Description

Technical Field

[0001] This utility model relates to a winding device, specifically a winding device for producing plastic film, and belongs to the field of plastic film production technology. Background Technology

[0002] Plastic film, as a printing substrate, is used as packaging after printing. It has advantages such as being lightweight and transparent, moisture-proof and oxygen-resistant, having good airtightness, being tough and fold-resistant, having a smooth surface, protecting goods, and reproducing the shape and color of goods. This involves the production of winding devices for producing plastic film.

[0003] A winding device for plastic film production disclosed in Chinese Patent Application Publication CN217996210U involves winding the film by placing a roll on a first clamping plate and a second clamping plate. A first locking nut is then rotated to bring the first clamping plate into contact with the inner wall of the roll, followed by a second locking nut. A motor is then started, driving a rotating rod to rotate, which in turn rotates the roll, thus winding the film. (During winding, the film is positioned by a limiting component on the base, preventing positional deviation. The limiting component includes a first clamping plate on the base, a rod on the first clamping plate, and a second clamping plate on the rod.) After winding, the first and second locking nuts are loosened, and the first and second clamping plates are rotated to facilitate disassembly of the roll. This simple structure allows for easy disassembly and installation of the roll.

[0004] The solutions in the above patents make the roll easy to disassemble and install through a simple structure. However, when producing plastic films of different specifications, the required roll size will be different. The device can only install rollers of a fixed size, which reduces production flexibility.

[0005] Therefore, a winding device for producing plastic film is proposed here. Utility Model Content

[0006] This utility model proposes a winding device for producing plastic film, which can install rolls of different sizes according to production needs.

[0007] This utility model is achieved through the following technical solution: a winding device for producing plastic film, including a base, on which an installation component is provided.

[0008] The mounting assembly includes a second slide groove formed on the base. A bidirectional threaded rod is rotatably connected to the inner wall of the second slide groove, and one end of the bidirectional threaded rod extends to the outside of the base. Two threaded blocks are threadedly connected to the outer surface of the bidirectional threaded rod, and the outer surface of the threaded blocks is slidably connected to the inner wall of the second slide groove. A fixing plate is fixed to the upper surface of the threaded blocks, and the bottom surface of the fixing plate is in slidable contact with the upper surface of the base. Mounting plates are rotatably connected to the adjacent sides of the two fixing plates.

[0009] Furthermore, a throttle is fixed to one end of the bidirectional threaded rod located outside the base, and a rotary motor is fixed to the outside of the fixing plate, with the output shaft end of the rotary motor passing through the fixing plate and fixed to one side of the mounting plate.

[0010] Furthermore, a roller is provided between the two fixed plates, and an installation groove is provided on the side of the two mounting plates that are close to each other. Mounting blocks are fixed at both ends of the roller, and the mounting blocks are inserted into the mounting grooves. The diameter of the mounting grooves is larger than the diameter of the mounting blocks. The mounting plates and mounting blocks are respectively provided with a first threaded hole and a second threaded hole. Bolts are provided on the mounting blocks, and the bolts are connected to the first threaded hole and the second threaded hole in sequence.

[0011] Furthermore, an electric push rod is fixed to the upper surface of the base, and an arc-shaped plate is fixed to the top of the electric push rod, with the arc-shaped plate located below the drum.

[0012] Furthermore, a first sliding groove is provided on the upper surface of the base, a sliding rod is fixed to the inner wall of the first sliding groove, a slider is slidably connected to the outer surface of the sliding rod, and the upper surface of the slider is fixed to the bottom surface of the fixing plate.

[0013] Furthermore, two mounting plates are fixed to the upper surface of the base, and two guide rollers are rotatably connected to the side of the two mounting plates that are close to each other.

[0014] This utility model provides a winding device for producing plastic film, which has the following beneficial effects:

[0015] 1. This plastic film production winding device places the roll onto an arc-shaped plate, then activates an electric push rod to move the arc-shaped plate. The arc-shaped plate moves the roll between two mounting discs. Once the roll is between the two mounting discs, a throttle is turned to rotate a bidirectional threaded rod. The rotation of the bidirectional threaded rod causes two threaded blocks to move closer to each other. The threaded blocks move a fixing plate, which in turn moves the mounting discs. This allows the mounting blocks on the roll to be inserted into the mounting slots on the mounting discs. Bolts are then threaded through the first and second threaded holes to fix the mounting discs and mounting blocks. This allows for the installation and fixing of rolls of different sizes according to production needs. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0027] Please see Figures 1-4 The present invention proposes the following implementation scheme: a winding device for producing plastic film, including a base 1, on which an installation component 2 is provided.

