Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automatic filling, and more specifically, to a filling needle with a shock absorbing device. Background Art
[0002] The main working principle of the filling machine is to drive the filling valve and the bottle inlet and outlet dial wheel through the transmission device to rotate at an appropriate speed. The empty bottles transported through the chain are brought under the filling valve by the bottle inlet dial wheel. After the corresponding filling valve detects the empty bottle, it starts quantitative filling. The liquid enters the empty bottle through the filling needle fixed on the filling needle seat to achieve automatic filling. Therefore, the structural size of the filling needle affects the filling quality of the product. The function of the filling needle is to establish a pipeline passage between the liquid outlet and the body of the empty bottle. The filling needle acts as a drainage pipe to send the liquid into the empty bottle, reduce liquid splashing, and achieve quantitative filling.
[0003] The filling needle structure currently available on the market is extremely simple, made of stainless steel, with the entire needle body integrated and only a drainage pipe structure. The filling needle of the existing filling machine only uses a pipe-like structure (such as Figure 1 As shown in the figure, the upper part of the filling needle is fixed on the filling needle seat and rotates with the filling needle seat at an appropriate speed; when an empty bottle is detected, the filling needle seat moves downward through the transmission structure to insert the filling needle into the empty bottle, so that the liquid enters the empty bottle to achieve filling. When the position of the empty bottle is not completely aligned with the position of the filling needle, the filling needle cannot be completely and accurately inserted into the empty bottle during the descent process, and then the filling needle directly collides with the bottle body, causing the filling needle to be deformed and damaged, and the empty bottle will also be cracked, broken, etc. Therefore, the filling needle structure in the prior art has the technical problem of being easily damaged by collision with the empty bottle and causing the empty bottle to break. Utility Model Content
[0004] The utility model aims to overcome the shortcomings of the prior art that the filling needle structure is easily damaged by collision with an empty bottle and causes the empty bottle to break, and provides a filling needle with a shock absorbing device.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0006] A filling needle with a shock absorbing device comprises a needle body, a shock absorbing structure movably arranged on the needle body and used to abut against a filling bottle mouth, a supporting structure arranged on the needle body and above the shock absorbing structure, and an elastic buffer structure arranged between the shock absorbing structure and the supporting structure, wherein the shock absorbing structure can move along the axial direction of the needle body, and a spacing is provided between the lower end of the needle body and the bottom of the shock absorbing structure.
[0007] The utility model discloses a filling needle with a shock absorbing device, in which a spacing is set between the lower end of the needle body and the bottom of the shock absorbing structure, so that the needle body can be exposed for a certain length, so as to be corrected and aligned with the position of the filling bottle mouth; when the needle body moves downward in the vertical direction of the filling bottle mouth, the shock absorbing structure first abuts against and fits the filling bottle mouth to keep motionless, and as the needle body continues to move downward into the filling bottle, the elastic buffer structure arranged between the shock absorbing structure and the supporting structure will be squeezed to play a buffering effect, and when the position of the filling bottle has a slight deviation, the shock absorbing structure can limit the filling bottle mouth to ensure that the needle body can accurately enter the filling bottle without collision; when the placement position of the filling bottle has a large deviation, once a collision occurs, the uppermost elastic buffer structure plays a limiting buffering role, reduces the downward trend of the needle body, and avoids deformation of the end of the needle body, while the shock absorbing structure below can prevent the bottle body from colliding violently and avoiding damage to the bottle body, thereby effectively solving the technical problem that the filling needle structure in the prior art is easily damaged by collision with the empty bottle and causes the empty bottle to break.
[0008] Furthermore, the shock-absorbing structure includes an upper boss and a lower boss connected to each other, the upper end face of the upper boss abuts against the elastic buffer structure; the outer wall of the lower boss is provided with a taper that smoothly connects the upper and lower end faces, the diameter of the upper end face of the lower boss is larger than the diameter of the filling bottle mouth, and the diameter of the lower end face of the lower boss is smaller than the diameter of the filling bottle mouth. The outer wall of the lower boss is provided with a taper that smoothly connects the upper and lower end faces, and when there is a slight deviation in the placement position of the filling bottle, the downward contact process of the tapered outer wall of the lower boss and the filling bottle mouth can play a guiding role, correct the position of the filling bottle mouth, and allow the needle body to accurately and smoothly enter the filling bottle.
