to the upper side of the master of ceremonies hydraulic cylinder. Under the cooperation of the first air pipe and the top box, the bottom of the first suction block adsorbs and releases the paper.

[0012] Furthermore, support columns are fixed on both sides of the receiving box, film receiving openings are opened side by side on the top of the receiving box, four second pneumatic cylinders are arranged side by side at the bottom of the receiving box, the upper parts of the interiors of the second pneumatic cylinders are sleeved with second pneumatic columns, and the tops of the second pneumatic columns are fixed with lifting blocks, which are sleeved in the film receiving openings. When the lifting blocks driven by the second pneumatic cylinders and the second pneumatic columns rise, the dental film in the film receiving opening in the receiving box is driven to rise slowly.

[0013] Furthermore, two second hydraulic cylinders are symmetrically arranged at the bottom of the fixed block, the upper parts of the second hydraulic cylinders are sleeved with second hydraulic columns, the tops of the second hydraulic columns are fixedly connected to the fixed blocks, four third pneumatic cylinders are fixed side by side on the rear side of the top of the fixed block, the rear sides of the third pneumatic cylinders are sleeved with third pneumatic columns, the ends of the third pneumatic columns away from the third pneumatic cylinders are fixed with fixed connecting blocks, the ends of the fixed connecting blocks away from the third pneumatic columns are clamped and fixed with air delivery cylinders, the tops of the air delivery cylinders are fixedly connected with second air pipes, and the bottoms of the air delivery cylinders are fixed with third pneumatic cylinders.

After the adsorption is completed, the second hydraulic cylinder at the bottom of the fixed block drives the second hydraulic column upward, and the third air pressure column driven by the third air pressure cylinder on the fixed block transports the second suction block together with the dental film adsorbed thereon to the front side of the dental film paper sleeve on the limiting disk close to the receiving box which rotates to the front side of the servo motor.

[0014] A dental sheet packaging process using the dental sheet paper sleeve packaging device comprises the following steps:

[0015] (1) Cutting of dental film and wrapping paper: First, place one side of the dental film on the wrapping paper, cut it into a suitable length, turn it over on the limiting plate so that the dental film is on the top, rotate the limiting plate 90°, and then cover the dental film with another piece of wrapping paper;

[0016] (2) One-time pressing: The dental sheet with wrapping paper on both sides rotates with the limiting disk to the bottom of the first air pressure frame, and the first air pressure column presses the wrapping paper on the upper surface downward;

[0017] (3) Secondary pressing: the dental sheet and the packaging paper that have been pressed once in step (2) are turned over to the next limiting plate, rotated to the bottom of the second air pressure frame, and the second air pressure column presses down to press the packaging paper on the other side;

[0018] (4) Hot pressing and fixing: The dental sheet after the second pressing in step (3) is transferred into a hot pressing device for hot pressing and fixing, so that the packaging papers on both sides of the dental sheet are heated and bonded.

[0019] Furthermore, the pressures of the first pressing and the second pressing are consistent.

[0020] Furthermore, infrared heating is used in the heat pressing fixation.

[0021] The present invention has the following beneficial effects:

[0022] 1. The present invention solves the problem of high labor intensity of workers in the existing dental sheet paper sleeve packaging device by arranging a limiting disk, an extrusion frame, a first hydraulic cylinder, a supporting box and a fixed block. During production, the two limiting disks cooperate with each other. After the dental sheet is placed on the supporting box and the fixed block, the structure on the first hydraulic cylinder works to place the back side of the dental sheet paper sleeve pressed by one side of the first hydraulic cylinder on the front side of the dental sheet on the limiting disk after the dental sheet is placed. Then, the paper sheets with the dental sheet placed between the two sheets are pressed by the structure on the extrusion frame. When the back side papers of the two paper sleeves are placed, the dental sheet is pressed out in advance at the back side by the structure on the extrusion frame. This reduces the manual participation in the dental sheet packaging process, reduces the manual labor intensity, and greatly improves the production efficiency.

