A conveyor for bagging medicine bottles

Abstract

This utility model discloses a conveyor for bagging medicine bottles, relating to the field of conveyor technology. It includes a machine body and two main belts. A negative pressure limiting mechanism is provided on the machine body. This mechanism includes a secondary belt and a long box disposed between the two main belts. Multiple negative pressure ports are evenly distributed along the length of the secondary belt to limit the movement of the medicine bottles during transport. This utility model, through its designed negative pressure limiting mechanism, uses the negative pressure ports to adhere to the bottom of the medicine bottle for positioning, replacing the direct friction between the traditional mechanical baffle and the outer wall of the bottle. This avoids wear on the bottle surface and is particularly suitable for medicine bottle packaging where appearance is critical. Simultaneously, the negative pressure adsorption force fixes the bottom of the bottle, effectively overcoming the rotation and displacement problems caused by irregular shapes, uneven weight, or belt speed fluctuations, ensuring the bagging machine accurately aligns with the bottle and improving bagging precision.

Description

Technical Field

[0001] This utility model belongs to the field of conveyor technology, specifically a conveyor for bagging medicine bottles. Background Technology

[0002] Currently, automatic bagging machines have been widely used in many fields such as food, chemical, and pharmaceutical. They mainly consist of a feeding system, a bagging system, a sealing system, and a control system. The feeding system transports the medicine bottles to be packaged to the position below the bagging system via the main belt on the conveyor. The bagging system completes the automatic bag insertion and sorting. The sealing system heat-seals or cold-seals the bags to ensure sealing quality.

[0003] In existing technologies, traditional conveyors transport medicine bottles via a main belt. To prevent bottles from tipping over, mechanical baffles are used to limit their movement. However, when packaging bottles with high appearance requirements, the outer wall of the moving bottle comes into contact with the surface of the mechanical baffle during the limiting process, causing friction and wear on the bottle's outer wall. Furthermore, during the bagging process, uneven bottle shape and weight distribution, unstable main belt speed, and fluctuations can cause the bottles to rotate during transport. This rotation can lead to positional shifts, making it difficult for the bagging machine to accurately align the bottles, thus reducing bagging accuracy. To address these issues, we propose a conveyor for bagging medicine bottles. Utility Model Content

[0004] The purpose of this utility model is to provide a conveyor for bagging medicine bottles to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveyor for bagging medicine bottles, comprising a machine body and two main belts, wherein a negative pressure limiting mechanism is provided on the machine body, the negative pressure limiting mechanism comprising:

[0006] The auxiliary belt and the long box are located between the two main belts. Multiple negative pressure ports are evenly distributed on the auxiliary belt along its length to limit the movement of the medicine bottles during transport.

[0007] A U-shaped sealing gasket is fixedly installed on the top of the long box to increase the sealing performance between the long box and the secondary belt.

[0008] The long box has trays fixedly installed on both the front and back, and a telescopic ring is fixedly installed on the negative pressure port to increase the sealing performance between the negative pressure port and the medicine bottle.

[0009] Two connecting pipes are fixedly installed at the bottom of the long box, and an outer pipe is fixedly installed at the end of the connecting pipe, and a T-shaped pipe is fixedly installed on the outer pipe.

[0010] Two studs are fixedly installed on the surface of the tray, and a threaded ring is threadedly connected to the outside of the studs.

[0011] A filter assembly is provided on the three-way pipe. The filter assembly includes a dust collection box fixed on the three-way pipe. A partition is fixedly provided inside the dust collection box, and a filter screen is fixedly provided on the partition.

[0012] The filter screen is fixedly equipped with a mounting bearing, the inner wall of the mounting bearing is provided with a rotating rod, the outside of the rotating rod is fixedly equipped with two vertical brushes, and the end of the rotating rod is fixedly equipped with a fan blade.

[0013] Both ends of the machine body are rotatably equipped with rotating shafts, and a geared motor is installed on the back of the machine body.

[0014] Two support frames are fixedly installed at the bottom of the machine body.

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

[0016] (1) This utility model uses a negative pressure limiting mechanism to limit the bottom of the medicine bottle by adsorbing it through the negative pressure port, replacing the direct friction between the traditional mechanical baffle and the outer wall of the medicine bottle, thus avoiding wear on the surface of the medicine bottle. It is especially suitable for medicine bottle packaging with high appearance requirements. At the same time, the negative pressure adsorption force is used to fix the bottom of the medicine bottle, effectively overcoming the rotation and displacement problems caused by irregular shape, uneven weight or belt speed fluctuation of the medicine bottle, ensuring that the bagging machine accurately aligns with the position of the medicine bottle, improving the bagging accuracy. The U-shaped sealing gasket on the long box can adjust the contact force between it and the auxiliary belt according to the weight of the medicine bottle, adapting to the conveying needs of medicine bottles of different weights.

[0017] (2) Through the design of the filter components, the filter screen can intercept dust and impurities in the air and prevent them from entering the negative pressure mechanism. This avoids blockage of the negative pressure port caused by impurities, ensuring the stability and continuity of the negative pressure adsorption function. When the negative pressure airflow passes through the three-way pipe, the fan blade drives the rotating rod and vertical brush to rotate, automatically cleaning the attachments on both sides of the filter screen. No manual disassembly and cleaning is required, maintaining the air permeability of the filter screen and ensuring the efficient operation of the system. Attached Figure Description

Detailed Implementation

[0028] 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.

