Description

Technical Field

[0001] This utility model relates to the field of packaging equipment, specifically to a novel mechanism for a bag-repairing machine. Background Technology

[0002] Traditional bag replenishment mechanisms employ a single-rail supported replenishment trough structure. Due to limitations in the timing belt arrangement, the trough can only be supported on one side, and cannot be simultaneously fixed by two guide rail sliders. This structure is prone to uneven stress during long-term operation, especially in 12-column stations with long troughs, where single-sided support struggles to maintain balance, causing the trough to gradually tilt. Tilting can lead to collisions between adjacent troughs, triggering overload alarms. Furthermore, tilting can cause misalignment between the replenishment trough and the turntable trough, ultimately resulting in replenishment failure.

[0003] To address the aforementioned issues, we have made a series of improvements. Utility Model Content

[0004] The purpose of this utility model is to provide a novel mechanism for a bag-repairing machine, so as to overcome the above-mentioned shortcomings and deficiencies of the existing technology.

[0005] A novel mechanism for a bag-repairing machine includes: a bag-repairing material trough conveying mechanism, a bag-repairing scraping assembly, a feeding guide trough, a detection photoelectric sensor, a turntable assembly, and a discharge guide trough. The bag-repairing material trough conveying mechanism is connected to the turntable assembly at the 9 o'clock position. One end of the bag-repairing scraping assembly is connected to the bag-repairing material trough conveying mechanism, and the other end of the bag-repairing scraping assembly is connected to the turntable assembly. The feeding guide trough is connected to the turntable assembly at the 12 o'clock position. The detection photoelectric sensor is located at the connection between the feeding guide trough and the turntable assembly. The discharge guide trough is connected to the turntable assembly at the 3 o'clock position.

[0006] The bag-filling material conveying mechanism includes: a servo motor, a reducer, a driving synchronous pulley, a tensioning pulley mounting plate, a synchronous belt tensioning pulley, a fixed plate, a first driven synchronous pulley, a second driven synchronous pulley, a guide rail mounting plate, a guide rail, a material trough, a clearance connection structure, a synchronous belt connection structure, and a synchronous belt. The servo motor is connected to the reducer, and the reducer is connected to the driving synchronous pulley. The driving synchronous pulley is located at the bottom end of the tensioning pulley mounting plate. The synchronous belt tensioning pulleys are symmetrically arranged on both sides of the top end of the tensioning pulley mounting plate. The top end of the tensioning pulley mounting plate is connected to the guide rail mounting plate through a fixed plate. The first and second driven synchronous pulleys are located at the front and rear ends of the guide rail mounting plate. The guide rail is located on the guide rail mounting plate. The material trough is connected to the guide rail through a clearance connection structure and a synchronous belt connection structure. The synchronous belt is connected to the driving synchronous pulley, the synchronous belt tensioning pulley, the first driven synchronous pulley, the second driven synchronous pulley, the guide rail, and the synchronous belt connection structure.

[0007] Furthermore, the synchronous belt connection structure is arranged in a stepped manner from the upper right to the lower left on the guide rail. The avoidance connection structure is mirror-symmetrically arranged on both sides of the straight line formed by the synchronous belt connection structures. The avoidance connection structure includes: an avoidance support base, an avoidance slider, and an avoidance metal part. The top end of the avoidance support base is connected to the material trough, and the bottom end of the avoidance support base is connected to the avoidance slider through the avoidance metal part. The width of the middle hole of the avoidance metal part is greater than the width of the synchronous belt. The avoidance slider is connected to the guide rail. The synchronous belt connection structure includes: a synchronous support base, a synchronous slider, and a synchronous metal part. The top end of the synchronous support base is connected to the material trough, and the bottom end of the synchronous support base is connected to the synchronous slider through the synchronous metal part. The synchronous metal part has a synchronous middle hole, and the inner wall shape of the synchronous middle hole matches the tooth shape of the contoured synchronous belt. The synchronous slider is connected to the guide rail.

