Description

Technical Field

[0001] The utility model relates to the technical field of tire vulcanization shaping, in particular to a post-inflation device of a tire vulcanizer. Background Art

[0002] The post-inflation device is an important part of the tire vulcanizer. It is used to inflate, cool and shape the tires with high temperatures after vulcanization in the vulcanizer. For tires with nylon or polyester fiber cords as the skeleton material, due to their large elongation and thermal shrinkage characteristics, the tires will collapse and have irregular surfaces when they are just vulcanized. Therefore, after the tires are vulcanized and demolded, they should be quickly inflated with internal pressure through the post-inflation device while the temperature is still high, so that the tires can be cooled and shaped under tension to maintain the correct size and physical properties of the tires, avoid defects such as concave tire surface and bead deformation caused by the cooling of the tires in the natural state, reduce permanent deformation of the tire carcass, and ensure the quality of the tires.

[0003] The general four-station flip type rear inflation device mainly includes a frame, a central device, a movable beam, a flip mechanism and a roller. Fig. 9 As shown, each central device of the rear inflation device corresponds to an inflation station, which includes upper and lower chucks, upper and lower disc seats, a locking rod 2, a stud 18, a positioning plate 19, etc. One end of the locking rod 2 is connected and fixed to the flip beam 1, the upper and lower disc seats are sleeved on the locking rod 2, the upper chuck 31 is adaptively connected to the upper disc seat 3, the lower chuck 41 is adaptively connected to the lower disc seat 4, the upper and lower chucks are positioned relative to each other and are used to clamp the inflated and cooled tire, the lower disc seat 4 is fixedly connected to the movable beam 6, and the movable beam 6 can be controlled to rise and fall by a lifting cylinder (not shown in the figure) connected thereto. During operation, the movable beam 6 is first driven down by the lifting cylinder, and the movable beam 6 drives the lower chuck 41 to move down. Then, the tire that needs to be inflated and cooled is transported to the inflation station through external equipment such as rollers, and the tire is placed on the lower chuck 41. The movable beam 6 and the lower chuck 41 are then driven up by the lifting cylinder, so that the upper and lower chucks are in contact with and clamp the tire, and the tire surface is compacted and sealed. The rear inflation device inflates, cools and shapes the tire. After the processing is completed, the lower chuck 41 is driven down by the lifting cylinder, and the processed tire is moved away from the inflation station by rollers and other equipment to the subsequent process.

[0004] Since the range of motion of the lifting cylinder is fixed, that is, the position of the movable beam and the lower chuck is fixed, when changing tires of different specifications for inflation and cooling, the distance between the upper and lower chucks, that is, the distance between the chucks, needs to be adjusted through the distance adjustment structure of the rear inflation device, so that the rear inflation device can compact and seal the tire during processing. Fig. 9As shown, the existing distance adjustment structure of the rear inflation device needs to rotate the lower disc seat 4 manually. The lower disc seat 4 is connected to the stud 18 by a threaded connection, so that the lower disc seat 4 can move up and down along the stud 18, thereby adjusting the chuck spacing a between the upper and lower chucks to match the tire specifications. After adjusting the chuck spacing a, the positioning plate 19 is inserted into the groove of the lower disc seat to fix its position and prevent it from loosening. However, the above-mentioned distance adjustment structure relies on manual operation. Whenever a tire of different specifications needs to be replaced, the operator needs to climb onto the machine and manually adjust the chuck spacing in the above manner, and the chuck spacing of each station needs to be adjusted separately. The equipment has a low degree of automation and is not convenient to operate. In addition, due to the heavy weight of the lower disc seat, the operator needs to use a large force to rotate it to change its position, which makes the work intensity high and the adjustment speed slow, resulting in extended processing time and low efficiency. It is difficult to accurately adjust the distance by manual force, which reduces the adjustment accuracy. In addition, when the operator performs the above-mentioned processing, he needs to be directly close to the working machine equipment, so there is still a certain safety risk. Utility Model Content

[0015] A driven gear is fixedly connected to one end of the inner and outer screw nuts close to the turning beam;

[0016] The driving gear is a cylindrical structure, meshing with the driven gear on the outside, the tooth width of the driving gear is greater than the tooth width of the driven gear, so that the driven gear will not be separated from the driving gear when it moves up and down with the inner and outer screw nuts, and a connecting hole with a keyway is provided at one end of the driving gear close to the flip beam;

