DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0025] See also Figure 1-6 The present invention provides a technical solution: a multi-pass oven, comprising a box 100, a feeding mechanism 200 for a conveyor belt and a silk-screen product to enter the box 100 together, a multi-pass mechanism 300 for performing S-shaped multiple windings on the conveyor belt and the silk-screen product entering the box 100, and a drying mechanism 400 for drying the silk-screen product conveyed by the conveyor belt, wherein the box 100 is composed of a box frame 110 and a box plate 120, the box plate 120 is enclosed on the outside of the box frame 110, the feeding mechanism 200 is arranged at the top of the box 100, the feeding mechanism 200 includes a feeding port 210 at the top of one end of the box 100, and the multi-pass mechanism 300 includes a plurality of full rollers 310 and a plurality of half-hanging rollers 320. The conveyor belt and one end of the silk-screen product successively bypass the plurality of full rollers 310 and the plurality of half-hanging rollers 320 and then flow out from the bottom discharge port 130 at one end of the box body 100. The drying mechanism 400 includes a plurality of heating boxes 410 fixedly connected to the outer side of the box body plate 120 at the back side of the box body 100. A plurality of groups of heating wires 420 are fixedly installed inside each heating box 410. A fan 430 is installed on the top of the heating box 410. The air outlet end of the fan passes through the box body plate 120 and is connected to the inside of the box body 100. The heating box 410 is also connected to the inside of the box body 100 through a plurality of openings 440 provided on the surface of the box body plate 120.

[0026] Specifically, after the silk screen printer has silk-screened the product, the multi-pass oven can be used to dry the product. First, the conveyor belt carrying the silk-screen product enters through the material port 210, and then the feeding mechanism 200 can carry the conveyor belt and the silk-screen product. The multiple full rollers 310 and half hanging rollers 320 provided in the multi-pass mechanism 300 can make the conveyor belt and the silk-screen product bypass in turn, and perform multiple S-shaped windings, so that the travel of the silk-screen product in the box is greatly increased, thereby extending the drying time. Especially for some silk-screen products that have strict drying requirements, the multi-pass mechanism 300 can ensure that the ink is completely cured and improve the adhesion and color stability of the pattern.

[0027] The multiple groups of heating wires 420 inside the multiple heating boxes 410 generate heat after being powered on. The generated heat is blown by the fan 430, enters the box through the opening 440 on the box plate 120, and is evenly distributed around the silk-screened products, thereby comprehensively and continuously drying the products. In addition, the fan 430 can also draw the air inside the box 100 into the heating box 410, and reheat it using the multiple groups of heating wires 420 to form a heat cycle, thereby effectively ensuring the drying efficiency, and then enabling the oven to go from feeding to multi-path transportation to drying, providing an efficient and stable drying environment for silk-screen products, meeting the strict requirements of production for product drying.

[0028] In this embodiment, a plurality of cabinet doors 140 are disposed on the front of the cabinet frame 110 , and each cabinet door 140 is hinged to the cabinet frame 110 via a plurality of hinges 141 .

[0029] Specifically, during routine maintenance and overhaul of the oven, the operator can open the oven door 140 to clean the dust, residual ink particles and other impurities accumulated inside the box body 100, thereby effectively ensuring the service life of the oven;

[0030] During normal daily use of the oven, after opening the oven door 140, the operator can also check whether the heating box 410 is working normally and whether the full roller 310 and the half roller 320 are rotating smoothly, and adjust the equipment parameters in time to ensure that the oven reaches the best working state. Moreover, multiple oven doors 140 can also enable the operator to flexibly choose to open the oven doors 140 of specific areas according to actual needs, without the need for large-scale disassembly of the entire oven, saving maintenance time and labor costs.

[0031] In this embodiment, the feeding mechanism 200 also includes a plurality of first support roller frames 220 installed on the top of the interior of the box frame 110, a feed roller 230 is installed on the top of each first support roller frame 220, a feed guide roller 240 is provided on the side of the feed roller 230 close to the feed port 210, the feed guide roller 240 is installed on the top of the interior of the box frame 110 through a second support roller frame 241, and a feed guide mechanism 250 installed on the outside of the box plate 120 is provided on the outside of the feed port 210, wherein a driving mechanism 260 is installed on one end of two feed rollers 230.

[0032] Specifically, when the silk-screen product is transported to the feed port 210 via the conveyor belt, the feed guide roller 240 first provides preliminary guidance to it, and then the feed roller 230 smoothly delivers the product together with the conveyor belt into the box, and the feed guide mechanism 250 cooperates with the feed roller 230 and the feed guide roller 240 to ensure the accuracy and stability of the feeding process, so that the silk-screen product can smoothly enter the oven for subsequent transportation and drying.

[0033] In this embodiment, the feed guide mechanism 250 includes a first U-shaped frame 251 fixedly mounted on the outside of the box plate 120, a pressure roller 252 at the top of the first U-shaped frame 251 and adjustable in longitudinal height, two guide wheels 253 for limiting the width of the conveyor belt are installed on the surface of the pressure roller 252, and a feed full roller 254 is installed at the bottom of the first U-shaped frame 251.

[0034] Specifically, when the silk-screen products are dried, the pressure roller 252 can be adjusted accordingly according to the thickness of the conveyor belt to ensure that the guide wheel 253 applies appropriate pressure to the conveyor belt and regulates the position of the conveyor belt, thereby ensuring that the conveyor belt can move smoothly. In combination with the feed roller 254, it can prevent it from jumping or deviating during the conveying process, ensuring that the silk-screen products can accurately pass through the feed port 210 into the oven, thereby ensuring the stability of the feeding process.

