Description

TECHNICAL FIELD

[0001] The application relates to the technical field of gypsum board production, in particular to a gypsum board turnover device. BACKGROUND

[0002] Gypsum board is a very important and common decorative material. In a paper-faced gypsum board production line, a turnover machine for turning over gypsum board is an important device. The turnover machine is used for turning over the gypsum board to be dried. The paper-faced gypsum board has gypsum slurry as a core and at least one side is protected by paper. During processing, the paper on the lower layer is placed on a conveying belt, and the water moves downward, which results in more water on the lower surface. Therefore, the gypsum board needs to be turned over by 180 degrees by the turnover machine so that the paper on the lower layer is turned to the upper side, thereby facilitating drying.

[0003] The existing turnover machine is usually directly driven by a motor to drive a turnover frame or driven by a chain to drive a turnover frame to make a turnover movement. The turnover machine is only driven by a motor or a chain, and the stability is poor, which easily causes large vibration of the gypsum board, thereby causing the gypsum board to be cracked and affecting the product quality.

[0030] With reference to the drawings and the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work are within the protection scope of the present application. Figure 1The gypsum board overturning device provided by the embodiment of the present application comprises a feeding frame 1, an overturning frame 8 and an overturning motor 9. One end of the feeding frame 1 is provided with an inlet roller 2, the inlet roller 2 is driven to rotate synchronously by an inlet motor 5 in combination with synchronous pulley and synchronous belt, the other end of the feeding frame 1 is provided with an outlet roller 3, the outlet roller 3 is driven to rotate synchronously by an outlet motor 6 in combination with synchronous pulley and synchronous belt, and the upper side of the outlet roller 3 is provided with a stripping roller 4 at intervals, the stripping roller 4 is driven to rotate by a stripping motor 7. It should be noted that the height of the feeding roller in the horizontal direction is higher than the height of the outlet roller 3 in the horizontal direction, so that the gypsum board 17 can smoothly reach the outlet roller 3 after being overturned.

[0031] As shown in Figure 1 , the overturning frame 8 is located between the inlet roller 2 and the outlet roller 3, the overturning frame 8 is fixed to a shaft, the shaft is rotatably installed on the feeding frame 1, and the shaft is connected with the overturning motor 9 through a shaft coupling at one end, the overturning frame 8 is rotated by 180 degrees between the inlet roller 2 and the outlet roller 3 by the forward and reverse rotation of the overturning motor 9. At the same time, a support table for supporting the overturning frame 8 is arranged on the feeding frame 1 between the inlet roller 2 and the outlet roller 3 and closer to the inlet roller 2, and the end of the overturning frame 8 away from the shaft is supported on the support table in a natural state.

[0032] As shown in Figure 2 and Figure 3 , the overturning frame 8 is provided with a storage cavity 10, in a natural state, the storage cavity 10 is internally sunk from the side of the inlet roller 2 to the side of the outlet roller 3 without penetrating, and the cavity opening faces the side of the inlet roller 2, that is, when the gypsum board 17 is placed on the inlet roller 2, it enters the storage cavity 10 from the side of the inlet roller 2, and since the side of the outlet roller 3 of the storage cavity 10 is closed, the gypsum board 17 is in a state of being adhered to the storage cavity 10 after entering the storage cavity 10. Of course, in order to facilitate the gypsum board 17 to smoothly enter the storage cavity 10, the width of the cavity opening of the storage cavity 10 gradually decreases from outside to inside, and the minimum width of the cavity opening is the same as the width of the gypsum board 17, so that the larger cavity opening can make the gypsum board 17 more easily enter the storage cavity 10.

[0033] In addition, in order to accurately control the overturning time of the overturning frame 8, in a more preferred embodiment, as shown in Figure 2 and Figure 3 , a contact switch 18 is fixedly installed on the inner wall of the storage cavity 10 at the end of the outlet roller 3, when the gypsum board 17 enters the storage cavity 10 and contacts the contact switch 18, the control system controls the overturning motor 9 to overturn to the side of the outlet roller 3, and then completes the discharging, the time from overturning to completing discharging is determined, so after the preset time, the control system controls the overturning motor 9 to reverse to send the overturning frame 8 back to the side of the inlet roller 2.

[0034] Meanwhile, in order to enable the gypsum board 17 to be rotated 180 degrees and exit the storage cavity 10, a stripping slide plate 12 that is slidably connected to the flipping frame 8 is provided in the storage cavity 10. In its natural state, the stripping slide plate 12 faces upward. After being rotated, the stripping plate can be on the downward side and then slide out of the storage cavity 10 with the gypsum board 17.

[0035] Specifically, such as Figure 2 and Figure 3 As shown, in its natural state, the top surface of the tilting frame 8 is provided with a sliding cavity 11 for installing the stripping slide 12, and after the stripping slide 12 is installed in the sliding cavity 11, the stripping slide 12 is flush with the tilting frame 8. Along the length of the tilting frame 8, the sliding cavity 11 has an inner groove 14 and a side groove 13 on both sides. The inner groove 14 and the side groove 13 coincide on the same horizontal plane, and the inner groove 14 is deeper than the side groove 13 to form a blocking structure at the cavity opening. Guide sliders 16 are provided on both sides of the stripping slide 12, and a limiting slider 15 is provided on the side of the stripping slide 12 away from the cavity opening. The limiting slider 15 extends into the inner groove 14, while the guide slider 16 is slidably disposed within the side groove 13. When the stripping slide 12 slides outward, the limiting slider 15 prevents it from completely detaching from the tilting frame 8.

[0036] As can be imagined, the working process of the gypsum board flipping device provided in this application embodiment is as follows:

[0037] First, the gypsum board 17 is placed on the feed roller 2. The feed roller 2 drives the gypsum board 17 into the storage chamber 10. When the gypsum board 17 contacts the contact switch 18, the flipping motor 9 rotates, and the flipping frame 8 flips from one side of the feed roller 2 to the side of the discharge roller 3. During the flipping process, since the storage chamber 10 is closed on the side of the discharge roller 3, the gypsum board 17 can be well maintained in the storage chamber 10, and the stripping slide plate 12 will not slide, thus forming a good fit for the gypsum board 17, which can reduce the vibration amplitude of the gypsum board 17 during the flipping process and reduce the risk of cracking. When the tilting frame 8 is rotated 180 degrees, it stops at the discharge roller 3. The stripping slide 12 faces downward and contacts the discharge roller 3. As the discharge roller 3 rotates, it will drive the stripping slide 12 to slide out of the sliding cavity 11 to the maximum stroke, thereby driving the gypsum board 17 out of the storage cavity 10. The upper surface of the gypsum board 17 that has exited the storage cavity 10 contacts the stripping roller 4 located above. Under the action of the stripping roller 4, the stripping slide 12 slides down and onto the discharge roller 3, thus reaching the discharge roller 3 and being sent to the next stage of drying.

[0038] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
