Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a material blocking device and a roller line. Background Art

[0002] With the increasing automation in the packaging industry, the manual transfer process has been gradually replaced by conveyor lines such as belt lines and roller lines. During the transportation process, products often need to be stopped and wait for the next process to complete. The stop is then released to allow the stopped products to continue to the next process, avoiding collisions between multiple products. At the same time, the products are fixed in a fixed position on the roller line, so that they are aligned with the processing station fixed above the roller line, and then processed.

[0003] In the prior art, the material stopping device is usually arranged under the rotating roller of the roller line, and the baffle of the material stopping device is allowed to pass through the gap between the two rotating rollers by lifting and lowering, thereby stopping the product. Due to the limiting effect of the rotating roller, the stopping device cannot be moved, and thus the stopping position cannot be adjusted according to the size of the product, and the product cannot be centered with the product processing station above the roller line. If the product cannot be centered with the processing station, the processing station will not be able to process the product, and thus it cannot be compatible with the stopping of products of various specifications, which greatly reduces the application range of the equipment; and, since the roller line is usually not high from the ground, and there are multiple wiring grooves under the roller line, the space between the roller line and the ground is narrow, which is not convenient for the installation and maintenance of the material stopping device.

[0004] In order to solve the shortcomings of the existing technology, the utility model provides a material blocking device and a roller line, which solves the problem that the material blocking device cannot be compatible with products of various specifications, greatly reducing the application range of the equipment; it also avoids the problem that the material blocking device is inconvenient to install and maintain when it is installed under the rotating roller of the roller line.

[0039] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1:

[0042] Please see the attached Figure 1 ~Attached Figure 4 The material blocking device 1 of the present invention includes a fixing seat 10 and a material blocking mechanism 20.

[0043] Among them, see Figure 1 , Figure 1 The diagram illustrates the structural relationship between the fixed base 10, the adjustment assembly 22, and the stop assembly 23 in an embodiment of the present invention. Specifically, the fixed base 10 is used to be connected above the roller line 2; the material blocking mechanism 20 is connected to the fixed base 10, and the material blocking mechanism 20 includes a connecting plate 21, an adjustment assembly 22, and a stop assembly 23. The two connecting plates 21 are relatively connected to the fixed base 10, and an adjustment space 211 is formed between the two connecting plates 21. The adjustment assembly 22 is located in the adjustment space 211, and its two ends are relatively inserted through the two connecting plates 21. The stop assembly 23 is sleeved on the adjustment assembly 22. By rotating the adjustment assembly 22, the stop assembly 23 moves within the adjustment space 211 along the transport direction of the roller line 2.

[0044] In this embodiment, the material blocking mechanism 20 is connected to the fixing seat 10 , so that the material blocking mechanism 20 is fixedly installed above the roller line 2 for blocking the material being transported on the roller line 2 . Since an adjustment space 211 is formed between the two connecting plates 21, and the adjustment component 22 is located in the adjustment space 211, the adjustment component 22 can be rotated to make the stopping component 23 connected to the adjustment component 22 move in the adjustment space 211 along the conveying direction of the roller line 2; in this way, when the circumference of the material transported on the roller line 2 is small, the adjustment component 22 can be rotated to make the stopping component 23 move in the opposite direction of material conveying, thereby making the stopping component 23 stop the material in the preset position, ensuring that the material is centered and aligned with the processing station fixed above the roller line 2, thereby ensuring the reliability of the processing of the material at the processing station; and when the circumference of the material transported on the roller line 2 is large, the adjustment component 22 can be rotated to make the stopping component 23 move in the direction of material conveying, thereby making the stopping component 23 stop the material in the preset position and align it with the processing station fixed above the roller line 2, ensuring that the processing station can smoothly process the material, thereby improving the reliability of the material blocking device 1.

[0045] It can be understood that in the technical field of automatic packaging, a film bag is placed inside the box, and the film bag contains materials. When the film bag containing the materials is placed into the box and the bag opening is folded, the bag opening needs to be further laminated; the roller line 2 transports the above-mentioned box that needs to be laminated to the laminating station, and the stop component 23 stops the box in a position aligned with the center of the laminating station so that the laminating station can laminate the box. Since the laminating device is fixedly arranged above the roller line 2, the stop component 23 can be moved along the transport direction of the roller line 2 by rotating the adjustment component 22, so as to be compatible with boxes of different specifications and sizes and enhance the overall application range of the equipment.

[0046] In the aforementioned material retaining device 1, the retaining assembly 23 is sleeved on the adjusting assembly 22. By rotating the adjusting assembly 22, the retaining assembly 23 is moved within the adjusting space 211 along the transport direction of the roller line 2. This allows the retaining assembly 23 to be compatible with materials of different specifications and sizes, ensuring that the materials are aligned with the center of the processing station fixed above the roller line 2, thereby improving the overall application range of the equipment. This solves the problem that the retaining device 1 is unable to accommodate the retaining of products of various specifications, which greatly reduces the application range of the equipment. Moreover, since the retaining device 1 is located above the roller line 2, it is also easy to install and maintain. This solves the problem that the retaining device 1 is inconvenient to install and maintain when it is installed below the rotating roller 40 of the roller line 2.

