Manually installing and removing the caps, as well as loading and unloading the racks, is not only inefficient, but also increases labor and space costs due to the need for storage and transfer of the removed caps. Therefore, an automated loading and unloading production line for SCR cement catalyst is needed. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Next, refer to Figures 1 to 2 The working principle of this embodiment will be described in detail so that those skilled in the art can better understand this utility model: An automated loading and unloading production line for SCR cement catalysts includes a multi-layer fixed frame 1 and placement trays. The placement trays hold multiple SCR cement catalysts, typically arranged in an array. A lid is then used to cover the SCR cement catalysts to prevent dust accumulation and adsorption on the surface during the drying and hardening process. The multi-layer fixed frame 1 loads the placement trays, thus fully utilizing the longitudinal space for drying large quantities of SCR cement catalysts.

[0020] The automated loading and unloading production line for SCR cement catalysts also includes a loading production line, an unloading production line, and a capping and unloading device.

[0021] The feeding production line includes a first conveyor belt 2, a first lifting device 3, and a first transfer device 4. The first lifting device 3 is located at one end of the first conveyor belt 2, and the other end of the first conveyor belt 2 is connected to an extruder. The extruder is used to produce SCR cement catalyst, and the first conveyor belt 2 is used to transport the placement trays from the extruder to the end of the first conveyor belt. The first transfer device 4 is installed on the first lifting device 3. The first transfer device 4, in conjunction with the first lifting device 3, can lift the placement trays and then transfer the placement trays on the first conveyor belt 2 to the multi-layer fixed frame 1. Furthermore, the first transfer device 4, in conjunction with the first lifting device 3, can transfer the placement trays to each layer of the multi-layer fixed frame 1.

[0022] The feeding production line includes a second conveyor belt 5, a second lifting device 6, and a second transfer device 7. The second lifting device 6 is located at one end of the second conveyor belt 5, and the other end of the second conveyor belt 5 is connected to a palletizer. The second conveyor belt 5 is used to transport placement trays, moving the trays on the multi-layer fixed frame 1 to the palletizer. Before palletizing, the lids on the placement trays need to be removed to avoid interference with the palletizer. The transport direction of the second conveyor belt 5 is opposite to that of the first conveyor belt 2, and the first conveyor belt 2 and the second conveyor belt 5 are arranged parallel to each other. The second transfer device 7 is installed on the second lifting device 6 and is used to transfer the placement trays on the multi-layer fixed frame 1 to the second conveyor belt 5. The working principles of the second lifting device 6 and the second transfer device 7 are the same as those of the first lifting device and the first transfer device, respectively.

[0023] The lid-closing and unloading device is located at one end of the first conveyor belt 2 near the lifting device. Before the first conveyor belt 2 transports the placement tray from the extruder to the other end awaiting transfer by the first transfer device 4, the first conveyor belt 2 stops. At this time, the second transfer device 7 transfers the placement tray from the corresponding multi-layer fixed frame 1 to one end of the second conveyor belt 5. The second conveyor belt 5 also remains stationary, waiting for the lid-closing and unloading device to move the lids from the unloading production line's placement tray to the loading production line's placement tray. Only after the lid-closing and unloading device completes the transfer of the lids will the first transfer device 4 and the second conveyor belt 5 start. If the working hours of the loading and unloading production lines cannot be matched, a placement tray storage rack can be placed next to the first conveyor belt 2 for temporary storage and transfer.

[0024] The multi-layer fixed frame 1 is automatically loaded and unloaded by the feeding production line and the unloading production line. The lid is automatically moved from the placement tray on the unloading production line to the placement tray on the feeding production line by the lid loading and unloading device. There is no need for storage and placement in the area for transfer. It completely replaces manual production activities, thereby improving production efficiency and saving space costs.

