Description

Technical Field

[0001] The utility model relates to the technical field of flat bag cutting and heat sealing, in particular to a flat bag cutting and heat sealing integrated device. Background Art

[0002] Flat bags are a common type of bag and are widely used in the market. When a bag making machine makes a flat bag, it is still in one piece. Cutting and heat-sealing equipment is needed to cut the flat bag into the required size before it can be shipped. For example, in the patent number "CN212021811U" and the patent name "Heat-sealing and cutting mechanism of a flat bag making machine", a heating copper tube is provided on the front side of the bottom of the lifting block. The heating copper tube is heated by an electrode. The bottom of the heating copper tube is coated with thermal conductive paper, which is graphite paper. The end of the thermal conductive paper is wrapped around a thermal conductive paper roller on the bag making machine frame. The heating copper tube is used to replace the hot pressing block to heat and press the flat bag. A cutter is arranged at the rear side of the bottom of the lifting block. A bag sealing head is also arranged at the rear side of the cutter. The top of the bag sealing head is fixed on the lifting block. When the flat bag is rolled up by the rolling mechanism, the lifting block is pressed down. The flat bag first contacts with the heat-conducting paper for heating. After the heating is completed, the cutter cuts off the flat bag, and then the bag sealing head seals the mouth. In this way, hot pressing, cutting and bag sealing can be completed at the same time, which reduces the overall length of the bag making machine and improves the production efficiency. However, the above structure still has the following problems in actual use:

[0003] The above structure directly sends out the flat bags after cutting and heat-sealing, and the heat-sealed parts are cooled and formed by natural cooling. However, wrinkles, folds, and rolling may occur during the delivery of the flat bags, which may cause deformation of the heat-sealed parts that have not been cooled, thereby affecting the production quality of the flat bags.

[0004] Therefore, we proposed a flat bag cutting and heat sealing integrated equipment that can solve the above problems well. Utility Model Content

[0005] The purpose of the utility model is to provide a flat bag cutting and heat-sealing integrated device to solve the problem raised in the above background technology that after the flat bags on the market are cut and heat-sealed, the heat-sealed parts cannot be cooled and formed, which easily leads to deformation of the heat-sealed parts, thereby affecting the production quality of the flat bags.

[0006] To achieve the above object, the utility model provides the following technical solution: a flat bag cutting and heat-sealing integrated device, comprising a platform, a U-shaped plate is welded and fixed to the upper surface of the platform, and a base is welded and fixed to the upper surface of the platform;

[0007] It also includes: a cavity is welded and fixed on the inner wall of the upper surface of the U-shaped plate, and a thrust rod is slidably connected inside the cavity, and a first magnet is fixed on the upper end surface of the thrust rod, and a second magnet is fixed on the inner wall of the cavity above the first magnet, and the right side of the cavity is connected to an air intake pipe, and the lower end of the air intake pipe is connected to a diverter pipe, and both ends of the diverter pipe are fixed to the U-shaped plate, and air blowing heads are evenly distributed on the lower surface of the diverter pipe.

[0008] Preferably, the thrust rod is arranged in an "I"-shaped structure, and a sealing ring is bonded to the outer side surface of the upper end of the thrust rod.

[0009] Preferably, a cylinder is installed on the upper surface of the U-shaped plate, and the lower end of the cylinder passes through the U-shaped plate and is fixed to the mounting plate. A heat sealing strip is fixedly installed on the right side of the lower surface of the mounting plate, and a cutting knife is installed on the left side of the lower surface of the mounting plate.

[0010] Preferably, a clamping hole is opened on the left side surface of the cutting knife, and a clamping rod is clamped inside the clamping hole, and a connecting rod is welded and fixed to the left side of the lower surface of the clamping rod, and the lower end of the connecting rod passes through the lower surface of the mounting plate, and a sliding connection is formed between the connecting rod and the mounting plate, and the left end of the clamping rod is fixed to the reset spring, and the left end of the reset spring is fixed to the mounting plate.

[0011] Preferably, a servo motor is fixed by bolts on the rear side of the U-shaped plate, and the output end of the servo motor is fixed to the conveying roller.

