Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a food processing sealing device. Background Technology

[0002] Food processing refers to the processing of grains, feed, vegetable oils and sugars, slaughtering and meat processing, aquatic products, and other foods such as vegetables, fruits, and nuts, using agricultural, forestry, animal husbandry, and fishery products as raw materials. It also includes the processing of potatoes, dehydrated vegetables, and canned vegetables. It is a type of agricultural product processing industry in a broad sense. Sealing devices are required to seal packaging bags during food processing.

[0003] The existing Chinese patent with publication number CN216806077U discloses a sealing mechanism for packaging bags used in food processing. However, the existing technical solution has the following drawbacks: Although the servo motor drives the rotating rod and the active conical wheel to rotate counterclockwise, and the active conical wheel meshes with the driven conical wheel, causing the driven conical wheel and the threaded rod to rotate clockwise, the left driven conical wheel and the right conical wheel rotate relative to each other after being meshed with the active conical wheel. This causes the left and right threaded rods to rotate in opposite directions. At this time, the threaded strip on the outer side of the threaded rod and the threaded block inside... The threaded grooves on the sidewalls engage with the threads, and a limiting component restricts the position of the threaded block. Because the left and right threaded rods rotate in opposite directions, the threaded block shifts to the opposite side, thus moving the heat-sealing component to the opposite side until it presses against the bag opening and heat-seals it, achieving efficient sealing. However, this technical solution relies on manual, continuous hand-holding of the bag to maintain its position, lacking an automated bag opening support mechanism. This not only reduces sealing efficiency but also increases the workload of operators. More specifically, due to the lack of bag positioning and fixing functions, the bag opening may shift due to unstable manual holding during heat sealing, potentially affecting sealing quality.

[0005] To address the shortcomings of existing technologies, this utility model provides a food processing sealing device that can automatically support the packaging bag, prevent the packaging bag from shifting during sealing, and achieve high sealing quality, thereby solving the problems mentioned in the background technology.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a food processing sealing device, comprising a box body, support plates fixedly connected to both sides of the top surface of the box body, and a horizontal plate fixedly installed between the support plates, a dual-axis motor fixedly installed at the middle position of the top surface of the horizontal plate, and a lead screw fixedly connected to the output end of the dual-axis motor, a moving block threadedly connected to the lead screw, and a connecting block fixedly connected to the bottom surface of the moving block through the connecting grooves opened on both sides of the top surface of the horizontal plate, one side surface of the connecting block fixedly connected to a connecting rod below the horizontal plate, and an electric heating sealing plate fixedly installed at one end of the connecting rod, a servo motor fixedly installed at the middle position of the upper surface of the bottom end of the box body, and a screw fixedly connected to the output end of the servo motor, a threaded cylinder threadedly connected to the screw, and a support base fixedly connected to the top end of the threaded cylinder through the top surface of the box body, a connecting frame inclinedly provided on both sides of the top surface of the support base, and a compression cylinder installed at the end of the connecting frame, a limiting block provided on both sides of the threaded cylinder, and one end of the limiting block extending into the interior of the limiting grooves opened on both sides of the inner wall of the box body.

[0008] Preferably, side plates are fixedly connected to both sides of the support base, and springs are fixedly installed between the side plates and the connecting frame.

[0009] Preferably, there are two support plates, and a limiting rod is provided through the moving block between the two support plates, and the moving block is slidably connected to the limiting rod.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a food processing sealing device, which has the following beneficial effects:

[0017] (1) In this utility model, after the packaging bag to be sealed is placed on the support base, the servo motor is started to drive the screw to rotate. Under the constraint of the limiting block and the limiting groove, the threaded cylinder moves along the screw axis and drives the support base to rise and fall synchronously, thereby accurately adjusting the vertical position of the packaging bag. When the opening of the packaging bag reaches the preset work position (between the electric heating sealing plates), the dual-axis motor drives the lead screw to rotate. Through the guide constraint of the limiting rod on the moving block, the moving block drives the connecting block and the connecting rod to make linear movements, and finally drives the electric heating sealing plates on both sides to complete the opposite closing action, realizing automated sealing. This device replaces manual intervention with mechanical support to ensure the consistency of the sealing position, thereby improving its processing quality.

[0018] (2) In this utility model, by pulling the connecting frame outward to drive the extrusion cylinder to move, the packaging bag is placed on the support seat and the connecting frame is released. Under the reset action of the spring between the side plate and the connecting frame, the extrusion cylinder automatically presses against the lower part of the sealing part of the packaging bag. The clamping mechanism realizes the automatic centering and fixing of the packaging bag through elastic pressure, effectively preventing the sealing misalignment problem caused by the bag body offset during the sealing process. The pre-tightening force of the spring can ensure that the extrusion cylinder can form a stable constraint on packaging bags of different thicknesses, which not only avoids the deformation of the bag body that may be caused by rigid clamping, but also improves the consistency of the sealing position, providing a reliable positioning guarantee for the subsequent sealing process, thereby ensuring the stability and accuracy of the sealing process.

