A composite device

Abstract

This utility model discloses a composite device. In the composite device of this application, the waste film in the composite film material conveyed on the conveyor line is guided by the second conveyor roller to the waste collection roller for waste collection. When the waste collection roller is in the working state, the second conveyor roller can normally guide the waste film to the waste collection roller for waste collection. When the waste collection roller is in the stopped state, since the second conveyor roller is located on one side of the width direction of the conveyor line, and the axial direction of the second conveyor roller is spaced apart from the axial direction of the first conveyor roller by a first angle, the second conveyor roller can guide the waste film to one side of the width direction of the conveyor line to reduce the impact of the waste film on the composite film material on the conveyor line, so that the entire composite device can continue to work. When the waste collection roller switches from the stopped state to the working state, the operator can rewind the waste film output by the second conveyor roller onto the waste collection roller so that the waste collection roller can continue to collect the waste film.

Description

Technical Field

[0001] This utility model relates to the field of waste discharge technology of composite devices, and in particular to a composite device. Background Technology

[0002] During the membrane lamination process, there are waste membranes that need to be peeled off from the composite membrane. These waste membranes need to be wound onto a waste collection roller for subsequent centralized processing.

[0003] After a certain amount of waste film is wound onto the waste collection roller, it needs to be removed. During the process of the worker removing the wound waste film from the waste collection roller, the waste collection roller is in a stopped state. At this time, the waste collection roller cannot continue to work. If the laminating device continues to work, the waste film generated by the laminating device will be directly piled on the conveyor line, which is easy to get tangled with the laminating film material on the conveyor line. Therefore, when the waste collection roller is stopped, the entire laminating device also needs to be stopped, which affects the working efficiency of the laminating device. Utility Model Content

[0034] The following is for reference. Figures 1 to 5 The composite device of this application will be described in detail.

[0035] refer to Figure 1and Figure 4 The composite device according to an embodiment of the present invention includes a frame 100, a waste collection roller 200, a conveying module 300, and multiple first conveying rollers 400. The multiple first conveying rollers 400 are arranged at intervals along a predetermined direction on the frame 100, and together they form a conveyor line for conveying the composite film material, which includes waste film. The waste collection roller 200 is disposed on the frame 100, parallel to the first conveying rollers 400, and is used to receive waste film. The 200 has a working state and a stopped state; the conveying module 300 is detachably mounted on the frame 100. The conveying module 300 includes a second conveying roller 310 located on one side of the conveying line width direction. The axial direction of the second conveying roller 310 is spaced apart from the axial direction of the first conveying roller 400 by a first angle. The second conveying roller 310 can guide the waste film to the waste collection roller 200 when the waste collection roller 200 is in the working state, and can also guide the waste film to one side of the conveying line width direction when the waste collection roller 200 is in the stopped state.

[0036] For example, such as Figure 1 and Figure 4 As shown, the composite device includes a frame 100, a waste collection roller 200, a conveying module 300, and multiple first conveying rollers 400. The multiple first conveying rollers 400 are distributed at intervals along the front-to-back direction on the frame 100 and together form a conveying line extending from front to back. The conveying line is used to convey the composite film material from front to back. The waste collection roller 200 is located on the upper side of the conveying line. Both the waste collection roller 200 and the first conveying rollers 400 extend along the left-to-right direction. The conveying module 300 includes a second conveying roller 310. The second conveying roller 310 is located on the right side of the conveying line. The axial direction of the second conveying roller 310 is spaced apart from the axial direction of the first conveying roller 400 by a first angle.

