Description

Technical Field

[0001] The present invention relates to the technical field of food processing, and particularly to a safe automatic bone sawing machine. Background Art

[0002] A bone sawing machine is a processing device for various medium and small animal bones, frozen meat, fish with bones, and frozen fish. A bone sawing machine generally consists of a frame, a motor, a circular saw, a translation table, and an electric control working board.

[0003] Patent document CN113180089B, a raw meat bone sawing machine for supermarkets, includes a frame and an upper pulley and a lower pulley rotatably connected to the frame. A saw blade in a ring structure is sleeved on the upper pulley and the lower pulley. A driving device for driving the lower pulley to rotate is installed on the frame. An installation table located between the upper pulley and the lower pulley is also fixed on the frame. The saw blade includes two oppositely arranged saw teeth. The installation table includes a working table located outside the saw blade and a blanking table located inside the saw blade. The patent document improves the production efficiency of cutting.

[0004] Since most bone sawing machines are for greasy foods, cutting will cause the grease to melt on the working board. During the process of manually operating the bone sawing machine, the limbs need to be close to the high-speed rotating electric saw blade. Most of the time, the rotating door needs to be fixed completely before using the pushing shell to abut against the bone to achieve bone sawing. Therefore, the closed installation of the rotating door is one of the necessary conditions for the safe use of the bone sawing machine. There is no safety structure for the closing of the rotating door in the prior art to achieve the safe use of the machine. It can still be used in the state where the rotating door is not closed. Therefore, most of the bone sawing machines on the market have a low safety factor, and workers are extremely prone to work-related injury accidents during cutting operations. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that in a greasy environment, there is no safety structure for the rotating door to forcibly drive the start and closing of the motor to standardize the safe operation of users.

[0006] The present invention is a safe automatic bone sawing machine, including a frame. An inner groove is provided inside the frame and a cutting mechanism is installed. A rotating door is installed on one side of the frame, and a safety structure is installed at the bottom of the rotating door.

[0007] The safety structure includes a connecting column and a fixed sleeve. The connecting column is installed at the bottom of the revolving door, and the fixed sleeve is installed at the bottom of the frame. One end of the fixed sleeve is a large-head end and is located on the side of the frame opposite to the revolving door. An external thread portion is installed on the fixed sleeve and connected to the frame, extending to the other side of the frame and locked by installing a nut. An elastic member is installed inside the fixed sleeve. The bottom of the frame includes a bottom plate, and a long-axis type microswitch is installed on the bottom plate. One end of the elastic member is adapted to abut against the moving arm of the long-axis type microswitch and trigger the long-axis type microswitch when the other end is squeezed by the connecting column.

[0008] A driving motor is installed on the bottom plate. The driving motor is adapted to drive the cutting mechanism to rotate. A touch switch is installed outside the frame. The driving motor works when both the touch switch and the long-axis type microswitch are closed. In a further technical solution, a large-diameter hole is provided inside the fixed sleeve, and one end of the large-diameter hole away from the connecting column is a small-diameter hole, and the aperture of the small-diameter hole is smaller than that of the large-diameter hole.

[0009] A moving column is installed inside the large-diameter hole. Connecting pieces one and two are respectively installed at both ends of the moving column. A return spring is installed on the moving column of the connecting piece one. One end of the return spring is adapted to abut against the connecting piece one, and the other end of the return spring is adapted to abut against the small-diameter hole two. The connecting piece two is adapted to abut against the moving arm of the long-axis type microswitch.

[0010] The outer diameter of the connecting piece one is smaller than the aperture of the large-diameter hole, and the outer diameter of the connecting piece two is larger than the aperture of the small-diameter hole.

[0011] Specifically, by installing a connecting column at the bottom of the revolving door and squeezing the elastic member inside the fixed sleeve after closing, the closing abutment is transmitted to the long-axis type microswitch to achieve signal transmission. During use, the driving motor drives the saw blade to rotate only when both the long-axis type microswitch and the touch switch are pressed. If any one of the switches is disconnected, the driving motor cannot work. This can achieve safe operation in the closed and locked state of the revolving door, facilitate the standardized operation of the operator, and avoid the occurrence of safety accidents caused by the revolving push shell when the revolving door is in the open state.

[0012] In a further technical solution, a working plate is installed on the frame, and a processing groove is provided on the working plate. The cutting mechanism includes an upper runner and a lower runner. The lower runner is coaxially connected to the output shaft of the driving motor. A saw blade is connected between the upper runner and the lower runner, and the saw blade is adapted to pass through the processing groove.

[0013] The driving method adopts the installation method of upper and lower wheels, and the flexible saw blade can rotate reciprocally between the two wheels.

[0014] In a further technical solution, one side of the rotating door is hinged to the frame, a fixed column is arranged on the other side of the rotating door, a clamping knob is installed on the frame, the clamping knob is connected to the frame and is provided with a curve groove inside, and the curve groove is adapted to clamp the fixed column.

[0015] After the clamping knob rotates, the rotating door effectively closes and clamps the clamping column and the fixed column to achieve the closing effect.

[0016] In a further technical solution, an extension frame is installed on the working plate. The extension frame is in a "C" shape and both ends are fixed to the working plate. A sliding block is installed inside the extension frame. The sliding block slides on the extension frame and a locking knob is installed at the top. The locking knob is adapted to lock the sliding block on the extension frame;

[0017] A limiting plate is installed between the locking knob and the sliding block. The limiting plate is a bent plate. The limiting plate is adapted to be installed on the working plate, and the length of the limiting plate is adapted to the length of the processing groove.

[0018] The position of the limiting plate on the working plate can be adjusted to achieve the effect of cutting bones of different sizes.

[0019] In a further technical solution, a measuring range is marked on the working plate and is located at the bottom of the limiting plate.

[0020] In a further technical solution, a pushing shell is rotatably installed at the bottom of the rotating door. The pushing shell is in an "L" shape. The pushing shell is adapted to be installed outside the saw blade on the working plate, and a fixed handle is installed on the side of the pushing shell facing away from the saw blade.

[0021] In a further technical solution, a limiting column is installed in the inner groove. The limiting column is adapted to rotate in the inner groove, and a connecting plate is installed on the limiting column. The connecting plate is adapted to limit the rotation of the saw blade.

[0022] In a further technical solution, a material collection box is installed at the bottom of the bottom plate. The material collection box is detachably connected to the bottom plate.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] For the existing bone sawing machine of the present invention, there is no effective protection for the safe closing at the rotating door. When the operator does not close the rotating door properly, it will cause friction between the rotating position of the pushing shell and the saw blade. Manually pushing the bone will cause violent changes due to friction and accidents will occur. Therefore, the closing of the rotating door is very necessary for the operator.

[0025] In the present invention, through an interlocking method, the rotation of the drive motor can only be achieved when the touch switch and the micro switch are both closed. The touch switch is manually pressed, and the micro switch can effectively work only when the revolving door is manually closed and locked, achieving the effect of safe operation.

[0026] In the present invention, a movable limit plate is installed to achieve the bone forming effect of various sizes; a clamping knob is used to cooperate with a fixed column to achieve quick closing; a connecting plate and a limit column are used to achieve the rotation of the saw blade of the aligner.
