Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing equipment, specifically to a food packaging device for food processing. Background Technology
[0002] Food processing refers to the process of transforming agricultural, forestry, animal husbandry, and fishery products into finished or semi-finished products suitable for human consumption through a series of physical, chemical, or biological methods. After processing, food needs to be packaged for easy storage and transportation.
[0003] To further understand existing food packaging equipment, a search revealed Chinese Patent No. CN220905517U, which discloses a food packaging device, including an operating table with packaging bags; a base fixedly installed at the bottom of the operating table; a mounting plate fixedly installed on the base, corresponding to the operating table; a movable slot formed on the mounting plate, corresponding to the operating table; a heating strip fixedly installed on the operating table; two transmission mechanisms, both disposed on the movable slot for transmitting packaging bags, corresponding to the operating table; and a sealing mechanism disposed on the mounting plate for sealing the packaging bags, corresponding to the heating strip. Although the patent improves food packaging efficiency by using two transmission mechanisms in conjunction with the heating strip, during the process of using the heating strip to seal plastic bags, the molten part of the plastic bag will stick to the heating strip. When the heating strip is lifted after sealing, the molten plastic bag will move with it, which can easily cause damage to the sealing position and reduce the quality of food packaging. Utility Model Content
[0004] In the existing process of sealing plastic packaging bags with electric heating strips, the molten part of the plastic packaging bag will stick to the electric heating strip. When the electric heating strip is lifted after sealing, the molten plastic packaging bag will move with it, which can easily cause damage to the sealing position and reduce the quality of food packaging. This utility model provides a food packaging equipment for food processing.
[0005] The technical solution adopted by this utility model is as follows: It includes a processing table, a fixed base fixedly connected to the processing table, a lower heat sealer fixedly installed on the fixed base, an mounting base fixedly connected to the processing table, a cylinder fixedly installed on the mounting base, a pressure plate fixedly connected to the bottom of the piston rod of the cylinder, an upper heat sealer fixedly installed at the bottom of the pressure plate, the upper heat sealer being compatible with the lower heat sealer, four sets of through holes opened on the pressure plate, slide rods slidably installed in each of the four sets of through holes, pressure rollers provided at the bottom of two sets of slide rods, springs sleeved on the outside of the slide rods, and baffles fixedly connected to the top of the slide rods, a pressure bearing seat fixedly installed on the processing table, the pressure bearing seat being compatible with the pressure rollers, and a conveying mechanism provided on the processing table.
[0006] Furthermore, mounting brackets are fixedly installed at the bottom of the two sets of slide bars, and the pressure rollers are rotatably installed in the mounting brackets.
[0007] By adopting the above technical solution, the pressing effect of the pressure roller on the sealing part of the food packaging bag is improved.
[0008] Furthermore, the pressure plate is provided with two sets of limiting holes, and limiting posts are slidably installed in the two sets of limiting holes. The limiting posts are fixedly installed between the fixed seat and the mounting seat.
[0009] By adopting the above technical solution, the stability of the upper heat sealer during movement is improved.
[0010] Furthermore, the conveying mechanism includes a stepper motor installed outside the processing table, two sets of rotating shafts rotatably installed in the processing table, and a conveyor belt set in the processing table. Each of the two sets of rotating shafts is fixedly mounted with a transmission roller. The conveyor belt is sleeved outside the two sets of transmission rollers. One set of rotating shafts is coaxially and fixedly connected to the drive shaft of the stepper motor.
[0011] By adopting the above technical solution, the food packaging bags to be packaged and after packaging are transported, thereby improving processing efficiency.
[0012] Furthermore, several sets of limiting blocks are fixedly installed on the conveyor belt, and food packaging bags are placed on the conveyor belt.
[0013] By adopting the above technical solutions, the stability of food packaging bags after placement can be improved.
[0014] Furthermore, a lower guide plate is fixedly installed on the processing table, and an upper guide plate is also fixedly connected to the processing table. Both the upper guide plate and the lower guide plate have arc-shaped surfaces on their opposite sides.
[0015] By adopting the above technical solution, the openings of the food packaging bags to be sealed are made to fit together, which facilitates the sealing operation.
[0016] The beneficial effects of this utility model are as follows: the upper heat sealer moves downward by means of the mounting base, cylinder and pressure plate. The upper heat sealer works with the lower heat sealer to heat seal the opening of the food packaging bag. The pressure plate works with the slide bar, mounting frame, spring and pressure roller to make the pressure roller contact the opening of the food packaging bag with the upper heat sealer and press it down, so as to avoid the food packaging bag from shifting during sealing. After sealing, the pressure roller moves upward only after the upper heat sealer leaves the food packaging bag, so as to avoid the molten part of the food packaging bag moving with it when the upper heat sealer is lifted after heat sealing, which would cause the sealing to break. This improves the food packaging quality.
