[0006] One is that the gas path is changed along with the changing parts through quick plug-in and pull-out. This requires high processing accuracy of the quick plug and quick plug interface on the changing side and the fixed side, and the installation accuracy and difficulty of the parts are also high.

DETAILED DESCRIPTION

[0046] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0047] To solve relevant technical problems, such as Figures 1 to 5 As shown, an embodiment of the utility model provides a quick-change cardboard silo, comprising: a fixed frame 1, on which a first pneumatic joint 12 is arranged; a silo panel 3, the bottom end of the silo panel 3 is detachably hinged to the fixed frame 1, and a second pneumatic joint 301 is arranged on the silo panel 3, the first pneumatic joint 12 and / or the second pneumatic joint 301 is arranged to float in the rotation radial direction of the silo panel 3, and the second pneumatic joint 301 is plugged and matched with the first pneumatic joint 12; a conveying channel 4 is arranged on the silo panel 3; a locking member 2, used to lock and fix the silo panel 3 on the fixed frame 1 and release the silo panel 3; a conveyor 5, which is detachably arranged in the conveying channel 4; a fastening structure 6, used to fix the conveyor 5 in the conveying channel 4 and release the conveyor 5.

[0048] In this embodiment, the cardboard silo mainly includes a fixed frame 1, a silo panel 3, a conveyor 5, a locking member 2 and a fastening structure 6, wherein the fixed frame 1 is used as a frame structure in the cardboard silo, and the fixed frame 1 can be placed on the loading station of the cardboard, and serves as the installation basis of other components such as the silo panel 3. Since the cardboard needs to be loaded through the fixed frame 1, a channel with a certain area is opened on the fixed frame 1, and the channel can be set to a channel structure 101 similar to and corresponding to the conveying channel 4 on the silo panel 3, or as shown in FIG. Figure 2 The hole structure 101 shown is configured to be much larger than the conveying channel 4 and corresponds to the silo panel 3 .

[0049] The silo panel 3 is a roughly plate-like structure, which can be mounted on the fixed frame 1. In order to realize the loading of paperboard, a conveying channel 4 is provided on the silo panel 3, and the conveying channel 4 corresponds to the channel 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 paperboard to be loaded, and this embodiment does not limit it here. The number of conveying channels 4 can be set to one or more according to different production processes, and this embodiment does not limit it here.

[0050] In this embodiment, the silo panel 3 is connected to the fixed frame 1 in a hinged manner. After the silo panel 3 is installed to the fixed frame 1, it can be rotated to the installation position. Similarly, the silo panel 3 can be disassembled by rotating it to the disassembly position. Compared with the installation method of the silo panel 3 being inserted as a whole in the related art, the silo panel 3 is installed in a hinged manner. There is no need to align multiple positions during installation, and the device for hingedly connecting 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.

[0051] In a hinged embodiment of the silo panel 3 and the fixed frame 1, as Figure 4 As shown, a horizontal axis 10 is provided on the fixed frame 1, and a slot 11 capable of engaging 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 tilted into the fixed frame 1 and the slot 11 can be engaged with the horizontal axis 10, and then the silo panel 3 can be rotated to the installation position with the axis of the horizontal axis 10 as the center. During disassembly, the silo panel 3 is rotated in the opposite direction to the disassembly position and then pulled out to disengage the slot 11 from the horizontal axis 10. In this embodiment, the horizontal axis 10 can be a long axis structure or a short axis distributed on both sides of the fixed frame 1.

[0052] It is understandable that the transverse axis 10 can also be set on the silo panel 3, and the card slot 11 can be set on the fixed frame 1, and the two can maintain a hinged connection state after being carded.

[0053] In another hinged embodiment of the silo panel 3 and the fixed frame 1, a rotatable clip can be provided on the fixed frame 1, and another clip is fixed on the silo panel 3. The silo panel 3 is installed on the fixed frame 1 by snapping the two clips together, and then the silo panel 3 is rotated to drive the clip on the fixed frame 1 to rotate, thereby installing the silo panel 3 to the installation position.

[0054] In addition, it should be noted that the card slot 11 can be a structure arranged at the lower end of the silo panel 3 (such as Figure 4 As shown), it can also be set as a structure on the back of the silo panel 3.

[0055] 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 circular motion of the silo panel 3 is intercepted, the motion trajectory of this section is close to a straight line, and when the motion section of the same length is intercepted, the position farther away from the horizontal axis 10 is closer to a straight line. Since the plug-in matching of the first pneumatic joint 12 and the second pneumatic joint 301 needs to be completed synchronously when installing the silo panel 3, and the disengagement of the first pneumatic joint 12 and the second pneumatic joint 301 needs to be completed synchronously when disassembling. Considering that the connection and disengagement of the first pneumatic joint 12 and the second pneumatic joint 301 are both a section of linear motion, 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, so 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, so that the distance between the two is far enough.

[0056] 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 achieve the synchronous completion of the pneumatic connection during the rotation of the silo panel 3, in this embodiment, at least one of the first pneumatic joint 12 and the second pneumatic joint 301 is set as a floating joint. Specifically, taking the first pneumatic joint 12 as a floating joint as an example, the floating direction of the first pneumatic joint 12 is the radial direction of the rotation circle of the silo panel 3. After the second pneumatic joint 301 contacts the first pneumatic joint 12 with the rotation of the silo panel 3, as the silo panel 3 further rotates, the insertion depth of the first pneumatic joint 12 and the second pneumatic joint 301 gradually increases. In 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.

