[0002] Flexible rubber hoses have a wide range of applications in industrial production, daily life, and many other fields. In practical use, flexible rubber hoses often need to be cut according to specific requirements.

[0003] However, due to the soft nature of the flexible tubing, conventional clamps often rely solely on clamping force to fix the tubing during traditional cutting operations. This makes the tubing prone to deformation and shaking during cutting, which not only makes it difficult to accurately control the cutting position, but also results in unevenness, skewing, and other deformations at the cut ends of the tubing. Utility Model Content

[0004] Therefore, it is necessary to provide a deformation-resistant soft rubber tube cutter limiting clamp to address the problem that this causes the soft rubber tube to easily deform and wobble during cutting, making it difficult to accurately control the cutting position and causing unevenness, skewing and other deformation at the end of the soft rubber tube after cutting.

The fixed plate is provided in two sets, and both sets of fixed plates are fixedly mounted on the upper surface of the support platform. Both sets of limiting clamping plates are slidably mounted on the upper surface of the two sets of fixed plates. A cutting mechanism, comprising a cutting blade, a hydraulic push rod, and a support frame.

[0007] In one embodiment, the drive assembly further includes a motor, a driven gear, a toothed belt, and a driving gear. One end of each of the two sets of bidirectional screws passes through a corresponding fixing plate, and one end of each set of bidirectional screws is fixedly connected to the driven gear and the toothed belt, respectively. The motor is bolted to the upper surface of the support platform, and the output end of the motor is connected to the driving gear through a connecting post.

[0008] In one embodiment, the toothed belt is engaged with the outer arc surfaces of the driven gear and the driving gear, and a limiting cover for limiting the toothed belt is provided on the upper surface of the support platform.

[0009] In one embodiment, the anti-deformation component includes a negative pressure fan and a connecting hose. Two sets of negative pressure fans are provided, and the two sets of negative pressure fans are symmetrically arranged on the upper surface of the support platform.

[0013] Beneficial effects 1. The above-mentioned cutting limit clamp uses a drive component to move the limit clamping plates on the upper surface of the corresponding fixed plate, thereby limiting and clamping both ends of the cut of the soft rubber tube through four sets of limit clamping plates. Then, the anti-deformation component strengthens the clamping and anti-deformation effect of the soft rubber tube, thus preventing the soft rubber tube from deforming during the cutting process with the cooperation of the limit clamping plates and the anti-deformation component.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined Figures 1-5 This invention describes a deformation-resistant soft rubber tube cut-out limiting clamp.

[0020] In one embodiment, a deformation-resistant flexible hose slit limiting clamp includes: a support mechanism 100, which includes a support platform 101 and support rings 102, with two sets of support rings 102 fixedly disposed on the upper surface of the support platform 101; and a clamping mechanism 200, which includes a fixing plate 201, a limiting clamping plate 202, a driving assembly, and an anti-deformation assembly, with two sets of fixing plates 201 fixedly disposed on the upper surface of the support platform 101. Two sets of limiting clamps 202 are slidably arranged on the upper surface of the four sets of limiting clamps 202. The driving component includes a sliding block 210 and a bidirectional screw 211. Sliding blocks 210 are arranged on the lower surface of the four sets of limiting clamps 202. Two sets of bidirectional screws 211 are arranged. The two sets of bidirectional screws 211 are rotatably arranged inside the corresponding fixed plate 201. The outer arc surface of the two sets of bidirectional screws 211 is threadedly sleeved on the two sets of sliding blocks 210. The sliding blocks 210 are convex blocks. The two sets of fixed plates 201 are all provided with sliding grooves 213 corresponding to the sliding blocks 210. In this embodiment, two sets of support rings 102 are used to support the distal end of the soft rubber tube, thereby preventing the soft rubber tube inside the limiting clamp 202 from deforming due to the sagging of both ends of the soft rubber tube. The inner diameter of the two limiting clamps 202 after clamping is consistent with the outer diameter of the soft rubber tube, and anti-slip layers are provided at the positions where the air holes 212 are located on the inner side of the limiting clamp 202, thereby ensuring that the limiting clamp 202 can clamp and limit the soft rubber tube to a certain extent, while avoiding excessive clamping force that could deform the soft rubber tube. The tube is placed between two limiting clamps 202. Then, the bidirectional screw 211 rotates, causing two sets of sliding blocks 210 symmetrically arranged on the outer arc surface to move towards or away from each other. The sliding blocks 210 are convex blocks and are inserted into the sliding groove 213 to move, thereby preventing the sliding blocks 210 from rotating with the bidirectional screw 211. This causes the two limiting clamps 202 to move closer together, thereby clamping and limiting both ends of the soft rubber tube cut, thus ensuring that neither end of the soft rubber tube will be displaced or shaken during cutting.

