Description

Technical Field

[0001] This utility model relates to the field of automated packaging technology, and in particular to a powder box opening machine. Background Technology

[0002] In daily life, for cosmetic products such as pressed powder, loose powder, and blush, these products need to be placed into corresponding powder cases. After the powder cases are manufactured, the lids are closed. For snap-on powder cases, one side of the lid rotates to connect to the case body, while the other end is fixed by a snap. Normally, a gap is left between the lid and the case body on the snap-on side to facilitate the user opening the lid later.

[0003] Before loading the product, the clips and lid need to be opened to facilitate subsequent product filling. For clip-on powder cartridges, opening requires first knocking open the clips, then rotating the lid along the rotating end until it opens. During the opening process, the powder cartridge needs to be relatively fixed to facilitate opening. Traditionally, this is done by installing a clamping device on the conveyor line to clamp the cartridge during opening, which necessitates modifying and adjusting the entire conveyor line structure to adapt it. This requires adapting the conveyor mechanism to different products, resulting in a significant engineering workload. Furthermore, in current automated production lines, powder cartridges are often opened manually before being placed on the conveyor mechanism, which greatly reduces the efficiency of automated production. Utility Model Content

[0004] Purpose of the utility model: In view of the problems existing in the prior art, this utility model provides a powder box opening machine. By setting an opening support seat above the transmission line, the powder box to be opened is transferred to the opening support seat through the box feeding component. The opening operation of the powder box is completed by the powder box top and the auxiliary opening component. It does not affect the transmission of the transmission line and can realize the automated opening operation.

[0005] Technical Solution: This utility model provides a powder box opening machine, including a transmission line set on a workbench. A multi-station opening support is fixed above the center of the transmission line via a first bracket. A clamping component slides on the opening support. A powder box top is located on one side of the multi-station support, facing the opening support. A first driving component is connected to the powder box top to drive the powder box top to move forward and backward and up and down. An auxiliary opening component and a second driving component to drive the auxiliary opening component to move left and right, forward and backward, and up and down are also provided on the same side as the powder box top. A box feeding component and a third driving component to drive the box feeding component to move up and down and forward and backward are provided on the other side of the transmission line facing the powder box top.

[0006] Furthermore, a limiting stop bar is fixed at the middle position of the transmission line and is arranged along the direction of the transmission line. The box to be opened is transmitted on the transmission line between the limiting stop bar and the box feeding component. A box-pushing cylinder facing the limiting stop bar and a push plate set at the execution end of the box-pushing cylinder are fixed on the worktable facing the limiting stop bar.

[0007] Furthermore, a pair of support plates are fixed on the workbench located on one side of the box feeding assembly, and a guide positioning rod parallel to the limit stop is fixed between the pair of support plates.

[0008] Furthermore, multiple limiting cylinders are fixed on the workbench located on one side of the box feeding assembly. The end of the limiting cylinder is provided with a first limiting plate perpendicular to the transmission line. A second limiting plate is also fixed on the workbench. The second limiting plate is located to the right of a pair of first limiting plates, and the distance between the pair of first limiting plates and the second limiting plate is equal.

[0009] Furthermore, the box-opening support includes a pair of strip plates and a pair of first partitions fixed at intervals on the strip plates. The clamping assembly includes a sliding plate slidably connected between the pair of strip plates and matching the height of the strip plates. A second partition is fixed at intervals on the sliding plate. One end of the sliding plate is disposed at the actuating end of a clamping cylinder.

[0010] Furthermore, the driving component includes a top extension cylinder and a first longitudinal cylinder. The top extension cylinder is fixed on the second bracket. The first longitudinal cylinder is vertically arranged and its actuating end is fixed to the second bracket. The actuating end of the top extension cylinder is fixedly connected to the top of the powder box.

