An installation groove 27 is opened on the surface of the swing arm 9, a brush plate mounting plate 35 is hinged inside the installation groove 27, and a brush plate 33 is arranged on the surface of the brush plate mounting plate 35; the feeding and straightening device not only meets the deviation correction during the transportation of the electric heating tube, but also meets the filling of the side plate notch of the feeding conveyor belt 4, and also meets the cleaning of the surface of the feeding conveyor belt 4. In this way, the feeding and straightening device has multiple functions; further solves the problems of large volume and single function of the existing feeding and straightening device; can realize that the feeding and straightening device meets the hidden storage while realizing multiple functions.

[0041] Embodiment 2. Referring to Fig.12 and Fig. 20 shown, on the basis of Embodiment 1, in order to install the feeding and straightening device on the feeding conveyor belt 4, reserved grooves 3 are opened on both side plates of the feeding conveyor belt 4 distributed in parallel. The reserved groove 3 is a square groove, the buckle plate 2 is in a "C"-shaped plate structure, the height of the buckle plate 2 is equal to the height of the reserved groove 3, the bottom surface of the buckle plate 2 and the bottom surface of the substrate 1 are coplanar, and the side plates of the buckle plate 2 and the side plates of the feeding conveyor belt 4 are both penetrated by through holes 5, and the bolts 6 penetrate through the through holes 5 on the buckle plate 2 and the side plates of the feeding conveyor belt 4 and then are locked.

[0042] There is an assemblable structure between the feeding straightening device and the feeding conveyor belt 4, that is, the feeding straightening device is an optional mechanism of the feeding conveyor belt 4. When the feeding straightening device is optionally installed on the feeding conveyor belt 4, it is necessary to open a reserved groove 3 on the side of the side panel of the feeding conveyor belt 4 close to the feed end for embedding the feeding straightening device. The feeding straightening device extends from the reserved groove 3 when in use. When the feeding straightening device is idle, the feeding straightening device is embedded in the reserved groove 3. At this time, the feeding straightening device fills the gap of the reserved groove 3 to act as the side panel of the feeding conveyor belt 4. In this way, the feeding straightening device can serve two purposes, not only meeting the need for correcting the deviation of the electric heating tube during transportation, but also meeting the need for filling the gap in the side panel of the feeding conveyor belt 4.

[0043] When installing the feeding and straightening device, the two buckle plates 2 of the feeding and straightening device are clipped onto the two sides of the reserved groove 3 from top to bottom. When the bottom surfaces of the base plate 1 and the buckle plate 2 are overlapped on the bottom surfaces of the reserved groove 3, the screw rod of the bolt 6 is passed through the through holes 5 on the surface of the buckle plate 2 and the feeding conveyor belt 4, and then the nut is locked on the screw rod. During installation, the nut is installed on the side of the conveyor belt away from the feeding conveyor belt 4 to avoid the screw rod being too long and extending toward the conveyor belt to create a hidden danger of blocking the transmission of the workpiece.

[0044] Embodiment 3, refer to the attached Figure 2 As shown, on the basis of the second embodiment, in order to use the brush plate 33 to clean the conveyor belt surface of the feeding conveyor belt 4, the height of the second mounting groove 27 is less than the height of the swing arm 9, one end of the second mounting groove 27 is connected to the first mounting groove 15, and a limiting shaft 3 28 is fixed on the bottom surface of the second mounting groove 27. The limiting shaft 3 28 has a "T"-shaped column structure, and the limiting shaft 3 28 passes through the through hole 3 29. The through hole 3 29 is provided on the surface of the brush plate mounting plate 35. The top surface diameter of the limiting shaft 3 28 is larger than the aperture of the through hole 3 29. The top surface of the brush plate mounting plate 35 is provided with a positioning groove 30, and the positioning groove 30 is provided with two, and the two positioning grooves 3 0 is distributed at an angle of ninety degrees with the limiting shaft three 28 as the central axis. A positioning screw 31 is screwed on the top surface of the limiting shaft three 28, and the positioning screw 31 penetrates the top plate of the limiting shaft three 28 and is inserted into the positioning groove 30; a mounting groove three 32 is opened on the bottom surface of the brush plate mounting plate 35, and the brush plate 33 is inserted into the mounting groove three 32. A screw 34 is screwed on the surface of the brush plate 33, and the screw 34 penetrates the brush plate 33 and is screwed on the surface of the mounting groove three 32. After the brush plate mounting plate 35 is retracted into the mounting groove two 27, the bristles of the brush plate 33 are squeezed and deformed. After the brush plate mounting plate 35 extends out from the mounting groove two 27, the bristles of the brush plate 33 pop out.

