Description

Technical Field

[0001] This invention relates to the field of granular cotton baling technology, and more specifically to a granular cotton baling machine. Background Technology

[0002] Granular cotton is a non-combustible fiber granule product made from high-quality slag as the core raw material. After being melted at high temperature, it is made into inorganic fibers by high-speed centrifugal equipment and aggregated into mineral wool. It is then processed by a granulator. It has excellent heat insulation, sound insulation and fireproof properties and is widely used in filling hollow gaps in buildings, making fireproof, heat-insulating and sound-absorbing coatings, roof insulation boards and various sound-absorbing board products. It is an indispensable functional material in the industrial and construction fields.

[0003] Due to the characteristics of its molding process, granular cotton is fluffy and granular with a large volume. Packaging it is a necessary step for storage and transportation. As a result, granular cotton baling machines have become the core supporting equipment after the production and processing of granular cotton. To adapt to the fluffy characteristics of granular cotton, existing baling machines mostly adopt large-capacity bins and single-pass high-thrust compression structures, resulting in a large overall size of the equipment and high requirements for the floor space of the production plant.

[0004] Because existing baling machines lack precise weighing and segmented compression linkage design, the weight error of a single bale can reach more than 15 kg. Moreover, they mostly adopt a single compression method in one direction and one time, resulting in poor control of material rebound. This leads to uneven density of the formed bales and easy secondary dispersion. The structural design of existing baling machines does not take into account the integrated needs of baling and packaging. Usually, manual binding of compressed materials is required. Manual binding of materials is inefficient and results in low density of the bound materials, leading to significant material loss during transportation. Summary of the Invention

[0005] In view of the problems existing in the prior art, the present invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a granular cotton baling machine.

[0011] In a preferred embodiment of the granular cotton baling machine of the present invention, the pushing module includes a pushing box that is perpendicularly distributed to the pre-compression box. A pushing head driven by a compaction cylinder is slidably connected in the pushing box. The pushing box is seamlessly connected to the discharge port of the pre-compression box.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] This invention discloses a granular cotton baling machine.

[0025] Example 1 Reference Figure 1-8This invention provides a granular cotton baling machine, comprising a frame 1, a weighing buffer mechanism for weighing and feeding granular cotton, and a pressurizing and discharging mechanism for extruding and feeding material. The frame 1 includes a main support frame 11, on which a first load-bearing platform 12 is fixedly mounted via structural components. A second load-bearing platform 13 is located on the main support frame 11 above the first load-bearing platform 12, and the first and second load-bearing platforms 12 are arranged vertically and independently. The weighing buffer mechanism consists of a buffer module 2 and a weighing module 3 connected in series, and the buffer module 2 and the weighing module 3 work together to achieve cyclic feeding and precise quantitative weighing of materials. The pressurizing and discharging mechanism consists of a pre-compression module 4, a baling module 5, and a discharging and bagging module 6 connected sequentially, used for... After the material is pre-compressed and formed in sections, it is packaged. The frame 1 serves as the basic support structure of the whole machine, undertaking the installation and fixation of all functional modules. The main support frame 11 is the core load-bearing component of the frame 1. It adopts a welding forming process and bolts to reinforce the steel structural components, ensuring sufficient load-bearing capacity to support the weight of each module. The first load-bearing platform 12 and the second load-bearing platform 13 adopt a layered independent design, and there is no direct rigid connection between the two. The core purpose is to prevent the weight of the buffer module 2 on the second load-bearing platform 13 from being transferred to the weighing module 3 on the first load-bearing platform 12, thereby eliminating weight interference. The weighing buffer mechanism and the pressurizing and bagging mechanism are both integrated on the frame 1. Through their coordinated linkage, a complete operation process of granular cotton from feeding, weighing to compression, bagging, and bagging is formed, realizing fully automated packaging operation without manual intervention in the feeding, weighing, and compression stages.

