Description

Technical Field

[0001] The invention relates to the technical field of heat sealing equipment, in particular to heat sealing equipment for producing PVC massage pools. Background Art

[0002] The working principle of a high-frequency heat sealer is to use the heating effect of a high-frequency electromagnetic field to heat plastic materials, causing them to soften and bond together. Specifically, a high-frequency power supply generates a high-frequency current, which is transmitted to electrodes in the heat sealing head, forming a high-frequency electromagnetic field. When the heat sealing head contacts the plastic material, the high-frequency electromagnetic field causes the molecules within the plastic material to continuously rub against each other, generating heat, which softens the plastic material and bonds it together. The heat sealing head of a high-frequency heat sealer typically consists of two metal plates with an insulating material sandwiched between them, forming a capacitor. When the high-frequency power supply is operating, the electrodes in the heat sealing head generate a high-frequency current, causing the electric field in the capacitor to continuously change. This changing electric field generates a high-frequency electromagnetic field, which causes the molecules within the plastic material to continuously rub against each other, generating heat, thereby softening and bonding the plastic material together. Traditional technology for plastic bonding has the potential problem of sticking to the heat sealing head. When the heat sealing head moves, it can pull up the plastic product, potentially damaging it or even accidentally separating it from the production line. In addition, the accidental movement of the plastic product can pull up workers, further causing production safety accidents.

The second barrel gear 38 transmits the stationary part 15. The long shaft 36 is sleeved in the through hole opened on the shaft seat 37, and the shaft seat 37 is fixed on one side of the C-shaped air baffle 33.

[0040] The stationary portion 15 includes a flat tube 39, an air box group 40, a dual control shaft 41, a disc gear 42, a power head 43, a folding column frame 44, a third gear 45, a first support shaft 46 and a second support shaft 47. One side of the air box group 40 is connected to the flat tube 39, and the other side of the air box group 40 is fixed with a folding column frame 44. Two through holes are provided on the folding column frame 44, and the first support shaft 46 and the second support shaft 47 are respectively sleeved in the two through holes. One end of the second support shaft 47 is perpendicular to the first support shaft 46, and the second support shaft 47 is perpendicular to the first support shaft 46. 7 and the end of the first support shaft 46 are fixed with bevel gears, the other end of the second support shaft 47 is fixed with a third gear 45, the third gear 45 is engaged with the second cylinder gear 38, one end of the first support shaft 46 is connected to the disk gear 42 by a cylinder gear, the middle of the disk gear 42 passes through the double control shaft 41, one end of the double control shaft 41 is connected to the power head 43, the power head 43 and the long rack 30 are connected, the other end of the double control shaft 41 is connected to the air box group 40, and the sub-plate frame 19 is fixed to one side of the flat tube 39.

[0041] The air box group 40 includes an L-shaped air box 48, a fan 49 and a wind tube 50. One end of the wind tube 50 is connected to the flat tube 39, and the other end of the wind tube 50 is closed, and the closed end is connected to one end of the L-shaped air box 48. The other end of the L-shaped air box 48 is open, and the open end of the L-shaped air box 48 is slidably set in the square cylinder 27. The double-control shaft 41 is sleeved in the through hole opened on the shell of the L-shaped air box 48. The fan 49 is fixed to one end of the double-control shaft 41, and the fan 49 is distributed in the wind tube 50. The power head 43 includes a cylinder gear and a one-way bearing fixed in the middle of the cylinder gear. The inner cylinder on the one-way bearing is fixed to one end of the double-control shaft 41, and the cylinder gear of the power head 43 is engaged with the long rack 30.

[0042] refer to Figures 1 to 4 It is understood that during the falling process of the head plate 14 and the coordination process of the C-shaped pad column 4, the plastic cloth is placed on the top of the C-shaped pad column 4. Before the head plate 14 and the C-shaped pad column 4 are completely docked, the unit component 11 completes its autonomous deformation. Specifically, the roller 22 is pushed in the opposite direction by the C-shaped pad column 4, so that the bevel rack 21 slides obliquely upward, and then transmits the short rack 28 through the first column gear 24 to control the square cylinder 27 to move close to the L-shaped air box 48. At this time, the square cylinder 27 drives the L-shaped air pipe 32, and then drives the C-shaped air baffle 33 through the L-shaped position plate 31. The C-shaped air baffle 33 drives the long rack 30 to move synchronously with the square cylinder 27. Although the long rack 30 and the power head 43 are engaged for transmission, they will not further transmit the dual-control shaft 41 due to the influence of the one-way bearing in the power head 43. The entire unit component 11 is deformed, but no effective transmission is generated.

[0043] After the heat sealing work is completed, the head plate 14 rises, and the roller 22 moves obliquely downward after no support is applied. The entire unit 11 undergoes reverse deformation, and effective transmission is generated during the reverse deformation. Specifically, the square cylinder 27 and the long rack 30 move in the opposite direction synchronously. At this time, the power head 43 reversely drives the double control shaft 41, and the double control shaft 41 drives the disc gear 42 and the fan 49 to rotate. The rotation of the disc gear 42 eventually causes Figure 12 The air nozzle 34 in the middle rotates continuously counterclockwise, and the rotation of the fan 49 eventually causes the air nozzle 34 to continuously blow air outward.

[0044] The details of the continuous rotation of the air nozzle 34 are as follows: the disc gear 42 rotates to control the first support shaft 46, which then transmits the second cylinder gear 38 through the second support shaft 47 and the third gear 45, and then transmits the air nozzle 34 through the long shaft 36 and the short shaft 35.

[0045] The blowing details of the air nozzle 34 are as follows: the main air pipe 10 is externally connected to the cold air supply mechanism in the prior art, and the cold air is sucked into the air tube 50 through the main air pipe 10 and the flat tube 39, and then blown into the square cylinder 27 through the L-shaped air box 48, and then injected into the air nozzle 34 through the L-shaped air pipe 32. In this way, the air nozzle 34 blows out a cold air flow to the outside. However, due to the interception effect of the C-shaped air baffle 33, in the column 12 in the figure, a downward-swinging impact airflow is intermittently ejected from the air nozzle 34, and the airflow impacts the bottom curved surface of the head panel 14 and the plastic cloth, thereby avoiding the occurrence of adhesion problems.

[0046] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
