Description

Technical Field

[0001] The present invention relates to the technical field of heating tube crimping, and particularly to an automatic baking pan heating tube crimping machine. Background Art

[0002] In modern household appliances and industrial heating equipment, the baking pan is an indispensable part. It not only needs to provide uniform heating performance, but also ensure safety and reliability under long-term use. One of the key components inside the baking pan is the heating tube, and the quality of its installation is directly related to the heating efficiency, service life and safety of the baking pan.

[0003] The traditional method for installing the baking pan heating tube mainly relies on manual operation. Specifically, workers need to manually place the baking pan on the working platform of the crimping machine, then place the heating tube at the preset position on the baking pan, and finally manually control the crimping machine to complete the fixed connection between the heating tube and the baking pan. When operating in this way, due to the lack of a precise positioning device for manual placement, the heating tube may not be accurately placed at the predetermined position, resulting in uneven heating or affecting the appearance. Moreover, it is difficult to ensure the consistency of each installation by manual operation, making the product quality unstable, increasing the defective rate. In addition, manual operation takes a long time, restricting the production speed and increasing the cost. Summary of the Invention

[0004] In view of this, the present invention provides an automatic baking pan heating tube crimping machine, which can solve the disadvantages of the traditional method for installing the baking pan heating tube, namely, the lack of a precise positioning device for manual placement, the difficulty in ensuring the consistency of each installation by manual operation, the long time-consuming of manual operation, the restriction of production speed, and the high cost.

[0005] The technical implementation solution of the present invention is: an automatic baking tray heating tube press, which includes a conveyor. Rubber strips are evenly spaced on the conveyor belt of the conveyor, and the rubber strips are used to drive the baking tray to move. A guiding mechanism for guiding the baking tray is arranged on the conveyor, and a supporting mechanism is arranged on the conveyor. A first mounting plate is arranged on the supporting mechanism, and a heating wire is arranged at the bottom of the first mounting plate. The heating wire is used to heat-melt the position of the preset heating tube on the baking tray. A limiting block for limiting the heating tube is also arranged on the supporting mechanism. A first electric push rod is arranged at the bottom of the limiting block, and a supporting plate for supporting the heating tube is connected to the telescopic rod of the first electric push rod. A blocking mechanism is also arranged at the bottom of the limiting block. When the lowermost heating tube drops, the blocking mechanism is used to block the remaining heating tubes from dropping. A second mounting plate is also arranged on the supporting mechanism. A pressing frame is slidably arranged at the bottom of the second mounting plate, and the pressing frame is used to press the heating tube on the baking tray. A spring is connected between the pressing frame and the second mounting plate. Second electric push rods are arranged at intervals at the bottom of the second mounting plate, and rollers are connected to the telescopic rods of the second electric push rods. The rollers are used to bend a part of the position of the preset heating tube on the baking tray, so as to fix the heating tube on the baking tray.

[0006] In addition, particularly preferably, the guiding mechanism includes a third electric push rod and a first guiding plate. Third electric push rods are symmetrically arranged on the top of the conveyor, and a first guiding plate is connected to the telescopic rod of the third electric push rod. The first guiding plate is used to guide the baking tray conveyed on the conveyor.

The second support frame is connected to the limiting block. A second hydraulic cylinder is installed on the third support frame, and the telescopic rod of the second hydraulic cylinder is connected to the second mounting plate.

[0008] In addition, particularly preferably, the blocking mechanism includes a sliding rod, a partition plate and a movable rod. A sliding rod is slidably arranged at the bottom of the limiting block. One end of the sliding rod facing the bottom edge of the limiting block is connected to the partition plate, and the partition plate is used to block the remaining heating tubes from dropping. A movable rod is rotatably arranged between one end of the sliding rod facing the center of the bottom of the limiting block and the supporting plate.

[0009] In addition, particularly preferably, it further includes a second guiding plate. Second guiding plates are symmetrically arranged on the side surface of the first mounting plate, and the second guiding plates are used to guide the baking tray below the first mounting plate.

[0010] In addition, it is particularly preferred that a guide rod is further included. The guide rods are arranged at intervals along the bottom edge of the limit block and are used to guide the heating tube during its fall.

Through the cooperation of the heating wire, the supporting plate, the blocking mechanism, the pressing frame, the spring and the roller, the present invention can automatically and accurately place the heating tube in the preset position, thus avoiding the problem of position deviation caused by manual placement. Moreover, the fully automated process from baking tray loading to heating tube placement and finally to crimping completion does not require manual intervention, which not only speeds up the production speed, but also reduces the labor cost, and can ensure the consistency of each installation process, reduce the errors caused by human factors, reduce the defective rate, and improve the stability of product quality.

