Description

Technical Field

[0001] The present invention relates to the technical field of resin bulk density measurement, and specifically to a bulk density tester for resin production. Background Art

[0002] In resin production, a bulk density tester is an important device for evaluating the physical properties of materials, mainly used to measure the density of resin powder or particles in a natural bulk state.

[0003] The bulk density of aggregates can be divided into natural bulk density, tapped density, and compacted density. The natural bulk density is measured by freely falling aggregates into a measuring cylinder, the tapped density is measured by manually tapping or mechanically vibrating the measuring cylinder, and the compacted density is measured by manually tamping the aggregates in the measuring cylinder with a tamping rod.

[0004] When measuring the tapped density with existing bulk density testers, it is necessary to first fill the measuring cylinder with materials and then vibrate them. After the materials are tamped, additional materials are added until they exceed the mouth of the measuring cylinder. The particles protruding from the mouth of the measuring cylinder are scraped off, and then the tamped measuring cylinder is manually placed on a scale for weighing. Then, manually transferring the measuring cylinder easily causes the materials at the mouth of the measuring cylinder to fall due to hand tremors, resulting in data deviation and inconvenient use. Summary of the Invention

[0005] (I) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the present invention provides a bulk density tester for resin production, which solves the problems mentioned in the above background art.

[0007] (II) Technical Solutions

[0008] To achieve the above objectives, the present invention is realized through the following technical solutions: A bulk density tester for resin production includes a base and a measuring cylinder. A weighing mechanism for weighing the weight of resin particles and a vibration mechanism for tamping the resin particles are provided on the top of the base. A transfer mechanism for transferring the measuring cylinder from the vibration mechanism to the weighing mechanism is provided between the weighing mechanism and the vibration mechanism.

[0009] Preferably, the weighing mechanism is set as an electronic scale.

[0010] Preferably, the vibration mechanism includes a slide bar, a spring, a mounting seat, a slider, a vibration seat, and a driving component. A slot matching the measuring cylinder is provided on the vibration seat. The bottom of the vibration seat is fixedly connected with the slider, and the slider is slidably matched with the slide bar. Both ends of the slide bar are fixedly connected with mounting seats, and the bottom of the mounting seat is fixedly connected with the base. The spring is arranged between the slider and the mounting seat. A driving component for enabling the vibration seat to reciprocate along the slide bar is provided on one side of the vibration seat.

[0011] Preferably, the driving assembly includes a driving motor and an eccentric wheel. The driving motor is fixedly connected to the base. An eccentric wheel is arranged above the driving motor. The output end of the driving motor is fixedly connected to the eccentric wheel. The eccentric wheel is in mutual contact with the vibration seat.

[0012] Preferably, the transfer mechanism includes an electric turntable, a first electric push rod, a second electric push rod, a connecting block, and a transfer fork. The electric turntable is installed on the base. The top of the electric turntable is fixedly connected to a vertically arranged first electric push rod. The top of the first electric push rod is fixedly connected to a connecting block. One side of the connecting block is fixedly connected to a horizontally arranged second electric push rod. The output end of the second electric push rod is fixedly connected to a transfer fork. The transfer fork is set in a U shape and is matched with the measuring cylinder.

[0013] Preferably, a protruding ring is fixedly connected to the outer side of the top of the measuring cylinder. The protruding ring is matched with the transfer fork. When the transfer fork abuts against the measuring cylinder and rises, the top of the transfer fork will abut against the protruding ring. When the transfer fork continues to rise, it will drive the measuring cylinder to rise.

[0014] Preferably, it further includes a protection ring for preventing resin particles inside the measuring cylinder from falling during the transfer process. The protection ring includes an outer ring, a top limiting ring, and a bottom limiting ring. The top limiting ring is arranged above the protruding ring. The bottom limiting ring is arranged below the protruding ring. The top of the outer ring is fixedly connected to the top limiting ring. The bottom of the outer ring is fixedly connected to the bottom limiting ring. When the transfer fork abuts against the measuring cylinder and rises, the top of the transfer fork will first abut against the bottom limiting ring. Then, as the transfer fork rises, the bottom limiting ring drives the outer ring to rise, making the outer ring higher than the upper edge of the measuring cylinder until the bottom limiting ring abuts against the bottom of the protruding ring. When the transfer fork continues to rise, it will drive the measuring cylinder to rise, so that the outer ring will be higher than the mouth of the measuring cylinder during the transfer, ensuring that the resin particles in the measuring cylinder will not fall.

[0015] Preferably, it further includes an anti-slip assembly for preventing the measuring cylinder from sliding out of the transfer fork by using the gravity of the measuring cylinder. The anti-slip assembly includes a first airbag, a second airbag, a connecting pipe, a pressing plate, and a resilient member. The first airbag is fixedly connected to the top of the bent part of the transfer fork. The top of the first airbag is fixedly connected to a pressing plate. Both ends of the pressing plate are fixedly connected to resilient members. The bottom of the resilient members is fixedly connected to the transfer fork. The second airbag is fixedly connected to the inner side of the straight part of the transfer fork. A connecting pipe is fixedly connected between the first airbag and the second airbag. When the transfer fork transfers the measuring cylinder, the weight of the measuring cylinder and the resin particles presses on the pressing plate, causing the pressing plate to descend and press the gas in the first airbag into the second airbag. The second airbag bulges and clamps the side of the measuring cylinder to prevent the measuring cylinder from slipping out of the straight part of the transfer fork.

