Description

Technical Field

[0001] The utility model relates to the technical field of ultramicro pulverizers, in particular to a vacuum feeding device for an ultramicro pulverizer. Background Art

[0002] An ultramicro pulverizer is a device that uses air separation, heavy pressure grinding, and shearing to achieve ultrafine pulverization of dry materials. In modern industrial production, the use of ultramicro pulverizers is very common. The vacuum feeder used for feeding when an ultramicro pulverizer is in use is a device that generates vacuum to transport powder and granular materials through a vacuum pump. In the process of using the existing vacuum feeder, due to the excessive height of the discharge port, users often place a cushion block at the bottom of the discharge port and then place the receiving barrel on the cushion block. This results in the inability of the discharge port to be docked with the receiving barrel, and thus the transported materials will be scattered onto the ground, which is a waste. If a hose is connected, manual support is required, and without a cushion block, the collection process will be more cumbersome. If a hose is connected for collection, manual support is required all the time, which is too troublesome. Without a cushion block to support the receiving barrel, the collection process will be more cumbersome, time-consuming, and laborious.

The sealing ring can prevent dust from entering through the gap. The movable device can move the positioning device out of the inside of the fixed block to achieve height adjustment, and has the advantages of adjusting the length of the discharge port, achieving support for the receiving barrel without using a cushion block, and preventing the materials from being scattered onto the ground, resulting in a better collection effect.

[0004] However, in the above method, it is necessary for the staff to manually press the pressure bar downward to drive the positioning block out of the inside of the positioning groove, and continuously press the pressure bar to adjust the height of the movable block, resulting in a relatively high labor intensity for the staff.

The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0021] The first embodiment of this application is as follows:

[0022] Please refer to Figures 1 to 4 , where Figure 1 is the structural schematic diagram of the first embodiment of the present utility model, Figure 2 is the partial structural schematic diagram of the first embodiment of the present utility model, Figure 3 is the local structural schematic diagram of the first embodiment of the present utility model, Figure 4 is the structural schematic diagram of the positioning slot of the present utility model.

[0023] The present utility model provides a vacuum feeding device for an ultrafine pulverizer, including a vacuum feeding machine 101, a fixed block 102, a movable block 103 and a positioning mechanism. The positioning mechanism includes a frame 104, a mounting plate 105, a motor 106, an oval plate 107, two slide plates 108, two connecting members, two plug rods 109, two seals 110, a spring 111, a hollow rod 112, a rod body 113 and a bolt 114. The connecting members include a connecting rod 115 and a connecting block 116. The foregoing solution solves the technical problem in the prior art that it is necessary for workers to manually press the pressure rod downward to drive the positioning block to move out of the inside of the positioning slot 120, and continuously press the pressure rod to adjust the height of the movable block 103, resulting in a relatively high labor intensity for the workers.

[0024] For this specific implementation manner, a discharge port 117 is provided on the vacuum feeding machine 101, and the fixed block 102 is fixedly connected to the discharge port 117. When specifically used, the discharge port 117 is used for discharging the vacuum feeding machine 101.

[0025] Among them, the movable block 103 is slidably connected to the fixed block 102. The movable block 103 has two fitting grooves 118 and two through holes 119. The fixed block 102 has a number of positioning grooves 120. Two of the sealing members 110 are respectively placed in the corresponding fitting grooves 118. The frame 104 is fixedly connected to the movable block 103. The mounting plate 105 is arranged on the frame 104. The motor 106 is mounted on the mounting plate 105. The output end of the motor 106 is fixedly connected to the elliptical plate 107. Both of the sliding plates 108 are slidably connected to the frame 104. One end of the connecting member is fixedly connected to the corresponding sliding plate 108. The connecting member is slidably connected to the frame 104.

The other end of the plug rod 109 passes through the corresponding through hole 119 and is inserted into the corresponding positioning groove 120. Both ends of the spring 111 are respectively fixedly connected to the corresponding sliding plates 108. Both of the sliding plates 108 are in contact with the elliptical plate 107. By providing the positioning mechanism, during specific use, when it is necessary to adjust the height of the movable block 103, first start the motor 106. The motor 106 drives the elliptical plate 107 to rotate. The elliptical plate 107 abuts against both of the sliding plates 108. Both of the sliding plates 108 drive the spring 111 to elongate and drive the two connecting members to move relative to each other. While the two connecting members move relative to each other, they drive the two plug rods 109 to slide out of the corresponding positioning grooves 120 respectively. Subsequently, the height of the movable block 103 can be adjusted by moving the movable block 103 up and down. After reaching the required height, the motor 106 reverses. The motor 106 drives the elliptical plate 107 to reverse. At this time, the elliptical plate 107 no longer abuts against both of the sliding plates 108. At this time, the spring 111 resets and contracts. The spring 111 drives the two sliding plates 108 to move towards each other. The two sliding plates 108 drive the two connecting members to move towards each other. The two connecting members drive the two plug rods 109 to be respectively inserted into the corresponding positioning grooves 120 for locking and limiting, completing the height adjustment of the movable block 103. The sealing member 110 is used to improve the sealing effect between the movable block 103 and the fixed block 102. In this way, it can solve the technical problem in the prior art that it is necessary for the staff to manually press the pressure rod to move downward to drive the positioning block to move out of the inside of the positioning groove 120, and continuously press the pressure rod to adjust the height of the movable block 103, resulting in a relatively high labor intensity for the staff.

When specifically in use, when the slide plate 108 moves, it drives the connecting rod 115 to move, and the connecting rod 115 drives the connecting block 116 to move, thereby driving the corresponding plug rod 109 to move.

[0027] Meanwhile, the hollow rod 112 is fixedly connected to the housing 104, the rod body 113 is fixedly connected to the mounting plate 105, the rod body 113 is slidably connected to the hollow rod 112, one end of the bolt 114 is inserted into the hollow rod 112 and tightened on the rod body 113. When specifically in use, when installing the motor 106, align the rod body 113 with the hollow rod 112 and push it to the designated position, insert one end of the bolt 114 into the hollow rod 112 and tighten it on the rod body 113, then the installation can be completed. Conversely, it is convenient for disassembly.

[0028] When using the vacuum feeding device of the ultrafine pulverizer according to this embodiment, by setting the positioning mechanism, when specifically in use, when it is necessary to adjust the height of the movable block 103, first start the motor 106, the motor 106 drives the elliptical plate 107 to rotate, the elliptical plate 107 abuts against the two slide plates 108, the two slide plates 108 drive the spring 111 to elongate, and drive the two connectors to move relative to each other. While the two connectors move relative to each other, they drive the two plug rods 109 to slide out of the corresponding positioning grooves 120 respectively. Subsequently, moving the movable block 103 up and down can adjust the height of the movable block 103. After reaching the required height, the motor 106 rotates in reverse, the motor 106 drives the elliptical plate 107 to rotate in reverse. At this time, the elliptical plate 107 no longer abuts against the two slide plates 108. At this time, the spring 111 resets and contracts, the spring 111 drives the two slide plates 108 to move towards each other, the two slide plates 108 drive the two connectors to move towards each other, and the two connectors drive the two plug rods 109 to be inserted into the corresponding positioning grooves 120 respectively for locking and limiting, completing the height adjustment of the movable block 103. The seal 110 is used to improve the sealing effect between the movable block 103 and the fixed block 102. In this way, it can solve the technical problem in the prior art that it is necessary for the staff to manually press the pressure rod to move downward to drive the positioning block to move out of the inside of the positioning groove 120, and continuously press the pressure rod to adjust the height of the movable block 103, resulting in a relatively high labor intensity for the staff.