[0009] Furthermore, the shock-absorbing structure further includes an elastic shock-absorbing column connected between the upper boss and the lower boss, and the diameter of the elastic shock-absorbing column is smaller than the diameter of the lower end surface of the upper boss and the diameter of the upper end surface of the lower boss. Since the diameter of the elastic shock-absorbing column is smaller than the diameter of the lower end surface of the upper boss and the diameter of the upper end surface of the lower boss, there is a space between the upper boss and the lower boss for bending in any direction. When the shock-absorbing structure is not aligned with the filling bottle, the shock-absorbing structure will be guided by the body of the filling bottle to bend, so as to avoid the needle body colliding with the bottle body vertically downward when the shock-absorbing structure is not aligned with the filling bottle, and at the same time, the effect of buffering and shock-absorbing in the vertical direction is achieved when a collision occurs.
[0010] Furthermore, a limiting ring is provided on the outer wall of the elastic shock-absorbing column, and a gap is provided between the limiting ring and the upper boss and the lower boss, respectively. A gap is provided between the limiting ring and the upper boss and the lower boss, respectively, to reserve a buffer space and limit shock absorption.
[0011] Furthermore, the diameter of the lower end face of the upper boss, the diameter of the limiting ring and the diameter of the upper end face of the lower boss are all equal. The diameter of the lower end face of the upper boss, the diameter of the limiting ring and the diameter of the upper end face of the lower boss are all set to be equal, so that the overall profile of the shock absorbing structure is cylindrical, which plays the best effect of buffering and shock absorbing.
[0012] Furthermore, the elastic buffer structure is a spring, which has the advantages of light structure, stability, durability and easy installation.
[0013] Furthermore, the diameter of the upper end surface of the upper boss is larger than the diameter of the spring and smaller than the diameter of the lower end surface of the upper boss, and the outer wall of the upper boss is provided with a first conical surface. The first conical surface is provided on the outer wall of the upper boss, and since the diameter of the upper end surface of the upper boss is larger than the diameter of the spring and smaller than the diameter of the lower end surface of the upper boss, the weight is reduced while ensuring the buffering and shock absorbing effect of the structure.
[0014] Furthermore, the outer wall between the upper end face of the upper boss and the top of the first conical surface is a cylindrical surface, and a transition column is provided between the top of the first conical surface and the bottom of the cylindrical surface, and the diameter of the transition column is equal to the diameter of the top of the first conical surface and smaller than the diameter of the cylindrical surface. The outer wall between the upper end face of the upper boss and the top of the first conical surface is set as a cylindrical surface to enhance the structural strength and improve the bearing capacity of the spring; because the diameter of the transition column is equal to the diameter of the top of the first conical surface and smaller than the diameter of the cylindrical surface, it plays a role of separating from the first conical surface, thereby improving the buffering and shock absorbing effect of the upper boss.
[0015] Furthermore, a second conical surface is provided between the bottom of the cylindrical surface and the top of the transition column, the diameter of the upper end surface of the second conical surface is equal to the diameter of the cylindrical surface, and the diameter of the lower end surface of the second conical surface is equal to the diameter of the transition column. A second conical surface is provided between the bottom of the cylindrical surface and the top of the transition column, and since the diameter of the upper end surface of the second conical surface is equal to the diameter of the cylindrical surface, and the diameter of the lower end surface of the second conical surface is equal to the diameter of the transition column, the connection strength with the transition column is enhanced, and the characteristics of buffering and shock absorption are enhanced.
