Description

Technical Field

[0001] This utility model relates to the field of vacuum feeding machine technology, and in particular to an automatic material suction trolley. Background Technology

[0002] A vacuum feeder is an automated device that utilizes the principle of vacuum negative pressure to achieve the closed-loop conveying of powder and granular materials. It is widely used in industries such as pharmaceuticals, food, and chemicals. In practical applications, it often works in conjunction with a dedicated feeding trolley: the material is pre-poured into the hopper of the mobile trolley, and the feeder, through a suction tube inserted into the trolley, draws the material through the conveying pipe to the target equipment under the action of a vacuum generator. This combination of "feeder + trolley" greatly facilitates short-distance material transfer and feeding, effectively reduces dust dispersion, and improves the cleanliness and automation level of the production process. Working together, they form a crucial link in the material flow within the workshop.

[0003] However, this traditional model has a significant drawback: during the suction process, to prevent material from accumulating in the corners of the trolley and forming "dead zones," operators must constantly move and adjust the position of the heavy suction tube inside the trolley throughout the entire process. This not only results in high operational intensity and low efficiency but also poses certain safety and hygiene risks due to prolonged close contact between personnel and the work area. This manual intervention has become a major bottleneck restricting the realization of full automation and improved ease of use of this combined system.

[0004] Therefore, further improvements are needed. To this end, we propose an automatic material suction trolley. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an automatic material suction trolley.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic material suction trolley, including a base plate, a trolley body fixed to the middle of the upper surface of the base plate, the top of the trolley body being an open design, and a horizontal plate being horizontally arranged at the top of the trolley body, a through hole being opened on the side of the horizontal plate near the center of the trolley body, a suction pipe being slidably connected inside the through hole, and a flexible hose being connected between the top of the suction pipe and a vacuum generator, a baffle being fixed to the top surface of the suction pipe, and a tension spring being fixedly connected to the lower surface of the baffle and the upper surface of the horizontal plate, a reduction motor being provided on the upper surface of the horizontal plate to drive the baffle to move up and down, and a transverse moving component being fixed to the side of the top of the trolley body to drive the horizontal plate to move back and forth.

[0007] Furthermore, multiple casters are fixed to the lower surface of the base plate, and handles are fixed to the outer side wall of the vehicle body.

[0008] Furthermore, the vehicle body has sloping bottoms on both sides at the bottom end, and the sloping bottoms are inclined towards the bottom of the suction pipe. The lower surface of the sloping bottoms of the vehicle body and the upper surface of the base plate are both fixed with support rods.

[0009] Furthermore, a housing is fixed to the upper surface of the horizontal plate, the geared motor is located inside the housing, the output shaft of the geared motor passes through the housing and is fixedly connected to an eccentric cam, and the side of the eccentric cam is in contact with the lower surface of the baffle.

[0010] Furthermore, the lateral movement assembly includes a side shell fixed to the outer wall of the vehicle body, and the side shell communicates with the interior of the vehicle body. A reciprocating lead screw is rotatably connected to the inside of the side shell via a bearing. An internal threaded slider is rotatably connected to the surface of the reciprocating lead screw via a thread. The internal threaded slider is slidably connected to the inner wall of the side shell. A servo motor is fixed to one end of the outer wall of the side shell. One end of the reciprocating lead screw is fixedly connected to the output end of the servo motor. The horizontal plate is fixedly connected to the surface of the internal threaded slider.

[0011] Furthermore, a guide rod is fixed inside the side shell, the guide rod passes through the internal threaded slider, and is slidably connected to the internal threaded slider.

[0012] The beneficial effects of this utility model are:

[0013] 1. In use, this utility model is equipped with a vehicle body, a cross plate, a suction pipe, a flexible hose, a transverse moving assembly, and casters. The flexible hose is connected to a vacuum generator, thereby sucking out the material inside the vehicle body through the flexible hose and the suction pipe. During this process, the transverse moving assembly drives the cross plate and the suction pipe to move back and forth inside the vehicle body, eliminating the need for manual handling of the suction pipe inside the vehicle body, thus achieving automatic material suction and improving the convenience of using the vehicle.

[0014] 2. When in use, this utility model is equipped with a horizontal plate, a suction pipe, a baffle, a tension spring, a reduction motor, and an eccentric cam. During the reciprocating movement of the horizontal plate and the suction pipe inside the vehicle body, the reduction motor drives the eccentric cam to rotate. The eccentric cam pushes the baffle upward, and the tension spring pulls the baffle downward, thereby realizing the reciprocating movement of the baffle and the suction pipe, preventing material from accumulating and being compacted at the bottom of the suction pipe and thus preventing it from being sucked out.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, an automatic material suction trolley is disclosed, comprising a base plate 1, a trolley body 2 fixed to the middle of the upper surface of the base plate 1, the top of the trolley body 2 being an open design, and a horizontal plate 3 being horizontally arranged at the top of the trolley body 2. A through hole 31 is provided on the side of the horizontal plate 3 near the center of the trolley body 2, and a suction pipe 4 is slidably connected inside the through hole 31. A flexible hose 5 is connected between the top of the suction pipe 4 and a vacuum generator. A baffle 41 is fixed to the top surface of the suction pipe 4, and a tension spring 42 is fixedly connected to the lower surface of the baffle 41 and the upper surface of the horizontal plate 3. A reduction motor 7 is provided on the upper surface of the horizontal plate 3 to drive the baffle 41 to move up and down. A transverse moving assembly 8 is fixed to the side of the top of the trolley body 2 to drive the horizontal plate 3 to move back and forth.

