Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a coating table heating device. Background Technology

[0002] Leather is an indispensable category of consumer goods, widely used in clothing, footwear, home furnishings, automobiles, public services, and many other fields. Among leather products, cowhide products made from genuine cowhide are popular with consumers due to their superior performance and high-end feel, resulting in a large consumption volume.

[0003] The production of artificial leather involves the manufacture of cowhide base fabric. This cowhide base fabric is formed by wet-laying cowhide fibers into a web and then hydroentangling it.

[0004] Flocking is a method of fixing fiber powder (short fibers obtained by grinding or cutting waste fibers) vertically onto an object or substrate coated with adhesive (such as plastic, wood, rubber, leather, paper, cloth, etc.).

[0005] Flocking with adhesive is a surface treatment process that uses an electrostatic field to vertically fix short fiber fluff onto an adhesive substrate. The fluff is negatively charged after electrostatic treatment and moves in a directional manner in a high-voltage electrostatic field, vertically implanting into the surface of the substrate coated with adhesive. Before flocking, adhesive needs to be applied to the surface of the substrate. In the existing adhesive application process, the adhesive on the substrate cools and solidifies, resulting in uneven application, low flocking firmness, and easy fluffing. Utility Model Content

[0006] The purpose of this invention is to overcome the defects in the existing technology and provide a coating platform heating device.

[0007] To achieve the above objectives, the technical solution of this utility model is to design a coating platform heating device, including a frame, the frame having a worktable, a crossbeam spanning the worktable, a rodless cylinder arranged along the length of the crossbeam on the crossbeam, a bracket on the slider of the rodless cylinder, a coating head at the bottom of the bracket, and a heating tube located below the crossbeam near the worktable, the heating tube containing a heating medium, the heating medium entering the heating tube from one end after being heated, and then flowing out from the other end of the heating tube.

[0008] In a further preferred embodiment, the heating tube is detachably installed between the two legs below the crossbeam.

[0009] In a further preferred embodiment, one end of the heating tube is mounted on the support leg by bolts and nuts, and the other end of the heating tube is mounted on the other support leg by bolts and nuts.

[0010] In a further preferred embodiment, the cross-section of the heating tube can be circular, rectangular, or polygonal.

[0011] A further preferred technical solution is that a mold temperature controller is separately installed on one side of the frame. The side of the mold temperature controller is provided with an inlet pipe and an outlet pipe. The inlet pipe is connected to the inlet port of the heating pipe, and the outlet pipe is connected to the outlet port of the heating pipe.

[0012] In a further preferred embodiment, the inlet pipe is connected to the inlet port of the heating tube via a flexible hose, and the outlet pipe is connected to the outlet port of the heating tube via a flexible hose.

[0013] In a further preferred embodiment, temperature sensors are provided at the legs at both ends of the heating tube, and the temperature sensors are electrically connected to the controller of the mold temperature controller.

[0014] The advantages and beneficial effects of this utility model are as follows: the heating tube can heat the glue on the substrate on the worktable, keeping the glue in a molten state and preventing it from solidifying. The glue can be evenly applied to the substrate through the coating table, resulting in uniform application, high flocking firmness, and reduced shedding. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0020] like Figure 1-3 As shown, a coating table heating device is provided. The coating table includes a frame 1, the frame 1 has a worktable 2, and a crossbeam 4 is provided on the worktable 2, the crossbeam 4 being fixed to the worktable 2 by support legs 3 at both ends.

[0021] The crossbeam 4 is equipped with a rodless cylinder 5 arranged along the length of the crossbeam. The rodless cylinder 5 is a special pneumatic actuator that drives the piston to reciprocate by compressed air, but does not require an external piston rod. Instead, it drives the slider to perform linear motion through magnetic coupling or mechanical connection, thereby saving installation space and enabling long-stroke applications.

[0022] The core principle of the rodless cylinder 5 is to use compressed air to drive the piston inside the cylinder to move, and to transmit the power to the external slider through a coupling mechanism (magnetic or mechanical connection) to drive the load to move back and forth. In this embodiment, a mechanical rodless cylinder is preferred.

[0023] The mechanical rodless cylinder 5 includes at least a cylinder barrel, a piston, and a slider; the cylinder barrel has a cylindrical body and an interior space for piston movement.

