[0002] In automated production equipment such as tunnel ovens, a mesh belt conveyor for conveying products to be processed is usually provided, and the mesh belt tensioning structure is a common structure in the mesh belt conveyor, through which the mesh belt can be tensioned. If the mesh belt is not effectively tensioned during operation and becomes loose, the mesh belt and the conveyor wheel will slip, causing the mesh belt to shift, causing the products to be processed to slip or even fall on the mesh belt, which will seriously affect the operation and production of the equipment. Therefore, in the production and operation of automated production equipment, the mesh belt tensioning structure is a relatively important structure.

[0003] The existing mesh belt tensioning structure is usually assembled from a square seat outer spherical bearing, a spring and other mounting seat parts. The mesh belt tensioning structure completely relies on the elastic force of the spring to provide tension to the mesh belt. The existing mesh belt tensioning structure has many disadvantages. For example, the initial tensioning requires manual compression of the spring. Due to the high hardness of the spring, it will cause inconvenience in operation and there is a risk of injury during the operation of the operator; the tensioning force of the mesh belt tensioning structure cannot be accurately estimated; during the operation of the equipment, it is impossible to accurately know whether the mesh belt is tensioned, etc. Utility Model Content

[0037] The utility model provides a mesh belt tensioning structure, which can be used in a mesh belt conveying device of an automated production equipment. Figures 1 to 3 A preferred embodiment of the mesh belt tensioning structure provided by the utility model is shown.

[0038] See also Figures 1 to 3 In this embodiment, the mesh belt tensioning structure 100 includes a mounting member 1, a tensioning shaft 2 and a driver 3. The tensioning shaft 2 is used to abut the tensioning mesh belt 200. The tensioning shaft 2 is slidably arranged on the mounting member 1 along a direction approaching the mesh belt 200 and a direction away from the mesh belt 200; the driver 3 is arranged on the mounting member 1, and the driver 3 is dynamically coupled to the tensioning shaft 2 so as to drive the tensioning shaft 2 to slide through the driver 3.

[0039] Specifically, the mesh belt conveyor includes a mesh belt 200, which is arranged on a mounting carrier (the mounting carrier may be a device wall of an automated production device, etc., and the following description will be made by taking the mounting carrier as a device wall as an example), and a mounting member 1 is arranged on the device wall, so that the mesh belt tensioning structure 100 can be fixedly arranged on the device wall through the mounting member 1. The specific style of the mesh belt 200 may not be particularly limited. For example, in this embodiment, the mesh belt 200 is formed by stainless steel strings passing through the rods in sequence, and then connected side by side through connecting pieces at both ends.

[0040] The tensioning shaft 2 is usually a round shaft, and the mesh belt tensioning structure 100 abuts against the mesh belt surface of the mesh belt 200 through the circumferential side surface of the tensioning shaft 2 to apply tensioning force to the mesh belt 200 to tension the mesh belt 200. The tensioning shaft 2 can slide relative to the mounting member 1, and the tensioning shaft 2 is located on one side of the mesh belt 200 in the sliding direction of the tensioning shaft 2, so that the tensioning shaft 2 can slide close to the mesh belt 200, and can also slide away from the mesh belt 200, so that the mesh belt tensioning force of the mesh belt tensioning structure 100 on the mesh belt 200 can be adjusted by sliding the tensioning shaft 2.

[0041] The sliding direction of the tensioning shaft 2 relative to the mounting member 1 is usually the radial direction of the tensioning shaft 2, and the axial direction of the tensioning shaft 2 is usually the width direction of the mesh belt 200. The axial direction of the tensioning shaft 2 and the width direction of the mesh belt 200 are defined below as both left and right, the sliding direction of the tensioning shaft 2 is front and back, and the part of the mesh belt 200 that abuts against the tensioning shaft 2 is located on the front side of the tensioning shaft 2.

[0042] The driver 3 may be a cylinder, an oil cylinder or a motor, etc., and the following description will take the driver 3 as an example of a cylinder. The driver 3 is used as a driving source of the mesh belt tensioning structure 100, and the tensioning shaft 2 can be driven to slide forward and backward through the driver 3. When the mesh belt 200 is in a tensioned state, if the tensioning shaft 2 is driven to slide forward through the driver 3, the tensioning force of the mesh belt tensioning structure 100 on the mesh belt 200 can be increased; if the tensioning shaft 2 is driven to slide backward through the driver 3, the tensioning force of the mesh belt tensioning structure 100 on the mesh belt 200 can be reduced.

