Description

Technical Field

[0001] The invention belongs to the technical field of ziplock bag manufacturing, and in particular relates to a continuous feeding device for ziplock bag production. Background Art

[0002] Ziplock bags, also known as pressed and automatically sealed packaging bags, are a common plastic packaging product. There are many kinds of materials for making ziplock bags, the most common ones are polyethylene, polypropylene and nylon. Ziplock bags can achieve a tight sealing effect through special sealing design, effectively preventing items from scattering, moisture-proof, odor-proof, waterproof, and insect-proof. At the same time, they have good transparency, so you can clearly see the internal items, which is convenient for management and retrieval. They are mainly used for food packaging, clothing storage, and electronic product packaging. The common loading method for ziplock bags during manufacturing is roll film loading, which is to install the rolled plastic film on a specific unwinding device, and use a power source such as a motor drive to make the roll rotate, thereby releasing the film. This method is suitable for large-scale production and can continuously and stably provide film materials to ensure production efficiency.

[0003] In the actual production process of ziplock bags, the feeding of roll film is a key link. When a roll of film is gradually exhausted during use, problems will arise. Due to the current production process and equipment limitations, once a roll of film is used up, the equipment on the entire production line, including the bag making machine and other related auxiliary equipment, needs to stop. This is because the interruption of film supply will cause the bag making machine to be unable to continue to produce ziplock bags normally, and if other equipment is not stopped in time, a series of problems such as material accumulation and reduced processing accuracy may occur. After the equipment is stopped, the operator needs to quickly replace a roll of new film. This replacement process requires the new roll of film to be clamped to ensure that it is firmly fixed on the equipment to prevent it from loosening or slipping during the unwinding process. This not only requires the operator to have skilled operating skills, but also requires a lot of time and energy to adjust the position and strength of the clamping. During the entire process of replacing the film, the production line is stagnant, which greatly affects the production efficiency. The originally continuous and stable production process is interrupted, resulting in a delay in production progress.

[0004] Therefore, it is urgent to provide a continuous feeding device for ziplock bag production to solve the above problems. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a continuous feeding device for the production of ziplock bags.

The setting of the mounting holes facilitates the disassembly and installation of the rolls. The matching setting of the guide groove and the guide plate makes the movable plate more stable when moving. After the cross shaft is inserted into the cross hole at the end of the roll shaft, the motor is started, and the transmission rod rotates to drive the roll shaft to rotate through the cross shaft, thereby performing the film unwinding work.

[0012] Through the above technical scheme, the installation mechanism is used for disassembly and installation of the first reel and the second reel, the reel shaft is placed inside the lower clamp block and the upper clamp block and fits with the ball, when the reel shaft rotates, the ball follows the rotation, thereby reducing the friction between the reel shaft and the inner walls of the lower clamp block and the upper clamp block, and increasing the rotation speed of the first reel and the second reel. The setting of the first guide rod enables the upper clamp block to move upward stably, thereby temporarily disengaging from the surface of the lower clamp block, making it easier to place the reel shaft inside the lower clamp block.

[0013] The present invention is further configured as follows: a socket is provided on the surface of the lower clamping block, a plug block is fixedly connected to the surface of the upper clamping block, the plug block is movably inserted in the socket, a symmetrical clamping block is slidably connected in the socket, the clamping block is slidably connected to the surface of the plug block, a push rod is fixedly connected to one side of the clamping block, a receiving groove is provided on both sides of the socket, the clamping block is slidably connected in the receiving groove, a symmetrical yielding groove is provided on the surface of the lower clamping block, the push rod is slidably connected in the yielding groove, a top plate is fixedly installed on the end of the first guide rod, a first spring is fixedly installed on the lower surface of the top plate, and the other end of the first spring is fixedly connected to the surface of the upper clamping block.

[0014] Through the above technical scheme, when a new reel needs to be replaced, the two push rods are pushed to the left and right sides, and the push rods drive the card block to move away from the surface of the plug block, canceling the limit on the plug block, and the upper clamp block moves away from the surface of the lower clamp block and moves up to the top plate under the action of the first spring. A certain space is formed between the lower clamp block and the upper clamp block to facilitate the placement of the reel shaft.

[0016] Through the above technical scheme, the bonding mechanism realizes the bonding between the surface film of the first roll and the surface film of the second roll. When the unwinding of the surface film of the second roll is about to end, the power supply is started. According to the principle of electromagnetic induction, the metal block inside the coil will be magnetic. The metal block attracts the magnetic stone, so that the magnetic stone can move down, and the front end of the surface film of the first roll is located below the magnetic stone. When the magnetic stone moves down, the surface film of the first roll moves down and fits with the tail end of the surface film of the second roll. The bonding layer makes the two films bonded to each other and form a whole, so as to realize continuous feeding of the films. The auxiliary roller provides auxiliary work to make the unwinding of the surface film of the first roll smoother. The setting of the support plate enables the front end of the surface film of the second roll to be placed, so as to realize the bonding between the tail end of the surface film of the first roll and the front end of the surface film of the second roll.