[0016] (III) Beneficial effects

[0029] The embodiment of the present invention provides a bulk density tester for resin production, as Figures 1-8 shown, including a base 1 and a measuring cylinder 4. A weighing mechanism 2 for weighing the weight of resin particles and a vibration mechanism 3 for vibrating and compacting the resin particles are provided on the top of the base 1. A transfer mechanism 5 for transferring the measuring cylinder 4 from the vibration mechanism 3 to the weighing mechanism 2 is provided between the weighing mechanism 2 and the vibration mechanism 3.

[0030] Through the setting of the transfer mechanism 5, during use, the first electric push rod 14 extends and retracts to adjust the height of the transfer fork 17, the electric turntable 13 adjusts the orientation of the transfer fork 17, and then the second electric push rod 16 is used to make the transfer fork 17 abut against the barrel of the measuring cylinder 4. Then, the first electric push rod 14 is turned on. When the first electric push rod 14 extends and drives the transfer fork 17 to rise, when the transfer fork 17 abuts against the measuring cylinder 4 and rises, the top of the transfer fork 17 will abut against the protruding ring 26, so that when the transfer fork 17 continues to rise, it drives the measuring cylinder 4 to rise, so that the measuring cylinder 4 comes out of the slot of the vibration seat 6. The electric turntable 13 is turned on again to make the measuring cylinder 4 move in a horizontal state until the measuring cylinder 4 reaches above the weighing mechanism 2. The first electric push rod 14 contracts to make the measuring cylinder 4 fall on the weighing mechanism 2. Then, the second electric push rod 16 contracts to drive the transfer fork 17 to retract. At this time, the weighing operation can be carried out. The measuring cylinder 4 can be transferred evenly in a horizontal state, and the dropping rate of resin particles during transfer can be reduced, and the use effect is good.

[0031] The weighing mechanism 2 is set as an electronic scale.

[0032] The vibration mechanism 3 includes a sliding rod 10, a spring 8, a mounting seat 7, a slider 9, a vibration seat 6, and a driving component. A slot matching the measuring cylinder 4 is opened on the vibration seat 6. The bottom of the vibration seat 6 is fixedly connected with a slider 9. The slider 9 is slidably matched on the sliding rod 10. Both ends of the sliding rod 10 are fixedly connected with mounting seats 7.

The eccentric wheel 12 is in contact with the vibration seat 6.

[0034] The transfer mechanism 5 includes an electric turntable 13, a first electric push rod 14, a second electric push rod 16, a connecting block 15, and a transfer fork 17. The electric turntable 13 is installed on the base 1. The top of the electric turntable 13 is fixedly connected with a vertically arranged first electric push rod 14.

The output end of the second electric push rod 16 is fixedly connected with a transfer fork 17. The transfer fork 17 is U-shaped and matches the measuring cylinder 4.

[0035] A protruding ring 26 is fixedly connected to the outer side of the top of the measuring cylinder 4. The protruding ring 26 matches the transfer fork 17. When the transfer fork 17 abuts against the measuring cylinder 4 and rises, the top of the transfer fork 17 will abut against the protruding ring 26, so that when the transfer fork 17 continues to rise, it drives the measuring cylinder 4 to rise.

[0036] It also includes a protective ring for preventing resin particles inside the measuring cylinder 4 from falling during the transfer. The protective ring includes an outer ring 23, a top limiting ring 24, and a bottom limiting ring 25. The top limiting ring 24 is arranged above the protruding ring 26, and the bottom limiting ring 25 is arranged below the protruding ring 26. The top of the outer ring 23 is fixedly connected with the top limiting ring 24, and the bottom of the outer ring 23 is fixedly connected with the bottom limiting ring 25. When the transfer fork 17 abuts against the measuring cylinder 4 and rises, the top of the transfer fork 17 will first abut against the bottom limiting ring 25. Then, as the transfer fork 17 rises, the bottom limiting ring 25 drives the outer ring 23 to rise, making the outer ring 23 higher than the upper edge of the measuring cylinder 4 until the bottom limiting ring 25 abuts against the bottom of the protruding ring 26. When the transfer fork 17 continues to rise, it will drive the measuring cylinder 4 to rise, so that the outer ring 23 will be higher than the mouth of the measuring cylinder 4 during the transfer, ensuring that the resin particles in the measuring cylinder 4 will not fall.

[0037] It also includes an anti-slip component for preventing the measuring cylinder 4 from sliding out of the transfer fork 17 by using the gravity of the measuring cylinder 4. The anti-slip component includes a first airbag 18, a second airbag 19, a connecting pipe 22, a pressing plate 21, and a resilient member 20.

The second airbag 19 is fixedly connected to the inner side of the straight part of the transfer fork 17. A connecting pipe 22 is fixedly connected between the first airbag 18 and the second airbag 19. When the transfer fork 17 transfers the measuring cylinder 4, the weight of the measuring cylinder 4 and the resin particles presses on the pressing plate 21, causing the pressing plate 21 to descend and press the gas in the first airbag 18 into the second airbag 19. The second airbag 19 bulges and clamps the side of the measuring cylinder 4 to prevent the measuring cylinder 4 from slipping out of the straight part of the transfer fork 17.