[0021] like Figure 2 and Figure 3 As shown, the drive assembly also includes a motor 204, a driven gear 205, a toothed belt 206, and a driving gear 207. One end of each of the two sets of bidirectional screws 211 passes through the corresponding fixing plate 201. One end of each of the two sets of bidirectional screws 211 is fixedly connected to the driven gear 205 and the toothed belt 206, respectively. The motor 204 is bolted to the upper surface of the support platform 101, and the output end of the motor 204 is connected to the driving gear 207 through a connecting post. The toothed belt 206 meshes with the outer arc surface of the driven gear 205 and the driving gear 207. A limiting cover 208 for limiting the toothed belt 206 is provided on the upper surface of the support platform 101. In this embodiment, the starter motor 204 drives the drive gear 207 to rotate via the connecting column. The drive gear 207 drives the toothed belt 206 to rotate via meshing. The toothed belt 206 then drives the driven gear 205 to rotate via meshing, thereby driving the two sets of bidirectional screws 211 to rotate synchronously. This ensures that both limiting clamps 202 can clamp and limit the soft tube. At the same time, a limiting cover 208 is provided on the upper surface of the support platform 101 and covers the outside of the toothed belt 206 to limit the toothed belt 206 and prevent it from disengaging from the outer arc surface of the driven gear 205 and the drive gear 207 during rotation. This ensures the stability of the limiting clamps 202 during the clamping process of the soft tube.

[0022] like Figure 2 and Figure 3 As shown, the anti-deformation component includes a negative pressure fan 203 and a connecting hose 209. There are two sets of negative pressure fans 203, which are symmetrically arranged on the upper surface of the support platform 101. One set of negative pressure fans 203 is connected to two sets of limiting clamps 202 on the same side through the connecting hose 209. The inner side of each of the four sets of limiting clamps 202 is provided with an arc-shaped groove corresponding to the soft hose, and the arc-shaped groove is provided with several sets of air holes 212 communicating with the connecting hose 209. In this embodiment, after the two limiting clamps 202 clamp the soft rubber tube inside the arc-shaped groove, the negative pressure fan 203 is started. The negative pressure fan 203 is connected to several sets of air holes 212 through the connecting hose 209, so that the soft rubber tube is adsorbed through the several sets of air holes 212, thereby applying an outward force to the outer arc surface of the soft rubber tube to reduce the pressure on the soft rubber tube when the cutting blade 301 cuts, thereby further avoiding the deformation of the soft rubber tube during the cutting process.

[0023] like Figure 1 and Figure 2 As shown, the cutting mechanism 300 includes a cutting blade 301, a hydraulic push rod 302, and a support frame 303. The support frame 303 is fixedly mounted on the upper surface of the support platform 101. The bottom end of the hydraulic push rod 302 is located on one side of the support frame 303, and the cutting blade 301 is fixedly connected to the working end of the hydraulic push rod 302. Two sets of limiting clamps 202 are located between two sets of support rings 102, and the cutting blade 301 is located between the two sets of limiting clamps 202. The cutting blade 301 does not contact the negative pressure fan 203 and the connecting hose 209. In this embodiment, the cutting blade 301 is positioned between two sets of fixing plates 201, thereby ensuring that when the cutting blade 301 cuts the soft rubber tube, the two limiting clamps 202 and the anti-deformation components can clamp and limit both sides of the cut of the soft rubber tube and prevent deformation. When the hydraulic push rod 302 is activated, the cutting blade 301 descends to cut the soft rubber tube. At this time, the cutting blade 301 will not come into contact with the negative pressure fan 203 and the connecting hose 209, thereby avoiding the connection hose 209 from being cut off and causing the suction force of the air hole 212 to disappear.

[0024] Working principle: The soft rubber tube passes through a set of support rings 102, and then through another set of support rings 102 via four sets of limiting clamps 202. The soft rubber tube is moved to the lower surface of the cutting blade 301. Then, the motor 204 is started to drive the drive gear 207 to rotate. The drive gear 207 drives the driven gear 205 to rotate via the toothed belt 206, thereby driving the two sets of bidirectional screws 211 to rotate. Then, the two sets of limiting clamps 202 clamp and limit the cut of the soft rubber tube on both sides. Then, the negative pressure fan 203 is started. The negative pressure fan 203 is connected to several sets of air holes 212 through the connecting hose 209. The air holes 212 apply an adsorption force to the soft rubber tube. Then, the hydraulic push rod 302 is started to drive the cutting blade 301 to cut the soft rubber tube. At this time, the two ends of the cut of the soft rubber tube are protected by the clamping of the limiting clamps 202 and the adsorption of the air holes 212, which reduces the possibility of displacement, shaking and deformation of the soft rubber tube.

[0025] Note: The bidirectional screw 211 is a special thread structure, the core feature of which is that two sections of threads with opposite directions of rotation are designed on the same screw. This design allows the screw to drive two sliding blocks 210 to move in opposite directions simultaneously when rotating, achieving synchronous symmetrical motion.

[0026] It should be noted that the negative pressure fan 203, motor 204 and hydraulic push rod 302 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the negative pressure fan 203, motor 204 and hydraulic push rod 302 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