[0017] A reducer fixedly connected to the flip beam is provided between each group of upper and lower inflation stations, and the reducer is provided with two synchronously rotating output shafts, and keys adapted to the key slots are provided on the two output shafts. The two output shafts are respectively connected to the driving gears on the central device above and below the reducer by inserting the connecting holes and adapting the keys to the key slots. The ends of the output shafts are fixed with glands by bolts so that the output shafts will not be separated from the driving gears, and the two output shafts respectively drive the driving gears above and below the reducer to rotate synchronously;

[0018] In each group of upper and lower inflation stations, the rotation directions of the transmission threads at corresponding positions are arranged in opposite directions.

[0024] Furthermore, a locking portion is provided at one end of the locking rod close to the lower disc seat, and a locking groove matching the locking portion is provided in the lower disc seat.

[0028] During the working process of the utility model, when a group of upper and lower inflation stations need to replace tires of different specifications for inflation and cooling, the operator can control the reducer corresponding to the group of upper and lower inflation stations to work, so that the two output shafts of the reducer rotate synchronously according to the set operation mode, and the output shaft of the reducer is connected to the connecting hole of the driving gear, driving the driving gears with a certain width on the inflation stations above and below it to rotate in the corresponding direction; in each station, the driving gear drives the driven gear meshing with it to rotate in the opposite direction, and the rotation of the driven gear causes the inner and outer screw nuts fixedly connected thereto to rotate around the locking rod accordingly; because the transmission threads on the inner sides of the inner and outer screw nuts match the transmission threads on the outer sides of the adjusting studs, the inner and outer screw nuts can make axial movements along the locking rod in the direction close to or away from the flip beam during the rotation process; and the transmission threads on the outer sides of the inner and outer screw nuts match the transmission threads on the inner sides of the distance-adjusting inner screw nuts, and the inner and outer transmission threads of the inner and outer screw nuts rotate in opposite directions, so the distance-adjusting inner screw nut will also move in the same moving direction as the inner and outer screw nuts; and The cam is then moved in a direction opposite to the rotation direction of the inner and outer nuts above the upper and lower inflation stations, and the cam is moved in a direction opposite to the rotation direction of the inner and outer nuts below the upper and lower inflation stations. Therefore, the inner and outer nuts and the adjustable inner nut at the upper and lower stations will synchronously move axially toward or away from the direction of the inflation beam; the guide rod connected and fixed to the adjustable inner nut will be restricted by the guide seat through which it passes, so that the guide rod moves in the vertical direction of the guide seat, so that the adjustable inner nut moves axially along the locking rod under the guidance of the guide rod without rotating and tilting, thereby ensuring a good subsequent inflation sealing effect, and its movement speed relative to the adjusting stud on the same station is twice the movement speed of the inner and outer nuts relative to the adjusting stud; the adjustable inner nut can drive the upper disc seat and the upper chuck fixedly connected thereto to move axially in the same direction, so that the upper chucks of the same group of upper and lower inflation stations are synchronously close to or away from the position of their lower chucks, thereby changing the chuck spacing of the corresponding stations until it is adapted to the tire specifications, causing the reducer to stop working, and subsequent processing can be carried out.

[0029] Therefore, the beneficial effects of the utility model are as follows: when it is necessary to adjust the distance between the chucks, the operator can control the rotation time and direction of the reducer corresponding to the workstation to be adjusted in the utility model, and under the transmission effect of the gear rotation and the transmission thread, the movement position of the upper chuck in the direction of the locking rod axis can be controlled, thereby adjusting the distance between the chucks of the workstation according to the specifications of the tire, and the distance between the chucks on a group of upper and lower inflation workstations of the flip beam can be adjusted synchronously, and the operator does not need to climb onto the machine and use operating tools to manually adjust the position of the chucks on each workstation, making the process of adjusting the distance between the chucks more convenient and improving the degree of automation of the equipment; the operator does not need to apply force manually, reducing his work intensity; and the above-mentioned structure can make the movement speed during adjustment faster, which can effectively shorten the time for adjusting the chuck, improve the adjustment efficiency, and can more conveniently control the movement direction of the chuck, thereby improving the accuracy of adjustment; during adjustment, the operator does not need to approach the working machine workstation, thereby ensuring the operator's work safety.