[0024] The piston is located inside the cylinder and moves back and forth under the influence of compressed air.

[0025] The external load platform of the slider directly drives the actuator.

[0026] The slider is provided with a bracket 6, and the bottom of the bracket 6 is provided with a glue applicator 7. The glue applicator 7 is connected to an external glue supply device through a hose. Specifically, the bracket 6 is connected to the slider through a pair of connecting plates, and the glue applicator 7 can be detachably installed on the connecting plates.

[0027] Both ends of the connecting plate are provided with waist-shaped connecting holes. One end of the connecting plate is connected to the bracket 6 by bolts and nuts, and the other end of the connecting plate is connected to the glue applicator 7 by bolts and nuts. This allows the distance between the glue applicator 7 and the worktable 2 to be adjusted, so that the glue application is uniform and efficient.

[0028] To ensure that the bracket 6 operates stably under the drive of the rodless cylinder 5, a linear guide rail is also provided on the crossbeam 4. The linear guide rail is arranged parallel to the rodless cylinder 5. The bracket 6 has a sliding groove, and the bracket 6 is slidably connected to the linear guide rail through the sliding groove. In this way, the bracket 6 can move stably on the rodless cylinder 5 and the linear guide rail.

[0029] The coating table uses mechanical scraping or spraying to apply adhesive, achieving automatic reciprocating adhesive application, resulting in uniform adhesive layer thickness and improved flocking quality.

[0030] A heating tube 8 is installed below the crossbeam 4 near the worktable 2. The heating tube 8 can heat the glue on the substrate on the worktable 2, keeping the glue in a molten state and preventing it from hardening. The glue can be evenly applied to the substrate through a coating station. Specifically, the heating tube 8 is detachably installed between two support legs 3 below the crossbeam 4. One end of the heating tube 8 is installed on the support leg 3 with a bolt and nut, and the other end of the heating tube 8 is installed on the other support leg 3 with a bolt and nut. Each support leg 3 has a waist-shaped hole arranged vertically, so the height of the heating tube 8 can be adjusted to move it away from or closer to the workpiece on the worktable 2.

[0031] The cross-section of the heating tube 8 can be circular, rectangular, or polygonal. In one embodiment, the cross-section of the heating tube 8 is rectangular, and the rectangular heating tube 8 has a large heating surface covering the substrate.

[0032] The heating medium is a liquid. After being heated, the liquid enters the rectangular heating tube 8 from one end and flows out from the other end. The liquid heats the adhesive through the heating tube 8, preventing the adhesive from curing.

[0033] In order to keep the temperature of the oil stable within a certain range, a mold temperature controller 9 is separately installed on one side of the frame 1.

[0034] Mold temperature controllers (9) are specialized devices used in the industrial field for precise temperature control of molds or equipment. They achieve rapid heating and cooling as well as constant temperature control through the circulation of heat transfer media (water, oil, etc.). Their core functions are to improve product quality, optimize production efficiency, and extend equipment life.

[0035] The mold temperature controller 9 uses a pump to drive the heat transfer medium to circulate between the mold and the heating / cooling system. The temperature sensor monitors the data in real time and feeds it back to the controller, which automatically adjusts the heater or cooling valve to maintain the set temperature. The temperature control accuracy can reach ±0.1℃.

[0036] Water temperature controller: Temperature control accuracy ±1℃, suitable for scenarios below 100℃, environmentally friendly and energy-saving.

[0037] Oil temperature controller: High temperature type can reach 350℃, used for high temperature processes such as rubber vulcanization and chemical reaction kettles.

[0038] In one embodiment, the heat transfer medium of the mold temperature controller 9 is oil. The mold temperature controller 9 is provided with an inlet pipe and an outlet pipe on its side. The inlet pipe is connected to the inlet port of the heating pipe 8 through a hose 10, and the outlet pipe is connected to the outlet port of the heating pipe 8 through a hose 10. The heat transfer medium is driven by a pump to circulate between the heating pipe 8 and the heating / cooling system.

[0039] Temperature sensors are also provided at the support legs 3 at both ends of the heating tube 8. The temperature sensors monitor the data in real time and feed it back to the controller of the mold temperature controller 9, which automatically adjusts the heater or cooling valve to maintain the set temperature.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
