Description

Technical Field

[0001] This utility model relates to an improved invention of a blown film machine, and more particularly to an improved invention of a blown film machine pulley fixing seat. Background Technology

[0002] In the operation of a blown film machine, the transmission system is a crucial component for ensuring the machine's normal functioning. In traditional blown film machines, pulleys are typically mounted on the main shaft, and power is transmitted via belt drive. However, existing technology has several significant drawbacks, primarily in the following aspects: Structural defects due to single-sided fixing: Most existing blown film machines use a single-end fixed shaft design, meaning the main shaft is supported only at one end by a bearing or mounting base. This structure is prone to shaft misalignment or tilting when the pulley is under load, leading to unstable transmission and even jamming; Poor transmission stability: Because single-sided fixing cannot effectively distribute the torque generated during transmission, the pulley is prone to vibration and eccentricity at high speeds, affecting transmission efficiency and equipment lifespan. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a belt pulley fixing seat for a blown film machine.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the blown film machine pulley fixing seat includes a base plate, characterized in that: the base plate is provided with two side plates distributed on the left and right, the two side plates and the base plate form a U-shaped structure, a main shaft runs through the two side plates, a pulley assembly is provided on the main shaft, the corresponding two side plates are provided with mounting grooves for the main shaft to radially pass through, bearings are sleeved at both ends of the main shaft, the bearings are equipped with connecting plates integrally formed therewith, the connecting plates are assembled and connected with the corresponding side plates, and the base plate or side plates are provided with mounting holes for connection and cooperation with the blown film machine frame.

[0005] The pulley assembly includes two or more pulleys that are engaged in transmission.

[0006] The pulley assembly is located in the middle of the main shaft or at both ends of the main shaft.

[0007] The groove of the mounting slot is located on the upper edge of the side plate away from the bottom plate or on the side edge of the side plate.

[0008] An extension section is provided at the end of any side panel away from the base plate, and the mounting hole is provided on the extension section.

[0009] The beneficial effects of this utility model are as follows: The improved blown film machine pulley fixing seat has significantly enhanced structural stability. The U-shaped structure design, formed by setting left and right side plates on the base plate, provides double-sided support for the main shaft, avoiding the eccentricity problem of traditional single-sided fixing. Bearing and connecting plate cooperation: Bearings are fitted at both ends of the main shaft and connected to the side plates via connecting plates, effectively distributing the force, improving the overall structural stability and deformation resistance, and facilitating installation and maintenance. Radial insertion mounting groove: The side plates have mounting grooves for the main shaft to radially insert, simplifying the main shaft assembly process and improving installation efficiency.

A main shaft 3 passes through the two side plates 2, and a pulley assembly 4 is provided on the main shaft 3. The corresponding two side plates 2 are provided with mounting grooves 5 for the main shaft 3 to pass through radially. The radially inserted mounting grooves 5 facilitate the assembly of the pulleys onto the side plates 2 along with the main shaft 3. Bearings 6 are sleeved at both ends of the main shaft 3. The bearings 6 are equipped with connecting plates 7. The connecting plates 7 and the bearings 6 are integrally set. The connecting plates 7 are assembled and connected to the corresponding side plates 2. The connected connecting plates 7 and the side plates 2 are provided with corresponding connecting holes 8 and are detachably connected by fasteners. The base plate 1 or the side plates 2 are provided with mounting holes 9 that connect and cooperate with the blown film machine frame. The fixing seat can be fixed to the horizontal platform surface of the blown film machine frame through the base plate 1, or fixed to the vertical platform surface of the blown film machine frame through the side plates 2.