[0014] 2. By setting the second guide plate, the present invention can guide the baking tray with the second guide plate, enabling the baking tray to automatically adjust its position by moving left and right, thus preventing the baking tray from shifting.

[0015] 3. By setting the pressing mechanism, the present invention can press the heating tube on the baking tray downward with the pressing rod, so that the heating tube is in the preset position of the baking tray, thus preventing the heating tube from shifting during the movement of the baking tray due to not being completely in the preset position of the baking tray, resulting in misalignment of the heating tube when pressing the heating tube subsequently.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment: An automatic baking tray heating tube press, refer to Figures 1-7As shown in the figure, it includes a conveyor 1; it also includes a rubber strip 2, a guiding mechanism, a supporting mechanism, a first mounting plate 5, a heating wire 6, a limiting block 7, a first electric push rod 8, a supporting plate 9, a blocking mechanism, a second mounting plate 11, a pressing frame 12, a spring 13, a second electric push rod 14 and a roller 15; Rubber strips 2 are evenly spaced on the conveyor belt of the conveyor 1, and the rubber strips 2 are used to drive the baking tray 101 to move, so as to convey the baking tray 101; A guiding mechanism for guiding the baking tray 101 is arranged on the conveyor 1; A supporting mechanism is arranged on the conveyor 1, and a first mounting plate 5 is arranged on the supporting mechanism; A heating wire 6 is arranged at the bottom of the first mounting plate 5, and the heating wire 6 is used to thermally melt the position of the preset heating tube 102 on the baking tray 101; A limiting block 7 for limiting the heating tube 102 is also arranged on the supporting mechanism; Four first electric push rods 8 are arranged at intervals at the bottom of the limiting block 7.

The telescopic rods of the remaining two first electric push rods 8 face backward, and a supporting plate 9 is also connected between the telescopic rods of these two first electric push rods 8. The supporting plate 9 is used to support the stacked heating tubes 102; A blocking mechanism is also arranged at the bottom of the limiting block 7. When the lowermost heating tube 102 falls, the blocking mechanism is used to block the remaining heating tubes 102 from falling; A second mounting plate 11 is also arranged on the supporting mechanism. Two pressing frames 12 are slidably arranged at the bottom of the second mounting plate 11, and the pressing frames 12 are used to press the heating tubes 102 on the baking tray 101; Three springs 13 are connected between the pressing frame 12 and the bottom of the second mounting plate 11; Second electric push rods 14 are arranged at intervals at the bottom of the second mounting plate 11; A roller 15 is connected to the telescopic rod of the second electric push rod 14; The roller 15 is used to bend a part of the thermally melted position of the preset heating tube 102 on the baking tray 101, so that the bent position limits the heating tube 102 on the baking tray 101, thereby fixing the heating tube 102 on the baking tray 101.

[0030] See Figure 2 As shown in the figure, the guiding mechanism includes a third electric push rod 301 and a first guiding plate 302; Four third electric push rods 301 are symmetrically arranged before and after at the top of the conveyor 1; A first guiding plate 302 is connected between the telescopic rods of the two front third electric push rods 301, and a first guiding plate 302 is also connected between the telescopic rods of the two rear third electric push rods 301. The first guiding plate 302 is used to guide the baking tray 101 conveyed on the conveyor 1.

[0031] See Figure 2As shown in the figure, the support mechanism includes a first support frame 401, a first hydraulic cylinder 402, a second support frame 403, a third support frame 404, and a second hydraulic cylinder 405. In the middle of the rear side of the top of the conveyor 1, there is a first support frame 401. On the upper side of the first support frame 401, a first hydraulic cylinder 402 is installed, and the telescopic rod of the first hydraulic cylinder 402 is connected to the first mounting plate 5. On the right side of the front side of the top of the conveyor 1, there is a second support frame 403, and the upper part of the rear side of the second support frame 403 is connected to the limit block 7. On the right side of the rear side of the top of the conveyor 1, there is a third support frame 404. The first support frame 401, the second support frame 403, and the third support frame 404 are distributed in sequence from left to right. On the upper side of the third support frame 404, a second hydraulic cylinder 405 is installed, and the telescopic rod of the second hydraulic cylinder 405 is connected to the second mounting plate 11.

