Description

Technical Field

[0001] The utility model relates to the technical field of seat processing, and particularly relates to a seat sponge compression molding machine. Background Art

[0002] A seat sponge compression molding machine compresses and fixes soft sponge materials into the shapes of seat cushions, backrests, etc. through specific mechanical structures and pressure systems to meet the comfort and support requirements of seats. It is widely used in the production processes of automotive seats, furniture sofas, office chairs, etc., and is one of the key equipment indispensable in the manufacturing processes of these products. When processing the sponge into the required shape of the seat in the prior art, during the molding process, a sponge processing mold needs to be used. Since a large amount of heat will be generated inside it, the sponge block can be compressed and shaped. After the processing is completed, manual mold opening is usually required. The residual heat in the mold during mold opening will pose a risk of scalding to the workers. In addition, through the workers' mold opening and mold removal, the series of operations reduce the working efficiency of compressing the sponge into a seat. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a seat sponge compression molding machine, which can effectively solve the problems in the background art.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A seat sponge compression molding machine includes a base table. The upper right part of the base table is fixedly connected with a control keyboard. The front upper end and the rear upper end of the base table are both provided with chutes. The upper end of the base table is fixedly connected with a pulling structure. The upper left part of the base table is fixedly connected with a support frame. The lower part of the inner left wall of the support frame is provided with a card slot, and a sponge cooling structure is clamped in the card slot. The front part and the rear part of the inner upper wall of the support frame are both fixedly connected with a limiting rod, and the ends of the two limiting rods far away from the support frame are jointly fixedly connected with the pulling structure. The upper right part of the support frame is fixedly connected with a sponge compressing device.

[0006] The sponge compressing device includes a first cylinder, which is fixedly connected with the upper end of the support frame. The output end of the first cylinder penetrates through the upper right part of the support frame and is fixedly connected with a compression upper mold. The front middle part and the rear middle part of the compression upper mold are both fixedly connected with ear blocks. The lower end of the compression upper mold is provided with a compression groove, and a cutting knife is fixedly connected to the lower end of the compression upper mold. The compression groove is located inside the cutting knife.

[0007] Preferably, the compression upper mold is respectively inserted and movably connected with the two limiting rods through the two ear blocks.

[0008] By adopting the above technical solutions: The main function of the upper compression mold is to extrude and shape the sponge. The compression groove provides space and shape constraints for the compression of the sponge. The cutting knife is used to cut or trim the sponge during the compression process to achieve the required size and shape. The ear block is movably connected to the limiting rod in an inserted manner, playing a role in guiding and stabilizing the movement of the upper compression mold, ensuring that it moves in a straight line during the up and down movement without deviation or shaking, thereby guaranteeing the accuracy and effect of compression and cutting.

[0009] Preferably, the pulling structure includes a heating table, which is fixedly connected to the upper end of the bottom table. A rectangular opening is formed in the middle of the upper end of the heating table. A cylinder two is fixedly connected to the right end of the heating table. The output end of the cylinder two penetrates through the lower part of the right end of the heating table and is fixedly connected to a lower pressing mold. The lower pressing mold is located within the rectangular opening. A stamping boss is fixedly connected to the middle of the upper end of the lower pressing mold. Long limiting blocks are fixedly connected to both the front and rear lower ends of the stamping boss.

[0010] By adopting the above technical solutions: The rectangular opening provides space and a channel for the movement of the lower pressing mold. The lower pressing mold exerts pressure and pulling force on the sponge through its movement, and cooperates with the stamping boss to stamp and form the sponge. The long limiting blocks limit the movement range of the lower pressing mold, ensuring the accuracy and stability of its movement, and preventing excessive movement or deviation from the predetermined position.

[0011] Preferably, the lower pressing mold is in close contact with the heating table but not fixed. The lower pressing mold is slidably connected to the bottom table through two long limiting blocks and two sliding grooves respectively and is located within the rectangular opening.

[0012] By adopting the above technical solutions: The lower pressing mold slides precisely and stably between the heating table and the bottom table, thereby completing the pulling and stamping processing operations on the sponge.

[0013] Preferably, the lower pressing mold is located directly below the upper compression mold, and the size of the stamping boss is adapted to the size of the compression groove.

