Description

Technical Field

[0001] This application relates to the field of forming machines, and more particularly to a belt forming machine. Background Technology

[0002] Elastic belts can achieve stable tension. In the production process, a forming machine is required. The forming machine is used to attach the backing fabric or adhesive layer to the mold. By rotating the mold, multiple layers of adhesive are applied, thereby forming the belt.

[0003] Currently, Chinese utility model patent CN214688061U discloses a molding machine for forming elastic belts, including a frame and a mold for wrapping adhesive backing. The mold is cylindrical, horizontally arranged, and rotatably mounted on the frame. A mounting rod is slidably mounted on the frame along the radial direction of the mold, and the mounting rod is parallel to the mold. A cutting mechanism is mounted on the mounting rod, and the cutting mechanism is slidably arranged along the axial direction of the mold. A first driving member is mounted on the frame, and the first driving member drives the cutting mechanism to cut the adhesive backing along the axial direction of the mold. This application has the effect of improving the flatness of the cut and making it less prone to skewing.

[0004] When the thickness of the belt to be cut changes, the cutting depth of the cutting mechanism needs to be adjusted to ensure that the cutting mechanism can cut only a single layer of belt. This can easily lead to the belt not being cut or to scratches on the surface of the inner layer of belt. High precision is required, which results in a long adjustment time for the position of the cutting mechanism and low work efficiency. Utility Model Content

[0005] In order to improve work efficiency while ensuring the cutting of single-layer belts, this application provides a belt forming machine.

[0006] This application provides a belt forming machine, which adopts the following technical solution: A belt forming machine includes a forming machine body, a support frame, a cutting assembly, a mounting assembly, and a tensioning assembly. The support frame is mounted on the forming machine body, and the belt to be cut into coils is placed on the support frame. The cutting assembly and the tensioning assembly are both mounted on the forming machine body. The end of the coiled belt passes sequentially around the cutting assembly and the tensioning assembly before being fed into the forming machine body. The mounting assembly includes a release frame, two abutment rollers, a drive roller, and a drive motor. The release frame is located on one side of the coiled belt and is mounted on the forming machine body. The length direction of the abutment rollers is parallel to the axial direction of the coiled belt. The two abutment rollers are distributed vertically and are rotatably connected to the release frame. The drive roller is parallel to the length direction of the abutment rollers and is rotatably connected to the release frame. The drive roller abuts against the surface of the coiled belt. The drive motor drives the drive roller to rotate. The cutting assembly is used to cut the belt between the two abutment rollers.

[0007] By adopting the above technical solution, two abutment rollers distributed in the vertical direction can achieve stable separation of the belt to be cut from the coiled belt: when the coiled belt is conveyed, the end needs to pass between the two abutment rollers. The abutment rollers are parallel to the axis of the coiled belt and are rotatably connected to the release frame. Their positions are fixed and they maintain a certain distance from the coiled belt. This forces the belt to change its conveying direction when passing through the abutment rollers, detaching it from the coiled surface of the coiled belt and forming a straight section to be cut. At the same time, the rotation of the abutment rollers can reduce belt wear and ensure the stability of the belt posture after separation, providing a basis for the precise cutting of the cutting component.

[0008] Optionally, the release frame is slidably connected to the forming machine body in a direction close to or away from the axis of the coiled belt. The forming machine body is provided with a retaining spring, which is used to keep the drive roller on the release frame in contact with the surface of the coiled belt.

[0009] By adopting the above technical solution, the release frame can slide and the drive roller is kept in contact with the belt surface by the holding spring. It can adapt to changes in the diameter of the coiled belt, eliminating the need for frequent manual adjustment of the drive roller position, ensuring continuous conveying and cutting, and improving work efficiency.

[0010] Optionally, the cutting assembly includes a cutting frame, a movable frame, a screw, a drive motor, and a cutter. The cutting frame is mounted on the release frame, the movable frame is slidably connected to the cutting frame along the length of the coiled belt, the screw is rotatably connected to the cutting frame, the movable frame is threadedly connected to the screw, the drive motor is used to drive the screw to rotate, and the cutter is mounted on the movable frame.