[0037] Furthermore, during the operation of the composite device, the conveyor line transports the composite membrane material from front to back. Waste film in the composite membrane material is discharged through the second conveyor roller 310. When the waste collection roller 200 is in working condition, the operator can wind the waste film discharged from the second conveyor roller 310 onto the waste collection roller 200. At this time, the waste collection roller 200 can rotate to normally wind up the waste film. When the waste film wound on the waste collection roller 200 is fully loaded, the waste collection roller 200 switches from working condition to stop condition. When the machine stops rotating, the second conveyor roller 310 guides the waste film to one side of the conveyor line width direction, allowing the operator to remove the waste film wound on the waste collection roller 200. After the waste film wound on the waste collection roller 200 is removed, the operator can rewind the waste film output from the second conveyor roller 310 onto the waste collection roller 200. The waste collection roller 200 can rotate, and at this time, the waste collection roller 200 switches from the stopped state to the working state, and the waste collection roller 200 can normally rewind the waste film.

[0038] It is understood that in the composite device of this application, by setting a second conveying roller 310, which is located on one side of the width direction of the conveying line and whose axial direction is spaced apart from the axial direction of the first conveying roller 400 by a first angle, when the waste collection roller 200 is in working state, the second conveying roller 310 can normally guide the waste film separated from the composite film to the waste collection roller 200. When the waste collection roller 200 is in a stopped state, the second conveying roller 310 can guide the waste film separated from the composite film to one side of the width direction of the conveying line, so as to reduce the impact of the waste film on the composite film on the conveying line. At this time, the operator can normally unload the waste film wound on the waste collection roller 200, and the composite device can still work normally.

[0039] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 The composite device also includes a guide module 500 mounted on the frame 100. The guide module 500 includes a first guide roller 510 and a second guide roller 520. The axial direction of the first guide roller 510 is spaced apart from the axial direction of the first conveying roller 400 by a second angle, which is smaller than the first angle. The axial direction of the second guide roller 520 is spaced apart from the axial direction of the first conveying roller 400 by a third angle, which is smaller than the first angle. The first guide roller 510 is used to guide the waste film in the conveying line to the second conveying roller 310. The second guide roller 520 is used to guide the waste film output from the second conveying roller 310 to the waste collection roller 200.

[0040] It should be noted that, since the axial direction of the second conveying roller 310 is spaced apart from the axial direction of the first conveying roller 400 by a first angle, if the second conveying roller 310 directly receives the waste film separated from the conveyor line, the waste film will fold and stick together during the process of guiding the second conveying roller 310, thereby affecting the normal winding of the waste film by the subsequent waste collection roller 200. Correspondingly, since the waste collection roller 200 is arranged parallel to the first conveying roller 400, and the axial direction of the waste collection roller 200 is also spaced apart from the axial direction of the second conveying roller 310 by a first angle, if the second conveying roller 310 directly conveys the waste film to the waste collection roller 200, the waste film will fold and stick together during the process of conveying from the second conveying roller 310 to the waste collection roller 200, thereby affecting the normal winding of the waste film by the waste collection roller 200.

[0041] It is understood that in the composite device of this application, by setting a first guide roller and a second guide roller, the axial direction of the first guide roller is spaced apart from the axial direction of the first conveying roller 400 by a second angle, and the second angle is smaller than the first angle; the axial direction of the second guide roller is spaced apart from the axial direction of the second conveying roller 310 by a third angle, and the third angle is smaller than the first angle; the first guide roller can guide the waste film separated from the composite film to the second conveying roller 310; the second guide roller can guide the waste film output from the second conveying roller 310 to the waste collection roller 200; the setting of the first guide roller and the second guide roller can realize the deflection of the waste film while reducing the probability of the waste film folding and sticking.

[0042] In a specific embodiment of this utility model, the first angle is 90°, the second angle is 45°, and the third angle is 45°.

[0043] It is understandable that by setting the first angle to 90°, the first conveying roller 400 and the second conveying roller 310 are set perpendicular to each other. When the waste collection roller 200 is in a stopped state, the second conveying roller 310 can better guide the waste film to one side of the conveyor line width direction, so as to reduce the impact of the waste film on the composite film material on the conveyor line.

