Description

Technical Field

[0001] This utility model relates to the field of winding mechanism technology, specifically a winding mechanism for a blown film machine. Background Technology

[0002] In the blown film production process, the winding mechanism of the blown film machine plays a crucial role. Traditional blown film machine winding mechanisms, such as those commonly consisting of a support, an active take-up roller, and a take-up roller, are responsible for winding and arranging the blown film in the film production process. The take-up support plate is fixed to the support, providing the necessary support structure for the winding process. For a specific structure, please refer to the winding device for a blown film machine disclosed in application number CN2023116452525.

[0003] However, such winding mechanisms have a significant drawback after the winding operation is complete. When the winding roller finishes winding the film and needs to be removed from the take-up support, it usually requires manual operation. Manually handling the wound winding roller not only consumes a lot of manpower but also requires operators to have a certain level of physical strength and skill. In large-scale production scenarios, frequent manual unloading severely impacts production efficiency, increases production costs, and becomes a bottleneck restricting the automation and efficiency of blown film production. Against this backdrop, developing a winding mechanism capable of automatic unloading has significant practical significance and application value. Utility Model Content

[0004] In view of the shortcomings in the prior art, this utility model provides a winding mechanism for a blown film machine.

[0005] The technical solution adopted by this utility model is: a winding mechanism for a blown film machine, including a support, an active winding roller and a winding roller, a winding support plate fixed on the support, and an auxiliary unloading mechanism, the auxiliary unloading mechanism including an unloading drive and unloading support plates arranged on both sides of the support.

[0006] The bottom of the unloading support plate is rotatably connected to the bracket, and the top of the unloading support plate has a receiving part, on which a "hook" shaped positioning groove is provided;

[0007] The unloading drive is used to drive the unloading support plate to rotate around the rotating shaft. Through the drive of the unloading drive, the unloading support plate can rotate from the receiving state to the discharging state.

[0008] Furthermore, the unloading drive is fixed on the bracket, and the output end of the unloading drive is rotatably connected to the pin fixed on the unloading support plate.

[0009] Furthermore, the unloading support plate is fixed together with the unloading support plate by a connecting beam.

[0010] Furthermore, the unloading support plate is provided with a weight reduction groove.

[0011] Furthermore, a take-up rack is fixed to the upper edge of the take-up support plate, and take-up shaft gears that mesh with the take-up rack are provided at both ends of the take-up roller.

[0012] Furthermore, the receiving rack has an arc-shaped structure.

[0013] Furthermore, the upper edge of the receiving support plate is an arc-shaped surface with the same curvature as the receiving rack.

[0014] Furthermore, the unloading drive component is a pneumatic cylinder, an electric cylinder, or a linear motor.

[0015] Furthermore, the bottom of the unloading support plate is rotatably connected to the bracket via a rotating shaft.

[0016] The beneficial effects of this utility model are:

[0017] First, it greatly saves labor costs. The previous method of manually handling the winding rollers has been replaced by automated unloading. Operators no longer need to spend a lot of physical strength on heavy unloading work, reducing reliance on manpower. Enterprises can allocate the saved manpower to other more valuable production processes, improving the overall efficiency of human resource utilization.

[0018] Secondly, it significantly improves production efficiency. The automatic unloading process is fast and continuous, avoiding the time wasted due to physical strength and operator skill during manual unloading. In large-scale production, each reduction in unloading time accumulates into a considerable production time gain, enabling the blown film machine to complete more winding tasks per unit time, accelerating the entire production process and increasing the company's capacity.

[0019] Furthermore, it effectively reduces production costs. The reduction in labor costs directly lowers the company's operating costs. At the same time, the efficient production process reduces equipment downtime, increases equipment utilization, and lowers overall production costs, such as equipment depreciation costs per unit of product, thereby enhancing the company's competitiveness in the market.

[0020] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0027] This utility model provides a winding mechanism for a blown film machine.

