Description

Technical Field

[0001] This utility model relates to the field of processing and feeding equipment technology, and specifically to a flip-feeding device that is easy to lock. Background Technology

[0002] With the improvement of industrial automation, traditional manual feeding can no longer meet the batch operation requirements of modern production lines. Multi-track feeding equipment has become a key auxiliary device for improving production efficiency because it can realize the orderly orientation and synchronous transportation of small workpieces. During long-term operation, such equipment requires frequent cleaning, replacement or adjustment of the discharge track. Therefore, the convenience and reliability of its flip-over maintenance structure are crucial.

[0003] Chinese Patent Publication No. CN222630528U discloses a discharge nozzle flipping structure and a feeder. This structure, through a rotating connection between a bottom support plate and a top support plate, can cause the discharge nozzle to disengage from the discharge track for easier maintenance, reducing the complexity of disassembly and assembly to some extent. However, this flipping structure has a significant drawback: its locking and unlocking rely entirely on screw operation. Screws must be loosened using a screwdriver or similar tool before it can be flipped, adjusted, and then tightened again. This cumbersome process and strong tool dependence severely impact maintenance efficiency.

[0004] More importantly, there is no intuitive way to judge the tightness of screws. It is difficult to detect loose or slack screws with the naked eye, and workers are prone to improper tightening due to operational oversights or memory errors. In addition, the feeding equipment is usually accompanied by continuous vibration during operation. The loose flipping structure is very easy to loosen and shift, which may not only cause equipment failures such as material conveying jams and inaccurate positioning, but also cause safety hazards such as parts falling off. It is difficult to meet the high requirements of modern production lines for equipment stability and maintenance efficiency.

[0005] Therefore, developing a tool-free, easy-to-operate, and intuitively controllable tilting feeding device has become an important issue that urgently needs to be addressed by those skilled in the art. Utility Model Content

[0025] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art: like Figures 1 to 7 A tilting feeder that is easy to lock, comprising: The material distribution device 1 is installed on the top of the equipment via a support frame 3 and is used to receive and distribute materials.

[0026] The discharge track device 2 is installed at the bottom of the equipment via a support frame 3 and is supported below the material distribution device 1. It is used to receive the material falling into the material distribution device 2 and output it. The discharge track device 2 includes: a base 21 and a power unit 22 installed on the base 21. The discharge track 23 is installed on the top of the power unit 22.

[0027] The support frame 3, serving as the core for connection and support, includes: a first bracket 31 vertically mounted on the left and right ends of the front side of the base 21; and a second bracket 32 ​​hinged to the first bracket 31 via a transverse pivot 33. The second bracket 32 ​​is initially vertical, aligned with the first bracket 31. When maintenance or replacement of components of the lower discharge track device 1 (such as the discharge track) is required, the second bracket 32 ​​can be flipped forward around the transverse pivot 33 to a horizontal position perpendicular to the first bracket 31. Since the material distribution device 1 is fixedly connected to the second bracket 32, it is driven to flip forward. The transverse pivot 33 connects the left and right sides of the first bracket 31 near the top. A transverse locking shaft 34 is also connected between the left and right sides of the first bracket 31, parallel to the transverse pivot 33 above it.

[0028] Furthermore, a locking handle 35 is connected to the middle of the transverse locking shaft 34, which is easy for a person to grip and lift to lock or lower. After the material dispensing device is turned on, lifting the locking handle upwards will rotate the transverse locking shaft 34 to achieve locking.

[0029] The working process of the equipment in this case is as follows: In the initial state, the material distribution device 1 is in a vertical state along with the second support 32, above the discharge track device 2. The material is distributed by the material distribution device 1 to the discharge track device 2 for output. When it is necessary to maintain the inside of the material distribution device 1 or clean the discharge track device 2, the locking handle 35 is lowered to unlock it, and the second support 32 is rotated to flip forward around the horizontal axis 33 to a suitable angle. When it is necessary to switch back to the initial state of normal feeding, the second support 32 is rotated backward around the horizontal axis 33, flipped, and the locking handle 35 is raised. The second support 32 is locked to the first support 31 through the transmission of the horizontal locking shaft 34, ensuring the stability of the equipment.

