A positioning plate 4 is fixedly installed on the side of the base plate 1 away from the unloading mechanism 3, a rotating shaft 5 is installed horizontally through the inside of the positioning plate 4, a film roll is sleeved on the outer wall of the rotating shaft 5, and a limiting mechanism 6 for limiting the film roll is provided on the top wall of the rotating shaft 5; moving wheels 101 are installed at the four corners of the bottom wall of the base plate 1, and a fixing mechanism 7 is provided on one side of the moving wheel 101. The fixing mechanism 7 includes a vertically movable support seat 71, and a rubber pad 72 is connected to the outside of the support seat 71.

[0029] In this embodiment, a sliding groove 102 is formed on the inner bottom wall of the bottom plate 1 , and a pulley is mounted on the bottom wall of the threaded seat 22 , and the pulley is slidably connected to the inside of the sliding groove 102 .

[0030] It should be noted that the movement of the unloading mechanism 3 can maintain good balance.

[0031] In this embodiment, the unloading mechanism 3 includes an electric push rod 31, which is fixedly mounted on the top wall of the threaded seat 22. A support plate 32 is installed at the end of the actuator rod of the electric push rod 31. A support groove 33 is opened on the top of the support plate 32. A bidirectional screw 34 is rotatably connected inside the support groove 33. A second motor 35 is installed at one end of the support plate 32. The bidirectional screw 34 passes through one end of the support plate 32 and is connected to the output end of the second motor 35. The two ends of the outer wall of the support plate 32 are symmetrical and threadedly connected with clamping plates 36. The bottom ends of the two clamping plates 36 are both slidably connected to the inside of the support groove 33.

[0032] The one-way screw 21 drives the threaded seat 22 to move in the opposite direction, and the one-way screw 21 drives the threaded seat 22 to move. The pulley at the bottom of the threaded seat 22 slides inside the slide groove 102, and the threaded seat 22 drives the unloading mechanism 3 to move horizontally, and moves to one end of the film roll close to the positioning plate 4. The upward extension of the electric push rod 31 causes the two clamping plates 36 to move to the two sides of the film roll. Then, the second motor 35 is started to drive the bidirectional screw 34 to rotate, so that the bottom ends of the two clamping plates 36 move close to each other inside the support groove 33 until the side walls of the two clamping plates 36 abut against the side walls of the film roll. The one-way screw 21 drives the threaded seat 22 to move in the opposite direction, so that the clamped film roll starts to move, and presses down the limiting protrusion 63 again until the film roll is moved to the disengagement from the rotating shaft 5, completing the automatic unloading of the film roll.

[0033] In this embodiment, the limiting mechanism 6 includes a plurality of limiting grooves 61 opened on the top wall of the rotating shaft 5, and a spring 62 is fixedly connected inside the limiting groove 61.

The limiting protrusion block 63 moves up and down inside the limiting groove 61, and the limiting protrusion block 63 can abut against one end of the film roll.

[0034] It should be noted that when the film roll is being moved, a downward squeezing force is generated on the limiting protrusion 63, causing the spring 62 to be compressed and drive the limiting protrusion 63 to move to the inside of the limiting groove 61. When the film roll is completely sleeved on the outside of the rotating shaft 5, the limiting protrusion 63 moves upward after being restored by the elastic force of the spring 62, so that it is against the two ends of the film roll, thereby limiting and fixing the film roll.

[0035] In this embodiment, the fixing mechanism 7 further includes a cylinder 73 , which is fixedly mounted around the bottom wall of the base plate 1 , the upper end of the support seat 71 is connected to the end of the actuator rod of the cylinder 73 , and one side of the rubber pad 72 is connected to an auxiliary plate 74 .

[0036] It should be noted that the downward extension of the actuator rod of the cylinder 73 drives the support seat 71 downward until the bottom wall of the support seat 71 contacts the ground, and the rubber pad 72 also contacts the ground, which can increase the contact area with the ground and increase the friction, thereby improving the stability of the device. The external force of the auxiliary plate 74 can assist the support seat 71 in moving downward.

