Description

Technical Field

[0001] The invention belongs to the technical field of PVC film production, in particular to a flattening device for a PVC film calender. Background Art

[0002] PVC film, full name is film, the main component is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. After the PVC film is produced by the calender, a flattening device will be used to flatten the PVC film, and the winding equipment will be used to roll it up and pack it.

[0003] A patent with publication number CN216548860U discloses a flattening device for a PVC film calender. The patent uses an adsorption seat, adsorption holes, a negative pressure component and a power component to achieve adsorption of the PVC film by the negative pressure generated by the negative pressure component near the adsorption holes on the adsorption seat when the PVC film passes through the device. At the same time, the two adsorption seats are driven away from each other by the power component. When the rubber roller on the fixed seat rubs against the PVC film, the PVC film can be flattened by moving the adsorption seat, thereby avoiding the flattening work only by increasing the tension of the PVC film, thereby protecting the PVC film.

[0004] In the above-mentioned prior art, when flattening the produced PVC film, the PVC film is flattened by adsorption and pulling it to move to both sides. However, some parts of the PVC film that are wrinkled and stuck together due to residual heat are difficult to unfold. At the same time, it may also cause the PVC film to tear easily during the pulling process due to the different forces between the wrinkled and sticky parts and the flat parts. In addition, in the process of flattening the PVC film, it is inconvenient to quickly cool it down, resulting in residual temperature of the PVC film, which causes sticking or folding during the flattening process.

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0033] See also Figure 1-8 , the present invention provides a technical solution:

[0034] A flattening device for a PVC film calender comprises a base 1, a first fixing frame 2 is symmetrically fixedly connected to one side of the upper end of the base 1, an auxiliary roller 6 is slidably connected between the inner cavities of the two first fixing frames 2, a support frame 7 is symmetrically fixedly connected to the middle of the upper end of the base 1, a cross fixing plate 8 is commonly fixedly connected to the upper ends of the two support frames 7, a transmission groove 9 is arranged in the middle of the upper end of the cross fixing plate 8, and a film anti-wrinkle beating component is arranged in the inner cavity of the transmission groove 9;

[0035] The film anti-wrinkle beating assembly includes two U-shaped rotating blocks 31 rotatably connected in the inner cavity of the transmission groove 9, the two U-shaped rotating blocks 31 are fixedly connected with round blocks 30 on their surfaces close to each other, the outer part of the round block 30 is fixedly connected with a driven bevel gear 41, the driven bevel gear 41 is meshingly connected with the transmission bevel gear 29, the inner cavity of the U-shaped rotating block 31 is rotatably connected with a pull rod 33, the end of the pull rod 33 away from the U-shaped rotating block 31 is rotatably connected to a fixed block 34, and the lower end of the fixed block 34 is fixedly connected with a beating plate 14.

[0036] Specifically, in the prior art, when flattening the produced PVC film, the PVC film is pulled to move to both sides by adsorption to achieve flattening, but some parts of the PVC film that are wrinkled and stuck together by residual heat are difficult to unfold, and it is also easy to tear during the pulling process due to the different forces between the wrinkled and flat parts of the PVC film;

[0037] When flattening the produced PVC film, the present invention places the produced PVC film on the top of the auxiliary roller 6, and then passes the PVC film through the film anti-wrinkle flapping components to connect with the external winding device, and then uses the external winding device to pull the PVC film for mobile winding. During the winding process of the PVC film, the driving bevel gear 29 is driven to rotate, and at the same time, the driving bevel gear 29 meshes with the driven bevel gear 41 to rotate, thereby driving the round block 30 to rotate. During the rotation of the round block 30, the round block 30 can be used to drive the two U-shaped rotating blocks 31 to rotate synchronously, and at the same time, the transmission rod 33 of the U-shaped rotating block 31 makes an up and down reciprocating motion, and during the up and down reciprocating motion of the rod 33, the fixed block 34 is driven to move synchronously, thereby making the fixed block 34 The block 34 drives the beating plate 14 to slide and move synchronously in the inner cavity of the support frame 7, so that the beating plate 14 beats the PVC film below it to prevent the produced PVC film from folding or sticking together, thereby solving the problem that the flattening device of the existing PVC film calender utilizes adsorption to pull the PVC film to move to both sides for unfolding and flattening, resulting in some parts of the PVC film that are wrinkled and stuck together due to residual heat. It is difficult to unfold them by adsorption and pulling. At the same time, forcibly pulling the PVC film to flatten it will also cause the PVC film to tear during the pulling process due to different forces on the wrinkled and sticky parts and the flat parts of the PVC film. It is also inconvenient to flatten the produced PVC film during the winding process, thereby affecting the processing efficiency of the PVC film.

