Description

Technical Field

[0001] The present invention relates to an automatic resistance welding device for beer filtration sieve tubes, belonging to the technical field of welding of beer filtration sieve tubes. Background Art

[0002] A sieve tube is a filtering device commonly found in industries such as chemical engineering, pharmaceuticals, and food. It is usually used for screening, filtering, or separating solid particles or liquid substances, playing a role in filtering impurities, improving work efficiency and product quality. Sieve tubes are usually divided into vibrating sieve tubes and pressure sieve tubes, and the specific usage scenarios are slightly different.

[0003] The filtering effect of beer has a direct impact on the taste and texture of beer. In the beer production process, filtration is generally carried out through sieve tubes. When using sieve tubes for filtration, as Figure 1 shown, one end of the sieve tube 6 needs to be welded to the top seat 5. The sieve tube 6 is installed and fixed in the filtering device through the top seat 5. In the prior art, when welding the sieve tube 6 and the top seat 5, generally, the sieve tube 6 and the top seat 5 are first fixed on corresponding jigs manually, and then the two jigs are butted manually to achieve the welding of the sieve tube 6 and the top seat 5. During the entire welding process, the sieve tube 6 and the top seat 5 are loaded and unloaded manually, and manual operation is required for welding. The degree of automation is low, and a large amount of labor is occupied.

[0004] In addition, due to the small diameter and large length of the sieve tube, the loading and unloading mechanisms for tubular materials in the prior art cannot meet the loading and unloading of sieve tubes. First, to meet the dimensional requirements of the sieve tube, the bin for holding the sieve tube is large, and it is inconvenient to store and load sieve tubes of different length dimensions; second, the diameter of the sieve tube is small, and it is not easy to achieve single - order feeding of sieve tubes during automatic feeding.

[0005] In summary, it is obvious that the prior art has inconveniences and defects in actual use, so it is necessary to improve. Summary of the Invention

[0006] In view of the deficiencies in the background art, the present invention provides an automatic resistance welding device for beer filtration sieve tubes, which can automatically complete the loading and unloading of sieve tubes through a sieve tube loading and unloading mechanism. The top seat loading mechanism can efficiently load the top seats, and can automatically dock and weld the sieve tubes and the top seats. The overall structure is simple, and finally the entire welding process is made more efficient, replacing manual operations.

[0007] To solve the above technical problems, the present invention adopts the following technical solutions: An automatic resistance welding device for beer filtration sieve tubes includes a sieve tube loading and unloading mechanism, a top seat loading mechanism, and a resistance welding mechanism;

[0008] The sieve tube loading and unloading mechanism includes a sieve tube loading mechanism for realizing the loading of sieve tubes and a loading and unloading base. The sieve tube loading mechanism is installed on one side of the top of the loading and unloading base. On the other side of the top of the loading and unloading base, two second lifting cylinders are arranged side by side. A V-shaped bearing block is installed at the telescopic end of the second lifting cylinder;

[0009] A first linear module is also installed on the loading and unloading base. The sliding part of the first linear module is connected with a cylinder mounting frame. A first finger cylinder is installed on the cylinder mounting frame. A clamping jaw is installed on each of the two fingers of the first finger cylinder. The first finger cylinder is arranged collinearly with the two V-shaped bearing blocks;

[0010] The top seat loading mechanism includes a top seat storage bin and a second finger cylinder driven by a second linear module. A clamping block is installed on each of the two fingers of the second finger cylinder.

[0011] Further, the resistance welding mechanism includes a clamping and positioning mechanism and a sliding clamping mechanism. The clamping jaws of the first finger cylinder clamp the sieve tube and push it into the clamping and positioning mechanism. The clamping blocks of the second finger cylinder clamp the top seat and push it into the sliding clamping mechanism.

[0012] Further, the clamping and positioning mechanism is connected to the zero wire terminal of the electric control box through a zero wire connection board. The sliding clamping mechanism is connected to the live wire terminal of the electric control box through a live wire connection board.

