Description

Technical Field

[0001] The embodiments of the present utility model relate to the technical field of packaging equipment. More specifically, the present utility model relates to a quick installation structure of a conveyor and a material bin. Background Art

[0002] This section aims to provide background or context for the embodiments of the present utility model stated in the claims. The descriptions herein may include concepts that can be explored, but not necessarily concepts that have been previously thought of or explored. Therefore, unless otherwise indicated herein, the content described in this section is not prior art for the specification and claims of this application, and is not admitted to be prior art merely by being included in this section.

[0003] In some automated packaging equipment or production lines, for some products such as packaging papers, instruction manuals or thin sheets, corresponding conveying mechanisms are required to input them from outside the equipment into the equipment for use. Generally, the materials are sorted and stacked and then placed in a bin with a conveyor. The materials are transported to a fixed position through the intermittent movement of the conveyor, and then the materials are taken out of the bin one by one through the material taking mechanism inside the equipment.

[0004] When there are multiple channels of paper bins in parallel in the equipment and there are various specifications of papers in actual production. When switching production specifications, the bin needs to be reconfigured according to actual needs to adapt to the new specification of paper. At this time, the conveyor needs to change its position in the bin to adapt to the new specification of paper. There are two existing solutions in the market:

[0005] One is to sequentially adjust the up and down position of the conveyor through two horizontal and vertical lead screws. This solution is friendly to single channels. When there are multiple channels, due to a series of guiding parts such as lead screws, the intercept between each channel will be relatively large, the overall space occupation will be very large, and there will be redundant parts.

[0006] The other is to replace the bin as a whole. First, the conveyor is removed from the bin. After replacing the new bin panel, the conveyor is reinstalled on the new bin panel. This method can make the overall space occupation of the mechanism more reasonable. The disassembly and assembly of the conveyor from the bin panel mainly rely on fixing methods such as screwing in bolts, and the operation is relatively cumbersome. Summary of the Utility Model

[0041] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0042] As Figures 1 to 5 shown, the embodiment of the present utility model provides a quick-change cardboard bin, including: a fixed frame 1, on which a first pneumatic joint 12 is provided; a bin panel 3, the bottom end of the bin panel 3 is detachably hinged to the fixed frame 1, a second pneumatic joint 301 is provided on the bin panel 3, the first pneumatic joint 12 and / or the second pneumatic joint 301 are arranged to be able to float in the radial direction of the rotation of the bin panel 3, and the second pneumatic joint 301 is in plug-in fit with the first pneumatic joint 12; a conveying channel 4 is provided on the bin panel 3; a locking member 2 for locking and fixing the bin panel 3 on the fixed frame 1 and releasing the bin panel 3; a conveyor 5 detachably arranged in the conveying channel 4; a fastening structure 6 for fixing the conveyor 5 in the conveying channel 4 and releasing the conveyor 5.

[0043] In this embodiment, the cardboard bin mainly includes a fixed frame 1, a bin panel 3, a conveyor 5, a locking member 2 and a fastening structure 6. Among them, the fixed frame 1 is the frame structure in the cardboard bin, and the fixed frame 1 can be placed on the feeding station of the cardboard as the installation basis for other components such as the bin panel 3. Since the cardboard needs to be fed through the fixed frame 1, a hole with a certain area will be opened on the fixed frame 1, and this hole can be set as a hole structure 101 similar to and corresponding to the conveying channel 4 on the bin panel 3, or as Figure 2 shown, it can be set as a hole structure 101 much larger than the conveying channel 4 and corresponding to the bin panel 3.

[0044] The silo panel 3 is generally in a plate-like structure and can be installed on the fixed frame 1. To achieve cardboard feeding, a conveying channel 4 is provided on the silo panel 3, and this conveying channel 4 corresponds to the pore structure 101 on the fixed frame 1. The specific structural form of the conveying channel 4 needs to be designed according to the shape of the cardboard to be fed, and this embodiment does not limit it here. The number of the conveying channels 4 can be set to one or more according to different production processes, and this embodiment does not limit it here either.

[0045] In this embodiment, the silo panel 3 and the fixed frame 1 are connected by a hinged manner. After the silo panel 3 is installed on the fixed frame 1, it can be rotated to the installation position. Similarly, during disassembly, the silo panel 3 can also be rotated to the disassembly position to complete the disassembly. Compared with the installation method in the related art of integrally clamping the silo panel 3, the hinged installation method of the silo panel 3 does not require alignment at multiple positions during installation, and the device for hinging the silo panel 3 on the fixed frame 1 can support the silo panel 3 during installation, making the installation and disassembly of the silo panel 3 more convenient.

[0046] In a hinged implementation manner of the silo panel 3 and the fixed frame 1, as Figure 4 shown, a horizontal axis 10 is provided on the fixed frame 1, and a card slot 11 capable of being clamped with the horizontal axis 10 is provided at the bottom end of the silo panel 3. During installation, the silo panel 3 can be first inclined and inserted into the fixed frame 1 to make the card slot 11 clamped with the horizontal axis 10, and then the silo panel 3 can be rotated around the axis of the horizontal axis 10 to the installation position. During disassembly, the silo panel 3 is rotated in the reverse direction to the disassembly position and then pulled outwards to make the card slot 11 separated from the horizontal axis 10. In this embodiment, the horizontal axis 10 can be a long-axis structure or short axes distributed on both sides of the fixed frame 1.

[0047] It can be understood that the horizontal axis 10 can also be provided on the silo panel 3, and the card slot 11 can be provided on the fixed frame 1, as long as they can maintain a hinged connection state after being clamped.

[0048] In another hinged implementation manner of the silo panel 3 and the fixed frame 1, a rotatable clamping member can be provided on the fixed frame 1, and another clamping member is fixed on the silo panel 3. The silo panel 3 is installed on the fixed frame 1 through the clamping of the two clamping members, and then the silo panel 3 is rotated to drive the clamping member on the fixed frame 1 to rotate, thereby installing the silo panel 3 to the installation position.

[0049] In addition, it should be noted that the card slot 11 can be a structure provided at the lower end of the silo panel 3 (as Figure 4 shown), or can be a structure on the back of the silo panel 3.

[0050] Since the silo panel 3 in this embodiment is installed and disassembled by rotating around the horizontal axis 10, when a small section of the circumferential movement of the silo panel 3 is intercepted, this section of the movement trajectory is close to a straight line. When intercepting the same length of the movement section, the position farther away from the horizontal axis 10 is closer to a straight line. Since the insertion and matching of the first pneumatic joint 12 and the second pneumatic joint 301 need to be completed synchronously when installing the silo panel 3, and the disconnection of the first pneumatic joint 12 and the second pneumatic joint 301 needs to be completed synchronously when disassembling. Considering that both the connection and disconnection of the first pneumatic joint 12 and the second pneumatic joint 301 are linear movements, the first pneumatic joint 12 and the second pneumatic joint 301 need to be as far away from the horizontal axis 10 as possible. In this embodiment, the first pneumatic joint 12 and the second pneumatic joint 301 are correspondingly arranged. Therefore, the second pneumatic joint 301 on the silo panel 3 is arranged at the upper end of the silo panel 3, and the horizontal axis 10 is located at the lower end of the silo panel 3 to make the distance between the two far enough.

