Description

Technical Field

[0001] This utility model relates to the technical field of prefabricated food tray packaging equipment, specifically a prefabricated food tray packaging sealing device. Background Technology

[0002] With the rapid development of the pre-prepared food industry, consumers' requirements for packaging sealing, hygiene and production efficiency continue to increase. As the mainstream packaging carrier, pre-prepared food trays need to be sealed by sealing devices to ensure quality during storage and transportation and to avoid leakage and deterioration. Therefore, tray sealing has become a key process in the production of pre-prepared food. Currently, the sealing devices for pre-prepared food trays on the market still rely heavily on manual operation. The typical process is as follows: the operator manually places the trays containing the pre-prepared food to be sealed one by one into the mold station of the device and ensures accurate positioning. Then the sealing equipment starts to complete the sealing. Finally, the sealed trays need to be manually removed from the mold before the next batch of processing can begin. This solution has significant flaws, the core problem being low production efficiency: both loading and unloading rely on manual operation, resulting in an intermittent sealing process that cannot form a continuous production flow. The speed of manual operation is limited by skill level and physical strength, making it difficult to match the high efficiency of machine-controlled hot-press sealing. Loading and unloading stages easily become production bottlenecks, severely restricting the overall production line efficiency and failing to meet the needs of large-scale, mass production in the pre-prepared food industry.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figures 1-5 This utility model provides a prefabricated food tray packaging sealing device, including a processing table 1 and a sealing device 19. A limiting plate 2 is fixedly installed at the upper end of the processing table 1. A bearing seat 4 is provided on the front side of the limiting plate 2. The bearing seat 4 is slidably connected to the processing table 1. A plurality of placement slots 5 are provided on the bearing seat 4. A partition is provided between the plurality of placement slots 5. An opening 6 is provided on the rear side of the placement slot 5. A slide 3 is provided in the middle part of the limiting plate 2. A plurality of second pushing components 20 are fixedly installed at the front end of the bearing seat 4. A push plate 21 is provided at the front end of the placement slot 5. A third drive rod that penetrates the bearing seat 4 and connects to the push plate 21 is provided at the output end of the second pushing components 20. Two limiting frames 12 are symmetrically arranged on the left and right sides of the rear side of the slide 3. The limiting frames 12 are equipped with limiting components. The rear end of the limiting frame 12 is equipped with a baffle 15. The processing table 1 is equipped with a slot 17 located below the baffle 15. The baffle 15 vertically penetrates the slot 17 and is slidably connected to the slot 17. A lifting component 16 is fixedly arranged below the processing table 1. The output end of the lifting component 16 is equipped with a second drive rod connected to the baffle 15. The sealing device 19 is fixed above the limiting frame 12. The processing table 1 has a second conveyor table 18 located behind the limit frame 12 at its rear end, and a first conveyor table 11 located in front of the bearing seat 4 at its front end.

[0014] The specific working process of this prefabricated food tray packaging sealing device is as follows: The pre-made food trays to be sealed are intermittently conveyed by the first conveyor 11. The operator takes the trays to be sealed from the first conveyor 11 and places them into the designated placement slots 5 on the support seat 4 (the placement slots 5 are separated by partitions to avoid interference between the trays).

[0015] The support seat 4 is located on the upper end of the processing table 1. The processing table 1 is provided with a sliding groove 7. The lower end of the support seat 4 is provided with a bottom block 8 that passes through the sliding groove 7 and is slidably connected to the processing table 1. A motor 9 is fixedly installed on one side of the processing table 1. The output end of the motor 9 is provided with a threaded rod 10 that passes through the bottom block 8 and is threadedly connected to the bottom block 8. The upper end of the processing table 1 is provided with two guide grooves symmetrically arranged in the sliding groove 7. The lower end of the support seat 4 is provided with two guide blocks symmetrically arranged in the bottom block 8 that are inserted into the guide grooves. The cross-section of the guide groove is T-shaped, and the cross-section of the sliding groove 7 is rectangular.

[0016] After the motor 9 is started, the threaded rod 10 at the output end of the motor 9 drives the bottom block 8 through the slide groove 7 to slide, thereby causing the bearing seat 4 to move along the processing table 1; At this time, the guide block at the lower end of the bearing seat 4 slides synchronously along the T-shaped guide groove at the upper end of the processing table 1 (the cross section of the slide groove 7 is rectangular), ensuring that the bearing seat 4 moves stably until the opening 6 on the rear side of the placement groove 5 is aligned with the slide 3 in the middle of the limiting plate 2.

[0017] Subsequently, the second propulsion component 20 corresponding to the placement slot 5 is activated, and the third drive rod at its output end pushes the push plate 21 at the front end of the placement slot 5, pushing the pre-made food tray box in the placement slot 5 through the opening 6 and the slide 3 to the space between the two limit frames 12.