[0024] In this embodiment, the vacuum generator is a mechanism of the vacuum feeder, which is connected to the vacuum pump. The specific structure and working principle will not be described in detail here. Through the vacuum pump, the material inside the vehicle body 2 can be sucked into the vacuum generator through the hose 5 and the suction pipe 4.

[0025] Multiple casters 9 are fixed to the lower surface of the base plate 1, and handles 10 are fixed to the outer side wall of the vehicle body 2.

[0026] In this embodiment, the universal wheel 9 is a universal wheel with a locking structure. The vehicle body 2 can be moved by the universal wheel 9, and the vehicle can be pushed to move by the handle 10.

[0027] The bottom of the vehicle body 2 is provided with sloping bottoms 21 on both sides, and the sloping bottoms 21 are inclined toward the bottom of the suction pipe 4. The lower surface of the sloping bottoms 21 of the vehicle body 2 and the upper surface of the base plate 1 are fixed with support rods.

[0028] When the interior of the vehicle body 2 is filled with powdered material, as the material is drawn away by the suction pipe 4, the material will flow along the inclined bottom 21 toward the middle of the vehicle body 2, making it convenient for the suction pipe 4 to draw in the material. The suction pipe 4 only needs to move horizontally along the middle of the inclined bottom 21 on both sides.

[0029] A housing 6 is fixed on the upper surface of the horizontal plate 3. The geared motor 7 is located inside the housing 6. The output shaft of the geared motor 7 passes through the housing 6 and is fixedly connected to an eccentric cam 71. The side of the eccentric cam 71 is in contact with the lower surface of the baffle 41.

[0030] After the reduction motor 7 is started, the eccentric cam 71 is driven to rotate slowly. When the longer end of the eccentric cam 71 rotates to the top, it will push the baffle 41 upward. As the longer end of the eccentric cam 71 rotates downward, the tension spring 42 will pull the baffle 41 downward. During this process, the baffle 41 remains in contact with the side of the eccentric cam 71. As the eccentric cam 71 continues to rotate, with the cooperation of the tension spring 42, the baffle 41 and the suction pipe 4 move up and down reciprocally. This prevents the material inside the vehicle body 2 and located below the suction pipe 4 from being compacted and unable to be sucked out.

[0031] The lateral movement assembly 8 includes a side shell 81 fixed to the outer wall of the vehicle body 2, and the side shell 81 is connected to the interior of the vehicle body 2. A reciprocating screw 83 is rotatably connected to the inside of the side shell 81 through a bearing. An internal thread slider 82 is rotatably connected to the surface of the reciprocating screw 83 through a thread. The internal thread slider 82 is slidably connected to the inner wall of the side shell 81. A servo motor 85 is fixed to one end of the outer wall of the side shell 81. One end of the reciprocating screw 83 is fixedly connected to the output end of the servo motor 85. The horizontal plate 3 is fixedly connected to the surface of the internal thread slider 82.

[0032] When the material inside the vehicle body 2 is sucked out through the suction pipe 4, the servo motor 85 is started to drive the reciprocating screw 83 to rotate. The reciprocating screw 83 will drive the internal thread slider 82 to move back and forth along the inner wall of the side shell 81, thereby driving the horizontal plate 3 and the suction pipe 4 to move back and forth inside the vehicle body 2, without the need for manual hand-held suction pipe 4 to suck out material.

[0033] A guide rod 84 is fixed inside the side shell 81. The guide rod 84 passes through the internal thread slider 82 and is slidably connected to the internal thread slider 82.

[0034] By setting the guide rod 84, the torque on the reciprocating lead screw 83 can be borne, thus guiding and protecting the reciprocating lead screw 83.

[0035] Working principle: Move the trolley to one side of the vacuum feeder, connect the hose 5 to the inlet of the vacuum generator, and then pour the material into the trolley body 2.

[0036] During loading, the vacuum generator and its connected vacuum pump are activated to create negative pressure in the hose 5 and suction pipe 4, initiating material suction. Simultaneously, the servo motor 85 is activated, driving the reciprocating screw 83 to rotate. This causes the threaded slider 82, connected to the screw, to slide back and forth along the guide rod 84, allowing the horizontal plate 3 and suction pipe 4, fixed to the threaded slider 82, to move automatically laterally back and forth within the vehicle body 2. At the same time, the reduction motor 7 is activated, driving the eccentric cam 71 to rotate slowly and continuously. When the long end of the cam rises, it pushes the baffle 41 and suction pipe 4 upwards; when the cam turns to the short end, the baffle 41 and suction pipe 4 fall downwards under the reset action of the tension spring 42. This cycle repeats, creating a reciprocating shaking motion of the suction pipe 4. The sloping bottom structure 21 at the bottom of the vehicle body 2 allows the material to flow naturally towards the center. Combined with the lateral movement and shaking of the suction pipe 4, this effectively prevents material accumulation or compaction, achieving fully automatic, dead-angle-free, and highly efficient material suction operation.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
