Description

Technical Field

[0001] The present invention relates to the technical field of belt cutting machines, and in particular to a belt cutting machine. Background Art

[0002] Steel cord conveyor belt is a high-strength, high-load capacity conveyor belt, widely used in material transportation in mining, ports, power, chemical and other industries. Steel cord conveyor belt usually includes steel cord core and covering layer. Steel cord core is the skeleton of conveyor belt, which is composed of high-strength steel wire rope. The diameter, strength and number of steel wire rope determine the carrying capacity and tensile strength of conveyor belt. Steel cord core is usually located in the center of conveyor belt, which plays the role of supporting and pulling the whole belt body. The covering layer is usually made of wear-resistant rubber, covering the upper and lower sides of steel cord core. To protect the steel cord core from direct wear of materials.

[0003] During long-term use, the conveyor belt will wear and age due to friction of the carried materials and environmental factors (such as temperature, humidity, and erosion by chemicals). At this time, when the conveyor belt needs to be maintained or replaced locally, the conveyor belt needs to be cut and reconnected.

[0004] In the prior art, conveyor belts are usually cut by belt cutting machines. The belt cutting machine usually includes a cutting part, and when the cutting part cuts the conveyor belt, it cuts the upper and lower rubber layers and the steel wire rope core at the same time. However, the material and hardness of the upper and lower rubber layers and the steel wire rope core are quite different. It is often difficult to ensure that the cut surface of the steel wire rope core is flat when cutting the upper and lower rubber layers and the steel wire rope core at the same time, which will cause the end face of the steel wire rope core after cutting to be uneven, affecting the subsequent use and joint quality. Summary of the invention

[0005] The present invention provides a belt cutting machine to solve the problem in the prior art that it is often difficult to ensure that the cut surface of the steel wire rope core is flat when cutting the upper and lower rubber layers and the steel wire rope core at the same time, and the end surface of the steel wire rope core after cutting is uneven, which affects the subsequent use and joint quality.

[0006] The present invention provides a belt cutting machine for cutting a conveyor belt, wherein the conveyor belt comprises a steel cord core, a first rubber layer and a second rubber layer, wherein the first rubber layer and the second rubber layer are respectively coated on two oppositely arranged surfaces of the steel cord core. The belt cutting machine comprises: a first rubber layer stripping portion, wherein the first rubber layer stripping portion is used for stripping the steel cord core and the first rubber layer of the conveyor belt so as to separate the first rubber layer from the steel cord core; and a cutting portion, which is arranged downstream of the first rubber layer stripping portion and is used for cutting the steel cord core and the second rubber layer.

[0007] Further, the cutting part comprises: a second rubber layer cutting part for cutting the second rubber layer; a steel wire core cutting part for cutting the steel wire core, and the second rubber layer cutting part is located upstream of the steel wire core cutting part.

[0008] Furthermore, the belt cutting machine further comprises: a frame, and the first rubber layer stripping part, the second rubber layer cutting part and the steel wire rope core cutting part are all arranged on the frame.

[0009] Furthermore, the first rubber layer stripping part includes: a mounting frame, which is arranged on the frame; a stripping blade, which extends along the length direction of the conveyor belt and is parallel to the conveyor belt, and the stripping blade is arranged on the mounting frame. The stripping blade is used to strip the first rubber layer, and a first penetration channel for the stripped first rubber layer to pass through is formed between the stripping blade and the mounting frame.

[0010] Furthermore, the first rubber layer stripping part also includes: a first rubber layer cutting part, which is arranged on the stripping blade and located in the first penetration channel, and the first rubber layer cutting part extends along the length direction of the stripping blade, and is used to cut the stripped first rubber layer.

[0011] Furthermore, the side of the second rubber layer cutting portion facing the conveyor belt includes a contact plane, which is used to contact the second rubber layer. The first blade of the second rubber layer cutting portion is located on the side of the contact plane away from the conveyor belt. Along the direction from the first rubber layer stripping portion to the second rubber layer cutting portion, the distance between the first blade and the contact plane gradually increases.

[0012] Furthermore, the wire rope core cutting part includes: a knife seat, which is arranged on the frame, and the knife seat extends in the direction from the first rubber layer stripping part to the second rubber layer cutting part; a wire rope core cutting knife, which is rotatably arranged on the frame and arranged opposite to the knife seat, and a second insertion channel for the wire rope core and the second rubber layer to be inserted is formed between the wire rope core cutting knife and the knife seat; a driving part, which is arranged on the frame and is drivingly connected to the wire rope core cutting knife to rotate the wire rope core cutting knife.

