Description

Technical Field

[0001] This invention relates to the field of track processing technology, and in particular to an integrated automated production line and process for preforming rubber tracks. Background Technology

[0002] In the process of industrial and agricultural modernization, rubber tracks are widely used in construction machinery such as excavators and bulldozers due to their advantages such as good grip, shock absorption, and low damage to the ground. In the traditional rubber track pre-forming process, operations such as placing rubber and metal parts and transporting rubber belts to equipment often rely on manual labor, which is labor-intensive, inefficient, and makes it difficult to ensure the consistency of track products during the forming process.

[0003] Chinese patent CN114311684B discloses a track preforming production line, including a track metal part feeding mechanism, a track metal part discharging mechanism, a first conveying mechanism, a lower rubber belt feeding mechanism, an upper rubber belt feeding mechanism, a track metal part loading mechanism, and a pressing mechanism. The track metal part discharging mechanism includes a discharging rack and a discharging assembly. The discharging rack is located on one side of the track metal part feeding mechanism and has a discharging trough. The discharging assembly can transport the track metal parts provided by the track metal part feeding mechanism to the first discharging trough in front and transport the track metal parts in the previous discharging trough from front to back to the next discharging trough. The first conveying mechanism has a metal part loading station and a pressing station. The track metal part loading mechanism is used to transport the track metal parts on the discharging trough to the upper part of the lower rubber belt located at the metal part loading station. The pressing mechanism is used to press the lower rubber belt, track metal parts, and upper rubber belt located at the pressing station together.

[0004] However, this technical solution has the following shortcomings: the batching production line and the preforming production line are not integrated, and manual transfer to other workstations is required to continue subsequent production steps. This can lead to human error and cannot guarantee product consistency, which also reduces production efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an integrated automated production line for rubber track preforming. By setting up a preforming module, a batching module, and a palletizing module, the batching production line and the preforming process in rubber track production are modularly connected, resulting in a high degree of automation, improved production efficiency, and guaranteed product consistency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated automated production line for preforming rubber tracks, comprising a preforming module, a batching module, and a palletizing module; the preforming module is used to automatically adjust the spacing of the iron teeth, cut and arrange the base rubber and top rubber, and press the three together into a pre-finished product; the batching module is connected to the preforming module, weighs and measures the pre-finished product and the top rubber respectively, calculates the replenishment weight, and adds adjusting rubber; the palletizing module is connected to the batching module, and matches and pallets a set of the pre-finished products and their corresponding rubber materials.

[0007] As an improvement, the preforming module includes a first unloading station and a tooth spacing adjustment station; the first unloading station unwinds the base adhesive and top adhesive, and then cuts them after conveying them to the placement area; the tooth spacing adjustment station is equipped with a spacing adjustment mechanism to transfer the teeth placed on the input end to the output end in sequence, while maintaining a certain distance.

[0008] As an improvement, a transfer mechanism is provided between the first feeding station and the tooth spacing adjustment station; the transfer mechanism uses magnetic attraction to synchronously transfer a set of adjusted teeth to the placement area and place them on the base adhesive.

[0009] As an improvement, the preforming module also includes a pressing station, which is equipped with a flexible mold; the flexible mold presses the conveyed iron teeth, bottom adhesive and top adhesive together, and then automatically demolds and conveys them to the material dispensing module.

[0010] As an improvement, the ingredient dispensing module includes a second feeding station and a weighing station; the second feeding station unwinds and cuts the top adhesive and adjusting adhesive; the weighing station receives the pre-finished product on one side and weighs it, and receives the top adhesive on the other side, calculates its value, and then adds the adjusting adhesive.

[0011] As an improvement, a weighing sensor is installed at the bottom of the conveyor belt of the weighing station.

[0012] As an improvement, the palletizing module includes a lifting station, which is equipped with a lifting mechanism to lift and transfer the material transported from the previous station.

[0013] As an improvement, the palletizing module also includes a transfer station, which is equipped with several transfer vehicles; the transfer vehicles are equipped with several even-numbered placement layers.