[0051] On this basis, when the first pneumatic joint 12 and the second pneumatic joint 301 need to have a certain insertion depth, in order to synchronously complete the pneumatic connection during the rotation of the silo panel 3, at least one of the first pneumatic joint 12 and the second pneumatic joint 301 is set as a floating joint in this embodiment. Specifically, taking the first pneumatic joint 12 being set as a floating joint as an example, the floating direction of the first pneumatic joint 12 is the radial direction of the rotation circumference of the silo panel 3. When the second pneumatic joint 301 contacts the first pneumatic joint 12 as the silo panel 3 rotates, as the silo panel 3 further rotates, the insertion depth of the first pneumatic joint 12 and the second pneumatic joint 301 gradually increases. During this process, the first pneumatic joint 12 generates a certain amount of radial floating to meet the insertion depth requirements of the first pneumatic joint 12 and the second pneumatic joint 301.

[0052] As Figure 4a shown, O is the rotation center of the silo panel 3, R is the distance from O to the first pneumatic joint 12, A1 is the position where the second pneumatic joint 301 and the first pneumatic joint 12 just contact, A2 is the position of the second pneumatic joint 301 after the second pneumatic joint 301 and the first pneumatic joint 12 are inserted in place, L is the rotation trajectory of the second pneumatic joint 301, and the maximum vertical distance from the part of L between A1 and A2 to the connection line of A1 and A2 is the maximum displacement D of the pneumatic joint. The floating amount of the first pneumatic joint 12 should be greater than or equal to the maximum displacement D. When designing the product, the distance from A1 to A2 (i.e., the insertion depth) and the floating amount can be determined first, and then R that meets the composite conditions can be obtained by inverse calculation, that is, the layout positions of the first pneumatic joint 12 and the second pneumatic joint 301 are obtained by inverse calculation. When the first pneumatic joint 12 has multiple interfaces in the radial direction, the calculation can be carried out at the interface position closest to the rotation center.

[0053] Since the bin panel 3 and the fixed frame 1 are hinged, in order to fix the bin panel 3 during use, this embodiment realizes it by operating the locking member 2. As Figure 1 and Figure 2 shown, the locking member 2, as a structure for fixing the bin panel 3 after the bin panel 3 rotates to the installation position, can be installed on the fixed frame 1, and the locking member 2 can be operated to fix the bin panel 3 after the bin panel 3 rotates to the installation position.

[0054] In one embodiment of the locking member 2, as Figure 2 shown, the locking member 2 can be a structure hinged on the fixed frame 1. After the bin panel 3 rotates to the installation position, the locking member 2 can be rotated to abut against the outer side surface of the bin panel 3, thereby fixing the bin panel 3.

[0055] In another embodiment of the locking member 2, the locking member 2 can be a plug-like structure, which can be inserted into the bin panel 3 and the fixed frame 1 from the side at the same time, thereby fixing the bin panel 3.

[0056] In yet another embodiment of the locking member 2, the locking member 2 can be a clamp structure. The clamp structure is fixed on the fixed frame 1, and the bin panel 3 is pressed by rotating the clamp.

[0057] After the installation of the bin panel 3 is completed, the conveyor 5 can be installed into the conveying channel 4 of the bin panel 3. The conveying of the cardboard by the conveyor 5 can be realized by driving the conveyor belt 18 to move in a cycle. As Figure 1 and Figure 2 shown, in this embodiment, the conveyor 5 is installed at the bottom end of the conveying channel 4. The cardboard to be loaded is placed in the conveying channel 4 and on the conveyor 5, and the conveyor 5 completes the conveying of the cardboard. An installation groove matching the conveyor 5 can be formed at the bottom end of the conveying channel 4, and the conveyor 5 can be installed into the installation groove.

[0058] In order to fix the conveyor 5 to the conveying channel 4, this embodiment realizes it by operating the fastening structure 6. According to different fastening methods, the fastening structure 6 also has different structures. In one embodiment of the fastening structure 6, the fastening structure 6 can complete the fixation of the conveyor 5 by applying a pressure against the conveyor 5 in the conveying channel 4. In this embodiment, the fastening structure 6 can be a clamp, a fastening screw, etc.

[0059] In this embodiment, when changing the mold, the bottom end of the bin panel 3 can be obliquely butted with the fixed frame 1 first to make the bin panel 3 and the fixed frame 1 in a hinged state, and then the bin panel 3 is rotated to make it close to the fixed frame 1 and rotated to the installation position. During this process, the first pneumatic joint 12 or the second pneumatic joint 301 that can float along the rotation radius can complete the docking synchronously, that is, the air circuit connection between the bin panel 3 and the fixed frame 1 is completed synchronously during the installation of the bin panel 3. Then, the locking member 2 can be operated to fix the bin panel 3. Immediately afterwards, the conveyor 5 can be installed into the conveying channel 4 of the bin panel 3, and then the fastening structure 6 is operated to complete the fixation of the conveyor 5, so as to achieve the technical effect that during the bin mold change process, the bin panel 3 and the conveyor 5 can be quickly changed, and when the bin panel 3 is changed, the alignment is convenient and the air circuit connection can be completed synchronously. Furthermore, it solves the problem that in the bin mold change environment of overall replacement in the related art, the docking of the bin panel 3 is difficult, and the air circuit required for the bin after mold change needs to be connected separately, resulting in inconvenient mold change operation.

[0060] In the present utility model, the conveyor 5 uses gas as the power source, and the supply of gas to the conveyor 5 is realized through an external gas supply device and a corresponding gas channel. Since both the conveyor 5 and the bin panel 3 in the present utility model are replaceable structures, the external gas supply device is preferably connected to the fixed frame 1. Therefore, a gas channel that meets each other needs to be established between the fixed frame 1, the bin panel 3 and the conveyor 5.

[0061] In this embodiment, as Figure 2 shown, a first pneumatic joint 12 is provided on the fixed frame 1, an air passage, a second pneumatic joint 301 communicated with the air passage and a third pneumatic joint 8 are provided on the bin panel 3. As Figure 12 shown, a fourth pneumatic joint 20 is provided on the conveyor 5, and the fourth pneumatic joint 20 is communicated with the pneumatic equipment in the conveyor 5. In this embodiment, the connection between the first pneumatic joint 12 and the second pneumatic joint 301, and the connection between the third pneumatic joint 8 and the fourth pneumatic joint 20 are used to establish the gas channel.

[0062] For the connection between the first pneumatic connector 12 and the second pneumatic connector 301, in this embodiment, it is achieved by plugging. Since the first pneumatic connector 12 is directly arranged on the fixed frame 1, while the second pneumatic connector 301 is directly arranged on the bin panel 3. Therefore, when the bin panel 3 rotates to the installation position, the first pneumatic connector 12 and the second pneumatic connector 301 can be connected synchronously. Similarly, when disassembling, the reverse rotation of the bin panel 3 can also disengage the first pneumatic connector 12 and the second pneumatic connector 301. In other words, during the installation process of the bin panel 3, the connection between the first pneumatic connector 12 and the second gas connector can be completed synchronously, and during the disassembly process of the bin panel 3, the disengagement between the first pneumatic connector 12 and the second pneumatic connector 301 can be completed synchronously.

