Description
Technical Field
[0001] This utility model relates to the field of conveyor belt technology, and in particular to a modular conveyor belt for sorting chains. Background Technology
[0002] Modular conveyor belts are made by thermoforming plastic into semi-finished modules, which are then assembled into modules according to requirements and installed on conveyors to carry and transport materials. Modular conveyor belts have good lateral stability, good physical and chemical properties, and reasonable economic applicability, making them suitable for food processing, fruit grading, packaging lines, aquatic product processing lines, frozen product production lines, battery manufacturing, beverage manufacturing, canning industry, agriculture, chemical industry, electronics industry, etc.
[0003] Patent CN220097474U discloses a modular conveyor belt with perforated flat panels, including a first mounting block. Four sets of first fixing blocks are staggered on both sides of the first mounting block. A middle mounting block is movably mounted on the front of the first mounting block via a fixing rod. A second mounting block is movably mounted on the front of the middle mounting block via a fixing rod. The first mounting block has first heat dissipation holes inside, and a first anti-slip layer is installed on its surface. This patent addresses the problem that, during use, the connecting parts of modular conveyor belts with identical components will sink due to excessive pressure when transporting heavy objects, and it also provides significant friction to prevent slippage during cargo transport. However, it does not address the issue of reducing frictional resistance between the sorted items and the conveyor belt in sorting scenarios where the direction of movement needs to be changed and the items need to detach from the conveyor belt. Utility Model Content
[0004] To optimize the sorting process and facilitate changing the direction of movement of sorted items so that they can be removed from the conveyor belt, this utility model provides a modular conveyor belt for sorting chains.
[0005] This utility model provides a modular conveyor belt for sorting chains, comprising:
[0006] Two adjacent chain links are provided with connecting protrusions on both sides of the chain link. The connecting protrusions are provided with connecting holes along the length of the chain link. A connecting rod is provided in the connecting hole. The chain link is provided with multiple through holes. A rolling mechanism is provided in the through holes. The rolling mechanism is detachably installed in the through holes. The rolling mechanism protrudes from the plane of the item carried by the chain link. The rolling direction of the rolling mechanism is perpendicular to the conveying direction of the conveyor belt.
[0007] Furthermore, the rolling mechanism includes a cylindrical roller connected in a through hole via a rolling shaft.
[0008] Furthermore, the roller is provided with first bushings at both ends, the rolling shaft is placed inside the first bushing and is clearance-fitted with the inner hole of the first bushing, and the outer periphery of the first bushing is formed with a rib, which is interference-fitted with the roller.
[0009] Furthermore, the first bushing has a limiting post protruding from the plane of the roller end, the limiting post has an end face, and the end face is attached with an annular metal sheet.
[0010] Furthermore, a groove is provided on one side of the chain link block, and a first rolling groove for the rolling shaft to rotate is formed in the groove. A closing block is provided on the groove, and a second rolling groove is provided on the closing block opposite to the first rolling groove. The first rolling groove and the second rolling groove cooperate to form a slot hole for the rolling shaft to rotate.
[0011] Furthermore, a second bushing is accommodated in the slot, and two opposing limiting pins are formed on the outer wall of the second bushing. A first limiting pin hole is formed in the groove, and a second limiting pin hole is formed on the sealing block. The two limiting pins are respectively inserted into the first limiting pin hole and the second limiting pin hole.
[0012] Furthermore, the sealing block has ear strips formed on both sides, the groove has ear grooves formed on both sides to cooperate with the ear strips, the sealing block and the groove are interference fit, and the sealing block has a notch.
[0013] Furthermore, the connecting rod has sealing grooves at both ends, and plugs are movably installed in the sealing grooves. Each plug includes a sealing cap and a protrusion connected to one side of the sealing cap. The protrusion has a barb, and the barb is interference-fitted with the sealing groove.
[0014] Furthermore, the roller surface is formed with strip-shaped friction stripes, the direction of which is consistent with the direction of the rolling axis.
[0015] In summary, this utility model has the following beneficial technical effects:
[0016] 1. The present invention proposes a modular conveyor belt for sorting chains, which sets a rolling mechanism in the through hole of the chain link block, and the rolling direction of the rolling mechanism is perpendicular to the conveying direction of the conveyor belt. When the sorted items need to change their movement direction and leave the conveyor belt, the rolling mechanism can effectively reduce the frictional resistance between the sorted items and the conveyor belt, so that they can change their movement direction more smoothly and improve sorting efficiency. It is especially suitable for sorting scenarios where the movement trajectory of the items is required.
