Description

Technical Field

[0001] This application relates to the field of mortar production technology, and specifically discloses a bagging device for dry powder mortar. Background Technology

[0002] Dry-mix mortar is an industrially produced building material composed of aggregates, cementitious materials, and additives mixed in specific proportions. It features stable quality and convenient construction. The production process of dry-mix mortar includes several main steps: raw material processing, batching, mixing, packaging, and storage. The packaging process primarily involves bagging the mixed dry-mix mortar to facilitate subsequent storage and transportation.

[0003] Currently, the bagging of dry mortar mainly involves feeding the mixed dry mortar into a hopper via a conveyor belt, allowing it to fall into a bag located below the hopper under its own weight. However, this bagging method has the following problems: the weight of each bagged dry mortar is greatly affected by the feeding amount at the conveyor belt's feeding end. When the feeding amount at the conveyor belt's feeding end fluctuates, it will seriously affect the weight accuracy of subsequent baggings, requiring secondary correction of the bagged dry mortar, increasing the complexity of the dry mortar production process. This effect is particularly severe when dry mortar mixed in multiple mixing tanks is transported via the same conveyor belt. In some production lines, metering valves are installed at the bottom of the hopper to accurately control the amount of dry mortar bagged each time. However, since dry mortar is mostly powder and particles, it is easy for it to fall into the gaps of the metering valve and other equipment, increasing the cost of subsequent cleaning, maintenance, and equipment replacement. Therefore, the inventor has provided a dry mortar bagging device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the traditional process of bagging dry powder mortar, when a metering valve is used to control the amount of dry powder mortar bagged each time, the dry powder mortar easily falls into the gaps of the metering valve and other equipment, increasing the cost of subsequent cleaning, maintenance and equipment replacement.

[0005] To achieve the above objectives, the basic solution of this utility model provides a bagging device for dry powder mortar, comprising:

[0006] Support frame;

[0007] The collection hopper is mounted on the support frame. The bottom of the collection hopper is provided with a discharge channel. Several discharge rollers are rotatably and sealed in the discharge channel. Several grooves that can accommodate dry powder mortar falling into the discharge rollers are evenly provided around the periphery.

[0008] A conveyor belt mounted on a support frame and located below the discharge chute;

[0009] A hopper mounted on a support frame and located below the end of the conveyor belt.

[0010] The principle and effect of this basic scheme are as follows:

[0011] Compared with existing technologies, this utility model collects dry mortar mixed in different mixing tanks using a collection hopper. The mortar then falls into the grooves of each discharge roller through a discharge chute, and as the discharge rollers rotate, it falls onto a conveyor belt. The conveyor belt then transports the mortar into a hopper for bagging. The rotation of the discharge rollers controls the weight of the dry mortar falling onto the conveyor belt, ensuring that the weight of each bagged dry mortar is within a set range. This effectively avoids the need for secondary weight adjustments to the bagged dry mortar. It also solves the problem of traditional dry mortar bagging processes where metering valves control the amount of dry mortar bagged each time, leading to mortar easily falling into gaps in the valves and other equipment, increasing the cost of subsequent cleaning, maintenance, and equipment replacement.

[0012] Furthermore, the support frame is symmetrically equipped with baffles located between the bottom sidewall of the discharge trough and the top sidewall of the hopper, and the conveyor belt is slidably connected to the bottom of the baffles. This is to prevent dry mortar from overflowing from both sides of the conveyor belt, thus affecting the weight of the dry mortar bagged each time.

[0013] Furthermore, the support frame is also equipped with a tensioning component that presses the conveyor belt against the bottom of the baffle. This ensures a tighter fit between the conveyor belt and the baffle, preventing gaps between them that could cause dry mortar to overflow.

[0014] Furthermore, the tensioning assembly includes several fixed columns mounted on a support frame, sliding sleeves slidably connected vertically to the fixed columns, top plates respectively mounted on the top of the sliding sleeves and in contact with the conveyor belt, and springs respectively disposed between the sliding sleeves and the support frame. Utilizing the elastic potential energy of the springs, the top plates of the sliding sleeves are pressed tightly against the conveyor belt, thereby ensuring a tight fit between the conveyor belt and the baffle, preventing gaps between the conveyor belt and the baffle that could cause dry mortar to overflow.

[0015] Furthermore, the tensioning assembly includes several fixed sleeves mounted on the support frame, sliding columns slidably connected vertically to each fixed sleeve, top plates respectively mounted on the top of the sliding columns and in contact with the conveyor belt, and springs respectively disposed within the fixed sleeves. Utilizing the elastic potential energy of the springs, the top plates at the top of the sliding columns are pressed against the conveyor belt, thereby ensuring a tight fit between the conveyor belt and the baffle, preventing gaps between the conveyor belt and the baffle that could cause dry mortar to overflow.

