Description

Technical Field

[0001] The present invention relates to the technical field of material handling, and particularly to a conveying device for plastic sheet conveying. Background Art

[0002] In recent years, conveying devices for plastic sheet conveying have played a crucial role in industrial production and logistics management. Through automated and continuous conveying systems, the time and labor intensity of manual handling can be reduced, the production process can be accelerated, the overall production efficiency can be improved, and a stable conveying system can avoid damage or deformation of plastic sheets caused by improper manual operation, especially when dealing with fragile, thin, or high-surface-requirement plastic sheets.

[0003] During the use of some existing conveying devices for plastic sheet conveying, it is usually necessary to manually add plastic sheets to the surface of the conveyor belt one by one. The speed of manual feeding is usually slow, and the placement position is inaccurate and the placement frequency is uneven, which may cause phenomena such as offset, overlap, or damage of plastic sheets during conveying, thereby affecting product quality and the accuracy of subsequent processing procedures. At the same time, after the plastic sheets are conveyed to a suitable position, manual stacking is usually required. Manual stacking is a highly repetitive and physically exhausting task, which is prone to causing worker fatigue and increasing the risk of work-related injuries, especially when dealing with large or heavy plastic sheets, the physical burden on workers is more obvious.

[0026] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the drawings of the specification.

[0027] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0028] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0029] Furthermore, the present invention is described in detail with reference to the schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally out of the general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, the three-dimensional spatial dimensions of length, width, and depth should be included in actual production. Example 1

[0030] Reference Figures 1 to 7 , which is the first embodiment of the present invention, provides a conveying device for conveying plastic plates. This device includes: The conveyor belt body 100 includes a support table 101, a fixed conveyor belt 102 fixedly connected to the top of the support table 101, a movable conveyor belt 103 arranged outside the fixed conveyor belt 102, and an adjustment assembly 104 for controlling the movement of the movable conveyor belt 103 in cooperation; It should be noted that the support table 101 is the base of the conveyor belt body 100, providing structural support to ensure the stability and safety of the equipment. The fixed conveyor belt 102 is used for continuously conveying plastic plates, maintaining a stable transportation speed and direction. The movable conveyor belt 103 can adjust its position according to needs to adapt to plastic plates of different sizes or shapes, improving flexibility.

[0031] The transportation mechanism 200 includes a bearing assembly 201 arranged outside the support table 101, a driving assembly 202 for driving the conveying of the plates in cooperation, a feeding assembly 203 for intermittently feeding the plates onto the surfaces of the fixed conveyor belt 102 and the movable conveyor belt 103, a lifting assembly 204 arranged on the side of the support table 101 away from the feeding assembly 203, and a stacking assembly 205 for stacking the plates in cooperation.

[0032] Specifically, the adjustment assembly 104 includes threaded rods 104a respectively fixedly installed on the inner walls of both sides of the support table 101 through bearings, internal threaded columns 104b threadedly connected to the outer surfaces of the threaded rods 104a, connection blocks 104c fixedly sleeved on the outer surfaces of the internal threaded columns 104b and used in cooperation with the movable conveyor belt 103, limit rods 104d fixedly connected to the inner wall of the support table 101 and used in cooperation with the connection blocks 104c, handwheels 104e fixedly installed at the penetrating ends of the threaded rods 104a, and synchronous belts 104f sleeved on the outer surfaces of the threaded rods 104a.

[0033] It should be noted that when dealing with plastic plates of different widths, the operator rotates the handwheel 104e. Through the cooperation of the handwheel 104a and the synchronous belt 104f, the two threaded rods 104a are driven to rotate synchronously, so that the internal threaded column 104b drives the connection block 104c and the movable conveyor belt 103 to move along the limit rod 104d, thereby adjusting the distance between the movable conveyor belt 103 and the fixed conveyor belt 102.

[0034] Furthermore, the loading component 201 includes a fixing frame 201a disposed outside the support platform 101, a material placing frame 201b fixedly connected to the top of the fixing frame 201a, a communicating groove 201c formed in the inner wall of the material placing frame 201b, a limiting guide rail 201d fixedly connected to the bottom of the material placing frame 201b, and a guiding plate 201e fixedly connected to the side of the material placing frame 201b close to the support platform 101.