[0029] Example 1

[0030] Please see Figures 1-8This utility model provides a technical solution: a conveyor for bagging medicine bottles, in which the negative pressure of the negative pressure port 207 can be adjusted by adjusting the negative pressure of the negative pressure pump during use. Different negative pressures are applied to limit the movement of medicine bottles of different specifications and weights. The conveyor includes a body 100 and two main belts 101. A negative pressure limiting mechanism is provided on the body 100, and a lower plate 209 is installed on the body 100. The negative pressure limiting mechanism includes a secondary belt 200 disposed between the two main belts 101 and a long box 2. 08. The main belt 101 is in contact with the two auxiliary belts 200 but not connected. Multiple negative pressure ports 207 are evenly distributed on the auxiliary belts 200 along their length for limiting the movement of the medicine bottles during transport. The auxiliary belts 200 are fitted between the two sets of rotating shafts 102. Both the auxiliary belts 200 and the spiral seals 212 are wear-resistant to reduce friction and wear between them.

[0031] A U-shaped sealing gasket 212 is fixedly installed on the top of the long box 208. During the rotation and transportation of the auxiliary belt 200, the inner wall comes into contact with the surface of the U-shaped sealing gasket 212 to increase the sealing performance between the long box 208 and the auxiliary belt 200.

[0032] The front and back of the long box 208 are fixedly provided with a support plate 206. The support plate 206 can support the main belt 101 and prevent the main belt 101 from sagging when it is suspended in the air during rotation. A telescopic ring 211 is fixedly provided on the negative pressure port 207. When the medicine bottle is placed on the negative pressure port 207, the bottom of the medicine bottle contacts the telescopic ring 211 on the negative pressure port 207. At this time, the telescopic ring 211 is compressed by the pressure of the medicine bottle, which increases the sealing between the negative pressure port 207 and the bottom of the medicine bottle, thereby increasing the negative pressure limiting effect on the medicine bottle and increasing the sealing performance between the negative pressure port 207 and the medicine bottle.

[0033] Two connecting pipes 210 are fixedly installed at the bottom of the long box 208. An outer pipe 201 is fixedly installed at the end of the connecting pipe 210. A three-way pipe 202 is fixedly installed on the outer pipe 201. A first valve 213 and a second valve 214 are respectively installed on the three-way pipe 202. The first valve 213 is connected to an external negative pressure pump to generate negative pressure at the negative pressure port 207. The second valve 214 is connected to an external blower to generate outward airflow at the negative pressure port 207.

[0034] Two studs 205 are fixedly installed on the surface of the tray 206. Two adjustment slots 204 are opened on the front and back of the machine body 100. The end of the stud 205 passes through the interior of the adjustment slot 204. The outside of the stud 205 is connected to a threaded ring 203 by a thread. In use, the contact force between the U-shaped sealing gasket 212 on the top of the long box 208 and the auxiliary belt 200 above can be adjusted as needed. When adjusting, the threaded ring 203 is rotated outward to loosen it. Then the stud 205 is moved up or down to a suitable position, which drives the height position of the tray 206, the long box 208 and the U-shaped sealing gasket 212 on the top of the long box 208 to be adjusted. Then the threaded ring 203 is rotated towards the machine body 100 to tighten it.

[0035] This utility model utilizes a designed negative pressure limiting mechanism, which uses the negative pressure port 207 to adsorb and limit the bottom of the medicine bottle, replacing the direct friction between the traditional mechanical baffle and the outer wall of the medicine bottle. This avoids wear on the surface of the medicine bottle and is especially suitable for medicine bottle packaging with high appearance requirements. At the same time, the negative pressure adsorption force fixes the bottom of the medicine bottle, effectively overcoming the rotation and displacement problems caused by irregular shape, uneven weight, or belt speed fluctuations of the medicine bottle. This ensures that the bagging machine accurately aligns with the position of the medicine bottle and improves the bagging accuracy. The U-shaped sealing gasket 212 on the long box 208 can adjust the contact force between itself and the auxiliary belt 200 according to the weight of the medicine bottle, adapting to the conveying needs of medicine bottles of different weights.

[0036] Example 2

[0037] Please refer to Example 1. Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 8 and Figure 9 A filter assembly is provided on the three-way pipe 202. The filter assembly includes a dust collection box 300 fixed on the three-way pipe 202. A top plate 301 is fixed to the top of the dust collection box 300 by bolts. The top plate 301 can be opened to clean the impurities or dust accumulated in the dust collection box 300. A partition 304 is fixedly provided inside the dust collection box 300. A filter screen 303 is fixedly provided on the partition 304 to filter the impurities that pass through.

