Description

Technical Field

[0001] This utility model relates to the field of film cooling line technology, and in particular to an anti-sticking device suitable for film cooling lines. Background Technology

[0002] In the mixing process of tire manufacturing, rubber sheets need to undergo key processes such as water cooling and shaping, conveying and pressing, and forced air cooling to meet the process requirements of subsequent processing and storage. Specifically, after being cooled by water cooling, the mixed rubber sheets are conveyed by a lifting belt along a preset track to the cooling platform inlet. At this point, the rubber sheets are precisely pressed onto the surface of the hanging rod by a multi-layer sheet pressure roller. The rubber sheets then enter the cooling station along with the hanging rod. However, existing rubber sheet cooling lines suffer from multiple technical bottlenecks in their anti-jamming and pressing structures, severely restricting the continuous operation and production of the production line. Regarding product quality stability, specific issues are as follows: First, jamming in the transmission structure leads to pressing failure. The existing plywood pressing roller uses a linear reciprocating floating structure guided by an elongated hole. This structure relies on the hard contact between the elongated hole and the guide shaft for motion guidance. When the production line frequently switches between thin and thick sheets, and between low and high hardness rubber materials, the inner wall of the guide hole is prone to burrs due to wear, or the transmission resistance may increase sharply due to grease loss from heat, leading to mechanical transmission jamming. This jamming phenomenon causes a lag in the lamination action of the plywood pressing roller, or... The movement trajectory deviates from the preset path, ultimately causing the pressing position of the film and the adhesive rod to shift. Secondly, the dimensional defects of the multi-layer film cause the adhesive to slip, and the eccentric pressure causes pressure energy loss. Existing multi-layer films have the dual defects of insufficient single-layer thickness and poor axial dimension matching, which makes the interlayer fit tolerance of the adhesive pins on the surface of the multi-layer film and the adhesive rod prone to interlayer misalignment. This causes the adhesive pins to fail to effectively penetrate the film, causing the adhesive to slip along the axial direction of the adhesive rod or even fall off. In the traditional structure, the installation axis of the multi-layer film pressure roller and the geometric center of the adhesive rod are... The center has an angle of 8 to 12°, forming an eccentric compression state. When the pressure roller applies a pressing force of 5 to 8 MPa to the film, about 15% to 20% of the pressure energy will be converted into additional torque, resulting in the effective pressure acting on the bonding surface between the film and the adhesive rod being less than 4 MPa. Especially when processing high-hardness films with a Shore hardness of 65 to 75 HA, the effective pressure cannot break through the elastic deformation threshold of the film, resulting in insufficient bonding between the film and the adhesive rod, which easily leads to false pressure. During the subsequent air cooling process, the film is prone to wrinkles due to poor bonding. Utility Model Content

[0003] The purpose of this invention is to provide an anti-stick jamming device suitable for film cooling lines, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an anti-glue jamming device suitable for film cooling lines, including a cooling unit frame, a device support column connected to the bottom of the cooling unit frame, a glue-hanging mechanism inside the cooling unit frame, a glue-pressing multi-layer roller on one side of the glue-hanging mechanism, multi-layer sheets on the outer surface of the glue-pressing multi-layer roller, a swing bracket, a connecting rod and a crank connected to the outer side of the glue-pressing multi-layer roller, and a film conveyor belt on one side of the cooling unit frame.

[0005] As a further technical solution of this utility model, an air-cooled fan module is provided inside the cooling unit frame. The air-cooled fan module is positioned corresponding to the glue-applying mechanism, and the equipment support columns are distributed and welded to the four bottom corners of the cooling unit frame.

[0006] As a further technical solution of this utility model, the glue-coating mechanism includes a glue-coating frame, a series shaft, glue-coating rods, an upper guide wheel, and a lower guide wheel. The glue-coating frame is fixed inside the cooling unit frame. A series shaft is installed through the glue-coating frame. Multiple glue-coating rods are provided, and the multiple glue-coating rods are evenly spaced and sleeved on the series shaft. An upper guide wheel is provided at the top of the glue-coating frame, and a lower guide wheel is provided at the bottom of the glue-coating frame. A pressure roller is correspondingly provided on the glue-coating rod.

