Description

Technical Field

[0001] This utility model relates to the technical field of coating machine accessories, and in particular to a winding rack for a coating machine. Background Technology

[0002] A coating machine is a device used to apply thermoplastic materials with specific properties to substrates such as paper, aluminum foil, and plastic film. The material coated on the substrate is dried and hardened to improve the substrate's sealing, barrier, anti-reflective, insulation, and strength properties. The substrate roll is fed into the coating machine, and the coating head evenly coats the substrate surface with adhesives, paints, or inks. Then, the coating is dried and cured by a drying device, and finally, the coating is wound up by a winding device.

[0003] Chinese patent CN216836307U discloses a winding mechanism for a coating machine and the coating machine itself. The winding mechanism of the coating machine includes a winding roller. A buffer plate is provided in front of each of the left and right ends of the winding roller. The tops of the two buffer plates respectively block the left and right ends of the winding roller, and their middle parts are movably connected to the middle of the support platform via springs. Their bottoms are hinged to the bottom of the support platform. As the winding roller rolls down along the guide plate, it pushes against the two buffer plates, causing the two buffer plates to rotate downwards after overcoming the elastic force of the two springs. The two springs provide an upward elastic buffer force to the winding roller through the two buffer plates. This buffer force makes the acceleration of the winding roller rolling down along the guide plate small, so the speed of the winding roller when it rolls to the ground is also relatively small. After that, the winding roller rolls forward at a small speed, and the bearings will not be damaged due to collision.

[0004] To address the aforementioned issues, existing patents have provided solutions. However, in the prior art, when the take-up roller is being wound, it is usually necessary to drive it through gears or friction. In order to ensure stable winding, it is necessary to align the bearing bracket and bolt holes and disassemble and reassemble the roller with bolts, which is inefficient.

[0005] To address this, a take-up frame for a coating machine is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a take-up frame for a coating machine, which can solve the problem that existing take-up rollers usually need to be driven by gears or friction during the take-up operation. In order to ensure the stability of the take-up, it is necessary to align the bearing frame and bolt holes and disassemble and install them with bolts, which is inefficient.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a take-up frame for a coating machine, comprising a coating machine body and a main frame, wherein a reduction motor is fixedly connected to the rear side of the main frame, a guide rail is fixedly connected to the bottom of the main frame, a connecting component is provided at the top of the guide rail and the output end of the reduction motor, and a take-up roller is provided on the outer side of the connecting component;

[0008] The connecting assembly includes an inner roller with an integrally formed mating protrusion on its outer side. A fixed electric cylinder is fixedly connected to the inner side of the inner roller, and a force-bearing frame is fixedly connected to the telescopic end of the fixed electric cylinder. A sliding sleeve is slidably connected to the outer side of the inner roller, and the side of the sliding sleeve closest to the force-bearing frame is fixedly connected to the force-bearing frame. A short frame is rotatably connected to the outer side of both the sliding sleeve and the mating protrusion. A clamping frame is rotatably connected to the side of the short frame away from the inner roller, and a key is fixedly connected to the outer side of the clamping frame. The outer side of the key engages with the take-up roller.

[0009] Preferably, the take-up roller includes a hollow roller and a limiting piece sleeved on the outside of the hollow roller, and a mating key for use with a key is fixedly connected to the inside of the hollow roller.

[0010] Preferably, a rotating block is fixedly connected to the outer side of both the mating protrusion and the sliding sleeve, and the inner side of the rotating block is rotatably connected to the short frame.

[0011] Preferably, a slider is slidably connected to the inner side of the guide rail, a bracket is fixedly connected to the top of the slider, and the inner side of the bracket is rotatably connected to the right inner roller.

[0012] Preferably, a lead screw is rotatably connected to the inner side of the guide rail, a control motor is externally connected to the right side of the guide rail, the output end of the control motor passes through the guide rail and is fixedly connected to the lead screw, and the outer side of the lead screw is threadedly connected to the slider.

[0013] Preferably, a base is fixedly connected to the bottom of the main frame, a cylinder is installed on the top of the base, and a loading and unloading frame is fixedly connected to the telescopic end of the cylinder, the loading and unloading frame being located at the bottom of the hollow roller.

[0014] Preferably, a sub-frame is fixedly connected to the right side of the main frame, a guide roller is rotatably connected to the inner side of the sub-frame, the left side of the guide roller is rotatably connected to the inner side of the main frame, and control electric cylinders are fixedly connected to the inner side of the sub-frame and the left side of the inner side of the main frame. A tension roller is installed on the inner side of the telescopic end of the control electric cylinder.