[0057] like Figure 4aAs 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 plugged into place, L is the rotation trajectory of the second pneumatic joint 301, and the maximum vertical distance from the part between A1 and A2 in L to the line connecting A1 and A2 is the maximum movement amount D of the pneumatic joint, and the floating amount of the first pneumatic joint 12 should be greater than or equal to the maximum movement amount D. When designing a product, the distance from A1 to A2 (i.e., the insertion depth) and the floating amount can be determined first, and then the composite condition R can be inversely calculated, that is, the arrangement position of the first pneumatic joint 12 and the second pneumatic joint 301 can be inversely calculated. When the first pneumatic joint 12 has multiple interfaces in the radial direction, the interface position closest to the rotation center can be used for calculation.

[0058] Since the silo panel 3 and the fixed frame 1 are in a hinged connection, in order to fix the silo panel 3 during use, this is achieved by operating the locking member 2 in this embodiment. Figure 1 and Figure 2 As shown, the locking member 2 is a structure for fixing the silo panel 3 after the silo panel 3 is rotated to the installation position. The locking member 2 can be installed on the fixed frame 1. After the silo panel 3 is rotated to the installation position, the locking member 2 can be operated to fix the silo panel 3.

[0059] In one embodiment of the locking member 2, Figure 2 As shown, the locking member 2 can be a structure hinged on the fixed frame 1. After the silo panel 3 is rotated to the installation position, the locking member 2 can be rotated to abut against the outer side of the silo panel 3, thereby fixing the silo panel 3.

[0060] In another embodiment of the locking member 2 , the locking member 2 may be a latch-like structure, which can be inserted into the silo panel 3 and the fixed frame 1 from the side at the same time, thereby fixing the silo panel 3 .

[0061] In another embodiment of the locking member 2, the locking member 2 may be a clamp structure, which is fixed on the fixed frame 1, and the silo panel 3 is compressed by rotating the clamp.

[0062] After the silo panel 3 is installed, the conveyor 5 can be installed in the conveying channel 4 of the silo panel 3. The conveyor 5 can convey the cardboard by driving the conveyor belt 18 to circulate. Figure 1 and Figure 2 As shown, in this embodiment, the conveyor 5 is installed at the bottom end of the conveying channel 4, and the cardboard to be loaded is placed in the conveying channel 4 and located on the conveyor 5, and the conveyor 5 completes the conveying of the cardboard. A mounting groove matching the conveyor 5 can be formed at the bottom end of the conveying channel 4, and the conveyor 5 can be installed in the mounting groove.

[0063] In order to enable the conveyor 5 to be fixed in the conveying passage 4, this is achieved by operating the fastening structure 6 in this embodiment. 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 fix the conveyor 5 by applying pressure to the conveyor 5 against the conveying passage 4. In this embodiment, the fastening structure 6 can be a pressure clamp, a fastening screw, etc.

[0064] This embodiment achieves the goal that when changing the type, the bottom end of the silo panel 3 can be firstly connected with the fixed frame 1 obliquely so that the silo panel 3 and the fixed frame 1 are in a hinged state, and then the silo panel 3 is rotated to make it close to the fixed frame 1 and rotated to the installation position. In this process, the first pneumatic joint 12 or the second pneumatic joint 301 that can float along the rotation radial direction can be synchronously connected, that is, the gas path connection of the silo panel 3 and the fixed frame 1 is synchronously completed during the installation of the silo panel 3. Then the locking member 2 can be operated to fix the silo panel 3, and then the conveyor 5 can be installed in the conveying channel 4 of the silo panel 3, and then the fastening structure 6 is operated to complete the purpose of fixing the conveyor 5, thereby achieving the technical effect that the silo panel 3 and the conveyor 5 can be quickly changed during the silo change, and the silo panel 3 can be easily aligned when changing the type, and the gas path connection can be synchronously completed, thereby solving the problem in the related art that the silo panel 3 is difficult to connect in the overall silo change environment, and the gas path required by the silo after the change needs to be connected separately, resulting in inconvenience in the change operation.

[0065] In the present invention, the conveyor 5 uses gas as a power source, and the gas supply to the conveyor 5 is achieved through an external gas supply device and a corresponding gas channel. Since the conveyor 5 and the silo panel 3 in the present invention are both replaceable structures, the external gas supply device is preferably connected to the fixed frame 1, so a gas channel that meets the fixed frame 1, the silo panel 3 and the conveyor 5 needs to be established.

[0066] In this embodiment, if Figure 2 As shown, a first pneumatic joint 12 is provided on the fixed frame 1, and an airway, a second pneumatic joint 301 and a third pneumatic joint 8 communicating with the airway are provided on the silo panel 3. Fig.12 As shown, a fourth pneumatic connector 20 is provided on the conveyor 5, and the fourth pneumatic connector 20 is connected to the pneumatic equipment in the conveyor 5. In this embodiment, the gas channel is established by connecting the first pneumatic connector 12 and the second pneumatic connector 301, and the third pneumatic connector 8 and the fourth pneumatic connector 20.

[0067] As for the connection between the first pneumatic connector 12 and the second pneumatic connector 301, the present embodiment adopts a plug-in method. Since the first pneumatic connector 12 is directly arranged on the fixed frame 1, and the second pneumatic connector 301 is directly arranged on the silo panel 3. Therefore, when the silo panel 3 is rotated to the installation position, the first pneumatic connector 12 and the second pneumatic connector 301 can be connected synchronously. Similarly, the reverse rotation of the silo panel 3 during disassembly can also disengage the first pneumatic connector 12 and the second pneumatic connector 301. In other words, the connection of the first pneumatic connector 12 and the second pneumatic connector can be completed synchronously during the installation process of the silo panel 3, and the disengagement of the first pneumatic connector 12 and the second pneumatic connector 301 can be completed synchronously during the disassembly process of the silo panel 3.

