Description

Technical Field

[0001] This utility model relates to the field of sponge flat cutting technology, specifically a disc-type sponge flat cutting machine with stable feeding. Background Technology

[0002] As described in the published patent CN216707626U, "A Sponge Disc Flat Cutting Machine with a Guided Feeding Structure," a sponge is a porous material with good water absorption, suitable for cleaning items. Commonly used sponges are made from wood cellulose fibers or foamed plastic polymers. Additionally, there are natural sponges made from sponge animals, most of which are used for body cleaning or painting. Furthermore, there are three other types of synthetic sponges made from different materials: low-density polyether non-absorbent sponge, polyvinyl alcohol superabsorbent material (without obvious pores), and polyester.

[0003] Existing disc cutting machines for sponges place the sponges on the cutting machine during use, which may cause the sponges to shift during cutting, resulting in inaccurate cutting.

[0004] As described in the published patent CN105171808B, "A Fully Automatic Sponge Disc Flat Cutting Machine", the sponge in the existing flat cutting machine is placed freely on the platform. The friction between the sponge and the platform is entirely determined by the weight of the sponge. As a result, when cutting high-density sponges, the sponge is often not heavy enough, causing relative movement between the sponge and the platform, resulting in inaccurate cutting thickness. In summary, during the cutting process of some existing sponge disc cutting machines, there is a problem that the sponge is prone to deviation. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A disc-type sponge flat cutter with stable feeding includes a base, on which a working disc is rotatably mounted. A mounting hole is formed at the center of the working disc, and a pushing mechanism is provided in the mounting hole. An arched mounting arm fixed to the base is installed on the outer side of the working disc. The end of the arched mounting arm extends into the top of the mounting hole. An electric heating cutting blade spanning the working disc is installed on the arched mounting arm. The pushing mechanism includes a mounting plate, which is installed in a mounting hole and fixedly mounted on a base. A mounting column is rotatably mounted on the upper end face of the mounting plate, and a pushing rod for pushing the sponge is fixed on the mounting column. A motor component for driving the mounting column to rotate is fixed on the lower end face of the mounting plate. The push rod and the arched mounting arm are respectively equipped with a first infrared detection probe and a second infrared detection probe for detecting the sponge feeding position.

[0007] As a further embodiment of this utility model: the push rod includes a connecting rod fixedly connected to the mounting column and a push rod fixedly connected to the connecting rod; The extension line of the connecting rod passes through the center of the working disk, and the push rod and the connecting rod are formed with an obtuse angle.

[0008] As a further embodiment of this utility model: a dovetail piece with a width greater than that of the push rod is fixed on the side of the push rod closer to the sponge, and a dovetail groove is formed on the side of the dovetail piece closer to the sponge.

[0009] As a further embodiment of this utility model: the second infrared detection probe is installed in the dovetail groove.

[0010] As a further embodiment of this utility model: a first mounting seat is fixedly provided on the upper end face of the mounting plate, a first bearing component is mounted on the first mounting seat, the outer ring of the first bearing component is fixedly provided on the first mounting seat, the mounting post is fixedly provided on the inner ring of the first bearing component, and the lower end of the mounting post passes downward through the mounting plate and is fixedly connected to the working shaft of the motor component.

[0011] As a further embodiment of this utility model: a second mounting seat is fixedly provided on the lower end face of the mounting plate, a second bearing component is mounted on the second mounting seat, the outer ring of the second bearing component is fixedly provided on the second mounting seat, the mounting post is fixedly provided on the inner ring of the second bearing component, and the lower end of the mounting post is fixedly connected to the working shaft of the motor component.

