Description

Technical Field

[0001] This utility model relates to the field of leather pressing technology, and in particular to a multi-layer leather pressing device based on pneumatic clamping. Background Technology

[0002] Leather is a type of animal hide that has undergone physical and chemical processing, possessing properties such as breathability, corrosion resistance, softness, tear resistance, and flexural strength. Pressing typically refers to the process of bonding two or more objects together tightly by applying pressure. After pressing, leather gains increased strength and durability; multiple layers of leather support each other and work together to withstand stress, resulting in greater tensile and tear resistance, and making the product more robust and durable.

[0003] First, prepare the pre-treated leather and place it on the conveyor belt. Then, the leather enters the working platform of the equipment. During cold pressing, pressure is applied directly. During hot pressing, pressure is applied while heating. After applying pressure, the pressure holding stage is maintained for a certain period of time. After the pressure holding is completed, the pressure is slowly reduced. Finally, the pressed leather is taken out and enters the next process.

[0004] However, most existing multi-layer leather pressing equipment relies on operators to manually align the leather during transport. Due to the inherent uncertainties in manual operation, it is difficult for operators to complete the alignment work in a timely and accurate manner, resulting in reduced production efficiency and consequently affecting product quality. Therefore, this art proposes a multi-layer leather pressing equipment based on pneumatic clamping to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-layer leather pressing device based on pneumatic clamping, which aims to improve the problem that most operators manually position the leather, which is prone to errors and difficult to place accurately in the same position, thus affecting the overall quality of the product.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer leather pressing device based on pneumatic clamping, comprising a mounting frame, a motor fixedly connected to the inner side of the mounting frame, a connecting shaft fixedly connected to the output end of the motor, a turntable fixedly connected to the other end of the connecting shaft, two movable parts rotatably connected to the outside of the turntable, a fixed block fixedly connected to the outside of the motor, two sliding rods fixedly connected to the outside of the fixed block, a slider slidably connected to the outside of the sliding rods, a movable block fixedly connected to the top of the slider, a correction plate fixedly connected to the other end of the movable block, a conveyor belt rotatably connected to the inner side of the mounting frame, a motor fixedly connected to the top of the mounting frame, a transmission shaft fixedly connected to the output end of the motor, a synchronous wheel fixedly connected to the outside of the transmission shaft, a compression roller rotatably connected to the top of the mounting frame, a compression roller rotatably connected to the top of the mounting frame, a synchronous wheel fixedly connected to the outside of the compression roller rotatably, and a dust removal device installed on the top of the mounting frame for dust removal from the leather surface.

[0007] Furthermore, the dust removal device includes a connecting pipe, to which a conduit is fixedly connected; a storage box is fixedly connected to the inner side of the mounting frame; a blower is fixedly connected to the top of the storage box; a support frame is fixedly connected to the top of the mounting frame; a cylinder is fixedly connected to the top of the support frame; a push rod is fixedly connected to the output end of the cylinder; a pressure plate is fixedly connected to the bottom end of the push rod; a guide member is fixedly connected to the outside of the push rod; multiple springs are fixedly connected to the bottom of the guide member; a long plate is fixedly connected to the other end of the springs; and two T-shaped pieces are fixedly connected to the top of the long plate.

[0008] Furthermore, the bottom of the turntable is rotatably connected to the top of the fixed block, and the ends of the two movable parts away from the turntable are respectively rotatably connected to the outside of the slider.

[0009] Furthermore, two pointing plates are fixedly connected to the top of the mounting bracket.

[0010] Furthermore, the first synchronous pulley and the second synchronous pulley are connected by a belt.

[0011] Furthermore, the spring is sleeved on the outside of the T-shaped member, and the top end of the T-shaped member passes through the directional member.

[0012] Furthermore, the bottom of the connecting tube is fixedly connected to multiple dust suction ports, and the end of the conduit away from the connecting tube is connected to the interior of the storage box.

