Description

Technical Field

[0001] The invention relates to the technical field of plastic bag processing, in particular to a heat-sealing cloth installation mechanism for heat-sealing processing. Background Art

[0002] In the process of processing plastic bags, it is usually necessary to heat seal them at a fixed point to facilitate the forming of the bags. In order to prevent the plastic bags from directly contacting the heat sealing knife and causing hot melting, heat sealing cloth is usually laid in the middle. With its good thermal conductivity, the heat sealing effect can be improved. At the same time, the use of heat sealing cloth will be damaged by temperature and friction, and needs to be replaced regularly. Installation and replacement through heat sealing cloth installation mechanism is an existing conventional means, but the existing heat sealing cloth installation mechanism has the following problems when used: The existing heat-sealing cloth installation mechanism is mostly used to directly roll up the heat-sealing cloth when replacing it, which is not convenient for smoothly replacing the heat-sealing cloth. When rolling up, the heat-sealing cloth directly rubs against the bottom of the heat-sealing knife. Under the influence of friction and heat from the heat-sealing knife, the new heat-sealing cloth is worn out before it is used, which seriously affects its service life. At the same time, when heat-sealing plastic bags of different specifications, the width of the heat-sealing knife head is also different. The existing heat-sealing cloth installation mechanism is not convenient to adjust the winding length according to the change of the heat-sealing knife, resulting in the unused heat-sealing cloth being rolled up, causing material waste and shortening the overall maintenance time.

[0003] In view of the above problems, it is urgent to carry out innovative design based on the original heat sealing cloth installation mechanism. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, when the heat-sealing cloth is rolled up, the hydraulic rod drives the heat-sealing knife to move upward, so that it is separated from the bottom heat-sealing cloth, so as to avoid the friction between the heat-sealing cloth and the heat-sealing knife in this area during rolling up, which affects the quality and use. At the same time, the upward movement of the heat-sealing knife will drive the winding frame to move downward, so that the bottom falling area of ​​the heat-sealing cloth becomes gentle, which is helpful for subsequent rolling up and avoids the inconsistency of winding and unwinding on both sides. Furthermore, the downward movement of the winding frame synchronously winds up the heat-sealing cloth through the winding mechanism, and confirms the winding end time through the on-off switching of the electromagnet and the induction of the rack position by the pressure sensor, which can greatly reduce the unnecessary factors of damage to the heat-sealing cloth and improve the service life; 2. When the present invention is applied to hot air knives of different thicknesses, on the one hand, the angle of the winding frame can be adjusted by rotating the mounting plate, and on the other hand, the height of the winding frame can be adjusted synchronously, that is, the guide roller and the bottom of the heat-sealing knife can have a corresponding angle and distance, thereby ensuring the wrapping of the heat-sealing cloth and the heat-sealing knife, improving the heat-sealing effect, and avoiding the heat-sealing area being too large or too small. At the same time, the initial position of the push column can be adjusted, so that when the winding frame is driven to move downward by the contact between the push head and the push column during winding, the change of the initial position of the push column can adjust the moving down time of the winding frame, and then the winding length of the heat-sealing cloth can be adjusted in cooperation with the winding mechanism, so that when a thinner heat-sealing knife is used, the length of the heat-sealing cloth wound each time is also less, thereby avoiding the waste of the heat-sealing cloth, improving the use efficiency, and reducing the maintenance time.

[0020] Working principle: When the heat-sealing cloth installation mechanism for heat-sealing processing is used, first, the hydraulic rod 2 is used to regularly drive the connecting piece 3 and the heat-sealing knife 4 to move upward, so that the bottom of the heat-sealing knife 4 is separated from the heat-sealing cloth. At this time, the connecting piece 3 drives the first piston rod 132 to move upward in the first oil tank 131, squeezes the oil into the second oil tank 133, drives the second piston rod 134 to move horizontally, and the inclined surface of the second piston rod 134 contacts the push head 135, and the installation frame 7 is pushed downward by the push head 135, and then the winding frame 9 is pushed downward by the installation bar 8, so that the lowermost falling area of ​​the heat-sealing cloth becomes gentle. At this time, the electromagnet 15 in the telescopic sleeve 151 is controlled. 6 fixes the rack 154, so that when the winding frame 9 moves down, the rack 154 can drive the gear roller 11 to rotate through the gear 157, and then the winding roller 12 on the gear roller 11 rotates to wind the heat sealing cloth, and the heat sealing cloth in contact with the heat sealing knife 4 at the bottom is replaced with a new one. Then, when the heat sealing knife 4 and the winding frame 9 are reset, the electromagnet 156 is powered off and no longer fixes the rack 154. The rack 154 can move up with the friction strip 158 and the gear 157. After multiple operations, the rack 154 gradually moves up in the telescopic sleeve 151 until it contacts the pressure sensor 155, and the background issues an alarm to prompt the replacement of a new heat sealing cloth; When heat sealing different bags, the thickness of the blade head of the heat sealing knife 4 needs to be replaced. At this time, when replacing a thinner heat sealing knife 4, the mounting plate 6 can be rotated inward to adjust the angle of the winding frame 9. At the same time, the mounting bar 8 is driven to move downward in the mounting frame 7 through the contact guidance of the adjusting column 141 and the adjusting plate 142, and the height of the winding frame 9 is adjusted, so that when a thinner heat sealing knife 4 is used, the angle between the two guide rollers 121 and the bottom of the heat sealing knife 4 is smaller to avoid the heat sealing area from becoming larger. At the same time, the downward movement of the mounting frame 7 drives the push column 136 to move downward, so that when the heat sealing cloth is rolled up, the push head 135 pushes the mounting frame 7 to move downward with a certain hysteresis, thereby reducing the winding length of the heat sealing cloth and improving the utilization efficiency of the heat sealing cloth.
