Description

Technical Field

[0001] This patent belongs to the field of tobacco equipment technology, specifically relating to an automatic balancing hot pressing device. Background Technology

[0002] Hot pressing is a process that achieves bonding and sealing between two materials. It is often used in products that need to be stored for a long time. For example, the flavor carrier unit used in heated cigarettes uses hot pressing to seal and preserve the flavorings inside.

Among them, hot pressing temperature and application time are two factors that are easy to achieve precisely. However, it is more difficult to control the pressure applied to the hot pressing surface to be uniform, which affects the hot pressing effect. Utility Model Content

[0030] Furthermore, a pressure transmission shaft is connected below the drive unit, and the pressure transmission shaft can extend or retract axially to connect to the sliding bracket.

[0031] The drive unit includes a cylinder.

[0032] The hot press block is equipped with a heating element.

[0033] The heating element is connected to the power source via heating wires.

[0034] The hot press block is also equipped with a thermal resistor.

[0035] The resistance temperature detector (RTD) can be connected to a control device and used to control the temperature range of the hot press block.

[0070] like Figure 1-4 As shown, the automatic pressure balancing hot pressing device provided by this patent mainly consists of a hot pressing block 40, a cylinder 10 (i.e., a driving device), a T-shaped bracket 20 (i.e., a sliding bracket), a hot pressing connecting block 30, a heating tube 43, a thermal resistor 42, a transverse pressure balancing spring 60, a longitudinal pressure balancing spring 50, and a guide rail 70.

[0071] A pressure transmission shaft 11 is connected below the cylinder 10. The pressure transmission shaft 11 can extend or retract along the axial direction to connect to the T-shaped bracket 20.

[0072] The T-shaped bracket 20 may include a vertical bracket 21 and a horizontal bracket 22 that are fixedly connected. The vertical bracket 21 is mounted on the guide rail 70 for axial sliding, and the horizontal bracket 22 is mounted between the cylinder 10 and the hot-pressing connecting block 30 so that the hot-pressing connecting block 30 drives the hot-pressing block 40 downward for hot-pressing sealing.

[0073] The hot-pressed connecting block 30 is equipped with a transverse pressure balance spring 60 and a longitudinal pressure spring.

[0074] The pressure balancing function of the hot press block 40 is achieved by the transverse pressure balancing spring 60 and the longitudinal pressure spring. The cylinder 10 drives the T-shaped bracket 20 to move downward. The longitudinal pressure spring cooperates between the T-shaped bracket 20 and the hot press block 40 connecting block, so that the longitudinal pressure is balanced.

[0075] The driving force provided by cylinder 10 continues to be transmitted downward to the connecting block of hot pressing block 40. A lateral pressure spring is fitted between the connecting block of hot pressing block 40 and hot pressing block 40 to balance the lateral pressure.

[0076] At this point, the force generated by cylinder 10 is transmitted to hot pressing block 40 through T-shaped bracket 20 and hot pressing connecting block 30. The lateral pressure balancing spring 60 and longitudinal pressure balancing spring 50 balance the lateral and longitudinal pressures, respectively. Specifically, the longitudinal pressure balancing spring 50 and the lateral pressure balancing spring 60 are arranged with lateral displacement; that is, the longitudinal pressure balancing spring 50 is positioned in the first axial direction, and the lateral pressure balancing spring 60 is positioned in the second axial direction. The first and second axial directions are arranged at an angle, so that the force is balanced in the transmission directions of the first and second axial directions, achieving longitudinal and lateral pressure balance. Ultimately, the thermal pressure exerted by hot pressing block 40 on the surface to be hot-pressed is balanced.

[0077] The longitudinal pressure balance spring 50 and the transverse pressure balance spring 60 are arranged in layers along the force axis of the cylinder 10. The hot-pressed connecting block 30 includes a longitudinal balance block 31 and a transverse balance block 32. The longitudinal pressure balance spring 50 is disposed above the transverse pressure balance spring 60. The longitudinal balance block 31 is connected to the horizontal support 22 with a gap through the longitudinal pressure balance spring 50. The transverse balance block 32 is connected to the longitudinal balance block 31 with a gap through the transverse pressure balance spring 60.

[0078] One end of the longitudinal pressure balancing spring 50 is connected to the horizontal bracket 22, and the other end is connected to the longitudinal balance block 31. The longitudinal balance block 31 is provided with a longitudinal spring fixing groove 311 for fixing the longitudinal pressure balancing spring 50. Preferably, at least 2 / 3 of the length of the longitudinal pressure balancing spring 50 is accommodated and fixed in the longitudinal spring fixing groove 311 to prevent the longitudinal pressure balancing spring 50 from displacing from the direction of the force of the cylinder 10.

