The square sleeve feeding device realizes the feeding action of the square sleeve 91 by adopting the following manner, as shown in fig. 15, 16 and 17, the square sleeve feeding mechanism comprises a square sleeve charging barrel 71, a square sleeve rail 72 which spirally ascends along the inner circumferential surface of the square sleeve charging barrel 71, and a square sleeve vibration disc 73 which is arranged in the Fang Taoliao barrel 71, wherein the top end of the square sleeve rail 72 is connected with a vertical plate channel 74, and the thickness of the vertical plate channel 74 is not more than the width of a vertical slot 913; as shown in fig. 15 and 18, the material distributing mechanism comprises a vertical channel 81 with the top end communicated with the vertical plate channel 74 and a horizontal channel 82 communicated with the bottom end of the vertical channel 81, a seventh air cylinder 83 is fixed at one end of the horizontal channel 82 through bolts, a pushing square column 88 is integrally formed at the piston rod end of the seventh air cylinder 83, and the pushing square column 88 is in plug-in fit along the length direction of the horizontal channel 82; the eighth cylinder 84 is fixedly installed at the other end of the horizontal channel 82, and a piston rod of the eighth cylinder 84 is perpendicular to the horizontal channel 82 and is in penetrating fit with the horizontal channel 82.

15-18, the square sleeve vibration disc 73 vibrates so as to drive the whole square sleeve charging barrel 71 to vibrate, and the square sleeve 91 is forced to move along the track of the square sleeve track 72 by vibration force; when the square sleeve 91 moves to the vertical channel 74, the square sleeve 91 in a horizontal state under the action of gravity gradually rotates to a vertical state, in the process, as the vertical slots 913 of the square sleeve 91 are not aligned to the vertical channel 74, after the square sleeve 91 completes rotation, the vertical slots 913 of the square sleeve 91 cannot clamp the vertical channel 74 so as to fall down and separate from the vertical channel 74, the vertical slots 913 of the square sleeve 91 in a correct angle are positioned right above the vertical channel 74, and after the square sleeve 91 rotates to the vertical state, the vertical slots 913 of the square sleeve 91 are in clearance to clamp the vertical channel 74, so that the square sleeve 91 has the capability of sliding along the track of the vertical channel 74, and the fact that the rotation mobility of the square sleeve 91 relative to the vertical channel 74 is limited is required, so that two protruding blocks of the square sleeve 91 are always positioned at two sides of the vertical channel 74 in the track sliding process along the vertical channel 74, and the angle adjustment of the square sleeve 91 is realized; when the square sleeve 91 which is vertical and has the right angle slides to the tail end of the vertical plate channel 74, the square sleeve 91 enters the vertical channel 81 under the action of gravity and slides downwards, and enters the horizontal channel 82 when the square sleeve 91 slides to the bottom end of the vertical channel 81, at the moment, the seventh air cylinder 83 pushes the square sleeve 91 to slide along the horizontal channel 82, so that the square sleeve 91 is separated from the square sleeve 91 above, and when the square sleeve 91 slides to the discharge end of the horizontal channel 82, the eighth air cylinder 84 pushes the square sleeve 91 to slide horizontally into a clamping port of a square sleeve clamp 1012 (marked in fig. 2); in summary, the square sleeve 91 is adjusted to be in a vertical state by the vertical plate channel 74, and the square sleeve 91 is limited by the vertical channel 81 and the horizontal channel 82, so that the technical effect of feeding in a vertical and constant-angle state is achieved.

The square sleeve 91 needs to be attached to the inner wall of the Fang Taoliao cylinder 71 and is positioned in the square sleeve rail 72, so that the square sleeve 91 can be spirally lifted due to vibration force and conveniently enter the square sleeve rail 72, as shown in fig. 16, the square sleeve vibration disc 73 is in a round table shape, and the small round surface of the square sleeve vibration disc faces upwards, so that the square sleeve 91 positioned in the square sleeve cylinder 71 is forced to be attached to the inner circumferential surface of the Fang Taoliao cylinder 71 through inclination, and the technical effect that the square sleeve 91 can enter the square sleeve rail 72 more easily is achieved.

