Description

Technical Field

[0001] This utility model relates to the field of bar polishing technology, and in particular to a high-speed bar polishing machine. Background Technology

[0002] The existing bar polishing equipment has the following processing steps: The operator puts the bar into the polishing bucket and manually presses the equipment start button. The polishing machine then begins to polish the bar. The polishing principle is that the polishing bucket vibrates up and down at a high frequency, causing high-frequency vibration and friction between the bars, which gradually removes the burrs and protrusions on the cylindrical surface of the bar.

[0003] However, this kind of physical friction polishing between bars requires each bar to be relatively straight and regular. When a part of a pile of materials is not very regular, some of the polished bars will have residual burrs that cannot be removed.

[0004] Meanwhile, traditional machines involve manual feeding and polishing, followed by manual unloading. For existing bar polishing technology in the equipment manufacturing industry, older bar polishing machines suffer from several drawbacks: they cannot completely remove burrs from the cylindrical surface of the bar during polishing; removing semi-finished bars after polishing is inconvenient; and traditional polishing hoppers can only have a fixed width, making it impossible to adjust the hopper width according to the size of the bar.

[0005] Therefore, in order to solve the problems existing in the above-mentioned technologies, there is an urgent need for a high-speed polishing machine for bar stock. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-speed polishing machine for bar stock.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A high-speed polishing machine for bar stock includes a support frame, a hopper seat plate slidably connected to the top outer wall of the support frame, a stirring polishing box fixed to the top outer wall of the support frame, a motor fixed to the top outer wall of the stirring polishing box, a first drive shaft and multiple driven shafts rotatably connected to one side outer wall of the stirring polishing box, a pulley fixed to the outer wall of the first drive shaft, the pulley being connected to the output shaft of the motor via a drive belt, a drive gear meshing with each other fixed to the outer walls of the first drive shaft and the driven shafts, and polishing wheels fixed to the outer walls of the first drive shaft and the driven shafts respectively;

[0009] A swing plate is fixed to the bottom outer wall of the hopper seat plate. A swing arm is rotatably connected to one side of the outer wall of the swing plate. A second drive shaft is rotatably connected to the outer wall of the support frame through a bearing seat. A sprocket is fixed to the outer wall of the second drive shaft. The sprocket is connected to the first drive shaft through a drive chain. An eccentric clamp is fixed to one end of the sprocket. One end of the eccentric clamp is rotatably connected to one side of the outer wall of the swing arm.

[0010] As a further embodiment of this utility model: the top outer wall of the support frame is slidably connected to a second side bracket and a first side bracket, and the top outer wall of the support frame is rotatably connected to a set of positive and negative threaded screws through a bearing seat. The outer walls of the positive and negative threaded screws are respectively connected to a first internal threaded sleeve and a second internal threaded sleeve through threads. The first internal threaded sleeve is fixed to one side outer wall of the first side bracket through a fixing plate, and the second internal threaded sleeve is fixed to one side outer wall of the second side bracket through a fixing plate. An adjustment handle is inserted into one end of the positive and negative threaded screws.

[0011] As a further improvement of this utility model: multiple pushing angle plates are fixed to the top outer wall of the hopper seat plate, and a partition is fixed to one side outer wall of the first side baffle.

[0012] As a further embodiment of this utility model: a reinforcing frame is fixed to the outer wall of the top of the support frame with copper drum screws, an adjusting plate is fixed to the outer wall of the reinforcing frame, and a feed baffle is slidably connected to the inner wall of the adjusting plate.

[0013] As a further improvement of this utility model: a guide plate is fixed to the outer wall of the first side bracket, and one side outer wall of the second side bracket is slidably connected to the inner wall of the guide plate.

[0014] As a further improvement of this utility model: a side baffle is fixed to the outer wall of the support frame, a gate is slidably connected to one side of the outer wall of the agitation and polishing box, and a discharge port is fixed to one end of the hopper seat plate.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. When the first drive shaft rotates, it drives the drive gear on the outer wall to rotate. The four sets of drive gears mesh with each other and rotate in different directions in sequence. Each set of drive gears drives a set of polishing wheels to rotate. When the polishing wheels rotate, they agitate the bar material entering the agitation and polishing box, achieving the effect of polishing the bar material around its entire circumference. In this embodiment, four sets of driven gears mesh with each other for transmission. The direction of rotation of each set of polishing wheels is the same as that of the driven gears. This function enables the bar material to be polished in both clockwise and counterclockwise directions, and can also remove finer burrs.

[0017] 2. In this embodiment, two sets of positive and negative threaded screws are used to adjust the width between the first side stop and the second side stop. This function can adjust the width according to the specifications of the bar stock. The adjustment can be made by turning the adjustment handle. After the adjustment is completed, the adjustment handle can be pulled out and placed in the toolbox, so that the polishing machine can polish bars of different sizes, thus improving the applicability of the polishing machine.

