Description

Technical Field

[0001] This utility model relates to the field of skin care product packaging technology, specifically a vacuum-sealed feeding device. Background Technology

[0002] In the packaging of skincare products, vacuum sealing is often used. This requires manual feeding, arranging the bagged materials in order, and finally vacuum sealing at a vacuum sealing machine. Manual feeding is labor-intensive and inefficient.

[0003] In the prior art, Chinese patent CN209988179U discloses a vacuum packaging machine that facilitates material feeding. It includes a machine body, a conveyor belt rotatably connected to the machine body, a power device for driving the conveyor belt to rotate, a placement strip on the conveyor belt for placing packaging bags to be packaged, and a packaging device on the machine body for vacuum sealing the packaging bags.

[0028] 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.

[0029] Example 1

[0030] Please see Figure 1-6 A vacuum-sealed feeding device includes a frame 1, a placement rack 2, a conveying unit 3, and a feeding unit 4. The conveying unit 3 is connected to the frame 1 and arranged along the length of the frame 1. The placement rack 2 is connected to the frame 1 and located above the conveying unit 3. The feeding unit 4 is connected to the frame 1 and can move along the length of the frame 1. The feeding unit 4 is used to absorb the material located on the placement rack 2 and place it on the conveying unit 3. The placement rack 2 is provided with a plurality of baffle assemblies 21. A receiving portion 22 for storing material is formed between two adjacent baffle assemblies 21. The baffle assembly 21 is provided with a locking member 211. The baffle assembly 21 can move along the width direction of the placement rack 2 to adjust the width of the receiving portion 22 and is locked to the placement rack 2 by the locking member 211.

[0031] In practical applications, staff place materials into the receiving section 22. It should be noted that, in this embodiment, the material mentioned is an eye mask packaged in a bag. The material is placed in the receiving section 22, and the baffle assembly 21 limits the material. Then, the feeding unit 4 can adsorb the material in the receiving section 22. After adsorption, it is placed on the conveying unit 3 and conveyed to the external vacuum sealing machine for vacuum sealing. When vacuum sealing materials of different sizes is required, the staff only needs to loosen the locking piece 211 and then adjust the position of the baffle assembly 21 to widen the gap between adjacent baffle assemblies 21, that is, to widen the width of the receiving section 22. Then, the locking piece 211 locks the baffle assembly 21 onto the placement frame 2, thus completing the operation of adjusting the width of the receiving section 22. The adjustable baffle assembly 21 allows the staff to easily adjust the width of the receiving section 22, thus making it suitable for materials of different sizes.

[0032] Preferably, the baffle assembly 21 includes a limiting plate 212 and a plate body 213 with a T-shaped horizontal cross section. The vertical part of the plate body 213 is inserted into the limiting plate 212. The limiting plate 212 is locked to the side of the placement frame 2 away from the feeding unit 4 by a locking member 211. The horizontal part of the plate body 213 is located on the other side of the placement frame 2. A slide rail 23 is provided on the side of the placement frame 2 near the horizontal part of the plate body 213. The horizontal part of the plate body 213 is locked in the slide rail 23 by the locking member 211.

[0033] In this embodiment, there are three locking members 211. Two locking members 211 are used to lock the limiting plate 212, and are located at the top of the side of the limiting plate 212 closest to the plate body 213 and the bottom of the other side, respectively. Both are locked on the placement frame 2. One locking member 211 is used to lock the plate body 213, locking the bottom of the plate body 213 away from the limiting plate 212 in the slide rail 23, that is, on the placement frame 2. In this way, the limiting plate 212 and the plate body 213 can be better fixed, improving the stability of the limiting plate 212 and the plate body 213. When adjusting, you only need to loosen the locking member 211 and then drag the limiting plate 212 and the plate body 213 to make the adjustment, thus adapting to materials of different sizes.

[0034] Preferably, the placement rack 2 is provided with a baffle 24, which contacts the horizontal part of the plate 213. The baffle 24 is arranged along the width direction of the placement rack 2. A plurality of blocking blocks 231 are provided on the slide rail 23. The blocking blocks 231 are fixed in the slide rail 23 by bolts. The blocking blocks 231 are arranged one-to-one with the receiving part 22. The blocking blocks 231 are used to block the bottom of the material, and the baffle 24 is used to block the top of the material. The blocking blocks 231 and the baffle 24 are used to prevent the material from falling from the receiving part 22.