[0063] For the connection between the third pneumatic connector 8 and the fourth pneumatic connector 20, in this embodiment, it is also achieved by plugging. Since the third pneumatic connector 8 is directly arranged on the bin panel 3, and the fourth pneumatic connector 20 is directly arranged on the conveyor 5. Therefore, when the conveyor 5 is installed into the conveying channel 4 on the bin panel 3, the third pneumatic connector 8 and the fourth pneumatic connector 20 can be connected synchronously. Similarly, when disassembling the conveyor 5, the third pneumatic connector 8 and the fourth pneumatic connector 20 can also be disengaged synchronously. In other words, during the installation process of the conveyor 5, the connection between the third pneumatic connector 8 and the fourth gas connector can be completed synchronously, and during the disassembly process of the conveyor 5, the disengagement between the third pneumatic connector 8 and the fourth pneumatic connector 20 can be completed synchronously.

[0064] The utility model achieves the following through the quick-change cardboard bin: before the mold change, the fastening structure 6 can be operated first to release the fixation of the conveyor 5, and then the conveyor 5 can be removed from the conveying channel 4. During the removal process, the third pneumatic joint 8 and the fourth pneumatic joint 20 are automatically disengaged. Then, the locking member 2 can be operated to release the fixation of the bin panel 3. Immediately afterwards, the bin panel 3 can be rotated. During the rotation process, the first pneumatic joint 12 and the second pneumatic joint 301 are automatically disengaged. After rotating to the set position, the bin panel 3 can be removed from the fixed frame 1. During the mold change, the bin panel 3 can be hinged into the fixed frame 1 first, and the bin panel 3 can be rotated to complete the installation of the bin panel 3 and the connection of the first pneumatic joint 12 and the second pneumatic joint 301. Then, the locking member 2 can be operated to fix the bin panel 3. Then, the conveyor 5 can be installed into the conveying channel 4. By operating the fastening structure 6, the fixation of the conveyor 5 in the conveying channel 4 is completed and the connection of the third pneumatic joint 8 and the fourth pneumatic joint 20 is synchronously completed, so as to achieve the purpose of quickly changing the bin panel 3 and the conveyor 5 during the bin mold change process, and the air circuit of the bin can be disengaged and connected along with the removal and installation of the bin panel 3 and the conveyor 5 during the mold change process, that is, no additional connection of the air circuit is required during the mold change process, making the mold change operation more convenient. Furthermore, it solves the problem that in the bin mold change environment of overall replacement in the related art, the air circuit required by the bin after the mold change needs to be connected separately, resulting in inconvenient mold change operation.

[0065] To realize the conveying function of the cardboard, the conveyor 5 needs to have a certain length. To improve the running stability of the conveyor 5, the conveyor 5 needs to be supported. Therefore, as Figure 1 、 Figure 2 and Figure 5 shown, the quick-change cardboard bin in this embodiment further includes:

[0066] A support arm assembly 7, including a first quick-release structure 702 and a support arm 701. The first quick-release structure 702 is arranged at the first end of the support arm 701. A second quick-release structure 9 is also arranged on the fixed frame 1. The second quick-release structure 9 is quickly connected to the first quick-release structure 702. The second end of the support arm 701 abuts against the lower end of the conveyor 5 to support the conveyor 5.

[0067] In this embodiment, since the conveyor 5 is a replaceable structure, the corresponding support arm assembly 7 also needs to be set as a structure that can be removed from the fixed frame 1 and the conveyor 5, so as to facilitate the replacement of the support arm assembly 7 matching the conveyor 5. Specifically, as Figure 2 and Figure 5As shown, in this embodiment, the support arm assembly 7 mainly includes a first quick-release structure 702 and a support arm 701. The support arm 701 has a certain length and can be connected to the conveyor 5 in an inclined manner, thereby supporting the conveyor 5. The first quick-release structure 702 is a structure installed at one end of the support arm 701 away from the conveyor 5. A second quick-release structure 9 corresponding to the first quick-release structure 702 is provided on the fixed frame 1, and the first quick-release structure 702 and the second quick-release structure 9 can be quickly connected. In an implementation manner of the quick connection, the first quick-release structure 702 and the second quick-release structure 9 can be inserted and matched.

[0068] In this embodiment, the disassembly of the support arm assembly 7 can be after the disassembly of the conveyor 5, and its installation is before the installation of the conveyor 5. For the same conveyor 5, one or more support arm assemblies 7 can be configured. Of course, a support arm assembly 7 can include multiple support arms 701, and multiple support arms 701 can be jointly installed on the same first quick-release structure 702.

[0069] In an implementation manner of the first quick-release structure 702 and the second quick-release structure 9, as Figure 6 and Figure 7 shown, the first quick-release structure 702 includes a first connecting member 7024, and the second quick-release structure 9 includes a second connecting member 901. The first connecting member 7024 and the second connecting member 901 are inserted and matched vertically.

[0070] To facilitate the insertion and matching of the first connecting member 7024 and the second connecting member 901, in this embodiment, both the first connecting member 7024 and the second connecting member 901 are set as wedge-shaped structures. A first insertion slot 902 is formed between the inner side of the second connecting member 901 and the fixed frame 1. The first quick-release structure 702 further includes an outer frame 7020. The first side of the outer frame 7020 is an open structure, and a connecting seat 7025 is provided on the second side of the outer frame 7020. The first end of the support arm 701 is fixed in the connecting seat 7025. A first connecting plate 7021 is provided on the inner side of the outer frame 7020, and a second connecting plate 7023 is provided on the first connecting plate 7021. The second connecting plate 7023 constitutes the wedge-shaped first connecting member 7024, so that a second insertion slot for the insertion of the second connecting member 901 is formed between the second connecting plate 7023 and the first connecting plate 7021.

[0071] During installation, the outer frame 7020 covers the second connecting member 901 and makes the first connecting member 7024 located above the second connecting member 901. At this time, the first insertion slot 902 corresponds to the first connecting member 7024, and the second insertion slot corresponds to the second connecting member 901. Then, the outer frame 7020 can be pushed downward to insert the second connecting member 901 into the second insertion slot to complete the installation.

[0072] To enable the first connecting member 7024 and the second connecting member 901 to be accurately plugged and matched, as Figure 6 shown, the first quick-release structure 702 in this embodiment further includes a positioning member 7022. The positioning member 7022 is provided on both sides of the first connecting member 7024. The lower end of the positioning member 7022 extends out of the lower end surface of the first connecting member 7024. The distance between the positioning members 7022 on both sides matches the length of the second connecting member 901.

[0073] Specifically, it should be noted that an insertion groove matching the second connecting member 901 is formed between the positioning members 7022 on both sides. During installation, the horizontal position of the first connecting member 7024 is initially positioned by the positioning members 7022 on both sides, and the first connecting member 7024 and the second connecting member 901 are vertically aligned. Then, the first connecting member 7024 is inserted into the second connecting member 901 vertically to complete the installation. The setting of the positioning member 7022 enables the first connecting member 7024 and the second connecting member 901 to be completely aligned without misalignment in the length direction, improving the accuracy of the connection.

[0074] In this embodiment, the positioning member 7022 can be a plate structure separately fixed on both sides of the first connecting plate 7021, or a protruding structure integrally formed with the first connecting plate 7021.

[0075] Since the support arm 701 mainly functions to support the conveyor 5, for the convenience of connecting and disassembling the support arm 701 and the conveyor 5, as Figure 6 shown, a connecting groove 7010 is provided at the second end of the support arm 701 in this embodiment, and a connecting shaft is provided at the lower end of the conveyor 5. The connecting shaft is in snap-fit with the connecting groove 7010.

