[0032] Combine the following Figures 1 to 6 The production equipment of the gravure blanket of the present invention will be described.
[0033] like Figures 1 to 4 As shown, the production equipment of the gravure rubber blanket of the present invention comprises: a bracket 101, two symmetrical calendering components, two first recovery boxes 110 and two second recovery boxes 113.
[0034] Each calendering assembly corresponds to a first recovery box 110 and a second recovery box 113 .
[0035] Each calendering assembly includes: a calendering belt 104 , a piercing device, a refrigeration component 108 , a heating component 111 and a cleaning wheel 112 .
[0036] The piercing device is disposed on a first side (i.e., Figure 3 and Figure 4 The left side in the figure) and squeezes the calendering belt 104 and punctures the rubber crumbs 115 on the calendering belt 104.
[0037] The cooling member 108 is disposed on a first side of the outer side of the calendering belt 104 to cool the punctured rubber crumbs 115 .
[0038] The first recovery box 110 is disposed on the second side (ie, Figure 3 and Figure 4 on the right side of the figure) to recover the cooled rubber crumbs 115.
[0039] The heating member 111 is disposed at a second side of the outer side of the calendering belt 104 to heat the rubber crumbs 115 that are not recovered by the first recovery box 110 .
[0040] The sweeping wheel 112 is disposed on a second side of the outer side of the calendering belt 104 , and presses the calendering belt 104 .
[0041] The second recovery box 113 is disposed on a side of the cleaning wheel 112 away from the calendering belt 104 , and the cleaning wheel 112 can clean the heated rubber crumbs 115 into the second recovery box 113 .
[0042] The present invention sets a puncturing device and a refrigeration component 108 on the first side of the calendering belt 104, and sets a first recovery box 110, a heating component 111, a cleaning wheel 112 and a second recovery box 113 on the second side of the calendering belt 104. The puncturing device is used to puncture the rubber crumbs 115 on the calendering belt 104, and the refrigeration component 108 is used to cool the punctured rubber crumbs 115, so that the rubber crumbs 115 harden. When the hardened rubber crumbs 115 are transferred from the first side of the calendering belt 104 to the second side at the first end of the calendering belt 104, the rubber crumbs 115 are tilted because the bending direction of the rubber crumbs 115 is different from that of the first end of the calendering belt 104 and the curvature of the first end of the calendering belt 104 is larger, so that the rubber crumbs 115 are collected by the first recovery box 110. Then, the rubber crumbs 115 not collected by the first recovery box 110 are heated by the heating component 111 to soften the rubber crumbs 115 , and the softened rubber crumbs 115 are cleaned to the second recovery box 113 by the cleaning wheel 112 , thereby completing the collection of the rubber crumbs 115 on the calendering belt 104 .
[0043] For example, Figure 1 As shown, a first motor 102 and a second motor 103 are mounted on the bracket 101. The first motor 102 is used to drive the calendering roller 105 described below to rotate around the axis of the calendering roller 105 itself, and the second motor 103 is used to drive the crushing roller 106 described below to rotate around the axis of the crushing roller 106 itself, and drive the cleaning wheel 112 to rotate around the axis of the cleaning wheel 112 itself. Two first motors 102 can be provided, one of which drives the calendering roller 105 above, and the other first motor 102 drives the calendering roller 105 below, so that the two calendering rollers 105 rotate in opposite directions. One first motor 102 can also be provided, and the two calendering rollers 105 are controlled to rotate in opposite directions through a transmission device.
[0044] For example, Figure 3 and Figure 4 As shown, the calendering assembly further includes: a calendering roller 105 and an auxiliary roller 109 .
[0045] The calendering roller 105 and the auxiliary roller 109 are mounted on the bracket 101. The calendering rollers 105 of the two calendering assemblies are located between the auxiliary rollers 109 of the two calendering assemblies. The calendering belt 104 is wound around the calendering rollers 105 and the auxiliary rollers 109, that is, the calendering rollers 105 and the auxiliary rollers 109 are located on the inner side of the calendering belt 104.
[0046] The calendering roller 105 can rotate around its own axis under the drive of the first motor 102 to drive the calendering belt 104 to rotate. During the rotation of the calendering belt 104, the calendering belt 104 drives the auxiliary roller 109 to rotate around its own axis. The portion of the calendering belt 104 wound around the auxiliary roller 109 constitutes the first end of the calendering belt 104. The curvature of the auxiliary roller 109 is greater than a predetermined value, so that the curvature of the first end of the calendering belt 104 is larger, thereby causing the rubber crumbs 115 to tilt up so as to be collected by the first recovery box 110.
