DETAILED DESCRIPTION

[0023] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0024] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0025] In the present application, unless otherwise stated, the orientation words such as "up, down, top, bottom" are generally directed to the direction shown in the drawings, or are directed to the vertical, perpendicular or gravity direction of the components themselves. Similarly, for the convenience of understanding and description, "inner, outer" refers to the inner and outer relative to the contour of each component itself, but the above orientation words are not used to limit the present application.

[0026] In order to solve the problem of affecting production efficiency caused by changing the crown strip supply frame in the prior art, the application provides a rubber material supply device and a forming machine.

[0027] As shown in Figures 1 to 5 The rubber material supply device of the embodiment includes a first material feeding device 10 and a second material feeding device 11, a first material clamping device 20 and a second material clamping device 21, a first cutting device 30 and a second cutting device 31, and a joint device 40. The first material clamping device 20 and the second material clamping device 21 clamp the head and tail of different material rolls, respectively. The first cutting device 30 and the second cutting device 31 are arranged on the downstream side of the first material clamping device 20 and the second material clamping device 21, respectively. Different rolls of rubber material are transported from the first material feeding device 10 and the second material feeding device 11 to the first cutting device 30 and the second cutting device 31 via the first material clamping device 20 and the second material clamping device 21, respectively. The first cutting device 30 and the second cutting device 31 cut the tail of the rubber material. The joint device 40 is arranged on the downstream side of the first cutting device 30 and the second cutting device 31. The rubber material is transported from the first cutting device 30 and the second cutting device 31 to the joint device 40. The joint device 40 presses the head and tail of different rubber materials together. When the rubber material of the first material feeding device 10 is consumed, the first material clamping device 20 clamps the tail of the rubber material of the first material feeding device 10, the second material clamping device 21 clamps the head of the rubber material of the second material feeding device 11, the joint device 40 presses the tail and the head together, the first cutting device 30 cuts the end of the tail, and the second material feeding device 11 continues to supply the rubber material.

[0028] As shown in Figures 1 to 5As shown, the rubber material feeding device of the embodiment provides two work stations for feeding rubber material, and the first feeding device 10 and the second feeding device 11 are used for placing the rubber material in the form of a roll. The first clamping device 20 and the second clamping device 21 are respectively connected to the first feeding device 10 and the second feeding device 11, and they respectively act on the head and tail of the different rolls. The first cutting device 30 and the second cutting device 31 are located downstream of the respective clamping devices, so that the roll material can be further conveyed to the corresponding first cutting device 30 and second cutting device 31 after passing through the corresponding first clamping device 20 and second clamping device 21 from the first feeding device 10 and the second feeding device 11, so that the cutting device cuts at the tail end of the rubber material. The joint device 40 is arranged downstream of the cutting device and is a key component for automatically switching the rubber material. When the rubber material of the first feeding device 10 is consumed, the first clamping device 20 clamps the tail of the rubber material, and the second clamping device 21 clamps the head of the second feeding device 11. Subsequently, the joint device 40 press-bonds the two parts together, so that a complete rubber material continuous feeding system is formed. The overall working process is as follows: the rubber material of the first feeding device 10 is guided and conveyed to the rear-end storage or production, and the rubber material of the second feeding device 11 is in a waiting state. When the rubber material of the first feeding device 10 is about to be consumed, the first clamping device 20 clamps the tail in advance, and the second clamping device 21 is started to fix the head of the second feeding device 11. The joint device 40 press-bonds the tail of the first cutting device 30 and the head of the second clamping device 21 to form a new continuous rubber material, and then the first cutting device 30 cuts the tail, and the rubber material drives the roll on the second feeding device 11 to move, so that the second feeding device 11 starts to feed. After the joint is completed, the roll of the first feeding device 10 can be replaced by the operator without stopping, and the new roll is guided to the head clamping position of the first clamping device 20, waiting for the next switching. When the roll of the second feeding device 11 is about to be consumed, the replacement process is the same as above, and the first feeding device 10 and the second feeding device 11 and their corresponding subsequent devices are interchanged. Through the design of the above rubber material feeding device, on the one hand, the automatic switching of the rubber material supply is realized, which not only reduces the replacement time, improves the continuity and efficiency of the production line, but also reduces the labor intensity of the operator. On the other hand, such continuous feeding not only improves the production speed, but also ensures the consistency of the product, reduces the potential errors caused by manual operation, and improves the product quality.

[0029] Optionally, the two feeding devices in this embodiment can be fixed or designed to be movable, so that operators can change the material roll without stopping the machine. The clamping device can be controlled by components such as cylinders, and the action of the clamping device can achieve precise clamping of the rubber material, ensuring that the position of the rubber material is accurate during the jointing and cutting process.

