Description

Technical Field

[0001] The invention relates to the technical field of food film pasting, in particular to automatic film pasting equipment for food production. Background Art

[0002] Food film laminating equipment is a kind of equipment used in the food processing industry. It refers to the equipment that laminates food during the processing process. Laminating food can prevent dust, moisture, oxidation and preserve food, which is beneficial to ensure the quality of food and extend the shelf life of food. In addition, most of the existing films are made of environmentally friendly materials, which can reduce harm to the environment while ensuring food quality.

[0003] Chinese patent CN105015806B discloses an edible fungus food production line, including a frame, a movable track on the frame, a cup-dropping device for delivering the cup body to the placement slot at the starting end on the right side of the frame, a loading device for loading into the cup body on the left side of the cup-dropping device, a liquid injection device for injecting liquid into the cup body on the left side of the loading device, and a film sealing device for sealing the port of the cup body on the left side of the liquid injection device. The edible fungus food production line of the invention will automatically enter the movable track for the cup body for placing edible fungi without manual operation, and complete a series of steps such as material unloading, liquid injection preservation and packaging in sequence until the final shipment packaging, which improves work efficiency and saves time. Moreover, the edible fungi are sterilized and cleaned before unloading and packaging, which is hygienic and environmentally friendly. No human hands are used in the process. The use of liquid preservation makes the edible fungi more delicious, and it also eliminates the soaking time. It is easy to use and worth promoting.

[0004] At present, when applying film to food, the film-applying devices in the prior art mostly use a vacuum adsorption film and then stick the film on the food. However, during the process of vacuum adsorption of the film, if the film is damaged, the vacuum degree will be reduced, and then the film will fall off from the vacuum adsorption component or shift on the vacuum adsorption component. When the film falls off from the vacuum adsorption component, it will hit the nearby food that has been pasted with the film, and then the pasted film will be distorted, which is not conducive to subsequent heat sealing. If the film is displaced on the vacuum adsorption component, the problem of inaccurate film-applying position will also occur, which is still not conducive to subsequent heat sealing operations.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In order to solve the technical problem that when the film is damaged during the vacuum adsorption process, the vacuum degree will be reduced, and the film will fall off from the vacuum adsorption component 10 or move on the vacuum adsorption component 10, such as Figure 1 - Fig. 9 As shown, the following preferred technical solutions are provided:

[0032] An automatic film-sticking device for food production includes a plurality of legs 1 arranged on the ground, a mounting frame 2 is fixedly arranged on the upper ends of the plurality of legs 1, the legs 1 play a role of supporting and fixing the mounting frame 2, a conveyor belt 3 is arranged inside the mounting frame 2, a plurality of placement boxes 4 are fixedly arranged on the outer wall of the conveyor belt 3, the conveyor belt 3 drives the placement boxes 4 to move forward at a uniform speed, and the food is placed inside the placement box 4 and is transported forward together with the conveyor belt 3, a plurality of drive components 5 are fixedly arranged on one side of the conveyor belt 3, and the output end of the drive component 5 It is fixedly connected to the rotating shaft on the conveyor belt 3, and the driving component 5 is used to provide power output, thereby being able to drive the conveyor belt 3 to rotate at a uniform speed. A heat sealing component 6 is fixedly arranged on the mounting frame 2. When the placement box 4 is conveyed to the specified position, the placement box 4 will be affixed with a film. After affixing the film, the placement box 4 will continue to move forward with the conveyor belt 3. When it reaches the position of the heat sealing component 6, the heat sealing component 6 heats the film on the placement box 4 so that the film sticks to the placement box 4, achieving the effect of heat sealing, and finally sealing the food inside the placement box 4 to achieve the effect of preserving the food.

[0033] A film cutting component 7 is arranged above the conveyor belt 3, which is used to cut the whole piece of film into suitable length and corresponding shape. A film pressing component 8 is fixedly arranged on the film cutting component 7, which is used to compact the cut pieces of film, so as to facilitate the subsequent vacuum adsorption of the cut films. A flipping component 9 is also fixedly arranged on the mounting frame 2, and a plurality of vacuum adsorption components 10 are arranged on the flipping component 9. The vacuum adsorption component 10 adsorbs the cut film, and then the flipping component 9 drives the vacuum adsorption component 10 and the adsorbed film to flip 180° together, and then the adsorbed film is placed on the placing box 4, and then the flipping component 9 drives the vacuum adsorption component 10 to flip 180° in the opposite direction and adsorb the cut film again. In this way, continuous film sticking operation can be realized. Collecting components 20 are fixedly installed on the two opposite side walls of the mounting frame 2, and the two collecting components 20 are arranged in symmetrical positions.

