Description

Technical Field

[0001] This invention belongs to the technical field of feeding equipment, and particularly relates to a feeding structure and a feeding device for fasteners. Background Technology

[0002] Current screw feeding equipment contains multiple receiving bins for storing screws. During the feeding process, a large number of screws to be processed or sorted need to be collected into the feeding device, which then transports the screws one by one or in batches to the various receiving bins. However, existing feeding structures often have some shortcomings. For example, some feeding devices lack an effective locking mechanism when pouring material onto the receiving component, which may cause the movable receiving component to move unexpectedly during the material pouring process, resulting in material spillage. This not only wastes material but also affects the accuracy and efficiency of feeding. Summary of the Invention

[0003] In view of the above-mentioned problems existing in the prior art, the purpose of the present invention is to provide a feeding device for a feeding structure and fasteners.

[0004] The technical solution adopted in the embodiments of the present invention is as follows: A feeding structure, comprising: frame; The first component includes a fixed bracket, a feeding cylinder disposed on the fixed bracket, and a first locking mechanism. The fixed bracket is disposed on the frame, and the feeding cylinder has a cylinder cover. The second component includes a movable support and a receiving cylinder disposed on the movable support. The movable support is connected to the frame and is capable of moving relative to the frame. When the movable support moves to the target position, opening the cylinder cover can trigger the first locking mechanism to lock the movable support, and the receiving cylinder can receive the material in the feeding cylinder; when the cylinder cover is closed, the first locking mechanism can release the movable support, so that the movable support can move away from the target position.

[0005] In some embodiments, the first component further includes a second locking mechanism disposed on the fixed bracket; When the movable support moves away from the target position, the second locking mechanism locks the cylinder cover, keeping the cylinder cover closed over the feeding cylinder; when the movable support moves to the target position, the movable support can trigger the second locking mechanism to release the cylinder cover.

[0006] In some embodiments, the second locking mechanism includes a second mounting bracket and a second target member and an elastic member respectively disposed on the second mounting bracket; The cap has a fourth target member, and the second target member is used to cooperate with the fourth target member to lock the cap; the elastic member is used to apply a force in a first direction to the second target member; the first direction is the cooperation direction of the second target member and the fourth target member; The movable support or the receiving cylinder has a pushing part. During the process of the movable support moving to the target position, the pushing part can push the second target member to move in the second direction, so as to disengage the second target member and the fourth target member.

[0007] In some embodiments, the outer peripheral wall of the pushing part has an arcuate surface and a horizontal surface, and the second target member has a rod-shaped part; During the movement of the movable support, the pushing part can abut against the rod part through the arc-shaped surface to push the second target part to move along the second direction; When the movable bracket moves to the target position, the horizontal plane of the pushing part abuts against the rod part, so that the second locking mechanism remains in the state of releasing the cylinder cover.

[0008] In some embodiments, the fourth target component is disposed on the inner wall surface of the cylinder cover, and the cylinder wall of the feeding cylinder has a through hole; When the cylinder cover is closed, the second target component can pass through the through hole to engage with the fourth target component.

[0009] In some embodiments, the second component further includes a feeding plate and a driving component; The feeding plate and the driving component are respectively mounted on the movable support and can move synchronously with the movable support; the driving component is connected to the feeding plate and is used to drive the feeding plate to move relative to the receiving cylinder to open or close the receiving cylinder. When the cover is open and the feeding cylinder is open, the first locking mechanism can lock the discharging plate so that the discharging plate is in a state of keeping the receiving cylinder closed.

[0010] In some embodiments, the first locking mechanism includes a first mounting bracket and a first target member disposed on the first mounting bracket; the cylinder cover is drively connected to the first target member, and the movable bracket has a third target member; When the cylinder cover opens the feeding cylinder, it can drive the first target component to move synchronously to cooperate with the third target component, thereby locking the movable bracket; When the cylinder cover closes the feeding cylinder, it can drive the first target component to move synchronously to disengage from the third target component, thereby releasing the movable support.

[0011] In some embodiments, the cap has a lever, and the first target member has a drive pin; The lever is slidably connected to the drive pin. During the process of opening or closing the feeding cylinder, the lever can slide relative to the drive pin to drive the first target component to engage or disengage with the third target component.

