Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tea production, in particular, relates to a tea brick production equipment. BACKGROUND

[0002] The information provided in this section is for the purpose of generally presenting the background of the application. The work of the presently named inventors, to the extent the descriptions are concerned therewith, and the descriptions of certain aspects of the description as set forth in this section are not necessarily prior art to the present application. Accordingly, explicit recognition of such descriptions as prior art against the present application should not be inferred or implied from discussing or referring to such material in this section.

[0003] In the field of tea production, tea leaves are pressed into tea bricks, which can reduce the volume and facilitate transportation. Later, it was found that after tea leaves are formed into tea bricks under high pressure, the contact between tea leaves and air is effectively reduced, so that the composition of tea leaves is transformed through fermentation. After a slow transformation time, the taste of tea leaves becomes better, and the storage time of tea leaves is longer.

[0004] After the tea bricks are pressed, they cannot be directly removed from the mold, otherwise the tea bricks that have not yet solidified will be damaged, and the tea bricks will become loose due to their own rebound. Therefore, cooling is usually required after pressing to eliminate the internal stress of the tea bricks. During this process, the tea bricks need to be continuously pressed to reduce the rebound deformation of the tea bricks and cause quality reduction. For example, a tea brick continuous pressing machine disclosed in Chinese patent CN103264517A can continuously press tea brick blanks to meet the demand of large-scale production.

[0005] However, the existing tea brick mold needs complicated procedures to achieve the limiting and locking of the tea brick mold during the cooling stage to achieve continuous pressing of the tea bricks. For example, manual tightening of multiple point bolts is used to lock the pressing cover to maintain the pressing of the tea bricks. This not only has high labor intensity, but also has complicated operation and low efficiency, which is not conducive to the rapid disassembly and recycling of the tea brick mold, and thus the production efficiency is difficult to further improve.

[0006] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present application, and therefore can include information that does not constitute prior art known to those skilled in the art. SUMMARY

DETAILED DESCRIPTION

[0035] The embodiments of the present application are described in detail below with reference to the accompanying drawings, but the present application can be implemented in various different ways as defined and covered by the following.

[0036] A tea brick production equipment includes a pressing mechanism, and the tea brick production equipment further includes:

[0037] The tea brick mold 100 includes a base 101, a mold body 102, a gland 103, and a limiting piece 104. The mold body 102 is placed on the base 101 and encloses the base 101 to form a pressing cavity. The pressing cavity is used to hold raw materials. The gland 103 is used to cover the raw materials in the pressing cavity and is pressed down by the pressing mechanism, thereby pressing the raw materials in the pressing cavity into tea bricks. The limiting piece 104 is used to limit the position of the gland 103 after the tea bricks are pressed and formed by cooperating with the limiting hole pre-set on the base 101.

[0038] The support assembly 200 is used to support the limiting tea brick mold 100, and a pressing mechanism is arranged above the support assembly 200. The support assembly 200 is further provided with a raw material feeding mechanism 300, a limiting piece dismounting mechanism 400, a mold body transfer mechanism 500, a limiting piece assembling mechanism 600, a mold discharging conveying belt 700 and a mold feeding conveying belt 800. The raw material feeding mechanism 300 is used to convey raw materials to the pressing cavity. The limiting piece assembling mechanism 600 is used to insert the limiting piece 104 into the preset limiting hole on the base 101. The mold discharging conveying belt 700 is used to transfer the tea brick mold 100 with the assembled limiting piece 104 to prolong the pressing time of the tea brick. The mold feeding conveying belt 800 is used to transfer the tea brick mold 100 discharged by the mold discharging conveying belt 700 to the work station of the limiting piece dismounting mechanism 400. The limiting piece dismounting mechanism 400 is used to push out the limiting piece 104 of the tea brick mold 100. The mold body transfer mechanism 500 is used to transfer the mold body 102 away from the base 101 after the limiting piece 104 is pushed out. The limiting piece dismounting mechanism 400 is further used to push the base 101 to the position below the raw material feeding mechanism 300 after the mold body 102 is transferred away from the base 101.

[0039] Here, the meaning of the "mold body 102" refers to a structure used to be placed on the base 101 to form a pressing cavity for containing raw materials. In some embodiments, the mold body 102 is a frame structure with an upper opening and a lower opening.

[0040] Here, the meaning of the "support assembly 200" refers to a mounting rack structure that provides support and limitation for the tea brick mold 100 and provides mounting support for the raw material feeding mechanism 300, the limiting piece dismounting mechanism 400, the mold body transfer mechanism 500 and the limiting piece assembling mechanism 600. In some embodiments, the support assembly 200 is a whole back-shaped closed loop structure. A discharging support 201 is arranged on both sides of the mold discharging conveying belt 700 to provide limitation on both sides of the tea brick mold 100 with the completed pressing and molding and the assembled limiting piece 104 when the tea brick mold 100 is transferred by the mold discharging conveying belt 700. Meanwhile, a feeding support 203 is arranged on both sides of the mold feeding conveying belt 800 to limit both sides of the tea brick mold 100 on the mold feeding conveying belt 800. A first transfer support 202 is arranged between the discharging end of the mold discharging conveying belt 700 and the feeding end of the mold feeding conveying belt 800. A pushing material driving device 900 is arranged beside the first transfer support 202. The pushing material driving device 900 pushes the tea brick mold 100 and transfers the tea brick mold 100 from the mold discharging conveying belt 700 to the mold feeding conveying belt 800 through the first transfer support 202.

