Description

Technical Field

[0001] The utility model belongs to the technical field of sealing devices, and in particular relates to a sealing device for a sauce packaging machine. Background Art

[0002] In the production process of sauce bags, the bag film is filled with sauce, and the bag is sealed in sections from bottom to top at a certain distance. Finally, the sealed sauce bags are connected together evenly in sequence. However, since the sauce itself is a mixture of oils and materials, its contact with the bag film will cause the bag film to also be attached with a lot of grease. When the sealing machine is sealing, if the sealing pressure is insufficient or the sealing temperature is insufficient, the sealing cannot be completed. In order to achieve sufficient pressure in the production of the workshop nowadays, two sets of cylinders are often used to press the pressure heads against each other to achieve sealing. However, the use of two sets of cylinders itself will cause a large waste of energy, especially for the production process of sealing the sauce bag alone. Reducing costs can save a lot of production costs for the company. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a sealing device for a sauce bag machine, through the pullback of the first cylinder, the zigzag connecting rod seat of the connecting rod assembly that is rotatably connected to the bridge plate rotates, thereby pushing the first pressure head forward, and the pullback of the push plate will also pull the second pressure head back at the same time, the first pressure head and the second pressure head abut against each other to press the film together, and then the heating of the heating wire is used to complete the sealing. Only one set of cylinders is needed to complete the sealing, thereby reducing production costs.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A sealing device for a sauce packet machine comprises two sets of wall plates, a fixing assembly, a first cylinder, a connecting rod assembly, a first pressing head, a pressing rod assembly, a second pressing head and a heating assembly;

[0006] The fixing assembly comprises a fixing plate and a pushing plate, the left and right ends of the fixing plate are respectively connected to the two sets of wall plates, and the output end of the first cylinder passes through the fixing hole on the fixing plate and is connected to the pushing plate;

[0007] The connecting rod assembly includes a first push rod, a connecting rod seat, a second push rod, a push head and a bridge plate, the left and right ends of the bridge plate are respectively connected to the two sets of wall plates, the connecting rod seat is rotatably connected to the bridge plate, one end of the connecting rod seat is rotatably connected to the push plate through the first push rod, and the other end of the connecting rod seat is rotatably connected to the push head through the second push rod, the first pressure head is connected to the push head, the left and right ends of the push head are respectively sleeved on the movable column, and the first push rod, the connecting rod seat and the second push rod are in a zigzag structure;

[0008] The pressure rod assembly includes a movable plate, a movable column and a sleeve, the movable plate includes a front plate and a rear plate, the front plate and the rear plate are connected by an adjustment column, the movable column is connected to the push plate, the movable column passes through the front plate and is connected to the rear plate, the sleeve is sleeved on the movable column, the outer side wall of the sleeve is connected to the wall plate, the second pressure head is connected to the front plate, the first pressure head and the second pressure head correspond to each other and abut against each other under the drive of the first cylinder.

[0009] The heating assembly includes a second cylinder, a pressure plate, a pressure column and a heating wire. The second cylinder is connected to the rear plate, and the output end of the second cylinder passes through the rear plate to be connected to the pressure plate. The pressure column connected to the pressure plate passes through the front plate to be connected to the heating wire. The heating wire can be abutted and connected to the second pressure head under the drive of the second cylinder, and the pressure pad provided on the first pressure head corresponds to the heating wire.

[0010] The sealing device of the sauce bag machine adopts this structure, in order to realize that a single set of cylinders can press the first pressure head and the second pressure head together, it is necessary to make the first pressure head and the second pressure head move in opposite directions under the same action. The first cylinder is fixed on the fixed plate, and its output end is connected to the push plate through the fixed hole. The movable column connected to the push plate passes through the front plate of the movable plate and is connected to the rear plate. The front plate and the rear plate are connected by an adjusting column, and the spacing between the front plate and the rear plate can be adjusted. The connecting rod assembly connected to the first pressure head can be fixed only on the wall plate. Therefore, when the first cylinder is started and pulled back, the pushing plate will drive the second pressure head on the movable column to move in the direction of the first pressure head. When the first pressure head and the second pressure head are abutted, the sealing of the film can be achieved. In order to avoid positional displacement and rotation during the movement of the second pressure head, a sleeve is sleeved on the movable column, and the sleeve is connected to the wall plate, forcing the movable column to only be displaced in the front and rear positions of the sleeve.

