[0050] The present application is described in detail below. Examples of embodiments of the present application are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components having the same or similar functions. In addition, if the detailed description of the known technology is not necessary for the features of the present application shown, it will be omitted. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0051] It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. It should also be understood that terms such as those defined in common dictionaries should be understood to have meanings consistent with their meanings in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

It should be further understood that the term "comprising" used in the specification of the present application refers to the presence of the features, integers, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof. It should be understood that when we refer to an element as being "connected" or "coupled" to another element, it may be directly connected or coupled to the other element, or there may be intermediate elements. In addition, "connected" or "coupled" as used herein may include wireless connections or wireless couplings. The term "and / or" used herein includes all or any units and all combinations of one or more associated listed items.

[0053] The inventors of this application have discovered through research that the chain belt of a chain conveyor can be composed of sequentially connected chain units. When the chain belt reciprocates, each chain unit is subjected to tension in the direction of motion. This tension is particularly pronounced when the chain belt is heavily loaded. If the chain units are insufficiently strong, they are susceptible to deformation under the tension. Once deformed, the chain unit's strength is further reduced, and the clearance gap increases, exacerbating wear. Consequently, existing chain units have a short lifespan and require frequent maintenance.

[0054] To extend the life of the chain plate unit, while maintaining the same material (i.e., strength) of the chain plate unit, one can consider increasing the permissible deformation space of the chain plate unit. This means improving the assembly accuracy of the chain plate unit and minimizing the possible clearance during the initial assembly phase to create space for possible permissible deformation of the chain plate unit. However, excessive assembly accuracy can lead to a surge in assembly difficulty, requiring high maintenance skills and time-consuming maintenance, which still makes it difficult to reduce the impact on production line efficiency.

[0055] The chain plate unit, chain plate belt and conveying equipment provided in this application are intended to solve the above technical problems of the prior art.

[0056] The following describes in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems with specific embodiments.

[0057] The embodiment of the present application provides a chain plate unit 100, the structural diagram of the chain plate unit 100 is as follows Figure 1-Figure 5 As shown, it includes: a chain unit block 110 and a reinforcement member 120.

[0058] The chain unit block 110 includes a unit body 111 and ear clips 112. The ear clips 112 are connected to opposite ends of the unit body 111 in the first direction and are respectively configured to be hinged to corresponding connecting rods 210. At least one side of the unit body 111 has a mounting groove 111a extending along the first direction.

[0059] At least a portion of the reinforcement member 120 is located in the installation groove 111 a , and both ends of the reinforcement member 120 are respectively used to be hinged to the corresponding connecting rod 210 .

[0060] In this embodiment, reinforcement members 120 are added at both ends for articulating with corresponding connecting rods 210. When the chain plate belt 200 performs a cyclic reciprocating motion, the reinforcement member 120 can bear at least part of the tension along the motion direction on the chain plate unit 100, thereby reducing or even completely eliminating the tension that the chain unit block 110 needs to bear, effectively reducing the probability of deformation of the chain unit block 110, ensuring strength, and also reducing the increase in fitting clearance, slowing down wear, improving wear resistance, and extending the life of the chain unit block 110, which is conducive to improving the operating efficiency of the production line.

[0061] Since the probability of deformation of the chain unit block 110 is effectively controlled, there is no need to increase the allowable deformation space of the chain unit block 110, that is, there is no need to improve the assembly accuracy of the chain unit block 110, but a larger assembly error can be allowed, thereby effectively reducing the assembly difficulty, reducing maintenance technical requirements, and shortening the maintenance cycle.

[0062] At least a portion of the reinforcement 120 is located within the mounting groove 111a of the chain unit block 110, that is, the chain plate unit 100 adopts a structure in which the reinforcement 120 is built into the chain unit block 110. Compared with an external structure in which the reinforcement 120 is arranged between adjacent chain unit blocks 110, the built-in reinforcement 120 is beneficial to strengthening the integrity between the reinforcement 120 and the chain unit block 110, and utilizing the reinforcement ribs to form a certain support for the chain unit block 110, that is, strengthening the load-bearing capacity of the chain unit block 110.

[0063] It should be noted that the first direction is substantially the same as the direction of reciprocating motion of the chain plate belt 200 formed by the chain unit blocks 110. For example, the first direction may be parallel to the reciprocating motion direction or may be at an angle less than 90°.

