Description

Technical Field

[0001] The invention relates to the technical field of ball mills, in particular to a hard alloy ball milling device for producing antenna alloy material accessories. Background Art

[0002] Antenna is a key component of signal transmission, and its performance and stability have a vital impact on the quality of communication. Alloy is a material commonly used in antenna accessories such as antenna covers. In the production process of antenna alloy accessories, it is usually necessary to use a cemented carbide ball mill for preliminary crushing to generate metal powder that meets the requirements. The cemented carbide ball mill places cemented carbide and ball milling media in the same container for running-in processing to generate cemented carbide powder particles with a certain formability and density.

[0003] The working principle of cemented carbide ball mill is to control the ratio of ball milling media and cemented carbide powder, the rotation speed of the ball milling container, the running-in time and other parameters, so that the cemented carbide powder is subjected to uniform impact and shearing during the ball milling process, thereby achieving powder refinement, mixing and homogenization. The advantage of cemented carbide ball mill is that it can efficiently and accurately control the particle size distribution and formability of cemented carbide powder, thereby meeting the requirements of cemented carbide material performance in different fields. The most commonly used ball mills usually have a horizontal cylinder structure, and the ball milling media moves with the rotation of the cylinder. Although it has a good uniform grinding effect, it often lacks the impact force on large-particle alloy materials in the initial stage of grinding, resulting in a slow initial crushing speed.

The positioning hole is provided close to the sliding seat, and the self-adjusting hole is provided close to the support rod. A pin is provided on the adjustment seat for fixing the position of the adjustment seat.

[0012] Preferably, an arc-shaped clamping plate is fixedly connected to the arc rail, and the clamping plate is arranged on the side of the arc rail, and limiting teeth are arranged on the clamping plate, and when the adjustment seat is fixed at the position of the positioning hole, the clamping seat can be connected to the adjacent limiting teeth, and the end of the support rod is provided with a wear-resistant end cap, and when the adjustment seat is fixed at the position of the self-adjusting hole, the wear-resistant end cap can be in contact and connected with the pushing column.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention has high-efficiency grinding performance. It has a floating liner block design.

[0016] 2. The present invention accumulates elastic potential energy by setting the magnetic plate as an inner liner block, and the position of the magnetic plate can be flexibly adjusted. The magnetic plate on the slide can automatically adjust its position when the cylinder rotates to adapt to the height change of the material at different rotation speeds. By adjusting the pop-up position of the inner liner block, it is ensured that the processing area of ​​the grinding medium can always be effectively saturated, thereby continuously providing the best grinding effect. At the same time, the adjustment of the magnetic plate has two modes of manual and automatic adjustment, so that the operator can adjust the position of the magnetic plate at any time according to actual needs, or make the position of the magnetic plate automatically adjusted according to the rotation speed of the cylinder. When the rotation speed of the cylinder is higher, the push column combined with the action of centrifugal force will generate greater friction, thereby prompting the slide to move upward to adapt to the height to which the material is brought, thereby ensuring stability and consistency in the processing process.

[0017] 3. The floating liner blocks of the present invention are selective. Operators can choose to operate some or all of the liner blocks in a floating state according to processing needs. This flexibility enables the equipment to process materials with different characteristics and states, such as hard alloy particles or softer materials. The grinding effect of various materials can be optimized simply by selectively controlling the floating conditions of the liner blocks. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 11 The present invention provides a technical solution: a cemented carbide ball milling device for producing antenna alloy material accessories.

[0032] like Figure 1-Figure 3 As shown, the ball milling device includes a support base 1, which is usually fixed on a stable concrete floor. A first bearing 2 and a second bearing 3 are respectively arranged on both sides of the support base 1. The cylinder 4 of the ball milling device is installed through the first bearing 2 and the second bearing 3. Both sides of the cylinder 4 are provided with hollow shafts 5 for feeding and discharging materials, and the alloy material can be fed in and out from the hollow shafts 5 for feeding and discharging materials. At the same time, a large gear is also installed on the cylinder 4, and the cylinder 4 can be driven to rotate by a driving structure such as a motor, a reducer, and a small gear. Note that the motor uses an energy-saving motor to meet the needs of continuous and long-term work to reduce costs; so that the carbide material and the ball milling medium in the cylinder 4 are ground accordingly. A lining structure is installed inside the cylinder 4 to protect the cylinder 4 and prevent the ball milling medium from causing damage to the cylinder 4.