[0035] It should be further noted that the material placing frame 201b is used to store plastic plates to be conveyed, ensuring the orderly arrangement of materials, and the guiding plate 201e is used to guide the plastic plates to smoothly transition from the material placing frame 201b to the fixed conveyor belt 102 and the movable conveyor belt 103.

[0036] Among them, the driving component 202 includes a first servo motor 202a adaptively installed outside the support platform 101, a spline shaft 202b fixedly connected to the output end of the first servo motor 202a through a coupling and used in cooperation with the fixed conveyor belt 102 and the movable conveyor belt 103, a first belt pulley 202c fixedly sleeved on the outer surface of the spline shaft 202b, a first belt 202d sleeved on the outer surface of the first belt pulley 202c, a second belt pulley 202e sleeved on the inner surface of the other end of the first belt 202d, a connecting rod 202f fixedly connected to the inner surface of the second belt pulley 202e, a third belt pulley 202g fixedly sleeved on the outer surface of the connecting rod 202f, a second belt 202h sleeved on the outer surface of the third belt pulley 202g, a fourth belt pulley 202i sleeved on the inner surface of the other end of the second belt 202h, and a connecting column 202j fixedly connected to the inner surface of the fourth belt pulley 202i. The outer end surface of the spline shaft 202b penetrates to the inner side of the support platform 101.

[0037] It should be explained that when the first servo motor 202a is started, it drives the spline shaft 202b and the first belt pulley 202c to rotate synchronously. The spline shaft 202b is in sliding contact with the inner surface of the drive shafts of the fixed conveyor belt 102 and the movable conveyor belt 103 through the spline structure on its outer surface, ensuring that its power can smoothly drive the fixed conveyor belt 102 and the movable conveyor belt 103 to move. At the same time, through the cooperation of the first belt pulley 202c and the first belt 202d, the second belt pulley 202e, the connecting rod 202f, and the third belt pulley 202g are driven to rotate. Then, through the cooperation of the third belt pulley 202g and the second belt 202h, the fourth belt pulley 202i and the connecting column 202j are driven to rotate synchronously.

[0038] Preferably, the feeding assembly 203 includes a pressing bump 203a fixedly installed on the outer end surface of the connecting column 202j, a hinge rod 203b hinged to the outer surface of the fixed frame 201a, a pressure-receiving disc 203c fixedly connected to the outer surface of the hinge rod 203b and used in cooperation with the pressing bump 203a, a slider 203d hinged to the inner surface of the spline shaft 202b, a pushing block 203e fixedly connected to the top of the slider 203d, a feeding roller 203f fixedly installed at the penetrating end of the connecting rod 202f, and a leveling roller 203g arranged above the feeding roller 203f.

[0039] It should be noted that a spring is fixedly connected to the outer surface of the hinge rod 203b, and the other end of the spring is fixedly connected to the outer surface of the material-releasing frame 201b. When the connecting column 202j drives the pressing bump 203a to rotate, the connecting rod 202f drives the feeding roller 203f to rotate synchronously. The protruding part of the pressing bump 203a squeezes the pressure-receiving disc 203c, causing the hinge rod 203b to rotate. While the hinge rod 203b drives the slider 203d to slide along the inner wall of the limit guide rail 201d, a pulling force is given to the spring. At the same time, the slider 203d drives the pushing block 203e to slide along the inner wall of the communication groove 201c. When the concave part of the pressing bump 203a rotates towards the direction close to the pressure-receiving disc 203c, the pressure-receiving disc 203c and the hinge rod 203b lose pressure, and the pressure-receiving disc 203c, the hinge rod 203b, the slider 203d and the pushing block 203e are reset synchronously by the reaction force of the spring, so that the pushing block 203e pushes the plastic plate in the material-releasing frame 201b between the feeding roller 203f and the leveling roller 203g. Then, through the cooperation of the feeding roller 203f and the leveling roller 203g, the plastic plate is conveyed to the guide plate 201e, and the plastic plate slides to the upper sides of the fixed conveyor belt 102 and the movable conveyor belt 103 through the guide plate 201e.