[0030] As described above, this invention, based on existing technology, features a horizontal locking shaft parallel to the horizontal rotating shaft, with a locking handle easily gripped by the hand. Locking is achieved by lifting the handle upwards and unlocking by pulling it downwards. No tools are required; the entire process is a single-step operation, intuitive and efficient, reducing the workload for operators. The locking handle's engaged position can be visually confirmed by touch and sight (e.g., the feedback of the handle engaging in the positioning notch), ensuring a clear locking status and effectively preventing equipment malfunctions or safety risks caused by improper locking. Furthermore, the locking structure is compatible with the flipping action, allowing for quick locking after flipping. After maintenance, the handle can be easily unlocked and reset by reversing the operation, significantly shortening maintenance time and improving the actual operating efficiency of the equipment. This makes it suitable for applications requiring frequent changes to the discharge track.

[0031] like Figure 5 As shown, a transmission locking structure is provided between the first bracket 31 and the second bracket 32 ​​for locking the two when the locking handle 35 is lifted upwards or unlocking when the locking handle 35 is lowered downwards. The transmission locking structure includes: Cam guide groove 341: formed by machining on the outer peripheral surfaces of the left and right sides of the transverse locking shaft 34, each group is symmetrically arranged along the axis, and has a through groove structure that extends obliquely from the outside to the center of the shaft; The channel 342 has blind holes on the left and right sides of the transverse locking shaft 34 along the axial direction, and the hole diameter is clearance-fitted with the first shaft pin 36 and the second shaft pin 37. The first pin 36 and the second pin 37 are respectively inserted into the holes 342 on the left and right sides of the transverse locking shaft 34; one end of both extends to the outside of the transverse locking shaft 34, and the other end is located inside the hole 342; pin holes are opened on the outer circumferential surface of the pins for installing pins 343. Pin 343: A cylindrical pin is press-fitted into the pin hole of the shaft pin, and its exposed end extends into the cam guide groove 341 and slides with the inner wall of the guide groove; the pin 343 is used to drive the first shaft pin 36 and the second shaft pin 37 to move left and right when the transverse locking shaft 34 rotates and drives the cam guide groove 341 to rotate. Locking block 344 and locking slot 345: Locking block 344 is fixed to one end of the first shaft pin 36 and the second shaft pin 37 near the second bracket 32; Locking slot 345 is opened at the corresponding position of the second bracket 32, and its shape is adapted to the locking block 344, and is used for the locking block 344 to be locked in when the corresponding shaft pin moves outward. Alternating hole 346: Located on the first bracket 31 at the position corresponding to the locking block 344, the hole diameter is slightly larger than the maximum outer diameter of the locking block 344, allowing the locking block 344 to pass through and engage with the locking groove 345 when moving; it also serves a certain positioning function. Specifically, the cam guide groove 341 drives the shaft pin to move towards the second bracket 32 ​​via the pin 343, and the locking block 344 passes through the alternating hole 346 and engages with the locking groove 345, thus completing the locking. In practice, when locking, pulling the locking handle 35 upwards rotates the transverse locking shaft 34. The cam guide groove 341 rotates with the shaft and presses against the pin 343. The inclination angle of the groove surface is converted into axial thrust on the pin, causing the pin to slide relative to each other along the cam guide groove, pushing the first pin 36 and the second pin 37 towards the second bracket 32. Due to the inclined design of the cam guide groove, the pin pushes the pin outwards towards the second bracket, causing the locking block 344 connected to the end of the pin to engage in the slot 345, thus achieving locking. At this time, both the first and second springs are stretched. When unlocking, lowering the locking handle 35 downwards rotates the transverse locking shaft 34 in the opposite direction. The pin drives the first pin 36 and the second pin 37 to move towards the center, i.e., towards each other. With the assistance of the rebound of the first spring 38 and the second spring 39, the locking block 344 disengages from the slot 345, and the second bracket 32 ​​can be flipped after unlocking.