[0013] Further, a welding base is provided at the lower ends of the clamping and positioning mechanism and the sliding clamping mechanism. The lower end of the sliding clamping mechanism is slidably installed on one side of the welding base through a third slide rail. A servo module is also fixed on the welding base. The servo module drives the sliding clamping mechanism to slide; The clamping and positioning mechanism is fixed on the other side of the welding base.

[0014] Further, the sieve tube loading mechanism includes two oppositely arranged discharging devices. The discharging device includes a cover plate and a bottom plate which are arranged parallel to each other at intervals up and down. The gap between the two forms a discharging channel. The cover plate and the bottom plate are inclined;

[0015] The discharging device also includes a sieve tube storage bin arranged at the rear ends of the cover plate and the bottom plate. The sieve tube storage bin includes two baffles arranged parallel to each other at intervals. The upper end of the discharging channel is communicated with the sieve tube storage bin.

[0016] Further, a blocking block is installed at the outlet at the front end of the bottom plate. A guide plate is inclinedly installed on one side of the blocking block close to the V-shaped bearing block. Two first lifting cylinders are arranged side by side at the position of the front end outlet of the discharging channel between the two discharging devices. A first top block is installed at the telescopic end of the first lifting cylinder. The upper surface of the first top block is inclined towards the side of the V-shaped bearing block.

[0017] Further, the bottom of the first linear module is slidably mounted on the loading and unloading base through a first slide rail, and the position of the first linear module is adjustable in the axial direction of the screen pipe; the discharging device near the first finger cylinder is slidably arranged through a second slide rail, and the distance between the two discharging devices is adjustable.

[0018] Further, the screen pipe loading and unloading mechanism further includes a screen pipe unloading mechanism, and the screen pipe unloading mechanism includes two return baffle plates arranged side by side. Each return baffle plate includes a top inclined plate arranged at the upper end and a bottom inclined plate arranged at the lower end. Both the top inclined plate and the bottom inclined plate are inclined towards one side. The top inclined plate is located on one side of the V-shaped bearing block, and the height of the top inclined plate is between the highest position and the lowest position of the V-shaped bearing block.

[0019] Further, the top seat bin includes a plurality of vertically arranged top seat slots. The cross-sectional size of the top seat slot is adapted to the size of the top seat. The top seats are vertically arranged in the top seat slots. A top seat discharge port penetrating through the front and rear is provided at the lower end of the top seat slot, and a pushing cylinder is correspondingly installed at the rear end of the top seat discharge port. A pushing block is installed at the telescopic end of the pushing cylinder.

[0020] Further, two vibrating cylinders are arranged side by side between the two screen pipe bins, and a second top block is installed at the telescopic end of the vibrating cylinder.

[0021] After the present invention adopts the above technical solutions, compared with the prior art, it has the following advantages:

[0022] 1. The screen pipe loading mechanism includes two relatively inclined discharging channels. The upper end of the discharging channel is communicated with the screen pipe bin. The first lifting cylinder pushes the first top block to rise, jacks up the screen pipe at the front end of the discharging channel, and the screen pipe slides along the guide plate into the V-shaped bearing block, completing the loading of the screen pipe from the screen pipe loading mechanism; the screen pipe bin automatically discharges smoothly through the inclined discharging channel without a power device, and is sent to the V-shaped bearing block under the push of the first lifting cylinder, replacing manual operation.

[0023] 2. The screen pipe unloading mechanism includes two return baffle plates arranged side by side. When the screen pipe is welded to the top seat to complete unloading, the first finger cylinder pulls the screen pipe out of the clamping and positioning mechanism through the claw, so that the screen pipe is in the loading position; at this time, the V-shaped bearing block falls back to the lowest position under the push of the second lifting cylinder. At this time, the screen pipe falls onto the top inclined plate, and the screen pipe rolls from the top inclined plate to the bottom inclined plate to realize unloading; the first finger cylinder acts reversely and pulls the screen pipe back, making the V-shaped bearing block a transfer position for loading and unloading. The V-shaped bearing block can be used for both loading and unloading at the same time, and the screen pipe is cleverly recovered with the help of the blocking of the return baffle plate. The structure is simple and automatic unloading is realized.