[0044] It should be noted that the specific value of the first angle can be adjusted by the staff according to the actual situation and is not necessarily limited to 90°. Similarly, the specific values ​​of the second and third angles can be adjusted by the staff according to the actual situation. The specific value of the second angle is not necessarily limited to 45°, as long as the second angle is smaller than the first angle. The specific value of the third angle is not necessarily limited to 45°, as long as the third angle is smaller than the first angle.

[0045] In some embodiments of this utility model, reference is made to Figure 2 The guide module 500 also includes a first mounting frame 530, which includes a base 531 and a mounting rod 532. The base 531 is detachably connected to the frame 100. The mounting rod 532 is adjustable in position along the horizontal direction on the base 531. The first guide roller 510 and the second guide roller 520 are both adjustable in position along the vertical direction on the mounting rod 532.

[0046] Understandably, the operator can adjust the position of the mounting rod 532 in the horizontal direction relative to the base 531 according to actual needs, so as to adjust the position of the first guide rod and the second guide rod in the horizontal direction; the operator can adjust the position of the first guide rod in the vertical direction relative to the mounting rod 532 according to actual needs, and the operator can also adjust the position of the second guide rod in the vertical direction relative to the mounting rod 532 according to actual needs.

[0047] In some embodiments of this utility model, the base 531 is provided with a horizontally extending elongated hole 531a, and the mounting rod 532 passes through the elongated hole 531a and is slidably disposed along the extending direction of the elongated hole 531a.

[0048] For example, such as Figure 2 As shown, the base 531 has a long strip hole 531a extending to the left and right. The lower end of the mounting rod 532 passes through the long strip hole 531a and can slide along the left and right sides of the long strip hole 531a.

[0049] Furthermore, the staff can slide the mounting rod 532 in the left and right directions as needed to adjust the position of the first guide roller and the second guide roller in the left and right directions.

[0050] In some embodiments of this utility model, the first mounting bracket 530 further includes a first connecting seat 533, which includes two first elastic connecting portions 533a and two second elastic connecting portions 533b. A first mounting hole 533c is formed between the two first elastic connecting portions 533a. The mounting rod 532 is slidably inserted into the first mounting hole 533c. The first elastic connecting portions 533a can maintain contact with the mounting rod 532 under their own elastic force. A second mounting hole 533d is formed between the two second elastic connecting portions 533b. The first guide roller 510 is slidably inserted into the second mounting hole 533d. The second elastic connecting portions 533b can maintain contact with the first guide roller 510 under their own elastic force.

[0051] For example, such as Figure 2 and Figure 3 As shown, the first mounting bracket 530 also includes a first connecting seat 533, which includes two first elastic connecting portions 533a and two second elastic connecting portions 533b. The two first elastic connecting portions 533a are distributed in the horizontal direction, and a vertically extending first mounting hole 533c is formed between the two first elastic connecting portions 533a. The mounting rod 532 is slidably inserted into the first mounting hole 533c in the vertical direction. The two second elastic connecting portions 533b are distributed in the vertical direction, and a horizontally extending second mounting hole 533d is formed between the two second elastic connecting portions 533b. The first guide rod is slidably inserted into the second mounting hole 533d in the horizontal direction.

[0052] Understandably, under the elastic force of the first elastic connecting part 533a, the first elastic connecting part 533a is tightly attached to the wall of the mounting rod 532, thereby generating sufficient friction between the first elastic connecting part 533a and the mounting rod 532 to fix the mounting rod 532 in the first mounting hole 533c. When the operator needs to adjust the position of the first connecting seat 533 in the vertical direction, the operator can overcome the friction between the first elastic connecting part 533a and the mounting rod 532 to achieve the vertical position adjustment of the first connecting seat 533. Under the elastic force of the second elastic connecting part 533b, the second elastic connecting part 533b is tightly attached to the wall of the first guide rod, thereby generating sufficient friction between the second elastic connecting part 533b and the first guide rod to fix the first guide rod in the second mounting hole 533d. When the operator needs to adjust the position of the first guide rod in the horizontal direction, the operator can overcome the friction between the second elastic connecting part 533b and the first guide rod to achieve the horizontal position adjustment of the first guide rod.

