[0002] A conveying mechanism is a device used to transport materials from one place to another. It is composed of components such as a mobile platform, a conveyor belt, a drive device and a transmission device. Conveying mechanisms are widely used in industrial production and logistics transportation fields, and can effectively improve production efficiency and the speed of material transportation.

[0003] The existing conveying mechanism can drive the mobile platform to transport products through the conveyor belt, but the conveyor belt is generally exposed outside the conveyor mechanism. If the product accidentally detaches and falls during the conveying process, it may accidentally fall onto the conveyor belt. In serious cases, it may even fall into the gaps of the conveyor belt, causing the product to be easily stuck between the conveyor belt and the drive device. When moving, the conveyor belt will collide and rub against the product, causing damage to the conveyor belt, thereby increasing the failure rate and maintenance frequency of the conveying mechanism, seriously affecting the production progress.

[0004] In view of the above shortcomings, we need to develop a conveying mechanism with protective functions to meet the needs of the majority of users. Utility Model Content

[0005] In view of the above-mentioned problems that the conveyor belt of the existing conveying mechanism is exposed outside, the product is easy to fall into the gap of the conveyor belt, the conveyor belt is easy to be damaged, and the failure rate and maintenance frequency of the conveying mechanism are increased, the technical solution adopted by the utility model to solve the technical problems is:

[0008] Furthermore, the protective sheet is provided with a first blocking surface and a second blocking surface inclined toward both sides along the length direction, and the first blocking surface and the second blocking surface are inclined from top to bottom from the center of the protective sheet.

[0009] Furthermore, the first blocking surface and the second blocking surface are symmetrically arranged relative to the center of the protective sheet, and both the first blocking surface and the second blocking surface form an inclined angle a with a horizontal plane, and the angle range of the angle a is controlled between 0 degrees and 90 degrees.

[0010] Furthermore, the protection structure includes protection support frames respectively arranged on the outside of both ends of the conveying mechanism body, and the top of the protection support frame is cooperatively connected to the two ends of the bottom of the protection sheet.

[0011] Furthermore, the protective sheet adopts a thin-wall design, and the top of the protective support frame is provided with an inclined top structure that cooperates with the first blocking surface and the second blocking surface.

[0012] Furthermore, the protective support frame is provided with a connecting screw hole for easy positioning, and the protective sheet is provided with an adjustment hole corresponding to the position of the connecting screw hole, and the adjustment hole is a slotted hole structure.

[0013] Furthermore, a positioning groove for facilitating adjustment of the installation position is provided at the bottom of the protection support frame, and the positioning groove extends from the center of the protection support frame toward both sides of the conveyor belt.

[0016] The beneficial effects of the utility model are as follows:

[0017] 1. The utility model provides a protective structure for protecting the conveyor belt on the conveying mechanism body. The protective structure is located between the mobile platform and the conveyor belt. When the product falls from the mobile platform, it can be blocked by the protective structure and fall to other places, so as to prevent the product from falling into the gap inside the conveyor belt, thereby realizing the protective function, reducing the malfunction of the conveying mechanism and improving the production and transportation efficiency.

[0018] 2. The protective sheet of the utility model adopts a structure with both sides inclined downward and is arranged along the conveying track of the conveyor belt, fully covering the conveying path.

[0022] Figure 3 for Figure 2 AA section enlarged view. DETAILED DESCRIPTION

[0023] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, a conveying mechanism with a protective function includes a conveying mechanism main body 1200 and a protective structure 3400 for protecting the conveying mechanism main body 1200, the conveying mechanism main body 1200 includes a mobile platform 1 and a conveyor belt 2 for driving the mobile platform 1, the protective structure 3400 is located between the mobile platform 1 and the conveyor belt 2, and the protective structure 3400 is extended along the conveying track of the conveyor belt 2.

[0025] Optionally, the conveyor belt 2 can be made of different materials such as leather belt, steel belt, plastic belt, etc. as the transmission material of the conveying mechanism.

