Description

Technical Field

[0001] The utility model relates to the technical field of automatic packaging, in particular to a material dividing device and a case opening machine. Background Art

[0002] Automatic carton openers, also known as automatic carton bottom-forming and sealing machines, are specialized devices that open the carton boards, fold the bottom according to a specific procedure, and seal with tape before feeding it to the case packer. These machines are production line equipment that automatically open cartons, fold the bottom lid, and seal the bottom with tape for large quantities of cartons. These machines utilize a PLC and display screen control system, completing the entire packaging process from carton opening and unpacking to forming, bottom folding, and bottom sealing in one go. This greatly facilitates operation and is essential for automated large-scale production.

[0003] In existing horizontal automatic carton openers, the sorting mechanism separates stacked cartons into a fixed number for opening by the device and then performing bottom sealing and other processes. Specifically, the sorting plate and the unloading plate are fixedly connected to the same swing arm from top to bottom. The swing arm swings to alternately receive cartons. When the sorting plate extends, the unloading plate retracts to separate a fixed number of cartons. However, controlling the extension and retraction of the sorting plate and unloading plate by swinging can easily cause jamming during operation, leading to cartons falling out and affecting normal production.

[0004] Therefore, it is urgent to solve the problem of jamming when switching between the dividing plate and the unloading plate. Utility Model Content

[0044] 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.

[0045] 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.

[0046] Example 1:

[0047] Please see the attached Figures 1 to 3 The material dividing device of the present invention includes a fixing frame 1 and two material dividing modules 2.

[0048] Please combine Figure 1 and Figure 2 , Figure 1 The diagram shows the structural relationship between the fixing frame 1 and the two material distribution modules 2 in the embodiment of the present utility model. Figure 2The diagram illustrates the structural relationship between the transmission assembly 23 and the first and second blocking assemblies 21, 22, respectively, in an embodiment of the present invention. Specifically, the two material-dividing modules 2 are arranged relative to each other on the fixed frame 1, and a working space 3 for accommodating materials to be divided is formed between the two material-dividing modules 2; the material-dividing modules 2 include a first blocking assembly 21, a second blocking assembly 22, and a transmission assembly 23; the first and second blocking assemblies 21, 22 are slidably arranged in parallel, and the transmission assembly 23 includes a transmission rod group 231 and a driving member 232 for driving the transmission rod group 231 to swing. The opposite ends of the transmission rod group 231 are respectively connected to the first and second blocking assemblies 21, 22, and the first and second blocking assemblies 21, 22 slide horizontally into and out of the working space 3 in opposite directions by swinging.

[0049] In this embodiment, the second blocking assembly 22 is slidably disposed parallel to the bottom of the first blocking assembly 21, and the two ends of the transmission rod group 231 of the transmission assembly 23 are respectively connected to the first blocking assembly 21 and the second blocking assembly 22, so that the first blocking assembly 21 and the second blocking assembly 22 can slide into and out of the working space 3 between the two distributing modules 2 in opposite directions. Specifically, the driving member 232 drives the transmission rod group 231 to swing, and the swing of the transmission rod group 231 causes the first blocking assembly 21 connected to the first end of the transmission rod group 231 to slide into the working space 3 and the second blocking assembly 22 connected to the second end of the transmission rod group 231 to slide out of the working space 3, or when the second blocking assembly 22 slides into the working space 3, the first blocking assembly 21 slides out of the working space 3. It should be noted that both material separation modules 2 are provided with a first blocking component 21, a second blocking component 22 and a transmission component 23, and the two material separation modules 2 are arranged relative to each other to form a working space 3, and the required materials to be separated are accommodated in the working space 3; when working, the first blocking component 21 slides into the working space 3 and supports the materials to be separated. When the first blocking component 21 slides out of the working space 3, the materials to be separated fall into the second blocking component 22, and then the first blocking component 21 slides into the working space 3 again to insert and extract the materials to be separated, that is, to split the materials to be separated. At the same time, the second blocking component 22 slides out of the working space 3 so that the separated materials fall into the next workstation to complete the material separation.

[0050] The above-mentioned material dividing device connects the first blocking component 21 and the second blocking component 22 respectively by setting a transmission rod group 231, and the second blocking component 22 can be slidably arranged in parallel below the first blocking component 21, and the driving member 232 drives the transmission rod group 231 to swing, so that the first blocking component 21 and the second blocking component 22 can slide in and out of the working space 3 between the two material dividing modules 2 in opposite directions. The first blocking component 21 and the second blocking component 22 slide in and out of the working space 3 alternately to separate the materials to be divided, avoiding the problem of jamming easily caused by controlling the extension and contraction of the dividing plate 212 and the discharge plate 222 by swinging, and further avoiding the problem of box dropping.

