Description

Technical Field

[0001] This utility model relates to the technical field of condiment processing equipment, and in particular to a preheating device for a condiment bottle labeling production line. Background Technology

[0002] Bottled condiments require labeling on the side of the bottle. To improve labeling results, the bottle is usually preheated to around 60°C for a period of time before labeling. A common method is to use a heating hood, where a conveyor belt continuously preheats the product, improving labeling efficiency. However, this heating hood still has the following problems: 1. Heating covers are usually of a fixed size and cannot be adjusted according to the size of the bottle. They can only be processed within the opening range of the heating cover, resulting in poor applicability. 2. The temperature of the heating cover is usually not self-controllable. It uses electric heating wire or electric heating plate for continuous heating, and the temperature is easy to be higher than the set value. The excessive temperature can affect the labeling process and cause labeling errors, which will require relabeling. Moreover, the bottles with incorrect labels after heating are difficult to clean. Utility Model Content

[0003] This utility model provides a preheating device for a condiment bottle labeling production line, which aims to solve the problems mentioned above, such as the fixed size and poor applicability of the existing preheating cover before labeling, and the inability to automatically control the temperature of the heating cover, which leads to labeling failure and further makes it difficult to clean the bottles after labeling failure.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A preheating device for a condiment bottle labeling production line includes a telescopic cover mounted on a conveyor belt. The telescopic cover has a variable height due to a telescopic component. Openings are provided at both the front and rear ends of the telescopic cover along the conveying direction. The conveyor belt passes through the openings of the telescopic cover, and the height of the openings changes synchronously with the height of the telescopic component. Several heating components are provided inside the telescopic cover. A temperature sensor is provided at the top of the telescopic cover to sense the temperature inside the cover. Both the temperature sensor and the heating components are electrically connected to a control component, and the temperature sensor and the heating components work together in a coordinated manner through the control component.

[0005] Preferably, the telescopic cover includes two lower limiting plates and an upper cover with the opening facing downwards; Two lower limit plates are arranged opposite each other on both sides of the conveyor belt, and the lower limit plates are symmetrical about the conveyor belt. The lower limit plates are arranged vertically and parallel to the conveying direction. The lower limit plates and the conveyor belt cooperate to form a heating groove. The upper cover is sleeved on the top of the heating groove to form a cap. The upper cover and the heating groove form a limiting sliding cooperation in the vertical direction. The two sides of the cover opening of the upper cover form a telescopic support cooperation with the two sides of the conveyor belt through several telescopic components.

[0006] More preferably, the opening includes an upper part and a lower part. The gap between the corresponding ends of the two lower limiting plates forms the lower part, and the upper part is located at the position corresponding to the lower part of the upper cover. When the upper cover is fitted onto the heating groove formed by the lower limiting plate, the upper part and the lower part partially overlap in the vertical direction to form an opening.

[0007] Furthermore, the width of the upper part is the same as the width of the lower part, and when the upper part and the lower part partially overlap in the vertical direction, the width of the upper part is aligned with the width of the lower part.

[0008] Furthermore, the width of the opening is not less than the width of the conveyor belt.

[0009] More preferably, the lower limiting plate is provided with an installation groove on the side near the heating tank. The installation groove and the lower limiting plate cooperate to form a U-shaped structure. The heating components are arranged at equal intervals in the installation groove along the conveying direction. The temperature sensor is located on the top of the upper cover, and the sensing end of the temperature sensor forms a sensing cooperation with the top of the heating tank.

[0010] Furthermore, the heating component is a plate-shaped infrared radiant heater. The infrared radiant heater is located in the mounting groove and does not collide with the bottle body. Each of the four corners of the infrared radiant heater is provided with an L-shaped mounting piece. The L-shaped mounting piece is fixedly installed to the bottom of the mounting groove by fasteners, and the infrared radiant heater is supported by the L-shaped mounting piece and the bottom of the mounting groove to avoid direct contact.

[0011] More preferably, the bottom of the lower limiting plate on the side away from the heating tank is provided with several horizontal extension blocks at equal intervals along the conveying direction. The horizontal extension blocks extend horizontally towards the side away from the conveyor belt, and the horizontal extension blocks are fixedly engaged with both sides of the conveyor belt by fasteners.

