Technical Field

[0001] The utility model relates to the technical field of shoe tree production, in particular to a production device for paper sheet shoe trees. Background Art

[0002] A shoe tree is a tool placed inside a shoe to maintain the shoe shape and protect the shoe from deformation, with a shape that fits the toe or the shoe body. Existing shoe tree materials are diverse, and pulp is widely used due to its low cost and degradability. However, using pulp as the raw material for shoe tree production has many defects, as follows:

[0003] In terms of production process: The production of pulp shoe trees usually requires multiple processes such as pulping, thermoforming, drying, hot pressing, and cutting, with a relatively complex process. In the pulping process, recycled paper and other raw materials need to be beaten into pulp together, and a beating device is often used in this process. The beating takes a long time and has low efficiency, affecting the overall production efficiency;

[0004] In terms of cost: Although the cost of pulp raw materials themselves is low, due to their complex production process and the need to add a large amount of auxiliary materials such as waterproofing agents and hardening agents during production to improve the performance of pulp shoe trees, this increases the production cost to a certain extent.

[0031] The present utility model will be further described below in conjunction with the accompanying drawings:

[0032] Referring to the attached drawings: The production equipment for this paper shoe tree includes a frame 1, which has a high-order workbench surface 11 and a low-order workbench surface 12. The high-order workbench surface 11 is used to set up a feeding frame 2, a material taking mechanism, a guiding track 5, a feeding mechanism, and a gluing mechanism. The low-order workbench surface 12 is used to set up a forming mechanism, a limiting mechanism, and a discharging and material taking mechanism. The principle of the present utility model is that the raw material paper is placed in the feeding frame 2 arranged on the frame 1 in a vertically stacked form. There are multiple feeding frames 2 arranged horizontally in sequence. According to the actual production situation, the placement of the raw material paper is completed manually, so that there are several sheets of raw material paper in each feeding frame 2 that can maintain multiple processing operations. The raw material paper in the feeding frame 2 is separated from the feeding frame 2 through the material taking mechanism. A guiding track 5 located below the feeding frame 2 is arranged between the feeding frame 2 corresponding to the material taking mechanism and the forming mechanism arranged on the frame 1. And each guiding track 5 is equipped with a corresponding feeding mechanism. The feeding mechanism runs on the guiding track 5 to transport the raw material paper taken by the material taking mechanism to the guiding track 5 to the forming mechanism. The guiding track 5 provided guiding track is divided into a pre-conveying stop starting end 511, a mid-conveying stop middle end 512, and a post-conveying stop ending end 513. Three position endpoints are set, and the operation of the material taking mechanism, the feeding mechanism, and the forming mechanism is controlled by the raw material paper falling at the three position endpoints. A reserved distance is left between the lowermost raw material paper and the pre-conveying stop starting end 511. Detect the initial position of the material taking port of the material taking mechanism, and perform the following actions according to the orientation of the material taking port of the material taking mechanism:

[0033] If it is detected that the material taking port of the material taking mechanism is within the reserved distance, drive the material taking port of the material taking mechanism to reset to the pre-conveying stop starting end 511. After the material taking port of the material taking mechanism is reset, it moves up a distance equal to the reserved distance to reach below the lowermost raw material paper;

[0034] After it is detected that the material taking port of the material taking mechanism is below the raw material paper, drive the material taking port of the material taking mechanism to perform a material taking action. After the material taking is completed, it descends to the pre-conveying stop starting end 511;

[0035] When it is detected that the raw material paper has fallen onto the guiding track 5, drive the feeding mechanism to run along the guiding track to transport the raw material paper to the mid-conveying stop middle end 512;

[0036] When it is detected that the raw material paper reaches the mid-conveying stop middle end 512, drive the feeding mechanism to move back to the pre-conveying stop starting end 511, and the previously conveyed raw material paper stays at the mid-conveying stop middle end 512;

[0037] When it is detected that the feeding mechanism has been reset in place, the material taking mechanism repeats the material taking action, and the gluing mechanism synchronously completes the gluing action;