[0047] In some preferred embodiments, see Figure 2 , Figure 2 The diagram illustrates the structural relationship between the adjustment screw 221 and the stop assembly 23 in an embodiment of the present invention. Specifically, the adjustment assembly 22 includes an adjustment screw 221 and an adjustment structure 222. The two ends of the adjustment screw 221 are oppositely positioned through the two connecting plates 21. The stop assembly 23 is sleeved onto the adjustment screw 221, and the adjustment structure 222 is connected to the end of the adjustment screw 221. By rotating the adjustment structure 222, the adjustment screw 221 is driven to rotate, which further drives the stop assembly 23 to move within the adjustment space 211 along the conveying direction of the roller line 2, ensuring the reliability of the stop assembly 23. Preferably, the adjustment structure 222 is disposed on the side of the connecting plate 21 facing away from the adjustment space 211 to facilitate rotation of the adjustment structure 222.

[0048] In some preferred embodiments, the adjustment structure 222 includes a rotor 2221 and a rotating handle 2222. The rotor 2221 is connected to the end of the adjustment screw 221, and the rotating handle 2222 is sleeved on the rotor 2221. The rotor 2221 is fixedly connected to the end of the adjustment screw 221. By rotating the rotating handle 2222, the rotor 2221 drives the adjustment screw 221 to rotate, thereby adjusting the position of the stop assembly 23 and improving the reliability of the overall structure.

[0049] In some preferred embodiments, a bearing 2223 is further provided at the connection between the rotor 2221 and the adjusting screw 221. The bearing 2223 is sleeved on the rotor 2221 and connected to the surface of the connecting plate 21 facing away from the adjusting space 211. The rotor 2221 is inserted through the bearing 2223 and connected to the end of the adjusting screw 221, thereby improving the stability of the overall structure. The bearing 2223 allows the rotor 2221 to rotate more smoothly, reducing frictional resistance, thereby making the adjusting screw 221 rotate more smoothly, further making the movement of the stop assembly 23 smoother, and improving the adjustment efficiency of the stop assembly 23.

[0050] In some preferred embodiments, see Figure 3 , Figure 3 The diagram illustrates the structural relationship between the stop assembly 23, the sleeve 223, and the adjusting screw 221 in an embodiment of the present invention. Specifically, the sleeve 223 and the adjusting screw 221 are connected at the socket of the stop assembly 23 and the adjusting screw 221. The sleeve 223 is sleeved on the adjusting screw 221, and bolts are inserted through both the sleeve 223 and the stop assembly 23. The fixing 224 is inserted through both the sleeve 223 and the adjusting screw 221. This ensures a more stable connection between the stop assembly 23 and the adjusting screw 221 and a more compact structure, preventing the stop assembly 23 from falling off the adjusting screw 221 and affecting the stop assembly 23's ability to properly stop the material being transported on the roller line 2.

[0051] In some more preferred embodiments, see Figure 4 , Figure 4 The diagram illustrates the structural relationship between the slide rail 241 and the first slider 242 in an embodiment of the present invention. Specifically, the material retaining mechanism 20 further includes a sliding assembly 24, which is connected to the fixed base 10 and abuts the two connecting plates 21 at both ends. The stop assembly 23 is slidably connected to the fixed base 10 via the sliding assembly 24. This ensures that when the stop position of the stop assembly 23 is adjusted, the stop assembly 23 slides more smoothly and stably within the adjustment space 211, thereby extending the service life of the entire structure.

[0052] Furthermore, the sliding assembly 24 includes a slide rail 241 and a first slider 242. The slide rail 241 is connected to the fixed seat 10. The first slider 242 is connected to the stop assembly 23. The first slider 242 is slidably connected to the slide rail 241. The reliability of the sliding connection of the stop mechanism to the fixed seat 10 is ensured.

[0053] Example 2:

[0054] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the material blocking device 1 of the utility model. Figure 5 .

[0055] Among them, seeFigure 5 , Figure 5 The diagram illustrates the structural relationship between the stop lever 231, the support 232, and the driving member 233 in an embodiment of the present invention. Specifically, the stop assembly 23 includes a stop lever 231, a support 232, and a driving member 233. The stop lever 231 includes a stop lever portion 2311, a shaft portion 2312, and a rotating portion 2313 connected in sequence. The shaft portion 2312 is pivotally connected to the support 232, and the rotating portion 2313 is provided with a groove 231a. A second slider 234 is provided at the end of the driving member 233. The second slider 234 is slidably arranged in the groove 231a. During the sliding process of the second slider 234, the stop lever 231 is pushed to rotate relative to the support 232.