[0026] Buffer module 2 includes a buffer box 21 corresponding to the second load-bearing platform 13. The buffer box 21 contains a buffer box baffle 22 driven by a buffer baffle cylinder 23. Weighing module 3 includes a weighing box 31 connected to the buffer box 21. The outlet of the buffer box 21 is aligned with the inlet of the weighing box 31. The buffer box baffle 22 is located between the outlet of the buffer box 21 and the inlet of the weighing box 31. The bottom of the weighing box 31 is also equipped with a weighing sensor 32 for weighing the material inside the weighing box 31. The weighing sensor 32 is located at the contact point between the weighing box 31 and the first load-bearing platform 12. The buffer box 21 is used to temporarily store granular cotton material to be weighed, so as to achieve stable material feeding. The buffer box baffle 22 is driven by the buffer baffle cylinder 23. It can be controlled by opening and closing, thereby controlling the discharge rhythm of the buffer box 21 and ensuring that all the material in the buffer box 21 can fall into the weighing box 31. The weighing sensor 32 and the first load-bearing platform 12 are installed in a non-rigid and non-contact manner, which can directly detect the total weight of the weighing box 31 and the material inside. By collecting weight data in real time, accurate quantitative weighing of the material can be achieved, providing an accurate material quantity basis for subsequent segmented pre-compression operations.

[0027] A ramp guide plate 35 is provided at the discharge port of the weighing box 31. A weighing box baffle 33, driven by a weighing baffle cylinder 34, is also installed on the weighing box 31. The weighing box baffle 33 is located between the discharge port of the weighing box 31 and the ramp guide plate 35. Both the buffer baffle cylinder 23 and the weighing baffle cylinder 34 are electrically connected to the weighing sensor 32. The ramp guide plate 35 is designed to be inclined, which can guide the material in the weighing box 31 to slide smoothly into the subsequent pre-compression module 4. The weighing box baffle 33 is driven by the weighing baffle cylinder 34, and its opening and closing state is the same as that of the buffer baffle. Plate 22 works in coordination, both controlled by electrical signals emitted by weighing sensor 32. When weighing sensor 32 detects that the material in weighing box 31 has reached the set weight, it will simultaneously send electrical signals to buffer baffle cylinder 23 and weighing baffle cylinder 34 to control buffer baffle 22 to close and weighing baffle 33 to open, realizing quantitative unloading. After weighing box 31 has finished unloading, weighing sensor 32 sends a reset signal to control buffer baffle 22 to open and weighing baffle 33 to close, entering the next round of feeding and weighing cycle, realizing automated linkage between weighing and feeding.

[0028] The pre-compression module 4 includes a pre-compression box 41 fixedly installed on the first load-bearing platform 12 and distributed parallel to the weighing box 31. The feed inlet of the pre-compression box 41 is connected to the weighing box 31 through a ramp guide plate 35. The pre-compression box 41 is also equipped with a continuous pre-compression device 42 for segmented pre-compression. The continuous pre-compression device 42 consists of a pre-compression head 422 slidably connected in the pre-compression box 41 and a pre-compression hydraulic cylinder 421 for driving the pre-compression head 422. The pre-compression hydraulic cylinder 421 is fixedly installed at the top of the pre-compression box 41 and is arranged to avoid the second load-bearing platform 13. The inner wall of the pre-compression box 41 is also equipped with a position for monitoring the position of the pre-compression hydraulic cylinder 421. Sensor 43 and pre-compression chamber 41 ensure that the material can smoothly enter the pre-compression chamber 41 through the inclined guide plate 35. The overall structure is relatively compact. The pre-compression chamber 41 serves as the working chamber for segmented pre-compression. Its size is adapted to the pre-compression requirements of granular cotton and can accommodate the material after multiple weighings. The continuous pre-compression device 42 can provide stable pre-pressure through the pre-compression hydraulic cylinder 421, driving the pre-compression head 422 to slide up and down in the pre-compression chamber 41 to perform vertical pre-compression on the material. The position sensor 43 is used to monitor the extension and retraction position of the pre-compression hydraulic cylinder 421 in real time and control the compression stroke of each pre-compression through the position sensor 43, gradually reducing the rebound amplitude of the material and achieving preliminary shaping.

