Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a large circular knitting syringe cleaning device. Background Technology

[0002] The circular knitting machine, also known as a circular weft knitting machine, is a core piece of equipment in the textile industry used for mass production of knitted fabrics. The cylinder of the circular knitting machine is a key component that directly determines the knitting precision and finished product quality of the knitted fabric. After the cylinder is produced, it will inevitably leave behind processing impurities such as metal shavings, cutting fluid residue, and grinding dust, so it must be thoroughly cleaned. The existing technology has the following problems: The syringe has a cylindrical structure with an open outer wall, which can quickly remove surface impurities by simply wiping with a brush or cotton cloth, making the cleaning process convenient and efficient; however, the inner wall of the syringe is not only curved but also quite deep, making it difficult for tools such as brushes to penetrate deep into the syringe and fully adhere to the inner wall during manual cleaning, especially near the bottom of the syringe. Due to the dual limitations of operating angle and space, the tools cannot make full contact, and it is necessary to repeatedly adjust the posture and wipe multiple times to clean local areas. This is not only time-consuming and laborious but also easily creates cleaning dead corners, resulting in the residue of impurities such as metal shavings and processing dust, making it difficult to guarantee cleanliness. Utility Model Content

[0003] The purpose of this invention is to provide a large circular knitting machine syringe cleaning device to solve the above-mentioned problems.

[0004] The technical solution of this application is implemented as follows: This application provides a large circular knitting machine syringe cleaning device, including a worktable, brackets fixedly installed on the left and right sides of the worktable, a water filter hole through the top center of the worktable, a fixed seat installed at the top of the worktable corresponding to the position of the water filter hole, and a cleaning device fixedly installed at the front end of the worktable. The cleaning device includes a support plate, which is fixedly welded to the front end of the workbench. An extension plate is fixed to the top of the support plate. The bottom part of the extension plate, avoiding the connection position of the support plate, is suspended above the water filter hole and the fixed seat. A fixed plate is fixedly installed at the front end of the top of the extension plate. A first support plate and a second support plate are fixedly installed from top to bottom at the tail end of the fixed plate. A push rod is fixedly installed at the top of the first support plate. The output end of the push rod passes through the first support plate and is fixedly connected to a ball spline. The middle section of the ball spline is fixedly installed at the top of the second support plate through its outer flange. A round brush is fixedly connected through the bottom of the ball spline through the second support plate. The bottom of the round brush is directly above the filter hole and the fixed seat. A motor is also fixedly installed at the top front end of the extension plate. A pulley is provided at the output end of the motor, and the pulley is connected to the spline sleeve of the ball spline.

[0005] In one embodiment, a water pipe is provided at the front end of the fixed plate, the inlet of the water pipe is connected to a water pump, and the outlet of the water pipe is fixedly connected to a nozzle.

[0006] In one embodiment, the fixing base includes a mounting ring, which is fixedly installed on the top center of the workbench. The top of the mounting ring has a placement groove, and the bottom of the placement groove has a water permeable hole. The water permeable hole corresponds to the water filter hole, and the water filter hole and the water permeable hole are directly opposite the bottom of the round brush. A locking structure is fixedly installed on the outer wall of the mounting ring.

[0007] In one embodiment, the locking structure is provided in two sets, which are symmetrically fixedly installed on the left and right ends of the outer wall of the mounting ring.

[0008] In one embodiment, the locking structure includes a fixing block, which is fixedly installed at either end of the outer wall of the mounting ring, and the bottom of the fixing block is fixedly connected to the top of the workbench. The fixing block has a through mounting hole on the side of the fixing block near the outer wall of the mounting ring, and a waterproof push rod is fixedly installed at the end of the fixing block away from the outer wall of the mounting ring. The output end of the waterproof push rod passes through the mounting hole and is fixedly connected to a limit block.

[0009] In one embodiment, the limiting block has an arc-shaped structure design.

[0010] In one embodiment, a buffer pad is provided on the side of the limiting block near the outer wall of the mounting ring.

