[0038] The following further describes the present application in detail with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related utility model and do not limit the utility model. Additionally, it should be noted that for the sake of description, only the parts related to the utility model are shown in the drawings.

[0039] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0040] At least refer to Figures 1 - 7 As shown, the present utility model example provides a head of a computer embroidery machine, and the head includes a machine shell 40, a thread take-up link assembly 20, a transmission mechanism, and an oil circulation device 10.

[0041] The thread take-up link assembly 20 is located above the machine shell 40. The transmission mechanism is located inside the machine shell 40, and the transmission mechanism includes a presser foot link pin 31, a presser foot drive link 32, a presser foot link 33, and a transmission shaft 34.

[0042] As Figure 7 shown, the oil circulation device 10 is used to provide lubricating oil to the positions to be lubricated of the thread take-up link assembly 20, the presser foot link pin 31, the presser foot drive link 32, the presser foot link 33, and the transmission shaft 34, so as to avoid wear on the positions to be lubricated of the thread take-up link assembly 20, the presser foot link pin 31, the presser foot drive link 32, the presser foot link 33, and the transmission shaft 34, and further extend the service life of the thread take-up link assembly 20, the presser foot link pin 31, the presser foot drive link 32, the presser foot link 33, and the transmission shaft 34.

[0043] Among them, as Figure 1 shown, the oil circulation device 10 includes: an oil storage box 11, an oil receiving box 12, and a circulation assembly 13.

[0044] The oil storage box 11 is arranged above the machine shell 40; the oil receiving box 12 is arranged below the machine shell 40.

[0045] The circulation assembly 13 includes an oil pump 131 and an oil suction pipe 132. The oil suction pipe 132 communicates the oil receiving box 12 and the oil storage box 11, and the oil suction pipe 132 pumps the lubricating oil in the oil receiving box 12 to the oil storage box 11 through the oil pump 131. Among them, the oil pump 131 is connected to one of the oil receiving box 12, the oil storage box 11, and the machine shell 40.

[0046] In practical applications, as Figure 1 shown, the oil circulation device 10 further includes a plurality of oil absorption cotton threads 14. One end of each oil absorption cotton thread 14 is inserted into the fixed cotton thread part 113 of the oil storage chamber 111 of the oil storage box 11; the other ends are respectively arranged at the positions to be lubricated of the thread take-up link assembly 20, the presser foot link pin 31, the presser foot drive link 32, the presser foot link 33, and the transmission shaft 34 to provide lubricating oil.

[0047] Through the principle of capillary action, the lubricating oil reaches the positions to be lubricated of the thread picking link assembly 20, the presser foot link pin 31, the presser foot drive link 32, the presser foot link 33 and the transmission shaft 34 through each oil-absorbing cotton thread 14.

[0048] Among them, the lubricating oil dripping from the positions to be lubricated of the thread picking link assembly 20, the presser foot link pin 31, the presser foot drive link 32, the presser foot link 33 and the transmission shaft 34 can drip into the oil receiving chamber 121 of the oil receiving box 12. This avoids the lubricating oil dripping contaminating the fabric.

[0049] The lubricating oil in the oil receiving box 12 can be pumped into the oil storage box 11 by the oil pump 131, enabling the dripping lubricating oil to be reused and avoiding waste of the lubricating oil. Among them, the operation of the oil pump 131 can be controlled by a time relay, so that the lubricating oil in the oil receiving box 12 can be pumped into the oil storage box 11 at preset time intervals.

[0050] As an implementable manner, it further includes sleeves (not shown). Each sleeve corresponds to an oil-absorbing cotton thread 14. The oil-absorbing cotton thread 14 is arranged inside the sleeve, and both ends of the oil-absorbing cotton thread 14 extend out of the sleeve.

[0051] The sleeves can be heat-shrinkable tubes, corrugated tubes, etc. Each oil-absorbing cotton thread 14 passes through the sleeve, and both ends of the oil-absorbing cotton thread 14 extend out of the sleeve. The arrangement of the sleeves avoids the lubricating oil on the oil-absorbing cotton thread 14 accidentally dripping onto the fabric.