[0013] Furthermore, a cutting groove is provided on one side of the knife seat facing the wire rope core cutting knife, and the cross-sectional area of ​​the cutting groove gradually decreases along the direction from the wire rope core cutting knife to the knife seat, and the contour of the second blade of the wire rope core cutting knife is adapted to the contour of the cutting groove.

[0014] Furthermore, the knife seat and the second rubber layer cutting portion are located on the same side of the conveyor belt, and the wire rope core cutting knife and the first rubber layer stripping portion are located on the same side of the conveyor belt.

[0015] Furthermore, the driving part comprises: a driving member, which is arranged on the frame; a speed reduction mechanism, which is arranged on the frame, and the driving part is connected to the wire rope core cutting knife through the speed reduction mechanism.

[0016] By applying the technical solution of the present invention, the first rubber layer and the steel wire core are separated, and then the steel wire core and the second rubber layer are cut, the flatness of the cut surface of the steel wire core can be improved, and the unevenness of the end surface of the steel wire core after cutting can be reduced. Specifically, when cutting the conveyor belt, the first rubber layer is firstly peeled off from the steel wire core by the first rubber layer peeling part, so as to remove the rubber layer that may affect the flatness of the cut surface of the steel wire core before cutting the steel wire core. The rubber material is soft and elastic. If the first rubber layer, the steel wire core and the second rubber layer are cut at the same time, the first rubber layer and the second rubber layer will be deformed during the cutting process, affecting the flatness of the cut surface of the steel wire core. In this solution, after peeling off the first rubber layer, the cutting part cuts the remaining part of the conveyor belt. At this time, when the cutting part cuts the steel wire core and the second rubber layer, it will not be disturbed by the first rubber layer, thereby improving the flatness of the cut surface of the steel wire core.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0035] like Figure 1 As shown, an embodiment of the present invention provides a belt cutting machine for cutting a conveyor belt, wherein the conveyor belt comprises a steel cord core, a first rubber layer and a second rubber layer, wherein the first rubber layer and the second rubber layer are respectively coated on two oppositely disposed surfaces of the steel cord core. The belt cutting machine comprises a first rubber layer stripping section 10 and a cutting section. The first rubber layer stripping section 10 is used to strip the steel cord core and the first rubber layer of the conveyor belt so as to separate the first rubber layer from the steel cord core; the cutting section is disposed downstream of the first rubber layer stripping section 10, and the cutting section is used to cut the steel cord core and the second rubber layer.

[0036] By applying the technical solution of the present invention, the first rubber layer and the steel wire core are separated, and then the steel wire core and the second rubber layer are cut, the flatness of the cut surface of the steel wire core can be improved, and the unevenness of the end surface of the steel wire core after cutting can be reduced. Specifically, when cutting the conveyor belt, the first rubber layer is firstly peeled off from the steel wire core by the first rubber layer peeling unit 10, so as to remove the rubber layer that may affect the flatness of the cut surface of the steel wire core before cutting the steel wire core. The rubber material is soft and elastic. If the first rubber layer, the steel wire core and the second rubber layer are cut at the same time, the first rubber layer and the second rubber layer will both be deformed during the cutting process, affecting the flatness of the cut surface of the steel wire core. In this solution, after peeling off the first rubber layer, the cutting unit cuts the remaining part of the conveyor belt. At this time, the cutting unit will not be disturbed by the first rubber layer when cutting the steel wire core and the second rubber layer, thereby improving the flatness of the cut surface of the steel wire core.

[0037] When cutting conveyor belts, traditional belt cutting machines usually cut the first rubber layer, the steel cord core and the second rubber layer at the same time. The rubber layer is easily deformed and squeezed during the cutting process, resulting in the phenomenon of belt jam. In this solution, by pre-peeling the first rubber layer, the occurrence of belt jam when cutting the steel cord core can be effectively reduced, ensuring the continuity and smoothness of the steel cord core cutting process.

[0038] like Figure 1 As shown, further, the cutting part includes a second rubber layer cutting part 20 and a steel wire rope core cutting part 30, the second rubber layer cutting part 20 is used to cut the second rubber layer; the steel wire rope core cutting part 30 is used to cut the steel wire rope core, and the second rubber layer cutting part 20 is located upstream of the steel wire rope core cutting part 30. The above arrangement allows, after peeling off the first rubber layer, to first cut the second rubber layer of relatively soft material, and then cut the steel wire rope core of relatively high hardness and relatively complex structure, which can further improve the flatness of the cutting surface of the steel wire rope core and improve the cutting accuracy. In addition, cutting the second rubber layer first and then cutting the steel wire rope core can reduce the time that the tool is in direct contact with the steel wire rope core, thereby extending the service life of the cutting tool and reducing maintenance costs.

