Description

Technical Field

[0001] This utility model belongs to the field of foam technology, specifically relating to a foam filling device. Background Technology

[0002] Foam cotton, also known as foam, is a polymer material with properties such as lightness, softness, elasticity, and sound absorption. Foam cotton is usually made of materials such as polystyrene foam (EPS) or polyurethane (PU). These materials are processed through special processes to form a foam-like material with a porous structure. Foam cotton is a polymer material with many excellent properties and has broad application prospects in packaging, construction, furniture, automobiles, and sporting goods.

[0003] Currently, in today's market environment, foam cotton is widely used to fill the interiors of pipes of various specifications due to its excellent elasticity and resilience, in order to achieve pipe protection and sound insulation. When dealing with pipes with relatively small diameters, directly filling them with foam cotton is quite challenging. A special compression filling rod tool is usually used. When using this compression filling rod, the foam cotton is effectively compressed, allowing it to be smoothly inserted into the pipe. However, when the pipe is long, the elastic recovery ability of the foam cotton will quickly return it to its original state, which may cause the foam cotton to be carried out of the pipe when the filling rod is withdrawn. Utility Model Content

[0004] The purpose of this invention is to provide a foam filling device that can effectively fix the foam inside the pipe, preventing it from being carried out when the pipe is long or under the action of elastic restoring force, thus greatly improving the efficiency and stability of foam filling.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A foam filling device includes a base plate with a groove on its top. A threaded rod is rotatably connected within the groove, and a support plate is slidably connected to the surface of the threaded rod. A first motor is fixedly mounted on one side of the base plate, and the output end of the first motor is fixedly connected to one end of the threaded rod. An extrusion device is mounted on the top of one side of the support plate. Foam is held inside the extrusion device, and a pipe is sleeved on the surface of the extrusion device. A control panel is installed on the side of the support plate away from the extrusion device. A clamping assembly and a fixing assembly are provided on the top of the base plate.

[0007] Preferably, the clamping assembly includes a square plate fixedly connected to the top of the base plate. Two slide rails are fixedly connected to one side of the square plate, and two clamping plates are slidably connected to one side of the two slide rails. A gear is rotatably connected to the side of the square plate near the clamping plates. A rack is meshed with the top and bottom of the gear, and the other end of the rack is fixedly connected to one side of the two clamping plates respectively. A strip-shaped hole is opened on one side of the square plate. A connecting block is fixedly connected to the side of one of the clamping plates near the strip-shaped hole. A second motor is fixedly installed on the side of the square plate away from the slide rails, and the piston rod of the second motor is fixedly connected to one side of the connecting block.

[0008] Preferably, the fixing assembly includes fixing plates fixedly connected to both sides of the top of the base plate, a bidirectional lead screw rotatably connected to one side of the two fixing plates that are close to each other, a third motor fixedly installed on one side of the fixing plate and the output end of the third motor fixedly connected to one end of the bidirectional lead screw, two sliding round rods fixedly connected to one side of the two extrusion devices that are close to each other, a clamping plate slidably connected to the surface of the sliding round rod and the bidirectional lead screw, and a clamping block fixedly installed on the opposite side of the two clamping plates.

[0009] Preferably, each of the clamping blocks has multiple sponge blocks fixedly connected to one side, and the sponge blocks have a square structure.

[0010] Preferably, the support plate has a circular hole, and a push rod that works with the clamping plate is inserted into the circular hole.

[0011] Preferably, two limiting blocks that cooperate with the rack are fixedly installed on the top of one side of the square plate, and the surface of each limiting block is in contact with one side of the rack.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses a foam filling device. By setting up clamping and fixing components, foam is squeezed and fitted onto the surface of a pipe using an extrusion device. A push rod is manually pushed to move one end of the foam a certain distance outside the pipe. Then, a second motor drives a rack to move, which meshes with clamping plates, causing gears to rotate and the two clamping plates to move relative to each other, thus clamping one end of the foam. A third motor, driven by a control panel, rotates a sliding rod, causing the two clamping blocks to move relative to each other and clamp the pipe. When the first motor is driven again to separate the extrusion device from the pipe, the foam inside the extrusion device is efficiently filled into the pipe. This device effectively fixes the foam inside the pipe, preventing it from being carried out by long pipes or elastic restoring forces, greatly improving the efficiency and stability of foam filling.

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figure 1 - Figure 4 As shown, a foam filling device includes a base plate 1, a groove 2 on the top of the base plate 1, a threaded rod 3 rotatably connected in the groove 2, a support plate 4 slidably connected to the surface of the threaded rod 3, a first motor 5 fixedly installed on one side of the base plate 1 and the output end of the first motor 5 fixedly connected to one end of the threaded rod 3, an extrusion device 6 installed on the top of one side of the support plate 4, foam filling is clamped inside the extrusion device 6, a pipe 7 is sleeved on the surface of the extrusion device 6, a control panel is installed on the side of the support plate 4 away from the extrusion device 6, and a clamping assembly and a fixing assembly are provided on the top of the base plate 1.

[0022] The control panel controls the operation of the entire device. The foam cotton is compressed and reduced by the extrusion device 6. Then, the pipe 7 is fitted onto the surface of the extrusion device 6. The control panel on one side of the support plate 4 drives the first motor 5 to rotate the threaded rod 3, so that the support plate 4 can slide in the slide groove 2, thereby conveying the pipe 7 to the fixing component and the clamping component. The fixing component fixes the pipe 7. Then, the clamping component clamps one end of the foam cotton, so that the first motor 5 can drive the extrusion device 6 to take it out of the pipe 7, leaving the foam cotton easily on the inner wall of the pipe 7 and filling the inner wall of the pipe 7.