[0068] As for the connection between the third pneumatic joint 8 and the fourth pneumatic joint 20, the present embodiment also adopts the plug-in method. Since the third pneumatic joint 8 is directly arranged on the silo panel 3, and the fourth pneumatic joint 20 is directly arranged on the conveyor 5. Therefore, when the conveyor 5 is installed in the conveying channel 4 on the silo panel 3, the third pneumatic joint 8 and the fourth pneumatic joint 20 can be connected synchronously. Similarly, when the conveyor 5 is disassembled, the third pneumatic joint 8 and the fourth pneumatic joint 20 can also be disengaged synchronously. In other words, the connection of the third pneumatic joint 8 and the fourth pneumatic joint can be completed synchronously during the installation process of the conveyor 5, and the disengagement of the third pneumatic joint 8 and the fourth pneumatic joint 20 can be completed synchronously during the disassembly process of the conveyor 5.

[0069] The utility model uses the quick-change cardboard silo to achieve that before changing the type, 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, and then the locking member 2 can be operated to release the fixation of the silo panel 3, and then the silo panel 3 can be rotated. During the rotation process, the first pneumatic joint 12 and the second pneumatic joint 301 are automatically disengaged, and the silo panel 3 can be removed from the fixed frame 1 after rotating to the set position. When changing the type, the silo panel 3 can be hinged to the fixed frame 1 first, and the silo panel 3 can be rotated to complete the installation of the silo panel 3 and the connection of the first pneumatic joint 12 and the second pneumatic joint 301, and then the locking member can be operated. 2 fixes the silo panel 3, and then the conveyor 5 can be installed in the conveying channel 4. The conveyor 5 is fixed in the conveying channel 4 by operating the fastening structure 6 and the connection of the third pneumatic joint 8 and the fourth pneumatic joint 20 is simultaneously completed, thereby realizing the rapid replacement of the silo panel 3 and the conveyor 5 during the silo replacement process, and the gas path of the silo can be disconnected and connected with the removal and installation of the silo panel 3 and the conveyor 5 during the replacement process, that is, there is no need to make additional connections to the gas path during the replacement process, making the replacement operation more convenient. This solves the problem in the related art that in the overall replacement silo replacement environment, the gas path required by the silo after the replacement needs to be connected separately, resulting in inconvenience in the replacement operation.

[0070] In order to realize the function of conveying cardboard, the conveyor 5 needs to have a certain length. In order to improve the running stability of the conveyor 5, the conveyor 5 needs to be supported by auxiliary means. Figure 1 , Figure 2 and Figure 5 As shown, the quick-change paperboard bin in this embodiment also includes:

[0071] The support arm assembly 7 includes 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 is abutted against the lower end of the conveyor 5 to support the conveyor 5.

[0072] In this embodiment, since the conveyor 5 is a replaceable structure, the corresponding support arm assembly 7 also needs to be configured to be a structure that can be removed from the fixed frame 1 and the conveyor 5, so as to facilitate replacement of the support arm assembly 7 matching the conveyor 5. Specifically, 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 on the support arm 701 at one end 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. The first quick-release structure 702 and the second quick-release structure 9 can be quickly released and connected. In an embodiment of the quick-release connection, the first quick-release structure 702 and the second quick-release structure 9 can be plugged in and matched.

[0073] In this embodiment, the support arm assembly 7 can be disassembled after the conveyor 5 is disassembled, and its installation can be before the conveyor 5 is installed. For the same conveyor 5, one or more support arm assemblies 7 can be configured. Of course, one support arm assembly 7 can include multiple support arms 701, and the multiple support arms 701 can be installed together on the same first quick-release structure 702.

[0074] In one embodiment of the first quick-release structure 702 and the second quick-release structure 9, as Figure 6 and Figure 7 As 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 plugged and matched in the vertical direction.

[0075] In order to facilitate the plug-in cooperation between the first connector 7024 and the second connector 901, in this embodiment, the first connector 7024 and the second connector 901 are both configured as wedge-shaped structures, and a first plug-in slot 902 is formed between the inner side of the second connector 901 and the fixed frame 1. The first quick-release structure 702 also includes an outer frame 7020, the first side of the outer frame 7020 is an open structure, 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, a second connecting plate 7023 is provided on the first connecting plate 7021, and the second connecting plate 7023 constitutes a wedge-shaped first connector 7024, so that a second plug-in slot for inserting the second connector 901 is formed between the second connecting plate 7023 and the first connecting plate 7021.

[0076] During installation, the outer frame 7020 is placed on the second connecting member 901 and the first connecting member 7024 is located above the second connecting member 901. At this time, the first plug-in slot 902 corresponds to the first connecting member 7024, and the second plug-in 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 plug-in slot to complete the installation.

[0077] In order to enable the first connector 7024 and the second connector 901 to be accurately plugged and matched, as shown in FIG. Figure 6 As shown, the first quick-release structure 702 in this embodiment also includes a positioning member 7022, which is arranged on both sides of the first connecting member 7024, and the lower end of the positioning member 7022 extends out of the lower end surface of the first connecting member 7024, and the distance between the positioning members 7022 on both sides matches the length of the second connecting member 901.

[0078] Specifically, it should be noted that the positioning members 7022 on both sides form an introduction groove that matches the second connecting member 901. 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 made to correspond to each other up and down, and then the first connecting member 7024 is vertically inserted into the second connecting member 901 to complete the installation. The positioning members 7022 are arranged so that the first connecting member 7024 and the second connecting member 901 can be completely matched without misalignment in the length direction, thereby improving the accuracy of the connection.

