Description

Technical Field

[0001] This utility model relates to the field of vacuum feeding technology, specifically a lifting mechanism for a vacuum feeding machine. Background Technology

[0002] Vacuum feeders, as a new type of pollution-free feeding device, have been quickly recognized by the market and widely promoted due to their low pollution and low cost. Since vacuum feeders use vacuum suction to continue feeding, their main body is mostly made of tanks.

[0003] Currently, some vacuum feeders have a Z-shaped support frame structure, and the support column is connected to the machine by a single connecting rod. When the tank is full of material, the weight of the entire main body is extremely high, which puts a great burden on the connecting rod and support column. Long-term high-pressure operation can cause the connecting rod and support column to bend. Utility Model Content

[0004] The purpose of this invention is to provide a lifting mechanism for a vacuum feeder to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lifting mechanism for a vacuum feeder includes:

[0007] A balance support frame, the balance support frame including a base plate;

[0008] The lifting structure is fixedly installed on the front edge of the upper surface of the substrate. The lifting structure includes a base column, a groove is opened inside the base column, a slider is slidably installed in the groove, the slider is fixedly installed at the rear end of the first connecting rod and the second connecting rod, and a reinforcing support column is fixedly connected between the first connecting rod and the second connecting rod.

[0009] The feeding structure is slidably installed on the front end of the first connecting rod and the second connecting rod.

[0010] Furthermore, the balance support frame also includes:

[0011] A stabilizing edge strip is fixedly installed at both ends of the front side of the substrate;

[0012] The first reinforcing strut, the lower end of which is fixedly connected to the two sides of the base plate;

[0013] The second reinforcing strut, the lower end of which is fixedly connected to the upper side of the stabilizing edge strip;

[0014] The base beam is fixedly connected to the upper end of the first reinforcing strut on its bottom side, and to the upper end of the second reinforcing strut on one front end of the base beam. The middle part of the base beam is fixedly connected to both sides of the base column.

[0015] Furthermore, the lifting structure also includes:

[0016] A lead screw, which is rotatably mounted in a slide groove and is engaged with a slider.

[0017] The base block is fixedly installed at the lower end of the base column and at the front edge of the upper surface of the substrate.

[0018] Furthermore, the lifting structure also includes:

[0019] A worm gear is rotatably mounted inside the base block and is fixedly sleeved to the lower end of the lead screw;

[0020] A worm gear, which is rotatably mounted inside the base block, and meshes with a worm wheel;

[0021] A drive motor is fixedly mounted on the upper surface of the substrate, and the output end of the drive motor is fixedly connected to the worm gear.

[0022] Furthermore, the feeding structure also includes:

[0023] A vacuum hopper, the rear side of which is fixedly connected to the front end of the first connecting rod;

[0024] A material collection hopper is fixedly installed at the lower opening of a vacuum hopper.

[0025] The discharge port is fixedly installed at the lower opening of the material collection hopper;

[0031] Compared with the prior art, the beneficial effects of this utility model are:

[0032] 1. The feeding structure is supported by a balance support frame and a base column. Two sliders slide up and down synchronously in the chute. The feeding structure moves up and down through a connecting frame composed of connecting rod 1 and connecting rod 2, achieving separation and docking with the feed inlet of the processing equipment. Connecting rod 1 and connecting rod 2 cooperate with each other and are reinforced by a reinforcing support column in the middle of the two connecting rods. The column abuts against the two connecting rods to strengthen the support strength of the overall connecting frame, increase the upper limit of the overall weight of the connected feeding structure, and prevent the single connecting rod from bending due to the excessive weight of the feeding structure during long-term use.

[0033] 2. The support range of the base structure, such as the substrate, is increased by two stabilizing side strips. The multiple triangular support structure composed of the No. 1 and No. 2 reinforcing struts and the base beam provides support on both sides of the base column. Compared with the traditional Z-shaped structure, it has higher stability and effectively avoids bending of the base column due to mechanical fatigue caused by long-term operation.

Detailed Implementation

[0039] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see Figure 1-4 In this embodiment of the present invention, a lifting mechanism for a vacuum feeder includes a balance support frame 1, a lifting structure 2, and a feeding structure 3. The balance support frame 1 includes a base plate 101. The lifting structure 2 is fixedly installed on the front edge of the upper surface of the base plate 101. The lifting structure 2 includes a base column 201. A groove 202 is provided inside the base column 201. A slider 207 is slidably installed in the groove 202. The slider 207 is fixedly installed at the rear end of a first connecting rod 204 and a second connecting rod 205. A reinforcing support column 206 is fixedly connected between the first connecting rod 204 and the second connecting rod 205. The feeding structure 3 is slidably installed at the front end of the first connecting rod 204 and the second connecting rod 205.

