Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, specifically to a food pillow packaging machine. Background Technology

[0002] Pillow-type packaging machines are continuous packaging machines with very high packaging capacity, suitable for various sizes of food and non-food packaging. Pillow-type food packaging machines are widely used in the instant noodle, rice cracker, shrimp chip, French fry, rice cracker, egg roll, and puffed food industries, and also have wide applications in the daily chemical industry such as laundry detergent. They are suitable for packaging regularly shaped objects.

[0003] According to a public disclosure of a pillow-type packaging machine for food (publication number: CN2174036155U), it includes a first support, a second support, and a packaging machine body. The packaging machine body is fixed with a long plate, and a fixed plate is fixed to the rear end of the long plate. The front end of the fixed plate is movably connected to the first support. A hydraulic cylinder is fixed to the front end of the inner wall of the first groove. The front end of the hydraulic rod movably connected to the hydraulic cylinder passes through the first support. A movable plate is fixed to the front end of the hydraulic rod. The front sides of the movable plate are respectively movably connected to the second support. The front end of the second support has a circular hole and a first groove. The front end of the inner wall of the first groove is fixed with a third motor. The transmission shaft of the third motor extends into the circular hole, and a clamping plate is fixed to the front end of the transmission shaft of the third motor. This invention has the advantage of being able to limit the position of multiple food items, making them fit tightly together for easy packaging. However, in the above-mentioned device, the cooperation of components such as the first and second supports makes it difficult to achieve the effect of clamping and positioning the food and packaging bag when the food is pressurized and sealed, resulting in uneven sealing of the sealing opening and affecting the sealing performance. Therefore, we have specifically proposed a food pillow packaging machine for clamping food and packaging bags when sealing them. Utility Model Content

[0004] This utility model proposes a food pillow-type packaging machine that solves the problem in related technologies where a motor drives a rotating rod to rotate, thereby causing the rotating rod to rotate a long plate, which in turn causes the long plate to drive a short rod A on it to move in a circular motion, which in turn causes the short rod A to drive a connecting plate to move in a circular motion, which in turn causes the connecting plate to push the short rod B to move horizontally, which in turn causes the short rod B to drive the positioning frame to move horizontally, which in turn causes the positioning frame to drive the clamping plate to move horizontally.

[0005] The technical solution of this utility model is as follows: A food pillow packaging machine includes a sealing device, the sealing device includes a worktable, an anti-slip pad is fixedly connected to the bottom of the worktable, a fixed frame is fixedly connected to the top of the worktable, a hydraulic component is provided on the top of the fixed frame, a pressure block is fixedly connected to the end of the hydraulic rod away from the hydraulic cylinder, a groove is provided on the top of the worktable, and a rectangular groove is provided on the inner wall of the groove.

[0006] The sealing device is equipped with a clamping device, which includes a motor. The motor is fixedly connected to the inner wall of the rectangular groove. The output shaft of the motor is fixedly connected to a rotating rod. The end of the rotating rod away from the motor passes through a long plate and is fixedly connected to the long plate. One end of the long plate passes through a short rod A and is fixedly connected to the short rod A. The end of the short rod A away from the long plate passes through a connecting plate and is rotatably connected to the connecting plate. The end of the connecting plate away from the short rod A passes through a short rod B and is rotatably connected to the short rod B. The end of the short rod B away from the connecting plate is fixedly connected to a positioning frame. The end of the positioning frame away from the short rod B is fixedly connected to a clamping plate. The bottom of the positioning frame has a sliding groove. The inner wall of the groove is fixedly connected to a sliding rod on the side near the rectangular groove. The inner wall of the groove is fixedly connected to a top cover. The top cover has a through groove.

[0007] Furthermore, the number of anti-slip pads is four, arranged in pairs and symmetrical to each other along the vertical central axis of the workbench. The shape of the pressure block is U-shaped. The hydraulic rod in the hydraulic assembly passes through the fixed frame and is slidably connected to the fixed frame. The above design helps to ensure the stability of the device during operation through four anti-slip pads.

[0008] Furthermore, there are two short rods A, which are symmetrical to each other along the vertical central axis of the long plate, and there are two connecting plates, which are symmetrical about the center point of the rotating rod. The above design is conducive to driving the two short rods A to perform circular motion through the long plate.

[0009] Furthermore, the sealing device is equipped with a lubrication device, which includes a push plate. One end of the push plate is fixedly connected to one side of the positioning frame, and a push rod is fixedly connected to one side of the push plate. An air bladder is fixedly connected to the inner wall of the groove, and a spring is fixedly connected to the inner wall of the air bladder. A connecting pipe is fixedly inserted through the circumference of the air bladder. A circular groove is formed on the side of the groove near the rectangular groove, and an oil tank is fixedly connected to the inner wall of the circular groove. The end of the connecting pipe away from the air bladder is fixedly inserted through the top of the oil tank. A spray pipe is fixedly inserted through the circumference of the air bladder. The above design is beneficial for lubricating the components in the device and increasing the service life of the device.