[0035] In this embodiment, the driving mechanism 260 includes a pulley 261 fixedly connected to the ends of the roller shafts of two full rollers 310, and the pulley 261 is placed outside the box 100. The two pulleys 261 are connected by a belt 262. One of the roller shafts of the full roller 310 is also connected to a first driving motor 263. A tensioning arm 264 is provided at the bottom of the belt 262. One end of the tensioning arm 264 is tensioned by supporting the belt 262 through an installed tensioning wheel 265. The first driving motor 263 and the tensioning arm 264 are fixedly connected to the box frame 110 through a connecting seat 266.

[0036] Specifically, when the feeding mechanism 200 is feeding, the first driving motor 263 can drive the full roller 310 connected thereto to rotate, and through the transmission of the belt 262 and the pulley 261, another full roller 310 is synchronously rotated, so that the full roller 310 has power, thereby realizing stable driving of the conveyor belt;

[0037] The tensioning arm 264 can tighten the belt 262 by adjusting the position of the tensioning wheel 265, ensuring that the belt always maintains an appropriate tension, so that the full roller 310 can stably drive the conveyor belt to operate, providing continuous and stable power for the feeding process, ensuring that the silk-screen products can enter the oven at a uniform and smooth speed, and meeting the requirements of the production process for feeding speed and stability.

[0038] In this embodiment, the width of multiple half-hanging rollers 320 is adapted to the width of the conveyor belt, and the half-hanging rollers 320 and the full rollers 310 are both installed on the inner side of the box frame 110, and the longitudinally distributed half-hanging rollers 320 are positioned opposite to the full rollers 310, and the end of the roller shaft of one of the full rollers 310 away from the feed port 210 is connected to the second drive motor 270, and the second drive motor 270 is also fixedly connected to the box frame 110 through the connecting seat 266.

[0039] Specifically, after the silk-screened product enters the oven with the conveyor belt, it passes through the conveyor belts of the full rollers 310 and the half rollers 320 in sequence, forming an S-shaped path, thereby increasing the residence time of the silk-screened product in the oven, meeting the demand for products with high requirements for drying time, and enabling the product to be more fully exposed to the heat generated by the drying mechanism 400 during the conveying process, thereby improving the uniformity of the drying effect;

[0040] The second driving motor 270 can drive one of the full rollers 310 to rotate, providing continuous power for the multi-path mechanism 300;

[0041] It should be supplemented that the half-roller 320 is adapted to the width of the conveyor belt, which can effectively prevent the conveyor belt from slipping off the full roller 310 during the transmission process, and the half-roller 320 and the full roller 310 can be installed with the box frame 110 in a detachable installation manner. By reasonably adjusting the positions of the half-roller 320 and the full roller 310 and the rotation speed of the second drive motor 270, it can adapt to the drying requirements of different types of silk-screen products and ensure the efficiency and stability of the production process.

[0042] In this embodiment, the outer side of the discharge port 130 is provided with a discharge guide mechanism 150 installed on the outer side of the box plate 120, and the discharge guide mechanism 150 includes a second U-shaped frame 151 fixedly installed on the outer side of the box plate 120, and an active roller 152 is installed at the inner bottom end of the second U-shaped frame 151, and two convex wheels 153 are installed on the outside of the active roller 152, and a third drive motor 154 is installed at one end of the active roller 152, and the third drive motor 154 is fixedly connected to the second U-shaped frame 151, and a driven roller 155 whose longitudinal height can be adjusted is installed at the inner top end of the second U-shaped frame 151, and a guide wheel 156 that is pressed tightly with the convex wheel 153 is installed on the surface of the driven roller 155.

[0043] Specifically, when discharging, the dried silk-screen products arrive at the discharge port 130 along with the conveyor belt, and the guide wheel 156 of the driven roller 155 cooperates closely with the convex wheel 153 to guide and stabilize the conveyor belt. In addition, the driven roller 155 can be adjusted in height according to the thickness of the conveyor belt to ensure that the conveyor belt always maintains stable operation during the discharging process, avoiding problems such as deviation and jamming, and ensuring that the dried silk-screen products can be smoothly and efficiently output from the oven and then enter the subsequent production links.

[0044] In this embodiment, a plurality of adjusting feet 160 are installed at the bottom of the box 100 , and a plurality of rollers 170 are also installed at the bottom of the box 100 .

[0045] Specifically, the adjustment feet 160 can be adjusted according to the ground conditions to keep the oven level. After the adjustment feet 160 are raised, the rollers 170 contact the ground. Using multiple rollers 170 can make the oven easy and convenient to move when it needs to be moved, effectively improving the applicability and practicality of the oven.

[0046] It should be noted that: a temperature sensor is also installed inside the box 100, and the temperature sensor can be used to monitor the temperature inside the box in real time, and then cooperate with the plc controller installed in the control box 500 outside the box 100 to control the heating power of the heating wire 420, so that the box can maintain a suitable drying temperature. At the same time, the plc controller is also electrically connected to the first drive motor 263, the second drive motor 270 and the third drive motor 154 and other actuators. The plc controller can be used to control the speed of the drive motor, so that the conveyor belt carrying the silk-screen products can enter and exit the box 100 at a suitable speed;

[0047] The top of the box body 100 is also connected to a connection pipe 600 for ventilation. The connection pipe 600 can be used to connect an air pump and other devices to achieve ventilation in the box.