[0014] By adopting the above technical solutions: The lower pressing mold being located directly below the upper compression mold ensures that during the processing, the movement and action positions of the two can accurately correspond and work together. The size of the stamping boss is adapted to the size of the compression groove, so that during the compression and stamping operations, the stamping boss can accurately enter the compression groove, realizing the precise forming and processing of the sponge. This adaptability can ensure the accuracy and consistency of the processing, avoid deviations or errors, and thus improve the product quality and production efficiency.

[0015] Preferably, the sponge cooling structure includes a mounting seat. Three heat dissipation fans are fixedly connected to the right end of the mounting seat. A long clamping block is fixedly connected to the lower end of the mounting seat.

[0016] By adopting the above technical solutions: The mounting base, as the basic component for carrying and fixing the cooling fan and the long clamping block, provides support and installation positions for the entire structure. The main function of the cooling fan is to generate airflows, accelerate air circulation, blow air on the sponge seat after being processed and compression-molded, reduce the temperature of the sponge, and help it quickly cool and take shape, thus facilitating the safe removal and feeding by personnel.

[0017] Preferably, the mounting base is in close contact with the inner left wall of the support frame without being fixed. The mounting base is inserted into the support frame through the long clamping block and the clamping groove. All three cooling fans are oriented towards the stamping boss.

[0018] By adopting the above technical solutions: The mounting base being in close contact with the inner left wall of the support frame without being fixed can ensure the position stability of the mounting base. At the same time, not being fixed facilitates installation and disassembly. The insertion fit of the long clamping block and the clamping groove enables the mounting base to be quickly, conveniently and firmly connected to the support frame, ensuring that it will not loosen or fall off during the working process. All three cooling fans are oriented towards the stamping boss, so that the airflows generated by the cooling fans directly blow towards the area where the processed sponge is located, centrally and effectively cooling the sponge, improving the cooling efficiency and effect.

[0019] Compared with the prior art, the present utility model has the following beneficial effects:

[0020] 1. In the present utility model, through the collaborative work of the upper die and the lower die and the rapid drive of the first cylinder and the second cylinder, the sponge block can be quickly compression-molded, greatly shortening the production cycle. The stamping boss and the compression groove are adapted in size, and with the limiting effects of the limiting rod and the long limiting block, the position of the sponge seat during the compression molding process is ensured to be accurate, thus guaranteeing the consistency and high precision of the product. The setting of the cutting knife simultaneously completes the cutting during the compression process, reducing the separate cutting process and improving the processing efficiency.

[0021] 2. In the present utility model, by the simultaneous operation of the three cooling fans, a large amount of air volume can be generated, quickly taking away the heat generated after the sponge seat is compression-molded, accelerating the cooling process, and improving the production efficiency. The cooling fans are all oriented towards the stamping boss, so that the blown air can evenly cover the surface of the sponge seat, achieving relatively uniform cooling, avoiding excessive or too low local temperature, ensuring the stability of the product quality. In addition, quickly reducing the temperature of the sponge seat facilitates the subsequent material taking and handling by the operator, reducing the risk of scalding caused by high temperature and improving the safety of the working environment.

[0030] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0031] A seat sponge compression molding machine includes a base 1. A control keyboard 3 is fixedly connected to the upper right part of the base 1. Chutes 2 are opened at the front upper end and the rear upper end of the base 1. A pulling structure 4 is fixedly connected to the upper end of the base 1. A support frame 6 is fixedly connected to the upper left part of the base 1. A clamping groove 7 is opened at the lower part of the inner left wall of the support frame 6. A sponge cooling structure 8 is clamped in the clamping groove 7. Limiting rods 5 are fixedly connected to the front part of the inner upper wall and the rear part of the inner upper wall of the support frame 6. The two ends of the two limiting rods 5 far away from the support frame 6 are jointly fixedly connected to the pulling structure 4. A sponge compression device 9 is fixedly connected to the upper right part of the upper end of the support frame 6.