[0026] Specifically, in some embodiments, the mobile platform 1 is a carrier of the conveying mechanism main body 1200 for carrying products. The mobile platform 1 is installed on the conveyor belt 2. The side of the mobile platform 1 away from the conveyor belt 2 is a loading plane for placing products. The conveyor belt 2 drives the mobile platform 1 to move along the length direction of the conveying mechanism to realize the transportation of products. The conveyor belt 2 is a flexible and bendable transmission belt used to drive the mobile platform 1 to move. The conveying mechanism is provided with a driving device for providing conveying power and a transmission mechanism for driving the conveyor belt 2 to reciprocate. The driving device is generally composed of a driving motor and its output shaft. The transmission mechanism can transmit the power of the driving device to the conveyor belt 2. The conveyor belt 2 is wrapped around the outside of the transmission mechanism and the driving device. The driving device drives the conveyor belt 2 through the transmission mechanism to realize the function of the conveying mechanism to transport products.

[0027] More specifically, the protective structure 3400 is a protective component independently installed above the conveyor belt 2. The protective structure 3400 includes a protective component for preventing products from falling and a supporting component for installing the protective component. The protective component is arranged between the mobile platform 1 and the conveyor belt 2 along the conveying track of the conveyor belt 2. When the product falls from the mobile platform 1, it can be blocked by the protective component and fall to other places far away from the conveyor belt 2. The supporting component supports and lifts the protective component a certain distance away from the conveyor belt 2, so that the protective component will not contact the conveyor belt 2 when hit by the product to avoid damaging the conveyor belt 2. It can also prevent the product from colliding with the conveyor belt 2 and preventing the product from falling into the gap inside the conveyor belt 2, thereby realizing the function of protecting the conveyor belt 2, reducing the failure of the conveying mechanism, and improving production and transportation efficiency.

[0028] like Figure 1 and Figure 2 As shown, the protective structure 3400 includes a protective sheet 3 for protecting the conveyor belt 2. The protective sheet 3 is arranged above the conveyor belt 2. The length of the protective sheet 3 is greater than the moving stroke of the mobile platform 1, and the width of the protective sheet 3 is greater than the width of the conveyor belt 2.

[0029] Specifically, in some embodiments, the protective sheet 3 is a protective component of the protective structure 3400 for preventing products from falling. After being lifted by the supporting component, a certain distance between the protective sheet 3 and the upper side of the conveyor belt 2 is generated. The moving stroke of the mobile platform 1 is the distance range in which the mobile platform 1 moves back and forth in the conveying mechanism driven by the conveyor belt 2. The length of the protective sheet 3 is greater than the moving stroke of the mobile platform 1, so that the protective sheet 3 can cover the exposed surface of the conveyor belt 2 in the moving stroke. The width of the conveyor belt 2 is the maximum distance between the two sides away from the center of the conveyor belt 2 in the length direction. The width of the protective sheet 3 is greater than the width of the conveyor belt 2, so that the protective sheet 3 can more comprehensively cover the exposed surface of the conveyor belt 2 in the moving stroke, further preventing products from falling into the gap inside the conveyor belt, enhancing the protection effect, reducing the failure of the conveying mechanism, and improving production and transportation efficiency.

[0030] like Figure 3 As shown, the protection sheet 3 is provided with a first blocking surface 31 and a second blocking surface 32 inclined toward both sides along the length direction, and the first blocking surface 31 and the second blocking surface 32 are inclined from top to bottom from the center of the protection sheet 3 .