[0012] As a further embodiment of this utility model: a washer is fitted on the mounting column, the upper end of the washer abutting against the connecting rod, and the lower end of the washer abutting against the first mounting seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The mounting plate fixed to the base ensures the stability of the entire pushing base. The motor drives the mounting column to rotate the pushing rod stably, applying a continuous and uniform pushing force to the sponge along the cutting direction. This not only effectively overcomes cutting resistance but also compensates for the unreliability of relying solely on the friction generated by the sponge's own weight. This ensures that sponges of various densities can be fed smoothly and linearly along the working disc surface during the cutting process, completely avoiding problems such as tilted cut surfaces, uneven thickness, or even defective products caused by poor sponge movement or deviation. Ultimately, this significantly improves cutting accuracy and consistency while reducing manual intervention, thus significantly increasing production efficiency and product quality. This utility model of a disc-type sponge flat cutter uses a motor in the pushing mechanism to drive the pushing rod to rotate continuously, applying a stable pushing force to the sponge. This ensures that the sponge moves smoothly on the working disc without shifting, thus effectively avoiding the problem of deviation during the cutting process and improving cutting accuracy and work efficiency.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-9A disc-type sponge flat cutter with stable feeding includes a base 100, on which a working disc 101 is rotatably mounted. A mounting hole 102 is opened at the center of the working disc 101, and a pushing mechanism 103 is provided in the mounting hole 102. An arched mounting arm 104 fixed to the base 100 is installed on the outer side of the working disc 101. The end of the arched mounting arm 104 extends into the top of the mounting hole 102. An electrothermal cutting blade 105 spanning across the working disc 101 is installed on the arched mounting arm 104. The pushing mechanism 103 includes a mounting plate 106, which is installed in the mounting hole 102 and fixedly mounted on the base 100. A mounting column 107 is rotatably mounted on the upper end face of the mounting plate 106. A pushing rod for pushing the sponge is fixed on the mounting column 107. A motor component 109 for driving the mounting column 107 to rotate is fixed on the lower end face of the mounting plate 106. The push rod and the arched mounting arm 104 are respectively equipped with a first infrared detection probe 110 and a second infrared detection probe for detecting the sponge feeding position. The design of the pushing mechanism 103 fundamentally solves the problem of displacement and deviation caused by insufficient friction between the sponge and the platform in traditional equipment. Specifically, the sponge is first placed on the working disc 101. The rotation of the working disc 101 drives the sponge to be fed. Based on the data feedback from the first infrared detection probe 110 on the pushing rod, the servo motor 109 drives the pushing rod to abut against the back of the sponge. The servo motor 109 follows the angular velocity of the working disc 101 and synchronously drives the pushing rod (the first infrared detection probe 110 performs distance detection. When it finds that there is no sponge in front, it controls the pushing rod to rotate at an angular velocity greater than that of the working disc until it captures the sponge). When the sponge is about to enter the cutting position, the second infrared detection probe on the arched mounting arm 104 will detect the approach of the sponge. The servo motor 109 drives the pushing rod to push the sponge. The arched mounting arm 104 is positioned above the push rod and does not interfere with the push rod. The mounting plate 106 fixed to the base 100 ensures the stability of the entire pushing base. The motor 109 drives the mounting column 107 to rotate the pushing rod stably, applying a continuous and uniform pushing force along the cutting direction to the sponge. This not only effectively overcomes the cutting resistance, but also makes up for the unreliable method of relying solely on the friction force generated by the weight of the sponge. This ensures that sponges of various densities can be fed smoothly and linearly along the surface of the working disc 101 during the cutting process, completely avoiding problems such as tilting of the cutting surface, uneven thickness, or even scrap caused by poor sponge movement or deviation. Ultimately, while greatly improving the cutting accuracy and consistency, it also reduces manual adjustment intervention, significantly improving production efficiency and product quality. It should be noted that the main protection point of this application is the pushing mechanism 103. In the prior art, the arched mounting arm 104 is generally equipped with a lifting component for adjusting the height of the electrothermal cutting blade 105. Therefore, the general technology of the lifting and adjusting method of the electrothermal cutting blade 105 will not be described here. Meanwhile, the rotation of the working disc 101 is driven by an auxiliary power component. The installation and transmission structure of the working disc 101 are common technologies and will not be described in detail here. This utility model of a disc-type sponge flat cutter uses a motor in the pushing mechanism 103 to drive the pushing rod to rotate continuously, applying a stable pushing force to the sponge. This ensures that the sponge moves smoothly on the working disc 101 without shifting, thereby effectively avoiding the problem of deviation during the cutting process and improving cutting accuracy and work efficiency.

