Description

Technical Field

[0001] This utility model relates to exhaust equipment, and more particularly to exhaust equipment for food packaging bags. Background Technology

[0002] Food packaging bags are thin-film containers that come into direct contact with food and are used to hold and protect it. Their main purpose is to protect food from damage and spoilage, contain food during transportation and storage, and provide consumers with information on ingredients and nutrition. Food packaging bags are typically made of plastic materials such as polyethylene and polypropylene, as well as polyester and nylon. These materials should be produced using food-grade plastic films. They are generally composite packaging bags with two or more layers. Before sealing, food packaging bags need to be vented to reduce their volume.

[0003] Patent CN217375131U discloses a sealing and venting device for food packaging bags, including a workbench, a conveyor belt arranged along the length of the workbench, a mounting frame fixedly installed at one end of the upper surface of the workbench, and a collection box placed on the side of the workbench near the mounting frame. The mounting frame has an inverted U-shaped structure, and one end of the conveyor belt extends into the mounting frame. Although the above patent can vent the packaging bag during sealing, reducing the volume of the packaging bag, it still has shortcomings in practical use. For example, when venting the packaging bag, the first cylinder is controlled to move downward to press the packaging bag to complete the venting. However, when the first cylinder is manually controlled, it is impossible to ensure that the pressing plate presses the packaging bag with appropriate force, which can easily damage the food inside the packaging bag and destroy the integrity of the food structure.

[0004] Therefore, there is a particular need for exhaust devices for food packaging bags to address the problems existing in the current technology. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents where the pressure plate cannot be guaranteed to press the packaging bag with appropriate force when the first cylinder is manually controlled, which can easily damage the food inside the packaging bag and destroy the integrity of the food, this utility model provides a food packaging bag exhaust device.

[0006] This utility model is achieved through the following technical means: a food packaging bag exhaust device, including a support frame, a rotating plate, motor I, a support plate, motor II, a screw, clamping plates, a support rod, a cylinder, a sliding plate, an air pump, and an exhaust pipe. The rotating plate is rotatably connected to the upper part of the support frame, and motor I is mounted on the upper part of the support frame. The output shaft of motor I is fixedly connected to the rotating plate. A support plate is fixedly connected to the edge of the rotating plate. Small motors II are symmetrically distributed on the top of the support plate. A screw is connected to the output shaft of motor II via a coupling. Clamping plates are symmetrically distributed and slidably connected to the external threads of the screw. The clamping plates are slidably connected to the support plate. The right side of the support frame is connected via... A support rod is fixedly connected to the connecting plate. A cylinder is installed on the upper end of the support rod. A sliding plate is fixedly connected to the telescopic rod of the cylinder. A vacuum pump is installed on the left side of the sliding plate through an mounting ring. A vacuum pipe is connected to the lower part of the vacuum pump through a coupling. The support plate has a round hole for accommodating the vacuum pipe. Each vacuum pipe is located in the middle of every four clamping plates. The operation of motor I causes the rotating plate to drive the support plate, motor II, and screw to rotate. The operation of motor II then causes the screw to rotate, which in turn causes the clamping plates to move inward. Finally, by controlling the extension or retraction of the telescopic rod of the cylinder, the sliding plate drives the vacuum pump to move downward or upward.

[0007] In a preferred embodiment of this utility model, the bottom surface of the clamp and the top surface of the sealer are on the same horizontal plane, so that the sealer accurately seals the opening of the food packaging bag.

[0008] In a preferred embodiment of this utility model, it further includes an electric slide rail, an electric slider, and a sealing device. An electric slide rail is fixedly connected to the outer side of the middle end of the support rod. Two electric sliders are slidably connected inside the electric slide rail. A sealing device for sealing food packaging bags is installed on the upper part of the electric slider. By controlling the electric slider to move inward or outward, the sealing device is driven to move inward or outward.

[0009] In a preferred embodiment of the present invention, an anti-slip pad is also included, and an anti-slip pad for increasing friction is connected to the clamping surface of the clamping plate.

[0010] In a preferred embodiment of the present invention, the anti-slip mat is made of rubber, and the surface of the anti-slip mat is provided with rubber hemispheres arranged in a rectangular array.

[0011] In a preferred embodiment of the present invention, a guide rod I is further included. The guide rods I are symmetrically distributed and fixedly connected inside the support plate, and the two clamping plates slide between the outside of the two guide rods I.

[0012] In a preferred embodiment of the present invention, a guide rod II is further included, the upper end of the support rod is fixedly connected to the guide rod II, and the sliding plate is slidably connected to the guide rod II.

[0013] Based on the above description of the structure of this utility model, the design starting point, concept, and advantages of this utility model are as follows: 1. By setting up a cylinder, a sliding plate, a vacuum pump, and a vacuum pipe, the cylinder is turned on, and the extension rod of the cylinder is controlled to extend to a suitable length, thereby causing the sliding plate to drive the vacuum pump to move downward, so that the vacuum pipe is inserted into the opening of the food packaging bag. The vacuum pipe does not come into contact with the food inside the food packaging bag. Then the vacuum pump is turned on again, so that the vacuum pipe extracts the gas inside the food packaging bag, thereby achieving a simple and fast exhaust effect, effectively solving the problem that existing packaging bags are prone to crushing the food inside and damaging its integrity structure.

