DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example:

[0043] See also Figure 1-Figure 5 The present invention provides a technical solution: a spot welding device for a fire hose reel basket, comprising a base plate 1, a transmission belt 2, a first support frame 4 and a welding frame 7 are respectively arranged above the base plate 1, a placement groove 33 is opened above the welding frame 7, a basket connecting plate 8 is placed in the placement groove 33, flower basket side plates 9 are placed at equal intervals on the transmission belt 2, an intermittent feeding mechanism is arranged on the side of the transmission belt 2, a clamping mechanism is arranged in the middle of the first support frame 4, and a welding gun 13 is arranged on the first support frame 4, and a rotating mechanism is arranged below the welding frame 7.

[0044] The rotating mechanism rotates the welded flower basket connecting plate 8, and moves the welded flower basket side plate 9 from the first position to the second position. The rotating mechanism returns to its original position under the drive of the transmission mechanism, and performs the next rotation of the flower basket connecting plate 8. The first position of the flower basket side plate 9 is located at the clamping block 22, and the second position of the flower basket side plate 9 is located at the position of the flower basket side plate 9 after the flower basket connecting plate 8 rotates 90°.

[0045] In this embodiment, the first support plate 3, the second support plate 5 and the second support frame 6 are fixedly installed on the top of the base plate 1, and the first rotating column 14 is movably installed on the side of the first support plate 3. The first rotating column 14 and the outer side are respectively fixedly installed with a rotating cam column 16 and a transmission wheel 17. The symmetrical sides of the rotating cam column 16 are provided with protruding blocks. When rotating, the rotating cam column 16 will contact the movable column 11 and the pressure plate 15 in stages, that is, the rotating cam column 16 does not contact the movable column 11 and the pressure plate 15 at the same time, and a belt 10 is provided on the outer side of the transmission wheel 17.

[0046] A motor 40 is fixedly mounted on the side of the first support plate 3, and a reducer is connected to the output shaft end of the motor 40, and is fixedly connected to one end of the first rotating column 14 through the reducer. The motor 40 can provide power for the intermittent discharge mechanism, the clamping mechanism and the rotating mechanism.

[0047] A sensor 23 is fixedly installed on the first support frame 4. The sensor 23 can adjust the moving distance of the flower basket side plate 9 on the transmission belt 2, and the sensor 23 can control the movement state of the transmission belt 2. When the flower basket side plate 9 moves from the intermittent discharge mechanism to the bottom of the first support frame 4, the sensor 23 will stop the transmission belt 2 from moving, that is, the flower basket side plate 9 moves to the side of the flower basket connecting plate 8 and contacts with the flower basket connecting plate 8. The sensor 23 controls the distance of the flower basket side plate 9 at the first adjusting rod 19 on the transmission belt 2 to the flower basket side plate 9 at the clamping block 22, which is equal to the time it takes for the first rotating column 14 to rotate one circle.

[0048] In this embodiment, a first connecting rod 18 is fixedly installed on one side of the first support plate 3, and the outer side of the first connecting rod 18 is movably connected to the intermittent discharge mechanism. The intermittent discharge mechanism allows the flower basket side plate 9 on the transmission belt 2 to indirectly pass through the intermittent discharge mechanism to prevent the two flower basket side plates 9 at the ends of the transmission belt 2 in the traveling direction from sticking together.

[0049] In this embodiment, the intermittent discharge mechanism includes a movable column 11, which is in active contact with a rotating cam column 16. The shape of the movable column 11 is U-shaped, and the two ends of the movable column 11 have different lengths. The two ends of the movable column 11 are respectively fixed with a first adjusting rod 19 and a second adjusting rod 20, and the first adjusting rod 19 and the second adjusting rod 20 are both in contact with the flower basket side panel 9.

[0050] The length of the first adjusting rod 19 is greater than that of the second adjusting rod 20, and the first adjusting rod 19 is located above the second adjusting rod 20. Blocks are fixedly installed on adjacent sides of the first adjusting rod 19 and the second adjusting rod 20, and the two blocks are respectively in contact with two adjacent flower basket side panels 9.