[0034] When the film is damaged, the vacuum degree of the vacuum adsorption component 10 will decrease when adsorbing the film, which will cause the film to fall off the vacuum adsorption component 10 or move on the vacuum adsorption component 10. When the above situation occurs, the two collecting components 20 are started to operate synchronously, and then the vacuum adsorption component 10 is driven to flip to an appropriate angle through the flipping component 9. During the flipping process, if the vacuum degree is not enough, when the film falls off the vacuum adsorption component 10, it will directly fall into the collecting component 20 and will not hit the nearby placement box 4 with the film already affixed, thereby preventing the nearby affixed film from being distorted, which is beneficial to the subsequent heat sealing operation. If the vacuum degree is not enough during the flipping process and the film is displaced on the vacuum adsorption component 10, after flipping to an appropriate angle, the vacuum degree in the vacuum adsorption component 10 is canceled, and the film falls into the collecting component 20 under the action of gravity for collection.

[0035] The driving assembly 5 includes a base 51, on the top surface of which a servo motor 52 is fixedly mounted. The output end of the servo motor 52 is fixedly connected to the rotating shaft on the conveyor belt 3, and the servo motor 52 drives the conveyor belt 3 to rotate at a uniform speed.

[0036] The film cutting assembly 7 includes a conveyor belt 2 71, a servo motor 2 76 is fixedly installed on the side wall of the outer shell of the conveyor belt 2 71, and the output end of the servo motor 2 76 is fixedly connected to the shaft on the conveyor belt 2 71. The uncut film is placed on the conveyor belt 2 71, and the servo motor 2 76 provides power output to drive the conveyor belt 2 71 to rotate at a uniform speed. A support bracket 72 is fixedly installed on the outer shell of the conveyor belt 2 71, and an electric telescopic column 1 73 is fixedly installed on the top surface of the support bracket 72. The output end of the electric telescopic column 1 73 passes through the top of the support bracket 72, and a connecting plate 1 74 is fixedly installed on the output end of the electric telescopic column 1 73, and a plurality of cutters 75 are fixedly installed on the bottom surface of the connecting plate 1 74. The film is conveyed along the conveyor belt 2 71. When the photoelectric sensing system (the photoelectric sensing system is a well-known prior art and will not be described in detail here) determines that the film has reached a suitable position, the servo motor 2 76 stops rotating, and the conveyor belt 2 71 also stops rotating, and the electric telescopic column 1 73 is started. The electric telescopic column 1 73 drives the cutter 75 to move downward through the connecting plate 1 74 to cut the film on the conveyor belt 2 71. After the cutting is completed, the electric telescopic column 1 73 drives the cutter 75 to reset through the connecting plate 1 74, and the servo motor 2 76 continues to drive the conveyor belt 2 71 to rotate, and the cut film continues to be conveyed until it is transferred to the position where the vacuum adsorption component 10 can adsorb the film.

[0037] The flip assembly 9 includes a U-shaped frame 91 fixedly mounted on the side wall of the mounting frame 2, a pair of electric telescopic columns 92 are fixedly mounted on the top surface of the U-shaped frame 91, the output ends of the two electric telescopic columns 92 both pass through the top of the U-shaped frame 91, a roller 93 is rotatably arranged in the inner circle of the U-shaped frame 91, and connecting shafts 94 are fixedly connected to the side walls at both ends of the roller 93, the output ends of the two electric telescopic columns 92 are respectively correspondingly sleeved on the circumferential outer walls of the two connecting shafts 94, and the outer side walls of the two connecting shafts 94 are respectively fixedly connected to gears 1 95.

