Description

Technical Field

[0001] This utility model relates to the field of anti-tipping technology for conveyor lines, specifically an anti-tipping limiting device for a filling machine conveyor line. Background Technology

[0002] A filling and conveying line is an automated production line primarily used to efficiently and accurately fill liquids, pastes, or granular materials into containers, and to complete subsequent processes such as conveying, sealing, and labeling. The system typically consists of modules such as a conveyor belt, filling machine, capping machine, and labeling machine, and is controlled by a PLC or industrial computer to ensure high-precision filling and stable transmission.

[0003] In the prior art, the authorized announcement number CN222433406U discloses a filling finished product partitioning conveying device, including an electric slide table, a conveying device, a U-shaped frame, a movable seat and a rotating mechanism. The U-shaped frame is fixedly installed at the bottom of the conveying device; the movable seat is located below the U-shaped frame and is installed on the slide table base of the electric slide table.

[0004] When using roller conveyors to transport packaging drums, the lack of necessary limiting devices on both sides of the conveyor causes the drums to easily shift laterally during transport, and in severe cases, even tip over. This is particularly noticeable with lightweight empty packaging drums, thus affecting the smooth progress of the entire transport process and potentially causing safety accidents. Therefore, an anti-tipping limiting device for filling machine conveyor lines is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-tipping limiting device for a filling machine conveyor line to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-tipping limiting device for a filling machine conveyor line, comprising a support leg, a conveyor frame fixedly mounted on the support leg, a conveyor roller rotatably mounted inside the conveyor frame, a packaging barrel placed above the conveyor roller, and limiting mechanisms installed on both sides of the conveyor frame. The limiting mechanism includes positioning sleeves fixedly mounted on both sides of the conveyor frame, a sliding rod slidably mounted inside the positioning sleeves, a left limiting frame fixedly mounted at the end of the sliding rod on one side of the conveyor frame, and a right limiting frame fixedly mounted at the end of the sliding rod on the other side of the conveyor frame. An adjustment mechanism is connected to the sliding rod.

[0007] Preferably, both the left and right limiting frames are provided with movable holes, a movable shaft is rotatably installed in the movable holes, and a guide wheel is rotatably installed on the movable shaft.

[0008] Preferably, a bearing is installed in the movable hole, and the movable shaft is rotatably installed in the movable hole via the bearing.

[0009] Preferably, the sliding rod is slidably installed on both sides of the conveying frame via a positioning sleeve, and the guide wheel is rotatably installed on the left and right limit frames via a movable shaft.

[0010] Preferably, the adjusting mechanism includes a mounting base fixedly installed at the bottom of the conveyor frame. A left L-shaped frame and a right L-shaped frame are slidably installed on both sides of the mounting base. Both the left and right L-shaped frames are provided with toothed grooves. A gear is rotatably installed in the middle of the mounting base. A drive shaft is fixedly installed on the gear. A worm gear is fixedly installed at the end of the drive shaft. A worm is rotatably installed below the worm gear and meshes with the worm gear. A handwheel is connected to the worm.

[0011] Preferably, a bearing is mounted on the mounting base, and the drive shaft is rotatably mounted on the mounting base via the bearing.

[0012] Preferably, the gear is rotatably mounted in the mounting base via a drive shaft, and the gear meshes with the tooth grooves on the left L-shaped frame and the right L-shaped frame respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this application, when the packaging barrel moves forward, the sliding rod can be pushed forward so that the edges of the left and right limiting frames abut against the sides of the packaging barrel, thereby limiting the packaging barrel from both sides and preventing it from tipping over. When the packaging barrel moves along the edges of the left and right limiting frames, the guide wheel will rotate, thereby reducing the friction between the limiting frames and the packaging barrel and reducing the risk of wear and tear on the packaging barrel.

[0015] 2. In this application, the worm gear's rotational transmission can be achieved by operating the handwheel. The rotation of the worm gear drives the worm wheel, which in turn causes the drive shaft to rotate. The rotation of the drive shaft drives the gear to rotate, and the gear's movement causes the left and right L-shaped frames to extend and retract. During the extension and retraction of the left and right L-shaped frames, the sliding rod will move back and forth to adjust the distance between the left and right limiting frames, thereby adapting to the positioning requirements of packaging barrels of different sizes.

[0021] 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.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for an anti-tipping limiting device for a filling machine conveyor line, including a support leg 1, a conveyor frame 2 fixedly installed on the support leg 1, a conveyor roller 3 rotatably installed inside the conveyor frame 2, a packaging barrel 4 placed above the conveyor roller 3, limiting mechanisms 5 installed on both sides of the conveyor frame 2, and an adjustment mechanism 6 connected to a sliding rod 502. Through the cooperation of the limiting mechanism 5 and the adjustment mechanism 6, the distance between the left limiting frame 503 and the right limiting frame 507 can be adjusted according to the size of the packaging barrel 4, so as to limit the packaging barrel 4 of different sizes.

