Description

Technical Field

[0001] This invention relates to the field of food packaging, and more particularly to a bagged food packaging device that packages individually small food items into a large packaging bag in a certain quantity. Background Technology

[0002] In the food packaging industry, for the sake of convenience in storage, transportation, sales and cost considerations, more and more foods are packaged in bags. Especially with people’s increasing requirements for hygiene, each food item in the bag needs to be individually sealed first, which is more convenient and hygienic to consume. Therefore, it involves the repackaging operation of individually sealed small bags of food into relatively large packaging bags in a certain quantity.

[0003] When individual food items are irregular in shape and size, and have a certain degree of hardness and are relatively light, it is difficult to repackage them using traditional weighing methods. Therefore, they are often packaged according to quantity. For example, when packaging betel nuts, one, two, or four slices are often vacuum-sealed into small bags, and then two, three, or six vacuum-sealed bags of betel nuts are sealed into bags of the corresponding size. Because the shapes and sizes of the vacuum-sealed bags of betel nuts are not consistent, their weight is relatively light, and their surfaces are not smooth, it is difficult to use automated packaging machines for repackaging. Instead, manual repackaging is often used, followed by sealing the bag opening directly, or heat sealing the bag opening with tools. As a result, the repackaging efficiency is low, and the accuracy of repackaging cannot be effectively guaranteed. Furthermore, although some companies use existing packaging machines to automatically package similar food items like betel nuts, most of these existing packaging machines consist of a traditional rotary packaging machine body plus a feeding system. These machines often occupy a large area, are noisy, require multiple people to supervise, and are often costly, making them unsuitable for small food companies and individual users.

[0004] Therefore, there is an urgent need for a bagged food packaging device that is simple in structure, reasonable in layout, efficient and accurate to meet the needs of automated production. Summary of the Invention

[0005] The purpose of this invention is to provide a bagged food dispensing device that is simple in structure, reasonable in layout, efficient and accurate, so as to meet the needs of automated production.

[0006] To achieve the above objectives, this invention discloses a bagged food packaging device for packaging individually packaged small bags of food into a relatively large packaging bag in a certain quantity. The bagged food packaging device includes a machine base, a feeding mechanism, a bag supply mechanism, and a heat-sealing mechanism arranged sequentially on the machine base, and a bag filling mechanism arranged below the machine base. The bag supply mechanism's suction cups sequentially pick up packaging bags stacked in the feeding hopper from below and flip them to a position opposite to the bag filling mechanism. The two feed cylinders of the feeding mechanism alternately receive the quantity of small bags of food to be packaged in the packaging bag. The corresponding small bags of food are alternately transferred to the bagging mechanism for feeding. The bagging mechanism reciprocates linearly between the bag feeding mechanism, the feeding mechanism, and the heat sealing mechanism to obtain the packaging bags provided by the bag feeding mechanism. With the cooperation of the bag feeding mechanism, the bag opening is opened, allowing the small bags of food at the feeding mechanism to fall into the packaging bag. The filled packaging bag is then transferred to the heat sealing mechanism, which heat seals the opening of the filled packaging bag transferred by the bagging mechanism.

[0007] Preferably, the feeding mechanism further includes a support frame mounted on the machine base, a rotary driver mounted on the support frame, and an opening and closing assembly mounted at the bottom of the machine base and located at the first through hole of the machine base. The two material cylinders are symmetrically connected to the output end of the rotary driver and are both straight cylinders that run vertically through the machine base. The opening and closing assembly opens or closes the first through hole by performing an opening and closing action.

[0008] Preferably, the opening and closing assembly includes two opening and closing parts and two opening and closing cylinders connected to the two opening and closing parts in a one-to-one correspondence. The two opening and closing parts are symmetrically slidably disposed on the bottom of the machine base along the Y-axis with the center of the first through hole as the center. The upper ends of the two opening and closing parts are respectively slidably abutting against the machine base, and the two upper ends can be joined together to form a support platform. The lower ends of the two opening and closing parts are both arc-shaped, and the two lower ends are symmetrically arranged at the center position of the bottom edge of the opposite ends of the two upper ends.