[0011] However, the motionless first pressure head will cause insufficient pressure during the contact with the second pressure head, and during the sealing process, the film package is likely to be pressed on the first pressure head because the first pressure head is motionless, and cannot be separated, causing the film package to continue to move downward and continue to seal. The sealed sauce package and the unsealed film package are stacked together, and sealing again will cause the sauce package to burst, affecting the production progress and requiring complete cleaning before continuing the operation. If the first pressure head only extends forward when sealing and retracts after sealing, there will be a retracted space for the film package to separate from the area where the first pressure head is located under the action of gravity. Therefore, the connecting rod assembly is configured to be composed of the first push rod The connecting rod seat and the second push rod are arranged in a zigzag shape. The connecting rod seat can be rotatably connected to the bridge plate. The left and right ends of the bridge plate are fixed on the two sets of wall panels to play a role of stable fixation. The other end of the first push rod is connected to the push plate, and the other end of the second push rod is connected to the push head. Therefore, when the first cylinder pulls back, the push plate pulls back the first push rod, forcing the connecting rod seat to rotate, and the end of the connecting rod seat connected to the second push rod pushes forward, so that the push head pushes the first pressure head to move in the direction of the second pressure head, and the second pressure head will be pulled back at the same time as the first cylinder is pulled back, so that the first pressure head and the second pressure head move towards each other and abut against each other, which can provide greater sealing force.

[0012] The sealing requires heating of the sealing area to force the plastic to melt and stick together. Therefore, a second cylinder is set on the back plate. The second cylinder drives the pressure plate, and the pressure column on the pressure plate pushes the heating wire to move in the direction of the first pressure head until the heating wire pushes the film to abut against the pressure pad on the first pressure head to complete the heating and melting of the seal. After the melting and bonding is completed, the second cylinder is started to return the heating wire to the second pressure head. Since the sealing melting does not require too much pressing force, only the heating wire and the pressure pad need to abut against each other. Therefore, the second cylinder is a group of small cylinders and will not have much impact on energy consumption.

[0013] Furthermore, a limiting long hole is provided on the wall panel, and the extension parts at the left and right ends of the fixing plate are matched in the limiting long hole. A first adjustment hole is provided on the extension part, and an adjustment seat is provided on the wall panel. The second adjustment hole on the adjustment seat is connected to the first adjustment hole through a stud.

[0014] Compared with the prior art, the utility model has the following advantages: by starting the first cylinder, the second pressure head is moved toward the first pressure head during the pullback process, and the first pressure head is pushed out under the action of the connecting rod of the connecting rod assembly, so that the first pressure head and the second pressure head move toward each other and abut against each other, forming a greater sealing force, and the strokes of the two are close. After the film is sealed, the first pressure head and the second pressure head will both move away from the film, so that the film is separated from the area where the first pressure head and the second pressure head are located under the action of gravity, avoiding the film from sticking to the original place after the sealing is completed, causing the subsequent sealed sauce bag to burst, and the melting of the seal is achieved by the second cylinder pushing the heating wire to abut against the pressure pad. The device can save the use of a group of large cylinders and save energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Description of the working method of this utility model:

[0029] In order to realize that a single set of cylinders can press the first pressing head 5 and the second pressing head 7 together, the sealing device of the sauce packet machine adopts this structure. It is necessary to make the first pressing head 5 and the second pressing head 7 move in opposite directions under the same action. The first cylinder 3 is fixed on the fixed plate 21, and its output end passes through the fixed hole 22 and is connected to the push plate 23. The movable column 64 connected to the push plate 23 passes through the front plate 62 of the movable plate 61 and is connected to the rear plate 63. The front plate 62 and the rear plate 63 are connected by an adjustment column 66, and the distance between the front plate 62 and the rear plate 63 can be adjusted. The movable column 64 can be adjusted, and the connecting rod assembly 4 connected to the first pressing head 5 can be fixed only on the wall panel 1. Therefore, when the first cylinder 3 is started and pulled back, the pushing plate 23 will drive the second pressing head 7 on the movable column 64 to move in the direction of the first pressing head 5. When the first pressing head 5 and the second pressing head 7 are in contact, the sealing of the membrane can be achieved. In order to avoid positional displacement and rotation during the movement of the second pressing head 7, a sleeve 65 is sleeved on the movable column 64, and the sleeve 65 is connected to the wall panel 1, forcing the movable column 64 to be displaced only in the front and rear positions of the sleeve 65.