[0038] The filter screen 303 has a mounting bearing fixedly installed inside. The inner wall of the mounting bearing is equipped with a rotating rod 302. Two vertical brushes 306 are fixedly installed on the outside of the rotating rod 302. When air is generated in the three-way pipe 202, it will drive the fan blade 305 to rotate. The fan blade 305 drives the rotating rod 302 and the vertical brushes 306 to rotate. The two sets of vertical brushes 306 remove the impurities attached to the two surfaces of the filter screen 303 to avoid clogging the filter screen 303. The fan blade 305 is fixedly installed at the end of the rotating rod 302.

[0039] This utility model, through its designed filter components, allows the filter screen 303 to intercept dust and impurities in the air, preventing them from entering the negative pressure mechanism (such as the long box 208, connecting pipe 210, etc.), thus avoiding blockage of the negative pressure port 207 due to impurities. This ensures the stability and continuity of the negative pressure adsorption function. When the negative pressure airflow passes through the three-way pipe 202, the fan blade 305 drives the rotating rod 302 and the vertical brush 306 to rotate, automatically cleaning the adhering substances on both sides of the filter screen 303 (impurities adhere to the back of the filter screen 303 under negative pressure and to the front under positive pressure). This eliminates the need for manual disassembly and cleaning, maintains the air permeability of the filter screen 303, and ensures efficient system operation.

[0040] In this embodiment, rotating shafts 102 are rotatably provided at both ends of the machine body 100, and a reduction motor is provided on the back of the machine body 100. The reduction motor is fixed at the position on the right back of the conveyor. The working end of the reduction motor is fixedly connected to the rotating shaft 102 on the right side, and the main belt 101 is sleeved between the two rotating shafts 102.

[0041] In this embodiment, two support frames are fixedly installed at the bottom of the body 100.

[0042] Working principle and usage process of this utility model:

[0043] When this utility model is in use, the geared motor is turned on to drive the main belt 101 and the auxiliary belt 200 to rotate. At this time, the second valve 214 on the three-way pipe 202 is closed and the first valve 213 is opened. Then, the external negative pressure pump generates negative pressure, which causes negative pressure to be generated inside the long box 208. When the negative pressure port 207 on the rotating auxiliary belt 200 is above the U-shaped sealing gasket 212, negative pressure is generated inside the negative pressure port 207. When the negative pressure port 207 in the moving auxiliary belt 200 moves away from the U-shaped sealing gasket 212, the negative pressure disappears.

[0044] Then, the medicine bottle containing the medicine is placed on the negative pressure port 207 on the left side of the rotating auxiliary belt 200, and the bottom of the medicine bottle contacts the top of the telescopic ring 211 in the negative pressure port 207. At this time, the top of the telescopic ring 211 contacts the medicine bottle containing the medicine and compresses it downward. After compression to a certain position, the compression stops. At this time, the negative pressure port 207 generates negative pressure on the bottom of the medicine bottle to limit it. Then, the two main belts 101 and the auxiliary belt 200 drive the medicine bottle to move and complete the bagging operation. During the movement and conveying process, the negative pressure generated by the bottom negative pressure port 207 limits the medicine bottle to avoid the possibility of rotation, displacement or friction and wear on the outer wall during the movement. After the bagging and sealing are completed, the medicine bottle is moved to the right side of the conveyor. At this time, the negative pressure port 207 is above the U-shaped sealing pad 212. At this time, the negative pressure at the bottom of the medicine bottle disappears, and the medicine bottle can be removed.

[0045] During the conveying and limiting process of the medicine bottle, negative pressure wind is generated in the three-way pipe 202, causing the fan blade 305 to rotate, which in turn drives the rotating rod 302 to rotate. The rotating rod 302 drives the two sets of vertical brushes 306 to rotate and clean the dust and impurities intercepted on the surface of the filter screen 303 (when under negative pressure, dust or impurities are attached to the back of the filter screen 303). Then the dust or impurities fall to the bottom of the inner wall of the dust collection box 300, which can filter the dust or impurities.

[0046] When dust accumulates inside the negative pressure port 207, connecting pipe 210, and outer pipe 201 after prolonged use, first open the top plate 301 of the dust collection box 300, remove the dust and impurities accumulated inside the dust collection box 300, then replace the top plate 301 and secure it with bolts. At this point, close the first valve 213 and open the second valve 214. Then, blow high-pressure air into the three-way pipe 202 using a blower. The high-pressure air passes sequentially through the outer pipe 201, connecting pipe 210, long box 208, and is blown out through the negative pressure port 207 above. This effectively removes the dust accumulated and adhering to the inner walls of the outer pipe 201, connecting pipe 210, long box 208, and negative pressure port 207. Impurities are blown out for cleaning. After cleaning, the top plate 301 is opened again to remove the dust and impurities accumulated in the dust collection box 300. The top plate 301 is then fixed to the dust collection box 300. The first valve 213 is then opened and the second valve 214 is closed, and the conveyor can start conveying medicine bottles. During this period, dust or impurities that are not in a negative pressure state adhere to the front of the filter screen 303. The dust adhering to the front of the filter screen 303 is cleaned by rotating the vertical brush 306. When the blower stops running, the top plate 301 is opened to clean the dust and impurities in the dust collection box 300 outward. After cleaning, the top plate 301 is fixed to the dust collection box 300.

[0047] 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.
