The contact area between the stabilizing plate and the ground is small and the stabilizing effect cannot be achieved. When the device is working, the vibration generated will drive the device to move, and the stability of the device is poor. Utility Model Content

[0005] The main purpose of the utility model is to provide a vacuum feeder for material processing, which solves the problem that when the device is working, the vibration generated by the device will drive the device to move, resulting in poor stability of the device, by setting a shock absorbing unit.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A vacuum loader for material processing, comprising a base, a vacuum loader arranged on the top of the base, a movable fixing unit fixedly connected to the bottom of the base, and a shock absorbing unit arranged between the base and the vacuum loader;

[0008] The mobile fixed unit includes a foot brake universal wheel and a hydraulic cylinder fixedly connected to the bottom of the base, and a stabilizing plate fixedly connected to the output end of the hydraulic cylinder for increasing the friction between the device and the ground;

[0009] The shock absorbing unit includes a limiting groove opened in the bottom plate of the base, a spring shock absorber fixedly connected to the bottom wall of the limiting groove, and a bearing seat fixedly connected to the top of the spring shock absorber for supporting the vacuum loader.

[0010] Preferably, the central axis of the hydraulic cylinder coincides with the central axis of the base, and there are four foot brake universal wheels, which are distributed in a rectangular array with the central axis of the hydraulic cylinder as the midpoint.

[0011] Preferably, the movable fixing unit further comprises a pressure sensor embedded in the bottom of the stabilizing plate, and a through hole opened at the top of the stabilizing plate.

[0012] Preferably, the shock absorbing unit also includes a rectangular groove opened on the inner bottom wall of the base, a sliding rod fixedly connected to the inner side wall opposite to the rectangular groove, a movable block movably arranged on the outer side wall of the sliding rod, and a first buffer spring and a second buffer spring which are sleeved on the outer side wall of the sliding rod and respectively located on both sides of the movable block.

[0013] Preferably, one end of the first buffer spring is fixedly connected to the outer side wall of the movable block, and the other end of the first buffer spring is fixedly connected to the inner side wall of the rectangular groove.

[0014] Preferably, one end of the second buffer spring is fixedly connected to the outer side wall of the movable block, and the other end of the second buffer spring is fixedly connected to the inner side wall of the rectangular groove.

[0015] Preferably, the shock absorbing unit also includes a first connecting seat fixedly connected to the top of the movable block, a second connecting seat fixedly connected to the outer wall of the supporting seat, and a connecting rod with one end movably connected to the first connecting seat, and the other end of the connecting rod is movably connected to the second connecting seat.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. In the utility model, the foot brake universal wheel is arranged to facilitate the movement of the device. When it moves to the specified position, the brake pad is stepped on to lock the foot brake universal wheel to preliminarily position the device, and then the hydraulic cylinder is started to drive the stabilizing plate to move downward until the pressure sensor detects that the pressure reaches the set value, that is, the pressure at this time is the overall weight of the vacuum loader plus the base and the shock absorbing unit, so that the foot brake universal wheel is suspended in the air. Because the weight of the vacuum loader is large and the stabilizing plate is against the ground, the contact area between the device and the ground is increased, and the friction is increased to prevent the device from moving during operation.

[0018] 2. In the utility model, when the vacuum loader vibrates, its bearing seat can only move vertically up and down inside the base to prevent the device from generating horizontal force and causing the device to translate. During the movement of the bearing seat, the spring shock absorber provided therein will perform shock absorption and buffering on the bearing seat and the vacuum loader. During the movement of the bearing seat, the second connecting seat, the connecting rod and the first connecting seat will drive the movable block to slide on the sliding rod. Because its movable block is made of rubber, the movable block will be deformed during the sliding process to absorb the vibration force. During the movement of the movable block, the first buffer spring and the second buffer spring will be driven to deform to further absorb the vibration force, thereby further improving the buffering and shock absorption of the device.

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] Embodiment 1: Figure 1-4As shown, a vacuum loader for material processing includes a base 1, a vacuum loader 2 arranged on the top of the base 1, a movable fixing unit 3 fixedly connected to the bottom of the base 1, and a shock absorbing unit 4 arranged between the base 1 and the vacuum loader 2;

[0030] The mobile fixing unit 3 includes a foot brake universal wheel 301 and a hydraulic cylinder 302 fixedly connected to the bottom of the base 1, and a stabilizing plate 303 fixedly connected to the output end of the hydraulic cylinder 302 for increasing the friction between the device and the ground;

[0031] The shock absorbing unit 4 includes a limiting groove 401 opened on the inner bottom plate of the base 1, a spring shock absorber 402 fixedly connected to the inner bottom wall of the limiting groove 401, and a supporting seat 403 fixedly connected to the top of the spring shock absorber 402 for supporting the vacuum loader 2, wherein the bottom end of the supporting seat 403 is inserted into the interior of the limiting groove 401, and the cross-section of the supporting seat 403 matches the cross-section of the limiting groove 401, wherein the longitudinal section of the supporting seat 403 is "T"-shaped, and the longitudinal section of the supporting seat 403 matches the longitudinal section of the base 1.

