Abstract
Description
Technical Field
[0001] The utility model relates to hot plate welding equipment, in particular to a Teflon cloth quick replacement mechanism used for the hot plate welding equipment. Background Art
[0002] A major problem with hot plate welding is that heated plastic overflows and accumulates on the heating plate. This overflow can severely impact the hot melt welding of new products, severely reducing weld quality. Sometimes, the plastic can even fall into the product, resulting in defective parts. This not only impacts product quality but also leads to labor waste and reduced production capacity. While the development of durable anti-stick coatings has significantly reduced the problem of hot plate welding, coated heating plates still require regular maintenance or replacement, and production requires a separate spare set for these needs. This increases production management costs and hinders mass production.
[0003] In order to meet the needs of mass production in welding manufacturing, Teflon cloth is now used instead of non-stick coating on hot plates. By adding Teflon cloth between the hot plate and the product, the problem of plastic welding sticking and high coating maintenance cost can be solved.
[0004] However, Teflon cloth is used less frequently and needs to be frequently replaced or repositioned. The current replacement method is manual replacement. Because the temperature of the hot plate in the process is too high, manual replacement is very dangerous. The equipment needs to be shut down and cooled to a suitable operating temperature for replacement, causing the production line to stop, work efficiency to decrease, speed to slow down, and production capacity to be affected, which directly affects the original intention of using Teflon to replace the anti-sticking layer. Utility Model Content
[0005] In response to the problems existing in the prior art, the utility model provides a Teflon cloth quick replacement mechanism for hot plate welding equipment, which solves the problem of product hot melt overflow adhering to the hot plate mold during hot plate welding of plastic products. Teflon cloth is used as an interlayer on the hot plate welding mold, and the Teflon cloth is replaced by an automated mechanism to improve replacement efficiency and product quality.
[0006] The technical solution of the utility model is: a Teflon cloth quick replacement mechanism for hot plate welding equipment, comprising a servo motor, a driving shaft, a driven shaft and two Teflon cloth guide fixed shafts;
[0007] The two Teflon cloth guide fixing shafts are placed in parallel, one on the left and one on the right, fixed to the left and right sides of the heating mold of the hot plate welding equipment, and can guide and control the Teflon cloth located between the two Teflon cloth guide fixing shafts to be flush with the heating mold;
[0008] The servo motor is connected to and controls the driving shaft, which is arranged on one side of the heating mold and is parallel to the Teflon cloth guide fixed shaft on the side;
[0009] The driven shaft is arranged on the other side of the heating mold and is parallel to the Teflon cloth guide fixed shaft on that side;
[0010] A predetermined roll of Teflon cloth is initially placed on the driven shaft.
[0011] Furthermore, the driven shaft is equipped with a tension damper.
[0012] Furthermore, the heating mold is fixed to the fixed bottom of the heating mold through a heating mold support plate.
[0013] Furthermore, the driving shaft and the Teflon cloth guided fixed shaft on one side of the heating mold are fixed by a driving shaft bracket fixed on the fixed bottom of the heating mold;
[0014] The driven shaft and the Teflon cloth guided fixed shaft on the other side of the heating mold are also fixed by a driven shaft bracket fixed on the fixed bottom of the heating mold.
[0015] Furthermore, each heating mold of the hot plate welding equipment is equipped with a set of Teflon cloth quick replacement mechanism.
[0016] The beneficial effects of the utility model are: providing a Teflon cloth quick replacement mechanism for hot plate welding equipment, using Teflon cloth to solve the problem of welding quality degradation caused by sticky materials in hot plate welding, and improving the qualified rate of product welding; utilizing the above-mentioned automatic control mechanical structure to solve the Teflon high-temperature cloth replacement process, avoiding personnel safety risks such as burns caused by manual replacement, improving safety performance, and saving labor costs and operation waiting time through automatic replacement control, thereby improving operation efficiency.

DETAILED DESCRIPTION
[0022] The present invention will be further described below with reference to the accompanying drawings.
[0023] like Figure 1-4 As shown, a Teflon cloth quick-changing mechanism for hot plate welding equipment includes a servo motor 11 , a driving shaft 13 , a driven shaft 9 and two Teflon cloth guide fixed shafts 12 .
[0024] The two Teflon cloth guide fixing shafts 12 are placed in parallel, one on the left and one on the right, fixed to the left and right sides of the heating mold 6 of the hot plate welding equipment, and can guide and control the Teflon cloth 15 located between the two Teflon cloth guide fixing shafts 12 to be flush with the heating mold 6.
[0025] The servo motor 11 is connected to and controls the driving shaft 13 . The driving shaft 13 is disposed on one side of the heating mold 6 and is parallel to the Teflon cloth guide fixed shaft 12 on the side.
[0026] The driven shaft 9 is arranged on the other side of the heating mold 6 and is parallel to the Teflon cloth guide fixed shaft 12 on this side. A tension damper 14 is also provided on the driven shaft 9.
[0027] The predetermined coil of Teflon cloth is initially placed on the driven shaft 9 .
[0028] The heating mold 6 is fixed to the heating mold fixed base 4 via a heating mold support plate 5. The driving shaft 13 and the Teflon cloth guide fixed shaft 12 on one side of the heating mold 6 are fixed by a driving shaft bracket 10 fixed to the heating mold fixed base 4. The driven shaft 9 and the Teflon cloth guide fixed shaft 12 on the other side of the heating mold 6 are also fixed by a driven shaft bracket 7 fixed to the heating mold fixed base 4.
[0029] Each heating mold 6 of the hot plate welding equipment is equipped with a set of Teflon cloth quick replacement mechanism.
[0030] During operation, the operator places the predetermined roll of Teflon cloth onto the driven shaft of the Teflon loading section. The cloth then passes through the guide positioning shaft to ensure it is flush with the heating plate. The starting section is then fixed to the driving shaft of the waste recovery section. The tension of the Teflon cloth is adjusted by the tension damper to ensure the flatness of the high-temperature cloth during operation. The control system automatically replaces the Teflon cloth. When the Teflon cloth has been used a specified number of times, the controller controls the servo motor to rotate and complete the replacement of the Teflon cloth.
