Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyethylene cable material processing technology, specifically an anti-clogging feeding device for processing thermoplastic flame-retardant polyethylene cable material. Background Technology
[0002] In the cable material processing, thermoplastic flame-retardant polyethylene (TPE) is widely used in the manufacture of various cables due to its excellent flame-retardant properties and thermoplasticity. However, in actual production, this material is prone to clogging during the feeding process, affecting production efficiency and product quality. When large pieces of TPE cable material or other debris clog the feeding device, the upstream conveying equipment cannot stop in time to continue conveying the TPE cable material. This causes the TPE cable material to overflow around the conveying equipment, crushing or damaging the equipment, leading to production stoppage for cleaning. The clogging of the feeding device not only affects normal production but also increases the workload of on-site cleaning. When clogging occurs, it is not detected in time, which can easily lead to equipment damage.
[0003] Therefore, this utility model provides an anti-clogging feeding device for processing thermoplastic flame-retardant polyethylene cable material to solve the above problems. Utility Model Content

Turntables are fixedly installed on the output shafts at both ends of the dual-axis motor. Connecting rods are rotatably installed on the eccentric circles on opposite sides of the two sets of turntables. Connecting plates are rotatably installed on the lower ends of the two sets of connecting rods. Linkage plates are hinged to the front and rear ends of the two sets of connecting plates. Protrusions are fixedly installed on the left and right sides of the two sets of linkage plates. Two sets of sliding grooves are opened on the inner walls of the left and right sides of the anti-blocking hopper.

[0014] (III) Beneficial Effects
[0015] When the thermoplastic flame-retardant polyethylene cable material falls into the device, the dual-axis motor in the anti-clogging component drives two sets of turntables to rotate. Due to the eccentric design of the turntables, the two sets of connecting rods reciprocate, which in turn drives the connecting plate and the linkage plate to swing back and forth. The linkage plate drives the protrusion to slide in the groove, which in turn causes the two sets of linkage plates to rotate and open on the connecting plate, thereby clearing the blockage of the thermoplastic flame-retardant polyethylene cable material and avoiding the problem of blockage caused by the large-scale feeding of thermoplastic flame-retardant polyethylene cable material. It can ensure the intermittent and small-batch feeding of thermoplastic flame-retardant polyethylene cable material. In addition, the device has a simple structure, is easy to operate and maintain, and can effectively improve production efficiency and product quality, reduce the workload of on-site cleaning, and save costs for enterprises.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] This utility model provides an anti-clogging feeding device for processing thermoplastic flame-retardant polyethylene cable materials, such as... Figure 1-5 As shown, the anti-clogging feeding device for processing thermoplastic flame-retardant polyethylene cable material includes a base 1, a feeding cylinder 2 fixedly installed at the upper end of the base 1, an anti-clogging hopper 3 fixedly installed at the upper end of the feeding cylinder 2, a feeding inlet 4 fixedly installed at the upper end of the anti-clogging hopper 3, a feeding channel 5 opened inside the feeding cylinder 2, a drive motor 6 fixedly installed on the left side of the feeding cylinder 2, a screw conveyor shaft 7 fixedly installed on the output shaft of the drive motor 6, the screw conveyor shaft 7 being rotatably installed in the feeding channel 5, and an anti-clogging component being provided inside the anti-clogging hopper 3.
[0025] In practical applications, the thermoplastic flame-retardant polyethylene cable material enters the device through the inlet 4 and first falls into the anti-blocking hopper 3. The thermoplastic flame-retardant polyethylene cable material can fall smoothly into the discharge cylinder 2. During the downward movement of the thermoplastic flame-retardant polyethylene cable material, it is driven by the anti-blocking component, thereby intermittently discharging the large batch of thermoplastic flame-retardant polyethylene cable material to avoid large-scale blockage at the connection between the discharge cylinder 2 and the anti-blocking hopper 3. Then, the output shaft of the drive motor 6 drives the spiral conveyor shaft 7 to rotate and convey the material.
[0026] The anti-blocking component includes a dual-axis motor 9, which is installed inside the anti-blocking hopper 3. Turntables 10 are fixedly installed on the output shafts at both ends of the dual-axis motor 9. Connecting rods 11 are rotatably installed on the eccentric circles on opposite sides of the two sets of turntables 10. Connecting plates 12 are rotatably installed at the lower ends of the two sets of connecting rods 11. Linkage plates 13 are hinged to the front and rear ends of the two sets of connecting plates 12. Protrusions 14 are fixedly installed on both sides of the two sets of linkage plates 13. Two sets of sliding grooves 16 are opened on the inner walls of both sides of the anti-blocking hopper 3. Four sets of protrusions 14 are slidably inserted into the four sets of sliding grooves 16.