[0018] 3. After the bar stock has been polished repeatedly within the steel wheel agitation mechanism for a limited time, the operator only needs to open the discharge gate. The polished bar stock will automatically flow out of the equipment and directly into the rubber frame or connect with the next automated equipment. The entire machine can be manually or automatically fed, and then discharged from the other side, thereby achieving continuous production and improving the automation process.

[0019] 4. This equipment uses only one motor to drive all the moving mechanisms, which simplifies the complicated motion programming and minimizes concerns about after-sales maintenance.

[0020] 5. Polishing wheels can be made into different shapes depending on the bar stock. For example, they can be cam-shaped, elliptical, triangular, quadrilateral, gear-shaped, or other irregular shapes. The material of the polishing wheels is not limited to a certain material. Furthermore, this structure is not limited to four sets of polishing wheels; depending on the characteristics of the bar stock, one, two, three, four, five, six, or even more sets of polishing wheels can be used. The number of polishing wheels, the direction of rotation, the material, and the shape of the polishing and agitating mechanism are all unrestricted.

[0021] 6. The main industries applicable to this utility model are disposable round bamboo chopsticks, disposable square bamboo chopsticks, household bamboo and wooden chopsticks, bamboo toothpicks, bamboo barbecue skewers, bamboo cotton swabs, and bamboo incense sticks. The thickness and length of the above products are not limited. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0029] Example 1

[0030] High-speed polishing machine for bar stock, such as Figure 1-4 As shown, the device includes a support frame 1, a hopper seat plate 29 slidably connected to the top outer wall of the support frame 1, an agitator and polishing box 25 fixed to the top outer wall of the support frame 1, a motor 9 fixed to the top outer wall of the agitator and polishing box 25, a first drive shaft 26 and multiple driven shafts 4 rotatably connected to one side outer wall of the agitator and polishing box 25, a pulley 23 fixed to the outer wall of the first drive shaft 26, the pulley 23 being connected to the output shaft of the motor 9 via a drive belt, a drive gear 27 meshing with each other fixed to the outer walls of the first drive shaft 26 and the driven shafts 4, and polishing wheels 30 fixed to the outer walls of the first drive shaft 26 and the driven shafts 4 respectively.

[0031] A swing plate 19 is fixed to the bottom outer wall of the hopper seat plate 29. A swing arm 20 is rotatably connected to one side of the outer wall of the swing plate 19. A second drive shaft 21 is rotatably connected to the outer wall of the support frame 1 through a bearing seat. A sprocket 22 is fixed to the outer wall of the second drive shaft 21. The sprocket 22 is connected to the first drive shaft 26 through a drive chain. An eccentric clamp 31 is fixed to one end of the sprocket 22. One end of the eccentric clamp 31 is rotatably connected to one side of the outer wall of the swing arm 20.

[0032] The support frame 1 has a second side baffle 13 and a first side baffle 14 slidably connected to its top outer wall. The support frame 1 has a set of positive and negative threaded screws 16 rotatably connected to its top outer wall via a bearing seat. The outer walls of the positive and negative threaded screws 16 are respectively connected to a first internal threaded sleeve 5 and a second internal threaded sleeve 17 via threads. The first internal threaded sleeve 5 is fixed to one side outer wall of the first side baffle 14 via a fixing plate 15. The second internal threaded sleeve 17 is fixed to one side outer wall of the second side baffle 13 via a fixing plate 15. An adjusting handle 18 is inserted into one end of the positive and negative threaded screws 16.

[0033] The top outer wall of the hopper seat plate 29 is fixed with multiple pushing angle plates 28, and the outer wall of one side of the first side baffle 14 is fixed with a partition plate 3.

[0034] The support frame 1 is fixed to the outer wall of the top with copper drum screws and a reinforcing frame 2. The outer wall of the reinforcing frame 2 is fixed with an adjusting plate 10 and the inner wall of the adjusting plate 10 is slidably connected with a feed baffle 12.

[0035] The outer wall of the first side baffle 14 is fixed with a guide plate 11, and one side outer wall of the second side baffle 13 is slidably connected to the inner wall of the guide plate 11.

[0036] The outer wall of the support frame 1 is fixed with a side baffle 8, and a gate 7 is slidably connected to one side of the outer wall of the agitation and polishing box 25. A discharge port 6 is fixed at one end of the hopper seat plate 29.

[0037] When the polishing machine is running, the operator first places the bar to be polished on top of the hopper seat plate 29. The motor 9 drives the pulley 23 to rotate via the transmission belt, which in turn drives the first transmission shaft 26 to rotate. When the first transmission shaft 26 rotates, it drives the sprocket 22 to rotate via the transmission chain, which in turn drives the eccentric clamp 31 at one end of the second transmission shaft 21 to rotate. When the eccentric clamp 31 rotates, it pushes the swing plate 19 to move back and forth via the swing arm 20 connected to one end, which in turn drives the hopper seat plate 29 to reciprocate back and forth. The bar moves back and forth at high frequency in the hopper, causing the bar on the top of the hopper seat plate 29 to rub against each other, which can polish burrs. The push angle plate 28 pushes the bar forward in the high-frequency reciprocating motion, so that the bar that has been initially polished by friction passes through the feed baffle 12 and enters the agitation and polishing box 25.