[0051] When the rotating cam column 16 rotates and contacts the movable column 11, the rotating cam column 16 will rotate the movable column 11 around the first connecting rod 18. When the movable column 11 rotates around the first connecting rod 18, the angle is less than 120°. When the rotating cam column 16 drives the movable column 11 to rotate, the movable column 11 will drive the first adjusting rod 19 to move upward, so that the flower basket side plate 9 blocked by the first adjusting rod 19 moves toward the side of the first support frame 4 under the operation of the transmission belt 2. At the same time, the second adjusting rod 20 will move the transmission belt 2 upward. The forward direction is blocked by the flower basket side plate 9 at the rear. When the rotating cam column 16 and the movable column 11 are separated from each other, the first adjusting rod 19 and the second adjusting rod 20 rotate in the opposite direction around the first connecting rod 18 under their own gravity. When the second adjusting rod 20 continues to rotate, it will separate from the first flower basket side plate 9 behind it and move it forward. At the same time, the first adjusting rod 19 rotates to the front of it, so that this flower basket side plate 9 is located between the first adjusting rod 19 and the second adjusting rod 20, so that it can no longer move on the transmission belt 2.

[0052] The motor 41 provides power for the intermittent feeding mechanism, the clamping mechanism and the rotating mechanism. The various mechanisms work together to realize automated production, reduce manual operation links, and greatly improve the production efficiency of the fire hose reel basket.

[0053] The sensor 23 can adjust the moving distance of the flower basket side plate 9 on the transmission belt and control the movement state of the transmission belt 2, ensuring that the flower basket side plate 9 is accurately moved to the specified position for welding, and rotates with the first rotating column 14 to make the production process smoother and more efficient.

[0054] See also Figure 6-Figure 7 , the present invention provides a technical solution: in this embodiment, the clamping mechanism welds the flower basket side plate 9 and the flower basket connecting plate 8 so that the two are tightly fitted to prevent a gap between the flower basket connecting plate 8 and the flower basket side plate 9;

[0055] The clamping mechanism includes a first connecting cylinder 12 and a second connecting cylinder 21, which are connected to each other through a connecting pipe 24. A first compression spring 27 is fixedly installed in the first connecting cylinder 12, and a piston plate 28 is fixedly installed on the other end of the first compression spring 27. A push column 26 is fixedly installed on the other end of the piston plate 28. The other end of the push column 26 passes through the first connecting cylinder 12 and is fixedly installed with a pressure plate 25. The pressure plate 25 is located on the outside of the first connecting cylinder 12, and the pressure plate 25 is in contact with the rotating cam column 16.

[0056] The pressure plate 25 is in a semicircular arc shape. When the pressure plate 25 does not receive any power, the pressure plate 25 will stretch the first compression spring 27 and drive the piston plate 28 to move downward. Both sides of the pressure plate 25 are provided with inclined edges to facilitate the rotating cam column 16 to contact the pressure plate 25, thereby driving the pressure plate 25 to move.

[0057] In this embodiment, a piston column is movably installed inside the second connecting tube 21, and an air bag is fixedly installed. The connecting tube 24 does not contact the air bag, and the piston column is located between the connecting tube 24 and the air bag. The piston column contacts the air bag. A limit block is provided inside the second connecting tube 21. The connecting tube 24 and the piston column are respectively located on both sides of the limit block. The limit block prevents the piston column from directly contacting the inner wall of the side of the second connecting tube 21. The air bag will be squeezed when the piston column drives the clamping block 22 to fix the flower basket side plate 9. After the pressure plate 25 is no longer in contact with the rotating cam column 16, under the action of the first compression spring 27, the gas in the second connecting cylinder 21 will flow back to the first connecting cylinder 12 through the connecting pipe 24, so that the piston column in the second connecting cylinder 21 will return to its original position under the action of the airbag, and the clamping block 22 will be separated from the flower basket side plate 9, and one end of the piston column passes through the second connecting cylinder 21 and is fixedly installed with the clamping block 22, the clamping block 22 is in contact with the flower basket side plate 9, and fixes the flower basket side plate 9.

