Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, and more specifically, to a steering conveying assembly for facial mask packaging. Background Art

[0002] After a single facial mask package is filled at the filling machine, it is conveyed by the discharge conveyor to the infeed conveyor of the weighing device. The mask then moves to the weighing station via the infeed conveyor, where it is weighed and then automatically packaged in the packaging machine. However, due to production space constraints, the equipment is generally difficult to arrange in a straight line. Therefore, the conveying directions of the filling machine's discharge conveyor and the infeed conveyor of the weighing device are perpendicular to each other. Furthermore, the infeed conveyor of the weighing device is restricted by the weighing mechanism and cannot be adjusted to the same height as the infeed conveyor. As a result, there is a height difference between the two. As the mask enters the conveyor belt of the infeed conveyor, the angle between the mask and the conveyor belt is too large, close to vertical. This causes the mask to rotate randomly, resulting in the mask being off-center and unable to adjust its orientation to follow the conveying direction. This is because when a nearly vertical object is rotated to a horizontal position, the horizontal position is random and unpredictable without external intervention. Therefore, the mask's posture is difficult to control, affecting conveying and making direct weighing and packaging impossible. Utility Model Content

[0003] The purpose of the present utility model is to overcome the problem in the prior art that facial masks cannot be normally transported between two front and rear conveying devices with a height difference and perpendicular to each other, and to provide a steering conveying component for facial mask packaging, which can enable the facial mask to be smoothly transported between two conveying devices with a height difference and perpendicular to each other and to perform a certain steering position.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A steering conveying assembly for facial mask packaging is provided, comprising a first conveying device for conveying materials along a first direction, a second conveying device for conveying materials along a second direction, and a guide mechanism, wherein the feed end of the second conveying device is located below the discharge end of the first conveying device, and the first direction is perpendicular to the second direction; the guide mechanism comprises a connecting member and a guide member connected to one end of the connecting member; the other end of the connecting member is connected to the first conveying device, the guide member is located between the first conveying device and the second conveying device, and the top surface of the guide member is 2-5 mm lower than the conveying surface of the first conveying device in the vertical direction.

[0006] In the above technical solution, the first conveyor device delivers the filled facial mask, which then follows the first conveyor device in a first direction, with the bottom edge of the mask perpendicular to the first direction. When the facial mask reaches the discharge end of the first conveyor device, the bottom edge of the mask contacts the conveying surface of the second conveyor device, and the guide member contacts the bottom surface of the mask, providing support for the mask. Due to the supporting effect of the guide member, the angle between the facial mask and the conveying surface of the second conveying device is reduced. Moreover, due to the friction between the guide member and the facial mask, when the first conveying device conveys the bottom of the facial mask in the second direction, the friction between the guide member and the facial mask prevents the upper portion of the facial mask from moving in the second direction. That is, the bottom portion of the facial mask is subjected to the force in the second direction, while the upper portion of the facial mask is still subjected to the supporting force of the guide member and the force in the first direction. This causes the facial mask to slowly turn at the guide member until the entire facial mask has completely turned 90 degrees and fully entered the second conveying device, at which point it will follow the second conveying device to move in the second direction. At this time, the facial mask is in a posture with its bottom edge perpendicular to the first direction, that is, the facial mask can always maintain a posture with its bottom edge perpendicular to the conveying direction. At the same time, due to the reduced angle between the facial mask and the conveying surface of the second conveying device and the fact that the facial mask only contacts the second conveying device after the facial mask has completed its turn, the facial mask will no longer rotate randomly on the second conveying device, and the entire facial mask is located on the conveying surface of the second conveying device, so the facial mask can be controlled to be in the center area of ​​the conveying surface near the second conveying device.

[0007] Since the facial mask is a thin product, the angle between the facial mask and the conveying surface of the second conveying device can be effectively adjusted when the top surface of the guide member is 2-5 mm lower than the conveying surface of the first conveying device in the vertical direction. If it is not within this range, it is difficult for the guide member to contact the facial mask, and the supporting and guiding effects are poor.

[0008] Furthermore, the conveying surface of the first conveying device is divided into a first area and a second area along its center line, wherein the first area is close to the connecting member; the other end of the guide member extends to the bottom of the second area. When the facial mask comes out of the filling machine, it will be located in the middle of the first conveying device, generally half of it will be located in the first area and the other half will be located in the second area. The guide member must support more than half of the size of the facial mask in order to better support the facial mask and allow the facial mask to complete the turn smoothly. If the other end of the guide member is only located below the first area, the facial mask may be overhung due to too much area, and under the action of gravity and the force in the second direction applied by the second conveying device, it may flip directly from the guide member and fall to the conveying surface of the second conveying device. At this time, the facial mask has not completed the turn, and the position and posture of the fall are also uncontrollable.

[0009] Furthermore, the axis of the guide member is perpendicular to the vertical direction. When the guide member supports the mask, there will be no height difference on both sides of the mask, and the mask will not have a tendency to tilt to the sides due to the guide member. The two sides here refer to the side edges of the mask perpendicular to the bottom edge.

