A brick stacking machine for brick product production

Abstract

This utility model relates to a brick stacking machine for brick production, including a support beam mounted on the machine. The support beam has a clamping structure for holding the bricks, comprising two symmetrically distributed grippers. In this brick stacking machine, a lifting component drives an extruder to descend vertically. The trapezoidal pressure plate of the extruder matches the inclined surface of the trapezoidal concave plate of the connecting component, converting the downward driving force into a horizontally opposing clamping force pushing the two grippers along the support beam. Through the cooperation of the inclined surfaces of the trapezoidal pressure plate and the concave plate, the vertical driving force of the cylinder is converted into a horizontal clamping force of the grippers, preventing the push rod from bearing bending stress. The inclined surfaces of the trapezoidal pressure plate and the concave plate decompose the reaction force on the push rod into vertical and horizontal forces on the extruder, thereby reducing the reaction force load on the push rod and delaying metal fatigue caused by prolonged use.

Description

Technical Field

[0001] This utility model relates to the field of brick product manufacturing technology, specifically a brick stacking machine for brick product manufacturing. Background Technology

[0002] Brick products are one of the most widely used basic materials in the construction industry. Their production process varies depending on the type of raw materials and the function of the product. The production process includes raw material preparation, molding, stacking, firing, curing, finished product inspection and delivery. The molding process involves pressing the mixed raw materials into a fixed size, which is mainly divided into two categories: plastic molding and semi-dry pressing. After firing in a tunnel kiln, the bricks are naturally cooled to obtain finished bricks. Then, workers need to use a stacking machine to stack the bricks, with 12-16 bricks per layer and 6-8 layers in total, to facilitate the subsequent curing process.

[0003] In the current technology, the brick stacking machine is used to stack finished bricks by fixing and moving the bricks with clamps. The stacking operation is completed by stacking multiple layers of bricks in both directions until the number of brick layers reaches 6-8.

[0004] In practical use, the gripper controls two clamping plates to move to opposite sides via a cylinder, using the opposing clamping plates to hold the brick, and then moves it up and down. During the clamping phase, the reaction force of the clamping plates on the brick is transmitted to the push rod, causing bending stress in the push rod. During the lifting or moving phase, the superposition of the brick's weight and the inertia force causes the friction between the brick and the clamping plates to be converted into a reaction force on the push rod. After long-term operation, the push rod is prone to deformation due to metal fatigue, thus affecting the service life of the cylinder. Therefore, a brick stacking machine for brick product production is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a brick stacking machine for brick product production. It has the advantage of dispersing the reaction force generated by clamping, solving the problem that during the clamping stage, the reaction force of the clamping plate on the brick is transmitted to the push rod, causing bending stress in the push rod. During the lifting or moving stage, the superposition of the weight of the brick and the inertia of motion causes the friction between the brick and the clamping plate to be converted into a reaction force on the push rod. After long-term operation, this can easily lead to deformation of the push rod due to metal fatigue, thus affecting the service life of the cylinder.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a brick stacking machine for producing brick products, comprising a support beam disposed on the brick stacking machine, wherein the support beam is provided with a clamping structure for clamping bricks;

[0007] The clamping structure includes two symmetrically distributed jaws, which are slidably mounted on a support beam. Each of the two jaws is equipped with a connector. The support beam is provided with two pressing members for pressing the two connectors to opposite sides. The support beam is provided with a lifting component for controlling the up and down movement of the pressing members. The bottom of the support beam is provided with a reset component for resetting the two jaws.

[0008] The connector includes a trapezoidal concave plate mounted on the gripper, and a connecting sleeve for connecting the gripper is fixedly mounted on the bottom of the trapezoidal concave plate, and the connecting sleeve and the connecting sleeve are fixedly connected by bolts.

[0009] The extrusion component includes a horizontal plate, and two symmetrically distributed trapezoidal pressure plates are fixedly installed at the bottom of the horizontal plate, with the inclined surface of the trapezoidal pressure plate matching the groove of the trapezoidal concave plate.

[0010] The lifting component includes a mounting frame fixedly installed on a support beam, and two cylinders are fixedly installed on the mounting frame, with the telescopic ends of the cylinders fixedly connected to the horizontal plate.

[0011] Furthermore, the reset component includes a guide rod and two springs, with the guide rod fixedly installed at the bottom of the support beam, and the two springs respectively sleeved on the guide rod and symmetrically distributed, with the two springs located between the two grippers.

[0012] Furthermore, a reinforcing rib is fixedly installed on the top of the horizontal plate.