[0025] The first lifting device 3 and the second lifting device 6 have the same structure. The first lifting device 3 includes a support frame 31, guide rods 32, lead screws 33, a lifting platform 34, and a first motor 35. Four guide rods 32 are vertically installed inside the support frame 31. Guide holes corresponding to the guide rods 32 are opened at the corners of the lifting platform 34. Each guide hole is slidably connected to a guide rod 32. The guide rods 32 are used to increase the stability of the lifting platform 34 when it moves up and down. Since the middle area of ​​the lifting platform 34 needs to allow the transfer device and the placement tray to pass through, guide holes can only be set at the edges. Threaded holes are opened on both sides of the lifting platform 34. Two lead screws 33 are vertically installed inside the support frame 31 through bearings. The lead screws 33 are symmetrically arranged about the center line of the symmetrical platform. The center line is parallel to the direction of movement of the slide plate 44. The lead screws 33 are threadedly connected to the threaded holes. The first motor 35 is installed on the top of the support frame 31, and the motor output end is connected to the top of the lead screw 33. When the first motor 35 starts, it drives the lead screw 33 to rotate. Since the lifting platform 34 cannot rotate under the action of the guide rod 32, it moves along the direction of the lead screw 33 with the cooperation of the lead screw 33 and the threaded hole, thus performing lifting motion. The distance between the lead screw 33 and the guide rod 32 on the same side parallel to the direction of movement of the slide plate 44 is equal, ensuring that the lifting platform 34 is subjected to uniform force and avoiding jamming. The height of the multi-layer fixing frame 1 is less than the length of the lead screw 33.

[0026] In another embodiment, a hydraulic cylinder or a pneumatic cylinder can be used instead of the lead screw 33 to drive the vertical movement of the lifting platform 34. This method results in faster movement and can also achieve precise control. However, compared to using the lead screw 33, pneumatic and hydraulic cylinders require more space to house them, and also require the installation of pumps and the arrangement of pipelines, resulting in higher equipment costs. The choice can be made based on the actual situation.

[0027] The first transfer device 4 and the second transfer device 7 have the same structure. The first transfer device 4 includes a second motor 41, a drive shaft 42, a linear transmission mechanism, a base 43, a slide plate 44, and a support plate. The lifting platform 34 is annular, so the middle area is a through hole. Two bases 43 are symmetrically installed on the lifting platform 34 about its center line, and the distance between the bases 43 is smaller than the interval in the middle of the conveyor belt. The linear transmission mechanism is installed inside the base 43, and the slide plate 44 is slidably installed on the top of the base 43. The moving direction of the slide plate 44 is the same as the transmission direction of the first conveyor belt 2. The slide plate 44 is connected to one end of the linear transmission mechanism, and the other ends of the two linear transmission mechanisms are respectively connected to both ends of the drive shaft 42. The support plate is installed at the midpoint of the bottom of the base 43, and the second motor 41 is installed on the support plate. The output end of the second motor 41 is connected to one end of the drive shaft 42. When the second motor 41 starts, it drives the drive shaft 42 to rotate, and the drive shaft 42 drives the linear transmission mechanism to drive the slide plate 44 to move linearly. The linear transmission mechanism here is a gear rack or lead screw slider, etc., and the gear or lead screw is connected to the transmission shaft 42.

[0028] When it is necessary to move the placement tray on the first conveyor belt 2 to the multi-layer fixed frame 1, the slide plate 44 moves to below the placement tray under the drive of the linear transmission mechanism. Then, the lifting platform 34 rises, and the slide plate 44 abuts against the bottom of the placement tray, causing the placement tray to separate from the first conveyor belt 2 to a set distance. Afterwards, the slide plate 44 moves the placement tray into the support frame 31 to avoid interference with other items when the placement tray moves up and down. The first motor 35 starts according to the program execution sequence, moves the placement tray to a layer with an empty space in the multi-layer fixed frame 1, the slide plate 44 moves the placement tray into the multi-layer fixed frame 1, the lifting platform 34 moves down, the placement tray falls on the multi-layer fixed frame 1, and the slide plate 44 separates from the placement tray. When it is necessary to move the placement tray of the multi-layer fixed frame 1 to the second conveyor belt 5, the operation process of the equipment is the reverse of the above, and will not be described in detail here. After the multi-layer fixed frame 1 has completed loading or unloading, the operator uses a forklift to transfer the multi-layer fixed frame 1.