[0029] The packing module 5 includes a packing box 51 perpendicularly distributed to the pre-compression chamber 41. A packing pusher head 53, driven by a compaction cylinder 52, is slidably connected within the packing box 51. The packing box 51 is seamlessly connected to the outlet of the pre-compression chamber 41. The packing pusher head 53 is connected to the piston end of the compaction cylinder 52, and its other end extends into the packing box 51. The packing pusher head 53 is L-shaped, consisting of a horizontal end and a vertical end. The horizontal section is adapted to the outlet of the pre-compression chamber 41, and the length of the horizontal section is adapted to the length of the packing box 51. (Pre-compression...) The pre-compressed material discharged from the outlet of the box 41 can all enter the pusher box 51. The horizontal end of the pusher head 53 is used to receive the pre-compressed material, and the vertical end is used to cooperate with the pusher head 53 to complete the horizontal final compression of the material. Its size design is adapted to the specifications of the formed bale block to ensure that the bale block is a standard cube after forming. The compaction cylinder 52 provides sufficient horizontal thrust to the pusher head 53. The pusher head 53 performs final compression on the pre-compressed material through horizontal extrusion to further increase the density of the bale block.

[0030] The push-bag module 5 also includes a shaping baffle cylinder 55 fixedly installed at the end of the push-bag box 51 away from the compaction cylinder 52. The piston rod of the shaping baffle cylinder 55 is connected to the push-bag shaping baffle 54. The push-bag shaping baffle 54 is set in the discharge end of the push-bag box 51 through the opening and closing of the shaping baffle cylinder 55. The opening and closing control of the push-bag shaping baffle 54 is realized by the extension and retraction movement of the shaping baffle cylinder 55. During the final pressing process, the push-bag shaping baffle 54 is in the closed state, cooperating with the push-bag push head 53 to form a closed extrusion space, ensuring that the material can be fully extruded and shaped, and ensuring that the bag shape is standardized and the density is uniform. After the final pressing is completed, the shaping baffle cylinder 55 drives the push-bag shaping baffle 54 to open, providing a channel for the subsequent bag blocks to be pushed to the bagging module 6.

[0031] The bagging module 6 includes a bagging box 61 perpendicularly distributed to the bag pushing box 51. The bagging box 61 is connected to the discharge end of the bag pushing box 51. The end of the bagging box 61 near the bag shaping baffle 54 is also provided with a bagging outlet 611 for bagging. A bagging pusher head 63 driven by a bagging pusher cylinder 62 is slidably connected in the bagging box 61. The bagging pusher cylinder 62 is electrically connected to the shaping baffle cylinder 55 to ensure that the formed bag blocks can smoothly enter the bagging box 61 for bagging and discharge. The size of the bag opening 611 is adapted to the specifications of the packaging bag, which facilitates the fitting and fixing of the packaging bag. The bag ejection pusher 63 is driven by the bag ejection pusher cylinder 62 and can slide smoothly in the bag ejection box 61, pushing the formed bag block from the bag ejection opening 611 into the pre-fitted packaging bag, realizing the integrated operation of packaging and bagging. The bag ejection pusher cylinder 62 is electrically linked with the shaping baffle cylinder 55. The bag ejection pusher cylinder 62 will only be activated when the bag shaping baffle 54 is fully opened.

[0032] The bagging module 6 includes a bagging box 61 and a position detection switch for detecting the position of the bag block. The position detection switch in the bagging box 61 is electrically connected to the bagging pusher cylinder 62. The position detection switch is installed inside the bagging box 61 and is used to detect the position of the formed bag block in the bagging box 61 in real time. When the bag block is pushed to the designated position of the bagging outlet 611, the position detection switch will send an electrical signal to the bagging pusher cylinder 62 to control the bagging pusher cylinder 62 to stop running, providing stable positioning for the operator to bag the bag.

