Description

Technical Field

[0001] The present invention relates to an apparatus and a method for automatically packing and briquetting bulk rubber, in particular to an apparatus that automatically feeds two pieces of overlapped rubber after weighing, then automatically packs them, and finally automatically discharges a standard finished rubber package, that is, a hydraulic packing machine for bulk rubber and a packing method, belonging to the technical field of automation equipment. Background Art

[0002] With the continuous progress of technology, rubber, as the core raw material for automobile tire production, occupies a large share in the industrial field. In recent years, scientific research scholars have increasingly in-depth research on rubber, and the uses of rubber are also developing in a diversified direction. It can be said that rubber covers almost all aspects of people's daily lives. In recent years, the annual consumption of rubber has been on the rise year by year, and rubber-related manufacturers are also gradually increasing. The production of rubber has gradually developed towards automation, high efficiency and automation.

[0003] The primary processing of rubber is the process of making standard rubber bags through chemical and physical treatment of natural rubber-containing substances. First, the natural latex is collected, then acid coagulated, and the rubber blocks are cleaned using relevant cleaning equipment. Then, the rubber blocks are squeezed and crushed into blocks through some equipment and repeatedly cleaned. Finally, multiple creping processes are carried out. After the creping is completed, the rubber is crushed into blocks by a rubber crusher and dried. Workers weigh the dried rubber according to national standards, and place the rubber with consistent weight but fluffy texture and uneven size into the baler for extrusion and packaging, and finally form standard rubber bags with uniform size, quality, shape and size to feed the downstream industry. Among them, the packaging link is one of the key process links in the production process of standard rubber. This process link requires the weighed rubber blocks (groups) with fluffy texture, excessive volume and irregular shape to be compacted into standard rubber bags of uniform specifications, so that the size of the rubber bags is uniform, the volume is reduced, and it is easy to transport, stack, store and trade. In the field of rubber primary processing, there are currently two links involving packaging, one is the packaging of rectangular rubber blocks after drying, and the other is the packaging of irregular rubber lumps after dry mixing. The current packaging link has a low degree of automation and requires a lot of manual assistance. First, the weighed rubber blocks (lumps) need to be moved to the packaging box manually for packaging. This traditional packaging technology is a semi-automatic operation method. Usually, 2 to 3 people are required on a packaging line (equipped with 2 to 3 packaging machines) to carry and pack the material bags. Due to differences in production organization models, this process section generally requires 3 to 6 people to assist, and the current production mode of rubber processing factories is generally a two-shift system, that is, 6 to 12 people are required to assist in the rubber packaging process. The labor intensity of the work is huge. When the finished rubber is discharged, it is mainly grabbed by the bag nails, and the grabbing is often unstable or unsuccessful. There are great safety hazards when discharging manually.

[0004] In summary, the basic working process of the current baler is:

[0005] (1) Loading stage: Dry rubber blocks of standard weight are manually placed from the weighing table into the feeding device.

[0006] (2) Packing stage: When the push cylinder pushes the right hopper to move below the block, the main cylinder pushes the block downward to a fixed position. The block and the material box form a closed space, squeezing the rubber block for a period of time to complete the packing. At the same time, the packing nail installed below the block is embedded in the rubber bag.

[0007] (3) Out of cavity stage: After the packing is formed, the rubber bag is lifted up while the pressing block is lifted up. The return stroke of the push cylinder drives the hopper to the middle position. After the rubber bag falls, it slides out from the middle roller rail.

[0008] (4) Circulation stage: The return stroke of the push cylinder drives the left hopper to the bottom of the briquette to continue packaging, forming a working mode in which the left and right hoppers alternately circulate and package.

[0009] Through the above work process, it is basically possible to extrude and pack dry rubber packages into standard rubber of a certain size.

[0010] However, there are the following problems with the current method:

[0011] ① Manual feeding. During operation, it is necessary to manually carry rubber blocks (masses) and put them into the hopper of the packing machine, with a relatively high labor intensity. On average, each person needs to carry 12.5 tons of rubber per day.

[0012] ② Difficult to lift the package out of the box. When lifting the package, it is mainly lifted by the lifting nails under the pressed block. Due to the large friction between the rubber package and the inner wall of the hopper, the friction between the lifting nails and the rubber package will decrease as the lifting nails wear, and there will often be a situation where the lifting nails cannot lift the rubber package, that is, the package jamming phenomenon. Once it occurs, it must be removed manually, which is time-consuming and laborious and not easy to operate due to environmental restrictions, and there are safety hazards.

[0013] ③ Generation of process holes. Through the grasping of the lifting nails, process holes will be left on the standard rubber, affecting the appearance quality and also being unfavorable to the uniformity of subsequent rubber cutting and material replenishment.

[0014] Therefore, aiming at the current situation problems of time-consuming, laborious, high safety hazards, high labor intensity, and low automation level encountered by current rubber processing enterprises in the packing link, developing a convenient, safe, and highly automated rubber automatic packing system is the key problem that current rubber production and processing enterprises urgently need to solve. Summary of the Invention

[0015] Aiming at the aforementioned requirements and problems to be solved urgently in the process of realizing automatic rubber packing, the purpose of the present invention is to solve the problems of high safety hazards, low automation level, high labor intensity, irregular package shape, etc. existing in the current automatic packing link of rubber. It uses automated technical means to replace manual production, liberate the labor force, improve the appearance quality, overall efficiency, and automation level of standard rubber packages, so that the standard rubber packages after automated production achieve the purpose of being standard, efficient, fast, and unified, and increase the automated production capacity of rubber standard rubber packages.

[0016] A block rubber hydraulic packing machine and packing method of the present invention can complete automatic feeding, automatic packing, and automatic discharging of the weighed rubber material, and finally form standard rubber packages with uniform size, appearance, etc. It completes the automatic packing process of rubber and solves the problems of low automation level, high labor intensity of workers, and high safety hazards in current rubber processing factories. It can effectively improve the automation and automation level of rubber processing.

