TECHNICAL FIELD
[0001] The present application relates to the technical field of winding packaging machines, in particular to a winding packaging machine core mechanism with automatic sensing function. BACKGROUND
[0002] The winding packaging machine is an automatic packaging device, and its working principle is that the object to be wound is placed in the center of the rotating disc, the rotating disc motor is started to rotate, the rotating disc is naturally driven to rotate, the winding film is gradually wound on the object to be wound, and at the same time, the elevator motor is also started, the winding machine drives the entire core of the winding bundling machine to move up and down, so as to achieve the winding in the height direction of the object, thereby realizing the winding packaging of the entire outer surface of the object.
[0003] In the winding process, the main thing is to adjust the tension of the winding film. When the existing winding packaging machine winds and packages the object to be wound, the tightness of the winding film is not guaranteed, and the quality of the package cannot be guaranteed if the winding is too loose. If the winding is too tight, the stretching of the winding film is excessive, which may not only damage the winding film, but also may damage the object to be wound. Therefore, the tightness of the winding film needs to be adjusted to ensure the normal tension of the winding film and the quality of the winding. CONTENT OF THE INVENTION
[0004] In order to solve the above problems, realize the adjustment of the winding tension of the winding film, and ensure the quality of the winding packaging, the present application provides a winding packaging machine core mechanism with automatic sensing function.
[0005] The winding packaging machine core mechanism with automatic sensing function provided by the present application adopts the following technical scheme.
[0006] A winding packaging machine core mechanism with automatic sensing function, comprising a frame body, a first rubber roller, a second rubber roller and a guide roller are sequentially and spacedly arranged on the frame body along the winding film direction.
[0007] The first rubber roller and the second rubber roller are driven to rotate by a power element arranged on the frame body, and the linear speed ratio of the first rubber roller to the second rubber roller is less than 1.
[0008] A detection roller for tensioning the winding film is arranged between the guide roller and the second rubber roller, a spring is connected between the detection roller and the frame body in the direction of approaching or moving away from the winding film, and a detection switch for detecting the position of the detection roller is arranged on the frame body.
[0009] By adopting the above technical solution, the arrangement of the first rubber roller, the second rubber roller, and the guide roller can support, guide, and transport the stretch film. During stretch packaging, as the object being wrapped tightens the stretch film, the film gradually tightens, causing the detection roller to move against the spring force. When the detection switch detects the detection roller, a detection signal is sent to the host computer. The host computer controls the power element to operate, driving the first and second rubber rollers to rotate and actively transport the stretch film towards the object being wrapped, thereby reducing the tension of the stretch film and decreasing the tightness of the stretch film on the object being wrapped. When the stretch film loosens to a certain extent, the detection roller resets under the action of the spring. The detection switch can no longer detect the detection roller, so the power element stops operating, the first and second rubber rollers stop rotating, and the tension of the stretch film increases again. The object being wrapped gradually tightens the stretch film, and the detection roller, under the action of the spring force, tensions the stretch film, adjusting the tension of the stretch film within a certain range. When the first and second rubber rollers rotate, the linear velocity ratio between the first and second rubber rollers is less than 1, which will have a certain stretching effect on the wrapping film between the first and second rubber rollers, thus playing a pre-stretching role. This is beneficial to improving the tension effect of the wrapping film and improving the wrapping packaging quality.
[0010] Optionally, the frame is also provided with a membrane roll rod for placing the membrane roll.
[0011] By adopting the above technical solution, the setting of the film roll rod facilitates the placement of the film roll for winding.
[0012] Optionally, the bottom end of the membrane roll rod is mounted on the frame, and a limiting plate is slidably mounted on the membrane roll rod along the axial direction. A threaded hole is provided through the limiting plate, and a tightening rod is screwed into the threaded hole. The end of the tightening rod abuts against the membrane roll rod.