[0043] The driver 3 is usually electrically connected to a controller such as a PLC, and the action of the driver 3 is controlled by the controller, which can ensure that the mesh belt 200 is in a tensioned state in real time, and the tensioning state of the mesh belt 200 can be known in real time through the digital display of the controller, which has high reliability. Among them, the controller can belong to the mesh belt tensioning structure 100, that is, the mesh belt tensioning structure 100 includes the controller; the controller can also not belong to the mesh belt tensioning structure 100, but the controller belongs to the mesh belt conveying device or the automated production equipment, that is, the mesh belt tensioning structure 100 does not include the controller, and the mesh belt conveying device or the automated production equipment includes the controller.

[0044] The mesh belt tensioning structure 100 of the utility model uses a driver 3 as a driving source, and drives the tensioning shaft 2 to slide through the driver 3, thereby realizing automatic drive tensioning of the mesh belt 200, replacing the existing manual mesh belt tensioning structure, and is more convenient to operate and has higher tensioning efficiency; and the driver 3 can be controlled by a controller to ensure that the mesh belt 200 is in a tensioned state in real time during the operation of the equipment, and the mesh belt tensioning force can also be accurately known.

[0045] When the mesh belt 200 in the tensioned state is running, the peripheral side surface of the tensioning shaft 2 contacts the mesh belt surface of the mesh belt 200. In order to reduce the friction resistance of the tensioning shaft 2 to the running mesh belt 200, optionally, refer to Figures 1 to 3 In the present embodiment, the tensioning shaft 2 is rotatably arranged on the mounting member 1 .

[0046] Specifically, the tension shaft 2 can rotate relative to the mounting member 1 along the axis in the width direction of the mesh belt 200 (i.e., the axial direction of the tension shaft 2). When the mesh belt 200 in the tensioned state is running, the mesh belt 200 can drive the tension shaft 2 to rotate along the axis in the left and right upward direction, so that rolling contact is formed between the mesh belt 200 and the tension shaft 2, thereby reducing the friction resistance of the tension shaft 2 to the running mesh belt 200.

[0047] The tensioning shaft 2 and the driver 3 are both arranged on the mounting member 1. The specific arrangement of the mounting member 1 can be set according to the actual situation. For example, the mounting member 1 can be designed with an integrated mounting seat or the like. Figures 1 to 3 In the present embodiment, two mounting members 1 are provided. The two mounting members 1 are respectively located on both sides of the mesh belt 200 in the axial direction of the tensioning shaft 2 , and both ends of the tensioning shaft 2 are respectively provided on the two mounting members 1 .

[0048] Specifically, the two mounting members 1 are respectively disposed on the left and right sides of the mesh belt 200 , and the left and right ends of the tensioning shaft 2 are respectively disposed on the two mounting members 1 in a rotatable and slidable manner.

[0049] For further information, see Figures 1 to 3 In this embodiment, the mounting member 1 is a mounting plate.

[0050] For example, the mounting member 1 may be a trapezoidal plate, etc., with bolt mounting holes provided on the mounting member 1, and bolt holes provided on the equipment wall, so that the mounting member 1 is fixed to the equipment wall by bolts, and may also be reinforced by welding to ensure the connection strength between the mounting member 1 and the equipment wall. The following will take the mounting member 1 as a mounting plate as an example, and the plate surfaces of the two mounting members 1 are opposite to each other in the left and right directions.

[0051] Optionally, see Figures 1 to 3In this embodiment, a sliding groove 12 extending along the sliding direction of the tensioning shaft 2 is provided on the mounting member 1 corresponding to the tensioning shaft 2, and the sliding groove 12 forms a guiding fit with the tensioning shaft 2 in the sliding direction of the tensioning shaft 2.

[0052] Specifically, a sliding groove 12 extending along the front-to-back direction is provided on the plate surface where the two mounting parts 1 are close to each other, and the left end and the right end of the tensioning shaft 2 respectively extend into the sliding grooves 12 on the two mounting parts 1, so that the two sliding grooves 12 can play a role of sliding guidance for the tensioning shaft 2 in the front-to-back and upward directions.

