Description

Technical Field

[0001] This utility model belongs to the field of SPC flooring processing machinery, specifically relating to a guide device for an SPC flooring bonding and soundproofing pad machine. Background Technology

[0002] SPC flooring (Stone Plastic Composite) is a new type of environmentally friendly flooring. It is a composite board made of stone powder and thermoplastic polymer materials that are mixed evenly and then extruded at high temperature. It combines natural stone powder and polymer materials, and has the properties and characteristics of both wood and plastic. It is wear-resistant, waterproof and has strong stability.

[0003] In recent years, the production of SPC flooring in the flooring industry has been increasing year by year. Because SPC flooring does not require glue during installation, it is environmentally friendly and has been well-received by users. However, uneven ground and humidity changes during installation can cause the flooring to deform after a period of use, affecting its usability or causing noise. Therefore, current technology incorporates sound-absorbing pads on the back of SPC flooring to prevent noise caused by deformation during use. These pads also reduce deformation caused by humidity, making the flooring more aesthetically pleasing and usable.

[0004] For ease of processing, sound-absorbing mats are generally processed in roll form. During production, the machines used to bond the sound-absorbing mats to SPC flooring use pressing rollers or bonding rollers to attach the mats to the back of the flooring substrate. During the roll material's journey, factors such as uneven winding in previous processes, guide roller deviation, vibration, and strip tension fluctuations can cause the strip to deviate from its original reference position, affecting processing efficiency and yield, and resulting in energy and material waste. Therefore, guiding or correction devices are needed to ensure the high-speed, normal, and stable operation of automated production lines. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing SPC flooring sound-absorbing mat bonding machines lack guiding or correction devices. Therefore, this invention provides a guiding device for SPC flooring sound-absorbing mat bonding machines.

[0006] To achieve the above objectives, the present invention proposes the following technical solution:

[0007] A guiding device for an SPC floor bonding and sound-absorbing mat machine includes a first support, a second support, a guide roller, and a tensioning device. The first support is disposed beside the second support, and the second support is disposed on a base. A support shaft is disposed on the first support. The guide roller is disposed on the second support. The tensioning device includes a tensioning movable rod located below the guide roller. The opposite ends of the tensioning movable rod are slidably connected to the second support, allowing the tensioning movable rod to reciprocate along a direction close to or away from the guide roller. The tensioning movable rod, the guide roller, and the support shaft are axially parallel.

[0008] Specifically, the first bracket can fix the support shaft, which includes an installation component and an unwinding component. The installation component can be connected and fixed to the first bracket, and the unwinding component is used to install and fix the roll material while being connected to the motor as an unwinding roller to transport the silent pad roll to the second bracket.

[0009] Specifically, the second support can be equipped with multiple guide rollers, which can be located at the top, bottom, and areas between the top and bottom ends of the second support. Different guide rollers are used depending on the material and size of the roll. To cooperate with the tensioning device, the second support has at least two guide rollers for fixing and guiding the sound-absorbing pad roll at both ends of the tensioning device. The initial position of the tensioning movable rod is located below the limiting rod. To ensure sufficient vertical movement of the tensioning movable rod, at least two guide rollers are positioned above its initial position. Guide rollers can also be positioned below the initial position of the tensioning movable rod, mainly for correcting the direction of the sound-absorbing pad before it passes through the tensioning device and enters the pressing device.

[0010] Specifically, during the lamination process, the sound-absorbing pad roll is fed from the support shaft, passes through several guide rollers, and is finally laminated. During this process, it may become too tight, causing elastic elongation or loosening deformation, or the roll material may be conveyed inefficiently due to insufficient tension. The tensioning device can maintain constant tension of the sound-absorbing pad during the transportation and processing, improve the conveying efficiency, and prevent the sound-absorbing pad from deviating or sagging, ensuring accurate delivery of the roll material.

[0011] Furthermore, the tensioning device also includes an upper limiting module and / or a lower limiting module, wherein the upper limiting module is disposed at the upper end of the second bracket and the lower limiting module is disposed at the lower end of the second bracket.