[0038] When it is detected that the material taking mechanism has completed repeated material taking actions and the new raw material paper arrives at the starting end 511 before conveying and stays, the feeding mechanism is driven to run along the guiding track to convey the new raw material paper to the intermediate end 512 during conveying and stay. At the same time, the raw material paper that originally stayed at the intermediate end 512 during conveying is also conveyed to the end 513 after conveying and stays;

[0039] When it is detected that the raw material paper arrives at the end 513 after conveying and stays, the forming mechanism is driven to complete the forming action, that is, the raw material paper is formed into a shoe tree;

[0040] When it is detected that the forming action is completed, the forming mechanism resets to the initial position;

[0041] The position of the material taking mechanism is directly docked with the starting end 511 before conveying and stays, and the feeding operation can be directly carried out. That is, the starting end 511 before conveying and stays is used as the preparatory operation position. When the material taking mechanism confirms the execution of the material taking action, the material taking mechanism moves upward. The material taking mechanism fits with the raw material paper at the bottommost position to realize material taking. After the material taking is completed, when the material taking mechanism moves downward and resets to the starting end 511 before conveying and stays, the taken raw material paper can stay on the starting end 511 before conveying and stays, which also means that the raw material paper stays on the guiding track 5.

[0042] The feeding stroke of the feeding mechanism is fixed, and the moving distance is only the distance from the starting end 511 before conveying and stays to the intermediate end 512 during conveying and stays. Such a method is based on the setting that the feeding mechanism is a two-stage structure. That is, when the raw material paper arrives at the intermediate end 512 during conveying and stays, the intermediate end 512 during conveying and stays is the execution point of the new action. That is, the feeding mechanism for executing the conveying of the paper moves back to the starting end 511 before conveying and stays. After arriving, the material taking mechanism takes a new raw material paper to the starting end 511 before conveying and stays, and then continues to push the new raw material paper to the intermediate end 512 during conveying and stays. At this time, the feeding mechanism can also push the raw material paper that originally stayed at the intermediate end 512 during conveying and stays to move towards the end 513 after conveying and stays. This can reduce the moving stroke of the feeding mechanism, which is equivalent to reducing the intermediate execution time and improving the efficiency.

[0043] When forming the shoe tree, the position limiting mechanism is also started. The limiting mechanism is arranged at the discharging end of the forming mechanism. When it is detected that the forming mechanism does not execute the forming action, the limiting mechanism is started to close, so that the limiting mechanism blocks at the discharging end of the forming mechanism; when it is detected that the forming mechanism completes the forming action, the limiting mechanism is started to open, and the limiting mechanism no longer blocks at the discharging end of the forming mechanism. The limiting mechanism starts the blocking action when the forming mechanism executes the forming action, which can prevent the raw material paper from separating from the forming mechanism and can well limit the raw material paper in the forming mechanism.

[0044] After the formed shoe tree is completed, the discharging and material taking mechanism is started at the same time;

[0045] Detect the horizontal distance and vertical distance between the discharging and material taking mechanism and the shoe tree, and drive the discharging and material taking mechanism to move to the preset material taking position;

[0046] When it is detected that the discharging and material taking mechanism reaches the position where the shoe tree is located, drive the discharging and material taking mechanism to perform the material taking action;

[0047] After it is detected that the discharging and material taking mechanism has taken the shoe tree, drive the discharging and material taking mechanism to reset to the initial position, and make the shoe tree fall onto the conveyor belt to be sent to the designated collection position through the conveyor belt. The finished shoe tree is taken out from the forming mechanism by the discharging and material taking mechanism and sent to the conveyor belt. Here, the position limiting mechanism is also an execution prompt element, that is, when the position limiting mechanism makes a blocking action, the discharging and material taking mechanism does not start, and when the position limiting mechanism cancels the blocking action, the discharging and material taking mechanism starts, so that there will be no interference and safe production is ensured.