[0009] Preferably, the feeding mechanism further includes a pushing component mounted on the support frame and located above the first through hole, the pushing component being used to blow air into the material cylinder that is rotated to the opposite side and / or to push the small bag of food in the material cylinder.

[0010] Preferably, the bagging mechanism includes a Y-axis linear module, two clamping components slidably mounted on the Y-axis linear module and both capable of linear movement along the Z-axis, and an adsorption component. The two clamping components are arranged symmetrically with respect to the adsorption component. The Y-axis linear module drives the two clamping components and the adsorption component to reciprocate linearly along the Y-axis between the bag feeding mechanism, the material dispensing mechanism, and the heat sealing mechanism. This allows the two clamping components to clamp the packaging bag from opposite left and right sides, and the adsorption component to adsorb and pull the opposite front sidewall of the clamped packaging bag from the opposite front side. Thus, with the adsorption force of the bag feeding mechanism on the rear sidewall of the packaging bag, the bag opening is opened.

[0011] Preferably, the clamping assembly includes a clamping frame, a fixed block, a clamping cylinder, a movable block, and an inclined connecting block. The fixed block and the clamping cylinder are respectively installed on the left and right opposite sides of the clamping frame. The first end of the movable block is pivotally connected to the output end of the clamping cylinder, and the tail end of the movable block is detachably abutted against the fixed block. The first end of the connecting block is pivotally connected to the clamping frame and located between the fixed block and the clamping cylinder, and the tail end of the connecting block is pivotally connected to the movable block and located near the first end of the movable block.

[0012] Preferably, the adsorption assembly includes an upper vacuum suction cup and a lower vacuum suction cup arranged at intervals along the Z-axis direction. The upper vacuum suction cup adsorbs the upper part of the packaging bag, and the lower vacuum suction cup adsorbs the lower middle part of the packaging bag.

[0013] Preferably, the bagging mechanism further includes a lifting cylinder connected to the output end of the Y-axis linear module, a mounting base connected to the output end of the lifting cylinder, a lifting cylinder and an adjusting cylinder installed on the front and rear opposite sides of the mounting base, and a pushing cylinder connected to the output end of the lifting cylinder. The adsorption component is connected to the output end of the pushing cylinder, and the two clamping components are symmetrically connected to the output end of the adjusting cylinder.

[0014] Preferably, the hopper is mounted above the second through hole of the machine base, and the stacked packaging bags are supported in the hopper. The bag feeding mechanism further includes a lifting cylinder mounted on the machine base, a rotary cylinder connected to the output end of the lifting cylinder and located at the bottom side of the machine base, and a suction cup positioning frame connected to the output end of the rotary cylinder and vertically inserted into the second through hole. The suction cup positioning frame is used to fix the bag-picking suction cup, and the rotary cylinder is used to drive the bag-picking suction cup to rotate 90°.

[0015] Preferably, the heat-sealing mechanism includes two sealing grippers symmetrically arranged along the X-axis, and two pressing plates and two hot pressing plates symmetrically arranged along the Y-axis, with the two pressing plates located on the opposite lower side of the corresponding hot pressing plates. The two sealing grippers cooperate to clamp or release the packaging bag from the left and right opposite sides, the two pressing plates cooperate to press the bag opening from the front and rear opposite sides of the packaging bag to shrink the bag opening, and the two hot pressing plates cooperate to heat-seal the bag opening from the front and rear opposite sides of the packaging bag.

[0016] Compared with the prior art, the feeding mechanism, bag supply mechanism, and heat sealing mechanism of the bagged food packaging device provided by this invention are arranged sequentially on the machine platform, while the bag filling mechanism is arranged below the machine platform. The bag supply mechanism, in conjunction with its suction cups, sequentially picks up and flips the stacked packaging bags from below into positions opposite the bag filling mechanism. This allows the bag filling mechanism to perform bag picking with only a small movement, effectively improving sealing efficiency. When the bag filling mechanism moves the packaging bags to the area below the feeding mechanism, the two feed cylinders of the feeding mechanism alternately transfer the received food to the bag filling mechanism. The upper part of the feeding mechanism facilitates the placement of small food bags into the lower packaging bag. Furthermore, the continuous feeding from the two feeding cylinders improves sealing efficiency. Additionally, since the number of small food bags received by each cylinder corresponds to the number of small food bags to be sealed in the packaging bag, the consistency of the number of small food bags in each packaging bag is easily and effectively ensured, significantly improving sealing accuracy. When the bagging mechanism moves the packaging bag containing the small food bags to the heat-sealing mechanism, the heat-sealing mechanism automatically heat-seals the bag opening, completing the entire sealing operation. The bagged food dispensing device of this invention has a simple overall structure, small size, and a reasonable and compact layout. It effectively shortens the travel distance between the bagging mechanism and the feeding mechanism, dispensing mechanism, and heat-sealing mechanism, resulting in high sealing efficiency and better adaptability to the needs of automated production.

