Description

Technical Field

[0001] The invention belongs to a material seamless and traceless pressing device, and relates to a machine that can heat-press and bond materials, and more specifically, to a material hot pressing machine that uses a hot template for pressing and a cold template for shaping. Background Art

[0002] At present, the bonding of clothing fabrics is mainly completed by machine hot pressing and bonding, which greatly shortens the production process. After the product is pressed at high temperature, it needs to be taken out and spread out and placed in a ventilated place for a period of time to achieve the effect of cooling and shaping. However, since the fabrics of clothing, especially underwear, still have elastic shrinkage, and the shrinkage rate of the fabrics is not completely consistent, it is difficult for the product size to reach the uniform size required by the design. In addition, the adhesive is melted after high-temperature pressing, and the natural cooling after releasing the pressing will cause its bonding force to decrease. In order to further improve efficiency and quality, people use cold pressing to cool and shape the fabrics, so that the fabrics can be shaped under the same pressure, ensuring that the products can have unified specifications and quality, which is welcomed by the majority of clothing manufacturers.

[0003] Two patent application documents are given below to reveal the current development status of this type of technology.

[0004] Chinese invention patent application CN106626397A proposes a material bonding machine, which is provided with a hot upper template and a hot lower template, a cold upper template and a cold lower template in the casing. The material is hot pressed by the hot upper template and the hot lower template, and then cooled by the cold upper template and the cold lower template, so that the material can be quickly bonded and shaped.

[0005] Chinese invention patent application CN111113905A discloses a hot pressing machine, which adopts upper and lower working plates that are movably configured with upper and lower bearing frames respectively. The upper and lower working plates can be driven to rise and fall together with the materials by the up and down movement of the lower heating plate and the lower water-cooling plate, and the upper and lower bearing frames can be driven to move forward and backward by the upper and lower driving mechanisms respectively, so that the upper and lower working plates can use the upper and lower heating plates or the upper and lower water-cooling plates together, thereby further improving the efficiency of clothing production.

[0006] In clothing production, some fabrics are not easy to curl and are suitable for processing with the above-mentioned machines; however, some fabrics are easy to curl and form curled edges, which brings great trouble to workers. If these curled edges are not flattened before operation, defective products will easily be produced after hot pressing.

[0007] To this end, some manufacturers have made improvements by fixing a negative pressure mechanism under the work tray that carries the materials, and using the negative pressure generated by the negative pressure mechanism to flatten the fabric in the work tray to solve the problem of fabric curling.

[0008] However, the setting of the negative pressure mechanism increases the space under the working plate. At the same time, the negative pressure will produce air flow. Both will affect the increase in fabric temperature, causing uneven heating of the fabric from top to bottom, and affecting the quality of material bonding. Summary of the invention

[0009] The object of the present invention is to overcome the above-mentioned shortcomings and provide an ironing press machine, which provides a negative pressure mechanism at the feeding station, and adopts the lifting and lowering of the negative pressure mechanism in coordination with the operation of the upper and lower working disks to allow the fabric to be flattened before entering the hot pressing station and / or the cold pressing station, thereby obtaining an ironing press machine that can prevent the edge of the fabric from curling.

[0010] The object of the present invention is achieved in that:

[0011] A hot pressing machine, wherein an upper heating plate and a lower heating plate are arranged at a hot pressing station in a casing, and an upper water-cooling plate and a lower water-cooling plate are arranged at a shaping station, wherein the lower heating plate and the lower water-cooling plate are driven by a power source and can move up and down respectively, two sets of tracks are fixed at both sides of the casing and the two sets of tracks extend to the outside of the front end of the casing, the two sets of tracks are divided into an upper set of tracks and a lower set of tracks, and the upper set of tracks and the lower set of tracks respectively form a feeding station outside the front end of the casing, the upper set of tracks and the lower set of tracks are respectively installed with an upper bearing frame and a lower bearing frame, the upper working disc and the lower working disc are respectively placed in the upper bearing frame and the lower bearing frame, and the upper and lower driving mechanisms are respectively The upper and lower bearing frames are driven, and the upper bearing frame together with the upper working disk, and the lower bearing frame together with the lower working disk can move forward and backward along the upper and lower rails respectively, so that the upper and lower working disks can be located between the upper heating plate and the lower heating plate, or between the upper water-cooling plate and the lower water-cooling plate, or outside the front end of the casing. Its characteristics are that the upper working disk includes an upper chassis and an upper movable cover, the lower working disk includes a lower chassis and a lower movable cover, the upper chassis and the lower chassis are made of temperature-resistant and breathable materials, the negative pressure mechanism is arranged below the feeding and taking station, and the suction disk of the negative pressure mechanism can move up and down and cooperate with the upper and lower working disks respectively, so as to form negative pressure in the upper and lower working disks respectively.