[0076] In one implementation manner of the locking member 2, the locking member 2 is provided on both sides of the fixed frame 1 and can fix both sides of the bin panel 3 simultaneously, thereby further improving the stability of the bin panel 3 after fixation.

[0077] In this implementation manner, as Figure 2 shown, the locking member 2 includes a rotating wrench 201 and a locking buckle 202. The rotating wrench 201 is provided on the fixed frame 1, and the locking buckle 202 is provided on the bin panel 3. The rotating wrench 201 is configured to be rotatably engaged with and disengaged from the locking buckle 202.

[0078] Specifically, the locking buckle 202 is fixed on the outer side of the bin panel 3. One side of the locking buckle 202 close to the rotary wrench 201 is provided with an opening. The rotary wrench 201 is hinged on the fixed frame 1. One side of the rotary wrench 201 close to the locking buckle 202 is provided with a convex block, and the convex block can be rotatably clamped into the opening, so as to fix the bin panel 3 on the fixed frame 1. When it is necessary to remove the bin panel 3, the rotary wrench 201 can be rotated to make the convex block disengage from the locking buckle 202. In this embodiment, the fixing operation of the bin panel 3 on the fixed frame 1 is made more convenient through the locking member 2, and no other auxiliary tools or separate fasteners are required.

[0079] Since the connection between the first pneumatic joint 12 and the second pneumatic joint 301 is synchronously realized during the installation process of the bin panel 3, when the positions of both the first pneumatic joint 12 and the second pneumatic joint 301 are in fixed positions, in order to achieve precise docking, there are relatively high requirements for the position accuracy of the pneumatic joints.

[0080] In this embodiment, in order to reduce the requirements for the position accuracy of the first pneumatic joint 12 and the second pneumatic joint 301, at least one of the first pneumatic joint 12 and the second pneumatic joint 301 is set as a floating joint, that is, one of the pneumatic joints is allowed to float within a certain range, so that the two pneumatic joints can be quickly docked during the installation process of the bin panel 3.

[0081] Specifically, as Figures 8 to 11 shown, in this embodiment, the first pneumatic joint 12 is set as a floating joint. In this embodiment, the first pneumatic joint 12 includes: a joint housing 120, and a joint installation cavity 122 is arranged inside the joint housing 120; a floating member 123 is arranged in the joint installation cavity 122, and the floating member 123 is in clearance fit with the joint installation cavity 122 in the axial direction, and the radial dimension of the joint installation cavity 122 is larger than the radial dimension of the floating member 123, so that the floating member 123 can generate radial floating in the joint installation cavity 122. An access port is arranged on the floating member 123; a quick-change air nozzle 125, the first end of the quick-change air nozzle 125 is fixed in the access port, and the second end extends out of the floating member 123; a quick-insertion hole 3010 communicated with the air passage is arranged inside the second pneumatic joint 301, and the quick-change air nozzle 125 is in plug-in fit with the quick-insertion hole 3010.

[0082] In this embodiment, the joint housing 120 is fixed to the fixed frame 1, specifically, it can be fixed within the duct structure 101 of the fixed frame 1 so as to directly correspond to the silo panel 3. A through joint installation cavity 122 is formed in the joint housing 120. A floating member 123 is arranged in the joint installation cavity 122. A cavity penetrating axially is arranged in the floating member 123. The first end of the cavity can be connected to an external air supply device through an air valve for air inflow. The second end of the cavity is provided with an access port, and a quick-change air nozzle 125 is arranged in the access port for air outflow.

[0083] In this embodiment, the docking of the first pneumatic joint 12 and the second pneumatic joint 301 is essentially the docking of the quick-change air nozzle 125 in the first pneumatic joint 12 and the quick socket 3010 in the second pneumatic joint 301. Therefore, to achieve the floating of the quick-change air nozzle 125, the structures of the joint installation cavity 122 and the floating member 123 are improved in this embodiment. Specifically, in this embodiment, the floating member 123 has a clearance fit with the joint installation cavity 122 axially to prevent the floating member 123 and the joint installation cavity 122 from being axially jammed. And the radial dimension of the joint installation cavity 122 is larger than the radial dimension of the floating member 123. The difference between their radial dimensions is the floating space of the floating member. Based on this floating space, the floating member 123 and the quick-change air nozzle 125 can produce a certain amount of floating relative to the joint installation cavity 122 radially.

[0084] When the quick-change air nozzle 125 is connected to the quick socket 3010, due to the floating space between the floating member 123 and the joint installation cavity 122, the floating member 123 and the quick-change air nozzle 125 can automatically move to a suitable position to adapt to the quick socket 3010, thus completing the connection.

[0085] Based on the above embodiments, to facilitate the docking of the quick replacement air nozzle 125 and the quick insertion hole 3010, in this embodiment, a first guiding surface 1251 is provided at the second end of the quick replacement air nozzle 125, and a second guiding surface 3011 that cooperates with the first guiding surface 1251 is provided at the end of the quick insertion hole 3010. Both the first guiding surface 1251 and the second guiding surface 3011 are conical surfaces. When inserting, the first guiding surface 1251 contacts the second guiding surface 3011 first. At this time, the axis of the quick replacement air nozzle 125 and the axis of the quick insertion hole 3010 may not be collinear. As the silo panel 3 rotates further, the first guiding surface 1251 and the second guiding surface 3011 always remain in contact. Under the cooperation of the two, the quick replacement air nozzle 125 generates radial floating in the floating space, and finally the axis of the quick replacement air nozzle 125 gradually approaches the axis of the quick insertion hole 3010. At this time, the first guiding surface 1251 completely enters the quick insertion hole 3010. Then, during the further rotation of the silo panel 3, the quick replacement air nozzle 125 will continuously float in the floating space to align its position until the quick replacement air nozzle 125 reaches the set insertion depth. In this embodiment, by setting the floating member 123 and the quick replacement air nozzle 125 as floating structures, the requirement for the position accuracy of the first pneumatic joint 12 and the second pneumatic joint 301 is reduced when completing the air path connection between the fixed frame 1 and the silo panel 3, and the connection of the first pneumatic joint 12 and the second pneumatic joint 301 can be better synchronized during the installation process of the silo panel 3.

[0086] It can be understood that in another embodiment, the quick replacement air nozzle 125 can be fixed in the quick insertion hole 3010. The docking of the first pneumatic joint 12 and the second pneumatic joint 301 is actually the docking of the quick replacement air nozzle 125 and the internal connection port in the floating member 123. The specific docking process is the same as the above embodiment, and this embodiment will not elaborate on it here.

[0087] In addition, the second pneumatic joint 301 can also be set as a floating structure with reference to the floating structure of the first pneumatic joint 12, or the second pneumatic joint 301 can be set as a floating structure with reference to the floating structure of the first pneumatic joint 12, while the first pneumatic joint 12 remains a fixed structure. In the above embodiments, the quick replacement air nozzle 125 can be a part of the first pneumatic joint 12 or a part of the second pneumatic joint 301, and this embodiment does not limit it here.

[0088] To prevent the floating member 123 from detaching from the joint installation cavity 122 and to ensure the radial floating space of the floating member 123, in this embodiment, a second limiting portion 124 is provided on the floating member 123. The first limiting portion 121 and the second limiting portion 124 are inserted and matched in the radial direction of the floating member 123, and there is a floating space between the first limiting portion 121 and the second limiting portion 124 in the radial direction of the floating member 123. In this embodiment, the axial end faces of the first limiting portion 121 and the second limiting portion 124 are in clearance fit to prevent the floating member 123 from being pressed against the joint installation cavity 122 and unable to generate radial floating.

