Description

Technical Field

[0001] The invention relates to the field of automated assembly production lines, and in particular to a portable sports water-absorbing bag production device and a working method thereof. Background Art

[0002] During the production process of absorbent bags, automated assembly equipment is generally used for production and assembly. Replacing manual labor with automated equipment can effectively avoid human errors. The reason is that the production process of absorbent bags includes an important step, namely, hot pressing the edges of the bag body. Due to the particularity of the material of the absorbent bag, the bag body of the absorbent bag is made of rubber, and the raw material is a whole piece of rubber sheet. During the production process, the whole piece of rubber sheet needs to be folded like origami and then its edges are hot pressed and closed. The principle of hot pressing is to heat the rubber sheet until the surface reaches a molten state and then press it. In this process, there is a problem that is very easy to occur: that is, because the entire rubber sheet raw material is placed in a relatively high temperature environment during the hot pressing process, other areas except the hot pressing part are easily affected by the high temperature and surface adhesion occurs. Once adhesion occurs, it will directly lead to a decrease in the yield rate.

[0003] In the prior patent application, the applicant proposed an automatic assembly equipment for absorbent bags, specifically an automatic assembly equipment for absorbent bags disclosed in Chinese patent application No. 202311411500.X, and in particular, it relates to an automatic assembly equipment for absorbent bags, including an input conveyor belt, a working box and an output conveyor belt. The absorbent bag enters the working box through the input conveyor belt and cooperates with the rotation of the assembly station in the working box to automatically insert the straw, and the upper and lower bag bodies are simultaneously hot-pressed and composited during the transfer by the manipulator, and then the finished absorbent bag is transferred and transported through the output conveyor belt. The equipment is fully automated throughout the process, and is mainly used in the automatic assembly production line of absorbent bags, which solves the technical problem that the existing absorbent bag production and assembly equipment is prone to manual errors and reduced yields due to excessive manual intervention during the working process. The technical solution proposed by the above invention is mainly aimed at the problem that there is a deviation in the installation of the interface due to manual intervention in the production process of the absorbent bag, which may cause a gap in the seal and cause a decrease in the yield rate. Regarding the edge sealing of the bag itself, it does not propose an improvement plan. Summary of the invention

[0004] Therefore, in response to the above problems, the present invention proposes a portable sports absorbent bag production equipment and a working method thereof, which solves the technical problem that the existing absorbent bag production equipment will cause hot melt adhesion to the bag body itself due to the high temperature environment when hot pressing the edge of the bag body, thereby causing the bag body to stick together and the yield to decrease.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a portable sports absorbent bag production equipment, comprising a machine platform, a slide track arranged on the upper surface of the machine platform, a workbench arranged on the slide track, a feed port and a discharge port arranged on the machine platform, a lifting feed platform is arranged in the feed port, a hot pressing device is arranged on the lifting feed platform, the workbench comprises a moving base, a support rod assembly, a functional table hinged to the support rod assembly, an auxiliary mechanical arm arranged on the functional table, and a bag-supporting mechanism is arranged on the functional table;

The inner bag-supporting rod telescopes and moves inside the outer bag-supporting rod along its own axial direction, thereby driving the elastic bag-supporting plate to bulge outward or retract inward. The auxiliary robot arm is a multi-axis robot arm, which can move arbitrarily in three-dimensional space.

[0007] A telescopic shaft is provided at the bottom of the inner cavity of the outer bag supporting rod, and the telescopic shaft is used to connect the bottom of the inner cavity of the outer bag supporting rod and the end of the inner bag supporting rod. An annular groove is provided in the inner cavity of the outer bag supporting rod, and a first thread is provided in the annular groove. A first convex portion is provided on the outer circumferential side surface of the inner bag supporting rod, and a second thread is provided on the first convex portion. The first thread and the second thread are meshed with each other. In horizontal plane projection, the first thread only occupies one-third of the area of ​​the annular groove, and the remaining area is smooth; in horizontal plane projection, the first convex portion only occupies one-half of the area of ​​the outer circumferential side surface of the inner bag supporting rod, and the remaining area is smooth. The elastic bag supporting plate is rotatably connected to the outer bag supporting rod;

[0008] The bag-supporting inner rod is rotated by being driven to rotate by a telescopic shaft connected to a rotating motor.