[0038] The U-shaped frame 91 includes a frame body 911, and mounting grooves 912 are respectively provided on two opposite side walls of the inner circle of the frame body 911, and racks 913 are respectively fixedly installed on the inner walls of one side of the inner cavity of the two mounting grooves 912. Gear 1 95 is rotatably set in the inner cavity of the mounting groove 912, and gear 1 95 is meshingly connected with the rack 913. A plurality of storage bins 914 are provided on the top surface of the frame body 911, and the conveyor belt 2 71 will convey the cut film to the storage bin 914 for storage. The vacuum adsorption component 10 adsorbs the cut film from the storage bin 914 to apply the film to the food, and a plurality of reset plates 915 are respectively fixedly installed on the outer walls on both sides of the top of the frame body 911 for resetting the vacuum adsorption component 10.

[0039] The vacuum adsorption component 10 includes a servo motor 3 101 fixedly mounted on the side wall of the roller 93 and a gear 2 102 fixedly connected to the output end of the servo motor 3 101. The roller 93 is provided with a rotating sleeve with a gear 3 103, and the gear 3 103 is meshed with the gear 2 102. The servo motor 3 101 can drive the gear 3 103, the adsorption piece 1 105, the adsorption piece 2 104 and the suction cup 106 to flip through the gear 2 102, and the adsorption piece 1 105 and the adsorption piece 2 104 are fixedly mounted on the circumferential outer wall of the gear 3 103, respectively. Adsorption component 1 105 and adsorption component 2 104 are symmetrically arranged, and reset plate 915 assists in resetting adsorption component 1 105 and adsorption component 2 104. The distal ends of adsorption component 1 105 and adsorption component 2 104 are respectively connected to and fixed with suction cups 106, and the shape of suction cups 106 matches the shape of the film cut. Adsorption component 1 105 and adsorption component 2 104 are externally connected with vacuum pumping equipment, so that negative pressure can be generated inside adsorption component 1 105, adsorption component 2 104 and suction cups 106, thereby realizing adsorption and release of the film, and finally realizing the cyclic film sticking operation.

[0040] The film pressing assembly 8 includes a connecting plate 81, which is fixedly connected to the connecting plate 1 74 by a plurality of connecting rods 82. A plurality of pressing plates 83 are fixedly installed on the bottom surface of the connecting plate 81. The conveyor belt 71 will convey the cut film to the storage bin 914 for storage, and then cut the subsequent film again. When the electric telescopic column 1 73 drives the cutter 75 to move downward through the connecting plate 1 74 to cut the film on the conveyor belt 71, since the connecting plate 81 and the connecting plate 1 74 are fixedly connected by the connecting rod 82, the connecting plate 81 and the pressing plate 83 will move downward synchronously with the electric telescopic column 1 73, and compact the cut film stored in the storage bin 914, which is beneficial for the suction cup 106 to adsorb the film and prevent the suction cup 106 from failing to absorb the film.

[0041] Specifically, under normal working conditions, when applying film to the food in the placing box 4, first, the external vacuum equipment (the vacuum equipment belongs to the prior art and will not be described in detail) starts to work, so that the inside of the adsorption piece 2 104 and the suction cup 106 becomes a negative pressure state, and the cut film stored in the storage bin 914 is adsorbed, and then the two electric telescopic columns 2 92 are started to extend synchronously, driving the two connecting shafts 94 to move downward synchronously. Since the gear 1 95 is meshed with the rack 913, the two connecting shafts 94 will drive the roller 93 to flip during the downward movement. Until the roller 93 flips 180°, the two electric telescopic columns 2 92 stop extending and positioning synchronously, and then the external vacuum equipment will adsorb the adsorption piece 2 104 and the suction cup The internal vacuum of 106 is cancelled, and the film falls on the top opening of the placement box 4, thereby realizing the film sticking operation. When the adsorbent 104 and the suction cup 106 are sticking the film, the external vacuum equipment changes the interior of the adsorbent 105 and the suction cup 106 into a negative pressure state to adsorb the cut film stored in the storage bin 914. After the adsorbent 104 and the suction cup 106 have completed the film sticking, the two electric telescopic columns 92 retract synchronously, driving the rotating roller 93 to flip 180°, and the two electric telescopic columns 92 stop retracting and positioning synchronously. At this time, the adsorbent 105 and the suction cup 106 release the adsorbed film to realize the film sticking operation, and the adsorbent 104 and the suction cup 106 continue to adsorb the cut film, and continuous film sticking operation can be realized by repeating this process.

