Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a syringe transporter. Background Technology

[0002] Needle cylinders are a core component of circular knitting machines. Knitting maintenance and cylinder replacement operations involve changing the appropriate needle cylinder to the machine according to production process requirements. This process requires maintenance workers to retrieve suitable needle cylinders from the cylinder storage room, transport them to the machine for replacement, and then return the replaced needle cylinders to the storage area. Because needle cylinders are relatively heavy, maintenance workers need to use tools to move them. However, existing tools present many inconveniences when moving needle cylinders, increasing the workload for staff.

[0003] The existing technology includes a patent CN201410311893.1 entitled Syringe Transport Cart, which uses a screw to control the lifting plate to rise, thereby lifting the syringe and then pushing the syringe away to improve transport efficiency.

[0004] However, in the existing syringe transporter technology, the syringe transporter vibrates during the transport of syringes. The syringe transporter is only equipped with a structure to limit the lower end of the syringe, but not a structure to limit the upper end of the syringe. As a result, when the syringe transporter moves, the syringe will move up and down relative to the clamping plate. The syringe will collide with the clamping plate repeatedly, which will easily damage the edge of the syringe and shorten its service life. Utility Model Content

[0014] As a further improvement to the above technical solution, soft pads are fixed to the end faces of the supporting structure and the upper limit structure that are close to each other.

[0015] As a further improvement to the above technical solution, a lifting component is also included. The lifting component includes a lifting drive structure and a lifting structure. Both the lifting drive structure and the lifting structure are mounted on the vehicle frame. The lifting drive structure drives the lifting structure to move closer to or away from the middle of the vehicle frame.

[0016] As a further improvement to the above technical solution, a lifting roller is rotatably mounted on the front end of the lifting structure.

[0017] As a further improvement to the above technical solution, the lifting roller is adjustablely mounted on the lifting structure, and the lifting roller can be adjusted up and down relative to the lifting structure.

[0029] Needle cylinders are a core component of circular knitting machines. Knitting maintenance and cylinder replacement operations involve changing the appropriate needle cylinder to the machine according to production process requirements. This process requires maintenance workers to retrieve suitable needle cylinders from the cylinder storage room, transport them to the machine for replacement, and then return the replaced needle cylinders to the storage area. Because needle cylinders are relatively heavy, maintenance workers need to use tools to move them. However, existing tools present many inconveniences when moving needle cylinders, increasing the workload for staff.

[0030] The existing technology includes a patent CN201410311893.1 entitled Syringe Transport Cart, which uses a screw to control the lifting plate to rise, thereby lifting the syringe and then pushing the syringe away to improve transport efficiency.

[0031] However, in the existing syringe transporter technology, the syringe transporter vibrates during the transport of syringes. The syringe transporter is only equipped with a structure to limit the lower end of the syringe, but not a structure to limit the upper end of the syringe. As a result, when the syringe transporter moves, the syringe will move up and down relative to the clamping plate. The syringe will collide with the clamping plate repeatedly, which will easily damage the edge of the syringe and shorten its service life.

[0032] This solution was designed to address the aforementioned technical problems.

[0033] Reference Figure 1 and Figure 2 A syringe transport cart includes a frame 100, a first adjustment component 200, a second adjustment component 300, and a lifting component 400.

[0034] The lower end of the frame 100 is equipped with universal casters 110 with brakes to facilitate the movement of the syringe cart by the operator. The frame 100 is provided with a push handle 120, which the operator can operate to move the syringe cart.

[0035] The first adjustment assembly 200 includes a first drive structure 210, a second drive structure 220, a first connecting frame 230, a support structure 240, and a side limiting structure 250.

[0036] The output end of the first drive structure 210 is connected to the first connecting frame 230.

[0037] Both the side limiting structure 250 and the supporting structure 240 are located below the first drive structure 210.

[0038] The side limiting structure 250 extends vertically, and its upper end is slidably connected to the first connecting frame 230. The side limiting structure 250 can slide relative to the first connecting frame 230 in the left-right direction, allowing it to move closer to or further away from the inner side of the frame 100. Specifically, four side limiting structures 250 are arranged in a rectangular pattern. These four structures limit the sides of the syringe. Using four side limiting structures arranged in a rectangular pattern provides better control over the syringe. In this embodiment, the side limiting structures 250 are grouped in pairs, with the two side limiting structures 250 within the same group fixedly connected by a limiting connecting frame 260.

[0039] The number of supporting structures 240 is set to two, and the two supporting structures 240 are arranged in the left-right direction. The supporting structures 240 are fixedly connected to the lower end of the side limiting structure 250. Specifically, in this embodiment, the side limiting structure 250 is equipped with a limiting roller 251, and the side limiting structure 250 and the limiting roller 251 are rotatably connected. The limiting roller 251 can rotate around the vertical axis.

[0040] Specifically, in this embodiment, the limiting roller 251 is disposed in the middle of the side limiting structure 250. The limiting roller 251 is disposed in the middle of the side limiting structure 250 to avoid the flange at the end of the syringe from contacting the limiting roller 251, so that the limiting roller 251 can fully contact the outer peripheral surface of the syringe, thereby enabling the limiting roller 251 to play a better limiting role.

[0041] The output end of the second drive structure 220 is connected to the side limiting structure 250. The second drive structure 220 drives the side limiting structure 250 and the supporting structure 240 to move closer to or away from the center of the syringe transport cart, so that the supporting structure 240 moves closer to or away from the bottom of the syringe.