[0014] As an improvement, a conveyor belt is provided at the bottom of the transfer vehicle.

[0015] As an improvement, vision sensors are installed in the preforming module, the batching module, and the palletizing module.

[0016] This invention also provides an integrated automated production process for rubber track preforming, comprising the following steps: Equally spaced iron teeth: The iron teeth on the preset line are transferred one by one to the production line via the loading table. The production line transmits them at equal intervals, arranging several iron teeth at equal intervals. During the unwinding process at the first unwinding station, the base adhesive is conveyed to the placement area to a set length and then cut by a cutter. The transfer mechanism transfers a set of pre-adjusted iron teeth onto the base rubber in one go, while simultaneously weighing and recording the weight of the set of iron teeth; As the base adhesive and iron teeth are transferred to the pressing station, the top adhesive is simultaneously laid on the iron teeth and conveyed forward. Once the set length is reached, the top adhesive is cut by a cutter. The flexible mold presses together the delivered iron teeth, bottom adhesive, and top adhesive, and then automatically demolds and delivers them to the batching module II; The second feeding station adds adjusting adhesive based on the weighing results and conveys it to the subsequent station along with the top adhesive. The lifting station transfers a set of adhesive materials with matching weight. The set of adhesive materials with matching weight is then stacked on adjacent layers on the transport vehicle.

[0017] The beneficial effects of this invention are as follows: (1) This invention integrates and connects the various links in the production process of rubber tracks to form relatively independent yet closely connected modules, making the production process smoother, reducing the waiting time between processes and the material handling distance, and improving the overall production efficiency by having multiple modules work together.

[0018] (2) By setting up a tooth spacing adjustment station, the present invention arranges the teeth sequentially and maintains a certain distance, and transfers them to the output end together, replacing manual arrangement and spacing adjustment operations. This method is safe, fast, and improves production rate.

[0019] (3) By setting up a batching module, the present invention weighs and measures the pre-finished products and the top adhesive separately, and adds the corresponding weight of adjusting adhesive after calculation, so as to achieve the weight matching of a set of pre-finished products and top adhesive, thereby ensuring the consistency of product quality.

[0020] (4) By setting up a stacking module, the present invention stacks a set of corresponding pre-finished products and surface adhesives to match the subsequent vulcanization process, improves the feeding speed, and also ensures that the weight of any track after different groups of tracks are formed meets the process requirements.

[0021] In summary, the present invention has the advantages of high production efficiency, high degree of automation, and good product consistency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] Example 1 like Figures 1 to 18 As shown, this embodiment provides an integrated automated production line for preforming rubber tracks, including a preforming module I, a batching module II, and a palletizing module III. The preforming module I is used to automatically adjust the spacing of the iron teeth 11, cut and arrange the bottom rubber 12 and top rubber 13, and press the three together to form a pre-finished product 1. The batching module II is connected to the preforming module I, weighs and measures the pre-finished product 1 and the top rubber 14 respectively, calculates the replenishment weight, and adds adjusting rubber 15. The palletizing module III is connected to the batching module II, and matches and pallets a set of pre-finished products 1 and their corresponding rubber materials.

[0026] It is worth mentioning that by integrating and connecting various stages in the rubber track production process, relatively independent yet closely connected modules are formed, making the production process smoother, reducing waiting time between processes and material handling distances, and enabling multiple modules to work together to improve overall production efficiency.

[0027] The preforming module I includes a first unloading station 2 and a tooth spacing adjustment station 3. The first unloading station 2 unwinds the base adhesive 12 and top adhesive 13, and then cuts them after conveying them to the placement area 21. The tooth spacing adjustment station 3 is equipped with a spacing adjustment mechanism 31, which sequentially transfers the tooth 11 placed on the input end 32 to the output end 33 while maintaining a certain distance.

