Description

Technical Field

[0001] The present invention belongs to the technical field of automated equipment and relates to a method for producing lead weights. Background Art

[0002] A lead weight is an essential auxiliary fishing tackle in a fishing set. When casting a fishing rod for long-distance casting, the angler relies on its weight to cast the hook bait into the fishing spot in front. After entering the water, it also acts by its weight to balance the fishing set; when a fish bites the hook, the fishing hook can use the weight of the lead weight to pierce the fish's lip and hook the fish.

[0003] Currently, the production of lead weights is either done by manual rolling or by using an automatic lead winding machine. Although the above methods can meet the production requirements, there are still many deficiencies. Using the manual rolling method, it is inevitable to come into contact with lead strips for a long time. If the production workers have insufficient protection awareness, it will inevitably affect their health. In addition, the manual rolling method is only suitable for small-batch production and has low production efficiency. The existing automatic lead winding machines have, to a certain extent, met the need for automated production of lead weights, but the current machine stability is still insufficient, and the defect rate of finished products is high. Currently, manual selection and sorting are required. In addition, the equipment for the post-treatment process (heating - cooling - dehydration - polishing - separation) of current lead weight production is relatively independent and not interconnected in series. Manual handling of lead weights one by one is laborious and often involves contact with lead, and the production environment is relatively unfriendly. Summary of the Invention

[0004] The present invention aims to overcome the deficiencies of the prior art and provides a method for producing lead weights.

[0005] To achieve the above object, the present invention adopts the following technical solutions: A method for producing lead weights, which is based on a lead weight production device for lead weight production, including the following steps:

[0006] Step 1: The lead winding machine winds lead.

[0007] Step 2: The front vibrating plate preliminarily screens semi-finished lead weights.

[0008] The lead winding machine transports the semi-finished lead weights to the front vibrating plate through the feeding conveyor line. The width of the guiding groove of the front vibrating plate matches the width of the lead weight. If the semi-finished lead weights with good appearance that meet the settings of the guiding groove pass through the guiding groove and the steps are executed; otherwise, the defective lead weights are collected in the defective area.

[0009] Step 3: The sorting device screens semi-finished lead weights.

[0010] Step 4: The main controller controls the drying chamber at the target temperature, and the drying tunnel device heats the conduit of the lead weight.

[0011] Step 5: The winding device cools the conduit of the semi-finished lead sinker through normal temperature or cooling water, and then winds it up.

[0012] Step 6: The drying device dries the moisture of the wound lead sinker.

[0013] Step 7: The dried lead sinker is transported to the storage device, which then transports the lead sinker to the polishing box. The polishing and separation device polishes the lead sinker. After polishing, the polished wooden board and the finished lead sinker are separated through the separation box. The polished wooden board is collected in the wooden board collection box, and the manipulator transfers the polished wooden board to the polishing box.

[0014] Step 8: The finished lead sinker falls into the vibrating disk. After being counted by the counting sensor, the finished lead sinker falls into the finished product collection box for collection.

[0015] Further, the method for winding lead by the lead winding machine 1 in the above Step 1 includes the following steps:

[0016] Step 1.1: The lead feeding device of the lead winding machine transports the lead bar to the second set position.

[0017] Step 1.2: The pressing and cutting device of the lead winding machine presses and cuts the lead bar. The head end of the lead bar to be wound is located on the plane of the folding plate of the lead winding machine, and the lead bar to be wound except the head end is located on the lead winding table of the lead winding machine.

[0018] Step 1.3: The guide pin device and the feeding device of the lead winding machine operate to transport the conduit above the lead bar to be wound.

[0019] Step 1.4: The lead folding mechanism of the lead winding machine is started to pre-fold the head end of the lead bar to be wound in Step... on the conduit. The forming mechanism presses and wraps the lead bar to be wound around the conduit to make the formed lead sinker. The pipe cutting device of the lead winding machine is started to cut the conduit and reset. The guide pin device and the feeding device are reset. The lead winding mechanism of the lead winding machine rolls the formed lead sinker to automatically wind the lead and make the semi-finished lead sinker.

[0020] Step 1.5: The semi-finished lead sinker falls into the discharge plate for discharging.

[0021] Further, the method for screening semi-finished lead sinkers by the sorting device in the above Step 3 includes the following steps:

[0022] Step 3.1: The vision camera of the sorting device collects the image of the screening vision area.

[0023] Step 3.2: Determine whether the semi-finished lead sinker enters the screening vision area. If yes, execute Step 3.3; if not, execute Step 3.1.

[0024] Step 3.3: Determine whether there are shape defects in the semi-finished lead sinker. If so, the semi-finished lead sinker is judged as a defective product, and step 3.4 is executed. If not, the semi-finished lead sinker is judged as a high-quality product, and the high-quality product is transported to the drying tunnel device, and step 4 is executed to complete one screening, and then step 3.1 is executed to repeat the screening process of the semi-finished lead sinker;

[0025] Step 3.4: Eliminate the defective products. The main controller controls the sorting mechanism of the sorting device to start, so that the defective products fall into the defective product collection device.

[0026] Further, the method for determining whether the semi-finished lead sinker enters the screening vision area in step 3.2 includes the following steps:

[0027] Step 3.2.1: Set the area threshold S0 of the standard semi-finished lead sinker occupying the pixels of the vision camera's field of view;

[0028] Step 3.2.2: The vision camera collects the image P1 of the screening vision area, and the grayscale image P2 is obtained by graying P1;

[0029] Step 3.2.3: Retrieve the area S1 with the gray value > G1 according to the threshold segmentation of the grayscale image P2;

[0030] Step 3.2.4: Judge whether S1 is greater than S0. If so, execute step 3.2.5. If not, it is determined that the semi-finished lead sinker has not entered the screening vision area, and step 3.2.2 is executed;

[0031] Step 3.2.5: Judge whether there is a lead sinker at the boundary of P2.

[0032] Further, the method for determining whether there is a lead sinker at the boundary of P2 in step 3.2.5 is as follows: If the gray value of the boundary of P2 > G1, it is determined that there is a lead sinker at the boundary of P2, indicating that the lead sinker has not completely entered the screening vision area, and step 3.2.2 is executed. If the gray value of the boundary of P2 < G1, it is determined that there is no lead sinker at the boundary of P2, indicating that the lead sinker has completely entered the screening vision area, and the defects of the lead sinker in P1 are identified, and then step 3.3 is executed.