[0009] Furthermore, dot-shaped protrusions are arranged at intervals on the outer surface of the elastic bag-supporting plate.

[0010] Furthermore, a ventilation hole is provided in the bag-supporting inner rod, and the ventilation hole completely penetrates the bag-supporting inner rod along the axial direction of the bag-supporting inner rod.

[0011] Furthermore, the diameter of the ventilation hole is one eighth of the diameter of the inner rod of the bag support.

[0012] Furthermore, the workbench moves back and forth along the length direction of the slide track driven by a driving motor through a movable base.

[0013] Furthermore, the hot pressing device includes a first hot pressing plate and a second hot pressing plate arranged in a vertical direction on the lifting feeding table, the first hot pressing plate and the second hot pressing plate are arranged opposite to each other, a first cavity is arranged on a side surface of the first hot pressing plate close to the second hot pressing plate, and a second cavity is arranged on a side surface of the second hot pressing plate close to the first hot pressing plate, the first hot pressing plate and the second hot pressing plate are achieved by a driving mechanism to approach or move away from each other, when the first hot pressing plate and the second hot pressing plate are attached to each other, the first cavity and the second cavity are attached to each other to form a molding cavity, a first hot pressing heating strip is arranged around the end edge of the first cavity, and a second hot pressing heating strip is arranged around the end edge of the second cavity, and an auxiliary entrance is arranged on the top of the hot pressing device, and the bag supporting mechanism enters the molding cavity through the auxiliary entrance.

[0014] Furthermore, cooling devices are integrated in the first cavity and the second cavity.

[0015] A working method of a portable sports water-absorbing bag production device comprises the following steps:

[0016] S1, the equipment automatically loads materials; the raw material rubber layer is transported to the hot pressing device through the loading equipment, and the rubber layer includes a left rubber layer and a right rubber layer that are symmetrical to each other and are respectively attached to the first hot pressing plate and the second hot pressing plate;

[0017] S2, the bag-supporting mechanism intervenes; the first hot pressing plate and the second hot pressing plate are separated from each other, and the bag-supporting mechanism extends downward between the first hot pressing plate and the second hot pressing plate;

[0018] S3, edge heat pressing; the first hot pressing plate and the second hot pressing plate approach each other, the first hot pressing heating strip and the second hot pressing heating strip start heating to perform hot pressing, and the bag support mechanism starts working synchronously with the process of the first hot pressing plate and the second hot pressing plate approaching each other;

[0019] S4, hot pressing is completed; after the hot pressing is completed, the bag-supporting mechanism is withdrawn from the hot pressing device, and at the same time, the bag body is preliminarily cooled by the cooling device and then the hot-pressed bag body is transferred to the discharge port by the auxiliary robotic arm.

[0020] Furthermore, in step S3, the working process of the bag-supporting mechanism is that the inner rod of the bag-supporting mechanism rotates relative to the outer rod of the bag-supporting mechanism through the rotating motor. When the first thread and the second thread begin to engage, the inner rod of the bag-supporting mechanism retracts inward and pushes the elastic bag-supporting plate outward. The inner rod of the bag-supporting mechanism continues to rotate until the first thread and the second thread disengage from each other, the inner rod of the bag-supporting mechanism is pushed outward, and the elastic bag-supporting plate returns to its initial state.

[0021] By adopting the above technical solution, the beneficial effects of the present invention are:

[0022] 1. Compared with the existing production equipment for flexible packaging such as absorbent bags, the present invention directly avoids the problem that the state of the surface of flexible materials changes under high temperature environment and partial adhesion occurs, which leads to a decrease in yield rate. Specifically, the present invention proposes an innovative production equipment, mainly improves the equipment through a hot pressing process, adds a bag-supporting mechanism to avoid the adhesion phenomenon, and at the same time uses a multi-axis mechanical arm to transport and transfer the bag body after hot pressing. The bag-supporting mechanism is an innovative structure, which adopts a bag-supporting inner rod and a bag-supporting outer rod that are mutually nested. When working, the bag-supporting mechanism completely enters the bag body to assist in hot pressing. When the hot pressing work is carried out, the temperature in the cavity rises accordingly. At this time, the bag-supporting inner rod rotates along its own axis direction, and during the rotation, it drives the elastic bag-supporting plate to open outward, and then the elastic bag-supporting plate is attached to and opened by the inner surface of the absorbent bag body, avoiding The bag body is prevented from sticking due to the high temperature environment; and as the inner bag support rod rotates continuously in the same direction, it can automatically expand and contract. The principle is that the first thread and the second thread correspondingly arranged on the inner bag support rod and the outer bag support rod are not full-circle designs, but local designs are adopted. This design ensures that when the inner bag support rod rotates continuously, the inner bag support rod will only perform expansion and contraction movement in the axial direction when the first thread and the second thread are engaged, and when the first thread and the second thread are disengaged, it will return to its original state under the joint action of the telescopic shaft and the elastic bag support plate; the reason for this design is that it can ensure that the bag support mechanism only needs one set of transmission system during the working process, so as to realize the bag body entry of the bag support mechanism, the bag body expansion, the elastic bag support plate retracts after the work is completed, and the bag body of the bag support mechanism is disengaged, and this working process is carried out simultaneously with the hot pressing process, and will not increase energy consumption and working time.

[0023] 2. In the present invention, dot-shaped protrusions are arranged at intervals on the outer surface of the elastic bag support plate to reduce the contact area between the elastic bag support plate and the inner side of the bag body, thereby avoiding adhesion between the elastic bag support plate and the inner side of the bag body.

[0024] 3. At the same time, the advantage of the bag-opening mechanism in the present invention is not only that the bag-opening action is performed synchronously during the hot pressing process to avoid heat adhesion. When the inner rod of the bag-opening mechanism rotates, the elastic bag-opening plate rotates synchronously and rotates in contact with the inner side of the bag body. At this time, the temperature in the molding cavity increases, that is, the bag body is in a plastic state. The elastic bag-opening plate performs a rotating bag-opening action at this time, which can also improve the ductility of the bag body, that is, the volume of the bag body can be increased after it is opened.

[0025] 4. In the present invention, ventilation holes are provided in the inner bag-supporting rod. The reason for providing the ventilation holes is that, on the one hand, it is ensured that the inner bag-supporting rod and the outer bag-supporting rod will not interfere with each other in movement due to air pressure problems during the extension and retraction process; on the other hand, when the inner bag-supporting rod retracts inwardly, the compressed air inside the outer bag-supporting rod will be discharged outwardly through the ventilation holes, and the outwardly discharged airflow can directly enter the water-absorbing bag body through the orifices of the ventilation holes, and then can cooperate with the elastic bag-supporting plate to perform the bag-supporting operation on the water-absorbing bag body.

[0026] 5. In the present invention, the aperture of the ventilation hole is set to only one eighth of the rod diameter of the inner rod of the bag support. The purpose is that the heat pressing process takes a certain amount of time, and it is not a rapid heat pressing. Therefore, the working speed of the bag support mechanism needs to be synchronized with the heat pressing device. Therefore, the aperture of the ventilation hole is set to a smaller specification. It can also ensure that during the slow retraction of the inner rod of the bag support, even if the compressed air slowly enters the ventilation hole and is discharged outward, it can also generate a certain air outlet force due to the smaller hole.

[0027] 6. In the present invention, by providing cooling devices in both the first cavity and the second cavity, the bag body can be quickly cooled down when the bag-supporting mechanism is withdrawn after the hot pressing work. The rapid cooling can assist the bag body in rapid demolding, thereby facilitating the transfer and transportation operation of the multi-axis robot arm.