In addition, in the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly specified and limited.

[0043] like Figures 1 to 4 As shown, the utility model provides a tire vulcanizer post-inflation device, comprising a frame 100, a turnover mechanism 110, a movable mechanism 120, and a central device 130, wherein:

[0044] The flip mechanism 110 is located at the upper part of the frame 100, and includes a flip beam 1 and a flip motor 111 that drives the flip beam 1 to rotate around its central axis. A group of upper and lower inflation stations are provided on both sides of the flip beam 1. Each group of upper and lower inflation stations includes two central devices 130 that are symmetrically arranged with the flip beam 1 as the axis. Each central device 130 corresponds to an inflation station, thereby forming a four-station rear inflation device.

[0045] The movable mechanism 120 is located in the middle of the flip beam 1, and includes a movable beam frame 121 fixedly connected to the flip beam 1, two movable beams 6 respectively connected to the upper and lower ends of the movable beam frame 121, and a lifting cylinder 122 arranged on the movable beam frame 121 and capable of driving the movable beam 6 to move up and down;

[0046] The central device 130 includes a locking rod 2, an upper disc seat 3, an upper chuck 31, a lower disc seat 4, and a lower chuck 41. One end of the locking rod 2 is fixedly connected to the flip beam 1. The upper disc seat 3 is sleeved on the locking rod 2. The upper chuck 31 is adapted to be installed on the outer side of the upper disc seat 3. The lower disc seat 4 is fixedly connected to the movable beam 6. The lower chuck 41 is adapted to be installed on the outer side of the lower disc seat 4 and is opposite to the upper chuck 31.

[0047] The central device 130 also includes:

[0048] The adjusting stud 11 is sleeved on the locking rod 2, and one end of the adjusting stud 11 close to the flip beam 1 is fixedly connected to the flip beam 1, and a transmission thread is arranged on the outer side, and a guide seat 17 facing the vertical direction is connected to the outer side;

[0049] The inner and outer nut 12 is sleeved on the adjusting stud 11, and the inner and outer sides thereof are provided with transmission threads with opposite rotation directions, and the transmission threads on the inner side thereof match with the transmission threads on the outer side of the adjusting stud 11;

[0050] The distance-adjustable inner screw nut 13 is sleeved on the inner and outer screw nuts 12, and a transmission thread is provided on the inner side thereof and matches with the outer transmission thread of the inner and outer screw nuts 12, and one end thereof away from the flip beam 1 is fixedly connected to the upper disc seat 3;

[0051] A guide rod 14, one end of which is fixedly connected to the distance-adjusting inner screw nut 13, and a middle portion of which passes through a guide seat 17 and can move up and down in the guide seat 17;

[0052] A driven gear 15, which is fixedly connected to one end of the inner and outer screw nuts 12 close to the flip beam 1;

[0053] The driving gear 16 is a cylindrical structure, and the outer side is meshed with the driven gear 15. The tooth width of the driving gear 16 is greater than the tooth width of the driven gear 15, so that the driven gear 15 will not be separated from the driving gear 16 when it moves up and down with the inner and outer screw nuts 12. The driving gear 16 is provided with a connecting hole 52 with a keyway at one end close to the flip beam 1;

[0054] A reducer 5 fixedly connected to the flip beam 1 is provided between each group of upper and lower inflation stations, and the reducer 5 is provided with two synchronously rotating output shafts 51, and the two output shafts 51 are provided with keys adapted to the key slots. The two output shafts 51 are respectively connected to the driving gears 16 on the central device 130 above and below the reducer 5 by inserting the connecting holes 52 and making the keys adapted to the key slots. The ends of the output shafts 51 are fixed with glands 53 by bolts, so that the output shafts 51 will not be separated from the driving gears 16, and the two output shafts 51 respectively drive the driving gears 16 above and below the reducer 5 to rotate synchronously;

[0055] In each group of upper and lower inflation stations, the rotation directions of the transmission threads at corresponding positions are arranged in opposite directions.

