Description

Technical Field

[0001] The invention relates to the technical field of tank body processing, in particular to a vacuum frying negative pressure system component processing and welding equipment. Background Art

[0002] Vacuum frying is a food processing technology carried out in an environment below atmospheric pressure. It is mainly used in the production of snack foods such as potato chips and vegetable chips. This technology can complete the frying process at a lower temperature, thereby reducing the amount of oil absorbed by the food, retaining more nutrients, and reducing the production of harmful substances such as acrylamide. In the vacuum frying negative pressure system, the gas and steam generated during the frying process are mainly stored and recovered by a vacuum tank to maintain the vacuum state of the system. The vacuum tank is mainly a horizontally or vertically placed tank body, usually made of stainless steel, and is usually welded with a ventilation pipe for connecting other components in the system. The ventilation pipe is mainly composed of a section of pipe and a flange, and is usually welded to the upper side of the tank body. According to the different placement states of the tank body, the welding area of ​​the tank body can be a spherical surface, an arc surface or a flat surface.

[0003] At present, when performing the above welding operation, the ventilation pipe is mainly moved by hand or by using a clamp to press the lower end of the ventilation pipe into the welding area of ​​the tank body and make the two close to each other, and then the connection between the tank body and the ventilation pipe is welded all around using existing welding equipment (such as a welding gun).

[0004] The above welding process has the following problems: when welding the vent pipe and the tank body, it is necessary to make the welding point of the two in close contact and make the axis of the vent pipe face the specified direction (usually towards the upper side). It is difficult to meet the above welding requirements by manually pressing or using tools to place the vent pipe in the above manner. When placing the vent pipe in the above manner, the limit clamping of the vent pipe is insufficient, so it is easy to have problems such as inaccurate placement of the vent pipe and deviation of the axis of the vent pipe. As a result, it is easy to have the problem of insufficient connection strength between the vent pipe and the tank body after welding due to loose contact between the vent pipe and the tank body, which in turn affects the connection between the vent pipe on the tank body and other components in the system after welding. Secondly, due to the different end faces of the vent pipe welded on the tank body, the difficulty of placing the vent pipe during welding is increased, and it is easy to have the problem that the connection welding point between the vent pipe and the tank body does not meet the requirements, resulting in the inability to use the component.

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] like Figure 1 and Figure 2 As shown, a vacuum frying negative pressure system component processing and welding equipment includes: a T-shaped frame 1, the transverse section of the T-shaped frame 1 is located at the front side of its longitudinal section, a moving unit 2 is fixedly arranged on the rear end face of the longitudinal section of the T-shaped frame 1, and the moving unit 2 is an existing moving device including a moving wheel, and the front end face of the T-shaped frame 1 is provided with two left-right symmetrical rectangular plates 3 that slide forward and backward through a fixed rod extending from the back to the front through an axis, and a connecting rod 30 with an axis from left to right is penetrated through the rectangular plate 3 for sliding left and right, and opposite surfaces of the two connecting rods 30 are fixedly provided with left-right symmetrical rectangular blocks 31.

[0035] like Figure 1 and Figure 2 As shown, the T-shaped frame 1 and the two rectangular blocks 31 are jointly provided with a clamping mechanism 4 for clamping the tank body, the clamping mechanism 4 includes a clamping plate 40, the two rectangular blocks 31 are each provided with a clamping plate 40, the clamping plate 40 is arc-shaped and the two clamping plates 40 are symmetrical on the left and right, and the T-shaped frame 1 is provided with a driving group 41.

[0036] like Figure 2 and Figure 5 As shown, a vertical rod 5 with a vertical axis is fixedly provided on the upper end surface of the rectangular block 31, and a lifting plate 50 is slidably provided on the two vertical rods 5. The lifting plate 50 is driven by an external hydraulic cylinder (not shown in the figure) to move up and down. A clamping group 51 for clamping the ventilation pipe is commonly provided on the two lifting plates 50, and a Z-shaped frame 52 is commonly provided on the lower end surfaces of the two lifting plates 50. A welding part for welding the ventilation pipe is provided on the Z-shaped frame 52, and the welding part includes an existing welding head (not shown in the figure). A guide unit 6 for guiding the welding head for full-circle welding is commonly provided on the two vertical rods, and the guide unit 6 includes two groups of left-right symmetrical plate groups, and the plate group includes two symmetrical and semicircular upper and lower track plates 60.

[0037] It should be noted that before welding, the tank body to which the ventilation pipe needs to be welded is fixed by its own bracket. The welding process of the ventilation pipe on the vertical tank body is taken as an example. During operation, the moving unit 2 first drives the T-shaped frame 1 to move to the rear side of the tank body to which the ventilation pipe needs to be welded, and the driving group 41 works to make the two clamping plates 40 close to the left and right sides of the tank body. Finally, the two clamping plates 40 complete the clamping and fixing of the tank body, which is convenient for subsequent welding operations.