[0040] During use, the first servo motor 202a is started, and the spline shaft 202b is driven to rotate through the coupling. The spline shaft is in sliding contact with the inner surfaces of the drive shafts of the fixed conveyor belt 102 and the movable conveyor belt 103 through the spline structure on its outer surface, ensuring stable power transmission and enabling the fixed conveyor belt and the movable conveyor belt to run synchronously. At the same time, the first pulley 202c on the spline shaft rotates accordingly, drives the second pulley 202e to rotate through the first belt 202d, and further drives the connecting rod 202f and the third pulley 202g to rotate. The third pulley drives the fourth pulley 202i and the connecting column 202j to rotate synchronously through the second belt 202h; The pressing bump 203a fixed to the outer end surface of the connecting column 202j periodically contacts and pushes the pressed disc 203c as the connecting column rotates, causing the hinged rod 203b to swing around its hinge point. The swing of the hinged rod drives the slider 203d to slide along the inner wall of the limit guide 201d. At the same time, the pushing block 203e slides along the inner wall of the communication groove 201c driven by the slider. When the protruding part of the pressing bump 203a squeezes the pressed disc 203c, the hinged rod 203b drives the slider 203d and the pushing block 203e to move forward, pushing the plastic plate in the feeding frame 201b between the feeding roller 203f and the leveling roller 203g. At this time, the cooperation of the feeding roller 203f and the leveling roller 203g ensures that the plastic plate is leveled, reducing surface damage and smoothly conveying it to the guide plate 201e. The guide plate 201e guides the plastic plate to smoothly transition from the feeding frame above the fixed conveyor belt 102 and the movable conveyor belt 103. When the concave part of the pressing bump 203a rotates towards the direction close to the pressed disc 203c, the pressed disc loses pressure with the hinged rod, and the reaction force of the spring resets the pressed disc, hinged rod, slider, and pushing block synchronously, preparing for the next pushing action. In this way, the feeding assembly 203 realizes the accurate, stable, and continuous feeding of the plastic plate, ensuring that each plastic plate can be accurately conveyed to the surfaces of the fixed conveyor belt 102 and the movable conveyor belt 103; When it is necessary to adjust the position of the movable conveyor belt 103 to adapt to plastic plates of different widths: it is adjusted by rotating the handwheel 104e. The handwheel 104e drives the two threaded rods to rotate synchronously through the cooperation of the threaded rod 104a and the synchronous belt 104f, causing the internal threaded column 104b to drive the connecting block 104c and the movable conveyor belt 103 to move along the limit rod 104d, thereby adjusting the spacing between the movable conveyor belt and the fixed conveyor belt to ensure the accurate alignment of the plastic plate during transportation.

[0041] In summary, the adjusting assembly 104 can adjust the spacing between the movable conveyor belt 103 and the fixed conveyor belt 102 as needed to ensure the accurate alignment of the plastic plate during transportation. The feeding assembly 203 can intermittently send the stacked plastic plates above the movable conveyor belt 103 and the fixed conveyor belt 102, eliminating the problems of inaccurate placement positions and uneven placement frequencies caused by manually placing each plastic plate one by one, so as to achieve the effects of greatly improving the feeding speed, transportation efficiency, and transportation stability. Embodiment 2

[0042] Referring to Figures 1 to 8 , this is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that this embodiment provides a palletizing assembly 205 for cooperating with palletizing plates, and a lifting assembly 204 for providing power to the palletizing assembly 205.

[0043] It should be noted that the lifting component 204 includes a fixing plate 204a arranged on the side of the support platform 101 away from the first servo motor 202a, a second servo motor 204b adaptively installed outside the fixing plate 204a, a support column 204c fixedly installed at the output end of the second servo motor 204b through a coupling, a first sprocket 204d fixedly installed at the penetrating end of the support column 204c, a chain 204e sleeved on the outer surface of the first sprocket 204d, and a second sprocket 204f sleeved on the inner surface of the other end of the chain 204e.