[0029] To illustrate the technical content and structural features of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0030] See Figure 1 and Figure 8 This invention provides a bagged food packaging device 100 for packaging individually packaged small bags of food into a relatively large packaging bag 200 in a certain quantity. Each small bag can contain 1, 2, 3, or 4 pieces of food, the specific quantity depending on the shape, firmness, and size of the food. The small bags of food can be vacuum-packed, and each packaging bag 200 can contain at least two small bags of food. In this application, the food specifically includes, but is not limited to, areca nuts. Each vacuum-packed small bag contains 3, 4, or 6 areca nuts, and the small bags of areca nuts are packaged in groups of 6, 8, or 12 bags in packaging bags of corresponding sizes. Specifically, the bagged food packaging device 100 provided in a preferred embodiment of this invention includes a machine base 10, a feeding mechanism 20, a bag supply mechanism 30, and a heat sealing mechanism 50 arranged sequentially on the machine base 10, and a bagging mechanism 40 arranged below the machine base 10. It should be noted that, for ease of understanding, the X-axis, Y-axis and Z-axis directions involved in the bagged food dispensing device 100 provided by the present invention correspond to the longitudinal direction, transverse direction and vertical direction of the machine tool 10, respectively.

[0031] See Figures 1 to 12Overall, the bag-feeding mechanism 30's suction cup 31 sequentially picks up the packaging bags 200 stacked in the hopper 32 from below and flips them to a position opposite to the bagging mechanism 40, thus facilitating the bagging mechanism 40's acquisition of empty packaging bags 200. The two feed cylinders 21 of the dispensing mechanism 20 alternately receive small bags of food and alternately transfer them to the top of the bagging mechanism 40 for dispensing, thus facilitating the bagging mechanism 40's insertion of the small bags of food into the packaging bags 200 from below. The number of small bags of food received by each feed cylinder 21 corresponds to the number of small bags of food to be packaged in each packaging bag 200, thus simply and effectively ensuring the consistency of the number of small bags of food packaged in each packaging bag 200 and effectively improving the accuracy of packaging. The bagging mechanism 40 reciprocates linearly between the bag feeding mechanism 30, the material dispensing mechanism 20, and the heat sealing mechanism 50, moving back and forth between them. Specifically, it reciprocates linearly along the Y-axis to obtain the packaging bag 200 provided by the bag feeding mechanism 30. With the cooperation of the bag feeding mechanism 30, it opens the opening of the packaging bag 200, allowing the small bag of food from the material dispensing mechanism 20 to fall into the packaging bag 200. The packaged packaging bag 200 is then transferred to the heat sealing mechanism 50, where it heat seals the packaged packaging bag 200 conveyed by the bagging mechanism 40, thus completing the entire sealing operation.

[0032] See Figure 2 Specifically, the machine base 10 is provided with a first through hole 11, a second through hole 12 and a third through hole 13 in sequence. The first through hole 11, the second through hole 12 and the third through hole 13 are arranged in a one-to-one correspondence with the feeding mechanism 20, the bag feeding mechanism 30 and the heat sealing mechanism 50, so as to facilitate the feeding mechanism 20, the bag feeding mechanism 30 and the heat sealing mechanism 50 to perform feeding, bag feeding and heat sealing actions respectively.