[0012] In some embodiments, the side wall of the feeding cylinder has a notch, the lever passes through the notch, the lever is fixedly connected to the cylinder cover, and can rotate synchronously with the cylinder cover.

[0013] A fastener feeding device, comprising: A feeding structure as described in any of the above embodiments; Multiple receiving bins are arranged around the frame and located below the receiving cylinder; The movable support can selectively move the receiving cylinder above each receiving bin to release the material received in the receiving cylinder into the corresponding receiving bin.

[0014] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows: In this embodiment, the movable support of the feeding structure can move relative to the frame. After moving to the target position, opening the cylinder cover triggers the first locking mechanism to lock the movable support, ensuring that the material in the feeding cylinder falls accurately and without omission into the receiving cylinder. When the material addition is complete and the cylinder cover is closed, the first locking mechanism automatically releases the movable support, allowing it to move smoothly away from the target position and continue performing subsequent feeding tasks. This design cleverly links the opening and closing action of the cylinder cover with the locking state of the movable support, achieving mechanical interlocking and effectively preventing material spillage or equipment failure caused by accidental movement of the movable support during material receiving, greatly improving the stability and reliability of the feeding process.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly. To keep the following description of the embodiments of this invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0022] like Figures 1 to 4 As shown, this application embodiment provides a feeding structure, which includes a frame 1 and a first component 2 and a second component 3 on the frame 1 respectively.

[0023] The first component 2 includes a fixed bracket 21, a feeding cylinder 22 mounted on the fixed bracket 21, and a first locking mechanism 23. The feeding cylinder 22 has a cylinder cover 220, which can be used to open or close the feeding cylinder 22.

[0024] The second component 3 includes a movable support 32 and a receiving cylinder 31 mounted on the movable support 32. The movable support 32 can move relative to the fixed support 21 or the frame 1. When the movable support 32 moves to the target position, the cylinder cover 220 can be opened and material can be fed through the feeding cylinder 22. At this time, the receiving cylinder 31 can receive the material in the feeding cylinder 22. When the movable support 32 is in the target position and the cylinder cover 220 is open, the cylinder cover 220 can trigger the first locking mechanism 23 to lock the movable support 32, thereby preventing the movable support 32 from moving.

[0025] It should be noted that the target position in this embodiment can be the docking position of the receiving cylinder 31 and the feeding cylinder 22. At this position, the axes of the receiving cylinder 31 and the feeding cylinder 22 can be coaxial or the distance between their axes can be within a reasonable range, so that the material can enter the receiving cylinder 31 through the feeding cylinder 22.

[0026] In this embodiment, the movable support 32 in the feeding structure can move relative to the frame 1. After moving to the target position, opening the cylinder cover 220 triggers the first locking mechanism 23 to lock the movable support 32. This ensures that the material in the feeding cylinder 22 can fall accurately and without omission into the receiving cylinder 31. When the material addition is completed and the cylinder cover 220 is closed, the first locking mechanism 23 will automatically release the movable support 32, allowing it to move smoothly away from the target position and continue to perform subsequent feeding tasks. This design cleverly links the opening and closing action of the cylinder cover 220 with the locking state of the movable support 32, achieving mechanical interlocking. This effectively prevents material spillage or equipment failure caused by accidental movement of the movable support 32 during material receiving, greatly improving the stability and reliability of the feeding process. like Figures 4 to 6 As shown, in some embodiments, the first component 2 may further include a second locking mechanism 24 disposed on the fixed bracket 21. The second locking mechanism 24 is used to lock or release the cylinder cover 220.

[0027] When the movable support 32 moves away from the target position, the second locking mechanism 24 locks the cylinder cover 220, keeping the cylinder cover 220 closed over the feeding cylinder 22, preventing the user from opening the cylinder cover 220. When the movable support 32 moves to the target position, it triggers the second locking mechanism 24 to release the cylinder cover 220, allowing the user to open the cylinder cover 220 and feed material into the feeding cylinder 22. At this time, opening the cylinder cover 220 also locks the movable support 32 again via the first locking mechanism 23. Therefore, the cylinder cover 220 can only be opened when the movable support 32 accurately moves to the target position and triggers the second locking mechanism 24 to release the cylinder cover 220, while the first locking mechanism 23 locks the movable support 32, forming a double mechanical interlocking mechanism. This dual-locking design further ensures the safety and accuracy of the feeding operation, preventing the material from spilling out due to accidental opening of the cylinder cover 220 when the movable support 32 is not in place, or the movable support 32 from moving during the receiving process. It provides strict logical control over the entire feeding process from a mechanical structure perspective.

