Description

Technical Field

[0001] This utility model relates to the field of automated transportation technology, specifically to a lifting mechanism. Background Technology

[0002] Vertical material transport typically includes the following methods: Elevators, which work by fixing material onto a chain or belt and moving it up and down via a drive unit; reciprocating elevators, such as those used in elevators and lifts, which use a motor to drive a car that moves vertically back and forth on guide rails, allowing material to be transported between levels; and screw conveyors, which use the rotation of screw blades to propel material upwards along a fixed casing, suitable for powdery or granular materials. However, these methods are not suitable for vertical material transport on a production line, such as transporting materials between upper and lower machine frames. Utility Model Content

The two pairs of rollers are respectively fixedly arranged at the two ends of the drive shaft and the driven shaft. The pair of conveyor belts are tensioned and wound around the rollers located on the same side of the drive shaft and the driven shaft. The motor drives the drive wheel to rotate, thereby driving the belt to move. The belt drives the driven wheel and the drive shaft fixedly connected to the driven wheel to rotate. The rotation of the drive shaft causes the rollers located at its two ends to rotate, thereby driving the third belt to move. The material box is placed on the belt, thereby sending the material box out of the material box conveying mechanism.

[0007] A cable drag chain is also provided on the side of the lifting cylinder, and a gear is provided on the mounting plate. The cable drag chain meshes with the gear.

[0021] Reference Figure 1-2 The lifting mechanism 100 is located between the upper and lower frames and is used to transport materials between the upper and lower frames 1 and 2 during the automated production process.

[0022] Reference Figure 3 The lifting mechanism 100 includes a lifting cylinder 110, which is mounted on the side frames of the upper and lower frames 1 and 2. The top of the piston rod of the lifting cylinder 110 is fixed to a mounting plate 101. Two guide columns 120 are arranged parallel to each other on both sides of the lifting cylinder 110. The bottom and top ends of the guide columns 120 are respectively fixed to the side frames of the upper and lower frames 1 and 2. A pair of fixing members 121 are fixed on the two guide columns 120, and two pairs of sliding members 123 are slidably sleeved on them. The fixing members 121 are fixedly mounted on the mounting plate 101, and the two pairs of sliding members 123 are respectively fixedly connected to a connecting column 124. The connecting column 124 and the mounting plate 101 are arranged perpendicular to the guide columns 120 and parallel to each other. The two connecting columns 124 are arranged parallel to each other vertically. A side plate 125 is fixedly mounted on both ends of the connecting column 124, and the two side plates 125 are relatively parallel. Two lifting mounting seats 126 are respectively installed on the opposite sides of the two side plates 125. The two lifting mounting seats 126 are located between the upper and lower frames. A material box conveying mechanism 130 is installed between the two lifting mounting seats 126.

[0023] Preferably, the two lifting mounting seats 126 are fixedly connected by a connecting plate 127, thereby enhancing their stability.

[0024] During operation, a material box (not shown) is placed on the material box conveying mechanism 130. The lifting cylinder 110 drives its piston to extend or retract, thereby pulling the sliding member 123 up and down along the guide column 121. This drives the connecting column 124 fixed to the sliding member 123, the side plates 125 fixed on both sides of the connecting column 124, the lifting mounting seats 126 installed on the side plates 125, and the material box conveying mechanism 130 installed between the two lifting mounting seats 126 to rise and fall, thereby transporting the material box between the upper and lower frames.

[0025] The material box conveying mechanism 130 includes a conveying motor 131, a drive wheel 132, a driven wheel 133, a belt 134, a drive shaft 135, a driven shaft 136, two pairs of rollers 137, and a pair of conveyor belts 138. The motor 131 is mounted on a connecting plate 127, and the drive wheel 132 is fixedly mounted on the motor shaft of the motor 131. The driven wheel 133 is fixedly mounted on the drive shaft 135, and the belt 134 is tensioned and wound around the drive wheel 132 and the driven wheel 133. The drive shaft 135 and the driven wheel 133 are perpendicular to two lifting mounting seats 126 and are respectively connected to the two ends of the two lifting mounting seats 126. The two pairs of rollers 137 are respectively fixedly disposed at the two ends of the drive shaft 135 and the driven shaft 136. The pair of conveyor belts 131 are tensioned and wound around the rollers 137 on the same side of the drive shaft 135 and the driven shaft 136. Motor 131 drives drive wheel 132 to rotate, thereby moving belt 134. Belt 134 drives driven wheel 133 and drive shaft 135 fixedly connected to driven wheel 133 to rotate. The rotation of drive shaft 135 causes rollers 137 at both ends to rotate, which in turn drives belt 134 to move. Material box 2 is placed on belt 134, thereby sending material box 2 out of material box conveying mechanism 130.

[0026] A cable drag chain 140 is also provided on the side of the lifting cylinder 110. Specifically, a gear 102 is provided on the mounting plate 101, and the cable drag chain 140 meshes with the gear 102. One end 141 of the cable drag chain 140 is fixed to the side frame of the lower rack, and the other end 142 is fixed in a storage frame 143. The storage frame 143 is fixedly mounted on the connecting column 124 and rises and falls with the connecting column 124, thereby storing the other end 142 of the cable drag chain 140 in the storage frame 143 or extending it out of the storage frame. The cable drag chain 140 is used to protect the cable and prevent the cable from getting tangled and broken during repeated lifting and lowering.

The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model and should not be construed as limiting the specific implementation of this utility model to these descriptions. For those skilled in the art, the structural form of this utility model can be flexibly varied without departing from its concept, leading to the development of a series of products. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
