Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical processing equipment technology, and more specifically, to a tunnel-type sterilization dryer for pharmaceutical processing. Background Technology
[0002] Tunnel-type sterilization dryers are one of the key pieces of equipment in modern aseptic pharmaceutical production lines. Their function is to dry and sterilize cleaned pharmaceutical glass containers (such as vials) at high temperatures before they are sent to the aseptic filling area. The equipment typically consists of a preheating section, a high-temperature sterilization section, and a cooling section, with a conveyor belt carrying glass vials through these three areas in sequence.
[0003] In existing tunnel-type sterilization dryers, medicine bottles are fixed on the conveyor belt and their posture cannot be changed. This results in the sterilization and drying medium not being able to act on all parts of the medicine bottle in a comprehensive and even manner, which easily creates sterilization and drying dead zones. In particular, the bottom, recessed parts and the inner side of special structures of the medicine bottle are not sterilized and dried thoroughly, making it difficult to meet the quality standards of pharmaceutical production. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a tunnel-type sterilization and drying machine for pharmaceutical processing, so as to solve the technical problem that the current fixed position of the medicine bottle conveying position easily forms a sterilization and drying dead corner.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A tunnel-type sterilization dryer for pharmaceutical processing includes a conveyor belt, a sterilization dryer body is fixedly installed on the outer side of the conveyor belt, a plurality of base plates are fixedly provided on the surface of the conveyor belt, and a shelf for limiting medicine bottles is installed on the side of each base plate. Toothed racks are arranged symmetrically on the top inner wall of the sterilization dryer body. The shelf includes a base, and support plates are fixedly installed on both sides of the top of the base. Clamping components for holding medicine bottles are rotatably installed between the opposing surfaces of the support plates on both sides. Gears that are fixedly connected to the clamping components are fitted to the opposing sides of the support plates on both sides, and the gears on both sides mesh with the teeth of the rack.
[0006] The core advantage of this invention, through its reversible medicine bottle technology, lies in breaking the limitation of the "fixed posture" of medicine bottles in traditional equipment. As the conveyor belt moves the shelf, the gears on both sides of the shelf mesh with the rack on the inner wall of the sterilization dryer's main body, driving the clamping components to rotate synchronously with the medicine bottle (the rotation angle can be flexibly controlled by the rack length and the number of gear teeth to meet different sterilization and drying needs). During this dynamic reversal process, various parts of the medicine bottle (including the bottom, recessed areas, and the inner side of the bottle neck, which are difficult to cover in traditional equipment) are alternately exposed to the sterilization and drying medium (hot air, ultraviolet light, etc.), completely eliminating sterilization and drying dead zones.
[0007] Preferably, the clamping member includes a rotating member that passes through both support plates. A first clamping plate and a second clamping plate that movably cooperate with the first clamping plate are fixedly connected between the two rotating members. An adjusting screw is rotatably installed between the plates of the second clamping plate, and the adjusting screw is threadedly connected to the first clamping plate. The sides of the first clamping plate and the second clamping plate that are in contact with each other are provided with matching clamping grooves.
[0008] Preferably, a plurality of anti-slip strips are arranged in an array on the inner walls of the clamping grooves on both sides, and the anti-slip strips are made of rubber.
[0009] Preferably, a positioning rod that penetrates the side wall of the first clamping plate is fixedly provided on the side of the second clamping plate, and sliders that slide in cooperation with the rotating component are fixedly provided on opposite sides of the second clamping plate.
[0010] Preferably, positioning blocks are fixedly provided on both sides of the top of the base plate, positioning holes that engage with the positioning blocks are opened at the bottom of the shelf, and a number of elastic support members supporting the bottom of the medicine bottles are arranged in an array on the top of the conveyor belt, and through holes for the elastic support members to pass through are opened on the plate wall of the base.
[0011] Preferably, each of the elastic supports includes a sleeve, a spring is fixedly connected to the bottom of the inner cavity of the sleeve, and a ball is fixedly disposed on the top of the spring.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The core advantage of this utility model, through its reversible medicine bottle technology, lies in breaking the limitation of the "fixed posture" of medicine bottles in traditional equipment. As the conveyor belt moves the shelf, the gears on both sides of the shelf mesh with the rack on the inner wall of the sterilization dryer's main body, driving the clamping components to rotate synchronously with the medicine bottle (the rotation angle can be flexibly controlled by the rack length and the number of gear teeth to meet different sterilization and drying requirements). During this dynamic reversal process, various parts of the medicine bottle (including the bottom, recessed areas, and the inner side of the bottle neck, which are difficult to cover in traditional equipment) are alternately exposed to the sterilization and drying medium (hot air, ultraviolet light, etc.), completely eliminating sterilization and drying dead zones.