[0051] In some preferred embodiments, see Figure 3 , Figure 3 The diagram illustrates the structural relationship between the first rail group 24 and the second rail group 25 in an embodiment of the present invention. Specifically, the material dispensing module 2 also includes a first rail group 24 and a second rail group 25 arranged parallel to and below the first rail group 24. The first blocking assembly 21 is slidably connected to the first rail group 24, and the second blocking assembly 22 is slidably connected to the second rail group 25. The first blocking assembly 21 slides into and / or out of the workspace 3 through the first rail group 24, and the second blocking assembly 22 slides into and / or out of the workspace 3 through the second rail group 25. The first rail group 24 and the second rail group 25 do not interfere with each other, so that the first blocking assembly 21 and the second blocking assembly 22 can alternately receive and dispense materials more smoothly, thereby ensuring the stability of the overall structure.

[0052] In some preferred embodiments, the first rail assembly 24 includes two parallel first rails 241, and the first blocking assembly 21 is slidably connected across the two first rails 241; and / or the second rail assembly 25 includes two parallel second rails 251, and the second blocking assembly 22 is slidably connected across the two second rails 251. This makes the connection between the first blocking assembly 21 and the first rail assembly 24, the second blocking assembly 22, and the second rail assembly 25 more stable, making the sliding of the first blocking assembly 21 and / or the second blocking assembly 22 smoother, thereby preventing the problem of materials to be separated falling during operation.

[0053] In some more preferred embodiments, the first blocking assembly 21 includes a first blocking seat 211, a material separation plate 212 and two first sliders 213 connected at both ends of the first blocking seat 211, the two first sliders 213 are respectively slidably connected to the two first slide rails 241, and the material separation plate 212 is connected to the side of the first blocking seat 211 close to the working space 3; and / or the second blocking assembly 22 includes a second blocking seat 221, a material discharge plate 222 and two second sliders 223 connected at both ends of the second blocking seat 221, the two second sliders 223 are respectively slidably connected to the two second slide rails 251, and the material discharge plate 222 is connected to the side of the second blocking seat 221 close to the working space 3.

[0054] It can be understood that in some other embodiments, the slide rail and the slider can be set in the middle part of the material distribution module 2, so that the sliding connection between the material distribution module 2 body and the first blocking component 21 or the second blocking component 22 can be completed by a slide rail and a slider matching it.

[0055] In this embodiment, the two first sliders 213 slidably cooperate with the two first slide rails 241, and the two second sliders 223 slidably cooperate with the two second slide rails 251, so that the first blocking seat 211 and / or the second blocking seat 221 slide more smoothly and have a strong structural stability. The material separation plate 212 is disposed on the side of the first blocking seat 211 near the workspace 3, and the material discharge plate 222 is disposed on the side of the second blocking seat 221 near the workspace 3, and is used to alternately receive the materials to be separated. The material separation plate 212 and the material discharge plate 222 of the oppositely disposed material separation module 2 cooperate with each other to ensure that the materials to be separated are stably placed in the workspace 3. It is understood that the material separation plate 212 and / or the material discharge plate 222 can be respectively connected to the first blocking seat 211 and / or the second blocking seat 221 by welding, clamping, or crimping. Preferably, the materials to be separated can be items such as cartons and cardboard.

[0056] Example 2:

[0057] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the material distribution device of the utility model. Figures 4 to 7 .

[0058] Among them, see Figure 4 , Figure 4The diagram illustrates the structural relationship between the first adjustment structure 2111, the first blocking seat 211, and the material separator 212, and the structural relationship between the second adjustment structure 2211, the second blocking seat 221, and the material discharge plate 222, in an embodiment of the present invention. Specifically, the first adjustment structure 2111 is provided at the connection between the first blocking seat 211 and the material separator 212 to adjust the distance between the material separator 212 and the material discharge plate 222; and / or the second adjustment structure 2211 is provided at the connection between the second blocking seat 221 and the material discharge plate 222 to adjust the distance between the material discharge plate 222 and the material separator 212.

[0059] In this embodiment, by adjusting the distance between the material separation plate 212 and the material discharge plate 222, the amount of material to be separated can be adjusted to meet different material separation requirements. It can be understood that during the operation of the horizontal automatic carton opener, the material separation device is required to separate a certain amount of cartons from the stacked cartons for the carton opening mechanism to open and then perform processes such as bottom sealing. When the material to be separated is a large-sized and heavy carton, if too many cartons are separated at one time, the suction cup of the carton opening device will be affected by friction resistance and will not be able to smoothly suck up the cartons. At this time, by adjusting the distance between the material separation plate 212 and the material discharge plate 222, the material separation device can be quantitatively separated to allow the carton opening device to smoothly suck up.

[0060] In some preferred embodiments, see Figure 5 , Figure 5 The specific structure of the first adjustment structure 2111 and / or the second adjustment structure 2211 in an embodiment of the present invention is illustrated. Specifically, the first adjustment structure 2111 includes a first mounting portion 211a connected to the first blocking seat 211, the first mounting portion 211a having a first mounting hole 211b, the material distributor 212 being connected to the first mounting hole 211b, and the first mounting hole 211b being a waist-shaped hole; and / or the second adjustment structure 2211 includes a second mounting portion 221a connected to the second blocking seat 221, the second mounting portion 221a having a second mounting hole 221b, the material discharge plate 222 being connected to the second mounting hole 221b, and the second mounting hole 221b being a waist-shaped hole. Since the first mounting hole 211b and / or the second mounting hole 221b are waist-shaped holes, when installing the material distributor 212 and / or the feed plate, the spacing between the material distributor 212 and the feed plate can be adjusted by adjusting the position of the material distributor 212 and / or the feed plate installed in the waist-shaped hole. Preferably, bolts can be simultaneously passed through the material dividing plate 212 and the first mounting hole 211b to make the connection between the material dividing plate 212 and the first blocking seat 211 more stable, and bolts can be simultaneously passed through the material discharge plate 222 and the second mounting hole 221b to make the connection between the material discharge plate 222 and the second blocking seat 221 more stable.