[0017] In this embodiment of the utility model, the push rod includes a connecting rod 112 fixedly connected to the mounting post 107 and a push rod 113 fixedly connected to the connecting rod 112. The extension line of the connecting rod 112 passes through the center of the working disk 101, and the push rod 113 and the connecting rod 112 are formed with an obtuse angle. like Figure 4 As shown, the electrothermal cutting disc 105 is arranged along a straight line L1. An obtuse angle is formed between the push rod 113 and the connecting rod 112. During the process of pushing the sponge, the sponge comes into contact with the electrothermal cutting disc 105 in a surface-to-surface manner. like Figure 5 As shown, if the push rod 113 is set along the straight line L2 passing through the center of the circle, then under the action of the push rod 113, the sponge will contact the electrothermal cutting plate 105 in a point contact manner, and the sponge may deviate due to uneven force. The push rod 113 and the connecting rod 112 form an obtuse angle, and the extension line of the connecting rod 112 passes through the center of the disk. This guides the sponge to approach the electrothermal cutting blade 105 at an optimized angle, so that its front side smoothly abuts and slides over the cutting blade in a wide "surface contact" manner rather than "point or line contact". This greatly enhances the stability of the sponge at the moment of cutting, effectively prevents local compression, deformation or displacement caused by uneven force, thereby ensuring the flatness and perpendicularity of the cutting surface and significantly improving the cutting accuracy and quality.

[0018] In this embodiment of the present invention, a dovetail member 114 with a width greater than that of the push rod 113 is fixed on the side of the push rod 113 near the sponge, and a dovetail groove 115 is formed on the side of the dovetail member 114 near the sponge. The dovetail 114 and its dovetail groove 115 added to the push rod allow the dovetail groove 115 to be slightly embedded in the sponge body, significantly increasing the contact area with the sponge and providing excellent interlocking friction. This effectively suppresses the sponge's vertical jumping and lateral deviation during the pushing process, ensuring extremely smooth and precise pushing action. It fundamentally reduces the dimensional deviation and uneven cut surface caused by the sponge sliding or twisting during cutting.

[0019] In this embodiment of the present invention, the second infrared detection probe is installed in the dovetail groove 115; The design embeds the second infrared detection probe within the dovetail groove 115, enabling it to directly and accurately detect the contact between the push rod 113 and the sponge. This allows for real-time and precise monitoring of the sponge's pushing status. Furthermore, this built-in layout effectively avoids potential collision damage to the external probe and eliminates detection errors caused by installation position deviations, further ensuring the stability and reliability of the pushing and cutting process.

[0020] In this embodiment of the utility model, a first mounting seat 116 is fixedly provided on the upper end face of the mounting plate 106, a first bearing component 117 is mounted on the first mounting seat 116, the outer ring of the first bearing component 117 is fixedly provided on the first mounting seat 116, the mounting post 107 is fixedly provided on the inner ring of the first bearing component 117, and the lower end of the mounting post 107 passes downward through the mounting plate 106 and is fixedly connected to the working shaft of the motor component 109. The first mounting base 116 and the first bearing 117 work together to provide a stable and high-precision rotational support for the mounting column 107. The first bearing 117 effectively distributes the friction and radial load in the rotational motion evenly, ensuring the smoothness and coaxiality of the rotation of the mounting column 107 and the push rod above it. This greatly reduces vibration and energy loss, making the drive of the motor 109 more efficient and reliable, and ultimately ensuring the extreme smoothness and precision of the sponge pushing process.

[0021] In this embodiment of the utility model, a second mounting base 119 is fixedly provided on the lower end face of the mounting plate 106, a second bearing component 120 is mounted on the second mounting base 119, the outer ring of the second bearing component 120 is fixedly provided on the second mounting base 119, the mounting post 107 is fixedly provided on the inner ring of the second bearing component 120, and the lower end of the mounting post 107 is fixedly connected to the working shaft of the motor component 109. By adding a second mounting base 119 and a second bearing component 120 to the lower end face of the mounting plate 106, a robust dual-point support system is formed together with the upper bearing support. This greatly enhances the radial stability and bending stiffness of the mounting column 107, enabling it to effectively suppress axial sway and vibration when subjected to uneven loads. This ensures the accuracy and consistency of the push rod's rotation trajectory, while significantly reducing the radial load on the motor component 109 and improving the overall smoothness of the drive system, mechanical life, and transmission efficiency.

[0022] In this embodiment of the utility model, a washer 121 is fitted on the mounting post 107, the upper end of the washer 121 abuts against the connecting rod 112, and the lower end of the washer 121 abuts against the first mounting seat 116. By setting a washer 121 on the mounting column 107, with its upper end abutting against the connecting rod 112 and its lower end abutting against the first mounting seat 116, the axial gap between the rotating component and the fixed support is effectively filled, which plays a buffering and stabilizing role, significantly reducing axial movement and vibration noise during device operation, while reducing wear between the connecting rod 112 and the first mounting seat 116, extending the service life of key components, and further ensuring the stability and reliability of the pushing mechanism 103 during long-term operation.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
