Abstract
Description
Technical Field
[0001] This utility model relates to the field of paint bucket processing, and in particular to a device for correcting deformed paint buckets. Background Technology
[0002] Paint drums are containers used to hold paint, typically made of high-quality metals such as steel, which are corrosion-resistant, have good sealing properties, and are heat-resistant. Since these drums are mainly made of galvanized iron sheets with a rust-preventive coating, dents may appear on their surface after production due to collisions during transport or other mishandling during manufacturing. Therefore, straightening devices are needed to smooth out these dents.
[0003] The existing technology still has the following problems when used:
[0004] Although the dent can be corrected by a two-roller or three-roller rolling machine, the iron barrel has a reinforcing ring on its surface. After the dent is corrected by the rolling machine, the reinforcing ring will be squeezed out. If the reinforcing ring is not repressed, the surface strength of the iron barrel is not easy to guarantee. Therefore, in order not to affect the reinforcing ring, this application proposes a deformable iron barrel correction device. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a deformable iron barrel straightening device, which can solve the following technical problems: Although the depression can be straightened by a two-roller or three-roller rolling machine, since the iron barrel surface has a reinforcing ring, after the depression on the iron barrel surface is straightened by the rolling machine, the reinforcing ring will also be squeezed out. If the reinforcing ring is not repressed, the surface strength of the iron barrel is not easy to guarantee.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a deformed iron barrel straightening device, including a base frame, a support structure provided on the top surface of the base frame, two support roller shafts extending from the support structure below and a pressure roller shaft extending from the support structure above, a movable pressure roller fixed to the outer side of the pressure roller shaft, the other end of the support roller shaft being supported by a bearing seat, a fixed support roller fixed to the outer side of the support roller shaft near the bearing seat, a movable support roller sleeved on the outer side of the support roller shaft, a placement groove opened on the side of the fixed support roller facing the movable support roller, a spring sleeved on the outer side of the support roller shaft between the placement groove and the movable support roller, and a movable push plate provided on the top surface of the base frame, so that the movable support roller and the fixed support roller can be spliced into a whole or separated into two parts through the cooperation of the push plate and the spring.
[0007] As a preferred embodiment of this utility model, a guide bar is fixed on the outer side of the support roller shaft, and a transverse guide groove that cooperates with the guide bar is opened on the inner side of the movable support roller.
[0008] As a preferred embodiment of this utility model, the support structure includes a first support side plate and a second support side plate fixed to the top surface of the base frame. The support roller shaft passes through the first support side plate and the second support side plate. Vertical guide grooves are provided on the sides of the second support side plate and the first support side plate. Moving blocks are provided inside the vertical guide grooves. The pressure roller shaft is inserted into the two moving blocks. An adjusting bolt is rotatably connected to the top of the moving block. The adjusting bolt extends upward and screws into the first support side plate and the second support side plate respectively.
[0009] In a preferred embodiment of this invention, the width of the moving block is the same as the width of the vertical guide groove.
[0010] As a preferred technical solution of this utility model, the top surface of the base frame is symmetrically provided with a first fixing block and a second fixing block, the first fixing block is movably connected to the first support side plate with an adjusting screw, and the second fixing block is fixed to the first support side plate with a guide rod.
[0011] In a preferred embodiment of this invention, the push plate is sleeved on the outside of the guide rod, and the push plate is threadedly connected to the adjusting screw.
[0012] As a preferred embodiment of the present invention, the side of the second support side plate is provided with two driven gears connected to the shaft of the support roller, and the side of the second support side plate is provided with a drive gear that meshes with the two driven gears.
[0013] Compared with the prior art, the beneficial effects that this utility model can achieve are:
[0014] 1. By designing a movable support roller that can move outside the support roller shaft, the distance between the fixed support roller and the movable support roller can be changed. The spring force can be used to keep the distance between the movable support roller and the fixed support roller continuously maintained. The position of the movable support roller can be changed by a push plate. This is used to merge and separate the movable support roller and the fixed support roller. Thus, the distance between the movable support roller and the fixed support roller can be changed to place the iron barrel rib ring and prevent the rib ring from being flattened.
