Description

Technical Field

[0001] This utility model belongs to the field of fiber sealing gasket production technology, specifically relating to a shearing device for fiber sealing gasket production. Background Technology

[0002] A shearing device is needed during the remanufacturing of fiber sealant to cut the fiber sealant off from the whole piece of fiber material.

[0003] Existing shearing devices typically consist of two concentric circular cutters of different sizes. The cutters are pressed onto the fiber material by a hydraulic device, at which point the cutters cut the fiber sealing gasket from the fiber material. The cut fiber sealing gasket gets stuck in the annular groove between the two cutters. When the cutter performs the next shearing operation, the fiber sealing gasket in the annular groove may fall onto the uncut fiber material. During the shearing process, the fiber sealing gasket that has fallen onto the fiber material will be sheared again, causing damage and scrapping of the fiber sealing gasket, which greatly increases the scrap rate of the fiber sealing gasket. Utility Model Content

[0004] The purpose of this invention is to provide a shearing device for producing fiber sealing gaskets, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shearing device for producing fiber sealing gaskets, comprising: a device body, wherein the device body is provided with a conveying channel for conveying fiber materials, and a lifting mechanism, a mounting plate and a cutter body are sequentially installed downward above the conveying channel. The cutter body includes a first circular cutter and a second circular cutter connected to the same center, and an annular gap for unloading is formed between the first circular cutter and the second circular cutter. A liftable unloading ring seat is provided in the annular gap, and the unloading ring seat lifts and lowers to disengage the fiber sealing gasket from the annular gap.

[0006] Preferably, the mounting plate is provided with a movable plate connected to the top of the feeding ring seat, and an adjustment mechanism for adjusting the lifting force is provided between the movable plate and the mounting plate. The mounting plate has a second through hole for the feeding ring seat to pass through.

[0007] Preferably, the adjusting mechanism includes at least a countersunk bolt and a spring. A first through hole and a threaded hole are sequentially passed between the movable plate and the mounting plate. One end of the countersunk bolt passes through the first through hole and the other end is inserted into the threaded hole. The spring is sleeved on the countersunk bolt, and both ends of the spring abut against the countersunk heads on the movable plate and the countersunk bolt, respectively.

Detailed Implementation

[0020] 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.

[0021] refer to Figure 1-3 As shown, the present invention provides a shearing device for producing fiber sealing gaskets, comprising: a device body, a conveying channel for conveying fiber materials on the device body, a lifting mechanism, a mounting plate 9 and a cutting tool body installed sequentially downward above the conveying channel, the cutting tool body including a first circular cutting tool 10 and a second circular cutting tool 16 connected to the same center, an annular gap for unloading is formed between the first circular cutting tool 10 and the second circular cutting tool 16, and a lifting unloading ring seat 11 is provided in the annular gap, the unloading ring seat 11 being lifted to disengage the fiber sealing gasket from the annular gap.

[0022] Combination Figure 3-5 As shown, connecting blocks 15 for connection are provided around the first circular cutter 10 and the second circular cutter 16. Lifting grooves 12 for accommodating connecting blocks 15 are longitudinally opened around the bottom of the feeding ring seat 11. The four connecting blocks 15 are respectively arranged in the lifting grooves 12 in the same direction.

[0023] As described above, using the equipment body, lifting mechanism, mounting, and cutter body provided by this utility model, the fiber material can be sequentially and intermittently conveyed to the area below the cutter body through the conveying channel. At this time, the lifting mechanism is activated, driving the mounting plate 9 to descend, thereby causing the first circular cutter 10 and the second circular cutter 16 to press onto the fiber material. At this time, the cut fiber sealing gasket is in the annular gap. When the cutter body is reset, the feeding ring seat 11 descends in the annular gap, which facilitates the feeding of the fiber sealing gasket stuck in the annular gap. The top of the first circular cutter 10 is welded to the bottom of the mounting plate 9. The second circular cutter 16 is installed on the coaxial center of the inner side of the first circular cutter 10 through multiple connecting blocks 15. The lifting groove 12 avoids interference of the connecting blocks 15 with the lifting of the feeding ring seat 11.

[0024] In this utility model, combined with Figure 2-3 As shown, the mounting plate 9 of this embodiment is provided with a movable plate 8 connected to the top of the feeding ring seat 11. An adjustment mechanism for adjusting the lifting force is provided between the movable plate 8 and the mounting plate 9. A second through hole 17 for the feeding ring seat 11 to pass through is provided on the mounting plate 9.

[0025] Combination Figure 2-3 As shown, the adjustment mechanism includes at least one countersunk bolt 5 and a spring 6. A first through hole 13 and a threaded hole 14 are sequentially passed between the movable plate 8 and the mounting plate 9. One end of the countersunk bolt 5 is movably passed through the first through hole 13, and the other end of the countersunk bolt 5 is inserted into the threaded hole 14. The spring 6 is sleeved on the countersunk bolt 5, and the two ends of the spring 6 abut against the countersunk heads on the movable plate 8 and the countersunk bolt 5, respectively.

[0026] As described above, using the movable plate 8 provided by this utility model, the movable plate 8 provides an installation position for the adjustment mechanism and the feeding ring seat 11. When the feeding ring seat 11 is not under force, the bottom end of the feeding ring seat 11 is set below the cutter body. When the mounting plate 9 descends, the feeding ring seat 11 first abuts against the fiber material, thereby pre-pressing the fiber material. When the cutter body cuts the fiber material, the movable plate 8 rises on the countersunk bolt 5 and compresses the spring 6. When the cutter body rises and resets, the elastic force of the spring 6 is released, thereby driving the movable plate 8 to descend on the countersunk bolt 5, and then driving the feeding ring seat 11 to descend and reset in the annular gap in the cutter body. During this process, it is convenient to discharge the fiber sealing gasket stuck in the annular gap in time. The countersunk bolt 5 can be removed from the threaded hole 14, and the spring 6 can be replaced at this time.

[0027] In this utility model, combined with Figure 1-3 As shown, the lifting mechanism of this embodiment includes a gantry frame 2 and a hydraulic cylinder 3 installed on the top of the gantry frame 2. The telescopic end of the hydraulic cylinder 3 is provided with a pressing rod 7 connected to the mounting plate 9, and the movable plate 8 is sleeved on the pressing rod 7.

[0028] Combination Figure 2 As shown, the equipment body includes an operating table 1 and a conveyor belt 4 installed on the top of the operating table 1. A conveying channel is formed on the top surface of the conveyor belt 4. A gantry frame 2 is installed on the top of the operating table 1, and the conveyor belt 4 is installed through the gantry frame 2 and the operating table 1.

[0029] As described above, in the lifting mechanism and equipment body provided by this utility model, the operating table 1 in the equipment body provides an installation position for the conveyor belt 4, and the gantry 2 provides an installation position for the hydraulic cylinder 3. The cross-section of the operating table 1 is a U-shaped structure, and the conveyor belt 4 is installed in the U-shaped structure. The fiber material can be intermittently conveyed to the bottom of the cutter body through the conveyor belt 4. The hydraulic cylinder 3 can drive the pressing rod 7 and the mounting plate 9 to press down, thereby pressing the cutter body onto the fiber material, which facilitates the cutting of the fiber material by the cutter body.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
