Abstract
Description
Technical Field
[0001] The utility model belongs to the field of laboratory utensil sealing, in particular to a medicine container coating device. Background Art
[0002] Before using a rotary evaporator to distill the solvent, the drug powder needs to be placed in a container for dissolution. When the drug powder is completely dissolved in the liquid to form a solvent, the solvent is filtered through a suction bottle to remove impurities in the solvent, and then the filtered solvent is poured into the rotating bottle of the rotary evaporator and the solvent is evaporated using the rotary evaporator.
[0003] We know that most of the solvents distilled by rotary evaporator are volatile solvents. Therefore, when pouring the solvent into the liquid for dissolution, it is necessary to cover the top opening of the container with a protective film to prevent the solvent from evaporating into the air. The existing coating method is mostly done manually. The worker first tears off the protective film, and then covers the protective film on the opening at the top of the container. For containers with smaller openings, the worker can press the protective film with the palm of his hand to make it completely attached to the opening of the container. However, for containers with larger openings, the worker first covers the opening at the top of the container with the protective film, and then pulls the protective film to make it flat, and presses the pulled flat protective film along the top opening of the container to fit the protective film with the top opening of the container. In this way, press along the top opening of the container for a circle to make the protective film completely attached to the top opening of the container. However, during the pulling process, the protective film that has been attached to the outer wall of the opening may become loose, affecting the sealing of the protective film. Utility Model Content

DETAILED DESCRIPTION
[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.
[0025] like Figure 1-Figure 5 As shown, this embodiment provides a drug container coating device, including an operating table 100 and a coating assembly 200 disposed on the operating table 100 .
[0026] Specifically, Figure 1-Figure 3 As shown, the operating platform 100 includes a lifting platform 110, a plurality of positioning components 120, and a vertical plate 130. The vertical plate 130 is vertically arranged, and the lifting platform 110 is arranged on one side of the vertical plate 130. The positioning components 120 are arranged in an array on the lifting platform 110 for placing the container 1. A movable groove 131 is opened at the upper end of the vertical plate 130, and the coating component 200 is movably arranged along the movable groove 131.
[0027] The film coating assembly 200 includes a moving plate 210, a placing cylinder 220, a rolling assembly 230, and a hot melt knife 240. One end of the moving plate 210 is slidably connected to the moving groove 131. The placing cylinder 220, the rolling assembly 230, and the hot melt knife 240 are arranged at intervals on the bottom surface of the moving plate 210. The hot melt knife 240 is telescopically arranged between the placing cylinder 220 and the rolling assembly 230, and is tangent to the side of the rolling assembly 230 facing the placing cylinder 220. The telescopic movement of the hot melt knife 240 can be achieved by a linear cylinder or a linear hydraulic cylinder. The axis of the placing cylinder 220 is perpendicular to the moving direction of the moving plate 210, and is used to place the rolled protective film 2. A material guide groove 221 is provided along the axis direction of the placing cylinder 220 for the end of the protective film 2 to pass through. The rolling assembly 230 is arranged parallel to and spaced apart from one side of the placement cylinder 220 for pressing the protective film 2. The hot melt knife 240 is used to move downward along one side of the rolling assembly 230 after the rolling assembly 230 covers the protective film 2 at the top opening of the container 1, thereby cutting off the protective film 2.
[0028] When in use, the protective film 2 is placed in the placement cylinder 220, and the end of the protective film 2 is pulled out of the placement cylinder 220 along the guide groove 221, and the length of the protective film 2 pulled out is greater than the distance between the guide groove 221 and the rolling assembly 230. Then the container 1 is placed in the positioning assembly 120 for limiting, and the lifting platform 110 is started to move the positioning assembly 120 with the container 1 placed upward, so that the top opening of the container 1 is coplanar with the lower end of the rolling assembly 230, and ensure that the container 1 is located at the front end of the moving direction of the protective film 2 that extends out of the placement cylinder 220.
[0029] The moving plate 210 is started to move along the moving groove 131, and the placing cylinder 220, the rolling assembly 230, and the hot melt knife 240 move synchronously with the fixed plate 210. The placing cylinder 220 drives the protective film 2 to move to the top of the container 1. When the rolling assembly 230 enters the opening at the top of the container 1, the rolling assembly 230 presses the part of the protective film 2 extending out of the guide groove 221, and as the moving plate 210 continues to move, the protective film 2 is continuously drawn out, and the protective film 2 is covered on the opening at the top of the container 1 under the action of the rolling assembly 230. When the rolling assembly 230 is about to move out of the opening at the top of the container 1, the hot melt knife 240 is started to move vertically downward, and the protective film 2 is cut off along one side of the roller 236. After cutting, the hot melt knife 240 is automatically retracted upward.