[0030] like Figure 1 As shown, in this embodiment, the first feeding device 10 and the second feeding device 11, the first clamping device 20 and the second clamping device 21, the first cutting device 30 and the second cutting device 31 are all symmetrically arranged along the longitudinal axis. Specifically, the first feeding device 10 and the second feeding device 11 are symmetrically distributed on both sides of the axis, that is, the first feeding device 10 and the second feeding device 11 are mirror images of each other along the longitudinal axis. This ensures the interchangeability of the two feeding stations. When the adhesive material at one station is exhausted, the other station can immediately start feeding without adding complex wiring or adjustments. Similarly, the first clamping device 20 and the second clamping device 21 are symmetrically arranged along the longitudinal axis and are used to clamp the head and tail of the adhesive material in the first feeding device 10 and the second feeding device 11, respectively. This symmetrical layout ensures that the head and tail of the adhesive material at the two stations can be accurately positioned during adhesive material switching, thereby improving the stability and quality of the joint. The first cutting device 30 and the second cutting device 31 are also symmetrically arranged along the longitudinal axis, located downstream of their respective clamping devices, and are responsible for cutting off the tail end of the rubber material. The symmetrical design of the cutting devices not only simplifies the structure of the device but also ensures the consistency and reliability of the cutting process, because the cutting actions and parameters of the two stations can be kept consistent, reducing product quality problems caused by process differences. This symmetrical structural design, on the one hand, enables the rubber material feeding device to achieve a balanced load distribution, reducing mechanical vibration and extending equipment lifespan. On the other hand, the symmetrical structural design ensures the uniformity of the rubber material during conveying, avoiding material deformation or equipment wear caused by excessive load on one side, thereby improving product quality.

[0031] like Figures 1 to 5As shown, in the present embodiment, the joint device 40 comprises a negative pressure suction mechanism 41 having a negative pressure end, specifically, one end of the negative pressure suction mechanism 41 is the negative pressure end, the negative pressure suction mechanism 41 can generate a stable negative pressure environment, and the negative pressure end of the negative pressure suction mechanism 41 is used to suck the material head of the rubber material. When the material head is transported to the joint device 40 through the first material clamping device 20 or the second material clamping device 21, the material head is located at the negative pressure end and is negatively adsorbed on the negative pressure end under the action of the negative pressure suction mechanism 41. That is, when the rubber material in the first material discharging device 10 or the second material discharging device 11 needs to be jointed, the first material clamping device 20 or the second material clamping device 21 will accurately transport the corresponding material head to the negative pressure end area of the joint device 40. At this time, the negative pressure suction mechanism 41 is started, and a stable vacuum loop from the negative pressure end to the vacuum generator is established and maintained through the electromagnetic valve control pneumatic vacuum generator. The material head of the rubber material is firmly adsorbed on the negative pressure end under the action of the vacuum negative pressure, which ensures the stable positioning of the material head during the jointing process and avoids the jointing failure or the jointing quality decline caused by the shaking of the material head.

[0032] Optionally, the port shape of the negative pressure end is the same as or similar to the shape of the rubber material, so that the negative pressure end can better adsorb the rubber material.

[0033] The negative pressure suction mechanism 41 of the present embodiment further comprises a vacuum air storage tank. Before the joint device 40 works, the vacuum air storage tank will pre-establish a negative pressure environment and maintain a certain pressure, so as to ensure the rapidness and efficiency of the adsorption process. The use of the vacuum air storage tank avoids the start of the vacuum generator every time the jointing is performed, reduces the consumption of compressed air energy, and also improves the response speed of the jointing process. The design of the above negative pressure suction mechanism 41 can ensure the accurate alignment of the material head of the rubber material during the jointing process on the one hand, avoid the errors in manual operation, and significantly enhance the accuracy and reliability of the jointing. On the other hand, the automatic negative pressure suction mechanism 41 avoids the positioning and fixing of the material head by manual operation, greatly shortens the time required for jointing, improves the operation efficiency of the whole rubber material feeding system, reduces the energy consumption in the production process, and reduces the production cost.

[0034] The joint device 40 of the present embodiment further comprises a joint pressing plate 42 and a joint driving member 43. The joint pressing plate 42 is the main component for performing the pressing operation, and the joint pressing plate 42 can be provided with a pair of two, and the two joint pressing plates 42 can be pressed close to each other to realize the pressing. The negative pressure end of the negative pressure suction mechanism 41 is arranged at the surface where the joint pressing plates 42 are close to each other, so that the rubber material can be negatively adsorbed. The joint driving member 43 provides power for the driving of the joint pressing plate 42, and the joint pressing plate 42 can adopt components such as air cylinders and motors.

