Description

Technical Field

[0001] This utility model relates to the field of coal mine conveying, specifically a cutting device for flame-retardant conveyor belts with fabric cores in coal mines. Background Technology

[0002] Fabric core flame retardant conveyor belts are made by impregnating and plasticizing or vulcanizing an integral belt core with polyvinyl chloride impregnation paste. They are characterized by high strength, large carrying capacity, and balanced transportation. At the same time, this product has good flame retardant, antistatic, impact resistance, wear resistance, and corrosion resistance properties. Fabric core flame retardant conveyor belts are mainly suitable for underground transportation in coal mines, and can also be used for material transportation in the metallurgical and chemical industries.

[0003] Existing fabric-core flame-retardant conveyor belts may require different specifications to cope with different coal mine environments and working conditions. Therefore, cutting them allows for flexible adjustment of the conveyor belt size to adapt to different work needs. The current cutting method involves unfolding the conveyor belt to a certain length, then placing it on a cutting platform and using a drive assembly to move the cutting blade to one side for cutting. During this process, the fabric-core flame-retardant conveyor belt will shift its position as the cutting blade moves, which will affect the overall cutting accuracy. Furthermore, due to the high strength of the fabric-core flame-retardant conveyor belt, the cutting blade is prone to jamming during flat cutting.

[0004] In summary, the aforementioned structure will shift in position during the actual cutting process, which will affect the overall cutting accuracy, and the cutting blade is very prone to jamming during flat cutting. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a coal mine fabric core flame retardant conveyor belt cutting device to solve the technical problem that the device itself will shift position during the actual cutting process, which will affect the overall cutting accuracy, and the cutting blade is very easy to get stuck during the flat cutting process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for a flame-retardant conveyor belt with a fabric core in a coal mine, comprising a cutting table and a pressure plate. The pressure plate is slidably positioned on top of the cutting table. An electric sliding groove is provided on the top of the cutting table, wherein an electric slider is slidably positioned within the electric sliding groove. A cutting component is provided on top of the electric slider. An irregularly shaped sliding groove is provided within the electric sliding groove, wherein the irregularly shaped sliding groove itself is corrugated, and the cutting component is located on top of the electric slider and is reciprocatingly slidably positioned.

[0007] By adopting the above technical solution, the toothed block will drive the pressure plate to slide downward under the action of gear meshing, thereby limiting the conveyor belt to be cut. During this process, it is ensured that the conveyor belt itself will not shift position during the sliding cutting process of the cutting component, which further improves the overall cutting accuracy. With the cooperation of the irregular slid and the guide column, the cutting component can slide back and forth in the vertical direction, effectively preventing the cutting component from getting stuck during the flat cutting process.

[0008] The present invention is further configured such that a toothed block is provided on one side of the electric slider, wherein a driving gear is meshed on one side of the toothed block, and the driving gear meshes with the driven gear. A threaded rod is provided on the top of the driven gear, wherein the contact surface between the pressure plate and the threaded rod is threaded.

[0009] Preferably, when the electric slider slides to one side under the action of the electric sliding groove, the toothed block on one side will drive the driving gear to rotate, and through meshing with the driven gear, it will drive the threaded rod at the top to rotate. Since the contact surface between the pressure plate and the threaded rod is threaded, the pressure plate itself will adjust its position during the rotation of the threaded rod.

[0010] The present invention is further provided that the top of the cutting table is provided with a guide rod that cooperates with the threaded rod.

[0011] Preferably, the guide rod prevents the pressure plate from rotating along with the threaded rod during rotation, thus ensuring the stability of the pressure plate at the top of the cutting table and further improving the overall practicality of the device.

[0012] The present invention is further configured such that the electric slider is internally elastically provided with a guide post, wherein the bottom end of the guide post is arc-shaped.

[0013] Preferably, during the sliding process of the electric slider, the guide post reciprocates vertically through the action of the irregular groove, and the arc-shaped design at the bottom prevents the guide post from getting stuck during the sliding process.

[0014] The present invention is further configured such that the driving gear and the driven gear mesh with each other, and the outer diameter of the driving gear is larger than the outer diameter of its driven gear.

[0015] Preferably, during the rotation of the drive gear, it drives the driven gear on one side to rotate, thereby driving the threaded rod at the top of the driven gear to rotate. Since the outer diameter of the drive gear is larger than the outer diameter of its driven gear, when the drive gear rotates several times, the driven gear will drive the threaded rod to rotate several times more times, further ensuring the stability of the pressure plate at the top of the cutting table.

[0016] The present invention is further configured such that the bottom of the pressure plate is provided with a cutting groove for the cutting assembly to slide, and the contact surface between the guide rod and the pressure plate is smooth.

[0017] Preferably, the cutting groove is designed to ensure that the cutting component itself will slide to one side and cut while the pressure plate limits the conveyor belt itself.

[0018] The present invention is further provided that the bottom of the pressure plate is symmetrically provided with protective sleeves on both sides of the cutting groove, wherein the protective sleeves themselves are detachable.

[0019] Preferably, the protective sleeve is provided to prevent the pressure plate from causing wear on the outer wall of the conveyor belt during the limiting and squeezing process.