[0016] Furthermore, the support frame is also equipped with a scraper that fits against the lower surface of the conveyor belt to promptly scrape off the dry mortar material adhering to the conveyor belt.

[0017] Furthermore, the discharge trough is equipped with several sealing plates, each with an arc-shaped surface on its opposite side that is compatible with the discharge roller. Adjacent sealing plates form a discharge channel that allows the discharge roller to rotate. This facilitates a relatively sealed environment within the discharge trough, allowing the dry mortar to enter the conveyor belt through the grooves on the discharge roller.

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] The reference numerals in the accompanying drawings include: support frame 1, collecting hopper 2, conveyor belt 3, hopper 4, material pipe 5, baffle 6, motor 7, fixed column 8, sliding sleeve 9, top plate 10, spring 11, roller shaft 12, discharge roller 13, sealing plate 14, groove 15.

[0024] A bagging device for dry mortar, implementing, for example Figure 1 As shown: It includes a support frame 1, a collection hopper 2 on the support frame 1, a conveyor belt 3 on the support frame 1 and located below the discharge channel, a hopper 4 on the support frame 1 and located below the end of the conveyor belt 3, and a material pipe 5 located at the bottom of the hopper 4.

[0025] The conveyor belt 3 includes a motor 7 mounted on a support frame 1, pulleys rotatably connected to the support frame 1, a belt tensioned between the pulleys, and a support roller rotatably connected to the support frame 1 that lifts the upper surface of the belt upwards. A scraper is mounted on the support frame 1 to scrape away the dry mortar adhering to the conveyor belt 3 in a timely manner.

[0026] Symmetrical baffles 6 are provided on the support frame 1. The baffles 6 are located between the bottom side wall of the collecting hopper 2 and the top side wall of the hopper 4, and the bottom of the baffles 6 is in contact with the upper surface of the conveyor belt 3. To prevent dry mortar from overflowing from both sides of the conveyor belt 3 and affecting the weight of the dry mortar bagged each time, the support frame 1 is also provided with a tensioning component to press the bottom of the conveyor belt 3 against the baffles 6. Figure 2 As shown, the tensioning assembly includes several fixed columns 8 mounted on the support frame 1, sliding sleeves 9 vertically slidably connected to the fixed columns 8, top plates 10 mounted on the top of the sliding sleeves 9 and in contact with the conveyor belt 3, and springs 11 disposed between the sliding sleeves 9 and the support frame 1. Alternatively, in another embodiment, the tensioning assembly includes several fixed sleeves mounted on the support frame 1, sliding columns vertically slidably connected to the fixed sleeves, top plates 10 mounted on the top of the sliding columns and in contact with the conveyor belt 3, and springs 11 disposed within the fixed sleeves. The elastic potential energy of the springs 11 is used to press the top plates 10 on the top of the sliding sleeves 9 or sliding columns against the conveyor belt 3, thereby ensuring a tight fit between the conveyor belt 3 and the baffle 6, preventing gaps between the conveyor belt 3 and the baffle 6 that could cause dry mortar to overflow.

[0027] like Figure 3 As shown, the bottom of the collection hopper 2 is provided with a discharge channel. Several discharge rollers 13 are rotatably connected in the discharge channel through roller shafts 12. Adjacent roller shafts 12 are rotatably connected through gear pairs. One of the roller shafts 12 is connected to the pulley through belt drive or chain drive. Several sealing plates 14 are provided in the discharge channel. Each sealing plate 14 has an arc-shaped surface that is adapted to the discharge roller 13 on its opposite side. A discharge channel that allows the discharge roller 13 to rotate is formed between adjacent sealing plates 14. Several grooves 15 that allow dry powder mortar to fall into are evenly provided on the periphery of the discharge roller 13. During the rotation of the discharge roller 13, the periphery of the discharge roller 13 is attached to the arc-shaped surface of the sealing plate 14.

[0028] In this embodiment, the power unit drives the conveyor belt 3 and the discharge roller 13 to rotate. The dry mortar mixed in different mixing tanks is collected uniformly through the collection hopper 2 and falls into the grooves 15 of each discharge roller 13 through the discharge channel. As the discharge roller 13 rotates, it falls onto the conveyor belt 3 and is conveyed into the hopper 4 for bagging. The rotation of the discharge roller 13 controls the weight of the dry mortar falling onto the conveyor belt 3, thus ensuring that the weight of the bagged dry mortar is within a set range. This effectively avoids the phenomenon of secondary correction of the weight of the bagged dry mortar. It solves the problem that in the traditional dry mortar bagging process, the dry mortar is easily dropped into the gaps of the metering valve and other equipment, which increases the cost of subsequent cleaning, maintenance and equipment replacement.
