Description

Technical Field

[0001] This utility model belongs to the field of conveyor technology, specifically a double-chamber bag conveyor. Background Technology

[0002] A double-chamber bag conveyor is a mechanical device used to transport powder-liquid double-chamber bags. A powder-liquid double-chamber bag is a packaging form in which powdered drugs and injectable solvents are packaged separately in two independent chambers of the same bag. During use, the two substances are connected and mixed through a specific method. The function of the conveyor is to transport the double-chamber bags in the production process, so that the double-chamber bags are transported from one production station to the next, realizing an automated production process.

[0003] In existing technologies, double-chamber bags are usually conveyed by conveyor belts. However, due to the use of soft packaging materials such as composite films, they are fragile and easily affected by external forces. During the conveying process, due to factors such as equipment vibration and the shift of the double-chamber bag's own center of gravity, the double-chamber bag is prone to deviating to both sides of the conveyor belt, which in turn causes continuous friction with the fixed baffles on both sides of the conveyor belt. This friction can lead to wear on the bag surface, cracking of the sealing edge, and even leakage or intrusion of external contaminants, resulting in product scrapping. To address this, we propose a double-chamber bag conveyor. Utility Model Content

[0004] The purpose of this invention is to provide a double-chamber bag conveyor to solve the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-chamber bag conveyor, comprising a frame and a conveyor belt mounted on the frame, wherein blocking mechanisms are provided on both sides of the top of the frame, and the blocking mechanisms include:

[0006] The upper drive wheel, the upper driven wheel, and the blocking belt fitted between the upper drive wheel and the upper driven wheel are rotated and positioned above the frame to block and limit the movement of the double-chamber bag conveyed on the conveyor belt.

[0007] An upper plate is provided above the blocking belt, and a left rotating rod and a right rotating rod are fixedly installed on the top of the upper driving wheel and the upper driven wheel, respectively.

[0008] Preferably, a crossbar is rotatably arranged above the upper drive wheel, two sets of upper bevel gears are arranged on the outside of the crossbar, and a lower bevel gear is fixedly arranged on the outside of the left rotating rod.

[0009] Preferably, a fixing ring is fixedly provided on one side of the upper bevel gear, and a locking bolt is provided on the fixing ring. A reduction motor is provided at the end of the crossbar for driving the crossbar to rotate.

[0010] Preferably, two sets of L-shaped plates are fixedly provided on both sides of the frame, and an extension plate is fixedly provided on the side of the upper plate.

[0011] Preferably, the L-shaped plate has a locking screw connected to its interior by a thread.

[0012] Preferably, one end of the upper plate is provided with a movable component, the movable component including a bearing sleeved on the outside of the right rotating rod, a threaded groove ring fixedly provided on the outside of the bearing, and two sets of threaded rings connected to the outside of the threaded groove ring by threads.

[0013] Preferably, the frame has a main rotating column and a slave rotating column rotatably mounted inside.

[0014] Preferably, an active motor is fixedly installed on the side of the frame, and the working end of the active motor is fixedly connected to the active column.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) Through the design of the blocking mechanism, the blocking belt and the conveyor belt operate synchronously. When the double-chamber bag deviates to both sides due to vibration or center of gravity shift, there is no relative sliding between the blocking belt and the double-chamber bag at the moment of contact. The contact of the flexible blocking belt replaces the rigid friction of the traditional fixed baffle. At the same time, the material of the blocking belt is food-grade rubber, which further reduces the risk of scratching during contact. The distance between the two sets of blocking belts can be adjusted by the extension plate moving along the L-shaped plate to adapt to double-chamber bags of different widths.