[0064] In some possible implementations, the chain unit block 110 is made of plastic.

[0065] In this embodiment, the chain unit block 110 is made of plastic material, which has the advantages of corrosion resistance, light weight, low noise, loose lubrication requirements, good anti-sticking properties, easy cleaning, and a wide temperature range, which is conducive to wide promotion.

[0066] In some examples, the chain unit block 110 may be made of PA6 (Polyamide 6) or POM (polyformaldehyde).

[0067] In some possible implementations, the reinforcement 120 is made of metal.

[0068] In this embodiment, the reinforcement 120 is made of metal, which can provide good strength on the one hand, and on the other hand is conducive to timely discharge of static electricity that may be generated between the components when the chain belt 200 performs reciprocating motion, thereby effectively improving the static electricity removal effect.

[0069] In some examples, the reinforcement 120 may be made of steel, aluminum alloy, or the like.

[0070] The inventors of this application have considered that in order to realize the structure in which the chain plate unit 100 adopts the reinforcement member 120 built into the chain unit block 110, the reinforcement member 120 needs to be stably located in the installation groove 111a of the chain unit block 110. To this end, this application provides the following three possible implementation methods for the chain plate unit 100:

[0071] In a first embodiment, if Figure 4 and Figure 5 As shown, the reinforcement member 120 has at least two limiting grooves 120a spaced apart from each other on one side facing the bottom of the installation groove 111a.

[0072] The bottom of the installation groove 111 a of the unit body 111 has a limiting protrusion 111 b that engages with the limiting groove 120 a.

[0073] In this embodiment, the limiting groove 120a of the reinforcement 120 and the limiting protrusion 111b at the bottom of the installation groove 111a are interlocked, which is conducive to convenient alignment when the reinforcement 120 is assembled to the installation groove 111a, and is also conducive to improving the stability of the reinforcement 120 in the installation groove 111a, reducing the probability of displacement of the reinforcement 120, and ensuring the integrity between the reinforcement 120 and the chain unit block 110.

[0074] The reinforcement member 120 has two or more limiting grooves 120a, which is conducive to achieving multi-point interlocking of the reinforcement member 120 with the bottom of the installation groove 111a at two or more points, and can improve the stability of the cooperation between the reinforcement member 120 and the installation groove 111a.

[0075] In some examples, the number of the limiting protrusions 111b at the bottom of the installation groove 111a can be the same as the number of the limiting grooves 120a of the reinforcement 120, that is, a one-to-one correspondence between the limiting protrusions 111b and the limiting grooves 120a is achieved, which can achieve stronger matching stability.

[0076] In other examples, the number of the limiting grooves 120a of the reinforcement 120 may be greater than the number of the limiting protrusions 111b at the bottom of the installation groove 111a. This helps to improve the compatibility of the reinforcement 120 to adapt to the structural limitations of different types of chain unit blocks 110.

[0077] In the second embodiment, based on the first embodiment, the unit body 111 may have a key structure 111 c for engaging with the reinforcement 120 .

[0078] like Figure 2 and Figure 3 As shown, the projection of the latch structure 111c on the plane where the bottom of the installation groove 111a is located is located between the projections of at least two limiting protrusions 111b on the plane where the bottom of the installation groove 111a is located.

[0079] In this embodiment, the key structure 111c provided on the unit body 111 of the chain unit block 110 can limit the displacement of the reinforcement 120 in the direction away from the bottom of the installation groove 111a, which is conducive to ensuring that the limiting groove 120a of the reinforcement 120 and the limiting protrusion 111b at the bottom of the installation groove 111a remain effectively engaged, that is, ensuring the assembly stability between the reinforcement 120 and the chain unit block 110.

[0080] In addition, the projection of the key structure 111c on the plane where the bottom of the installation groove 111a is located is located between the projections of at least two limiting protrusions 111b on the plane where the bottom of the installation groove 111a is located, which is conducive to forming a triangle between the card node of the key structure 111c on the reinforcement 120 and the connecting line between at least two fitting points between the reinforcement 120 and the bottom of the installation groove 111a, that is, realizing "three-point limitation", further enhancing the assembly stability between the reinforcement 120 and the chain unit block 110.