[0017] 2. The present invention proposes a modular conveyor belt for sorting chains. The rolling mechanism uses cylindrical rollers connected to through holes via rolling shafts. The first bushings at both ends of the rollers are clearance-fitted with the rolling shafts to facilitate the rotation of the rolling shafts. At the same time, the protruding ribs on the outer periphery of the first bushings are interference-fitted with the rollers to ensure the firm connection between the rollers and the first bushings. The grooves, closing blocks, and corresponding rolling grooves and second bushings provided on the chain links ensure that the second bushings are securely fixed in the rolling grooves. This allows for detachable installation of the rollers, and the rolling mechanism can be added as needed.
[0018] 3. The limiting post on the first bushing of this utility model and the annular metal sheet attached to its end face play a good role in limiting and reducing friction, avoiding friction between the end of the roller and the inner wall of the through hole during rotation, which would affect the rolling of the roller and extend the service life of the rolling mechanism.
[0019] 4. The plug design at both ends of the connecting rod of this utility model prevents the connecting rod from coming out of the connecting hole during use, ensuring the stability of the connection between adjacent chain links. The striped friction stripes on the surface of the roller can increase the friction between the roller and the sorted items to a certain extent, preventing the items from shifting position due to excessive sliding during the conveying process. At the same time, it increases the friction between the roller and the items when they leave the conveyor belt, allowing the items to leave the conveyor belt smoothly. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.
[0030] Example 1
[0031] Reference Figure 1 This embodiment of a sorting chain module conveyor belt includes: two adjacent chain links 1, each chain link 1 having a connecting protrusion 102 on both sides, the connecting protrusion 102 having a connecting hole 103 extending through the chain link 1 along its length, the connecting hole 103 having a connecting rod 7 inside, the chain link 1 having multiple through holes 104, the through holes 104 having a rolling mechanism 2 inside, the rolling mechanism 2 being detachably installed in the through holes 104, the rolling mechanism 2 protruding from the plane of the items carried by the chain link 1, and the rolling direction of the rolling mechanism 2 being perpendicular to the conveying direction of the conveyor belt.
[0032] Reference Figure 2 The rolling mechanism 2 includes a cylindrical roller 201, which is connected to the through hole 104 via a rolling shaft 202.
[0033] The chain link 1 is injection molded from high-strength engineering plastic. This material has good wear resistance and can ensure structural strength. The roller 201 and the link block bear the load of the conveyed items. When it is necessary to change the direction of movement of the items so that they can be removed from the conveyor belt, an external force perpendicular to the transport direction can be applied to the items, or the roller 201 can be driven to rotate on the underside of the roller 201 to complete the sorting of the items. This greatly reduces the friction coefficient between the items and the conveyor belt along the vertical transport direction.
[0034] Reference Figure 3 The roller 201 has a first bushing 3 at both ends. The rolling shaft 202 is placed inside the first bushing 3 and is clearance-fitted with the inner hole of the first bushing 3. The outer periphery of the first bushing 3 is formed with a rib 301, and the rib 301 is interference-fitted with the roller 201.
[0035] The first bushing 3 has a limiting post 302 that protrudes from the plane of the end of the roller 201.
[0036] The limiting post 302 has an end face, and a circular metal sheet 303 is attached to the end face.
[0037] The first bushing 3 is integrally injection molded from engineering plastic, ensuring that the rolling shaft 202 can rotate flexibly within the bushing while preventing excessive radial clearance that could cause the roller 201 to wobble. The protruding ribs 301 on the outer periphery of the bushing are formed by stamping, fitting tightly with the inner hole of the roller 201 to form a reliable interference fit, preventing relative displacement between the bushing and the roller 201. The length of the limiting post 302 is generally between 0.5 and 1 cm. The metal sheet 303 on its end face is made of wear-resistant stainless steel and is fixed to the end face of the limiting post 302 by adhesive bonding. The thickness of the metal sheet 303 is approximately 0.5 mm, which effectively prevents the limiting post 302 from wearing when in contact with the wall of the through hole 104, thus preventing it from affecting the rotation of the roller 201.
