Description

Technical Field

[0001] This utility model relates to the field of mortar sampling technology, and in particular to an automatic mortar bag cutting mechanism. Background Technology

[0002] Mortar is a building material typically composed of cement, sand, water, and additives. It can be used in various construction processes, including masonry, plastering, and floor leveling. Therefore, testing the quality of mortar is crucial to ensuring the safety and reliability of building materials in practical applications. Currently, mortar testing is performed by manually cutting open mortar bags and taking samples of the mortar.

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] In this embodiment, the mortar bag 100 is moved to a designated position above the automatic bag cutting mechanism by an external mechanism, and cooperates with the automatic bag cutting mechanism to perform bag cutting operations. The external mechanism is not limited, but for ease of understanding, the external mechanism in this embodiment is preferably a vacuum suction cup 200. The vacuum suction cup 200 uses negative pressure to adsorb the mortar bag 100 filled with mortar and moves it to the designated position above the automatic bag cutting mechanism, and only then does the automatic bag cutting mechanism start to perform automatic bag cutting operations. The suction force of the vacuum suction cup 200 is 5-10 kg.

[0024] like Figures 1-3 As shown, an automatic mortar bag cutting mechanism includes a mortar feeding trough 1, which is fixedly mounted on a frame 7. A first knife holder mechanism 2 and a second knife holder mechanism 3 are installed on the top of the mortar feeding trough 1. The first knife holder mechanism 2 and the second knife holder mechanism 3 are vertically arranged and can realize the horizontal and vertical openings of the mortar bag 100. A mortar cup 4 is provided at the bottom of the mortar feeding trough 1, and the mortar cup 4 carries the mortar inside the mortar bag 100 after the opening.

[0025] The top of the mortar feeding trough 1 has a ring of outwardly extending mounting parts 11. The mortar feeding trough 1 is fixed to the frame 7 through the mounting parts 11. A shock-absorbing component 5 is provided between the mounting parts 11 and the frame 7. The shock-absorbing component 5 is preferably a shock-absorbing bolt. Several baffles 8 are also provided on the mounting parts 11 to prevent mortar from splashing outward.

[0026] In order to enable the slurry inside the slurry bag 100 to fall quickly into the slurry cup 4 after the opening, a pneumatic vibrator 6 is also fixedly installed on the mounting part 11. The preferred model of the pneumatic vibrator 6 is GT-10.

[0027] Among them, the shock-absorbing component 5 between the mounting part 11 and the frame 7 can reduce the vibration caused by the pneumatic vibrator 6 and prevent the mortar feeding trough 1 from loosening when installed with the frame 7.

[0028] Specifically, the vacuum suction cup 200 adsorbs the sand bag 100 and moves the sand bag 100 to the middle position at the top of the sand feeding trough 1. The first knife holder mechanism 2 and the second knife holder mechanism 3 start to operate, realizing the horizontal and vertical opening of the sand bag 100 from the outside to the inside. Under the action of the pneumatic vibrator 6, the sand in the sand bag 100 can quickly enter the sand cup 4 from the sand feeding trough 1, which is convenient for subsequent sand removal to realize the sand testing.

[0029] This invention uses a first and second cutter holder mechanism to cut bags in a coordinated manner, which is quick and meets the requirements for rapid bag cutting and sand extraction. Compared with manual sand extraction, the force and position are stable, making sand extraction more convenient. It also reduces external interference and improves the accuracy of sand quality testing.

[0030] Further improve the structure of the first knife holder mechanism 2 and the second knife holder mechanism 3 to facilitate understanding of the bag cutting process of the first knife holder mechanism 2 and the second knife holder mechanism 3.

[0031] The first tool holder mechanism 2 is set along the length of the mortar feeding trough 1.

[0032] The first tool holder mechanism 2 includes two sets of first tool holder groups 21 symmetrically arranged and fixed on the top of the mortar feeding trough 1, and a first guide rod 22 connecting the two sets of first tool holder groups 21. The first tool holder group 21 includes a first mounting seat 221 located at one end of the first guide rod 22 and a first fixing seat 222 located in the middle of the first guide rod 22. A first cylinder 223 is arranged between the first mounting seat 221 and the first fixing seat 222. The first cylinder 223 is preferably a magnetically coupled rodless cylinder CY3B15-100-X324. A first tool holder 224 is arranged on the top of the first cylinder 223 and penetrated by the first guide rod 22. The first mounting seat 221 is fixedly arranged on the mounting part 11.