[0028] Specifically, the adjusting mechanism 31 includes a platform 311 and a power component 312. The platform 311 carries the iron teeth 11 arranged on the input end 32, and the power component 312 moves the platform 311 downward and transports the iron teeth 11 to the output end 33. In some preferred embodiments, the power component 312 is a cylinder. Cylinders have the advantages of simple control, relatively low procurement cost, and long service life, thus saving economic costs.

[0029] Meanwhile, the jump distance mechanism 31 also includes a preset line 313, which is connected to a production line 314. A transfer component 315 is provided between the preset line 313 and the production line 314 to transfer the closely arranged iron teeth 11 on the preset line 313 to the production line 314 in sequence, while maintaining a certain distance. The distance is adjustable, which avoids the need for operators to place the iron teeth 11 one by one into the mold, improves work efficiency, and increases safety.

[0030] In this embodiment, it should be noted that the production line 314 is a step-by-step transmission. According to the different requirements of the tooth spacing 11, the production line 314 moves a certain distance in steps and then stops. The tooth 11 on the preset line 313 is transferred to the production line 314 through the transfer component 315. The production line 314 continues to move forward in steps for a certain distance. The tooth 11 is transferred repeatedly by the transfer component 315 to realize the automatic adjustment of the tooth spacing 11.

[0031] In addition, the preset line 313 can be a double-speed transmission line, so that all the iron teeth 11 are concentrated near one end of the production line 314.

[0032] In this embodiment, the production line 314 and the preset line 313 are staggered in height.

[0033] In this embodiment, the preset line 313 is higher than the production line 314. The platform 311 moves downward when transferring the iron teeth 11. Compared with lifting the iron teeth 11 upward, it is supported by gravity and consumes less energy.

[0034] In this embodiment, the transfer assembly 315 includes a base 3151, which is fixedly connected to the bottom of the preset line 313; guide seats 3152 are symmetrically arranged on both sides of the base 3151; a guide rod 3153 is slidably arranged in the guide seat 3152; a connecting seat 3154 is provided on the top of the guide rod 3153; the platform 311 is mounted on the connecting seat 3154; and a power component 312 is also provided on the base 3151, preferably a cylinder, the output end of which is connected to the guide rod 3153.

[0035] In this embodiment, the platform 311 is symmetrically arranged on both sides of the base 3151, which can transfer the iron tooth 11 from the preset line 313 to the production line 314 without affecting the transmission of the iron tooth 11 on the preset line 313 and the production line 314; the guide seat 3152 can limit and guide the guide rod 3153 to ensure that the platform 311 remains stable when transferring the iron tooth 11.

[0036] In this embodiment, the bottom of the guide rod 3153 penetrates the base 3151 and is connected to the guide rods 3153 on both sides by the connector 3155.

[0037] Specifically, the penetrating base 3151 allows the guide rod 3153 to have more room to move, which can be better adjusted according to the height difference between the two production lines to meet the transmission of iron teeth 11 at different heights.

[0038] It is worth mentioning that the connector 3155 maintains the consistency of the lifting of the two side platforms 311, and ensures the stability of the iron teeth 11 during the transfer process under synchronous operation. This avoids the need for manual readjustment due to uneven arrangement of the iron teeth 11 on both sides during the transfer, and further improves production efficiency.

[0039] In this embodiment, a retaining edge 316 is provided at one end of the platform 311 near the production line 314.

[0040] In this embodiment, the position of the iron tooth 11 before it is transferred from the preset line 313 to the production line 314 is used to ensure that the position of the iron tooth 11 on the production line 314 after the transfer remains consistent, thereby improving the adjustment accuracy of the iron tooth 11 spacing and ensuring safety during the transfer process, preventing the iron tooth 11 from falling off and causing damage.

[0041] In this embodiment, the bottom of the platform 311 extends downward to provide a mounting block 317, and the connecting seat 3154 is provided with a sliding groove 3156 that is shaped to conform to the mounting block 317.

[0042] In this embodiment, to ensure that the platform 311 is positioned by the slide 3156 during assembly and can be installed quickly, the distance between the two platforms 311 can be adjusted according to the length of different iron teeth 11, thereby improving the applicability of the equipment.