[0079] In this embodiment, the positioning member 7022 may be a plate structure that is separately fixed on both sides of the first connecting plate 7021 , or may be a protruding structure that is integrally formed with the first connecting plate 7021 .

[0080] Since the support arm 701 mainly supports the conveyor 5, in order to facilitate the connection and disassembly of the support arm 701 and the conveyor 5, Figure 6 As shown, in this embodiment, a connecting groove 7010 is provided at the second end of the support arm 701 , and a connecting shaft is provided at the lower end of the conveyor 5 , and the connecting shaft is snap-fitted with the connecting groove 7010 .

[0081] In one embodiment of the locking member 2, the locking member 2 is disposed on both sides of the fixed frame 1, and can fix both sides of the silo panel 3 at the same time, thereby further improving the stability of the silo panel 3 after being fixed.

[0082] In this embodiment, if Figure 2 As shown, the locking member 2 includes a rotary wrench 201 and a locking buckle 202. The rotary wrench 201 is arranged on the fixed frame 1, and the locking buckle 202 is arranged on the silo panel 3. The rotary wrench 201 is configured to be able to be inserted into and detached from the locking buckle 202 in a rotational manner.

[0083] Specifically, the locking buckle 202 is fixed to the outside of the silo panel 3, and the side of the locking buckle 202 close to the rotating wrench 201 is set as an opening. The rotating wrench 201 is hinged on the fixed frame 1, and a protrusion is set on the side of the rotating wrench 201 close to the locking buckle 202, and the protrusion can be inserted into the opening in a rotating manner, so as to fix the silo panel 3 on the fixed frame 1. When the silo panel 3 needs to be removed, the rotating wrench 201 can be rotated to make the protrusion disengage from the locking buckle 202. In this embodiment, the locking member 2 makes it easier to fix the silo panel 3 on the fixed frame 1, and no other auxiliary tools or separate fasteners are required.

[0084] Since the connection between the first pneumatic connector 12 and the second pneumatic connector 301 is achieved simultaneously during the installation process of the silo panel 3, when the positions of the first pneumatic connector 12 and the second pneumatic connector 301 are both in fixed positions, in order to achieve precise docking, higher requirements are placed on the position accuracy of the pneumatic connectors.

[0085] In this embodiment, in order to reduce the position accuracy requirements for 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 connected during the installation of the silo panel 3.

[0086] Specifically, Figures 8 to 11 As 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, in which a joint installation cavity 122 is provided; a floating member 123, which is provided in the joint installation cavity 122, and the floating member 123 is axially matched with the joint installation cavity 122 in clearance, 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, and an access port is provided 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 plug hole 3010 connected to the airway is provided in the second pneumatic joint 301, and the quick-change air nozzle 125 is plugged and matched with the quick plug hole 3010.

[0087] In this embodiment, the joint housing 120 is fixed on the fixed frame 1, and specifically can be fixed in the channel structure 101 of the fixed frame 1 so as to directly correspond to the silo panel 3. A through joint installation cavity 122 is provided in the joint housing 120, a floating member 123 is provided in the joint installation cavity 122, and a cavity that penetrates along the axial direction is provided in the floating member 123. The first end of the cavity can be connected to an external gas supply device through a gas valve for gas inflow, and an access port is provided at the second end of the cavity, and a quick-change air nozzle 125 is provided in the access port for gas outflow.

[0088] 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 with the quick-plug hole 3010 in the second pneumatic joint 301. Therefore, in order to achieve the floating of the quick-change air nozzle 125, the structure of the joint installation cavity 122 and the floating member 123 is improved in this embodiment. Specifically, in this embodiment, the floating member 123 is clearance-matched with the joint installation cavity 122 in the axial direction to avoid the floating member 123 and the joint installation cavity 122 being crushed 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. The difference between the radial dimensions of the two 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 generate a certain amount of floating relative to the joint installation cavity 122 in the radial direction.

[0089] 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, thereby completing the connection.

[0090] On the basis of the above-mentioned embodiment, in order to facilitate the docking of the quick-change air nozzle 125 and the quick plug hole 3010, the second end of the quick-change air nozzle 125 in this embodiment is provided with a first introduction surface 1251, and the end of the quick plug hole 3010 is provided with a second introduction surface 3011 that matches the first introduction surface 1251. The first introduction surface 1251 and the second introduction surface 3011 are both conical surfaces. When plugging, the first introduction surface 1251 first contacts the second introduction surface 3011. At this time, the axis of the quick-change air nozzle 125 and the axis of the quick plug hole 3010 may not be colinear. With the further rotation of the silo panel 3, the first introduction surface 1251 and the second introduction surface 3011 always keep in contact. With the cooperation of the two, the quick-change air nozzle 125 generates radial floating in the floating space, and finally the axis of the quick-change air nozzle 125 gradually approaches the axis of the quick plug hole 3010. At this time, the first introduction surface 1251 completely enters the quick plug hole 3010. Then, during the further rotation of the silo panel 3, the quick-change air nozzle 125 will continue to float in the floating space to find the correct position until the quick-change air nozzle 125 reaches the set insertion depth. In this embodiment, by setting the floating member 123 and the quick-change air nozzle 125 as a floating structure, the position accuracy requirements for the first pneumatic joint 12 and the second pneumatic joint 301 are 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 completed synchronously during the installation process of the silo panel 3.