[0030] Preferably, in order to avoid the need to manually pull the protective film 2 out of the placement tube 220 every time the film is coated, the moving trajectory of the hot melt knife 240 is tangent to one side of the rolling assembly 230, and the downward moving distance of the rolling assembly 230 is greater than the horizontal distance between the material guide groove 221 and the rolling assembly 230.
[0031] Specifically, Figure 2 As shown, the positioning assembly 120 includes a bottom plate 121, a plurality of baffles 123, and a plurality of first springs 124. The top surface of the bottom plate 121 is provided with a plurality of slide grooves 122 in a circumferential array. The lower end of the baffle 123 is slidably disposed in the slide groove 122, and the upper end protrudes upward from the top surface of the bottom plate 121, and is used to limit the side wall of the container 1. The outer end of the first spring 124 is connected to the outer end of the slide groove 122, and the other end is connected to the outer side surface of the baffle 123. The baffle 123 is set to an S-shaped structure. When the container 1 is placed on the top surface of the bottom plate 121, the top of the baffle 123 is outward. The baffles 123 extend to form an outwardly expanding opening at the upper end of the area enclosed by each baffle 123, so that the container 1 is more convenient to place and the bottom of the container 1 is prevented from colliding with the upper edge of the baffle 123. The portion of the baffle 123 with an S-shaped structure that protrudes toward the center of the bottom plate 121 contacts the middle of the container 1, and the container 1 is more stably limited. Regardless of whether the container 1 is a conical flask with a small upper end and a large lower end, or a cylindrical beaker, the baffle 123 can limit the side wall thereof.
[0032] Specifically, Figure 2-Figure 4 As shown, a first cylinder 211 is provided at one end of the movable plate 210 connected to the movable groove 131, and the first cylinder 211 is installed on the vertical plate 130. Connecting rods 222 are respectively provided at both ends of the placing tube 220, so that the upper end of the connecting rod 222 is connected to the bottom surface of the movable plate 210, and a placing groove 223 is opened on the upper side of the placing tube 220 to facilitate the protective film 2 to be placed in the placing tube 220.
[0033] Specifically, Figure 5 As shown, the rolling assembly 230 includes a second cylinder 231, a mounting plate 232, a group of support rods 233, two second springs 234, a group of mounting seats 235, and a roller 236. The second cylinder 231 is arranged on the bottom surface of the moving plate 210 and is located at one side of the connecting rod 222 at intervals. The mounting plate 232 is arranged at the output end of the second cylinder 231. The support rods 233 are respectively arranged at both ends of the bottom surface of the mounting plate 232. The second spring 234 is penetrated on the support rod 233. The mounting seat 235 is located at the lower end of the second spring 234 and is slidably matched with the support rod 233. A point stop block is arranged at the lower end of the support rod 233 to support the mounting seat 235. The two ends of the roller 236 are respectively rotatably connected with one mounting seat 235.
[0034] When in use, the first cylinder 211 pushes the movable plate 210 to move along the movable groove 131, the roller 236 moves to the top of the container 1, and presses the protective film 2 to stick to the opening at the top of the container 1. During the movement, the roller 236 remains in contact with the opening at the top of the container 1 under the action of the second spring 234, which not only makes the protective film 2 fit better with the opening at the top of the container 1, but also can buffer the impact force generated when the roller 236 just contacts the opening at the top of the container 1, thereby effectively protecting the container 1.
[0035] Specifically, Figure 3 , Figure 5 As shown, a group of relatively arranged guide grooves 237 are provided along the length of the bottom surface of the mounting plate 232 , and a welt wheel assembly 250 is vertically arranged in the guide groove 237 .
[0036] When the roller 236 presses the protective film 2 against the opening at the top of the container 1, the edging wheel assembly 250 rolls along the side wall of the container to press the protective film 2 protruding from the edge of the top opening of the container 1 to fit against the outer wall of the container 1 to further improve the sealing.
[0037] The wedging wheel assembly 250 includes a guide rod 251, a third spring 252, a movable seat 253, and a wedging wheel 254. The guide rod 251 is arranged in the guide groove 237, and the third spring 252 is sleeved on the guide rod 251. One end of the third spring 252 is connected to one side of the movable seat 253, and the other end is connected to the outer end of the guide groove 237. The wedging wheel 254 is detachably arranged at the lower end of the movable seat 235, and the wedging wheel 254 is rotatably connected to the movable seat 235. The wedging wheel 254 can move along the length direction of the mounting plate 232. When in use, the wedging wheel 254 is kept in close contact with the top opening of the container 1 under the action of the third spring 252, so that the protective film 2 is in contact with the outer wall of the top of the container 1. When the container 1 is conical, the wedging wheel 254 can be replaced with a conical structure. When the container 1 is cylindrical, the wedging wheel 254 can be replaced with a cylindrical structure.
[0038] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