[0012] Specifically, the upper limit module and the lower limit module can be sensing probes, photoelectric switches or proximity switches, mainly used to detect the range of motion of the tensioning rod in real time, and connected to the machine's power unit. They can be remotely controlled through preset specific signals to adjust the unwinding speed of the silent pad according to the range of motion of the tensioning rod.

[0013] Depending on the size of the roll material and processing requirements, both the upper and lower limit modules can function independently. They can sense the distance between the tensioning rod and the upper limit module to control the movement of the roll material on the support shaft, or they can achieve the same function through the lower limit module. This adapts to different roll material sizes, especially large-area roll materials, and improves processing efficiency and precision.

[0014] Furthermore, one or both ends of the tensioning movable rod are fixedly provided with limit sensor plates, which correspond to the upper limit module and / or the lower limit module.

[0015] Specifically, the limit sensor can be used in conjunction with the limit module to facilitate the limit module's sensing of the movement range of the tensioning rod. Limit sensors are installed at one or both ends of the tensioning rod, moving up and down with it. The limit module determines the distance between the tensioning rod and the limit module by detecting the position of the limit sensors. To facilitate distance sensing by the limit module, the limit sensors are typically positioned on the same vertical line as the limit module.

[0016] Furthermore, the second bracket is symmetrically provided with limiting and fixing rods, and the opposite ends of the tensioning movable rod are respectively slidably connected to the limiting and fixing rods, so that the tensioning movable rod can reciprocate along the axial direction of the limiting and fixing rods.

[0017] Specifically, the tensioning movable rod is slidably mounted on two symmetrically arranged limiting and fixing rods, and the limiting module can be installed on the limiting and fixing rods or in an adjacent position.

[0018] Furthermore, the tensioning movable rod is provided with sliding members at both ends, and the sliding members are slidably disposed on the limiting fixed rod, thereby driving the tensioning movable rod to reciprocate along the axial direction of the limiting fixed rod.

[0019] Specifically, the tensioning rod has sliding parts at both ends. The sliding parts include, but are not limited to, a slider assembly that can slide up and down on the limit fixing rod, a mechanical part that can slide up and down along the limit fixing rod by adjusting the tension with screws, and an assembly that connects the tensioning rod and the limit fixing rod respectively.

[0020] Furthermore, a movable component is installed at the lower end of the first bracket, and the movable component includes casters.

[0021] Specifically, casters and other easily movable components are installed under the first support, allowing for adjustment of the distance between the first and second supports according to the size and properties of the rolled material. Types of casters include, but are not limited to, movable casters, fixed casters, and movable casters with brakes.

[0022] Furthermore, the first bracket is provided with at least one positioning hole, and the support shaft is fixed to the first bracket through the positioning hole.

[0023] Specifically, positioning holes at different positions can be used according to the size of the roll material and actual processing requirements. The support shaft can be installed on the bracket through the positioning holes. Alternatively, multiple support shafts can be installed as needed, and different roll materials can be installed on them. Multiple guide rollers on the second bracket can be used to achieve simultaneous bonding and processing of multiple roll materials.

[0024] Furthermore, a limiting structure is provided on the support shaft, the limiting structure including a surface protrusion structure or an annular limiting device.

[0025] Specifically, in order to prevent the silent pad roll from shifting position due to mechanical vibration, frictional stress and other factors during the unwinding process, a limiting structure is set on the support shaft. For example, a protruding structure is designed on the surface of the support shaft or a ring-shaped limiting device is installed to fix the position of the silent pad roll and prevent axial displacement during processing.

[0026] Furthermore, the guiding device also includes a pressing guide roller, which is separately disposed on the base.

[0027] Specifically, the sound-absorbing pad is conveyed by the guide device and then leads to the bottom of the pressing roller for bonding. The pressing guide roller prevents the sound-absorbing pad from shifting during bonding. The pressing guide roller is separately separated and installed on the base. It is mainly used to correct the deviation of the sound-absorbing pad before bonding. The specific position can be adjusted according to the properties and size of the roll material.

[0028] Furthermore, at least one pair of correction components are symmetrically arranged on the pressing guide roller, and the correction components include axial baffles or limiting rings with adjustable distance.