[0053] See also Figures 1 to 3 An axial limiting mechanism 9 is usually provided between the tensioning shaft 2 and the mounting member 1 so as to limit the tensioning shaft 2 and the mounting member 1 in the axial direction of the tensioning shaft 2 through the axial limiting mechanism 9 .

[0054] There are many specific ways to set the axial limit mechanism 9. For example, the axial limit mechanism 9 can be a limit nut set on the tensioning shaft 2. Figures 1 to 3 In this embodiment, the sliding groove 12 passes through the mounting member 1, and the axial limiting mechanism 9 includes an axial end baffle 91 and a bolt 92. The axial end baffle 91 is located on the side of the mounting member 1 away from the mesh belt 200. The tail end of the bolt 92 passes through the axial end baffle 91 and extends into the sliding groove 12 and is threadedly connected to the end face of the tensioning shaft 2.

[0055] Specifically, the tensioning shaft 2 can be a solid shaft, and bolt holes that threadably match the bolts 92 are provided on both end faces of the tensioning shaft 2. The shaft end baffle 91 can be a flat cover, and a bolt mounting hole for the bolts 92 to pass through is provided on the shaft end baffle 91. The two shaft end baffles 91 are respectively installed at the two ends of the tensioning shaft 2 through two bolts 92, and the tensioning shaft 2 can be limited in the axial direction through the two shaft end baffles 91. Since the axial limiting mechanisms 9 are provided at both ends of the tensioning shaft 2, the tensioning shaft 2 will not move left and right during the operation of the equipment.

[0056] In order to reduce the friction resistance of the tensioning shaft 2 during the sliding process, optionally, refer to Figures 1 to 3 In this embodiment, a rolling member 7 is provided on the tensioning shaft 2 , and the rolling member 7 is provided on the mounting member 1 so as to be able to roll along the sliding direction of the tensioning shaft 2 .

[0057] Specifically, the rolling member 7 is mounted on the tensioning shaft 2, and the rolling member 7 can rotate relative to the tensioning shaft 2 along the axial axis of the tensioning shaft 2. The tensioning shaft 2 abuts against the mounting member 1 through the rolling member 7, so that the rolling member 7 can roll back and forth on the mounting member 1, thereby driving the tensioning shaft 2 to slide back and forth through the rolling member 7. In this way, arranging the rolling member 7 on the tensioning shaft 2 can reduce the friction resistance of the tensioning shaft 2 during the sliding process, so that the tensioning force applied by the tensioning shaft 2 can act more effectively on the mesh belt 200.

[0058] For further information, see Figures 1 to 3 In this embodiment, rolling elements 7 are provided at both ends of the tensioning shaft 2 .

[0059] Specifically, two rolling members 7 are respectively provided at the two ends of the tensioning shaft 2 corresponding to the two mounting members 1. The tensioning shaft 2 can be supported by the two rolling members 7 so that the tensioning shaft 2 can slide smoothly back and forth without tilting.

[0060] Optionally, see Figures 1 to 3 In this embodiment, the rolling element 7 is a rolling bearing.

[0061] Specifically, two rolling bearings are respectively provided at the left and right ends of the tensioning shaft 2, and the two rolling bearings form two rolling elements 7. The use of rolling bearings instead of the outer spherical bearings with square seats in the existing mesh belt tensioning structure can reduce the friction resistance of the tensioning shaft 2 during movement, so that the tensioning force applied by the tensioning shaft 2 can act more effectively on the mesh belt 200.

[0062] Optionally, see Figures 1 to 3 In this embodiment, a boss 11 extending along the sliding direction of the tensioning shaft 2 is provided on the mounting member 1 corresponding to the rolling member 7, and the rolling member 7 is rotatably disposed on the boss 11.

[0063] Specifically, two bosses 11 extending in the front-to-back direction are respectively provided on the plate surfaces of the two mounting members 1 close to each other, and the two bosses 11 are respectively located at the bottom of the two mounting members 1. The two bosses 11 are respectively provided corresponding to the two rolling members 7, and each boss 11 is located at the lower side of a corresponding rolling member 7. Each rolling member 7 can roll forward and backward along a corresponding boss 11. Thus, the bosses 11 provided on the mounting members 1 can play a role in rolling guide for the rolling members 7 in the front-to-back and upward directions.