[0033] Since the first cutter holder 224 corresponds to the length direction of the sandbag 100, the first cutter holder 224 cuts the sandbag 100 for a longer length, which can more efficiently obtain the sand inside the sandbag 100. Therefore, the first cutter holder 2241 needs to be equipped with at least two first cutters 2242.

[0034] The first knife holder 224 includes a first knife holder base 2241 and a first knife 2242 fixed on both sides of the front end of the first knife holder base 2241. The first knife 2242 has a sharp top, which improves the efficiency of cutting the bag. The top of the first knife 2242 is higher than the bottom of the sandbag 100.

[0035] Both the first mounting base 221 and the first fixed base 222 are provided with a first proximity switch 225, and the preferred model of the first proximity switch 225 is ex-14a.

[0036] Specifically, the first proximity switch 225 located on the first mounting base 221 can detect that the first tool holder 224 is in the initial position. Then, the symmetrical first cylinder 223 is activated, and the slide on the first cylinder 223 moves from the outside to the inside. The first tool holder 224 fixed on the slide of the first cylinder 223 also moves from the outside to the inside. When the two symmetrical first tool holders 224 reach the designated position, the first proximity switch 225 located on the first fixed base 222 can detect the first tool holder 224. At this time, the sandbag 100 has completed the symmetrical cutting of the bag in the transverse direction. The sandbag 100 after cutting is a waste bag. The vacuum suction cup 200 adsorbs the waste bag and transfers it to the collection box.

[0037] The second cutter holder mechanism 3 is set along the width direction of the mortar feeding trough 1.

[0038] The second tool holder mechanism 3 includes two sets of second tool holder groups 31 symmetrically arranged and fixed to the top of the mortar feeding trough 1, and a second guide rod 32 connecting the two sets of second tool holder groups 31. The height of the second guide rod 32 is lower than that of the first guide rod 22. The second tool holder group 31 includes a second mounting base 321 located at one end of the second guide rod 32 and a second fixing base 322 located in the middle of the second guide rod 32. A second cylinder 323 is arranged between the second mounting base 321 and the second fixing base 322. The second cylinder 323 is preferably a magnetically coupled rodless cylinder CY3B15-100-X324. A second tool holder 324 is arranged on the top of the second cylinder 323 and penetrated by the second guide rod 32. The second mounting base 321 is fixedly arranged on the mounting part 11.

[0039] A second proximity switch 325 is provided on the second mounting base 321 and the second fixing base 322. The preferred model of the second proximity switch 325 is ex-14a.

[0040] The second cutter holder 324 includes a second cutter holder base 3241 and a second cutter 3242 fixed at the middle of the front end of the second cutter holder 324. The second cutter 3242 has a sharp tip, which improves the efficiency of cutting the bag. The tip of the second cutter 3242 is higher than the bottom of the sandbag 100.

[0041] Specifically, the second proximity switch 325 located on the second mounting base 321 can detect that the second tool holder 324 is in the initial position. Then, the symmetrical second cylinder 323 is activated, and the slide on the second cylinder 323 moves from the outside to the inside. The second tool holder 324 fixed on the slide of the second cylinder 323 also moves from the outside to the inside. When the two symmetrical second tool holders 324 reach the designated position, the second proximity switch 325 located on the second fixed base 322 can detect the second tool holder seat 3241. At this time, the sandbag 100 has completed the longitudinal symmetrical cutting of the bag. The sandbag 100 after cutting is a waste bag. The vacuum suction cup 200 adsorbs the waste bag and transfers it to the collection box.

[0042] In this invention, the first knife holder mechanism 2 and the second knife holder mechanism 3 operate simultaneously, which can improve the efficiency of bag cutting and quickly obtain a large amount of adhesive sand.

[0043] However, the first tool holder mechanism 2 and the second tool holder mechanism 3 in this utility model can also operate independently, and when operated independently, they can control the amount of mortar obtained to a specified quality.

[0044] This utility model, through the specific structure of the first cutter holder mechanism 2 and the second cutter holder mechanism 3, can cut the sandbag 100 according to its length and width dimensions, thereby improving the efficiency of bag cutting.