[0033] Further, the lead sinker production device includes a lead coiling machine, a feeding conveyor line, a front vibrating tray, a sorting device, a drying tunnel device, a winding device, a drying device, a storage device, a polishing and separation device, a finished product collection device and a control system arranged in sequence. The control system includes a main controller, and the lead coiling machine, the feeding conveyor line, the front vibrating tray, the sorting device, the drying tunnel device, the winding device, the drying device, the storage device, the polishing and separation device, and the finished product collection device are respectively connected to the main controller.

[0034] Further, the sorting device is located between the front vibrating tray and the drying tunnel device, and the sorting device is respectively docked with the front vibrating tray and the drying tunnel device.

[0035] Further, the sorting mechanism includes a sorting motor, a sorting block, and a sorting plate. The output shaft of the sorting motor is fixedly provided with the sorting block, the length of the sorting block is greater than the length of the semi-finished lead weight, the sorting plate is connected to the sorting machine frame, the sorting plate is inclined, and the main controller is communicatively connected to the sorting motor.

[0036] Further, the target temperature value of the drying tunnel device is greater than the temperature value of the drying device.

[0037] Further, the second set position is located in the plane of the folding plate.

[0038] In summary, the advantages of the present invention are as follows:

[0039] 1) The present invention combines a lead coiling machine, a sorting device, a drying tunnel device, a winding device, a drying device, a storage device, a polishing and separation device, and a finished product collection device and connects them in series with each other, realizing the automated process of lead weight from coiling, sorting, heating, cooling, dehydration, polishing, separation, and finished product collection, reducing the manual intervention in each process and the manual ratio of the entire production line, reducing the physical consumption in the handling link, improving the production efficiency of lead weights, realizing the mass production of lead weights, reducing the defective rate caused by manual intervention, and at the same time automatically controlling each process through the control system, precisely and standardizing the operation processes of each process, effectively improving the qualified rate.

[0040] 2) The present invention preliminarily eliminates defective lead weights through the guiding grooves of the front vibrating disk, transports the lead weights with acceptable shapes to the sorting device through the guiding grooves for preliminary sorting. At the same time, the present invention realizes a detection algorithm through the sorting device, recognizes the images in the screening visual field area collected by the vision camera and the shapes of the lead weights in the images through the detection algorithm, and feeds the recognition results back to the main controller. The main controller further screens by comparing and judging whether the shape of the current lead weight is qualified, thus realizing the automatic and precise screening of the shapes of lead weights.

[0041] 3) The present invention divides the upper drying tunnel into a front chamber, a middle chamber, and a rear chamber, and controls the temperature of the front chamber, the middle chamber, and the rear chamber separately. The main controller controls the temperature at each position in the drying chamber at a relatively stable temperature value to improve the heating uniformity of the ducts of the semi-finished lead weights and reduce the defective rate of the lead weights.

[0076] The lead bar device 10 includes a lead bar reel 101, a lead bar guide frame 103, a lead bar support frame 104, and a mechanism fixing frame 105. A lead bar 102 is wound around the lead bar reel 101. The lead bar guide frame 103 and the lead bar support frame 104 are fixedly arranged on the mechanism fixing frame 105. The mechanism fixing frame 105 is fixedly arranged on the lead winding machine platform 13. The lead bar guide frame 103 is located between the lead bar support frame 104 and the lead bar reel 101. After being guided by the lead bar guide frame 103 and supported by the lead bar support frame 104, the lead bar 102 extends to the lead feeding device 11.

[0077] The lead feeding device 11 includes a front lead feeding mechanism, a rear lead feeding mechanism, and a bottom plate mechanism. The front lead feeding mechanism includes a front feeding motor 110, a front feeding cylinder 111, and a front feeding plate 112. The front feeding motor 110 and the front feeding cylinder 111 are fixedly arranged on the front feeding plate 112. The front feeding plate 112 is slidably connected to the bottom plate mechanism. Specifically, the bottom plate mechanism includes a bottom plate 119, a bottom slider 1191, and a bottom slide rail 1192. The bottom plate 119 is fixedly arranged on the lead winding machine platform 13. The bottom slide rail 1192 is fixedly arranged on the bottom plate 119. Preferably, two groups of bottom slide rails 1192 are provided. The length direction of the bottom slide rail 1192 is consistent with the moving direction of the lead bar 102. The bottom slider 1191 is movably arranged on the bottom slide rail 1192. The front feeding plate 112 is fixedly connected to the bottom slider 1191. Through the above structure, the front feeding plate 112 is slidably connected to the bottom plate mechanism.

[0078] The front feeding plate 112 is fixedly provided with a concave front feeding groove 1120. The lead bar 102 is located in the front feeding groove 1120. The output end of the front feeding cylinder 111 is fixedly provided with a front pressing plate 1110. The front pressing plate 1110 is located above the front feeding groove 1120. When the front feeding cylinder 111 is activated to move the front pressing plate 1110 downward, the lead bar 102 is pressed against the front feeding plate 112 by the front pressing plate 1110, realizing the movement of the lead bar 102.

[0079] The front feeding motor 110 is used to drive the front lead feeding mechanism to move. Specifically, the front feeding motor 110 is fixedly arranged on the front feeding plate 112. The output shaft of the front feeding motor 110 is fixedly provided with a front feeding main gear 1171. The bottom plate 119 is fixedly provided with a front feeding rack 1172. The front feeding main gear 1171 is meshed and connected with the front feeding rack 1172. When the front feeding motor 110 is activated, the front feeding plate 112 is driven to slide along the bottom plate mechanism through the meshing action of the front feeding main gear 1171 and the front feeding rack 1172.

[0080] The rear lead feeding mechanism includes a rear feeding motor 113, a rear feeding cylinder 114 and a rear feeding plate 115. The rear feeding motor 113 and the rear feeding cylinder 114 are fixedly arranged on the rear feeding plate 115. The rear feeding plate 115 is fixedly connected with the bottom slider 1191, realizing the sliding connection between the rear feeding plate 115 and the bottom plate mechanism through the above structure.

[0081] The rear feeding plate 115 is fixedly provided with a concave rear feeding groove 1150. The lead bar 102 is located in the rear feeding groove 1150. The front feeding groove 1120 and the rear feeding groove 1150 are opposite and collinear. The output end of the rear feeding cylinder 114 is fixedly provided with a rear pressing plate 1140. The rear pressing plate 1140 is located above the rear feeding groove 1150. When the rear feeding cylinder 114 is activated to move the rear pressing plate 1140 downward, the lead bar 102 is pressed against the rear feeding plate 115 by the rear pressing plate 1140, realizing the movement of the lead bar 102.

