Description

Technical Field

[0001] This utility model relates to the field of wear-resistant mesh belt production technology, specifically a cutting machine for the production of wear-resistant mesh belts. Background Technology

[0002] Wear-resistant mesh belts (such as polyester mesh) are widely used in drying, filtration and other fields due to their excellent properties such as high strength, wear resistance, corrosion resistance and high temperature resistance. In the production process of wear-resistant mesh belts, in order to obtain a mesh belt of a suitable length, it is usually necessary to use a cutting machine to cut the produced wear-resistant mesh belt.

[0003] When existing cutting machines are in use, the rotating roller is driven to rotate and transport the belt by the friction between the rotating roller and the mesh belt. Then, the heated heat-sealing blade moves down to melt the mesh belt (polyester mesh) material and achieve cutting. The edges are fused simultaneously during cutting to prevent the mesh belt (polyester mesh) material from loosening or fraying.

[0004] Existing cutting machines have the following problems: during the process of conveying the mesh belt through the friction between the rotating roller and the mesh belt, wrinkles may appear on the surface of the mesh belt, causing the mesh belt to jam during the conveying process and affecting the normal operation of the mesh belt cutting work. To address this, we propose a cutting machine for producing wear-resistant mesh belts. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a cutting machine for producing wear-resistant mesh belts. By using a flattening mechanism to flatten the surface of the mesh belt during transportation, the cutting process is prevented from being stuck due to wrinkles in the mesh belt, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting machine for producing wear-resistant mesh belts, including a processing table, an adjustable heat-sealing tool on the left side of the upper surface of the processing table, and a flattening mechanism;

[0007] Flattening mechanism: It includes a reciprocating lead screw, a support frame, a slide groove, an adjusting frame, a rotating shaft, a flattening roller, an adjusting assembly, and a driving assembly. The reciprocating lead screw is rotatably connected to the protective cover on the rear side of the processing table through the driving assembly. The outer surface of the reciprocating lead screw is slidably connected to the support frame through a crescent lock. The upper end of the support frame has slide grooves on both the front and rear sides. An adjusting frame is slidably connected between the two slide grooves through the adjusting assembly. The flattening roller is rotatably connected to the inside of the support frame and the adjusting frame through a rotating shaft. The flattening mechanism flattens the surface of the conveyor belt during the transportation process, avoiding the occurrence of jamming in the cutting process due to wrinkles in the conveyor belt.

[0008] Furthermore, the adjustment assembly includes a limiting rod, a lead screw, and a turntable. The limiting rod is provided in the rear slide groove, and the outer surface of the limiting rod is slidably connected to the slide hole on the rear side of the adjustment frame. The lead screw is rotatably connected in the front slide groove, and the outer surface of the lead screw is threadedly connected to the threaded hole on the front side of the adjustment frame. The upper end of the lead screw is provided with a turntable to facilitate the adjustment of the height of the upper flattening roller.

[0009] Furthermore, it also includes a microcontroller, which is located on the front side of the upper surface of the processing table. The input end of the microcontroller is electrically connected to an external power supply, and the input end of the heat sealing tool is electrically connected to the output end of the microcontroller, which facilitates the normal operation of the equipment.

[0010] Furthermore, slots are provided on both the front and rear sides of the left end of the upper surface of the processing table, and a bracket is slidably connected between the two slots. Rotating rollers are rotatably connected inside the processing table and the bracket through rotating rods. The two rotating rollers are vertically aligned to facilitate the transport of the conveyor belt.

[0011] Furthermore, the processing table is equipped with a motor inside, the rear end of the motor's output shaft is fixedly connected to the front end of the rotating rod on the lower side, and the input end of the motor is electrically connected to the output end of the microcontroller to provide driving force.

[0012] Furthermore, the drive assembly includes a first bevel gear and a second bevel gear. The second bevel gear is provided at the rear end of the lower rotating rod, and the first bevel gear is fixedly sleeved on the left end of the outer surface of the reciprocating screw. The first bevel gear and the second bevel gear mesh with each other to facilitate the normal operation of the flattening mechanism.

[0013] Furthermore, an electric push rod is provided in the mounting groove on the left side of the upper surface of the processing table. A fixing plate is provided at the lower end of the telescopic rod of the electric push rod. A heat sealing tool is provided on the lower surface of the fixing plate. The input end of the electric push rod is electrically connected to the output end of the microcontroller, which facilitates the control of the movement of the heat sealing tool.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The cutting machine produced by this wear-resistant mesh belt has the following advantages:

[0015] The rotating turntable drives the lead screw to rotate, and the adjusting frame drives the upper pressing roller to move downwards through the rotating shaft until the outer surfaces of the two pressing rollers contact the upper and lower sides of the mesh belt respectively. During the conveying process of the mesh belt, the reciprocating lead screw is driven to rotate through the second bevel gear and the meshing bevel gear one, causing the support frame to slide back and forth. The support frame drives the two vertically adjacent smooth pressing rollers to move back and forth, pressing the surface of the mesh belt flat during the conveying process, thus avoiding the occurrence of jamming in the cutting process due to wrinkles in the mesh belt.