[0056] In the working process of the utility model, when a group of upper and lower inflation stations need to replace tires 9 of different specifications for inflation and cooling, the operator can control the reducer 5 corresponding to the group of upper and lower inflation stations to work, so that the two output shafts 51 of the reducer 5 rotate synchronously according to the set operation mode, such as Figures 4 to 6 As shown, the output shaft 51 of the reducer 5 is connected to the connecting hole 52 of the driving gear 16, driving the driving gears 16 with a certain width on the inflation stations above and below it to rotate in the corresponding direction. In each station, the driving gear 16 drives the driven gear 15 matched with it to rotate in the opposite direction, and the rotation of the driven gear 15 causes the inner and outer screw nuts 12 fixedly connected thereto to rotate around the locking rod 2 accordingly.

[0057] The driving gear 16 is configured as a cylindrical structure, which is hollow inside to reduce its weight. Figure 4 and Figure 5 As shown, the tooth width of the driving gear 16, that is, the axial length of the gear, is greater than the tooth width of the driven gear 15, so that when the inner and outer screw nuts 12 drive the driven gear 15 to move up and down, the driven gear 15 will not deviate from the axial range of the driving gear 16, ensuring that the driving gear 16 and the driven gear 15 always remain in meshing during operation, and the contact line between the two remains at the tooth width of the driven gear 15, and the length of the contact line will not be reduced. The radius of the driven gear 15 can be as follows Figure 5 As shown, it is set to be smaller than the radius of the driving gear 16, so that the rotation speed of the driven gear 15 is slightly slower than that of the driving gear 16, so that the subsequent up and down movement of the inner and outer screw nuts 12 is smooth, which is convenient for accurately adjusting the chuck spacing.

[0058] Since the transmission threads on the inner side of the inner and outer screw nuts 12 match the transmission threads on the outer side of the adjusting stud 11, the inner and outer screw nuts 12 can move axially along the locking rod 2 in the direction close to or away from the flip beam 1 during the rotation process; and the transmission threads on the outer side of the inner and outer screw nuts 12 match the transmission threads on the inner side of the distance-adjusting inner screw nut 13, and the inner and outer transmission threads of the inner and outer screw nuts 12 rotate in opposite directions, so the distance-adjusting inner screw nut 13 will also move in the same moving direction as the inner and outer screw nuts 12, that is, the distance-adjusting inner screw nut 13 and the inner and outer screw nuts 12 both move axially in the same direction close to or away from the flip beam 1. Since the up and down movement of the distance-adjusting inner screw nut 13 is transmitted through the two-stage transmission thread structure, its moving speed relative to the adjusting stud 11 is twice the moving speed of the inner and outer screw nuts 12 relative to the adjusting stud 11, and it can move to the desired position faster during adjustment.

[0059] Furthermore, since the transmission thread rotation directions at the corresponding positions in each group of upper and lower inflation stations are opposite, that is, the thread rotation directions of the inner and outer nuts 12 above the flip beam 1 and the inner and outer nuts 12 below are also opposite, the inner and outer nuts 12 and the adjustable inner nut 13 at the upper and lower stations will all move axially toward or away from the flip beam 1 synchronously.

[0060] The adjustable inner nut 13 can drive the upper disc seat 3 and the upper chuck 31 fixedly connected thereto to move axially in the same direction, so that the upper chucks 31 of the same group of upper and lower inflation stations are synchronously close to or away from the position of the lower chuck 41, thereby changing the chuck spacing of the corresponding stations until it is adapted to the specifications of the tire 9, controlling the corresponding reducer 5 to stop working, the upper disc seat 3 and the upper chuck 31 to stop moving, and the position is fixed, so that subsequent inflation and cooling processing of the tire 9 can be carried out.

[0061] When the adjustable inner screw nut 13 moves, the guide rod 14 connected and fixed to the adjustable inner screw nut 13 will be restricted by the guide seat 17 through which it passes, so that the guide rod 14 moves along the vertical direction of the guide seat 17. Therefore, the adjustable inner screw nut 13 moves axially along the locking rod 2 under the guidance of the guide rod 14 without rotating and tilting, thereby ensuring a good subsequent inflation and sealing effect. The number of guide rods 14 and their corresponding guide seats 17 to be installed is not specifically limited here, and can be as follows Figure 2 As shown, a set of guide rods 14 and their corresponding guide seats 17 are installed on both sides of each inflation station to achieve a better limiting effect on the distance adjusting inner screw nut 13.