[0016] Further, a spacing is provided between the bottom of the first conical surface and the lower end surface of the upper boss, and the diameter of the bottom of the first conical surface is equal to the diameter of the lower end surface of the upper boss. A spacing is provided between the bottom of the first conical surface and the lower end surface of the upper boss, and the diameter of the bottom of the first conical surface is equal to the diameter of the lower end surface of the upper boss, which plays a role in enhancing the structural strength of the upper boss.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] The utility model discloses a filling needle with a shock absorbing device. When there is a slight deviation in the placement of the filling bottle, the shock absorbing structure limits the filling bottle mouth, thereby ensuring that the needle body can accurately enter the filling bottle without collision. When the placement deviation of the filling bottle is large, once a collision occurs, the uppermost elastic buffer structure plays a limiting buffering role, reducing the downward trend of the needle body and avoiding deformation of the end of the needle body, while the shock absorbing structure below can prevent the bottle body from colliding violently and avoiding damage to the bottle body, thereby effectively solving the technical problem that the filling needle structure in the prior art is easily damaged by collision with the empty bottle and causes the empty bottle to break.

[0025] Embodiment 1
[0026] like Figures 2 to 3 The figure shows a first embodiment of a filling needle with a shock absorbing device according to the utility model.
[0027] A filling needle with a shock absorbing device comprises a needle body 1, a shock absorbing structure 2 movably arranged on the needle body 1 and used to abut against the filling bottle mouth, a support structure 3 arranged on the needle body 1 and arranged above the shock absorbing structure 2, and an elastic buffer structure 4 arranged between the shock absorbing structure 2 and the support structure 3, wherein the shock absorbing structure 2 can move along the axial direction of the needle body 1, and a gap is provided between the lower end of the needle body 1 and the bottom of the shock absorbing structure 2. The shock absorbing structure 2 comprises an upper boss 21 and a lower boss 22 connected to each other, the upper end surface of the upper boss 21 abuts against the elastic buffer structure 4; the outer wall of the lower boss 22 is provided with a taper that smoothly connects the upper and lower end surfaces, the diameter of the upper end surface of the lower boss 22 is larger than the diameter of the filling bottle mouth, and the diameter of the lower end surface of the lower boss 22 is smaller than the diameter of the filling bottle mouth. The shock absorbing structure 2 further includes an elastic shock absorbing column 23 connected between the upper boss 21 and the lower boss 22, and the diameter of the elastic shock absorbing column 23 is smaller than the diameter of the lower end face of the upper boss 21 and the diameter of the upper end face of the lower boss 22. A limiting ring 24 is provided on the outer wall of the elastic shock absorbing column 23, and a gap is provided between the limiting ring 24 and the upper boss 21 and the lower boss 22. The diameter of the lower end face of the upper boss 21, the diameter of the limiting ring 24, and the diameter of the upper end face of the lower boss 22 are all equal.
[0028] In this embodiment, if Figure 2 As shown, a spacing is set between the lower end of the needle body 1 and the bottom of the shock-absorbing structure 2 to ensure that the needle body 1 can be exposed to a certain length, so as to facilitate correction and alignment with the position of the filling bottle mouth; when the needle body 1 moves downward in the vertical direction of the filling bottle mouth, the shock-absorbing structure 2 first abuts against the filling bottle mouth and remains motionless, and as the needle body 1 continues to move downward into the filling bottle, the elastic buffer structure 4 arranged between the shock-absorbing structure 2 and the supporting structure 3 will be squeezed to play a buffering effect. When the position of the filling bottle has a slight deviation, the shock-absorbing structure 2 restricts the filling bottle mouth to ensure that the needle body 1 can accurately enter the filling bottle without collision; when the placement position of the filling bottle has a large deviation, once a collision occurs, the uppermost elastic buffer structure 4 plays a limiting buffering role, reduces the downward trend of the needle body 1, and avoids deformation of the end of the needle body 1, while the shock-absorbing structure 2 below can prevent the bottle body from colliding violently and avoiding damage to the bottle body, effectively solving the technical problem that the filling needle structure of the prior art is easily damaged by collision with the empty bottle and causes the empty bottle to break.
[0029] In addition, in this embodiment, the shock absorbing structure 2 is made of elastic material, such as plastic, rubber, etc.