[0013] 2. This utility model also allows for spacing adjustment between the first and second clamping plates in the clamping component via an adjusting screw. Rotating the adjusting screw changes the distance between the two clamping plates, enabling stable clamping of medicine bottles of different diameters (such as oral liquid bottles, injection bottles, etc.). This eliminates the need to replace special clamps for different bottle sizes, significantly improving the equipment's adaptability to processing various medicines and reducing the time and equipment investment costs incurred by companies due to clamp replacements. Simultaneously, the clamping grooves on the contact surfaces of the two clamping plates fit snugly against the outer wall of the medicine bottle, increasing the clamping contact area. Combined with the rubber anti-slip strips on the inner wall of the clamping grooves, this effectively prevents the medicine bottle from slipping or falling off during flipping and conveying, reducing losses from collisions and breakage.

[0016] like Figures 1 to 7As shown, this utility model relates to a tunnel-type sterilization and drying machine for pharmaceutical processing, including a conveyor belt 1. A sterilization and drying machine body 2 is fixedly installed on the outer side of the conveyor belt 1. Several base plates 101 are fixedly arranged on the surface of the conveyor belt 1. Each base plate 101 has a shelf 3 for limiting medicine bottles installed on its side. A toothed rack 4 is centrally symmetrically arranged on the top inner wall of the sterilization and drying machine body 2. The design of the base plates 101 can limit the position of the shelf 3, so that medicine bottles can be fixed on the shelf 3 offline, allowing the medicine bottles to be placed on the surface of the conveyor belt 1 at a uniform speed for conveying. The conveyor belt 1 and the sterilization and drying machine body 2 are existing technical structures and will not be described in detail here. The shelf 3 includes a base 301, with support plates 302 fixedly installed on both sides of the top of the base 301. Clamping components 5 for holding medicine bottles are rotatably installed between the opposing surfaces of the two support plates 302. Gears 6 fixedly connected to the clamping components 5 are fitted to the opposite sides of the two support plates 302, and the gears 6 on both sides mesh with the teeth of the rack 4. By engaging the rotatably installed clamping components 5 with the gears 6, they can contact the rack 4 during movement, thereby automatically flipping the medicine bottles on the shelf 3 under the engagement of the teeth, thus reducing sterilization dead corners and improving sterilization effect.
[0017] In an embodiment of this utility model, the clamping member 5 includes a rotating member 501 that passes through the two side support plates 302. A first clamping plate 502 and a second clamping plate 503 that are movably engaged with the first clamping plate 502 are fixedly connected between the two rotating members 501. An adjusting screw 504 is rotatably installed between the plates of the second clamping plate 503, and the adjusting screw 504 is threadedly connected to the first clamping plate 502. The sides of the first clamping plate 502 and the second clamping plate 503 that are in contact with each other are provided with matching clamping grooves 505. The distance between the clamping grooves 505 on both sides can be adjusted by the action of the adjusting screw 504, so as to achieve stable clamping of medicine bottles of different sizes.
[0018] In the embodiments of this utility model, a plurality of anti-slip strips 506 are arranged in an array on the inner walls of the clamping grooves 505 on both sides, and the anti-slip strips 506 are made of rubber; this can increase the protection of the medicine bottle during the clamping process, and also increase the frictional resistance of the clamping.
[0019] In an embodiment of this utility model, a positioning rod 507 that penetrates the side wall of the first clamping plate 502 is fixedly provided on the side of the second clamping plate 503, and sliders 508 that slide in cooperation with the rotating component 501 are fixedly provided on the opposite sides of the second clamping plate 503; the stability of the displacement of the second clamping plate 503 can be improved by the cooperation.
[0020] In this embodiment of the utility model, positioning blocks 102 are fixedly provided on both sides of the top of the base plate 101, and positioning holes 304 that engage with the positioning blocks 102 are opened at the bottom of the shelf 3. Several elastic support members 7 that support the bottom of the medicine bottle are also arranged in an array on the top of the conveyor belt 1. Through holes 303 for the elastic support members 7 to pass through are opened on the plate wall of the base 301. The bottom of the medicine bottle can be supported by the elastic support members 7, and space for flipping is reserved.
[0021] In the embodiments of this utility model, each elastic support 7 includes a sleeve 701, a spring 702 is fixedly connected to the bottom of the inner cavity of the sleeve 701, and a ball block 703 is fixedly provided on the top of the spring 702; the ball block 703 is easily pressed down, compressing the spring 702 and reducing the contact area with the medicine bottle.