[0023] like Figure 2 and Figure 3 As shown, the clamping assembly includes a square plate 8 fixedly connected to the top of the base plate 1. Two slide rails 9 are fixedly connected to one side of the square plate 8. Two clamping plates 10 are slidably connected to one side of the two slide rails 9. A gear 11 is rotatably connected to the side of the square plate 8 near the clamping plates 10. A rack 12 is meshed with the top and bottom of the gear 11, and the other end of the rack 12 is fixedly connected to one side of the two clamping plates 10 respectively. A strip hole 13 is opened on one side of the square plate 8. A connecting block 14 is fixedly connected to the side of one clamping plate 10 near the strip hole 13. A second motor 15 is fixedly installed on the side of the square plate 8 away from the slide rails 9, and the piston rod of the second motor 15 is fixedly connected to one side of the connecting block 14.

[0024] Specifically, after the foam cotton is squeezed and fitted onto the surface of the pipe 7 using the extrusion device 6, the push rod 23 is manually pushed to push one end of the foam cotton a certain distance to the outside of the pipe 7. Then, the second motor 15 is driven to move the clamping plate 10. The clamping plate 10 is connected to the second motor 15 through the rack 12, which in turn drives the gear 11 to rotate, causing the two clamping plates 10 to move relative to each other, thereby tightly clamping one end of the foam cotton between the two clamping plates 10. At this time, the first motor 5 is driven to rotate again, causing the extrusion device 6 to be removed from the pipe 7. The foam cotton is clamped by the clamping plate 10, and the foam cotton inside the extrusion device 6 is left on the inner wall of the pipe 7 to fill the pipe 7, so as to efficiently fill the pipe 7 with foam cotton, thereby improving the filling efficiency and filling quality.

[0025] like Figure 2 and Figure 4 As shown, the fixing assembly includes fixing plates 16 fixedly connected to the top two sides of the base plate 1. A bidirectional lead screw 17 is rotatably connected to the side of the two fixing plates 16 that are close to each other. A third motor 18 is fixedly installed on one side of the fixing plate 16, and the output end of the third motor 18 is fixedly connected to one end of the bidirectional lead screw 17. Two sliding round rods 19 are fixedly connected to the side of the two extrusion devices 6 that are close to each other. A clamping plate 20 is slidably connected to the surface of the sliding round rod 19 and the bidirectional lead screw 17. A clamping block 21 is fixedly installed on the opposite side of the two clamping plates 20.

[0026] Two bidirectional lead screws 17 are used to provide auxiliary support for the clamping plates 20, so that the two clamping plates 20 can slide smoothly on the third motor 18. When the pipe 7 moves to the top of the clamping block 21, the third motor 18 is driven by the control panel, which in turn drives the sliding round rod 19 to rotate, so that the two clamping blocks 21 move relative to each other to clamp the pipe 7. When the first motor 5 drives the extrusion device 6 to separate from the pipe 7, the pipe 7 is tightly clamped by the clamping block 21, which prevents the pipe 7 from shaking or shifting, and further improves the accuracy and quality of filling.

[0027] like Figure 4 As shown, each clamp 21 has multiple sponge blocks fixedly connected to one side, and the sponge blocks have a square structure.

[0028] Specifically, the sponge block is used to increase the friction between the sponge and the pipe 7, making the clamping block 21 more stable when clamping the pipe 7, preventing the pipe 7 from sliding or falling off during the filling process. At the same time, the sponge block has a certain degree of elasticity, which can play a buffering role when clamping the pipe 7, preventing damage to the pipe 7 due to excessive clamping force, thereby protecting the integrity of the pipe 7.

[0029] like Figure 1 and Figure 2 As shown, a circular hole 22 is provided on the support plate 4, and a push rod 23 that works with the clamping plate 10 is inserted into the circular hole 22.

[0030] The push rod 23 is used to push the foam cotton in the pipe 7 to the outside of the pipe 7 so that the clamping plate 10 can easily clamp the foam cotton in the pipe 7.

[0031] like Figure 3 As shown, two limiting blocks 24 that cooperate with the rack 12 are fixedly installed on the top of one side of the square plate 8. The surface of each limiting block 24 is in contact with one side of the rack 12.

[0032] Specifically, the limiting block 24 is used to abut against the rack 12 to drive the clamping plate 10 to move horizontally, thereby adjusting the relative position between the clamping plates 10 on both sides and the pipe 7, ensuring that the clamping plate 10 can accurately clamp the foam cotton in the pipe 7; in addition, the design of the limiting block 24 also enhances the stability of the device, making it less likely for the clamping plate 10 to shake when it moves horizontally.

[0033] The working principle of this utility model is as follows: First, the operator places foam cotton into the extrusion device 6 for extrusion and then places it on the surface of the pipe 7. Next, the operator drives the first motor 5 through the control panel to move the support plate 4 on the threaded rod 3 to a suitable distance, and drives the second motor 15 to make the two clamping plates 10 move relative to each other. Then, the operator manually pushes the rod 23 to push the foam cotton in the pipe 7 to the outside of the pipe 7 until the clamping plates 10 hold the foam cotton in the pipe 7. The operator drives the third motor 18 through the control panel to drive the sliding round rod 19 to rotate, so that the two clamping blocks 21 move relative to each other to hold the pipe 7. When the first motor 5 drives the extrusion device 6 to separate from the pipe 7, the foam cotton in the extrusion device 6 remains in the pipe 7 to fill the pipe 7, thus completing the foam cotton filling process.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