In order to reduce the possibility that the square sleeve 91 falls off from the edge of the square sleeve rail 72, the edge of the square sleeve rail 72 is bent and formed with a blocking edge 75, so that the blocking edge 75 blocks the edge of the square sleeve rail 72, and the possibility that the square sleeve 91 falls off is reduced; it should be noted that, when the height of the blocking edge 75 is smaller than the width of the square sleeve 91 and too many square sleeves 91 are stacked at a single position of the square sleeve rail 72, the excessive square sleeves 91 can fall back to the Fang Taoliao cylinder 71 from the edge of the square sleeve rail 72, so as to avoid the occurrence of blocking caused by too many square sleeves 91.

In order to avoid the influence of the mutual interference between the square sleeves 91 on the smooth connection between the square sleeves 91 and the vertical plate channels 74, as shown in fig. 16 and 17, a horizontal narrow channel 741 is arranged between the square sleeve rail 72 and the vertical plate channels 74, the width of the horizontal narrow channel 741 is equal to that of the square sleeves 91, and an outer baffle 76 is formed by bending the outer edge of the horizontal narrow channel 741; when more than one square sleeve 91 simultaneously enters the horizontal narrow channel 741, the redundant square sleeves 91 are pushed away from the horizontal narrow channel 741 due to mutual pushing among the square sleeves 91, so that the square sleeves 91 are arranged by the horizontal narrow channel 741, the technical effect that the square sleeves 91 sequentially enter the vertical plate channel 74 is achieved, and mutual interference among the square sleeves 91 is effectively prevented.

In order to prevent the dropped square sleeve 91 from scattering around, as shown in fig. 17 and 19, the outer circumferential surface of the square sleeve cylinder 71 is welded and fixed with a square sleeve ring 77 under the horizontal narrow channel 741 and the vertical plate channel 74, the cross section of the square sleeve ring 77 is L-shaped, so that the dropped square sleeve 91 is picked up by the square sleeve ring 77, and the square sleeve 91 is prevented from scattering around; it should be noted that, the square sleeve material ring 77 is integrally spirally downward, the square sleeve material barrel 71 is provided with a square sleeve material return window 78, the square sleeve material return window 78 is communicated with the lowest end of the square sleeve material ring 77, the square sleeve 91 to be received is subject to the action of vibration force, slides along the gradient of the square sleeve material ring 77, and falls back to the Fang Taoliao barrel 71 through the square sleeve material return window 78 when sliding to the bottommost end of the square sleeve material ring 77, thereby achieving the technical effect of automatically retracting the dropped square sleeve 91.

In order to avoid the square sleeve 91 from being separated in the process of sliding along the vertical plate channel 74, as shown in fig. 16 and 17, an outer baffle wall 79 and an inner baffle wall 791 are welded and fixed on two sides of the vertical plate channel 74 respectively, and the interval between the outer baffle wall 79 and the inner baffle wall 791 is in clearance fit with the square sleeve 91, so that the square sleeve 91 is limited by the vertical plate channel 74 and is also limited by the fit of the outer baffle wall 79 and the inner baffle wall 791, and the square sleeve 91 is effectively prevented from being separated from the vertical plate channel 74; it should be noted that, a gap section 792 is reserved between the inner baffle wall 791 and the horizontal narrow channel 741, so that the square sleeve 91 with an incorrect angle can fall from the gap section, and further, the inlet end of the vertical channel 74 is prevented from being blocked due to the arrangement of the inner baffle wall 791 and the outer baffle wall 79.

