Disclosure of Invention
The invention aims to provide a heat sealing device for plastic packaging bags, which solves the problem that the plastic packaging bags are adhered to a heat sealing knife after heat sealing.
In order to achieve the purpose, the invention adopts the following technical scheme: the plastic packaging bag heat-sealing device comprises a top frame, a heat-sealing cutter and a heat-sealing table, wherein the top frame is positioned above the heat-sealing table, a lifting cylinder is fixedly connected onto the top frame, a cylinder rod of the lifting cylinder faces downwards, a transversely arranged fixing plate is fixedly connected onto a cylinder rod of the lifting cylinder, the heat-sealing cutter is fixedly connected onto the lower surface of the fixing plate, two bag pressing mechanisms are arranged on the fixing plate and are positioned on two sides of the heat-sealing cutter, each bag pressing mechanism comprises a sliding rod vertically connected onto the fixing plate in a sliding manner and a bag pressing part positioned on the bottom of the sliding rod, and a first pressure spring is connected between each bag pressing part and the fixing plate; the bag pressing part comprises a pressing block.
The principle and the advantages of the scheme are as follows: the lifting cylinder is used for driving the fixing plate to vertically move, and when the fixing plate vertically moves, the fixing plate drives the heat-sealing knife to vertically move, so that feeding and retracting of the heat-sealing knife are achieved. And the bag pressing mechanism on the fixing plate is used for pressing the packaging bag on the heat sealing table. The sliding rod is connected on the fixing plate in a sliding mode, so that the bag pressing portion can move vertically. When the lifting cylinder drives the fixing plate to move downwards to carry out heat sealing on the packaging bag, the bag pressing portion presses the packaging bag on the heat sealing table, and meanwhile, the fixing plate and the sliding rod slide relatively, so that the bag pressing portion is pressed on the heat sealing table without influencing downward movement of the heat sealing knife, and the heat sealing knife can normally move downwards along with the fixing plate to carry out heat sealing on the packaging bag on the heat sealing table; when the fixed plate moves downwards, the fixed plate compresses the first pressure spring. After the heat-seal finishes, lift cylinder drive fixed plate rebound, the fixed plate drives the sealing cutter rebound this moment, because first pressure spring is in the state of compression, therefore during the fixed plate rebound, the fixed plate can not drive and press bag portion rebound at once, press bag portion to press down on the wrapping bag under the pressure effect of first pressure spring, the wrapping bag can not follow the sealing cutter rebound like this, thereby it follows the sealing cutter rebound to glue on the sealing cutter to have avoided the wrapping bag heat-seal back, need not the manual work and additionally take off the wrapping bag from the sealing cutter, in the sealing cutter rebound in-process, just can realize the separation of sealing cutter and wrapping bag, and easy operation is convenient. After the fixed plate upwards moved a section of distance, deformation can be resumeed to first pressure spring, and the fixed plate drives through first pressure spring and presses bag portion rebound and keep away from the heat-seal platform this moment, presses bag portion can not hinder the change of the epaxial wrapping bag of heat-seal like this.

Referring to fig. 4, in the present embodiment, a plurality of sleeved pipes 22 are disposed at the tip of the pawl 17, the sleeved pipes 22 are sequentially sleeved together from left to right, the diameter of the left sleeved pipe 22 is smaller than the diameter of the right sleeved pipe 22, and the adjacent sleeved pipes 22 can slide relative to each other, so that the tip of the pawl 17 can extend and retract along the length direction of the pawl 17. It is easy to understand that in order to limit the sliding distance of the sleeved pipes 22 and prevent the adjacent sleeved pipes 22 from being separated when the tips of the pawls 17 are extended, a stopper may be disposed between the adjacent sleeved pipes 22.
As shown in fig. 4, a first electromagnet 21 is fixedly connected to the inside of the pawl 17 through a screw, a second pressure spring 20 is connected between the first electromagnet 21 and the tip end of the pawl 17, and the tip of the pawl 17 is made of an iron material, so that the tip end of the pawl 17 can be attracted by the first electromagnet 21 under the action of magnetic force when the first electromagnet 21 is energized.

A button 5 for simultaneously controlling the first electromagnet 21 and the second electromagnet 19 is arranged on the outer side of the fixing plate 3, namely the button 5, the first electromagnet 21 and the second electromagnet 19 are connected in series, the button 5 is electrically connected with a power supply, the button 5 is fixed on the rack through a screw, the button 5 is positioned above the heat sealing table 13, and a control rod 6 for pressing the button 5 is welded on the fixing plate 3; after the rotating roller 11 moves upward and is separated from the heat-sealing stage 13, the lever 6 presses the push button 5. The rotating roller 11 is lower than the bottom end of the heat seal knife 12.