[0007] As a further technical solution of this utility model, the two ends of the pressure roller are rotatably connected to the swing bracket, and the layers are evenly distributed along the pressure roller.

[0008] As a further technical solution of this utility model, an upper belt traction roller and a lower belt traction roller are respectively provided on the upper and lower sides of the film conveyor belt, and belt drive gears are meshed and connected inside the upper belt traction roller and the lower belt traction roller.

[0009] As a further technical solution of this utility model, a belt tensioning roller is provided on the outer side of the film conveyor belt, and tensioning arms are connected to both ends of the belt tensioning roller.

[0010] As a further technical solution of this utility model, one end of the tensioning arm is hinged to a lower adjusting cylinder, and the other end of the tensioning arm is hinged to an upper adjusting cylinder.

[0011] As a further technical solution of this utility model, one end of the connecting rod is hinged with a crank, and the other end of the connecting rod is hinged with a swing bracket.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This utility model adopts a structured design. The device uses a swing bracket and crank-connecting rod structure to replace the traditional elongated hole guide structure. The swing bracket converts the rotational motion of the power source into the arc swing trajectory of the multilayer sheet shaft through the crank-connecting rod. There is no hard contact guide friction throughout the process. No transmission jamming can be avoided when switching the rubber material specifications on the production line. The response time of the lamination action is greatly shortened, ensuring the accurate pressing position of the film and the glue-hanging rod, significantly improving the pressing success rate. Furthermore, based on the experimentally determined precise size of the multilayer sheet, it is completely matched with the effective length of the glue-hanging rod, completely eliminating the interlayer fit tolerance with the glue-hanging nail. After the multilayer multilayer sheets are fixed by the series shaft, the interlayer fit is tight with no axial allowance, which can ensure that the glue-hanging nail completely penetrates the film. This device effectively prevents rubber slippage and detachment, significantly reducing downtime caused by rubber detachment and ensuring continuous production line operation. Its concentric positioning and pressing structure, through precision machining, ensures the coaxiality of the installation axis of the multi-layer sheet pressure roller with the geometric center of the adhesive rod, making the point of action of the multi-layer sheet completely coincide with the center of mass of the adhesive rod. This completely eliminates the additional torque generated by eccentric pressure, ensuring effective pressing force on the bonding surface even when handling high-hardness rubber sheets. This significantly improves the adhesion between the rubber sheet and the adhesive rod, preventing rubber wrinkling during subsequent air cooling and ensuring product quality stability. The innovative synergistic effect significantly reduces the frequency and duration of unplanned downtime in the rubber sheet cooling line, significantly improving the production efficiency of the mixing process. Simultaneously, it drastically reduces the rate of defective rubber products, minimizing raw material waste. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Please see the appendix Figure 1 -Appendix Figure 5This utility model provides an embodiment of an anti-glue jamming device suitable for film cooling lines, comprising a cooling unit frame 1, with equipment support columns 3 connected to the bottom of the cooling unit frame 1, a glue-applying mechanism 5 disposed within the cooling unit frame 1, a pressure roller 6 disposed on one side of the glue-applying mechanism 5, a layered sheet 17 disposed on the outer surface of the pressure roller 6, and a swing bracket 4, a connecting rod 11, and a crank 12 connected to the outer