Abstract
Description
Technical Field
[0001] This utility model relates to the field of woven bag cutting technology, specifically a cutting device for cement woven bag production. Background Technology
[0002] As the primary packaging material for cement products, the demand for cement woven bags is closely related to the development of the construction industry. In the production process of cement woven bags, cutting continuous tubular woven fabric into individual bag blanks to a fixed length is a crucial step. The quality of the cutting directly affects the yield of subsequent printing, bottom sewing, and other processes, as well as the final strength and sealing performance of the cement packaging bags.
[0003] Existing cutting equipment lacks the ability to secure the raw material when cutting cement bags. When the cutting blade contacts and cuts the material, it applies a downward shearing force and a horizontal pushing force. For smooth and soft plastic woven fabric, this force causes the material to move, resulting in the actual cutting position deviating from the preset position. This leads to inconsistent bag blank lengths, severely affecting the yield. Cutting during movement can easily cause skewed or incomplete cuts, and may even damage the warp and weft structure of the woven fabric due to pulling, creating a potential risk of bag breakage. Utility Model Content
[0004] The purpose of this application is to provide a cutting device for cement woven bag production to solve the technical problems existing in the prior art.
[0005] To achieve the above objectives, the technical solution adopted in this application is: to provide a cutting device for cement woven bag production, comprising: a base plate, two side plates fixedly connected to the top of the base plate, an mounting plate fixedly installed between the inner walls of opposite sides of the two side plates, a heat insulation plate provided below the mounting plate, and a cutting blade fixedly installed at the bottom of the heat insulation plate;
[0006] Connecting frames are fixedly installed on opposite sides of the heat insulation plate. Multiple telescopic rods are slidably connected to the connecting frames. Pressure plates are fixedly installed between the bottom ends of the telescopic rods. Washers are fixedly connected to the outside of the telescopic rods. Springs a are sleeved on the outside of the telescopic rods. Springs a are located above the washers. Limiting rings are fixedly installed at the top of each telescopic rod.
[0007] Furthermore, a conveying roller is rotatably connected between the two side plates on opposite sides, and a drive motor is fixedly installed on the side plate. One end of the drive shaft of the drive motor is connected to the rotating shaft of one of the conveying rollers.
[0008] Furthermore, each of the two side plates has a groove on its opposite side near the conveyor roller, and a slider is slidably connected inside the groove.
[0009] Furthermore, a pressure roller is rotatably connected between the two opposing sliders, and a spring b is provided between the top of the slider and the top of the groove.

Detailed Implementation
[0022] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0023] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0024] As attached Figures 1 to 5 The cutting equipment for producing cement woven bags shown includes: a base plate 1, two side plates 11 fixedly connected to the top of the base plate 1, an installation plate 12 fixedly installed between the inner walls of opposite sides of the two side plates 11, a heat insulation plate 13 provided below the installation plate 12, a cutting blade 14 fixedly installed at the bottom of the heat insulation plate 13, and two pneumatic rods 15 fixedly installed at the top of the installation plate 12, with the bottom ends of the output ends of the two pneumatic rods 15 connected to the top of the heat insulation plate 13;
[0025] A connecting frame 2 is fixedly installed on each of the opposite sides of the heat insulation plate 13. Multiple telescopic rods 21 are slidably connected on the connecting frame 2. A pressure plate 22 is fixedly installed between the bottom ends of the telescopic rods 21. A washer 23 is fixedly connected to the outside of the telescopic rods 21. A spring a24 is sleeved on the outside of the telescopic rods 21. The spring a24 is located above the washer 23. A limit ring 25 is fixedly installed at the top of each telescopic rod 21.
[0026] Specifically: When cutting cement woven bags, the output ends of the two pneumatic rods 15 are pushed out, pushing the heat insulation plate 13 and the cutting blade 14 downward. The cutting blade 14 is a hot cutting blade, which cuts the cement woven bag roll. After the cutting is completed, the two pneumatic rods 15 retract, driving the cutting blade 14 back to the initial position.
[0027] When the cutting blade 14 moves downward to cut, it simultaneously drives the connecting frames 2 on both sides to move synchronously, causing the telescopic rod 21 and the pressure plate 22 to move downward. First, the pressure plate 22 presses down the cement woven bag roll. Then, the heat insulation plate 13 continues to move, driving the cutting blade 14 to cut the cement woven bag. When the heat insulation plate 13 continues to move, it drives the connecting frame 2 to move along the outside of the telescopic rod 21. When moving, it squeezes the spring a24, causing the spring a24 to contract and store energy, thereby pressing down both sides of the heat insulation plate 13 at the cutting position to prevent the cement woven bag from moving during cutting.
[0028] In a preferred embodiment, a cutting table 4 is fixedly installed between the inner walls of the two side plates 11 on opposite sides. The top of the cutting table 4 is level with the conveying roller 3. A cutting groove 41 is provided on the cutting table 4, and the cutting groove 41 is opposite to the cutting blade 14.
[0029] Furthermore, the cutting table 4 is used to support the cement woven bag and, together with the pressure plate 22, to press the cement woven bag down. The cutting groove 41 allows the cutting blade 14 to move, thus preventing the cutting blade 14 from having a rigid collision.
[0030] As attached Figures 1 to 5 As shown, a conveying roller 3 is rotatably connected between two opposite sides of the two side plates 11. A drive motor 31 is fixedly installed on the side plate 11. One end of the drive shaft of the drive motor 31 is connected to the rotating shaft of one of the conveying rollers 3. Slide grooves 32 are respectively opened on the opposite sides of the two side plates 11 near the position of the conveying roller 3. A slider 33 is slidably connected inside the slide groove 32. A pressure roller 34 is rotatably connected between two opposite sliders 33. A spring b35 is provided between the top of the slider 33 and the top of the slide groove 32.
[0031] The process involves placing one end of a cement woven bag roll between the conveying roller 3 and the pressing roller 34. The pressing roller 34 presses down the cement woven bag roll to increase friction between the cement woven bag and the conveying roller 3. The pressing roller 34 can be moved upward to adjust its height, causing the slider 33 to move in the chute 32. The spring b35 keeps the pressing roller 34 pressing downward, thus accommodating cement woven bags of different thicknesses. After the drive motor 31 starts, it drives the conveying roller 3 to rotate, causing the conveying roller 3 to move the cement woven bag towards the cutting blade 14. The distance measuring device measures the size of the cement woven bag. Once the required length is reached, the drive motor 31 stops working. After cutting is completed, the drive motor 31 starts working again.
[0032] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
[0033] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