[0029] Specifically, the alignment component is used to limit the movement or offset of the sound-absorbing pad. The type of alignment component can be selected according to actual needs, including but not limited to axial baffles or limiting rings symmetrically arranged on the roller body. The axial baffles or limiting rings are perpendicular to the radial direction of the guide roller. The distance between the axial baffles or limiting rings is adjusted and fixed according to the width of the sound-absorbing pad to prevent the sound-absorbing pad from wrinkling, offsetting or other problems during transportation.

[0030] Two pairs of limiting baffles are set to different sizes, which can simultaneously correct the deviation of the sound-absorbing pad roll and the board before and after the bonding process. Since the width of the sound-absorbing pad is usually smaller than the width of the board, the small baffle set on the inner side can adjust the distance according to the width of the sound-absorbing pad, and the large baffle set on the outer side can adjust the distance according to the width of the board. This allows for simultaneous correction of the sound-absorbing pad and the board during bonding. It can also be used for situations where the board size and the roll size are inconsistent, or for situations where the roll is modified in a specific area of ​​the board.

[0031] The processing machine for bonding sound-absorbing pads to SPC flooring provided by this utility model also includes a hopper, a pressing device, a conveying device, and an edge-trimming device. The hopper is located at the inlet end of the conveying device and is used to place the board to be bonded with the sound-absorbing pad. The conveying device is located at the outlet end of the hopper and is used to convey the board to the bottom of the pressing device. The pressing device bonds the sound-absorbing pad to the back of the board body. The edge-trimming device is located at the outlet end of the pressing device and is used to trim and cut off the excess sound-absorbing pad at both ends of the board to obtain SPC flooring with the sound-absorbing pad bonded.

[0032] The beneficial effects of this utility model are:

[0033] (1) This utility model effectively prevents problems such as wrinkles and misalignment that may occur during the bonding process of sound-absorbing pads and boards by setting a guiding device on the sound-absorbing pad bonding machine, which greatly improves processing efficiency and optimizes yield and accuracy. Specifically, by setting a tensioning device in the guiding device, which works in conjunction with the guide roller, the sound-absorbing pad maintains constant tension during the transportation and processing, which improves the conveying efficiency. At the same time, it achieves the purpose of preventing the sound-absorbing pad from deviating or sagging and ensuring accurate delivery of the roll material. The tensioning device works in conjunction with the limit sensing module to achieve the integrated effect of the tensioning system and the unwinding system, which simplifies the processing technology.

[0034] (2) By setting multiple positioning holes and support shafts on the first bracket, this utility model works in conjunction with the guide device to achieve the purpose of flexibly adjusting each component of the guide device according to the material and size of the roll material, and realizes the technical purpose of simultaneous bonding processing of multiple roll materials, which greatly improves the processing efficiency. It is suitable for bonding processing of roll materials of various sizes. Combined with the tensioning device, it can greatly improve the accuracy of large-size roll material processing.

[0035] (3) By setting up a pressing guide roller, this utility model achieves precise correction of both the soundproof pad and the board. The synergistic effect of the above components can achieve better limit correction effect, greatly improve processing efficiency and accuracy, reduce defect rate, and realize automated feeding processing.

[0045] See attached document Figure 1 This utility model provides a machine for bonding sound-absorbing mats to SPC flooring, specifically including: a machine base 1, a guiding device, a pressing device, and a conveying device, which are sequentially arranged on the machine base 1.

[0046] The machine 1 is equipped with a motor that provides power to the guiding device and the conveying device, which respectively controls the rotation of the support shaft to feed the material and the rotation of the conveying roller to transport the material.

[0047] The pressing device includes pressing rollers 6 mounted on a base and pressing power devices 61 fixedly connected to the pressing rollers 6. The pressing power devices 61 consist of a pair of symmetrically arranged cylinders, which are connected and fixed to each other by pressing roller fixing rods 62.