[0038] The first bushing 3 can be made of metal, and there is no need to attach a circular metal piece 303.
[0039] Reference Figure 4 The chain link block 1 has a groove 4 on one side, and a first rolling groove 401 for the rolling shaft 202 to rotate is opened in the groove 4. A closing block 5 is provided on the groove 4, and a second rolling groove 501 opposite to the first rolling groove 401 is provided on the closing block 5. The first rolling groove 401 and the second rolling groove 501 cooperate to form a slot hole for the rolling shaft 202 to rotate.
[0040] The depth of the groove 4 is half the thickness of the connecting block. The first rolling groove 401 is semi-circular in shape, and its radius matches the radius of the rolling shaft 202, ensuring that the rolling shaft 202 rotates smoothly in the groove without significant shaking.
[0041] Reference Figure 5 and Figure 6 The slot contains a second bushing 6, and the outer wall of the second bushing 6 has two opposing limiting pins 601. The groove 4 has a first limiting pin hole 402, and the sealing block 5 has a second limiting pin hole 502. The two limiting pins 601 are respectively inserted into the first limiting pin hole 402 and the second limiting pin hole 502.
[0042] Reference Figure 4 and Figure 5 The sealing block 5 has ear strips 503 formed on both sides, and the groove 4 has ear grooves 403 formed on both sides to cooperate with the ear strips 503. The sealing block 5 and the groove 4 are interference fit, and the sealing block 5 is provided with a notch 504.
[0043] The sealing block 5 is made of the same material as the chain link block 1 and is manufactured using injection molding. The ear bar 503 is shaped like an inverted triangle, and its dimensions are tightly fitted with the ear groove 403. The interference fit ensures that the sealing block 5 can be firmly installed on the groove 4. The notch 504 can be removed by prying it open with a flat-head screwdriver. The design of the second rolling groove 501 is the same as that of the first rolling groove 401. The groove formed by the two provides stable rotational support for the rolling shaft 202, ensuring the smooth operation of the rolling mechanism 2. The limiting pin 601 is inserted into the first limiting pin hole 402 and the second limiting pin hole 502, so that the second bushing 6 is stable between the groove 4 and the sealing block 5.
[0044] Reference Figure 7 The connecting rod 7 has sealing grooves 701 at both ends, and a plug 8 is movably installed in the sealing groove 701. The plug 8 includes a sealing cap 801 and a protruding post 802 connected to one side of the sealing cap 801. The protruding post 802 is provided with a barb, and the barb is interference-fitted with the sealing groove 701.
[0045] The plug 8 is made of plastic, and the diameter of the sealing cap 801 is larger than the diameter of the connecting hole 103 to prevent the connecting rod 7 from coming off. The barb makes it easy to insert the sealing cap 801 into the sealing groove 701. After being inserted into the sealing groove 701, it fits tightly against the groove wall to form a reliable anti-detachment structure, preventing the plug 8 from accidentally falling off during the operation of the conveyor belt.
[0046] The surface of the roller 201 is formed with strip-shaped friction stripes, and the direction of the friction stripes is consistent with the direction of the rolling shaft 202.
[0047] During the operation of the modular conveyor belt, adjacent chain links 1 are tightly connected by connecting rods 7. The cooperation of connecting protrusions 102 and connecting holes 103, as well as the anti-detachment design of plugs 8, ensure the structural integrity and connection stability of the entire conveyor belt. When it is necessary to sort items on the conveyor belt, since the rolling direction of the rolling mechanism 2 is perpendicular to the conveying direction of the conveyor belt, and the rollers 201 protrude from the plane of the chain link 1 that carries the items, the items can smoothly change their direction of movement under a small external force, achieving accurate sorting. The rolling mechanism 2 adopts a detachable installation method, which allows staff to easily replace or repair components such as rollers 201 and bushings during equipment maintenance.
[0048] Example 2
[0049] Reference Figure 8 The difference between this embodiment and Embodiment 1 is that this embodiment provides another modular conveyor belt for sorting chains, wherein the rolling mechanism 2 includes three spherical rolling balls connected in series and connected in the through hole 104 via a rolling shaft 202. The rolling of the three balls reduces the frictional force of the items moving vertically along the conveyor belt.
[0050] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
