Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a conveying mechanism of a soft bag vacuum helium mass spectrometer leak detector. Background Art

[0002] With the continuous development of pharmaceutical packaging materials, the glass bottle infusion currently widely used in production is gradually replaced by disposable soft-package infusion bags. Because soft-bag packaging has large deformation and many dead corners, leakage detection of soft-bag packaging has become a difficult point in production. As a key system in leakage detection, the conveying system determines the key to detection effect and efficiency of specification change.

[0003] The inspection of soft-packaged infusion bags adopts conveyor belt through-type inspection, which is to place the packaging bag on the inspection mold of the conveying mechanism, and after the mass spectrometer inspection, the qualified and unqualified products are grabbed by the manipulator on the equipment at the unloading end and placed in their corresponding placement areas. However, during the movement of the traditional conveying mechanism, the inspection mold has a large turning radius, and the inspection mold is completely turned over as a whole, which generates a large inertial impact force and occupies a large space. Utility Model Content

The two driven guide sprockets are respectively arranged at the front ends of the two sprockets at the feeding end, so that the supporting rollers on both sides of the rotating conveying mold plate toward the upper feeding end position enter the tooth grooves of the two driven guide sprockets along the supporting track respectively when they rotate. The two driven guide sprockets are connected by a driven transmission shaft, and the driven guide sprocket is connected to the transmission shaft of the sprocket at the feeding end through the upward chain transmission mechanism. The upward guide seat is located below the driven transmission shaft, so that the conveying mold plate rotating toward the upper feeding end is lifted up through the cooperation of the upward guide wheel and the upward guide surface.

[0008] Furthermore, the distance from the axis between the active guide sprocket and the driven auxiliary guide wheel to the active shaft at the unloading end is equal to the distance from the supporting roller on the conveying mold plate to the connecting piece, and the distance from the axis between the driven transmission shaft between the two driven guide sprockets to the two sprockets at the loading end is also equal to the distance from the supporting roller on the conveying mold plate to the connecting piece.

DETAILED DESCRIPTION

[0025] Example 1

[0026] The following is further described with reference to the accompanying drawings. Figure 1-3 As shown, a conveying mechanism of a soft bag vacuum helium mass spectrometer leak detector is provided, including two main chain transmission mechanisms 1 and a plurality of conveying mold plates 2, wherein two sprockets at the unloading end are connected by a driving shaft 100, and the plurality of conveying mold plates 2 are arranged on the two main chain transmission mechanisms 1 to form a traditional conveying mechanism body, which is different from the main part of the traditional conveying mechanism, and an upward guide wheel 200 is arranged on the lower surface of the conveying mold plate 2, and the conveying mold plate 2 is respectively equipped with support rollers 3 on both sides of the front end, and is fixedly installed on the chain of the main chain transmission mechanism 1 by connecting members 4 on both sides of the rear end, and a support track 8 for supporting the rolling of the support roller 3 is arranged below the path of the support roller 3 for advancing and rotating, and a downward template guide mechanism 5 and an upward template guide mechanism 6 are respectively arranged at the unloading end and the loading end of the conveying mechanism body along the advancing direction of the conveying mold plate 2,

[0027] With regard to the design of the support track 8, the support track 8 includes a forward section track and a rotary section track 800. The forward section track is located on the path of the support roller 3 when the conveying mold plate 2 is advancing, and the rotary section track 800 is located on the path of the support roller 3 when the conveying mold plate 2 is rotating. The forward section track includes a first forward track 801 and a second forward track 802. The first forward track 801 is located between the loading end and the unloading end of the conveying mechanism body, and the second forward track 801 is located between the unloading end and the downward template guide mechanism 5. Due to the presence of a trackless area between the first forward track 801 and the second forward track 802, a forward support wheel 7 is provided below the conveying mold plate 2 at the unloading end to support the front end of the conveying mold plate 2 to pass through the trackless area. The forward support wheel 7 is provided on the fixed plate 803. The first forward track 801, the second forward track 802, the rotary section track 800 and the fixed plate 803 are fixed on the equipment frame, and the equipment frame is not shown in the drawings of this embodiment.

[0028] With regard to the design of the downward template guide mechanism 5, the downward template guide mechanism includes an active guide sprocket 500, a driven auxiliary guide wheel 501 and a downward chain transmission mechanism 502. The active guide sprocket 500 and the driven auxiliary guide wheel 501 are respectively arranged at the front ends of the two sprockets at the unloading end, so that when the support rollers 3 on both sides of the conveying mold plate 2 located at the unloading end position move forward, they enter the tooth grooves of the active guide sprocket 500 and the guide surface of the driven auxiliary guide wheel 501 along the support track 8 respectively. The distance between the axis between the active guide sprocket 500 and the driven auxiliary guide wheel 501 and the driving shaft 100 at the unloading end is equal to the distance from the support roller 3 on the conveying mold plate 2 to the connecting piece 4, ensuring that the conveying mold plate 2 has sufficient The driving guide sprocket 500 and the driven auxiliary guide wheel 501 are both equipped with supporting shafts 503. The supporting shafts 503 on the driving guide sprocket 500 are connected to the driving shaft 100 on the main chain transmission mechanism 1 through the downward chain transmission mechanism 502, so that the driving guide sprocket 500 is synchronized with the two sprockets at the feeding end and the two sprockets at the unloading end. The outer side of the gear groove in the downward direction of the driving guide sprocket 500 and the outer side of the guide surface in the downward direction of the driven auxiliary guide wheel 501 are provided with a track constraint plate 504 for limiting the running track of the support roller 3. The track constraint plate 504 is fixed on the equipment frame, and the equipment frame is not shown in the drawings of this embodiment.

