Description

Technical Field

[0001] This utility model relates to the field of chemical packing technology, and in particular to an automatic packing mechanism for packing materials. Background Technology

[0002] In industries such as petroleum, chemical, and environmental protection, packed towers are a key mass transfer device. They are filled with a large amount of packing material, which needs to be accurately measured and packaged before leaving the factory to facilitate transportation, storage, and subsequent filling operations.

[0003] Existing automated packing mechanisms for fillers rely primarily on two core processes when performing packaging tasks: first, supplying packaging materials (such as large woven bags, ton bags, or specific linings) to contain the fillers; and second, precisely clamping and fixing the bag openings or containers as workpieces so that subsequent automated weighing, filling, and sealing can be carried out.

[0004] In current production practices, the rolls used to supply packaging materials (especially films or moisture-proof layers for bag linings) are typically large and heavy. When a roll runs out and needs to be replaced, operators often have to manually loosen the locking device, laboriously remove the old roll core, and then hoist the new, heavy roll into place and relock it. This process is not only time-consuming and labor-intensive, heavily reliant on manual labor, but also significantly extends production line downtime.

[0005] Meanwhile, at the filling station, there are also bottlenecks in clamping and securing packaging bags or containers. Many devices use manual clamps or simple pneumatic grippers. At the beginning of each packaging cycle, the bag opening needs to be manually fitted onto the clamp and locked; after filling, it needs to be manually released and removed. This method has low automation and uneven clamping force, which is not only an efficiency bottleneck in the entire automated packaging process, but also difficult to adapt to the need for rapid switching between different bag opening sizes, and cannot meet the requirements of high-throughput, continuous production.

[0006] Existing packing tower packing mechanisms have significant shortcomings in terms of ease of replacement and adjustment of packaging material rolls and automatic clamping and unloading of packaged workpieces. The cumbersome operation and low degree of automation in these two aspects contribute to overall low packaging efficiency, making it difficult to meet the demands of modern chemical production for efficient, continuous, and automated packaging.

[0007] Therefore, this utility model proposes an automatic packaging mechanism for fillers to overcome the shortcomings of the prior art. Utility Model Content

[0008] To overcome the above shortcomings, this utility model provides an automatic packaging mechanism for fillers, which aims to improve the problems of cumbersome and labor-intensive replacement of packaging material rolls, long downtime, low degree of automation and low efficiency in clamping and fixing of packaged workpieces in the existing automatic packaging mechanism.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: an automatic packing mechanism for fillers, comprising an adjusting component and a clamping component. The adjusting component includes a hollow plate, a motor screw structure, a first sliding block, a connecting shaft, and a bolt. The first sliding block is slidably fitted inside the hollow plate. The motor screw structure is fixed to the top of the hollow plate and is drively connected to the first sliding block. The connecting shaft is detachably installed on the first sliding block, and the bolt is threadedly connected to the first sliding block and can radially abut against the connecting shaft. The adjustment assembly also includes a support plate; the support plate is fixedly connected to the bottom of the hollow plate, and the lower end of the connecting shaft is inserted into the support plate.

[0010] Preferably, the clamping assembly includes a hydraulic cylinder, a rotating disk, a connecting block, a slotted plate, a second sliding block, a limiting post, and a clamping plate. The slotted plate is rotatably connected to the top of the rotating disk, the second sliding block is radially slidably connected to the rotating disk, the clamping plate is fixed to the second sliding block, the slotted plate has grooves corresponding to the second sliding block, the limiting post connects to the second sliding block and slides within the grooves, the hydraulic cylinder is fixed to the rotating disk, and the output end of the hydraulic cylinder is connected to the slotted plate via the connecting block.

[0011] Preferably, the clamping assembly further includes a connecting plate, through which the hydraulic cylinder is fixed to the side wall of the rotating disk.

[0012] Preferably, the clamping assembly further includes a bolt, through which the output end of the hydraulic cylinder is connected to the connecting block.

[0013] Preferably, the connecting block is hinged to the edge of the hollow slot plate.

[0014] Preferably, the clamping assembly further includes a slide plate, which is fixed to the rotating disk, and the second sliding block is slidably connected to the side wall of the slide plate.

[0015] Preferably, the limiting post is fixed to the outer wall of the second sliding block.

