The automatic tube feeder includes a frame, a drive wheel group, a driven wheel group, and a drive assembly for driving the drive wheel group. The automatic tube feeder drives the drive wheel group to move through the drive assembly and transmits the drug-filling tube through the drive wheel group and the driven wheel group, thereby realizing the automatic delivery of the drug-filling tube and thus the automatic filling of the drug hole.

[0004] Although existing tube feeders can deliver the ammunition tube by clamping and rotating the driven wheel set of the drive wheel set, the surface of the ammunition tube is relatively smooth due to the influence of the ammunition adhering to its surface, making it easy to slip during the delivery process and causing inconvenience to the delivery of the ammunition tube.

The double-ended bolt can rotate to move the first connector and the second connector closer or further away.

[0015] In some embodiments, the first tube feeding unit includes a plurality of spaced-apart first clamping wheels, each of which is rotatably connected to the first frame. The second tube feeding unit includes a plurality of second clamping wheels, each of which is rotatably connected to the second frame and is respectively opposite to each of the first clamping wheels.

[0016] In some embodiments, both the first clamping wheel and the second clamping wheel are provided with limiting grooves in the circumferential direction, and the limiting grooves are used to accommodate the medicine tube.

[0017] In some embodiments, the limiting groove is provided with a plurality of spaced-apart ammunition slots in the circumferential direction, and each of the ammunition slots extends toward the axial direction of the first clamping wheel and the second clamping wheel.

[0035] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0036] This invention provides a tube feeding device that solves the technical problem of tube slippage during the tube feeding process in existing drug loading vehicles by adjusting the clamping force of the tube.

[0037] like Figures 1-2 As shown, this utility model provides a tube delivery device, including a first frame 10, a second frame 20, a first tube delivery unit 30, a second tube delivery unit 40, a drive unit 50, and an adjustment unit 60. The second frame 20 is hinged to the first frame 10; the first tube delivery unit 30 is rotatably connected to the first frame 10; the second tube delivery unit 40 is rotatably connected to the second frame 20 and is opposite to the first tube delivery unit 30, forming a tube clamping gap 32 between the second tube delivery unit 40 and the first tube delivery unit 30; the drive unit 50 is connected to the first tube delivery unit 30 and the second tube delivery unit 40, and is used to drive the first tube delivery unit 30 and the second tube delivery unit 40 to rotate; the adjustment unit 60 is connected to the first frame 10 and the second frame 20, and is used to control the rotation of the first frame 10 and / or the second frame 20, and adjust the tube clamping gap 32.

[0038] Specifically, the tube delivery device comprises a first frame 10, a second frame 20, a first tube delivery unit 30, a second tube delivery unit 40, and a drive unit 50. The first frame 10 and the second frame 20 are hinged together. The first tube delivery unit 30 and the second tube delivery unit 40 are rotatably connected to the first frame 10 and the second frame 20, respectively. The second tube delivery unit 40 is opposite to the first tube delivery unit 30 and forms a tube clamping gap 32, which allows the tube to pass through. The drive unit 50 is connected to the first tube delivery unit 30 and the second tube delivery unit 40. By driving the second tube feeding unit 40 and the first tube feeding unit 30 to rotate, the tube in the tube clamping gap 32 can be moved to realize the delivery of the tube. Since the tube feeding device is also equipped with an adjustment unit 60, the adjustment unit 60 can adjust the tube clamping gap 32 by controlling the rotation of the first frame 10 and / or the second frame 20. This allows the clamping force of the first tube feeding unit 30 and the second tube feeding unit 40 to be increased according to the diameter of the tube. Through the above settings, the tube feeding device can adjust the clamping force of the tube, effectively preventing slippage during the delivery of the tube.

[0039] Understandably, the first frame 10 and the second frame 20 can be any frame structure that can accommodate the installation of the first pipe feeding unit 30 and the second pipe feeding unit 40.

[0040] like Figures 1-2 As shown, in this embodiment, both the first frame 10 and the second frame 20 are plate-shaped structures, and the plate-shaped first frame 10 and the second frame 20 are hinged together by hinges.

[0041] Understandably, the tube delivery device can be fixed to the medicine loading cart via the first frame 10, the second frame 20, or other structures such as hinges. When the tube delivery device is fixed via the first frame 10, the adjustment unit 60 can adjust the tube clamping gap 32 by driving the second frame 20. When the tube delivery device is fixed via the second frame 20, the adjustment unit 60 can adjust the tube clamping gap 32 by driving the first frame 10. When the tube delivery device is fixed via a part other than the first frame 10 and the second frame 20, the adjustment unit 60 can adjust the tube clamping gap 32 by simultaneously driving the first frame 10 and the second frame 20.

