Description

Technical Field

[0001] This utility model belongs to the field of SPC flooring processing machinery, specifically relating to a conveying device for a machine for bonding sound-absorbing SPC flooring. 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. Due to the need for automated processing, both the sound-absorbing mat rolls and the boards are typically handled by automated feeding or transport equipment. During the journey of the roll material, factors such as uneven winding in the previous process, guide roller deviation, vibration, and strip tension fluctuations can cause the strip material to deviate from its original reference position. Similarly, during transport, the boards may experience slight positional and directional shifts due to mechanical vibration, uneven stress, and the influence of the sound-absorbing mats during bonding. Even slight deviations in either the roll material or the boards during transport can affect processing efficiency and yield, resulting in wasted energy and materials. Therefore, it is necessary to install a conveyor correction device for the boards to ensure the high-speed, normal, and stable operation of the automated production line. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing processing machines for bonding SPC (Silicone Polymer) flooring mats lack a correction device. Therefore, this invention provides a conveying device for a machine that bonds SPC flooring mats.

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

[0007] A conveying device for a machine for bonding sound-absorbing SPC flooring includes a conveying support, conveying rollers, and a conveying correction device. The conveying rollers are disposed inside the conveying support and include multiple axially parallel conveying rollers. The conveying correction device includes a guide rail and a limiting member. The guide rail is symmetrically laid on the upper surface of the conveying rollers and is parallel to the transport direction of the conveying rollers. The limiting member is connected and fixed to the guide rail.

[0008] Specifically, the conveyor rollers include multiple conveyor rollers arranged on the same plane and parallel to each other axially. They are driven by a power unit to rotate radially in the same direction and at the same speed. The sheet material is placed on the upper surface of the conveyor rollers, and the conveyor rollers transport the sheet material in a specific direction by rotating.

[0009] Specifically, guide rails are symmetrically arranged on the upper end face of the conveyor rollers. The axial direction of the rails is parallel to the conveyor rollers' material transport direction. The distance between the rails can be adjusted according to the width of the transported material. To avoid the material being hindered by friction during transport, the distance between the rails is slightly larger than the width of the material.

[0010] To prevent the guide rail and the sheet material from shifting during the operation of the conveyor rollers and to further fix the distance between the guide rails, a horizontal bar-like limiting component, i.e., a limiting bar, is installed on the guide rail. The limiting component can be mounted and fixed on the upper end face of the guide rail, or a hollow structure cavity can be set in the guide rail for installing and fixing the limiting component.

[0011] To enhance the fixing effect, one or more limiting components can be set.

[0012] Furthermore, both ends of the limiting member are respectively connected and fixed to the conveying bracket, and simultaneously connected and fixed to the symmetrically arranged guide rails, with the axial direction of the limiting member being perpendicular to the axial direction of the guide rails.

[0013] Specifically, the limiting member is basically parallel to the axial direction of the conveying roller and perpendicular to the guide rail which is parallel to the transport direction of the conveying roller. In order to further enhance the fixing function of the guide rail position, the limiting member and the guide rail form a cross structure for fixing, and the two ends of the limiting member are respectively connected and fixed to the conveying bracket.

[0014] Furthermore, the guide rail has an installation groove parallel to its axial direction, and the limiting member has a through groove parallel to its axial direction. By simultaneously installing fasteners in the installation groove and the through groove, the limiting member is fixed on the guide rail.

[0015] Specifically, the limiting crossbar has a through-type groove along the axial direction, and the guide rail has a mounting groove with a groove structure along the axial direction. The screws can be moved and adjusted in the groove. The fasteners are installed as a whole through the through-type groove and the mounting groove, fixing the limiting crossbar to the guide rail and locking the distance between the guide rails. As the size of the sheet metal changes, the position of the limiting crossbar and the distance between the guide rails can be adjusted accordingly.

[0016] Fasteners include, but are not limited to, integrated screws, snap fasteners, or magnetic fasteners.

[0017] Furthermore, both ends of the conveying roller are fixedly mounted on the conveying bracket, and the conveying bracket is provided with a correction groove or a correction hole. At least one end of the conveying roller is connected and fixed to the conveying bracket through the correction groove or the correction hole.