[0048] There are multiple material placing frames 2 arranged horizontally in sequence. It includes four positioning columns 21 that form a placing space. The upper end of the positioning column 21 has a bending section 211 that enlarges the placing space, the lower end has a positioning section 212, and the middle and lower part has an adjusting rod 213 for adjusting the placing space. A first mounting frame 111 is arranged on the high-order workbench surface 11, and the adjusting rod 213 is movably arranged on the first mounting frame 111. Such a setting enables the equipment to have multiple synchronous formations, and the material placing frame 2 can be adjusted according to the cross-sectional size of the raw material paper so that the size of its placing space matches the cross-sectional size of the raw material paper. This also enables the equipment to be applicable to processing shoe trees that match different shoe sizes. The adjustment of the material placing frame 2 is realized through the adjusting rod 213. The adjusting rod 213 cooperates with the bolts arranged on the first mounting frame 111 through the chutes provided on itself, so as to realize the adjustment movement of the adjusting rod 213 and also realize the adjustment of the size of the placing space. The bending section 211 is used to increase the size of the placing space at the entrance end of the material placing frame 2, that is, the size of the placing space at the entrance end is larger than the placing space formed by the positioning column 21, so as to avoid interference when placing the raw material paper. The positioning section 212 is used to limit the raw material paper, that is, when the material taking mechanism does not perform the material taking action, the raw material paper can be limited within the placing space of the material placing frame 2 through the positioning section 212, and the positioning section 212 is a threaded structure, so that the pitch formed by the threaded structure can be used as multiple limiting positions. When the material taking mechanism takes out the raw material paper and accidentally takes out several more sheets, the redundant raw material paper can be stopped within the corresponding limiting positions by using the limiting positions to ensure that only one raw material paper is sent to the guiding track 5 each time.

[0049] The material taking mechanism includes a first mounting plate 31, two lifting components 32, and a material taking suction nozzle group 33 that matches the quantity and position of the material discharging frames 2. The outer shaft sleeve 321 of the lifting component 32 is installed at the lower end of the first mounting plate 31. While the lifting rod 322 is movably connected to the outer shaft sleeve 321, its upper end is installed at the lower end of the high-order workbench surface 11. The material taking suction nozzle group 33 is installed on the first mounting plate 31, and each material taking suction nozzle group 33 has two material taking suction nozzles 331. The first mounting plate 31 serves the function of installation and connection, that is, it is used to connect the lifting component 32 and the material taking suction nozzle group 33 at the same time, and the length of the first mounting plate 31 is adapted to the total lateral width of the equipment. Then the quantity of the set material taking suction nozzle groups 33 can meet the usage quantity of the material discharging frames 2. Then when taking materials, the raw material papers located in different material discharging frames 2 can be taken simultaneously, thereby realizing the working mode of one machine with multiple operations. The upper end of the material taking suction nozzle 331 acts on the raw material paper, and materials are taken through the way of negative pressure suction. The lower end is externally connected to a negative pressure device. The lifting rod 322 of the lifting component 32 is installed at the lower end of the high-order workbench surface 11 to keep itself at the corresponding usage height. And the outer shaft sleeve 321 also keeps the first mounting plate 31 at the corresponding height position through the connection with the first mounting plate 31, and also makes the material taking suction nozzle 331 close to the material discharging frame 2. In this way, when the outer shaft sleeve 321 moves, the material taking suction nozzle 331 arranged on the first mounting plate 31 can quickly reach below the raw material paper, shortening the moving distance and improving the material taking efficiency.