[0028] 7. In the working method for production equipment proposed by the present invention, the particularly important steps are step S3 and step S4, wherein the bag-holding mechanism in step S3 needs to cooperate with the hot pressing device to work synchronously, and the two need to be synchronized and unified to maximize the working efficiency, and in the horizontal plane projection, the first thread only occupies one-third of the annular groove area, and the remaining area is smooth, and the first convex portion, that is, the second thread, only occupies one-half of the outer circumferential side area of ​​the inner rod of the bag-holding, and the remaining area is smooth, and then by reasonably controlling the rotation speed of the inner rod of the bag-holding, it can be ensured that the bag-holding mechanism works synchronously with the hot pressing device, enters the bag body, rotates the bag, and the hot pressing work is also completed synchronously when the bag is pulled out after entering the bag body, and the bag body is cooled and transferred and transported in the next step, and the elastic bag-holding plate has restored its initial state at this time and can immediately carry out the next bag-holding work, and in this process, the driving device of the bag-holding mechanism only has a rotating motor, and all functions of the bag-holding mechanism can be realized by relying only on the unidirectional rotation of the rotating motor.

In this embodiment, water cooling is adopted for cooling.

[0047] This embodiment simultaneously proposes a method for using the above device, specifically:

[0048] A working method of a portable sports water-absorbing bag production device comprises the following steps:

[0049] S1, the equipment automatically loads materials; the raw material rubber layer is transported to the hot pressing device 7 through the loading equipment, and the rubber layer includes a left rubber layer and a right rubber layer symmetrical to each other, which are respectively attached to the first hot pressing plate 71 and the second hot pressing plate 72;

[0050] S2, the bag-holding mechanism intervenes; the first hot pressing plate 71 and the second hot pressing plate 72 are separated from each other, and the bag-holding mechanism 3 extends downward between the first hot pressing plate 71 and the second hot pressing plate 72;

[0051] S3, edge heat pressing; the first heat pressing plate 71 and the second heat pressing plate 72 approach each other, the first heat pressing heating strip and the second heat pressing heating strip start heating to perform heat pressing, and the bag support mechanism starts working synchronously with the process of the first heat pressing plate 71 and the second heat pressing plate 72 approaching each other;

[0052] S4, hot pressing is completed; after the hot pressing is completed, the bag-supporting mechanism 3 is withdrawn from the hot pressing device, and the bag body is initially cooled by the cooling device and then the hot-pressed bag body is transferred to the discharge port 14 by the auxiliary robot arm 2.

[0053] Furthermore, in step S3, the working process of the bag-supporting mechanism 3 is that the bag-supporting inner rod 32 rotates relative to the bag-supporting outer rod 31 through the rotating motor. When the first thread 312 and the second thread 41 begin to engage, the bag-supporting inner rod 32 retracts inward and pushes the elastic bag-supporting plate 33 outward. The bag-supporting inner rod 32 continues to rotate until the first thread 312 and the second thread 41 disengage from each other, the bag-supporting inner rod 32 is pushed outward, and the elastic bag-supporting plate 33 returns to its initial state.

[0054] At the same time, the operating principle of the bag-holding mechanism 3 in the device of the present invention is as follows, which serves as a supplementary explanation of step S3: the outer bag-holding rod 31 and the inner bag-holding rod 32 in the bag-holding mechanism 3 undergo relative axial movement and rotation during operation, wherein the relationship between the outer bag-holding rod 31 and the inner bag-holding rod 32 is similar to the relationship between a bolt and a nut, and while the outer bag-holding rod 31 is kept stationary, the inner bag-holding rod 32 is driven to rotate by a rotating motor, causing the first thread 312 and the second thread 41 to mesh, and during the meshing process, the inner bag-holding rod 32 moves toward the outer bag-holding rod 31, thereby driving the elastic bag-holding plate 33 to undergo metal elastic deformation and be stretched outward, and the first thread 312 and the second thread 41 are not arranged The invention is similar to the fully enclosed arrangement of the bolt and nut, but the first thread 312 occupies only one-third of the inner circumference of the outer bag rod 31, and the second thread 41 occupies only one-half of the outer circumference of the inner bag rod 32. In this way, the first thread 312 and the second thread 41 form an intermittent meshing and separation state as the inner bag rod 32 rotates continuously. When meshing, the inner bag rod 32 and the outer bag rod 31 move axially relative to each other, and when separated, the inner bag rod 32 returns to its original state under the metal elastic deformation of the elastic bag plate 33, and the elastic bag plate 33 returns to its original state. The reason why the rotation after meshing can drive the inner bag rod 32 to move axially is that the principle refers to the up and down movement caused by the rotation of the bolt on the stationary screw.