[0091] It is understandable that in another embodiment, the quick-change air nozzle 125 can be fixed in the quick plug hole 3010. 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 and the access port in the floating member 123. The specific docking process is consistent with the above embodiment, and will not be repeated in this embodiment.

[0092] In addition, the second pneumatic joint 301 may 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 may 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 as a fixed structure. In the above embodiment, the quick-change air nozzle 125 may 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.

[0093] In order to prevent the floating member 123 from being separated 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, and the first limiting portion 121 and the second limiting portion 124 are plugged and matched in the radial direction of the floating member 123, and the first limiting portion 121 and the second limiting portion 124 have floating space in the radial direction of the floating member 123. In this embodiment, the axial end surface clearance of the first limiting portion 121 and the second limiting portion 124 is matched to prevent the floating member 123 and the joint installation cavity 122 from being pressed together and causing the inability to generate radial floating.

[0094] In one embodiment, the first limiting portion 121 and the second limiting portion 124 can be respectively configured as a protrusion and a groove structure. Specifically, in one embodiment of the first limiting portion 121 and the second limiting portion 124, the second limiting portion 124 is at least one first protrusion disposed outside the floating member 123, and the first limiting portion 121 is at least one first inner recess disposed in the joint installation cavity 122, the first inner recess and the first protrusion cooperate, and the radial dimension of the first inner recess is greater than the radial dimension of the first protrusion, so as to form a floating space for the floating member 123.

[0095] Specifically, in this embodiment, the first protrusion can be an annular protrusion structure, and the corresponding first inner recess can be an annular groove structure. After the first protrusion is inserted into the second inner recess, the first protrusion and the first inner recess are matched with each other in the axial direction to avoid the floating member 123 from being crushed. The radial size difference between the first protrusion and the first inner recess will determine the radial floating amount of the floating member 123 in the joint installation cavity 122.

[0096] It is understandable that the first protrusion can be configured as a ring-shaped protrusion structure or a plurality of protrusion structures spaced apart along the circumference of the floating member 123. Correspondingly, the first inner recess can also be configured as a groove structure spaced apart along the circumference of the joint installation cavity 122.

[0097] In addition, in another embodiment of the first limiting portion 121 and the second limiting portion 124, the second limiting portion 124 is at least one second recessed portion arranged on the outside of the floating member 123, and the first limiting portion 121 is at least one second protruding portion arranged in the joint mounting cavity 122, the second recessed portion and the second protruding portion cooperate with each other, and the radial dimension of the second recessed portion is smaller than the radial dimension of the first protruding portion.

[0098] In this embodiment, the matching relationship between the second inner concave portion and the second protrusion portion is the same as the matching relationship between the first inner concave portion and the first protrusion portion in the above embodiment. The difference between the two embodiments is that the arrangement positions of the inner concave portion and the protrusion portion are swapped, so this embodiment will not be described in detail here.

[0099] 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. In order to facilitate the floating of the floating member 123, in this embodiment, the joint installation cavity 122 is set to be a circular cavity, and the floating member 123 is set to be cylindrical.

[0100] To ensure gas supply, the first pneumatic connector 12 includes a quick-change nozzle 125, and the second pneumatic connector 301 includes a plurality of quick-change holes 3010. When the first pneumatic connector 12 includes a plurality of quick-change nozzles 125, the connector installation cavity 122 of the connector housing 120 and the floating member 123 have at least two implementations.

[0101] One implementation method is as follows: Figure 8 and Fig. 9 As shown, a plurality of joint installation cavities 122 are provided in the joint housing 120, and a plurality of floating members 123 are provided and 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, and a floating member 123 is installed in each joint installation cavity 122, and an access port is provided in each floating member 123, and a quick air change nozzle 125 is installed.

[0102] Another embodiment is as follows: Fig.10 and Fig.11 As shown, a relatively large joint installation cavity 122 is provided in the joint housing 120, and a plurality of access ports are provided on a 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 embodiment, the plurality of quick-change air nozzles 125 can float as a whole, and the required processing parts are fewer, and the use cost is lower.

[0103] According to another aspect of the present application, a pneumatic quick-change connector assembly is provided, including a first connector and a second connector, wherein the first connector includes the above-mentioned floating pneumatic quick-change connector, and the second connector is provided with a quick socket; the first connector is used to be fixed to a fixed component, and the second connector is used to be fixed to a mold-changing component; or, the first connector is used to be fixed to a mold-changing component, and the second connector is used to be fixed to a fixed component.

[0104] In this embodiment, the fixed component is a fixed frame 1 , and the changeable component is a silo panel 3 .

[0105] According to another aspect of the present application, there is provided a material bin, comprising 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.

[0106] like Figure 12 to Figure 14As shown, in a detachable connection mode of the conveyor 5 and the conveying channel 4 and a fastening mode of the fastening structure 6, a first connecting portion 13 is provided on the conveyor 5, and a second connecting portion 14 is provided in the conveying channel 4, and the first connecting portion 13 and the second connecting portion 14 are detachably plugged and matched;

[0107] The fastening structure 6 includes a pressing portion 601 , which is configured to apply a pressing force to the first connection portion 13 toward the second connection portion 14 , so that the first connection portion 13 can be pressed and fixed on the second connection portion 14 .

[0108] Specifically, in the present embodiment, when the conveyor 5 is installed on the conveying channel 4, the connection between the third pneumatic joint 8 and the fourth pneumatic joint 20 is synchronously completed. The connection between the conveyor 5 and the conveying channel 4 is achieved through the first connecting part 13 and the second connecting part 14. The first connecting part 13 and the second connecting part 14 adopt plug-in matching to make the installation and disassembly of the conveyor 5 more convenient. In order to achieve plug-in matching, one of the first connecting part 13 and the second connecting part 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 vertical plug-in matching is adopted, the opening direction of the groove structure is vertical, and when horizontal plug-in matching is adopted, the opening direction of the groove structure is horizontal.

