Description

1 TARIFF MULTI-POINT BEARING SCISSOR UNIT Technical Area 5 The invention relates to the use of forming and gluing stations in thermoforming machines. It is related to the scissor unit. The invention specifically applies to forming and gluing stations in thermoforming machines. The movable block moves axially with smooth tolerances via bearings. station shears that enable the machine to produce and increase the speed of the thermoforming machine. It is related to the unit. State of the Art 15 Thermoforming machines are generally used in the packaging industry and are used to process plastic products. Thermoforming machines are machines that form products using heat. In thermoforming machines, heating, filling, cutting, and shaping are all performed. The packaging is shaped using shaping and gluing stations. Switch units are used for power transmission at the stations. The aforementioned 20 Shear units essentially open onto the lower surface of the upper mold on a movable block. The lower mold, once closed, is moved upwards by a pushing force to close onto the upper mold. It provides. In current technology, thermoforming machines have 25 forming and gluing stations. The scissor units used are pneumatically driven and have hinged joints that bend inwards towards each other. It consists of arms. The number of pneumatic equipment in these scissor units Due to its high volume, a high air consumption is required, and the station The failure rate is high. The shear operates with high energy consumption. Due to the bearings used in the joint structure of the system, lubrication and maintenance are 30. Although it is necessary, the unit is susceptible to external factors such as dust and water. This is due to the fact that the scissor arms bend inwards on opposite sides. due to the movement reaching the maximum distance, the counter load, i.e., the load carrying the molds, The movable block can impart downward acceleration to the scissor unit, which can lead to a loss of measurement. This causes problems. Also, the bearings in the articulated arms are 35 inches from the opposing arms. The force it applies causes a loss of measurement over time. 2 Therefore, faulty production results are encountered. However, pneumatic Since this driven system operates more slowly than a servo motor system, thermoforming It reduces the production capacity of the machine. It also increases energy consumption. There are too many. 5 In current technology, in thermoforming machines, at the shaping and gluing stations... In another servo-driven two-parallel arm system used, the parallel arms Mold collapse occurs due to deformation of the supporting bearings, and The desired print cannot be obtained on the foil. In this case, the measurements are taken during production. Adjustments are required, and this results in production stoppages. Same 10 Due to the need for periodic lubrication of bearings, labor and time are saved. There is a loss involved. In addition, the system in question has a 1.5kW servo. A motor is needed. This increases energy consumption. To ensure the elimination of the problems mentioned above, we have taken 15 steps. The station switch unit, which is the subject of application number TR2023 / 002176, has been improved. This unit is used for shaping and bonding in thermoforming machines. At the stations, the lower die is moved with low energy consumption via lever arms. This has been ensured. However, during the up-and-down movement of the movable block... Vibration occurs, and consequently, the lower mold closes onto the upper mold by exactly 20 seconds. Due to the lack of proper printing, the packaging produced experiences shifting from side to side. This... Therefore, a rigid structure is needed that allows the movable block to move within a smooth tolerance. A scissor unit was needed. In conclusion, the existence of the above problems and the inadequacy of the current solutions are relevant to the 25 This has made it necessary to make improvements in the technical field.