[0017] The present invention is further configured as follows: a connecting column is fixedly installed on the surface of the magnetic stone, a limiting ring is fixedly installed on the end of the connecting column, a sleeve is fixedly installed on the lower surface of the support frame, the connecting column and the limiting ring are slidably connected inside the sleeve, a second spring is fixedly installed on the surface of the limiting ring, the end of the second spring is fixedly connected to the lower surface of the support frame, a symmetrical second guide rod is fixedly installed on the surface of the magnetic stone, and the second guide rod is slidably connected inside the support frame.

[0018] Through the above technical solution, when the magnetic stone moves down to achieve the bonding of the surface film of the first roll and the surface film of the second roll, the connecting column and the limit ring move down at the same time inside the sleeve. At this time, the second spring is in a stretched state, the power is cut off, the metal block loses its magnetism, the second spring rebounds, and the magnetic stone is pulled back to the initial position, waiting for the next use.

The third guide rod makes the push plate more stable when moving, and the setting of the fourth spring enables the push plate to return to its initial position.

[0023] The present invention is further configured as follows: the first roll and the second roll are detachably mounted inside the fixed plate and the movable plate, and the surface film of the first roll and the surface film of the second roll are movably attached to each other through an adhesive layer.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] See also Figure 1-Figure 10 The present application provides a continuous feeding device for producing ziplock bags, comprising a bottom plate 1, on the surface of which a first reel 2 and a second reel 3 are detachably mounted.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a cylinder 11 is fixedly mounted on the surface of the base plate 1, a fixed plate 12 is fixedly mounted on the surface of the base plate 1, a mounting hole 121 is provided on the surface of the fixed plate 12, a movable plate 13 is slidably connected to the surface of the base plate 1, an end of the cylinder 11 is fixedly connected to the surface of the movable plate 13, a guide plate 131 is fixedly mounted on the lower surface of the movable plate 13, a guide groove 132 is provided on the surface of the base plate 1, the guide plate 131 is slidably connected inside the guide groove 132, a plurality of motors 14 are fixedly mounted on the surface of the fixed plate 12, an output end of the motor 14 is transmission-connected to a transmission rod 141, and a cross shaft 142 is fixedly mounted on the end of the transmission rod 141.

[0031] In this embodiment, the movable plate 13 can be further moved on the surface of the base plate 1 by the cylinder 11, so as to adjust the distance between the movable plate 13 and the fixed plate 12, which is convenient for clamping and fixing rolls of different sizes. The setting of the mounting hole 121 is convenient for the disassembly and installation of the roll. The matching setting of the guide groove 132 and the guide plate 131 makes the movable plate 13 more stable when moving. After the cross shaft 142 is inserted into the cross hole 331 at the end of the roll shaft 33, the motor 14 is started, and the transmission rod 141 rotates to drive the roll shaft 33 to rotate through the cross shaft 142, thereby performing the unwinding work of the film 31.

[0032] like Figure 2 and Figure 4 As shown, a film 31 is wound around the surface of the first reel 2 and the second reel 3, and an adhesive layer 32 is fixedly installed on the ends of the film 31. A reel shaft 33 is fixedly installed inside the first reel 2 and the third reel 3. The reel shaft 33 is movably inserted into the mounting hole 121, and a cross hole 331 is opened at one end of the reel shaft 33. The cross shaft 142 can be detachably installed inside the cross hole 331.

[0033] Furthermore, in this embodiment, the film 31 is used to manufacture ziplock bags. The setting of the adhesive layer 32 can bond the front end of the film 31 on the surface of the first reel 2 with the rear end of the film 31 on the second reel 3, thereby realizing continuous loading of the film 31. After the cross shaft 142 is inserted into the cross hole 331, the reel shaft 33 can be rotated by the motor 14, and the first reel 2 and the second reel 3 can be further rotated to unwind the film 31.

[0034] like Figure 2 and Figure 4 As shown, the first reel 2 and the second reel 3 are detachably mounted inside the fixed plate 12 and the movable plate 13 , and the surface film 31 of the first reel 2 and the surface film 31 of the second reel 3 are movably attached via the adhesive layer 32 .