[0017] According to the first aspect, the technical solution of the present invention is as follows:

[0018] A block rubber hydraulic baler can realize the automatic feeding and discharging and automatic packing processes of block rubber during the automated rubber production process, and the entire system operates fully automatically. The baler includes a feeding and discharging device, a sealing plate mechanism, universal balls, a discharging roller, a frame, a mobile ladder, a support panel, a packing box mechanism, an upper top plate, connecting columns, and a hydraulic system. Among them:

[0019] The frame is the main support framework of the baler of the present invention; the support panel is fixed above the frame, and the support panel is the main bearing platform of the baler of the present invention; the support panel and the upper top plate are connected into an integral body through the connecting columns, and the upper top plate is the feeding and discharging platform of the baler of the present invention; the feeding and discharging device is arranged on the upper top plate. Through the reciprocating motion of the feeding and discharging device, it can receive the rubber block materials to be packed at the previous process end, send two overlapped rubber block materials to be packed above the packing box, and at the same time, it can also automatically push out the packed finished rubber bales; universal balls are arranged at the discharging port of the upper top plate to reduce the friction between the rubber and the upper top plate, so that the feeding and discharging device can reduce energy consumption when pushing out the finished rubber blocks; the packing box mechanism is arranged on the support panel, and the packing and compressing process of the rubber is carried out inside the packing box. The inner cavity size of the packing box determines the external dimensions of the finished standard rubber bales; the sealing plate mechanism is arranged between the upper top plate and the packing box. The sealing plate mechanism is mainly responsible for opening and closing the feeding and discharging ports of the upper top plate and the packing box. When it is opened, the rubber materials can enter and exit. When it is closed, the rubber materials can be packed and compressed; the discharging roller is fixed on the support panel. The discharging roller is an inclined non-powered roller table structure, and its front section is placed below the universal balls at the discharging port of the upper top plate. It is mainly responsible for receiving the packed finished standard rubber and buffering and conveying the standard rubber to the next process section. The discharging roller belongs to the finished product material outlet of the baler of the present invention; the mobile ladder is arranged on both the left and right sides of the frame. Maintenance workers can climb onto the support panel through the mobile ladder to install, repair, maintain, etc. the equipment; the hydraulic system is independently arranged behind the frame, and the hydraulic system can realize the actions of receiving, packing, and discharging the rubber.

[0020] Further, the pushing mechanism is composed of a guide rail, a feeding and discharging device, a driving motor, a driving sprocket, a slider, a sprocket bracket, a driven sprocket, and a chain; the slider is fixed below the feeding and discharging device, and the feeding and discharging device can move linearly along the guide rail through the slider; the driving motor is fixed at the end of the guide rail, and the driving sprocket is fixed on the output shaft of the driving motor; the sprocket bracket is fixed at the other end of the guide rail, and a driven sprocket with a tensioning function is fixed on the sprocket bracket; one end of the chain is fixed on the side wall of the feeding and discharging device, and the other end bypasses the driving sprocket and the driven sprocket and is then fixed on the side wall of the feeding and discharging device. Through the forward and reverse rotation drive of the driving motor, the chain can generate power under the traction of the driving sprocket and the driven sprocket, and then pull the feeding and discharging device to make a linear reciprocating motion on the guide rail, so as to realize the pushing out of the finished standard rubber bales.

[0021] Furthermore, the feeding and discharging device is a movable feeding and discharging device, which is composed of a guide rail, a slider, a movable bracket, a material blocking comb tooth, a discharging comb tooth, a guiding roller and a conveying roller. The guide rail is fixed on the upper top plate; the slider is fixed at the lower end of the movable bracket, and the whole feeding and discharging device can move linearly back and forth on the guide rail through the slider; a material blocking comb tooth is arranged at one end of the guide rail close to the middle opening of the upper top plate, which is mainly used to block two overlapping rubber blocks to be packed, so that the rubber can accurately enter the packing box; the discharging comb tooth is fixed at the end of the movable bracket. When the movable bracket moves linearly on the guide rail to pick up materials, the packed standard rubber bales can be pushed out through the discharging comb tooth; the guiding rollers are arranged on both sides above the movable bracket, and the guiding rollers are non-powered rollers, which are mainly used to guide and regularize the positions of two overlapping rubber blocks to be packed during the process of conveying them above the packing box, so that the rubber blocks to be packed can accurately fall above the packing box and ensure the alignment accuracy with the material dropping port; the conveying rollers are arranged in the movable bracket, and the two overlapping rubber blocks to be packed can be conveyed to the upper end of the material dropping port of the packing box through the conveying rollers.

[0022] Furthermore, the material blocking comb tooth and the discharging comb tooth in the feeding device utilize the comb tooth exchange technology. When feeding materials, the movable bracket moves to pick up materials at the end of two overlapping rubber blocks after being regularized and weighed. As the movable bracket moves, the material blocking comb tooth and the discharging comb tooth are separated through comb tooth exchange after meeting, and at the same time, the conveying rollers and the guiding rollers also integrate and convey the rubber blocks to above the feeding port of the packing box. The movable bracket slowly retreats in the reverse direction while the conveying rollers continue to convey. The material blocking comb tooth blocks the rubber blocks. When the rubber blocks are completely separated from the conveying rollers, the movable bracket stops running. At this time, the material blocking comb tooth and the discharging comb tooth just meet and overlap again;

[0023] Furthermore, the sealing plate mechanism is a vertically floating linear telescopic mechanism, which is composed of a sealing plate, a cylinder, a rotating hinge, a fixed hinge, universal ball bearings and a guide rail. Universal ball bearings are arranged on the side wall surface of the sealing plate. The cylinder is fixed on the other side wall surface of the sealing plate through the rotating hinge, and the other end of the cylinder is fixed through the fixed hinge. The guide rail is fixed below the upper top plate. The sealing plate can use the universal ball bearings as the contact carriers and move linearly on the guide rail under the driving action of the cylinder. At the same time, under the combined action of the rotating hinge and the fixed hinge, the sealing plate can also perform a certain vertical lifting movement during the linear movement. That is, in the sealing plate mechanism, the sealing plate can realize linear movement in the left-right and up-down directions.

