Description

Technical Field

[0001] The utility model relates to the technical field of sand - filled pipe processing, in particular to a feeding anti - blocking device for a fiberglass sand - filled pipe. Background Technique

[0002] The fiberglass sand - filled pipe is a new composite material made of resin as the matrix material, glass fiber and its products as the reinforcing material, and quartz sand as the filling material. With its excellent corrosion resistance, hydraulic characteristics, light weight and high strength, large conveying flow rate, convenient installation, short construction period and low comprehensive investment, it has become the best choice for the chemical industry, drainage projects and pipeline projects.

[0003] The patent number CN213767260U discloses a winding device for a fiberglass sand - filled pipe, including an installation device, a winding mechanism, a feeding device, a material receiving device and a discharging device. The feeding device further includes a sand - adding hopper and a sieve plate. One end of the support column is connected to one surface of the sand - adding hopper, and the other end of the support column is connected to one surface of the sand - filled pipe. The sieve plate is installed on the peripheral side of the sand - adding hopper. The sand - filled pipe can transport the raw materials in the sand - adding hopper to the winding mechanism, and the sieve plate can screen out other impurities in the raw materials. However, when feeding, when agglomerates form inside the raw materials, they may not pass through the sieve plate smoothly, causing the sieve plate to be blocked, that is, the raw materials cannot be screened smoothly. And during long - term operation, more and more impurities will accumulate in the sand - adding hopper, and the sieve plate of this device does not have a quick - disassembly function, which is not conducive to the removal of impurities and the maintenance and replacement of the sieve plate.

[0005] The technical solution adopted by the utility model is: a feeding anti - blocking device for a fiberglass sand - filled pipe, including a feeding hopper and a feeding pipe. The lower end of the feeding hopper is slidably matched with the upper end of the feeding pipe. It is characterized in that: a U - shaped sieve plate is arranged inside the feeding hopper, and a plurality of sieve holes are uniformly penetrated through the bottom of the U - shaped sieve plate. The left side wall of the U - shaped sieve plate is detachably and slidably connected with a limiting groove opened on the left inner wall of the feeding hopper. The right side wall of the U - shaped sieve plate is connected with a clamping component, and the clamping component is detachably clamped and matched with an access through - hole opened on the right side wall of the feeding hopper. Between the left and right inner side walls of the lower part of the feeding hopper, an upper rotating rod is rotatably connected through a bearing, and both ends of the upper rotating rod penetrate out of the feeding hopper and are connected with round wheels. Between the left and right inner side walls of the upper part of the feeding pipe, a lower rotating rod is rotatably connected through a bearing, and both ends of the lower rotating rod penetrate out of the feeding pipe and are connected with eccentric cams. Each eccentric cam is in corresponding contact with the round wheel above it.

An upper moving groove is opened in the upper inner part of the clamping cylinder, and the upper moving groove is slidably connected to the upper clamping block, and the top end of the upper clamping block passes through the upper moving groove. To the outside of the clamping cylinder, the top of the upper clamping block is detachably clamped with the clamping groove opened on the inner wall of the in-and-out through hole, a compression spring is vertically arranged in the middle part of the clamping cylinder, the top of the compression spring is connected to the upper clamping block, and the bottom of the compression spring is connected to the lower clamping block, a lower moving groove is opened in the lower part of the clamping cylinder, the lower moving groove is slidably connected to the lower clamping block, and the bottom end of the lower clamping block passes through the lower moving groove to the outside of the clamping cylinder, and the bottom end of the lower clamping block is also detachably clamped with the clamping groove opened on the inner wall of the in-and-out through hole.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model starts the motor to drive the eccentric cam to rotate. The rotation of the eccentric cam will push the round wheel and the feed hopper to move upward, and the support spring will also be deformed. After the round wheel and the feed hopper move upward, they will move downward again due to their own gravity and the elastic force of the support spring. After the round wheel and the feed hopper move downward, they are pushed upward again by the eccentric cam, that is, the feed hopper can move up and down repeatedly and oscillate periodically. The up and down movement and oscillation of the feed hopper loosens the raw materials inside, thereby ensuring the smooth screening of the raw materials and avoiding clogging of the sieve holes to affect the screening efficiency;

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0022] Embodiment

[0023] Please refer to Figures 1 - 4 As shown, a feeding anti-blocking device for a glass fiber reinforced plastic sand-filled pipe in this embodiment includes a feeding hopper 1 and a feeding pipe 2. The lower end of the feeding hopper 1 is slidably engaged with the upper end of the feeding pipe 2. During implementation, the bottom end of the feeding pipe 2 is connected to the winding device body in the background art, which is the prior art and will not be elaborated here. A U-shaped sieve plate 3 is arranged inside the feeding hopper 1. A plurality of sieve holes 4 are evenly penetrated through the bottom of the U-shaped sieve plate 3. The left side wall of the U-shaped sieve plate 3 is detachably and slidably connected to a limiting groove 5 opened on the left inner side wall of the feeding hopper 1. The right side wall of the U-shaped sieve plate 3 is connected with a clamping component 6, and the clamping component 6 is detachably clamped and matched with an access through hole 7 opened on the right side wall of the feeding hopper 1. Between the left and right inner side walls of the lower part of the feeding hopper 1, an upper rotating rod 9 is rotatably connected through a bearing, and both ends of the upper rotating rod 9 penetrate out of the feeding hopper 1 and are connected with round wheels 10. Between the left and right inner side walls of the upper part of the feeding pipe 2, a lower rotating rod 11 is rotatably connected through a bearing, and both ends of the lower rotating rod 11 penetrate out of the feeding pipe 2 and are connected with eccentric cams 12. Each eccentric cam 12 is in corresponding contact with the round wheel 10 above it.