[0020] The present invention is further configured such that an elastic component is provided on the outer wall of the guide post, wherein the elastic component itself is located inside the electric slider.

[0021] Preferably, under the action of the elastic component, the guide post itself will reciprocate during the sliding process of the electric slider.

[0022] The present invention is further configured such that the bottom end of the cutting table is provided with an array of support legs, and the top of the table is provided with a smooth surface.

[0023] Preferably, the support legs effectively prevent dirt and impurities from the ground from contaminating the conveyor belt on the cutting table.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model has a toothed block on one side of the electric slider. When the cutting assembly cuts the conveyor belt, the toothed block will drive the pressure plate to slide downward under the action of gear meshing, thereby limiting the conveyor belt to be cut. In this process, it is ensured that the conveyor belt itself will not shift position during the sliding cutting process of the cutting assembly, which further improves the overall cutting accuracy.

[0026] 2. This utility model features an irregularly shaped sliding groove within the electric sliding groove. This irregularly shaped sliding groove is corrugated. As the electric slider moves the cutting component, the irregularly shaped sliding groove, in conjunction with the guide post, allows the cutting component to slide back and forth in the vertical direction. This effectively prevents the cutting component from jamming during the flat cutting process, thereby improving the overall cutting efficiency. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] First embodiment:

[0037] Please see Figures 1-5 The illustrated coal mine fabric core flame-retardant conveyor belt cutting equipment includes a cutting table 1, a pressure plate 2, a cutting component 5, a limiting mechanism, and a sliding mechanism. The pressure plate 2 is located on top of the cutting table 1 and is slidably configured. The operator passes the fabric core flame-retardant conveyor belt to be cut between the cutting table 1 and the pressure plate 2. An electric sliding groove 6 is provided on the top of the cutting table 1, in which an electric slider 10 is slidably configured. The cutting component 5 is provided on top of the electric slider 10. Under the action of the electric sliding groove 6, the electric slider 10 is driven to slide to one side. During this process, a toothed block 12 is provided on one side of the electric slider 10, and a drive gear 9 is meshed on one side of the toothed block 12. The drive gear 9 meshes with a driven gear 8. A threaded rod 4 is provided on top of the driven gear 8. The contact surface between the pressure plate 2 and the threaded rod 4 is threaded.

[0038] When the electric slider 10 slides to one side under the action of the electric sliding groove 6, the toothed block 12 on one side will drive the drive gear 9 to rotate. Through meshing with the driven gear 8, it will drive the threaded rod 4 at the top to rotate. Since the contact surface between the pressure plate 2 and the threaded rod 4 is threaded, the pressure plate 2 will adjust its position to limit the flame-retardant conveyor belt of the fabric core to be cut during the rotation of the threaded rod 4. At the same time, the electric sliding groove 6 is provided with a special-shaped sliding groove 7, which is corrugated. The cutting component 5 is located on the top of the electric slider 10 and is reciprocating. Through the cooperation of the special-shaped sliding groove 7 and the guide post 11, the cutting component 5 reciprocates in the vertical direction, effectively preventing the cutting component 5 from getting stuck during the flat cutting process, thereby improving the overall cutting efficiency.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The top of the cutting table 1 is provided with a guide rod 3 that cooperates with the threaded rod 4. The guide rod 3 prevents the pressure plate 2 from rotating along with the threaded rod 4 during rotation. The guide rod 3, together with the pressure plate 2, ensures the stability of the pressure plate 2 at the top of the cutting table 1, further improving the overall practicality of the device.

[0040] Second embodiment:

[0041] Please see Figure 3 The coal mine fabric core flame-retardant conveyor belt cutting device shown has an overall structure similar to that of Embodiment 1. The driving gear 9 and the driven gear 8 mesh with each other, and the outer diameter of the driving gear 9 is larger than that of the driven gear 8. During the rotation of the driving gear 9, it will drive the driven gear 8 on one side to rotate, thereby driving the threaded rod 4 at the top of the driven gear 8 to rotate. Since the outer diameter of the driving gear 9 is larger than that of the driven gear 8, when the driving gear 9 rotates several times, the driven gear 8 will drive the threaded rod 4 to rotate several times, further ensuring the stability of the pressure plate 2 at the top of the cutting table 1.

[0042] In practical operation, this invention involves passing the flame-retardant conveyor belt of the fabric core to be cut between the cutting table 1 and the pressure plate 2. Through the cooperation of the electric sliding groove 6 and the electric slider 10, the cutting assembly 5 slides to one side of the conveyor belt. During this process, the toothed block 12 of the electric slider 10 drives the drive gear 9 to rotate. Meshing with the driven gear 8, the pressure plate 2 slides downwards. This ensures that the pressure plate 2 limits the position of the flame-retardant conveyor belt of the fabric core during the sliding cutting process of the cutting assembly 5, preventing the conveyor belt from shifting position. Furthermore, a shaped sliding groove 7 is provided within the electric sliding groove 6. Through the cooperation of the shaped sliding groove 7 and the guide post 11, the cutting assembly 5 reciprocates in the vertical direction, effectively preventing jamming during horizontal cutting and thus improving overall cutting efficiency.

[0043] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