[0042] Understandably, the adjustment unit 60 can be a spring connected to the first frame 10 and the second frame 20 at both ends respectively, so as to achieve adaptive adjustment of the clamping force of the first tube delivery unit 30 and the second tube delivery unit 40 through the elastic force of the spring, or it can be connected to a driving device such as a cylinder or hydraulic cylinder connected to the first frame 10 and the second frame 20, so as to drive the first frame 10 and / or the second frame 20 to rotate, thereby adjusting the tube clamping gap 32.

[0043] like Figures 1-2 As shown, in some embodiments, the adjustment unit 60 includes a plurality of adjustment frames 61, each adjustment frame 61 being spaced apart along the extension direction of the tube clamping gap 32. One end of each adjustment frame 61 is hinged to the first frame 10, and the other end of each adjustment frame 61 is hinged to the second frame 20. The adjustment frame 61 is used to drive the first frame 10 and / or the second frame 20 to rotate by extending or contracting. Specifically, when the adjustment frame 61 extends, it can drive the first frame 10 and the second frame 20 to open, thereby increasing the tube clamping gap 32. When the adjustment frame 61 shortens, it reduces the clamping force acting on the tube, preventing the tube from deforming, and can drive the first frame 10 and the second frame 20 to move closer, thereby reducing the tube clamping gap 32, increasing the clamping force acting on the tube, and preventing the tube from sliding.

[0044] Understandably, the adjusting frame 61 can be a telescopic rod, or a screw rod with one end hinged to the first frame 10 and the other end threaded to the joint.

[0045] like Figures 1-2 As shown, in some embodiments, the adjusting frame 61 includes a first connector 611, a double-ended bolt 612, and a second connector 613. The first connector 611 and the second connector 613 are arranged opposite to each other and are hinged to the first frame 10 and the second frame 20, respectively. The two ends of the double-ended bolt 612 are threadedly connected to the first connector 611 and the second connector 613, respectively. The double-ended bolt 612 can rotate to move the first connector 611 and the second connector 613 closer or further apart. Specifically, with the above-mentioned arrangement of the adjusting frame 61, when adjusting the drug tube clamping gap 32, only the double-ended bolt 612 needs to be rotated to move the first connector 611 and the second connector 613 closer or further apart. When the first connector 611 and the second connector 613 are closer together, the first frame 10 and the second frame 20 are brought closer together, increasing the clamping force acting on the drug tube. When the first connector 611 and the second connector 613 are further apart, the first frame 10 and the second frame 20 are opened, adaptively reducing the clamping force acting on the drug tube and preventing damage to the drug tube.

[0046] In this embodiment, the first tube feeding unit 30 and the second tube feeding unit 40 can be belts that are rotatably connected to the first frame 10 and the second frame 20, respectively. The driving unit 50 drives the belt to rotate, and then drives the tube to move by the friction of the belt.

[0047] In some embodiments, the first tube feeding unit 30 includes a plurality of spaced-apart first clamping wheels 31, each of which is rotatably connected to the first frame 10. The second tube feeding unit 40 includes a plurality of second clamping wheels 41, each of which is rotatably connected to the second frame 20 and is opposite to each of the first clamping wheels 31. Specifically, during the tube feeding process, the drive unit 50 drives the first clamping wheels 31 and the second clamping wheels 41 to rotate simultaneously in opposite directions. The frictional force exerted by the first clamping wheels 31 and the second clamping wheels 41 on the upper and lower sides of the tube then drives the tube to move, thereby realizing the feeding of the tube.

[0048] like Figures 1-3 As shown, in some embodiments, both the first clamping wheel 31 and the second clamping wheel 41 are provided with limiting grooves 33 in the circumferential direction. The limiting grooves 33 are used to accommodate the medicine tube. Specifically, the limiting grooves 33 can limit the medicine tube, thereby preventing the medicine tube from deviating from the first clamping wheel 31 and the second clamping wheel 41 during the medicine tube transportation process, and ensuring the stability of the medicine tube transportation process.

[0049] In this embodiment, the limiting groove 33 is an arc-shaped structure to fit the medicine tube.

[0050] like Figures 1-3As shown, in some embodiments, the limiting groove 33 is provided with a plurality of spaced-apart ammunition grooves 331 in the circumferential direction, and each ammunition groove 331 extends toward the axial direction of the first clamping wheel 31 and the second clamping wheel 41. Specifically, since ammunition is attached to the surface of the propellant tube, the ammunition groove 331 can accommodate the ammunition on the surface of the propellant tube, thereby removing the ammunition from the surface of the propellant tube. Moreover, the limiting groove 33, through the provision of the ammunition grooves 331, can increase the surface friction of the ammunition grooves 331, thereby preventing the propellant tube from slipping.