[0038] like Figure 1 to Figure 2 As shown, a first fixed column 3 is fixedly connected to the inner cavity of the first fixed frame 2, a slider 5 is slidably connected to the outside of the first fixed column 3, a first spring 4 is fixedly connected to the bottom of the inner cavity of the first fixed frame 2, one end of the first spring 4 away from the bottom of the inner cavity of the first fixed frame 2 is fixedly connected to the slider 5, and an auxiliary roller 6 is slidably connected to the slider 5.

[0039] Specifically, in the process of winding the PVC film, the slider 5 is moved upward by utilizing the first spring 4, and the slider 5 slides upward outside the first fixed column 3, and then the slider 5 drives the auxiliary roller 6 to move synchronously, so that the auxiliary roller 6 can be used to lift the newly produced PVC film. In the process of lifting the PVC film by the auxiliary roller 6, the external winding equipment is cooperated to increase the tension of the PVC film, so as to avoid the PVC film from wrinkling or sticking during the transportation of the auxiliary roller 6.

[0040] like Figures 1 to 5 As shown, a second fixed column 11 is fixedly connected to the inner cavity of the support frame 7, a support plate 13 is slidably connected to the outside of the second fixed column 11, a slapping plate 14 is slidably connected to the outside of the second fixed column 11, a second spring 12 is fixedly connected to the upper and lower walls of the inner cavity of the support frame 7, one end of the second spring 12 away from the upper and lower walls of the inner cavity of the support frame 7 is fixedly connected to the support plate 13 and the slapping plate 14, and rubber pads are provided on the surfaces close to each other of the support plate 13 and the slapping plate 14.

[0041] Specifically, when the produced PVC film is flattened, the flapping plate 14 is driven to slide outside the second fixed column 11 to make up and down reciprocating motions, and at the same time, the second spring 12 in the inner cavity of the support frame 7 bounces up the support plate 13 and moves upward, so that the support plate 13 lifts the PVC film between the support plate 13 and the flapping plate 14, and then the flapping plate 14 is driven to slide outside the second fixed column 11 to make up and down reciprocating motions, and the flapping plate 14 cooperates with the support plate 13 to flap the PVC film, thereby achieving the unfolding effect on the PVC film, thereby preventing the newly produced PVC film from folding or sticking together during the traction and winding process.

[0042] like Figures 1 to 5 As shown, a driving motor 27 is disposed inside one end of the cross fixing plate 8 , and the driving motor 27 is fixedly connected to a cylinder 28 via an output shaft, and an end of the cylinder 28 away from the driving motor 27 is fixedly connected to a transmission bevel gear 29 .

[0043] Specifically, when the PVC film is pulled and wound by the winding equipment, the cylinder 28 is driven to rotate by the output shaft of the driving motor 27, and at the same time, the cylinder 28 drives the transmission bevel gear 29 to rotate, and then the transmission bevel gear 29 drives the film anti-wrinkle flapping component to operate, and then the film anti-wrinkle flapping component is used to unfold the PVC film, so as to avoid the newly produced PVC film from folding or sticking together during the pulling and winding process, thereby improving the flattening efficiency of the PVC film. Example

[0044] like Figures 1 to 8 As shown in Comparative Example 1, another embodiment of the present invention is:

[0045] like Figure 1 , Figure 5 and Figure 8 As shown, auxiliary flattening components are provided on both sides of the lower end of the cross fixing plate 8, and the auxiliary flattening components include air guide tubes 16 fixedly connected to both sides of the lower end of the cross fixing plate 8, and one end of the air guide tube 16 away from the cross fixing plate 8 is fixedly connected to a bellows 15, and dustproof mesh covers 10 are installed inside both sides of the upper end of the cross fixing plate 8, and an arc-shaped electric heating air guide plate 38 is fixedly connected to the inner cavity of the bellows 15.