[0062] like Figure 1As shown, since a group of upper and lower inflation stations are provided on both sides of the flip beam 1, each group of upper and lower inflation stations includes two central devices 130 symmetrically arranged with the flip beam 1 as the axis, and each central device 130 corresponds to an inflation station, thereby forming a four-station rear inflation device. The flip beam 1 is connected to a flip motor 111, which can drive the flip beam 1 to rotate around its central axis through the flip motor 111, so that the two groups of upper and lower inflation stations on the flip beam 1 rotate around the central axis of the flip beam 1 to change the upper and lower position relationship of each station. After the stations below the flip beam 1 clamp the tire 9, the flip motor 111 can be controlled to rotate the flip beam 1, so that the station clamping the tire 9 is located above the flip beam 1, and the station opposite to it is turned to the bottom to perform the clamping and unloading work of the tire 9, thereby improving the work efficiency.

[0063] Reference Figure 1 As shown, the lower disc seat 4 is fixedly connected to the movable beam 6, and a lifting cylinder 122 connected to the movable beam 6 and capable of driving the movable beam 6 to move up and down is provided on the movable beam frame 121. With the above structure, when the rear inflation device clamps and unloads the tire 9, the lifting cylinder 122 controls the lifting of the movable beam 6 to drive the lower disc seats 4 and the lower clamping plate 41 on the upper or lower side of the movable beam 6 to move up and down, so that the lower disc seats 4 and the lower clamping plate 41 on the corresponding station can cooperate with the upper clamping plate 31 on the corresponding station to clamp or unload the tire 9.

[0064] Specifically, after the adjustment of the chuck spacing is completed, the rear inflation device is used to inflate, cool and shape the tire 9. First, the movable beam 6 located below the flip beam 1 is driven downward by the lifting cylinder 122, and the lower chuck 41 at the workstation below the flip beam 1 moves downward together with the movable beam 6. Then, the tire 9 is transported and placed above the lower chuck 41 through external transportation equipment such as rollers under the frame 100. The corresponding movable beam 6 and lower chuck 41 are then raised by the lifting cylinder 122. When the lower chuck 41 rises, it drives the tire 9 above it to move upward together, so that it gradually approaches the position of the upper chuck 31. When the lower chuck 41 moves up to the chuck spacing with the upper chuck 31, the upper chuck 31 and the lower chuck 41 clamp the tire 9 and compact and seal the tire 9 surface. Then, the rear inflation device is controlled to inflate, cool and shape the tires 9 on the two workstations below the flip beam 1. After the processing of the above two workstations is completed, the lower chuck 41 is driven downward by the lifting cylinder 122, so that the lower chuck 41 moves downward with the processed tire 9. After moving to a certain position, the transportation equipment under the frame 100, such as a roller, is used to move the tire 9 to the subsequent process for processing, and then the next batch of tires 9 are inflated and cooled.

[0065] When the two stations are performing the inflation cooling treatment, the flipping beam 1 can be rotated by the flipping motor 111, and the two stations on the opposite side can be transferred to the bottom to clamp and unload the tire 9. After the two stations complete the processing, they can be rotated back to the bottom to unload the tire 9 and transport it to improve work efficiency. In addition, since the distance between the chucks on each group of upper and lower inflation stations is adjusted synchronously, when using the rear inflation device of the utility model, tires 9 of the same specifications can be arranged to be processed on the same group of upper and lower inflation stations. After the distance between the chucks of the same group of upper and lower inflation stations is determined, it can be continuously flipped and used without repeated adjustment, making the operation process more convenient and improving work efficiency.