[0050] The guiding rail 5 matches the number and position of the material feeding frame 2. It includes rail plates 52 symmetrically distributed on both sides, a first slider-rail structure 53 connected to the corresponding rail plates 52, and a screw adjusting structure 54 that acts on both rail plates 52 simultaneously. The rail plates 52 are moved through the first slider-rail structure 53. The screw adjusting structure 54 controls the synchronous inward or outward movement of the two rail plates 52 by rotation to adapt to the size of the placement space provided by the material feeding frame 2. On the high-order workbench surface 11, there are also third mounting brackets 30 symmetrically distributed on both sides. The third mounting brackets 30 are provided with restraint members 40 that match the number and position of the guiding rail 5. The restraint members 40 include a pressing plate 401 and three positioning rods 402 each equipped with a spring 4021. The rail plate 52 has an L-shaped configuration. The vertical part is used as the side stop for the raw material paper, and the horizontal part serves as the lower support for the raw material paper so that the raw material paper can move on the rail plate 52. When the screw adjusting structure 54 makes an adjusting rotation, its threaded fit with the vertical part of the rail plate 52 enables the rail plate 52 to displace inward or outward. The first slider-rail structure 53 responds to this displacement to cause the rail plate 52 to move, reducing or increasing the distance between the two rail plates 52, making the size of the placement space of the guiding rail 5 match the size of the placement space of the material feeding frame 2 and also match the cross-sectional size of the raw material paper. In this way, when the raw material paper is sent to the end point 513 of the conveying and stays there, it will not shift in position. Moreover, a first passing area 521 for the picking suction nozzle 331 to pass through is provided at the rear end of the rail plate 52, and a second passing area 522 for part of the forming mechanism to be placed inside the guiding rail 5 is provided at the front end. The screw adjusting structure 54 is composed of a screw shaft 541 and a shaft seat 542. The screw shaft 541 has a left-handed threaded fit with one of the rail plates 52 and a right-handed threaded fit with the other rail plate 52. The restraint member 40 is provided to prevent the raw material paper from shifting in position (the shift here refers to the forward or backward movement of the raw material paper) due to being lifted by the first push plate 641. Under the action of the positioning rod 402, the pressing plate 401 always maintains a fixed height position, that is, there is always a distance equal to the thickness of the raw material paper between it and the upper end surface of the rail plate 52. When the raw material paper is lifted, the positioning rod 402 will move correspondingly to adapt to the change in the height position of the raw material paper, but under the action of the spring 4021, an opposite acting force will be generated to clamp the raw material paper and use the clamping to prevent the raw material paper from shifting. After the first push plate 641 disengages, the pressing plate 401 can be reset under the action of the spring 4021. At the same time, considering the long use length of the pressing plate 401, elastic constraint points are set at both ends to maintain the balance and stability of the pressing plate 401 during use.

[0051] The gluing mechanism includes a glue machine 501 and a fourth mounting bracket 502. The glue machine 501 has a plurality of glue tube connection ports 5011. A glue tube 50111 is provided on each glue tube connection port 5011. The other end of the glue tube 50111 is provided with a dispensing gun 501111. The dispensing gun 501111 is placed on the guiding track 5. The fourth mounting bracket 502 is arranged on the frame 1. The glue machine 501 is located above the guiding track 5 through the fourth mounting bracket 501. The glue machine 501 has a plurality of glue tube connection ports 5011, so that a plurality of glue tubes 50111 can be equipped at the same time, thus meeting the need for gluing at multiple positions. The dispensing gun 501111 is used to glue the raw material paper so as to maintain the configuration of the shoe tree after being formed by the forming mechanism to the shoe tree, and the shoe tree has a heel.

[0052] The feeding mechanism includes two second slider-rail structures 61, two second mounting plates 62, a first connecting support 63 that matches the number and position of the guiding rails 5, and two feeding push members 64. The second slider-rail structures 61 are installed at the lower end of the frame 1 and are symmetrically distributed on both sides. The second mounting plates 62 are installed at the upper ends of the second slider-rail structures 61 and are symmetrically distributed on both sides. The first connecting support 63 is installed at the upper ends of the two second mounting plates 62. The feeding push members 64 are installed at the upper ends of the first connecting support 63 and are symmetrically distributed on both sides. The two mounting plates 62 are arranged considering that the first connecting support 63 is in a U-shaped configuration, and the connection stability provided to the first connecting support 63 is better after being connected to the two. The first connecting support 63 is configured in this way to respectively arrange a feeding push member 64 on the two vertical parts. One feeding push member 64 is located below the material placing frame 2 and is used to push the raw material paper staying at the starting end 511 before conveying towards the intermediate end 512 during conveying. The other feeding push member 64 is used to push the raw material paper staying at the intermediate end 512 during conveying towards the ending end 513 after conveying. The cross-section of the feeding push member 64 is in a U-shaped configuration, and first push plates 641 are arranged on both outer sides of the front end thereof. A second push plate 642 is arranged at the rear end of the feeding push member 64 located below the material placing frame 2. The upper end surface of the first push plate 641 is an inclined surface that gradually slopes from front to back. In this way, when the feeding push member 64 pushes the raw material paper staying at the intermediate end 512 during conveying to the ending end 513 after conveying and resets, the lower end of the inclined surface of the first push plate 641 can first be placed into the lower end of the raw material paper staying at the intermediate end 512 during conveying, and then be completely placed at the lower end as it moves. When the upper end of the inclined surface of the first push plate 641 contacts the raw material paper, part of the raw material paper will be lifted (the raw material paper undergoes a wavy morphological change when the first push plate 641 passes below), but there will be no pushing contact with the raw material paper. In this way, it is transposed from the front end of the raw material paper to the rear end of the raw material paper. After the transposition, the raw material paper completely falls back onto the guiding rail 5 again and also remains at the position of two-thirds of the height of the front end surface of the first push plate 641 and can be pushed by the first push plate 641. The second push plate 642 is only used to push the raw material paper from the starting end 511 before conveying to the intermediate end 512 during conveying. The second slider-rail structure 61 serves to move the feeding mechanism here.