[0043] In this embodiment, a limiting member 318 is provided above the stage 311, and the distance between the limiting member 318 and the stage 311 is adjustable.

[0044] It should be noted that the limiting member 318 can prevent the next iron tooth 11 from continuing to move onto the platform 311 after the previous iron tooth 11 has moved onto the platform 311. The structure is simple and the manufacturing cost is low. Moreover, the distance between the limiting member 318 and the surface of the platform 311 can be adjusted according to the specifications of the iron tooth 11 being produced, so as to adapt to more production requirements.

[0045] In this embodiment, a sensor 319 is provided on the transfer component 315, and the sensor 319 is located on one side of the limiting member 318.

[0046] In this embodiment, the sensor 319 can sense whether the iron tooth 11 is completely against the stop edge 316 during the transfer process, that is, detect whether the iron tooth 11 has been transferred to the correct position, so that the transfer component 315 can accurately transfer the iron tooth 11 and avoid the phenomenon of missing teeth caused by the lack of iron tooth 11 in the downward transfer of the platform 311.

[0047] In this embodiment, the working steps of the adjusting mechanism 31 are as follows: the production personnel place the iron teeth 11 closely on the preset line 313. The iron teeth 11 move forward with the preset line 313. When the first set of iron teeth 11 moves to the platform 311, the cylinder push rod moves downward and drives the guide rod 3153 downward through the connector 3155. The platform 311 carries the iron teeth 11 to the production line 314. The next set of iron teeth 11 is blocked by the limiting member 318 and stops on the preset line 313. After the platform 311 is lowered to the position, the iron teeth 11 continue to move forward on the production line 314. The platform 311 rises and moves the next iron tooth 11. This process is repeated to maintain an equal spacing.

[0048] In this embodiment, a transfer mechanism 34 is provided between the first feeding station 2 and the tooth spacing adjustment station 3; the transfer mechanism 34 uses magnetic attraction to synchronously transfer a set of adjusted tooth 11 to the placement area 21 and place it on the base adhesive 12.

[0049] In this embodiment, the transfer mechanism 34 includes: a support base 341, a movable base 342 slidably connected to the support base 341, a first driving member 343 disposed on one side of the support base 341 to provide power for the movement of the movable base 342, a magnetic suction member 344 disposed below the movable base 342, a lifting member 345 disposed on the movable base 342 and fixedly connected to the magnetic suction member 344 for controlling the up-and-down reciprocating movement of the magnetic suction member 344, and a second driving member 346 disposed at one end of the lifting member 345 and providing power thereto. The mechanism utilizes the lifting member 345, the movable base 342, the first driving member 343, and the second driving member 346. The magnetic suction component 344 can move the iron teeth 11 up, down, left, and right to synchronously transfer a set of adjusted iron teeth 11 to the placement area 21 and place them on the base adhesive 12. The first driving component 343 and the second driving component 346 can both be driven by motors. The lifting component 345 can be a ball screw mechanism, which is easy to control and can quickly perform magnetic suction operations. The shape of the magnetic suction component 344 is adapted to a set of iron teeth 11. Specifically, its bottom can directly use magnetic force to hold all the iron teeth 11, so that the iron teeth 11 will not fall off, and all the iron teeth 11 in the set can be transferred to the placement area 21. The whole process is simple to operate, convenient to use, and highly efficient.

[0050] In this embodiment, the first unloading station 2 is generally controlled by an unwinding structure 22, which specifically includes: a first support frame 221; a first conveyor belt 222 disposed above the first support frame 221 for conveying the top adhesive 13; a first cutter 223 disposed directly above the first conveyor belt 222; a second conveyor belt 224 disposed adjacent to the first support frame 221 and installed below the first conveyor belt 222 for conveying the base adhesive 12; a second cutter 225 disposed on the second conveyor belt 224; a first unwinding roller 226 disposed inside the first support frame 221; and a third drive member 227 disposed on one side of the first unwinding roller 226 and fixedly connected to the first support frame 221. The second support frame 228, located adjacent to the first support frame 221, the second unwinding roller 229 located inside the second support frame 228, and the fourth drive unit 2281 located on one side of the second support frame 228 for controlling the rotation of the second unwinding roller 229, can control the required length of the rubber material through two cutters to suit iron teeth 11 of different sizes; the second conveyor belt 224 is installed above the placement area 21; the first conveyor belt 222 and the second conveyor belt 224 are placed at an acute angle, and their approach points correspond exactly to the upper and lower ends of the iron teeth 11; the third drive unit 227 and the fourth drive unit 2281 are both preferably servo motors to control the rotation speed of the two unwinding rollers and ensure conveying efficiency.