[0028] like Figure 5 and Figure 6 As shown, in some embodiments, the second locking mechanism 24 may include a second mounting bracket 242 and a second target member 241 and an elastic member 243 disposed on the second mounting bracket 242.

[0029] The cylinder cover 220 may have a fourth target member 222. The second target member 241 is used to cooperate with the fourth target member 222 to lock the cylinder cover 220 so that the cylinder cover 220 remains in the closed state of the feeding cylinder 22. When the second target member 241 and the fourth target member 222 are disengaged, the cylinder cover 220 is released and can be opened freely.

[0030] In this embodiment, the elastic member 243 is used to apply a force in a first direction to the second target member 241. The first direction is the mating direction between the second target member 241 and the fourth target member 222.

[0031] The movable support 32 or the receiving cylinder 31 has a pushing part 36. When the movable support 32 moves to the target position, the pushing part 36 can push the second target member 241 to move in the second direction. At this time, the elastic member 243 is compressed, causing the second target member 241 to disengage from the fourth target member 222. After the material is loaded and the feeding cylinder 22 is closed, after the movable member leaves the target position, the second target member 241 can move automatically under the force applied by the elastic member 243, thereby engaging with the fourth target member 222 again and locking the cylinder cover 220 again without the need for an additional power source.

[0032] Specifically, the second mounting bracket 242 can be fixed on the fixed bracket 21, the second target member 241 is slidably disposed on the second mounting bracket 242, one end of the elastic member 243 abuts against the second mounting bracket 242, and the other end abuts against the second target member 241, so as to continuously apply an elastic force toward the fourth target member 222 to the second target member 241.

[0033] When the movable support 32 is not in the target position, the second target component 241 engages with the fourth target component 222 under the action of the elastic component 243, preventing the cylinder cover 220 from being opened. When the movable support 32 moves to the target position, the pushing part 36 (e.g., a protrusion or push rod) on the movable support 32 pushes against the second target component 241, causing the second target component 241 to overcome the elastic force of the elastic component 243 and move in the second direction (opposite to the first direction), thereby disengaging from the fourth target component 222 and releasing the cylinder cover 220. This structure is simple and reliable, utilizing the reset characteristic of the elastic component 243 to achieve automatic restoration of the locked state without the need for an additional power source.

[0034] In this embodiment, the elastic element 243 can be a spring, such as a cylindrical helical spring, a disc spring, or a leaf spring. For example, as... Figure 6 As shown, when the elastic element 243 is a cylindrical helical spring, the elastic element 243 can be directly fitted onto the second target element 241.

[0035] Continue as Figure 5 and Figure 6As shown, in this embodiment, the second target component 241 can be constructed as a pin, and the structure of the fourth target component 222 is not specifically limited. The fourth target component 222 may be provided with a pin hole. When the second target component 241 is inserted into the pin hole of the fourth target component 222, the cylinder cover 220 is locked, and thus the cylinder cover 220 cannot be opened.

[0036] In some embodiments, the fourth target 222 may be disposed on the inner wall surface of the cylinder cover 220, and the cylinder wall of the feeding cylinder 22 may be provided with a through hole. When the cylinder cover 220 closes the feeding cylinder 22, the second target 241 may pass through the through hole and extend into the interior of the feeding cylinder 22 to cooperate with the fourth target 222, thereby locking the cylinder cover 220.

[0037] When the movable bracket 32 ​​rotates to the target position, it can push the second target part 241 to extend to the outside of the feeding cylinder 22. At this time, the cylinder cover 220 can be opened, and then the material can be fed through the feeding cylinder 22. Since the second target part 241 has been moved to the outside of the feeding cylinder 22, it will not affect the feeding process.