[0082] A lead feeding linkage mechanism is also provided between the front lead feeding mechanism and the rear lead feeding mechanism. The linkage of the front lead feeding mechanism and the rear lead feeding mechanism is realized through the lead feeding linkage mechanism. Specifically, the lead feeding linkage mechanism includes a lead feeding connecting rod 1161, a lead feeding long rod 1162, and a linkage fixing bracket 1163. The lead feeding connecting rod 1161 includes a fixed end and a movable end. The fixed end is fixedly connected to the output shaft of the rear feeding motor 113. The movable end is connected to one end of the lead feeding long rod 1162. The other end of the lead feeding long rod 1162 is connected to the linkage fixing bracket 1163. The linkage fixing bracket 1163 is fixedly arranged on the front feeding plate 112. The distance between the fixed end and the movable end of the lead feeding connecting rod 1161 controls the moving stroke of the lead feeding long rod 1162, thereby controlling the cutting length of the lead bar. The moving stroke of the lead feeding long rod 1162 is less than the distance between the front feeding motor 110 and the rear feeding motor 113. When the rear feeding motor 113 starts, the lead feeding connecting rod 1161 rotates to drive the lead feeding long rod 1162 to move. With the front lead feeding mechanism in a fixed state, the movement of the lead feeding long rod 1162 drives the rear feeding plate 115 to slide along the bottom plate mechanism, thereby moving the lead bar from the first set position to the second set position.

[0083] During the implementation of the lead feeding device 11, the lead bar 102 is located in the front feeding groove 1120 and the rear feeding groove 1150. The front feeding cylinder 111 and the rear feeding cylinder 114 are started to press the lead bar 102 tightly in the front feeding groove 1120 and the rear feeding groove 1150. The front feeding motor 110 is started to drive the front feeding plate 112 and the rear feeding plate 115 to move towards the pressing and cutting device 17, thereby driving the lead bar 102 to move and moving the lead bar 102 to the first set position, i.e., the cutting position, to complete the initial lead feeding step of the lead bar 102. Then the front feeding motor 110 stops running, the front feeding cylinder 111 resets, and the rear feeding motor 113 is started to drive the lead bar 102 to move to the second set position, completing the final lead feeding step of the lead bar 102. The distance between the first set position and the second set position is the cutting length of the lead bar.

[0084] The pressing and cutting device 17 includes a pressing and cutting machine frame 170, a lead pressing mechanism, and a lead cutting mechanism. The pressing and cutting machine frame is fixedly arranged on the lead coiling machine table 13. The lead pressing mechanism and the lead cutting mechanism are respectively fixedly arranged on the lead coiling machine table 13. The lead pressing mechanism includes a lead pressing machine frame 172, a lead pressing cylinder 171, a lead pressing slide plate 173, and a lead pressing block 174.

The lead pressing slide plate 173 is fixedly arranged on the output shaft of the lead pressing cylinder 171, and the lead pressing slide plate 173 is slidably connected to the lead pressing machine frame 172. The lead pressing block 174 is arranged on the lower end face of the lead pressing slide plate 173. When the lead pressing cylinder 171 is started, it drives the lead pressing slide plate 173 to move downward so that the lead pressing block 174 presses the lead bar 102 on the lead coiling table 14 to prevent the end of the lead bar 102 far from the cutting edge from lifting when the lead cutting mechanism cuts the material.

[0085] The lead cutting mechanism includes a lead cutting frame 176, a lead cutting cylinder 175, a lead cutting slide plate 177, a lead cutting press block 178, and a lead cutting knife 179. The lead cutting frame 176 is fixedly installed on the pressing and cutting frame 170. The lead cutting slide plate 177 is fixedly installed on the output shaft of the lead cutting cylinder 175 and is slidably connected to the lead cutting frame 176. The lead pressing block 174 is arranged on the lower end surface of the lead pressing slide plate 173. The lead cutting press block 178 and the lead cutting knife 179 are respectively fixedly installed on the lower end surface of the lead cutting slide plate 177. A notch 141 is provided on the lead coiling table 14, and the notch 141 is opposite to the lead cutting knife 179. During material cutting, the lead cutting press block 178 pre-presses the material to prevent the fracture from bending downward under the action of the lead cutting knife 179 when the lead cutting knife 179 cuts the material, which affects the subsequent lead coiling efficiency and reject rate.

[0086] During the implementation of the pressing and cutting device 17, the lead feeding device 11 moves the lead bar 102 to the second set position. At this time, the lead pressing cylinder 171 is activated, and the lead pressing block 174 presses the lead bar 102 against the lead coiling table 14. At the same time, the lead cutting cylinder 175 is activated, and the lead cutting press block 178 presses the lead bar 102 against the lead coiling table 14. The lead cutting cylinder 175 continues to operate, and the lead cutting knife 179 inserts into the notch 141 to cut the lead bar 102. The lead pressing block 174 and the lead cutting press block 178 are located at both ends of the cut lead bar 102 to ensure the flatness of the lead bar 102, which is convenient for subsequent lead coiling and effectively reduces the reject rate of the lead sinker.

[0087] The feeding device 12 includes a material tray 121 and a feeding mechanism. The material tray 121 is provided with a conduit 120. The conduit 120 is driven by the feeding mechanism to move to the lead coiling table 14. The material tray 121 is fixedly installed on the lead coiling machine table 13 through a material tray fixing frame 122. The feeding mechanism includes a conduit motor 126, a limiting wheel 129, a swing rod 124, and a fixing frame 123. The conduit motor 126 is fixedly installed on the lower plate 130. The lower plate 130 is fixedly installed on the lead coiling machine table 13. The lead coiling table 14 is fixedly installed on the lower plate 130. The output shaft of the conduit motor 126 is fixedly provided with a feeding main gear 127. One end of the swing rod 124 is connected to the fixing frame 123, and the other end is connected to the limiting wheel 129. The limiting wheel 129 is located above the feeding main gear 127. The conduit 120 is fastened between the limiting wheel 129 and the feeding main gear 127. When the conduit motor 126 is activated, it drives the feeding main gear 127 to rotate, and then drives the conduit 120 located between the feeding main gear 127 and the fixed wheel 412 to move forward, realizing the transportation of the conduit 120.

[0088] The feeding device 12 further includes a feeding spring 125. One end of the feeding spring 125 is connected to the swing rod 124, and the other end is connected to the lower plate 130 through a fixer. Through the feeding spring 125, during the transportation of the conduit 120, the limiting wheel 129 and the feeding main gear 127 always maintain a relatively stable gap, realizing the continuous and stable transportation of the conduit 120.

