Description

Technical Field

[0001] The utility model relates to the technical field of can making, in particular to a sizing and stabilizing device. Background Art

[0002] The current common canning process involves using shears to cut coils into rectangular sheets, then rolling the sheets into cylindrical can bodies. The seams along the edges of the sheets are then welded. In daily production, automatic welders are typically used for this purpose. However, these machines lack effective sizing mechanisms designed for round cans, often resulting in uneven welds, low-quality welds, and out-of-round can bodies.

[0003] To address these issues, sizing mechanisms that can move with the can body have emerged. For example, a single-plate sizing mechanism for a resistance welding can body machine, disclosed on June 29, 2016, with publication number CN205342197U, primarily comprises a fixed frame and rollers. A first roller assembly, a second roller assembly, and a third roller assembly are provided on the front and rear sides of the fixed frame. The rollers of the first, second, and third roller assemblies form a through hole through which the can body can pass, and the outer surfaces of the rollers are arc-shaped. However, in actual use, when the can body extends from the back to the front into the sizing mechanism, the sizing mechanism can only constrain the rear portion of the can body in the initial stage. Given that the can body typically has a certain length, before the plate is welded, its two edges will separate from each other due to their own elastic force, resulting in an increase in the distance between the two edges in the front portion of the can body and an overlap of the two edges in the rear portion. This situation will cause the weld to shift during welding, making the tank body appear to be a frustum with a smaller back and a larger front after welding, which seriously affects the quality of the tank body. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a sizing and stabilizing device, which can continuously and stably transport the plate along the shape of the can body to be rolled, without the occurrence of weld deviation, and effectively ensure the welding quality.

[0005] In order to solve the above technical problems, the technical solutions adopted are as follows:

[0006] A sizing and stabilizing device comprises a frame and a plurality of roller mechanisms, wherein the frame is provided with a through hole, and each roller mechanism is arranged at the edge of the through hole along the circumference of the through hole. The device is characterized in that: it also comprises a plurality of guide sizing mechanisms, each guide sizing mechanism is arranged at the edge of the through hole along the circumference of the through hole, and the guide sizing mechanism is located in front of the roller mechanism; the guide sizing mechanism comprises a plurality of sizing wheels, and each sizing wheel in the same guide sizing mechanism is arranged in sequence from front to back along the axial direction of the through hole.

[0007] When the above-mentioned sizing and sizing stability device welds the tank body, the contour formed by each guiding and sizing mechanism matches the contour formed by each roller mechanism, and each sizing wheel together forms a cylindrical contour; in the initial stage, the rolled sheet enters from the contour formed by each guiding and sizing mechanism. At this time, the sizing wheels in each guiding and sizing mechanism respectively contact the rear part of the side wall of the sheet. The guiding and sizing mechanism can guide and pre-size the sheet, making the cylindrical shape formed by the sheet match the required shape of the tank body; as the sheet continues to extend into the through-hole, the rear part of the side wall of the sheet begins to contact each roller mechanism, and at the same time the middle part of the side wall of the sheet contacts the guiding and sizing mechanism. At this time, the guiding and sizing mechanism can continue to guide and maintain the shape of the middle and front parts of the sheet, keeping the rear part of the sheet stable. Therefore, when welding the seam at the beginning, due to the restriction of the guiding and sizing mechanism, the middle and front parts of the sheet can maintain the same diameter and shape as the rear part of the sheet, and there will be no situation where the two edges of the middle and front parts of the sheet are not restricted and loosen and separate, which affects the welding of the rear part of the sheet and the weld seam cannot smoothly extend along the side seam of the joint; and so on until the entire coil of sheet is welded. This sizing and sizing stability device can ensure that the sheet can be continuously and stably conveyed along the shape of the tank body to be rolled during the entire process of welding the sheet into the tank body, without the situation of the weld seam deviating, effectively ensuring the welding quality.

[0008] In the above front-back direction, it is determined according to the position where the tank body enters. The position that the tank body passes through first when entering is the front, and the position that it passes through later is the back.

[0009] The above-mentioned roller mechanism can adopt the same structure as the roller unit in Patent CN205342197U.

[0010] In a preferred solution, the guiding and sizing mechanism further includes a guiding frame. The guiding frame is arranged along the circumference of the through-hole at the edge of the through-hole and is perpendicular to the through-hole. Each sizing wheel is rotatably installed on the corresponding guiding frame along the length direction of the guiding frame. The guiding frame, as the support frame for installing the sizing wheels, can arrange the sizing wheels in the same guiding and sizing mechanism in sequence.

[0011] In a further preferred solution, the guiding and sizing mechanism further includes an adjustment component capable of adjusting the position of the guiding frame in the inner-outer direction. The guiding frame is movably arranged on the frame through the adjustment component in the inner-outer direction. According to the different diameters of the tank bodies to be welded, the guiding frame can be adjusted through the adjustment component, thereby changing the position of the sizing wheels, so that each sizing wheel together forms a cylindrical contour with adjustable diameter (similarly, each roller mechanism can also be adjusted to make the contour formed by each guiding and sizing mechanism match the contour formed by each roller mechanism), which is applicable to various tank bodies with different diameters. In the above inner-outer direction, the position close to the axis of the through-hole is the inner, and the position far from the axis of the through-hole is the outer.

