Description

Technical Field

[0001] This utility model relates to the field of sponge processing technology, specifically to a feeding device for a sponge straight cutting machine. Background Technology

[0002] As described in the published patent CN216992288U, "A Sponge Straight Cutting Machine with Automatic Feeding Device", a straight cutting machine generally refers to a machine used for cutting sponges. A heated iron wire is built on the frame 100, and the sponge is cut by using the principle of heat melting. In particular, in the production of clothing, sofas and other products, it is often necessary to use a straight cutting machine to cut sponge raw materials into sponge blocks of appropriate size for processing.

[0003] Existing straight cutting machines have a simple structure, generally consisting of a frame and a heating wire. Although the structure is simple, the operation is relatively complex and requires experienced operators. First, the operator needs to be able to make reasonable use of the raw materials according to the processing dimensions. Second, after neatly stacking the raw materials, they need to make precise cuts. During the cutting process, it is also necessary to control the heating power of the heating wire and the pushing speed of the straight cutting machine. In particular, it is difficult to push the machine smoothly and slowly according to the heating wire power. This results in problems such as high wages for skilled workers who can operate sponge straight cutting machines, but slow processing speed.

[0004] As described in the published patent CN222904148U, "A Sponge Straight Cutting Machine with Stable Material Guiding", a sponge is a porous material with good water absorption and can be used to clean items. Commonly used sponges are made of wood cellulose fibers or foamed plastic polymers. There are also natural sponges made from sponge animals. Most natural sponges are used for body cleaning or painting. There are also three other types of synthetic sponges made of materials, namely low-density polyether, polyvinyl alcohol and polyester.

[0005] In the production of sponges, straight cutting machines are used. Traditional straight cutting machines require a conveyor belt to transport the sponge to the bottom of the machine before it is cut. However, the conveyor belt can easily cause the sponge to shift during transport, making it impossible to accurately align the sponge.

[0006] In summary, some existing sponge cutting machines suffer from problems such as inconvenient control of feeding speed and feeding deviation. Utility Model Content

Detailed Implementation

[0029] 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.

[0030] Please see Figure 1-6 A feeding device for a sponge straight cutting machine includes a frame 100, on which a conveying assembly 101, a clamping assembly 102 and a positioning assembly 103 are provided;

[0031] The conveying assembly 101 includes a slide rail 104 fixed on the frame 100, a slider 105 on the slide rail 104, a bearing plate 106 fixed on the slider 105, and a left bearing cylinder 107 and a right bearing cylinder 108 fixed at both ends of the bearing plate 106, respectively. The working axes of the left bearing cylinder 107 and the right bearing cylinder 108 extend upward through the bearing plate 106.

[0032] The clamping assembly 102 includes a material carrier plate 110 spanning and fixedly mounted on the upper ends of the left bearing cylinder 107 and the right bearing cylinder 108. A portal frame 111 is provided above the material carrier plate 110. The left and right ends of the portal frame 111 are fixedly connected to the working shafts of the left bearing cylinder 107 and the right bearing cylinder 108, respectively. A lifting assembly 112 for clamping the sponge material is installed on the upper end of the portal frame 111.

[0033] The positioning component 103 includes a positioning cylinder 113 fixed to one side of the portal frame 111, and a positioning push plate 114 is fixed on the working shaft of the positioning cylinder 113.

[0034] The conveying assembly 101, consisting of the slide rail 104, the slider 105, and the bearing plate 106, combined with the lifting assembly 112 to clamp the sponge material, can achieve smooth and uniform propulsion of the sponge material along a straight path, so that the heating power of the heating wire and the feeding of the sponge material are precisely matched. This fundamentally solves the problem that the manual propulsion speed is difficult to control and prone to fluctuation, ensuring the stability of the cutting process.

[0035] The lifting assembly 112 is mounted on a rigid gantry bracket 111, which spans the material carrier plate 110 and is fixed to the working shafts of the left and right bearing cylinders at both ends. This design ensures that the downward pressure applied by the lifting assembly 112 can be evenly transmitted to the sponge material, effectively preventing the sponge from being squeezed and deformed or torn locally due to uneven force during the cutting process, and ensuring the flatness of the cut surface.

[0036] By precisely controlling the lifting and lowering of the left-side bearing cylinder 107 and the right-side bearing cylinder 108, the height of the gantry bracket 111 can be easily adjusted, allowing the lifting assembly 112 on the gantry bracket 111 to better clamp the sponge material. This eliminates the need to rely on the operator's experience and feel, reducing the difficulty of operation and the dependence on skilled workers. The gantry bracket 111 and the lifting assembly 112 move as a whole, which means that during the feeding process, the clamping force is always applied to the sponge, preventing it from shifting or shaking due to inertia or changes in friction during the advancement process, thus improving cutting accuracy.

[0037] The positioning cylinder 113 drives the positioning push plate 114, which can push the side of the sponge in real time during the feeding process or before cutting. Through the active action of the positioning push plate 114, it can promptly correct the slight lateral deviation of the sponge that may occur during the conveying process (such as due to uneven friction or slight irregularity of the raw material itself), ensuring that the sponge always moves along the preset cutting path, which greatly improves the positioning accuracy.

