[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can heat up the liquid raw material before it is directed to the guide shell by setting an auxiliary mechanism, that is, use the temperature increase method to improve the fluidity of the liquid raw material, so as to ensure that all the liquid raw material inside the liquid storage shell is directed away without residue, thereby ensuring that the amount of liquid raw material delivered to the production equipment each time is the same, that is, to ensure that the quality of the manufactured medical rubber sleeve is improved, which not only improves the use effect of the quantitative feeding device for the production of medical rubber sleeves, but also improves the use efficiency of the quantitative feeding device for the production of medical rubber sleeves. When the first liquid storage shell filled with liquid raw material reaches the bottom of the hollow block and a liquid storage shell that needs to be injected with liquid raw material happens to appear under the guide hole, the controller, the hot air blower, the air outlet pipe, the rectangular plate, the partition and the placement shell are first used to cooperate to realize the hot air discharged from the air outlet of the hot air blower to the inside of the mounting hole.
[0017] 2. The present invention then utilizes the cooperation of the filter screen to filter out the dust or fine particles mixed in the hot air transported from the mounting hole to the fixed ring. At the same time, the heating temperature of the hot air blower can be adjusted by utilizing the cooperation of the temperature sensor and the controller. When the heating temperature of the hot air blower is adjusted, the hollow block, the double-hole plate, the two sealing rings and the air intake pipe can be moved simultaneously by utilizing the cooperation of the controller, two servo electric cylinders, two sets of mounting frames and two connecting plates.
[0018] 3. In the present invention, when the liquid storage shell is sleeved between the insides of the two sealing rings, the two servo electric cylinders can be paused at the same time by using the cooperation of the controller. Then, by using the cooperation of the connecting cover, the insulation hose, the air intake pipe, the two sealing rings, the hollow block, the other circular hole of the double-hole plate and the exhaust port on the hollow block, the liquid raw material in the liquid storage shell can be evenly heated by hot air, that is, the fluidity of the liquid raw material is improved by increasing the temperature.
[0019] 4. The present invention can quantitatively distribute the liquid raw materials that need to be transported and pre-heated by setting a quantitative feeding mechanism, that is, to ensure that the amount of each liquid storage shell on the conveyor is the same. When it is necessary to quantitatively feed the raw materials for the production of medical rubber sleeves to the production equipment, the push plate can be driven to move by the cooperation of the controller, motor, gear, rectangular hole, rectangular groove and L-shaped tooth plate. At the same time, the L-shaped plate can be driven to move by the cooperation of the controller and the electric push rod. Then, the liquid raw material in the guide hole can be quickly guided to the first liquid storage shell on the conveyor directly below the outlet of the guide hole by the cooperation of the moving push plate and the guide hole.
[0020] 5. In the present invention, when no liquid raw material flows out of the outlet of the guide hole, the controller uses the motor, electric push rod, gear, rectangular hole, rectangular groove and L-shaped tooth plate to reset the push plate and the L-shaped plate to their original positions. When the push plate and the L-shaped plate are reset to their original positions, the inside of the guide hole will be refilled with liquid raw material. Then, the controller uses the cooperation of the conveyor to move the liquid storage shell filled with liquid raw material on the conveyor. 6. In the present invention, when the second liquid storage shell moves to the position directly below the guide hole, the controller uses the cooperation of the conveyor to stop the movement of the second liquid storage shell, and then uses the cooperation of the motor and the electric push rod to repeat the above operation steps to inject liquid raw materials into the second liquid storage shell. This reciprocating process can inject liquid raw materials into subsequent liquid storage shells on the conveyor. Then, under the action of the guide shell, the heated liquid raw materials diverted from the liquid storage shell can be diverted to the production equipment to carry out the production operation of the medical rubber sleeve.