In practical application, it is found that the vertical channel 81 and the horizontal channel 82 may be blocked, for this reason, as shown in fig. 15, 17 and 18, the vertical channel 81 and the horizontal channel 82 are respectively provided with a visual window 85 along the length direction, so that a worker can observe the blocking condition in the vertical channel 81 or the horizontal channel 82 through the visual window 85, and further provide convenience for the worker to make countermeasures in time; the visual window 85 is provided with a transparent plastic strip 86, so that the limiting effect of the vertical channel 81 or the horizontal channel 82 is prevented from being influenced by the visual window 85; it should be noted that, two transparent plastic strips 86 are respectively bolted to vertical channel 81 and horizontal channel 82, so that when the problem of blockage occurs, the worker can detach transparent plastic strip 86 to dredge vertical channel 81 or horizontal channel 82, and further facilitate dredging.

In the process that the square sleeve 91 enters the vertical channel 81 from the vertical channel 74, the moving direction of the square sleeve needs to be changed, so the process belongs to a position easy to drop, and for this reason, as shown in fig. 15 and 17, the connection end of the vertical channel 81 and the vertical channel 74 is welded and fixed with a drop-preventing plate 87 with a U-shaped top view, and the opening of the drop-preventing plate 87 faces the vertical channel 74, so that the drop of the square sleeve 91 is blocked by the drop-preventing plate 87.

The feeding device for the core insert completes the feeding action of the core insert 93 in the following way, as shown in fig. 20, 21 and 22, the feeding mechanism for the core insert comprises a core insert charging barrel 31, a core insert track 32 which spirally ascends along the inner circumferential surface of the core insert charging barrel 31 and a core insert vibration disk 33 which is arranged in the core insert charging barrel 31, the top end of the core insert track 32 is connected with two cylindrical tracks 34 which are arranged in a clearance way, and the distance between the two cylindrical tracks 34 is larger than the diameter of a hollow metal column 931 but smaller than the diameter of a circular ring edge 933; the end of the two cylindrical rails 34 is connected with an angle adjusting assembly, the angle adjusting assembly comprises two rectangular blocks 35 which are arranged in a clearance way, limiting grooves 36 are respectively formed in the upper edges of the opposite faces of the two rectangular blocks 35, the distance between the opposite faces of the two limiting grooves 36 is smaller than the diameter of the circular rim 933, but larger than the maximum distance between the opposite notches 934 (under theoretical conditions, the distance between the two limiting grooves 36 should be equal to the maximum distance between the opposite notches 934).

When the ferrule feeding device works normally, the ferrule vibration disc 33 vibrates, so that the whole ferrule charging barrel 31 is driven to vibrate, and the ferrule is forced to spirally rise along the ferrule track 32 by vibration force; when the ferrule 93 enters between the two cylindrical rails 34, the ferrule 93 rotates under the action of gravity (here, the weight of the hollow metal column 931 needs to be described as being greater than that of the ceramic column 932), so that the hollow metal column 931 passes between the two cylindrical rails 34, and at this time, the annular rim 933 abuts against the two cylindrical rails 34, thereby achieving the technical effect of the vertical ferrule 93; the ferrule 93 in the upright state is subjected to gravity and vibration force to advance along the two cylindrical rails 34; when moving to the junction of the rectangular blocks 35 and the cylindrical rail 34, the circular ring edge 933 of the lock pin 93 with incorrect angle is simultaneously abutted against the feeding end of the limiting groove 36, so that the lock pin 93 cannot enter between the two rectangular blocks 35, when the lock pin 93 rotates to the opposite two notches 934 to align with the opposite surfaces of the limiting groove 36 respectively due to vibration, the lock pin 93 slides into the space between the two rectangular blocks 35, and at this time, the lock pin 93 cannot rotate due to the clamping of the limiting groove 36, so that the angle adjustment of the lock pin 93 is realized.