[0013] Furthermore, two limiting rods are fixedly installed on the mounting bracket, with one end of each limiting rod penetrating through the horizontal plate, and the horizontal plate and the limiting rods are slidably connected.

[0014] Furthermore, the connecting sleeve is provided with four symmetrically distributed pins, one end of which passes through the connecting sleeve and extends to the gripper.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. This brick stacking machine for brick production has a support beam that provides the installation foundation for the overall structure, a clamping structure that is responsible for clamping the bricks, and a lifting component that drives the extruder to descend vertically. The trapezoidal pressure plate of the extruder and the trapezoidal concave plate of the connecting component are adapted to each other, converting the vertical downward driving force into a clamping force that pushes the two grippers horizontally towards each other along the support beam. Through the cooperation of the trapezoidal pressure plate and the trapezoidal concave plate, the vertical driving force of the cylinder is converted into the horizontal clamping force of the grippers, avoiding the push rod from bearing bending stress.

[0017] 2. This brick stacking machine for brick production utilizes the inclined surfaces of a trapezoidal pressure plate and a trapezoidal concave plate to decompose the reaction force on the push rod into vertical and horizontal forces on the extruded parts through these inclined surfaces, thereby reducing the reaction force load on the push rod and delaying metal fatigue caused by long-term use of the push rod.

[0018] 3. This brick stacking machine for brick production uses a guide rod to limit the sliding trajectory of the grippers, preventing gripper deviation and ensuring consistent gripper position after each reset, thus improving stacking accuracy. Two symmetrically distributed springs provide balanced reset force, preventing jamming caused by unilateral force on the grippers. The springs utilize elastic potential energy to achieve automatic gripper reset without the need for additional power. Attached Figure Description

Detailed Implementation

[0025] 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.

[0026] Example 1: Please refer to Figure 1-5 In this embodiment, a brick stacking machine for producing brick products includes a support beam 1 mounted on the brick stacking machine, and a clamping structure 2 for clamping bricks is mounted on the support beam 1.

[0027] Example 2: Please refer to Figure 1-5 Based on Embodiment 1, the clamping structure 2 includes two symmetrically distributed grippers 21, and the grippers 21 are slidably mounted on the support beam 1. Each gripper 21 is equipped with a connector 22. The support beam 1 is provided with two pressing members 23 for pressing the two connectors 22 to the opposite side. The support beam 1 is provided with a lifting member 24 for controlling the up and down movement of the pressing members 23. The bottom of the support beam 1 is provided with a reset member 25 for resetting the two grippers 21.

[0028] The connector 22 includes a trapezoidal concave plate 221 mounted on the gripper 21. A connecting sleeve 222 for connecting the gripper 21 is fixedly mounted on the bottom of the trapezoidal concave plate 221, and the connecting sleeve 222 is fixedly connected to the gripper 21 by bolts.

[0029] The extrusion part 23 includes a horizontal plate 231, and two trapezoidal pressure plates 232 that are symmetrically distributed are fixedly installed at the bottom of the horizontal plate 231, and the inclined surface of the trapezoidal pressure plate 232 is adapted to the groove of the trapezoidal concave plate 221.

[0030] The lifting component 24 includes a mounting frame 241 fixedly installed on the support beam 1, and two cylinders 242 are fixedly installed on the mounting frame 241, and the telescopic ends of the cylinders 242 are fixedly connected to the horizontal plate 231.

[0031] Among them, the top of the horizontal plate 231 is fixedly installed with a reinforcing rib 233. The reinforcing rib 233 enhances the bending strength and rigidity of the horizontal plate 231, prevents the horizontal plate 231 from deforming, ensures the relative position stability of the horizontal plate 231 and the trapezoidal pressure plate 232, ensures the accuracy of the force conversion of the trapezoidal structure, and ensures the continuous and reliable clamping force.

[0032] In addition, two limiting rods 243 are fixedly installed on the mounting bracket 241. One end of each limiting rod 243 passes through the horizontal plate 231, and the horizontal plate 231 is slidably connected to the limiting rods 243. The limiting rods 243 restrict the lifting trajectory of the horizontal plate 231, allowing it to move only in the vertical direction, avoiding deviation or tilting, ensuring that the trapezoidal pressure plate 232 and the inclined surface of the trapezoidal concave plate 221 are accurately fitted, the force conversion efficiency is stable, and the wear of components is reduced.