[0032] The central axis of the hydraulic cylinder 302 coincides with the central axis of the base 1 . There are four foot brake universal wheels 301 , which are arranged in a rectangular array with the central axis of the hydraulic cylinder 302 as the midpoint.

[0033] The mobile fixing unit 3 also includes a pressure sensor 304 embedded in the bottom of the stabilizing plate 303 and a through hole 305 opened on the top of the stabilizing plate 303, wherein the pressure sensor 304 is used to close the hydraulic cylinder 302, and the number and position relationship of the through holes 305 match the foot brake universal wheel 301.

[0034] The foot brake universal wheel 301 is provided to facilitate the movement of the device. When it moves to the specified position, the brake pad is stepped on to lock the foot brake universal wheel 301 to preliminarily position the device, and then the hydraulic cylinder 302 is started to drive the stabilizing plate 303 to move downward until the pressure sensor 304 detects that the pressure reaches the set value, that is, the pressure at this time is the overall weight of the vacuum loader 2 plus the base 1 and the shock absorbing unit 4, so that the foot brake universal wheel 301 is suspended in the air. Because the weight of the vacuum loader 2 is large and the stabilizing plate 303 is against the ground, the contact area between the device and the ground is increased, and the friction is increased to prevent the device from moving during operation. When the fixation is completed, the material is transported to the forming mold (not shown in the figure) through the vacuum loader 2 to realize the processing of the material.

[0035] Embodiment 2: Figure 1-4As shown, a vacuum loader for material processing includes a base 1, a vacuum loader 2 arranged on the top of the base 1, a movable fixing unit 3 fixedly connected to the bottom of the base 1, and a shock absorbing unit 4 arranged between the base 1 and the vacuum loader 2;

[0036] The mobile fixing unit 3 includes a foot brake universal wheel 301 and a hydraulic cylinder 302 fixedly connected to the bottom of the base 1, and a stabilizing plate 303 fixedly connected to the output end of the hydraulic cylinder 302 for increasing the friction between the device and the ground;

[0037] The shock absorbing unit 4 includes a limiting groove 401 opened on the inner bottom plate of the base 1, a spring shock absorber 402 fixedly connected to the inner bottom wall of the limiting groove 401, and a supporting seat 403 fixedly connected to the top of the spring shock absorber 402 for supporting the vacuum loader 2, wherein the bottom end of the supporting seat 403 is inserted into the interior of the limiting groove 401, and the cross-section of the supporting seat 403 matches the cross-section of the limiting groove 401, wherein the longitudinal section of the supporting seat 403 is "T"-shaped, and the longitudinal section of the supporting seat 403 matches the longitudinal section of the base 1.

[0038] The shock absorbing unit 4 also includes a rectangular groove 404 opened on the inner bottom wall of the base 1, a sliding rod 405 fixedly connected to the inner wall opposite to the rectangular groove 404, a movable block 406 movably arranged on the outer wall of the sliding rod 405, and a first buffer spring 407 and a second buffer spring 408 sleeved on the outer wall of the sliding rod 405 and respectively located on both sides of the movable block 406.

[0039] One end of the first buffer spring 407 is fixedly connected to the outer side wall of the movable block 406 , and the other end of the first buffer spring 407 is fixedly connected to the inner side wall of the rectangular groove 404 .

[0040] One end of the second buffer spring 408 is fixedly connected to the outer wall of the movable block 406, and the other end of the second buffer spring 408 is fixedly connected to the inner wall of the rectangular groove 404, wherein the movable block 406 is made of rubber. When the movable block 406 slides on the sliding rod 405, it will drive the first buffer spring 407 and the second buffer spring 408 to deform.

[0041] The shock absorbing unit 4 also includes a first connecting seat 409 fixedly connected to the top of the movable block 406, a second connecting seat 4010 fixedly connected to the outer wall of the supporting seat 403, and a connecting rod 4011 one end of which is movably connected to the first connecting seat 409, and the other end of the connecting rod 4011 is movably connected to the second connecting seat 4010.

[0042] When the vacuum feeder 2 is working, the bottom end of the bearing seat 403 is inserted into the interior of the limiting groove 401, and the cross section of the bearing seat 403 matches the cross section of the limiting groove 401, wherein the longitudinal section of the bearing seat 403 is in a "T" shape, and the longitudinal section of the bearing seat 403 matches the longitudinal section of the base 1. Therefore, when the vacuum feeder 2 vibrates, the bearing seat 403 can only move vertically up and down inside the base 1 to prevent the device from generating a horizontal force, which causes the device to move horizontally. In addition, during the movement of the bearing seat 403, the spring shock absorber 402 provided therein will exert pressure on the bearing seat 403. 03 and the vacuum loader 2 perform shock absorption and buffering, and the supporting seat 403 is in the process of moving, and through the second connecting seat 4010, the connecting rod 4011 and the first connecting seat 409, the movable block 406 is driven to slide on the sliding rod 405. Because the movable block 406 is made of rubber material, the movable block 406 will be deformed during the sliding process to absorb the vibration force, and the movable block 406 will drive the first buffer spring 407 and the second buffer spring 408 to deform during the movement, thereby further absorbing the vibration force, so as to further improve the buffering and shock absorption of the device.