[0017] The food packaging bags are transported by a stepper motor in conjunction with a rotating shaft, drive rollers, and a conveyor belt, which improves the convenience of transporting and the efficiency of sealing. The conveyor belt, together with limit blocks, restricts the food packaging bags and reduces deviation during transport and sealing. The conveyor belt, together with upper and lower guide plates, ensures that the upper and lower ends of the opening of the food packaging bag are fitted together before sealing, reducing wrinkles at the opening of the food packaging bag during sealing. This helps to improve the sealing quality of the food packaging bags and enhances the practicality of the equipment. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0026] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.
[0027] To address the problems existing in the background art, this application proposes the following technical solution: A processing table 1 is included, a fixed base 2 is fixedly connected to the processing table 1, a lower heat sealer 3 is fixedly installed on the fixed base 2, an mounting base 4 is fixedly connected to the processing table 1, a cylinder 5 is fixedly installed on the mounting base 4, a pressure plate 6 is fixedly connected to the bottom of the piston rod of the cylinder 5, an upper heat sealer 7 is fixedly installed at the bottom of the pressure plate 6, the upper heat sealer 7 is compatible with the lower heat sealer 3, four sets of through holes 8 are provided on the pressure plate 6, slide rods 9 are slidably installed in each of the four sets of through holes 8, pressure rollers 11 are provided at the bottom of two sets of slide rods 9, springs 12 are sleeved on the outside of the slide rods 9, a baffle 13 is fixedly connected to the top of the slide rods 9, a pressure bearing seat 14 is fixedly installed on the processing table 1, the pressure bearing seat 14 is compatible with the pressure rollers 11, and a conveying mechanism is provided on the processing table 1.
[0028] The food packaging bag 22 (made of plastic) is moved between the lower heat sealer 3 and the upper heat sealer 7 by a conveying mechanism. The piston rod of the cylinder 5 drives the pressure plate 6 to move downward, and the pressure plate 6 drives the upper heat sealer 7 to move downward. The upper heat sealer 7, together with the lower heat sealer 3, heat seals the opening of the food packaging bag 22 placed between them, completing the sealing operation of the food packaging bag 22. During the sealing operation, the pressure plate 6 drives the pressure roller 11 to move downward with the upper heat sealer 7 through the slide rod 9 and the spring 12. Before the upper heat sealer 7 and the lower heat sealer 3 cooperate to heat seal, the pressure roller 11 first contacts the pressure seat 14 to press the opening of the food packaging bag 22, effectively preventing the opening of the food packaging bag 22 from shifting on the lower heat sealer 3 during the heat sealing process, thus improving the heat sealing effect. As the pressure seat 14 moves downward, it applies pressure to the pressure roller 11, causing the slide bar 9 to move upward in the through hole 8. The spring 12 is compressed and deformed. After heat sealing, the cylinder 5 drives the pressure plate 6 and the upper heat sealer 7 to move upward. During this process, the compressed spring 12 pushes the pressure roller 11 downward to press the food packaging bag 22 before returning to its initial state. This prevents the molten part of the food packaging bag 22 from moving with the upper heat sealer 7 when it is lifted after heat sealing, thus avoiding damage to the sealing area and improving the food packaging quality. After the upper heat sealer 7 moves away from the heat-sealed food packaging bag 22 by a certain distance, the pressure plate 6 drives the slide bar 9 to move upward through the baffle 13. The slide bar 9 drives the pressure plate 6 to move upward, causing the pressure roller 11 to leave the pressure seat 14, which facilitates the subsequent sealing operation of the food packaging bag 22.
[0029] Furthermore, the bottom of the two sets of slide bars 9 are fixedly mounted with mounting brackets 10, and the pressure rollers 11 are rotatably mounted in the mounting brackets 10.
[0030] The pressure roller 11 is connected to the bottom of the slide bar 9 via the mounting bracket 10. When the pressure roller 11 presses the opening of the food packaging bag 22, it can rotate in the mounting bracket 10 to avoid the pressure roller 11 directly pressing the food packaging bag 22 and causing it to wrinkle, thereby improving the sealing quality.
