Problems solved by technology

The Chinese invention patent once disclosed a technical solution called "Safety Electric Meat Grinder" (Patent No.: z1200610035915.1). Photoelectric safety protection switch, when the hand reaches into the feeding barrel, the photoelectric safety protection switch will act, cut off the power of the drive device, and prevent the hand from being twisted by the screw. This structural design effectively improves the safety performance of the meat grinder. However, this This kind of meat grinder only solves the safety problem at the feeding barrel, and there has been no relevant protection measures for the safety protection of the most dangerous blade position.
The blades in the meat grinding part of the existing meat grinder are generally directly socketed on the propulsion screw and driven by an electric motor. For this type of meat grinder, when changing the blade or cleaning the blade, when the cover is opened, The blade may still be rotating, or the switch of the motor may be touched by mistake, and the blade will rotate suddenly, which will easily hurt people and cause a great safety hazard

Embodiment 1

[0016] Example one: such as figure 1 , figure 2 As shown, the meat grinder of the present invention includes a barrel 1 with a feed port 11, a propelling screw 2, a blade 3, a screw cap 4 with a discharge port 41, a discharging screen 5 and a gear drive Part 6, the blade 3 is fixed on the top of the pushing screw 2, the discharging screen 5 is fixedly installed on the barrel 1 through the screw cap 4. The lower end of the pushing screw 2 is driven by the motor 8 through the gear transmission part 6, and is under the barrel 1. A micro switch 7 that can control the action of the motor 8 is installed on the body. A pressing protrusion 50 is provided on the outside of the discharging screen 5. The transmission mechanism 9 is mainly composed of a connecting push rod 91 and a compression spring 92 looped on the connecting push rod 91. And the fixed screw 93 is formed with a connecting push rod through hole in the center of the fixed screw 93, a channel for the connecting push rod 91 t...

Embodiment 2

[0017] Embodiment two: such as image 3 , Figure 4 As shown, the main structure is basically the same as that of the first embodiment. The difference is that the control structure of the discharging screen 5 is a convex shaft 51 arranged on the lower end surface. The convex shaft 51 is inserted into the upper end of the channel of the barrel 1, and the convex The shaft 51 drives the micro switch 7 through the transmission mechanism 9 to make it in a closed state.

Abstract

The invention relates to a meat grinder which comprises a cylinder body provided with a charging port, a propelling screw rod, a blade, a discharging meshed plate, a rotating cover with a discharging port, a motor and a gear drive part driven by the motor, wherein, the propelling screw rod, the blade and the discharging meshed plate are installed in the cylinder body in sequence and fixedly installed on the cylinder body through the rotating cover; and the lower end of the propelling screw rod is driven by the gear drive part. The meat grinder is characterized in that: a safety device which can prevent the motor from starting is installed on the meat grinder and the safety device comprises a micro switch which is arranged on the machine body under the cylinder body and can control the action of the motor, a transmission mechanism arranged on the cylinder body and a control structure arranged on the discharging meshed plate, wherein, the control structure controls the on / off of the micro switch through the transmission mechanism. The meat grinder adopting the structure can prevent the blade from hurting people, thus being safe and reliable.

Description

Technical field [0001] The invention belongs to the field of food processing machinery manufacturing, and specifically relates to a meat grinder. Background technique [0002] The current meat grinder that uses a motor to drive the screw and blades generally only has a main switch to control the operation of the motor of the meat grinder, and lacks a linkage safety protection device. The meat grinder with this structure may cause the user to operate the meat grinder due to incorrect operation. Accidents injuring people by pushing screws or blades happen from time to time. The Chinese invention patent once disclosed a technical solution called "safe electric meat grinder" (Patent No.: z1200610035915.1). The meat grinder disclosed in this technical solution has an electrical connection with the drive device on the feeding cylinder Photoelectric safety protection switch. When the hand reaches into the feeding barrel, the photoelectric safety protection switch acts to cut off the pow...