[0053] In a further embodiment of this utility model, reference is made to... Figure 2 The first mounting bracket 530 also includes a second connecting seat 534, through which the second guide rod is connected to the mounting rod 532.

[0054] Specifically, the structural form of the second connecting seat 534 is the same as that of the first connecting seat 533, and the connection form between the second guide rod, the second connecting seat 534 and the mounting rod 532 is the same as that between the first guide rod, the first connecting seat 533 and the mounting rod 532.

[0055] In some embodiments of this utility model, reference is made to Figure 1 and Figure 5 The composite device also includes a third guide roller 600, which is arranged parallel to the first conveying roller 400 and is used to guide the waste film on the conveying line to the first guide roller 510. The third guide roller 600 is provided with two limiting members 610, which are distributed along the axial direction of the third guide roller 600 and are used to limit the waste film in the axial direction of the third guide roller 600.

[0056] It should be noted that, since there is a second angle between the first guide roller 510 and the first conveying roller 400, when the waste film is peeled off from the composite film material and guided to the first guide roller 510, the waste film will be misaligned in the axial direction of the first conveying roller 400, thereby affecting the composite film material on the conveying line.

[0057] It is understandable that by setting a third guide roller 600, which has two limiting members 610, the two limiting members 610 can limit the waste film in the axial direction of the third guide roller 600, so as to reduce the deviation of the waste film in the axial direction of the first conveying roller 400.

[0058] In some embodiments of this utility model, the conveying module 300 further includes a second mounting frame 320 and a pressing roller 330. The second conveying roller 310 and the pressing roller 330 are rotatably mounted on the second mounting frame 320. The pressing roller 330 is used to press the waste film onto the roller surface of the pressing roller 330. The second mounting frame 320 is detachably connected to the frame 100.

[0059] For example, such as Figure 4 As shown, the conveying module 300 also includes a second mounting frame 320 and a pressing roller 330. The second mounting frame 320 is detachably connected to the frame 100. The pressing roller 330 and the second conveying roller 310 are rotatably mounted on the second mounting frame 320, and the pressing roller 330 and the second conveying roller 310 are arranged in parallel.

[0060] Understandably, the pressing roller 330 is configured to press the waste film onto the second conveying roller 310, thereby reducing the probability of slippage between the second conveying roller 310 and the waste film.

[0061] Understandably, since the second mounting bracket 320 is detachably connected to the frame 100, the operator can install the second mounting bracket 320 at a suitable position on the frame 100 as needed, so as to achieve the installation of the entire conveying module 300 at a suitable position on the frame 100.

[0062] In a further embodiment of this utility model, reference is made to... Figure 4 The conveying module 300 also includes a driver 340, which is mounted on the second mounting bracket 320 and is connected to the second conveying roller 310 for driving the second conveying roller 310 to rotate.

[0063] It is understandable that by placing the driver 340 on the second mounting bracket 320, it is convenient for the driver 340 to drive the second conveyor roller 310 to rotate. On the other hand, the driver 340 can be installed and removed from the frame 100 along with the second mounting bracket 320, so that after the staff installs or removes the second mounting bracket 320, there is no need to install or remove the driver 340, which saves time and effort.

[0064] In some embodiments of this utility model, the composite device further includes a peeling blade (not shown in the figure), which is angle-adjustable and mounted on the frame 100, and is used to peel the waste film from the composite film material.

[0065] Understandably, the design of the peeling blade allows the waste membrane to be easily peeled off from the composite membrane material.

[0066] Understandably, the adjustable peeling blade angle is located on the frame 100, allowing operators to adjust the peeling blade angle according to actual needs to adapt to the peeling of waste film in different types of composite membrane materials.

[0067] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
