Description

Technical Field

[0001] This utility model relates to the technical field of carpet smoothing machines, specifically a multi-blade carpet layering smoothing machine. Background Technology

[0002] As a widely used flooring material in homes, offices, exhibitions, and other areas, the uniformity and high consistency of the carpet's surface pile significantly impact its overall appearance and performance. During carpet production and maintenance, the surface pile typically undergoes finishing treatment to remove defects such as long fibers, burrs, and tangles, thereby improving the carpet's smoothness and aesthetics.

[0003] Currently, most common carpet smoothing equipment uses a single-blade roller rotary cutting structure, which trims the entire carpet surface by setting a single blade roller or a fixed blade head. Some structures use adjustable spacing between the blade roller and the slide plate to control the trimming depth and accommodate carpet layers of different thicknesses. However, the above solutions still have the following significant shortcomings in practical use:

[0004] Poor trimming stability: Due to the use of a single blade structure and the lack of multi-stage buffering or cutting layer adjustment mechanisms, it is easy to cause uneven cutting, trimming breaks or surface damage when cutting carpets at one time.

[0005] Lack of precise control: Existing devices mostly rely on mechanical limits or manual adjustment to adjust the blade head, resulting in low adjustment accuracy. This makes it impossible to perform layered cutting or local repair of the carpet pile, affecting the smoothing effect.

[0006] In summary, existing carpet smoothing equipment is still unable to meet the multiple performance requirements of multi-head linkage trimming, layered adjustable cutting, simultaneous dust collection and processing, and compact integrated structure. There is an urgent need for an improved device with a reasonable structure, flexible control, high-efficiency trimming, and easy cleaning and maintenance, so as to achieve layered smoothing and repair of carpet pile, and improve carpet processing quality and work efficiency. Utility Model Content

[0007] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0008] Therefore, the technical solution adopted by this utility model is as follows: a multi-blade carpet layering and smoothing machine, comprising: a slide base, several guide rollers, and a drive unit fixed to the top surface of the slide base. The surface of the slide base is provided with several workstation slots arranged in a straight line, and each guide roller is driven to rotate by the drive unit and is respectively arranged inside the corresponding workstation slot. A main unit housing is fixedly installed on the top surface of the slide base, and the surface of the main unit housing is provided with a control handle for handheld operation and control.

[0009] The drive unit includes a drive box, and both the crank arm and the control cylinder are rotatably mounted inside the drive box. One end of the crank arm is hinged to the inside of the drive box, and the output end of the control cylinder is movably connected to the surface of the crank arm to control the deflection angle of the crank arm. The two ends of the crank arm are respectively provided with an output motor and a dust collection hub. The output motor is used to transmit power to the end of the guide roller body through the built-in pulley assembly structure to realize rotational trimming.

[0010] In a preferred embodiment, the control grip is further configured such that: the surface of the control grip is provided with a control switch electrically connected to the input terminal of the output motor, and the surface of the control grip is provided with several control knobs for corresponding connection with each control cylinder to independently adjust the deflection posture of each crank arm, thereby realizing the layered trimming adjustment of multiple guide rollers.

[0011] Specifically, by combining the knob with the electronic control system, precise height control can be achieved to meet the different trimming needs of multi-layer carpets or areas with uneven thickness.

[0012] In a preferred embodiment, the dust collection hub is further configured such that: the dust collection hub is fixedly disposed on the outside of the crank arm, and both ends of the dust collection hub are sleeved on the guide roller body; a vacuum cleaner structure is provided inside the slide block for absorbing the wool debris generated during trimming; and the vacuum cleaner feed port is connected to the surface of the dust collection hub.

[0013] Specifically, during the rotation and trimming process of the guide roller, the lint can be simultaneously sucked into the dust collection hub and then collected by a vacuum cleaner, which improves the dust collection efficiency and keeps the device running stably.

[0014] In a preferred embodiment, the output motor is further configured such that the output shaft is coaxially arranged with the connection point of the crank arm and the drive box, and the output motor is connected to the end of the guide roller body through the pulley set built into the crank arm, thereby achieving stable and synchronous power output.