[0030] In this embodiment, if Figure 3As shown, a taper is provided on the outer wall of the lower boss 22 to smoothly connect the upper and lower end faces. When there is a slight deviation in the placement position of the filling bottle, the downward contact process between the tapered outer wall of the lower boss 22 and the filling bottle mouth can play a guiding role, correcting the position of the filling bottle mouth so that the needle body 1 can accurately and smoothly enter the filling bottle.
[0031] In this embodiment, if Figure 3 As shown, since the diameter of the elastic shock-absorbing column 23 is smaller than the diameter of the lower end surface of the upper boss 21 and the diameter of the upper end surface of the lower boss 22, there is space for bending in any direction between the upper boss 21 and the lower boss 22. When the shock-absorbing structure 2 is not aligned with the filling bottle, the shock-absorbing structure 2 will be guided by the bottle body of the filling bottle to bend, thereby preventing the needle body 1 from colliding vertically downward with the bottle body when the shock-absorbing structure 2 is not aligned with the filling bottle, and at the same time achieving the effect of buffering and shock absorbing in the vertical direction when a collision occurs.
[0032] In this embodiment, if Figure 3 As shown, there are intervals between the limiting ring 24 and the upper boss 21 and the lower boss 22, respectively, which play the role of reserving buffer space and limiting shock absorption.
[0033] In this embodiment, if Figure 3 As shown, the diameter of the lower end surface of the upper boss 21, the diameter of the limiting ring 24 and the diameter of the upper end surface of the lower boss 22 are all set to be equal, so that the overall contour of the shock absorbing structure 2 is cylindrical, achieving the best buffering and shock absorbing effect.

A spacing is provided between the bottom of the first tapered surface 211 and the lower end surface of the upper boss 21, and the diameter of the bottom of the first tapered surface 211 is equal to the diameter of the lower end surface of the upper boss 21.
[0037] In this embodiment, the elastic buffer structure 4 is a spring, which has the advantages of light structure, stability and durability, and easy installation.
[0038] In this embodiment, if Figure 3 As shown, a first conical surface 211 is provided on the outer wall of the upper boss 21. Since the diameter of the upper end surface of the upper boss 21 is larger than the diameter of the spring and smaller than the diameter of the lower end surface of the upper boss 21, it plays a role in reducing weight while ensuring the buffering and shock absorbing effect of the structure.
[0039] In this embodiment, if Figure 3 As shown, a spacing is set between the bottom of the first tapered surface 211 and the lower end surface of the upper boss 21 , and the diameter of the bottom of the first tapered surface 211 is equal to the diameter of the lower end surface of the upper boss 21 , which plays a role in enhancing the structural strength of the upper boss 21 .
[0040] Embodiment 3

Among them, a second tapered surface 213 is provided between the bottom of the cylindrical surface 214 and the top of the transition column 212, and the diameter of the upper end surface of the second tapered surface 213 is equal to the diameter of the cylindrical surface 214, and the diameter of the lower end surface of the second tapered surface 213 is equal to the diameter of the transition column 212.
[0043] In this embodiment, if Figure 3 As shown, the outer wall between the upper end surface of the upper boss 21 and the top of the first conical surface 211 is set as a cylindrical surface 214 to enhance the structural strength and improve the bearing capacity of the spring; because the diameter of the transition column 212 is equal to the diameter of the top of the first conical surface 211 and is smaller than the diameter of the cylindrical surface 214, it plays a role of separating from the first conical surface 211, thereby improving the buffering and shock absorption effect of the upper boss 21.
[0044] In this embodiment, if Figure 3 As shown, a second conical surface 213 is set between the bottom of the cylindrical surface 214 and the top of the transition column 212. Since the diameter of the upper end surface of the second conical surface 213 is equal to the diameter of the cylindrical surface 214, and the diameter of the lower end surface of the second conical surface 213 is equal to the diameter of the transition column 212, it has the effect of enhancing the connection strength with the transition column 212 and enhancing the buffering and shock absorbing characteristics.