[0012] More preferably, the upper cover has several telescopic components on both sides of the cover opening along the conveying direction. Each telescopic component includes a vertically arranged hydraulic cylinder. The output end of the hydraulic cylinder is provided with an output end mounting seat. The output end mounting seat is fixedly engaged with the bottom of both sides of the cover opening of the upper cover by fasteners. The fixed end of the hydraulic cylinder is provided with a fixed end mounting seat. The fixed end mounting seat is fixedly engaged with both sides of the conveyor belt by fasteners.

[0013] More preferably, the control component includes a housing located on one side of the conveyor belt, an industrial PLC controller inside the housing, and a display screen and an operation panel on the outside of the housing.

[0014] The beneficial effects of this utility model are: (1) By moving the upper cover through the telescopic component, the relative position of the upper cover and the lower limit plate is changed, thereby changing the height of the entire telescopic cover. The overlapping part of the opening at the upper and lower parts changes synchronously with the change of the height of the telescopic cover. When the height of the telescopic cover increases, the overlapping part of the upper and lower parts in the vertical direction decreases, and the opening becomes higher. Conversely, when the height of the telescopic cover decreases, the opening also becomes lower. Thus, the opening can be adjusted and the height of the cover can also be adjusted, improving applicability. It can preheat various height bottles within the range of change, covering almost all commonly used bottles. (2) By limiting the width of the upper part to be aligned with the width of the lower part when the upper and lower parts partially overlap in the vertical direction, and ensuring that the width of the opening is not less than the width of the conveyor belt, the opening itself is sufficient for use. Usually, the width of the bottle body will not be greater than the width of the conveyor belt, otherwise there may be problems with transportation. Therefore, ensuring that the width of the opening is aligned and not less than the width of the conveyor belt ensures the neatness when the opening changes and avoids the bottle body from bumping. On the other hand, it ensures that the width of the opening meets the needs of the conveyor belt to process the bottle body, making it easy for the bottle body to enter smoothly. (3) The temperature inside the telescopic cover is monitored in real time by a temperature sensor. The temperature range can be set by the control component and the operating power of the heating component can be automatically controlled to achieve automatic temperature control. When the temperature is detected to be higher than the set maximum temperature, the power of the heating component is reduced by the control component to cool down until the temperature is lower than the set maximum temperature and the power is maintained. When the temperature is detected to be lower than the set minimum temperature, the power of the heating component is increased by the control component to heat up until the temperature is higher than the set minimum temperature and the power is maintained to keep the temperature constant within the set range. (4) The device is easy to disassemble and install, and easy to move and maintain. Attached Figure Description

[0016] The embodiments will be further described below with reference to the accompanying drawings.

[0017] like Figures 1-4 As shown in the preferred embodiment 1, the preheating device for a condiment bottle labeling production line includes a telescopic cover 2 mounted on a conveyor belt 1. The telescopic cover 2 has a variable height due to a telescopic component 3. Openings 5 ​​are provided at both ends of the telescopic cover 2 along the conveying direction. The conveyor belt 1 passes through the telescopic cover 2 along the openings 5. The height of the openings 5 ​​changes synchronously with the height of the telescopic component 3. Several heating components 4 are provided inside the telescopic cover 2. A temperature sensor 6 is provided at the top of the telescopic cover 2 to sense the temperature inside the cover. The temperature sensor 6 and the heating components 4 are electrically connected to a control component 7, and the temperature sensor 6 and the heating components 4 are linked together through the control component 7.

[0018] As a preferred embodiment 2, the telescopic cover 2 includes two lower limiting plates 22 and an upper cover 21 with the opening facing downward; Two lower limit plates 22 are arranged opposite each other on both sides of the conveyor belt 1, and the lower limit plates 22 are symmetrical about the conveyor belt 1. The lower limit plates 22 are both arranged vertically and parallel to the conveying direction. The lower limit plates 22 and the conveyor belt 1 cooperate to form a heating groove. The upper cover 21 is sleeved on the top of the heating groove to form a cap. The upper cover 21 forms a limiting sliding cooperation with the heating groove in the vertical direction. The two sides of the cover opening of the upper cover 21 are connected to the two sides of the conveyor belt 1 through several telescopic components 3 to form a telescopic support cooperation.