[0047] The auxiliary roller 109 of the upper calendering assembly is located above the calendering roller 105 , and the auxiliary roller 109 of the lower calendering assembly is located below the calendering roller 105 .
[0048] For example, Figure 4 and Figure 6 As shown, the puncturing device includes: a crushing roller 106 and a plurality of crushing needle assemblies.
[0049] The crushing roller 106 is cylindrical and is located on the first side of the outer side of the calendering belt 104 ( Figure 4 and Figure 6 The crushing roller 106 squeezes the calendering belt 104. The crushing roller 106 can rotate around its own axis under the drive of the second motor 103.
[0050] A plurality of crushing needle assemblies are arranged on the outer circumferential surface of the crushing roller 106 and have a predetermined interval in the circumferential direction of the crushing roller 106. Each crushing needle assembly includes a plurality of crushing needles 1061 spaced apart along the axial direction of the crushing roller 106. The crushing needles 1061 can puncture the rubber crumbs 115 on the calendering belt 104 when they come into contact with the rubber crumbs 115. Specifically, when the crushing roller 106 rotates around its own axis, the crushing needles 1061 can come into contact with the rubber crumbs 115 on the calendering belt 104 to effectively puncture the rubber crumbs 115 and crush them into particles of smaller sizes, which helps to improve the efficiency of subsequent processing steps.
[0051] Among them, multiple crushing needle assemblies have predetermined intervals in the circumferential direction of the crushing roller 106. As the crushing roller 106 rotates, the crushing needle assemblies at different positions in the circumferential direction can sequentially and repeatedly puncture the rubber crumbs 115 on the calendering belt 104, thereby achieving sustainability of the puncture.
[0052] In each crushing needle assembly, a plurality of crushing needles 1061 are spaced apart along the axial direction of the crushing roller 106 , which can ensure that the rubber crumbs 115 at any position in the width direction of the calendering belt 104 are punctured to avoid omission.
[0053] For example, Figure 4and Figure 6 As shown, the puncturing device also includes a plurality of telescopic detection rods 1062 , each telescopic detection rod 1062 is arranged corresponding to a crushing needle 1061 , and the telescopic detection rod 1062 is installed on the outer peripheral wall of the crushing roller 106 and can slide along the radial direction of the crushing roller 106 .
[0054] The gravure rubber blanket production equipment further includes: a detection component 107 and a controller (not shown in the figure).
[0055] The detection component 107 is fixed on the bracket 101 and is located inside the crushing roller 106. It does not rotate with the crushing roller 106. The detection component 107 has a plurality of sensors 1071 corresponding to the detection telescopic rods 1062. The sensors 1071 face the calendering belt 104. The detection component 107 corresponds to the detection telescopic rods 1062 one by one.
[0056] The controller is electrically connected to the sensor 1071 .
[0057] When the detection telescopic rod 1062 contacts the rubber crumbs 115 on the calendering belt 104 , the rubber crumbs 115 can push the detection telescopic rod 1062 to slide inward along the radial direction of the crushing roller 106 , so that the sensor 1071 can detect the movement of the detection telescopic rod 1062 , thereby generating a trigger signal.
[0058] For example, the sensor 1071 may be a pressure sensor. When the detection telescopic rod 1062 slides inwardly along the radial direction of the crushing roller 106, the detection telescopic rod 1062 contacts the pressure sensor, thereby causing the pressure sensor to generate a trigger signal. The pressure sensor is only an example, and the type of the sensor 1071 is not limited thereto. It can be any form in the prior art as long as it can achieve the above functions.
[0059] The sensor 1071 can send the generated trigger signal to the controller.
[0060] In the axial direction of the crushing roller 106, the detection telescopic rods 1062 are distributed at intervals, and the sensors 1071 are also distributed at intervals, which can accurately detect the specific position of the rubber crumbs 115 in the axial direction of the crushing roller 106 (that is, the width direction of the calendering belt 104), thereby providing precise positioning for the subsequent cooling process, heating process and oiling process, so as to improve the efficiency of the cooling process, heating process and oiling process, thereby reducing production costs.
[0061] Exemplarily, the detection telescopic rod 1062 is configured to elastically return outward along the radial direction of the crushing roller 106, so that when the detection telescopic rod 1062 is no longer in contact with the rubber crumbs 115 on the calendering belt 104, it can slide outward along the radial direction of the crushing roller 106, thereby achieving reset to facilitate the subsequent detection process. This design ensures the continuity and efficiency of the detection process, making the entire production process smoother and more efficient.