[0048] The area where the sound-absorbing pad is actually bonded by the pressing roller 6 is designated as a finishing area, covered with a special yellow material. This material is used to mark the processing area of ​​the sound-absorbing pad and to adjust the material of the special material according to the material of the sound-absorbing pad, preventing damage to the sound-absorbing pad during the pressing process. Multiple pressing rollers can be set as needed to enhance the bonding effect, or multiple sets of cylinders can be set simultaneously to provide power to the pressing device.

[0049] The conveying device includes multiple axially parallel conveyor rollers, which are fixed in position and flush at the top. Driven by a power unit, they rotate radially in the same direction and at the same speed, conveying the sheet material in a specific direction through frictional stress. Depending on the needs of conveying the sheet material, a conveyor belt can be laid on the conveyor rollers to prevent friction between the rollers and the sheet material during conveying, thus preventing damage to the appearance of the sheet material.

[0050] The present invention provides a guide device for an SPC floor bonding sound-absorbing mat machine, comprising a first bracket 3 and a second bracket 4. The first bracket 3 is disposed beside the second bracket, and the second bracket 4 is disposed on a base 2. The first bracket 3 is provided with a first support shaft 32 and a second support shaft 33, and a sound-absorbing mat roll 34 is disposed on the first support shaft 32. The first bracket 3 is also provided with a plurality of positioning holes 31 for mounting and fixing the support shaft. The lower end of the first bracket 3 is provided with a universal wheel with a foot brake, and the first support shaft 32 is provided with an adjustable limiting structure, specifically a surface protrusion structure.

[0051] The second support 4 is equipped with guide rollers and a tensioning device. The guide rollers include a first guide roller 41, a second guide roller 42 and a third guide roller 43 at the upper end of the second support 4, a fourth guide roller 44 at the middle end and a fifth guide roller 45 at the lower end. The guide rollers provided on the second support 4 are not limited to the above positions and quantities, and can be added or removed according to actual needs.

[0052] The tensioning device includes a tensioning movable rod 52, an upper limiting module 53, and a lower limiting module 54. The tensioning movable rod 52 is slidably disposed on the limiting fixed rod 51 and located between the symmetrically arranged limiting fixed rods 51. The limiting fixed rods 51 are symmetrically arranged on the second bracket 44. The initial position of the tensioning movable rod 52 is located below the first guide roller 41, the second guide roller 42, the third guide roller 43, and the fourth guide roller 44.

[0053] The upper limit module 53 and the lower limit module 54 are respectively installed at the upper and lower ends of the second bracket 4, near the limit fixing rod 51 and located radially outside the axis of the limit fixing rod 51.

[0054] As attached Figure 2 As shown, a sliding member 55 is provided on the limiting and fixing rod 51, and the sliding member 55 can move up and down along the axial direction of the limiting and fixing rod 51; the sliding member 55 and the tensioning movable rod 52 are connected and fixed by a connector. A limiting sensor 56 is fixedly provided on the sliding member 55, and the limiting sensor 56 and the limiting module are arranged coaxially along the axial direction of the limiting and fixing rod 51.

[0055] The limit modules that can be used in this embodiment include the BEN5M-MDT photoelectric sensor, the CDLJ-18A3-8-Z / BX proximity switch, and the BR100-DDT photoelectric switch. The material of the limit sensing sheet matches the model of the limit module used, namely the light absorber for BEN5M-MDT, the metal sheet for CDLJ-18A3-8-Z / BX, and the plastic sheet for BR100-DDT.

[0056] The pressing guide roller 57 is set separately on the base 2. The pressing guide roller 57 is equipped with at least one pair of correction components. The correction components can be mechanically fixed to the roller body by setting T-slot guide rails or linear slide rails on the guide roller body, and the position can be adjusted by the guide rails or slide rails. Alternatively, screw holes can be set on the correction components, and the position of the correction components can be fixed and moved by installing screws.

[0057] The axial directions of the aforementioned support shaft, guide roller, tensioning rod 52, pressing guide roller 57, and pressing wheel 6 are all kept parallel.

[0058] The aforementioned machine also includes a hopper and an edge trimming device. Both the hopper and the edge trimming device are based on mature technologies and will not be described in detail in this embodiment.