[0035] As Figures 1 to 5As shown, in the embodiment, the first cutting device 30 and the second cutting device 31 are of the same structure, and the first cutting device 30 is taken as an example, the first cutting device 30 comprises a first cutter 32 and a second cutter 33, at least one of the first cutter 32 and the second cutter 33 is movably arranged and has a cutting position close to each other and a avoiding position away from each other, so that the positions of the two cutters can be close to each other or away from each other when the cutters move, the first cutter 32 and / or the second cutter 33 has a cutting bevel 34 for cutting rubber, so that when the two cutters are close to each other, the cutting bevels on the cutters can cooperate with each other to achieve the function of cutting rubber.

[0036] In the embodiment, the first cutter 32 is fixedly arranged, and the second cutter 33 is movably arranged, the cutting bevel 34 is arranged on the first cutter 32, and the lengths of the first cutter 32 and the second cutter 33 are arranged at an angle, and the embodiment adopts a vertical arrangement, the first cutter 32 extends longitudinally, and the second cutter 33 extends transversely and is movable transversely, so that when the second cutter 33 is in the avoiding position, a certain space is left between the first cutter 32 and the second cutter 33, so that the rubber can pass smoothly, and when the rubber needs to be cut, the second cutter 33 moves to the cutting position close to the first cutter 32, and the second cutter 33 abuts and cooperates with the cutting bevel 34 of the first cutter 32, and the angle between the cutting bevel 34 and the cutting edge of the second cutter 33 is arranged, so that the first cutter 32 and the second cutter 33 cooperate to cut the rubber, the above cutting method can cut the tail part of the rubber by the bevel when the movable cutter is close to the rubber, instead of the traditional vertical cutting, the structure of linear motion is converted into shearing action, the success rate of cutting is greatly improved, the service life of the cutter is prolonged, and the stability of the equipment is improved.

[0037] Optionally, the above-mentioned angle design can also be adjusted according to the characteristics of the rubber or different cutting requirements to ensure that the best cutting effect can be achieved. The first cutting device 30 of the embodiment further comprises a driving assembly 35, the driving assembly 35 is drivingly connected with the second cutter 33 and drives the second cutter 33 to switch between the cutting position and the avoiding position. The driving assembly 35 of the embodiment adopts a pneumatic cylinder, the cylinder rod of the pneumatic cylinder is fixedly connected with the second cutter 33, so as to realize the driving effect of the second cutter 33. Of course, the driving assembly 35 can also adopt other driving components. Since the structure of the second cutting device 31 is the same as that of the above-mentioned first cutting device 30, it will not be described again. Of course, the first cutting device 30 and the second cutting device 31 can also adopt different structures, as long as they can act respectively to achieve the corresponding cutting effect.

[0038] As shown in the drawings, Figures 1 to 5As shown, in the present embodiment, a cutting position is formed between the first cutter 32 and the second cutter 33, which serves as the accurate position for cutting the rubber material. The size of the cutting position can be designed according to the actual parameters of the rubber material and the process requirements, to ensure that the first cutter 32 and the second cutter 33 can accurately butt joint during cutting, forming a shearing force, thereby realizing efficient cutting of the rubber material. The first cutting device 30 and / or the second cutting device 31 further comprises a pressing plate assembly 36, which is located on the upstream side of the cutting position, i.e. the rubber material will pass through the pressing plate assembly 36 before flowing to the cutting position. The position is set to abut and press the rubber material through the pressing plate assembly 36 when the rubber material enters the cutting position, thereby playing a role in stabilizing the rubber material and keeping the rubber material in the cutting position, reducing the movement of the rubber material during cutting, and thereby improving the accuracy and effect of cutting.

[0039] The pressing plate assembly 36 of the present embodiment comprises an elastic compression part and a pressing plate part, which are fixedly connected. The elastic compression part can be a spring or the like. When the first material clamping device 20 or the second material clamping device 21 guides the rubber material to the corresponding cutting position, the pressing plate assembly 36 is first activated to abut the surface of the rubber material and fix it on the support surface in front of the cutting position through appropriate pressing force. This action ensures the stable position of the rubber material before cutting and guarantees the accurate execution of the cutting action. After the rubber material is pressed, the first cutter 32 remains fixed, and the second cutter 33 enters the cutting position and is controlled by the driving assembly 35 to move to the cutting position to form a shearing action with the first cutter 32 and cut the rubber material. The pressing plate assembly 36 continues to abut the rubber material during cutting to prevent the rubber material from moving and ensure the flatness of the cutting edge and the accuracy of the cutting position. After the cutting of the rubber material is completed, the second cutter 33 moves to a avoiding position, at which time the pressing plate assembly 36 also pulls back in the opposite direction of the pressing and releases the rubber material, so that the cut rubber material continues to be transported downstream. The pulling back action of the pressing plate needs to be synchronized with the avoiding action of the second cutter 33 to avoid secondary damage to the rubber material. On the one hand, the pressing plate assembly 36 exerts a stable pressure on the rubber material before cutting, reducing the displacement of the rubber material during cutting and thereby improving the accuracy of the cutting and ensuring the consistency of the rubber material edge. On the other hand, the design of the pressing plate assembly 36 can be adjusted according to the characteristics of the rubber material, increasing the adaptability and flexibility of the system.

