Description

Technical Field

[0001] This utility model relates to the slitting of defective film products, specifically a slitting device for defective film products. Background Technology

[0002] In tire factories and rubber product factories, rubber products are often composed of different types of rubber composites according to product functional requirements. These composite products have high requirements for parameters such as the ratio, width, and thickness of the composite rubber compounds. Production lines producing these composite products generate a certain amount of defective products during both the initial startup phase and the final stages of production. These defective composite products cannot be used in the next process. If these defective composite rubber products are not slit and are directly mixed into the raw materials for a new round of production, the properties of the raw materials will be affected to some extent due to the presence of other rubber compounds mixed in. Composite products often contain high-performance, high-cost raw materials; reusing them directly as low-grade materials without slitting is also detrimental to cost control.

[0003] To ensure product quality and performance while effectively controlling costs, defective composite rubber products generated before and after production must be slit according to the type of rubber compound before reuse. Currently, there are two main methods for slitting defective products: manual slitting and machine slitting. Most manufacturers primarily use manual slitting, where workers manually hold a cutting blade to slit the products. Manual slitting is inefficient, labor-intensive, and the cutting blade can easily injure operators. Utility Model Content

Figure 3 These are partial schematic diagrams of the clamping and conveying assembly and the module conveying assembly. Figure 4 yes Figure 3 Side view; Figure 5 This is a schematic diagram of the pressure plate assembly;

[0028] like Figure 3 As shown, the module conveying assembly 1 includes multiple module conveyor belts 11, with two adjacent module conveyor belts 11 forming a first gap 110. The clamping conveying assembly 2 includes multiple clamping conveyor belts 21, with two adjacent clamping conveyor belts 21 forming a second gap 210. The multiple module conveyor belts 11 are located below the multiple clamping conveyor belts 21. A conveying channel is formed between the multiple module conveyor belts 11 and the multiple clamping conveyor belts 21. The conveying channel is used to convey film. The second gap 210 is aligned with the first gap 110. The cutter of the cutter assembly 24 is disposed in the gap for cutting the film in the conveying channel.

[0029] Multiple modular conveyor belts 11 provide linear transport, enabling basic transport of products. Multiple clamping conveyor belts 21 form a triangular structure, with the lower side of the triangle serving as the working surface. This allows for clamping and transporting of the products to be cut, ensuring smooth completion of the cutting process.

[0030] like Figure 4 As shown, the cutting assembly 24 includes a circular cutter 240 and a straight cutter 241. The circular cutter 240 is fitted with a cutter holder 242, which is positioned below the multiple modular conveyor belts 11. The circular cutter 240 and the straight cutter 241 are located one after the other on the same cutting line. Both the circular cutter 240 and the straight cutter 241 are mounted on a cutting block (not shown), and the cutter holder 242 is mounted on a bracket (not shown). The cutting block and the bracket are both located within the triangular space of the multiple modular conveyor belts 11 and are mounted on the frame.

[0031] The cutting assembly consists of two sets of cutting blades, which can operate independently or simultaneously. When processing a single product, only one set of blades needs to be used; when processing two products, both sets are used simultaneously. Each set of blades includes a rotary cutter and a straight cutter. The rotary cutter is positioned at the front to perform a rotary cut on the product, while the straight cutter is positioned at the rear to perform a secondary cut. The cutting blades are equipped with a heating function; heating the blades makes cutting even easier.

[0032] like Figure 2 and Figure 5 As shown, the clamping conveyor assembly 2 is further provided with an adjusting clamping assembly 22, including an adjusting pressure plate 220. The adjusting pressure plate 220 is located above the clamping surfaces of the multiple clamping conveyor belts 21. The adjusting pressure plate 220 has multiple through holes 221 aligned with multiple second gaps 210. Both ends of the adjusting pressure plate 220 are provided with adjusting screws 222, adjusting springs 223, and adjusting nuts 224. The lower end of the adjusting screw 222 is fixed to the adjusting base plate, and the upper end is fitted with the adjusting spring 223 and tightened with the adjusting nut 224. The adjusting base plate is mounted on the frame. When the height of the clamping surfaces of the multiple clamping conveyor belts 21 changes, or when the thickness of the film changes, the height of the adjusting pressure plate 220 can be quickly adjusted by adjusting the adjusting nut 224. The adjusting spring 223 also provides a certain amount of cushioning.