[0011] The advantages or beneficial effects of the above technical solutions include at least the following: This application discloses a large circular knitting machine syringe cleaning device. The cleaning device includes a motor, which drives a pulley to rotate a ball spline. At the same time, a push rod drives the ball spline to move up and down axially, so that the circular brush can simultaneously rotate and brush and move up and down. It can penetrate deep into the inner wall of the syringe and cover different depth areas. With the help of the high-pressure water flow from the water pipe nozzle, it can remove stubborn impurities and rinse away debris, thoroughly avoiding dead corners in the inner wall cleaning and solving the problem that it is difficult to guarantee the cleanliness of the inner wall by manual cleaning. Meanwhile, the automated movement of the circular brush and the high-pressure water rinsing are carried out simultaneously in the cleaning process. Compared with repeated manual cleaning, the cleaning time of a single syringe is greatly shortened, which is suitable for the needs of mass production. In addition, this application makes full use of the easy-to-clean feature of the outer wall of the syringe. The equipment only automatically solves the problem of the inner wall. After cleaning, the operator can quickly clean the outer wall. This avoids the cost waste and subsequent maintenance problems caused by excessive automation design and effectively improves economic benefits. Attached Figure Description

[0019] The names of the messages or information exchanged between multiple devices in the embodiments of this application are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0020] Reference Figure 1 A large circular knitting machine for cleaning syringes includes a worktable 1, which provides a stable working platform for syringe cleaning.

[0021] Supports 2 are fixedly installed on the left and right sides of the workbench 1. The supports 2 are used to support the workbench 1 and enhance the structural stability of the workbench 1 so that it can withstand various loads during equipment operation and syringe cleaning process.

[0022] A water filter hole 3 is provided through the top center of the workbench 1. The water filter hole 3 is used to discharge the sewage and waste liquid generated during the cleaning of the syringe in a timely manner, so as to prevent sewage from accumulating on the surface of the workbench 1, and also to help with the centralized treatment of sewage in the future.

[0023] A fixing seat 4 is installed at the top of the workbench 1 corresponding to the opening position of the filter hole 3. It is used to fix the large circular syringe to be cleaned, so that it remains stable during the cleaning process and ensures that the axis of the syringe is aligned with the axis of the cleaning device 5 above.

[0024] A cleaning device 5 is fixedly installed at the front end of the workbench 1. The cleaning device 5 is used to automatically clean the syringe.

[0025] In one embodiment, reference is made to Figure 2 The cleaning device 5 includes a support plate 51, which is fixedly welded to the front end of the workbench 1. The support plate 51 is used to provide stable support for the extension plate 511 and the upper components.

[0026] An extension plate 511 is fixed to the top of the support plate 51. The bottom of the extension plate 511 is suspended above the filter hole 3 and the fixing seat 4, avoiding the connection position of the support plate 51. In this embodiment, the extension plate 511 is fixed to the top of the support plate 51 by welding, and has both support and connection functions. The part of it suspended above the filter hole 3 and the fixing seat 4 can ensure that the subsequent circular brush 57 is accurately aligned with the syringe to be cleaned below.

[0027] A fixing plate 52 is fixedly installed at the top front end of the extension plate 511 for mounting the first support plate 53 and the second support plate 54, and for providing support for the components mounted on them.

[0028] The first support plate 53 and the second support plate 54 are fixedly installed at the tail end of the fixed plate 52 from top to bottom. The first support plate 53 is used to support the push rod 55, and the second support plate 54 is limited and fixed by the outer flange of the ball spline 56. The two work together to provide guidance and support for the axial and rotational movement of the ball spline, ensuring transmission stability.

[0029] A push rod 55 is fixedly installed at the top of the first support plate 53. The push rod 55 drives the ball spline 56 and the bottom circular brush 57 to move up and down along the axis through the telescopic action, thereby causing the circular brush 57 to move up and down on the inner wall of the syringe to clean the inner wall of the syringe in all directions.

[0030] The output end of the push rod 55 is fixedly connected to the ball spline 56 through the first support plate 53. The middle section of the ball spline 56 is fixedly installed on the top of the second support plate 54 through its outer flange. The ball spline 56 can slide axially under the drive of the push rod 55 and rotate under the drive of the spline sleeve, thereby transmitting the rotational power of the motor to the round brush 57 and realizing the lifting and rotation of the round brush 57. It should be noted that ball spline 56 is existing technology, so it will not be described in detail.