[0013] By adopting the above technical solution, a limiting plate is set on the membrane roll rod. The limiting plate is fixed at a certain position on the membrane roll rod by screwing in the tightening rod, thereby restricting the sliding of the limiting plate, preventing the membrane roll on the membrane roll rod from moving axially, and preventing the membrane roll from falling off the membrane roll rod.
[0014] Optionally, one end of the first rubber roller and the second rubber roller are meshed by gears, and the transmission ratio between the first gear on the first rubber roller and the second gear on the second rubber roller is less than 1.
[0015] By adopting the above technical solution, the first and second rubber rollers are driven by the meshing of the first and second gears, so that the first and second rubber rollers can rotate and stop simultaneously. At the same time, the transmission ratio is less than 1, that is, the rotational speed of the first rubber roller is less than the rotational speed of the second rubber roller, thereby stretching the wrapping film between the first and second rubber rollers and playing a pre-stretching role.
[0016] Optionally, the power element comprises a motor set arranged on the frame body, and the motor set drives the second rubber roller to rotate through a chain transmission mode.
[0017] By adopting the above technical scheme, the chain transmission mode is simple and reliable, and the cost is low.
[0018] Optionally, a long slot is arranged on the frame body, and the roller shaft of the detection roller is slidingly arranged in the long slot.
[0019] By adopting the above technical scheme, the detection roller can slide in the long slot through the arrangement of the long slot.
[0020] Optionally, one end of the long slot is provided with a fixing bolt, one end of the spring is connected with the fixing bolt, and the other end of the spring is connected with the roller shaft of the detection roller.
[0021] By adopting the above technical scheme, under the elastic force of the spring, the detection roller is driven to move in the long slot, and can be kept at a certain position, thereby keeping the tension of the winding film.
[0022] Optionally, the film winding rod is located on the side of the first rubber roller away from the guide roller, and the center distance between the first rubber roller and the film winding rod is greater than the center distance between the second rubber roller and the film winding rod.
[0023] By adopting the above technical scheme, the position arrangement of the first rubber roller, the second rubber roller, the guide roller and the film winding rod can improve the winding contact surface of the winding film with the first rubber roller and the second rubber roller, and improve the supporting, guiding and conveying effect of the winding film.
[0024] Optionally, the tightening rod is provided with a rotating handle.
[0025] By adopting the above technical scheme, the rotating handle is arranged to facilitate the rotating and tightening operation of the tightening rod.
[0026] In summary, the present application at least has the following beneficial effects:
[0027] 1. The application can support and guide the winding film through the setting of the first rubber roller, the second rubber roller and the guide roller. When the winding film is gradually tightened when the winding object tightens the winding film during winding and packaging, the detection roller moves against the spring elastic force. When the detection switch detects the detection roller, a signal is transmitted to the upper computer. The upper computer controls the power element to operate, drives the first rubber roller and the second rubber roller to rotate, actively transports the winding film to the winding object direction, and further reduces the tension of the winding film. The degree of tightening of the winding film on the winding object is reduced. When the winding film is loosened to a certain extent, the detection roller is reset under the action of the spring. The detection switch cannot detect the detection roller, and the power element stops operating. The first rubber roller and the second rubber roller stop rotating, and the tension of the winding film increases again. The winding object gradually tightens the winding film, and the detection roller tightens the winding film under the action of the spring. The tension of the winding film is adjusted within a certain range. When the first rubber roller and the second rubber roller rotate, the linear speed ratio of the first rubber roller to the second rubber roller is less than 1, which can stretch the winding film between the first rubber roller and the second rubber roller to a certain extent, and has the effect of pre-stretching, which is beneficial to improve the tension effect of the winding film and improve the winding and packaging quality.
[0028] 2. The setting of the film roll rod facilitates the placement of the film roll. The limiting plate is fixed on the film roll rod at a certain position by screwing the tightening rod, thereby limiting the sliding of the limiting plate and preventing the film roll on the film roll rod from moving axially and falling off the film roll rod.