[0024] Furthermore, the packing box mechanism is a scissor-type micro-motion lifting mechanism controlled by a cam, which consists of a packing box, a connecting shaft, a stroke cam, a cam bearing, a driving motor, a motor bracket, a fixed bearing, a scissor shaft, a scissor bearing, a lower sliding seat, a roller and an upper sliding seat. Among them, there are two groups of lower sliding seats as supporting bases. A fixed bearing is arranged on one side of the lower sliding seat, and the fixed bearings are connected through a connecting shaft. The other side of the lower sliding rail serves as a sliding track; a total of four scissor shafts are arranged, paired in pairs, and are connected and fixed at the central position through scissor bearings. After connection, the scissor shafts can rotate relative to each other to achieve a scissor-like rotation similar to scissors. One end of the scissor shaft is connected to the connecting shaft, and the scissor shaft and the connecting shaft can rotate relative to each other. A roller is arranged at the other end of the same scissor shaft. The lower roller can roll linearly on the lower sliding seat, and the upper roller can roll linearly on the upper sliding seat; the upper sliding seat is fixed to one side wall of the packing box. Fixed bearings are arranged in the front-back direction on the other side wall of the packing box, and the fixed bearings are connected through a connecting shaft; that is, one side wall surface of the packing box is fixed through a fixed bearing, and the other side wall surface is placed on the roller through the upper sliding seat, forming a structure in which the scissor shaft supports the packing box; a cam bearing is arranged below the wall surface of the fixed bearing of the packing box; the motor bracket is fixed on the support panel, the driving motor is placed on the motor bracket, and the stroke cam is arranged on the output shaft of the driving motor; the cam bearing located on the packing box is embedded in the stroke cam to form a matching structure with the stroke cam. Through the drive of the driving motor, the stroke cam rotates, thereby driving the cam bearing to move. Under the scissor motion of the scissor shaft, the packing box can achieve a stable vertical lifting motion, and the lifting distance of the lifting motion is controlled by the eccentricity of the stroke cam, and the accurate control of the lifting position can be realized.

[0025] Furthermore, the hydraulic system consists of a hydraulic cylinder, a packing push plate and a hydraulic pump station. The hydraulic pump station is the main power output of the hydraulic system and also the power source for rubber packing and discharging in the present invention; the hydraulic cylinder is fixed on the support panel; the packing push plate is fixed on the hydraulic push rod in the hydraulic cylinder, and the packing push plate can be driven to move vertically through the pushing action of the hydraulic push rod; the packing push plate can realize the functions of receiving materials, packing and discharging under the drive of the hydraulic system.

[0026] Furthermore, the packing box in the packing box mechanism has an open structure at both the upper and lower parts. When the packing box receives materials, the packing push plate in the hydraulic system catches two overlapping rubber block materials and moves downward, so that the rubber block materials to be packed enter the packing box; when the packing box packs, the sealing plate mechanism between the packing box and the upper top plate seals both the upper opening of the packing box and the opening of the upper top plate. The hydraulic system is started to move upward, and the rubber is extruded on the sealing bottom plate through the packing push plate to complete the packing action; when the finished product is discharged, the sealing plate mechanism opens the upper opening of the packing box, the hydraulic system is started to continue to move upward, and the finished product rubber can be pushed out through the packing push plate.

[0027] Furthermore, the sealing plate in the sealing plate mechanism is a hollow opening structure. Under the action of its floating linear extension and retraction, when the rubber is packaged, the sealing plate seals the openings of the packaging box and the upper top plate. Under the action of the travel cam, the packaging box moves upward, so that the upper surface of the sealing plate can be in contact with the upper top plate, ensuring that the packaging box, the sealing plate and the upper top plate are in direct contact, so that the packaging extrusion force generated by the hydraulic system during packaging work directly acts on the upper top plate, preventing the sealing plate from being stressed and increasing the safety of the equipment; when the rubber finished product is discharged, the sealing plate is retracted to align the opening of the sealing plate with the upper opening of the packaging box, and the other structures are consistent with those during packaging, which can ensure that the friction generated between the rubber and the side wall of the packaging box when the finished product is discharged is borne by the upper top plate, effectively protecting the cam structure.

[0028] Furthermore, the operation of the hydraulic baler is mainly controlled based on the PLC system. A material incoming detection sensor is provided at the front end of the conveying roller. When it detects that the block rubber material has completely entered, it controls the start and stop of the front feeding section, and controls the linear motion of the conveying roller at the same time; a conveying roller in-position detection sensor is provided at the discharging comb tooth end, which is used to detect whether the linear motion of the conveying roller is in-position. After detecting the in-position signal, the conveying roller is stopped, and the roller in the conveying roller is controlled to start, so that the rubber material is run until it contacts the material blocking comb teeth, and the conveying roller is controlled to move in the opposite direction while conveying the block rubber, so as to realize the exchange of the block rubber material from the conveying roller to the hydraulic cylinder push plate that has been extended to the limit position; a block rubber material receiving detection sensor is provided on the cylinder push plate, which is used to control the start of the hydraulic cylinder and control the hydraulic cylinder to bring the material into the packing box; an in-position detection sensor is provided at the zero position of the hydraulic cylinder to detect whether the packing cylinder in place, and controls the operation of the sealing plate mechanism after detecting the in-place signal; a sealing plate in-place detection sensor is provided on the sealing plate mechanism, which is used to detect whether the sealing plate is in place when it is extended, and controls the start and stop of the packing box mechanism; a packing box in-place detection sensor is provided above the packing box mechanism, which is used to detect whether the packing box is in place, and control the start of the hydraulic cylinder to extrude and pack the rubber, and return to the initial position after completing the packing action; an in-place detection sensor is provided at the initial position of the packing cylinder, which is used to detect whether the packing is completed and control the packing box and the sealing plate to return to zero position, and a detection sensor is provided at the zero return position of the two, which is used to detect whether the two are returned to zero and in place, and control the packing cylinder to push the material out of the box action; an in-place detection sensor is provided at the movement limit position of the packing cylinder, which is used to detect whether the packing cylinder pushes the finished rubber bag out of the box, and at the same time controls the operation of the conveying roller, and pushes the finished rubber bag onto the discharging conveying roller through the discharging comb teeth.