[0062] For example, Figures 4 to 6 As shown, the refrigeration component 108 is disposed on a side of the crushing roller 106 away from the calendering roller 105. The refrigeration component 108 includes a refrigeration housing 1081, a plurality of first fans 1082 and a plurality of refrigerators 1083.
[0063] The refrigeration housing 1081 has a plurality of first accommodating cavities 1084 , and the first accommodating cavities 1084 have openings facing the calendering belt 104 .
[0064] A plurality of refrigerators 1083 are spaced apart and distributed along the axial direction of the crushing roller 106, and each refrigerator 1083 is disposed at the opening of the corresponding first accommodating cavity 1084 and is electrically connected to the controller. The refrigerator 1083 can generate cold energy under the control of the controller. The controller can individually control one or more refrigerators 1083 to generate cold energy.
[0065] The first fans 1082 are arranged corresponding to the refrigerators 1083. Each first fan 1082 is arranged on a side of a corresponding refrigerator 1083 away from the calendering belt 104, and is electrically connected to the controller, and can generate wind blowing toward the refrigerator 1083. Specifically, each first fan 1082 is installed in a corresponding first accommodating cavity 1084. The controller can independently control one or more first fans 1082 to operate to generate wind.
[0066] Under the control of the controller, the first fan 1082 generates wind to blow toward the refrigerator 1083 to blow the cold energy generated by the refrigerator 1083 toward the calendering belt 104, thereby cooling the rubber crumbs 115 on the calendering belt 104, so that the rubber crumbs 115 harden.
[0067] The specific form of the refrigeration component 108 is not limited to the above-mentioned form, and can be any form in the prior art as long as it can achieve the above-mentioned function.
[0068] The number of the first fans 1082 and the number of the refrigerators 1083 are equal to the number of the above-mentioned detection telescopic rods 1062 and the number of the sensors 1071 .
[0069] For example, Figures 4 to 6As shown, the heating component 111 is disposed on a side of the cleaning wheel 112 away from the calendering roller 105. The heating component 111 includes a heating housing 1111, a plurality of second fans 1112 and a plurality of heaters 1113.
[0070] The heating housing 1111 has a plurality of second accommodating cavities 1114 , and the second accommodating cavities 1114 have openings facing the calendering belt 104 .
[0071] A plurality of heaters 1113 are spaced apart and distributed along the axial direction of the crushing roller 106. Each heater 1113 is disposed at the opening of the corresponding second accommodating cavity 1114 and is electrically connected to the controller. The heater 1113 can generate heat under the control of the controller. The controller can individually control one or more of the heaters 1113 to generate heat.
[0072] The second fans 1112 are arranged corresponding to the heaters 1113. Each second fan 1112 is arranged on a side of a corresponding heater 1113 away from the calendering belt 104, and is electrically connected to the controller, and can generate wind blowing toward the heater 1113. Specifically, each second fan 1112 is installed in a corresponding second accommodating cavity 1114. The controller can independently control one or more second fans 1112 to operate to generate wind.
[0073] Under the control of the controller, the second fan 1112 generates wind blowing toward the heater 1113 to blow the heat generated by the heater 1113 toward the calendering belt 104, thereby heating the rubber crumbs 115 remaining on the calendering belt 104 to soften the rubber crumbs 115.
[0074] For example, Figure 3 As shown, the production equipment of the gravure rubber blanket of the present invention further includes an oiling assembly 114 , which is fixedly connected to the bracket 101 and can spray oil onto the calendering belt 104 .
[0075] Exemplarily, the oiling assembly 114 includes a plurality of oiling units distributed along the axial direction of the crushing roller 106 (i.e., the width direction of the calendering belt 104), and each oiling unit is electrically connected to the controller. Each oiling unit corresponds to the detection telescopic rod 1062 and the sensor 1071 one by one. The controller can independently control one or more oiling units to spray on the calendering belt 104, so as to accurately control the amount of oil sprayed in the width direction of the calendering belt 104, thereby avoiding excessive use and unnecessary loss of ink in the width direction of the calendering belt 104. Such a design not only improves production efficiency, but also reduces production costs, making the entire gravure rubber blanket production process more environmentally friendly and economical.
[0076] The cleaning wheel 112 can rotate around its own axis under the drive of the second motor 103 .
[0077] like Figure 3 and Figure 4 As shown, the first recovery box 110 is arranged on a side of the heating component 111 away from the cleaning wheel 112, and has an opening toward the calendering belt 104. The bottom wall of the first recovery box 110 corresponding to the upper calendering assembly is inclined outward from top to bottom, so that the rubber crumbs 115 can more easily fall into the first recovery box 110 from the opening. The bottom wall of the first recovery box 110 corresponding to the lower calendering assembly is inclined inward from top to bottom, so that the rubber crumbs 115 can more easily fall into the first recovery box 110 from the opening.
