Referring to fig. 1 and 2, there is shown a syringe slide apparatus according to an embodiment of the present application, including: a slide body 10 and an air-assisted acceleration assembly 20. The slideway body 10 is used for arranging the needle cylinders in sequence and transferring the needle cylinders to the rotating wheel main body one by one, so that the needle cylinders can be assembled with the needle bars in a matching way. The pneumatic conveying accelerating assembly 20 is used for endowing the slideway body 10 with a pneumatic conveying function, and the moving speed of the needle cylinder in the slideway body 10 is accelerated in a blowing mode.

Specifically, the slide way body 10 is a long strip body and is obliquely arranged on the periphery of the rotating wheel main body, and the slide way body 10 is provided with a downward sliding channel 11 and an installation through hole which are communicated with each other; the air supply accelerating assembly 20 comprises an air supply block 21, the air supply block 21 is clamped in the installation through hole, an air supply channel communicated with the lower sliding channel 11 is arranged on the air supply block 21, and an air outlet of the air supply channel faces to an outlet of the lower sliding channel 11.

When the needle cylinder slideway device is used for feeding a needle cylinder, the slideway body 10 is arranged in an inclined posture, so that the needle cylinder can slide along the sliding channel 11 through the self gravity, an additional power mechanism is not required to be arranged, the structure of the device is simpler, and the manufacturing and using cost is lower. Because the air supply accelerating assembly 20 is designed and installed on the slide way body 10, specifically, the air supply block 21 is clamped and installed in the installation through hole preset on the slide way body 10, so that the air supply channel preset on the air supply block 21 is communicated with the lower slide channel 11, and the air outlet of the air supply channel is arranged towards the outlet of the lower slide channel 11. So, when the cylinder slided to the gas outlet position, the air current of erupting can promote the cylinder and slide downwards with higher speed to can effectively overcome defects such as sliding resistance, manufacturing dimension error and lead to the problem that cylinder landing speed can't match the rotational speed of runner main part, make the cylinder accurate, reliably slide in the material recess of getting in the runner main part, avoid the cylinder card material phenomenon to take place, guarantee that equipment operation is safe, smooth and easy.

Referring to fig. 1, fig. 3 and fig. 4, in an embodiment, the chute body 10 includes a first baffle 12 and a second baffle 13 that are symmetrically spaced apart from each other, and the sliding channel 11 is formed between the first baffle 12 and the second baffle 13. The first shutter 12 and the second shutter 13 are fixed by being mounted on a lower support, so that the shape and size of the slide passage 11 can be maintained. The first baffle plate 12 and the second baffle plate 13 are both provided with the mounting through holes, and one air supply block 21 is clamped in each mounting through hole; the air supply accelerating assembly 20 further comprises an air source and an air pipe, one end of the air pipe is communicated with the air source, and the other end of the air pipe is communicated with the air supply channel. Basically, the needle cylinder can be accelerated by adopting a unilateral blowing mode. However, in the embodiment, the air is symmetrically blown from two sides, so that the air blowing power borne by two sides of the needle cylinder is more stable and balanced, and the needle cylinder is prevented from inclining to one side and being excessively contacted and rubbed with the side wall of the slideway; in addition, double-side blowing is adopted, and the sliding of the needle cylinder can be further accelerated.

Preferably, in an embodiment, the air supply channel includes a plurality of air outlets opened on the air supply block 21, and the plurality of air outlets are arranged side by side at intervals along the sliding direction of the downward sliding channel 11. So, a plurality of gas outlets can continuously blow to the cylinder, make the cylinder can keep continuously accelerating the slip state to furthest eliminates the resistance influence of friction slide lateral wall when moving in gliding passageway 11 down.

More preferably, for the purpose of combining the manufacturing cost and the air blast accelerating effect, the plurality of air outlets are preferably arranged in a section of the stroke close to the outlet of the downward sliding channel 11, for example, in a 60cm section of the stroke. So that the needle cylinder is accelerated in a period of time just before leaving the glide path 11.

