Description

Technical Field

[0001] This utility model relates to the field of heat cutting devices, specifically a heat cutting device for processing anti-slip woven bags. Background Technology

[0002] Anti-slip woven bags, with their anti-slip textures or coatings, effectively prevent stacking slippage in warehousing and transportation scenarios, and are widely used in chemical, building materials, and agricultural industries. In the processing of anti-slip woven bags, the hot-cutting device is a key piece of equipment for achieving fixed-length cutting. Its positioning accuracy directly affects the subsequent processing quality and performance of the woven bag. A Chinese utility model patent (publication number: CN222538409U) discloses a hot-cutting device for woven bag processing, which not only avoids wrinkling of the woven bag during use and improves the accuracy of hot-cutting, but also enhances the convenience of assembling and disassembling the heating wire.

[0003] However, the above-mentioned device still has some shortcomings in use. Specifically, the position adjustment of the two elastic pressure strips requires manual sliding of the slider and alignment with the scale line. The positioning at both ends relies on manual operation, which is prone to cumulative errors due to visual deviation and uneven operation force. In addition, the clamping force of the elastic pressure strip depends on its own elastic deformation. After long-term use, the elasticity of the pressure strip decreases, which further reduces the positioning reliability. Therefore, a hot cutting device for processing anti-slip woven bags is proposed to address the above issues. Utility Model Content

[0004] To address the problem in existing technologies where the clamping force of elastic pressure strips relies on their own elastic deformation, and the elasticity of the pressure strips diminishes after long-term use, reducing positioning reliability, this utility model proposes a hot-cutting device for processing anti-slip woven bags.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a hot cutting device for processing anti-slip woven bags, including a worktable, a hot cutting mechanism for hot cutting anti-slip woven bags placed on the worktable, a horizontal drive mechanism fixed on the worktable, a mounting frame fixed on the moving end of the horizontal drive mechanism, a cylinder fixed on the top of the mounting frame, and a pressure plate fixed after the telescopic end of the cylinder passes through the mounting frame.

[0006] Connecting blocks are fixed on both sides of the mounting bracket. The connecting blocks are L-shaped. An indicator block is fixed to one end of the connecting block, and a stop block is fixed to the other end of the connecting block. The bottom of the stop block slides in engagement with the top surface of the workbench.

[0007] Preferably, the horizontal drive mechanism includes an electric linear screw module fixed to one end of the top of the worktable, a guide rail fixed to the other end of the top of the worktable, and the two ends of the bottom of the mounting bracket fixed to the sliding ends of the electric linear screw module and the guide rail, respectively.

[0008] Preferably, both ends of the top of the mounting bracket are provided with through holes, and guide rods are fitted into the through holes with clearance. The bottom of the guide rods passes through the through holes and is fixed to the top of the pressure plate.

[0009] Preferably, a perforated hole is provided at the center of the top of the mounting bracket, and the telescopic end of the cylinder protrudes through the perforated hole.

[0010] Preferably, a ruler plate is fixed on both sides of the workbench, and a sliding groove is provided on the ruler plate. One end of the connecting block is slidably engaged with the sliding groove, and the bottom of the indicator block faces the scale line on the ruler plate.

[0011] Preferably, the central axis of the indicator block and the side of the stop block near the support frame are on the same plane.

[0012] Preferably, a support frame is fixed to the top of the workbench, and the hot cutting mechanism is mounted on the support frame.

[0013] Preferably, a rubber pad is fixed to the bottom of the pressure plate, and the rubber pad has anti-slip texture.

[0014] The advantages of this utility model are: 1. This utility model, through the structural design of a horizontal drive mechanism, mounting frame, cylinder and pressure plate, allows the position of the pressure plate to be adjusted according to the processing requirements of the anti-slip plastic bag during use. The positioning of the anti-slip plastic bag can be completed by the descent of the pressure plate, ensuring the stability of the anti-slip plastic bag during hot cutting. It can form a uniform constraint on the woven bag as a whole, effectively suppressing the wrinkle displacement caused by thermal expansion and contraction, thereby improving the hot cutting quality. 2. This utility model, through the structural design of connecting blocks, indicator blocks and stop blocks, and the way the stop blocks fit and limit the end of the woven bag, directly uses the side of the baffle as a reference, so that the position of the woven bag after placement is uniform, eliminating the need for repeated manual adjustments and reducing the labor intensity of operators.