[0031] Furthermore, the pressure plate 6 has two sets of limiting holes 15, and limiting posts 16 are slidably installed in the two sets of limiting holes 15. The limiting posts 16 are fixedly installed between the fixed seat 2 and the mounting seat 4.
[0032] The limiting hole 15, together with the limiting post 16, guides and limits the movement of the pressure plate 6, so that the pressure plate 6 can only move in the vertical direction, improving the stability of the upper heat sealer 7 and the lower heat sealer 3 during heat sealing, and ensuring the sealing quality of the food packaging bag 22.
[0033] To further explain, the conveying mechanism includes a stepper motor 17 installed outside the processing table 1, two sets of rotating shafts 18 rotatably installed in the processing table 1, and a conveyor belt 20 set in the processing table 1. Each set of rotating shafts 18 is fixedly mounted with a transmission roller 19, and the conveyor belt 20 is sleeved outside the two sets of transmission rollers 19. One set of rotating shafts 18 is coaxially and fixedly connected to the drive shaft of the stepper motor 17.
[0034] Stepper motor 17 drives a set of rotating shafts 18 and transmission rollers 19 to rotate. One set of transmission rollers 19 drives another set of transmission rollers 19 to rotate via conveyor belt 20. The rotating conveyor belt 20 facilitates the transport of the food packaging bag 22 to be packaged to the packaging operation position, and also facilitates the transport of the packaged food packaging bag 22 to the subsequent work station, thereby improving the convenience of transporting the food packaging bag 22 and the packaging efficiency.
[0035] Furthermore, several sets of limit blocks 21 are fixedly installed on the conveyor belt 20, and food packaging bags 22 are placed on the conveyor belt 20.
[0036] The food packaging bag 22 is placed between two sets of adjacent limiting blocks 21. The two sets of limiting blocks 21 play a certain limiting role on the food packaging bag 22, reducing the deviation of the food packaging bag 22 during the conveying and sealing process, and improving the practicality of the equipment.
[0037] Furthermore, a lower guide plate 23 is fixedly installed on the processing table 1, and an upper guide plate 24 is also fixedly connected to the processing table 1. Both the upper guide plate 24 and the lower guide plate 23 have arc-shaped surfaces on their opposite sides.
[0038] The arc-shaped surfaces on the opposite side of the upper guide plate 24 and the lower guide plate 23 are located on the side away from the mounting base 4. The food packaging bag 22 to be packaged moves to the lower guide plate 23 and the upper guide plate 24 via the conveyor belt 20. The arc-shaped surfaces of the upper guide plate 24 and the lower guide plate 23, together with the conveyor belt 20, make the upper and lower sides of the opening of the food packaging bag 22 fit together, reducing wrinkles at the opening of the food packaging bag 22 during packaging, which helps to improve the packaging quality of the food packaging bag 22 and improve the practicality of the equipment.
[0039] The specific operation is as follows: Place the food packaging bag 22 between two sets of adjacent limiting blocks 21 on the conveyor belt 20. The conveyor belt 20 moves the food packaging bag 22. The arc-shaped surfaces of the upper guide plate 24 and the lower guide plate 23 fit together to make the upper and lower sides of the opening of the food packaging bag 22 stick together. Then, the food packaging bag 22 moves between the lower heat sealer 3 and the upper heat sealer 7. Then, the piston rod of the cylinder 5 drives the pressure plate 6 to move downward. The pressure plate 6 drives the upper heat sealer 7 to move downward. At the same time, the pressure plate 6 drives the pressure roller 11 to move downward. Before the upper heat sealer 7 and the lower heat sealer 3 cooperate to heat seal, the pressure roller 11 first contacts the pressure seat 14 to press the opening of the food packaging bag 22. The spring 12 releases... As the pressure plate 6 moves downward, the upper heat sealer 7, in conjunction with the lower heat sealer 3, heat seals the opening of the food packaging bag 22 placed between them, completing the sealing operation of the food packaging bag 22. After sealing, the cylinder 5 drives the pressure plate 6 and the upper heat sealer 7 to move upward. The compressed spring 12 keeps the pressure roller 11 on the pressure seat 14 to press the food packaging bag 22. After the upper heat sealer 7 moves away from the heat-sealed food packaging bag 22 by a certain distance, the pressure plate 6 drives the slide bar 9 to move upward through the baffle 13. The slide bar 9 drives the pressure plate 6 to move upward, causing the pressure roller 11 to leave the pressure seat 14. The conveyor belt 20 transports the sealed food packaging bag 22 to the subsequent work station.
