Description
Technical field
The utility model is related to a kind of feed mechanism, specifically a kind of device of feeding forward in a stepping manner.
Background technology
Current step-by-step movement feed device is substantially to be completed by stepper motor, but stepper motor has cost
Higher, the small disadvantage of motive force is held if the feeding for large scale equipment such as shredder, excessively high for the load of stepper motor
Easy failure, to also substantially increase production cost.If Patent Office is disclosed in 15 days July in 2015, Patent No.
The feed mechanism of 201520080966.0 artificial eye machine, it includes working plate, and working plate is arranged on board, the working plate
There is rack, rack is used for and gear is meshed, and the output shaft of gear and stepper motor is sequentially connected, described on first edge
Briquetting is movably equipped on board, briquetting and gear are located at the both sides of working plate, and the board has compression spring pressure section,
One end of compression spring is against on briquetting, and the other end of compression spring is against on compression spring pressure section, by compression spring make briquetting ejection working plate from
And the rack on working plate is made to be meshed with the gear.This feed mechanism is only suitable for pushing lighter object, and stepping
The cost of motor is higher.
Invention content
The purpose of this utility model is that it is in view of the above-mentioned defects in the prior art and insufficient, provide a kind of structure letter for people
The step-by-step movement feed device single, easy to operate, at low cost, thrust is big.
Technical solution adopted in the utility model is to achieve the above object：The step-by-step movement feed device, it includes branch
Frame is provided with hopper on the holder, and the end of the hopper is provided with material pushing box, unidirectional tooth is provided in the hopper
Item, is provided with pipe bending cylinder in the material pushing box, the pipe bending cylinder can opposite material pushing box be moved forward and backward, the material pushing box
On be provided with the first unidirectional gear piece that can be engaged with unidirectional rack, being provided on the pipe bending cylinder can engage with unidirectional rack
Second unidirectional gear piece.
The first unidirectional gear piece is hinged with material pushing box, and the first reset bullet is provided with above the first unidirectional gear piece
Spring, the described second unidirectional gear piece is hinged with pipe bending cylinder, and second back-moving spring is provided with above the second unidirectional gear piece.
When the pipe bending cylinder stretches out, push material pushing box Forward, when the pipe bending cylinder is shunk, drive pipe bending cylinder
Forward.
The utility model is used for shredder or other big machinery feedings, passes through the first unidirectional gear piece and the second unidirectional gear piece
With the cooperation of unidirectional rack, realizes step-by-step movement feeding, have the advantages that simple in structure, easy to operate, at low cost, thrust is big, have
Good market prospects.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram when pipe bending cylinder of the utility model stretches out.
Specific implementation mode
As shown in Figure 1 and Figure 2, the utility model is a kind of step-by-step movement feed device, it includes holder 1, the holder 1
On be provided with hopper 2, the end of the hopper 2 is provided with material pushing box 3, unidirectional rack 4 is provided in the hopper 2, described
Material pushing box 3 in be provided with pipe bending cylinder 5, the pipe bending cylinder 5 can opposite material pushing box 3 be moved forward and backward.On the material pushing box 3
It is provided with the first unidirectional gear piece 6 that can be engaged with unidirectional rack 4, being provided on the pipe bending cylinder 5 can engage with unidirectional rack 4
The second unidirectional gear piece 7.When the pipe bending cylinder 5 stretches out, the second unidirectional gear piece 7 is killed with unidirectional rack 4, pipe bending cylinder 5
It can not retreat, the Forward of dynamic material pushing box 3 is pushed in the stretching of pipe bending cylinder 5.When the pipe bending cylinder 5 is shunk, the first unidirectional gear piece 6 with
Unidirectional rack 4 is killed, and material pushing box 3 can not retreat, and 5 convergent force of pipe bending cylinder drives pipe bending cylinder 5 to move forward.It just realizes in cycles
Step feeding, and the thrust of pipe bending cylinder 5 is much larger than the power of stepper motor output.
The first unidirectional gear piece 6 is hinged with material pushing box 3, and the top of the first unidirectional gear piece 6 is provided with the first reset
Spring 8 ensures that when without other external force, the first unidirectional gear piece 6 is engaged with unidirectional rack 4.The second unidirectional gear piece 7 and top
Push oil cylinder 5 is hinged, and the top of the second unidirectional gear piece 7 is provided with second back-moving spring 9, ensures when without other external force, second
Unidirectional gear piece 7 is engaged with unidirectional rack 4.
The utility model is used for shredder or other big machinery feedings, passes through the first unidirectional gear piece 6 and the second unidirectional tooth
Step-by-step movement feeding is realized in the cooperation of piece 7 and unidirectional rack 4, has big excellent of simple in structure, easy to operate, at low cost, thrust
Point has good market prospects.