[0033] like Figure 3-Figure 5 As shown, the lining plate structure is composed of a fixed lining plate 6 and a floating lining strip. The fixed lining plate 6 is a cylindrical structure with a notch, which is installed on the inner wall of the cylinder 4, and the lining strip is arranged in the notch of the fixed lining plate 6. The lining strip is composed of a plurality of lining blocks 9 arranged and combined. A top plate 7 is inlaid and installed on the cylinder 4, and a floating rod 8 is arranged and slidably installed on the top plate 7, and the lining block 9 is installed at the bottom end of the floating rod 8. A ferromagnetic end block 10 is fixedly installed on the top of the floating rod 8, and an elastic member is fixedly connected between the ferromagnetic end block 10 and the top plate 7. The floating rod 8 is limited by its elasticity, thereby driving the lining block 9 to protrude from the inner wall of the fixed lining plate 6 under normal circumstances. If the floating rod 8 is pulled, the elastic member can be stretched to accumulate elastic potential energy. When released, the lining block 9 is used to eject the ball milling medium thereon, thereby increasing the potential energy generated by its falling, thereby enhancing its initial grinding effect and quickly crushing large particles of powder.

[0034] like Figure 7 , Figure 8As shown, the present invention mainly generates magnetic force on the ferromagnetic end block 10 to move the floating rod 8 and the inner liner block 9. A side seat 11 is arranged on the first bearing 2, and the arc rail 12 is installed through the side seat 11. A slide seat 13 is movably installed in the arc rail 12, and the slide seat 13 can move along the direction of the arc rail 12. A rotating frame 14 is fixedly connected to the slide seat 13, and a magnetic attraction plate 15 is installed through the rotating frame 14. The magnetic attraction plate 15 is located on the side of the cylinder 4. When the cylinder 4 rotates, the top plate 7 moves from When the side of the magnetic attraction plate 15 passes by, the magnetic attraction plate 15 can generate a magnetic force acting on the ferromagnetic end block 10, thereby lifting the floating rod 8 and the inner lining plate. The magnetic attraction plate 15 can adopt an electromagnetic structure or a permanent magnet structure, and a shielding plate 16 of ferromagnetic material is installed on one side of the magnetic attraction plate 15 to shield the unilateral magnetic force of the magnetic attraction plate 15, so that after the floating rod 8 passes through the shielding plate 16, it can quickly get rid of the influence of the magnetic force, thereby rebounding under the action of elastic potential energy, and using the inner lining block 9 to push the ball milling medium.

[0035] like Figure 9-10 As shown, further, since the magnetic plate 15 is installed on the slide 13 through the rotating frame 14, the position of the magnetic plate 15 can be adjusted by rotating the slide 13, thereby changing the pop-up position of the lining plate. This is because when the cylinder 4 rotates at different speeds, the materials and ball milling media inside it will be driven to different heights, so the position of the magnetic plate 15 needs to be changed accordingly. In addition to installing the rotating frame 14, the slide 13 is also provided with a mounting seat 17, and a limiting groove 18 is provided on the mounting seat 17, and the adjustment seat 22 is installed through the limiting groove 18. A clamping seat 24 is installed on one side of the adjustment seat 22, and a support rod 25 is installed on the other side, and the wear-resistant end 26 is installed through the support rod 25. An adjustment hole 19 is provided in the middle of the limiting groove 18, and a positioning hole 20 and a self-adjusting hole 21 are provided on both sides. The positioning hole 20 is arranged close to the slide 13, and the self-adjusting hole 21 is arranged close to the support rod 25. A pin 23 is provided on the adjustment seat 22, and the pin 23 can be connected with the adjustment hole 19, the positioning hole 20 or the self-adjusting hole 21, so as to fix the adjustment seat 22 in the middle or on the left and right sides of the limiting groove 18.