[0014] 2. By setting up motor I, turning on motor I causes the rotating plate to rotate 45 degrees, thereby causing the food packaging bags that have been vented and sealed to be staggered from the air pump, so that the next food packaging bag to be vented and sealed is aligned with the air pump, thus achieving the effect of continuous venting and sealing of multiple food packaging bags, improving the venting and sealing efficiency of food packaging bags.

[0022] Example: Exhaust device for food packaging bags, see reference. Figures 1-5As shown, the device includes a support frame 1, a rotating plate 101, a motor I 2, a support plate 3, a motor II 4, a screw 5, a clamping plate 6, an anti-slip pad 7, a guide rod I 8, a support rod 9, a cylinder 10, a sliding plate 11, an air pump 12, a guide rod II 13, an air extraction pipe 14, an electric slide rail 15, an electric slider 1501, and a sealing device 16. The rotating plate 101 is rotatably connected to the upper part of the support frame 1. The motor I 2 is bolted to the upper part of the support frame 1. The output shaft of the motor I 2 is fixedly connected to the rotating plate 101. The support plate 3 is welded to the edge of the rotating plate 101. Small motors II 4 are symmetrically distributed on the top of the support plate 3 by bolts. A screw 5 is connected to the output shaft of motor II4 via a coupling. Symmetrically distributed clamping plates 6 are threaded onto the external surface of screw 5. The bottom surface of clamping plates 6 is on the same horizontal plane as the top surface of sealing device 16, allowing sealing device 16 to accurately seal the opening of the food packaging bag. Clamping plates 6 are slidably connected to support plate 3. Anti-slip pads 7, made of rubber, are attached to the clamping surface of clamping plates 6 to increase friction. The surface of anti-slip pads 7 has rubber hemispheres arranged in a rectangular array. Symmetrically distributed guide rods I8 are welded inside support plate 3. Each pair of clamping plates 6 slides between each pair of guide rods I8, improving the stability of the clamping plate 6's movement. The right side of support frame 1 is welded... A support rod 9 is connected by a bolt, and a cylinder 10 is bolted to the upper end of the support rod 9. A sliding plate 11 is welded to the telescopic rod of the cylinder 10. A vacuum pump 12 is bolted to the left side of the sliding plate 11 via a mounting ring. A guide rod II 13 is welded to the upper end of the support rod 9. The sliding plate 11 and the guide rod II 13 are slidably connected, which improves the smoothness of the movement of the sliding plate 11. A vacuum pipe 14 is connected to the lower part of the vacuum pump 12 via a coupling. The support plate 3 has a round hole for accommodating the vacuum pipe 14, and each vacuum pipe 14 is located in the middle of every four clamping plates 6. The middle part of the support rod 9 is welded to the outside of the square... The device is connected to an electric slide rail 15, which has two electric sliders 1501 slidably connected inside. The upper part of the electric sliders 1501 is connected to a sealing device 16 for sealing food packaging bags by bolts. The motor I2 runs, which in turn causes the rotating plate 101 to drive the support plate 3, motor II 4 and screw 5 to rotate. The motor II 4 runs, which causes the screw 5 to rotate, which in turn causes the clamping plate 6 to move inward. The extension or retraction of the telescopic rod of the control cylinder 10 causes the sliding plate 11 to drive the air pump 12 to move down or up. Finally, the electric sliders 1501 are controlled to move inward or outward, which in turn causes the sealing device 16 to move inward or outward.

[0023] First, the staff places the opening of the food packaging bag between the four corresponding clamps 6, and pre-pinch the opening of the food packaging bag to open it. Then, the two adjacent motors II4 are turned on in sequence. The output shaft of motor II4 rotates, driving the screw 5 to rotate, which in turn causes the four corresponding clamps 6 to move inward synchronously to clamp the food packaging bag. After clamping, the cylinder 10 is turned on, and the telescopic rod of the cylinder 10 is extended to a suitable length, which causes the sliding plate 11 to drive the vacuum pump 12 to move downward, so that the vacuum pipe 14 is inserted into the opening of the food packaging bag. Then, the vacuum pump 12 is turned on, and the operation of the vacuum pump 12 causes the vacuum pipe 14 to extract the gas from the food packaging bag, thereby realizing the venting of the food packaging bag. After venting is completed, the telescopic rod of the cylinder 10 is retracted, which causes the sliding plate 11 to drive the vacuum pump 12 to move upward, so that the vacuum pipe 14 is pulled out from the opening of the food packaging bag. Then, the electric slide rail 15 is turned on. The sealing device 16 controls the corresponding two electric sliders 1501 to move inward, thereby driving the two sealing devices 16 to move inward synchronously to seal the food packaging bag. After sealing, the electric sliders 1501 are controlled to move outward, thereby driving the two sealing devices 16 to move outward synchronously to loosen the food packaging bag. Then, the motor I2 is turned on, and the output shaft of the motor I2 rotates, driving the rotating plate 101 to rotate. The rotating plate 101 drives the support plate 3, motor II 4, screw 5, and clamping plate 6 to rotate. When the rotating plate 101 rotates 45 degrees, the motor I2 is turned off, thereby causing the food packaging bag that has been vented and sealed to be staggered from the vacuum pump 12, so that the next food packaging bag to be vented and sealed is aligned with the vacuum pump 12. The above operation is repeated to vent and seal the next food packaging bag, thereby achieving the effect of continuous venting and sealing of multiple food packaging bags and improving the venting and sealing efficiency of food packaging bags.