[0024] 3. The top seats in the top seat chute are arranged vertically, making the structure of the top seat bin simpler and smaller in volume. During discharging, it automatically falls and discharges under the action of gravity. The pushing cylinder is close to the back side of the discharging port of the top seat, with a short action stroke and a fast feeding speed.

[0025] 4. The resistance welding mechanism includes a clamping and positioning mechanism and a sliding clamping mechanism. The electric clamping heads of the clamping and positioning mechanism and the sliding clamping mechanism respectively clamp the sieve tube and the top seat. The servo module drives the sliding clamping mechanism to approach the clamping and positioning mechanism, making the welding end of the sieve tube fit with the top seat and fusing the two to complete the welding. During the whole welding process, no manual participation is required, and the welding time is completely controlled electrically, with a high degree of automation and good welding quality.

Detailed implementation mode

[0037] For a clearer understanding of the technical features, objectives, and effects of the present invention, the specific implementation mode of the present invention will now be described with reference to the accompanying drawings.

[0038] As Figure 2-3 shown, the present invention provides an automatic resistance welding device for beer filtration sieve tubes, including a sieve tube loading and unloading mechanism 1, a top seat loading mechanism 2, and a resistance welding mechanism 3.

[0039] As Figure 4 shown, the sieve tube loading and unloading mechanism 1 includes a sieve tube loading mechanism for realizing the loading of the sieve tube 6 and a loading and unloading base 101. The sieve tube loading mechanism is installed on one side of the top of the loading and unloading base 101. On the other side of the top of the loading and unloading base 101, two second lifting cylinders 108 are arranged side by side. The telescopic end of the second lifting cylinder 108 is installed with a V-shaped bearing block 109. The sieve tube loading mechanism sends the sieve tube 6 to the two side-by-side arranged V-shaped bearing blocks 109.

[0040] A first linear module 112 is also installed on the loading and unloading base 101. The sliding part of the first linear module 112 is connected with a cylinder mounting bracket 113. A first finger cylinder 111 is installed on the cylinder mounting bracket 113. One claw 110 is installed on each of the two fingers of the first finger cylinder 111; the first finger cylinder 111 is arranged collinearly with the two V-shaped bearing blocks 109. The first linear module 112 drives the first finger cylinder 111 to move back and forth along the axis direction of the sieve tube 6. The claw 110 of the first finger cylinder 111 clamps one end of the sieve tube 6 and moves along the axial direction of the tube, pushing the sieve tube 6 into the resistance welding mechanism 3 for welding.

[0041] The top seat feeding mechanism 2 includes a top seat magazine and a second finger cylinder 205 driven by a second linear module 203. A clamping block 206 is installed on each of the two fingers of the second finger cylinder 205. The clamping block 206 clamps the top seat 5 discharged from the top seat magazine, and under the drive of the second linear module 203, the clamping block 206 pushes the top seat 5 into the resistance welding mechanism 3 for welding.

[0042] As Figure 8 , the resistance welding mechanism 3 includes a clamping and positioning mechanism 301 and a sliding clamping mechanism 302. The jaws 110 of the first finger cylinder 111 clamp the sieve tube 6 and push it into the clamping and positioning mechanism 301, and the clamping block 206 of the second finger cylinder 205 clamps the top seat 5 and pushes it into the sliding clamping mechanism 302; the clamping and positioning mechanism 301 is connected to the zero - wire terminal of the electric control box 4 through a zero - wire connection board 306, and the sliding clamping mechanism 302 is connected to the live - wire terminal of the electric control box 4 through a live - wire connection board 307.