[0019] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses a hot-cutting device for processing anti-slip woven bags. (Refer to...) Figure 1 , Figure 2 and Figure 3 and Figure 4 A hot cutting device for processing anti-slip woven bags includes a workbench 1, a support frame 2 fixed on the top of the workbench 1, and a hot cutting mechanism 20 for hot cutting the anti-slip woven bags placed on the workbench 1. The composition and structure of the hot cutting mechanism 20 are the same as those in the prior art (announcement number: CN222538409U), and will not be described in detail here.

[0020] A horizontal drive mechanism 3 is fixed on the workbench 1. A mounting bracket 4 is fixed on the moving end of the horizontal drive mechanism 3. A cylinder 5 is fixed on the top of the mounting bracket 4. A pressure plate 6 is fixed after the telescopic end of the cylinder 5 passes through the mounting bracket 4.

[0021] Connecting blocks 9 are fixed on both sides of the mounting bracket 4. The connecting blocks 9 are "L" shaped. An indicator block 90 is fixed to one end of the connecting block 9, and a stop block 91 is fixed to the other end of the connecting block 9. The bottom of the stop block 91 slides with the top surface of the workbench 1.

[0022] Reference Figure 1 , Figure 2 and Figure 3 The horizontal drive mechanism 3 includes an electric linear screw module 30 fixed to one end of the top of the worktable 1, and a guide rail 31 fixed to the other end of the top of the worktable 1. The two ends of the bottom of the mounting bracket 4 are respectively fixed to the sliding ends of the electric linear screw module 30 and the guide rail 31.

[0023] Among them, the electric linear screw module 30 adopts a closed-loop servo motor + ball screw transmission, with a repeatability positioning accuracy of ±0.05mm. It can receive cutting length parameters through the control system (such as PLC) and automatically drive the mounting frame 4 to move along the guide rail 31, replacing the manual operation of loosening / tightening bolts and realizing the automatic adjustment of positioning distance.

[0024] The guide rail 31 uses a linear slide rail and a wear-resistant slider.

[0025] Reference Figure 2 and Figure 3 Both ends of the top of the mounting bracket 4 are provided with through holes, and guide rods 7 are fitted into the through holes with clearance. The bottom of the guide rods 7 passes through the through holes and is fixed to the top of the pressure plate 6. The guide rods 7 ensure that the pressure plate 6 can be raised and lowered vertically to prevent tilting and uneven pressing.

[0026] Reference Figure 2 , Figure 3 and Figure 4 A perforated hole is provided in the center of the top of the mounting bracket 4, through which the telescopic end of the cylinder 5 passes.

[0027] Reference Figure 1 , Figure 2 and Figure 3 and Figure 4 Both sides of the workbench 1 are fixed with ruler plates 8, and the ruler plates 8 have sliding grooves 80. One end of the connecting block 9 slides in the sliding groove 80. The bottom of the indicator block 90 faces the scale line on the ruler plate 8, and the central axis of the indicator block 90 and the side of the stop block 91 near the support frame 2 are on the same plane. Both the indicator block 90 and the stop block 91 are made of transparent acrylic.

[0028] Among them, the ruler plate 8 has several scale lines equidistantly arranged along its horizontal direction.

[0029] Reference Figure 3 and Figure 4 A rubber pad is fixed to the bottom of the pressure plate 6. The rubber pad has anti-slip texture. The rubber pad is made of nitrile rubber with a Shore hardness of 75A. The surface is processed with diamond anti-slip texture to increase the static friction coefficient with the anti-slip woven bag and prevent slippage during hot cutting.

[0030] Working principle: In use, first connect the external power supply and switch to the electrical equipment in this device. Based on the required hot-cut length, turn on the switch of the electric linear screw module 30. The electric linear screw module 30, in conjunction with the guide rail 31, drives the mounting frame 4 to move, thereby adjusting the position of the connecting block 9. The distance moved can be visually understood through the scale on the ruler 8, allowing for precise control of the required adjustment position. Once the desired processing position is reached, turn off the switch of the electric linear screw module 30. Place the anti-slip woven bag from the workbench 1, with one end of the anti-slip woven bag against the side of the stop block 91 to ensure uniform positioning. Then, turn on the switch of the cylinder 5. The cylinder 5 drives the pressure plate 6 to descend and position the placed anti-slip plastic bag. The hot-cutting mechanism 20 then performs hot-cutting on the positioned anti-slip plastic bag. The specific operation process is the same as existing technology and will not be elaborated further here.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