[0015] Preferably, a slide bar is slidably connected to the inner side of the card holder, and a limiting telescopic plate is fixedly connected to the side of the slide bar near the inner roller. The limiting telescopic plate is fixedly connected to the inner roller on the side near the inner roller.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This application uses a main frame to support the structure, and a geared motor to drive the left connecting assembly to rotate. When the take-up roller needs to be installed, it can be placed directly outside the left connecting assembly, and the right connecting assembly can be moved along the guide rail so that the two sides of the inner side of the take-up roller are respectively located outside the two inner rollers. Then, the force-bearing frame can be pushed and pulled along the fixed electric cylinder. The force-bearing frame will push the adjacent sliding sleeve to move. At this time, the short frame outside the sliding sleeve will push the clamp away from the inner roller. When multiple clamps open at the same time, they will contact the inner wall of the take-up roller and press against its interior. Driven by the geared motor, the take-up frame will be driven to rotate. When disassembly is required, the extension of the fixed electric cylinder can also make the clamp and key no longer press against the inner wall of the take-up roller, so as to facilitate the replacement of the take-up roller. This avoids the need to align the bearing seat and gear, as well as the process of fixing with bolts, which not only saves labor but also effectively improves work efficiency.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A take-up rack for a coating machine includes a coating machine body 1 and a main frame 2. A reduction motor 3 is fixedly connected to the rear side of the main frame 2, and a guide rail 4 is fixedly connected to the bottom of the main frame 2. A connecting component 5 is provided on the top of the guide rail 4 and the output end of the reduction motor 3. A take-up roller 6 is provided on the outside of the connecting component 5.

[0027] The connecting assembly 5 includes an inner roller 51. The outer side of the inner roller 51 is provided with an integrally formed mating protrusion. A fixed electric cylinder 52 is fixedly connected to the inner side of the inner roller 51. A force-bearing frame 53 is fixedly connected to the telescopic end of the fixed electric cylinder 52. A sliding sleeve 54 is slidably connected to the outer side of the inner roller 51. The side of the sliding sleeve 54 closest to the force-bearing frame 53 is fixedly connected to the force-bearing frame 53. A short frame 55 is rotatably connected to the outer side of both the sliding sleeve 54 and the mating protrusion. A clamping frame 56 is rotatably connected to the side of the short frame 55 away from the inner roller 51. A key 57 is fixedly connected to the outer side of the clamping frame 56. The outer side of the key 57 is engaged with the take-up roller 6.

[0028] In this embodiment: the main frame 2 supports the structure, and the geared motor 3 drives the left connecting assembly 5 to rotate. When the take-up roller 6 needs to be installed, it can be placed directly outside the left connecting assembly 5, and the right connecting assembly 5 is moved along the guide rail 4 so that the two sides of the inner side of the take-up roller 6 are respectively located outside the two inner rollers 51. Then, the force-bearing frame 53 can be pushed and pulled along the fixed electric cylinder 52. The force-bearing frame 53 will push the adjacent sliding sleeve 54 to move. At this time, the short frame 55 outside the sliding sleeve 54 will... Pushing the card holder 56 away from the inner roller 51, when multiple card holders 56 open simultaneously, they will contact the inner wall of the take-up roller 6 and press against its interior. Driven by the geared motor 3, the take-up holder will rotate. When disassembly is required, the extension of the fixed electric cylinder 52 can prevent the card holder 56 and the key 57 from pressing against the inner wall of the take-up roller 6, so as to facilitate the replacement of the take-up roller 6. This avoids the need to align the bearing seat and gears and fix them with bolts, which not only saves labor but also effectively improves work efficiency.

[0029] Specifically, such as Figure 3As shown, the take-up roller 6 includes a hollow roller 61 and a limiting piece 62 sleeved on the outside of the hollow roller 61. A mating key 63 that works with the key 57 is fixedly connected to the inside of the hollow roller 61.

[0030] Specifically, such as Figure 4 As shown, rotating blocks 7 are fixedly connected to the outer sides of the protrusion and the sliding sleeve 54, and the inner side of the rotating blocks 7 is rotatably connected to the short frame 55.

[0031] Specifically, such as Figure 1 As shown, a slider 9 is slidably connected to the inner side of the guide rail 4, and a bracket 10 is fixedly connected to the top of the slider 9. The inner side of the bracket 10 and the right inner roller 51 are rotatably connected.