[0029] Furthermore, the PLC control system cooperates with each detection sensor device to control the operation of the entire system, and the detection sensors at each moving component work according to the functions described. The PLC control system is respectively connected to the feeding and discharging device, the sealing plate mechanism, the packing box mechanism and the hydraulic system through control lines; it is used to achieve: when the baler is working, control the feeding and discharging device to move to dock with the upper-level process system to receive materials and transport the rubber blocks to the packing push plate of the hydraulic system; control the sealing plate of the sealing plate mechanism to push out to seal the opening of the packing box and the upper top plate; after the sealing plate is in place detection sensor detects a signal, the PLC system controls the packing box mechanism to move the packing box upward; after the packing box moves up and the detection sensor detects a signal, the PLC system controls The hydraulic system starts to squeeze and pack the rubber in the packing box. After the squeezing and packing are completed, the packing cylinder returns to zero position. After the packing cylinder zero return detection sensor detects a signal, the PLC control system controls the packing box and the sealing plate to return to zero position in sequence. After the packing box and the sealing plate zero return detection sensor detect a signal, the PLC control system controls the packing box to move up. After the packing box upward movement detection sensor detects a signal, the PLC control system controls the packing cylinder to start running again to the limit position to push out the standard rubber product that has been packaged. When the detection sensor at the limit position of the packing cylinder detects a signal, the PLC system controls the push plate to start running to push out the finished rubber and push the finished rubber bag onto the discharge conveyor roller. Then the PLC control system controls all other components in the hydraulic baler to return to the initial zero position and wait for the next packaging process.Specifically, the hydraulic baler is mainly intelligently controlled by a PLC system. Detection devices are provided at the starting and ending positions of each moving component. When the baler is working: after the feeding detection device detects that the block rubber material enters and moves to the specified position, the PLC system controls the movement of the packing oil cylinder. The block rubber material moves together with the packing oil cylinder and falls into the packing box. When the detection device detects that the block rubber material has moved in place, the PLC system controls the cylinder of the sealing plate mechanism to push out the sealing plate to seal the openings of the packing box and the upper top plate. After the sealing plate in-place detection device detects the sealing signal, the PLC control system controls the operation of the packing box drive motor. Under the action of the scissor structure and the cam, the packing box moves upward. After the upward movement detection device detects the signal, the PLC control system immediately controls the packing oil cylinder to start running to perform the extrusion and packing action on the rubber in the packing box. After the extrusion and packing are completed, the PLC control system controls all relevant executing components to return to the initial zero position. At the same time, the PLC system controls the packing oil cylinder to run again from the zero position to push out the standard rubber finished product that has been packed. When the discharging detection device detects the signal, the PLC control system controls the conveying roller to push out the finished rubber bale to the discharging conveying roller through the pushing comb teeth, realizing the discharging of the finished rubber bale. Immediately, the PLC control system controls all other components in the hydraulic baler to return to the initial zero position and controls the conveyor at the front end of the hydraulic baler to supply materials to the baler. After the detection device on the conveying roller detects the material signal, the PLC system controls the conveying roller to return, and at the same time controls the roller path in the conveying roller to move, conveying the block material to contact the baffle comb teeth. After detecting the signal of the material contacting the baffle comb teeth, the PLC system controls the conveying roller to run in the reverse direction again, and the roller path in the conveying roller keeps rotating, that is, the PLC system is used to realize the exchange of the block rubber material to be packed from the conveying roller to the push plate of the packing oil cylinder. Immediately, the PLC system repeats the control to perform the next packing work.

[0030] According to the second aspect, a method for packing block rubber of the present invention is specifically as follows:

[0031] S1. Two overlapping rubber block materials that have been regularized and weighed are conveyed by the upper-level process system. The feeding and discharging device moves to dock with the upper-level process system for feeding.

[0032] S2. After the feeding is completed, the feeding and discharging device returns and stops when the conveying roller is about to contact the baffle comb teeth. During this process, the baffle comb teeth and the discharging comb teeth are separated through comb tooth exchange. Under the guidance and conveyance of the guide roller and the conveying roller, the rubber block material moves above the feeding port of the packing box and contacts the baffle comb teeth.

[0033] S3. Subsequently, the feeding and discharging device runs in the reverse direction again. During the running process, the conveying rollers continuously convey the rubber block materials to ensure that the rubber blocks do not separate from the material blocking comb teeth. When the feeding and discharging device moves to the point where the material blocking comb teeth and the discharging comb teeth meet again, all the rubber block materials have separated from the conveying rollers and fallen onto the packing push plate of the hydraulic system.

[0034] S4. Subsequently, the hydraulic system is started, causing the packing push plate to return to the initial zero position. Two overlapping rubber block materials fall with the packing push plate and enter the packing box.

[0035] S5. After the two overlapping rubber block materials enter the packing box, the sealing plate mechanism starts to operate. That is, the sealing plate cylinder pushes the sealing plate to seal the feeding port, enclosing the packing box into a sealed cavity.

[0036] S6. The drive motor in the packing box mechanism runs, causing the cam to move. Driven by the cam and the scissor structure, the packing box moves upward to ensure direct contact among the packing box, the sealing plate, and the upper top plate, so that the packing pressure during extrusion packing is borne by the upper top plate.

[0037] S7. Subsequently, the hydraulic system is started, and the packing push plate moves upward to extrude and pack the two overlapping rubber block materials with the sealing plate as the supporting bottom plate. The packing pressure is borne by the upper top plate, completing the extrusion packing work of the rubber.

[0038] S8. When the hydraulic packing pressure reaches the extrusion rated pressure of the standard rubber bale, the packing push plate stays at this position for a certain time to maintain the pressure on the standard rubber bale, and then the packing push plate moves downward to return to the initial zero position.

[0039] S9. Immediately, the drive motor in the packing box mechanism runs, causing the cam to move. Driven by the cam and the scissor structure, the packing box moves downward to return to the initial position, separating the packing box, the sealing plate, and the upper top plate from each other to create a clearance for the sealing plate to return to zero.

[0040] S10. The sealing plate cylinder operates to pull back the sealing plate, causing the sealing plate to return to the zero position to ensure that the opening of the sealing plate is aligned with the opening of the upper top plate, creating space for the standard rubber bale to exit the box.

[0041] S11. The drive motor in the packing box mechanism runs, causing the cam to move. Driven by the cam and the scissor structure, the packing box moves upward to ensure direct contact among the packing box, the sealing plate, and the upper top plate, so that the friction between the rubber and the packing box that needs to be overcome when discharging the standard rubber bale is borne by the upper top plate, and the cam is not stressed when pushing the rubber out of the box.

[0042] S12. The hydraulic system is started, causing the packing push plate to move upward to the extreme limit position of the hydraulic system to push out the finished standard rubber bale in the packing box.

[0043] S13. After the hydraulic press head pushes the finished rubber bale to the extreme position, the feeding and discharging device operates. The finished rubber bale is directly pushed out through the discharging comb teeth and directly falls into the discharging roller through the universal ball, completing the discharging of the finished rubber bale. At the same time, the feeding and discharging device moves to dock with the previous process conveyor line to prepare to receive the next two overlapping rubber block materials to be packed.