[0035] In this embodiment, the distance between the movable plate 13 and the fixed plate 12 can be adjusted to realize the unwinding of films 31 of different sizes. The adhesive layer 32 enables the film 31 between the two rolls to form a whole through bonding, thereby realizing continuous feeding of the film 31 and improving the production efficiency of the ziplock bag.

[0036] A mounting mechanism 4 for fixing the first reel 2 and the second reel 3 is fixedly mounted on the surface of the bottom plate 1 , a bonding mechanism 5 is fixedly mounted on one side of the bottom plate 1 , and a fixing mechanism 6 is fixedly mounted on the surface of the bonding mechanism 5 .

[0037] like Figure 2 and Figure 7 As shown, the mounting mechanism 4 includes a lower clamping block 41, which is fixedly mounted on the inner wall of the fixed plate 12, and an upper clamping block 42 is detachably mounted on the surface of the lower clamping block 41. Through grooves 411 are provided on the surfaces of the lower clamping block 41 and the upper clamping block 42, and a plurality of balls 412 are rotatably connected inside the through grooves 411, and the balls 412 are movably fitted with the surface of the reel shaft 33, and a plurality of first guide rods 43 are fixedly connected to the surface of the lower clamping block 41, and the upper clamping block 42 is slidably connected to the surface of the first guide rods 43.

[0038] Furthermore, in this embodiment, the mounting mechanism 4 is used for disassembly and installation of the first reel 2 and the second reel 3. The reel shaft 33 is placed inside the lower clamp block 41 and the upper clamp block 42 and fits with the ball 412. When the reel shaft 33 rotates, the ball 412 rotates accordingly, thereby reducing the friction between the reel shaft 33 and the inner walls of the lower clamp block 41 and the upper clamp block 42, thereby increasing the rotation speed of the first reel 2 and the second reel 3. The provision of the first guide rod 43 enables the upper clamp block 42 to move upward stably, thereby temporarily disengaging from the surface of the lower clamp block 41, thereby facilitating the placement of the reel shaft 33 inside the lower clamp block 41.

[0039] like Figure 7 and Fig.10 As shown, a socket 413 is provided on the surface of the lower clamping block 41, and a plug block 421 is fixedly connected to the surface of the upper clamping block 42. The plug block 421 is movably inserted into the socket 413. A symmetrical clamping block 414 is slidably connected to the inside of the socket 413. The clamping block 414 is slidably connected to the surface of the plug block 421. A push rod 415 is fixedly connected to one side of the clamping block 414. Receiving grooves 416 are provided on both sides of the socket 413. The clamping block 414 is slidably connected inside the receiving groove 416. Symmetrical yielding grooves 417 are provided on the surface of the lower clamping block 41. The push rod 415 is slidably connected inside the yielding groove 417. A top plate 431 is fixedly installed on the end of the first guide rod 43. A first spring 432 is fixedly installed on the lower surface of the top plate 431. The other end of the first spring 432 is fixedly connected to the surface of the upper clamping block 42.

[0040] Furthermore, in this embodiment, when a new reel needs to be replaced, the two push rods 415 are pushed to the left and right sides, and the push rods 415 drive the block 414 to move away from the surface of the plug block 421, canceling the limit on the plug block 421, and the upper clamping block 42 is moved away from the surface of the lower clamping block 41 and moved up to the top plate 431 under the action of the first spring 432. A certain space is formed between the lower clamping block 41 and the upper clamping block 42 to facilitate the placement of the reel shaft 33. The two ends of the reel shaft 33 are placed inside the lower clamping block 41 respectively. At this time, the cross hole 331 at one end of the reel shaft 41 and the cross shaft 142 are simultaneously connected, the upper clamping block 42 is pressed, and the plug block 421 is reinserted into the socket 413. The push rod 415 is moved to make the block 414 move back to the surface of the plug block 421 to limit the plug block 421 again, thereby clamping the reel shaft 33 without affecting the rotation of the reel shaft 33 itself.

[0042] The present embodiment further, the bonding mechanism 5 realizes the bonding between the surface film 31 of the first roll 2 and the surface film 31 of the second roll 3. When the unwinding of the surface film 31 of the second roll 3 is about to end, the power supply 54 is started. According to the principle of electromagnetic induction, the metal block 53 inside the coil 531 will be magnetic. The metal block 53 attracts the magnetic stone 52, so that the magnetic stone 52 can move down. The front end of the surface film 31 of the first roll 2 is located below the magnetic stone 52. When the magnetic stone 52 moves down, the surface film 31 of the first roll 2 moves down and fits with the tail end of the surface film 31 of the second roll 3. The adhesive layer 32 enables the two films 31 to be bonded and form a whole, so as to realize continuous feeding of the film 31. The auxiliary roller 55 provides auxiliary work, so that the unwinding of the surface film 31 of the first roll 2 is smoother. The setting of the support plate 511 enables the front end of the surface film 31 of the second roll 3 to be placed, so as to realize the bonding between the tail end of the surface film 31 of the first roll 2 and the front end of the surface film 31 of the second roll 3.