[0024] Further, the clamping component 6 includes an upper shifting rod 61, a lower shifting rod 62, a clamping cylinder 63, a shifting opening 64, an upper clamping block 65, a lower clamping block 66, an upper moving groove 67, a compression spring 68, and a lower moving groove 69. The upper shifting rod 61 and the lower shifting rod 62 are both located in the shifting opening 64 opened on the right side wall of the clamping cylinder 63. The upper shifting rod 61 is connected to the lower right part of the upper clamping block 65, and the lower shifting rod 62 is connected to the upper right part of the lower clamping block 66. An upper moving groove 67 is opened in the upper part of the clamping cylinder 63. The upper moving groove 67 is slidably connected with the upper clamping block 65, and the top end of the upper clamping block 65 penetrates out of the upper moving groove 67 to the outside of the clamping cylinder 63. The top end of the upper clamping block 65 is detachably clamped with a clamping groove 13 opened on the inner side wall of the access through hole 7. A compression spring 68 is vertically arranged in the middle of the clamping cylinder 63. The top end of the compression spring 68 is connected with the upper clamping block 65, and the bottom end of the compression spring 68 is connected with the lower clamping block 66. A lower moving groove 69 is opened in the lower part of the clamping cylinder 63. The lower moving groove 69 is slidably connected with the lower clamping block 66, and the bottom end of the lower clamping block 66 penetrates out of the lower moving groove 69 to the outside of the clamping cylinder 63. The bottom end of the lower clamping block 66 is also detachably clamped with the clamping groove 13 opened on the inner side wall of the access through hole 7.

[0025] It can be understood that when the U-shaped sieve plate 3 needs to be withdrawn or sent into the feed hopper 1 during implementation, the upper lever 61 and the lower lever 62 can be manually toggled so that the upper lever 61 and the lower lever 62 approach each other. At this time, the compression spring 68 is also compressed and deformed, and the fact that the upper lever 61 and the lower lever 62 approach each other will cause both of them to separate from the card slot 13, that is, the U-shaped sieve plate 3 can freely pass through the access hole 7. Conversely, after letting go, the deformed compression spring 68 resets, causing the upper lever 61 and the lower lever 62 to move away from each other and making both of them re-engage with the card slot 13, that is, the U-shaped sieve plate 3 is clamped and fixed. It is worth mentioning that toggling a single upper lever 61 or lower lever 62 will not cause the clamping assembly 6 to release the limit fixation of the U-shaped sieve plate 3, effectively preventing the single upper lever 61 or lower lever 62 from being accidentally touched and causing the U-shaped sieve plate 3 to become loose.

[0026] Furthermore, a support plate is connected to the left side of the feed pipe 2. A support block is connected to the support plate, and a motor 14 is fixedly provided on the support block. The output end of the motor 14 is connected to the eccentric cam 12 at the left end of the lower rotating rod 11. During implementation, the motor 14 is used to provide the power source for the rotation of the eccentric cam 12.

[0027] Furthermore, the cross-sections of both the feed hopper 1 and the feed pipe 2 are square. During implementation, the square cross-sections of the feed hopper 1 and the feed pipe 2 are used to maintain the stability of the feed hopper 1 in the horizontal direction and prevent the feed hopper 1 from rotating by itself.

[0028] Furthermore, a sliding groove 15 is opened at the upper end of the feed pipe 2. The side wall of the sliding groove 15 is slidably connected to the lower end of the feed hopper 1, and a support spring 16 is also connected between the bottom wall of the sliding groove 15 and the bottom end of the feed hopper 1. During implementation, a clamping member for preventing the feed hopper 1 from sliding upward is also provided at the top of the sliding groove 15.

[0029] Furthermore, a handle 17 is connected to the right side wall of the clamping cylinder 63. During implementation, the handle 17 is provided to facilitate taking out or putting into the feed hopper 1 the clamping assembly 6 and the U-shaped sieve plate 3.

[0030] Please refer to Figures 1 - 4As shown in the figure, during use, raw materials are fed from above the feeding hopper 1. After being fed into the U-shaped sieve plate 3 for screening, the motor 14 can be started to drive the eccentric cam 12 to rotate. The rotation of the eccentric cam 12 will push the round wheel 10 and the feeding hopper 1 upward, and the supporting spring 16 will also deform. After the round wheel 10 and the feeding hopper 1 move upward, due to their own gravity and the elastic force of the supporting spring 16 for resetting, they will move downward again. After the round wheel 10 and the feeding hopper 1 move downward, they are pushed upward by the eccentric cam 12 again. That is, the feeding hopper 1 can move up and down periodically and repeatedly for oscillation. The up and down movement and oscillation of the feeding hopper 1 make the inside of the raw materials loose, thus ensuring the smooth screening of the raw materials and avoiding clogging of the sieve holes 4 and affecting the screening efficiency. After working for a long time, more and more impurities will gradually accumulate inside the U-shaped sieve plate 3, and these impurities will affect the normal screening of the raw materials. At this time, the feeding can be paused, and the limit fixation of the U-shaped sieve plate 3 can be released through the clamping component 6. The U-shaped sieve plate 3 can be quickly pulled out of the feeding hopper 1, and the impurities accumulated inside the U-shaped sieve plate 3 can be quickly removed. After removing the impurities, the U-shaped sieve plate 3 can be quickly sent back into the feeding hopper 1 and quickly fixed in position again. That is, the disassembly and assembly of the U-shaped sieve plate 3 are fast and convenient, which is beneficial to the replacement and maintenance of the U-shaped sieve plate 3, saving time and effort.