In practical application, it is found that in the process that the ferrule 93 enters the cylindrical rail 34 from the ferrule rail 32, the problem that the ferrule 93 falls off the rail may occur, as shown in fig. 21 and 23, in order to collect the fallen ferrule 93 conveniently, the outer circumference of the ferrule barrel 31 is provided with a receiving ring 37 with an L-shaped section, so that the removed ferrule 93 is received by the receiving ring 37, the ferrule 93 is effectively prevented from rolling around, and convenience is provided for collecting the fallen ferrule 93; further optimization of the material receiving ring 37 is that the bottom surface of the material receiving ring 37 is obliquely arranged, the material inserting barrel 31 is provided with a material returning window 371, the material returning window 371 is communicated with the lowest end of the material receiving ring 37, so that the insert 93 falling into the material receiving ring 37 slides along the inclination of the material receiving ring 37 under the action of gravity, and finally falls back into the material inserting barrel 31 through the material returning window 371, and the technical effect that a worker is not required to collect the falling insert 93 is achieved.

The two limiting grooves 36 utilize the diameter of the circular rim 933 and the maximum distance between the opposite notches 934, and the difference value of the two limiting grooves realizes the angle adjustment of the ferrule 93, but if the ferrule 93 is in an inclined state as a whole, the angle adjustment is not easy to realize in this way, therefore, as shown in fig. 21 and 22, two rectangular blocks 35 are respectively welded and fixed with limiting rods 38, and the two limiting rods 38 are used for clamping the hollow metal column 931 in a clearance way, so that one end of the hollow metal column 931 is clamped and limited by two cylindrical rails 34, and the other end is clamped and limited by two limiting rods 38, further, the hollow metal column 931 is limited by two ends, and the principle that a straight line is determined by combining two points is effectively prevented from being skewed by the ferrule 93, and further, the problem that the ferrule 93 cannot enter between the two rectangular blocks 35 is avoided.

It should be noted that, in order to facilitate the hollow metal post 931 entering between the two limiting rods 38, as shown in fig. 21, the two limiting rods 38 are arranged in a splayed shape in a top view, and the minimum distance between the two limiting rods is located adjacent to the end of the rectangular block 35, so as to increase the size of the inlet end of the two limiting rods 38, and further facilitate the hollow metal post 931 entering between the two limiting rods 38.

In order to improve the clamping effect of the clamping jaw air cylinder 42, as shown in fig. 21 and 24, two clamping jaws of the clamping jaw air cylinder 42 are vertically and oppositely provided with circular arc grooves 43, when the clamping jaw air cylinder 42 grasps the inserting core 93, the inserting core 93 is positioned in the two circular arc grooves 43, so that the contact area between the clamping jaw air cylinder 42 and the inserting core 93 is increased, and the clamping effect of the clamping jaw air cylinder 42 is further improved.

The feeding device for the core sleeve realizes the feeding action of the core sleeve 92 in the following manner, as shown in fig. 25, 26 and 27, the feeding mechanism for the core sleeve comprises a core sleeve charging barrel 11, a core sleeve vibration disc 12 arranged in the core sleeve charging barrel 11 and a core sleeve channel 13 spirally rising along the inner circumferential surface of the core sleeve charging barrel 11, the top end of the core sleeve channel 13 is communicated with a core sleeve vertical rail 14, the upper surface of the core sleeve vertical rail 14 is provided with a core sleeve channel 15 along the track of the core sleeve vertical rail, the width of the core sleeve channel 15 is larger than the diameter of a small circular section 922 but smaller than the diameter of a large circular section 921, the core sleeve vertical rail 14 is provided with a core sleeve deviation rectifying groove 151 along the upper edges of two sides of the core sleeve channel 15, and the core sleeve deviation rectifying groove 151 is in clearance fit with the large circular section 921.