[0016] Preferably, the grooves formed on the hollow slot plate are spiral guide grooves.

[0017] This utility model has the following beneficial effects: 1.

[0018] 2. This utility model solves the problems of low automation, complex structure and poor adaptability of workpiece clamping in the prior art by setting a hydraulic cylinder drive connecting block, which is hinged to the edge of the empty slot plate. The rotation of the empty slot plate drives the spiral guide groove on it, which pushes the limiting post connected to the second sliding block.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-5 This utility model provides an automatic packaging mechanism for fillers, which aims to solve the problems of cumbersome replacement of packaging materials and inconvenient workpiece clamping and positioning in the prior art.

[0023] Specifically, it includes an adjustment component 1 and a clamping component 2. The adjustment component 1 is used to adjust the installation height of the packaging film roll and to enable quick replacement, while the clamping component 2 is used to rotate and clamp the workpiece.

[0024] Adjustment assembly 1 includes a hollow plate 101, a motor screw structure 102, a first sliding block 103, a connecting shaft 104, and bolts 106. The first sliding block 103 is slidably fitted inside the hollow plate 101. The motor screw structure 102 is fixed to the top of the hollow plate 101 and is drively connected to the first sliding block 103. The motor screw structure 102 drives the first sliding block 103 to move up and down along the vertical direction of the hollow plate 101. The connecting shaft 104 is detachably mounted on the first sliding block 103. 3. The connecting shaft 104 is used to install the membrane roll. The bolt 106 is threadedly connected to the first sliding block 103 and can radially abut against the connecting shaft 104. By tightening the bolt 106, the connecting shaft 104 can be quickly locked in the first sliding block 103. The adjusting assembly 1 also includes a support plate 105. The support plate 105 is fixedly connected to the bottom of the hollow plate 101. The lower end of the connecting shaft 104 is inserted into the support plate 105. The support plate 105 provides support for the lower end of the connecting shaft 104 to ensure the stability of the installation of the connecting shaft 104.

[0025] The clamping assembly 2 includes a hydraulic cylinder 201, a rotating disk 202, a connecting block 204, a slotted plate 206, a second sliding block 207, a limiting post 208, and a clamping plate 210. The rotating disk 202 can be driven to rotate by a power device (not shown). The slotted plate 206 is rotatably connected to the top of the rotating disk 202. The second sliding block 207 is radially slidably connected to the rotating disk 202. Preferably, multiple second sliding blocks 207 are evenly distributed along the circumference of the rotating disk 202, and the clamping plate 210 is fixed to the corresponding second sliding block 207. For directly clamping workpieces, the slotted plate 206 has grooves corresponding to the second sliding block 207. The limiting post 208 is connected to the second sliding block 207 and slides in the groove. The hydraulic cylinder 201 is fixed to the rotating disk 202. The output end of the hydraulic cylinder 201 is connected to the slotted plate 206 through the connecting block 204. When the hydraulic cylinder 201 is activated, it pushes the slotted plate 206 to rotate through the connecting block 204. The groove on the slotted plate 206 pushes the limiting post 208, causing the second sliding block 207 to perform radial clamping or loosening actions.

[0026] The clamping assembly 2 also includes a connecting plate 203. One end of the connecting plate 203 is fixedly connected to the side wall of the housing of the hydraulic cylinder 201, and the other end of the connecting plate 203 is fixedly connected to the side wall of the rotating disk 202. The connecting plate 203 provides a stable mounting base for the hydraulic cylinder 201 on the rotating disk 202, preventing the hydraulic cylinder 201 from loosening when it rotates with the rotating disk 202.

[0027] The clamping assembly 2 also includes a bolt 205, which is used to achieve a reliable connection between the output end of the hydraulic cylinder 201 and the connecting block 204. For example, the output end of the hydraulic cylinder 201 can be a piston rod with a threaded hole at the end. The bolt 205 passes through the through hole on the connecting block 204 and is screwed into the threaded hole of the piston rod, thereby securely connecting the connecting block 204 to the output end of the hydraulic cylinder 201 and ensuring that the linear motion of the hydraulic cylinder 201 can be accurately transmitted to the connecting block 204.

