Description

Technical Field

[0001] The invention relates to the field of conveyor belts, and in particular to a combined module conveyor belt that is easy to assemble and disassemble. Background Art

[0002] At present, modular conveyor belts are widely used in various fields due to their advantages of small offset and easy assembly. Existing modular conveyor belts usually use pins to assemble adjacent combination modules. One end of the existing pin is provided with a top surface with a diameter larger than the diameter of the pin shaft, and the other end of the pin has a thread. After the pin is inserted into the pin hole of the combination module, the threaded end of the pin is screwed with a nut, and the position of the pin can be restricted by the top surface of one end of the pin and the nut at the other end, thereby realizing the connection between adjacent combination modules.

[0003] However, when the combined module of the conveyor belt needs to be disassembled and replaced, multiple pins need to be disassembled, and the disassembly process is complicated, resulting in a long disassembly and assembly time and low efficiency. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a combined module conveyor belt that is easy to assemble and disassemble, thereby improving the efficiency of assembling and disassembling the combined modules.

[0005] The purpose of the present invention is achieved by the following technical solutions:

[0006] A combined modular conveyor belt that is easy to assemble and disassemble, comprising:

[0007] The through-shaft comprises a shaft and a pin, wherein the two ends of the shaft are provided with pins, the outer surface of the pin protrudes outward to form a fixing rib, and a through hole 1 is passed through the pin, and the through hole 1 and the fixing rib are arranged at the same level as the pin;

[0008] Combination module, both ends of the combination module are provided with staggered connection blocks, each connection block is provided with a pin hole; the shaft rod passes through the pin holes of the connection blocks of the adjacent combination modules, pins are respectively installed on both ends of the shaft rod, and the fixing ribs of the pins are pushed into the pin holes, so that the fixing ribs abut between the two staggered spliced ​​connection blocks at the outermost ends of the adjacent combination modules, so as to realize the mutual splicing of adjacent combination modules; several adjacent combination modules are spliced ​​to form a conveyor belt.

[0009] Furthermore, two symmetrical fixing ribs are arranged on the outer surface of the pin, and a through hole 1 is formed between the two fixing ribs.

[0010] Furthermore, the protruding height of the fixing rib gradually decreases from the middle of the fixing rib to both ends of the fixing rib.

[0011] Furthermore, a through hole 2 is passed through the shaft of the pin, the through hole 2 has the same opening direction as the through hole 1, and the through hole 2 is connected to the through hole 1.

[0012] Furthermore, the width of the through hole one is greater than the width of the through hole two, and the length of the through hole one is greater than the length of the fixing rib.

[0013] Furthermore, the straight line where the inner end of the fixing rib is located coincides with the straight line where the through hole 1 and the through hole 2 are connected.

[0014] Furthermore, the widths between adjacent connection blocks in the same combined module are the same, and the inner side of the outermost connection block in the combined module is recessed inwardly, and the recessed area is larger than the pin hole area.

[0015] Furthermore, the recessed depth of the outermost connecting block in the combined module is equal to the width of the fixing rib.

[0016] Furthermore, the connection block at the outermost end of the combined module extends outward horizontally, so that its width is greater than the width of the connection block in the middle of the combined module.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) The outer surface of the pin protrudes outward to form a fixing rib, and the fixing rib is pushed between two adjacent connecting blocks of different combination modules, so that the through shaft is restricted in the pin hole and cannot move, thereby playing the role of fixing the combination module;

[0019] (2) A through hole is passed through the pin at the fixing rib. The presence of the through hole can increase the elasticity of the pin at the fixing rib, making it easier to push the protruding fixing rib into or out of the pin hole of the connecting block, thereby improving the efficiency of disassembly of the through-shaft.

[0027] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0028] A combined module conveyor belt which is easy to assemble and disassemble comprises a through shaft 3 and a plurality of combined modules 1 connected by the through shaft 3.

[0029] The through shaft 3 in this embodiment is configured as a long cylindrical structure made of plastic material. The through shaft 3 made of plastic material is configured as a solid shaft body, and its length can be adjusted according to the actual width of the conveyor belt.