[0089] The feeding device 12 further includes a guiding tube 128 which is arranged between the material tray 121 and the lead coiling table 14. The guiding tube 128 is provided with a feeding hole, and the conduit 120 is located in the feeding hole and moves along the feeding hole, thereby restricting the moving direction of the conduit 120 and preventing problems such as deviation during the conduit 120, which may cause subsequent cutting of the material and reduce the lead coiling effect. A cavity is arranged at the position of the guiding tube 128 where the main feeding gear 127 is located, and the main feeding gear 127 is located in the cavity to achieve the conveyance of the conduit 120.

[0090] The pipe cutting device 18 includes a pipe cutting transverse movement mechanism 181, a pipe cutting longitudinal movement mechanism 182, a pipe cutting plate 183 and a pipe cutting knife 184. The pipe cutting knife 184 is located between the feeding device 12 and the lead coiling table 14 and is used for cutting the conduit 120. The pipe cutting knife 184 is fixedly arranged at one end of the pipe cutting plate 183, and the other end of the pipe cutting plate 183 is connected to the pipe cutting transverse movement mechanism 181. The pipe cutting transverse movement mechanism 181 is connected to the pipe cutting longitudinal movement mechanism 182, and the pipe cutting longitudinal movement mechanism 182 is fixedly connected to the lead coiling machine table 13. When the pipe cutting transverse movement mechanism 181 is started, it drives the pipe cutting plate 183 to move horizontally, controls the distance between the pipe cutting knife 184 and the lead coiling table 14, and further controls the cutting length of the conduit. When the pipe cutting longitudinal movement mechanism 182 is started, it drives the pipe cutting transverse movement mechanism 181 and the pipe cutting knife 184 to move up or down synchronously to achieve the cutting of the conduit 120.

In the horizontal direction, that is, the x direction shown in the figure, the guide pin 154 is opposite to the conduit 120, and the guide pin 154 can be in contact with the conduit 120 when in the working state. When the guide pin motor 151 is started, the output shaft of the guide pin motor 151 rotates, and the rotation of the output shaft of the guide pin motor 151 drives the guide pin moving block 153 to slide, thereby driving the guide pin 154 to move.

[0092] The lead folding device 16 includes a lead folding mechanism 160, a forming mechanism 161, and a lead winding mechanism 162. The lead folding mechanism 160 includes a lead folding cylinder 1601. The output shaft of the lead folding cylinder 1601 is connected to a lead folding fixed plate 1603.

After the lead folding cylinder 1601 is started, it drives the lead folding fixed plate 1603 to slide, and then drives the lead folding rack 1602 to slide.

[0093] The lead folding mechanism 160 further includes a lead folding mounting frame 1605. The lead folding mounting frame 1605 is fixedly arranged on the lower plate 130. A rotating rod 1606 is rotatably arranged in the lead folding mounting frame 1605. A guide pin 154 passes through the rotating rod 1606 and is movably connected to the rotating rod 1606. The guide pin 154 and the rotating rod 1606 move independently. A lead folding gear 1607 is fixedly arranged at one end of the rotating rod 1606. A folding plate 1608 is fixedly arranged at the other end of the rotating rod 1606. The lead folding gear 1607 is meshed with the lead folding rack 1602. The folding plate 1608 is provided with a flat surface. When the lead strip 102 is fed, the flat surface of the folding plate 1608 is parallel to the lead winding table 14. The lead feeding device 11 moves the lead strip 102 to the flat surface of the folding plate 1608, that is, the second set position, so that the lead strip 102 is placed on the flat surface of the folding plate 1608. The conduit 120 is located above the lead strip 102 and between the lead winding table 14 and the folding plate 1608. The lead folding mechanism 160 operates to control the folding plate 1608 to flip, so as to pre-fold the lead strip 102 located on the flat surface of the folding plate 1608.

[0094] The forming mechanism includes a forming machine frame 1612, a forming cylinder 1611, and a forming slide plate 1613. The forming machine frame 1612 is fixedly arranged on the cutting press frame. The forming slide plate 1613 is fixedly arranged on the output shaft of the forming cylinder 1611, and the forming slide plate 1613 is slidably connected to the forming machine frame 1612. A forming groove 1614 is fixedly arranged at the lower end of the forming slide plate 1613. The forming groove 1614 presses and wraps the pre-folded lead strip 102 on the conduit 120 to achieve the forming process, which is convenient for the subsequent lead winding process of the lead winding mechanism 162.

[0095] The lead coiling mechanism 162 includes a material pressing motor 1623, a material pressing cylinder 1624, a lead coiling machine frame 1620, and a lead pressing seat 1626. The lead coiling machine frame 1620 is fixedly installed on the lead coiling machine table 13. The material pressing motor 1623 is fixedly installed on the lead coiling machine frame 1620. A lead coiling gear 1627 is fixedly installed on the output shaft of the material pressing motor 1623. The lead pressing seat 1626 is rotatably connected to the lead coiling machine frame 1620. A lead coiling slide rail 1621 is slidably arranged on the lead pressing seat 1626. Lead coiling racks 1622 and a material pressing strip 1625 are respectively arranged at both ends of the lead coiling slide rail 1621. The material pressing strip 1625 is located above the lead coiling table 14. A material pressing cylinder 1624 is fixedly installed on the lead coiling machine frame 1620. The material pressing cylinder 1624 is located above one side of the lead pressing seat 1626, and the material pressing cylinder 1624 and the material pressing strip 1625 are located on the same side of the lead pressing seat 1626. The lead coiling rack 1622 is meshed and connected with the lead coiling gear 1627. When the material pressing motor 1623 is started, it drives the lead coiling gear 1627 to rotate, and then drives the material pressing strip 1625 to move through the movement of the lead coiling slide rail 1621. During the implementation of the lead coiling mechanism 162, when the material pressing motor 1623 is started, the material pressing strip 1625 is moved above the formed lead weight. When the material pressing cylinder 1624 is started, the material pressing strip 1625 is abutted against the formed lead weight. When the material pressing motor 1623 continues to operate, the linear movement of the material pressing strip 1625 causes the formed lead weight to roll and be roll-pressed under the pressure of the material pressing strip 1625, realizing the lead coiling process of the lead weight. During the rolling process of the formed lead weight in this embodiment, the diameter gradually increases. At this time, the material pressing cylinder 1624 gradually resets to keep the material pressing strip 1625 always abutted against the outer surface of the lead weight but the pressure is not too large, achieving the purpose of automatic lead coiling.