[0053] The forming mechanism includes forming blocks 41 that match the number and position of the guiding tracks 5, and a forming mold 42. A second mounting frame 121 is provided on the lower working surface 12. The forming blocks 41 are movably mounted on the upper end of the second mounting frame 121. One end of the guiding track 5 extends to the lower working surface 12. The forming mold 42 is mounted on the lower working surface 12, and its upper end extends into the guiding track 5 located at the lower working surface 12. The forming blocks 41 are used to perform a stamping action on the raw paper. After being combined with the forming blocks 41, the forming mold 42 forms the raw paper into a shoe tree. And two forming blocks 41 are set as a group and jointly arranged on a connecting plate 411. Lifting structures identical to the lifting assembly 32 are also provided at the four corner positions of the connecting plate 411. And a first cylinder for driving the forming blocks 41 to move is provided at the upper end of the second mounting frame 121. And only one cylinder is equipped for the two forming blocks 41, which reduces energy consumption. At the same time, the upper end surface of the forming mold 42 and the upper end surface of the transverse part of the track plate 52 are kept at the same horizontal plane, so that the raw paper can enter the forming mold 42 immediately when being stamped, having good guiding property.

[0054] There are three limiting mechanisms, and each is adapted to two forming molds 42. It includes a third mounting plate 71, two hinges 72, and two baffle plates 73. The hinges 72 are arranged on the third mounting plate 71 and are symmetrically distributed on both sides. The hinge heads 721 of the hinges 72 are mounted on the upper end of the third mounting plate 71, and the bases 722 are mounted on the front end of the forming mold 42. The baffle plates 73 are mounted on the upper ends of the hinge heads 721. A second cylinder is also provided on the lower working surface 12. The output shaft of the second cylinder is rotationally connected to a connecting block 711 provided on the third mounting plate 71. And under the action of the hinges 72, when the second cylinder acts, it can quickly drive the third mounting plate 71 to flip, that is, it also drives the baffle plates 73 to flip, so as to realize the blocking or unblocking of the outlet end of the forming mold 42. At the same time, such a structural form enables only one second cylinder to be equipped for the two baffle plates 73, reducing energy consumption.

[0055] There are three discharging and material-taking mechanisms, which include a stroke actuator 81 capable of performing horizontal and vertical movements, a second connection support 82, and two discharging and material-taking suction nozzles 83. The stroke actuator 81 is installed at the lower end of the second mounting frame 121 and is located between two adjacent molding dies 42. The second connection support 82 is connected to the vertical movement part of the stroke actuator 81. The discharging and material-taking suction nozzles 83 are installed on the second connection support 82 and are symmetrically distributed on both sides, and each discharging and material-taking suction nozzle 83 corresponds to a molding die 42. Such a setting is the same as that of the limiting mechanism, that is, one discharging and material-taking mechanism is for two molding dies 42. The stroke actuator 81 enables the discharging and material-taking suction nozzles 83 to move in the horizontal and vertical directions, so that the position of the shoe tree can be accurately positioned. The second connection support 82 is also in a U-shaped configuration, so that two discharging and material-taking suction nozzles 83 can be set and connected to the vertical movement part of the stroke actuator 81 at the same time. The usage mode of the discharging and material-taking suction nozzles 83 is the same as that of the material-taking suction nozzle 331.