[0038] This utility model's feeding device achieves stable and speed-controllable linear material conveying through the coordinated action of the slide rail 104, slider, and bearing plate 106. The gantry bracket 111 and lifting assembly 112 ensure that the sponge is evenly and reliably clamped and fixed during the cutting process to prevent deformation. At the same time, the positioning cylinder 113 drives the push plate to correct the sponge position in real time and eliminate deviation. Overall, it significantly improves the stability, accuracy, and automation of feeding, effectively solving the technical problems of difficult manual operation, uncontrollable propulsion speed, and easy deviation of sponge conveying in traditional straight cutting machines. This improves cutting quality, efficiency, and raw material utilization, while reducing reliance on skilled workers and overall production costs.

[0039] In this embodiment of the utility model, a limiting component 115 is fixedly provided on the gate-shaped bracket 111. The limiting component 115 includes a limiting mounting plate 116 fixedly provided on the gate-shaped bracket 111. A left limiting mounting block 117 and a right limiting mounting block 118 are symmetrically fixed on the left and right sides of the limiting mounting block 117 and the right limiting mounting block 118. Vertical limiting grooves 119 are respectively opened on the opposite sides of the left limiting mounting block 117 and the right limiting mounting block 118. A limiting plate 120 is slidably installed in the limiting groove 119. A plurality of first insertion holes 121 are vertically arrayed on the limiting plate 120. A second insertion hole 122 is opened on the limiting mounting plate 116 to align and cooperate with the first insertion holes 121 one by one.

[0040] The limiting plate 120 is guided to slide up and down by the left and right symmetrical limiting grooves 119. Combined with the precise alignment of the array-type first insertion hole 121 and the second insertion hole 122 on the limiting mounting plate 116 and the pin fixation, the height of the limiting plate 120 is flexibly adjustable and firmly locked. This allows it to accurately adapt to the processing requirements of sponges of different thicknesses. During the cutting process, it effectively limits the vertical displacement or upward arching deformation of the sponge (because the sponge raw material is generally long), ensuring that the sponge is always stably clamped and transported within the preset plane. At the same time, it significantly improves the stability during the cutting process.

[0041] Furthermore, the limiting plate 120 can slide up and down within the vertical limiting grooves 119 of the left limiting mounting block 117 and the right limiting mounting block 118. Combined with the multiple first insertion holes 121 arrayed on the limiting plate 120 and the corresponding second insertion holes 122 on the limiting mounting plate 116, the operator can adjust the limiting plate 120 to a suitable height position according to the thickness of the sponge raw material being processed. For the same batch of sponge, the thickness of qualified products is generally consistent. By adjusting the limiting plate 120 to a suitable height (slightly higher than the upper surface of the sponge raw material), sponge raw materials that do not meet the height requirements can be limited, thereby detecting defective sponge raw materials in advance and preventing defective products from entering the cutting station (due to internal gaps or foreign objects causing abnormal thickness), thus improving efficiency while increasing cutting safety.

[0042] This design allows the device to quickly and easily adapt to sponge raw materials of different thicknesses without the need to replace parts or make complex mechanical adjustments, greatly improving the equipment's versatility and production change efficiency.

[0043] Once the limiting plate 120 has slid to the desired height, the limiting plate 120 can be securely locked in that position by simultaneously inserting the pin (or bolt or other fastener) into the aligned first socket 121 and second socket 122.

[0044] This socket alignment and locking method provides reliable mechanical fixation, ensuring that even under the rebound force of the sponge during subsequent cutting, the limiting plate 120 can remain in an absolutely unchanged position, preventing it from loosening or slipping, and ensuring the continuous and stable limiting effect.

[0045] In this embodiment of the utility model, the gate-shaped bracket 111 includes a left bracket 123 and a right bracket 124 located at both ends, and a transverse bracket 125 fixedly connected to the upper ends of the left bracket 123 and the right bracket 124. The lifting assembly 112 includes a clamping cylinder 126 fixedly mounted on the transverse bracket 125. The working shaft of the clamping cylinder 126 extends downward from the transverse bracket 125, and a clamping plate 127 is fixedly mounted on the working shaft of the clamping cylinder 126.

[0046] Through the direct rigid connection between the clamping cylinder 126 and the clamping plate 127, and with the stable support provided by the transverse bracket 125, a precise, efficient, and uniform clamping force is applied in the vertical direction. Its structure is simple and compact. The working shaft of the clamping cylinder 126 drives the clamping plate 127 vertically downward, ensuring that the downward pressure is applied directly to the central area of ​​the sponge material without deviation, effectively preventing deformation, displacement, or edge lifting of the sponge due to uneven local pressure. At the same time, this design is responsive, with controllable clamping force and stable reliability.

[0047] In this embodiment of the present invention, guide shafts 128 are fixedly provided at both ends of the clamping plate 127, and guide holes 129 that slide with the guide shafts 128 are provided on the transverse support 125.