[0033] The following combination Figures 1 to 4 The specific structure and working principle of the feeding mechanism 20 are explained below:

[0034] See Figure 1 and 3The feeding mechanism 20 also includes a support frame 22 mounted on the machine base 10 and a rotary driver 23 mounted on the support frame 22. The two material cylinders 21 are symmetrically connected to the output end of the rotary driver 23, so that they rotate synchronously under the drive of the rotary driver 23 to achieve alternating material receiving and discharging. Both material cylinders 21 are straight cylinders that run vertically through each other. The rotary driver 23 drives the two material cylinders 21 to rotate 180° each time, so that they can only discharge material when they are rotated to a position opposite to the first through hole 11. Specifically, in some embodiments, in order to achieve smoother material receiving and discharging, the feeding mechanism 20 also includes a carrier tray 24 arranged on the machine base 10. The carrier tray 24 has a through hole corresponding to the first through hole 11. The lower ends of the two material cylinders 21 slidably abut against the carrier tray 24, so that when rotating, the small bags of food they receive slide on the carrier tray 24 to a position opposite to the first through hole 11 and the through hole.

[0035] See Figure 3 and Figure 4 In some embodiments, the material cylinder 21 has a split structure, specifically including two interlocking annular portions 211, with at least one of the two annular portions 211 being adjustablely fitted into the other annular portion 211, so that the size of the carrying area enclosed by the two is adjustable, thereby adapting to the carrying of small bags of food of different sizes and quantities. Specifically, the feeding mechanism 20 also includes two adjusting cylinders 25 mounted on the support frame 22 and located below the rotary driver 23. The two adjusting cylinders 25 are connected to the two material cylinders 21 in a one-to-one correspondence, wherein each adjusting cylinder 25 is connected to the two annular portions 211 of the corresponding material cylinder 21, for driving the two annular portions 211 to move towards each other or away from each other, so as to adjust the fitting position of the two, thereby changing the size of the carrying area enclosed by the two.

[0036] See Figures 2 to 4 Furthermore, in some embodiments, to achieve better control over the dropping of the small bags of food, the feeding mechanism 20 further includes an opening and closing component 26 installed at the bottom of the machine base 10 and located at the first through hole 11 of the machine base 10. The opening and closing component 26 opens or closes the first through hole 11 by performing an opening and closing action relative to the first through hole 11, so that the small bags of food in the material cylinder 21 can pass through the first through hole 11 and drop into the packaging bag 200. Specifically, the opening and closing component 26 includes two opening and closing parts 261 and two opening and closing cylinders 262 connected to the two opening and closing parts 261 in a one-to-one correspondence. The two opening and closing parts 261 are symmetrically slidably arranged at the bottom of the machine base 10 along the Y-axis direction with the center of the first through hole 11 as the center, so that they move towards each other or away from each other under the drive of the opening and closing cylinders 262 to close or open the first through hole 11, thereby preventing or allowing feeding.

[0037] Specifically, the upper ends 2611 of the two opening / closing parts 261 are slidably abutted against the machine base 10, and the two can be joined to form a support platform to support or release the small bag of food in the material cylinder 21 at the first through hole 11 from the bottom. The lower ends 2612 of the two opening / closing parts 261 are both arc-shaped, and the two lower ends 2612 are symmetrically arranged at the center of the bottom edge of the opposite ends of the two upper ends 2611, so as to facilitate insertion into the bag opening of the packaging bag 200 to open the bag opening from the inside to the outside for fixation. The upper end of the lower end 2612 is relatively wide and the lower end is relatively narrow, which makes it easier to insert into the bag opening. In addition, the lower end 2612 can be extended downward and outward from the center of the bottom edge of the upper end 2611, which simplifies the structure and effectively reduces manufacturing costs. When the two opening and closing parts 261 move in opposite directions to release the material, the two lower ends 2612 that are far apart from each other open and fix the bag opening from the inside to the outside, and the two upper ends 2611 that are far apart from each other release the load on the small bag of food in the material cylinder 21 to release the material. The small bag of food can fall smoothly into the packaging bag 200, effectively improving the bagging efficiency.

[0038] like Figure 2 and Figure 4 As shown, in some embodiments, in order to improve the stability of the movement of the two opening and closing parts 261, the opening and closing assembly 26 further includes two arc-shaped positioning parts 263. The two positioning parts 263 are symmetrically arranged at the bottom of the machine base 10 along the X-axis direction at the edge of the first through hole 11. The two opening and closing parts 261 are symmetrically inserted between the two positioning parts 263 and the machine base 11 along the Y-axis direction. Thus, under the guidance and limiting effect of the two positioning parts 263, the movement is stable and accurately positioned, thereby improving the feeding accuracy and efficiency.