[0056] In this embodiment, the driving member 233 drives the second slider 234 to slide, and the sliding of the second slider 234 drives the stopping rod 231 to rotate relative to the support 232. Specifically, the second slider 234 slides within the groove 231a, driving the rotating portion 2313 to rotate, and then driving the rotating shaft portion 2312 and the shift lever portion 2311 to rotate, so that the stopping rod 231 switches between a stopping state and a release state. In the stopping state, the shift lever portion 2311 is perpendicular to the conveying direction of the roller line 2 to stop the material at a preset position on the roller line 2; in the release state, the shift lever portion 2311 is parallel to the conveying direction of the roller line 2 to transport the material along the roller line 2 to the next workstation. It can be understood that the second slider 234 slides to drive the stopping rod 231 to rotate relative to the support 232. Since the rotating shaft portion 2312 of the stopping rod 231 is pivotally connected to the support 232, the rotation speed of the stopping rod 231 is faster when the second slider 234 slides, thereby improving the stopping efficiency of the stopping rod 231; and the structure is more compact, thereby improving the reliability of the overall structure.

[0057] In some preferred embodiments, the driving member 233 includes a driving cylinder 2331 and a telescopic rod 2332. The driving cylinder 2331 is connected to the support 232, and the telescopic rod 2332 is connected between the driving cylinder 2331 and the second slider 234. The driving cylinder 2331 drives the telescopic rod 2332 to extend and retract, thereby driving the second slider 234 to slide within the groove 231a of the rotating portion 2313. When the telescopic rod 2332 extends, it pushes the second slider 234 out, causing the stop rod 231 to be perpendicular to the conveying direction of the roller line 2, achieving a stopped state. When the telescopic rod 2332 retracts, it pulls the second slider 234 back, causing the stop rod 231 to be parallel to the conveying direction of the roller line 2, achieving a released state. Preferably, the driving member 233 can be a cylinder or a motor, the driving cylinder 2331 can be a cylinder, and the telescopic rod 2332 can be a piston rod.

[0058] In some more preferred embodiments, the extending direction of the groove 231a of the rotating portion 2313 forms an obtuse angle with the extending direction of the stop rod 2311. This improves the reliability of the stop rod 231 in stopping materials. Preferably, the groove 231a is a waist-shaped groove, so that when the second slider 234 slides within the groove 231a, the stop rod 231 can smoothly switch between the stop and release states.

[0059] Example 3:

[0060] This embodiment provides a roller line 2 based on the above embodiment. Figure 6 .

[0061] A roller line 2 includes two side plates 30, a plurality of rotating rollers 40 and the above-mentioned material blocking device 1.

[0062] Among them, see Figure 6 , Figure 6 The diagram illustrates the structural relationship between the side panels 30 and the material stopper 1 in an embodiment of the present invention. Specifically, the two side panels 30 are positioned opposite each other to form a conveying space 31. Several rotating rollers 40 are spaced apart within the conveying space 31, with their ends connected to the two side panels 30. The material stopper 1 is connected to the side panels 30, and the stopper rod 231 is rotated to align it parallel or perpendicular to the conveying direction of the conveying space 31.

[0063] In this embodiment, the rotation of the plurality of rotating rollers 40 drives the material placed on the plurality of rotating rollers 40 to achieve conveyance. The two side plates 30 at both ends of the rotating rollers 40 fix the material in the conveying space 31 to ensure stable material conveyance. When the material is conveyed to the preset position, the material blocking device 1 is stopped, and the stopping rod 231 is perpendicular to the conveying direction of the conveying space 31, that is, the stopping rod 231 is perpendicular to the conveying direction of the roller line 2, so as to stop the material at the preset position, making it easier for other processing stations to process the material. After the processing is completed, the material blocking device 1 switches to the release state, and the stopping rod 231 is parallel to the conveying direction of the conveying space 31, that is, the stopping rod 231 is parallel to the conveying direction of the roller line 2, and the rotating rollers 40 rotate to convey the material to the next station.

[0064] In the roller line 2 of the present invention, the stop assembly 23 is sleeved on the adjustment assembly 22. By rotating the adjustment assembly 22, the stop assembly 23 is moved within the adjustment space 211 along the transport direction of the roller line 2. This allows the stop assembly 23 to be compatible with materials of different specifications and sizes, ensuring that the materials are aligned with the center of the processing station fixed above the roller line 2, thereby improving the overall application range of the equipment. This solves the problem that the material stop device 1 is unable to be compatible with the stop of products of various specifications, which greatly reduces the application range of the equipment. In addition, since the material stop device 1 is arranged above the roller line 2, it is also easy to install and maintain. This solves the problem that the material stop device 1 is inconvenient to install and maintain when it is installed below the rotating roller 40 of the roller line 2.