[0096] An outlet 131 and an outlet plate 132 are provided on the lead coiling machine table 13. The outlet 1301 is located at one end of the lead coiling table 14 close to the lead feeding device 11. The outlet plate 132 is arranged inside the lead coiling machine table 13. The outlet plate 132 is of an inclined structure. The feeding end of the outlet plate 132 is located below the outlet 131. The discharging end of the outlet plate 132 is located outside the lead coiling machine table 13 and above the feeding conveyor line 21. The lead weight falls from the outlet 131 to the discharging end, and under the action of gravity, the lead weight moves to the discharging end and falls into the feeding conveyor line 21 through the discharging end.

[0097] During the implementation of the lead coiling machine 1, the lead feeding device 11 moves the lead bar to the second set position, and the lead pressing mechanism and the lead cutting mechanism are started synchronously. The lead pressing block 174 and the lead cutting block 178 press the lead bar on the lead coiling table 14 respectively. After the lead cutting knife 179 cuts the lead bar, the front feeding air cylinder 111 is started, the rear feeding air cylinder 114 is reset, the rear feeding motor 113 rotates reversely to reset, and the front feeding motor 110 rotates reversely to reset, driving the lead bar to move reversely to prepare for the next lead feeding step. When the lead bar is at the second set position, the guide pin motor 151 is started, driving the guide pin 154 to move towards the feeding device until the guide pin 154 abuts against the end face of the conduit 120. At this time, the conduit motor 126 is started, and the guide pin motor 151 runs reversely. With the guide pin 154 always in contact with the conduit 120, the conduit 120 moves gradually until it is located above the lead bar 102. At this time, the lead folding mechanism 160 operates, and under the action of the folding plate 1608, the lead bar 102 undergoes pre-folding, that is, preliminary folding. The forming mechanism operates to press and wrap the pre-folded lead bar 102 around the conduit 120 to complete the forming process. At this time, the pipe cutting device 18 is started to cut the conduit 120. The conduit motor 126 rotates reversely, driving the cut conduit 120 to retreat a certain distance away from the pipe cutting knife 184 to prevent the end of the cut conduit 120 from being deformed under the downward movement of the pipe cutting knife 184 when the pipe cutting device 18 is reset. After the pipe cutting device 18 is reset, the guide pin motor 151 is reset, causing the guide pin 154 to disengage from the contact state with the conduit 120, thereby preventing the end of the conduit 120 from contacting the guide pin 154 and wearing during lead coiling. The pressing motor 1623 is started to move the pressing bar 1625 to above the formed lead weight. The pressing air cylinder 1624 is started to make the pressing bar 1625 abut against the formed lead weight. The pressing motor 1623 continues to operate, and the pressing bar 1625 rolls the formed lead weight. When the pressing bar 1625 is about to contact the lead pressing block 174, the lead pressing air cylinder 171 is reset. The pressing motor 1623 continues to operate. When the pressing bar 1625 is about to contact the lead cutting block 178, the lead cutting air cylinder 175 is reset. The pressing motor 1623 continues to operate to complete the lead coiling process. The pressing motor 1623 pushes the formed lead weight into the discharge port 131 and then into the discharge plate 132. Under the action of gravity, the lead weight falls along the discharge plate 132 into the feeding conveyor line 21.

[0098] A number of lead coiling machines 1 are provided. In this embodiment, four sets of lead coiling machines 1 are arranged to form a lead coiling machine group. The lead coiling machines 1 are arranged in pairs. The feeding conveyor line 21 is located between the lead coiling machines 1. The semi-finished lead weights produced by a number of lead coiling machines 1 all fall into the feeding conveyor line 21. The feeding conveyor line 21 is connected to the front vibrating disk 22. The lead weights are conveyed to the front vibrating disk 22 through the feeding conveyor line 21. In this embodiment, the lead coiling machines 1 are respectively controlled by their own independent controllers. At the same time, corresponding interfaces and protocols are left to facilitate docking with the main controller and system expansion requirements.

[0099] The front vibrating tray 22 includes a guiding groove 221, the width of the guiding groove 221 matches the width of the plumb bob, and the guiding groove 221 can preliminarily eliminate problem plumb bobs of abnormal shapes, such as plumb bobs that are not successfully wound with lead initially, or products where the tail of the lead bar is not successfully wound with lead. Products with overly defective shapes cannot be conveyed forward along the guiding groove 221 and thus fall back to the front vibrating tray 22. Plumb bobs with acceptable shapes are transported by the guiding groove 221 to the sorting device 3 to achieve preliminary sorting. The front vibrating tray 22 realizes the purpose of conveying plumb bobs one by one, facilitating subsequent sorting processes.

[0100] The sorting device 3 is located between the front vibrating tray 22 and the drying tunnel device 4. The sorting device 3 includes a sorting frame 31, a vision camera 32, a sorting bar 37, a sorting mechanism, and a defective product collection device. The vision camera 32 and the sorting bar 37 are fixedly arranged on the sorting frame 31. The acquisition direction of the vision camera 32 faces the semi-finished plumb bobs located in the guiding groove 221. There is a gap between the sorting bar 37 and the guiding groove 221, and the semi-finished plumb bobs are sequentially conveyed along the guiding groove 221 and the sorting bar 37.

[0101] The vision camera acquires images of the screening vision area. The vision camera is connected to the upper industrial control computer through Ethernet. The industrial control computer is configured with a detection algorithm. The detection algorithm identifies the images of the screening vision area acquired by the vision camera and the shapes of the plumb bobs in the images, and feeds the identification results back to the main controller. The main controller stores the shapes of qualified plumb bobs internally, and the main controller judges whether the shape of the current plumb bob is qualified by comparison.

[0102] The sorting mechanism includes a sorting motor 38, a sorting block 36, and a sorting plate 35. The sorting motor 38 is fixedly arranged on the sorting frame 31.

The length of the sorting block 36 is greater than the length of the semi-finished plumb bob. The sorting plate 35 is connected to the sorting frame 31. The sorting frame 31 is located below the sorting block 36, and the sorting plate 35 is inclined. The main controller is communicatively connected to the sorting motor 38. When it is determined that the semi-finished plumb bob is a problem plumb bob, the main controller controls the sorting motor 38 to start, and the sorting block 36 rotates, causing the semi-finished plumb bob on the sorting block 36 to fall onto the sorting plate 35 and then fall into the defective product collection device through the sorting plate 35. When it is determined that the semi-finished plumb bob is a qualified plumb bob, the semi-finished plumb bob continues to be conveyed, and the semi-finished plumb bob is conveyed to the drying tunnel device 4 through the sorting bar 37.

