Description

Technical Field

[0001] The utility model relates to the field of packaging machinery and equipment, in particular to a weighing and packaging device for fragile goods. Background Art

[0002] When general packaging machines are packaging materials, they do not consider whether the materials are fragile. Therefore, fragile materials such as frozen fresh food (such as crayfish quick-frozen in liquid nitrogen, which has a fragile ice coat on the outside, which will affect the shelf life and hygiene of the crayfish if damaged), biscuits, glassware, etc. will be damaged when they fall into the carton body due to the large drop when using ordinary packaging equipment, which will greatly affect the appearance or quality of the finished product.

[0003] The traditional packaging method for fragile items is as follows: 1. A fully automatic carton opener opens and folds the carton boards into a top-opening carton; 2. The top-opening carton passes through a conveyor path and enters a carton bagging machine, where a plastic bag is automatically placed inside the top-opening carton; 3. The plastic-bag-lined carton then passes through a conveyor belt with workers on both sides. Workers remove the plastic-bag-lined carton from the conveyor belt and manually place the fragile items into the carton, weighing it. The carton containing the fragile items is then placed back on the conveyor belt; 4. Finally, the carton enters an automatic carton sealer to seal the top opening of the carton, and the finished product is shipped. This operation requires a large number of workers to keep up with the production efficiency of the carton bagging machines. The labor is high and lasts for a long time, leading to unpredictable worker errors and a high rate of finished product scrap. Utility Model Content

The number of weighing platforms corresponds one to one to the number of sliding grooves, and inclined parallel wide conveyor belts and narrow conveyor belts are arranged in the sliding groove. The wide conveyor belt and the narrow conveyor belt are respectively controlled by independent first motors. A material control baffle is provided at the outlet position of the wide conveyor belt, and the material control baffle is driven by a material control cylinder to extend and retract up and down. When the height of the narrow conveyor belt is greater than that of the wide conveyor belt, the outlets of the wide conveyor belt and the narrow conveyor belt are connected with a downward inclined material guide trough plate, and the outlet position of the material guide trough plate is provided with a first material baffle. The gap between the first material baffle plate and the bottom of the trough of the material guide trough plate forms an output port, which is close to the upper opening of the carton.

[0007] The material input mechanism includes a second material baffle plate arranged in front and back, and a first conveyor belt and a second conveyor belt arranged in an upper and lower position are arranged between the two second material baffle plates.

[0017] The present invention is described in detail below through examples, which are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.

[0018] like Figure 1As shown, this embodiment discloses a fragile goods weighing and packaging equipment, which includes a fully automatic carton opener 1, a carton inner bagging machine 2, an automatic carton sealing machine 3 and a checkweigher 4 in sequence. The carton board is placed in the fully automatic carton opener 1 to be opened into a box body with an upper opening. An automatic carton entry weighing machine 5 for fragile goods is also provided between the carton inner bagging machine 2 and the automatic carton sealing machine 3. Roller conveyor lines 6 (part of the roller conveyor lines can also be replaced by conveyor belts) are respectively provided between the fully automatic carton opener 1, the carton inner bagging machine 2, the automatic carton entry weighing machine 5 for fragile goods, the automatic carton sealing machine 3 and the checkweigher 4 for conveying cartons (opened) After the carton), the material enters the conveying carton through the automatic box-entry weighing machine 5 for fragile items. The automatic box-entry weighing machine 5 for fragile items includes a frame 51. The frame 51 is provided with a material input mechanism 52, a lane material control and output mechanism 53 and a weighing platform 54 in an inclined direction from top to bottom. The material input mechanism 52, the lane material control and output mechanism 53 and the weighing platform 54 are electrically connected to a control host respectively. A weighing sensor is arranged at the bottom of the weighing platform 54. A carton positioning and pushing mechanism 55 is provided between the roller conveyor line 6 and the weighing platform 54, so that a carton with the opening facing upward is placed on the weighing platform 54.

[0019] Specific as Figure 2-Figure 4 The discharge channel of the material input mechanism 52 is connected to the entrance of the lane control and output mechanism 53, and the outlet of the lane control and output mechanism 53 is close to the opening of the carton 5 on the weighing platform. The lane control and output mechanism 53 includes four limit blocks 531 arranged in sequence on the frame 51 in a horizontal direction, and five sliding grooves 532 inclined up and down are formed between the limit blocks 531 and between the limit blocks 531 and the side plates of the frame 51. The number of weighing platforms 54 corresponds to the number of sliding grooves 532. An inclined parallel wide conveyor belt 533 and a narrow conveyor belt 534 are provided in the sliding groove 532. The width of the narrow conveyor belt 534 is equivalent to the width of a material. The function of the narrow conveyor belt 534 is to feed the material. The wide conveyor belt 533 and the narrow conveyor belt 534 are respectively controlled by an independent first motor. A material control baffle 535 is provided at the outlet position of the wide conveyor belt 533. The material control baffle 535 is driven by a material control cylinder 536 to extend and retract up and down. The material control cylinder 536 is installed on a straight rod and is connected to the air pump through a solenoid valve. The height of the narrow conveyor belt 534 is greater than the height of the wide conveyor belt 533. The outlets of the wide conveyor belt 533 and the narrow conveyor belt 534 are connected with a downward inclined material guide trough plate 537. The outlet position of the material guide trough plate 537 is provided with a first material baffle plate 538. The gap between the first material baffle plate 538 and the bottom of the trough of the material guide trough plate 537 forms an output port, which is close to the upper opening of the carton 5 on the weighing platform. When the material passes through the output port, it can be blocked by the first material baffle plate 538, avoiding stacked output, so that the material can slide out into the carton smoothly and reliably.