[0008] The beneficial effects of this utility model are:

[0022] Example 1

[0023] like Figure 1-4 As shown, a novel mechanism for a bag-repairing machine includes: a bag-repairing material trough conveying mechanism 100, a bag-repairing scraping assembly 200, a feeding guide trough 300, a detection photoelectric sensor 400, a turntable assembly 500, and a discharge guide trough 600. The bag-repairing material trough conveying mechanism 100 is connected to the turntable assembly 500 at the 9 o'clock position. One end of the bag-repairing scraping assembly 200 is connected to the bag-repairing material trough conveying mechanism 100, and the other end of the bag-repairing scraping assembly 200 is connected to the turntable assembly 500. The feeding guide trough 300 is connected to the turntable assembly 500 at the 12 o'clock position. The detection photoelectric sensor 400 is located at the connection between the feeding guide trough 300 and the turntable assembly 500. The discharge guide trough 600 is connected to the turntable assembly 500 at the 3 o'clock position.

[0024] The bag-filling material conveying mechanism 100 includes: a servo motor 110, a reducer 120, a driving synchronous pulley 130, a tensioning pulley mounting plate 140, a synchronous belt tensioning pulley 150, a fixed plate 160, a first driven synchronous pulley 170, a second driven synchronous pulley 180, a guide rail mounting plate 190, a guide rail 1100, a material trough 1110, a clearance connection structure 1120, a synchronous belt connection structure 1130, and a synchronous belt 1140. The servo motor 110 is connected to the reducer 120, and the reducer 120 is connected to the driving synchronous pulley 130. The driving synchronous pulley 130 is located at the bottom end of the tensioning pulley mounting plate 140, and the synchronous belt tensioning pulleys 150 are symmetrical. The tensioning wheel mounting plate 140 is located on both sides of its top end. The top end of the tensioning wheel mounting plate 140 is connected to the guide rail mounting plate 190 via a fixing plate 160. The first driven synchronous wheel 170 and the second driven synchronous wheel 180 are located at the front and rear ends of the guide rail mounting plate 190. The guide rail 1100 is located on the guide rail mounting plate 190. The material trough 1110 is connected to the guide rail 1100 via an avoidance connection structure 1120 and a synchronous belt connection structure 1130. The synchronous belt 1140 is connected to the driving synchronous wheel 130, the synchronous belt tensioning wheel 150, the first driven synchronous wheel 170, the second driven synchronous wheel 180, the guide rail 1100, and the synchronous belt connection structure 1130.

[0025] The timing belt connection structures 1130 are arranged in a stepped manner from the upper right to the lower left on the guide rail 1100. The clearance connection structures 1120 are mirror-symmetrically located on both sides of the straight line formed by the timing belt connection structures 1130. Each clearance connection structure 1120 includes a clearance support 1121, a clearance slider 1122, and a clearance metal part 1123. The top of the clearance support 1121 is connected to the material trough 1110, and the bottom of the clearance support 1121 is connected to the clearance slider 1122 via the clearance metal part 1123. The width of the central hole in the clearance metal part 1123 is greater than that of the timing belt 114. The width is 0, and the slider 1122 is connected to the guide rail 1100. The synchronous belt connection structure 1130 includes: synchronous support 1131, synchronous slider 1132 and synchronous metal part 1133. The top end of the synchronous support 1131 is connected to the material trough 1110, and the bottom end of the synchronous support 1131 is connected to the synchronous slider 1132 through the synchronous metal part 1133. The synchronous metal part 1133 is provided with a synchronous intermediate hole 1134. The inner wall shape of the synchronous intermediate hole 1134 matches the tooth shape of the contoured synchronous belt 1140. The synchronous slider 1132 is connected to the guide rail 1100.

[0026] The operating principle of this utility model is as follows: When multiple rows of bags pass through the feed guide chute 300 and turn onto the turntable assembly 500, they pass through the photoelectric sensor 400 to detect whether there are missing bags in the corresponding guide chute. The missing bag information is transmitted to the control system. If there are missing bags, the control system provides corresponding information, and the bag replenishment conveying mechanism 100 drives the chute 1110 located at the storage position 1 to the missing bag position. The bag replenishment scraper assembly 200 replenishes the bag at the corresponding position. The bag replenishment scraper assembly 200 is an existing structure, so its internal parts and specific principles will not be described in detail. After bag replenishment is completed, the chute 1110 returns to the empty bag position 2. After bag replenishment is completed, the turntable assembly 500 rotates to the next station until it is aligned with the discharge guide chute 600, and then the bag is conveyed to the downstream equipment by the discharge scraper. The turntable assembly 500 is an existing structure, so its internal parts and specific principles will not be described in detail.

