Description

Technical Field

[0001] The invention relates to the technical field of filling, and in particular to an automatic bag filling mechanism based on woven bags and a control method thereof. Background Art

[0002] The filling of flexible objects such as triangular belts is different from the filling industry of ordinary feed. Due to the certain flexibility of triangular belts and the large number of product models (different lengths, widths, etc.), the state of filling is uncertain. At the same time, in order to improve the utilization rate of woven bags, the industry generally needs to put more than 10 bundles of triangular belts in each bag, and the loading volume is large. There are several main methods of bag filling on the market:

[0003] 1. The operator opens the mouth of the woven bag manually, and uses the other hand or another person to insert the V-belt into the woven bag;

[0004] 2. Use bag filling equipment to put the bundled triangular belts into a cylindrical storage barrel. The front end of the storage barrel is open for putting on woven bags, the rear end is equipped with a push plate controlled by a cylinder, and the upper part is equipped with a loading port. When a certain number of triangular belts are loaded, it is necessary to manually stuff the triangular belts into the gap of the storage barrel, fill the storage barrel with a certain number of triangular belts, put the mouth of the woven bag on the mouth of the storage barrel, and then stuff the triangular belt in the storage barrel into the gap of the storage barrel again, ensuring that the highest surface of the triangular belt is lower than the highest surface of the mouth of the woven bag. Then the cylinder pushes the triangular belt in the storage barrel and pours it into the woven bag.

[0005] The following defects exist in the manual bag filling method: the triangular belt is irregular, and has many sizes and specifications. The triangular belt has a relatively large relative friction when filling the bag, and manual bag filling is very difficult. The following defects exist in the existing bag filling equipment: due to the specification restrictions of the woven bag, the diameter of the storage barrel is small, and the opening of the upper discharge gap is also relatively small. When placing the triangular belt, it is easy for products to pile up and exceed the highest surface of the cylindrical storage barrel; when manually putting the woven bag on the barrel mouth of the storage barrel, it is necessary to force the raised triangular belt into the gap of the storage barrel, and hold the mouth of the woven bag with one hand, and manually assist to make the bag mouth open more. The labor intensity is relatively high, and the filling is difficult and the efficiency is low.

[0006] Based on this, this case is brought forward. Summary of the invention

[0007] The object of the present invention is to provide an automatic bag filling mechanism based on woven bags and a control method thereof, so as to improve the degree of automation of bag filling of flexible articles such as V-belts and improve production efficiency.

[0008] In order to achieve the above object, the technical solution of the present invention is as follows:

[0009] The invention discloses an automatic bag filling mechanism based on woven bags, comprising a frame and a push plate, wherein the frame is provided with a movable barrel wall, a fixed barrel wall, a baffle plate and drive components one and two, wherein the drive component one is used to control the approach and separation of the movable barrel wall and the fixed barrel wall, wherein the movable barrel wall and the fixed barrel wall form a material storage barrel, wherein both ends of the material storage barrel in the length direction are open, and an upper end in the height direction forms a material feed port, wherein the drive component two is used to control the movement of the push plate in the length direction inside the material storage barrel, and the baffle plate is located below the material storage barrel and is used to block the gap between the movable barrel wall and the fixed barrel wall.

[0010] Furthermore, the driving component 2 is arranged below the storage barrel, and a connecting rod is fixed between the driving end of the driving component 2 and the push plate, and the connecting rod passes through the gap between the movable barrel wall and the fixed barrel wall; a driving component 3 is provided on the frame, and the driving component 3 is used to control the baffle plate to approach or move away from the gap between the movable barrel wall and the fixed barrel wall. When the baffle plate moves away from the gap between the movable barrel wall and the fixed barrel wall, the connecting rod can move in the length direction of the gap.

[0011] Furthermore, support wheels for supporting the baffle are fixed on the frame.

[0012] Furthermore, one end of the movable barrel wall and the fixed barrel wall in the length direction are both configured with upper and lower pouring spouts.

[0013] Furthermore, a driving component four and a pressure cover are provided on the frame, and the driving component four is used to control the pressure cover to block or keep away from the feed inlet of the storage barrel.

[0014] Furthermore, the driving component four is a cylinder, the gland and the cylinder body of the cylinder are hinged on the frame, and the telescopic end of the cylinder is hinged to the gland.

[0015] Furthermore, the frame is provided with a limit screw for limiting the rotation of the driving component 4.