[0039] See Figure 3 and Figure 4Furthermore, in some embodiments, the dispensing mechanism 20 further includes a pushing component 27 mounted on the support frame 22 and located above the first through hole 11. The pushing component 27 is used to blow air into the material cylinder 21 that rotates to the opposite side and / or push the small bag of food in the material cylinder 21 to accelerate the falling speed of the small bag of food. Specifically, the dispensing mechanism 20 also includes a mounting frame 271 mounted on the support frame 22, a lifting motor 272 mounted on the mounting frame 271, a pushing tube 273 connected to the output end of the lifting motor 272, and a miniature air pump 274 housed in the pushing tube 273. The miniature air pump 274 is used to blow air into the material cylinder 21 to accelerate the dispensing of the small bag of food, improve the bagging efficiency, and can move linearly along the Z-axis direction under the drive of the lifting motor 272 to adjust the distance with the material cylinder 21 and obtain a better blowing effect. The push tube 273 can also be used to push the small bags of food in the material cylinder 21, which can also speed up the feeding process. Especially when occasional blockages occur, the push tube 273 can quickly clear the blockage and facilitate the feeding. As for the micro air pump 274, the existing micro air pump is known in the art in terms of its structure and control principle. As long as it can be housed in the push tube 273 to perform the blowing function, it will not be described in detail here.

[0040] In addition, in some embodiments, the center of the opposite ends of the upper parts 2611 of the two opening and closing parts 261 is recessed in the direction away from each other, thereby forming an air supply channel between the two opening and closing parts 261. When the bagging mechanism 40 moves the packaging bag 200 with the bag opening already partially opened to the area below the first through hole 11, the micro air pump 274 can first blow air into the bag opening to open the packaging bag 200 more fully. Then, the two opening and closing parts 261 move in opposite directions to support the bag opening and release the material, further improving the smoothness of the small bag of food falling, thereby further improving the bagging efficiency.

[0041] The following combination Figure 1 , Figure 2 , Figures 5 to 7 The specific structure and working principle of the bagging mechanism 40 are explained below:

[0042] See Figure 1 and Figure 5Specifically, the bagging mechanism 40 includes a Y-axis linear module 41, two clamping components 42 slidably mounted on the Y-axis linear module 41 and capable of linearly moving along the Z-axis, and an adsorption component 43. The two clamping components 42 are arranged symmetrically with the adsorption component 43 as the center. The Y-axis linear module 41 is specifically any one of synchronous belt type, ball screw type, and linear motor type, used to drive the two clamping components 42 and the adsorption component 43 to perform linear reciprocating motion along the Y-axis, thereby moving back and forth between the bag feeding mechanism 30, the material dispensing mechanism 20, and the heat sealing mechanism 40. This allows the two clamping components 42 to clamp the packaging bag 200 from the left and right opposite sides, and allows the adsorption component 43 to adsorb and pull the opposite front sidewall of the clamped packaging bag 200 from the opposite front side. Thus, with the cooperation of the adsorption force of the bag feeding mechanism 30 on the rear sidewall of the packaging bag 200, the bag opening of the packaging bag 200 is opened.

[0043] See Figure 5 Specifically, the clamping assembly 42 includes a clamping frame 421, a fixed block 422, a clamping cylinder 423, a movable block 424, and a connecting block 425 arranged at an inclination. The fixed block 422 and the clamping cylinder 423 are respectively installed on the left and right opposite sides of the clamping frame 421. The first end of the movable block 424 is pivotally connected to the output end of the clamping cylinder 423, and the tail end of the movable block 424 is detachably abutted against the fixed block 422. The first end of the connecting block 425 is pivotally connected to the clamping frame 421 and located between the fixed block 422 and the clamping cylinder 423. The tail end of the connecting block 425 is pivotally connected to the movable block 424 and located near the first end of the movable block 424. The connecting block 425 is pivotally connected to the clamping frame 421, the movable block 424 is pivotally connected to the clamping cylinder 423, and the connecting block 425 is pivotally connected to the movable block 424 via pivot shafts 426, 427, and 428, respectively.