[0052] Furthermore, the length of the end of the oil-absorbing cotton thread 14 extending out of the sleeve in the oil storage chamber 111 of the oil storage box 11 is relatively long, which helps to generate capillary action, thereby improving the lubrication effect of each position to be lubricated.

[0053] As an implementable manner, the oil storage box 11 further includes a tee joint 112 and a first support member 113. The oil circulation device 10 further includes a first filter felt 151. The first filter felt 151 is arranged in the oil storage chamber 111 through the first support member 113.

[0054] As Figure 2 and Figure 3 shown, the oil pump 131 is connected to the oil storage box 11 and is located on the outer surface of the side wall of the oil receiving chamber 121.

[0055] A first support member 113 is arranged in the oil storage chamber 111. The first support member 113 is connected to the bottom of the oil storage chamber 111. The first support member 113 supports the first filter felt 151, and the first filter felt 151 is suspended.

[0056] A three-way joint 112 is connected above the opening of the oil storage chamber 111. The first joint of the three-way joint 112 is connected to the oil inlet pipe, and the second joint is connected to the oil outlet pipe; the third joint is arranged facing the first filter felt 151, so that the lubricating oil flowing out from the third joint passes through the first filter felt 151, and the third filter felt 153 can filter the lubricating oil flowing out from the third joint, avoiding impurities in the lubricating oil reaching the position to be lubricated and affecting the lubrication effect.

[0057] At the same time, the opening where the oil suction pipe 132 communicates with the oil storage chamber 111 corresponds to the first filter felt 151, so that the lubricating oil flowing out from the opening where the oil suction pipe 132 communicates with the oil storage chamber 111 passes through the first filter felt 151. In this way, the third filter felt 153 can filter the lubricating oil flowing out from the oil suction pipe 132, avoiding impurities in the lubricating oil reaching the position to be lubricated and affecting the lubrication effect.

[0058] In addition, the three-way joint 112 can be controlled to work by a time relay, and oil is supplied to the inside of the oil storage chamber 111 regularly to ensure the stable operation of the oil circulation system.

[0059] As an implementable mode, the oil receiving box 12 is provided with an oil receiving chamber 121 and an oil collecting chamber 122. The oil receiving chamber 121 and the oil collecting chamber 122 are communicated, and the oil receiving chamber 121 is higher than the oil collecting chamber 122.

[0060] As Figures 4 - 6 shown, the oil receiving box 12 has a cavity structure, and a second filter felt 152 is arranged in the cavity structure. The second filter felt 152 is connected by a first connecting piece 123. The second filter felt 152 divides the cavity structure into an oil receiving chamber 121 and an oil collecting chamber 122. Among them, the oil receiving chamber 121 is higher than the oil collecting chamber 122, and the oil collecting chamber 122 is communicated with the oil storage chamber 111 through an oil suction pipe 132. One end of the oil suction pipe 132 located in the oil collecting chamber 122 is fixed in the oil collecting chamber 122 through a second connecting piece 124.

[0061] The second filter felt 152 can purify the dripping lubricating oil, avoiding impurities in the dripping lubricating oil from affecting the lubrication effect.

[0062] In addition, as Figure 4 shown, a third filter felt 153 is also arranged in the oil collecting chamber 122. The third filter felt 153 can further purify the impurities in the dripping lubricating oil.

[0063] This embodiment also provides a computerized embroidery machine, including a machine head having the above-mentioned oil circulation device 10. This computerized embroidery machine has the following advantages:

[0064] The lubricating oil in the oil receiving box 12 can be pumped into the oil storage box 11 by the oil pump 131, so that the dripping lubricating oil can be reused, avoiding the waste of lubricating oil. Among them, the operation of the oil pump 131 can be controlled by a time relay, so that the lubricating oil in the oil receiving box 12 can be pumped into the oil storage box 11 at preset time intervals.