[0011] By adopting the above technical solution, the screw-driven moving frame drives the cutter to slide smoothly along the length of the belt, achieving uniform and precise cutting, further ensuring a flat cut, avoiding cutting deviation, and improving the quality of belt cutting.

[0012] Optionally, the cutting frame is slidably connected to the release frame in a direction close to or away from the coiled belt, and the release frame is equipped with a control cylinder for driving the cutting frame to move.

[0013] By adopting the above technical solution, the cutting frame can slide along the direction of approaching or moving away from the coiled belt by controlling the cylinder. During feeding, the control cylinder drives the cutting frame to move away from the coiled belt, which can quickly leave enough operating space. After feeding is completed, the cylinder resets the cutting frame to the appropriate cutting position without affecting subsequent cutting operations, thus balancing the convenience of feeding and the stability of cutting.

[0014] Optionally, the release frame is provided with a support bar, the length direction of which is parallel to the length direction of the coiled belt, and a mating groove is provided on the support bar, which extends along the length direction of the coiled belt and is used to avoid the cutting edge of the cutter.

[0015] By adopting the above technical solution, the support bar is set along the length of the rolled belt, which can provide stable support for the belt section to be cut between the two abutting rollers, avoid the belt from denting or shifting due to cutting force, ensure that the belt posture is straight during cutting, and the groove extends along the length of the belt to accurately avoid the cutting edge of the cutter. This not only prevents the cutter from colliding hard with the support bar, causing damage to the cutting edge or obstruction of cutting, but also limits the cutting path of the cutter.

[0016] Optionally, the movable frame is provided with a through groove, and a limit block is provided at the end of the cutter away from the blade. The blade of the cutter passes through the through groove until the limit block abuts against the movable frame. The limit block is installed on the movable frame by bolts.

[0017] By adopting the above technical solution, the cutter can be quickly disassembled and fixed by the limiting block and bolts, which facilitates the replacement of different types or worn cutters, reduces maintenance difficulty, reduces equipment downtime, and improves operation continuity.

[0018] Optionally, the tensioning assembly includes a tensioning roller, a tensioning frame, and a tensioning spring. The tensioning frame is slidably connected to the forming machine body along the transport direction away from the belt. The tensioning roller is parallel to the length direction of the coiled belt and is rotatably connected to the tensioning frame. The belt passes between the tensioning roller and the tensioning frame and abuts against the surface of the tensioning roller. The tensioning spring is used to ensure that the tensioning frame is away from the transport direction of the belt.

[0019] By adopting the above technical solution, the tension spring drives the tension frame to always keep away from the direction of belt transportation, so that the tension roller continuously and stably presses against the belt, ensuring uniform tension during belt transportation, avoiding belt slack that leads to skewed cutting, and improving cutting consistency.

[0020] Optionally, the support frame is provided with a placement groove that extends vertically. The placement groove is used to place the roller of the rolled belt. The support frame is provided with an anti-detachment block, which is used to block the placement groove. The anti-detachment block is installed on the support frame by bolts.

[0021] By adopting the above technical solution, the placement groove is adapted to the roller shaft of the rolled belt, and the anti-detachment block is sealed by bolts to ensure the stable placement of the belt roll, prevent it from shifting or falling off during the conveying process, ensure smooth belt feeding, and indirectly improve cutting and forming efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The design features a stop roller for positioning, a screw-driven cutter sliding mechanism, and a groove for avoiding obstructions, ensuring a smooth and non-skewed cut. Combined with a control cylinder for rapid adjustment of the cutting frame position, it is suitable for cutting belts of different thicknesses. 2. The spring allows the drive roller to adapt to changes in the belt roll diameter, the tensioning component ensures uniform belt conveying tension, and the quick-release and disassembly structure of the cutter reduces manual adjustment and downtime, improving the equipment's continuous operation capability and maintenance efficiency; 3. The cutting frame can slide to avoid obstacles, making it easy to load the belt roll. The anti-detachment block of the support frame ensures that the belt roll is placed stably. The overall structure simplifies the loading and equipment debugging process. Attached Figure Description