[0011] Furthermore, the auxiliary box-opening assembly includes at least one auxiliary box-opening rod arranged parallel to the transmission line direction, and a fixing plate for fixing the auxiliary box-opening rod; the second driving component includes a first front and rear cylinder matching the number of auxiliary box-opening rods, at least one second longitudinal cylinder, and a left and right sliding cylinder, the actuating end of the first front and rear cylinder is fixedly connected to the fixing plate, the actuating end of the second longitudinal cylinder is fixed to a third bracket, and the first front and rear cylinders are fixed on the third bracket; the second longitudinal cylinder is slidably arranged on a slide rail, and the actuating end of the left and right sliding cylinder is connected to the second longitudinal cylinder.

[0012] Furthermore, the lower surface of the third support is also provided with a set of feeding suction cups that match the number of box-opening support seats.

[0013] Furthermore, the box feeding assembly includes a feeding suction cup group that matches the number of box opening support seats and is connected by a fourth bracket.

[0014] Furthermore, the driving component three also includes a fourth longitudinal cylinder, the actuating end of which is fixedly connected to the second front and rear cylinders.

[0015] Beneficial effects:

[0016] 1. This utility model designs a powder cartridge opening machine. By setting an opening support above the conveyor line, the powder cartridges to be opened are transferred to the opening support via the cartridge feeding component. After being clamped by the clamping component, the top of the cartridge is first pressed against the gap between the lid and the cartridge body, driving the top of the cartridge upwards to initially open the cartridge by 60 degrees. Then, based on this, an auxiliary opening component, under the action of the second drive component, further opens the cartridge to 90 degrees, completing the entire cartridge opening operation. This process does not affect the transmission line and achieves automated lid opening.

[0017] 2. In order to transfer multiple powder boxes to the box-opening support at the same time during the transmission process, this utility model sets a limiting strip in the middle of the transmission line. When the powder box is transmitted on the transmission line, it can be pushed to the side of the limiting strip by the box-pushing cylinder, which can ensure that multiple powder boxes are level. In this way, multiple powder boxes can be fed onto the box-opening support at the same time during the feeding process.

[0018] 3. This utility model has a guide positioning rod on the feeding side. After the powder box is pushed by the pusher cylinder until it is close to the limit stop, the powder box moves between the limit stop and the guide positioning rod, which plays a guiding role and prevents the powder box from deviating from its position during movement.

[0019] 4. This utility model incorporates a limiting cylinder and a first limiting plate and a second limiting plate. During the transport of powder boxes on the conveyor line, after a group of powder boxes is moved into position, the rightmost powder box is limited by the second limiting plate. As the other powder boxes in the group continue to move to the right, the limiting cylinder pushes out the first limiting plate, which then blocks and limits the other powder boxes. In this way, the spacing between the powder boxes is relatively fixed by the first and second limiting plates, facilitating synchronous feeding of powder boxes in the same group.

[0020] 5. In order to clamp the powder box on the box-opening support, the powder box is placed between two pairs of first partitions and at the same time, the powder box is also located between two pairs of second partitions. The clamping cylinder pushes the sliding plate to slide. During the sliding process, the second partition moves to one side relative to the strip plate. During the movement, the second partition pushes the powder box to one side until the powder box is located between the first partition and the second partition. The powder box is clamped by the first partition and the second partition, thus completing the clamping work.

[0021] 6. The driving component of this utility model can move the top of the powder box forward to the powder box position, and when the top of the powder box moves upward, it naturally drives the powder box cover to move upward, realizing a 60-degree opening operation.

[0022] 7. The purpose of this utility model's auxiliary box-opening rod is to achieve 90-degree box opening, which is achieved through the second driving component. In specific implementation, the first front and rear cylinders enable the fixed plate and the auxiliary box-opening rod on it to move back and forth. The second longitudinal cylinder can drive the first front and rear cylinders and the auxiliary box-opening rod on them to move up and down. In specific applications, the number of second longitudinal cylinders can be designed according to needs. In addition, the left and right sliding cylinders can drive the entire second longitudinal cylinder and the first front and rear cylinders to achieve overall left and right lateral movement, thus completing the lateral movement. In this way, the auxiliary box-opening rod can achieve 3 degrees of freedom of movement.

