Abstract
Description
Technical Field
[0001] This utility model belongs to the field of packaging equipment technology, specifically relating to an adjustable temperature-controlled heat sealing mold. Background Technology
[0002] In the modern food packaging industry, heat sealing technology is widely used in the packaging process of various foods, especially in the production of solid foods. Heat sealing technology melts and seals the packaging material by heating a specific area, ensuring the packaging is airtight and preventing external factors such as air, moisture, and contaminants from affecting product quality. For the production and packaging of solid compound seasoning powders, the heat sealing process not only needs to ensure the packaging is airtight but also requires controlling the heat sealing temperature of the packaging material to avoid affecting the quality and appearance of the seasoning powder.
[0003] A prior art patent, CN220164338U, describes a heat-sealing machine for packaging bags. This patent includes a base on which a heat-sealing mechanism for sealing the packaging bags is mounted. Two sets of transmission gears are rotatably mounted on the base, each set containing two gears. These two gears are distributed along the direction of bag movement and are located on either side of the heat-sealing mechanism. A rubber belt is fitted onto each of the two gears in each set. The two rubber belts abut against the two side walls of the packaging bag. The gear belts are located between the heat-sealing mechanism and the base. After the coffee is packaged, it is placed between the two rubber belts. The rubber belts rotate under the drive of the transmission gears, thereby... The device moves the packaging bag towards the heat-sealing mechanism. The rubber band abuts against the side wall of the bag, ensuring its stable movement. During heat sealing, the rubber band clamps the bag, ensuring the sealed opening is always in the same position. However, in practical use, the following shortcomings exist: While the device uses a cylinder as the drive, it lacks a guiding structure for the cylinder's movement. The cylinder output is prone to jamming and damage during long-term lifting and lowering. Furthermore, the heat-sealing head temperature is not adjustable, leading to incomplete sealing or overheating of the sealing material, affecting product quality.
[0004] Therefore, an adjustable temperature-controlled heat sealing mold is needed to solve the problems in the existing technology, such as the lack of cylinder stroke guidance, which easily leads to eccentric damage at the cylinder output end and the inability to adjust the temperature of the heat sealing head, thus affecting product quality.

[0025] The present invention will be further described below with reference to the embodiments.
[0026] Please see Figure 1-5 This utility model provides an adjustable temperature control heat sealing mold, including a base 1, a support platform 2 fixedly connected to the top of the base 1, two top plates 3 fixedly connected to the top of the support platform 2, a conveyor belt 4 installed on the top of the two top plates 3, a plurality of evenly distributed limiting mechanisms 5 provided on the surface of the conveyor belt 4, a support plate 6 fixedly connected to the top of each of the two top plates 3, and a heat sealing mechanism 7 provided on the top of the two support plates 6.
[0027] Further as Figure 1 and Figure 2 As shown, it is worth noting that the base 1 has multiple mounting and positioning holes that run through it. These holes ensure that the device can be accurately positioned and fixed during assembly, reducing installation errors and improving the stability and accuracy of the equipment.
[0028] Further as Figure 3 As shown, it is worth noting that the limiting mechanism 5 includes a limiting seat 501 fixedly connected to the outer wall of the conveyor belt 4. Two clamping plates 502 are rotatably connected to the top of the limiting seat 501. Torsion springs 503 are fixedly installed between the two clamping plates 502 and the limiting seat 501. By setting the limiting mechanism 5, under the action of the torsion springs 503, the two clamping plates 502 can stably clamp and limit the solid compound seasoning powder packaging bag, preventing the packaging bag from shifting during heat sealing and ensuring the consistency and stability of the heat sealing effect.
[0029] Further as Figure 3 As shown, it is worth noting that anti-slip sleeves are fixedly connected to the surfaces of both clamps 502. The anti-slip sleeves further increase the friction between the clamps 502 and the solid compound seasoning powder packaging bag, so that the solid compound seasoning powder packaging bag will not deviate during the movement of following the conveyor belt 4.
[0030] As can be seen from the above working process: by setting the limiting mechanism 5, under the action of the torsion spring 503, the two clamping plates 502 can stably clamp and limit the solid compound seasoning powder packaging bag, preventing the packaging bag from shifting during heat sealing, and ensuring the consistency and stability of the heat sealing effect.