[0038] While performing the above operations, the ventilation pipe is manually placed under the two lifting plates 50, and the clamping group 51 clamps the ventilation pipe through the operation of the driving group 41. At this time, the axis of the ventilation pipe is in line with the axis of the tank body, and then the external hydraulic cylinder works to move the lifting plate 50 downward. The lifting plate 50 presses the ventilation pipe against the center position above the tank body and ensures that the ventilation pipe is in close contact with the tank body. The guide unit 6 makes the moving trajectory of the Z-shaped frame 52 a trajectory composed of the left and right relative track plates 60. The Z-shaped frame 52 is manually moved, and the welding head thereon works. The Z-shaped frame 52 drives the welding head to rotate a full circle to complete the welding operation on the ventilation pipe.

[0039] When welding is required for the ventilation pipe on the transverse tank body, the orientation of the clamping plate 40 is adjusted and the above-mentioned operation is repeated for welding.

[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the clamping mechanism 4 also includes a sliding groove 42. The opposite surfaces of the two rectangular blocks 31 are provided with a sliding groove 42. A sliding column 420 is provided in the sliding groove 42 for sliding left and right. The clamping plate 40 is fixedly provided on the end surface of the sliding column 420 away from the adjacent rectangular plate 3. The clamping plate 40 is fixedly provided with a spring 421 located between the rectangular block 31 and the clamping plate 40 and sleeved on the sliding column 420.

[0041] like Figure 1 and Figure 4 As shown, the clamping mechanism 4 further includes a guide groove 422 , and the front and rear end surfaces and the upper and lower end surfaces of the rectangular block 31 are both provided with guide grooves 422 connected to the sliding groove 42 , and a guide column 423 is fixedly installed on the sliding column 420 .

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, the driving group 41 includes a bidirectional threaded rod 410, and the longitudinal section of the T-shaped frame 1 is rotatably provided with a bidirectional threaded rod 410 whose axis extends from left to right, and the bidirectional threaded rod 410 is connected to an external motor (not shown in the figure), and a driving block 411 is threadedly sleeved on the bidirectional threaded rod 410, and a connecting block 412 is fixedly provided on the end surface of the connecting rod 30 away from the clamping plate 40, and a horizontal rod 413 is fixedly provided on the front end surface of the driving block 411, which slides back and forth and passes through the corresponding connecting block 412.

[0043] It should be noted that when it is necessary to weld the vent pipe to the upper and lower sides of the vertical tank body, the axis of the clamping plate 40 is vertical. During operation, when the mobile unit 2 drives the T-shaped frame 1 to move to the specified position, the two clamping plates 40 are located on both sides of the tank body, and the external motor drives the bidirectional threaded rod 410 to rotate, so that the two driving blocks 411 approach each other, and the driving block 411 drives the connecting rod 30 and the rectangular block 31 thereon to move synchronously. The rectangular block 31 drives the corresponding clamping plate 40 to move and clamp the tank body through the sliding column 420, and the clamping plate 40 stops moving. As the driving block 411 continues to move, the spring 421 is compressed, and the elastic force generated by the compression of the spring 421 causes the clamping plate 40 to press the tank body. Therefore, the two clamping plates 40 cooperate with each other to press the tank body, and in the above process, the T-shaped frame 1 moves left and right adaptively. Finally, through the above method, the axis of the tank body and the two rectangular blocks 31 are located on the same horizontal vertical plane, and the distance between the axis of the tank body and the two rectangular plates 3 is the same, which is convenient for subsequent welding operations.

[0044] When it is necessary to weld the vent pipe to the horizontal tank body, before performing the above-mentioned clamping operation, the clamping plate 40 is manually moved so that the clamping plate 40 drives the sliding column 420 and the guide column 423 to move synchronously, and the guide column 423 gradually withdraws from the guide groove 422, and the clamping plate 40 is rotated. The clamping plate 40 is rotated so that the axis of the clamping plate 40 is horizontal, and the clamping plate 40 and the guide column 423 are reset so that the guide column 423 is stuck in the two guide grooves 422 on the upper and lower sides, completing the state switching of the clamping plate 40, so as to adapt to the vent pipe welding operation of the tank body in different states in the vacuum frying negative pressure system, and improve the applicability of the equipment.

[0045] By sliding the rectangular plate 3 on the T-shaped frame 1 and sliding the connecting block 412 on the driving block 411 , adaptive adjustment can be performed before welding the transverse tank body to reserve the required space.