[0012] Preferably, 8 groups of conveying rollers are provided, and the front ends of the conveying rollers are connected to the U-shaped plate bearings, and a driving sprocket is fixed to the outer side surface of one group of conveying rollers, and a chain is sleeved on the outer side surface of the driving sprocket.

[0013] Preferably, a driven sprocket is meshed with the inner side of the right side surface of the chain, and a conveying roller is fixed in the middle of the driven sprocket, and the driving sprocket forms a linkage structure with the driven sprocket through the chain.

[0014] Compared with the prior art, the beneficial effects of the utility model are: the flat bag cutting and heat-sealing integrated equipment not only realizes the effect of cooling and molding the material at the heat-sealed part of the flat bag, thereby avoiding the deformation at the heat-sealed part, effectively improving the production quality of the flat bag, but also facilitates the replacement of the cutting knife, and the replacement process is time-saving and labor-saving, greatly saving the replacement time and improving the production efficiency. The specific contents are as follows:

[0015] (1) The cylinder drives the mounting plate to move upward, so that the mounting plate squeezes the thrust rod, which makes the thrust rod slide into the cavity, and squeezes the air in the cavity into the air inlet pipe, enters the diverter pipe through the air inlet pipe, and is blown out by the blowing head through the diverter pipe, thereby achieving the effect of cooling and molding the material at the heat seal of the flat bag, thereby avoiding the deformation of the heat seal, and effectively improving the production quality of the flat bag;

[0016] (2) Furthermore, when the thrust rod is no longer squeezed, the repulsive force between the first magnet and the second magnet causes the thrust rod to slide downward, thereby resetting the thrust rod to facilitate the next use;

[0017] (3) The connecting rod is pushed to the left side, so that the connecting rod drives the clamping rod and the clamping hole to separate, and a new cutting knife is replaced. Then, the cutting knife is fitted with the mounting plate. Through the elastic force of the reset spring, the right end of the clamping rod is engaged with the clamping hole, and the cutting knife is limited, so that the cutting knife is easily replaced. The replacement process is time-saving and labor-saving, which greatly saves the replacement time and improves the production efficiency.

[0018] (4) A linkage structure is formed between the driving sprocket and the driven sprocket, so that the servo motor drives the driving sprocket to rotate while the driven sprocket rotates together. The rotation of the driven sprocket drives other conveying rollers to rotate together, which greatly saves power loss, reduces costs, and saves resources;

[0019] (5) By setting up multiple sets of conveying rollers, the conveying effect of the flat bags can be achieved, so that the flat bags can be conveyed to the bottom of the cutting and heat sealing mechanism for cutting and heat sealing, and the cut and heat-sealed flat bags can be sent out.

[0030] Embodiment 1: In order to solve the problem in the prior art that after the flat bag is cut and heat-sealed, the heat-sealed part cannot be cooled and formed, which easily leads to deformation of the heat-sealed part, thereby affecting the production quality of the flat bag, the following scheme is disclosed, including a platform 1, a U-shaped plate 2 is welded and fixed on the upper surface of the platform 1, and a base 3 is welded and fixed on the upper surface of the platform 1; and further comprising: a cavity 12 is welded and fixed on the inner wall of the upper surface of the U-shaped plate 2, and a thrust rod 1 is slidably connected to the inside of the cavity 12 3, and a first magnet 14 is fixed to the upper end surface of the thrust rod 13, and a second magnet 15 is fixed to the inner wall of the cavity 12 above the first magnet 14, and an air inlet pipe 16 is connected to the right side of the cavity 12, and the lower end of the air inlet pipe 16 is connected to the shunt pipe 17, and both ends of the shunt pipe 17 are fixed to the U-shaped plate 2, and the lower surface of the shunt pipe 17 is evenly spaced with air blowing heads 18, the thrust rod 13 is arranged in an "I" shape, and a sealing ring is bonded to the outer side surface of the upper end of the thrust rod 13;