[0109] On the basis of the plug-in fit between the first connection part 13 and the second connection part 14, in order to further improve the stability of the connection, the fastening structure 6 in this embodiment applies a pressing force to the first connection part 13 so that the first connection part 13 and the second connection part 14 can be tightly connected. Specifically, the fastening structure 6 in this embodiment includes a pressing part 601, which can be operated to apply a pressing force to the first connection part 13 toward the second connection part 14, so that the first connection part 13 can be pressed and fixed on the second connection part 14.

[0110] In this embodiment, the fastening structure 6 is a structure capable of applying a clamping force, and can be a fastening screw, a pressure clamp, or an elastic clamp, etc. In this embodiment, there is no limitation on the specific structure of the fastening structure 6.

[0111] The first connection part 13 is provided with a fourth pneumatic joint 20, and the second connection part 14 is provided with a third pneumatic joint 8. The fourth pneumatic joint 20 and the third pneumatic joint 8 are detachably plugged together; 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 airway in the silo panel 3. The fourth pneumatic joint 20 and the third pneumatic joint 8 are arranged along the plugging direction of the first connection part 13 and the second connection part 14.

[0112] In this embodiment, when the connection direction of the third pneumatic connector 8 and the fourth pneumatic connector 20 is in the same direction as the plug-in direction of the first connection part 13 and the second connection part 14, and the fourth pneumatic connector 20 is arranged on the first connection part 13, the clamping force applied to the first connection part 13 by the clamping part 601 also acts synchronously on the fourth pneumatic connector 20 and the third pneumatic connector 8. Through this clamping force, the first connection part and the second connection part can still maintain a tight connection under the action of the air pressure after ventilation.

[0113] In an embodiment of a connection between the first connection portion 13 and the second connection portion 14, as shown in FIG. Fig.12 As shown, the first connection part 13 and the second connection part 14 are configured to be removably plugged in and matched in the horizontal direction. In this embodiment, the first connection part 13 is provided with a first connection protrusion 130, and the second connection part 14 is provided with a first connection groove 140, and the first connection protrusion 130 and the first connection groove 140 can bite each other.

[0114] Specifically, in this embodiment, the first connection groove 140 has a horizontal opening, and the first connection protrusion 130 corresponds to the first connection groove 140. Fig.12 As shown, when installing the conveyor 5, the conveyor 5 can be first installed in the conveying channel 4 so that the first connecting protrusion 130 is located in front of the first connecting groove 140, and then the conveyor 5 is pushed in the horizontal direction so that the first connecting protrusion 130 is inserted into the first connecting groove 140 and engages with each other (such as Fig.13 Then, the fastening structure 6 can be operated to tightly connect the first connecting protrusion 130 and the first connecting groove 140 (as shown in FIG. Fig.14 shown).

[0115] In this process, in order to synchronously complete the connection between 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 plugging direction of the first connecting portion 13 and the second connecting portion 14. Fig.12 As shown, the fourth pneumatic joint 20 can be arranged at the end of the first connecting protrusion 130, and the third pneumatic joint 8 can be arranged in the first connecting groove 140. Of course, it can be understood that the fourth pneumatic joint 20 can also be arranged at other positions of the first connecting portion 13, and the third pneumatic joint 8 can also be arranged at other positions of the second connecting portion 14. For ease of installation, the inner bottom surface of the first connecting groove 140 is tightly matched with the lower bottom surface of the first connecting protrusion 130, and there is a certain gap between the upper top surface of the first connecting groove 140 and the upper top surface of the first connecting protrusion 130.

[0116] In order to accurately connect the first connecting protrusion 130 and the first connecting groove 140, Fig.12As shown, in this embodiment, a support portion 141 is provided at the lower end of the second connection portion 14 and protrudes from the first connection groove 140 in the horizontal direction. The upper surface of the support portion 141 is flush with the inner bottom surface of the first connection groove 140 .

[0117] During installation, the conveyor 5 can be first vertically loaded into the conveying channel 4 and the lower end of the first connecting part 13 can be placed against the support part 141. At this time, the first connecting protrusion 130 on the first connecting part 13 and the first connecting groove 140 on the second connecting part 14 are opposite to each other in the horizontal direction. Then, the conveyor 5 can be pushed horizontally to complete the docking of the first connecting protrusion 130 and the first connecting groove 140.

[0118] It is understandable that the first connection portion 13 is also configured as a groove structure, and the second connection portion 14 can also be configured as a protrusion structure. The cooperation between the two is the same as the cooperation between the first connection protrusion 130 and the first connection groove 140 in the above embodiment, and will not be repeated here.

[0119] In this embodiment, if Fig.12 As shown, due to the provision of the first connection groove 140, the second connection portion 14 also has a protrusion structure, and the protrusion structure is located above the first connection groove 140. In order to further improve the connection tightness between the first connection portion 13 and the second connection portion 14, a groove structure corresponding to the protrusion structure can be provided on the first connection portion 13, and the groove structure can be located above the first connection protrusion 130, and the protrusion structure and the groove structure are also clearance-matched on the upper top surface.