[0018] Specifically, the conveyor support has correction grooves or correction holes on one or both sides corresponding to the positions of the conveyor rollers. One end of the conveyor roller is fixed to a specific position on the machine through the correction grooves or correction holes. By adjusting the position of the conveyor roller installed in the mounting groove, the correction offset angle of the conveyor roller relative to the axial direction of the conveyor roller is adjusted. The direction of the correction groove is parallel to the axial direction of the conveyor support.

[0019] Furthermore, the conveying roller is offset clockwise or counterclockwise along the axial direction, and the offset range is 5°-10°.

[0020] Specifically, to ensure transportation stability and facilitate the alignment of the panel and the sound-absorbing pad, a guide rail fixed on one side is designated as the reference rail. The edge of the panel is placed close to the inside of the reference rail and transported by the conveyor rollers below, serving a positioning function while reducing transmission resistance. Frictional stress is generated between the panel edge and the inside of the rail during movement, while the other edge of the panel is not in close contact with the rail, resulting in uneven stress on both sides. During transport, the side of the panel that is in contact with the reference rail experiences a slight lag, meaning that the panel has a slight angular offset when transported to the base and cannot accurately conform to the sound-absorbing pad.

[0021] To adjust the angle of the board, the conveyor rollers are offset clockwise or counterclockwise along the plane axis to ensure that the board's orientation is consistent with the orientation of the sound-absorbing pad, so that the sound-absorbing pad can accurately fit the designated area of ​​the board.

[0022] The specific offset angle of the drive roller can be adjusted within the range of 5°-10° according to the material and friction coefficient of the board, so as to balance the frictional lag and angular offset generated during the transportation of the board and maintain a constant speed and constant direction during the transportation process.

[0023] Furthermore, the conveying device also includes at least one conveying guide roller; the conveying guide roller is disposed on the conveying support.

[0024] Specifically, when the conveying device transports the boards, the un-laminated boards are transported to the laminating device via conveyor rollers for lamination. Before lamination, the boards are corrected by conveyor guide rollers. These guide rollers correct the orientation of the boards, preventing them from shifting during their passage from the conveying device to the laminating device and affecting the lamination effect. The conveyor guide rollers can be disassembled and installed separately, and can be installed in appropriate positions according to the board specifications.

[0025] Furthermore, at least one pair of correction components are symmetrically arranged on the conveying guide roller, and the correction components include axial baffles or limiting rings with adjustable distance.

[0026] 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.

[0027] 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.

[0028] Furthermore, the conveying bracket is provided with a base, and the base is symmetrically provided with limiting pads.

[0029] Specifically, the conveyor transports the sheet material to the base, where a pressing device mounted on the base performs the bonding process. To further correct any misalignment of the sheet material before and after bonding, limiting blocks are installed on the base. These limiting blocks consist of a pair of symmetrically arranged protruding components mounted on the base. They are used to fix the position of the sheet material before bonding, during bonding, and after bonding, preventing misalignment and facilitating the transport of the bonded sound-absorbing pad sheet material outside the machine, thus achieving automated processing and transportation. The spacing between the symmetrically arranged limiting blocks is adapted to the size of the sheet material.

[0030] To ensure the corrective effect, one or more limit pads can be set.

[0031] Furthermore, the base is also provided with a limiting groove or a limiting hole, and the limiting pad is installed and fixed to the base through the limiting groove or the limiting hole.

[0032] Specifically, the base is equipped with limiting grooves or limiting holes, allowing the limiting pads to be installed in appropriate positions according to the dimensions of the sheet material. The limiting grooves facilitate the adjustment of the limiting pad positions. The direction of the limiting grooves is parallel to the direction of movement of the limiting pads.

[0033] Furthermore, the limiting pad has a through-type horizontal groove, and the limiting pad is fixed on the base by installing fasteners in both the limiting groove or the limiting hole and the through-type horizontal groove.

[0034] Specifically, a through-type transverse groove is provided on the limiting pad, which can accommodate plates of different sizes. The distance between the limiting pads can be finely adjusted according to actual needs. Fasteners are installed integrally through the transverse groove on the through-type pad and the limiting groove or limiting hole on the base, fixing the limiting pads to the base. The distance between the limiting pads is adjusted by adjusting the position of the fasteners in the groove. The direction of the through-type transverse groove is parallel to the moving direction of the limiting pad and perpendicular to the transport direction of the plate.

[0035] Fasteners include, but are not limited to, integrated screws, snap fasteners, or magnetic fasteners.