[0023] like Figure 2 and Figure 3 As shown, the limiting mechanism 5 includes positioning sleeves 501 fixedly installed on both sides of the conveyor frame 2. A sliding rod 502 is slidably installed inside the positioning sleeves 501. A left limiting frame 503 is fixedly installed at the end of the sliding rod 502 on one side of the conveyor frame 2, and a right limiting frame 507 is fixedly installed at the end of the sliding rod 502 on the other side of the conveyor frame 2. Both the left limiting frame 503 and the right limiting frame 507 have movable holes 504. A movable shaft 506 is rotatably installed inside the movable hole 504. A guide wheel 505 is rotatably installed on the movable shaft 506. A bearing is installed inside the movable hole 504. The movable shaft 506 is rotatably installed inside the movable hole 504 through the bearing. The sliding rod 502 is slidably installed on both sides of the conveyor frame 2 through the positioning sleeves 501.

[0024] Specifically, when the packaging drum 4 begins to move forward, the sliding rod 502 can be pushed forward. During this process, the edges of the left limiting frame 503 and the right limiting frame 507 will closely abut against the two side surfaces of the packaging drum 4. In this way, the left limiting frame 503 and the right limiting frame 507 can provide stable limiting support for the packaging drum 4 from both sides, effectively preventing the packaging drum 4 from tipping over or shifting during movement. In addition, as the packaging drum 4 continues to move forward along the edges of the left limiting frame 503 and the right limiting frame 507, the guide wheel 505 mounted on the limiting frame will rotate accordingly. The rotation of the guide wheel 505 can significantly reduce the friction between the limiting frame and the contact surface of the packaging drum 4, thereby effectively reducing the risk of wear caused by friction during the movement of the packaging drum 4.

[0025] like Figure 2 and Figure 4 As shown, the adjustment mechanism 6 includes a mounting base 603 fixedly installed at the bottom of the conveyor frame 2. A left L-shaped frame 601 and a right L-shaped frame 602 are slidably installed on both sides of the mounting base 603, respectively. Both the left L-shaped frame 601 and the right L-shaped frame 602 are provided with toothed grooves 604. A gear 605 is rotatably installed in the middle of the mounting base 603. A drive shaft 606 is fixedly installed on the gear 605. A worm gear 607 is fixedly installed at the end of the drive shaft 606. A worm 608 is rotatably installed below the worm gear 607 and meshes with the worm gear 607. A handwheel 609 is connected to the worm 608. A bearing is installed on the mounting base 603, and the drive shaft 606 is rotatably installed on the mounting base 603 through the bearing.

[0026] Specifically, when the operator turns the handwheel 609, the rotation of the handwheel 609 causes the worm gear 608 to rotate. The rotation of the worm gear 608 further drives the worm wheel 607 to rotate. The rotation of the worm wheel 607 drives the drive shaft 606 to rotate. The rotation of the drive shaft 606 causes the gear 605 to rotate. The rotation of the gear 605 ultimately drives the left L-shaped frame 601 and the right L-shaped frame 602 to unfold or close. During the unfolding or closing of the left L-shaped frame 601 and the right L-shaped frame 602, these two L-shaped frames drive the sliding rod 502 to move back and forth. The back and forth movement of the sliding rod 502 further acts on the left limit frame 503 and the right limit frame 507, so that the distance between these two limit frames can be adjusted according to the actual size of the packaging barrel 4. Through this adjustment mechanism, the equipment can flexibly adapt to packaging barrels 4 of different sizes, ensuring that the left limit frame 503 and the right limit frame 507 can effectively limit the packaging barrel 4, thereby ensuring the stability and accuracy of the packaging process.

[0027] Working principle: The packaging drum 4 can be conveyed forward by the rotation of the conveyor roller 3. When the packaging drum 4 moves forward, it can push the sliding rod 502 forward, so that the edges of the left limit frame 503 and the right limit frame 507 abut against the two sides of the packaging drum 4, limiting the packaging drum 4 from both sides and preventing the packaging drum 4 from tipping over. When the packaging drum 4 moves forward along the edges of the left limit frame 503 and the right limit frame 507, the guide wheel 505 will rotate, thereby reducing the friction between the limit frame and the packaging drum 4 and reducing the risk of wear of the packaging drum 4. Simultaneously, the user can rotate the handwheel 609, which will drive the worm gear 608 to rotate. The rotation of the worm gear 608 will drive the worm wheel 607 to rotate, which will drive the drive shaft 606 to rotate. The rotation of the drive shaft 606 will drive the gear 605 to rotate, which will cause the left L-shaped frame 601 and the right L-shaped frame 602 to unfold or close. During the unfolding or closing of the left L-shaped frame 601 and the right L-shaped frame 602, the sliding rod 502 will move back and forth, thereby adjusting the distance between the left limit frame 503 and the right limit frame 507 according to the size of the packaging barrel 4, so as to limit the packaging barrel 4 of different sizes.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
