Description

Technical Field

[0001] The invention belongs to the technical field of bread production, and in particular refers to packaging equipment for bread production and processing. Background Art

[0002] Bread is made from rye, wheat and other grain crops as basic raw materials. After processing them into powder, other auxiliary materials are added and kneaded into dough, which is then heated by baking, roasting, steaming, frying, etc. to make fluffy food. After the bread is produced and formed, it needs to be packaged. At present, bread packaging is done automatically by packaging machines.

[0003] The preservation of bread requires filling the packaging with inert gas to prevent the bread from oxidation and deterioration, thereby extending the shelf life of the bread. Before filling the inert gas, the air inside the packaging bag needs to be exhausted. Existing packaging machines mostly use exhaust equipment to exhaust the air inside the packaging bag, but the exhaust force is difficult to control, which can easily cause the bread to be compressed and deformed, affecting the appearance of the bread.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows: 1. By blowing air into the packaging bag, the air inside the packaging bag is squeezed out without causing damage to the bread inside the packaging bag, thus achieving lossless exhaust.

[0017] 2. The forward-pushing air blowing assembly and the high-pressure non-return air blowing assembly are driven by the translation mechanism to move from the rear end of the packaging bag to the front end (opening end) of the packaging bag, thereby squeezing out the air in the packaging bag from the back to the front. When the translation mechanism drives the forward-pushing air blowing assembly to move, the follower gear and the fixed rack move relative to each other, and the follower gear drives the rotating drum to rotate through the ventilation pipe, so that the rotating drum moves and rotates at the same time. The rotating drum that continuously rotates toward the direction of the inflation and heat sealing mechanism drives the high-pressure airflow to blow from the back to the front, thereby discharging the air inside the packaging bag from the opening end.

[0018] 3. The gas flow rates of the forward-push blowing assembly and the high-pressure non-return blowing assembly are different, so the blowing force of the airflow on the packaging bag is different. The blowing force generated by the high-pressure non-return blowing assembly is greater than the blowing force of the forward-push blowing assembly, which can effectively prevent the air in the packaging bag from moving backward. At the same time, the high-pressure non-return blowing assembly can also further discharge the packaging bag for flexible squeezing, so as to discharge the air in the packaging bag to the greatest extent.

[0019] 4. The opening of the packaging bag can be sealed and clamped by the clamping spring and the sliding plate in cooperation with the fixed plate, which is convenient for inflating the packaging bag. At the same time, when the air nozzle is pulled out, the clamping spring automatically pushes the sliding plate to align with the fixed plate, thereby facilitating the sealing, clamping and heat sealing of the opening of the packaging bag.

[0020] 5. The push plate and the fixed baffle can be pre-adjusted according to the size of the packaging bag, so that the opening of the packaging bag is always in contact with the side wall of the fixed baffle, thereby facilitating the inflation and heat sealing of packaging bags of different sizes.

[0039] The motor 38 is electrically connected to an intermittent operation control circuit, see Fig.13The intermittent operation control circuit consists of a power supply QS, a switch S, a key button SB1, a key button SB2, a fuse FU1, a fuse FU2, a thermal relay FR, an AC contactor KM, a time relay KT1, a time relay KT2, an intermediate relay KA and a motor M (i.e., motor 38). The AC contactor KM is used to control the start and stop of the motor M. The time relay KT1 and the time relay KT2 are used to realize the intermittent operation of the motor M. The intermediate relay KA serves as an intermediate link to cut off the power supply of the motor M after the delayed closing contact of the time relay KT1 is closed, thereby stopping the motor M.

[0040] The working principle of the intermittent operation control circuit is as follows: when the switch S is closed, the key button SB1 is closed, the AC contactor KM and the time relay KT1 are energized and attracted, and the motor M starts to run. At the same time, the time relay KT1 starts timing. When the timing time of the time relay KT1 reaches the set value, the delayed closing contact of the time relay KT1 is closed, so that the coil of the intermediate relay KA is energized, and the normally closed contact of the intermediate relay KA is disconnected, and the normally open contact is closed. The normally closed contact of the intermediate relay KA is disconnected, so that the coil of the AC contactor KM is de-energized, the main contact is disconnected, and the motor stops running; the intermediate The normally open contact of relay KA is closed to energize the coil of time relay KT2 and start timing. When the timing time of time relay KT2 reaches the set value, the delayed disconnect contact of time relay KT2 is disconnected, the intermediate relay KA and the coil of time relay KT2 lose power, the normally closed contact of intermediate relay KA is reset, the coil of AC contactor KM is energized, and motor M starts to run. The continuous cycle realizes intermittent operation control. The function of time relay KT1 in the circuit is to control the running time, and the function of time relay KT2 is to control the stop time. When motor M stops working, just disconnect the key button SB1.