[0028] Please refer to Figure 1-4A food processing sealing device includes a housing 1. Support plates 2 are fixedly connected to both sides of the top surface of the housing 1, and a horizontal plate 11 is fixedly installed between the support plates 2. A dual-axis motor 10 is fixedly installed at the middle position of the top surface of the horizontal plate 11, and a lead screw 9 is fixedly connected to the output end of the dual-axis motor 10. A moving block 8 is threaded onto the lead screw 9, and a connecting block 4 is fixedly connected to the bottom surface of the moving block 8 through connecting grooves 12 opened on both sides of the top surface of the horizontal plate 11. A connecting rod 5 is fixedly connected to one side surface of the connecting block 4 below the horizontal plate 11, and an electric heating sealing plate 6 is fixedly installed at one end of the connecting rod 5. A servo motor 7 is fixedly installed at the middle position of the upper surface of the bottom end of the housing 1, and a screw 15 is fixedly connected to the output end of the servo motor 7. A threaded cylinder 14 is threaded onto the screw 15, and a support base 13 is fixedly connected to the top end of the threaded cylinder 14 through the top surface of the housing 1. The top surface of the support base 13 is inclined with connecting frames 19 on both sides, and the ends of the connecting frames 19 are equipped with extrusion cylinders 18. The two sides of the threaded cylinder 14 are provided with limiting blocks 17, and one end of the limiting block 17 extends into the interior of the limiting grooves 16 opened on both sides of the inner wall of the box 1. After the packaging bag to be sealed is placed on the support base 13, the servo motor 7 is started to drive the screw 15 to rotate. Under the constraint of the limiting blocks 17 and the limiting grooves 16, the threaded cylinder 14 moves axially along the screw 15 and drives the support base 13 to rise and fall synchronously, thereby accurately adjusting the vertical position of the packaging bag. When the opening of the packaging bag reaches the preset work position (between the electric heating sealing plates 6), the dual-axis motor 10 drives the lead screw 9 to rotate. Through the guiding constraint of the limiting rod 3 on the moving block 8, the moving block 8 drives the connecting block 4 and the connecting rod 5 to make linear movements, and finally drives the two electric heating sealing plates 6 to complete the opposite closing action, realizing automated sealing.

[0029] In one embodiment, side plates 20 are fixedly connected to both sides of the support base 13, and a spring 21 is fixedly installed between the side plates 20 and the connecting frame 19. By pulling the connecting frame 19 outward, the extrusion cylinder 18 is moved. After the packaging bag is placed on the support base 13, the connecting frame 19 is released. Under the reset action of the spring 21 between the side plates 20 and the connecting frame 19, the extrusion cylinder 18 automatically presses against the lower part of the sealing part of the packaging bag. This clamping mechanism realizes the automatic centering and fixing of the packaging bag through elastic pressure, effectively preventing the sealing misalignment problem caused by the bag body displacement during the sealing process.

[0030] In one embodiment, there are two support plates 2, and a limiting rod 3 is provided through the moving block 8 between the two support plates 2. The moving block 8 is slidably connected to the limiting rod 3. By using the limiting rod 3, the moving block 8 on the lead screw 9 can be limited, thereby maintaining the normal movement of the moving block 8 on the lead screw 9.

[0031] In one embodiment, the connecting block 4 and the connecting groove 12 are rectangular structures. The connecting block 4 and the connecting groove 12 are slidably connected, allowing the connecting block 4 to move within the connecting groove 12, thereby adjusting the positional distance between the two electric heating sealing plates 6.

[0032] In one embodiment, the threaded cylinder 14 is movably connected to the housing 1, which enables the threaded cylinder 14 to move normally on the screw 15 and allows for adjustment of the height of the support 13, facilitating the sealing of packaging bags of different heights.

[0033] In one embodiment, a movable plate 22 is installed on the front surface of the housing 1, and the movable plate 22 is fixedly connected to the housing 1 by screws. By loosening the screws and removing the movable plate 22, the components in the housing 1 can be maintained and repaired.

[0034] In one embodiment, the limiting block 17 and the limiting groove 16 are rectangular structures. One end of the limiting block 17 extends into the interior of the limiting groove 16 and is slidably connected to the limiting groove 16. The use of the limiting block 17 and the limiting groove 16 can limit the threaded cylinder 14 on the screw 15, thereby maintaining the normal movement of the threaded cylinder 14 on the screw 15.

[0035] In one embodiment, one end of the connecting frame 19 is rotatably connected to the support base 13 via a pin, which allows adjustment of the position of the extrusion cylinder 18 at one end of the connecting frame 19.

[0036] In one embodiment, the control switch control circuit can be implemented by simple programming by those skilled in the art, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0037] Working principle:

[0038] In use, after placing the packaging bag to be sealed on the support base 13, the servo motor 7 is started to drive the screw 15 to rotate. Under the constraint of the limit block 17 and the limit groove 16, the threaded cylinder 14 moves axially along the screw 15 and drives the support base 13 to rise and fall synchronously, thereby accurately adjusting the vertical position of the packaging bag. When the opening of the packaging bag reaches the preset working position (between the electric heating sealing plates 6), the dual-axis motor 10 drives the lead screw 9 to rotate. Through the guide constraint of the limit rod 3 on the moving block 8, the moving block 8 drives the connecting block 4 and the connecting rod 5 to make linear movements, and finally drives the electric heating sealing plates 6 on both sides to complete the opposite closing action, realizing automated sealing. The connecting frame 19 is pulled outward to drive the... As the extrusion cylinder 18 moves, the packaging bag is placed on the support base 13, and the connecting frame 19 is released. Under the reset action of the spring 21 between the side plate 20 and the connecting frame 19, the extrusion cylinder 18 automatically presses against the lower part of the sealing section of the packaging bag. This clamping mechanism achieves automatic centering and fixing of the packaging bag through elastic pressure, effectively preventing misalignment of the sealing due to bag body displacement during the sealing process. The pre-tightening force of the spring 21 ensures that the extrusion cylinder 18 can form a stable constraint on packaging bags of different thicknesses, which not only avoids bag deformation that may be caused by rigid clamping, but also improves the consistency of the sealing position, providing a reliable positioning guarantee for subsequent sealing processes, thereby ensuring the stability and accuracy of the sealing process.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