[0045] The brush plate 33 is then moved back and forth to move the brush plate 35 so as to move the brush plate 35 upwards and downwards to move the brush plate 35 downwards, so as to move the brush plate 35 downwards and upwards to move the brush plate 35 downwards. The brush plate 33 is then removed from the feeding conveyor belt 4 and the particles blocked in front of the brush plate 33 are removed from the feeding conveyor belt 4. Then, after loosening the positioning screw 31, the brush plate mounting plate 35 is pushed back to be stored in the mounting groove 27, and the positioning screw 31 is turned back to brake the brush plate mounting plate 35. When the bristles of the brush plate 33 are worn to the point where they can no longer block the particles, the screws 34 are loosened to disengage from the mounting groove 32, and the brush plate 33 is removed and replaced with a new brush plate 33. It should be noted that, according to actual needs, the brush plate mounting plate 35 and the brush plate 33 can be set as a telescopic structure to adapt to feeding conveyor belts 4 of different widths to ensure that the surface cleaning coverage of the feeding conveyor belt 4 is guaranteed. At this time, the feeding straightening device not only meets the needs of correcting the deviation of the electric heating pipe during transportation, but also meets the needs of filling the gap in the side plate of the feeding conveyor belt 4, and also meets the needs of cleaning the surface of the feeding conveyor belt 4. In this way, the feeding straightening device can be used for multiple purposes.

[0046] Embodiment 4, refer to the attached Figure 5 , Figure 6 , Figures 9 to 19 As shown, on the basis of the third embodiment, in order to realize the swing arm 9 cooperating with the straightening guide plate 36 to correct the deviation of the electric heating tube transmitted on the feeding conveyor belt 4, a limit shaft 7 is fixed on the top surface of the substrate 1, and the limit shaft 7 is a "T"-shaped cylinder. The rod body of the limit shaft 7 passes through a through hole 8, and the through hole 8 is opened on the surface of the swing arm 9. The top surface diameter of the limit shaft 7 is larger than the aperture of the through hole 8. One end of the swing arm 9 is an arc-shaped surface, and a plurality of positioning slots 10 are opened on the arc-shaped surface. The connecting piece 11 is in the swing Above one end of the arm 9, the connecting piece 11 is in the shape of a "U" plate structure, and the positioning plug 12 passes through the inner ring of the connecting piece 11 and is inserted into the positioning slot 10; the positioning plug 12 is in the shape of a "concave" block, and an elastic band 13 is fixed to the bottom surface of the groove body of the positioning plug 12, and both ends of the elastic band 13 are fixed to the top surface of the connecting piece 11, and the two ends of the elastic band 13 are respectively distributed on both sides of the inner ring of the connecting piece 11, and a pull rod 14 is fixed between the two parallel side walls of the groove body at the top of the positioning plug 12.

[0047] First, it is necessary to pull the swing arm 9 out from between the two buckle plates 2 and then brake. The specific operation is as follows: pinch the pull rod 14 to pull out the positioning block 12, and the positioning block 12 pulls the elastic band 13 to produce elastic deformation. When the bottom end of the positioning block 12 is pulled out from the positioning slot 10, the other hand moves the swing arm 9 to rotate to the inner side of the feeding conveyor belt 4 with the limit axis 7 as the central axis to the required angle. Since the angles between the multiple positioning slots 10 are equal, the position of the swing arm 9 is adjusted to meet the corresponding positioning slot 10 below the positioning block 12. At this time, after releasing the pull rod 14, the elastic band 13 rebounds and pulls the positioning block 12 downward, and the positioning block 12 is inserted into the corresponding connecting piece 11, thereby braking the swing arm 9; it is necessary to adjust the two sets of swing arms 9 to the inner side of the feeding conveyor belt 4, and the two sets of adjusted swing arms 9 are distributed in an inverted "eight" shape.