[0031] Specifically, in some embodiments, the protective sheet 3 is provided with a first stop surface 31 and a second stop surface 32 on the left and right sides along the length direction, respectively. The first stop surface 31 and the second stop surface 32 are located on the side of the protective sheet 3 away from the conveyor belt 2, and are used to guide the rebound direction of the product when it falls on the protective sheet 3. When the first stop surface 31 and the second stop surface 32 are planes parallel to the horizontal plane, the product may stay on the protective sheet 3 after falling. In order to prevent the product from staying on the protective sheet 3, the first stop surface 31 and the second stop surface 32 are respectively arranged in a direction perpendicular to the length direction of the protective sheet 3 and inclined from the center of the protective sheet 3 from top to bottom toward the outside, and the space between the first stop surface 31 and the second stop surface is reduced to form an arched structure with a high middle and low sides. After the product falls, it contacts the inclined The first stop surface 31 is affected by the tilt angle and rebounds to the lower side of the first stop surface 31. After the product falls, it contacts the tilted second stop surface 32 and rebounds to the lower side of the second stop surface 32 due to the tilt angle. The user can control the rebound distance and the falling position by adjusting the tilt angle. Baskets for product recovery can also be set on both sides of the length direction of the conveying mechanism to prevent the product from falling on the ground and damaging the product surface, and to prevent the product from falling and causing a chaotic environment. The first stop surface 31 and the second stop surface 32 are designed to be tilted on both sides, and the interval between the first stop surface 31 and the second stop surface 32 is narrowed, so that the product cannot stay on the protective sheet 3, so as to prevent the product from staying on the protective sheet 3 and hindering the reciprocating movement of the mobile platform 1.

[0032] like Figure 3As shown, the first blocking surface 31 and the second blocking surface 32 are symmetrically arranged relative to the center of the protective sheet 3, and both the first blocking surface 31 and the second blocking surface 32 form an inclined angle a33 with the horizontal plane, and the angle range of the angle a33 is controlled between 0 degrees and 90 degrees.

[0033] Specifically, in some embodiments, to facilitate manufacturing and design, the first stop surface 31 and the second stop surface 32 can be arranged on the protective sheet 3 in a symmetrical manner. The inclination angles of the first stop surface 31 and the second stop surface 32 are also the same due to the symmetrical arrangement, thereby avoiding the problem of inconvenience in manufacturing and processing due to differentiated design. The first stop surface 31 and the second stop surface 32 both form an angle a33 with the horizontal plane that is inclined at the same angle toward the outside. The angle a33 is designed to be an acute angle. More specifically, the angle range of the angle a33 is controlled to be between 20 degrees and 70 degrees for better results, which facilitates the control of the distance and position of the product rebounding after falling, and avoids the product staying on the protective sheet 3 to hinder the reciprocating movement of the mobile platform 1.

[0034] like Figure 1 and Figure 2 As shown, the protection structure 3400 includes protection support frames 4 respectively arranged on the outer sides of both ends of the conveying mechanism body 1200, and the top of the protection support frame 4 is connected to the two ends of the bottom of the protection sheet 3.

[0035] Specifically, in some embodiments, the protective support frame 4 is a supporting component of the protective structure 3400 for installing the protective sheet 3. The protective support frame 4 is respectively installed at the front and rear ends of the bottom of the protective sheet 3 along the length direction. The protective support frame 4 is located on the outer side of the conveying mechanism body 1200 at the head and tail ends of the conveying direction. The height of the protective support frame 4 is higher than the height of the side of the conveyor belt 2 used for conveying, so that the protective sheet 3 can be separated from the conveyor belt 2 during installation and a certain gap distance is generated, so that when the protective component is hit by the product, it will not contact the conveyor belt 2 to avoid damaging the conveyor belt 2, and it can also avoid collision between the product and the conveyor belt 2, and will not hinder the free movement of the mobile platform 1.

[0036] like Figure 1 and Figure 3 As shown, the protection sheet 3 adopts a thin-wall design, and the top of the protection support frame 4 is provided with an inclined top structure 41 that cooperates with the first blocking surface 31 and the second blocking surface 32.

[0037] Specifically, in some embodiments, the protective sheet 3 adopts a thin-wall design with a thickness controlled between 0.5 mm and 5 mm and formed by bending a thin plate, so that the upper and lower sides of the protective sheet 3 have the same shape. The thin-wall design is structurally adopted so that the protective sheet 3 can have a certain elasticity. When the product falls from above, the product contacts the upper surface of the protective sheet 3 and is rebounded to a farther position by the elastic rebound force, thereby preventing the product from staying on the surfaces of the first baffle surface 31 and the second baffle surface 32 due to friction and causing obstruction to the movement of the mobile platform 1. The inclined top structure 41 on the top of the protective support frame 4 can be set to a shape that cooperates with the structure on the lower side of the thin-walled protective sheet 3, so that the protective sheet 3 can fully fit the protective support frame 4 during installation, thereby improving the installation stability of the protective sheet 3 and improving the stability of the protective structure 3400.