[0017] (2) The present invention can control the tension of the blocking belt by designing a moving part. When the blocking belt becomes loose due to long-term use, the upper driven wheel moves away from the upper driving wheel, which can quickly tighten the belt. If the belt is too tight, the tension can be reduced by adjusting in the opposite direction. This can ensure that the blocking belt always maintains a suitable tension and ensure the reliability of long-term operation. Attached Figure Description

Detailed Implementation

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Example 1

[0028] Please see Figures 1-7 This utility model provides a technical solution: a double-chamber bag conveyor, including a frame 100, a conveyor belt 101 mounted on the frame 100, and blocking mechanisms on both sides of the top of the frame 100, the blocking mechanisms including:

[0029] The upper drive wheel 205, the upper driven wheel 210, and the blocking belt 200 sleeved between the upper drive wheel 205 and the upper driven wheel 210 are rotatably arranged above the frame 100 to block and limit the double-chamber bags conveyed on the conveyor belt 101. The upper drive wheel 205 drives the blocking belt 200 to rotate, which in turn drives the upper driven wheel 210 to rotate. The rotation speed of the blocking belt 200 is synchronized with the speed of the conveyor belt 101, forming a flexible block on both sides of the double-chamber bags when they are conveyed on the conveyor belt 101. There is no relative sliding when the blocking belt 200 contacts the double-chamber bags, avoiding the friction and wear caused by the traditional fixed baffle.

[0030] An upper plate 203 is provided above the blocking belt 200. The top of the upper driving wheel 205 and the upper driven wheel 210 are respectively fixedly provided with a left rotating rod and a right rotating rod 209, and the top of the left rotating rod and the right rotating rod 209 both pass through the interior of the upper plate 203. A blocking plate 204 is fixedly provided at the bottom of the upper plate 203. The blocking plate 204 at the bottom of the upper plate 203 can limit the blocking belt 200, increase the stability of the blocking belt 200 during operation, and ensure the stability of the conveying process.

[0031] A crossbar 201 is rotatably mounted above the upper drive wheel 205. Two sets of upper bevel gears 211 are mounted on the outside of the crossbar 201. A lower bevel gear 212 is fixedly mounted on the outside of the left rotating rod. The upper bevel gears 211 and the lower bevel gears 212 mesh with each other.

[0032] Example 2

[0033] Please refer to Example 1. Figures 1-6 A fixing ring 213 is fixedly provided on one side of the upper bevel gear 211. A locking bolt 214 is provided on the fixing ring 213. Loosening the locking bolt 214 can move the fixing ring 213 on the crossbar 201 to adjust its position. The working end of the locking bolt 214 extends to the surface of the crossbar 201. A reduction motor 206 is provided at the end of the crossbar 201. The working end of the reduction motor 206 drives the crossbar 201 to rotate. A left L-shaped frame and a right L-shaped frame are fixedly provided at the top of one end of the frame 100. The reduction motor 206 is fixed on the right L-shaped frame, and one end of the crossbar 201 is rotatably set on the left L-shaped frame.

[0034] Two sets of L-shaped plates 102 are fixedly installed on both sides of the frame 100. An extension plate 207 is fixedly installed on the side of the upper plate 203, and the end of the extension plate 207 passes through the interior of the L-shaped plate 102. The extension plate 207 on the side of the upper plate 203 passes through the interior of the L-shaped plate 102 and can move along the interior of the L-shaped plate 102, thereby driving the upper plate 203 and the connected blocking mechanism (upper drive wheel 205, blocking belt 200, etc.) to adjust the position as a whole.

[0035] The L-shaped plate 102 is internally connected to a locking screw 208 via a thread. The locking screw 208 can fix the extension plate 207, and the bottom working end of the locking screw 208 extends to the surface of the extension plate 207.

[0036] Example 3

[0037] Please refer to Example 2. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7A movable component is provided at one end of the upper plate 203. The movable component can adjust the tension of the conveyor belt 101 by moving the position of the upper driven wheel 210. The movable component includes a bearing 300 sleeved on the outside of the right rotating rod 209. The bearing 300 is composed of an inner ring and an outer ring. The inner ring is fixedly connected to the right rotating rod 209, and the outer ring is fixedly connected to the threaded groove ring. The threaded groove ring is fixedly provided on the outside of the bearing 300. Two sets of threaded rings 301 are threadedly connected to the outside of the threaded groove ring. Rotating the threaded rings 301 loosens them, and then pushes the right rotating rod 209 to move away from or towards the upper driving wheel 205. This causes the right rotating rod 209 and the upper driven wheel 210 to move closer to or away from the upper driving wheel 205, thereby adjusting the tension of the conveyor belt 101 and realizing the tension adjustment of the blocking belt 200.