[0012] In a further preferred embodiment, the adjusting assembly includes a fixed seat, at least one rotating rod and at least one nut. The fixed seat is mounted on the frame. At least one through hole corresponding in position is respectively formed in the fixed seat and the guiding frame. The number of the rotating rods, nuts and through holes is the same and they correspond one by one. An external thread matching the nut is provided at the outer end of the side wall of the rotating rod. An adjusting head is provided at the inner end of the rotating rod. The rotating rod sequentially passes through the through holes in the guiding frame and the fixed seat and is in threaded connection with the nut, and the adjusting head is clamped outside the through hole of the guiding frame. The rotating rod is perpendicular to the axis of the through hole; the nut is fixedly connected to the fixed seat. During adjustment, the rotating rod can be rotated through the adjusting head, and by adjusting the depth of the cooperation between the rotating rod and the nut, the adjusting head can be used to push the guiding frame to move, so as to realize the internal and external adjustment of the guiding frame.

[0013] In a still further preferred embodiment, the rotating rod includes an adjusting column and an adjusting bolt. A threaded hole matching the adjusting bolt is formed in the inner end face of the adjusting column. The inner end of the adjusting column extends into the through hole of the guiding frame and is in threaded connection with the adjusting bolt through the threaded hole; a limiting step is provided on the side wall of the adjusting column. The size of the limiting step is larger than the through hole of the guiding frame and matches the size of the through hole of the fixed seat; the adjusting bolt constitutes the adjusting head, and the external thread of the rotating rod is provided at the outer end of the side wall of the adjusting column. During adjustment, the adjusting column can be rotated by rotating the adjusting bolt, so as to adjust the guiding frame; at the same time, the limiting step can hold the position of the guiding frame to prevent the guiding frame from moving outwards along the adjusting column when stressed.

[0014] In a further preferred embodiment, the sizing wheels in the same guiding and sizing mechanism are divided into two groups. The two groups of sizing wheels are respectively rotatably mounted on both sides of the corresponding guiding frame and arranged along the length direction of the guiding frame. Dividing the sizing wheels into two groups can make the arrangement more dense. At the same time, in the case of providing the adjusting assembly, it can also avoid the sizing wheels blocking the adjusting assembly during adjustment, making the position adjustment more convenient. The way of mounting the sizing wheels on the guiding frame can be to form through holes in the sizing wheels and form threaded holes on the side wall of the guiding frame, and the bolts pass through the through holes and are in threaded connection with the threaded holes.

[0015] The beneficial effect of the present invention is that this sizing and fixing stability device can ensure that the tank body enters more smoothly and the entering angle is accurate without deviation when the tank body enters before welding, thus ensuring the welding quality.

[0021] The following further describes the present utility model in conjunction with the accompanying drawings and specific embodiments:

[0022] As Figures 1-5 shown, a sizing and stabilizing device includes a frame 1, a plurality of roller mechanisms 2, and a plurality of guiding and sizing mechanisms 3. A through hole 101 is provided on the frame 1. Each roller mechanism 2 is arranged along the circumference of the through hole 101 at the edge of the through hole 101. Each guiding and sizing mechanism 3 is arranged along the circumference of the through hole 101 at the edge of the through hole 101, and the guiding and sizing mechanism 3 is in front of the roller mechanism 2. The guiding and sizing mechanism 3 includes a plurality of sizing wheels 301. The sizing wheels 301 in the same guiding and sizing mechanism 3 are arranged in sequence from front to back along the axial direction of the through hole 101.

[0023] When the above-mentioned sizing and stabilizing device welds the tank body, the contour formed by each guiding and sizing mechanism 3 matches the contour formed by each roller mechanism 2, and each sizing wheel 301 together forms a cylindrical contour. In the initial stage, the rolled plate enters from the contour formed by each guiding and sizing mechanism 3. At this time, the sizing wheels 301 in each guiding and sizing mechanism 3 are respectively in contact with the rear part of the side wall of the plate. The guiding and sizing mechanism 3 can play a role in guiding and pre-sizing the plate, so that the cylindrical shape formed by the plate matches the required shape of the tank body. As the plate continues to enter the through hole 101, the rear part of the side wall of the plate begins to contact each roller mechanism 2, and at the same time, the middle part of the side wall of the plate contacts the guiding and sizing mechanism 3. At this time, the guiding and sizing mechanism 3 can continue to play a role in guiding and maintaining the shape of the middle and front parts of the plate, so that the rear part of the plate remains stable. Therefore, when welding the seam at the rear part of the plate, due to the restriction of the guiding and sizing mechanism 3 on the middle and front parts of the plate, the middle and front parts of the plate can maintain the same diameter and shape as the rear part of the plate, and there will be no situation where the two edges of the middle and front parts of the plate are not restricted and loosen and separate, resulting in an impact on the welding of the rear part of the plate and the weld seam cannot smoothly extend along the side seam of the joint. By analogy, until the entire coil of plate is welded. This sizing and stabilizing device can ensure that the plate can be continuously and stably conveyed along the shape of the tank body to be rolled during the entire process of welding the plate into the tank body, and there will be no deviation of the weld seam, effectively ensuring the welding quality.