[0022] Working Principle: This embodiment provides a tunnel-type sterilization and drying machine for pharmaceutical processing. Before sterilizing and drying medicine bottles, the bottles must be accurately positioned and fixed on the equipment. First, the operator installs the rack 3 onto the base plate 101. During installation, the positioning blocks 102 on both sides of the top of the base plate 101 precisely align with the positioning holes 304 at the bottom of the rack 3. This positioning structure ensures that the rack 3 will not shift laterally or longitudinally on the base plate 101, laying the foundation for stable clamping of the medicine bottles. Next, the clamping components 5 are adjusted to fit the size of the medicine bottles according to their diameter. The operator rotates the adjusting screw 504. Since the adjusting screw 504 is threadedly connected to the first clamping plate 502, under the action of the threaded transmission, the adjusting screw 504 will push the second clamping plate 503 to move along the extension direction of the positioning rod 507 (the positioning rod 507 passes through the side wall of the first clamping plate 502, which can prevent the second clamping plate 503 from rotating and shifting during movement). At the same time, the slider 508 on the side of the second clamping plate 503 will slide on the rotating part 501, further ensuring the stability of the movement of the second clamping plate 503. By adjusting the distance between the first clamping plate 502 and the second clamping plate 503, the clamping grooves 505 opened on the sides of both can perfectly fit the outer wall of the medicine bottle, and the rubber anti-slip strips 506 arranged in an array on the inner wall of the clamping grooves 505 will increase the friction between the medicine bottle and the medicine bottle, preventing the medicine bottle from sliding or falling off during subsequent transportation and flipping. Once the medicine bottle is securely clamped within the clamping groove 505 of the clamping member 5, the conveyor belt 1 starts moving, driving the base plate 101, the shelf 3 mounted on the base plate 101, and the medicine bottle together into the sterilization and drying machine body 2. During the conveying process, the gears 6 on the opposite sides of the support plates 302 on both sides of the shelf 3 mesh with the racks 4 symmetrically arranged on the inner top wall of the sterilization and drying machine body 2. As the conveyor belt 1 continues to move, the gears 6 rotate under the action of the teeth of the racks 4. Since the gears 6 are fixedly connected to the rotating part 501 of the clamping member 5, the rotation of the gears 6 drives the rotating part 501 to rotate synchronously, thereby causing the first clamping plate 502 and the second clamping plate 503 fixedly connected to the rotating part 501, as well as the clamped medicine bottle, to rotate together. This rotational motion ensures that all sides of the medicine bottle are evenly exposed to the sterilization medium and drying airflow inside the sterilization and drying machine body 2, avoiding incomplete sterilization or uneven drying in certain areas of the medicine bottle, and significantly improving the sterilization and drying effect. When the medicine bottle enters the sterilization and drying machine body 2 along with the conveyor belt 1, the sterilization and drying machine body 2 will start the internal sterilization and drying system (such as high temperature heating device, ultraviolet sterilization device, hot air circulation device, etc., depending on the equipment design) to sterilize and dry the medicine bottle.Throughout the sterilization and drying process, the bottles rotate continuously due to the meshing of gear 6 and rack 4. The surface and interior of the bottles (if open-topped) are thoroughly sterilized and dried without any blind spots, ensuring the sterilization effect meets the standards for pharmaceutical production. Simultaneously, it quickly removes moisture from the bottle surface, meeting the requirements of subsequent filling or packaging processes. During the conveying and sterilization drying process, the elastic supports 7 arranged in an array at the top of the conveyor belt 1 provide auxiliary support for the bottles. The sleeve 701 of the elastic support 7 is fixed to the conveyor belt 1. When the bottle is clamped on the rack 3, the bottom of the bottle contacts the ball block 703 of the elastic support 7. At this time, the ball block 703 compresses the spring 702 downwards under the weight of the bottle, and the spring 702 generates an upward elastic reaction force, which is transmitted to the bottom of the bottle through the ball block 703, providing an upward support force for the bottle. This elastic support structure reduces the pressure of the medicine bottle on the clamping member 5, preventing deformation or damage due to prolonged pressure from the bottle's weight and extending its service life. Furthermore, during bottle rotation, the ball block 703 rotates flexibly, neither hindering the bottle's movement nor hindering its stability, preventing wobbling or tilting and ensuring stability and safety during sterilization and drying. Simultaneously, the perforation 303 on the base 301 of the shelf 3 allows the ball block 703 of the elastic support member 7 to pass smoothly through and contact the bottom of the bottle, ensuring proper auxiliary support. After the medicine bottle has been sterilized and dried, the conveyor belt 1 will continue to transport the medicine bottle to the outside of the sterilization and drying machine body 2. After the medicine bottle is removed from the equipment, the operator can rotate the adjusting screw 504 in the opposite direction to separate the second clamping plate 503 from the first clamping plate 502, thereby removing the processed medicine bottle and completing the entire medicine sterilization and drying process.