[0044] S14. During the discharging process, the drive motor in the packing box mechanism operates to move the cam. Driven by the cam and the scissor structure, the packing box moves downward to return to the initial position, separating the packing box, the sealing plate, and the upper top plate from each other, leaving a moving space for the sealing of the sealing plate, and then starting the next packing operation.

[0045] S15. Through the above steps S1 to S14, the automatic processes of receiving, feeding, dropping, squeezing and packing, and discharging the two weighed and overlapping rubber block materials coming out of the water line are completed.

[0046] The working principle of the present invention:

[0047] A block rubber hydraulic baler and a baling method, mainly composed of a feeding and discharging device, a sealing plate mechanism, universal balls, a discharging roller, a frame, a movable ladder, a support panel, a packing box mechanism, an upper top plate, connecting columns and a hydraulic system. Among them, the frame is the main support frame of the baler of the present invention; the support panel is the main bearing platform of the baler of the present invention; the connecting columns are the main stress-bearing columns, connecting the support panel and the upper top plate into one body; the upper top plate is a hollow structure, responsible for the feeding and discharging of rubber; the feeding and discharging device is mainly responsible for receiving, feeding, discharging and automatically discharging the finished rubber bales of two overlapping rubber blocks to be baled; the universal balls are used to reduce the friction between the rubber discharging and the upper top plate, and reduce the energy consumption when the feeding and discharging device pushes out the finished rubber bales; the packing box mechanism has the function of micro-movement lifting through the scissor principle of the cam and scissor structure, and the rubber is baled and compressed in the packing box, and the outer dimensions of the finished standard rubber bales are determined by the inner cavity dimensions of the packing box; the sealing plate mechanism is connected to the cylinder through a hinge, and can realize the linear movement of up and down micro-movement, mainly responsible for opening and closing the feeding and discharging ports of the upper top plate and the packing box. When opened, the rubber material can enter and exit. When closed, the rubber material can be baled and compressed; the discharging roller is the finished product material outlet of the baler of the present invention, mainly responsible for receiving the packed finished standard rubber and buffer transporting the standard rubber to the next process section; the movable ladder is the maintenance passage of the baler of the present invention, and workers can go to the support panel through the movable ladder to install, maintain and repair the equipment, etc.; the hydraulic system is the core power source for realizing baling and discharging of the present invention, and can realize the actions of receiving, baling and discharging rubber. When automatically baling two overlapping rubber blocks that have been weighed through this system, the two overlapping rubber blocks after being sorted and weighed are transported by the upper-level process system. The feeding and discharging device moves to dock with the upper-level process system for receiving materials; after receiving the materials, the feeding and discharging device returns and stops when the conveying roller is about to contact the baffle comb teeth. During this process, the baffle comb teeth and the discharging comb teeth are separated through the comb teeth exchange. Under the guidance and transportation of the guiding roller and the conveying roller, the rubber blocks move above the feeding port of the packing box and contact the baffle comb teeth; then the feeding and discharging device runs in the reverse direction again. During the running process, the conveying roller continuously transports the rubber blocks to ensure that the rubber blocks do not break away from the baffle comb teeth. When the feeding and discharging device moves to the point where the baffle comb teeth and the discharging comb teeth meet again, the rubber blocks have all separated from the conveying roller and fallen on the packing push plate of the hydraulic system; then the hydraulic system is started, so that the packing push plate returns to the initial zero position, and the two overlapping rubber blocks fall with the packing push plate and enter the packing box; after the blanking is completed, the sealing plate cylinder pushes the sealing plate to seal the feeding port and closes the packing box into a sealed cavity; the drive motor in the packing box mechanism runs, so that the cam moves. Under the drive of the cam and the scissor structure, the packing box moves upward to ensure that the packing box, the sealing plate and the upper top plate are in direct contact, so that the packing pressure during extrusion and baling is borne by the upper top plate;Subsequently, the hydraulic system is started, and the packing push plate moves upward. With the sealing plate as the supporting bottom plate, the two overlapping rubber blocks are extruded and packed. The packing pressure is borne by the upper top plate to complete the extrusion and packing work of the rubber. When the hydraulic packing pressure reaches the rated extrusion pressure of the standard rubber bale, the packing push plate stays at this position for a certain period of time to maintain the pressure on the standard rubber bale, and then the packing push plate moves downward to return to the initial zero position. Immediately, the drive motor in the packing box mechanism runs to make the cam move. Driven by the cam and the scissor structure, the packing box moves downward to return to the initial position, separating the packing box, the sealing plate and the upper top plate from each other to create a gap for the sealing plate to return to zero. The sealing plate cylinder runs to pull back the sealing plate to make the sealing plate return to the zero position, ensuring that the opening of the sealing plate is aligned with the opening of the upper top plate to create space for the standard rubber bale to exit the box. The drive motor in the packing box mechanism runs to make the cam move. Driven by the cam and the scissor structure, the packing box moves upward to ensure direct contact among the packing box, the sealing plate and the upper top plate, so that the friction between the rubber and the packing box that the standard rubber bale needs to overcome during discharging is borne by the upper top plate, and the cam is not stressed when pushing the rubber out of the box. Subsequently, the hydraulic system is started, and the packing push plate moves upward to the extreme limit position of the hydraulic system to push out the finished standard rubber bale in the packing box. Then the feeding and discharging device runs, directly pushing out the finished rubber bale through the discharging comb teeth and directly falling into the discharging roller through the universal balls to complete the discharging of the finished rubber bale. At the same time, the feeding and discharging device moves to dock with the previous process conveying line to prepare for receiving the next two overlapping rubber blocks to be packed. During the discharging process, the drive motor in the packing box mechanism runs to make the cam move. Driven by the cam and the scissor structure, the packing box moves downward to return to the initial position, separating the packing box, the sealing plate and the upper top plate from each other to create a movement gap for the sealing of the sealing plate, and then the next packing work starts.;

[0063] Embodiment 1

[0064] A block rubber hydraulic packing machine and a packing method can realize the process of automatic feeding and discharging and automatic packing of rubber during the automatic production process of rubber. The whole system is fully automated, solving the problems of low automation level, high labor intensity of workers and high safety hazards in current rubber processing factories. It can effectively improve the automation level of rubber processing.