[0066] When the utility model is used and the distance between the chucks needs to be adjusted, the operator can control the rotation time and direction of the reducer 5 corresponding to the workstation to be adjusted, and under the transmission effect of the gear rotation and the transmission thread, the movement position of the upper chuck 31 in the axial direction of the locking rod 2 can be controlled, so as to adjust the distance between the chucks of the workstation according to the specifications of the tire 9, and the distance between the chucks on a group of upper and lower inflation workstations of the flip beam 1 can be adjusted synchronously; by setting the guide seat 17, the guide rod 14 can be further stabilized in the vertical direction to play a good guiding role, so as to avoid the upper chuck 31 from tilting during the movement, and ensure that the rear inflation device has a good inflation sealing effect during subsequent inflation and cooling. When adjusting the distance, the operator no longer needs to climb onto the machine and use operating tools to manually adjust the position of the chucks on each workstation, which makes the process of adjusting the chuck spacing more convenient and improves the degree of automation of the equipment; the operator does not need to apply force manually, which reduces his work intensity; and the above structure can make the movement speed during adjustment faster, which can effectively shorten the time for adjusting the chuck, improve the adjustment efficiency, and can more conveniently control the movement direction of the chuck, thereby improving the accuracy of adjustment; when adjusting, the operator does not need to approach the working machine station, thereby ensuring the operator's work safety.

[0067] Further, such as Figure 2 and Figure 3 As shown, the upper disc seat 3 is connected to a tire-lifting cylinder 20, and the tire-lifting cylinder 20 can push the upper disc seat 3 to move up and down. Before the tire 9 is inflated, cooled and shaped, the tire-lifting cylinder 20 is used to push the upper disc seat 3 to one side of the tire 9, driving the upper clamping plate 31 to provide extrusion force to the tire 9, and cooperating with the lower clamping plate 41 to clamp and compact the tire surface, and then inflate and cool it to make the tire 9 firmly sealed, so as to prevent the tire 9 from leaking during the inflation process, resulting in poor shaping effect, or causing safety accidents due to unstable position.

[0068] Further, such as Figure 2As shown, a distance-adjusting ruler 22 with a scale is fixedly installed on the flip beam 1, and a distance-adjusting pointer 21 with an arrow is connected to the distance-adjusting inner nut 13, and the arrow of the distance-adjusting pointer 21 points to the scale on the distance-adjusting ruler 22. The up and down movement of the distance-adjusting inner nut 13 can drive the distance-adjusting pointer 21 connected thereto to change its position up and down, so that its arrow points to different scale positions on the distance-adjusting ruler 22. Therefore, the operator can easily check the specific distance value of the adjustment by observing the scale pointing of the distance-adjusting pointer 21 on the distance-adjusting ruler 22, so as to confirm the adjustment of the chuck spacing, thereby setting a suitable chuck spacing, eliminating the step of manual measurement, further facilitating the distance-adjusting process of the operator, and further improving the accuracy of the distance adjustment. Since the tire-pushing cylinder 20 is connected to the upper disc seat 3 during the distance adjustment process, and the upper disc seat 3 is also fixedly connected to the distance-adjusting inner nut 13, it can be as shown Figure 2 As shown, the distance adjustment pointer 21 is installed on the tire-lifting cylinder 20, and the distance adjustment pointer 21 is connected to the distance adjustment inner screw nut 13 through the tire-lifting cylinder 20, so that the distance adjustment pointer 21 can move up and down with the lifting and lowering of the upper disc seat 3 and the distance adjustment inner screw nut 13, making the installation more convenient. Of course, the connection between the distance adjustment pointer 21 and the distance adjustment inner screw nut 13 can also be other ways, which are not specifically limited here.

[0069] Further, such as Figure 2 and Figure 3 As shown, the upper disc seat 3 is connected to telescopic brackets 32 on both sides, and a tire-pushing cylinder 33 is provided on the telescopic brackets 32. When the rear inflation device is inflated and the tire is unloaded, the tire 9 is easily adhered to the upper chuck 31 and cannot be automatically and quickly removed in a short time, resulting in the lower chuck 41 not being able to smoothly carry the tire 9 down when it moves down, affecting the subsequent moving process. Therefore, the tire-pushing cylinder 33 is installed on the left and right sides of the upper disc seat 3 through the telescopic brackets 32, so that the tire 9 can be pushed to fall off and separate from the upper chuck 31 faster after the inflation process is completed. The telescopic bracket 32 ​​is provided with slots, and the telescopic bracket 32 ​​can adjust the position of the tire-pushing cylinder 33 according to the different diameters of the tire 9, so that it can align and smoothly push the tire 9, unload the tire 9 from the work station, and improve the working speed.