[0078] The second recovery box 113 has an opening facing the calendering belt 104 , and a bottom wall of the second recovery box 113 is inclined outward from top to bottom so that the rubber crumbs 115 can fall into the second recovery box 113 more easily from the opening.
[0079] The present invention also provides a method for preparing a gravure rubber blanket, comprising:
[0080] S100, using a piercing device to pierce the rubber crumbs 115 on the calendering belt 104.
[0081] S200 , utilizing the refrigeration component 108 to cool the punctured rubber debris 115 .
[0082] S300 , using the first recovery box 110 to recover the cooled eraser crumbs 115 .
[0083] S400 , heating the eraser scraps 115 that are not recovered by the first recovery box 110 by using the heating component 111 .
[0084] S500 , the heated eraser crumbs 115 are cleaned into the second recovery box 113 by using the cleaning wheel 112 .
[0085] Specifically, under the drive of the first motor 102, the upper calendering roller 105 moves along the first direction (i.e. Figure 3 and Figure 4 The calendering roller 105 at the bottom moves along the second direction (i.e., the clockwise direction in the middle of the calendering belt 104). Figure 3 and Figure 4 The calendering belt 104 below moves in the second direction.
[0086] The gravure rubber blanket passes between the two calendering belts 104 and moves from right to left under the drive of the two calendering belts 104. The calendering belts 104 squeeze the gravure rubber blanket to complete the production work of the gravure rubber blanket.
[0087] If there are rubber crumbs 115 on the calender belt 104, when passing through the crushing roller 106, the rubber crumbs 115 will contact the crushing needle 1061 and be punctured by the crushing needle 1061. While contacting the crushing needle 1061, the detection telescopic rod 1062 corresponding to the crushing needle 1061 will also contact the crushing needle 1061, so that the detection telescopic rod 1062 slides inward along the radial direction of the crushing roller 106, so that the sensor 1071 can detect the movement of the detection telescopic rod 1062, thereby generating a trigger signal, and sending the trigger signal to the controller.
[0088] Driven by the second motor 103, the upper crushing roller 106 moves along the second direction (i.e. Figure 3 and Figure 4 The lower crushing roller 106 rotates along the first direction (i.e., the counterclockwise direction in the figure). Figure 3 and Figure 4 The crushing roller 106 rotates around its own axis (clockwise direction).
[0089] Under the drive of the second motor 103, the upper cleaning wheel 112 and the lower cleaning wheel 112 move along the first direction (i.e. Figure 3 and Figure 4 The cleaning wheel 112 rotates in a clockwise direction around the axis of the cleaning wheel 112 itself.
[0090] The controller controls the refrigeration component 108 to refrigerate according to the trigger signal, specifically, to refrigerate the position where the rubber crumbs 115 are present, so that the rubber crumbs 115 are hardened.
[0091] When the hardened rubber crumbs 115 pass through the auxiliary roller 109 , the rubber crumbs 115 are tilted up because the bending direction of the rubber crumbs 115 is different from that of the auxiliary roller 109 and the curvature of the auxiliary roller 109 is large, and thus are collected by the first recovery box 110 .
[0092] The eraser crumbs 115 not collected by the first recovery box 110 are heated when passing through the heating component 111. Specifically, the heating component 111 heats the position where the eraser crumbs 115 are present under the control of the controller, so that the eraser crumbs 115 are softened.
[0093] The softened rubber crumbs 115 are swept by the sweeping wheel 112 to the second recovery box 113 , thereby completing the collection of the rubber crumbs 115 on the calendering belt 104 .
[0094] The calendering belt 104 continues to rotate, and the oiling assembly 114 applies oil to the calendering belt 104. Specifically, under the control of the controller, the oiling assembly 114 applies oil to the position of the calendering belt 104 where rubber crumbs 115 once existed, thereby reducing the possibility of rubber crumbs 115 sticking to this area in subsequent cycles.
[0095] To more clearly illustrate the precise positioning function, the detection component 107 has 10 sensors 1071, the puncturing device has 10 detection telescopic rods 1062 and 10 crushing needles 1061, the refrigeration shell 1081 has 10 first accommodating chambers 1084, the refrigeration component 108 includes 10 first fans 1082 and 10 refrigerators 1083, the heating shell 1111 has 10 second accommodating chambers 1114, the heating component 111 includes 10 second fans 1112 and 10 heaters 1113, and the oiling component 114 includes 10 oiling monomers. That is, the calendering belt 104 is divided into 10 detection areas in its width direction.