[0065] As Figure 1 and Figure 2 shown, the packing machine is mainly provided with a feeding and discharging device 1, a sealing plate mechanism 2, a universal ball 3, a discharging roller 4, a frame 5, a movable ladder 6, a support panel 7, a packing box mechanism 8, an upper top plate 9, a connecting pillar 10, and a hydraulic system 11. Each structural member is connected according to the positional relationship described above. During installation, the frame 5 is directly fixed on the ground as the main support frame of the machine; the support panel 7 is fixed above the frame 5; the connecting pillar 10 connects the support panel 7 and the upper top plate 9; the feeding and discharging device 1 is fixed on the upper top plate 9; a universal ball 3 is arranged at the discharging port of the upper top plate 9 to reduce the friction between the rubber and the upper top plate 9; the packing box mechanism 8 is arranged on the support panel 7, and the inner cavity size of the packing box 801 can determine the outer shape size of the finished standard rubber package; the sealing plate mechanism 2 is arranged between the upper top plate 9 and the packing box 801; the discharging roller 4 is directly fixed on the support panel 7 as the finished product outlet of the equipment, and the front end is placed below the universal ball 3 at the discharging port of the upper top plate 9; the movable ladder 6 is the maintenance passage of the machine, and workers can go to the support panel 7 through the movable ladder 6 to install, repair, maintain the equipment, etc.; the hydraulic system 11 is the core power source for realizing packing and discharging in the present invention, and can realize the actions of receiving rubber, packing and discharging.

[0066] As Figure 7 shown, the structure of the feeding and discharging device 1 is a movable support structure, which is composed of a first guide rail 101, a slider 102, a movable support 103, a baffle comb 104, a discharging comb 105, a guide roller 106 and a conveying roller 107. As shown in the appendix Figure 7As shown in the figure, the first guide rail 101 is fixed on the upper top plate 9; the slider 102 is fixed at the lower end of the movable bracket 103, and the slider 102 can move on the first guide rail 101; a material blocking comb 104 is arranged at the position where the upper top plate 9 has a middle opening; the discharging comb 105 is fixed at the end of the movable bracket 103 and can push out the packaged standard rubber bales; the guiding rollers 106 are arranged on both sides above the movable bracket 103 and can correct and regularize the position of the material; the conveying rollers 107 are arranged in the movable bracket 103 and can convey the rubber material to be packaged. The material blocking comb 104 and the discharging comb 105 utilize the comb tooth exchange technology. During feeding, the movable bracket 103 moves to pick up the material at the end of two overlapping rubber blocks after regularizing and weighing. As the movable bracket 103 moves, the material blocking comb 104 and the discharging comb 105 are separated through comb tooth exchange after meeting, and at the same time, the conveying rollers 107 and the guiding rollers 106 also integrate and convey the rubber blocks above the feeding port of the packing box 801. The movable bracket 103 slowly retreats in the reverse direction while the conveying rollers 107 continue to convey. The material blocking comb 104 blocks the rubber blocks. When the rubber blocks completely leave the conveying rollers 107, the movable bracket 103 stops running. At this time, the material blocking comb 104 and the discharging comb 105 just meet and overlap again;

[0067] As Figure 4 shown, the structure of the sealing plate mechanism 2 is a vertically floating linear telescopic mechanism, which is composed of a sealing plate 201, a cylinder 202, a rotating hinge 203, a fixed hinge 204, a universal ball 205, and a second guide rail 206. A universal ball 205 is arranged on the side wall surface of the sealing plate 201. The cylinder 202 is fixed on the other side wall surface of the sealing plate 201 through the rotating hinge 203. The other end of the cylinder 202 is fixed through the fixed hinge 204. The second guide rail 206 is fixed below the upper top plate 9. The sealing plate 201 can take the universal ball 205 as the contact carrier and perform linear motion on the second guide rail 206 under the driving action of the cylinder 202. At the same time, under the combined action of the rotating hinge 203 and the fixed hinge 204, the sealing plate 201 can also perform a certain vertical lifting motion during the horizontal linear motion. That is, in the sealing plate mechanism 2, the sealing plate 201 can realize the vertically floating linear telescopic motion.

[0068] As Figure 5As shown in the figure, the structure of the packing box mechanism 8 is a scissor-type micro-motion lifting mechanism controlled by a cam stroke, which is composed of a packing box 801, a connecting shaft 802, a stroke cam 803, a cam bearing 804, a driving motor 805, a motor bracket 806, a fixed bearing 807, a scissor shaft 808, a scissor bearing 809, a lower sliding seat 810, a roller 811 and an upper sliding seat 812. There are two groups of lower sliding seats 810. A fixed bearing 807 is arranged on one side of the lower sliding seat 810, and the fixed bearings 807 are connected by a connecting shaft 802. The lower sliding seat 810 on the other side serves as a sliding track. A total of four scissor shafts 808 are arranged, paired in pairs, and are connected and fixed at the central position by scissor bearings 809. After connection, the scissor shafts 808 can perform scissor rotation similar to scissors. One end of the scissor shaft 808 is connected to the connecting shaft 802, and a roller 811 is arranged at the other end. The roller 811 at the lower end can roll linearly on the lower sliding seat 810, and the roller 811 at the upper end can roll linearly on the upper sliding seat 812. The upper sliding seat 812 is fixed on one side wall of the packing box 801. Fixed bearings 807 are arranged in the front and back directions on the other side wall of the packing box 801, and the fixed bearings 807 are connected by a connecting shaft 802. The cam bearing 804 is arranged on the packing box 801. The motor bracket 806 is fixed on the support panel 7, the driving motor 805 is placed on the motor bracket 806, and the stroke cam 803 is arranged on the output shaft of the driving motor 805. The cam bearing 804 located on the packing box 801 is embedded in the stroke cam 803 to form a matching structure with the stroke cam 803. Driven by the driving motor 805, the stroke cam 803 rotates, thereby driving the cam bearing 804 to move. Under the scissor movement of the scissor shaft 808, the packing box 801 can perform a stable vertical lifting movement, and the lifting distance is controlled by the eccentricity of the stroke cam 803, and accurate control of the lifting position can be achieved.

