[0017] In the figure: 1 mounting frame, 2 detection shaft, 3 driving screw, 4 base, 41 cylinder, 42 mounting plate, 43 pressure sensor, 5 sleeve, 6 fixing frame, 61 sliding rod, 62 elastic column, 7 roller shaft, 71 rubber sleeve. DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-3The utility model provides a technical solution: a tube core detection device for aluminum foil, comprising a mounting frame 1, a detection shaft 2 is mounted on the upper end of the side of the mounting frame 1, a base 4 whose moving direction is parallel to the detection shaft 2 is provided on the lower side of the detection shaft 2, a mounting plate 42 with adjustable height is provided on the upper side of the base 4, a support for supporting the tube core is horizontally slidably provided on the upper side of the mounting plate 42, a pressure sensor 43 is provided on the side of the mounting plate 42 for detecting the resistance encountered by the support when the support moves, the support comprises a fixing frame 6, two symmetrically arranged rollers 7 are rotatably provided on the upper end of the side of the fixing frame 6, a rubber sleeve 71 is provided on the roller 7, a slide rod 61 is provided on the lower end of the fixing frame 6, and a sleeve 5 is provided on the mounting plate 42 , and the slide rod 61 is slidably arranged in the sleeve 5, and the side of the fixing frame 6 corresponding to the pressure sensor 43 is provided with an elastic column 62 in contact with the pressure sensor 43. When the support member drives the tube core to move, if the tube core is not straight, the resistance of the tube core to the detection shaft 2 during the movement becomes greater and may even cause the tube core to be unable to move. The tube core drives the support member to move slower or stop. Since the base 4 is still moving normally, the support member will cause relative displacement between the base 4 and the mounting plate 42. The support member squeezes the pressure sensor 43 through the elastic column 62. The pressure on the pressure sensor 43 increases, and when the pressure sensor 43 detects that the value exceeds a certain value, it means that the straightness of the tube core does not meet the standard and there is deformation.

[0020] Furthermore, one end of the detection shaft 2 away from the mounting frame 1 is chamfered to facilitate the tube core to be mounted on the detection shaft 2 .

[0021] Furthermore, a driving screw 3 for driving the base 4 to move is provided on the lower side of the mounting frame 1, and the driving screw 3 is threadedly connected to the base 4, and a motor for controlling the rotation of the driving screw 3 is provided on the mounting frame 1. The motor drives the driving screw 3 to rotate, and the driving screw 3 drives the base 4 to move, and the base 4 drives the tube core to move through the support member.

[0022] Furthermore, a cylinder 41 is provided on the upper surface of the base 4 for controlling the up and down movement of the mounting plate 42, so as to facilitate adjustment of the height of the support member; in the non-detection state, the roller 7 with a rubber sleeve 71 supports the end of the detection shaft 2 away from the mounting frame 1.

[0023] Furthermore, a driving motor is provided on one side of the fixed frame 6, and pulleys are provided on the output shaft of the driving motor and the end of one of the roller shafts 7. The two pulleys are connected by a belt. When the tube core is completely sleeved on the detection shaft 2, the driving motor is controlled by an external controller, and the driving motor drives the roller shaft 7 to rotate through the transmission of the pulley and the belt. The roller shaft 7 drives the tube core to rotate on the detection shaft 2, and the outer surface of the tube core is observed and detected during the rotation of the tube core.

[0024] The surface of the detection shaft 2 is chrome-plated to increase the surface smoothness of the detection shaft 2.

[0025] The motor, drive motor and pressure sensor 43 used in the present invention are all commonly used electrical components in the prior art. Their working methods and circuit structures are well-known technologies and will not be elaborated here. The motor, drive motor and pressure sensor 43 are all electrically connected to the external controller, and the external controller can display the pressure value detected by the pressure sensor 43.

[0026] When using:

[0027] In the non-detection state, the roller shaft 7 covered with the rubber sleeve 71 supports the end of the detection shaft 2 away from the mounting frame 1;

[0028] In the detection state, the control cylinder 41 is shortened, and the cylinder 41 drives the mounting plate 42 downward, and the mounting plate 42 drives the support member downward. At this time, the end of the detection shaft 2 away from the mounting frame 1 is in a suspended state;

[0029] The motor is controlled by an external controller to rotate the driving screw 3, which drives the base 4 to move away from the mounting frame 1, thereby moving the roller 7 away from the side of the mounting frame 1.

[0030] Place the tube core on the roller 7 and control the cylinder 41 to extend. After the cylinder 41 extends, it drives the mounting plate 42 to move upward. The mounting plate 42 drives the support member to move upward. The support member drives the tube core to move up a certain distance and make the center axis of the tube core coincide with the center axis of the detection shaft 2.

[0031] The motor is controlled by an external controller to rotate in the opposite direction. The driving screw 3 drives the base 4 to move toward the mounting frame 1. The base 4 drives the mounting plate 42 to move via the cylinder 41. The mounting plate 42 drives the tube core to move toward the mounting frame 1 via the support member.

[0032] During the movement of the tube core, it is gradually sleeved on the detection shaft 2. During this process, there is a certain amount of friction between the detection shaft 2 and the tube core. When the straightness of the tube core is good, the friction force changes little, and the relative position between the base 4 and the support member changes little. After the tube core is completely sleeved on the detection shaft 2, the drive motor is controlled by an external controller to work. The drive motor drives the roller shaft 7 to rotate through the transmission of the pulley and the belt. The roller shaft 7 drives the tube core to rotate on the detection shaft 2. During the rotation of the tube core, its outer surface is observed and inspected.

[0033] When the straightness of the tube core is not good, the resistance of the detection shaft 2 during the movement of the tube core becomes greater and may even cause the tube core to be unable to move. At this time, since the base 4 moves normally, the movement speed of the tube core slows down or even stops moving, so that the tube core drives the support to move slower. In this process, the roller 7 drives the slide bar 61 to move slower through the fixed frame 6, while the sleeve 5 moves normally. Therefore, the fixed frame 6 and the slide bar 61 move relative to the sleeve 5. The fixed frame 6 drives the elastic column 62 to squeeze the pressure sensor 43. The pressure on the pressure sensor 43 increases, and when the pressure sensor 43 detects that the value exceeds a certain value, it means that the straightness of the tube core does not meet the standard and there is deformation.

[0034] The utility model can support and transport the tube core, and automatically detect whether the tube core is straight during the tube core transportation process with high detection accuracy. It can also drive the tube core with good straightness to rotate, so as to observe and detect the outer surface of the tube core, which can save manpower and improve work efficiency. It is simple to operate and easy to use.

[0035] The undisclosed parts of the present invention are all prior art, and their specific structures, materials and working principles will not be described in detail. Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