[0033] The buffer baffle cylinder 23, weighing baffle cylinder 34, pre-compression hydraulic cylinder 421, compaction cylinder 52, shaping baffle cylinder 55, and unloading and pushing cylinder 62 are all linear drive components. They can be either hydraulic or electric drive components. The linear drive components are the power source for the operation of each module of the equipment. Their selection can be flexibly adjusted according to actual operation needs, site conditions, and cost budget. Hydraulic cylinders are commonly used in this field.

[0034] The frame 1 is equipped with maintenance ladders corresponding to the first load-bearing platform 12 and the second load-bearing platform 13. The maintenance ladders facilitate operators to climb to each load-bearing platform to perform daily inspections, maintenance and parameter adjustments on components such as the buffer module 2, weighing module 3 and pre-compression module 4 installed on the platform.

[0035] When using this device to compress and package granular cotton, the granular cotton material is continuously injected into the buffer box 21 of the buffer module 2 during operation. The weighing sensor 32 detects the weight of the material in the weighing box 31 in real time. When the material reaches the set weight (60kg), the buffer baffle cylinder 23 drives the buffer box baffle 22 to close, isolating subsequent feeding. At the same time, the weighing baffle cylinder 34 drives the weighing box baffle 33 to open, and the material slides smoothly into the subsequent segmented pre-compression structure through the inclined guide plate 35. After the weighing module 3 completes unloading, the equipment is reset, the buffer box baffle 22 reopens, and continues to receive material, realizing cyclical and accurate weighing. After the pre-compression module 4 receives two unloadings from the weighing module 3 (60kg each time, 120kg total), the continuous pre-compression device 42 is activated. The pre-compression hydraulic cylinder 421 drives the pre-compression head 422 to pre-compress the material in the pre-compression box 41 from top to bottom, compressing the material to 1 / 3 of its original volume. The weighing-pre-compression process is repeated, receiving a total of three unloadings (360kg in total), completing three segmented pre-compressions. During this process, the horizontal section of the pusher head 53 prevents the raw material from entering the pusher box 51. The position sensor 43 controls the compression stroke of each pre-compression in real time, gradually reducing the rebound amplitude of the granular cotton and achieving the initial shaping of the material. After the pre-compression module 4 completes three stages of pre-compression, the pusher head 53 retracts, and the bale enters the pusher box 51 from the pre-compression box 41. The shaping baffle cylinder 55 drives the pusher shaping baffle 54 to close, forming a closed extrusion space. Subsequently, the compaction cylinder 52 starts, driving the pusher head 53 to horizontally extrude the material from left to right, achieving final compression molding and compressing the material to a density of about 360 kg / m³. The formed bale is a standard cube with no obvious expansion or deformation. After the material is finally pressed and shaped, the compaction cylinder 52 is started, driving the pusher head 53 to move further, transferring the bale block in the pusher box 51 to the outlet box 61. The shaping baffle cylinder 55 drives the pusher shaping baffle 54 to open, and the outlet pushing cylinder 62 is started, driving the outlet pushing head 63 to push the shaped bale block to the bagging outlet 611. When the position detection switch detects that the bale block has reached the designated position, the outlet pushing cylinder 62 stops running, providing accurate positioning for subsequent bagging operations. The bagging operation is done manually. The operator puts the packaging bag on the bagging outlet 611 in advance and temporarily fixes it with an elastic clamp (such as an elastic clamp). When the bagging pushing cylinder 62 pushes the formed bag block to the bagging outlet 611, the bag block slides directly into the packaging bag along the guide ring on the bagging outlet 611, realizing automatic bagging operation. After bagging is completed, the elastic clamp is released manually or automatically, and the finished bag block is discharged smoothly. There is no need for manual secondary transfer for bagging. Related conveying and guiding devices (such as transmission belts) can be used to realize the transfer of bagged bags.

[0036] It should be noted that the device achieves intelligent control of the buffer module 2, weighing module 3, pre-compression module 4, bag pushing module 5 and bag exiting and bagging module 6 through the whole machine linkage control system. The driving components and detection components are all electrically connected to the linkage control system, realizing full-process automated linkage. Moreover, the control logic is based on the PLC centralized control logic of existing mature technology.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention 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 solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