[0012] In this way, when only the lower working disc is left at the feeding and taking position, the suction disc of the negative pressure mechanism can be raised by one gear and cooperate with the lower working disc, and negative pressure can be generated in the lower working disc through the temperature-resistant and breathable material to flatten the fabric, and then the lower movable cover can be closed to clamp the flattened fabric therein so that it can then enter the hot pressing station and the shaping station, and then the suction disc can be lowered back to its original lowest position; when only the upper working disc is left at the feeding and taking position, the suction disc of the negative pressure mechanism can be raised by two gears and cooperate with the upper working disc, and negative pressure can be generated in the upper working disc through the temperature-resistant and breathable material to flatten the fabric, and then the upper movable cover can be closed to clamp the flattened fabric therein so that it can then enter the hot pressing station and the shaping station, and then the suction disc can be lowered back to its original lowest position.

[0013] Therefore, the negative pressure mechanism can utilize the cooperation of the suction plate that rises and falls and the upper and lower working plates that enter the feeding and taking station in turn to generate negative pressure in the upper and lower working plates respectively, so as to flatten the fabrics in the upper and lower working plates.

[0014] In the scheme, the suction plate immediately drops back to its original lowest position after completing the operation, which will facilitate the subsequent upper working plate or lower working plate to enter each work station and will not hinder the operation of the upper working plate or lower working plate.

[0015] In addition, no matter it is the upper working plate or the lower working plate, the material thereon together with the working plate can be sent by the upper and lower driving mechanisms through the upper and lower bearing frames to between the upper heating plate and the lower heating plate, or between the upper water-cooling plate and the lower water-cooling plate, or outside the front end of the casing, and can be hot-pressed by the upper heating plate and the lower heating plate, and shaped by the upper water-cooling plate and the lower water-cooling plate, and finally sent back to the feeding and taking station by the upper and lower driving mechanisms. The upper and lower working plates can complete the operations of feeding, hot pressing, shaping and taking.

[0016] Furthermore, during the hot pressing process, the lower heating plate moves upward to drive the upper working plate or the lower working plate together with its material to rise, so that it leaves the upper carrying frame or the lower carrying frame, and is hot pressed by the upper heating plate and the lower heating plate; during the shaping process, the lower water cooling plate moves upward to drive the upper working plate or the lower working plate together with its material to rise, so that it leaves the upper carrying frame or the lower carrying frame, and is cooled by the upper water cooling plate and the lower water cooling plate.

[0017] In addition, the upper and lower working disks can be driven by the upper and lower driving mechanisms respectively to move forward and backward along the upper and lower rails, and the upper and lower working disks can be placed in the hot pressing station and the shaping station in turn, so that the materials on the upper and lower working disks can be operated in the hot pressing station and the shaping station in turn.

[0018] In the above scheme, the upper driving mechanism may include an upper synchronous motor, an upper synchronous wheel and an upper synchronous belt. The upper synchronous motor drives the upper synchronous belt through the upper synchronous wheel, and the upper synchronous belt drives the upper bearing frame together with the upper working disk to move in the upper group of tracks; the lower driving mechanism may include a lower synchronous motor, a lower synchronous wheel and a lower synchronous belt. The lower synchronous motor drives the lower synchronous belt through the lower synchronous wheel, and the lower synchronous belt drives the lower bearing frame together with the lower working disk to move in the lower group of tracks.