[0023] 8. This utility model provides a feeding suction cup group on the lower surface of the third support of the auxiliary box opening component. After the box is opened, the feeding suction cup group can be used to transfer the box body from the box opening support to the transmission line again, which is convenient for the next round of box opening operation.

[0024] 9. The driving component three of this utility model can realize the up-and-down and back-and-forth movement of the feeding suction cup assembly, which is achieved through the third longitudinal cylinder and the second front-and-back cylinder. The second front-and-back cylinder drives the feeding suction cup assembly to move back and forth, moving towards or away from the powder box. The third longitudinal cylinder drives the second front-and-back cylinder and the feeding suction cup assembly on it to move down as a whole, bringing the feeding suction cup assembly closer to the surface of the powder box.

[0025] 10. The fourth longitudinal cylinder designed in this utility model works in conjunction with the third longitudinal cylinder. When the downward extension distance of the third longitudinal cylinder is insufficient to reach the surface of the powder box, it can be driven by the fourth longitudinal cylinder to achieve the adaptation of the vertical distance.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] This utility model discloses a powder box opening machine, including a transmission line 1 set on a workbench, a multi-station opening support 4 fixed above the center of the transmission line 1 by a first bracket 3, a clamping component 5 sliding on the opening support 4; a powder box top 6 is set on one side of the opening support 4, facing the opening support 4, and a first driving component is connected to the powder box top 6 to drive the powder box top 6 back and forth and up and down; an auxiliary opening component 7 and a second driving component to drive the auxiliary opening component 7 left and right, back and forth and up and down are also set on the same side as the powder box top 6; a box feeding component 8 and a third driving component to drive the box feeding component 8 up and down and back and forth are set on the other side of the transmission line 1 facing the powder box top 6.

[0038] To facilitate the limiting of powder cartridge 9 on the transmission line 1, a limiting stop 201 is fixed in the middle of the transmission line 1, arranged along the direction of the transmission line 1. The cartridge to be opened is transported on the transmission line 1 between the limiting stop 201 and the cartridge feeding assembly 8, and a pusher cylinder 202 is fixed on the workbench 2 facing the limiting stop 201, and a pusher plate 203 is set at the execution end of the pusher cylinder 202. When the powder cartridge 9 passes the position where the pusher cylinder 202 and the pusher plate 203 are facing each other, the pusher cylinder 202 pushes outward, and the pusher plate 203 pushes the powder cartridge 9 closer to the limiting stop 201, so that the powder cartridge 9 moves close to the limiting stop 201.

[0039] A pair of support plates 204 are fixed on the workbench 2 located on one side of the box feeding assembly 8. A guide positioning rod 205 parallel to the limit stop 201 is fixed between the pair of support plates 204. During the transfer of the powder box 9, the powder box 9 is transferred between the guide positioning rod 205 and the limit stop 201 to prevent the powder box 9 from deviating during the transfer process.

[0040] On the workbench 2 located on one side of the cartridge feeding assembly 8, multiple limiting cylinders 208 are fixed. A first limiting plate 206 is set at the end of each limiting cylinder 208 perpendicular to the transmission line 1. A second limiting plate 207 is also fixed on the workbench 2, located to the right of the pair of first limiting plates 206, and the distance between the pair of first limiting plates 206 and second limiting plates 207 is equal. However, during the transmission of the powder cartridge 9, it is difficult to ensure the spacing between adjacent powder cartridges. Therefore, the first limiting plate 206 and the second limiting plate 207 are designed. When the powder cartridge 9 is transmitted to the far right (…),… Figure 1 When the second limit plate 207 restricts the movement of the first toner cartridge 9 in a group, and when the distance between the second toner cartridge 9 and the first toner cartridge 9 meets the requirements, the limit cylinder 208 is activated to push the first limit plate 206 to the middle position of the transmission line 1. At this time, the second toner cartridge 9 is limited by the action of the first limit plate 206. This process is repeated to fix the distance between multiple toner cartridges 9 in a group.