[0038] When the first drive shaft 26 rotates, it drives the drive gear 27 on the outer wall to rotate. The four sets of drive gears 27 mesh with each other and rotate in different directions in sequence. Each set of drive gears 27 drives a set of polishing wheels 30 to rotate. When the polishing wheels 30 rotate, they agitate the bar material entering the agitation and polishing box 25, achieving the effect of polishing the bar material around its entire circumference. In this embodiment, four sets of driven gears 24 mesh with each other for transmission. The direction of rotation of each set of polishing wheels 30 is the same as that of the driven gears 24. This function enables the bar material to be polished in both clockwise and counterclockwise directions, and can also remove finer burrs.

[0039] The polishing wheel 30 can be made into different shapes depending on the bar stock. For example, its shape can be cam-shaped, elliptical, triangular, quadrilateral, gear-shaped, or other irregular shapes. The material of the polishing wheel 30 is not limited to a certain material. At the same time, this structure is not limited to four sets of polishing wheels. Depending on the characteristics of the bar stock, one, two, three, four, five, six, or even more sets of polishing wheels 30 can be used. The number of polishing wheels 30, the direction of agitation, the material, and the shape of the polishing and agitation mechanism are not limited.

[0040] The size of the bar stock feed inlet can be adjusted as needed. If it is increased, the feed baffle 12 is adjusted upwards; if it is decreased, the feed baffle 12 is adjusted downwards. After the bar stock runs in the agitation and polishing box 25 for a limited time, the polishing is completed. The gate 7 can be manually pulled upwards, and the bar stock will automatically shake and discharge. The material can then be collected with a plastic frame.

[0041] In this embodiment, two sets of positive and negative threaded screws 16 are used to adjust the width between the first side guard 14 and the second side guard 13. This function can adjust the width according to the specifications of the bar stock. The adjustment can be made by rotating the adjustment handle 18. After the adjustment is completed, the adjustment handle 18 can be pulled out and placed in the toolbox, so that the polishing machine can polish bars of different sizes, thus improving the applicability of the polishing machine.

[0042] This equipment features conventional physical high-frequency vibration polishing. After high-frequency polishing, the bar stock automatically flows into the next station's steel wheel agitation polishing mechanism for further polishing. In this embodiment, the steel wheel agitation mechanism is designed with four sets of steel wheels, which are driven by gears. The four sets of steel wheels rotate clockwise, counterclockwise, clockwise, and counterclockwise, respectively, so that the burrs on the surface of the bar stock are repeatedly agitated clockwise and counterclockwise, forcibly removing the burrs from the surface of the bar stock.

[0043] After the bar stock has been polished repeatedly within the steel wheel agitation mechanism for a limited time, the operator only needs to open the discharge gate. The polished bar stock will automatically flow out of the equipment and directly into the rubber frame or connect with the next automated equipment. The entire machine can be manually or automatically fed, and then discharged from the other side, thus achieving continuous production and improving the automation process.

[0044] This utility model is mainly applicable to the following industries: disposable round bamboo chopsticks, disposable square bamboo chopsticks, household bamboo and wooden chopsticks, bamboo toothpicks, bamboo barbecue skewers, bamboo cotton swabs, and bamboo incense sticks. The thickness and length of the above products are not limited.

[0045] Working principle: When the polishing machine is running, the operator first places the bar to be polished on the top of the hopper seat plate 29. The motor 9 drives the pulley 23 to rotate through the transmission belt, which in turn drives the first transmission shaft 26 to rotate. When the first transmission shaft 26 rotates, it drives the sprocket 22 to rotate through the transmission chain, which in turn drives the eccentric clamp 31 at one end of the second transmission shaft 21 to rotate. When the eccentric clamp 31 rotates, it pushes the swing plate 19 to move back and forth through the swing arm 20 connected to one end, which in turn drives the hopper seat plate 29 to reciprocate back and forth. The bar moves back and forth at high frequency in the hopper, causing the bar on the top of the hopper seat plate 29 to rub against each other, which can polish burrs. The push angle plate 28 pushes the bar forward in the high-frequency reciprocating motion, so that the bar that has been initially polished by friction passes through the feed baffle 12 and enters the agitation and polishing box 25.

[0046] When the first drive shaft 26 rotates, it drives the drive gear 27 on the outer wall to rotate. The four sets of drive gears 27 mesh with each other and rotate in different directions in sequence. Each set of drive gears 27 drives a set of polishing wheels 30 to rotate. When the polishing wheels 30 rotate, they agitate the bar stock entering the agitation and polishing box 25, achieving the effect of polishing the bar stock around its entire circumference. The size of the bar stock inlet can be adjusted as needed. If it is enlarged, the inlet baffle 12 is raised; if it is enlarged, the inlet baffle 12 is lowered. After the bar stock has been running in the agitation and polishing box 25 for a limited time, the polishing is completed. The gate 7 can be manually pulled up, and the bar stock will automatically shake and be discharged. The bar stock can then be collected with a plastic frame.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