[0033] It should be noted that the connecting sleeve 222 is provided with four symmetrically distributed pins, and one end of the pins passes through the connecting sleeve 222 and extends to the clamp 21. The pins can share the horizontal force borne by the bolt, prevent the bolt from loosening or breaking, and improve the overall stability of the clamping structure 2.

[0034] Using the above technical solution, the cylinder 242 of the lifting component 24 retracts, and its telescopic end drives the horizontal plate 231 to descend vertically along the limiting rod 243. The limiting rod 243 ensures that the horizontal plate 231 does not deviate. The horizontal plate 231 drives the two trapezoidal pressure plates 232 at the bottom to descend synchronously. The inclined surface of the trapezoidal pressure plate 232 gradually embeds into the groove of the trapezoidal concave plate 221. As the cylinder 242 continues to shorten, the trapezoidal pressure plate 232 generates a vertically downward squeezing force on the inclined surface of the trapezoidal concave plate 221. This force is decomposed into a horizontal component along the inclined surface. The horizontal component pushes the two connecting pieces 22 and the clamping claws 21 fixed thereto to slide horizontally towards each other along the support beam 1. At the same time, it compresses the two springs 252 of the reset component 25 until the clamping claws 21 are in close contact with the brick surface, thus completing the brick clamping.

[0035] Example 3: Please refer to Figure 1-5 Based on Embodiment 2, the reset component 25 includes a guide rod 251 and two springs 252. The guide rod 251 is fixedly installed at the bottom of the support beam 1, and the two springs 252 are respectively sleeved on the guide rod 251 and are symmetrically distributed. The two springs 252 are located between the two grippers 21.

[0036] In addition, the guide rod 251 restricts the sliding trajectory of the gripper 21 to prevent the gripper 21 from deviating, ensuring that the position of the gripper 21 is consistent after each reset, thus improving the stacking accuracy. The two symmetrically distributed springs 252 can provide a balanced reset force to prevent the gripper 21 from jamming due to force on one side.

[0037] Using the above technical solution, when the bricks reach the stacking position, the cylinder 242 extends, driving the horizontal plate 231 and the trapezoidal pressure plate 232 to rise vertically. The trapezoidal pressure plate 232 separates from the trapezoidal concave plate 221, the horizontal squeezing force disappears, the spring 252 of the reset component 25 releases elastic potential energy, and pushes the two grippers 21 to slide horizontally in the opposite direction along the guide rod 251, restoring to the initial maximum spacing, and the bricks naturally fall into the stacking position.

[0038] The working principle of the above embodiments is as follows:

[0039] When the brick stacking machine for brick production is in use, the cylinder 242 of the lifting component 24 is in the extended state, which drives the horizontal plate 231 and trapezoidal pressure plate 232 of the extrusion component 23 to a high position. The trapezoidal pressure plate 232 is not in contact with the trapezoidal concave plate 221 of the connecting component 22. The two springs 252 of the reset component 25 are in the naturally extended state, and the guide rod 251 restricts the position of the gripper 21, so that the two grippers 21 maintain the maximum distance and wait for the brick to enter the clamping area.

[0040] When the brick is conveyed between the two grippers 21, the cylinder 242 of the lifting component 24 retracts, and its extension end drives the horizontal plate 231 to descend vertically along the limit rod 243. The limit rod 243 ensures that the horizontal plate 231 does not deviate. The horizontal plate 231 drives the two trapezoidal pressure plates 232 at the bottom to descend synchronously. The inclined surface of the trapezoidal pressure plate 232 gradually embeds into the groove of the trapezoidal concave plate 221.

[0041] As the cylinder 242 continues to shorten, the trapezoidal pressure plate 232 exerts a vertically downward squeezing force on the inclined surface of the trapezoidal concave plate 221. This force is decomposed into a horizontal component along the inclined surface. The horizontal component pushes the two connecting pieces 22 and the clamping claws 21 fixed thereto to slide horizontally towards each other along the support beam 1, while simultaneously compressing the two springs 252 of the reset component 25.

[0042] Until the gripper 21 makes tight contact with the surface of the brick, generating a stable clamping force, the brick clamping is completed;

[0043] When the bricks reach the stacking position, the cylinder 242 extends, causing the horizontal plate 231 and the trapezoidal pressure plate 232 to rise vertically. The trapezoidal pressure plate 232 separates from the trapezoidal concave plate 221, the horizontal squeezing force disappears, the spring 252 of the reset component 25 releases elastic potential energy, and pushes the two grippers 21 to slide horizontally in the opposite direction along the guide rod 251, restoring to the initial maximum spacing, and the bricks naturally fall into the stacking position.