[0019] The use of synchronous motors, synchronous wheels and synchronous belts for driving can make the position of the working disc more accurate during movement or workstation, thereby better ensuring its coordination with the upper and lower heating plates and the upper and lower water cooling plates.

[0020] Preferably, the above scheme also includes a controller, which controls the upper drive mechanism and the lower drive mechanism to make the upper and lower working disks enter the hot pressing station, the shaping station and the feeding station in turn, and the controller controls the operation of the power source and the up and down movement of the suction disk of the negative pressure mechanism to achieve automatic control.

[0021] In the above scheme, an upper working disk sensing switch and a lower working disk sensing switch are provided on the feeding and taking station. The upper working disk sensing switch and the lower working disk sensing switch can respectively obtain in real time the signals of the upper working disk and the lower working disk arriving at or leaving the feeding and taking station. The controller is controlled according to the signals provided by the upper working disk sensing switch and the lower working disk sensing switch, and the position and movement of the upper and lower working disks can be corrected.

[0022] Therefore, by using the cooperation of the upper and lower working plate sensor switches, the movement of the upper and lower working plates and the accuracy of their positions in each station can be guaranteed, preventing the upper and lower working plates from being pressed together at the hot pressing station or the shaping station due to inaccurate positions, which may cause damage to related components.

[0023] In the above scheme, an upper and lower movable cover sensing switch is provided on the feeding and taking station, and the upper and lower movable cover sensing switch can obtain the signal of the upper movable cover or the lower movable cover being opened or closed in real time. The controller is controlled according to the closing signal provided by the upper and lower movable cover sensing switch, allowing the upper working plate or the lower working plate to perform translation operation.

[0024] Therefore, by using the cooperation of the upper and lower movable cover induction switches, it can be ensured that the upper working plate or the lower working plate is moved only after the movable cover is closed, thereby ensuring that the upper and lower working plates will not be misoperated and preventing damage to the machine caused by misoperation.

[0025] Preferably, in the above scheme, an upper and lower movable cover sensing switch is provided on the feeding and taking station, and the upper and lower movable cover sensing switch can obtain the signal of the upper movable cover or the lower movable cover being opened or closed in real time. The controller is controlled according to the opening signal provided by the upper and lower movable cover sensing switch, so that the suction plate of the negative pressure mechanism is executed to rise and the negative pressure mechanism generates negative pressure.

[0026] Therefore, by utilizing the cooperation of the upper and lower movable cover induction switches, it can be ensured that the air suction plate is raised and negative pressure is generated only after the movable cover is opened, so that the opening of the movable cover will not be disturbed and hindered by the negative pressure.

[0027] Preferably, in the above scheme, an upper and lower movable cover sensing switch is provided on the feeding and taking station, and the upper and lower movable cover sensing switch can obtain the signal of the upper movable cover or the lower movable cover being opened or closed in real time. The controller controls according to the closing signal provided by the upper and lower movable cover sensing switch, so that the negative pressure mechanism stops generating negative pressure and the suction plate of the negative pressure mechanism descends.

[0028] Therefore, by using the cooperation of the upper and lower movable cover sensing switches, it can be ensured that the negative pressure mechanism is removed only after the fabric is clamped by the movable cover and the chassis, to ensure that the fabric flattened before clamping is always under the effect of negative pressure, to prevent the negative pressure mechanism from being removed too early and the fabric from curling again.

[0029] Better yet, in the above solution, when the controller detects the opening signal provided by the upper and lower movable cover sensing switches, the controller will further control the rising gear of the suction plate of the negative pressure mechanism according to the signal provided by the upper and lower working plate sensing switches.