[0036] like Fig.11As shown, a clamping plate 27 is fixedly connected to the arc rail 12 of the present invention. The clamping plate 27 is also an arc-shaped structure and is arranged on the side of the arc rail 12. Limit teeth 28 are arranged on the clamping plate 27. At the same time, an annular groove 29 is fixedly connected to the feeding and discharging hollow shaft 5 on the side close to the first bearing 2, and a pushing column 30 is arranged in an annular array on the outer wall of the annular groove 29. The annular groove 29 can rotate with the feeding and discharging hollow shaft 5. The pushing column 30 adopts a movable structure and its surface has friction. When the adjusting seat 22 is fixed in the middle of the limiting groove 18 by the latch 23, the clamping seat 24 will not be connected with the limiting teeth 28, and the wear-resistant end head 26 will not contact with the pushing column 30. Therefore, the sliding seat 13 can move freely in the arc rail 12 to adjust the position of the magnetic suction plate 15. After the adjustment is completed, the adjusting seat 22 moves in the limiting groove 18, the latch 23 is connected to the positioning hole 20, and the clamping seat 24 The adjusting seat 22 can be manually adjusted according to the rotation speed of the cylinder 4. At the same time, the magnetic plate 15 can also be automatically adjusted as the rotation speed of the cylinder 4 changes, so that the adjusting seat 22 is moved to the position of the self-adjusting hole 21 in the limiting groove 18. At this time, the wear-resistant end 26 of the support rod 25 contacts the pushing column 30, and the annular groove 29 is pushed up by the friction force during the rotation of the hollow shaft 5 for feeding and discharging, so that the position of the slide 13 can be changed until its gravity and friction force are balanced. As the rotation speed of the cylinder 4 increases, the centrifugal force on the pushing column 30 increases, which can generate a greater positive pressure on the wear-resistant end 26, and then generate a greater friction force, so that the slide 13 rotates to a higher height to adapt to the height to which the ball mill medium is driven.

[0037] like Figure 6 As shown, at the same time, the present invention can also selectively adjust the liner block 9, so that part or all of the liner block 9 can float and pop out to push the ball milling medium down. A rotating rod 31 is rotatably installed on the top plate 7, and a stopper 32 is arranged on the top of the rotating rod 31. When the rotating rod 31 rotates the stopper 32 to the top of the ferromagnetic end block 10, the ferromagnetic end block 10 can be blocked to prevent it from lifting the floating rod 8 under the action of magnetic force. The rotating rod 31 is arranged on the side of the floating rod 8. Half of the rotating rod 31 can be arranged on one side of the floating rod 8, and the other half can be arranged on the other side of the floating rod 8. Figure 3As shown, the bottom of the rotating rod 31 is fixedly connected to the gear 33, and the upper limit sliding installation of the top plate 7 is provided with a control end 34, and the control end 34 is fixedly connected to the moving rod 35, and the moving rod 35 is arranged with a rack 36. Accordingly, the moving rod 35 can be respectively arranged on both sides of the floating rod 8, and the rack 36 thereon is connected with half of the gear 33. When the control end 34 is moved, half of the rotating rod 31 can be rotated, and the stopper 32 is blocked on the ferromagnetic end, so that the lining block 9 at this position will not move, so half of the lining block 9 can be selected to play the medium ejection work. Correspondingly, it is also possible to select to divide the floating rod 8 and the lining block 9 into more parts and control them separately. In addition, a card slot is provided on the control end 34, and a center seat 37 is fixedly installed on the top plate 7, and a spring card block 38 is provided on the center seat 37. The control end 34 is fixed in the corresponding position by connecting the spring card block 38 with the card slot, so as to achieve the effect of stabilizing the control block 32 and selecting the lining block 9 to be used.