[0041] Specifically, the feeding structure 3 is supported by the balance support frame 1 and the base column 201. Two sliders 207 slide up and down synchronously in the slide groove 202. The connecting frame composed of the first connecting rod 204 and the second connecting rod 205 drives the feeding structure 3 to move up and down, realizing the separation and docking with the feed port of the processing equipment. The first connecting rod 204 and the second connecting rod 205 cooperate with each other, and the reinforcing support column 206 reinforces the middle of the two connecting rods and abuts against the two connecting rods to strengthen the support strength of the overall connecting frame, increase the upper limit of the overall weight of the connected feeding structure 3, and avoid the bending of a single connecting rod due to the excessive weight of the feeding structure 3 during long-term use.

[0042] Example 1

[0043] like Figure 3 As shown, in this embodiment, the lifting structure 2 further includes a lead screw 203, a base block 208, a worm gear 209, a worm 210, and a drive motor 211. The lead screw 203 is rotatably installed in the slide groove 202, and the lead screw 203 is screwed into the slider 207. The base block 208 is fixedly installed at the lower end of the base column 201 and is fixedly installed on the front edge of the upper surface of the substrate 101. The worm gear 209 is rotatably installed inside the base block 208 and is fixedly sleeved with the lower end of the lead screw 203. The worm 210 is rotatably installed inside the base block 208, and the worm 210 meshes with the worm gear 209. The drive motor 211 is fixedly installed on the upper surface of the substrate 101, and the output end of the drive motor 211 is fixedly connected to the worm 210.

[0044] In this embodiment, the worm gear 210 is driven to rotate by the drive motor 211, which in turn rotates the lead screw 203 by rubbing the worm wheel 209, and the slider 207 slides up and down in the groove 202, thereby controlling the lifting and lowering of the feeding structure 3.

[0045] like Figure 4 As shown, in this embodiment, the feeding structure 3 further includes a vacuum hopper 301, a collecting hopper 302, a discharge port 303, a suction pipe 304, an extension pipe interface 305, a gas supply pipe 306, and a vacuum chamber 307. The rear side of the vacuum hopper 301 is fixedly connected to the front end of the first connecting rod 204; the collecting hopper 302 is fixedly installed at the lower opening of the vacuum hopper 301; the discharge port 303 is fixedly installed at the lower opening of the collecting hopper 302; one end of the suction pipe 304 is fixedly connected to the collecting hopper 302; the extension pipe interface 305 is fixedly installed on the side surface of the discharge port 303; one end of the gas supply pipe 306 is fixedly connected to the upper side of the vacuum hopper 301; and the vacuum chamber 307 is fixedly installed on the upper surface of the substrate 101, with the upper side of the vacuum chamber 307 fixedly connected to the other end of the gas supply pipe 306.

[0046] In practice, the air in the vacuum hopper 301 is extracted through the air supply pipe 306 via the vacuum box 307 to form a relative vacuum environment. The material is then sucked into the vacuum hopper 301 through the suction pipe 304 for temporary storage. After being guided by the material collection hopper 302 and the discharge port 303, the material is fed into the processing equipment.

[0047] Example 2

[0048] Based on Embodiment 1, in order to compensate for the fact that the lifting of the vacuum hopper 301 in Embodiment 1 relies entirely on the base column 201, when the vacuum hopper 301 is full of material, the weight is extremely large, and the base column 201 will bend due to mechanical fatigue after long-term use.

[0049] like Figure 2 As shown, in this embodiment, the balance support frame 1 further includes a stabilizing edge strip 102, a first reinforcing support rod 103, a second reinforcing support rod 104, and a base beam 105. The stabilizing edge strip 102 is fixedly installed at both ends of the front side of the base plate 101; the lower end of the first reinforcing support rod 103 is fixedly connected to the two side edges of the base plate 101; the lower end of the second reinforcing support rod 104 is fixedly connected to the upper side of the stabilizing edge strip 102; the bottom side of the base beam 105 is fixedly connected to the upper end of the first reinforcing support rod 103, the upper end of the second reinforcing support rod 104 is fixedly connected to one end of the front side of the base beam 105, and the middle part of the base beam 105 is fixedly connected to both sides of the base column 201.

[0050] In practice, the force application range of the base structure such as the substrate 101 is increased by two stabilizing side strips 102, and the support structure composed of the first reinforcing strut 103, the second reinforcing strut 104 and the base beam 105 provides support on both sides of the base column 201. Compared with the traditional Z-shaped structure, it has higher stability and effectively avoids bending of the base column 201 due to mechanical fatigue caused by long-term operation.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