[0103] The drying tunnel device 4 includes a heating chamber 41, a ventilation duct 42, a drying tunnel component 43, and a drying tunnel conveyor line 44.

The temperature of the heating chamber 41 is closed-loop controlled by the number of heating rods and the running speed of the blower 412. The heating chamber temperature sensor 413 detects the temperature of the heating chamber 41, and the heating chamber temperature sensor 413 feeds back the detected temperature value to the main controller. The main controller controls the temperature of the heating chamber 41 within the set range by controlling the running speed of the blower 412.

A baking chamber 433 is provided between the upper baking tunnel 431 and the lower support base 432. A baking tunnel conveyor line 44 is arranged in the baking chamber 433. In this embodiment, the upper baking tunnel 431 includes a front chamber 4311, a middle chamber 4312, and a rear chamber 4313. The designs of the front chamber 4311, the middle chamber 4312, and the rear chamber 4313 ensure that the temperature of the upper baking tunnel 431 is uniform in the length direction, so that the temperature of the upper baking tunnel 431 is at a relatively stable value, avoiding too low temperatures at both ends, which may affect the heating of the conduits of the semi-finished lead weights and the subsequent conduit winding process.

[0106] The structures of the front chamber 4311, the middle chamber 4312, and the rear chamber 4313 are the same. Taking the front chamber 4311 as an example for illustration, air outlet cross plates 4312 are symmetrically arranged on both sides of the front chamber 4311. An air outlet 4313 is formed between the two groups of air outlet cross plates 4312. The hot air in the front chamber 4311 flows from the air outlet 4313 to the baking chamber 433. In this embodiment, the air outlet cross plate 4312 includes an inclined plate, and the inclined plates of the two groups of air outlet cross plates 4312 form a V shape, so as to guide the flow direction of the hot air.

The first ventilation pipe 421 communicates with the front chamber 4311, the second ventilation pipe 422 communicates with the middle chamber 4312, and the third ventilation pipe 423 communicates with the rear chamber 4313. Through the first ventilation pipe 421, the second ventilation pipe 422, and the third ventilation pipe 423, the hot air in the heating chamber 41 is respectively transmitted to the front chamber 4311, the middle chamber 4312, and the rear chamber 4313, and is transmitted to the drying chamber 433 through the air outlet 4313 to heat the ducts of the semi-finished lead weights located on the drying tunnel conveyor line 44.

[0109] The drying tunnel device 4 further includes an adjustment mechanism for controlling the air volume of the first ventilation pipe 421, the second ventilation pipe 422, and the third ventilation pipe 423.

[0111] The winding device 5 further includes a water pump 52 and a water storage tank 51. The water storage tank 51 is located on one side of the cooling water tank 53. The water storage tank 51 is filled with normal temperature water or cooling water. The water pump 52 is arranged in the water storage tank 51.

[0129] Step 1.3: The guide pin device 15 and the feeding device 12 operate to transport the catheter 120 above the lead bar 102 to be coiled.

[0130] Step 1.4: The lead folding mechanism 160 is started to pre-fold the head end of the lead bar 102 to be coiled in step 1.3 on the catheter 120. The forming mechanism presses and wraps the lead bar 102 to be coiled on the catheter 120 to make a formed lead sinker. The tube cutting device 18 is started to cut off the catheter 120 and reset. The guide pin device 15 and the feeding device 12 are reset. The coiling mechanism 162 rolls the formed lead sinker to make the lead sinker automatically coil lead and make a semi-finished lead sinker.

[0131] Step 1.5: The semi-finished lead sinker falls into the discharge plate 132 for discharging.

[0132] Step 2: The front vibrating disk 22 preliminarily screens the semi-finished lead sinkers.

[0133] The lead coiling machine 1 transports the semi-finished lead sinkers to the front vibrating disk 22 through the feeding conveyor line 21. The width of the guiding groove 221 of the front vibrating disk 22 matches the width of the lead sinker. The semi-finished lead sinkers with good appearance that meet the setting of the guiding groove 221 are transported through the guiding groove 221 and step 3 is executed. The defective lead sinkers that do not meet the requirements are collected in the defective area.

[0134] Step 3: The sorting device 3 screens the semi-finished lead weights;

[0135] Step 3.1: The vision camera 32 captures images of the screening field of view;

[0136] Step 3.2: Determine whether the semi-finished lead weight enters the screening field of view. If so, execute Step 3.3; if not, execute Step 3.1;

[0137] Step 3.3: Determine whether there are shape defects in the shape of the semi-finished lead weight. If so, the semi-finished lead weight is determined to be a defective product, and execute Step 3.4; if not, the semi-finished lead weight is determined to be a good product. The good products are transported to the drying tunnel device 4, execute Step 4, complete one screening, and then execute Step 3.1 to repeat the screening process of the semi-finished lead weights;

[0138] Step 3.4: Remove the defective products. The main controller controls the sorting motor 38 to start, and the sorting block 36 rotates to make the defective products fall into the defective product collection device;

[0139] Step 4: The main controller controls the drying chamber to the target temperature, such as 200 degrees, and the drying tunnel device 4 heats the conduit of the lead weight;

[0140] Step 5: The winding device 5 cools the conduit of the semi-finished lead weight through normal temperature or cooling water to wind it;

[0141] Step 6: The drying device 6 dries the moisture of the wound lead weight;

[0142] Step 7: The dried lead weights are transported to the storage device 7. The storage device 7 transports the lead weights to the polishing box 81. The polishing and separation device 8 polishes the lead weights. After polishing, the polished wooden boards and the finished lead weights are separated through the separation box 84. The polished wooden boards are collected into the wooden board collection box 87, and the manipulator transfers the polished wooden boards to the polishing box 81;

[0143] Step 8: The finished lead weights fall into the rear vibrating disk 91. After being counted by the counting sensor 95, the finished lead weights fall into the finished product collection box 94 for collection.