[0032] In this embodiment: a limiting piece 62 is provided to restrict the position of the wound film material on both sides. The outer part of the hollow roller 61 is used for winding material, and its interior is connected by a mating key 63 and a key 57. When the holder 56 is opened, the key 57 can be inserted into the gap of the mating key 63 to fix the relative position of the structure, which facilitates the transmission of the structure. The rotating block 7 is provided to connect the sliding sleeve 54, the inner roller 51 and the short frame 55, and to give them a certain rotation space. The slider 9 is provided to cooperate with the bracket 10 to facilitate the support of the inner roller 51 on the right side and allow it to rotate. When the left connecting component 5 is driven to rotate, the winding roller 6 will also rotate. When rotating, the right connecting component 5 connected to it can rotate along the bracket 10, so that the structure will not get stuck.

[0033] Specifically, such as Figure 1 and Figure 2 As shown, a lead screw 8 is rotatably connected to the inner side of the guide rail 4, and a control motor is externally connected to the right side of the guide rail 4. The output end of the control motor passes through the guide rail 4 and is fixedly connected to the lead screw 8. The outer side of the lead screw 8 is threadedly connected to the slider 9.

[0034] Specifically, such as Figure 1 and Figure 2 As shown, a base is fixedly connected to the bottom of the main frame 2, and a cylinder 11 is installed on the top of the base. A loading and unloading frame 12 is fixedly connected to the telescopic end of the cylinder 11. The loading and unloading frame 12 is located at the bottom of the hollow roller 61.

[0035] In this embodiment: by setting the lead screw 8, when the external drive motor drives the lead screw 8 to rotate, the slider 9 connected to it can slide along the inner side of the guide rail 4 to drive the top structure to move, which makes it easy to pull out or insert the right connecting component 5 from the inner side of the take-up roller 6, so as to facilitate the loading and unloading of the take-up roller 6. By setting the cylinder 11, it is easy to raise or lower the loading and unloading frame 12, so as to pick up the take-up roller 6 or assist in supporting the take-up roller 6 to bear force, so as to facilitate picking and putting.

[0036] Specifically, such as Figure 2 As shown, a sub-frame 13 is fixedly connected to the right side of the main frame 2. A guide roller 14 is rotatably connected to the inner side of the sub-frame 13. The left side of the guide roller 14 is rotatably connected to the inner side of the main frame 2. A control cylinder 15 is fixedly connected to the inner side of the sub-frame 13 and the left side of the inner side of the main frame 2. A tension roller 16 is installed on the inner side of the telescopic end of the control cylinder 15.

[0037] Specifically, such as Figure 5 As shown, a slide bar 17 is slidably connected to the inner side of the card holder 56. A limiting telescopic plate 18 is fixedly connected to the side of the slide bar 17 near the inner roller 51. The limiting telescopic plate 18 is fixedly connected to the inner roller 51 on the side near the inner roller 51.

[0038] In this embodiment: by setting the sub-frame 13 in conjunction with the guide roller 14, the material to be wound can be easily guided. The control electric cylinder 15 can easily push and pull the tension roller 16 to make it move relative to the guide roller 14, and press against the material to adjust the tension. The slide bar 17 slides inside the card holder 56 and is limited by the limiting telescopic plate 18, which can limit the movement of the card holder 56 and prevent it from deflecting or tilting.

[0039] Working principle: Before the winding action, the winding roller 6 is placed outside the left connecting component 5. The external control motor drives the lead screw 8 to rotate, so that the right connecting component 5 moves along the guide rail 4 to the inside of the winding roller 6, respectively, outside the two inner rollers 51. Then, the fixed electric cylinder 52 is operated to push the clamp 56 to open, so that the key 57 is inserted into the gap of the hollow roller 61 and the key 63, and the clamp 56 presses against the inner wall of the hollow roller 61. If necessary, the cylinder 11 is used to drive the loading and unloading frame 12 to assist in lifting. Then, the reduction motor 3 is started to perform the winding operation. At the same time, the tension roller 16 is adjusted by the control electric cylinder 15 to adjust the material tension. Finally, when disassembling, the fixed electric cylinder 52 is operated to make the clamp 56 and the key 57 no longer press against each other. Then, the lead screw 8 is driven to pull out the right connecting component 5. If necessary, the cylinder 11 is used to drive the loading and unloading frame 12 to pick up the winding roller 6 or lift it to assist in bearing the force.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