[0033] like Figure 2 and Figure 5As shown, the clamping conveyor assembly 2 is also provided with an auxiliary clamping assembly 23, which includes a non-powered roller 231, an auxiliary pressure plate 230, and a non-powered roller 231 arranged in parallel and sequentially. The auxiliary pressure plate 230 is located above the clamping surface of the multiple clamping conveyor belts 21. Both ends of the auxiliary pressure plate 230 are provided with a hinge seat 232, a connecting rod 233, a hinge block 234, and a fixing plate 235. The hinge seat 232 is fixed to the end of the auxiliary pressure plate 230. One end of the connecting rod 233 is hinged to the hinge seat 232, and the other end is hinged to the hinge block 234. The other end of the hinge block 234 is hinged to the fixing plate 235. Through the action of hinges and connecting rods, the auxiliary pressure plate 230 and the unpowered roller 231 press against the pressing surfaces of the multiple clamping conveyor belts 21 under their own weight. The fixed plate 235 is connected to the height adjustment component 25, which is connected to the frame. The fixed plate 235 can adjust its own height according to the height adjustment component 25.

[0034] like Figure 2 As shown, the clamping conveyor assembly 2 is further equipped with a height adjustment assembly 25 for adjusting the height of the multiple clamping conveyor belts 21 to change the height of the conveying channel. The height adjustment assembly 25 includes an outer frame 251, a slide rail 252, a slider 253, a height adjustment stud 254, and a fastening nut 255. The outer frame 251 is fixed to the machine frame, the slide rail 252 is fixed to the outer wall of the outer frame 251, the slider 253 is connected to the slide rail 252 and can move up and down, the slider 253 is also connected to the drive shaft of the multiple clamping conveyor belts 21, the height adjustment stud 254 is fixed to the upper part of the slider 253 and passes through the outer frame 251, and the fastening nut 255 fastens the height adjustment stud 254 to the outer frame 251. When cutting different film thicknesses, adjusting the height adjustment stud 254 can quickly change the thickness.

[0035] The multiple clamping conveyor belts 21 are equipped with one active roller, one passive roller, and one tensioning roller. The active roller has a drive shaft connected to a gear and is driven by a motor and chain. The tensioning roller is located at the top.

[0036] The end of the module conveying component 1 is also provided with a roller conveyor component 3 for outputting the cut film. The roller conveyor component is used to convey one of the cut pieces of film, so that the cut products can be stacked separately according to category.

[0037] This utility model's modular conveyor belt consists of three modular conveyor belts (left, center, and right), with a gap between each two belts. This gap is designed to allow for the passage of the cutting blades. With two gaps between the three conveyor belts, two cutting blades can be installed, allowing for the simultaneous cutting of two defective products.

[0038] The clamping conveyor belt is positioned above the modular conveyor belt and also consists of three modular conveyor belts (left, center, and right). The width of the three modular conveyor belts on the clamping conveyor belt is the same as the width of the modular conveyor belt below. The clamping conveyor belt also has two gaps, which are aligned with the gaps in the lower modular conveyor belt. The clamping conveyor belt is vertically adjustable, creating a conveying channel space of a certain height between it and the lower conveyor belt. A pressing component with a downward pressure elasticity is located in the middle of the clamping conveyor belt, which compresses and conveys the passing film. The pressing component automatically adjusts its height according to the thickness of the passing film under the action of the elastic component. Under the clamping and conveying action of the clamping conveyor and the lower conveyor belt, defective products are cut into two strips (left and right) by the cutting component.

[0039] The roller conveyor assembly is located behind the slitting conveyor, which is used to transport one of the slitting strips of rubber material. This allows the slitting rubber material to be stacked separately.

[0040] The cutting assembly is installed inside the clamping conveyor belt, with the cutter aligned with the belt gap. The cutter inserts into the belt gap and completes the cutting and segmentation. The cutting assembly consists of two groups, left and right, each with one disc cutter and one straight cutter. The disc cutter is positioned at the front to perform a rolling cut on the rubber material. The disc cutter only needs to complete more than 80% of the cutting; any uncut material can be finally segmented by the straight cutter behind the disc cutter. The blades on the cutting assembly have a heating function; the heated blades can more easily segment the product.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
