Description

Technical Field

[0001] This invention relates to the field of pressing equipment technology, and more particularly to a pressing device. Background Technology

[0002] Sofa leather is the main raw material used to make genuine leather sofas. There are many types of raw materials for sofa leather, including genuine leather, PU leather, PVC shoe upper leather, etc. Generally, in the production of flame-retardant sofa leather, pressing equipment is needed to press the flame-retardant sofa leather to achieve a good production process.

[0003] However, current sofa leather pressing equipment on the market does not have an automatic glue application function. During production, manual glue application is often required before pressing. At this time, it is necessary to control the time well and press as soon as possible after glue application. If the glue application and pressing time is too long, the glue applied in advance will solidify, resulting in the sofa leather not meeting the quality requirements after pressing, poor processing effect, and low product yield.

[0004] Therefore, there is an urgent need for a pressing device to solve the technical problem that existing pressing devices cannot press and apply glue at the same time, resulting in low processing speed and affecting product yield. Summary of the Invention

[0005] The purpose of this invention is to provide a pressing device to solve the technical problem that existing pressing devices cannot perform pressing and gluing simultaneously, resulting in low processing speed and affecting product yield.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] Preferably, the drive structure further includes a motor, a first bevel gear, a second bevel gear, and a round rod. The two ends of the round rod are respectively connected to the motor and the first bevel gear. One end of the lead screw passes through the frame and is connected to the second bevel gear. The first bevel gear and the second bevel gear mesh with each other. When the motor starts, the first bevel gear drives the second bevel gear, thereby causing the lead screw to rotate.

Detailed Implementation

[0024] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0025] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Please see Figure 1 , Figure 2 and Figure 4 As shown, the pressing device in this embodiment includes a base 1, a pad structure 2 fixedly connected to the top of the base 1, a feeding structure installed at one end of the pad structure 2, and a discharging structure installed at the other end of the pad structure 2. A support rod 5 is fixedly connected to the top of the base 1, and a top plate 6 is fixedly connected to the top of the support rod 5. A pressing structure is fixedly installed at the bottom of the top plate 6. The pressing structure is located above the pad structure 2 and matches the pad structure 2. A driving structure is also fixedly connected to the top plate 6. The driving structure matches the pressing structure. A spraying structure is fixedly connected to one side of the driving structure. The bottom of the spraying structure is located between the pressing structure and the pad structure 2. The driving structure is used to press down the pressing structure and drive the spraying structure to move in the horizontal direction. The spraying structure applies glue to the workpiece.

[0027] It should be noted that the feed components of this invention are leather parts and flame-retardant parts. In use, the leather parts and flame-retardant parts are placed on the pad structure 2 through the feeding structure, and then the pressing structure is driven by the driving structure to press them together. When the pressing structure is pressing, the spraying structure moves synchronously with the driving structure, so the spraying pump can be started to apply glue. The glue application and pressing process are coordinated, and the time from glue application to pressing is very short, so the glue will not solidify. The pressing equipment provided by this invention can perform pressing and glue application at the same time, which effectively improves processing efficiency and avoids the technical problem of glue solidification due to premature glue application, which affects the product yield. Of course, it should be emphasized that in practical applications, this pressing equipment can also be used to press other objects, and this invention does not limit it to this.

[0028] Specifically, the pressing structure includes two symmetrical mounting plates 701 and a main pressing block or an auxiliary pressing block. The two symmetrical mounting plates 701 are connected by a connecting rod 10, and the top ends of the two symmetrical mounting plates 701 are fixedly connected to the bottom end of the top plate 6. Multiple main pressing blocks and multiple auxiliary pressing blocks are arranged alternately. The mounting plates 701 are provided with horizontal grooves 702 and multiple vertical sliding grooves 703. The top end of the inner wall of the vertical sliding groove 703 is fixedly connected to a spring telescopic rod 704. The bottom ends of the multiple spring telescopic rods 704 are respectively fixedly connected to the main pressing block or the auxiliary pressing block. The spring telescopic rods 704 constantly provide elastic force for the main pressing block and the auxiliary pressing block to return to the first position.

[0029] For details, please refer to Figure 4 and Figure 5 As shown, the main pressing block includes a main pressing plate 707, a support rod 705, a triangular block 706, and a protrusion 711. The two ends of the support rod 705 are fixedly connected to the main pressing plate 707 and the triangular block 706, respectively. The protrusion 711 is fixedly connected to the support rod 705 and is perpendicular to the support rod 705. The bottom end of the spring telescopic rod 704 is fixedly connected to the protrusion 711.

[0030] Specifically, the auxiliary pressing block includes a limiting block 710, a connecting frame 708, and an auxiliary pressing plate 709. The top of the limiting block 710 abuts against the bottom of the adjacent triangular block 706, and the bottom of the limiting block 710 is connected to the auxiliary pressing plate 709 through the connecting frame 708. The auxiliary pressing plate 709 is located between two adjacent main pressing plates 707, and the bottom of the spring telescopic rod 704 is fixedly connected to the limiting block 710.