[0040] Optionally, the material of the pressing plate assembly 36 can be a metal piece or a non-metal piece, but the design and material selection of the pressing plate assembly 36 need to consider the material, thickness and cutting speed of the corresponding rubber material to provide the best pressing force, which ensures the stability of the rubber material and avoids damaging the rubber material due to excessive pressure.

[0041] As Figure 1As shown, in this embodiment, the rubber material feeding device also includes a first detection device 50 and a second detection device 51, which are respectively installed near the first feeding device 10 and the second feeding device 11, for real-time monitoring of the rubber material remaining amount of the two feeding stations. Specifically, the detection device can adopt various sensor technologies, such as optical sensors, pressure sensors or ultrasonic sensors, etc., to adapt to different production environments and rubber material types. The first detection device 50 and the second detection device 51 of this embodiment are respectively installed in the position immediately above the first feeding device 10 and the second feeding device 11. The first detection device 50 and the second detection device 51 can accurately identify the remaining length of the rubber material roll and feed back the data to the control system in real time. When the rubber material remaining amount reaches the preset lower limit value, the detection device can send a signal to the corresponding cutting device, joint device, etc., so that the corresponding device acts to realize the automatic switching of the material roll feeding, and at the same time the detection device can trigger an alarm to prompt the operator to prepare to replace the rubber material roll, ensuring the continuity of the production process. On the one hand, through the first detection device 50 and the second detection device 51, the rubber material remaining amount is monitored in real time and the material roll is switched, reducing the production downtime and improving the overall production efficiency. On the other hand, it ensures the flattening and stability of the rubber material before entering the cutting station, avoiding uneven cutting and product quality problems caused by incomplete unfolding of the rubber material.

[0042] The rubber material feeding device of this embodiment also includes a first unwinding device 60 and a second unwinding device 61, the first unwinding device 60 is located between the first clamping device 20 and the first cutting device 30, and the second unwinding device 61 is located between the second clamping device 21 and the second cutting device 31, and respectively unwinds different rubber material rolls. The above position layout ensures that the rubber material has been fully unwound and kept stable before entering the cutting station, thereby improving the cutting accuracy and efficiency. Specifically, the unwinding device is usually composed of a series of guide rollers and driving components, which are used to guide the unwinding of the rubber material roll, facilitating cutting and subsequent processing. The design of the unwinding device needs to consider the thickness, width and elastic properties of the rubber material to ensure that the rubber material can smoothly and stably pass through the unwinding device.

[0043] As Figure 3As shown, in the present embodiment, the rubber material feeding device further comprises a joint roller device 70, which is located on the downstream side of the joint device 40, and the material head and tail after being crimped by the joint device 40 are subjected to roller pressing again via the joint roller device 70. That is, after the material head and tail of the rubber material are crimped by the joint device 40, they are subjected to roller pressing by the joint roller device 70 to ensure the tight connection and flatness at the joint. The layout of the joint roller device 70 designed in the rear makes the joint roller device 70 directly act on the rubber material after the joint, making up for the possible insufficient joint connection of the joint device 40. Specifically, the joint roller device 70 of the present embodiment mainly consists of two groups of rollers, which can be driven by a motor or controlled to move up and down by a pneumatic cylinder, so as to re-press the material head and tail. That is, after the joint device 40 completes the crimping of the material head and tail, the joint roller device 70 is started to press with appropriate pressing force. The rubber material at the joint is further pressed tightly, eliminating the possible small gap in the joint process and improving the connection strength at the joint. Optionally, the surface of the roller can be designed with special texture or coating to improve the friction with the surface of the rubber material, so as to ensure that the rubber material can be tightly pressed during roller pressing.

[0044] The joint device 40 of the present embodiment comprises left and right parts, and the left and right parts are connected to realize the pressing of the rubber material, and are separated to realize the passing of the rubber material. The left and right parts of the joint device 40 are also symmetrically arranged on both sides along the longitudinal axis.