[0038] In this embodiment, a main rotating column and a slave rotating column are rotatably arranged inside the frame 100, and a conveyor belt 101 is sleeved on the outer surface of the main rotating column and the slave rotating column.

[0039] In this embodiment, an active motor is fixedly installed on the side of the frame 100. The working end of the active motor is fixedly connected to the active column. The controller (such as a PLC controller) is connected to the driver of the drive motor and the reducer motor 206 respectively. Encoders are installed on the output shafts of the drive motor and the reducer motor 206 to collect the motor speed data in real time and feed the data back to the controller. After receiving the data fed back by the encoder, the controller compares the speed of the drive motor and the reducer motor 206, calculates the speed difference between the two, and adjusts the speed of the reducer motor 206 according to the calculated speed difference to maintain the synchronous state of the conveyor belt 101 and the blocking belt 200.

[0040] Working principle and usage process of this utility model:

[0041] When this utility model is in use, the active motor starts when the equipment is running, which drives the main rotating column to rotate, causing the conveyor belt 101 sleeved on the main rotating column and the secondary rotating column to rotate, thereby driving the double-chamber bag to move and be conveyed.

[0042] Simultaneously, the reduction motor 206 is turned on. The working end of the reduction motor 206 rotates, which drives the crossbar 201 to rotate. The crossbar 201 drives the upper bevel gear 211, the lower bevel gear 212 meshing with it, and the left rotating rod to rotate. The left rotating rod drives the blocking belt 200 to rotate. The blocking belt 200 drives the upper driven wheel 210 and the right rotating rod 209 to rotate. At this time, the rotation speed and direction of the blocking belt 200 are the same as those of the conveyor belt 101. When the double-chamber bag conveyed on the conveyor belt 101 deviates to both sides of the conveyor belt 101, the blocking belt 200, which rotates synchronously with the conveyor belt 101, can contact the outer wall of the deviated double-chamber bag to form a flexible barrier on both sides, which will not cause wear to the double-chamber bag.

[0043] To accommodate double-chamber bags of different widths, loosen the locking screw 208 on the L-shaped plate 102, unscrew the locking bolt 214, and then push the extension plate 207 on the side of the upper plate 203 to move left or right within the L-shaped plate 102, causing the upper plate 203, the blocking belt 200, etc. to move along with it. Once the movement is complete, the distance between the two sets of blocking belts 200 can be adjusted. At the same time, the two sets of upper bevel gears 211 will move along with the movement of the upper plate 203, causing the fixing ring 213 to move. Once the movement is complete, tighten the locking screw 208 again to fix the extension plate 207, and tighten the locking bolt 214 to fix the fixing ring 213 on the upper bevel gear 211 to the crossbar 201. At this time, the upper bevel gear 211 and the lower bevel gear 212 will continue to be meshed. Then, the distance between the two sets of blocking belts 200 can be adjusted according to the width of the double-chamber bag.

[0044] When it is necessary to adjust the tension of the conveyor belt 101, rotate and loosen the two sets of threaded rings 301 on the right-hand lever 209 at one end of the upper plate 203 (the two sets of threaded rings 301 are far apart from each other). Then move the right-hand lever 209 towards or away from the crossbar 201, which will drive the upper driven wheel 210 below to move accordingly. This will allow the conveyor belt 101 to be opened or tightened. After that, rotate the two sets of threaded rings 301 towards each other to tighten them. Then adjust the position of the upper driven wheel 210 to ensure that the tension of the blocking belt 200 is appropriate.

[0045] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