[0028] To achieve smooth transmission, the connecting block 204 is hinged to the edge of the empty slot plate 206. Specifically, the connecting block 204 may have a fork-shaped joint, and the edge of the empty slot plate 206 is provided with a corresponding ear plate. A pin passes through the fork-shaped joint and the ear plate to achieve a rotatable connection. When the connecting block 204 moves linearly under the drive of the hydraulic cylinder 201, it can smoothly push the empty slot plate 206 to rotate around the central axis of the rotating disk 202, converting the translation of the hydraulic cylinder 201 into the rotation of the slot plate 206.

[0029] To provide more precise guidance, the clamping assembly 2 also includes a slide plate 209, which is fixed to the rotating disk 202 and extends radially along the rotating disk 202. The side wall of the slide plate 209 forms a guide rail, and the corresponding side wall of the second sliding block 207 is provided with a groove that cooperates with the guide rail. The second sliding block 207 is slidably connected to the side wall of the slide plate 209 through this groove. The slide plate 209 ensures that the second sliding block 207 can only reciprocate radially, which improves the stability and accuracy of the clamping action.

[0030] To achieve motion conversion, the limiting post 208 is fixed to the outer wall of the second sliding block 207. For example, the limiting post 208 is set perpendicular to the sliding direction of the second sliding block 207 and protrudes upward. The upper end of the limiting post 208 extends into the groove of the empty slot plate 206. When the empty slot plate 206 rotates, the side wall of the groove pushes the limiting post 208. Since the limiting post 208 is fixed on the second sliding block 207 and the second sliding block 207 can only slide radially, the limiting post 208 converts the rotational motion of the empty slot plate 206 into the radial linear motion of the second sliding block 207.

[0031] To achieve a specific motion trajectory, the groove on the slotted plate 206 is a spiral guide groove. When the slotted plate 206 rotates around its center at a fixed angle, the groove wall of the spiral guide groove will push the limiting post 208 to move a radial distance on the rotating disk 202. By designing the pitch and shape of the spiral guide groove, the functional relationship between the radial displacement of the second sliding block 207 and the rotation angle of the slotted plate 206 can be precisely controlled, thereby achieving precise clamping and synchronous control of workpieces of different sizes.

[0032] Working principle: When using the automatic packaging mechanism for fillers, firstly, the adjusting component 1 is used to adjust the position and height of the connecting shaft 104. At the same time, the adjusting component 1 can quickly change the film roll, while the clamping component 2 is used to rotate and clamp the workpiece. Next, when adjusting component 1, the motor screw structure 102 first drives the first sliding block 103 to move. Then, the first sliding block 103 rotates inside the hollow plate 101. At the same time, the movement of the first sliding block 103 will drive the connecting shaft 104 to move. When installing the connecting shaft 104, the bottom of the connecting shaft 104 needs to be slid into the inside of the first sliding block 103 first. Then, pull the connecting shaft 104 so that its top is in contact with the top of the first sliding block 103. Next, align the position of the connecting shaft 104 with the top of the support plate 105, insert the connecting shaft 104 into the inside of the support plate 105, and then rotate 106. After 106 is tightened, the diameter of the hole opened inside the first sliding block 103 is reduced. Then, the position of the connecting shaft 104 can be clamped, which greatly reduces the replacement speed of the connecting shaft 104. Next, when clamping the workpiece, the rotating disk 202 first rotates the workpiece, and then the output end of the hydraulic cylinder 201 drives the bolt 205 to move. The side wall of the hydraulic cylinder 201 is provided with a connecting plate 203, and the side wall of the connecting plate 203 is fixed to the side wall of the rotating disk 202. Then, during the movement of the bolt 205, the connecting block 204 is moved. Then, the connecting block 204 is subjected to force and drives the empty slot plate 206 to rotate together. At the same time, the bottom of the empty slot plate 206 rotates to the top of the rotating disk 202. During the rotation of the empty slot plate 206, since there is a groove inside, the limiting post 208 can be moved along the inside of the groove. After the limiting post 208 moves, the second sliding block 207 on the outer wall moves. During the movement of the second sliding block 207, the clamping plate 210 on the side wall moves. Then, the side wall of the second sliding block 207 slides on the side wall of the sliding plate 209, achieving the effect of clamping the workpiece.