[0038] like Figure 1 As shown, the protection support frame 4 is provided with a connection screw hole 42 for easy positioning, and the protection sheet 3 is provided with an adjustment hole 34 corresponding to the position of the connection screw hole 42, and the adjustment hole 34 is a slotted hole structure.

[0039] Specifically, in some embodiments, the connecting screw hole 42 is a threaded connecting hole of the protective support frame 4 for installing the protective sheet 3, and the adjusting hole 34 is an installation slot hole for the protective sheet 3 to be installed on the protective support frame 4. During installation, the user uses a screw or a bolt to pass through the adjusting hole 34 and threadably connect with the connecting screw hole 42 to lock or loosen the protective sheet 3. The adjusting hole 34 adopts a long slot hole structure, and the length direction of the slot hole structure is set in the same direction as the length direction of the protective sheet 3, so that the user can adjust the installation position of the protective support frame 4 according to actual conditions when installing the protective sheet 3. The protective support frame 4 can adjust the front and rear installation positions in the adjusting hole 34 to avoid other special-shaped structures on the installation surface, so that the installation of the protective structure 3400 is more adapted to the installation environment, thereby improving the installation stability and firmness of the protective structure 3400.

[0040] like Figure 1 As shown, a positioning groove 43 for adjusting the installation position is provided at the bottom of the protection support frame 4 , and the positioning groove 43 extends from the center of the protection support frame 4 toward the two sides of the conveyor belt 2 .

[0041] Specifically, in some embodiments, the adjustment slot 43 is located at the bottom of the protective support frame 4 and is an installation slot hole for adjusting the installation position of the protective support frame 4. The adjustment slot 43 adopts a long slot hole structure. The middle part of the protective support frame 4 is provided with a frame body cavity connected to the outside world. The frame body cavity is connected to the adjustment slot 43 so that the user can use tools to reach into the frame body cavity for installation. The length direction of the adjustment slot 43 is different from the conveying direction of the conveyor belt 2, or the length direction of the adjustment slot 43 is perpendicular to the conveying direction of the conveyor belt 2, so that the protective support frame 4 can adjust its own installation position through the adjustment slot 43. The installation position of the protective support frame 4 directly affects the position of the protective sheet 3 blocking the top of the conveyor belt 2. Therefore, the adjustment slot 43 is specially designed to adjust the range of the blocking coverage, and the blocking position is adjusted according to actual conditions, so as to further expand the protection range of the protective structure 3400, improve the flexibility of the protective structure 3400, and achieve the effect of flexible and detachable connection of the protective structure 3400.

[0042] like Figure 1 and Figure 3 As shown, the mobile platform 1 is provided with an avoidance structure for avoiding the protective structure 3400, and the avoidance structure is provided with an avoidance opening 11 for the protective sheet 3 to pass through, the inner diameter width of the avoidance opening 11 is greater than the width of the protective sheet 3, and the inner diameter height of the avoidance opening 11 is greater than the height of the protective sheet 3.

[0043] Specifically, in some embodiments, in order not to affect the normal use of the conveying function and the protection function, an avoidance structure for the air avoidance protection structure 3400 is opened at the bottom of the mobile platform 1. The avoidance structure adopts a hollow structure connected to the outside and is provided with an avoidance hole 11 for the protective sheet 3 to pass through. The avoidance holes 11 are respectively located on the front and rear sides of the mobile platform 1 along the conveying direction. The avoidance holes 11 on both sides are connected to each other to form a channel for the protective sheet 3 to pass through. Optionally, the avoidance holes 11 can adopt a circular or polygonal structure. The inner diameter width of the avoidance hole 11 is greater than the total width of the protective sheet 3 to leave space for placing and adjusting the protective sheet 3. The inner diameter height of the avoidance hole 11 is greater than the height of the protective sheet 3 to leave space for adjusting the installation height of the protective sheet 3. With such a design, it is convenient for the protective sheet 3 to pass through the avoidance hole 11 smoothly, and it is convenient for the mobile platform 1 to move smoothly on the conveying mechanism body 1200.