[0015] 2. By designing a guide strip set on the outside of the support roller shaft and a transverse guide groove located inside the movable support roller, the movable support roller can move along the axial direction of the support roller shaft through the cooperation of the transverse guide groove and the guide strip, and can be driven to rotate by the support roller shaft.

A first support side plate 7 and a second support side plate 9 are provided on the top surface of the base frame 1. Two support roller shafts 10 are threaded through both the first and second support side plates 7 and 9, respectively. The support roller shafts 10 are symmetrically arranged, and extend a certain distance after passing through the second support side plate 9. A driven gear 19 is sleeved on the outer side of the support roller shaft 10, and a drive gear 20 that meshes with the two driven gears 19 is provided on the outer side of the second support side plate 9. The drive gear 20 is connected to an external motor. A vertical guide groove 6 is provided on the side of the first support side plate 7 and the second support side plate 9. A movable block 5 is provided on the inner side of the vertical guide groove 6. The width of the movable block 5 is the same as the width of the vertical guide groove 6. The pressure roller shaft 4 is inserted into the two movable blocks 5. An adjusting bolt 8 is rotatably connected to the top of the movable block 5. The adjusting bolt 8 extends upward and is screwed into the first support side plate 7 and the second support side plate 9 respectively. By rotating the adjusting bolt 8, the height of the movable block 5 is changed, thereby changing the height of the pressure roller shaft 4 passing through the movable block 5. A movable pressure roller 3 is fixed on the outer side of the pressure roller shaft 4.
[0025] like Figures 1-4 As shown, the support roller shaft 10 passes through the first support side plate 7 and connects to the bearing seat 2. The bearing seat 2 is fixed on the top surface of the base frame 1. A fixed support roller 16 is fixed at one end of the support roller shaft 10 that contacts the bearing seat 2. A movable support roller 13 is sleeved on the outside of the support roller shaft 10. A transverse guide groove 22 is provided on the inner side of the movable support roller 13. A guide strip 23 is fixed on the outside of the support roller shaft 10. The transverse guide groove 22 and the guide strip 23 cooperate to enable the movable support roller 13 to move along the axial direction of the support roller shaft 10. The rotation of the support roller shaft 10 is transmitted to the movable support roller 13 through the cooperation of the transverse guide groove 22 and the guide strip 23. A placement groove 21 is provided on the side of the fixed support roller 16 facing the movable support roller 13. A spring 14 is sleeved on the outside of the support roller shaft 10. The spring 14 is located inside the placement groove 21. The length of the fixed support roller 16 is the same as the length from the bottom of the iron bucket to the bone ring, and the length of the movable support roller 13 is the same as the length from the mouth of the iron bucket to the bone ring.
[0026] like Figure 5 As shown, a movable push plate 12 is provided on the top surface of the base frame 1. The push plate 12 can push the movable support roller 13 to move. The connection between the push plate 12 and the cylinder fixed on the top surface of the base frame 1 is not shown in this embodiment.
[0027] like Figures 1-4As shown, the top surface of the base frame 1 is symmetrically provided with a first fixing block 15 and a second fixing block 17. An adjusting screw 11 is movably connected between the first fixing block 15 and the first support side plate 7. A guide rod 18 is fixed between the second fixing block 17 and the first support side plate 7. A push plate 12 is sleeved on the outside of the guide rod 18. The push plate 12 is threadedly connected to the adjusting screw 11, so that the moving support roller 13 is moved by the rotation of the adjusting screw 11.
[0028] Specific working principle:
[0029] When straightening a deformed paint bucket, the adjusting screw 11 is rotated, which drives the push plate 12 to move. At the same time, the spring 14 pushes the movable support roller 13 to contact the push plate 12. By changing the distance of the push plate 12, the position between the movable support roller 13 and the fixed support roller 16 can be changed. The bucket is placed on the outside of the movable pressure roller 3, and the outside of the bucket is placed on the outside of the fixed support roller 16. The rib of the fixed support roller 16 is placed between the movable support roller 13 and the fixed support roller 16. By adjusting the height of the movable block 5, the movable pressure roller 3 is pressed against the inner wall of the bucket. The drive gear 20 drives the support roller shaft 10 to rotate, which in turn drives the fixed support roller 16 and the movable support roller 13 to rotate, thereby rotating the bucket to achieve the straightening of the deformed bucket.