[0069] As Figure 6 shown, the sealing plate mechanism 2 and the packing box mechanism 8 cooperate with each other to perform opening and sealing actions, that is, the sealing plate mechanism 2 is arranged above the packing box mechanism 8. When the packing box mechanism 8 moves and the packing box 801 moves upward, the packing box 801 will first contact the sealing plate 201, and continue to push the sealing plate 201 upward during the continuous upward movement until the packing box 801, the sealing plate 201 and the upper top plate 9 are in contact with each other. When the packing box 801 is at the lowest position, there are gaps between the packing box 801, the sealing plate 201 and the upper top plate 9. As shown in the appendix Figure 3 shown, at this time, the sealing plate mechanism 2 can freely expand and contract to open and close the openings of the packing box 801 and the upper top plate 9.

[0070] As Figure 8As shown, the hydraulic system 11 is composed of a hydraulic cylinder 1101, a packing push plate 1102 and a hydraulic pump station 1103. The hydraulic pump station 1103 is the power source for rubber packing and discharging in the machine; the hydraulic cylinder 1101 is fixed on the support panel 7; the packing push plate 1102 is fixed on the hydraulic push rod in the hydraulic cylinder 1101, and the packing push plate 1102 can be driven to move vertically through the pushing action of the hydraulic push rod; the packing push plate 1102 can realize the functions of receiving, packing and discharging materials under the drive of the hydraulic system 11.

[0071] The invention relates to a sealing plate mechanism 2 and a packing box mechanism 8 in a block rubber hydraulic packing machine and a packing method. The sealing plate mechanism 2 is not limited to the use of a cylinder 202 to push the sealing plate 201 to achieve the linear extension and retraction of the sealing plate 201, and can also use a gear rack structure, a hydraulic mechanism, an electric push rod structure, etc. to achieve the linear extension and retraction of the sealing plate 201; the micro-motion lifting of the packing box mechanism 8 is not limited to the use of a scissor-type structure, and can also use a cylinder 202 structure, an electric push rod and other structures combined with a slider 1205, a linear bearing and other actuators to achieve the purpose of micro-motion lifting when the processing accuracy and assembly accuracy are met.

[0072] Example 2

[0073] A block rubber hydraulic baler and baling method, in order to realize the automatic feeding, baling and discharging functions of rubber, the specific implementation steps are as follows:

[0074] At the beginning of S1, two overlapping rubber blocks that have been shaped and weighed are transported from the previous process system, and the feeding and discharging device 1 moves to dock with the previous process system to receive the materials;

[0075] After S2 completes the material receiving, the feeding and discharging device 1 returns to the conveying roller 107 and stops when it is about to contact the material-blocking comb teeth 104. During this process, the material-blocking comb teeth 104 and the material-discharging comb teeth 105 are separated by comb tooth exchange. Under the guidance and transportation of the guide roller 106 and the conveying roller 107, the rubber block material moves to the top of the feeding port of the packing box 801 and contacts the material-blocking comb teeth 104.

[0076] S3 The feeding and discharging device 1 runs in the reverse direction again. During the operation, the conveying roller 107 continuously conveys the rubber block material to ensure that the rubber block does not separate from the material-blocking comb teeth 104. When the feeding and discharging device 1 moves to the point where the material-blocking comb teeth 104 and the discharging comb teeth 105 meet again, the rubber block material has completely separated from the conveying roller 107 and falls on the packing push plate 1102 of the hydraulic system 11.

[0077] S4 Then the hydraulic system 11 is started to make the packing push plate 1102 return to the initial zero position, and the two overlapping rubber blocks fall along with the packing push plate 1102 and enter the packing box 801;

[0078] After two overlapping rubber blocks enter the packing box 801, the sealing plate mechanism 2 starts to operate. That is, the air cylinder 202 pushes the sealing plate 201 to make the sealing plate 201 extend, sealing the feeding port of the upper top plate 9 and the packing box 801, and enclosing the packing box 801 into a sealed cavity;

[0079] S6 The drive motor 805 in the packing box mechanism 8 operates, causing the stroke cam 803 to move. Driven by the stroke cam 803 and the scissor structure, the packing box 801 moves upward to ensure direct contact among the packing box 801, the sealing plate 201, and the upper top plate 9, so that the packing pressure during extrusion packing is borne by the upper top plate 9;

[0080] S7 Subsequently, the hydraulic system 11 is started, and the packing push plate 1102 moves upward to extrude and pack the two overlapping rubber blocks with the sealing plate 201 as the supporting bottom plate. The packing pressure is borne by the upper top plate 9, completing the extrusion packing work of the rubber;

[0081] S8 When the hydraulic packing pressure reaches the extrusion rated pressure of the standard rubber bale, the packing push plate 1102 stays at this position for a certain time to keep the pressure on the standard rubber bale, and then the packing push plate 1102 moves downward to return to the initial zero position;

[0082] S9 Immediately, the drive motor 805 in the packing box mechanism 8 operates, causing the stroke cam 803 to move. Driven by the stroke cam 803 and the scissor structure, the packing box 801 moves downward to return to the initial position, separating the packing box 801, the sealing plate 201, and the upper top plate 9 from each other, creating a clearance for the sealing plate 201 to return to zero;

[0083] S10 The air cylinder 202 in the sealing plate mechanism 2 operates to pull back the sealing plate 201, making the sealing plate 201 return to the zero position, ensuring that the opening of the sealing plate 201 is aligned with the opening of the upper top plate 9, creating space for the standard rubber bale to exit the box;

[0084] S11 The drive motor 805 in the packing box mechanism 8 operates, causing the stroke cam 803 to move. Driven by the stroke cam 803 and the scissor structure, the packing box 801 moves upward to ensure direct contact among the packing box 801, the sealing plate 201, and the upper top plate 9, so that the friction between the rubber and the packing box 801 that needs to be overcome when the standard rubber bale exits the box is borne by the upper top plate 9, and the cam is not stressed when pushing the rubber out of the box;

[0085] S12 The hydraulic system 11 is started to make the packing push plate 1102 move upward to the extreme limit position of the hydraulic system 11, pushing out the finished standard rubber bale in the packing box 801;

[0086] After the hydraulic press head pushes the finished rubber bale to the limit position, the feeding and discharging device 1 operates, directly pushing out the finished rubber bale through the discharging comb teeth 105, and directly falling into the discharging roller 4 through the universal balls 3, completing the discharging of the finished rubber bale. At the same time, the feeding and discharging device 1 moves to dock with the previous process conveying line, preparing to receive two overlapping rubber block materials to be packed next. Through the feeding and discharging device 1, feeding and discharging can be carried out simultaneously;

[0087] S14 During the discharging process, the drive motor 805 in the packing box mechanism 8 operates, causing the stroke cam 803 to move. Driven by the stroke cam 803 and the scissor structure, the packing box 801 moves downward to the initial position, ensuring that the packing box 801, the sealing plate 201, and the upper top plate 9 are separated from each other, leaving a movement gap for the sealing of the sealing plate 201, and then starting the next packing operation;

[0088] S15 Through the above steps S1 to S14, the automatic feeding, feeding, dropping, squeezing and packing, and discharging processes of two overlapping rubber block materials that have been weighed and completed from the water line are completed.