[0081] In some examples, the latch structure 111c is located at the opening of the mounting slot 111a and is used to latch with the side of the reinforcement member 120 away from the bottom of the mounting slot 111a. In this way, the latch structure 111c can be as far away from the bottom of the mounting slot 111a as possible, which helps to strengthen the aforementioned "three-point limit" limiting effect.

[0082] In a third embodiment, as Figure 4 As shown, the reinforcement member 120 includes a main body 121 and ear portions 122 connected to both ends of the main body 121 .

[0083] The ears 122 are respectively used to be hinged to the corresponding connecting rods 210 .

[0084] At least a portion of the limiting groove 120 a is formed on one side of the main body 121 facing the bottom of the installation groove 111 a and close to the ear portion 122 .

[0085] In this embodiment, at least part of the limiting grooves 120a of the reinforcement 120 are formed at a position close to the ear 122 of the main body 121, so that the spacing between at least part of the limiting grooves 120a can be increased, which is beneficial to improving the stability of the fit between the reinforcement 120 and the installation groove 111a.

[0086] The inventors of this application have considered that the chain unit blocks 110 need to be connected in series to form a chain plate belt 200, and the tension received by the chain unit blocks 110 is related to the connection method between adjacent chain unit blocks 110. Therefore, this application provides the following three possible implementation methods for the chain plate unit 100:

[0087] In a first embodiment, if Figure 2 As shown, the ear buttons 112 at the same end of the unit body 111 are arranged at intervals for interlaced cooperation with the ear buttons 112 of the adjacent unit body 111 .

[0088] In the chain unit block 110 of the present embodiment, the ear buckles 112 located at the same end of the unit body 111 are arranged at intervals. On the one hand, this is conducive to distributing the tension between adjacent chain unit blocks 110 and reducing the probability or degree of stress concentration. On the other hand, it is conducive to achieving staggered cooperation with the ear buckles 112 of adjacent unit bodies 111, which not only increases the contact points between adjacent chain unit blocks 110 and improves the cooperation stability, but also disperses and evenly distributes the force at each contact point, ensuring that the force of the chain unit block 110 is balanced, effectively reducing the probability of deformation of the chain unit block 110, and extending the service life of the chain unit block 110.

[0089] The inventors of this application have considered that the chain plates formed by connecting the chain plate units 100 in series usually achieve cyclic reciprocating motion under the drive of a drive mechanism, and at least some of the chain plate units 100 need to establish a driving connection with the drive mechanism. To this end, this application provides the following three possible implementation methods for the chain plate units 100:

[0090] In the first embodiment, at least one surface of the unit body 111 has meshing grooves 111 d arranged in an array, and the meshing grooves 111 d are used to mesh with the driving gear 300 .

[0091] In this embodiment, the meshing groove 111d of the chain unit block 110 in the chain plate unit 100 meshes with the driving gear 300 of the driving mechanism, thereby realizing the required driving connection between the chain plate unit 100 and the driving mechanism, and further realizing that the chain plate formed by the chain plate units 100 in series can perform cyclic reciprocating motion under the drive of the driving mechanism.

[0092] In a second embodiment, if Figure 2 and Figure 3As shown, at least one side of the unit body 111 has an array of meshing grooves 111 d and a weight-reducing groove 111 e , and the meshing groove 111 d is used to mesh with the driving gear 300 .

[0093] In this embodiment, the chain unit block 110 in the chain plate unit 100 not only has an engagement groove 111d for engaging with the driving gear 300 of the driving mechanism, but also has a weight reduction groove 111e for reducing weight. The weight reduction groove 111e can reduce the weight of the chain unit block 110 itself, thereby reducing the weight of the entire chain plate, which is conducive to using the driving force of the driving mechanism more to drive the material carried on the chain plate, thereby improving the efficiency of the conveying equipment.

[0094] It is understandable that this embodiment does not limit the specific shape of the weight-reducing groove 111 e . The weight-reducing groove 111 e can be provided in the area other than the engagement groove 111 d while ensuring the strength of the chain unit block 110 .

[0095] In some possible implementations, based on the aforementioned second implementation, such as Figure 2 and Figure 3 As shown, the mounting groove 111 a and the engaging groove 111 d are located on the same surface of the unit body 111 .