[0046] like Figure 5 , Figure 7 and Figure 8 As shown, the clamping group 51 includes a rectangular bar 510, and the opposite surfaces of the two lifting plates 50 are fixedly provided with the rectangular bar 510, the two rectangular bars 510 are staggered front and back, and the lower end surface of the rectangular bar 510 is fixedly provided with a clamping block 511, the inner arc surfaces of the two clamping blocks 511 are opposite to each other left and right, and the two clamping blocks 511 are symmetrical left and right, and the clamping block 511 corresponding to the left lifting plate 50 is located on the right side of the clamping block 511 corresponding to the right lifting plate 50, and the lower end surface of the lifting plate 50 is fixedly provided with a guide column 512 whose diameter is smaller than the inner diameter of the mounting hole on the ventilation pipe flange.

[0047] like Figure 7 and Figure 8 As shown, the opposite surfaces of the two lifting plates 50 are provided with rectangular grooves 513, the front end surface of the rear rectangular strip 510 and the inner wall of the right rectangular groove 513 are provided with connecting grooves 514, and the rear end surface of the front rectangular strip 510 is fixedly provided with a connecting strip 515.

[0048] During operation, as the two rectangular blocks 31 approach each other, the rectangular blocks 31 drive the lifting plates 50 to move synchronously through the corresponding vertical columns, and the two lifting plates 50 drive the corresponding clamping blocks 511 to move through the rectangular bars 510. At the same time, the two guide columns 512 approach each other and the distance between them is smaller than the farthest distance between the two opposite mounting holes on the vent pipe flange. The vent pipe to be welded is manually placed under the two lifting plates 50 and then the vent pipe is moved upward, so that the two guide columns 512 pass through the mounting holes at the corresponding positions on the vent pipe flange. At the same time, the two clamping blocks 511 are located in the vent pipe, guiding the initial placement process of the vent pipe.

[0049] As the two lifting plates 50 continue to approach, the corresponding two clamping blocks 511 move away from each other, and the two clamping blocks 511 cooperate with each other to open the flange of the ventilation pipe, so that the axis of the ventilation pipe is located between the two lifting plates 50 and the axis is collinear with the axis of the tank body. Secondly, during the above-mentioned movement process, the connecting strip 515 on the rectangular strip 510 is inserted into the rectangular groove 513, so the two lifting plates 50 are integrated in the up and down directions, and the rectangular strip 510 is pressed against the inner wall of the rectangular groove 513 on the relative lifting plate 50 to complete the clamping of the ventilation pipe flange by the clamping block 511, and at the same time, the position of the clamping block 511 is limited to prevent the clamping block 511 from excessively opening the ventilation pipe flange and causing deformation of the ventilation pipe flange.

[0050] Afterwards, the external hydraulic cylinder works to move the lifting plate 50 downward, and the two lifting plates 50 drive the ventilation pipe to move downward synchronously, and finally press the ventilation pipe onto the upper end surface of the tank body and make the lower end of the ventilation pipe close to the tank body, which is convenient for subsequent welding.

[0051] like Figure 5 and Figure 7 As shown, a movable plate 61 located at the lower side of the lifting plate 50 is slidably sleeved on the vertical rod 5, and a spring 2 610 sleeved on the vertical rod 5 is fixedly arranged between the movable plate 61 and the lifting plate 50. The two track plates 60 in the same plate group are fixedly arranged on the end surface of the movable plate 61 away from the vertical rod 5 and the lower end surface of the lifting plate 50 in sequence. The opposite surfaces of the two track plates 60 opposite to each other are provided with a semicircular track groove 611, and a sliding block 1 612 is slidably arranged in the track groove 611 on the two upper lifting plates 50. The Z-shaped frame 52 is fixedly arranged on the sliding block 1 612. The opposite back surfaces of the two track plates 60 opposite to each other on the left side are fixedly provided with two front-to-back symmetrical fixed blocks, and the right end surface of the fixed block is fixedly provided with a horizontal column 614 with an axis extending from left to right. The two track plates 60 on the right side are fixedly provided with mounting blocks 615 corresponding to the corresponding horizontal columns 614, and the mounting blocks 615 are provided with plug holes.

[0052] like Figure 5 , Figure 7 and Fig. 9 As shown, the guide unit 6 also includes a second sliding block 617, and the second sliding block 617 is slidably arranged in the track groove 611 on the two track plates 60 on the lower side. The upper end surface of the second sliding block 617 is provided with a plug-in groove 618, and the lower end surface of the sliding block 1 612 is fixedly provided with a plug-in component 619 through a spring telescopic rod with a vertical axis, and the lower end portion of the plug-in component 619 is divided into a columnar structure that cooperates with the plug-in groove 618.