[0035] With the above design, when the material is placed in the receiving section 22, its two sides are blocked by the T-shaped plates 213, thus preventing the material from falling out of the receiving section 22. The baffle 24 and the blocking block 231 further prevent the material from falling out of the receiving section 22. Specifically, although the two sides of the material are blocked by the plates 213, if the material tilts left or right during placement or subsequent loading, one of the plates 213 will fail to provide adequate protection, and the material will fall out of the receiving section 22. However, the baffle 24 blocking the upper part of the material and the blocking block 231 blocking the bottom of the material prevent the material from falling out of the receiving section 22 when it tilts left or right. Furthermore, since the material will contact the bottom of the receiving section 22 under the influence of gravity when placed in it, the top of the blocking block 231 protrudes in this embodiment. The design ensures that the top of the shielding part is higher than the bottom of the receiving part 22, thus guaranteeing that the shielding block 231 can block the bottom of materials of different sizes. The baffle 24 can be adjusted in height relative to the placement rack 2. Specifically, in this embodiment, the baffle 24 is adjustable as follows: the placement rack 2 is provided with a sliding groove, and the sliding groove is provided with an adjustable slider. The slider is locked in the sliding groove by bolts, and the baffle 24 is fixedly connected to the top of the slider. The baffle 24 can move in the height direction of the placement rack 2 by the slider. In this way, the operator can adjust the height position of the baffle 24 according to the size of the material, which makes it more convenient to use. On the other hand, since the material is not rigid and has a certain deformation, when the feeding unit 4 absorbs the material, the upper, lower and sides of the material can undergo a certain deformation, and then be absorbed by the feeding unit 4 from the receiving part 22 for subsequent feeding.

[0036] Preferably, the placement rack 2 is provided with multiple support plates 25, the support plates 25 are located between two adjacent plates 213, the two adjacent plates 213 and the support plates 25 form a receiving part 22, the frame 1 is inclined, the conveying unit 3 connected to the frame 1 and the placement rack 2 are both inclined, the end of the placement rack 2 near the feeding unit 4 is inclined downward, and the support plates 25 can move along the inclined direction of the placement rack 2.

[0037] In this embodiment, the entire feeding device is arranged at an angle, and the end of the placement rack 2 near the unloading unit is designed to tilt downwards. The support plate 25 is movable. During continuous feeding, the material is absorbed by the feeding unit 4 within the receiving portion 22 formed by the two adjacent plates 213 and the support plate 25. Therefore, as the material in the receiving portion 22 decreases, a gap will exist between the support plate 25 and the material. When the feeding unit 4 absorbs the material, the material will move towards the gap when it comes into contact with the material, reducing the absorption effect. Meanwhile, the support plate 25 will move downwards towards the placement rack 2 under the influence of gravity. In other words, the support plate 25 fills the gap between the support plate 25 and the material, so that when the feeding unit 4 comes into contact with the material, the material will not be excessively displaced, thereby improving the adsorption effect of the adsorbed material. As a preferred embodiment of this embodiment, a counterweight can be set on the side of the support plate 25 away from the feeding unit 4. The counterweight can ensure that the support plate 25 can be adjusted as the material decreases. Specifically, when the material in the accommodating part 22 decreases, the counterweight will press the support plate 25 to move along the inclined direction of the placement frame 2. When the feeding unit 4 adsorbs the material, the support plate 25 can prevent the material from being excessively displaced, thereby improving the adsorption effect of the material.

[0038] Preferably, the feeding unit 4 includes a gantry frame 41, a lifting drive unit 42, a motor 43, a bracket 44, and multiple suction cup assemblies 45. The frame 1 has a horizontal drive unit 12 and a first sliding unit 11 on both sides along its length. The two columns of the gantry frame 41 are connected to the horizontal drive unit 12 and the first sliding unit 11, respectively. The lifting drive unit 42 is connected to the side of the gantry frame 41 near the placement rack 2. The side of the gantry frame 41 near the placement rack 2 also has a second sliding unit 412. The lifting drive unit 42 and the second sliding unit 412 are respectively mounted on the two columns and extend along the length of the columns. The two ends of the bracket 44 are respectively connected to the lifting drive unit 42 and the second sliding unit 412. The bracket 44 has a rotatable connecting shaft 441. The motor 43 is bolted to one side of the bracket 44. The output end of the motor 43 passes through the bracket 44 and is fixedly connected to the connecting shaft 441. Multiple suction cup assemblies 45 are connected to the connecting shaft 441 in an adjustable manner.