[0032] As described above, this design employs a combination of cam guide grooves, shaft pins, pins, locking blocks, and slots. The transmission locking structure is triggered simply by lifting / lowering the locking handle, requiring no tools. The operation is intuitive and fluid, significantly improving the efficiency of locking and unlocking after equipment flipping. Furthermore, the inclined cam guide groove efficiently converts the rotational force of the locking handle (35°) into the axial driving force of the shaft pin, minimizing force transmission loss and allowing operators to lock without applying excessive force. Simultaneously, the symmetrical design of double cam guide grooves, double shaft pins, and double locking blocks ensures that both blocks simultaneously engage with the slots during locking, resulting in even force distribution on the second support and preventing loosening or damage caused by concentrated force at a single locking point. This design is suitable for equipment operating under vibration. In addition, the transmission locking structure is integrated between the support and the transverse locking shaft, resulting in a compact layout that does not occupy additional space. The clearance hole design ensures smooth block movement, meeting the precise locking and positioning requirements after the support is flipped.

[0033] like Figure 7 As shown, the cam guide groove 341 is an open groove structure that slopes from the outside towards the center of the transverse locking shaft 34. Specifically, the cam guide groove 341 can be an open groove structure that slopes from the outside of the transverse locking shaft 34 towards the center of the shaft body and has a rounded transition in the groove wall. In this way, the obliquely extending cam guide groove can efficiently convert rotational force into axial force, and compared with a straight groove structure, the required locking / unlocking operation force is smaller, reducing the operational intensity.

[0034] like Figure 5 As shown, in a preferred embodiment, a first spring 38 is provided between the transverse locking shaft 34 and the first pin 36, and a second spring 39 is provided between the transverse locking shaft 34 and the second pin 37. During assembly, one end of the spring abuts against the bottom of the channel 342, and the other end abuts against the stepped surface of the pin; when locking, the pin moves outward to stretch the spring and store potential energy; when unlocking, the spring rebounds, causing the pin to quickly retract and assisting the transverse locking shaft 34 in resetting. The symmetrical springs provide balanced elastic force, preventing the locking shaft from tilting or jamming. Thus, this invention uses the rebound action of the first and second springs to assist the pin in resetting, ensuring that the pin can accurately return to its initial position after each unlocking, improving the stability of the locking structure. Moreover, the symmetrically arranged first spring 38 and second spring 39 provide balanced elastic force to the transverse locking shaft 34, preventing the locking shaft from tilting or jamming due to uneven force on one side, ensuring smooth operation when the locking handle 35 is turned.

[0035] like Figures 1-3 As shown in the illustration, in one specific embodiment, the material distribution device 1 includes a material distribution box 11 fixedly connected between the left and right sides of the second support 32. The top of the material distribution box 11 is connected to a hopper 12 for storing materials, and the bottom is supported by a discharge track 23 for conveying materials. The interior of the material distribution box 11 communicates with the hopper 12 to distribute materials to the discharge track 23. Thus, the material distribution box 11 and the second support 32 form a rigid connection. When maintenance of the discharge track 23 is required, flipping the second support 32 will simultaneously rotate the material distribution box 11 and the hopper 12 as a whole, without the need to disassemble any parts of the material distribution device separately, significantly shortening the preparation time before maintenance.

[0036] In one specific implementation, the support frame 3 further includes: a longitudinal support 40 connected to the left and right sides of the bottom of the second support 32 in the outer direction; a vertical third support 41 connected to the left and right sides of the longitudinal support 40 and parallel to the second support 32 in the longitudinal direction; the front sides of the left and right sides of the distribution box 11 are connected to the second support 32, and the rear sides of the left and right sides are connected to the third support 41. Thus, the distribution box 11 forms a stable support structure through a two-point connection between the front and the second support 32 and the rear sides of the third support 41, combined with the fixation of the third support 41 by the longitudinal support 40. Compared to a single-point or single-side connection, this structure can more evenly distribute the weight of the distribution box 11 and the materials inside, avoiding tilting and shaking of the distribution box due to material accumulation. It is especially suitable for high-load scenarios when the hopper 12 is full, ensuring the structural stability of the equipment during operation.