[0028] In this embodiment, refer to Figure 1-3 The film blowing machine's winding mechanism includes a support 1, an active take-up roller 2, and a winding roller 3. A take-up support plate 4 is fixed on the support. It also includes an auxiliary unloading mechanism, which includes an unloading drive 5 and unloading support plates 6 arranged on both sides of the support.

[0029] The bottom of the unloading support plate is rotatably connected to the bracket, and the top of the unloading support plate has a receiving part 8, on which a "hook" shaped positioning groove 9 is provided;

[0030] The unloading drive is used to drive the unloading support plate to rotate around the rotating shaft. Through the drive of the unloading drive, the unloading support plate can rotate from the receiving state to the discharging state.

[0031] After adopting the above technical solution, the unloading drive is activated after the blown film machine finishes winding, driving the unloading support plate to rotate around the shaft. Initially, the unloading support plate is in the receiving state (e.g., Figure 2 As shown in the diagram, the wound take-up roller falls into the "hook"-shaped positioning groove of the receiving section. When the unloading drive unit is activated, the unloading support plate rotates, rotating the unloading support plate and the take-up roller on the unloading support plate together to the ground, i.e., the discharge state (as shown in the diagram). Figure 3(As shown in the diagram). This enables automatic unloading of the take-up roller, solving the problem of time-consuming and labor-intensive traditional manual unloading, improving production efficiency, and reducing labor intensity.

[0032] Specifically, the unloading drive 5 is fixed on the bracket, and the output end of the unloading drive 5 is rotatably connected to the pin 10 fixed on the unloading support plate.

[0033] In this embodiment, the unloading drive is fixed to the bracket, and its output end is rotatably connected to a pin fixed to the unloading support plate. When the unloading drive performs a telescopic movement, the output end pushes the pin. Since the pin is fixed to the unloading support plate, it drives the unloading support plate to rotate around its bottom pivot. This connection method allows the linear motion of the unloading drive to be effectively converted into the rotational motion of the unloading support plate.

[0034] Specifically, the unloading support plate is fixed together with the unloading support plate by the connecting beam 11.

[0035] In this embodiment, the unloading support plate is fixed together with the unloading support plate by a connecting beam, so that the unloading support plates on both sides can move synchronously.

[0036] Specifically, the unloading support plate is provided with a weight reduction groove 12.

[0037] In this embodiment, the weight-reducing slots 12 provided on the unloading support plate reduce the overall weight of the unloading support plate without affecting its structural strength. When the unloading drive unit drives the unloading support plate to rotate, the lighter unloading support plate requires less driving force and moves more flexibly. At the same time, the presence of the weight-reducing slots also reduces the amount of material used.

[0038] Specifically, a take-up rack 13 is fixed on the upper edge of the take-up support plate, and take-up shaft gears 14 that mesh with the take-up rack are provided on both ends of the take-up roller.

[0039] In this embodiment, a take-up rack is fixed to the upper edge of the take-up support plate, and take-up shaft gears at both ends of the take-up roller mesh with the take-up rack. When the active take-up roller drives the take-up roller to perform the take-up operation, as the film being taken up by the take-up roller gradually increases in size, the take-up roller gradually rolls outward along the take-up rack via the take-up shaft gears, causing the take-up roller to move along the upper edge of the take-up support plate, thereby achieving uniform winding of the film on the take-up roller.

[0040] Specifically, the receiving rack has an arc-shaped structure.

[0041] In this embodiment, the take-up rack is designed with an arc-shaped structure to match the movement trajectory of the take-up roller during the take-up process.

[0042] Specifically, the upper edge of the receiving support plate is an arc-shaped surface 15 with the same curvature as the receiving rack.

[0043] In this embodiment, the upper edge of the receiving support plate is an arc-shaped surface with the same curvature as the receiving rack, and works together with the arc-shaped receiving rack.

[0044] Specifically, the unloading drive component is a pneumatic cylinder, an electric cylinder, or a linear motor.

[0045] Specifically, the bottom of the unloading support plate is rotatably connected to the bracket via a rotating shaft 7.

[0046] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