side of the pressure roller 6; a film conveyor belt 7 disposed on one side of the cooling unit frame 1; an air-cooled fan module 2 disposed within the cooling unit frame 1, the air-cooled fan module 2 being positioned corresponding to the glue-applying mechanism 5; and equipment support columns 3 being distributed and welded to the four bottom corners of the cooling unit frame 1. The cooling unit frame 1 is the device. The system provides a rigid load-bearing foundation. The equipment support column 3 is welded to provide stable support for the cooling unit frame 1, preventing deformation of the frame due to its own weight and the load of internal components. The air-cooled fan module 2 is set corresponding to the glue-coating mechanism 5, which can implement directional forced convection heat transfer on the glue sheet after it is pressed on the glue-coating mechanism 5, ensuring that the temperature of the glue sheet is accurately reduced to the range required by subsequent processing and storage processes. The glue-coating mechanism 5 includes a glue-coating frame 501, a series shaft 502, glue-coating rods 503, an upper guide wheel 504, and a lower guide wheel 505. The glue-coating frame 501 is fixed inside the cooling unit frame 1. The series shaft 502 is installed through the glue-coating frame 501. There are multiple glue-coating rods 503, which are evenly spaced and sleeved on the series shaft 502. On the coupling 502, an upper guide wheel 504 is provided at the top of the glue-coating frame 501, and a lower guide wheel 505 is provided at the bottom of the glue-coating frame 501. A pressure roller 6 is correspondingly provided on the glue-coating rod 503. The glue-coating frame 501 is the core mounting base of the glue-coating mechanism 5. The connection with the cooling unit frame 1 ensures the stability of the glue-coating structure position. The coupling shaft 502 plays a role in positioning and connecting multiple glue-coating rods 503. The glue-coating rods 503, which are evenly spaced, can achieve uniform suspension of the glue sheets. The two ends of the pressure roller 6 are rotatably connected to the swing bracket 4. Thousand-layer sheets 17 are evenly distributed along the pressure roller 6. The pressure roller 6 is rotatably connected to the swing bracket 4 at both ends, and can perform arc swing synchronously with the swing bracket 4. The rotating motion avoids the transmission jamming of traditional linear reciprocating structures; the upper and lower sides of the film conveyor belt 7 are respectively provided with an upper belt traction roller 8 and a lower belt traction roller 10. Both the upper belt traction roller 8 and the lower belt traction roller 10 are meshed with belt drive gears 9. The upper belt traction roller 8 and the lower belt traction roller 10 provide driving force from the upper and lower sides of the film conveyor belt 7 respectively. The meshing connection of the belt drive gears 9 achieves complete synchronization of their rotation speeds; a belt tension roller 13 is provided on the outer side of the film conveyor belt 7. Tensioning arms 15 are connected to both ends of the belt tension roller 13. The belt tension roller 13 is in contact with the outer surface of the film conveyor belt 7. The tensioning arms 15 provide swingable mounting support for the belt tension roller 13.One end of the tensioning arm 15 is hinged to a lower adjusting cylinder 14, and the other end is hinged to an upper adjusting cylinder 16. The lower adjusting cylinder 14 and the upper adjusting cylinder 16 provide driving force to the tensioning arm 15 through the hinge structure, and can extend and retract in real time according to the load change or thermal deformation of the film conveyor belt 7. One end of the connecting rod 11 is hinged to a crank 12, and the other end is hinged to a swing bracket 4. The crank 12, the connecting rod 11, and the swing bracket 4 together constitute a swing transmission mechanism. After receiving the rotational power from the external power source, the crank 12 converts the rotational motion into the arc swing motion of the swing bracket 4 through the connecting rod 11.