[0043] As Figure 8 , a welding base 304 is provided at the lower ends of the clamping and positioning mechanism 301 and the sliding clamping mechanism 302. The lower end of the sliding clamping mechanism 302 is slidably installed on one side of the welding base 304 through a third slide rail 305, and a servo module 303 is also fixed on the welding base 304. The servo module 303 drives the sliding clamping mechanism 302 to slide; the clamping and positioning mechanism 301 is fixed on the other side of the welding base 304. Electric clamping heads are installed on the opposite sides of the clamping and positioning mechanism 301 and the sliding clamping mechanism 302. The electric clamping heads of the clamping and positioning mechanism 301 and the sliding clamping mechanism 302 respectively clamp the welding end of the sieve tube 6 and the top seat 5, so that the sieve tube 6 and the top seat 5 are coaxially arranged opposite to each other. The servo module 303 drives the sliding clamping mechanism 302 to approach the clamping and positioning mechanism 301, so that the welding end of the sieve tube 6 and the top seat 5 are in contact. Since the sieve tube 6 is connected to the zero - wire and the top seat 5 is connected to the live - wire, a large current is generated when the two are in contact, causing them to fuse and complete the welding. During the whole welding process, no manual participation is required, and the welding time is completely controlled electrically, with high automation and good welding quality.

[0044] As Figure 4, the sieve tube feeding mechanism includes two oppositely arranged discharging devices. Each discharging device includes a cover plate 102 and a bottom plate 103 which are arranged parallel to each other at an upper and lower interval. The gap between them forms a discharging channel. The cover plate 102 and the bottom plate 103 are inclined so that the sieve tubes 6 discharged from the front end outlet of the discharging channel slide onto two V-shaped bearing blocks 109. The discharging device also includes a sieve tube bin arranged at the rear ends of the cover plate 102 and the bottom plate 103. The sieve tube bin includes two baffles 104 arranged parallel to each other at an interval. The upper end of the discharging channel is communicated with the sieve tube bin. The two ends of the sieve tube 6 are respectively placed in the sieve tube bins of the two discharging devices. Due to the inclined arrangement of the discharging channel, under the action of gravity, as the feeding progresses, the sieve tubes 6 are continuously discharged from the discharging channel.

[0045] As Figure 4 , at the outlet at the front end of the bottom plate 103, a blocking block 106 is installed. On the side of the blocking block 106 close to the V-shaped bearing block 109, a guiding plate 117 is installed obliquely. Between the two discharging devices, at the position of the front end outlet of the discharging channel, two first lifting cylinders 107 are arranged side by side. The telescopic end of the first lifting cylinder 107 is installed with a first top block, and the upper surface of the first top block is inclined towards the side of the V-shaped bearing block 109. The sieve tube 6 at the front end of the discharging channel is blocked by the blocking block 106. During feeding, the first lifting cylinder 107 pushes the first top block to rise, lifting the sieve tube 6 at the front end of the discharging channel. The sieve tube 6 slides along the guiding plate 117 into the V-shaped bearing block 109, completing the feeding of the sieve tube 6 from the sieve tube feeding mechanism. The sieve tube bin automatically discharges materials smoothly through the inclined discharging channel without a power device, with a simple structure. It is sent to the V-shaped bearing block 109 under the push of the first lifting cylinder 107, replacing manual operation.

[0046] As Figure 4 , the bottom of the first linear module 112 is slidably installed on the loading and unloading base 101 through a first slide rail 114. The first linear module 112 is adjustable in position along the axial direction of the sieve tube 6. After adjusting the position of the first linear module 112, it is locked by a locking device. The discharging device close to the first finger cylinder 111 is slidably arranged through a second slide rail 118, so that the distance between the two discharging devices is adjustable. After adjusting the position of the discharging device, it is locked by a locking device. The lengths of the sieve tubes 6 are different. When the sieve tube 6 is longer, the adjustable discharging device is moved towards the outer end, so that the distance between the two discharging devices is adapted to the length of the sieve tube 6. At the same time, the first linear module 112 is moved towards the outer end, so that the clamping jaws 110 can clamp the end of the sieve tube 6. When the sieve tube 6 is shorter, the discharging device and the first linear module 112 are adjusted in the reverse direction, so that the sieve tube loading and unloading mechanism 1 can be universal for sieve tubes 6 of different sizes and specifications.