[0041] The box-opening support 4 includes a pair of strip plates 401 and a pair of first partitions 402 fixed at intervals on the strip plates 401. The clamping assembly 5 includes a sliding plate 501 slidably connected between the pair of strip plates 401 and matching the height of the strip plates 401. Second partitions 502 are fixed at intervals on the sliding plate 501. One end of the sliding plate 501 is set at the execution end of a clamping cylinder 503. After the powder box 9 moves up onto the box-opening support 4, each powder box 9 is located between adjacent first partitions 402, and at this time, the second partition 502 corresponds one-to-one with the first partitions 402 on the two strip plates 401. The distance between the two pairs of first partitions 402 on the strip plates 401 is slightly larger than the size of the powder box 9. After the powder box 9 is placed in place, the clamping cylinder 503 is activated to push the sliding plate 501 to slide on a slide rail. During the sliding process, the powder box 9 moves closer to the right side under the action of the sliding plate 501. Figure 1 The powder box 9 moves in the middle direction, and the second partition 502 on the sliding plate 501 pushes the powder box 9 until the powder box 9 is clamped between the first partition 402 and the second partition 502.

[0042] The driving component includes a top extension cylinder 601 and a first longitudinal cylinder 602. The top extension cylinder 601 is fixed on the second bracket 603. The first longitudinal cylinder 602 is vertically arranged and its actuating end is fixed to the second bracket 603. The actuating end of the top extension cylinder 601 is fixedly connected to the powder box top head 6.

[0043] See Figure 2The gap between the powder cartridge top 6 and the lid and body of the powder cartridge 9 is designed to match the powder cartridge top 6. The side of the powder cartridge top 6 closest to the powder cartridge 9 is flat, fitting perfectly into the gap between the powder cartridge top 6 and the lid and body of the powder cartridge 9. During operation, the first longitudinal cylinder 602 drives the second bracket 603 to move downwards. After reaching its position, the extension cylinder 601 extends the powder cartridge top 6 forward and inserts it into the corresponding position of the powder cartridge 9. To allow for adjustment in the left and right directions, the first longitudinal cylinder 602 is slidably mounted on a sliding rod 604. (See [reference]). Figure 2 The first longitudinal cylinder 602 can be locked as a whole by locking buckle 605. For powder boxes 9 of different sizes, the left and right positions of the first longitudinal cylinder 602 and the second bracket 603 on it can be adjusted appropriately according to the actual needs on site.

[0044] The auxiliary box-opening assembly 7 includes at least one auxiliary box-opening rod 701 arranged parallel to the direction of the transmission line 1, and a fixing plate 702 for fixing the auxiliary box-opening rod 701; the driving component 2 includes a first front and rear cylinder 703 matching the number of auxiliary box-opening rods 701, at least one second longitudinal cylinder 704, and a left and right sliding cylinder 705. The actuating end of the first front and rear cylinder 703 is fixedly connected to the fixing plate 702, and the actuating end of the second longitudinal cylinder 704 is fixed to a third bracket 706. The first front and rear cylinders 703 are fixed on the third bracket 706; the second longitudinal cylinder 704 is slidably arranged on a slide rail 707, and the actuating end of the left and right sliding cylinder 705 is connected to the second longitudinal cylinder 704. The lower surface of the third bracket 706 is also provided with a feeding suction cup assembly 708 matching the number of box-opening support seats 4. After the toner cartridge top 6 completes its movement, the toner cartridge 9 opens 60 degrees under the up-and-down action of the toner cartridge top 6. To further open it, the left-right sliding cylinder 705 drives the first front-rear cylinder 703, the second longitudinal cylinder 704, and the third support 706 on them to move left and right until they are in position directly opposite the cartridge opening support 4. At this point, the second longitudinal cylinder 704 is activated to move up and down, and the first front-rear cylinder 703 can be driven to move the third support 706 forward, so that the auxiliary opening rod 701 is close to the position of the toner cartridge 9. When the auxiliary opening rod 701 is located below the lid of the toner cartridge that has been opened 60 degrees, the first front-rear cylinder 703 and the second longitudinal cylinder 704 are activated to continue working until the toner cartridge 9 is opened to 90 degrees. After opening, the unloading suction cup assembly 708 is positioned directly opposite the powder box 9 after opening. The second longitudinal cylinder 704 is activated, which moves the unloading suction cup assembly 708 down to contact the powder box 9. The unloading suction cup assembly 708 is then activated to complete the adsorption operation of the powder box 9. Afterward, the powder box 9 is unloaded through the first front and rear cylinders 703, the second longitudinal cylinder 704, and the left and right sliding cylinders 705. In this embodiment, the powder box 9 is transferred to the transmission line 1 on one side for easy operation at the next station.