[0058] When the rotating cam column 16 rotates and contacts the pressure plate 25, the pressure plate 25 will move the piston plate 28 in the first connecting tube 12 through the pushing column 26, and squeeze the first compression spring 27. At the same time, the movement of the piston plate 28 will squeeze the piston column and the air bag in the second connecting tube 21, and the piston column will drive the clamping block 22 to fix the flower basket side plate 9, so as to ensure that the flower basket side plate 22 is in an upright state when being welded with the flower basket connecting plate 8, and prevent the flower basket side plate 9 from falling down; on the contrary, after the pressure plate 25 is separated from the rotating cam column 16, the squeezed first compression spring 27 and the air bag will drive the clamping block 22 to separate from the flower basket side plate 9, so as to facilitate the rotation of the welded flower basket side plate 9 and the flower basket connecting plate 8 around the welding frame 7, so as to facilitate the welding of the next flower basket side plate 9 and the flower basket connecting plate 8.

[0059] The clamping mechanism can make the flower basket side plate and the flower basket connecting plate fit tightly during welding to prevent a gap between the two. The pressure plate cooperates with the rotating cam column, and through the action of the push column, piston plate, first compression spring and other components, the piston column drives the clamping block to fix the flower basket side plate, ensuring that the flower basket side plate remains upright during welding to prevent tipping, thereby improving the welding quality.

[0060] The anti-tilt plate on the side of the welding frame can prevent the side plate of the flower basket from tilting on the transmission belt due to inertia, ensuring that the side plate of the flower basket fits better with the side of the flower basket connecting plate. With the cooperation of the clamping block, it is convenient for the welding gun to perform welding work, thereby increasing the yield rate of the fire reel flower basket.

[0061] The movable column, the first adjusting rod and the second adjusting rod in the intermittent discharge mechanism cooperate with the rotating cam column to enable the flower basket side plate on the transmission belt to intermittently pass through the intermittent discharge mechanism, effectively preventing the two flower basket side plates at the end of the transmission belt in the direction of travel from sticking together, thereby ensuring the smooth progress of the production process.

[0062] See also Figure 8-Figure 13 The present invention provides a technical solution: in this embodiment, the rotating mechanism includes a rotating cylinder 15 and an adjusting column 29, the end of the adjusting column 29 is in contact with the flower basket side plate 9, the rotating mechanism is located below the welding frame 7, a fixed column 36 is fixedly installed inside the rotating cylinder 15, and a sliding block 37 and a second compression spring 38 are movably installed on the outer side of the fixed column 36, the bottom end of the sliding block 37 is fixedly connected to the second compression spring 38, the side of the sliding block 37 is fixedly connected to the adjusting column 29, and a sliding cavity 39 matching the adjusting column 29 is opened through the interior of the rotating cylinder 15.

[0063] In this embodiment, the second support plate 5 has a second rotating column 31 and a third rotating column 34 movably mounted inside, a transmission wheel 17 is fixedly mounted on the end of the second rotating column 31, and the other end of the second rotating column 31 has only a driving bevel gear 41 fixedly mounted thereon. The top end of the third rotating column 34 is fixedly connected to the bottom end of the rotating cylinder 15, and a driven bevel gear 35 is fixedly mounted on the bottom end of the third rotating column 34. The driving bevel gear 41 is meshedly connected with the driven bevel gear 35, and the shape and size of the driving bevel gear 41 and the driven bevel gear 35, as well as the number of teeth of the driving bevel gear 41 and the driven bevel gear 35 are the same.

[0064] When the first rotating column 14 rotates, the second rotating column 31 will be driven to rotate through the transmission wheel 17 and the belt 10. The rotation of the second rotating column 31 will drive the third rotating column 34 to rotate through the active bevel gear 41 and the driven bevel gear 35. When the third rotating column 34 rotates, it will drive the rotating cylinder 15 to rotate. The adjusting column 29 located in the rotating cylinder 15 will rotate together with the rotating cylinder 15. When the adjusting column 29 rotates, it will pass through the inclined surface 32, and the adjusting column 29 will move downward in the sliding cavity 39 in the rotating cylinder 15. During the downward movement of the adjusting column 29, the second compression spring 38 will be squeezed by the sliding block 37. After the adjusting column 29 moves to the bottom of the welding frame 7, it will rotate through the bottom of the welding frame 7 and return to its original position through the other side of the inclined surface 32, that is, it will contact the next welded flower basket side plate 9 and drive the welded flower basket side plate 9 to rotate again, and the welded flower basket side plate 9 and the flower basket connecting plate 8 will be rotated around the welding frame 7 over and over again.