[0041] In addition, the support assembly 200 is provided with a second transfer support 204 between the limiting piece dismounting mechanism 400 and the limiting piece assembling mechanism 600, and the base 101 is transferred through the second transfer support 204; the support assembly 200 is provided with a discharging support 201 in front of the feeding end of the mold discharging conveying belt 700, and the discharging support 201 is used for placing the mold body 102, so as to manually control the feeding rhythm of the mold body 102; the support assembly 200 is provided with a mold discharging support 205 at the rear side of the discharging end of the mold feeding conveying belt 800, and the mold body 102 is supported and transferred through the mold discharging support 205 when being towed by the mold body transferring mechanism 500; the third transfer support 206 is arranged between the mold discharging support 205 and the mold feeding support 207, and the fourth driving device 501 is arranged beside the third transfer support 206, and the fourth driving device 501 is used for pushing the mold body 102 to be transferred from the mold discharging support 205 to the mold feeding support 207 through the third transfer support 206. In this way, the overall transfer of the tea brick mold 100 can be realized through the support assembly 200, and the transfer of the base 101 and the mold body 102 can be realized respectively after the limiting piece 104 is dismounted, so as to effectively reduce the workload and working strength of manual carrying, and be beneficial to further improving the transfer efficiency and overall production efficiency.

[0042] The tea brick production equipment of the present application can press and form tea bricks through the tea brick mold 100, wherein the limiting piece 104 can limit the gland 103 through the pre-set limiting hole on the base 101, so as to maintain the continuous and stable pressing of the tea brick in the pressing cavity by the gland 103, ensure that the tea brick in the tea brick mold 100 is continuously pressed after being formed, and prevent excessive deformation in the subsequent cooling stage from causing problems such as reduced product quality or even scrap.

[0043] Meanwhile, the support assembly 200 is used for supporting and limiting the tea brick mold 100, the raw material feeding mechanism 300 is used for conveying raw materials to the pressing cavity, so as to reduce the labor intensity of manual feeding; the compacting mechanism is used for completing the compacting and forming of the raw materials in the pressing cavity; the limiting piece assembling mechanism 600 is used for inserting the limiting piece 104 into the pre-set limiting hole on the base 101, so as to realize the continuous limiting and pressing of the formed tea brick, and then the limiting piece dismounting mechanism 400 can push out the limiting piece 104 of the tea brick mold 100 after the cooling of the tea brick is completed, so as to realize the rapid dismounting of the limiting piece 104; then the mold body transferring mechanism 500 can transfer the mold body 102 away from the base 101 after the limiting piece 104 is pushed out, so as to reduce the labor intensity and workload of manually carrying the mold body 102 for a long distance, and the base 101 can also be pushed to below the raw material feeding mechanism 300 by manual operation or the limiting piece dismounting mechanism 400, so as to facilitate the reassembly with the mold body 102, improve the efficiency of the overall circulation and utilization of the tea brick mold 100, and further improve the production efficiency.

[0044] Preferably, please refer to Figure 1 and Figure 3 As shown in the drawings, the base 101 is provided with a first limiting plate 1011 and a second limiting plate 1012 on opposite sides along the length direction of the base 101, the pre-set limiting holes on the base 101 include first limiting holes on the first limiting plate 1011 and second limiting holes on the second limiting plate 1012, the first limiting holes are larger than the second limiting holes, the top surface of the limiting piece 104 is a beveled structure, and the limiting piece 104 is used to pass through the first limiting holes and the second limiting holes in sequence and press the gland 103 tightly through the bottom surface of the limiting piece 104.

[0045] It can be understood that the limiting cavity is formed between the first limiting plate 1011 and the second limiting plate 1012, and the limiting cavity is used to limit the mold body 102. The top surface of the limiting piece 104 is a beveled structure, and when the limiting piece 104 passes through the larger first limiting holes and the smaller second limiting holes in sequence, the top surface of the limiting piece 104 is in interference fit with the first limiting holes and the smaller second limiting holes, and the bottom surface of the limiting piece 104 presses the gland 103 tightly, so that the tight locking effect can be achieved, and the limiting piece 104 can only be installed in a top-in type from the direction of the first limiting holes. The two ends of the limiting piece 104 are installed and limited through the cooperation of the first limiting holes and the second limiting holes and the limiting piece 104, which not only can ensure the assembly stability of the limiting piece 104, but also is beneficial to the quick insertion installation and quick extraction disassembly of the limiting piece 104. Compared with the existing tea brick mold which limits the gland 103 through the tightening of multiple bolts, the working strength and workload are greatly reduced, and the production efficiency is further improved.