[0030] like Figures 1 to 6 As shown, the through-shaft 3 includes a shaft 301 and a pin 302, with protrusions at both ends of the shaft 301, and correspondingly, a groove corresponding to the protrusion is provided at one end of the pin 302, and the protrusion of the shaft 301 can be inserted into the groove of the pin 302 by pushing the pin 302 toward the end of the shaft 301 by external force, so that the shaft 301 and the pin 302 are connected to form a complete through-shaft 3. After both ends of the shaft 301 are buckled with the pin 302, the length of the through-shaft 3 is the same as the length of the combined module 1.

[0031] The outer surface of the pin 302 protrudes outward to form a fixing rib 4, which is used to limit the pin 302 on two adjacent connecting blocks 2, so that the through shaft 3 cannot be displaced after the conveyor belt is assembled, thereby maintaining the stability of the conveyor belt. The fixing rib 4 can be set as an annular structure surrounding the outside of the shaft of the pin 302, or multiple fixing ribs 4 can be set to be fixed outside the shaft on the same horizontal plane of the pin 302. In this embodiment, two fixing ribs 4 are set, and the two fixing ribs 4 are distributed on the outer surface of the shaft of the pin 302. The diameter of the shaft rod 301 is smaller than the diameter of the pin hole on the connecting block 2, while the diameter of the pin 302 at the fixing rib 4 is larger than the diameter of the pin hole on the connecting block 2, so that the shaft rod 301 can freely pass through the pin hole, and the fixing rib 4 cannot pass through the pin hole without the action of external force, thereby playing a limiting role.

[0032] In this embodiment, two fixing ribs 4 are symmetrically arranged on the pin 302, and a through hole 5 is formed between the two fixing ribs 4. The through hole 5 and the fixing rib 4 are arranged at the same horizontal height of the pin 302. The existence of the through hole 5 can make the plastic pin 302 have a certain elasticity. The external force squeezing the fixing rib 4 can make the fixing rib 4 squeezed toward the axial direction of the pin 302, so that the pin 302 with the fixing rib 4 can pass through the pin hole of the connecting block 2; when the pin 302 is not squeezed by external force, the elastic deformation of the pin 302 is restored so that the fixing rib 4 protrudes again, making it impossible for the pin 302 with the fixing rib 4 to pass through the next pin hole, thereby limiting the fixing rib 4 of the pin 302 between two adjacent connecting blocks 2, thereby playing the role of connecting the combined module 1.

[0033] The connection blocks 2 are arranged at both ends of the combination module 1, and the connection blocks 2 at both ends of the same combination module 1 are staggered. When adjacent combination modules 1 are arranged longitudinally, the connection blocks 2 of adjacent combination modules 1 are staggered and spliced; the shaft rod 301 is inserted into the pin holes of the mutually spliced ​​connection blocks 2, and then the pin 302 is inserted into the pin hole. The fixing rib 4 of the pin 302 is abutted between the two staggered spliced ​​connection blocks 2 at the outermost ends of the adjacent combination modules 1 by external force, and the groove of the pin 302 is inserted into the protrusion of the shaft rod 301, so that the adjacent combination modules 1 can be spliced ​​together.

[0034] In order to increase the sinking depth of the fixed rib 4 and facilitate the passage of the fixed rib 4 through the pin hole, the length of the through hole 15 is greater than the length of the fixed rib 4, and a through hole 26 is penetrated on the shaft body of the through shaft 3. The through hole 26 has the same opening direction as the through hole 15, and the through hole 26 is connected to the through hole 15. The existence of the through hole 26 increases the deformable range of the shaft body of the through shaft 3, that is, in addition to the elastic deformation of the through hole 15 on the through shaft 3, the through hole 26 connected to the through hole 15 can also undergo elastic deformation, providing a larger elastic space for the fixed rib 4, so that the extrusion sinking depth of the fixed rib 4 can be increased, thereby improving the ease with which the fixed rib 4 passes through the pin hole; in addition, the protruding height of the fixed rib 4 gradually decreases from the middle of the fixed rib 4 to both sides, and the inclined surfaces on both sides of the fixed rib 4 enable the pin 302 to pass through the pin hole more effortlessly and smoothly under the push of external force, thereby avoiding damage to the pin 302 caused by excessive external force.