[0044] Furthermore, the palletizing component 205 includes a fork plate 205a fixedly installed on the outer surface of the chain 204e through a bearing, a guiding sleeve plate 205b slidably sleeved on the outer surface of the fork plate 205a, positioning columns 205c respectively fixedly connected to the inner walls on both sides of the fixing plate 204a and used in cooperation with the guiding sleeve plate 205b, a first notched fork plate 205d fixedly connected to the surface of the fixing plate 204a close to the support platform 101, a limiting plate 205e fixedly connected to the end surface of the first notched fork plate 205d close to the fork plate 205a, a second notched fork plate 205f fixedly connected to the surface of the fixing plate 204a away from the first notched fork plate 205d, and a material receiving box 205g arranged directly below the second notched fork plate 205f.

[0045] Among them, the ends of both the first notched fork plate 205d and the second notched fork plate 205f are inclined towards the direction close to the material receiving box 205g, and the fork bars on the surfaces of the first notched fork plate 205d and the second notched fork plate 205f are arranged in a staggered manner with the fork bars on the surface of the fork plate 205a. Thus, while preventing the first notched fork plate 205d and the second notched fork plate 205f from blocking the movement track of the fork plate 205a, the fork plate 205a can lift the plastic plate on the surface of the first notched fork plate 205d and place it on the surface of the second notched fork plate 205f.

[0046] Furthermore, the bottom of the movable conveyor belt 103 is fixedly connected to the top of the connecting block 104c. The inner surface of the connecting block 104c is in sliding contact with the outer surface of the limiting rod 104d. The limiting guide rail 201d is located directly below the communication groove 201c, and the inner cavities of the communication groove 201c and the limiting guide rail 201d are communicated.

[0047] Specifically, the through end of the spline shaft 202b is fixedly installed on the inner wall of the support table 101 through a bearing. The outer surface of the spline shaft 202b is in sliding contact with the inner surfaces of the drive shafts of the fixed conveyor belt 102 and the movable conveyor belt 103. The first pulley 202c is located outside the support table 101. The outer end face of the connecting rod 202f penetrates to the inside of the material discharging frame 201b. A bearing sleeve for mating rotation is installed at the connection between the connecting column 202j and the fixed frame 201a. The outer surface of the pushing block 203e is in sliding contact with the inner wall of the limiting guide rail 201d. The outer surface of the pushing block 203e is in sliding contact with the inner wall of the pressure receiving disc 203c. The outer end face of the feeding roller 203f is fixedly installed on the inner wall of the material discharging frame 201b through a bearing.

[0048] Preferably, the second sprocket 204f is fixedly installed on the inner side wall of the fixing plate 204a through a bearing. The inner surface of the guiding sleeve plate 205b is in sliding contact with the outer surface of the positioning column 205c.

[0049] During use, the plastic plate falls from the ends of the movable conveyor belt 103 and the fixed conveyor belt 102 above the first notched fork plate 205d. The plastic plate slides along the inclined surface of the first notched fork plate 205d towards the direction close to the limiting plate 205e, and is finally intercepted by the limiting plate 205e to ensure the stability of its position before lifting. Subsequently, the second servo motor 204b is started to drive the support column 204c and the first sprocket 204d to rotate synchronously. The first sprocket 204d drives the second sprocket 204f to rotate through the chain 204e. Further, the chain 204e drives the fork plate 205a to move synchronously. The positioning column 205c limits the guiding sleeve plate 205b to ensure that the guiding sleeve plate 205b remains perpendicular during the movement of the fork plate 205a, preventing the angle of the fork plate from shifting, so as to ensure that the fork plate 205a always remains parallel to the first notched fork plate 205d and the second notched fork plate 205f. When the fork plate 205a moves upward from the bottom: it passes through the first notched fork plate 205d and smoothly lifts the plastic plate on its surface. The fork plate 205a rises synchronously along the movement track of the chain 204e to ensure the stability of the plastic plate during the entire lifting process. When the fork plate 205a continues to rise and passes through the second notched fork plate 205f, the surface of the second notched fork plate 205f intercepts the plastic plate on the fork plate. At this time, under the action of its own gravity, the plastic plate smoothly slides into the inside of the material receiving box 205g. The entire palletizing process is automatically cycled to ensure that each plastic plate can be accurately and stably stacked. After the fork plate 205a completes one palletizing operation, it will automatically reset and be ready for the next grasping and palletizing operation. This design not only improves the production efficiency, but also significantly improves the product quality and safety, reduces manual intervention, and lowers the operation cost.