A rectangular plate 204 is installed near the top of the front surface of the placement shell 201. A partition 205 is fixed inside the placement shell 201. A mounting hole 206 is opened at the top of the inner wall of the placement shell 201. A filter screen 207 is arranged near the outlet position inside the mounting hole 206. A fixing ring 208 is installed at the top of the placement shell 201. A temperature sensor 209 is installed inside the through hole of the outer wall of the fixing ring 208. The inner surface of each group of mounting frames 210 is provided with a temperature sensor 209. A servo electric cylinder 211 is arranged between the two parts, and a connecting plate 212 is installed on the top of the telescopic end of the two servo electric cylinders 211. A hollow block 213 is fixed between the opposite sides of the two connecting plates 212. The inlet and outlet positions of the hollow block 213 are bonded and connected with a sealing ring 214. A double-hole plate 215 is fixed on the top of the hollow block 213. An air intake pipe 216 is fixedly sleeved inside one of the circular holes of the double-hole plate 215. A heat preservation hose 217 is installed on the air intake end of the air intake pipe 216. A connecting cover 218 is installed on the top of the fixing ring 208. The front surface of the partition plate 205 contacts the surface of the rectangular plate 204. The filter screen 20 The top of the hollow block 213 and the top of the housing 201 are on the same horizontal plane, the bottom of the fixing ring 208 is in contact with the top of the filter screen 207, the detection end of the temperature sensor 209 extends to the inside of the fixing ring 208, the outlet end of the air inlet pipe 216 movably passes through the top of the hollow block 213, and the outlet end of the air inlet pipe 216 extends to the inside of the hollow block 213, the outlet end of the connecting cover 218 is connected to the inlet end of the insulation hose 217, the inside of the other circular hole of the double-hole plate 215 is connected to the inside of the exhaust port on the hollow block 213, the outlet pipe 203 is fixedly passed through the bottom of the partition 205, and the outlet end of the outlet pipe 203 is connected to the exhaust port on the hollow block 213. Near the top of the inner wall of the placement shell 201, there are two mounting frames 210 in each group. The quantitative feeding mechanism 1 includes a conveyor 101. The two groups of mounting frames 210 are respectively mounted on the front surface and the rear surface of the conveyor 101 by first screws. The placement shell 201 is mounted on the surface of the conveyor 101. The surface of the conveyor 101 is installed with a controller 115. The conveying hot air blower 202, the temperature sensor 209 and the two servo electric cylinders 211 are all electrically connected to the controller 115. A U-shaped block 103 is fixed on the top of the conveyor 101, and a guide hole 107 is opened on the top of the inner wall of the U-shaped block 103.
[0025] In this embodiment, when the first liquid storage shell filled with liquid raw materials reaches the bottom of the hollow block 213, a liquid storage shell for liquid raw material injection appears just below the guide hole 107. At this time, the controller 115 will directly start the hot air blower 202, the two servo electric cylinders 211 and the temperature sensor 209. When the hot air blower 202 is started, the hot air blower 202 started at this time will directly inhale and heat the air in the environment, and then transport the heated air to the inside of the air outlet pipe 203. Then the hot air will be directly transported to the inside of the space composed of the rectangular plate 204, the partition plate 205 and the placement shell 201, and then transported to the inside of the mounting hole 206, and then transported to the inside of the fixing ring 208. When the hot air passes through the filter 2 07, the dust or fine particles in the hot air will be filtered out. When more dust or smaller particles accumulate on the surface of the filter 207, the large dust composed of dust or smaller particles will fall into the space composed of the rectangular plate 204, the partition 205 and the placement shell 201 under its own weight. When the hot air enters the interior of the fixing ring 208, the temperature sensor 209 will detect the temperature thereof. Subsequently, the detected hot air will be transported to the interior of the insulation hose 217 with the cooperation of the connecting cover 218, and then transported to the interior of the air intake pipe 216, and then transported to the interior of the hollow block 213, and then discharged from the interior of the hollow block 213 and dispersed into the environment. At the same time , the temperature sensor 209 will directly transmit the detected temperature data to the controller 115 in the form of an electrical signal, and then the controller 115 will compare the received temperature data with the temperature threshold value set in advance by the controller 115. When the temperature data received by the controller 115 is lower than the temperature threshold value set in advance by the controller 115, the controller 115 will continue