[0035] Since the opening range of through hole 1 5 and through hole 2 6 is relatively wide, when the fixing rib 4 is squeezed and sunken into through hole 1 5, the most vulnerable positions are the two ends of the fixing rib 4 with the smallest protruding height. In order to avoid the pin 302 near through hole 1 5 from breaking, the width of through hole 1 5 is set to be larger than the width of through hole 2 6, and the width of through hole 2 6 is small, so that the thickness of the pin 302 at through hole 2 6 is larger than the thickness of the pin 302 at through hole 1 5; and the fixing rib 4 is set at the position where the pin 302 is close to through hole 2 6, so that the straight line where the inner end of the fixing rib 4 is located (such as Figure 2 The horizontal line where point a is located coincides with the straight line where through hole 1 5 and through hole 2 6 are connected; when the fixed rib 4 sinks, the inner wall of the pin 302 at through hole 2 6 can provide a certain supporting force and buffering force for the inner wall of the pin 302 at through hole 1 5, so as to bear part of the pressure at the sunken part of the fixed rib 4, thereby increasing the pressure-bearing capacity of the pin 302 at the inner end of the fixed rib 4, avoiding the breakage of the pin 302 at through hole 1 5 and increasing the service life of the pin 302.

[0036] Since the fixing rib 4 is fixed with a certain width, when the fixing rib 4 abuts between two connecting blocks 2 of adjacent combined modules 1, a large gap is formed between the two connected connecting blocks 2, so that some debris is stuck in the gap between the connecting blocks 2 during the conveyor belt transportation, affecting the normal operation of the conveyor belt; therefore, while keeping the widths between adjacent connecting blocks 2 in the same combined module 1 the same, the inner side of the outermost connecting block 2 in the combined module 1 is recessed inwards (such as Figure 6 As shown in point b in the middle, the recessed area is larger than the pin hole area, and the recessed depth is maintained equal to the width of the fixed rib 4, so that the recessed portion can provide sufficient accommodation space for the fixed rib 4; when the fixed rib 4 abuts between two adjacent connecting blocks 2, the fixed rib 4 is hidden in the recessed portion of the connecting block 2, thereby ensuring the limiting effect of the pin 302 and avoiding obvious gaps on the conveyor belt, thereby solving the accommodation problem of the fixed rib 4.

[0037] In order to prevent the connecting block 2 from being too thin after being recessed inward, and the connecting block 2 from being easily broken when the conveyor belt runs at high speed, the width of the connecting block 2 with the recess is increased, that is, the connecting block 2 at the outermost end of the combination module 1 is extended horizontally outward so that its width is greater than the width of the connecting block 2 in the middle of the combination module 1. Even after a recess of a certain depth is provided, the connecting block 2 can still have a certain thickness, thereby preventing the connecting block 2 from breaking and affecting the normal operation of the conveyor belt.

[0038] The working principle of this embodiment is as follows:

[0039] When assembling the conveyor belt, firstly, the connecting blocks 2 between the adjacent combined modules 1 are staggered and spliced ​​together, and the shaft 301 is passed through the pin hole of the connecting block 2. Then, the pins 302 are respectively inserted into the pin holes at both ends of the combined module 1. The end of the pin 302 with the fixing rib 4 is pushed into the pin hole of the outermost connecting block 2 of the combined module 1 by external force. The through hole at the fixing rib 4 makes the pin 302 have a certain elasticity, so that the fixing rib 4 passes through the pin hole of the outermost connecting block 2 and abuts between two adjacent connecting blocks 2 (such as Figure 4 As shown), at this time, the fixing rib 4 is completely accommodated in the recess of the outermost connecting block 2.

[0040] During the process of passing the fixing rib 4 through the pin hole, under the action of external force, the protrusion of the shaft rod 301 is stuck in the groove of the pin 302, so that the shaft rod 301 is connected with the pin 302 to form the through-shaft 3. At this time, when the fixing rib 4 abuts between two adjacent connecting blocks 2, the through-shaft 3 cannot move, thereby completing the splicing work of the combined module 1; when the combined module 1 needs to be disassembled and replaced, external force is applied to the through-shaft 3, and the pins 302 at both ends of the through-shaft 3 are respectively pushed out of the pin holes. After the pins 302 are removed, the shaft rod 301 can be pulled out, so as to realize the rapid disassembly and assembly of the through-shaft 3, facilitate the disassembly and assembly of the combined module 1 from the overall conveyor belt, and improve the assembly efficiency.

[0041] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