[0120] Since the conveyor 5 has a certain length, there is a long lever arm between the end of the conveyor 5 and the first connecting portion 13. Therefore, in order to further improve the structural stability of the conveyor 5 after installation, as shown in FIG. Fig.12 As shown, in this embodiment, a second connecting groove 142 is provided on the second connecting portion 14, and a second connecting protrusion 16 is provided on the conveyor 5. The second connecting groove 142 includes a vertical opening 1420 and a horizontal groove body 1421. The second connecting protrusion 16 is configured to be able to pass through the vertical opening 1420 vertically and be inserted into the horizontal groove body 1421 in the horizontal direction.

[0121] Specifically, in this embodiment, the second connection groove 142 and the first connection groove 140 are distributed in the horizontal direction on the connection portion. Fig.12As shown, the conveyor 5 is vertically loaded into the conveying channel 4, and at the same time, the lower end of the first connecting portion 13 is against the supporting portion 141, and the second connecting protrusion 16 is loaded 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 to each other, and the second connecting protrusion 16 and the horizontal groove body 1421 are horizontally opposite to each other, and then the conveyor 5 can be pushed to make the first connecting protrusion 130 stuck in the first connecting groove 140, and the second connecting protrusion 16 stuck in the horizontal groove body 1421 (as shown in FIG. Fig.13 In this embodiment, the engagement between the first connection protrusion 130 and the first connection groove 140, and the engagement between the second connection protrusion 16 and the horizontal groove 1421 can better resist the downward tilt force on the conveyor 5, thereby further improving the structural stability of the conveyor 5 after installation.

[0122] In order to facilitate the second connecting protrusion 16 to be inserted into the vertical opening 1420 , in this embodiment, the vertical opening 1420 may be configured as an upward flaring structure.

[0123] In one embodiment of the fastening structure 6, the fastening structure 6 is arranged on the silo panel 3, and in order to facilitate the operation of the pressing part 601, as shown in FIG. Fig.12 As shown, the fastening structure 6 in this embodiment also includes an operating part 602, which is connected to the clamping part 601 and is used to operate the clamping part 601 to apply pressure to the first connecting part 13 in the plug-in direction of the first connecting part 13, and to operate the clamping part 601 to disengage from the first connecting part 13.

[0124] Specifically, it should be noted that the operating part 602 and the clamping part 601 are follower structures, which drive the clamping part 601 to move by controlling the operation part 602 to apply pressure to the first connecting part 13, so that the first connecting part 13 can be tightly connected with the second connecting part 14, and at the same time, the gas pressure of the fourth pneumatic connector 20 and the third pneumatic connector 8 at the docking position during the gas flow process can be resisted.

[0125] Further, the operating portion 602 is configured to be able to operate the pressing portion 601 to rotate and press on the first connecting portion 13, and to be able to operate the pressing portion 601 to rotate and detach from the first connecting portion 13. In this embodiment, the fastening structure 6 is configured as a pressing clamp, the operating portion 602 is an operating handle of the pressing clamp, and the pressing portion 601 is a 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 detached from the first connecting portion 13 by controlling the rotation of the operating handle.

[0126] 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.

[0127] 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.

[0128] To this end, the present embodiment further improves the structure of the conveyor 5:

[0129] 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 rotatably arranged at the first end and the second end of the frame 51 respectively; a conveyor belt 18 is sleeved on the conveying wheels 17 at both ends, and the conveyor 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.

[0130] 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.

[0131] 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.

[0132] In one embodiment of the rack 51, as Fig.15 As shown, the frame 51 includes a first side plate 511 and a second side plate 513. The first side plate 511 and the second side plate 513 are arranged opposite to each other and can be fixedly connected by a belt support plate and a plurality of connecting columns. The installation chamber 52 is located in the area between the first side plate 511 and the second side plate 513.

[0133] Based on the above embodiment, the frame 51 also includes a first end plate 510 and a second end plate 512, the first end plate 510 is located between the first ends of the first side plate 511 and the second side plate 513, and the second end plate 512 is located between the second ends of the first side plate 510 and the second side plate 511.

[0134] In this embodiment, multiple parts of a plate can be bent to form the first side plate 511, the second side plate 513, the first end plate 510 and the second end plate 512 respectively, or the first side plate 511, the second side plate 513, the first end plate 510 and the second end plate 512 are all separate plates, which are spliced ​​together to form the frame 51, or some of the first side plate 511, the second side plate 513, the first end plate 510 and the second end plate 512 are formed by bending a plate, and the remaining plates are separately spliced ​​plates.

[0135] In this embodiment, the first side plate 511, the second side plate 513, the first end plate 510 and the second end plate 512 together form a substantially frame-shaped frame 51. The driving mechanism 19 and the conveying wheel 17 are both disposed in the installation chamber 52 of the frame 51, and the conveying wheel 17 is hinged to the first side plate 511 and the second side plate 513 via a rotating shaft.

[0136] In one embodiment of the driving mechanism 19, Fig.16 As shown, the driving mechanism 19 includes a reciprocating mechanism 191 and a one-way rotating mechanism 192;

[0137] The one-way rotating mechanism 192 includes a first rotating part 1921 and a second rotating part 1920. In a first rotating direction, the first rotating part 1921 can drive the second rotating part 1920 to rotate synchronously. In a second rotating direction, the first rotating part 1921 can rotate independently relative to the second rotating part 1920. The second rotating part 1920 is fixedly connected to the corresponding conveying wheel 17.

[0138] The output end of the reciprocating motion mechanism 191 is transmission-connected to the first rotating part 1921 , and is used to drive the first rotating part 1921 to rotate in the first rotation direction and the second rotation direction.