[0027] Bag replenishment principle: When the machine is started for the first time, the material trough 1110 is completely empty. When the feeding guide trough 300 detects no missing bags, the bag replenishment machine does not operate. When the feeding guide trough (300) detects that the number of missing bags is ≥1 bag, all the remaining bags are replenished into the material trough 1110. Starting from the first material trough, the remaining bags in the front missing bag station are replenished into the material trough 1110 in sequence.

[0028] When there are packs to be replenished in the feed trough 1110, if the front-end station detects a missing pack, it compares the number of missing packs with the number in the feed trough 1110. If the number of missing packs at the front-end station is greater than the number of packs in the feed trough 1110, then all the remaining packs at the front-end station are replenished into the feed trough 1110. If the number of missing packs is less than or equal to the number of packs in the feed trough 1110, then the corresponding number of missing packs are replenished from the feed trough 1110.

[0029] Bag replenishment operation: The servo motor 110 is driven to the active synchronous pulley 130 through the reducer 120. The active synchronous pulley 130 drives the synchronous belt 1140, which is then transmitted sequentially through the synchronous belt tension pulley 150, the first driven synchronous pulley 170, and the second driven synchronous pulley 180. It has its own tensioning system.

[0030] Therefore, this utility model uses the synchronous belt 1140 as the power carrier for the bag replenishment trough conveying mechanism 100. The innovation of this utility model lies in the fact that traditional synchronous belt structures drive the trough to move on the guide rails via a slider guide rail structure. As mentioned in the background art, this process involves single-rail movement, which is very unstable. This utility model, however, has two connection structures: a clearance connection structure 1120 and a synchronous belt connection structure 1130. Each independent trough 1110 has both a clearance connection structure 1120 and a synchronous belt connection structure 1130, ensuring double guide rail support during operation. The width of the hole in the clearance metal part 1123 is greater than that of the synchronous belt 1140, so it does not actually contact the synchronous belt 1140. In this process, the clearance connection structure 1120 only serves to fix, support, and guide the trough. The hole in the middle of the synchronous belt connecting structure 1130 is a contoured synchronous belt 1140 that matches the tooth shape of the synchronous belt, allowing it to be pressed tightly. Therefore, the synchronous belt 1140 and the synchronous metal part 1133 are actually connected. Thus, the synchronous belt connecting structure 1130 and the synchronous belt 1140 work together to provide both driving and support guidance. Together, they form a stable double-rail structure.

[0031] like Figure 3 and Figure 4As shown, to achieve this structure, there are requirements for the installation positions of the avoidance connection structure 1120 and the synchronous belt connection structure 1130. First, regarding their position, to ensure stability, there needs to be a certain distance between the avoidance connection structure 1120 and the synchronous belt connection structure 1130. In this invention, this distance is approximately half the length of the material trough 1110. Therefore, the synchronous belt connection structures 1130 located at the top of their own material trough 1110 are arranged sequentially, given their thickness. After 11 groups are arranged, the last synchronous belt connection structure 1130 is located at the end of its own material trough 1110, forming a stepped arrangement structure. Due to the positional distance between the synchronous belt connection structure 1130 and the avoidance connection structure 1120 mentioned above, the avoidance connection structure 1120, located on the same material trough 1110, naturally has a corresponding position. Since the synchronous belt connection structure 1130 has thickness, the avoidance connection structure 1120 corresponding to the upper part of the synchronous belt connection structure 1130 is located in the lower part of the material trough 1110, and the avoidance connection structure 1120 corresponding to the lower part of the synchronous belt connection structure 1130 is located in the upper part of the material trough 1110. In other words, if the entire synchronous belt connection structure 1130 is considered as the diagonal of a matrix, then the avoidance connection structure 1120 is divided into two straight lines, mirror-symmetrically positioned on both sides of the synchronous belt connection structure 1130. This design allows each material trough to move smoothly via dual guide rails, while each moves independently without affecting the others. Compared to other mechanisms, this design is more compact, smaller in size, and operates more smoothly.

[0032] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