[0048] In order to adjust the inclination angle of the straightening guide plate 36, the mounting groove 15 is an "L"-shaped groove, the height of the mounting groove 15 is less than the height of the swing arm 9, the end of the mounting groove 15 away from the connecting piece 11 is fixed with a limiting shaft 2 16, the limiting shaft 2 16 is a cylindrical structure, the limiting shaft 2 16 passes through the through hole 2 17, the through hole 2 17 is provided at one end of the straightening guide plate 36, the straightening guide plate 36 is an "L"-shaped plate structure, the end of the straightening guide plate 36 close to the limiting shaft 2 16 is a cylindrical structure, the height of the limiting shaft 2 16 is equal to the height of the straightening guide plate 36, and the brake assembly The brake assembly includes a baffle 20 and a clamping screw 21 screwed to the top surface of the baffle 20. The top surface of the straightening guide plate 36 is provided with an embedding groove 18, which is an annular groove. A rubber pad 19 is fixed inside the embedding groove 18. The thickness of the rubber pad 19 is greater than the depth of the embedding groove 18. The rubber pad 19 is clamped between the baffle 20 and the straightening guide plate 36 to produce elastic deformation. The rubber pad 19 is an annular plate structure, and the baffle 20 is a "middle" shaped plate structure. The clamping screw 21 penetrates the baffle 20 and clamps the rubber pad 19.

[0049] After the two swing arms 9 are adjusted, the area between the ends of the two swing arms 9 is the center axis area of ​​the electric heating pipe when it is transported on the feeding conveyor belt 4. In order to guide the transported electric heating pipe to between the two swing arms 9, it is necessary to pull out the straightening guide plate 36 from the installation groove 15. After the two straightening guide plates 36 are pulled out and braked, the two straightening guide plates 36 are distributed in an "eight" shape to guide the electric heating pipe pushed in at the end of the feeding conveyor belt 4. The specific adjustment operation is as follows: loosen the clamping screw 21 to no longer clamp the rubber pad 19, and after the straightening guide plate 36 is rotated to the required angle with the limit shaft 2 16 as the center axis, the clamping screw 21 is retracted to clamp the rubber pad 19 to achieve braking of the straightening guide plate 36. At this time, the state diagram is attached. Figure 4 shown.

[0050] In order to prevent small workpieces from passing through the gap between the bottom surface of the straightening guide plate 36 and the conveyor belt of the loading conveyor belt 4, a side groove 22 is opened on the bottom surface of the straightening guide plate 36, and the side groove 22 is an inverted "convex" shaped groove. An extension baffle 23 is inserted into the inside of the side groove 22, and the extension baffle 23 is a "T" shaped plate structure. The thickness of the extension baffle 23 is less than the depth of the side groove 22. A baffle bar 24 is fixed between two parallel side walls of the side groove 22, and the baffle bar 24 is a "concave" shaped bar. A traction bar 25 is fixed on the surface of the extension baffle 23, and an elastic band 26 is fixed between the bottom surface of the traction bar 25 and the bottom surface of the groove body of the baffle bar 24. When the straightening guide plate 36 is pushed into the installation groove 15, the extension baffle 23 retracts into the side groove 22. At this time, the elastic band 26 is stretched by the traction bar 25 to produce elastic deformation.

[0051] After popping up, the extended baffle 23 rests on the top of the feeding conveyor belt 4. When the straightening guide plate 36 needs to be pushed into the installation groove 15 for storage, the extended baffle 23 needs to be pushed into the side groove 22 to prevent the extended baffle 23 from blocking the straightening guide plate 36 from entering the installation groove 15, that is, the traction bar 25 is pushed up to lift the side groove 22 by fingers. During this process, the traction bar 25 tensions the elastic band 26 to produce elastic deformation.

[0052] Embodiment 5, based on embodiment 4, proposes a method for using a feeding device for processing electric heating tubes, comprising the following steps:

[0053] Step 1: When installing the feeding and straightening device, the two buckle plates 2 of the feeding and straightening device are clipped on both sides of the reserved groove 3 from top to bottom. When the bottom surfaces of the base plate 1 and the buckle plate 2 are overlapped on the bottom surfaces of the reserved groove 3, the screw rod of the bolt 6 passes through the through holes 5 on the surface of the buckle plate 2 and the feeding conveyor belt 4, and then the nut is locked on the screw rod. When installing, the nut is installed on the side of the conveyor belt away from the feeding conveyor belt 4 to avoid the hidden danger of the screw rod being too long and extending toward the conveyor belt to block the transmission of the workpiece; the feeding and straightening device and the feeding conveyor belt 4 are an assembleable structure, that is, the feeding and straightening device is an upper The optional mechanism of the feeding conveyor belt 4, when the feeding conveyor belt 4 is equipped with a feeding straightening device, a reserved groove 3 needs to be opened on the side of the side plate of the feeding conveyor belt 4 close to the feeding end for embedding the feeding straightening device. The feeding straightening device extends from the reserved groove 3 when in use. When the feeding straightening device is idle, the feeding straightening device is embedded in the reserved groove 3. At this time, the feeding straightening device fills the gap of the reserved groove 3 and acts as the side plate of the feeding conveyor belt 4. In this way, the feeding straightening device can be used for two purposes, not only to correct the deviation of the electric heating pipe during transportation, but also to fill the gap of the side plate of the feeding conveyor belt 4;