[0023] 2. The present invention solves the problem that the existing dental sheet paper sleeve packaging device cannot ensure the hygiene of the production process by providing a limiting disk, an extrusion frame, a first hydraulic cylinder, a receiving box and a fixed block. During the production process, after the front side of the paper sleeve is placed in reverse near the limiting disk on the receiving box, the dental sheet on the receiving box is immediately adsorbed by the structure on the fixed block and placed on the front side above the inside of the paper sleeve on the limiting disk. During the rotation process, the back side of the limiting disk away from the receiving box is transported by the structure on the first hydraulic cylinder and covered on the paper sheet with the dental sheet on the limiting disk. Finally, it is extruded by the structure on the extrusion frame. During the production process, the dental sheet is exposed to the air for a very short time, which greatly increases the safety of dental sheet production.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Among them Figure 1 , 5 As shown, support columns 402 are fixed on both sides of the receiving box 400, and the support columns 402 support the receiving box 400 on the bracket of the working machine. Film receiving openings 401 are opened side by side on the top of the receiving box 400, and the film receiving openings 401 receive the dental films to be packaged in the receiving box 400. Four second pneumatic cylinders 403 are arranged side by side at the bottom of the receiving box 400, and the second pneumatic cylinders 403 drive the second pneumatic columns 404 to rise.

[0041] Among them Figure 1 , 6 As shown in FIG. 7 , two second hydraulic cylinders 501 are symmetrically arranged at the bottom of the fixed block 500. The second hydraulic cylinders 501 drive the second hydraulic column 502 to move up and down. The upper part of the second hydraulic cylinder 501 is sleeved with the second hydraulic column 502. When the second hydraulic column 502 is moved up and down by the second hydraulic cylinder 501, the fixed block 500 is driven to move up and down. The tops of the second hydraulic columns 502 are fixedly connected to the fixed block 500. Four third pneumatic cylinders 503 are fixed side by side on the rear side of the top of the fixed block 500.

Under the drive of the third air pressure cylinder 503, the third air pressure column 504 moves the fixed connection block 505 back and forth in the horizontal direction, so that the second suction block 508 moves back and forth above the film receiving opening 401 and the clamping opening 101 on the rear side of the limiting disk 100 close to the side of the receiving box 400.

A second suction block 508 is fixed to the bottom of the air cylinder 506, and second suction holes 509 are provided in a rectangular array on the top of the second suction block 508 inside the air cylinder 506. When the second air pipe 507 on the air cylinder 506 generates negative pressure, the second suction block 508 contacts the dental film on the film receiving port 401 through the second suction block 508, and the dental film is adsorbed.

