Description

Technical Field

[0001] This utility model relates to the field of bubble stabilizer technology, specifically a horizontal adjustment mechanism for a bubble stabilizer. Background Technology

[0002] In the production of plastic film, blow molding is a widely used technology. In this process, the stable shape of the film bubble is crucial to the quality of the film, and the bubble stabilizer, as a key device for maintaining the stability of the film bubble, directly affects the forming effect of the film bubble through its horizontal adjustment mechanism. A typical example is the blown film bubble stabilizer for the production of environmentally friendly plastic bags disclosed in application number 2023110647799.

[0003] Currently, existing bubble stabilizing frame leveling mechanisms typically include multiple adjustment components, each requiring an independent rotary drive to achieve its opening and closing adjustment function. This structural design has several drawbacks: firstly, the use of multiple rotary drives makes the entire leveling mechanism more complex, increasing the number of parts, which not only increases the manufacturing cost of the equipment but also raises the assembly difficulty and subsequent maintenance workload; secondly, because the operating parameters of each rotary drive are difficult to keep completely consistent, when adjusting multiple adjustment components synchronously, problems such as low adjustment accuracy and poor consistency can easily occur, which in turn affects the morphological stability of the bubble and is detrimental to ensuring the production quality of plastic film.

[0004] Therefore, developing a bubble holder leveling mechanism that can simplify the structure, reduce costs, and improve adjustment consistency has become an urgent problem for those skilled in the art. Utility Model Content

[0009] The first hinge plate and the second hinge plate are arranged at the middle of each other and are rotatably connected by a pin.

[0010] The linkage gear is fixedly connected to the upper end of the screw, and the linkage gear ring meshes with the drive gear and the linkage gear for transmission.

Detailed Implementation

[0023] 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.

[0024] 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.

[0025] This utility model provides a horizontal adjustment mechanism for a bubble stabilizer.

[0026] In this embodiment, refer to Figure 1-3The horizontal adjustment mechanism of the bubble stabilizer includes an annular support 100 and horizontal adjustment components 200 spaced apart on the annular support. A membrane bubble channel is formed within the horizontal adjustment component 200 through which the membrane bubble 300 passes. The horizontal adjustment component includes a rotary drive 201 fixed on the annular support, a drive gear 202, a linkage gear ring 203, and multiple adjustment mechanisms 204. The output end of the rotary drive 201 is connected to the drive gear 202. The linkage gear ring 203 is driven and connected to the drive gear and the linkage gear 218 of the adjustment mechanism, and is used to synchronously drive multiple adjustment mechanisms to perform synchronous opening and closing adjustment.

[0027] In the above technical solution, the horizontal adjustment mechanism of the bubble stabilizer includes a ring support and multiple horizontal adjustment components. Each horizontal adjustment component includes a rotary drive, a drive gear, a linkage gear ring, and multiple adjustment mechanisms. The rotary drive drives the drive gear to rotate, and the linkage gear ring is driven to connect with the drive gear and the linkage gear of the adjustment mechanism. Thus, by means of this transmission relationship, only one rotary drive can synchronously drive multiple adjustment mechanisms to perform synchronous opening and closing adjustment.

[0028] Compared to existing structures where each adjustment component requires an independent drive, this design simplifies the overall structure, reduces the number of parts, and lowers manufacturing and maintenance costs. Simultaneously, it avoids inconsistencies in adjustment caused by parameter differences among multiple drive components, improves the consistency of action across multiple adjustment mechanisms, thereby ensuring stable membrane bubble morphology and enhancing thin film production quality.

[0029] Specifically, the adjustment mechanism includes a screw 205, a bearing seat 206, an upper support plate 207, a lower support plate 208, a connecting plate 217, a first hinge plate 209, a second hinge plate 210, a bubble stabilizing plate 211, and a bubble stabilizing assembly. One end of the upper support plate 207 is fixed to the upper end of the annular bracket, and the other end is rotatably connected to the upper end of the second hinge plate 210. One end of the connecting plate 217 is fixed to the bubble stabilizing plate, and the other end is rotatably connected to the first hinge plate. One end of the lower support plate 208 is rotatably connected to the lower end of the first hinge plate, and the other end is provided with a screw hole 212. The bearing seats are respectively fixed on the upper and lower sides of the annular bracket. Both ends of the screw are rotatably connected to the bearing seats, and the screw is screwed to the screw hole.

[0030] The lower end of the second hinge plate slides in conjunction with the lower end of the bubble stabilizing plate via a slide rail slider;

[0031] The first hinge plate and the second hinge plate are arranged at the middle of the cross and are rotatably connected by the pin 214;

[0032] The linkage gear is fixedly connected to the upper end of the screw, and the linkage gear ring meshes with the drive gear and the linkage gear for transmission.

[0033] In this embodiment, the rotation of the screw drives the lower support plate to move. Through the cross-hinged structure of the first and second hinge plates, the bubble stabilizing plate can be adjusted in opening and closing. At the same time, the linkage gear is fixed to the upper end of the screw, and the linkage gear ring drives the linkage gear to rotate. This makes the opening and closing adjustment of the adjustment mechanism more precise and stable, and can flexibly adjust the size of the bubble channel to meet the needs of different sized bubbles, further improving the constraint effect of the bubble stabilizing frame on the bubble.

[0034] Specifically, the bubble stabilizing assembly includes an "U"-shaped frame 215 fixed on the bubble stabilizing plate and a roller 216 rotatably connected within the "U"-shaped frame 215.

[0035] In this embodiment, the U-shaped frame of the bubble stabilizing unit is fixed to the bubble stabilizing plate, and the roller shaft is rotatably connected inside the U-shaped frame. When the film bubble passes through, it contacts the roller shaft, which can rotate with the movement of the film bubble. The rotation of the roller shaft reduces friction between the roller shaft and the film bubble, avoiding damage to the surface of the film bubble and ensuring the integrity and surface quality of the film. The U-shaped frame provides stable support for the roller shaft, ensuring the structural stability of the bubble stabilizing unit during operation.

[0036] Specifically, a position sensor 219 for detecting the position of the lower support plate is fixed on the annular bracket on the side of one of the horizontal adjustment components.

[0037] In this embodiment, the position sensor can monitor the position of the lower support plate in real time, providing feedback signals for the control of the adjustment mechanism, which facilitates automated and precise adjustment, avoids over- or under-adjustment, and improves the intelligence and adjustment accuracy of the entire horizontal adjustment mechanism.

[0038] Specifically, the annular support includes an upper ring 220, a lower ring 221, and a connecting post 222 for connecting the upper ring and the lower ring.

[0039] In this embodiment, the ring bracket consists of an upper ring, a lower ring, and a connecting column, which connects the upper ring and the lower ring into a whole.

[0040] Specifically, there are multiple bubble stabilizing groups, which are arranged at equal intervals along the length of the bubble stabilizing plate.

[0041] In this embodiment, multiple bubble stabilizing groups are arranged at equal intervals along the length of the bubble stabilizing plate, working together to support the bubble. This increases the contact points with the bubble, making the supporting force on the bubble more uniform and further enhancing the stabilizing effect on the bubble's shape. It is suitable for bubble of different sizes, improving the applicability of the bubble stabilizing frame.

[0042] 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.