[0070] Furthermore, the transmission threads on the adjusting stud 11, the inner and outer nuts 12, and the adjustable inner nut 13 are all trapezoidal threads. The trapezoidal threads have a low manufacturing cost, good self-locking performance, and can withstand a large load. Therefore, they can reduce loosening or falling off caused by vibration or external force, making them more stable; and their transmission effect is relatively efficient, and can effectively convert the rotational motion between the stud and the nut into linear axial motion, making the position adjustment more precise.

[0071] Furthermore, the reducer 5 is specifically an on-axis worm gear reduction motor. This reducer 5 is provided with a worm transmission structure composed of a worm and a worm wheel. This structure facilitates obtaining a larger transmission ratio. When the driving gear 16 is driven to rotate, the driving gear 16 can be set to rotate smoothly at a lower and appropriate speed, so that the driven gear 15, the inner and outer screw nuts 12, the adjustable inner screw nut 13, etc. driven by it can all move smoothly, and it is convenient for the operator to more accurately adjust the chuck position and improve the adjustment accuracy of the chuck spacing; it has a compact structure, small size, light weight, can save space, and it works smoothly, with relatively small impact, vibration, and noise during operation, and is suitable for complex factory environments. Figure 4 and Figure 5 As shown, the reducer 5 adopts a double-output shaft style, and its two output shafts 51 rotate synchronously so that the distance between the chucks of each group of upper and lower inflation stations can be adjusted synchronously.

[0072] Further, such as Figure 2 As shown, the locking rod 2 is provided with a locking portion 42 at one end close to the lower disc seat 4, and the lower disc seat 4 is provided with a locking groove 43 matched with the locking portion 42. When the locking groove 43 is positioned relative to the locking portion 42, the locking portion 42 can move in and out of the locking groove 43. When the locking portion 42 extends into the locking groove 43 and is misaligned, the locking portion 42 can be prevented from being separated from the locking groove 43. Through the above structure, when the upper and lower chucks clamp the tire 9 for inflation, the locking effect of the locking portion 42 and the locking groove 43 prevents the lower disc seat 4 and the lower chuck 41 from being separated from the locking rod 2, ensuring that the lower chuck 41 will not deviate or fall off during inflation and cooling, and ensuring smooth inflation and cooling. Among them, the locking portion 42 can be a cross-shaped lock head, and the locking groove 43 can be a cross-shaped groove adapted thereto, or of course, it can be other shapes, and its specific shape is not specifically limited in this solution.

[0073] Furthermore, if Figure 7 As shown, the locking rod 2 is connected with a brake arm 44 that can rotate the locking rod 2 around its central axis. The locking rod 2 is rotated by changing the position of the brake arm 44, thereby changing the relative relationship between the locking portion 42 and the locking groove 43. When the lower disc seat 4 and the lower clamping plate 41 need to be locked to the locking rod 2, the locking portion 42 only needs to be aligned and inserted into the locking groove 43, and then the locking rod 2 is rotated by a certain angle through the brake arm 44, so that the locking portion 42 and the locking groove 43 are misaligned, which can play a role in blocking the disengagement. When it is necessary to disengage, just follow the reverse steps. In order to facilitate the control of the rotation of the locking rod 2, the brake arm 44 can be connected to a push-pull cylinder, and the position of the brake arm 44 is controlled by the push-pull cylinder, so that the locking rod 2 is rotated, and the relative relationship between the locking portion 42 and the locking groove 43 is changed. Of course, other methods can also be used to control the position of the brake arm 44.