[0022] 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.

[0023] Please see Figure 1-5This embodiment provides a technical solution: a cutting machine for producing wear-resistant mesh belts, including a processing table 1, an adjustable heat-sealing cutter 12 on the left side of the upper surface of the processing table 1, a flattening mechanism 3, and a microcontroller 2. The microcontroller 2 is located on the front side of the upper surface of the processing table 1, with its input end electrically connected to an external power source and its input end electrically connected to the output end of the microcontroller 2. (The heat-sealing cutter 12 consists of a cutter body, a placement groove inside the cutter body, and an electric heating wire inside the placement groove; the input end of the electric heating wire is electrically connected to the output end of the microcontroller 2.) Grooves 5 are provided on both the front and rear sides of the left end of the upper surface of the processing table 1, and a bracket 6 is slidably connected between the two grooves 5. (The processing table and the bracket 6 are connected by bolts.) The bolts are threadedly connected to the rear side of the bracket 6 and fixed by tightening the rear side of the processing table 1. To adjust the distance between two vertically adjacent rotating rollers 8, loosen the bolts and pull the bracket 6. Both the processing table 1 and the bracket 6 are internally connected to rotating rollers 8 via rotating rods 7. (A rotary encoder is mounted on the lower rotating rod 7. The output of the rotary encoder is electrically connected to the input of the microcontroller 2. When the conveyor belt passes through, the encoder rotates with the rotating rod 7, generating pulse signals, which are transmitted to the microcontroller 2. The microcontroller 2 calculates the distance the belt moves based on the number of pulses (number of pulses × length corresponding to a single pulse). When the preset length is reached, cutting is triggered by the microcontroller 2.) The two rotating rollers 8 are vertically aligned, and the processing table 1... An internal motor 9 is installed. The rear end of the output shaft of the motor 9 is fixedly connected to the front end of the rotating rod 7 on the lower side. The input end of the motor 9 is electrically connected to the output end of the microcontroller 2. An electric push rod 10 is installed in the mounting groove on the left side of the upper surface of the processing table 1. A fixing plate 11 is installed at the lower end of the telescopic rod of the electric push rod 10. A heat sealing tool 12 is installed on the lower surface of the fixing plate 11. The input end of the electric push rod 10 is electrically connected to the output end of the microcontroller 2. (A guide roller and a unwinding roller are rotatably connected to the rear side of the upper surface of the processing table 1. Bearings are installed at both ends of the outer surface of the unwinding roller's rotating rod. The bearings are fixed in the bearing seat by bearing end caps and bolts. The bearing seat is located on the rear side of the upper surface of the processing table 1. During installation, the bearing of the unwinding roller's rotating rod is placed on the upper end of the bearing seat, and then...) Bolts are used to install the bearing end cover, allowing the bearing housing and bearing end cover to form a support platform for the bearing. The operator guides the mesh belt from the unwinding roller over the bottom of the guide roller, then through the space between the two flattening rollers 36, and finally between the two rotating rollers 8. The distance between the two rotating rollers 8 is adjusted so that their outer surfaces contact the upper and lower sides of the mesh belt. Controlled by the microcontroller 2, the motor 9 drives the lower rotating roller 8 to rotate via the rotating rod 7. Friction causes the mesh belt to move from right to left. As the mesh belt passes, the encoder generates a pulse signal as the rotating rod 7 rotates, transmitting the signal to the microcontroller 2. When the preset length is reached, the motor 9 stops operating, and the electric heating wire heats the heat-sealing cutter 12.The telescopic rod of the electric push rod 10 drives the heated heat-sealing cutter 12 downwards via the fixed plate 11, melting the mesh belt (polyester mesh) material to achieve cutting. During cutting, the edges are simultaneously fused to prevent the mesh belt (polyester mesh) material from loosening or fraying. After cutting, the operation is repeated to continue cutting the mesh belt. When the mesh belt on the unwinding roller is used up, the bolts are unscrewed to remove the bearing end cover, and then the unwinding roller can be removed to replace the new mesh belt. After reinstalling the unwinding roller, the above operation is repeated on the end of the mesh belt to continue the sealing work.

