Description

Technical Field

[0001] This application relates to the field of tire manufacturing equipment technology, and more specifically, to a handheld electric pressure roller for a forming machine. Background Technology

[0002] In tire manufacturing, the sidewall and inner liner composite uses an overlapping joint. This overlapping joint is prone to several problems, such as abnormal rubber temperature, poor rubber adhesion, and tensile deformation. These issues can lead to quality defects in the finished tire, such as bulges or dents, during subsequent use. Therefore, to ensure product quality, a pressure roller device is used to press the rubber joint together, eliminating air bubbles and improving the flatness of the rubber, thereby enhancing tire quality.

[0003] In existing technologies, the pressing of film joints is mainly done manually using pressure rollers. This process requires repeated pressing operations, resulting in high labor intensity. Due to the nature of manual pressure roller operation, there are certain safety risks and operational errors, making it easy to miss parts of the film, leading to problems such as dead corners and uneven edges at the film joint. Furthermore, manual pressure roller operation inevitably introduces some operational errors; it is difficult to maintain a uniform speed when moving the roller, resulting in varying pressure on different parts of the film during pressing, and inconsistent pressing time. This non-standardized processing method leads to errors in the final product, inconsistent product quality, and impacts processing efficiency. Utility Model Content

[0004] To address the aforementioned problems, the present invention provides a handheld electric pressure roller for a tire forming machine, solving the issues of laborious use and poor pressing effect of manual pressure rollers in the tire forming process. It includes a pressure roller assembly, a drive assembly, and a handheld assembly connected in sequence. The pressure roller assembly includes a pressure roller shaft, a main shaft, and a pressure roller body mounted on the pressure roller shaft, with both ends of the pressure roller shaft connected to the main shaft. The drive assembly includes a drive motor, an eccentric wheel, and a transmission rod. The eccentric wheel is mounted on the output shaft of the drive motor, and one end of the transmission rod is connected to the outer circumference of the eccentric wheel, while the other end is detachably connected to the main shaft. The handheld assembly includes a mounting base and a grip handle. The front end of the mounting base is connected to the drive motor, and the other end is connected to the grip handle.

[0005] Preferably, the mounting base is provided with an auxiliary adjustment component that cooperates with the handheld component.

[0019] The present application will now describe a handheld electric pressure roller for a molding machine according to an embodiment of the present application.

[0020] Please see Figure 1 This is a schematic diagram of the structure of the present invention. The handheld electric pressure roller for the molding machine includes a pressure roller assembly, a drive assembly, and a handheld assembly connected in sequence. The pressure roller assembly includes a pressure roller shaft, a main shaft 2, and a pressure roller body 1 mounted on the pressure roller shaft. Both ends of the pressure roller shaft are connected to the main shaft 2. The drive assembly includes a drive motor, an eccentric wheel, and a transmission rod 3. The eccentric wheel is mounted on the output shaft of the drive motor. One end of the transmission rod 3 is connected to the outer circumference of the eccentric wheel, and the other end is detachably connected to the main shaft 2. The handheld assembly includes a mounting base 4 and a grip handle 8. The front end of the mounting base 4 is connected to the drive motor, and the other end is connected to the grip handle 8. Specifically, in use, the operator holds the grip handle 8, aligns the pressure roller body 1 with the film joint, and starts the drive motor. The output shaft of the drive motor begins to rotate, driving the eccentric wheel to rotate as well, which in turn drives the transmission rod 3 to move back and forth. Under the action of the transmission rod 3, the pressure roller assembly moves back and forth, repeatedly pressing the film.

[0021] Furthermore, the mounting base 4 is equipped with an auxiliary adjustment component that cooperates with the handheld component. The auxiliary adjustment component includes a fixing ring 6 sleeved on the front end of the mounting base 4 and an auxiliary handle 7 located at the bottom end of the fixing ring 6. The auxiliary handle 7 is rotatably connected to the bottom of the fixing ring 6. Specifically, during use, depending on usage habits and different compaction angles, the operator can adjust the grip posture through the auxiliary handle 7 to better exert force and reduce labor intensity.

[0022] Furthermore, the fixing ring 6 is detachably connected to the mounting base 4. By adjusting the position of the fixing ring 6, the position of the auxiliary adjustment component can be adjusted, thereby improving the applicability and auxiliary capability of the auxiliary handle 7.

[0023] Furthermore, the pressure roller body 1 is a hollow cylindrical structure, and the pressure roller body 1 is rotatably connected to the pressure roller shaft.

[0024] Furthermore, a spiral heating element is provided on the pressure roller shaft, and the heating element is coaxial with the pressure roller body 1. During use, the pressure roller body 1 is pressed against the film, and the heating element generates heat when energized. The heat is conducted through the air to make the pressure roller body 1 heat up evenly, thereby heating the film. Films with high hardness soften and are easier to press, expanding the range of applications and improving applicability. Specifically, when the pressure roller body 1 rotates, the heating element does not rotate with it, which ensures that the surface temperature of the pressure roller body 1 is consistent and the heating is uniform. It also facilitates the connection of an external power supply and the placement of a temperature sensor inside the pressure roller body 1 for temperature measurement.

[0025] In one embodiment, a temperature sensor for detecting the surface temperature of the pressure roller body 1 is provided inside the pressure roller body 1. The temperature sensor is electrically connected to a PLC controller, and the PLC controller is electrically connected to an electric heating element. Specifically, by measuring the temperature through the temperature sensor, the signal is transmitted to the PLC controller, which controls the electric heating element to adjust the temperature, thereby achieving accurate and high-precision temperature control to improve the pressing effect and pressing efficiency.

[0026] Furthermore, the bottom of the mounting base 4 is provided with a support platform 5 that extends vertically downwards. One end of the handle 8 is connected to the rear end of the mounting base 4, and the other end is connected to the side wall of the support platform 5.

[0027] Furthermore, the main shaft 2, transmission rod 3, and mounting base 4 are coaxially arranged, ensuring efficient and stable power transmission.

[0028] Furthermore, a protective cover 9 is provided on the outside of the drive motor along the axial direction to protect the drive motor and eccentric wheel, prevent impurities from entering the connection and reduce wear.

[0029] The working process of this utility model is as follows: During use, the operator holds the handle 8, aligns the pressure roller body 1 with the film joint, and starts the drive motor. The output shaft of the drive motor begins to rotate, driving the eccentric wheel to rotate as well, which in turn drives the transmission rod 3 to move back and forth. Under the action of the transmission rod 3, the pressure roller assembly moves back and forth, repeatedly pressing the film. Simultaneously, the heating element generates heat, which is conducted through the air to uniformly heat the pressure roller body 1, thereby heating the film. During this process, the temperature sensor measures the temperature in real time and transmits the signal to the PLC controller. The PLC controller controls the heating element to adjust the surface temperature of the pressure roller body 1.

[0030] In this invention, the drive motor drives the pressure roller body 1 to move back and forth through the eccentric wheel and transmission rod 3 to press the film joint. Repeated pressing can be completed without the need for manual force from the operator. The operator only needs to adjust the grip posture and the angle of the pressure roller body 1 through the auxiliary handle 7, which saves time and effort and reduces labor intensity. The driving force and reciprocating frequency of the drive motor are always consistent, which standardizes the pressing operation of the pressure roller body 1, achieves precise processing at the joint, minimizes processing errors, and results in high product quality and stability after pressing. The electric heating tube ensures a uniform surface temperature of the pressure roller body 1, and the film is heated evenly, which softens the harder film, making it easier to process, expanding the scope of application and improving applicability.

[0031] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
