Description

Technical Field

[0001] This utility model relates to the field of calcium silicate board stacking and processing, specifically to a three-station stacking machine for calcium silicate boards. Background Technology

[0002] Calcium silicate board is an inorganic board made from siliceous and calcareous materials as the base material, with added reinforcing fibers such as pulp fiber and glass fiber, along with other additives. It is produced through processes including slurry preparation, molding, and high-temperature, high-pressure steam curing. It possesses fireproof, moisture-proof, sound-insulating, and corrosion-resistant properties, and is widely used in building partitions and ceilings. During the production process, the pressed blanks need to be stacked before cutting and steam curing. This is typically achieved using a stacker crane to separate and stack the blanks from the template. The processed blanks are then sent to an autoclave for steam curing. Currently, calcium silicate board production lines use stackers that operate with single or double boards, placed on a lifting platform. Simply increasing the output speed and power of the production geared motor to extend the stacker crane's production cycle is difficult and costly. Therefore, it is necessary to design a new type of stacker crane for board production to shorten the production cycle and improve efficiency. Utility Model Content

[0003] To address the aforementioned problems, the main objective of this invention is to provide a three-station stacker for calcium silicate boards, which enables automated control, ensures neat stacking, and significantly improves production efficiency.

[0004] To achieve the above objectives, the present invention provides a three-station stacker for calcium silicate boards, comprising a fixed frame, a servo transmission system, a servo lifting system, a blank suction cup device, and a template suction cup device. The fixed frame includes an operating platform and a support frame, with the support frame located on the lower end face of the operating platform. The servo transmission system includes a first servo motor reducer, a rotating shaft, a synchronous belt, a synchronous pulley, and a traveling frame. The servo lifting system includes two lifting drive units, each comprising a lifting arm, a drive gear, a lifting rack, and a second servo motor reducer. The template suction cup device includes a vacuum suction cup and a negative pressure device.

[0005] Furthermore, the first servo motor reducer is fixed to the edge of the upper surface of the operating platform, and the first servo motor reducer drives the rotating shaft to rotate. The rotating shaft is rotatably fixed to the edge of the upper surface of the operating platform through several mounting brackets.

[0006] Furthermore, there are four synchronous pulleys, which are fixedly mounted on the outer peripheral walls at both ends of the rotating shaft. There are two synchronous belts, which are respectively fitted onto two synchronous pulleys on the same side of different rotating shafts.

[0007] Furthermore, the two ends of the synchronous belt are fixedly connected to the two ends of the traveling frame, the servo lifting system is fixed on the traveling frame, and several rollers are provided on the front and rear sides of the traveling frame, with the rollers abutting against the upper surface of the operating platform.

[0008] Furthermore, the lower end of the lifting arm is provided with a plate picking and placing mechanism. The plate picking and placing mechanism at the bottom of the lifting arm of any one lifting drive unit is connected to the blank suction cup device, and the plate picking and placing mechanism at the bottom of the lifting arm of another lifting drive unit is connected to the template suction cup device.

[0009] Furthermore, the drive gear is mounted on the walking frame and meshes with the lifting rack, and the second servo motor reducer is used to drive the rotation of the drive gear.

[0010] Furthermore, the lifting rack is fixed vertically to the outer wall of the lifting arm.

[0011] Through the above technical solution, the three-station stacker for calcium silicate boards of this utility model uses a gear and rack transmission of a servo lifting system to pick up and place blanks or templates during use.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Please see Figures 1 to 8 The three-station stacker for calcium silicate boards provided by this utility model includes a fixed frame 1, a servo transmission system 2, a servo lifting system 3, a billet suction cup device 4, and a template suction cup device 5, wherein, as shown... Figure 1 As shown, the fixed frame 1 is equipped with an operating platform 11 and a support frame 12. The upper end of the support frame 12 is fixed to the lower end face of the operating platform 11, and the lower end of the support frame 12 is located on a horizontal plane. Figure 1 and Figure 3As shown, the servo transmission system 2 of this utility model includes a first servo motor reducer 21, a rotating shaft 26, a synchronous belt 22, synchronous pulleys 23, and a traveling frame 24. The first servo motor reducer 21 is fixed to the edge of the upper surface of the operating platform 11. The first servo motor reducer 21 drives the rotating shaft 26 to rotate. The rotating shaft 26 is rotatably fixed to the edge of the upper surface of the operating platform 11 by a number of mounting brackets 25. In this embodiment, there are eight mounting brackets 25, four of which are located at the two ends of the two rotating shafts 26. In addition, there are four synchronous pulleys 23, which are fixedly installed on the outer peripheral walls at both ends of the rotating shaft 26 and located inside the mounting brackets 25 at both ends of the rotating shaft 26. There are two synchronous belts 22, which are respectively sleeved on two synchronous pulleys 23 on the same side of different rotating shafts 26.