[0046] Specifically, when the PVC film is pulled and rolled by the rolling device, the air guide tube 16 is driven to draw the external air into its inner cavity, and then the air is discharged into the inner cavity of the bellows 15 by the air guide tube 16, and at the same time, the arc-shaped electric heating air guide plate 38 in the inner cavity of the bellows 15 is used to block the air discharged from the inner cavity of the air guide tube 16, so that the air diffuses to both ends in the inner cavity of the bellows 15, thereby ensuring that the air can be evenly discharged from the inner cavity of the bellows 15, and the arc-shaped electric heating air guide plate 38 located at the auxiliary roller 6 will not be turned on for heating, so that the bellows 15 The exhausted air is cold air, so that the newly produced PVC film can be quickly cooled down to avoid residual heat in the PVC film, which may cause sticking or folding during the beating and flattening process. After the beating and flattening is completed, the air is heated by the arc-shaped electric heating air guide plate 38 in the inner cavity of the bellows 15, and then the heated air is evenly discharged through the bellows 15 and blown to the PVC film, so that the PVC film can be slightly softened, thereby improving the winding efficiency and preventing the PVC film from being too hard and tearing during the winding process.

[0047] like Figure 1 , Figure 5 and Figure 8 As shown, the end of the U-shaped rotating block 31 away from the round block 30 is fixedly connected to a support column 32, the end of the support column 32 away from the U-shaped rotating block 31 passes through the cross fixing plate 8, and the end located in the inner cavity of the cross fixing plate 8 is fixedly connected to a second bevel gear 42, and the support column 32 is rotatably connected to the cross fixing plate 8.

[0048] Specifically, when the PVC film is pulled and rolled by the rolling equipment, the round block 30 is driven to rotate, which in turn drives the U-shaped rotating block 31 to rotate. At the same time, the U-shaped rotating block 31 drives the support column 32 to rotate, and then the support column 32 drives the second bevel gear 42 to rotate. Then, the second bevel gear 42 drives the auxiliary flattening component to blow and cool the newly produced PVC film, thereby improving the flattening efficiency of the PVC film.

[0049] like Figure 1 , Figure 5 and Figure 8 As shown, the second bevel gear 42 is meshedly connected with the first bevel gear 40 , the first bevel gear 40 has a second rotating column 39 fixedly connected inside, the second rotating column 39 has a plurality of impellers 43 fixedly connected outside, and the second rotating column 39 is rotatably connected to the dustproof net cover 10 .

[0050] Specifically, when the PVC film is pulled and wound by the winding equipment, the second bevel gear 42 is driven to rotate, and at the same time, the second bevel gear 42 meshes with the first bevel gear 40 to rotate, thereby driving the second rotating column 39 to rotate. During the rotation of the second rotating column 39, the multiple impellers 43 are driven to rotate, so that the multiple impellers 43 draw external air into the inner cavity of the air guide tube 16 through the dustproof mesh cover 10, and then use the dustproof mesh cover 10 to filter the internal dust of the drawn air, so as to avoid the situation where the dust affects the appearance of the PVC film when the PVC film is blown to cool it down, thereby causing the quality of the PVC film to decline.

[0051] like Figure 1 , Figure 2 and Figure 7 As shown, an auxiliary winding assembly is provided on one side of the upper end of the base 1, and the auxiliary collecting assembly includes a second fixed frame 17 fixedly connected to one side of the upper end of the base 1, and slide grooves 18 are provided at both ends of the second fixed frame 17. A bidirectional threaded rod 19 is rotatably connected to the inner cavity of the slide groove 18, and the external thread of the bidirectional threaded rod 19 is connected to the first support block 22 and the second support block 23, and the first support block 22 and the second support block 23 are rotatably connected to the first clamping roller 20 and the second clamping roller 21 close to each other, and the first clamping roller 20 and the second clamping roller 21 are both provided with a latex protective layer on the outside.