[0038] like Figures 4 to 6 As shown, in some embodiments, the pushing part 36 may be provided on the receiving cylinder 31, and the first target member 231 has a rod portion 244. During the movement of the movable support 32, the receiving cylinder 31 abuts against the rod portion 244 through the pushing part 36, thereby pushing the first target member 231 to move in the second direction and compressing the elastic member 243. When the movable support 32 moves to the target position, the pushing part 36 remains in contact with the rod portion 244, so that the first target member 231 and the third target member 35 are in a disengaged state.

[0039] In this embodiment, the outer peripheral wall of the pushing part 36 may have a connecting arc-shaped surface 361 and a horizontal surface 362. When the movable support 32 moves to a position close to the target position, the arc-shaped surface 361 of the pushing part 36 may first contact the rod part 244. As the movable support 32 continues to move, the arc-shaped surface 361 gradually applies a pushing force to the rod part 244, causing the second target part 241 to move slowly along the second direction, avoiding violent impact. When the movable support 32 reaches the target position, the horizontal surface 362 of the pushing part 36 is completely in contact with the rod part 244, ensuring that the second target part 241 is stably maintained in a state of disengagement from the fourth target part 222, providing stable operating conditions for the operator to open the cylinder cover 220.

[0040] In this embodiment, the opening of the receiving cylinder 31 may have an outwardly extending protrusion, which can form a pushing part 36. When the movable bracket 32 ​​moves to the target position, the protrusion at the opening of the receiving cylinder 31 abuts against the rod part 244 of the second target member 241. The protrusion applies a continuous pushing force to the rod part 244, so that the second target member 241 overcomes the force of the elastic member 243 and remains in the second direction, ensuring that the second target member 241 and the fourth target member 222 are always in a disengaged state.

[0041] like Figure 3 As shown, in some embodiments, the first locking mechanism 23 may include a first mounting bracket 232 and a first target component 231 disposed on the first mounting bracket 232. The first mounting bracket 232 may be fixed on the fixed bracket 21, and the cylinder cover 220 is convexly connected to the first target component 231. When the cylinder cover 220 opens the feeding cylinder 22, the cylinder cover 220 may drive the first target component 231 to move relative to the fixed bracket 21.

[0042] The movable support 32 has a third target component 35. When the cylinder cover 220 opens the feeding cylinder 22, the cylinder cover 220 can drive the first target component 231 to move synchronously. The first target component 231 then cooperates with the third target component 35, thereby locking the entire movable support 32. When the cylinder cover 220 closes the feeding cylinder 22, the cylinder cover 220 can again drive the first target component 231 to move synchronously, thereby releasing the cooperation with the third target component 35 and thus releasing the entire movable support 32.

[0043] The first target component 231 and the third target component 35 can be engaged by a plug-in connection. For example, the first target component 231 can be a pin, and the third target component 35 can be a pin hole. When the cylinder cover 220 is opened, the pin is inserted into the pin hole to lock the movable bracket 32. When the cylinder cover 220 is closed, the pin is pulled out of the pin hole to release the movable bracket 32.

[0044] Alternatively, the first target component 231 and the third target component 35 can also be magnetically coupled. For example, the first target component 231 is a magnet, and the third target component 35 is a metal block that can be magnetically attracted. The movable support 32 can be locked or released by the attraction and separation of the first target component 231 and the third target component 35.

[0045] In this embodiment, there are several ways to drive the cylinder cover 220 and the first target component 231. For example, it can be achieved through a linkage mechanism, a gear and rack mechanism, or a cam mechanism.

[0046] For example, such as Figure 3 and Figure 4As shown, the cylinder cover 220 may have a lever 221, and the first target component 231 may have a drive pin 233. The lever 221 and the drive pin 233 are slidably connected. During the opening or closing of the feeding cylinder 220, the lever 221 can slide relative to the drive pin 233, and through the drive pin 233, it drives the first target component 231 to slide relative to the first mounting bracket 232, thereby engaging or disengaging with the third target component 35.

[0047] Specifically, when the cover 220 opens the feeding cylinder 22, the cover 220 drives the first target component 231 to move synchronously so that it cooperates with the third target component 35. At this time, the movable bracket 32 ​​is locked. When the cover 220 closes the feeding cylinder 22, the cover 220 will drive the first target component 231 to move synchronously again so as to disengage from the third target component 35. At this time, the movable bracket 32 ​​is in the released state and can move freely.