[0089] In one implementation manner, the first limiting portion 121 and the second limiting portion 124 can be respectively set as a convex structure and a concave structure. Specifically, in one implementation manner of the first limiting portion 121 and the second limiting portion 124, the second limiting portion 124 is at least one first protruding portion provided on the outer side of the floating member 123, and the first limiting portion 121 is at least one first concave portion provided in the joint installation cavity 122. The first concave portion and the first protruding portion are matched, and the radial dimension of the first concave portion is larger than the radial dimension of the first protruding portion to form the floating space of the floating member 123.

[0090] Specifically, in this embodiment, the first protruding portion can be an annular protruding structure, and correspondingly, the first concave portion can be an annular groove structure. After the first protruding portion is inserted into the second concave portion, the first protruding portion and the first concave portion are in clearance fit in the axial direction to prevent the floating member 123 from being pressed against. The dimensional difference between the first protruding portion and the first concave portion in the radial direction will determine the radial floating amount of the floating member 123 in the joint installation cavity 122.

[0091] It can be understood that, in addition to being set as an annular protruding structure, the first protruding portion can also be set as a plurality of protruding structures spaced circumferentially along the floating member 123. Correspondingly, the first concave portion can also be set as a groove structure spaced circumferentially along the joint installation cavity 122.

[0092] In addition, in another implementation manner of the first limiting portion 121 and the second limiting portion 124, the second limiting portion 124 is at least one second concave portion provided on the outer side of the floating member 123, and the first limiting portion 121 is at least one second protruding portion provided in the joint installation cavity 122. The second concave portion and the second protruding portion are matched, and the radial dimension of the second concave portion is smaller than the radial dimension of the first protruding portion.

[0093] In this embodiment, the matching relationship between the second concave portion and the second protruding portion is the same as the matching relationship between the first concave portion and the first protruding portion in the above implementation manner. The difference between the two implementation manners is that the positions of the concave portion and the protruding portion are swapped, so this embodiment will not be elaborated here.

[0094] The specific shape and size of the joint installation cavity 122 can be set according to the floating member 123. For example, the joint installation cavity 122 can be set to be circular or square, and the corresponding floating member 123 is also set to be circular or square. For the convenience of the floating of the floating member 123, in this embodiment, the joint installation cavity 122 is set as a circular cavity, and the floating member 123 is set as a cylinder.

[0095] To ensure the gas supply, the first pneumatic joint 12 includes a quick-change air nozzle 125, and the second pneumatic joint 301 includes a plurality of quick-insertion holes 3010. When the first pneumatic joint 12 includes a plurality of quick-change air nozzles 125, there are at least two implementation manners for the joint installation cavity 122 of the joint housing 120 and the floating member 123.

[0096] One implementation manner is, as Figure 8 and Figure 9 shown, a plurality of joint installation cavities 122 are provided in the joint housing 120, and the floating members 123 are provided as a plurality and are arranged one by one in the joint installation cavities 122. Specifically, a plurality of joint installation cavities 122 are provided in the joint housing 120, one floating member 123 is installed in each joint installation cavity 122, an access port is provided in each floating member 123, and a quick-change air nozzle 125 is installed.

[0097] Another implementation manner is, as Figure 10 and Figure 11 shown, a relatively large joint installation cavity 122 is provided in the joint housing 120, and a plurality of access ports are provided on the floating member 123 installed in the joint installation cavity 122, so that a plurality of quick-change air nozzles 125 can be installed on the same floating member 123. Compared with the previous implementation manner, a plurality of quick-change air nozzles 125 can float integrally, and fewer processing parts are required, and the use cost is lower.

[0098] According to another aspect of the present application, there is provided a pneumatic quick-change joint assembly, including a first joint and a second joint. The first joint includes the above-mentioned floating pneumatic quick-change joint, and a quick-insertion hole is provided in the second joint; the first joint is used to be fixed to a fixing component, and the second joint is used to be fixed to a conversion component; or, the first joint is used to be fixed to the conversion component, and the second joint is used to be fixed to the fixing component.

[0099] In this embodiment, the fixing component is a fixing frame 1, and the conversion component is a magazine panel 3.

[0100] According to another aspect of the present application, there is provided a material bin, including the above-mentioned floating pneumatic quick-change joint. The material bin in this embodiment is the quick-change cardboard bin in the above-mentioned embodiment.

[0101] As Figures 12 to 14As shown, in a detachable connection method between the conveyor 5 and the conveying channel 4 and a fastening method of the fastening structure 6, a first connection portion 13 is provided on the conveyor 5, and a second connection portion 14 is provided in the conveying channel 4. The first connection portion 13 and the second connection portion 14 are detachably inserted and matched with each other.

[0102] The fastening structure 6 includes a pressing portion 601. The pressing portion 601 is configured to be able to apply a pressing force towards the second connection portion 14 to the first connection portion 13, so that the first connection portion 13 can be pressed and fixed on the second connection portion 14.

[0103] Specifically, in this embodiment, when the conveyor 5 is installed on the conveying channel 4, the connection of the third pneumatic joint 8 and the fourth pneumatic joint 20 is completed synchronously. The connection between the conveyor 5 and the conveying channel 4 is realized through the first connection portion 13 and the second connection portion 14. The insertion and matching of the first connection portion 13 and the second connection portion 14 makes the installation and disassembly of the conveyor 5 relatively convenient. To achieve the insertion and matching, one of the first connection portion 13 and the second connection portion 14 is set as a protruding structure, and the other is set as a groove structure. According to different installation methods, the protruding structure has different positions, and the groove structure has different opening directions. When using vertical insertion and matching, the opening direction of the groove structure is vertical. When using horizontal insertion and matching, the opening direction of the groove structure is horizontal.

[0104] On the basis of the insertion and matching of the first connection portion 13 and the second connection portion 14, to further improve the connection stability, the fastening structure 6 in this embodiment uses a method of applying a pressing force to the first connection portion 13 to enable the first connection portion 13 and the second connection portion 14 to be tightly connected. Specifically, the fastening structure 6 in this embodiment includes a pressing portion 601. The pressing portion 601 can be operatively applied with a pressing force towards the second connection portion 14 to the first connection portion 13, so that the first connection portion 13 can be pressed and fixed on the second connection portion 14.

[0105] In this embodiment, the fastening structure 6 as a structure capable of applying a pressing force can adopt fastening screws, pressing pliers or elastic clamping members, etc. The specific structure of the fastening structure 6 in this embodiment is not limited.

[0106] A fourth pneumatic joint 20 is provided on the first connection portion 13, and a third pneumatic joint 8 is provided on the second connection portion 14. The fourth pneumatic joint 20 and the third pneumatic joint 8 are detachably inserted and matched with each other; the fourth pneumatic joint 20 is communicated with the internal air supply pipeline in the conveyor 5, and the third pneumatic joint 8 is communicated with the air duct in the bin panel 3. The fourth pneumatic joint 20 and the third pneumatic joint 8 are arranged along the insertion direction of the first connection portion 13 and the second connection portion 14.