[0051] like Figures 1-3 As shown, in some embodiments, the depth of both sides of the ammunition groove 331 gradually decreases along the extension direction of the ammunition groove 331. Specifically, this arrangement of the ammunition groove 331 allows the ammunition in the ammunition groove 331 to gradually overflow from both sides of the ammunition groove 331 under the pressure of subsequent ammunition entering the ammunition groove 331, thereby discharging the ammunition out of the limiting groove 33 and preventing the propellant tube from slipping.

[0052] Understandably, the drive unit 50 can be a structure consisting of a drive component and a transmission component connecting the first clamping wheel 31 and the second clamping wheel 41, thereby enabling simultaneous driving of the first clamping wheel 31 and the second clamping wheel 41. Alternatively, it can be a plurality of drive components respectively connected to each of the first clamping wheel 31 and the second clamping wheel 41.

[0053] like Figures 1-2 As shown, in some embodiments, the drive unit 50 includes a first drive module 51 and a second drive module 52. Both the first drive module 51 and the second drive module 52 include drive members 53 and transmission assemblies 54. The two sets of transmission assemblies 54 are connected to the first clamping wheel 31 and the second clamping wheel 41, respectively. The two sets of drive members 53 are respectively connected to the two sets of transmission assemblies 54, and are used to drive the first clamping wheel 31 and the second clamping wheel 41 to rotate by driving the two sets of transmission assemblies 54. Specifically, the two drive members 53 can drive the first clamping wheel 31 and the second clamping wheel 41 to rotate by driving the two sets of transmission assemblies 54, thereby realizing the delivery of the medicine tube.

[0054] Understandably, the transmission assembly 54 can be a belt sleeved on each of the first clamping wheels 31 and the second clamping wheel 41.

[0055] like Figure 2As shown, in some embodiments, the transmission assembly 54 includes a transmission gear 541, an intermediate connecting gear 542, and a driving gear 543. The transmission gear 541 is connected to each of the first clamping wheels 31 or the second clamping wheels 41. The intermediate connecting gear 542 is located between two adjacent transmission gears 541 and meshes with the two adjacent transmission gears 541. The driving gear 543 is fixed to the driving end of the driving member 53 and meshes with at least one transmission gear 541. Specifically, the driving member 53 drives the driving gear 543 to rotate, which in turn drives the transmission gear 541 meshing with the driving gear 543 to rotate. The other transmission gears 541 rotate synchronously under the transmission of the intermediate gear, ultimately driving each of the first clamping wheels 31 and the second clamping wheels 41. Through the above arrangement of the transmission assembly 54, the structure of the transmission assembly 54 can be significantly enhanced, effectively preventing damage to the transmission assembly 54.

[0056] In this embodiment, the driving component 53 is a motor.

[0057] like Figures 1-2 As shown, in this embodiment, the pipe feeding device further includes a housing 70, which fixes the first frame 10 and the second frame 20. The transmission gear 541, the intermediate connecting gear 542, and the drive gear 543 are all located inside the housing 70, and the drive component 53 is fixed to the housing 70. The housing 70 can protect the transmission gear 541, the intermediate connecting gear 542, and the drive gear 543, effectively preventing damage to the transmission assembly 54.

[0058] like Figure 2 As shown, in this embodiment, the tube feeding device further includes an encoder 80, which is connected to one of the first clamping wheels 31 or one of the second clamping wheels 41, for measuring the rotational speed of the first clamping wheel 31 or the second clamping wheel 41. Specifically, since the encoder 80 is located on the first clamping wheel 31 or the second clamping wheel 41, it can measure the rotational speed of the first clamping wheel 31 or the second clamping wheel 41. Given the radius of the first clamping wheel 31 or the second clamping wheel 41, the tube feeding speed can be obtained, thereby achieving the measurement of the tube feeding speed.

[0059] In this embodiment, the encoder 80 is connected to the first clamping wheel 31 located at the edge.

[0060] The present invention also provides a loading vehicle, including the aforementioned tube delivery device. Specifically, by providing this tube delivery device, the loading vehicle can effectively prevent the tube from slipping, thereby facilitating the delivery of the tube and providing accurate guidance for ammunition filling. At the same time, through the transmission mechanism of the transmission component 54, damage to the transmission component 54 can be avoided, thereby improving the service life of the tube delivery device.

[0061] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