[0051] In this embodiment, during the unwinding process, the top adhesive 13 is located above the bottom adhesive 12. After being conveyed to the placement area 21 to a set length, it is cut by a cutter. At this time, both are still on their respective conveyor belts. The transfer mechanism 34 magnetically transfers a set of pre-adjusted iron teeth 11 to the bottom adhesive 12 in one go. During the process of conveying to the pressing station 4, the top adhesive 13 covers the iron teeth 11 and is transferred together.

[0052] In this embodiment, the preforming module I further includes a pressing station 4, which is equipped with a flexible mold. The flexible mold presses the conveyed iron teeth 11, bottom adhesive 12 and top adhesive 13 together, and then automatically demolds and conveys them to the batching module II.

[0053] Understandably, flexible molds pre-form materials, and the flexible deformation of the mold enables product pressing and automatic demolding. At the same time, it can also eliminate the need to change or adjust the mold when molding different product models, saving mold change time and further improving production efficiency.

[0054] Of course, vision sensors are installed in the preforming module I, the batching module II, and the palletizing module III.

[0055] In addition, the advantage of this setup is that it allows for real-time monitoring and feedback of the specific position of the iron teeth 11; the position of the top rubber 13; and the bonding of the surface rubber and the adjusted rubber after cutting, ensuring the consistency of each rubber track product and improving the quality of the same batch of products.

[0056] Example 2 Components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as those in Embodiment 1. The difference between Embodiment 2 and Embodiment 1 is that: [e.g., ...] Figures 10 to 18 As shown, the batching module II of this integrated rubber track preforming automated production line includes a second unloading station 5 and a weighing station 6; the second unloading station 5 unwinds and cuts the surface adhesive 14 and the adjusting adhesive 15; the weighing station 6 receives the pre-finished product 1 on one side and weighs it, and receives the surface adhesive 14 on the other side, calculates it, and then adds the adjusting adhesive 15; the structure of the second unloading station 5 is similar to that of the first unloading station 2, the difference being the different conveying materials.

[0057] It should be noted that the adjusting adhesive 15 is located above the top adhesive 14. Based on the weighing and measurement results, the top adhesive 14 and the adjusting adhesive 15 are conveyed to the subsequent station. The adjusting adhesive 15 is relatively thin, and its length can be used to obtain a more accurate quality. It should be shorter than the length of the top adhesive 14. The pre-finished products conveyed to the batching module II are located on one side of the second feeding station 5.

[0058] The weighing station 6 is equipped with a weighing sensor 61 at the bottom of the conveyor belt.

[0059] It should be noted that the calculated weight includes the weight of the iron teeth 11. The iron teeth are weighed during the placement process at the front end, and the actual total weight of the rubber material is obtained by combining the weight of the weighing station 6. The weighing sensor 14 can meet the production needs of multiple product models, and the required process parameters can be set through the control panel.

[0060] In this embodiment, the weighing station 6 further includes a batching section 62, which is connected to a discharge section 63. The batching section 62 conveys the pre-finished product 1 and the top adhesive 14. The batching section 62 weighs and measures the pre-finished product 1 and the top adhesive 14 respectively, calculates the replenishment weight, and adds adjusting glue 15 to the top adhesive 14.