[0042] The working principle of the present invention is as follows: during operation, half of the back side of the dental sheet paper sleeve is placed downwardly on the clamping opening 101 on the top front side of the limiting plate 100 on the side away from the receiving box 400 through the inside of the discharge structure, and the clamping opening 101 on the limiting plate 100 on which half of the back side of the dental sheet paper sleeve is placed is rotated to the side away from the first hydraulic cylinder 300 under the drive of the servo motor 103, and the other half of the back side of the dental sheet paper sleeve is placed through the discharge device, and then driven by the servo motor 103, the two sheets of paper on the back side of the dental sheet are rotated to the bottom of the extrusion frame 200 on the side away from the receiving box 400, and the pressing block 203 is driven downward under the drive of the first pneumatic cylinder 201 and the first pneumatic column 202 on the extrusion frame 200, so that the two sheets of paper are bonded during the pressing process, and The pressure port 204 is reserved to press out the reserved position for placing the dental film. After the pressing is completed, the first pneumatic cylinder 201 drives the first pneumatic column 202 and the pressing block 203 upward, and then the servo motor 103 rotates the clamping port 101 on the limiting plate 100 with the back side of the dental film paper sleeve placed to the side close to the first hydraulic cylinder 300. While the structure on the limiting plate 100 away from the side of the supporting box 400 is working, the clamping port 101 on the side of the limiting plate 100 away from the first hydraulic cylinder 300, under the work of the discharge structure, places the front side of the dental film paper sleeve in reverse on the clamping port 101 away from the side of the first hydraulic cylinder 300. After placement, it is driven by the servo motor 103 to rotate to the front side of the servo motor 103, and then rotates to the front side of the servo motor 103. While the limiting disk 100 near one side of the receiving box 400 is working, the second pneumatic cylinder 403 at the bottom of the receiving box 400 drives the second pneumatic column 404 upward, driving the rising block 405 upward, so that the dental film in the film receiving opening 401 on the receiving box 400 moves upward, and the second hydraulic cylinder 501 at the bottom of the fixed block 500 drives the second hydraulic column 502 downward, and the second suction block 508 contacts the dental film, and under the action of the negative pressure generated by the second air pipe 507 on the air delivery cylinder 506, air is guided through the second suction hole 509 to adsorb the dental film on the bottom of the second suction block 508. After the adsorption is completed, the second hydraulic cylinder 501 at the bottom of the fixed block 500 drives the second hydraulic column 502 upward, and the third pneumatic column 504 driven by the third pneumatic cylinder 503 on the fixed block 500 adsorbs the dental film. The block 508 together with the dental film adsorbed thereon is transported to the front side of the dental film paper sleeve on the limiting disk 100 which is rotated to the front side of the servo motor 103 and close to the receiving box 400. The limiting disk 100 is then rotated by the servo motor 103 to rotate the front side of the paper sleeve with the dental film placed thereon to the side close to the first hydraulic cylinder 300. When the servo motor 103 which is far away from the receiving box 400 stops working, the first hydraulic cylinder 300 drives the first hydraulic column 301 to descend through the first hydraulic cylinder 300, so that the top box 307 on the connecting plate 306 connected to the connecting column 305 moves downward, and the first suction block 309 fixed on the top box 307 contacts the back side of the paper sleeve pressed on the limiting disk 100. Under the negative pressure generated by the first air pipe 308 on the top box 307,The reverse side of the paper sleeve pressed on the limiting disk 100 is adsorbed on it by the first suction block 309, and the power generated by the driving motor 303 is transmitted through the driving shaft 304 on the driving motor 303 on it, so that the first suction block 309 at the bottom of the top box 307 and the reverse side of the dental film paper sleeve adsorbed thereon are transported to the paper sleeve on which the dental film is placed on the limiting disk 100 near the side of the receiving box 400. At this time, the servo motor 103 under the limiting disk 100 near the side of the receiving box 400 is started, and the clamping port 101 for combining the front and back dental film papers is rotated to the rear side of the servo motor 103, and the first air pressure on the extrusion frame 200 near the side of the receiving box 400 is pressed. Under the drive of the cylinder 201 and the first air pressure column 202, the pressing block 203 is driven downward, so that the front and back dental sheet paper sleeves are pressed together, and the front and back dental sheet paper sleeves together with the dental sheet thereon are pressed together, so that the dental sheet paper sleeve is closed, and then driven by the servo motor 103, the packaged dental sheet and the packaging paper sleeve on the limiting plate 100 are rotated to the side away from the first hydraulic cylinder 300, and the packaged dental sheet and the packaging paper sleeve thereon are removed by the external adsorption structure. After removal, the external discharge structure immediately places the other front dental sheet paper on the clamping port 101 on the limiting plate 100 from which the packaged dental sheet paper sleeve has just been removed.

[0043] The dental sheet packaging process using the dental sheet paper sleeve packaging device is operated as follows:

[0044] (1) Cutting of dental film and wrapping paper: First, place one side of the dental film on the wrapping paper, cut it into a suitable length, turn it over on the limiting plate so that the dental film is on the top, rotate the limiting plate 90°, and then cover the dental film with another piece of wrapping paper;

[0045] (2) One-time pressing: The dental sheet with wrapping paper on both sides rotates with the limiting disk to the bottom of the first air pressure frame, and the first air pressure column presses the wrapping paper on the upper surface downward;

[0046] (3) Secondary pressing: the dental sheet and the packaging paper that have been pressed once in step (2) are turned over to the next limiting plate, rotated to the bottom of the second air pressure frame, and the second air pressure column presses down to press the packaging paper on the other side, and the pressure of the primary pressing and the secondary pressing is the same;

[0047] (4) Hot pressing and fixing: The dental sheet after the second pressing in step (3) is transferred to a hot pressing device for hot pressing and fixing, so that the packaging papers on both sides of the dental sheet are heated and bonded, and infrared heating is added during the hot pressing and fixing.

[0048] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments, any equivalent replacement of some of the technical features therein, and any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
