DETAILED DESCRIPTION

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Figures 1-6 As shown, the system includes a base plate 1, a coating furnace 2, a track 21, a furnace door 22, a cylinder 3, a film material passage pipe 4, a pressure extraction connector 5, and a feeding mechanism 6. The coating furnace 2 is located on the top of the base plate 1, and the coating furnace 2 contains a coating chamber for coating processing. The track 21 is located on the front top of the base plate 1, and the furnace door 22, which can be slidably installed on the track 21, can close the coating furnace 2. When the furnace door 22 completely covers the coating furnace 2, the interior of the coating chamber is sealed. The cylinder 3 is located on the top of the coating furnace 2, and the end of the movable rod of the cylinder 3 is connected to the upper left of the furnace door 22. The furnace door 22 is opened and closed by the cylinder 3. The pressure extraction connector 5, which is connected to an external pressure extraction device, is located on the upper left side of the coating furnace 2. Before coating, the pressure extraction device connected to the pressure extraction connector 5 is used to evacuate the coating furnace 2 to remove the gas and prevent the gas remaining in the furnace from reacting with the film material, which could lead to quality problems on the film surface.

[0025] Among them, such as Figure 6 As shown, the lower left and right sides of the coating furnace 2 are equipped with film material inlet pipes 4, which connect to external equipment for heating and vaporizing the film material. The vaporized film material is intermittently fed into the coating chamber through the film material inlet pipes 4. The lower part of the coating furnace 2 is equipped with a feeding mechanism 6, which includes a limiting frame 61, a mounting base 62, a motor 63, and a feeding wheel 65. The limiting frame 61 is fixedly installed at the lower part of the coating chamber of the coating furnace 2. The limiting frame 61 is arranged in a ring shape and has a notch at its lower part. The mounting base 6 is located at the rear of the coating chamber of the coating furnace 2, concentric with the limiting frame 61. 2. The mounting base 62 is equipped with a motor 63 that provides rotational driving force. A feeding wheel 65 for transmitting bamboo chopsticks is fixedly installed on the output shaft of the motor 63. The motor drives the feeding wheel 65 to rotate within the limiting frame 61. Several clamping grooves are evenly spaced on the feeding wheel 65. Before coating, the bamboo chopsticks are placed in the clamping grooves. When the feeding wheel 65 rotates, it is restricted by the outer limiting frame 61. When the feeding wheel 65 rotates, the bamboo chopsticks will only fall out from the notch of the lower limiting frame 61 of the feeding wheel 65.

[0026] When the bamboo chopsticks need to be plated, first place the bamboo chopsticks in the material feeding wheel 65, since the front and rear width of the material feeding wheel 65 is relatively narrow, when placing the bamboo chopsticks, the edible area of the bamboo chopsticks which does not need to be plated is inserted between the limiting frame 61 and the material feeding wheel 65, and the two parts shield the part of the bamboo chopsticks, then the furnace door 22 is closed by the cylinder 3, then the gas in the plating furnace 2 is extracted by the extraction and pressing device connected to the extraction and pressing joint 5, then the film material is sent into the plating chamber through the film material pipe 4, and the film material is deposited on the surface of the object to be plated by gas diffusion, after a certain period of time, the motor 1 63 is started to drive the material feeding wheel 65 to rotate, when the bamboo chopsticks rotate to the lower part of the material feeding wheel 65, they will fall out of the gap of the limiting frame 61 for discharging, after the plating is completed, the furnace door 22 is opened and the bamboo chopsticks are taken out to complete the processing.