[0061] In this embodiment, the batching section 62 includes: a first metering station 621, a second metering station 622 is provided on one side of the first metering station 621, and a replenishing station 623 is provided above the second metering station 622; the first metering station 621 conveys pre-finished product 1, the second metering station 622 conveys surface adhesive 14, and the replenishing station 623 conveys adjusting adhesive 15.

[0062] In this embodiment, different workstations can operate synchronously, conveying the pre-finished product 1 and the top adhesive 14 to the subsequent workstations. When the set length is reached, the adhesive is cut.

[0063] In addition, since the adjusting adhesive 15 is relatively thin and does not affect the final product, it can be shorter than the length of the top adhesive 14, and there are no special positional requirements.

[0064] In this embodiment, the weighing sensor 61 is respectively installed at the bottom of the first metering station 621 and the second metering station 622.

[0065] It is worth mentioning that the weighing sensor 61 is connected between the conveyor belt and the bottom support. The weighing sensor 61 feeds back the data measured at the two stations to the control panel to calculate the weight of the replenished material. For different models of rubber track pre-forming, there is no need to adjust the entire equipment. You only need to modify the corresponding parameters through the control panel.

[0066] In this embodiment, the weight measured by the first metering station 621 includes the weight of the iron teeth 11. By combining the weight measurement of the iron teeth 11 during the placement process of the front iron teeth 11, the actual total weight of the adhesive material at the first metering station 621 is obtained.

[0067] In this embodiment, the feeding station 623 is inclined, with its lowest point located at the output end of the second metering station 622.

[0068] In some embodiments, since the adjusting adhesive 15 has no special positional requirements, the replenishing station 623 can be set above other positions of the second metering station 622, preferably at the output end of the second metering station 622. This ensures that when adding a longer adjusting adhesive 15, there is enough length of top adhesive 14 to place. The inclined setting also helps the adjusting adhesive 15 to be supported by gravity and smoothly conveyed downwards to the top adhesive 14.

[0069] In this embodiment, the input end of the feeding station 623 is provided with a third cutter 624.

[0070] It should be noted that the third cutter 624 cuts the adjusting adhesive 15 based on the feedback data obtained from the control panel. The adjusting adhesive 15 is relatively thin, and the weight of a certain length of adjusting adhesive 15 can be precisely controlled according to the length.

[0071] In this embodiment, the palletizing module III includes a lifting station 7 and a transfer station 8. The discharge section 63 transfers the pre-finished product 1 and the corresponding replenished adhesive 14 to the transfer station 8.

[0072] In this embodiment, the lifting station 7 is equipped with a lifting mechanism 71 to lift and transfer the material conveyed from the previous station. The discharge section 63 is equipped with a mounting frame 631, and the top of the mounting frame 631 is equipped with the lifting mechanism 71. The lifting mechanism 71 is connected to a conveyor frame 72.

[0073] It should be noted that the lifting mechanism 71 preferably uses sprocket drive to drive the conveyor frame 72, which receives the products from the previous process, to lift and move. This allows the calculated and matched set of adhesive materials to be conveyed to the corresponding positions, so as to realize the alternating stacking of pre-finished products 1 and top adhesive 14. This method has a high degree of automation and does not require manual operation, thus freeing up labor.

[0074] In this embodiment, a limiting wheel 73 is rotatably provided at the connection between the conveyor frame 72 and the lifting mechanism 71; a limiting frame 74 corresponding to the limiting wheel 73 is provided on the mounting frame 631.

[0075] In this embodiment, the limiting wheel 73 cooperates with the limiting frame 74, and the limiting wheel 73 always rolls on the limiting frame 74. Under the drive of the limiting wheel 73, the conveyor frame 72 connected to the limiting wheel 73 ensures that the conveyor frame 72 as a whole remains horizontal and stable during the movement. In this embodiment, the transfer station 8 is provided with a plurality of transfer vehicles 81, and the transfer vehicles 81 are provided with a plurality of placement layers 811.