[0020] The material input mechanism 52 includes a second baffle plate 521 set up at the front and rear, and a first conveyor belt 522 and a second conveyor belt 523 set up above and below are provided between the two second baffle plates 521. The first conveyor belt 522 and the second conveyor belt 523 are arranged in an inclined and flat manner and are respectively controlled by an independent second motor 20. The conveying directions of the first conveyor belt 522 and the second conveyor belt 523 are arranged in opposite directions. The front and rear ends of the first conveyor belt 522 and the second conveyor belt 523 are respectively provided with a partition plate 524, which is plug-matched and connected with the card slots on the two second baffle plates. The gap between the second baffle plate 521 and the second conveyor belt 523 forms a discharge channel 525. After the material is poured onto the first conveyor belt 522 and the second conveyor belt 523, since the conveying directions of the first and second conveyor belts are opposite, the material can be laid more evenly on the first and second conveyor belts, and slide out from the discharge channel from the second conveyor belt 523 located at the bottom and enter the various sliding grooves 532 in the channel control output mechanism 53 in a balanced and orderly manner.

[0021] The cross section of the stop block 531 is in the shape of an isosceles triangle, which allows the sliding trough 532 to have a wider edge protection, making it easier for materials (frozen fresh food) to pass through.

[0022] The first conveyor belt 522, the second conveyor belt 523, the wide conveyor belt 533, the narrow conveyor belt 534 and the material guide trough plate 537 form a channel for inclined conveying of materials, so that the height difference from the carton 5 is gradually reduced to avoid damage to the materials due to excessive height difference when falling into the carton 5.

[0023] In this way, after the material is poured into the material input mechanism 52, it is sorted and output to the channel material control and output mechanism 53, and is output to the weighing platform 54 for timely weighing through the wide conveyor belt 533 in the channel material control and output mechanism 53. When the weight in the carton 5 is close to the weight set by the control host for the weighing platform 54, the material control baffle 535 moves down to block the material on the wide conveyor belt 533. At this time, the material is output through the narrow conveyor belt 534 to replenish the material, so that the material in the carton 5 accurately reaches the weighing weight set by the control host. Since the material input mechanism 52, the channel material control and output mechanism 53 and the weighing platform 54 are inclined from top to bottom, the material can be gradually lowered in the transportation process. When entering the carton 5, the height difference is very small, thus achieving the technical effect of placing fragile items in the carton 5 with a small height difference and accurately weighing, thereby avoiding material breakage. When the material is frozen fresh food, its ice coating is also avoided from being damaged.

[0024] Specific as Figure 5 、 Figure 6As shown, the carton positioning and pushing mechanism 55 includes a position sensor, a pushing plate 551 and a positioning plate 552 installed on the frame 51. The positioning plate 552 is located in the gap between the rollers in the roller conveyor line 6 and can be extended and retracted up and down. The positioning plate 552 is installed on a cross bar 553 in turn, and the cross bar 553 is installed on the output shaft of a first cylinder 554. The pushing plate 551 is located on the side of the upper interval position of the positioning plate 552. A second cylinder 555 is provided corresponding to the pushing plate 551. The piston rod of the second cylinder 555 is connected to the third cylinder 556. The piston rod of the third cylinder 556 is connected to the pushing plate 551. The position sensor is electrically connected to the control host. When the position sensor detects that the carton on the roller conveyor line 6 is moving, the signal is transmitted to the control host for processing. The control host controls the first cylinder 554 to lift the positioning plate 552. The positioning plate 552 positions the carton and aligns it with the weighing platform 54. Then the second cylinder 555 outputs and acts on the pushing plate 551 to push the carton to the weighing platform 54 to add materials and weigh it. After the weighing is completed, the third cylinder 556 acts on the pushing plate 551 to push the carton to the roller conveyor line 6 on the other side after the material is added to continue the next process.

[0025] Among them, the fully automatic carton opener 1, the carton inner bagging machine 2, the automatic carton sealing machine 3 and the weight checker 4 are all purchased machines, which require manual participation during operation and are also existing technologies. The specific structure will not be repeated here.

[0026] By adopting the above technical solution, the carton board is opened into a carton with an opening at the top by the fully automatic carton opener 1 and output to the carton inner bagging machine 2 through the roller conveyor line 6 to put a plastic bag in the carton, and then enters the automatic box entering and weighing machine 5 for fragile goods to put the fragile materials into the carton, and then the plastic bag can be manually sealed, and then enters the automatic box sealing machine 3 to seal the carton, and finally the weight is manually checked again by the weighing machine 4 to complete the packaging. In the automatic box entering and weighing machine 5 for fragile goods, since the material input mechanism 52, the channel material control and output mechanism 53 and the weighing platform 54 are inclined from top to bottom, the material can be gradually lowered in the transportation process. When entering the carton, the drop is very small, so that the material is not easily broken when falling into the carton, thereby achieving the technical effect of automatically packing and packaging fragile goods, thereby improving production efficiency.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
