Description

Technical Field

[0001] The utility model relates to the technical field of fiberglass mat processing, in particular to a rewinder for fiberglass mats. Background Technique

[0002] A fiberglass mat is a thin sheet product made by randomly combining continuous or chopped rovings together through chemical binders or mechanical action. It can be used in various aspects such as sound insulation, fire prevention, and shock absorption, and has a wide range of applications in the fields of construction, automobiles, and hygiene. During its production process, rewinding equipment is required to trim and rewind the fiberglass mat.

[0003] The existing fiberglass mat rewinding equipment has the following drawbacks when in use: during the rewinding process of the existing fiberglass mat, it is generally directly cut by a cutting knife and then directly rewound. Since the fiberglass mat is usually thin and the connection is not tight enough, it is very easy to have lateral pulling and tearing during the cutting process, affecting the integrity of the fiberglass mat. For this reason, we propose a rewinder for fiberglass mats. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a rewinder for fiberglass mats. Through the setting of a rectifying and pressing mechanism inside the machine body, it can rectify and press the side end of the fiberglass mat when it is about to approach the cutting position, improve the side tightness, and reduce the phenomenon of transverse pulling of the cut during the cutting process, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A rewinder for fiberglass mats includes a machine body and also includes a rectifying and pressing mechanism. The rectifying and pressing mechanism is arranged inside the machine body. The rectifying and pressing mechanism includes a fixed roller, a fixed ring, a support plate, a mounting frame, a pressing roller, and a spring. The fixed roller is horizontally installed inside the machine body and the fixed ring is sleeved on the outer periphery of the fixed roller. A support plate is arranged at the bottom position of the fixed roller inside the machine body. The bottom of the fixed ring is movably connected to the mounting frame through a spring, and the pressing roller that fits to the top of the support plate is installed inside the mounting frame.

[0007] Further, it further includes an adjusting mechanism. An adjusting mechanism is provided between the machine body and the fixed ring. The adjusting mechanism includes a mounting hole, a screw hole, and a screw rod. A mounting hole is horizontally opened on one side inside the fixed ring. Screw holes are opened at corresponding positions on both sides inside the machine body, and screw rods are movably connected through the screw holes. The ends of the screw rods penetrate into the mounting hole; the end of the machine body is connected to a screw rod through the screw hole, and the end of the screw rod penetrates into the mounting hole and is connected to the fixed ring. Before the cutting operation, turn the screw rod along the screw hole. During the turning process of the screw rod, it can drive the fixed ring to horizontally move along the outer circumference of the fixed roller, thereby adjusting its position so that the pressing position is exactly on the side of the cutting position of the cutting knife.

[0008] Further, a rewinding roller for winding the fiberglass mat is installed on one side inside the machine body, and a cutting knife is installed inside the machine body; the rewinding roller winds the cut fiberglass mat, and the cutting knife performs the edge cutting treatment.

[0009] Further, limiting grooves are vertically opened at the bottom end inside the fixed ring, and limiting rods fixedly connected to the top of the mounting frame and passing through springs and inserted into the limiting grooves; through the cooperation of the limiting grooves and the limiting rods, the pressing roller can only maintain a downward pressure.

[0010] Further, end rings are installed on the outer circumference of the screw rod and the end rings are attached to both sides of the surface of the fixed ring; the end ring structure fixes the connection between the end of the screw rod and the fixed ring, so that the fixed ring can be driven to move when the screw rod is turned.

[0011] Compared with the prior art, the present utility model has the following beneficial effects: The edge of the fiberglass mat is cut by the cutting knife inside the machine body and wound by the rewinding roller. Before cutting, the positions of the cutting knife and the pressing roller are adjusted so that the end of the pressing roller is aligned with the side of the cutting knife towards the center position of the frame. During the conveying process of the fiberglass mat, it passes between the top of the support plate and the pressing roller. The downward pressure of the pressing roller is maintained by the elastic force of the spring, and the side of the fiberglass mat that does not need to be cut is compacted, improving the compactness of the side of the fiberglass mat. During the cutting process of the cutting knife, since the uncut side of the fiberglass mat is compacted, the horizontal pulling of the cut can be avoided, and the problem of damage to the side of the fiberglass mat can be avoided, maintaining the flatness of the cut; the end of the machine body is connected to a screw rod through the screw hole, and the end of the screw rod penetrates into the mounting hole and is connected to the fixed ring. Before the cutting operation, turn the screw rod along the screw hole. During the turning process of the screw rod, it can drive the fixed ring to horizontally move along the outer circumference of the fixed roller, thereby adjusting its position so that the pressing position is exactly on the side of the cutting position of the cutting knife.