[0144] The mass of the finished lead weight is the sum of the mass of the lead bar and the mass of the conduit. Since the mass of the lead bar is much larger than the mass of the conduit, when calculating the mass of the lead weight, the mass of the conduit is ignored and the mass of the lead bar is used as the standard. The width of the cross-section of the lead weight is W0, the height is H0, and the length is L. The density of the lead bar is ρ. After the lead bar is selected, the parameters of W0, H0, and ρ are known values. Therefore, the mass of the lead weight is only related to the cutting length. The cutting length of the lead bar 102 is related to the rotation angle of the rear feeding motor 113. To produce lead weight products with different mass specifications, only the rotation angle of the rear feeding motor needs to be changed.

[0145] The calculation formula for the cutting length of the lead bar 102 in Step 1.2 is:

[0146] The length of the lead feeding long rod 1162 of the lead feeding linkage mechanism is set as G, the length of the lead feeding connecting rod 1161 is set as R, and the initial angle of the lead feeding connecting rod 1161 relative to the perpendicular line of the rotation center is set as θ0; the angular rotation direction is negative counterclockwise relative to the perpendicular line of the rotation center and positive clockwise relative to the perpendicular line of the rotation center. The distance of the end of the lead feeding long rod 1162 at the initial position relative to the projection of the rotation center on the displacement plane is set as S0, the target angle of the lead feeding connecting rod 1161 relative to the perpendicular line of the rotation center is set as θ1, and the distance of the end of the lead feeding long rod 1162 at the target position relative to the projection of the rotation center on the displacement plane is set as S1. The cutting length of the lead strip is set as L, and L = S1 - S0; the distance between the rotation center of the lead feeding connecting rod 1161 and the ends of the lead feeding long rod 1162 at the initial position and the target position is set as △R. The ends of the lead feeding long rod 1162 at the initial position and the target position are at Figure 19 the set positions with known arrow directions as shown. The rotation angle of the output shaft connected to the rear feeding motor 113 is set as θ, and θ = θ0 - θ1. The reduction ratio of the reducer connected to the motor shaft and the output shaft of the rear feeding motor 113 is n:1. The operating angle of the motor shaft of the rear feeding motor 113 is set as δ, and δ = n×θ. Thus, the calculation formula (1) can be obtained:

[0147] In the calculation formula (1), G, R, △R, and θ0 are known set values. From the calculation formula (1), the relationship between L and δ can be obtained. In actual production, the value of δ is adjusted according to the required value of L, and then the cutting length of the lead strip 102 is adjusted by adjusting the value of δ.

[0148] According to the relationship among δ, θ0, and θ1, the calculation formula (2) for the lead weight mass M and the operating angle δ of the motor shaft of the rear feeding motor 113 can be obtained:

[0149]

[0150]

[0151] According to the calculation formula (2), lead weight products with different mass specifications can be produced by changing the operating angle of the motor shaft of the rear feeding motor 113.

[0152] The operating method of the guide pin device 15 and the feeding device 12 in step 1.3:

[0153] Such as Figure 20As shown in the figure, the position A1 is the initial position of the guide pin 154, the position A2 is the separation position of the guide pin 154 and the catheter 120, the position A3 is the positioning position of the tube cutter, and the position A4 is the initial position of the catheter 120 and at the same time the contact position of the guide pin 154 and the catheter 120. First, the guide pin moves a distance of (C + B + A) from the position A1 to the position A4, and at this time, the guide pin contacts the end face of the catheter. After that, the guide pin and the catheter move synchronously a distance of (A + B) from the position A4 to the position A2, and maintain real-time contact during this period.

[0154] The method for judging whether the semi-finished lead sinker enters the screening vision area in step 3.2 includes the following steps:

[0155] Step 3.2.1: The area threshold of the standard semi-finished lead sinker occupying the visual pixels of the vision camera 32 is set to S0, and the value of S0 is set according to actual needs. In this embodiment, S0 is set to 200;

[0156] Step 3.2.2: The vision camera 32 collects an image of the screening vision area, and this image is set as P1. P1 is grayscale processed to obtain a grayscale image, and the grayscale image is set as P2;

[0157] Step 3.2.3: According to the grayscale image P2, threshold segmentation is used to retrieve the area S1 with a grayscale value > G1. In this embodiment, the pixels with a grayscale value > G1 in the grayscale image represent the pixels of the lead sinker in the grayscale image. The values of G1 and S1 are set according to actual needs. In this embodiment, G1 is set to 100;

[0158] Step 3.2.4: Judge whether S1 is greater than S0. If so, execute step 3.2.5. If not, it is determined that the semi-finished lead sinker has not entered the screening vision area, and execute step 3.2.2;

[0159] Step 3.2.5: Judge whether there is a lead sinker at the boundary of P2;

[0160] If the grayscale value of the boundary of P2 > G1, it is determined that there is a lead sinker at the boundary of P2, indicating that the lead sinker has not completely entered the screening vision area, then execute step 3.2.2. If the grayscale value of the boundary of P2 < G1, it is determined that there is no lead sinker at the boundary of P2, indicating that the lead sinker has completely entered the screening vision area. Identify the defects of the lead sinker in P1, and then execute step 3.3.

[0161] The method for judging whether there are shape defects in the shape of the semi-finished lead sinker in step 3.3 uses the image P1 corresponding to the grayscale image P2 in which it has been determined that the lead sinker has completely entered the screening vision area in step 3.2. The image P1 is a color image. In this method, the colors of the catheter 120 and the lead strip 102 on the lead sinker are different, which is convenient for color acquisition. Preferably, the catheter 120 is set to blue and the lead strip 102 is gray. The judging method includes the following steps:

[0162] Step 3.3.1: Obtain the image P1 through step 3.2;

[0163] Step 3.3.2: Determine whether gray or blue is recognized in image P1. If both gray and blue are recognized in P1, it indicates that the plumb weight has the catheter 120 and the lead bar 102. At this time, execute Step 3.3.3. Otherwise, it is considered that there is a defect of missing one of the catheter 120 and the lead bar 102 in the plumb weight, and the plumb weight in image P1 is determined to be a defective product, then execute Step 3.4;

[0164] Step 3.3.3: Use the color extraction algorithm (RGB to Gray) to extract the lead region ROI1, the blue region ROI2 and the merged region ROI3 of the plumb weight in P1;

[0165] The merged region ROI3 is Figure 26 the region formed by the dotted line in;

[0167] Step 3.3.5: Draw the rectangular central axes L1, L2, and L3 in the same direction as the long side of REC3 according to the minimum rectangles REC1, REC2, and REC3 respectively;