[0042] When the cut film is damaged and the vacuum degree of the adsorbent 2 104 and the suction cup 106 or the vacuum degree of the adsorbent 105 and the suction cup 106 is insufficient, the adsorbed film will fall off the suction cup 106 or move on the suction cup 106. At this time, the two electric telescopic columns 2 92 are not started, and the servo motor 2 76 stops rotating, so that the conveyor belt 2 71 stops rotating, and the cutter 75 stops cutting the film. The collecting component 20 is started first. When the collecting component 20 reaches the specified position, the servo motor 3 101 is started. The servo motor 3 101 drives the gear 3 103, the adsorbent 2 104, the adsorbent 1 105 and the suction cup 106 to flip to an appropriate angle through the gear 2 102. At this time, if the film on the suction cup 106 falls off, the fallen film will fall into the collecting component 20 to prevent the nearby film from being distorted, which is beneficial to the subsequent heat sealing operation. The film does not fall off, but when it moves on the suction cup 106, after flipping to a suitable angle, the vacuum degree of the suction piece 2 104 and the suction cup 106 or the vacuum degree of the suction piece 1 105 and the suction cup 106 is canceled, and the film falls into the collection component 20 for collection under the action of gravity, and then the servo motor 3 101 drives the gear 3 103, the suction piece 2 104, the suction piece 1 105 and the suction cup 106 to flip back to the original position through the gear 2 102, and the film is re-absorbed to continue the subsequent film sticking operation. The above operation can not only prevent the detached film from distorting the nearby already stuck film, but also judge the air tightness of the film before sticking. The film with poor air tightness directly falls into the collection component 20 for collection, which reduces the working pressure of the later stage for food air tightness detection and forms a double-channel air tightness detection process, which is beneficial to improving the quality of food.

[0043] In order to solve the problem that during the process of the sucker 106 releasing the film, the film in the gap between the sucker 106 and the placing box 4 is in free fall motion, and because the film is light, the film is prone to inaccurate fitting position during the free fall process, such as Figure 1 - Figure 3 and Figure 6 - Fig. 9 As shown, the following preferred technical solutions are provided:

[0044] The adsorbent 105 includes a first vacuum cylinder 1051 fixedly mounted on the outer circumferential wall of the gear 3 103, a pair of slide grooves 1052 are provided on the inner wall of the inner cavity of the first vacuum cylinder 1051, a second vacuum cylinder 1053 is slidably mounted in the inner cavity of the slide groove 1052, the second vacuum cylinder 1053 is elastically connected to the side wall of the slide groove 1052 by a spring 1054, an electronic gas valve 1055 is fixedly mounted on the upper end of the second vacuum cylinder 1053, and the second vacuum cylinder 1053 is connected to the first vacuum cylinder 1051 by the electronic gas valve 1055. A vacuum sensor 1056 is fixedly installed inside the second vacuum cylinder 1053 for monitoring the vacuum degree inside the second vacuum cylinder 1053 to determine whether the cut film is damaged or has poor airtightness. An air hole 1057 is opened on the side wall of the inner cavity of the first vacuum cylinder 1051, and an electronic gas valve 2 1058 is fixedly installed on the outer wall of the first vacuum cylinder 1051. The electronic gas valve 2 1058 is connected to the inner cavity of the first vacuum cylinder 1051 through the air hole 1057. The composition structure and connection method of the adsorption component 1 105 and the adsorption component 2 104 are consistent.