[0031] A round brush 57 is fixedly connected to the bottom of the ball spline 56 through the second support plate 54. The bottom of the round brush 57 is directly above the water filter hole 3 and the fixed seat 4. The round brush 57 brushes the impurities on the inner wall of the syringe through rotation. With axial movement, it can extend to different depths of the inner wall of the syringe for cleaning, thereby improving the thoroughness of cleaning. A motor 58 is also fixedly installed at the top front end of the extension plate 511. As a power source, it transmits rotational power through the pulley 59 at the output end, providing driving force for the rotational movement of the ball spline 56 and the circular brush 57.

[0032] The output end of the motor 58 is equipped with a pulley 59, which is connected to the spline sleeve of the ball spline 56. The rotational motion of the motor 58 is transmitted to the ball spline 56 through the belt drive, so that the ball spline 56 can drive the circular brush 57 to rotate and clean the inner wall of the syringe.

[0033] In one embodiment, reference is made to Figure 2 A water pipe 60 is installed at the front end of the fixed plate 52. The water inlet of the water pipe 60 is connected to a water pump, and the outlet is fixedly connected to a nozzle. Water pipe 60 serves as a water delivery channel, using an external water pump to obtain high-pressure water flow, which delivers water or cleaning fluid to the nozzle. The nozzle then sprays the water onto the inner wall of the syringe to be cleaned. The impact force of the high-pressure water flow assists the brush 57 in removing stubborn impurities from the syringe, while also rinsing away the impurities brushed off by the brush 57, preventing secondary adhesion of impurities.

[0034] In one embodiment, reference is made to Figure 3 The fixed base 4 includes a mounting ring 41, which is fixedly installed on the top center of the workbench 1. The mounting ring 41 is used to provide installation positions for the placement groove 42, the water permeable hole 43 and the locking structure 44.

[0035] The top of the mounting ring 41 has a placement groove 42, which is used to hold the large circular syringe to be cleaned. The groove provides radial restraint to the syringe, preventing it from shifting or shaking horizontally during the cleaning process and ensuring the stability of the cleaning position.

[0036] A water-permeable hole 43 is provided at the bottom of the placement groove 42. The water-permeable hole 43 corresponds to the water-filtering hole 3. The water-filtering hole 3 and the water-permeable hole 43 are directly opposite the bottom of the round brush 57. Because the water-permeable hole 43 and the water-filtering hole 3 are directly opposite the bottom of the round brush 57, it can ensure that the impurities generated by the round brush 57 can be discharged directly through the channel with the water flow, avoiding the accumulation of sewage in the placement tank 42 and contamination of the cleaned area.

[0037] A locking structure 44 is fixedly installed on the outer wall of the mounting ring 41. The locking structure 44 further fixes the syringe to be cleaned placed in the top placement groove 42 of the mounting ring 41, so as to prevent the syringe from shaking due to external forces such as the rotation of the round brush 57 and the impact of water flow during the cleaning process.

[0038] Among them, the locking structure 44 is provided in two sets, which are symmetrically fixed and installed on the left and right ends of the outer wall of the mounting ring 41 respectively; Two sets of symmetrical locking structures 44 can apply balanced clamping force from both sides of the syringe, keeping the syringe centered in the placement groove 42, avoiding eccentric displacement of the syringe due to unilateral force, and ensuring that the syringe axis coincides with the rotation axis of the upper circular brush 57.

[0039] In one embodiment, reference is made to Figures 4-5The locking structure 44 includes a fixing block 441, which is fixedly installed on either the left or right end of the outer wall of the mounting ring 41, and the bottom of the fixing block 441 is fixedly connected to the top of the workbench 1. The fixing block 441 is used to provide an installation position for the waterproof push rod 443 and to provide a carrier for the opening of the mounting hole 442.

[0040] The fixing block 441 has a through mounting hole 442 on the side of the outer wall of the mounting ring 41. The mounting hole 442 is used to provide a passage for the output end of the waterproof push rod 443, and at the same time, it guides the extension and retraction movement of the output end of the waterproof push rod 443, ensuring that the limiting block 444 moves accurately in the direction pointing to the syringe.

[0041] A waterproof push rod 443 is fixedly installed on one end of the outer wall of the fixing block 441 away from the mounting ring 41. The waterproof push rod 443 drives the limiting block 444 to move closer to or away from the syringe to be cleaned through the telescopic movement. In this embodiment, the waterproof push rod 443 is a synchronous waterproof push rod, which ensures that the two limit blocks 444 can simultaneously contact the syringe and apply a balanced clamping force. It should be noted that this synchronous waterproof push rod is a known technology. Models such as the electric push rod DT300 or the hydraulic push rod YHG1 can be selected, and the specific model can be adapted and adjusted according to the syringe size and usage specifications.

