Description

Technical Field

[0001] The present invention relates to the field of food processing, and particularly to a food packaging device for food processing. Background Art

[0002] Food packaging devices for food processing are mainly used to package and seal various foods to ensure the freshness, hygiene, safety, and quality maintenance of foods during production, transportation, and sales. Foods can be hermetically packaged to prevent the intrusion of external factors such as air, moisture, and bacteria, thereby extending the freshness period of foods, slowing down the rate of food spoilage, and maintaining the freshness and taste of foods.

[0003] When the current continuous vacuum sealer is in use, when evacuating and packaging a food-filled packaging bag, it is necessary to manually pinch the mouth side of the packaging bag, and then make the bag mouth open by squeezing with both hands, and then insert the evacuation vacuum tube into the bag for evacuation. Then, through the conveyance of the conveyor, the packaging bag is heat-sealed by the sealer. The manual operation method has low efficiency, and since the vacuum tube is directly inserted into the packaging bag, there is a certain gap between the vacuum tube and the packaging bag during the process of withdrawing after evacuation. If the sealer cannot seal quickly in time, it will cause the problem of back-sucking external air into the packaging bag, thereby reducing the vacuum degree after sealing. Summary of the Invention

[0004] The purpose of the present invention is to provide a food packaging device for food processing to solve the problems of low efficiency of manual packaging and easy back-sucking.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions: It includes a continuous vacuum sealer and a conveyor. The conveyor includes multiple conveyor belts and a correction belt. The conveyor belts and the correction belt are arranged at intervals in sequence. The conveying directions of the conveyor belts and the correction belt are opposite. Multiple baffles are fixed on the conveyor belts, and a placement area is formed between two columns of baffles;

[0006] It further includes a bag mouth folding component. The bag mouth folding component includes a vertical plate fixed on one side of the conveyor and close to the continuous vacuum sealer and a folding unit. The folding unit has a folding channel parallel to and lower than the upper edge of the vertical plate, and there is a gap between the folding unit and the vertical plate;

[0007] The packaging bag is placed in the placement area with the bag mouth side pressed against the side of the vertical plate. The packaging bag is conveyed by the conveyor belt and is rubbed by the correction belt with the reverse conveying direction against one side of the baffle to complete correction. The bag mouth side of the packaging bag is folded by the folding unit, so that the bag mouth side is folded to the gap through the vertical plate and then passes through the folding channel so that the bag mouth faces the continuous vacuum sealer.

[0008] As a further description of the above technical solution: The conveyor belt further includes a driving roller and a driven roller;

[0009] A plurality of wheel grooves are reserved at intervals on both the driving roller and the driven roller. A first driven wheel is rotatably arranged in the wheel groove of the driving roller, and a second driven wheel is rotatably arranged in the wheel groove of the driven roller. The conveyor belt is driven by the driving roller and the second driven wheel, and the correction belt is driven by the driven roller and the first driven wheel;

[0010] The driving roller and the driven roller are driven by a transmission unit.

[0011] As a further description of the above technical solution: The transmission unit includes a synchronous pulley and a synchronous belt. The driving roller is coaxially fixed with the synchronous pulley, and a synchronous pulley is rotatably connected to the shaft on one side of the conveyor near the driven roller;

[0012] The driven roller is coaxially fixed with a driven gear, and the driven gear meshes with a driving gear coaxially fixed with the synchronous pulley.

[0013] As a further description of the above technical solution: The folding unit includes an upper pressing rod and a dialing rod. The upper pressing rod is suspended and fixed on the frame of the conveyor by a support frame. A dialing rod is fixed near the conveying end of the conveyor belt, and the dialing rod is arranged crosswise with the vertical plate.

[0014] As a further description of the above technical solution: A lower support rod is fixed on the frame of the conveyor and is located below the upper pressing rod. Both the upper pressing rod and the lower support rod are tubular structures, and a plurality of suction holes are provided on the opposite sides. The upper pressing rod and the lower support rod are fixedly connected by a connecting pipe with a valve.