[0029] Anti-slip pads are installed on the slide plate 44 to increase friction with the placement tray and ensure the stability of the placement tray when the slide plate 44 moves. The spacing between the slide plates 44 is two-thirds to three-quarters of the width of the placement tray, which ensures the stability of the placement tray while avoiding the first conveyor belt 2, the second conveyor belt 5 and the multi-layer fixing frame 1.

[0030] The lid-closing and unloading device 8 includes a truss 81, a horizontal shaft assembly 82, a vertical shaft assembly 83, and a negative pressure adsorption assembly 84. The truss 81 is placed at one end of the first conveyor belt 2 near the first lifting device 3 and connected to the ground via anchor bolts. The projection of the truss 81 on the horizontal plane is perpendicular to the first conveyor belt 2, and the projection of the truss 81 on the horizontal plane completely covers the first conveyor belt 2 and the second conveyor belt 5. The horizontal shaft assembly 82 is horizontally mounted on the truss 81, the vertical shaft assembly 83 is vertically mounted on the horizontal shaft assembly 82, and the negative pressure adsorption assembly 84 is mounted at the bottom of the vertical shaft assembly 83. The negative pressure adsorption assembly 84 is connected to a vacuum pump via a pipe. The horizontal shaft assembly 82 drives the vertical shaft assembly 83 and the negative pressure adsorption assembly 84 to move horizontally, the vertical shaft assembly 83 drives the negative pressure adsorption assembly 84 to move vertically, and the negative pressure adsorption assembly 84 is used to grip and close the lid. The negative pressure adsorption assembly 84 mainly consists of three parts: a suction cup, a vacuum pump, and a control and detection unit. The suction cup, acting as the end effector, directly contacts the workpiece and forms a sealed space; the vacuum pump is responsible for removing air and creating a negative pressure environment; while components such as the solenoid valve and vacuum sensor are responsible for controlling the on / off state, adjusting the vacuum level, and monitoring the adsorption status in real time to ensure the reliability of the gripping. The aforementioned horizontal axis assembly 82 and vertical axis assembly 83 are either lead screw and slider mechanisms or gear and rack mechanisms, etc.

[0031] When the lid-closing and unloading device 8 needs to transfer the lid, the horizontal shaft assembly 82 moves the negative pressure adsorption assembly 84 to a position directly above the lid on the second conveyor belt 5. Then, the vertical shaft assembly 83 moves the negative pressure adsorption assembly 84 down to contact the top of the lid, the vacuum pump starts, and the negative pressure adsorption assembly 84 grips and fixes the lid. Then, the vertical shaft assembly 83 moves the negative pressure adsorption assembly 84 and the lid upward, the horizontal shaft assembly 82 moves the negative pressure adsorption assembly 84 and the lid to a position directly above the placement tray on the first conveyor belt 2, and the vertical shaft assembly 83 moves the negative pressure adsorption assembly 84 and the lid downward until the lid covers the placement tray. The vacuum pump stops, and the vertical shaft assembly 83 moves the negative pressure adsorption assembly 84 upward, separating it from the lid.

[0032] A positioning frame 9 is installed on the side of the support frame 31 away from the lid-closing and unloading device. The positioning frame 9 includes a fixed base 91, connecting rods, and a side plate 92. One end of the fixed base 91 is bolted to the support frame 31, and the multi-layer fixed frame 1 is placed on the fixed base 91. The fixed bases 91 are symmetrically arranged on the side of the support frame 31 away from the lid-closing and unloading device. Both ends of the connecting rods are connected to the fixed bases 91 respectively, and multiple connecting rods are linearly arrayed between two fixed bases 91. The connecting rods are used to increase the stability of the fixed bases 91. A side plate 92 is installed on the side of the fixed bases 91 that is far apart from each other. The side plate 92 is used to limit the horizontal movement of the multi-layer fixed frame 1 to ensure that the placement tray can be stably placed on the multi-layer fixed frame 1.

[0033] A guide plate 93 is installed on the side plate 92. The guide plate 93 is in the shape of a zigzag line, which is used to increase the size of the opening interval between the side plates 92, making it easier for the operator to place the multi-layer fixing frame 1 on the fixing seat 91.