[0107] In this embodiment, when the third pneumatic joint 8 and the fourth pneumatic joint 20 are in the same connection direction as the insertion direction of the first connection part 13 and the second connection part 14, and the fourth pneumatic joint 20 is arranged on the first connection part 13, the pressing force applied by the pressing part 601 to the first connection part 13 also acts on the fourth pneumatic joint 20 and the third pneumatic joint 8 synchronously. Under the action of the air pressure after ventilation, the first connection part and the second connection part can still maintain a tight connection through this pressing force.

[0108] In an embodiment of the connection between the first connection part 13 and the second connection part 14, as Figure 12 shown, the first connection part 13 and the second connection part 14 are arranged to be detachably inserted and matched in the horizontal direction. In this embodiment, a first connection protrusion 130 is provided on the first connection part 13, and a first connection groove 140 is provided on the second connection part 14. The first connection protrusion 130 and the first connection groove 140 can be engaged with each other.

[0109] Specifically, in this embodiment, the first connection groove 140 has an opening in the horizontal direction, and the first connection protrusion 130 corresponds to the first connection groove 140. As Figure 12 shown, when installing the conveyor 5, the conveyor 5 can be first loaded into the conveying channel 4 and the first connection protrusion 130 is located in front of the first connection groove 140, and then the conveyor 5 is pushed horizontally so that the first connection protrusion 130 is snapped into the first connection groove 140 and engaged with each other (as Figure 13 shown), and then the fastening structure 6 can be operated to tightly connect the first connection protrusion 130 and the first connection groove 140 (as Figure 14 shown).

[0110] During this process, to synchronously complete the connection of the third pneumatic joint 8 and the fourth pneumatic joint 20, the fourth pneumatic joint 20 and the third pneumatic joint 8 are arranged along the insertion direction of the first connection part 13 and the second connection part 14. Further, as Figure 12 shown, the fourth pneumatic joint 20 can be arranged at the end of the first connection protrusion 130, and the third pneumatic joint 8 can be arranged in the first connection groove 140. Of course, it can be understood that the fourth pneumatic joint 20 can also be arranged at other positions of the first connection part 13, and the third pneumatic joint 8 can also be arranged at other positions of the second connection part 14. For the convenience of installation, the inner bottom surface of the first connection groove 140 is in close fit with the lower bottom surface of the first connection protrusion 130, and there is a certain gap between the upper top surface of the first connection groove 140 and the upper top surface of the first connection protrusion 130.

[0111] To enable the first connection protrusion 130 and the first connection groove 140 to be accurately connected, as Figure 12As shown, in this embodiment, a support portion 141 protruding horizontally from the first connection groove 140 is provided at the lower end of the second connection portion 14, and the upper surface of the support portion 141 is flush with the inner bottom surface of the first connection groove 140.

[0112] During installation, the conveyor 5 can be first vertically inserted into the conveying channel 4 and the lower end of the first connection portion 13 is abutted against the support portion 141. At this time, the first connection protrusion 130 on the first connection portion 13 and the first connection groove 140 on the second connection portion 14 are opposite to each other in the horizontal direction. Then, by horizontally pushing the conveyor 5, the first connection protrusion 130 and the first connection groove 140 can be docked.

[0113] It can be understood that the first connection portion 13 can also be set as a groove structure, and the second connection portion 14 can also be set as a protrusion structure. The cooperation between the two is the same as that of the first connection protrusion 130 and the first connection groove 140 in the above embodiment, and will not be elaborated here.

[0114] In this embodiment, as Figure 12 shown, due to the setting of the first connection groove 140, a protrusion structure is further provided on the second connection portion 14, and this protrusion structure is located above the first connection groove 140. To further improve the connection tightness between the first connection portion 13 and the second connection portion 14, a groove structure corresponding to this protrusion structure can be provided on the first connection portion 13. This groove structure can be located above the first connection protrusion 130, and the protrusion structure and the groove structure are also in clearance fit on the upper top surface.

[0115] Since the conveyor 5 has a certain length, there is a relatively long lever arm between the end of the conveyor 5 and the first connection portion 13. Therefore, to further improve the structural stability of the conveyor 5 after installation, as Figure 12 shown, in this embodiment, a second connection groove 142 is provided on the second connection portion 14, a second connection protrusion 16 is provided on the conveyor 5, the second connection groove 142 includes a vertical opening 1420 and a horizontal groove body 1421, and the second connection protrusion 16 is configured to be able to vertically pass through the vertical opening 1420 and horizontally snap into the horizontal groove body 1421.

[0116] Specifically, in this embodiment, the second connection groove 142 and the first connection groove 140 are horizontally distributed on the connection portion. During installation, as Figure 12As shown, the conveyor 5 is loaded into the conveying channel 4 vertically. At the same time, the lower end of the first connecting portion 13 abuts against the supporting portion 141, and the second connecting protrusion 16 is inserted into the second connecting groove 142 through the vertical opening 1420. At this time, the first connecting protrusion 130 and the first connecting groove 140 are horizontally opposite, and the second connecting protrusion 16 and the horizontal groove body 1421 are horizontally opposite. Then, the conveyor 5 can be pushed to make the first connecting protrusion 130 snap into the first connecting groove 140 and the second connecting protrusion 16 snap into the horizontal groove body 1421 (as Figure 13 shown). In this embodiment, through the engagement of the first connecting protrusion 130 and the first connecting groove 140, and the engagement of the second connecting protrusion 16 and the horizontal groove body 1421, the downward force on the conveyor 5 can be better resisted, thereby further improving the structural stability of the conveyor 5 after installation.

[0117] To facilitate the insertion of the second connecting protrusion 16 into the vertical opening 1420, the vertical opening 1420 in this embodiment can be set as a flared structure opening upward.

[0118] In an implementation manner of the fastening structure 6, the fastening structure 6 is provided on the silo panel 3. To facilitate the operation of the pressing portion 601, as Figure 12 shown, the fastening structure 6 in this embodiment further includes an operating portion 602. The operating portion 602 is connected to the pressing portion 601 and is used to operate the pressing portion 601 to apply pressure to the first connecting portion 13 in the insertion direction of the first connecting portion 13, and is used to operate the pressing portion 601 to disengage from the first connecting portion 13.

[0119] Specifically, it should be noted that the operating portion 602 and the pressing portion 601 are a follow-up structure. By controlling the movement of the operating portion 602, the movement of the pressing portion 601 is driven to apply pressure to the first connecting portion 13. While enabling the first connecting portion 13 to be tightly connected to the second connecting portion 14, the gas pressure at the docking position of the fourth pneumatic joint 20 and the third pneumatic joint 8 during the gas flow can be resisted.

[0120] Furthermore, the operating portion 602 is arranged to be able to operate the pressing portion 601 to rotate and press on the first connecting portion 13 in a rotational manner, and to be able to operate the pressing portion 601 to rotate and disengage from the first connecting portion 13 in a rotational manner. In this embodiment, the fastening structure 6 is set as a pressing clamp, the operating portion 602 is the operating handle of the pressing clamp, and the pressing portion 601 is the pressing block of the pressing clamp. The pressing block can be pressed on the first connecting portion 13 by controlling the rotation of the operating handle, or the pressing block can be disengaged from the first connecting portion 13 by controlling the rotation of the operating handle.

[0121] In one arrangement of the conveyor 5, a plurality of conveyors 5 are provided, a plurality of conveying channels 4 are provided on the silo panel 3, a first connecting portion 13 is provided on each conveyor 5, a second connecting portion 14 is provided in each conveying channel 4, a plurality of fastening structures 6 are provided, and at least one fastening structure 6 among the plurality of fastening structures 6 corresponds to at least one connecting portion among the plurality of first connecting portions 13.