[0168] Step 3.3.6: Determine whether the linear angles of L1, L2, and L3 are close to coincidence. If so, execute Step 3.3.7. When the linear angles of L1, L2, and L3 are close to coincidence, the catheter 120 is at the axial center position of the lead bar 102. Otherwise, it is considered that there is a defect of misalignment of the catheter 120 in the plumb weight, and the plumb weight in image P1 is determined to be a defective product, then execute Step 3.4;

[0169] Step 3.3.7: At the two long-side boundaries of the minimum rectangle REC1, find the lines L4 and L5 in the lead region ROI1 through the Hough line;

[0170] Step 3.3.8: Determine whether both the linear angle and the length of L4 and L5 are close. If so, it is considered that the parallelism on both sides of the long side of the lead bar 102 is good. At this time, execute Step 3.3.9. Otherwise, it is considered that there is a defect of strange shape in the lead bar 102, and the plumb weight in image P1 is determined to be a defective product, then execute Step 3.4;

[0171] Step 3.3.9: At the two short-side boundaries of the minimum rectangle REC1, find the lines L6 and L7 in the lead region ROI1 through the Hough line;

[0172] Step 3.3.9: Determine whether the linear angles and lengths of L6 and L7 are both close. If so, it is considered that the parallelism of the short sides on both sides of the lead bar 102 is good, and at this time, execute Step 3.3.10. If not, it is considered that the lead bar 102 has a defect of strange shape, determine that the plumb bob in the image P1 is a defective product, and execute Step 3.4;

[0173] Step 3.3.10: Determine whether the lengths of L6 and L7 are within the H interval. The range of the H interval is set according to actual needs. If so, it is considered that the outer diameter of the plumb bob meets the set requirements and there is no under-rolling or over-rolling. At this time, execute Step 3.3.11. If not, it is considered that the plumb bob has a defect of under-rolling or over-rolling, determine that the plumb bob in the image P1 is a defective product, and execute Step 3.4;

[0174] Step 3.3.11: Determine whether ROI2 is two independent regions ROI4 and ROI5. If so, it is considered that both sides of the plumb bob are equipped with the conduit 120. At this time, execute Step 3.3.12. If not, it is considered that the plumb bob has a defect of missing conduit, determine that the plumb bob in the image P1 is a defective product, and execute Step 3.4;

[0175] Step 3.3.12: Calculate the effective lengths of the central axis L2 in the regions of ROI4 and ROI5, which are d1 and d2 respectively;

[0176] Step 3.3.13: Determine whether d1 and d2 are within the T interval. If so, it is considered that the lead bar is in the middle of the conduit, determine that the plumb bob in the image P1 is a high-quality product, and the high-quality product is conveyed to the drying tunnel device 4, execute Step 4, complete the detection of the appearance defects of the semi-finished plumb bob once, and wait for the next detection of the appearance defects of the semi-finished plumb bob. If not, it is considered that the plumb bob has a defect of missing conduit, determine that the plumb bob in the image P1 is a defective product, and execute Step 3.4. The range of the T interval is set according to actual needs and is 20 - 50 mm in this embodiment.

[0177] The method for the main controller to control the drying chamber at the target temperature in Step 4 includes the following steps:

[0178] Step 4.1: Set the target temperature of the drying chamber. The target temperature is set to T0, and the target temperature T0 is assigned to the target temperature T01 of the heating chamber and the target temperature T02 of the air outlet. When the heating chamber reaches the target temperature T01 and the air outlet reaches the target temperature T02, the drying chamber reaches the target temperature T0. Set the time t0. When the heating chamber reaches the target temperature T01, after t0, the drying chamber reaches the target temperature T0;

[0179] Step 4.2: Set the actual temperature of the heating chamber detected by the heating chamber temperature sensor 413 as T1, set the difference between the actual temperature value of the heating chamber and the target temperature of the heating chamber as ΔT1, ΔT1 = |T1 - T01|, set the difference threshold between the actual temperature value of the heating chamber and the target temperature of the heating chamber as ΔT01, and ΔT01 is specifically set according to the actual adjustment accuracy. When the adjustment accuracy is high, ΔT01 is set small, such as 5 degrees; when the requirement for adjustment accuracy is not high, ΔT01 is set large, such as 10 degrees. If ΔT1 is not greater than ΔT01, execute Step 4.3. If ΔT1 is greater than ΔT01, start the heating chamber temperature adjustment program to re-adjust until it satisfies that ΔT1 is not greater than ΔT01;

[0180] Step 4.3: Set the actual temperature of the air outlet detected by the air outlet temperature sensor 4314 as T2, set the difference between the actual temperature value of the air outlet and the target temperature of the air outlet as ΔT2, ΔT2 = |T2 - T02|, set the difference threshold between the actual temperature value of the heating chamber and the target temperature of the air outlet as ΔT02, and ΔT02 is specifically set according to the actual adjustment accuracy. When the adjustment accuracy is high, ΔT02 is set small, such as 5 degrees; when the requirement for adjustment accuracy is not high, ΔT02 is set large, such as 10 degrees. If ΔT2 is not greater than ΔT02, execute Step 4.4. If ΔT2 is greater than ΔT02, execute Step 4.5;

[0181] Step 4.4: The actual temperature values of each position in the drying chamber detected by the drying channel temperature sensor 4331 are T3n, n = 1, 2... n, where n is the number of drying channel temperature sensors 4331 in the drying chamber. Set the difference between T3n and the target temperature T0 of the drying chamber as ΔT3n, ΔT3n = |T3n - T0|. Set the difference threshold between the actual temperature value of the drying chamber and the target temperature T0 of the drying chamber as ΔT03, and ΔT03 is set according to the actual situation. If ΔT3n is not greater than ΔT03, it is considered that the overall temperature of the drying chamber is in an equilibrium state. At this time, the drying channel device 4 heats the conduit of the plumb bob, and at the same time execute Step 4.2 to continuously ensure the temperature equilibrium. If ΔT3n is greater than ΔT03, adjust the rotation speed of the blower 412 and execute Step 4.2 until it satisfies that ΔT3n is not greater than ΔT03;

[0182] Step 4.5: Determine whether the temperature adjustment times out;

[0183] When the heating chamber reaches the target temperature T01, the timer starts timing. The timer detects the real-time time as t1. Compare t1 and t0. If t1 is not greater than t0, control the adjustment mechanism to adjust the opening degree of the valve 45 through the air outlet temperature adjustment program, and then control the air intake volume of the heating chamber until it satisfies that ΔT2 is not greater than ΔT02. If t1 is greater than t0, it is considered that the target temperature T0 of the drying chamber is set too low. Increase the value of T0, adjust the relevant parameters, and execute Step 4.1.