[0064] The mesh belt tensioning structure 100 drives the tensioning shaft 2 to slide forward and backward through the driver 3, and the driver 3 may be provided with one or more. For example, the driver 3 may be provided with one, and the one driver 3 is provided on a plate surface of a mounting member 1 close to the mesh belt 200, and the one driver 3 is connected to one end of the tensioning shaft 2 by power coupling; the driver 3 may also be provided with two, and the two drivers 3 are respectively provided on two plates of two mounting members 1 close to each other, and the two drivers 3 are respectively connected to the two ends of the tensioning shaft 2 by power coupling.

[0065] Optionally, see Figures 1 to 3 In the present embodiment, two drivers 3 are provided, and the two drivers 3 are respectively connected to the two ends of the tensioning shaft 2 by power coupling.

[0066] Specifically, the two drivers 3 synchronously apply driving force to the left and right ends of the tensioning shaft 2, so that the force on the tensioning shaft 2 is more balanced, which is conducive to the smooth forward and backward sliding of the tensioning shaft 2. The following is an example in which two drivers 3 are provided and the two drivers 3 are respectively connected to the two ends of the tensioning shaft 2 by power coupling.

[0067] A transmission mechanism is usually provided between the driver 3 and the tensioning shaft 2 to drive the tensioning shaft 2 to slide forward and backward through the transmission mechanism, so as to avoid the problem that the driver 3 applies too much driving force to the tensioning shaft 2. Figures 1 to 3 In this embodiment, a chain transmission mechanism 4 is provided between the driver 3 and the tensioning shaft 2, so that the driver 3 drives the chain transmission mechanism 4 to drive the tensioning shaft 2 to slide.

[0068] Specifically, two chain transmission mechanisms 4 are provided, and the two drivers 3 are connected to the left end and the right end of the tensioning shaft 2 through the two chain transmission mechanisms 4 respectively. The chain transmission mechanism 4 is provided between the driver 3 and the tensioning shaft 2, which can not only avoid the problem of excessive driving force applied by the driver 3 to the tensioning shaft 2, but also help to improve the accuracy of sliding adjustment of the tensioning shaft 2. In this way, the mesh belt tensioning structure 100 adopts a more flexible and lightweight chain transmission mechanism 4 to replace the compression spring in the existing mesh belt tensioning structure, which can make the operation of the tensioning mesh belt 200 more convenient.

[0069] For further information, see Figures 1 to 3 In this embodiment, the chain transmission mechanism 4 includes a sprocket 41 and a chain 42. The sprocket 41 is rotatably arranged on the mounting member 1 along the axial axis of the tensioning shaft 2. The sprocket 41 is located on one side of the tensioning shaft 2 in the sliding direction. The chain 42 is meshed with the sprocket 41. The two ends of the chain 42 are respectively connected to the driving end of the driver 3 and the tensioning shaft 2, so that the driver 3 drags the chain 42 to drive the tensioning shaft 2 to slide.

[0070] Specifically, the sprocket 41 is rotatably arranged on the plate surface of the mounting member 1 close to the mesh belt 200 along the left-right upward axis, and the sprocket 41 is located at the front side of the sliding groove 12 on the mounting member 1. The middle part of the chain 42 is meshed with the sprocket 41, one end of the chain 42 is connected to the driving end of the driver 3, and the other end of the chain 42 is connected to the tensioning shaft 2. When the controller gives the cylinder extension signal to the driver 3, the driving end of the driver 3 drags the chain 42, and the chain 42 rotates by meshing with the sprocket 41. The end of the chain 42 connected to the tensioning shaft 2 will pull the tensioning shaft 2, and the rolling element 7 and the boss 11 cooperate to roll, so that the tensioning shaft 2 slides in the direction of tensioning the mesh belt 200, thereby tensioning the mesh belt 200.

[0071] One end of the chain 42 is connected to the driving end of the driver 3. Figures 1 to 3 In this embodiment, the driving end of the driver 3 is provided with a chain joint 31, and the driver 3 is connected to the chain 42 through the chain joint 31. The chain joint 31 can be provided in a cylindrical shape or the like, and a bolt hole is provided at one end of the chain joint 31 close to the driving end of the driver 3, so that the chain joint 31 can be threadedly connected to the driving end of the driver 3, and a connecting ring is provided at one end of the chain joint 31 away from the driving end of the driver 3, so that the chain joint 31 can be connected to the chain 42 through the connecting ring.