It should be noted that due to the boundary resistance effect of the air flow, the object may be subjected to a certain blocking force when approaching the air flow. Therefore, in order to reduce the resistance effect on the needle cylinder, the arrangement mode of the plurality of air outlets is optimally designed, that is, the arrangement density of the air outlets changes from sparse to dense along the sliding direction of the lower sliding channel 11, and the air outlet flow of the air outlets presents an increasing trend. This makes when the cylinder landing in-process, the gas outlet of contact earlier because the density of arranging is low and the flow of giving vent to anger is less for the air current boundary resistance that the cylinder receives is little, therefore gets into in the air-assisted acceleration district more easily, and when further sliding in the air-assisted acceleration, increases gradually along with the density of arranging of gas outlet, and the flow of giving vent to anger presents and increases progressively, and the sliding speed of cylinder can realize progressively linear increasing progressively, when guaranteeing acceleration effect, can also guarantee that the cylinder removes steadily.

In addition, in order to avoid the disturbance of the high-speed airflow to the syringe, which may cause the syringe to jump and fall off the lower slide channel 11, in an embodiment, a first step is concavely provided on the top surface of the first baffle 12 along the sliding direction, a second step is concavely provided on the top surface of the second baffle 13 along the sliding direction, and the first step and the second step cooperate to form a limiting groove. At the moment, the limit groove formed by the first step and the second step can limit the contact of two sides of the needle cylinder, so that the freedom degree of the needle cylinder is limited to a certain extent, and the phenomenon that the needle cylinder jumps violently to jump off the slide way is avoided.

With continuing reference to fig. 1 to 3, or as an alternative to the above embodiment, the syringe slide device further includes a bracket 30 mounted on the first baffle 12 and/or the second baffle 13, and a pressing plate 40 mounted on the bracket 30, wherein the pressing plate 40 is disposed right above the lower slide path 11. The pressing plate 40 can contact with the top surface of the needle cylinder in the lower slide passage 11 or form a slight gap, so that the needle cylinder is restrained from jumping longitudinally and is prevented from jumping out of the lower slide passage 11.

More preferably, the length of the pressure plate 40 is greater than or equal to the distribution length of all the air outlets. That is, the length of the longest connecting line of the plurality of air outlets is less than or equal to the length of the pressing plate 40, so that the stable and safe accelerated movement of the needle cylinder in the air conveying acceleration zone can be ensured.

In the actual production process, the injector product needs to be assembled by two raw materials, namely a needle rod and a needle cylinder, so that when the equipment idles or the needle rod is short of feeding due to special reasons, the feeding of the needle cylinder needs to be stopped, namely, the needle cylinder needs to be prevented from sliding out of the lower sliding channel 11. With continuing reference to fig. 1 and fig. 4, therefore, in a further embodiment, the syringe slide device further includes a material blocking cylinder 50 disposed on the slide body 10, wherein a piston rod of the material blocking cylinder 50 can be in open-close fit with an outlet of the lower slide channel 11; or still include the striker assembly, the striker assembly including keep off material cylinder 50 and with the striker plate that keeps off material cylinder 50 is connected, the striker plate can with the cooperation is opened and close in the export of gliding passageway 11. Therefore, when the piston rod or the material baffle plate is driven by the air cylinder 50 to shield the outlet of the gliding channel 11, the needle cylinder can be effectively prevented from sliding out; when the normal production is recovered, the air cylinder 50 is only controlled to recover the piston rod, the outlet of the sliding channel 11 can be opened at the moment, and the needle tube can continuously slide out to realize feeding.

Of course, in other embodiments, other structures may be used to temporarily store and slide the needle cannula in the downward sliding channel 11. For example, a first electromagnet is mounted on one side of the outlet, and a second electromagnet is mounted on the other side of the outlet through a spring. When the needle tube is electrified, the first electromagnet can be attracted with the second electromagnet, the spring is stretched to block the outlet, and the needle tube cannot continuously slide out. When the power is off, the first electromagnet and the second electromagnet are disconnected due to the loss of magnetic attraction, the second electromagnet is retracted under the resilience force of the spring, the spring opens the outlet, and the needle tube can normally slide out of the lower sliding channel 11.