When the core sleeve feeding device works normally, the core sleeve vibration disc 12 vibrates so as to drive the whole core sleeve charging barrel 11 to vibrate, and the core sleeve 92 placed in the core sleeve charging barrel 11 enters the core sleeve channel 13 under the action of vibration force and rises spirally along the core sleeve channel 13; when the core sleeve 92 enters the core sleeve vertical rail 14, the core sleeve 92 rotates under the action of gravity, so that the small circular section 922 with smaller diameter passes through the core sleeve channel 15, and the large circular section 921 with larger diameter stays on the core sleeve channel 15, and the core sleeve 92 is forced to advance in a vertical state; when the core sleeve 92 moves to the deviation rectifying groove 151, the clamping plates 923 of the core sleeve 92 with incorrect angles are abutted to the upper surface of the core sleeve vertical rail 14, meanwhile, the vibration force of the core sleeve vibration disc 12 is transmitted to the core sleeve vertical rail 14, so that the core sleeve 92 is forced to shake, the core sleeve 92 rotates in the shaking process, when the core sleeve 92 rotates to the clamping plates 923 to be aligned to the deviation rectifying groove 151, the core sleeve 92 falls under the action of gravity, when the clamping plates 923 fall into the deviation rectifying groove 151, the two sides of the clamping plates 923 are clamped by the deviation rectifying groove 151, and therefore the rotation capacity of the core sleeve 92 is limited, and the angle of the core sleeve 92 is adjusted.

The core sleeve 92 needs to be spirally lifted along the core sleeve channel 13, so that the core sleeve 92 enters the core sleeve channel 13 conveniently, as shown in fig. 25, the upper surface of the core sleeve vibration disc 12 is conical, so that the core sleeve 92 is forced to be attached to the inner wall of the core sleeve charging barrel 11, and the technical effect that the core sleeve is easier to enter the core sleeve channel 13 is achieved.

In order to reduce the possibility of falling from the core sleeve channel 13 in the spiral rising process of the core sleeve 92, as shown in fig. 25 and 26, the edge of the core sleeve channel 13 is integrally formed with a blocking wall 16, so that the blocking wall 16 blocks the edge of the core sleeve channel 13, and the possibility of falling from the core sleeve channel 13 of the core sleeve 92 is effectively reduced; however, in practical application, it is found that if all the core sleeves 92 are blocked, the multi-core sleeves 92 are stacked in the core sleeve channels 13, so that a blocking problem is generated, and for this purpose, the height of the blocking wall 16 is smaller than the diameter of the core sleeve 92, so that the core sleeve 92 is blocked to a certain extent, and meanwhile, when the core sleeves 92 at a certain position are stacked too much, the upper core sleeve 92 can be extruded out of the core sleeve channels 13, so that the hidden danger of blocking the core sleeve channels 13 is reduced.

The core sleeve lifting seat 22 is slidably connected with the vertical guide plate 21 in the following manner, as shown in fig. 5, sliding grooves 26 are respectively formed in two sides of the vertical guide plate 21 along the length direction, and two sliding blocks 27 which are respectively embedded in gaps of the corresponding sliding grooves 26 are integrally formed in the core sleeve lifting seat 22, so that the core sleeve lifting seat 22 is slidably connected with the vertical guide plate 21 through cooperation between the sliding blocks 27 and the sliding grooves 26.

In practical application, it is found that, because the outer circumferential surface of the core sleeve 92 is not smooth, there is a problem that the adjacent core sleeves 92 are hooked with each other, in order to avoid that the adjacent core sleeves 92 are driven when the end core sleeve 92 is lifted, as shown in fig. 5 and 6, the vertical guide plate 21 is welded and fixed with a horizontal arm 28, the horizontal arm 28 is installed with a second cylinder 29, the piston rod end of the second cylinder 29 is welded and fixed with a plugboard 291, the core sleeve upright rail 14 is provided with a through slot 292 for inserting the plugboard 291, and the distance from the through slot 292 to the end of the core sleeve upright rail 14 only accommodates one core sleeve 92.