[0056] Three motors 9 equipped with gearboxes 91 are installed at the lower end of the frame 1. The two ends of the output shaft of the gearbox 91 are respectively provided with a first transmission structure 10 and a second transmission structure 20. The first transmission structure 10 and the second transmission structure 20 are distributed in a front-back staggered manner. Such a setting enables only one motor 9 to be equipped between the material-taking mechanism and the feeding mechanism, and the two transmission structures always operate in a front-back staggered manner, that is, when the material-taking mechanism moves upward, the feeding mechanism resets, or when the material-taking mechanism resets, the feeding mechanism moves forward, and no interference will occur. In this embodiment, the motor 9 can be a general motor or a servo motor.

[0057] The first transmission structure 10 is used to drive the material taking mechanism to move up and down. It includes a first shaft clamp 101, a first connecting shaft 102, a first universal ball joint rod 103, and a connecting outer ear 104. One end of the first shaft clamp 101 is connected to the output shaft of the reducer part of the motor 9, and the other end is used to connect the first connecting shaft 102. One end of the first universal ball joint rod 103 is rotatably connected to the end of the first connecting shaft 102 that is not connected to the first shaft clamp 101, and the other end is rotatably connected to the connecting outer ear 104. The connecting outer ear 104 is fixedly installed at the lower end of the first mounting plate 31. Through the first shaft clamp 101 and the first connecting shaft 102, the first universal ball joint rod 103 can change its position with the rotation of the output shaft of the gearbox 91. Also, under the action of the first shaft clamp 101, the first universal ball joint rod 103 is eccentrically arranged with respect to the output shaft of the gearbox 91. In this way, the position change of the first universal ball joint rod 103 is a circumferential change around the output shaft of the gearbox 91. Moreover, the first universal ball joint rod 103 is rotatably connected to the first connecting shaft 102 and the connecting outer ear 104 (with a shaft), so that there will be no interference during the position change. At the same time, both the output shaft of the gearbox 91 and the gearbox 91 itself are provided with gears 911, and the two gears 911 cooperate with each other. This method is used to increase the stability of the output shaft of the gearbox 91 during rotation.

[0058] The second transmission structure 20 is used to drive the feeding mechanism to move back and forth. It includes a second shaft clamp 201, a second connecting shaft 202, a second universal ball joint rod 203, a first slider 204, a transmission rod 205, a third universal ball joint rod 206, a second slider 207, a shaft seat 208, and a connecting rod 209. One end of the second shaft clamp 201 is connected to the output shaft of the gearbox 91, and the other end is used to connect the second connecting shaft 202. One end of the second universal ball joint rod 203 is rotatably connected to the end of the second connecting shaft 202 that is not connected to the second shaft clamp 201, and the other end is connected to the first slider 204. The first slider 204 slides on the middle and lower end of the transmission rod 205. One end of the third universal ball joint rod 206 is connected to the second slider 207, and the other end is rotatably connected to the connecting rod 209. The second slider 207 slides on the upper end of the transmission rod 205. The shaft seat 208 is fixedly installed at the lower end of the frame 1 and is rotatably connected to the lower end of the transmission rod 205. The connecting rod 209 is fixedly installed at the lower ends of the two second mounting plates 62. The mode of the second transmission structure 20 is similar to that of the first transmission structure 10, but there are differences. Because the first transmission structure 10 needs to drive the material taking mechanism to move up and down, while the second transmission structure 20 is used to drive the feeding mechanism to move back and forth. That is, a second universal ball joint rod 203 and a third universal ball joint rod 206 are respectively arranged on the second connecting shaft 202 and the connecting rod 209 (with a shaft), and then a transmission rod 205 is arranged between the two universal ball joint rods. There are two sliding grooves on the transmission rod 205. A first slider 204 connected to the second universal ball joint rod 203 slides in one of the sliding grooves, and a second slider 207 connected to the third universal ball joint rod 206 slides in the other sliding groove. And the transmission rod 205 is also limited by the shaft seat 208, so that the movement form of the transmission rod 205 can only be swinging, and the slider is such that when the transmission rod 205 swings, the universal ball joint rod can move accordingly, so as to avoid interference when the position changes through the movement.