[0027] Example 2: based on example 1, as shown in Figures 1-3 The discharging mechanism 7 is further included, the left upper side of the limiting frame 61 is provided with the discharging mechanism 7 which can centrally place the bamboo chopsticks and does not need manual feeding, the discharging mechanism 7 includes a hopper 71, a distributing wheel 72, a motor 2 73 and a discharging pipe 74, the left upper side of the limiting frame 61 is provided with the hopper 71 which can centrally feed the bamboo chopsticks in batches, when placing the bamboo chopsticks, the bamboo chopsticks are placed flat with the two ends facing the front and rear sides, the hopper 71 is rotatably provided with the distributing wheel 72 on the left lower side of the inner side of the hopper 71, which intermittently and orderly discharges the bamboo chopsticks in the hopper, a plurality of distributing grooves are opened on the distributing wheel 72, when the distributing wheel 72 rotates, the bamboo chopsticks will fall into the distributing grooves of the distributing wheel 72, and the width and depth of the distributing grooves are set to allow only one bamboo chopstick to be placed at a time, the front side of the hopper 71 is provided with the motor 2 73 which drives the distributing wheel to rotate, the output shaft of the motor 2 73 is fixedly connected with the distributing wheel 72, the hopper 71 is connected and communicated with the discharging pipe 74, the lower part of the discharging pipe 74 penetrates into the limiting frame 61, the lower part of the discharging pipe 7 is communicated with the left upper gap between the limiting frame 61 and the distributing wheel 72, when the bamboo chopsticks are discharged from the hopper 71 to the discharging pipe 74 by the distributing wheel 72, the bamboo chopsticks will fall outside the material feeding wheel 65 and fall into the material feeding wheel 65 when the material feeding wheel 65 rotates, the discharging and feeding are realized by the discharging mechanism 7 and the material feeding wheel 65.

[0028] As shown in Figures 1-2 The receiving frame 10 and the hollow plate 101 are further included, the receiving frame 10 which centrally collects the bamboo chopsticks after plating is slidably arranged in the lower part of the plating furnace 2, the hollow plate 101 is arranged on the inner side of the receiving frame 10 to facilitate the later drying treatment;

[0029] Before coating, a large number of bamboo chopsticks are placed in the hopper, and the bamboo chopsticks in the hopper flow to the left due to the shape of the hopper. During coating, the rotation speed of the distribution wheel 72 and the feeding wheel 65 is controlled by controlling the coordination rhythm between the motor one 63 and the motor two, so as to control the optimal rate of feeding and conveying. The bamboo chopsticks are fed from the left upper part of the feeding wheel 65 and are conveyed along with the clockwise rotation of the feeding wheel 65. When the feeding wheel 65 is conveying, the bamboo chopsticks are coated. After coating, the bamboo chopsticks rotate to the lower part of the feeding wheel 65 and fall off the feeding wheel 65. The bamboo chopsticks falling downward fall into the receiving frame 10. The bamboo chopsticks are continuously discharged by the discharge mechanism and the receiving part. The bamboo chopsticks are sequentially conveyed and coated by the feeding device, and the processed bamboo chopsticks are collected. The bamboo chopsticks are continuously and sequentially processed, the manual intervention is reduced, the processing efficiency is effectively improved, the furnace door 22 is opened after processing, and the receiving frame 10 is taken away by sliding forward for subsequent processing.

[0030] In a specific embodiment, as shown in Figures 2-5 The friction mechanism 8 is further provided on the feeding mechanism 6 to rotate the bamboo chopsticks. The friction mechanism 8 includes a support one 81, a support two 82, a bevel gear set 83, a shaft sleeve 84 and a friction wheel 85. The support one 81 is fixedly arranged at the front of the mounting seat 62, and the output shaft of the motor one 63 passes through the support one 81. The support two 82 is arranged at the left middle part of the support one 81. The support two 82 and the output shaft of the motor one 63 are provided with the bevel gear set 83. The bevel gear set 83 is composed of three bevel gears. The two bevel gears at the front and back are arranged in front-to-back direction and are engaged with the middle bevel gear. The bevel gear at the back is fixedly connected with the output shaft of the motor one 63 and rotates with the motor one 63, so as to drive the bevel gear at the left of the support two 82 to rotate, and then drive the bevel gear at the front to rotate. At this time, the power of the output shaft of the motor one 63 is reversed when the power is transmitted to the bevel gear at the front under the transmission of the middle bevel gear. The bevel gear at the front of the support two 82 is rotatably contacted with the output shaft of the motor one 63 through the shaft sleeve 84. The shaft sleeve 84 is opposite to the output shaft of the motor one 63 under the transmission of the bevel gear at the left of the support two 82. The friction wheel 85 is fixedly arranged at the front of the shaft sleeve 84 and is arranged in a stepped shape at the outer edge. The friction wheel 85 is embedded into the feeding wheel 65, and the convex drum part of the feeding wheel 65 is at the same height with the groove bottom of the material clamping groove of the feeding wheel 65.

