Example Embodiment

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0020] like Figure 1-3 As shown, an automatic replacement device for plastic film rewinding roller paper tubes includes a paper tube replacement mechanism 2, a vertical plate 8 and a frame 10, and the frame 10 is fixed with two support plates 4 spaced apart from each other and arranged in parallel. , each of the support plates 4 is equipped with a crankshaft 15 through a bearing seat 9, and the other end of the crankshaft 15 is installed on the paper tube replacement mechanism 2 through a bearing, and the paper tube replacement mechanism 2 includes a fixed rod 205 and the material receiving plate 206, the two material receiving plates 206 are welded into an I-shape through the fixed rod 205, and the upper surface of one end of the material receiving plate 206 is equipped with a film roll supporting plate 202 through the guide rod 204, and the The bottom of the frame 10 is equipped with a slide rail 7, and the two vertical plates 8 are movably installed at both ends of the slide rail 7 respectively. The vertical plate 8 is installed on the same threaded mandrel 11 , and the middle part of the threaded mandrel 11 is connected to the output end of the servo motor 16 installed on the frame 10 through transmission.
[0021] One end of the support plate 4 is fixed with a paper tube material holder 1 , and the other end of the support plate 4 is fixed with a film roll material holder 5 . Both the paper tube material rack 1 and the film roll material rack 5 are fixed in an inclined manner. The lowest end of the paper tube material rack 1 is located on the plane where the support plate 4 is located and is tilted upwards to prevent the paper tube from falling. The paper tube material rack 1 The lowest end is provided with a missing groove for the passage of the material receiving plate 206, and the highest end of the film coil rack 5 is located on the plane where the support plate 4 is located and is provided with a missing groove for the passage of the material receiving plate 206. The lowest end of the film coil rack 5 The end is tilted up to prevent the roll from falling off.
[0022] The material receiving plate 206 is provided with a paper tube positioning groove 201 , and the crankshaft 15 is installed on the material receiving plate 206 . The paper tube positioning groove 201 has a concave shape, and is used to lift the paper tube when the material receiving plate 206 passes through, and transport it to the axis where the support shaft 12 is located.
[0023] The crankshaft 15 is connected with the transmission shaft 14 installed on the frame 10 through a chain, and the transmission shaft 14 is driven by the second motor 6 installed on the frame 10 . The output end of the second motor 6 is equipped with a reducer with a brake, and the second motor 6 is used to drive the transmission shaft 14 to rotate simultaneously, thereby providing power to each crankshaft 15, driving the paper tube replacement mechanism 2 to rotate, and periodically changing the paper tube It can be lifted and lowered with the winding roller, and can stop and maintain the paper roll changing mechanism 2 at the required height.
[0024] The vertical board 8 is located on the outer side of the supporting board 4 . The vertical board 8 is not disturbed by the support board 4 when it moves to the outside.
[0025] One of the support shafts 12 is connected to the output shaft of the first motor 3 installed on the vertical plate 8 , and a limiting plate 13 is welded and fixed on the support shaft 12 . The first motor 3 is used to drive one of the supporting seats 12 to provide power to the paper roll to realize the winding operation of the film.
[0026] The screw rod 11 is a left-right screw screw rod, and the two vertical plates 8 are respectively symmetrically installed on opposite thread segments. The threaded mandrel 11 can be driven to rotate by the servo motor 16, so that the two vertical plates 8 are pushed away or approached toward the outside, the reel is clamped and the wound film roll is released.
[0027] A spring 203 is sleeved on the guide rod 204 . The spring 203 can be used to buffer the film roll when it falls, so as to avoid damage to the film on the film roll.
[0028] Specifically, when in use, the paper tube is placed on the paper tube material rack 1, and the paper tube is rolled to the lowest point of the paper tube material rack 1 under the action of gravity in order to wait for use. First, the screw rod 11 is driven under the action of the servo motor 16. , thereby increasing the distance between the vertical boards 8 until the distance between the two support shafts 12 is greater than the length of the paper tube, then the movement is stopped, and then the second motor 6 is started to drive the paper tube replacement mechanism 2. In the paper tube replacement mechanism 2 During the rotation process, the end with the paper tube positioning groove 201 passes under the paper tube material rack 1 to pick up a paper tube, and as the paper tube replacement mechanism 2 moves, the paper tube is transported to the supporting shaft 12 coaxial position, stop the paper tube replacement mechanism 2, and then start the servo motor 16 to drive the vertical plates 8 close to each other, insert the support shaft 12 into the inside of the paper tube until the limit plate 13 on the support shaft 12 clamps the paper tube , then start the servo motor 16 to move the paper tube replacement mechanism 2 to the lowest position, complete the feeding of the paper tube, under the action of the first motor 3, drive the paper tube to wind the film, after the winding is completed, start the second The motor 6 drives the paper tube replacement mechanism 2. With the movement of the paper tube replacement mechanism 2, a paper tube is picked up again. At the same time, the film roll supporting plate 202 moves under the film roll and fits the film roll. Stop the second motor 6 and start The servo motor 16 drives the vertical plate 8 away, pulls the support shaft 12 out of the reel, and the film roll falls on the film roll supporting plate 202, and then starts the second motor 6 again to drive the paper tube replacement mechanism 2 to continue to rotate, so that the film roll Falling on the film roll frame 5 and rolling out, the paper tube is transported to the coaxial position of the support seat 12 for installation. Repeat the above cycle to automatically replace the paper tube and film roll.
[0029] Finally, it should be noted that: the above is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still The technical solutions recorded in the foregoing embodiments may be modified, or some of the technical features may be replaced equivalently, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the within the protection scope of the present invention.
