Description

TECHNICAL FIELD

[0001] The present application relates to the field of automatic packaging, in particular to a flattening machine. BACKGROUND

[0002] When packing fan bones in a food processing factory, the fan bones are first put into bags and sealed, then a vacuum pump is used to perform vacuum treatment on the packaging bag, and then the packaged fan bones are transported to the flattening machine for flattening the fan bones and the packaging bag, facilitating boxing and packaging.

[0003] Because the bone part of the fan bone is hard, part of the bone residue may adhere to the fan bone during cutting. If the bone residue adheres to the bone part of the fan bone, the protrusion of the bone residue part may pierce the packaging of the fan bone when the fan bone is flattened after being packaged, resulting in packaging damage. If the packaging is damaged, microorganisms enter the packaging bag from the damage, causing the fan bone to rot, thereby affecting the quality of the product. CONTENT OF THE INVENTION

[0004] In order to reduce the possibility of the flattening machine damaging the packaging of the fan bone, the present application provides a flattening machine.

[0005] The flattening machine provided by the present application adopts the following technical solution:

[0006] A flattening machine, comprising a rack and a pressing plate, the pressing plate being movable up and down, the pressing plate and the rack being arranged in parallel, a gas bag being arranged on the pressing plate, a connecting structure being arranged between the gas bag and the pressing plate; the connecting structure comprising a connecting pin and a connecting sheet, a connecting hole one being arranged on the gas bag, a connecting hole two being arranged on the pressing plate, the connecting pin being provided with a limiting sheet at one end, a threaded hole being formed in the connecting sheet, the connecting pin being threadedly connected to the threaded hole while penetrating the connecting hole one and the connecting hole two.

[0007] By adopting the above technical solution, when the fan bone and the packaging are flattened, the pressing plate is pressed downward to flatten the fan bone and the packaging. Because the bone residue may pierce the packaging and affect the quality of the fan bone, a gas bag is arranged, which is concave inward when the bone residue is extruded, thereby reducing the possibility of the bone residue piercing the packaging.

[0008] The gas bag may be aged after long-term use, and the aged gas bag may be pierced by a sharp corner during flattening, causing a safety hazard. Therefore, the connecting structure is arranged to facilitate replacement of the gas bag; when replacing the gas bag, the connecting pin is rotated out of the connecting sheet to release the limitation of the connecting pin on the connecting sheet, and after replacing the gas bag, the connecting pin is simultaneously penetrated through the pressing plate and the gas bag, and the connecting pin is rotated into the connecting sheet to fix the gas bag on the bottom surface of the pressing plate.

[0009] Optionally, a driving member is arranged on the rack to drive the pressing plate to move up and down.

[0010] By adopting the above technical scheme, the driving member is arranged to facilitate driving the pressing plate to move and flatten the fan bones.

[0011] Optionally, the driving member comprises a pneumatic cylinder fixedly connected to the rack, and a piston rod of the pneumatic cylinder is fixedly connected to the pressing plate.

[0012] By adopting the above technical scheme, when the pressing plate is driven to move, the piston rod of the pneumatic cylinder moves downward to drive the pressing plate to move downward and flatten the fan bones; the pneumatic cylinder is selected as the driving member, the moving distance of the pressing plate can be controlled by controlling the air intake and exhaust amount, and different thicknesses of the fan bones can be flattened.

[0013] Optionally, the rack comprises a moving part and a supporting part, the supporting part is swingably connected to the moving part, and an adjusting structure for adjusting the angle of the supporting part is arranged between the moving part and the supporting part.

[0014] By adopting the above technical scheme, in actual production process, the angle of the supporting part can be adjusted to adjust the angle of the conveying belt, so that the conveying belt is downwardly inclined to facilitate unloading or upwardly inclined to facilitate loading, and the adjusting structure is arranged to facilitate adjusting the angle of the supporting part.

[0015] Optionally, the adjusting structure comprises a driving gear, a driven gear, and a motor for driving the driving gear to rotate, the driving gear is rotatably connected to the moving part, the driven gear is fixedly connected to the supporting part, and the rotation axis of the driven gear and the rotation axis of the supporting part overlap.

[0016] By adopting the above technical scheme, when the angle of the supporting part is adjusted, the motor drives the driving gear to rotate to drive the driven gear to rotate, and the supporting part rotates accordingly, so that the supporting part is adjusted to an appropriate angle, which is simple in structure and convenient to operate.

[0017] Optionally, the radius of the driving gear is smaller than the radius of the driven gear.

[0018] By adopting the above technical scheme, the radius of the driving gear is smaller than the radius of the driven gear, the driving gear rotates for multiple turns, and the driven gear rotates for one turn, so that the effect of deceleration is achieved and the stability during adjusting the angle of the supporting part is improved.

[0019] Optionally, a conveying belt for conveying the fan bones is arranged on the rack.

[0020] By adopting the above technical scheme, the conveying belt is arranged to facilitate flattening the fan bones without manually putting the fan bones into the rack one by one, and the production line is improved in efficiency.

[0021] Optionally, a baffle is arranged on the rack, and the baffle is arranged perpendicularly to the rack and along the conveying direction of the transmission belt.

[0022] By adopting the above technical scheme, the baffle can reduce the possibility of fan bones falling from the rack.

[0023] In summary, the present application has the following beneficial technical effects:

[0024] 1. By arranging the air bag, the air bag can be concave inward when the air bag extrudes bone residue, so as to reduce the possibility of the bone residue piercing the package;

[0025] 2. By arranging the connecting structure, the air bag can be replaced, and the possibility of the aged air bag being pierced by the bone residue in production is reduced. BRIEF DESCRIPTION OF DRAWINGS