[0039] In the embodiment of this scheme, the mechanical strength of the second rubber layer cutting part 20 is less than the mechanical strength of the steel wire rope core cutting part 30. In this scheme, the second rubber layer cutting part 20 first cuts the second rubber layer, and after cutting, the first rubber layer and the second rubber layer of the conveyor belt have been completely cut, and only the steel wire rope core is left uncut. At this time, the steel wire rope core cutting part 30 can directly act on the steel wire rope core, and the steel wire rope core cutting part 30 can process the steel wire rope core more intensively when cutting, avoiding most of the interference of the second rubber layer on the steel wire rope core cutting process, reducing the resistance when cutting the steel wire rope core, improving the cutting quality of the conveyor belt, improving the smoothness and safety of the cutting process, and improving the overall cutting speed and efficiency.

[0040] like Figure 1 As shown, further, the belt cutting machine also includes a frame 40, and the first rubber layer stripping part 10, the second rubber layer cutting part 20 and the wire rope core cutting part 30 are all arranged on the frame 40. The above arrangement allows the conveyor belt to be cut in a continuous manner from stripping the first rubber layer to cutting the second rubber layer, and then to cutting the wire rope core. The frame 40, as the foundation of the entire belt cutting machine, provides stable support for all components, ensuring that the relative positions of the various components will not change during the cutting process, thereby enhancing the stability and reliability of the overall structure. In addition, this integrated structural design can improve the structural compactness of the device.

[0041] like Figure 1 and Figure 5 As shown, further, the first rubber layer stripping part 10 includes a mounting frame 11 and a stripping blade 12. The mounting frame 11 is arranged on the frame 40; the stripping blade 12 is arranged on the mounting frame 11, and the stripping blade 12 extends along the length direction of the conveyor belt and is parallel to the conveyor belt. The stripping blade 12 is used to strip the first rubber layer, and a first passing channel for the first rubber layer to be stripped is formed between the stripping blade 12 and the mounting frame 11. The stripping blade 12 arranged on the mounting frame 11 is used to strip the first rubber layer of the conveyor belt from the steel wire rope core to facilitate the subsequent cutting step. Specifically, when stripping the first rubber layer, the stripping blade 12 is aligned with the connection interface between the steel wire rope core and the first rubber layer, and the conveyor belt and the stripping blade 12 move relative to each other, so that the stripping operation of the first rubber layer can be realized.

[0042] Furthermore, the first rubber layer stripping section 10 also includes a first rubber layer cutting section 101, which is arranged on the stripping blade 12 and is located in the first penetration channel. The first rubber layer cutting section 101 extends along the length direction of the stripping blade 12, and the first rubber layer cutting section 101 is used to cut the stripped first rubber layer. The above arrangement enables the first rubber layer cutting section 101 to cut the first rubber layer along the stripping direction after the stripping blade 12 strips the first rubber layer from the steel wire rope core, thereby ensuring the flatness of the cut surface of the first rubber layer.

[0043] Specifically, the blade of the first rubber layer cutting part 101 is away from the stripping blade 12, and the distance between the blade of the first rubber layer cutting part 101 and the stripping blade 12 gradually increases along the direction from the first rubber layer stripping part 10 to the second rubber layer cutting part 20, and the end of the first rubber layer cutting part 101 away from the second rubber layer cutting part 20 is flush with the end of the stripping blade 12 away from the second rubber layer cutting part 20. The above arrangement enables the first rubber layer cutting part 101 and the stripping blade 12 to act on the first rubber layer almost simultaneously, and when the first rubber layer cutting part 101 cuts the first rubber layer, the cutting depth of the first rubber layer by the first rubber layer cutting part 101 gradually deepens, which reduces the occurrence of the phenomenon that the first rubber layer cannot be cut smoothly due to warping and other reasons after being stripped, and improves the flatness of the cut surface of the first rubber layer.

[0044] In the embodiment of the present solution, the stripping blade 12 is symmetrically arranged relative to the first rubber layer cutting portion 101 along the extension direction of the first rubber layer cutting portion 101. Such arrangement can ensure that the first rubber layer is cut into two parts with the same width.