[0032] In this embodiment, the sponge compression device 9 includes a first cylinder 91. The first cylinder 91 is fixedly connected to the upper end of the support frame 6. The output end of the first cylinder 91 penetrates through the upper right part of the upper end of the support frame 6 and is fixedly connected to a compression upper die 92. Ear blocks 95 are fixedly connected to the middle of the front end and the middle of the rear end of the compression upper die 92. A compression groove 93 is opened at the lower end of the compression upper die 92. A cutting knife 94 is fixedly connected to the lower end of the compression upper die 92. The compression groove 93 is located inside the cutting knife 94. The compression upper die 92 is respectively inserted and movably connected to the two limiting rods 5 through the two ear blocks 95. The pulling structure 4 includes a heating table 41. The heating table 41 is fixedly connected to the upper end of the base 1. A rectangular opening 42 is opened at the middle of the upper end of the heating table 41. A second cylinder 43 is fixedly connected to the right end of the heating table 41. The output end of the second cylinder 43 penetrates through the lower right part of the right end of the heating table 41 and is fixedly connected to a lower pressing die 44. The lower pressing die 44 is located inside the rectangular opening 42. A stamping boss 46 is fixedly connected to the middle of the upper end of the lower pressing die 44. Long limiting blocks 45 are fixedly connected to the front part of the lower end and the rear part of the lower end of the stamping boss 46. The lower pressing die 44 is in close contact with the heating table 41 but not fixed. The lower pressing die 44 is respectively slidably connected to the base 1 through the two long limiting blocks 45 and the two chutes 2 and is located inside the rectangular opening 42. The lower pressing die 44 is located directly below the compression upper die 92. The size of the stamping boss 46 is adapted to that of the compression groove 93.

[0033] Through the above scheme: First, place the sponge block to be compressed on the stamping boss 46. Start the first cylinder 91 to work. The first cylinder 91 pushes the compression upper die 92 to move downward. The compression upper die 92 can initially cut and trim the sponge block through the cutting knife 94. At the same time, the compression groove 93 compresses the sponge block. Meanwhile, the stamping boss 46 and the compression groove 93 cooperate with each other to further stamp and form the sponge block, making it gradually form the shape of a seat. When the processing is completed, the first cylinder 91 and the second cylinder 43 respectively drive the compression upper die 92 and the lower pressing die 44 to return to the initial position. In addition, since the lower pressing die 44 is in close contact with the heating table 41 but not fixed, and is slidably connected to the base 1 through the long limiting blocks 45 and the chutes 2, its movement is stable and controllable, and it will not cause obstruction or danger to personnel when taking.

[0034] In this embodiment, the sponge cooling structure 8 includes a mounting base 81. Three cooling fans 82 are fixedly connected to the right end of the mounting base 81. A long clamping block 83 is fixedly connected to the lower end of the mounting base 81. The mounting base 81 is in close contact with the inner left wall of the support frame 6 without being fixed. The mounting base 81 is inserted into the support frame 6 through the long clamping block 83 and the clamping groove 7. The three cooling fans 82 all face the direction of the stamping boss 46.

[0035] Through the above solution: After the seat sponge is compression molded, a large amount of heat will be generated due to extrusion and friction during the processing, causing the temperature of the sponge seat to rise. At this time, the three cooling fans 82 start to work. Since they all face the direction of the stamping boss 46, a strong air flow will be generated and directly blown towards the high-temperature seat sponge, accelerating the air flow around the seat sponge and being able to take away the heat on the surface of the sponge, achieving rapid cooling. As the temperature gradually decreases and the temperature of the sponge reaches the safe range, personnel can safely carry out the operation of taking and unloading. In addition, the mounting base 81 is in close contact with the inner left wall of the support frame 6 without being fixed and is inserted through the long clamping block 83 and the clamping groove 7. This connection method not only ensures the stable position of the cooling fans 82 but also facilitates installation and disassembly, making it convenient for maintenance or replacement.

[0036] It should be noted that the present utility model is a seat sponge compression molding machine. During use, first, the sponge block to be processed is placed on the stamping boss 46 of the lower pressing die 44. Then, the cylinder 91 is started to work by controlling the keyboard 3. The output end of the cylinder 91 can push the compression upper die 92 to move downward. The compression upper die 92 can preliminarily cut and trim the sponge through the cutting knife 94. At the same time, the compression groove 93 applies pressure to the sponge for compression. At the same time, the stamping boss 46 and the compression groove 93 cooperate with each other to more precisely stamp and form the sponge, gradually forming the shape of the seat sponge. During this process, the heating table 41 may appropriately heat the sponge to achieve compression molding. After the compression molding is completed, the cylinder 43 drives the lower pressing die 44 to return to the initial position. At this time, the cooling fans 82 start to work and can blow air towards the direction of the stamping boss 46, so as to quickly cool the high-temperature formed seat sponge. After the seat sponge is cooled to an appropriate temperature, personnel can safely take and unload it, enabling the staff to operate safely.