The bulk rubber hydraulic baler according to any one of claims 1-7, characterized in that: It further includes a PLC control system, and the PLC control system is respectively connected to the feeding and discharging device (1), the sealing plate mechanism (2), the packing box mechanism (8), and the hydraulic system (11) through control lines; it is used to realize: when the baler is working, controlling the feeding and discharging device (1) to move to dock with the upper-level process system for receiving materials and transporting the rubber blocks to the packing push plate (1102) of the hydraulic system (11); controlling the sealing plate of the sealing plate mechanism (2) to push out to seal the openings of the packing box and the upper top plate; controlling the packing box mechanism (8) to lift the packing box; controlling the hydraulic system (11) to start to extrude and pack the rubber in the packing box; controlling the push plate to run to push out the finished rubber.

9. The packing method of a bulk rubber hydraulic baler according to claim 4, characterized in that, it includes the following steps: S1. Two overlapping rubber block materials that have been regularized and weighed are transported from the upper-level process system, and the feeding and discharging device (1) moves to dock with the upper-level process system for receiving materials; S2. After completing the material receiving, the feeding and discharging device (1) returns and stops when the conveying roller (107) is about to contact the material blocking comb teeth (104). During this process, the material blocking comb teeth (104) and the discharging comb teeth (105) are separated by comb teeth exchange, and under the guiding and conveying of the guiding roller (106) and the conveying roller (107), the rubber block material moves above the feeding port of the packing box (801) and contacts the material blocking comb teeth (104); S3. The feeding and discharging device (1) runs in the reverse direction again. During the running process, the conveying roller (107) continuously conveys the rubber block materials, ensuring that the rubber blocks do not break away from the material retaining comb teeth (104). When the feeding and discharging device (1) moves to the point where the material retaining comb teeth (104) and the discharging comb teeth (105) meet again, all the rubber block materials have completely separated from the conveying roller (107) and fallen onto the packing push plate (1102) of the hydraulic system (11). S4. Subsequently, the hydraulic system (11) is started, causing the packing push plate (1102) to return to the initial zero position. Two overlapping rubber block materials fall with the packing push plate (1102) and enter the packing box (801). S5. After the two overlapping rubber block materials enter the packing box (801), the cylinder (202) pushes the sealing plate (201), causing the sealing plate (201) to extend and seal the feeding opening of the upper top plate (9) and the packing box (801), enclosing the packing box (801) into a sealed cavity. S6. The drive motor (805) in the packing box mechanism (8) runs, causing the stroke cam (803) to move. Under the drive of the stroke cam (803) and the scissor structure, the packing box (801) moves upward, ensuring direct contact among the packing box (801), the sealing plate (201), and the upper top plate (9), so that the packing pressure during extrusion packing is borne by the upper top plate (9). S7. Subsequently, the hydraulic system (11) is started, and the packing push plate (1102) moves upward. Using the sealing plate (201) as the supporting bottom plate, the two overlapping rubber block materials are extruded and packed. The packing pressure is borne by the upper top plate (9), completing the extrusion packing work of the rubber. S8. When the hydraulic packing pressure reaches the extrusion rated pressure of the standard rubber bale, the packing push plate (1102) maintains a certain time to keep the pressure on the standard rubber bale, and then the packing push plate (1102) moves downward to return to the initial zero position. S9. Immediately, the drive motor (805) in the packing box mechanism (8) runs, causing the stroke cam (803) to move. Under the drive of the stroke cam (803) and the scissor structure, the packing box (801) moves downward to return to the initial position, separating the packing box (801), the sealing plate (201), and the upper top plate (9) from each other, creating a gap for the sealing plate (201) to return to zero. S10. The cylinder (202) in the sealing plate mechanism (2) runs, pulling back the sealing plate (201) to make the sealing plate (201) return to zero, ensuring that the opening of the sealing plate (201) is aligned with the opening of the upper top plate (9), creating space for the standard rubber bale to exit the box. S11. The drive motor (805) in the packing box mechanism (8) runs, causing the stroke cam (803) to move. Under the drive of the stroke cam (803) and the scissor structure, the packing box (801) moves upward, ensuring direct contact among the packing box (801), the sealing plate (201), and the upper top plate (9), so that the friction between the rubber and the packing box (801) that the standard rubber bale needs to overcome when exiting the box is borne by the upper top plate (9), and the cam is not stressed when pushing the rubber out of the box. S12. The hydraulic system (11) is started, causing the packing push plate (1102) to move upward to the extreme position of the hydraulic system (11), and pushing out the finished standard rubber bales in the packing box (801). S13. After the hydraulic press head pushes the finished rubber bales to the extreme position, the feeding and discharging device (1) operates, directly pushing out the finished rubber bales through the discharging comb teeth (105), and directly falling into the discharging roller (4) through the universal balls (3), completing the discharging of the finished rubber bales. At the same time, the feeding and discharging device (1) moves to dock with the previous process conveyor line, preparing to receive the next two overlapping rubber block materials to be packed. Through the feeding and discharging device (1), feeding and discharging can be carried out simultaneously. S14. During the discharging process, the drive motor (805) in the packing box mechanism (8) operates, causing the stroke cam (803) to move. Driven by the stroke cam (803) and the scissor structure, the packing box (801) moves downward to the initial position, ensuring the separation of the packing box (801), the sealing plate (201), and the upper top plate (9), leaving a movement gap for the sealing of the sealing plate (201), and then starting the next packing work. S15. Through the above steps S1 to S14, the automatic processes of receiving, feeding, dropping, squeezing and packing, and discharging the two weighed and overlapping rubber block materials coming out of the water line are completed.