[0045] like Figure 4 As shown, further, the side of the second rubber layer cutting part 20 facing the conveyor belt includes a contact plane 201, and the contact plane 201 is used to contact the second rubber layer. The first blade 202 of the second rubber layer cutting part 20 is located on the side of the contact plane 201 away from the conveyor belt, and the distance between the first blade 202 and the contact plane 201 gradually increases along the direction from the first rubber layer stripping part 10 to the second rubber layer cutting part 20. The above arrangement enables the contact plane 201 to provide support for the movement of the conveyor belt, which helps the first blade 202 to evenly apply force to the second rubber layer during the process of cutting the second rubber layer, reduces the cutting deviation or uneven cutting surface caused by the instability of the contact surface between the second rubber layer and the second rubber layer cutting part 20, and improves the stability of the second rubber layer cutting part 20 when cutting the second rubber layer.

[0046] In this solution, the distance between the first blade 202 and the abutment plane 201 gradually increases along the direction from the first rubber layer stripping portion 10 to the second rubber layer cutting portion 20. Specifically, the tip of the first blade 202 will first contact the second rubber layer. As the conveyor belt advances relative to the belt cutter, the first blade 202 gradually cuts the second rubber layer, so that the second rubber layer is cut into two left and right parts. Such a design helps to form a progressive cutting path when cutting the second rubber layer, so that the first blade 202 enters the second rubber layer with a smaller cutting depth at the beginning of cutting. As the conveyor belt advances relative to the belt cutter, the cutting depth gradually increases, which can reduce the resistance in the initial stage of cutting, improve cutting efficiency, and ensure that the second rubber layer is cut evenly and smoothly.

[0047] like Figure 2 As shown, further, the steel wire rope core cutting part 30 includes a knife seat 31, a steel wire rope core cutting knife 32 and a driving part 33. The knife seat 31 is arranged on the frame 40, and the knife seat 31 extends in the direction from the first rubber layer stripping part 10 to the second rubber layer cutting part 20; the steel wire rope core cutting knife 32 is rotatably arranged on the frame 40, and is arranged opposite to the knife seat 31 in the height direction, and a second insertion channel for the steel wire rope core and the second rubber layer to be inserted is formed between the steel wire rope core cutting knife 32 and the knife seat 31; the driving part 33 is arranged on the frame 40, and is connected to the steel wire rope core cutting knife 32 by driving. Specifically, after the steel wire rope core and the second rubber layer pass through the second rubber layer cutting part 20, the steel wire rope core and the second rubber layer pass through the second insertion channel, and under the drive of the driving part 33, the steel wire rope core cutting knife 32 rotates at a high speed, and cuts the steel wire rope core with the cooperation of the knife seat 31. With such an arrangement, the steel wire core cutting knife 32 only needs to cut the steel wire core, thereby improving the flatness of the cut surface of the steel wire core.

[0048] like Figure 3 As shown, further, a cutting groove 3101 is provided on the side of the knife seat 31 facing the wire rope core cutting knife 32, and the cross-sectional area of ​​the cutting groove 3101 gradually decreases along the direction from the wire rope core cutting knife 32 to the knife seat 31, and the profile of the second blade 3201 of the wire rope core cutting knife 32 is adapted to the profile of the cutting groove 3101. With such a configuration, the cutting angle of the wire rope core cutting knife 32 during the cutting process can be controlled to ensure that the wire rope core cutting knife 32 will not have an excessive angle deviation; the wire rope core and the second rubber layer have a certain deformation capacity, and under the action of the wire rope core cutting knife 32, the wire rope core and the second rubber layer are deformed, and the side of the second rubber layer away from the wire rope core is in contact with the cutting groove 3101, which reduces the deviation of the second rubber layer and the wire rope core, and improves the stability of the second rubber layer and the wire rope core during the cutting process.

[0049] In the embodiment of the present scheme, the cutting groove 3101 and the second blade 3201 both adopt a V-shaped profile, and the two are adapted to each other. Cutting by the V-shaped blade can reduce the possibility of divergence of the wire rope core after cutting, thereby ensuring the stability of the wire rope core cutting knife 32 during the cutting process, so that the wire rope core cutting knife 32 can accurately cut the wire rope core along a preset path, reducing the deviation and swing of the wire rope core cutting knife 32 during cutting.

[0050] In the embodiment of this solution, the blade of the first rubber layer cutting part 101, the first blade 202 of the second rubber layer cutting part 20 and the second blade 3201 of the steel cord cutting knife 32 are in the same vertical plane, and the conveyor belt is symmetrical with respect to the vertical plane. Such an arrangement can further improve the flatness of the cutting surface of the conveyor belt.

