Description

Technical Field

[0001] This utility model relates to a sealing machine for the production and processing of bagged food, belonging to the field of bagged food sealing equipment. Background Technology

[0002] Bagged food refers to food packaged in plastic bags. Due to the sealed packaging, it effectively prevents food from getting damp and moldy, and also effectively prevents the intrusion of contaminants such as dust and insect eggs, ensuring food hygiene and safety. In the production and processing of bagged food, the food is weighed and then packed into plastic bags, which are then sealed using a sealing device. Currently, bagged food is mostly sealed using heat sealing machines. However, existing heat sealing machines only have sealing functions and do not have packaging functions. For example, CN214824616U discloses a heat sealing device for a food packaging bag production line, and CN211309154U discloses a heat sealing machine for sealing plastic bags. When using these existing technologies, the food needs to be packed first using a food packaging device, then the packaged plastic bag needs to be transferred to the heat sealing machine, and then the plastic bag needs to be manually placed on the heat sealing part of the machine for sealing. This involves many steps, thus reducing work efficiency. Utility Model Content

A first linear guide assembly is installed on the left frame along the left-right direction. A movable plate is fixedly connected to the movable part of the first linear guide assembly. A displacement drive assembly is connected to the movable plate. Two clamping cylinders and two heat-sealing cylinders, symmetrically arranged front-to-back, are fixedly connected to the movable plate. Clamping plates are fixedly connected to the fixed plates of the two clamping cylinders, and mounting plates are fixedly connected to the fixed plates of the two heat-sealing cylinders. Heat-sealing plates are mounted on the two mounting plates. A mounting frame is provided at the upper end of the right frame. A second linear guide assembly and a... The third linear guide assembly, the second linear guide assembly, and the third linear guide assembly have front and rear guide troughs fixedly connected to their moving parts, respectively. Bag-supporting cylinders are installed on both the front and rear sides of the mounting frame. The fixing plates of the two bag-supporting cylinders are fixedly connected to the front and rear guide troughs, respectively. A lifting plate is slidably connected to the rear side of the right frame in the vertical direction. A swing rod is rotatably connected to both sides of the lifting plate. A bag-pulling cylinder is hinged between the two swing rods and the lifting plate. A pull rod is fixedly connected to the two swing rods. A lifting cylinder is installed on the mounting frame. The fixing plate of the lifting cylinder is fixedly connected to the lifting plate. A support base is fixedly connected to the middle of the right frame. A support plate is connected to the support base.

[0005] Furthermore, the first linear guide assembly includes two linear guide rails that are fixedly connected to the front and rear sides of the left frame, respectively. Each linear guide rail is slidably connected to a slider, and each slider is fixedly connected to the movable plate.

[0006] Furthermore, the displacement drive assembly includes a cylinder seat fixedly connected to the left frame and a drive plate fixedly connected to the moving plate. A displacement cylinder is mounted on the cylinder seat, and the piston rod of the displacement cylinder is fixedly connected to the drive plate.

[0007] Furthermore, rubber strips are installed on both clamping plates.

[0008] Furthermore, two guide rods are fixedly connected to the rear side of the right frame in the vertical direction, and guide holes corresponding to the two guide rods are passed through the lifting plate.

[0009] Furthermore, the top of the support base is provided with a stud, and the bottom of the support plate is provided with a threaded sleeve that is adapted to the thread of the stud.

[0010] Furthermore, the second linear guide assembly includes two front guide shafts fixedly connected to the front guide trough, and the mounting frame has front guide holes that correspond one-to-one with the two front guide shafts.

[0011] Furthermore, the third linear guide assembly includes two rear guide shafts fixedly connected to the rear guide groove, and the mounting frame has rear guide holes that correspond one-to-one with the two rear guide shafts.

[0012] Working principle and process:

[0013] In operation, a collection box is placed on the left frame. First, a plastic bag is placed over the lower end of the pull rod, the front guide chute, and the rear guide chute. Then, the two bag-supporting cylinders retract, causing the front and rear guide chutes to move in opposite directions to support the plastic bag. The weighed food then enters the plastic bag through the drop space formed by the front and rear guide chute. Next, the two bag-supporting cylinders extend, causing the front and rear guide chutes to move relative to each other, thus releasing the support on the plastic bag. The plastic bag containing the food falls downwards onto the pallet under its own weight. Simultaneously, the lifting cylinder and the two bag-pulling cylinders activate. The lifting cylinder drives the lifting plate downwards, causing the two swing rods and the two pull rods to move downwards with the plastic bag, ensuring the bag-pulling rod remains inside the bag. The bag-pulling cylinders, by extending, cause the two swing rods to swing to the sides, causing the two pull rods to move in opposite directions, pulling the upper end of the plastic bag into a straight line. The extension cylinder moves the moving plate to the right, causing the clamping plate and mounting plate to move to the end of the plastic bag. Then, the two clamping cylinders extend, causing the two clamping plates to move relative to each other and clamp the plastic bag, making the top of the plastic bag flat. Then, the lifting cylinder and the bag-pulling cylinder reset, causing the pull rod to return to its original position and disengage from the plastic bag. Then, the two heat-sealing cylinders extend, causing the two mounting plates to move relative to each other, causing the two heat-sealing plates to press the end of the plastic bag, thus achieving a heat seal. Then, the two heat-sealing cylinders reset, causing the two heat-sealing plates to return to their original position and disengage from the plastic bag. At the same time, the displacement cylinder resets, causing the moving plate to reset, and the plastic bag is brought to the top of the collection box through the clamping plate. Then, the two clamping cylinders reset, causing the two clamping plates to move in the opposite direction, thus releasing the clamping of the plastic bag and allowing the sealed plastic bag to fall into the collection box, thus completing the bagging process of one bag of food.

[0014] The advantages of this utility model compared with the prior art are:

[0015] The sealing machine for bagged food production and processing described in this utility model integrates packaging and sealing functions. It can not only seal plastic bags, but also bag food before sealing, thereby reducing the number of video transfers and effectively improving work efficiency. Attached Figure Description

[0023] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0024] Example 1:

[0025] like Figures 1 to 5 As shown, the sealing machine for bagged food production and processing of this utility model includes a left frame 6 and a right frame 1. A first linear guide assembly is installed on the left frame 6 along the left-right direction. A movable plate 11 is fixedly connected to the movable part of the first linear guide assembly. A displacement drive assembly is connected to the movable plate 11. Two clamping cylinders 14 and two heat-sealing cylinders 15 with front-to-back symmetry are fixedly connected to the movable plate 11. A clamping plate 12 is fixedly connected to the fixed plate of each of the two clamping cylinders 14. An mounting plate 13 is fixedly connected to the fixed plate of each of the two heat-sealing cylinders 15. A heat-sealing plate 26 is installed on each of the two mounting plates 13. The upper end of the right frame 1 is provided with a mounting frame 23. A second linear guide assembly and a third linear guide assembly are installed on the mounting frame 23 along the front-to-back direction. A front guide trough 17 and a rear guide trough 24 are fixedly connected to the moving parts of the first, second, and third linear guide components, respectively. Bag-supporting cylinders 20 are installed on both the front and rear sides of the mounting frame 23. The fixing plates of the two bag-supporting cylinders 20 are fixedly connected to the front guide trough 17 and the rear guide trough 24, respectively. A lifting plate 21 is slidably connected to the rear side of the right frame 1 in the vertical direction. A swing rod 18 is rotatably connected to both sides of the lifting plate 21. A bag-pulling cylinder 29 is hinged between the two swing rods 18 and the lifting plate 21. A pull rod 16 is fixedly connected to the two swing rods 18. A lifting cylinder 28 is installed on the mounting frame 23. The fixing plate of the lifting cylinder 28 is fixedly connected to the lifting plate 21. A support seat 2 is fixedly connected to the middle of the right frame 1. A support plate 5 is connected to the support seat 2.

