Description

Technical Field

[0001] This invention relates to the field of umbrella processing equipment technology, and in particular to an umbrella rib chamfering machine. Background Technology

[0002] With the development of technology, umbrellas have also changed, from the old oil-paper umbrellas to umbrellas with a wide variety of styles. The umbrella ribs are the individual frames that support the umbrella. In the past, most umbrella ribs were made of wood or bamboo. Later, as the umbrella canopy changed, the umbrella ribs also changed. While the ribs used to be mostly made of wood or bamboo, iron ribs, steel ribs, aluminum alloy ribs, fiber ribs, electroplated ribs, and resin ribs appeared. Most of them use retractable ribs (contractable umbrellas), making them lightweight and convenient to carry.

[0003] Steel frames are the strongest and most durable, not easily broken, and have a long service life. Iron frames are hard and not easily broken, and have good wind resistance, but they are prone to rusting over time. Aluminum, electroplated, and resin frames are relatively lightweight and portable, and are commonly used in lightweight umbrellas.

[0004] In the actual manufacturing of umbrellas, the ribs need to be cut into multiple sections and then assembled together. To prevent the cut edges of the ribs from scratching people, the cut edges need to be polished.

[0005] Currently, Chinese patent CN114367895A discloses an automated polishing machine for umbrella processing, including: a worktable, a support member above the worktable, an adjustment mechanism for adjusting the height of the support member around its periphery, a bidirectional polishing mechanism for simultaneously polishing both ends of the umbrella ribs on the front side of the adjustment mechanism, and a clamping mechanism around the bidirectional polishing mechanism.

[0006] This type of automated umbrella rib grinding machine avoids unstable clamping and the drawbacks caused by adjusting the grinding end of the umbrella rib. However, since this grinding machine can only manually feed the umbrella rib, the operator needs to place the umbrella rib on the operating table one by one, start the grinding wheel, and then stop the machine to unload the rib manually. Both loading and unloading require stopping the machine, resulting in a low overall level of mechanization and automation and low production efficiency. Summary of the Invention

[0007] This invention addresses the aforementioned technical problems and overcomes the shortcomings of existing technologies by providing an umbrella rib beveling machine.

[0008] To solve the above technical problems, the present invention provides an umbrella rib chamfering machine.

[0009] Technical benefits: The disc-shaped automatic feeding unit can sequentially clamp the umbrella ribs onto the feeding turntable, which then conveys the ribs to the grinding wheel. After grinding, the ribs can be automatically unloaded sequentially. The circumferential feeding method avoids the need to stop the machine during loading and unloading. The overall processing is highly continuous, with a high degree of automation and high production efficiency. At the same time, the feeding tray and the automatic feeding unit are linked to each other, ensuring the consistency of the loading, grinding and unloading rates.

[0010] The technical solution further defined by the present invention is: an umbrella rib chamfering machine, comprising a machine body, a grinding component inside the machine body, an automatic feeding component on one side of the machine body, an automatic unloading component on the other side, and an intermediate transmission component at the center of the machine body for sequentially conveying the umbrella ribs from the automatic feeding component to the grinding component and the automatic unloading component. The intermediate transmission component includes a rotating shaft rotatably connected to the center of the machine body perpendicular to the horizontal plane. Two identical and parallel feeding turntables are fixed on the rotating shaft. Several locking teeth are integrally formed on the side of the feeding turntables, which are arranged around the rotating shaft. The size of the locking teeth is adapted to the umbrella ribs and used to lock the umbrella ribs. The automatic feeding component, the grinding component, and the automatic unloading component are all located on the circumference of the feeding turntables. A drive component is provided inside the machine body for driving the rotating shaft to rotate synchronously with the automatic feeding component.

[0011] Furthermore, the automatic feeding component includes a feeding frame, which includes a top plate and a bottom plate that are parallel to each other. A push plate is slidably connected between the top plate and the bottom plate. The push plate includes a pressure plate that is tangent to the outer circle of the feeding turntable, and an active plate that is slidably connected to the top plate and the bottom plate at both ends respectively. The active plate is inclined relative to the pressure plate.

[0012] The aforementioned umbrella rib chamfering machine has parallel sliding grooves on the top and bottom plates. The top and bottom of the active plate are slidably connected in the two sliding grooves. An adjusting shaft is rotatably connected inside the machine body. A connecting rod is provided between one side of the active plate and the adjusting shaft. One end of the connecting rod is hinged to the active plate, and the other end is rotatably connected to the end of the adjusting shaft.

[0013] The aforementioned umbrella rib chamfering machine has several parallel stabilizing plates on the pressure plate. The automatic feeding component includes a feeding frame, which forms a cavity for receiving finished products. A picking plate is provided on one side of the feeding frame. The picking plate is inclined relative to the inner side of the feeding frame, and one side of the picking plate is attached to the outer circle of the feeding turntable.