[0039] Through the above design, the gantry frame 41 is driven by the horizontal drive unit 12 and can move along the length of the frame 1. Specifically, one column of the gantry frame 41 is driven by the horizontal drive unit 12, and the other column is slidably connected to the first sliding unit 11. Therefore, when the gantry frame 41 is driven by the horizontal drive unit 12, one column of the gantry frame 41 moves, and the other column slides along the first sliding unit 11. The entire gantry frame 41 can move along the length of the frame 1. The lifting drive unit 42, motor 43, bracket 44, and multiple suction cup assemblies 45 are all driven by the gantry frame 41. On the other hand, one end of the bracket 44 is driven by the lifting drive unit 42 and can be lifted and lowered along the height of the gantry frame 41. The other end of the bracket 44 is slidably connected to the second sliding unit 412, so the bracket 44 can be raised and lowered along the height direction of the gantry 41 via the lifting drive unit 42, and the motor 43 can move synchronously with the bracket 44, so the motor 43 will also rise and fall with the bracket 44. Multiple suction cup assemblies 45 are connected to the connecting shaft 441, and the connecting shaft 441 is driven to rotate by the motor 43, so that the suction cup assembly 45 can pick up the material in the receiving part 22, and then place it on the conveying unit 3 for conveying by rotating it. Through the horizontal drive unit 12, the lifting drive unit 42, and the motor 43, the material can be picked up from the receiving part 22 and placed on the conveying unit 3, thereby realizing the feeding action and picking up the material more smoothly.

[0040] Preferably, the suction cup assembly 45 includes a fixing block 451, a ventilation pipe 452, a suction cup 453, and a T-nut 454. The connecting shaft 441 is provided with a T-groove 442, the length of which extends along the length direction of the connecting shaft 441. The T-nut 454 matches the T-groove 442 and can slide within the T-groove 442. The fixing block 451 has a threaded hole and is fixed to the connecting shaft 441 by bolts, threaded holes, and T-nut 454. The ventilation pipe 452 passes through the fixing block 451, one end of which is connected to the suction cup 453, and the other end is connected to an external air pump.

[0041] In the above design, the fixing block 451 can be fixed in the T-slot 442 by the T-nut 454. When the air pump is working, the air pipe 452 will guide the air from the air pump to the suction cup 453, so that the suction cup 453 can pick up the material. Specifically, the air pipe 452 passes through the fixing block 451. The section connected to the air pump is made of flexible material, and the section connected to the suction cup 453 is made of rigid material. This allows the suction cup 453 to better pick up the material. On the other hand, when the operator needs to adjust the position of the suction cup 453, he only needs to loosen the T-nut 454 and then drag the fixing block 451 to adjust the position of the suction cup 453. Finally, he only needs to tighten the T-nut 454 at the adjusted position. It should be noted that the pipeline routing of the air pipe 452 and the air pump is not shown in the figure in this embodiment.

[0042] Preferably, the lifting drive unit 42 is a first motor 43 lead screw module, the horizontal drive unit 12 is a second motor 43 lead screw module, the first sliding unit 11 is a first guide rod slider module, the second sliding unit 412 is a second guide rod slider module, one column of the gantry frame 41 is fixedly connected to the slider of the first guide rod slider module, and the other column is connected to the moving block of the first motor 43 lead screw module; one end of the bracket 44 is connected to the moving block of the second motor 43 lead screw module, and the other end is fixedly connected to the second guide rod slider module.

[0043] In this embodiment, both the horizontal drive unit 12 and the lifting drive unit 42 are motor 43 lead screw modules. The motor 43 that drives the motor 43 lead screw is a stepper motor 43. This can not only drive the gantry 41 and the support 44 to move smoothly, but also drive the gantry 41 and the support 44 to move to the designated position with precision, ensuring the smooth operation of the loading. On the other hand, in this embodiment, both the first sliding unit 11 and the second sliding unit 412 are guide rod modules, which can make the gantry 41 and the support 44 slide more smoothly on the guide rod module.

[0044] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