[0031] Specifically, the drive structure includes a frame 801, a lead screw 802, a moving block 803, and a hinge block 808. The fixed block of the frame 801 is fixed in the transverse groove 702. The lead screw 802 is rotatably inserted into the frame 801. The moving block 803 is threaded onto the lead screw 802. The bottom end of the moving block 803 is hinged to the hinge block 808. The left side of the moving block 803 is used to abut against the hinge block 808. The right side of the moving block 803 is provided with clearance space for the hinge block 808 to flip.

[0032] For details, please refer to Figure 3 As shown, the drive structure also includes a motor 806, a first bevel gear 804, a second bevel gear 805, and a round rod 807. The two ends of the round rod 807 are connected to the motor 806 and the first bevel gear 804, respectively. One end of the lead screw 802 passes through the frame 801 and the other end is connected to the second bevel gear 805. The first bevel gear 804 and the second bevel gear 805 mesh. When the motor 806 starts, the first bevel gear 804 drives the second bevel gear 805, which in turn causes the lead screw 802 to rotate.

[0033] It should be noted that, in use, the present invention requires the motor 806 to be started. The motor 806 drives the first bevel gear 804, which in turn drives the second bevel gear 805 and the lead screw 802 to rotate, thereby causing the moving block 803 to move along the frame 801. By controlling the direction of rotation of the motor 806, the direction of movement of the moving block 803 can be controlled, allowing the moving block 803 to move from the feeding structure to the discharging structure, or from the discharging structure to the feeding structure. The hinge block 808 deflects to one side of the feeding structure. When the moving block 803 moves from the discharging structure to the feeding structure, the hinge block 808 presses the triangular block 70 of the main pressing block. 6. The main pressing plate 707 of the main pressing block presses the leather part. Since the bottom ends of the limiting block 710 and the triangular block 706 abut against each other, the main pressing plate 707 will drive the adjacent auxiliary pressing plate 709 to press together when it is pressing. When the moving block 803 drives the hinge pressing block 808 to move to the top of another main pressing block, the other main pressing block will still drive the previous auxiliary pressing plate 709 to press together through the main pressing plate 707. That is, the auxiliary pressing plate 709 will press twice, making the overall pressing more flat and the pressing quality higher. After the main pressing block and the auxiliary pressing block are pressed, the spring telescopic rod 704 will reset the corresponding main pressing block and auxiliary pressing block.

[0034] Specifically, the spraying structure includes a spraying frame 901, which passes through a transverse groove 702 and is fixedly connected to a moving block 803. A scraper spray pipe 902 and a spraying pump 903 are fixedly installed between the bottom ends of the spraying frame 901.

[0035] When the movable block 803 of the present invention drives the pressing structure to press through the hinge block 808, the spraying structure moves synchronously with the movable block 803. At this time, the spraying pump 903 can be started to apply glue through the scraper spray pipe 902 and to smooth the glue through the scraper spray pipe 902. Since the spraying structure moves together with the movable block 803 and cooperates with the pressing process of the pressing structure, the time from applying glue to pressing is very short, and the glue will not solidify. The present invention can apply glue while pressing, avoiding the glue solidification caused by applying glue in advance, and also avoiding the situation of bulging during pressing caused by gaps between glues.

[0036] Specifically, the feeding structure also includes a fixed plate 301, a first active roller 302, a first auxiliary roller 303, a second active roller 304, and a second auxiliary roller 305. The fixed plate 301 is fixed on the base 1. The two ends of the first active roller 302, the second active roller 304, the first auxiliary roller 303, and the second auxiliary roller 305 are all located on the fixed plate 301 and can rotate relative to the fixed plate 301. A flame-retardant component is located between the second active roller 304 and the second auxiliary roller 305, and a leather component is located between the first active roller 302 and the first auxiliary roller 303.

[0037] Specifically, the discharge structure includes a discharge roller 4, which is located at the other end of the pad structure 2 and is positioned opposite to the feeding structure.

[0038] In use, the flame-retardant component is fed into the equipment between the second active roller 304 and the second auxiliary roller 305 located below, and the leather component is fed into the equipment between the first active roller 302 and the first auxiliary roller 303 located above. The scraper nozzle 902 is located between the leather component and the flame-retardant component. The motor 806 and the spray pump 903 are started, and the adhesive is applied using the scraper nozzle 902. The motor 806 drives the moving block 803 to move from the discharge structure to the feed structure. During the movement of the hinge block 808, it will abut against the moving block 803 and press down the current main pressing block. The spraying structure and the moving block 803 move together, coordinating with the pressing process of the pressing structure. The time from applying adhesive to pressing is very short, and the adhesive will not solidify. This avoids the problem of adhesive solidification due to pre-application of adhesive and the problem of bulging during pressing due to gaps in the adhesive.