[0015] Specifically, this structure can significantly reduce the interference caused by shaft misalignment to the transmission structure and improve the operational stability of the tool head during cutting.

[0016] In a preferred embodiment, the control cylinder is further configured such that: the surface of the control cylinder is provided with a pivot pin connected to the inside of the drive box, and the output end of the control cylinder is provided with a ball joint connector connected to the surface of the crank arm, thereby achieving high degree of freedom control.

[0017] Specifically, through the ball joint connection structure, the crank arm can maintain a stable connection during multi-angle deflection, improving the flexibility of control during the adjustment process.

[0018] In a preferred example, the configuration is further as follows: a plurality of guide rollers are arranged in parallel along the surface of the slide seat, and the bottom surface of each guide roller is spaced from the top surface of the slide seat, the spacing increasing progressively along the traveling direction of the slide seat.

[0019] Specifically, by using guide rollers arranged at different heights, multi-segment trimming can be achieved during carpet trimming, avoiding excessive cutting at once that could cause the pile to break or result in uneven trimming.

[0020] In a preferred embodiment, the dust collection hub is further configured as follows: the dust collection hub is a hollow disc-shaped box, the dust collection hub and the guide roller are arranged coaxially, and the dust collection hub is rotatably sleeved on the end of the guide roller.

[0021] Specifically, this structure not only facilitates stable and synchronized dust collection paths, but also makes assembly, disassembly, maintenance, and cleaning operations easier.

[0022] By combining the above technical solutions, this utility model can effectively achieve multi-level trimming, adjustable layer cutting, and simultaneous dust collection on the carpet surface, significantly improving work quality and efficiency, and is widely applicable to the production or renovation of various types of carpets.

[0023] The beneficial effects achieved by this utility model are as follows:

[0024] 1. In this utility model, by arranging multiple guide rollers at a gradient spacing along the top surface of the slide block to form a progressive shearing structure, multi-level layered trimming can be achieved during carpet trimming, significantly improving the uniformity and surface flatness of trimming, effectively avoiding problems such as trimming breaks, missed trimming, excessive length in some areas, or accumulation and blockage caused by one-time deep trimming, and improving the overall trimming quality and continuous operation efficiency.

[0025] 2. In this utility model, the guide roller body has stable and efficient independent driving and height adjustment capabilities through the crank arm structure with embedded pulley group connection, motor drive structure and control cylinder adjustment mechanism; with the cavity dust collection hub box and the built-in vacuum cleaner structure of the slide seat, synchronous dust collection operation is realized in the process of material trimming, which greatly reduces the debris residue and manual cleaning burden, and further improves the automation level and ease of use of the equipment.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0034] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0035] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a multi-blade carpet layering and smoothing machine.

[0036] Combination Figures 1-4 As shown, the present invention provides a multi-blade carpet layering and smoothing machine, which includes a slide plate seat 100, a plurality of guide rollers 200, and a drive unit 300 fixedly installed on the top surface of the slide plate seat 100.

[0037] The slide block 100 has an overall curved structure, and its top surface has several work station slots 120 arranged in a straight line. Each guide roller 200 is arranged inside the work station slot 120. The front end of the slide block 100 is provided with a main housing 110, and the surface of the main housing 110 is provided with a control handle 111 for hand-held control by the operator. The surface of the control handle 111 is provided with control switches for controlling the operation of each motor 321, and control knobs corresponding to each control cylinder 340 for adjusting the shearing depth of each guide roller 200.

[0038] The drive unit 300 is mounted on the top surface of the slide block 100 and includes a drive box 310, a crank arm 320, a dust collection hub 330, a motor 321, and a control cylinder 340. The crank arm 320 is rotatably mounted inside the drive box 310, with one end of the crank arm 320 hinged to the inner wall of the drive box 310. The output end of the control cylinder 340 is rotatably connected to the surface of the crank arm 320 via a ball joint connector, used to adjust the angle of the crank arm 320 relative to the drive box 310, thereby controlling the trimming depth of the guide roller body 200.