[0122] As for the conveyor 5, the related art mainly adopts a belt conveyor 5, which adopts a drive device (such as a cylinder) installed outside the conveyor belt. Taking the cylinder as an example, the conveyor belt 18 is driven to move by the telescopic movement of the cylinder during the driving process. However, such an external form of the drive device makes the drive device exposed to the outside, which is easy to produce a sanitary dead corner, resulting in dust accumulation.

[0123] To this end, the present embodiment further improves the structure of the conveyor 5:

[0124] Specifically, Figures 15 to 17 As shown, the conveyor 5 includes: a frame 51, in which a hollow installation chamber 52 is arranged; at least two conveying wheels 17 are provided and are rotatably arranged at the first end and the second end of the frame 51 respectively; a conveying belt 18 is sleeved on the conveying wheels 17 at both ends, and the conveying belt 18 is driven by the rotation of the conveying wheels 17 to move; a driving mechanism 19 is built into the installation chamber 52, and the driving mechanism 19 is transmission-connected to at least one of the conveying wheels 17 for driving the conveying wheel 17 to rotate.

[0125] In this embodiment, the conveyor 5 mainly includes a frame 51, a conveying wheel 17, a conveying belt 18 and a driving mechanism 19, wherein the conveying wheels 17 are located at both ends of the frame 51 and can rotate around a fixed axis, and the conveying belt 18 is sleeved on the conveying wheels 17 at both ends. When the conveying wheel 17 at one end rotates, the conveying belt 18 can be driven to move and the conveying wheel 17 at the other end can be rotated. The driving mechanism 19 can be connected to the conveying wheel 17 at one end to drive the conveying wheel 17 to rotate. In order to prevent the driving mechanism 19 from being exposed to the frame 51, an installation chamber 52 is provided in the frame 51 in this embodiment, and the driving mechanism 19 can be built into the installation chamber 52.

[0126] In this embodiment, by providing an installation chamber 52 in the frame 51, the drive mechanism 19 is arranged by using the installation chamber 52, so that the drive mechanism 19 can be hidden in the frame 51 instead of being exposed from the frame 51, thereby reducing sanitary dead corners and reducing the amount of dust accumulated on the drive mechanism 19. In addition, after the drive mechanism 19 is built into the installation chamber 52, the integrity of the conveyor 5 is improved, and when the conveyor 5 is installed, only the external structure of the frame 51 needs to be considered, and the aesthetics of the conveyor 5 is also improved.

[0127] In one embodiment of the rack 51, asFigure 15 As shown, the frame 51 includes a first side plate body 511 and a second side plate body 513. The first side plate body 511 and the second side plate body 513 are arranged opposite to each other and can be fixedly connected by a belt support plate and a number of connecting columns. The installation chamber 52 is located in the area between the first side plate body 511 and the second side plate body 513.

[0128] On the basis of the above embodiment, the frame 51 further includes a first end plate body 510 and a second end plate body 512. The first end plate body 510 is located between the first ends of the first side plate body 511 and the second side plate body 513, and the second end plate body 512 is located between the second ends of the first side plate body 510 and the second side plate body 511.

[0129] In this embodiment, multiple parts of a plate can be bent to respectively form the first side plate body 511, the second side plate body 513, the first end plate body 510 and the second end plate body 512, or the first side plate body 511, the second side plate body 513, the first end plate body 510 and the second end plate body 512 are all separate plates and are assembled to form the frame 51 by splicing with each other. Or some of the first side plate body 511, the second side plate body 513, the first end plate body 510 and the second end plate body 512 are formed by bending a plate, and the remaining plate bodies are separate spliced plates.

[0130] In this embodiment, the first side plate body 511, the second side plate body 513, the first end plate body 510 and the second end plate body 512 together form a frame 51 that is generally in a frame shape. The driving mechanism 19 and the conveying wheel 17 are both arranged in the installation chamber 52 of the frame 51, and the conveying wheel 17 can be hinged to the first side plate body 511 and the second side plate body 513 through a rotating shaft.

[0131] In one embodiment of the driving mechanism 19, as Figure 16 shown, the driving mechanism 19 includes a reciprocating motion mechanism 191 and a one-way rotation mechanism 192;

[0132] The one-way rotation mechanism 192 includes a first rotating part 1921 and a second rotating part 1920. In the first rotation direction, the first rotating part 1921 can drive the second rotating part 1920 to rotate synchronously. In the second rotation direction, the first rotating part 1921 can rotate independently relative to the second rotating part 1920, and the second rotating part 1920 is fixedly connected to the corresponding conveying wheel 17;

[0133] The output end of the reciprocating motion mechanism 191 is in transmission connection with the first rotating part 1921 for driving the first rotating part 1921 to rotate in the first rotation direction and the second rotation direction.

[0134] Specifically, in this embodiment, the conveying of the cardboard by the conveyor 5 is achieved by the intermittent movement of the conveyor belt 18, that is, by the intermittent rotation of the conveying wheel 17 in a single direction. The reciprocating mechanism 191 in the driving mechanism 19 can output reciprocating motion, so after the reciprocating mechanism 191 is directly connected to the conveying wheel 17, it will drive the conveying wheel 17 to rotate forward and reverse, so that the cardboard cannot be normally conveyed. For this reason, the driving mechanism 19 in this embodiment also includes a unidirectional rotation mechanism 192. After the unidirectional rotation mechanism 192 is connected to the reciprocating mechanism 191 and the conveying wheel 17, only the motion in one direction output by the reciprocating mechanism 191 acts on the conveying wheel 17, and the motion in the other direction output by the reciprocating mechanism 191 does not act on the conveying wheel 17, so that the reciprocating mechanism 191 can drive the conveying wheel 17 to rotate intermittently in one direction during the reciprocating motion.

[0135] Furthermore, it should be noted that, in order to achieve the above functions, the one-way rotating mechanism 192 in this embodiment includes a first rotating portion 1921 and a second rotating portion 1920. The second rotating portion 1920 is fixedly connected to the corresponding conveying wheel 17. In the first rotation direction, the first rotating portion 1921 can drive the second rotating portion 1920 to rotate synchronously, thereby driving the conveying wheel 17 to rotate, thereby realizing cardboard conveying.

[0136] In the second rotation direction, the first rotating part 1921 can rotate independently relative to the second rotating part 1920, so that the conveying wheel 17 remains stationary. The output end of the reciprocating mechanism 191 is connected to the first rotating part 1921 for driving the first rotating part 1921 to rotate in the first rotation direction and the second rotation direction.

[0137] In this embodiment, the first rotation direction can be clockwise or counterclockwise, and the second rotation direction can be counterclockwise or clockwise. The specific direction is not limited in this embodiment and can be determined according to the installation method of the unidirectional rotation mechanism 192.

[0138] In one embodiment, when conveying cardboard, the reciprocating motion mechanism 191 outputs the motion in the first direction, and at this time, the first rotating part 1921 can be driven to rotate in the first rotation direction, and the second rotating part 1920 and the conveying wheel 17 can be driven to rotate synchronously, so as to realize the conveying of cardboard. When the reciprocating motion mechanism 191 ends the motion stroke in this direction and needs to output the motion in the opposite direction, the first rotating part 1921 can be driven to rotate in the second rotation direction, and at this time, the second rotating part 1920 is not affected by the first rotating part 1921 and remains stopped, so that the conveying wheel 17 and the conveying belt 18 remain stopped, until the reciprocating motion mechanism 191 ends the motion in the opposite direction and continues to output the motion in the first direction, and then the conveying of cardboard continues.