[0096] In this embodiment, the installation groove 111 a and the engagement groove 111 d are located on the same surface of the unit body 111 , which helps to ensure the flatness of the other surface of the unit body 111 and further facilitates the chain plate unit 100 to carry materials.

[0097] The inventors of this application have considered that, in the solution provided in the aforementioned embodiment of using the latch structure 111c to restrain the reinforcement member 120, the latch structure 111c needs to be formed on the unit body 111 of the chain unit block 110. To this end, this application provides the following possible implementations for the chain plate unit 100:

[0098] In this embodiment, if Figure 3 As shown, a portion of the partition structure between the installation slot 111a and the adjacent engagement slot 111d or weight-reducing slot 111e forms a key structure 111c, which is engaged with the reinforcement 120 to restrict the reinforcement 120 to the installation slot 111a.

[0099] In this embodiment, a partial partition structure between the installation groove 111 a and the adjacent engaging groove 111 d or the weight-reducing groove 111 e is fully utilized to form the key structure 111 c , which is conducive to full utilization of materials.

[0100] Specifically, two spaced apart holes and grooves can be opened on the partition structure, and each hole and groove extends from the opening of the mounting groove 111a to the bottom of the mounting groove 111a. The partition structure part between the two holes and grooves can form the main body of the card. The end of the main body of the card away from the bottom of the mounting groove 111a has a snap portion that is perpendicular or basically perpendicular to the main body of the card. The main body of the card and the snap portion together form a key structure 111c.

[0101] In one example, a portion of the partition structure between the mounting groove 111 a and the adjacent engaging groove 111 d forms a key structure 111 c .

[0102] In another example, a portion of the partition structure between the mounting groove 111 a and the adjacent weight-reducing groove 111 e forms a key structure 111 c .

[0103] In another example, a portion of the partition structure between the mounting slot 111a and the adjacent mounting slot 111a forms a latching structure 111c. In this case, the latching structure 111c may include two, each for retaining the reinforcement member 120 within the two mounting slots 111a. Alternatively, the latching structure 111c may be a single, with the end of the latching body of the latching structure 111c, away from the bottom of the mounting slot 111a, having two latching portions for retaining the reinforcement member 120 within the two mounting slots 111a.

[0104] Based on the same inventive concept, the embodiment of the present application provides a chain plate belt 200, the structural schematic diagram of the chain plate belt 200 is as follows: Figure 9 and Figure 10 As shown, it includes: any one of the chain plate units 100 provided in the above embodiments, a connecting rod 210 and a plug 220.

[0105] At least some of the chain plate units 100 are arranged sequentially along a first direction, and the ear buckles 112 of the chain unit blocks 110 and the ends of the reinforcement members 120 in adjacent chain plate units 100 in the first direction are respectively hinged to corresponding connecting rods 210. The plug 220 is fixedly connected to at least one end of the connecting rod 210.

[0106] In this embodiment, at least some of the chain plate units 100 arranged in sequence in the first direction are hinged and connected in series through the connecting rod 210 to form the chain plate belt 200, and a plug 220 is used to limit the end of the connecting rod 210 to prevent the connecting rod 210 from falling off.

[0107] In this embodiment, since the chain plate belt 200 includes any one of the chain plate units 100 provided in the aforementioned embodiments, the implementation principles and beneficial effects thereof are similar and will not be described in detail here.

[0108] Based on the same inventive concept, an embodiment of the present application provides a conveying device, which includes: any one of the chain belts 200 provided in the above embodiments, and a driving mechanism.

[0109] The driving mechanism is in transmission connection with at least part of the chain plate units 100 in the chain plate belt 200 .

[0110] In this embodiment, the driving mechanism provides the chain belt 200 with a driving force for reciprocating motion, thereby realizing the transportation of materials.

[0111] In this embodiment, since the conveying equipment includes any one of the chain belts 200 provided in the aforementioned embodiments, its implementation principles and beneficial effects are similar and will not be described in detail here.

[0112] In some possible implementations, the driving assembly includes: a driving gear 300 and a driving machine.

[0113] The output shaft of the driving machine is drivingly connected to the driving gear 300 .

[0114] The driving gear 300 is engaged with the engagement groove 111d of the chain unit block 110 in the chain plate unit 100. Figure 6 、 Figure 7 or Figure 8 shown.