With reference to fig. 1, fig. 2 and fig. 4, in addition, in another embodiment, the syringe slide apparatus further includes a blocking electric eye 60, and the blocking electric eye 60 is disposed on the slide body 10 and located near the entrance of the lower slide channel 11. When the feed rate of slide is greater than the material speed of getting of runner main part, and lead to the cylinder to pile up when gliding passageway 11 under, in order to avoid the cylinder to pile up too big, extrusion damage each other, retardant electric eye 60 can in time detect the cylinder and pile up to be detained in gliding passageway 11 under to feedback signal gives the controller, and the controller just can stop the vibration dish and continue the material loading, prevents to appear above-mentioned problem.

Further, in an embodiment, the syringe slide device further includes a material-reducing electric eye 70, and the material-reducing electric eye 70 is disposed on the slide body 10 and located at the outlet close to the lower slide channel 11. So, when few material electric eye 70 can not detect the cylinder, then show that the cylinder quantity of reserving in the gliding passageway 11 is too big, for guaranteeing to last the feed, ensures machining efficiency and continuity, few material electric eye 70 can in time feedback signal for the controller, the controller alright drive vibration dish in time supply cylinder in the gliding passageway 11, perhaps the controller control alarm sends the police dispatch newspaper, reminds the staff in time to carry out the feed supplement.

As mentioned above, when the sliding speed of the needle cylinder in the downward sliding channel 11 is lower than the rotating speed of the rotating wheel body, the needle cylinder is blocked at the outlet because the needle cylinder cannot slide into the material taking groove, if the needle cylinder is further pressed by the rotating wheel body, the needle cylinder will burst, and fragments will be scattered to other mechanical mechanisms, so that there is a great potential safety hazard. In view of this, a self-protection function is designed for the device. In an embodiment, the needle cylinder slide device further includes a material blocking protection assembly 80, wherein the material blocking protection assembly 80 includes a connection seat 81 disposed on the slide body 10 and located on one side of the outlet of the downward sliding channel 11, a material blocking electric eye 82 disposed on the connection seat 81, and a limiting block 83 movably disposed on the connection seat 81 and capable of being triggered and matched with the material blocking electric eye 82. When the needle cylinder cannot slide into the material taking groove and is extruded and pushed by the rotating wheel main body, the needle cylinder can be extruded towards one side of the outlet of the downward sliding channel 11; at this moment, the syringe extrusion limiting block 83 slides on the connecting seat 81, when the syringe extrusion limiting block is moved to trigger the material clamping electric eye 82, the material clamping electric eye 82 can immediately feed back a signal to the controller, the controller can control the rotating wheel main body to stop rotating, and the syringe is protected from further extrusion and bursting.

It will be appreciated that the small charge electric eye 70 and the card charge electric eye 82 are conventional detection devices in the art, such as infrared sensors, which can be triggered and feed back a signal to the controller when the emitted infrared light is blocked. Wherein, the controller can be a PLC device, a micro-control computer and the like.

With reference to fig. 1, fig. 3 and fig. 4, in a further embodiment, the material jamming protection assembly 80 further includes a guiding sliding seat 84, a guiding shaft extends from a side surface of the connecting seat 81, a stop ring 85 is disposed at an end of the guiding shaft away from the connecting seat 81, and the guiding sliding seat 84 is slidably sleeved on the guiding shaft and can be in limit abutment with the stop ring 85. In this way, the stopper ring 85 can restrict the guide slide 84 from coming off the guide shaft when it is retracted to the limit position.

Furthermore, the material jamming protection assembly 80 further comprises an elastic resetting member 86, one end of the elastic resetting member 86 is connected with the connecting seat 81, and the other end of the elastic resetting member 86 is connected with the guiding sliding seat 84. The elastic reset piece 86 can enable the guide sliding seat 84 to reset automatically, namely, the limiting block 83 resets automatically, so that the limiting block 83 can accurately detect the next potential needle cylinder with a stuck plug.
