When using conveyor belt to transport products or materials, in order to ensure that the conveying thickness of the products on the conveyor belt is always consistent, a scraper correction device is usually installed in the conveying device. The distance between the scraper correction device and the conveyor belt is set according to actual needs to achieve the purpose of controlling the thickness of the conveyed products on the conveyor belt to be consistent.

[0003] However, conveyor belt conveying belongs to circular conveying driven by a driving device, that is, the conveyor belt must have a joint in the production process to produce the conveyor belt into a ring shape, and the thickness of this joint part is not equal to the thickness of the non-joint part of the conveyor belt, and the thickness of the joint part is greater than the thickness of the non-joint part. Therefore, due to the setting of the scraper correction device, when the joint part passes through the scraper correction device, the thickness of the product left on the joint part is less than the thickness of the product on the non-joint part, thereby affecting the subsequent process.

[0031] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments are briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention, and for ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments cannot be described one by one here, but the embodiments of the present invention are not therefore limited to the following embodiments.

[0033] Combination Figure 1-Figure 8 As shown, the present invention provides an adjustable correction device for a conveying device, comprising a bottom frame 1, an action shaft 2 mounted on the bottom frame 1, a roller shaft 3 mounted on the action shaft 2, and a conveyor belt 4 mounted on the roller shaft 3. In this embodiment, a base 11 is provided on the bottom frame 1, and both ends of the action shaft 2 are mounted on the base 11. In this embodiment, two action shafts 2 are provided, which are arranged on both sides of the length direction of the conveyor belt 4. According to the concept of the present invention, one of the action shafts 2 is connected to a driving device such as a motor, and the motor drives the action shaft 2 to rotate when it works, thereby realizing the rotation of the conveyor belt 4.

[0034] The adjustable correction device for the conveying device of the present invention has baffle structures 5 symmetrically arranged on both sides of the conveyor belt 4, and the baffle structure 5 includes a mounting member 51 and a baffle 52 elastically connected to the mounting member 51. Specifically, the mounting member 51 includes a vertical portion 511 and a horizontal portion 512 connected to the vertical portion 511, and the vertical portion 511 is provided with a threaded hole and fixedly mounted on the bottom frame 1 by screws. The horizontal portion 512 is provided with a mounting hole 513, and a spring 514 is fixedly connected in the mounting hole 513. The baffle 52 has a through hole 521 for the action shaft 2 to pass through, and the baffle 52 is also provided with a guide column 522, which extends into the mounting hole 513 and is fixedly connected to the spring 514.

[0035] The adjustable correction device for the conveying device of the present invention can stretch the spring 514 when the baffle 52 is subjected to an inward force, and can further approach the conveyor belt 4 from both sides of the conveyor belt 4, thereby improving the problem of products on the conveyor belt 4 falling from both sides of the conveyor belt 4 without affecting the normal operation of the conveyor belt 4.

[0036] The adjustable correction device for the conveying device of the present invention is further provided with a scraper correction structure 8 on the bottom frame 1, and the scraper correction structure 8 includes two pillars 81 fixedly mounted on the bottom frame 1 and symmetrically arranged, a connecting member 82 elastically connected to the pillars 81, and a scraper 83 connected to the connecting member 82. The pillars 81 are fixed to the bottom frame 1 by bolts, and the pillars 81 are provided with a vertical mounting hole 811. A third spring 812 is fixedly mounted in the vertical mounting hole 811, and the connecting member 82 is provided with a second guide column 821 extending into the vertical mounting hole 811 and fixedly connected to the third spring 812. The scraper 83 is detachably connected to the connecting member 82 by screws.

[0037] In the adjustable correction device for the conveying device of the present invention, a transmission wheel 6 is also installed on the action shaft 2, and a transmission belt 7 is installed on the transmission wheel 6. The transmission wheel 6 is located outside the baffle structure 5. Specifically, the transmission wheel 6 is located outside the baffle 52 and contacts the baffle 52. The transmission wheel 6 is provided with a plurality of oblique holes 61 at equal intervals along its circumference. In this embodiment, the number of oblique holes 61 is three. A second spring 62 is provided in the oblique hole 61. One end of the second spring 62 is fixedly connected to the oblique hole 61, and the other end is connected to a pressure block 63. The pressure block 63 is located in the oblique hole 61, and the outer surface of the pressure block 63 is flush with the outer surface of the transmission wheel 6.

[0038] In this embodiment, the transmission belt 7 and the conveyor belt 4 have the same joint part, and after the transmission belt 7 is installed, the position of the joint part is the same as the position of the joint part on the conveyor belt 4. When the action shaft 2 rotates, the roller shaft 3 and the transmission wheel 6 are synchronously driven to rotate, thereby realizing the synchronous rotation of the transmission belt 7 and the conveyor belt 4, and then the joint part on the conveyor belt 7 and the joint part on the conveyor belt 4 always rotate forward synchronously. In actual production, the transmission belt 7 and the conveyor belt 4 can be produced from a connected conveyor belt, that is, a connected conveyor belt is divided into a conveyor belt 4 and two belts 7.

[0039] In the present invention, an auxiliary rotating wheel 523 is provided on the baffle 52, and the auxiliary rotating wheel 523 is located below the connecting member 82. The transmission belt 7 is located between the connecting member 82 and the auxiliary rotating wheel 523 and contacts the connecting member 82 and the auxiliary rotating wheel 523 respectively.

[0040] The working principle of the present invention is as follows:

[0041] When the action shaft 2 rotates under the drive of the driving device, the conveyor belt 4 and the transmission belt 7 are driven to rotate synchronously. Since the transmission belt 7 is arranged between the connecting member 82 and the auxiliary rotating wheel 523, when the joint part of the transmission belt 7 rotates to the bottom of the connecting member 82, the joint part gradually becomes thicker, and the connecting member 82 is lifted up, thereby driving the scraper 83 to move upward. At this time, the joint part of the conveyor belt 4 moves to the bottom of the scraper 83. When the transmission belt 7 continues to move forward, after the joint part passes through the connecting member 82, the connecting member 82 is reset under the action of the third spring 812, thereby realizing the reset of the scraper 83. The setting of the auxiliary rotating wheel 523 is conducive to ensuring that the transmission belt 7 is deformed downward when passing through the connecting member 82, ensuring the adjustment and correction accuracy of the scraper 83, and thus facilitating the consistent thickness of the products on the conveyor belt 4.

[0042] The adjustable correction device for the conveying device of the present invention, through the above-mentioned structural setting, since the transmission belt 7 and the conveyor belt 4 run synchronously and have the same structure, any thickness change at the joint will be directly transmitted to the scraper 83, so that the scraper 83 can respond and adjust the position in real time to ensure the consistency of product thickness. Because the thickness of the joint part of the conveyor belt usually changes gradually, compared with the form of using sensor detection and the action device to lift the slide plate, the implementation method of the present invention does not rely on high-precision control systems and complex sensor arrangements, and the adjustment and correction are more accurate.

[0043] In addition, when the action shaft 2 rotates, due to the above-mentioned settings of the transmission wheel 6 and the baffle assembly 5, the transmission wheel 6 rotates synchronously with the action shaft 2. Under the action of centrifugal force, the pressure block 5 moves outward, thereby generating a driving force for the baffle 52 to move, thereby helping to strengthen the contact between the baffle 52 and the conveyor belt 4, thereby helping to reduce the product from falling between the conveyor belt 4 and the baffle 52 without affecting the conveying of the conveyor belt 4.

[0044] The above is only one embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
