DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0029] As shown in Figure 1 - Figure 8 A tea forming machine, comprising a rack 1, a first conveying belt 21 mounted on the rack 1 and a first driving part 211 for driving the first conveying belt 21 to move, the first conveying belt 21 has a feeding station and a discharging station at both ends of the conveying direction of the first conveying belt 21, characterized in that: a pressing station is arranged on the rack 1 in cooperation, the pressing station is provided with a first pressing assembly 22, the first pressing assembly 22 comprises a vertical air cylinder 221 above the first conveying belt 21, the rack 1 is provided with a support seat 11 for mounting the vertical air cylinder 221, the number of the support seat 11 and the vertical air cylinder 221 in the application is two, the output end of the vertical air cylinder 221 is vertically directed to the first conveying belt 21, the output end of the vertical air cylinder 221 is provided with the same pressing plate 222, the rack 1 is provided with a scraper 29 matched with the pressing plate 222, the scraper 29 is arranged on both sides of the pressing plate 222, the scraper 29 is used for pushing the formed tea 100 adhered on the pressing plate 222, and the vertical air cylinder 221 drives the pressing plate 222 to reciprocate in the vertical direction.

[0030] It should be noted that the pressing plate 222 is a thin plate, when the vertical cylinder 221 is in the closed state, the pressing plate 222 is in the upper limit position in the movement direction, at this time the bottom of the pressing plate 222 is above the bottom position of the scraper 29, so that the formed tea 100 can be pushed down by the scraper 29.

[0031] In use, the pressing plate 222 moves to the side close to the first conveying belt 21 under the drive of the vertical cylinder 221, and at the same time the first conveying belt 21 stops moving, so that the tea 100 is processed and formed by the pressing plate 222 pressing down, and after the tea 100 is formed, the vertical cylinder 221 is closed to drive the pressing plate 222 to move away from the first conveying belt 21. Because the tea 100 may squeeze out the juice in part of the tea 100 when it is pressed by the pressing plate 222, the formed tea 100 may be adhered to the pressing plate 222 at the part where the juice exists, and the part of the tea 100 not adhered to the pressing plate 222 hangs below the pressing plate 222 due to gravity, and there is an included angle between the hanging part of the tea 100 and the length direction of the pressing plate 222. Therefore, if the tea 100 is adhered to the bottom of the pressing plate 222, the pressing plate 222 will slide relative to the scraper 29 in the process of rising, so that the bottom of the scraper 29 contacts the hanging part of the tea 100 adhered to the bottom of the pressing plate 222, and then the tea 100 adhered to the bottom of the pressing plate 222 is pushed down by the scraper 29.

[0032] The two sides of the scraper 29 are respectively arranged in abutment with the two side surfaces of the pressing plate 222, and the scraper 29 comprises a mounting plate 291, a connecting plate 292 and a contact plate 293. The connecting plate 292 is arranged between the mounting plate 291 and the contact plate 293, and in this application, the contact plate 293 and the mounting plate 291 are parallel to each other. The mounting plate 291 is fixedly installed on the support seat 11.

[0033] In addition, a transmission assembly 212 is connected between the first driving member 211 and the first conveying belt 21 in this application. The transmission assembly 212 is a chain transmission in this application, and other transmission connection mechanisms such as a belt transmission can also be used instead.

[0034] The pressing station further comprises a second pressing assembly 23 for pressing the tea 100 in the horizontal direction. The second pressing assembly 23 comprises a horizontal cylinder 231, and the horizontal cylinder 231 is located on both sides of the first conveying belt 21. The output end of the horizontal cylinder 231 horizontally faces the first conveying belt 21, and the output end of the horizontal cylinder 231 is provided with a clamping plate 232, and the bottom of the clamping plate 232 abuts with the upper end surface of the first conveying belt 21. When the horizontal cylinder 231 drives the clamping plates 232 on both sides to move to the middle of the first conveying belt 21, there is a gap between the two clamping plates 232 for the movement of the pressing plate 222.

[0035] When the tea leaves 100 are pressed into strips: the two clamping plates 232 are driven by the horizontal cylinder 231 to move towards each other at one end or move away from each other at one end at the same time, thereby achieving the functions of clamping and loosening the tea leaves 100, and when the two clamping plates 232 move towards each other at one end, the pressing plate 222 moves towards the side close to the first conveying belt 21 at this time by the driving of the vertical cylinder 221, and at the same time the first conveying belt 21 stops moving, and then the tea leaves 100 are pressed into long strips, thereby realizing the processing and forming of the tea leaves 100.