[0026] When using, such as Figure 6As shown, a collection box 30 is placed on the left frame 6. First, a plastic bag 31 is placed over the lower end of the pull rod 16, the front guide chute 17, and the rear guide chute 24. Then, the two bag-supporting cylinders 20 retract, thereby causing the front guide chute 17 and the rear guide chute 24 to move in opposite directions to support the plastic bag 31. Then, the weighed food can enter the plastic bag 31 through the dropping space formed by the front guide chute 17 and the rear guide chute 24. Then, the two bag-supporting cylinders 20 extend, causing the front guide chute 17 and the rear guide chute 24 to move relative to each other, thereby canceling the movement of the plastic bag 31. As the plastic bag 31 tightens, the plastic bag 31 containing food moves downwards under its own weight and falls onto the tray 5. Simultaneously, the lifting cylinder 28 and the two bag-pulling cylinders 29 activate. The lifting cylinder 28 drives the lifting plate 21 downwards, thereby causing the two swing arms 18 and the two pull rods 16 to move downwards with the plastic bag 31, ensuring the pull rods remain inside the plastic bag 31. The bag-pulling cylinders 29, through their extension, cause the two swing arms 18 to swing to both sides, thereby causing the two pull rods 16 to move in the opposite direction, pulling the upper end of the plastic bag 31 into a straight line. The displacement drive assembly activates, driving the moving plate 11 to move to the right, thereby moving the clamping plate 12 and the mounting plate 13 to the end of the plastic bag 31. Then, the two clamping cylinders 14 extend, causing the two clamping plates 12 to move relative to each other and clamp the plastic bag 31, making the upper end of the plastic bag 31 flat. Then, the lifting cylinder 28 and the bag-pulling cylinder 29 reset, causing the pull rod 16 to reset and disengage from the plastic bag 31. Then, the two heat-sealing cylinders 15 extend, causing the two mounting plates 13 to move relative to each other, thereby causing the two heat-sealing plates 26 to press the plastic bag 31. The plastic bag 31 is heat-sealed, and then the two heat-sealing cylinders 15 are reset, which drives the two heat-sealing plates 26 to reset and detach from the plastic bag 31. At the same time, the displacement drive assembly is reset, which drives the moving plate 11 to reset. The plastic bag 31 is brought to the top of the collection box 30 through the clamping plate 12. Then the two clamping cylinders 14 are reset, which drives the two clamping plates 12 to move in the opposite direction, thereby releasing the clamping of the plastic bag 31 and allowing the sealed plastic bag 31 to fall into the collection box 30, thus completing the bagging process of a bag of food.

[0027] Example 2:

[0028] like Figures 1 to 6 As shown, based on Example 1,

[0029] Furthermore, the first linear guide assembly includes two linear guide rails 7 respectively fixedly connected to the front and rear sides of the left frame 6. Slider 8 is slidably connected to each of the two linear guide rails 7, and each slider 8 is fixedly connected to the moving plate 11. Through the cooperation of the linear guide rails 7 and the slider 8, the moving plate 11 can move directionally relative to the left frame 6, effectively ensuring the operational stability of the moving plate 11.

[0030] Furthermore, the displacement drive assembly includes a cylinder seat 9 fixedly connected to the left frame 6 and a drive plate 32 fixedly connected to the moving plate 11. A displacement cylinder 10 is mounted on the cylinder seat 9, and the piston rod of the displacement cylinder 10 is fixedly connected to the drive plate 32. The moving plate 11 can be driven to reciprocate by the extension and retraction of the displacement cylinder 10. The structure is simple and easy to control.

[0031] Furthermore, rubber strips 25 are installed on both clamping plates 12. The plastic bag 31 is pressed by the rubber strips 25, and the deformation ability of the rubber strips 25 ensures the clamping effect on the plastic bag 31.

[0032] Furthermore, two guide rods 22 are fixedly connected to the rear side of the right frame 1 in the vertical direction, and guide holes corresponding to the two guide rods 22 are passed through the lifting plate 21. Through the cooperation of the guide rods 22 and the guide holes, the directional sliding of the lifting plate 21 is realized, effectively ensuring the operational stability of the lifting plate 21.

[0033] Furthermore, the top of the support base 2 is provided with a stud 3, and the bottom of the tray 5 is provided with a threaded sleeve 4 that is adapted to the thread of the stud 3. By rotating the tray 5, the height of the tray 5 can be adjusted under the threaded engagement of the stud 3 and the threaded sleeve 4, thereby adapting to the sealing operation of plastic bags 31 of different heights.

[0034] Furthermore, the second linear guide assembly includes two front guide shafts 19 fixedly connected to the front guide trough 17, and the mounting frame 23 has front guide holes that correspond one-to-one with the two front guide shafts 19. The directional movement of the front guide trough 17 is achieved through the cooperation between the front guide shafts 19 and the front guide holes, resulting in a simple structure and stable operation.

[0035] Furthermore, the third linear guide assembly includes two rear guide shafts 27 fixedly connected to the rear guide trough 24, and the mounting frame 23 has rear guide holes that correspond one-to-one with the two rear guide shafts 27. The directional movement of the rear guide trough 24 is achieved through the cooperation between the rear guide shafts 27 and the rear guide holes, resulting in a simple structure and stable operation.