[0059] The working principle of the processing machine for bonding sound-absorbing pads to SPC flooring provided by this utility model is as follows:

[0060] Set the first bracket 3 at an appropriate position next to the machine base 1 or the base 2, install and fix the first support shaft 32 and the second support shaft 33 in the positioning hole, and install the silent pad roll 34 to be processed on the first support shaft 32.

[0061] The first support shaft 32 is used as the main support shaft and the second support shaft 33 is used as the auxiliary support shaft. The first support shaft 32 rotates and unwinds under the control of the power device. The second support shaft 33 presses against the surface of the sound-absorbing pad roll by adjusting its spatial position to prevent displacement when the amount of roll material is too large. As the amount of roll material gradually decreases during the processing, a new sound-absorbing pad roll can be installed on the second support shaft 33. After the aforementioned roll material processing is completed, the processing of a new roll material can begin as soon as possible to improve processing efficiency.

[0062] The second bracket 4 is placed on the base 2, the pressing device is placed on the rear side of the second bracket 4, and the pressing guide roller 57 is installed and fixed on the base in front of the pressing wheel 6. The axial direction of the pressing guide roller 57 and the pressing wheel 6 is adjusted to be parallel to the guide roller on the second bracket 4.

[0063] The initial end of the silent pad roll 34 is pulled out from the upper side of the first support shaft 32, passes around the first guide roller 41, passes from the lower side through the tensioning movable rod 52, passes upward through the second guide roller 42, then passes downward through the fourth guide roller 44, and finally is attached to the lower side of the pressing wheel 6 via the pressing guide roller 57, coinciding with the finishing area.

[0064] The guide rollers used can be adjusted according to actual needs. For example, the initial end of the silent pad roll 34 can be pulled out from the upper side of the first support shaft 32, passed around the first guide roller 41, passed through the tensioning movable rod 52 from the lower side, passed up the third guide roller 43, then passed down the fifth guide roller 45, and finally adhered to the lower side of the pressing wheel 6 via the pressing guide roller 57, coinciding with the finishing area.

[0065] The front end of the conveying device is connected to a hopper. The sheet material is placed on the conveying device and transported towards the guide device. The top plane of the conveying device is flush with the upper surface of the base 2. The sheet material is transported to the base 2 by the conveying device and passes under the pressing guide roller 57 and pressing wheel 6 in sequence, while being located under the silent pad.

[0066] When the machine starts, the tensioning device controls the first support shaft 32 to release the material, while the pressing wheel 6 presses down and rotates. During the processing, the initial end of the silent pad starts from the support shaft 32, is driven and transported in the guide device, specifically through the guide roller, passes through the tensioning movable rod of the tensioning device 52 from the outside, then through the guide roller, and finally through the pressing wheel 6 for bonding processing. As the bonding process progresses, the tension on the sound-absorbing pad, which is being transported in the guiding device, gradually increases. The tensioning rod 52 moves upwards due to the increased force. At this point, the lower limit module 54 detects that the distance between the tensioning rod 52 and the lower limit module 54 exceeds a preset range. Therefore, it controls the support shaft 32 to begin rotating and feeding material to prevent the sound-absorbing pad from stretching or deforming due to excessive tension. As the support shaft 32 feeds material, the tension on the sound-absorbing pad gradually decreases, and the pad adhering to the outside of the tensioning rod 52 gradually relaxes. The tensioning rod 52 loses its force and naturally falls back to the lower end. The lower limit module 54 detects that the distance between the tensioning rod 52 and the lower limit module 54 has reached the preset range. Therefore, it controls the support shaft 32 to stop feeding material to prevent the sound-absorbing pad from relaxing or shifting due to insufficient tension.

[0067] The sound-absorbing pad and the board are pressed by the pressing guide roller 57 and the pressing roller 6 to attach the sound-absorbing pad to the surface of the board transported by the conveying device. The board with the sound-absorbing pad attached leaves the pressing device through the conveying device set at the exit end of the guide device. The excess sound-absorbing pad at both ends of the board is cut off by the edge trimming device to obtain the SPC floor with the sound-absorbing pad attached.

[0068] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.

[0069] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