[0042] The second adjustment component 300 includes a third drive structure 310 and an upper limit structure 320. The third drive structure 310 drives the upper limit structure 320 to move in the vertical direction. The upper limit structure 320 is a plate-shaped component, and a syringe clamping space is formed between the upper limit structure 320 and the support structure 240. By adjusting the positions of the support structure 240 and the upper limit structure 320, the height of the syringe clamping space can be adjusted, thereby adapting to syringes of different specifications.

[0043] Specifically, in this embodiment, the end face of the upper limit structure 320 facing the syringe clamping space and the end face of the support structure 240 facing the syringe clamping space are each provided with a soft pad. By providing a soft pad, the upper and lower ends of the syringe can be prevented from directly contacting relatively hard objects, thereby preventing the end of the syringe from being damaged due to friction with relatively hard objects during transportation, thus effectively protecting the syringe.

[0044] Specifically, in this embodiment, the third driving structure 310, the second driving structure 220, and the first driving structure 210 each include a rotary driving device, a driving threaded sleeve, and a driving screw. The rotary driving device is connected to the driving screw, and the rotary driving device can drive the driving screw to rotate. The driving threaded sleeve and the driving screw are threadedly connected.

[0045] Specifically, in this embodiment, the rotary drive device is configured as a rotating handwheel, and the rotary drive device is fixedly connected to the drive screw. When the worker manually rotates the rotary drive device, it will drive the drive screw to rotate. In other embodiments, the rotary drive device can also be configured as a rotary motor. Those skilled in the art can select the specific structure of the rotary drive device according to actual needs.

[0046] Specifically, the drive screws of both the third drive structure 310 and the first drive structure 210 are configured as screw structures with only one thread. Both drive screws of the third drive structure 310 and the first drive structure 210 extend in the vertical direction. The lower end of the drive screw of the first drive structure 210 is rotatably connected to the first connecting frame 230, and the lower end of the drive screw of the third drive structure 310 is rotatably connected to the upper limit structure 320, thereby enabling the third drive structure 310 and the first drive structure 210 to smoothly drive the supporting structure 240 and the upper limit structure 320 to move vertically, respectively.

[0047] Specifically, in this embodiment, the drive screw of the second drive structure 220 extends in the left-right direction. The drive screw of the second drive structure 220 is configured as a screw structure with two sections of threads with opposite directions of rotation, corresponding to the threads with opposite directions of rotation at both ends. The second drive structure 220 also has two drive threaded sleeves, with the two sections of threads with opposite directions of rotation respectively threadedly connected to the two drive threaded sleeves. The two drive threaded sleeves are respectively fixedly connected to the two limiting connecting brackets 260, so that when the drive screw of the second drive structure 220 rotates, the two limiting connecting brackets 260 move closer to or further away from each other, so that the supporting structure 240 and the side limiting structure 250 move closer to or further away from each other. When the supporting structure 240 abuts against the bottom of the syringe, and the limiting roller 251 of the side limiting structure 250 abuts against the outer peripheral surface of the syringe, it supports and limits the syringe. In other embodiments, the drive screw of the second drive structure 220 may be configured as a screw structure with only one thread, and one of the limiting connecting brackets 260 may be configured to be fixed to the vehicle frame 100 and the other limiting connecting bracket 260 may be configured to be slidably connected to the vehicle frame 100. Those skilled in the art can select the specific structure of the second drive structure 220 according to actual needs.

[0048] Specifically, the lifting component 400 includes a lifting structure 410 and a lifting drive structure 420.

[0049] The number of lifting structures 410 is set to four, and the four lifting structures 410 are arranged in a rectangular arrangement. The lifting structures 410 are grouped in pairs, and the two lifting structures 410 in the same group are fixedly connected by a lifting connecting frame.

[0050] The lifting drive structure 420 includes a lifting drive screw, a lifting drive device, and a lifting drive threaded sleeve. The lifting drive screw has two threads with opposite directions of rotation. The lifting drive device is configured as a rotating handwheel. Two lifting drive threaded sleeves are provided, each fixedly connected to a lifting connecting bracket. When the operator manually operates the lifting drive device, the lifting drive screw rotates, causing the two lifting drive threaded sleeves to move closer to or further away from each other, thus moving the lifting structure 410 closer to or further away from the center of the frame 100.

[0051] Specifically, the end of the lifting structure 410 is provided with a lifting roller 411, which is rotatably connected to the lifting structure 410. The lifting roller 411 is used to engage with the protrusion on the edge of the syringe. The lifting roller 411 can act as an inclined plane, so that the syringe is gradually lifted as the lifting structure 410 approaches the center of the frame 100. It can also prevent the syringe from sliding and rubbing against the inclined plane when the lifting structure 410 approaches the center of the frame 100, thereby effectively preventing syringe wear.

[0052] When the lifting structure 410 approaches the middle of the frame 100, the syringe can be gradually lifted so that it is pre-lifted a certain distance, making it easier for the support structure 240 to move under the syringe. Then, the operator moves the support structure 240 under the syringe using the second drive structure 220. After the support structure 240 is moved under the syringe, the operator gradually raises the support structure 240 using the first drive structure 210, eventually lifting the syringe by the support structure 240.

[0053] Specifically, in this embodiment, the lifting roller 411 is adjustablely mounted on the lifting structure 410. The lifting roller 411 is threadedly connected to the lifting structure 410 via a vertically extending bolt. When the bolt rotates, the lifting roller 411 moves upward or downward relative to the lifting structure 410, thereby adapting to syringes of different sizes. Naturally, a guide assembly is provided between the lifting roller 411 and the lifting structure 410 to guide the lifting roller 411 in the vertical direction, so as to prevent the lifting roller 411 from rotating accidentally.

[0054] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