[0032] See Figure 4 and Figure 5 As shown in the figure, the barrier mechanism includes a sliding rod 1001, a partition plate 1002, and a movable rod 1003. On the left and right sides of the bottom of the limit block 7, sliding rods 1001 are slidably arranged. At the mutually remote ends of the two sliding rods 1001, partition plates 1002 are connected respectively. The partition plates 1002 are used to block the remaining heating tubes 102 from falling. At the mutually close ends of the two sliding rods 1001, movable rods 1003 are rotatably connected respectively. The two movable rods 1003 are rotatably connected to the two supporting plates 9 respectively.

[0033] During use, first, according to the distance between the front and rear sides of the baking tray 101, then control the third electric push rod 301 to drive the first guide plate 302 to move, so as to adjust the distance between the two first guide plates 302 to make it adapt to the distance between the front and rear sides of the baking tray 101 (the distance between the two first guide plates 302 is slightly larger than the distance between the front and rear sides of the baking tray 101). After adjustment, then stack an appropriate amount of heating tubes 102 on the supporting plate 9, make the lowermost heating tube 102 contact the supporting plate 9, and limit the heating tubes 102 through the limit block 7 (as Figure 5 shown in the figure), and then place the baking tray 101 on the conveyor belt of the conveyor 1 in sequence, so that the baking tray 101 covers the rubber strip 2 (as Figure 2As shown, then the conveyor 1 is driven to move the rubber strip 2 on the conveyor belt, so that the rubber strip 2 drives the baking tray 101 to be conveyed to the right. When the baking tray 101 contacts the first guide plate 302, the first guide plate 302 will guide the baking tray 101, enabling the baking tray 101 to automatically adjust its position by moving back and forth, so that the baking tray 101 is on the same plane as the first mounting plate 5. When the baking tray 101 is conveyed to the right to be directly below the first mounting plate 5, the conveyor 1 will stop conveying the baking tray 101. Then, the first hydraulic cylinder 402 is driven to move the first mounting plate 5 and the heating wire 6 downward, so that the heating wire 6 approaches the baking tray 101, thereby melting the position of the preset heating tube 102 on the baking tray 101 through the heating wire 6, and thus softening the position of the preset heating tube 102 on the baking tray 101. After the softening treatment of the position of the preset heating tube 102 on the baking tray 101 is completed, the first hydraulic cylinder 402 is driven to move the first mounting plate 5 and the heating wire 6 upward to reset;

[0034] Then, the conveyor 1 continues to convey the baking tray 101 to move to the right until the baking tray 101 is directly below the limit block 7. Then the conveyor 1 will stop conveying the baking tray 101. Subsequently, the first electric push rod 8 is driven to move two supporting plates 9 toward the side close to each other, so that the supporting plates 9 gradually release the lowermost heating tube 102. At the same time, when the two supporting plates 9 move toward the side close to each other, the two supporting plates 9 will respectively push two partition plates 1002 toward the side away from each other through the movable rod 1003 and the sliding rod 1001, so that the two partition plates 1002 gradually extend into the space between the two lowermost heating tubes 102, so that the two partition plates 1002 support the remaining heating tubes 102. When the supporting plates 9 completely release the lowermost heating tube 102, the lowermost heating tube 102 will naturally fall downward to the preset position on the baking tray 101. Then, the first electric push rod 8 is driven to move the two supporting plates 9 toward the side away from each other to reset, so that the two supporting plates 9 respectively pull the two partition plates 1002 toward the side close to each other through the movable rod 1003 and the sliding rod 1001 to reset, so that the two partition plates 1002 gradually release the remaining heating tubes 102. When the partition plates 1002 complete releasing the remaining heating tubes 102, the remaining heating tubes 102 will naturally fall downward onto the supporting plates 9;

