Description

[Technical field]

[0001] The utility model relates to the field of packaging equipment, in particular to a desiccant feeding device. [Background technology]

[0002] In packaging products, a desiccant bag containing desiccant is generally required to maintain a dry environment. In the prior art, a desiccant bag inserting machine is used to insert desiccant bags into food or medicine packaging bags. Its working process is as follows: the desiccant bag roll is placed on the desiccant bag tray, and the desiccant bag belt pulled out from the desiccant bag tray is conveyed to the bag guide device. Before the desiccant bag belt enters the shearing system through the bag guide device, it is fixed in length according to the length of each bag and then conveyed to the shearing system. After being cut by the scissors of the shearing system, the desiccant bags are inserted into the bottles one by one. This machine can be used as a connecting device for the filling production line of medicines, foods, etc., and can also be used for bagging other sealed containers that need to be filled with desiccant bags.

[0003] At present, the cutter is driven by a linear drive such as a cylinder. Patent application number: CN202222371601.6 discloses a desiccant feeding device, including a baffle fixed on a frame, a screw is arranged on the frame on one side of the baffle, the screw is driven to rotate by a conveying motor, a first conveying trough and a second conveying trough are spirally arranged on both sides of the screw, the first conveying trough and the second conveying trough are connected by a positioning groove, the positioning groove is arranged in a vertical direction, and a cutting device is arranged on the frame above the positioning groove, the cutting device includes a cylinder fixed on the frame, a cutter is fixed at the end of the piston rod of the cylinder, and a knife holder used in conjunction with the cutter is also fixed on the frame. This type of cylinder linear drive method is limited in speed during the extension and contraction process. For example, the speed limit of the cylinder intake and exhaust is about 200 reciprocating times per minute, which affects the speed of the entire line, and the cylinder has a short life due to factors such as the solenoid valve and the long-term movement of the piston, and is prone to failure, and often requires maintenance and replacement.

[0004] The utility model is proposed in view of the deficiencies in the prior art. [Contents of the utility model]

[0005] The utility model aims to overcome the above-mentioned shortcomings of the prior art and provides a desiccant feeding device.

[0006] The utility model can be realized by the following technical solutions:

[0007] The utility model discloses a desiccant feeding device, comprising a frame, a feeding shaft is arranged on the frame, a conveyor belt is also arranged on the frame, the conveyor belt is driven to rotate by a conveying motor, a fixed plate is also arranged on the frame, a mounting plate is also arranged between the fixed plate and the conveyor belt, two positioning rollers are arranged on the mounting plate, the two positioning rollers are connected by the positioning belt, a limiting plate is also arranged between the mounting plate and the fixed plate, a plurality of springs are also fixed between the limiting plate and the mounting plate, a plurality of positioning rods are also fixed on the fixed plate, the positioning rods pass through the limiting plate and are slidably connected with the limiting plate, a cutting device is also arranged on the frame below the conveyor belt, the cutting device comprises a knife seat fixed on the frame, a cutting motor is fixed on the frame on one side of the knife seat, a rotating disk is fixed on the output end of the cutting motor, an eccentric shaft is fixed on the rotating disk, a slide plate slidably connected with the frame is also arranged on the frame, a cutting knife used in conjunction with the knife seat is fixed on the slide plate, and the eccentric shaft is connected to the slide plate through a push rod. The desiccant material tray is placed on the discharge shaft. The desiccant material belt is pulled out from the material tray and passes through between the positioning belt and the conveyor belt. The positioning belt is pushed by the spring to squeeze the material belt on the conveyor belt. The conveyor belt is driven to rotate by the conveying motor. When the conveyor belt rotates, the desiccant material belt is pulled out from the material tray and conveyed between the cutter and the knife seat. The turntable is driven to rotate by the cutting motor. The eccentric shaft on the turntable rotates with the turntable. When the eccentric shaft rotates around the axis of the turntable, the eccentric shaft pushes the slide plate to move back and forth through the push rod. The cutter on the slide plate moves with the slide plate. The desiccant material belt is cut into single desiccant by the cooperation of the cutter and the knife seat. After the desiccant is cut into single desiccant, it falls into the bottle below. The device drives the turntable to rotate by the motor, and the eccentric shaft on the turntable pushes the cutter to cooperate with the knife seat to cut the desiccant material belt into single desiccant. High-speed and stable unloading of desiccant can be achieved.

[0008] Preferably, the fixing plate is further provided with a screw rod rotatably connected to the fixing plate, and the screw rod passes through the limiting plate and is threadedly connected to the limiting plate. By rotating the screw rod, since the screw rod passes through the limiting plate and is threadedly connected to the limiting plate, when the screw rod rotates, the limiting plate moves in the direction of the screw rod, thereby adjusting the distance between the limiting plate and the mounting plate, realizing the compression state of the adjustment spring, thereby realizing the adjustment of the strength of the positioning belt to squeeze the desiccant material belt, meeting the requirements of desiccant feeding with different thicknesses.

[0009] Preferably, a cylinder is fixed on the frame below the slide, and a support plate is fixed to the end of the piston rod of the cylinder. When there is no bottle below the cutter, the cylinder is started, the piston rod on the cylinder is extended, and the support plate is extended to the bottom of the cutter to collect the fallen desiccant, so as to prevent the desiccant from falling onto the conveyor belt of the bottle and interfering with the movement of the bottle.

[0010] Preferably, the frames on both sides above the conveyor belt are symmetrically provided with limit rollers. The desiccant belt passes between the two limit rollers, and the limit rollers pull the desiccant belt to prevent the desiccant belt from moving due to inertia, thereby ensuring the smooth movement of the desiccant belt.

[0011] Compared with the existing technology, the utility model has the following advantages:

[0012] The device drives the turntable to rotate through a motor, and the eccentric shaft on the turntable drives the cutter to cooperate with the knife seat to cut the desiccant material belt into individual pieces, so as to realize high-speed feeding of the desiccant.