to increase the heating temperature of the hot air blower 202. When the temperature data received by the controller 115 is the same as the temperature threshold value set in advance by the controller 115, the controller 115 will save the heating temperature of the hot air blower 202 and continue to start the hot air blower 202. At the same time, the controller 115 will also start the two servo electric cylinders 211 at the same time. At this time, the two servo electric cylinders 211 that are started 11 will drive the hollow block 213, the double-hole plate 215, the two sealing rings 214 and the air inlet pipe 216 to move downward at the same time under the cooperation of the two sets of mounting frames 210 and the two connecting plates 212. When the liquid storage shell filled with liquid raw materials is sleeved between the insides of the two sealing rings 214, the controller 115 will simultaneously pause the two servo electric cylinders 211. At this time, under the effect of the continuous injection of hot air into the hollow block 213, the temperature of the liquid raw material in the liquid storage shell will continue to rise. At the same time, the hot air transported to the inside of the hollow block 213 will also be discharged from the inside of the hollow block 213 and discharged into the environment under the cooperation of the other round hole of the double-hole plate 215 and the exhaust port on the hollow block 213. After the liquid raw material in the liquid storage shell is heated for a period of time,At this time, the controller 115 will first turn off the hot air blower 202, and then through the cooperation of two servo electric cylinders 211, two sets of mounting frames 210 and two connecting plates 212, the hollow block 213, the double-hole plate 215, the two sealing rings 214 and the air inlet pipe 216 will be reset to their original positions at the same time. When the hollow block 213, the double-hole plate 215, the two sealing rings 214 and the air inlet pipe 216 are all reset to their original positions, the fluidity of the liquid raw material in the heated liquid storage shell is just right. At the same time, when the raw material inside the liquid storage shell is being heated, the liquid raw material of the new liquid storage shell is also being heated directly below the guide hole 107. When the raw material inside the liquid storage shell is heated, the liquid storage shell directly below the guide hole 107 also completes the liquid raw material injection operation. Then the controller 115 will repeat the above operation steps again to inject the liquid raw material into the next liquid storage shell, and heat the next liquid storage shell filled with liquid raw material. When the liquid storage shell filled with the heated liquid raw material with good fluidity reaches the discharge end of the conveyor 101, the liquid raw material with good fluidity in the liquid storage shell will flow away directly and quickly, and enter the interior of the guide shell 102 without leaving any residue, and then be diverted to the production equipment for use.
[0026] Embodiment 2: According to Figure 1 , Figure 4 and Figure 6-Figure 8As shown, the quantitative feeding mechanism 1 includes a conveyor 101, a guide shell 102 is installed at the discharge end of the conveyor 101, a U-shaped block 103 is fixed on the top of the conveyor 101, a storage shell 104 is fixed on the top of the U-shaped block 103, an annular sealing gasket 109 is bonded and connected to the front surface of the U-shaped block 103, an L-shaped plate 105 is movably penetrated through the rear surface of the U-shaped block 103, the upper side of the L-shaped plate 105 is in contact with the top of the inner wall of the U-shaped block 103, an electric push rod 106 is installed on the rear surface of the U-shaped block 103, one end of the telescopic end of the electric push rod 106 is installed with the surface of the L-shaped plate 105 through a second screw, a guide hole 107 is opened on the top of the inner wall of the U-shaped block 103, a push plate 108 is movably penetrated through the inner wall of the guide hole 107, and the moving end size of the push plate 108 is adapted to the internal size of the guide hole 107 The pushing end of the push plate 108 is movably sleeved inside the annular sealing gasket 109, a rectangular groove 111 is provided on one side of the U-shaped block 103, and a rectangular hole 112 is provided on the front surface of the U-shaped block 103. The interior of the rectangular groove 111 is connected to the interior of the rectangular hole 112, and an L-shaped tooth plate 110 is movably sleeved inside the rectangular hole 112. The other side of the L-shaped tooth plate 110 is fixed to the pushing end surface of the push plate 108. A motor 113 is installed on one side of the U-shaped block 103, and a gear 114 is fixedly sleeved on the outer surface of the output end of the motor 113. The gear 114 is movably sleeved inside the rectangular groove 111, and the teeth of the gear 114 are meshed with the teeth of the L-shaped tooth plate 110. A controller 115 is installed on the surface of the conveyor 101, and the motor 113 and the electric push rod 106 are both electrically connected to the controller 115.
