Description

Technical Field

[0001] This invention relates to the field of vacuum packaging technology, specifically to a vacuum packaging device and method for imitation silk cotton rolls. Background Technology

[0002] Vacuum packaging equipment is a device used to seal food or other items in a vacuum environment. The principle of vacuum packaging is to remove the air from the inside of the packaging bag, thereby reducing the oxygen concentration inside the bag and extending the shelf life of the food. Vacuum packaging equipment typically includes components such as a vacuum pump, a sealer, and a control system. It can be widely used in food processing, pharmaceutical manufacturing, and electronic products.

[0003] Chinese patent CN213008917U discloses a vacuum packaging device for glass wool rolls, including two slide rails. Four sets of rollers are symmetrically arranged in the slide grooves of the slide rails. Each set of rollers has a lead screw nut at the lower end of the connecting rod. The lead screw nuts of the two sets of rollers on the same side are sleeved on the lead screw. The upper ends of the rollers are symmetrically arranged at the lower end of the pre-compression box through fixing blocks. A through groove is opened on one side of the box plate of the pre-compression box, and a bag opening plate is provided on one side of the lower end of the through groove. The upper ends of the other three side boxes of the pre-compression box are provided with inwardly inclined guide plates.

[0024] To better achieve the objectives of this invention, the present invention also provides a method for using a vacuum packaging device for imitation silk cotton rolls, comprising the following steps:

[0025] Step 1: The external bag feeding mechanism places the bag onto the second conveyor belt, which drives the bag to move to below the bag opening and supporting assembly; the supporting assembly is activated to open the bag opening below, and the opening mechanism is activated to open the bag opening, thus completing the bag opening.

[0026] Step Two: The first conveyor belt transports the imitation silk cotton roll to the arc-shaped bracket. The linear module is activated, and the linear module drives the fixed plate to move to the left under the action of the linear guide rail, the first slide groove, the first cam bearing follower, the connector, and the rotating shaft. The rotating shaft drives the housing to move to the left, and the housing drives the clamping roller to move to the left and insert it into the clearance groove. The first motor is activated, and the first motor drives the gear to rotate. The gear drives the gear ring to rotate, and the gear ring drives the ring to rotate. The ring drives the slider to move inward along the second slide groove under the combined action of the arc-shaped groove and the clamping roller. The clamping roller moves inward to clamp the imitation silk cotton roll. The linear module is activated, and the linear module drives the fixed plate to move to the right and rotate 180 degrees under the action of the linear guide rail, the first slide groove, the first cam bearing follower, the connector, and the rotating shaft. The rotating shaft drives the housing to move to the right and rotate 180 degrees, and the housing drives the clamping roller to move to the right and rotate 180 degrees. The end of the clamping roller away from the housing is inserted into the bag. The first cylinder is activated, and the first cylinder drives the push block to move to the right to push the imitation silk cotton roll into the bag.

[0027] Step 3: Start the second cylinder. The second cylinder moves the mounting box downward to press down the imitation silk cotton roll. Start the second motor. The second motor drives the bidirectional threaded rod to rotate. The bidirectional threaded rod drives the clamping block to move inward to clamp the imitation silk cotton roll.

[0028] Step 4: Start the linear module and the first motor. The linear module drives the fixed plate to move to the left and rotate 180 degrees under the action of the linear guide rail, the first slide groove, the first cam bearing follower, the connector and the rotating shaft. The rotating shaft drives the housing and the clamping roller to move to the left and rotate 180 degrees to reset. Then the first motor drives the gear to rotate, the gear drives the gear ring to rotate, the gear ring drives the ring to rotate, and the ring drives the slider to move outward along the second slide groove to reset under the combined action of the arc groove and the clamping roller.

[0029] Step 5: Start the third motor. The third motor drives the threaded rod to rotate. The threaded rod drives the moving block to slide to the right under the action of the first slide rod. The moving block drives the mounting block to move diagonally upward and then to the right under the combined action of the second slide rod, the second cam bearing follower, and the third slide groove. The mounting block drives the vacuum pump to move. The vacuum pump drives the connecting pipe to move, extending the right end of the connecting pipe into the bag. The electric cylinder drives the connecting block to move downward. The connecting block drives the heat sealing plate to move downward.

Start the vacuum pump to evacuate the bag. Start the third motor. The third motor drives the threaded rod to rotate. The threaded rod drives the moving block to slide to the left under the action of the first slide rod. The moving block drives the mounting block to move to the left and then diagonally downward under the combined action of the second slide rod, the second cam bearing follower, and the third slide groove. The mounting block drives the vacuum pump to move. The vacuum pump drives the connecting pipe to move, pulling the right end of the connecting pipe out of the bag opening and resetting it.

[0030] Step Six: The electric cylinder drives the connecting block to move downwards, which in turn drives the heat-sealing plate to move downwards. The heat-sealing plate then drives the limiting block and the sealing block to move downwards. The sealing block drives the sliding rod to slide upwards in the groove at the lower end of the sleeve to compress the spring until the lower end of the limiting block presses down on the bag to heat-seal the bag opening. After heat sealing, the heat-sealing plate and the sealing block reset, and the second cylinder drives the mounting box and the clamping block to reset. The sealed bag is then conveyed to the unloading end by the second conveyor belt, completing the vacuum packaging of the imitation silk cotton roll.