[0019] The opening 5 includes an upper part 51 and a lower part 52. The gap between the corresponding ends of the two lower limiting plates 22 forms the lower part 52. The upper part 51 is located at the position corresponding to the upper cover 21 and the lower part 52. When the upper cover 21 is sleeved on the heating groove formed by the lower limiting plate 22, the upper part 51 and the lower part 52 partially overlap in the vertical direction to form the opening 5.

[0020] The bottle body moves along the conveyor belt 1 through the opening 5 into the telescopic cover 2. The heating component 4 creates a constant temperature environment within the telescopic cover 2, which is preheated by hot air and radiation. When all the telescopic components 3 are raised, the upper cover 21 is raised, thereby increasing the height of the opening 5. When all the telescopic components 3 are lowered, the upper cover 21 is lowered, thereby decreasing the height of the opening 5, thus achieving height control.

[0021] During the process, the upper cover 21 is always fitted onto the top of the heating tank and does not detach from the heating tank, ensuring the integrity of the cover and minimizing heat leakage from the heating tank to ensure the preheating effect.

[0022] In a preferred embodiment 3, the width of the upper part 51 is the same as the width of the lower part 52. When the upper part 51 and the lower part 52 partially overlap in the vertical direction, the width of the upper part 51 is aligned with the width of the lower part 52. This ensures that the width remains aligned when the height of the opening 5 changes, without affecting the normal entry of the bottle.

[0023] In a preferred embodiment 4, the width of the opening 5 is not less than the width of the conveyor belt 1. This ensures that the width of the opening 5 basically meets the width requirements of the bottle body transported by the conveyor belt 1 during normal transport. The width of the bottle body transported by the conveyor belt 1 is generally less than the width of the conveyor belt 1, so as not to conflict with the transport of the bottle body.

[0024] As a preferred embodiment 5, the lower limiting plate 22 is provided with an installation groove 221 on the side near the heating tank. The installation groove 221 and the lower limiting plate 22 cooperate to form a U-shaped structure. The heating components 4 are equally spaced in the installation groove 221 along the conveying direction. The temperature sensor 6 is located on the top of the upper cover 21, and the sensing end of the temperature sensor 6 forms a sensing cooperation with the top of the heating tank.

[0025] The heating component 4 is a plate-shaped infrared radiant heater 41. The infrared radiant heater 41 is located in the mounting groove 221 and does not collide with the bottle body. Each of the four corners of the infrared radiant heater 41 is provided with an L-shaped mounting piece 42. The L-shaped mounting piece 42 is fixedly installed to the bottom of the mounting groove 221 by fasteners. The infrared radiant heater 41 is supported by the L-shaped mounting piece 42 and the bottom of the mounting groove 221 to avoid direct contact.

[0026] The plate-shaped infrared radiant heater 41 can be used to preheat the heating by utilizing the thermal environment inside the cover and thermal radiation, ensuring the preheating effect. The temperature can be controlled by controlling the heating power. The top of one right-angled side of the L-mount 42 is fixedly engaged with the infrared radiant heater 41, and the other right-angled side of the L-mount 42 is fixedly installed to the bottom of the mounting groove 221 by fasteners, avoiding direct contact between the heating plate and the lower limit plate 22. It also allows the infrared radiant heater 41 to be closer to the inside of the heating groove without colliding with the bottle body when it is located in the mounting groove 221, making it convenient for installation and disassembly.

[0027] In a preferred embodiment 6, the bottom of the lower limiting plate 22 on the side away from the heating tank is provided with a plurality of horizontal extension blocks 222 at equal intervals along the conveying direction. The horizontal extension blocks 222 all extend horizontally towards the side away from the conveyor belt 1, and are fixedly engaged with both sides of the conveyor belt 1 by fasteners. This ensures the effective installation of the lower limiting plate 22 and facilitates installation and disassembly.

[0028] As a preferred embodiment 7, the upper cover 21 has several telescopic components 3 on both sides of the cover opening along the conveying direction. Each telescopic component 3 includes a vertically arranged hydraulic cylinder 31. The output end of the hydraulic cylinder 31 is provided with an output end mounting seat 32. The output end mounting seat 32 is fixedly engaged with the bottom of both sides of the cover opening of the upper cover 21 by fasteners. The fixed end of the hydraulic cylinder 31 is provided with a fixed end mounting seat 33. The fixed end mounting seat 33 is fixedly engaged with both sides of the conveyor belt 1 by fasteners.