[0031] The cylinder 4 drives the mounting plate 5 to move upward, so that the mounting plate 5 will squeeze the thrust rod 13, so that the thrust rod 13 slides into the cavity 12, and the air in the cavity 12 is squeezed into the air inlet pipe 16, and the air enters the shunt pipe 17 through the connecting structure between the air inlet pipe 16 and the shunt pipe 17, and the air is shunted into the blowing head 18 through the shunt pipe 17, and then blown out by the blowing head 18, so as to achieve the effect of cooling and forming the material at the heat sealing part of the flat bag, thereby avoiding the deformation at the heat sealing part, effectively improving the production quality of the flat bag, and there is no need to use a separate electric power mechanism to achieve the cooling effect, which greatly reduces the cost of the device, and when the cylinder 4 drives the mounting plate 5 to move downward, the thrust rod 13 is no longer squeezed, and the repulsive force between the first magnet 14 and the second magnet 15 at this time makes the thrust rod 13 slide downward, so as to achieve the reset of the thrust rod 13, which is convenient for the next use;

[0032] Embodiment 2: Different from Embodiment 1, this embodiment facilitates the replacement of the cutting blade 7. Figure 2-Figure 3 , a cylinder 4 is installed on the upper surface of the U-shaped plate 2, and the lower end of the cylinder 4 passes through the U-shaped plate 2 and is fixed to the mounting plate 5, and a heat sealing strip 6 is fixedly installed on the right side of the lower surface of the mounting plate 5, and a cutting knife 7 is installed on the left side of the lower surface of the mounting plate 5, and a clamping hole 8 is opened on the left side of the cutting knife 7, and a clamping rod 9 is clamped inside the clamping hole 8, and a connecting rod 10 is welded and fixed on the left side of the lower surface of the clamping rod 9, and the lower end of the connecting rod 10 passes through the lower surface of the mounting plate 5, and a sliding connection is formed between the connecting rod 10 and the mounting plate 5, and the left end of the clamping rod 9 is fixed to the return spring 11, and the left end of the return spring 11 is fixed to the mounting plate 5;

[0033] The mounting plate 5 is driven to rise and fall by the cylinder 4, so that the cutting knife 7 on the lower surface of the mounting plate 5 and the heat sealing strip 6 can achieve the effect of cutting and heat sealing the flat bag. Moreover, when the cutting knife 7 needs to be replaced, it is only necessary to push the connecting rod 10 to the left side, so that the connecting rod 10 drives the clamping rod 9 to separate from the clamping hole 8, thereby releasing the limit of the cutting knife 7. At this time, the old cutting knife 7 can be replaced and replaced with a new cutting knife 7. Subsequently, the cutting knife 7 and the mounting plate 5 are fitted, and then the connecting rod 10 is loosened. At this time, the elastic force of the reset spring 11 drives the clamping rod 9 to reset, so that the right end of the clamping rod 9 is clamped with the clamping hole 8, thereby limiting the cutting knife 7, so that the cutting knife 7 can achieve the effect of cutting, thereby facilitating the replacement of the cutting knife 7, and the replacement process is time-saving and labor-saving, which greatly saves the replacement time and improves the production efficiency.

[0034] Embodiment 3: Different from Embodiment 2, this embodiment uses a linkage structure formed between the driving sprocket 20, the chain 21 and the driven sprocket 22, so that the conveying roller 23 can achieve the conveying effect. For details, refer to Figure 2 and Figure 6-Figure 7 A servo motor 19 is bolted to the rear side of the U-shaped plate 2, and the output end of the servo motor 19 is fixed to a conveying roller 23.

A driven sprocket 22 is meshed with the inner side of the right side of the chain 21, and a conveying roller 23 is fixed in the middle of the driven sprocket 22. The driving sprocket 20 forms a linkage structure with the driven sprocket 22 through the chain 21;

[0035] And by setting up multiple groups of conveying rollers 23, flat bags can be conveyed, and by starting the servo motor 19, the servo motor 19 drives one group of conveying rollers 23 to rotate, and while the conveying rollers 23 rotate, the driving sprocket 20 is also driven to rotate together, and the chain 21 is moved together by the rotation of the driving sprocket 20. By setting up the chain 21, a linkage structure is formed between the driving sprocket 20 and the driven sprocket 22, so that the driven sprocket 22 rotates together, and the rotation of the driven sprocket 22 drives other conveying rollers 23 to rotate together, thereby achieving the conveying effect of the flat bags, and the tensioning degree of the chain 21 can be ensured by installing a tensioning wheel at a later stage.
