The guide roller 120 rotates to guide the plastic sealing member and the plastic sealing film into the preheating space 104. In the preheating space 104, the temperature of the plastic sealing member and the plastic sealing film gradually rises. When the guide roller 120 transfers the plastic sealing member and the plastic sealing film to the plastic sealing roller 140, the distance traveled by the plastic sealing film and the plastic sealing member is h. The heating component 130 heats the temperature of the plastic sealing roller 140 and the plastic sealing space 103 to the first plastic sealing temperature te1. At this temperature, the plastic film melts, and the plastic roller 140 presses and fixes the plastic film on the plastic part. When in use, there is no need to start the plastic sealing machine and wait for the plastic sealing roller to reach the plastic sealing temperature. The plastic sealing film and the plastic sealing part can be directly put into the feed port, and the time for the guide roller to transport the plastic sealing film and the plastic sealing part is used to make the plastic sealing roller 140 reach the first plastic sealing temperature te1, so as to achieve plastic sealing, which is convenient for users to use; preferably, the preset distance H is 4 cm.

[0037] In this embodiment, the main body 110 includes an upper mounting member 111 and a lower mounting member 112, the upper mounting member 111 is connected to the lower mounting member 112, and the preheating space 104 is formed between the upper mounting member 111 and the lower mounting member 112, and the upper mounting member 111 and the lower mounting member 112 are both provided with a heat conducting plate 113, and the heat conducting plate 113 is extended along the surface of the upper mounting member 111 and / or the surface of the lower mounting member 112 toward the guide roller 120, and the preheating space 104 is formed between the two heat conducting plates 113. Through the arrangement of the above structure, the upper mounting member 111 and the lower mounting member 112 are connected to form a roughly sealed preheating space 104, and the heating component 130 and the plastic sealing roller 140 can be accommodated in the preheating space 104. On the one hand, the heating component 130 and the plastic sealing roller 140 can be protected to prevent external debris from contaminating the heating component 130 and the plastic sealing roller 140, and the heating efficiency can be improved to enable the plastic sealing roller 140 to reach the plastic sealing temperature faster; and the heat conducting plate 113 protruding from the surface of the upper mounting member 111 and / or the surface of the lower mounting member 112 can conduct heat, and the preheating space 104 formed between the two heat conducting plates can preheat the plastic sealing film and the plastic sealing parts to increase the temperature of the two, so that when the plastic sealing roller 140 is plastic sealing, the temperature of the plastic sealing film and the plastic sealing parts can reach the plastic sealing temperature, thereby improving the plastic sealing efficiency of the product.

[0038] In this embodiment, the end of the heat conducting plate 113 is provided with a first guide portion 114, and the two first guide portions 114 are extended in opposite directions. Through the above-mentioned structure, the two first guide portions 114 are extended in opposite directions, and a trumpet-shaped opening design can be formed at the entrance of the preheating space 104. When in use, when the guide roller 120 is transmitting the plastic film and the plastic parts, the plastic film and the plastic parts can enter the preheating space 104 more easily, and the plastic film and the plastic parts are prevented from being stuck at the entrance of the preheating space 104, thereby improving the use efficiency of the product and reducing the failure rate.

[0039] In this embodiment, the upper mounting member 111 and the lower mounting member 112 are both provided with a guide plate 115, and a guide channel 105 is formed between the two guide plates 115. The guide channel 105 is arranged opposite to the discharge port 102. Through the arrangement of the above structure, the lower end of the upper mounting member 111 and the upper end of the lower mounting member 112 are both provided with a guide plate 115, and the two guide plates 115 are arranged opposite to each other, and a guide channel 105 is formed between the two, which can allow the hot-pressed plastic film and the plastic parts to be gradually transmitted along the guide channel 105 and finally discharged along the discharge port 102, so that the user can obtain the final plastic-sealed product conveniently, prevent the plastic film and the plastic parts from being stuck in front of the discharge port 102, and improve the plastic sealing efficiency of the product.

[0040] In this embodiment, the two guide plates 115 are provided with a second guide portion 116 on one side facing the plastic sealing roller 140, and the two second guide portions 116 are extended in opposite directions. Through the above-mentioned structure, when in use, the two second guide portions 116 arranged in opposite directions form a trumpet-shaped opening, and the opening is directly opposite to the plastic sealing roller 140. After the plastic sealing film and the plastic sealing parts are hot-pressed and plastic sealed by the plastic sealing roller 140, they enter the guide channel 105 along the opening, and then are transmitted to the discharge port 102 along the guide channel 105, so that the plastic sealing parts can be smoothly discharged, thereby preventing the occurrence of jamming and other faults, and improving the use efficiency of the product.

[0041] In this embodiment, a driving device 150 is further included. The driving device 150 is disposed in the main body 110 and connected to the plastic sealing roller 140 and the guide roller 120 through a gear set 151. The driving device 150 drives the plastic sealing roller 140 and the guide roller 120 to rotate. Through the above-mentioned structure, the output end of the driving device 150 rotates, driving the gear set 151, and then driving the plastic sealing roller 140 and the guide roller 120 to rotate, wherein the plastic sealing roller 140 includes two plastic sealing rollers 140, which are disposed opposite to each other up and down, and rotate in opposite directions; similarly, the guide roller 120 also includes two guide rollers 120, which are disposed opposite to each other up and down, and rotate in opposite directions.

