Description

Technical Field

[0001] This utility model relates to the technical field of film production equipment, and in particular to a movable mounting device for a plastic film winding shaft. Background Technology

[0002] In the initial stages of film preparation, process parameters are not yet stable. Pump speed, liquid pressure, and shear force are difficult to reach a dynamic balance in a short time, resulting in significant quality fluctuations in the initial film section. Specifically, this section often exhibits uneven thickness distribution, with alternating areas of excessive thickness or thinness, and even noticeable flow lines at the film edges. This not only affects the appearance but may also negatively impact subsequent processes. Therefore, in actual production, this substandard section of film needs to be separately wound up and removed to ensure the yield and consistency of the main product.

[0003] The current installation method for film rolls presents significant operational inconveniences. Operators must first remove the entire winding shaft from the equipment before they can insert the empty roll into the shaft and secure it. After the roll is installed, both ends of the winding shaft must be returned to their original positions. Throughout the process, disassembly and installation are repeated, increasing the number of steps and impacting production efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a movable mounting device for a plastic film winding shaft.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a movable mounting device for a plastic film take-up shaft, comprising a fixed base, a push rod, and a transition shaft for connecting to the take-up shaft. A shaft sleeve is installed at the fixed base, and a movable rod for movably connecting to the transition shaft is slidably arranged at the shaft sleeve. A hinge is movably connected between the movable rod and the push rod. One end of the push rod is hinged to a protrusion at the shaft sleeve, and the hinge is provided with a positioning groove that mates with the protrusion.

[0006] To further elaborate, the left and right sides of the positioning groove are respectively provided with a first contact surface and a second contact surface, and the protrusion is provided with a first inclined surface and a second inclined surface. When the hinge is engaged with the protrusion of the shaft cylinder, the first contact surface of the positioning groove contacts the first inclined surface of the protrusion of the shaft cylinder, and the second contact surface of the positioning groove contacts the second inclined surface of the protrusion of the shaft cylinder.

[0007] To further elaborate, one end of the movable rod is hinged to the hinge member, and the other end of the movable rod is provided with a limiting connector for connecting to the adapter shaft, and the adapter shaft can rotate freely at the limiting connector.

[0008] To elaborate further, the limiting connector is provided with an inner limiting groove, and the convex ring portion at the shaft end of the adapter shaft is located in the inner limiting groove.

[0009] To further elaborate, a buffer ring is provided in the inner cavity of the shaft cylinder. One side of the buffer ring is in contact with the shaft cylinder, and the other side of the buffer ring is provided with several elastic abutment parts for abutting against the outer ring surface of the movable rod.

[0010] To elaborate further, the elastic contact portion is provided with several branch tentacles, and the branch tentacles are pyramidal in shape.

[0011] To further elaborate, one end of the take-up shaft is fixedly connected to the adapter shaft, and the other end of the take-up shaft is slidably inserted into the take-up drive unit.

[0012] The advantages of this utility model are as follows: This utility model has a novel structure and ingenious design. Compared with the prior art, this utility model does not require disassembling the entire take-up shaft. The adapter shaft can be controlled by pushing the rod, thereby controlling the take-up shaft to be pulled out or inserted back from the take-up drive unit. This makes it convenient to install the roll used for taking up film, reduces the difficulty of changing the roll, and improves work efficiency. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0023] Combined with appendix Figure 1 and attached Figure 2 As shown, a movable mounting device for a plastic film take-up shaft includes a fixed base 10, a push rod 31, and a transition shaft 43 for connecting to the take-up shaft 50. A shaft cylinder 20 is installed at the fixed base 10, and a movable rod 41 for movably connecting to the transition shaft 43 is slidably installed at the shaft cylinder 20. The movable rod 41 slides and extends at the shaft cylinder 20. A hinge 32 is movably connected between the movable rod 41 and the push rod 31. One end of the push rod 31 is hinged to a boss portion 21 at the shaft cylinder 20. The hinge 32 is provided with a positioning groove portion 321 that cooperates with the boss portion 21.

[0024] Combined with appendix Figure 5 To be continued Figure 7 As shown, one end of the movable rod 41 is hinged to the hinge member 32, and the other end of the movable rod 41 is provided with a limiting connector 42 for connecting to the adapter shaft 43. The adapter shaft 43 can rotate freely at the limiting connector 42, and the limiting connector 42 is provided with an inner limiting groove 421. The shaft end protruding ring 431 of the adapter shaft 43 is located in the inner limiting groove 421.

[0025] Combined with appendix Figure 3 Appendix Figure 5 and attached Figure 7As shown, the left and right sides of the positioning slot 321 are respectively provided with a first contact surface 3211 and a second contact surface 3212, and the boss 21 is provided with a first inclined surface 211 and a second inclined surface 212. When the hinge 32 is engaged with the boss 21 of the shaft cylinder 20, the first contact surface 3211 of the positioning slot 321 contacts the first inclined surface 211 of the boss 21 of the shaft cylinder 20, and the second contact surface 3212 of the positioning slot 321 contacts the second inclined surface 212 of the boss 21 of the shaft cylinder 20, thereby locking and fixing the movable rod 41.

[0026] To prevent the push rod 31 from being excessively pressed down, a buffer ring 22 is provided in the inner cavity of the shaft sleeve 20. (See attached...) Figure 3 and attached Figure 8 As shown, one side of the buffer ring 22 is in contact with the shaft cylinder 20, and the other side of the buffer ring 22 is provided with several elastic contact portions 221 for abutting against the outer ring surface 411 of the movable rod 41. The elastic contact portions 221 are provided with several branch tentacles 2211, and the branch tentacles 2211 are pyramidal in shape.

[0027] Combined with appendix Figure 1 As shown, one end of the take-up shaft 50 is fixedly connected to the adapter shaft 43, and the other end of the take-up shaft 50 is slidably inserted into the take-up drive unit 60. The take-up drive unit 60 is specifically composed of an existing drive motor and reducer, so it will not be described in detail here.

[0028] When installing the roll used for winding the film at the take-up shaft 50, combine with the attached Figure 2 and attached Figure 3 As shown, the push rod 31 drives the movable rod 41 via the hinge 32. The movable rod 41 drives the take-up shaft 50 to be pulled out from the take-up drive unit 60 via the adapter shaft 43. The drum is then inserted into the take-up drive unit 60 from the end that has been pulled out via the take-up shaft 50. After the drum is installed, it is combined with the attached... Figure 4 and attached Figure 5 As shown, the push rod 31 is pushed counterclockwise. The push rod 31 drives the movable rod 41 through the hinge 32. The movable rod 41 drives the take-up shaft 50 to slide back into the take-up drive unit 60 through the adapter shaft 43. Then the take-up drive unit 60 can drive the take-up shaft 50 to rotate and take up the film.

[0029] Compared with the prior art, this utility model does not require disassembling the entire take-up shaft. The adapter shaft 43 can be controlled by the push rod 31, which in turn controls the take-up shaft 50 to be pulled out or inserted back from the take-up drive unit 60. This makes it convenient to install the roll used for taking up film, reduces the difficulty of changing the roll, and improves work efficiency.