[0044] like Figure 1 and Figure 2 As shown, a platform cavity 12 is provided in the middle of the avoidance structure for easy installation and maintenance. The platform cavity 12 is connected to the outside and the avoidance opening 11 , and the mobile platform 1 is connected to the conveyor belt 2 through the bottom of the platform cavity 12 .

[0045] Specifically, in some embodiments, the platform inner cavity 12 is staggered and penetrated to the side other than the conveying direction, so that the user can enter the bottom of the platform inner cavity 12 from the penetrated side for installation, and the user can use screws or bolts to pass through the bottom of the platform inner cavity 12 to detachably connect the mobile platform 1 to the side of the conveyor belt 2 for carrying and conveying. When the product accidentally falls from the mobile platform 1, the product contacts the upper surface of the protective sheet 3 and is elastically rebounded to a farther position. Even if it falls into the platform inner cavity 12, it can fall out from the staggered side of the platform inner cavity 12, thereby reducing the chance of the product getting stuck in the platform inner cavity 12 and damaging the conveyor belt 2, avoiding collision between the product and the conveyor belt 2, and not hindering the free movement of the mobile platform 1.

[0046] like Figures 1 to 3 As shown, the specific implementation of Example 1 of the utility model is as follows:

[0047] During installation, the conveyor belt 2 is installed on the outer side of the driving device and the transmission mechanism on the conveying mechanism body 1200, and the mobile platform 1 is installed on the belt surface of the conveyor belt used for carrying and conveying. The user inserts screws or bolts into the platform inner cavity 12 and passes through the bottom of the platform inner cavity 12 to detachably connect the mobile platform 1 to the conveyor belt 2. The avoidance hole 11 is set toward the conveying direction of the conveyor belt 2. One end of the protective sheet 3 passes through the avoidance hole 11 and extends into the platform inner cavity 12, and extends from the avoidance hole 11 on the other side. Protective support frames 4 are used to erect the protective sheet 3 on both ends of the length direction on the conveyor. Above the belt 2, the first stop surface 31 and the second stop surface 32 are matched and placed on the inclined roof structure 41. The user passes the screws or bolts through the adjustment holes 34 and threadedly connects them with the connecting screw holes 42. After adjusting the position so that the protective sheet 3 can cover the conveyor belt 2, tighten the screws or bolts to fix the position of the protective sheet 3 on the protective support frame 4, and then fine-tune the positions of the protective support frames 4 at both ends according to actual conditions so that the protective sheet 3 can fully cover the top of the conveyor belt 2. Finally, the user passes the screws or bolts through the adjustment slots 43 to fix the installation position of the protective support frame 4, and completes the installation of the conveying mechanism.

[0048] The first blocking surface 31 and the second blocking surface 32 of this embodiment both form an inclined angle a with the horizontal plane, and the angle a is 15 degrees. The angle a of 15 degrees ensures that the product is guided to fall in an inclined direction, and does not occupy too much vertical space above the conveyor belt 2, and does not affect the overall thickness of the conveyor mechanism body 1200;

[0049] During use, the driving device drives the conveyor belt 2 to operate through the transmission mechanism, and the conveyor belt 2 drives the mobile platform 1 to move along the conveying track. When the product accidentally falls from the mobile platform 1, the product contacts the first blocking surface 31 or the second blocking surface 32 on the upper side of the protective sheet 3 and is rebounded to a farther position by the elastic rebound force of the protective sheet 3 itself, thereby achieving the effect of protecting the conveyor belt 2. The mobile platform 1 moves freely on the protective sheet 3 through the avoidance hole 11, thereby ensuring the normal use of the conveying function, preventing the product from staying on the protective sheet 3, and further guiding the direction in which the product falls, which is conducive to collecting the fallen products and preventing the products from falling into the gap inside the conveyor belt 2, thereby enhancing the protection effect, reducing the failure of the conveying mechanism, and improving the production and transportation efficiency.

[0050] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