[0013] Furthermore, a filter screen is fixedly connected inside the storage box.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, leather is conveyed by a conveyor belt, and then the turntable moves two sliders towards each other through the movable parts. At this time, the sliders drive the movable block and the correction plate to move towards each other at the same time. The correction plate corrects the position of the leather, making the leather position consistent, which facilitates subsequent processing and positioning, and ensures the efficiency of the connection between processes.

[0016] 2. In this utility model, the air inside the storage box is drawn out by a blower to make it into a negative pressure state, and then the dust and impurities on the surface of the leather are sucked out through the dust suction port. At this time, the dust enters the storage box through the duct. By removing dust and impurities, unnecessary wear on the surface of the leather can be reduced, making leather products more durable and extending their normal service life.

[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] Reference Figure 1 , Figure 3 and Figure 5 This utility model provides an embodiment of a multi-layer leather pressing device based on pneumatic clamping, comprising a mounting frame 1, a motor 11 fixedly connected to the inner side of the mounting frame 1, a connecting shaft 12 fixedly connected to the output end of the motor 11, a turntable 13 fixedly connected to the other end of the connecting shaft 12, two movable parts 14 rotatably connected to the outside of the turntable 13, a fixing block 10 fixedly connected to the outside of the motor 11, two sliding rods 7 fixedly connected to the outside of the fixing block 10, a slider 8 slidably connected to the outside of the sliding rods 7, a movable block 9 fixedly connected to the top of the slider 8, a correction plate 3 fixedly connected to the other end of the movable block 9, a conveyor belt 2 rotatably connected to the inner side of the mounting frame 1, and a top of the mounting frame 1... A motor 20 is fixedly connected to the top of the mounting frame 1. A drive shaft is fixedly connected to the output end of the motor 20. A synchronous pulley 21 is fixedly connected to the outside of the drive shaft. A compression roller 15 is rotatably connected to the top of the mounting frame 1. A compression roller 16 is rotatably connected to the top of the mounting frame 1. A synchronous pulley 22 is fixedly connected to the outside of the compression roller 16. A dust removal device is installed on the top of the mounting frame 1 for dust removal from the leather surface. The bottom of the turntable 13 is rotatably connected to the top of the fixed block 10. The ends of the two movable parts 14 away from the turntable 13 are rotatably connected to the outside of the slider 8. Two guide plates are fixedly connected to the top of the mounting frame 1. The synchronous pulley 21 and the synchronous pulley 22 are connected by a belt.

[0027] Furthermore, firstly, motor 11 and motor 20 are started simultaneously, causing turntable 13 and conveyor belt 2 to rotate at the same time. The leather is conveyed via conveyor belt 2. At this time, turntable 13, through movable part 14, drives two sliders 8 to move closer together along the outside of slide bar 7. This, in turn, through movable block 9, drives correcting plates 3 to move closer together. While conveyor belt 2 conveys the leather, the correcting plates 3 correct the leather's position, thus reducing repetitive operation time caused by positional deviations, thereby accelerating the entire production process and increasing output per unit time. Simultaneously, driven by the belt connection... The compression roller 16 and the conveyor belt 2 rotate simultaneously. The leather is squeezed by the cooperation of the compression roller 16 and the compression roller 15. Squeezing helps to improve the elasticity and recovery ability of the leather, reduce deformation, and extend the service life of leather products. The fixed block 10 makes the turntable 13 more stable when rotating. The movable part 14 drives the slider 8 to slide along the outside of the slide bar 7. The guide plate connects the various processes, making the production line smoother and ensuring the efficient operation of the equipment. The belt makes the synchronous pulley 21 and the synchronous pulley 22 rotate simultaneously, further improving the production efficiency of the equipment.