[0010] Furthermore, the guide member includes a fixed portion and a telescopic portion slidably connected to the fixed portion, the telescopic portion and the fixed portion being connected by a locking member; the fixed portion being connected to the connecting member. The telescopic portion can slide along the fixed portion and adjust its extension length before being fixed by the locking member. The specific position of the guide member below the second area can be adjusted, which allows for corresponding adjustment according to the size of the mask. For example, for a smaller mask, the extension length of the telescopic portion is shorter, while for a larger mask, the extension length of the telescopic portion is longer.

[0011] Furthermore, the guide member is in the shape of a round rod. The round rod can prevent the mask from being lifted up by sharp corners on the surface, which would cause the guide member and the mask to contact only at the edges, resulting in a small contact area and poor supporting effect.

[0012] Furthermore, the telescopic portion is covered with a rubber sleeve. The rubber sleeve can increase the friction between the guide member and the mask member, and can more effectively allow the mask to complete the turning at a slower speed at the guide member.

[0013] Furthermore, the locking member includes a locking sleeve mounted on an end of the fixed portion remote from the connector, and a first fastener threadedly connected to the locking sleeve and extending into the locking sleeve; the telescopic portion passes through the locking sleeve and is slidably connected to the fixed portion. The telescopic portion is locked by tightening the first fastener so that it extends into the locking sleeve and abuts against a surface of the telescopic portion.

[0014] Furthermore, the guide member is rotatably connected to the connecting member via a second fastener. The guide member can rotate relative to the connecting member and be fixed via the second fastener after the rotation. After the guide member rotates, the distance of the guide member relative to the first conveying device on the horizontal plane can be adjusted. For smaller facial masks, the time it takes to detach from the guide member will be relatively fast, and the mask may detach from the guide member before a complete turn is completed. In this case, the guide member can be rotated away from the first conveying device to extend the time the mask is supported by the guide member, allowing the mask more time to complete the turn of the entire mask.

[0015] Furthermore, the connecting member is connected to the first conveying device via a third fastener. The connecting member is provided with an elongated hole extending in a vertical direction, and the third fastener passes through the elongated hole to secure the connecting member to the first conveying device. By loosening the third fastener and adjusting the elongated hole up or down, the vertical height of the guide member can be adjusted within a height difference of 2-5 mm, allowing for adaptive adjustment according to varying mask thicknesses.

[0016] Compared with the prior art, the beneficial effect of the present invention is that: through the action of the guiding mechanism, the angle at which the facial mask contacts the conveying surface of the second conveying device becomes smaller, and under the action of the guide member, the facial mask fully enters the conveying surface of the second conveying device only after completing the turning, so that the facial mask is conveyed on the second conveying device only after the posture conversion is achieved. At this time, the posture of the facial mask is stable and is completely located on the conveying surface of the second conveying device, so that the facial mask can be stably and smoothly conveyed to the weighing mechanism and packaging device.

[0024] Example 1

[0025] This embodiment is the first embodiment of a steering conveying assembly for facial mask packaging, including a first conveying device 100 for material transmission along a first direction, a second conveying device 200 for material transmission along a second direction, and a guide mechanism. The feed end of the second conveying device 200 is located below the discharge end of the first conveying device 100, and the first direction is perpendicular to the second direction; the guide mechanism includes a connecting member 300 and a guide member 400 connected to one end of the connecting member 300; the other end of the connecting member 300 is connected to the first conveying device 100, and the guide member 400 is located between the first conveying device 100 and the second conveying device 200, and the top surface of the guide member 400 is 2-5 mm lower than the conveying surface of the first conveying device 100 in the vertical direction.

[0026] In this embodiment, the conveying surface of the first conveyor 100 is divided into a first area 110 and a second area 120 along its centerline. The first area 110 is located near the connector 300. The other end of the guide member 400 extends to below the second area 120. When the facial mask emerges from the filling machine, it is located in the middle of the first conveyor 100, generally with half located in the first area 110 and the other half in the second area 120. The guide member 400 must support more than half of the mask to effectively support it and ensure smooth turning. If the other end of the guide member 400 only lies below the first area 110, the mask may overhang excessively. Under the influence of gravity and the second-direction force exerted by the second conveyor 200, the mask may flip directly from the guide member 400 and fall onto the conveying surface of the second conveyor 200. At this point, the mask has not yet completed its turn, and its falling position and posture are uncontrollable. In this embodiment, the first conveying device 100 and the second conveying device 200 are both belt transmission conveying devices, and the conveying surfaces of the first conveying device 100 and the second conveying device 200 are conveyor belts. The guide member 400 is located above the conveyor belt of the second conveying device 200.

[0027] Furthermore, the axis of the guide member 400 is perpendicular to the vertical direction. When the guide member 400 supports the mask, there will be no height difference on both sides of the mask, and the mask will not tend to tilt to the sides due to the guide member 400. The two sides here refer to the side edges of the mask perpendicular to the bottom edge.