[0045] The box feeding assembly 8 includes a feeding suction cup group 802 connected to the box opening support 4 in number via a fourth bracket 801. The driving component three includes a third longitudinal cylinder 803 and a second front and rear cylinder 804. The fourth bracket 801 is connected to the actuating end of the third longitudinal cylinder 803, and the third longitudinal cylinder 803 is fixed to the actuating end of the second front and rear cylinder 804. The driving component three also includes a fourth longitudinal cylinder 805, the actuating end of which is fixedly connected to the second front and rear cylinder 804. In addition, to facilitate height adjustment, the entire drive unit three can be mounted on an adjustable component, and the height of the drive unit three can be adjusted as a whole via a handwheel and lead screw. This structure is a conventional technical means and will not be elaborated further here. The third longitudinal cylinder 803 and the fourth longitudinal cylinder 805 drive the second front and rear cylinders 804 and the fourth bracket 801 and the feeding suction cup group 802 mounted on them to move up and down. The second front and rear cylinders 804 drive the fourth bracket 801 and the feeding suction cup group 802 to move back and forth. When feeding is required, the feeding suction cup group 802 moves closer to the powder box 9. When the feeding suction cup group 802 contacts the powder box 9, it is activated to adsorb the powder box, and the powder box 9 is transferred by the third longitudinal cylinder 803, the fourth longitudinal cylinder 805 and the second front and rear cylinders 804 until it is transferred to the box opening support 4. The third longitudinal cylinder 803, the fourth longitudinal cylinder 805 and the second front and rear cylinders 804 return to their original positions, waiting for the next round of feeding.

[0046] Working principle:

[0047] 1. Place the powder boxes 9 one by one onto the transmission line 1 for transmission. After passing the position of the pusher cylinder (202), push the pusher plate 203 forward and push the powder box 9 to be close to the limit stop bar 201.

[0048] 2. After the powder box 9 is moved into place, the first limiting plate 206 is driven by the limiting cylinder 208 to adjust the spacing between a group of powder boxes 9 (in this embodiment, each group of powder boxes 9 has 3).

[0049] 3. Start the powder box feeding assembly 8, move the powder box 9 to the box opening support 4, and start the clamping cylinder 503 to clamp the powder box 9 between the first partition 402 and the second partition 502.

[0050] 4. Start the driving component of the powder box top head 6, drive the powder box top head 6 to approach the gap between the lid and the body of the powder box 9. During the extension process, the first longitudinal cylinder 602 drives the powder box top head 6 to move upward. At the same time as moving upward, the extension cylinder 601 extends forward, completing the 60-degree opening of the powder box 9.

[0051] 5. Start the auxiliary box opening component 7. Drive the auxiliary box opening rod 701 to approach the lid of the powder box 9 through the second drive component. Also, drive the second drive component to open the powder box 9 by 90 degrees. After opening, use the feeding suction cup group 708 to pick up the opened powder box 9 and transfer it to the transmission line 1 on the other side.