[0039] Motors 321 and dust collection hubs 330 are respectively installed at both ends of the crank arm 320. The motor 321 is connected to the end of the guide roller body 200 through a pulley assembly structure inside the crank arm 320, driving the guide roller body 200 to achieve high-speed rotation and trimming. The output shaft of the motor 321 is coaxially arranged with the hinge point of the crank arm 320 and the drive box 310, effectively improving transmission stability and driving efficiency. The dust collection hub 330 is a hollow disc-shaped box, whose outer surface is coaxially arranged with the guide roller body 200 and can be rotatably sleeved on the end of the guide roller body 200. During the material trimming process, it is used to collect debris and guide it into the vacuum cleaner structure inside the slide plate seat 100, improving cleaning efficiency and automation.

[0040] The guide rollers 200 are arranged parallel to each other along the traveling direction of the slide block 100. The bottom surface of each guide roller 200 is spaced at different heights from the top surface of the slide block 100, and this distance gradually increases along the advancing direction of the slide block 100. This structural design allows the guide rollers 200 of different heights to achieve multi-level layered shearing and trimming during carpet advancement, avoiding problems such as missed cuts, wool entanglement, jamming, or waste accumulation that can occur with single-stage trimming. This effectively improves the flatness and shearing quality of the carpet surface.

[0041] During operation, the operator moves the equipment by controlling the handle 111. Multiple drive boxes 310 in the drive unit 300 control the rotation and shearing depth of the corresponding guide rollers 200. The control cylinder 340 adjusts the swing angle of the crank arm 320, causing the motor 321 to drive the guide rollers 200 to effectively layer and trim the carpet. The resulting fabric debris is collected in the dust collection hub 330 and removed by a vacuum cleaner inside the slide plate base 100, achieving efficient cleaning and a closed-loop operation.

[0042] In summary, this implementation method has good operational stability, multi-stage trimming capability, and efficient dust collection function, making it particularly suitable for flat carpet finishing operations on large areas.

[0043] This utility model provides a multi-blade carpet layering and smoothing machine, mainly used for multi-level layering and finishing operations on carpet materials. Its working principle is as follows:

[0044] During operation, the operator propels and controls the machine by holding the control handle 111 located on the surface of the main housing 110. The control handle 111 is equipped with control switches connected to each motor 321 and control knobs corresponding to each control cylinder 340, which facilitates real-time adjustment of the rotation status and shearing depth of the multiple guide rollers 200.

[0045] The drive unit 300 includes a drive box 310 with a crank arm 320. One end of the crank arm 320 is hinged to the inside of the drive box 310, and the other end houses a motor 321 for driving and a dust collection hub 330 connected to the dust collection structure. The motor 321 is connected to the guide roller body 200 via a pulley assembly built into the crank arm 320, driving the guide roller body 200 to rotate at high speed to achieve material cutting. The control cylinder 340 is connected to the crank arm 320 via a ball joint connector, enabling control of the crank arm's deflection angle and thus achieving dynamic adjustment of the shearing depth.

[0046] In actual trimming operations, the carpet to be processed is fed along the surface of the slide plate 100. Each guide roller 200 is sequentially positioned within a linearly arranged work station groove 120. A certain distance is maintained between the bottom surface of each guide roller 200 and the top surface of the slide plate 100, and the height between each guide roller increases progressively in the direction of travel, forming a layered trimming path. Through the coordinated action of multiple sets of guide rollers 200, multi-level, precise, and stable shearing processing of the carpet surface is achieved, effectively avoiding issues such as missing or tangled fibers caused by single-stage trimming.

[0047] Hair debris generated during trimming is guided into the dust collection hub 330 and collected by the vacuum cleaner structure inside the slide base 100. The dust collection hub 330 is connected to the vacuum cleaner's inlet, forming an effectively sealed suction channel to prevent hair debris from scattering and improve cleaning efficiency.

[0048] In summary, this utility model integrates a multi-blade shearing mechanism, an independent drive component, and a closed dust collection structure to achieve multi-stage trimming, depth control, and automatic dust collection of carpet materials, possessing significant advantages such as convenient operation, stable trimming, and efficient dust collection.