The specific implementation process is as follows: the packaging bag is placed on the heat sealing table 13, the lifting cylinder 2 is started, the lifting cylinder 2 drives the fixing plate 3 to vertically move downwards, when the fixing plate 3 vertically moves, the fixing plate 3 drives the heat sealing knife 12 and the pressing block 9 to move downwards, and the pressing block 9 drives the rotating rod 10 to move downwards. When the rotating roller 11 on the bottom end of the rotating rod 10 abuts against the heat-sealing table 13 first, the two rotating rods 10 rotate along with the downward movement of the fixing plate 3, the rotating rod 10 on the left side rotates clockwise, the rotating rod 10 on the right side rotates counterclockwise, and the bottom ends of the two rotating rods 10 are away from each other. Taking the left rotating lever 10 as an example: referring to fig. 2, when the rotating rod 10 rotates, the rotating rod 10 drives the rotating tube 16 to rotate on the fixed block, and the pawl 17 on the rotating tube 16 slips on the latch 18, so that the pawl 17 cannot be latched on the latch 18, the rotating tube 16 can normally rotate, and when the rotating tube 16 rotates, a first torsion spring between the rotating tube 16 and the pressing block 9 stores force. When the bottom of two dwang 10 was kept away from each other, two live-rollers 11 on the dwang 10 bottom rolled on heat-seal platform 13, and two live-rollers 11 were kept away from each other to it is flat to both sides with the wrapping bag on the heat-seal platform 13 is even, avoids the heat-seal position fold of wrapping bag.
As the fixing plate 3 continues to move downward, the slide bar 7 moves upward relative to the fixing plate 3, the first compression spring 8 is compressed, the heat seal knife 12 is inserted into the insertion groove 14, and the heat seal knife 12 heat-seals the packaging bag on the heat seal table 13. After the heat sealing is finished, the lifting cylinder 2 drives the fixing plate 3 to move upwards, the fixing plate 3 drives the heat sealing knife 12 to move upwards at the moment, and the first pressure spring 8 is in a compressed state, so that when the fixing plate 3 moves upwards, the fixing plate 3 cannot drive the pressing block 9 to move upwards at once, the pressing block 9 cannot move under the pressure action of the first pressure spring 8, the sliding rod 7 slides downwards relative to the fixing plate 3, the rotating roller 11 is still pressed on a packaging bag on the heat sealing table 13 at the moment, the packaging bag cannot move upwards along with the heat sealing knife 12, the situation that the packaging bag is stuck on the heat sealing knife 12 and moves upwards along with the heat sealing knife 12 after heat sealing is avoided, the packaging bag is not required to be taken off from the heat sealing knife 12 additionally manually, in the process that the heat sealing knife 12 moves upwards, the separation of the heat sealing knife 12 and the packaging bag can be realized, and the operation is simple and convenient.
Meanwhile, during the upward movement of the fixed plate 3, the rotating pipe 16 tends to rotate in the opposite direction under the elastic force of the first torsion spring, and the rotating rod 10 tends to rotate in the opposite direction. Taking the left rotating lever 10 as an example, the pawl 17 is clamped on the latch 18 at this time, so that the rotating tube 16 is in a locked state, and therefore, the rotating tube 16 in fig. 2 does not rotate counterclockwise, and even if the first torsion spring has a certain elastic force, the rotating tube 16 does not reversely drive the rotating lever 10 to swing. Therefore, the rotating rods 10 on the two sides of the heat sealing knife 12 are in a static state and cannot rotate reversely, the phenomenon that the packaging bags after heat sealing become folded due to the fact that the bottom ends of the rotating rods 10 on the two sides of the heat sealing knife 12 are close to each other when the rotating roller 11 does not leave the heat sealing table 13 in the process that the heat sealing knife 12 moves upwards is avoided, the packaging bags after heat sealing can still be in a flat state, and follow-up processing of the packaging bags is facilitated.
After fixed plate 3 upwards moved a section distance, deformation can be resumeed to first pressure spring 8, and fixed plate 3 drives briquetting 9 rebound through first pressure spring 8 this moment, and briquetting 9 drives dwang 10 and upwards removes and keep away from heat-seal platform 13, and the bottom of dwang 10 can not press on heat-seal platform 13 and hinder the change of the wrapping bag on the heat-seal platform 13 like this. Meanwhile, after the fixed plate 3 moves upwards to the limit position, the control rod 6 on the fixed plate 3 presses the button 5, the button 5 controls the first electromagnet 21 and the second electromagnet 19 to be electrified, the first electromagnet 21 and the second electromagnet 19 both generate magnetism, the first electromagnet 21 attracts the tip end of the pawl 17, so that the pawl 17 is shortened, the pawl 17 is not abutted to the latch 18, meanwhile, the second electromagnet 19 attracts the pawl 17, the pawl 17 rotates under the attraction of the second electromagnet 19, the pawl 17 enables the second torsion spring to store force, the pawl 17 swings on the rotating tube 16 in the direction far away from the latch 18, therefore, the pawl 17 cannot be clamped on the latch 18, the rotating tube 16 resets under the elastic force of the first torsion spring, and the rotating tube 16 drives the rotating rod 10 to rotate and reset to the initial position.
When the fixed plate 3 moves downwards again, the control rod 6 is far away from the button 5, the button 5 is not pressed any more, the first electromagnet 21 and the second electromagnet 19 are powered off automatically, the pawl 17 swings towards the direction close to the latch 18 under the action of the elastic force of the second torsion spring, and meanwhile, the pawl 17 is lengthened under the action of the second compression spring 20, so that the pawl 17 is clamped on the latch 18 again. Repeating the above process to complete the heat sealing of the next packaging bag.
The above description is only an example of the present invention, and the general knowledge of the known specific technical solutions and/or characteristics and the like in the solutions is not described herein too much. It should be noted that, for those skilled in the art, without departing from the technical solution of the present invention, several variations and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