[0044] When the movable block 424 rotates around the pivot shaft 427 under the drive of the clamping cylinder 423 to abut or separate from the fixed block 422, the three pivot shafts 426, 427 and 428 are always at the three vertices of the triangle, thus forming a stable structure. The connecting block 425 can play a good guiding support and limiting role, so that the movable block 424 can rotate flexibly and accurately to abut against the fixed block 422, so that the two clamp or release the packaging bag 200 from the front and rear sides of the packaging bag 200 located between them. The two clamping components 42 clamp and fix the packaging bag 200 from the left and right ends of the packaging bag 200 respectively.

[0045] Specifically, in some embodiments, the fixed block 422 is in the shape of an "I" and the movable block 424 is in the shape of an "L". The movable block 424 can achieve contact and separation with the fixed block 422 by rotating slightly, resulting in a more compact structure. Furthermore, the contact surfaces of the fixed block 422 and the movable block 424 are provided with corresponding toothed structures to increase friction and make the clamping more secure.

[0046] See Figures 5 to 7 Specifically, in some embodiments, the distance between the two clamping components 42 is adjustable to accommodate clamping different packaging bags 200. More specifically, the bagging mechanism 40 also includes a lifting cylinder 44 connected to the output end of the Y-axis linear module 41, a mounting base 45 connected to the output end of the lifting cylinder 44, lifting cylinders 46 and adjusting cylinders 47 mounted on opposite sides of the mounting base 45, and a pushing cylinder 48 connected to the output end of the lifting cylinder 46. The adsorption component 43 is connected to the output end of the pushing cylinder 48, and the two clamping components 42 are symmetrically connected to the output end of the adjusting cylinder 47. The lifting cylinder 44 drives the two clamping components 42 and the adsorption component 43 to move synchronously along the Z-axis for lifting and lowering, while the adjusting cylinder 47 drives the two clamping components 42 to move towards each other or away from each other along the X-axis to adjust the distance between them, thereby matching the width of the packaging bag 200 to be clamped. The adsorption component 43 can also move linearly along the Z-axis and Y-axis directions under the drive of the lifting cylinder 46 and the pushing cylinder 48, so as to open the bag opening of the packaging bag 200 held by the two clamping components 42.

[0047] Specifically, the adsorption assembly 43 includes an upper vacuum suction cup 431 and a lower vacuum suction cup 432 arranged at intervals along the Z-axis. The upper vacuum suction cup 431 adsorbs and fixes the upper end of the packaging bag 200 of a certain length, thereby cooperating with the bag supply mechanism 30 to initially open the opening of the packaging bag 200. The lower vacuum suction cup 432 adsorbs and fixes the lower middle end of the packaging bag 200 of a certain length. The diameter of the upper vacuum suction cup 431 is smaller than the diameter of the lower vacuum suction cup 432. There are two upper vacuum suction cups 431 and one lower vacuum suction cup 432.

[0048] The following combination Figure 1 , Figure 2 , Figure 8 and Figure 9 The specific structure and working principle of the bag supply mechanism 30 are explained below:

[0049] Specifically, the hopper 32 is mounted above the second through hole 12 of the machine base 10 via two support plates 321, and multiple stacked packaging bags 200 are supported in the hopper 32. The bag feeding mechanism 30 also includes a lifting cylinder 33 mounted on the machine base 10, a rotary cylinder 34 connected to the output end of the lifting cylinder 33 and located at the bottom end of the machine base 10, and a suction cup positioning frame 35 connected to the output end of the rotary cylinder 34 and vertically inserted into the second through hole 12. The suction cup positioning frame 35 is used to fix the bag-picking suction cup 31. Among them, the bag-picking suction cup 31 is a vacuum suction cup, and there are multiple of them, including but not limited to bag-picking suction cups 31 arranged corresponding to the upper vacuum suction cup 431 and the lower vacuum suction cup 432 of the adsorption assembly, so as to achieve firm and stable adsorption and transfer. During feeding, the bag-picking suction cup 31 adsorbs the packaging bag 200 located at the bottom of the hopper 32 each time. The lifting cylinder 33 then drives the bag-picking suction cup 31 to move downward with the adsorbed packaging bag 200. Then, the rotating cylinder 34 drives the bag-picking suction cup 31 to rotate 90° relative to the hopper 32, thereby cooperating with the bagging mechanism 40 to pick up and open the bag.