[0079] One end of the lateral pressure balancing spring 60 is connected to the longitudinal balance block 31, and the other end is connected to the lateral balance block 32. The lateral balance block 32 is provided with a lateral spring fixing groove 321 for fixing the lateral pressure balancing spring 60. Preferably, at least 2 / 3 of the length of the lateral pressure balancing spring 60 is accommodated and fixed in the lateral spring fixing groove 321 to prevent the lateral pressure balancing spring 60 from displacing from the direction of the force applied by the cylinder 10.

[0080] The longitudinal balance block 31 can be configured as an inverted U-shaped structure, and the longitudinal balance block 31 surrounds the transverse balance block 32 on at least three sides. The cylinder 10 drives the longitudinal balance block 31 and the transverse balance block 32 to push the hot pressing block 40 downward for hot pressing process through the horizontal support 22.

[0081] Both longitudinal pressure balance spring 50 and transverse pressure balance spring 60 can be provided with at least 2.

[0082] The number of longitudinal spring fixing slots 311 corresponds to the number of longitudinal pressure balance springs 50;

[0083] The number of transverse spring fixing slots 321 corresponds to the number of transverse pressure balance springs 60.

[0084] In the above embodiment, the longitudinal pressure balance spring 50 is arranged in parallel along the first axial direction.

[0085] The adjacent lateral pressure balancing springs 60 are arranged in parallel along the second axis.

[0086] Preferably, the arrangement direction of the lateral pressure balance spring 60 (i.e., the second axis) is perpendicular to the arrangement direction of the longitudinal pressure balance spring 50 (i.e., the first axis).

[0087] Specifically, the longitudinal pressure balancing spring 50 is positioned close to the pressure transmission shaft 11.

[0088] Specifically, the transverse pressure balance springs 60 are arranged on the vertical line between adjacent longitudinal pressure balance springs 50, and preferably at least two are arranged.

[0089] The hot press block 40 can provide a balanced pressure on the surface to be hot-pressed.

[0090] The selection of the heating tube 43 and the thermal resistor 42 of the hot press block 40 is determined according to the required temperature.

[0091] The transverse spring fixing groove 321 and the longitudinal balance spring model and specifications need to be compatible with cylinder model 10.

[0092] The cylinder model 10 is determined by the pressure required.

[0093] It should be noted that the hot press block 40 can be the direct component for hot pressing the substrate layer and the wrapping layer of the fragrance carrier unit. The control device controls the cylinder 10 to move the hot press block 40 directly downward and press it onto the fragrance carrier unit so that the wrapping layer and the substrate layer of the fragrance carrier unit are encapsulated together.

[0094] The hot press block 40 is also provided with a slot for mounting a thermal resistor 42. The thermal resistor 42 can be connected to a control device and used to control the temperature range of the hot press block 40 so that the temperature of the hot press block 40 is 180-200℃.

[0095] It should be noted that the temperature range of the hot press block 40 is controlled by the thermal resistor 42 built into the hot press block 40. Within the set temperature range, the substrate layer and the wrapping layer of the fragrance carrier unit can achieve good encapsulation and sealing.

[0096] The hot press block 40 is equipped with a heating tube 43, which is connected to a power source via a heating wire 41. The power source can be connected to a control device. It is understood that the heating state of the heating tube 43 is controlled by the control device. After being heated, the heating tube 43 further transfers heat to the hot press block 40, thereby achieving the encapsulation of the fragrance carrier unit through the hot press block 40.

[0097] In the above embodiment, the inner diameter of the heating tube 43 is 10mm and the length of the heating tube 43 is 70mm.

[0098] It should be noted that the heating element 43 is made of stainless steel. This is how it is set in this embodiment. However, in real life, there are no restrictions on the material, specifications, quantity, or installation method of the heating element 43, as long as the above-mentioned technical effects can be achieved.

[0099] The function achieved by this patent is:

[0100] 1. The hot press block 40 can provide accurate pressure time and hot press temperature;

[0101] 2. Under the action of the transverse pressure balance spring 60 and the longitudinal pressure balance spring 50, the cylinder 10 drives the hot pressing block 40 to move downward, and the hot pressing block 40 can provide uniform pressure to the surface to be hot-pressed.

[0102] The automatic balancing hot-pressing device of this patent can typically be used in the hot-pressing preparation of flavor carrier units. When the flavor carrier unit needs to be hot-pressed, the control device (or manually) controls the cylinder 10 to operate. The pressure transmission shaft 11, as the output end of the cylinder 10, presses the horizontal support 22 downward. At this time, the vertical support 21 can slide downward on the guide rail 70. The force is transmitted to the longitudinal balance block 31 through the longitudinal pressure balance spring 50, and this force continues to be transmitted to the transverse balance block 32 through the transverse pressure balance spring 60, thereby achieving longitudinal and transverse pressure balance. This balancing force is also further transmitted to the hot-pressing block 40, causing the wrapping layer of the flavor carrier unit to be hot-pressed together with the substrate layer. When the cigarette is heated and smoked, the hot-pressed fixing structure between the wrapping layer and the substrate layer can be broken under the action of high-temperature smoke, releasing the flavoring and fragrance inside the substrate layer.