[0054] Step 2: Before and after the start of the electric heating tube transmission work, in order to sweep away the debris adhered to the surface of the feeding conveyor belt 4, it is necessary to place the brush plate 33 flat on the top of the feeding conveyor belt 4, and use the brush plate 33 to clean the surface of the running feeding conveyor belt 4. The specific operation is as follows: loosen the positioning screw 31. After the top of the positioning screw 31 is pulled out of the positioning groove 30, move the brush plate mounting plate 35 to rotate ninety degrees to the outside of the mounting groove 27 with the limiting axis three 28 as the central axis. At this time, the brush plate mounting plate 35 and the swing arm 9 are perpendicular. The positioning screw 31 is screwed back and inserted into the corresponding positioning groove 30 to brake the brush plate mounting plate 35. At this time, the bristles of the brush plate 33 are against the conveyor belt of the feeding conveyor belt 4, triggering the switch of the feeding conveyor belt 4. During the operation of the feeding conveyor belt 4, the brush plate 3 3 blocks the particles on the surface of the feeding conveyor belt 4. After the feeding conveyor belt 4 rotates for several cycles, the feeding conveyor belt 4 is stopped, and the particles blocked in front of the brush plate 33 are removed from the feeding conveyor belt 4. Then, after loosening the positioning screw 31, the brush plate mounting plate 35 is pushed back to the second mounting groove 27 for storage, and the positioning screw 31 is re-screwed to brake the brush plate mounting plate 35. When the bristles of the brush plate 33 are worn to the point where they cannot block the particles, the loose screw 34 is disengaged from the third mounting groove 32, and the brush plate 33 is removed and replaced with a new brush plate 33. It should be noted that the brush plate mounting plate 35 and the brush plate 33 can be set as a telescopic structure according to actual needs to adapt to feeding conveyor belts 4 of different widths to ensure that the surface cleaning coverage of the feeding conveyor belt 4 is guaranteed.

[0055] Step three: first pull out the swing arm 9 from between the two gusset plates 2 and then brake. The specific operation is as follows: pinch the pull rod 14 by hand to pull out the positioning plug block 12, and the positioning plug block 12 pulls the elastic band 13 to produce elastic deformation. When the bottom end of the positioning plug block 12 is pulled out from the positioning slot 10, the other hand moves the swing arm 9 with the limit axis 7 as the central axis to the inner side of the upper feeding conveyor belt 4 to the required angle. Since the angles between the multiple positioning slots 10 are equal, the position of the swing arm 9 is adjusted to meet the corresponding positioning slot 10 below the positioning plug block 12. At this time, after releasing the pull rod 14, the elastic band 13 rebounds and pulls the positioning plug block 12 downward, and the positioning plug block 12 is inserted into the corresponding connecting piece 11, thereby realizing the braking of the swing arm 9; it is necessary to adjust both sets of swing arms 9 to the inner side of the feeding conveyor belt 4, and the two sets of adjusted swing arms 9 are distributed in an inverted "eight" shape;

[0056] Step 4: After the two swing arms 9 are adjusted, the area between the ends of the two swing arms 9 is the center axis area of ​​the electric heating pipe when it is transported on the feeding conveyor belt 4. In order to guide the transported electric heating pipe to between the two swing arms 9, it is necessary to pull out the straightening guide plate 36 from the installation groove 15. After the two straightening guide plates 36 are pulled out and braked, the two straightening guide plates 36 are distributed in an "eight" shape to guide the electric heating pipe pushed in at the end of the feeding conveyor belt 4. The specific adjustment operation is as follows: loosen the clamping screw 21 to no longer clamp the rubber pad 19, and after the straightening guide plate 36 is rotated to the required angle with the limit shaft 2 16 as the center axis, re-tighten the clamping screw 21 to clamp the rubber pad 19 to achieve braking of the straightening guide plate 36. At this time, the state diagram is attached. Figure 4 As shown;

[0057] Step 5: After popping up, the extended baffle 23 rests on the top of the feeding conveyor belt 4. When the straightening guide plate 36 needs to be pushed into the installation groove 15 for storage, the extended baffle 23 needs to be pushed into the side groove 22 to prevent the extended baffle 23 from blocking the straightening guide plate 36 from entering the installation groove 15. That is, the traction bar 25 is pushed up to lift the side groove 22 by fingers. During this process, the traction bar 25 tensions the elastic band 26 to produce elastic deformation.