[0076] It is worth mentioning that the pre-finished products 1 and the surface rubber 14 placed on the upper and lower sides of the placement layer 811 are grouped together to match the subsequent vulcanization process, thereby improving the feeding efficiency of the subsequent vulcanization molding. At the same time, the total weight of the rubber material of the two corresponding layers is matched with the total weight of the track after molding, so as to minimize the difference in the total weight of the rubber material of any two adjacent groups. Ideally, the difference can be close to zero, ensuring that the weight of any track after different groups of track molding meets the process requirements.

[0077] In this embodiment, each transport vehicle 81 has two adjacent placement layers 811, which respectively place the pre-finished product 1 and the adjusted surface adhesive 14. They are stacked alternately in a one-to-one correspondence, which matches an even number of layers, ensuring that the same set of adhesive materials corresponds and also facilitating the transfer of subsequent vulcanization processes.

[0078] In this embodiment, the number of placement layers 811 is even. The advantage of this setting is that the pre-finished product 1 and the adhesive 14 can be stacked alternately in corresponding layers. If one of the two is placed in an odd-numbered placement layer 811, it is easy to cause incorrect matching problems in subsequent production.

[0079] Of course, the bottom of the transfer vehicle 81 is provided with a conveyor belt 82, and the transfer vehicle 81 is located on the conveyor belt 67 and is driven by the conveyor belt.

[0080] In addition, the conveyor belt 82 can automatically switch the position of the transfer car 81. After completing the stacking of several sets of pre-finished products 1 on one side, it can be transferred to the other side for the corresponding matching adhesive 14. That is, the pre-finished products 1 and adhesive 14 transferred from the two sets of lifting stations 7 are loaded accordingly. There is no need for manual operation and repeated back-and-forth switching of positions, which further saves stacking time, improves production efficiency, and avoids matching errors after long-term manual labor.

[0081] Example 3 The components that are the same as or corresponding to those in Embodiment 1 are marked with the same reference numerals as those in Embodiment 1. The difference between Embodiment 3 and Embodiment 1 is that: an integrated rubber track preforming automated production process, during the unwinding process at the first unwinding station 2, the top rubber 13 and bottom rubber 12 are conveyed to the placement area 21 to a set length and then cut by a cutter. The transfer mechanism 34 magnetically transfers a set of pre-adjusted iron teeth 11 onto the bottom rubber 12. During the conveying process to the pressing station 4, the top rubber 13 covers the iron teeth 11 and is transferred together. During the transfer of the iron teeth 11, the weight is measured. The flexible mold presses the conveyed iron teeth 11, bottom rubber 12 and top rubber 13 together, and then automatically demolds and conveys them to the batching module II. The second unwinding station 5 adds adjusting rubber 15 according to the weighing result and conveys it to the subsequent station together with the top rubber 14. The lifting station 7 transfers a set of matching rubber materials and completes one-to-one layered alternating stacking on the transport vehicle 81.

[0082] In the batching section 62, the first metering station 11 weighs the pre-finished product 1, and the weighing sensor 61 records and feeds the data back to the control panel. The pre-finished product 1 is transferred to the discharge section 63. The lifting mechanism 71 drives the conveyor frame 72 to send the pre-finished product 1 to the placement layer 411 on the first floor of the transfer car 81 in the transfer station 8. The subsequent pre-finished products 1 are sent to the third floor, the fifth floor, and so on. After the placement layer 411 with odd-numbered floors is full, the conveyor belt 82 transfers the car 81 to the other side of the transfer station 8.

[0083] In addition, the second metering station 12 weighs the surface adhesive 14. After receiving feedback from the weighing sensor 14, the control panel calculates the weight of the corresponding pre-finished product 1 and controls the third cutter 624 to cut into the appropriate adjusting adhesive 15 to supplement the surface adhesive 14. The surface adhesive 14 flows to the discharge section 63. The lifting mechanism 71 drives the conveyor frame 72 to send the surface adhesive 14 to the second layer 411 of the transfer car 81 in the transfer station 8. The subsequent surface adhesive 14 is sent to the fourth layer, the sixth layer, and so on, and is stacked alternately with the corresponding pre-finished product 1.

[0084] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