[0030] Specifically, in the above scheme, when the upper and lower movable cover sensing switches provide opening signals, when the upper working disk sensing switch is an arrival signal and the lower working disk sensing switch is a departure signal, the controller controls the suction disk of the negative pressure mechanism to rise two gears according to these signals; when the upper and lower movable cover sensing switches provide opening signals, when the lower working disk sensing switch is an arrival signal and the upper working disk sensing switch is a disk departure signal, the controller controls the suction disk of the negative pressure mechanism to rise one gear according to these signals.

[0031] Therefore, under the cooperation of the upper and lower working plate induction switches, the suction plate of the negative pressure mechanism can accurately cooperate with the upper and lower working plates to form negative pressure in the current corresponding working plate.

[0032] Better yet, in the above scheme, when the controller detects the closing signal provided by the upper and lower movable cover sensing switches, the controller will further control the lowering gear of the suction plate of the negative pressure mechanism according to the signal provided by the upper and lower working plate sensing switches.

[0033] Specifically, in the above scheme, when the upper and lower movable cover sensing switches provide a closing signal, when the upper working disk sensing switch is an arrival signal and the lower working disk sensing switch is a departure signal, the controller controls the suction disk of the negative pressure mechanism to drop two gears; when the upper and lower movable cover sensing switches provide a closing signal, when the upper working disk sensing switch is a departure signal and the lower working disk sensing switch is an arrival signal, the controller controls the suction disk of the negative pressure mechanism to drop one gear.

[0034] Therefore, with the further cooperation of the upper and lower working plate induction switches, the suction plate of the negative pressure mechanism can accurately select the descending gear and quickly return to the lowest position to facilitate the subsequent movement of the upper and lower working plates.

[0035] The present invention creates an ironing machine, in which a negative pressure mechanism utilizes the cooperation of an air suction plate that rises and falls and upper and lower working plates that enter the feeding and taking stations in turn, so that negative pressure can be generated in the upper and lower working plates respectively, and the fabrics to be processed located on the upper and lower working plates are flattened to prevent the edges of the fabrics from curling, so that the machine can be adapted to processing fabrics that are prone to curling, thereby improving production efficiency and reducing the labor intensity of workers.

[0036] In the ironing machine of the present invention, the cooperation of the upper and lower movable cover sensing switches can ensure that the opening of the movable cover will not be affected by the negative pressure, and the fabric will always be flattened by the negative pressure before clamping without curling. In particular, the closing of the movable cover can be a prerequisite for continuous operation. When the movable cover is always open, after the operation of the hot pressing station or the shaping station is completed, the lower heating plate and the lower water cooling plate can both be lowered and be in a waiting state until the movable cover is closed to continue working, thereby preventing the machine from being damaged due to misoperation.

[0037] In the ironing machine of the present invention, the upper and lower movable cover sensing switches are further coordinated with the upper and lower working plate sensing switches, and the suction plate of the negative pressure mechanism can be raised and lowered to respectively achieve accurate coordination with the upper and lower working plates, so as to form negative pressure in the corresponding upper working plate or lower working plate to meet the operation of flattening the fabrics in the upper and lower working plates.

[0038] In the ironing machine of the present invention, the upper and lower movable cover induction switches cooperate to make the suction plate of the negative pressure mechanism separate from the working plate in time after the movable cover is closed, so as to ensure that the suction plate does not hinder the movement of the working plate.

[0039] In the hot pressing machine, the suction plate of the negative pressure mechanism can provide negative pressure for the upper and lower working plates that enter the feeding and taking stations in turn by lifting, making it possible for the upper and lower working plates to share a negative pressure mechanism. This solution is conducive to further simplifying the structure and saving the cost of machine manufacturing. BRIEF DESCRIPTION OF THE DRAWINGS

When the processed material is taken out, the material to be processed is put again, and the lower movable cover 10b is closed, the material is clamped by the lower movable cover 10b and the lower chassis 10a. The controller detects that the signal obtained by the upper and lower movable cover induction switch 14 is a closing signal. If the upper working plate induction switch 9c is a leaving signal and the lower working plate induction switch 10c is an arriving signal, the controller controls the negative pressure mechanism to stop generating negative pressure and controls the cylinders 13b and 13c to lower the suction plate 13a by one gear.