[0027] In this embodiment, when it is necessary to quantitatively feed the raw materials for the production of medical rubber sleeves to the production equipment, the controller 115 is allowed to start the motor 113 and the electric push rod 106 first. At this time, the started motor 113 will directly drive the L-shaped toothed plate 110 to move under the cooperation of the gear 114, the rectangular hole 112 and the rectangular groove 111, and the moving L-shaped toothed plate 110 will drive the push plate 108 to move. At the same time, the started electric push rod 106 will drive the L-shaped plate 105 to move. When the L-shaped plate 105 moves to a point where it cannot move, the controller 115 will first turn off the electric push rod 106. At this time, the liquid raw material inside the guide hole 107 will be directly discharged from the guide hole 107. The liquid flows out from the outlet of the guide hole 107 and falls into a liquid storage shell (the first one) on the conveyor 101 directly below. At the same time, the moving push plate 108 will also push out the liquid raw material inside the guide hole 107. When the push plate 108 moves to a point where it cannot move, the liquid raw material inside the guide hole 107 will be quickly diverted to the inside of the liquid storage shell. When there is no liquid raw material flowing out of the outlet of the guide hole 107, the controller 115 will again use the cooperation of the motor 113, the gear 114, the rectangular hole 112, the rectangular groove 111 and the L-shaped tooth plate 110 to allow the push plate 108 to reset and move. When the push plate 108 is about to reset to the initial position, the controller 115 will reset the push plate 108 to the initial position. The controller 115 will directly use the cooperation of the electric push rod 106 to reset the L-shaped plate 105 to the initial position. When the push plate 108 moves back to the initial position, the controller 115 will directly pause the motor 113, and the controller 115 will also start the conveyor 101. At the same time, the inside of the guide hole 107 will be filled with liquid raw materials again. When the conveyor 101 is started, the liquid storage shell filled with liquid raw materials will move under the action of the started conveyor 101. When the second liquid storage shell moves to the bottom of the guide hole 107, the controller 115 will first pause the conveyor 101, and then start the motor 113 and the electric push rod 106. At this time, the started The motor 113 and the electric push rod 106 will repeat the above operation again, quickly push out the liquid raw material filled in the guide hole 107, and guide it to the inside of the second liquid storage shell (at this time, the amount of liquid raw material in the second liquid storage shell is the same as the amount of liquid raw material in the first liquid storage shell, that is, quantitative transportation is achieved). When there is no liquid raw material flowing out of the outlet of the guide hole 107, the controller 115 will repeat the above operation again, reset the L-shaped plate 105 and the push plate 108 to their original positions, and move the second liquid storage shell on the conveyor 101 at the same time. In this way, the subsequent liquid storage shells (the third, fourth, fifth...) on the conveyor 101 can be injected with liquid raw materials.
[0028] The effect and working principle of the whole mechanism are as follows: when it is necessary to quantitatively feed the raw materials for the production of medical rubber sleeves to the production equipment, a certain amount of liquid raw materials with temperature (natural latex that has been prepared and heated for a period of time) is first injected into the storage shell 104. After the liquid raw materials are injected into the storage shell 104, a part of the liquid raw materials will enter the guide hole 107. When the guide hole 107 is completely filled with liquid raw materials, the controller 115 is first connected to the external power supply, and then the controller 115 is turned on, and then the use program and temperature threshold are set (the liquid is heated to a temperature with good fluidity). When everything is ready, the controller 115 will first start the motor 1 13 and the electric push rod 106, the started motor 113 will directly drive the L-shaped toothed plate 110 to move under the cooperation of the gear 114, the rectangular hole 112 and the rectangular groove 111, and the moving L-shaped toothed plate 110 will drive the push plate 108 to move. At the same time, the started electric push rod 106 will drive the L-shaped plate 105 to move. When the L-shaped plate 105 moves to a point where it cannot move, the controller 115 will first turn off the electric push rod 106. At this time, the liquid raw material inside the guide hole 107 will directly flow out from the outlet of the guide hole 107 and fall into a liquid storage shell (the first one) on the conveyor 101 directly below. At the same time, the moving push plate 108 will also push the liquid raw material inside the guide hole 107 out. When the push plate 10 When the push plate 108 moves to a position where it cannot move, the liquid raw material in the guide hole 107 will be quickly guided to the inside of the liquid storage shell. When there is no liquid raw material flowing out of the outlet of the guide hole 107, the controller 115 will again use the cooperation of the motor 113, the gear 114, the rectangular hole 112, the rectangular groove 111 and the L-shaped toothed plate 110 to allow the push plate 108 to reset and move. When the push plate 108 is about to reset to the initial position, the controller 115 will directly use the cooperation of the electric push rod 106 to allow the L-shaped plate 105 to reset to the initial position. When the push plate 108 moves back to the initial position, the controller 115 will directly pause the motor 113, and the controller 115 will also start the conveyor 101. At the same time, the inside of the guide hole 107 will also reset and return to the initial position. When the second liquid storage shell is filled with liquid raw materials for the second time, when the conveyor 101 is started, the liquid storage shell filled with liquid raw materials will move under the action of the started conveyor 101. When the second liquid storage shell moves to the bottom of the guide hole 107, the controller 115 will first pause the conveyor 101, and then start the