[0047] As Figure 4, two vibration cylinders 105 are arranged side by side between two sieve tube bins. A second top block is installed at the telescopic end of the vibration cylinder 105. The vibration cylinder 105 pushes the second top block to move up and down, thereby being able to drive the sieve tube 6 in the sieve tube bin to move, preventing the sieve tube 6 from getting stuck in the sieve tube bin and causing poor feeding.

[0048] As Figure 4-6 , the sieve tube loading and unloading mechanism 1 further includes a sieve tube unloading mechanism. The sieve tube unloading mechanism includes two return material baffles 116 arranged side by side. The return material baffle 116 includes a top inclined plate 1161 provided at the upper end and a bottom inclined plate 1162 provided at the lower end. Both the top inclined plate 1161 and the bottom inclined plate 1162 are inclined towards one side. The top inclined plate 1161 is located on one side of the V-shaped bearing block 109, and the height of the top inclined plate 1161 is between the highest position and the lowest position of the V-shaped bearing block 109.

[0049] When the sieve tube 6 is loaded, the V-shaped bearing block 109 is at the highest position under the push of the second lifting cylinder 108, so that the sieve tube 6 is placed in the V-shaped bearing block 109; when the sieve tube 6 is welded to the top seat 5 and unloaded, the first finger cylinder 111 pulls the sieve tube 6 out of the clamping and positioning mechanism 301 through the clamp 110, so that the sieve tube 6 is in the loading position; at this time, the V-shaped bearing block 109 falls back to the lowest position under the push of the second lifting cylinder 108. At this time, the sieve tube 6 falls onto the top inclined plate 1161, and the sieve tube 6 rolls from the top inclined plate 1161 to the bottom inclined plate 1162 to achieve unloading. When unloading, the first finger cylinder 111 acts reversely to pull back the sieve tube 6, making the V-shaped bearing block 109 the transfer position for loading and unloading. The V-shaped bearing block 109 can be used for both loading and unloading at the same time. With the blocking of the return material baffle 116, the sieve tube 6 is cleverly retracted. The structure is simple and automatic unloading is achieved.

[0050] A material blocking brush 115 is fixedly installed at the upper end position of the bottom inclined plate 1162. The material blocking brush 115 blocks the downward rolling of the sieve tube 6 and slows down its speed; a blocking plate 119 is installed at the lower end of the bottom inclined plate 1162 to block the sieve tube 6 after unloading.

[0051] As Figure 7, the top seat bin includes a plurality of vertically arranged top seat troughs 201. The cross-sectional dimension of the top seat trough 201 is adapted to the dimension of the top seat 5. The top seats 5 are vertically arranged in the top seat trough 201. A top seat discharge port that penetrates through the front and back is provided at the lower end of the top seat trough 201. A pushing cylinder 202 is correspondingly installed at the rear end of the top seat discharge port, and a pushing block is installed at the telescopic end of the pushing cylinder 202. When it is necessary to discharge the top seat trough 201, the second finger cylinder 205 drives two clamping blocks 206 to move to the position of the top seat discharge port. The corresponding pushing cylinder 202 makes the pushing block move forward, pushing the top seat 5 between the two clamping blocks 206. The second finger cylinder 205 drives the two clamping blocks 206 to clamp the top seat 5, completing the material taking. The top seats 5 in the top seat trough 201 are vertically arranged, making the structure of the top seat bin simpler and smaller in volume. When discharging, it automatically falls and discharges under the action of gravity. The pushing cylinder 202 is closely adjacent to the back side of the top seat discharge port, and the action stroke of the pushing cylinder 202 is short, and the feeding speed is fast.

[0052] The sliding member of the second linear module 203 is connected with a connecting arm 204. The length extension direction of the connecting arm 204 is consistent with the moving direction of the second linear module 203. The second finger cylinder 205 is installed on the connecting arm 204, extending the outward moving distance of the second finger cylinder 205.

[0053] The above is an example of the best implementation mode of the present invention. The parts not described in detail are all common general knowledge of those of ordinary skill in the art. The protection scope of the present invention is subject to the content of the claims. Any equivalent transformation based on the technical inspiration of the present invention is also within the protection scope of the present invention.