[0061] In some preferred embodiments, there are multiple material dividing plates 212, which are spaced apart on the side of the first blocking seat 211 close to the workspace 3; and / or there are multiple material discharging plates 222, which are spaced apart on the side of the second blocking seat 221 close to the workspace 3. This provides better support for the materials to be separated, and the multiple material dividing plates 212 and / or the multiple material discharging plates 222 are evenly spaced apart on the first blocking seat 211 and / or the second blocking seat 221, thereby evenly distributing the weight of the materials to be separated, ensuring the balance of the materials to be separated, thereby preventing the materials to be separated from falling, and extending the service life of the overall structure.

[0062] Furthermore, the plurality of material separation plates 212 and the plurality of material discharge plates 222 are arranged relative to each other to ensure the stability of the materials to be separated.

[0063] In some preferred embodiments, see Figure 6 , Figure 6 The diagram illustrates the structural relationship between the transmission rod 2311, the swing shaft 2312, and the swing arm 2313 in an embodiment of the present invention. Specifically, the transmission rod assembly 231 includes the transmission rod 2311, the swing shaft 2312, and the swing arm 2313. The transmission rod 2311 is connected to the first and second blocking assemblies 21 and 22 at both ends, respectively. The swing shaft 2312 extends through the transmission rod 2311 and is rotatably connected to opposite ends of the fixed frame 1 at both ends. One end of the swing arm 2313 is sleeved on the swing shaft 2312, and the other end is connected to the driving member 232. The driving member 232 drives the swing arm 2313 to move up and down. The movement of the swing arm 2313 rotates the swing shaft 2312, which in turn drives the transmission rod 2311 to swing. The transmission rod 2311 drives the first and second blocking assemblies 21 and 22 to slide in and out of the workspace 3 in opposite directions, so that the first and second blocking assemblies 21 and 22 alternately receive and separate materials, ensuring the reliability of the overall structure.

[0064] In some preferred embodiments, the cross-section of the swing shaft 2312 is a non-rotating surface, and the inner surface of the swing arm 2313 is in contact with the outer surface of the swing shaft 2312. This provides a more stable connection between the swing shaft 2312 and the swing arm 2313, and improves the reliability of the swing arm 2313 in driving the swing shaft 2312 to rotate. Preferably, the swing shaft 2312 is in the shape of a square bar, and the inner surface of the swing arm 2313 is a square opening that fits in the square bar.

[0065] In some more preferred embodiments, see Figure 7 , Figure 7The diagram illustrates the structural relationship between the transmission rod 2311 and the first and second blocking assemblies 21 and 22, respectively, in an embodiment of the present invention. Specifically, a first connecting portion 214 extends from the connection between the first blocking assembly 21 and the transmission rod 2311, and a second connecting portion 224 extends from the connection between the second blocking assembly 22 and the transmission rod 2311. Sliding holes 231a are respectively defined at each end of the transmission rod 2311, each of which is movably coupled to the first and second connecting portions 214 and 224. As the first and second blocking assemblies 21 and 22 alternately slide into and out of the workspace 3, the first and / or second connecting portions 214 and 224 slide within the sliding holes 231a, ensuring the sliding reliability of the first and / or second blocking assemblies 21 and 22. Preferably, the sliding holes 231a are waist-shaped holes to increase the sliding space of the first and / or second blocking assemblies 21 and 22.

[0066] Example 3:

[0067] This embodiment provides a box opening machine based on the above embodiments.

[0068] A case opening machine comprises a case opening device and a material dividing device.

[0069] Among them, the carton opening device is arranged adjacent to the material separating device, and the carton opening device is used to suck and open the cartons separated by the material separating device.

[0070] In this embodiment, after the separating plate 212 of the first blocking component 21 separates the carton, the second blocking component 22 slides out of the working space 3 to allow the carton to fall into the carton opening device, which sucks the carton and opens it to complete the carton opening work.

[0071] The carton opener of the present invention connects the first blocking component 21 and the second blocking component 22 respectively by setting a transmission rod group 231, and the second blocking component 22 can be slidably arranged in parallel below the first blocking component 21, and the driving member 232 drives the transmission rod group 231 to swing, so that the first blocking component 21 and the second blocking component 22 can slide into and out of the working space 3 between the two material dividing modules 2 in opposite directions. The first blocking component 21 and the second blocking component 22 slide into and out of the working space 3 alternately to separate the materials to be divided, avoiding the problem of jamming easily caused by controlling the extension and contraction of the dividing plate 212 and the discharge plate 222 by swinging, and further avoiding the problem of box dropping.