[0024] In the above front - rear direction, depending on the position where the tank body enters, the position passed first when the tank body enters is the front, and the position passed later is the rear.

[0025] The above - mentioned roller mechanism 2 can adopt the same structure as the roller unit in Patent CN205342197U.

[0026] The guiding and sizing mechanism 3 further includes a guiding frame 302. The guiding frame 302 is arranged along the circumferential direction of the through - hole 101 at the edge of the through - hole 101, and the guiding frame 302 is perpendicular to the through - hole 101. Each sizing wheel 301 is rotatably installed on the corresponding guiding frame 302 along the length direction of the guiding frame 302. The guiding frame 302, as the supporting frame for installing the sizing wheels 301, can make the sizing wheels 301 in the same guiding and sizing mechanism 3 arranged in sequence.

[0027] The guiding and sizing mechanism 3 further includes an adjusting component 303 capable of adjusting the position of the guiding frame 302 in the inner - outer direction. The guiding frame 302 is movably arranged on the frame 1 through the adjusting component 303. According to the different - diameter tank bodies to be welded, the guiding frame 302 can be adjusted through the adjusting component 303, so as to change the position of the sizing wheels 301, making each sizing wheel 301 jointly form a cylindric - shaped contour with adjustable diameter (similarly, each roller mechanism 2 can also be adjusted so that the contour enclosed by each guiding and sizing mechanism 3 is consistent with the contour enclosed by each roller mechanism 2), which is applicable to tank bodies of various different diameters. In the above inner - outer direction, the position close to the axis of the through - hole 101 is the inner, and the position far from the axis of the through - hole 101 is the outer.

[0028] The adjusting component 303 includes a fixed seat 3031, two rotating rods 3032 and two nuts 3033. The fixed seat 3031 is installed on the frame 1. Two through - holes 4 corresponding in position are respectively opened on the fixed seat 3031 and the guiding frame 302. The rotating rods 3032, nuts 3033 and through - holes 4 correspond one by one. The outer end of the side wall of the rotating rod 3032 is provided with an external thread matching the nut 3033, and the inner end of the rotating rod 3032 is provided with an adjusting head. The rotating rod 3032 passes through the through - holes 4 on the guiding frame 30 and the fixed seat 3031 in sequence and is threadedly connected with the nut 3033, and the adjusting head is clamped outside the through - hole 4 of the guiding frame 302. The rotating rod 3032 is perpendicular to the axis of the through - hole 101; the nut 3033 is fixedly connected with the fixed seat 3031. During adjustment, the rotating rod 3032 can be rotated through the adjusting head, and by adjusting the depth of the cooperation between the rotating rod 3032 and the nut 3033, the adjusting head can push the guiding frame 302 to move, realizing the inner - outer adjustment of the guiding frame 302.

[0029] The rotating rod 3032 includes an adjusting column 30321 and an adjusting bolt 30322. A threaded hole matching the adjusting bolt 30322 is formed in the inner end face of the adjusting column 30321. The inner end of the adjusting column 30321 extends into the through hole 4 of the guide frame 302 and is threadedly connected to the adjusting bolt 30322 through the threaded hole. A limiting step 303211 is provided on the side wall of the adjusting column 30321. The size of the limiting step 303211 is larger than the through hole 4 of the guide frame 302 and matches the size of the through hole 4 of the fixed seat 3031. The adjusting bolt 30322 constitutes an adjusting head, and the external thread of the rotating rod 3032 is provided at the outer end of the side wall of the adjusting column 30321. During adjustment, the adjusting column 30321 can be driven to rotate by rotating the adjusting bolt 30322, thereby adjusting the guide frame 302. At the same time, the limiting step 303211 can hold the position of the guide frame 302 to prevent the guide frame 302 from moving outward along the adjusting column 30321 when stressed.

[0030] The sizing wheels 301 in the same guiding and sizing mechanism 3 are divided into two groups. The two groups of sizing wheels 301 are respectively rotatably installed on both sides of the corresponding guide frame 302 and arranged along the length direction of the guide frame 302. Dividing the sizing wheels 301 into two groups can make the arrangement more dense. At the same time, in the case of setting the adjusting assembly 303, it can also avoid the sizing wheels 301 blocking the adjusting assembly 303 during adjustment, making the position adjustment more convenient. The sizing wheels 301 can be installed on the guide frame 302 by forming through holes in the sizing wheels 301 and threaded holes in the side wall of the guide frame 302, and passing bolts through the through holes and threadedly connecting them to the threaded holes.