[0050] The following combination Figure 1 , Figure 2 , Figures 10 to 12 The specific structure and working principle of the heat sealing mechanism 50 are explained below:

[0051] Specifically, the heat sealing mechanism 50 includes two sealing grippers 51 arranged symmetrically along the X-axis, two pressing plates 52 arranged symmetrically along the Y-axis, and two hot pressing plates 53 arranged symmetrically along the Y-axis. The sealing grippers 51, hot pressing plates 53, and pressing plates 52 are arranged sequentially from top to bottom along the Z-axis. The two sealing grippers 51 cooperate to clamp or release the packaging bag 200 from the left and right opposite sides of the opposite upper end. The two pressing plates 52 cooperate to press the opening of the packaging bag 200 from the front and rear opposite sides of the opposite upper end to close the opening. The two hot pressing plates 53 cooperate to heat-press the opening of the packaging bag 200 from the front and rear opposite sides of the closed upper end to achieve the closure of the bag opening. The sealing gripper 51 includes two symmetrically arranged grippers 511 and clamping cylinders 512 connected to the two grippers 511 respectively. The clamping cylinders 512 are used to drive the two grippers 511 to move towards each other or away from each other to clamp or release the packaging bag 200 located between them. The clamping surfaces of the two grippers 511 that cooperate have toothed structures, thereby achieving a firm clamping. It should be noted that the hot press plate 53 is also connected to the heating rod 531, and the heating rod 531 is also connected to an external heater. When the heating rod 531 heats up under the drive of the heater, the hot press plate 53 achieves heat sealing of the bag opening through heat conduction.

[0052] More specifically, the heat sealing mechanism 50 also includes a protective cover 54 covering the third through hole 13 of the machine base 10, a first U-shaped frame 55 mounted on the top inner wall of the protective cover 54, a gripper cylinder 56 mounted on the first U-shaped frame 55, two L-shaped frames 561 symmetrically connected to the output end of the gripper cylinder 56 along the X-axis, a second U-shaped frame 57 mounted on the bottom side end of the gripper cylinder 56, two pressing cylinders 58 symmetrically connected to the two vertical plates 571 of the second U-shaped frame 57 along the Y-axis, and a hot pressing cylinder 59 mounted on the horizontal plate 572 of the second U-shaped frame 57. Two clamping cylinders 512 are symmetrically mounted on two L-shaped frames 561. Two sealing claws 51 are connected one-to-one to the output ends of the two clamping cylinders 512. Driven by the claw cylinders 56, they move towards each other or away from each other to adjust the distance between them, so as to accurately clamp the packaging bag 200 located between them. This method is suitable for clamping packaging bags 200 of different widths. Two pressing plates 52 are connected one-to-one to the output ends of two pressing cylinders 58. Driven by the two pressing cylinders 58, they move towards each other or away from each other to press against the front and rear sidewalls of the packaging bag 200 at their respective upper ends, so that the front and rear sidewalls of the packaging bag 200 come closer together to shrink the bag opening. Two hot press plates 53 are symmetrically connected to the output end of the hot press cylinder 59 along the Y-axis, so that they move towards each other or away from each other under the drive of the hot press cylinder 59 to heat seal the opening of the packaging bag 200.

[0053] Please see Figures 1 to 12 The working principle of the bagged food dispensing device 100 of the present invention will be explained as follows:

[0054] First, at the initial work station, the bagging mechanism 40 is located below the first through hole 11 of the feeding mechanism 20. When the material cylinder 21 in the feeding mechanism 20, which is relatively far away from the first through hole 11, begins to receive small bags of food, the bag-feeding mechanism 30's bag-taking suction cup 31 picks up the packaging bag 200 at the bottom of the material bin 32 and flips it downward and forward to the position opposite to the bagging mechanism 40.