Specific embodiments

[0016] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] As Figures 1-3 shown, a rewinder for a glass fiber mat includes a machine body 1 and further includes a pressing mechanism 2. The pressing mechanism 2 is arranged inside the machine body 1. The pressing mechanism 2 includes a fixed roller 203, a fixed ring 204, a support plate 205, a mounting bracket 206, a pressing roller 207 and a spring 208. The fixed roller 203 is horizontally installed inside the machine body 1 and the fixed ring 204 is sleeved on the outer periphery of the fixed roller 203. The support plate 205 is arranged at the bottom position of the fixed roller 203 inside the machine body 1. The bottom of the fixed ring 204 is movably connected with the mounting bracket 206 through the spring 208 and the pressing roller 207 attached to the top of the support plate 205 is installed inside the mounting bracket 206.

[0018] Among them, it further includes an adjusting mechanism 3. An adjusting mechanism 3 is arranged between the machine body 1 and the fixed ring 204. The adjusting mechanism 3 includes a mounting hole 301, a screw hole 302 and a screw 303. A mounting hole 301 is horizontally opened on one side inside the fixed ring 204. Screw holes 302 are opened at corresponding positions on both sides inside the machine body 1 and the screw 303 is movably connected through the screw holes 302. The ends of the screw 303 all penetrate inside the mounting hole 301; the end of the machine body 1 is connected with the screw 303 through the screw hole 302, and the end of the screw 303 penetrates inside the mounting hole 301 and is connected with the fixed ring 204. Before the cutting operation, turn the screw 303 along the screw hole 302. During the turning process of the screw 303, the fixed ring 204 can be driven to horizontally move along the outer periphery of the fixed roller 203, thereby adjusting its position so that the pressing position is exactly on the side of the cutting position of the cutting knife 202.

[0019] Among them, a rewinding roller 201 for winding the fiberglass mat is installed on one side inside the machine body 1. A cutting knife 202 is installed inside the machine body 1. Limiting grooves 209 are vertically formed at the bottom ends inside the fixing ring 204. Limiting rods 210 that penetrate through the spring 208 and are inserted into the limiting grooves 209 are fixedly connected to the tops of the mounting frames 206. The rewinding roller 201 winds the cut-edge fiberglass mat, and the cutting knife 202 performs the edge-cutting process. Through the cooperation of the limiting groove 209 and the limiting rod 210, the pressing roller 207 can only maintain a downward pressure.

[0020] Among them, end rings 304 are installed on the outer periphery of the screw rod 303, and the end rings 304 are attached to both sides of the surface of the fixing ring 204. The structure of the end rings 304 fixes the end of the screw rod 303 and the fixing ring 204 together, so that the fixing ring 204 can be driven to move when the screw rod 303 is rotated.

[0021] It should be noted that the present invention is a rewinder for fiberglass mats. When in use, the inside of the machine body 1 performs edge-cutting treatment on the fiberglass mat through the cutting knife 202 and winds it through the rewinding roller 201. Before cutting, adjust the positions of the cutting knife 202 and the pressing roller 207 so that the end of the pressing roller 207 is aligned with the side of the cutting knife 202 on the side closer to the center of the frame. During the conveying process of the fiberglass mat, it passes between the top of the support plate 205 and the pressing roller 207. The elastic force of the spring 208 is used to maintain the downward pressure of the pressing roller 207, and the uncut position on the side of the fiberglass mat is compacted, improving the tightness of the side of the fiberglass mat. During the cutting process of the cutting knife 202, since the uncut position on the side of the fiberglass mat is compacted, the transverse pulling of the cut can be avoided, and the problem of damage to the side of the fiberglass mat can be avoided, maintaining the flatness of the cut. One end of the machine body 1 is connected to a screw rod 303 through a screw hole 302. The end of the screw rod 303 penetrates through the inside of the mounting hole 301 and is connected to the fixing ring 204. Before the cutting operation, turn the screw rod 303 along the screw hole 302. During the turning process of the screw rod 303, the fixing ring 204 can be driven to horizontally move along the outer periphery of the fixing roller 203, thereby adjusting its position so that the flattening position is exactly on the side of the cutting position of the cutting knife 202.