[0042] The output end of the waterproof push rod 443 passes through the mounting hole 442 and is fixedly connected to the limiting block 444. The limiting block 444 can contact the outer wall of the syringe in the placement groove 42 under the drive of the waterproof push rod 443. By applying clamping force, the syringe is firmly limited in the placement groove 42 to prevent the syringe from being displaced due to the rotation of the round brush 57 and the impact of water flow during cleaning. Among them, the limiting block 444 has an arc-shaped structure design. The large circular syringe itself has a cylindrical structure. The limiting block 444 with the arc structure has a larger contact area with the outer wall of the syringe, which can evenly distribute the clamping force and prevent the syringe from shifting due to uneven local force during cleaning.

[0043] Among them, the limiting block 444 is provided with a buffer rubber pad on the side near the outer wall of the mounting ring 41. The buffer rubber pad has elastic deformation capability. When the waterproof push rod 443 drives the limiting block 444 to clamp the syringe, the rubber pad can offset part of the rigid impact force through its own compression, avoiding the syringe surface indentation and scratch caused by direct rigid contact between the limiting block and the outer wall of the syringe. Meanwhile, the buffer pad can increase the static friction between the limiting block 444 and the outer wall of the syringe, effectively preventing the syringe from shifting due to the rotation of the circular brush 57 and the impact of water flow during the cleaning process.

[0044] Working principle: During operation, the operator first places the syringe to be cleaned into the placement groove 42 at the top of the mounting ring 41 of the fixed base 4. The placement groove 42 first forms a radial limit on the syringe. Then, the locking structure 44, which is symmetrically arranged at both ends of the outer wall of the mounting ring 41, starts to work. The synchronous waterproof push rod 443 on the fixed block 441 is activated. Its output end passes through the mounting hole 442 and pushes the arc-shaped limiting block 444 closer to the outer wall of the syringe. The buffer pad on one side of the limiting block 444 contacts the outer wall of the syringe. This not only applies clamping force evenly through a large contact area to center the syringe and ensures that the syringe axis coincides with the rotation axis of the circular brush 57 of the cleaning device 5 above, but also avoids rigid contact that could damage the syringe surface. At the same time, the buffer pad increases static friction to prevent the syringe from shifting. After the syringe is fixed, the cleaning device 5 and the water pipe 60 start synchronously. The motor 58 at the top of the extension plate 511 in the cleaning device 5 operates, driving the spline sleeve of the ball spline 56 to rotate through the pulley 59 at the output end. At the same time, the push rod 55 on the first support plate 53 extends and retracts, driving the ball spline 56 to slide up and down along the axial direction. The ball spline 56 then drives the round brush 57 at the bottom to rotate and lift at the same time. The round brush 57 extends into the inner wall of the syringe, cleaning the impurities on the inner wall by rotating and brushing, and covering different depth areas of the inner wall of the syringe as it rises and falls, thoroughly cleaning the curved surfaces and bottom of the syringe that are difficult to reach manually. Meanwhile, the water pipe 60 at the front end of the fixed plate 52 obtains high-pressure water flow through an external water pump, and delivers water or cleaning fluid to the nozzle. The water flow will be concentrated and sprayed onto the inner wall of the syringe, using high-pressure impact force to assist the round brush 57 in removing stubborn impurities and rinsing away the brushed impurities to prevent secondary adhesion. Wastewater and impurities generated during the cleaning process are discharged directly into the filter holes 3 through the permeable holes 43 at the bottom of the placement tank 42, which correspond to the filter holes 3, and then discharged from the equipment through the filter holes 3, thus preventing wastewater from accumulating in the placement tank 42 and contaminating the cleaned area. After cleaning is completed, push rod 55 drives round brush 57 to rise and reset, motor 58 stops running, and waterproof push rod 443 retracts to move limit block 444 away from syringe. After the operator takes out syringe, the outer wall can be cleaned quickly because it is easy to clean. Once the cleanliness of the outer wall meets the standard, the entire cleaning operation is completed.