[0051] Furthermore, the knife seat 31 and the second rubber layer cutting part 20 are located on the same side of the conveyor belt, and the steel cord core cutting knife 32 and the first rubber layer stripping part 10 are located on the same side of the conveyor belt. Specifically, the knife seat 31 and the second rubber layer cutting part 20 are located on the lower side of the conveyor belt, and the steel cord core cutting knife 32 and the first rubber layer stripping part 10 are located on the upper side of the conveyor belt. Such a layout design allows a smooth operation process from stripping and cutting the first rubber layer, to cutting the second rubber layer, and finally cutting the steel cord core along the advancement of the conveyor belt without affecting each other.

[0052] like Figure 1 As shown, specifically, the driving part 33 includes a driving member 331 and a reduction mechanism 332 . The driving member 331 and the reduction mechanism 332 are both arranged on the frame 40 . The driving member 331 is drivingly connected to the wire rope core cutting knife 32 through the reduction mechanism 332 .

[0053] In the embodiment of the present scheme, the frame 40 has a head end and a tail end which are arranged oppositely along the length direction, and the head end is located in front of the tail end. The frame 40 includes a chassis 41, a running wheel 42, a push rod 43, a support column 44 and a support frame 45 which are arranged in sequence from bottom to top. Among them, there are four running wheels 42, and the four running wheels 42 are installed at the four corners of the bottom of the chassis 41. The push rod 43 is arranged at the tail end of the length direction of the chassis 41. The support column 44 is arranged at the top of the chassis 41 and is close to the push rod 43. The support frame 45 extends along the length direction of the chassis 41, one end of the support frame 45 in the length direction is arranged at the top of the support column 44, and the other end of the support frame 45 in the length direction is located above the chassis 41 and is spaced apart from the chassis 41.

[0054] The front and rear ends of the chassis 41 are respectively provided with a connecting plate, and the width of the connecting plate is greater than the width at the middle position of the chassis 41. Such an arrangement expands the width of the bottom end of the entire belt cutter and improves the stability of the belt cutter.

[0055] Further, the knife seat 31 is arranged on the top of the chassis 41, and the knife seat 31 is located at one end of the support column 44 away from the push rod 43. The wire rope core cutting knife 32 is rotatably arranged on the support frame 45, and the wire rope core cutting knife 32 and the knife seat 31 are arranged opposite to each other in the height direction.

[0056] Specifically, the support frame 45 includes a support plate 451 and a baffle plate 452. Two support plates 451 are arranged opposite to each other along the width direction of the chassis 41. One end of the two support plates 451 is respectively arranged on the top of the support column 44, and the baffle plate 452 is arranged at one end of the two support plates 451 away from the support column 44. An enclosed space is formed between the baffle plate 452 and the two support plates 451. The steel wire rope core cutting knife 32 is located in the enclosed space. The steel wire rope core cutting knife 32 is rotatably arranged on the two support plates 451.

[0057] Furthermore, the belt cutting machine further includes a protective cover 50, the bottom of which is an open structure, and the protective cover 50 is arranged on the top of the two support plates 451, and is used to enclose the open structure at the top of the enclosure space. The protective cover 50 can prevent the wire rope core cutting knife 32 from deviating from the device and flying out during operation to cause a safety accident, and can also prevent fine slag particles from scattering everywhere.

[0058] like Figure 3 As shown, in the embodiment of the present scheme, the belt cutting machine further includes a cutting knife fixed shaft 322, a flat key 321 and a deep groove ball bearing 323. Among them, the wire rope core cutting knife 32 has a connecting hole, the connecting hole is coaxial with the wire rope core cutting knife 32, the cutting knife fixed shaft 322 is penetrated in the connecting hole, and the cutting knife fixed shaft 322 is coaxial with the cutting knife fixed shaft 322 and connected through the flat key 321. The outer ring of the deep groove ball bearing 323 is fixedly installed with the support plate 451 by interference fit, and one end of the cutting knife fixed shaft 322 is penetrated inside the inner ring of the deep groove ball bearing 323 and fixedly connected with the inner ring of the deep groove ball bearing 323. The output shaft of the speed reduction mechanism 332 is fixedly connected with the cutting knife fixed shaft 322.

[0059] Further, the second rubber layer cutting portion 20 is disposed on the bottom plate 41 , and the second rubber layer cutting portion is located at an end of the knife seat 31 away from the support column 44 .

[0060] Furthermore, the bottom end of the baffle plate 452 protrudes downward from the bottom end of the support plate 451 , and the mounting frame 11 is disposed at the bottom end of the baffle plate 452 .