[0065] In this embodiment, the rotating cylinder 15 is located above the second support plate 5 and below the welding frame 7, and the top end of the rotating cylinder 15 is in sliding contact with the bottom end of the welding frame 7. An inclined surface 32 is provided below the welding frame 7, and the adjusting column 29 is in contact with the inclined surface 32. The rotating cylinder 15 does not drive the welding frame 7 to rotate when it rotates, nor will it be affected by the welding frame 7. At the same time, a rotating groove matching the top end of the rotating cylinder 15 is provided at the bottom end of the welding frame 7, so that the rotating cylinder 15 will not tilt to one side due to speed reasons when it rotates, thereby ensuring that the rotating cylinder 15 always maintains a stable state when it rotates.

[0066] An anti-tilt plate 30 is fixedly installed on the side of the welding frame 7. The anti-tilt plate 30 is located above the adjusting column 29 and below the flower basket connecting plate 8. The anti-tilt plate 30 can prevent the flower basket side plate 9 from tilting due to inertia on the transmission belt 2 when the flower basket side plate 9 moves to the flower basket connecting plate 8, and ensure that the flower basket side plate 9 can better fit with the side of the flower basket connecting plate 8 when it moves to the flower basket connecting plate 8. Under the cooperation of the clamping block 22, the flower basket side plate 9 is ensured to be tightly fitted with the side of the flower basket connecting plate 8, which is convenient for the welding gun 13 to perform welding work, and also increases the yield rate of the fire reel flower basket.

[0067] In this embodiment, the angle of the inclined surface 32 is 90°. The adjusting column 29 is located above the transmission belt 2 and below the anti-tilt plate 30. After the adjusting column 29 rotates 90° with the rotating cylinder 15, the welded flower basket side plate 9 and the flower basket connecting plate 8 are rotated 90° around the welding frame 7. The adjusting column 29 will be affected by the inclined surface 32 and move downward through the inclined surface 32 and separate from the rotated flower basket side plate 9. Under the continuous rotation of the rotating cylinder 15, the adjusting column 29 slides on the bottom end of the welding frame 7. When the adjusting column 29 rotates to the other end of the inclined surface 32, it returns to its original position through the action of the inclined surface 32 and contacts the next flower basket side plate 9 again, and rotates the next welded flower basket side plate 9 and the flower basket connecting plate 8. The adjusting column 29 will rotate repeatedly under the welding frame 7 and transport the flower basket side plates 9 one by one to the flower basket connecting plate 8 for welding, thereby obtaining a complete fire hose reel flower basket.

[0068] The top end of the rotating cylinder 15 is in sliding contact with the bottom end of the welding frame 7. A rotating groove is provided at the bottom end of the welding frame 7, and structures such as an inclined surface 32 and an anti-tilt plate 30 are provided to ensure that the rotating cylinder 15 always remains in a stable state during rotation, will not drive the welding frame 7 to rotate, and will not be affected by the welding frame 7, thereby ensuring the stability and reliability of the device.

[0069] The working principle of this embodiment is as follows: the rotating cylinder 15 rotates, and the adjusting column 29 located in the rotating cylinder 15 will rotate together with the rotating cylinder 15. When the adjusting column 29 rotates, it will pass through the inclined surface 32, and the adjusting column 29 will move downward in the sliding cavity 39 in the rotating cylinder 15. During the downward movement of the adjusting column 29, the second compression spring 38 will be squeezed by the sliding block 37. After the adjusting column 29 moves to the bottom of the welding frame 7, it will rotate through the bottom of the welding frame 7 and return to its original position through the other side of the inclined surface 32, that is, it will contact the next welded flower basket side plate 9, and drive the welded flower basket side plate 9 to rotate again, and the welded flower basket side plate 9 and the flower basket connecting plate 8 will be rotated around the welding frame 7 over and over again.

[0070] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