[0048] In this embodiment, the lever 221 may have a drive guide groove, and the drive pin 233 may extend into the drive guide groove. When the lever 221 rotates with the cylinder cover 220, the drive pin 233 may slide along the drive guide groove. The lever 221 may abut against the drive pin 233 through the groove wall of the drive guide groove, thereby driving the first target part 231 to move.

[0049] Furthermore, in this embodiment, the structural forms of the first mounting bracket 232 and the first target component 231 are not specifically limited. For example, such as... Figure 3 As shown, the first mounting bracket 232 can be constructed as a cylindrical component, the first target component 231 can be a pin component extending into the first mounting bracket 232, the side wall of the first mounting bracket 232 can have a guide groove, the extension direction of the guide groove is consistent with the movement direction of the first target component 231, and the drive pin 233 of the first target component 231 can pass through the guide groove and extend outward to connect with the lever 221 of the cylinder cover 220.

[0050] like Figure 7 and Figure 8 As shown, in some embodiments, the second component 3 may further include a feeding plate 30 and a driving component 34. The feeding plate 30 and the driving component 34 are respectively disposed on the movable support 32 and are capable of moving synchronously with the movable support 32.

[0051] The receiving cylinder 31 can be a cylindrical structure with open ends. The driving component 34 is connected to the discharging plate 30 and is used to drive the discharging plate 30 to move relative to the receiving cylinder 31, so as to open or close the bottom open end of the receiving cylinder 31. When the receiving cylinder 31 moves to the target position with the movable bracket 32, the receiving cylinder 31 docks with the feeding cylinder 22, so that the material fed through the feeding cylinder 22 can be poured into the holding box through the receiving cylinder 31. During the process of pouring material into the receiving cylinder 31 through the feeding cylinder 22, the discharging plate 30 is in the state of closing the bottom open end of the receiving cylinder 31. At this time, the material entering the receiving cylinder 31 is temporarily stored inside the receiving cylinder 31 to avoid the material falling directly and causing dust or impact. When the material in the receiving cylinder 31 reaches the preset amount or the feeding cylinder 22 completes one feeding cycle, the driving component 34 drives the discharging plate 30 to move, opening the bottom opening of the receiving cylinder 31. The material then falls smoothly from the receiving cylinder 31 into the receiving hopper below or into the subsequent conveying device under the action of gravity. The discharging plate 30 enables intermittent material feeding, making it easy to control the material flow rate and timing, and is especially suitable for scenarios that require quantitative or batch processing of materials.

[0052] In this embodiment, the drive component 34 can be a cylinder, a motor screw assembly, or an electromagnetic push rod, etc. Its movement can be precisely controlled by the control system according to the rhythm of the feeding process, ensuring the automation and accuracy of the entire feeding process.

[0053] In this embodiment, when the cover 220 is open and the feeding cylinder 22 is open, the first locking mechanism 23 can also lock the discharging plate 30, so that the discharging plate 30 is in a state of keeping the receiving cylinder 31 closed. When the feeding is completed and the cover 220 is closed, the first locking mechanism 23 is disengaged from the discharging plate 30, and the driving component 34 can then drive the discharging plate 30 to open the bottom open end of the receiving cylinder 31. This design ensures that the discharging plate 30 is locked closed only when the movable bracket 32 ​​is in place and the cover 220 is open for feeding, preventing premature material leakage; and the closing of the cover 220 is both a signal that feeding is complete and simultaneously releases the lock on the discharging plate 30, allowing it to unload under the action of the driving component 34. This linkage control further improves the orderliness and reliability of the feeding process, avoiding material waste or equipment failure caused by misoperation.

[0054] like Figure 3As shown, in some embodiments, the first target component 231 can be a pin, and the third target component 35 and the feeding plate 30 can be respectively provided with pin holes. When the driving component 34 drives the feeding plate 30 to close the bottom open end of the receiving cylinder 31, the pin hole on the feeding plate 30 is opposite to the pin hole on the third target component 35. At this time, the cylinder cover 220 is opened, and the lever 221 will drive the first target component 231 (pin) to insert into the pin hole of the third target component 35 and the pin hole of the feeding plate 30 through the driving pin 233, thereby locking the movable bracket 32 ​​and the feeding plate 30 at the same time.