motor 113 and the electric push rod 106. At this time, the started motor 113 and the electric push rod 106 will repeat the above operation again, and quickly push out the liquid raw materials filled in the guide hole 107, and guide them to the inside of the second liquid storage shell (at this time, the amount of liquid raw materials in the second liquid storage shell is the same as that in the first liquid storage shell). When there is no liquid raw material flowing out of the outlet of the guide hole 107, the controller 115 will repeat the above operation again.The L-shaped plate 105 and the push plate 108 are reset to their original positions, and the second liquid storage shell on the conveyor 101 is moved. This reciprocating process allows the subsequent liquid storage shells (the third, fourth, fifth, etc.) on the conveyor 101 to be injected with liquid raw materials. When the first liquid storage shell filled with liquid raw materials reaches directly below the hollow block 213, a liquid storage shell that needs to be injected with liquid raw materials appears directly below the guide hole 107. At this time, the controller 115 will directly start the hot air blower 202, the two servo electric cylinders 211 and the temperature sensor 209. When the hot air blower 202 is started, the hot air blower 202 that is started at this time will directly inhale and heat the air in the environment, and then transport the heated air to the inside of the outlet pipe 203. Then the hot air will be directly transported to the interior of the space composed of the rectangular plate 204, the partition 205 and the placement shell 201, and then transported to the interior of the installation hole 206, and then transported to the interior of the fixing ring 208. When the hot air passes through the mesh of the filter 207, the dust or fine particles in the hot air will be filtered out. When more dust or smaller particles accumulate on the surface of the filter 207, the large dust composed of dust or smaller particles will fall into the interior of the space composed of the rectangular plate 204, the partition 205 and the placement shell 201 under the action of its own weight. When the hot air enters the interior of the fixing ring 208, the temperature sensor 209 will detect the temperature of the hot air, and then the detected hot air will be connected to the With the cooperation of the cover 218, it is transported to the inside of the insulation hose 217, then transported to the inside of the air intake pipe 216, and then transported to the inside of the hollow block 213, and then discharged from the inside of the hollow block 213 and dispersed into the environment. At the same time, the temperature sensor 209 will directly transmit the detected temperature data to the controller 115 in the form of an electrical signal, and then the controller 115 will compare the received temperature data with the temperature threshold value set in advance by the controller 115. When the temperature data received by the controller 115 is lower than the temperature threshold value set in advance by the controller 115, the controller 115 will continue to increase the heating temperature of the hot air blower 202. When the temperature data received by the controller 115 is lower than the temperature threshold value set in advance by the controller 115, the controller 115 will continue to increase the heating temperature of the hot air blower 202. When the temperature thresholds set previously are the same, the controller 115 will save the heating temperature of the hot air blower 202 and continue to start the hot air blower 202. At the same time, the controller 115 will also start the two servo electric cylinders 211 at the same time. At this time, the two started servo electric cylinders 211 will drive the hollow block 213, the double-hole plate 215, the two sealing rings 214 and the air inlet pipe 216 to move downward at the same time under the cooperation of the two sets of mounting frames 210 and the two connecting plates 212. When the liquid storage shell containing liquid raw materials is sleeved between the insides of the two sealing rings 214, the controller 115 will pause the two servo electric cylinders 211 at the same time. At this time, under the action of continuous injection of hot air into the hollow block 213, the temperature of the liquid raw material in the liquid storage shell will continue to rise.At the same time, the hot air transported to the interior of the hollow block 213 will also be discharged from the interior of the hollow block 213 and discharged into the environment under the cooperation of the other circular hole of the double-hole plate 215 and the exhaust port on the hollow block 213. When the liquid raw material inside the liquid storage shell is heated for a period of time, the controller 115 will first turn off the hot air blower 202, and then through the cooperation of two servo electric cylinders 211, two sets of mounting frames 210 and two connecting plates 212, the hollow block 213, the double-hole plate 215, the two sealing rings 214 and the air inlet pipe 216 are simultaneously reset to their original positions. When the hollow block 213, the double-hole plate 215, the two sealing rings 214 and the air inlet pipe 216 are all reset to their original positions, the fluidity of the liquid raw material in the heated liquid storage shell is just right (avoiding the problem that the liquid raw material is not easy to be discharged from the liquid storage shell due to low fluidity). At the same time, when the raw materials inside the liquid storage shell are heated, the liquid raw materials are injected into the new liquid storage shell directly below the guide hole 107. When the raw materials inside the liquid storage shell are heated, the liquid storage shell directly below the guide hole 107 also completes the liquid raw materials injection operation. Then the controller 115 will repeat the above steps again, inject the liquid raw materials into the next liquid storage shell, and heat the next liquid storage shell filled with liquid raw materials. When the liquid storage shell filled with the liquid raw materials with better fluidity after heating reaches the discharge end of the conveyor 101, the liquid raw materials with better fluidity in the liquid storage shell will flow away directly and quickly, and enter the interior of the guide shell 102 without leaving any residue, and then be diverted to the production equipment for use.