[0115] In this embodiment, the driving machine provides driving force for driving the chain belt 200, and the driving gear 300 realizes the driving connection with the chain unit block 110 in the chain unit 100, thereby transmitting the driving force output by the driving machine to the chain belt 200, so that the chain belt 200 can perform a circular reciprocating motion to realize the transportation of materials.

[0116] In some examples, the driving gear 300 can be made of plastic.

[0117] In some examples, the driving machine may be an electric motor, a pneumatic motor, or any other power output device.

[0118] By applying the embodiments of the present application, at least the following beneficial effects can be achieved:

[0119] 1. The chain plate unit 100 is provided with reinforcement members 120 at both ends, which are respectively used to articulate with the corresponding connecting rods 210. When the chain plate belt 200 performs a cyclic reciprocating motion, the reinforcement member 120 can bear at least part of the tension in the direction of motion on the chain plate unit 100, thereby reducing or even completely eliminating the tension that the chain unit block 110 needs to bear, effectively reducing the probability of deformation of the chain unit block 110, ensuring strength, and reducing the increase in fitting clearance, thereby slowing down wear, improving wear resistance, and extending the service life of the chain unit block 110, which is conducive to improving the operating efficiency of the production line.

[0120] 2. Since the probability of deformation of the chain unit block 110 is effectively controlled, there is no need to increase the allowable deformation space of the chain unit block 110, that is, there is no need to improve the assembly accuracy of the chain unit block 110, but a larger assembly error can be allowed, thereby effectively reducing the assembly difficulty, reducing maintenance technical requirements, and shortening the maintenance cycle.

[0121] 3. At least a portion of the reinforcement member 120 is located within the mounting groove 111a of the chain unit block 110. That is, the chain plate unit 100 adopts a structure in which the reinforcement member 120 is built into the chain unit block 110. Compared with an external structure in which the reinforcement member 120 is disposed between adjacent chain unit blocks 110, the built-in reinforcement member 120 is beneficial for strengthening the integrity between the reinforcement member 120 and the chain unit block 110, and the reinforcement ribs provide a certain support for the chain unit block 110, that is, the load-bearing capacity of the chain unit block 110 is enhanced.

[0122] 4. The chain unit block 110 is made of plastic material, which has the advantages of corrosion resistance, light weight, low noise, loose lubrication requirements, good anti-sticking properties, easy cleaning, and a wide temperature range, which is conducive to wide promotion.

[0123] 5. The reinforcement 120 is made of metal, which can provide good strength on the one hand, and on the other hand is conducive to timely discharge of static electricity that may be generated between the components when the chain plate belt 200 performs reciprocating motion, thereby effectively improving the static elimination effect.

[0124] 6. The limiting groove 120a of the reinforcement member 120 and the limiting protrusion 111b at the bottom of the installation groove 111a are interlocked, which is conducive to convenient alignment when the reinforcement member 120 is assembled into the installation groove 111a, and is also conducive to improving the stability of the reinforcement member 120 in the installation groove 111a, reducing the probability of displacement of the reinforcement member 120, and ensuring the integrity between the reinforcement member 120 and the chain unit block 110.

[0125] 7. The key structure 111c provided on the unit body 111 of the chain unit block 110 can limit the displacement of the reinforcement 120 in the direction away from the bottom of the installation groove 111a. This is conducive to ensuring that the limiting groove 120a of the reinforcement 120 and the limiting protrusion 111b at the bottom of the installation groove 111a remain effectively engaged, that is, ensuring the assembly stability between the reinforcement 120 and the chain unit block 110.

[0126] 8. The projection of the key structure 111c on the plane where the bottom of the installation groove 111a is located is located between the projections of at least two limiting protrusions 111b on the plane where the bottom of the installation groove 111a is located. This is conducive to forming a triangle between the connecting line between the locking node of the key structure 111c on the reinforcement 120 and at least two fitting points between the reinforcement 120 and the bottom of the installation groove 111a, that is, realizing "three-point limitation", further enhancing the assembly stability between the reinforcement 120 and the chain unit block 110.

[0127] 9. The partial partition structure between the installation groove 111a and the adjacent engaging groove 111d or the weight-reducing groove 111e is fully utilized to form the key structure 111c, which is conducive to full utilization of materials.