[0055] In this way, during the process of adding material into the receiving cylinder 31, the discharge plate 30 will not open accidentally, ensuring that all the material can be temporarily stored in the receiving cylinder 31. When the material is added and the cylinder cover 220 is closed, the lever 221 reverses and drives the second target part 241 to exit from the pin hole, which releases both the locking of the movable bracket 32 ​​and the locking of the discharge plate 30. At this time, the drive component 34 can drive the discharge plate 30 to open, allowing the material to fall.

[0056] like Figure 3 As shown, in some embodiments, the feeding mechanism further includes a discharge cylinder 33, which is also mounted on the movable support 32 and located below the receiving cylinder 31. The material in the receiving cylinder 31 can fall into a designated area through the discharge cylinder 33. For example, a receiving bin 4 can be provided below the discharge cylinder 33, and the material passing through the discharge cylinder 33 falls directly into the receiving bin 4. The structure of the discharge cylinder 33 can be adapted to the material characteristics and conveying requirements. For example, for granular or powdery materials, the discharge cylinder 33 can adopt a cylindrical or square cylinder structure with a smooth inner wall to reduce the risk of material residue and blockage during the conveying process; for easily dusty materials, the discharge cylinder 33 can be designed with a dust removal interface to promptly remove the dust raised by an external dust removal device, improving the working environment.

[0057] like Figure 1 and Figure 2 As shown, in some embodiments, the movable support 32 and the movable support 32 can each be constructed as suspended plate members. The fixed support 21 and the movable support 32 are spaced apart in the height direction of the frame 1, with the fixed support 21 located above the movable support 32. A drive motor 37 may be provided on the frame, which is used to connect to the movable support 32 and drive the movable support 32 to rotate relative to the fixed support 21.

[0058] The feeding cylinder 22 can be connected to the free end of the fixed bracket 21, and the receiving cylinder 31 is also located at the free end of the movable bracket 32. The movable bracket 32 ​​is rotatably connected to the frame 1. When the movable bracket 32 ​​rotates relative to the frame 1, the pushing part 36 on the receiving cylinder 31 triggers the first locking mechanism 23.

[0059] like Figure 9 As shown in the illustration, this application also provides a fastener feeding device, which includes a feeding structure as described in any of the above embodiments. Multiple receiving bins 4 are located below the receiving cylinder 31. The feeding cylinder 22 in the feeding structure is located above the receiving cylinder 31 and is fixed in place.

[0060] When multiple receiving bins 4 need to be fed, the movable support 32 can be rotated to the target position first, and the material can be placed in the receiving bin 31 for temporary storage through the feeding cylinder 22. Then, the movable support 32 drives the receiving bin 31 to selectively move above each receiving bin 4, and the discharge plate 30 is opened to release the material received in the receiving bin 31 into the corresponding receiving bin 4 through the discharge cylinder 33.

[0061] In this embodiment, the arrangement of the multiple receiving bins is not specifically limited. They can be distributed in a circle around the rotation axis of the movable support 32, arranged in a straight line, or flexibly adjusted according to the actual production layout. The connection structure between the movable support 32 and the frame 1 corresponds to the arrangement of the multiple receiving bins.

[0062] For example, when multiple receiving bins are distributed along a circumference, the movable support 32 can rotate to align the receiving cylinder 31 with different receiving bins in sequence; when the receiving bins are arranged in a straight line, the movable support 32 can be designed as a linear sliding structure to move the receiving cylinder 31 horizontally above each receiving bin. This design enables the feeding equipment to achieve precise delivery to multiple workstations or different types of materials, greatly improving production efficiency and automation.

[0063] like Figure 10 As shown, in some embodiments, the feeding device may further include a housing 5, which covers the entire frame 1 and the second component 3. The top of the housing 5 has a feeding port, into which the feeding cylinder 22 of the feeding mechanism is embedded. An operating window may be provided on the side of the housing 5 to facilitate operators' observation of the internal operation of the equipment and to perform necessary maintenance. The operating window may be equipped with a transparent observation panel and an openable protective door to ensure both convenient observation and operational safety.

[0064] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