[0139] 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] In one embodiment of the one-way rotating mechanism 192, the one-way rotating mechanism 192 is configured as a ratchet assembly, which includes an inner ring with ratchet teeth and an outer ring with a sliding plate. In the direction of the ratchet teeth, the rotation of the inner ring will drive the outer ring to rotate, and in the direction opposite to the ratchet teeth, the rotation of the inner ring does not act on the outer ring.

[0145] In another embodiment of the one-way rotating mechanism 192, the one-way rotating mechanism 192 includes a one-way bearing assembly, the first rotating portion 1921 includes an outer bearing ring of the one-way bearing assembly, and the second rotating portion 1920 includes an inner bearing ring of the one-way bearing assembly.

[0146] Based on the above embodiment, the one-way bearing assembly includes a one-way bearing and a bearing seat. The outer ring of the one-way bearing is sleeved and fixed in the bearing seat. The outer ring of the bearing and the bearing seat constitute a first rotating part 1921. The inner ring of the one-way bearing is fixedly connected to the conveying wheel 17 through a rotating shaft, and the bearing seat is transmission-connected to the output end of the reciprocating motion mechanism 191.

[0147] Specifically, in this embodiment, the bearing seat can be a roughly annular structure, the bearing seat is sleeved and fixed on the outer ring of the one-way bearing, and the 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 transmission-connected to the bearing seat, it can drive the bearing seat and the outer ring of the bearing to rotate.

[0148] In one embodiment of the reciprocating mechanism 191, Fig.16 As shown, the reciprocating motion mechanism 191 includes a first linear motion component 1910, a driving end of the first linear motion component 1910 is hinged to the frame 51, and an output end of the first linear motion component 1910 is hinged to the bearing seat.

[0149] Specifically, it should be noted that the first linear motion component 1910 in this embodiment is a component capable of outputting reciprocating linear motion, and may be a linear motion cylinder, a linear motion motor, or a screw transmission mechanism, etc. In order to convert the linear motion outputted by the first linear motion component 1910 into a force for driving the outer ring of the bearing to rotate, in this embodiment, 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. When the first linear motion component 1910 outputs linear motion, it will push the bearing seat to rotate, and the first linear motion component 1910 will also rotate around the hinge point, thereby driving the outer ring of the bearing to rotate.

[0150] In a specific application, when the first linear motion assembly 1910 outputs an outwardly extending linear motion, the bearing seat and the outer ring of the bearing are driven to rotate counterclockwise, and the inner ring of the bearing remains stationary, so that the conveying wheel 17 and the conveying belt 18 are stationary. When the first linear motion assembly 1910 outputs an inwardly retracting linear motion, the bearing seat and the outer ring of the bearing are driven to rotate clockwise, and the inner ring of the bearing rotates synchronously, so that the conveying wheel 17 and the conveying belt 18 move synchronously.

[0151] In another embodiment of the reciprocating mechanism 191, Fig.17 As shown, the reciprocating motion mechanism 191 includes a second linear motion assembly 1912, a transmission wheel 1914, a transmission belt 1915 and a belt clamp 1913;

[0152] There are at least two transmission wheels 1914 that are rotatable, and the transmission belt 1915 is sleeved on the transmission wheel 1914 .

[0153] Specifically, it should be noted that in this embodiment, the transmission wheel 1914 and the transmission belt 1915 form a group of belt conveyor 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 driven by the second linear motion component 1912. The second linear motion component 1912 can also use a device that can output linear motion, such as a linear motion cylinder, a linear motion motor or a screw transmission mechanism. In order to enable the second linear motion component 1912 to drive the transmission belt 1915 to move, in this embodiment, a belt clamp 1913 is fixed on the transmission belt 1915, and the output end of the second linear motion component 1912 is fixedly connected to the belt clamp 1913. In order to enable the rotation of the transmission wheel 1914 to act on the conveying wheel 17, in this embodiment, one transmission wheel 1914 is fixedly connected to the outer ring of the one-way bearing component.

[0154] In a specific application, when the second linear motion assembly 1912 outputs an outwardly extending linear motion, the belt clamp 1913 drives the transmission belt 1915 to move forward and drives the transmission wheel 1914 to rotate clockwise. Under the action of the transmission wheel 1914, the outer ring of the bearing rotates clockwise synchronously, driving the inner ring of the bearing and the conveying wheel 17 to rotate clockwise, thereby driving the conveying belt 18 to move. When the second linear motion assembly 1912 outputs an inwardly retracting linear motion, the belt clamp 1913 drives the transmission belt 1915 to move backward and drives the transmission wheel 1914 to rotate counterclockwise. Under the action of the transmission wheel 1914, the outer ring of the bearing rotates counterclockwise synchronously. At this time, the inner ring of the bearing and the conveying wheel 17 remain stationary, that is, the conveying belt 18 remains stationary.

[0155] In one embodiment of the conveying wheel 17, Fig.16 As shown, the conveying wheel 17 fixedly connected to the inner ring of the bearing of the one-way bearing assembly includes a first wheel body 170 and a second wheel body 171 arranged opposite to each other, the one-way bearing assembly is arranged 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 inner ring of the bearing of the one-way bearing assembly are fixedly connected.

[0156] Specifically, it should be noted that in this embodiment, by providing 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 provided 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, thereby improving the movement stability of the conveying wheel 17.

[0157] In one 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;

[0158] like Fig.15 As shown, an air pipe is also provided in the installation chamber 52, a joint is provided on the frame 51, a first end of the air pipe is connected to the joint, and a second end of the air pipe is connected to the linear motion cylinder.

[0159] 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 corner 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 joint, namely the fourth pneumatic joint 20, is provided on the frame 51 in this embodiment.