[0024] Flattening mechanism 3 includes a reciprocating screw 31, a support frame 32, a slide groove 33, an adjusting frame 34, a rotating shaft 35, a flattening roller 36, an adjusting assembly 37, and a drive assembly 38. The reciprocating screw 31 is rotatably connected to the protective cover 4 on the rear side of the processing table 1 via the drive assembly 38. The outer surface of the reciprocating screw 31 is slidably connected to the support frame 32 via a crescent lock. Slide grooves 33 are provided on both the front and rear sides of the upper end of the support frame 32. An adjusting frame 34 is slidably connected between the two slide grooves 33 via the adjusting assembly 37. Flattening rollers 36 are rotatably connected inside the support frame 32 and the adjusting frame 34 via rotating shafts 35. 6. (The flattening roller 36 is a smooth stainless steel roller). The adjusting assembly 37 includes a limiting rod 371, a lead screw 372, and a turntable 373. The limiting rod 371 is provided in the rear slide groove 33. The outer surface of the limiting rod 371 is slidably connected to the slide hole on the rear side of the adjusting frame 34. The lead screw 372 is rotatably connected in the front slide groove 33. The outer surface of the lead screw 372 is threadedly connected to the threaded hole on the front side of the adjusting frame 34. (The exposed parts of the outer surfaces of the reciprocating lead screw 31 and the lead screw 372 are provided with bellows. The bellows are fixedly connected to the side of the support frame 32, the side of the protective cover 4, and the side of the front slide groove 33, respectively.) Between the side of the support frame 32 and the side of the adjusting frame 34, the bellows contracts or extends as the support frame 32 or the adjusting frame 34 moves, ensuring the sealing and lubrication of the reciprocating screw 31 and screw 372. The upper end of the screw 372 is provided with a turntable 373. The drive assembly 38 includes a first bevel gear 381 and a second bevel gear 382. The rear end of the lower rotating rod 7 is provided with the second bevel gear 382. The left end of the outer surface of the reciprocating screw 31 is fixedly sleeved with the first bevel gear 381. The first bevel gear 381 and the second bevel gear 382 are meshed and connected. Then, rotating the turntable 373 drives the screw 372 to rotate. Under the restriction of the limiting rod 371, the screw 372 rotates. The rotation of the lead screw 372 drives the threaded adjustment frame 34 to move downward along the slide groove 33, causing the upper rotating shaft 35 to drive the upper flattening roller 36 to move downward until the outer surfaces of the two flattening rollers 36 contact the upper and lower sides of the mesh belt respectively. During the conveying process of the mesh belt, the rotation of the lower rotating rod 7 drives the second bevel gear 382 to rotate, which drives the reciprocating lead screw 31 to rotate through the meshing bevel gear 381, causing the support frame 32 to slide back and forth. The support frame 32 drives the two vertically adjacent flattening rollers 36 to move back and forth through the adjustment frame 34, flattening the mesh belt during the conveying process.

[0025] The working principle of the cutting machine for producing wear-resistant mesh belts provided by this utility model is as follows: The operator loads the mesh belt from the unwinding roller, passes it under the guide roller, then through the space between two flattening rollers 36, and finally through the space between two rotating rollers 8. The turntable 373 then rotates, driving the lead screw 372 to rotate. Under the constraint of the limiting rod 371, the rotation of the lead screw 372 causes the threaded adjusting bracket 34 to move downwards along the slide groove 33, causing the upper rotating shaft 35 to drive the upper flattening rollers 36 downwards until the outer surfaces of the two flattening rollers 36 contact the upper and lower sides of the mesh belt. The distance between the two rotating rollers 8 is then adjusted so that the outer surfaces of the two rotating rollers 8 contact the upper and lower sides of the mesh belt. Through the control of the microcontroller 2, the motor 9 drives the lower rotating roller 8 to rotate via the rotating rod 7. Friction causes the mesh belt to move from right to left. When the mesh belt passes through, the encoder generates a pulse signal as the rotating rod 7 rotates, transmitting the signal to the microcontroller 2 to achieve the preset length. When the temperature is reached, the motor 9 stops working through the control of the microcontroller 2, the electric heating wire heats the heat sealing cutter 12, and the telescopic rod of the electric push rod 10 drives the heated heat sealing cutter 12 to move downward through the fixed plate 11, melting the mesh belt (polyester mesh) material to achieve cutting. During cutting, the edges are simultaneously fused to prevent the mesh belt (polyester mesh) material from loosening or fraying. After cutting, the operation is repeated to continue cutting the mesh belt. During the transportation of the mesh belt, the rotation of the lower rotating rod 7 drives the second bevel gear 382 to rotate, which drives the reciprocating screw 31 to rotate through the meshing bevel gear 381, causing the support frame 32 to slide back and forth. The support frame 32 drives the two vertically adjacent flattening rollers 36 to move back and forth through the adjusting frame 34 to flatten the mesh belt during transportation. When the mesh belt on the unwinding roller is used up, the bolts are unscrewed to remove the bearing end cover, and then the unwinding roller can be removed to replace the new mesh belt. After the unwinding roller is reinstalled, the above operation is repeated on the end of the mesh belt to continue the sealing work.

[0026] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be a PIC10F200, the motor 9 can be a 1TL0003 series, and the microcontroller 2 controls the operation of the motor 9, the electric push rod 10 and the heat sealing tool 12 using methods commonly used in the prior art.