[0029] With regard to the design of the upward template guide mechanism 6, the upward template guide mechanism 6 includes two driven guide sprockets 600, an upward chain transmission mechanism 601 and an upward guide seat 602. The two driven guide sprockets 600 are respectively arranged at the front ends of the two sprockets at the feeding end, so that the support rollers 3 on both sides of the conveying mold plate 2 rotating toward the upper feeding end position enter the tooth grooves of the two driven guide sprockets 600 along the support track 8 respectively. The two driven guide sprockets 600 are connected by a driven transmission shaft 603. The axial distance between the driven transmission shaft 603 of the two driven guide sprockets 600 and the two sprockets at the feeding end is equal to the distance from the support rollers 3 on the conveying mold plate 2 to the connecting piece 4, ensuring that the conveying mold plate 2 has enough translation distance for rotation. The guide sprocket 600 is connected to the transmission shaft of the sprocket at the feeding end through the upward chain transmission mechanism 601, so that the driven guide sprocket 600 is synchronized with the two sprockets at the feeding end and the two sprockets at the unloading end. The upward guide seat 602 is located below the driven transmission shaft 603. The contact surface between the upward guide seat 602 and the upward guide wheel 200 is the upward guide surface, so that the conveying mold plate 2 that rotates to the upper feeding end is lifted up through the cooperation between the upward guide wheel 200 and the upward guide surface. The upward guide seat 602 is fixed on the equipment frame. The equipment frame is not shown in the drawings of this embodiment. The upward chain transmission mechanism 601 and the aforementioned downward chain transmission mechanism 502 both adopt traditional chain transmission mechanisms, that is, the chain drives the sprocket on the rotating shaft to transmit, which will not be repeated here.

[0030] like Figure 4 As shown, in order to apply this embodiment to the equipment frame, mounting plates 9 for fixing to the equipment frame are installed on both ends of the driving shaft 100 at the unloading end of the conveying mechanism body, on the rotating shaft of the sprocket at the loading end, on both ends of the driven transmission shaft 603 connecting the two driven guide sprockets 600, and on the supporting rotating shaft 503 of the driving guide sprocket 500 and the driven auxiliary guide wheel 501.

[0031] Working principle, during transmission, such as Figure 5-6 As shown, the rear end of the conveying mold plate 2 is fixed to the chain of the main chain transmission mechanism 1 through a connecting piece 4, and the front end of the conveying mold plate 2 is on the support track 8 through the support roller 3, so the conveying mold plate 2 runs smoothly under the drive of the main chain transmission mechanism 1. When the conveying mold plate 2 advances to the unloading end, the support roller 3 at the front end of the conveying mold plate 2 breaks away from a forward track, but under the action of the forward support wheel 7, the front end of the conveying mold plate 2 still advances smoothly through the trackless area and enters the second forward track 802. Since the active guide sprocket 500 is synchronized with the sprocket of the main chain transmission mechanism 1, the two support rollers 3 at the front end of the conveying mold plate 2 can smoothly enter the tooth groove of the active guide sprocket 500 and the guide surface of the driven auxiliary guide wheel 501 respectively. As the rear end of the conveying mold plate 2 is driven by the chain of the unloading end to rotate downward, the front end of the conveying mold plate 2 is synchronously downward through the active guide sprocket 500 and the driven auxiliary guide wheel 501, and the downward template guide mechanism 5 completes the downward rotation of the conveying mold plate 2.

[0032] like Figure 7-9 As shown, the conveying mold plate 2 rotates and moves forward in the opposite direction. At this time, the fixed connection point between the rear end of the conveying mold plate 2 and the chain of the main chain transmission mechanism 1 is in front, and the support roller 3 at the front end of the conveying mold plate 2 is at the back. At this time, the support roller 3 rotates and moves forward on the rotating section track. When the rear end of the conveying mold plate 2 reaches the loading end position, as the rear end of the conveying mold plate 2 is driven by the chain of the loading end to rotate and rise, the conveying mold plate 2 is gradually and synchronously lifted up through the cooperation of the upward guide wheel 200 and the upward guide surface. Since the two driven guide sprockets 600 are synchronized with the sprockets of the main chain transmission mechanism 1, the two support rollers 3 at the front end of the conveying mold plate 2 can respectively enter the tooth grooves of the two driven guide sprockets 600, and the driven guide sprocket 600 cooperates with the front end of the conveying mold plate 2 to synchronously ascend, and the upward template guide mechanism 6 completes the upward rotation of the conveying mold plate 2.