[0016] Furthermore, the movable barrel wall is slidably connected to the frame.

[0017] Furthermore, the baffle is slidably connected to the frame.

[0018] A control method for the automatic bag filling mechanism comprises the following steps:

[0019] S01: Driving component 2 drives the push plate to move to the end of the storage barrel away from the upper and lower pouring ports, and driving component 4 drives the pressure cover to open the loading port;

[0020] S02: Driving component 1 drives the movable barrel wall away from the fixed barrel wall;

[0021] S03: Driving component 3 drives the baffle to block the gap between the movable barrel wall and the fixed barrel wall;

[0022] S04: Put the bundled materials into the storage barrel from the loading port. Every time a bundle is placed, the driving component drives the movable barrel wall to make a reciprocating motion close to and away from the fixed barrel wall until the last bundle of materials is placed. After the placement is completed, the driving component drives the movable barrel wall close to the fixed barrel wall.

[0023] S05: After the above actions are completed, the drive component 4 drives the pressure cover to seal the feeding port;

[0024] S06: Put woven bags into the upper and lower pouring openings of the storage barrel;

[0025] S07: Driving assembly three drives the bottom baffle to move away from the gap between the movable barrel wall and the fixed barrel wall;

[0026] S08: Driving component 2 drives the push plate to move toward one end of the woven bag, pushing the material in the storage barrel into the woven bag;

[0027] S09: After pushing is completed, return to step S01 and repeat the work.

[0028] The advantages of the present invention are:

[0029] 1. The storage barrel of the prior art is a fixed integrated structure, which cannot expand the container volume. When loading, the V-belt will overflow the barrel and needs to be adjusted manually. The storage barrel of the present invention is a split structure. The fixed barrel wall and the movable barrel wall are used to cooperate with the baffle to expand the container volume, greatly reducing the loading failure caused by the flexibility and irregularity of the V-belt. In addition, the reciprocating motion of the movable barrel wall forms vibration compensation to eliminate the gap between the V-belt and the storage barrel;

[0030] 2. To further improve the success rate of bag filling, the pressure cover is pressed on the barrel during bag filling to form a closed surface with the fixed barrel device and the movable barrel device. The risk of overflow caused by excessive V-belts can be avoided, so that all the V-belts in the barrel can be filled into the woven bag. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The present invention is further described in detail below with reference to the embodiments.

[0040] This embodiment proposes an automatic bag filling mechanism based on woven bags, such as Figures 1 to 6 As shown, it includes a frame, a movable barrel wall 109, a fixed barrel wall 102, a baffle 108, a push plate 104, a pressure cover 103 and a plurality of driving components.

[0041] The movable barrel wall 109 and the fixed barrel wall 102 are symmetrically arranged on the frame, and the movable barrel wall 109 is slidably connected to the frame through a slide rail 112. The movable barrel wall 109 and the slide rail 112 are connected through a support 110, and the fixed barrel wall 102 is fixed to the frame through the support 110. A driving component 101 is fixed on the frame, and the driving component 101 is used to control the movable barrel wall 109 to approach and separate from the fixed barrel wall 102. The movable barrel wall 109 and the fixed barrel wall 102 are close to form a storage barrel. Since the movable barrel wall 109 and the fixed barrel wall 102 in this embodiment are both arc-shaped barrel walls smaller than a semicircle, the storage barrel composed of the movable barrel wall 109 and the fixed barrel wall 102 has openings at both ends in the length direction, and a feed port is formed at the upper end in the height direction. One open end of the storage barrel is used to insert a woven bag.

[0042] The frame is located below the storage barrel and fixed with a second drive assembly 105. The second drive assembly 105 is used to control the push plate 104 to move in the length direction of the storage barrel, and is used to push the material in the storage barrel into the woven bag. The second drive assembly 105 and the push plate 104 are connected by a connecting rod 113. In order to facilitate the connection between the second drive assembly 105 and the push plate 104, the closest distance between the movable barrel wall 109 and the fixed barrel wall 102 is set to a distance slightly larger than the width of the connecting rod 113 in this embodiment, and the distance will not cause the material (especially the V-belt) in the storage barrel to fall. The second drive assembly 105 of this embodiment adopts an electric module, and the second drive assembly 105 is set below the storage barrel, which can reduce the volume of the whole machine and make the structure of the bag filling mechanism more compact.