Before the vertical pin 24 is inserted into the inner circle of the core sleeve 92, the second cylinder 29 pushes the insertion plate 291 to pass through the through groove 292, so that the core sleeve 92 at the tail end of the core sleeve vertical rail 14 and the adjacent core sleeve 92 are separated by the insertion plate 291, and further, the situation that the adjacent core sleeve 92 is driven by the vertical pin 24 when the tail end core sleeve 92 is taken away due to the mutual hooking of the adjacent core sleeves 92 is avoided; when the vertical pin 24 brings the end core sleeve 92 away from the core sleeve upright rail 14, the second cylinder 29 controls the insertion plate 291 to retract and disengage from the core sleeve upright rail 14, thereby preventing the next core sleeve 92 from being moved to the end of the core sleeve upright rail 14 by the insertion plate 291.

The disengagement mechanism separates the vertical pin 24 from the core sleeve 92 by, as shown in fig. 5 and 6, comprising a third cylinder 293 fixed to the horizontal arm 28 and a retaining plate 294 fixed to a piston rod end of the third cylinder 293, the retaining plate 294 being abutted against an upper surface of the clamping plate 923; when the vertical pin 24 and the core sleeve 92 are inserted into the core sleeve cylinder 1025 from top to bottom, the third cylinder 293 pushes the retaining plate 294 to move forward to abut against the upper surface of the clamping plate 923, so that the upward mobility of the core sleeve 92 is limited by the retaining plate 294, and when the vertical pin 24 is driven to rise, the core sleeve 92 cannot move upward and is retained in the core sleeve cylinder 1025, so that the separation of the core sleeve 92 and the vertical pin 24 is completed.

It should be noted that, as shown in fig. 5 and 6, the retaining plate 294 is provided with a U-shaped slot 295, and the U-shaped slot 295 is in clearance fit with the large circular section 921, so that when the third cylinder 293 pushes the retaining plate 294 to move forward, the retaining plate 294 is simultaneously abutted against the two clamping plates 923, thereby realizing the technical effect of simultaneously applying downward force to the core sleeve 92 on both sides, and further improving the stress uniformity of the core sleeve 92.

The spring feeding mechanism supplies springs by, as shown in fig. 7, 28 and 29, comprising a spring cylinder 51, a spring rail 52 spirally rising along the inner circumferential surface of the spring cylinder 51, and a spring vibration plate 53 installed in the spring cylinder 51, wherein the top end of the spring rail 52 is connected with a spring pipe 54, and the bottom end of the spring pipe 54 can be communicated with a through hole 58.

During normal operation of the spring feeding device, the spring vibration disc 53 vibrates, so that the spring charging barrel 51 is driven to vibrate, and the spring 94 is forced to spiral up along the spring track 52 by vibration force; when the spring 94 rises to the top of the spring rail 52, it slides under gravity into the spring tube 54 and down the spring tube 54 to engage the upper surface of the telescoping plate 56; simultaneously, the fifth air cylinder 57 pulls the expansion plate 56 to slide to the through hole 58 to be communicated with the spring pipeline 54, so that the bottom end of the spring 94 lacks support and falls into the clamping mouth of the two clamping blocks 59 under the action of gravity, and the two clamping blocks 59 relatively slide to clamp the spring 94; after the clamping of the springs 94 is completed, the fifth air cylinder 57 pushes the expansion plate 56 to slide until the bottom ends of the through holes 58 are aligned to a preset station, and at the moment, the sixth air cylinder 60 pushes the lower pressing column 61 to move downwards, so that lower pressure is applied to the springs 94 by the bottom ends of the lower pressing column 61, and the springs 94 are pushed away from the clamping openings of the two clamping blocks 59 and enter the core sleeve 92 from top to bottom, so that the feeding process of the springs 94 is completed.

The spring rail 52 is communicated with the spring pipeline 54 in the following manner, as shown in fig. 29, the outer circumferential surface of the spring charging barrel 51 is spirally and downwardly fixed with a spring lower sliding rail 62, the top end of the spring lower sliding rail 62 is communicated with the spring rail 52, and the bottom end of the spring lower sliding rail is communicated with the spring pipeline 54, so that the spring rail 52 is communicated with the spring pipeline 54 by the spring lower sliding rail 62, and meanwhile, the speed of the spring 94 can be accelerated by utilizing gravity due to the downward trend of the whole spring lower sliding rail 62, and the technical effect that the spring 94 is easier to be flushed into the spring pipeline 54 is achieved.