[0028] Reference Figure 2 , Figure 3 and Figure 4 The dust removal device includes a connecting pipe 4, with a conduit 18 fixedly connected to the outside of the connecting pipe 4. A storage box 19 is fixedly connected to the inside of the mounting frame 1. A blower 17 is fixedly connected to the top of the storage box 19. A support frame 5 is fixedly connected to the top of the mounting frame 1. A cylinder 6 is fixedly connected to the top of the support frame 5. A push rod 24 is fixedly connected to the output end of the cylinder 6. A pressure plate 23 is fixedly connected to the bottom end of the push rod 24. A directional component 28 is fixedly connected to the outside of the push rod 24. Multiple springs 26 are fixedly connected to the bottom of the directional component 28. A long plate 27 is fixedly connected to the other end of the spring 26. Two T-shaped components 25 are fixedly connected to the top of the long plate 27.

[0029] Furthermore, the blower 17 is started, and the air inside the storage box 19 is output outward through the blower 17. At this time, the inside of the storage box 19 is in a negative pressure state. Under the action of the negative air pressure, the dust and impurities on the leather surface enter the connecting pipe 4 through the dust suction port, and then are transported through the conduit 18. The dust and impurities enter the inside of the storage box 19. By removing dust and impurities, the appearance of the product made from the leather surface can be more refined and meet higher quality appearance standards. At this time, the leather enters the pressing area under the guidance of the guide plate. At this time, the cylinder 6 is started, so that the push rod 24 drives the pressure plate 23 and the directional part 28 to move downward at the same time. The long plate 27 first contacts the leather surface and clamps and fixes the two sides of the leather. At this time, the spring 26 is in a compressed state, and then the pressure plate 23 presses the multiple layers of leather together, so that the leather adheres to each other and is more secure.

[0030] Reference Figure 1 , Figure 2 and Figure 6 Spring 26 is sleeved on the outside of T-shaped part 25, and the top of T-shaped part 25 passes through directional part 28; multiple dust suction ports are fixedly connected to the bottom of connecting pipe 4, and the end of conduit 18 away from connecting pipe 4 is connected to the inside of storage box 19; a filter screen is fixedly connected to the inside of storage box 19.

[0031] Furthermore, the T-shaped part 25 serves to prevent the spring 26 from deforming and extend its service life; multiple suction ports can effectively reduce the amount of airborne impurities entering the connecting pipe 4, further improving the dust removal efficiency of the leather surface; the filter screen serves to prevent dust and impurities entering the storage box 19 from clogging the blower 17, thereby reducing the dust removal efficiency.

[0032] Working principle: First, motor 11 and motor 20 are started simultaneously, causing turntable 13 and conveyor belt 2 to rotate at the same time. The leather is transported by conveyor belt 2. At this time, turntable 13 drives two sliders 8 to move closer to each other through movable part 14. Simultaneously, sliders 8 drive movable block 9 and correction plate 3 to move closer to each other. The correction plate 3 corrects the position of the leather, allowing the leather to enter the pressing process more smoothly, increasing the flatness of the leather appearance and ensuring the pressing quality. Then, driven by the belt, extrusion roller 2 16 and conveyor belt 2 rotate simultaneously. The leather is squeezed by the cooperation of extrusion roller 2 16 and extrusion roller 15. The squeezing action can fine-tune the leather to a certain extent, making the thickness more uniform and ensuring the consistency of the pressed product.

[0033] Start the blower 17 to draw air out of the storage box 19, creating a negative pressure inside. This allows multiple suction ports to remove dust and impurities from the leather surface. The dust and impurities then enter the connecting pipe 4 and are transported into the storage box 19 by the conduit 18. Removing dust and impurities allows for full and tight contact between the leather pieces, enhancing the bonding effect and making the leather product structure more stable. Guided by the guide plate, the leather is stacked neatly. Start the cylinder 6, causing the push rod 24 to move the pressure plate 23 and the directional component 28 downwards simultaneously. The long plate 27 contacts the leather first and clamps it. At this time, the spring 26 is compressed, and the pressure plate 23 presses the multiple layers of leather together, making the leather pieces fit together.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