[0031] When the motor 63 works, under the transmission of the bevel gear set, the friction wheel 85 on the shaft sleeve 84 rotates in the opposite direction of the feeding wheel 65 on the output shaft of the motor 63. When the feeding wheel 65 feeds the bamboo chopsticks, the friction wheel 85 will contact the surface of the bamboo chopsticks and rotate in the opposite direction of the friction wheel 85, driving all the bamboo chopsticks in the feeding wheel 65 to rotate. When coating, the surface of the bamboo chopsticks is in full and uniform contact with the gas-phase film material in the coating furnace 2, ensuring that the film material attached to the bamboo chopsticks has consistent thickness and improving the uniformity of the film.

[0032] In a specific embodiment, as shown in Figures 1-2 , it further includes a cover 9 and a connecting pipe 91. The cover 9 is fixedly connected to the front part of the limiting frame 61 and completely seals the front part of the limiting frame 61. The cover 9 has a discharge gap in the lower part, which is consistent in size with the lower side of the limiting frame 61. The cover 9 is connected and communicated with the connecting pipe 91 on the left and right sides, and the connecting pipes 91 on the left and right sides are respectively connected to the film material pipes 4 on the left and right sides.

[0033] When the film material pipes 4 feed the film material, the connecting pipes guide the film material into the feeding mechanism. The cover 9 divides a small space in the coating furnace 2, accurately guides the film material for coating, reduces the coating area required to be filled with gas-phase film material, reduces the waste of film material, shortens the process from feeding to film attachment, and improves the coating efficiency.

[0034] In a specific embodiment, as shown in Figure 1 , Figure 2 , Figure 6 and Figure 7 , it further includes a recovery mechanism 11. The recovery mechanism 11 is arranged on the upper rear side of the coating furnace 2 to recover the film material that escapes outside the cover 9 during coating. The recovery mechanism 11 includes an exhaust group 111, a condenser 112, exhaust pipes 113, and a liquid discharge pipe 114. The exhaust group 111 is provided with an internal suction pump on the upper rear side of the coating furnace 2 to provide suction power. The front part of the exhaust group 111 penetrates into the coating furnace 2. The rear part of the exhaust group 111 is provided with a condenser 112. The left and right sides of the exhaust group 111 are symmetrically provided with not less than four exhaust pipes 113. The front ends of the exhaust pipes 113 are in communication with the inside of the coating furnace 2. The other ends of the exhaust pipes 113 are in communication with the condenser 112. When the exhaust group 111 works, it will extract the gas-phase film material in the furnace. The extracted gas-phase film material flows into the condenser 112 through the exhaust pipes. The upper part of the condenser 112 is provided with a connector connected to a cooling device. The cooling device quickly liquefies the gas-phase film material discharged into the condenser 112 and discharges it through the liquid discharge pipe 114 arranged in the condenser 112, reducing the waste of film material during coating and effectively reducing the processing cost.

[0035] In a specific embodiment, as shown in Figure 1As shown, it also includes a viewing window 12. The furnace door 22 is provided with a transparent viewing window 12 that allows observation of the working status inside the coating furnace 2, facilitating timely processing adjustments.