[0044] Furthermore, in this embodiment, when the magnetic stone 52 moves downward to achieve the bonding of the surface film 31 of the first reel 2 and the surface film 31 of the second reel 3, the connecting column 521 and the limiting ring 522 move downward simultaneously inside the sleeve 523. At this time, the second spring 524 is in a stretched state, the power supply 54 is cut off, the metal block 53 loses its magnetism, the second spring 524 rebounds, and the magnetic stone 52 is pulled back to the initial position, waiting for the next use. The setting of the second guide rod 525 makes the magnetic stone 52 more stable when moving up and down.

The pull rod 62 is released, and the extrusion plate 63 squeezes the front end of the film 31 under the action of the third spring 64 to prevent the front end of the film 31 from falling off, thereby facilitating subsequent work.

The connecting plates 81 are internally threadedly connected with a screw rod 82, and the end of the screw rod 82 is movably fitted with a push plate 83. A third guide rod 84 is fixedly installed on the surface of the push plate 83, and the third guide rod 84 is slidably connected to the inside of the connecting plate 81. A fourth spring 85 is fixedly installed on the surface of the push plate 83, and the end of the fourth spring 85 is fixedly connected to the inner wall of the connecting plate 81. The third guide rod 84 runs through the inside of the fourth spring 85, and symmetrical guide rollers 86 are rotatably connected to the two connecting plates 81.

[0049] Furthermore, in this embodiment, when the screw 82 is rotated, the screw 82 squeezes the push plate 83 to move on the surface of the conveyor belt 7, so that the distance between the two push plates 83 can be adjusted, which is convenient for correcting the deviation of films 31 of different sizes, ensuring that the film 31 keeps moving in a horizontal direction and preventing the film 31 from detaching from the surface of the conveyor belt 7. The third guide rod 84 makes the push plate 83 more stable when moving, and the setting of the fourth spring 85 enables the push plate 83 to return to its initial position.

[0050] The working principle of this embodiment is as follows: first, the distance between the movable plate 13 and the fixed plate 12 is adjusted according to the size of the film 31, and the first roll 2 and the second roll 3 are placed between the movable plate 13 and the fixed plate 12, and the second roll 3 is unwinding first, and at the same time, the pull rod 62 is pulled, and the squeezing plate 63 is away from the side of the magnetic stone 52, and the front end of the film 31 on the surface of the first roll 2 is placed in the middle of the side of the magnetic stone 52 and the side of the squeezing plate 63. When the film 31 on the surface of the second roll 3 is about to end, the power supply 54 is started, and the power is turned on. According to the principle of electromagnetic induction, the metal block 53 inside the coil 531 will be magnetic, and the metal block 53 attracts the magnetic stone 52, so that the magnetic stone 52 can move down, and the front end of the film 31 on the surface of the first roll 2 is located below the magnetic stone 52. When the magnetic stone 52 moves down, the film 31 on the surface of the first roll 2 moves down and fits with the tail end of the film 31 on the surface of the second roll 3. The adhesive layer 32 makes the two films 31 bonded to form a whole, so that the film 31 is continuously fed, and then the unwinding of the second roll is completed. The roller 3 is replaced by pushing the two push rods 415 to the left and right sides, and the push rods 415 drive the clamping block 414 to move away from the surface of the plug block 421, canceling the limit of the plug block 421, and the upper clamping block 42 is away from the surface of the lower clamping block 41 under the action of the first spring 432 and moves up to the top plate 431, and a certain space is formed between the lower clamping block 41 and the upper clamping block 42 to facilitate the placement of the reel shaft 33, and the two ends of the reel shaft 33 are placed in the lower clamping block 41 respectively. At this time, the cross hole 331 at one end of the reel shaft 41 and the cross shaft 142 are simultaneously After the docking is completed, the upper clamping block 42 is pressed, the plug block 421 is reinserted into the socket 413, and the push rod 415 is moved to move the clamping block 414 back to the surface of the plug block 421 to limit the plug block 421 again, and the reel shaft 33 is re-clamped. At the same time, the front end of the surface film 31 of the second reel 3 is placed on the surface of the support plate 511. When the surface film 31 of the first reel 2 is about to end, the power supply 54 is started again to achieve bonding between the tail end of the surface film 31 of the first reel 2 and the front end of the surface film 31 of the second reel 3.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
