Description

Technical Field

[0001] This utility model belongs to the field of solid tire technology, specifically relating to an automatic feeding device for wrapping solid tires with rubber. Background Technology

[0002] In the existing technology, when loading tires, workers need to push a trolley to a designated location and then manually put the rubber sleeve onto the wrapping equipment. This not only requires manual loading but also requires ensuring the alignment of the rubber sleeve when putting it onto the wrapping equipment, which places high demands on the workers and is prone to problems such as inaccurate alignment affecting the wrapping quality. Utility Model Content

[0003] This utility model proposes an automatic feeding device for wrapping solid tires with rubber, which can achieve precise feeding of solid tires and also helps to reduce labor costs.

[0004] Therefore, the technical solution adopted by this utility model is as follows: an automatic feeding device for wrapping solid tires with rubber, including a material taking and retracting device set on a three-axis moving assembly, and the material taking and retracting device has an unfolding and retracting function so that it can fix the rubber sleeve from the inside. The bottom surface of the three-axis moving assembly is provided with a trolley fixing assembly for fixing the automatic trolley. The right side of the three-axis moving assembly is provided with a rubber sleeve positioning assembly for realizing automatic alignment of the rubber sleeve.

[0005] As a preferred embodiment of the above scheme, the material handling tensioner includes a material handling base mounted on a three-axis moving assembly and a contact member that extends vertically to contact the inside of the rubber sleeve.

[0017] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0018] like Figure 1-6 As shown, an automatic feeding device for solid tire wrapping mainly consists of a three-axis moving assembly 810, a material handling tensioner 820, a trolley fixing assembly 830, and a tire sleeve positioning assembly 840. The material handling tensioner 820 is mounted on the three-axis moving assembly 810 and has unfolding and retracting functions, allowing it to fix the tire sleeve from the inside. A trolley fixing assembly 830 is provided on the bottom surface inside the three-axis moving assembly 810 for fixing the automatic trolley. A tire sleeve positioning assembly 840 is provided on the right side of the three-axis moving assembly 810 for automatic tire sleeve alignment. The automatic trolley is used to transport the tire sleeve from the previous process to the feeding area of ​​the wrapping process; the automatic trolley is an AGV (Automated Guided Vehicle) trolley.

[0019] The three-axis moving assembly 810 includes a left-right moving assembly 811 set on columns spaced apart on the left and right sides, a front-back moving assembly 812 set on the left-right moving assembly 811, a vertical moving assembly 813 set on the front-back moving assembly 812, and a material take-up tensioner 820 set on the vertical moving assembly 813. To ensure the accuracy of the moving position, the left-right moving assembly, the front-back moving assembly, and the vertical moving assembly can adopt a gear and rack structure or a high-precision linear guide structure.

[0020] The material handling telescoping device 820 includes a material handling base 821 mounted on a three-axis moving assembly 810 and a contact member 822 that extends vertically to contact the inside of the rubber sleeve. A fixed cylinder 823 extending vertically is mounted on the bottom surface of the material handling base 821. A sliding cylinder 824 is slidably mounted inside the fixed cylinder 823. A material handling telescoping cylinder 825 is mounted on the material handling base 821. The telescoping end of the material handling telescoping cylinder 825 passes through the material handling base 821 and is mounted on the upper end of the sliding cylinder 824. At least three contact members 822 are provided, and the contact members 822 are connected to the fixed cylinder 823 through a telescoping structure.

[0021] Specifically, the telescopic structure includes two sliding blocks 826 and two fixed blocks 827 sleeved outside the fixed cylinder 823. The sliding blocks 826 can slide up and down relative to the fixed cylinder 823. The sliding blocks 826 and the fixed blocks 827 are staggered vertically. Each contact member 822 has a long connecting rod 828 hinged to its upper and lower ends. The other end of each long connecting rod 828 is hinged to the sliding block 826. A short connecting rod 829 is hinged to the middle of the long connecting rod 828. The other end of the short connecting rod 829 is hinged to the fixed block 827. A limiting groove is provided outside the fixed cylinder 823. A moving groove is provided on the sliding cylinder 824. A transmission rod 8261 is provided on the sliding block 826. One end of the transmission rod 8261 passes through the limiting groove and extends into the moving groove.

