Cutting device for refrigerator water channel rubber ring

Abstract

The invention discloses a cutting device used for a refrigerator water channel rubber ring. The cutting device comprises a rack, a cutting knife, a cutting base, a power mechanism, a slide slot and a pressure plate, wherein a knife head of the cutting knife is connected in the pressure plate in a sliding mode, and passes through the pressure plate; a first spring is connected between the pressure plate and the cutting knife; a groove used for buffering the knife head of the cutting knife is formed in the cutting base; a buffer cushion is arranged in the groove; the cutting knife is connected with a pushing rod; one end of the pushing rod is rotatably connected with a first roller wheel; a wedge rod which slides vertically is connected on the rack; the top end of the wedge rod is rotatably connected with a second roller wheel; the first roller wheel abuts against the wedge surface of the wedge rod; the power mechanism comprises an electromagnet, a permanent magnet, a conductive block, a crankshaft and a crankshaft base; the crankshaft is rotatably connected onto the crankshaft base; the conductive block is connected on the crankshaft; the electromagnet is fixedly arranged on the conductive block; the permanent magnet is fixedly arranged on the cutting knife; and a return spring is connected between the cutting knife and the rack. The invention provides the cutting device used for the refrigerator water channel rubber ring, and the cutting device can reduce labor intensity of staff, and reduces labor cost.

Description

technical field [0001] The invention relates to a cutting device, in particular to a cutting device for a refrigerator water channel rubber ring. Background technique [0002] In the prior art, the freezer-refrigeration conversion refrigerator can meet the different needs of users in different seasons, and can switch between freezing and refrigeration at will; when the freezer is converted into a refrigerator, the frost on the evaporator will melt into water, so in order to To discharge water, it is necessary to set up a water delivery pipe under the evaporator, and a drain pipe on the body. The water melted from the evaporator will enter the drainage pipe through the water delivery pipe and be discharged outside the body; During the process, in order to prevent water from leaking through the connection between the water delivery pipe and the drainage pipe, when the water delivery pipe and the drainage pipe are connected, a rubber sealing ring will be added between the two t...

Problems solved by technology

[0004] For the above steps, the cutting step is more important, and the cutting efficiency directly affects the yield of the apron. In order to solve the above problems, there is a cutting device in the prior art, which includes a cutting knife, a cylinder, a cutting seat, a cylinder output rod and a cutting The tops of the knives are connected, and the cutting seat is set directly below the cutting knife; during specific operations, the operator puts the rubber hose on the cutting seat, and then uses the cylinder to control the downward movement of the cutting knife and cuts the rubber hose; The knife is reset, because the cut part of the rubber hose becomes a gasket, so when the cutting knife descends again, the cutting knife cannot cut the shortened rubber hose, and the operator needs to adjust the position of the rubber hose to the position that needs to be cut

[0005] Although the efficiency of the above cutting devices has been improved, there are still certain problems: 1. Using the cylinder to control the reciprocating movement of the cutting knife requires the operator to control each direction change, which not only increases the operating steps, but also increases the operator's work. Labor intensity; 2. Every time the rubber hose is cut, the operator needs to control the position of the rubber hose, which also increases the operation steps and increases the labor intensity of the personnel. Moreover, the thickness of each gasket cannot be guaranteed, which increases the amount of defective products obtained. , higher manufacturing cost