[0052] Specifically, in the process of winding the PVC film, the bidirectional threaded rod 19 is driven to rotate, and at the same time, the bidirectional threaded rod 19 threadedly drives the first support block 22 and the second support block 23 to slide in the inner cavity of the slide groove 18 and move close to each other. In the process of the first support block 22 and the second support block 23 moving close to each other, the first clamping roller 20 and the second clamping roller 21 are driven to move synchronously, and then the first clamping roller 20 and the second clamping roller 21 can use the external latex protective layer to clamp and shape the PVC film, thereby avoiding wrinkles in the process of winding the PVC film.

[0053] like Figure 1 , Figure 2 and Figure 6 As shown, a protective cover 24 is fixedly connected to one side of the upper end of the base 1, and a transmission shaft 25 is rotatably connected to the inner cavity of the protective cover 24.

A first rotating column 37 is fixed to the inside of the worm 36, and a crank 26 is fixed to the end of the first rotating column 37 away from the worm 36.

[0054] Specifically, during the process of winding the PVC film, the crank handle 26 is driven to rotate, which in turn drives the first rotating column 37 to rotate, and drives the worm 36 to rotate, thereby causing the worm 36 to engage the transmission worm wheel 35 to rotate. During the rotation of the worm wheel 35, the transmission shaft 25 is driven to rotate by the worm wheel 35, and the transmission shaft 25 is used to drive the auxiliary winding assembly to adjust the spacing, so that the auxiliary winding assembly can clamp and shape the PVC film to avoid wrinkles during the winding process of the PVC film.

[0055] like Figure 1 , Figure 6 and Figure 7 As shown, both ends of the transmission shaft 25 pass through the second fixing frame 17 , and a transmission gear 44 is fixedly connected to one end of the inner cavity of the second fixing frame 17 .

[0057] Working principle: when flattening the produced PVC film, the produced PVC film is placed on the top of the auxiliary roller 6, and then the PVC film is passed through the film anti-wrinkle flapping components and connected to the external winding device, and then the external winding device is used to pull the PVC film for moving and winding. During the winding process of the PVC film, the transmission bevel gear 29 is driven to rotate, and at the same time, the transmission bevel gear 29 meshes with the transmission driven bevel gear 41 to rotate, and then the round block 30 is driven to rotate.

[0058] During the process of the PVC film being pulled and rolled by the rolling device, the air guide tube 16 is driven to draw the external air into its inner cavity, and then the air is discharged into the inner cavity of the bellows 15 by the air guide tube 16, and at the same time, the arc-shaped electric heating air guide plate 38 in the inner cavity of the bellows 15 is used to block the air discharged from the inner cavity of the air guide tube 16, so that the air diffuses to both ends in the inner cavity of the bellows 15, thereby ensuring that the air can be evenly discharged from the inner cavity of the bellows 15, and the arc-shaped electric heating air guide plate 38 located at the auxiliary roller 6 will not be turned on for heating, so that the air discharged from the bellows 15 is The air discharged is cold air, so that the newly produced PVC film can be quickly cooled down to avoid residual heat in the PVC film, which may cause sticking or folding during the beating and flattening process. After the beating and flattening is completed, the air is heated by the arc-shaped electric heating air guide plate 38 in the inner cavity of the bellows 15, and then the heated air is evenly discharged through the bellows 15 and blown to the PVC film, so that the PVC film can be slightly softened, the winding efficiency is improved, and the PVC film is prevented from being too hard and torn during the winding process.

[0059] During the winding process of the PVC film, the crank handle 26 is driven to rotate, and the first rotating column 37 is driven to rotate, and the worm 36 is driven to rotate, and then the worm 36 is meshed with the transmission worm wheel 35 to rotate. During the rotation of the worm wheel 35, the transmission shaft 25 is driven to rotate by the worm wheel 35, and the transmission shaft 25 is used to drive the transmission gear 44 to rotate, and then the transmission gear 44 is meshed with the transmission driven gear 45 to rotate, and then the driven gear 45 is used to drive the bidirectional threaded rod 19 to rotate, so that the bidirectional threaded rod 19 threadedly drives the first support block 22 and the second support block 23 to slide in the inner cavity of the slide groove 18 and move close to each other. During the movement of the first support block 22 and the second support block 23 close to each other, the first clamping roller 20 and the second clamping roller 21 are driven to move synchronously, and then the first clamping roller 20 and the second clamping roller 21 can use the external latex protective layer to clamp and shape the PVC film to avoid wrinkles during the winding process of the PVC film.