[0043] When the movable barrel wall 109 is separated from the fixed barrel wall 102, the distance between them increases, which may cause the material in the storage barrel to fall. To solve this problem, the present embodiment sets a baffle 108 under the storage barrel to block the gap between the movable barrel wall 109 and the fixed barrel wall 102. However, in order to avoid interference between the connecting rod 113 and the baffle 108 when the push plate 104 moves, the present embodiment sets a driving component 3 106 on the frame, and the driving component 3 106 is used to control the baffle 108 to move closer to or away from the gap between the movable barrel wall 109 and the fixed barrel wall 102. Figure 5 As shown, when the push plate 104 needs to move, the driving assembly 3 106 will drive the baffle 108 to move to the side away from the movable barrel wall 109, so as to make way. In addition, a support wheel 115 for supporting the baffle 108 is fixed on the frame, and the baffle 108 is slidably connected to the frame through a slide rail 112 to increase the stability of the baffle 108.

[0044] In order to facilitate the woven bag to be put into the storage barrel, Figure 4 As shown, in this embodiment, the movable barrel wall 109 and one end of the fixed barrel wall 102 are designed to be in the form of upper and lower pouring openings 114, which serve as guides when the woven bag is put on the barrel, making it easier for the woven bag to be completely put into the barrel opening.

[0045] In the prior art, when the push plate 104 pushes the material, some of the material may be pushed out of the feed port. To solve this defect, the present embodiment adds a pressure cover 103 and a drive component 4 107. The drive component 4 107 is used to control the pressure cover 103 to block or keep away from the feed port of the storage barrel. The drive component 4 107 of the present embodiment adopts a cylinder, and the drive components 1 101 and 3 106 of the present embodiment also adopt cylinders. Figure 1 As shown, the gland 103 and the cylinder body of the cylinder are hinged on the frame, and the telescopic end of the cylinder is hinged to the gland 103. When the drive assembly 107 is extended, the gland 103 blocks the feed inlet, and when the drive assembly 107 is retracted, the gland 103 opens the feed inlet. Since the drive assembly 107 will rotate continuously when it is running, in order to avoid excessive rotation, as shown in FIG. Figure 6 As shown, a limit screw 111 is provided on the frame to limit the rotation of the driving component 4 107.

[0046] The use process of the bag filling mechanism in this embodiment is as follows:

[0047] S01: The driving component 2 105 drives the push plate 104 to move to the end of the storage barrel away from the upper and lower pouring ports 114, and the driving component 4 107 drives the pressure cover 103 to open the loading port;

[0048] S02: The driving component 101 drives the movable barrel wall 109 to move away from the fixed barrel wall 102 and to open a certain distance from the fixed barrel wall 102, thereby expanding the feed opening;

[0049] S03: The driving component 3 106 drives the baffle 108 to block the gap between the movable barrel wall 109 and the fixed barrel wall 102. When the baffle 108 is extended, it is supported on the supporting wheel 115, which can reduce the deformation of the baffle 108. At this time, the initial position of the storage barrel has completed the action;

[0050] S04: Put the bundled materials into the storage barrel from the loading port. Each time a bundle is placed, the driving component 101 drives the movable barrel wall 109 to make a reciprocating motion close to and away from the fixed barrel wall 102 until the last bundle of materials is placed. The reciprocating motion of the movable barrel wall 109 can form vibration compensation to eliminate the gap between the V-belt and the storage barrel. After placement, the driving component 101 drives the movable barrel wall 109 close to the fixed barrel wall 102.

[0051] S05: After the above actions are completed, the drive assembly 107 drives the pressure cover 103 to block the feeding port;

[0052] S06: Put a woven bag into the upper and lower pouring openings 114 of the storage barrel;

[0053] S07: The driving component 3 106 drives the bottom baffle 108 to move away from the gap between the movable barrel wall 109 and the fixed barrel wall 102, so as to make way for the connecting rod 113;

[0054] S08: The second driving component 105 drives the push plate 104 to move toward one end of the woven bag, pushing the material in the storage barrel into the woven bag;

[0055] S09: After pushing is completed, return to step S01 and repeat the work.

[0056] The above embodiments are only used to explain the concept of the present invention, rather than to limit the protection of the rights of the present invention. Any non-substantial changes to the present invention using this concept shall fall within the protection scope of the present invention.