[0015] As a further description of the above technical solution: A plurality of convex strips are fixed on the outer surface of the correction belt.

[0016] As a further description of the above technical solution: A limiting plate is fixed on the advancing side of the baffle, and the limiting plate is a V-shaped structure with an opening facing the advancing side.

[0017] As a further description of the above technical solution: The driving gear is larger than the driven gear.

[0018] As a further description of the above technical solution: One end of the upper pressing rod near the dialing rod is a slope structure.

[0019] As a further description of the above technical solution: A plurality of transverse teeth are equidistantly distributed on the inner surfaces of the conveyor belt and the correction belt, and tooth grooves corresponding to the transverse teeth are provided on the driving roller, the driven roller, the first driven wheel, and the second driven wheel.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] As Figure 1 - Figure 10 shown, the present invention provides a food packaging device for food processing, including a continuous vacuum sealer 10 and a conveyor 20. The conveyor 20 includes a plurality of conveyor belts 21 and correction belts 22, which are arranged at intervals in sequence. The conveying directions of the conveyor belt 21 and the correction belt 22 are opposite. A plurality of baffles 23 are fixed on the conveyor belt 21, and a placement area is formed between two columns of baffles 23;

[0038] When the food packaging bag is placed in the placement area and the conveyor belt 21 is conveyed forward, the correction belt 22 is conveyed backward. Therefore, when the packaging bag is placed obliquely in the placement area, through the backward conveyance of the correction belt 22 and the friction with the packaging bag, the packaging bag moves toward the rear baffle 23 in the moving direction. After the edge side abuts against the baffle 23, the correction of the packaging bag can be completed. Furthermore, the bag mouth can face the vacuum tube 11 side of the continuous vacuum sealer 10, and manual adjustment is not required, thereby improving the aesthetics after sealing. Through the combined action of the conveyor belt 21 and the baffle 23, the corrected packaging bag can be driven to move linearly;

[0039] It further includes a bag mouth folding assembly 30. The bag mouth folding assembly 30 includes a vertical plate 31 fixed on one side of the conveyor 20 and close to the continuous vacuum sealer 10 and a folding unit 32. The folding unit 32 has a folding channel parallel to and lower than the upper edge of the vertical plate 31, and there is a gap between the folding unit 32 and the vertical plate 31;

[0040] The packaging bag is placed in the placement area with the bag mouth side pressed against the side of the vertical plate 31. The packaging bag is conveyed by the conveyor belt 21 and rubbed by the correction belt 22 that conveys in the reverse direction against the baffle 23 on one side to complete the correction. The bag mouth side of the packaging bag is folded by the folding unit 32, so that the bag mouth side is folded to the gap through the vertical plate 31, and then through the folding channel, the bag mouth faces the continuous vacuum sealer 10;

[0041] The vertical plate 31 is fixed on the frame of the conveyor 20 and is parallel to the conveying direction. The packaging bag containing food is placed in the placement area, and the bag mouth side is pressed against the inner side of the vertical plate 31 (as Figure 4 shown). In this way, through the limit of the vertical plate 31, the bag mouth side of the packaging bag is turned upward, so as to avoid the food in the bag flowing out of the bag mouth. After the packaging bag moves linearly with the conveyor belt 21 and passes through the folding unit 32, the folding unit 32 folds the bag mouth side folded into an L shape downward into the gap of the folding unit 32. The bag mouth side forms an inverted V-shaped support state through the support of the vertical plate 31, and at this time the bag mouth faces the vacuum tube 11 through the folding channel. At this time, through multiple folds of the packaging bag by the vertical plate 31 and the folding unit 32, the sealing performance at the bag mouth is increased. Therefore, when the vacuum tube 11 is withdrawn after evacuating the air from the bag, the problem of the bag inhaling external gas back can be avoided.