[0031] Further as Figure 4 and Figure 5 As shown, it is worth noting that the heat sealing mechanism 7 includes a frame 701 fixedly connected to the top of the two support plates 6. Mounting seats 702 are fixedly connected to the inner walls of both the front and rear ends of the frame 701. A sliding rod 703 is fixedly connected between every two corresponding mounting seats 702. A cylinder 704 is fixedly connected to the rear end of the frame 701. A connecting block 705 is fixedly connected to the output end of the cylinder 704. A first sliding plate 706 is fixedly connected to the front end of the connecting block 705. Two guide rods 707 are slidably connected to the inner wall of the first sliding plate 706. Springs 708 are sleeved on the outer walls of both guide rods 707. A second sliding plate 709 is fixedly connected to the front ends of the two guide rods 707. A third sliding plate 710 is slidably connected to the outer walls of the two sliding rods 703 near the front end. L-shaped brackets 711 are fixedly connected to the bottom of both the second and third sliding plates 710. Heat sealing heads 712 are fixedly connected to the bottom of both L-shaped brackets 711. The outer sides of both heat sealing heads 712 are fixedly... A heat-sealing mechanism 7 is provided. A temperature controller 713 is connected to the inner walls of both sides of the frame 701, and rotating plates 714 are rotatably connected to the inner walls of both sides. A first connecting rod 715 is rotatably connected to the rear ends of both rotating plates 714, and a first linkage plate 716 is rotatably connected to the rear ends of both first connecting rods 715. A second connecting rod 717 is rotatably connected to the front ends of both rotating plates 714, and a second linkage plate 718 is rotatably connected to the front ends of both second connecting rods 717. Through this heat-sealing mechanism 7, two sliding rods 703 limit and guide the drive trajectory of the cylinder 704. Simultaneously, the guide rod 707 and spring 708 work together to absorb the connection error between the cylinder 704 and the connecting block 705, further protecting the operation of the cylinder 704, preventing damage to the cylinder's stroke, and extending the device's service life. Furthermore, the guide rod 707 and spring 708 work together to buffer the heat-sealing process, preventing the solid compound seasoning powder packaging bag from being stretched and deformed during heat sealing.
[0032] Further as Figure 4 and Figure 5 As shown, it is worth noting that both the first slide plate 706 and the second slide plate 709 are slidably connected to the outer wall of the slide rod 703. The slide rod 703 plays a role in limiting and guiding the movement of the first slide plate 706 and the second slide plate 709, and cooperates with the cylinder 704 to prevent the cylinder 704 from being damaged during its stroke.
[0033] Further as Figure 4 and Figure 5As shown, it is worth noting that the spring 708 is fixedly connected between the bottom of the first slide plate 706 and the top of the second slide plate 709. The guide rod 707 and the spring 708 work together to buffer the heat sealing process and prevent the solid compound seasoning powder packaging bag from being stretched and deformed during heat sealing.
[0034] Further as Figure 4 and Figure 5 As shown, it is worth noting that the two heat sealing heads 712 are symmetrically designed, and each of the two heat sealing heads 712 is equipped with an electric heating wire corresponding to the temperature controller 713. The temperature controller 713 can monitor temperature changes in real time and adjust them through the electric heating wire to ensure that the temperature is always within the ideal range, thus avoiding poor sealing caused by excessively high or low temperatures.
[0035] Further as Figure 4 and Figure 5 As shown, the first linkage plate 716 is fixedly connected to the outside of the first slide plate 706, and the second linkage plate 718 is fixedly connected to the outside of the third slide plate 710, ensuring that the first slide plate 706 and the third slide plate 710 move towards each other simultaneously to complete the heat sealing work.
[0036] The working process of this solution is as follows: In actual use, the solid compound seasoning powder packaging bag to be sealed is placed between two clamping plates 502. Under the action of the torsion spring 503, the two clamping plates 502 can stably clamp and limit the solid compound seasoning powder packaging bag. The conveyor belt 4 is opened to transport the packaging bag. When it moves between the two heat sealing heads 712, the conveyor belt 4 stops. The cylinder 704 is opened to drive the connecting block 705 to move, so that the first sliding plate 706 and the second sliding plate 709 move forward. Under the action of the rotating plate 714, the first linkage plate 716 drives the second linkage plate 718 to move relative to each other, so that the two heat sealing heads 712 move inward at the same time to squeeze and heat seal the solid compound seasoning powder packaging bag. After the heat sealing is completed, the cylinder 704 retracts, the conveyor belt 4 is opened to drive the sealed packaging bag to move, and the device repeats the sealing cycle.
[0037] In summary: By setting the limiting mechanism 5, under the action of the torsion spring 503, the two clamping plates 502 can stably clamp and limit the solid compound seasoning powder packaging bag, preventing the packaging bag from shifting during heat sealing and ensuring the consistency and stability of the heat sealing effect; by setting the heat sealing mechanism 7, the two sliding rods 703 play a role in limiting and guiding the driving trajectory of the cylinder 704. At the same time, the guide rod 707 and the spring 708 cooperate to absorb the connection error between the cylinder 704 and the connecting block 705, further protecting the operation of the cylinder 704, preventing the cylinder 704 from being damaged during stroke, and extending the service life of the device; at the same time, the guide rod 707 and the spring 708 cooperate to buffer the heat sealing process, preventing the solid compound seasoning powder packaging bag from being pulled and deformed during heat sealing.
[0038] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