[0037] In one specific implementation, the discharge track device 2 includes a base 21, a power unit 22 mounted on the base 21, and a discharge track 23 located on top of the power unit 22. The discharge track 23 is supported below the material distribution device 1. The power unit 22 is located between the base 21 and the discharge track 23 and is used to drive the discharge track 23 to vibrate. Thus, the power unit is located between the base and the discharge track, making full use of the unused space between them, avoiding the need for additional installation area, and resulting in a more compact structure.

[0038] In one specific implementation, the first support 31 is vertically mounted on the left and right ends of the front side of the base 21. The horizontal rotating shaft 33 is connected between the left and right sides of the first support 31 near the top. The second support 32 is initially vertically aligned with the first support 31 and can be rotated forward around the horizontal rotating shaft 33 to a horizontal state perpendicular to the first support 31. Thus, by vertically mounting the first support on both ends of the front side of the base and connecting the horizontal rotating shaft to the top of the first support, while simultaneously limiting the second support to initially being vertically aligned with the first support and capable of rotating forward to a vertically horizontal state, the material distribution device can be completely moved out of the main body of the equipment after rotation, providing ample space for maintenance of the lower discharge track device. It also ensures precise docking between the material distribution device and the discharge track during initial operation, and stable equipment stress. Furthermore, the clearly defined rotation angle makes operation intuitive and controllable, reducing errors. The overall structure is compact and does not occupy additional space, balancing ease of maintenance, operational stability, ease of use, and space utilization.

[0039] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the bottom front side of the material distribution box 11 is provided with a positioning recess 111, and the locking handle 35 engages with the positioning recess 111 when it is lifted upwards. Thus, the positioning recess 111 provides a dedicated resting position for the lifted locking handle 35. Furthermore, the locking handle provides a clear "locking feel" when it engages with the positioning recess when lifted upwards, and operators can visually observe whether the handle is embedded in the recess to quickly confirm whether the locking is in place, avoiding the problem in existing technologies where loose screws are difficult to detect, and reducing potential hazards caused by operational oversights.

[0040] In a preferred embodiment, the material distribution box 11 has a discharge opening 112 on one side / rear side facing the discharge track device 2, and a scale plate 51 with height adjustment scale 5 is provided above the discharge opening 112 on this side. A height adjustment plate 52 for adjusting the gap between the scale plate 51 and the discharge track device 2 is stacked on the rear side of the scale plate 51. The scale plate 51 has one or more positioning holes 53 for height adjustment, and the height adjustment plate 52 has one or more vertical strip holes 54 for height adjustment by fixing to the positioning holes 53 with screws. Specifically, as shown... Figure 6The scales 0.0, 2.0, 4.0, and 6.0 are height adjustment scales. By adjusting the height to correspond to different scale values, the gap between the height adjustment plate 52 and the discharge track is changed to ensure that the material can pass smoothly without jamming. Different heights can also be adjusted according to different discharge products to improve the compatibility of the device.

[0041] In summary, this case discloses a locking-friendly tilting feeding device, aiming to solve the problem of existing tilting structures relying on screw locking, which is prone to hidden dangers due to loose screws. It includes a material distribution device, a discharge track device, and a support frame connecting the two. The support frame includes a first bracket vertically positioned in front of the discharge track device, and a second bracket hinged to the first bracket via a horizontal rotating shaft. The material distribution device is mounted on the second bracket and tilts with it. The first bracket has a horizontal locking shaft parallel to the horizontal rotating shaft, with a locking handle connected to the middle of the shaft to lock the tilted second bracket. The locking shaft can also be assisted by cam guide grooves, shaft pins, pins, springs, etc., for locking and unlocking. The material distribution box has a positioning notch for the handle to be engaged to confirm the locked state, and a discharge opening with a graduated adjustment structure is provided on the rear side of the material distribution box. This device requires no tools, and locking / unlocking can be completed in a single step. The locked state is intuitively identifiable, maintenance efficiency is high, and it is suitable for scenarios requiring frequent replacement of the discharge track.

[0042] As stated above, this case protects a tilting feeding device that is easy to lock, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