[0027] In practical applications, when the thermoplastic flame-retardant polyethylene cable material falls from above into the feed cylinder 2 and the anti-blocking hopper 3, the output shafts at both ends of the dual-shaft motor 9 are fixedly equipped with turntables 10. The eccentric circle design of the turntables 10 cleverly drives the connecting rods 11 to reciprocate. This reciprocating motion is transmitted through the connecting plate 12 and the linkage plate 13, ultimately causing the protrusions 14 to slide back and forth in the chute 16. When the thermoplastic flame-retardant polyethylene cable material slides down, the reciprocating sliding motion can effectively clear the thermoplastic flame-retardant polyethylene cable material, avoiding large pieces of thermoplastic flame-retardant polyethylene cable material or debris from accumulating in the device and causing blockage.
[0028] A flow diversion guide plate 8 is fixedly installed inside the anti-blocking hopper 3, and a dual-shaft motor 9 is fixedly installed on the lower side of the flow diversion guide plate 8.
[0029] In practical applications, the design of the diversion guide plate 8 plays a key guiding and supporting role, and can shield the upper side of the dual-axis motor 9.
[0030] The upper sides of both the front and rear ends of the diversion guide plate 8 are inclined, and the middle part of the diversion guide plate 8 is higher than the front and rear ends.
[0031] The inclined design of the upper sides of the front and rear ends of the diversion guide plate 8 not only facilitates the smooth sliding of the thermoplastic flame-retardant polyethylene cable material, but also reduces the retention of the thermoplastic flame-retardant polyethylene cable material on the diversion guide plate 8 to a certain extent, thus reducing the risk of blockage.
[0032] Each of the four sets of protrusions 14 is movably mounted with a ball bearing 15, and the four sets of ball bearings 15 are in contact with the inner wall of the four sets of sliding grooves 16.
[0033] In practical applications, the design of the ball bearing 15 further enhances the smoothness of the sliding of the protrusion 14 in the groove 16, while reducing friction and wear during the sliding process and extending the service life of the device. In addition, the ball bearing 15 can also limit the protrusion 14 to a certain extent, preventing it from deviating from the track during the sliding process, thus ensuring the stability and reliability of the device.
[0034] The lower sides of the front and rear ends of the linkage plate 13 are rotatably connected to the lower sides of the opposite ends of the two sets of protrusions 14, and the front and rear sides of the linkage plate 13 are in contact with the opposite sides of the two sets of protrusions 14.
[0035] In practical applications, this rotating connection and fitting design not only enhances the connection stability between the linkage plate 13 and the protrusion 14, but also improves the strength and durability of the entire anti-blocking assembly to a certain extent, so that the linkage plate 13 and the two sets of protrusions 14 can remain tightly fitted when rotating.
[0036] Two sets of limiting rods 17 are fixedly installed on the lower side of the diversion guide plate 8, and the lower ends of the two sets of limiting rods 17 are movably inserted into the left and right ends of the connecting plate 12.
[0037] In practical applications, the design of the limit rod 17 plays a key role in limiting and guiding, ensuring the stability of the connecting plate 12 during reciprocating motion and preventing it from deviating from the predetermined motion trajectory.
[0038] Working principle: During use, the thermoplastic flame-retardant polyethylene cable material enters the device through the feed inlet 4 and first falls into the anti-clogging hopper 3. Due to the inclined design of the diversion guide plate 8, the thermoplastic flame-retardant polyethylene cable material can smoothly fall into the discharge cylinder 2. During the downward movement of the thermoplastic flame-retardant polyethylene cable material, the dual-shaft motor 9 drives two sets of turntables 10 to rotate. Due to the eccentric design of the turntables 10, the two sets of connecting rods 11 reciprocate, thereby driving the connecting plate 12 and the two sets of linkage plates 13 to reciprocate. Two sets of linkage plates 13 drive four sets of protrusions 14 to slide within four sets of sliding grooves 16, thereby causing the two sets of linkage plates 13 to rotate and open on the connecting plate 12, thus realizing the unblocking of large batches of thermoplastic flame-retardant polyethylene cable material and avoiding the problem of blockage caused by large batches of thermoplastic flame-retardant polyethylene cable material. When the thermoplastic flame-retardant polyethylene cable material slides down into the feeding cylinder 2, the output shaft of the drive motor 6 drives the spiral conveying shaft 7 to rotate, conveying the thermoplastic flame-retardant polyethylene cable material from the feeding channel 5.
[0039] 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 equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