[0036] The processing machine for bonding sound-absorbing mats to SPC flooring provided by this utility model also includes a machine base, a sound-absorbing mat unwinding device, a hopper, a pressing device, and an edge-trimming device. A power unit can be placed inside the machine base, which can serve as a drive device for multiple components of the machine, such as driving the conveyor device. The sound-absorbing mat unwinding device is located next to the pressing device and is used to unwind the sound-absorbing mat roll. The pressing device is used to bond the sound-absorbing mat and the board. The hopper is located at the inlet end of the conveyor device and is used to hold the board to be bonded with the sound-absorbing mat. 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 mat at both ends of the board.

[0037] The beneficial effects of this utility model are:

[0038] (1) By setting a correction device on the soundproofing pad application machine, this utility model effectively prevents the deviation problem that may occur when the soundproofing pad and the board are bonded and processed and when the board is transported. The correction device works in conjunction with the conveyor roller to keep the board at a constant speed and constant direction during transport, which greatly improves the processing efficiency and optimizes the yield and accuracy.

[0039] (2) By setting up a conveying guide roller, a conveying correction device, and a limiting pad that can be detached and installed separately, the present invention achieves precise correction of both the soundproof pad and the board material simultaneously through the coordinated action of the above components, resulting in a better limiting correction effect, greatly improving processing efficiency and accuracy, reducing defect rate, and realizing automated feeding processing.

[0051] See attached document Figure 1 This utility model provides a machine for bonding sound-absorbing SPC flooring, specifically including: a machine base 1, a guiding device, a pressing device, and a conveying device, with the conveying device mounted on the machine base 1.

[0052] 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.

[0053] The guiding device includes a first bracket 3 and a second bracket 4. The first bracket 3 is provided with a first support shaft 32 and a second support shaft 33. A sound-silencing pad roll 34 is provided 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.

[0054] The second support 4 is provided with guide rollers, including 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 and a fifth guide roller 45 at the middle end and a sixth guide roller 46 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.

[0055] The pressing device includes a pressing wheel 6 and a pressing power device 61 fixedly connected to the pressing wheel 6. The pressing power device 61 consists of a pair of symmetrically arranged cylinders, which are connected and fixed by a pressing wheel fixing rod 62.

[0056] 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 according to the material of the sound-absorbing pad, preventing damage to the pad during the pressing process. Multiple pressing rollers can be installed as needed to enhance the bonding effect, and multiple sets of cylinders can be used to power the pressing device.

[0057] The conveying device for the SPC flooring bonding machine provided by this utility model includes a conveying support, a conveying roller 71, a guide rail 72, and a limiting member 73. The conveying roller 71 includes multiple axially parallel conveying rollers arranged inside the symmetrically arranged conveying support. The guide rail 72 is laid on the conveying roller 71 and is parallel to the transport direction of the conveying roller 71. The limiting member 73 is vertically mounted on the guide rail 72, and both ends of the limiting member 73 are fixedly installed on the two end faces of the conveying support.

[0058] As attached Figure 2 As shown, the guide rail 72 has an installation groove parallel to the axial direction, and the limiting member 73 has a through groove parallel to its axial direction. By installing an integrated screw in the installation groove and the through groove, the limiting member 73 is installed and fixed on the guide rail 72.

[0059] To facilitate the adjustment of the position of the limiting component 73, limiting grooves parallel to the axial direction of the guide rail 72 can be set on the upper end face of both sides of the conveyor bracket. The two ends of the limiting component 73 are installed in the limiting grooves on both sides of the machine tool by screws. The position of the limiting component 73 can be adjusted by adjusting the position of the screws in the limiting grooves of the machine tool and the position of the integrated screws in the mounting grooves of the guide rail 72.

[0060] To facilitate adjustment of the crossbar position and track distance, a knob head is provided on the top of the integrated screw to enhance manual turning operability.

[0061] To enhance the positioning effect of the limiting component, the two ends of the limiting component 73 can be fixed to both sides of the conveyor bracket by means of mechanical connection with bolts and nuts, quick-release buckles or clamps, etc. When the position of the limiting component 73 relative to the guide rail 72 changes, the position of its connection and fixation to the conveyor bracket also changes accordingly.