[0072] The other end of the chain 42 is connected to the tensioning shaft 2. As described above, the tensioning shaft 2 is rotatably arranged on the mounting member 1. When the mesh belt 200 is running, the mesh belt 200 can drive the tensioning shaft 2 to rotate. In order to avoid driving the chain 42 when the tensioning shaft 2 rotates, optionally, refer to Figures 1 to 3 In this embodiment, a connecting member 6 is provided on the tensioning shaft 2 , and the connecting member 6 is rotatable relative to the tensioning shaft 2 along the axial axis of the tensioning shaft 2 , and the tensioning shaft 2 is connected to the chain 42 through the connecting member 6 .

[0073] Specifically, the connecting member 6 is arranged in an annular shape, and the connecting member 6 is sleeved on the tensioning shaft 2. The connecting member 6 is usually located on the side of the rolling member 7 close to the mesh belt 200, and the connecting member 6 can rotate relative to the tensioning shaft 2 along the axial axis of the tensioning shaft 2. When the mesh belt 200 drives the tensioning shaft 2 to rotate relative to the mounting member 1, the connecting member 6 will not rotate relative to the mounting member 1.

[0074] The specific installation method of the connecting member 6 on the tensioning shaft 2 may not be particularly limited. Figures 1 to 3 In this embodiment, a slot is provided on the outer circumferential surface of the tensioning shaft 2 corresponding to the connecting member 6, and the connecting member 6 is mounted in the slot.

[0075] The specific shape of the connecting member 6 may not be particularly limited. For example, the connecting member 6 may be provided in a circular ring shape. Figures 1 to 3In this embodiment, the connecting member 6 is configured in a teardrop shape, and a through hole is provided on the connecting member 6 for the tensioning shaft 2 to pass through, and the small end of the connecting member 6 is connected to the chain 42.

[0076] As described above, two drivers 3 are provided. Similarly, two chain transmission mechanisms 4 are provided corresponding to the two drivers 3, so that the two ends of the tensioning shaft 2 are connected to the two drivers 3 through the two chain transmission mechanisms 4. In order to ensure that the two chain transmission mechanisms 4 can run synchronously, optionally, refer to Figures 1 to 3 In this embodiment, the mesh belt tensioning structure 100 also includes a sprocket shaft 5, which is rotatably arranged on the mounting member 1 along the axial axis of the tensioning shaft 2, and the sprockets 41 in the two chain transmission mechanisms 4 are respectively arranged at both ends of the sprocket shaft 5.

[0077] Specifically, the sprocket shaft 5 is usually a solid shaft, and the sprocket shaft 5 and the tensioning shaft 2 are spaced apart and arranged in parallel, the sprocket shaft 5 is located in front of the tensioning shaft 2, and the sprocket shaft 5 is located on the side of the mesh belt 200 away from the tensioning shaft 2. The sprocket shaft 5 is rotatably arranged on the mounting member 1 along the left-right axis, and the sprocket shaft 5 and the mesh belt 200 are spaced apart so that the sprocket shaft 5 does not contact the mesh belt surface of the mesh belt 200.

[0078] The two sprockets 41 are respectively arranged at the left and right ends of the sprocket shaft 5. The sprocket 41 and the sprocket shaft 5 can be two independent components, and then the sprocket 41 is fixed on the sprocket shaft 5 by screwing or other methods; the sprocket 41 and the sprocket shaft 5 can also be integrally formed. When the controller gives the cylinder extension signal to the driver 3, the driving end of the driver 3 drags the chain 42, and the chain 42 rotates the sprocket shaft 5 by meshing with the sprocket 41. The end of the chain 42 connected to the connecting member 6 will pull the tensioning shaft 2, and the rolling member 7 and the boss 11 will roll together, so that the tensioning shaft 2 slides in the direction of the tensioning of the mesh belt 200, thereby tensioning the mesh belt 200.

[0079] The left and right ends of the sprocket shaft 5 are rotatably disposed on two mounting members 1, respectively. Figures 1 to 3 In this embodiment, both mounting members 1 are provided with mounting holes for the sprocket shaft 5 to pass through, and a bearing seat 8 is provided on the plate surface of each mounting member 1 away from the mesh belt 200, corresponding to the mounting hole, and the left and right ends of the sprocket shaft 5 are respectively inserted into the bearing seats 8 on the two mounting members 1. The bearing seat 8 can be fixed on the mounting member 1 by bolts or the like.

[0080] The two drivers 3 are respectively fixedly arranged on two plates of the two mounting members 1 close to each other.