[0031] The present invention has the following technical effects:

[0032] The external bag feeding mechanism of this invention places the bag on the second conveyor belt. The second conveyor belt drives the bag to move to the bottom of the bag opening and supporting assembly. The bag opening and supporting assembly opens the bag. At the same time, the first conveyor belt conveys the imitation silk cotton roll to the arc-shaped bracket.

The rotating shaft drives the housing to move to the left, and the housing drives the clamping roller to move to the left and insert it into the clearance groove. The first motor is then activated, driving the gear to rotate. The gear drives the gear ring to rotate, and the gear ring drives the circular ring to rotate. The circular ring drives the slider to move inward along the second slide groove under the combined action of the arc-shaped groove and the clamping roller. The clamping roller moves inward to clamp the imitation silk cotton roll. The linear module is then activated again. The linear module drives the fixed plate to move to the right and rotate 180 degrees under the action of the linear guide rail, the first slide groove, the first cam bearing follower, the connector, and the rotating shaft. The rotating shaft... The housing moves to the right and rotates 180 degrees. The housing moves the clamping roller to the right and rotates 180 degrees. The end of the clamping roller away from the housing is inserted into the bag. The first cylinder is activated. The first cylinder moves the push block to the right and pushes the imitation silk cotton roll into the bag. The bag-blocking assembly clamps the imitation silk cotton roll. The linear module and the first motor are activated.

The rotating shaft moves the housing and the clamping roller to the left and rotates 180 degrees to reset. Then the first motor drives the gear to rotate. The gear drives the gear ring to rotate. The gear ring drives the ring to rotate. The ring drives the slider to move outward along the second slide groove under the combined action of the arc groove and the clamping roller to reset.

[0034] When opening the bag in this invention, the bag-supporting mechanism is activated to open the bag opening that has been transported to the bottom, and the bag-opening mechanism is activated to open the bag opening to complete the opening of the bag;

[0035] When the imitation silk cotton roll is put into the bag, the second cylinder is activated, which drives the mounting box to move downward to press the imitation silk cotton roll. The second motor is activated, which drives the bidirectional threaded rod to rotate. The bidirectional threaded rod drives the clamping block to move inward to clamp the imitation silk cotton roll.

[0036] During vacuuming, the third motor is started, which drives the threaded rod to rotate. The threaded rod drives the moving block to slide to the right under the action of the first slide rod. The moving block drives the mounting block to move obliquely upward and then to the right under the combined action of the second slide rod, the second cam bearing follower, and the third slide groove. The mounting block drives the vacuum pump to move, and the vacuum pump drives the connecting pipe to move so that the right end of the connecting pipe is inserted into the bag. After the bag sealing assembly presses the bag opening, the vacuum pump is started to vacuum the bag. Finally, the third motor is started, which drives the threaded rod to rotate. The threaded rod drives the moving block to slide to the left under the action of the first slide rod. The moving block drives the mounting block to move to the left and then to obliquely downward under the combined action of the second slide rod, the second cam bearing follower, and the third slide groove. The mounting block drives the vacuum pump to move, and the vacuum pump drives the connecting pipe to move so that the right end of the connecting pipe is pulled out of the bag opening and reset. The bag sealing assembly then heat seals the bag opening.

[0037] When sealing the bag in this invention, the electric cylinder drives the connecting block to move downwards, the connecting block drives the heat sealing plate to move downwards, the heat sealing plate drives the limiting block and the sealing block to move downwards until the sealing block presses down on the bag opening and the semi-circular groove presses down on the connecting tube. After the connecting tube is pulled out of the bag opening, the electric cylinder continues to drive the connecting block to move downwards, the connecting block drives the heat sealing plate to move downwards, the heat sealing plate drives the limiting block and the sealing block to move downwards, and the sealing block drives the sliding rod to slide upwards in the sliding groove at the lower end of the sleeve to compress the spring until the lower end of the limiting block presses down on the bag to heat seal the bag opening. After heat sealing, the heat sealing plate and the sealing block reset, the second cylinder drives the mounting box and the clamping block to reset, and the sealed bag is conveyed to the unloading end by the second conveyor belt to complete the vacuum packaging of the imitation silk cotton roll.

The heat sealing plate (73) drives the limit block (74) and The sealing block (75) moves downward until the sealing block (75) presses against the bag opening and the semi-circular groove (76) presses against the connecting pipe (611). The vacuum pump (610) is started to evacuate the bag. The third motor (62) is started. The third motor (62) drives the threaded rod (63) to rotate. The threaded rod (63) drives the moving block (65) to slide to the left under the action of the first slide rod (64). The moving block (65) drives the mounting block (67) to move to the left and then to the lower side under the combined action of the second slide rod (66), the second cam bearing follower (68) and the third slide groove (69). The mounting block (67) drives the vacuum pump (610) to move. The vacuum pump (610) drives the connecting pipe (611) to move and pull the right end of the connecting pipe (611) out of the bag opening and reset it. Step 6: The electric cylinder (71) drives the connecting block (72) to move downward, the connecting block (72) drives the heat sealing plate (73) to move downward, the heat sealing plate (73) drives the limiting block (74) and the sealing block (75) to move downward, the sealing block (75) drives the slide rod (78) to slide upward in the groove at the lower end of the sleeve (77) to compress the spring (79) until the lower end of the limiting block (74) presses the bag to heat seal the bag opening. After heat sealing, the heat sealing plate (73) and the sealing block (75) are reset, the second cylinder (52) drives the mounting box (53) and the clamping block (56) to reset, and the sealed bag is conveyed to the unloading end by the second conveyor belt (4) to complete the vacuum packaging of the imitation silk cotton roll.