[0029] The telescopic components 3 are of the same length and operate synchronously in the same state to ensure the stability of the support. The hydraulic cylinder 31 provides driving force to raise or lower the upper cover 21, thereby realizing the height change of the opening 5. The output end mounting seat 32 and the fixed end mounting seat 33 ensure installation stability while facilitating disassembly.

[0030] The hydraulic cylinder 31 can be replaced by a similar telescopic structure, such as a pneumatic cylinder, an electric cylinder, or a telescopic rod.

[0031] As a preferred embodiment 8, the control component 7 includes a housing 71 located on one side of the conveyor belt 1, an industrial PLC controller is installed inside the housing 71, and a display screen 72 and an operation panel 73 are installed on the outside of the housing 71.

[0032] Display screen 72 is used to display parameters such as monitored temperature and set temperature range; The operation panel 73 is used to set parameters such as the temperature range. The operation panel 73 is also used to control the lifting and lowering of the hydraulic cylinder 31. The control switch of the power end of the hydraulic cylinder 31 is electrically connected to the operation panel 73 through the controller. The lifting and lowering can be controlled through the operation panel 73. The industrial PLC controller is used to achieve automatic control. When the temperature sensor 6 detects that the temperature is higher than the set maximum temperature, the controller reduces the power of the heating component 4 to cool down the temperature until it is lower than the set maximum temperature, and then maintains the power. When the temperature sensor 6 detects that the temperature is lower than the set minimum temperature, the controller increases the power of the heating component 4 to heat up the temperature until it is higher than the set minimum temperature, and then maintains the power to keep the temperature constant within the set range.

[0033] As a preferred embodiment 9, the upper cover 21 and the lower limit plate 22 can be made of lightweight alloy material, which is lightweight and easy to install and move. The surfaces of the upper cover 21 and the lower limit plate 22 are insulated with heat-insulating coating. On the one hand, this prevents the outer surface of the upper cover 21 and the lower limit plate 22 from getting too hot during preheating, so that the staff will not be burned by accidental contact. On the other hand, it gives the inside of the cover a certain heat preservation effect, ensuring the efficiency and stability of preheating.

[0034] As a preferred embodiment 10, the preheating temperature can be set to 60±5℃.

[0035] The working principle of this utility model: The upper cover 21 is moved by the telescopic component 3, changing the relative position of the upper cover 21 and the lower limit plate 22, thereby changing the height of the entire telescopic cover 2. The overlapping part of the upper part 51 and the lower part 52 of the opening 5 changes synchronously with the change of the height of the telescopic cover 2. When the height of the telescopic cover 2 increases, the overlapping part of the upper part 51 and the lower part 52 in the vertical direction decreases, and the opening 5 increases. Conversely, when the height of the telescopic cover 2 decreases, the opening 5 also decreases. Thus, the opening 5 can be adjusted, and the height of the cover can also be adjusted, improving applicability. It can preheat bottles of various heights within the range of change, covering almost all commonly used bottles. By restricting the width of the upper part 51 to be aligned with the width of the lower part 52 when the upper part 51 and the lower part 52 partially overlap in the vertical direction, and ensuring that the width of the opening 5 is not less than the width of the conveyor belt 1, the opening and closing degree of the opening 5 itself is sufficient for use. Usually, the width of the bottle body will not be greater than the width of the conveyor belt, otherwise there may be problems with transportation. Therefore, ensuring that the width of the opening 5 is aligned and not less than the width of the conveyor belt 1 ensures the neatness when the opening 5 changes, avoids the bottle body from bumping, and ensures that the width of the opening 5 meets the needs of the conveyor belt 1 to process the bottle body, so that the bottle body can enter smoothly. Temperature sensor 6 monitors the temperature inside telescopic cover 2 in real time. Control component 7 sets the temperature range and automatically controls the operating power of heating component 4 to achieve automatic temperature control. When the detected temperature is higher than the set maximum temperature, control component 7 reduces the power of heating component 4 to cool down until the temperature is lower than the set maximum temperature, and then maintains that power. When the detected temperature is lower than the set minimum temperature, control component 7 increases the power of heating component 4 to heat up until the temperature is higher than the set minimum temperature, and then maintains that power to keep the temperature constant within the set range.