[0046] It should be noted that during the cooling and stress release stage after the tea brick in the pressing cavity is pressed and formed, the tea brick may rebound and thus be prone to deformation and other phenomena. At this time, the rebounding volume of the tea brick will push the gland 103 upward, and the limiting piece 104 can play a role in locking and limiting. The more the gland 103 is pushed upward, the tighter the interference fit between the limiting piece 104 and the first limiting holes and the second limiting holes, and the locking and limiting effect is continuously strengthened, so as to ensure the precision of the volume of the pressing cavity, reduce the deformation amount of the tea brick, and ensure the quality of the product.

[0047] Preferably, please refer to Figure 1 、 2 As shown in the drawings, the raw material feeding mechanism 300 includes a raw material feeding conveyor belt 301, a weighing assembly 302 and a material conveying belt 303 connected in sequence from top to bottom. The raw material feeding conveyor belt 301 is used to transport raw materials to the weighing assembly 302 in an interval type. The weighing assembly 302 is used to weigh the raw materials and discharge a certain amount of raw materials to the material conveying belt 303. The material conveying belt 303 is used to convey the certain amount of raw materials to different pressing cavities in batches.

[0048] It can be understood that the raw materials are transported into the weighing assembly 302 through the raw material feeding conveyor 301, and the raw materials are weighed through the weighing assembly 302. When a certain amount is reached, the raw material feeding conveyor 301 stops transporting the raw materials. In this way, the weighing assembly 302 cooperates with the raw material feeding conveyor 301 to transport the raw materials in an interval mode, complete the quantitative weighing of the raw materials, and then discharge the quantitative raw materials to the material distribution conveyor 303. The quantitative raw materials can be put into the pressing cavity. Compared with manual weighing and feeding into the pressing cavity, the labor intensity is greatly reduced, the efficiency is higher, and the quantitative is more accurate.

[0049] Preferably, please refer to Figure 4 、 5 , 6, the weighing assembly 302 includes an open-top weighing box, the bottom of the weighing box is connected with the electronic scale 307, the first storage part 3023 and the second storage part 3024 are oppositely arranged in the weighing box along the discharging direction, the middle part of the first storage part 3023 is hinged to the side wall of the weighing box, and the bottom of the first storage part 3023 and the second storage part 3024 is used for mutual abutment to form a temporary storage cavity between the first storage part 3023 and the second storage part 3024. The temporary storage cavity is used for receiving the raw materials transferred by the raw material feeding conveyor 301. The first driving device 3026 is arranged in the weighing box, and the first driving device 3026 is used to drive the bottom of the first storage part 3023 to rotate around the hinge point of the first storage part 3023, and then separate from the second storage part 3024 to open the temporary storage cavity for discharging.

[0050] It can be understood that the bottom of the first storage part 3023 and the second storage part 3024 abut against each other to form a temporary storage cavity in the shape of an inverted triangle between the first storage part 3023 and the second storage part 3024. The first driving device 3026 can drive the first storage part 3023 to rotate to separate from the second storage part 3024, open the outlet at the bottom of the temporary storage cavity, and then realize automatic discharging of the raw materials under the action of gravity. The structure of the temporary storage cavity is very simple, and the control is very convenient and fast, which can realize efficient quantitative weighing and rapid discharging effect.

[0051] It should be noted that the electronic scale 307 and the weighing box are fixedly installed. The weight change of the weighing box can be monitored in real time through the electronic scale 307. When the preset weight is reached, the first driving device 3026 is started to open the temporary storage cavity for discharging, and the raw material feeding conveyor 301 stops transporting the raw materials at the same time. Since the control steps are intermittent, timely and accurate control effect can be achieved.

[0052] In some other embodiments, the electronic scale 307 is fixedly installed, a compression spring 308 is arranged between the bottom of the weighing box and the electronic scale 307, the compression spring 308 is used to provide an elastic force for pushing the weighing box to the electronic scale 307, a first sensor 304 is arranged on the side wall of the weighing box, and a second sensor 305 is arranged on the electronic scale 307, when the raw materials in the weighing box continuously increase to cause the weighing box to move downward, the first sensor 304 moves downward and triggers the second sensor 305, and then triggers the first driving device 3026 to start, and stops the raw material conveying of the raw material feeding conveyor belt 301.

[0053] Optionally, a sensor bracket 306 is arranged on the electronic scale 307, and a plurality of second sensors 305 are arranged on the sensor bracket 306, so that the quantitative weighing control of raw materials of different weights can be realized. The first sensor 304 and the second sensor 305 can be distance sensors.

[0054] Preferably, as shown in Figure 4 、 5 The opposite sides of the weighing box are respectively provided with a first side plate 3021 and a second side plate 3022, the top of the first storage part 3023 is connected with the first side plate 3021 through an elastic element 3029, the top of the second storage part 3024 is connected with the second side plate 3022 through an elastic element 3029, and one side of the first storage part 3023 and the second storage part 3024 facing the temporary storage cavity is uniformly provided with a limiting partition plate 3028.