[0048] The sliding fit structure between the guide shaft 128 and the guide hole 129 provides a rigid vertical guide constraint for the clamping plate 127, effectively eliminating the radial sway or lateral load that may occur during the extension and retraction of the working shaft of the clamping cylinder 126. This ensures that the clamping plate 127 always moves smoothly up and down along a strictly vertical trajectory. This not only significantly improves the accuracy and reliability of the clamping action and prevents unilateral pressure damage or local clamping failure of the sponge caused by the tilt of the clamping plate 127, but also greatly reduces the lateral force borne by the working shaft of the cylinder and the seals, reduces uneven wear, extends the service life of key components, and ensures that the clamping force is uniformly and vertically transmitted to the sponge material.

[0049] In this embodiment of the utility model, the frame 100 is provided with an auxiliary slide bar assembly 130. The auxiliary slide bar assembly 130 includes a front support plate 131 and a rear support plate 132 that are respectively horizontally arranged at the front and rear ends of the slide rail 104. The front support plate 131 and the rear support plate 132 are respectively fixed on the frame 100. A left slide bar 133 and a right slide bar 134 are respectively fixedly connected to the two sides of the front support plate 131 and the rear support plate 132. A left slider 135 and a right slider 136 are respectively slidably arranged on the left slide bar 133 and the right slider 134. The left slider 135 and the right slider 136 are respectively fixedly connected to the left and right sides of the material plate 110.

[0050] The auxiliary slide bar assembly 130, through the front support plate 131, the rear support plate 132, and the left slide bar 133 and right slide bar 134 fixed to its two sides, together with the left slider 135 and right slider 136 fixedly connected to the left and right sides of the carrier plate 110, provides rigid sliding support for the carrier plate 110 on both sides and along its entire length. This significantly enhances the overall rigidity and torsional and bending resistance of the carrier plate 110 during load-bearing and movement, and effectively prevents the carrier plate 110 from twisting, sagging, or tilting due to the weight of the sponge or the effects of clamping force and cutting resistance.

[0051] The double-sided slide bar-slider structure is like adding two sturdy "track legs" to the material carrier plate 110, expanding its motion support point from a single point (main slide rail 104) to three points (or a wider surface support). This multi-point, wide-base support greatly improves the motion stability of the material carrier plate 110 in the horizontal plane, effectively suppressing the left-right swaying, front-back pitching, or slight torsion around the vertical axis of the material carrier plate 110 during movement (especially during start-up, stop, or speed change). The precise cooperation of the double-sided slide bar-slider distributes the load of the main conveying slide rail 104, ensuring that the material carrier plate 110 moves more smoothly and horizontally throughout the entire conveying process, significantly reducing vibration and offset, thereby synergistically improving the stability, positioning accuracy, and cutting quality of material conveying, and extending the service life of the main conveying assembly 101.

[0052] In this embodiment of the utility model, a feeding base plate 137 is also fixed between the front support plate 131 and the rear support plate 132, and the feeding base plate 137 is installed below the material carrier plate 110.

[0053] On the one hand, the feeding base plate 137 acts as a physical barrier to effectively prevent sponge debris from falling vertically, avoiding debris from intruding into precision moving parts such as slide rails and sliders, which could lead to jamming, increased wear, or loss of precision, thus significantly improving the reliability and service life of the equipment. On the other hand, the feeding base plate 137 provides continuous and stable bottom support for long materials that exceed the support range of the carrying plate 110, preventing the material from sagging or twisting due to its own weight during the conveying process, ensuring that the long material remains straight for precise cutting. At the same time, the feeding base plate 137, together with the front support plate 131 and the rear support plate 132, forms a reinforcing structure that further improves the overall rigidity of the auxiliary conveying component 101, synergistically optimizing the feeding stability and cutting quality, and significantly reducing the frequency and difficulty of cleaning and maintenance.

[0054] In this embodiment of the present invention, the frame 100 is further provided with an auxiliary feeding assembly 138. The auxiliary feeding assembly 138 includes a side plate 139 fixed on the frame 100. A pusher plate 140 is mounted on the side plate. The pusher plate 140 has a side groove 141 that slides and engages with the side plate. A threaded rod 142 is rotatably mounted on the frame 100. A drive motor 143 for driving the threaded rod 142 is mounted at the end of the threaded rod 142. One side of the pusher plate 140 is screwed into the threaded rod 142.

[0055] The auxiliary feeding assembly 138 is precisely screwed into the pusher plate 140 via the threaded rod 142. Under the control of the drive motor 143, it enables the pusher plate 140 to move linearly and reciprocally along the side plate 139 with adjustable speed and high precision, providing a stable and controllable auxiliary feeding capability for the feeding device. The auxiliary feeding assembly 138 is compact and independent, and is particularly suitable for processing large-size sponges. It significantly expands the processing adaptability and operational flexibility of the equipment, making the overall feeding process more stable and efficient, and the cutting positioning more accurate and reliable.

[0056] 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.