[0028] Please refer to this carefully. Figure 3 and Figure 4The mounting component 2 includes a second slide groove 201 formed on the base 1. A bidirectional threaded rod 202 is rotatably connected to the inner wall of the second slide groove 201, and one end of the bidirectional threaded rod 202 extends to the outside of the base 1. Two threaded blocks 203 are threadedly connected to the outer surface of the bidirectional threaded rod 202, and the outer surface of the threaded blocks 203 is slidably connected to the inner wall of the second slide groove 201. A fixing plate 204 is fixed to the upper surface of the threaded blocks 203, and the bottom surface of the fixing plate 204 is slidably in contact with the upper surface of the base 1. A mounting plate 205 is rotatably connected to the side of the two fixing plates 204 that are close to each other.

[0029] A throttle 207 is fixed to one end of the bidirectional threaded rod 202 located outside the base 1. A rotary motor 206 is fixed to the outside of the fixing plate 204, and the output shaft end of the rotary motor 206 passes through the fixing plate 204 and is fixed to one side of the mounting plate 205.

[0030] A drum 3 is provided between two fixed plates 204. An installation groove 208 is provided on the side of the two mounting plates 205 that are close to each other. An installation block 301 is fixed at both ends of the drum 3 and the installation block 301 is inserted into the installation groove 208. The diameter of the installation groove 208 is larger than the diameter of the installation block 301 to facilitate the insertion of the installation block 301 into the installation groove 208. A first threaded hole 209 and a second threaded hole 302 are respectively provided on the mounting plate 205 and the installation block 301. A bolt 10 is provided on the installation block 301 and the bolt 10 is connected to the first threaded hole 209 and the second threaded hole 302 in sequence.

[0031] An electric push rod 8 is fixed on the upper surface of the base 1. An arc plate 9 is fixed at the top of the electric push rod 8 and the arc plate 9 is located below the drum 3. The electric push rod 8 can drive the arc plate 9 to move the center point of the drum 3 to be parallel to the center point of the fixed plate 204.

[0032] The drum 3 is placed on the arc plate 9, and then the electric push rod 8 is activated to move the arc plate 9. The arc plate 9 can move the drum 3 between the two mounting plates 205. When the drum 3 is between the two mounting plates 205, the double-threaded rod 202 is rotated by turning the handle 207. The rotation of the double-threaded rod 202 can move the two threaded blocks 203 closer to each other. The threaded blocks 203 can move the fixing plate 204, and the fixing plate 204 can move the mounting plate 205, so that the mounting block 301 on the drum 3 is inserted into the mounting groove 208 on the mounting plate 205. Then, the bolt 10 is threaded through the first threaded hole 209 and the second threaded hole 302 in sequence to fix the mounting plate 205 and the mounting block 301. Thus, drums 3 of different sizes can be installed and fixed according to production needs.

[0033] When it is necessary to disassemble the drum 3, start the electric push rod 8 to move the arc plate 9 to the bottom of the drum 3. Then, remove the bolt 10 from the mounting plate 205 and the mounting block 301. After that, reverse the handle 207 to drive the bidirectional threaded rod 202 to rotate, so that the two fixing plates 204 move away from each other and the mounting plate 205 is removed from the mounting block 301. At this time, the drum 3 will fall on the arc plate 9, and the disassembly is completed.

[0034] Please refer to this carefully. Figure 2 The upper surface of the base 1 is provided with a first sliding groove 101. A sliding rod 6 is fixed to the inner wall of the first sliding groove 101. A slider 7 is slidably connected to the outer surface of the sliding rod 6. The upper surface of the slider 7 is fixed to the bottom surface of the fixed plate 204, which can guide and support the movement of the fixed plate 204.

[0035] Please refer to this carefully. Figure 5 Two mounting plates 4 are fixed on the upper surface of the base 1. Two guide rollers 5 are rotatably connected to the side of the two mounting plates 4 that are close to each other. The two guide rollers 5 are arranged in an up-down manner. The up-down distribution structure can effectively limit the film between the two guide rollers 5.

[0036] In use, the present invention involves placing the drum 3 onto the arc-shaped plate 9, then activating the electric push rod 8 to move the arc-shaped plate 9. The arc-shaped plate 9 moves the drum 3 between the two mounting discs 205. Once the drum 3 is positioned between the two mounting discs 205, rotating the handle 207 rotates the bidirectional threaded rod 202. The rotation of the bidirectional threaded rod 202 causes the two threaded blocks 203 to move closer together. The threaded blocks 203 move the fixing plate 204, which in turn moves the mounting discs 205. This allows the mounting block 301 on the roll 3 to be inserted into the mounting groove 208 on the mounting plate 205. Then, the bolt 10 is threaded through the first threaded hole 209 and the second threaded hole 302 in sequence to fix the mounting plate 205 and the mounting block 301. This allows rolls 3 of different sizes to be installed and fixed according to production needs. Then, one end of the film is passed between the two guide rollers 5 and installed on the roll 3. Then, the rotary motor 206 is started, which drives the roll 3 to rotate through the mounting plate 205 to wind up the film.