[0062] As attached Figure 3As shown, the conveyor roller consists of two connecting shafts at both ends connecting the roller body and the roller body. One end of the connecting shaft is fixed to the conveyor support using a connector, and the other end is fixed to the conveyor support using a bearing. A correction groove is provided on the upper surface of one side of the conveyor support, corresponding to the position of the conveyor roller. A screw, passing through the threaded hole of the connector and the correction groove, fixes one end of the conveyor roller to a specific position on the conveyor support. By adjusting the position of the screw within the correction groove, the correction offset angle of the connector and the conveyor roller fixed to the connector relative to the axial direction of the conveyor roller can be adjusted. A knob head is provided on the top of the screw to enhance manual turning operability.

[0063] When transporting sheet metal, one side of the guide rail is used as the reference rail. If the left guide rail is used as the reference rail, the conveying rollers will be offset counterclockwise by 5°-10° along the axial direction plane. If the right guide rail is used as the reference rail, the conveying rollers will be offset clockwise by 5°-10° along the axial direction plane.

[0064] As attached Figure 4 As shown, a base 2 is provided on the conveyor support. Limiting pads 21 and limiting holes 22 are symmetrically arranged on the base 2. A through-type horizontal groove is opened on each limiting pad 21. The limiting pad 21 is installed and fixed on the base 2 by installing an integrated screw in the limiting hole 22 and the through-type horizontal groove. The spacing of the symmetrical limiting pads 21 can be adjusted according to the width of the plate through the through-type horizontal groove and the limiting hole 22.

[0065] To facilitate adjustment of the spacing between the limit pads, a knob head is provided on the top of the integrated screw to enhance manual turning operability.

[0066] The conveying guide roller 5 is set separately on the conveying support, specifically at the front end of the pressing device. The conveying guide roller 5 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.

[0067] The axial directions of the aforementioned guide roller, conveying guide roller 5, and pressing roller 6 are all kept parallel.

[0068] 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.

[0069] The working principle of the processing machine for bonding sound-absorbing pads to SPC flooring provided by this utility model is as follows:

[0070] The first bracket 3 is set on the side of the machine base 1 or the base 2. The first support shaft 32 and the second support shaft 33 are installed and fixed in the positioning hole. The silent pad roll 34 to be processed is installed on the first support shaft 32.

[0071] The second bracket 4 is placed on the base 2, the pressing device is placed behind the second bracket 4, and the conveying guide roller 5 is installed and fixed on the base at the inlet end of the pressing wheel 6. The axial direction of the conveying guide roller 5 and the pressing wheel 6 is adjusted to be parallel to the guide roller on the second bracket 4.

[0072] 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 fifth guide roller 45, passes upward through the second guide roller 42, and finally adheres to the lower side of the pressing roller 6 via the conveying guide roller 5, coinciding with the finishing area.

[0073] 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, then passed through the fourth guide roller 44 from the lower side, passed up through the third guide roller 43, then passed down through the sixth guide roller 46, and finally adhered to the lower side of the pressing roller 6 via the conveying guide roller 5, coinciding with the finishing area.

[0074] The front end of the conveying device is connected to a hopper. The sheet metal is close to the left reference track of the guide rail 72 and is transported towards the guide device by multiple conveying rollers 71. Two limiting parts 73 are installed on the guide rail 72 for fixing. The conveying rollers 71 are offset counterclockwise by 5°-10° along the axial plane. The specific offset angle can be set according to the actual situation, including but not limited to 6°, 7°, 8°, 9°, etc., to balance the offset caused by uneven force on both sides of the sheet metal.

[0075] The top surface of the conveyor roller 71 is flush with the upper surface of the base 2. The plate is transported to the base 2 by the conveyor roller 71, and passes under the conveyor guide roller 5 and the pressing roller 6 in sequence, while located under the silent pad.

[0076] When the machine starts, the first support shaft 32 feeds the material, and at the same time the pressing roller 6 presses down and rotates to attach the sound-absorbing pad to the surface of the board material transported by the conveying roller 71. During the bonding process, the board material is fixed in position by the limiting pad 21. After bonding is completed, the board material leaves the pressing device through the limiting pad 21 and the conveying device. The excess sound-absorbing pad at both ends of the board material is cut off by the edge trimming device to obtain the SPC flooring with the sound-absorbing pad.

[0077] 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.

[0078] 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. Technical details not described in detail in this utility model can all be implemented by any existing technology in the art. In particular, all technical features not described in detail in this utility model can be implemented by any existing technology.