[0035] Next, the conveyor 1 continues to convey the baking tray 101 to move it to the right, causing the baking tray 101 to carry the heating tube 102 thereon and move to the right together until the baking tray 101 is directly below the second mounting plate 11. Then, the conveyor 1 stops conveying the baking tray 101. Subsequently, the second hydraulic cylinder 405 drives the second mounting plate 11, the pressing frame 12, the second electric push rod 14, and the roller 15 to move downward. When the pressing frame 12 contacts the heating tube 102 on the baking tray 101, the heating tube 102 will block the pressing frame 12. As the second mounting plate 11 continues to move downward, the spring 13 compresses. Affected by the elastic force of the spring 13, the spring 13 will apply a pressure to the pressing frame 12, causing the pressing frame 12 to press the heating tube 102 tightly onto the baking tray 101. After that, the second electric push rod 14 drives the roller 15 to move towards the side close to the heating tube 102. When the roller 15 contacts the preset position of the heating tube 102 on the baking tray 101, since the preset position of the heating tube 102 on the baking tray 101 has been softened in advance, therefore, the roller 15 will squeeze the contacted position on the baking tray 101 and cause the position to bend until the position is arc-shaped and pressed on the heating tube 102, thereby limiting the heating tube 102 at this position, thus fixing the heating tube 102 on the baking tray 101, and thus completing the crimping of the heating tube 102. Then, the second electric push rod 14 drives the roller 15 to move away from the heating tube 102 and reset. Then, the second hydraulic cylinder 405 drives the second mounting plate 11, the second electric push rod 14, and the roller 15 to move upward and reset. During this period, the spring 13 gradually returns to its original state. When the spring 13 is reset, the second mounting plate 11 will drive the pressing frame 12 to move upward and reset through the spring 13, separating the pressing frame 12 from the heating tube 102. Then, the conveyor 1 continues to convey the baking tray 101 to move to the right for discharging. In this way, the automatic crimping of the heating tube 102 onto the baking tray 101 can be realized, and then the above operations can be repeated.

[0036] See Figure 8 As shown, it further includes a second guide plate 16; the second guide plates 16 are symmetrically arranged on the left and right sides of the first mounting plate 5, and the second guide plates 16 are used to guide the baking tray 101 below the first mounting plate 5.

[0037] By setting the second guide plate 16, when the first mounting plate 5 moves downward, the first mounting plate 5 will drive the second guide plate 16 to move downward. When the second guide plate 16 contacts the baking tray 101, the second guide plate 16 will guide the baking tray 101 to automatically adjust its own position by moving left and right, thereby preventing the baking tray 101 from shifting in position; when the first mounting plate 5 moves upward and resets, the first mounting plate 5 will drive the second guide plate 16 to move upward and reset.

[0038] See Figure 9 and Figure 10As shown, it further includes a guide rod 17; guide rods 17 are arranged at intervals along the bottom edge of the limit block 7, and the guide rods 17 are used to guide the heating tube 102 during its fall.

[0039] When the lowermost heating tube 102 falls downward from around the limit block 7 and contacts the guide rod 17, the guide rod 17 can guide the falling heating tube 102, enabling the heating tube 102 to accurately land at the preset position on the baking tray 101, thereby preventing the heating tube 102 from shifting during the fall.

[0040] See Figure 8 and Figure 9 As shown, it further includes a limiting mechanism, and the limiting mechanism includes a fourth electric push rod 18 and a limiting frame 19; a fourth electric push rod 18 is arranged in the middle of the inner side of the limit block 7; a limiting frame 19 for limiting the heating tube 102 is slidably arranged on the top of the limit block 7, and the limiting frame 19 is connected to the telescopic rod of the fourth electric push rod 18.

[0041] By setting the limiting mechanism, when an appropriate amount of heating tubes 102 need to be stacked on the support plate 9, the fourth electric push rod 18 can be first used to drive the limiting frame 19 to move downward, so that the limiting frame 19 does not affect the operator's placement of the stacked heating tubes 102 on the support plate 9. Then, the operator can stack an appropriate amount of heating tubes 102 on the support plate 9. After the appropriate amount of heating tubes 102 are placed, the fourth electric push rod 18 is used to drive the limiting frame 19 to move upward and reset, so that the limiting frame 19 limits the stacked heating tubes 102 (as shown in Figure 8 ), thereby preventing the heating tubes 102 from falling due to excessive stacking.

[0042] See Figure 8 and Figure 11 As shown, it further includes a pressing mechanism, and the pressing mechanism includes a connecting frame 20 and a pressing rod 21; two connecting frames 20 are arranged on the right side at the top of the conveyor 1; two pressing rods 21 are connected between the middle parts on the upper sides of the two connecting frames 20, and the pressing rods 21 are used to press the heating tubes 102 placed on the baking tray 101.

[0043] By setting the pressing mechanism, during the conveyor 1 transporting the baking tray 101 to move rightward, causing the baking tray 101 to carry the heating tubes 102 thereon to move rightward together, when the heating tubes 102 on the baking tray 101 contact the pressing rods 21, the pressing rods 21 will press the heating tubes 102 on the baking tray 101 downward, so that the heating tubes 102 are within the preset position of the baking tray 101, thereby preventing the heating tubes 102 from not being completely within the preset position of the baking tray 101, resulting in the heating tubes 102 on the baking tray 101 shifting during the movement of the baking tray 101, and thus causing the heating tubes 102 to be misaligned when the heating tubes 102 are subsequently pressed.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