[0055] Next, the bagging device 40 moves slightly toward the bag supply mechanism 30, that is, moves backward. First, the bag-taking claw 41 clamps the packaging bag 200 from the left and right opposite sides. Then, the adsorption component 42 adsorbs the front side wall of the clamped packaging bag 200 from the front. Combined with the adsorption of the rear side wall of the packaging bag 200 by the bag-taking suction cup 31 of the bag supply mechanism 30, the bag opening of the packaging bag 200 is initially opened. The bagging device 40 then brings the packaging bag 200 with the opening back to the initial position and moves it up to the lower end 2612 of the two opening and closing parts 261 placed at the first through hole 11. At the same time, the material cylinder 21, which is full of the small bag of food to be packaged, also rotates to the first through hole 11.

[0056] Then, the feeding component 27 blows air into the packaging bag 200 to open the packaging bag 200 relatively large. Then, the opening and closing component 26 moves to support and fix the bag opening of the packaging bag 200 from the inside to the outside, so that the small bag of food in the material cylinder 21 falls smoothly into the packaging bag 200 whose bag opening has been supported and fixed, thereby completing the bagging operation. After the bagging is completed, the bagging device 40 continues to move the packaging bag 200 containing the small bag of food toward the heat sealing mechanism 50 at the rear.

[0057] Finally, the two sealing jaws 51 of the heat sealing mechanism 50 are activated to clamp the packaging bag 200 conveyed by the bagging device 40. The bagging device 40 then moves in the opposite direction and returns to its initial position. Next, the two pressing plates 52 of the heat sealing mechanism 50 are activated to press the packaging bag 200 held by the two sealing jaws 51 from the front and rear sides, so that the opening of the packaging bag 200 is relatively reduced and closed. Then, the two hot pressing plates 53 of the heat sealing mechanism 50 are activated to heat press the closed packaging bag 200 from the front and rear sides to heat seal the bag opening. After the heat sealing is completed, the two sealing jaws 51 move away from each other and release the packaging bag 200, allowing it to fall into the receiving box below.

[0058] By repeatedly performing the above actions, the process of packaging small bags of food into a certain quantity in a large packaging bag 200 can be automated, thus meeting the needs of automated production lines.

[0059] It should be noted that when the feeding cylinder 21 receives small bags of food, the corresponding number of small bags of food can be manually checked before being placed into the feeding cylinder 21 in sequence. Alternatively, the feeding action can be completed by a robotic arm. Of course, the corresponding number of small bags of food can also be conveyed into the feeding cylinder 21 by a conveyor line or hopper, making it more flexible to use.

[0060] Compared with the prior art, the bagged food packaging device 100 provided by the present invention has a feeding mechanism 20, a bag supply mechanism 30, and a heat sealing mechanism 50 arranged sequentially on the machine base 10, while the bag filling mechanism 40 is arranged below the machine base 10. Combined with the bag-picking suction cup 31 of the bag supply mechanism 30, the packaging bags 200 stacked in its hopper 32 are sequentially picked up from below and flipped to a position opposite to the bag filling mechanism 40. This allows the bag filling mechanism 40 to perform the bag picking operation with only a small movement, effectively improving the sealing efficiency. Furthermore, when the bag filling mechanism 40 moves the packaging bag 200 below the feeding mechanism 20, the two material cylinders 21 of the feeding mechanism 20 alternately transfer the received small bags of food to a position above the bag filling mechanism 40, thus facilitating not only the dropping of the small bags of food into the packaging bags 200 below, but also, through the non-... Intermittent feeding further improves packaging efficiency. In addition, since the number of small bags of food received by the material cylinder 21 each time corresponds to the number of small bags of food to be packaged in the packaging bag 200, the consistency of the number of small bags of food packaged in each packaging bag 200 is simply and effectively guaranteed, effectively improving the packaging accuracy. When the bagging mechanism 40 moves the packaging bag containing the small bags of food to the heat sealing mechanism 50, the heat sealing mechanism 50 heat seals the opening of the packaging bag 200 to seal it, thereby completing the entire packaging operation. The bagged food dispensing device 100 of the present invention has a simple overall structure, small size, reasonable and compact layout, effectively shortens the travel distance of the bagging mechanism 40 between the bag feeding mechanism 30, the material dispensing mechanism 20 and the heat sealing mechanism 50, and has high packaging efficiency and high packaging accuracy, making it more suitable for the needs of automated production.

[0061] The above-disclosed examples are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are within the scope of the present invention.