[0041] During specific use, the intermittent operation control circuit drives the motor 38 to rotate intermittently periodically, and the transmission shaft 36 drives the conveyor belt 37 to transmit intermittently periodically. Each rotation of the motor 38 drives the partition 39 to rotate from the current position to the next partition 39, and the packaging bag with bread and one side open is placed on the conveyor belt 37, with the opening of the packaging bag facing the fixed baffle 34, and one is placed between two adjacent partitions 39. The inclined processing table 2 makes the bread drive the bottom end of the packaging bag to fit with the adjustment push plate 33. At this time, the adjustment electric cylinder 32 is started to drive the adjustment push plate 33 to move, and the adjustment push plate 33 drives the packaging bag and bread to move, so that the opening side of the packaging bag is close to the fixed baffle 34. When the opening side of the packaging bag fits with the fixed baffle 34, the control adjustment electric cylinder 32 is stopped. To stop the elongation, the subsequent staff will place the packaging bag in the storage space surrounded by the partition 39, the adjustment push plate 33 and the fixed baffle 34. When there is bread between the reflective photoelectric switch 70 on the side wall of the adjustment push plate 33 and the air nozzle 42, and the motor 38 is in a stopped state, the packaging bag containing bread is transmitted to the partitioned lossless exhaust mechanism 7. The reflective photoelectric switch 70 detects the obstacle and sends a signal to the controller 68. The controller controls the partitioned lossless exhaust mechanism 7 and the inflation heat sealing mechanism 6 to operate within the stop time of the motor 38. In the initial state, the forward push blowing assembly 11 and the high-pressure non-return blowing assembly 12 are located on the side of the conveyor belt 37 away from the inflation heat sealing mechanism 6, the second electric push rod 46 is in a retracted state, and the air nozzle 42 is away from the conveyor belt 37, the controller 68 controls the second electric push rod 46 to extend, and controls the inflation solenoid valve 52 to close, and controls the exhaust solenoid valve 50 to open, the second electric push rod 46 pushes the inflation chamber 47 to move closer to the conveyor belt 37, and the inflation chamber 47 drives the air nozzle 42 to move and insert into the packaging bag, and then the controller 68 controls the clamping motor 58 to start, the clamping motor 58 moves towards each other through the two groups of clamping plates 57 symmetrically arranged at the bottom end of the bidirectional screw 55 and clamps the packaging bag between the clamping plates 57 and the air nozzle 42, when the clamping plates 57 move towards each other and fit together, the air nozzle 42 pushes the sliding plate 63 to drive the cross plate 65 to move along the clamping sliding shaft 64, so as to avoid the air nozzle 42, and then the controller 68 starts the translation motor 24 and the high-pressure air pump 9, the high-pressure air pump 9 High-pressure airflow is introduced into the forward-pushing blowing assembly 11 and the high-pressure non-return blowing assembly 12 through the pipeline, and the translation motor 24 drives the translation screw 26 to rotate. The translation screw 26 drives the translation slide 13 to move along the translation screw 26 and the limit slide 25 through the translation slider 27. The translation slide 13 drives the forward-pushing blowing assembly 11 and the high-pressure non-return blowing assembly 12 from the closed side of the packaging bag to the open side of the packaging bag. When the translation slide 13 moves, it drives the fixed cylinder 14, the rotating cylinder 15 and the follower gear 16 to move synchronously, and the fixed rack 17 remains stationary, so that the follower gear 16 and the fixed rack 17 produce relative movement, so that the follower gear 16 rotates, and the follower gear 16 drives the rotating cylinder 15 to rotate through the ventilation pipe 20. During the rotation of the rotating cylinder 15,The high-pressure airflow is discharged through the blowing holes 18 exposed at the arc-shaped through holes 19 and blown toward the packaging bag. When the forward-pushing blowing assembly 11 and the high-pressure non-return blowing assembly 12 move, the forward-pushing blowing assembly 11 first blows air into the packaging bag, so that the gas in the packaging bag is squeezed out under the action of the blowing force, and the high-pressure non-return blowing assembly 12 then blows air into the packaging bag for the second time. The cross-sectional area of ​​the concentrated air nozzle 22 gradually decreases from top to bottom. By reducing the cross-sectional area of ​​the concentrated air nozzle 22, the gas flow speed is increased, the blowing force is increased, and the blowing force of the airflow blown out by the high-pressure non-return blowing assembly 12 is increased. The blowing force of the airflow blown out by the forward-pushing blowing assembly 11 is greater than that by the rotating drum 15 which continuously rotates toward the inflation heat sealing mechanism 6, so that the gas in the packaging bag can be completely squeezed out without causing damage to the bread. When the translation slide 13 moves to the end of the translation screw 26, the controller 68 controls the high-pressure air pump 9 to stop working and controls the translation motor 24 to reverse. The translation motor 24 reverses and drives the forward-pushing blowing assembly 11 and the high-pressure non-return blowing assembly 12 to move in the opposite direction and reset through the translation screw 26. At the same time, the controller 68 controls the inflation solenoid valve 52 to open and controls the exhaust solenoid valve 52 to open. The valve 50 is closed, and then the controller 68 controls the air pump 45 to work. The air pump 45 delivers the inert gas in the gas storage tank 44 into the air filling chamber 47 through the air filling pipe 53, and then fills the packaging bag through the air nozzle 42. The fixed plate 62 and the sliding plate 63 clamp and seal the opening of the packaging bag to prevent gas leakage. The air pressure sensor 48 detects the air pressure in the packaging bag in real time. When the air pressure reaches the preset value, the air pressure sensor 48 triggers the controller 68 to control the air pump 45 to stop working, and controls the second electric push rod 46 to contract to drive the air nozzle 42 to be drawn out of the packaging bag. Then the controller 68 controls The heating plate 61 heat-seals the open side of the packaging bag. After the air nozzle 42 is pulled out, the clamping spring 67 pushes the horizontal plate 65 to drive the sliding plate 63 to insert into the avoidance hole. At this time, the sliding plate 63 is aligned with the fixed plate 62 so that the open side of the packaging bag is completely pressed and heat-sealed. After a certain period of heat sealing, the controller 68 controls the heating plate 61 to stop working and controls the clamping motor 58 to drive the bidirectional screw 55 to reverse. The bidirectional screw 55 drives the symmetrically arranged clamping plates 57 to separate, releasing the packaging bag after inflation and heat sealing. Then the motor 38 rotates again, and the above operation is repeated to inflate and heat-seal the next packaging bag.