[0037] In this embodiment, a first fixed plate 8 is symmetrically connected to one side of the top wall of the base plate 1, a first feeding tube 9 is installed on the upper inner side of the first fixed plate 8, a second fixed plate 10 is connected to one side of the first fixed plate 8, a second feeding tube 11 is installed on the lower inner side of the second fixed plate 10, a third fixed plate 12 is connected to one side of the second fixed plate 10, and a third feeding tube 13 is installed on the upper inner side of the third fixed plate 12.

[0038] It should be noted that the film passes from the bottom of the film roll and is wound on the third feed drum 13, passes from the top of the third feed drum 13 and is wound downward on the second feed drum 11, and passes from the bottom of the second feed drum 11 and is wound on the top of the first feed drum 9.

[0039] In this embodiment, a third motor 14 is installed on the outer wall of the third fixed plate 12, the output shaft of the third motor 14 passes through the two third fixed plates 12, the third feeding barrel 13 is sleeved on the output shaft, the outer end of the output shaft is connected to the first moving wheel, the outer end of the rotating shaft 5 is connected to the second moving wheel, and the first moving wheel and the second moving wheel are connected by a conveyor belt 15.

[0040] It should be noted that the third motor 14 is started by using power to drive the output shaft to rotate, the output shaft drives the third feeding drum 13 to rotate, and at the same time the output shaft drives the first moving wheel to rotate, the first moving wheel drives the conveyor belt 15 and the second moving wheel to transmit, the second moving wheel drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the film roll, so as to realize the feeding of the film.

[0041] The working principle of the present invention is as follows: the device moves under the action of the four moving wheels 101. After moving, the downward extension of the cylinder 73 actuator rod drives the support seat 71 downward until the bottom wall of the support seat 71 contacts the ground. At the same time, the rubber pad 72 also contacts the ground, which can increase the contact area with the ground and increase the friction force, thereby improving the stability of the device. The external force of the auxiliary plate 74 can assist the support seat 71 to move downward, and one end of the film roll is sleeved on the outside of the rotating shaft 5. When the film roll is sleeved and moved, it will produce a downward impact on the limiting protrusion 63. The squeezing force causes the spring 62 to be compressed and drives the limiting protrusion 63 to move to the inside of the limiting groove 61. When the film roll is completely sleeved on the outside of the rotating shaft 5, the limiting protrusion 63 moves upward after being restored by the elastic force of the spring 62, so that it abuts the end of the film roll, thereby limiting and fixing the film roll. The film is wound on the third feeding drum 13, passes through the top of the third feeding drum 13 and is wound downward on the second feeding drum 11, passes through the bottom of the second feeding drum 11 and is wound on the top of the first feeding drum 9, and the power supply is used to start the third motor 14 to drive the output shaft. The output shaft drives the third feeding cylinder 13 to rotate, and at the same time the output shaft drives the first moving wheel to rotate, the first moving wheel drives the conveyor belt 15 and the second moving wheel to transmit, the second moving wheel drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the film roll to rotate, so as to realize the feeding of the film, and the first motor 2 is started by power supply to drive the one-way screw 21 to rotate, the one-way screw 21 drives the threaded seat 22 to move, the pulley at the bottom of the threaded seat 22 slides inside the slide groove 102, and the threaded seat 22 drives the unloading mechanism 3 to move horizontally, and moves to the end of the film roll close to the positioning plate 4, through the electric push rod The upward extension of 31 causes the two clamping plates 36 to move to one end of the film roll, and then the second motor 35 is started to drive the bidirectional screw 34 to rotate, so that the bottom ends of the two clamping plates 36 move closer to each other inside the support groove 33 until the side walls of the two clamping plates 36 abut against the end of the film roll, and then the one-way screw 21 drives the threaded seat 22 to move in the opposite direction, so that the clamped film roll begins to move outside the rotating shaft 5, and the limiting protrusion 63 is pressed down again until the film roll is moved away from the rotating shaft 5, completing the automatic unloading of the film roll.

It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model.