[0022] Working Principle: Using this invention, the water-cooled and shaped film first enters the conveying stage. This stage uses the film conveyor belt 7 as the core carrier, in conjunction with the upper belt traction roller 8, the lower belt traction roller 10, the belt drive gear 9, and the tension adjustment component to achieve precise conveying without slippage or wrinkles. The power system is connected through the lower belt traction roller 10, and forms a meshing transmission with the upper belt traction roller 8 through the belt drive gear 9, ensuring that the speeds of the upper and lower traction rollers are completely synchronized, avoiding film deviation due to transmission speed difference. The synchronously rotating traction rollers drive the film conveyor belt 7 to run along the preset trajectory, smoothly conveying the film to the cooling platform inlet, providing a stable initial positioning for the subsequent pressing process. This addresses the issue of traditional conveyor belts being prone to deformation due to load changes or heat. To address the issues of slippage due to slack and wear due to excessive tightness, this device incorporates a dynamic tension adjustment mechanism. A belt tensioning roller 13, located on the outer side of the film conveyor belt 7, is connected to tensioning arms 15 at both ends. One end of the tensioning arm 15 is hinged to a lower adjusting cylinder 14, and the other end is hinged to an upper adjusting cylinder 16. When belt tension deviates, the cylinder can extend and retract in real time, driving the tensioning arm 15 to swing, which in turn causes the belt tensioning roller 13 to compress the belt and compensate for the tension, ensuring the belt is always in optimal tension. This effectively avoids subsequent pressing failures caused by conveyor deviation. When the film reaches the cooling platform inlet, the core transmission system of the device—the combination of the swing bracket 4, connecting rod 11, and crank 12—immediately activates, achieving efficient power conversion and smooth transmission. An external power source drives the crank 12 to rotate around a fixed axis. The crank 12 drives the connecting rod 11 to perform reciprocating push-pull motion through a hinge structure. The other end of the connecting rod 11 is hinged to the swing bracket 4, ultimately converting the rotational motion of the crank 12 into the arc-shaped swing motion of the swing bracket 4. The two ends of the pressure roller 6 are rotatably connected to the swing bracket 4, and synchronously execute the arc-shaped pressing trajectory with the swing bracket 4. This transmission design completely abandons the linear reciprocating structure of the long oval hole guide of the traditional device. The traditional structure relies on the hard contact between the long oval hole and the guide shaft to achieve motion constraint. When frequently switching working modes, the transmission is prone to jamming due to wear of the guide hole and loss of grease, resulting in delayed lamination action response or inaccurate trajectory. However, the swing transmission of this device has no hard contact friction throughout the entire process. Even under the condition of high-frequency switching of rubber material specifications, it can still ensure the movement of the pressure roller 6. Compared to traditional structures, this device features a shorter response time, eliminating the risk of pressing failure caused by transmission jamming. Simultaneously with the start of the swing transmission system, the glue-coating mechanism 5 precisely aligns the film with the glue-coating rod 503, providing a pre-positioning guarantee for subsequent pressing operations. The glue-coating mechanism 5 consists of a glue-coating frame 501, a connecting shaft 502, glue-coating rods 503, an upper guide wheel 504, and a lower guide wheel 505. The glue-coating frame 501 is fixed inside the cooling unit frame 1, providing rigid support for the overall glue-coating structure. The connecting shaft 502 extends laterally through the glue-coating frame 501, and multiple glue-coating rods 503 are evenly fitted onto the connecting shaft 502 at preset intervals, forming a parallel glue-coating array. This ensures that the film can be evenly distributed and suspended. Precise pressing is the core element of this device in achieving anti-jamming and anti-slip properties.Relying on the pressure roller 6, the layered sheet 17, and the concentric positioning design, a gapless bonding between the film and the adhesive rod 503 is achieved. The layered sheet 17 is evenly distributed axially on the outer surface of the pressure roller 6. The single-piece size of the layered sheet 17 has been optimized through experiments, completely eliminating the defects of traditional layered sheets 17, such as insufficient thickness and excessive axial allowance. Due to thickness deviation and axial gap, traditional layered sheets 17 have interlayer fit tolerances with the adhesive rod 503 surface adhesive nails, which easily leads to the adhesive nails not being able to effectively penetrate the film. However, the dimensions of the layered sheet 17 in this device are perfectly aligned with the adhesive rod surface adhesive... The nails are perfectly matched, with no tolerance between layers, precisely guiding the adhesive nails to penetrate the film, preventing adhesive slippage and detachment from the source. After pressing, the film, along with the adhesive rod 503, enters the cooling unit frame 1 fixed to the equipment support column 3, initiating the directional cooling process. The pre-installed air-cooled fan module 2 within the cooling unit frame 1 is positioned corresponding to the adhesive application mechanism 5, enabling directional forced convection heat exchange on the film. Furthermore, due to the tight fit between the film and the adhesive rod 503, there are no localized uneven cooling issues during the cooling process, significantly improving the flatness of the film.