[0096] Assume that there are rubber crumbs 115 at positions corresponding to the first and fifth crushing needles 1061 and the detection telescopic rod 1062 in the width direction of the calender belt 104 (ie, the axial direction of the crushing roller 106 ).
[0097] When the rubber crumbs 115 pass through the crushing roller 106, the rubber crumbs 115 will come into contact with the first and fifth crushing needles 1061 and the detection telescopic rod 1062, and be punctured by the crushing needles 1061, while causing the first and fifth detection telescopic rods 1062 to slide inward along the radial direction of the crushing roller 106, causing the first and fifth sensors 1071 to generate trigger signals and send the trigger signals to the controller.
[0098] The controller determines that there are rubber crumbs 115 in the first and fifth detection areas according to the trigger signal, and generates corresponding control signals to control the subsequent cooling, heating and oiling processes. Specifically, the controller generates a first control signal, a second control signal and a third control signal according to the trigger signal, and sends the first control signal to the cooling component 108, the second control signal to the heating component 111, and the third control signal to the oiling component 114.
[0099] The controller stores three preset times, specifically including: a first preset time for the rubber crumbs 115 to be transferred from the crushing roller 106 to the refrigeration component 108, a second preset time for the rubber crumbs 115 to be transferred from the crushing roller 106 to the heating component 111, and a third preset time for the rubber crumbs 115 to be transferred from the crushing roller 106 to the oiling component 114. The specific preset time can be calculated based on the rotation speed of the calender belt 104 and the rotation distances from the crushing roller 106 to the refrigeration component 108, the heating component 111 and the oiling component 114, respectively. For the convenience of expression, the moment when the rubber crumbs 115 pass through the crushing roller 106 is defined as the initial moment, the moment when the rubber crumbs 115 pass through the refrigeration component 108 is defined as the T1 moment, that is, the period from the initial moment to the T1 moment is the first predetermined time, the moment when the rubber crumbs 115 pass through the heating component 111 is defined as the T2 moment, that is, the period from the initial moment to the T2 moment is the second predetermined time, and the moment when the rubber crumbs 115 pass through the oiling component 114 is defined as the T3 moment, that is, the period from the initial moment to the T3 moment is the third predetermined time.
[0100] Under the control of the first control signal, only the first and fifth refrigerators 1083 start to generate cold at time T1, and only the first and fifth first fans 1082 start to generate wind blowing toward the refrigerators 1083 at time T1, so as to blow the cold toward the first and fifth detection areas of the calendering belt 104. At time T1, the rubber crumbs 115 just pass through the refrigeration component 108, so that the cold cools the rubber crumbs 115 on the calendering belt 104, so that the rubber crumbs 115 harden. This design avoids the waste of cold in the width direction of the calendering belt 104. Here, the duration of the refrigerator 1083 generating cold and the duration of the first fan 1082 generating wind can be flexibly changed according to actual conditions, so that the hardening effect of the rubber crumbs 115 can be guaranteed, and the refrigeration component 108 can be guaranteed to stop working after the rubber crumbs 115 leave the position, so as to save costs.
[0101] Under the control of the second control signal, only the first and fifth heaters 1113 start to generate heat at time T2, and only the first and fifth second fans 1112 start to generate wind blowing toward the heaters 1113 at time T2, so as to blow the cold toward the first and fifth detection areas of the calender belt 104. At time T2, the rubber crumbs 115 just pass through the heating component 111, so that the heat heats the rubber crumbs 115 on the calender belt 104, so that the rubber crumbs 115 soften. This design avoids the waste of heat in the width direction of the calender belt 104. Here, the duration of the heater 1113 generating heat and the duration of the second fan 1112 generating wind can be flexibly changed according to actual conditions, so that the softening effect of the rubber crumbs 115 can be guaranteed, and the heating component 111 can be guaranteed to stop working after the rubber crumbs 115 leave this position, so as to save costs.
[0102] Under the control of the third control signal, only the first and fifth oil-coating monomers start to be oiled at time T3. At time T3, the position of the calender belt 104 where the rubber crumbs 115 originally existed just passes through the oiling assembly 114, so that the first and fifth oil-coating monomers oil the first and fifth oil-coating monomers on the calender belt 104. The oiling time here can be flexibly changed according to actual conditions, so as to ensure the oiling effect and avoid excessive use and unnecessary loss of ink in the rotation direction of the calender belt 104, so as to save costs.