[0042] As Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 shown, the conveyor belt 21 further includes a driving roller 24 and a driven roller 25;

[0043] Both the driving roller 24 and the driven roller 25 are provided with a plurality of wheel grooves at intervals. A first driven wheel 241 is rotatably arranged in the wheel groove of the driving roller 24, and a second driven wheel 251 is rotatably arranged in the wheel groove of the driven roller 25. The conveyor belt 21 is driven by the driving roller 24 and the second driven wheel 251, and the correction belt 22 is driven by the driven roller 25 and the first driven wheel 241. The first driven wheel 241 and the second driven wheel 251 are arranged in a staggered manner. Therefore, when the driving roller 24 rotates clockwise, at this time, the forward conveying of the conveyor belt 21 is realized through the driving roller 24 and the second driven wheel 251, and the driven roller 25 is driven to convey in the reverse direction through the transmission of the transmission unit 26, so that the correction belt 22 follows the driven roller 25 to convey in the reverse direction.

[0044] As Figure 3 、 Figure 4 、 Figure 9 shown, the transmission unit 26 includes a synchronous pulley 261 and a synchronous belt 262. The driving roller 24 is coaxially fixed with the synchronous pulley 261. One side of the frame of the conveyor 20 close to the driven roller 25 is rotatably connected with the synchronous pulley 261 through the cooperation of a shaft rod and a bearing. The two synchronous pulleys 261 are driven by the synchronous belt 262;

[0045] The driven roller 25 is coaxially fixed with a driven gear 264, and the driven gear 264 meshes with a driving gear 263 that is coaxially fixed with the synchronous pulley 261. Moreover, the driving gear 263 is away from the driving roller 24. Therefore, when the driving roller 24 rotates forward, the driving gear 263 realizes synchronous rotation through the transmission of the synchronous pulley 261 and the synchronous belt 262, and then realizes the reverse rotation of the driven roller 25 through the meshing of the driving gear 263 and the driven gear 264.

[0046] As Figure 5 、 Figure 6 As shown in the figure, the folding unit 32 includes an upper pressing rod 321 and a dial rod 324. The upper pressing rod 321 is suspended and fixed on the frame of the conveyor 20 through a support frame 33. A dial rod 324 is fixed at the conveying end of the upper pressing rod 321 close to the conveyor belt 21. The lower edge of the upper pressing rod 321 is lower than the upper edge of the vertical plate 31. At the same time, it is cross - arranged with the vertical plate 31 through the dial rod 324. When the bag mouth of the packaging bag abuts against the inner side of the vertical plate 31 and is turned up, the bag mouth is then placed on the side in the V - shaped opening formed by the vertical plate 31 and the dial rod 324. When the packaging bag moves along with the conveyor belt 21 and abuts against the dial rod 324, at this time, the dial rod 324 presses the side of the bag mouth towards the outside of the baffle 23, and through the guidance of the upper pressing rod 321, the side of the bag mouth is pressed inside the folding channel, so that the folding action of the side of the bag mouth can still be realized without manual intervention.

[0047] As Figure 5 As shown in the figure, a lower support rod 322 is fixed on the frame of the conveyor 20 and is located below the upper pressing rod 321. A folding channel is formed between the lower support rod 322 and the upper pressing rod 321. And through the tubular structure design of the upper pressing rod 321 and the lower support rod 322, and a plurality of suction holes 325 are opened on the opposite sides. The upper pressing rod 321 and the lower support rod 322 are of tubular structure and are fixedly connected by a connecting pipe 323 with a valve. The connecting pipe 323 is connected to a vacuum machine. Therefore, by pumping air in the connecting pipe 323 with the vacuum machine, the upper pressing rod 321 and the lower support rod 322 inhale air through the suction holes 325. Therefore, when the bag mouth of the packaging bag passes through the position of the suction holes 325, at this time, the bag mouth is unfolded up and down through the negative pressure adsorption effect to facilitate the insertion of the vacuum tube 11 into the bag;

[0048] It should be noted that the air pressure of the suction holes 325 can be adjusted through the valve of the connecting pipe 323 to ensure that the suction holes 325 can adsorb and open the packaging bag, and at the same time, it does not affect the normal conveying of the packaging bag.