[0074] Furthermore, if Figure 1 As shown, the frame 100 is provided with a control device 7 that can control the working state of the reducer 5. In this embodiment, an operating cabinet is taken as an example. The operating cabinet is used as a control device 7, on which multiple buttons can be set, including buttons with corresponding functions of width adjustment, narrow adjustment, and stop, so that the reducer 5 can be in different working states. Specifically, when it is necessary to replace a set of upper and lower inflation stations with a wider tire 9 for inflation and cooling, the operator only needs to press the button with the corresponding function of width adjustment on the operating cabinet to rotate the two output shafts 51 of the reducer 5, driving the driving gears 16 with a certain width above and below it to rotate in the corresponding direction, and the driving gear 16 drives the driven gear 15 matched with it to rotate in the opposite direction, and the inner and outer nuts 12 fixedly connected to the driven gear 15 also rotate accordingly. Since the inner and outer screw nuts 12 are provided with transmission threads matched with the adjusting studs 11 and the distance adjusting inner screw nuts 13, the inner and outer screw threads of the inner and outer screw nuts 12 are opposite in rotation direction, and the inner and outer screw nuts 12 located above the turning beam 1 and the inner and outer screw nuts 12 located below the turning beam 1 are also opposite in rotation direction, the upper and lower inner and outer screw nuts 12 will all move axially toward the turning beam 1, and the distance adjusting inner screw nuts 13 will not rotate due to the restriction of the guide rod 14, so the upper and lower distance adjusting inner screw nuts 13 together with the upper disc seat 3 connected thereto will also move axially toward the turning beam 1, and the moving speed of the distance adjusting inner screw nuts 13 relative to the adjusting studs 11 on the same side is twice that of the inner and outer screw nuts 12 on the same side. The upper disc seat 3 drives the upper chuck 31 to move toward the turning beam 1 along with the distance adjusting inner screw nuts 13, so that the distance between the chucks gradually increases, and its specific value can be confirmed by the distance adjusting pointer 21 moving with the upper disc seat 3 pointing to the scale of the distance adjusting scale 22.

[0075] When the distance adjustment pointer 21 points to the required position on the distance adjustment scale 22, that is, the chuck spacing is adapted to the specifications of the tire 9, the operator presses the corresponding stop button on the control device 7 to stop the reducer 5 and the upper chuck 31 from moving. At this time, the chuck spacing adjustment is completed, and the rear inflation device can perform subsequent inflation and cooling operations on the tire 9.

[0076] When replacing a tire 9 with a narrower specification for inflation and cooling, press the button with the corresponding function of narrowing on the control device such as the operating cabinet to rotate the reducer 5 in the direction opposite to the above direction. Similarly, the upper and lower adjustable inner screw nuts 13 together with the upper disc seat 3 connected thereto are moved axially in the direction away from the flip beam 1 to gradually reduce the distance between the chucks. When the distance adjustment pointer 21 points to the required position on the distance adjustment scale 22, the operator presses the button with the corresponding function of stopping to stop the reducer 5 and the upper chuck 31 from moving. The adjustment of the distance between the chucks is completed and subsequent operations are carried out.

[0077] Of course, the control device 7 is not limited to the above structure, and can also be other control devices or equipment, such as various operation panels, control boxes, etc., as long as it can control the working state of the reducer 5, and its installation position is not limited to the frame 100, it can also be installed in other positions, or work by remote control, which will not be described in detail here.

[0078] To facilitate the transportation of tires 9, Figure 1 As shown, a sloped transport roller 140 is provided below the frame 100, and a tire blocking arm 141 is provided on the transport roller 140. Figure 8 As shown, a transport roller 140 with an inclination is provided. Before the tire 9 is inflated, the position of the tire stop arm 141 can be adjusted according to the specifications and parameters of the tire 9 to ensure that the tire stop arm 141 can block the movement of the tire 9 along the transport roller 140 after being rotated and lifted, so that it can stop at a position corresponding to the inflation station to meet the tire blocking requirements. After the inflation is completed, the tire stop arm 141 can be rotated and dropped back to allow the processed tire 9 to continue to slide along the transport roller 140. During operation, the movable beam 6 is driven down by the lifting cylinder 122, and the movable beam 6 drives the lower chuck 41 to move down, and then the transport roller 140 transports the tire 9 that needs to be inflated and cooled from the previous process equipment to the inflation station, and the rear inflation device can drive the tire blocking arm 141 to rotate through the cylinder, etc., and the tire 9 is placed on the lower chuck 41 through the blocking effect of the tire blocking arm 141, and then the movable beam 6 and the lower chuck 41 are driven up by the lifting cylinder 122, so that the upper and lower chucks are in contact with the tire 9 and clamp the tire 9, and the tire surface is compacted and sealed, and the rear inflation device inflates and cools the tire 9 to shape it; after the processing is completed, the lower chuck 41 is driven down by the lifting cylinder 122, the tire blocking arm 141 rotates and falls back, and the tire 9 continues to slide along the transport roller 140 to the subsequent process for processing.