[0045] Specifically, when the film is adsorbed, the external vacuum equipment starts to work, and then the electronic gas valve 2 1058 and the electronic gas valve 1 1055 are opened, so that the interior of the first vacuum cylinder 1051, the second vacuum cylinder 1053 and the suction cup 106 become a vacuum state, and then the film is adsorbed by the suction cup 106. When the adsorption is completed, the electronic gas valve 1055 is closed to maintain the vacuum degree inside the second vacuum cylinder 1053 and the suction cup 106. At this time, the intact film will not fall off the suction cup 106 or move on the suction cup 106. The external vacuum equipment continues to increase the vacuum degree of the first vacuum cylinder 1051. As the vacuum degree continues to increase, the second vacuum cylinder 1053 will retract into the interior of the first vacuum cylinder 1051 and compress the spring 1054. When the roller 93 drives the suction cup 106 on the second vacuum cylinder 1053 to the film sticking position, the external vacuum equipment reduces the vacuum degree inside the first vacuum cylinder 1051 through the electronic gas valve 2 1058 When the film is pasted on the placing box 4, the electronic valve 1055 is opened to reduce the vacuum degree inside the second vacuum cylinder 1053 and the suction cup 106, and the film is released on the placing box 4 to complete the film pasting operation. After the film pasting is completed, the electronic valve 1055 is immediately closed, and the external vacuum pumping equipment starts to work, and reduces the vacuum degree inside the first vacuum cylinder 1051 through the electronic valve 2 1058. The second vacuum cylinder 1053 and the suction cup 106 will retract into the first vacuum cylinder 1051 again and compress the spring 1054 again. At this time, the suction cup 106 is away from the film, and when the roller 93 drives the suction cups 106 on the first vacuum cylinder 1051 and the second vacuum cylinder 1053 to rotate, they will not touch the film that has been pasted with the placing box 4, and thus will not distort the pasted film.

[0046] In the prior art, the film is applied in a flipping manner. When the suction cup 106 releases the film, there is a gap between the suction cup 106 and the placement box 4, which prevents the suction cup 106 from touching the film that has been attached to the placement box 4 during the flipping process. In the process of the suction cup 106 releasing the film, the film in the gap between the suction cup 106 and the placement box 4 is in free fall motion. Since the film is relatively light, the film is prone to inaccurate attachment position during the free fall process, which is not conducive to subsequent heat sealing operations. The present invention, through the arrangement of the adsorbent 105 and the adsorbent 2 104, utilizes the vacuum degree and the elastic force of the spring 1054 to achieve the operation of completely pressing the film onto the placement box 4. There is no phenomenon of the film doing free fall motion in the gap between the suction cup 106 and the placement box 4, and in the flipping process, the film that has been attached to the placement box 4 will not be touched, which is not only conducive to subsequent heat sealing operations, but also more conducive to ensuring a good film application effect and excellent food quality.

[0047] The heat sealing assembly 6 includes a gantry 61 fixedly mounted on the side wall of the mounting frame 2, an electric telescopic column three 62 fixedly mounted on the top of the gantry 61, an output end of the electric telescopic column three 62 passes through the top of the gantry 61, an output end of the electric telescopic column three 62 is fixedly connected to a load-bearing box 63, a heating controller 64 is fixedly mounted inside the load-bearing box 63, a heating plate 65 is arranged below the load-bearing box 63, the heating plate 65 and the load-bearing box 63 are fixedly connected via a mounting column 66, and the heating plate 65 and the heating controller 64 are electrically connected via a wire 67.

[0048] After the film pasting is completed, when the conveyor belt 3 conveys the placement box 4 with the film to the bottom of the heating plate 65, the conveyor belt 3 stops rotating, and the heating controller 64 supplies power to the heating plate 65 through the wire 67 to heat up the heating plate 65, and then starts the electric telescopic column 3 62, and drives the heating plate 65 to move downward synchronously through the load-bearing box 63 and the mounting column 66, presses the high-temperature heating plate 65 on the film, heats the film, and makes the film stick to the placement box 4, thereby achieving heat sealing. After the heat sealing is completed, the various components of the heat sealing assembly 6 return to their original positions, and the conveyor belt 3 continues to rotate to convey the unheat-sealed film over and convey the heat-sealed film away.

[0049] The collecting assembly 20 includes an F-shaped bracket 201 fixedly mounted on the side wall of the mounting frame 2 and an electric telescopic column 202 fixedly mounted horizontally on the F-shaped bracket 201. The output end of the electric telescopic column 202 is fixedly connected to a collecting bucket 203. When damaged films or films with poor air tightness are collected, the electric telescopic column 202 is started to extend, driving the collecting bucket 203 to extend toward the middle of the conveyor belt 3 to collect the films dropped from the suction cup 106. After the collection is completed, the electric telescopic column 202 drives the collecting bucket 203 to reset for next use.