[0042] In this embodiment, a temperature detection device 160 and a control device 170 are also included. The temperature detection device 160 is arranged in the main body 110. The temperature detection device 160 detects the temperature t in the plastic packaging space 103 and outputs a first electrical signal. The control device 170 is electrically connected to the temperature detection device 160 and the driving device 150. The control device 170 is used to receive the first electrical signal generated by the temperature detection device 160 and adjust the rotation speed of the driving device 150 accordingly. Through the arrangement of the above structure, when in use, the plastic sealing parts and the plastic sealing film are put in along the feed port 101, and the driving device 150 runs at a preset initial rotation speed v0. At this time, the heating component 130 works, and the temperature of the plastic sealing roller 140, the plastic sealing space 103 and the preheating space 104 gradually rises. The guide roller 120 rotates to guide the plastic sealing parts and the plastic sealing film into the preheating space 104. In the preheating space 104, the temperature of the plastic sealing parts and the plastic sealing film gradually rises. When the guide roller 120 transmits the plastic sealing parts and the plastic sealing film to the plastic sealing roller 140, the distance traveled by the plastic sealing film and the plastic sealing parts is h. The heating component 130 heats the temperature of the plastic sealing roller 140 and the plastic sealing space 103 to the first plastic sealing temperature te1. The temperature detection device 160 detects the first plastic sealing temperature te1 at this time and outputs a first electrical signal, and the control device 170 adjusts the driving device according to the signal. The rotation speed of 150 reaches v1; at different temperatures, the melting degree of the plastic film is different. When the temperature is low, in order to ensure that the plastic film is tightly connected to the plastic part, the plastic roller 140 needs to press the plastic film onto the plastic part for a longer time. Therefore, the control device 170 controls the driving device 150 to reduce the rotation speed to increase the contact time between the plastic roller 140 and the plastic film and the plastic part, improve the success rate of plastic sealing, and ensure the plastic sealing effect; and when a group of plastic sealing films and plastic sealing parts are plastic sealed, the next group of plastic sealing films and plastic sealing parts enter through the feed port. At this time, the heating component 130 continues to work, so that the temperature in the plastic sealing roller 140 and the plastic sealing space 103 continues to rise, and when the next group of plastic sealing parts reaches the plastic sealing roller 140, the plastic sealing roller 140 has a higher plastic sealing temperature te2. At this time, the rotation speed of the driving device 150 can be increased to v2 to improve the plastic sealing efficiency. Preferably, a button 171 is also provided on the control device 170, and the user can select different modes through the button. Corresponding to different thicknesses of the plastic film, the control device 170 will adjust the rotation speed of the drive device 150. Generally, the thicker the plastic film, the higher the required plastic temperature, and the longer the time required for the plastic roller to contact and hot-press the plastic film. Therefore, when the thickness of the plastic film is thicker, the control device 170 controls the drive device 150 to reduce the rotation speed.

[0043] In this embodiment, the temperature detection device 160 is also used to detect whether the temperature t in the plastic sealing space 103 is less than the preset temperature T, and outputs a second electrical signal when the temperature t in the plastic sealing space 103 is less than the preset temperature T, and the control device 170 receives the second electrical signal and controls the heating component 130 to heat. Through the above-mentioned structure, when in use, when the plastic sealing film and the plastic sealing parts pass through the plastic sealing roller 140, the plastic sealing film and the plastic sealing parts will absorb a certain amount of heat, so that the temperature of the surface of the plastic sealing roller 140 decreases, and the temperature detection device 160 detects the temperature decrease, and then outputs a second electrical signal, and the control device 170 controls the heating component 130 to work, so that the temperature of the surface of the plastic sealing roller 140 rises to the plastic sealing temperature again, so that the temperature is kept near the plastic sealing temperature, to ensure the temperature stability, and then to ensure the plastic sealing effect.

[0044] In this embodiment, the heating assembly 130 includes a plurality of heating elements 131, and the heating elements 131 are arranged around the plastic sealing roller 140. Through the above-mentioned structure, the plurality of heating elements 131 are arranged around the plastic sealing roller 140, which can enhance the heating effect and make the temperature in the plastic sealing space 103 uniform, thereby achieving a good plastic sealing effect; preferably, the heating element 131 is a high-power heating element such as a heat pipe, which can increase the heating rate and improve the plastic sealing effect.

[0045] In this embodiment, a supporting plate 180 is further included, and the supporting plate 180 is arranged on one side of the main body 110 close to the discharge port 102 and extends along the plane where the discharge port 102 is located, and the upper surface of the supporting plate 180 is arranged below the discharge port 102. With the arrangement of the above structure, when in use, the plastic-sealed parts and the plastic-sealed films are plastic-sealed by the plastic-sealing roller 140 and discharged along the guide channel 105 and the discharge port 102, and the supporting plate 180 can effectively support the plastic-sealed parts to prevent them from being contaminated or damaged.