In the present invention, the inner diameter of the spring tube 54 is in clearance fit with the springs 94, in order to avoid that more than one spring 94 is crowded at the inlet end of the spring tube 54, as shown in fig. 29, the cross section of the spring lower slide rail 62 is in a semicircular arc with an inner arc surface facing upwards, and the diameter of the inner arc surface is equal to that of the springs 94, so that when more than two springs 94 enter the spring lower slide rail 62 at the same time, the excessive springs 94 will be pushed away from the spring lower slide rail 62, thereby realizing the technical effect of arranging the springs 94 by the spring lower slide rail 62, and effectively avoiding that more than two springs 94 are crowded at the inlet end of the spring tube 54.

In order to prevent the falling spring 94 from rolling in a scattered manner, as shown in fig. 29, a spring receiving ring 63 is welded and fixed on the outer circumferential surface of the spring charging barrel 51 below the spring lower slide rail 62, and the cross section of the spring receiving ring 63 is L-shaped, so that the falling spring 94 is received by the spring receiving ring 63, and the falling spring 94 is prevented from rolling in a scattered manner; it should be noted that, the spring receiving ring 63 is integrally disposed in a spiral downward manner, the spring barrel 51 is provided with a return window 64, and the return window 64 is communicated with the lowest end of the spring receiving ring 63, so that the dropped spring 94 rolls along the gradient of the spring receiving ring 63, and when the spring 94 rolls to the lowest end of the spring receiving ring 63, the spring 94 drops back to the spring barrel 51 through the return window 64, and finally the technical effect of automatically retracting the dropped spring 94 is achieved.

As shown in fig. 7, 28 and 29, in the present invention, the spring tube 54 is a PVC tube, the bottom end of the PVC tube is connected with the spring dividing tube 65, the spring dividing tube 65 is a stainless steel tube in a vertical state, the bottom end of the PVC tube is attached to the upper surface of the expansion plate 56, and when a plurality of springs 94 enter the spring dividing tube 65, the PVC tube is stacked in the spring dividing tube 65 end to end, so that the technical effect of separating the lowermost spring 94 from the upper spring 94 during feeding can be achieved only by ensuring that the distance from the upper opening of the through hole 58 to the upper surface of the rectangular base block 55 is equal to the length of the PVC tube.

In the invention, the spring 94 is clamped in the following manner, as shown in fig. 7, 28 and 29, the control plate 66 is integrally formed on the opposite surfaces of the two clamping blocks 59, and the tension spring 67 is arranged between the control plate 66 and the expansion plate 56, so that the elastic potential energy of the tension spring 67 is utilized to push the two clamping blocks 59 to clamp the spring 94; when the springs 94 drop into the clamping openings of the two clamping blocks 59, the clamping openings of the two clamping blocks 59 are in an open state, for this purpose, the control board 66 is provided with a trapezoid notch 68 which is rectangular trapezoid in plan view, and the upper surface of the rectangular base block 55 is fixedly provided with a supporting column 69, and the supporting column 69 is in abutting fit with the inclined plane of the trapezoid notch 68.

When the expansion plate 56 slides to the position that the through hole 58 is communicated with the bottom end of the spring pipeline 54, the supporting column 69 is abutted on the inclined surface of the trapezoid notch 68 and is subjected to force decomposition to generate outward thrust, so that the two clamping blocks 59 are pushed to slide oppositely, and further the two clamping blocks 59 are opened (at the moment, the tension spring 67 is in a stretching state); when the expansion plate 56 slides towards the predetermined station, the abutment column 69 gradually breaks away from the trapezoid notch 68, so that the tension spring 67 releases elastic potential energy to push the two clamping blocks 59 to move relatively, and clamping of the two clamping blocks 59 is completed.