[0028] The working principle of the steering conveying assembly for facial mask packaging in this embodiment is as follows: Figure 3 As shown, the first conveyor 100 delivers the filled facial mask 700, which then moves in a first direction along with the first conveyor 100. At this point, the bottom edge of the facial mask 700 is perpendicular to the first direction. When the facial mask 700 reaches the discharge end of the first conveyor 100, the bottom edge of the facial mask 700 contacts the conveying surface of the second conveyor 200, and the guide member 400 contacts the bottom surface of the facial mask 700, providing support for the facial mask 700. The mask 700 is moved along the second direction by the guide member 400 and the upper portion of the mask 700 is moved along the second direction by the guide member 400. At the same time, since the angle between the facial mask 700 and the conveying surface of the second conveying device 200 is reduced and the facial mask 700 only contacts the second conveying device 200 after completing the turning, the facial mask 700 will no longer rotate randomly on the second conveying device 200, and the entire facial mask 700 is located on the conveying surface of the second conveying device 200, the facial mask 700 can be controlled in the central area of ​​the conveying surface close to the second conveying device 200.

[0029] Since facial masks are thin products, the angle between the facial mask and the conveying surface of the second conveying device 200 can be effectively adjusted when the top surface of the guide member 400 is 2-5 mm lower than the conveying surface of the first conveying device 100 in the vertical direction. If it is not within this range, it is difficult for the guide member 400 to contact the facial mask, and the supporting and guiding effects are poor.

[0030] The beneficial effects of this embodiment are as follows: through the action of the guiding mechanism, the angle at which the facial mask contacts the conveying surface of the second conveying device 200 becomes smaller, and under the action of the guide member 400, the facial mask fully enters the conveying surface of the second conveying device 200 only after completing the turning, so that the facial mask is conveyed on the second conveying device 200 only after the posture conversion is achieved. At this time, the posture of the facial mask is stable and is completely located on the conveying surface of the second conveying device 200, so that the facial mask can be stably and smoothly conveyed to the weighing mechanism and packaging device.

[0031] Example 2

[0032] This embodiment is the second embodiment of the steering and conveying assembly for facial mask packaging. This embodiment is similar to the first embodiment, except that the guide mechanism is further limited.

[0033] Specifically, the guide member 400 includes a fixed portion 410 and a telescopic portion 420 slidably connected to the fixed portion 410. The telescopic portion 420 and the fixed portion 410 are connected by a locking member 430. The fixed portion 410 is connected to the connecting member 300. The telescopic portion 420 can slide along the fixed portion 410 and adjust its extension length before being fixed by the locking member 430. The specific position of the guide member 400 below the second area 120 can be adjusted, which can be adjusted accordingly according to the size of the facial mask. For example, for a smaller facial mask, the telescopic portion 420 extends shorter, while for a larger facial mask, the telescopic portion 420 extends longer.

[0034] In this embodiment, the guide member 400 is in the shape of a round rod. This prevents sharp corners on the surface from lifting the mask, which would otherwise result in the guide member 400 contacting the mask at the edge, resulting in a small contact area and poor support. The telescopic portion 420 is covered with a rubber sleeve. The rubber sleeve increases the friction between the guide member 400 and the mask, allowing the mask to more effectively turn at a slower speed around the guide member 400.

[0035] In this embodiment, the locking member 430 includes a locking sleeve 431 mounted on the end of the fixed portion 410 away from the connector 300, and a first fastener 432 threadedly connected to the locking sleeve 431 and extending into the locking sleeve 431. The telescopic portion 420 passes through the locking sleeve 431 and is slidably connected to the fixed portion 410. Tightening the first fastener 432 causes it to extend into the locking sleeve 431 and abut against the surface of the telescopic portion 420, thereby locking the telescopic portion 420.

[0036] In this embodiment, the guide member 400 is rotatably connected to the connecting member 300 via a second fastener 500. The guide member 400 can rotate relative to the connecting member 300 and be fixed by the second fastener 500 after rotation. After the guide member 400 rotates, the distance of the guide member 400 relative to the first conveying device 100 on the horizontal plane can be adjusted. For smaller facial masks, the time it takes to separate from the guide member 400 will be relatively fast, and it may separate from the guide member 400 before completing a complete turn. In this case, the guide member 400 can be rotated away from the first conveying device 100 to extend the time the facial mask is supported by the guide member 400, allowing the facial mask more time to complete the entire turn.

[0037] The remaining features and working principles of this embodiment are consistent with those of the above embodiment 1.

[0038] Example 3

[0039] This embodiment is the third embodiment of a steering conveyor assembly for facial mask packaging. This embodiment is similar to the second embodiment, differing in that the connector 300 is connected to the first conveyor 100 via a third fastener 600. The connector 300 is provided with an elongated hole extending in the vertical direction, through which the third fastener 600 passes to secure the connector 300 to the first conveyor 100. By loosening the third fastener 600 and adjusting the elongated hole up or down, the vertical height of the guide member 400 can be varied, allowing adjustment within a range of 2-5 mm. This allows for adaptive adjustment based on the thickness of the facial mask.

[0040] The remaining features and working principles of this embodiment are consistent with any of the above embodiments.

[0041] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