[0030] Please continue reading. Figure 1 , Figure 3 and Figure 4 As shown, the two ends of the synchronous belt 22 of this utility model are fixedly connected to the two ends of the traveling frame 24, or in other embodiments, the two ends of the synchronous belt 22 are connected to the four corners of the traveling frame 24, which can be the upper corner or the lower corner. In addition, the front and rear sides of the traveling frame 24 are provided with a plurality of rollers 241, and the rollers 241 abut against the upper surface of the operating platform 11.

[0031] The working principle of the servo transmission system of this utility model is as follows: When the first servo motor reducer 21 is started, it drives the rotating shaft 26 to rotate, which in turn drives the synchronous pulley 23 to rotate. The synchronous belt 22 sleeved on the outer circumference of the synchronous pulley 23 also begins to rotate. Since the two ends of the traveling frame 24 and the synchronous belt 22 are fixedly connected, the traveling frame 24 will move in position during the rotation of the synchronous belt 22. The direction of movement is perpendicular to the setting direction of the rotating shaft 26. In addition, since multiple rollers 241 are provided on the side of the traveling frame 24, the rollers 241 are more conducive to making the movement of the traveling frame 24 smooth and stable.

[0032] Please see Figure 1 and Figure 4As shown, the servo lifting system 3 of this utility model is fixed on the traveling frame 24. The servo lifting system 3 is provided with two lifting drive units. Each lifting drive unit includes a lifting arm 34, a drive gear 32, a lifting rack 31, and a second servo motor reducer 33. The drive gear 32 is mounted on the traveling frame 24, and the drive gear 23 meshes with the lifting rack 31. The lifting rack 31 is fixed vertically to the outer wall of the lifting arm 34. The second servo motor reducer 33 can drive the drive gear 32 to rotate. Therefore, after the second servo motor reducer 33 is started, as the second servo motor reducer 33 drives the drive gear 32 to rotate, the height of the lifting rack 31 can change, thereby realizing the upward or downward displacement of the lifting arm 34. It should be noted that... The operating platform 11 of this utility model has a first notch in the middle (not shown in the figure), and the traveling frame 24 has a second notch in the middle (not shown in the figure). The area of ​​the first notch is larger than the area of ​​the second notch. The lifting arm 34 is located in the first and second notches. There is also a slide rail structure between the lifting arm 34 and the traveling frame 24. For example, a slide rail is set on the inner wall of the second notch of the traveling frame 24, and a slider is set on the outer periphery of the lifting arm 34. The slider cooperates with the slide rail. Thus, during the adjustment of the lifting arm 34 by the second servo motor reducer 33, the lifting arm 34 is not only connected by the lifting rack 31 and the drive gear 32, but also has other supporting components, so as to ensure that the lifting arm 34 can achieve stable up and down movement.

[0033] In addition, the lower end of the lifting arm 34 of this utility model is provided with a plate picking and placing mechanism 6. The plate picking and placing mechanism 6 at the bottom of the lifting arm 34 of any one lifting drive unit is connected to the blank suction cup device 4, and the plate picking and placing mechanism 6 at the bottom of the lifting arm 34 of another lifting drive unit is connected to the template suction cup device 5. The template suction cup device 5 is provided with a vacuum suction cup 51 and a negative pressure device 52. Therefore, as the lifting arm 34 moves up and down, the plate picking and placing mechanism 6 also moves at the same time, thereby realizing the plate picking and placing operation of the blank or template by the blank suction cup device 4 and the template suction cup device 5.

[0034] In the operation of this stacker, two steam curing trolleys filled with a mixed stack are first pushed side by side into the mixed stack station. Two empty steam curing trolleys 7 are then pushed into the blank stack station. The blank slab suction cup device 4 and the template suction cup device 5 are positioned above the mixed stack station. The blank slab suction cup device 4 and the template suction cup device 5 lift two blanks upwards. The traveling frame 24 moves towards the blank stack station, and the blank slab suction cup device 4 and the template suction cup device 5 descend onto the template trolley, completing the suction and release of the template and blank. Afterwards, the servo drive system reverses, and the traveling frame 24 returns to the starting station, thus realizing reciprocating transport. Using this three-station stacker for calcium silicate boards, the length of the suction cups is doubled, while the lifting platform equipment in existing technologies is eliminated, saving stack replacement time and significantly improving production capacity.

[0035] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