[0049] As Figure 3 、 Figure 8As shown, a plurality of ridges 221 are fixed on the outer surface of the correction belt 22. When the vacuum packaging bag contains granular foods (such as soybeans, yellow soybeans, rice), when the correction belt 22 drives the ridges 221 to rotate cyclically, firstly, the ridges 221 ensure good contact between the correction belt 22 and the packaging bag. Secondly, when the ridges 221 pass through the bottom of the packaging bag, the granular foods in the packaging bag will be jolted up and down. After repeated jolting of the granular foods, the foods in the bag can be leveled.

[0050] As Figure 3 、 Figure 5 、 Figure 7 As shown, a limiting plate 231 is fixed on the advancing side of the baffle 23. The limiting plate 231 is a V-shaped structure with an opening facing the advancing side. When the packaging bag is reversely rubbed by the correction belt 22 and moves towards the limiting plate 231, through the V-shaped structure of the limiting plate 231, the packaging bag can be limited to prevent the edge side of the packaging bag from sliding upwards along the baffle 23 after being rubbed by the correction belt 22.

[0051] As Figure 3 As shown, through the structural design that the driving gear 263 is larger than the driven gear 264, the rotation speed of the driven roller 25 is greater than that of the driving roller 24. Furthermore, when the conveyor belt 21 is slowly conveyed, a fast reverse conveying force can be provided for the correction belt 22 to ensure the rapid correction of the packaging bag within a short distance.

[0052] One end of the upper pressing rod 321 close to the dial rod 324 is designed with a slope structure. After the dial rod 324 guides the bag mouth to turn over, through the slope structure on the lower edge of the upper pressing rod 321, it is convenient to guide the bag mouth side into the folding channel.

[0053] As Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 , by equally spacing and distributing a plurality of transverse teeth on the inner surfaces of the conveyor belt 21 and the correction belt 22, and the driving roller 24, the driven roller 25, the first driven wheel 241, and the second driven wheel 251 are provided with tooth grooves corresponding to the transverse teeth. Through the cooperation of the transverse teeth and the tooth grooves, it is ensured that each row of baffles 23 is always in a collinear state.

[0054] Working principle: Start the conveyor 20. The servo motor of the conveyor 20 drives the driving roller 24 to rotate through a chain and a sprocket, and the driven roller 25 rotates reversely through the transmission of the transmission unit 26;

[0055] Place the vacuum packaging bag containing food in the placement area and make the food part abut against the inner side of the vertical plate 31. When placing, the bag mouth side can be assisted to be pulled between the dial rod 324 and the vertical plate 31;

[0056] When the conveyor belt 21 is conveying the packaging bag and the food inside the bag forward, at this time, the correction belt 22 is conveyed reversely through the drive of the drive unit 26, and under the action of friction, the bottom of the edge of the packaging bag that does not abut against the baffle 23 swings under the reverse conveying action of the correction belt 22, and until the edge of the packaging bag abuts against the baffle 23, the correction of the packaging bag can be completed;

[0057] The corrected packaging bag passes through the combined action of the conveyor belt 21 and the baffle 23, so that the bag mouth side slides along the folding channel, and the suction hole 325 is placed at the vacuum tube 11. When the bag mouth side is placed at the suction hole 325, at this time, under the action of negative pressure adsorption, the bag mouth unfolds. At this time, the vacuum tube 11 is inserted into the bag to evacuate the air, and at the same time, the bag mouth side is placed in the sealing machine of the continuous vacuum sealing machine 10. At this time, the sealing machine seals the moving packaging bag.

[0058] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