[0014] The aforementioned umbrella rib chamfering machine includes a grinding assembly consisting of a grinding seat located above the feeding turntable. A grinding wheel is rotatably connected to the grinding seat via a drive shaft. A drive motor is fixed on one side of the machine body. Both the output shaft of the drive motor and the end of the drive shaft are equipped with synchronous pulleys. The two synchronous pulleys are driven by a synchronous belt. An exhaust fan with an opening facing the bottom of the grinding wheel is provided on the machine body.

[0015] The aforementioned umbrella rib chamfering machine has an auxiliary stabilizing component inside the machine body, which is used to press the umbrella rib to stabilize its position during umbrella rib grinding. The auxiliary stabilizing component includes a stabilizing seat fixed inside the machine body, and a stabilizing belt is provided on the stabilizing seat. The stabilizing belt is located between two feeding turntables and is used to cooperate with the two feeding turntables to press the umbrella rib. The stabilizing belt is sequentially wound around several stabilizing wheels that are rotatably connected to the stabilizing seat.

[0016] The aforementioned umbrella rib chamfering machine includes three stabilizing wheels connected to the stabilizing seat in an isosceles triangle configuration. The longest side of the stabilizing belt is attached to the side of the feeding turntable. A pressure wheel is located in the middle of the longest side of the stabilizing belt on the stabilizing seat. There are two parallel pressure wheels. A central shaft is located on the center line of the stabilizing wheel on one side of the stabilizing seat, which is used to connect the driving component to drive the entire auxiliary stabilizing component to rotate.

[0017] The aforementioned umbrella rib beveling machine includes a drive motor and a reducer fixed inside the machine body. The drive motor and the reducer are driven by a synchronous belt. The output shaft of the reducer is equipped with an output wheel and a sprocket arranged coaxially. The sprocket is driven by a transmission chain to the central shaft.

[0018] The aforementioned umbrella rib chamfering machine has an intermediate shaft inside the machine body. One end of the intermediate shaft is connected to the output wheel via a synchronous belt, and the other end is connected to the automatic feeding component via a synchronous belt. A balance disc is fixed coaxially at the bottom of the rotating shaft.

[0019] The beneficial effects of this invention are:

[0020] (1) In this invention, after the umbrella rib enters the automatic feeding component of the machine body vertically and horizontally, the push plate therein drives the pressure plate to press the umbrella rib onto the cleat on the side of the feeding turntable. The rotating shaft rotates under the drive of the drive component, and the feeding turntable drives the umbrella rib to rotate to the bottom of the grinding component. After the end of the umbrella rib is ground to a qualified state by the grinding component, the feeding turntable continues to rotate to the position of the automatic unloading component. The processed umbrella rib can be removed and stored in the cavity by the picking plate in the automatic unloading component, thereby realizing the automation of the umbrella rib grinding operation. The two feeding turntables that are parallel to each other can ensure the firmness of the umbrella rib in the cleat, thereby improving the stability of the umbrella rib during the grinding process. The exhaust fan in the machine body can remove the waste generated during the umbrella rib grinding process. The auxiliary stabilizing component can work with the two feeding turntables to press the umbrella rib, avoid the umbrella rib from shaking during the processing, improve the grinding effect, and increase the yield.

[0021] (2) In this invention, when feeding, the umbrella ribs are placed in the automatic feeding unit. At this time, the driving unit drives the adjusting shaft to rotate through the synchronous belt. The rotation of the adjusting shaft can drive the connecting rod to push back and forth, thereby driving the active plate at the end of the connecting rod to slide along the sliding groove. During the reciprocating sliding process, the umbrella ribs can be intermittently pressed into the teeth of the feeding turntable to achieve automatic feeding.

[0022] (3) In this invention, the active motor installed in the machine body drives the synchronous belt to move, thereby linking the synchronous wheel at the end of the active shaft to rotate, which in turn links the entire active shaft and the grinding wheel to rotate, thus completing the grinding operation of the umbrella rib. The stabilizing belt of the auxiliary stabilizer can adhere to the umbrella rib after the umbrella rib rotates to a certain angle. Since the stabilizing belt is located between the two feeding turntables, the stabilizing belt adhering to the umbrella rib can ensure its stability and avoid the shaking that occurs during the grinding process.

[0023] (4) In this invention, since a pressure wheel is provided, the pressure on the entire umbrella rib is the greatest when the umbrella rib rotates to the grinding position, which can ensure the stability of the umbrella rib. At the same time, since the drive component drives the automatic feeding component and the auxiliary stabilizing component through the output wheel and the sprocket respectively, the feeding speed and the grinding speed can be matched. Here, it is possible to directly add a linkage component between the reducer and the rotating shaft to drive the feeding turntable to rotate, or it is possible to drive the movement of the stabilizing belt and use the friction generated between the stabilizing belt and the umbrella rib to drive the umbrella rib and the feeding turntable to rotate as a whole, which can make the grinding effect better.