[0022] When the material handling telescopic cylinder is working, it can drive the sliding cylinder to move up and down. Through the transmission rod, the sliding block can move up and down, thereby driving one end of the long connecting rod to move up and down. Through the short connecting rod, the contact parts can be expanded or contracted.

[0023] The trolley fixing assembly 830 includes a limiting rod 831 for limiting the position of the automatic trolley and a clamping assembly for fixing the automatic trolley 900. Two limiting rods 831 extending to the left and right are provided at the wheels of each row of automatic trolleys. A guide section is provided on the left side of the limiting rod 831 to facilitate the entry of the automatic trolley. The clamping assembly is located at the right end of the limiting rod 831.

[0024] The clamping assembly includes a limiting seat 832 and a clamping seat 833. A clamping cylinder 834 is disposed on the clamping seat 833, and a clamping block 835 is disposed on the clamping cylinder 834. When the automatic carriage 900 moves into position, the clamping cylinder 834 operates, causing the clamping block 835 to change from a horizontal state to a vertical state, thereby clamping the automatic carriage 900 onto the clamping seat 833 from the left side. Preferably, both the clamping seat 833 and the clamping block 835 are provided with buffer blocks 836. The connection between the clamping cylinder and the clamping block is prior art.

[0025] The rubber sleeve positioning assembly 840 includes a rubber sleeve positioning seat 841. A bidirectional moving assembly 842 extends forward and backward on the rubber sleeve positioning seat 841. Two bidirectional moving blocks 843 are provided on the bidirectional moving assembly 842, and the two bidirectional moving blocks 843 can move towards each other synchronously or in opposite directions. Each bidirectional moving block 843 is provided with a centering clamping assembly that can clamp the rubber sleeve. The bidirectional moving assembly can adopt the motor screw structure in the prior art, and the screw is provided with threads with opposite directions at both ends.

[0026] The centering clamping assembly includes clamping seats 844 vertically arranged on corresponding bidirectional moving blocks 843. Each clamping seat 844 has two sets of moving shafts 845 extending forward and backward at left and right intervals, and the moving shafts 845 on the two clamping seats 844 are arranged opposite each other. A clamping moving block 846 is provided at the end of each set of moving shafts 845 away from the corresponding clamping seat, and the clamping moving block 846 can move back and forth on the corresponding moving shaft 845. An adjusting spring 847 is sleeved on the moving shaft 845 and located between the clamping moving block 846 and the clamping seat 844. V-blocks 848 are hinged to both the upper and lower ends of the clamping moving block 846, and the middle part of the V-block 848 is hinged to the clamping moving block 846. Vertically extending clamping rollers 849 are hinged to the two ends of the two vertically opposite V-blocks 848. There are two of each set of moving shafts at a vertical interval. By adjusting the spring settings, clamping can be adapted to situations where there are errors in the outer roundness of the rubber sleeve. By using V-blocks and two clamping rollers, clamping of rubber sleeves with different diameters can be achieved.

[0027] The working process of the automatic feeding device is as follows:

[0028] Once the automatic trolley, carrying the rubber sleeve, moves into the three-axis moving assembly and is secured by the trolley fixing assembly, the three-axis moving assembly, carrying the material handling tensioner, moves into the corresponding rubber sleeve. Then, the material handling telescopic cylinder operates, causing the contact element to bulge the rubber sleeve, thereby achieving material handling. Next, the three-axis moving assembly drives the rubber sleeve into the rubber sleeve positioning assembly. Then, the bidirectional moving assembly operates, causing the clamping roller to automatically center and clamp the rubber sleeve from the outside. Then, the material handling telescopic cylinder operates, causing the material handling tensioner to retract. Finally, the three-axis moving assembly drives the material handling tensioner to move out of the rubber sleeve located in the rubber sleeve positioning assembly.