[0139] In an embodiment of the one-way rotation mechanism 192, the one-way rotation mechanism 192 is arranged as a ratchet assembly, which includes an inner ring with ratchet teeth and an outer ring with sliding pieces. In the direction of the ratchet teeth, the rotation of the inner ring will drive the rotation of the outer ring, and in the direction opposite to the ratchet teeth, the rotation of the inner ring has no effect on the outer ring.

[0140] In another embodiment of the one-way rotation mechanism 192, the one-way rotation mechanism 192 includes a one-way bearing assembly. The first rotating part 1921 includes the bearing outer ring of the one-way bearing assembly, and the second rotating part 1920 includes the bearing inner ring of the one-way bearing assembly.

[0141] Based on the above embodiment, the one-way bearing assembly includes a one-way bearing and a bearing seat. The bearing outer ring of the one-way bearing is sleeved and fixed in the bearing seat. The bearing outer ring and the bearing seat form the first rotating part 1921. The bearing inner ring of the one-way bearing is fixedly connected to the conveying wheel 17 through a rotating shaft, and the bearing seat is in transmission connection with the output end of the reciprocating motion mechanism 191.

[0142] Specifically, in this embodiment, the bearing seat can be generally in a ring structure. The bearing seat is sleeved and fixed on the bearing outer ring of the one-way bearing. The bearing inner ring of the one-way bearing can be fixedly connected to the conveying wheel 17 through a transmission shaft. After the output end of the reciprocating motion mechanism 191 is in transmission connection with the bearing seat, it can drive the bearing seat and the bearing outer ring to rotate.

[0143] In an embodiment of the reciprocating motion mechanism 191, as Figure 16 shown, the reciprocating motion mechanism 191 includes a first linear motion component 1910. The driving end of the first linear motion component 1910 is hinged to the frame 51, and the output end of the first linear motion component 1910 is hinged to the bearing seat.

[0144] Specifically, it should be noted that in this embodiment, the first linear motion component 1910 is a component capable of outputting reciprocating linear motion, and can adopt a linear motion cylinder, a linear motion motor, a lead screw transmission mechanism, etc. To convert the linear motion output by the first linear motion component 1910 into a driving force for driving the rotation of the bearing outer ring, in this embodiment, the driving end of the first linear motion component 1910 is hinged to the frame 51, and at the same time, the output end of the first linear motion component 1910 is hinged to the bearing seat. When the first linear motion component 1910 outputs linear motion, it will push the bearing seat to rotate, and at the same time, the first linear motion component 1910 also rotates around the hinge point, thereby driving the rotation of the bearing outer ring.

[0145] In a specific application, when the first linear motion component 1910 outputs a linear motion extending outwards, the driving bearing housing and the outer bearing ring rotate counterclockwise. At this time, the inner bearing ring remains stationary, causing the conveying wheel 17 and the conveyor belt 18 to remain stationary. When the first linear motion component 1910 outputs a linear motion retracting inwards, the driving bearing housing and the outer bearing ring rotate clockwise. At this time, the inner bearing ring rotates synchronously, causing the conveying wheel 17 and the conveyor belt 18 to move synchronously.

[0146] In another embodiment of the reciprocating motion mechanism 191, as Figure 17 shown, the reciprocating motion mechanism 191 includes a second linear motion component 1912, a transmission wheel 1914, a transmission belt 1915, and a belt clip 1913; at least two transmission wheels 1914 are provided and rotatable, and the transmission belt 1915 is sleeved on the transmission wheels 1914.

[0147] Specifically, it should be noted that in this embodiment, the transmission wheel 1914 and the transmission belt 1915 form a set of belt conveying components. When the upper part or the lower part of the transmission belt 1915 is driven to move linearly, it can drive the transmission wheels 1914 at both ends to rotate. The rotation direction of the transmission wheel 1914 is determined by the linear motion direction of the transmission belt 1915. In this embodiment, the linear motion of the transmission belt 1915 is realized by being driven by the second linear motion component 1912. The second linear motion component 1912 can also adopt devices such as a linear motion cylinder, a linear motion motor, or a lead screw transmission mechanism that can output linear motion. To enable the second linear motion component 1912 to drive the transmission belt 1915 to move, a belt clip 1913 is fixed on the transmission belt 1915 in this embodiment, and the output end of the second linear motion component 1912 is fixedly connected to the belt clip 1913. To enable the rotation of the transmission wheel 1914 to act on the conveying wheel 17, in this embodiment, one transmission wheel 1914 is sleeved and fixed to the outer bearing ring of the one-way bearing assembly.

[0148] In a specific application, when the second linear motion component 1912 outputs a linear motion extending outwards, the transmission belt 1915 is driven to move forward through the belt clip 1913 while driving the transmission wheel 1914 to rotate clockwise. Under the action of the transmission wheel 1914, the outer bearing ring rotates clockwise synchronously, driving the inner bearing ring and the conveying wheel 17 to rotate clockwise, thereby driving the conveyor belt 18 to move. When the second linear motion component 1912 outputs a linear motion retracting inwards, the transmission belt 1915 is driven to move backward through the belt clip 1913 while driving the transmission wheel 1914 to rotate counterclockwise. Under the action of the transmission wheel 1914, the outer bearing ring rotates counterclockwise synchronously. At this time, the inner bearing ring and the conveying wheel 17 remain stationary, that is, the conveyor belt 18 remains stationary.

[0149] In one embodiment of the conveying wheel 17, as Figure 16As shown, the conveying wheel 17 fixedly connected to the bearing inner ring of the one-way bearing assembly includes a first wheel body 170 and a second wheel body 171 arranged oppositely. The one-way bearing assembly is disposed between the first wheel body 170 and the second wheel body 171, and the first wheel body 170, the second wheel body 171, and the bearing inner ring of the one-way bearing assembly are fixedly connected.

[0150] Specifically, it should be noted that in this embodiment, by setting the first wheel body 170 and the second wheel body 171, the contact area between the conveying wheel 17 and the conveyor belt 18 can be increased. And after the one-way bearing assembly is disposed between the first wheel body 170 and the second wheel body 171, the driving force of the one-way bearing assembly can act evenly on the first wheel body 170 and the second wheel body 171, improving the movement stability of the conveying wheel 17.

[0151] In an embodiment of the first linear motion assembly 1910 and the second linear motion assembly 1912, the first linear motion assembly 1910 and the second linear motion assembly 1912 include linear motion cylinders;

[0152] As Figure 15 shown, an air pipe is further disposed in the installation chamber 52, and a connector is disposed on the frame 51. The first end of the air pipe is connected to the connector, and the second end of the air pipe is connected to the linear motion cylinder.

[0153] Specifically, in this embodiment, since it is necessary to supply air to the linear motion cylinder through the air pipe, in order to reduce the sanitary dead angle of the air pipe, the air pipe is also arranged in the installation chamber in this embodiment. On this basis, in order to facilitate the connection between the external air circuit and the air pipe, a connector, that is, the fourth pneumatic connector 20, is disposed on the frame 51 in this embodiment.

[0154] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
