Description

Technical Field

[0001] The utility model relates to the field of desiccant delivery equipment, in particular to an automatic desiccant docking device. Background Art

[0002] During the production and use of health foods, desiccant needs to be placed inside the health foods to ensure the dryness of the package and prevent moisture in the package from affecting the quality of the food. In the current automated continuous production of the pharmaceutical bottling line, a rolled desiccant belt is placed on the desiccant dispenser, and the desiccant is put into the medicine bottle through the desiccant dispenser, which can automatically realize the desiccant conveying positioning, desiccant cutting, and directional drop of the desiccant into the bottle. When the desiccant belt of the desiccant dispenser is used up, a new desiccant belt needs to be added. The current way to replace the desiccant is to alarm the operator to replace it after the desiccant is used up. It takes 5-10 minutes for the operator to find the alarm reminder signal, replace the desiccant, and eliminate the alarm signal. For the automated production line where every second counts, it is bound to delay a long time. The replacement of the desiccant belt requires human operation, which not only increases the company's labor costs, but also requires entering the machine to manually replace the desiccant, which poses certain safety hazards, such as accidental injury, jamming, etc. Due to the interference of human factors, quality differences or operational errors are inevitable during operation, resulting in product quality decline or equipment failure, which consumes a lot of time and affects production progress and efficiency.

[0014] like Figure 1-8As shown, a desiccant automatic docking device includes a frame 1, on which a feeding structure 2, a welding structure 3, a positioning structure 4 and a material conveying structure 5 are installed in sequence from left to right. The material conveying structure 5 includes an upper synchronous belt 501 and a lower synchronous belt 502 that can clamp and convey a desiccant belt up and down, and a first driving device 503 that drives the upper synchronous belt 501 and the lower synchronous belt 502. The positioning structure 4 includes a support seat 401 for supporting the desiccant belt to pass through, and sensors 402 for detecting the spacing between desiccants in the desiccant belt are provided on the upper and lower sides of the support seat. The welding structure 3 is provided on the upper and lower sides of the support seat. The structure 3 comprises a welding platform 301 installed on a frame for placing a desiccant tape, a welding fixing plate 302 is vertically provided on one side of the welding platform, a welding guide rail 303, a guide rail plate (304) moving up and down relative to the welding guide rail, and a second driving device 305 driving the guide rail plate to move up and down, and a welding piece 306 is installed on the guide rail plate. The feeding structure 2 comprises a disc 201 for placing a desiccant tape roll, a positioning table 202 relative to the welding structure for driving the desiccant tape to be placed at a welding position, and a conveying cylinder 203 driving the positioning table to approach the welding structure. First, a new desiccant belt is pre-placed on the disc and the head end of the desiccant belt is placed on the positioning platform. The conveying structure is used as a power to convey the previous roll of desiccant belt from left to right using the upper and lower synchronous belts. During the conveying process, the sensor of the positioning structure is used to position the desiccant belt to ensure that the spacing of each conveying is consistent, which is convenient for calculating the time of using up a roll of desiccant. When a roll of desiccant is used up, the last section of desiccant to the welding position is accurately found through the positioning structure calculation, and the upper and lower synchronous belts are used to slowly convey it. When the desiccant reaches the welding position of the welding structure, the pre-placed desiccant is pushed to the welding position of the welding structure by the conveying cylinder, and the welding parts in the welding structure are used for welding to complete the connection of the two ends. The utility model has a simple structure, effectively reduces the time consumed by manual labor to reach the work station to replace the desiccant, and improves the production efficiency of the continuous production line.

[0015] The first driving device is a motor, the second driving device can be a cylinder or a motor, and the point driving device can be a cylinder or a motor.

[0016] The positioning platform 202 is provided with a suction cup that can absorb the desiccant tape, and the desiccant tape can be firmly sucked by the suction cup and transported to the welding position.

[0017] A roller assembly for tightening the desiccant belt and a placement table 204 for placing the desiccant belt on the same level as the positioning table are provided in sequence from left to right between the disc 201 and the positioning table 202. A pressing device 205 is provided above the placement table. The roller assembly includes two conveying guide wheels 206 and a tensioning guide wheel 207 that can move up and down and is placed between the two conveying guide wheels. In-position sensors are provided on the upper and lower sides of the tensioning guide wheel. After the desiccant belt passes through the conveying guide wheel, the tensioning guide wheel and the conveying guide wheel in sequence, the desiccant belt has tension due to the action of the disc and the material conveying structure. Under the action of the tension, the tensioning guide wheel is located at the in-place sensor on the upper side. When the desiccant on the disc is about to run out and detaches from the disc, one end of the desiccant belt will sag and lose the tension, which will affect the positioning detection of the positioning structure. Therefore, after losing the tension, the tensioning guide wheel will move downward to the in-place sensor on the lower side, triggering the downward pressure device to clamp the desiccant belt, so that the desiccant belt maintains a tight tension to facilitate the positioning detection of the positioning structure.

[0018] The feeding structure 2 also includes a switching fixed seat 208 vertically arranged on the frame, a guide rail 209 vertically arranged on the switching fixed seat, a switching fixed guide rail plate 210 that moves up and down relative to the guide rail, and a third driving device 211 that drives the switching fixed guide rail plate to move up and down. Two discs, two positioning tables corresponding to the discs and a conveying cylinder are provided on one side of the switching fixed guide rail plate. By setting up two discs, two rolls of desiccant tapes can be placed. By using the switching fixed guide rail plate to switch up and down and the positioning table docked with the welding structure, the window time for replacing the desiccant tape can be avoided.

[0019] The welding structure 3 also includes an adjustment mechanism 307 installed on the guide plate for fixing and adjusting the horizontality of the welding part. The adjustment mechanism includes an annular ring platform 308 and a hemispherical fixed platform 309 placed in the ring platform. A plurality of adjustment screws 310 are arranged around the bottom of the ring platform and are abutted against the bottom of the hemispherical fixed platform. The welding part is fixed through the middle of the hemispherical fixed platform, so that the welding part can adjust the horizontality according to the flatness of the ground, thereby improving the welding quality.

[0020] The positioning structure 4 also includes a guide groove 403 placed above the support seat for guiding the desiccant belt, so that the desiccant belt can pass through the positioning structure smoothly in sequence, avoiding the desiccant belt from bulging and bending, affecting the spacing of the sensor detecting the desiccant, and improving the detection accuracy.

[0021] The material conveying structure 5 also includes a cylinder 504 for driving the upper synchronous belt 501 downward. The cylinder and the upper synchronous belt are connected via a fixed plate 505. The cylinder presses downward so that the upper synchronous belt and the lower synchronous belt can stably clamp and convey the desiccant belt, thereby improving the conveying efficiency.

[0022] Furthermore, the upper synchronous belt 501 and the lower synchronous belt 502 rotate synchronously, the upper synchronous belt 501 is connected to the crankshaft coupling 506, and the lower synchronous belt 502 is connected to the transmission shaft 507, and also includes a transmission shaft positioning plate 508 for installing the crankshaft coupling and the transmission shaft, and the crankshaft coupling and the transmission shaft are sleeved with mutually meshing gears 509, and the transmission shaft is also connected to the first drive device. Through the cooperation of the crankshaft coupling, the transmission shaft and the gears, the upper synchronous belt and the lower synchronous belt can rotate synchronously, and the crankshaft connector, that is, the two ends are hinged structures, so that the crankshaft coupling can adapt to deformation and adjustment as the upper synchronous belt moves up and down.