[0024] (5) In this invention, the disc-shaped automatic feeding component can sequentially clamp the umbrella ribs onto the feeding turntable, and the feeding turntable sequentially conveys the umbrella ribs to the grinding wheel position. After grinding is completed, the ribs can be automatically unloaded sequentially. The circular feeding method can avoid stopping the machine during loading and unloading. The overall processing is highly continuous, the degree of automation is high, and the production efficiency is high. At the same time, the feeding tray and the automatic feeding component are linked to each other, ensuring the consistency of the loading, grinding and unloading rates. Attached Figure Description

The automatic feeding component includes a feeding frame 41, and a cavity 43 for receiving finished products is formed inside the feeding frame 41. A picking plate 42 is provided on one side of the feeding frame 41. The picking plate 42 is inclined relative to the inner side of the feeding frame 41, and one side of the picking plate 42 is attached to the outer circle of the feeding turntable 52.

[0036] like Figure 3-5 As shown, the grinding assembly 3 includes a grinding seat 31 located above the feeding turntable 52. A grinding wheel 32 is rotatably connected inside the grinding seat 31 via a drive shaft 36. A drive motor 33 is fixed on one side inside the machine body 1. Both the output shaft of the drive motor 33 and the end of the drive shaft 36 are provided with synchronous pulleys 34. The two synchronous pulleys 34 are driven by a synchronous belt 35. A blower 11 with an opening facing the bottom of the grinding wheel 32 is provided on the machine body 1.

[0037] like Figure 3-5 As shown, the machine body 1 is provided with an auxiliary stabilizing component 7, which is used to press the umbrella ribs to stabilize their position during the grinding of the umbrella ribs. The auxiliary stabilizing component 7 includes a stabilizing seat 71 fixed inside the machine body 1. The stabilizing seat 71 is provided with a stabilizing belt 72. The stabilizing belt 72 is located between two feeding turntables 52 and is used to cooperate with the two feeding turntables 52 to press the umbrella ribs. The stabilizing belt 72 is sequentially wound around a number of stabilizing wheels 73 that are rotatably connected to the stabilizing seat 71.

[0038] like Figure 3-5 As shown, the stabilizing wheel 73 includes three isosceles triangles connected to the stabilizing seat 71. The longest side of the stabilizing belt 72 is attached to the side of the feeding turntable 52. A pressure wheel 74 is provided on the stabilizing seat 71 at the middle position of the longest side of the stabilizing belt 72. There are two parallel pressure wheels 74. A central shaft 75 is provided on the center line of the stabilizing wheel 73 on one side of the stabilizing seat 71, which is used to connect the driving component 6 to drive the entire auxiliary stabilizing component 7 to rotate.

A balance disc 54 is fixed coaxially at the bottom of the rotating shaft 51.

[0040] The working process is as follows: After the umbrella rib enters the automatic feeding component 2 of the machine body 1 vertically and horizontally, the push plate 24 drives the pressure plate 241 to press the umbrella rib onto the cleat 53 on the side of the feeding turntable 52. The rotating shaft 51 rotates under the drive of the drive component 6, and the feeding turntable 52 drives the umbrella rib to rotate to below the grinding component 3. After the grinding component 3 grinds the end of the umbrella rib to a qualified state, the feeding turntable 52 continues to rotate to the position of the automatic unloading component 4. The processed umbrella rib is then removed by the picking plate 42 inside the automatic unloading component 4. After completion, the umbrella ribs are removed and housed in the cavity 43, thus automating the umbrella rib grinding operation. The two parallel feeding turntables 52 ensure the umbrella ribs are firmly secured in the clamping teeth 53, thereby improving the stability of the umbrella ribs during the grinding process. The exhaust fan 11 installed inside the machine body 1 can remove the waste generated during the umbrella rib grinding process. The auxiliary stabilizing component 7 works with the two feeding turntables 52 to press the umbrella ribs together, preventing the umbrella ribs from shaking during processing and improving the grinding effect.

[0041] In this invention, the disc-shaped automatic feeding component 2 can sequentially clamp the umbrella ribs onto the feeding turntable 52, and the feeding turntable 52 sequentially conveys the umbrella ribs to the grinding wheel 32. After grinding, the ribs can be automatically unloaded sequentially. The circumferential feeding method can avoid stopping the machine during loading and unloading. The overall processing is highly continuous, with a high degree of automation and high production efficiency. At the same time, the feeding tray and the automatic feeding component 2 are linked to each other, ensuring the consistency of the loading, grinding and unloading rates.