[0030] However, the motionless first pressing head 5 will cause insufficient pressure during the process of contacting with the second pressing head 7, and during the sealing process, the film package is likely to be pressed on the first pressing head 5 because the first pressing head 5 is motionless, and cannot be separated, causing the film package to continue to move downward and continue to seal. The sealed sauce bag and the unsealed film package are stacked together, and sealing again will cause the sauce bag to burst, affecting the production progress and requiring complete cleaning before continuing the operation. If the first pressing head 5 is extended forward only when sealing, and then retracted after completing the sealing, there will be a retracted space for the film package to separate from the area where the first pressing head 5 is located under the action of gravity. Therefore, the connecting rod assembly 4 is configured to be composed of the first push rod 41, the connecting rod seat 42 and the second push rod 43. The zigzag structure is set up, and the connecting rod seat 42 is rotatably connected to the bridge plate 45. The left and right ends of the bridge plate 45 are fixed on the two sets of wall panels 1, which plays a role of stable fixation. The other end of the first push rod 41 is connected to the push plate 23, and the other end of the second push rod 43 is connected to the push head 44. Therefore, when the first cylinder 3 pulls back, the push plate 23 pulls back the first push rod 41, forcing the connecting rod seat 42 to rotate, and the end of the connecting rod seat 42 connected to the second push rod 43 is pushed forward, so that the push head 44 pushes the first pressure head 5 to move in the direction of the second pressure head 7, and the first cylinder 3 pulls back and also pulls back the second pressure head 7, so that the first pressure head 5 and the second pressure head 7 move in opposite directions and abut against each other, which can provide a greater sealing force.

[0031] Since the relative positions of the first pressing head 5 and the second pressing head 7 cannot be exactly aligned during the assembly of the device, and the sealing pressing force requirements for different sauce bags are not completely consistent, it is necessary to adjust the relative positions of the first pressing head 5 and the second pressing head 7. The left and right extensions 211 of the fixing plate 21 are fitted in the limiting long hole and can move left and right. At this time, the front and rear positions of the fixing plate 21 are adjusted. Since the position of the connecting rod seat 42 is fixed, the fixing plate 21 moves to the left, which will increase the distance that the first pressing head 5 is pushed to the right. At the same time, the movement of the fixing plate 21 will also cause the second pressing head 7 to retract toward the direction of the first pressing head 5. Therefore, the left movement of the fixing plate 21 can reduce the distance between the first pressing head 5 and the second pressing head 7, and vice versa. In order to fix the position of the adjusted fixing plate 21, the distance between the first adjustment hole 212 and the second adjustment hole 13 can be adjusted by passing the stud through the adjustment seat 12 and the extension 211 on the wall panel 1.

[0032] The sealing requires heating of the sealing portion to force the plastic to melt and bond. Therefore, a second cylinder 81 is set on the rear plate 63. The second cylinder 81 drives the pressing plate 82, and the pressure column 83 on the pressing plate 82 pushes the heating wire 84 to move in the direction of the first pressing head 5 until the heating wire 84 pushes the film to abut against the pressure pad 51 on the first pressing head 5 to complete the heating and melting of the seal. After the melting and bonding is completed, the second cylinder 81 is started to return the heating wire 84 to the second pressing head 7. Since the sealing melting does not require too much pressing force, only the heating wire 84 and the pressure pad 51 need to abut. Therefore, the second cylinder 81 is a group of small cylinders and will not have much impact on energy consumption.

[0033] The beneficial effect of the utility model is that by starting the first cylinder 3, the second pressure head 7 is moved toward the first pressure head 5 during the pullback process, and the first pressure head 5 is pushed out under the action of the connecting rod of the connecting rod assembly 4, so that the first pressure head 5 and the second pressure head 7 move toward each other and abut against each other, forming a greater sealing force, and the strokes of the two are close. After the film is sealed, the first pressure head 5 and the second pressure head 7 will both move away from the film, so that the film is separated from the area where the first pressure head 5 and the second pressure head 7 are located under the action of gravity, avoiding the film from sticking to the original place after the sealing is completed, causing the subsequent sealed sauce bag to burst, and the melting of the seal is achieved by the second cylinder 81 pushing the heating wire 84 to abut against the pressure pad 51. The device can save the use of a group of large cylinders and save energy consumption.

[0034] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
