As specific embodiment, the utility model discloses an IMD film material loading structure of embodiment, it includes carrier 1, wheel carrier subassembly 2 and rotary power spare 3, and wheel carrier subassembly 2 includes with carrier 1 articulated wheel carrier 29, rotary power spare 3 and wheel carrier 29 drive connection. The wheel frame 29 is used for arranging the film roll 9, and the film roll 9 can rotate along with the wheel frame 29 by sleeving the film roll 9 on the wheel frame 29. One end of the wheel frame 29 is provided with a wheel frame limiting body 298, and the wheel frame limiting body 298 is used for limiting the position of the film roll 9.

In a specific embodiment, the power transmission device further comprises a transmission belt 32, the wheel carrier 29 is fixedly provided with a driven disc 293, the rotating output end of the rotating power member 3 is fixedly provided with a driving disc 31, and the transmission belt 32 bypasses the driving disc 31 and the driven disc 293, so that the rotating power member 3 is in driving connection with the wheel carrier 29, in other words, the rotating output end of the rotating power member 3 rotates to enable the wheel carrier 29 to rotate along with the rotating output end. The rotary power member 3 is a rotary power device such as a motor. The belt 32 is a round belt (circular in cross section) having elasticity, such as a PU round belt. The driven plate 293 and the driving plate 31 are provided with a driving belt groove (not shown) with a segment-shaped section. The belt 32 is located within the belt groove. Compared with a chain transmission mode and the like, the transmission belt 32 can slip relative to the driven disc 293 or the driving disc 31, and the rotary power member 3 is prevented from being overloaded and damaged.

The IMD film feeding structure of the embodiment of the utility model also comprises a contact switch 49, an elastic part 411 and a control part 4 hinged with the carrier 1; for example, the control member 4 is hinged to the carrier 1 by means of a pin fixed to the carrier 1, passing through a hinge 48 of the control member 4.

The wheel frame assembly 2 further comprises a tensioning carrier 21 hinged with the carrier 1, a tensioning body 22 is arranged at the top end of the tensioning carrier 21, and the tensioning body 22 is positioned at the left side of the wheel frame 29 (as shown in fig. 7, positioned at the left side of a vertical plane passing through the axis of the wheel frame shaft 299). For example, the wheel frame 29 is fixedly provided with a wheel frame shaft 299, two ends of the wheel frame shaft 299 are respectively connected with the carrier 1 through bearings (not shown in the drawing), so that the wheel frame 29 is hinged with the carrier 1, the tensioning carrier 21 is hinged with the wheel frame shaft 299 through a wheel frame bearing 218, so that the tensioning carrier 21 is hinged with the carrier 1, and the wheel frame 29 and the tensioning carrier 21 can respectively rotate relative to the carrier 1.

The control member 4 is L-shaped as a whole, and the two ends of the hinged part (i.e. the hinged part 48) of the control member 4 and the carrier 1 are respectively a contact end 41 and a control end 42.

The contact end 41 abuts against the bottom of the tension carrier 21, and a control protrusion 211 is arranged above the contact end 41 at the bottom of the tension carrier 21.

The elastic members 411 are respectively connected with the control member 4 such that the contact ends 41 have a tendency to approach the tension carrier 21.

The contact switch 49 is fixed on the carrier 1, and the rotary power member 3 is in control connection with the contact switch 49. The contact switch 49 may be an electric switch to control the rotary power unit 3 as a motor, or an air valve to control the rotary power unit 3 as a rotary cylinder.

The working principle is that before use, the film roll 9 is sleeved on the wheel carrier 29, and the end of the film roll 9 is led out and bypasses the tensioning carrier 21 and the reversing wheel 8 (the reversing wheel 8 can be arranged on the carrier 1 or on other frames), and then is connected to a process, for example, a buffer process before a screen printing process (the buffer process is that the film before the screen printing input wheel properly falls down so as to be convenient for the film to intermittently enter the screen printing process). The end of the film roll 9 is divided into a supported section 91 and a flattening output section 92 by the reversing wheel 8.

When the device is used (at this time, the flattening output section 92 stops moving horizontally), the tension body 22 tends to rotate leftwards due to the dead weights of the tension body 22 and the tension carrier 21, so that the tension body 22 abuts against the abutted section 91; this time, the stop state.

As shown in fig. 7, when the flat output section 92 continuously moves horizontally to output, the supported section 91 supports the tensioning body 22 to rotate the tensioning carrier 21 rightward, the control protrusion 211 supports the contact end 41 to rotate the control member 4, and the control end 42 supports the triggered end 491 to trigger the contact switch 49, so that the rotating power member 3 operates to release the film from the film roll 9. In this process, the abutting of the abutted section 91 by the tension body 22 causes the flattened output section 92 to be tensioned.

When the horizontal movement of the flattening output section 92 is stopped (for example, a production line failure, which is a process that causes the flattening output section 92 to stop), the tensioning body 22 is reset, and the rotary power member 3 stops operating, so that the film roll 9 stops releasing the film. The control member 4 is reset by the elastic member 411.

As can be seen from the above, the rotation of the film roll 9 can be controlled in accordance with the state of movement of the flat output section 92 while the tension of the flat output section 92 is ensured.

As a specific embodiment, the tension carrier 21 is provided with a stopper groove 219, and the carrier 1 is provided with a stopper body 19 inserted into the stopper groove 219. The angle at which the tension carrier 21 rotates by its own weight can be restricted, avoiding an excessively large rotation angle of the tension carrier 21 when the horizontal movement of the flattening output section 92 is stopped.

In a specific embodiment, the elastic member 411 is a tension spring, and two ends of the elastic member are respectively connected to the contact terminal 41 and the carrier 1.

In a specific embodiment, the contact end 41 is hinged to the roller 7, and the contact end 41 abuts against the tension carrier 21 through the roller 7. When the control protrusion 211 abuts against the contact end 41, the package control member 4 can be ensured to rotate smoothly.

In a specific embodiment, the control end 42 is fixedly provided with a stop portion 421, and the stop portion 421 abuts against the output end of the rotary power element 3 in the stop state. The braking effect can be realized when the vehicle is in a stop state.