[0018] The limiting component includes a positioning plate 13 and a first propulsion component 14. The first propulsion component 14 is fixed on the outside of the limiting frame 12, the positioning plate 13 is located on the inside of the limiting frame 12, the positioning plate 13 has a positioning groove on its inside, and the output end of the first propulsion component 14 has a first drive rod that passes through the limiting frame 12 and is connected to the positioning plate 13.

[0019] At this time, the first push component 14 on the outer side of the limit frame 12 is activated, and the first drive rod at its output end drives the positioning plate 13 on the inner side of the limit frame 12 to move. The positioning plate 13 clamps and positions the tray through the positioning groove on the inner side of the positioning plate 13 to ensure the accurate position of the tray.

[0020] The inner wall of the rear end of the limiting frame 12 is provided with a limiting groove, and the two sides of the baffle 15 are inserted into the limiting groove and slidably connected with the limiting frame 12.

[0021] After positioning is completed, the sealing device 19, fixed above the limiting frame 12, is started to seal the tray. After sealing is completed, the lifting assembly 16 below the processing table 1 is started, and the second drive rod at its output end drives the baffle 15 to descend vertically along the empty groove 17 (the baffle 15 vertically penetrates the empty groove 17) and the limiting groove on the inner wall of the rear end of the limiting frame 12 (the limiting groove ensures that the baffle 15 rises and falls stably), thus removing the obstruction to the tray.

[0022] Next, the second propulsion component 20 continues to drive the push plate 21 to push the sealed tray from between the limit frames 12 to the second conveyor 18 at the rear of the processing table 1, completing the automatic material discharge.

[0023] Afterwards, the push plate 21 is reset under the drive of the second propulsion component 20, and the motor 9 drives the carrier 4 to move again, so that the opening 6 of the next placement slot 5 is aligned with the slide 3 again, ready for the next loading; at this time, the operator can put the new sealing tray into the empty placement slot 5 to realize the cycle operation.

[0024] The partition between the slots 5 prevents the trays from interfering with each other, and the cooperation between the opening 6 and the slide 3 ensures a smooth pushing path. Each drive component (motor 9, first propulsion component 14, second propulsion component 20, lifting component 16) transmits power precisely through the drive rod. The overall structure is compact and highly interconnected, and can operate stably for a long time, adapting to industrial production environments.

[0025] Motor 9: Functional requirements: The bearing seat 4 should be able to slide smoothly along the processing table 1 to achieve precise alignment between the placement slot 5 and the slide rail 3. Position control capability is required.

[0026] Model selection: 42 series stepper motor (e.g., 42BYGH34), matching driver (e.g., TB6600).

[0027] Reason: The stepper motor can precisely control the rotation angle through pulse signals, and the threaded rod 10 is matched with the transmission to achieve precise positioning of the bearing seat 4; the torque of the 42 series (0.5-0.8N・m) is sufficient to drive light-load sliding, and it is small in size and moderate in cost, making it suitable for small equipment.

[0028] First propulsion component 14: Functional requirements: Push the positioning plate 13 to move laterally to clamp / release the tray. The load is the weight of the positioning plate 13. The action must be fast and smooth (response time < 0.5s).

[0029] Model selection: small pneumatic cylinder (such as SC16×20), with matching solenoid valve (such as 4V210-08).

[0030] Reasons: The cylinder has a simple structure and fast response, making it suitable for short-stroke, high-frequency actions; the SC16 cylinder diameter (16mm) and 20mm stroke can meet the clamping force (approximately 50-100N) requirement of the positioning plate, and the pneumatic drive has high cleanliness, making it suitable for food production environments.

[0031] Second propulsion component 20: Functional requirements: Push the push plate 21 to move longitudinally along the placement groove 5, and push the tray from the placement groove 5 to the limit frame 12 or the second conveyor table 18 via the slide 3. The load is the weight of the tray (about 0.5-1kg), and the pushing speed must be stable (to avoid tilting the tray).

[0032] Model selection: Electric linear actuator (e.g., DT16-100).

[0033] Reason: The electric push rod can control the pushing distance and speed through a voltage signal (DC24V), which makes it easier to achieve precise speed adjustment compared to a cylinder, and avoids the tray from shifting due to excessive impact during pushing; the 16mm push rod diameter and 100mm stroke can cover most tray pushing needs.

[0034] Lifting assembly 16 (drive baffle 15 to lift): Functional requirements: Drive the baffle 15 to move vertically up and down along the empty slot 17 / limiting slot to block / release the tray. The load is the weight of the baffle 15 (about 1-2kg). The action must be fast and reliable (lifting time < 0.3s).

[0035] Model selection: small pneumatic cylinder (such as SC12×30), with matching solenoid valve (same as the first propulsion assembly 14, 4V210-08).