[0053] like Figure 1 , Figure 5 and Figure 7 As shown, the clamping mechanism 4 also includes an L-shaped frame 7, and the lower end surface of the track plate 60 on the lower side is fixedly provided with the L-shaped frame 7, and the lower end surface of the L-shaped frame 7 is hingedly provided with a triangular block 70, the two triangular blocks 70 are symmetrical on the left and right, and the top angles of the two are opposite to each other on the left and right, and the three circumferential surfaces of the triangular block 70 are hingedly provided with a hinge bar 71, and the tail section of the hinge bar 71 is hingedly provided with a downward pressure block 72, and an annular plate 73 is fixedly provided on the triangular block 70, and a spring three 74 is commonly provided between the annular plate 73 and the corresponding hinge bar 71.

[0054] During operation, as the two lifting plates 50 approach each other, the two moving plates 61 approach each other, and the two left and right opposite track plates 60 approach each other. The horizontal column 614 on the left track plate 60 is inserted into the plug-in hole of the corresponding mounting block 615 of the right corresponding track plate 60 to complete the splicing of the left and right track plates 60. The two left and right opposite track plates 60 together form a circular track with the ventilation pipe and the tank axis as the axis.

[0055] In the process of the lifting plate 50 moving downward, the lifting plate 50 drives the moving plate 61 to move downward synchronously through the spring 2 610, and the moving plate 61 drives the triangular block 70 and the pressing block 72 thereon to move downward synchronously. When the three pressing blocks 72 on the same triangular block 70 move downward and all contact the upper arc surface of the tank body, as the lifting plate 50 continues to move downward, the spring 2 610 is compressed, and the elastic force generated by the compression of the spring 2 610 causes the moving plate 61 to move downward continuously, so that the triangular block 70 and the annular plate 73 continue to move downward, so that the spring 3 74 is compressed, and the elastic force generated by the compression of the spring 3 74 causes the pressing block 72 to press the upper end surface of the tank body, and through all the pressing blocks 72, the lifting plate 50 moves downward continuously. The blocks 72 cooperate with each other to press down the surrounding area of ​​the tank body where the ventilation pipe needs to be welded, so as to cooperate with the clamping action of the clamping plate 40 to improve the stability of the upper end of the tank body during the welding process. Secondly, the three pressing blocks 72 on the same triangular block 70 can provide support for the corresponding movable plate 61 and the track plate 60, thereby improving the stability of the whole circle movement of the welded parts during the subsequent welding process. In addition, the pressing method of the three pressing blocks 72 on the triangular block 70 is convenient to adapt to spherical welding, arc surface welding and plane welding, so that the equipment can adapt to the welding requirements of vertical tank bodies, the welding requirements of horizontal tank bodies and the plane welding requirements of part of the tank body, thereby improving the applicability of the equipment.

[0056] As the lifting plate 50 continues to move downward, the sliding block 1 612 drives the spring telescopic rod and the connector 619 thereon to move downward synchronously, and the columnar structure of the connector 619 is inserted into the plug-in groove 618, so the sliding block 1 612, the sliding block 2 617 and the Z-shaped frame 52 become one, so that when the sliding block 1 612 moves along the track groove 611 of the two upper track plates 60, the lower sliding block 2 617 also moves along the track groove 611 of the corresponding track plate 60, thereby improving the stability of the Z-shaped frame 52 during the whole circle movement process.

[0057] like Figure 2 , Figure 5 and Figure 6 As shown, the clamping mechanism 4 also includes a locking group 8, and a T-shaped rod 80 is rotatably provided on the upper end surface of the rectangular block 31, and the vertical section of the T-shaped rod 80 passes through the corresponding lifting plate 50 and the movable plate 61, and two left-right symmetrical locking grooves 81 are provided on the lifting plate 50 and the movable plate 61, and a plurality of block groups are fixedly provided on the vertical section of the T-shaped rod 80 in sequence from top to bottom, and the block group includes four locking blocks 82 arranged in a matrix.

[0058] During operation, as the lifting plate 50 continues to move downward, the lower pressing block 72 presses the upper end surface of the tank body and the lifting plate 50 presses the ventilation pipe onto the tank body, the horizontal section of the T-shaped rod 80 is manually rotated so that the locking block 82 on the T-shaped rod 80 rotates synchronously and is staggered with the locking groove 81, thereby locking the positions of the lifting plate 50 and the movable plate 61. At this time, the lifting plate 50, the movable plate 61, the vertical rod 5, the track plate 60 and the rectangular block 31 together form a plurality of fixed rectangular frames, which improve the clamping stability of the tank body and the stability during welding.

[0059] Secondly, the multiple block groups can correspond to the clamping requirements before the welding process of different tank bodies. Therefore, when welding different tank bodies, after the lifting plate 50 and the movable plate 61 are moved to the position of the specified block group, the two can be locked by rotating the T-shaped rod 80, which improves the practicality of the device.