[0010] Furthermore, the airbag is made of rubber, and the airbag is located on the displacement trajectory of the push rod away from the push plate. The slide rod is located at the opening of the nozzle. The above design is conducive to squeezing the airbag by the push rod, so that the airbag is compressed by force.

[0011] Furthermore, the connecting tube is L-shaped, the push plate is located inside the groove, the push rod is located inside the groove, and the airbag is located below the top cover. This design helps to prevent the airbag from being restricted by the top cover when it is deformed by force.

[0012] Furthermore, there are two short rods B, which are symmetrical to each other along the vertical central axis of the rotating rod. The positioning frame is L-shaped, and there are two positioning frames, which are symmetrical to each other along the vertical central axis of the worktable. The above design is conducive to the horizontal displacement of the positioning frame by driving the short rods B.

[0013] Furthermore, there are two clamping plates, which are symmetrical to each other along the vertical central axis of the workbench. The end of the positioning frame near the clamping plate passes through the top cover through a slot and is slidably connected to the top cover. The above design is beneficial for holding the food and packaging bags to be packaged by the two clamping plates.

[0014] Furthermore, there are two slide rods, which are symmetrical to each other along the vertical central axis of the worktable. The side of the slide rod away from the groove is slidably connected to the inner wall of the groove. The above design is conducive to limiting the positioning frame through the mutual contact between the slide rod and the inner wall of the groove.

[0015] Furthermore, the top cover is H-shaped, the fixing frame is L-shaped, and the top of the top cover is located on the displacement trajectory of the pressure block. This design is beneficial for pressing the food and packaging bags placed on the top of the top cover by the pressure block.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] 1. In this utility model, the force of the motor-driven rotating rod, in conjunction with components such as the long plate, short rod A, and connecting plate, enables the motor to drive the rotating rod to rotate, thereby causing the rotating rod to drive the long plate to rotate. This, in turn, causes the long plate to drive the short rod A on it to rotate, which in turn causes the short rod A to rotate, which in turn causes the connecting plate to rotate. This, in turn, causes the connecting plate to push the short rod B to move horizontally, which in turn causes the short rod B to move horizontally, which in turn causes the positioning frame to move horizontally. This achieves the effect of clamping and positioning the food and packaging bag when pressurizing and sealing food, avoiding uneven sealing at the sealing opening, which would affect the sealing performance.

[0018] 2. In this utility model, the force of the positioning frame displacement, in conjunction with the push plate, push rod, and airbag components, enables the positioning frame to move horizontally, which in turn drives the push plate to move horizontally. This, in turn, causes the push plate to move horizontally, which in turn drives the push rod to move horizontally. Consequently, the push rod compresses the airbag, causing it to contract. When the push rod moves away from the airbag, the airbag, through the tension of its internal spring, draws oil from the oil tank into its interior via the connecting pipe. When the push rod compresses the airbag again, the airbag drips oil onto the slide rod through the spray pipe, thus lubricating the components of the device and increasing its service life.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1

[0028] like Figures 1-5 As shown, this embodiment proposes a food pillow packaging machine, including a sealing device 1. The sealing device 1 includes a workbench 101. An anti-slip pad 102 is fixedly connected to the bottom of the workbench 101. A fixed frame 103 is fixedly connected to the top of the workbench 101. A hydraulic component 104 is provided on the top of the fixed frame 103. A pressure block 105 is fixedly connected to the end of the hydraulic rod away from the hydraulic cylinder. A groove 106 is opened on the top of the workbench 101. A rectangular groove 107 is opened on the inner wall of the groove 106.

[0029] The sealing device 1 is internally equipped with a clamping device 2, which includes a motor 201. The motor 201 is fixedly connected to the inner wall of the rectangular groove 107. The output shaft of the motor 201 is fixedly connected to a rotating rod 202. The end of the rotating rod 202 away from the motor 201 passes through a long plate 203 and is fixedly connected to the long plate 203. One end of the long plate 203 passes through a short rod A204 and is fixedly connected to the short rod A204. The end of the short rod A204 away from the long plate 203 passes through a connecting plate 205 and is rotatably connected to the connecting plate 205. The end of the connecting plate 205 away from the short rod A204 is connected to the short rod B206 and is rotatably connected to the short rod B206. The end of the short rod B206 away from the connecting plate 205 is fixedly connected to the positioning frame 207. The end of the positioning frame 207 away from the short rod B206 is fixedly connected to the clamping plate 208. The bottom of the positioning frame 207 is provided with a sliding groove 209. The inner wall of the groove 106 is fixedly connected to the side of the rectangular groove 107. The inner wall of the groove 106 is fixedly connected to the top cover 211. The top of the top cover 211 is provided with a through groove 212.

[0030] There are four anti-slip pads 102, arranged in pairs and symmetrical to each other along the vertical central axis of the workbench 101. The pressure block 105 is U-shaped. The hydraulic rod in the hydraulic assembly 104 passes through the fixed frame 103 and is slidably connected to the fixed frame 103. The above design helps to ensure the stability of the device during operation through the four anti-slip pads 102.

[0031] There are two short rods A204, which are symmetrical to each other along the vertical central axis of the long plate 203. There are two connecting plates 205, which are symmetrical about the center point of the rotating rod 202. The above design is conducive to driving the two short rods A204 to perform circular motion through the long plate 203.

[0032] In this embodiment, the motor 201 drives the rotating rod 202 to rotate, which in turn drives the long plate 203 to rotate. This causes the long plate 203 to drive the short rod A204 on it to rotate in a circular motion. The short rod A204 then drives the connecting plate 205 to rotate in a circular motion. This causes the connecting plate 205 to push the short rod B206 to move horizontally. This causes the short rod B206 to move the positioning frame 207 horizontally, which in turn moves the clamping plate 208 horizontally. This achieves the effect of clamping and positioning the food and packaging bag when pressurizing and sealing the food, avoiding uneven sealing of the sealing opening and thus affecting the sealing performance.

[0033] Example 2

[0034] like Figures 1-5As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a food pillow packaging machine, including a sealing device 1. The sealing device 1 is equipped with a lubrication device 3. The lubrication device 3 includes a push plate 301. One end of the push plate 301 is fixedly connected to one side of the positioning frame 207. A push rod 302 is fixedly connected to one side of the push plate 301. An air bladder 303 is fixedly connected to the inner wall of the groove 106. A spring 304 is fixedly connected to the inner wall of the air bladder 303. A connecting pipe 305 is fixedly passed through the circumferential surface of the air bladder 303. A circular groove 307 is opened on the side of the groove 106 near the rectangular groove 107. An oil tank 306 is fixedly connected to the inner wall of the circular groove 307. The end of the connecting pipe 305 away from the air bladder 303 is fixedly passed through the top of the oil tank 306. A spray pipe 308 is fixedly passed through the circumferential surface of the air bladder 303. The above design is beneficial for lubricating the components in the device and increasing the service life of the device.

[0035] The airbag 303 is made of rubber. The airbag 303 is located on the displacement trajectory of the push rod 302 away from the push plate 301. The slide rod 210 is located at the opening direction of the nozzle 308. The above design is conducive to squeezing the airbag 303 by the push rod 302, so that the airbag 303 is compressed by force.

[0036] The connecting tube 305 is L-shaped, the push plate 301 is located inside the groove 106, the push rod 302 is located inside the groove 106, and the airbag 303 is located below the top cover 211. The above design helps to prevent the airbag 303 from being restricted by the top cover 211 when it is deformed by force.

[0037] There are two short rods B206, which are symmetrical to each other along the vertical central axis of the rotating rod 202. The positioning frame 207 is L-shaped, and there are two positioning frames 207, which are symmetrical to each other along the vertical central axis of the worktable 101. The above design is conducive to driving the positioning frame 206 to make horizontal displacement through the short rods B206.

[0038] There are two clamping plates 208, which are symmetrical to each other along the vertical central axis of the workbench 101. The end of the positioning frame 207 near the clamping plate 208 passes through the top cover 211 through the through groove 212 and is slidably connected to the top cover 211. The above design is conducive to holding the food and packaging bags that need to be packaged by the two clamping plates 208.

[0039] There are two slide rods 210, which are symmetrical to each other along the vertical central axis of the worktable 101. The side of the slide rod 210 away from the groove 106 is slidably connected to the inner wall of the slide groove 209. The above design is conducive to limiting the positioning frame 207 through the mutual contact between the slide rod 210 and the inner wall of the slide groove 209.

[0040] The top cover 211 is H-shaped, the fixing bracket 103 is L-shaped, and the top of the top cover 211 is located on the displacement trajectory of the pressure block 105. The above design is beneficial for the food and packaging bags placed on the top of the top cover 211 to be squeezed by the pressure block 105.

[0041] In this embodiment, when the positioning frame 207 moves horizontally, it causes the push plate 301 to move horizontally, which in turn causes the push plate 301 to move the push rod 302 horizontally. This causes the push rod 302 to compress the airbag 303, causing the airbag 303 to contract under force. When the push rod 302 moves away from the airbag 303, the airbag 303, under the tension of the internal spring 304, draws oil from the oil tank 306 into the airbag 303 through the connecting pipe 305. When the push rod 302 compresses the airbag 303 again, the airbag 303 drips oil onto the slide rod 210 through the spray pipe 308, achieving the effect of lubricating the components in the device and increasing the service life of the device.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
